It is known that the cooling performance can be improved about 5~12% and the COP (Coefficient of Performance) can be improved about 10~15% when the IHX (Internal Heat Exchanger) was applied in a vehicle. Thus, the aim of this study was to observe the influence of the fins shape on the turbulence flow and turbulence kinetic energy gradient in IHX. All the applied parameters of the fin such as rotation angle, spacing ratio, height ratio and mass flow rate are changed. The governing equations for the flow motion simulation were applied to continuity equation and Navier-Stokes equation, and the turbulence model was applied by the Shear Stress Transport(SST) model, which has the advantage of turbulence simulation. As the rotation angles of the front and back fins were increased, the difference in the maximum turbulent kinetic energy gradient between fins was reduced. As the inlet flow mass increased, the turbulent kinetic energy difference between front and back fins were increased. The turbulence area tended to increase with increasing fin height ratio.

Introduction Business event are much important to economies of many destinations all over the world (Jago, Mair, Deery, & Bergin-Seers, 2008). As the term, “business events” is referred to be the MICE industry, encompassing with Meeting, Incentive, Conference/Convention, and Exhibition. The MICE industry underpins tourist visitation for many destinations. Such destinations have transferred into making substantial investments to provide the meeting/exhibition facilities and hotel needed for business events. Announced in the 5th of MICE and Luxury Travel Conference, India will generate 6.5 million outbound incentive tourists by 2030. Especially in these years, the number of MICE outbound tourists has been more than 1.5 million and the number of Luxury travel tourists has been up to 3.6 million (India Infoline Housing Finance Limited [IIFL], 2017). Research for one of the business events that remains in minority is incentives. Incentive travel, also known as IT, is defined as one of worldwide management tools which uses special travel experiences or recognizes participants who exceed the expectation on performance (Society of Incentive Travel Executives [SITE], 2013). According to the Incentive Federation, the number of U.S. business using non-cash rewards has raised dramatically from just 26% in 1996 to 84% of all U.S. businesses in 2016 (Incentive Federation, 2017). Incentive travel is becoming a field in which not only attractions and venues matter, but also the organization of parallel training activities and conferences around an incentive activity is possible (Celuch, 2014). The United States remains a primary destination for 82% of U.S. planners choosing U.S. in 2017 (Incentive Federation, 2017). Another popular incentive destination, Australia is also viewed as one of ideal destinations for incentive travel. Tourism Australia in 2008 indicated that 34% of incentive travelers is from China, 12% is from New Zealand, and 10% is from Japan. Taiwan has received over 10 million travelers from abroad in 2016. However, tourists from India traveling to Taiwan are only 33,000 passengers. According to report in 2016, International Congress & Conference Association [ICCA] announced that Taipei City has held 83 international conference and become top 10 destinations in Asia for The Best Stop to Meet Asia. However, is Taiwan a good incentive travel destination for India? Despite a limited amount of information on expenditure and the number of incentive programs, numerous gaps remain in our understanding of this sector of business events and cross-culture marketing, including how incentive travel organizers in India select their travel destination? And how this process may differ in source markets? This exploratory study aims to examine these site selection factors in the incentive travel context and identify any similarities and differences in how incentive travel is conceptualized, planned, and organized in India. Literature review Incentive Travel The incentive market has seldom been studied in great depth as an individual segmentation. Lewis (1983) carried out a concept that incentive travel represents a sizable market segment for hotel companies in many destination areas. Sheldon (1995) highlighted that travel was regarded as a motivating reward or incentive among America’s Fortune 100 companies, and that travel incentives were mostly used by companies in the service sector. Shinew and Backman (1995) identified the “trophy value” of travel incentives, and proposed that incentive travel allows long-lasting positive engagement in staffs’ job performance. Xiang and Formica (2007) used cognitive mapping to understand how incentive travel managers view the business environment, concluding with fast-pacing of incentive travel market, and global structural changes presenting challenges to incentive planners. Budget and cost, uniqueness of the destination, and availability of suitable facilities were thought to be factors influencing the choice of destination for incentive travel (Mair, 2005); however, this has not yet been demonstrated in empirical research. Convention Site Selection According to Crouch and Ritchie (1997) “the choice of destination can make or break the convention”. The first research by Fortin and Ritchie (1977) was considered the process undertaken by meeting planners when deciding on which location to choose for annual meeting or convention. The nine factors identified by Crouch and Ritchie (1997) are accessibility, local