임진혁(Im, Jin-Hyuk),권혁(Kwon, Hyuk) 한국경영교육학회 2021 경영교육연구 Vol.36 No.6

[연구목적] 본 연구에서는 긍정심리자본이 창업의지에 어떠한 영향을 미치는지 분석함으로써 창업의지에 영향을 미치는 변수에 대한 이해를 폭을 넓히고자 하였다. 더불어 기업가정신은 창업의지에 강한 영향을 미치지만 기업가정신은 무엇으로부터 영향을 받는지에 대한 연구가 부족한 상황에서 본 연구를 통해 기업가정신에 영향을 미치는 요인을 발견하고자 하였다. [연구방법] 3개 대학의 대학생 322명을 대상으로 자기기입식 설문조사를 실시한 후 SPSS를 이용해 다중회귀분석과 Process Macro를 활용한 매개효과 분석을 실시하였다. [연구결과] 긍정심리자본은 창업의지에 긍정적인 영향을 미쳤지만 긍정심리자본 요인 중 회복탄력성의 유의성만이 검증되었다. 한편 긍정심리자본의 회복탄력성, 희망, 낙관은 기업가정신에 유의미한 영향을 미쳤으며 긍정심리자본(회복탄력성, 희망, 낙관)과 창업의지와의 관계에서 기업가정신은 완전매개효과를 보이는 것으로 나타났다. [연구의 시사점] 본 연구는 계획행동이론의 개념을 긍정심리자본과 창업의지로까지 확장했다는데 학술적 시사점이 있다. 또한 그간 창업의지에 영향을 미치는 요인에 대해 기법과 기술 중심의 창업교육과 지원제도가 다수를 이뤘지만 본 연구에서는 역량론에 기반하여 인지적 특성이라고 할 수 있는 긍정심리자본이 창업의지에 영향을 미친다는 결론을 통해 창업의지에 영향을 미치는 요인에 대한 이해의 폭을 확장하는데 기여하였다. [Purpose] This study tried to broaden our understanding of variables that affect entrepreneurial intentions by analyzing how positive psychological capital affects entrepreneurial intentions. In addition, in a situation where there is a lack of research on what influences entrepreneurship, this study tried to discover factors affecting entrepreneurship. [Methodology] After conducting a self-report questionnaire on 322 college students from three universities, SPSS was used to analyze mediating effects using multiple regression analysis and Process Macro. [Findings] It was confirmed that only resilience among positive psychological capital had a positive effect on the entrepreneurial intentions. In addition, resilience, hope, and optimism had a significant effect on entrepreneurship, and entrepreneurship was found to have a complete mediating effect in the relationship between positive psychological capital and entrepreneurial intentions. [Implications] This study has academic implications for expanding the concept of planning behavior theory to positive psychological capital and entrepreneurial intentions. In addition, this study contributed to expanding the understanding of the factors influencing entrepreneurial intention by concluding that positive psychological capital, which can be called a cognitive characteristic, affects the entrepreneurial intentions based on the competency theory.

This study focused on the characteristic analysis on the driving landscape of Pakdaljaegil. Especially, the study has a concern about the relation between the visual preference and dynamic vision amount change rate. As a type of sequence landscape, the driving landscape can be defined as a continuous and accumulated memory by car driving. By reviewing former related researches, the study had established the frame work for analyzing the driving landscape of Pakdaljaegil. The basic methods the study suggested are using animation and the concept of dynamic vision amount change rate. Then, by using the real movie animation the study could collect the preference rate for every 10 second time frame. And by using Mesh analysis, the vision amount and its change rate were calculated for each time frame. With the SPSS analysis tool, the study had a result of the relation only between the preference and vision amount of distance views. However, the study could get a result of the characteristics of driving landscape of Pakdaljaegil. It could be characterized as a surrounded landscape type by trees near by the road. and also, the study could carefully suggest the possibilities the relationship between the preference and other elements of dynamic vision amount change rate.

AbstractThe purpose of this work was to study the compatibility of several commercially available dentin adhesives with composite resins. In this study, V-shaped cavity preparations were created on both buccal and lingual surfaces of 60 extracted human premolars(3mmX3mmX 2mm deep). Preparations were located such that the occlusal margins were on the enamel and the gingival margins were on the cementum(lmm below the CEJ). These specimens were randomly divided into three equal groups. Three dentin adhesives(Scotchbond Multi- purpose, All Bond 2, Prisma Universal Bond 3) were applied to the cavity in accordance with each manufacturer's instructions. The teeth in each group were restored with four composite resins (Silux plus, Z100, Bisfil, Prisma TPH)in three increments, with each incre- ment light-cured for 40 seconds. All specimens were exposed to 500 cycles of thermal stress. Specimens then placed in a silver ni<rate solution(50% by weight) and stored in darkness for 24 hours. They were then immersed for 6 hours in photographic developing solution under flourescent light. Specimens were sectioned buccolingually through the center of the restoration and observed under a binocular stereoscope. To compare the marginal leakage, ANOVA and Dunkan's multiple range tests were used in analysis. Selected samples were further studied using scanning electron microscopy(XL20, Philips, The Netherlands).The results were as follows. 1. In all groups, the enamel margin showed significantly less leakage than the cementum margin. 2. No statistically significant differences were found in microleakage when composite resins were used with their proprietary dentin adhesives. 3. In comparison between dentin adhesives, Prisma Universal Bond 3 showed significantly less leakage at the enamel margin and Scotchbond multi-purpose showed significantly less leakage at the cementum margin than -the other groups. 4. In comparison between composite resins, Silux Plus showed significantly more leakage than other groups at the enamel margin and no statistically significant differences were found in microleakage at the cementum margin. 5. According to the backscattered scanning electron microscope, microleakage occurred via gaps at the dentin adhesives/dentin interface

