This paper quantitatively analyzes the current status of North Korean consumer payment instruments through a questionnaire survey of 292 North Korean defectors. In the 2010s, it was found that the payment experience ratio of domestic currency cash and grain decreased, while the payment experience ratio of foreign currency cash increased. The use of foreign currency reached a stage where it was spread not only as a store of value but also as a medium of exchange. However, the most frequently used payment instrument by North Korean consumers was still domestic currency cash. By region, in inland urban areas both domestic currency cash and U.S. dollars are used and in the North Korea-China border region both domestic currency cash and Chinese yuan are used, while in inland rural areas dollarization does not occur because both domestic currency cash and grain are used. Meanwhile, despite the stable price trend during 2013-2019, the dollarization hysteresis effect is appearing, and both the purchasing power risk theory and the network externality theory are considered to have explanatory power for the cause. The results of this paper suggest that as dollarization is intensifying, it is expected that more costs such as shortages of commodities will be incurred than in the past if North Korea's de-dollarization policy is reimplemented. Also, in the case of domestic currency cards, which the North Korean authorities introduced in 2015 as part of a means of financial reform, this paper suggests that it may continue to be difficult for domestic currency cards to normalize official finance under the dollarization hysteresis.

The purpose of this study is to analyze service quality factors that consumers perceive during their purchasing product on Internet Shopping Mall. The study defines the characteristic quality dimensions of Internet Shopping Mall by adding three dimensions consisting of convenience, security and entertainment to PZB's SERVQUAL scale. Consumers' purchase process on Internet Shopping Mall is examined by finding the relation between their perceived risk factor and repurchase intention. The study results show that consumers' higher appraisal degree on service quality means their higher repurchase intentions, their lower perceived risks degree. The repurchase intentions and the perceived risks degree have negative correlation. The more consumers have experienced buying on Internet Shopping Mall, the higher consumer assess service quality, they have higher repurchase intention and lower perceived risk. The most basic contribution is that new service quality dimensions, which is able to clarify service quality on Cyber Mall, is identified with the established PZB(I988; 1991)'s SERVQUAL dimensions.

The goal of this study was to investigate risk factors associated with porcine reproductive and respiratory syndrome (PRRS) in pig farms in the Republic of Korea using logistic regression and a multilevel model. A cross-sectional study was applied to 305 pig farms with a questionnaire-based interview by veterinarians between March 2014 and February 2015. The questionnaire comprised eight categories: proximity to neighbors, disinfection, visitors, vehicles, insecticides, wild animals, gilts, and feeding. In total, 61 questions in eight categories related to pig farm biosecurity were investigated. Farms were classified as PRRS stable or unstable based on the results of an antibody test and PCR. For univariate analysis, keeping production records with computers (OR = 0.283, 95% CI = 0.056 - 1.425), accredited farm with no use of antibiotics (OR = 0.412, 95% CI = 0.134 - 1.269), reviewing health record of semen prior to purchasing (OR = 0.492, 95% CI = 0.152 - 1.589), complete isolation of runt pigs (OR = 0.264, 95% CI = 0.084 - 0.829), compulsory registering for visitors (OR = 0.424, 95% CI = 0.111 - 1.612), keeping records of insecticide history (OR = 0.406, 95% CI = 0.089 - 1.846), routine on-farm monitoring by veterinarians (OR = 0.314, 95% CI = 0.069 - 1.423), and use of on-farm checklist for biosecurity monitoring (OR = 0.313, 95% CI = 0.063 - 1.553) were found to decrease the probability of PRRS infection. Multivariate and multilevel analysis revealed only two factors, complete isolation of runt pigs (OR = 0.165, 95% CI = 0.045 - 0.602 and OR = 0.208, 95% CI = 0.055 - 0.782) and compulsory registering for visitors (OR = 0.106, 95% CI = 0.017 - 0.655 and OR = 0.119, 95% CI = 0.017 - 0.809) were found to decrease the probability of PRRS infection. The intracluster correlation coefficient of a province for multilevel model was 0.05. The results of this study might facilitate biosecurity measures for individual farms to reduce the probability of PRRS infection.

