This study shows the result of the security assessment of the nationwide key energy facilities and suggests the ways of improving the security level. According to the study, most of the energy facilities are adequately equipped with physical security factors such as security personnel, security systems, fences, and guard posts, but lack of awareness is pervasive among those concerned, so the security operation is inefficient. In other words, inefficient deployment of security personnel, lack of the fundamental knowledge of the security systems, excessive dependence on surveillance cameras' functions such as Pan/Tilt/Zoom, misplaced cameras, low efficiency of monitoring, and irrelevant security plans. To solve these problems, above all, the authority concerned need to develop professional training programs to secure certified security mangers, and need to standardize security process to ensure consistency and to harness the standardization as a source of self assessment to improve security level.

The radiation has been utilized in a number of fields, even though the use of plenty cause a variety of side effects. This study was confirmed for radiation protective effects of aged garlic to contribute to the prevention of disasters that are radiation exposure. We studied the Complete Blood cell Count(CBC) and the small intestine after feeding aged garlic extract into Sprague Dawley Rat which irradiated X-ray beam 7 and 13 Gy. Garlic extract was administered to the results in the experimental group showed a notable difference in the CBC of platelets (p<0.05), red blood cells (p<0.05) and early damaged white blood cells (p<0.05). In addition, it was confirmed that experimental group's small intestine crypt is more survival than irradiation group significantly. And experimental group has small intestine villi length almost similar to the normal group. result of the aged garlic study will be able to be of great benefit for the radiation relevant emergency management.

방사성폐기물 관리는 이미 발생된 폐기물에 대하여 처리.처분하는 사후관리라 할 수 있으며 이에 앞서 폐기물의 발생량을 줄이는 방안 즉 사전관리에도 소홀히 해서는 안될 것이다. 사전관리는 방사능 관리구역내 불필요한 물품잔입금지, 소모성자재의 최대한 반복사용(방호복, 제염지등), 공기구동 미소모성자재는 방사능관리구역내 전용화, 제염방법의 개선, 반감기기 극히 짧은 핵종으로만 오염된 폐자재는 방사능이 충분히 감쇄할 때까지 관리구역내에서 보관후 비방사성폐기물로 처리, 폐기물중에서 비방사성폐기물을 분류하여 일반 폐기물 처리, 방사성물질 취급자의 교육등을 통해 방사성폐기물의 발생량을 억제할 수 있을 것이다. 세계 각국은 제각기 현실에 맞는 방사성 폐기물 처리기술을 도입 또는 개발하여 방사성 페기물 처리기술을 도입 또는 개발하여 방사성 폐기물의 양을 감용하거나 최종 폐기물에 대해서는 안전성을 향상시키고 있으며 또 처분은 각국의 지질이나 인문.사회적 환경을 고려하여 최적의 방안을 선택하여 최종처분하고 있다.

The research aimed to compare science curriculum between Korea and Israel and find out characteristics of science curriculum in Israel at middle school level. The middle school 'science' of the 7th revised national curriculum in Korea and middle school 'science and technology' in Israel were compared. Among characteristics of the Israel curriculum of 'science and technology,' distinct ones are as follows: First, 'science and technology' was most highly emphasized with the largest number of time allotment among all subjects at middle school level in Israel. Second, the contents of 'science and technology' were classified into seven areas of 'energy and interaction', 'materials', 'organism', 'earth and the universe', 'technological systems and products' . 'information and communication',and 'ecosystems' rather than four areas of energy, materials, life and earth in Korea. Third, 'organism' was allocated with the highest number of hours among seven areas. Fourth, objectives of each content of 'science and technology' were divided into three categories: scientific aspect, technological aspect, and social value and objectives of each category were related to one another. This characteristic seems to stress STS, multidisciplinary, and interdisciplinary approaches in 'science and technology' in Israel. Such characteristics of the 'science and technology' education in Israel are likely to make significant contributions to establish human resources of highly developing science and technology including IT, BT, NT, ST in the future society. Reflecting upon the characteristics of 'science and technology' education in Israel, Korea might seek for ways to improve its national power based on science and technology through strengthening science and emphasizing science and technology contents among school curriculum.

This survey was conducted between January 15, 2014 and February 25, 2014 to investigate the practice for infection prevention among dental hygienists. Data were obtained from 294 dental clinic worker who worked in dental hospital (clinics) of Gwangju and Chonnam. At the conclusion of this investigation, according to the conclusion of this investigation, the necessity of infection control education for dental hygienists and washing their gowns after caring infected patients affected the practice for infection prevention. They also well practiced the infection prevention working in dental hospital. To prevent infection in dental clinic, it is necessary to provide the continuing education programs for dental infection control to dental clinic worker.

Medical institutions wishing to install and operate diagnostic radiation generators must complete appointment training within one year of appointment based on the 「Medical Act」 and the 「Rules on Safety Management of Diagnostic Radiation Generator Devices」 which will come into effect on January 1, 2024. Additionally, You must receive supplementary education every three years from the date you received it. The strengthening of safety management for diagnostic radiation generators used in medical institutions means that although the radiation exposure that may occur when using diagnostic radiation generators is low, the risk of carcinogenesis may be higher than previously evaluated. In addition, safety management of diagnostic radiation generators can be said to be an essential requirement because it has been reported that the incidence of leukemia and other diseases is increasing in diagnostic radiation tests. However, the safety management training targets and programs for radiation exposure management operated by other organizations other than diagnostic radiation generators are significantly different. In addition, since the public institutions that are responsible for radiation safety management are divided, there is a risk of duplicative, excessive, and under-administrative application to medical institutions and educational institutions that install and operate diagnostic radiation generators. Therefore, we would like to determine their consistency by comparing domestic and foreign related cases and the provisions of the 「Medical Act」 and the 「Nuclear Safety Act」.

A Calculator-Based Laboratory (CBL) system was introduced to science teachers and their perceptions to its classroom application was assessed. A CBL survey instrument was responded by 54 middle and high school science teachers who undertook a three-hour workshop of science experiments with CBL system. There were significant differences in teachers perceptions to CBL system among gender, school level, school location, teacher's degree, and years of teaching in terms of learning CBL system, applicability of CBL system for science classrooms, and effects on science achievement. Male teachers showed significantly (p<.05) higher agreement to learning of CBL system and applicability for science classrooms than female teachers. Compared to middle school teachers, high school teachers showed significantly (p<.05) high interests in CBL applicability for science classrooms and perceptions that there will be an increase of science achievement. Teachers with 4-8 years of teaching experience also showed significantly (p<.05) higher interest toward learning CBL system and its applicability. It was concluded that science teachers perceived CBL system as a promising science teaching method in Korean middle and high schools. However, a science teacher inservice training program for CBL system should be developed in consideration of gender, school level, school location, and years of teaching.
