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.

In this paper, the result of an ultrasonic performance demonstration are analyzed. The requirements for an ultrasonic performance demonstration (PD) for a nuclear power plant were first described in ASME B&P Code Section XI, Appendix VIII (1989 winter addenda). In order to establish the performance demonstration scheme in Korean nuclear power plants, the Korea Hydro & Nuclear Power Co. Ltd (KHNP) has developed the Korean Performance Demonstration (KPD) system for the for the ultrasonic examination of nuclear power plants. An analysis of the ultrasonic performance demonstration results from 2004 through 2013 will improve the detection of flaws in an ultrasonic examination, as well as the further development of the KPD training system.

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.

A new type qf demonstrations in the temporal and spacial aspects, such as accidental and unprepared demonstration, urgent assembly, demonstration-on-sea, demonstration-on-highway, and etc., which are not intended in the Law of Assembly and Demonstration, are becoming a social problem Especially, the law on demonstration-on-sea needs to be discussed further because it is not clear if the Law of Assembly and Demonstration is applicable here. If so, how can it be explained logically? Or, if not so, which law should be applied to this context? So far, various theories on demonstration-on-sea have been opposed aggressively vs. submissively. However, it should be guaranteed that the demonstration on sea is one of the constitutional rights based on the self-decision right of demonstration's place. Accordingly, these contents have to be interpreted with a concept of demonstration in Demonstration's law in coordination with the Constitution. Therefore, it is not persuasive that Demonstration's law is analogized, or general police law is applied, to such untypical demonstrations. In addition, taking into consideration a demonstrative function for minority under modem situation of demonstration, it is right to apply the Law of Assembly and Demonstration to the demonstration-upon-sea directly.

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.
