1. Objectives and Methods The purpose of this study was to objectify the diagnosis of Sasang constitution. It analyzed the adult male and female voices into 23factors using PSSC-2004. The study was conducted by subjects inputting 2.5-3 sec of [a] in 586 men and women's voices to PSSC-2004. The statistical analyses are applied to three groups: total group, male group, female group. The group with a total of 586 was composed of 155 Soyangin, 230 Taeumin and 201 Soeumin. The male group was composed with 61 Soyangin, 127 Taeumin and 87 Soeumin. The female group was composed with 94 Soyangin, 103 Taeumin and 114 Soeumin. Taeyangin were excluded for a more accurate statistical analysis. 2. Results (I) In total group, Taeumin's peak sum was significantly high compared with the others(P=0.021). It was significant for distinction between Taeumin and Soyangin at the result of post mortem. (2) In total group, the Soyangin's rank6, rank7 and rank8 were significantly high compared with the others (P=0.050)(0.043)(0.034). (3) In total group, the Soyangin's rank9 was significantly high compared with the others(P=0.025). It was significant for distinction between Taeumin and Soyangin at the result of post mortem. (4) In male group, the Soyangin's code3 was significantly high compared with the others(P=0.050). (5) In male group, the Soyangin's code1 was significantly low compared with the others(P=0.004). It was significant for distinction between Taeumin and Soyangin at the result of post mortem. (6) In male group, the Soyangin's rank1, rank2, rank3 and rank4 were significantly high compared with the others(P=0.017)(0.008) (0.005)(0.002). They were significant for distinction between Taeumin and Soyangin at the result of post mortem. (7) In female group, the Taeumin's code1 was significantly low compared with the others(P=0.016). It was significant for distinction between Taeumin and Soeumin at the result of post mortem. 3. Conclusion From above result, there is the possibility of efficiency standard gide for constitutional diagnosis by analyzation of the voices.

학습 성과를 기초로 한 공학교육은 반드시 한국공학교육인증원의 인증을 위해서 그 필요성이 존재하는 것은 아니다. 실제 공학 교육에서 교육의 개선과 발전을 위한 매우 유용하고 효과적인 방법임을 부인할 수 없으며 세계적 교육의 대세인 것이다. 본 연구는 학습 성과를 달성하기위한 일반적인 교육 방법과 "평생학습"에 대한 예를 제시하고자 하였다. 학습 성과를 달성하기 위한 순서와 구성요소, 또 교육의 새로운 패러다임인 CQI(continuous quality improvement)를 달성하기위한 소위 "close-the-loop"의 예도 제시하였다. Outcomes based engineering education is not necessary only for the accreditation by the ABEEK, but the actual improvement and enhancement of the engineering education. Also, it is the new and big trend in engineering education filed world widely. The new methodology for performing outcomes based education has been proposed for engineering education and the practical application for so called 'life-long learning' outcome has been presented. Furthermore, the way to 'close-the-loop' for CQI(continuous quality improvement) in engineering education has been shown.

김명랑,윤우영,이경훈,Kim Myoung-Lang,Yoon Woo-Young,Lee Kyung-Hoon 한국공학교육학회 2004 공학교육연구 Vol.7 No.1

One of important criteria of an engineering certification is the outcomes. This study proposes a result of satisfaction for twelve's outcomes and improvement of engineering education curriculum to achievement of the outcomes. According to the research, students over 74%s have been satisfied. And we could get the conclusion which the general and design education must be strengthened more to achievement of the outcomes. 한국공학교육인증원(ABEEK)에서는 공학 인증의 중요한 기준의 하나로 학습 성과(outcomes)를 제시하고 있다. 본 연구는 12가지 학습 성과에 대한 만족도를 조사하여 학습 성과를 달성하기 위한 공과대학의 교육 과정의 개선 방향을 제시하고자 한다. 연구 결과에 따르면 74% 이상의 학생들이 만족하고 있었고, 학습 성과를 달성하기 위해서는 설계 및 교양 교육이 더욱 강화되어야 한다는 결론을 얻을 수 있었다.

N/A The miscibility gap in the monotectic system results in a macro segregation due to the gravity. In this study, the homogenization number, H was introduced to predict the condition of producing the homogeneous alloy which has fine, well-distributed minor particles in the matrix. Nucleation, particle growth, surface energy, sedimentation, flotation, and free convection were taken into account to develop the dimensionless H number. The H number was calculated numerically on various g-levels, cooling rates, sample sizes, and alloy compositions. Simulation results showed that homogeneity of the monotectic alloy was affected mainly by miscibility gap(composition), decomposition time and gravity.

