Background: Insufficient training in infection control and occupational health among healthcare workers (HCWs) in countries with high human immunodeficiency virus (HIV) and tuberculosis (TB) burdens requires attention. We examined the effectiveness of a 1-year Certificate Program in Occupational Health and Infection Control conducted in Free State Province, South Africa in an international partnership to empower HCWs to become change agents to promote workplace-based HIV and TB prevention. Methods: Questionnaires assessing reactions to the program and Knowledge, Attitudes, Skills, and Practices were collected pre-, mid-, and postprogram. Individual interviews, group project evaluations, and participant observation were also conducted. Quantitative data were analyzed using Wilcoxon signed-rank test. Qualitative data were thematically coded and analyzed using the Kirkpatrick framework. Results: Participants recruited (n = 32) were mostly female (81%) and nurses (56%). Pre-to-post-program mean scores improved in knowledge (+12%, p = 0.002) and skills/practices (+14%, p = 0.002). Preprogram attitude scores were high but did not change. Participants felt empowered and demonstrated attitudinal improvements regarding HIV, TB, infection control, and occupational health. Successful projects were indeed implemented. However, participants encountered considerable difficulties in trying to sustain improvement, due largely to lack of pre-existing knowledge and experience, combined with inadequate staffing and insufficient management support. Conclusion: Training is essential to strengthen HCWs' occupational health and infection control knowledge, attitudes, skills, and practices, and workplace-based training programs such as this can yield impressive results. However, the considerable mentorship resources required for such programs and the substantial infrastructural supports needed for implementation and sustainability of improvements in settings without pre-existing experience in such endeavors should not be underestimated.

Objectives : This study was aimed to report the anti-wrinkle effects of cultivated wild ginseng pharmacopuncture. Methods : Data were collected from 23 patients who had been treated with cultivated wild ginseng pharmacopuncture for skin wrinkles. Patients were treated twice a week, for a total of 5 times. To observe the effect of the treatment, we measured the width and depth of skin wrinkles with ECOSKIN(portable fluorescent dermal diagnostic equipment). We also conducted a survey with patients to measure total satisfaction and the anti-wrinkle effect using a semantic differential scale. The evaluation was done 2 times, once before the first treatment and once 1 week after the last treatment. The relationship was measured by Wilcoxon signed rank test. Results : Skin wrinkle mean width decreased significantly from $9.45{\pm}6.60$ to $5.54{\pm}4.78$. Depth decreased significantly from $0.68{\pm}0.34$ to $0.39{\pm}0.24$ total satisfaction increased significantly from $2.46{\pm}0.743$ to $4.13{\pm}0.51$. Anti-wrinkle effect increased significantly from $2.46{\pm}0.63$ to $3.93{\pm}0.593$. Conclusions : These results suggest that cultivated wild ginseng pharmacopuncture may be effective for decreasing wrinkles.

Purpose: To investigate the efficacy of pregabalin for patients with primary burning mouth syndrome (BMS) who are unresponsive to topical clonazepam therapy. Methods: By searching the clinical electronic records from the Department of Oral Medicine, Pusan National University Dental Hospital from 2012 to 2014, a retrospective analysis was performed on patients with primary BMS who were treated with topical clonazepam therapy during this period. Of the patients who were unresponsive to this therapy, 19 patients who were subsequently treated with pregabalin were included in the study. A pain assessment was performed using the 11-point numerical rating scale at first visit, following topical clonazepam therapy, and again after pregabalin therapy. The treatment outcomes were statistically analyzed using the Wilcoxon signed rank test. Results: Following additional pregabalin administration, the mean pain score was slightly reduced. A total of 7 patients reported a marked response (>50% pain reduction), and 3 patients reported a slight reduction in pain. Pain reduction following pregabalin therapy was statistically significant (p<0.05). Conclusions: Pregabalin has a slight therapeutic effect on patients with primary BMS. Therefore, we recommend pregabalin as an alternative drug for BMS patients who are unresponsive to topical clonazepam therapy.

