21세기에 들어 생산성 향상에 크게 기여하는 여성성이 부각되면서 기업 내 여성인력이 증가하고 있다. 이러한 현상은 기업혁신의 주도자이면서 기업 경쟁력의 원천으로 여성을 새롭게 인식함으로써, 여성 CEO의 리더십과 조직 구성원 특성인 조직몰입과 조직시민행동과의 관련성을 파악할 필요성이 강조되었다. 본 연구는 2017년 3월 16일부터 3월 31일까지 서울, 경기에 위치하고 있는 중소기업 중, 여성이 CEO인 기업의 종사자를 대상으로 설문을 실시하였다. 자료분석은 SPSS 20.0을 이용하여 빈도분석, 요인분석, 신뢰도분석, 위계적 회귀분석을 실시하였고, AMOS 20.0을 이용하여 구조방정식 모형과 sobel-test를 통해 가설을 검증하였다. 여성 CEO 리더십은 변혁적 리더십과 서번트 리더십으로 구분하였고, 조직몰입과 조직시민행동은 단일차원으로 구성되었다. 변혁적 리더십과 서번트 리더십은 조직몰입에 정(+)의 유의한 영향을 미쳤고, 변혁적 리더십은 조직시민행동에 정(+)의 유의한 영향을 미쳤으나, 서번트 리더십은 조직시민행동에 유의한 영향을 미치지 않는 것으로 나타났다. 조직몰입은 조직시민행동에 정(+)의 유의한 영향을 미치는 것으로 나타났다. 또한 변혁적 리더십, 서번트 리더십과 조직시민행동과의 관계에서 조직몰입은 매개효과가 있음을 입증하였다. As femininity contributes to enhanced productivity in the 21st century, female human resources have increased in enterprises. The necessity to grasp the relationship between the female CEO leadership, organizational commitment, and the organizational citizenship behavior, which are characteristics of members of the organization, has been emphasized. For this research, a questionnaire survey was conducted on employees of small and medium-sized enterprises which have a female CEO in the Seoul and Gyeonggi-do regions from March 16, 2017, to March 31, 2017. For data analysis, frequency analysis, reliability analysis, factor analysis, and hierarchical regression analysis were conducted using SPSS 20.0, and hypotheses were verified through the structural equation model and Sobel test using AMOS 20.0. The types of female CEO leadership were classified into transformational leadership and servant leadership, and organizational commitment and organizational citizenship behavior were each composed of a single dimension. It was found that transformational leadership and servant leadership had positive (+) significant effects on organizational commitment, and transformational leadership had positive (+) significant effects on organizational citizenship behavior. However, servant leadership had no significant effects on organizational citizenship behavior. It was found that organizational commitment had positive (+) significant effects on organizational citizenship behavior. Also, it was found that organizational commitment had a mediating effect on the relationships between transformational leadership, servant leadership, and organizational citizenship behavior.

To identify the inflow and outflow characteristics of allchthonous organic matters and examine the change of allochthonous organic matter load pattern due to the climate change, we investigated the temporal variations of DOC and POC concentrations within inflow water and dam discharge water and spatio-temporal distribution of POM within the lake water in Lake Soyang which is the largest dam reservoir in Korea in 2006. Most of allochthonous DOC flowed into the lake water during initial rain and was not affected by the amount of precipitation, whereas most of allochthonous POC flowed into during concentrated heavy rain and the concentration of POC was significantly associated with the amount of inflow water and precipitation. Calculated annual allochthonous organic matter loads in Lake Soyang from 2003 to 2006 using the regression equation between the amount of inflow water and the concentration of POC indicate allochthonous organic matter loads are mainly affected by total influx and extreme influx of inflow water. The spatio-temporal distribution of POM indicated allochthonous organic matter of inflow river during flood period in July transported from upper part to middle and lower part of the lake a month later respectively along the middle layer of water column in Lake Soyang.

