The purpose of the study was to develop an internet nutritional counseling program using an expert system to assist obese people to lose weight through behavior modification. The internet counseling program for weight loss was developed by the accumulation of knowledge dealing with eating habits and exercising behaviors in expert system tool, Knowledge Engineering Agent (KEA) by a dietitian without any help of computer expert. To accumulate knowledge into KEA, survey was performed in 150 obese people, dietitians reviewed and consulted each survey case, and the consulted contents were learned and accumulated into KEA. Survey questionnaire was the same as that of the internet consulting program, and it included general characteristics, dietary habits, lifestyle, and exercise patterns related to obesity. Also, the dietitian selected proper factors inferred from the survey questionnaire of each case, and added the conclusions for them. Conclusions were made for helping clients to correct bad eating behaviors and accumulate good behaviors to lose weight. Counseling was divided into two parts; a two-week part and a daily part. Two-week counseling was performed based on 4 step questionnaires, and daily counseling was done for daily food consumption and physical activity. When clients answered survey questionnaires in a counseling internet program, the recommendations on how to eat, to exercise and to deal with stress in a real time for each case, was given. In conclusion, a counseling internet program for weight reduction can be used to give advices how to deal with obesity in a man-to-man way in a real time using KEA where nutritional knowledge based on behavior modification for weight loss was accumulated.

Subjective evaluation has always been regarded as a branch of social science research. Hence, in scientific and especially engineering points of view, its development is always taken for granted despite the importance of its effects on the design and development decisions. In the past, at least two automotive seat survey questionnaires have been developed with high statistical validity and reliability. Nonetheless, both were not local while subjective perception very much depends on demographic background factors. It is felt that since vehicle seat comfort is an important aspect in a seat design, a local sense should be put into the survey that is used as the subjective tool. The proposed vehicle seat discomfort survey questionnaire was developed in dual languages; English and Malay. Malay language is the national language of Malaysia, where the survey was tested. Beside inputs from literatures, key informant interviews helped in establishing the appropriate terms used as survey items. Three experimental runs on two different seats by 22 paid subjects showed that the developed questionnaire is reliable and valid. Furthermore, criterion validity analysis on the survey and previously developed survey showed significant correlation at 0.01 significance level.

This paper investigated the influence of foreign words, otherwise known as loan words, on global communication abilities of university students from two non English-speaking countries: Korea and Japan. To survey the understanding and usage of foreign words which are from English language and used frequently in daily conversation, questionnaires were administered to Korean and Japanese university students majoring in engineering who shared similar linguistic backgrounds. The results were analyzed from global communication viewpoint. Based on the results, methods for improving global communication skills in engineering education were proposed.

Since recent development of questionnaire for Sasang constitution, many researches have followed it to verify statistical significancy. However, a few problems about validity of some questionnaires were discovered later on due to the lack of researches about it. Firstly, some questionnaires have different meaning from that of the original Dongyi Suse Bowon. Secondly, belief on statistical significancy sometimes misleads the questions for a certain Sasang constitution to be used for a different Sasang constitution. Thirdly, profound concepts of original Dongyi Suse Bowon are sometimes abandoned or ignored in the excuse of low statistical significancy. Fourthly, it is still difficult to identify Sasang constitution of Taeyangin due to lack of population, sample, and questions. The purpose of this thesis is to minimize the problems related with interpretation and fitness of the questionnaires. The author developed a questionnaire of 48 questions and surveyed with it over 200 patients who visited Jeon-ju Woosuk hospital. This research resulted in a bit of resolution of the problems through statistical comparison between the survey and clinical analysis.

Purpose: This study aims to analyze why surveys of a single set of customer requirement result in different Kano analyses depending on the survey questionnaire designs. Methods: This study singled out 14 common features from four different questionnaires of two studies of Smart Car features and analyzed them using the Kano model. Several methods and devices were used: Group Comparison and Timko Index were applied; Kano Distribution Index, Timko Dispersion and Kano Conformity were newly introduced for the quantitative analysis; Correlations between Timko indices from different Kano questionnaires were conducted; Heuristic Splitting technic for reinforcing attribute categorization is introduced. Results: Correlation Coefficient proved strong positive relations among the three questionnaires, whose agreement degree of the resulting Kano attributes showed less than 10% when Indifferent was ignored. Heuristic Splitting on Timko charts enhanced the degree of the resulting Kano attributes up to 80%. Conclusion: Among the questionnaires the representation of customer requirements tends to move by parallel shifts on the Timko chart maintaining their relative locations. Heuristic Splitting suggests a rational solution to the interpretation of those inexplicable attribute categories resulting from traditional Kano methods.

2011년 3월 11일 발생한 일본 후쿠시마 원전 사고 1주년을 계기로 한국 국민의 방사선 인식도를 조사하고자 하였다. 연구 방법론적 설계는 양적 조사로 하고, 빈도 분석을 하였다. 분석 대상은 전국에서 무작위로 추출한 일반인으로부터 수거한 설문 응답지 2754부이다. 연구 도구는 설문지이며, 직접 배포한 뒤 수거하였다. 설문은 40문항으로 구성하였으며, 하위영역별 크론바하 알파(Cronbach's ${\alpha}$) 계수는 '방사선의 자아인식' 0.620, '방사선의 위험' 0.830, '방사선의 편익' 0.781, '방사선의 관리' 0.685, '방사선의 정보원' 0.831, '후쿠시마 사고의 영향 정도' 0.763으로 모두 높게 나타났다. 설문 분석 결과 응답자의 방사선 개념에 대한 지식은 100점 만점 환산 평균 69.5점이며, 이는 자신들이 '방사선에 대해 잘 알고 있다'고 응답한 비율 53.7%, '보통 알고 있다'는 응답이 37.4%인 것과는 상당히 다른 결과다. '방사선이 위험하다'고 느끼는 중요 원인 중 하나는 '방사선에 노출되면 지금은 아니더라도 다음 세대에 문제가 생길 수 있기 때문'(66.1%)으로 분석됐다. 방사선에 대한 정부 발표를 믿지 못하는 응답자가 41%에 이르러 정부에 대한 불신이 높았다. 후쿠시마 원전 사고 때문에 원전을 운영하지 말아야 한다는 쪽으로 생각을 바꾼 응답자도 39.5%나 됐다. 본 연구는 후쿠시마 원전 사고 이후 방사선에 대한 한국 국민의 인식을 처음 조사한 것으로 그 의의가 크다. 향후 방사선에 대한 정부의 정책 수립에도 크게 기여할 것으로 기대된다.

The study examines direct and indirect impacts of organizational commitment on employee motivation through two mediating factors - opportunistic behavior and knowledge sharing - in Vietnamese enterprises. The samples were selected by the non-probability sampling method followed convenient sampling, relatively stratified by localities in Vietnam. The sample size was 636 employees in Vietnamese enterprises. The number of collected online questionnaires was 379, while the number of valid questionnaires was 329. In the direct survey, the number of distributed questionnaires was 750, while the number of collected questionnaires was 421 and the number of valid questionnaires was 307. The total number of valid questionnaires used for analysis was 636. The study used quantitative methods with structural equation modeling analysis. The results indicate that among the components of organizational commitment, normative commitment has both direct and indirect impacts on employee motivation through two mediating factors: opportunistic behavior and knowledge sharing. Meanwhile, affective commitment has only an indirect impact on employee motivation through these mediating factors. Continuance commitment has both direct and indirect impacts; however, it has only an indirect impact on employee motivation through opportunistic behavior. In addition, the results show opportunistic behavior has a negative impact on the knowledge sharing of employees in enterprises.
