A cystic parathyroid adenoma is rare. A case of primary hyperparathyroidism, with the cystic formation of a parathyroid adenoma and a severe bony lesion, is reported. A 52-year-old male was admitted due to pain in both hips and for evaluation of hypercalcemia. The plasma level of the intact parathyroid hormone (iPTH) was elevated to 1424 pg/mL. Ultrasonography and the computed tomography revealed a parathyroid cyst on the left thyroid lower pole. Parathyroid scintigraphy detected a parathyroid adenoma. A radiograph showed a subperiosteal bone resorption on the phalanges, and a brown tumor (osteitis fibrosa cystica) on the femur shaft was noted. A surgical excision of the parathyroid adenoma was performed. The PTH level in the cystic fluid was increased. A histological examination confirmed a cystic parathyroid adenoma. The PTH level was normalized after the operation (J Kor SOC Endocrinol 18:214-220, 2003).

This study analyzes the future landscape assesment of Suyoung-River and adjacent areas. Computer Simulation method is used for these purposes. It is expected that the high buildings and high density in Suyoung Information Site might cover the Jang-Mountain view. Therefore this study analyzes the expectations by the experiment of the change of the heights of buildings and the view-point so that Suyoung Information Site can secure the feelings of openness and can be harmonious with natural landscape and skyline. If the high dense buildings are going to be constructed, the optimum condition of development should be between 1.5 and 2.0 of evaluation indicator. The minimum indicator 1.5 would be appropriate as the standard of regulation. The results show that the buildings along the riverside road in the west need to be regulated under the height of 30m(about 10 stories) and the buildings along the Chungryul-Street in the east under the height of 90m(about 30 stories). 하천은 산과 구릉지 등과 함께 도시의 아름다운 경관을 형성하는 중요한 경관요소이다. 도시내 하천변에 나타나는 경관문제는 대부분 대규모 건축물에 의한 경관 훼손에서 비롯된다. 부산의 대부분 하천은 시가지를 통하여 바다로 유입되고 있으나 대부분 복개되었거나 주변지역의 고층건물 입지로 인해 하천 자체가 시민에게 주는 정 (正)의 경관적 요소는 점점 감소하고 있다. 본 연구의 대상지인 수영강은 현재 시가지내를 흐르고 있어 시민에게 주요한 openspace로 기능하고 있다. 주변지역은 지금까지 수영 비행장이라는 기능으로 연해 개발이 유보되어 오다 최근 수영정보단지의 개발계획 등으로 인해 개발압력을 강하게 받고 있다. 향후개발이 진행된다면 수영강변에서 조망할 수있는 주변 자연경관과 시가지 경관은 차폐될 뿐만 아니라, 그 자체의 규모가 크고 형태도 단조로와 위압적이고 획일적인 경관이 형성되게 될 것이다. 현재에도 수영강변의 구릉지에는 아파트 가 입지하여 조망을 차폐하고 있을 뿐 아니라 녹지를 잠식하고 있다. 이러한 현상은 향후 개발압력에 빌려 수영강변의 어느 지역 에서나 발생하는 공통적인 현상이 될 것이다. 이러한 조망차폐, 획일성, 위압감의 조성, 지형의 훼손 및 잠식 등으로 대표되는 수영강의 경관문제는 현행법상 건축심의 시 받는 경관심의로 해결하기에는 한계가 있다. 따라서 본 연구는 수영강과 연접지역, 그리고 배경녹지축인 주변산을 공간적 범위로 하여 첫째, 수영강 연접지역의 범위를 설정하고 연접지역을 몇 개의 경관구역으로 나누어 각 경관구역별 경관의 문제점과 특성을 살펴본다. 둘째, 경관분석을 위하여 Computer를 이용한 수영강변 주요 조망점 에서 사람의 눈에 보이는 대로 주변 경관을 연출해 낼 수 있는 가상의 경관 Simulation을 실시한다. 셋째,이를 바탕으로 수영강 연접지역의 건축물 고도규제 를 위한 기준설정과 고도규제 방안을 제안하는데 목적이 있다.

