The purpose of this study was to examine the oral health awareness and oral health care of health-related and health-unrelated majors in an attempt to stress the importance of oral health education and boost the efficiency of oral health care. The subjects in this study were 363 college students. Out of the selected students, 174 were health-related majors, and 189 weren't. After a survey was conducted, the collected data were analyzed for the purpose of comparison, and the following findings were given: 1. Concerning daily mean toothbrushing frequency, the largest number of the male students who accounted for 55.2 percent brushed their teeth once a day on average, and the greatest number of the female students who represented 52.9 percent did that twice a day. As for the influence of their major, the largest group of the health-related majors who numbered 89(51.1%) brushed their teeth twice a day, and the greatest group of the health-unrelated majors who numbered 93(49.2%) did that once a day. The gaps between them were statistically significant(p<0.05). 2. As to the length of toothbrushing time by gender, it took more than two or three minutes for the largest groups of the male and female students that respectively numbered 96(76.8%) and 184(77.3%) to do toothbrushing(p<0.01). The greatest groups of the male and female students that respectively numbered 72(57.6%) and 183(76.9%) brushed their teeth after meals. 3. In regard to oral hygiene supplies, the largest groups of the health-related and health-unrelated majors that respectively numbered 78(44.8%) and 115(60.8%) had chewing gum and candy with them. As to the use of oral hygiene supplies, 99 health-related majors(56.9%) and 133 health-unrelated majors(70.4%) didn't put oral hygiene supplies to use. Thus, the use of oral hygiene supplies was statistically less common among the health-unrelated majors, and the gap between the two was significant(p<0.01). 4. As for health-related concern by gender, the largest group of the male students that numbered 56(44.8%) showed the most interest in preventing dental caries, and the greatest group of the female students that numbered 103(43.3%) were most concerned about tooth whitening. The gap between the male and female students was statistically significant(p<0.05), but the track of their major made no statistically significant difference to that. 5. Regarding the experience and awareness of scaling, the largest number of the students never got their teeth scaled regardless of gender and major, and the greatest group didn't care about scaling irrespective of gender and major, either, though they considered it advisable to do.

This study examined the oral health-related quality of life of the elderly using the oral health index and dental prosthesis status, and explored methods to improve the oral health status. The data collected from 'The fifth Korean national health and nutrition examination survey 2010' were analyzed. The subjects were 2273 elderly people, aged 65 years or older, who had completed an oral examination, health questionnaires and nutrition examination. Statistical analysis was done using the SPSS 22.0 for Windows. Frequency analysis, multiple regression analysis and structural equation model were used for statistical analysis. The general characteristics, oral health index and dental prosthesis showed differences in the subjective oral health status associated with as age, ST, FS-T, T-Health, maxillary crown needs, maxillary denture needs, mandibular denture needs, chewing status associated with the income level, FS-T, maxillary crown needs, maxillary denture needs, mandibular denture needs, speaking status associated with the ST, T-Health, maxillary implant status, and maxillary denture needs. In conclusion, both the oral health index and dental prosthesis needs affect the oral health related quality of life of the elderly. Governments should implement a variety of oral health programs and dental prosthesis policies to improve the quality of life related oral health of the elderly.

The purpose of the study was to investigate nutritional status of chronic obstructive pulmonary disease (COPD) patients and to find out the differences according to the stages of disease. From March to October, 2006, 41 stable male patients of mild to severe COPD patients were recruited from Seoul National University hospital. The patients' of body weight and fat free mass were assessed by bioelectrical impedance analysis. The nutritional status of the patients was also assessed by 3-day recall, index of nutritional quality (INQ), dietary diversity score (DDS), dietary variety score (DVS), food group index pattern and dietary quality index (DQI). The total of 41 patients were classified into three groups, stage I, stage II and stage III groups according to the classification of Global Initiative for Chronic Obstructive Lung Disease (GOLD) standard. The mean age of the patients in each stage were 67.2-66.9 years showing no significant difference. The ratio of $FEV_1$/FVC were $57.5{\pm}7.3$, $46.9{\pm}7.6$ and $38.2{\pm}6.8%$, respectively showing significant differences according to the stages of disease. The fat free mass of the stage II ($48.2{\pm}4.7kg$) and III ($47.3{\pm}4.5kg$) was significantly lower than that of stage I ($53.1{\pm}6.9kg$) patients. There were significant correlation of fat free mass with $FEV_{1}$, and BMI (body mass index) with $FEV_{1}$/FVC ratio (p < 0.05). COPD patients showed the diet-related clinical symptoms of anorexia, dyspnea, dyspepsia, and chewing difficulty. Daily intakes of calorie, K, vitamin $B_2$ and folate of the patients were very low ($83.8{\pm}20.7%$, $58.9{\pm}14.4%$, $70.7{\pm}19.6%$ and $74.4{\pm}10.2%$, respectively) however, they did not significantly different according to the stages of disease. Daily intake of calcium was significantly lower in the stage III patients (p < 0.05). The mean scores of dietary variety score was significantly lower in the stage III patients (p < 0.001). Dietary quality index of the patients were not different among the stages of disease and the scores indicated poor quality of diet. As a summary, we found that body fat free mass, regularity of exercise, frequency of having snacks and dietary variety score were significantly associated with the severity of chronic obstructive pulmonary disease.

