  • Purpose - The purpose of this research was to examine the regulation and distribution channel of second-hand goods in cross-border trade in order to propose methods of protecting consumers through the international standardization of the intensifying second-hand trade and resource recycling. Research design, data, methodology - This study first defines several concepts relevant to research in international second-hand goods. Second, a questionnaire and interviews were conducted with manufacturers of second-hand toner cartridges and automobile parts to identify the current status of export and manufacturing. Results - The study proposes the international standardization of second-hand goods and waste to protect consumers and promote efficient resource recycling. Conclusions - The results of the study reveal that second-hand goods (except automobiles) do not have an HSK code to use for import/export data collection. Though used car exports are declining, used cars are increasing. Collecting data on used car parts is impossible because the buyers purchase and ship the second-hand parts.

  • For small sized companies in Korea, it is crucial to have a systematic way of collecting and storing quality data, and extracting relevant information when necessary. This paper Is concerned with developing a quality information system which is mainly focused on processing quality inspection data, converting the data into meaningful quality information, and illustrating a case study of a small sized company in Gyeongnam province. First, we review the current quality Inspection system and reorganize a quality system which is more efficient than the current one. Second, incoming material, process, and product inspection modules are developed. Finally, a statistical process control module is integrated to see the manufacturing process behavior over time.

  • The amount of incident solar rays on inclined surfaces with various directions has Since the atmospheric clearness index is main factor for evaluating atmosphere environment, it is necessary to estimate its characteristics all over the major cities in Korea Peninsula. We have begun collecting clearness index data since 1982 at 16 different cities in South Korea and estimated using empirical forecasting models at 12 different stations over the North Korea from 1982 to 2006. This considerable effort has been made for constructing a standard value from measured data at each city. The new clearness data for global-dimming analysis will be extensively used by evaluating atmospheric environment as well as by solar application system designer or users.

  • Nowadays, owing to the development of techniques for collecting geographic information, an increasing need is thus appearing: integrating heterogeneous databases. This paper proposes an algorithm for finding matching relationship between two node sets in road network data. We found the corresponding node pair using link shape linked with them as well as their location. The accuracy of matching was grown by this process. Result then can be used to reflect the topological information in performing link matching.

  • The purpose of this research are (1) determining the basic concepts of clothing field which are included in the middle and high school home economics education curriculum ; (2) comparing the extent of need to those three groups; (3) classifying the basic concepts into units; (4) ana-lyzing the extent of need by units and providing basic data for curriculum revision. The data collecting methods of this research is questionair and the contents of this are the same. The subjects are 1085 students, 402 teachers and 80 professors. The data was analyzed by one-way ANOVA, scheffe test and factor analysis. The results were as follows: (1) 43 basic concepts were determined. (2) While the extent of need in the teachers and professors was high, that of students was me-dium or lower than the other two groups. (3)The extent of need to 40 concepts among three groups were significantly different. (4)According to the results from the factor analysis 7 units were formed. (5)‘Accurate dressing’was the most needed thing among three groups.

We have begun collecting clearness index data since 1982 at 16 different cities and considerable effort has been made for constructing a standard value from measured data at each city. The new clearness data for global-dimming analysis will be extensively used by evaluating atmospheric environment as well as by solar PV application system designer or users. From the results, we can conclude that 1) Yearly mean 61.9% of the atmospheric clearness index was evaluated for clear day all over 2) A significant difference of atmospheric clearness index is observed between 1982-1989 and 1990-1997, 1998-2005 through 16 different cities in Korea.

  • This study provides empirical evidences for the relationship between income inequality and economic growth, and relationship of income inequality with some of explanatory variables such as technological innovation, trade globalization, financial globalization and fiscal policy. We find out that income inequality has an adverse effect on economic growth, showing its dynamic features, for which we employed the polynomial distributed lags (PDL) model. The effect of income inequality on economic growth lasts over 9 years, and its dynamic effect peaks after 4 years. In addition, we also attempted to find out empirical evidences of sources of income inequality. The results show that income inequality is positively related to technological innovation, financial globalization, and fiscal policy; negatively related to the trade globalization. Many studies employ cross-country data, but it could have serious problems in collecting statistical data. Korean data is used over the time period of 1990-2015 in this study.

  • This study is to provide the useful data for the design and construction of the geotechnical engineering works by collecting and analyzing the soil properties of granite soil in the Kangwon Province. Data base was obtained from 92 field sites in the Kangwon province divided into 15 areas based on administration district. Total numbers of data were 478. Correlations between soil constants, especially compaction properties, were obtained by performing statistical analysis. Analyzed results were as follows. 1. Most of granite soil consists of SM and GM based on United Soil Classification System. 2. Mean gravity of granite soil is 2.65 3. High correlations between optimum moisture content and the maximum dry density, plasticity index and liquid limit are obtained. 4. Analyzed results between other soil constants show relatively low correlation. However, they show consistent trends matchable to geotechnical engineering senses.