support, extra-conference opportunities, accommodation, meeting facilities, information, site environment and other criteria. Despite knowledge of the convention site selection process, very little research has considered how different types of meetings choose their destinations. In one of the few studies to consider the site selection process of incentive planners, Del Chiappa (2012) suggests a certain degree of “destination inaccessibility” could make incentive location being more extraordinary and exclusive. Mair, Jin, and Yoo (2016) indicated that incentive travel planners across three market- China, Australia, and America, shares similar perceptions on what characterizes incentive trips but differ slightly in the planning and operational phase pertinent to varying company characteristics and requirements. However, little is known about the cultural differences in incentive programs from one nation to the next. Methodology This research is an exploratory qualitative research, using in-depth interviews with incentive travel organizers, public relations professionals, company and staff who has participated in incentive travel to Taiwan and other Asian countries. Eight in-depth interviews (between 30 and 60 minutes) were carried out in India. The data collecting method is snowball sampling and 11 interviewees were invited by incentive organizers’ recommendations, while a list of qualified tour operators/specialists authorized by national tourism bureaus and organization (e.g., Ministry of Tourism Government of India or Travel Agents Association of India Active Member) are consulted as a sample frame, shown as table 1. Further, all interviewees were senior managers in their companies. For in-depth interviews, researcher has traveled to Mumbai, New Delhi and Jamshedpur in India between 12th and 26th Jan, 2018. Interviewees were asked to give some background on their incentive business. They were also asked to give information on how their incentive programs were structured and how they cooperate both with their incentive clients and with local suppliers of their incentive trips. Finally, they were asked in open-ended questions about their views on site selection, with eight site selection factors identified by Crouch and Ritchie (1997) and the outline designed by Mair, et al (2016). Findings This study explored site selection of incentive travel from the perspective of incentive planners, company, and participants. The finding suggests that the most popular incentive travel destination for Indian is Thailand with low expense and luxury hospitality. Most important part for choosing a destination is considering about food and beverage since there are a lot of vegetarian and chef should be familiar with Indian cuisine, for instance, foods in Singapore is more likely to be accepted by Indian. Both the operators and staffs from the company indicate that Indian travelers would like to have Indian cuisine and Bollywood show during the incentive trips, instead of local and cultural performance from the destination. Conference and accommodation facilities in China is well-prepared for MICE but expense is too high. Accessibility to Taiwan or to any countries won’t be a problem for incentive travel planners; nevertheless, there is still few direct flight from India to Taiwan which will influence the budget on overseas transportation. In addition, unfamiliarity with destination image of Taiwan reduces intention of visiting. However, since a new destination will be a motivator for encouraging employees to work hard, novelty destination for incentive trip is still important. One incentive travel planners suggest that enhancing the destination image by story-telling would help attracting Indian’s interests. Perceived risk will be reduces depending on local support (DMC). Incentive planners in India illustrate although decision maker is the representatives from companies, however, planners would give several packages of different countries, depending on budgets, basing on destination information from public relations professionals. It is obvious that public relations professionals and travel agencies are critical characters for site selection in India. F&B and budget are major considerations differing from other markets- China, Australia, and America. Conclusions This article interviewed incentive operators, public relations professionals, and company purchase incentive travel, and examined how incentive travel is conceptualized, planned, and organized in India. The study suggests government and bureau relating to MICE should get well prepared for cross-cultural incentive traveler, according to Indian culture. In addition, destination imagine promotion would be another effort for planners to select a site for incentive program. Since incentive planners in India are not familiar with Taiwan, local support/ DMC could look for public relations professionals from India as a connection, and put more focus on India as a potential market. Further study should explore the site selection in different countries, and marketing strategies. A limitation of this research that should be acknowledged is the small sample size. However, the initial conclusions from this research suggest that, while the site selection factors identified in other markets provide a useful place to start, incentive travel organizers do not rely on same factors. The findings from this project will provide a basis for future research in the area of incentive, and useful information for incentive planners/organizers in Taiwan and worldwide.

