This study is aimed at understanding the wisdom of our ancestors in Korean traditional villages and finding out cues to designate and utilize community space in planning residential area in villages by examining community space in Korean traditional villages from cultural landscape point of view. This study designated 18 Korean traditional villages which have been preserving Korean traditional culture up to now, so deserve conservation from historical, cultural and artistic viewpoint. This study divided community spaces in each village into social area and ritual area depending on their uses and functions based on the results of pilot study and main study. In addition, ritual areas were also divided into Confucian ritual area and ethnic ritual area. Specifically, this study examined characteristics of space location and users by understanding the location of community space factors in the 18 villages. As for the factor analysis of community spaces, community factors established after the modern age were examined from modern viewpoint, and factors which had been destroyed or lost their original functions were examined from retrospective viewpoint. In conclusion, this study found out that cultural landscape in Korean traditional villages were affected by social relationship among villagers. The community spaces of villagers were multiple-function space rather than a space which was exclusively used by a specific class. Though the occupation of these spaces was separated and differentiated depending on sexes and ages, villagers tried to understand and respect each other through tacit communication.

University dormitories play an important role in both the campus experience and academic achievement, as well as providing the students with their basic necessities. Further, there is a high demand to increase the capacity in order to raise the retention rate and to invite more foreign students. Students' social interaction and sense of community (SOC) also play an important role in reducing the stress associated with studying and home sickness and, consequently,the campus is a place that provides positive opportunities for their personal growth and adaptation into their peer group social culture. The purpose of this study is to investigate the effects of the physical environment of the dormitory facilities on the students' sense of community and social interaction in across-cultural background.The ${\chi}^2$ analysis indicated that individual characteristics exist regarding SOC, however, there were no statistically significant differences between the two cultural groups. The factors of SOC and physical environment were higher in the Korean student group than in the U.S. group. The regression analysis indicated that the U.S. students considered a physically comfortable environment as the primary issue for social interaction, while the Korean group placed more emphasis on a family-oriented home environment. The linear analysis confirmed that satisfaction with the physical environment influenced the social interaction and SOC level. Finally, this study suggests that creating a homely environment is more important than the functioning of the institution in university dormitory planning.

In this study, we performed a systematic review and meta-analysis to identify the effects of exercise on endothelial progenitor cells (EPCs) in patients with cardiovascular disease (CVD). We conducted database searches (Cochrane Library, PubMed, EMBASE, ScienceDirect, CINAHL, Scopus, KoreaMed, KISS, RISS, KMBASE) for the effect of exercise on cardiovascular disease, using heart disease, coronary artery disease, heart failure, cardiovascular disease, exercise, motor activity, rehabilitation, and endothelial progenitor cells as the keywords. Of the 539 studies identified, 9 met the inclusion and exclusion criteria. Comprehensive Meta-Analysis version 2.0 was used to analyze the effect size and the publication bias was checked with a funnel plot. Exercise was found to improve the VEGF (vascular endothelial growth factor), CD34+KDR+, and endothelial function, assessed via FMD (flow-mediated dilation), in the exercise vs. control groups, viz. 2.008 (95% CI 0.204-3.812), 1.399 (95% CI 0.310-2.489), and 1.881 (95% CI 0.848-2.914), respectively. Exercise improved the VEGF, number of EPCs, and endothelial function in the CVD patients. Considering the increasing prevalence and mortality rates for cardiovascular disease in Korea, the findings of this study that analyzed the effects of exercise on EPCs might provide guidelines for planning exercise interventions for patients with CVD.

The purpose of this study was to investigate the possibility of medicinal plants application as an edible functional food resource. This research was planned to apply Artesmisia capillaris, which is one of the most widely used oriental medicinal resource into beverages, and to evaluate the validity and the nutrients of the developed beverage with Artemisia capillaris. Following this plan, we analyzed contents of the general nutritional composition, mineral and amino acid contents. And to evaluate the improvement of blood circulation and the ability to recover from fatigue, we had a group of athletes to regularly take the beverage before and after exercise and checked the heart rates, and blood components before exercise and after exercise. Brix, pH and titratable acidity of develoued drink were 9.2%, 4.4 and 0.04%, respectively. The approximate nutritional composition of beverage was carbohydrate, 2.70%, crude protein, 6.00%, crude ash, 0.20%, and crude fat, 0.10%. And developed beverage contained essential amono acids and minerals (p, Ca, K, Na, Fe, Mn, Zn). Heart rates, lactic acid, glucose, creatinine, LDH, GOT, GPT and lipid concentratios in blood were decreased after taking the beverage with Artemisia capillaris for 6 weeks, both in stable condition and after exercise. Since the athletes who participated In our research were doing aerobic exercise regularly, we judged that this result was formed not only by aerobic exercise, but also by the function of developed beverage with Artemisia capillaris the athletes took for 6 weeks. We believe that taking the beverage regularly will help the improvement of the public health and the athleticism of the athletes. We hope that this result will be used as the basic resource in developing of the beverage with Artemisia capillaris in the near future.

