In recent years, the construction of high-rise buildings are promoted. According to these, there are many needs about new technologies to strengthen the building performance and high-strength steel is regarded as one of these for promoting building performance. In Korea, high-strength steels which stress are over 600MPa are on market and in aborad, super high-strength steels over 1000MPa are developing and they expected to promote the building performance. But there are still doubts about applying high-strength steel members because of size effect and worry of brittle fracture. In this reports, we propose results of performance and analysis tests for use with general steel. We propose the characteristic of high-strength steels first and next the results of performance test to show they satisfy the performance that designers expect. And last, we compare the results of test and analysis for acquire the alanysis reliability in non-linear analysis with high-strength steels.

A study .to identify an occupational hazards for hospital working health care providers from needle stick injury as an occupational hazards of health care providers in hospital and prevention A survey of 2430 health professionals (2184 nurses, 182 doctors, and 64 Lab technicians) was conducted to describe and provide information about 1) the experience of needle stick. 2) the number of needle stick, 3) the treatment after needle stick. 3) the situation of needle stick, 4) the report of needle stick, 5) the cause of needle stick, 6) the discard method of used needles, and 7) how to worry about getting infection disease after needle stick. Data were collected using questionnarires constructed by the authors and tested by a pilot study. Results of the study showed that 96.7% of the sample had an experience of needle stick (96.8% of the nurses, 96.7% of the doctors, and 92.2% of Lab technicians). Seventy seven percent of the sample experienced less than 10 needle sticks, 19% of the sample experienced 11 to 20 needle sticks, and the rest of the sample experienced more than 20 needle sticks. The situations where needle sticks occurred include intrvenous injection (36.5%), intramuscular injection (21.6%), blood withdraw (17.8%), and preparation(11.8%). The study showed that needle sticks (67.5%) usually occurred after client treatment. Health professionals used recapping method (55%) after they used needles. Needle sticks were predominantly caused by the carelessness of health professionals (61%), After needle sticks, 88.2% of the sample subjects treated needle sticks using disinfection technique by themselves. Most of health professionals (92.6%) did not report the accident. and 95.6% of them did not receive any test or further treatment. After needle sticks, 87.8% of nurses, 83.6% of doctors, and 96.6% of lab technicians worried about hepatitis infection. 'Health professionals also worried about AIDS infection, tetanus, venereal infection, and skin injury. These findings suggest that health professionals are at high-risk of needle stick and fail to report needle stick accidents. They should pay more attention to needle stick in order to avoid unwanted infection.

우리나라의 입${\cdot}$낙찰제도는 1995년 7월에 적격심사제도를 도입하기 전까지 최저가 낙찰제를 근간으로 삼아왔으며, 평균가 낙찰제나 제한적 최저가낙찰제가 보완적으로 시행되어 왔다. 하지만 최저가 낙찰제도에 의해 공사비의 직접비 수준에도 미치지 못하는 저가투찰(덤핑)이 일반화되고 부실공사에 대한 우려가 높아지면서 평균가 낙찰제나 제한적 최저가 방식이 도입되었다. 그러나 평균가낙찰제나 제한적 최저가낙찰제가 건설업체의 기술개발 노력이나 원가절감 노력을 촉진시키지 못하는 문제점이 부각됨에 따라 또다시 경쟁원리를 내세워 최저가 낙찰제로 회귀하는 악순환이 지난 50년간 반복되고 있다. 따라서 사회 ${\cdot}$ 경제적으로 급변하는 건설 환경에 대처하고 건설 산업의 구조개편에 적극 대응하여 국내 건설엔지니어링의 경쟁력을 재고하고, Global Standard와 우리나라의 실정을 모두 충족시킬 수 있는 개선방향을 해외 사례 분석을 통해 제시하고자 한다.

