Except the time when relics of a museum are exhibited or loaned to the public, they are stored in a storage. In addition, it is common view that collections are exhibited a few of total stored collections in a museum. Therefore, the environmental condition of a storage is an important factor. Hereby, the purpose of this study is to suggest the design guidelines of a storage for conservation of relics in a museum. The results from this study are as follows briefly. First, location of storages has to be located and centralized above ground against preservation environment and additional renovation. Second, for storage size, It is reasonable to secure long-term experimental data after planning about 20% of whole section in present domestic situation. Third, in order to prevent environmental deterioration due to short storage floor space, adequate storage height has to be secured against a mezzanine deck and spare storages need to be planned. Where a mezzanine deck is designed, detailed plans have to be supported for equal micro climate in a storage. Fourth, in respect of environmental control of storages, finish materials with adjustment ability on relative humidity have to be used after the system is installed jointly direct and indirect way by air chamber, considering domestic condition for management of intermittent ventilation.

The operation of a five day workweek seems to be increased continuously, Many city-workers will make good use of their spare time and search after a lot of devices that can seek for the maximum value of leisure utility. The demand of potential customers that want to enjoy weekend in farming villages is coming out greatly. That is, the condition of users that will travel the farming villages is getting better. But the actual states of farming villages are not ready in many parts yet. Therefore we must activate the tourist attraction in farming villages that can be satisfied the city-workers' expectation. And after making the sightseeing environment infrastructure, we must develop the programs intimate with environment, improve the sightseeing agricultural management and consolidate various systems as soon as possible. So in this study, after investigating the demand preference degree of city-workers, I tried to grope an activation plan with the base which will reach. Being more urgent what more, not the simple sightseeing agriculture that the farming experience was the focus of, but it is very important to develop the program of environment sightseeing agriculture. It will lay the stress on playing and education culture which city-workers can enjoy and experience. And with constructing the base facility like a city form, we must develop cheap and various goods and the execution of modernized weekend farms. For this, first the consciousness conversion against the customer management of farmers must precede and the change of government policy and the support polity is important. I hope that this study with the five-day workweek has the chance to contribute in the economic growth of farming villages and efficient use and management of the natural environment resources through the activation of sightseeing agriculture.

A group of studies revealed that family members of the seriously ill patient had some needs during the period of patient's hospitalization. Needs of the seriously-ill patient family could be classified into three aspect, i. e. needs on the prognosis of patient, needs on the well-being of family members themselves and needs on hospital environment. Several instrument were developed to measure the needs of the seriously ill patient, but their content tended to overemphasize the aspect of the prognosis of patient. The purpose of this study was to develop a new instrument to measure the needs in the aspect of the seriously ill patient's family themselves in details to increase the cummulative Percentage of the scale. Subjects were 134 family members of the seriously-ill patients, who were bung cared in ICU of seven university hospitals and data were collected from march 16, 1987 to April 11, 1987. The instrument used in this study was made by the author on the basis of results of literature review. Content valitity of the instrument was tested by a professor majoring in nursing and reliability by calculation of Cronbach's α with data of the respondents. Data was analyzed as follows, using SAS, computer system. Factor structures of the seriously ill patients' family needs were elicited by factor analysis. The programme was the Principal Component Factor Analysis Method of factoring employing Varimax Orthogonal Rotation. The influences of the demographic variables on the degree of the seriously-ill patients' family need were analyzed by t-test and P-test. Results were as follows. 1. Needs of the seriously-ill patients' family elicited and their cummulative percentage were: Needs to be supported emotionally, 29.2% Needs to be informed on facilities available, 9.6% Needs to be informed on the patient's prognosis, 7.7%. Needs to be supported spiritually, 5.1%. Needs to be informed on hospital environment, 4.2%. Needs to be helped to spare time, 3.9%. Needs to be informed on their role, 3.5%. Needs to be present near patient, 3.3%. 2. Educational background was found to influence on some factors. College-graduate group had higher Bevel of needs to be . informed on facilities available to be informed on the patient's prognosis, needs to be supported spiritually, needs to be helped to spare time, needs to be informed on their role than high school graduate group. 3. Among the parents, sons and daughters and the relative groups, the parents of the seriously ill patient had highest level of needs to be present near patient. Suggestions for further studies were as follows. 1. As the instruments used in the previous studies had high cummulative percentages in the aspect of the prognosis of patient and that in this study in the aspect of the prognosis of patient and that in this study in the aspect of the seriously ill patient's family themselves, development of a new instrument which combined the items of both of them is needed. 2. A study to clarify the influence of type and number of admission on need to be supported emotionally is needed.

