주차장에서 일어날 수 있는 비매너 주차로 인한 충돌을 사전에 예방하기 위한 단속시스템이다. 주차장에서 일어날 수 있는 장애인, 전기차 전용 주차구역에 일반차량 주차, 2개 차선을 물고 주차하는 차량이 있다. 위와 같은 차량을 딥러닝 객체인식 기능을 통해 비매너 주차를 감지하여 알려준다. 비매너 주차 상황이 찍힌 사진이나 영상을 학습데이터로 사용하여 상황을 인식할 수 있도록 학습데이터를 제작하고 그 상황을 인식하여 비매너 주차 유무를 판단한다. 주차장의 환경을 좀 더 쾌적하게 함으로써 주차장 이용자간 충돌을 줄이는데 목적이 있다. It is a enforcement system to prevent collisions caused by unmanageable parking that may occur in parking lots. There are handicapped people who can get up in parking lots, general vehicles parked in electric vehicle parking areas, and vehicles parked in two lanes. The vehicle above is detected and notified through the deep learning object recognition function. By using a picture or video of an unmanageable parking situation as learning data, the learning data is produced so that the situation can be recognized, and the situation is recognized to determine the presence or absence of unmanageable parking. The purpose is to reduce collisions between parking lot users by making the environment of the parking lot more comfortable.

The purpose of this study is to quantitatively evaluate the amount of carbon storage for trees in forest ecosystem to support the foundation for carbon neutrality implementation in Korea National Park. It targeted 22 national parks designated and managed as national parks in Korea, and conducted research on forest trees in the terrestrial ecosystem among various natural and ecological carbon sink. The survey and analysis method followed the IPCC guidelines and the National Greenhouse Gas Inventory in Korea. The amount of tree carbon storage in the forest ecosystem of Korea National Park was confirmed to be about 218,505 thousand CO₂-ton and the amount of carbon storage per unit area was 570.8 CO₂-ton per hectare. Compared to 299.7 CO₂-ton per hectare, the average carbon storage per unit area of the entire Korean forest, it was found that about twice as much carbon was stored when assuming the same area. In other words, it means that the tree carbon storage function of the national park is about twice as high as that of the average tree carbon storage function of entire Korean forest. It has great implications in Korea National Park not only provides biodiversity promotion and exploration services as a national protected area, but also performs excellent functions as a carbon sink.

2007년부터 시행되고 있는 한국의 주택연금제도는 정부가 보증하는 역모기지 프로그램이다. 한국주택금융공사가 매년 실시하고 있는 연간 설문 자료를 이용하여 미래에 주택연금을 이용할 의향이 있는 가구들에 대해 주택연금에 대한 수요를 추정하였다. 본 논문에서는 이충기․박상수(2014)의 연구를 확장하여 미래 기대와 코호트 효과를 고려하여 순서형 로짓 모형을 설정하였다. 설문에서 진술된 가구의 의향이 미래에 대한 기대에 근거하고 있다는 점을 적절하게 평가하기 위해 몇 가지의 가정을 바탕으로 미래의 기대형성 과정을 계량경제학적으로 모형화하여 주택연금 수요를 예측하고자 하였다. 주택연금에 대한 수요 추정 결과에 따르면, 주택연금 프로그램에 대해 후세대들이 보다 덜 긍정적인 경향이 나타난 반면 저소득 계층은 보다 긍정적으로 나타났다. The J ooTaekYeonKeum is the government guaranteed reverse mortgage program that Korean Government has been implementing since 2007. We extended Lee and Park’s(2014) demand estimation for the reverse mortgage loans in Korea using the yearly survey data, conducted by Korea Housing Financing Corporation, for household’s intention to use J ooTaekYeonKeum in the future. In order to appropriately appreciate the fact that the stated intentions in the survey were based on households’ expectations for their future, we adopted an econometric procedure that incorporated expectations explicitly as well as cohort effects. Our findings include: demands for reverse mortgage loans are estimated similar to that of Lee and Park(2014); later generations tend to be less positive for having the reverse mortgage program; lower income groups are more positive for the program.

Duodeno-colonic fistula is an enterocolonic fistula that occurs as a complication of Crohn`s disease. Symptoms of duodeno colonic fistula are similar to those of Crohn`s disease, such as weight loss and diarrhea. The treatment of choice is surgery, although medical treatment may also be considered. However, surgery is recommended when all available medical therapies have been ineffective. In this case, we report a secondary duodeno-colonic fistula due to Crohn`s disease that was temporarily managed by an endoscopic procedure with a detached endoloop and hemoclips as a bridging therapy to final surgical repair.

