The purpose of this study was to investigate the effects of the hair style, and perceiver's generation on the perception of a high schoolgirl's image. A quasi-experimental method by questionnaire was used. The subjects were 253 high schoolgirls and their mothers living in Jinju. The data were analyzed by using frequency, factor analysis, Cronbach's alpha-reliability coefficient, three-way ANOVA, and Duncan's multiple ranges test. The high schoolgirl's image was derived in five dimensions by factor analysis: schoolgirl look, prettiness, individuality, activeness, and cuteness. In the image based on the hair length, it was assessed that the short cut and the bobbed hair styles looked more like school girls. And the short cut and long hair styles were considered as showing individuality. On the other hand, the bobbed hair style was assessed as cuter than styles of other lengths. For the bangs, the short bangs were found to more school-girl look and cuter than the long bangs. The mother group, whose ages were older than that of the other group, evaluated that the stimulative pictures had more school-girl look, individuality, prettiness, activeness and cuteness, compared to how the school girl group evaluated. It was shown that the generation gap produced different opinions about the stimulative pictures. Therefore hair style, bangs style, and difference in generations were found to be the variables affecting perception of high school girl image.

This study was carried out to evaluation of biomass generation mechanisms and to propose the estimation method of biomass generation. Agricultural by-product biomass is generated during crops cultivation and after harvest. However these are not uniformly generated yearly and these depending on the seasons. For planning of biomass utilization, accurate information of the biomass resources is needed, especially characteristic and productivity of biomass are necessary. Agricultural by-product biomass are generated in a wide area being scattered and it is one of the major reason why agricultural biomass utilization is not activated compared with other waste biomass. In this study, estimation and evaluation biomass generation is achieved in specific spatial and temporal boundary, A-city in Gyeongi-do and september to November respectively. Quantity and quality of by-product biomass show big difference depending on the crop species and cultivation periods and these difference bring up that accurate biomass estimation should be considered during planning of biomass utilization and technology selecting for biomass converting to energy and other forms.

Purpose - This study aims to examine differences in donation behavior as surrogates of prosocial consumption behavior among three generation types. Further, it attempts to examine the moderator roles that affect donation behavior influenced by the difference in generations. Research design, data, and methodology - This study used the statistical ANOVA technique to examine generational difference. Surveys were structured differently by ages, as 20th, 30th, 40th, 50th, 60th, and 70th to classify generations into each group. A survey to measure the psychological distance was performed to identify whether the respondents intended to donate to a domestic or overseas target. Results - First, subjective judgment of psychological distance has no effect on objective donation behavior. Second, though the result of the relationship with moral identity is not statistically significant, it provides evidence that a higher moral identity level possesses more donation behavior. Further, groups with higher symbolization tend to donate more than the others. This was especially evident among the young and baby boomer generation. Conclusion - This empirical study suggests that marketers need to differentiate the market segment of the baby-boomer generation with high purchasing power of prosocial consumption.

Recently, renewable energy has been increasing in Korea to reduce greenhouse gas, and solar power generation, which accounts for the largest proportion of renewable energy, is noteworthy. The government policy will further increase solar power generation. In order to implement the policy, it is important to understand the current status of domestic solar power generation facilities. Therefore, the current status of solar power generation facilities in Jinju city close to the south coast and Jeonju city close to the west coast was investigated and compared. By 2020, 618 solar power plants had been installed in Jeonju city and 269 in Jinju city. However, there is not much difference in the amount of solar power generation for business at 9 GWh. The reason is that Jinju city has a lower population density than Jeonju city, so there are enough places to install a large-scale solar power facilities with a large power generation capacity. Monthly solar power generation was the highest in April in both Jeonju city and Jinju city and the lowest in January. In particular, in December, Jinju city showed more solar power generation than Jeonju city because of the large amount of insolation, long sunshine hours, and few clouds.

How to maintain the optimal electric power generation mix is one of the important problems in electric power industry. The objective of this study is to develop a computer model which can be used to forecast the investment in power generation unit by the plant owners after restructuring of electric power industry. Restructuring of electric power industry will make difference in decision making process of investment in power generation unit. After Privatiazation of Power Industry, Gencos will think that profit is the most important factor among all others attracting the investment in the industry. Coal power generation is better than LNG CCGT in terms of profit. However, many studies show that LNG CCGT will be main electric power generation source because the rest of factors other than profit in LNG CCGT are superior than Coal power generation. Because the nst of factors other than profit in LNG CCGT are superior than Coal power generation. The impacts of the various government policies can be analyzed using the computer model, thus the government can formulate effective policies for achieving the desired electric power generation mix.

Ginseng treated with several treatment conditions of various acids to search hydrolysates on the basis of increased biological activity and modified structure. In the result of acid treatment, the conversion rate of ginsenoside Rg3, Rk1 and Rg5 was highest when ginseng treated with citric acid. After added citric acid to ginseng extract, boiled at l00$^{\circ}C$ for 1 hour and add enzyme, which is examined change by time. It compared with group which did not treated acid. Two groups became difference according to enzyme but the generation rate of ginsenoside Rg3, Rk1 and Rg5 did not show difference greatly. Also, the generation rate of ginsenoside Rg3, Rk1 and Rg5 by time passes did not show difference. The generation rate of ginsenoside Rg3, Rk1 and Rg5 increased when increased acid concentration, temperature and time. We did exclusion molding to shorten treatment time. In the result of ginseng treated with citric acid of various concentrations at various temperatures as time passes by extrusion molding, the generation rate of ginsenoside Rg3, Rk1 and Rg5 was highest when ginseng treated with 3% citric acid at l60$^{\circ}C$ for 20 minutes. In addition, total saponin amount of ginseng treated with 3% citric acid at 160$^{\circ}C$ for 20 minutes was about 11% higher than ginseng heated at 120$^{\circ}C$ for 3 hours. These results indicated that our exclusion molding process more effective, compared to traditional red ginseng manufacturing process.

The Potential Induced Degradation(PID) in PV module mainly affected by various performance conditions such as a potential difference between solar cell and frame, ambient temperature and relative humidity. The positive charges as sodium ions in front glass reach solar cell in module by a potential difference and are accumulated in the solar cell. The ions accelerate the recombination of generation electrons within solar cell under illumination, which reduces the entire output of module. Recently, it was generally known that PID generation is suppressed by controlling the thickness of SiNx AR coating layer on solar cell or using Sodium-free glass and high resistivity encapsulant. However, recovery effects for module with PID are required, because those methods permanently prevent generating PID of module. PID recovery method that voltage reversely applies between solar cell and frame contract to PID generation begins to receive attention. In this paper, PID recovery tests by using voltage under various outdoor conditions as humidity, temperature, voltage are conducted to effectively mitigate PID in module. We confirm that this recovery method perfectly eliminates PID of solar cell according to repeative PID generation and recovery as well as the applied voltage of three factors mainly affect PID recovery.
