This study was conducted to verify the effect of the fall prevention exercise program (FPEP). From 1st June to 14th July in 2014, 52 subjects above the age of 65 in 2 health clinics of A town, J city were randomly assigned to two groups(exercise 31, control 21). While exercise group performed FPEP twice a week for 6 weeks, control group received education only. The results showed significant difference between the two groups in the TUG of physical function(P=.032). There were no statistically significant difference between the two groups in the fear of falls, falls efficacy of mental functions. The result of ultrasound measurement of lower extremity muscles showed statistically significant differences between groups in the 7 items(RF CSA Contraction RF DIS Resting, TA Thickness Contraction, TA P-angle Contraction, GCM Thickness Resting, GCM Thickness Contraction, GCM P-angle Contraction)(p<.05). In conclusion, the FPEP is very effective in the prevention of falls.

The moving behaviour of anchovy schools(There were small schools of sardine and round-herring in this anchovy schools} in the bag - net of a large scale set - net was investigated using a scanning sonar, in the Kishihata set - net fishing ground located in Nanao city Ishigawa prefecture, Japan from Dec. 1st to Dec. 4th, 1992. The results obtained are summarized as follows ; 1. Moving behaviour of fish schools between two bag - nets was more in the daytime than in the nighttime. 2. The rate of entering fish schools from the first bag -- net to the second bag - net were 78% when the fish school in the second bag -- net existed. The result suggest that fish school existence in the second bag - net affected the rate of entering fish schools from the first bag - net to the second- bag - net. However, the time of stay of fish school that entered the second bag -- net was very short when the fish school in the second bag - net existed densely. The result suggest that a high fish density in the second bag - net might enlarge the escape rate 3. The majority of fish schools moved to the center and off shore side of the bag - net when fish schools entered the bag - net.

This study was performed to investigate the physicochemical properties of Korean Citrus sudachi fruit which were harvested at different harvesting time(every 20 days from Sep. 3 to Nov. 8) and region(Seogwipo and Cheju city area). The average weight of Citrus sudachi fruit harvested from Seogwipo area was as twice as that of Cheju area at the same period. The moisture content in fruit peel increased by ripening of fruit, but that of fruit juice showed no difference. The content of reducing sugar in fruit peel and fruit juice increased 2 times from Sep. 3 to Nov. 8. The content of crude fiber decreased both in fruit peel and fruit juice as progression of ripening. Crude protein and ash contents decreased in fruit peel but revealed no differences in the fruit juice during the same period. pH decreased in fruit peel and juice with its ripening. The content of vitamin C decreased by ripening of fruit. The transmittance which is important quality factor in fruit juice increased from Sep. 20 to Oct. 13. The content of free sugar increased about 2 times in fruit peel from Sep. 3 to Nov. 8 and showed 4 times increase in fruit juice at the same period. In the composition ratio of mineral, Ca and K were abundant in the fruit peel, but only K was the most abundant mineral in fruit juice than any others.

Purpose: This study conducted a survey on the elderly of 65 years and over with physical debilities and ones capable of living at home residing in Jeju Special Self-Government Province to compare and analyze demo-sociological characteristics and factors influencing on oral health related living quality. And also this study intended to provide basic data for developing effective public medical policies and health promotion programs to increase oral health related living quality of the elder. Methods: The elderly of 65 years and over living in Jeju Special Self-Government Province were interviewed individually from 7 February 2011 to 18 April and interview results of a total of 220 subjects were analysed for this study. Results: Current status of the elderly including ones with & without physical debilities influenced functional limitation and behavioral aspects of GOHAI criteria used in this study. The elderly with physical debilities experienced less limitation in food chewing and swallowing, and pronunciation than ones capable of living at home. On the analogy of the previous study(by Park, N. G., 2010) in which oral health related quality and satisfaction of life of the elderly with physical debilities were different due to their physical, circumstantial and psychological limitations, the former's oral health conditions are worse than the ones capable of living at home and because of medical care accessability limitation they suffer from deteriorated oral condition. By the comparison of factors influencing on the living quality relating to the oral health of the elderly with physical debilities and ones capable of living at home, 2 factors, age and living area, were meaningful factors commonly influencing on the oral health related living qualities of both. The elderly of 75 years and over were more affected by psychological and behavioral aspects of oral health related living quality than the ones of 65-74 years, and the ones living in country suffered from functional limitations, pains and discomfort more than ones in city. Additionally, being different from the elderly capable of living at home, the ones with physical debilities were influenced by the factors of average monthly income and medical security type. Conclusion: Improvement of programs and systems to increase oral health related quality of life needs to be carried out preferentially for the elderly of 75 years and over, and dwelling in country. Also this study suggests that the policy of paying the denture insurance allowance in 2012 need effective planning considering the elderly's current status, age, living area, medical security type.