The purpose of this study are to develop a SDSS (Spatial Decision Support System) that can incorporate diverse opinions of stakeholders related the designation of protected areas (PA), and to employ the model for the readjustment of the boundary line of the Jirisan National Park of Korea. The SDSS would lead to more rational and less controversial decision-making during the expansion or removal of PA in Korea. Research methods are as follows. Firstly, to select evaluation criteria for SDSS for PA designation by using expert interview and literature survey. Secondly, to measure their preferences on the designation of additional PA or the removal of a part of PA based on the opinions of various stakeholders such as local residents, environmental groups, or public officials. Thirdly, to produce conservation priority maps based on a multi-criteria decision making technique. The SDSS would be used to rational decision making for the expansion of PA or the release of a certain part of PA by reflecting diverse preferences on biodiversity conservation and economic interest of residents. The visualization of conservation priority maps would also increase the efficiency of such decision making processes. The evaluation criteria for the expansion of PA for biodiversity conservation includes vegetation conservation value, wildlife conservation value, and the habitats of key species. The evaluation criteria for the removal of PA includes the proximity to roads and the boundary of PA, land use types, and conservation zoning of the PA. Preference weights are based on data collected from the Jirisan National Park. Both the conservation priority and removal priority maps are based on land parcels so that property rights of all parcels would be correctly represented.

Body condition score (BCS) is a useful management tool for distinguishing differences in nutritional needs of cows in the herd. Although it is not always possible to quantify the nutrient content of the feed supplied to the donor cow, the nutritional status can be determined by the BCS. The objective of this study was to evaluate in vivo embryo production, return to estrous of donor and pregnancy rate of recipients following BCS in Hanwoo superovulation. Sixty nine Hanwoo donor cows were flushed on day 7 of estrus cycle with same FSH and artificial insemination by the same technicians. Embryos were recovered on 7 days after the third insemination by flushing the uterus with Embryo Collection Medium. The results obtained were as follows: No differences were observed in the efficiency of superovulation rates regardless of BCS (≤2.0, 2.5 to 3.0, and ≥3.5). The mean number of total embryos was each 5.20±0.86, 11.56±1.04, and 6.23±1.07. The mean number of transferable embryo from ≤2.0, 2.5 to 3.0, and ≥3.5 of BCS was 2.60±0.87, 7.94±0.89, and 4.75±1.32, respectively (p<0.05). Return to estrous regardless of donor BCS was no difference. The pregnancy rates of recipient were BCS ≤2.0 11.76%, 2.5 to 3.0 40.79%, and ≥3.5 11.11%, following transfer of fresh embryos produced in vivo, respectively. These results indicate that if the Hanwoo with BCS 2.5 to 3.3 are used for donor and recipient, the embryo production and the conception rate will be greater.

국립공원은 주로 산악 지형 내 조성되어 있으므로 산사태에 의한 피해 가능성을 항상 내포하고 있다. 본 연구는 산사태 연구의 일환으로 국립공원 탐방로 내 위험 급경사지를 체계적으로 유지관리하기 위한 방안을 마련하는데 목적이 있다. 국립공원에 특화된 자체 체크리스트를 제작하였으며, 전국 19개 국립공원 183개소 급경사지에 대한 실태조사가 이루어졌다. 실태조사의 최종 목적은 위험 급경사지에 대한 안정화 대책을 마련하는 것으로 현장조사와 안정해석의 과정을 거친다. 일부 급경사지에서는 위험성 판단을 위해 지상라이다 등 특수 장비를 이용한 조사를 시도하였다. 중장기 정비계획을 위한 투자우선순위 공식을 개발하였으며, 현장자료를 이용한 순위 및 위험등급을 산출하였다. 최종적으로 위험 급경사지의 향후 체계적인 관리를 위해 “국립공원 급경사지 유지관리시스템”을 개발하였으며, 모든 현장자료들은 시스템 내 DB화 되었다. National parks, which are located mainly in mountainous areas, are always at risk of damage by landslides. The goal of this study is to establish a method for systematically maintaining hazardous steep slopes along trails in national parks. We produced a checklist suitable for each of the 19 national parks nationwide and investigated 183 slopes. The aim of these investigations is to recommend appropriate slope-stability countermeasures, including field investigations and stability analysis. We made preliminary investigations at specific sites, evaluating the slope hazard using specialized equipment such as terrestrial LiDAR. An investment priority formula was developed, and ranking and hazardous grades were calculated as part of a long-term maintenance plan. Finally, to systematically manage dangerous slopes and to house all the field data within one system, we developed the “Slope Maintenance System in National Parks” based on web server that can show various information for slopes.
