Citizen perception is increasingly emphasized as one of the critical factors in establishing public policies including river management. Our results show that citizens expect integrated river management by specialized river management organization. We found that the river condition was perceived more negatively than the actual status of water quality and river ecosystem by citizens. The gap in perception implies that it is important to restore the reliability of river management. Therefore, it is necessary to encourage organizations with public trust to participate in river management. and credible river management policies should be established and implemented.

유비쿼터스 컴퓨팅의 핵심 구성요소인 웨어러블 컴퓨터는 배터리를 기반으로 운영되므로 웨어러블 컴퓨터의 사용 시간을 늘리려면 효과적인 전력관리가 필요하다. 본 논문에서는 웨어러블 컴퓨터의 전력관리를 위한 컴포넌트 형태 미들웨어에 대한 구현 상황과 그 성능에 대해 기술한다. 구현된 전력관리 미들웨어는 전력인지 인터페이스, 전력관리 모듈과 전력관리 미들웨어 인터페이스로 구성된다. 구현된 전력인지 인터페이스로 전력관리 미들웨어 인터페이스는 다른 미들웨어 컴포넌트 개발자나 응용프로그램 개발자에게 시스템에 투명한 전력관리 기법을 제공할 수 있다. 성능 측정 결과, 구현된 전력관리 미들웨어를 이용하여 LCD 화면 밝기와 블루투스 장치 검색 메시지 주기를 조절할 경우, 웨어러블 컴퓨터의 이용시간이 약 2배 이상 증가하였다.

In this study, international standards in disaster management and the management of the relevant International Standards Organizations(ISO), in particular ISO / TC 292 (Security- Safety) research subcommittee to look at international standards of relevant international standards for disaster management trends, each international domestic law related to the standard were researched. National Disaster Management Authority as a Ministry of Public Safety and Security (formerly the National Emergency Management Agency) has continued to prepare a plan for applying national disaster management relevant to the international standards. As the disaster management international standard continues to be established, disaster management agencies need to continue to keep pace with the international community to find ways to introduce international standards.

As the performance of the next-generation broadband wireless networks is dramatically enhanced, various services (i.e., education, video conferencing, online games, etc.) have been provided to users through a smart mobile platform. Since those services are usually provided by using the centralized architecture, it is difficult for a lot of users to provide the scalable communication service with regard to traffic management. To solve these problems, we have proposed an architecture of P2P-based group communication management scheme using smart mobile device. More specifically, we design the group management protocol and algorithm for the group member management and the traffic management. By using these methods, the mobile multimedia streaming service can be provided with scalability. In order to verify the performance of the proposed scheme, we have mathematically analyzed the performance in terms of the average transmission delay and bandwidth utilization.

The purposes of this study are to define the scope of occupational health management and to classify occupational management by review of related journals from 1945 to 1994 in Korea. The steps of this study were as follows: (1) Search of secondary reference; (2) Collection and review of primary reference; (3) Survey; and (4) Analysis and discussion. The results were as follows ; 1. Most of the respondents majored in occupational health(71.6%), and were working in university (68.3%), males and over the age 40. Seventy percent of the respondents agreed with the idea that classification of occupational health management is necessary, and 10% disagreed. 2. After integration of the idea of respondents, we reclassified the scope of occupational health management. It was defined 3 parts, that is , occupational health system, occupational health service and others (such as assessment, epidemiology, cost-effectiveness analysis and so on). 3. The number of journals on occupational health management was 510. It was sightly increased from 1986 and abruptly increased after 1991. The kinds of journals related to occupational health management were The Korean Journal of Occupational Medicine(18.2%), Several Kinds of Medical Colloge Journal(17.0%), The Korean Journal Occupational Health(15.1%), The Korean Journal of Preventive Medicine(15.1%) and others(34.6%). As for the contents, the number of journals on occupational health management systems was 33(6.5%) and occupational health services 477(93.5%). Of the journals on occupational health management systems, the number of journals on the occupational health resource system was 15(45.5%), occupational finance system 8(24.2%), occupational health management system 6(18.2%), occupational organization 3(9.1%) and occupational health delivery system 1 (3.0%). Of the journals on occupational health services, the number of journals on disease management was 269(57.2%), health management 116(24.7%), working environmental management 85(18.1%). As for the subjects, the number of journals on general workers was 185(71.1%), followed by women worker, white coiler workers and so on. 4. Respondents made occupational health service(such as health management, working environmental management and health education) the first priority of occupational health management. Tied for the second are quality analysis(such as education, training and job contents of occupational health manager) and occupational health systems(such as the recommendation of systems of occupational and general disease and occupational health organization). 5. Thirty seven respondents suggested 48 ideas about the future research of occupational health management. The results were as follows: (1) Study of occupational health service 40.5%; (2) Study of organization system 27.1%; (3) Study of occupational health system (e.g. information network) 8.3%; (4) Study of working condition 6.2%; and (5) Study of occupational health service analysis 4.2%.

The problems of environmental pollutions and resources depletion have been growing issues in global construction recently. Efforts to reduce $CO_2$ emission have been also made in all sectors of construction industry these days. As one of the biggest industries that consume a huge amount of resources and generate complex construction wastes, the construction industry has significant impacts on environment issues. However, systematic approach to manage wastes has been rarely made, and most construction wastes from construction sites are being land-filled or incinerated. In this study, a system is proposed to predict the amount of wastes in visual formats, and to control the process of wastes management. The system's main functions include : (1) to estimate the amount of wastes to be generated in project schedule, (2) to categorize the types of wastes, (3) to determine the timing of taking out wastes from sites, and (4) to share information regarding wastes for recycling. A huge amount of wastes are generated in construction process, but most of the wastes have been discharged in forms of mixed wastes, which make them hardly reused. The system not only provide information on wastes to be generated, but also prevent mixing various wastes by classifying them by types and schedules. This features of the system, along with functions to share wastes information with other agencies outside the site, are expected to enhance the level of wastes recycling to a great extent. By saving construction materials through wastes recycling, the system also contributes in reducing $CO_2$ emission.
