The single-scattering optical properties of ice crystals in cirrus clouds by the aircraft measurement data were investigated, and the radiative equilibrium temperatures and radiative fluxes were calculated and analyzed by radiative convective model with the variations of ice crystal habits and sizes in cirrus clouds. The homogeneous cloud is assumed to be in the layer 200~260 hPa with an ice crystal content of $10gm^{-2}$ for the flux calculation. The profiles of temperature, humidity, and ozone typical of mid-latitude summer are used. The surface albedo is assumed to be 0.2 for all spectral bands and the cosine of solar zenith angles is 0.5. The result of radiative equilibrium temperature at surface was less than surface temperature of the standard atmosphere data in case of smaller effective ice crystal size and larger optical thickness. The column, aggregation and plate in 6 ice crystal habits were the most effective in positive greenhouse effect and bullet-4 was the worst in it. At the surface, the maximum difference of equilibrium temperature by 6 kinds of ice crystal habits were about 3~15 K with 30 sample aircraft measurement data.

The study examines the role of facilitating conditions and user habits in the use of technology in Online Learning Platform (OLP) in Indonesia. The adoption of online learning, persistence, and learning results in online platforms is essential for ensuring that education technology is implemented and gets as much value as possible. People who use technology and systems will embrace new technologies even more. This quantitative study is based on a survey of 254 respondents, who were active users of the technology, and considers the facilitating conditions and user habits variables. Two research hypotheses were tested using the Partial Least Square-Structural Equation Modeling method. Cronbach's Alpha, path coefficient, AVE, R-square, T-test were applied. The results showed that the factors significantly influence the Online Learning Platform technology behavioral intention. This impact is primarily associated with the availability of the resources required to use OLP technology. The availability of these resources includes supporting infrastructures such as widespread Internet access, easy access to mobile devices, and file sizes that affect access speed. The findings of this study suggest that it is necessary to introduce and increase the availability of resources for using OLP technology, and familiarize people with the technology features.

To investigate the effect of food habits on the bone state of the senior citizens, two groups were tested: one(111 senior citizens) was healthy ordinary senior citizens over 65 years old and the other(51 senior citizens) was patients distinguished as having osteoporosis. The present dietary intake was estimated by a 24-hr recall method, and individual history. For the data analysis, percentages and frequencies were calculated and χ²-test was undertaken to test the relation among values. The following results were obtained: patient group with osteoporosis was less in height and weight than the group of ordinary senior citizens(160.33cm, 59.99kg). It was much less than the average Korean senior citizens(158cm, 54.9kg). Food appetite in the group of patient was worse than that of ordinary senior citizens group. According to their dietary history(58.8%), the food intake pattern was most of vegetables(62.0%). Eventhough they haven't been intaken milk after recognizing of their osteoporosis(74.5%). Most of them didn't improve their food habits to help Ca metabolism. Also they have depress of their life(50%). All subjects certainly took insufficient energy, Ca, protein from their diets. Moreover the major source of Ca were vegetables, seaweeds and legumes.

This study was conducted to investigate food habits and eating behavior of preschool children. Food habit, eating behavior and health status were investigated by using a questionnaire answered by the mothers of 312 children aged 6 to 7 years old who lived in Uiwang. The average height, weight, Kaup index were 115.08cm, 21.41 kg, 16.13, respectively, for boys 111.37 cm, 19.93 kg, 15.72 for girls. Results showed that 72.16% of subjects skipped the breakfast meal. One of the main reason fur skipping breakfast was 'no appetite'(53.14%). It was found that 49.67% of the subjects belonged to 'good' in health status. The eating behavior of 'watching TV or playing a toy during meal' and 'can eat the rice by oneself were significantly higher score in girls than in boys(p<0.05). Food attention of the parents for the health of children was the highest in 'keep regular meals a day'(92.65%). Health status showed significantly negative correlations with kaup index and eating behavio(p<0.001). Kaup index(p<0.05) and health attention(p<0.001) were positively related with eating behavior. Based on this study, nutritional education program for preschool children would be required for the dietetics teacher to guide the children and more attention should be paid to the nutritional education of food habits in this age group and their mothers.

This study was carried out in order to investigate Korean food acculturation by married immigrant women and how it affects their children's eating habits. Using an in-depth interview method, 26 domestically residing married immigrant Chinese, Vietnamese, and Indonesian women in Korea were surveyed to investigate adaption to Korean food at the time of their immigration, their current dietary life, their preferred Korean food, major factors in managing their children's eating habits, etc. The results reveal that depending on the married immigrant women's country of birth, which plays an important role in a family's dietary life and health, acculturation phenomena occurred in which the specific eating habits of each country were grafted into Korean food. Furthermore, due to their school-age children's display of acceptance of both their homeland's and Korea's food culture, we believe that this can become a pivot point for non-governmental diplomacy where Korean food can be understood along with the mothers' countries.

The purpose of this study is to investigation the eating habits and health-related behaviors of adolescent students. 700 students are randomly selected in 6 high schools in Chunchon area. The most students take three meals a day. but most of girl students take less two meals a day or often go without a meal. There are the tendency that boy-students are more satisfied with their meal habits, but they have the health problems caused by irregular meals. There are more boy-students have the regularity of meal habits than girl students. and the former have the more tendency of going without a meal than the later which shows that girl-students have to give more attention to their health management. Their sleeping hours are not enough to recover the tiredness. The higher grads they are in the less time they have to take a rest. The tenth grads students are shown to feel the most serious stress. but have few opportunities to take a medical examination, which means that we have insufficiency of health education as a precautionary measures. Accordingly, it is important that teachers have to provide students with education of good meal habit which is fit to their real life. In modern times, as there are the tendency that more women participate in the social activity. we will reinforce the education that the boy-students may take active part in the health management without distinction of the roles between boy and girls-students.

The purpose of this study was to investigate eating habits and dormitory foodservices' satisfaction in university students using dormitory foodservice in the Jeollabuk-do Iksan area. Self-administered questionnaires were completed by 195 students (86 male, 109 female). Many students (58.5%) ate less than two meals per day and spent around 30 min eating meals. The results show that snack and midnight meals were the main reasons (37.9%) for unhealthy eating habits. Main source of nutritional knowledge and information were TV and the Internet (58.5%), followed by friends and people (25.1%), nutrition books (10.3%), elective courses (4.6%), and newspapers and magazines (1.5%). Men had significantly higher satisfaction scores for nutrition, taste, diversity of menu, as well as hygiene of dormitory food court compared to women (p<0.05). Salty taste was the most important factor in evaluation of taste satisfaction, whereas sour taste was opposite. The reason for taste dissatisfaction in the dormitory food court was not salty enough, and it may be related with their eating habits. The results show that students need education for adequate knowledge and information about the relationship between health and nutrition.
