N/A Research in the field of biosensor has enormously increased over the recent years. The metal-oxide semiconductor field effect transistor (MOSFET) type protein sensor offers a lot of potential advantages such as small size and weight, the possibility of automatic packaging at wafer level, on-chip integration of biosensor arrays, and the label-free molecular detection. We fabricated MOSFET protein sensor and proposed the gold-black electrode as the gate metal to improve the response. The experimental results showed that the output voltage of MOSFET protein sensor was varied by concentration of albumin proteins and the gold-black gate increased the response up to maximum 13 % because it has the larger surface area than that of planar-gold gate. It means that the expanded gate allows a larger number of ligands on same area, and makes the more albumin proteins adsorbed on gate receptor.

자기조립 단분자막을 이용한 MOSFET형 단백질 센서의 제작 및 특성
한승우 ( Seung Woo Han ),박근용 ( Keun Yong Park ),김민석 ( Min Suk Kim ),김홍석 ( Hong Seok Kim ),배영석 ( Young Seuk Bae ),최시영 ( Sie Young Choi ) 한국센서학회 2004 센서학회지 Vol.13 No.2
N/A Protein and gene detection have been growing importance in medical diagnostics. Field effect transistor (Phi`) - type biosensors have many advantages such as miniaturization, standardization, andmass-production. In this work, we have fabricated metal-oxide-semiconductor (MOS) FET that operates as molecular recognitions based electronic sensor. Measurements were taken with the devices under phosphate buffered saline solution. The drain current (I_(D)) was decreased after forming self-assembled mono-layers (SAMs) used to capture the protein, which resulted from the negative charges of SAMs, and increased after forming protein by 11,5% at V_(G)= 0 V due to the positive charges of protein.

초등학생의 과외학습 스트레스가 학습태도 및 학습습관에 미치는 영향
허지원(Heo Ji-Won),이동훈(Lee Dong Hun),황윤원(Hwang Yoon-Won),김홍석(Kim Hong-Seuk) 경성대학교 인문과학연구소 2010 인문학논총 Vol.15 No.1
본 연구에서는 부산지역 초등학생 5, 6학년 364명을 대상으로 초등학생의 과외학습 실태 및 과외학습에 대한 인식을 알아보고 과외학습 스트레스가 학습태도 및 학습습관에 미치는 영향을 알아보았다. 그 결과 과외학습 스트레스 하위요인 중 시간적ㆍ심리적 부담이 높을수록 학습태도에 부정적 영향을 미치며 특히 학업영역이 부정적인 것으로 나타났다. 또한 과외학습 스트레스 하위요인 중 시간적·심리적 부담과 시간적 자율성 제약에 의한 스트레스가 높을수록 학습습관이 부정적인 것으로 나타났다. 과외교사와의 관계 및 시간적 자율성 제약에 의한 과외학습 스트레스가 높을수록 학습습관 중 주의집중행동이 부정적임을 알 수 있었다. 시간적ㆍ심리적 부담과 시간적 자율성 제약에 의한 과외학습 스트레스가 높을수록 자율학습행동에 어려움을 겪고 있는 것으로 나타났다. 이러한 연구결과에 기초하여 논의 및 연구의 함의가 제시되었다. The purpose of this study is to examine the influences that elementary school students’ stress experienced from extracurricular learning activities after school has on academic attitudes and study habits. There is a negative correlation between stress experienced from extracurricular learning activities after school and students displaying academic attitudes. 'Burden on time management and psychological uncomfortableness', a subfactor of extracurricular learning stress, was only the predictive variable of negative academic attitudes. There is a negative correlation between extracurricular learning stress and students displaying study habits. Two sub-factors of extracurricular learning stress, 'Burden on time management and psychological uncomfortableness', and 'limitations of time use and autonomy' were only the predictive variables of negative study habits. Findings and implications are discussed.

繪畵에 있어서 Gesture Painting과 Color Field Painting에 對한 考察 : 美國抽象表現의 1940~1950年代를 中心으로
金洪錫 釜山敎育大學 1984 부산교육대학 논문집 Vol.20 No.1
The aim of this paper to make clear of the two simultaneous inclinations to the abstract expression in America is how to simultaneously solve the problems between the old tradition and the new tradition, and the intellect and the emotion in the regional feature of America, and what kind of inclination and innovation in style their artistic intention and belief make. To these points this paper is divided into two chapters. 1. The simultaneity and the originality of the abstract expression in America. 2. The structure and the pictural character of the gesture painting and the color field painting Out of these discourses, we have the following points. 1) In fact, American abstract expressionists formed a loose group, this group thoroughly understood and inquired one another's work with the new innovative energe, and it formed and closely understood, what is called, Robert Mothetwell's "The underlying nework of awareness" and Herbert Read's "The direction of multiple energies",. This tight cultural relation of the American expressionism was very persnal and very general as well. 2) In production of art, because the term "generation" was publicly mentioned among those who played a partial role at the same days and hed more or less the same sense with one another, some conceptions were unavoidably used as a single-handed, therefore this generation-the first generation-was nationally and internationally aknowledged as it's growth and. thought as the creative conception in the range of the American initiative art innovation and the first source vitalizing it's creative conception and world. And many Masters-Pollock, de Kooning, Gorky, Motherwell, Rothko, Newman, Still, Rainhardt, Gottlied, ete. -established the panthcon of American paintinghistory. 3) The abstract expression in American painting The gesture painting and the color field painting - had many problems and much influence on the coming generation. These two inclinations which simultaneously formed on the same period have embraced till these days like tides Which runs on each other direction from large one. As we have seen, the two simultaneous inclinations created the new tradition to search for the artistic capacity and these clearly had the American accent. And these researches must be carefully made for a long time.

본 연구는 우리 나라 창업보육센터의 전반적인 운영실태를 평가함과 아울러 향후 보육센터를 체계적으로 발전시켜 나가기 위한 정책방안을 제시하는데 목적을 두고 있다. 이를 위해 본 연구는 구조화된 설문조사서를 이용한 직접방문 면접조사를 통해 중소기업청이 1999년도까지 창업보육센터로 지정한 총 142개소 중 평가 가능한 134개 보육센터의 운영능력 및 지원서비스 부문을 평가하였다. 평가대상 창업보육센터는 센터의 유형, 운영주체, 재원조달 방법, 운영시기 등이 상이하였기 때문에, 센터 운영의 '적합성'과 '효과성'이라는 개념을 평가에 도입하였다. 그러나 평가시점에서 대부분의 창업보육센터가 설립 후 2년이 경과되지 않아 두 개념을 동시에 적용하는데 문제가 있어 본 연구에서는 우선 창업보육센터의 발전 잠재력을 중점적으로 평가한다는 측면에서 '적합성'의 개념만을 평가에 사용하였다. 본 연구는 보육센터에 대한 평가결과를 바탕으로 향후 우리 나라 창업보육시책의 체계화 및 보육센터 운영의 내실화를 도모하기 위한 정책방안을 제시하였다. The purpose of this study is to assess the overall operation and performance of Korean business incubators and to suggest possible government policies to systematically assist them. For this purpose, this study examined the management abilities and support services of 134 respondents from a total of 142 incubators which Korea Small & Medium Business Policy Bureau approved as of 1999, through direct interviews with management and tenants using a structured questionnaire. This study also developed two criteria-fitness and effectiveness-for the assessment as the incubators varied significantly in terms of type, founder, method of financing, and length of operation, etc. The study concludes with some policy recommendations for both the readjustment of government support policies for business incubators and improving their operational effectiveness.
