The purpose of the present study was aimed to identify dish items applicable in developing dish?based food frequency questionnaire (DFFQ) for a hypertension study of Koreans. The 24-hour recall data of 4,401 subjects aged $20{\sim}65$ years from the 2001 Korean National Health and Nutrition Examination Survey were used for the analysis. Logistic regression model was used to identify the nutrient related with hypertension. Energy, fiber, sodium, calcium, carotene, vitamin B1 and vitamin C were associated with hypertension. Selection the top 30 dish items for these seven nutrients was performed based on their degree of contribution in supplying nutrients in terms of the cumulative percent contribution (cPC), as well as on their degree of explanation for between?person variation, in terms of the cumulative regression coefficient (cMRC). Rice supplied 43% of total energy consumption. Korean cabbage and radish kimchi were two major sources of sodium and it also covered the 27% of between person variation of sodium intake. Soybean paste soup and single item of orange?colored fruits supplied 43% of total vitamin C intake for Koreans and it covered the almost 79% of between person variation among the Korean population. Korean cabbage kimchi was the major source of fiber, calcium, sodium, carotene, and vitamin C for Koreans. In summary, the top 30 selected dish items supplying the 78% to 89% of the 7 nutrients. Those items also covered the 79% to 94% of between person variation of the 7 nutrients consumption. Therefore, the selected 30 dish items in each categories of nutrient could be applicable in developing dish based food frequency questionnaire for hypertension study.

BACKGROUND/OBJECTIVES: In Korea, studies of diet in elementary school children are hindered by the need for a comprehensive dietary assessment tool. Thus, the aim of this study was to develop a semi-quantitative food frequency questionnaire (FFQ) for Korean elementary school children. SUBJECTS/METHODS: The 24-h recall data for 1,624 subjects aged 6-11 yrs from the seventh Korea National Health and Nutrition Examination Survey were used to extract the items included in the questionnaire. The FFQ items were developed by selecting major dishes based on the results of nutritional contribution and between-person variability for energy and 14 nutrients (carbohydrate, protein, fat, crude fiber, calcium, phosphorous, iron, sodium, potassium, vitamin A, thiamin, riboflavin, niacin, and vitamin C). We selected the major dishes with over 90% of the total contribution to each nutrient and with over 90% of the accumulated R² for each nutrient. Among the 452 dishes, we selected 248 dishes contributing more than 1% of the total consumption. RESULTS: Finally, the FFQ included 107 items combined from 248 dishes based on nutrient profile and recipe. The FFQ items accounted for an average of 88.6% of the energy, 14 nutrient intakes, and 91.4% of the between-person variability. Quantities of dietary intake were assessed by 9 categories of frequency and 3 categories of portion size. Percentages of coverage for energy, protein, fat, carbohydrate, and calcium were 90.2%, 87.8%, 89.9%, 90.8%, and 88.7%, respectively. CONCLUSIONS: We developed a dish-based, semi-quantitative FFQ comprising 107 items for Korean elementary school children aged 6 to 11. Further studies are needed to evaluate the reproducibility and validity of this FFQ for elementary school children.

Objectives: The purpose of the study is to investigate the knowledge, attitudes, and needs of smoking cessation education in the dental hygienists. Methods: A self-reported questionnaire was completed by 262 dental hygienists in Seoul and Gyeonggido from September 25 to December 31, 2015. Except incomplete answers, 250 data were analyzed using Stata 13.0 program. The questionnaire was adapted and modified from Kim and Yoon and was measured by Likert 3 or 5 point scale. The questionnaire consisted of general characteristics of the subjects(6 items), smoking cessation education characteristics of the subjects(4 items), knowledge of smoking cessation education (11 items), attitudes of smoking cessation education(9 items), and needs of smoking cessation education(11 items). Results: Those who said yes in smoking cessation education had higher scores in knowledge (p=0.001), attitudes (p<0.001) and needs of education (p=0.010). Those receiving smoking cessation education higher score in knowledge of smoking cessation education (p=0.017). The dental hygienists working in clinics that practice smoking cessation therapy program tended to have higher level of attitudes toward smoking cessation(p=0.030). The average scores for 11 items to assess knowledge of smoking cessation education and another 11 items to assess the need for smoking cessation education were $2.18{\pm}0.40$ out of 3 and $4.62{\pm}0.49$ out of 5, respectively. Conclusions: The smoking cessation education is very important to improve the knowledge, attitudes, and need of smoking cessation in the dental hygienists.

