In Vietnam, the WHO Framework Convention on Tobacco Control (WHO FCTC) took effect in March 2005 while MPOWER has been implemented since 2008. This paper describes the progress and challenges of implementation of the MPOWER package in Vietnam. We can report that, in term of monitoring, Vietnam is very active in the Global Tobacco Surveillance System, completing two rounds of the Global Adult Tobacco Survey (GATS) and three rounds of the Global Youth Tobacco Survey (GYTS). To protect people from tobacco smoke, Vietnam has issued and enforced a law requiring comprehensive smoking bans at workplaces and public places since 2013. Tobacco advertising and promotion are also prohibited with the exception of points of sale displays of tobacco products. Violations come in the form of promotion girls, corporate social responsibility activities from tobacco manufacturers and packages displayed by retail vendors. Vietnam is one of the 77 countries that require pictorial health warnings to be printed on cigarette packages to warn about the danger of tobacco and the warnings have been implemented effectively. Cigarette tax is 70% of factory price which is equal to less than 45% of retail price and much lower than the recommendation of WHO. However, Vietnam is one of the very few countries that require manufacturers and importers to make "compulsory contributions" at 1-2% of the factory price of cigarettes sold in Vietnam for the establishment of a Tobacco Control Fund (TCF). The TCF is being operated well. In 2015, 67 units of 63 provinces/cities, 22 ministries and political-social organizations and 6 hospitals received funding from TCF to implement a wide range of tobacco control activities. Cessation services have been starting with a a toll-free quit-line but need to be further strengthened. In conclusion, Vietnam has constantly put efforts into the tobacco control field with high commitment from the government, scientists and activists. Though several remarkable achievements have been gained, many challenges remain. To overcome those challenges, implementation strategies that take into account the contextual factors and social determinants of tobacco use in Vietnam are needed.

Users in social media post various types of opinions such as product reviews and movie reviews. It is a common trend that customers get assistance from the opinions in making their decisions. However, as opinion usage grows, distorted feedbacks also have increased. For example, exaggerated positive opinions are posted for promoting target products. So are negative opinions which are far from common evaluations. Finding these biased opinions becomes important to keep social media reliable. Techniques of opinion mining (or sentiment analysis) have been developed to determine sentiment polarity of opinionated documents. These techniques can be utilized for finding the biased opinions. However, the previous techniques have some drawback. They categorize the text into only positive and negative, and they also need a large amount of training data to build the classifier. In this paper, we propose methods for discovering the biased opinions which are skewed from the overall common opinions. The methods are based on angle based outlier detection and personalized PageRank, which can be applied without training data. We analyze the performance of the proposed techniques by presenting experimental results on a movie review dataset.

This study has observed the influence of green advertisemen on the attitude of consumers in relation to its message effect. The analysis has been conducted in the perpective of awareness-emotion -behavior targeting housewives based on the message structure of the advertisement(conclusion omission type/ conclusion offer type). Results of the analysis are as follows : 1) Green advertisement was more effective for the attitude toward advertisement and products than non-green advertisement and in the case of high involvement the conclusion omission message was more effective than the conclusion offer message. 2) Green advertisement was more effective also for the emotion side than non-green advertisement and the conclusion omission message was found more effective than the conclusion offer message. 3) Green advertisement was found more effective for purchasing activities than non-green advertisement and the conclusion omission message was found more effective than the conclusion offer message in the case of high involvement. 4) In case of the conclusion offer type structure of green advertisement the awareness side influenced purchasing activities and in case of the conclusion omission type structure of green advertisement the emotion side influenced purchasing activities. Besides that in case of the conclusion offer type structure of non-green advertisement both the awareness and emotion sides were found to influence purchasing activities. No difference was found in the conclusion omission type structure of non-green advertisement.

Recent research on organizational innovation, such as. new managerial processes, practices, suggests it can be an important source of firm's competitive advantage. The challenge is not only offering new products and services, but also changing the nature of management within organizations. In this study, we focus on management innovation at the organization level and investigate the role of transformational leadership behavior as a key antecedent. Transformational leadership may complement an organization''s increasing rigidity by maintaining a sense of meaningfulness in members of the organization, which may be more flourishing to organizational innovation. Due to its prominent role within organizations, CEO has the ability to greatly influence management innovation. In particular, we focus on leadership behavior and examine transformational leadership of CEO. Additionally, as contextual variables like organizational structure(complexity, formalization, centralization) may influence the impact of transformational leadership, we investigate its moderating role. Findings show that transformational leadership behaviors positively contribute to organizational innovation. In addition, our study indicate that less complex, less formal and less central, organizations have benefit more from transactional leadership in strengthening organizational innovation.

