Published: June 2018

The purpose of this study is to examine the validity of the reported measure of the health of families in China, Korea, health of the family is to analyze the impact on life satisfaction. Family Health castle was used as a measure of Korea (yuyoungju). This study is a family health scale validation study of home economics in South Korea was applied in China (Qingdao region). The generalization of the concept of family health was attempted. Effective research factors in the health of families in South Korea, China, and was based on the assumption that it can be a factor in the Chinese life satisfaction.
Family through the interaction of the family members to form a healthy, family relationships, family centered health care organization, and health activities appropriate to perform an important function. Depending on the health of family factors, life satisfaction research on the impact of gender factors in health (health of family, family esteem and Jewish consciousness, thanks and affection, emotional values, shared goals, role enhancement, problem solving skills, economic stability, kind) in Qingdao, China on the basis of human subjects were analyzed. Measure of health of South Korea’s family translated into Chinese adults in Qingdao, China with 196 people surveyed Korea through factor analysis of the health of the family of the scale factor at the time of development, consistent with the structure factors were confirmed to have.
Therefore, it was confirmed that the factors influencing family health education, income level, number of children through an analysis of the demographic variables and family health outcomes. Showed that the higher the education level and family income level is higher sex health, showed that fewer children will be a higher level of health of the family. Effects also showed a significant effect on life satisfaction than any other variable income or family health sex man appeared to have higher levels of life satisfaction was high, with effects on life satisfaction and demographic factors affect the health of the family.
Family health of this study with demographic variables have a lot of influence on life satisfaction confirmed the point. This study is in accordance with the needs of family health healthy measure of home, such as South Korea, which recognizes the importance of health research to assume that enacted the Act should apply to the (family health Castle) Chinese became meaningful data.
This study is a meaningful survey data by applying to the Family Health Scale Chinese in Korea. It can enhance the understanding of the Chinese people through this research. In addition, the Chinese immigrant women in turn, benefits were provided an opportunity to live satisfying and healthy family life in Korea. Therefore, further study is based on the measure of family health study in Korea and hope that the Chinese people can be satisfied in a more healthy home life forms in progress.
Mean Reversion or Momentum Trades? The VKOSPI Case Study
Authors:   Asia-Europe Perspective Association, Choi Woo Suk , Kim Sung Ho , Choe Kang Suk , Cho Joung Keun
Published: June 2018

For the KOSPI200 Index (“Index”), a well-known negative and statistically significant relationship exists between the returns of the Index and VKOSPI, the official model-free implied volatility index. Our primary research purpose is to test VKOSPI as an informative and meaningful trading indicator and to develop a set of algorithmic trading strategies to time the market.
The trading strategies are evaluated in terms of their ability to develop an algorithmic trading platform that will outperform the index benchmark in falling, rising and steady risk aversion regimes. There is some empirical evidence for expecting opportunities for positive future excess returns for long and short positions triggered by large changes in the VKOSPI. This finding is more prominent during the periods of both rising and steady risk aversions.
Trading strategy in this research is tested on the data period from Jan 2, 2003 to May 29, 2015, using an out-of-sample algorithmic trading platform. We reorganized the data sample into 3 sub-periods: (1) Falling Risk-Aversion Regime: From January 2, 2003 to December 28, 2007 of pre-global financial crisis period of a declining VKOSPI, a positive market return and relatively small VKOSPI fluctuations (P1). (2) Rising Risk-Aversion Regime: From January 2, 2008 to December 29, 2011 as the period of elevated VKOSPI and market stress (P2). (3) Steady risk-Aversion Regime: From January 2, 2012 to May 29, 2015 a very low, consistent VKOSPI with mediocre market returns, especially in Korean equities (P3).
The time-varying return-volatility relation is used to implement a set of dynamic asset allocation strategies by analyzing VKOSPI with its corresponding Index. With asymmetric volatility phenomenon in the Korean stock market, our benchmark-outperforming dynamic asset allocation strategies are effectively developed by processing meaningful signals from VKOSPI on the Index Futures.
Empirical evidence here was not sufficient enough to confirm the short-term profit anomaly suggested by Copeland and Copeland (1999) that the information content in VKOSPI was not for short-term or day traders. It was rather more sustainable for those for up to 9 months’ of investment horizons.
A Study of the Determinant Factors on Economic Growth under Open Macroeconomy
Authors:   Asia-Europe Perspective Association, Kim Seong Suhn
Published: June 2018

