연구목적: 입학시험에서 짧은 시간동안의 면접을 통하여 학생을 선발하는 것이 대부분의 현실이며 이 러한 면접형태에서는 평가의 신뢰도를 확보하기 어렵다는 것이 큰 단점이다. 따라서 단시간의 면접이 지만 면접에서 목표로 하는 지적 역량에 따라서 문제를 객관구조화하여 개발하고 이렇게 개발된 문제 유형에 따라 인지적 요소를 측정하는 것이 타당성이 있는지 그 가능성을 모색하기 위해 이 연구를 시 행하였다. 대상 및 방법: 2006년부터 2008년까지 3년동안 충북대학교 의학전문대학원 입학전형에서 시행한 면접시험문제 중에서 대조적인 두 가지 문제유형(각각 2문제)의 채점결과를 1학년(기초의학과정)과 2 학년(임상의학과정)의 교육과목들의 학점들과 연관성이 있는지를 살펴보았다. 결과: 면접문제 유형 중에서 생물학에 대한 사전지식을 측정한 결과는 학업 성취도와 전혀 상관관계 를 나타내지 않았으나, 사고력(도표 해석 능력)에 관한 평가 결과는 2008년 2학년 2학기에 평점에서 유의한 상관관계를 나타내었다. 기초의학과목의 경우, 신경해부학(2006년), 약작용의 원리(2006년), 의료와 사회I(2006년), 비뇨생식계통의 이해(2006년)에서 유의한 상관관계를 나타내었다. 임상의학과 목에서는 내분비대사학(2008년), 알레르기 감염 면역(2008년), 신장요로의학(2008년), 모성태아의학 및 신생아학(2008년), 여성의학(2008년), 신경의학(2008년)에서 유의한 상관관계를 나타내었다. 결론: 입학면접에서 측정한 지적 역량과 학업성취도는 연관관계가 어느 정도 있는 것으로 나타났다. 즉, 생물학에 대한 사전지식에 대한 평가 결과보다 사고력에 대한 평가 결과가 충북대학교 의학전문대 학원의 학업성취도와 연관성이 높은 경향을 나타내었다.

수입뒤영벌을 대체할 수 있는 값싼 국산뒤영벌을 개발하기 위한 기초자료로서 1995년부터 1997년까지 3월에서 10월까지 중부지방 및 남부지방을 중심으로 뒤영벌의 분포조사 및 밀원식물을 조사하여 다음과 같은 결과를 얻었다. 1995년부터 1997년까지 채집한 국내종 뒤영벌의 종수는 9종으로 뒤영벌속 7종; 좀뒤영벌, 호박벌, 삽포로뒤영벌, 우수리뒤영벌, 황토색뒤영벌, 참호박뒤영벌, 참뒤영벌과 떡벌속 2종; 대륙떡벌, 떡벌이었으며 방화가 확인된 밀원은 23종과 42종이었다. 6개의 주요도시에서 뒤영벌 여왕벌의 채집두수는 bombus ardens와 bombus ignitus가 각각 416두(72.9%)와 117두(20.5%) 채집되어 우점종이었으며, 뒤영벌의 채집시기는 각각 3월 20일∼7월 19일과 4월 7∼10.8일까지였다. 여왕벌의 중부 및 남부의 채집시기는 Bombus ardens가 부산과 지리산주변지역 및 수원지방이 3월 20일경, Bombus ignitus 외 5종은 수원 4월 7일경, 소백산·월악산과 인천 영흥도 4월 20일경, 대관령·평창 5월 20일경에 채집되어 지역에 따라 발생시기가 다르나 주로 발생초기에 채집되었다. 계절발생은 뒤영벌이 첫 출현은 진달래개화시기와 일치하며 3월에서 5월까지는 주로 진달래, 산괴불주머니, 철쭉 등을 방화하고, 6월과 7월에는 동자꽃, 비비추, 모감주나무 등 자생화를, 8월과 9월에는 무궁화, 황기, 코스모스 등을 방화하였다. Collection of domestic species of Bombini was made from March to October of 1995 to 1997 on middle and south part of Korea. The results obtained are as follows. Domestic species of Bombini, which are collected from the middle and south part of Korea from March through October of 1995 to 1997, were 9 species: seven Bombus; bombus ardens, bombus ignitus, bombus hypocrita sapporoensis, bombus ussurensis, bombus consobrinus wittenburgi, bombus koreanus, bombus opulentus and two Psithyrus; Psithyrus bonemicus, Psithyrus sylvestris popovi. 416heads(72.9%) of bombus ardens and 117heads(20.5%) of bombus ignitus were collected as the dominant species of Bombini at six major different regions. It was also found that Bombini visited 42 species of 23 Families for foraging. The collection of domestic species of Bombini in 1997 was made earlier than them in 1995 and 1996. Queens of bombus ardens were collected at the beginning stage of emergence; on the 20th of March 1997 in Pusan, Suwon and chiri Mt, queens of bombus ignitus and other species on the 7th of April 1997 in Suwon, on the 20th of April 1997 in Soback·Weolak Mt. and Inchun Younghwung Do and on the 20th of May 1997 in Daekyan Ryung·Pyungchang. The emergence of queens varied with region and species. As a phenology, the first emergence of bumblebees syncronized with the first blooming of Rhododendron mucronulatum. Bumblebees foraged on the Rhododendron mucronulatum. Corydalis speciosa, R. yedoense var. poukhanens in March to May, Lychnis cognata, Hosta longipes, Koelreuteria paniculata in June through July, and Hibiscus syriacus, Astragalus membranaceus, Cosmos bipinnatus in August through september.

