Background: This study aimed to examine the factors that influence clinical performance of dental hygiene students to provide useful data for developing strategies to improve clinical competence. Methods: The effects of variables on clinical competence by quantile level were analyzed using quantile regression analysis in 247 dental hygiene students. Quantile regression and multiple regression analyses were conducted using the Stata 11.0 program to analyze predictors of clinical competence. Results: The clinical competence score of dental hygiene students was 42.69±5.90, the satisfaction of clinical practice was 49.90±7.44, the clinical practice stress was 50.62±7.37, and the professional self-concept was 31.68±4.41. Empathy was the highest at 50.87±4.93. Multiple regression analysis showed that school year, stress from clinical training, satisfaction with clinical training, professional self-concept, and empathy had significant impact on clinical competence. Quantile regression analysis showed that the effects varied depending on the clinical competence level. School year and professional self-concept had a significant positive effect, regardless of the clinical competence level, while empathy had a significant positive effect at the top 10% (Q90) of the clinical competence level. Satisfaction with clinical practice affected clinical competence at Q25, Q50, and Q90. Stress from clinical practice had significant effects at Q25, Q50, and Q90 (p<0.05). Conclusion: According to the study results, different factors affected clinical competence according to the quantile of clinical competence. This study provides valuable implications for designing clinical competence enhancement programs and strategies. In addition, objective indicators for considering factors that may affect the clinical competence, such as academic competence and satisfaction of practice hospitals, are expected to require detailed analysis and measures.

personal nitrogen dioxide(NO$_2$) exposures for 31 professional drivers were measured using passive sampler and time activity diary in Asan and Chunan area, and were estimated using time-weighted average model. Mean concentrations of driver’s indoor and outdoor were 24.7$\pm$10.7 ppb and 23.3$\pm$8.3 ppb, respectively with indoor/outdoor of 1.1. Mean personal NO$_2$ exposure was 30.3$\pm$9.7 ppb. Personal NO$_2$ exposures were strongly correlated with indoor car NO$_2$ levels ($R^2$=0.80) rather than residential indoor NO$_2$ level ($R^2$=0.55). and outdoor NO$_2$ level ($R^2$=0.50). The driver’s NO$_2$ exposure using LP-gas with 24.4$\pm$8.0 ppb were statistically different from those using diesel with 36.3$\pm$14.1 ppb(p<0.01). The effect of driver’s smoking for personal NO$_2$ exposure was not found. It was considered that the main NO$_2$in driver is transportation. Since drivers mostly spent their times in indoor and inside car, time-weighted average model could be used to estimated personal NO$_2$ exposure using time activity diary, Though we did not measure all microenvironments, the estimated personal NO$_2$ exposures with 26.9$\pm$10.2 ppb were statistically correlated with measured personal NO $_2$ exposures30.3$\pm$9.7 ppb ($R^2$=0.89). The mean and standard deviation of personal NO$_2$ exposure using Mote-Carlo simulation were 26.6$\pm$7.2 ppb.

Allii sativi Bulbus(garlic) have been shown to possess medicinal value, in particular, antimicrobial activity. In this study, we compared the efficacy on some pathogenic bacteria and fungus among several different extracts(water, hexane, ethyl acetate, methanol, chloroform) of Allii sativi Bulbus. Animal pathogenic bacteria and fungus(S. gallinarium: KCTC 2441, S. flexneri: KCTC 2361, E. cloacae: KCTC 2006, K. pneumonia: KCTC 2208, C. albicans: KCTC 1940) were used to test by measurement of minimum inhibitory concentrations(MIC) and disc diffusion. Allii sativi Bulbus were cut and mixed with water at 37℃ about 24 h and filtered, and several different solvents(hexane, chloroform, ethyl acetate, methanol) were respectively added to separate the fraction of each solvent. The antimicrobial(bacteriocidal) and antifungal effect were apparently shown from water extract, hexane and ethyl acetate extract against using strains(Staphylococcus gallinarium, Shigella flexneri, Enterobacter doacae, Klebsiella pneumonia, Candida albicans). Especially, the water extract showed the superior efficacy. And the clear zone size of water extract (11～27 mm) was greater than that of gentamycin, hexane extract and ethyl acetate extract against S. gallinarium. S. flexneri, K. pneumonia and C. albicans. Minimum inhibitory concentrations(MIC) of water extract appeared to around 2.0～7.5 ㎎/㎖ against S. gallinarium, S. flexneri, E. cloacae and K. pneumonia. The greater activity was shown by water extract because the MIC of water extract for C. albicans observed in very low concentration(<1.0 ㎎/㎖) compared to hexane(5.0 ㎎/㎖) and ethyl acetate(10.0 ㎎/㎖). Therefore, these results exhibited that water extract of Allii sativi Bulbus have stronger antimicrobial activity than hexane and ethyl acetate extract, and may be useful as topical medicine of superficial infections causing C. albicans as well as antifungal agents.

