The single cell gel electrophoresis (comet) assay is one of the useful tools for the study of genetic damage in humans exposed to environmental mutagens and carcinogens. This study was undertaken to evaluate the status of DNA damage in peripheral lymphocytes depending on their sex, age, smoking habits, and other factors in normal healthy Korean population. The 99 volunteers included in the study and out of these, 36 volunteers were smoker and 63 volunteers were non-smoker aged between 20-59 years. All individual answered a questionnaire that assessed their general information including smoking habits and the extent of the environmental tobacco smoke (ETS) exposure, and blood samples were obtained. There was a statistically significant difference in the extent of DNA damage between smoker and non-smoker (p<0.001). A significant difference was also observed between male and female (p<0.001) and amongst the different group of age (p<0.005), however, correlation analysis showed that only smoking habit was a significant factor for DNA damage. No significant effect of smoking duration, number of cigarettes smoking a day, SPY (smoke pack years) in smokers and environmental tobacco smoke exposure in non-smokers on the status of DNA damage was observed.

The aim of this study was to investigate the interrelationship among urinary excretion dietary habit of Na, Ca intake and hormonal factors in 22 hypertensive and 30 normotensive hospitalized patients. The results were summarized as follows : 1. Urinary excretion of Na in normotensive patients was not significantly different from that of hypertensive patients, while Ca excretion(as expressed on the basis of mg of creatinine) was significantly higher in hypertensive patients. 2. Habitual dietary intake of Na, Ca in hypertensive patients were not significantly different from those of normotensive patients. 3. There were no significant differences in mean plasma renin activity, aldosterone and parathyroid hormone(PTH) level between two groups. However, systolic pressure significantly correlated with PTH(r=0.2597) and aldosterone level(r=0.24648)(P<0.05). In this study blood pressure did not show any significant relationship between urinary Na excretion and habitual dietary Na intake of Na. It is speculated that individual difference of Na sensitivity might result in heterogenous blood pressure response to dietary Na intake. Higher Ca excretion in hypertensive subjects suggested a future study on the interrelationship between Ca metabolism and aldosterone system in hypertension.

This study reports the relationship between life-style and physical, mental health status in college students. The questionnaire survey was carried out from September to October, 1991. The questionnaire included life-style, physical health condition centered on unhealthy habits and complaints about physical symptoms, and mental condition which was assessed by Zung's self-rating depression scale(SDS). Days absent from school during the last year in males(3.6) were significantly more than those in females (1.0). Days catching the common cold were more in females than in males. The amount of complaints and the SDS score were significantly higher in females than in males. In the relationship between physical and mental health status and individual health habits, abscence-days from school significantly correlated with regular life, snacking, physical exercise, smoking, drinking. The amount of complaints and the SDS score were significantly associated with regular life, regular meal-time, eating breakfast, nutritional balance and physical exercise. In the relationship between health practice index to health status, the group having good habits showed significantly less days catching the common cold, less complaints, less SDS score and less amount of stress. It was also shown that life-style correlated with physical and mental health status.

The Korean version of the morningness-eveningness questionnaire (MEQ) and sleep habits inventory were administered to 1,038 Korean male daytime workers and were analyzed according to age and chronotype to determine what these factors reveal about sleep habits in view of phase difference of circadian rhythm. The mean and distribution of scores on the MEQ moved significantly toward the morning type with aging. Bedtimes and waking times were progressively later from the morning, intermediate, to evening types, and were also earlier with aging. Preferred bedtimes and waking times showed more distinct differences than did the habitual times in each chronotype. The percentage of subjects who answered that sleep length was 'short', mood upon waking was 'bad', and variabilities of bedtime and sleep length were 'large' were greater in the young and evening types than in the elder and morning types, respectively. These findings suggested that subjects were shifted toward the morning type and the phase of circadian rhythm had moved forward with aging. Preferred bedtime and waking time were a better reflection of individual circadian rhythms than habitual bedtime and waking time.