This study sought to compare intake levels of major dish items and food groups between normal and obese Korean children in order to understand obesity-related eating behaviors. The study was also conducted to apply the information on the differences in major dish items and food groups found in this study to development of a brief food frequency questionnaire (FFQ) for children's obesity-related eating behaviors. Finally, the developed FFQ was evaluated for reliability. A total of 290, 24-hour dietary recall data from 9-11 year-old normal or obese participants in the 2001 Korean National Health and Nutrition Examination Survey (KNHANES) were reviewed to identity dish items and food groups showing outstanding differences between the normal and obese groups. Based on the level of intake amount between the two groups, a total of 7 items, including ddeokbokggi, spaghetti, ham roast, pork cutlet, dairy products & ices, kimchi, and fruits, were selected to be included in the FFQ. The former 5 items were seen to be consumed more in the obese group, while the latter 2 items were so in the normal group. The questionnaire was formatted into a frequency response section of a seven-category option and reference period of the last 7 days. Test-retest reliability of the developed FFQ was examined by administering it to 153, 9-11 year-old children at a public elementary school in Seoul twice at a month interval. The level of reliability was found to be reasonably high. In conclusion, this study suggests that high consumption of several high-calorie dish items and low consumption of kimchi and fruits may be important eating behaviors in relation to obesity risk among 9-11 year-old children who need nutrition educators' attention. The current study also implies that a simple FFQ can be utilized to reliably assess 9-11 year-old children's diets.

The purpose of this study was to investigate the relationship between perceptual orientation and four aspects of clothing behavior. Perceptual orientation was measured with Choi's Perceptual Orientation Scale, and clothing satisfaction was assessed with Lim and Lee questionnaire. Clothing importance was measured with some items of Kirby's Clothing Attitudes and additional items prepared for this study, Clothing comfort was measured Ivith some items of Creekmore Scales of Eight Clothing Variables and additional items prepared for this study. Clothing conformity was measured by some items of Selker's The Clothing Conformity Inventory and Carpenter's Clothing Opinion Scale and the Kim questionnaire, along with additional items for this study. Altogether 43 items were used. The questionnaire was completed by 480 second year junior and senior high school boys in Seoul. Statistical analysis was performed using the correlation coefficient, t-tests, multiple regression analysis, and analysis of variance. The results were : 1) Perceptual orientation was positively related to clothing satisfaction. 2) Perceptual orientation was negatively related to clothing conformity. 3) Scores of senior high school boys on self-perception and total perception were significantly higher than these of junior high school boys. 4) Clothing satisfaction, clothing conformity and clothing importance were different according to the grade level. That is, junior high school boys had a higher clothing satisfaction ana senior high school boys had a higher clothing conformity and clothing importance score.

The purpose of this study was to promote the popularization of hospice services by providing the information about the influences of hospice training on participants. We compared differences of attitudes toward death between those of pre-training and post-training by use of questionnaire. This study involved 137 volunteers participating in the hospice training held by one hospice center located in K-city. The questionnaire was composed of 46 items, 21 items of general information and 25 items of information about attitudes toward death. We applied Park's translated version(1992), originally distributed by Thorson and Powell(1988), in the assessment of participants' changed attitudes toward death. Participants were asked to fill out the questionnaire before and after the hospice training. The data were analged by frequency. ANOVA t-test, paired t-test. The results were as follows, 1.Pre-training items holding a high rank were 'The subject about the future life after death is distressing'(F=5.20), 'No worry about any occurrences around the body after a funeral'(F=4.75), 'Having little interest in being laid in a coffin after death'(F=4.56); items holding a low rank were 'Having little interest in any occurrences around the body after death'(F=2.22), 'Willing to deal with the aftermath of the death in detail'(F=1.94), 'No fear to have an idea to be cancerous'(F=1.72). 2.Post-training items holding a high rank were 'No fear to be dead as a result of sufferings from long-lasting illness'(F=3.18), 'No fear to have an idea to be cancerous'(F=3.16)', Having little interest in the future life after death'(F=3.09); items holding a low rank were 'Unpleasant to be not able to move after death(F=1.74), 'Distressing not to know about the future life after death'(F=1.61), 'The subject about the future life after death is distressing'(F=1.60). 3.There were significant difference in participants' attitudes toward death. Compared with pretraining(F=3.97), more positive were developed in post training(F=2.30). The results of this study indicate that hospice training renders positive regards toward death to the participants. Therefore every human being, who is able to speculate about the meaning of death, has to be exposed to the hospice training. In conclusion, hospice training should be popularized in the near future.

Three hundred and fourteen low back pain patients completed the Korean version of the Oswestry Disability Questionnaire (KODQ) and the Rasch analysis was then applied to identify the inappropriate items and to determine ODQ item difficulties according to a subject's characteristics. For women and youths, the 'sex life' item showed misfit statistics, whereas for older subjects it was the 'pain intensity' and 'standing' items. Also, in the acute low back group the 'pain intensity', 'standing' and 'sex life' items showed misfit statistics. For all subjects, the most difficult item was 'pain intensity', whereas the easiest item was 'walking'. But for the older and acute groups 'lifting' was the most difficult item and for those who have a visual analogue scale score of 3 or less 'sitting' was the most difficult item. These results show that differential item functioning is present in several items according to sex, age, acute and chronic pain, and VAS score. This study may be useful for adjusting the KODQ item difficulties for low back pain patients with different characteristics.
