Background: The appropriate use of drugs is very important for a healthy life, as appropriate medication must be taken correctly for successful treatment of a disease. The purpose of this study was to investigate the self-efficacy between health status and drug abuse behavior. Methods: The subjects of this study were selected from 15 workshops located in Seoul, Incheon, Daejeon, and Chungnam, and, convenience sampling was conducted for each employee between September, 2017 and October 2017. A total of 204 questionnaires were analyzed. The questions evaluated health status, self-efficacy, drug abuse behavior, and general characteristics. Results: First, there was no difference in health status according to the general characteristics of the subjects. The self-efficacy varied according to gender, educational background, and monthly income, but not by marital status and residence area. In addition, drug abuse behaviors differed according to gender, residence area, and monthly income, but not by marital status and education level. Second, drug abuse behavior negatively correlated with health status and self-efficacy. Third, regression analysis showed that the self-efficacy between the health status and drug abuse behavior had a partially mediating effect. Conclusion: In patients with poor health status, it is necessary to increase their self-efficacy to reduce reduce drug abuse. Therefore, regular education programs targeting efficacy and drug knowledge are required in the community.

Objective : The purpose of this study was to identify characteristics of patients' self-perceived health in traditional Korean medical facilities. Method : This research was conducted based on the survey on patients whom have visited traditional Korean medical facilities in 2011 by the Ministry of Health and Welfares and Korean Institute for Health and Social Affairs. Using a sample of 3,931 (1,180 male and 2,751 female) outpatients' self-perceived health based on the data from usage and consumption of Korean Medicine. 'Healthy', 'Fair', and 'Poor Health' were used to measure patients' self-perceived health status. The data was analyzed by frequency, t-test, cross correlation analysis and multiple logistics regression analysis using the SPSS program package. Results : Sex(P<0.001), age(P<0.001), marital status(P<0.001), education(P<0.001), employment status(P<0.001), occupation(P<0.001), health insurance(P<0.001) and income level(P<0.0001) showed statistical significance. Main Treatment Facilities(P<0.001), experience of taking Korean medicine(P=0.032), experience of receiving acupuncture treatment(P<0.001), number of visits(P<0.001), medical expense (P=0.005), and subjective health status after the treatments showed statistical significance for Korean herbal medicine(P=0.038), acupuncture (P=0.001), cupping therapy(P=0.006), oriental physiotherapy(P=0.003), and treatment satisfaction(P<0.001). For subjective health status based on suffering disorders in the past three months, the response of poor health was higher in the group suffering recent illnesses. Statistical significance was seen in hypertension (P=0.002), arthritis(P<0.001), lumbar pain(P<0.001), diabetes mellitus(P=0.001), stroke(P<0.001), hwa-byung (P=0.001), gastric disorders(P=0.021), common cold(P<0.001), ankle sprain(P<0.001), muscular injury(P<0.001), lumbar sprain(p=0.009) and fracture(P=0.03). Also the number of diseases during the past three months showed statistical significance(P<0.001). Statistical significance was also seen in Level of knowledge(P<0.001), route of information(P<0.001), reliability of Korean medicine(P=0.003), insurance coverage(P=0.005), medical costs(P<0.001), and future willingness to use Korean medicine(P<0.001). As a result of the multiple logistics regression analysis, risks of subjective poor health statistically increased in female population, elderlies, medicaid beneficiaries, less educated, higher medical expense, and more disorders during the past three months. Conclusion : Patients' self-perceived health status has significant differences with each variables such as sex, age, marital status, education, health insurance, medical expense, number of diseases.

Coenzyme $Q_{10}$ ($CoQ_{10}$, or ubiquinone) is an electron carrier of the mitochondrial respiratory chain (electron transport chain) with antioxidant properties. In view of the involvement of $CoQ_{10}$ in oxidative phosphorylation and cellular antioxidant protection a deficiency in this quinone would be expected to contribute to disease pathophysiology by causing a failure in energy metabolism and antioxidant status. Indeed, a deficit in $CoQ_{10}$ status has been determined in a number of neuromuscular and neurodegenerative disorders. Primary disorders of $CoQ_{10}$ biosynthesis are potentially treatable conditions and therefore a high degree of clinical awareness about this condition is essential. A secondary loss of $CoQ_{10}$ status following HMG-CoA reductase inhibitor (statins) treatment has been implicated in the pathophysiology of the myotoxicity associated with this pharmacotherapy. $CoQ_{10}$ and its analogue, idebenone, have been widely used in the treatment of neurodegenerative and neuromuscular disorders. These compounds could potentially play a role in the treatment of mitochondrial disorders, Parkinson's disease, Huntington's disease, amyotrophic lateral sclerosis, Friedreich's ataxia, and other conditions which have been linked to mitochondrial dysfunction. This article reviews the physiological roles of $CoQ_{10}$, as well as the rationale and the role in clinical practice of $CoQ_{10}$ supplementation in different neurological diseases, from primary $CoQ_{10}$ deficiency to neurodegenerative disorders. These will help in future for treatment of patients suffering from neurodegenerative disease.