A tendency of active exchanges of newly-generated culture and mind following with the world globalization has been leading totally new concept of social level, its life style and spending habit. According to these social movements, people's way of thinking has been shifted from we-centered to I-centered, which generate (cause) individualism. The tendency of putting much weight on individuality prevailed in the society grows the social awareness on individual's needs and tastes and ultimately lead overall movement of longing for single life style. The rate for singles also has been dramatically increased these days, and expects reach 30 percents of overall popularity in 2010. Therefore, various new concepts of residences for singles have been introduced recently, such as an office apartment, condominium and serviced residents, which combines concepts of both a hotel and an apartment. In this thesis, six examples of newly-styled residence for singles would be researched in every aspect, such as its service, facilities and so on. Although the fact of that overall service quality of new type residence now is well constructed and performed is derived from this research, I expect to contribute more various and advanced service quality into new social movement and new type of residences for single life, and finally provide satisfactory life style for singles.

Objectives: Eight Constitution Medicine (ECM) categorizes individuals into eight constitutions based on physiological differences in organ relations and recommends different diets for different constitutions. This study presents a preliminary analysis of the effect of following constitutional food regimens on quality of life and health outcomes for different constitutions. Methods: This cross-sectional, comparative study used subjects recruited from Essen University Hospital Traditional Chinese Medicine Center in Germany. From a convenience sample of 243 Germans, those in the groups Hepatonia/Cholecystonia (n = 95) and Pulmotonia/Colonotonia (n = 26) were analyzed for health outcomes in relation to their dietary habits of either including or avoiding meat. Health outcomes were measured with SF-36, self-reported survey. Results: The two groups had no significant differences in the health outcomes of SF-36. However, subjects in Hepatonia/Cholecystonia who had followed their dietary habit for more than 20 years had significantly better scores on general health, social functioning, mental health, emotional role functioning, and mental component scores than those in Pulmotonia/Colonotonia, regardless of their meat intake. Conclusions: This study established initial groundwork for considering patients' constitutions when evaluating health outcomes and their relation to diet. Further studies are warranted on the effects of regulating food intake according to individual constitution.

Providing services using kiosks is actively carried out between suppliers and consumers. These service processes have recently begun to play a dominant role in transactions. However, previous self-service technology (SST) studies or kiosks have not fully reflected the changing environment surrounding these different technologies. To cover the updated business environments, we combined qualitative and quantitative research methods. Through qualitative research and a review of previous studies, the variables emphasized as motivations and constraints for kiosks use and those that can be newly illuminated were selected for this study. We then applied the variables to the research model to assess their influence. In terms of the motivations for using kiosks, the results suggest that perceived usefulness and compatibility as service quality, forced use, and perceived service providers' efficiency as provider polices, absorptive capacity, and habit as an individual characteristic and social influence as a subjective norm have a significant effect on the attitude toward kiosks. In terms of constraints, difficult to use and need for interaction predicts the attitude toward kiosks. Attitude toward kiosks, perceived behavioral control, and social influence are directly related to the intention to use kiosks. Lastly, intention to use kiosks plays a significant role as an antecedent of revisit intention. Using these empirical results, we propose both academic and practical implications for future kiosks use.

