  • School adjustment has been a popular topic among scholars in multicultural family studies, and they commonly report poor adjustment of children from multicultural families. However, without subjects for comparison, these findings may be considered premature. This study investigated school adjustment of children from multicultural families by comparing their adjustment level to that of children from families with Korean parents. By using the matching procedure, this study examined whether children's multicultural family background attributes to their school adjustment with children's observable characteristics paired and matched. For the analyses, the first and fourth wave of Korean Children and Youth Panel Study data were used. When the school adjustment level was examined before the matching procedure, the school adjustment level was indeed lower among children of multicultural families, and their family status was a significant predictor of school adjustment. However, when two groups were paired and matched using matching, the family background had no significant effect, indicating that school adjustment is not predicted by their multicultural family status. Implications for research and practice are also discussed in the paper.

  • Early detection of oestrus in Korean cows is one of the important issues in maximizing the economic benefit. Although various methods have been proposed, we still need to improve the performance of the oestrus detection system. In this paper, we propose a video surveillance system which can detect unusual behavior of multiple cows including the mounting activity. The unusual behavior detection is to detect the dangerous or abnormal situations of cows in video coming in real time from a surveillance camera promptly and correctly. The prototype system for unusual behavior detection gets an input video from a fixed location camera, and uses the motion vector to represent the motion information of cows in video, and finally selects a SVDD (one of the most well-known types of one-class SVM) as a detector by reinterpreting the unusual behavior into an one class decision problem from the practical points of view. The experimental results with the videos obtained from a farm located in Jinju illustrate the efficiency of the proposed method.

  • This study examined the mediation effects of covert narcissism on the relationship between game addiction and aggression. For this study, 578 middle school boys in Chungcheong areas were included in the analysis. The results are as follows. First, correlation analyses showed that game addiction was positively correlated with covert narcissism and aggression. In addition, covert narcissism showed positive correlation with aggression. Second, step-wise regression analyses were conducted to examine the relative size that sub-factors of game addiction and covert narcissism explained aggression. It could be known that three factors of game addiction(tolerance, disregard of everyday life, damage of control) and two factors of covert narcissism(exploitation/self-centeredness, oversensitivity/vulnerability) showed significant explanatory power for aggression. Third, the Structural Equation Model was designed in which factors of game addiction and covert narcissism with significant explanatory power for aggression were included. Covert narcissism was found to partially mediate the influence of the boys' game addiction on aggression. Finally implications of this study and directions for future research were discussed.

  • This study analyzed data from 1997 Korea's Behavioral Risk Factor Surveillance System Survey collected through telephone questionings based on the multi-stage stratified random sampling. We categorized respondents into those who had ever drunk an alcoholic beverage in the last month and those who didn't and, referring to the World Health Organization's guideline, the former group were further categorized into low risk drinking group and high risk drinking group. Employing bivariate probit regression analyses with censoring on independent variables such as preferred type of alcoholic beverage, the number of types of beverages consumed, age, marital status, education, occupation, residential area, current smoking, body mass index and stress suggested (1) that those who prefer soju are more likely to involve high risk drinking than those who and prefer the other alcoholic beverages (2) that those who are relatively older, who live without a partner, who have jobs, who. are vulnerable to stress, or who enjoy more than one type of beverage are more likely to be exposed to high risk drinking than the others.

  • The purpose of this research is to present the implication for Korean firms' entry into the power market in Myanmar. This study investigated the characteristics of the Myanmar power market and analyzed SWOT, focusing on energy policy, power supply and demand, energy relations with neighboring countries and climate change issue. Opportunity factors are changes in energy strategies, the launch of an energy integration organization, changes in the power energy portfolio, rapid economic and power demand growth, and a clean development mechanism. The threats are high nonfulfillment of a contract, high power loss rates and low electricity distribution rates, increased energy exports to neighboring countries, and vulnerability to climate change. We suggest the use of CHP (Combined Heat and Power), Clean Development Mechanism (CDM), and Multilateral Development Bank (MDB).

  • One of the current issues in Workers' Compensation Insurance is about the coverage range. Korea uses the definition of worker under the Labor Standards Act in Workers' Compensation Act and solved the problems associated with the coverage range of insurance group by the exceptional clause only for the groups which was raised about the need for the social protection. The purpose of this paper is to draw implications for solving problems which are associated with the coverage range of insurance group by reviewing the German literature. We focus on volunteers and persons in special types of employment. German government supports the activity of volunteers by providing with the protection service against the accidents. This paper shows how the coverage range is extended from the dependent employees in the introduction of the Workers' Compensation Insurance to the people who need social protection focusing on the volunteers. The implications of this research are following. First, German system shows that Workers' Compensation Insurance can be extended to the groups which do not belong to the dependent employee but are worthy of protection. Second, it is necessary to provide volunteers in the social welfare system with the protection service against the accidents and the statutory accident scheme is recommendable to use. Third, volunteers in the social welfare system need to be compulsory insured. Fourth, Korea should find their own way in solving problems associated with persons in special types of employment.

