This study is a single case study that analyzed the effects of animal-assisted therapy (AAT) on a 5-years-old male child diagnosed with autism spectrum disorder class II. To verify the analysis, the Korean Childhood Autism Rating Scale Second Edition (K-SCAR 2), which measures the degree of autism, and the EHWA – Check List for Autistic Children (E-CLAC) scale, which is a behavioral development evaluation scale, were used. The AAT program consisted of a total of 12 sessions, for 50 minutes per session, and was carried out once a week for 12 weeks. As a result of the therapy, the autistic child showed increases in the frequency of word use along with increased language use and behavioral interactions. A K-SCAR 2 test was carried out and the results indicated that the child’s autistic condition had improved from severe autism to moderate autism bordering on minor autism. The E-CLAC indicated that the ability of the child to socially interact had improved as his human relationships were improved and the frequency of language use had increased. In conclusion, the results of this experiment indicated that when AAT was implemented with a child with autism spectrum disorder, the level of autism was lowered, while his human relationships improved as well as his language and use behavioral interactions.

This study seeks to compare the economic feasibility and slaughter weight of beef cattle produced based on in vitro embryo. To this end, the study compared and investigated the grade rate of carcasses based on embryo transfer and artificial insemination; slaughter weight, carcass grading results, meat quality and quantity. With respect to the meat grades of carcass based on embryo transfer and artificial insemination; 50.0% (5/10) of embryo transfer-based carcasses were graded with 1++; and 50.0% (5/10), 1+, indicating that 100% (10/10) received at least 1+ grade. On the other hand, artificial insemination-based castrated cattle had no 1++ grade while 30.0% (6/20) received 1+; 60.0% (12/20), 1; and 10.0% (2/20) 2. This finding showed that embryo-based castrated cattle had higher grades than artificial insemination-based cattle as 100% of the former were graded with 1+ or higher. This study also investigated 10 embryo transfer-based castrated cattle and 20 artificial insemination-based cattle to compare their dressed weight, back fat thickness, sirloin cross section, and meat quantity indication. As a result, the embryo transfer-based castrated cattle showed slaughter weight of 488.4kg on average, heavier by 40.6kg than 447.8kg of artificial insemination-based cattle. Back fat thickness was 15.6㎝ on average in embryo transfer-based cases, 0.9㎝ thinner than 16.5㎝ of artificial insemination-based cases. Sirloin cross section of embryo transfer-based cattle was 99.6㎠ on average, 9.8㎠ wider than 89.8㎠ of artificial insemination cases. Meat quantity indication was found 2.1% higher in the embryo transfer cases (62.8%) than artificial insemination cases (64.9%). With respect to meat quantity grade, 10.0% (2/20) of the artificial insemination cases had Grade A; 50.0% (10/20), Grade B; and 40.0% (8/20), Grade C. Embryo transfer-based cattle showed no Grade A among the 10 carcasses; Grade B in 60.0% (6/10); and Grade C in 40.0% (4/10). Comparing the results of economic profitability in terms of carcass auction prices, the embryo transfer-based castrated cattle was KRW 1,119,453 higher than artificial insemination-based castrated case. Per-head economic gain of embryo transfer-based castrated cattle was KRW 2,282,602, higher than KRW 1,567,149 of artificial insemination-based cattle. Based on the findings, this study examined embryo transfer-based castrated cattle and artificial insemination-based cattle to compare their carcass grade rate, dressed weight, grading result and economic feasibility. Consequentially, this study found that in vitro embryo transfer-based castrated cattle had higher meat quality grade, slaughter weight and economic feasibility. Based on information on pedigree, attribute, and carcass data of individual with blood tie which indicate such meat productivity; high grade cattle genetic resources would be secured to contribute to quality meat production. Subsequent study will need to research industrialization based on in vitro embryo transfer.

서로 다른 배양액의 조건이 우수한 등급의 한우의 난소에서 채란한 난포란의 체외 수정란 생산에 미치는 영향에 관하여 실험을 실시하였다. 한우 난자 수에 대한 2세포 난할율은 대조구 86.7%, IVDM 101 배양액 92.9% 그리고 IVD101 배양액 90.1%로 나타났다. 이러한 결과에서 보는 것과 같이 IVDM 101 배양액와 IVD101 배양액이 대조구 보다 높은 결과를 보였으며, IVDM 101 배양액이 IVD101 배양액 보다도 더 좋은 결과를 나타났다. 한우의 체외배양 배반포 배의 발생율은 대조구에서 12.4%, 혈청이 첨가되지 않은 IVMD 101 배양액에서 38.4% 그리고 IVD 101 배양액에서 32.4%로 대조구 보다 매우 높은 결과를 얻었다. 또한 탈출 배반포 배는 대조구, IVMD 101 배양액과 IVD 101 배양액에서의 각각 5.3%, 33.9%, 그리고 28.6%의 결과를 얻었다. 탈출 배반포 배에서는 IVMD 101배양액과 IVD 101 배양액이 대조구 보다 매우 높은 결과를 보였다. 한우 배반포 배의 평균 세포수는 TCM-199+10% FBS 배양액, IVMD 101 배양액 그리고 IVD 101 배양액에서 각각 128.3개, 165.7개 그리고 163.6개였다. 이 결과에서 보는 것과 같이 IVMD 101 배양액 그리고 IVD 101 배양액에서의 세포수가 대조군 보다 매우많았다. 수정란 이숙한 후 소의 임신율은 무혈청 배양액 (39.6%)이 혈청 첨가 배양액 (32.8%) 보다 높은 결과를 보였다. 또한 사산율은 무혈청 배양액 (4.9%)이 혈청 첨가 배양액 (13.6%) 보다 낮은 결과를 보였다. 이상의 결과를 종합해 보면 무혈청 배양액인 IVMD 101 배양액과 IVD 101 배양액이 혈청이 첨가된 배양액 보다수정란의 배 발달율, 배반포배의 세포수 그리고 임신율에 있어서 보다 우수한 결과를 나타냈으며, 특히 IVMD 101배양액이 더 좋은 결과를 보여 이 배양액을 사용하는 것이 매우 효율적이라고 판단된다.
