Although a variety of agents have been introduced for the treatment of hypertension, the ideal drug has not yet been discovered. However, among the agents available, prazosin hydrochloride (Minipress(R)) appears to be accepted by the majority of physicians as it lowers blood pressure effectively with relatively low incidence of side effects. It has been considered that the hypotensive effect of prazosin is a result of peripheral vasodilation due to direct relaxation of vascular smooth muscle and blockade of alpha-adrenergic receptors in the arteriolar smooth muscle. Following the development of prazosin. many trials have been designed to potentiate its hypotensive effect by the combination with other agent, especially thiazide or beta blocker. Minizide(R), a preparation that thiazide is added to prazosin, is an example. The antihypertensive effect of Minizide(R) was evaluated in 30 hypertensive subjecs. The results were as follows; 1. The systolic and diastolic blood pressure were effectively lowered in both supine and standing position with the overall response rate of 86.7% as judged to be responsive in one that lost systolic pressure more than 15 mmHg and distolic pressure 10 mmhg. Among 30 cases 18 cases could be maintained with their diastolic pressure below 90 mmHg and 24 cases with their diastolic pressure below 100 mmHg by the end of 8th week of treatment with the daily dose of minizide(R) from a half tablet to two tablets. 2. During the period of 8 weeks, troublesome postural hypotension was not observed in any case. The pulse rate was not accelerated significantly by Minizide(R) treatment. 3. Minimal side effects were recorded in 5 cases; two of mild nausea, one of slight dizziness, one of minimal gastrointestinal irritation symptom and one of mild glucosuria. neither of them hindered the authors from finding the study.

PURPOSE: The purpose of the study was to identify teacher's knowledge about sodium, dietary behaviors related to sodium, attitudes towards a low-salt diet, and meal attitude guidance as well as examine the relationship between these variables. METHODS: The participants were 351 teachers at an elementary school in the Jeonbuk area. The data were analyzed using ANOVA, Duncan test, and Pearson correlation coefficients with SPSS v. 20.0. RESULTS: The score for teachers' knowledge about sodium was 12.92 points of a possible 16, the score for dietary behavior related to sodium was 46.85 points of a possible 70, and the score for attitude towards a low-salt diet was 33.63 points of a possible 50. Their score for meal attitude guidance was 59.95 points of a possible 80. The knowledge showed significant differences by hypertension drug (p < 0.05) and stress level (p < 0.05). The dietary behavior of sodium use showed significant differences by gender (p < 0.01), work experience (p < 0.05), BMI (p < 0.01), drinking (p < 0.05), concern about health (p < 0.05), and stress level (p < 0.05). The attitude towards a low-salt diet showed significant differences by gender (p < 0.05), marital status (p < 0.05), work experience (p < 0.05), drinking (p < 0.05), concern about health (p < 0.001), and stress level (p < 0.05). Meal attitude guidance showed a significant difference by marital status (p < 0.001), age (p < 0.001), work experience (p < 0.001), drinking (p < 0.01), regularity of health checkup (p < 0.001), concern about health (p < 0.001), and stress level (p < 0.05). There was a low positive correlation between knowledge about sodium and dietary behavior related to sodium as well as between dietary behavior related to sodium and attitudes towards a low-salt diet. Attitudes towards a low-salt diet showed a positive correlation with meal attitude guidance. CONCLUSION: Therefore, it is necessary to consider educational programs on increasing knowledge and attitudes towards a low-salt diet in teachers for improvement of meal attitude guidance activities for students.

PURPOSE: The purpose of the study was to evaluate the status of events and importance-performance analysis (IPA) between industry and school foodservices. METHODS: The study subjects were dietitians in industry foodservices (n = 73) and nutrition teachers in school foodservices (n = 135) in the Jeonbuk area. Demographic characteristics, status of events, and problems of implementing events were assessed using a self-administered questionnaire. RESULTS: Approximately 67% of industry foodservices had implemented an event a month, whereas 40.7% of school foodservices did not implement events for students. The type of events that industry and school foodservices had implemented most frequently were Sambok event, Dongji event, Daeboreum event, Spring-Namul event, and Chuseok event. The industry foodservices had significantly higher average scores for performance of events than those of the school foodservices (p < 0.001). In the Importance-Performance Analysis (IPA), high importance and high performance (A area: doing great) in industry foodservices were seasonal events, traditional festival day events, anniversary events, traditional seasonal events, and personal memory events, whereas in school foodservices were traditional festival day events, traditional seasonal events, school events, and environment events. CONCLUSION: These results showed that events are important for the increase in customer satisfaction. Therefore, it is necessary to consider educational programs on event implementation for dietitians and employees in industry and school foodservices.

