鄭鉉丞 진주산업대학교 1984 論文集 Vol.22 No.-

This experiment was conducted to investigate the effect of substituting Briquette ash feeding for the second Fe injection of pig at Sucking on pig growth, pig weight at 21 days, pig weight at weaning and pig growth at growing and fattening with 7 pigs of same litter produced at animal farm, this college from March 2, 1984 to July 19, the same year. Pig weight at 21 days was heavier in the pigs feeding Briquette ash after injected Fe once than that in those injected fe twice and conversely, in pig weight at weaning. The body gain of growing and fatterning period was superior in the pigs feeding Briquette ash after injected once of groups studied. Feed efficiency of growing and fatterning pig was higher in the pigs injected Fe twice than that in those feeding Briquette ash after injected Fe once. Pig health in feeding Briquette ash was normal. The results obtained in this study suggest that Briquette ash feeding as substitution for Fe injection be an effective micro­mineral matter from growing to fattening.

This experiment was carried out to determine the yield, chemical composition and feeding value of the leaves and rhytidome of Broussonetia kaxirtoici, Sieb. The feeding value of the leaves fed liberally to growing-finishing pigs was determined under the restricted feeding in which the daily allowance of formula feed was 3 % of body weight, compared with 4 % in the controls. Ten pigs of the same litter were alloted in equal numbers into the control and experimental groups and conducted the feeding trial for 2 months. The results obtained are summarized as follows : 1. The annual yield of green leaves of Broussonetia kazinoki, Sieb. grown on the College Experimental Farm was averaged about 2,000㎏/10a. 2. The chemical composition of the leaves was determined on the dry matter basis as follows ; crude protein : 11.4%, crude fat: 4.74%, crude fiber : 32.33%, crude ash : 13.43% and nitrogen free extracts : 37.16%. 3. The chemical composition of the rhytidome was determined on the dry matter basis as follows ; crude protein : 13.43%, crude fat : 5.94%, crude fiber : 33. 19%, crude ash ; 33.60% and nitrogen free extracts : 27.26 %. 4. The body weight gain for 2 months was averaged 33.8㎏ and 36. 2㎏ in the control and experimental pigs, respectively. However, there was no significant (P$lt;0.05) difference in body weight gain between two groups. 5. The feed conversion was improved slightly in the experimental group(3.2) as compared with the control (3.8). 6. The liberal feeding of the green leaves resulted in the decrease of about 60 won in the feed cost for 1 ㎏ body gain of the growing-finishing pigs. 7. The leaves were found palatable to the pigs and the pigs fed the leaves were found to be normal clinically.

육성돈에 있어서 Russian Comfrey 의 사료적 이용가치

정현승,곽종형,강대진 한국축산학회 1968 한국축산학회지 Vol.9 No.2

The experiment was conducted to determine the feeding value of Russian Comfrey (Symphtyum peregrenium) by growing pigs. Sixteen Berkshire gilts were alloted into 4 treatments according to the levels of Russian Comfrey (R.C.) in pig ration such as 0%, 10%, 20%, and 30% on air-dried basis. Body weight gain, feed efficiency, economical feeding value and palatability in each treatment were investigated. The experimental results obtained were as follows; 1) In weight gain the pigs fed 10% R.C. ration showed more gain (P$lt;0.05), but those fed 30% R.C. ration showed less gain (P$lt;0.05) than control group of pigs did. And the pigs fed 20% R.C. ration showed no more gain than the control pigs statistically. 2) Feed efficiency in 10% R.C. ration was also higher than that in any other rations. 3) Feed cost per ㎏. weight gain was lowest in 10% R.C. ration and slightly higher 30% R.C. ration than that in control ration. 4) From the feed intake it was considered that Russian Comfrey should be considerably palatable to pigs. And from the above results, it was estimated that Russian Comfrey could be supplemented by 20% in the pig ration successfully.

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.

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.

감정 표현 규칙의 인식과 직무 만족 및 직무 긴장 사이의 관계 연구

정현승 한국경영교육학회 2012 한국경영교육학회 학술발표대회논문집 Vol.2012 No.12

많은 서비스 산업에서 감정 표현 규칙을 사용하고 있음에도 불구하고 그 동안 감정 표현 규칙에 대한 연구는 부족하였다. 그 동안의 감정 표현 규칙 인식의 연구는 일반적으로 부정적인 결과를 유발한다는 연구 결과가 많았다. 또한 기존의 연구에서는 부정적인 결과를 완화시켜줄 수 있는 조절효과를 검증한 연구는 매우 미비하였다. 따라서 본 연구에서는 연극학적 관점을 차용하여 감정 표현 규칙의 인식이 직무만족과 직무긴장에 어떠한 관계가 있는지 파악해보고자 하며, 고객서비스에 대한 몰입의 세가지 기반 요인의 조절 효과를 통해 감정 표현 규칙의 인식이 직무 만족 및 직무 긴장에 어떤 영향을 미치는지 검증하였다. 국내 모 보험회사 영업사원을 대상으로 한 실증 분석 결과 감정 표현 규칙의 인식이 꼭 부정적인 결과를 유발하지는 않는다는 결과가 나타났으며, 고객 서비스에 대한 몰입의 세 가지 기반 요인 중 정서적 고객 서비스 지향의 조절효과는 직무 긴장을 완화해 줄 수 있으며, 규범적 고객 서비스 지향은 직무만족을 증가 시킬 수 있다고 나타났다. 또한 계산적 고객 서비스 지향은 직무 만족을 떨어뜨린다는 결과가 나타났다.

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%).
