Orchardgrass, tall fescue, ladino clover, and alfalfa were sown on the plowed native grasslands of 600 to 900m altitude in the Mt. Chiri on September 10, 1970. Germinating date, winter survival ratio, plant length at each time of 5 successive cuttings, and the pasture yield through October, 1971 were observed. The soil properties of the fields were characterized as pH: 5.5 and loamy, and O.M. : 13.3%. The fertilizers such as N, P₂O_5, K₂O, lime, and borax were applied on the fields. And yield of native grasses, which were fertilized or not, was determined. 1. The germinating dates were ranged from September 19 to September 26 and were 2 to 3 days later on the upper lands. Tall fescue was germinated 2 to 4 days earlier than other pasture species and alfalfa was the latest germinating pasture species of them. 2. Orchardgrass showed the highest winter survival ratio (58.6 to 72.2%) and alfalfa showed the lowest (31.6 to 64.5%). The winter survival ratio of alfalfa and tall fescue decreased critically in the fields of 700 to 900 and 900m altitude, respectively. 3. The average plant length of 5 cuttings was ranged from 31.6 to 37.3 ㎝ in the 3 field locations. The shorter pasture grew in the higher altitude. The orchardgrass was longest in all the fields (45.0 to 58.2 ㎝). 4. Orchardgrass showed the most highest hay yield (719 to 825 ㎏/10a) and alfalfa showed the least (645 to 725 ㎏/10a). The native grasses showed the hay yield of 803 to 825㎏/10a in the non-fertilized plot and 877 to 829㎏/10a in the fertilized plot in the first year.

智異山 大單位 緬羊牧場 開發의 必要性

鄭鉉丞 진주산업대학교 1976 論文集 Vol.14 No.-

The impotance of and major problems on the development of some large sheep farms on the Mt. Chir were discussed on the bases of the author's experiences on this subject. through 9 years. 1. Sheep production in the high mountaineous area has a great importance in the view of economical food and wool production with the increased land productivity and utillization of natural resources. 2. The major problems on the developing sheep farms on the Mt. Chiri were considered as follows: 1) Livestock industries are successful only by the longterm developing schedu1e. 2) Sheep production in Korea in general, is one of the underdeveloped livestock industries. 3) Any agricultural industry on the high mountaineous area has much disadvantage in traffical and social conditions. 3. The natura1 conditions were considered good for sheep farming and it was recommended for the succseeful development of sheep farms on the Mt. Chiri that the Government grant a long-term loan of 1ower interest and improve the traffical conditions, the scientists be trained more widely and intensively on sheep farming and the large enterprises have more interests in the development of national land resources.

정현승,김희정,김해성,김상완,신찬수,박도준,박경수,장학철,김성연,조보연,이홍규 대한내분비학회 2007 Endocrinology and metabolism Vol.22 No.4

