The middle school subjects were 65.8% girls and 34.2% boys. Seniors were most abundant at 56.3%. The most abundant location was Gyeonggi-do (54.7%), and 69.3% of subjects were living with 4?5 family members. Approximately 56% of the mothers had graduated from high school, and 58.1% were unemployed. The mother most often prepared the food (78.4%), fish was eaten mostly in the home, and taste was the most important factor (62.6%). The preferred home food menu was fish because it is healthy, and the main cause for disliking the school meal service was poor quality dishes compared to a home cooked meal. The acceptance and type of fish were proportional. Rice was the most favored dish to eat with fish and scored 3.97, the highest rank. Approximately 50% answered that fish was nutritious, and a significant difference was observed regarding the mother's educational background (p<0.05). Students who never had a lecture about fish answered that fish was not nutritious, which showed a significant difference with education (p<0.05). Approximately 44% of students ate fish 2?3 times per week, and male students showed a significantly higher intake of fish than female students (p<0.05). The poorly educated disliked fish the most, and the higher frequency intake of fish resulted in a significantly higher percentile (p<0.001).

Background: Determining patterns of habitat use is key to understanding of animal ecology. Approximately 1% of bird species use brood parasitism for their breeding strategy, in which they exploit other species' (hosts) parental care by laying eggs in their nests. Brood parasitism may complicate the habitat requirement of brood parasites because they need habitats that support both their host and their own conditions for breeding. Brood parasitism, through changes in reproductive roles of sex or individual, may further diversify habitat use patterns among individuals. However, patterns of habitat use in avian brood parasites have rarely been characterized. In this study, we categorized the habitat preference of a population of brood parasitic lesser cuckoos (Cuculus poliocephalus) breeding on Jeju Island, Korea. By using compositional analyses together with radio-tracking and land cover data, we determined patterns of habitat use and their sexual and diurnal differences. Results: We found that the lesser cuckoo had a relatively large home range and its overall habitat composition (the second-order selection) was similar to those of the study area; open areas such as the field and grassland habitats accounted for 80% of the home range. Nonetheless, their habitat, comprised of 2.54 different habitats per hectare, could be characterized as a mosaic. We also found sexual differences in habitat composition and selection in the core-use area of home ranges (third-order selection). In particular, the forest habitat was preferentially utilized by females, while underutilized by males. However, there was no diurnal change in the pattern of habitat use. Both sexes preferred field habitats at the second-order selection. At the third-order selection, males preferred field habitats followed by grasslands and females preferred grasslands followed by forest habitats. Conclusions: We suggest that the field and grassland habitats represent the two most important areas for the lesser cuckoo on Jeju Island. Nevertheless, this study shows that habitat preference may differ between sexes, likely due to differences in sex roles, sex-based energy demands, and potential sexual conflict.

The purpose of the study is to see how much of changes has occurred in the newly revised Home Economics Textbooks required by the 6th Curriculum as compared to those by the former 5th Curriculum, and to seek future policy directions which can be improved even better, if any, for further revision. To implement this proposal, the study employs 8 different textbooks published in 1996 geared for the 6th Curriculum for data base. The components of the contents divide into two major parts. The first part falls into a category of holistic analysis of the textbooks, which gives a general perspective of the changes in the textbook revised. It includes those areas of changes in the total number of pages, cover page, illustration, total of contents, appendices, unit cover, introductory remarks, summary and evaluation, etc. It also covers the information on authors of textbook. The latter part consists of several specific areas of major changes occurred in the textbooks for the 6th Curriculum. It covers such areas of changes in the composition of category and its weight, laboratory experiences, and illustrations and tables. To conclude the study, among many findings, two major points are of great importance to mention here. First, the new textbooks have adopted more of varieties in physical appearances and contents per se as to the older ones. And yet, there still found a weakness in numbers of authors participated to a full reflection of contents variety. In addition, the background of authors reflected on an unrealistic idealism which lacks the on-site information provided by the school teachers. Second, the strict regulations created by the Ministry of Education for developing textbook found restricting the authors creativity and thus contents variety of textbooks.

