갈색 세포종은 신경내분비종양의 하나로 VIP를 포함한 다양한 신경내분비 펩타이드를 분비할 수 있다. 저자들은 만성 설사와 체중 감소를 주소로 내원한 환자에서 좌측 부신에 VIP를 생성하는 갈색 세포종을 진단하여 성공적으로 제거한 후 증상이 모두 호전된 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Vasoactive intestinal peptide (VIP) is a 28-amino acid peptide, which may cause secretory diarrhea by stimulating the production of adenylate cyclase. Neuroendocrine tumors, secreting vasoactive intestinal peptide (VIP), are almost always of a pancreatic in origin. However, a pheochromocytoma may produce several neuropeptides, containing VIP, as they are considered to be neuroendocrine tumors. A 57-year-old woman, who presented with chronic watery diarrhea, hypokalemia, weight loss and a left adrenal mass, is described. Histologically, the tumor was diagnosed as a pheoch-romocytoma, with ganglioneuronal differentiation, and was histochemically confirmed to produce a vasoactive intestinal polypeptide. A left adrenal VIP-producing pheochromocytoma was successfully resected. After surgery, her diarrhea subsided and the electrolytes, affected neuroendocrine hormone levels, blood pressure and blood sugar level were normalized (J Kor SOC Endocrinol 18:227-231, 2003).

It is important to interpret the soil chemical properties in order to effectively manage the farmland. This study was conducted to investigate the soil chemical properties of upland soybean field according to the soil series at 32 upland fields located in the parts of Gangwon-do. Soil sampling sites were selected by using the National Statistics DB and KSIS DB that is a soil environment information system provided by the Rural Development Administration. Soil samples were collected from 0~15 cm of top soil before seeding or transplanting, air-dried, passed through a 2 mm sieve, and analyzed for soil pH, EC, organic matter, available phosphorus (P2O5), exchangeable potassium, exchangeable calcium and exchangeable magnesium. The average chemical properties have exceeded the each nutrient optimum range level of RDA, except the organic matter in experimental soil 2015. And despite application of conventional fertilization, each soil series nutrient contents were change respectively. The results of this study suggest that conventional fertilization should be applied based on the analysis about the amount of accumulated nutrient contents in the soil.

Soft tissue expansion is widely used technique in oral & maxillofacial reconstruction and provide new method of reconstruction in posttraumatic alopecia, post burn, wide scar, congenital deformity, benign tumor, tattoo, etc. Expanded tissue flaps have the advantage of increased vascularity, proximity to the defect, and similarity of color and texture. They also preclude the need to advance flaps from distant sites. Tissue expansion can be used to form a well vascularized cavity to accomodate and nourish bone grafts. The following report describes the uses of tissue expanders by allowing bone grafting to correct both soft and bony defects of mandibular region

Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

도시지역은 과밀개발과 녹지감소로 인해 생태적 기능 쇠퇴, 생물다양성 감소 등의 위협에 처해있으며, 이러한 녹지감소를 해결하기 위해 근린공원 도시공원 등 다양한 공원을조성, 계획, 복원하고 있다. 또한, 도시민에게 자연생태계에서 감상 할 수 있는 생물을 도시공원에서 관찰 할 수 있도록잠자리 연못, 생태습지, 돌무덤 등의 생물서식처를 조성하고있다. 나비는 인간에게 있어 아름다움, 신비로움, 신기함 등다양한 이미지를 제공하며, 관찰, 체험 등의 욕구를 해소하기위해 함평, 남해, 양평, 서울숲 등에 체험관이 설치되어 인기를 얻고 있다. 하지만 대부분이 실내 공간에서 사육되는 나비를 관찰하는 정도에 그치고 있어 정원, 인간, 생물 등이 조화로운 환경과는 다소 거리가 먼 것으로 생각된다. 따라서 본 연구에서는 도시지역의 과밀화와 녹지감소로인한 문제와 생물서식 공간 창출, 및 체험교육 장소 제공등의 다양한 기능을 수행 할 수 있는 나비정원 조성을 위한방안을 알아보고자 연구를 진행하였다. 나비정원 조성을 위해 도입 가능한 목표 나비 종을 선정하고, 선정된 나비가 서식, 생활 할 수 있는 식재식물을 알아보았다. 목표 나비 종은 정원조성 초기에 인위적으로 도입가능하고 교란 및 시행착오 시 재방사가 가능할 수 있도록사육되는 종을 선정하였고 기주식물과 흡밀식물은 해당 종에 대한 국내외 문헌고찰을 통해 분석하고 식물 분류학적구분을 실시하였다. 선행연구를 분석하여 총 4과 16속 21종의 정원 도입 나비를 분류하였으며, 선정된 21종은 호랑나비과(Papilionidae)에서 꼬리명주나비(Sericinus montela), 사향제비나비(Atrophaneura alcinous), 호랑나비(Papilio xuthus), 산호랑나비(Papilio machaon), 남방제비나비(Papilio protenor), 긴꼬리제비나비(Papilio macilentus), 제비나비(Papilio bianor) 등 7종, 흰나비과(Pieridae)에서 배추흰나비(Pieris rapae Linnaeus), 남방노랑나비(Eurema hecabe), 노랑나비(Colias erate) 등 3종, 부전나비과(Lycaenidae) 에서 암고운부전나비(Thecla betulae), 남방부전나비(Pseudozizeeria maha), 푸른부전나비(Celastrina argiolus) 등 3종, 네발나비과 (Nymphalidae)에서 암끝검은표범나비(Argyreus hyperbius), 작은 은점선표범나비(Clossiana perryi) , 먹그림나비(Dichorragia nesimachus), 홍점알락나비(Hestina assimilis), 왕오색나비(Sasakia charonda), 작은멋쟁이나비(Vanessa cardui), 멋쟁이나비(Vanessa indica), 네발나비(Polygonia c-aureum) 등 8종이 분류되었다. 이 종들은 환경변화 민감하므로 생활형에 대한 이론적인 연구가 추가적으로 이루어 져야 함을 언급하였다. 선정 된 21종의 나비에 대한 문헌고찰 결과 총 22과 77속113종 10변종 1품종으로 총 125종의 식물을 목록화 하고그 중 98종이 국내 서식 종임을 확인하였다. 과별 분포는 십자화과(Cruciferae)가 가장 많고 콩과(Leguminosae), 운향과(Rutaceae), 쥐방울덩굴과(Aristolochiaceae), 산형과(Umbelliferae) 등이 주요 종을 이루고 있음을 분석하였다. 국내 미확인 종 17종 또한 비슷한 양상 이었으며, 국내에서서식이 확인 된 종인 고추냉이(Wasabia koreana), 갓(Brassica juncea), 유채(Brassica napus), 배추(Brassica rapa var. glabra), 클레마티티스쥐방울덩굴(Aristolochia clematitis), 데빌리스쥐방울덩굴(Aristolochia debilis), 캠페리쥐방울덩굴(Aristolochia kaempferi), 리토랄리스쥐방울덩굴(Aristolochia littoralis), 마크로필라쥐방울덩굴(Aristolochia macrophylla), 셈페르비렌스 쥐방울덩굴(Aristolochia sempervirens) 자두나무(Prunus salicina), 겨자(Brassica juncea var. crispifolia), 꽃케일(Crambe cordifolia) 등을 사용하여 정원 조성이 가능 할 것으로 판단하였다. 다만, 귀화식물 및 우점(Pest)에 대한 확인이 필요할 것으로 판단하였다. 연구에서 분석한 125종의 식물 중귀화식물이 5과 13종으로 가급적 정원조성에 사용하지 않는 것을 제시하고, 국내에서 재배 중인 국화종류 및 나도냉이(Barbarea orthoceras), 봄나도냉이(Barbarea verna), 유채(Brassica napus) 등으로 대체를 모색하였다. 이와 같은분석을 통해 나비정원 조성에 도입 및 식재 가능한 종 22과59속 74종 10변종 1품종을 도출하여 총 85종류를 제시하고 자생, 재배 및 초본, 목본을 구분하여 향후 계획 및 시공에있어 효율적으로 조성에 도움을 주고자 하였다. 이러한 연구는 나비정원 실증 시험 자료로 활용하고 지속적인 연구를 통해 국가 생물다양성, 나비 보전 및 다양한 생태계서비스 증진자료로 활용하는 한편, 생태교육 장소로서 나비정원 조성과 교육자료 제작에 활용 할 수 있을 것으로 기대한다.

The present research was carried out to evaluate the possibility of increasing female offspring production ratios using artificial insemination buffer (AIB) before artificial insemination (AI). In this experiment, we optimized AIB composition, made an AIB gun and analyze factors affecting AI non-return rate after AIB treatment. The AIB was made with the base of Tris-buffer supplemented with L-arginine and several other chemicals that might reduce the motility of male sperm compared to the female counterpart, therefore, increasing the possibility of fertilization by female sperm. AIB must be deposited into to cervix by AIB gun. After 15 min of AIB deposition, frozen semen was deposited into the same place. A total of 348 cattle were inseminated with AIB insemination, and there were no significant differences between AIB and traditional AI non-return rates (56.8% vs. 55.7%). The AI non-return rate in AIB group, however, differed significantly among 7 Hanwoo farms. The parturition numbers ( to ) of cows did not affect AIB AI rate. The proportion of AIB AI success rates was significantly higher in Hanwoo cows than in dairy cows (61.0% vs. 48.7%), but the average AI success rate did not differ significantly between AIB and conventional AI (56.8% vs. 55.7%). The female offspring production rate in to cervix deposition place was significantly higher than that in the uterus body (77.7% vs. 59.6%, p<0.05). The injection volume of AIB in 5 and 10 ml was significantly higher than that in 2 ml (77.7%, 78.7% vs. 51.8%, p<0.05), but there were no differences in AIB injection volume between 5 and 10 ml. The best exposure time of AIB in the cervix was 10 to 15 min rather than 5 min (79.2%, 77.2% vs. 52.6%, p<0.05). AIB therefore needs to have an exposure time of at least over 10 min for a higher production rate of female offspring. In conclusion, AIB could be used in AI industry to increase the female offspring ratio and AIB AI can increase the AI success rate.