장기유출해석 모델은 수자원의 안정적인 확보와 이용, 유역단위 기초자료 조사관리 등을 위하여 수자원 장기종합계획 및 전국유역조사사업 등에 활용되고 있다. 주로 국외에서 개발된 모형이 활용되고 있어, 국내의 여건에 맞추어 편의성이 개선된 모형을 찾는 것은 매우 어려운 일이다. 또한, 유출해석을 수행하기에 앞서 지속적으로 업데이트된 모델에 대한 객관적인 평가를 수행한 사례는 드물다. 따라서, 본 연구에서는 국내에서 주로 활용되고 있는 장기유출해석모델(TANK, SWAT, SSARR, PRMS 등)에 대한 비교검토를 토대로 각종 사업과의 연계성, 계산의 효율성, 정확도 등을 고려하여 USGS에서 개발한 PRMS v.4.0.2를 기반으로 국내유역에 활용이 가능하도록 개선한 $K-BASIN^{RR}$ 및 입력자료 전처리기를 개발하였다. PRMS 모형은 융설 및 지하수 흐름 등 다양한 기능을 포함하여 강우유출 분석에 활용성 높은 모형으로 평가받고 있으나, 국내 OS환경 및 활용 단위계에서 활용성이 떨어지는 단점이 있다. 본 연구에서는 소스코드 개선 및 GUI구축을 통하여 PC 환경에서 구동이 쉽도록 재구성하였고, 사용자 편의성 확보를 위한 입력자료 전처리기를 개발함으로써 수자원단위지도 3.0, 임상도 재분류 테이블, 토양도 재분류 테이블의 DB화 및 모형의 구동을 위한 HRU분할, 입력자료 생성이 가능하도록 하였다. 매개변수 최적화를 위하여 하천 유량뿐만 아니라 기저유출량을 대상으로 Monte-Carlo 시뮬레이션 기반의 매개변수를 최적화 기능을 탑재하였다. 개발된 모형의 적용성 평가를 위하여 용담댐 시험유역을 대상으로 11년 간(2005-2015)의 강우 및 온도자료를 입력자료로 활용하여 모의한 결과 샘플의 개수에 따라 NSE(Nash-Sutcliffe Efficiency)를 0.9까지 추정이 가능함을 파악하였다. 또한, 유출량과 기저유출에 대하여 동시에 최적화를 수행하는 경우 NSE를 유출량에 대하여 0.8, 기저유출량에 대하여 0.6까지 추정이 가능하였다. 최적화된 모의 결과에 대한 검토를 위하여 계산증발산량을 측정증발산량과 비교한 결과, 유사한 패턴을 나타내는 것을 확인할 수 있었다. 본 연구에서 개발한 $K-BASIN^{RR}$을 활용하는 경우 장기유출해석 업무에 효율성 및 정확도를 향상할 수 있을 것으로 판단된다.

Full-mouth rehabilitation with increasing vertical dimension can be used for patients with severely worn teeth. In severely worn teeth also, the alveolar process can be elongated to compensate for the reduced vertical dimension, and the patient's vertical dimension of occlusion can be kept constant. However, full-mouth rehabilitation with increasing vertical dimension must be carefully chosen, because the vertical dimension can be reduced by tooth wear. It is important to establish a treatment plan with the systematic diagnosis of the change in the vertical dimension and gain space for the prosthesis. It is necessary to change the vertical dimension to secure the restoration space and select the minimum vertical dimension elevation for the esthetic and functional goal. In this case report, the patient complained of difficulty during chewing due to a worn dentition and wanted esthetic improvement of the short mandibular anterior teeth. After systematic evaluation and diagnosis, we performed full-mouth rehabilitation with minimum vertical dimension elevation to obtain the space for restoration. This resulted in a stable and harmonious occlusion, and the functional and esthetic problems of the patient were solved after treatment. The patient was satisfied with the results of the treatment and maintained stable occlusion during the follow-up period.

In order to prevent local extinction of organisms and to preserve biodiversity, it is important to ensure connectivity between habitats. Even if the habitat is exposed to various disturbance factors, it is possible to avoid or respond to disturbances if they are linked to other habitats. Habitat connectivity can be assessed from a variety of perspectives, but the importance of functional connectivity based on species movement has been emphasized in recent years due to the development of computational capabilities and related software. Among them, Circuitscape, which is a connectivity evaluation tool, has an advantage it can provide detailed reference data for the city planning because it maps ecological flows on individual grid based on circuit theory. Therefore, in this study, the functional connectivity of Suwon was evaluated by applying Circuitscape and then, the ecological corridor to be conserved and supplemented was suggested based on it. The results of this study are expected to effectively complement the methodology related ecological corridor/axis, which was previously provided only in the form of a diagram, and to be effective in management of development project and urban planning.

The purpose of this study is to provide policy recommendations for manpower planning by forecasting the supply and demand of Medical Technologists. Supply was estimated using an in-and-out movement method with a demographic method based on a baseline projection model. Demand was projected according to a demand-based method using the number of clinico-pathologic examinations taken for Medical Technologists. Over- or undersupply of Medical Technologists will depend on the productivity scenario and assumptions and ultimately on governmental policy direction. In other words, whether the production of Medical Technologists is higher or lower than the current level depends on the government policy to consider insurance finances. In this study, we assessed 'productivity scenario 3' based on the productivity as of 2012, when the government's policy direction was not considered. Based on the demand scenario using the ARIMA model, the supply of Medical Technologists is expected to be excessive. This oversupply accounts for less than 10% of the total and therefore should not be a big problem. However, given that the employment rate of Medical Technologists is 60%, it is necessary to consider policies to utilize the unemployed. These measures should expand the employment opportunities for the unemployed. To this end, it is necessary to strengthen the functions of laboratories in the public health center, to increase the quota of Medical Technologists, to assure their status, to establish a permanent inspection system for outpatient patients, and to expand the export of Medical Technologists overseas.
