In this research, Collectivism's influence on Singaporean employee's volunteerism in Multinational Enterprise (MNE) was investigated with an individual empathy mediating. Most research on Hofstede's cultural dimensions were examined at national levels. However, in this study, Yoo's Cultural value Scale (CVSCALE) was used to analyze collectivistic tendencies at individual levels and its influence on volunteerism. A total of 200 self-administering online surveys was distributed to MNE employees in Singapore for three weeks period. 180 usable surveys were collected and analyzed with SPSS 21.0. Research outcomes indicated collectivism positively influenced volunteerism in Singaporeans with empathy as possible antecedent of volunteerism. In conclusion and application, the significance of this research lies in indicating collectivism's positive impact on volunteerism and empathy as possible antecedents of volunteerism in Singaporeans even though Singapore has exhibited stronger individualism and often defined as one of the most westernized country in the Asian continent. Also findings suggest further developing emotional education to increase both individual and group level performance.

The purpose of this study was to provide directions to help enter and expand long-distance routes by analyzing the characteristics of AirAsia X's network construction with Malaysia Airlines. To this end, long-distance route data was extracted from the OAG Schedule Analyzer and the network was analyzed on a two-period basis using SNA. Since AirAsia X's entry into long-range routes, Malaysia Airlines has steadily reduced its routes across the entire region. On the other hand, it is analyzed that AirAsia X is building an expanded network by increasing its network in Northeast Asia instead of ultra-long range routes. Studies have shown that LCCs also have potential growth in the long-distance route market of less than 7,000 km. The results of this study may help LCC establish a long-distance market entry and network deployment strategy.

This paper aims to analyze the causal relationship between exports and regional economic growth based on the provincial data over the period from 1952 to 2004. To reflect the regional and chronical characteristics, this paper divides China into three regions; Eastern, Central and Western regions, and also the whole period into two sub-periods; before and after 1979 when the Open-door policy(ODP) was initiated and applies Granger causality analysis. The Granger causality tests showed that exports Granger cause economic growth in the Eastern region, but not in the Central and Western regions, as a whole. When the period is divided, in the Eastern region, causal relation between the two variables was not found before the Open-door policy. For the second period, however it turns out that exports cause the region's economic growth. This result is consent with the fact that the region has been a main beneficiary of the policy. For the Central region, the tests showed no causality in the pre-ODP period, but significant bidirectional causality in the post-ODP period. Meanwhile, in the Western region, exports turned out causing economic growth significantly before the ODP, while economic growth appeared to causing trade after the ODP.

This study investigates factors to disturb the e-Learning persistence of adult learners based on a case study of Cyber University students located in Seoul Korea. Main findings of our research show that economic burden, shortage of studying hours, digital literacy problem, perceived isolation, inefficient interaction between lecturer and student, and support of family are primary factors to influence the persistence of online education in a Cyber university. From our case study, we recommend to improve the scholarship system, and supplement the offline special lectures at weekends in order to alleviate perceived isolation. A novelty of this paper is that economic burden is highlighted to influence the persistence of adult learners.

The purpose of this paper is to examine how visuospatial ability affects the situation awareness for older drivers while driving. For this study, the Rey-Osterrith Complex Figure (ROCF) was used to measure the visuospatial ability of older drivers. The ROCF is used to measure visuospatial construct and memory abilities, and Real-Time Probes were used to measure the situation awareness with UC-win/Road simulation. Sixty drivers participated in this research (N = 30 older drivers, median = 70 years old and N = 30 younger drivers, median = 27 years old). Based on the results of this analysis, a repeated measure ANOVA was used to analyze the effect on each level of situation awareness related to visuospatial ability in driving. The results indicate that the visuospatial ability of older drivers serves as a crucial factor in determining the potential for older drivers to safely continue to drive. The results also imply the necessity of ROCF development to support and improve the visuospatial ability of older drivers.