Objectives: Joint injuries frequently lead to progressive joint degeneration that causes articular disc derangement, joint inflammation, and osteoarthritis. Such arthropathies that arise after trauma are defined as post-traumatic arthritis (PTA). Although PTA is well recognized in knee and elbow joints, PTA in the temporomandibular joint (TMJ) has not been clearly defined. Interestingly, patients experiencing head and neck trauma without direct jaw fracture have displayed TMJ disease symptoms; however, definitive diagnosis and treatment options are not available. This study will analyze clinical aspects of PTA in TMJ and their treatment outcomes after joint arthrocentesis and lavage. Materials and Methods: Twenty patients with history of trauma to the head and neck especially without jaw fracture were retrospectively studied. Those patients developed TMJ disease symptoms and were diagnosed by computed tomography or magnetic resonance imaging. To decrease TMJ discomfort, arthrocentesis and lavage with or without conservative therapy were applied, and efficacy was evaluated by amount of mouth opening and pain scale. Statistical differences between pre- and post-treatment values were evaluated by Wilcoxon signed-rank test. Results: Patient age varied widely between 20 and 80 years, and causes of trauma were diverse. Duration of disease onset was measured as 508 post-trauma days, and 85% of the patients sought clinic visit within 2 years after trauma. In addition, 85% of the patients showed TMJ disc derangement without reduction, and osteoarthritis was accompanied at the traumatized side or at both sides in 40% of the patients. After arthrocentesis or lavage, maximal mouth opening was significantly increased (28-44 mm on average, P<0.001) and pain scale was dramatically decreased (7.8-3.5 of 10, P<0.001); however, concomitant conservative therapy showed no difference in treatment outcome. Conclusion: The results of this study clarify the disease identity of PTA in TMJ and suggest early diagnosis and treatment options to manage PTA in TMJ.

An inhaled salbutamol and salmeterol for chronic obstructive pulmonary disease(COPD) and asthma have been used worldwidely. But there has been few study about the voice change evoked from the post-medicine effect. To evaluate the voice influenced of short-acting and long-acting ${\beta}_2$-agonists, two experiments were carried out: one was salbutamol experiment 1 with eight patients, the other was salmeterol experiment 2 with six patients. Experiment 1 was made of two stages: premedication & postmedication. Experiment 2 was four stages: stageI was premedication, stageII was postmedication & pregaggling, stageIII was postmedication & postgaggling(100 ml with water), and stageIV was postmedication & 30 minutes later. Measured parameters were F0, F0_SD, Jitter_rap, Shimmer_apq11, HNR, BW(1, 2, 3), Intensity, and H1-H2. The mean data collected from 3 repetitions each was statistically analyzed by Wilcoxon signed rank test for experiment 1 and repeated measures ANOVA for experiment 2. In experiment 1, significant differences were found in the Jitter_rap(Z= -2.10, p=0.036). The findings indicated that the postmedicated voice was worse than premedicated voice. In experiment 2, there wasn't significant difference, but values of parameters related to voice quality(Jitter_rap, Shimmer_apq11, HNR, and H1-H2) showed changes toward stageⅣ, that is, the voice quality was worse under medication.

Objectives : This study was performed to investigate the change of bone mineral density(BMD) after 1 month Kirindiet therapy including very low calory diet(VLCD) in middle-aged obese women$(65>age{\geqq}40,\;BMI{\geqq}25)$ under normal $BMD(T-score{\leqq}0)$. Methods : We examined body weight, body fat, protein mass and BMD of 13 middle-aged obese women who visited to Kirin Oriental Hospital from Sep. 7. 2004 to Oct. 12. 2005 before and after 1 month Kirindiet therapy. Body weight, body fat and protein mass was checked by Inbody 4.0 and BMD was checked by quantitated computed tomography. Wilcoxon signed rank test was used for analyzing changes of body weight, body fat, protein mass and BMD before and after treatment. Results : Alter 1 month treatment body weight(-4.89Kg, -6.74%, p=0.001), body fat(-3.47Kg, p=0.001) and protein mass(-0.97Kg, p=0.006) was significantly reduced. BMD was significantly increased in all cases(+4.87mg/cc, +4.16%, p=0.001). Though body weight, body fat and protein mass were significantly reduced, BMD was significantly increased(p<0.01). Conclusions : In this study, we can conclude that after 1 month Kirindiet therapy including VLCD, BMD in middle-aged obese women under normal BMD was significantly increased inspite of reduction of body weight, body fat and protein mass.

