This study examined the major precedent variables that could affect e-learning users' attitudes in two highly-networked countries and a sharply-spreading country in East Asia, namely South Korea, Vietnam, and Singapore. This research also reviewed why e-learners were using the Internet for their study and unveiled cross-national differences in antecedents of online activities, motivations, intention to use, and enhancement in performance among three countries. This paper could see if there were any differences in precedents of e-learning among the countries by ANOVA. Plus, the study uncovered that what precedents impacted the follow-ups of e-learning by regression analysis in each country. The paper found out that differences in social and cultural aspect influenced on the precedents and the follow-ups of e-learning among the countries. For example, Korean learners had stronger utilitarian motivations for e-learning while the Vietnamese and the Singaporean did not. Korean and Singaporean learners were more strongly influenced to visit e-learning sites by their friends and lecturers than the Vietnamese.

In this study, a transnational social space which emerges in a rural village of the northern Vietnam called 'Korean Village' is analyzed. The immigrant women of whom the spouses are Korean were forming transnational network with family members through which frequent and active communications took place. At the same time materialistic exchanges were occurring by means of remittance. Like most rural areas where up-to-date life patterns co-exist with outdated ones, the studied region was turning into a transnational social space under the influence of indigenous locallity, culture and other economic factors. Women were found to play a virtual role as resonator in practicing the transnational activity of migration. With the migration routes getting more and more solidified, the evolution of the transnational social space and the role of resonator, the form of transnational migration which makes involved young women look like a sacrifice is ceaselessly expanding around a specific region. This is noticeable because a rural village seemingly far away from internationalization is not only becoming the transnational social space but also a stage of its evolution.

To fabricate white LED having a high color rendering index value, red color phosphor mixed with the green color phosphor together in the blue chip, namely the blue chips with RG phosphors packaging is most favorable for high power white LEDs. In our previous papers, we reported on successful syntheses of $Sr_{2-}$ $Si_5N_8:Eu^{2+}$ and $CaAlSiN_3$ phosphors for red phosphor. In this work, for high power green phosphor, greenemitting ternary nitride $Ba_3Si_6O_{12}N_2:Eu^{2+}$ phosphor was synthesized in a high frequency induction furnace under $N_2$ gas atmosphere at temperatures up to $1400^{\circ}C$ using $EuF_3$ as a raw material for $Eu^{2+}$ dopant. The effects of molar ratio of component and experimental conditions on luminescence property of prepared phosphors have been investigated. The structure and luminescence properties of prepared $Ba_3Si_6O_{12}N_2:Eu^{2+}$ phosphors were investigated by XRD and photoluminescence spectroscopy. The excitation spectra of $Ba_3Si_6O_{12}N_2:Eu^{2+}$ phosphors indicated broad excitation wavelength range of 250 - 500 nm, namely from UV to blue region with distinct enhanced emission spectrum peaking at ${\approx}530nm$.

