Objectives: Periodontitis is multifactorial disease mainly caused by microbial community. Recently, some research has been conducted to find other possible risk factors including stress hormones related to periodontitis. Psychological stress can affect the periodontal health by a variety of biological mechanisms. This study compared the stress hormone levels in healthy subjects and patients with periodontal disease using saliva in order to investigate the association between periodontitis and stress. Methods: The human saliva was collected from 38 periodontally healthy individuals and 34 patients with chronic periodontitis under Institutional Review Board. Their age was 20-60 years ($40.3{\pm}10.45$). From these samples, determination of salivary levels of cortisol and Dehydroepiandrosterone (DHEA) performed by enzyme immunoassay kit (Salimetrics Europe, Suffolk, UK). The independent t-test and Mann-Whitney test for trend was applied using IBM SPSS statistics version 12.0 Program to analyze statistically significant differences. Results: Salivary cortisol levels of periodontitis patients were higher than those levels of healthy subjects (P < 0.001), while salivary DHEA levels of periodontitis patients were not significantly different (P = 0.431). Salivary cortisol/DHEA ratio of periodontitis patients was higher than those levels of healthy subjects (P < 0.001). Conclusions: Our study demonstrates the high levels of cortisol concentrations and cortisol/DHEA ratio in saliva of periodontitis patients than those of healthy subjects. Since cortisol levels and cortisol/DHEA ratio can be significant factors related to the severity of periodontal disease, our study would be helpful for early diagnosis and treatment of periodontal disease.

I examined the isokinetic knee extension mean torque in 30 patients with hemiplegia and 30 healthy subjects matched by age, sex, height, and weight at knee extension velocities of $30^{\circ},\;60^{\circ},\;90^{\circ}$, and $120^{\circ}$/sec. The purpose of this study is as follows: first, to compare isokinetic data between the involved and uninvolved side of patients and healthy subjects. secondly, to determine whether the relative decreases in knee extension mean torque at velocities greater than $30^{\circ}$/sec were different on the two sides. Mean torque of quadriceps on both sides of patients with hemiplegia was significantly less than the mean torque of muscle of healthy subjects at various speeds. Relative decreases in knee extension mean torque differed between speeds, but not between sides. Torque at speed greater than $30^{\circ}$/sec were correlated significantly with the torque at $30^{\circ}$0/sec. These finding indicated that isokinetic testing can provide objective information about quadriceps muscle performance in hemiplegia, and suggested that hemiplegia may have difficulty in moving forcefully at higher speeds than $30^{\circ}$/sec because they are weak. Therapeutic intervention, therefore, might be most beneficial when they are directed toward helping patients with hemiplegia activate their muscle weakness.

Purpose: The aim of this study was to determine the effects of lower rib cage lateral expansion limitation on the maximal inspiratory and expiratory pressures and on abdominal muscle activity during maximal respiratory breathing in healthy subjects. Methods: Fifteen healthy male subjects voluntarily participated in this cross-sectional study. During maximal breathing, maximal inspiratory and expiratory pressures were measured, and abdominal muscle activity was determined with using surface electromyography. Also, the measurement was repeated with using a non-elastic belt to the lower rib cage for limiting of lateral expansion. A Wilcoxon signed-rank test was performed for obtaining the statistical difference with a significance level of 0.05. Results: The findings of this study are as follows: 1) There were no significant differences in maximal inspiratory and expiratory pressure with and without lower rib cage lateral expansion (p>0.05), 2) There was no significant difference in abdominal muscle activity during the maximal inspiratory phase (p>0.05). However, right external oblique muscle activity decreased significantly during maximum exhalation with lower rib expansion limitation (p<0.05). Conclusion: The results of the current study indicate that a non-elastic belt was effective in decreasing right external oblique muscle activity during forced expiratory breathing in healthy subjects.

To elucidate alteration of peripheral T cell subsets in thyroid tumors, the author enumerated T cell subsets in periphral blood by indirect immunofluorescent method, using monoclonal antibodies (CD3, CD4 and CD8) in 17 cases of thyroid cancer, 12 cases of thyroid adenoma, and 16 cases of adult healthy subjects as controls. Diagnoses were confirmed histopatologically in thyroid cancer and adenoma, and were established on the basis of commonly accepted clinical and biochemical criteria in Hashimoto's thyroiditis. The blood was drawn from veins of the patients and control subjects in Pusan National University Hospital during the period of January to October 1990. The results obtained were summarized as follow: 1) The percentage of CD3+ cells was significantly decreased in thyroid cancer as compared with healthy subjects. 2) The percentage of CD4+ cells was not different among thyroid cancer, thyroid adenoma, Hashimoto's thyroiditis and control subjects each other. 3) The percentage of CD8+ cells was significantly decreased in thyroid cancer as compared with adult healthy subjects, and tended to be decreased as compared with thyroid adenoma and Ha-shimoto's thyroiditis. 4) The CD/CD8 ratio was significantly increased in thyroid cancer as compared with control subjects, and tended to be increased as compared with thyroid adenoma and Hashimoto's thyroiditis. On the basis of the results, it can be suggested that the immunodysfunction may be due to decreased soppressor/cytotoxic T cells in thyroid cancer.

