This study set out to analyze the relationships between the senior citizens' dental health activities and dental health conditions, to provide basic data to develop a program for their better dental health, and finally to search for the ways to improve their life quality through dental health care. The subjects were 142 senior citizens(58 were male and 84 were female) who were 65 years old or older and visited a dental hospital or clinic in the Seoul metropolitan area from April 17 to April 28, 2006. With the cooperation from the dentists, the investigators examined their dental conditions and conducted one-on-one interviews to collect the information about their demographic characteristics, dental health activities, and subjective dental health conditions. The collected data were analyzed with T-test, ANOVA and Pearson's correlation coefficient using the SPSS WIN 11.5 program. The analysis results were summarized as follows: First, 58 men(40.8%) and 84 women(59.2%) consisted of the subject group, where percentage of the female participants was bigger Those who were aged from 65 to 69 made the biggest age group in the subjects, accounting for 58.5% with 83. Second, those who had three dental caries or less and then didn't treat them or treated them(F) accounted for the biggest percentage with 117(82.4%) and 72(50.7%) respectively. As for the remaining teeth, the biggest number of them(40 subjects, 28.2%) had three or less remaining. Third, it turned out the female subjects had a higher level of dental health activities than their male counterparts(P = 0.00). As for living expenses, those who were paid salary or earned income themselves carried out their dental health activities in a higher level than those who lived on the benefit from the government(p = 0.02). Fourth, the subjects' subjective dental health conditions had negative correlations with their dental caries not treated. And there were positive correlations between their dental caries not treated and dental caries lost and between their dental caries treated and remaining teeth. Fifth, those subjects who earned their living expenses themselves had the most dental caries treated at 5.4(p = 0.02), and there was statistically significant difference with the numbers. Sixth, those subjects who brushed their teeth in their own manner had 11.8 teeth lost(p = 0.05), which was more than the number of those who brushed their teeth in other methods. And there was statistically significant difference among them. The remaining teeth were found most at 17.3(p = 0.00) among those who brushed their upper and lower teeth separately. In addition, those who visited the public health center often had significantly more teeth treated(4.3) than others(p = 0.00).

Rheumatoid arthritis is a chronic systematic disease with unpredictable course of exacerbation and remission, characterized by pain, joint deformity and reduced activity by joint limitation. The growing public awareness of the need for health management of chronic illnesses, provides impetus for nursing to demonstrate social effectiveness by active nursing intervention in this vast area in general, and with rheumatoid condition in particular. However, nursing interventions to date have not demonstrated its active participation in the management of chronic conditions. Nursing intervention for the patients having rheumatoid arthritis is one such area that needs to be studied intensively and to demonstrate their effectiveness empirically. The purposes of this study were two fold : first, to develop a comprehensive program that was intensified with therapeutic joint exercises in water, self-help group activities and utilization of self-efficacy promoting strategies : and secondly, to determine the effect of aquatic exercise program on pain, physiological changes and quality of life in the rheumatoid arthritis patients. Thirty five female subjects participating in this study were selected from outpatients in the Rheumatism Center, Hanyang University hospital. The period of data collection was from December, 1992 to March, 1993 in seoul and Taejeon. Subjects in Taejeon were assigned to the experimental group. The comprehensive aquatic exercise program for the experimental group was carried out three times a week for 6 weeks in regular swimming pool. Subjects in Seoul did not participated in the program, and treated as the control group. Data were analyzed with repeated measure MANCOVA, t-test, ANCOVA, percentage of change, Kruskal-Wallis 1-Way ANOVA using SPSS $PC^+$ program. Results were obtained as follows : 1) Scores on Korean pain scale, Numeric pain score, and RAI score of the experimental group were significantly lower than those of the control group (t=2.11, p=0.022 ; F=4.40, p=0.044 : t=3.10, p=0.002). 2) There was significant improvement in the physiological parameters (higher joint movement parameters, F=15.64, p=0.024 ; higher lean body mass, percentage of change=+12.2, lower body weight, t=1.01, p=0.026 : lower ESR, t=1.69, p=0.001) in the experimental group compaired with subjects In the control group. 3) There was significant improvement in the specific self-efficacy score through the comprehensive aquatic exercise program(t=2.73, p=0.011), but not in the general self- efficacy score(t=0.62, p=0.113). 4) The quality of life failed to show significant improvement in the experimental group as compaired with the control group (F=3.69, p=0.064). 5) In the experimental group, findings from additional analysis showed no significant difference in the specific self-efficacy between those who continued to aquatic exercise after completing 6 week program and those who stopped (X2=0.086, p=0.690). Therefore, adherence to aquatic exercise program for 6 weeks seem to be affected mainly by self-help group activities. An indepth study to delve into articulation of mechanisms affecting the effect of aquatic exercise program be recommended. A further study is necessary to determine the difference in the effect of group and individual aquatic exercise program, to assess factors affecting adherence to exercise for an extended length of time.

