Purpose: This research is to understand the effects of senior simulation on employees of elderly care facilities and utilize it in their job training. Methods: This research is a nonequivalence control group pre-to-post quasiexperiment research. 18 employees who have experienced senior simulation are set as test group and 18 other employees who have not experienced senior simulation are set as control group. Results: The hypothesis that 'the test group which has experienced senior simulation will show a positive change in their attitude on elderly care, compared to the control group' and 'the test group which has experienced senior simulation will show a positive change in understanding of elders, compared to the control group' was supported. The hypothesis that 'the test group which has experienced senior simulation will show a positive change in job satisfaction and performance of duties, compared to the control group' was dismissed. Conclusion: The senior simulation seems to contribute to elderly care facilities employees' change in their viewpoints of elders and broaden their understanding of them. The senior simulation was meaningful to provide basic help with implementing job training programs.

This study was conducted to examine the possibility of use as a structural material for ginseng cultivation facilities of recycled plastics. In order to determine the possibility that recycled plastic can replace timber used as a structural material for ginseng cultivation facilities, the specimens collected by elapsed time were compared with timber through bending tests. In addition, in order to analyze the effect of external environmental conditions on recycled plastic products, bending test was conducted with the specimens that had completed weathering test and accelerated heat aging test respectively. As a result, the bending strength of recycled plastic specimens with the elapsed time of 360 days was lower than that of timber. But bending strength of recycled plastic specimens exceeded the design allowable stress standard set by the Korea design standard (MOLIT, 2016). There was no degradation in quality of recycled plastic due to the external environment, and it was found that there would be no problem even if it was used as a structural material for ginseng cultivation facilities.

The salt contamination on the distribution facilities, such as suspension insulator, line post insulator, lightning arrester, COS, is one of the major coastal areas because more than 90% of salt contaminated failure occurs in distribution facilities. Did to stain distribution facilities artificially according to Equivalent Salt Deposit Density(ESDD) grade. The electrical test were performed on the non-polluted and polluted facilities(ESDD B, C, D grade).

Private electrical facilities are judged whether it is suitable for the insulation aging condition of their incoming underground cables using DC leakage current test method. In the case where the service point of utility is the secondary side of cut out switch installed in the electric pole, there is a problem that it is difficult to separate the lightning arresters(LA) because of their high position of the pole. Therefore, the field test voltage is applied at value lower than DC 30 kV, which are stated in the inspection guideline. However, this test could reduced the insulation performance of the LA by accelerating the electrical stress of the metal oxide varistor element in the pre-breakdown region. In this study, we analyzed the relationship between the DC test voltage and the leakage current using the non-destructive DC high voltage equipment with leakage current measurement function. The results show that the leakage current increases sharply above the specified test voltage. As a consequence, it could be contributed to improve insulation aging inspection method by selecting the possible test area on the VI characteristic curve of the pre-breakdown area of the LA.

항만 리모델링을 위한 콘크리트 시설물에 대한 평가가 필요하며, 특히 리모델링이 결정된 경우에는 소파 블럭이나 케이슨 블록 등에 대한 재활용 여부를 평가하여 재활용이 가능할 경우에는 유용하는 것이 경제적인 리모델링에 도움이 될 수 있다. 이 연구에서는 콘크리트 항만시설물에 대한 건전성 평가 및 재활용성 평가를 위하여 기존의 초음파 속도법을 비롯하여 슈미트 해머를 이용한 반발경도법, 충격반향법, 표면파 속도법 등의 비파괴시험을 실시하였다. 국내 5개 항만에 대하여 비파괴시험 및 시편을 채취하였으며, 채취한 시편에 대한 압축강도 시험을 수행하여 비파괴시험 결과와 비교하였다. 비파괴시험결과와 압축강도 시험을 통하여 콘크리트 재료의 탄성계수와 압축강도 등을 평가하였다.

In this paper, we consider various international and local standards and applied ontology concepts which are used in Semantic Web, to make more structured test methods/procedure. Based on the ontology concept, we classify test method as three categories (i.e., conformance test, interoperability test and performance test), and make test structures for each category. We believe that this research provides test methods which reflect various standards as well as the guidelines for users to construct RFID device software more structurally.

The purpose of this study was to investigate the characteristics of leisure facilities and to examine residents' needs for leisure facilities in apartment complex. The questionnaire survey and content analysis were used. The Data for content analysis were 476 site plans, and the subjects of questionnaire survey were 673 residents lilving in 35 apartment complex. Frequency, Percentage, and mean, ANOVA-A, x^{2}-test, and multiple regression were used for data analysis. The major results were as follows. 1) Facilities for children play, and senior, sports facilities, community center, green area, and resting place were included in leisure facilities in apartment complex. These facilities were different according to complex site and built-period. 2)The degree of satisfaction of leisure facilities was lower than neutral. The satisfaction of leisure facilities related with diversity of leisure facilities and program, and poor environment. 3) Subjects needed the facilities recommended in housing act including diverse leisure facilities such as sports center and resident's self government facilities. And they needed divers facilities for sports. 4) In terms of location, they needed leisure facilities which was closer to their house.

One of the most difficult and important problems associated with radiated electromagnetic emissions from digital devices are the determination of antenna factor and site acceptability of an open area test site. This paper presents the problems of the open area test site and EMC antennas far measuring electromagnetic interferences radiated from the equipements. It seems desirable that the antenna factor of EMC antennas be revised to the antenna factor with zero reflection presented in this paper for accurate measurements.

생활폐기물 처리용량이 일일 50톤 이상인 소각시설에 대한 배출가스중의 다이옥신 농도는 신규시설인 경우 $0.1ng-TEQ/Nm^3$, 기존시설인 경우 $0.5ng-TEQ/Nm^3$로 규제하고 있으며, 기존시설인 경우에도 2003년에는 $0.1ng-TEQ/Nm^3$로 강화할 예정이다. 이들 소각시설은 다이옥신 측정분석기관으로부터 년 2회 이상 배출가스중의 다이옥신 농도를 측정하여야 한다. 현재까지 7개 기관이 다이옥신 측정분석기관으로 지정을 받았으며, 이들 기관은 매년 국립환경연구원이 제공하는 정도관리 프로그램에 따라 평가를 받아야 한다. 1999년에는 1998년에 지정받은 4개 기관에 대하여 M 소각시설에서 대기오염공정시험방법에 따라 다이옥신 시료채취 및 분석을 하여 정도관리를 실시하였다. 정도관리 실시결과 등속흡인계수는 각각 100.9%, 102.4%, 102.1%, 99.2%로 4기관 모두 양호하였으며, 분해능 (10,000 이상), 질량검정 결과(${\pm}5ppm$ 이내), 동위원소 존재비 (15% 이내) 및 회수율(50-120%) 모두 대기오염공정시험방법 기준을 만족하였다.
