This study examined the relationship between oral health behaviors and in senior citizens to determine how to improve their happiness index. The subjects in this study were 260 senior citizens aged 65 years or older, who resided in North Jeolla Province. A survey was conducted from June 17 to 30, 2016. The happiness index of elderly people who brushed their teeth more often and had dental checkups on a regular basis was significantly higher (p<0.05). Evaluation of subfactors associated with quality of life related to oral health showed significant differences in functional disturbances according to gender, age, the presence or absence of a spouse, and the use or nonuse of dentifrice (p<0.05). Physical pain significantly varied with the presence or absence of a spouse, educational level, monthly mean allowance, and regular dental checkups (p<0.05); significant differences were found in psychological discomfort according to gender, tooth brushing frequency, and regular dental checkups (p<0.05). There were significant differences in declining physical capacity according to gender, age, educational level, and monthly mean allowance (p<0.05); waning mental capacity significantly differed with age, living alone or with another person, the presence or absence of a spouse, and regular dental checkups (p<0.05). The factors that influenced the happiness index in senior citizens were age, living alone or with another person, educational level, monthly mean allowance and the Oral Health Impact Profile score (p<0.05). The study showed that measures are needed to improve the quality of life and happiness index in elderly people, including the development of oral health programs for this population.

This study was aimed at evaluating the effect of red-yeast-rice supplementation on cholesterol-lowering and glucose control in subjects with impaired fasting glucose (IFT) or impaired glucose tolerance (IGT). We conducted a doubleblind, placebo-controlled study with 3 groups; placebo, low dose group (red yeast rice 210.0mg/capsule, 2.52g/day) and high dose group (red yeast rice 420.0mg/capsule, 5.04g/day), which were randomly assigned to subjects with impaired fasting glucose or impaired glucose tolerance. We measured fasting serum concentrations of total-, LDL-, HDL-cholesterol, triglyceride, glucose, insulin, free fatty acid (FFA) and 2 h oral glucose tolerence test (OGTT) before and after the supplementation. Both low dose and high dose groups had significant decrease in LDL cholesterol and atherogenic index (AI) compared with placebo group (p<0.05). Additionally, total and HDL cholesterol improved significantly in high dose group compared with placebo group (p<0.05). Fasting serum glucose decreased in test groups and increased in placebo group after intervention. However, it was not significant differences. In subjects which fasting blood glucose is more than 110mg/dL, fasting glucose had a tendency to decrease in high dose group (p<0.1) and Hemoglobin A1c (HbA1c) had significant decrease in low dose group (p<0.05), while insulin and HOMA-IR had a tendency to increase in placebo group after intervention. Mean changes of glucose related parameters (fasting glucose, insulin, HOMA-IR) compared with placebo group did not show significant differences. In conclusion, subjects with impaired fasting glucose or impaired glucose tolerance were significantly improved in serum lipid profile by red yeast rice supplementation without serious side effects. These are more effective in the case of a high dose. The effects of red yeast rice supplementation on glucose control were insignificant.

For this research, 27 out of 52 patients with chronic low back pain involving sacroiliac joint pain were classified into the experimental group to conduct pelvic exercise program and traditional physical therapies in parallel, and the remaining 25 ones were classified into the control group to only apply traditional physical therapies for 6 weeks. After that, their clinical samples were randomly extracted. Before the experiment, both of the experimental group and the control group had the Oswestry disability index test to see how big their pain was and their hip joint angles were analyzed during walking. After the post-test, finally, the results of the Oswestry disability index test and hip joint angles while walking before and after the experiment were compared between two groups to know the effect of pelvic stability exercise program. Within-group results and between-group results both displayed significantly reduced low back pain, and when comparing hip joint angles of the experimental group, there were differences between mid stance phase, terminal stance phase, pre swing phase and early swing phase of the right hip joint, and mid stance phase, terminal stance phase, pre swing phase and early swing phase of the left hip joint. In the control group, there were significant differences between mid stance phase, terminal stance phase and early swing phase of the right hip joint, and loading response phase, mid stance phase, terminal stance phase and pre swing phase of the left hip joint. as a result, pelvic stability exercise program is helpful to gait rhythm on stance phase and swing phase although effective to decrease Oswestry disability index including pain.

