Background: The study of conservative and surgical treatment of distal biceps tendinopathy and associated biceps tendon partial rupture. Methods: Twenty-one cases with distal biceps tendonitis and partial ruptures were studied who visited Pohang Semyeong Christianity Hospital from June 2010 to August 2017. The mean age was 57.1 years (39-69 years), 14 males and 7 females. The mean duration of symptom at the time of first visit was 4.9 months (0.2-14 months). Ultrasonography and magnetic resonance imaging were performed for patients with severe symptoms. According to the severity of the symptoms, splint immobilization, oral nonsteroidal anti-inflammatory drugs, and ultrasound-guided steroid injection were performed. Surgical treatment was performed if the patient did not respond to conservative treatment for 3 to 6 months or longer. Results: There were 9 cases of partial rupture of the distal biceps tendon associated with distal biceps tendinopathy on imaging studies. Conservative treatment showed symptomatic improvement in 16 of 21 cases. In 4 cases with a relatively mild symptom, anti-inflammatory analgesics and intermittent splinting showed good result. In 12 cases, symptoms improved after ultrasonography-guided steroid injection. Surgical treatment was performed on 5 cases that did not respond to conservative treatment. Conclusions: Conservative treatment of distal biceps tendinopathy may promise good results. However, in case of partial tear of the distal biceps tendon and refractory to conservative treatment, surgical treatment may be needed.

Objectives: Fatigue is a prevalent symptom encompassing both acute and chronic manifestations. Most fatigue symptoms can be cured by taking a rest or removing underlying causes. However, chronic fatigue is frequently problematic due to its duration and effect on quality of life. There are no particularly effective therapies for chronic fatigue of unknown causes, and patients in Korea usually visit an Oriental clinic. This study aimed to analyze the current status of treatments and patients with chronic fatigue, and then map out of a strategy for development of generalized-treatments for chronic fatigue in Oriental Medicine. Methods: Clinical information related to chronic fatigue was selected from various different databases such as PubMed, KoreaMed, KStudy, DBPIA, OIM, and KOMS. Also, to understand current tendency of medical examination and treatment related with chronic fatigue, we requested Health Insurance Review & Assessment Service for clinical datum from 2003 to 2007. Results: The medical fees of National Health Insurance related with fatigue show an explosive year-on-year increase. On the other hand, it has been decreasing annually in the western medical fields. To take charge of clinical fields related with chronic fatigue by Oriental Medicine, we should make a unified diagnostic system. Then, we should also make standard evaluation tools and develop herbal drugs according to this unified diagnostic system. Conclusions: Fatigue-related symptoms will be a main target of Oriental medicine in the future. We expect that various studies related with chronic fatigue will be undertaken hereafter.

Purpose: Surgical Site Infection(SSI) is the third most common cause of nosocomial infection, so that it results in serious socioeconomic impact such as extra hospitalization, mortality and health care cost. The aim of this study was to analyses the SSI that based on the degree of wound contamination and patient risk index after general surgery and to generate a reference data for the effective management and reducing SSI. Method: From July, 1999 to June, 2000, 1080 cases which presented with surgical site infection after general surgery at S hospital in chunchon city were included in this study. The data were collected by review of the medical records retrospectively. The collected data, in accordance with the test purpose, is analyzed by SPSS/PC+ program, using real numbers, percentage, $X^2$ test, Pearson's correlation and stepwise logistic regression. Result: The overall wound infection rate was 4.7%(51 cases out of 1,080). The infection rate of clean wounds was 1.4%. Surgical site infection rate for patient risk index scores of 0, 1, 2 and 3 was 1.9%, 8.0%, 13.1% and 20.0%, respectively and increased significantly according to patient risk index(p=.000). Sixteen of the fifty one(31.4%) surgical site infections were found during an outpatient visit after discharge. Multivariate analysis, identified two independent variables : duration of postoperation stay(p=.000), age(p=.037). The most frequent isolated organisms were Pseudomonas aeruginosa(21%) and Staphylococcus aureus(21%). Also Staphylococcus aureus were all MRSA(Methicillin Resistant S. aureus). Conclusion: In this study, SSI was analysed according to the degree of wound contamination and patient risk index after general surgery. The data that obtained from this study is expected that it would be available for surveillance and control of SSI.

