본 연구의 목적은 여자 고등학생들의 운동행동변화단계 분포를 파악하고 운동행동 변화단계에 따른 신체활동량 및 운동제약요인과 운동자기효능감 및 회복탄력성을 비교·분석 하여 지속적으로 운동을 실천하고 이를 유지할 수 있는 체육교육 전략 및 방안에 필요한 기초자료를 제공하고자 하였다. 본 연구는 여자 고등학생 330명을 대상으로 설문조사를 통해 자료를 수집하였다. 그 결과 여자 고등학생 중 운동행동 단계가 유지단계인 경우는 8.4%에 불과하였으며 운동계획 전 단계가 24.0%나 되어 지속적 운동실천율이 매우 저조하였다. 운동행동단계에 따라 운동제약요인 및 운동자기효능감과 회복탄력성이 통계적으로 유의한 차이를 보였다. 이상의 결과를 통해 신체활동에 소극적인 여자 청소년들의 경우 운동행동단계별로 운동제약요인을 파악하고 이를 고려한 운동 프로그램 및 체육수업 등을 계획할 필요가 있으며 특히 운동제약요인을 스스로 효과적으로 관리하여 운동을 지속적으로 실천할 수 있도록 운동자기효능감과 회복탄력성을 높이도록 중재 방안을 모색해야할 것이다. The purpose of this study was to provide basic data on physical education strategies and methods for continuously practicing and maintaining exercise by analyzing the physical activity, constraint limitation, and efficiency of exercise. This study collected data from a survey of 330 female high school students. As a result, only 8.4 percent of female high school students were in the maintenance stage and 24.0 percent were in the pre-contemplation stage, resulting in a very low sustained exercise rate. Depending on the level of exercise behavior, there was a statistically significant difference in exercise constraint factors and self-efficacy. Female teenagers who are passive in physical activities through the above results need to identify exercise constraints and plan exercise programs and physical education classes considering them. In particular, they should seek arbitration to improve their self-efficacy.

Recently, plant design review by employing virtual plant is an important issue in the field of plant engineering. Especially, many researches for compactness and modularization were performed to reduce time, cost and space. So, the aim of this paper is development of design optimization techniques based on virtual plant for small-sized cryogenic plant such as ASU(Air Separation Unit). To do this, design optimized modules such as scale up/down, piping generation and navigator are developed by employing XVL(eXtensible Virtual world description Language). Finally, the availability of these modules is determined to apply the LNG(Liquefied Natural Gas) plant management system based on RAMS(Reliability, Availability, Maintainability and Safety) called as LPMS-RAMS. This result will be used to develop the web-based LPMS-RAMS.

Mucormycosis is an acute opportunistic infection caused by a saprophytic fungus found in soil, decaying fruits and vegetables. Numerous predisposing risk factors are associated with mucormycosis, although most cases have been reported in poorly controlled diabetics or in patients with hematologic malignant conditions. Throughout the history of mucormycosis, from the first case in humans reported in 1885 by Paltauf, through publication by Gregory et al of the first observation of rhino-orbital cerebral mucormycosis in 1943, to the report by Harris in 1955 of the first known survivor, little has changed in the diagnosis and outcome of this disease. Without treatment, the patient may die after an interval ranging from a few days to a few weeks. Regulation of diabetes mellitus and a decrease in the dose of immunosuppressive drugs facilitate the treatment of Mucormycosis. Extensive debridement of craniofacial lesions appears to be very important. intravenous amphotericin B is clearly of value. This is a case report of a patient with mucormycosis in maxilla. He was an uncontrolled DM patient, and for the treatment of intravenous amphotericin B and sequestrectomy were applied.

The aim of this paper is to develop the quantitative RBI program for LNG plant based on API RP(Recommended Practice) 581 code. To achieve this goal, API RP code is reviewed to make the algorithm and structure for RBI program. And the web-based quantitative RBI is developed as the interim result of LNG-RBI program. This result will be useful to develop another RBI program related to qualitative RBI and semi-quantitative RBI. Finally, these RBI programs will be combined as the LNG-RBI program.

Plants which are having conditions of high temperature and pressure always are exposed to danger. In order to prevent unexpected accidents, safety management that can effectively and appropriately examine facilities is required in plant operation. RBI(Risk-Based Inspection) technology in API 581 is one of standard management technique for evaluating risk on petroleum plants. There are qualitative and quantitative assessments in RBI methodology. Quantitative evaluation step is complex and required much information, so high-risk facilities in plant are selected firstly by qualitative method. Qualitative RBI is performed by choosing the answer in prepared questionnaire. However, it is difficult to believe thoroughly results from survey including ambiguous information. In this study, the procedure of qualitative RBI analysis with considering probability distribution concept were proposed by using Monte Carlo simulation method in order to increase reliability in spite of uncertain factors. In addition, qualitative risk of cooling system for LNG plant was evaluated using proposed procedure. Although 20 items of total 39 assessment items are applied to uncertain factors, risk section of high probability(89%) were verified. The detailed results were described in manuscript.
慶北地域 輸出實態와 合理化方案 : 大邱地域 輸出業體를 中心으로 Specializing in Daegu District
金周東 韓社大學 1981 대학논문집 Vol.11 No.-
Our export has grown remarkably since Korea undertook practical export beginning with 56.7 million dollars in 1962. The export of Taegu Diatrict, however, has shown decrease tendency relatively. This can be understood due to support of heavy and chemistry industry of government so far, but can be said owing to peculiar circumstances of Daegu District as follows. First, geographical condition is not good in executing bus-*iness. Now, commerce and Industry Authorities concerned are largely situated in Seoul. Therefore trade business has to be performed in Seoul in spite of burdening trading companies with lots of time and expenses loss. Second, export enterprises are too excessively composed of fibre industries. The exports of fibre goods indicate 82,3% among total exports of Taegu District in 1980, while they have been above 90% on an average in 1970. This proves that regional economy depends upon industrial fluctuation of fibre goods. Third, private companies are overwhelming in export enterprise shape and they are very small in scale. Taegu District has the most small or medium companies in our country. And so only 25% of all the export companies rely on direct export. Fourthly, the level of production technique is low. This problem is connected with most export products in our country, but especially in fibre goods, the main products of Taegu, the institutes for technology development and design fashion don't exist at all. Fifthly, production facilities have been old. About 20% of production facilities as of the end of 1979 are indicated to be old. Therefore international competition is becoming weaker than that of advananced countries in production cost and quality. Sixthly, Taegu doesn't have specialized trade organization to instruct the regional export companies and provide them with foreign market information. These six problems are indicated as main hindrance factors on export promotion of Taegu District. Therefore this writer believes that the expansion of the regional export should be made by settling the problems above mentioned one by one through positive cooperation between the regional Authority and business circles.
