The number of patients with coronary artery disease and peripheral vascular disease are increasing, and the need of small diameter vessel is also increasing. We developed small diameter artificial vessel and experimented in vivo. We got allogenic valve from mongrel dogs, and removed all cells from the allogenic valve. Then, we seeded autologous bone marrow cells onto the decellularized scaffold. After implantation of artificial vessel into the canine carotid artery, we performed angiography regularly. In case of vessel occlusion or at 8 weeks after operation, we euthanized dogs, and retrieved the implanted artificial vessels. Control vessels were all occluded except one (which developed aneurysmal dilatation). But autologous cell seeded vascular graft were patent by 4 weeks in one, by 6 in one and by 8 weeks in two. Histologic examination of patent vessel revealed similar structure to native artery. Tissue-engineered vascular graft manufactured with decellularized allogenic matrix and autologous bone marrow cells showed that tissue engineered graft had similar structure to native artery.

The importance of coaching leadership has been highlighted to enhance creativity and competence of human resources in convergence environment. This paper was validated through a structural relationships model, the impact of coaching leadership on behavioral dimensions of organizational effectiveness by focusing on mediating role of job characteristics. Coaching leadership activities showed a significant positive effect on job characteristics and turnover intentions. Job characteristics appear to have a mediating effect on the relationship between coaching leadership and organizational effectiveness, especially the coaching leadership itself not necessarily to improve organizational citizenship behavior, can increase organizational citizenship behavior when formed into a positive awareness of the job characteristics of organizational members.

This study explored a structural model that predicted the influencing factors of GRIT and job crafting on the organizational effectiveness of organizational commitment and job satisfaction of medical center employees and verified the relationship between them. This study was conducted on 450 subjects, including doctors, nurses, administrative staff, and technical health service staff working at a university-affiliated hospital, from June 1, 2020 to June 15, 2020, and collected data were analyzed using SPSS 26.0 and AMOS 26.0. The results of this study showed that the higher the GRIT, the more active the job crafting(β=.751, p<.001), which appeared to have a positive effect on organizational commitment (β=.297, p=.005) and job satisfaction(β=.353, p<.001). Although the GRIT of medical center employees did not show a direct effect on organizational commitment and job satisfaction, indicators of organizational effectiveness and employees' job crafting thoroughly played an intermediary role in the relationship between GRIT and organizational effectiveness. These results are expected to be utilized as useful information in developing measures for human resources management of medical center employees.

Globalization of economy has a significant impact on the organization of economic Space. This paper examines the concepts of globalization and localization, major trends of the changes in the organization of economic space in the Pacific rim, and the major processes of the changes. Intra-regional trade and foreign direct investments have increased considerably in the Pacific region with the progress of globalization during the last decade. Due to the Progress of globalization of economy in the Pacific rim, some growth triangles have extended their agglomeration area beyond the national boundaries and several new industrial districts have developed. The reorganization of the economic space in the Pacific rim has been resulted from industrial restructuring of NIEs, spatial division of labor along the commodity chains, and the formation of industrial networks within the region. The ‘cooperative network strategy’has been suggested to minimize the negative effects of glocalization and for the sustainable development in the Pacific rim.

This study analyze whether the organizational learning culture affects the firm's dynamic capacity and whether the dynamic capacity mediates the relationship between organizational learning culture and management performance. Respectively. First, "The more organizational structure is organic, the higher the integrated relocation capacity and learning capacity. Organizations with organic organizational structures were found to have the ability to successfully adapt to external changes because there is a practice that is not tied to formal processing or procedures. Second, it can be seen that there is a positive (+) influence on the relocation capacity among the dynamic competence of the learning culture of the corporate organization. Third, both sub-factors of dynamic competence have positive (+) influence on business performance. Also, there was no mediating effect of dynamic competence related to learning culture.

Seven hypotheses were verified using frequency analysis, correlation analysis, reliability analysis, confirmatory factor analysis, path analysis and structural equation modeling through SPSS and AMOS statistics. The results are as follows. First, internal marketing had a positive effect on customer orientation. Second, internal marketing had a positive effect on job satisfaction. Third, internal marketing had a positive effect on organizational trust. Fourth, organizational trust had a positive effect on customer orientation. Fifth, organizational trust had a positive effect on job satisfaction. Sixth, organizational trust was found to partially mediate relationship between internal marketing and customer orientation. Seventh, organizational trust was found to partially mediate relationship between internal marketing and job satisfaction.

신유선 감염에 저항하는 소 방어효과는 소의 전신적인 방어기전과 유두조직의 건강에 주요한 영향이 있는 유두내 국소적 방어작용에 의하여 결정된다. 착유기에 의하여 유발되는 유두조직 장애의 정확한 평가는 착유설비와 일상적인 착오와 같은 것이 소와 관계되는 특성의 몇가지 응용이 필요하다. 유두조직의 3가지는 차이가 있다. (i) 외견과 유두상태, (ii) 해부학적 구조와 조직구성 그리고 (iii) 생리적 활동상태. 유두반응의 그런 상태 모두의 특성이 기술되어 있고, 신감염의 잠재적 위험성이 관계된다. 유두조직 측정에 추가되는 것은 분만전 우유시료와 유두관 흡수시료의 조사로 기계유발 유두조직반응 분석을 위하여 대단히 도움이 된다. 안내지침은 신감염 위험이 있을 수 있는 기계유발 유두반응평가를 위하여 제안된다.