지금 까지 여러 세기 동안 초등학교에서의 수학은 기초적인 연산과 같은 지식의 향상에 중점을 둔 교육이었다. 이제는 정보화 시대에 알맞게 계산은 빠르고 정확하게 수행할 수 있는 도구를 사용하고 논리적 사고력과 창의력을 기를 수 있는 시간으로 변화해야 할 시대가 되었다. 교육 현장에 최초로 계산기와 컴퓨터가 수학 학습의 보조 도구로 등장하였을 때, 많은 사람들은 이들의 사용이 학생들의 계산 능력의 저하와 두뇌 발달 등에 부정적인 영향을 가져올 것이라는 우려를 하였다. 그러나 최근 초ㆍ중등학교에서 계산기를 사용하여 나타난 연구결과에 따르면 예상보다는 바람직한 교육의 성과를 얻고 있다는 연구 결과가 계속 발표되고 있다. 이제 논의 초점은 계산기를 어떻게 활용하는 것이 보다 적극적이고 효과적인가에 대한 방향으로 변화가 있어야 한다. 그러한 변화를 유도하기 위해서 본 연구에서는 가장 강력한 교수ㆍ학습매체인 교과서에서 계산기를 활용할 수 있는 문제의 유형을 제시하고 이를 활용할 수 있도록 하였다. 상당수의 학생들이 펜티엄급 컴퓨터를 사용하고 있는 현실에서 전통적인 학습만을 고집한다는 것은 이제는 바꿔져야 할 때가 되었다.

The purpose of this study was to find out the various opinions of Oriental Medical Doctors to give the recommendations for making the proper policy of the supply and demand of Oriental Medical specialist. This study was desinged of 480 doctors who answered about questions that is composed of 105 Oriental medical specialist, 227 Apprentice doctor and 148 Oriental Medical doctors. On the assumption that there are many different situations and visions about the Oriental medical specialty system, we wanted to know about the each situations and visions about oriental specialty system. Generally, as one grows older, they adapted high proportion about the propriate number of specialist. About this difference from each generations, we can explain that young doctors more worry about the supply of specialist. As well each achievement, the more higher achievement, the more higher proportions of specialist is adapted. Answers about the number of present specialist, the more aging the more negative response about the number of present, number of specialist, this is because of the proprotions who wanted to be a specialist in open doctors. About the property of the number of specialist, there are many different views in each other groups. Anyway it is important that hearing the opinion of each Oriental Medical Doctors for the better Oriental Medical System.

The districts of underground geologic structure in Jeju island where underground air is distributed are lava cave, pyroclastic, open joint, and crushing zone. Such districts are identified to secure an enough airflow when air ventilation layer is to secure 25-35m in depth. In Jeju, Ground air is used for heating greenhouse and fertilizing natural $CO_2$ gas by suppling directly into greenhouse. But the heating method by suppling ground air into greenhouse directly bring about several problem. The occurrence of disease of the crops by high humidity is worried because the underground air which becomes discharge from underground air layer has over 90% relative humidity. The underground air is inadequate in heating for crops which need high temperature heating such as mangos, Hallbong and mandarin orange because the temperature of it is $15{\sim}18^{\circ}C$. Also There is worry where the ventilation loss becomes larger because the air pressure inside greenhouse is high by supplying underground air directly. In this study the heat pump system using underground air as heat source was developed and heating performance of the system was analysed. Heating COP of the system was 2.5~5.0 and rejecting heat into greenhouse and extracting heat from underground air were 40,000~27,000 kcal/h, 30,000~18,000 kcal/h respectively.

Objectives : The purpose of this study to provide preliminary data to effective halitosis control. Methods : A survey was carried out the self-perception of causative factors of halitosis in 98 female college students in Chungnam province. In addition, the levels of oral gas and breath gas were measured by use of the B&B checker, and an analysis was made of the correlation between halitosis and obsessive-compulsive disorder (OCD). Results : 1. Subjective halitosis awareness degree different degree of dryness, 'None', 'some', 'little' people who feel as the 'little fly' (68%), 78.3%, 70% was higher (p<0.05), halitosis interest 'very worried', 'worry', 'normal' person with a' not at all 'to 58.3% higher (p<0.01). 2. In regard to OCD severity, 49.0%, 34.7% and 16.3% were found to be mild, moderate and severe respectively. Halitosis tended to be severe in proportion to OCD severity, which was statistically significant (p<0.05). 3. Oral gas had a positively correlation with breath gas (r=0.329, p<0.01), but had a negative one with OCD severity (r=0.204, p<0.05). Conclusions : Symptoms of oral dryness and halitosis interest were associated with self-perception of halitosis. The levels of oral gas and breath gas were in inverse proportion to OCD severity. Hereat, it needs to analyze psychogenic factors properly as regards the diagnosis or treatment of halitosis.
