  • The traditional methodology of Korean regional studies had been shifted by geographic thoughts and philosophy as follows; Environmentalism or Environmental determinism stemming from geomancy were dominant methodology in the Korea era. An idiographic approach was introduced based on the encyclopedic description of geographic factors of villages for the centeralization of power in the Chosun era. A systematic geography that pursues scientific laws of regional differences which results from the interactions of human and nature had emerged through field works of some practical school in the later Chosun era.

  • The objective of this research is to find out the relationship among resilience of young children, their interactive peer play, and mothers' overprotective parenting attitudes. The research was conducted for 455 children aged 3~5 and their mothers of day care centers in the cities of Kimje and Iksan. To measure resilience of young children, the rating scale for parents and teachers(Koo, 2010) adapting DECA(1999) was used. And the interactive peer play scale of Choi and Shin(2008) adapting PIPPS(1998) and the Parental Protectiveness of Do and Falbo(1999) was used. The results from this research are as follows. First, there is a generally significant positive correlation between resilience and interactive peer play of young children. Resilience of young children gets higher as interactive peer play of young children gets higher. Second, there is low negative correlation between resilience and mothers' overprotective parenting attitudes. Resilience of young children gets higher as mothers' overprotective parenting attitudes get low.

  • The present study was conducted to investigate physical characteristics, food habits of pregnant women with gestational diabetes mellites(GDM). The subjects were consecutive pregnant women, 21 GDM and 43 non-GDM controls who received antenatal care at the Obstetrics and Gynecology clinic. There were no significant difference in the mean age between the two groups(GDM:30.8years, non-GDM:30.5years). Significant differences were observed in several anthropometric characteristics such as height(GDM:159.7cm, non-GDM:162.3cm), prepregnancy weight(GDM:61.6kg, non-GDM:54.1kg), body mass index(GDM:23.9kg/$m^2$, non-GDM:20.5kg/$m^2$), and triceps skin fold thicknesses(GDM:30.9mm, non-GDM:24.7mm) between the two groups. The GDM group had an high incidence of(52.4%) family history of diabetes mellitus than those of control group(23.3%). In the GDM group, more irregularities of meals and more bed-time snacking were observed than those of control group. The intake amount of carbohydrates as well as the total energy were significantly higher in the GDM group when thery were compared with the control. These results suggest that the GDM women in Korea do exhibit clearly distinctive anthropometric and dietary characteristics. Nutritional management such as weight control before conception and throughout pregnancy, monitoring total energy and carbohydrate intakes, and implementing more rigorous meal scheduling might be beneficial for the prevention or reduction of the prevalence of the GDM or its complications.

  • The technology for characteristics analysis of device for high integration is changing rapidly. Therefore to understand characteristics of high integrated device by computer simulation and to fabricate the device having such characteristics became one of very important subjects. As devices become smaller to submicron, we have investigated MOSFET built on an epitaxial layer(EPI) of a heavily-doped ground plane by TCAD(Technology Computer Aided Design) to develop optimum device structure. We compared and analyzed the characteristics of such device structure, i.e., impact ionization, electric field and I-V characteristics curve with lightly-doped drain(LDD) MOSFET. Also, we presented that TCAD simulator is suitable for device simulation.

  • Co-combustion of sludge with coal is proposed as an alternative option for sludge disposal instead of ocean dumping. Because the combustion of sludge can cause emissions of various air pollutants, it is important to understand the characteristics of sludge combustion flue gases. Especially, very few studies are found to investigate mercury emissions from the co-combustion of sludge with coal. In this study, coal and sludge samples were prepared with different mixing ratios. These samples were combusted in a bench-scale combustor, and their flue gases were analyzed. Due to higher mercury content in the sludge sample, higher mercury emissions were found with an increase in a ratio of sludge to coal. Compared to the combustion flue gas of the coal sample, higher levels of mercury oxidation were found in the combustion flue gas of the samples including sludge.

