It is a well-known fact that Internet addiction adversely affects mental health of adolescents. This study was conducted to determine whether there is a difference in the experience of depression according to the level of Internet addiction. Participants included 73,238 middle and high school students from the Korean Youth Risk Behavior Web-based Survey (KYRBWS) conducted in 2010. The level of Internet addiction and the experience of depression were assessed using self-diagnosis questionnaires. Multiple logistic regression analysis was used to identify the association between Internet addiction and depression. High-risk and potential-risk Internet users were 1.61 times and 1.21 times more likely to experience depression, respectively, than normal Internet users. The increase in depression was more significant in girls students. Acknowledging the connection between Internet addiction and depression, the problem should be tackled from the perspective of school health by providing systematic Internet addiction prevention and treatment programs.

This paper presents a methodology of estimating incomplete information in electricity markets for analyzing the gaming behavior of Generating Companies (GENCOs). Each GENCO needs to model its opponents' unknown information of strategic biddings and cost functions. In electricity markets with complete information, each GENCO knows its rivals' payoff functions and tries to maximize its own profit at Nash equilibriurnl Nli) by acknowledging the rivals' cost function. On the other hand, in the incomplete information markets, each GENCO lacks information about its rivals. Load patterns can change continuously due to many factors such as weather, price, contingency, etc. In this paper, we propose the method of the estimation of the opponents' cost function using market price, transaction quantities. and customer load patterns. A numerical example with two GENCOs is illustrated to show the basic idea and effectiveness of the proposed methodology.

This paper discusses global expansion and global strategies of shipping firms. Acknowledging the lack of research on global expansion by freight transport companies, this paper employs the resource-focused model, and explores "why shipping companies emerge" and "why the strategic behaviour of shipping companies is different in the global market". Despite there being a plethora of theoretical and empirical studies on the international operations of business organisations, it is acknowledged that researchers have largely neglected the issues regarding the international expansion within the freight transport industry. Identifying the general lack of contemporary studies concerning the international behaviour of shipping firms, this study addresses the important gap in our knowledge in the theoretical manner. The theoretical analysis suggests that the shipping company's internal resources can be a real reason for the international market participation.

This study was an attempt to present an appropriate way of interpreting L2 learners' linguistic behavior within Universal Grammar (UG) framework. Based on the Korean EFL adult learners' performance on the Subjacency violation sentences, the study suggested that the EFL learners are able to acquire subtle knowledge of target grammar and their linguistic behavior should be interpreted with the most recent version of UG theory, the Minimalist Program (MP) notion. The MP notion seems more plausible to accommodate incomplete L2 grammar while acknowledging UG-constrained interlanguage which the previous version, Principles and Parameters (P&P) approach, could not explain very well. The study observed no age-effects among the Korean EFL learners in their linguistic competence measured by the performance on the UG-constraint violation sentences. Having suggested that the MP notion can be a more reasonable tool to explain the EFL learners' linguistic behavior, the study introduced comprehensive hypotheses such as Constructionist Model (CM) and the Ontogeny Phylogeny Model (OPM).

The Republic of Korea, ranked as the 5th military power according to the size of its ground troops, discharges more than 200,000 manpower to the society annually; more than 13,000 of them are officers. The re-employment rate of discharged military personnels, who experience early retirement of 5 to 15 years compared to general public officers, is very low, only amounting to 53.2%. On the other hand, major developed countries exhibit great national scale of effort to take responsibility in helping the settlement of the soldiers who have dedicated their career for their countries. The re-employment rate amounts to 94%. Fully acknowledging such disparity, this paper examines various policies on discharged members support of developed countries, and aims to suggest developmental model on employment support designed for discharged members in the Republic of Korea.

This case study describes the nature of young children's responses in the informational picturebook reading process through the eyes of 4 young children. Over a twenty week period from September 3, 2007 to February 15, 2008, researcher observed 4 young children while they read informational picturebooks and interacted with one another in terms of what they had read. The young children's personalities, preferences and environments as individual background clearly influenced responses and interaction during the reading process. By acknowledging the response styles of young children, a teacher can assist young children in developing a repertoire of responses to informational picturebooks.

Acknowledging mathematics education as a research field and its relation to different domains such as mathematics, educational sciences, psychology, sociology, and history, two paradigmatic issues of theoretical research and classroom practice are focused on to synthesize the different domains in mathematics education. Six sub-categories in the field of mathematics education are proposed to have a better understanding of their role and interdependence.

Purpose: The purpose of this study was to understand nurses' experience of managing diet and fluid in hemodialysis patients and to provide helpful information in improving care of hemodialysis patients. Methods: Data were collected through in-depth interviews with ten nurses who had experience of providing care to hemodialysis patients. Colazzi's phenomenological method was used to analyze data. Results: Twenty themes were identified in the first stage of data analysis and were later categorized into ten theme clusters, of which four categories were derived. The four categories were 'developing a strong feeling of responsibility for management', 'acknowledging limits in performing duties', 'providing patient-centered education' and 'becoming a guide for the long treatment process'. Conclusion: The study results will be useful for improving nursing curriculum to ensure more effective and successful diet and fluid management in hemodialysis patients.

The Industrial/Technological Cultural Properties are being protected, the rest facing with demolition and damages. In order to better cope with such situation, Korea has officially introduced the Registered Cultural Properties System since 2001 and began acknowledging the historical values of industrial buildings as modern cultural properties. In the Nordrhein-Westfalen, Germany, there are approximately 3,500 industrial buildings under the cultural asset protection and management not only in the Ruhr-region but also state-wide. Among these, this case study focuses on the Hansa Coking Plant, a large-scale Revitalization project to rehabilitate the old industrial complexes and facility buildings that have been shut down on December 15, 1992. Purpose of this study is to analyze main project plans of each facility in the Hansa Coking Plant and to bring out the main features of the plans, so that they can be utilized to find suggestions for Industrial/Technological Cultural Properties Revitalization in Korea.
