It is recognized that one of the major issues in jail management is responding to the needs of a growing number of inmates with mental health problems. The purpose of this study was to assess the nature and severity of mental health problems among inmate population. The mental health status of 1,500 (1,337 responded) inmates of the 30 prisons located in nationwide area was examined using Minnesota Multiphasic Personality Inventory (MMPI). And the scores on MMPI were examined in relation to some offender characteristics such as type of offence, treatment classification, frequence of discipline. The result indicates that the percentage of inmate population with scores over 70 on every sub-categories of the scale is higher than that of general populations reflecting high rate of deviation from average normal mental health. It seems likely that many of inmates are in need of specific mental health treatment services. The nature and severity of mental health problems varies depending on offender characteristics above mentioned. It is also notable that the inmates are heterogeneous in terms of mental health status, and that severe offences such as robbery, assault, and rape or sexual assault are highly related to the scores on 'antisocial' sub category. The study also reveals that there is a relation, if not causal, between mental health problem and frequency of discipline while in prison. Under basis of these findings, this study concludes that a number of inmates in our prison have mental health problems requiring mental health treatment services and suggests five key steps to effectively respond to the prevalence of mental health problems in prison at both the level of the clinical interventions and at the level of system structure and organization. Specially, the importance of collaborative service strategies of the correctional system with mental health systems are underlined.

RFID는 RF신호를 이용하여 물체를 식별하는 가장 유망한 미래의 비접촉 기술이다. RFID 리더의 식별영역에 여러 개의 태그가 있는 경우, 리더의 질의에 대하여 모든 태그들이 동시에 응답을 하기 때문에 충돌이 발생되어 태그를 식별할 수 없게 된다. RFID에서 다중 태그 식별문제는 아주 중요한 핵심 기술로 이것을 해결하기 위해 슬롯기반 알로하 알고리즘, 트리 기반 알고리즘 등과 같은 충돌 방지 알고리즘이 제안되었다. 본 논문에서는 RFID 시스템에서 충돌 트리를 이용한 충돌트리 기반 충돌 방지알고리즘을 제안한다. 제안하는 방법은 효과적인 충돌 방지 메커니즘을 제공하며 메모리래스 알고리즘이다. 제안하는 충돌트리는 다중 태그 식별문제를 해결하기 위한 메커니즘으로 리더와 태그사이 질의와 응답과정에서 만들어진다. 리더가 k 비트로 구성된 프리픽스를 질의하면, 태그는 자신의 식별자와 프리픽스를 비교 하여 일치할 경우 식별자의 K+1 비트에서 마지막 비트까지 리더에게 전송한다. 시뮬레이션 결과에 따라 제안하는 충돌 트리 기반 충돌 방지 알고리즘이 기존의 트리 워킹 알고리즘이나 쿼리 트리 알고리즘보다 좋은 성능을 보임을 알 수 있다.

Entering into the new millennium, the Korean wine market has recorded the highest growth rate among the domestic alcoholic beverage market and been recognized as a rapidly emerging market with further escalation potential. Responding to the current drastic escalation of Korean wine market in terms of its volume, the present study scrutinizes the considerable wine-selection attributes that are related to individual wine consumer‘s characteristics including demographic variables. These attributes are also expected to be precursors of wine consumers‘ satisfaction. ANOVA results suggest that each demographical variable-gender, age, income level, and the frequency of wine consumption-pertains to specific wine-selection attribute(s). Likewise, wine consumers‘ characteristics are also associated with those attributes. As wine consumers are experienced, they rely less on information; rather, their selections tend to be dependent upon quality, value, contexts, and preferences. The subsequent multiple-regression investigating the relationship between wine-selection attributes and satisfaction signifies that quality, contexts, and preference attributes are the substantial antecedents of wine consumers‘ satisfaction. When consumers purchase a wine, "information on purchase" was the most important criterion for the Newcomers and the Outsiders, while the Connoisseurs mainly depended on "marketability", "wine values" and "viticulture environment". "Preference" attributes influenced the Aspirants the most in buying decision. The Newcomers and the Outsiders need more information before deciding to purchase as their wine knowledge was very limited. The Connoisseurs were likely to consider the quality as a more important factor than the price and it is necessary to develop high quality wine at a reasonable price in order to attract this group.

