Maintaining active users who repeatedly share high-quality knowledge is critical for the success of online Q&A sites. This study suggests two paths that lead to active users' continuous knowledge sharing: 1) elaborated decision process, represented by continuance intention, and 2) automated cognitive process, represented by past behavior. The direct and moderating effects of continuance intention and past behavior were verified by analyzing subjective intention data and objective behavior data of 333 active users of Naver Knowledge-iN. Using Cox proportional hazards regression and negative binomial regression, the influences of continuance intention and past behavior on two types of continuous knowledge sharing were examined. The results showed that only past behavior was significantly influential on knowledge sharing continuance and as to the frequency of knowledge sharing, both continuance intention and past behavior's influences were significant. It was also confirmed that past behavior negatively moderates continuance intention's effect on the frequency of knowledge sharing. In order to maintain active users' continuous knowledge sharing, it is important to habituate knowledge sharing through repetitive knowledge sharing behavior. And in order to increase the frequency of knowledge sharing, in addition to the habituation, appropriate benefits that can increase the continuance intention should be provided.

Emotional labor may lead to service failure in service industries. Managers of an organization or a company can contribute to service recovery by reducing stress related to emotional labor. The aim of this study is to identify the antecedents and consequences of service recovery in respect of emotional labor. Data was surveyed from frontline employees to achieve the research purpose. The hypotheses were examined empirically using statistical tools. Results are as follows. First, surface acting had a negative impact on service recovery performance and deep acting had a positive impact. Second, empowerment and motivation had an influential relationship positively on service recovery performance. Third, service recovery performance was negatively related to intention to quit. In conclusion, managing employees' emotional labor strategies and work environment will bring high service recovery performance and low intention to quit.

As the online game industry has been growing rapidly, more and more malicious activities to gain economic benefits have been reported as well. Game bot is one of the biggest problems in the online game industry. So we proposed a bot detection method based on the ERG theory of motivation for the first time. Most of the previous studies focused on behavior-based detection by monitoring patterns of the specific actions. In this paper, we applied the motivation theory to analyze user behaviors on a real game dataset. The result shows that normal users in the game followed the ERG theory of motivation in the same way as it works in real world. But in the case of game bots, the theory could not be applied because the game bot has specific reasons, unlike normal game users. We applied the ERG theory to users to distinguish game bot users from normal users. We detected the game bot with high accuracy of 99.78% by applying the theory.

To support business decision making, interests and efforts to analyze and use transaction data in different perspectives are increasing. Such efforts are not only limited to customer management or marketing, but also used for monitoring and detecting fraud transactions. Fraud transactions are evolving into various patterns by taking advantage of information technology. To reflect the evolution of fraud transactions, there are many efforts on fraud detection methods and advanced application systems in order to improve the accuracy and ease of fraud detection. As a case of fraud detection, this study aims to provide effective fraud detection methods for auction exception agricultural products in the largest Korean agricultural wholesale market. Auction exception products policy exists to complement auction-based trades in agricultural wholesale market. That is, most trades on agricultural products are performed by auction; however, specific products are assigned as auction exception products when total volumes of products are relatively small, the number of wholesalers is small, or there are difficulties for wholesalers to purchase the products. However, auction exception products policy makes several problems on fairness and transparency of transaction, which requires help of fraud detection. In this study, to generate fraud detection rules, real huge agricultural products trade transaction data from 2008 to 2010 in the market are analyzed, which increase more than 1 million transactions and 1 billion US dollar in transaction volume. Agricultural transaction data has unique characteristics such as frequent changes in supply volumes and turbulent time-dependent changes in price. Since this was the first trial to identify fraud transactions in this domain, there was no training data set for supervised learning. So, fraud detection rules are generated using outlier detection approach. We assume that outlier transactions have more possibility of fraud transactions than normal transactions. The outlier transactions are identified to compare daily average unit price, weekly average unit price, and quarterly average unit price of product items. Also quarterly averages unit price of product items of the specific wholesalers are used to identify outlier transactions. The reliability of generated fraud detection rules are confirmed by domain experts. To determine whether a transaction is fraudulent or not, normal distribution and normalized Z-value concept are applied. That is, a unit price of a transaction is transformed to Z-value to calculate the occurrence probability when we approximate the distribution of unit prices to normal distribution. The modified Z-value of the unit price in the transaction is used rather than using the original Z-value of it. The reason is that in the case of auction exception agricultural products, Z-values are influenced by outlier fraud transactions themselves because the number of wholesalers is small. The modified Z-values are called Self-Eliminated Z-scores because they are calculated excluding the unit price of the specific transaction which is subject to check whether it is fraud transaction or not. To show the usefulness of the proposed approach, a prototype of fraud transaction detection system is developed using Delphi. The system consists of five main menus and related submenus. First functionalities of the system is to import transaction databases. Next important functions are to set up fraud detection parameters. By changing fraud detection parameters, system users can control the number of potential fraud transactions. Execution functions provide fraud detection results which are found based on fraud detection parameters. The potential fraud transactions can be viewed on screen or exported as files. The study is an initial trial to identify fraud transactions in Auction Exception Agricultural Products. There are still many remained research topics of the issue. First, the scope of analysis data was limited due to the availability of data. It is necessary to include more data on transactions, wholesalers, and producers to detect fraud transactions more accurately. Next, we need to extend the scope of fraud transaction detection to fishery products. Also there are many possibilities to apply different data mining techniques for fraud detection. For example, time series approach is a potential technique to apply the problem. Even though outlier transactions are detected based on unit prices of transactions, however it is possible to derive fraud detection rules based on transaction volumes.

