Scientists at Dongguk University propose a network effect-based model that enhances business intelligenceIt utilizes the influence-based social exchange and two-step flow of information theories to collect reliable user dataThere is a need to improve the quality of user data for making effective business decisions. To this end, researchers in Korea propose a network effect-based reasoning model that directly collects meaningful data by applying the influence-based social exchange and two-step flow of information theories. The model can enhance business intelligence and facilitate big data analysis.In the age of big data, corporations are increasingly using business intelligence—collecting, analyzing, and utilizing user data—for decision-making. It has been made possible through social media platforms and technological innovations, which enable easy data accumulation and storage at low costs.The effectiveness of business intelligence depends upon the quality of data. Big data has a lot of noise, and only meaningful inputs can lead to meaningful outputs. Therefore, reliable user data is essential. The existing ways to improve the reliability of already collected data, however, are not efficient.To address this issue, Dr. Kihwan Nam, Assistant professor of Management Information Systems in the Business School of Dongguk University, Korea, and his colleague have recently presented a new theoretical model that secures meaningful information by improving data reliability during the collection stage. Their study reporting the model was made available online on 1 June 2022 and published in Volume 205 of Expert Systems With Applications on 1 November 2022.“The model, based on the network effect, applies both the influence-based social exchange theory and the two-step flow of information theory. In it, initially, a user evaluates and recommends a product to a group. Its recommendation range depends on the user’s influence. The user, aware of their influence, will try to increase it by getting positive feedback from the group, thereby acting as an ‘opinion leader’ and generating data that reliably indicates popular products,” explains Dr. Nam.The researchers verified the effectiveness of their reasoning model by collecting user data from an online media content platform and applying the model to its recommendation system. They found that its performance—data quality and user satisfaction—improved two to five times. That led to an upsurge in the number of users on the platform.Dr. Nam is hopeful about the future potential of their work. “It demonstrates theoretical, technical, and practical aspects of reliable data collection, making it valuable for corporations. Not only will our proposed model enhance business intelligence, but it will also help extract meaningful information for various other applications involving big data analysis.”ReferenceAuthors: Nohkyum Kyeong1, Kihwan Nam2Title of original paper: Mechanism design for data reliability improvement through network-based reasoning modelJournal: Expert Systems With ApplicationsDOI: 10.1016/j.eswa.2022.117660Affiliations: 1College of Business Management Engineering Department, KAIST, Korea2Management Information Systems, Business School, Dongguk University, Korea*Corresponding author’s email: namkh@dongguk.edu*Corresponding author’s home page: https://sites.google.com/view/namkiAbout Dongguk UniversityDongguk University, founded in 1906, is located in Seoul, South Korea.