The purpose of this study was to examine the dynamics of psychological and sexual violence in dating among high school students. Subjects consisted of 1,205 male and female adolescents from all parts of the country. 1,092 respondents were included in the final analysis(90.6%). For psychological violence, 13.3%(n=145) reported to have such experiences with a dating partner at least once or more. The most frequently used forms of violence were shouting, insulting language and behaviors, and blaming for a physical appearance. There were no sex differences in frequency of psychological violence between males and females, as an aggressor or a victim. Responses of victims were mostly negotiation and communication, and trying to forget it. For sexual violence, 27.8%(n=303) was found to have such experiences in a dating scence at least once or more. Hugging and kissing, close contact of parts of body, and gazing at parts of body were most frequently used forms. Responses of victims were pretending not to notice it and responding in the same way. There were significantly more male aggressors of sexual violence than females, but no sex difference in the number of victims. Those who reported to have experiences of violence were compared to the counterparts who had no experience in attitudes toward violence between dating partners and married couples, experiences of violence in childhood, school violence, and observations of violence between parents. Those with experience of dating violence reported to have significantly more experiences of violence in childhood and school, and parental violence. Based on the findings of this study, suggestion were made in regard to the need for development of dating violence prevention program for adolescents, and for welfare programs for adolescents in community.

This study conducted a quantitative assessment on the environmental flows associated with climate change in the Gosam Reservoir, Korea. The application of RCP 8.5 climate change scenario has found that the peak value of High Flow Pulses has increased by 36.0 % on average compared to historical data (2001 ~ 2010), which is likely to cause disadvantage on flood control and management but the increase in peak value is expected to make a positive impact on resolving the issue of green algal blooms, promoting vegetation in surrounding areas and encouraging spawning and providing habitats for native species by releasing a larger amount of landslides as well as organic matters than the past. However, the decreasing pattern of the peak value of High Flow Pulses is quite apparent with the trend of delay on the occurrence time of peak value, necessitating a long-term impact analysis. The peak value of Large Floods shows a clear sign of decrease against climate change scenario, which is expected to lead to changes in fish species caused by degraded quality of water and decreasing habitats. A quicker occurrence of Small Floods is also expected to make an impact on the growth cycle of aquatic plants, and the reduction in occurrence frequency of Extreme Low Flows is to contribute to increasing the population of and raising the survival rate of native fish, greatly improving the aquatic ecosystem. The results of this study are expected to be useful to establish the water environment and ecological system in adapting or responding to climate change.

Our nation has experienced remarkable growth over the half a century. Nonetheless, there is still much room for improvement in the area of Environment, Health and Safety (EHS). In particular, frequency and severity of industrial accidents did not considerably improve compared to the economic and social progress we made. The main objective of this research is to analyze what plans and actions are required for companies to promote industrial safety by 1) fostering functional competencies of EHS staffs and 2) effectively and proactively responding to rapidly changing EHS environment. For this research, EHS staffs from five large companies in Korea were surveyed. Most respondents indicated that one of key expertise required by EHS staffs is capabilities to effectively deal with changes to various domestic and international EHS-related laws and regulations. Furthermore, a predominant number of respondents commented that it is imperative for EHS staffs to have a broad knowledge of business management. As for internal issues that EHS staffs encounter within their organizations, many pointed out that their EHS vision is not sufficiently shared throughout the organization, and that the rules of leadership are critical in solving this issue. On the other hand, the survey respondents also raised an issue of limited EHS-related investments due to slow economy. As a solution, they proposed ways to align EHS organization's performance with the company's performance. Based on this survey, issues and solutions for EHS organizations were identified. Results of this research can benefit companies that plan to newly establish or further expand EHS organization.
