Adrenal cortical tumors are rare in adults and children. Most are malignant and functional. The principal clinical features are virilization, Cushing's syndrome, hyperaldosteronism and feminization. Recently, we treated a case of virilizing adrenal cortical tumor in a 26 month-old boy. The diagnosis was made by hormone assay, abdominal CT and tissue pathology. Right adrenalectomy was successful performed. Pathologic examination revealed an adrenal cortical adenoma with vascular invasion.

Thermal infrared cameras have been conducted actively in various application areas, such as military, medical service, industries and cars. Because of their characteristic of sensing the radiant heat emitted from subjects in the range of long-wavelength($3{\sim}5{\mu}m$ or $8{\sim}12{\mu}m$), and of materializing a vision system, when general optics materials are used, they don't react to the light in the range of long-wavelength, and can't display their optic functions. Therefore, the materials with the feature of higher refractive index, reacting to the range of long-wavelength, are to be used. The kinds of materials with the characteristic of higher refractive index are limited, and their features are close to those of metals. Because of these metallic features, the existing producing method of optical systems were direct manufacturing method using grinding method or CAD/CAM, which put limit on productivity and made it difficult to properly cope with the increasing demand of markets. GASIR, a material, which can be molded easily, was selected among infrared ray optics materials in this study, and the optical system was designed with two Aspheric lenses. Because the lenses are molded in the environment of high temperature and high pressure, they require a special metallic pattern. The metallic pattern was produced with materials with ultra hardness that can stand high temperature and high pressure. As for the lens mold, GMP(Glass Molding Press) of the linear transfer method was used in order to improve the productivity of optical systems for thermal infrared cameras, which was the goal of this paper.

모멘트 저항골조는 내진성능이 매우 우수한 것으로 알려져 왔으며 많은 건축물의 설계에 이용되며 시공되어지고 있으나 노스리지 지진과 고베 지진시 충분한 내진성능을 발휘하지 못하고 접합부에서 균열 또는 취성파괴가 발생하였다. 양지진 이후 접합부의 내진성능을 향상시키고자 접합부 상세에 대한 연구가 활발히 진행되고 있으며, 우리나라에서도 지진에 대한 사회적 관심과 일본에서 발생한 지진이 한반도에 영향을 주는 상황에서, 이에 대한 사회전반의 관심과 우려가 제기되고 있다. 본 논문에서는 H형 보 웨브의 고장력볼트 전단접합과 H형 플랜지의 리브보강 유무를 변수로 한 실대형 실험체를 가지고 실험을 실시하였다. 실험을 통해 보 웨브의 2면 전단접합을 통해 고장력 볼트수 감소와 시공성 향상을 기대하며, 리브플레이트 보강을 통해 내진성능을 향상시키고자 한다. 또한 논 스켈럽을 통해 응력집중에 의한 취성파괴를 방지하고자 한다. The moment resisting frame has been well-known as it had very excellent seismic performance, and it has been widely used and constructed in the design of a lot of buildings. However, the moment resisting frame system did not exert the seismic performance during the earthquake in Northridge and Kobe sufficiently, and it produced the crack or brittle fracture on the joint. this study was to ]m tests with the full-scale test subject as parameters of existence of H-beam web high tensile bolt shearing joint and reinforcement of H-flange rib. This researcher was to anticipate the decrease of number of high tensile bolts and the improvement of workability through the double shear joint by the experiment, and improve the seismic performance through the reinforcement of rib plate. In addition, this study was to prevent the brittle fracture by the stress concentration through the non scallop.

