Towing vessels have carried out the important role and service in the maritime industry construction, such as port and sea bridge construction, fairway dredging and sea reclamation etc. Furthermore, tugboat takes the largest portion in number of vessel at the domestic registry and barges as big as the general merchant vessel, which are getting specialized and larger, are in operation. In spite of the increase of marine accidents under this situation, there has been no proper measure for the safe navigation of tugboat in the aspect of a nation. This paper aims to propose the measure for the safe navigation of tugboat according to the frequent marine accident of tugboat with sea bridge. Therefore, we show an example of the sailing schedule and operation checklist based on the analysis of statistics and precedent of marine accident and the investigation of the actual operation state of tugboat in the aspect of a contract of carriage and a personnel setup, which should be checked by the operator of tugboat, to pass through sea bridge safely and propose the safe traffic supporting system based on electronic chart system to improve the safe navigation of tugboat.

The purpose of this article is to investigate the relation the animation to culture archetype, focusing on the case of the matter for animation content creation. Furthermore, in the paper, we also study about the animation industry development using various cultural archetypes such as the tale, myth, legend, folk tale, which are usable for animation content industry. For purposes of this study, we analyzed the aspects of power of folk tale and the essential vitality of folk tale in KBS Satellite Channel's and Michel Ocelot's $\grave{e}$re>. Above all, the origin of literature, folk tales are characterized by their uniqueness of each people as well as the global universality, being reproduced over and over again in oral literature. In the existent mode, folk tales have a firm structure because of storytelling, and have characteristics of performance and tradition on the basis of this structure. These characteristics can make emotional experience deepen and insure quality of narrative experience through direct communications. In this context, comparing folk tales of diverse forms of each nation and discovering the ethnicism and universality would not only be critical in the animation content development aspects, but provide precious data for effective animation marketing to apply One Source-Multi Use.

Purpose - As recently social contributions of firms are positioned as key strategic actions, it is demanding to review the effects of social contributions on overall corporate management. The research aims to effects of social contributions on social values and word of mouth in firm level and product level. Further roles of consumer identification with firm and product eco-friendliness are also analyzed. Research design, data, and methodology - The paper conducted a survey in which two scenarios are used for manipulating the degree of corporate social contributions. The survey sample consist of 165 undergraduate and graduate students in a university, located in Seoul. For analyzing data, analysis of variance is applied, in conjunction with analysis of moderating effects, through version 23 of SPSS statistical package. Results - In the firm level, social contributions by firms have a positive effect on social values of firms. Consumer identification showed a moderating role in the effect. Social value of the firm with passive social contribution perceived by respondents with a high degree of identification was higher than social value of the firm with active social contribution perceived by respondents with a low degree of identification. Corporate social value has positive effect on word-of-mouth of firms. In the product level, social contributions by firms has a positive effect on social values of product. Product eco-friendliness showed a moderating role in the effect. For eco-friendly product, social values are higher in the firm with active social contributions than in the firm with passive social contributions. However, for non eco-friendly product, the difference in social values between the two firms does not exist. Product social values has positive effect on intention for WOM of products. WOM of eco-friendly products with low social value showed no difference with WOM of non eco-friendly products with high social value. Conclusions - These results imply that firms should enhance consumer identification with firm in making social contributions for optimizing corporate social value and enhancing word-of-mouth(WOM). Managerial implications of the results suggest it would be more effective to improve social value of product by active social contributions for increasing word-of-mouth(WOM) of product.

