Numerous novel marine natural products have been discovered and isolated from varied marine organisms by the diligent bio-prospectors over the past decades. An assessment of the current status of commercial development of these natural compounds indicates only minimal commercialization due to the lack of sustainable supply. To bridge the gaps between discovery and commercialization of these tantalizing bioactive compounds, marine bioprocess engineering is the key for its success. The problems, challenges and opportunities for marine bioprocess engineers are examined for the timely transformation of the discovery into commercial reality. Marine bioprocess engineers will find it the most rewarding practice of their expertise in diving into the ocean.

The purpose of this study was to investigate the effects that body composition, nutrient intake, and biochemical indices have on skin status, as well as their associations with skin health status, by assessing 44 female university students. The subjects were classified into 3 groups according to skin sensitivity: sensitive skin (n=11), slightly sensitive skin (n=24), and normal skin (n=9). The study included anthropometric measurements and body composition analyses, dietary intake evaluations, blood chemical analyses, and skin health status assessments. Based on % body fat, the results indicated the subjects were moderately obese (29.6%). Obesity indices were not different among the groups, but the sensitive skin group tended to have higher skinfold thickness. Dry skin was determined as the skin type of all subjects. In the sensitive skin groups, U-zone and T-zone sebum were significantly lower (p<0.05), and spots were significantly higher (p<0.05) than in the normal skin group. In terms of nutrient intakes, the sensitive skin groups consumed significantly lower amounts of P and vitamins A and E (p<0.05). There were no significant differences in serum lipid fractions or total antioxidant status among the groups. In correlation coefficients analysis, skin elasticity had significant negative correlations with subscapular and midaxillary skinfold thickness, body protein, and body minerals (p<0.05). Wrinkling had positive correlations with triceps and thigh skinfold thickness (p<0.05). Skin evenness had negative correlations with energy intake, vitamins A, $B_1,\;B_2$, C, E, niacin, and zinc (p<0.05), as well as folate and P (p<0.01) and vitamin $B_6$ (p<0.001). A similar correlation tendency was observed for spots and nutrient intake, showing negative correlations with vitamins A, $B_6$, and E, as well as folate, Fe, and P. U-zone sebum showed significant positive correlations with serum levels of total cholesterol and triglycerides. From these findings, skin health status appears to be affected by both nutrient intake and body composition. Therefore, having a proper balance between dietary intake and body composition may influence skin health status in females with sensitive skin.

The purpose of this study was to examine the effect of temple food intake on health improvement. The survey was conducted from September to October 2013. The subjects in this study were 46 adults who participated in short-term 'Temple Stay' program. Every meal was prepared according to prearranged temple food menu, and it was provided to subjects for 4 weeks. Dietary intake, anthropometric measurements and biochemical parameter were measured and nutritional & health status were analyzed to find the effect of the program. Nutrients content of the temple food was sufficient to dietary reference intake while content of fat, fiber, vitamin A and calcium from the meal was significantly higher than the subjects' usual diet. Mean body weight, BMI and blood pressure (systolic and diastolic) related with obesity and hypertension decreased after the program. The index referring to liver function and cardiovascular disease risk such as serum ALT, ${\gamma}$-GTP, TG and LDL decreased while HDL increased thereby showing positive effect. The above results anticipate that temple foods with an affirmative effect in improving health status have a potential benefit that can be applied to general food service. Further detailed study might provide information in developing healthy diet for a corresponding clinical problem.

The prevalence of obesity in children has steadily risen during recent years in developed countries. Child obesity has become a major concern to health providers since it has grown to epidemic proportions over the past few decades. This study was conducted to investigate the biochemical status, dietary habits and life styles according to the obesity degree among obese children residing in the Gyungbuk area. The subjects were 148 elementary school students (boy 103, girl 45) and classified as mildly obese (n = 56), moderately obese (n = 61) and severely obese (n = 31) by the obesity index. The average body weight and height increased significantly according to the obesity degree (p < 0.05, p < 0.001). Serum cholesterol concentration came under the normal level in all groups. Serum AST activity increased according to the obesity degree but it was not significant. Serum ALT activity increased according to the obesity degree (p < 0.05). Dietary habit score was lower significantly according to the obesity degree (p < 0.01). Life style of the subjects was significantly different for the level of 'healthy state (p < 0.05)', 'body perception (p < 0.01)', 'watching TV and video (p < 0.05)', 'normal sleeping hour (p < 0.05)' and 'degree of stress (p < 0.05)' according to the obesity degree. A positive relationship between obesity index and blood pressure, ALT has been shown in the subjects. Obesity index and dietary habit scores were negatively associated. Therefore, these results suggest that a practical nutrition-exercise education program for the prevention of child obesity should be provided to elementary school children.

