The occuring rate of the myopia (near-sight) is 8.74 in Korea school children, and 16% of fresh pupils of school for the blind are partially seeing and three increase every year. But doesn't established appropriate educational service for them. Some results of into a educational program for the partially seeing are as follows. 1. The educational pratially seeing are those who have a visual acuity between 0.04 and 0.3 in the both eyes and the occruing rate is about from 0.12% to 0.12% 2. Since special educational service for the partially seeing began in U.S.A. (1913) and Japan(1932), the Sight-Saving class has developed to various types such as the cooperative class plan. 3. In general the peronality of the partially seeing is quite same with that of the nermally seeing. There is no meaningful differences of I.Q on each groups, but the partially seeing is more introversive, often has day dreams and a little retarded on achievement. 4. Aims of education for the partially seeing is same with that of normally seeing. Sight Saving and utilizing residual senses should be empahasized. 5. It needs to take notice of use Large printing books, references, and appropriate class room light (20 candle power), and magnifying glasses, should be needed for them, that to be supplements of seeing aids. And it is also needful to teach them on individualized program. 6. To promote educational planning and practive of education for the partially seeing, it is needful to study the dontinous survey of partially seeing, developing psychological test, educational materials and teacher's educational program. A Comparative study on the rising attitude of parents of mentally retarded and crippled children. Rhee, Sang Chun, YoungHa. Won, Myung uk, Chun, Joe ill. Park, ok su. Rhee, Jae Ho. (Daegu School for the Memtally Retarded Abstract Looking into that kind of attitude that parents of the mentally retarded and the crippled children have, will be of much meaning in largely effecting the attitude of these childrens parents. The purpose of this study is as follows. 1. Consideration of the difference of the rising attitudes of parents of mentally retarded and crippled children. 2. Considertion of differences of the attitudes of fathers and mothers of crippled children. To accomplish the above purpose a questionaire was prepared The questionaire consisted of ten catagories of different attitudes, each catagory divided into ten questions, making a total of 100 questions. This was then sent to each family requesting them to answer. This questioraire surveyed the attitudes of 100 parents of children attending Daegu school for the mentally retareded and 62 parents of children attending Daegu school for the crippled. A CR test was done on the survey and the results were diagrammed. The results are as follows. A. The parents of the mentally retarded and the crippled children displayed 4 different attitudes towards rising their children. They are passive and rejecing type, a "doting-upon" type, an "obeying type", and a disagreeing type." In the result of CR test appeared significant differentials at P <. 001 level in types and the significant differentials at P < 0.1 level in active rejective types. These five types are on the more dangerous areas in the parents of the mentally retarded than the crippled children group. B. Between the father's and mother's attitude of the crippled children's group, there was displayed no significant differences in statistics. They were in both the dangerous are a concerning the anxious "doting-upon" and the obeying types.
Recently, the first generation of mass production of FinFET-based microprocessors has begun, and scaling of FinFET transistors is ongoing. Traditional capacitance and resistance models cannot be applied to nonplanar-gate transistors like FinFETs. Although scaling of nanoscale FinFETs may alleviate electrostatic limitations, parasitic capacitances and resistances increase owing to the increasing proximity of the source/drain (S/D) region and metal contact. In this paper, we develop analytical models of parasitic components of FinFETs that employ the raised source/drain structure and metal contact. The accuracy of the proposed model is verified with the results of a 3-D field solver, Raphael. We also investigate the effects of layout changes on the parasitic components and the current-gain cutoff frequency (fT). The optimal FinFET layout design for RF performance is predicted using the proposed analytical models. The proposed analytical model can be implemented as a compact model for accurate circuit simulations.
