In preparative anti-corrosive coating experiments, polyaniline was obtained by reacting an oxidizing agent with the monomer aniline. Further, the primer coating was prepared using a variety of widely-used materials such as urethane resin. For the top coating, epoxy resin and acrylic urethane resin were used. Characteristics of the coatings were assessed according to KS and ASTM specifications, and the structure of the polyaniline was characterized using FT-IR and TGA. For analysis of anti-corrosive properties in salt-spray experiments, measurements of the oxidation state of iron and surface atomic analysis were conducted using XPS and SEM-EDX. Unlike general anti-corrosive coatings which exhibit anti-corrosive effects only as a primer coating, the anti-corrosive coatings using polyaniline as the anti-corrosive pigment showed a marked synergistic effect with the top coatings. In other words, the top coatings not only produce a fine view effect, but also increase, through interaction with the primer coatings, the resistance to diffusion of corrosive factors from the external environment. It was also found that, unlike the heavy metal oxide-forming layer of the passive barrier alone, the polyaniline anti-corrosive pigment oxidized iron at the interface with the iron substrate to form a passive barrier in the oxidic layer, and itself formed a potential barrier layer with anti-corrosive factors from the external environment. Although the passive layer was damaged, the damaged area did not become completely oxidized iron; on the contrary, it showed a tendency to reduction. This can be interpreted such that a passive layer is formed again on the damaged area, and that at the same time there is a tendency to self-healing.

Objectives : We aimed to determine therapeutic effects of probiotics-fermented Magnolia denudata(MD) in the allergic rhinitis model mice. Methods : Polyphenol production, DPPH radical scavenging activity and NO inhibition of fermented MD by different bacterial strains were evaluated to select the one that is most suitable for fermentation. Thirty C57BL/6 mice were divided randomly into 5 groups as follows: normal group, ovalbumin(OVA)-treated plus water fed(CON group), OVA-treated plus unfermented MD fed(UMD group), OVA-treated plus fermented autoclaved MD fed(A-FMD group) and OVA-treated plus fermented unautoclaved MD fed(FMD group). After 9 weeks, we observed changes in the blood cell count, OVA-specific IgE level, nasal rubbing, nasal mucosal tissue and body weight. Results : Extract of MD fermented by Bifidobacterium breve(BB) for 48 hours showed the highest anti-oxidant activity and anti-inflammatory activity out of all the other bacterial strains. The number of eosinophil count in A-FMD, FMD group and platelet count in FMD group showed statistically significant decrease(p<0.05). OVA-specific IgE level decreased in all 3 experimental groups, significantly in UMD and A-FMD group. Nasal symptoms were attenuated in all 3 experimental groups, statistically significant in A-FMD and FMD group (p<0.05). Histologically, infiltration of eosinophils into the nasal mucosa decreased in all 3 experimental groups, especially marked decrease in FMD group. Conclusions : According to the above results, it is considered that probiotics-fermented Magnolia denudata has inhibitory effects on the allergic rhinitis animal models.

Back ground & Objectives : Bilateral sudden sensorineural hearing loss(SSNHL) is very rare disease. This is the first case report in the oriental medical literature. This study describes a case of bilateral SSNHL with incomplete recovery. Methods : We treated 1 patient who had SSNHL sequentially in both ears. He received oriental and western medical treatments for more than 2 weeks and measured the hearing recovery. For diagnosis on this case, pure tone audiometry was used. The degree of improvement was evaluated by Siegel's Criteria. Results & Conclusions : This patient discharged without hearing improvement. For bilateral SSNHL patients, the result of treatment is important for their qualities of life. But the recovery rate of hearing in bilateral SSNHL is lower than unilateral SSNHL. The oriental medical therapy had some theraputic effects on SSNHL and the theraputic effects on bilateral SSNHL requires further study.

송민경 ( Min Kyung Song ),장염려 ( Yanli Zhang ),김상혁 ( Sang Hyuck Kim ) 대한관광경영학회 2015 觀光硏究 Vol.30 No.5

본 연구의 목적은 국내 호텔기업의 경영성과 결정요인을 재무요인과 비용요인으로 구분하여 OLS 회귀분석과 분위수 회귀분석의 분석결과의 차이를 제시함으로써 국내 호텔기업의 경영성과수준에 따라 경영성과 결정요인을 측정하고자 한다. 본 연구의 표본은 53개의 국내특급호텔의 3년간 자료를 pooling하여, 총 유효 샘플 159개를 최종분석에 이용하였다. 본 연구의 분석결과를 살펴보면, 호텔기업의 경영성과 수준에 따른 결정요인의 규명을 위해 실시한 분위수 회귀분석 결과는 OLS 회귀분석 결과와는 차이점을 보였다. 비용요인들은 대부분의 경영성과수준에서 영향을 미치지 않는 것으로 나타났다. 그러나, 재무요인은 호텔기업의 경영성과에 영향을 미치나, 그 수준에 따라 영향관계에 차이가 있음을 보여주었다. 구체적으로 살펴보면, 경영성과수준이 낮은 호텔기업의 경우에는 안정성과 활동성비율이 경영성과에 영향을 미치는 결정요인으로 나타났으며, 경영성과수준이 중간인 호텔기업의 경우에는 활동성을 제외한 모든 재무요인이 영향을 미치지 않는 것으로 나타났다. 마지막으로 경영성과수준이 높은 호텔기업의 경우에는 유동성, 활동성, 성장성이 경영성과에 영향을 미치는 결정요인으로 나타났다. 결론적으로 경영성과의 결정요인으로 비용요인보다는 재무요인이 중요한 영향을 미치며, 경영성과 수준에 따라 그 결정요인이 다름을 밝혔다. The purpose of this study is to identify the determinants of hotel company’s business performance by different level of business performance using quantile regression analysis. In sum, 159 sample companies were gathered from secondary database, then collected data were statistically analyzed. The results of this study are as follows: First, the cost variables were not significantly related with hotel company’s business performance based on the quantile regression results. However, some financial variables were significantly related with hotel company’s business performance. This results implies that the financial variables were more important factors to hotel business performance than cost variables. Secondly, the determinants of hotel company’s business performance were differently related with different level of business performance. Thirdly, the quantile regression analysis provides more insights than the OLS regression into understanding hotel company’s business performance. These results would help each hotel companies could establish different business strategies to increase their business performance depending on the level of business performance.
