The purpose of this study was to identify the importance of information search during the trip in regional tourism in a positive way. There have been the studies relative to information search before the trip, however, relatively little research on information search during the trip even though these cases more occur in reality. Three hypotheses were formulated as follows: 1) The need for information during the trip will influence the levels of tourist information search in the region; 2) The levels of tourist information will influence satisfaction for information; and 3) The convenience between the levels of information search and satisfactions will function as moderating effect. The data of 208 international travelers leaving Jeju island after the trip were selected at Jeju international airport as the exit survey. As the results of analysis, three hypotheses were confirmed and academic and practical discussions were presented.

Objective : The purpose of this research is to examine the effect of Sa-am acupuncture treatment(Sim-seungkyuk) for major symptoms of Hwa-byung.Method : In this randomized, single blind, placebo-controlled study, we compared active acupuncture with sham acupuncture in the treatment for major symptoms of Hwa-byung. likert scale(5 score) for major symptom of Hwa-byung was measured as the 1st evaluative instrument, and STAXI-K, STAI-K, BDI-K and HRV were also measured as the 2nd evaluative instrument at the before treatment and after treatment.Results : 26 volunteers participated in this study by dividing two groups, each 13 persons in trial group and control group at random. In comparison of likert scale for major symptoms, after treatment the total score of likert scale for major symptoms decreased significantly in both group than before treatment. And after treatment, the total score of trial group decreased less than those of control group in comparison between two groups. especially after 2 weeks from all treatment, there was significant difference between two groups. Conclusion : We considered that Shim-seungkyuk of Sa-am acupuncture treatment will be not recommended to treatment of Hwa-byung because this study could not prove effect of Shim-seungkyuk treatment for Hwa-byung in spite of preliminary study. This study will be used to provide a fundamental data for development of clinical research as preliminary study of Hwa-byung.

The purpose of this study is to find out the problem of ineffective PR communication of the government that informs the destination of the tourism, and to draw the PR communication strategy that stimulates the visit demand substantially and to lay the foundation on the reasonable academic basis to support it. The construal level theory(CRT) focusing on the human cognitive process and behavior was examined and applied to the tourism phenomenon. As a research method, experimental design and experiments were carried out in order to rigorously control experimental variables such as participant recruitment and randomization of group distribution, experimental manipulation of independent variables and experimental situation. The results of this study provided evidence that the application of CRT to tourism phenomenon is valid through the research hypothesis test, and considering the effect of psychological distance on construal level, a basic clue was found.

The purpose of this study was to investigate perceived values of visitors according to tourist site types including nature, culture and human-made facility, and to find out the influences of perceived values to price fairness. There has been little research on this field relatively while some relative studies deal with price fairness in hotels and restaurants which have been relatively perceived commonly with their prices. Two hypotheses were formulated as follows: 1)There are differences on perceived values according to tourist site types and 2)There are influences of perceived values to price fairness differently. The valid data of 298 were collected in three different tourist sites including natural, cultural and human-made facilities as a main theme. The main results can be summarized as follows. Esthetic value was highest for natural tourist sites while emotional and functional values were highest for cultural sites, and novelty value was highest for human-made sites. There were the significant influences of esthetic and emotional values to price fairness for natural sites, the effects of esthetic, emotional, functional, and social values for cultural sites, and the effects of emotional, functional, and novelty values for human-made sites.

식물자원으로부터 생리활성 물질의 이용측면에서 국내에서 자생하고 있는 광나무 잎을 대상으로 하여 다양한 생리활성을 가지는 것으로 보고된 페놀성 화합물의 분포를 확인하였다. 총 페놀성 함량은 0.89~1.53%, 축합형 탄닌은 0.10~0.13%였으며, flavonoid는 aglycone인 apigenin, luteolin과 칼럼크로마토그라피를 행하여 분획으로 분리한 후 가수분해하여 이들의 배당체를 확인하였다. 페놀산의 분획 중 유리형 페놀산 화합물에는 tyrosol, t-cinnamic acid, p-hydroxybenzoic acid, vanillic acid, shikimic acid, protocatecuic acid 등이 존재하였다. 에스테르형 페놀산 화합물에는 tyrosol, t-cinnamic acid, ferulic acid, esculetin, caffeic acid, pcoumaric acid, hydroxytyrosol 등이 함유되었다. 결합형 페놀성 화합물에는 tyrosol, t-cinnamic, p-coumaric acid와 미확인 페놀성 물질들이 존재하였다. 따라서 광나무 잎은 xanthine oxidase 활성저해, LDL 산화, 혈소판 응집저해, 항균활성 등 다양한 생리활성을 나타내는 것으로 보고되고 있는 tyrosol, hydroxytyrosol, protocatecuic acid 등 풍부한 페놀성 화합물을 함유하고 있으므로 유용한 식물자원이 될 수 있음을 확인하였다. This study was designed to investigate the possible utilization of Ligustrum japonicum leaves as a source of functional ingredients. Contents of total phenolic compounds and condensed tannin were 0.89∼1.53% and 0.10∼0.13%, respectively. The major flavonoid compounds in the leaves of L. japonicum were luteolin, apigenin and their glycosides. Tyrosol, t-cinnamic acid, p-hydroxybenzoic acid, vanillic acid, shikimic acid and protocatecuic acid were detected in free phenolic acid, while tyrosol, t-cinnamic acid, ferulic acid, esculetin, caffeic acid, p-coumaric acid and hydroxytyrosol were detected in esterified phenolic acid. The insoluble phenolic acid contained tyrosol, t-cinnamic and p-caoumaric acid.

The problem of determining the 3-demensional motion of any two rough bodies after a collision involves some rather long analysis and yet in some points it differs essentially from the corresponding problem in tdwo dimensions. We consider a special problem where two rough ellipsolids moving in any manner collide, and analyze the three dimensional impact process with Coulomb friction and Poisson's hypothesis. The differential equations that describe that process of the impact induce a flow in the tangent velocity space, the flow patterns characterize the possible impact cases. By using the graphic method in impulse space and numerical integration thchnique, we analyzed the impact process inall the possible cases and presented the algorithm for determining the post-impact motion. The principles could be applied to the general problem in three dimensions. We verified the effectiveness of the analysis results by simulating the numerous significant examples.

최근 신재생에너지, 녹색성장분야의 연구는 미래 산업의 핵심 기술로 평가되고 있다. 특히나 태양전지 분야는 미래 대체 에너지 기술로써 크게 각광 받고 있으며 과거 실리콘 기반의 전력 생산용 태양전기 기술이 주가 되었지만 근래에는 모바일 기기의 보조 전력, 스마트 윈도우 등 다양한 산업에 적용 가능한 박막 태양전지 기술이 급속도로 발전을 하고 있다. 현재 박막 태양전지 기술은 아직까지도 산업화 기술에 근접하지 못하고 있지만 향후 5년이내에는 다양한 형태로 산업화가 이루어 질 것으로 예측하고 있다. 따라서 본 논문에서는 박막형 태양전지 중의 하나인 OPV태양전지의 산업화 적용을 위해 스프레이 공정 기술과 이를 이용하여 OPV 소자를 제작한 내용에 대해 기술했다.