포트폴리오는 학생들이 비교적 오랜 교육기간 중에 수집한 학습결과물을 의미하며, 교육과정 이수 후의 학생들의 성취도를 잘 반영할 수 있고, 교육과정을 개선하고 다시 검토하여 프로그램을 되돌아 볼 수 있는 좋은 기회를 제공하는 이점을 지니고 있다. 이러한 포트폴리오의 평가방법으로서의 우수성을 공학교육의 프로그램학습성과 성취도 평가에 이용하려면, 본 기법에 대한 정확한 이해를 바탕으로 우리 교육 실정과 공학교육 프로그램의 특징을 살펴 적용하여야 한다. 따라서 본 연구는 공학교육 프로그램의 학습성과 평가도구로 학생 포트폴리오를 제안하며 실제 모델을 구축하여 프로그램학습성과 평가의 새로운 기법으로서 활용하고자 하였다. Portfolio contains works that a learner has selected and collected to show growth and change for a limited time period. In terms of an assessment tool, portfolio provides the results of the student with authentic, reflective, interactive and individuals features. Also portfolio provides an opportunity of improvement about curriculum and engineering program. To apply the excellency of portfolio, the principle of portfolio should be understood well and reflected the real state of engineering education. The basic concept of portfolio as a assessment tool of engineering program outcomes was introduced. The example of a portfolio has been also suggested in the form of interactive e-based model. The model has been developed that the assessment for program outcomes was rather done from a student standpoint.

이미 여러 분야에서 모집단의 실향에 대한 질적 평가 방법 중 우수하다고 정립이 된 조사기법인 '초점그룹(focus group)'을 공학교육의 학습 성과의 성취도 평가에 이용하려면, 본 기법에 대한 정확한 이해를 바탕으로 우리 교육 실정과 공학 교육의 특징을 살펴 적용하여야 한다. 본 연구는 '초점그룹'에 대한 소개와 함께, 공학 교육의 학습 성과 평가에 활용할 때 제기될 수 있는 문제점들을 파악하고 대안을 제시함으로서, 학습 성과 평가의 새로운 기법으로써 '초점그룹'을 활용하고자 하였다. 조사 기획, 실행, 분석 단계에서 일어날 수 있는 문제점들을 정리하고 가능한 해결 방안에 대해 연구하였다. 실제 공학교육에 적용을 위한 실행에 이용할 수 있도록 조사 지침서의 간단한 예도 연구 제시하였다. The 'focus group' is a well established methodology to evaluate the characters and features of the mother group qualitatively. In outcomes based engineering education, it is a key issue to select a proper tool for evaluating the achievement of outcomes. Based on understanding of the method. A 'focus group' was introduced to evaluate the outcomes qualitatively in the engineering education. The issues in the procedure, implementation and analysis were studied. The guide manual for specific outcomes (life-long learning, contemporary issue, cooperation world-widely) was also suggested.

급속응고된 금속분말의 응고거동 및 제조법에 관한 연구 ( Part 1 : 급속응고 제조법 )

김종윤,윤우영 ( Jong Yoon Kim,Woo Young Yoon ) 한국주조공학회 1995 한국주조공학회지 Vol.15 No.2

N/A New metallic powder making processes, named Centrifugal Emulsification Process(CEP) and Mixer and Settler(MS) have been developed to synthesize rapid solidified metallic powders. Through CEP and MS processings, the high temperature metals as well as the low temperature alloys are manufactured. Also, the effects of rapid solidification on the undercooling, solidification rate and crystallization behaviors can be evaluated effectively through the processes. The standard deviations of the synthesized typical Pb-Sn eutectic powders are 1.63 and 1.51 for CEP and MS respectively, and the average size of the MS powders was 18㎛. The possibility of the customized not only size and shape control but microstructure control was also shown. Both of the new methods can be applied to continuous powder making processes.

Fractional Melting 에 의한 Si 정련에 관한 연구

김귀욱,윤우영 ( Kwi Wook Kim,Woo Young Yoon ) 한국주조공학회 1997 한국주조공학회지 Vol.17 No.6

N/A Fractional melting process involves heating an alloy within its liquid-solid region simultaneously ejecting liquid from the solid-liquid mixture. The extent of the purification obtained is comparable to that obtained in multi-pass zone refining. The new fractional melting process in which centrifugal force was used for separating the liquid from the mixture has been developed and applied to the purification of the metallic grade. Refining ratio depends on partition ratio, cake wetness and diffusion in the solid, and it was controlled by various processing parameters such as rotating speed and heating rate. The new parameter called refining partition coefficient has been suggested to estimate the effects of processing variables on the refining ratio. Because major impurities in MG-silicon such as Fe, Al, Ni have a low segregation coefficient, good purification effect is expected. The results of refining MG-silicon(98%) showed that 3N-Si was obtained in refined solid of 50% of the original sample. (Received November 10, 1997)
