Cardio-cerebrovascular disease is one of the chronic diseases that often attack people in Korea, and in fact, it ranks second in terms of death rate. This disease can be prevented by improving lifestyle, usual health care is important. But, in Korea most of the prevention or management programs adopt passive methods like using guide books or giving lectures, so it is not very effective in preventing the disease. Presently, the smart health care market is being developed in Korea and overseas. As an example, quantified self is being spread through wearable devices which are intended to measure each individual's health conditions and quantify body data into numbers for bettering habits. Accordingly, this author will explore and discuss wearable health care devices so as to prevent and manage cardio-cerebrovascular disease in a more active way. First, this study has classified wearable health care devices presently commercialized or related with cardio-cerebrovascular disease into wrist, clothes, or attaching types by the way of their attachment and analyzed them. After that, summing that up, this author performed cross-tabulations with other ways of preventing cardio-cerebrovascular disease. This will contribute to improving one's health care behavior about disease more actively and also work as an active interdisciplinary mechanism in research dealing with how to prevent disease afterwards.

Purpose: This study was conducted to better understand the illness experiences and palliative care needs in community-dwelling persons with cardiometabolic diseases. Methods: This qualitative descriptive study was conducted with 11 patients (and three family members) among 28 patients contacted. Interviews were led by the principal investigator in her office or at participants' home depending on their preference. All interviews were digitally recorded and transcribed by a research assistant. The interviews were analyzed by two independent researchers using a conventional method. Results: Participants' ages ranged from 42 to 82 years (nine men and two women). Three themes were identified: (1) same disease, but different illness experiences; (2) I am in charge of my disease(s); (3) preparation for disease progression. Participants were informed of the name of their disease when they were diagnosed, but not provided with explanation of the diagnosis or meant or how to do self-care to delay the disease progression, which increased the feelings of uncertainty, hopelessness and anxiety. Taking medication was considered to be the primary treatment option and self-care a supplemental one. Advanced care plans were considered when they felt the progression of their disease(s) while refraining from sharing it with their family or health care professionals to save their concerns. All participants were willing to withhold life-sustaining treatment without making any preparation in writing. Conclusion: Education on self-care and advanced care planning should be provided to community-dwelling persons with cardiometabolic diseases. A patient-centered education program needs to be developed for this population.

Periodontal diseases occur from the interplay between increased bacterial response and the response of the host immune system over time. Anxiety and depression can impair immunological defense mechanisms, causing accumulation of periodontopathogens and thus exacerbating periodontal disease. We investigated the relationship of anxiety and depression to periodontal diseases in Korean women. In this study, 3,551 women aged ${\geq}19$ years were evaluated based on data from the first year (2010) of the Fifth Korea National Health and Nutrition Examination Survey. The analysis of the factors that caused periodontal diseases revealed that dental floss or interdental toothbrush nonuse behaviors have been shown to increase the risk of periodontal disease (odds ratio [OR], 1.49; 95% confidence interval [CI], 1.14~1.95). After adjusting for conditions such as age, marital status, income, educational level, economic activity, diabetes mellitus, smoking, drinking, and frequencies of toothbrushing and interdental cleaning, we found that anxiety and depression increased the risk of developing periodontal diseases (OR, 1.47; 95% CI, 1.04~2.09). People with anxiety and depression have a higher prevalence of periodontal diseases than people without anxiety and depression. Thus, periodic periodontal care and effective self-care education are needed to manage periodontal diseases.

This paper studies the stock market in which there are two types of investor, institutional and individual, whose information gathering and processing abilities are different. The institutional investor manages large funds and has powerful information sources. Whereas, the individual investor trades with a small amount of money and an information disadvantage. The model assumes that the institutional investor is more experienced and able to acquire relevant information earlier than the individual investor. On these assumptions, this paper shows a price continuation in the short run and a price reversal in the long run. The price continuation, or momentum, in the short run can be explained as follows. The early-informed institutional investor trades a stock, and as a result the stock price changes. Then the late-informed individual investor trades the same stock, and the stock price continues to move in the same direction in the short run. The reason for the price reversal in the long run is that since the individual investor has inferior information on the fundamental value of the stock, he tends to overreact to new information. So the stock price changes over its fundamental value initially and then regresses toward its fundamental value. In sum, both the price continuation and the price reversal are caused by the overreaction of the individual investor. The essay illustrates how these phenomena are stronger in the case where the proportion of the individual investor is higher. It also shows how the stock price goes up when the institutional investor buys a stock, while it goes down when the individual investor buys one.

This study examined visitors' perceptions and attitudes about establishing cable car in Mudeungsan Provincial Park (MPP). Data were collected from 401 respondents by a field questionnaire survey in MPP during the September of 2010. 61.7% of respondents opposed to establishing cable car in MPP while 20.6 percent supported it. Respondents showed high level of belief to possible consequences that establishing cable car will result in 'deterioration of ecosystem and natural landscape', 'crowding problem by increased number of visitors', 'disappearance of naturalness or previous nature experiences in MPP'. Respondents, however, presented low belief to 'positive effects on increasing economic income and local economic growth by attracting tourists'. 32.4 percent of the survey respondents evaluated the present MPP as a place of 'Nature Preservation Area (NPA)' and 10.5% as 'Developed Park Area (DPA)'. 48.8% of respondents answered that MPP should be managed as 'NPA' with only 2.5% as DPA. Respondents' socio-demographic characteristics (i.e., gender, age, education level, length of residence in Gwang-ju city), use patterns (number of visits to MPP or to Jungbong and surrounding areas), and normative place condition of MPP showed relationship with the overall support rates about establishing cable car. The results and their implications were discussed.