As information technology advanced, customers’ service consumption process heavily shifted to the online environment, particularly social media and mobile. A new topic, customer engagement, has emerged along with the fast advancement of social media. Customer engagement refers to a type of customer behavior that is beyond purchase such as spreading word-of-mouth, providing recommendations to family and friends, interacting with fellow customers, and writing online reviews (Bijmolt et al., 2010; Verhoef, Reinartz, & Krafft, 2010). This study introduces the Flow theory, which is especially important to understand consumers’ online experiences, with the intention to shed light on how to better engage consumers in the hospitality industry (Bilgihan, Okumus, Nusair, & Bujisic, 2014; Hoffman & Novak, 2009). The purpose of this study is to examine the antecedents of flow and further investigate its influence on positive attitude and continuance intention among restaurant social media users. This study specifically examines restaurant customers who use social media through their smart phones in searching information and sharing experiences with others. A self-administered questionnaire was developed and a Structure equational modeling (SEM) was employed to test the proposed hypotheses. Study results support the hypotheses, indicating the importance of creating flow to increase customer engagement. Academically, this study contributes to the limited body of literature on flow experience and customer engagement in the hospitality context. Additionally, it provides practical insights for hospitality marketers on how to gain competitive advantages by strategically managing customer engagement on social media marketing through flow.

An AVL research engine, type 520, is modified to adapt to the 3.5L four-valve SI engine. With these given engine configurations, a test rig is constructed which allows easy changing of the different pistons and engine heads with a motoring capacity up to 3500 rpm. Nearly complete optical access to the inside of the cylinder is obtained by installing a transparent quartz cylinder on an AVL single cylinder engine. To avoid lubrication and to minimize scratches in the quartz cylinder the piston rings are made of Rulon-LD. With this experimental engine, researches for the in-cylinder flow characteristics by changing the induction system have been carried out using the laser based flow diagnostic techniques. In accordance with the previous result, it is evident that larger sized particles would be required in order to observe the flow characteristics of interest. The flow visualization taken with microballoon particles shows significant improvement. This provide detailed information.

Two climate change scenarios, the RCP (Representative Concentration Pathways) 4.5 and the RCP 8.5 in the fifth Assessment Report (AR5) by Intergovernmental Panel on Climate Change (IPCC), were applied in the Yocheon basin area using the SWAT (Soil and Water Assessment Tool) model to estimate changes in flow rates and pollutant loadings in the future. Field stream flow rate data in Songdong station and water quality data in Yocheon-1 station between 2013~2015 were used for model calibration. While R2 value of flow rate calibration was 0.85 and R2 value of water qualities were in the 0.12~0.43 range. The total study period was divided into 4 sub periods as 2030s (2016~2040), 2050s (2041~2070) and 2080s (2071~2100). The predicted results of flow rates and water quality concentrations were compared with results in calibrated periods, 2015s (2013~2015). In both RCP scenarios, flow rate and TSS (Total Suspended Solid) loadings were estimated to be in increasing trend while TN (Total Nitrogen) and TP (Total Phosphorus) loadings showed decreasing patterns. Also, flow rates and pollutant loadings showed larger differences between the maximum and the minimum values in RCP 4.5 than RCP 8.5 scenarios indicating more severe effect of drought and flood, respectively. Dependent on simulation period and rainfall periods in a year, flow rate, TSS, TN and TP showed different trends in each scenario. This emphasizes importance of considerations on time and space when analyzing climate change impacts of each variable under various scenarios.

Using network betweenness centrality we attempt to analyze the characteristics of Seoul metropolitan subway lines. Betweenness centrality highlights the importance of a node as a transfer point between any pairs of nodes. This ‘transfer’ characteristic is obviously of paramount importance in transit systems. For betweenness centrality, both traditional betweenness centrality measure and weighted betweenness centrality measure which uses monthly passenger flow amount between two stations are used. By comparing traditional and weighted betweenness centrality measures of lines characteristics of passenger flow can be identified. We also investigated factors which affect betweenness centrality. It is the number of passenger who get on or get off that significantly affects betweenness centrality measures. Through correlation analysis of the number of passenger and betweenness centrality, it is found out that Seoul metropolitan subway system is well designed in terms of regional distribution of population. Four measures are proposed which represent the passenger flow characteristics. It is shown they do not follow Power-law distribution, which means passenger flow is relatively evenly distributed among stations. It has been shown that the passenger flow characteristics of subway networks in other foreign cities such as Beijing, Boston and San Franciso do follow power-law distribution, that is, pretty much biased passenger flow traffic characteristics. In this study we have also tried to answer why passenger traffic flow of Seoul metropolitan subway network is more homogeneous compared to that of Beijing.

