The present study was conducted for the production of transgenic cloned cows by somatic cell nuclear transfer (SCNT) that secrete human prourokinase into milk. To establish an efficient production system for bovine transgenic SCNT embryos, the offset was examined of various conditions of donor cells including cell type, size, and passage number on the developmental competence of transgenic SCNT embryos. An expression plasmid far human prourokinase (pbeta-ProU) was constructed by inserting a bovine beta-casein promoter, a green fluorescent protein (GFP) marker gene, and a human prourokinase target gene into a pcDNA3 plasmid. Three types of bovine somatic cells including two adult cells (cumulus cells and ear fibroblasts) and fetal fibroblasts were prepared and transfected using a lipid-meidated method. In Experiment 1, developmental competence and rates of GFP expression in bovine transgenic SCNT embryos reconstructed with cumulus cells were significantly higher than those from fetal and ear fibroblasts. In Experiment 2, the effect of cellular senescence in early (2 to 4) and late (8 to 12) passages was investigated. No significant differences in the development of transgenic SCNT embryos were observed. In Experient 3, different sizes of GFP-expressing transfected cumulus cells [large (>30 ${\mu}{\textrm}{m}$) or small cell (<30 ${\mu}{\textrm}{m}$)] were used for SCNT. A significant improvement in embryo development and GFP expression was observed when small cumulus cells were used for SCNT. Taken together, these results demonstrate that (1) adult somatic cells could serve as donor cells in transgenic SCNT embryo production and cumulus cells with small size at early passage were the optimal cell type, and (2) transgenic SCNT embryos derived from adult somatic cells have embryonic development potential.

Purpose: This study aimed to develop an intentional rounding protocol to enhance the clinical competence of nursing students. Methods: An intentional rounding protocol for nursing students' clinical practice was developed following the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) model. A convenient sampling method was used to select 23 junior year university nursing students during their clinical practice in adult nursing. The program evaluation included a quantitative assessment (communication and relationship efficacy, empathy, and patient safety competency) and focus group interviews. Results: The intentional rounding protocol focused on the 4Ps (pain, position, potty, and possessions) and encompassed aspects such as level of consciousness, pain management, personal care needs, intravenous injection, oxygen administration, nasogastric/nasoenteric tube care, maintenance of urine collection bags, and the identification of environmental fall risks. Nursing students performed intentional rounding at least twice a day. Following the implementation of this protocol, nursing students demonstrated a significant improvement in communication and interpersonal efficacy. The focus group interviews revealed four main themes: growth of human relationships, acquiring knowledge in and about the clinical field, becoming a nurse, and barriers in reality. Conclusion: The intentional rounding protocol has the potential to enhance nursing students' communication and interpersonal skills during clinical practice and to provide them with positive experiences in nursing clinical education. Therefore, it is recommended that this protocol be incorporated into nursing clinical practice education.

The Journal of Industrial Management Society in Republic of Korea. In order to explore the effect of overseas language training on the development of foreign language accuracy, this study investigates the errors in English compositions produced by 27 Korean university students who received overseas language training for 15 weeks. For data collection, students were made to take two tests, a pretest and a posttest, a semester apart. The differences in composition elements and errors between the two tests were examined and statistical analyses were performed. Results showed that while the average length of the compositions and sentences increased, the number of sentences decreased in the posttest. Also, more errors were found in the posttest where the students tried to construct more complex sentence structures. The students' ability to generate sentences were found to have improved, while their competence in using grammatical elements accurately within sentences did not see great improvement. This implies that overseas language training was not effective for aiding the development of one's grammatical accuracy of a foreign language over a 15-week period for the students.

If examining utilization by completion of National Competency Standards development, efforts are made so as to organize curriculum matched to education or training and perform subjects based on competence unit educationally in specialized high schools, colleges and university. However, National Competency Standards is insignificantly utilized in enterprises and on the spot due to characteristics of occupation type and diversity of process. This thesis intended to measures of safety efficiency improvement of final enterprise through the human resources assessment system of National Competency Standards based enterprise. Therefore, various methodologies were introduced and results of analysis by Balanced ScoreCard method were suggested for policy measures improving final safety efficiency. The results of this analysis are expected to make contribution to improving the effectiveness of the government's industrial safety and health policies through the establishment of systematic safety and health systems according to the risk level of individual business.

The significant role of the national standards has ever been growing as a critical infrastructure of the national competitiveness. Strategic policies for the advancement of the national standards system in Korea are suggested based on the analysis of trends surrounding the national standards at home and abroad. National standards failing in securing international recognition of its technical competence give an adverse effect to the improvement of industry and national welfare. As a most effective way toward the advancement of the national standards system, the national metrology institute should be placed at the top of the national standards system so as to exert its influence with its technical capabilities close to international level. Efforts are to be made to secure international credibility of the national standards through faithful implementation of the requirements of the mutual recognition arrangement(MRA). And, the legal structures should be refined to be in harmony with the global environment.

This study aims to examine the reading materials of high school English textbooks to propose the integration of the literary texts into reading materials in the classroom for development of communicative competence. Five kinds of high school English textbooks were critically examined in terms of three factors -limited text types, deficit of emotional adjectives and non-authenticity- selected by the author as characteristics of non-communicative language teaching materials. With regard to text types, more than half of the reading materials were expository and simple narratives. This imbalance of text types led materials to the deficit of emotional vocabulary. These factors seem to be closely related to the issue of authenticity of reading materials. Compared to the authentic texts, fabricated texts are likely to make reading vapid and boring task. On the basis of these results, some pedagogical suggestions are made.

In the digital society where ICT technology is highly developed, digital literacy is an essential competence for working and living. Developed countries around the world have been working hard to solve the digital divide and improve digital literacy. In this paper, we investigated and analyzed the case of US public libraries for improvement of digital literacy of adults including the older people. To do this, we analyzed the educational program type of digital literacy, education method, and the contents of the program, focusing on the best practices libraries of the program. Many of the educational programs still related to basic computer and Internet technologies, and training programs on Micro Office, e-mail, social media, and smartphone and tablet computing were also high. The most frequent and daily training method was informal point of use, and the content and level of education appeared to be very diverse. For digital literacy training, the librarians of the public library considered librarians' digital competence and retraining to be the most important, and the library facility and the latest equipment to be suitable for the operation of the digital literacy education program.
