목적: 닭의 굴곡 건 파열의 봉합 시에 단순 봉합한 군과 양막을 이식한 봉합군, 방사선 처리된 양막을 이식한 봉합군을 비교 분석하여 각각이 조직 유착에 미치는 영향에 대해 알아보고자 하였다. 대상 및 방법: 아홉 마리의 닭을 대상으로 하여 양측하지의 제2 굴곡 건을 절반 절단한 후 단순 봉합한 것을 A군, 봉합 후 단순 처리된 양막을 이식한 것을 B군, 동결 건조 및 25 kGy 방사선 처리된 양막을 이식한 것을 C군으로 하였다. 수술 후 3주, 6주, 9주에 각 군마다 1마리씩 희생시켜 조직 유착 정도를 육안으로 관찰하였고 조직학적 검사를 시행해 일반적인 조직학적 변화와 염증세포의 침윤정도, 섬유화 등을 비교 관찰하였다. 결과: 모든 시기에 A군과 B군에 비해 C군에서 염증세포 침윤과 섬유화가 낮았다. 결론: 닭의 굴곡 건 파열의 봉합 시에 방사선 처리된 양막 이식이 염증 및 조직 유착 감소에 효과적으로 사료된다. Purpose: The role of the amniotic membrane with or without radiation was investigated with regard to preventing adhesion after flexor tenorrhaphy of chicken. Materials and Methods: Nine chicken were divided into three groups. The second flexor tendon of the chicken was operated on. In group A, the flexor tendon was excised and one half and the tendon was repaired. In group B, the repaired tendon was covered with an amniotic membrane. In group C, the repaired tendon was covered with a lyophilised and 25 k㏉ irradiated amniotic membrane. The gross and histology findings on the level of inflammation and fibrosis of the repaired tendon were evaluated at 3, 6 and 9 weeks after surgery. Results: Group C had the least inflammatory cell infiltration and fibroblast proliferation at any time. Conclusion: The use of radiated amniotic membrane was effective in preventing inflammation and adhesion after flexor tenorrhaphy in chickens.

뇌하수체 농양은 매우 드물지만 터키안 기저부의 골수막염에 의한 직접 전파에 의해 발생가능하다. 저자들은 편도주위와 후두인두염으로 치료 중 뇌기저부의 골수염이 동반되었으나 간과하고 항생제를 조기 중단 후 악화되는 두통으로 내원한 환자에서 뇌 MRI와 혈액배양으로 K. pneumoniae에 의한 뇌하수체 농양을 진단하고 수술적 치료없이 항생제 치료만으로 호전된 1예를 경험하여 문헌고찰과 함께 보고하는 바이다. Pituitary abscesses are rare, but potentially life-threatening. Drainage of the abscess through a transsphenoidal approach is the standard treatment for a pituitary abscess. Recently, we experienced a patient with a Klebsiella pneumoniae pituitary abscess who was cured using antibiotics, without surgery. A 52-year-old man had a chronic, persistent headache for 1 month. Magnetic resonance imaging showed a fluid collection in his pituitary fossa. Pituitary hormone tests showed mild hypopituitarism. He was put on antibiotics and discharged after 6 weeks without sequelae. An early diagnosis and adequate antibiotics treatment for this life-threatening infection can result in an excellent prognosis. (Korean J Med 77:133-138, 2009)

Although the outsourcing of information systems has been widely used for a long time, there are few systematical researches on the situational variables in the information system of restaurant management and outsourcing results. For this reason, this study examines the relationships among the situational variables in the information system of restaurant companies, the level of outsourcing, and outsourcing results and attempts to raise the quality of restaurant management and suggest progressive ways of rational operation and efficient management of employees. The results of the empirical analysis of this study are summarized as follows. First, the financial capability and information technology resources of a contracting company have statistically significant effects on partnership; the external circumstances of information systems such as the uncertainty of information technology and the uncertainty of circumstances have positive effects on the quality of partnership. Second, the reliability and interdependence of a contracting company, or the service company of a client company have positive effects on outsourcing results. Third, the financial capability of a contracting company has positive effects on outsourcing results while information technology resources and the capability of information technology have positive effects on efficiency at work. Furthermore, the uncertainty of information technology and the uncertainty of circumstances have positive effects on the external circumstances of information systems.

This study identified and explained the prototypes of belief systems about the kindergarten curriculum with the use of Stephenson`s Q-methodology. The sample consisted of 15 preschool teachers and 15 college students majoring in early childhood education. A Q-deck composed of 48 cards was developed by the researchers and sorted by the subjects. The obtained Q-sort scores were analyzed by factor analysis. The findings revealed that the subjects were divided into 3 types: the practical-disciplinary type consisting of mostly of teachers, the theoretical-openness type consisting mostly of students, and the compromising type consisting of some teachers and some students.

This study identified and explained the prototypes of teacher`s belief about children`s play with the use of Stephenson`s Q-methodology. The sample consisted of 35 kindergarten teachers. A Q-deck composed of 48 cards, derived in part from a review of related literature and was developed by the researchers and sorted by the subjects. The obtained Q-sort scores were analyzed by factor analysis. The findings revealed that the subjects were divided into 3 belief types : life-experienced, developmental-disciplinary, cultural-environmental. Likely explanations for these results are considered, and implications are discussed.
