Usability heuristics는 사용자 인터페이스를 설계하는 과정에서 유용성 평가에 사용되는 일반적인 원칙이다. 유용성 평가 방법은 보통 Human Computer Interaction(HCI) 전문가들이 사용하는데, 이 연구의 최종적인 목 적은 HCI 전문가들 뿐 만이 아니라 사용자 인터페이스를 제작하는 더 광범위한 많은 사람들(사용자 인터페이스 디자이너나 엔지니어들)에게 적용하는 것이다. 따라서 본 연구에서는 유용성 평가에서 대표적으로 사용되는 Jakob Nielsen의 10가지 usability heuristics가 HCI 전문가가 아닌 디자인과 컴퓨터 공학 교수 및 학생들이 얼마나 이해하기 쉬운지를 설문하였다. 또한 응답한 설문을 바탕으로 어떤 heuristics들이 이해하기 쉬었으며, 이해하기 어려운 것들은 어떠한 이유로 이해하기가 어려웠는지, 또 교수들과 학생들과의 이해정도의 차이나 응답반응의 차이 등을 분석하였다. 본 연구를 통하여 얻게 된 가장 큰 성과는 응답자들이 좀 더 사용자 입장에서 어플리케이션들을 바라볼 수 있게 되었다는 점이었으며, 본 연구의 결과들은 usability heuristics를 좀 더 많은 사람들이 쉽게 이해할 수 있도록 만들어서 인터페이스를 설계하고 구현하는데 도움이 될 것이다. Usability heuristics(“heuristics”) are general principles for usability evaluation during user interface design. Our ultimate goal is to extend the practice of usability evaluation methods to a wider audience(e.g. user interface designers and engineers) than Human Computer Interaction(HCI) professionals. To this end, we explored the degree to which Jakob Nielsen`s ten usability heuristics are understood by professors and students in design and computer engineering. None of the subjects received formal training in HCI, though some may have had an awareness of some HCI principles.

본 연구는 중학생들의 스포츠클럽 참여에 따른 신체적 자기개념과 학교생활만족도의 차이를 알아보고 스포츠클럽 참여 중학생의 참여정도가 신체적 자기개념에 미치는 영향을 분석하였다. 부산교육청 산하지역 내 스포츠클럽을 실시하고 있는 10개 중학교를 모집단으로 선정하였고 유목적 할당표집법을 이용하여 조사대상의 표본을 추출하였다. 총 347부의 자료를 수집하여 변수들 간의 구성요인들의 단일차원성 확인을 위하여 연구 단위별로 직교회전방식에 의한 Varimax 방법을 사용하여 주성분 분석방법을 실시하였으며 신뢰도 검증은 이론 변수의 다측정 항목간의 내적 일관성을Cronbach's a값에 의한 분석방법을 채택하였다. 본 연구의 결론은 다음과 같다. 1) 중학생의 스포츠클럽 참여에 따른 신체적 자기개념과 학교생활만족도의 인식차이에서 참가자의 신체적 자기개념 하위요인인 외모, 유연성, 규칙적 운동, 근력, 지구력에서 통계적으로 유의한 차이가 나타났다. 그리고 스포츠클럽 참여에 따른 학교생활만족도에서 스포츠클럽 참여 학생이 비 참여 학생들보다 교사관계, 수업일반, 교유관계가 더 높은 것으로 나타났다. 그러나 학교의 물리적 환경에는 통계적으로 유의한 차이가 나타나지 않았다. 2) 스포츠클럽의 참여정도가 신체적 자기개념에 미치는 영향에서 참여빈도,, 강도, 기간은 신체적 자기개념의 하위요인에서 유의한 차이가 나타났다. 즉 외모, 유연성, 근력에 미치는 영향은 부분적으로 수용되었고, 건강, 체지방, 지구력은 기각되었다. The purpose of this study was to investigate the difference of physical self concept and satisfaction of school life, and the effect of the degree of participation in middle school sports clubs on the physical self-concept of middle school students. The participants of the study were from ten middle schools which host various sports clubs under the guidance of the Busan Metropolitan City Office of Education. Test samples were extracted by using a purposed sampling method, and the Varimax method was conducted after gathering 347 data. In order to obtain reliability, Cronbach’s value was conducted using the variable’s consistency among the multi measurement. The results are as follows. First, physical self concept affected external appearance, flexibility, regular exercise, muscular strength and persistence after participating in sports clubs. According to a survey on physical self concept and satisfaction of school life, the students who participated in sports clubs had a positive relationship with the their teachers, as well as with their friends than those who did not. However, the physical environment or the school was not statistically correlated with the students' satisfaction. Second, the degree of participation in sports clubs influenced the physical self concept, and the frequency of participation, time, and duration showed less importance than physical self concept. The degree of participation in sports had partial influence on appearance, flexibility, physical strength, but not on health, body fat and endurance.