윤인식,정운관,김성영,염유선,심재학 조선대학교 에너지.자원신기술연구소 2003 에너지·자원신기술연구소 논문지 Vol.25 No.2

우리나라에서도 원자력발전이 상용화된지 이십여년을 넘어서면서 원자력발전을 하고 있는 다른 나라와 마찬가지로 사용후핵연료 관리가 국가적인 문제로 심각히 대두되고 있다. 중간저장 시설은 1997년부터 운영예정이었으나 현재 그의 부지가 아직 확보되지 못한 상태에서 그 운전개시 시점이 불확실하다. 그리고 중간저장 이후의 사용후핵연료 정기관리 전략이 아직 마련되어 있지 못한 실정이다. 그러므로 발전소에서 발생되는 사용후핵연료 양과 그에 따른 선원항 평가는 반드시 선행되어야 할 것이다. 이제 본 연구에서는 국내 사용후핵연료 형태중 17×17에 대해서 농축도와 연소도 그리고 냉각시간별로 선원항 평가를 하였다. 사용후핵연료 선원항 평가를 위해 미국 Nuclear Regulatory Commission(NRC)의 인·허가 코드인 SCALE 코드를 이용하였다. 선원항 평가는 SCALE 코드의 모듈을 이용하였다. 선원항 평가 결과 농축도와 3.5 w/o와 연소도 35 GWD/MTU 일때 Cooling Time 0.3년은 7.5651E+16, 1년 2.8954E+16, 3년 9.8242E+15, 5년 5.4000E+15, 10년 3.0945E+15으로 계산되었으며, Cooling Time이 0.3년일때와 10년일때의 Source Term이 크게 차이가 남을 알 수 있었다. 방사선량율은 10 ㎝부터 500 ㎝ 까지 거리에 따라 선량율에 대하여 10 ㎝ 4.8365E+03(㏉/hr)에서 500 ㎝ 7.8456E+01으로 감소함을 알 수 있었다. 현재 국내 사용후핵연료에 대한 선원항 평가가 이루어지지 않았으며, Data Base 구축이 기초단계 이므로 이러한 기초자료는 추후 저장조가 건설되면 사용후핵연료 안전성과 관련하여 사용할 수 있는 것이고 기초 Data Base구축하는데 이용할 수 있을 것이다 As nuclear power has been used in our country over 20 years, spent fuel management is raised seriously as one of the national`s problems, which lies in similar situation to other countries having nuclear power plants. An interim storage facility has been planned to operate in 1997, it is highly uncertain whether this facility will start to operate by the time because the site has not been decided yet. After the intermediate storage, the spent fuel periodical management strategy has not prepared yet. Therefore it has to be preceded that the spent fuel quantity which is happening at the power station and the following source term. Now the main have evaluated the source term according to enrichment, burn-up, and cooling time for 17×17 of spent fuel form. I used the SCALE code which were certified by Nuclear Regulatory Commission(NRC) for the source term calculations of Spent Fuel. The source term was calculated, which reflected the feature of target nuclear fuel using ORIGEN-S, a module of the SCALE Code, and the exposure dose rates were calculated by using the QADS modules, considering the geometry. When the enrichment in the evaluated result of source term is 3.5 w/o and the burn-up is 35 GWD/MTU, the cooling time 0.3year is 7.561E+16(photon/second), 1year 2.8954E+16, 3year 9.8242E+15, 5year 5.400E+15, 10year 3.0945E+15 and found that the big difference in Photon Spectrum of cooling time 0.3year and 10year. I have found that radiation dose rate is decreased in 10㎝ 4.8365E+03(㏉/hr) into 500 ㎝ 7.8456E+01 for dose rate according to distance from 10 ㎝ to 500 ㎝. It is not made the source term evaluation on the domestic spent fuel, and since the data base construction is basic level, some time later, if the storage place is constructed, in connection with the safety, these basic data can be used and we can construct these basic data base.

