Sprayed fire resistive materials are mainly used at steel structures to satisfy fireproof construction standard. However, the regulations on bond strength have been not considered with the exception of structures in the nuclear power plants, although it is an important factor showing material properties. Therefore, this paper suggested guidelines for bond strength of sprayed fire resistive materials used in the substation, by measuring bond strength according to aging of structures and impact loading considering environment of substations. It is judged that the bond strength suggested in this paper is the minimum value because it was measured from specimens widely used.

In order to manage forest recreation resources effectively, it is necessary to establish objective and quantifiable evaluative standards. They can be used to evaluate the present management conditions of recreation resources and to monitor the conditions continuously on the basis of the established evaluative standards. Normative approach is one of alternatives to help establish evaluative standards. Researchers and forest managers have been interested in the approach, and its usefulness in managing recreation resources has been emphasized. This paper evaluated the present conditions of the campgrounds on the basis of users' normative evaluative standards using the data collected by on-site survey at two campgrounds (Baemsagol Campground and Second Campground) in Chiri-Mountain National Park in 1.993. This paper established evaluative standards for eight impact indicators using normative approach, and it evaluated the present management conditions of the campgrounds on the basis of them. The present management conditions for noise time and littering behavior were worse than the evaluative standards at Baemsagol and Second Campground. Present conditions for inconsiderate behavior, number of tents, number of campers, and waiting time for using water supply were worse than the evaluative standards only at Baemsagol Campground. The present management conditions for distance between tents and waiting time for using restroom were better than the evaluative standards at both campgrounds. This study introduced how normative approach can be used to establish evaluative standards, and based on the study result, some management directions were suggested.

A dedicated short-range communications (DSRC) traffic information system is a detection system for a section of road using communication between roadside equipment and on-board High-Pass units to collect road traffic information and provide reliable traffic information to drivers. The Ministry of Land, Infrastructure, and Transport announced that a DSRC system must be supported to pass the performance evaluation of an intelligent transportation system (ITS), and the performance evaluation for DSRC systems installed in expressways and national highways is started. Currently, DSRC traffic information systems are only managed for maintenance and functional-monitoring purposes, which means that detailed criteria for the operation of a DSRC traffic information system, such as communication range, the direction of the antenna, and the power of the radio wave, etc., need to be established. In this paper, the criteria of the performance evaluation of a DSRC traffic information system are presented for different road types and road environments. The proposed performance evaluation criteria included the communication range and communication power of roadside equipment. In addition, installation criteria, such as the direction of the antenna, and the height and angle of the installed system, are presented for different road types and road environments. The criteria presented were evaluated for DSRC roadside equipment and documented to improve system maintenance and quality control of the communication system.

공동구는 도시생활을 영위하는 데 필요한 전기, 가스, 상 하수도, 전화, 통신 등의 공공시설물을 지하매설물 형태로 설치하여 시민들의 일상생활 및 사회 경제활동의 편의성을 제공하고 안전하고 안락한 도시환경을 유지시키며, 효율적인 도시운영이 가능케 하는 공공시설물이다. 그러나, 최근 들어 여의도 공동구 화재(2000년), 여수 공동구 침수(2003년), 구리시 전력구 화재(2006)등과 같이 공동구 및 전력구에서의 화재, 혹은 침수 등에 의해 재해가 발생하여 이로 인한 국가적 경제적, 사회적 손실이 늘어가고 있다. 하지만 국내에서는 공동구내 설비를 화재 및 재해로부터 보호하기 위한 법적 장치가 미비한 실정이며, 현재 운영되고 있는 공동구의 관리 또한 시설관리공단이나 위탁관리기관 등으로 분산되어 있어 일정한 시설물 설치기준이나 유지관리제도가 정립되지 못하여 효율적인 운영이 이루어지지 않다고 판단된다. 본 연구에서는 근래 국내에서 발생한 공동구 재해사례와 공동구 관련 법규를 검토 분석하였으며, 다양화되어 가는 공동구 수용시설 조건에 부합하고 체계적이고 효율적인 공동구의 시공을 위한 공동구 건설기준 제정방안을 도출하였다.

As the electronic medical records systems (EMRs) are introduced into the hospitals in Korea and the needs of chief stakehoders of medical records are changed, the environments related to creating and managing medical records has been changed dynamically. At this moment it might be meaningful to examine medical records based on records management principles rather than information management principles. The purpose of this paper is to apply the KS X ISO 1549 standards, which covers the principles of records management, to hospital medical records management and assess the current quality of medical records management, and define a few tasks of improvement for hospitals. To achieve this goal, this study has performed following activities: Firstly, principles that could be applied to medical records management were prepared for each record management steps described in the standards, such as capture, registration, classification, storage, access, trace and disposition, and 22 principles were selected from those 7 steps of the record management. Secondly, the Y hospital, which is affiliated with a medical school in Seoul, was chosen to evaluate the current situation regarding medical records management. The department head of the medical records management team in Y hospital was interviewed and the present status was evaluated according to each principle. Thirdly, tasks for improvement were suggested, in such stages as access, trace and disposition. With this study as a cornerstone, useful implications are expected to be gathered from future studies that apply standards for metadata of records, management systems for records, and record management systems to medical record management in hospitals.

The objective of this study is to improve the survey rate and reliability of survey control point marks, which serve as the foundation for location-based services. Within the scope of this research, we have inspected the current status and reporting systems for national control point marks, public control point marks, and cadastral control point marks, identifying various issues. To tackle these challenges, we have prepared proposals for new unit cost calculations for national control point mark inspections, enhancements to the inspection and reporting systems for survey control point marks, and preliminary reporting procedures for surveyors using these control point marks. Additionally, we have established a workflow to refine the process of survey control point mark inspections and have proposed an automated system for calculating the unit cost for unreported targets. The study anticipates that these changes will improve the efficiency of future survey control point mark inspection tasks.
