Formaldehyde (FA) is an important industrial chemical, but it can cause allergic reactions, sick building syndrome and so on. It has also been observed to cause cancer in scientific studies using laboratory animals, and it even causes cancer in humans. Natural products such as ginseng and pine needle containing complicated mixtures of organic chemicals are widely used in the world, because their effective components are responsible for some pharmacological activities including antioxidative effect, anticancer effect. We investigate the effect of Korean ginseng (GE), pine needle extract (PE) and combined GE and PE (cNPE) on mouse lung injury by FA exposure. GE, PE and cNPE was directly transported to pulmonary cells through respiratory organ by nebulizer inhalation. In the case of FA exposure, the pulmonary structure was damaged and its function became abnormal. However, cNPE-FA, GE-FA, and PE-FA treated groups showed similar with the control group compared with FA group. Among them, GE was proved to be more effective than any other extracts. These results demonstrate that natural product extracts could protect pulmonary structure and function against FA exposure.

본 연구는 빅데이터를 활용하여 투자 및 육성지원이 지역내총생산에 미치는 영향력을 다중회귀분석을 이용하여 분석하였다. 지역내총생산(GRDP)은 각 지역의 생산규모·지출수준·소득수준·산업구조 등을 집약적으로 내포하고 있는 지수로써, 지역경제 분석 및 국가의 정책수립에 활용하는 중요한 자료이다. 국가의 주요 국정과제를 올바르게 수행하기 위해서는 지역경제를 정확히 파악하는 것이 선행되어야 하는데, 이로 인해 최근 지역내총생산에 대한 관심이 급격히 증가하고 있다. 특히 해외투자는 투자유치국의 경제에 미치는 영향력이 상당하여, 이에 대한 많은 실증분석이 이루어지고 있다. 본 연구에서는 해외투자 및 국내육성지원이 지역내총생산에 미치는 영향력을 상관분석과 다중회귀분석을 실시하였으며, 그 결과 전체적으로 투자와 지원이 지역내총생산에 긍정적인 영향을 미친다는 결론을 도출하였다.

Purpose - This study focused on the effect of counter-factual thinking on post-purchase behavior producing consumer regret at HMR selection and purchase. We have analyzed the factors that HMR production and distribution businesses should consider because distribution and marketing strategy reflecting consumers' demand. Research design, data, and methodology - For the purpose of carrying out this research, we conducted a direst structured questionnaire to students at 'J' college. A total of 237 valid questionnaires were collected for students and their parents at 'J' university. For the hypothesis test, exploratory factor analysis, t-test, regression and structure equation path analysis were performed. Results - The consumers who often resented HMR purchase did counter-factual thinking on post-purchase behavior were likely to do switching purchases. Counter-factual thinking on post-purchase behavior had a negative influence upon consumer's satisfaction with HMR safety and marketing characteristics. Conclusions - Consumers who had been satisfied to a certain degree might have cognitive dissonance of minor mistakes of HMR product were likely to have downward counter-factual thinking through contrast effects. Therefore, HMR producer and distribution businesses that had production, distribution and marketing strategy to satisfy consumers by raw material, freshness and safety were likely to switch to another product at one time mistake of selection, purchase and use.

Angiogenesis is known as a crucial process in the growth and spreading of tumor cells. Accordingly, the effective inhibition of this process would appear to be a promising way to cure angiogenesis-related diseases, including cancer. This study demonstrates that acalycixenolide E (AX-E) from the marine organism Acalycigorgia inermis exhibits a potent anti-angiogenic activity both in vitro and in vivo. AX-E inhibits the bFGF-induced proliferation of HUVECs in a dose dependent manner, along with the bFGF-induced migration, invasion, and tube formation of HUVECs. Moreover, AX-E potently inhibits the in vivo neovascularization of the chorioallantoic membranes (CAMs) of growing chick embryos. interestingly, AX-E suppresses the expression of metalloproteases 2 and 9, yet shows no effect on their activities. The novel chemical structure and potent anti-angiogenic activity of AX-E will be of great value in elucidating the molecular mechanism of angiogenesis as well as in the development of a novel anti-angiogenic drug.

In order to fabricate 8YSZ thick film by silk screen printing, YSZ(yttria-stabilized zirconia) commercial powder was used as starting materials. Paste for screen printing was made by mixing 8YSZ powder and organic vehicles. 8YSZ thick film was formed on $Al_2O_3$ substrate. The crystal structure, and microstructure were investigated. Grain size of 8YSZ was increased with increasing calcination temperature and rapid grain growth was shown after calcination at $1300^{\circ}C$. Microstructure showed the mixture of large and small grain size after $1400^{\circ}C$ sintering. Shrinkage rate of 8YSZ thick film sintered at $1400^{\circ}C$ was more than 40%.

The purposes of this study were to examine the conceptual structure of shopping value, evaluative criteria of golf wear and store choice behavior, and to investigate the effect of shopping value and evaluative criteria of golf wear on store choice behavior. Data were obtained from 415 men and women aged 20-60 who had purchased golf wears living in Busan. The results of the study were as follows: Shopping value were composed of Hedonic shopping value and Utilitarian shopping value, and evaluative criteria of golf wear were consisted of Size/design.quality, Fitness/appropriateness of use, and Fashionability/brand. Stores choice behavior were composed of Atmosphere/salesperson, Diversity of product/service, Display/assortment, and convenience of location. Hedonic consumers tended to consider the price and display/assortment when they chose golf wear stores, and they were more likely to consider display/assortment mediated by fashionability/brand. But utilitarian consumers perceived less important diversity of product/service when they chose golf wear stores. Consumers who chose golf wear depending on fittness/design and quality patronaged stores offering diverse product/service.

Natural products decursin and decursinol angelate were recently reported as benign fungicides for controlling rice blast. Inspired by the structural similarity of the cumarin compounds and gained hint from the skeletal motifs, we designed and prepared synthetic compounds to increase the natural product efficacy and evaluated their antifungal activities against various plant disease pathogens in vitro. Synthetically prepared compound 4 and 5 indeed suppressed the mycelial growth of B. cinerea, F. oxysporum, P. italicum, and R. quercus-mongolicae. Additionally, compound 5 effectively prevents the growth of C. coccodes and C. parasitica. Furthermore, both 4 and 5 possess better inhibitory activities on spore germination of F. oxysporum and M. oryzae than the natural product decursin. These results suggest that the effect of the lead compound for plant disease protection can be improved by tuning the structure of the original natural product and decursinol chloroacrylates 4 and 5 are candidates for the control of F. oxysporum and M. oryzae.

비닐 아세트산염 합성에 대한 1족 알칼리금속 아세트산염의 촉진 효과를 조사하였다. Pd-Au/$SiO_2$ 촉매를 사용한 경우와 사용하지 않은 경우에 대해 에틸렌과 아세트산 간의 기체상 반응에 대해 생성물 선택성과 에틸렌 전환을 비교하였다. 촉진제가 촉매 표면을 안정화시켰으며, 생성물 선택성과 에틸렌 전환을 촉진하였다. 이 촉매 효과는 1족에서 위에서 아래로 내려갈수록 증가하였다. 이것은 아세트산염의 공통이온효과 때문이다.