‘Improvements in incentives and financial performance following ESG performance’... Proven through research resultsDongguk University (President Yoon Sung-Yee) announced on the 11th November that the research by Professor Jeong Seon-moon of the Department of Accounting at Dongguk University Business School was published in the October 2022 issue (Volume 68, No. 10) of “Management Science,” the world’s most prestigious academic journal of business administration.“Management Science” is one of the world's most prestigious academic journals in the field of business administration. It is an academic journal that has published many papers by world-renowned economists and management scholars including Nobel Prize winners Merton Miller, Franco Modigliani, Kenneth Arrow, Robert Lucas, James Heckman, Daniel Kahneman, Eugene Fama, Harry Markowitz, and William Sharp (SSCI, IF=6.172).Professor Jeong participated as the first author of this thesis, and the corresponding author, Seoul National University Business School Professor Shin Jae-yong, co-authored the paper. (Thesis source: https://doi.org/10.1287/mnsc.2021.4232)Providing financial rewards for ESG performance, an effective ESG improvement method... Proven by domestic researchers for the first timeThe significance of ESG (environmental, social, and governance) management is becoming more prominent as the importance of non-financial performance management grows worldwide. Domestic and foreign companies are making various efforts, such as expanding ESG-related disclosures externally and establishing ESG-related board committees internally.Through this study, Professor Jeong studied the effectiveness of financial reward methods to improve ESG performance more systematically. According to Professor Jeong's research, it has been scientifically proven that social performance increases significantly when the social performance of social enterprises is measured and financial reward is provided in proportion to the measured performance. For the first time, a domestic research team has proven that systematically measuring ESG performance and providing financial compensation is an effective ESG improvement method.Professor Jeong's research was conducted based on the data of companies subject to the SPC (Social Performance Compensation) project, which was implemented by SK Group's Social Value Research Institute in 2015. The SPC project is a project that quantifies the performance of social enterprises based on the systematic social performance measurement system developed by SK, and grants financial incentives proportional to the performance measured in currency basis. For example, if the social performance related to the employment of a social enterprise that employs people with developmental disabilities is measured as KRW 1 billion according to a sophisticated measurement formula, KRW 250 million, equivalent to 25% of the KRW 1 billion, is paid as an incentive.Professor Jeong emphasized that "the ultimate goal of measurement-based incentives is motivation." In other words, if ESG performance can be quantified with a standardized evaluation and measurement system, it is possible to provide financial rewards for ESG performance in the same way as providing bonuses for financial performance. “Just as managers work hard to increase financial profits when they receive bonuses in proportion to ROA (return on assets), they will naturally work hard to increase social performance if social performance is properly measured and rewarded,” he argued. The research also proved that the social performance of social enterprises improved statistically significantly after being linked to incentives, stating that "Financial compensation according to performance leads to motivation of organizational members."Financial rewards for ESG are not always effectiveHowever, financial rewards are not always effective. There are many cases among social enterprises, unlike for-profit enterprises, wherein people who are not accustomed to financial incentives and who pursue social missions gather to form an organization. According to Professor Jeong's research, financial rewards may have a less motivating effect in value-oriented organizations that value social missions. Professor Jeong said, "In a value-oriented organization, rather than receiving and distributing financial rewards to executives and employees, if they are used for reinvestment for ESG, the effect of improving employee performance can be maximized." It was also emphasized that whether to do it is an important issue in terms of motivation. In other words, financial incentives do not have a uniform motivating effect in all companies; the effect varies depending on the organizational culture and how financial rewards are used.Providing financial incentives to ESG improves financial performance as wellProfessor Jeong's research also found that financial rewards for ESG can improve financial performance. Companies with high task complementarity between social and financial performances have a business model in which financial profits increase as social performance improves. For example, local cooperatives purchase agricultural products from local small farmers at a reasonable price to create social outcomes that revive the local economy. On the other hand, it has a business model that improves financial performance while simultaneously reducing distribution margins because it can easily secure and sell local agricultural products directly to consumers. In the case of companies with high task complementarity like this, it has been statistically proven that financial incentive is significantly improved even if financial reward is provided only for social performance.Korean ESG management analyzed and published in the world's most prestigious academic journalProfessor Jeong's research is significant as it presented a method for systematically managing ESG performance. Non-financial performance, such as ESG, was perceived as difficult to quantify and therefore difficult to motivate with financial incentives. Professor Jeong's research proved that ESG performance can be significantly improved if it is measured based on a systematic measurement system and financially compensated in proportion to the objectively measured performance. It was also scientifically revealed that financial incentives do not have uniform effects in all companies, but that the effects vary depending on the organizational culture and incentive usage. They also found that providing financial rewards to ESG performance can simultaneously improve financial performance under certain conditions.Professor Jeong said, “I am delighted that a paper analyzing an incentive experiment uniquely conducted in Korea was published in ‘Management Science,’ the world’s most prestigious academic journal.”

