The purpose of this study were to evaluate and compare the balance ability at different conditions in normal 20 to 29 years old on unstable platform, KAT 2000(Breg, Inc., Vista, CA. 1994). Static and dynamic BI(balance index) were measured 3psi and 5psi surface conditions. Static tests were done on right and left leg separately, then both legs together with the feet apart 20cm with the eyes opened and closed. Dynamic tests were done on both legs together with apart 20cm with the eyes opened. A dynamic test was performed in which the subject moved platform in a circular manner to chase a moving object on a computer screen. Seventy healthy students(average 21.6 years, male, female) were tested. In this study applied the paired t-test and correlation to determine the statistical significance of result. The results were as follow: 1) The mean static balance index of the Rt leg was $119.9{\pm}75.72$ on 3psi surface condition with the eyes opened, and that of the Lt leg was $224.3{\pm}121.16$. 2) The mean static balance index of the Rt leg was $93.1{\pm}24.16$ on 5psi surface condition with the eyes opened, and that of the Lt leg was $180.5{\pm}61.76$. 3) The mean static and dynamic balance index of both legs were $76.4{\pm}31.86$, $2187.6{\pm}696.99$ on 3psi with the eyes opened, and $68.3{\pm}14.82$, $1938.7{\pm}525.41$ on 5psi respectively. 4) The mean static balance index of the Rt leg was $517.8{\pm}220.87$ on 3psi surface condition with the eyes closed, and that of the Lt leg was $588.6{\pm}204.81$. 5) The mean static balance index of the Rt leg was $271.9{\pm}192.151$ on 5psi surface condition with the eyes closed, and that of the Lt leg was $363.4{\pm}98.97$. 6) The mean static balance index of both legs was $332.6{\pm}137.31$ on 3psi surface condition with the eyes closed, and that of the 5psi was $288.5{\pm}133.07$. 7) The balance index on 3psi surface condition was significantly higher than that of 5psi (p<0.05, p<0.01). 8) The balance index with the eyes closed was significantly higher than that of the eyes opened (p<0.05). 9) The balance index on the left leg was significantly higher than that of the right leg (p<0.05, p<0.01). 10) There was no correlation between static balance index and dynamic balance index. 11) Therewas no correlation between weight or height and balance index.

Objectives: This study seeks to evaluate the vulnerability assessment of the human health sector for $PM_{10}$, which is reflected in the regional characteristics and related disease mortality rates for $PM_{10}$ in Busan over the period of 2006-2010. Methods: According to the vulnerability concept suggested by the Intergovernmental Panel on Climate Change (IPCC), vulnerability to $PM_{10}$ is comprised of the categories of exposure, sensitivity, and adaptive capacity. The indexes of the exposure and sensitivity categories indicate positive effects, while the adaptive capacity index indicates a negative effect on vulnerability to $PM_{10}$. Variables of each category were standardized by the rescaling method, and each regional relative vulnerability was computed through the vulnerability index calculation formula. Results: The regions with a high exposure index are Jung-Gu (transportation region) and Saha-Gu (industrial region). Major factors determining the exposure index are the $PM_{10}$ concentration, days of $PM_{10}{\geq}50$, ${\mu}g/m^3$, and $PM_{10}$ emissions. The regions that show a high sensitivity index are urban and rural regions; these commonly have a high mortality rate for related disease and vulnerable populations. The regions that have a high adaptive capacity index are Jung-Gu, Gangseo-Gu, and Busanjin-Gu, all of which have a high level of economic/welfare/health care factors. The high-vulnerability synthesis of the exposure, sensitivity, and adaptive capacity indexes show that Dong-Gu and Seo-Gu have a risk for $PM_{10}$ potential effects and a low adaptive capacity. Conclusions: This study presents the vulnerability index to $PM_{10}$ through a relative comparison using quantitative evaluation to draw regional priorities. Therefore, it provides basic data to reflect environmental health influences in favor of an adaptive policy limiting damage to human health caused by vulnerability to $PM_{10}$.

Mandibular advancement devices (MAD) are therapeutic options for obstructive sleep apnea (OSA). The aim of study was to investigate treatment outcomes of before and after insertion of MAD in OSA patients. We retrospectively selected a total of 13 patients who were diagnosed with OSA syndrome. All sleep-related parameters including apnea-hypopnea index (AHI), oxygen desaturation index (ODI), wake after sleep onset (WASO), total arousal were measured by before and after MAD. The use of MAD proves to be efficient in reducing snoring, apnea-hypopne index ($17.2{\pm}14.6$ vs $20.9{\pm}14.6$), WASO ($27.4{\pm}28.8$ vs $47.9{\pm}43.6$), oxygen desaturation index ($9.0{\pm}11.6$ vs $16.4{\pm}11.7$), stage N3 ($54.8{\pm}45.2$ vs $36.6{\pm}22.0$), REM sleep times ($73.3{\pm}19.4$ vs $66.0{\pm}31.0$) and increases sleep efficiency ($92.6{\pm}6.6$ vs $87.2{\pm}11.2$). The decreases in apnea index based on a reduction in the overall and supine AHI values after MAD therapy were significantly greater for the positional OSA than nonpositional OSA patients. The use of MAD proves to be efficient in snoring, WASO, sleep efficiency, reduced AHI and associated with good compliance of patients.