Background: Recently, the detection rate for adrenal incidentaloma in Korea has been on the increase. We describe here the clinical characteristics of these tumors and describe appropriate guidelines of diagnosis and treatment.Methods: We analyzed age, sex, location, size, function, and the pathological findings for 132 patients with an adrenal mass by CT, USG, and MRI undertaken for health examinations or non-adrenal disease from January 2000 to March 2005. Results: Adrenal masses were most commonly found in patients in their sixties (31%). 62.1% of the patients were men and 37.9% were women. For the location of the masses, 53% were found in the left gland, 43.2% were found in the right gland and 3.8% were found in both glands. Of all of the masses analyzed, 66% were 1 cm to 4 cm in size, and an adenoma-like appearance was the most common finding (69.7%) seen in images. All of the pheochromocytomas and carcinomas were above 4 cm in size. Patients with a functional mass were seen in 18 cases (13.6%) and pheochromocytomas were seen in 12 cases (67%). Three patients were found with cancer (2.3%), two cases (1.5%) of a primary carcinoma and one case of a metastasis (0.8%). Conclusion: The frequency and characteristics of benign nonfunctional, functional and malignant masses that were found in our hospital were similar to those presented in studies conducted outside of Korea. Therefore, it may be possible to apply previously established guidelines to domestic patients. 연구배경: 최근 들어 외국뿐 아니라 국내에서도 부신 우연종의 발견빈도가 증가하고 있다. 그러나 이 종괴의 특성에 대해 많은 외국 보고가 있어 왔으나 국내에서는 몇몇 보고를 제외하고 아직 연구가 충분하지 못한 실정이다. 따라서 국내에서 발견되는 부신 우연종에 대한 특성을 살펴봄으로써 외국에서 보고된 진료나 치료 지침이 우리나라 사람들에게도 적용될 수 있는지 알아보고자 본 연구가 의도되었다. 방법: 대상자는 2000년 1월부터 2005년 3월까지 건강 검진 및 부신 질환과 무관한 증세로 촬영된 CT, USG 및 MRI 등의 검사에서 부신 종괴가 발견된 총 132예를 대상으로 하여 연령대, 성별, 환자의 기왕력, 종괴의 위치 및 크기, 기능성 여부 및 조직학적 소견 등에 대한 빈도를 분석하였다.결과: 부신 우연종을 갖는 132명 중 60대에서 전체 종양의 31%가 발견되어 가장 높은 비율을 차지하였다. 성별로는 남성에서 62.1%, 여성에서는 37.9%가 발견되었다. 좌측 53%로 우측 43.2%보다 약간 높은 빈도였으며 양측성은 3.8%를 나타내었다. 크기에 있어서 1 cm 이상 4 cm 미만 크기의 종양이 전체의 66%를 차지하였고 이중, 69.7%가 영상촬영 소견에서 선종의 양상을 나타내었다. 갈색세포종과 악성 종양은 모두 4 cm 이상의 크기를 나타내었다. 기능성 종양은 132명 중 18명에서 나타났으며 이중 갈색세포종이 12명으로 67%를 차지하여 가장 높은 빈도를 나타냈다. 악성 종양은 132명 중 3명에서 나타났으며 2명은 원발성(1.5%), 1명은 전이성 종양(0.8%)이었다.

지리산 면양목장 조성에 관한 연구 : Ⅰ보. 면양목장 조성 및 면양사육 단지화 조성을 위한 기초조사 Ⅰ. Fundamental Survey of Resources for the Development of Sheep Range and Sheep Farm Grouping

정현승,강봉태 진주산업대학교 1970 論文集 Vol.4 No.-

This survey reports the availability of the various resources such as geography, meteology, traffic condition, soil property, labor resource, pasture distribution and water resource, for the development of sheep range and sheep-farm group, on the first step to the three-year plan in an area around the Forestry Experiment Station of Chinju Agricultural and Forestry Junior Teachnical College in Mt. Chiri. 1. The geographical conditions of the region found to be fit for the establishment of sheep range were as follows; longitude:127˚44'east,latitude:35˚22'north,elevation:600-900m above marine surface level, slope:5-25˚, total area: 280 ha, and administrative district: from high level flats to Yeo-gok and Dusuk village, Yupyung-ri, Samjang-myun, Sanchungkun, Kyung Sang Nam Do, Korea. Especially, eighty seven farm households and Karangip primary school distriduted around this region were found to be the reasonable resources for the development of sheep farm group in this region. 2. The soil of the area was composed of most of sand-loam with PH 5.3∼5.8, 2-5% of grit and 13.3% of humus (4.6-19.3%) among 30∼50㎝ depth of surface soil. These fertile soil properties were found to be fit for the development of pasture. 3. The meteological records of this region were found as follows: frosty period: from October 16 to April 22, yearly mean air temperature: 9.2℃ , ranging from 26.6℃ in August to (-)12 in January, annual rainfall: 2,346mm, yearly mean wind velocity: 6.2m/sec, direction of the wind: north-west in winter and south-east in summer. According to the above results from only one-year observation, the meteological conditions of this region were similar to those of Dae-Kwan Ryung area and were estimated to be favorable for sheep raising. 4. In this region 35 species of wild grasses were prosperous. The green yield of the grasses averaged 1,584㎏ per 10a and 0.87a was required for grazing a sheep. Therefore, it was estimated that about 3,000 heads of sheep would be well raised in this region. The fact that about 30 percent of Mt. Chiri area is available for sheep pasture suggested that 400,000㎏ of wool, or 250,000,000 won in price(equivalent to 1/10 of the total wool imported in 1967)could be gained from grazing about 100,000 heads of sheep in the whole area of Mt. Chiri, 54,000 ha. 5. Sufficient water resources, conclusive of mooring by the farmers around this region, irrigation water, underground water and especially the pond situated in high level flats were found to be available and the quality of water was satisfactory for watering sheep. 6. Concerning the traffic situation of this region, the construction of 1.5㎞ of road to Dusuk village (with 200m of bridge) and three 2㎞ range path from Dusuk village were required. However, such traffic problems are not serious because the sheep farming requires the road only for disposal of wool produced once a year. 7. From the managment survey for 87 farms around this area, it was found that each farm had 1,019.6 hours of unemployed labour per year, which was sufficient for raising 60 heads of sheep. So it could be estimated. that potential labour enough for raising 5,200 heads of sheep was reserved in this area. Moreover, the Karangip primary school boys are available as a good resource of labour for sheep grazing. The great deal of by-products of sericulture and potato-farming, which were the major industries in this region, was available for sheep raising.