Purpose: This study assessed the differences in the forward head posture (FHP), cervical range of motion, and headache clinical parameters in episodic tension-type headache (ETTH) subjects, chronic tension-type headache (CTTH) subjects, and healthy controls (university students). Methods: Fifteen CTTH subjects, 15 ETTH subjects and 15 controls without headache were examined. Side-view images of each group were taken in both the sitting and standing positions, in order to assess the FHP by measuring the craniovertebral angle. The CROM was used to measure the cervical range of motion. A headache diary was kept for 4 weeks to assess the headache intensity, frequency, and duration. Results: The craniovertebral angle was smaller, ie, there was a greater FHP, in the CTTH and ETTH subjects than in the healthy controls in both the sitting and standing positions (p<0.05). The CTTH and ETTH subjects showed a lower cervical range of motion than the healthy controls in the total range of motion as well as in the half-cycles (p<0.05). Conclusion: The increased FHP and decreased cervical range of motion might be a contributing factor in the initiation of tension-type headache.

This study evaluated the satisfaction and healthy eating index of nutrition-plus program providing nutritional supplements to pregnancy, lactating women, infant and children. This program was carried out at Public Healthcare Center, Seodaemun-gu in Seoul from February 2014 to June 2014. The subject selected among applicants for low income family financing of the government included 159 subjects. There was no statistically significant difference for degree of satisfaction with supplementary food by age, but the degree tends to get higher at lower age. Degree of satisfaction with supplementary food by the duration for participation was shown higher as the duration gets longer. For questions of 'Do you check nutrition label?' and 'Do you preserve food as described at food label?' in healthy eating index evaluation, the scores appeared higher at younger age group as they check the nutrition label more. Also as the duration for participation gets longer, the scores appeared higher which can be interpreted as effect of nutrition education from Nutrition-Plus. Frequency of having breakfast gets lower at higher age of subjects. And it gets higher as the duration for participation gets longer even though that there's no difference between '3 to 4 months' and '5 to 8 months' of the duration of participation. For evaluation of food security in recent 1 year, 86.8% of subjects responded 'Food sufficiency' and 'Enough but not always the kinds of food we want', and there is no difference by age and the duration of participation. As a result of this research, it is shown that the subjects of nutrition support project are relatively satisfied with the support. And healthy eating index gets improved as the duration of participation gets longer which can be considered as effect of nutrition education. It seems to be necessary to keep nutrition education as well as food support so to perform food life education on appropriate purchase and consumption of food.

Purpose: This study was accomplished to apply and to evaluate the 10-week Urinary tract Function Promotion for the Elderly Women (UFPE), and to suggest guideline and to be utilized on the community level. Method: Subjects were 30 persons of 16 healthy elderly and 14 hemiplegic elderly. This UFPE was composed of diagnosis of incontinence & evaluation of physical condition, understanding of urogenital system & urinary incontinence management. UFPE was evaluated by subjective urinary condition, intra-vaginal contraction power, continence self-efficacy (CSE), incontinence stress, geriatric depression. The collected data was analyzed using Wilcoxon Matched Signed-Ranks test by SPSS/WIN program. Result: 5 subjects (31.2%) in healthy group and 2 subjects(14.3%) in hemiplegic group have a daytime frequency, 14 subjects(87.5%) in healthy- group and 14 subjects(100%) have a nocturia. After program, subjective urinary condition was increased just only healthy elderly (Z=-2.545, p<0.05), while intra-vaginal contraction power and CSE were increased significantly only in the hemiplegic elderly (Z=-2.57, P<0.05: Z=-2.29, p<0.05). There were barriers not to comply program guidance such as inadequate perception of pelvic floor muscle, forget to do exercise, fatigue. Conclusion: UFPE was effective in increasing subjective urinary condition for healthy elderly and in increasing intra-vaginal contraction power and continence self-efficacy for the hemiplegic elderly women. I suggest that this UFPE be utilized at the health center and elderly center, and public health nurse counsel and guide the elderly's work through phone service.

Objective: The aim of this study was to evaluate the validity and reliability of using static surface electromyography (sEMG) on persons with neck pain and in healthy adults. Design: Cross-sectional study. Methods: Twenty-two female participants with neck pain and thirty healthy adults in the age group of 20-65 years were recruited in this study. To evaluate the validity and reliability of sEMG in subjects with neck pain, the subjects'characteristics were recorded and the Visual Analog Scale (VAS) and Neck Disability Index (NDI) were examined in addition to sEMG and algometer tests being carried out on the subjects. The site for using the sEMG and algometer was the upper trapezius. sEMG test-retest reliability was measured by intraclass correlation coefficients (ICCs). Independent t-tests were used to analyze the differences in the dependent variables between subjects with neck pain and healthy adults. The Pearson correlation coefficient was used to examine the linear relationship between measured variables. Results: sEMG and algometer tests were reliable according to the test-retest reliability results in subjects with neck pain and healthy adults (ICC=0.815-0.979). The results of this study showed that there were significant differences in respect to age, VAS, sEMG and algometer tests between persons with neck pain and healthy adults (p<0.05). The VAS and NDI were statistically correlated with sEMG and algometer results (p<0.05). Conclusions: In this study, we investigated the clinical usefulness of the static sEMG test in evaluating the pain scale of persons with neck pain with high reliability and validity.