Purpose: The purpose of this study was to identify the nutritional status of elderly individuals according to their household types and to investigate the predictors of their nutritional status. Methods: This study, which was a descriptive research study, involved physical measurements, surveys, and biochemical tests in 87 elderly individuals living in the community. Using SPSS/Win 24.0, logistic regression analysis was performed to identify the general characteristics, blood pressure, body mass index (BMI), mini nutritional assessment (MNA) score, and biochemical indicators in elderly individuals according to the household type. Results: Elderly individuals living with family members had higher MNA scores than those of elderly individuals living alone, while showing lower levels of systolic blood pressure and fasting blood sugar. The results of the logistic regression analysis showed that the risk factors were MNA scores (odds ratio (OR)=1.81, 95% confidence interval (CI)=1.36-2.42), systolic blood pressure (OR=0.96, 95% CI=0.92-1.00), and fasting blood glucose (OR=0.94, 95% CI=0.90-0.99). Conclusion: It was confirmed that elderly individuals living alone need differentiated nutrition intervention, since the results showed that they had lower nutritional levels and improper nutritional management than that in elderly individuals living with family members.

The purpose of this study is to investigate the dietary intakes and nutritional status in total gastrectomized patients. We assessed the nutritional status by dietary intake, anthropometric data and biochemical data. And we also checked the subjective postprandial symptoms and gastrofiberscopy to detect the reflux esophagitis in 22 patients who were free of tumors for more than 1 year after total gastrectomy by the three different reconstruction methods(Loop esophagojejunostomy with A-loop tie/ Roux-en-Y esophagojejunostomy/Roux-en-Y esophagojejunostomy with Paulino pouch). Any patients were not in malnutrition status in respect to biochemical data. By assessing the dietary intake, the average daily calorie intake was 1848.2$\pm$440.2kcal, it was 105.9$\pm$23.8% of energy requirement. But there was weight loss in 21 patients of 22 patients after operation and the weight loss was 12.8% of preoperative weight(61.0$\pm$7.9 vs. 53.5$\pm$6.7kg, preoperatively vs. at the time of study). This may suggest that continuous nutritional care is necessary after total gastrectomy to promote sufficient calorie intake, keeping good nutritional state. There were no significant differences between the methods of reconstruction and dietary intakes or nutritional status. Endoscopic esophagitis was more frequently found in patients of loop esophagojejunostomy than any other reconstruction methods(p<0.001), but it didn't show any effect on the dietary intakes.

BACKGROUND/OBJECTIVES: Recent research regarding vitamin $B_6$ status including biochemical index is limited. Thus, this study estimated intakes and major food sources of vitamin $B_6$; determined plasma pyridoxal 5'-phosphate (PLP); and assessed vitamin $B_6$ status of Korean adults. MATERIALS/METHODS: Three consecutive 24-h diet recalls and fasting blood samples were collected from healthy 20- to 64-year-old adults (n = 254) living in the Seoul metropolitan area, cities of Kwangju and Gumi, Korea. Vitamin $B_6$ intake and plasma PLP were analyzed by gender and by vitamin $B_6$ supplementation. Pearson's correlation coefficient was used to determine associations of vitamin $B_6$ intake and plasma PLP. RESULTS: The mean dietary and total (dietary plus supplemental) vitamin $B_6$ intake was $1.94{\pm}0.64$ and $2.41{\pm}1.45mg/day$, respectively. Median (50th percentile) dietary intake of men and women was 2.062 and 1.706 mg/day. Foods from plant sources provided 70.61% of dietary vitamin $B_6$ intake. Only 6.3% of subjects consumed total vitamin $B_6$ less than Estimated Average Requirements. Plasma PLP concentration of all subjects was $40.03{\pm}23.71nmol/L$. The concentration of users of vitamin $B_6$ supplements was significantly higher than that of nonusers (P < 0.001). Approximately 16% of Korean adults had PLP levels < 20 nmol/L, indicating a biochemical deficiency of vitamin $B_6$, while 19.7% had marginal vitamin $B_6$ status. Plasma PLP concentration showed positive correlation with total vitamin $B_6$ intake (r = 0.40984, P < 0.0001). CONCLUSIONS: In this study, vitamin $B_6$ intake of Korean adults was generally adequate. However, one-third of subjects had vitamin $B_6$ deficiency or marginal status. Therefore, in some adults in Korea, consumption of vitamin $B_6$-rich food sources should be encouraged.

To assess the nutritional and health status of the elderly, anthropometric measurements and blood test for analyzing biochemical indices were carried out from August to September in 1996. Data on the incidence of a specific disease and clinical symptoms were also collected by interviews with a questionnaire. Among the total of 169 free-living elderly interviewed(91 men, 78 women), 86 elderly(57 men, 29 women) participated in the anthropometric measurements, and 73 elderly(52 men, 21 women) in blood tests. Average heights and weights were much lower than the standards established in the Korean Recommended Dietary Allowances. While average triceps skinfold thickness of men and women were above the 50 percentile of the reference data, mid-arm muscle circumferences were lower than the 50 percentile. Prevalences of anemia, assessed by hemoglobin using WHO definition, were 38.5% for men and 33.3% for women. Blood levels of total protein and albumin were above the normal limit for all participants. Mean blood cholesterol levels of men and women were 163.9mg/dl and 185.8mg/dl, and triglyceride levels were 138.2mg/dl and 161.9mg/dl, respectively. Women older than 75 years generally had high levels of BMI, total cholesterol and triglyceride. Health status assessed by clinical symptoms generally showed no significant difference by age, and their smoking, and drinking habits. Males and the elderly who exercised regularly had better health status. It was suggested that exercise was a good way to improve health status. (Korean J Community Nutrition 2(4) : 568-577, 1997)
