The purpose of the study is to examine the demographic characteristics and socio-psychological factors affecting willingness to take health foods among elderly, which is to get the basic materials of educational program for helping their desirable intake of healthy food. The data were collected from 1,032 elderly subjects and analyzed by SPSS Windows Version 12.0. About forty-one percent of the respondents were taking health foods in the period of survey. The main reason of taking health foods was to maintain and improve their health. The elderly subjects were classified into three groups: (1) a group having willingness to take healthy food, (2) a group having unwillingness to take healthy food, and (3) a group having a wait-and-see attitude. According to the results of chi-square and analysis of one-way variance, there were significant differences among three groups in the variables of 'sex', 'age', 'educational level', 'marriage status', 'monthly allowance', 'eating habit', 'concerns about health', 'self -evaluation of health condition', 'self-evaluation of health condition compared to the same age', 'concerns about health foods', and 'awareness of health foods'. In addition, the result of multinomial logistic regression analysis showed that the factors affecting willingness to take health foods in the future are 'age', 'concerns about health', 'self-evaluation of health condition compared to the same age', 'awareness of health foods', and 'intake of health foods in the period of survey'.

Certain complex forces are existing at the other side of a canvas. These are visual arrangements and within the arrangement, even the simple combination of dots and lines create more than visual patterns. No matter what form that visual art has taken, it is performed in a certain space and it is constucted with various visual elements. For effective communication, visual elements must form a stable sturcture by extablishing organic relationship among each other. These requires an understanding of the human visual characteristics and psychonology, because human sight senses the same biological and psychological visual elements differently in its force and weight, according to the position within a given space. Although the structure which controls such force and weight exists within a peice of work, it is a internal plan of the work that actually controls the communication through a man\ulcorner psychological reactions towards the horizontal and virtical structures within it. Moreover it is a visual statement that effectively expresses a theme or a message. This thesis has studied visual structures through the analysis of art pieces regarding of these kind of a visual picture plane, characteristics of a picture plane formed by a structure of force existing on the other side of the picture and the theory of visual balance. In addition, the aim of this study is to help designers who deals with visual image works to understand the visual structures and psychological recognitions and to apply these picture plane compositions at their real work by recognizing the psychological power within the construction elements.

One of main issues in watermarking is to resolve the strength of watermark for solving the problem of trade-off between fidelity and robustness of watermarking. In the previous research, the strength of watermark has been resolved fixed value generally without considering local image characteristics such as image brightness, contrast, and edge. This paper proposes a new model to predict the strength of watermark considering local image characteristics such as image brightness, contrast, and edge for digital wavelet transform(DWT)-based image watermarking. For the study, psychological experiment was fulfilled to measure the human image perception and regression analysis showed the proposed model was statistically significant at the level of ${\alpha}\;=\;0.01$. Also the model is practically validated on fidelity and robustness of watermarking.

The study explores the effects of recording and viewing distances in stereoscopic 3D on presence, perceptual characteristics, and negative experiences. Groups of 20 participants were randomly assigned to each of the three viewing distances, and all participants were exposed to five versions of the stereoscopic 3D music video that differs in recording distance. The results showed that first, viewers felt a higher experience of presence and had a better perception of objects positioned near the cameras. Second, viewers felt a greater perception of screen transmission as the viewing distance increased. Finally, viewers felt a greater negative experiences due to the joint effects of recording and viewing distance. As investigating the influence of stereoscopic 3D content and viewing environments on psychological factors, the study expects to provide a guideline of human factors in 3D.

The strategy that using data collection from Netflix uses for its services is different from traditional human interaction and the communication, and it is represented by the systematic algorithm that rooted from intelligent information system based on the human interaction and communication. These characteristics allowed the study to reflect the influence of 'Asset specificity' which affects the continuous consumption of the media services of Netflix users through economic psychological analysis based on transactional cost economics. The result from the survey on actual Netflix users, three types of specificity (Space specificity, time specificity, relational specificity) reduced perceived searching cost whereas perceived instrumentality has increased, eventually reinforces the commitment to the service. This implies that the service characteristics of Netflix, trying to communicate with the individuals based on intelligent information system are distinct from the existing platform services and it gives the significance of work very effective for user's continuous consumption of the media services.

