The purpose of this study is to investigate the differences in fashion shopping orientation and perceived value according to the level of use of mobile fashion shopping. Furthermore, the effect of fashion shopping orientation on perceived value was analyzed. To estimate the level of use of mobile fashion shopping, respondents were classified into four different groups in terms of their frequency of buying fashion products and the period for which they had bought fashion products. The survey was limited to adults aged 20-40 years who had purchased fashion products in a mobile shopping mall. The questionnaire was carried out from April 15, 2015 to April 22, 2015 and 430 sets of useful response data were analyzed using SPSS 17.0. The results of this study were as follows: First, fashion shopping orientation for mobile shopping consumers was divided into four factors as follows: convenience/ economic shopping, ostentation/trend shopping, enjoyment shopping, and impulse shopping. Second, there was a significant difference in all the fashion shopping orientation factors except for convenience/economic shopping according to each classified group: short/few, long/few, short/many, and long/many. In addition, there was a significant difference in perceived value according to each group. Third, all the fashion shopping orientation factors except for impulse shopping had a significant influence on perceived value. Fourth, fashion shopping orientation factors had a slightly significant influence on the perceived value according to each group.

본 연구에서는 해상에서 선박의 외측 표면 검사를 위한 모바일 로봇의 개발에 대해 언급하였다. 해상에서 선체 측면에 대한 검사를 육안으로 진행하기 어려우며 이러한 검사를 효과적으로 수행하기 위해 모바일 로봇은 선체 측면에 부착되어 주행할 수 있는 기능을 갖추어야 한다. 이를 위해 선체 측면과의 부착력을 발생시키기 위해 영구 자석 모듈을 도입하였고, 곡면 주행 시 자기력의 변화를 최소화하는 구조로 설계를 하였다. 이러한 설계를 바탕으로 4개의 네오디움 자석, 4개의 구동바퀴, 영상 획득 모듈로 구성되는 모바일 로봇을 제작하였다. 제작된 로봇에 대해 선체와의 부착력을 확인하기 위한 하중 실험을 실시하였고, 주행이후 정지 시 측면 미끄럼 실험과 주행 속도 측정 실험을 실시하였다. 실험 결과 13 [Kgf]까지 선체와의 부착력을 유지할 수 있었고, 미끄러짐이 없는 하중은 8 [Kgf]까지였다. 주행 실험에서는 6.5 [A]의 전류에 대해 0.82 [m/s]의 속도로 주행할 수 있는 것을 확인하였다. 선박의 표면 검사를 위해 개발한 모바일 로봇의 특성 실험을 통해 로봇의 유용성을 확인할 수 있었다.

According to the statistics, occupational fatal injuries by mobile cranes were about 12 per year in whole industrial. Mobile cranes are widely used in various parts of industries to improve the efficiency of the work. However considerable number of fatal injuries happen each year during the operation of the machines. In this study, the current regulations to be adequate in industrial site have to be renew in order to prevent the fatal injuries by mobile cranes. Fatal injury analyses were conducted with several accident cases by the mobile cranes. For each accident, the causes of the injuries were examined and proper safety measures were proposed. In this study, the mobile crane showed a high fatality rate in industrial accidents and no detailed cause analysis of fatal accidents was conducted in terms of unsafe acts or conditions. This study proposed a revision of the standard guideline as an accident prevention measures through in-depth analysis of fatal accidents. First, among the mainly five machines caused the accidents, mobile crane was higher for the second showed 0.6% for number of fatalities compared to number of mobil cranes and for the third showed 11% for number of fatalities compared to number of injuries. Second, main cause of cognitive engineering agenda was visibility, responsibility, affordance. As the measures to prevent accidents before starting operation, alternative revision for the fool proof including visibility, responsibility, affordance etc. for the fool proof measures was proposed. Third, alternative revision as cognitive accident prevention for the fail safe measures was proposed.

The serviceability design of the high-rise building is affected by the wind response vibration such as the acceleration, at this time it is important to calculate the natural frequency correctly. Since the suggestion equation of the natural frequency being used in the design phase is not the regression equation obtained from the vibration measurement of the high-rise building, the verification to use for the serviceability design of the high-rise building is necessary. This thesis conducted an ambient vibration measuring on the high-rise building through the mobile-phone application to calculate the natural frequency and suggested a natural frequency approximate expression following the building's height, and compared with the domestic/foreign standard and the result of the eigen-value analysis.