This study is primarily aimed at conducting conceptual research that reinforces corporate social responsibility and gives direction to how local firms' CSRs should evolve in line with global CSR core values. To this end, a comprehensive approach was made to the Korean CSR system or standards in terms of research methods, and the direction of development was derived by comparing them with global standards. While the social responsibility activities of Korean companies are still focused on social contribution, CSR activities of global companies take social responsibility not only in various business areas but also in the circumstance surrounding companies, labor, environment and others. In particular, they are conducting stable CSR activities within the value chain of companies. Moreover, the CSR function is required in both the original and the primary sub-contractors and the secondary sub-contractors. This can confirm that the CSR activities of companies contribute to the development of society as they attract better working conditions and a better living environment based on the CSR. Therefore, the CSR direction presented by the study is meaningful and worthwhile in that it can contribute not only to Korean companies' global advancement but also to transform our society into a better society.

Software, once developed, has a long life and evolves through numerous additions and modifications because of the faults, the changes in user requirements, the changes in environments, and so forth. With the evolution of the software, assuring the quality of the software is getting more difficult because of numerous versions of the software. Meanwhile, regression testing has been used to support the software testing activities and assure acquiring appropriate quality through several versions of software. Regression testing, however, is too expensive because it requires lots of test cases executions and the number of test cases increases sharply as the software evolves. For this reason, several techniques are suggested to help conducting regression testing then test case prioritization technique is understood the most effective and efficient technique to support regression testing. In this paper, we propose an approach, Historical Value-Based Approach, which is based on the use of historical information to estimate the current cost and fault severity for cost-cognizant test case prioritization. As a result of the proposed approach, software testers who perform regression testing prioritize their test cases more effectively so that the test effectiveness of them can be improved in terms of APFDc.

This study examines subjects' eye movement pattern and surveys their attitudes to the exposed advertisements on the Facebook. Different from the F-shaped pattern of the typical Web pages, users' eye movements on the Facebook have shown a rough H-shape. Even though a large number of users have shown F-shaped pattern on the ordinary Web pages in order to skip the contents of a Web, subjects' eye-movement pattern on the Facebook has H -shaped pattern due to the unique User Interface (UI) of the Facebook. With the right side and vertical arrangement of ads on the Facebook, users skip the page with having a large H-shaped pattern. In addition, this study set four AOIs(Area of Interest) that are advertising sections comprised on the Facebook Web page and measured fixation length within the AOIs then surveyed subjects' attitudes about the exposed ads. Through the experiment and survey, this study offers the optimum advertising position that can attract Facebook users' attention. As the result of experiment and survey, the second ad has the subjects' highest attitude to advertising and fourth ad is the next effectiveness and first and third ad followed. This study highlights the key implications to provide better user experiences(UX) and marketing strategies to users who are the consumers of companies and organizations which have a plan to put their advertising on the Facebook.

In this paper we address the MBR-safe property of Piecewise Aggregation Approximation(PAA), and propose an of efficient subsequence matching method based on the MBR-safe PAA. A transformation is said to be MBR-safe if a low-dimensional MBR to which a high- dimensional MBR is transformed by the transformation contains every individual low-dimensional sequence to which a high-dimensional sequence is transformed. Using an MBR-safe transformation we can reduce the number of lower-dimensional transformations required in similar sequence matching, since it transforms a high-dimensional MBR itself to a low-dimensional MBR directly. Furthermore, PAA is known as an excellent lower-dimensional transformation single its computation is very simple, and its performance is superior to other transformations. Thus, to integrate these advantages of PAA and MBR-safeness, we first formally confirm the MBR-safe property of PAA, and then improve subsequence matching performance using the MBR-safe PAA. Contributions of the paper can be summarized as follows. First, we propose a PAA-based MBR-safe transformation, called mbrPAA, and formally prove the MBR-safeness of mbrPAA. Second, we propose an mbrPAA-based subsequence matching method, and formally prove its correctness of the proposed method. Third, we present the notion of entry reuse property, and by using the property, we propose an efficient method of constructing high-dimensional MBRs in subsequence matching. Fourth, we show the superiority of mbrPAA through extensive experiments. Experimental results show that, compared with the previous approach, our mbrPAA is 24.2 times faster in the low-dimensional MBR construction and improves subsequence matching performance by up to 65.9%.