Objectives: This study aims to identify health status and health risks among female marriage immigrants to Korea and to provide a basis for public health strategies to address their health issues. Methods: The participants of the study were 3,069 immigrant wives. The health examination was conducted by the Korea Association of Health Promotion (KAHP) in 2008. The participants also completed self-administered questionnaires on demographic characteristics, health-related behaviors and mental health. Results: Patterns of immigrant women's health problems differed by age and country of origin. Behavior patterns also differed by their heritage, age, and years of residence in Korea. Generally Vietnamese women fell in lower ranges of disease prevalence and health risk factors in the participant group and Japanese women presented most healthy eating habits. Filipina women showed relatively high disease prevalence than any other group. Conclusion: Immigration to Korea by marriage is relatively a new phenomenon, thus continuing surveillance and research are needed to identify health risks, behavior patterns, and their relationships. Interventions and policies for the health of migrant wives, their children and families are required.

A survey was conducted to study the influence of socia-demographic factors on health-related behaviors. from June 1 to July 31, 1996. The study population was 1,903 adults in Kyongju City. A questionnaire method was used to collect data. Health-related behaviors included 24 items for men and 26 items for women. The followings are summaries of findings : The compliance of health promotion activities was higher when the age was older in men, when married, when having no religion and when the education level was higher than the other groups. And it was significantly higher when the income was lower in men and higher in women, in the residents living in apartment, in white collar workers, in the chronic ill people and when the body weight was lower than the other groups. Notable differences were found in the composition of health behavior factors for socio-demographic characteristics. Men used more tobacco, coffee and tea, salt and alcohol than women. However, the practice rates of regular exercise and physical examination were higher in men than women. On the other hand, the practice rates of fruit/vegetable intake, milk drinking and regular tooth brushing were higher in women than men. When the age was old, the amount of fruit/vegetable intake, the frequency of physician visit and health check-up, and regularity of meal were increased. When the income was high, the use rate of seat-belts, the amount of coffee, milk, fruit/vegetable and red meat intake were increased. The frequency of regular exercise. tooth brushing, health check-up, pap test and breast self examination were higher in the rich than the poor. When the education level was high, the frequency of regular exercise and tooth brushing, and the use rate of seat belts were increased, and the amount of alcohol consumption and salt intake were decreased. These findings suggest that socio-demographic factors are significantly associated with the patterns of health behaviors. In conclusion public health programs and individual counseling efforts should be multifaceted and behavior-specific to encourage to practice healthy life-style.

By using deterministic dynamic models, we observe the behavior of the foreign exchange rate of a small open economy with rational expectation formation and different restrictions on the international economic integrations. First, an economy connected to the world by purchasing power parity and uncovered interest parity is studied in the next section. In both sections, financial assets available in the economy are domestic money and bonds. Stocks are added as a financial instrument in the next section, and real capital accumulation is also taken into account. Furthermore, the economy concerned there is fairly autonomous, and not directly governed by either purchasing power parity or uncovered interest parity. The expectation formation used throughout the whole paper is complete perfect foresight, which is the certainty version of rational expectation and free from any forecast errors. It is found that upon monetary expansion the short run depreciation of the foreign exchange rate is a fairly robust result regardless of the degree of the international economic integration, while it is not true for fiscal expansion. The expectation on the long run state significantly affects the short run response of the exchange rate. All of our models postulate that the current account should be balanced eventually. As the result, the short run behavior of the exchange rate is affected by the expectation on the long run balance and may well be a blend of the traditional flow view and modem asset view. The initial overshooting of the exchange rate is easily observed even in the fairly autonomous economy Furthermore, the initial overshooting is not reduced over time, but augmented for some time before it is eventually eliminated. As long as we maintain rational expectaion, introducing time delay in the adjustment of the foreign goods price to the foreign exchange rate does not make much difference.

Objectives : The aim of this study was to evaluate the associations between vasomotor symptoms and factors such as sociodemographics, health behaviors, medical condition, depression, stress, anxiety, attitude toward menopause, and quality of life. Methods : We conducted a cross-sectional study in peri- and post-menopausal women enrolled by the Korean Association of Health Promotion. Subjects submitted self-report questionnaires about vasomotor symptoms and other clinical symptoms. Associations between vasomotor symptoms and clinical variables were analyzed using stepwise multiple regression analyses. Results : 1951 women completed self-report questionnaires and 1022 women were enrolled in the study. The prevalence of vasomotor symptoms in peri- and post-menopausal women was 63.9%. Variables showing significant differences between subjects with vasomotor symptoms and subjects without them were score of Beck Depression Inventory, Brief Encounter Psychosocial Instrument-Korean Version, proportions of clinically significant depression(Beck Depression Inventory ${\geq}16$), Menopausal rating scale, attitude towards menopause, the 4 subscales of World Health Organization Quality of Life-BREF(Physical health, psychological, social relationships, environment), and a History of Premenstrual syndrome/Premenstrual dysphoric disorder. Stepwise multiple regression analyses indicated that Beck Depression Inventory, Brief Encounter Psychosocial Instrument-Korean Version, Menopausal Rating Scale, and the Psychological subscale of World Health Organization Quality of Life -BREF show associations with vasomotor symptoms. Conclusions : Menopausal vasomotor symptoms are associated with various psychological factors, especially with depression. Midlife women suffering vasomotor symptoms should therefore be screened for depression. Future prospective studies where clinical subjects are diagnosed using structured interviews, focusing on the causal relationship between depression and vasomotor symptoms are necessary.
