This study have two purposes. The first is to examine the relationship between organizational socialization (i.e., level of skills, relationships with members, understanding of organization`s goals and values) and organizational Commitment . The second is to examine the moderating effect of the person-organization fit on the relationship between organizational socialization and organizational Commitment. As results of the analysis, the three organizational socialization; level of skills, relationships with members, understanding of organization`s goals and values have a positive effect on organizational commitment. Second, regarding the moderating effect of person-organization fit on the organizational socialization and organizational Commitment, person-organization fit have shown a partial moderating effect. So, organizations need to consider the effects of their socialization practices on newcomers` ability to engage in proactive behaviors. If organizations want newcomers to play an active role in their own socialization and to facilitate their own adjustment, then they need to provide newcomers with social and interpersonal opportunities to interact and communicate with other members of the organization. They might also consider training newcomers to be proactive.

출생 전후의 생쥐 뇌의 발생과정에서 열충격단백질70 mRNA 발현 세포의 분포 양상에 대하여 riboprobe를 이용한 하이 브리드조직화학기법 (in situ hybridization technique)을 적용하여 형태학적 연구를 시행하였다. 열충격단백질70 mRNA 양성세포가 특이적으로 관찰된 표본을 분석하여 다음과 같은 결과를 얻었다. 1. 발생 16일군에서는 열충격단백질70 mRNA 양성 반응이 척수에서 강하게, 넷째뇌실 주위의 뇌실막세포와 소뇌 등에서 는 중등도로, 대뇌겉질, 후각망울과 사이뇌와 같은 상위 중추의 세포에서는 약하게 관찰되었다. 2. 발생 18일군에서는 열충격단백질70 mRNA 양성 반응이 16일군에서보다 상위에 위치한 사이뇌 등의 중추신경계통에서도 중등도로 발현되었지만 대뇌겉질에서는 여전히 약하게 발현되었다. 3. 출생 0일군에서는 열충격단백질70 mRNA 양성 반응이 중추신경계통의 전반에 걸쳐 중등도로 또는 강하게 발현되었으며 특히 대뇌겉질에서 겉질판의 과립모양세포위층과 밑판, 해마 등에서 뚜렷한 중등도의 양성 반응이 관찰되었다. 4. 출생 2일군에서는 출생 0일군에서와 유사하였으며 대뇌겉질과 소뇌의 분화가 더욱 진행된 양상을 나타내었다. 5. 열충격단백질70 mRNA는 세포분열이 활발한 부위나 분화과정이 진행중인 부위의 세포에서 강하게 발현되었으며 발생과정이 진행됨에 따라 하위의 중추신경계통으로부터 상위의 중추신경계통으로 발현 범위가 확대되는 양상을 보였다. 이상의 결과로 미루어볼 때 열충격단백질70은 중추신경계통의 발생 및 분화에 있어서 중요한 역할을 수행할 것으로 생각된다. Using in situ hybridization technique with digoxigenin-labelled riboprobe, study on the expression of hsp 70 mRNA in the developing mouse brain was performed. The results obtained are as follows; 1. In embryonic day 16 group, cells with strong reactivity to hsp70 mRNA were found in spinal cord. In neuroepithelial layer lining fourth ventricle and external granular layer of cerebellum, moderate reactivity was observed. But the reactivity was weak in the forebrain including cerebral cortex, diencephalon and olfactory bulb. 2. In embryonic day 18 group, the regional pattern of hsp70 mRNA expression was similar to that of embryonic day 16 group. In medulla oblongata, however, stronger reactivity was found in the embryonic day 18 group. 3. In postnatal day 0 mice group, cells with moderate or strong reactivity to hsp70 mRNA were found in the overall area of central nervous system, Especially, cells with moderate reactivity were found in the dentate gyrus of hippocampus, and the supragranular cortical plate and subplate neocortex. 4. In postnatal day 2 mice group, cells with moderate or strong reactivity to hsp70 mRNA were found in the same pattern as in postnatal day 0 group. Further differentiation of cerebral cortex and cerebellum was found. 5. Strong expression of hsp70 mRNA was found in the areas with high rate of cell division. In general, the area of expression moved to more rostral area in central nervous system as development proceeds. Above results suggest that hsp70 play an important role in the development and differentiation of central nervous system.

Since the introduction of the concept of osseointegration, the success rate of dental implant has increased dramatically. So, the uses of dental implant in the treatment of partially or fully edentulous patients have played an important role in dental rehabilitation. Regardless of high success rate of dental implant, some amounts of fixtures cannot help failing. We can classify dental implant failure according to timing, causative factor, etc. This study is focused on dental implant fixture failure, occurring during preprosthetic stage. There are various reasons that cause implant failure on this periods, such as improper patient selection, poor bone quality, and periimplantitis, etc. We investigate the survival rate of 1058 fixtures, which installed in 306 patients in our clinic from January 1997 to December 1999, according to type, sex, location, fixture length and width, using Kaplan-Meier product-limit method and to compare each other with log-rank test. Overall survival rate was 96.80%, and 33 implants failed over the preprosthetic stage. Our survey data identified posterior location of mandible as being associated with implant failure(P<0.05).

