The objective of this study was to examine job satisfaction status and its related factors among dietitians working in hospitals. A survey questionnaire was sent to dietitians working in tertiary, general, and convalescent hospitals in Korea. The study sample hospitals included all tertiary hospitals (n=43), and the sample of general hospitals (n=114) and convalescent hospitals (n=240) was randomly selected using a stratified sampling method. A total of 665 dietitians completed the survey questionnaire. The questionnaire included 27 job satisfaction questions on task, stability vision, working conditions, and relationship areas, and the questions on task improvement need. The job satisfaction scores in all four areas ranged from 2.53/5.00 to 3.89/5.00, implying generally low job satisfaction level in hospital dietitians. The job satisfaction levels in the convalescent hospital group were significantly lower compared to those in the tertiary and general hospital groups. Whereas job satisfaction levels of tertiary and convalescent hospital groups did not differ by number of beds, those of the general hospital group increased significantly with the number of beds for all four areas. Multivariate regression analysis results showed that hospital type was a significant predictor of job satisfaction level for all four areas. Job satisfaction of relationship area was also significantly affected by the number of beds, whereas that of working conditions was influenced by annual income and working experience. The study findings provide useful information in planning clinical dietitians' optimal supply outlook for the improvement of clinical nutrition services.

Hospital malnutrition could be caused by not completing the food served in the hospital. This has been a big problem since it delays the recovery of the patient and extends the length of hospital stay. The purpose of the study was to reduce the plate waste for the DM diet by performing several nutrition service improvement activities. The study was performed in a general hospital with 900 beds. A questionnaire survey was taken by 39 DM patients to obtain their aspect of the hospital foodservice systems and the quality of the meals at the beginning of the study. The amounts of foods served in the hospital kitchen and returned were measured by weights. After the improvement activities, the measurement of the plate waste was performed again for comparison. The average percentage of plate waste for the DM diet was 23.2%. The survey showed no difference by sex, age or duration of admission in plate waste. However, this food wastage percentage showed differences between the patients having a chance to get information about the diet therapy (12.21%) and not having one (26.06%) (p < 0.05). Using a five-point Likert-type scale, the quality of food by its taste was 2.49 (1: very poor, 5: excellent), the temperature score was 3.56 (1: very poor, 5: excellent), and the amount of food served score was 2.95 (1: very poor, 5: excellent), and the preference score was 3.13 (1: very dislike, 5: very like). Nutritional care improving activities were performed by adjusting seasonings, developing new menus, and standardizing cooking methods in order to increase the satisfaction of meal quality. The dietitian's inpatients care protocol was adjusted to expand the nutritional counseling chance for the DM patients. After the improvement activities, the average plate waste was reduced to 14.6%, and the satisfaction of food taste and preference increased to 3.21 (p < 0.001), and 3.36 (p < 0.05) correspondingly. The result shows that, for therapeutic diet patients, food intake could be increased by improving the food service satisfaction by controlling the meal quality and clinical nutritional service activities.

Dietary therapy is a basic and emphasized treatment for diabetes. Several clinical studies have shown that diet can play a major role in preventing and managing diabetes. The purposes of this study were to evaluate the dietary behavior and to find solutions to barriers of diabetes mellitus patients. From February to July in 2007, questionnaires were distributed to one hundred and ten patients who were diagnosed DM by physicians and excluded first coming out-patients. One hundred and three data were used for statistical analysis using SPSS/Win 12.0. The main results of this study included the following: To measure dietary behaviors and barriers, a five point scale was used with the following labels: 'strongly yes', 'yes', 'fair', 'no', 'strongly no'. Thirteen dietary behaviors related to diabetes were grouped into the following 4 factors using factor analysis; 'taste control factor', 'blood glucose influence factor', 'practice volition factor', and 'exercise factor'. The mean scores of 4 factors were 3.88, 3.48, 3.55, 3.21, respectively. The 'taste control behaviors' score of subjects who had practiced diet therapy(4.00) was higher than those who had not practiced diet therapy(P<0.05). The 'blood glucose influence behaviors' score of subjects who had nutrition education(3.59) was higher than those who had no nutrition education(P<0.05) and subjects who had practiced diet therapy showed higher score(3.59) than those who had not practiced diet therapy(P<0.05). 'Exercise behaviors score' of subjects who were over 60(3.59) was the lowest(P<0.05). Subjects who had nutrition education showed higher 'exercise behaviors' scores(3.38) than those who had no nutrition education(P<0.05). Subjects who had practiced diet therapy showed higher 'practice volition behaviors' scores(3.72) than those who had not practiced diet therapy(P<0.001). Subjects who were over weight showed the highest 'practice volition behaviors' scores(3.78) concerning BMI(P<0.05). In conclusion, this study expected that Nutrition educators(Dietitian) applied to patient effective nutrition education and counseling through evaluation of Dietary behaviors and barriers considered management types and ecological factors of diabetes patients. Also diabetic patients were easy to change dietary habits because they formed behaviors through education and counsel and there were positive effects in their blood glucose control through removing barriers related to dietary therapy.