The Primary production and budget of organic carbon at rainy and dry period was surveyed to evaluate the contribution of primary production in Paldang Reservoir. Primary productivity of phytoplankton showed remarkable differences depending on sampling dates and sites, ranged from 110 to 2,701 ㎎Cm^(-2)day^(-1). In the rainy period of April and August when there had been frequent rainfall resulting short hydraulic retention time and low algal biomass in Paldang Reservoir, autochthonous organic carbon occupied very low ratio, forming approximately 7 percent of total inflow of organic carbon. However in June when it almost never rained and dominant algal species changed from diatoms to green algae and small flagellates, autochthonous organic carbon from primary productivity of phytoplankton formed 29 percent of total inflow of organic carbon.

Purpose: P53 and cyclin D1 have been evaluated as a prognostic marker in papillary thyroid carcinoma (PTC). However, the relationship between p53/cyclin D1 and PTC prognosis has not yet been confirmed. Therefore, we investigated the relationship between p53/cyclin D1 and PTC prognostic factors. Methods: 919 patients with PTC were enrolled. Immunohistochemistry slides were reviewed for p53 and cyclin D1 immunoreactivity. Patients were classified into two groups according to the p53 and cyclin D1 grade: negative for ≤5% and positive for >5%. Medical records were reviewed to evaluate the prognostic factors, lymph node metastatic ratio (LNMR), and MACIS score. We analyzed patients based on p53/cyclin D1(−/−), p53/cyclin D1(−/+), p53/cyclin D1(+/−), p53/cyclin D1(+/+) separately for evaluation of independent effect of p53 and cyclin D1. Results: Mean age of the patients was 49.73 years (range 15∼87), and tumor size was 1.19 cm (range 0.1∼5.0). P53 was positive in 809 (88.0%) and cyclin D1 was positive in 748 (81.4%). Positivity of p53 and cyclin D1 were correlated (r=0.448). There was no statistical significance in MACIS score. Positivity of p53 and cyclin D1 were related with larger tumor size, older age, early T stage, more tumor capsulation, and female. LNMR was higher in p53/cyclin D1(+/−) than p53/cyclin D1(−/−) (P=0.036), p53/cyclin D1(−/+) than p53/cyclin D1(−/−) (P=0.034), and p53/cyclin D1(+/+) than p53/cyclin D1(−/−) (P=0.007). Conclusion: There was no consistent relationship between p53/cyclin D1 and worse prognostic factors of PTC. However, LNMR was higher in p53(+) and cyclin D1(+) cases independently, much more in p53/cyclin D1(+/+) than p53/cyclin D1(−/−).

Granular cell tumors are rare benign tumors that arise from Schwann cells. They are especially rare in the gallbladder; indeed, only four cases have been reported in the English-language literature. This paper reports a granular cell tumor in the gallbladder and is the first such report in a Korean woman. She was admitted to the hospital with jaundice and fever and was diagnosed with acute hepatitis A. While hospitalized, a well-demarcated round mass was incidentally found in her gallbladder. The acute hepatitis A improved with conservative care, but the mass did not change in size after 4 months. The tumor was resected with the gallbladder during laparoscopic surgery, and was found to be a granular cell tumor. The tumor was composed of sheets or irregular fascicles of large polygonal or spindle cells with plump eosinophilic granular cytoplasm that was immunohistochemically positive for S-100 and neuron-specific enolase and negative for neurofilament.

Fine needle aspiration cytology(FNAC) has become a popular method for the diagnosis of a wide variety of both superficial and deep-seated lesions. However, there are few reports about the potential of FNAC for the diagnosis of intraoral lesions. We experienced 44 FNACS from intraoral lesions at Asan Medical Center: 22 from the palate, 6 from the tongue, 5 from the parapharyngeal space, 5 from the lip, 2 from the floor of mouth, 1 from the buccal mucosa, and 3 from other intraoral sites. Histological confirmation was obtained in 32 cases and we analyzed 27 cases excluding 5 cases of inadequate aspirates. Diagnosis was specifically made in 19 of 27 cases(70%) including 1 mucoepidermoid carcinoma, 1 undifferentiated carcinoma, 1 chordoma, 9 pleomorphic adenomas, 1 neurofibroma, and 6 benign lesions. There were three false negative cases(sensitivity, 62.5%) and no false positive cases(specificity, 100%): Two cases diagnosed as "cystic lesion" were confirmed to be mucoepidermoid carcinomas and a case diagnosed as pleomorphic adenoma was proved to be adenoid cystic carcinoma. The results of our study suggest that FNAC is a useful technique in the diagnosis of intraoral lesion.

