신인균,박재웅 한밭대학교 2004 한밭대학교 논문집 Vol.21 No.-

PLC programming languages are various from LD(Ladder Diagram), to SFC(Sequential Function Chart), IL(Instruction List) and FBD(Function Block Diagram). Because they use I/O signals of sequence control, it is very difficult to identify operation status in a glance. Consequently, operators cannot troubleshoot easily when problem occurs. In this article, to supplement those disadvantages, an Automatic Supply Machine, the manufacturing machine of rubber roller that yields printer paper, was used for experiment and analysis. Firstly, PLC program was constructed for the operation of Automatic Supply Machine and it was stored in PLC memory. Secondly, a program was written in Visual Basic Program to monitor I/O signals of PLC program. Thirdly, it was compiled to make an executive program and the executive program was placed on 'Desktop'. A new programming method was proposed to perform smooth control and effective operation by monitoring Automatic Supply Machine operation status and troubles with communication between PLC and a computer.

Generally farmers cultivate 2 or 3 crops in a year, In some cases more than 10 crops are culti-vated in a year by a farmer, These crop numbers and varieties also might be changed depending on the farmer's income based on the crop. Therefore, farmers have diHiculty in configurating the recommended for-tilizer rate for each crop. This study developed a series of user-friendly EXCEL Program to help farmers and extension specialists making decision on fertilizer rate for each crop. By using the program farmers can decide appropriate fertilizer rates based on the soil test results for each field and crop, which can improve fertilizer use efficiency. Also, this program might be useful to make a farm plan by reflerting fertilizer tost required for each field.

이재호,김종균 충남대학교 의과대학 지역사회의학연구소 1993 충남의대잡지 Vol.20 No.2

A prospective study was conducted to evaluate the effect of Oraferon on children with recurrent respiratory infection. Study population consisted of 28 children (Group I : 20 children with recurrent respiratory symptoms, Group II : 8 children with recurrent symptoms and nephrotic syndrome). All of patients received 500 milligram or 1000 milligram of Oraferon according to body weight, daily for 2 weeks to 12 weeks in out-patient clinic. The following clinical parameters were assessed according to the severity of cough, dyspnea, sputum in all of them. The mean score of 3 symptoms were highered following the therapy of Oraferon in the treated group. Oraferon worked as immunostinulant, improving the clinical situation in patients with recurrent respiratory infection. We considered that the Oraferon contributed to improve the symptoms of frequent upper respiratory infections and prevent the recurrece of upper respiratory infections in nephrotic syndrome as a coadjuvant therapy.

유재하,이지웅,백성흠,정원균,김종배 大韓顎顔面成形再建外科學會 2002 Maxillofacial Plastic Reconstructive Surgery Vol.24 No.6

The purpose of this article is to confirm the longterm biocompatibility of national Avana implant and international ITI implant in dogs. At the fourth month after extreaction of the mandibular third and fourth premolar in three dog, both implants were inserted using careful atraumatic technique and prosthetic abutments were applied onto the implants in three months. After that, the implants were examined by naked eye and radiographic image every three months during 1 year, for detection of the complications, such as, mobility, bone resorption and wound infection. At 1 year after application of prosthetic abutment, the dogs were sacrificed for the histopathologic analysis by light microscope. The results obtained were as follows; 1. All implants had the ralatively good prognosis without mobility, wound infection and moderate bone resoprtion, in clinical and radiological evaluation during one year. 2. The all histopathologic specimens at one year after application of prosthetic abutment onto the implants showed the distinct osseointegration between implant system and bone, with projection of new bone apposition onto the peri-implant tissue. But Avana implants had the less osseointegration than ITI implants in the cancellous and marrow layer of jaw bone. 3. The all histopathologic specimens at one year after application of prosthetic device showed the firm junction by dense connective tissue pattern between the implant and the gingival portion. But Avana implants had the less firmer junction than ITI implants. 4. The authors confirmed that Avana implant and ITI implant have more higher tissue biocompatibility in dental implantation, but ITI implant has the more osseointegration than the Avana implant.

