The purpose of this study was to evaluate performance and subjective satisfaction of mobile phone's interface elements considering the elderly users. First, mobile phone's interface elements were outlined recent foreign and domestic studies. Then, final three mobile phone's interface elements were determined by expert rating, AHP analysis, and questionnaire analysis. Objective and subjective measures were then used to determine the effects of several specific design parameters and aging differences on performance of mobile phones. In this experiment, 38 subjects and 4 independent variables were used to measure task completion time and user's subjective satisfaction. The statistical analyses indicated significant aging differences between older people and younger people in terms of keypad type and bell sound level in performance. Significant aging differences were also found for user subjective satisfaction. It is suggested that some major results from this study be used to develop mobile phone design guidelines that are more usable and accessible for most users, particularly for older users.

Despite of many supportive research to the usefulness of slide evaluation on environment of outdoor lighting, study method of using slides have provoked many discussions of its manifestation of reality of field conditions. This study aims to compare the results of slide survey with that of field survey. Distant view and short range view of nightscape of Seoul were selected. Field measurement of luminance and chromaticity were conducted and questionnaire survey were conducted. Frequency analysis, T-test, factor analysis were conducted. Results shows that distant view and short range view of field survey have better visual atmosphere than slide survey. In addition, slide survey on distant view shows lowest values. Difference between field survey and slide survey on distant view is much bigger than the results of short range view.

This study proposes a method to measure mental fatigue using speech technology, which has not been used in previous research and is easier than existing complex and difficult methods. It aims at establishing a relationship between the human voice and mental fatigue based on experiments to measure the influence of mental fatigue on the human voice. Two monotonous tasks of simple calculation such as finding the sum of three one digit numbers were used to measure the feeling of monotony and two sets of subjective questionnaires were used to measure mental fatigue. While thirty subjects perform the experiment, responses to the questionnaire and speech data were collected. Speech features related to speech source and the vocal tract filter were extracted from the speech data. According to the results, speech parameters deeply related to mental fatigue are a mean and standard deviation of fundamental frequency, jitter, and shimmer. This study shows that speech technology is a useful method for measuring mental fatigue.

This study empirically evaluated performance and preference of Hangul entry methods of five mobile phones through questionnaire and experiments. The questionnaire study revealed that 67% of respondents have been using SMS(short message service) more than six times a day, and that Hangul entry method is the most inconvenient thing when inputting Hangul characters. An experiment was conducted for assessing five Hangul entry methods in view of performance of entry time and errors, and subjective measures of satisfaction and preference. The results showed that Hangul entry method significantly affect objective performances as well as subjective measures at α=0.05 or 0.01. This study, in which real mobile phones were used, presented contrary result in terms of Hangul entry time, compared to the existing studies based on the conceptual models of Fitts' law or Hick-Hyman law.

Methods : A questionnaire study accompanied with the evaluation of working environment was performed with 42 VDT users from banking operations. Results : As a results of analysis with data colleted by newly developed questionnaire, VDT syndrome included five factors named as eye-related component, and psychological component. general body discomfort component. musculoskeletal component, and skin-related component. The scores of eye-related symptoms was 15.17, scores of psychological symptoms was 7.36, scores of general body discomfort symptoms was 10.52, scores of musculoskeletal symptoms was 9.38, scores of skin-related symptoms was 3.67, and total scores was 46.10. Scores of 2.05 eye fatigue in the level of eye-related symptoms were higher significantly. Scores 50.52 of female was statistically higher than scores 41.67 of male. Conclusions : The subjective symptoms of VDT syndrome scores was significantly associated with gender and age.

사용자의 감성을 측정하기 위한 심리적 측정방법 중에서 사용자가 느끼는 감성을 형용사와 같은 어휘를 통해 간접적으로 측정하는 방법, 즉 감성어휘를 추출하여 사용자의 감성을 측정하는 방법이 가장 보편화되어 있는 방법이다. 본 연구의 선행연구에서는 사용자가 제품을 사용하는 도중에 유발되는 인간의 감성 변화를 나타낼 수 있는 감성어휘들과 대표감성들을 추출하여 제품을 사용하는 도중에 표출되는 사용자의 감성을 측정하기에 적합한 주관적 평가스케일을 도출하였다. 사용자의 감성을 측정하기 위한 심리적 측정방법에는 감성어휘를 이용한 체크리스트 외에도 자기-보고 질문지형 스케일도 널리 사용되고 있다. 따라서 본 연구에서는 선행연구를 통해 도출한 주관적 평가스케일을 보다 더 효과적으로 활용하기 위하여 자기-보고 질문지형 스케일을 제안하였다. 또한 개발한 자기-보고 질문지형 척도의 Cronbach's ${\alpha}$ 계수 분석을 통해 신뢰도를 확인할 수 있었다. 따라서 본 연구에서 제시한 자기-보고 질문지형 척도는 제품을 사용하면서 자연스럽게 표출되는 사용자의 감성을 효과적으로 측정하기 위한 척도로 활용할 수 있을 것이다.

본 연구는 일반 성인을 대상으로 고통 감내력이 주관적 안녕감에 미치는 영향을 검증하고, 고통 감내력과 주관적 안녕감의 관계에서 경험회피의 매개효과를 알아보고자 하였다. 이를 위해 2015년 10월 21일부터 24일까지 전국의 일반 성인 285명을 대상으로 온라인 설문조사를 실시하였다. 고통 감내력 부족 척도, 주관적 안녕감 척도, 수용 행동 질문지로 설문지를 구성하였고, 온라인 조사 전문업체에 의뢰하여 설문지를 배포 및 회수하였다. 수집한 자료는 구조방정식 모형을 통하여 분석하였다. 분석결과, 고통 감내력은 주관적 안녕감과 정적 상관을 보였고, 경험회피와는 부적 상관을 보였으며, 주관적 안녕감과 경험회피는 부적 상관을 나타냈다. 또한 고통 감내력과 주관적 안녕감의 관계에서 경험회피의 매개효과를 검증한 결과, 경험회피는 유의한 수준에서 고통 감내력과 주관적 안녕감의 관계를 부분 매개하는 것으로 나타났다. 마지막으로 간접효과의 검증을 위하여 편향수정 Bootstrapping을 실시한 결과, 고통 감내력이 경험회피를 거쳐 주관적 안녕감으로 가는 매개효과가 통계적으로 유의한 것으로 나타났다. 즉, 일반인의 고통 감내력이 주관적 안녕감에 직접적인 영향을 미치면서 동시에 경험회피를 통해 간접적으로도 영향을 미치는 것을 알 수 있다. 마지막으로 본 연구의 의의, 제한점 및 추후 연구를 위한 고려사항에 대해 논하였다.

The purpose of this study was to measure the causal relationships between past consumption, health belief, subjective, attitude, intention and purchase of organic foods. Total 326 copies of questionnaire were completed. The structural equation model was used to measure the causal effect among constructs. The results demonstrated that the confirmatory factor analysis model provided a good model fit. The proposed model yielded a significantly better fit to the data than the baseline model and the extended model. The effects of past consumption, health belief and subjective norm on attitude and intention were statistically significant. The effects of attitude on intention and behavior to purchase organic food were statistically significant. As expected, health belief and subjective had significant effects on behavior to purchase organic foods. Moreover, past consumption, health belief and subjective norm had indirect influences on intention through mediated variables. Based on the empirical results and findings, some suggestions are provided to the institutions concerned so as to facilitate this organic sector's on-going expansion in the food industry.
