The purpose of this paper is to gather information and opinions to better guide the direction for implementing improvements of the senior centers' indoor environments located in Jeonju residential areas, by surveying the users about the level of satisfaction and analyzing the result in relation to the current situation. Senior centers located in Jeonju residential areas were operating the facilities with low financial support from the local autonomous entity. According to the results of the survey, most of the users tend to use the facilities between 12p.m. to 6p.m., and the majority have lunch at the senior centers. Most of the senior centers already have cooking facilities, without a dining room, except one place, and even the facilities they have are very poor. In a thermal environment area, the temperature is mostly above in summer or below in winter the appropriate temperature, especially the temperature of the restroom of all senior centers are below $20^{\circ}C$ in winter. The density of carbon dioxide is above average in most indoor areas. However, the users' level of facilities' satisfaction was positive. To improve the seniors' quality of life, the local autonomous entity has to start regular check-ups and repair of the poor indoor environment and facilities, with more financial support and active supervision by senior center the management.

In order to advance into the MRO industry, the Aviation maintenance organization with suitable for the standards for personnel, facilities and operations should be first approved by FAA and EASA. The purpose of study is designed to arrange the standards required for personnel, facility, operation rule for approval of Repair Station maintenance organizations certified by FAA PART 145 of the US Federal Aviation Regulation. Also to consider the following differences through the comparative analysis with domestic AMO certification of the information in the Management, Maintenance Process, and Quality System for approval of maintenance organization authorized, the additional EASA PART 145. As a comparative analysis on maintenance organization certification in the country between FAA and EASA, this study could show us that domestic maintenance organization, certified manual contents are used by applying just many of the FAA system. And we could know that as part of the EASA maintenance organization certification process, airmen personnel were relatively systematically segmented and controlled. For domestic maintenance organization certification, operational as policy implications we would like to present policy implications such as the implication of rating system of Aviation Mechanic License like EASA, the financial support of the training center to resolve the shortage of the FAA or EASA license holders, operational organization as "CAMO" for systematic aviation mechanic certified system should be required, continued construction of hangar or MRO for airworthiness repair under Governmental support, and varied application of DER system from FAA accordingly.

Background : A 35-year-old woman was admitted to the emergency room with sudden dyspnea that developed one day prior. The initial Chest X-ray showed multiple bullous changes at the right middle and lower lung field and long standing fibrotic tuberculous changes at the right upper lung field. The left lung field was totally collapsed by an fibrotic old tuberculous lesion. In spite of supportive medical care with oxygen therapy after admission, the radiographic lesions were no significant change but the respiratory distress had worsened. The patient suffered respiratory failure and received mechanical ventilatory support. The HRCT showed a localized tension pneumothorax mimicking multiple giant bullae at the right lower lung field. Immediately after a closed thoracostomy with a 32 French chest tube and air drainage, her vital signs and dyspnea were gradually improved. The patient was successfully weaned from mechanical ventilation after 5 days of mechanical ventilatory support. The patient had received talc pleurodesis through a chest tube to prevent the recurrence of the life-threatening localized pneumothorax. The patient was discharged without recurrence of the pneumothorax.

The purpose of this study was to identify the needs which were perceived by patients who were received spinal anesthesia for surgery. The subjects consisted of 50 adult patients who were admitted to 2 university hospitals and 2 general hospitals in Pusan city and 1 general hospital in Koje City for surgery under spinal anesthesia. Thirty eight percent of subjects received information about anesthesia before the operation. The instrument for this study was developed by the researcher based on literature and a pretest. Data were collected from December 10, 1999 to February 10, 2000 and were analyzed by content analysis. The results were that there were 533 meaningful statements in the needs of spinal anesthesia patients. The needs of spinal anesthesia patients had 51 items (preoperation (6), induction of anesthesia(5), intraoperation (27), postoperation(13)) and 6 categories (information, emotional welfare, physical welfare, post anesthetic management, control of physical environment, humane treatment). From the results, it can be concluded that: 1. In the pre-operation period, we have to explain anesthesia procedures, adequate position of anesthesia, duration before anesthesia wears off and sensation of paralysis. We have to supply emotional support to relieve anxiety because of anesthesia. 2. In induction of anesthesia, we have to support patient's position for anesthesia, and relieve anxiety so that patients participate in induction of anesthesia well. 3. In intra-operative period, we have to check the level of anesthesia, and keep up a comfortable position for operation and care for physical discomfort such as thirst, nausea, vomiting, dyspnea and to maintain body temperature of the patient. Since the patient is conscious, we have to communicate with the patient to relieve anxiety, maintain privacy, inform the patient of the process of the operation and encourage the surgeon to explain the outcome of the operation. The operating team needs the careful about what they say and to place the instrument well. We have to ventilate the room air and reduce noise. 4. In the post-operative period, we have to explain the purpose and duration of bed rest, complications of anesthesia and care for physical discomfort such as pain, dysuria, headache, backache. Also we have to maintain body temperature of the patient and maintain privacy.

무인기의 INS/GPS/기압고도계 결합항법 시스템에서 비행체 자체 항법 정보만을 이용하여 QNH 혹은 QFE 방식의 기압 고도계를 설정하는 방법을 제안한다. 본 설정 방법은 비행체 외부로부터 주어지는 대기나 고도 정보에 의존하지 않고 자체 항법 시스템의 정보만을 사용하며 설정 방법에 따라 요구되는 일정 형태의 비행을 통해 얻어진 정보를 수학적으로 처리하여 기준값을 산출한다. 비행체 자체 정보만을 사용함으로써 지상 지원 장비에서 대기 정보 측정 시스템을 제외하는 등 간소화나 지원 시설의 요구 조건이 완화될 수 있고 지상 지원이 가용하지 않는 영역에서의 비행도 가능하다. 특히 회귀 분석 기법을 이용한 방법은 고도와 기압, 온도의 세 가지 기준값을 설정함에 있어 고도와 기압, 두 가지 정보만을 요구하며 온도 자료가 필요하지 않다. 그러므로 기압 고도 산출에 온도 정보가 전혀 필요하지 않아 비행체의 대기 정보 측정 시스템도 간소화될 수 있다.

The emergency response modeling system CARIS has been developed at CCSM (Center for Chemical Safety Management), NIER (National Institute of Environmental Research) to track and predict dispersion of hazardous chemicals for the environmental decision support in case of accidents at chemical or petroleum companies in Korea. The main objective of CARIS is to support making decision by rapidly providing the key information on the efficient emergency response of hazardous chemical accidents for effective approaches to risk management. In particular, the integrated modeling system in CARIS consisting of a real-time numerical weather forecasting model and air pollution dispersion model is supplemented for the diffusion forecasts of hazardous chemicals, covering a wide range of scales and applications for atmospheric information. In this paper, we introduced the overview of components of CARIS and described the operational modeling system and its configurations of coupling/integration in CARIS. Some examples of the operational modeling system is presented and discussed for the real-time risk assessments of hazardous chemicals.
