On a farm with 6 Korean beef cattle, an adult cow and a calf suddenly died while eating. At that time, hair was pressed upon the stanchion facilities where the adult cow was fed. Two dead cattle were submitted to the Animal and Plant Quarantine Agency for disease diagnosis. Grossly, the mouth of the adult cow was full of feed that had been eaten before death, and there was a foamy fluid in the calf's trachea. Both hemorrhages were observed in the muscles, as well as in the internal organs such as the liver, lungs, and heart. Ruminal mucosa was easily peeled off. Histopathologically, both muscles and internal organs showed severe hemorrhages. In particular, affected muscles were shown segmental and band-like patterns of myonecrosis, disappeared some myocytes, burned hair follicles, and irregular surface of skin. Severe hemorrhages of muscles and internal organs were consistent with previous reports. Easily separated mucosa of rumen and muscle lesions were very characteristic. We determined electrocution according to the pathological findings, laboratory results, and traces of accidents. This report will help to understand of pathological lesions of electrocution. Furthermore, this case suggests that the electrical wires and devices must be installed and handled carefully during the construction of the cowsheds care.

The object of this paper is to correct check the tree situation and quantity around highway. Also, those data utilize in order to establish plan about how to the long and short term landscape construction and maintain program. The result of this study can be summarized as follows; 1. Tree decrease rates for 8 branch offices were Jongbu(5.62%), Gangwon(4.32%), Chungcheong (3.35%), Honam(5.62%), Gyeongbuk(3.06%), Gyeongnam(5.60%), Seorak training center(0.31%), Headquarter(1.54%). Also decrease causes were traffic accidents(1.8%), air po11ution(4.7%), humid damage(0.9%), insect and disease(1.2%), wind and rainfall(3.4%), dry damage(3.5%), cold damage (1.0%), fire(3.1%), damage of the man and anima1(4.1%), remove bad tree(13.1%), bad rooting(9.5%) and etc.(53.7%). 2. Improve methods of tree death problems were regulation management(ferti1ize, irrigation and pesticide work), improvement of draining system, Pull out the weeds, Plant native plants, utilize organic matter fertilize and plant environment trees.

In this study, we analyze the current status of major disasters in distribution works and propose safety measures through the distribution live-line work method and electric shock risk assessment. The result of analyzing the ratio of electric shocks to the occurrence of industrial accidents in the recent 13 years shows that the death rate is higher than other industries, especially the construction industry occupying most of the disaster, and it is higher than the collapse disaster. We analyze statistic data of 101 victims selected as core words of live work, distribution line, pole and 22.9 kV in the investigation report of major accident of electric shock fatal from 2001 to 2014. The safety measure was established through the risk assessment of the distribution method using the standard model of the risk assessment based on the results of electric shock analysis on the distribution line. In order to prevent the electric shock accident which is recently being discussed, the risk assessment procedure were carried out in the above-mentioned 22.9kV special high voltage live-line operation method. We derived the risk reduction plan for the distribution line from the results of the major accidents statistic and demonstration of the line works.

산소를 추진제로 사용하는 발사체를 발사하기 위한 발사대 및 그것을 시험하기 위한 설비를 보유하고 있는 건물은 언제나 누출된 산소로 인한 화재 및 폭발의 위험성을 지니고 있다. 또한 질소, 헬륨 등과 같은 각종 고압가스류를 사용하고 있기 때문에 밀폐된 공간에서의 가스 누출로 인한 질식사의 위험에도 노출되어 있다. 따라서 이러한 공간 내의 공기 중 산소 농도를 관리하여 발생할 수 있는 사고를 미연에 예방할 수 있어야 한다. 본 논문에서는 산소 농도 관리의 방법과 시스템 구성 및 적용 결과를 정리하였다.

국내 한랭지역(강원권)의 경우 낮은 연평균 기온으로 인해 도로표면이 자주 결빙된다. 특히 터널의 입출구의 도로면은 지형적 영향으로 그늘이 생기기 때문에 타 도로면에 비해 결빙이 많이 발생하게 된다. 이러한 결빙을 방지하기 위해 염수분사장치, 전열선 설치, 지열이용 등이 주로 사용되고 있다. 하지만 이런 방법들은 환경오염, 많은 공사비, 유지보수비 및 정기적인 점검 등의 문제점들이 있다. 본 연구에서는 기존도로의 결빙을 방지하기 위해 발열체인 CNT를 이용하여 콘크리트 슬래브의 발열효과를 살펴보고 최적의 CNT설치 간격을 결정하였다.