Few studies investigated the effects of nutrition education and exercises in women with osteopenia. This study examined the relationship between changes in dietary intakes and changes in indicators related to bone health in postmenopausal women with osteopenia (-2.5 ${\leq}$ T-score ${\leq}$ 1) after a 12-week intervention. Thirty-one postmenopausal women aged > 50 years residing in Seoul were recruited and participated in nutritional education regarding bone health and general nutrition practices and aerobic exercises (three times a week; 60 min per session). Twenty-five subjects completed the study and were eligible for the analysis. Bone mineral density (BMD) at femoral neck was measured by dual energy x-ray absorptiometry. Serum calcium, osteocalcin, and intact parathyroid hormone (PTH) were also measured. Dietary intake was estimated by using a one-day 24 recall by a clinical dietitian. After 12 weeks, meat consumption increased (P = 0.028) but vegetable intake decreased (P = 0.005). Intakes of animal protein (P = 0.024), vitamin B1 (P = 0.012) and vitamin $B_2$ (P = 0.047) increased, and sodium intake decreased (P = 0.033). Intact PTH (P = 0.002) decreased and osteocalcin (P = 0.000) increased, however, BMD decreased (P = 0.000). Changes in mushroom consumption were positively correlated with femoral neck BMD (r = 0.673, P = 0.003). Changes in animal iron intake were negatively correlated with intact PTH (r = -0.488, P = 0.013) but were positively correlated with osteocalcin (r = 0.541, P = 0.005). These results suggested that the association between animal iron intake and biochemical markers of bone turnover may play an important role in bone metabolism. Further studies are needed to shed light on complicated mechanisms of diet, hormonal levels of bone metabolism, and bone density.

A case-controlled, 12 week follow-up, study was designed to investigate the effect of dietician-delivered medical nutrition therapy (MNT) on the nutritional status and quality of life in hemodialysis patients. Subjects were recruited at Kyung-Hee Medical Center and were randomly assigned to two groups : the control and the MNT group. The MNT group received individualized MNT for 12 weeks. The results were as follows: 1) The mean ages of the control (n = 20) and MNT (n = 24) groups were 50.6 $\pm$ 14.8 and 45.7 $\pm$ 14.0 years, and the mean durations of dialysis were 2.3 $\pm$ 2.3 and 1.7 $\pm$ 1.9 years, respectively. The interdialysis weight gain of the subjects was higher than that recommended. 2) The indicators of the subjects nutritional status showed that S to 25% of the subjects had some degree of malnutrition, with most of them in the mild malnutrition category. 3) After 12 weeks of the experiment, the percentage of the ideal body weight (% IBW) of the control group decreased, but that of the MNT group increased. Changes in other anthropometric parameters in both groups during the study period were not significantly different. 4) At the beginning of the study, the 54% of the MNT group consumed more than 28 kcal/kg body weight/day and 50% consumed more than 1.0g protein/kg body weight/day. However, these percentages rose to 71% and 75%, respectively, after 12 weeks of the individualized MNT. 5) The serum albumin and blood urea nitrogen (BUN) levels of the control group decreased significantly artier 12 weeks of the experiment, while those of the MNT group did not change. 6) After 12 weeks of individualized MNT, the mean score of nutrition knowledge and total mean score of quality of life (QL) of the MNT group were significantly higher than that of th\ulcorner control group. Body pain and social functioning scores of the MNT group were significantly higher than those of the control group. The positive effect of individualized MNT on the hemodialysis patients consisted of their improved nutritional status, nutritional knowledge, and the quality of life. These results suggest that individualized MNT continuously performed by a dietitian can be helpful for hemodialysis patients. However, larger and longer term studies are needed to confirm these positive effects of MNT. In addition, the development of nutritional education programs for MNT is needed to increase the positive impact of MNT.

