The Yangdong traditional historic village is a representative village having symbolic historic values and unique combinations of natural, cultural, and social characteristics of a Korean historic settlement environment, which has been protected by Cultural Asset Protection Law since 1984. Now, in spite of its potential diverse powers, national strategies concerning Yangdong village do not have satisfactory direction and results. In consideration of this notion, this paper is designed to find and to understand the current state of Yangdong village. This paper aims to analyze The changes in Yangdong village between 1994 and 2002, and through these comparisons, to diagnose and predict future aspects of Yangdong village. Primary data was collected by questionnaire investigation between 1994 and 2002. The living conditions, production, and consciousness of residents of Yangdong village are utilized as standards of analysis. The final analysis results can be summarized as follows: because of the Cultural Asset Protection Law, noticeable changes have occurred in Yangdong village over the last 8 years. These change are different from the ones occurring in general farm villages. Also, most issues related to the changes are interpreted as occurring as a result of the top-down approach, which disregards the opinions and wishes of residents. For this, introduction of renovation concept that emphasizes modernization of life and production space is urgently required. To this end, it is necessary that concern for the traditional historic village should diversity and expand, and not concentrate solely on the cultural properties and architecture-oriented historic elements.

In this study, the properties of various material combinations were evaluated and an ideal material for fabricating protection pads for women's army combat uniforms was determined. Eight specimens were used for the evaluation: two types of materials, namely thermoplastic polyurethane for 3D printing, T and ethylene-vinyl acetate, E; two infill densities, namely 10%, 10 and 30%, 30; two types of pad designs, i.e., without holes, A and with holes, B; 2×2×2=8 and control E. The tensile strength, flexural strength, impact absorption, and weight of these specimens were evaluated. Results revealed that E was the most flexible material; however, its tensile strength and impact absorption were very low. Protection pads made from T (T-10A, T-10B, T-30A, and T-30B) had excellent tensile strength and impact absorption; however, they had low performance in ease of movement. Alternatively, protection pad with holes and an infill density of 30% produced using a combination of T and E had a high initial tensile modulus and exhibited excellent impact absorption. Moreover, it was flexible and light, which satisfies the standards and conditions required by protection pads. However, if T-E-10A and T-E-30B exhibited low impact absorption, as required, they can be regarded as appropriate materials for protection pads.

기존에 많이 사용된 반도체 검출기의 분해능은 통계학적 이론으로 그 분해능의 한계가 따른다. 이러한 이유로 최근에 반도체 검출기가 갖는 에너지 분해능의 한계를 뛰어넘는 저온 검출기를 이용하여 다양한 방사성 핵종 분석을 시도하고 있다. 본 논문에서는 $2{\times}2{\times}0.05mm^3$ 크기 금막 흡수체에 입사하는 에너지 때문에 흡수체의 온도가 상승하는 원리를 이용해 $^{241}Am$ 알파 선원의 에너지를 측정하였다. 흡수체의 온도 변화 측정에는 자기양자센서인 Au:Er를 이용하였으며 이는 순수한 Au에 핵스핀이 0 인 $^{168}Er$을 수백 ppm을 첨가하여 얻은 상자성 합금이다. 알파 입자 흡수에 의한 미세한 온도증가를 측정하기 위해서 희석식 냉동기보다 작동이 편리한 무냉매 자기냉동기를 이용해 mK 온도 영역의 저온환경을 구성하였다. $^{241}Am$ 선원 측정 결과 5.5 MeV에서 6.8 keV의 FWHM의 에너지 고 분해능을 얻었다.

Recently, the need for LBS (Location Based Services) is increasing with the rapid growth of the location measurement units, mobile devices, and communication technologies. Especially, wireless carriers are concentrating on LBS since it is regarded as so-called 'killer application' among wireless data services. Although LBS give us convenience and useful information, its use also raises privacy issues. There are quite possibilities that the people's locations are tracked by location measurement units while people do not recognize the existence of the units. To protect a person's location information, lawful and technical aspects should be considered. In this paper, we explain issues, regulations, standards, and platforms related to the protection of the location information. Finally, we suggest the architecture of a platform complying with the regulations and standards. It considers various issues not covered in other studies.

Asbestos is composed of long thin fibers approximately diameter $0.02\mu\textrm{m}$ and flexibility, strength, electrical, thermal conditions. The most common asbestos are : Chrysotile(white), Crocidolite(Blue), Amosite(Brown). Asbestos was first introduced in the Korea in 1960 and installation of these products continue through the late 1970's and even the early 1980's. Bu-pyung basement stores in Korea were surveyed from September 25 to October 26, 2001. The purpose of this research was to evaluate worker-exposure to asbestos, comparing to the standards and to research notice of inhabitants about asbestos. Fifteen personal samples and six areas were collected using Gillian Air Sampler. Result of this research were as follows. 1. The most of asbestos exposure concentrations keeps to the criterion(OSHA(Occupational Safety and Health Adminisoation), NIOSH) but forty three percent of the Six samples exceeded the EPA (Environmental protection Agency) of 0.01 fibers/cc. 2. All of places compliced to the standards but there is no "Safe level" of asbestos exposure to the people. Especially people who are expose more frequently over a long time are more at risk.

The concentration of radioactive elements was measured from the groundwater samples of Taejeon Area. U and Rn concentrations of very high level were detected from many places, especially around Yusung. These levels are much higher than the concentration standards for the drinking water proposed by the United States Environmental Protection Agency. However, in Korea, there are no standard levels for the radioactive elements in drinking water yet. We think that it is necessary to provide such standards as soon as possible, and that the determination of radioactive elements in groundwater should be included in the routine analysis items for the drinking water quality, because many people currently use such relatively high level radioactive groundwater as their drinking water, especially around Yusung area.