IS outsourcing has an important meaning to the Korean SME's (Small and Medium Enterprises) which want to use the IS Services. The objective of this research is to manage IT risks occurred during IS outsourcing project process. This study tries to identify these risks using real option methodology. In order to perform this objective, this study set up the research model which is composed of two main concepts. The first one is the risk factors occurred during IS outsourcing project process: User's Risks, Supplier's Risks and Transaction's Risks. All of these risks are based on Transaction Cost Theory. The second one is the intention to get (or buy) Real Options to manage the risks. In the research model, two types of real option are included: option to abandon (put option) and option to defer (call option). This study uses questionnaires and statistics methodology (PLS) to analyze the hypotheses proposed in the research model. Compared with prior studies, this study is different in two ways. First, this study restricts the range of IT risks. Prior researches of IT Risk management in MIS area cover various range of IT risks, but this study focuses on the Korean SME's IT outsourcing risks on the basis of Transaction Cost Theory. This study tests the relationship between the risks and real option types. Second, this study tries to test the moderating effect of user's risks and supplier's risks on the relationship between transaction's risks and real option types. In IT outsourcing research area, almost studies focus on the direct relationships between IT risks and outsourcing success. But in reality, the co-relationship among IT risks may occur. There are some findings according to the research analysis. First, risks related with user's risks have strong causal relationships with the intention to get option to abandon (put) and option to defer. But risks related with supplier's risks have causal relationships only with option to abandon (put). Second, user's risks and supplier's risks have no moderating effect on the relationship between transaction's risks and real option types. According to the research results, this research have some important and interesting implications on the IS outsourcing business area. First, this study identifies the effective types of real option to minimize the risks occurred during the IT outsourcing projects. So IS outsourcing service users can manage (or minimize) effectively the risks, which occurred during outsourcing projects, using real options. Second, real option gives benefits to suppliers and users at the same time (i.e., win-win strategies between IS outsourcing service providers and users). Vendors (:IS outsourcing service providers) can offer users the real options which can minimize the occurrence of risks in time. "IN TIME" means that before the IS outsourcing project starts, vendors can offer users the opportunity to buy real options in appropriate prices to manage the possibility of the risks of IS outsourcing project. And users also have chance to minimize the IT outsourcing risks occurred during the project process using real options.

Natural stream disasters due to a localized torrential and flash flood has occurring in a small stream especially un-implemented small stream. The survey results during ten years from 2001 to 2010 show that the small stream implementation projects (SSIPs) expenses is increasing with the damages is generally decreasing with variableness in which SSIPs is contributing to disaster prevention in a small stream. This study develop guideline for the selection of SSIPs to support high risk stream at first and save the small streams located on the mountainous area, prevention area and agricultural area which streams have no implementation effects. Developed sub items in guideline are evaluated by stream data collected from 212 small streams where it is proved that sub distance of each item are well arranged by normal distribution. This SSIPs is useful for selecting high risk small stream at first to maximize disaster risk reduction with minimum SSIPs expenses. Also, this SSIPs is used for leading to save small stream on the upstream to minimize flood damages on the down stream with selection a SSIP purchasing agricultural land for preparing flood plane.

This study intends to examine how the perception of covid-19 risk affects consumers' consumption behavior based on previous studies in a situation where the spread of covid-19 is prolonged. This study demonstrates how consumers' perception of covid-19 risk affects online and offline consumption behavior through the perceived severity, perceived vulnerability, coping effectiveness, and self-efficacy of the revised protective motivation theory (Rogers, 1983). We want to test it through analysis. In order to achieve the purpose of this study, consumers living in Seoul and Gyeonggi Province who have purchased within the past 3 months were selected as a sample. In addition, variable data such as risk perception of covid-19, perceived severity, perceived vulnerability, coping effectiveness, self-efficacy, online purchase attitude and purchase intention, offline purchase attitude and purchase intention were collected through the questionnaire.A total of 363 copies of valid responses were tested to test the hypothesis of the relationship between variables through the covariance structure model. The analysis results of this study were first, that covid-19 risk perception had a significant positive (+) effect on perceived severity, perceived vulnerability, and coping effectiveness. Second, perceived severity and perceived vulnerability were found to have a significant positive (+) effect on offline purchasing attitude. Third, perceived severity, perceived vulnerability, coping plan effectiveness, and self-efficacy were all found to have significant positive (+) effects on online purchase attitude. Finally, it was found that offline purchase attitude and online purchase attitude had a significant positive (+) effect on offline purchase intention and online purchase intention, respectively. Also, it was found that online purchase attitude had a negative (-) effect on offline purchase intention. The results of this analysis will provide meaningful implications for the establishment of strategies for distribution channels according to the social risk of infectious diseases.

It is a general trend in the world that female workers are drastically increasing due to the facts that highly developed capitalism requires women's job, women are inspired to work, housewives can shorten their working hours for house-keeping and save their energy from their routine works, educational expenses of their children become larger, large among of modities has stimulated purchasing desire. Since the International Treaty on Prohibition of Female's Night Labor was agreed at the Bern's Conference in 1906, the International Labor Organization (I.L.O.) established after the World War II, has adopted innumerable international labor treaties. According to the laws of the advanced countries, the first priority of their protection has been placed on juvenile and female workers. The legal protection of female workers and equal treatments such as wage and promotion between men and women have become important world problems. In this thesis, the great principle of the Labor Standard Law, protection regarding working house, risk and harm in performance of jobs, protection of mother-workers, protection of women workers in advanced countries and the present status of welfare facilities for women workers in our country will be studied. The most important points this thesis has placed stress and appealed, are as follows : 1. The scope and variety of women workers' jobs should be broadened. 2. Opportunity for promotion should be guaranteed for women workers based upon the ability and capacity of individual woman worker. 3. Equal wage principle between men and women workers, should be established based upon the idea that men and women should be equal. 4. The age limit or marriage limit of employment applied only to female workers, should be abrogated. 5. The ability of middle and old aged women workers should be developed and utilized to the maximum extent. 6. Welfare facilities for women workers, should be urgently secured and guaranteed.