Purpose: We retrospectively analysed patients' dental and periodontal status according to the presence of non-communicable diseases (NCDs) and the effects of NCDs on periodontal treatment outcomes. Factors influencing disease recurrence were investigated using decision tree analysis. Methods: We analysed the records of patients who visited the Department of Periodontology, Pusan National University Dental Hospital from June 2014 to October 2019. As baseline subjects, 1,362 patients with periodontitis and who underwent full-mouth periodontal examinations before periodontal treatment were selected. Among them, 321 patients who underwent periodontal examinations after the completion of periodontal treatment and 143 who continued to participate in regular maintenance were followed-up. Results: Forty-three percent of patients had a NCD. Patients without NCDs had more residual teeth and lower sum of the number of total decayed, missing, filled teeths (DMFT) scores. There was no difference in periodontal status according to NCD status. Patients with a NCD showed significant changes in the plaque index after periodontal treatment. The decision tree model analysis demonstrated that osteoporosis affected the recurrence of periodontitis. Conclusions: The number of residual teeth and DMFT index differed according to the presence of NCDs. Patients with osteoporosis require particular attention to prevent periodontitis recurrence.

Background: The objective of the present study was to examine the status of patients who had received dental treatment under intravenous (IV) sedation at Chungnam Dental Clinic for the Disabled in Korea from its inception to the present time, and to review the analysis results. Methods: Retrospective analysis was performed on 305 cases of patients who had received dental treatments under IV sedation between January 2011 and May 2016. The analysis examined the patient's sex, age, primary reason for IV sedation, duration of anesthesia and dental treatment, type of dental treatment performed, number of clinical departments involved in the dental treatment and level of multidisciplinary cooperation, and annual trends. Results: Most dental treatments using intravenous sedation were performed on medically disabled patients or dentally disabled patients with an extreme gag reflex or dental phobia. The mean duration of IV sedation was 72.5 min, while the mean duration of treatment was 58.0 min. The types of dental treatments included surgical treatment (n = 209), periodontal treatment (n = 28), prosthodontic treatment (n = 28), restorative treatment (n = 23), implant surgery (n = 22), endodontic treatment (n = 9), reduction of temporomandibular joint dislocation (n = 1), and treatment of traumatic injuries (n = 1), with treatments mostly performed on adult patients. Conclusions: With increasing demand for minimally painful treatment, cases using IV sedation are on an upward trend and are expected to continue to increase.

본 연구는 구강건강상태와 구강건강관리 행태에 따른 삶의 질을 측정하기 위하여 2013년 3월부터 7개월간 일부지역의 치과병 의원에 내원한 환자를 대상으로 구강검사 및 설문조사를 실시하여 최종 384명을 분석하였다. OHIP-14는 일반진료를 받은 환자에서 가장 높았고, 하위영역으로 기능제한 교정치료 8.27점, 신체적 동통 7.24점, 정신적 불편감 7.90점, 신체적 능력저하 7.79점, 정신적 능력저하 8.14점, 사회적 능력저하 8.24점 모두 일반진료에서 높았고, 사회적 불리에서는 교정치료(8.78)점으로 통계적으로 유의한 차이를 보였다. 성별에서는 모두 남자에서 높았고, 연령에서는 연령이 증가할수록 삶의 질이 나빠졌으며, 직업은 주부에서 대부분 낮게 나타났고, 전신질환이 없는 경우 삶의 질이 높게 유의한 차이를 보였다. 구강건강관리 행태에서는 정기검진을 받지 않고, 통증 시 치과내원이 가능한 경우 삶의 질이 높게 유의한 차이를 보였다. 구강건강상태에서는 실란트 시술을 받은 치아, 충전치료를 받은 치아와 상실치아, 보철치료를 받은 치아, 임플란트 식립 치아가 없는 경우 삶의 질이 높은 것으로 나타났다. 이상의 결과에서 개인의 삶의 질에 영향을 향상시키기 위해서는 개인의 구강건강관리 시스템구축뿐만 아니라 사회적으로도 예방진료와 구강보건교육을 바탕으로 관리시스템을 구축하여 자연치아를 오래 보존 하여야 할 것이다. 또한 이를 기초로 하여 삶의 질을 향상하기 위한 끊임없는 노력과 연구들이 이루어져야 하리라 생각된다.