최근 전력화되는 무기체계들은 최신 기술이 반영된 고가의 장비가 대다수이며, 운용유지비도 지속적으로 증대되고 있는 추세이다. 이러한 무기체계들을 효율적으로 운용, 유지하는 요소로서는 정비계획, 경제적 비용 및 수리부속 소요 등이 있으며 그 중 수명주기 동안 수리부속 소요를 사전에 예측하는 것이 운용유지비 효율성 증대와 운용가용도를 높이는 중요한 방식이라 할 수 있다. 수리부속 소요 분석의 시작으로는 무기체계 배치 시 동시에 보급되는 동시조달수리부속(CSP: Concurrent Spare Parts, 이하 CSP) 산정이라 할 수 있을 것이다. CSP는 무기체계가 초기 일정기간 동안 재보급 없이 주어진 운용임무를 성공적으로 수행하고자 하는데 목적이 있으므로 이 기간 동안에 운용가용도를 달성하는 필수요소이다. 현재 CSP 산정 방식은 품목의 고장율과 운용 시간 등의 반영하여 분석하고 있지만, 분석된 CSP는 기술적 고장을 대비하는 목적이며, 초도 운용환경에서 휴먼에러 등으로 인한 예기치 않은 고장 발생에 대처하는 부분에서는 제한적인 것이 현실이다. 해당 고장은 무상정비 범위에도 포함되지 않으며, 초도 운용기간 중 무기체계를 운용 불가 상태로 만드는 심각한 요소에 해당된다. 이러한 무기체계의 운용 불가 상태를 예방하기 위하여 초도 운용환경 중 휴먼에러를 고려한 CSP가 필요하며, 그에 대한 산정 방안과 기준을 제시한다.

본 논문에서는 우주 플라즈마 환경에서 정전기의 충전/방전 미카니즘 및 이에 대한 시스템 영향과 저궤도 위성 시스템의 설계규격에 대하여 고찰하였다. 우주의 플라즈마 환경에서 위성시스템에 대한 정전기 방전의 문제는 시스템 개발초기에 주의 깊게 다루어져야 한다. 일반적으로 정전기 방전과 관련한 시스템 설계는 전자파양립 성 규격에 나타나 있으며, 이들 규격에는 접지, 본딩, 차폐, 전도성 코팅, 전기적인 인터페이스 설계 등이 있다. 우주환경에서 충전은 위성체 표면위의 각각의 위치에 차등전위를 증가시키게 된다. 만약 이러한 충전이 스레쉬홀드까지 지속된다면, 경우에 따라서 위성 시스템에 심각한 영향을 줄 수 있다. 이러한 현상은 임무, 전기적/기계적 구성, 전원 및 궤도환경에 따라 결정된다. 그러므로 관련된 규격은 시스템 설계 및 운용환경에 맞게 테일로어링(tailoring) 되어야 하며, 시스템의 안전성을 위한 설계에 주의를 기울여야 한다.

In this study this author made research and analysis on physical status and characteristics of community parks in Ik-san provinces and also depending on its potential resources such parks were classified into constructed parks and unconstructed parks and status of use of such parks and level of satisfaction were studied. Through this paper this author strived to provide basic data required for forming green track of land for the parks. Required time for visiting community parks either constructed or unconstructed type was within 40 minutes or less. However constructed parks appeared to be more convenient for access in comparison with natural unconstructed parks. Mostly they were used by residents in neighboring community and also residents in the area around it were found as using it frequently. At the time of using community parks either constructed or unconstructed types means of access were mostly by walking or by riding bicycles. Thus considering large number of users of such parks are from neighboring community it appeared that parks with its simplicity and convenience in terms of distance and with rich nature were preferred by users rather than large scale parks at distance. In terms of time frame of use and motivation of visit constructed parks were used mainly for exercise and relaxation in the morning at parks and its facilities whereas un constructed parks were mostly used in the afternoon for for walking and chatting and rest under with time to spare at shadows of its trees. Time spent at parks were composed mostly of rest and walking more frequently than exercise and leisure activity thus it was different from motivation for visiting parks. As for evaluation of use of parks natural elements, unique environment, trees and lawns featured highly in unconstructed parks in comparison with constructed parks. Thus it seemed visitors are more conscious of forest and landscape in a form of unchanged nature. Thus for community parks first consideration should be heightening accessibility in view of primary concern for convenience by users rather than facilities or environmental conditions.