In this paper, we propose that investigating the relationship between the dynamic capacity and the technological innovation performance of firms. Based on the previous research, we divide the dynamic capacity into the adaptive capacity, absorption capacity, and productive capacity. Among the 3,400 companies responding to the technical statistics of SMEs in 2011, we performed multiple regression analysis with 2,807 except service industries. As a result, the absorptive capacity and productive capacity have a positive effect on the technological innovation performance at the 99% level, whereas the adaptive capacity has a negative effect on the technological innovation performance at the 95% level. The implications of this study are as follows. First, in order to improve the performance of technological innovation, it is important to strengthen the absorption capacity and productive capacity of companies. Absorption capacity shows that it is important to secure sufficient R & D manpower and R & D cost to utilize internal knowledge as well as to bring outside knowledge into the capacity to assimilate and utilize external knowledge. Second, the ability to commercialize a product is a capability to commercialize a technology that has succeeded in development, showing that the technology development organization must have the capability of post-development commercialization as well as technology development. Finally it shows the negative effect on adaptation capacity and innovation performance. Companies actively utilize external sources of information in order to respond to and adapt to the rapidly changing business environment. However, the results of this study show that a strategic approach is needed to use external sources of information and technology development resources. Especially as the use of external information resources and technology development resources increases.

The aim of this study is to investigate the effects of income inequality caused by capital and wage incomes under globalized economic system in Korea. Empirical evidences which are obtained by cointegration methodology reveal that the effects resulted from capital and wage incomes to income inequality are alternative between short-run and long-run. And, the wage income has stronger impact on income inequality than the capital income. This might be occured as a result of that inbound foreign capital seems not to contribute to economic activity in real sector. It also has to be mentioned that the income inequality is negatively influenced by international trade in the short run and in the long run as well. To this end, it would be concluded that well-organized distribution system for wage income should be established, accordingly. And, forward and backward linkages in exporting industry have to be re-evaluated in order to improve income inequality in Korea.

Industrial groups (representing the polluters) and environmental non-governmental organizations (representing the victims) respond differently to various environmental policy instruments. As the affected group's power is large either politically or economically, it is unlikely that a single instrument will be actually selected despite being effective or efficient because of the high political costs associated with it. In this paper, we focus on the political role that energy subsidies play in creating a compromise between energy consuming polluters and victims of pollution. The use of a Dolbear (1967)'s triangle Edgeworth box model makes it possible to examine how policy selection affects the income distribution and welfare levels of two groups. The effects of a single policy instrument of either direct regulation or tax are compared with those of a policy mix that includes energy subsidies. We found that the addition of energy subsidies would increase the chance of compromise between polluters and victims.

The use of computational fluid dynamics (CFD) is becoming an increasingly popular means to model wind flows in and around buildings. The first published application of CFD to both indoor and outdoor building airflows was in the 1970's. Since then, CFD usage has expanded to include different aspects of building design. Wind tunnel testing (WTT) on buildings for wind loads goes back as far as 1908. Gustave Eiffel built a pair of wind tunnels in 1908 and 1912. Using these he published wind loads on an aircraft hangar in 1919 as cited in Hoerner (1965 - page 74). The second of these wind tunnels is still in use today for tests including building design ($Damljanovi{\acute{c}}$, 2012). The Empire State Building was tested in 1933 in smooth flow - see Baskaran (1993). The World Trade Center Twin Towers in New York City were wind tunnel tested in the mid-sixties for both wind loads, at Colorado State University (CSU) and the [US] National Physical Laboratory (NPL), as well as pedestrian level winds (PLW) at the University of Western Ontario (UWO) - Baskaran (1993). Since then, the understanding of the planetary boundary layer, recognition of the structures of turbulent wakes, instrumentation, methodologies and analysis have been continuously refined. There is a drive to replace WTT with computational methods, with the rationale that CFD is quicker, less expensive and gives more information and control to the architects. However, there is little information available to building owners and architects on the limitations of CFD for flows around buildings and communities. Hence building owners, developers, engineers and architects are not aware of the risks they incur by using CFD for different studies, traditionally conducted using wind tunnels. This paper will explain what needs to happen for CFD to replace wind tunnels. Ultimately, we anticipate the reader will come to the same conclusion that we have drawn: both WTT and CFD will continue to play important roles in building and infrastructure design. The most pressing challenge for the design and engineering community is to understand the strengths and limitations of each tool so that they can leverage and exploit the benefits that each offers while adhering to our moral and professional obligation to hold paramount the safety, health, and welfare of the public.