  • 본 논문에서는 이러한 문제점을 개선하기 위해 상완 동맥 영역에 대한 RGB 채널을 HSV 채널로 변환한다. 변환된 HSV 채널에 대해 고혈압 영역의 특징을 강조하게 하기 위해 밝기 값을 나타내는 V값을 조절한다. 조절된 HSV 채널을 다시 RGB 채널로 변환한 후, Fuzzy C_Means 기반 무게중심과 Possibilistc C_Means 기반 무게 중심을 기반으로 새로운 무게 중심을 구하여 픽셀들을 클러스터링하여 상완동맥 영역의 고혈압 영역을 추출한다. 추출된 상완 동맥의 고혈압 영역에 대해 헤모글로빈 색소 정보를 나타내는 IHb 값을 이용하여 상완 동맥의 고혈압 영역에서 유사한 헤모글로빈 색소 정보를 가지는 영역을 분할한다. 분할된 영역들을 혈류의 속도를 나타내는 색상표와 대조하여 고혈압의 진행에 대해 분석하는 방법을 제안한다. 제안된 방법을 색조 도플러 초음파 영상을 대상으로 실험한 결과, 제안된 방법이 고혈압의 진행에 대한 분석 결과와 색조 도플러 초음파 영상 장비에 나타난 고혈압 진행 결과와 거의 일치하는 것을 확인할 수 있었다.

  • This study is for Gamigyejitang's effects on the histological change s of allergic rhinitis. for this purpose, the changes of the mucosa epithelium and the submucosa tissue of nose were observed and the effects on neutrophil count and eosinophil count in blood were estimated. The rats were divided into normal group, control group and experimental group. Control group was administered normal saline and experimental group was administerd Gamigyejitang. The results obtained were as follows: 1. The epithelium layer of experimental group was restored to normal thickness and state nearly. 2. The submucosa tissue of experimental group was restored to normal state nearly. 3. The neutrophil count and eosinophil count were decreased in the experimental group(Gamigyejitang treated group) as compared with the control group but not significantly. According to above results, it is supposed that Gamigyejitang has considerable effect on allergic rhinitis and could be applicated to treat the nasal mucosa edema and several symptoms.

  • Semi-solid Al-Zn-Mg alloys were produced by using a cooling plate method in order to investigate the extrudability. Al melt was poured on cooling plate which was adjusted at $60^{\circ}$ with respect to the horizontal plane, and the melt was cooled by water circulation underneath. Obtained Semi-solid feedstock has globular microstructure but also contains considerable amount of gas pore. Due to the pore, tensile elongation of the semi-solid feedstock was very low and it doesn't show yield point phenomenon. Isothermal hot extrusion was carried out using at $400^{\circ}C$ with a ram speed of 1mm/sec and an extrusion ratio of 25:1. The extruded bar show noticeably improved tensile ductility and strength because pore volume fraction decreased from 5% to 0.8% after extrusion. Mechanical properties of the semi-solid extruded bar were compared with that of commercial casting alloy.

  • Lots of roadway tunnel have been almost constructed in forms of closely-spaced tunnel in korea. If closely-spaced tunnel is not constructed at a sufficient distance between tunnels, the problem of stability can occur. However, the case that can not secure a sufficient distance between tunnels can occur due to a difficulty in buying a lot and an issue of popular complaint and environmental disruption. Generally, tunnels are not influenced by each other when a center distance between tunnels is two times longer than tunnel diameter under the complete elastic ground and five times under the soft ground. In this study, the scaled model tests of closely-spaced tunnel by using homogeneous material were performed and induced displacements were measured around the tunnel openings during excavation. The influence of distance between tunnels on the behavior of closely-spaced tunnel was investigated.

  • In 2012, Korea adopted RPS after having implemented FIT for 10 years since 2002. We show how the choice of policy between RPS and FIT affects firm's choice of intermediate goods between a domestic and a foreign supplier, given the presence of transaction costs, When transaction costs are not sufficiently high, RPS is found to create a favorable environment for the domestic provider, which has comparative disadvantage initially, to be able to enter the market and to catch up with the foreign provider. The result implies that the Korean government's decision to implement RPS was optimal, given Korea's comparative disadvantage in green energy relative to major developed countries.