한국산 거머리 각배obdeffo linea약의 상피조직을 배부상피(dorsal epithelium), 복부 상피(ventral epithelium) 측부상피(lateral epithelium) 별로 3부위를 광학현미경과 전자현미경으로 관찰한 결과 다음과 같은 결론을 얻었다. 전자현미경 관찰에서 거머리 상피조직은 3부위 모두 불규칙한 세포로 구성되었으며, 그들은 전자밀도가 높은세포와 중등도인세포 그리고 투명한세포 등 3종류로 구분되었다. 거머리의 불규칙한 상피조직 사이에서 두 종류의 분비성 과립인 a 및 b형과립과 색소성 과립인 D형과립이 관찰되었다 배부상피조직에서 관찰된 a형과립(66$\times$83 Um)은 복부와 측부에서 관찰된 과립(33H66 Um) 보다 형태가 훨씬 크고 그 수 도 두배정도 많이 관찰된 반면, b형과립은 모든 상피조직에서 동일한 크기와 형태를 보였지만 그 수는 배부와 복부에 비해 측부상피조직에서 두배정도 많이 관찰되었다 이상 분비성 과립들은 PAS-alcian blue(pH 2.5) 반응에서 모두 PAS에 강한 양성반응을 나타내어 중성점액다당류로 확인되었다. 거머리 몸마디를 이루는 체절은 배부와 복부에서 그 주름의 깊이와 넓이가 각각 다르게 나타나서(배부, 40 Um와 330 urn, 복부 100 urn와 150 urn), 복부의 깊은 체절이 발(foot)의 역활을 수행 하였다.

1년에도 수십 수백 개씩 스타트업이 생겨나고 있다. 아마도 모두 미래의 구글과 페이스북, 그리고 아마존이 되길 희망하며 하루하루 가열차게 달리고 있다. 하지만 그 많은 스타트업 중 소위 성공했다 불릴 수 있는 기업은 손에 꼽는다. 능력 있는 창업가, 기발한 사업 모델과 아이디어 그리고 이를 뒷받침해 줄 기술력과 자본이 있다고 성공할 수 없다. 스타트업 기업을 굴러가게 하는 힘은 결국 그 조직의 구성원에게서 나오기에 성공한 스타트업에겐 모두 그들 만의 '조직문화'가 있다. 그게 모두에게 좋은 문화일 필요는 없을 것이다. 그 조직에 가장 접합한, 그래서 구성원의 구성원의 공감대를 사 '일하고 싶은 회사'가 될 수 있게 하는 '조직 문화'가 있는 스타트업이 수많은 인재를 모아 성장을 거듭해 올 수 있었고 그것이 결국 스타트업을 성공으로 이끌었던 것이다. 이런 조직 문화는 회사 초창기에 세팅할수록 해당 기업의 성공 확률도 높아진다. 7년 미만의 초기 스타트업 기업을 대상으로 조직문화 유형이 스타트업 구성원의 조직 몰입과 조직성과에 어떠한 영향을 주는지에 대한 실증분석을 목적으로 하였다. 초기 스타트업 기업의 조직문화 차원은 경쟁가치모형의 혁신문화와 위계문화로 구분하였으며, 조직성과는 스타트업의 서비스, 제품을 경험한 이용자들의 서비스 만족도를 활용하였다. 조직문화는 외부환경에 대한 적응과 조직내부 통합의 문제를 해결하기 위하여 구성원들에 의해 창조 발전되어 학습되는 기본가정으로서 스타트업 구성원들에 의해 공유된 가치(values), 신념(beliefs), 규범(norms)의 체계로 정의한다. 따라서 어떠한 조직문화를 갖는냐에 따라 조직 구성원의 몰입, 충성심, 직무동기, 직무성과는 물론 조직성과와 혁신을 포함하는 여러 조직 요인도 직 갑적인 영향을 받는다. 7년 미만의 초기 스타트업 혁신문화가 스타트업 구성원의 조직몰입에 긍정적인 영향을 미치며, 조직몰입이 스타트업 서비스, 제품을 경험한 이용자들의 서비스 만족도에도 긍정적인 효과가 있는 것으로 나타났다.

We describe tubular structures on the cuticle of two representatives of the genus Gordius by scanning electron microscopy. One female from Korea could not be identified further while a male from New Zealand belonged to Gordius paranensis. Other male specimens of G. paranensis did not show tubular structures or the corresponding pores on the cuticle. Therefore it is assumed that tubular structures are not species-specific structures, but also no artifacts or contaminations. They might be glandular products, but this has to be verified by further documentations and investigation of the inner structure of it.