미숙아에서 유문협착증은 매우 드문 질환으로 증상이 비전형적이고 한번의 복부 초음파 검사로 진단이 어렵다. 저자들은 구토와 수유 곤란이 발생한 미숙아에서 계속적인 복부 초음파 검사와 위장관 조영술로 유문협착증으로 진단하였고 수술 후 증세 호전되어 퇴원한 2례를 보고하는 바이다. The incidence of Hypertrophic pyloric stenosis (HPS) in premature infants is rare, the presentation is not typical, and the diagnosis delayed due to uncertain diagnostic criteria in abdominal ultrasonography (US). We report two premature infants with HPS diagnosed by US and upper gastrointestinal (UGI) contrast study. Patient 1. A premature female infant (birth weight 1950 gm at 34 week's gestation) with the onset of intermittent vomiting at 9 days of age was evaluated. US was normal at 13 days of life, however, abnormal at 41 days of life (pyloric muscle length 16.5 mm). Patient 2. A premature male infant (birth weight 1470 gm at 29 week's gestation) with the onset of intermittent vomiting at 10 days of age was evaluated. US showed pylorospasm at 11 days of life, however, findings compatible with HPS at 57 days of life (pyloric muscle thickness 11 mm). UGI contrast study at 48 days of life showed similar findings in both cases. Both patients had undergone pyloromyotomy. In conclusion, the diagnosis of HPS in premature infants requires careful follow-up by US and UGI contrast study.

장철호,정철영 인제대학교 1997 仁濟醫學 Vol.18 No.3

결절성 십이지장염은 일반적으로 내시경 검사상 흔치 않은 소견으로 최근 말기 신장 질환과 연관이 있는 것으로 알려지고 있다. 본 연구는 위내시경 검사상 결절성 십이지장염 소견을 보인 소아들을 대상으로 임상 증상, 동반된 내시경 검사 소견, 조직학적 소견 등을 조사하였다. 결절성 십이지장염은 소아에서 비교적 흔히 관찰되는 내시경 소견이며, 거의 모든 예에서 조직학적 염증 소견이 관찰되지만 만성 반복성 복통과 같은 임상 증상과의 관련성은 확실하지 않다. Nodular duodenitis is endoscopically characterized by multiple erythematous nodules in proximal duodenum and may represent a valiant of duodenal inflammation. This study examines the incidence, clinical presentation, endoscopic finding, and histologic feature of nodular duodenitis in 91 children who presented with gastrointestinal symptoms. Endoscopically, in addition to nodular duodenitis, esophagitis was found in 6% of patients and gastritis in 33%. Histology of duodenal nodules revealed chronic inflammation in 91% of patients, lymphoid hyperplasia in 6%, and normal mucosa in 3% of patients. We conclude that nodular duodenitis in children is relatively common and is an endoscopically distinct entity that is associated with chronic inflammation.

정경미,장철호,정철영 인제대학교 1996 仁濟醫學 Vol.17 No.2

최근에 와서 장중첩증의 조기 진단과 적절한 치료로 예후가 현저히 좋아지긴 했으나, 아직 근본적인 원인과 위험인자들을 예측할 지표는 확실하지 않다. 이에 저자들은 1994년 1년간 상계백병원 소아과를 내원하여 장중첩증 의심 하에 복부초음파를 시행한 218명을 대상으로 하여 장중첩증의 임상 증상 및 검사 소견들을 조사하였다. To evauate the clinical analysis associated with intussusception in children. We studied 218 patients who had taken abdominal ultrasonography, impressed intussusception, at Sanggye Paik hospital during 1 year period January 1994 to December. The results were as follows ; 1.The mean age was 1.45 years old, the most common age are under 1 year old.(41.1%) 2.The sex ratio was 1.7:1, male predominant. 3.The number of intussusception with 3 symptoms(abdominal pain or irritability, vomitting, current jelly stool) was 63 cases, two symptoms(abdominal pain, bloody stool) was 27 cases and 3 cases had only one symptom(vomitting or bloody stool) but they were intussusception. 4.Of the 53 cases with palpable abdominal mass, 47 cases were intussuscetion. 5.Of the 218 cases undergone abdominal ultrasonography, 149 cases were intussuscetion 6.The most common associated diseases was upper respiratory tract infection. 7.Of the 146 cases with intussusception, 119 cases were reducted by gastrographin enema, 26 case were failed, 1 case was reducted by manual method. 8.Of the 26 cases, failed by gastrographin reduction, 20 cases were reducted by surgically manual method and 5 cases were spontaneously reducted, 1 case were resected.