Globalization and digital economy are the main keyword which can explain the recent change in the world economy. Through the “creative economy” policy, Korean government has recently concentrated on economic growth and income distribution through globalization. Policy makers believe that openness facilitates the transmission of technology by providing communication with foreign counterparts and encourages firms to invent new and distinct ideas and technologies. Thus, they argue that capital liberalization and international trade and investment could boost the economic growth in Korea.
In this study, I investigate the relationship between multiple macroeconomic variables and economic growth under open economy using the annual panel OECD data during 1985-2012. I employed the endogenous growth model concept using the growth accounting methodology by Cobb-Douglas production function type. The econometric method I used is the panel regression estimation using vector error correction model since there exists cointegration relation among the used variables even though each variable has unit root. Additionally, I examined the long run relationship as well as the short run through the VEC model.
The findings suggest that the devaluation of real effective exchange rate, the increase in private investment, and the accumulation of human capital can encourage the growth of per capita GDP by having significant positive relationship. However, the increase of inward FDI and openness discourages the per capita economic growth in the long run even though positive relationship between trade openness and growth was found in the short run. Furthermore, income inequality may have insignificant effect on per capita economic growth rate.
The findings of this study highlight that appropriate foreign exchange rate policy and encouragement of private investment would be more important than openness policy to economic growth.
Serbian Accession to the EU and CSDP Engagement: Crisis Management in Reworking
Authors:   Asia-Europe Perspective Association, Chun Kwang Ho , Lee Eugene
Published: June 2018

Defence capabilities are a critical part of the European Union’s (EU) holistic policy in the interaction with other entities on the global stage. Despite contemporary challenges, the EU has become a credible agent in the field of crisis management. The development of an integrated security policy, therefore, has become a pivotal task for the Republic of Serbia in order to meet two major national objectives: territorial integrity and its membership into the EU. Despite its troubled history with Kosovo, Serbia is optimistic and looking forward towards European integration. This paper examines the implications of the Serbian accession into the EU’s defence structures for the Common Security and Defence Policy by analysing political and military aspect of the process. Participation in missions under the EU umbrella could contribute to the increased Serbian credibility within the European community and, therefore, contribute to the success of the Serbian National Security Strategy.

Published: June 2018

The research is to estimate the validity of Korea’s annual contribution to the budget for maintaining the United States Forces Korea. Defining the put option as USFK’s role and value in order to confront crisis. It has estimated the strategic value(put premium) of the USFK by determining its price. Approaching the USFK as “Real Options” rather than “Financial Options”. We defined Korea’s economic scale prior to the wartime as “S(Spot price)” and after the breakout in time of US reinforcement as “K(Strike price)”. “K(Strike price)” is based on the Korea-U.S war scenario were calculated by considering loss of the civil and military sector. in this study, “K(Strike price)” is subtracted mobilization costs, investment costs, loss rate of the Korea from “S(Spot price)”. By comparing put option price approved by Black-Shoulds model with the amount of Korea’s budget contribution to the USFK. we try to evaluate the efficiency of National Defense expenses and to lay out a logical basis for negotiation with the United States.
As a result, the interval of the strategic value is between 900 billion to 3.9trillion won in case of automatic intervention of US reinforcements, allowing Korea’s payments of 812billion and 836 billion won toward the USFK in 2011 and 2012 to be theoretically fairly valued as a Real Option price. The research can be lack of the reality because of the wide range of results, but we are able to get a more precise value by war scenario being kept secret. Considering the rate of change in Gross Domestic Product(GDP) after the wartime, the fair price of Put Option has been exponentially higher the sooner the US forces are augmented.
Though there have been numerous studies on what would be the fair amount of the defense cost sharing in economical perspective, none of them yet succeeded in satisfying the palate of the United States. in other words, Most of the study was a lack of objectivity and rationality to appeal to the emotions or claims by simple comparison logic.This research endeavored to be rational by analysing the rate of change in GDP approached by the real option method and to be practical by reflecting the probability of damage according to the war scenario. It is the first attempt in estimating the contribution scale to the budget using the real options approach and is expected to play the satisfactory role for the future SMA(Special Measure Agreement) as the bargaining chip.
The Effect of Benefits of smart donation contents on Donation Intention: Focusing on the Moderating Effect of Consumer Knowledge
Authors:   Asia-Europe Perspective Association, Kim Kyoung-Min , Park Seong-Yeon
Published: June 2018

