  • The low efficiency of animal production by nuclear transfer technique is considered to be result of an incomplete reprogramming of the donor cell nucleus, which leads to a lack of, or abnormal expression of developmentally important genes. There are a lot of genes related to embryo development and some of these genes are regulated by imprinting. IGF2 (insulin like growth factor 2) and IGF2R (IGF2 receptor) that play important roles in preimplantation development are included in imprinted genes also. (omitted)

  • Originally the concept of the traditional resource sharing has been discussed in the context of bibliographic materials, and has been labor-intensive and high-cost activities. The technology has had a great impact on such pattern of the resource sharing, and has expanded the limited scope of the traditional concept into the sharing of library information in the levels of local, regional and national systems, and expertise, materials, facilities, equipments and personnels of the library system. While the traditional circulation service as a basic method to share library materials by users can provide the resource to a single person at a time, the electronic resource can be shared, by multi-users at a time anytime anywhere. The maximization of the electronic resource sharing requires that publishing process should be fundamentally changed and articles, books, chapters, speech manuscripts, music scores, maps, sound, and other formats of materials should be prepared in machine readable format. This study examined the positive effects of the technology on the resource sharing, but not investigate the concrete and complex problems as to the cost, guidelines, detailed procedures, design details, and intellectual properties and protection involved in the resource sharing. Some findings extracted from the study can be summarized as follows; (1) ILL will lose its meaning as a method to share the materials if they are all in the electronic format and the phrase 'networked information resource' becomes omnipresent. (2) The technology keeps on changing the concept of resource sharing. Today, the scope of resource sharing not only encompasses the sharing of the primary and secondary materials but also the sharing of the processings(eg. cataloging), expertise, user education, special facilities, and the integrated automated library systems. (3) The sharing of the networked resource will be a method to provide better services for library users in the low cost. (4) The a n.0, pplication of the technology to the resource sharing should be focus on the method which allows an end-users to do the direct access to the needed materials, and to be delivered the primary document as soon as possible.

  • Bisphenol A (SPA), a environmental endocrine disruptor, is considered to bind to estrogen receptors and to regulate the expressions of estrogen responsive genes. This study was to evaluate the effect of SPA administration on body weight, sex ratio and litter size on 18 days in prenatal periods, the effect of reproductive organ weight and blood hematological values on 24 days postpartum in pregnant mice. The female mice was administrated to low doses of SPA (0, 0.05, 0.5 and 5.0 mg/kg B.W.) by intraperitoneal injection in gestation days $0\~15$ with 5 times at 3 days interval. The maternal body weight, litter size and sex ratios were similar to in all experimental groups, but body weights of male and female offspring was significantly lower in 5.0mg SPA group when compared to any other groups (P<0.05). No treatment-related effects on body weight, ovary weight and blood hematological values were observed in dams on 24 days after delivery. The uterine weight in 5.0mg SPA group was slightly higher than those of any other groups, but not significantly difference. The histological evaluation of ovary in dam mice on 24 days after dilivery was not difference in all experimental groups, but the endometriosis of uterus in dam mice were significantly increased in 0.5mg SPA group when compared to control group. These results indicates that low concentration of SPA should not be considered as a selective reproductive toxicant.

  • Purpose: The purpose of this study was to measure home health resource utilization using a Case-Mix Adjustor Model developed in the U.S. Method: The subjects of this study were 484 patients who had received home health care more than 4 visits during a 60-day episode at 31 home health care institutions. Data on the 484 patients had to be merged onto a. 60-day payment segment. Based on the results, the researcher classified home health resource groups (HHRG). Result: The subjects were classified into 34 HHRGs in Korea. Home health resource utilization according to clinical severity was in order of Minimum (C0) < 'Low (Cl) < 'Moderate (C2) < 'High (C3), according to dependency in daily activities was in order of Minimum (F0) < 'High (F3) < 'Medium (F2) < 'Low (Fl) < 'Maximum (F4). Resource utilization by HHRGs was the highest 564,735 won in group C0F0S2 (clinical severity minimum, dependency in daily activity minimum, service utilization moderate), and the lowest 97,000 won in group C2F3S1, so the former was 5.82 times higher than the latter. Conclusion: Resource utilization in home health care has become an issue of concern due to rising costs for home health care. The results suggest the need for more analytical attention on the utilization and expenditures for home care using a Case-Mix Adjustor Model.