煉炭灰魚汁 吸着飼料 添加가 돼지의 血液像에 미치는 영향을 조사하였다. 赤血球, 血色素量, 赤血球容積 및 血液球數는 무처리구에서 높은 편이고, 平均赤血球容積, 平均赤血球血色素量, 平均赤血球血色素濃度는 煉炭灰魚汁 吸着飼料 添加區에서 약간 높았으나, 白血球鑑別計數를 포함한 이들 모든 血液像은 정상치 범위내였다. The objective of this experiment is to investigate the effects of fish-soluble-absorbed-briquette-ash-added feed upon the hematological value of swine. RBC, hemoglobin, hematocrit and WBC were higher in the non-treated group. Mean corpuscular volume, mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration were a little higher in the treated group. And all the above hematological values including differential count were within the normal range.

智里山緬羊牧場 造成에 關한 硏究 : 第11報 : 緬羊飼育適地 細部調査 11. Further Survey for Establishing Sheep Range and Farm Groups

鄭鉉丞 진주산업대학교 1975 論文集 Vol.13 No.-

지리산 지역의 3개소에 대한 면양사육의 적지조사를 실시한 결과 다음과 같은 결론을 얻었다. 1. 조사한 3개소의 위치는 경남 산청군 삼장면 외곡 지역과 삼장면-금서면의 밤머리재 지역 및 시천면 순두류 지역이 었다. 해발은 400∼1,200mm 범위이었고 목야지로 이용 가능한 총 지역은 1,150ha이었으며 이중 초지조성 가능 면적은 35% 로서 450ha이었다. 2. 일반적인 기상, 토양 및 수자원 조사결과는 면양 사육이나 초생에 대하여 양호한 조건을 갖추고 있다고 판단되었다. 일반 야산지대에 비하여 토양유기물 함량은 약 4배나 높은 13.3%이었으나 계속적인 초지관리를 위하여는 3요소의 금비시비가 필요할 것이며 토양 pH는 5.5에 불과하므로 석회의 시용도 필요할 것으로 생각된다. 3. 자연야초에 대한 초자원 조사결과 새, 억새 및 기름새 등의 화본과 야초가 우점된 집단 야초지로서 1년간 20일 주기로 5회 예취한 생초수량은 3,683kg/10a에 달했다. 시비의 효과는 별로 높지 않았고 일반성분 함량도 전국의 평균치와 비슷하였다. 4. 목초재배 시험결과 8월 10일 이전에 파종함이 좋을 것으로 생각되며 오차드 그라스가 가장 내한성이 높았다. 초년도 혼파목초의 생초수량은 600∼900m 지대에서 평균 3,630kg/10a로 나타났다. 5. 야초지에서 면양사육 결과 방목기에는 농후사료의 보충급여가 필요없었으나 월동기 및 번식기에는 보충급여가 필요할 것으로 판단되었다. 이유후 15.5개월간 사육한 결과 일당 증체량은 평균 63∼65g으로 나타났다. 1세양의 산모량은 3.45∼3.43kg으로 양호한 결과라고 생각된다. 10두중3두가 요마비에 감염하여 그중 2두는 완치되었으나 1두는 폐사하였으며 기타의 질병 발생은 없었다. 6. 교통상황 조사결과 외곡지역은 진입도로 1.5km와 교량 50m, 순두류 지역은 진입도로 1.0km와 교량 50m의 개설이 필요하였으며 밤머리재 지역은 진입도로의 개설이 필요하였으며 밤머리재 지역은 진입도로의 개설이 필요없었다. 각 지역에 있어서 목도의 개설길이는 외곡 8.0km, 순두류 16.0km, 밤머리재 11.0km로 추정된다. 7. 인근부락의 농가실태 조사결과 농가는 총 242호로서 외곡지역이 가장 많고 순두류 지역은 가장 적었다. 면양사육을 위하여 필요한 유휴 노동력을 조사한 결과 순두류 지역에서만 2,000두 사육상당의 노력이 부족한 것으로 분석되었다. 이들 농가의 면양사육을 위한 자본조사 결과 총 242호 중에서 자기 자본으로 사육가능하다는 농가는 16호, 일부융자가 필요하다는 농가가 46호 뿐이며 기타는 자본의 여유가 없다고 응답하였다. 8. 면양업의 수익성 분석 결과는 본 연구자와 기타 관련 연구에서 보고된 수익성의 범위가 200두 사육 규모에서 두당 연간 수익성이 4,000∼5,000원으로 추정되며 면양업의 단지화 조성시와 가내 수공업을 병행하고 생산물의 판로 등을 조직화함 으로써 이러한 수익은 거의 100% 이상 증진시킬 수 있는 것으로 판단되어 이들 지역의 농가에서 요구하는 소득수준에 충분한 것으로 분석된다. 9. 면양사육에 대한 기술지도 및 생산물의 유통 기구의 합리적인 방안에 관하여 연구한 결과를 기술하였는데 건전한 면양업 육성을 위하여는 면양진흥연구 협의회를 구성하여 여러 문제의 해결에 적극적인 노력을 함으로써 수익성을 크게 높여야 할것으로 생각된다. 10. 3개지역 면양목장 조성시에 지역농가에 의한 단지화의 경우의 자본에 대한 조사결과 농가의 응답에 의한 자본으로는 2,000두 사육에 불과한 것으로 추정되나 기업목장을 유도하여 초지조성등 적극적인 경우는 자연 조건하에서 14,000두의 사육이 가능한 것으로 추정되었다. The natural and Social factors of three regions in Mt. Chiri were evaluated for establishment of sheep farm groups on the basis of author's previous survey and the present resurvey. The results obtained were as follows: 1. The regions surveyed were located at (1) Oegog, Samjang-myun, Sancheong-kun, (2) Bammerijae, Samjang-Geomseo-myun, Sancheong-kun, and (3) Sunduryu, Sicheon-myun, Sancheong- kun. The total area available for establishing sheep range and grassland in these regions were estimated 1, 150 ha and 450 ha, respectively. Their altitude ranged from 400 to 1,200m. 2. These regions were considered to have the relatively good meteological, soil and water resource for raising sheep and growing pastures. The organic matter content of soil(13.3%) in Oegog reging was almost 4 times as much, comparing with the results reported about most of the hilly lands in korea. However, the spplication of chemical fertilizers including lime was esssential for intensive grassland farming. The pH value of surface soil was averaged 5.5. 