Despite the importance of prenatal nutrition, many studies find inadequate calcium intake among pregnant women. The purpose of this study was to investigate the value of the Theory of Planned Behavior in explaining the intentions and the actual consumption of milk among pregnant women participating in or eligible for WIC. A cross-sectional survey was conducted to collect information regarding attitudes, subjective norms, perceived control, milk allocation within the family, intentions and consumption of milk. The survey questionnaire was developed using open-ended questions and interviews with 112 pregnant women. One-hundred-eighty women recruited from prenatal clinics completed the survey questionnaire. Multiple regression was used separately to investigate the association of factors to intentions and to the consu-mption of milk, as proposed in the theory. Milk allocation within the family was used as an exploratory variable to explain milk consumption. Study findings revealed that all three factors, attitudes, subjective norms and perceived control contributed to the model in explaining intentions (explained variance : 36.2%), with perceived control being most important. For milk consumption, intentions and perceived control were related significantly to actual consumption, while milk allocation within the family was not (explained variance : 44.6%). These findings suggest that perceived control is important in understanding both intentions and milk consumption, providing empirical evidence for the Theory of Planned Behavior. With respect to the role of perceived control, more strong evidence was provided in explaining intentions. Findings suggest that educational interventions to increase milk consumption among pregnant women should incorporate strategies to enhance the perception of control, and to strengthen positive attitudes and to elicit social support from significant other.

During the month of October, 1990, 676 practicing physicians in Taegu City were surveyed by mail questionnaires about their general characteristics and the reasons why they chose Taegu as a practice location and 331 out of them responded completely. Collected data were analyzed to provide basic reference data for future health manpower policy which intends to solve the problem of geographical maldistribution of physicians, The major findings are as follows: For the question asking why Taegu area is favored, following lists are as the order of their magnitude of the reasons replied by more than 20% of the respondents: 1) Taegu is a foundation of life until now(81.3%) 2) Better educational environments are available for their offsprings(73.7%) 3) They can have intimate relationship with acquaintances or friends sharing same or similar interests(61.0%) 4) Due to characteristics of their specialty, metropolitan seems to fit better(52.0%), 5) They graduated from the medical school in Taegu(49.8%) 6) Never thought of selecting practice location in other area than Taegu without any specific reasons(45.9%) 7) Intelligent communications are available with other physicians(39.9%) 8) More opportunities to participate in social life, such as medical, or alumni association etc., can be given(33.2%) 9) No specific knowledge or relationships with other area are available(32.6%) 10) They finished internship or residency training in Taegu area(31.4%) 11) Facilitation of transferring patients including emergent patients can be obtained (30.8%) 12) Continuing medical educational programs are available(29.9%) 13) Sufficient medical demands are provided because of the large population(28.1%) 14) More chances to be grown up as a medical professionals can be achieved(25.7%) 15) More leizure time can be utilized for cultural activities(23.9%) 16) They had experiences to work in hospitals or facilities in Taegu area(23.3%) 17) Medical facilities of fellow physicians or alumni can be used(20.5%) In addition, 37% of female physicians answered that their spouse strongly influenced them to choose Taegu, and 33.3% of physicians with age of thirty replied that parents did so. Physicians of specialty in radiology, clinical pathology, anatomical pathology, and anesthesiology considered that patients from other hospitals and medical facilities would be referred often to them and that less competition seemed to be expected in their specialty (30.8%). In contrast, general practitioners anticipated that larger population would increase the medical demand(62.5%). 28.6% of medical practitioners who graduated medical schools in other are than Taegu and 22.0% of medical practitioners who were trained in hospitals of other area than Taegu were influenced to choose Taegu by their spouses. In consideration of above findings, we may conclude that long term and rational manpower policies should be implemented to solve the problem of geographical maldistribution of physicians as well as short term physician-inducing policies, and they have to be incorporated with equitable community development.

