  • 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.

  • Test and launch facilities which use oxygen as the propellant of a launch vehicle have hazards of fire and explosion by the leakage of oxygen. Also, the personnel operating the facilities, which use the high-pressured gases like nitrogen and helium in the closed room, is exposed to the hazard of death from suffocation. Consequently, we should keep out of the hazards and the accidents by monitoring the contents of oxygen in the air. The method and the system construction for monitoring oxygen contents in the air and the results from its application to Naro space center are described on this paper.

  • In the cold region, road surface is frequently frozen, resulting in property/facility damage as well as people's death. In order to prevent the road surface from being frozen, conventional deicing methods such as salt, geothermal, and electric wires have been widely used. However, theses methods have some problems such as anti-environment, high-construction and -maintenance cost and so on. To improve the drawbacks of aforementioned methods, carbon nanotube (CNT) was used as an heating material in the laboratory test. Through the test, heat transferring effect of CNT on the concrete slab was investigated and maximum interval of CNT installation was determined.

  • 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.

  • Proactive prevention is important for crime. Past crimes have focused on coping after death and punishing them. But with Big Data technology, crime can be prevented spontaneously. Big data can predict the behavior of criminals or potential criminals. This article discusses how to build a big data system for crime prevention. Specifically, it deals with the way to combine unstructured data of big data with basic form data, and as a result, designs crime prevention system. Through this study, it is expected that the possibility of using big data for crime prevention is described through fingerprints, and it is expected to help crime prevention program and research in future.

  • 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.

  • Since construction of the estuarine barrage at the mouth of the Nakdong River, eutrophication and increased abundance of phytoplankton have occurred mainly due to the increased retention time in the reach. However, during the spring, there is a decrease in chlorophyll-a, as a result of an increase in zooplankton number, which preys upon phytoplankton and affects the value of chlorophyll-a. In order to emphasize the importance of zooplankton data in water quality simulation, zooplankton community data were used to simulate water quality and eutrophication at Mulgeum located in 27 km upstream from the barrage. WASP 7.2 was used as the water quality model for the river, using a monthly data set from 2003 to 2005 for model calibration and verification. The results showed that chlorophyll-a, DO, and total nitrogen in the river were simulated well during the verification period. The results of water quality simulation using zooplankton community data in the model were better than those with phytoplankton death rate, in terms of the absolute value of percent bias, root mean square error, and Nash-Sutcliffe efficiency. Those results indicate the use of zooplankton data provides more accurate simulation results for chlorophyll-a and eutrophication.
