The purpose of this research is to investigate the relationship between global citizenship, self leadership and global health competencies in nursing students and utilize the basic data for development of educational program to increase of global health competence. A convenience sample of 207 subjects were invited from three university. Data were analyzed using t-test, ANOVA and Pearson's Correlation with SPSS PC 18.0 program. Global health competencies showed that there were differences according to religion, taking education related to global health competency, exposure to mass media about global health. There were a significant positive correlation of global citizenship(r=.364, p<.01), self leadership(r=.372, p<.01) and the global citizenship of nursing students showed a significantly positive correlation of self leadership(r=.463, p<.01). Therefore, on the result of this study, when we develop the educational programs to increase the global health competencies for nursing students, we have to include global citizenship and self leadership.

This study aims to theoretically examine the validity of argument that market-opening will improve the audience welfare of media and cultural contents. To accomplish its purpose, first of all, this study classifies the spectrum of approaches on cultural market-opening in Korea. Then, it examines, by the concept of public goods, whether market-opening can bring on economic gains for audience as consumer. Finally, this study inspects the profit and loss for audience as citizen which will be brought on by market-opening on the grounds of democratic value. As a result of this study, the improvement of economic efficiency and competence, the expansion of consumer‘s choices, the preservation of cultural value that the positive approach on market-opening is promising cannot be justified theoretically and logically. Therefore, at least in theoretically, the conclusion that market-opening cannot improve the audience welfare is deduced. However, the objection of market-opening cannot be related to the distorted protectionism of nation culture. On the contrary, this study suggests the condition of market-opening debate must be a opportunity to reconsider and reform of cultural diversity in Korea.

In an era where digital data takes on great importance, images are essential to various media. Noise is generated during the acquisition and transmission of such images, caused by a number of external factors. The removal of noise is an essential step in image processing. There are various methods used to remove noise, in accordance with the cause or form of the noise. AWGN is one of the leading methods. As such, this paper applies the edge detection method using the mean of each pixel after categorizing in detail the partial masks into nine areas as part of the preliminary process, in order to minimize noise that had been added to the image. In addition, the paper suggests an algorithm that applies different filters to the partial masks by using the critical mass value of the transfigured edge detection. To verify the competence of the suggested algorithm, it was compared with existing methods by using magnified images and PSNR(peak signal to noise ratio).

The purpose of this study is to explore the relationship between national reputation, culture and communication based on the intercultural communication theory. The 18 foreign residents in Korea were interviewed. The analysis of in-depth interview reveals that culture and communication are very important factors in establishing the national reputation. The qualitative research showcases that the cultural acculturation types(separation, integration, and assimilation) are grouped as foreigners adapt and acculturate to the residence. Especially, the assimilation is very essential type in having the in-group expectancy and the loyalty to Korea. The results reveal that a higher level of heterogeneity of a personal network('Korean in-group network') is associated with a higher level of reputation and loyalty to Korea. This suggests that having outgroup members in individuals' personal networks facilitates outgroup communication competence and loyalty to Korea.

The competence of callus formation and plant regeneration from root derived callus was higher in japonica cultivars than those of Tongil-type cultivars of rice. A japonica type cultivars Yeongdeogbyeo, showed the highest capacity (13%) for plant regeneration from root calli of 6 cultivars tested. The callus induced from seed and root tissues maintained higher capacity for plant regeneration during 7 passages of subculture on N$_{6}$ solid media at 2-week intervals. The maximum frequency (2 x 10$^{5}$ mL) of round cells and their cell colonies showed about 24 days after suspension culture of root-derived callus in N$_{6}$ medium with lmg/L 2,4-D, 300mg/L casein hydrolysate, 10mM L-proline, 20g/L sucrose and 30g/L sorbitol. The frequency of somatic embryo formation in suspension cultures of root-derived callus increased with prolonged advance of subculture time from 30 to 90 days, but their regenerative capacities decreased.

The objective of this study was to examine the effect of macromolecule in a maturation medium on nuclear maturation, intracellular glutathione (GSH) level of oocytes, and embryonic development after parthenogenetic activation (PA) and somatic cell nuclear transfer (SCNT) in pigs. Immature pig oocytes were cultured in maturation medium that was supplemented with each polyvinyl alcohol (PVA), pig follicular fluid (pFF) or newborn calf serum (NBCS) during the first 22 h and the second 22 h. Oocyte maturation was not influenced by the source of macromolecules during in vitro maturation (IVM). Embryo cleavage and cell number in blastocyst after PA was altered by the source of macromolecule but no difference was observed in blastocyst formation among treatments. Oocytes matured in PVA-PVA medium showed lower rates of oocyte-cell fusion (70.4% vs. 77${\sim}$82%) and embryo cleavage (75% vs. 86${\sim}$90%) after SCNT than those matured in other media but blastocyst formation was not altered (13${\sim}$27%) by different macromolecules. pFF added to IVM medium significantly increased the intracellular GSH level of oocytes compared to PVA and NBCS, particularly when pFF was supplemented during the first 22 h of IVM. Our results demonstrate that source of macromolecule in IVM medium influences developmental competence of oocytes after PA and SCNT, and that pFF supplementation during the early period (first 22 h) of IVM increases intracellular GSH level of oocytes.

