Workplace Panel Survey(WPS) is the representative panel survey of workplace in Korea. WPS was newly sampled in 2005 and is to be used for the subsequent biennial survey. The main survey is divided into a questionnaire for human resources(HR) manager, a questionnaire for labor relations manager and a questionnaire for representatives of unions. The population of WPS 2005 included workplaces across the country with 30 or more employees. The WPS 2005 was composed of 1,905 workplaces including 290 workplaces in the public sector. The sample was selected by the stratified random sampling. Weighting process for the survey data was introduced to compensate for differential sampling and non-response rates. Personal interviews were conducted using the Computer Assisted Personal Interviewing(CAPI) system during visits by interviewers, along with survey via mail and e-mail concerning employment and financial issues. The CPAI system introduced for the WPS 2005 can by used for automatical detection for errors and inconsistencies which may occur during the survey process. The CAPI system played an important part in enhancing the reliability of the survey data.

This study set out to investigate the adaptation process and experiential structure of those children who went through sexual abuse by looking into their inner worlds in order to understand what kind of meaning sexual abuse had on them. For that, the investigator conducted in-depth interviews with 13 children aged 8~16 who lived at the shelter after experiencing sexual abuse. The methodology of Grounded Theory by Strauss and Corbin(1990) was used to analyze raw data. The analysis results indicate that the core theme of the adaptation process among the children living at the shelter after sexually abused by kin and kith was "hoping to appear the same as others." According to the results, the core phenomenon was "blaming the victims." The causal conditions include "broken families," "antihuman sexual abuse," "making sexual abuse a public issue," and "the trap of the family." The contextual conditions include "the chain named family," "family as the last fortress" and "structural enforcement of silence." The intervening strategies was "dual emotions toward the shelter." The action/interaction strategies include "aftermath of violence" and "trying to escape." The consequences were "preparation for the future" and "uncertain future." The identified stages include the confusion, keeping the secret, leaking the secret to others, intervention by others, social support and challenge and adjustment stage. The three identified types were "withdrawal and avoidance," "settling down in reality" and "overcoming and challenging." Based on the analysis results, discussions were made about the social welfare plans and intervention strategies in the conclusion.

The purpose of this study is to describe the technologies necessary to design responsive web with the use of the responsive website based on implementation structure as a prototype. Responsive design means the process of analyzing prototype requirements on the basis of implementation and applying the analysis results to development. The design method based on the principle of priority in development was established, and then flexibility and variability through design formula were set up. After that, the user-oriented primary principle and secondary principle were drawn to establish implementation structure. In the way of discussing compression technologies, a method of combination was searched for, and then a method of asynchronous script scalability in line with a web prototype was found. Today, a website or a web application needs to be adopted and accessed regardless of device types. As a solution, a responsive website design method was found. Important technologies for the implementation structure for the responsive website design method and its relevant prototype website were came up with.

It is urgent to systematically understand vocational training and qualification systems in advanced nations in order to evaluate and reform the Korean counterparts. In the British case, the system has been transformed from the market-led one to the state-led one while the German system is still classified as a corporatistic one. This structural difference is crucial to understand their performances and the German one won a relatively more positive evaluation in its performance. However, the structure and function of the German system has lately revealed numerous limitations in face of the political unification and long duration of economic recessions. This study shows that those differences in structural and functional features and recent developments of the systems in two nations are closely associated with their differences in educational philosophies and occupational cultures, roles of the state and employers, and operation mechanisms of training courses and vocational qualifications systems. Understanding those national differences raises a fundamental question on the hasty prescription of some domestic studies that a few policies in the foreign systems must be implanted to reform the Korean counterpart without understanding the fundamental difference between the domestic and those foreign systems.

The purpose of this study is to provide appropriate methodology to ensure the safety and integrity of the production riser in offshore structure. In order to select integrity estimation methodology for production riser, level I and II Non-destructive Damage Evaluation (NDE) methods that were applied to existing structures are classified and reviewed. Numerical analysis is performed to verify the applicability and capability on damage detection of reviewed methods. As a result, the damage detection methodology using modal strain energy is more sensitive in detection of the damage than other methods. In practice, the number of sensors is limited due to the environmental and financial conditions. The impact on damage detection performance by reducing the number of sensors is systematically investigated through a series of numerical analyses and the results are discussed. The optimal number of sensor for the integrity estimation of production riser is recommended.

This thesis discusses the emerging system of value and structure of feeling in today's Chinese society through analyzing Chinese main theme TV series. The 2000s' Chinese main theme TV series represents Chinese's anger and nervousness into the structure of narrative, and they try to form a bond of sympathy with the audience by various characters which represent the common people. Main characters are no longer revolutionists who internalize ideas of socialism and collectivism, but they put emphasis on individuals' thoughts, tastes, and values, and freely express them. Individualism, which was negatively represented and excluded in main theme TV series before 2000s, are compromised and included in today's Chinese dramas. Even though dramas represent the superiority of communism, individuals' choice of various value and faith is positively and flexibly considered. There is a new phenomenon where female figures are no longer passive and dependent, but they are portrayed with given with unique roles and status. Although main theme TV series are directed under the state and government's supervision, they exist in the relation where market, state, drama text, and audience interact.

