Since the power density of the VHTR(Very High Temperature Reactor) is lower, there is less possibility of core melt. VHTR has no risk of explosion caused by hydrogen generation when the loss of coolant accident occurs, which is another advantage. Along with safety benefit, it can be used as a process heat supplier near demand facilities because coolant temperature is very high enough to be used for industrial purpose. In this paper, we designed the primary system using VHTR and the secondary system providing electricity and process heat. Based on that 350 MW thermal reactor proposed by NGNP(Next Generation Nuclear Part), we developed conceptual model that the IHX(Intermediate Heat Exchanger) loop transports 300 MW thermal energy to the secondary system. In addition, we analyzed thermodynamic behavior and performed the efficiency analysis and optimization study depending on major parameters.

Korean solar energy companies are currently suffering bankruptcy, receivership, liquidation of operation, lay-off or other similar event and most of the conglomerate are also downsized or discontinued operations in the industry. This study aims to assist Korean solar energy companies in making decision to overcome the current industrial crisis through looking into the Korean companies' growth, encounter with the crisis and strategies to survive. The main research topic in this study is a comparison between respective effect of M&A and restructuring on corporate value to understand such effects on solar energy companies. In this study, we utilized a variety of research methodologies, including dummy regression analysis, binary analysis of variance, analysis of cross addition to T-test was carried out empirical analysis. As a result, it seems that the companies who chose an M&A are facing a better situation in terms of survival and market share despite the ongoing crisis. Through this study, it could be found that, for a technology company, an M&A would be a better option than restructuring to grow and overcome a crisis.

In this study, Austrian cleaner production program, ECOPROFIT, was introduced to 15 companies in Korea. The performance and the proposed options of the program were compared with those of Austria. Various options such as good housekeeping, process changes, internal/external recycling, substitution of raw materials were suggested for domestic companies. There are something in common between Korea and Austria such as no relation between company sizes and derived options and good housekeeping as a major option. The difference is that 1.9 years of recovery period on investment is required in Korea, while only 0.5 year is required in Austria. The reason for not applying the suggestions was due to the priority of the company policies in Korea, but was due to the technical problems in Austria. To activate the cleaner production in the Korean regional industry, more systematic analysis on the examples and performances as well as additional studies to disseminate informations and the best practices are necessary.

3D-PTV measurement has been carried out for the inner flows of a refrigerator. To visualize the air flows three-dimensionally, a helium bubble generator has been used for the 3D-PTV measurements. Three-dimensional flow field of the refrigerator's compartments have been reconstructed by the results obtained by the 3D-PTV Measurements on the electric power-consumption was also carried out in order to evaluate the improvements of the flow characteristics. It was verified that $3\%$ of power consumption was saved by improving the flow passages and characteristics.

The aim of this article is to argue that repeated singing helps to feel 'misery loves company.' Folksong is popular music in the past. Korean folk songs have almost repetitive chorus. The repetitive refrain is made easy for everyone to follow. So, people become comrades who share the chorus together. Repetitive music makes people more intimate and more intimate. So, people feel that they share thoughts and feelings with music. It gives me energy to never give in to destiny. So, they encourage each other to be worth living. They sing together and sympathize and comfort each other's pain. 'Hook song' is the most popular form in these days in Korean music. The form of K-pop (Korean pop), which is gaining popularity worldwide, has many repetitions and concentration of melody. BTS (Bang Tan Sonyundan, Boyband) also tells teens around the world through repetitive melodies that "Let's share our joy and sorrow." This is the highest value of music therapy. BTS is a Korean boy band that has gained a worldwide reputation. Recently, their songs are affecting teenagers all over the world. In this way, the author thinks that the repetition of folk songs was reborn as a 'Hook song' and the repetitive form of music is a good way to give support to anyone. The author thinks this is best accomplished by singing 'misery loves company.'

The purpose of this research lies in analyzing the corelation between the eco-friendly management activities of a cosmetic company and customers' decision making in terms of purchase. In this research, 355 copies of questionaire from general customers were analyzed using the statistic package program of SPSS v.18.0. Based on the research analysis, the attributes of eco-friendly management activities can be categorized into three factors such as 'energy saving', 'contribution to communities', and 'environment-oriented services' and have the statistically meaningful positive influence on the three factors of customers' decision making; 'purchasing intention', 'assessment of purchase', and 'repurchase'. This research shows that the eco-friendly management activities of a cosmetic company is an important factor for its successful marketing strategy. This research has a significance in that it has studied the eco-friendly management activities of a cosmetic company through stereotyping. We can expect successful marketing effect if a cosmetic company uses eco-friendly products, information, and services in its eco-friendly marketing.

The purpose of this study is to analysis of counter strategy of greenhouse gas·energy target management system for the construction firm. For this purpose, the greenhouse gas·energy target management system of other industries was investigated. The selection possibility that is construction firm to be managed company was analyzed. In addition, status of counter strategy on the greenhouse gas·energy target management system were investigated and analyzed about 5 domestic major construction firm via questionnaire and interview. As a result, the counter strategy by organization and annual for the greenhouse gas·energy target management system was drawn.

Fatigue life prediction is based on fracture mechanics and database which is established from experimental method. Rubber material also uses the same way for fatigue life prediction. But the absence of standardization of rubber material, various way of composition by each rubber company and uncertainty of fracture criterion makes the design of fatigue life by experimental method almost impossible. Tearing energy which has its origin in energy release rate is evaluated as fracture criterion of rubber material and the applicability of fatigue life prediction method are considered. The system of measuring tearing energy using the principal of virtual crack extension method and fatigue life prediction by the minimum number of experiments are proposed.

Thermomechanical processes were carried out to evaluate their effects on the mechanical and the microstructural property of a ferritic-martensitic steel. Modified 9Cr-1Mo steels were hot-rolled at a temperature of either $780^{\circ}C$ or $850^{\circ}C$ after normalizing at $1050^{\circ}C$ and then were air-cooled. Continuous annealing at $850^{\circ}C$ for 2 hours immediately after the hot rolling was also performed and they were compared to the specimens without thermomechanical process. The result showed that there were little differences between the hot rolled specimens in terms of the precipitation density and size. However, V content inside the MX precipitates increased in the case of the specimen rolled at $850^{\circ}C$. The application of the continuous annealing induced coarsening of the Nb-rich MX precipitation as well as an increase in the amount of V-rich MX precipitation, which is expected to enhance high temperature mechanical properties of the ferritic-martensitic steel.
