Quantile regression proposed by Koenker and Bassett (1978) is a statistical technique that estimates conditional quantiles. The advantage of using quantile regression is the robustness in response to large outliers compared to ordinary least squares(OLS) regression. A regression tree approach has been applied to OLS problems to fit flexible models. Loh (2002) proposed the GUIDE algorithm that has a negligible selection bias and relatively low computational cost. Quantile regression can be regarded as an analogue of OLS, therefore it can also be applied to GUIDE regression tree method. Chaudhuri and Loh (2002) proposed a nonparametric quantile regression method that blends key features of piecewise polynomial quantile regression and tree-structured regression based on adaptive recursive partitioning. Lee and Lee (2006) investigated wage determinants in the Korean labor market using the Korean Labor and Income Panel Study(KLIPS). Following Lee and Lee, we fit three kinds of quantile regression tree models to KLIPS data with respect to the quantiles, 0.05, 0.2, 0.5, 0.8, and 0.95. Among the three models, multiple linear piecewise quantile regression model forms the shortest tree structure, while the piecewise constant quantile regression model has a deeper tree structure with more terminal nodes in general. Age, gender, marriage status, and education seem to be the determinants of the wage level throughout the quantiles; in addition, education experience appears as the important determinant of the wage level in the highly paid group.

There is an expanding global network of free trade agreements (FTA). High-quality, comprehensive free trade agreements play an important role to support global trade liberalization and are explicitly allowed under the World Trade Organization (WTO) rules. An FTA is an international treaty that removes barriers to trade and facilitates stronger trade and commercial ties that contribute to increased economic integration between participating countries. Korea benefits from the global FTA trend; however it has started and developed FTA negotiations later than other countries. Current FTA agreements exist with Chile, Singapore, EFTA, ASIAN, India, EU, Peru, USA, Turkey, Australia, and Canada; in addition, there are ongoing negotiations with China, Colombia, New Zealand, and Vietnam. FTA open up opportunities for the textile/clothing industry to expand businesses into key overseas markets. FTA improve market access across all areas of trade to help maintain and stimulate the competitiveness of textile/clothing firms. This study examines the expansion of free trade agreements in light of changes in the international trade environment and the status of the Korean textile/clothing industry. Korea's textile/clothing export/import products and concession of tariff, country of origin covered under Korea-US/China FTA are investigated to identify problems. This study provides practical and policy implications for the textile/clothing industry in regards to the Korea-US/China FTA.

This study examined the changes in the service mix of Korean hospitals in 6 metropolitan cities between 2003 and 2005, and assessed whether the sample hospitals exhibit consistent trend or chance variation in multiple years. Three measures of hospital service mix, focusing on the specialization of services, were applied: information theory index, internal Herfindahl index, and number of distinct diagnosis-related groups (DRGs) treated. National Health Insurance claims were used to calculate the indexes. Specialization indexes were calculated in each year, and then examined to identify the pattern over time. Kappa analysis was applied to assess the agreements of specialization score between two years after hospitals were categorized into 4 groups with quartiles. Kappa score showed that the service mix of hospitals were changed during the study years. Specialization scores were increased given the market structure for three years. Hospitals which showed higher or lower specialization scores than the average of the scores consistently classified into the same group. Specialization indexes showed relatively consistent pattern over 3 years, and such consistencies were evident for hospitals regardless of the specialization status. Policy makers can identify the degree of specialization with the indexes, and it could provide a picture of how hospital services were mixed and changed over time.

Since the introduction of new health technology assessment in 2007, benefit coverage process of health insurance related to new health technology has become an upgraded system through the evidence-based decisions. As a result of enforcing this system for 10 years, however, there have been several rising concerns. It needs to support the insufficient evidence of medical technologies, introduce reassessment system for post management of market entry technologies, and improve evaluation methods and process. In addition, there is the possibility of emerging an unheard-of medical technology, fused various categories like artificial intelligence, robot, information technology, physics and life science in the fourth industrial revolution. Now, new updated system introduced to improve new technology assessment, such as 'limited health technology assessment system,' 'system for postponement of new health technology assessment,' 'one-stop service system,' and 'integrated operation of approval for medical devices and new health technology assessment.' Therefore it needs to prepare the improvement plan for new health technology assessment to be established more advanced system, and we have to resolve concerns by communication with various healthcare experts and patients now and for ever.

This study examined the actual consumption status and consumer preference for juk via questionnaire survey to provide useful basic data for the development of diversified commercial juk products. The survey data were collected from a target number of 450 participants living in the Seoul area. The subjects represented different age groups (over 20 years old) and both genders. Through a market survey based on five different retailers, which included juk-specialty stores, supermarkets, and local shopping marts, 17 kinds of commercial juk were chosen for the survey. Consumption frequency and purchasing factors were examined, along with preferences toward commercial juk products and areas for quality improvement. The results revealed that 54.0% of the respondents consumed commercial juk, and male consumers exceeded female consumers in number. It was also shown that those in their $20^{\circ}{\O}s$ consumed commercial juk products the least as compared to other age groups. With regard to commercial juk preferences by type of production mode, females especially preferred specialty store juk while males preferred retort juk sold in supermarkets or local shopping marts. In addition, 85.7% of the total respondents indicated that commercial juk should be further improved in quality, and they specifically noted possible improvements in the areas of 'choice diversification' and 'healthy juk' products. Therefore, one can conclude that by making such improvements, increase in consumption and further diversification of commercial juk products could be realized.

This research was conducted to examine coffee shop customers' preference and satisfaction by different types of promotion. Research samples ware adults with experience of any form of coffee shop promotion (n=209). Descriptive statistics, Chi-square, t-test and one-way ANOVA were used to analyze the relations among variables. Results showed that 'free coupon' was the most preferred ones. SNS was the most frequently used search method for coffee shop coupon promotion information. The most preferred event promotion was 'freebies', and preference levels were significantly different by age and employment status. 'Barista experience' was ranked highest in preference among cultural experience events. Drinking coffee was the most important purpose of visiting coffee shops, especially among unemployed, twenties, and women respondents. Coupon was evaluated the highest in usefulness and satisfaction among the three promotion methods. Event and cultural experience were preferred more by respondents in their twenties than those in their thirties. Results indicated that all promotion strategies are effective for increasing customer satisfaction and for inducing revisit. Findings also showed that preference for promotion was affected by customer characteristics such as age and gender. Therefore, coffee shops should consider using the most effective and attractive promotion strategy for their target market, while maintaining a consistent service quality level to fulfill customer expectation.

Aflatoxin M1, ingested as aflatoxin B1 via contaminated feedstuff and later converted into, is a major problematic target for milk safety control among the aflatoxin class. Korean government has controlled level of AFM1 in milk at 500 ppt as maximum residue level (MRL), and more recently, government also publicized the proposal for more strict control on fungal toxins about infant and baby foods. In this study the levels of Aflatoxin M1 (AFM1) of 42 marketed milk samples were determined with Enzyme-Linked Immunosorbent Assay (ELISA) to evaluate the status on the contamination of Aflatoxin M1. The evaluated ELISA performances of limit of detection (LOD) and the half maximal inhibitory concentration ($IC_{50}$) were 5 pg/mL (ppt) and 49 ppt, respectively. In all 42 samples, AFM1 appeared above the 5 ppt, with the average of 21 ppt and the range of up to 90 ppt. Only 3 (7%) of samples showed the level of contamination above the EU MRL (50 ppt). Although there was incidence of higher level of contamination compared with previous reports, the result of this study requires more intensive study to control of AFM1 in milk and infant foods.