Helicobacter pylori에 감염된 소아에서 십이지장염, 십이지장 궤양 및 위 상피화생에 대한 전향적 연구

목적: H. pylori에 대해서는 최근 많은 연구가 진행되어 성인과 소아에서 위염과 강한 관련성이 있으며 위 점막은 물론 십이지장 점막에서 위 상피화생이 발생하면 미란과 궤양이 발생할 수 있는 것으로 보고되어 왔다. 그러나 소아에서의 H. pylori 감염과 관련된 십이지장의 조직병리학적 소견에 대한 연구는 아직까지 미미한 실정이므로 본 연구에서는 H. pylori에 감염된 소아에서 십이지장염, 십이지장 궤양 및 위 상피화생에 대한 관계를 규명해보고자 하였다. 방법: 2001년 10월부터 2004년 4월까지 가천의대 길병원 소아과에 내원하여 위 전정부와 위 체부 및 십이지장 점막에서 생검을 동시에 시행한 177명의 환아를 대상으로 H. pylori 감염 여부 및 병리학적 소견을 전향적 방법으로 조사 분석하였다. H. pylori 양성은 조직의 Giemsa stain에서 H. pylori가 발견되었을 때와 H. pylori IgG, urease breath test (UBT), rapid urease test (CLO) 중 2가지 이상에서 양성일 때로 정의하였다. 십이지장염은 hematoxylin 및 eosin 염색에서 간질의 세포 침윤 정도에 따라 제 0도에서 제 3도까지로 분류하였으며, 위 상피화생은 제 0도에서 제 4도까지로 구별하였다. 통계적 분석은 컴퓨터 프로그램 SAS (version 8.1)를 이용하였다. 결과: 1) 대상 환아 177명 중 H. pylori 양성 반응을 보인 환아는 97명(54%)으로 남녀 비는 1.36 : 1이었으며, 평균 나이는 9.66세였다. 2) 십이지장염은 163명에서 확인되었는데 94명에서 제 1도 소견을 보였고 이 중 H. pylori 감염은 47명이었다. 제 2도는 62명으로 이 중 H. pylori 감염은 36명이었으며, 제 3도는 7명으로 이 중 H. pylori 감염은 4명이었다. H. pylori 감염과 십이지장염 간에는 유의한 상관관계가 없었다. 3) 십이지장 궤양은 11명으로 평균 나이는 7.18세였으며 남녀 비는 4.5 : 1이었다. 이 중 H. pylori 감염 양성은 4명, H. pylori 감염 음성은 7명이었으나 통계적으로 유의한 차이점을 보이지 않았다. 4) 위 상피화생은 전체 환자 중 5명으로 이 중 H. pylori 양성은 2명이었으며 십이지장 궤양은 3명이었는데, 십이지장 궤양과 H. pylori 양성이 동반된 경우는 1명이었다. H. pylori 감염과 위 상피화생 발생간에는 통계적으로 유의한 상관관계를 보이지 않았다. 그러나 십이지장 궤양이 있는 군에서 위 상피화생의 발생률이 더 높았다(p=0.032). 5) 십이지장 궤양은 십이지장염 제 1도 94명 중 1명, 제 2도 62명 중 5명, 제 3도 7명 중 5명에서 각각 발생하여 십이장염의 정도가 증가할수록 십이지장 궤양의 발생이 증가하였다(p<0.0001). 6) 위 상피화생은 십이지장염 제 1도 94명 중 2명, 제 2도 62명 중 1명, 제 3도 7명 중 2명에서 각각 발생하여 십이지장염이 심할수록 위 상피화생의 발생이 증가하였다(p=0.0365). 결론: 기존의 문헌들에서와 달리 본 연구에서는 H. pylori 감염과 십이지장염, H. pylori 감염과 십이지장 궤양 및 H. pylori 감염과 위 상피화생 간에는 연관성이 없었으며, 십이지장염과 십이지장 궤양 간에는 연관성이 있었다. 그러나 위 상피화생과 십이지장 궤양 및 십이지장염과 위 상피화생 간에는 기존의 보고들처럼 연관성이 있음을 알 수 있었다. Purpose: Helicobacter pylori (H. pylori) infection has been known to be vital in the pathogenesis of duodenal ulcer disease in children as well as in adults. But the relationship between H. pylori infection and the histopathologic findings of the duodenum has not been explained obviously in children yet. So the aim of this study is to determine whether duodenitis and/or gastric metaplasia in the duodenum increases the risk of duodenal ulcer disease in children infected by H. pylori. Methods: From October 2001 to April 2004 gastric and duodenal biopsies were performed in 177 children who visited Department of Pediatrics, Gil Hospital, Gachon Medical School. Biopsy sections were stained with hematoxylin and eosin and also with Giemsa for identification of H. pylori. The grades of duodenitis and gastric metaplasia were classified from 0 to 3 and from 0 to 4, respectively. Results: The incidence of H. pylori infection was 54% in total patients. Amongst 163 children with duodenitis there was a lack of correlation between H. pylori infection and the grade of duodenitis. Amongst 11 patients with duodenal ucler, only 4 children were infected by H. pylori. And amongst 5 patients with gastric metaplasia, H. pylori and duodenal ulcer were detected in 2 and 3 children, respectively. The occurrence of duodenal ulcer and gastric metaplasia were increased significantly in proportion to the grade of duodenitis (p<0.0001 and p=0.0365, respectively). Conclusion: As opposed to the results of previously reported articles, there were lacks of correlation between H. pylori infection and duodenitis, duodenal ulcer, and gastric metaplasia. So further study hould be done to clarify the effect of H. pylori on the duodenal histopathology in children infected by H. pylori.

