보행자는 목적지로 이동하면서 도로의 경관이나 주변건물의 외관으로부터 다양한 인상을 받으며, 따라서 목적지가 동일한 경우에 있어서도 자신의 감성적 선호에 맞는 경로를 이동한 경우와 그렇지 않은 경우에 있어서의 네비게이션 만족도는 크게 달라진다. 본 논문에서는 이와 같이 보행자의 경로선택이 네비게이션 만족도에 미치는 영향에 주목하여 보행자가 자신의 감성에 맞는 경로를 탐색하는 방법을 검토하고, 이를 적용한 네비게이션 지원시스템의 구성요건을 PDA 단말기의 인터페이스 환경을 고려하여 제안하였다. 지원시스템은 보행자로부터 경로탐색요구가 주어졌을 때 목적지에 대한 정보와 보행자 자신의 경로에 대한 감성적선호도를 고려하여 경로후보를 탐색하고 보행자-지원시스템 사이의 인터랙션을 통하여 최적경로를 결정해가는 과정을 지원한다. 경로탐색은 경로의 감성평가에 사용된 감성표현용어 사이의 관계를 퍼지론적으로 정식화 한 키워드 결합행렬에 의하여 이루어진다. 본 논문에서 제시한 지원시스템의 시뮬레이션을 통해 보행자의 감성적 선호에 따라 서로 다른 경로의 탐색이 가능하게 됨으로써 네비게이션 지원을 위한 효율적인 정보제공 수단으로서의 활용 가능성을 확인하였다.

Background: The use of dental floss along with a toothbrush is a well-known oral hygiene product that effectively removes dental plaque and reduces the risk of dental caries and periodontal disease. Despite the fact that various types of floss are being used, flossing methods based on the thread type are being taught. In addition, personal preference according to the floss types has not been investigated. In this study, individual preferences according to the floss types were investigated by experiencing various types of dental floss to both floss users and non-users. In addition, the change in intention to use dental floss in the future after flossing experience of non-users was investigated. Methods: General public participated in the individual interview survey (n=419). Subjects responded to the questionnaire after using all of the thread type, Y-type, and C-type floss. All statistics were expressed frequencies and percentages for categorical variables, and the chi-squared test was used to determine the statistical significance of associations between the variables. Results: As a result of the analysis, the preference of C-type floss was highest in both floss users and non-users. The biggest reason for not using dental floss was not knowing the necessity of flossing (36.4%). In addition, both floss users and non-users responded that C-type floss was suitable for flossing in the anterior and posterior regions. The change in the positive future intention to use dental floss after flossing experience of non-users was statistically significantly associated with age. Conclusion: This result suggests that there is a need to provide education on how to use dental floss in various forms. Based on this, it will be possible to lead a change in individual's attitude for future oral health through active and continuous flossing experience.

본 연구는 미술작품의 선호가 개인의 성격요인과 관련되는지 알아보기 위해 수행되었다. 특정 시대를 대표하는 미술사조에 대한 선호와 성격요인과의 상관에 관한 연구들이 보고되어 왔으나, 감상자에게 예술작품은 사조보다는 그림 자체가 주는 인상과 느낌이 더 중요하게 다가온다. 본 연구에서는 긍정 정서, 부정 정서를 일으키는 그림과 특정 정서를 유발하지 않는 중립적인 그림이 성격요인과 어떤 관계를 가지는지 알아보고자 하였다. 또한 자극의 친숙성이 그림 선호에 미치는 영향을 검토하였다. 참가자는 성격 5요인 질문지에 응답한 후, 제시되는 그림을 보고 그 그림을 얼마나 선호하는지 평정하였다. 선호 평정이 끝난 후, 앞서 제시된 자극들을 다시 보고 그 그림을 알고 있었는지를 평정하였다. 결과, 성격 5요인 중 신경증 점수가 높을수록 부정적 정서를 유발하는 그림을 선호하는 것으로 나타났다. 이는 슬픔, 고통과 같은 부정적 정서를 유발하는 예술에 대한 선호라는 설명하기 어려운 현상에 대해, 신경증이라는 성격요인으로의 설명가능성을 시사한다. 또한 각 정서표현 그림의 친숙점수와 선호점수 간 정적 상관이 나타나 친숙한 그림이 더 선호될 것이라는 가설이 지지되었다. 예술작품에 대한 선호에 대해서는 개인마다 다르다는 주관성과 일반적으로 널리 받아들여지는 미의 객관성이 모두 존재한다. 본 연구는 예술 선호가 갖는 주관성을 성격이라는 개인차를 통해 설명하고, 기존 연구의 사조적 분류방식에서 탈피하여 예술작품을 심리학적 관점에서 연구하였다는 점에서 의미가 있다.