Objectives : The purpose of 29 case series is to report the possibility that a hand acupuncture is effective in relieving headache. Methods : After approval from the Institutional Review Board (IRB), I analyzed 29 cases medical records of outpatients with headache, who visited ${\bigcirc}{\bigcirc}$ oriental medical hospital from December 2008 to December 2010, who have taken a hand acupuncture's treatment without other intervention, and who were diagnosed with one disease of international classification of headache disease second version (ICHD-2). The data was analyzed with Wilcoxon signed rank test to determine whether a hand acupuncture's treatment differed between before and after treatment's Visual Analogue Scale(VAS) according to types of headache and syndrome differentiation. Statistics program was used SPSS 18.0. Differences were considered significant at P<0.05. Results : The VAS of patients with headache was reduced after treatment of hand acupuncture from $6.57{\pm}2.04$ to $2.90{\pm}2.04$ for overall headache, from $6.32{\pm}2.05$ to $2.47{\pm}2.03$ for tension-type headache(P<0.001), from $7.10{\pm}2.18$ to $3.70{\pm}1.77$ for migraine(P<0.001), and from $6.00{\pm}1.41$ to $2.50{\pm}3.54$ for headache unspecified. A hand acupuncture produced a decrease in VAS of both ascendant hyperactivity of liver yang(P<0.001) and phlegm turbidity according to syndrome differentiation(P=0.002). No adverse event were encountered in any of the patients. Conclusions : It is suggested that a hand acupuncture may be effective in relieving headache, and could be applicable to first choice of acupuncture treatment for headache.

Objectives: The purpose of this preliminary study was to identify the nurses' perception regarding disclosure of patient safety incidents (DPSI) and to evaluate the effectiveness of education for DPSI. Methods: DPSI education was conducted for nurses majoring in clinical nurse specialist at an university. Before and after the education, the nurses made a questionnaire to evaluate the perception of DPSI. The questionnaires were divided into four categories: first, overall perception of the DPSI; second, recognition evaluation of the DPSI using hypothetical case, third, opinion on legal and nonlegal measures for facilitating the DPSI; and fourth, socio-demographic factors. The Wilcoxon signed rank test was performed on the DPSI questionnaire response to compare the perceptions before and after the education. Results: A total of 10 nurses participated in the education. DPSI education showed the possibility of improving the overall perception, necessity, effect, obstacle, and promotion method of DPSI, although there were also several responses where there was no statistical significance. In particular, DPSI education led to statistically significance change in the perception of obstacles for DPSI. For example, the number of respondents who agreed to the item "DPSI will increase the incidence of medical lawsuits." was 7 before education but decreased to 3 after education (P-value: .025) Furthermore, nurses' perception of DPSI from this study was generally positive regardless of education. Conclusion:In the future, it will be necessary to carry out DPSI education and training and to evaluate its effectiveness for more nurses.

Objective: This study was designed to investigate clinical features of chronic urticaria and assess Korean traditional medical therapy on that. Methods: The ratio of male and female, duration of symptoms, personal history and family history of allergic diseases, serum IgE level, and suspected causes and provocation factors were investigated in 41 patients with chronic urticaria. And frequency of wheals, duration of wheals, number of wheals, itch severity, and antihistamine counts of 6-point(0-5) score was assessed in 26 patients. The change of total scores between baseline and follow up were analyzed using Wilcoxon signed-rank test(p〈0.05). Results: 1. The ratio of male and female was 1:1.28 and the mean duration of symptoms was 26.0 months. 2. The frequency of personal history and family history of allergic diseases was each 53.7$\%$ and 48.8$\%$ and 30.6$\%$ had over 200 IU／mL serum IgE level. 3. The suspected causes were none(43.9$\%$), foods(29.3$\%$), drugs(9.8$\%$) and stress(7.3$\%$). 4. The suspected provocation factors were foods(39.0$\%$), none(19.5$\%$), fatigue(17.0$\%$), heat and sweating(l4.6$\%$), pressure(12.2$\%$) and stress(9.8). 5. The total scores between baseline and follow up of 26 patients was lowered from 14.85${\pm}$3.80 to 7.65${\pm}$4.31 and it was significant statistically. Conclusions: Korean traditional medical therapy was proved to be effective on the chronic urticaria and we need to consider foods as important factor in both treatment and patient education of urticaria.
