Objective: The purpose of this study was to compare eating habits and parenting about eating habits of the elementary schoolers in two regions, Seoul and Gangwon-do, in order to understand regional differences. Methods: The respondents of this study included 365 pairs of children and their mothers (150 pairs from Seoul and 213 pairs from Gangwon-do). Data was collected using a structured questionnaire from July to August, 2013. Results: Perceived body type, weight control, and eating habits were significantly different in two regions. Children's eating habits were significantly different by their perception of health status and body type. Their mother's parenting attitude toward eating habits was significantly different by children's weight control and mother's and children's perception of body type. Parenting attitude toward eating habits was not different between two regions by their mothers. eating habits and parenting attitude toward eating habits were significantly correlated. Conclusions: Health provider should consider regional difference when designing health promotion program for elementary students. Especially, when practicing eating habits related program, parents should be participated from the planning stage and provided with the information of the proper body image and weight control.

The purpose of this study was to investigate the satisfaction on the Gwangju Kimchi Festival. The results of this study were as follows: In terms of satisfaction on 'pre event publicity of the Festival', the satisfaction of '03 was high. It was founded that Publicity through TV was successful. The visitors' satisfaction on understanding regional cultures was low. It was consecutively low for three years. There should be strategic development plans to increase satisfaction about understanding regional cultures. It was found that TV was the major pre event information resource for the residents. Also word of mouth was the most important pre event information resource for domestic tourists. The satisfaction on access to festival was increased consecutively. Providing free shuttle buses to the festival place and placing festival placard influenced positively. There should be expansion of service facilities. There should be more strengthening of festival information services and guiding facilities. More professional interpretation systems and interpretation education are necessary. Visitors satisfied about festival products and quality of the products. Visitors satisfied with festival events programs and hands on experience based programs including making diverse Kimchi.

In the present work, spheroidization of angular vanadium powders using a radio frequency (RF) thermal plasma process is investigated. Initially, angular vanadium powders are spheroidized successfully at an average particle size of $100{\mu}m$ using the RF-plasma process. It is difficult to avoid oxide layer formation on the surface of vanadium powder during the RF-plasma process. Titanium/vanadium/stainless steel functionally graded materials are manufactured with vanadium as the interlayer. Vanadium intermediate layers are deposited using both angular and spheroidized vanadium powders. Then, 17-4PH stainless steel is successfully deposited on the vanadium interlayer made from the angular powder. However, on the surface of the vanadium interlayer made from the spheroidized powder, delamination of 17-4PH occurs during deposition. The main cause of this phenomenon is presumed to be the high thickness of the vanadium interlayer and the relatively high level of surface oxidation of the interlayer.

Corrosion properties of dissimilar friction stir welded 6061 aluminum and HT590 steel were investigated to understand effects of galvanic corrosion. As cathode when coupled, HT590 was cathodically protected. However, the passivation of AA6061 made the aluminum alloy cathode temporarily, which leaded to corrosion of HT590. From the EIS analysis showing Warburg diffusion plot in Nyquist plots, it can be inferred that the stable passivation layer was formed on AA6061. However, the weld as well as HT590 did not show Warburg diffusion plot in Nyquist plots, suggesting that there was no barrier for corrosion or even if it exists, the barrier had no function for preventing and/or retarding charge transport through the passivation layer. The open circuit potential measurements showed that the potential of the weld was similar to that of HT590, which lied in the pitting region for AA6061, making the aluminum alloy part of the weld keep corrosion state. That resulted in the cracked oxide film on AA6061 of the weld, which could not play a role of corrosion barrier.

전 세계적으로 극심한 가뭄현상이 반복적으로 발생하고 있으며, 이러한 가뭄을 분석하기 위한 연구가 다수 진행되고 있다. 최근 코플라 함수를 활용한 이변량 가뭄빈도해석에 대한 연구가 다수 진행된 바 있으나, 대부분 지점빈도해석에 국한되어 진행되었으며, 통계적으로 부족한 자료의 기간을 보완하기 위한 대안으로 지역빈도해석 개념을 도입한 연구는 미진한 실정이다. 이러한 점에서 본 연구에서는 기존의 베이지안 기법과 코플라 함수를 연계한 이변량 지역빈도해석 모형을 개발하였다. 최종적으로 이변량 코플라 가뭄 지역빈도해석 모형을 한강유역에 적용하여 2013-2015년에 발생한 가뭄 사상을 평가하였으며, 기존에 개발된 이변량 지점빈도해석 결과와 비교를 통해 모형의 해석결과에 대한 신뢰성을 확보하였다. 결과적으로 이변량 지점빈도해석에 비해 가뭄사상에 대한 결합재현기간의 불확실성 구간이 약 3배 가까이 감소하였으며, DIC 통계량 산정결과 약 15 이상 개선된 것을 확인하였다. 본 연구를 통해 제안된 베이지안 코플라 기반 이변량 가뭄 지역빈도해석 모형은 가뭄자료의 분포특성 및 자료간의 상관성을 효과적으로 재현하는데 유리할 뿐만 아니라, 지역적인 가뭄특성을 효과적으로 평가할 수 있는 장점을 확인할 수 있었다.

