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.

Extension of Lance Life by Change of Height of Lances in the Smelting Furnace of Mitsubishi Process

Sung‑Mi Lim,Soo‑Sang Park,Kyung‑Woo Yi 대한금속·재료학회 2021 METALS AND MATERIALS International Vol.27 No.10

A Mitsubishi process, which pertains to continuous Cu production, involves a smelting furnace, cleaning furnace, and convertingfurnace connected in series. One of the main issues pertaining to the smelting furnace is the frequent interruption ofoperations required to allow the inspection and replacement of lances, because lances are frequently fractured. The presentstudy was aimed at modifying the operating conditions of the smelting furnace to suppress lance fractures. A numericalmodel was developed to simulate the transport phenomena in the furnace, including multi-phase behaviors. The simulationresults showed that the lances were exposed to a severely erosive atmosphere with high temperatures. Further calculationindicated that raising the positions of the lances could lower the temperature of the lances, and reducing the occurrence ofsplashed melt, which contains erosive sulfides. The smelting furnace was operated under the conditions of the raised lanceheight and attentively monitored for several months. It was confirmed that by implementing such a change of the lanceheights, the occurrence of lance failures has been considerably reduced without notably affecting the reaction ability of thesmelting furnace.

Tuberculosis risk is associated with genetic polymorphisms in the LRP2, CUBN, and VDR genes

Background Vitamin D (Vit. D) is used extensively during tuberculosis treatment. Low levels of serum Vit. D increase the risk of active tuberculosis development. Altered expression of the proteins involved in Vit. D metabolism impairs cathelicidin production, thereby increasing the host susceptibility to tuberculosis. Objective We are trying to investigate whether single nucleotide polymorphisms (SNPs) in LRP2, CUBN, and VDR genes could afect tuberculosis development. Methods We included participants of the Korean Association Resource (KARE), part of the Korean Genome and Epidemiology Study (KoGES), and used their recorded data. A total of 8840 people (4182 men and 4658 women) were eligible subjects. The 5-kb regions from the ends of transcripts of GC, LRP2, CUBN, and VDR genes were amplifed to select 13, 47, 70, and 15 SNPs, respectively. For association analysis and statistical analysis, PLINK version 1.07 and PASW Statistics version 18.0 were used. Results Signifcant correlation was observed in 11, 2, and 1 SNPs in LRP2, CUBN, and VDR genes. The efect of rs6747692 of LRP2 on transcription factor binding was confrmed using RegulomeDB. We confrmed that rs2239182 of VDR is located in the genomic eQTL region and can afect transcription factor binding and gene expression. Conclusions Genetic polymorphisms in genes encoding proteins involved in Vit. D metabolism infuence immune system components. Therefore, such polymorphisms may infuence the susceptibility to Mycobacterium tuberculosis invasion and alter the defense mechanisms against Mycobacterium tuberculosis infection. The correlation between genetic variation and tuberculosis development can provide new guidelines for the management of tuberculosis.

박상수(Sang-Soo Park),심미령(Mi-Ryung Sim),이충기(Chung-Ki Lee) 한국경제연구학회 2017 한국경제연구 Vol.35 No.3

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.

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.

유통중인 즉석섭취 새싹채소와 샐러드의 세균오염 분석

강태미(Tae-Mi Kang),조선경(Sung-Kyung Cho),박지용(Ji-Yong Park1),송경빈(Kyung-Bin Song),정명수(Myung-Soo Chung),박종현(Jong-Hyun Park) 한국식품과학회 2011 한국식품과학회지 Vol.43 No.4

즉석섭취편이 식품중 신선편의식품(fresh-cut-vegetable)인 새싹 채소와 샐러드의 수요는 급증하고 있으나 특히 새싹채소의 미생물 품질평가를 위한 자료가 거의 없는 상황이다. 따라서 국내 대형할인마트에서 유통중인 새싹채소 50제품, 샐러드 30제품을 수집하여 총 호기성균, 대장균군, E. coli, Salmonella spp, S. aureus, B. cereus, L. monocytogenes, Cam. jejuni, C. perfringens의 오염연구를 수행하였다. 총 호기성균은 새싹채소에서는 7.95 log CFU/g 검출되었으며 샐러드에서 평균 6.70 log CFU/g검출되어 샐러드 보다 새싹채소에서 약 1 log CFU/g 더 높게 검출되었다. 대장균군은 새싹채소에서 6.69 log CFU/g 검출되었고 샐러드에서 평균 5.42 log CFU/g 검출되었다. E. coli은 새싹채소 50제품 중 16제품(32%)에서 2.38 log CFU/g으로 검출되었고 샐러드 30제품 중 8제품(27%)에서 2.21 log CFU/g으로 검출되었다. B. cereus는 새싹채소 50제품 중 16제품(32%)이 검출되었고 샐러드 30제품 중 16제품(53%)가 검출되었으나 대부분이 3 log CFU/g 이하의 검출율을 보여 주었다. Salmonella, S. aureus, L. monocytogenes, Cam. jejuni, C. perfringens는 검출되지 않았다. 그러므로 분석된 새싹채소와 샐러드에서 B. cereus이외에 다른 식중독 병원성 미생물의 위해 가능성은 크지 않은 것으로 보인다. 그러나 총 세균수가 높게 검출되었고 위생지표세균인 대장균의 검출율이 높아서 이들 식품의 미생물 안전성을 확보하기 위해서 보다 더 철저한 생산유통관리가 요망되며 특별히 새싹채소에 대한 미생물안전성 확보에 대한 노력이 요구된다. Although bacterial outbreaks from ready-to-eat foods have increased, little information is available on microbial quality of sprouts in markets. Fifty sprouts and 30 salads were collected from wholesale markets. Total aerobic count (TAC), coliform, Escherichia coli, and some pathogens were detected. TAC for sprouts was 7.95 log CFU/g and 6.70 for salads, indicating that sprouts were more contaminated by 1 log CFU/g than that of salads. The numbers of coliform were 6.69 log CFU/g for sprouts and 5.42 for salads. E. coli was detected in 16 of 50 sprout samples at 2.38 log CFU/g and eight of 30 salads at 2.21 log CFU/g. Bacillus cereus was detected in 29 of 50 sprout samples and 16 of 30 salads, and the counts were mostly <3 log CFU/g. Salmonella, Staphylococcus aureus, Listeria monocytogenes, Campylobacter jejuni, and Clostridium perfringens were not detected. Therefore, although pathogens may not be a high risk for these foods, the high TAC and E. coli contamination require improved production and distribution methods, particularly for sprouts.
