Nowadays, family support on the aged person is prioritized than the others. However, number of aged person is growing, and family, which is used to protect the aged, becomes nuclear through industrialization. In addition, social advancement of female induces weakened supporting function of family, and all these issues generate the problem of protection for the aged as significant social problems. Author conducted oral inspection and questionnaire for the aged in some welfare facilities in Gyeongnam location from December 2005 to February 2006 to improve quality of life and oral hygiene of the aged. Through gathered data, the actual condition of oral hygiene management on the aged person in welfare facility was evaluated as fundamental data for project development on oral hygiene of aged person. Through the analysis of inspected data, the following conclusions are derived. 1. Management status of oral hygiene is mostly not good, and toothbrushing per day is 'one time' for the most cases. 2. In free-of-charge facility, monthly allowance is 'under 50 thousand won' for the most cases. 3. Time for visiting oral treatment facility is on 'when toothache is occurred' for the most cases. For treatment content, 'prosthetic dentistry' takes 36.8% in charged facility, and 'tooth extraction' is 27.0% for free-of-charge facility. 4. Average DMFT index of the aged in charged facility is 16.81, and free-of-charge facility is 21.71. 5. Average number of functional teeth in charged facility is 15.22, and free-of-charge facility shows 7.29. 6. Average number of remained teeth in charged facility is 15.71, and the umbe in free-of-charge facility is 9.04. 7. Average number of extractable teeth in charged facility is 0.48, and for free-of-charge facility, the number goes up to 1.70.

The purpose of the study is to analyze the housing problems of single-person household in 20-35 age group. Using the survey of Household's Consumption in 2014, we estimated the housing demand function of young single-person household in Seoul. As a result, the coefficient of the permanent income for young single-person household housing was significantly lower than other groups and the housing demand was also lower than others. Since current income isn't come up to permanent income enough, the housing consumption of young single-person household shrinks. It implies the role of the housing financial market is less activated. That is, the difficulty of realization of permanent income and lack of housing finance are the main cause of the imbalance of housing demand of one young person. Therefore, it implies that in order to alleviate the housing problem of the young single-person household, a policy to balance the permanent income with the housing demand is needed.

Objective : To estimate the burden of diseases in Korea especially caused by major cancers using the YLL(years of life lost due to premature death) measurement. Methods : First, we determined the parameters: such as age-specific standard life expectancy, age on death, sex, cause of death by analyzing the national death certificate data and life table collected during 1996 provided by the National Statistical Office. Secondly, we estimated the age group-specific YLL by employing standard expected years of life lost(SEYLL). Thirdly, final burden of disease due to premature death was estimated by using YLLs measurement which developed by global burden of disease study group. Results : The burden of premature death by cancer for male was attributed mainly to liver cancer(514.5 person-year), stomach cancer(436.4 person-year), and lung cancer(367.7 person-year). Each of these cancers was responsible for the loss of over 100 person-year based on our YLL measurement. The burden of premature death by cancer for female was attributed mainly to liver cancer(135.1 person-year), stomach cancer(252.1 person-year), and lung cancer(121.8 person-year). Each of these cancers was responsible for the loss of over 100 person year based on our YLL measurement. Conclusion : We found the YLL method employed in this study was appropriate to quantify the burden of premature death. Thereby, it would provide a rational bases to plan a national health policy regarding premature death caused by cancer.

The purpose of this study is to investigate the limitations of virtual space game contents staying in the first-person viewpoint in the field of digital games with various genres through precedent researches and case studies, and to investigate the differences of immersion, presence, and fun based on the user interfaces, such as the viewpoints (first-person, third-person) and haptic feedback. The experimental results show that when the game is the first-person with the haptic feedback, the immersion, presence, and fun increase. However, the interaction effect between the virtual space environment and the game viewpoint was not found. As a result, it is appropriate to use the haptic feedback and the first-person viewpoint in the virtual reality games, but the fact that the game viewpoints and the virtual space environment are not huge relevant, and the third-person viewpoint is more popular than first-person viewpoint game, therefore the possibility of a third-person viewpoint game would be suggested.

This study examined the effects of eating alone, meal type, and dietary lifestyles on healthy eating capability of one-person households. We analyzed the mediation effects of weekly frequencies of each meal type taken by one-person households between eating habits such as eating alone and dietary lifestyles of one-person households and healthy eating capability. We also analyzed data from the 2019 Food Consumption Behavior Survey using a sample of 688 one-person households. Factor analysis, latent profile analysis, structural equation model analysis was conducted; direct and indirect effects of independent variables were tested using bootstrap method. The major results were as follows. Frequency of eating alone was about 10 times a week on average; one-person households had home-made meals about 12 times a week, for restaurant meals, 4 times, for delivered/take-out food, 0.39 times, and for other types, 0.44 times. Weekly frequencies of eating alone and meal types taken by one-person households were significantly different among the different socio-demographic groups. Dietary lifestyle was classified into four classes: traditional, health ignorant, food lifestyle ignorant, and balanced. Eating alone and dietary lifestyle had a significant effect on weekly frequency of each meal type. Frequencies of eating alone, balanced dietary lifestyle, and taking home-made meals had a positive direct effect on healthy eating capability, and frequency of taking delivered or take-out food and food consumption ignorant lifestyle had a negative direct effect. Eating alone, balanced and traditional dietary lifestyles had a positive indirect effect through the meal type; however, watching Mug-bang had a negative indirect effect.

Background: The purpose of this study is to provide the data for discussions related to oral health promotion policies for single-person households by analyzing the status of unmet dental needs and related factors in single-person households in Korea, based on the Anderson model. Methods: The data, obtained from 544 single-person households of those over 20 years old who were targeted for the 6th Korea National Health and Nutrition Examination Survey, were analyzed through a complex sample frequency analysis, complex sample cross analysis (Rao-Scott chi-square test), and complex sample binary logistic regression analysis on a complex sampling design. Results: The most frequently given reason for an unmet dental need among single-person households was economic (52.4%). Factors related to the unmet dental needs of single-person households are smoking, which is a predisposing factor; personal income levels, which are an enabling factor; chewing discomfort; and limited daily activities, which are need factors. Smokers, the high-income group, the chewing-discomfort group, and the limited activity group showed high unmet dental care experience. Smokers had a 2.75 times higher rate of unmet dental care than non-smokers, and the high-income group had a 5.29 times higher rate of unmet dental needs than the median group. The rate of unmet dental needs for the chewing discomfort group was 3.27 times higher than the non-chewing discomfort group, and the limited activity group had a 7.87 times higher rate of unmet dental needs than the non-limited activity group. Conclusion: It is necessary to map out policies designed to help maintain and promote met dental needs considered to be internally heterogeneous to single-person householders, based on the Anderson model.

Nowadays, gun crimes occur very frequently not only in public places but in alleyways around the world. In particular, it is essential to detect a person armed by a pistol to prevent those crimes since small guns, such as pistols, are often used for those crimes. Because conventional works for armed person detection have treated an armed person as a single object in an input image, their accuracy is very low. The reason for the low accuracy comes from the fact that the gunman is treated as a single object although the pistol is a relatively much smaller object than the person. To solve this problem, we propose a novel algorithm called APDA(Armed Person Detection Algorithm). APDA detects the armed person using in a post-processing the positions of both wrists and the pistol achieved by the CNN-based human body feature detection model and the pistol detection model, respectively. We show that APDA can provide both 46.3% better recall and 14.04% better precision than SSD-MobileNet.
