This study was conducted to investigate the difference of perception about nutritional problems and food intakes and nutrition knowledge score and realities of nutrition education between parents and preschool teachers. This research can be summarized as follows: there was the statistical difference of perception (${\chi}^2$= 52.451, p = 0.000) about nutritional problem of preschoolers between parents and preschool teachers. Parents (56.4%) and teachers (58.5%) identified eating only what they want as the most common nutritional problem of children, but they had different perception about the other problems. To parents, "No nutritional problem" (16.3%) is the second and "Overindulgence of processed food" (11.1%) is the third problem of preschoolers. To teachers, "Overindulgence of processed food" (23.8%) is the second and "Obesity" (14.3%) is the third problem. The perception on food intakes of preschoolers was statistically different in meats (${\chi}^2$= 8.892, p = 0.030), fish (${\chi}^2$= 32.241, p = 0.000), beans (${\chi}^2$= 14.770, p = 0.005), vegetables (${\chi}^2$= 12.706, p = 0.013), fruits (${\chi}^2$= 14.438, p = 0.006) and milk & dairy products (${\chi}^2$= 28.591, p = 0.000) between parents and preschool teachers. However, nutritional knowledge was not different between parents and preschool teachers. While 96.6% of preschool teachers felt that it was necessary to educate preschoolers, only 41.5% of them said that they fulfilled nutrition education, showing that nutrition education was not adequately carried out on the spot. Therefore providing basic materials through which nutritional management guidance and proper nutrition education for preschoolers can be carried out by investigating and analyzing knowledge on their nutrition and meal guidance activities for preschooler teachers and parents.

Objectives : The purpose of this study is to figure out and establish the basic data that can help improve management of oral healthcare for the international marriage immigrant women. Methods : In this sense, we surveyed questions on 237 women out of 1,300 immigrant women, who have participated in the program by multi-cultural household supporting center, in a fashion of face-to-face investigation and on-the-spot direct cavity inspection simultaneously from May 1 to October 31, 2010. Collected data were electro-statistically computerized under SPSS 17.0 program and analyzed with frequency analysis, recurrence analysis and logistic regression analysis respectively. Results : The number of filled teeth got lower when they had lower number of dental visits. Women from the Philippines had the highest number of defect teeth, and the number of fixed prosthetic appliance became less when they had less number of dental visits. When they had no experience of oral health education, they had less fixed prosthetic appliances. There was higher percentage of periodontal disease when they did not have dental visit compared with the dental visit cases. Conclusions : Preparation of a policy for east Asian immigrant women for them to visit dentist comfortably and expansion of systematic oral health education are highly recommended.

In order to overcome the image quality limitations of the conventional C-arm, a flat panel detector (FPD) is used to enhance spatial resolution, detective quantum efficiency, frame rate, and dynamic range. Three-dimensional (3D) visualized information can be obtained from C-arm computed tomography (CT) equipped with an FPD, which can reduce patient discomfort and provide various medical information to health care providers by conducting procedures in the interventional procedure room without moving the patient to the CT scan room. Unlike a conventional C-arm device, a C-arm CT requires different basic safety and essential performance evaluation criteria; therefore, in this study, basic safety and essential performance evaluation criteria to protect patients, medical staff, and radiologists were derived based on International Electrotechnical Commission (IEC) standards, the Ministry of Food and Drug Safety (MFDS) standards in Korea, and the rules on the installation and operation of special medical equipment in Korea. As a result of the study, six basic safety evaluation criteria related to electrical and mechanical radiation safety (leakage current, collision protection, emergency stopping device, overheating, recovery management, and ingress of water or particulate matter into medical electrical (ME) equipment and ME systems: footswitches) and 14 essential performance evaluation criteria (accuracy of tube voltage, accuracy of tube current, accuracy of loading time, accuracy of current time product, reproducibility of radiation output, linearity and consistency in radiography, half layer value in X-ray equipment, focal size and collimator, relationship between X-ray field and image reception area, consistency of light irradiation versus X-ray irradiation, performance of the mechanical device, focal spot to skin distance accuracy, image quality evaluation, and technical characteristic of cone-beam computed tomography) were selected for a total of 20 criteria.

Urbanization from agricultural/forest areas has been causing increased runoff and pollutant loads from it. Thus, numerous models have been developed to estimate NPS loading from urban area and Long-Term Hydrologic Impact Analysis (L-THIA) model has been used to evaluate effects of landuse changes on runoff and pollutant loads. However, the L-THIA model could not consider rainfall intensity in runoff evaluation. Therefore, the L-THIA model, capable of simulating runoff using 10-minute rainfall data, was applied to the study areas for evaluation of estimated runoff and NPS. The estimated Nash-Sutcliffe coefficient (NSE) values were over 0.6 for runoff, BOD, TN, and TP for most sites and watershed. The calibrated model was further extended to other counties for pollutant load potential evaluation. Pollutant load potential maps were developed and target areas were identified. As shown in this study, the L-THIA 2012 can be used for evaluation runoff and pollutant loads with limited data sets and its estimation could be used in identifying pollutant load hot spot areas for implementation of site-specific Best Management Practices.