미국과학재단(NSF) 지구과학위원회(GEO)의 지질과학사업단(EAR)은 미국의 국가 전략적 필요성에 직접적으로 적용될 수 있는 지구시스템에 관한 기반 기초 지식을 얻기 위한 기초연구를 지원하고 있다. 2011년도에 국가과학위원회(NAS)의 지구과학 신규 연구유망주제위원회는 향후 10년 동안에 급격한 발전에의 대응을 위한 지질과학분야 기초 과학연구의 특정주제를 도출하였다. 다학제적 접근에 의해 정리한 지질과학사업단의 심부지질과정과 지표지질과정분야 유망주제들은 (1)초기 지구연구, (2)열-화학적 내부 동력학 및 휘발성분 분포, (3)단층작용과 변형과정, (4)기후, 지표변화, 판구조, 심부지구과정의 상호작용, (5)생명, 환경 및 기후의 공동 진화, (6)자연과 인위적 변화에 동조화된 수리지형-생태계 반응, (7)육상환경과 글로벌 변화영향에서 생화학 및 물순환 등이다. 우리나라에서도 임계구역 연구(Critical Zone studies) 등의 미래분야의 연구가 활발하게 추진되고 있다. 이러한 미래의 거대연구를 활발하게 추진하기 위해서는 추가 연구지원 정책이 필요하다. The essential role of the Division of Earth Sciences(EAR) in the Directorate of Geoscience(GEO) of National Science Foundation of America(NSF) is to support basic research aimed at acquiring fundamental knowledge of the Earth system that can be directly applied to the United States' strategic needs. The 2011 Committee on New Research Opportunities in the Earth Sciences(NROES) of the National Academy of Sciences(NAS) identified specific areas of the basic earth science research scope of the EAR that were poised for rapid progress during the next decade. Quantified by interdisciplinary approaches, the Committee highlighted the following topics relating to the EAR Deep Earth Processes and Surface Earth Processes sections: (1) the early Earth; (2) thermochemical internal dynamics and volatile distribution; (3) faulting and deformation processes; (4) interactions among climate, the Earth surface processes, tectonics, and deep Earth processes; (5) co-evolution of life, environment, and climate; (6) coupled hydrogeomorphic-ecosystem response to natural and anthropogenic change; and (7) interactions of biogeochemical and water cycles in terrestrial environments. We also promote future research challenges such as the critical zone studies. In order to promote more active such a huge future research challenges, additional research support policies are needed.

본 연구는 비균열 무근콘크리트에 매입된 앵커의 앵커간격 및 하중방향에 따른 전단내력 평가를 목적으로 하고 있다. 이를 위하여 앵커의 전단내력 설계식을 비교 평가하였으며, 실험값과 기존의 설계식의 예측값을 비교 분석하였다. 그 결과, 앵커간격 및 하중방향에 따른 CCD 방법 및 EOTA 설계식은 합리적인 설계방법임을 알 수 있었다. This study concerns the prediction of shear capacity, as governed by concrete breakout failure of the anchors under load applied angle and an group anchors at an edge and installed in uncracked, unreinforced concrete. For this purpose, the methods to evaluate the shear capacity of the anchors in concrete are summarized and the experimental data are compared with capacities by the two present methods: the method of ACI 349-90 and concrete capacity design (CCD) method.

After Yeungnam University's College of Medicine was established in 1979, the curriculum for a preclinical medical education course was developed and implemented. Several modifications have since been made to the curriculum which was driven by changes in national policies and in the medical education environment. In recent years, it has become necessary to complement the weaknesses or shortcomings in the curriculum that were discovered during the basic medical education assessment process of the medical college. Since 2009, Yeungnam University has run two medical courses: a 6-year college of medicine course and a 4-year medical school course. However, as a result of changes in national policy, Yeungnam University decided to offer only the 6-year college of medicine course with an entirely new curriculum which will be implemented in 2017. The new curriculum for the preclinical medical education course consists of 36 credits of cultural essentials courses, 44 credits of major required courses, and 2 credits of major elective courses. The curriculum development requires the support of the university and/or college, the ensured independence of the curriculum development organization, and the cooperation and attention of fellow professors. Continuous efforts are needed to check, evaluate, and improve the curriculum.