Langerhans cell histiocytosis (LCH) is a pleomorphic disease entity characterized by local or disseminated atypical Langerhans cells (LCs) found most commonly in bone, lungs, mucocutaneous structures and endocrine organs. Among different sites, unifocal disease confined to a lymph node (LN) is rare. We report a case of LCH confined to a LN in a 38-year-old male who presented with a 2 cm-sized cervical mass. The fine needle aspiration (FNA) smears of cervical LN showed high cellularity having isolated LCs with contorted nuclei and nuclear grooves mixed in multinucleated giant cells, small lymphocytes and eosinophils. Charcot-Leyden crystals were also seen, as were a few dendritic-like cells and intranuclear inclusions. Confirmation of LCH was made by histopathologic studies, positive reactions for S-100 protein and CD1a immunohistochemical staining and by the demonstration of Birbeck granules on electron microscopy. The differentials to be considered include dermatopathic lymphadenitis, sinus histiocytosis with massive lymphadenopathy, Hodgkin's lymphoma and malignant histiocytosis. The characteristic cytomorphologic pattern of LCH in a LN FNA smear plays an important role in suggesting the diagnosis of LCH.

Gastrointestinal autonomic nerve tumor (GANT) in the rectum is a subset of gastrointestinal stromal tumor (GIST). It’s a very rare mesenchymal tumor with neuronal differentiation of gastrointestinal tract. We experienced a 34-year-old female patient with GANT in the lower rectum. She was referred to our hospital owing to rectal bleeding, but didn’t have other symptoms such as abdominal pain and constipation. On digital rectal examination, a round and smooth submucosal tumor at posterior wall of the rectum was palpated approximately 5 cm above the anal verge. The mass measured approximately 5 cm in diameter and was not fixed to the underlying structures. Colonoscopy, abdomino- pelvic computed tomography scan, and core needle biopsy were performed. Given the impression of GIST, it was assumed that the patient underwent low anterior resection with double stapling technique. The tumor, a yellow-grayish colored mass, was homogenous and didn’t have hemorrhagic necrosis. Diagnosis of GANT was based on histological, immunohistochemical staining, and electron microscopy. The patient did not receive any adjuvant therapy and was discharged without complications on the tenth postoperative day.
