창업에 대한 관심이 높아지면서, 대학에서 더욱 많고 다양한 창업교육 프로그램이 실시되고 있다. 효과적인 대학의 창업 프로그램을 위해 경영자 정신과 자질에 대한 개념정립이 요구되고 있다. 하지만 아직 기업과 정신과 관련된 개인 특성에 관한 연구들은 개인특성과 실제적인 창업활동과의 인과적 관계에 대한 명확한 결론을 제시하지 못하고 있다. 본 연구는 개인특성연구에서 상황요인의 포함이 모델의 예측력을 높인다는 이론적 흐름에 기반하여 개인적 특성이 창업태도와 실행의도에 영향을 줄 때, 이 영향을 주변인들의 지지(사회적지지)가 중요한 조절역할을 한다고 가정하고 연구를 진행하였다. 또한 기술창업을 주로 하여 창업과정에서 어려움이 큰 이공계 대학원생을 대상으로 연구하였다. 연구결과, 창업태도는 창업의도에 유의한 영향을 주었고, 개인적 특성인 기업가성향 중 혁신성과 창업효능감은 창업태도를 높이고, 창업의도를 높이는 데 유의한 영향이 있었다. 또한 사회적 지지는 기업가 성향 및 창업효능감의 모든 변수가 창업태도에 미치는 영향을 증폭하는 유의한 조절효과를 보여주었다. 또한 사회적 지지를 고려하지 않은 경우 기업가 성향 중 위험감수성과 진취성은 창업태도에 유의한 영향을 주지 않았으나, 사회적 지지가 고려된 모델에서는 혁신성, 위험감수성, 진취성, 창업효능감 모두 창업태도에 유의한 영향을 주었다. 따라서 본 연구를 통해 개인적 특성 모델은 창업의도에 유의한 영향을 주며, 이때 사회적 지지는 중요한 조절효과를 갖는 요인이고, 상황요인을 모델에 포함한다면 신뢰성이 높아진다는 점을 확인할 수 있었다. This study is based on the theoretical trend that explanatory power can be enhanced when the interaction effect of situational factors is included in the model in the study of personal traits. Therefore, it was assumed that when personal traits influence entrepreneurial attitude and intention, the support of surrounding people(social support) plays an important moderating role. As a result of the study, entrepreneurial attitude had a significant effect on entrepreneurial intention, and innovation and self-efficacy had a significant effect on entrepreneurial attitude and intention. In addition, social support showed a significant moderating effect of amplifying the influence of all variables of entrepeneur propensity and self-efficacy on entrepreneurial attitude. In addition, when social support was not considered in the model, risk-taking propensity and proactiveness did not have a significant effect on entrepreneurial attitude, but in a model that considered social support, innovativeness, risk-taking propensity, proactiveness, and self-efficacy were all significant effect on entrepreneurial attitude. Therefore, it was confirmed that the personal trait model has a significant influence on the entrepreneurial intention, and in this model, social support is a factor that has an important moderating effect, and if the situational factors are included in the model, reliability increases.