Objective This study protocol aims to determine, using a rigorous approach in patients with bipolar disorder (BD) and non-seasonal major depressive episode (MDE), the characteristics of bright light therapy (BLT) administration (duration, escalation, morning and mid-day exposures) depending on the tolerance (hypomanic symptoms). Methods Patients with BD I or II and treated by a mood stabilizer are eligible. After 1 week of placebo, patients are randomized between either morning or mid-day exposure for 10 weeks of active BLT with glasses using a dose escalation at 7.5, 10, 15, 30 and 45 minutes/day. A further follow-up visit is planned 6 months after inclusion. Patients will be included by cohorts of 3, with at least 3 days of delay between them, and 1 week between cohorts. If none meet a dose limiting toxicity (DLT; i.e hypomanic symptoms), the initiation dose of the next cohort will be increased. If one patient meet a DLT, an additionnal cohort will start at the same dose. If 2 or 3 patients meet a DLT, from the same cohort or from two cohorts at the same dose initiation, the maximum tolerated dose is defined. This dose escalation will also take into account DLTs observed during the intra-subject escalation on previous cohorts, with a "Target Ceiling Dose" defined if 2 DLTs occured at a dose. Discussion Using an innovative and more ergonomic device in the form of glasses, this study aims to better codify the use of BLT in BD to ensure a good initiation and tolerance.

Purpose: This study aimed to identify the relationship among musculoskeletal problems, sleep problems, and self-rated mental health of home-care workers. Methods: Data were collected from 447 home-care workers spanning three occupation types: life supporters for the elderly, home-visit caregivers, and life supporters for the disabled. Musculoskeletal problems, sleep problems, and self-rated mental health were assessed using structured questionnaires. Factors affecting self-rated mental health were analyzed using multiple regression. SPSS was used to test the mediating effects of sleep problems on musculoskeletal problems and self-rated mental health. Results: Among the general characteristics, the variables that showed significant differences in musculoskeletal problems were monthly income level, caring-related career duration, weekly working hours, and occupation type; and the variable that showed significant differences in self-rated mental health was occupation type. Among the occupation types, supporters for the disabled had the most musculoskeletal problems and the lowest self-rated mental health. Musculoskeletal problems among home-care workers had a direct negative effect on self-rated mental health and indirect negative effects on sleep problems. Conclusion: Measures are needed to reduce the differences in working conditions and health status among the occupation types of home-care workers. Considering the relevance between the health issues of home-care workers, the development of a carefully designed health promotion strategy is required.

제품에 대해 소비자들은 주관적인 심리적 거리감을 갖는다. 그리고 해당 제품에 대한 광고소구 효과는 소비자의 심리적 거리감에 따라 달라질 수 있다. 본 연구는 해석수준이론을 바탕으로, 심리적 거리에 따라 효과적인 광고소구가 무엇인지를 분석하고, 아이트래커를 활용하여 신경 생리 실험을 하였다. 실험 참가자는 동일한 제품에 대하여 두 가지 소구유형의 광고를 모두 보았고, 7점 척도를 통해 각각의 광고를 평가하였다. 연구 결과, 심리적 거리가 가까운 제품일 때 이성소구를 선호하며, 심리적 거리가 먼 제품일 때에는 감성소구를 선호하는 것으로 확인되었다. 또한 눈의 움직임은 선호소구와 비선호소구를 보았을 때의 차이를 보였고 측정 변수로는 시선방문횟수(VC), 응시횟수(FC), 응시시간(TFD)을 사용하였다. 선호하는 소구를 보았을 때 세 변수 모두 비선호 소구를 보았을 때보다 값이 작게 나오는 것을 확인했다. 결론에는 본 연구가 갖는 학문적 시사점과 실무적 시사점, 그리고 연구의 한계점에 대해 논의하였으며, 향후 연구방향을 제시하였다.