A descriptive research is studied to identify the physical factors affecting to cognitive function among elderly residents over 65 years old in a community. The data were collected from 352 participants as part of a health-related survey by home visits in Seoul in 2010-2012. Their cognitive function was measured using the Korean form of Hasegawa Dementia Scale(HDS-K) and the collected data were analyzed by using t-test, ANOVA, and multiple regression analysis. From the analysis, the prevalence rate of cognitive impairment was 13.6%. Elderly residents in a community showed different cognition levels by the status of age, change of weight, change of BMI, walking and flexibility exercise. Especially, the lowest cognition level was found in the normal BMI group with decreased BMI change by over 3. The factors influencing on cognition level of the elderly with normal BMI were age, change of weight, change of BMI, and walking exercise. The variance indicated 12.2% as their cognition level. Therefore, for preventing the cognitive impairment of the elderly that were rapidly decreased of BMI, we need the program to manage their nutrition and walking exercise.

Objectives : The aims of this study were to know the frequency and the nature of cognitive dysfunction in type 2 diabetics, and to reveal influencing variables on it. Methods : From eighty type 2 diabetics (42 males and 38 females), demographic and clinical data were obtained by structured interviews. Cognitive functions were measured using the MMSE-K (Korean Version of the Mini-Mental State Examination) and the Korean Version of the Montreal Cognitive Assessment (MoCA-K) tests. Severity of depression was evaluated by the Korean Version of the Hamilton Depression Rating Scale (K-HDRS). Results : 1) Among eighty type 2 diabetics, 13.75% were below 24 on the MMSE-K, while 38.8% were below 22 on the MoCA-K. 2) The total scores and subtest scores of the MoCA-K including visuospatial/ executive, attention, language, delayed recall and orientation were significantly lower in type 2 diabetics with cognitive dysfunction (N=31) than those without cognitive dysfunction (N=49) (p<0.001, respectively). 3) There were significant difference between type 2 diabetics with and those without cognitive dysfunction in age, education, economic status, body mass index, duration of diabetes, total scores of the K-HDRS, the MMSE-K and the MoCA-K (p<0.05, respectively). 4) The total scores of the MoCA-K had significant correlation with age, education, body mass index, family history of diabetes, duration of diabetes, total scores of the K-HDRS (p<0.05, respectively). 5) The risks of cognitive dysfunction in type 2 diabetics were significantly influenced by sex, education, fasting plasma glucose and depression. Conclusions : The cognitive dysfunction in type 2 diabetics seemed to be related to multiple factors. Therefore, more comprehensive biopsychosocial approaches needed for diagnosis and management of type 2 diabetes.

Objective : Sleep disorder caused by stress or disease to elderly currently. We tried to make clear constant exercise according to exercise intensity would have effect on sleep disorder in elderly using EEG and melatonin. Methods : Thirty subjects were over 65 years old who lived a senior facility in some parts. They were able to communicate and understand the purpose of the study. They also expressed their intension to participate actively in experiment. They should have alert consciousness and orientation about time, place, and people. Sleep disorder was assessed via below 6 hr total sleep time and Pittsburge Sleep Quality Index, which was satisfied with both of criterion at the same time. Exercises composed of low intensity walking, moderate aerobic exercise, and high intensity resistance strength. We used QEEG 8-System (LAXTHA Inc. KOREA) to check wave type and Polysomnograpy (Compumedics, Australia) to test quality of sleep. and Histologic features were observed by TTC (triphenyltetrazolium chloride) staining and H & E (Hematoxylin & Eosin) staining. Results : There was a significant sleep index and change of melatonin after aerobic exercise. There was a significant SOL, S1, S2, and SWS in aerobic exercise, but there was a significant SWS in walking and resistance strength. There was a significant change of delta wave especially in frontal and temporal region between exercises. Conclusion : They had different effects according to type of exercise, when elderly who have chemical, behavioral change of circadian rhythms did exercise consistently. Aerobic exercise had more effect on sleep disorder than other exercise. Therefore, we may supply proper exercise to elderly and high quality of life.