Dongguk University Research Team led by Professor Changsun ChoiDevelopment of Biomimetic-based High-output Hydro-actuatorFrom left to right:Changsun Choi, Professor at the Department of Convergence Energy and New Material Engineering; Wonkyung Son, Researcher; Jaemyeong Lee, Researcher○ The research team led by Changsun Choi, Professor at the Department of Convergence Energy and New Material Engineering, Dongguk University, Seoul, South Korea (corresponding author), and Sungwu Cheon, Professor at the Department of Electronics and Information Engineering at Korea University, Seoul, South Korea (co-corresponding author), was successful in overcoming the limitations of a conventional hydro-actuator by developing a high-output, high-power hydro-actuator with a fast electrothermal recovery capability.○ A Geraniaceae plant is usually straight and long, but it twists itself and becomes spring-like when exposed to a dry environment. When it is twisted to the maximum extent, it bounces out to spread its seeds. Under rainy conditions, contact with a rain droplet causes it to spin and dig into the ground like a drill. Professor Choi’s research team studied the moisture-triggered spinning mechanics of such a plant to develop a fiber-type hydro-actuator.○ An actuator is a switch or a motor device that switches its physical state according to electrical signal changes. A fiber-type hydro-actuator that uses water from its surroundings as a source of stimulant is highly usable in various fields, such as soft robotics, because of its silk-like soft characteristics. However, existing hydro-actuators have low output values and require long operational time owing to their substantially slow recovery processes that contrast with their sensitive reactions.○ To solve this, the research team took inspiration from the moisture-activated self-twisting characteristic of a stork’s bill plant and designed an actuator with a fast electrothermal recovery. This newly developed actuator based on a carbon nanotube fiber featuring both high water reactivity and an electrothermal property demonstrated 120 times (143.8 W/kg) greater ultrahigh power density at an applied voltage of 5 V and at an operating speed that is 15 times greater than that of conventional hydro-actuators. It also showed no performance degradation, even at a very high internal temperature (102°C), through repeated cycle testing. Thus, it exhibited outstanding mechanical and thermal durability.○ Professor Choi states, “The significance of this research is the development of a high-performance hydro-actuator using the excellent electrothermal characteristics of a carbon nanotube treated to exhibit sensitive moisture reactivity.” He showed anticipation by continuing to state, “This newly developed electrothermal-recovering hydro-actuator is very powerful and has high operational speed, which makes it ideal to be utilized in the converging field of the biomedical industry and for applications `in artificial muscles, smart fabrics, prosthetics, and artificial fingers.”○ For this research, various groups of personnel participated, including (but not limited to) Wonkyung Son, researcher (first author), Shihyeong Kim, Ph.D. (Korea Institute of Industrial Technology), Sungbeom Jo, Ph.D. (Korea Institute of Ceramic Engineering and Technology), and Dongseok Seo, Professor (Sungkyunkwan University). The research result was published online in March 2022 in Nano Letters (IF = 11.189), a journal of nanoscience technology, under the title <high-power biomimetic="" carbon="" coiled="" electrothermal="" fabricated="" fast="" from="" hydro-actuators="" nanotube="" recovery="" with="" yarns="">.(URL:https://pubs.acs.org/doi/10.1021/acs.nanolett.2c00250)</high-power>

Maneuvering Through a Pandemic: A Valuable Lesson in the Future ...

