  • This study was carried out to know the food habits of 200 persons, 89 males and 111 females, aged 60 years and over from June 13 to July 2, 1977 in Seoul. The results are summarized as follows: 1. Changes of the food preferences The preferences about foods after 60 years of age showed in lower scores of dislikes than those before and, however, were not significantly changed. Beef was the item which 75% of the subjects liked and was the highest in desire to eat, Likes for hot, salty, and sour taste except sweet were diminished but they generally liked hot or sweet food rather than sour or salty one and also warm dish rather than cold one. A majority of them wanted to have their meals cook more soft and tender. 2. Intakes of foods The average consumptions of the basic food groups per capita per day were 475.5g of males .and 431.8g of females for cereals and grains, 119.6g and 103.6g for meats add legumes, 221.7g and 216. lg for fruits and vegetables, 52.6g and 39.4g for milk and small fishes, and 5.0g and 4.7g for fats and oils. 3. Intakes of calorie and nutrients The percentage contributions of three nutrients, carbohydrate, protein, and fats to the total amounts of calories were 75.9, 12.4, and 11.7% of mates and 75.6, 12.4, and 12.0% of females. Women had a slightly higher percentage of caloric intake to RDA than men who didn't satisfy RDA. The subjects revealed an insufficient protein intake as well as calcium. Therefore, many older people have to be convinced of the importance of milk for both nutrients. The mean ratios for iron, niacin, and thiamin intake were higher than RDA and on the contrary. those for riboflavin, vitamin A, and ascorbic acid intake were below RDA. It seems necessary, for the aged to maintain good state of health, to promote their appetite, and to take regular mealtime because difficulty of teeth, illness, irregular mealtime, and loss of appetite had influence on less intakes of calorie and nutrients.

  • This paper aims at an investigation of the features of bacterial communities in surface sediments of the South China Sea (SCS). In particular, biogeographical distribution patterns and the phylogenetic diversity of bacteria found in sediments collected from a coral reef platform, a continental slope, and a deep-sea basin were determined. Bacterial diversity was measured by an observation of 16S rRNA genes, and 18 phylogenetic groups were identified in the bacterial clone library. Planctomycetes, Deltaproteobacteria, candidate division OP11, and Alphaproteobacteria made up the majority of the bacteria in the samples, with their mean bacterial clones being 16%, 15%, 12%, and 9%, respectively. By comparison, the bacterial communities found in the SCS surface sediments were significantly different from other previously observed deep-sea bacterial communities. This research also emphasizes the fact that geographical factors have an impact on the biogeographical distribution patterns of bacterial communities. For instance, canonical correspondence analyses illustrated that the percentage of sand weight and water depth are important factors affecting the bacterial community composition. Therefore, this study highlights the importance of adequately determining the relationship between geographical factors and the distribution of bacteria in the world's seas and oceans.

  • Purpose: This study was done to apply Andersen's behavioral model to identify factors that determine oral health-related quality of life in elderly persons. Methods: Participants were 257 people ages 65 years or older. Data were analyzed using frequency, percentage, mean and hierarchical multiple regression. Results: The variables in the behavioral model, predisposing factors, enabling factors and need factors, explained 31% (F=12.7, p<.001) of variance in oral health-related quality of life. The predisposing factors, enabling factors, need factors and health behavior collectively explained 35% (F=9.22, p<.001) of variance in oral health-related quality of life. Factors influencing oral health-related quality of life in older adults were ADL and IADL, self-reported oral health status, xerostomia and dental care in last 12 months. Conclusions: The analysis results showed that the need factor had the highest level of relative importance of the three factors. The model used for this study can be used to predict oral health-related quality of life.

  • The study investigates the utilization of open access repositories for visibility of academic publications by lecturers in South-East, Nigeria. The specific objectives were to investigate the types of academic publications available, platforms used in self-archiving, level of satisfaction derived by lecturers with the contribution of open access repositories, challenges and strategies. It adopted descriptive survey design. Proportionate stratified sampling technique was used to draw a sample size of 418 from the total population of 4,187 lecturers. Questionnaire and observation check list were used for data collection. Frequency count, percentage, and mean score were used to analyze the data. The study revealed that there are enough academic publications available such as books, journals, projects, and thesis with the exception of handouts. It also revealed that Google Scholar, Research Gate and Open Access Journal were the main platforms lecturers use in self-archiving; while other platforms like Institutional Repositories, among others were minimally employed. Lecturers are less satisfied with the contribution of open access repositories. All the suggested challenges such as inadequate power supply, poor network, lack of awareness and inadequate research grants were all accepted. Similarly, all the suggested strategies for improving them were accepted. Recommendations were made based on the findings such as more awareness creation on importance of open access repositories; re-training of lecturers and provision of adequate ICT infrastructures that will improve the utilization of open access repositories by lecturers which could enhance the global visibility of academic publications from the Nigerian Universities.