Background: Apolipoprotein E has been one of the most thoroughly studied genetic polymorphisms, particularly for its effects on lipid profiles and coronary heart disease risk. This study investigated the relationship between the apolipoprotein E polymorphism and essential hypertension in a Korean population. Methods: The subjects (n=1,243) were participants in a population-based study in Incheon metropolitan City, Korea. The apolipoprotein E polymorphism was determined using a polymerase chain reaction method. Results: The frequencies of the genotypes did not differ significantly between the hypertensive groups (60.0% ε2 / ε2, 30.8% ε2 / ε3, 44.4% ε2 / ε4, 33.3% ε3 / ε3, 32.3% ε3 / ε4, and 15.4% ε4 / ε4; p=0.498). After adjusting for other risk factors, genotypes were not associated with hypertension(OR 5.74, 95% CI 0.81-40.76, ε2 / ε2 vs. ε3 / ε3; OR 0.94, 95% CI 0.60-1.47, ε2 / ε3 vs. ε3 / ε3; OR 1.21, 95% CI 0.30-4.89, ε2 / ε4 vs. ε3 / ε3; OR 0.79, 95% CI 0.56-1.13, ε3 / ε4 vs. ε3 / ε3; OR 0.29, 95% CI 0.06-1.45, ε4 / ε4 vs. ε3 / ε3). Conclusions: These findings suggest that the apolipoprotein E polymorphism is not associated with hypertension.

Purpose: This study aimed to provide basic data for the development of an education program on diabetic foot prevention care for care helpers in long term care facilities. Additionally, it sought to determine care helpers' knowledge and practice regarding diabetic foot prevention care, and to identify the correlation between such knowledge and practice. Methods: This cross-sectional study employed a structured questionnaire. Participants consisted of 90 care helpers who were working in three long term care facilities in Jeju city. Data collection was conducted from September to November 2016. Results: The mean knowledge and practice scores were 8.77±1.28 (range 0~10) and 28.17±2.44 (range 10~30), respectively. Practice regarding diabetic foot prevention care was significantly different by care helpers' gender (t=-2.28, p=.024), period of career in the long term care facility (F=3.29, p=.025), and received education on diabetic foot prevention care (t=3.08, p=.005). A positive correlation was observed between knowledge and practice (r=.35, p<.001). Conclusion: To improve the practice of diabetic foot prevention care, specialized education programs that consider gender and period of career in the long term care facility as well as the improvement of the level of knowledge of care helpers on diabetic foot prevention care are needed.

This descriptive study explored the health and illness concepts of preschoolers to provide understanding on which to build research. The subjects were convenience sample three to six year of age attending one art institute in Cheju city. Data were collected through semistructured interviews by author, Children were asked to draw two figures, one healthy and one ill persons. The drawings were not analysed to grasp the meaning as in a projective technique, but only to relate to their response. Data were coded and categorized by content analysis. The results of this study are summarized as follows : 1) Three year olds responded with some unrelated answers but well to questions related to their experiences of illness ; older participants answered questions related health and illness concepts more easily. Generally the levels of subjects' responses did not differ according to age and sex. 2) Preschoolers' answers about the cause, treatment and prevention of illness, and the meaning and promotion of health were coded and then classificated to 9 categories, (food, obedience to authoritys physical function, presence or absence of illness or symptoms, hygiene. treatment, traumatic injury, rest and germs). Food and obeidence to authority categories were most frequent responses the food category was associated with obeidence to authority because it seemed that the children follow the orders of their parents or other authority figures to eat or not to eat something This result was compatible with that of previous studies that preschoolers perceived illness as possible punishment for misbehavior. Participants except for one four year old boy did not suggest that germs cause illness. The children perceived themselves and their families as healthy even though they had symptoms of illness. 3) Preschoolers' health and illness concepts were. influenced by their experiences and related to their development that rules derived from authority and if not complied with, will bring punishment. These oonceptualizations may be the disparity that they perceived themselves and their families as healthy even though they were ill. A previous study by Perrin and Gerrity suggested that the level of children's illness concepts correlated with that of their physical causality and was lower than it. But the levels of health and illness concepts in this sample higher than those of the physical causality.