Maneuvering Through a Pandemic: A Valuable Lesson in the Future of Tourism and Hospitality Marketing, As Shown by Dongguk University Researchers COVID-19 has wreaked havoc on the tourism and hospitality industry, magnifying consumers’ adverse responses to crowding. Now, Dongguk University researchers demonstrated that consumers display diminished preferences for crowded venues, especially under high salience of COVID-19. However, this tendency reversed in consumers seeking unique, non-conforming experiences. These findings would help marketers reinvent their strategies to adapt to the new preferences of the traveler, such as promoting the notion of vacancy and unpopularity in advertisements for venues. When choosing a travel and hospitality destination, one of the things we often consider is the size of the crowd it pulls in, as large crowd often indicate positive attributes, including popularity, high quality, and a feeling of assurance. Now, due to the COVID-19 pandemic, avoiding crowded spots has risen several ranks on the priority lists of consumers. Fearing the risks of contracting the virus, people have been avoiding urban settings and popular tourist destinations. But is this trend universal? Does it apply to all kinds of travelers? Are there some tourist destinations or activities that travelers take part in regardless of the crowd?These are the few questions that this study by a team of researchers, including Associate Professor Jacob Chaeho Lee from Dongguk University, tries to answer in a new study published in Tourism Management.Based on the literature combined with empirical evidence from five survey-based experimental studies, the team hypothesized and demonstrated that, consumers under high salience of the COVID-19 pandemic display a diminished preference for crowded destinations. However, they also found that consumers who tend to seek sensation and have need for uniqueness show the opposite pattern. They also proved that this effect remains consistent across different travel and hospitality options regardless of the participants’ previous travel experiences. So, how does this study contribute to the recovery of the tourism and hospitality industry? Hailing these results, Dr. Lee says, “Our findings show that tourism and hospitality firms need to re-evaluate and reinvent their marketing strategies to adapt to this new consumer psychology and behavior. For example, firms may need to stop promoting the notion of crowding, popularity, or being trendy in the advertisements, social media, and review sites about their venues.” Their findings also suggest that during the pandemic, firms need to create new opportunities to attract consumers who tend to seek high levels of sensation and uniqueness in their consumption. The findings of the present study would greatly help tourism and hospitality firms to bounce back from the losses caused by the pandemic.

Dongguk University Study Reveals Factors Influencing Colorectal ...

Dongguk University Study Reveals Factors Influencing Colorectal Cancer in KoreaColorectal cancer has become a great healthcare burden in Korea. To find out why, scientists at Dongguk University in Korea examined the cancer caseloads against the distribution of dietary and lifestyle factors observed in the population. In a novel insight, they found that risk factors for this cancer differ by age and sex, suggesting that blanket prevention measures may not be sufficient for a healthier futureColorectal cancer (CRC) places an enormous burden on public health in South Korea. In 2018, the country had the second-highest number of CRC cases worldwide. While genetic factors are responsible for cancer, the risk factors for CRC have been strongly linked to certain dietary and lifestyle choices, such as smoking, increased alcohol consumption, low physical activity, and high processed meat intake. But that is global data. Does it apply to Korea specifically? A team led by Professor NaNa Keum from Dongguk University, Korea, has now decided to find out. In their study, they examined the trends in CRC incidence rates between 2001 and 2013, and compared them to the changing dietary and lifestyle behavior in the country during that time. “We aimed to identify major modifiable lifestyle factors underlying the alarming increase in CRC incidence in Korea specifically,” says Prof. Keum. The findings of the study were published in the Journal Scientific Reports on January 28, 2021.In their analysis, the researchers found an increase in the CRC caseload, with a higher prevalence in men compared to women. While most diagnosed cases were of late-onset CRC, there was a notable increase in early-onset cases among middle-aged adults (ages 30–49). Across all sex and age groups, decrease in exercise was a contributing factor for the increasing CRC trend. For men, obesity and increased alcohol consumption were observed to be major risk factors. For middle-aged women, there were significant increases in alcohol consumption, smoking, and processed meat consumption, likely contributing to the increase in early-onset cases. “Our findings do not prove the causal effects of risk factors on increasing CRC rates, but rather provide suggestive evidence that the risk factors differ by age and sex,” notes Prof. Keum.Speaking of the implications of these findings, Prof. Keum says, “Targeted public health interventions will be required to effectively reduce the CRC rate in Korea. A tailored approach, rather than generic lifestyle interventions, will help prioritize limited resources and induce greater compliance from people.”Hopefully, following on the footsteps of such studies, necessary measures can be taken to reduce the burden of CRC in Korea in the foreseeable future.

Dongguk University Researchers Design a Neuromorphic Device Rese...

