This is a user experience study of factors that should be considered in designing home appliances experience service. Untact services are emerging, but the development of home appliances sector is in early stage. Based on the six factors of Stephen P. Anderson's Creating Pleasurable Interface Model, this study conducted surveys, 1:1 in-depth interviews, and participation observations to measure and analyze user experience. In this study, I compared 4060s and 2030s's user experience in that the untact services raise the digital alienation among middle-senior-aged. As a result, there were significant differences between the two, including the opposite satisfaction in terms of reliable, usable and pleasurable factors. I hope that this study will be of strategic help in designing future home appliance experience services.

Aspects of health food intake were investigated by conducting a questionnaire survey with over 480 of adults in Taejon and the data were analyzed by $\chi$$^2$-test, t-test and ANOVA, using an SAS program. Eighty two percent of the subjects had taken some kind of health food. The health foods they took frequently were, for example, health drinks, green tea, ginseng products, dietary fiber drinks, honey, general tea, vitamin B, vitamin C, and tonic medicines. The main reason for taking health foods was recovery from fatigue and the frequency of taking health foods was one time per day. Most of the subjects took health foods without knowledge of their components or effects. When they health foods with a perceived knowledge of their components and effects, they responded that the health foods were very helpful for them. Twenty percent of subjects experienced side effects, such as diarrhea, stomachache, headache, nettle rash, and stomach cramps. Information on health foods was obtained mainly from friends or family. The user group showed higher intention to continue health food intake than non users(p < 0.001). Health foods were taken without any knowledge about them. Health food intake was significantly correlated with consideration of disease, suffering or disease, medical examination, and self-perceived health status, but not with food habits and health food knowledge. As for the results from the adults consumption pattern of health food, an education program should be developed to choose proper health foods according to the consumers dietary life and health conditions. Also a proper guide line should be established to be chosen the authorized health foods.

Recently orthodontics in elderly people is continually increasing due to aging of the society arising from decrease of birth rate as well as death rate. As the elderly population grows, needs for oral health care increases, and elderly patients with poor teeth alignment need more attention with orthodontic treatment. Our study analyzes various treatment protocols for different cases of aged orthodontic patients, and following are considerations in orthodontic treatment of elderly patients. 1. Periodontal treatment should be preceded before orthodontic treatment. 2. Periodontal condition should be considered when selecting teeth for extraction 3. In dealing with the residual prosthesis, condition of prosthesis, anchorage availability, and need for size reduction, patient seconomic status should be taken into consideration. 4. Fixed retainers are recommended for retention.

Cutaneous angiosarcomas are uncommon malignancies which account about 1$\%$ of sarcomas. They are found most commonly in the head and neck regions, frequently on the scalp. Although preferred treatment has been combined surgery and postoperative radiation therapy, the extensiveness and multiplicity of the lesions set limits to such an approach and the patient is often referred for radiotherapy without surgery. As the entire scalp usually needs to be treated, radiation therapy is a challenging problem to radiation oncology staffs. We report a case of angiosarcoma of the scalp, which was treated successfully by radiation therapy with a simple and repeatable method using mixed Photon and electron beam technique. Using a bolus to increase the surface dose of the scalp and to minimize dose to the normal tissues of the brain desirable but difficult technically to be well conformed to the three dimensional curved surface such as vertex of the head. A helmet made of thermoplastics filled with paraffin was elaborated and used for the treatment, resulting of the relatively uniform surface doses along the several points measured on the scalp, the difference among the points not exceeding 7$\%$ of the prescribed dose by TLD readings.

The purposes of this study is examining a wearing tendency of a progressive multifocal lens. We measured refractive error values using subjective and objective refraction method with subjects in 40-65 ages. Also, we investigated and analyzed distribution of addition power and wearing tendency of progressive multifocal lens. Detected addition powers were ranged of +0.75D - +3.00D. In case of average addition, they were detected with +1.18D in 40's, +1.55D - +1.97D in 50's and +2.38D in above 61's age. The distributions of visual ability at a distant were measured that the hyperopia and hyperopic astigmatism 43%, the myopia and myopic astigmatism characteristic astigmatism 7% appeared highly with 36%. The male who uses the interior aspect multi focal lens with the short-range work were appeared the male 20%, the woman 19%.

This study attempts to create a longitudinal dataset by linking tdata on the identical individuals across the monthly sample household management lists of the Economically Active Population Survey(EAPS) and the Household Income and Expenditure Survey(HIES). Using the data constructed through such process, the study also tryies to analyze the duration of longitudinal responses and the characteristics of nonrespondents. Between 1998 and 2002, longitudinal response rates had declined to 46% of total EAPS and 34% of total HIES. The fact that nonresponse was not a random phenomenon leads to concerns about the representativeness of the remaining sample. Using Cox's proportional hazard model the study revealed that the duration of longitudinal responses is affected by the ownership of house and the age of the respondent.

Main purpose of this study is to analyze determinants of household debt among middle and old individuals aged between 32 and 76 that include Korean baby-boomers(born between 1955 and 1963), using a HAPC (Hierarchical Age-Period-Cohort) model and Korean Welfare Panel Study 2006-2016. This study includes 86,056 individuals. Research findings indicate that aging and period effects have statistically significant relationships with household debt levels, however, cohort effects including a baby-boomer generation do not. While household debt increases by 3,530,000 Korean won as age increases by one year, the rate of increase in household debt reduces as individual ages. In addition, employment and health status at the individual level have significant effects on household debt levels. The unemployed are more likely than the employed to have high household debt levels while unhealthy people tend than healthy people to have high household debt levels.

As for comics and animation, the specific gravity came to become still larger in all the art fields together with the importance in various image media now which is useful and goes the time of the 21st century new media. Especially the demand of users to the vision culture which develops day by day, Sensitivity Engineering Department is trying to realize the necessity for a sensitivity design acutely together. The influence of the comics which have toxicity most also in Japanese culture in a geographical position like South Korea on it, and animation is the actual condition in the reason which has reached from youth universally to the layer for years, to be inquired systematic to a Korean comics language. This reserch was conducted as we thought sufficient study on various situations are required, and among them, for the reserch of expressions of cartoons's characters, we've divided the expressions of characters that comes out in Japanese cartoons into catagories of "happiness, anger, sadness, pleasure" and "fear, astonishment and dislike" and based on these catagories, we've drawn out the minimum elements to express emotions in cartoon and prepared image-map by relating them with languages that express emotions of people and based on this, we've made a calculating tools on how our readers would read the expression languages. Samples of Japanese cartoons of which we've chosen for the purpose of drawing out the elements of expressions were limited to only published cartoons and we've made a foot steps for expression analysis of animation characters in the future.