Background: In practicing qigong, people must achieve three points : adjust their posture, control their breathing, and have a peace of mind. That is, Cho-Sin [調身], Cho-Sik [調息], Cho-Sim [調心]. Slow respiration is the important pattern of respiration to improve the human health. However, unsuitable breathing training have been occurred to mental disorder such as insomnia, anorexia etc. So, we think that the breathing training to consider the individual variations are desired. Objectives: We performed this study to examine the physiological effects of controlled respiration on the normal range of frequency domain electroencephalogram(EEG) in healthy subjects. Also, to study examine individual variations according to the physiological effects between controlled respiration and Han-Yeol [寒熱], respiration period, gender and age-related groups on the EEG in healthy subjects. Methods: When the subjects controlled the time of breathing (inspiration and expiration time) consciously, compared with natural respiration, and that their physiological phenomena are measured by EEG. In this research we used breathing time as in a qigong training (The Six-Word Excise) and observed physiological phenomena of the controlled natural respiration period with the ratio of seven to three(longer inspiration) and three to seven(longer expiration). We determined, heat-cold score by Han-Yeol [寒熱] questionnaire, average of natural respiration period, according to decade, EEG of 140 healthy subjects (14 to 68 years old; 38 males, 102 females) by means of alpha, beta spectral relative power. Results: 1) In Controlled respiration compared with the natural respiration, a I (Fp2) and β I (Fp1, Fp2, F3, F4) decreased on the EEG. 2) In controlled respiration compared with the natural respiration, β I (Fp1, Fp2, F3, F4) increased with cold group, a/β (F3) decreased with heat group, a I (Fp2)increased with cold group in longer inspiration. But by means of compound effects, a Ⅱ (F3) increased with cold group in longer inspiration, the other side a I (F3) decreased with heat group in controlled respiration on the EEG. 3) In controlled respiration compared with the natural respiration, a I (Fp2) decreased with decreased-respiratory-rate(D.R.R.) group, β I (Fp1, Fp2, F3, F4) increased with LR.R. and D.R.R. groups, a/β (F3) decreased with D.R.R. group. But by means of compound effects, in controlled respiration compared with the natural respiration, a/β (F3) decreased with D.R.R. group on the EEG. 4) In controlled respiration compared with the natural respiration, β I (Fp1, F3, F4) increased with female group, β I (Fp2) increased with male and female groups, a I β (F3) decreased with male group. But by means of compound effects, in controlled respiration compared with the natural respiration, a I (Fp2) increased with female group on the EEG. 5) Compared with the natural respiration, in longer expiration a I (Fp2) increased in their forties group, in longer inspiration a I (Fp2) increased in their fifties group. But by means of compound effects, in controlled respiration compared with the natural respiration, β I (Fp1) decreased in teens group on the EEG. Conclusions : This study has declined natural respiration of individuals and discovered that there were significant individual variations by means of the physiological effects between controlled respiration and Han-Yeol [寒熱], respiration period, gender and age-related groups on the EEG.

In the 21 century the number of participants in folk culture tourism has increased significantly and its popularity has grown rapidly. Folk culture tourism does not only represent history but encompasses all aspects of human history. World folk culture comprises on one part the tangible heritage, that which is unmovable, such as monuments, buildings, archaeological sites, and historic complexes which embody cultural significant traditions. World folk culture also includes the intangible movable heritage such as intellectual heritage, including artworks of archaeological importance and those representing skills. However, to obtain a tourist product value, intangible heritage needs to be transformed into a tangible one, through their own symbol and meaning, so that it can reflect its own unique cultural character. In particular the world folk culture is one of the most important tourism resources. The purpose of this research is to verify what factors change a folk culture into a tourism product and, how to create tourist products through world folk culture items in a way that contributes to the Korean tourism industry. To develop this theory of tourism merchandising, world folk culture has been analyzed strategic approach. The development into a world folk culture tourism product has following process: First, recognition and understanding of the meaning and value of the world folk culture items. Second, value creation as a tourist product through cultural resources. Third, creation of traditional cultural image, uniqueness and theme on tangible and intangible resources, Finally, application of Korean traditional concept to the tourist facilities.

Purpose: Diabetes mellitus refers to one of several risk factors for cardiovascular diseases, renal failure and so on. Medical treatments of T2DM cannot suggest a perfect cure. But gastric bypass resulting in the exclusion of the duodenum and proximal jejunum has been shown to improve or resolve T2DM. The goal of this study is to evaluate the effect of duodenojejunal bypass for T2DM patients below BMI 25 ㎏/㎡ in early postoperative period. Methods: Duodenojejunal bypass was performed on 25 patients at Inha University Hospital from July 2009 to April 2010. We compared 75 g OGTT, insulin, C peptide to those 7 days postoperative. The definitions for improvement are serum glucose level below 200 ㎎/㎗ of 75 g OGTT at 120 min or below 200 ㎎/㎗ at every other time in spite of over 200 ㎎/㎗ at 120 min. Results: A total of 25 patients (15 men and 10 women) were included. Median value BMI was 23.17 ㎏/㎡ and the mean duration of T2DM was 8.3 years. There was a significant decrease of postoperative 75 g OGTT levels from 176, 268, 345, 373, 371 ㎎/㎗ to 125, 170, 200, 225 and 241 ㎎/㎗, respectively (P<0.001). Only patients’ age was an independent factor resolution of T2DM based on this study. Conclusion: Duodenojejunal bypass could be one viable treatment modality for improving or resolving of T2DM although these are early results. This study has preliminary meanings only and the results of longer follow-up and a larger number of patients are necessary, by which we should be able to determine the effect and indications for surgical treatment of T2DM.
