This study investigated the background of the intellectual ability that consists of family environment, intellectual priority, career aims, intellectual extracurricular activities of the students who were selected for the Science Gifted Education Center. We performed a survey and analysis of the students at the Science Gifted Education Center in order to explore their learning attitudes and intellectual ability, as well as the elements that represent their attitudes. As a result of the study, I found that the students in the Science Gifted Education Center generally had good economic and family backgrounds that showed no significant hardship in supporting the students. The families were also highly educated intellectually. In case the talented students in Science desired to be pure scientists, they liked the Science subjects and enjoyed reading science books. It was mostly the male students that took part. As for the attitude toward intellectual ability, they expected to improve their abilities as they gained knowledge and increased their intelligence through learning, although they didn't confide with us on their intelligence quotients. There were four factors for these attitudes. They include the high expectation of them by others; confidence and ease of mind regarding the assignment; the expectation for improvement in intelligence and ability through learning; and, confidence in intelligence and positive attitude in the participation situatio 본 연구는 과학영재교육센터에 선발된 학생들의 가정 환경, 지적 선호, 장래 희망, 지적 과외 활동 등으로 구성된 지적 능력의 배경을 조사하고, 지적능력에 대한 수용 태도와 그 태도를 나타내는 요인을 탐색하기 위하여 과학영재 학생들을 대상으로 설문조사와 분석을 하였다. 본 연구 결과 초등학교 과학영재 학생의 가정은 대체로 경제적으로 교육을 시키는데 어려움이 없었으며, 지적으로는 높은 수준의 환경을 갖고 있었다. 과학영재 학생이 순수과학자가 되기를 희망하는 경우 이들은 과학과목을 좋아하고, 과학 책을 즐겨 읽으며 남학생일 경우가 많았다. 지적 능력에 대한 과학영재 학생들의 수용 태도는 대체로 지능에 대한 자신감은 크지 않았지만 학습을 통하여 지식이 많아지면 지능과 능력이 향상될 것으로 생각하고 있었다. 이러한 태도의 요인으로 자기의 지능에 대한 다른 사람의 높은 기대, 과제 해결에 대한 자신감과 여유, 학습에 의해 지능과 능력이 향상될 것으로 기대, 지능에 대한 자신감과 상황 참여에의 적극성 등 4가지 요인을 정의하였다.

박상우,황성남,박승원,김영백,최덕영,Park, Sang Woo,Hwang, Sung Nam,Park, Seung Won,Kim, Young Baeg,Choi, Duck Young 대한신경외과학회 2000 Journal of Korean neurosurgical society Vol.29 No.7

A sixty-three year old woman presented with sudden onset of dystonic twitching of the extremities and repeatedly downgrading of consciousness in the midnight. She had no history of medical illness in the past but had been suffered from fatigue recently before the onset of the attack. At admission she was neurologically free including neuro-ophthalmologic examination. MRI showed a high signal T1WI mass in the sella protruding into the suprasellar cistern. Hormonal study revealed low value of T3, T4, LH and FSH. Under the impression of pituitary apoplexy she underwent operation via transcranial route. When the protruding diaphragma sellae was opened, milkish pus spilled out. The thick capsule was biopsied and pus was sent for the study. The results of Gram staining and culture were both negative but pathologic report of the specimen was high infiltration of lymphocytes with few polymorphs.

메타데이터 교환표준(XMI)을 이용한 분산 이종 GIS 데이터베이스 검색

박상우,유상봉,Park, Sang-Woo,Yoo, Sang-Bong 한국공간정보학회 2000 개방형지리정보시스템학회 논문지 = Journal of the Korea Open Geogr Vol.2 No.1

As the networks proliferate all over the world and the application of the geographical information increase recently, the importance of effective access and exchange of GIS data is recognized. However, existing GIS data are generated by many different organizations without proper standard methodologies and data exchange facilities such as clearing houses are being operated on different DBMS with their own schemata. It makes difficult for users to access and utilize the GIS data even the data are open to public. In this research, we provide the users a search system that interfaces heterogeneous repository systems. In order to interact heterogeneous DBMS we utilize the metadata interchange standard (XMI) from OMG. 최근 네트웍의 보급과 지리정보의 활용이 증가하면서 효과적인 지리정보의 검색과 접근에 대한 중요성이 강조되고 있다. 하지만 기존의 GIS 데이터는 지리적으로 분리된 여러 부서나 조직에서 생성 및 관리되고 있으며, 공간 정보 유통을 위한 클리어링하우스 등이 서로 다른 DBMS 상에서 독자적인 스키마를 가지고 개발되어 있다. 이러한 이질적인 구조와 구현 환경으로 인해 일반 사용자들이 서로 다른 GIS 데이터베이스를 접근하여 검색하는데 많은 어려움이 따르고 있다. 본 연구에서는 OMG의 메타데이터 교환 표준인 XMI로 표현된 이질적인 GIS 데이터베이스의 메타데이터를 통하여 사용자에게 각 데이터베이스의 구현 환경과 스키마에 독립적인 공간 데이터를 검색 기능을 제공하는 검색 시스템을 구현하였다.

