The ozone concentration is one of the important environmental issue for measurement of the atmospheric condition of the country. In this article, two time series ARE models, the direct ARE model and applied ARE model have been considered for analyzing the ozone data at southern part of the Gyeonggi-Do, Pyeongtaek, Osan and Suwon monitoring sites in Korea. The result shows that the direct ARE model is better suited for describing the ozone concentration in all three sites. In both of the ARE models, eight meteorological variables and four pollution variables are used as the explanatory variables. Also the high level of ozone data (over 80 ppb) have been analyzed at the Pyeongtaek, Osan and Suwon monitoring sites.

Appropriate vibration model is required to predict in advance the vibration level of a large vehicle which carries sensitive electronic/mechanical equipments and drives often on the unpaved and/or off-road conditions. Central tire inflation system(CTIS) is recently adopted to improve the mobile operation of military and bulletproof vehicles. In this paper, full vehicle model(FVM) having 11 degrees of freedom and equipped with CTIS has been developed for a large vehicle which has $8\times8$ wheels$\times$driving wheels. Usability of the developed model is validated via road tests for three different modes (i.e. highway, country, and mud/sand/snow modes) and for various velocity conditions. The developed FVM can be used to predict the vibration level of the large vehicle as well as to determine the driving velocity criterion for different road conditions.

Recently, as new paradigm for government operation called government 3.0, government is actively operating policy opening and sharing public data. In addition, the Ministry of Land are operating an open platform integrated map service (the VWorld) which provides a variety of video contents such as the country's national spatial information, traffic information and three-dimensional building for the public. According to W3C Foundation's Open Data Status Report(2013), our country has the evaluated results that the part of the government's policy support and planning is good while the part of the data management is vulnerable. So our country needs the quality improvement for the data management. In addition, a digital aerial photograph image data is required to be up-to-date for the three-dimensional spatial object data. In this paper, we present the method for enhancement of the accuracy of vertical position and for maintainment of up-to-date vertical position. Our methods evaluate the data quality and analyze the cause of error of measurement utilizing the national standard quality assessment method. The result of research shows that the accuracy of vertical position is improved if the height of the building captain is adjusted by the quality assessment values and a three-dimensional model has up-to-date data if reconstruction and extension information of construction register is utilized.

China is the biggest market for the Korean fashion industry. However, China is still difficult in regards to market entry and market success in China despite the geographical proximity. This study investigated the image of Korea and its impact on brand identity, brand attitude and intention to purchase with a focus on Chinese consumers in order to identify the variables of a country's image that affect a consumer's intention to purchase. The results of this survey targeted 214 Chinese consumers who were used for the final analysis. The survey subjects were female consumers in their 20s and 30s, living in metropolitan cities in China. Exploratory factor, reliability and frequency analyses were conducted using SPSS 19.0; in addition, confirmatory factor and path analyses were administered with AMOS 18.0. We identified two general images of Korea (economy and culture), two images of Korean (stylish and friendly) and three Korean fashion-product related images (quality, design and prestige). The results of the structural equation model were as follows. 1) Economy factor exerted significant effect on quality and prestige. 2) Stylish factor exerted a significant effect on all of the Korean fashion product images (quality, design and prestige). Friendly factor exerted positive impact on prestige. 3) All of the Korean fashion product images significantly influenced brand identity. 4) Brand identity exerted a significant effect on brand attitude. Lastly, brand attitude significantly affected intention to purchase.

In this paper I present the framework for programming education relating to the programming course in university. First of all, I identify the literature of the psychological and educational study of programming in domestic and foreign country. Some outstanding papers in foreign country show that the mental model, programming knowledge and strategies are the important difference between novice and expert programmers. And various problems experienced by novice programmers are identified. I summarise this material and suggest some practical implications for programming teachers in their teaching activity. The framework for programming education presented by this work has three dimensions of program development process, programming learning factors and teaching and learning methods for programming to develope the novice's programming skill. It helps the programming teacher to design, implement and evaluate their programming course with the guideline of programming activities.

Objectives: Although compensation for occupational injuries and diseases is guaranteed in almost all nations, countries vary greatly with respect to how they organize workers' compensation systems. In this paper, we focus on three aspects of workers' compensation insurance in Organization for Economic Cooperation and Development (OECD) countries - types of systems, employers' funding mechanisms, and coverage for injured workers - and their impacts on the actual frequencies of occupational injuries and diseases. Methods: We estimated a panel data fixed effect model with cross-country OECD and International Labor Organization data. We controlled for country fixed effects, relevant aggregate variables, and dummy variables representing the occupational accidents data source. Results: First, the use of a private insurance system is found to lower the occupational accidents. Second, the use of risk-based pricing for the payment of employer raises the occupational injuries and diseases. Finally, the wider the coverage of injured workers is, the less frequent the workplace accidents are. Conclusion: Private insurance system, fixed flat rate employers' funding mechanism, and higher coverage of compensation scheme are significantly and positively correlated with lower level of occupational accidents compared with the public insurance system, risk-based funding system, and lower coverage of compensation scheme.

This study aims to analyze the export effects of Korea-Canada FTA's tariff reduction, which was launched on January 1, 2015. First, as a groundwork, this study reviewed trade creation and trade diversion by investigating all possible cases of both initial FTA and additional FTA. The review was done by using the simple model of three countries assuming FTA means elimination of tariff. The review suggested that additional FTA doesn't have any negative impact on import country's social welfare contrary to initial FTA. In additional FTA, Trade diversion could happen between FTA partner countries, but it always increases import country's social welfare. In this sense, it can be called favorable trade diversion. Second, this study analyzed the export effects of Korea-Canada FTA using Clausing's product level model based on Canadian government import data from Korea which is not open to the public. It turned out that Korea-Canada FTA's tariff reduction boosted Canadian import growth rate from Korea. On the other hand, Canadian import growth rate from rest of the world was not negatively affected by Korea-Canada FTA's tariff reduction. Rather, it increased as Canadian import growth rate from Korea was higher. These findings implied trade creation rather than trade diversion of Korea-Canada FTA when it comes to Korea's export to Canada.

This paper is a review of a 13-year-old policy for university reform in Korea, the Brain Korea 21 Program, based on current theoretical frameworks. Current theoretical frameworks are classified into three groups: micro and macro perspectives on universities and discussion on world-class universities. The overall purpose of BK21 is to bring up high-level scholarship through manpower and achieve several targets of university reform. The program can be evaluated as a success in terms of following a research university model but not the entrepreneurial university model. However, the fact that a 13-year old policy developed under a research university model had features of the entrepreneurial university shows the direction of change that the research university is currently undergoing.
