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.

Digital divide comes to appear as a new factor of causing social inequality with the entry of information society. Especially, the digital divide in student class makes a worry about education inequality as the education using ICT, e-learning, and u-learning are enlarged. So, the concern about the status of digital divide in school is increasing. In this study, we conducted a questionnaire survey of students and teachers in elementary and secondary schools located in Gyeongnam, and measured informatization level with the weighted average of three subindices : accessing index, capability index, and utilization index. According to the survey, the index on information processing capability showed the largest gap in both the student group and the teacher group. We also had the result of positive correlation between the capability index and the utilization index. These results show that the gap of information processing capability is an important factor for understanding the digital divide.

Our country's bidding system had made the lowest price successful bid system in foundation before introducing eligibility review system at July, 1995, and a averaged- price successful bid system or the restrictive-lowest price successful bid system had been enforced by repletion. However, they were introduced as dumping that do not reach in direct cost level of construction cost is generalized and worry about illegal construction practices rises by the lowest price successful bid system. According as they had not been promoted construction company's technical development effort or cost reduction effort, vicious circle that advocate competition principle again and recur as the lowest price successful bid system is repeated last 50 years. Therefore, I present improvement direction that can satisfy all Global Standard and real condition of our country through foreign countries example analysis to cope with the rapidly changing building circumstances socially and economically to correspond actively to the construction industry's reorganization to reconsider domestic construction engineering's competitive power.

Intolerance of Uncertainty is associated with numerous psychopathologies, including generalized anxiety disorders. However, several studies differ in the factor structures applicable for the Intolerance of Uncertainty Scale (IUS), and there exists a debate regarding the factorial and construct validity. Thus, in the current study, the IUS was newly translated to explore and verify the structures and factors relative to the cultural background of Korea. The study involved an exploratory factor analysis of randomly extracted data from 260 of 533 adults selected. Results determined that a prospective factor of 3 items and inhibitory factor of 5 items was appropriate. In addition, a confirmatory factor analysis and correlation analysis of the remaining 273 data revealed that a structural model comprising of the 8-items two factors model was well suited (x²=37.699, TLI=0.951, CFI=0.969, RMSEA=0.063, SRMR=0.039), and showed significant static correlation with worry, depression, and state-trait anxiety.

Recent years have seen an increased demand for calculators as a learning and teaching tool. It is asserted calculators should be utilized as an instructional tool before computers considering their lower price, connivence of easy, and variety of function. Towards this end, it is essential that we persuade teachers and parents who worry that the use of calculators would result in a decrease in students' ability to calculate. Specifically, effort should be made to point out the advantage that calculators have. First of all, calculators could lessen the mental and time pressure attendant upon paper-and-pencil calculation. It have also been reported that calculators are effective in teaching the concept unalgorithmal content, learning of principle, and problem-solving skills, In light of these advantages, this study investigates the kinds of practice items that can be included in the textbooks to help students develop computing skills using calculators.

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.