The purpose of this study was to investigate the effects of Houttuynia cordata Thunb and Oriental Herb Mixture Extract (HCTM) through anti-oxidation against the hepatotoxicity-inducing lipopolysaccharide (LPS) in HCTM and LPS-treated rats. HCTM of 100 mg/kg concentration was intraperitoneally administered into rats at dose of 1.5 ml/kg for 20 days. On the day 21, 1.5 ml/kg of LPS was injected 5 hours before anesthetization. The activity of superoxide dismutase (SOD) was measured in mitochondrial fraction and malondialdehyde (MDA), catalase (CAT), glutathione peroxidase (GPx) were measured in liver homogenate. LPS-treatment markedly increased the levels of MDA and significantly decreased those of SOD, CAT and GPx. But HCTM pretreatment significantly increased those of SOD, CAT and GPx by 86.9%, 57.2% and 72.7% respectively. Moreover HCTM pretreatment decreased the levels of MDA. These results showed the HCTM had the effects against the hepatotoxicity-inducing LPS in the anti-oxidation. This suggested that HCTM could be used for functional beverage.

Objectives: The purpose of this study is to understand the practices of the dental implant maintenance care according to knowledge and attitude toward dental implant in the dental service consumers. Methods: T-test, ANOVA, and cross tabulation were carried out to understand the knowledge and attitude toward the dental implant, the experiences of the treatments, and the practices of their maintenance care depending on the general characteristics and the oral-health education experience. The collected data were analyzed using by SPSS Windows Program 23.0. Results: The actual state of the implant maintenance care was revealed to be high in the use of oral care products with 83.9% and in the professional maintenance care with 86.0%. In terms of the implant-related experiences, the participation and the participation frequency in the professional maintenance care were resulted to be higher especially in those with more cases of surgical procedures and in those with more failure experiences. Examining the practices of management according to knowledge and attitude toward dental implant, the higher in knowledge and attitude led to the higher uses of oral care products. The periodically professional maintenance care was indicated to be received even if being taken high management cost. Conclusions: Effective education methods and programs are necessary to be developed and executed so that information and knowledge can lead the correct practices in the dental service consumers.

Lipopolysaccharide (LPS) induces the synthesis of several inflammatory cytokine, chemokine, NO and inflammation in the liver of rats. The purpose of this study was to investigate the preventive effects of Houttuynia cordata Thunb and Oriental herbs mixture extract (HCTM) against the hepatotoxicity-inducing LPS in the lipid metabolism. HCTM of 100 mg/kg concentration was intra-peritoneally administered into rats at dose of 1.5 ml/kg for 20 days. On the day 21, 1.5 ml/kg of LPS was injected 4 hours before anesthetization. The levels of glutamate oxaloacetate transaminase (GOT), glutamate pyruvate transaminase (GPT), total lipid, triglyceride (TG) and HDL-cholesterol (HDL-C) were measured in serum. LPS-treatment markedly increased the levels of GOT, GPT, total lipid and TG, and decreased the level of HDL-C. However, HCTM pretreatment decreased the levels of GOT, GPT, total lipid and TG by 76.8%, 55.48%, 34.04% and 76.21% respectively, and increased the level of HDL-C by 97.84%. These results showed that HCTM had the protective effect against the hepatotoxicity-inducing LPS in the lipid metabolism, and it suggest that HCTM could be used for functional beverage.

