This paper presents a factor-analysis based questionnaire categorization method to improve the reliability of the evaluation of working conditions without influencing the completeness of the questionnaire both in Taiwanese and Chinese construction enterprises for structural engineering applications. The proposed approach springs from the AI application and expert systems in structural engineering. Questions with a similar response pattern are grouped into or categorized as one factor. Questions that form a single factor usually have higher reliability than the entire questionnaire, especially in the case when the questionnaire is complex and inconsistent. By classifying questions based on the meanings of the words used in them and the responded scores, reliability could be increased. The principle for classification was that 90% of the questions in the same classified group must satisfy the proposed classification rule and consequently the lowest one was 92%. The results show that the question classification method could improve the reliability of the questionnaires for at least 0.7. Compared to the question deletion method using SPSS, 75% of the questions left were verified the same as the results obtained by applying the classification method.

본 연구는 시민들이 일상생활에서 마주하는 문제들을 그 탐색행위의 특성에 기반하여 범주화함으로써 시민들의 정보문제 해결에 실질적인 도움이 되는 정보 서비스를 탐색하기 위하여 실시되었다. 우선, 심층면담을 통해 시민들이 일상생활에서 직면한 문제에 대한 핵심 키워드를 추출하였다. 추출된 키워드는 정보탐색행위의 특성에 따라 6가지 문제 영역(취미, 법률, 시사, 교육, 건강, 경제)으로 범주화하였으며, 범주화 결과의 타당성을 위해 설문을 통해 각 범주의 선호 정보원의 차이에 대하여 통계 분석을 실시하였다. 그 결과, 문제 영역 간에 선호 정보원의 차이가 검증되었으며, 이를 통해 취미, 법률, 시사, 교육, 건강, 경제로 구분한 6가지 문제 영역 구분이 어느 정도 타당성을 가지고 있는 것으로 나타났다. 본 연구는 이러한 결과를 기반으로 기존의 주제별 정보 서비스에 대한 재검토 필요성을 제기하며, 문제 중심 정보 서비스로의 전환 가능성을 논의하였다.

Objectives: Although medical typologies based on indigenous biopsychological ideas have been described, their integrity has been questioned due to its theory-driven nature in categorization. Therefore, studies on the Sasang typology, a temperament-based traditional Korean medicine, are needed to examine whether it is possible to classify types of specific biopsychological profiles using data-driven analysis. Methods: Psychological measures of the Eastern Sasang Personality Questionnaire (SPQ) and Western NEO-Personality Inventory (NEO-PI) along with physical measures and Sasang types were acquired from 2,049 participants. Latent groups based on the SPQ and NEO-PI subscale scores were extracted using Latent Profile Analysis. Their psychosomatic features were then compared with those of Sasang types. Results: Three SPQ-based latent groups showed distinctive psychological and physical features consistent with those of Sasang types. However, four NEOPI-based latent groups presented only psychological features. Furthermore, SPQ-High and SPQ-Low latent groups demonstrated similar psychosomatic profiles to those of So-Yang and So-Eum Sasang types, respectively. Conclusions: This study illustrates that biopsychological profiles of Sasang types are supported by psychosomatic features of latent groups based on SPQ of Eastern psychology, signifying that the categorization of Sasang typology have acceptable validity and reliability.

The purpose of this study was to investigation the importance and categorization of task elements of school food service dietician and to provide the useful data for standard model of the dietician′s tasks of school foodservice. This study was conducted in school food services nationwide in method of written questionnaire. The questionnaires were mailed to the dieticians of 3 type school foodservice system-conventional, commissary, joint management. Of the 660 schools that participated in this study, the responses from 212 conventional system and 212 commissary system and 200 joint management system were selected for analysis. Statistical analysis was performed with SAS/Win 6.12 package program for descriptive analysis, T-test, ANOVA, factor analysis using. The main results of this study can be summarized as follows Importance level was more than 4 score out of 5 scale in most of the task elements. The result was indicative of the appropriateness of definition of the 61 task elements. Of 61 task elements, importance level on ′nutrition education′ and on ′evaluation of foodservice operation management′ indicated the most significant difference between present and ideal situation. Through factor analysis, 61 task elements were regrouped into 7 dimensions; "Duty dimension of cooking and distribution management", "Duty dimension of cost management", "Duty dimension of raw material management", "Duty dimension of education management", "Duty dimension of menu management", "Duty dimension of record keeping of foodservice", "Duty dimension of general management (others)".

