경상대학교 교내에 설치되어 있는 1-2W형 온실을 대상으로 전기 방열기를 이용하여 국화 재배온실의 난방효과를 검토한 결과는 다음과 같다. 실험기간동안 최고, 평균 및 최저 외기온은 각각 -3.8~21.3℃, -5.2~16.1℃ 및 -12.5~14.4℃ 정도의 범위로 나타났으며, 온실 내외의 평균상대습도 각각 43.5~98.6% 및 35.2~100%로 나타났다. 12월 중순부터 2월 상순까지 최저 외기온은 대략 -5.0~-10.0℃ 전후로 나타나 진주기상대의 최근 자료와 비교하면 상대적으로 최저기온이 낮게 나타나는 경향이 있었다. 야간의 경우, 방열기 직하부의 엽온이 방열기 중간 지점에서 측정한 엽온 보다 크게 2~3℃정도 높게 나타나거나 또는 미미하지만 약간 높게 나타나는 경향이 있었다. 근권부의 경우, 직하부나 중간 지점에서의 온도 차이는 거의 없는 것으로 나타났고, 근권부의 최고온도와 기타 최고 온도의 발생 시점을 보면, 약 2시간정도의 지체현상이 있음을 알 수 있었다. 그리고 실험기간동안 난방에 소요된 총 소비전력량, 공급에너지 및 총 난방비는 각각 2,800kWh, 2,408,000kcal 및 112,000won 정도였다. 화석연료인 경유로 난방할 경우, 총 난방비는 224,500won 정도였다. 방열기를 이용하여 난방할 경우, 난방비를 약 50% 정도 줄일 수 있을 것으로 판단되었다. An analysis in heating effects of an electric radiator located in a 1-2W type chrysanthemum (3 cultivars) cultivation greenhouse installed in Gyeongsang National University drew the following conclusions. During the experiment period, the highest, average, and the lowest outside temperatures were in the ranges of -3.8~21.3℃, -5.2~16.1℃ and -12.5~14.4℃, respectively, and the average relative humidity inside and outside the greenhouses were in the ranges of 43.5~98.6% and 35.2~100%, respectively. From mid-December to early February, the lowest outside temperature was recorded as approximately -5.0~-10.0℃, which showed that it tended to be relatively lower than the temperatures recorded at the Jinju Meteorological Observatory. During the night, the leaf temperature measured directly under the radiator tended to be higher by 2~3℃ than that those at the middle point of the radiator, or higher by anegligible amount. In the case of root zone temperature, it was found that there was almost no difference between temperatures of the part directly under and the middle point, and the time when the highest temperature of root zone and other highest temperatures took place showed that there was about a 2-hour delay phenomenon. The total electricity consumption, energy supply and total heating cost during the experiment period were 2,800 kWh, 2,408,000 kcal and 112,000 won, respectively. When diesel, a kind of fossil fuel, was used as heating oil, the total heating cost was around 224,500 won. It was estimated that the total heating cost could be reduced by around 50% if a radiator was used.

Upper gastrointestinal bleeding is common and potentially life threatening medical emergency. Emergency endoscopy is the first choice of diagnostic and treatment measure for patients with active upper gastrointestinal bleeding. Histoacryl should be considered a second-line treatment modality when conventional treatments were failed. However, it might cause several complications. Herein, we report a case of acute pancreatitis developed after histoacryl injection therapy for active duodenal ulcer bleeding. A 71-year-old man was admitted with melena and hematemesis. On emergency endoscopy, a 2 cm sized active ulcer with bleeding from an exposedvessel was seen at the duodenal bulb. Attempts to arrest the bleeding with hemoclipping and submucosal epinephrine injection were tried, but failed. We changed the method to endoscopic histoacryl injection, and obtained hemostasis immediately. A few hourslater, after successful hemostasis, patient complained diffuse abdominal pain. Ultrasonography revealed hyperechoic heterogenous diffuse pancreatic enlargement and right pararenal space fluid collection, this ultrasonographic findings and elevated serum pancreatic enzymes are compatible with acute pancreatitis.