3. The vegetation survey showed that the dominant species of native grasses were Arundinella hirta, Miscanthus Sinensis and Eccoilopus cotulitfer. The green yield of native grasses from 5 cuttings with interval of 20 days was averaged 3,683kg/10a. The productivity of native grasses was not inproved greatly by the fertilizers application at least for the first year. The chemical composition pf native grasses in this region was comparable to the over-all country average reported. 4. In the fall-sowing system of Pasture it was considered that the best winter survival resulted from the sowing at earlier than August 10 and orchard grass showed the highest winter survival of the 4 species of pasture examined. The green yield of the mixed pasture of orchard grass, tall fescue and ladino clover was averaged 3,630kg/10a for the first establishment year. 5. The supplement feeding of concentrates to ewes on these native grasslands was considered effective only in the dry-lot feeding for the increase in body gain and in the early breeding season for the inprovement in lamb crops. The average postweaning daily gain of ewes on the native grasslands with or without supplements was 63 to 65 g for the period of 15.5 months. The average fleece yield of yearling ewes on the native grasslands with or without supplements were 3.45 to 3.43kg. Three of 10ewes used showed the symptoms of Lumbar paralysis from which one of them was died and the others were recovered by treaement. No other disease troubles were observed in the ewes for the experimental period. 6. The region of Bammerijae was introduced by the established roadway. But the other two regions were located at intervals of 1.5km in Oegog and 1.0km in Sunduryu from rodway. and both the regions required a bridge to span the river of about 50 m wide. Requirements of within-range pathway or roadway to be established for these regions were estimated 8km in Oegog, 16km in Sunduryu and 11km in Bammerijae. 7. A total of 242 farm households were distributed near these regions with relatively more in Oegog and less in Sunduryu. The labor resource survey showed that the lack of unemployed near-by farm man-power limited the sheep population of about 2,000 heads only in sunduryu. According to the answers of near-by farms the capital resource available for sheep production was very poor. The requirement of loan from the Government was none in 16 farms,partial in 46 farms and full in the others. 8. From the income analysis for sheep production by the previous authors and other reports, the annual net income per head in the flock size of 200 heads per farm was estimated 4,000 to 5,000 won. such a income was con-sidered to be increased at least twice as much by the grouping of sheep farms, domestic wool processing, improved products disposal system and etc. The level of income estimated was considered enough to meet the requirement of neer-by farms. 9. A suggestion to the technical extension system and wool marketing system was made. A sheep production development council by the Government officers, animal scientists and leading farmers concerning in sheep production was suggested to be made up and to solve the various problems in the profit increase of sheep industry. 10. The available capital resource of near-by farms was enough to keep the flock of 2,000 heads only in these regions. However, it was estimated that the natural resources including labor-power in these regions allowed the sheep production of 14,000 heads on the intensively established grasslands.

