In recent years, behavioral disorders of young people and juvenile delinquency tend to increase remarkably in number, and closed up highly as a social and educational problems in Korea. It goes without saying that parents generally play important roles in children's development of personality, and the home is mostly responsible for juvenile delinquency. Therefore, first this paper describes a relation between broken family and juvenile delinquents. Burt, Shideler, Neumayer, and Glueck maintain that broken family is a cause of delinquency, on the other hand, Healy and Sutherland assume a critical attitude toward their contentions. Second, Breckinridge, Merril, and Glueck maintain that poor family is as cause of delinquency, while Sullenger, Neumayer, and Dirksen make a considerable point which poverty has no direct connection with delinquency. Third, abnormal family relationships namely, discord family, abnormal parent-child relationship, and immoral family exert a bad influence upon formation of personality, esepecialy during the period of preschool childhood. These results give some empirical support to the theory that children's conduct disorders and juvenile delinquency are caused by defective family relationships. It is necessary that a community has a supporting structure of children's wholesome development and the prevention of juvenile delinquency.

The purpose of this study is to investigate how three factors--designer's capability, product market strategy, and product organization--supposed to determine the design process are related to each other. These factors influence Korean knitwear companies' market performances. For this purpose, we did not only library research on relevant theories such as the transaction cost economics but also empirical research largely based on a questionnaire. The respondents of the questionnaire were 59 designers, merchandisers(MDs), and top managers of knitwear companies located in Seoul. We analyzed the collected questionnaire data by using such statistical tools as χ²-test, t-test, and one-way ANOVA. Findings of this study were as follows. While there was a significant relation between organization form and designer's capability, no significant difference in designer's capability was found between trust enhanced network and unenhanced network. No significant relation was found between organization form and product market strategy, in discordance with Carney's arguments. Also, it appeared that there was no significant relationship between knitwear companies' product market strategies and their designers' capabilities.

The fluorescence quenching of 2, 5-di-(5-tert-butyl-2-benzoxazolyl)-thiophene (BBOT) by aniline in five different solvents namely heptane, hexane, cyclohexane, dioxane and acetonitrile has been carried out at room temperature with a view to understand the quenching mechanisms. The experimental results show positive deviation in the Stern-Volmer plots in all the solvents. In order to interpret these results we have invoked the Ground state complex and sphere of action static quenching models. Using these models various rate parameters have been determined. The magnitudes of these parameters suggest that sphere of action static quenching model agrees well with the experimental results. Hence this positive deviation is attributed to the static and dynamic quenching. Further, with the use of Finite Sink approximation model, it was possible to check these bimolecular reactions as diffusion-limited and to estimate independently distance parameter R$^1$ and mutual diffusion coefficient D. Finally an attempt has been made to correlate the values of R$^1$ and D with the values of the encounter distance R and the mutual diffusion coefficient D determined using the Edward's empirical relation and Stokes-Einstein relation.

I present a simple scheme for the treatment of gravitational interactions on galactic scales. In analogy with known mechanisms of quantum field theory, I assume ad hoc that gravitation is mediated by virtual exchange particles - gravitons - with very small but non-zero masses. The scheme predicts the asymptotic flattening of galactic rotation curves, the Tully-Fisher/Faber-Jackson relations, the mass discrepancy-acceleration relation of galaxies, and the surface brightness-acceleration relation of galaxies correctly; additional (dark) mass components are not required. The well-established empirical scaling laws of Modified Newtonian Dynamics follow naturally from the model. The scheme I present is not a consistent theory of gravitation; rather, it is a toy model providing a convenient scaling law that simplifies the description of gravity on galactic scales.

In recent applications, map controlled thermostat has been adapted to optimize engine cooling system and vehicle cooling system. First of all, this strategy is focused on improving fuel consumption rate and reducing emissions, especially unburned hydrocarbon. The object can be obtained through controlling engine metal temperature by varying engine coolant temperature with engine load and speed. To achieve this goal, it is necessary to understand the characteristics of engine metal temperature and heat rejection rate to coolant. From the results of tested engines, it is obvious that fuel consumption rate has more dominant effect on engine metal temperatures than the corresponding engine power does. Also, Re-Nu relation which shows heat rejection rate to coolant in function of air-fuel mixture and engine specifications has been studied. Also, the empirical Re-Nu relation at full loaded engine was developed.

In the IT(Information Technology) service, which supply the solutions related to business management and IT, network construction and application trends, the related service business are increasing according to the enlargement of project scope and the diversity of project types as the need of service customers. In this paper, I propose the significant effect factors on the network management of IT service firms. The key findings are from the analysis result about 94 IT service firms as follows. For implementation the high performance of network management in the IT service firms, the strategic elements in the process of network construction are more conceived highly than the basic element in them. Also the perspective of project objectives are considered than the nominal perspectives in the partner selection process. The competency of partner firms', the cooperation process between the partner firms', network relation operation management and network relation structure management are the significant effect factors of network management.

Recently, many internet users are using mobile music service. In this paper, we aim to examine the effects of system quality factors and relation quality factors on continuance intention in the context of mobile music service. In order to analyze the antecedents of continuance intention, we introduced independent variables such as ease of use, stability, trust, involvement and unity. We also consider customer value and customer satisfaction as mediators. For empirical analysis, we surveyed 240 users of mobile music service. We conduct PLS (Partial Least Square) analysis for SEM (Structural Equation Modeling). As a result, 8 of proposed 12 hypotheses were accepted. Especially, system quality, trust and unity show positive influence on customer satisfaction significantly. Involvement and unity are positively related to customer value. Customer value and customer satisfaction show positive influence on continuance intention significantly. The results of this research can be useful guidelines for mobile music service users and providers.

Rearing is important to the growth and development of the child. Traditionally, nurturing is a maternal role which is expressive role. Maternal role was composed of mothering and maternicity. Rearing is a key concept of psychology, education and sociology discipline. Knowledge of the rearing is an essential component for the development of nursing as a science and a profession. The first thing to study a concept is thought to be a concept analysis. So, in this study, concept analysis of the rearing was performed to clarify a concept of the rearing as a basis for the study of rearing afterward. The approach used for the concept analysis was the approach presented by Walker and Avant (1993). The defining attributes of rearing, identified in this study were (1) a series of caring activities in parent-child relation, (2) an essential of the growth and development of a child, (3) changeable according to time, place and object, (4) effort is necessary to the rearing, (5) positive or negative aspects (6) attitude, behavior, environment is sub-concepts of the rearing concept. The identified antecedents of the rearing was child-birth. The identified consequences of rearing were desirable or undesirable outcomes. Desirable outcome was the emotional satisfaction and growth in parent-child relation. Undesirable outcome was the emotional disorder and social maladaptation of the child. The empirical referents of the rearing could be the caring phenomena in parent-child relation.