In this study, six grip spans (45mm-65mm) were tested to evaluate the effects of handle grip span and user's hand size on maximum grip strength, individual finger force, and subjective ratings of comfort using a digital dynamometer with individual force sensors. Forty-six males were assigned into three hand size groups according to their hand lengths. Results showed that overall 55mm and 50mm grip spans were the most comfortable sizes and associated with the highest grip strength in the maximum grip force exertions, whereas 65mm grip span was rated as the least comfortable size as well as the lowest grip strength. In the interaction effect of grip span and hand size, small and middle hand sized participants rated the best preference and the least preference grip spans differently with large hand sized participants. With respect to the analysis of individual finger force, the middle finger force was the strongest and the highest contribution to the total finger force, followed by ring, index and little fingers. In addition, it was noted that each finger had a different optimal grip span for exerting maximum force resulting in a bowed contoured shaped handle for two-handle hand tools. Thus, the grip spans for two-handle hand tools might be designed according to the users' hand and finger anthropometrics to maximize performance and subjective perception of comfort.

The literature suggested that a small reduction in overall blood pressure can have a large effect on overall prevalence of hypertension, and therefore, the affect of taste preferences of the population on salt intake should be considered for long-term blood pressure intervention programs. The purpose of this study is to investigate the influence of salt taste preference and salt taste sensitivity on salt intake behavior as risk factors for high blood pressure. We collected information on blood pressure, diet and lifestyle behaviors, salt taste preference and salt taste sensitivity from 540 respondents from Suseo-dong, Seoul. Salt taste sensitivity was assessed by administering a 1% NaCl solution to the subject's tongue and measuring the perceived intensity on 10 level scale. Salt intake behavior was classified into 3 categories: frequency of high-sodium foods, practice of salt-reducing behavior and frequency of vegetable and fruit intake. Salt taste preference showed a significant relation to the subjects' blood pressure, i.e. subjects with a higher salt preference had higher blood pressure. Salt taste sensitivity did not show a significant relation to blood pressure. However, there was a positive correlation between salt taste preference and salt taste sensitivity. Among the 3 indicators used to measure salt intake behavior, the practice of salt-reducing behavior remained significantly correlated to blood pressure. Moreover, salt-reducing behavior and salt taste preference showed a significant correlation, i.e. people who do not like salty foods tend to practice more salt-reducing behavior, leading to reduced levels in blood pressure. In a population, a small reduction in overall blood pressure can have large effects in overall prevalence of hypertension, in contrast to clinical studies where achievement of an individual's normal blood pressure is emphasized. Therefore, taste preference of the population should be considered for long-term blood pressure intervention programs.

As aging society progresses, it is necessary to establish a housing standard that provides a healthy, safe, and convenient environment for the elderly. The objective of the study is to propose a housing space standard that is geared towards elderly living in the urban area. Three steps were taken to attain the objective. First, characteristics of housing preference, spatial usage and furniture preference of the elderly were attained through a survey. The survey was conducted targeting the respondents of the ages 60 to 79 living in three different administrative districts in Seoul. Second, the required floor space to perform individual specific behavior using anthropometric dimension of the elderly was investigated by literature review. Lastly, floor space of each space is suggested combining each area for individual specific behavior which reflects characteristics of housing preference and spatial usage. The results of the research as follows. A bedroom was planned, which includes the function of receiving guests by giving the area for the placement of a sofa. The space for the use of dinning table for two person was planned in the kitchen and The space for the behavior of showering on a chair was planned in a bathroom. Lastly, the space for the behavior of taking off shoes on a chair was considered in the entrance area. Consequently, $35.4m^2$ is suggested as the necessary floor space for the elderly housing considering the characteristics of the elderly in urban area. However, because of space composition and space for accessibility, the additional space should be considered to plan the elderly housing.

Since Korea has already become the 'aging society' and is expected to become the 'aged society' by 2019, development of the facilities and dedicated housing for the senior citizens have become the key issues. The growing population of the senior citizens, changed in the social structure, family type, and the way of living brings a moment to consider the various aspects to support the senior citizens. Now the situation in Korea requires development of congregate housing as a type of residential units for elder who can live at home with some help. Therefore, the purpose of this research was to analyze preference tendency on the interior finishing materials and colors of the congregate housing for the senior citizens who are healthy enough not needing the nursing home. For this research, the preference of 500 Korean pre-senior citizens on the interior finishing materials and colors of congregate housing for the seniors was investigated. The collected data was processed using SPSS 10.0 for Windows regarding frequency, percentage, average, Chi-squared test with cross tabulation. The results are as follows: First, about $60\%$ of the respondents preferred Korean traditional interior image for individual units, and modern interior image for common areas. Second, the respondents preferred wood flooring and wallpaper interior finishing. Third, the respondents Preferred Y, YR color for individual units, and N color for common areas and very pale tone for all spaces. Fourth, the respondents preferred luxury finishing to living room in the all spaces.
