  • Generally, after stern tube bearing shows a significant increase in local load due to propeller load, which increases the potential adverse effects of bearing failure. To prevent this, research on regarding shaft alignment has been carried out with a focus on reducing the relative slope between the shaft and support bearing(s) under quasi-static conditions. However, for a more detailed evaluation of a shafting system, it is necessary to consider dynamic conditions. In this context, the results revealed that eccentric propeller force under transient conditions such as a rapid rudder turn at NCR, lead to fluid-induced instability and imbalanced vibration in the stern tube. In addition, compared with NCR condition, it has been confirmed that eccentric propeller forces given a rapid rudder starboard turn can lift a shaft from the stern tube bearing in the stern tube, contributes to load relief for the stern tube bearing.

  • Although music is one of the most important attributes of broadcasting communications, few studies have examined the relationship between background music and the behavior of audiences, particularly in the context of TV home shopping programs, where purchase decisions are made while watching the show. The objective of this study is to examine whether certain characteristics of music in broadcasting communications can affect the audiences' purchase intentions or behaviors. Unlike previous studies on this issue, this study considers the impulse-inducing capability (IIC) of music as an important variable affecting consumers' purchase intension. A 2×3 (high/low involvement and high/low/no IIC music) between subjects design was used for the experiments in the study. The TV home shopping programs in the high or low involvement condition were identical except for the type of background music: high IIC music, low IIC music, and no music. A total of 188 undergraduate students at a college in Seoul, South Korea participated in the study. Their ages range from 20 to 25 (median age = 22), and nearly 60% were male. Our analysis showed that in the low involvement condition, high IIC music was more likely to have a positive effect on purchase intentions than low IIC (common) music or no music did. Meanwhile, there was not any significant relationship between music and purchase intentions in the high involvement condition. Given that previous studies have provided no clear evidence of the effects of music on consumers' purchase intentions or behaviors, this study makes an important contribution to the literature in this field. The result of this study provides implications to the practitioners in the market, too. Marketers need to reevaluate the value of music used in broadcasting communications and pay more attention to find the right music for their campaigns. Limitations of this study as well as directions for future studies are also discussed.

  • Objective: The aim of this study is to offer a holism based Service Experience Analysis System(HSEAS) for service design. Background: Customer experience has been focused in a lot of service area. But it is difficult to understand the customer's needs and their experiences because it's so complex and uncertain. Thus it needs holistic approach that means it's difficult to explain general character merely through the understanding of small parts that composes an object and it must be analyzed within the overall context. Method: Accordingly, the thesis paper proposes the Service Experience Analysis System that satisfies the four following needs. (1) Need of solid Experience Framework in which the special quality of the service experience is considered, (2) need of support for the semantic cohesion between different kinds of data, (3) need of support for the management and search of vast data, and (4) need of building the knowledge base system for collaborative research. Results: HSEAS combines the short information in the customers' words and behaviors or situations and circumstances and provides a place of analysis where the context of the general experience can be read and allows concrete understanding of the actual state and factor of the problem as a Combined Data Analysis Tool. Conclusion: HSEAS becomes the center of information management, analysis and connection and it provides a free collaboration place where physical condition has no relations to as a knowledge base system based on network. Application: It is expected that length and width will be added to the analysis and assistance for effectively accumulating information will be provided in the area of diverse service.

  • Startup has lot of limitation such as time and budget shortage, and few human resources, and may be under the very stressful condition. Naturally in these context, there is always conflict among the startup team members, but the impact of conflict on teamwork or team performance has not been empirically tested. This study examines the relationship among the conflict, teamwork and team performance in startup context. Different two types of conflict and four factors of teamwork for team performance are identified from a literature review and tested; task conflict and relationship conflict as antecedents, teamwork was composed of communication, collaboration, coordination and cohesion, leading to team performance. 142 data points were collected from startup representatives to test these hypotheses. PLS data analysis indicated that the task conflict positively effects on all teamwork factors, but relationship conflict has statistically significant effect on only two teamwork factors, collaboration and coordination in negative relationship. Teamwork factors effects on team performance except communication. Based on the results, we proposed practically several team management skills for startup managers, leaders and even members, and explained theoretical contributions.

  • Amidst a competitive environment, success and innovation of a company hinge on establishment of competitive strategies through CEO's capabilities for discovering new businesses. In other words, several alternatives that are being considered as new businesses and the ensuing selection that a top management makes lead to a company's success and innovation. Examples of this are numerous among global corporations as well as Korean small and medium-sized enterprises (SMEs). This research has analyzed the role of a CEO to be a condition for success in the growth and innovation of a company. Starting from the topic of entrepreneurship, the research on the role of a CEO has been actively conducted in context with the latest innovations. A prime example involves research related to the innovativeness of a CEO. In this regard, this research was an empirical analysis on the impact that a CEO's ability to discover new business opportunities and competitive strategies has on the performance of a firm. This analysis was conducted based on nationwide data of 286 large conglomerates and smaller-sized companies alike. Based on the analysis, "experimenting" and "association", among abilities of discovery, have been found to strengthen competitive strategies. Also in the context of abilities needed for discovery, differentiation strategy has a greater effect on a firm's performance than the cost leadership strategy. Furthermore, the mediating effect of competitive strategies was prominently displayed in experimenting and corporate performance.