This study into the classification and vocabulary in postposition of Korean Language as are example for the unification of school grammer. 1. In school grammer a postpositon is divided into a case postposition and auxiliary postposition, and complex postposition added to them. 2. Case postposition should be classified on the standard of the substances' syntax function and classified contents and vocabulary ought to maintain close relation with those of syntax component. 3. All postposition except case postposition, which has the function of helping the meaning in syntax, ought to contained as an auxiliary postposition and not to be detailed-inferior classification-seperately. It may be explained in the process of grabing the meaning of sentence. 4. It is important to teach auxliary postposition an another characheristics, because it keeps the function of illuminating the meaning of sentence and adding the emotion of students.

젖소 말초혈액 림프구로부터 소백혈병 바이러스 배양 및 전자현미경적 관찰

윤순식,박중원,변재원,강문일,유한상,한홍율 韓國電子顯微鏡學會 2005 Applied microscopy Vol.35 No.1

국내 젖소의 54.2%가 BLV에 감염되어 있지만 현재까지 국내에서는 소백혈병 바이러스 (BLV) 입자를 확인한 연구 보고가 없기 때문에 BLV 항체 양성 소의 말초혈액림프구를 배양, BLV를 발현시켜 전자현미경으로 바이러스 입자를 검출하였고 배양조건에 따른 바이러스 발현율 및 발현 시간을 비교하였다. 검사 결과 전형적인 C-형 바이러스를 확인할 수 있었으며 BLV 단크론 항체를 이용한 면역염색결과 BLV 항원 양성으로 확인되었다. BLV 는 대부분 세포 외부에 분포하고 있었으며 세포질 막에서 생성, 발아되어 나오는 것도 관찰되었다. 전체 바이러스의 크기는 90~100 nm였으며 nucleocapsid는 40~60nm였다. 소태아혈청 (FBS)과 T- 및 B-림프구 분열촉진물질(mitogen)을 각각 첨가하여 배양한 결과 두 군 모두에서 BLV 발현이 확인되었다. Lipopolysaccharide 첨가군은 배양 12시간, Conconavalin A 첨가군은 배양 24시간에 각각 림프구의 10%에서 바이러스가 관찰되었다. 또한 FBS만 첨가한 군과 FBS와 mitogen을 모두 첨가하지 않은 군에서도 관찰되었으나 바이러스의 수는 적었다. 본 연구에서 확립된 BLV 배양 기법을 활용하면 BLV에 감염된 소 중 바이러스를 발현하는 소, 즉 전파능이 있는 개체를 찾아내어 우선적으로 도태할 수 있기 때문에 BLV 감염으로 인한 피해를 막는데 효과적으로 이용될 수 있을 것으로 사료된다. Many studies have been performed on the bovine leukemia virus (BLV) since bovine leukosis had been reported in 1968 in Korea. However, there was no report on the ultrastructural examination of BLV. An attempt to detect C-type viral particles in the cultured peripheral blood lymphocytes of Holstein-Friesian dairy cattle, was made to determine whether in vitro viral expression might be used as a reliable method to identify the cow which is likely to transmit BLV. In transmission electron microscopic (TEM) examination, the virus particles were found predominantly outside of the lymphocytes even though a few particles were also observed within the membrane bound cytoplasmic vacuoles. All of them were C-type particles consisting of a central, electron-dense core separated by a clear area from a limiting envelope with a unit membrane structure. Virus particles were easily detected in the lymphocyte which was cultured with medium supplemented with either T-lymphocyte mitogen (conconavalin A) or B-lymphocyte mitogen (lipopolysaccharide). Identical viral particles, although fewer, were also consistently present in the lymphocytes cultured with medium which was containing foetal bovine serum (FBS) only and which was containing neither FBS or mitogen. By contrast, no virus particle was detected in extensive examination of lymphocytes before culture. In conclusion, the BLV cultivation and detection methods established in this study could be used as a tool to identify and eliminate the cattle which can transmit the BLV.