Dongguk University Researchers Design a Neuromorphic Device Resembling Human BrainScientists at Dongguk University have designed a novel optoelectronic device with a dual function of memory storage as well as processing. In this Internet of Things (IoT) era, massive amounts of data are produced, collected, and transmitted through devices in real time. The separation of memory and data processing units adversely affects the smooth functioning of optoelectronic devices. South Korean scientists have now designed a predictable optoelectronic device—a multi-functioning “memtransistor”—to address these limitations.The current computing systems which have separate memory and processing devices cause excess energy consumption and slow down data transmission. Interestingly, even state-of-the-art 2D memtransistors—devices that can collect, store, and process information—exhibit sub-optimal electronic properties, such as unusually high operating voltages.To overcome these limitations, scientists at Dongguk University designed a predictable multi-functioning memtransistor. Their paper, which was made available online on November 5, 2021 and was published in Volume 5, Issue 12 of Small Methods on December 13, 2021, described how they fabricated a highly efficient optoelectronic and memory device using two-dimensional (2D) materials—nanomaterials that are merely one or two atoms thick—by stacking 2D tellurium flakes on a thin rhenium disulfide flake, followed by the deposition of an aluminum oxide layer.According to senior author, Dr. Hyunsik Im, who works as a Professor at Dongguk University, the team has developed an “Electrically and optically tunable p-n junction memtransistor fabricated with an Al2O3 encapsulated 2D Te/ReS2 van der Waals (vdW) heterostructure. This combines the favorable optical and electrical properties of p-type 2D Te and n-type ReS2 semiconductors, with a stable Al2O3 charge trapping layer.”In this optoelectronic memory device, multiple resistance states can be tuned by applying different voltages, or light powers. The transition between the high or low resistance states is controlled by carriers trapped in the Al2O3 layer under high electric fields. This causes an additional gate bias that tunes the Schottky barrier height at the ReS2/source electrode interface, while preserving p-n junction behaviors during the switching process, giving the device the added benefit of being electrically conductive, while being able to store memory efficiently.Quite remarkably, this novel device is material-independent and scalable. Moreover, it allows the integration of additional electronic circuits for neuromorphic computing—a set of processes that attempt to mimic the brain's architecture and data processing capabilities. “The development of these highly efficient memtransistor-based synaptic devices can decrease circuit complexity and minimize power consumption for neuromorphic computing and visual information processing. Mimicking synaptic activities in the human brain could become a much more manageable task in the near future,” says Prof. ImThe architecture of the human brain continues to inspire nanomaterial researchers.

Quantum Functional Semiconductor Research Center of Dongguk University, Development of quantum devices operating in room temperature- Successfully developed new-concept quantum devices capable of n-ary numeration digital logic- Published in ACS Nano, one of the best journals in the field of nanoscience and technologyDongguk University’s Quantum Functional Semiconductor Research Center (Director: Kim Deuk-Young) has developed a new-concept quantum device that enables logic of various multi-valued electronic information with one transistor. The center is a research institute that has been selected for the “University Priority Research Institute Support Project” by the Ministry of Education and is conducting the “Next-generation Quantum-Nano Structure Semiconductor Micro Information Device Research.”Lee Se-Joon, professor at the College of Physical and Semiconductor Science (corresponding author) and Dr. Lee Young-Min (principal author) of the Quantum Functional Semiconductor Research Center, who led the research, said that unlike the existing semiconductor quantum dot devices that operate only at very low temperatures, they have succeeded in manufacturing a quantum elliptical device that operates even at room temperature. In addition, by utilizing the spontaneous drive energy modulation function of the manufactured device, they have experimentally demonstrated that it is possible to selectively express and reconstruct various multi-valued electronic information using only one quantum device.The results show that not only can electronic information operations and logic circuits be reduced very simply, but existing CMOS device-based binary digital operations system can be switched to n-ary numeration systems. Professor Lee explains that expressing and calculating various multi-valued electronic information more quickly and easily can lead to developing n-ary numeration digital operation and information process systems more easily. This means that with even a very simple circuit configuration it is possible to quickly calculate and analyze a huge amount of information required for artificial intelligence, the Internet of Things, big data processing, and the like. He then expressed his hope that it could be actively used for applied research for portability, convenience, and versatility of ubiquitous devices in the future.Meanwhile, this research is groundbreaking and has not yet been reported worldwide, and is published in ACS Nano (IF = 15.881, JCR top 6.1%), one of the best journals in the field of nanoscience and technology.

