The purpose of this study was to investigate the shopping condition of Dongdaemoon Shoppingmall. A depth interview was administered to eight consumers aged 10s through 30s who had shopping experiences at Dongdaemoon Shoppingmall. The contents of interview were about the reasons of preference for Dongdaemoon Shoppingmall, the merchandise categories purchased, assortment, price, shopping environment, and service offered by Dongdaemoon Shoppingmall. The results of this study were as follows: The reasons of consumers' Dongdaemoon Shoppingmall preference were reasonable price, variety of merchandise assortment, easy catch of fashion trend, entertainment place, and opening hour at nighttime. The mainly purchased items were casual and fashionable clothes. Children's wear was mainly bought item by housewives too. The unique design, similar merchandises sold at department stores and new style in early adoption of fashion cycle were perceived as positive aspects, but copied merchandises and large quantity of same merchandise as negative aspects. The fixed price system was not trusted by consumers. Consumers' complaints about shopping condition were crowded pathways and shopping booths, the lacks of facilities such as fitting room, toilet, lounge area, sales persons' service, and difficulty of using credit cards. From these results, some implications for marketing strategies and practices might be suggested. In order to improve the design variety of merchandises, marketers and apparel manufacturers should make efforts by managing merchandise planning, production, selling, and promotion cooperatively. Fixed price system, acceptance of credit cards, and merchandise return/exchange service should be improved. The training the salespersons was the most important and basic step and easy way to get to successful business.

The recent Korean mathematics curriculum stresses to teach mathematics focusing on mathematical process composed of problem solving, reasoning and communication. To be successful in applying the rationale of the process-focused mathematics education, the assessment practice in classrooms should be also centered on mathematical process. In this study we conducted a large-scale survey on teachers' perspectives about the process-focused mathematics assessment. First, we surveyed teachers' opinion on current assessment practices in school mathematics related to regular school exams and performance assessments. Second, we investigated teachers' perception on mathematical process components such as problem solving, reasoning, and communication regarding how they should be assessed. Finally, we examined the difference of teachers' opinion according to their teaching experience, city size, and the type of school. Based on the results, we discussed implications for mathematics assessment and process-focused mathematical assessment.

The Internet telephony service is one of the commercially successful Internet application services. VoIP technology makes the service come true. VoIP deploys H.323 or SIP as the standard protocol for the distributed multimedia services over the Internet in which QoS is not guaranteed. VoIP carries the packetized voice over the RTP/UDP/IP protocol stack. The data transmission trouble is caused by UDP when the service is provided in private networks and some ISP-provided Internet access networks in the private address space. The Internet telephony users in such networks cannot listen the voices of the other parties in the public Internet or PSTN. Making the problem more difficult, the Internet telephony service considered in this paper gets the incoming voice packets of every session through only one UDP port number. In this paper, three schemes including the terminal proxy, the gateway proxy, and the protocol translation are suggested to solve the problems. The design and implementation of the NAT proxy server based on gateway proxy scheme are described in detail.

Recently, various methods derived from the experiences and the practices to manage knowledge have been proposed. However, the effects of the most of those methods have not been demonstrated quantitatively, but only the successful cases reported. In this paper, a method for knowledge transfer in a group is proposed to evaluate the effect of knowledge management and to express a shape that knowledge is transferred in the group by the multi-agent simulation. Simulation results show that the performance of the entire group is improved by introducing a knowledge database and a knowledge manager. In addition, the experience knowledge of the entire group is shown to be lost by reviewing results of the social issues by the proposed method. As a countermeasure for that, it was confirmed that the introduction of the knowledge database and the knowledge manager is more effective than those of an extension of the retirement age and of an increase of the intermediate recruitment.

Both undergraduate and graduate programs in health services management(HSM) are recently established in colleges and universities in Korea, and the programs train their students for diverse sectors within the field of healthcare management, including hospitals, nursing facilities, consulting firms, health industries such as pharmaceutical, insurance companies, etc. This study investigates many of the managerial roles expected to graduates from academic curricula in HSM, and required competencies to be successful in their positions. The information of roles and competencies for HSM graduates were collected, and their importances were evaluated by healthcare management experts through a Delphi method. As the result, 11 items for present roles and 13 items for future roles were derived, and 15 and 16 items were derived for present and future competencies respectively. Utilizing the classification of work roles by Timmreck and that of managerial competencies by Robbins, the importance of roles and competencies of healthcare managers was analyzed and interpreted. The major domains of roles at present turned out to be 'organizer', 'planner', 'problem solver', and 'coordinator' in order according to importance. On the other hand, as graduates develop their careers, the domains of future roles would be changed to 'director' and 'planner'. For competencies, the most important domain at present was 'technical skill', but the future important domain was 'interpersonal and emotional intelligence'. The result of this study can be seen as an initial step toward improving the academic curricula of HSM in college and universities and promoting collaborative efforts between academic programs and on-site practices in healthcare industries.