One of the more recent development in research of illness, both psychiatric and medical, is the formal assesment and evaluation of individuals life events (so called precipitating events). Very frequently patients are able to point out one or several incidents that have had a decisive impact on their lives, prompting the appearance of symptoms. This study was intended to examine the relationship between women psychiatric illness and its precipitating events, its life events and relating variable of personal, marital, familial and hospital history. Subjects served for the study consisted of 356 mentally disordered women, sampled from January 1978 to June 1980, using medical records and individual interview. Their age range was between 21 and 66. The actual number of cases put into the analyses was 333. Thus collected data were computerized at KIST by SPSS programming and were statistically analysed by Chi-square test. Results of the study were as follows: 1. In diagnostic distribution, 67 cases (20.1%) were diagnosed as schizophrenic disorder, 143 cases: (42.9%) as affective disorder, 118 cases (35,4%) as neurotic disorder and 5 cases (1.5%) as personality disorder and postpartum psychoses. In age distribution, 71 cases (21.3%) were ranged between 30 and 34, 64 cases (19.2%) between 35 and 39, 59 cases (17.7%) between 40 and 44, 48 cases (14.4%) between 50 and 59, 45 cases (13.5%) below 29, 40 cases (12,0%) between 45 and 49,6 cases (1.8%) over 60 years of age. Religious distribution was as follows: Protestants 58 cases (22.8%), Buddhism 39 cases (15.4%) Catholics 7 cases (6.7%) Confusianism 2 cases (0.8%) and non-religious 217 cases. Distribution of educational level was as follows: high school 162 cases (30.6%), college 81cases (24.3%), primary school 64 cases (19. 2%), illiteracy 53 cases(15.9%) and middle school 33 cases (9.9%) Occupational distribution was as follows: working women 97 cases (29.1%) and non-working, women (housewife) 236 cases (70.9%). 2. Regarding to the duration of onset, it was revealed that 66.1% among mentally disordered women with neurotic disorder had been the life events within 1 months, the affective disorder within 1 to 3 months (31.5%) and the schizophrenic disorder over 6 months (61.2%) 3. The subtypes of marital bond were as follows; the accepted bond 33.0%, the paranoid bon(14.7%, the schizoid bond 12.9%, the power-effeminate bond 12.3%, the power-anxious bond 10.8%, the excessive drinking-dependent bond 9.3%, the effeminate-dominate bond 2.7% and the others 4.2%. And female patients with accepted bond tended to show other problems except for problems with spouse, and patients with conflict habituated bond (power-effeminate, effeminate-dominate, power-anxious and excessive drinking-dependent) and devitalized bond (schizoid and paranoid) tended to show problems with spouse and physical illness as more important factors. 4. Mentally disordered women with harmonious marital relation were admitted to mental hospital by other problems except for problems with spouse, on the other hand, mentally disordered women with disharmonious marital relation, hospitalized by problems with spouse. 5. It was revealed that the important precipitating events among the mentally hospitalized women shown personal illness, increase in argument with spouse, loss of money, marital separation, troubles with parents-in-law, troubles with other family' and physical illness of family member significantly in these order. 6. Mentally disorded women between 20 and 30 shown mostly neurotic disorder and had increase in argument with spouse, loss of money, troubles with parents-in-law and trouble with other family member. Between 30 and 40, most commonly schizophrenic disorder, attacked by personal physical illness and increase in argument with spouse. Between 40 and 60, mostly affective disorder was diagnosed, developed by marital separation and business failure of husband.
