본 연구는 중학생들의 스포츠여가활동 참가에 따른 자녀와 부모의 의사소통과 학교생활적응의 관계를 분석한 것으로 토요 스포츠교실과 스포츠클럽을 다니는 중학생 200명을 연구대상으로 하였으며, 그 중 미흡한 자료 1부를 제외한 199부를 최종 자료로 사용하였다. SPSS 18.0을 이용하여 상관관계 및 다중회귀분석을 실시하였으며, 분석결과는 다음과 같다. 첫째, 자녀와 부모의 의사소통과 학생생활과의 관계를 분석한 결과 자녀와 부모의 의사소통 중 부모의사 기대 요인만이 통계적으로 유의한 영향을 미치는 것으로 나타났다. 둘째, 자녀와 부모의 의사소통과 교사관계와의 관계를 분석한 결과 자녀와 부모의 의사소통 중 부모의사 기대 요인만이 통계적으로 유의한 영향을 미치는 것으로 나타났다. 셋째, 자녀와 부모의 의사소통과 학교수업과의 관계를 분석한 결과 자녀와 부모의 의사소통의 자녀의사 표현과 부모의사 기대의 모든 요인에서 통계적으로 유의한 영향을 미치는 것으로 나타났다. The purpose of this study was to investigate how are related between communication relationship out of parents and students and adaptation to school life, so that notify that is important for juveniles to get involved into sports club and serve basic information for consulting for students to adapt school life. A survey was conducted to the students regarding the Saturday sports class and club, which is 200 students from middle school in C city using the sampling process of the party. Those 200 students only one has negative outcome-the rest of 199 students, I used our final analysis. And the study performed correction analysis and multiple regression using SPSS 18.0 program. The analysis results are as follows. Firstly, only the way of understanding for parents during communication between parents and students has a statistically significant differences in students` adaptation to school life. Secondly, only the way of understanding for parents during communication between parents and students has a statistically significant differences in relationship with teachers. Lastly, all elements of communication between parents and students has a statistically significant differences in school classes.

Low temperature δ-precipitation phenomenon below 2-step aging (718℃, 8 hr + 621℃, 8 hr) temperature of cold drawn Inconel 718 alloy wire was investigated. The investigation was carried out on wires with a cold drawn ratio of 0, 20, 50 and 70% using OM, SEM, XRD, TEM, and DSC. In microstructures of 50 and 70% drawn wire, many precipitates were found along the grain boundaries and the twin boundaries in deformation band. From the results of the XRD and TEM analysis, the precipitates were identified as platelike δ-phase. From the results of the DSC analysis, it was also found that a temperature of δ-precipitation decreases with an increase of the cold drawn ratio. We concluded that cold drawing of inconel 718 wire promotes the δ-precipitation, and under the condition of a high drawing ratio, the δ-phase could be precipitated at a temperature below the aging temperature (718℃).

전기자동차의 효율을 증대하기 위하여 많은 방법이 시도되었다. 시도한 중요관심사 중 하나가 난방시스템의 효율 증대이다. 그럼에도 불구하고 많은 효과를 보여주지 못하였다. 일반적으로 기존 차량에서의 난방시스템은 크게 중요하지 않았다. 차량의 엔진에서의 발열을 이용하였기 때문이다. 본 연구에서는 일반적인 PTC 시스템을 제어 방법을 지능제어 방법을 통하여 높은 에너지 효율을 얻었다. In order to improve efficient quality of EV, lot of methods has been tried. One of the main concerns in attempting is to increase the Heating system. Nevertheless not much improvement has been achieved. Generally the heating system in vehicle is not important. Because of vehicle heating system is used to engine temp. Remarkable energy efficient of development system from conventional PTC is demonstrated both in simulation and experiment as well.

