This study was conducted to assess factors associated with the degree of performance of qualify improvement(QI) activities. A mailed questionnaire survey was conducted between September 15 and October 30, 2000, with the staffs being charge of QI at each of the hospitals with 400 beds or greater. Of the 108 hospitals eligible for inclusion in our study, 79 participated, yielding a response rate of 73.1%. After excluding 12 hospitals that did not perform any QI activities, 117 responses from 67 hospitals were used for the analysis. Using the Malcolm Baldrige National Quality Award Criteria(MBNQAC), perceived performance of QI was measured in terms of the improvement of the quality of clinical practice, clinical supporting department, administrative procedure of receiving care, customer satisfaction, efficiency and standardization of work process. Factors evaluated for the association were the extent of QI implementation, compliance to 5 QI principles, participation of hospital CEOs, budget allocation, history of QI, and bed size. Path analysis was performed to assess the relationship between QI performance and these factors. Major findings of this study are as follows. Hospitals showing higher degree of QI implementation (path coefficient=0.5967, p<0.001)) and better compliance with the basic principes of QI(0.5736, p<0.05) tended to achieve better performance. Path analysis results showed that interest and participation of hospital CEOs(0.1954, p<0.05) and compliance with the basic principes of QI(0.4028, p<0.0001) indirectly affected the outcomes of QI by influencing the intermediate variable of the level of QI implementation. This study results suggest that having employees have a good orientation of the basic concept and principes of QI through relevant training be the most important requirement to achieve better outcomes from QI activities. In addition, to educate leaders of hospitals the need of active implementation of QI is important to encourage their participation and draw strong support for QI programs.

In the midst of worldwide response to climate change, the advanced ports including LA/LB(Los Angeles/Long Beach) has started to reduce carbon emission from port area which has not been targets of interests in the worldwide cooperation. Recently, the Port of Busan has started to reduce carbon emission from the port area under the Green Port Strategy in Korea. However, the low-carbon port management increases the cost of port management and negatively impacts the port competitiveness in the short term. Therefore, the Busan Port Authority is carrying out the low-carbon projects directly and has not transfer the cost to the port users, such as shipowers, cargo owners and terminal operators. However, the Port Authority of LA/LB has transferred the cost at low-carbon port management to customers of port. In this study, comparative analysis on cost of low-carbon port management at Busan and LA/LB is carried out for sustainable port management.

Recently, global warming, energy shortage, and environmental disruption have been serious problems in every nation. It became more and more important to reduce the emission of CO2 and to use of energy efficiently. Smart grid was also introduced using the rapidly developing information technology. It deployed the mutual communication concept between customers and the suppliers in the electricity supply. There were increasing demands to adopt the smart meter and to present incentive for efficient energy usage in many developed countries. The objective of this research was to develop the optimal real time pricing model which maximized the profit of the power retailer and reduced the usage of energy. The simulation study was given to show the usefulness of the model. Simulation considered the customer demand response rate and price elasticity rate. The price elasticity rate was compared in the condition of fixed value according to time and variable value according to the customers. The optimal price model could maximize the profit of the power retailer and reduce the energy usage of the consumers.

The current challenge with which most shipyards are forced is to reduce the design time and the time-to-delivery because of explosive order of shipbuilding. Collaborative design and product data management have become important to reduce the lead time. Furthermore, enterprise information technologies such as ERP (Enterprise Resource Planning), SCM (Supply Chain management), and APS (Advanced Planning System) requires the collaborative environment. Also, manufacturing environment has been considered as a topic of strategic interest to get shorter product lifecycles in shipyards. Most shipyards have chosen an environment of ETO (Engineering To Order) strategy which designs and produces new products in response to various requirements of customer, rules and regulations. In the ATO (Assemble 10 Order) environment, most component parts have been designed to be procured or produced on the order requirement. The basic distinction between the ETO and ATO is the timing of the design. Thus in the ATO environment, it is more flexible in reducing the lead time to meet the specified requirements of customers. However, the ETO strategy requires new ship design process and ship product structures that are linked with the implementation of PLM. And, the function and architecture of current PLM solution has been designed based upon ATO environment properly. This paper presents the PLM architecture which effectively reflects the characteristics of shipbuilding. 4-layer architecture model is suggested to implement the PLM system. Also, implemented functions of ship PLM is explained in order to make a practical guidance for ship PLM implementation.