Sports events are not copyrighted and sports organizer's profit from sports events is not subject to intellectual property law in our legislation. Most other countries, except for France, do not also recognize sports organizer's profit as an intellectual property right. For this reason, legal grounds protecting sports organizer's profit must be found from current law such as tort law or Unfair Competition and Trade Secret Protection Act. It is irrefutable that these laws play a significant role in protecting sports organizer's profit by imposing restrictions on taking unfair advantage of others' efforts or investment. Nevertheless, protecting sports organizer's profit through such laws has its limits because sports events and relevant information outside the protection category of intellectual property law are considered as public domain. Therefore, introduction of sports organizer's intellectual property right through legislation will serve to faithfully protect sports organizer's profit. Even countries where spectator sports industry is fully in force actively discuss the issue of introducing sports organizer's intellectual property right. Intellectual property law, like other laws, is keenly subject to international trends due to market globalization and sensitively responds to the trends. I believe that further discussions are highly required about the introduction of sports organizer's intellectual property right that properly reflects international trends.

일반적으로 성리학에서는 개인의 이익보다 도덕적 선택을 우선하라고 요구한다. 그러나 "주역"에서는 결코 이익을 죄악시 하지 않는다. 이 글은 성리학자이면서 역학자인 주자의 이익과 도덕에 대한 입장을 추적하는 연구이다. 주자가 소옹의 결정론적 세계관과 도덕적 자유의지를 강조하는 이천의 관점을 결합함으로써 완성하고자 한 것은 "주역"의 서(筮) 속에서 리(理)를 확인할 수 있다는 것이었다. 점서(占筮)의 결과가 그렇게 나오는 것은 그에 해당하는 이치가 있기 때문이라는 말이다. 그런데 "주역"의 리(理) 즉 역리(易理)란 오랜 경험과 관찰을 통해 확보된 사회적 존재로서 인간의 심리적 행위적 경향성의 총합이다. 그리고 그 구체적인 내용은 바로 상황적 합리성과 타자와의 조화로움이다. 이 리(理)는 우주와 사회의 정해진 질서로서 우리에게 주어진다. 개인은 이 주어진 질서에 따를 수 있는 자유와 함께 따르지 않을 수 있는 자유를 지닌다. 때문에 정해진 질서와 그 속에서의 개인의 자유의지는 양립가능한 것으로 받아들여지고, 그런 의미에서 주자는 약한 결정론자라고 할 수 있다. 성리학은 우주의 질서로부터 부여받은 당위의 법칙에 자발적으로 동의할 것을 요구한다. 그것이 가장 올바른 선택이면서 동시에 자신에게 가장 이로운 선택이기 때문이다. 주자는 상황적 합리성과 타자와의 조화로운 관계에서만이 자신의 진정한 이익을 추구할 수 있다고 생각한다. 타자와의 유기적 관계를 부정하고 유아적(唯我的) 이익만 추구하려는 자는, 사회적 존재로서 인간이 지니는 심리적 행위적 경향성을 무시한 어리석은 자이다. 이렇게 주자에게서 이익[리(利)]은 상황적 합리성[의(宜)]이 되고 또 그것은 바로 도덕[의(義)]이 된다. 참다운 의미에서의 합리적인 판단은 도덕적 선택을 불러온다.

Organizational humor is generally perceived as a phenomenon that helps to develop happy feelings and positive workspace. While humor may affect organizational members in diverse ways, the ambiguous nature of humor may create uncertainty and unexpected outcomes. In particular, humor used by and between organizational members in diverse organizational situations (including physical office context and work hours) may influence individual's perception of space. Findings suggest that humor interaction acts as a form of deviant behavior that diverts from work. This momentary non-work event (humor) may serve as a ritual to influence individual's perception of space, from work to personal domain, and vice versa. The quality of interpersonal relationships between the communicators may also be influenced by humor. This shift in the nature of interaction (from work to non-work) may lead to blurring boundaries of work and work experiences. Therefore, organizational humor may provide insights into how workers interact, perceive, and manage work and personal space within organizational contexts.

The Government R&D budget for 2019 exceeded 20 trillion won in order to develop future growth market such as basic research investment and creation of growth engine. As such, the importance of R&D investment is increasing, and various schemes for enforcing efficient and transparent business expenses are being expanded. However, research expenses (Charge ratio) such as fraudulent execution of funds are continuously being generated, and a system of imposition of sanctions is being introduced. In this paper, the legal grounds of sanctions, comparative review of laws and regulations between the ministries, and the criteria of imposition (imputation) were analyzed. In addition, since the amendment of the standard for imposing the intergovernmental surcharges, a single standard has been applied, and the transition process of the surcharging system has been reviewed. As a result of the data analysis, it was found that they focused on micro - utility activities and suggested new policy measures corresponding to them.

The purpose of this study is to investigate the effects of awareness of oral health on oral health status and oral health behavior with subjects of students in the middle school which is the important period when lifetime set of teeth is completed with eruption of the second molar tooth and complete set of permanent teeth, and provide the basic data for development of oral health program for adolescents. We examined oral condition and conducted the survey about students' awareness of oral health and behavior in the middle school located in JeonJu. As the results of oral examination, dental caries and malocclusion were higher in female students and periodontal disease was higher in male students (p < 0.038). There was no significant difference in awareness of oral health between male and female students. However, M = 4.08 out of 5 point scale, which was high. For oral health behaviors, female students (M = 4.508) was higher than male students (M = 4.257) in the question of 'I visit the dental office when my gums are bleeding'. Female students (M = 4.547) was higher than male students (M = 4.333) in the question of 'I use the dental floss after brushing my teeth'(p<0.05). Awareness of oral health gave the significant effect on the oral health behavior at 95 % confidence level. Therefore, the education for oral health behavior is required to improve oral health and studies are needed to present the development of program for awareness and knowledge of oral health affecting behavior.