MC₃T₃-E₁골아세포군을 이용하여 IGF-Ⅰ과 Ⅱ를 투여하고 DNA합성과 골아세포기능을 측정하기 위해 PTH에 대한 C-AMP반응정도, alkaline phosphatase 활성도를 측정하여 다음과 같은 결과를 얻었다. 1) IGF-Ⅰ과 Ⅱ는 모두 DNA합성이 어느 농도까지는 증식효과를 나타내지만 그 이후에는 억제되는 양상을 보였다. 2) PTH에 대한 골아세포의 C-AMP반응으로 증가되었지만 IGF-Ⅰ과 Ⅱ의 투여시 농도변화에 따른 의미있는 변화는 없었다. 3) 본 실험의 조건에서 alkaline phosphatase 활성도는 증가되지 않았다. 이상의 결과로 MC₃T₃-E₁ 골아세포에 IGF-Ⅰ과 Ⅱ는 세포의 증식을 자극하여 PTH는 C-AMP생성을 촉진하는 효과가 있었다. The effect of insulin-like growth factor (IGF) Ⅰ and Ⅱ on cloned MC₃T₃-E₁ cells that had osteoblastic activity was examined by [³H] thymidine incorporation into DNA, cyclic AMP responsiveness to parathyroid hormone (PTH), and alkaline phosphatase activity. IGF Ⅰ and Ⅱ stimulated the growth and proliferation of osteoblastic cells at 20ng/㎖ and 50ng/㎖, respectively. We next examined the effect of IGF-Ⅰ and Ⅱ on the expression of osteoblastic activity. Adenylate cyclase response of PTH to IGF-Ⅰ and Ⅱ-treated cells showed maximal stimulation at 10 and 50㎚PTH, respectively, but IGF Ⅰ and Ⅱ induced limited activity of osteoblastic function. In conclusion, IGF-Ⅰ and Ⅱ were potent stimulators to the growth of osteoblastic cells but did not have an immediate effect on expression of osteoblastic function in this experiment.

This study had an object to inspect the effect of meta cognition level come up to on learner’s learning attainment in social studies class. The general idea of Meta cognition for Knowing about one’s comprehension while one’s studying. Then examined this for better classwork. Meta cognition includes all of these processes. It’s based on constructivism. And it is a notion that is helping an active study. And comprehension level is a common goal as education reform plan. Because that would make an excellent addition which makes for the competition power security in the future. Therefore, if you analyze a Meta cognition level and a comprehension level, you can develop your abilities (self control ability in complicated situation, recognize by self control develop study efficiency). All of these processes show these are important things in social education text books. In this study, investigated thoroughly about the Meta cognition and social affairs division looked out a recent result before took this survey. It was surveyed about Meta cognition level in natural lesson situation. Then, we proved relation between their comprehensions (which was taken by each of their mid-term tests results) and their Meta cognitions through a statistical program, SPSS win 12.0. I choose 100 students in each school, then randomly selected except people who were not fitness of the test. We hypothesized dependent variable is a record of social studies, independent variable is Meta-cognition level, and variable of control is their characteristics This survey was taken from June, 2006 to July, 2006. First, the researcher explained the survey’s purpose and tenors to the schools, then got their agreements to do the Meta cognition test. We used mid-term test’s result in social studies education.

Background: In most cases of a foreign body in the esophagus, an ENT specialist is consulted, which may be time consuming if not evaluated in a timely fashion. The patients are admitted to the hospital and sent to the operating room, where they are placed under anesthesia and the object is removed by using an esophagoscope. Methods: A prospective randomized trial was conducted during the period from January 1998 to June 2000. All patients presenting to emergency department with blunt objects in the esophagus were included. In one group, with fluoroscopic guidance, a Foley catheter was placed to remove the blunt foreign bodies. And in the other group, we removed them by using the esophagoscpe. We used the t-test for statistical analysis in this study. Results: Total number of patients enrolled in this study was 38.22 patients were enrolled in the Foley Catheter removal group, and the remaining 16 were enrolled in the esophagoscope removal group. The success rate for the Foley catheter was 21/22(95.5%), and that for the esophagoscope was 15/16(93.8%). The average time of removal for the Foley catheter group was 0.70± 0.28 hours while that for the esophagoscope group was 5.96 ± 2.22 hours. One side effect, nonfatal hypoxia, was noted in the Foley catheter removal group. The average cost for the Foley catheter group were 78,800 won(approximately 600 US dollars) while that for the esophagoscope group took 722,800 won(approximately 600 US dollars). Conclusion: In our study, we found that the success rate for removing blunt foreign bodies from the esophagus by using a simple Foley catheter was high, also the Foley catheter was a time saving and cost effective procedure with an excellent safety profile.
