Recently, the earthquakes activities are more of frequency occurred in the country. In case of nomal or large magnitude earthquakes, which cause a rising number of life loss or widespread loss of property. It must be considered how to cope with the situperty of dpmage in the country ty account of ay earthquake. Consequently, the public works have currently ensured against a lot of risk about seismism not only on large scale structures but also relatively small structures. Therefore, in this study, in order to make the seismic stability safe, it has been evaluated by the seismic performance for caisson-type breakwater. The seismic response analyses have conducted on the caisson-type breaker under long-period, short-period and artificial seismic wave. The liquefaction potential of the foundation, which is caisson-type, is also estimated by using the simplified assessment method. Finally, the result of the numerical analysis by PENTAGON 2D finite element method(FEM) program are presented for 3 cases with time-history seismic analysis under the seismic load.

It has been well known that indiscriminative use of pesticides contaminates water resources and soil to break down the balance of natural ecosystem and brings acute when spray. In this country, 62,602 tons of pesticides were used in 1974 for agricultural purpose figuring 28.0 kg per hectare which showed 20% increasement every year since 1970. It is almost impossible to figure out incidence and mortality of acute pesticide poisoning exactly. However, a survey in 1974 reported that 33.5% of male and 32.7% of female who sprayed certain pesticides complained of several symptoms seemed to be due to acute pesticide poisoning. It also mentioned that the main cause inducing poisoning supposedly was dusting without protective armamation such as masks, booths, gloves and others in more than 60% of above cases. Pesticide poisoning through contamination of food or direct inhalation and contact. With the reason, the followings can be recommended to minimize or prevent pesticide hazards. 1. Strict legal control 2. Systematic education on the safe handling way of pesticides for the people who are to use them. 3. Remarkable warning at transportation and stocking of pesticides. 4. Obligatory attachment of explanation on the package about effect, safe handling method, and. emergency care at acute pesticide poisoning concerned.

지난 2005년 부산의 한 초등학교에서 시작된 "스쿨폴리스"제도가 그 효과를 인정받아 전국의 초등학교에 적용되고 있다. 하지만 스쿨폴리스 제도만으로는 부족한 인력을 확보하기 위해서 배움터지킴이 제도로 확대되었음에도 불구하고 국내에서는 2010년과 2011년에 잊지 못할 충격적인 초등학생 자살사건이나 성폭력 사건들이 교내에서 발생하고 있는 실정이다. 이와 같이 초등학교에서 고학년이 되는 4학년부터 중학교 1학년 학생들의 범죄에 대한 노출과 자살, 집단 따돌림 등의 문제가 심각하게 발전하는 현실을 감안해 전 국가 차원의 문제 해결책이 반드시 필요하다. 하지만, 인력, 공간, 기술, 정서적으로 총체적인 해결책을 제시하여야 함에도 불구하고 지금까지는 개별적인 피해 학생의 부모와 학생 당사자만의 문제로 여겨지고 사회에서 크게 관심을 얻지 못해 그 해결이 미온한 편이다. 그러므로 본 논문에서는 초등학생 범죄의 가장 큰 공간을 차지하는 학교 교실 내부에서 학생들이 자주 사용하는 스마트-폰의 특정 앱과 학교 내부의 홈페이지에 게시되는 글들을 분석하여 학생들이 집단 따돌림이나 자살, 폭력 사건 등이 발생하기 전에 이를 학부모, 학내에 근무하는 배움터지킴이, 선생님에게 안내함으로써 사고를 미연에 방지할 수 있는 시시스템을 제안하고자 한다. 우리가 제안한 시스템은 안드로이드 기반의 스마트-폰에서 동작하도록 설계되었으며, 모바일 웹 기술을 접목하여 교내 홈페이지 게시판에 게시되는 글들에 대한 모니터링을 통해서 보다 학생들의 심리, 정신, 건강 상태 등에 대해서 알아볼 수 있도록 설계하였다.

To examine the parenting experiences of North Korean parents in South Korea, seven parents(a father, a grandmother and five mothers) were interviewed about their parenting beliefs, attitudes and behaviors. It was found that parents from North Korea felt a safe existence including safety from hunger in South Korea but they were afraid of the many cars and unfamiliar diseases in South Korea. They had many difficulties with unfamiliar child rearing practices and parental roles in South Korea. Their confusion about good parenting was compounded by psychological and physical after-effects of the escape from their native country. They found help in adjusting to parenting in South Korea by such social networks as child care centers.

A safe and secure civil aviation system is a critical component of the nation's overall security, physical infrastructure, and economic foundation. Although it is not fully known at this time what actually occurred or which of the weaknesses in the nation's aviation security apparatus contributed to the terrible events of 11 September in the U.S.A., it is clear that serious weaknesses exist in our aviation security system including regulation system. Actually, defectiveness of regulations structure and contents concerned in aviation security were discussed in various studies. On this study, we have identified defectiveness in aviation security regulation system by the comparative study between 14 CFR and Korean regulations. Finally, we are to provide some suggestions and alternatives to improve aviation security regulation system in this country.

Earthquakes of M5.1, M5.8 and M4.5 occurred in September 12 and 19 respectively in Gyeongju, Gyeongbuk Province. Theses earthquakes inflated fears of people and highlighted necessity of detailed countermeasures because we have considered our country is safe to earthquakes. In the meanwhile, earthquake also impacts groundwater and thus it was recently reported that the Gyeongju Earthquakes affected groundwater there. This study evaluates daily groundwater data collected from five national groundwater monitoring stations (Geoncheon, Sannae, Oedong, Yangbuksin, Cheonbuk) in Gyeongju. The analysis revealed that only groundwater level of bedrock monitoring well hosted in andesite exhibited earthquake impact while no wells in the other four stations hosted in sedimentary rocks showed substantial responses to the earthquakes. This may be derived from the difference of seismic velocity of hosting rocks as well as epicenter distance. Special interest on groundwater monitoring is required to predict earthquakes as precursory phenomena.

This paper deals with investigation on the spot for grounding systems of buildings based on international standards at construction sites. The investigation was carried out for grounding method, grounding type, shape of grounding electrode, grounding for a lightning protection system, continuity of steelwork in reinforced concrete structures, etc. The investigation on the spot was performed by a researcher and engineer with over fifteen years of industry experience all over the country. As a result of the investigation on the spot in 13 buildings, common grounding and structure grounding methods were dominant. The safety improvement methods include installation of equipotential bonding conductors for the connection to the main earthing terminal, equipotential bonding conductors for supplementary bonding, use of Surge Protective Devices (SPD), and safe connections between earthing conductors and the rebar.