In recent years, with the development of computers and electronics, electronics and communication technology in a growing and each part is dependent on the cross-referencing makes all electronic equipment is obsolete due to direct or indirect damage EMP. Korea and the impending standoff North Korea has a considerable level of technologies related to the EMP, EMP weapons you already have or in a few years, the development of EMP weapons will complete. North Korea launched a long-range missile and conducted a nuclear test on several occasions immediately after, when I saw the high-altitude nuclear blackmail has been strengthening the outright offensive nuclear EMP attacks at any time and practical significance for the EMP will need offensive skills would improve. At this point you can predict the damage situation of Korea's security reality that satisfy the need, more than anything else to build a protective system of the EMP. The scale of the damage that unforeseen but significant military damage and socio-economic damage and fatalities when I looked into the situation which started out as a satellite communications systems and equipment to attack military and security systems and transportation, finance, national emergency system, such as the damage elsewhere. In General, there is no direct casualties reported, but EMP medical devices that rely on lethal damage to people who can show up. In addition, the State power system failure due to a power supply interruption would not have thought the damage would bring State highly dependent on domestic power generation of nuclear plants is a serious nuclear power plant accident in the event of a blackout phenomenon can lead to the plant's internal problems should see a forecast. First of all, a special expert Committee of the EMP, the demand for protective facilities and equipment and conduct an investigation, he takes fits into your budget is under strict criteria by configuring the contractors should be sifting through. He then created the Agency for verification of performance EMP protection after you have verified the performance of maintenance, maintenance, safety and security management, design and construction company organized and systematic process Guard facilities or secret communications equipment and perfect for the EMP, such as protective equipment maneuver system should take.

Leptin, as an adipocyte-derived hormone, is an important regulator of food intake and energy expenditure. In the cross-sectional study, leptin was shown to be positively related to body adiposity and metabolic disorders in adults. However, there were very few studies which reported the leptin as a predictor of weight gain over time. We examined whether serum leptin can be used as an indicator of the present and 1-year past weight status in very young children. First grade students from elementary schools in Gwacheon City were enrolled in the study since 2005. The study subjects(total 375 students; 195 boys and 180 girls) participated in the investigation of both 2005 and 2006. Physical examinations including height, weight, waist circumference were done. To examine the prevalence of obesity, obesity index was used. Serum leptin was measured, and their nutritional status was also evaluated based on 3-Day dietary records. Serum leptin levels were strongly positively related with the value of the present BMI and with the value of the BMI one year before. We found no association with leptin levels and amount of energy intake and macronutrient intake in this children population. Children were divided into three groups according to leptin tertiles. The highest leptin tertile group showed highest prevalence of obesity in year 2006 as well as in year 2005. Serum leptin levels can reflect the weight status now and as well as 1-year before. Possibly serum leptin levels can predict the weight gain of year later. Without an action against the obesity on children with high leptin level, those children would maintain the excess adiposity growth and progress into the obesity-related metabolic disorders. Further studies are needed to predict the obesity as early as possible and preventive system then after.

Purpose: This study examined the association between fruit and vegetable intake and mental health in Korean adolescents. Methods: This study used the data from the 2014-2017 Korea Youth Risk Behavior Survey, a national cross-sectional survey on 137,101 boys and 130,806 girls aged 12-18. Fruit and vegetable intake was assessed based on the frequency of consumption. The outcome variables were the perceived happiness, perceived stress, depressive symptom and suicidal ideation over the previous 12 months. Logistic regression models were used after adjusting for the demographic, life style and other dietary factors. Results: Only 34% and 29% of Korean adolescents consumed fruits more than 5 times/week and vegetables more than 2 times/day, respectively; whereas 37%, 25% and 12.2% of Korean adolescents had perceived stress, depressive symptom and suicidal ideation, respectively. After adjusting for the confounding variables, the greater consumption of fruit and vegetable were all associated with a higher odds of perceived happiness; the adjusted odds ratios (AORs) (95% CI) were 1.53 (1.46-1.60) in boys and 1.82 (1.73-1.90) in girls who consumed fruit ≥ 5 times/week, and 1.65 (1.54-1.76) in boys and 1.62 (1.51-1.72) in girls who consumed vegetable ≥ 2 times/day. In contrast, the consumption of fruit or vegetable were all significantly associated with a lower odds of perceived stress, depressive symptom, and suicidal ideation; the AOR (95% CI) were 0.70 (0.67-0.73), 0.88 (0.84-0.93), and 0.78 (0.73-0.83) in boys who consumed fruit 3-4 times/week, and 0.71 (0.67-0.76), 0.88 (0.81-0.94), and 0.68 (0.62-0.74) in boys who consumed vegetable 5-7 times/week. Similar associations of fruit or vegetable consumption with perceived stress, depressive symptom, or suicidal ideation were found in girls. Conclusion: These findings provide evidence that increasing fruit and vegetable intake is important for better mental health among adolescents.

