최근들어 사이버 아파트 붐이 일면서 시들해진 건축 경기에 새로운 바람이 불고 있다. 정보통신부는 이러한 흐름에 맞춰 초고속 정보통신 건물 인증제를 도입 법적.제도적 기초를 마련하였다. 이는 어느정도 요건을 갖춘 건축물에 대해서만 그 자격을 부여한다는 것이 이 제도의 핵심. 아직은 시행초기 단계이지만 향후 많은 건축물이 사이버 건축물로 지어질 것이며 이에 대비하고 불량 건축물의 난립을 방지하는 등 다목적성을 띠고 있다. 이에 정보통신부는 초고속 정보통신 건물에 대한 인증제를 도입해 사업자들의 참여를 유도하고 인증을 받은 회사에게는 인증에 대한 홍보효과로 분양촉진의 효과를, 입주자에게는 정보가 인증하는 건물에 대해 신뢰를 가질수 있게 하는등 다중의 효과를 노리고 있다. 정보통신부의 초고속 정보통신 건물인증제의 구체적인 내용과 인증제에 대한 현대 건설의 사례를 살펴봄으로써 초고속 정보통신 건물인증제에 접근해 보고자 한다.

The purpose of this study is to understand the effect of violence in sports on intention to sport continuance among female athletes and to analysis the mediating effect of depression and the difference groups according to help-seeking. In order to accomplish these purposes, this study surveyed from September to October in 2010. The final subjects in the analysis were 345 female athletes who are belong to school athletic team, professional team, business team, and national team. The data were analyzed with SPSS 18.0 and AMOS 10.0 for conducting multiple group analysis. The main results of this study are as follows; First, those who were suffered by emotional violence were 62.4%; those who are damaged by physical violence were 28.6% among the participants in this study. In case of intention to sport continuance, when measured by a rule of five, was average 3.15. 29.9% of the female athletes scored above the standard of depression. Second, depression turned out to have a partial mediating effect within the relationship where violence in sports has effect on intention to sport continuance. Third, between experimental and non-experimental group on help-seeking among female athletes, there was a statistically significant difference in the structural relationship. This means that help-seeking has moderating effect within the path of violence in sports affecting depression. Based on the results, this study suggested that there is a strong need for intervention for the both prevention and cure of the sports violence. It is necessary to develop preventive programs and coping strategies on female athletes' depression and intention to sport continuance.

Many local governments are reducing speed limits according to the "Safe Speed 5030" policy implemented by the government to reduce traffic accident deaths. In the urban road sections in many metropolitan cities where speed limit reduction is applied as a pilot project, the decrease effect of the traffic accident number and death count is shown; however, no study of the effect analysis on the road sections of medium and small cities (basic local government unit) is found. Therefore, this study investigated the travel speed, number of traffic accidents, and death count before and after the implementation of speed limit reduction, targeting some urban road sections in Pyeongtaek city and some provincial road sections in Icheon city among basic local governments, namely among medium and small cities in Seoul Metropolitan Area.

현재 유통되고 있는 일반백미의 경우 소비자가 밥을 짓기 위해서는 쌀을 씻어야하는 번거로움 뿐만아니라 쌀 중량의 약 15배의 물이 소요되고, 또한 이때 발생된 쌀뜨물이 수질오염의 원인이 되기 때문에 무세미가공 및 보급 필요성이 점차 높아지고 있다. 무세미 가공분야의 선진국인 일본의 경우 ‘92년부터 습식 무세미조제기가 실용화되기 시작, 현재 사다께 등 6개사에서 기계장치를 생산보급 하고 있으며, 무세미의 유통도 일반화되어가고 있는 추세이다. 국내의 경우 무세미조제기는 근래에서야 습식 무세미 조제설비가 국산화되어 보급초기 단계 있으며, 무세미의 안정적 가공 및 보급을 위해서는 앞으로 많은 연구가 이루어져야 할 것으로 생각된다. 특히 습식의 경우 쌀이 물에 접촉하는 시간이 길 경우 품질저하의 우려가 크고, 쌀중량의 1.4배에 해당하는 물이 가공과정에 필요하기 때문에 물사용량을 억제할수 있는 가공기술의 개발 필요성이 커지고 있다. 따라서 본 연구에서는 물사용량을 최소화 할 수 있는 무세미 조제시스템을 개발하고자 하였으며, 주요결과를 요약하면 다음과 같다. 시작기는 연마 및 공기세척부, 정전기 세척부, 미세가수세척부로 구성하여 쌀이 단계적으로 세척될 수 있도록 제작되었다. 성능시험 결과, 각 세척공정별 세척수의 탁도 감소효과는 연마 및 공기크리닝부에서 22.67ppm, 정전기 크리닝부에서 8.33ppm, 미세가수세척부에서 17.34 ppm이 감소되는 것으로 나타났다. 특히 정전기세척부의 탁도감소 효과는 다른 두공정에 비해 작지만 제거가 쉽지 않은 미세한 쌀겨들을 제거하여 탁도를 개선을 시켰기 때문에 미세가수세척장치에서 가수량을 적게 사용하는데 기여한 것으로 판단된다. 가공시 적정 탁도를 확보할 수 있는 가수량은 430cc/kg로 기존의 습식에 비해 약 69%정도 세척수 절감효과가 있었다. 이때 미세가수세척부의 원통스크린 회전수는 108, 205rpm범위가 적정한 것으로 나타났다. 쌀의 품위는 탁도가 가공전 97.33ppm(일반백미)에서 가공후 최대 48.00ppm으로 낮아졌으며, 백도도 가공전 36.80에서 42.80으로 향상되어 씻지 않고도 밥을 지을수 있는 무세미 가공이 가능하였다. 이밖에 쇄립률은 가공전 5.30%에서 7.37%로 다소 증가하는 것으로 나타났고, 함수율은 가공전 15.60%에서 15.80%로 약 0.2%가 증가하였으나 기존의 연구결과에 비춰볼 때 문제가 되지 않을 것으로 여겨진다.