The purpose of this study is the investigation of the effects of user participation, network effect, social influence, and usefulness on stickiness and continued use on Internet communities. In this research, stickiness refers to repeat visit and visit duration to an Internet community. Continued use means the willingness to continue to use an Internet community in the future. Internet community-based companies can earn money through selling the digital contents such as game, music, and avatar, advertizing on internet site, or offering an affiliate marketing. For such money making, stickiness and continued use of Internet users is much more important than the number of Internet users. We tried to answer following three questions. Fist, what is the effects of user participation on stickiness and continued use on Internet communities? Second, by what is user participation formed? Third, are network effect, social influence, and usefulness that was significant at prior research about technology acceptance model(TAM) still significant on internet communities? In this study, user participation, network effect, social influence, and usefulness are independent variables, stickiness is mediating variable, and continued use is dependent variable. Among independent variables, we are focused on user participation. User participation means that Internet user participates in the development of Internet community site (called mini-hompy or blog in Korea). User participation was studied from 1970 to 1997 at the research area of information system. But since 1997 when Internet started to spread to the public, user participation has hardly been studied. Given the importance of user participation at the success of Internet-based companies, it is very meaningful to study the research topic of user participation. To test the proposed model, we used a data set generated from the survey. The survey instrument was designed on the basis of a comprehensive literature review and interviews of experts, and was refined through several rounds of pretests, revisions, and pilot tests. The respondents of survey were the undergraduates and the graduate students who mainly used Internet communities. Data analysis was conducted using 217 respondents(response rate, 97.7 percent). We used structural equation modeling(SEM) implemented in partial least square(PLS). We chose PLS for two reason. First, our model has formative constructs. PLS uses components-based algorithm and can estimated formative constructs. Second, PLS is more appropriate when the research model is in an early stage of development. A review of the literature suggests that empirical tests of user participation is still sparse. The test of model was executed in the order of three research questions. First user participation had the direct effects on stickiness(${\beta}$=0.150, p<0.01) and continued use (${\beta}$=0.119, p<0.05). And user participation, as a partial mediation model, had a indirect effect on continued use mediated through stickiness (${\beta}$=0.007, p<0.05). Second, optional participation and prosuming participation significantly formed user participation. Optional participation, with a path magnitude as high as 0.986 (p<0.001), is a key determinant for the strength of user participation. Third, Network effect (${\beta}$=0.236, p<0.001). social influence (${\beta}$=0.135, p<0.05), and usefulness (${\beta}$=0.343, p<0.001) had directly significant impacts on stickiness. But network effect and social influence, as a full mediation model, had both indirectly significant impacts on continued use mediated through stickiness (${\beta}$=0.11, p<0.001, and ${\beta}$=0.063, p<0.05, respectively). Compared with this result, usefulness, as a partial mediation model, had a direct impact on continued use and a indirect impact on continued use mediated through stickiness. This study has three contributions. First this is the first empirical study showing that user participation is the significant driver of continued use. The researchers of information system have hardly studies user participation since late 1990s. And the researchers of marketing have studied a few lately. Second, this study enhanced the understanding of user participation. Up to recently, user participation has been studied from the bipolar viewpoint of participation v.s non-participation. Also, even the study on participation has been studied from the point of limited optional participation. But, this study proved the existence of prosuming participation to design and produce products or services, besides optional participation. And this study empirically proved that optional participation and prosuming participation were the key determinant for user participation. Third, our study compliments traditional studies of TAM. According prior literature about of TAM, the constructs of network effect, social influence, and usefulness had effects on the technology adoption. This study proved that these constructs still are significant on Internet communities.