PURPOSES : In this study, analyze the characteristics of IOC indicator 'threshold' which is needed when evaluating the traffic signal operation status with ESPRESSO in various grade road traffic environment of Seoul metropolitan city and derive suggested value to use in field practice. METHODS : Using the computerized database program (Postgresql), we extracted data with regional characteristics (Arterial, Collector road) and temporal characteristics (peak hour, non-peak hour). Analysis of variance and Duncan's validation were performed using statistical analysis program (SPSS) to confirm whether the extracted data contains statistical significance. RESULTS: The analysis period of the main and secondary arterial roads was confirmed to be suitable from 14 days to 60 days. For the arterial, it is suggested to use 20 km/h as the critical speed for PM peak hour and weekly non peak hour. It is suggested to use 25 km/h as the critical speed for AM peak hour and night non peak hour. As for the collector road, it is suggested to use 20 km/h as the critical speed for PM peak hour and weekly non peak hour. It is suggested to use 30 km/h as the critical speed for AM peak hour and night non peak hour. CONCLUSIONS : It is meaningful from a methodological point of view that it is possible to make a reasonable comparative analysis on the signal intersection pre-post analysis when the signal operation DB is renewed by breaking the existing traffic signal operation evaluation method.

The Korean Ministry of Education (MOE) required cash flow statements, instead of fund statements, as a component of the financial statements of the Industry-Academic Cooperation Foundations (IACF) when it revised IACF accounting rules in 2012. While the fund statements were aligned its accounts to the operating statements’ accounts level, the newly adopted cash flow statements’ accounts retreated to two levels higher than those of the operating statements. It may be resulted from the consideration that IACFs’ burden of preparing cash flow statements especially in direct method. To help IACFs prepare the cash flow statements, MOE's guidance on IACF accounting rules introduced cash flow statement preparation method and presented a practical example, but it did not check whether the accounts of the cash flow statement were reconciled to the accounts of corresponding balance sheet and operating statement. That means that the guidance still lacks how to assure it was accurately prepared. Our study proposed cash flow statement preparation using reconciliation method which reconciles cash flow statement accounts’ amounts to balance sheet and operating statement accounts’ amounts with integrity checking and also provided a practical example by using the same case in MOE’s guidance on IACF accounting rules to help IACF accounting personnel to prepare a cash flow statement efficiently.

이 논문은 상류로부터 유입되는 토석을 도시생활권의 목표공간까지 유도하기 위한 유도둑의 도류 각 변화에 따른 토석류 퇴적형태 및 최대 충격파고의 변화를 파악할 목적으로 실시한 실내 모형실험 결과를 정리한 것이다. 실험결과, 유도둑이 상류에서 발생한 토석류를 목표로 하는 방향으로 유도하는 데 매우 효과적인 것으로 파악되었다. 또한 유도둑의 도류각이 30° 이상일 경우 토석류의 유심이 유도둑과 충돌하여 에너지가 손실됨으로써 토석의 퇴적이 발생하였다. 특히, 유도둑의 도류각이 0° 에서 30°까지 증가할수록 퇴적토석의 폭이 점차 좁아지고 두꺼워지는 것으로 나타났으나, 유도둑의 도류각이 45°인 경우에는 지나친 통수단면의 감소를 초래하여 상류구간에서 토석퇴적의 집중도가 높아 토석류가 유도둑을 월류하여 범람할 가능성이 높은 것으로 판단되었다. 한편, 유도둑의 도류각이 30° 이하일 경우 토석류의 최대 충격파고는 유심선과 유도둑이 만나는 지점에서 형성되고, 이 지점을 기준으로 실험 중에 상류구간에서 최대의 토석퇴적이 형성되며, 실험 종료 후 하류구간에서 토석 퇴적의 피크가 낮게 형성되었다. 다만, 유도둑의 도류각이 45°인 경우에는 최대 충격파고가 실험 중 최대 토석퇴적이 발생한 지점에서 매우 높게 형성되는 것으로 나타나 토석이 집중적으로 퇴적되어 후속류 등에 의한 토석의 유도에 효과적이지 못할 것으로 판단된다. 비록 이번 연구를 통하여 유도 둑이 토석류 처리에 유효하다는 점은 확인되었지만, 토석류의 충격파고에 따른 유도둑의 적정 유효고 설정에 관한 수리학적 연구가 추후 필요하며, 나아가 이러한 설계기준을 근거로 현지적용에 대한 시공기준을 정립하여야 할 것이다.