Purpose: To compare the surgical outcomes of functional equator-considering and Parks’ methods in infantile esotropia and partially accommodative esotropia. Methods: The medical records of 96 patients with infantile esotropia and partially accommodative esotropia who underwent bilateral medial rectus muscle recession by functional equator-considering and Parks’ methods were reviewed retrospectively. The surgery success rate at 1 month, 3 months, 6 months and 12 months was compared by the deviation angle measurement. Results: Overall success rates were not statistically different between the 2 groups. Additionally, there were no differences in surgical success rate of functional equator-considering and Parks’ methods in infantile esotropia and partially accommodative esotropia. When the patients were divided into 2 groups based on 40 PD, no significant difference in success rate between the 2 groups was observed. When patients were divided into 2 groups based on 22 mm of axial length, there was no statistical difference observed. Postoperative overcorrection was 2 (4%) in the functional equator group and 3 (6.5%) in Parks’ method group and postoperative undercorrection was 9 (18%, 19.6%) in each group. The incidence of undercorrection in the Parks’ method group was significantly higher in the greater than 22 mm axial length group (7, 35.0%) than in the less than 22 mm group (2, 7.7%) (p = 0.029). Conclusions: There was no statistically significant difference in surgical success rate between the functional equator and Parks’ methods in infantile esotropia and partially accommodative esotropia.

Purpose: To evaluate the effect of dorzolamide-timolol and latanoprost on redox cycle of superoxide dismutase (SOD) and ascorbic acid in the aqueous humor of the rabbit. Methods: Group 1 (20 eyes of 10 rabbits) was instilled with dorzolamide-timolol in the right eye and Group 2 (20 eyes of 10 rabbits) was instilled with latanoprost in the same manner. Four weeks after instillation, SOD activity and ascorbic acid concentration were analyzed. Results: In Group 1, SOD activity and ascorbic acid concentration of the right eye and left eye were 15.7% and 19.3% (p=0.27), 2.7 pM and 2.6 pM (p=0.47), respectively. In Group 2, SOD activity and ascorbic acid concentration of the right and left eye were 22.3% and 27.6% (p=0.14), 2.3 pM and 2.1 pM (p=0.89), respectively. Conclusions: There was no significant difference of SOD activity and ascorbic acid concentration between both eyes in Group 1 and 2.

에너지파일은 기존의 수직밀폐형 지중열교환기를 경제적으로 대체할 수 있는 새로운 형태의 지중열교환기이다. 즉, 에너지파일은 건물의 기초 구조물과 지중열교환기의 역할을 동시에 수행하는 에너지 구조체로서, 말뚝 기초 내부에 열교환 파이프를 삽입하고 파이프를 통해 유체를 순환시켜 지반과의 열교환을 유도한다. 본 연구에서는 병렬 U형(5쌍, 8쌍, 10쌍)의 열교환 파이프를 대구경 현장타설 에너지파일에 삽입하여, 3본의 에너지파일을 실규모로 시공하였다. 또한 현장 열응답 시험(In-situ thermal response tests, TRTs)을 수행하고 시공된 현장타설 에너지파일과의 열교환 효율을 비교하기 위하여 30m 깊이의 수직밀폐형 지중열교환기를 별도로 시공하였다. 병렬 U형 현장타설 에너지파일에 대해서는 냉난방 부하를 인공적으로 주입하는 열교환 성능 평가시험을 수행하여 열교환 성능(heat exchange rate)을 평가하였다. 마지막으로 현장타설 에너지파일의 적용성 평가를 위해 산정된 상대 열교환 효율(relative heat exchange efficiency) 및 열교환 성능을 선행 연구 결과와 비교하였으며, 본 연구에서 시공된 현장타설 에너지파일은 안정적이고 효율적인 열성능을 보이는 것으로 나타났다. An energy pile is one of the novel ground heat exchangers (GHEX's) that is a economical alternative to the conventional closed-loop vertical GHEX. The combined system of both a structural foundation and a GHEX contains a heat exchange pipe inside the pile foundation and allows a working fluid circulating through the pipe, inducing heat exchange with the ground formation. In this paper, a group of energy piles equipped with parallel U-type (5, 8 and 10 pairs) heat exchange pipes was constructed in a test-bed by fabricating in large-diameter cast-in-place concrete piles. In addition, a closed-loop vertical GHEX with 30m depth was constructed nearby to conduct in-situ thermal response tests (TRTs) and to compare with the thermal performance of the cast-in-place energy piles. A series of thermal performance tests was carried out with application of an artificial cooling and heating load to evaluate the heat exchange rate of energy piles. The applicability of cast-in-place energy piles was evaluated by comparing the relative heat exchange efficiency and heat exchange rate with preceding studies. Finally, it is concluded that the cast-in-place energy piles constructed in the test-bed demonstrate effective and stable thermal performance compared with the other types of GHEX.