This study was intended to assess the effects of low glycemic index (LGI) nutrition education on dietary management and glycemic control of patients with type 2 diabetes mellitus. The subjects were 48 sex-matched patients with type 2 diabetes mellitus, aged $66.5\;{\pm}\;6.2$ years, visiting a public health center. They were divided into two groups: the control group (males 10, females 14) and the educated group (males 10, females 14). The educated group was provided with a LGI nutrition education program for 7 weeks. The control group was educated only one time for general diabetic education. Anthropometric indices, knowledge and perception of efficacy of low glycemic index carbohydrates, dietary glycemic index (DGI) and glycemic load (DGL), fasting blood glucose, and HbA1c were assessed. In the educated group body weight, body mass index and systolic blood pressure (from $138.0\;{\pm}\;18.9\;mmHg$ to $130.6\;{\pm}\;15.0\;mmHg$) were significantly reduced after the nutrition education (p < 0.05). The scores of knowledge and perception of efficacy of low glycemic index carbohydrates increased significantly in the educated group. Dietary glycemic index and glycemic load of the educated group decreased significantly from $103.4\;{\pm}\;67.6$ to $45.4\;{\pm}\;27.1$ (p < 0.001), and from $173.3\;{\pm}\;135.9$ to $66.8\;{\pm}\;50.4$ (p < 0.001), respectively. Also fasting blood glucose and HbA1c levels of the educated group significantly decreased from $124.5\;{\pm}\;28.8\;mg/dL$ to $96.7\;{\pm}\;21.6\;mg/dL$ (p < 0.001) and from $7.1\;{\pm}\;1.3%$ to $6.4\;{\pm}\;1.2%$ (p < 0.05), respectively. The score of knowledge and perception of efficacy of low glycemic index significantly correlated with fasting blood glucose and HbA1c levels negatively. DGI, DGL and duration of diabetes significantly correlated with HbA1c level positively. From stepwise multiple linear regression analysis, DGI, DGL and the duration of diabetes were extracted as factors influencing HbA1c level of the subjects. The results of this study suggest that low glycemic index nutrition education programs is an effective intervention measure for the glycemic control in type 2 diabetic patients.

Objectives The purpose of this study is to compare the effects between the KL-Grade and improvement of knee pain treated by Korean Medicine therapy. Methods 114 patients who received inpatient treatment from July 2014 to May 2017 in the Daejeon Jaseng of Korean Medicine Hospital were divided into 5 groups by the KL-Grade. All patients received a combination of treatment including acupunture, pharmacopunture, herbal medication. They were compared and analyzed on the basis of improvement between measuring Numeric Rating Scale (NRS), Western Ontario and McMaster Universities Arthritis Index (WOMAC Index), EuroQol-5 Dimension Index (EQ-5D Index) as they were hospitalized and as they were discharged. The statistically significance was evaluated by SPSS 23.0 for windows. Results After treatment, KL-Grade 0 group's Numeric Rating Scale (NRS), Western Ontario and McMaster Universities Arthritis Index (WOMAC Index), EuroQol-5 Dimension Index (EQ-5D Index) improvement was $2.02{\pm}1.69$, $7.50{\pm}9.67$ and $0.11{\pm}0.15$ respectively. KL-Grade 1 group's improvement was $2.09{\pm}1.23$, $11.75{\pm}13.99$ and $0.12{\pm}0.13$ respectively. KL-Grade 2 group's improvement was $1.60{\pm}1.07$ and $14.70{\pm}14.19$ respectively. But In this group, EQ-5D Index has decreased by $0.01{\pm}0.10$. KL-Grade 3 group's improvement was $1.88{\pm}1.31$, $7.81{\pm}13.35$ and $0.13{\pm}0.20$ respectively (p<0.034). In the case of KL-Grade 4, the population was not statistically significant (N=2) and therefore excluded from statistical significance. And there was no statistically significance between 4 group's improvement after treatment (p>0.05). Conclusions The above study showed that Korean medicine treatments showed significant therapeutic effects on knee pain and degenerative knee joints, but there was no significant difference in the effectiveness of degenerative arthritis (KL-Grade).