지난여름 베트남 남부의 호치민시와 인근의 공장지대는 전례 없는 파업의 확산을 경험했다. 연구자가 만난 한국기업의 매니저들은 이를 "파업의 도미노 현상"으로 묘사했다. 호치민시 노동조합의 고위간부는 "도이머이(Doi Moi) 이후 노사관계에 가장 혼란스러운 변화가 일어나고 있다"라고 단언하기도 했다. 본 연구는 한국계 다국적 공장을 사례로 1) 최근 파업의 정치경제학적 배경은 무엇인지를 살펴본 다음, 2) 왜 어떤 공장은 최근의 파업의 소용돌이 속에서 상대적으로 안전했던 반면 다른 기업은 그렇지 못했는지, 3) 왜 어떤 공장은 파업의 과정에서 협상을 성공적으로 이끈 반면 다른 기업은 그렇지 못했는지, 4) 최근의 파업이 개별 다국적 공장의 체제에 어떤 사회적, 문화적, 정치적 영향을 미쳤는지 살펴보고자 하였다. 연구자는 연구목적을 위하여 호치민 인근과 동나이에 위치한 약 20여개의 공장을 방문하였으며 서로 다른 특징을 가지고 있는 3개의 섬유공장을 선별하여 현지연구를 실시하였다. 이 가운데 첫 번째 공장은 연구자가 90년대 말 현지연구를 실시하여 공장체제의 성격을 잘 알고 있는 다국적 공장이었다. 나머지 두 공장은 재정 상황과 정치과정의 특징이 첫 번째 공장과 대조될 뿐 아니라 서로 다른 공장이었다. 세 공장을 비교 연구함으로써 연구자는 다국적 공장의 재정적 혹은 경제적 상태가 노동쟁의의 성격을 만드는 주요한 조건이 되지만, 회사의 경제적 조건이 양호하고 경영진이 온정주의적 철학을 실천하고 있다고 해서 파업을 미연에 방지할 수 없다는 점을 보여주고자 하였다. 호치민 인근의 파업이 크게는 세계적인 경제위기, 작게는 회사의 재정상태에 영향을 받고 있지만 특정 공장에서 노동쟁의가 일어나는가의 여부는 이 공장의 정치과정과 레짐의 성격에 의해 좌우된다는 점을 밝히고자 했다. 특히 다국적 공장의 정치과정의 안정을 위해서는 '매개자' 역할을 하는 베트남 중간간부, 사무실 직원, 노조간부 등의 역할이 매우 중요하였다. 이들이 위계적으로 그리고 사회문화적으로 다른 외국인 경영진과 공장 노동자의 갈등을 어떻게 흡수하고 중재하는가에 따라 공장체제의 안정 여부가 달려 있었다. 이번 파업은 각각 다른 정치경제적 조건을 가진 여러 공장의 경영진과 노동자가 이러한 사실을 새삼 깨닫게 하는 계기로 작용했다.

This paper aims to investigate the cultural conflicts and characteristics of anti-Korean Wave discourse taken placed among Southeast Asian countries. To do this, it takes Vietnam and Indonesia as the study cases, which have been showing a trend of anti-Korean Wave discourse as well as high popularity of Hallyu. As research methods, the paper analyzes both on-line discourses of anti-Korean Wave and the email audience interviews from both countries. The results show some significant differences between the two countries as well as the similarity that Anti-Korean Wave discourses have been actively produced and disseminated through on-line media. As for Indonesia, the Anti-Korean Wave discourse pivots on the elements clashing between Indonesia's religion and cultural values and Korean consuming culture. According to the Anti-Korean Wave discourse, K-pop contents and entertainers are criticized for damaging the society's morals and cultural identities based on Islamic rules and values. Thus, the sentiment of the Anti-Korean Wave is likely to lead to the cultural nationalism for the sake of their cultural identity. As for Vietnam, anti-Korean Wave discourse mainly consists of issues on enthusiastic K-pop fans' anti-social behaviors and generational conflicts which are presumed attributed as the chief factor of the Anti-Korean Wave. In the Vietnamese discourse, social elites and adults treat the enthusiastic K-pop fans as those who are in need of educational care or psychological therapy. Unlike the Indonesian case, anti-Korean Wave discourse in Vietnam criticized the K-pop and the performer's competence for being cheap sexy and incompetence. They also denounce Korean dramas for their trite, typical story lines, use of excessive emotion, and unrealistic nature. However, the two country's interview participants have in common both acknowledged that rather than considering the Anti-Korean Wave as an issue that needs to be resolved it should be embraced as a natural cultural phenomenon.

The purposes of this study were to examine the current status of ICT in all ASEAN countries and to provide implications for Korea to find appropriate ways to support and collaborate with HEIs in ASEAN countries. To achieve these purposes, ASEAN countries were categorized into 3 groups based on the development stages of ICT, and the key ICT initiatives, current facts about ICT, and related issues were analyzed. The results of the study were as follows: Group 1 countries, Brunei, Malaysia, and Singapore, with relatively well-established ICT infrastructure, have established their own ICT policies and initiated e-learning programs. Group 2 countries, Indonesia, Philippines, Thailand, and Vietnam, which have relatively well-developed ICT infrastructure with existing regional gaps, showed different uses of ICT in higher education. Philippines and Thailand established their own policies based on national ICT master plans while Indonesia focused on MOOCs and Vietnam initiated cyber university projects. Group 3 countries, Cambodia, Lao PDR, and Myanmar, with the least developed ICT infrastructure in ASEAN, have also tried to develop national level strategies to utilize ICT in higher education. However, insufficient and inadequate ICT infrastructure created issues and challenges for these countries to successfully initiate ICT policies. This study suggested that it is necessary to take into serious consideration the national differences when collaborating with and supporting ASEAN countries due to the variation of ICT development stages and different levels of using ICT in higher education among ASEAN countries.

