鄭鉉承,姜奉泰,李炳五 진주산업대학교 1971 論文集 Vol.8 No.-

This is the second step report of the three years plan on the development of sheep range in the Mt.Chiri. To investigate the effect of the native grasses in the Mt. Chiri on the growth rate, wool production and economical value of sheep this experiment was carried out for 288 days from June, 29,1970 to April,19,1971. Numbers of experimental animal used in this experiment was 12. The results obtained here were as follows; 1. The sheep used in this experiment obtained approximately 17.0 to 23.2 ㎏. of body weight. However, there was no great difference among each experimental animal in the body gain. 2. 2 to 2.6 ㎏. of diet was consumed a day at the grazing period and 1.4 to 1.5 ㎏. of diet at the housing period. 3. 1.7 to 2.3 ㎏. of wool was produced by a sheep. 4. Health condition of sheep for trial period was largely good. However, 3 of experimental animal was infected with Lumbar Paralysis and 2 was recovered from Lumbar Paralysis by spatonin injection and 1 was died of However, it was difficult for infectious location to assert to infected animal because experimental animal was transport from the livestock experimental station, Goryong J1-branch at Dae Gwan Fyong in June. 5. Approximately 30 kinds of native grasses and legumes can used for ration of sheep. 6. In the chemical composition of native grasses, Dry matter of grasses was approximately contented 90 %. and content of crude protein was 5 to 17 %. Content of crude fiber was 24 to 40 %, and crude fat contented 1 to 2 %, crude 2 %, crude ash contented 4 to 7 %, and that of NFE was 40 to 80 %. 7. 1,645 to 3,331 Won of net income be able to get per sheep for throughout experimental period. According to above results, it was found that it is most profitable for use of feed resources of native grasses speading 5,400 ha. area in the Mt. Chiri to rear sheep. On the other hand, to improve the growth rate, wool production and economical value of sheep by feeding of native grasses in the Mt. Chiri, it must considered problems such as grass improvement, moderate cutting of native grass, supplement of deficient nutrient by single feeding of native grass, technical guidance of sheep feeding and import of good gualified sheep.

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.

본 연구에서는 도살장에서 도살되는 한우의 난소를 적출하여 난소로부터 미성숙 난포란을 회수하여 체외에서 성숙한 난자를 동결정액과 정소상체미부 정액을 처리 방법에 따른 수정 및 체외발달에 미치는 영향을 조사하고자 본 실험을 수행하였다. 도살장에서 도살된 한우의 난소를 채취하여 체외성숙을 시킨 다음 한우 동결정액을 융해하여 B. O.배양액으로 원심분리를 2∼3회 반복하여 동해방지제를 제거한후 CO_2 incubator에서 0∼2시간 동안 swim-up을 유도하였다. 정소상체미부정자는 도축장에서 도살 직후 정소를 채취하여 체외수정에 사용하였다. 체외수정은 수정용 B. O.배양액 80∼100ul 당 10∼15개의 난자를 옮겨 정자의 최종농도가 2×10 exp (6) sperms/ml이 되게 첨가하여 약 24시간동안 CO_2 incu bator에서 수정을 유도하였다. 체외수정이 이루어진 수정란을 회수하여 10% FCS가 첨가된 TCM-199 배양액으로 4-5회 세척하여 monolayer를 형성하고 있는 난관상피세포와 공배양을 시키면서 48시간 간격으로 신선한 배양액으로 교환하면서 수정란의 체외발달을 유도한 결과는 다음과 같다. 체외수정율은 정소상체미부 정자를 사용하였을 때가 66.1%로서 동결정액을 사용하였을 때의 51.3% 보다는 유의적(P<0.05)으로 높았으며, 배반포로의 발달율은 각각 19.6 및 14.3%으로서 이들간에 유의적(P<0.05)인 차이가 없었다. swim-up처리 시간에 따른 수정율은 59.3∼63.4%의 수정이 이루어져 swim-up처리 시간에 따른 수정율은 유의적(P<0.05)인 차이가 없었으며, 체외수정란의 배반포로의 발달율도 13.6∼19.3%가 배반포로 발달하였으나 이들간에 유의적(P<0.05)인 차이는 없었다. The ovaries of Korean native cow or heifers were obtained from a slaughter house and kept on 28∼30℃ and transported to laboratory within 2 hrs. The follicular oocytes were collected follicles. The oocytes were matured in vitro for 24 hrs. in TCM-99 supplemented with 35ug/ml FSH, 10ug/ml LG, 1ug/ml estradiol-17 and granulosa cells at 39℃ under 5% CO_2 in air. The caudal epididymis of Korean native bulls were obtained from a slaughter house and transported to laboratory within 30 minutes. Swim-up of collected spermatozoa and Freezing sperm was layered under 2ml fertilization B. O. medium in two tissue culture tubes and held at a 45℃ angle for 0∼2 hour. They were fertilized in vitro by freezing sperm treated with heparin for 24 hrs., and then the zygotes were co-cultured in vitro with bovine oviductal epithelial cells for 7 to 9 days. The cleavage rate of matured oocytes was significantly(P<0.05) higher after in vitro fertilization in caudal epididyms(66.1%) than freezing sperm(513%). Similarly, the proporation of cleaved zygotes that developed to blastocysts was 19.6% and 14.3% respectively. The cleavage rate and in vitro developmental rate in swin-up period of freezing sperm was similar(59.3∼63.4% and 13.6∼19.3%).

