        윤형운(Hyung-Un Youn),김재은(Jae-Eun Kim),강현국(Hyun-Kook Kahng) 한국정보과학회 2001 한국정보과학회 학술발표논문집 Vol.28 No.1A

        VoIP 기술은 사용자 사이에서의 call을 설정, 변경, 종료할 수 있는 signaling 프로토콜이 필수적이다. 이러한 점에서 인터넷 프로토콜 네트워크 상에서의 call과 멀티미디어 세션의 실시간 제어를 목적으로 IETF의 MMUSIC WG에서 만들어진 새로운 signaling 프로토콜이 SIP(Session Initiation Protocol)이다. 또한, IETF에서 SIP WG이 생겨나면서, 이 프로토콜에 대한 연구가 더욱 활발해지고 있다. 본 논문에서는 SIP에 대한 개략적인 내용과 SIP 프로토콜의 기능들을 간략하게 소개하였고, SIP의 session initiation의 과정과 registration 과정 등의 동작에 대하여 설명하였다. 그리고, User Agent의 기본적인 동작을 설명하고, VOVIDA에서 개발한 SIP의 리눅스용 공개 소스를 통해서 User Agent 의 실행되는 과정을 분석하였다.

        This study aimed at an evaluation of the reliability and validity of Ewha Defense Mechanism Test(EDMT) for standardization during the period from June 25 to July 10 with nationalwide sample which was standardized by Rhee Kun Hoo. Kin Jae Un. Kim Jung Kyu. and Park Young Sook. The number of subjects were 1.323 who were sampled by the method of proportional stratification on age. sex. education. local area variables. This test is composed of 20 defense mechanism subscales and total items of the test are 200. The results were as follows : 1) The range of means of each scales were from 2.70 to 3.34 and the range of items standard deviation was from .71 to 1.28. 2) The corrected item-total correlation coefficients were than .10 for all items except two items which was the index of internal consistancy. 3) The spearman-Brown split-half reliability coefficients were more than .66 and the retest reliability coefficients were more than .72 for all scales. 4) By the evaluation of the cross validation with “16 Personality Factor Inventory”. it was found that 11 factors were consistent with expectation among 16 factors so that the result of cross validity was moderately sufficient. 5) By the factor analysis. four factors were extracted. Factor 1 was “unstable sensitization defense mechanisms”which were acting out, displacement, somatization. dissociation. projection. and passive-aggressive behavior. Factor 2 was “ego-expansive defense mechanisms” which were composed of controlling. distortion. altruism. humor. and sublimation. Factor 3 was “ego-denial defense mechanisms” which were reaction formation. bragging identification. and regressin. Factor 4 was “reality evasive defense mechanisms” which were denial rationalization. suppression. anticipation. and evasion.

      • 敎育課程 構成을 爲한 基礎硏究(I) : 學生ㆍ敎師의 要求 分析

        金在恩,康宇哲 이화여자대학교 한국문화연구원 1969 韓國文化硏究院 論叢 Vol.13 No.-

        Ⅰ. Outlines of this survey 1. Our ministry of education has so far enacted curriculum for various school systems only depending on conferences and formal discussions. We have felt urgent need for basic survey for most reasonable and vital curriculum development. Then we have launched a series of studies for such purposes, and that this survey was planned as the first project of that series. Those series are (1) philosophical and historical valuation (2) social forces and impact (3) students, needs and problems (4) functions of subject matters, and (5) learning theories. 2. We dealt here with those problems as (1) students' educational needs (2) Teachers' evaluation and opinions. 3. Subjects are 1,268 students in all, 253 from primary school, 287 from middle school 261 from general high school, 50 from comprehensive high school, 119 from commercial high school, 60 from fishery high school, 119 from agricultural high school. Teachers are 139 in all with whole caverage of above schools and with the areal consideration. Ⅱ. Results 1. Primary school children : Primary school children have most keen interests in nature and science, various social facts and chages too. In contrast with those interests, they have little interests in business and arts. The troubles which they have are poor achievement of arithmetics and fine arts. They have broad vocational interests regardless their community background and sex. 2. Primary school Teacher : They reported that children like sports but dislike arithmetic and business. Teachers observed lack of knowledge of fine arts, lack of the abilities to apply what they learnt, and lack of creativity. Teachers enumerated many problems children have from poverty up to lack of confidence upon teacher. They wanted to have more concrete and clear-cut educational objectives in teaching and guidance. 3. Middle school student : Students have broad span of interests in school subjects and extra-curricular activities too. Student do not like uniform or compulsory training and school activities, and ask teachers to be more familiar with students. They have many and various troubles at home and school, so they have to be helped by teachers for solving their problems. They want independence from parents and teachers and mostly are dissatisfied with their school life. Their span of interests in extra-curricula activities and vocations are so broad that teachers should take those facts into consideration in their guidance programs. 4. Middle school Teacher : Teachers reported that students have much interests in opposite sex relations, current events, and many extra-curricular activities as well. Their disciplinary problems span from opposite-sex relation to general morality. Most serious troubles students have are tuition fees, allowances, overloaded curricular, maladjusted school life. Teachers observed students' negativistic, dependent attitudes as most serious shortage in students' attitudes. 5. High school Students : High school students have much broad interests span and show much regional and sexual differences in those interest areas. They want independence and freedom from teachers' compulsion and parents' restriction. They have troubles in poor achievement, poverty, poor home atmosphere, parents' lack of understanding and so forth. They like to have more deep understanding on modern scientific and social advancement and changes. Their vocational interests range from merchant up to presidency. There are great regional and sexual and school differences in those vocational interests. 6. High school Teacher : Teachers reported that opposite sex relations, sex education, and resistance are most serious disciplinary problems at high school level students. Students' way of thinking are seen as to be calculative, egoistic and looseminded. They assert that most emergent takes to be done for high school students are to provide more reasonable guidance programs and democratize educational practices at the home and school.