Background: To elucidate the relationship between safety culture maturity and safety performance of a particular company. Methods: To identify the factors that contribute to a safety culture, a survey questionnaire was created based mainly on the studies of $Fern{\acute{a}}ndez-Mu{\tilde{n}}iz$ et al. The survey was randomly distributed to 1000 employees of two oil companies and realized a rate of valid answer of 51%. Minitab 16 software was used and diverse tests, including the descriptive statistical analysis, factor analysis, reliability analysis, mean analysis, and correlation, were used for the analysis of data. Ten factors were extracted using the analysis of factor to represent safety culture and safety performance. Results: The results of this study showed that the managers' commitment, training, incentives, communication, and employee involvement are the priority domains on which it is necessary to stress the effort of improvement, where they had all the descriptive average values lower than 3.0 at the level of Company B. Furthermore, the results also showed that the safety culture influences the safety performance of the company. Therefore, Company A with a good safety culture (the descriptive average values more than 4.0), is more successful than Company B in terms of accident rates. Conclusion: The comparison between the two petrochemical plants of the group Sonatrach confirms these results in which Company A, the managers of which are English and Norwegian, distinguishes itself by the maturity of their safety culture has significantly higher evaluations than the company B, who is constituted of Algerian staff, in terms of safety management practices and safety performance.

This study aims to establish a strategic NSDI (National Spatial Data Infrastructure) model for developing countries based on good practices in the Republic of Korea. The Republic of Korea is a unique country in the world, which has become a developed country from a recipient of international aid since the Korean War in 1950. The rapid economic growth can be mostly attributed to the IT technologies and the Republic of Korea's NSDI efforts as a good practice could provide useful lessons for developing countries. This study consists of theoretical reviews, interviews of Korean NSDI experts, analysis for lessons learned, a summary of the lessons in terms of Six NSDI components and finally a strategic NSDI model for developing countries. The NSDI model is structured by (1) implementation strategies suggested for geospatial data, capacity building, geospatial platform, and cost-effective management with partnership, (2) a roadmap of important NSDI tasks and activities, and finally, (3) a harmonized approach for successful NSDI implementation.

This qualitative research investigated how to improve preservice and in-service teacher education programs through in-depth interviews with 10 exemplary science teachers. Data from interviews were used to analyze how the teachers perceived current situations of teacher education and what they suggested as an improvement plan. In terms of preservice teacher education, exemplary teachers argued that teacher education programs should (1) ensure the teacher education program's identity and goals, (2) provide preservice teachers with practical knowledge by translating theory into practice, and (3) secure faculty members who majored in science education. In light of in-service education, the teachers contended that (1) teachers should acknowledge the continuing processes of their own professional development, (2) the content and method of in-service training should incorporate teachers' practical needs in the classroom, and (3) the teaching community should implement a clinical supervision to improve their classroom practices. The central role of teacher (re)education in a successful classroom reform is also discussed.

Ever increasing fuel prices, almost doubled in the last three years, and global pressure to reduce their environmental impact have been enforcing commercial vessel operators and designers to re-assess current vessel designs with emphasis on their propulsion systems and operational practices. In this paper the "Inclined Keel Hull (IKH)" concept, which facilitates to use larger propeller diameter in combination with lower shaft speed rates and hence better transport efficiency, is explored for a modern 3600 TEU container vessel with the aim of fitting an 13 % larger diameter propeller (and hence resulting 20% lower rpm) to gain further power saving over the similar size basis container ship with conventional "level keel" configuration. It appears that successful application of the "inclined keel Hull" concept is a fine balance amongst the maximum gain in propulsive efficiency, minimum increase in hull resistance and satisfaction of other naval architectural and operational requirements. In order to make the concept economically more viable, this paper concentrates on the fore body design with the possible combination of increase of volume in its fore body to recover the expected volume loss in the aft body due to the space for larger propeller and its low wave-making resistance to minimize the efficiency loss using a well-established optimization software.
