There are 4 marine national parks in Korea, Hanryohaesang national park, Taeanhaean national park, Dadohaehaesang national park and Byeonsanbando national park. The total area of these park is 3,332.85㎢ that is 50.07% of the total area of all national parks in Korea, 21 site including mountain etc,. the areas exclusive land(mountain) is 2,753.709㎢ that is 40.9% of the total areas of all national parks in Korea. KNPS has been monitoring about the coastal wetland including mudflat and costal sanddune on 4 marine national park, and identified the total 105 site, 19 site of hanryohaesang national park, 35 site of Taeanhaean national park, 49 site of Dadohaehaesang national park and 2 site of byonsanbando national park and the area of 17.2㎢. This is 0.69% of the total area of mudflat in Korea and 7.8% of mudflat designated protected area in Korea. and also total length of shoreline is 1,729km that is 12% of the total length of shoreline in Korea. However, There is many unexplored coastal zone compared to the long shoreline. so, KNPS will start to research in-depth using technical equipment, for example, drone with camera for measurement, mutispectral scanner, liDAR(light detection and ranging) kinds of 3D scanner for ground, VRS/RTK GPS etc, for studying on the effective coastal zone information research system through precision surveying in 2017. And then, KNPS will carry out to expanding, restoring, monitoring and providing visitor service on special protection area of coastal zone. Precision survey results Increased from 17 square kilometers to 93 square kilometers in protect area

The effects of Mn and C content on the age hardening of Fe–Mn–Al–C lightweight steels, which have austenitic or duplex(austenite and ferrite) microstructures, were investigated. An increase in Mn content induced a delay of the age hardeningthat is caused by the formation of intra-granular κ-carbides. In order to interpret the effect of Mn content, first-principlescalculations were conducted using the supercells of Fe24Al8C8,Fe24Al8C7,Fe24(Al7Mn)C8, and Fe24(Al7Mn)C7. The calculationsshowed that an increase in Mn content could be the source of the delay of the intra-granular κ-carbide formation bysuppressing C atom’ occupation of the vacancy at the body-centered site of L12. An increase in C content accelerated theformation of intra-granular κ-carbides, which induced the intense age hardening, and coarse inter-granular κ-carbides, whichresulted in significant decrease in impact absorbed energy due to inter-granular fracture.

Under the Suryong dictatorship, by definition, there is no political completion for Suryong`s status. There are, however, horizontal competitions to expand power and interest carried out by major power organizations and elites. Apparently they are loyalty competition devoted to the Suryong. During the power succession, as the ruling coalition is reconstructed, they intensify themselves. Two features have been pronounced during the hereditary succession from Kim Jong-il to Kim Jong-un in regard to competition for power and interest among power organizations and elites: the one is the competition for regency, i.e. to advance oneself as the dominant force in the promotion of the power succession; the other is the competition for increasing share of power and interest by power organizations and elites. Jang Sung-taek has stood in the center of these two competitions and he was purge thereof.

본 연구는 차량 주변을 지능적으로 감시하는 자동차 주변 감시시스템에 관한 것으로, 자동차의 주행 및 주차 시 속도의 변화나 운전자의 요청에 의해 자동차 주변 지역에 관한 시야를 상황에 따라 달리하여 모니터링 함으로써 운전자가 안전한 주행 및 주차를 수행할 수 있게 하기 위한 것이다. 그러한 목적을 달성하기 위하여 본 연구에서는 차량의 주변부를 감시하기 위하여 차량의 외곽에 설치된 카메라의 각도가 지면으로부터 차량의 상부를 향하는 방향으로 변경될 수 있도록 제어하는 제어부, 카메라의 영상을 입력받아 차량주변의 영상을 생성하는 영상처리모듈, 영상처리모듈에서 생성된 영상을 출력하는 디스플레이를 포함하는 것을 특징으로 하는 지능형 자동차 주변 감시시스템을 제안한다. This study is on a vehicle surroundings monitoring system, which enables a driver to travel and park safely by monitoring vehicle surroundings, depending on the speed of vehicle and driver's control when traveling and parking. To achieve the aforementioned purpose, we propose an intelligent vehicle surroundings monitoring system, which consists of a control part, an image processing module and display module. Hence, the control module controls angle of camera to turn upward from the bottom to monitor vehicle surroundings. The image processing module merges the received images from cameras with the original vehicle image to display the vehicle’s surroundings in real time as if looking down from the sky.