The purpose of this research is to determine different donation intention by the benefits of smart donation contents and consumer knowledge. In this research, we identified the relationship between functional/psychological benefits of smart donation contents and donation intention, and also the moderator effect of consumer knowledge of donation participation and consumer knowledge of smart device utilization relatively.
Study 1 was conducted to examine how donation intention is differentiated by types of benefits of smart donation contents and consumer knowledge of donation participation. We conducted 2(benefits of smart donation contents: functional/psychological benefit)X2(consumer knowledge of donation participation: high/low) between subjects design. As the result, firstly, psychological benefits of smart donation contents have been shown more effective in increasing donation intention. Second, we find interaction effect between the benefits types of smart donation contents and consumer knowledge of donation participation on donation intention. Particularly, consumer who has low knowledge of donation participation has higher donation intention with psychological (vs. functional) benefits of smart donation contents. Thirdly, consumer who has high knowledge of donation participation has no significant difference on donation intention between benefits type of smart donation contents.
Study 2 was formed to identify how types of smart donation contents and consumer knowledge of smart device utilization differentiate donation intention. We conducted 2 (benefits of smart donation contents: functional/psychological benefit)X2(consumer knowledge of smart device utilization: high/ low) between subjects design. And as the result, firstly, there was no difference between donation intention affected by functional benefits and the one influenced by psychological benefits. Secondly, we did not find any difference of donation intention between the two types of benefits depending on consumer knowledge of smart device utilization (either high or low). Additionally functional benefits were found more effective when the consumer knowledge of smart device utilization is low, rather thann high.
Conclusively this research has theoretical and managerial implications. Differently from previous researches, this paper regarded smart donation contents as the object of marketing; also applied and studied ‘benefit’, one of many important marketing concepts, focusing on consumenr who use smart donation contents. In terms if managerial implication, it suggests specific strategy of production, promotion, and advertising for smart donation contents by segmenting consumers based on their knowledge of donation participation and smart device utilization.
The Effects of Ethnic Identity on Psychological Well-being and Job Satisfaction among Myanmar and Vietnam Workers in Korea
Authors:   Asia-Europe Perspective Association, Cho Chang Kwon , Li Jinxi Michelle
Published: June 2018

The increased number of foreigners in Korea (now more than 1.8 million) has necessitated understanding, analyzing and interpreting the immigration issues in order to solve the foreign workers’ social problems. This paper aims to investigate how the behavior aspects of ethnic identity (using home-country media, maintaining religious traditions, hanging around with homeland people) influence psychological well-being and job satisfaction. In addition, the paper aims to provide practical guidelines for social welfare organizations and enterprises which support and recruit them. The sample of our respondents was 146 foreign workers (90 Myanmar workers and 56 Vietnamese workers) in Korea. We used SPSS 21.0 for statistical analysis.
The results are as follows: using home-country media and maintaining religious traditions significantly influence both psychological well-being and job satisfaction. Furthermore, psychological well-being was found to mediate the relationship between home-country media and job satisfaction as well as between religious traditions and job satisfaction.
This study highlighted and demonstrated the importance of maintaining heritage culture in Korean multicultural policies. Integration has been considered as the most desirable acculturation strategy, but Korean multicultural policies have predominantly emphasized the assimilation aspect of integration only and have neglected another dimension of integration, which is maintaining heritage culture. Therefore, multicultural policies in Korea should help foreigners maintain their own home culture as well as help them adjusted to Korean culture. To do this, Korean government and other relevant agencies such as social services need to help foreigners easily access to home country media, help them connect to the relevant religious groups to maintain their own religious tradition, and establish social or cyber communities for the members from their own home countries.
A Study on highly educated women’s Retirement and Career Interruption in their 30s
Authors:   Asia-Europe Perspective Association, Lee Seung-Hyun , Park Young-Il
Published: June 2018