This study was carried out to investigate the effects of treatment of ammonia(NH_3)-sulfuric acid combination on feed value of rice straw as a ruminant feedstuff. Rice straw was treated with 3% ammonia(W/DM) for at least 45 days and further with sulfuric acid for overnight to complete the combination treatment. The treated rice straw was then sun-dried, and the chemical composition and in vitro digestibility of the treated rice straw was analyzed. Also, three sheep (49.8 kg) were used to determine palatability. The treatments included untreated, ammonia-treated and ammonia·H_2SO_4 combination-treated rice straw. The results are as follows 1. Crude protein content was higher(P<0.05), in ammonia·H_2SO_4 combination-treated rice straw than those of other treatments, but NDF and ADF contents were lower (P<0.05) in ammonia·H_2SO_4 combination-treated rice straw than those of other treatments. 2. Total nitrogen and ammonia nitrogen contents were higher(P<0.05) in ammonia·H_2SO_4 combination-treated rice straw han those of other treatments. 3. In vitro dry matter and crude protein digestibilities were higher(P<0.05) in ammonia·H_2SO_4 combination-treated rice straw than those of other treatments. 4. For estimation of palatability, dry matter intake per metabolize body weight(BW^0.75) for 30 minutes was slightly higher in ammonia-treated and ammonia·H_2SO_4 combination-treated rice straw than that of untreated rice straw, although statistical differences were not observed.

鄭鉉丞 진주산업대학교 농업기술연구소 1997 農業技術硏究所報 Vol.10 No.-

本 硏究는 養豚不況期에 農家維持飼養時의 育成豚에 있어서 飼料費 節減을 爲하여 仔豚에 Russian Comfrey의 생초 및 건초를 配合飼料에 各各 10%를 理區別로 添加給餌하여 日當 增體量, 飼料攝取量, 飼料效率을 調査하고자 실시하였다. 本 試驗에서 얻은 結果를 要約하면 다음과 같다. 1. 日常 增體量은 대조구보다 T1 및 T2구에서 다소 낮은 경향을 나타내었으나 處理區間에 有意的(P>0.05)인 差異가 없었다. 2. 사료섭취량은 대조구에 비하여 T1 및 T2구에서 다소 높았으나 處理區間에 有意的(P>0.05)인 差異가 없었다. 3. 飼料效率은 대조구보다 T1 및 T2구에서 다소 낮았으나 處理區間에 有意的(P>0.05)인 差異가 없었다. 4. Russian Comfrey에 對한 豚의 嗜好性은 良好하였고 Russian Comfrey의 생초 및 건초를 건물기준으로 10%까지 添加給餌 하여도 健康上의 異常은 나타나지 아니하였다. 以上의 結果로서 遊休山地와 耕作地에 Russian Comfrey를 自給飼料로써 生産利用할 때 飼料費節減 飼料效率改善, 豚의 增體效果等으로 養豚 不況期의 農家所得의 維持方案이 될것으로 思料된다. This experiment was conducted to investigate the effect of fresh and dried Russian Comfrey(Symphtyum Peregrenium) feeding on body weight gain, feed intake and feed efficiency of growing pigs. 8 Landrace gilts of the same litter were alloted to 3 pigs in the only concentrate group and 6 pigs in the concentrate plus fresh and dried Russian comfrey. The result obtained were as follows ; Daily body weight gain, feed intake and feed efficiency were no significant(P>0.05) differences among three groups.