지리산 면양목장 조성연구 2차년도 계획인 70년도의 면양 입식사육과 사료작물재배 가능성 여부를 알기 위한 기초자료를 얻으려고 예비조사로서 69년도에 면양4두를 강원도 대관령 고령지 시험장에서 운반 입식 사육하고 사료작물 7종을 도입재배하여 다음과 같은 결과를 얻었다. 1. 중체량은 학교 면양이 20.6 ㎏, 지리산 면양이 20.5 ㎏로서 성장률로 나타낼 때 지리산 면양의 성장률이 0.3% 높았다. 2. 산모량은 학교면양이 4.9㎏, 지리산 면양이 4.5 ㎏로서 학교 면양의 산모량이 0.4 ㎏ 많았다. 3. 건강상태는 지리산 면양이 학교면양보다 건강하였다. 4. 사료작물의 일반적인 생육상황을 관찰할 때 지리산 학교의 성적에 큰 차이가 없었다. 이상 본 예비조사의 결과로서 지리산 면양 사육과 사료작물 재배에 의한 개량초지 조성에 대한 연구가 가능함을 인정할 수 있었다. 따라서 70년도에 다시 면양 14두, 사료작물 6종을 도입 계속 시험중인 바 좋은 성적을 나타내고 있다. This paper is the report of the second step or the three year plan on the development of sheep range in Mt. Chiri to Elarify the adequate seeding period and suitable cutting frequency of the forage grass. This experimental land was located at 600~900 m above the sea level in Mt. Chiri. The results obtained were summarized as follows; 1. Early of August was exceedingly suitable seeding time and seeding time was later, germination and growth of grasses were worse. It was induced the worst germination and growth to seeding the grasses seed after medium of October. 2. The native grasses could be cut five times a year, the native grasses were cut at 6 ㎝ hight above land surface at first time before the grasses were rough and next time were cut with 30 ㎝ length at 6 ㎝ hight above land surface. 3. One cutting period was 17 days to 23 days, mean was 20 days. 4. Grass length of cutting grass was below or above 30 ㎝ length. According to above results, suitable seeding time of grass was early about a month in this experimental district more than an open field in Mt. Chiri district. Above 5 times cutting grass was more profitable than one cutting or grazing under natural condition because the native grasses could be cut five times in a year. Toda shina (Arunctinella hirta), Miscanthus puprascens, Abrrasusuxi (Ecoilo pus cotulifer) and Various grass species wer growing in this experimental field, and they were ligniflcated after September. Therefore, it is profitable for pasture management that the grass land is devidec. 10 plot, and sheep are fed for three days in a plot during May to October.

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.

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.