With the rapid development of the Internet, online shopping has grown so fast that almost any good or service can be sold online today. The popularity and rapid growth of e-commerce signal a huge market opportunity for e-retailers. From the organizational perspective, it is necessary to evaluate and explore what drives customers to buy their products or to use their services. This study, therefore, aims to explain the online purchase intention and its determinants of Vietnamese customers for cosmetics and personal care products. Quantitative data was collected from an online survey conducted among university students, then was put into SPSS and AMOS for further analysis. Descriptive statistics, Cronbach's alpha test, exploratory factor analysis (EFA), regression analysis, and SEM were used to examine data from 434 valid answers. The research findings reveal that four factors positively affect purchase intention: Shopping enjoyment has the most significant impact, followed by trust, benefit, and website quality. On the other hand, perceived risk negatively influences purchase intention. While the cosmetics and personal care industry is thriving with a huge number of producers and consumers throughout the world, this study contributes to the existing literature in terms of capturing customers' needs and developing effective strategies to attract more online users.

Korean construction industry made a huge growth over several decades. However, domestic construction market has shrunk in recent years due to the domestic political environments and global economic crisis. Today, the international construction markets become more important to be investigated, and demands for international construction study have risen. The purpose of this study is to search for measures to compare the potential of Southeast Asian countries' construction markets and select strategic target countries where the Korean construction companies pursue to explore for future investments. The research team investigated a range of selection factors which can represent the construction market condition of each country. These factors included the size of the construction industry, economic growth potential, current relationship with Korea, the level of infrastructure development, political situation, etc. After collecting data, each selection factor was scored by experts' analyses and the total score was given to each country. As a result, the rating identified attractive countries for future investments: Myanmar, Vietnam, and Sri Lanka. For the target countries, analytical methods were used for in-depth market analysis that can provide comprehensive insight and strategic clue for development of short-/mid-/long-term roadmap and action plans. The research findings would be used to support rational decision making of construction investment advancing to the Southeast Asian economic growth.

The increased potential for vascular smooth muscle cell (VSMC) growth is a key abnormality in the development of atherosclerosis and post-angioplasty restenosis. Abnormally high activity of platelet-derived growth factor (PDGF) is believed to play a central role in the etiology of these pathophysiological situations. Here, we investigated the anti-proliferative effects and possible mechanism(s) of murrayafoline A, a carbazole alkaloid isolated from Glycosmis stenocarpa Guillamin (Rutaceae), on PDGF-BB-stimulated VSMCs. Murrayafoline A inhibited the PDGF-BB-stimulated proliferation of VSMCs in a concentration-dependent manner, as measured using a non-radioactive colorimetric WST-1 assay and direct cell counting. Furthermore, murrayafoline A suppressed the PDGF-BB-stimulated progression through $G_0/G_1$ to S phase of the cell cycle, as measured by [$^3H$]-thymidine incorporation assay and cell cycle progression analysis. This anti-proliferative action of murrayafoline A, arresting cell cycle progression at $G_0/G_1$ phase in PDGF-BB-stimulated VSMCs, was mediated via down-regulation of the expression of cyclin D1, cyclin E, cyclin-dependent kinase (CDK)2, CDK4, and proliferating cell nuclear antigen (PCNA), and the phosphorylation of retinoblastoma protein (pRb). These results indicate that murrayafoline A may be useful in preventing the progression of vascular complications such as restenosis after percutaneous transluminal coronary angioplasty and atherosclerosis.