The purpose of this study was to survey the actual condition of the Middle School Students on a Drug. In this study, 500 middle school students in Seoul response to a questionnaire which is composed to analyse two categories, i.e. general facts, the actual condition of drug use (the frequency of drug use, the degree of perception on drugs, the people using a drug surrounding the degree of purchase on drugs). And the students are classified by satisfactory degree on their home backgrounds, satisfactory degree on their school life, and school record. The data is analysed by means of frequency, percentage, chi-square test and Pearson's correlation using the $SPSS-PC^+$ package program. The results of this study were as follow : The frequency of drug use except a alcohol and the degree of perception on a drug among female students are higher than among male. The female students are more permissive on the drug use and they are also tend to think more easily the purchase of a drug. The frequency of drug use and the degree of perception on drugs are higher in the group of the lower satisfactory degree on their home background. Especially, there are many people using drugs surrounding the students in the lower group. The frequency of drug use and the degree of perception on drugs are higher in the group that has the lower satisfactory degree on school life. The students in the group having low school record have more dangerous thought about the use of drugs than the students of high record. The degree of perception on a drug is higher in a higher group, and the students in a higher group also think more easily the purchase of drugs. The percentage of students using drugs are not high, but the high percentage of students are interested in the drugs and they have permissive attitudes on drugs. Thus, the preventive education for drug abuse must be done rapidly.

Food choice is influenced by many factors including physical, social, psychological and food technological developments. This research is based on the survey on Puchon housewives dietary culture according to season and special occasions and the current consumption pattern of traditional fermented foods. The objective is to find out the current consumption and to use this data as the principal element needed to explore changes in consumption patterns and to uphold and develop the consumption of traditional fermented food. Questionnaires were collected 282 housewives in Puchon city. Data were analysed with SAS software package for t-test, F-test and Duncan’s multiple range test. Results of relationship between dietary culture of Puchon housewives and consumption patterns of traditional fermented food items; 1. If we look at seasonal foods, Puchon housewives responded that they normally prepare traditional foods for such special occasions as Chusok(89%), New Year(84%) and January full moon Day(77%). For family celebrations, they cook on their in-laws birthdays(91%), their husbands birthday(84%), childrens birthdays(73%) and their own birthday(32%). They also responded that they eat out on their own birthday(41%), on Christmas Day(19%), on childrens birthdays(17%) and on their husbands birthday(11%). 2. If we look at the age of housewives and their dietary culture, more young housewives tend to eat out on their own, their husbands and their childrens birthdays. As for their educational background, less educated housewives tend to prepare flood at home on New Years Day, while more educated housewives would eat out on their own birthdays. As for the type of family, mere housewives in nucleus families eat out on Christmas Days compared to those in extended families. Also, those in extended families tend to make food at home rather than eating out on their own birthdays. In case of the husbands birthday, there was some difference according to family income (p<0.03).

Background: This study was undertaken to compare the outcome of supervised and home exercises with respect to range of motion (ROM), pain, and Single Assessment Numeric Evaluation (SANE). We further correlated the ROM recovery and pain reduction as well. Methods: The study included 49 patients who underwent arthroscopic rotator cuff repair. Rehabilitation was initiated after 4 weeks of immobilization. A total of 29 patients performed supervised exercise 3 times a week. Standardized education and brochures for review were provided to the remaining 20 patients who insisted on home rehabilitation. Statistical analysis was performed for comparing pain Numerical Rating Scale (NRS), SANE, and ROM. In addition, we also evaluated the correlation between pain and ROM. Results: Comparison of the two groups revealed no significant differences in forward flexion, internal rotation, abduction, and pain NRS. However, SANE at the 9th week (63.8 vs. 55.0, p=0.038) and improvement of external rotation from the 5th to the 9th week (17.6 vs. 9.3, p=0.018) were significantly higher in the supervised exercise group as compared to the home exercise group. Correlation of pain NRS with forward flexion, external rotation, internal rotation and abduction were statistically not significant (correlation coefficient=0.032 [p=0.828], -0.255 [p=0.077], 0.068 [p=0.642], and -0.188 [p=0.196], respectively). Conclusions: The supervised rehabilitation after arthroscopic rotator cuff repair showed better improvement in external rotation and higher SANE score after 4 weeks of rehabilitation exercise. However, no statistically significant correlation was observed between the recovery of ROM and short-term pain relief.