This study attempts to test the effects of neighborhoods on children and adolescents' alcohol, cigarette and marijuana use. Theoretically, this study was guided by Akers' (1998) SSSL model as potential explanations for understanding the linkage and provided partial test of the model. More specifically, it aims to test the mediation effects of one of core propositions of the SSSL model; whether differential association with deviant peers as well as with conforming peers mediates social disorganization of neighborhoods on adolescent substance and drug use in a different direction. Using multilevel regression techniques with robust standard error, this study utilized data from 1,791 children and adolescents who were nested in 80 neighborhoods in Chicago. The findings of the study provide mixed supports for the SSSL model. That is, it found that there are not only mediation effects but also moderation effects of differential association on children and adolescents' substance and drug use.

Since a distribution market was opened in 1993 after the conclusion of the Uruguay Round (UR), various new businesses emerged in the Korean retail industry, such as convenience shops, supermarkets, specialty stores, non-store marketing methods, and cyber shopping malls, in addition to traditional markets and department stores. Competition among these retail businesses has intensified. According to the National Statistical Office (NSO), the growth rate of the total retail industry has shown a 32% increase in the past 5 years. While department stores, supermarkets, specialty stores, and other non-store retailing venues have shown signs of stagnation at a growth rate of 20-30%, which is similar to the growth rate of the entire retail industry, convenience shops and non-store marketing have shown 60-70% growth over the same period. By comparison, the growth rate of cyber shopping malls has nearly tripled. When applying development aspects of retail businesses through the competition to the retail life cycle, mom-and-pop stores and traditional markets have already entered the decline phase as specialty stores reach their maturity phase and demonstrate their limit of growth. Department stores are now in the latter part of the growth phase, which is still considered to have some growth potential. Big super markets are still in the early part of their growth stage although they were introduced 20 years ago. Meanwhile, retail businesses such as convenience stores, supermarkets, mail order houses, and warehouse stores are entering the middle growth phase and are expected to continue with their quantitative growth. At a time when most retail businesses in Korea are in a state of development or in the full growth stage, what kind of new innovative retailing will appear and develop? Moreover, what growth engine will drive it? This study analyzes the appearance of innovative retailing and its development process by establishing a discussable consumer's choice model through the interlocking mutual behavior of differentiated competitiveness and consumers' choice based on an awareness of this issue. The analysis of the results of this study can be summarized as follows. First, if a new vacuum zone emerges at the retail market level, innovative retailing such as low price/low service or high price/high service will emerge simultaneously. Second, if the number of new businesses in the vacuum zone increases, this will create competitiveness among the businesses, and each retailer will develop raising of level. Third, if a new business that raises the level develops, competition between the new and the existing retailer will occur, and an assimilation process between the existing retailing and the new retailing will be unfolded. Fourth, each retailing will promote distribution innovations in order to break the frontier of the existing distribution technology, and other retailing will follow the innovator. On the basis of an analysis of the abovementioned results, this study presents the following three suggestions. First, responding to the consumer's decision-making process on the attributes of retail shops that promote differentiation in strategies, this study established a consumer's choice model that can be discussed in relation to changes in market share. Second, this study provided an analysis of the emerging and developmental processes of innovative retail businesses using a more precise logical structure on the basis of the consumer's choice model described in this study. Third, the development process of retail businesses discussed in this study presented retailing solutions regarding management aspects on how to compose a strong retail mix that can help retail businesses gain competitive advantages in the market.

This study aims to find an effective way to present essential science concepts in national science curriculum through international comparisons. Next Generation Science Standard (US), Ontario Science Curriculum (Canada), Australia Science Curriculum, and British/English Science Curriculum were selected for comparison. In science curriculum documents, these countries used terms such as 'Key ideas,' 'Big ideas,' 'Key concepts,' 'Disciplinary core ideas.' and 'Fundamental concepts' to present essential concepts of science. This study reviewed the characteristics of the meaning, the status, and the role of essential concepts country by country. The result shows essential concepts have been used with different meanings and statutes in each case. Furthermore, various roles were performed through essential concepts in order to organize their science curriculum. From these foreign nation's cases, this study proposes several ways to present essential science concepts based on results. First, interdisciplinary integrated concepts were needed to organize an integrated science curriculum. In science curriculum documents of the United States, Canada, Australia and England, two types of terms were used in order to structuralize an integrated science curriculum. Second, essential concepts should include concepts related with function and value as well as scientific knowledge. Third, essential concepts need to be presented in such a way as to show specific contexts. Therefore, selecting appropriate contents and structure are needed to be able to improve the way to present essential concepts in Korea's educational environment.