세계의 모든 국가들은 국가내 지역간 경제적 격차 문제를 가지고 있으며, 특히 유럽연합(EU)의 경우 경제적 발전단계가 각기 다른 27개 회원국들로 구성되어 있어 이러한 지역간 격차문제는 더욱 심각하다고 할 수 있다. 하지만 유럽연합 초기에는 지역정책을 주로 회원국의 손에 맡겨두고 공동체 차원에서는 적극적인 지역정책을 펼치지는 않았다. 그 후 1970년대에 새로운 회원국을 받아들이는 과정에서 유럽지역개발기금(ERDF)을 신설하게 되었고, 이를 계기로 유럽연합의 지역정책은 공동체내에서 주요한 정책으로 부상하였다. 특히 유럽연합이 1980년대 회원국들 간의 단일시장을 추구하고, 1990년대에 경제통화동맹(EMU)을 추진하는 과정에서 지역정책의 역할이 더욱 강화되었고 관련된 기금의 규모가 4배 가까이 증가하게 되었다. 최근에는 중 동유럽국가로 회원국이 확장되면서 회원국들 간의 사회 경제적 격차가 더욱 확대되어 이의 해소를 위한 연합차원에서의 지역정책 역할이 그 어느 때 보다도 절실히 요구되고 있는 시점이다. 이러한 관점에서 이 논문에서는 EU가 설립초기부터 지역간 불평등 문제들을 해소하기 위해 시행해 왔던 지역정책들의 내용과 배경, 발전과정 등을 검토해 본다.

We simulated and compared present and future ocean circulation in the East China Sea using an East Asia Regional Ocean model. Mean climate states for 1990~1999 and 2030~2039 were used as surface conditions for simulations of present and future ocean circulation, which were derived from the simulations of three different global climate models, ECHAM5-MPI, GFDL-CM2.0 and MIROC3.2_hires, for the 20th century and those of 21st century as projected by the IPCC SRES A1B. East Asia Regional Ocean model simulated the detailed patterns of temperature, salinity and current fields under present and future climate conditions and their changes instead of the simple structures of global climate models. To some extent, there are consistent ocean circulation changes derived from the three pairs corresponding to the global climate model in so much as the temperature increases not only in winter but summer at both the surface and bottom and that temperature and salinity changes are prominent near the Chinese coast and in the Changjiang bank. However, the simulated circulations are different among each other depending on the prescribed atmospheric conditions not only under present climate but also with regard to future climate conditions. There is not a coincident tendency in ocean circulation changes between present and future simulations derived from the three pairs. This suggests that more simulations with different pairs are needed.

This study assesses the performance of the Weather Research and Forecasting (WRF) model in reproducing regional climate over CORDEX-East Asia Phase 2 domain with different cumulus parameterization schemes [Kain-Fritch (KF), Betts-Miller-Janjic (BM), and Grell-Devenyi-Ensemble (GD)]. The model is integrated for 27 months from January 1979 to March 1981 and the initial and boundary conditions are derived from European Centre for Medium-Range Weather Forecast Interim Reanalysis (ERA-Interim). The WRF model reasonably reproduces the temperature and precipitation characteristics over East Asia, but the regional scale responses are very sensitive to cumulus parameterization schemes. In terms of mean bias, WRF model with BM scheme shows the best performance in terms of summer/winter mean precipitation as well as summer mean temperature throughout the North East Asia. In contrast, the seasonal mean precipitation is generally overestimated (underestimated) by KF (GD) scheme. In addition, the seasonal variation of the temperature and precipitation is well simulated by WRF model, but with an overestimation in summer precipitation derived from KF experiment and with an underestimation in wet season precipitation from BM and GD schemes. Also, the frequency distribution of daily precipitation derived from KF and BM experiments (GD experiment) is well reproduced, except for the overestimation (underestimation) in the intensity range above (less) then $2.5mm\;d^{-1}$. In the case of the amount of daily precipitation, all experiments tend to underestimate (overestimate) the amount of daily precipitation in the low-intensity range < $4mm\;d^{-1}$ (high-intensity range > $12mm\;d^{-1}$). This type of error is largest in the KF experiment.