A research team led by Professor Jae-Joon Lee from Dongguk University developed a highly efficient battery that operates under artificial indoor light.- Their research was selected as the cover article for Solar RRL, one of the most respected journals in the field of solar energy conversion- They developed the source technology of artificial light ALC that can be used as a source of energy for IoT devicesA study demonstrating a 63.4% increment in output power density for dye-sensitized photovoltaics (DSPV) with artificial indoor light, conducted by the research team led by Professor Jae-Joon Lee from the Department of Energy and Materials Engineering at Dongguk University, was selected as the cover article for Solar RRL, a prestigious journal that publishes high-quality research articles in the Wiley Online Library. Professor Jae-Joon Lee, who is the corresponding author, was accompanied by Dr. Ashok Kumar, Dr. Hyeong Cheol Kang, Dr. Francis Asiam, and Dr. Kicheon Yoo in synthesizing the nanophosphor SrF2:Pr3+-Yb3+ by codoping praseodymium (Pr, atomic number 59) and ytterbium (Yb, atomic number 70) with SrF2 and lanthanum nanoparticles for the first time. This nanophosphor was incorporated in the photoanode and used as an induction material for down-conversion. Dye-sensitized solar cell (DSSC), a next-generation solar cell, is gaining considerable traction as an alternative to the currently popular silicon solar cells due to its inexpensive materials, simple manufacturing process, and excellent performance (photoelectric conversion efficiency of 13%).Recently, there is a growing expectation for DSPVs that can be operated under indoor and artificial light conditions to open up a new path to energy self-sufficiency of wearables and portable smart electronics with its high performance and applicability. However, its low photoelectric conversion rate is a serious limitation as the photon harvesting performance of the DSPV's photoanode is rather poor due to low light intensity from artificial indoor light conditions. Therefore, the research team proposed to introduce SrF2:Pr3+-Yb3+, a nanophosphor that was synthesized for the first time, to the photoanode of the DSPV, and succeeded in increasing the output power density of the photoelectric cells to 63.4%. Thanks to this technique, it became possible to develop a source of energy for self-sustainable wearable devices, portable smart electronics, and IoT devices. Professor Jae-Joon Lee said, “As this technique showed a high level of efficiency not only for DSSC but also under artificial indoor light conditions, it can be used for indoor devices”. He optimistically added, “I hope that this study can be useful to other studies that seek to develop self-powered IoT devices.” This study was conducted with the support of Brain Pool programs (research on materials for photoelectric conversion-storage fusion devices operating on optimized light energy conversion) and Project for Climate Change Technology Development (development of organic-based solar cell source technology for urban distributed power generation) of the National Research Foundation of Korea.

For this special edition, Professor Paul Copp of the University of Chicago in the United States, who is recognized as a world-renowned scholar in East Asian language and civilization, and Professor Kim Yeon-mi of the Department of Art History at Ewha Womans University, who has been focusing on East Asian Buddhist art, participated as guest editors.Papers on various topics, in which leading researchers such as Ellen Gough of Emory University in the United States, Olivier de Bernon of The French School of the Far East, and Gergely Hidas of the British Museum participated, have been published. These are expected to contribute to a philosophical and historical consideration of Dhāraṇī, which was considered only as a religious and cultural asset.In addition to the special papers, research papers also included papers such as “An Account of Generous Action and Esteem in Pāli Buddhism” by Professor Nicholas Jones at Alabama State University in the United States and two in-depth reviews on the latest research results. The two reviews, which discuss recently published and remarkable Buddhist journals from a serious and open perspective, will also play a major role in navigating the current status of Buddhist studies.This will be an opportunity to expand the horizons of Buddhism and actively discuss directions for future research and international academic exchanges through the latest research achievements of world-class scholars representing each field and papers based on the same. The entire journal is available on the Academy of Buddhist Studies website.