The proportion of software in the automotive industry is steadily increasing due to the rapid technological development of automobile E/E parts. Because the automotive E/E technology is now on the basis of intelligent automobile and advanced safety automobile technology. The purpose of this study is to investigate the effect of organizational capability (organizational resource capability and management capability), process capability (process capability, customer Requirement management capability), performance dimension (motivation, participation level). In this study, we conducted questionnaires and statistical analysis on engineers (members of the Korea Advanced Automotive Technology Association) who perform research and development activities in the R&D organization of the automotive E/E part in South Korea. ANOVA is applied for the verification of the difference in performance measured by organizational capability, process maturity, and motivation participation level according to company characteristics (level of processing : supply chain configuration, annual sales, total SW development ratio). According to the results of this study, in order to improve the performance of ASPICE or ISO 26262-related consulting project, a different consulting approach strategy considering the characteristics of organization and personnel is needed. In summary, the analysis results for the three main treatment levels are as follows. The difference in organizational capacity, process capability and performance was found to be statistically significant according to supply chain configuration and annual sales, but it was found that the difference of response according to the proportion of total SW was not significant.

This study is to respond to the urgent demands of both society and times on public schools in regards to training an educated person who can cope with the financial environment of this diversified modern society. Therefore, this study will explain the concept of Financial Consumer Education and its trends of several other countries. By focusing on the current state of Korean Financial Consumer Education, it will call attention to the needs of introducing Financial Consumer Education to the school curriculum in order to educate students about finance systematically. To support our viewpoint, this paper analyzed and organized the materials concerning Financial Consumer Education in two curricula (2007 and 2011 Revised National Curriculum), and in a Practical Arts (Technology Home Economics) textbook of the 2007 revised version. Hence, the purpose of this study is to explore the desired direction and revitalization of Financial Consumer Education by analyzing the existing curricula. Even though the content of finance education begun from one of the subcategories of consumer education called 'Financial Management,'the number of research about financial education through public education has been increased in response to the social and academic consensus. Therefore, we suggest the re-conceptualization of consumer education for financial education is necessary. Therefore, this paper suggests that Financial Consumer education in a Practical Arts (Technology Home Economics) should not be regarded as only one of the components of Consumer Education. Instead, by raising it to the status of Financial Customer Education, it is required to teach the learners to improve their personal financial management skill as well as to help them achieve financial knowledge, skill, and attitude as financial consumer.

The electronic stores have realized that they need to understand their customers and to quickly response their wants and needs. To be successful in increasingly competitive Internet marketplace, recommender systems are adapting data mining techniques. One of most successful recommender technologies is collaborative filtering (CF) algorithm which recommends products to a target customer based on the information of other customers and employ statistical techniques to find a set of customers known as neighbors. However, the application of the systems, however, is not very suitable for seasonal products which are sensitive to time or season such as refrigerator or seasonal clothes. In this paper, we propose a new adjusted item-based recommendation generation algorithms called the exponentially weighted collaborative filtering recommendation (EWCFR) one that computes item-item similarities regarding seasonal products. Finally, we suggest the recommendation system with relatively high quality computing time on main memory database (MMDB) in XML since the collaborative filtering systems are needed that can quickly produce high quality recommendations with very large-scale problems.

Contract Managed foodservice has been expanded rapidly in university foodservice operations. The purposes of this study were to examine customers and administrators' preference concerning operation format, the decision making components for operation format, and administrators' attitudes concerning contract managed and self-operated foodservice. Two types of questionnaires were developed and implemented. Customer and administrator's questionnaires were distributed to 900 university students and 27 administrators respectively, and 831 customers and 24 administrators were responded with a response rate of 92.3% and 88.8% respectively. Statistical data analysis was completed using the SPSS programs for descriptive analysis, $x^2$-test, ANOVA, and T-test. The results of this study can be summarized as follows 1. In deciding foodservice operation format, the components customers considered were the ability to provide variety of meal items, aesthetic and safe food(62.6%), the ability to provide a food with competetive low price(22.1%), and the ability to provide adequate service and nutrition information. On the contrary, the components administrators considered were the ability to provide variety of meal items, aesthetic and safe food(66.7%), the ability to relieve administrators of managerial burden of the foodservice operation(12.5%), and the ability to invest facility(8.3%). 2. The average score of attitude on contracted and self-operated management activities were 3.41, 3.10 respectively. University administrators evaluated that contractors performed financial management activities more effectively. 3. University administrators with contracted or self-operated foodservice favored their own current operation format.