This paper presents the tensile behavior of stud connections installed between reinforced concrete and steel members. Eight specimens are tested to verify the factors influencing the tensile behavior of the connection. Major variables considered in the test are the reinforcement ratios of concrete member and connection details. Test results indicate that the reinforcing bars near stud bolts contribute to the increase of the tensile strength of the member as well as to the reduction of brittle failure. It is shown that C-type or U-type connection has relatively high ductility. From the evaluation on the tensile strength of test results including those of peformed by previous researchers, it was shown CCD (Concrete Capacity Design) method overestimated the strength. In this paper, the reduction factor of 0.75 ø instead of ø is suggested for design purpose of the stud connection.

Most concrete gravity-type dams in and out of the country were constructed by column method to control cracks caused by concrete hydration heat generated during construction, resulting in a certain level of leakage after impoundment through various causes, such as contraction joints and construction joints. However, due to the characteristics of concrete structures that shrink and expand according to temperature, concrete dams have vertical joints and drains to allow penetration. PVC waterproof shows excellent effects in completion of the dam, which however increases the possibility of interfacial failure due to different thermal expansion. Other causes of penetration may include problems with quality control during installation, generation of cracks due to heat of hydration of concrete, waterproofing methods, etc. In the case of Bohyunsan Dam in Yeongcheon, North Gyeongsang Province, the amount of drainage in the gallery was checked and underwater, and it was confirmed that there are many penetrations from drainage holes connected to vertical joints, and that some of the PVC waterproofs are not fully operated. As a new method to prevent penetration through vertical joints, D.S.I.M. (Dam Sealing Innovation Method) developed by World E&C was applied to Bohyunsan Dam and checked the amount of drainage in the gallery. As a result of first testing three most leaking vertical joints, the drain in the gallery was reduced by 87% on the average and then applied to the remaining 13 locations, which showed a 83% reduction effect based on the total drain in the gallery. Summing up these results, it was found that D.S.I.M. preventing water leakage from the upstream face is a valid construction method to reduce the water see-through and penetration quantity seen in downstream faces of concrete dams. If D.S.I.M. is applied to other concrete dams at domestic and abroad, it is expected that it will be very effective to prevent water leakage through vertical joints that are visible from downstream faces.

Given the interdependence of a marital couple, this study examined the effects of both cultural challenge and economic hardship on intention to divorce among the multicultural couple using the actor-partner interdependence model(APIM), and explored dyadic patterns of actor and partner effects. 415 couples(n=830) participated in this self-administered questionnaire study. Results of path analyses based on APIMs revealed that for Korean husbands perceived cultural challenge contributed positively to divorce intention of the couple showing both actor and partner effects, whereas for immigrant wives such perception showed only an actor effect. In contrast, perceived economic hardship among the husbands had little effect on divorce intention of both husbands and wives, whereas such perception by wives had both actor and partner effects on divorce intention. Results of dyadic pattern analyses performed by Bootstrap indicated the actor-only pattern and the couple pattern of perceived cultural challenge on divorce intention of husbands and wives respectively. In case of perceived economic hardship comparison of the effect size suggested the partner-only pattern and the actor-only pattern for divorce intention of husbands and wives respectively. These findings implied that in order to promote conjugal harmony and to prevent the multicultural family from being dissolved, Korean husbands need to develop greater cultural competence so as to tolerate cultural differences between the couple, whereas immigrant wives and their families need to develop greater economic competence so as to foster a hope for economic reliance.

Orthotropic steel decks are manufactured by welding thin plates therefore it is inevitable that there are abundant works of welding process. On connection of transverse rib web, crossing point of longitudinal rib, transverse rib and deck plate and cut-out parts of transverse rib are the significant position of stress concentration phenomenon because of out of plane and oil-caning deformation caused by longitudinal rib distortion with shear force and distortion. In order to reduce the stress concentration phenomenon and improving fatigue performance at the crosing point and cut-out, structural analysis was performed considering the existence of scalop at conection and diaphragm which have same plane with transverse rib placed inside of longitudinal rib. Result o f the analysis show that there are the largest efect of stres concentration reduction when diaphragms are installed without scallop at connection, therefore these detail can improve the fatigue performance of orthotropic steel decks.