Objectives : Face-to-face interviews were conducted to investigate the relationship between blood pressure and the impairment of cognitive function in rural elderly (N=932) aged 60-64 in Dalsung County, April to September in 1996 Methods : Impairment of cognitive function was defined as a score of less than 23 by the Korean version of the Mini-Mental State Examination (MMSEK). Blood pressure was measured once in each subject using a portable automatic sphygmomanometer. Results : By univariate logistic regression on males, no category of systolic blood pressure bore statistical significance. Groups with diastolic blood pressures of, less than 80 mmHg, 90-94 mmHg, and more than 95mmHg had odds ratios of more than one compared with the reference group (80-89 mmHg). This was most significant in the group with blood pressures lower than 80 mmHg, which had a statistically significant odds ratio of 1.68 (95% confidence interval CI; 1.02-2.75). No category of blood pressure was statistically significant in females. Multivariate logistic regression for males, with adjustment for age, educational attainment, smoking, alcoholic drinking, body mass index, atherosclerotic disease, and antihypertensive medication use, did not alter the odds ratios significantly in terms of systolic blood pressure. However, the group with diastolic blood pressure of less than 80 mmHg had an increased odds ratio of 2.01 (95% CI; 1.15-3.52) compared with the reference group. In females, systolic blood pressure did not alter the odds ratio, but the group with a diastolic blood pressure of less than 80 mmHg had a statistically significant odds ratio of 0.57 (95% CI; 0.37-0.89). Conclusions : These results suggest that the relationship between blood pressure and cognitive function status is stronger diastolic than systolic blood pressure and that there is a complex relationship between blood pressure and cognitive function by sex.

본 연구는 여성 갱년기장애에 대한 홍삼의 효과를 조사할 목적으로 수행하였다. 홍삼의 효과는 자연적으로 갱년기 장애가 유도되었다고 생각되는 자성 노령흰쥐를 사용하여 홍삼 조사포닌 분획을 투여(20mg/kg,b.w./day) 한 후 그 효괴를 조사하였다. 홍삼조사포닌 분획은 노령쥐의 체지방 축적으로 야기되는 체중 증가를 다소 감소시키는 것으로 관찰되었다. (p<0.01). 노령쥐는 젊은 쥐에 비해 혈중 당, 총콜레스테롤, BUN 함량이 증가하였는데 조사포닌 분획의 투여는 혈당, 총콜레스테롤 함량 및 BUN 함량증기를 유의하게 억제하는 것으로 나타났다. (p<0.05, p<0.01). 노령쥐는 노령화에 따른 간기능의 저하로 GOT 및 GPT 활성이 증가하였으나 사포닌의 투여는 GOT 및 GPT 활성증가를 억제하여 간기능을 젊은 쥐의 수준으로 회복시킴을 알 수 있었다. (p<0.01). 노령쥐의 대퇴골은 사포닌투여와 관계없이 현저한 무게차이가 관찰되자 않았으나 대퇴골중 무기이온 Na+ 함량은 사포닌 투여시 약 2배 증가하는 것으로 나타났다. 이러한 사실로부터 홍삼 조사포닌 분획은 노령쥐의 혈당, 총콜레스테롤, BUN 함량증가를 억제하는 효과를 나타내며 또한 노령화에 따른 간기능 관련 생화학 지수를 개선하는 것으로 사료된다.

Objective : The purpose of this study is to understand whether group Sensory Integration(SI) therapy has the effect on improvement of motor skill and social function for children with developmental disorder. Method : The subjects were recruited among children received sensory integration therapy at a Children's Development Institute in Dae-Jeon, experimental group is total 5 participating in group sensory integration therapy and control group is also 5 participating in individual sensory integration therapy. The program was constructed for 90 minutes and all children either in the experimental or in the control group went through intervention for 20 weeks. Bruininks-Oseretsky test of Motor Proficiency II, Korean-Scales of Independent Behavior-Revised and Social Maturity Scale were used in order to evaluate the degree of improvement in motor skill and social function. Results : Most children in the experimental group showed improvement in overall aspects of motor skill and the social function comparing pre-intervention with post-intervention, but they did not show any statistically significant differences. However, comparing experimental group with control group, children in the experimental group showed improvement in motor skill and social function. Furthermore, there is statistically significant improvement especially in manual coordination, manual dexterity, and social age and social quotient in Behavior-Revised and Social Maturity Scale. Conclusions : It is found that a group Sensory Integration therapy program has effect on motor skill and social function for children with developmental disorder in this study. In the future study, group SI therapy should be applied for children with diverse diagnosis in order to generalize the effectiveness of therapy.