제품이나 서비스에서 사용자가 예상하지 못한 의외성을 제공할 때 사용자는 만족을 넘어 감동할 수 있으며, 최근 몇몇 애플리케이션이나 웹서비스는 이러한 의외성을 제공하고 있다. 그러나 의외성 자체는 오히려 사용 용이성을 떨어뜨리는 등 문제를 야기 시킬 수 있음에도, 기존 모바일 애플리케이션 관련 연구들은 주로 사용성 중심의 만족을 다루었다. 따라서 본 연구에서는 이러한 의외성으로 인한 사용자 경험의 변화를 세렌디피티(뜻밖의 발견으로부터 유발되는 예상치 못한 즐거움) 개념을 이용하여 모바일 애플리케이션의 UX 분야에서 실험적으로 확인하고, 이로부터 유발되는 요인이 사용자 만족에 미치는 영향에 대해 관찰했다. 즉, 모바일 애플리케이션의 인터랙션을 통해 유발시킨 의외성과 동시에 게임 요소를 제공한 세렌디피티, 지각된 신규성과 지각된 사용 용이성, 지각된 유용성, 그리고 만족 등의 요인들 간 관계를 살펴봤다. 그 결과 세렌디피티가 지각된 신규성에 정(+)의, 사용 용이성에 부(-)의 영향을 미치고, 지각된 신규성과 지각된 사용 용이성이 지각된 유용성에 정(+)의 영향을 미치며, 세 가지 요인 모두 사용자 만족에 정(+)의 영향을 미치는 것이 관찰됐다.

미니멀리즘은 단순성, 명료성, 반복성, 배제성을 특징으로 장식을 배제한 절제의 미학을 의미하고, 스큐어모피즘은 복고와 기능, 그리고 감성을 특징으로 어떤 대상물을 이해하기 쉽도록 유사한 형태로 디자인한 미학적 관점을 의미한다. 모바일 플랫폼의 인터페이스는 이러한 두개의 미학적 특징을 바탕으로 개발되었는데, 본 연구에서는 이러한 미학적 특징을 갖는 대표 사례로써 애플의 모바일 운영체제인 iOS6과 iOS7을 대상으로 사용성 평가를 진행했다. 통해 이 용자는 어떻게 경험하는지를 평가한 결과, iOS6을 스큐어모피즘으로, iOS7을 미니멀리즘으로 인식하고 있다는 것을 알 수 있었다. 인터페이스 구성 요소를 변인으로 살펴보았을 때, 타이포그래피와 정체성 변인이 유의미한 차이가 있었고, 하위변인에서는 타이포그래피 변인에서는 심미성 변인만이 그리고 아이콘 디자인 변인에서는 이해가능성을 제 외한 정확성, 심미성 그리고 일관성에서 유의미한 차이를 보여주었다. iOS6는 정확성에서는 더 뛰어났지만, iOS7은 나머지 차원에서 더 우수한 것으로 평가되어 연구참여자들은 iOS7에 더 긍정적인 태도를 보이는 것으로 나타났다.

As a macroscopic research for the interaction of mobile game platform, I have analyzed the differentiation & characteristic of interaction for each platform. ‘Game & Watch’ was the first handheld game console released by Nintendo in 1980, the initial model was merely a combination of clock and game consoles to emphasize mobility. However, ‘Game&Watch:DonkeyKong’ which equipped with Yokoi Gunpei’s cross key provided an opportunity for the development of a full-fledged multi-screen gaming. ‘GameBoy’ was the beginning of a portable game machine in the modern sense. It has brought a lot of changes for the gameplay pattern using the contrast of color, smooth animation, as well as interchangeable cartridge system. Also, ‘NDS(Nintendo DS)’, which had several interaction system such as dual screen, voice input and touch input, had contributed to expanding the emergence of innovative game content and women game users. ‘PSP(Playstation Portable)’ by SONY in 2004 materialized 3D games using high performance and progressed to multimedia platform.

This paper presents a Cocos2d-x-based mobile game using a twisted GFSR-PRNG (Generalized Feedback Shift Register - Pseudo-Random Number Generator), known as the Mersenne Twister, with a super astronomical cycle of 219937 - 1, and good virtual randomness in up to 623 dimensions, to deal with random factors for use on Android. Especially, if there are several rand() function calls at the same time, when a user plays the game, the dots do not fit. The Cocos2d-x-based mobile game shows the Mersenne Twister MT19937 is suitable and much faster than rand(). In addition, anyone who has a smart phone can easily install the game and play it. In this game, the player controls his or her own aircraft to destroy the enemy while avoiding obstacles. One key point of this game is that various effects are assigned to each image frame. Moreover, this game is special because it allows the player to produce something called small boss mobs and large boss mobs, providing various types of attached projectiles, upgrading to 10 stages in total and enemies that appear accordingly, and giving items that burst out laughing during the game.