Osteoporosis is the disease that is the most controversial issue with the aging tendency in 1990. It is an important issue in dealing with the health management for women in middle life. This study is designed to determine the relationships among the level of the knowledge of osteoporosis, the health promoting behaviors and the quality of life. The test has conducted a questionnaire survey of women with osteoporosis. This is a study that focused an interrelation of above issues and its purpose is to gain a foundation of a nursing intervention that can help to improve the qualify of life of an osteoporosis patients. The method of collecting data is collecting a questionnaire survey, individual interviews and records and the collected 123 questionnaire surveys are utilized for an data analysis. Questionnaire surveys are conducted in K and S Universities infirmaries and K general hospital in Seoul and C and J general hospital in near Seoul area from Sep. 27th to Nov. 4th, 2000. The instruments of this study were as follows: Yoon's used the revised and supplemented instrument to test the level of the knowledge of osteoporosis and she referred to the substance of Cassells & Knotz. Lee's revised and supplemented the instrument called Health Promoting Life style Profile that were invented by Walker, Sechrist & Pender and she used it to test the health promoting behaviors with the questionnaires added by this researcher. They are not related to the quality of life but relevant to the patients. Ro's tested the quality of life with the instrument that was invented by herself. The results of this study were as follows. 1. The general characteristics of this study subjects showed that the age of the patients was concentrated from 50 to 59. The periods after menopause was mainly from 6 to 10 years. Subjective symptoms that patients usually complain were musculoskelectal symptoms. 2. The results of measuring the level of the knowledge of osteoporosis, the health promoting behaviors and the quality of life were following. The level of the knowledge was the score 19.83 and it was above middle score out of the score 27 as full marks. In the result of the health promoting behaviors test, the score average was 2.58 with 4 point rating scale and it was about middle score. The quality of life test showed that average score was 2.92 with 5 point rating scale and it indicated that the quality was also around middle score. 3. The statistical test in the activities for promoting health according to the general characteristics of the patients showed that only monthly income has statistically significant difference(F-4.761, p=.004). The same test for the qualify of life indicated that the quality of life was higher from 1 to 5 years after menopause but it was not meaningful statistically. 4. In the correlation among the level of knowledge of osteoporosis, the health promoting behaviors and the qualify of life of the patients, showed a relationship between the health promoting behaviors and the qualify of life. The higher the health promoting behaviors, it was also higher the quality of life. But it was statistically significant with significant positive correlation.

The liquefaction phenomenon that occurred during the Pohang earthquake (M_L=5.4) brought new awareness to the people about the risk of liquefaction caused by the earthquake. Liquefaction hazard maps with 2 km grid made in 2014 used more than 100,000 borehole data for the whole country, and regions without soil investigation data were produced using interpolation. In the mapping of macro liquefaction hazard for the whole country, the site amplification effect and the ground water level 0 m were considered. Recently, the Ministry of Public Administration and Security (2018) published a new site classification method and amplification coefficient of the common standard for seismic design. Therefore, it is necessary to rewrite the liquefaction hazard map reflecting the revised amplification coefficient. In this study, the results of site classification according to the average shear wave velocity in soils before and after revision were compared in the whole country. Also, liquefaction assessment results were compared in Gangseo-gu, Busan. At this time, two ground accelerations corresponding to the 500 and 1,000 years of return period and two ground water table, 5 m for the average condition and 0 m the extreme condition were applied. In the drawing of liquefaction hazard map, a 500 m grid was applied to secure a resolution higher than the previous 2 km grid. As a result, the ground conditions that were classified as S_C and S_D grounds based on the existing site classification standard were reclassified as S₂, S₃, and S₄ through the revised site classification standard. Also, the result of the Liquefaction assessments with a return period of 500 years and 1,000 years resulted in a relatively overestimation of the LPI applied with the ground amplification factor before revision. And the results of this study have a great influence on the liquefaction assessment, which is the basis of the creation of the regional liquefaction hazard map using the amplification factor.

