With the increased economic profit in China, people tend to give more attention to the nurturing of children. The change in the food markets directly connected to the infants' health seem to have brought various consumption patterns different than before. Based on the actual condition survey operated by this research, the expansion in the scale of consumption and preference to the imported food for infants appeared in the Chinese food markets for infants. The rapidly increased amount of the online purchases of the food for Chinese infants was checked through the condition survey. Based on the analysis results, with the purpose of increasing the purchase opportunities of the Korean food for infants to the Chinese consumers, it should not only perform the promotion activities such as the promotion for the product's superiority and various promotional event, but also establish the pricing strategy for each entry step to the Chinese market. Because the purchase experience of the Korean food for infant plays the important role for the additional payments decision, it is estimated that there is a need to expand the opportunities for the Chinese consumers to approach the Korean food for infants both directly and indirectly.

An unconstrained three-dimensional cutting problem describes the process of finding the cutting pattern that yields the maximum total profit-sum for the small parallelepipeds pieces cut from a large parallelepiped box and there is no limit to the number of pieces to be cut. The problem is a classic NP-hard. The bottom-up approach, which generates all of the feasible cutting patterns by combining two other cutting patterns, can be applied to the three-dimensional problem. We introduce a build and new branching strategies for the unconstrained three-dimensional cutting problem. The strategies are all generalized from the branching strategies proposed by G et at. to solve unconstrained two-dimensional cutting problems.

Purpose: This study aimed to explore the discourses and the patterns of problem solving behaviors among the nurse managers. The focus of the study was the difficult situations in caring with patients and their families. Methods: Field study was performed at a for-profit hospital from March, 2004 to March, 2007. The participants of the study were 5 head nurses and 2 nurses in charge. The data were collected with iterative interviews and participant-observations. For the analysis of the data, taxonomy and critical discourse analyzing were applied. Results: The nurse mangers who showed wholistic patterns of behavior took the role of a broker among the client system, professional nursing system, medical system, and other allied health system. The nurse managers whose approach was profession-centered took the role of protector of nursing system. The nurse manager who practiced nurse-oriented pattern of behavior tried not to have harm against other members of health system. The experiences of nurse managers were effected from the discourses of patriarchal and market mechanism. Conclusion: The situation that provoke conflict between clients and nurses become more common with the changes to the health care system and to society. Nurse managers take the role of these conflict problems. The successful solving of conflict in a nursing care setting promotes the quality of care and satisfaction of clients. Programs for enhancing nurse's problem solving competency should anchored be in their practices.

Citing literature is a very important activity for scholars in writing articles. Many publishers and libraries build citation databases and provide citation reports on scholarly journals. Cited-by linking is a service representing what an article cites and how many times it cites a specific article within a journal database. Recently, information services based on DOIs (Digital Object Identifiers) have been increasing in number. CrossRef, a non-profit organization for the DOI registration agency, maintains the DOI system and provides the cited-by linking service. Recently, the number of Korean journals adopting DOI is also rapidly increasing. The Korea Institute of Science and Technology Information (KISTI) supports Korean learned societies in DOI related activities in collaboration with CrossRef. This study analyzes cited patterns of Korean DOI journal articles using CrossRef's cited-by linking data and a Korean journal citation database. This analysis has been performed in terms of publication country and the language of journals citing Korean journal articles. The results show that DOI, SCI(E) (Science Citation Index (Expanded)), and English journals are more likely to be cited internationally.

The purpose of this study were to analyze the consumption patterns of animal foods during the sixteenth century through Shamirok. There were eleven animal foods : beef, pork, chicken, pheasant, deer, roe, lamb, bear, fox, sparrow, and horse. The most frequently consumed were in the order of pheasant, doe, and chicken. There were 44 fish consumed, including flatfish, hairtail, mackerel, flounder, kumlin fish, bass, null fish, codfish, and red snapper, as well as four mollusks and six shellfish. Eggs and fish egg were also consumed. These foods were cooked as Tang(湯), Gui(灸), Po(脯), Hoe(膾), and Sookyook(熟肉), or processed after being dried or salted. The animal foods were mostly consumed as Po and Tang in daily eating and for formal dishes. Fish were mostly consumed as Jockgal or Shikhae. The foods were primarily acquired by donation from local officials or relatives ; secondly by independent poultry farming, fishing, or hunting, along with the production of grain and thirdly through barter with rice and textiles. Food were sometimes traded for profit, but such acts of trading while living ; as wartime refugees was a meager means for living.

In this paper I examined trades of general bank In KTB212 Futures for patterns which are best described by the behavioral finance literature. I reported the statistics for traders of profit or loss traders, number of traders, total trader gross trading income, revenue per contract. Thess results are acquired from the revenue scale and the trade contract scale. When traders are ranked on the basis of performance, successful winning traders are short positions in the KTB212. This result appears more faithful to large scale traders. The evidence suggests that large traders are able to act on the information flow. The measure of success is as total income, and the relationship between position holding and success is clear.

This paper presents a decision making model for the cruise ship management. A network based optimization model has been developed for a single cruise ship operation. It gives optimal itinerary patterns over the planning period for the cruise ship managers wanting to maximize profit from the cruise ship operation. A network solution method to find the optimal solution is also developed. This network model can be equivalently transformed into a linear programming model, which makes the implementation of the model quite practical however complicated the given set of possible itineraries may be. The ship scheduling network developed in this study can also be used as a general framework to describe all possible cruise ship itineraries the cruise ship manager can figure out.

In the recent Internet environment, there are different competition patterns among competitors as it was before. As we see real world example such as Covisint in automobile industry and Exostar in aerospace industry, collaboration among competitors now takes place and industry-wide B2B marketplaces come into existence. Hence, we suggest the extended system dynamics simulation model based on Kim(2002)’s collaboration profit models in order to explain competitors’ collaboration in the e-business environment. After all, we investigate the necessity of collaboration between competitors, and show the presence of the optimal investment decision making to collaborate. We also show that the effect of collaboration is changed as varying the industry characteristics such as standardization and volatility.

The increasing late-payment rate of credit card customers caused by a recent economic downturn are incurring not only reduced profit of department stores but also significant loss. Under this pressure, the objective of credit forecasting is extended from presumption of good or bad customers to contribution to revenue growth. As a method of managing defaults of department store credit card, this study classifies credit delinquents into some clusters, analyzes repaying patterns of customers in each cluster, and develops credit forecasting system to manage delinquents of department store credit card using data of Korean D department store's delinquents. The model presented by this study uses Kohonen network, a kind of artificial neural network of data mining techniques to cluster credit delinquents into groups. Logistic regression model is also used to predict repayment rate of customers of each cluster per period. The accuracy of presented system for the whole clusters is 92.3%.

When the high voltage is applied on insulation materials that have voids and impurities inner one, then probability of electrical tree inception is increased at defects. Electrical tree gives a profit to degradation analysis, because it is possible to observe by eyes and provides electrical degradation step. And electrical tree is divided to three types in usual - tree type, bush type and chestnut type tree. But these three types are divided not by method of quantitative analysis but visual and experiential analysis. In this paper, three types of electrical tree were calculated by quantitative analysis using fractal mathematics and classified to fractal dimensions (FD). FD of tree types are 1.1$\sim$1.4, bush types are 1.4$\sim$1.6 and chestnut type trees have above 1.6 FD.