Background: About 60% of patients with epilepsy showed a variety of complications after returning home. The purpose of this study is to get further information and to help in the anesthetic management of the disable patients with epilepsy. Methods: After searching the outpatient anesthesia list of Seoul National University Dental Hospital clinic of the disabled from September 2010 to March 2012, we found total 83 patient cases who were taking antiepileptic drugs. A nurse of anethesiology department called to the patient's home after general anesthesia and got surveys with questionnaires form filled with complications at home. We enrolled total of 51 patients who agreed to participate this survey. And we also reviewed pre-anesthesia evaluation sheet, anesthesia record, and recovery and discharge record. Results: 11 of 51 (21.6%) patients had seizure convulsion at home within 1 weeks. 33.4% of patients who had at least once seizure attack per week had a seizure attack within 3 days. And 50% of once a month frequency patients had a seizure attack within 1 week. 33% of 1 - 3 seizure attacks per year patient group had a convulsion within 1 week. But there was no seizure attack within 1 week in whom had no seizure attack history during more than 1 year. Conclusions: After dental treatment, patient taking anticonvulsant have so many complications-especially seizure, more than we respected. We need more research about handle these problems.

Background: Physical activity (PA) is critical for maintaining the health and well-being of older people in community and also institutional settings. The purpose of this study was to examine the current status of PA and related individual and organizational factors among older nursing home residents with and without dementia. Methods: This is a secondary data analysis study of a nationwide survey of 92 long-term care facilities in Korea, and the study sample includes older residents with dementia (n= 753) and without dementia (n= 480). The level of PA was measured by PA time and whether or not residents had an outdoor activity over the past 3 days. Multi-variate, multi-level analyses were conducted. Results: More than half of the sample in both groups had no or less than 1 hour of PA. About one out of four older people in our sample had no outdoor activity over the past 3 days regardless of whether or not they had dementia. Among the people without dementia, several individual-level factors were associated with PA, including dependency for activities of daily living, social activity participation, and caregivers' belief in the functional improvement of residents. Unlike the non-dementia group, individual- and organizationallevel factors including staffing level and having the relevant equipment for PA were associated with PA among those with dementia. Conclusion: Study findings provide evidence on the lack of PA among older nursing home residents, and the importance of institutional capacity with regard to human resources and physical equipment for promoting PA among people with dementia, in particular. Policies and supports are needed to promote the implementation of healthy aging programs including PA for older nursing home residents. Such programs should be person-centered with consideration to the physical and cognitive status of individual residents.

Background: In this study, the bleaching effect and surface damage of two types of over-the-counter home tooth bleaching agents were explored using an in vitro study of bleaching agents applied to bovine teeth specimens for 14 days. Methods: Domestic over-the-counter home tooth bleaching agents of gel and patch form that shared common active ingredients and manufacturers were selected and tested. The experiment specimens were made using composite resin with bovine tooth samples and then measured the initial microhardness. Specimens were then divided into a Gel group and a Patch group and underwent bleaching treatment once a day for two weeks for 30 to 60 minutes (recommended) or 7 hours. All specimens were coffee-stained prior to bleaching. The bleaching effect was measured using a spectrophotometer and surface damage was measured using a microhardness meter. Results: The difference in color following the bleaching procedure was positive in both the Gel and Patch group, although there were no statistically significant differences in bleaching effect between groups. There was no significant difference in bleaching effect based on duration. The microhardness test revealed that both the Gel group and the Patch group had surface damage after bleaching. The greatest surface damage was found in the Patch group that had undergone a 7-hour bleaching treatment, although the differences were not statistically significant. Conclusion: The bleaching effect of the home tooth bleaching agent was visible to the naked eye. However, longer applications than recommended did not result in greater bleaching, unlike consumers' expectations, and instead increased the chance of enamel damage. As such, there is a need for consumers to be alert and adhere to recommendations provided by each company.