Today, mobile advertising is an important tool as interactive communication has a great potential to promote market sales. This study is to examine the effect of price perception on behavioral intention to use mobile phone-based promotions, and compare the differences in choice heuristics between levels of the intention to use mobile promotions. Multi-item scales for price perception, choice heuristics and mobile-based promotions were either developed in our qualitative study or adopted from existing scales in literatures (Lichtenstein, et al., 1993; Bettman & Park, 1980). Based on behavioral intention to use, mobile promotions were classified into three types, such as sales promotion, reward program and brand ads. All items were measured on a seven point rating scale (1=very unlikely, 7=very likely). A pilot study was conducted in which 97 female consumers who had ever redeemed mobile promotions for purchasing fashion products. Respondents were aged from 18 to 35 years (average age=23.6 years). Factor analysis revealed that price perception extracted three factors, such as price consciousness (items =4, Cronbach’s α=.90), coupon proneness (items =5, Cronbach’s α=.89), and sales proneness (items =4, Cronbach’s α=.89). Regression analysis was used to examine the effect of the price perceptional factors on use intentions for mobile promotions. For sales promotion, price consciousness (β=.27, p<.01) and coupon proneness had significant effects on intention to redeem for sales or coupon (F=13.59, p<.001, Adjusted R2=.29); price consciousness (β=.22, p<.05) and coupon proneness (β=.36, p<.01) significantly affected behavioral intention to participate in reward program (e.g., QR code events, point mileage, free gift, etc.) (F=10.34, p<.001, Adjusted R2=.23); and intention to use brand ads was significantly affected by sales proneness (β=.26, p<.05) and price consciousness (β=.24, p<.05; F=9.18, p<.001, Adjusted R2=.21). For purchasing in mobile context, consumer choice heuristic was consisted of five rules: compensatory, lexicographic, price-based conjunctive, affect-referral heuristic and sequent elimination in the mobile context. It is found that consumer choice rule was differed by intention to use mobile promotions. There was a significant difference in lexicographic (MLow=3.89, MHigh=4.63, t=-3.54, p<.01), price-based conjunctive (MLow=3.64, MHigh=4.13, t=-2.12, p<.05), and affect-referral heuristic (MLow=3.31, MHigh=4.02, t=-2.95, p<.01) between high and low levels of use intention for redemption for sales or coupon; for reward program, there was significant difference in price-based conjunctive (MLow=3.45, MHigh=4.27, t=-3.72, p<.001) or sequent elimination (MLow=4.39, MHigh=5.00, t=-2.13, p<.05) between the high and low levels of use intention. Also, there was a significant difference in price-based conjunctive rule between high and low levels of use intention for brand ads (MLow=3.49, MHigh=4.30, t=-3.76, p<.001). The findings extended a consumer choice model under mobile promotional stimuli and discussed a managerial implication to build effective promotional strategy in the context of mobile commerce..

The purpose of this study is to identify mobile commerce characteristics and their influence on consumer’s purchase intention in mobile fashion shopping mall. To figure out the path of influence, TAM (Technology Acceptance Model) was applied. This model explained attitudes and behaviors of users toward acceptance of innovation technology like information technology. Davis (1989) proposed perceived ease of use (PEOU) and perceived usefulness (PU) as belief variables affected attitudes of users and the attitudes in turn affected the intention of acceptance in acceptance of information technology. However it is necessary to incorporate additional constructs to the original model in the quest for increased predictive power to explain consumer’s purchase intention (PI) in mobile shopping mall. Clarke (2001) suggested constructs of mobile commerce characteristics as ubiquity, convenience, localization, personalization and so on differentiated from internet commerce. Therefore, ubiquity, personalization and enjoyment were included as external variables to explain mobile commerce characteristics besides PEOU and PU in this study. 436 adults in their twenties and thirties which were included in panels of specialized Internet research institutions nationwide were answered on questionnaires about mobile commerce characteristics, PEOU, PU, PI (Purchase Intention) and demographics. Structural equation model was made to examine the entire pattern of inter-correlations among the constructs and the hypothesis of each path was verified using AMOS 16.0 package. As a result, the fitness of the extended TAM to explain the influence of mobile commerce characteristics on consumer’s purchase intention in mobile fashion shopping mall was proven.

Recent university students are under a lot of stresses due to academic performance, employment, and anxiety about the future in the fierce competition. Mobile games can be used as a plan which can reduce the stresses of these students. However, if they play too long the games, it will cause another big problems. In this paper, we experimented to look for the best mobile game time to alleviate the stresses of university students as follows. First, we chose 16 people which have more stress load than the average student through stress tests by the basic diagnosis questionnaire. Second, we did total eight experiments on the stresses of the subjects in the study. That is, the experiment was carried out once before the test, 6 times for the mobile game (60 minutes), and once before the experiment. Third, we did T-test and multivariate analysis on the collecting data. As a result, it is proved that the mobile game for about 20 minutes could derive the effect on reducing stresses.