  • This study presents the estimation of crack depth by analyzing temperatures extracted from thermal images and environmental parameters such as air temperature, air humidity, illumination. The statistics of all acquired features and the correlation coefficient among thermal images and environmental parameters are presented. The concrete crack depths were predicted by four different machine learning models: Multi-Layer Perceptron (MLP), Random Forest (RF), Gradient Boosting (GB), and AdaBoost (AB). The machine learning algorithms are validated by the coefficient of determination, accuracy, and Mean Absolute Percentage Error (MAPE). The AB model had a great performance among the four models due to the non-linearity of features and weak learner aggregation with weights on misclassified data. The maximum depth 11 of the base estimator in the AB model is efficient with high performance with 97.6% of accuracy and 0.07% of MAPE. Feature importances, permutation importance, and partial dependence are analyzed in the AB model. The results show that the marginal effect of air humidity, crack depth, and crack temperature in order is higher than that of the others.

  • The purpose of this study was to evaluate nurses' perception of clinical nutrition services. A cross-sectional survey design was performed. The research was accomplished by using questionnaires developed for this study and administered from September 12 to December 31, 2013 to 343 nurses at 43 tertiary hospitals and 20 general hospitals. The percentage of nurses who recognized clinical nutrition certificate as issued from nation was 27.8%. The mean scores of perceived usefulness on clinical nutrition services was 4.23/5.00, whereas that of perceived implementation was 3.76/5.00. The mean scores of necessity of disease-specialized clinical dietitian at capital hospitals were significantly higher for obesity (P<0.01), cancer (P<0.05), and infant & childhood disease (P<0.01) than at local hospitals. The rates of nurses' experience in group education on cancer at capital hospitals (21.7%) was significantly higher than that at local hospitals (10.3%) (P<0.05). The mean scores of perceived importance of clinical nutrition services were 4.46/5.00 for 'group nutrition education', 4.46/5.00 for 'individual consultation', and 4.40/5.00 for 'nutrition management for enteral nutrition (EN) patients'. The most common reason why clinical nutrition services are important was 'improving malnutritional status'. To activate clinical nutrition services especially at local hospitals, clinical dietitians should give systematic assistance to patients and also institutional supports are needed.

  • This study has been focused on understandings for the problems of dietitian who perform nutrition service in the field of industry foodservice and then focused on using of its findings as basic material for smooth nutrition service performance through analyzing job satisfaction, job characteristic and its importance of dietitians' task in industry foodservice. A questionnaire survey of 120 nutritionists who have engaged themselves in industry foodservice―60 are under direct management and 60, held in trust―has been performed, and 95 responses (79%) have been collected and categorized, except some unfinished responses. The examined data have been classified statistically by using of SPSS, and then analyzed into frequency, percentage, mean value, standard deviation, and correlation among factors, according to questionnaires. The findings of the research can be summarized as following: The details of the surveyed dietitians were: 20-25 years old on an average; working less than two years; college graduates; mere employees; receiving monthly pay of 70~100 won on an average; working more than 52 hours weekly; and providing with four meals a day in a single menu. For job satisfaction and job characteristic, the service itself and the understanding of the service appear as main features. For the relative importance of the service, the findings show that the menu making, sanitation and cost control occupy an important position, while nutrition counseling, nutrition education and dietary control by ailments make up very low portion. For the cause of not enacting the nutrition service, the lack of counseling ability and the overburden of food service are at the top. The findings of this research, therefore, present the needs of the service capacity education and the reduction of excessive foodservice hours of dietitians in order to secure the efficient nutrition service in industry foodservice. To achieve this goal, first of all, there should be an intensive education course in school by using of practice hours. for enhancing practical service adaptability, and then the computerization of foodservice should be executed perfectly to reduce the excessive foodservice hours.