In the age of globalization, effective and efficient corporate management is becoming more important as domestic and international business circumstances changes. In the middle of endless changes in business circumstances, fast reaction to customers and market, and offering customized goods and service became essential. In this respect, CRM designed to utilize customer information scientifically and systematically, has become an essential system and marketing strategy to enhance corporate competitiveness. CRM has placed the importance of customers in the front of marketing and has focused every process and business minds on customers. Recent change in the market and the trend of establishing and introducing CRM system has lead us to concentrate on the introduction of CRM in the financial institutions. This study searched for several views about CRM in academic and industrial papers. Through theoretical approach on CRM, the background of the introduction of CRM, the purpose of CRM, the characteristic and application of CRM, and the expected effect of CRM will be discussed. This study is focused on financial institutions where CRM is widely used. And through documents about examples of the introduction of CRM, the status of the establishment of domestic CRM and the necessity and trend of CRM will be discussed. Also the problem of CRM in the financial institutions and the improvement of CRM in domestic banks will be analyzed. When discussing CRM in the financial area, customers are the main source of corporate profit and through relationship management with the customers enhancing loyalty and maximizing profit can be obtained. Especially in CRM in financial institutions, maintaining existing customers makes higher profit ratio, so repurchasing and cross selling becomes important for obtaining lifetime value of existing customers who contribute to most of the profit of corporations. As a result, CRM should be completely customer oriented. CRM in financial institutions is not merely marketing work, but organizational competence which is made up of standardized work process through total process integration inside the corporation. Corporations which plan to introduce CRM should analyze the characteristics and conditions of corporations and establish purpose and strategy of CRM. And they need long term view to find out the factors which best fit for the introduction of CRM. To enable this, strategy composed of daily marketing activity and CRM concept is necessary. Also continued improvement through drill and training for operating organization should be followed to maintain CRM well. And corporate culture must settle customer as the center of corporate value. The race for introducing and improving CRM has already begun. CRM should not be regarded as a choice. It should be accepted as something essential. In this reality financial institutions should solve subdivision problem of customers and necessity of customers with the mind of 'customer's profit is my profit'. Customer focused management should not be emphasized only by words. Efforts like viewing from the customer's point must be nurtured to provide methods to help customers. That is, we should not just follow what is done in foreign countries. We should solve the problem of our customers according to the situation of our country, our industry, our corporation. Then we can gain the trust of customers, and the value derived from the customers will become the background of CRM which will lead the corporation to success.