PURPOSE: The purpose of the study was to evaluate the status of safety accidents and importance-performance analysis (IPA) between regular and non-regular employees in industry foodservices. METHODS: The participants were regular employees (n = 119) and non-regular employees (n = 163) in industry foodservices in the Jeonbuk area. Demographic characteristics, status of safety accidents, safety education, and importance and performance status were assessed using a self-administered questionnaire. RESULTS: Approximately 66.4% of regular employees and 53.4% of non-regular employees experienced safety accidents (p < 0.05). Types of safety accidents of regular and non-regular employees were mostly burns, and causes were mostly from their own negligence. Approximately 98.3% of regular employees and 95.1% of non-regular employees experienced safety education. Approximately 88.9% of regular employees and 96.8% of non-regular employees received safety education from dietitians. Approximately 41.9% of regular employees and 50.0% of non-regular employees had difficulty applying the contents of safety education due to lack of time during work. As a result of IPA, regular and non-regular employees were aware of the importance of the following and performed them well: ‘Clean the floor of the work place’, ‘Arrange in the work area’, ‘Wear safety shoes’, ‘Check for heater cord’, and ‘Safety cooking when using oil’. On the other hand, they were not aware of the importance of the following and performed them insufficiently: ‘Check for the MSDS’, ‘Aware of chemical signs’, ‘Wear protection gloves etc.’, ‘Do stretching exercise’, and ‘Using ancillary tools’. CONCLUSION: Therefore, it is necessary to improve the consciousness of dietitians for effective application of safety education contents, development of contents, especially MSDS, and related things.

PURPOSE: To assess the efficacy of ancillary CT findings other than the obstructive lesion per se for the differential diagnosis of extrahepatic biliary obstruction. MATERIALS AND METHODS:CT findings of 49 patients with extrahepatic bile duct obstruction(22 benign and 27 malignant lesions) were assessed with emphasis on the patterns of ductal dilatation, contrast enhancement, and diffuse thickening of the extrahepatic ductal wall. Degree of central and peripheral intrahepratic ductal dilatation was graded by comparing with the adjacent portal radicles and hepatic parenchymal thickeness. RESULTS: Diffuse circumferential thickening and contrast enhancement of the extrahepatic ductal wall were more frequent in benign cases, but only thickening was statistically significant(p < 0.01). Peripheral intrahepatic ducts were more severely dilated by malignant causes(p < 0.01). With the same degrees of extrahepatic and central ductal dilatations, peripheral intrahepatic ducts were more severely dilated in malignant than in benign cases. CONCLUSION: These results may help to interpret the CT findings of extrahepatic biliary obstruction, particularly when the cause of biliary obstruction is uncertain.

Purpose: This study was undertaken to identify the alcohol drinking status of industrial workers, their health care practice, and dietary behavior, as well as their nutrient intake. Methods: In July 2019, 220 male subjects working in the Chungnam area were enrolled in the study. Their alcohol drinking status was evaluated by applying the Alcohol Use Disorder Identification-K (AUDIT-K) system. Demographic characteristics, status of health care practice, and dietary behaviors were assessed using a self-administered questionnaire;nutrient intakes were analyzed using 24-hour recalls. Data were analyzed by applying χ2 -test, ANOVA, Duncan test, and Pearson's correlation analysis with SPSS v. 25.0. Results: Workers were classified by their alcohol drinking status as ‘normal’ (84, 38.2%), ‘problem drinker’ (45, 20.5%), ‘alcohol dependence I’ (60, 27.3%), and ‘alcohol dependence II’ (31, 16.0%). The alcohol drinking status showed significant differences with age (p < 0.05), monthly income (p < 0.05), smoking status (p < 0.05), and need for weight control (p < 0.05). Moreover, increased alcohol intake resulted in significantly decreased levels of health care practice and dietary behaviors (p < 0.05, p < 0.01, respectively). The energy intake was highest in the ‘alcohol dependence I’ group, followed by ‘alcohol dependence II’, ‘problem drinker’, and ‘normal drinker’ (p < 0.05). Intakes of vitamin E, vitamin C, and niacin in the ‘alcohol dependence I’ group were found to be higher than the other groups (p < 0.05). A negative correlation was obtained between alcohol drinking status, health care practice, and dietary behaviors, whereas a positive correlation was determined between alcohol drinking status, energy and water intakes. Conclusion Considering these results, we conclude the necessity to consider nutritional and alcoholic education programs for improving the quality of work life of industrial workers, based on their alcohol drinking status.