  • The aim of this study is to provide practical guide for exterior design in apartment and to propose a device to improve the quality of residential environment by the color planning. Color is a language of context and used as a visual aid to recognize the objects and spaces in the world around us. In this sense, each color perception is unique to its own setting and not subject to any universal rules of thumbs, Therefore, when designing with color, each setting will demand its own specific set of rules. A balanced color scheme has to make the environment more pleasant for people to live in . Fro the exterior in housing the use of color has to be considered not just in its wider context of the architecture or surrounding but as an element of the life of the inhabitant. So it is considered on the type of people who will live in and visual condition of site. In this study , the objective model of systematic design process for environmental color planning is proposed on the basis of theroetical background and references investigated, By the existing thesis, resident's preference of the exterior color and foumular of composition in apartment was invastigated . In general theories, based on the theory Birren's color harmony for color coordination an design principles, a device of exterior color design in apartment was suggested by the course of reasonable design process. Color in environment plays many different roles. It integrates the architecture with the site. If color is use well, it can soften architecture that is too harsh, it can give a sense of identity to different part of site and improve a city's image. The environmental color is effective media to enhance the aesthetic value of architecture and environment.

  • This landscape design proposal was presented for a competition for mixed-use development project by project financing in Asan Baebang which was held by the Korea National Housing Corporation in July of 2005. The site is a center of Asan Baebang New Town Development District and has a commercial area of $57,929m^{2}$. Design guidelines and judging criteria of this competition were to build a symbolic center and cultural core for district, to elevate positive image and identity of Asan New Town by attractive place making, to link with separated block in the site and regional context, and to make environmentally sustainable design by creating an attractive waterfront of Jang Jae stream passing through the site. This is the most important condition for the design. Therefore, the authors developed design concept and strategy within the guidelines and this conditions. The schema of the design was introduced by the water in the site. To evolve design concept, we reinterpreted water and context in the site combining with landscape design strategy. So the proposal set the main design concept as 'all that is solid melt into water' as if Marshall Berman said. By doing that, design concept of the proposal evolved as follows: 'extension' of water and greer, 'a joint' of space,'newness' of experience, 'breath' of consensus with each other. The spatial concept of this project was developed by expressing five theme spaces; eco zone, entertainment zone, art zone, culture zone, leisure zone. These theme spaces were consecutively placed along the pedestrian path and to consists of vertical layer in each level and diverse design technique and spatial effects are used.

  • In sensor medium access control (SMAC) protocol, sensor nodes can only access the channel in the scheduling and listening period. However, this fixed working method may generate data latency and high conflict. To solve those problems, scheduling duty in the original SMAC protocol is divided into multiple small scheduling duties (micro duty MD). By applying different micro-dispersed contention channel, sensor nodes can reduce the collision probability of the data and thereby save energy. Based on the given micro-duty, this paper presents an adaptive duty cycle (DC) and back-off algorithm, aiming at detecting the fixed duty cycle in SMAC protocol. According to the given buffer queue length, sensor nodes dynamically change the duty cycle. In the context of low duty cycle and low flow, fair binary exponential back-off (F-BEB) algorithm is applied to reduce data latency. In the context of high duty cycle and high flow, capture avoidance binary exponential back-off (CA-BEB) algorithm is used to further reduce the conflict probability for saving energy consumption. Based on the above two contexts, we propose an improved SMAC protocol, micro duty adaptive SMAC protocol (MDA-SMAC). Comparing the performance between MDA-SMAC protocol and SMAC protocol on the NS-2 simulation platform, the results show that, MDA-SMAC protocol performs better in terms of energy consumption, latency and effective throughput than SMAC protocol, especially in the condition of more crowded network traffic and more sensor nodes.

  • Considerable research in dieting has examined the goal priming effect that promotes successful dieting. However, priming literature found that the process of which priming is led to behaviors involves not only the priming construct itself but the momentary self-concept activated by the priming. Based on this notion, studies examined whether the active self-concept as an "unsuccessful dieter" or "successful dieter" determines the priming-to-behavior effect in dieting. Study 1 used contexts of the prime as manipulation for participants' active-self following the prime and measured their chronic self-concept in dieting (rated on the Perceived Self-Regulation Success [PSRS] in dieting scale) as a moderator. The result supported the active-self account for the effect of the dieting prime. The interaction of the PSRS scores and the priming contexts was found in the dieting behavior of participants. Participants whose chronic self-concept in dieting is unsuccessful (the low PSRS) showed the goal-congruent priming effect only in the condition where the priming context reminded them of their self-concept in favor of dieting success. In the context where their dieting failure in the past became salient, however, the participants with the low PSRS were more likely to succumb to tempting food. In contrast, eating behaviors of the high PSRS participants were independent of the contexts. Study 2 tested a possible mechanism from the active-self to the behaviors. It is concluded that the active-self operates in the priming process by influencing anticipatory thoughts rather than automatic responses toward foods. The implications for understanding repeated dieting failures and designing practical interventions to help dieters are discussed.