This study was conducted to examine obese children's self-efficiency feeling and health promotion behavior in order to provide basic information on prevention of children obesity. Data were collected in June, 2001 from 349 normal weight children and 351 obese children, who were fifth or sixth graders at 14 primary schools located in Seoul, Busan, Daegu, Gwangju, Ansan, chungju, and Gumi. The data were analyzed through using Chronbach's $\alpha$, frequency analysis, $X^2-test$, ANOVA, and Pearson correlation. The results of this study can be summarized as follow. 1. The factor of children obesity was significantly different in the variables of sex, parents obesity, brother or sister obesity, father's occupation, level of living, health condition, and satisfaction level with their bodies. On the other hand, it was not significantly different in the variables of father's education level, mother's education level, mother's occupation, level of father's concern about health, and level of the children's concern about health. 2. In the case of normal weight children, dietary efficiency feeling was significantly different in the variables of level of father's concern about health and level of children's concern about health. In th case of obese children, the dietary efficiency feeling was significantly different in the variables of mother obesity, parents' education level, father's occupation, and the children's satisfaction level with their bodies. In the case of normal weight children, exercise efficiency feeling was significantly different in the variables of sex, level of parents's concern about health, and level of the children's concern about health. In the case of obese children, the exercise efficiency feeling was significantly different in the variables of grade, brother and sister obesity, parents' education level, father's occupation, and the children's satisfaction level with their bodies. In the case of normal weight children, social efficiency feeling was significantly different in the variables of brother and sister obesity, parents' education level, level of parents' concern about health, and level of the children's concern about health. In the case of obese children, the social efficiency feeling was significantly different in the variables of parents' education level, father's occupation, level of living, the children's health condition, and the children's satisfaction level with their bodies. 3. In the case of normal weight children, personal hygiene was significantly different in the variables of sex, level of parents's concern about health, and level of the children's concern about health. In the case of obese children, the personal hygiene was significantly different in the variables of parents' education level, father's occupation, mother's occupation, level of living, and level of parents' concern about health. In the case of normal weight children, dietary habit was significantly different in the variables of sex, level of parents's concern about health, and level of the children's concern about health. In the case of obese children, the dietary habit was significantly different in the variables of father's education level, mother's education level, level of living, and the children's satisfaction level with their bodies. In the case of normal weight children, exercise habit was significantly different in the variables of grade, sex, father's education level, mother's education level, and level of children's concern about health. In the case of obese children, the exercise habit was significantly different in the variables of grade, mother obesity, parents' education level, father's occupation, level of parent' concern about health, the children's health condition, and the children's satisfaction level with their bodies. In the case of normal weight children, prevention of infectious diseases was significantly different in the variables of sex, father's occupation, level of parents' concern about health, and level of the children's concern about health. In the case of obese children, the prevention of infectious diseases was significantly different in the variables of mother's education level and father's occupation. In the case of normal weight children, prevention of accident was significantly different in the variables of mother's education level, level of parents' concern about health, and level of the children's concern about health. In the case of obese children, the prevention of accident was significantly different in the variables of brother and sister obesity and mother's occupation. In the case of normal weight children, mental health was significantly different in the variables of father obesity, brother and sister obesity, parents' education level, and level of the children's concern about health. In the case of obese children, the mental health was significantly different in the variables of parents' educational level, father's occupation, mother's occupation, level of living, and the children's health condition. 4. According to the correlation between self-efficiency feeling and health promotion behavior, the higher the self-efficiency feeling was, the higher the level of health promotion behavior was. 5. The children obesity was influenced by the factors of level of living, level of parents' concern about health, the children's health condition, level of the children's concern about health, the children's satisfaction level with their bodies, dietary efficiency feeling, exercise efficiency feeling, social efficiency feeling, personal hygiene, dietary habit, exercise habit, prevention of infectious diseases, prevention of accident, and mental health. From the results of this study, it is clear that obese children's self-efficiency feeling is closely related with health promotion behavior. Therefore, it is necessary to strengthen children's self-efficiency feeling in order to make children control efficiently obesity for themselves.

This study analyzes the process of overcoming prejudice and discrimination experiences of mothers with disabilities and looks for improvement points. It is interviewed 9 mothers of children with disabilities who were experiencing prejudice and discrimination while raising children with disabilities. The data collection was conducted from October to November, 2018 and one by on one in depth interview by using semi - structured questionnaires. Data analysis was done through consensual qualitative research (CQR). The result of CQR while it is a experiencing the process of prejudice and discrimination as well as coping the raising disabled children. 'Prejudice and discrimination experience of mothers with disabilities' and 'overcoming of discrimination experiences of mothers with disabilities' were derived. And the seven sub-regions, 28 categories, were finally constructed. The results of the study are as follows. Firstly, Prejudice and discrimination experiences of mothers with disabilities in raising children with disabilities are view of looking at children with disabilities comparing to those of normal children and children with disabilities. It seems that they want to treat the disabled child as the general child with an attitude of understanding and accepting the disabled child rather than looking at the disabled child with wrong perception, prejudice, stereotypes and rejection. Secondly, The process of overcoming the discrimination experiences of the mother of the disabled child is strengthening the cohesion and cohesion within the family in the process of accepting and coping with the disability family of the child with disabilities even if they raise the child with disability and have difficulties such as recognition bias and discrimination of the general public. Based on the results of this study, we suggested practical and policy implications for the mother's psychological stability of the child with disability and the disabled child's healthy life.