PURPOSE: The purpose of the study was to examine the snack meal management for infants and toddlers and the demand for snack products according to mothers' sustainable dietary style in the Jeonbuk area. METHODS: The participants were 359 mothers in the Jeonbuk area. The data was analyzed using factor analysis, cluster analysis, analysis of variance, and χ²-tests with SPSS v. 25.0. According to the sustainable dietary style, the situation of providing snacks at home, the purchasing behavior for snack products, and the satisfaction and, demand for snack products were investigated. RESULTS: Using the K-clustering method, the sustainable dietary style of the subjects was categorized into 3 clusters. Cluster 1 was the family health-seeking group, cluster 2 was the sustainable dietary trend group, and cluster 3 was the sustainability-interested group. The frequency of snack intakes according to the cluster groups showed a significant difference (p < 0.001). Fruits were the snack item most frequently consumed by all the cluster groups. Approximately 92.8% of mothers had purchased snack products, and 95.2% of the subjects were satisfied with them (p < 0.05). The main reason for satisfaction with the snack products in all the cluster groups was the various kinds of products with considering the growth stage of children. Clusters 2 and 3 required the development of snack products using organic food materials, while cluster 1 required the snack products to be supplemented with various nutrients. CONCLUSION It is necessary to develop various snack products according to the sustainable dietary style and the needs of mothers so that these snacks can increase the satisfaction of mothers with the snack products and lead them to better snack purchasing behavior.

Purpose: This study examined the status of food allergy management and importance-performance analysis (IPA) between elementary, and middle and high school employees in school foodservice. Methods: The participants were employees in elementary (n = 171) and middle and high schools (n = 187) in the Jeonbuk area. The demographic characteristics, the status of food allergy management, food allergy education, and the importance and performance status were assessed using a self-administered questionnaire. Results: Approximately 55.0% of employees in elementary and 32.6% in middle and high schools recognized that the foods in menu tables induced allergies. Approximately 93.0% of employees in elementary and 85.0% in middle and high school thought that food allergy management was an important part of school foodservice because of the possibility of health emergencies. Elimination and replacement meals were provided more in middle and high schools than in elementary schools. Food allergy education from nutrition teachers had been given to 62.6% of employees in elementary and 50.3% in middle and high schools. To prevent food allergy accidents, 72.4% of employees in elementary schools and 65.2% in middle and high schools wanted more accurate information on students with food allergies. As a result of IPA, elementary, middle, and high school employees were aware of the importance and performed well: ‘Strict control of allergy-inducing foods because of cross-contamination’. On the other hand, they were not aware of the importance and performed them insufficiently: ‘Know how to use epinephrine to prepare for emergencies’. Conclusion Therefore, it is necessary to improve the consciousness of nutrition teachers for the effective application of food allergy education, especially the recognition of allergy-inducing foods and emergency responsive ability.

PURPOSE: The purpose of the study was to identify women's osteoporosis knowledge, concerns about osteoporosis factors, and health behavior as well as to examine the relationship between these variables. METHODS: The participants were 394 women in the Jeonbuk area. The data were analyzed using a t-test, ANOVA, Duncan test, and hierarchical regression analysis with SPSS v. 24.0. RESULTS: The score for osteoporosis knowledge was 6.21 points out of a possible 12, the score for concern about osteoporosis factors was 26.50 points out of a possible 40. The score for the health behavior was 57.26 points out of a possible 85. The knowledge showed significant differences according age (p < 0.01), income (p < 0.05), education level (p < 0.01), drinking milk in childhood (p < 0.05), health interest (p < 0.05), and osteoporosis information (p < 0.01). The concern showed significant differences according to age (p < 0.001), income (p < 0.05), health interest (p < 0.001), osteoporosis information (p < 0.001), family history of osteoporosis (p < 0.05), and calcium medications (p < 0.001). The health behavior showed significant differences according to age (p < 0.001), income (p < 0.01), drinking milk in childhood (p < 0.05), health interest (p < 0.001), osteoporosis information (p < 0.01), and calcium medications (p < 0.01). Regression analysis showed that the concern about osteoporosis factors was the most influential variable on health behavior, followed by health interest of the subjects, age, and the osteoporosis knowledge. CONCLUSION: Therefore, it is necessary to consider educational programs on increasing interest in osteoporosis according to the age and health for improving the health behavior to prevent osteoporosis.
