Purpose: This study was done to identify predictors differentiating the preparation stage, which is the stage that the smoker is ready to quit smoking, between adolescent smokers and adult smokers. Method: A survey was conducted with 376 adolescent smokers in 4 high schools and 451 adult smokers in community settings in South Korea from August 2003 to April 2005. To identify the predictors before and after preparation in stages of change of smoking, logistic regression was done. Results: The predictors for before preparation in stages of change of smoking were process of change for smoking abstinence for adolescent smokers and depression for adult smokers. The predictors for after preparation in stages of change of smoking were self-efficacy for smoking abstinence for adolescent smoker and self-efficacy for smoking abstinence and smoking temptation for adult smokers. Conclusion: For each group, adolescent smokers and adult smokers, specific smoking intervention methods need to be developed based on the different ways individuals make the decision to quit smoking within their contexts.

This study was conducted to evaluate sanitary practices of employees in business & industry foodservice operations of Pusan and the Kyung Nam areas, and to suggest a guideline for an effective sanitation training program. The questionnaire was used in this study as a survey method. Questionnaire were administered to 246 employees. The results were as follows. 55.3% of employees have had regular(monthly) food sanitation education. The mean rating of food sanitary knowledge for all employees was 65.9/100. When the education level was higher and the age younger, the mean rating of was also higher. Among the ratio of correct answers for food sanitary knowledge areas, a equipment sanitation was the highest (80.5%), and time temperature was the lowest(45.3%). The mean rating of sanitary procedures for food storage was 4.80/5.00, pre preparation 4.04/5.00, personal hygiene 3.54/5.00, equipment sanitation 3.20/5.00, and food preparation 2.56/5.00. Employees regularly educated in food sanitation rated significantly higher for food preparation than those who were of irregulary educated. The higher mean rating group(over 66) for the food sanitary knowledge showed significantly higher rates in sanitary procedures(food preparation, equipment sanitation, and personal hygiene) than that of the lower group(below 65). The practice of personal hygiene was positively correlated (p<0.001) with sanitary concept and food preparation, among the food sanitary knowledge areas.

Purpose: Learning physiological concepts and their practical applications in the appropriate contexts remains a great challenge for undergraduate medical students. Hence the present study aimed to analyze the learning experience of undergraduate medical students during an active learning process of 'preparation of models' depicting physiological concepts. Methods: A total of 13 groups, involving 55 undergraduate medical students with three to five individuals in each group, were involved in model preparation. A total of 13 models were exhibited by the students. The students shared their learning experiences as responses to an open-ended questionnaire. The students' responses were analyzed and generalized comments were generated. Results: Analysis of the results showed that the act of 'model preparation' improved concept understanding, retention of knowledge, analytical skills, and referral habits. Further, the process of 'model preparation' could satisfy all types of sensory modality learners. Conclusion: This novel active method of learning could be highly significant in students' understanding and learning physiology concepts. This approach could be incorporated in the traditional instructor-centered undergraduate medical curriculum as a way to innovate it.

In this study, the Ni-based catalysts for the production of synthetic natural gas were prepared by various preparation methods such as the co-precipitation, precipitation, impregnation and physical mixing methods. The ranges of the reaction conditions were the temperatures of 250~$350^{\circ}C$, $H_2$/CO mole ratio of 3.0, the pressures of 1 atm and the space velocity of 20000 $ml/g_{-cat{\cdot}}{\cdot}h$. It was found that the catalyst prepared by precipitation method had higher CO conversion than the catalyst prepared by co-precipitation method. While the catalyst prepared by precipitation method had the formation of NiO structure, the catalyst prepared by co-precipitation method had the formation of $NiAl_2O_4$ structure. It was confirmed that Ni-based catalyst prepared by the physical mixing method had the lowest CO conversion because it was deactivated by the production of $Ni_3C$ during the methanation. As a result, it was shown clearly that Ni-based catalysts prepared by impregnation method expressed the highest catalytic activity in CO methanation.

Objectives : This study is performed to investigate the therapy on tinnitus through the literature of Eastern and Western medicine. Methods : This study review the definition, etiology, classification, internal and external methods of treatment of tinnitus based on 50 articles of Eastern medicine, 16 articles of Western medicine about the treatment of tinnitus. Results : The results were as follows. 1. In Eastern medicine, the cause and mechanism of disease of tinnitus arose from the state of qi-blood deficiency, internal dampness-heat and depression stagnation. In Western medicine, there are mainly caused by damage to the auditory system the lower induced changes in the upper. 2. In Eastern medicine, differentiation of syndromes classifies clinical aspects, and cause and mechanism of disease. In Western medicine, it divides into an generating region, clinical and associated symptoms aspects. 3. In Eastern medicine, internal method of treatments of tinnitus are divided into four treatments. In Western medicine, internal methods of tinnitus are vasodilators, blood-flow improvers, Metabolism improvers etc. 4. In Eastern medicine, external method of treatments of tinnitus are paste preparation method, powder preparation method, pill preparation method, acupuncture & moxibustion method. In Western medicine, external method of treatments of Tinnitus are divided into injection, other surgical therapies and adjuvant therapy. Conclusions : Until now, there is no perfect, effective single treatment. We think that Eastern medicine approach and treatment can be helpful to overcome the limitations of tinnitus cure.

Diphencyprone (DPCP) is frequently used as a compounded preparation in dermatology for the treatment of alopecia and recalcitrant warts based on the immune reaction of skin allergy. However, DPCP is a non-recognized agent in Pharmacopoeia, because there are no criteria or analytical method for quality control of its powder and formulation. DPCP is unstable under light irradiation because as it easily decomposes to diphenylacetylene (DPA). This study aims to develop a simultaneous HPLC analytical method for analyzing DPCP and DPA in the raw materials and compounded preparation. The method required a C18 column ($250{\times}4.6mm$, $5{\mu}m$) at $40^{\circ}C$ with a mobile phase of (A) 0.01 M phosphoric acid in water and (B) acetonitrile at UV 220 nm. DPA conversion to DPCP in the powder and compounded preparations was accelerated after light exposure for 60 min. In addition, this resulted in different patterns depending on the wavelength of light and the formulation. That is, DPCP in compounded preparation was more unstable than that in the powder. However, the DPCP formulation in amber bottles was observed to remain stable, although the measured concentrations of DPCP were somewhat different from the nominal concentration of the compounded preparations. The control of the exact concentration is required for effective disease treatment, depending on the state of the patient. In conclusion, these results will be useful for the recognition of DPCP in Pharmacopoeia and new DPCP formulation development to prevent photodecomposition.