Objectives: This study aimed to confirm the correlation between oral frailty and health-related quality of life (HINT-8) among older adults in Korea. Methods: The data of 1,318 individuals aged ≥65 years who participated in the eighth Korean National Health and Nutrition Examination Survey (2019) were analyzed using complex sample statistical analysis. Results: Chewing discomfort was found to decrease the HINT-8 scores by 1.246, 1.324, and 1.089 times in the physical, social, and mental domains, respectively. Speech discomfort was found to decrease the HINT-8 scores by 1.275, 1.449, and 1.175 times in the physical, social, and mental domains, respectively. The HINT-8 scores of participants with ≤19 natural teeth were lower in the physical and social domains. Similarly, the HINT-8 scores of participants with brushing frequency of ≤2 were lower in the positive health domain. Non-use of oral hygiene products led to a reduction in the HINT-8 score in the social health domain. Conclusions: Oral frailty in older adults reduces the health-related quality of life. Thus, it is necessary to formulate policies to manage oral frailty in this population and develop specialized programs for the management of oral frailty.

This study was designed to determine the effect of gestation housing and parity on the farrowing performance and behaviour of sows during pregnancy, farrowing and lactation periods. Total 18 Duroc sows were randomly assigned after 4 weeks of gestation to either an individual gestation stall or a groups of three with pen gestation system for three parities(1st, 2nd${\sim}$3rd, and 4th${\sim}$5th). Approximately 7 days before predicted farrowing date, sows were transferred to farrowing crates where they remained until 21 days post-partum. Behaviour was recorded on day 60 and 90 of pregnancy for 24 hours, on day of farrowing for farrowing duration and on day 10 of lactation for 2.5 hours in the farrowing crate. The results obtained from this study were summarized as follows: On 60 and 90 day of pregnancy, all sows in both groups made attempts for ventral lying more than for other postures. Sows in the group gestation pen spent more time on walking than those in individual gestation stall(p<0.01); however, the group housed sows were spent less time on drinking than the individually housed sows(p<0.01). There was no significant difference between gestation housings in the occurrence of stereotypy of pregnant sows. On day 60 of pregnancy, sows in the individual gestation stall showed the highest frequency of vacuum chewing and head weaving. However, floor licking and bar licking behaviours were highest in day 90 pregnant sows individually housed. The sows individually housed during the gestation period spent more time on sitting and eating on the day of farrowing in the farrowing crate than the sows group housed. On day 10 of lactation in the farrowing crate, the group housed sows during the gestation period made significantly more attempts for ventral lying than sows individually housed. In conclusion, the occurrence of stereotypy of sows during the gestation and lactation did not differ between gestation housings and farrowing performance of sows during the gestation period was not affected by gestation housing. Thus, the group housing for pregnant sows is a feasible means to improve welfare of sows and to increase the normal behaviour of sows.

The present study was performed to analyze the life style and eating behavior of stroke patients and to find the risk factors related to stroke incidence in Daegu and Gyeongbuk Province, Korea. The case subjects (n=100) were selected from newly diagnosed stroke patients at Kyungpook National University Hospital. The control subjects (n=150) were selected from community inhabitants who did not have stroke history and were sex and age-matched with the case subjects. The survey was conducted by individual interviews using questionnaires on the general characteristics, life-style, eating behavior, food intake frequency and food preference. The high body mass index, preexisting diseases such as diabetes and hypertension, stroke family history, smoking, overeating habit and high preference for sweet, greasy and meat foods appeared to be the risk factors for stroke incidence. On the other hand, the results suggest that life style of regular exercise and nonsmoking, food habits of green tea drinking and enough chewing, preference for Korean meal type, high intake frequency for legumes, vegetables, mushrooms, seaweeds, fishes and shell fishes, soy milk and green tea might be the protective factors for the stroke. Therefore, maintenance of healthy weight, the prevention and management of the deteriorative chronic diseases, change of life style and improvement of eating behaviors are considered to be important for stroke prevention.