This study examined the income and price elasticities of tourism demand model by using the ARDL models. This paper used the ARDL & ARDL-RECM model based on the annual number of tourists arrivals, GDP and CPI including tourists from the US, Japan and China entering Korea. First, the income elasticity of the US was inelastic and insensitive necessities for long-run US tourists in the ARDL model. China's income elasticity was elastically sensitive luxuries. Second, the US and China's own price elasticities were very elastic to tourism demand in both models. Third, the US's cross price elasticity showed the relationship between inelastic positive substitutes and inelastic negative complements in China in ARDL model. The cross price elasticities of the US and China showed inelastic positive substitutes in the ARDL-RECM model. Fourth, the coefficients of the error correction term were such that the actual sign and the expected sign of the US and China coincided with the negative sign in the ARDL-RECM model. Therefore, first, it can be established in a tourist policy or tourism strategy through income elasticity. Second, we can improve the quality and differentiation of products, recognizing that Korea's tourism price is more elastic than other markets through price elasticity.

Recent rapidly growth in nanotechnolgies is promised novel benefits through the exploitation of their unique industrial and biomedical applications. With increasing utilization of nanomaterials in consumer products, the potential release of nanomaterials into the environment and their impacts on the ecosystem and human health have been the issues of concern. Nanomaterials that was exposed unintentionally in environment might be accumulated in various environmental media, and finally it will be influenced to human and ecosystems. Therefore, it is important to understand the fate and behavior of nanoparticles for understanding effects on environmental media (air, water, and soil phase). Therefore, in this work, we investigated the several cases for environmental exposure of nanomaterials and suggested the direction of further research. In workplace, exposure to air media is dominant, but finally waste and wastewater was moved to the water and soil phase. In addition, we found the existing sewage treatment plant was not suitable to remove completely nanomaterials in wastewater flow. To deeper study, environmental monitoring tool must be developed additionally and we suggested the several analyzing method for aged and pristine physicochemical properties of nanomaterials exposed into environmental media. This review for nanomaterials' exposure to environmental media will be helpful to investigate the environmental fate of nanomaterials and define the suitable treatment method for nano-waste.

The study is examined to illustrate Korea's status in service trade, including travel deficit, outbound travel market, and inbound travel market. This research will also illustrate what factors generate the growth of travel deficit and suggest some alternatives to solve it even if government notes a steady increase in exports of cultural products and programs and entertainment services, driven by the Korean Wave sweeping across Asia. The study suggested some possible alternatives such as growth of travel balance, improvement of low image on Korean tourism, aggressive participation of government, strengthened role of Korean Tourism Organization(KTO), and appropriate control on overseas studies to lessen an increase of travel deficit. In addition, the study concluded, even if a tourism industry includes a higher multiplier effect, the spontaneous participation intention by Koreans themselves and the strong supports from local governments should be another major successful factors to settle down the travel deficit.

There have been growing concerns that Korea's products keep losing their international competitiveness. It is necessary to restore strong muscles of manufacturing sectors. Together, efforts must be made to strengthen the competitiveness of service sector. While wide consensus has been reached on the necessity that Korea's service sector needs overhaul for stronger global competitiveness, it is rather difficult to witness any remarkable improvements. Insufficient performances might result from the protection of the captive markets by the interested parties. The research starts from the proposition that the introduction of MDP will bring down the barriers between the segmented services and promote competition. We provide theoretical analyses and report better performances of major countries which introduced MDP in their soils. Considering the reality, we propose that in the foreseeable future, a MDP in the areas of tax, law and accounting be introduced in Korea because these areas seem to create least conflicts of disciplinary duties due to public purposes. Broader MDPs in other areas may take some more time. There exist, however, some limitations. As MDP has not been officially introduced in Korea, it is almost impossible to directly compare the performances between the pre- and post-MDP in Korea. Data scarcity of business performances of companies also limits the study.

As a revision negotiation on the KORUS FTA has become a national pending issue, this study aims to analyze changes in the trade structure of Korean export industry before and after the KORUS FTA. For the analysis, this study used Market Comparative Advantage(MCA) and Intra-industry Trade(IIT) indexes. Results of the analysis are as follows: First, in analyzing the competitive and complementary relationships of export products using the MCA index, it was discovered that Korea has formed an export-oriented complementary relationship with the United States. Second, the results of analysing IIT showed that Korea has made a low-quality vertical IIT with the U.S. in some items while it has usually made a weak IIT with the U.S.. Based on the results above, this study proposes a few policy suggestions in the following areas: Improvement of competitiveness in trade-deficit service sector, achievement of the balance of profit and loss in goods and service sectors through the revision negotiation of the KORUS FTA, enhancement of competitiveness in competitive and comparative disadvantage items, reinforcement of ability to respond to consumption patterns in U.S. market, etc. in export-dominant items, and pursuit of horizontal-vertical division of labor in comparative advantage items and horizontal division of labor in comparative disadvantage items.
