Korea's police force has successfully performed its difficult mission of maintaining public order while overcoming difficulties at home and abroad during the past half century. However, the environment in which the forces of law a nd order operate has exponentially increased the demand for, and difficulties faced by, the agents of law enforcement in recent years because of the country's rapid globalization, as well as the move to democracy and localization, and the extensive developments in industrialization and information technology diffusion. This study also intends to investigate the appropriate limits of law enforcement and the use of force by policemen, and the general public's perception of the police as they fulfill their duty of protecting citizens' rights.

R&D에 관한 주요 국가 및 산업기술의 정보 유출이 문제가 되고 있다. 2009년 11월 국가과학기술지식정보서비스(NTIS)는 영국표준협회(BSI)로부터 ISO 27001에 대한 11개 도메인, 133개 보안 통제항목의 정보보호관리체계((Information Security Management System) 인증을 획득하였고 이후 사후인증 심사를 받고 있다. 본 논문에서는 정보보호 국제 표준인증인 ISO 27001과 관련하여 NTIS의 정보보호관리체계에 대하여 국가R&D정보관리의 경영적 관점에서 실증적 현황 및 성과와 향후 개선 및 발전 방향에 대하여 검토한다. ISO 27001 도입 후 133개 통제항목 중에서 적용율이 증가하였고 중부적합/경부적합/개선권고 사항이 크게 감소하였으나 정보자산 및 개인정보 관리는 지속적인 관심과 개선이 필요함을 알 수 있었다.

Recently, labor unions' active participation in social issues is drawing people's attention as their concerns are expanding from the conventional wage raise and employment to others such as the environment and poverty eradication. This derives from the notion that a trade union with bargaining power is also an economic agent responsible and able to take a positive role in social issues. This paper explains through a micro economic analysis model that labor union movements can also contribute to social issues such as the global environment. Based on the international oligopoly trade theory, the study analyzes the principal-agent model whereby firms and labor unions pursue their strategic choices based on their interest and influence the implementation of regulatory policies on pollution emission. The analysis confirmed that labor unions' bargaining power and international cooperation are influential in alleviating global pollution emission and in improving social welfare. This conclusion could be presented as a basis for arguing for and requesting the participation and cooperation of labor unions to solve environmental problems discussed at WILL 2006.

The discovery of lunar ice in the lunar polar region has fueled international interest in in situ resource utilization (ISRU) and the construction of lunar habitats. Unlike Earth's atmosphere, the Moon presents unique challenges, including frequent meteoroid impacts, direct exposure to space radiation, and extreme temperature variations. To safeguard lunar habitats from these threats, the construction of a protective shield is essential. Lunar regolith, as a construction material, offers distinct advantages, reducing transportation costs and ensuring a sustainable supply of raw materials. Moreover, it streamlines manufacturing, integration schedules, and enables easy repairs and modifications without Earth resupply. Adjusting the shield's thickness within the habitat's structural limits remains feasible as lunar conditions evolve. Although extensive research on protective shields using lunar regolith has been conducted, unresolved conflicts persist regarding shield requirements. This study conducts a comprehensive analysis of the primary lunar threats and suggests a minimum shield thickness of 2 m using lunar regolith. Furthermore, it outlines the necessary technology for the rapid construction of such protective shields.

We are investigated about the state of the working circumstances and infection blocking facility within Metropolitan, Chungcheong and Gyeongsang regions in Korea. The result is as follows. The HAV vaccination rate is 35% and the HBV vaccination rate is 50% among the funeral directors. We expected that the infection risk of funeral directors was very high. Significantly, tuberculosis prevalence rate of funeral director was four times as high as the public. The wear rate of gown, mask, gloves showed relatively high than the others. The wear rate of individual protective equipments has decreased with work experience. The funeral directors have shown that there is difficult to get safe protection from infection. The personal hygiene of funeral directors and the infection blocking equipment should be strengthened institutionally. We are thought to recommend institutional support about infection management, individual protective equipment, vaccination of funeral director and guideline to avoid reversion to previous habitual behavior.

Present time, the mobile telecommunication companies of our country are still using independence wireless internet platform. So, this carry many difficulties to the phone company and content provider company. Because even they develop one product and they must make it prepare for some platform of every mobile telecommunication companies. And this make the development more longer and more expensive. For this reason, SKT, LG telecom and KTF develop the new wireless internet platform named WIPI with ETRI. and the working is still go on and go ahead with propulsion. And if it come to reality, the WIPI will attached from much of attack such as hacking or virus. But some data exchange between mobile phone is so important as to flow. Thus, in this paper, we are design and implementation the data encryption system working at the WIPI in order to protect the data, we want to protect.

We attempted to provide a way to improve job satisfaction by analyzing the relationship between the factors influencing job satisfaction directly or indirectly by the ecological system factors of long-term care worker who provide elderly care services at home benefit institutions. In this study, job satisfaction was confirmed to have a positive (+) correlation with all ecological factors except for social and cultural environmental factors by setting the causal relationship between the social and social characteristics of long-term care worker and job satisfaction as dependent variables. The factors with the highest correlation with job satisfaction were social support, followed by family support, job conditions, trust in welfare policies for the elderly, self-efficacy, and self-esteem. Therefore, it can be seen that nursing care workers who recognize positive support from the surrounding social network and family surrounding nursing care workers and positively recognize job conditions are generally positive.

This study was conducted to compare protected areas of South and North Korea based on international conservation criteria and recommend new fundamental directions for nature conservation policy. International conservation criteria used by this research were the 1994 IUCN protected area categories, composed of 6 management categories. Despite a variety of types and names of protected areas created by different domestic legislations, South Korea was revealed to have only two types of protected areas, Category IV and V, indicating the significant lack of ecological diversity and representativeness in its protected area system. Shockingly, there are no national parks meeting IUCN criteria in South Korea. On the other hand, North Korea has three IUCN Categories of II, III, IV and thus more balanced and ecologically representative protected area network than South Korea. Especially, North Korea maintains 9 national parks to be officially recognized by IUCN and UN. However, both South and North Korea should make sincere effort to have new and well-designed protected area system including all IUCN Categories I -Ⅵ and particularly a minimum area in the stricter protected area categories.