Driven-Right-Leg 회로 개선에 의한 접지접촉 간섭파 제거에 관한 연구

Abstract - This study describes a method developed to reduce electromagnetic interference induced to bio-potential ECG amplifier with the Driven -Right-Leg circuit when human body contacts earth ground, accidentally. Since the contact between body and earth ground disturbs the presumed operation of the Driven-Right-Leg circuit, the ECG signal includes serious interference level, preventing ECG signal analysis by formal methods. To decrease the current flow to the Driven-Right-Leg circuit, a resistor is added between the output of the circuit and the amplifier common. Experiment has shown that the modified circuit reduces the interference level significantly both during body contact to earth ground (~1/5) and during without contact(~1/2).

This study is to analyze the performance of a radiation-panel cooling system by means of CFD. In the first step of this study, the indoor thermal environment of the office space, which is air-conditioned by radiation-panel cooling system, is analyzed by field measurement and CFD (coupled simulation of convection and radiation). With comparing the both results, the validity of the CFD method is examined from the practical point of view. In the next step, the thermal environment of the model office space, which is cooled by tree types of HVAC system (radiation-panel cooling system, all-air cooling system, and hybrid air-cooling system of radiation-panel and natural ventilation), is analyzed by CFD. By installing a human model in the room model, the characteristics of heat transfer from human are also analyzed. In the case of the radiation-panel cooling system, operative temperature and MRT(Mean Radiation Temperature) of the human model become lower than those in all-air cooling system. The radiation-panel cooling system is concluded as very energy-efficient in this study.

Some authors suggest that certain types of surfaces are the origin of such injuries. A few years after the first medical concerns about surfaces were voiced, publications of biomechanical measurements apperared, describing accleration, force, and impact measurement on different types of surfaces. In many sport activities, surfaces can be under very high dynamic load. This was the reason for the development of various methods for impact simulation, like the development of various methods for impact simulation, like the artificial athlete. Furthermore, it is important to collect information about the hardness of new and already existing surfaces in sport arenas. The idea on which this measuring system is based Is as follows: The stiffness of the material can be computed from the kinematics measurd at touch down of a rigid body onto a material sample. The results show the following The result for the artifical surfaces(Synpave ace) is surprising. It is known that these surfaces are much harder than synpave rebound classic, synpave spring. This finding suggests that it may be possible that the subjective impression is used as one criterion in the selection of landing(or style) strategies. The number of subjects in this experiment is too small to make statistically significant conclusions. It is shown analytically that when an object a deformable surface, the acceleration it experiences is inversely propotional to its mass. In future, it need to stress that the interaction between shoe and surface is important, and this aspect has now become well accepted. Considering biomechanical aspect in player's injury, it request Korean Standards for synthetic playing surfaces in sport like ASTM(America Society for Testing & Materials) standards of America, DIN 18035 standards of Germany, BSI standards of U.K.

This study has been performed to investigate into various tensile properties of Fe-1.32% Si-0.34% C steel either quenched and tempered or isothermal-transformed after austenitizing at temperatures in the range of which both ferrite and austenite are present. The results obtained from the experiment are as follows; 1) The ductility is considerably improved by the addition of Si due to the fact that ferrite solution-strengthened and the formation of precipitates in ferrite is retarded. 2) Tensile test has shown that tensile properties of specimens isothermal-transformation treated are more improved as compared to the quenching and tempering treatment. 3) The saving of heat treatment energy and the reduction of manufacturing time can be achieved by simplifying heat treatment cycles to obtain better tensile properties than those generally obtainable from dual phase steels.
