On the base of IT growth, competition between countries for preoccupation of digital content market is keen. And it is prospected that the development of digital content industry will be more rapid with the base of telecommunication infra-structure(for example internet, digital broadcasting) which is the main channel for distribution of digital content. The bill of "Act for Development of Online Digital Content Industry", has passed the national assembly jan, 2002, and "Draft Blueprint for Developing Online Digital Content Industry(2003$\sim$2005)" was made on the base on that law feb, 2003. And we can find measures for protect the digital content manufacture in the laws such as "Literary Property Law", "Trademarks Law" and "law for prevention of unfair competition". On this study we suggested three measures to make digital content industry more profitable by the method of research of related law and industry survey.

The purpose of this study was to examine the developmental trajectories of adolescents' internalizing problem behaviors. The data came from 3,188 middle school students through their participation in the Korea Youth Panel Survey(KYPS). Adolescents with a high level of internalizing problem behaviors in the first year showed a rapid decline in these behaviors over time, whereas for adolescents with a low level of these behaviors in the first year the decline was slow. The predictors of the developmental trajectories were related to individual variables, such as gender, self-esteem, self-control, stress, self-stigmatization, and academic achievement. The developmental trajectories of adolescents' internalizing problem behaviors were classified into four groups. The predictors of the patterns of developmental trajectories in adolescents' internalizing problem behaviors appeared to be related to individual variables.

This paper surveys consumer policies for the internet transaction in the developed countries. Recently the internet transaction has been witnessing a remarkable change represented by the rapid spread of "revolution of distribution". It cannot be, however, stated that internet transaction will dominates all the market places without enhancing consumer's reliability in the internet transaction. Many countries made an efforts to the consumer protection in order to develop infra-structure of information industry. We will soon discover a new paradigm that consumer protection is not a tool for development of cyber market but the goal itself. We survey the process of consumer policies discussed in the developed countries and study the point of prevailing arguments of the consumer protection in the internet transaction. The arguments discussed in OECD meetings are debatable, especially, to the degree of government intervention in the field of consumer protection between EU and US. In contrast of US insisted on the minimum intervention of the government, EU suggest the opinion of more aggressive role of government in consumer policy in the cyber market. This paper attempts to provide several guide lines of Korean consumer policy in the cyber market.

This paper explores the causal relationship between acceptance attitudes and expected effects of smart work. With the rapid development of smart technologies, lots of organizations try to innovate in the conventional working styles for maximizing organizational effectiveness and efficiency. Although many organizations wish to foster smart working environment, they don't have confidence in detailed action plans and effects from it. Therefore, this study that explores the causal relationship between acceptance attitudes and effects may have crucial meaning to organizations pursuing smart work. In this research empirically conducted by questionnaire survey, the acceptance attitudes as predictors and the expected effects of smart work as influenced variables were used. This research analyzed 118 collected data and multiple regression analysis. As a result of analysis, teleworking shows the positive relations to all of dependent variables. And others have a positive or negative influence on effects of smart work. Results of this study may give implications to organizations that want to implement smart work environment.

We need to make the standards of maintenance information for urban transit to reduce the cost to maintain the information and to share the information with maintenance workers. It is enable to do systematic maintenance for urban transit by using the information system based on the standardized information. In this paper we propose the major items to standardize and the methods to lay out the standard schemes to enable structured maintenance. We present the 4 items, bill of material, material classification, accident/fault classification, electronic document, to standardize. And we propose how to implement the information system for urban transit based on the standardized information. We describe the implemented information system in two parts; a rolling-stock and an infrastructure part. And also we describe the result of survey to evaluate the system installed at Seoul Metro and Seoul Metropolitan Rapid Transit.

Water quality of the Hwanggujicheon is poor because of the rapid housing and development in the large area of the basin. Establishment of water quality management strategy, based on the pollution sources survey and pollutant loads estimation, has to be established for the preservation of the stream water quality of the region. In this study, waste load allocation model to achieve the water quality goal of the stream and the optimization of pollutant load reduction, was developed. Nonpoint pollutant loads calculated by runoff model in the previous study are utilized for pollutant loads estimation of the drainage areas in this study. From the application result of the allocation model, water quality goals of the Hwanggujicheon that can be achieved as a matter of fact are BOD 8 mg/L. To achieve these goals, 23% of effluent BOD loads have to be reduced in the basin.

We searched for X-ray emission from the 665 galaxies inside and towards the nearby voids by analyzing the ROSAT All-Sky Survey (RASS) data as well as the ROSAT pointed observations (PSPC). As a result we have detected six X-ray emitting galaxies. Two (UGC 10205 and NGC 7509) are in the high density region in the local void, three (UGC 749, MCG +11-10-073, and Mrk 464) are towards the nearby voids, and UGC 32 is located in the low density region. We carried out a timing analysis for both Mrk 464 and UGC 32, and a spectral analysis for Mrk 464. The light curve of Mrk 464 shows the possibility of periodic X-ray flux variation and UGC 32 shows weak, but rapid variation.