This landscape design proposal was presented to a design competition for the KangWon Province Police Agency(KPA). The site, about 27,711 $m^2$, is located at 293-4 Udu-dong, Chunchun, KangWon-Do. Design objectives of the KPA were to build a symbolic place which fall community members with pride, to elevate an identity and status of the KPA by creating a landscape correspondent to the concept of the building design, to provide community residents with a space to enjoy cultural and social activities, and to make environment friendly space. The main concept was developed by one of characteristics of the traditional spatial structure of Korea known as an, 'Open and Closed spatial structure.'By re-interpreting the traditional spatial structure and applying it to the site, the design met the various desires of the KPA. The site is primarily segmented into 6 sub spaces; entrance space Podori plaza, symbolic court, police billeting area, sports area, and rear rest area. The entrance space, Podori plaza, and symbolic court on the south-west part of the site represent the publicity of the site as the concept of ″open space.″ On the contrary, considering the specialty of police affairs, the north-east part of the site, which contains the police billeting area and rest area, were designed to maintain security by using the concept of ″closed space.″ To express an identity of the KPA, 'Podori', a police mascot, the plaza was designed and is suppose to function as the hub of the community. In the front section of the plaza, a symmetrical planting pattern, centering the strong axis, was introduced to strengthen its symbolic meaning. Traditional window frames such as the pattern of 'Pisal-jige'and 'Umulsal-jige' were used for the paving system which is applied as the environment friendly design. Site facilities and furnitrue were placed at every important spot in order to connect various spaces organically. As these well-tied spaces properly shared their function, spatial sequence and management would be promoted. The entire space was designed to allow free access of handicapped people. This proposal is meant to create a new image of KangWon province and to enhance the way of inhabitants' think about their community.

Most scholars calssify caves into natural resource, but caves possess values of natural and human resource, mix up the features of natural resources and human resources. Now, caves are distributed 260 in Korea. Seongryu Cave is showed in 1967 for the first time, till 1997 12 caves is opened to tourist. But since 1996 the 12 show caves of all is not launched the safety and environment-protection check-up adduced reason for IMF. Then caves must maintain environment of the normal temperature, humidity and dark. But the environment of caves are destroyed by tourism development. Thus to maintain environment of caves, it used to consider the counterplan as follows in restraint of the environmental change. Firstly, in case of development work to open caves, it must keep up with the prototype. Secondly, it must establish a freight depositary to prevent the influence of the caves's stain and damage due to tourist's objects. Thirdly, to maintain the normal temperature and humidity, it must install artificial poultice equipment of the inner parts of caves. Fourthly, in order to prevent the occurrence of $CO_2$, it must assessment of the optimum number of the greatest stayer. Fifthly, the control of closure for a given period of time is useful of the restoration to the cave's original state. Sixthly, by means of make narrow entrance, it should not influence the outer's air on the inner parts on caves. Seventhly, to keep the temperature of the inner part of caves, the lightening should be maintained moderately considering the convenience of a tour. Eightly, when water-proof cables for the lightening bulbs are connected each other, silicon tape is suitable and circuit breakers should be installed at the diverging points of the cables. Ninthly, the direction and angle of the lightening must be changed periodically to prevent green-pollution at the lightening spot. Lastly, when facilities and arrangements are equipped, corrosive materials should be excluded if circumstances allow.

산불피해강도지수(CBI, Composite Burn Index)는 미국 산림청(USDA Forest Service)에서 위성영상을 이용하여 산불 피해강도 측정을 위해 개발한 산불피해 현장 조사 지수이다. 국내의 경우 별도의 산불피해 지수가 없어, 미국 CBI를 산불 피해지 조사에 준용하여 왔으나, CBI는 국내 여건에 맞지 않다는 지적이 제기되어 산불피해강도지수(KCBI, Korean Composite Burn Index)를 개발하게 되었다. 따라서 본 연구는 미국 CBI에 기초하여 한국형 산불피해강도지수(KCBI, Korean Composite Burn Index)의 개발과 검증에 목표를 두고 수행되었다. KCBI는 CBI에 기초하여 국내 현장적용 후 문제점을 파악 후 정교화 하였으며, 위성영상 결과와의 적합성 검토를 위하여 2011년도 산불 피해지중 상대적으로 피해 규모가 큰 울진과 영덕 산불피해지를 연구 대상지로 선정 후 각 44개 지점에서 산불피해 강도를 평가하였다. 산불피해강도(BS, Burn Severity)는 산불발생 후 1개월 후에 촬영된 SPOT 영상을 이용하여 NDVI(Normalized Difference Vegetation Index) 값으로 계산하였으며, 상관분석과 오류메트릭스(Confusion Matrix)를 이용하여 유효성을 검증하였다. 분석 결과 울진피해지는 (r = -0.544, P<0.01), 영덕피해지 (r = -0.616, P<0.01)로 나타났다. 부의 상관관계를 나타난 이유는 NDVI의 DN 값은 낮을 수 록 높은 피해강도를로 나타내며, 높을수록 낮은 피해강도를 나타내기 때문이다. 본 결과로 제시된 KCBI는 국내 산불 피해 현장에서 적용 가능한 것으로 판단되었다. 하지만 등급분류 방법과 기대치 보다 낮은 상관도 등의 문제점도 나타났다. 또한 오류메트릭스 분석결과 KCBI가 일부 높은 산불 강도 등급에 치우쳐 분포하는 현상 등이 나타났다. 제기된 문제점들을 바탕으로 향후 KCBI를 더 많은 한국 산불피해지에 적용함으로써, 추후 연구를 진행해야 할 것이다.
