The Korea Electric Power Research Institute (KEPRI) has developed performance demonstration programs for non-destructive testing personnel who analyze ECT(eddy current testing) data for steam generator tubing since 2001 The purpose of these performance demonstration programs is to ensure a uniform knowledge and skill level of data analysts and contribute to safe operation of nuclear power plants. Many changes have occurred in non-destructive testing of steam generator tubing such as inspection scope, plugging criteria and qualification requirements. According to the Notice 2004-13 revised by the Ministry of Science and Technology (MOST), the analyst for steam generator tubing shall be qualified as the qualified data analyst (QDA), and the site specific performance demonstration (SSPD) program shall be implemented. KEPRI developed these performance demonstration programs and they are being successfully implemented. The analyst's performance is expected to be improved by the implementation of these programs.

본 논문에서는 국내 원자력발전소 초음파검사자 기량검증시험 결과를 검토하였다. 원자력발전소 안전관련 설비에 대한 초음파검사 기량검증 요건은 ASME B&PV Code Section XI 1989 겨울 부록에서 최초로 언급되었다. 한국수력원자력(주)은 ASME Code Section XI, Appendix VIII의 요건 적용을 위해 국내 원자력발전소에 적합한 한국형 초음파검사 기량검증(KPD) 시스템을 개발, 규제기관의 승인을 받아 2004년 7월부터 운영하고 있다. 본 논문에서는 2004년부터 2013년까지 수행한 초음파검사자 기량검증시험 결과의 검토 내용으로 초음파검사 결함 검출 향상 및 기량훈련시스템 연구 개발에 도움을 줄 것으로 기대한다.

This study describes thermal performance of heating and cooling demonstration system using ETSC(Evacuated tubular solar collector) installed at Seo-gu art center of Kwangju. For demonstration study, a reading room with about $350m^2$ was heated and cooled using that system. The demonstration system was consisted of ETSCs, storage tank, hot water supply tank, subsidiary boiler, and subsidiary tank. From January to March in 2006, demonstration test were performed with 4 control mode to find the optimum control condition for solar thermal system. After experiments and analysis, this study found that solar thermal system of control mode IV was corresponded to 78% for the hot water supply and 49% for space heating.

This study describes thermal performance of heating and cooling demonstration system using ETSC(Evacuated tubular solar collector) installed at Seo-gu art center of Kwangju. For demonstration study, a reading room with about $331m^2$ was heated and cooled using that system. The demonstration system was consisted of ETSCs, storage tank, hot water supply tank, subsidiary boiler, and subsidiary tank. From January to March in 2006, demonstration test were performed with 4 control mode to find the optimum control condition for solar thermal system.

과거 집시법이 예정하지 못했던 우발적 시위, 긴급집회, 해상시위, 자동차전용도로상의 시위 등 시간적, 장소적 특성을 지니는 새로운 유형의 집회시위가 사회적으로 문제되고 있다. 특히 이 중에서 해상시위에 대하여 집시법을 적용할 수 있는지, 있다면 어떠한 논리를 전개해야 한지 내지 적용할 수 없다면 어떠한 법을 적용해야 한지가 공법영역에서 문제되고 있다. 그 동안 학설은 소극적, 적극적 입장으로 대립하여 왔지만, 해상시위는 장소적 자가결정권에 입각한 헌법상 집회시위자유권의 하나로 보장되어야 한다, 이에 따라 집시법상 집회시위개념은 헌법에 합치되는 방향으로 해석되어야 하므로 해상시위와 같은 집시법상 비전형적 집회에 집시법을 유추적용 한다든지 아니면 경찰관직무집행법과 감은 일반경찰법을 적용하여야 한다간 견해간 설득력이 없다. 그리고 현대적 시위상황에 비추어 해상시위도 소수자보호를 위한 민주주의적 기능을 보유한다는 것을 그려할 때 집시법을 직접 적용하여 규율함이 정당하다.

Unidimensional construct of conspicuous consumption which focuses on the ostentation of the economic assets are limited in describing today's consumers. We propose that both ostentation of social status and demonstration of uniqueness through overt consumption should be considered in the realm of conspicuous consumption. This research aims to examine the two dimensions of conspicuous consumption tendencies and their impact on new product adoption intention, which is mediated through the perceived value of the new products. This research empirically validates the theoretical conjecture by conducting an online survey (N=272). Our empirical findings reveal that ostentation of social status influences new product adoption intention both directly and indirectly through perceived social value, while demonstration of uniqueness improves new product adoption intention only indirectly through perceived utilitarian and hedonic value. This research identifies the ostentation of social status and demonstration of uniqueness as two dimensions of conspicuous consumption and refines scales to measure them. In addition, this research identifies conspicuous consumption as a driver of new product adoption intention and recognizes the mediating role of perceived value.

Deep geological disposal using a multibarrier system is a promising solution for treating high-level radioactive (HLRW) waste. The HLRW canister represents the first barrier for the migration of radionuclides into the biosphere, therefore, the corrosion behavior of canister materials is of significance. In this study, the electrochemical behaviors of SS316L, Ti-Gr.2, Alloy 22, and Cu in naturally aerated KAERI underground research tunnel (KURT) groundwater solutions were examined. The corrosion potential, current, and impedance spectra of the test materials were recorded using electrochemical methods. According to polarization and impedance measurements, Cu exhibits relatively higher corrosion rates and a lower corrosion resistance ability than those exhibited by the other materials in the given groundwater condition. In the anodic dissolution tests, SS316L exposed to the groundwater solution exhibited the most uniform corrosion, as indicated by its surface roughness. This phenomenon could be attributed to the extremely low concentration of chloride ions in KURT groundwater.

Purpose: The purpose of the study was to compare community residents' perceptions, participation, satisfaction, and behavioral changes between a health promotion demonstration health center and general health center. Method: The design of the study was ex-post facto that compared community residents in demonstration health centers and general health centers. The sample included 2,261 community residents who were conveniently selected from demonstration (792 participants) and general health centers (1,496 participants). Result: The results of the study were as follows: 1) Perception and participation rates of exercise, nutrition, and hypertension management programs were significantly higher in the participants of demonstration health centers than those of general health centers.; 2) Satisfaction rates of all programs except the smoking cessation program were significantly higher in the participants of demonstration health centers than those of general health centers. However, only the exercise rate among risk behaviors of participants was significantly higher in demonstration health centers than general health centers. Conclusion: Systematic efforts for health promotion were effective not only in improving the community's awareness, participation, and satisfaction of the program, but also in changing health behaviors. This evidence should be used to foster and disseminate health promotion programs toother health centers to improve community residents' health status and quality of life.