Background GBA1 mutations are the most common genetic risk factor for development of Parkinson’s disease (PD). The loss of catalytic activity in GBA1, as well as the reduction of the GBA1 protein in certain cellular compartment, may increase disease progression. However, the mechanisms underlying cellular dysfunction caused by GBA1 deficiency are still mostly unknown. Objective In this study, we focus on the genetic interaction between GBA1 deficiency and PD-causing genes, such as DJ-1, in mitochondrial dysfunction. Methods GBA1 knockout (KO) SH-SY5Y cells were used to assess DJ-1 functions against oxidative stress in vitro. The levels of cellular reactive oxygen species were monitored with MitoSOX reagent. The expression of the PARK7 gene was analyzed using the quantitative real-time PCR (qRT-PCR). To understand the mechanism underlying DJ-1 upregulation in GBA1 KO cells, we assess ROS levels, antioxidant protein, and cell viability in GBA1 KO cells with treatment of ROS inhibitor N-acetyl-cysteine or miglustat, which is an inhibitor of glucosylceramide synthase. Dopaminergic degeneration was assessed from Gba1 L444P heterozygous mice mated with Park7 knockout mice. Results We find that DJ-1 is significantly upregulated in GBA1 KO cells. Elevated levels of DJ-1 are attributed to the transcriptional expression of PARK7 mRNA, but not the inhibition of DJ-1 protein degradation. Because DJ-1 expression is highly linked to oxidative stress, we observe cellular reactive oxygen species (ROS) in GBA1 KO cells. Moreover, several antioxidant gene expressions and protein levels are increased in GBA1 KO cells. To this end, GBA1 KO cells are more susceptible to H2O2-induced cell death. Importantly, there is a significant reduction in dopaminergic neurons in the midbrain from Gba1 L444P heterozygous mice mated with Park7 knockout mice, followed by mild motor dysfunction. Conclusion Taken together, our results suggest that DJ-1 upregulation due to GBA1 deficiency has a protective role against oxidative stress. It may be supposed that mutations or malfunctions in the DJ-1 protein may have disadvantages in the survival of dopaminergic neurons in the brains of patients harboring GBA1 mutations.

김영훈(Kim, Young-hun),장성호(Jang, Sung-Ho),박윤기(Park, Yun-Ki) 용인대학교 무도연구소 2012 武道硏究所誌 Vol.23 No.1

이 연구는 역대 YMCA 체육을 토대로 하여 구체적으로 살펴보고자 한다. 이에관해 생활체육 활성화 방안 모색을 제시하는데 논의 및 결론을 도출하였다. 이는 다음과 같이 확인할 수 있다. 첫째, 한국에서의 YMCA운동은 1899년 경성에서 선교활동을 시작되었다. 둘째, YMCA의 전인교육정신인 지(智)·덕(德)·체(體)의 정신과 통하는 정신으로서 비폭력, 민주주의의 실천교육과 상통하는 정신이었다. 셋째, 이상재의 교육사상은 인간의 본질적인 면에 치중하여 올바른 인격체로 양성하는 것으로 지·덕·체의 전인적 교육이었음 알 수 있었다. 넷째, 서울 YMCA의 창립과 역사적 배경을 보면 서울YMCA는 1903년 10월 28일 창립하였다. 다섯째, 서울YMCA를 도입, 회원들에게 지도한 스포츠로는 야구, 농구, 배구, 축구, 유도, 검도, 체조 등이 있었다. 이상과 같이 종합해 볼 때, 역대 YMCA 체육의 역사에서 보이듯이 그 정책을 통해 한국생활체육의 활성화를 위한 방안 모색에 따른 정체성을 제시할 수 있는 것이다. This research is looked at concretely is based on the generation of YMCA physical training. It derive a discussion and conclusion to grope a plan to activate living physical training. This can be confirmed by the following essay. First, the YMCA exercise in Korea started in Gyeong-sun, 1899 as a missionary activity. Second, the mind of former education of YMCA’s just·morality·formality was a mind connected to the communicating with anti-violence, democratic practice education. Third, Lee Sang-Jea’s educational method is to bring up the personality to the right side valued on true nature of a human being, which indicates that his educational method is for the whole man. Fourth, looking at the foundation and historical backround, Seoul YMCA was established on 28th October 1903. Fifth, sports that Seoul YMCA guided to members were baseball, basketball, volleyball, football, judo, kendo, gymnastics etc. To round up all the above statements, the identity following a plan to activate Korea living P.T can be derived through the policy as seen in YMCA physical training’s history in generations.

플라즈마 정보인자를 활용한 SiO₂ 식각 깊이 가상 계측 모델의 특성 인자 역할 분석

장윤창,박설혜,정상민,유상원,김곤호,Jang, Yun Chang,Park, Seol Hye,Jeong, Sang Min,Ryu, Sang Won,Kim, Gon Ho 한국반도체디스플레이기술학회 2019 반도체디스플레이기술학회지 Vol.18 No.4

We analyzed how the features in plasma information based virtual metrology (PI-VM) for SiO2 etching depth with variation of 5% contribute to the prediction accuracy, which is previously developed by Jang. As a single feature, the explanatory power to the process results is in the order of plasma information about electron energy distribution function (PIEEDF), equipment, and optical emission spectroscopy (OES) features. In the procedure of stepwise variable selection (SVS), OES features are selected after PIEEDF. Informative vector for developed PI-VM also shows relatively high correlation between OES features and etching depth. This is because the reaction rate of each chemical species that governs the etching depth can be sensitively monitored when OES features are used with PIEEDF. Securing PIEEDF is important for the development of virtual metrology (VM) for prediction of process results. The role of PIEEDF as an independent feature and the ability to monitor variation of plasma thermal state can make other features in the procedure of SVS more sensitive to the process results. It is expected that fault detection and classification (FDC) can be effectively developed by using the PI-VM.

Uterine arteriovenous malformations are very rare but potentially life threatening lesions. These lesions may be congenital or acquired, but especially occur in patients with a history of curettage, abortion or pregnancy. Color doppler ultrasonography is the preferred method of diagnosing of arteriovenous malformations. In many cases, hysterectomies are performed. But if patients want pregnancies, embolization therapy and conservative treatment are effective therapy. We have experienced a clinical case of uterine arteriovenous malformation, which is presented with a brief review of literature.
