This study investigates the effects of parent-adolescent communication, adolescent self-esteem, and strategies in peer conflict situations on the satisfaction of adolescents with their peer relationships. The subjects included students attending a girls' and a boys' middle school in Gongju City. Random sampling was used to pick a class from each of the three grades in the schools. 233 students, who's both parents were living, were used in the final analysis in an effort to examine the impacts of student communication with parents on student satisfaction with their friends. The findings were as follows: the subjects most often used the yielding type of conflict-resolving strategy, followed by the cooperating, compromising, dominating, and avoiding strategy-type. The girls showed a higher level of parent-child communication than the boys. Girls had high self-esteem and mostly adopted the cooperating type of conflict-resolving strategies, followed by the yielding, compromising, dominating and avoiding strategy-type. The boys mostly employed the yielding strategy type followed by the cooperating, compromising, dominating, and avoiding strategy-types. The results indicate that the satisfaction level with friends was high among those who used the avoiding strategy-type less and yielding strategy-type more. Girls were found to have high self-esteem and engaged in communication with their parents. The compromising, cooperating, and dominating types of conflict-resolving strategies did not exercise significant influences on their satisfaction with friends.

This feeding experiment was conducted to investigate the effects of slurry type diet on growth performance and survival rate of growing leptocephalus, eel larva. We need to find new materials of diets for rearing eel larvae. Test diets were formulated with the eggs of the shark, fish soluble concentrate, soybean peptide and fish protein hydrolysate. Fish (average length 6 mm) were fed 3 slurry type diet(A, B and C) based on shark egg for 5 times per day. During feeding experiment, survival rates were significantly different among 3 slurry type diets. Total protein, lipid, moisture, ash and free amino acids contents were analyzed for slurry type diets. Leptocephalus fed the C slurry type diet was grown up to $38.0{\pm}9mm$ at 150 days. But all leptocephalus fed B slurry type diet were died at 100 days, reaching $16.4{\pm}8mm$. This results suggest that basic information for diet development of eel leptocephalus.

The hazardous enterprise has been increasing its relative importance day by day in the economy of our country and the world. However, it's mostly true to have been relatively neglected in the field of technical strategy. This is to provide for methodological frame about the research in this field in the future by researching on what kind of technical and marketing strategies make what kind of effect on the result of hazardous enterprise together with the strategy for success by meeting the necessity of this research. Therefore, the individual variable within this research was divided into three parts like technical strategy, marketing strategy and industrial environment. It used the type division of venture-company(High-tech type, Superior enterprise type, Boutique type, General enterprise type) as a controllable variable and the result of hazardous enterprise as a subordinate variable. The result of this research is that the technical strategy of hazardous enterprise has lots of possibilities to raise the financial result if it raises technical reform and supplementary character and technical integration level in case that newly-established hazardous enterprise with relatively lower capital power than big enterprise pursues technical strategy.

This study integrates personality trait theory to empirically Investigate the corporate strategy in Korean venture firms. This study predicts that type A/B, locus of control(internal/external), and risk-taking/avoiding will be positively associated with corporate strategy selection. Corporate strategy selection consists of aggressive entry strategy and defensive niche market strategy. Data obtained from a survey of 87 venture business firms is used to construct final variable measures and test the hypothesized relationships. The statistical result shows that type A, internal, and risk-taking CEOs positively associated with aggressive entry strategy, and type B, external, and risk-avoiding CEOs positively associated with defensive niche market strategy. Additional analysis(multiple regression model) to test relatively importance of independents is used.

This paper proposes a novel compound-type hybrid energy storage system (HESS) that inherits the unique advantages of both battery/supercapacitor (SC) and the SC/battery HESSs for electric vehicles (EVs). Eight operation modes are designed to match this system. A mode control strategy is developed for this HESS on the basis of these modes, and five classes of operation modes are established to simplify this strategy. The mode control strategy focuses on high operating efficiency and high power output. Furthermore, the compound-type HESS is designed such that the SC is the main priority in braking energy absorption. Thus, this HESS can operate efficiently and extend battery life. Simulation results also show that the compound-type HESS can not only supply adequate power to the motor inverter but can also determine suitable operation modes in corresponding conditions. Experimental results demonstrate that this HESS can extend battery life as well. The overall efficiency of the compound-type HESS is higher than those of the battery/SC and the SC/battery HESSs.

The purpose of this paper is study the sensitivity analysis of matrix game. Teh sensitivity analysis of matrix is classified into two types. Type one is to find the characteristic region of an element of the pay off matrix in which the value of the current optimal strategy remains as an optimum. Type two is to find that in which the basis of the current optimal strategy does not change. This paper shows the characteristic regions of basic and nonbasic strategies. Further it is found that the characteristic regions of type one and two are same in the case that the element is that of at least one player's nonbasic strategy.

This study is to review the attitude of consumers on the crisis response strategy (defensive vs. receptive) that the company implements in crisis situations. Also, the interaction between the crisis response strategy that the company implements and the crisis type of companies (corporate ability vs corporate social responsibility) was discussed. In addition, the interaction between the messages (abstract vs. concrete) of public interest associated marketing implemented prior to crisis situations and the crisis response strategy implemented after crisis situations was discussed. And these results were reviewed to see if the same result can come out after controlling the involvement on consumer's public interest associated marketing as a covariate. The main results of this study are as follows. First, regarding the crisis response strategy, in the company's crisis response strategy, the receptive attitude was more favorable for the consumer's attitude than the defensive attitude. Second, it was seen that there is a significant interaction between the crisis response strategy of companies and the crisis type of companies. Third, it was seen that the crisis response strategy of companies has a significant interaction with the message type of public interest associated marketing. Lastly, the involvement showed a significant effect as a covariate and the interaction between the crisis response strategy of companies, the crisis type of company and the message type of public interest associated marketing can be confirmed even after controlling the involvement. In the conclusion of the study, the direction on implications, limitations and future.

In this paper, a new power control strategy for the bipolar-type low voltage direct current (LVDC) distribution system is being proposed. The dc distribution system is considered as an innovative system according to the increase of dc loads and dc output type distribution energy resources (DERs) such as photovoltaic (PV) systems and energy storage systems (ESS). Since the dc distribution system has many advantages such as feasible connection of DERs, reduction of conversion losses between dc output sources and loads, no reactive power issues, it is very suitable solution for new type buildings and residences interfaced with DERs and ESSs. In the bipolar-type, if it has each grid-interfaced converter, both sides (upper, lower-side) can be operated individually or collectively. A complementary power control strategy using two ESSs in both sides for effective and reliable operation is proposed in this paper. Detailed power control methods of the host controller and local controllers are described. To verify the performances of the proposed control strategy, simulation analysis using PSCAD/EMTDC is being performed where the results show that the proposed strategy provides efficient operations and can be applied to the bipolar-type dc distribution system.
