Purpose: Ventricular repolarization is assessed using the QT interval corrected by the heart rate (QTc) via an electrocardiogram (ECG). Prolonged QTc is associated with an increased risk of arrhythmias and cardiac mortality. As there have been few reports regarding the effects of hyperthyroidism on ventricular repolarization, we studied the association between serum free thyroxine (free T4 [fT4]) and thyroid stimulating hormone (TSH) levels and the QTc interval. Methods: Thirty-eight patients with hyperthyroidism (<30 years old) were included, and we used their clinical records and available ECGs (between August 2003 and August 2011) to evaluate the association between their fT4 and TSH levels and their QTc interval. In addition, we studied the ECGs of 72 age-matched patients with no hyperthyroidism (control group) and compared their data with that from the patients group. Results: The QTc duration in patients with hyperthyroidism was significantly prolonged compared to that in the control subjects (P<0.001). In addition, the number of hyperthyroid patients with abnormal prolonged QTc was significantly higher than that in the control group (P<0.001). Among the patients with hyperthyroidism, patients with prolonged QTc and borderline QTc had higher fT4 levels and there was positive correlation between their fT4 levels and their QTc interval (P<0.05). However, no correlation was observed between their TSH levels and their QTc interval. Conclusion: We report that hyperthyroidism is associated with QTc prolongation. The correlation between the fT4 levels and the QTc interval suggests that thyroid status is associated with QTc values and the risk of cardiac mortality.

Objective : This study is aimed to examine the degree of independence in stroke patients residing in a community based on their self-efficacy and Instrumental Activities of Daily Living and also correlation between community-residing stroke patients and their guardians by figuring out the life quality of their guardians. Methods : For total two weeks between May 12th and 23rd, 2014, this researcher collected data by using a survey (K-IADL, a scale to measure self-efficacy, WHOQOL-BREF) targeting 138 stroke patients who received over 24 points in MMSE-K among the outpatients of three hospitals located in Busan Metropolitan City and two hospitals located in Geoje-si, Gyeongsangnam-do, and total 125 sheets were finally used for analysis. Results : Among the 125 patients, 70 were males, and 55 were females, and their average age was 58.72 (16 to 82). The subjects' general self-efficacy (p<0.01) and detailed self-efficacy (p<0.01) indicated significant correlation with their guardian's life quality, and there was no significant correlation found between their Instrumental Activities of Daily Living and their guardian's life quality. Conclusion : Their general self-efficacy and detailed self-efficacy indicated correlation with their guardian's life quality, and among their general characteristics, the factor of their financial situation indicated correlation with their guardian's life quality. In conclusion, when stroke patients' self-efficacy is higher, their guardian's life quality increases, too, and if their financial situation is more favorable, their guardian's life quality gets higher. However, stroke patients' Instrumental Activities of Daily Living did not indicate correlation with their guardian's life quality. When looking at the chronic trend of outpatients, therapeutical plan must be established about the self-efficient recovery for the development of those who are not satisfied.

This study was to investigate the level of serum lipids and obesity in housewives in Mooan, and relationships between them. The average age, height and weight were 51.1 years, 154.3cm and 58.3kg respectively. The level of obesity of subjects was higher than that of housewives in other areas investigated in other studies. BMI and RBW underestimated in the obese compared to BIA. The amounts of lean body mass and total body water of subjects above 60 years old were smaller than those of forties and their BMI and RBW were lower than those of forties. However, their body fat percentage was nearly same as that of forties. Serum HDL-cholesterol(HDL-C) of subjects was lower than 55mg/㎗, the lower limit of normal range. Triglyceride of subjects above 60years old was higher than the 95th percentile of those of the same age with reference to Mayo clinic. The serum total cholesterol(TC) showed positive correlation with LDL-cholesterol(LDL-C) and TC/HDL-C(p<0.001). LDL-C showed positive correlation with TC(p<0.001), but negative correlation with HDL-C(p<0.05). HDL-C showed negative correlation with triglyceride(p<0.05). TC/HDL-C showed a positive correlation with triglyceride(p<0.05). HDL-C was the serum lipid which showed the highest correlation with obesity and body composition. It showed a negative correlation with the percentage of body fat(p<0.001), total body fat(p<0.001), BMI(p< 0.05) and RBW(p<0.05). TC/HDL-C showed positive correlation with the percentage of body fat(p<0.01) and total body fat(p<0.05). As the result of above, it is needed to make more researches to find out the proper method to estimate the obesity of subjects and educate subjects in Mooan about nutritional information for obesity.

Air pollution problems in Korea are gradually becoming a higher concern due to various reasons such as fine dust, causing anxiety among people with regard to their health. Although various studies have been carried out on the relationship between the influence of fine dust and a certain disease, they are mostly focusing on the analyzation that fine dust is related to specific illnesses such as respiratory and cardiovascular diseases, hypertension and diabetes. In this paper, we utilize the public data of medical history information to extract ten medical care subjects with the highest number of monthly care in 2016, and analyze the relation of fine dust with certain medical subjects using Pearson correlation coefficient. We also subdivide and analyze the correlation between fine dust and the medical subjects according to their gender and age. Middle-aged Female group with the strongest positive correlation between fine dust and the medical subjects is analyzed with the correlation from 2011 to 2015, with its relevance coefficient extracted by regression analysis in order to predict the correlation with the medical subjects according to the fine dust concentration.

Objectives : The purpose of this study was to examine the subjective awareness and expectations of implant patients. Methods : The subjects in this study were 200 implant patients at three different dental clinics in the region of Busan. Results : Concerning awareness of implant, the patients aged between 41 and 50 were best aware of implant with 2.85(p<0.05). By education, those who received college or higher education were best aware of it with 3.53(p<0.001). By income, those whose income was three million won or more were best aware of it with 2.95(p<0.05). As for expectations for implant, the women expected more from it with 2.89(p<0.01). By age, those aged between 41 and 50 had the biggest expectations with 3.63(p<0.001). By education, the patients whose income ranged between 2 and 2.99 million won had the greatest expectations with 2.91(p<0.05). Education and occupation made no significant differences to that. In regard to correlation among their knowledge, awareness and expectations for implant, there was a positive correlation between their knowledge and awareness(0.439), and their awareness had a negative correlation to their expectations(-0.147). Conclusions : The above-mentioned findings suggested that what patients expect from implant should accurately be grasped when counseling is provided, and that accurate information should be provided to them as well. Their cooperation should be requested during implant treatment, and special post-care programs should be prepared to boost their quality of life after receiving implant treatment. Quality medical services should be offered in proportion to the cost of treatment in order to satisfy their expectations.