Recently sports injuries are increasing due to the development of sports leisure industries as well as the increase of exercising population, and the study for sports injuries is needed more than before. Then the author studied the reasons for injuries, incidence rate, sites and sorts of sports injuries for the middle and high school football players during one year period from Jan. to Dec. 1994. The study subjects were 319 middle and high school players in Pusan and the method was questionnaire method. The results were as follows; 1. The average injury rate due to football play was 3.3 times per person for the 319 subjects during the last one year, and it was highest in goalkeeper as 4.6 times by position. 2. 68 % of the subjects did not receive periodic health examination, 74.9 % wore body protectors. The sports injuries due to football play occurred most commonly in soil play-ground(79.6 %), during training(52.3 %), and in winter time(33.7 %). 3. The commonly occurred injuries by motion were coalition(39.2 %), tackle(12.9 %), dribble (11.4 %) in order; those by sorts were contusion(34.4 %), sprain (32.9 %), spasm(9.0 %) ; and those by body portions lower extremities(82 %), trunk(17.6 %), upper extremities(12.5 %). 4. The frequently used treatment area was home care as in 42.7 % ; treatment methods were physical therapy, acupuncture/moxacautery, rest, operation in order; choices of treatment method were recommendation by coach/manager, and that by medical professional was the lowest as in 2.2 %. 5. If sports injury occurred during play, coach or manager let the players take rest in 56.2 %, but emergent management by medical professional was done only in 1.9 %. The return to play was decided mostly by the player himself(52.8 %), but that decided by a doctor was only in 1.0 %. In conclusion, to lessen the sports injuries due to football play, annual physical check-up, strengthening of play rules, improvement of playground, conditioning exercise, regulation of body protectors, and preventive training for expected injuries behaviors should be done and the decision to return to play and emergent management should be done by a medical professional as well.

Purpose: This study is a descriptive research conducted for looking into the role awareness level. role conflicts, and job satisfaction among professional home care nurses in the field of hospital based home care nursing service. Method: 154 specialized home care nurses in 63 hospitals and clinics that are implementing home care programs were subject to the study. Result: 1. The level of role awareness among professional home care nurses was $4.47\pm0.41$ on average out of 5. 2. The average score for role conflicts was $3.87\pm0.61$ out of 5. 3. In terms of job satisfaction level. $3.33\pm0.71$ was scored out of 5. 4. It has been discovered that there are statistically significant positive correlations among role awareness level, role conflicts(r= .224, P= .005), and job satisfaction level(r= .166, P=.040), while a negative correlation was detected between role conflicts and job satisfaction level(r=-.210, P= .009). Conclusion: The level of role awareness among professional home care nurses in the field of hospital based home care nursing service was very high and job satisfaction level was high when the level of home care nursing antecedents was high and the organization structure of working place was independent. But the level of role conflicts coming out of the weakness of job-supporting system was high. So the realistic alternative such as the improvement of working environment by administrative, institutional support, is required to make up for this problem in the future.

Objectives: This study was conducted to evaluate the impact of a School-based Depression Awareness Education Program on depression knowledge and help-seeking orientation for adolescent. Methods: The students of two high schools were allocated to the intervention (n=221) or control group (n=223) in this cluster-randomized trial. The school-based depression awareness education was a 3-hour program. The intervention group received pre, post and follow up tests while the control group received pre and follow up tests after two months. Depression knowledge, attitude to friends'depression, and help-seeking for professional assistance was evaluated at each test. Differences in the two month change between the intervention and control groups were analyzed by t-test or chi-square test. Results: There were positive changes in depression knowledge, response to friend's depression, and attitude to professional help-seeking in the post test compared to the pretest among intervention group. Improvement of depression knowledge was greater in the intervention group than in the control group (P=0.011), but there were no significant differences in response to friend's depression (P=0.268) or help-seeking orientation (P=0.263) after two months. Conclusions: School-based Depression Awareness Education resulted in significant positive changes in depression knowledge in high school students, but made no attitudes difference to professional help-seeking.