Researchers have been continuously interested in the adoption of information technology (IT) since it is of great importance to the information systems success and it is also an important stage to the success. Adoption alone, however, does not ensure information systems success because it does not necessarily lead to achieving organizational or individual objectives. When an organization or an individual decide to adopt certain information technologies, they have objectives to accomplish by using those technologies. Adoption itself is not the ultimate goal. The period after adoption is when users continue to use IT and intended objectives can be accomplished. Therefore, continued IT use in the post-adoption period accounts more for the accomplishment of the objectives and thus information systems success. Previous studies also suggest that continued IT use in the post-adoption period is one of the important factors to improve long-term productivity. Despite the importance there are few empirical studies focusing on the user behavior of continued IT use in the post-adoption period. User behavior in the post-adoption period is different from that in the pre-adoption period. According to the technology acceptance model, which explains well about the IT adoption, users decide to adopt IT assessing the usefulness and the ease of use. After adoption, users are exposed to new experiences and they shape new beliefs different from the thoughts they had before. Users come to make decisions based on their experiences of IT use whether they will continue to use it or not. Most theories about the user behaviors in the pre-adoption period are limited in describing them after adoption since they do not consider user's experiences of using the adopted IT and the beliefs formed by those experiences. Therefore, in this study, we explore user's experiences and beliefs in the post-adoption period and examine how they affect user's intention to continue to use IT. Through deep literature reviews on the construction of subjective beliefs by experiences, we draw three meaningful constructs which theoretically have great impacts on the continued use of IT: perceived habit, confirmation, and computer self-efficacy. Then, we examine the role of the subjective beliefs on the cognitive/affective attitudes and intention to continue to use that IT. We set up a research model and conducted survey research. Since IT use implies interactions among a user, IT, and a task, we carefully selected the sample of users using same/similar IT to perform same/similar tasks, to exclude unwanted influences of other factors than subjective beliefs on the IT use. We also considered that the sample of users were able to make decisions to continue to use IT volitionally or at least quasi-volitionally. For each construct, we used measurement items recognized for reliability and widely used in the previous research. We slightly modified some items proper to the research context and a pilot test was carried out for forty users of a portal service in a university. We performed a full-scale survey after verifying the reliability of the measurement. The results show that the intention to continue to use IT is strongly influenced by cognitive/affective attitudes, perceived habits, and computer self-efficacy. Confirmation affects the intention to continue indirectly through cognitive/affective attitudes. All the constructs representing the subjective beliefs built by the experiences of IT use have direct and/or indirect impacts on the intention of users. The results also show that the attitudes in the post-adoption period are formed, at least partly, by the experiences of IT use and newly shaped beliefs after adoption. The findings suggest that subjective beliefs built by the experiences have deep impacts on the continued use. The results of the study signify that while experiencing IT in the post-adoption period users form new beliefs, attitudes, and intentions which may be different from those of the pre-adoption period. The results of this study partly demonstrate that the beliefs shaped by the behaviors, those are the experiences of IT use, influence users' attitudes and intention. The results also suggest that behaviors (experiences) also change attitudes while attitudes shape behaviors. If we combine the findings of this study with the results of the previous research on IT adoption, we can propose a cycle of IT adoption and use where behavior shapes attitude, the attitude forms new behavior, and that behavior shapes new attitude. Different from the previous research, the study focused on the user experience after IT adoption and empirically demonstrated the strong influence of the subjective beliefs formed in the post-adoption period on the continued use. This partly confirms the differences between attitudes in the pre-adoption and in the post-adoption period. Users continuously change their attitudes and intentions while experiencing (using) IT. Therefore, to make users adopt IT and to make them use IT after adoption is a different problem. To encourage users to use IT after adoption, experiential variables such as perceived habit, confirmation, and computer self-efficacy should be managed properly.

The chances of disease pattern increased the importance of Health-promoting Lifestyle and a large part of the Health-promoting Lifestyle is associated with individual's habit. Health-promoting Lifestyle among nurses is very important because nurses could be a role model of patients and possibly influence many patients. The purpose of this study was oat on1y to assess how hospital nurses practice their Health-promoting Lifestyle but also to identify those affecting determinants. The subjects were 392 nurses working at 3 different hospital in Seoul. These data were collected by self administered questionnaire from April 27 to May 20, 2000. This study examined Health-promoting Lifestyle using In Sook Park's model, individual characteristics. Behavior-specific Cognitions and Affect factors using Pender's model and tried to fine out their relationships. The instruments used in this study were Health-promoting Lifestyle Profile developed by In Sock Park(1995). Likert's four-point scale was used also in this research. The percentage, mean standard deviation, AVNOVA, Pearson's correlation coefficient and multiple regression in the SAS package were used to analyze the data. The results of this study were as follows; 1. 52.3% of sample were aged between 25 and 29, 67.1% were single, 55.6% were university graduates, 51.8% earned 1.5 to 2.0 million won, 57.9% slept for d to 8 hours, 74.5% stated they were healthy. 2. 32.7% of sample worked in surgical gird department, 82.4% worked in 3 shift, 26.3% have been working as nurses for 5 to 7 years. Average score of Perceived self-efficacy was 3.63, Perceived benefits of action was 3.25, Social support was 2.75, and Perceived barriers to action was 1.87 which was the lowest score. 3. The average score if the performance in Health-promoting Lifestyle variable was 2.45 which was lower than previous study. The sanitary life Was 3.18 which was the highest score, harmonious relationship 3.13, emotional support 2.90. The variable with the highest degree of performance was the sanitary life, whereas the one with the west degree was the health diet. 4. There were no significant difference in perceived benefits of action with individual's a character, but in Perceived bait his of action there were significant differences with age(p<.01), marital status(p<.05), housing(p<.05), and Perceived health status(p<.05). In Perceived self-efficacy, there were significant differences with educational level(p<05), sleeping hours(p<.05), and BMI(p<.05). In Social support here were significant difference with housing and sleeping hours.
