Big Data is now seen as a major asset in the company's competitiveness, its influence in the future is expected to grow. Companies that recognize the importance are already actively engaged with Big Data in product development and marketing, which are increasingly applied across sectors of society, including politics, sports. However, lack of knowledge of the system implementation and high costs are still a big obstacles to the introduction of Big Data and systems. It is an objective in this study to build a Big Data system, which is based on open source Hadoop and Hive among Big Data systems, utilizing POS sales data of small and medium-sized offline markets. This approach of convergence is expected to improve existing sales systems that have been simply focusing on profit and loss analysis. It will also be able to use it as the basis for the decisions of the executive to enable prediction of the consumption patterns of customer preference and demand in advance.

This research is to analyze the force on landing 3 Type of Halfpipe Curves(Ellipse, Circle, Brachistochrone) based on the mechanical calculation of normal force on a sloping surface. Jumping off a platform on a bard horizontal surface, the flexing of the legs, the softness of the snow, the angle of the landing surface, initial velocity and the forward motion of the snowboarder can contribute to reducing the force on landing. But halfpipe is significantly determined by the curvature of surface. It is definitely verified that the Brachistochrone curve is more safety than others. However currently using the Ellipse curve is mostly safe too. If we consider the efficiency of construction, we can easily think there is no use of another curves except normal ellipse curved halfpipe. It would better that geometrically verity curved halfpipe should be designed for improving fluent skills to snowboarders. This methode of research can be a model of scientifical research on sports safety how can sportsman reduce critical injury by designing optimal halfpipe facilities and manual.

The purposes of the present study were to investigate the impact of a apparel brand and an ingredient brand on evaluation(perceived quality, favorable attitude, purchase intention) of apparel products, and to examine the differences in evaluations toward apparel products allied with ingredient brands between groups divided by product knowledge and leisure involvement. The subjects were 235 men and women aged 20 to 40. Two-by-two factorial design were employed. A series of ANOVA were used to determine if significant differences existed in evaluations of apparel products. There was a significant interaction effect of an apparel brand and an ingredient brand on evaluations of apparel products. Empirical results showed that ingredient brands would improve the consumers' perceived quality, favorable attitude and purchase intention toward apparel products. In addition, the results indicated that the respondents that had high leisure involvement and high product knowledge were more likely to evaluate apparel products based on the ingredient brand of the products. However, the respondents that had low leisure involvement and product knowledge were more likely to evaluate apparel products based on the host brand of the products.

This research sought to analyze the characteristics of breast movement at the treadmill activity levels. It also examined the effect of wearing a sports bra in reducing breast displacement. The subjects for the data collection were females in their 20s (n=2) with C-cup size breast. The experimental conditions were three different moving speeds (4 km/h, jogging: 7 km/h, and sprinting: 10 km/h) and two types of sports bras. Three dimensional breast displacement was measured. The displacement of the right nipple point was measured with a 3D motion analyzer. The results show that the breasts were greatly displaced from the walking speed (4 km/h) when subjects did not wear any bra. Whereas their breast displacement distance decreased remarkably when they wore sports bras. The nipple point moved 42~44 mm in the vertical direction at walking speed with naked condition. But it was reduced by 80% after wearing sports bras. When subjects running (7 km/h, 10 km/h) without any bra, the nipple point moved 122~141 mm. However it was reduced by 60~70% when they wore sports bras. The apartment time (time delay) between at the highest point of the upper body and the nipple was 0.25 seconds at the running speeds (7 km/h, 10 km/h) without wearing any bra. After wearing sports bras, the time delay was cut to 0.06~0.12 seconds. These results implies that without wearing any bra the skin surrounding the breasts might be seriously pulled at running activity. The functional sports bra suppress breast movement. It might prevent the sagging of breasts by preventing the damage of the Cooper's ligaments.

Economic impact analyses have not been widely conducted in archives. This article reports on a two parallel surveys in the US and Canada to assess the economic impact of government archives (state, provincial, territorial, county, and municipal). The surveys utilize indirect measures of economic impact. Responses from 2,534 people in 66 archives were analyzed. Findings indicate that archives were the primary reason that respondents visited an area and that visitors exhibit specific patterns of visiting the archives in conjunction with other cultural organizations in an area. Furthermore, while many respondents used local eateries, fewer rented lodgings or spent money on theater or sporting events. As a result, the archives participating in this survey did have a modest impact on local economies. The article concludes by discussing three major questions about the evaluation of the economic impact of archives which were raised by the findings: 1) Are indirect measures the most appropriate means of assessing economic impact in archives or should archives employ direct measures as used by public libraries? 2) How should government archives formulate their value proposition and should those value propositions focus on other aspects of archives' impact, such as the social impact, to demonstrate archives' important role in society? and 3) Since visitors exhibited distinct visitation patterns, should archives work more with these other aligned organizations and work on larger forms of collective impact that benefit the entire cultural heritage sector in an area?

This study suggests a plan for revitalizing return-to-farming / fishing villages through the marine leisure industry by analyzing the practical problems faced by young and older adults who have returned to the marine leisure field. A case study was conducted to identify the problems faced by those returning to marine leisure, and to determine the measures for revitalizing return-to-farming / fishing villages. Interview participants were those returning to marine leisure and experts in related fields. The problems identified include the exclusive culture of fishing villages, difficulty in raising initial investment funds, and lack of marine leisure education programs for return-to-farming / fishing villages. The proposals to solve these problems and revitalize return-to-farming / fishing villages through the marine leisure industry include the introduction of an incentive system to mitigate barriers to entry; establishment of a matching system; use of idle land in fishing villages to promote return-to-farming / fishing villages; introduction of a consignment management system after the pre-investment of the fishing villages; and establishment of an education program, including in the fisheries field, and infrastructure for return-to-farming / fishing villages for marine leisure.