      • 人物畵에 依한 知能測定 : 知的發達의 硏究 및 몇가지 技術報告

        1. The purpose of this study is to picture a pattern of intellectual development of children through five to twelve years of age by Goodenough Draw-a-Man Test which had been revised and extended by Harris, D.B. in 1963 after the death of Goodenough. In Korea, Goodenough-Harris Draw-a-Man Scale was first applied to Korean population by this writer though several previous studies with Goodenough's old scale had already been made these ten years. 2. In the former part of his paper, a brief description on the assumption and nature of Goodenough's original seale and Goodenough-Harris revised scale were made, and in addition to that a few such studies in Korea were mentioned briefly. Korean conversion scale was standardized to 1,523 boys, 1,418 girls, 2,941 children in all throughout the whole nation. I prepared two regional norms, large city and provisional norms, and one national norm so as to read scores according to sex and age levels separately along with two equivalent forms. 3. Results 1) Mean and standard deviation of score distribution of large city and provincial samples increase with age progression in both male and female figures, but big regional differences were found between two regions especially in female figures. Boys exceeded slightly girls in male figure but girls exceeded greatly boys in the female figure. Changes of pattern of growth curves came out almost in same shape between sexes and regions as well. These facts are supposed to mean that this DAM Test can make a age discrimination considerably well so that it can be judged to be applied to Korean populations. 2) Forms of age progression describe the facts that the curves gradually go upward between 5 to 6, accelerate between 6 to 8, again decelerate between 8 to 12 years of age. 3) Some comparisons of forms of curves were made between this study and some other similar studies, but there seem not to be any coincidences among studies. 4) Concepts of body parts develop on several stages: the first stage (5 years old) comprises: head, eyes, nose, mouth, hair, arms, legs, and trunk, the second stage (6 years old); foot, connection of arms and foot, the third stage (7 years old); costume, proportion of the trunk, the fourth stage (8 years old); nose (two dimensional), fingers, the fifth stage (9 years old); hair Ⅱ, the sixth stage (10 years old); shoulder, the seventh stage (11 years old); foot (two dimensional), moving arms, the eighth stage (12 years old); neck, connection of arms and legs, neck (two dimensional) hip. These stages form a sequences of development of body concept at boys and girls between 5 to 12 years of age. 5) Reliability of scorers came out as .92-.97 in age group of 7 &11, & that of between equivalent forms (that is, between male and female scores) are .75-.80. 6) Cross-validation was tried with drawing scores at school, with mental maturity test scores and with school grade point; the results are: Validity 〓〓〓〓〓〓〓〓〓〓〓〓〓〓〓〓〓〓〓〓〓〓〓〓〓〓〓〓〓〓 Criteria | Correlation(r) |_______________ | Min. Max. Med. ______________________________ Drawing Scores (fine art) | .21 .50 .44 Mental Maturity Test | .35 .42 .38 School grade Test | .21 .45 .39 ______________________________

      • 한국 유아의 成長ㆍ發達의 類型 : 유아의 運動發達의 연구

        金在恩 이화여자대학교 한국문화연구원 1975 韓國文化硏究院 論叢 Vol.26 No.-

        The present study aims at surveying the motor developments of Korean infants by a check-list including 75 items sampled from several previous studies of the same kind in other countries. The subjects were mothers having infants ranging from 0 months to 24 months of age. They were sampled from a nation-wide population excluding Cheju-Do Province. One-hundred and forty infants were observed. The characteristic motor abilities were checked as percentages in each three month unit; for example, 0-3, 3-6, up to a 13-15 month unit. The results showed very similar characteristics and trends in each age unit with the previous studies conducted in the United States and Japan. But one prominent fact found in this study was the delay of prehension and creeping movements. This fact implies the lack of experience of this movement in infancy.

        金在恩,金泰蓮 이화여자대학교 한국문화연구원 1981 韓國文化硏究院 論叢 Vol.39 No.-

        This study aims firstly at finding out the main patterns of aggression of Koreans in frustrating situations. The authors analysed three reaction patterns (obstacle-dominance, ago-defense, need-persistence) and three directions of reaction (extrapunitive, impunitive, intra-punitive). Secondly, this study aims also at restandardizing the existing norms and analysis scheme of Picture Frustration Test in order that this PFT can be applied to picturing out the subjects personality characteristics more realistically and validly.