Concerning the risk factors of the outbreak of a fire in a traditional market, most of those markets are located in downtown areas or residential areas; thus, although their location may be favorable in terms of marketability, they face a potential risk in that a fire may develop into a large blaze owing to poor environment or the absence of facilities prepared for disaster during a fire. Moreover, as many people are densely poised in the markets, it is very probable that a fire may occur owing to the excessive use of heaters in the winter as well as the reckless use of electric and gas facilities. It seems that traditional markets encounter difficulty being insured against fire, because of their vulnerability and that the vast majority of small-scale sellers are likely to suffer mental anguish and tremendous physical injury in case of a fire. However, most of those sellers in the traditional markets are hand-to-mouth sellers, and they lack awareness of safety concerns and have insufficient experience in safe facility management. As small-scale sellers constitute the majority in the traditional market, the subscription rate of fire insurance in most of the traditional markets is low for the reasons of their needy circumstances and their financial burden. Statistically, the subscription by street vendors is non-existent; therefore, these vendors have a fairly limited access to indemnification after fire damage. Because of these problems, this study's purpose is to identify the current level of insurance subscription by these markets, which are exposed to poor facilities and vulnerability to fire. In order to fix this, it appears that shop owners and consumers will have to band together. For this study, we executed a fire policyholder fact-finding mission at traditional markets with approximately 108 and 981 stores. The research method was executed by an investigation using one-on-one individual interviews using a questionnaire. The contents investigated current insurance subscriptions. The method of analysis looked at the difference of insured amount according to volume size through cross-tabulation of the difference of insured amount by possession form, difference of insured amount by market form, difference of insured amount by category of business, difference of insured amount by market size, etc. Furthermore, the study should be used to propose solutions for problems through theoretical review with the use of a literature research, because the field case study was through interviews with the persons concerned, and the survey of the current insurance subscriptions by traditional market shopkeepers. The traditional market would generally have difficulty affording fire insurance. Fire insurance subscription rates of most of the market proved to be inactive, because of the economic burden of payment. Lack of funds is thought to be the main factor that causes a lack of realization about the necessity of fire insurance. In addition to expensive insurance premiums, sometimes, the companies' valuation of the businesses is lower than their actual valuations, and they do not pay out enough during a claim. The research presents an improvement plan that, when presented at the traditional markets, may strengthen their ability to procure fire insurance through the help of the central government. Researchers connected with the traditional market mainly accomplish the initial research. However, although this research has its limitations, it offers considerable benefits. For future researchers, I would suggest looking at several regions for comparison.

To evaluate the ischemic heart disease risk factors and analysis on the its relationship between risk factors and ischemic heart disease on EKG findings in a rural area, We conducted cross-sectional health screening test for 1304 persons aged over 30 years. Blood pressure, total cholesterol, HDL cholesterol, fasting blood glucose, BMI and Waist/hip ratio, smoking data and EKG data were collected. Hypertension was classified by the sixth report of the Joint National Committee on Detection, Evaluation, and Treatment of High Blood Pressure and the cutpoints of hyperlipidemia was used National Cholesterol Education Program. The cutpoint of hyperglycemia was used National Diabetes Data Group and those for obese was 30%. The results obtained were as follows; 1. Prevalence of definitive hypertension was 41.2% in males and 41.6% in females. The prevalence of hypertension showed Increasing tendency according to age increase(p<0.05). 2. Prevalence of hyperlipidemia was 20.6% in males and 20.4% in female. In females prevalence of hyperlipidemia showed increasing tendency according to age increase(p<0.001). 3. Prevalence of obese was 23.4% in males and 28.8% in females. Upper body type was predominant in females, but lower body type was predominant in males. 4. Prevalence of hyperglycemia was 11.0% in males and 12.1% in females. The prevalence of hyperglycemia showed increasing tendency according to age increase(p<0.01). 5. The smoking rate was 63.7% in males and 2.6% in females. 6. On the EKG findings, the prevalence of myocardial ischemia and myocardial infarction was 6.7% in males and 7.5% in females. 7. The prevalence of Ischemic heart disease was higher in hypertension than normal in females and higher in obese than normal in males. In males and females the prevalence of ischemic heart disease was higher in hyperglycemia than normal and higher in upper body type than lower body type. But there is no statistical association among them.