  • Concerning the risk factors of the outbreak of a fire in a traditional market, most of those markets are located in downtown areas or residential areas; thus, although their location may be favorable in terms of marketability, they face a potential risk in that a fire may develop into a large blaze owing to poor environment or the absence of facilities prepared for disaster during a fire. Moreover, as many people are densely poised in the markets, it is very probable that a fire may occur owing to the excessive use of heaters in the winter as well as the reckless use of electric and gas facilities. It seems that traditional markets encounter difficulty being insured against fire, because of their vulnerability and that the vast majority of small-scale sellers are likely to suffer mental anguish and tremendous physical injury in case of a fire. However, most of those sellers in the traditional markets are hand-to-mouth sellers, and they lack awareness of safety concerns and have insufficient experience in safe facility management. As small-scale sellers constitute the majority in the traditional market, the subscription rate of fire insurance in most of the traditional markets is low for the reasons of their needy circumstances and their financial burden. Statistically, the subscription by street vendors is non-existent; therefore, these vendors have a fairly limited access to indemnification after fire damage. Because of these problems, this study's purpose is to identify the current level of insurance subscription by these markets, which are exposed to poor facilities and vulnerability to fire. In order to fix this, it appears that shop owners and consumers will have to band together. For this study, we executed a fire policyholder fact-finding mission at traditional markets with approximately 108 and 981 stores. The research method was executed by an investigation using one-on-one individual interviews using a questionnaire. The contents investigated current insurance subscriptions. The method of analysis looked at the difference of insured amount according to volume size through cross-tabulation of the difference of insured amount by possession form, difference of insured amount by market form, difference of insured amount by category of business, difference of insured amount by market size, etc. Furthermore, the study should be used to propose solutions for problems through theoretical review with the use of a literature research, because the field case study was through interviews with the persons concerned, and the survey of the current insurance subscriptions by traditional market shopkeepers. The traditional market would generally have difficulty affording fire insurance. Fire insurance subscription rates of most of the market proved to be inactive, because of the economic burden of payment. Lack of funds is thought to be the main factor that causes a lack of realization about the necessity of fire insurance. In addition to expensive insurance premiums, sometimes, the companies' valuation of the businesses is lower than their actual valuations, and they do not pay out enough during a claim. The research presents an improvement plan that, when presented at the traditional markets, may strengthen their ability to procure fire insurance through the help of the central government. Researchers connected with the traditional market mainly accomplish the initial research. However, although this research has its limitations, it offers considerable benefits. For future researchers, I would suggest looking at several regions for comparison.

  • The Internet of Things (IoT), which is emerging as a future economic growth engine, has been actively introduced in areas close to our daily lives. However, there are still IoT security threats that need to be resolved. In particular, with the spread of smart homes and smart cities, an explosive amount of closed-circuit televisions (CCTVs) have been installed. The Internet protocol (IP) information and even port numbers assigned to CCTVs are open to the public via search engines of web portals or on social media platforms, such as Facebook and Twitter; even with simple tools these pieces of information can be easily hacked. For this reason, a big-data analytics system is needed, capable of supporting quick responses against data, that can potentially contain risk factors to security or illegal websites that may cause social problems, by assisting in analyzing data collected by search engines and social media platforms, frequently utilized by Internet users, as well as data on illegal websites.

  • PVC (polyvinyl chloride) intravenous fluid bags and tubes that contain DEHP (diethylhexyl phthalate) as a plasticizer have several associated disadvantages for intravenous injections. We investigated the drug absorption behaviors on the inner surface of an infusion tube that consisted of commercialized PVC/PU (polyurethane). We developed a non-PVC (polyolefin) tube in order to improve the efficacy of this drug administration method. We prepared four types of non-PVC (polyolefin) infusion tubes using a polyethylene (PE), polypropylene (PP), syndiotactic 1,2-polybutadiene (PB), and styrene-ethylene (SE) copolymer elastomers were prepared using a single screw extruder. The four types of manufactured non-PVC (polyolefin) infusion tubes had good mechanical properties that were equivalent to PVC tube properties. The four types of prepared non-PVC (polyolefin) infusion tubes also prohibited drug absorption when compared to the commercialized PVC and PU tubes. Therefore, based on the results of this study, prepared non-PVC (polyolefin) tubes are good candidates for infusion because they prevent drug absorption and the release of DEHP.

  • Recently, security behavior of members of organizations has been recognized as a critical part of information security at the corporate level. Leakage of customers' information brings more attention to information security behavior of organizations and the importance of a task force. Research on information breach and information security is actively conducted of personal behavior toward security threats or members of organizations who use security technology. This study aims to identify factors of influence on information security behavior of members of organizations and to empirically find out how these factors affect information security behavior through behavior toward attitude, subjective norm and perceived behavior control. On the basis of the research, this study will present effective and efficient ways to foster information security activities of members of organizations. To this end, the study presented a research model that applied significant variables based on integration of Theory of Planned Behavior (TPB) and Theory of Protection Motivation (TPM). To empirically verify this research model, the study conducted a survey of members of organizations who had security-related work experience at companies. So, it is critical for members of organizations to encourage positive word of mouth (WOM) about information security behavior. Results show that based on the integration of TPM and TPB, perceived vulnerability, perceived severity, perceived efficiency and perceived barriers of information security behavior of members of organizations had significant influences on mediating variables such as behavior toward attitude, subjective norm, perceived behavior control and intention. They also had significant influences on organization information security behavior which is a dependent variable. This study indicates companies should introduce various security solutions so that members of the organizations can prevent and respond to potential internal and external security risks. In addition, they will have to take actions to inspect vulnerability of information system and to meet security requirements such as security patches.
