직장 내 여가경험이 직무태도와 조직시민행동에 미치는 영향
이호건(Lee, Ho-Keon),전병준(Chun, Byung-June) 한국산학기술학회 2011 한국산학기술학회논문지 Vol.12 No.3
최근 많은 기업들이 즐겁게 일할 수 있는 조직분위기를 조성하여 조직성과를 극대화하기 위하여 ‘Fun경영’ 에 관심을 기울이고 있다. 특히, 업무활동과 관계없는 여가활동을 지원하고 활성화함으로써 조직분위기를 고취시키고 궁극적으로는 성과를 향상시키려고 한다. 본 연구는 국내 기업에서 실시하고 있는 직장 내 여가활동에 대해 참가자들 이 느끼는 여가 경험을 확인하고, 여가경험이 구성원 정서 및 직무태도, 조직시민행동에 미치는 영향에 대해서 살펴 보았다. 또한, 여가경험과 직무태도, 조직시민행동과의 관계에서 긍정정서의 매개 효과에 대해서 검증하였다. 연구결 과, 직장 내 여가경험은 조직구성원의 긍정정서에 유의미한 영향을 미치는 것으로 나타났다. 또한, 구성원의 긍정정서 는 직무만족, 조직몰입 및 조직시민행동에 긍정적인 영향을 미치는 것으로 나타났다. 긍정정서는 여가경험과 직무태 도 및 조직시민행동과의 관계를 완전 매개하는 것으로 확인되었다. 직장 내 여가경험에 대한 본 연구는 Fun경영 활 동 중 업무와 직접적인 관련이 없는 여가활동이 구성원의 정서관리에 효과적인 수단임을 확인한다. 연구결과는 Fun경 영 설계 시 여가활동 자체보다는 여가경험을 통한 긍정정서의 유발이 더 중요함을 시사한다. The purpose of this study was to examine the relationship between leisure experience and job-attitude and organizational citizenship behavior. And this study indicates how positive emotion affects the relationship between leisure experience and job-attitude and organizational citizenship behavior. The results from this study are as follows: First, leisure experience influenced significantly the positive emotion, the positive emotion was giving positive affection to job satisfaction, organizational commitment, and organizational citizenship behavior. Second, positive emotion mediated between leisure experience and job-attitude and organizational citizenship behavior. This study was giving us implications that positive emotion from leisure experience is more important than leisure activities themselves when we plan ‘fun management'.

이상한(Sang Han Lee),김진수(Chin Soo Kim),권귀영(Guy Young Kwon),이호건(Ho Keon Lee) 대한구강악안면외과학회 1988 대한구강악안면외과학회지 Vol.14 No.1
The calcifying odontogenic cyst is an extremely rare disease. Gorlin and his associates first described the disease in 1962, and now recognized as a distinct entity by the WHO. The COC is generally regarded as a cystic, benign lesion of odontogenic origin with an epithelial lining that resembles odontogenic epithelium. This is a case report of COC occurred in the right mandibular posterior body area. The patient 29-years-old female, was admitted to dept. of oral and maxillofac. surgery, chief complaint of painless firm swelling on Rt. mandibular posterior teeth area. So, we confirmed that the lesion was COC through biopsy result. The primary treatment should be accomplished by surgical enucleation.

마우스 악하선의 DMBA유도 발암시의 병리조직학적 변화
이호건,김진수 慶北大學校 齒科大學 1990 慶北齒大論文集 Vol.7 No.1
The purpose of this study was to investigate carcinogenic effect of DMBA on the mouse submandibular glands. Seventy female mice were used in this study. They were divided into 14 experimental groups of 42 animals and 14 control groups of 28 animals. The submandibular glands of each experimental animals were incised and implanted with pure DMBA pellet(about 1.25mg). In contrast ot these, animals of control group were only incised on the submandibular glands without implantation of DMBA. 3 animals out experimental groups and 2 out of control one were sacrificed at 1, 3, 5th day and 1, 2, 3, 5, 8, 11, 12, 13, 14, 15, 16th weeks after application of carcinogen. The specimens were taken from their submandibular glands immediately after sacrifice and were routinely processed for light microscopic observations. The results obtained from this study were as follows. ; 1. According to gross observations, visible and palpable lesions developed nearly all mices of experimental groups 11 weeks after experiment in the right submaxillary gland area implanted with DMBA pellet. In control animals, no significant change was noticeable except inflammatory changes at early stage. 2. The histopathological alterations of the mouse submandibular glands induced by DMBA revealed changes according to time. a. The mouse submandibular glands showed necrosis, inflammatory infiltration, atrophy of acinic cell and ductal hyperplasia of granular convoluted tubule cells at 1 to 2 weeks after experiment. b. They showed severe ductal hyperplasia, ductal squamous metaplasia, epidermoid cyst and basal cell plemorphism at 5 to 8 weeks after experiment. c. They showed obvious squamous cell carcinoma after 8 weeks of experiment. d. From 11 to 16 weeks, persistent squamous cell carcinoma development, invasion into the adjacent connective tissue, and multiple tumor islands were observed. e. At 13 weeks, sarcomatous-like squamous cell carcinoma was also observed in one experimental animal. 3. The sequence of hstopathologic changes of experimental carcinogenesis in this study was initial inflammation, acinic cell atrophy accompanied by necrosis of connective tissues, proliferation of ductal epithelium squamous metaplasia and occurrence of squamous cell carcinoma. 4. The malignant tumors induced in this study were mainly squamous cell carcinomas. 5. Squamous cell carcinoma was thought to be originated from the lining epithelial cells of the large excretory duct.