This study examines the expiration-day effects of stock index futures and options in the Korean stock market. The so-called 'expiration-day effects', which are the abnormal stock price movements on derivatives expiration days, arise mainly from cash settlement. Index arbitragers have to bear the risk of their positions unless they liquidate their index stocks on the expiration day. If many arbitragers execute large buy or sell orders on the expiration day, abnormal trading volumes are likely to be observed. If a lot of arbitragers unwind positions in the same direction, temporary trading imbalances induce abnormal stock market volatility. By contrast, if some information arrives at market, the abnormal trading activity must be considered a normal process of price discovery. Stoll and Whaley(1987) investigated the aggregate price and volume effects of the S&P 500 index on the expiration day. In a related study, Stoll and Whaley(1990) found a similarity between the price behavior of stocks that are subject to program trading and of the stocks that are not. Thus far, there have been few studies about the expiration-day effects in the Korean stock market. While previous Korean studies use the KOSPI 200 index data, we analyze the price and trading volume behavior of individual stocks as well as the index. Analyzing individual stocks is important for two reasons. First, stock index is a market average. Consequently, it cannot reflect the behavior of many individual stocks. For example, if the expiration-day effects are mainly related to a specific group, it cannot be said that the expiration of derivatives itself destabilizes the stock market. Analyzing individual stocks enables us to investigate the scope of the expiration-day effects. Second, we can find the relationship between the firm characteristics and the expiration-day effects. For example, if the expiration-day effects exist in large stocks not belonging to the KOSPI 200 index, program trading may not be related to the expiration-day effects. The examination of individual stocks has led us to the cause of the expiration-day effects. Using the intraday data during the period May 3, 1996 through December 30, 2003, we first examine the price and volume effects of the KOSPI 200 and NON-KOSPI 200 index following the Stoll and Whaley(1987) methodology. We calculate the NON-KOSPI 200 index by using the returns and market capitalization of the KOSPI and KOSPI 200 index. In individual stocks, we divide KOSPI 200 stocks by size into three groups and match NON-KOSPI 200 stocks with KOSPI 200 stocks having the closest firm characteristics. We compare KOSPI 200 stocks with NON-KOSPI 200 stocks. To test whether the expiration-day effects are related to order imbalances or new information, we check price reversals on the next day. Finally, we perform a cross-sectional regression analysis to elaborate on the impact of the firm characteristics on price reversals. The main results seem to support the expiration-day effects, especially on stock index futures expiration days. The price behavior of stocks that are subject to program trading is shown to have price effects, abnormal return volatility, and large volumes during the last half hour of trading on the expiration day. Return reversals are also found in the KOSPI 200 index and stocks. However, there is no evidence of abnormal trading volume, or price reversals in the NON-KOSPI 200 index and stocks. The expiration-day effects are proportional to the size of stocks and the nearness to the settlement time. Since program trading is often said to be concentrated in high capitalization stocks, these results imply that the expiration-day effects seem to be associated with program trading and the settlement price determination procedure. In summary, the expiration-day effects in the Korean stock market do not exist in all stocks, but in large capitalization stocks belonging to the KOSPI 200 index. Additionally, the expiration-day effects in the Korean stock market are generally due, not to information, but to trading imbalances.

This is a cross-sectional study to evaluate the relationships between physical fitness, leisure time physical activity, and serum lipid levels in middle-aged male workers. Physical fitness was measured by a step test score, and leisure time physical activity was self-reported on a questionnaire. Serum total cholesterol was negatively related to physical fitness(r=-0.27), and positively to obesity index(r=0.27). But leisure time physical activity was related to total cholesterol negatively(r=-0.20) only in subjects whose total cholesterol levels were above 170mg/dl. High density lipoprotein(HDL) cholesterol was positively related to physical fitness(r=0.15), negatively to obestiy index(r=-0.22), and positively to weekly alcohol consumption(r=0.14). Total cholesterol/HDL cholesterol ratio was related to physical fitness(r=-0.23), obesity index(r=0.32), total cigarette index (r=0.13), weekly alcohol consumption(r=-0.13), and vegetable preference(r=0.13). Physical fitness was also related to leisure time physical activity(r=0.19) and obesity index(r=-0.18). In multiple linear regression models, physical fitness(beta=-0.23) and obesity index(beta=0.18) were significantly associated with total cholesterol, obesity index(beta=-0.25) with HDLcholesterol, and obesity index(beta=0.30), physical fitness(beta=-0.16) and vegetable preference (beta=0.14) with total cholesterol/HDL cholesterol ratio. In conclusion, as physical fitness has a stronger relationship with serum lipid levels than leisure time physical activity, and the association between physical fitness and leisure time physical activity is modest, physical fitness should be added as an important variable in addition to activity in future epidemiologic studies.