곽재균,조은기,김행훈,윤문섭,석순종,김창영 한국국제농업개발학회 2004 韓國國際農業開發學會誌 Vol.16 No.2

1. Uzbekistan은 전통적인 농업국가로서 농업이 경제의 축이며 농촌인구가 60%,농업부문 종사자가 전 산업에서 차지하는 비율이 44%이고 농업생산이 GNP에서 차지하는 비중이 33%로서 비교적 높은 편이다. 2. 이 나라의 농업은 강우량이 적고 건조한 기후조건 때문에 주로 관개에 의존하고 있으며 안공수로와 저수지의 건설로 관개가능 면적은 430만㏊ 이고 충분한 수량만 확보된다면 700만㏊ 까지 경작이 가능하다. 농업생산은 목화, 밀, 벼, 포도, 채소, 멜론재배가 주종을 이루고 있으며 특히 일조시수가 3,000시간으로 매우 길고 일사량도 많아 목화, 고품질의 포도와 멜론 생산이 유명하다. 3. 축산업도 농업에서 중요한 부문으로 주로 유목에 의존하고 있으며 염소, 고기소, 젖소, 면양이 주된 가축이고 양잠업도 중요한 위치를 차지하고 있다. 4. Uzbekistan은 맥류, 목화, 포도, 사과, 양파 등의 원산지 일 뿐만 아니라 박과 작물의 2차원산지로서 유전적 다양성이 풍부하고 특히 멜론은 많은 재래종 품종들이 분화되어 재배되고 있다. 5. Uzbekistan는 1995년 한·우즈벡 농업기술협력 가능성 조사 이후 1996년부터 양국간 유전자원 공동연구가 활발히 추진되고 있다 금후 인근 중앙아시아 각국과의 유전자원 또는 농업관련 공동연구를 수행함에 있어 우즈베키스탄을 전진기지로 활용하는 방안이 적극 모색되어야 할 것으로 사료된다. The Republic of Uzbekistan is located in the central part of the middle Asia. The area of the Republic makes up 447.4 thousands ㎢ and about 60% of the country is semi-desert or desert with only 4.5 million hectares of the area cropped. The average temperature in July on the plains' territory varies from 26℃ in the North to 30℃ in the South, and the average temperature in January falls to as low as 0℃ in the South and to -8℃ in the North. Precipitation primarily occurs during the winter-spring period. Annual precipitation amounts to 80-200 ㎜ on the plains, 300-400 ㎜ in the foothills area and 600-800 ㎜ on the eastern and south-eastern slopes of the mountain ridges. Natural pastures occupy 50.1% of the total area of Uzbekistan, and 9.7%(4.3 Min. ha) of irrigated lands. Irrigated land is mainly cultivated for cotton, spiked cereals, rice and potato. Cotton plants occupy 36.5% of the cultivated areas and grain crops 39.5%. Given the abundance of solar radiation and heat, the major factor limiting the use of agroclimatic and land resources is a deficit of water. Agriculture in Uzbekistan was and still is the largest sector in Uzbekistan's economy. Agriculture and it's related industries account for approximately 33% of GDP, and 55% of the hard currency revenues of the country is related to Agriculture. Approximately 60% of the population resides in rural areas, and 44% of the work force is engaged in agricultural production. Uzbekistan is the world's fifth largest cotton producer and the second largest exporter. Cotton has been center to the economy because it accounts for about 50% of the country's export earnings. At the same time, however, cotton production has depended on vast amounts of irrigation, and this has had a possibly significant irreversible negative impact on the Aral Sea. The development strategy in the agricultural sector in the country is targeted at ensuring food and environmental security, while increasing the efficiency and export-potential of domestic production. According to the macroeconomic forecast, the agrarian sector will maintain its leading role in the economy (at 25% of GDP). To meet the strategic development goals by 2010, annual growth in agricultural output must be at least 5-6%.
