게임 고객의 충성도 혹은 재구매 의도를 경영학의 고객 충성도 이론을 적용해 보는 거시적 분석이 있었지만 게임 시스템이 복잡해지면서 흥행에 성공한 특정 게임의 장기 충성 사용자의 행동 패턴을 분석함으로써 실증적으로 그 게임에 대한 애착과 성공의 원인을 알아보는 것도 의미가 있다. 본 논문에서는 2012년 출시되어 초창기에 흥행에 큰 성공을 거두고 지금도 점유율 10위권에 자리하고 있는 판타지 퓨전 무협 MMORPG 블레이드 앤 소울의 3년 이상 장기충성 사용자들의 행동 패턴이 1년 미만의 캐주얼 집단, 플레이 경력 1~3년 사이의 집단과 어떻게 다른 지 222명의 피험자에 대해 설문을 통해 살펴보았다. 그 결과 그 게임의 강점으로 알려진 던전 활동, 비무, 전장의 전투 방식과 내용보다는 그 게임 커뮤니티에의 끈끈한 애착이 더 중요했다. 심지어 전투 밸런스의 만족도는 5점 척도에서 모든 그룹이 1점대를 기록하기도 하고 초심자와 장기사용자가 1~3년 사용자보다 전투 레벨이 높은 U-커브를 나타내기도 했다. 이에 다시 148명의 장기 사용자의 설문 분석을 통해 커뮤니티 내 인간관계 형성 요인과 패턴을 조사하였다.

Use of composite steel construction with precast hollow core slabs is now popular in the UK, but the present knowledge in shear capacity of the headed shear studs for this type of composite construction is very limited. Currently, all the information is based on the results obtained from experimental push-off tests. A finite element model to simulate the behaviour of headed stud shear connection in composite beam with precast hollow core slabs is described. The model is based on finite element method and takes into account the linear and non-linear behaviour of all the materials. The model has been validated against the test results, for which the accuracy of the model used is demonstrated. Parametric studies showing the effect of the change in transverse gap size, transverse reinforcement diameter and in-situ concrete strength on the shear connection capacity are presented.

The purpose of this study is to provide the technical information of the stability change and behaviour characteristics in case upward direction of soil nailing is installed. Generally, the soil nailing which installed in case of vertical excavation or for the purpose of the slope stability is installed between 5 to 15 degree of downward direction. The downward direction of the soil nailing method has lots of advantages such as the increase of the stability, the convenience of the grout compared to upward direction of soil nailing. Even though the upward direction of the soil nailing has the disadvantages in terms of the stability and the grout construction, horizontal displacement tends to be decreased.

As the social value gradually increases, the company's social responsibilities are granted and there are a growing number of requirements for a public value to economic value for the company. The cause marketing which has become widely known, it allows us to realize these values and in dictionary meaning, enterprises justification combines with marketing strategically, and is also illustrated as 'Cause Related Marketing.' For specific action plan, it is a marketing by connecting the selling of the product and donation to work out together to improve environment, public health, and poverty. This study examines how the cause marketing impact on the consumer's purchasing behaviour and purchasing intention and to find out whether there is an interrelationship. As a result, it turned out that cause marketing effect on purchasing attitudes and also the purchasing behaviour impact on the purchasing intention. Furthermore, the cause marketing influence on purchasing intention. As the idea of consumption gradually changes from the product consumption to value-based consumption as the time flows, the result of this research drew out the meaningful contents.

This paper presents and efficient algorithm for the loss minimization by automatic sectionalizing switch operation in distribution systems. Ant colony algorithm is multi-agent system in which the behaviour of each single agent, called artificial ant, is inspired by the behaviour of real ants. Ant colony algorithm is suitable for combinatiorial optimization problem as network reconfiguration because it use the long term memory, called pheromone, and heuristic information with the property of the problem. The proposed methodology with some adoptions have been applied to improve the computation time and convergence property. Numerical examples demonstrate the validity and effectiveness of the proposed methodology using a KEPCO's distribution system.

The seismic safety of concrete dams is one of the important problems in the engineering due to the vast socio-economic disasters which may be caused by collapse of these infrastructures. The accuracy of the risk evaluation associated with these existing dams as well as the efficient design of future dams is highly dependent on a proper understanding of their behaviour due to earthquakes. This paper develops an anisotropic damage model for arch dam under strong earthquakes. The modified Drucker-Prager criterion is adopted as the failure criteria of the dynamic damage evolution of concrete. Some process fields and other necessary information for the safety evaluation are obtained. The numerical results show that the seismic behaviour of concrete dams can be satisfactorily predicted.

A study on collision analysis of TGV-K using a 2-dimensional model is described to evaluate its crashworthiness. Two-dimensional analysis gives good information on overriding behaviour and impact forces applied to interconnecting devices such as side buffers, ball & socket joints, hooks, pins, and fingers. Since the headstock of TGV-K is not designed in a crashworthy point of view, its conceptual design fur KHST(Korean High Speed Train), under development, is suggested to improve crashworthiness. The suggested design, which adopts an energy absorber and a crashworthy headstock, is compared with the conventional headstock on dynamic behaviour to the vertical direction under the accident scenario of SNCF (collision at 110km/h against a movable rigid mass of 15 ton). It is concluded that the design modification make little difference in vertical motion. To evaluate validation of the 2-dimensional model, the results fur longitudinal motion is compared with those of 1-dimemsional one. It is found that the two results are in good agreements.

This research aims to analyse the practices adopted by social media users in the Kingdom of Saudi Arabia (KSA), specifically users of Facebook and Snapchat. To collect data from participants, a questionnaire was used, generating 915 responses. The analysis of the data shows a clear preference for Snapchat over Facebook in the KSA, where 89% of the participants have accounts on Snapchat compared to 66% of them with accounts on Facebook. Moreover, the preference for Snapchat over Facebook has been clearly shown in the daily usage of participants, where 83% of those with Snapchat accounts can be described as very active users. They have accessed their Snapchat accounts at least once a day compared to only 15% of Facebook users. Different reasons were provided by the participants explaining the practices they adopted. We believe that such research could help social media applications' designers and policy makers to understand the behaviour of users in the KSA when using social media applications and the rationale behind their behaviour and preferences. This understanding could help improve the performance of current applications and new ones.

In this study, we analyzed the factors that affect public awareness campaigns on social media platforms and developed an integrated model for measuring the persuasiveness of environmental social media campaigns. A survey questionnaire was created and distributed on Facebook with the goal of reaching individuals in their 20s and 40s in Vietnam, and 395 valid replies were gathered. The findings showed that the STOPS was reconfirmed as a suitable theoretical framework for analyzing the public's behaviour intention to conduct information related to the issue of fine dust, especially on social media. Furthermore, it also showed that social media efficacy has a moderating effect on the relationship between public's situational recognition and informational behaviour intention. This suggested that through social media platforms, personal characteristics play a vital part in developing effective environmental campaigns. Implications for both theory and practice were discussed.

In this paper, we analyze the behaviour of flows near closed sets with compact boundary which contains no semi-orbits. Also, we give a condition that a closed invariant set is to be asymptotically stable.