The purpose of this study was to confirm the analysis method and also to estimate the pharmacokinetic parameters of tacrolimus in human volunteers. The pharmacokinetics of tacrolimus tablet was examined on 24 healthy volunteers who received a single oral dose(4mg) of each preparation in the fasting state. After an oral dosing, blood samples were collected for a period of 72 hours. Blood concentrations of tacrolimus were determined using a liquid chromatographic electrospray mass spectrometric (LC-MS) method. The pharmacokinetic parameters were calculated with non-compartmental(AUC, C_(max), T_(max), Cl_(t), V/F) and compartmental(K_(el), K_(a), K_(12), K_(21), t_(1/2)) pharmacokinetic analysis using WinNonlin program. The estimated means of AUC_(0-72hours), C_(max) and T_(max) were 425.54 ± 197.49 ng·hr/ml, 76.14 ± 29.18 ng/ml and 1.40 ± 0.44 hr, respectively. The means of other pharmacokinetic parameters(V/F, CL_(t), K_(el), K_(a), K_(23), K_(32) and t_(1/2)) were 35.12 ± 34.28 L, 10.45 ± 5.32 L/hr, 0.39 ± 0.21 hr^(-1), 1.91 ± 4.17 hr^(-1), 0.32 ± 0.33 hr^(-1), 0.07 ± 0.09 hr^(-1), 26.94 ± 10.19 hr^(-1), respectively.

In this paper, we propose a bidirectional mobile Ad Hoc routing protocol based on AODV(ad-hoc on-demand distance vector routing) with QoS(quality of service) support. At presence, wireless mobile communication focuses on how to efficiently support mobility of users more than QoS guarantee. However, in order to satisfy requirement of various applications which have been or will be served, QoS guarantee between end points is a very important issue. The existing AODV routing protocol is implemented to use only BE (Best Effort) service. However, actual wireless mobile environment requires to reduce a waste of communication resources and meet with the real-time change of data paths by setting up routes with QoS support, considering available communication resources at each node in advance. Therefore, in this thesis, we propose an adaptive QoS support method using hello message in order to rapidly meet with the change of available communication resources and to smoothly perform route maintenance. For performance evaluation, we analyzed the average data reception rate. At that time, we used evaluation parameters such as node's mobility-stop time, hello message period, and packet priority, considering the node's mobility and the number of best effort/QoS data flows. As results, we found that with our proposed method the average data reception rate was increased 16.293%, 15.914%, 17.238% for 300 mobility-stop second case and 4.809%, 4.264%, 2.956% for 300 mobility-stop second case.

Thirteen-year-old girl complaining of the swelling and pain on the left midface visited our dental hospital. On the radiogaphic examination, well-defined radiolucent lesion with hyperostotic border was found in the left maxilla accompanying with the external root resorption of the involved teeth and the displaced second molar. CT showed calcified bodies, thinning of hard palate, inferior orbital wall and lateral wall of nasal fossa, and thinning and perforation of the buccal plate of the maxilla. Enucleation and curettage of the lesion and nasoantrostomy was carried out and histopathologic examination mainly showed a solid tumor tissue composed of odontogenic epithelium and pulp tissues admixed with dentin and enamel formation. And some part of reduced follicular epithelium of tooth germ showed a change mimicking calcifying odontogenic cyst, Taken together, we concluded the lesion is an ameloblastic fibro-odontoma with a change of calcifying odontogenic cyst.

이혁진 서울保健大學 1996 論文集 Vol.16 No.1

The purpose of this study is to classify types of Tourism Areas' in terms of the time-distance method. For this, the types of tourism area are set up by the 'Stay Period'. Literature review and questionnaire method have been used for the purpose. Respondents are centered on Seoul metropolitan area, capital circle. The major findings of this study are summarized as follows; First, As for the recognition about tourism area, the male respondents showed higher degree of recognition than the female ones. Younger respondents with higher educational background also displayed higher recognition. Second, As for the preference on tourism area, Ch'ungbu area is the most preferred one, and it is followed by Tongnam, Ch'ungch'oˇng, Seonam, and Cheju area. The stay period in each area is that Ch'ungbu is 1 day, Ch'ungch'oˇng is 1 night 2 days, Seonam is 2 nights 3 days and Tongnam and Cheju are 3 nights 4 days. Third, as far as 'Administrative Unit' concerns, the favorite district is Kyoˇnggi-do. Next is Kangwon, Kyoˇngbuk, Kyoˇngnam, Ch'ungnam, Choˇnnam, Cheju, Ch'ungbuk and Choˇnbuk. In regard to distribution by the stay period in them, 1 day's trip is preferred in Kyoˇnggi-do, 1 night 2 days' trip in Kangwon-do and Ch'ungchoˇngnambuk-do, 2 nights 3 days' trip in Kangwon-do and Kyoˇngsangnambuk-do and 3 nights 4 days' trip in Kyoˇngsangnambuk-do and Cheju-do. Fourth, tourism area types can be divided into 4 patterns on the basis of the stay period;'1 Day', '1 night', '2 nights' and '3 nights'. 1. '1 day' is composed of Seoul-neighborhood zone, Inch'oˇn-Coastal zone, and Ch'unchoˇn zone in Ch'ungbu area. 2. '1 night' is composed of Ch'ungch ng area and a part of Ch'ungbu area. 3. '2 nights' is composed of Tongnam and Seonam area. 4. '3 nights' is composed of South-coastal zone and Cheju area including many islands. Based on the results, the following suggestions can be made for future study. One is the necessity of classifying the tourism areas around other Kwangyeok cities like Pusan, Taegu, Kwangju and Taejon. The other is that it is needed to classify these types by traffic modes and socio-demographic characteristics.