Objectives: This study was conducted to examine the preferences and needs of typical Korean females adults for food and nutrition information provided by the mass media. Methods: A total of 343 females (77 in their 20s, 85 in their 30s, 88 in their 40s and 93 in their 50s) residing in the Seoul/Gyeonggido area was surveyed on general characteristics, main sources of food and nutrition information and needs for sources and contents of nutrition information. Results: The survey showed that typical Korean females obtained knowledge of food and nutrition mainly through the Internet (30.4%) and broadcasting (29.0%). Typical Korean females were interested in 'dietary management for weight control' (21.9%), 'the prevention and treatment of disease' (20.0%), 'food safety' (16.8%), 'proper dietary habits' (14.6%), 'cookery' (11.8%), 'functional foods' (9.6%), 'restaurant details' (3.5%) and 'life-cycle-specific dietary guideline' (1.6%). Needs for food and nutrition program forms on TV were 'educational programs' (34.3%), 'documentaries' (20.8), 'expert lecture-style' (13.0%), 'entertainment programs' (11.9%), 'expert conversation' (11.4%), 'news-style' (4.6%) and 'public campaign advertisements' (4.0%). On the Internet, 38.6% of the respondents preferred to get information provided by food and nutrition-related institutions (38.6%) while 26.1% preferred webtoons for nutritional information. The favored forms in mobile applications were 'monitoring their diets' (29.5%), 'data-based texts information' (21.4%), 'experts feedback' (20.6%), 'communities' (15.1%) and 'games' (13.1%). The rates of the preference to obtain information from experts such as nutritionists and dietitians and doctorsor dietitian turned reporters increased markedly with older ages. Conclusions: Since the mass media is a main source of food and nutrition information for the general public, the effectiveness and accuracy of the information provided should be enhanced by taking the needs of the public into account. The quality of information should be improved by involving more nutrition experts.

Atopic dennatitis (AD) is one of the major public health problem. It has been reported that the prevalence of AD in children and adults are 10-20% and 1-3%, respectively. Westernization of food habits, urbanization, and environmental pollution are contributing factors toward the recent rise in prevalence. Excessive dietary restriction leads to chronic malnutrition in atopic dermatitis patients. The purpose of this study was to investigate the effects of medical nutrition therapy (MNT) on quality of diet and blood immune parameters in atopic dermatitis patients. The 19 atopic dermatitis patients (7 men and 12 women) admitted to K University Medical Center were studied. During the 12 weeks of intervention, the subjects were given MNT by a dietitian for 30-45 minutes every other week. MNT was comprised with general dietary therapy, intake of balanced meals, emphasis on n-3 fatty acid contents in foods, and food allergies. Anthropometric and dietary assessment and blood analysis were taken at baseline and after 12 weeks of MNT. After 12 weeks of MNT, the subjects' dietary qualities, including dietary diversity score (DDS), meal balance score (MBS) and dietary variety score (DVS) were significantly increased (p < 0.05). According to significantly increased intake of EPA and DHA, dietary n-6/n-3 fatty acid ratio decreased to the recommended level for the atopic dermatitis patients (p < 0.05). These changes of dietary fatty acid consumption were reflected erythrocyte fatty acid composition. After 12 weeks of MNT, serum levels of IgE and IL-4 levels were significantly decreased, however, the levers of INF-$\{gamma}$, WBC, lymphocyte and TLC were not changed. As a conclusion, the individualized MNT improved the quality of diet in atopic dermatitis patients thereby influenced RBC fatty acid composition and IgE and IL-4 levels.