The objective of this study was to establish Facility classification for military barracks among military facilities. The military barracks are the place where soldiers spend most of their time. Thus, a new type of space in military barracks is required to improve the quality of life of the soldiers and make the military more advanced for national defense. The research method was to derive problems through a survey of the previous literature and case studies and to select target places in the Army, Navy, Air Force, and Marine based on the derived problems. An improvement scheme was proposed by developing criteria for military barracks spaces through a questionnaire survey. The following results were obtained: Facility classification inside of national defense military facility standard should be reorganized. The alternative plan is demanded for some camp which has no need about setting up the office facility. And the study of reasonable facility area after improvementing facility categorization is required.

With international attention to the rural landscape, there have been landscape management and conservation efforts. Because it contains characteristics of rural area, rural landscape has been recognized as an important component of rurality. With rural amenity resources survey projects launched since 2005, rural landscape categorization and evaluation such as resource value, use value, beauty, originality, traditionality, maintenance are performed by expert questionnaire survey and 100 rural amenity resources are selected. In this study, we performed fractal analysis for developing evaluation system of the rural landscape photographs. In evaluating processes, main and surrounding landscape are separated and fractal indexes are calculated and analyzed with beauty value scoured by experts. Results show that beauty value is not significantly related with fractal index but differences of main and surrounding landscape fractal index.

First, in order to improve selecting method of quality characteristic level desired by customers, S/N(Signal-to-Noise) ratio of Taguchi in larger-the-better characteristics was applied. Second, the Matrix classification standard of ACE(Attribute Categorization Evaluation) is presented using KANO model on difference analysis of importance and satisfaction through questionnaire from customers. This is for reflecting the diverse EC which customers want in EC quality sufficiently. Also, establishing sales point will be helpful in business strategy through presenting types that are able to decide planning quality. Third, the important measure of EC about correlation among quality characteristics and a new weight of EC are calculated depending on importance of EC and the weight of customer attribute and materials of relationship matrix through correlation matrix analysis.

웹 2.0환경에 중심이 되고 있는 블로그 사용자들에게 있어 웹 브라우저에서 실행될 수 있는 위젯(widget)은 자신을 표현하고, 블로그의 가치를 돋보이게 하는 도구이다. 위젯은 윈도우(Window)와 가젯(Gadget)의 합성어로 응용 프로그램을 동작시키고 결과를 화면에 표시하는 그래픽 사용자 인터페이스(GUI) 도구의 일종으로써 사용자가 원하는 서비스를 받아 볼 수 있는 기능성 프로그램이다. 또한 운영 제체(OS)나, 웹, 모바일에서 사용자에게 정보 전달 및 사용 편리성과 효율성을 제공하고 있다. 그러나 현재 위젯은 정보 전달이나 현상 표현에 초점을 마주고 있어, 사용자들이 원하는 재미를 충족시켜주지 못하고 있다. 이 연구는 웹 2.0 환경에서 사용자가 많이 사용하고 있는 위젯의 재미와 흥미를 느끼는 요소가 무엇인지를 파악하고, 위젯별 재미 요소를 분류 하고자 하는 연구이다. 위젯에서의 재미 요소에 대해 아직까지 정의된 것이 없기 때문에 제품 디자인과 게임에서의 재미 요소를 분류 및 분석을 통해 추출 하였고 추출된 결과를 사용자의 감성 상태를 대표하는 감성 어휘와 매핑을 통해 파악하였다. 그리고 위젯별 재미 요소를 알아내기 위해 블로그 사용자를 대상으로 온라인 설문을 실시하였다. 위젯 선정은 사용자가 많이 이용하고 있는 국내 위젯과 일본 위젯으로 선택하였고 5점 척도를 이용해 위젯별 재미 요소를 분류하였다. 이 결과를 바탕으로 사용자가 선호하는 재미 요소를 파악할 수 있다.