새로운 감귤 품종 ‘탐도3호’는 2004년 국립원예특작과학원 감귤연구소에서 ‘청견’(Citrus unshiu × C. sinensis)을 교배모본(종자친)으로 하고 ‘Sunburst’(Citrus reticulate)를 교배부본(화분친)으로 교배하여 얻어진 교잡품종이다. 탐도3호는 2010년에 첫 착과가 되었으며 2012년까지 포장 평가를 실시하였다. 탐도3호의 수세는 강하며 풍산성이다. 열매는 평균적으로 230g이며, 과실의 모양은 작은 봉을 가진 납작한 편구형이다. 착색은 10월 중순부터 시작되어 2월 초에 완전히 착색되며 그 색은 짙은 오렌지색이다. 플라스틱 하우스 재배 시 성숙기는 2월 중순이다. 과실의 당도와 산도는 각 각 14.0°와 1%이다. 과피의 두께는 평균 2.5mm로 온주밀감보다 얇아 과피 벗김이 쉽다. 이 품종은 자가불화합성과 단위결과성이 있어 단독 재배 시 종자가 발생되지 않으나 다른 종의 꽃가루가 수정되면 종자를 형성한다. 탐도3호는 노지 재배 시 과실이 냉해를 받기 때문에 플라스틱 하우스 재배가 요구된다. A new citrus cultivar ‘Tamdosamho’ is a hybrid obtained from a cross of ‘Kiyomi’ (Citrus unshiu×Citrus sinensis, the seed parent) and ‘Sunburst’ (Citrus reticulate, the pollen parent) at the Citrus Research Institute of the National Institute of Horticultural and Herbal Science in 2004. ‘Tamdosamho’ had the first fruit set in 2010 and field evaluation has been conducted until 2012. The tree of ‘Tamdosamho’ was vigorous and had a lot of fruit bearing. The average fruit weight was 230g and its shape was flatten-oblate with a little neck. The fruit peel color was dark orange, and peel coloration began in mid-October and fully developed in early December. The fruit matured in mid-February from cultivation under plastic film house. Total soluble solid and acidity of which was 14.0 °Brix and about 1 % respectively. The thickness of the rind was about 2.5 mm on average and was thinner than that of satsuma mandarin (Citrus unshiu), so removing the peel was easy. This cultivar had characteristic of self-incompatibility and parthenocarpy and didn’t bear seeds from monoculture but if it be fertilized by the pollen of other cultivars could be seedy. In the case of cultivation in the open field, the fruits could be damaged by cold temperature and then ‘Tamdosamho’ is recommended for cultivation under plastic film house.

박상인,김용만,서병희,이재현,Park, Sang-In,Kim, Yong-Man,Suh, Byung-Hee,Lee, Jae-Hyun 대한생식의학회 1988 Clinical and Experimental Reproductive Medicine Vol.15 No.2
Combined (intra and extrauterine) pregnancy refers to impregnations of two different ova at intrauterine and extrauterine sites simultaneously or within a short time interval each other. It is a rare clinical entity and freqently missed in early diagnosis in most instances. Its incidence rate is about 1 in 30,000 pregnancies and the incidence was rised in cases of using ovulation induced agents. The diagnostic rate is less than 10% at early process of the disease. We experienced a case of intrauterine and left tubal pregnancy as combined pregnaney in ovulation cycle which had been induced by clomiphene citrate and now present it with brief review of related leteratures.

The intention of this study is to analyze architect's sketches which embody the concept of ambience in contemporary architecture. The watercolor sketches of Steven Hall have achieved a simultaneously contingent ambience which the perspective drawings can't represent. As a conclusion, ambience in architecture is the most transcendental term for enjoying the architectural presence. The ambiential results are clearly achieved by the concept sketches.

Despite of safety issues related to radiological hazards, 31 countries around the world are operating more than 450 nuclear power plants (NPPs). To operate NPPs safely, safety regulations from radiation protection organizations were developed and adopted in many countries. However, many cases of radionuclide releases at foreign NPPs have been reported. Almost all commercial NPPs routinely release radioactive materials to the surrounding environments as liquid and gas phases under control. These releases are called 'planned releases' which are planned, regularly monitored, and well documented. Meanwhile, the releases focused in this review, called 'unplanned releases', are neither planned nor monitored by regulatory and/or protection organizations. NPPs are generally composed of various structures, systems and components (SSCs) for safety. Among them, the SSCs near reactors are closely related to safety of NPPs, and typically fabricated to comply with stringent requirements. However, some non-safety related SSCs such as underground pipes may be constructed only according to commercial standards, causing the leakage of radioactive fluids usually containing tritium ($^3H$). This paper discusses SSCs of NPPs and introduces several cases of unplanned releases at foreign NPPs. The current regulation on the environmental radiological surveillance and assessment around the NPPs in South Korea are also examined.