Objective: Advances in surgical technique, anesthesia and perioperative patient management, coupled with the rapid increase in the population of patients reaching their 60s or older, have led to a signiticant rise in spinal precedures. The objective of this study was to evaluate frequency of the disease, surgical results and postoperative complications of the aged patients who underwent spinal surgeries. Methods : We reviewed all spinal procedures for spinal lesions including degenerative diseases, trauma, tumor and others in patients aged 60 years or older between January 1 1994 and October 1 1998(56 men and 26 women), retrospectively. Final outcome was assessed by telephone interview with the patient or the family in 67.1%(55/82). Results : There were 56 male patients and 26 female patients. There were 57 cases of degenerative diseases, 14 cases of trauma, 5 cases of metastaisis, 4 cases of infection and 2 cases of others. According to the level of surgical procedures, there were 20 cases fo cervical spine, 8 cases of thoracic spine, 54 cases of lumbar spine. Postoperaive complications included the following(17/82): 7 dural tears, 2 sepsis, 2 nerve root injury and 6 others. There were no operation-related deaths. During follow up period, ten patients(12.2%) had died, 45 patients(54.9%) were contacted and 27 patients(32.9%) could not be located. Mean follow up period for the 45 patients contacted was 26.1±15.7 months. Of the 45 persons contacted, 34(75.6%) reported improvement, 6(13.3%) no change and 5(11.1%) aggravation of their preoperative symptoms. Conclusion: Spine surgery in patients aged 60 years or older has higher complication rate compare to the younger but it is reasonable to consider the surgical procedures even in the elderly if it is needed. We should give attention not to tear the dura during the surgical procedures, especially in the elderly.

貴金屬·寶石加工産業의 經營實態와 國際競爭力 分析 : 裡里 貴金屬·寶石加工團地를 中心으로 Focusing on Iri Jewellery & Gems Export Industry Park

尹忠沅,崔宇琮,尹錫玩,卞在權 全北大學校 1988 論文集 Vol.30 No.-

Jewellery & gems industry has been developed with the beginning of ancient human history as all the mankind have a fancy for precious metals and stones regardless of the times and nationality. Historically, Korean also had an excellent workmanship from the ancient era and shipped it, as a tribute, to the neighboring countries. However, our deposits of gold and silver had been almost dried up, especially owing to a lot of excavation during Japanese imperialist rule, And precious stones have not been discovered in Korea except a small quantity of crystal. Therefore, Korea cannot but depend on the processing industry of jewellery and germs by importing the unworked gold, diamond and other precious stones from overseas countries. By the way, recent overseas market of jewellery & germs is very extensive and the value added of the industry is much larger than other industries. So jewellery & gems processing industry is regarded as the most important field in the advanced countries. All the more, the industry is typical of labor-intensive one and is more suitable to the nations whose people are deft-handed. From those points, it is quite appropriate to Korea. Recognizing this facts, Korean government had set up a Jewellery & Gems Export Industry Park in Iri city ten years ago. The bonded industry park has much contributed to export promotion and regional economic development. But there are a lot of room for improvement if we would obtain the anticipated results. So we researchers have studied and analyzed the following points to find some ways for improving the Iri Jewellery & Gems Export Industry Park. ① the history of precious metals & gems industry in both overseas countries and Korea. ② international production status of unworked precious metals & stones, and structure of international trade. ③ business status of exporting companies in Iri Jewellery & Gems Export Industry park; general circumstances, exprot & import structure, employment policy, production & skill, purchasing materials (the unworked stones ) and marketing etc.

Primary aldosteronism is a syndrome characterized by hypertension, hypokalemia, suppressed plasma renin activity, and elevated serum aldosterone levels. Conn first described it 1955 in association with adrenal cortical adenoma(Conn's syndrome). Today, it can be divided into at least six distinctive sub-groups. The diagnosis of primary aldosteronism is usually suspected when the patient presents with poorly controlled hypertension with hypokalemia. The main issues in the evaluation of primary aldosteronism are to differentiate an adenoma from hyperplasia and to localize the adenoma. Basic hormonal studies and computed tomographic(CT) scanning can be used effectively for that differentiation. An adenoma is one of a few potentially curable forms of hypertension, and it is best treated by removing the adrenal tumor. We experienced a case of a typical adrenal adenoma. The patient was a 37-year-old male who had experienced in both his legs over a period of several days a weakness due to hypokalemia. He was diagnosed using basic hormonal studies and adrenal CT scanning. After, he received laparoscopic adrenalectomy and was discharged with improved condition.
