This study aimed to identify elementary school teachers' perceptions of various aspects of physical environments of a classroom. For the purpose, a survey questionnaire was administered to 982 classroom teachers(female 82.2%) working at 67 elementary schools(Seoul 55%) located in Seoul and Busan. According to the analyses of the survey data, 50.8% of the respondent teachers suggested 20-25 as an optimum class size. Also, 57% of the teachers were positive about the current size of a classroom($67.5m^2$), but evaluations of a classroom size were divided between the teachers who had more and less than 30 students in class. Furthermore, three factors, labelled as 'uniqueness', 'residential stability' and 'visually pleasing', were extracted from a factor analysis of the Semantic Differential Scale consisting of 24 adjectives evaluating a classroom environment. Teachers from Busan tended to rate higher in the uniqueness domain while female teachers scored higher in the domain of residential stability, respectively, compared to their counterparts. Overall, the teachers perceived their classrooms having no particular characteristics, but rated highly in terms of stability. In addition, it was found out that the teachers' requests for the improvement of a classroom environment were not so much as the increased size of a classroom as a reduced class size as well as educational facilities that are corresponding to a variety of instructional methods. In summary, this study confirmed that elementary school teachers' perceptions of a classroom environment varied according to such factors as sex, teaching career, grade of their concerned class, and class size.

Research has begun to change the waterproofing design of domestic underground structure parts from the current negative-side waterproof design to the positive-side waterproof design. For this, active review from the design stage to prevent the ingress of external ground water into the waterproofing measures of the underground of apartment buildings is needed. Therefore, in this study, proper waterproofing method for the major leaks identified in the previous studies and a waterproofing method for the waterproof design of the underground floor and the outer wall is proposed. It is hoped that a follow-up study, such as a review of field applicability, for the proposed methods will provide an alternative to secure leakage stability in waterproof design.

The Dangri Crushed Stone Quarry is located in Dangridong, Busan City, and around the estuary of the Nagdong River. The quarry is considered to be a very promised one in the urban area from the standpoints of the assessment of the aggregate rank, the environmental impacts and the transportation distance. The crushed stones for aggregate of the quarry marks the higher rank in the gravity, the absorption ratio, the abrasion ratio, and the stability in comparison with the JISA 5005. The basement vibrations of the residential section in the vicinity of the quarry, which are arised by the millisecond blasting at the quarry site using the gelatin dynamites less than 39kg in weight, are measured to assess the vibration nuisance. The values of acceleration and the magnitudes are less than eight gals and O on the Richter scale respectively, the vibration nuisance thus can be ignored in such scales of the experiments. The traffic vibrations of the residential section are slightly susceptible. In the experiments, the traffic vibrations appears to be sensibler to the basement than the explosion vibration. The explosion noises in the experiments are not checked not only on the RION Sound Level Meter but also to our ears. The values of traffic noises also are in the safety values of the noise nuisance. The crush dust suspends in the air toward the upper valley in the opposite side of the residential area because of the influences of the sea breeze and the valley wind in the daytime, and the monsoon and the topographic disposition. the dust nuisance thus would not be remained in problem. The quarry is operated in the daytime only. The traffic dust in the residential area will be reduced by the faultless pavement and the careful driving. The elaborate survey on the ridges and peaks surrounded the quarry is recommended to prevent in advance the accidents of the rock slide. Moreover, it is required to make an advisory committee to develop the industry and to save the techniques. The most important matter is the accomodation between the attitude of the enterprising man for the social responsibility to the public nuisance and the cooperative spirit of the inhabitants for the industry.

본 연구는 한국노동패널의 11차 연도부터 19차 연도자료를 이용하여 주거이동에 영향을 미치는 요인을 분석하였다. 또한, 소득계층을 구분한 후 저소득계층의 계층변동이 없는 가구와 변동이 있는 가구의 주거이동 영향요인을 전체가구와의 비교를 통해 이들의 주거이동에 영향을 미치는 요인을 살펴보았다. 분석결과, 저소득층은 주거이동확률이 낮은 것으로 확인되었으며, 전체가구와 데이터를 분할하여 살펴본 가구특성에서 공통적으로 유의한 변수로 연령과 점유형태로 나타났다. 특히 소득계층 변동이 없는 가구에서 연령과 주거비용, 전월세의 임차가구만이 유의함을 보임으로써 이들의 주거비부담 완화를 위한 정부의 노력이 필요함을 시사하고 있다. 또한 소득계층의 변동이 있는 가구에서는 총소득과 상용직 종사자수가 전체가구와 마찬가지로 유의한 변수로 나타나 저소득계층의 고용 안정성을 높일 필요가 있음을 말해주고 있다. 본 연구의 결과를 볼 때 저소득계층 내에서도 불균형이 심화되어 있다고 볼 수 있으므로, 저소득층의 소득향상과 주거안정을 위해 지속적인 실태조사를 통한 주택정책을 펴야할 것이다.

우리나라 주택임대차보호법은 민법의 특별법으로 국민의 주거생활의 안정을 보장하기 위하여 1981년 3월 5일 법률 제3379호로 제정된 이후 지금까지 15차례의 개정을 통하여 유래를 찾아볼 수 없을 정도로 무주택영세민의 권익보호에 앞장서 왔다. 그러나 급히 서둘러 만든 입법이어서 법조문 제3조 제1항 "주택임차인이 임차주택을 인도받고 주민등록까지 마치면 그 다음날부터 그 주택의 소유자가 제3자로 변경되더라도 그 제3자에 대하여 임차권을 가지고서 대항할 수 있다"는 대항력 부분에 있어서 시행 당초부터 무주택영세민의 보호취지에 역행한다는 문제점이 노출되었던 것이 사실이다. 또한 이 조항이 오히려 사회적 약자들의 주거문제를 더욱 심각하게 만들었고, 국가는 이에 대한 대책이나 보호방법을 현실에 맞추어 개정하지 못한 이유로 지금까지 다양한 문제들이 제기되어 주택임대차와 관련된 분쟁들이 많이 발생되고 있다. 따라서 본 논문에서는 임차인의 주거안정을 위하여 주택임대차보호법의 대항력에 대한 문제점을 도출하고, 외국입법례를 통하여 주택임차인들에게 현실적으로 주거안정에 기여할 수 있는 개선방안을 제시하고자 한다.

Much advancement has been made in wind power due to modern technological developments. The wind energy technology is the world's fastest-growing energy option. More power can be generated from wind energy by the use of new design and techniques of wind energy machines. The geographical areas with suitable wind speed are more favorable and preferred for wind power deployment over other sources of energy generation. Today's wind turbines are mainly the horizontal axis wind turbines (HAWTs) and vertical axis wind turbines (VAWTs). HAWTs are commercially available in various sizes starting from a few kilowatts to multi-megawatts and are suitable for almost all applications, including both onshore and offshore deployment. On the other hand, VAWTs finds their places in small and residential wind applications. The objective of the present work is to review the technological development, available sizes, efficiencies, structural types, and structural stability of VAWTs. Structural stability and efficiencies of the VAWTS are found to be dependent on the structural shape and size.