The purpose of this study is to investigate the effects of thyroid hormone on the left ventricular(LV) volume arid function in man with untreated hyperthyroidism and to determine the effects of successful therapy for thyrotoxicosis on the ventricular pathophysiology. In the present study, equilibrium radionuclide cardiac angiography was performed and LV volume index, ejection phase indexes of LV performance, serum thyroid hormone levels and other hemodynamic parameters were measured in 28 normal subjects and 39 patients with hyperthyroidism before treatment and again every 4 weeks for the first 2 months after the initiation of effective therapy. The results obtained were as follows; 1) In the untreated hyperthyroid state heart rate, blood volume, cardiac index and stroke volume index($97{\pm}14$ beats/min, $73.5{\pm}11.8ml/kg,\;6.9{\pm}1.4\;l/min/m^2$ and $77.6{\pm}13.8ml/m^2$, respectively) were increased significantly compared to those in normal control($74{\pm}12beats/min$, $66.6{\pm}14.8ml/kg,\;3.8{\pm}1.2\;l/min/m^2$ and $56.6{\pm}13.2ml/m^2$ respectively). $(Mean{\pm}SD)$ 2) There was a significant increase in LV end-diastolic volume index in patients with hyperthyroidism ($30.5{\pm}7.5$ for hyperthyroid group compared to a normal control of $22.2{\pm}6.5$; p<0.001), whereas end-systolic volume index remained unchanged $9.6{\pm}3.6\;and\;8.8{\pm}3.3$ respectively).3) In patients with hyperthyroidism, LV ejection fraction was $70.0{\pm}5.6%$, fractional shortening $32.9{\pm}5.1%$, mean velocity of circumferential fiber shortening(mean Vcf) $1.34{\pm}0.31$ circ/sec and maximum ejection rate $3.47{\pm}0.80$. All the ejection phase indexes were significantly greater than those in normal control($65.2{\pm}5.7%,\;28.8{\pm}3.2%,\;0.88{\pm}0.37$ circ/see and $2.27{\pm}0.50$, respectively; p<0.001). 4) Effective therapy produced significant decrease in all the values of serum thyroid hormone concentrations(p<0.00l), hemodynamic parameters(p<0.001), end-diastolic volume index(p<0.01) and ejection phase indexes of LV contractility in patients with hyperthyroidism and after one to two months, when the patients were euthyroid, these measurements were in the range of normal. 5) A significant linear correlation between mean Vcf and serum thyroxine level(r=0.63, p<0.001) as well as between mean Vcf and serum triiodothyronine level(r=0.62, p<0.001) was found. The lesser degree of correlation was also noted between other ejection phase indexes and serum thyroid hormone concentrations. The results indicate that the major effects of excess thyroid hormone on the LV in human beings with hyperthyroidism are an enhancement of LV function and an increase in LV enddiastolic volume and that these effects cause predictable reversible cardiac alteration which are changed dramatically and immediately after effective therapy.

흉부방사선 영상의 평가는 시각에 의한 사진평가가 가장 실용적이고 효과적인 방법으로 알려져 있다. 미국 방사선 안전국 규정 평가표(Bureau of Radiological Health, BRH)는 흉부방사선 영상의 해부학적 평가와 물리적 평가를 합하여 평가하는 효율적인 영상 평가방법이다. 본 연구는 여성 351명의 흉부방사선 영상을 체질량지수(Body Mass Index, BMI)와 허리둘레, 관전류량(mAs)과의 관계를 비교하고, 미국 방사선 안전국 규정 평가표를 사용하여 흉부 방사선 영상품질평가를 시행하였다. 대상자의 평균 연령은 $30.17{\pm}4.73$세이고, 허리둘레는 평균 $66.91{\pm}4.67cm$이었다. 체질량지수 값의 평균은 $20.21{\pm}2.23$으로 나타났으며, 전체 대상자의 관전류량 평균값은 $3.04{\pm}0.78$이고, 미국 방사선 안전국 규정 평균값은 $79.83{\pm}8.45$이었다. 허리둘레가 커질수록 관전류량 값이 증가함으로 나타났으며, 체질량지수가 커질수록 mAs값도 증가하였다. 연구대상자의 허리둘레, 관전류량, 미국 방사선 안전국 규정 값은 체질량지수 값이 커지면 허리둘레와 관전류량 평균값이 증가하였고, 미국 방사선 안전국 규정 값은 체질량지수가 높은 그룹이 낮은 그룹에 비하여 상대적으로 낮게 나타났으며, 통계적으로 유의하였다. 흉부검사 시 피검자의 신체두께나 체질량지수에 따라 자동노출제어 장치의 노출제어가 적절히 잘 이루어진 것으로 생각되며, 체질량지수가 증가할수록 신체두께가 커지고 또한 여성의 유방 두께도 증가하여 자동노출제어 장치에 의한 노출량이 변화되어 영상품질에 영향을 미치는 것으로 생각되어진다.