This study focused on the problem that women with high education are retiring in their 30s. This paper analyzes women’s lived realities in the labor market using data from Statistics Korea and the Women Manager Panel Survey. The study analyzes various contexts surrounding women managers’ career interruption.
According to the results of the analysis in this study, childcare was the greatest burden above all else for Korean women managers, and this acted as a direct reason for their resignation from their places of employment. To the women managers, marriage and childbirth by themselves were no longer direct reasons for resignation. However, the lack of childcare continues to be a primary cause for resignation for these women, and this situation seems to have become worse in 2014 than in 2010, regardless of their children’s age. This shows that in spite of the government’s efforts to implement various childcare policies, difficulties of childcare as experienced by women managers have not improved.
Furthermore, companies continue to pressure women to resign in the name of restructuring and “voluntary” retirement. Combined with pressures within the women’s families in which family members demand the women to take on the bulk of childcare responsibilities, this caused many women managers to resign from companies semi-voluntarily or non-voluntarily. The proportion of such semi- or non-voluntary resignation sharply increased in 2014 compared to in 2010. Although the government has attempted to combat career interruption by facilitating work-family reconciliation for women, bringing awareness to the issue, and implementing policies to improve working conditions, the success of these programs still seem to be quite limited.
Lastly, about half of the retired women managers were dissatisfied with their lives in all three survey years. This is attributed to economic reasons, as well as feelings of being underutilized, and uncertainties about their future. Only an extremely small number of the women who responded to the surveys started businesses or found other work, and even for those who started their businesses, most of the businesses were unrelated to their previous careers, and those that found other work were engaged in low-quality jobs. Therefore, for those women who have recently resigned and are under the risk of long-term career interruption, finding employment related to their career path would be the most important means of staying relevant in the job market. Although the government has implemented employment support policies for career-interrupted women’s reentry into the job market, their effectiveness is yet to be seen.
Inventory Decision of a Supplier Facing a Boundedly Rational Retailer
Authors:   Asia-Europe Perspective Association, Kwak Jin Kyung
Published: June 2018

In this study, we investigate the supplier’s inventory decision when facing a boundedly rational retailer. Existing literatures mostly assumed perfect rationality of decision makers, but recent studies found out that optimal decisions are not made in most cases. Su (2008) explained the behavioral aspect of newsvendor decisions by bounded rationality. Bounded rationality leads to stochastic decisions – better decisions with higher probabilities – rather than optimal ones. In particular, that study found out that the order quantity of a boundedly rational newsvendor follows a truncated normal distribution when he or she faces uniform end-customer demands. Using such proposition, we search for the supplier’s production quantity when the supply chain has a single supplier and a single retailer who faces a newsvendor problem with bounded rationality. The supplier faces a newsvendor problem for the retailer’s stochastic order decisions. We analyze how the supplier’s quantity differs from that under the case of perfect rationality and what factors affect the supplier’s inventory decision. While the existing study (Su, 2008) focused on that behavioral order decisions are affected by bounded rationality, this study mainly analyzes how the boundedly rational retailer’s order behavior affects the supplier’s inventory decision in a supply chain. Under the specific computational setup in this study, we observe that the relative change in the supplier’s production quantity is increasing in the degree of bounded rationality of the retailer, the wholesale price, and the supplier expediting cost. The relative change in the supplier’s production quantity is decreasing in the maximum value of the end-customer demand, the retail price, the supplier production cost, and the salvage value. The degree of bounded rationality may be reflected by skill levels of decision makers in practice. The results of this study imply that the supplier should consider the retailer’s order behavior especially when the wholesale price or the supplier expediting cost is higher, when the demand is less variable, or when the retail price, the supplier production cost or the salvage value of the product is lower.
The impact of new business of material sales on the supply chain operations strategy of a manufacturing company
Authors:   Asia-Europe Perspective Association, Kim Hyun-jung , Kim Eun-gab
Published: June 2018