The whole death by disaster is totalized to 1,515 person from 1993 to 2004 year in our country. In this section life damages by landslide is totalized 357 people(about 24% of whole life damage). About 36 people are died by landslide(such as cutting area failure every year). Kangwon-do need a lot of interests and prevention because dangerous area that landslide occurrence is more than other area at summer localized downpour or thawing season and there is landslide occurrence possibility area more than other area. Kangwon-do area is higher than other area in natural disaster incidence and damage scale because topography and a lot of rainfalls by summer localized in Kangwon-Do than other area. In this study, dangerous area of landslide occurrence possibility is analyzed and compared Kangwon-Do with other areas in our country. as a result, every year we have experienced landslide occurrence and natural disaster. accordingly, we urgently need to prevent landslide occurrence and natural disaster by analy-zed source about landslide occurrence and condition of disaster in Kangwon-Do and suitable engineering method and construction work.

The traditional ritual foods of Korea have developed with for many years, and differ by locality, family customs and religious characteristics. In an efforts to establish the database on that addresses the difficult issue of a classification system for traditional Korean foods, we have conducted a survey of a traditional Korean ritual foods. In the database, typical 10 rites are represented, covering birth to death, these are birth, the hundredth day after birth, the first birthday, the commemoration of finishing books(graduation), the coming of age ceremony, marriage, the birthday feast for an old man, the 60th wedding anniversary, the funeral, and the memorial service. For each rite, the appropriate traditional Korean foods are classified into 6 categories-main dishes, side dishes, tteok lyou, hangwa lyou, eumchung lyou and the others. Some of these have varied considerably with the passage of time, and some have since disappeared. This database provides a basis for generational transmission, preservation and development of traditional Korean ritual foods as one of the components traditional Korean culture.

Due to the development of technology, there is a considerable increase in the number of skyscrapers in the world. Accordingly, there are rapid growing requests about maintenances such as cleaning, painting, and inspection. However, it is extremely dangerous working the walls of buildings, and crashes from buildings have accounted for large proportion of constructional accidents. Especially, as the number of buildings with irregular shapes increases, the accident rate during the maintenance work increases each year, and most of the accidents lead to death. An alternative solution must be developed with the commercialization of automatic systems. In this research, a fundamental research has been conducted for drafting and commercializing an automation tool that is carried in the built-in guide system, which can perform cleaning.

범죄는 사전적 예방이 중요하다. 과거 범죄는 사후적으로 대처하고 이를 처벌하는데 집중하였다. 그러나 빅데이터 기술을 적용하면 범죄는 사전적으로 예방될 수 있다. 빅데이터는 범죄자 또는 잠재적 범죄자의 행동을 예측할 수 있기 때문이다. 이 글은 범죄예방을 위해 빅데이터 시스템을 어떻게 구축할지에 대해 논의한다. 구체적으로는 빅데이터의 비정형 데이터와 기본의 정형데이터를 결합하는 방식을 다루고 그 결과로서 범죄예방시스템을 설계한다. 이 연구를 통해 범죄 예방을 위해 빅데이터가 활용되는 가능성을 지문을 통해 기술하였고 이를 기초로 향후 범죄예방프로그램 및 연구에 도움을 줄 것으로 기대된다.

Geum'yeok-dang house in Andong was originally constructed in 1558. The original floor plan of the upper base featured a 90-degree tilted '日' shape, and had inner court(內庭) on each side of 'Jungdang(中堂, center hall)' building that was placed on the south-north axis. When designing the building, the Neo-Confucian client of Geum'yeok-dang applied his understanding of how Ga'rye("家禮") defined the structure of ritual space. Consequently, 'Daecheong(大廳)', the place where guests were greeted and ancestral rites and coming of age ceremonies for male were held, was built in a protruding fashion. 'Jungdang'[otherwise known as 'Jeongchim(正寢)'], where coming of age ceremonies for females were held, the master of the house faced death, and memorials for close ancestors were held, was placed at the center of the residence on the south-north axis. The Geum'yeok-dang today was greatly renovated in the early and mid 18th century, due to the spread of 'Ondol' heating system. As the Ondol heating system became popular, the pre-existing drawbacks and the inconvenience of the house stood out clearly. As a result, the house was renovated into today's structure consisting of '口' shape 'Anchae' and 'Daecheongchae' in separate building.