  • With the increasing popularization of cloud computing, how to reduce physical energy consumption and increase resource utilization while maintaining system performance has become a research hotspot of virtual machine deployment in cloud platform. Although some related researches have been reported to solve this problem, most of them used the traditional heuristic algorithm based on greedy algorithm and only considered effect of single-dimensional resource (CPU or Memory) on energy consumption. With considerations to multi-dimensional resource utilization, this paper analyzed impact of multi-dimensional resources on energy consumption of cloud computation. A multi-dimensional resource constraint that could maintain normal system operation was proposed. Later, a novel virtual machine deployment method (NVMDM) based on improved particle swarm optimization (IPSO) and Euclidean distance was put forward. It deals with problems like how to generate the initial particle swarm through the improved first-fit algorithm based on resource constraint (IFFABRC), how to define measure standard of credibility of individual and global optimal solutions of particles by combining with Bayesian transform, and how to define fitness function of particle swarm according to the multi-dimensional resource constraint relationship. The proposed NVMDM was proved superior to existing heuristic algorithm in developing performances of physical machines. It could improve utilization of CPU, memory, disk and bandwidth effectively and control task execution time of users within the range of resource constraint.

  • University books are an important information resource. University book resources can be shared not only in the traditional paper form, but also electronic form under the background of the Internet. In order to better manage the sharing of electronic book resources in universities, this study put forward three resource sharing strategies: centralized sharing strategy, distributed sharing strategy, and centralized-distributed sharing strategy by analyzing the combined development of books and the Internet as well as the significance and development of book resource sharing. The centralized sharing strategy, however simple, was difficult to handle large traffic; while the resource nodes were independent and self-consistent, the distributed sharing strategy was not easy to find and had a high repetition rate. Combining the advantages of both strategies, the centralized-distributed sharing strategy was more suitable for the heterogeneous form of university book sharing. Finally, a teaching resources sharing platform for university libraries was designed based on the strategy of centralized and distributed sharing, and three interfaces including platform login, resource search, and resource release were displayed. The results of the simulated comparison experiment showed that centralized and distributed sharing strategies had limitations in resource searching and had low efficiencies; the efficiency of the centralized strategy reduced with an increase in search subjects; however, the centralized-distributed sharing strategy was able to search more resources efficiently and main stability.

  • 본 연구는 산란계에 있어 오전오후 사료 분리급여를 위한 실용적 방법을 모색하고자 고칼슘수준(칼슘 3.7%) 사료와 저칼슘사료(칼슘 0.3%) 2가지 기초사료에 석회석을 정확히 칭량한 후 배합사료 위에 고루 뿌려 주면서 0, 10g 및 20g씩을 각각 급여하여 산란생산성 및 계란품질에 미치는 효과를 구명하였다. 시험 전기간 동안 산란율, 난중 및 1일 산란량에서는 처리구간 유의적 차이는 나타나지 않았으나 시험 기간이 지나면서 칼슘 3.7% 수준에서 석회석을 10g 추가 급여한 처리구와 무칼슘 사료에 칼슘 10g 별도 급여 처리구에서 산란율이 개선되는 것으로 나타났다. 칼슘 및 석회석 섭취량은 공급수준이 증가할수록 증가하는 것으로 나타났는데 고칼슘 급여구가 저칼슘에 비하여 다소 낮은 경향을 보였다. 난각강도 및 난각두께는 석회석을 추가 급여한 처리구에서 개선되는 것으로 나타났다. 혈액 생화학분석에서 glucose는 관행수준 칼슘급여량이 칼슘 추가 급여구에 비하여 높은 수준을 보였다(P<0.05). Total protein은 고칼슘 급여구가 상대적으로 높은 수준을 보였으며 Inorganic P은 고칼슘 급여구에서 전반적으로 높았으나(p<0.05), 처리구간 비교 시 일정한 경향을 나타내지는 않았다. 따라서, 결과적으로 본시험에서는 고칼슘 사료 내 석회석의 추가 급여 하였을 때 10g 정도가 적절하였으며 일정기간이 지나면서 생산성 및 계란품질에 있어 개선효과가 나타나는 것으로 알 수 있었다.