This paper considers a manufacturer with a two-station make-to-stock (MTS) and make-to-order (MTO) serial production system. The MTS facility processes a single type of raw material and provides these materials for the MTO facility. The facility in the second stage produces end items using the material from the order of firms. The materials processed by the MTS facility are either stocked for production in the second stage or consumed to satisfy exogenous demand from the material market. Revenues are generated in each stage by satisfying the material demands and the end item demands, respectively. The manufacturer can either accept or reject some of the exogenous material demands according to the status of the system and the rejected exogenous material demands incur no penalty. The orders of firms can be rejected with penalty. Holding costs are incurred for the materials and the end items in inventory at each stage. Demand processes and production times of the component and the end item are stochastic. The set of decision epochs in our model corresponds to the epochs of customer order and material demand arrivals, MTO production completion, and material process completion. At each decision epoch, the manufacturer determines whether or not to process materials. An the epochs corresponding to a customer order arrival or a material demand arrival, a decision must be made whether to accept or reject it. This paper studies a joint order admission, demand control, and material process rate control policy which maximizes the manufacturer’s profit. Using the Markov decision process model, we investigate the structural properties of the optimal policy using a numerical example. The numerical investigation indicates that the optimal policy can be defined by the monotone stitching curves. Specifically, the optimal policy will accept more customer orders as material inventory increases and accepts fewer material demands as the number of outstanding customer orders increases. Furthermore, it is more profitable to increase the material production rate as the number of outstanding customer orders increases. We also examine the impact of the material process rate control option on the manufacturer’s profit. The study confirms that the material processing policy with a controllable production rate has a great percentage improvement in the average profit over the one with a fixed production rate. The study also show that the performance improvement due to using the controllable production rate rather than the fixed one is more prominent for the cases with a lower MTO customer arrival rate, a lower unit MTO sales revenue, a lower MTO production rate, a lower unit material sales revenue or a lower material holding cost. It is also observed that the impact of the material demand rate on the performance difference between the policies with a controllable production rate and a fixed one can vary depending on the value of other parameters.
Preparation of Poly(l-lactic acid) Scaffolds by Thermally Induced Phase Separation: Role of Thermal History
Authors: Carrubba V. La , Brucato V.
Published: June 2018

Poly-L-Lactic Acid (PLLA) scaffolds for tissue engineering were prepared via thermally induced phase separation of a ternary system PLLA/dioxane/tetrahydrofurane. An extension to solution of a previously developed method for solidification from the melt was adopted, the technique being based on a Continuous Cooling Transformation (CCT) approach, consisting in recording the thermal history of rapidly cooled samples and analysing the resulting morphology. Different foams were produced by changing the thermal history, the dioxane to THF ratio (50/50, 70/30, 90/10 v/v) and the polymer concentration (2, 2.5, 4 ° wt) in the starting ternary solution. Pore size, porosity, melting and crystallization behavior were studied, together with a morphological and kinetic analysis of the foams produced. A large variety of morphologies was achieved, the largest pore size (20 μm) was achieved at the highest polymer concentration (4 ° wt) and the lowest dioxane concentration (50/50 dioxane/THF v/v), whereas the largest porosity (90 °) was attained at the highest dioxane concentration (90/10). The average pore size is related to cooling rate, with a 1/3 power law exponent at low polymer concentrations and low dioxane content for thermal histories driven by low undercoolings. At high undercoolings, the growth of the demixed domains significantly departs from the diffusive-like regime.
Abnormal Behaviors in the Capillary Rheometry of Plastisol Formulations
Authors: Demay Y. , Abdesselam Y. , Castellani R. , Agassant J. F.
Published: June 2018

The rheology of plastisol formulations for flooring applications using knife-over-roll coating process is studied using both Couette and capillary rheometers. The behavior is similar in many aspects to the rheology of suspensions: Shear thinning behavior at low shear rate, then a Newtonian plateau at intermediate shear rates followed by a dilatancy peak. However several abnormal phenomena may be observed in capillary experiments. At very high shear rates, a second shear thinning behavior is observed which depends on the flow geometry. Due to the non-monotonous behavior of the plastisol viscosity, this is analysed using a dedicated numerical method. An apparent slip velocity has been determined. Otherwise capillary experiments point out the existence of important entrance pressure loss. These measures are interpreted using a modified Cogswell method as an important elongationnal viscosity, around hundred times the shear viscosity.

В структуре энергетического баланса Украины доля импорта энергоресурсов превышает собственную их добычу и производство, что ставит страну в серьезную зависимость от импорта, несмотря на то, что Украина имеет все возможности полностью обеспечить себя энергией. Для этого необходимо повышать уровень энергоэффективности и способствовать распространению использования экологически чистых технологий возобновляемой энергетики, в частности геотермальной энергетики. Геотермальная энергетика является устоявшейся и относительно зрелой формой коммерческого использования возобновляемых источников энергии. Важной характеристикой является фактор высокой нагрузки, что означает, что каждый МВт мощности производит значительно больше электроэнергии в течение года чем МВт ветра или солнечного потенциала.