This study identifies the effects of the characteristics of an online shopping cart based on the theory of psychological ownership. This study created experimental stimuli similar to the actual fashion website in order to derive the exact emotional and behavioral responses of participants. To test the hypotheses, four experimental groups of 2 (personalization: high / low) × 2 (accessibility: high / low) were formed with between-subject design. We selected 201 women in 20-30s as participants and they responded to an online survey after experiencing website stimuli. The collected data were analyzed using SPSS 25.0 and SPSS PROCESS Macro program. The results show that the effects of personalization of an online shopping cart on the purchase intention of the fashion product in the cart is significant; in addition, the main effect of personalization of cart on consumer's psychological ownership was confirmed. It was also found that the path of personalization of the online shopping cart to purchase intention through psychological ownership was significant. The findings of this study contributes to the extension of online shopping cart research and provide suggestions to recognize the important role of psychological ownership in increasing the purchase conversion rate.

The main purpose of this study was to examine the mediating roles of mothers' psychological well-being and support/control in the relationship between maternal child-related stress and adolescents' school adjustment. Participants were 389 3rd grade middle school students and their mothers. Mothers completed questionnaires about child-related stress and psychological well-being. Adolescents completed scales of maternal controlling/supportive parenting and school adjustment. Results indicated that a direct effect of mothers' child-related stress on adolescents' school adjustment was not significant. However, mothers' psychological well-being and support/control mediated the relations between child-related stress and adolescents' school adjustment. A higher level of child-related stress in mothers was associated with a lower level of psychological well-being, followed by a lower level of adolescents' school adjustment. Mothers who reported a higher level of child-related stress tended to be less supportive and more controlling, which led to a lower level of school adjustment. These findings suggest the need for considering both maternal characteristics and parenting in explaining adolescents' school adjustment.

It is necessary to evaluate HMI inaspects of human factors in the design stage of MMIS(man machine interface system) and feedback the result of evaluation because operators performance is mainly influenced by the HMI. Therefore, the MMIS design should be reflected the operators psychological, behavioral and physiological characteristics in the interaction with human machine interface(HMI) in order to improve the safety and availability of the MMIS of a nuclear power plant(NPP) by reduction of human error. The development of human factors experimental evaluation techniques and integrated test facility(ITF) for the human factors evaluation become an important research field to resolve hi,am factors issues on the design of an advanced control room(ACR). We developed am ITF, which is aimed to experiment with the design of the ACR and the human machine interaction as it relates to the control of NPP. This paper presents the development of an ITF that consists of three rooms such as main test room(MTR), supporting test room(STR) and experiment control room(ECR). And, the ITF has a various facilities such as a human machine simulator(HMS), experimental measurement systems and data analysis and experiment evaluation supporting system(DAEXESS). The HMS consists of full-scope simulation model of Korean standard NPP and advanced HMI based on visual display nits (VDUS) such as touch color CRT, large scale display panel(LSDP), flat panel display unit and so on.

In the design guideline for the existing elderly house, the guideline related to kitchen is very important in the secure and functional aspect. In spite of importace, the present elderly house's Kitchen plan is being designed based on foreign universal design guideline or common housing form instead of considering physical social and psychological qualities of the korean elderly. Therefore, In this study based on the guideline of the previous studies related to domestic elderly house and kitchen plan for elderly house, we found physical social and psychological qualities of the korean elderly. Acooording to these characteristics we suggested guideline on kitchen plan for Elderly House. Those suggested here will be applied to design guidelines of elderly housing on kitchen plan in future.
