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.

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.

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.

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.

This study was conducted to suggest appropriate methods for management of urban forest after investigating the present condition and problems of urban forests by analyzing vegetation and soil properties in urban forests in the Daejeon. On the basis of our research, Pinus rigida dominate Gyejoksan and Bomunsan. Pinus densiflora dominate Wolpyeong park and Quercus acutissima dominate Namsun park. On the basis of our result of analysis of soil chemical properties, all investigated areas have low pHs, available phosphates and exchangeable cations. They indicate that the soil of those areas have been acidifying progressively. Soil hardness measurements were conducted to know the conditions of trampled soils and the results of them show that soil hardness in Namsun park was higher than the others. This indicates that human interference affect the health of the urban forest.