In order to improve the quality of consumption in senior generation, it is necessary to build trust in the digital consumption environment. However, there are limitations from previous researches on consumption in the digital environment that has mainly focused on Millennial and Z generations. Therefore, this study aims to examine the antecedents of digital consumption trust and to explore the market segments of senior generation created by the dynamics of these antecedents. In addition, in order to provide practical implications, we investigate the difference in the level of perceived digital consumption trust using segmentation. This study, therefore, used 2021 Korea's consumer life index data conducted by the Korea Consumer Agency for general consumers, and only consumer data of 60s and older are extracted for the analysis. As a result, we confirm from the main results that the three antecedents, consumer competency, perceived corporate responsibility, and local community's problem-solving environment, are significant in building the digital consumption trust in the senior generation. It is academically significant in this aspect to look at approaches to improve senior customers' trust in digital consumption circumstances by dividing generations because generations exhibit varying levels of understanding of online consumption or digital consumption conditions. It is academically significant in this aspect to look at approaches to improve senior customers' trust in digital consumption circumstances by dividing generations because generations exhibit varying levels of understanding of online consumption or digital consumption conditions. Additionally, it is proposed as a practical implication that it should be managed so that significant improvements of customers, businesses, and regional public institutions are developed in order to allow the senior consumers to prepare trusted digital consumption circumstances.

Objectives: This study was carried out to evaluate the socio-demographic, style of living, and health related behaviors of community residents between urban and rural areas in Jeonbuk province. Methods: The data was obtained from 2,086 residents who lived in Jeonbuk province from July to September 2001 which included 1,238 residents in urban area and 848 residents in rural area. Results: The results were as follows; There were significant differences socio-demographic characteristics including occupation and educational level of the populations between urban and rural areas. In the urban populations, housewives, professional classes, and people who received collage graduate education were significantly higher, people who were engaged in the primary industries and lower educational classes(below middle school), in contrast, were significantly lower than in the rural populations. In the practice of health behavior, consumption of health foods and amount of exercise in urban populations were significantly higher than in the rural, whereas the state of health, prevalence of chronic disease, Body Mass Index(BMI), consumption of ethanol and cigarette, and hours of sleep were not significantly different between the urban and rural populations. In the eating habits, rate of surfeit, vaccination of hepatitis B, and screening of cancer in the urban populations were significantly higher than in the rural, rate of regular meal, taste of salted food, consumption of vegetables, in contrast. were significantly lower than in the rural. But, consumption of coffee, intake of meat, and periodic medical checkup were not significantly different between urban and rural communities. Logistic regression analysis revealed that the factors associated with subjective thought on health state were sex, age, occupation, educational level, exercise, and consumption of coffee. Logistic regression analysis to find related factor with prevalence of chronic disease was conducted. As a results, age, educational level, BMI, intake of meat, screening of cancer, and consumption of health foods were related to prevalence of chronic disease. Conclusions: The study showed that special attention to device the health plan are necessary and it suggested that consideration of regional differences are required to provide the community health projects.

This study is a fundamental research in the field of home economics education to enforce vocational competencies. It was carried out in the purpose of examining the recent economical and social environmental changes and its management system related to the vocational training in the field of home economics education. It seeks change in direction in relation to the National Competency Standard(NCS) based on revisions in the educational system. The method of study was mostly through reference and data analysis, professional advisory and public hearing. The main research results are as follows. First, the main environmental change factors in relation to vocational training have been integrated to the changes in; population structure, gender related economic activities, generation composition, communications technology, and innovation of living technique. These change factors are forecasting innovations in related industries, lifestyle changes, demand for manpower and changes in capabilities required for each specific profession. Second, according to the analysis of current home economics education training, vocational home educations high school accounts for 9.4% of the total number of specialized high schools, where 8 standard departments are specialized in and characterized into 137 different department names. Despite differences among departments, overall employment rate of graduates were measured 44.7%, which rates above the entrance rate of 41.9%. These numbers show great change since 2010(overall employment rate 16.9%, entrance rate 75.2%), a meaningful outcome resulting from changes in policy from the previous employment-centered education system. Third, NCS based on high school vocational home economics education system revision and investigations in change of direction in vocational home economics, this study attempts to provide background for revision from the development of NCS. It also provides proposals for restructuring division of current classification and departments of home economics education, and propositions for further future research.