This study investigated the consequences of the mass higher education in Korea and university student selection mechanisms. The study used the data from the Korean Census Population Reports(1966-1985) and Ministry of Education Yearbooks(1966-1988). The case study used the data from the dropout students of one university in Records(1978-1989). It was found that the university entrance rate in age group (18-21) increased from 3.8%(female, 29%) in 1966 to 17.9%(female, 12.4%) in 1985. The characteristics of higher education changed from the elite model to mass model, but the Korean mass higher education in inequal in sex group, age group, and community size. The university student seletion mechanisms were analysed into three stages:entrance examination-grade promotion-graduation. The rate of university entrance to applicants is 25%(female, 28%) in 1988, and that of entrance to re-examiners is 19%(female, 20%). The rate of absentee students is 14%(female, 3%) and the reinstate rate of them is 70%(female, 85%) in 1987. The rate of dropout students is 2%(female, 2%). And the rate of reentrance to them is 14%(female, 16%). In the case study data from the entrance student groups in 1983, the grade promotion rate form freshmen to sophomore is 105%(female, 100%), sophomore to junior 121%(female, 93%), junior to senior 71%(female, 97%), senior to graduation 76%(female, 99%0, and freshman to graduation 68%(female, 88%). And in the case study data from the dropout students of the university in Records(1983), the male is 74%, and the re-entrance rate is 20%. The rate(58.2%) of dropout students majored in Natural Sciences or Engineering is higher than that of dropout students majored in humanities or Social Sciences. In the high school types of dropout students, general high schools(84%) are much more than vocational high schools. The SES of dropout students is low middle(41%)
In this paper, an analytical model is presented for the source/drain parasitic resistance of FinFET. The parasitic resistance is a important part of a total resistance in FinFET because of current flow through the narrow fin. The model incorporates the contribution of contact and spreading resistances considering three-dimensional current flow. The contact resistance is modeled taking into account the current flow and parallel connection of dividing parts. The spreading resistance is modeled by difference between wide and narrow and using integral. We show excellent agreement between our model and simulation which is conducted by Raphael, 3D numerical field solver. It is possible to improve the accuracy of compact model such as BSIM-CMG using the proposed model. 본 논문에서는 RSD(Raised Source/Drain)구조를 가지는 FinFET에서 3차원적 전류 흐름을 고려한 소스와 드레인의 해석적 저항모델을 제시한다. FinFET은 Fin을 통해 전류가 흐르기 때문에 소스/드레인의 기생저항이 크고 채널을 포함한 전체저항에서 중요한 부분을 차지한다. 제안하는 모델은 3차원적 전류흐름을 고려하여 contact부터 channel 직전 영역까지의 소스/드레인 저항을 나타내며 contact저항과 spreading저항의 합으로 이루어져 있다. Contact저항은 전류의 흐름을 고려한 가이드라인을 통해 작은 저항의 병렬합으로 모델링되고 spreading저항은 적분을 통해 구현했다. 제안된 모델은 3D numerical solver인 Raphael의 실험결과를 통해 검증했다. 본 연구에서 제안된 기생저항 모델을 BSIM-CMG와 같은 압축모델에 구현하여 DC 및 AC 성능 예측의 정확도를 높일 수 있을 것이다.
This study is to sugges a way of improving the models of technical manpower development plan in Korea by looking into the demerits of its current system. From the writers investigation, the present models largely rely on vocational schools and colleges for recruiting technical manpower. This is considered to be an undesirable method for our government to employ. The writer, therefore, suggest a more ideal model which comprises the secodary channels as well as the first ones. There is no doubt that the National Qualification Examination System has so far made a greate contribution to the enhancement of the tecnicians' qualification and their social status, and it has also improved the education of vocational schools. However, it has been one of the causes to bring forth an unhappy atmospher where almost all the vocational schools exert themselves to prepare the students only for the examination during the academic years. In order to inprove this unfavorable condition the writer suggests the ideal number of subjects to be tested on and the method of administering the examination.

No individual life is free from social and historical change. War is one of the strongest factors which occur changes in society in a great scale. The effects of war on individual lives seem to be various according to such conditions as gender, age, socio-economic backgrounds and so forth. This paper examines the effects of Korean war on women's lives based on oral histories of seven women who experienced the Korean War as unmarried and nineteen to twenty-five year old girls. Especially, this study focuses on the ways in which the Korean War affected experiences of economic activity of these unmarried women. The oral history interviews conducted on these seven women show the ways in which women experience works, and also the process and characteristics that they selected jobs and continued or discontinued their work career by the war in terms of motives and kinds of jobs and occupations. Besides, this study looks into the ways in which their family and parents consider their daughter's work as a family strategy in the social dislocation of wartime. Moreover, it examines how these women remembers their work experiences in relation to war and give meanings to their economic activities. Exploring these matters through women's oral history, this paper attempts to explore the characteristics of labor participation and work patterns during the Korean war and the effects of the war made to unmarried women who experienced the war in their early twenties compared to other generations of women.