This article identifies the problems and substantiates the directions for the development of distance learning technologies in the training of personnel. An example of using digital media to create a remote access laboratory is given. The article is devoted to the definition of the main aspects of the organization of distance education. Rapid digitization, economic, political and social changes taking place in Ukraine necessitate the reform of the education system. First of all, it concerns meeting the educational needs of citizens throughout their lives, providing access to educational and professional training for all who have the necessary abilities and adequate training. The most effective solution to the above-mentioned problems is facilitated by distance learning. The article analyzes the essence and methods of distance learning organization, reveals the features of the use of electronic platforms for the organization of this form of education in different countries of the world. The positive characteristics of distance learning are identified, namely: extraterritoriality; savings on transport costs; the interest of modern youth in the use of information tools in everyday life; increase in the number of students; simplicity and accessibility of training; convenient consultation system; democratic relations between the student and the teacher; convenience for organizations in training their employees without interrupting their regular work; low level of payment for distance education compared to traditional education; individual learning pace; new teacher status. Among the negative features of online education, the author refers to the following problems: authentication of users during knowledge verification, calculation of the teacher's methodological load and copyright of educational materials; the high labor intensity of developing high-quality educational content and the high cost of distance learning equipment; the need to provide users with a personal computer and access to the Internet; the need to find and use effective motivation mechanisms for education seekers.

Human in vitro fertilization and embryo transfer (IVF-ET) program is a general procedure for infertile couples since first successful delivery on 1978 in UK and Korean first on 1985. Recently in Korea, more than 42,000 cases per year of IVF-ET were performed and showed good pregnancy rates compared worldwide data. The human IVF-ET procedure use many consumables, such as ovum pick-up (OPU) needles, centrifuge tubes, culture dish, ICSI pipette, culture media and ET catheters. Major of these materials are supported by the global companies. Thus, Korean IVF-ET program might be placed unstable situation by global economical risks. These uncertain problems could be overcome by the domestic production of IVF-ET materials and consumables. Two times questionnaires for Korean clinicians and researchers about the domestic production were performed and analyzed. Many of them requested domestic OPU needles, ET catheters, culture media and ICSI pipettes under good quality control and quality assurance system. This trial may be contributed to industrialization and to global competence of Korean IVF-ET program. The results of this survey can be provide a fundamental base for development and production of domestic materials and consumables for human IVF-ET program.

The objective of this study was to determine the developmental competence of in vitro matured oocytes after intracytoplasmic sperm injection(ICSI) with epididymal spermatozoa. The ovaries were obtained from slaughtered small species dogs. Oocytes matured in vitro for 24 hrs were fertilized by ICSI with epididymal spermatozoa. After ICSI, one group of oocytes was activated with 2.0 mM dimethylaminopurine or 7% ethanol for 5 min. and second group was not activated. The follicular oocytes were cultured in synthetic oviductal fluid(SOF) and TCM-199 medium containing hormones and 10% FCS for 24~48 hrs in a incubator with 5% $CO_2$ in air at 38.5$^{\circ}C$. 1. Results of IVM showed that the percentage of oocytes reaching MII after 24 h and 48 hrs of incubation were significantly higher(p<0.05) after culture with 48 hrs(9/30, 30.0%) than that after culture with 24hrs(a/30, 26.7%). 2. Results of IVM showed that the percentage of oocytes reaching MII after 48 hrs of incubation were significantly higher(p<0.05) after culture with SOF media(10/30, 30.3%) than TCM-199 media (7/30, 23.3%). 3. The rate of cleavaged embryos to blastocyst obtained by ICSI treated activation oocytes was significantly higher(p<0.05) than that of nonactivation oocytes(5/16, 25.0% vs 1/13, 5.0%). 4. The rates of development of cleavaged embryos to blastocyst obtained by ICSI treated sperm of fresh, epididymal and frozen-thawed epididymal were 8/18(44.43%), 5/16(31.3%), 2/14(14.3%), respectively. and these values of frozen-thawed epididymal sperm injection were lower than fresh sperm injection.
