There has been a gradually increasing focus on adopting mathematical modeling techniques into school curricula and classrooms as a method to promote students' mathematical problem solving abilities. However, this approach is not commonly realized in today's classrooms due to the difficulty in developing appropriate mathematical modeling problems. This research focuses on developing reformulation strategies for those problems with regard to mathematical modeling. As the result of analyzing existing textbooks across three grade levels, the majority of problems related to the real-world focused on the Operating and Interpreting stage of the mathematical modeling process, while no real-world problem dealt with the Identifying variables stage. These results imply that the textbook problems cannot provide students with any chance to decide which variables are relevant and most important to know in the problem situation. Following from these results, reformulation strategies and reformulated problem examples were developed that would include the Identifying variables stage. These reformulated problem examples were then applied to a 7th grade classroom as a case study. From this case study, it is shown that: (1) the reformulated problems that included authentic events and questions would encourage students to better engage in understanding the situation and solving the problem, (2) the reformulated problems that included the Identifying variables stage would better foster the students' understanding of the situation and their ability to solve the problem, and (3) the reformulated problems that included the mathematical modeling process could be applied to lessons where new mathematical concepts are introduced, and the cooperative learning environment is required. This research can contribute to school classroom's incorporation of the mathematical modeling process with specific reformulating strategies and examples.

Purpose: The aim of this study was to investigate the effects of coordinative locomotor training in a chronic stroke patient. Methods: A left hemiplegic patient diagnosed with a right middle cerebral artery stroke participated in this research. The patient's functional conditions were assessed, and a coordinative locomotor training program was initiated to resolve the problems identified. A set of movements deemed difficult based on the brief International Classification of Functioning, Disability and Health core set for stroke and d4501 (long-distance walking) were agreed as improvement targets. The program comprised warm up, main, cool-down, and home exercises. Repeated measurements were obtained, as follows: five times at baseline (A), 10 times during the intervention (B), and five times after the intervention (A). The study period was 7 weeks, and the intervention period was 1 h per day, twice a week for 5 weeks. Various tools, including the community walking test (CWT), 10-m walking test (10 MWT), 6-min walking test (6 MWT), and timed up and go (TUG) test, were conducted to assess the patient's walking ability. Changes in functional domains before and after the ICF Qualifier were compared. The mean values of the descriptive statistics were calculated, and a visual analysis using graphs was used to compare the rates of change. Results: The results showed that the CWT, 10 MWT, 6 MWT, and TUG test scores during the intervention period improved and that this improvement remained, even during the baseline period. In addition, the ICF Qualifier before and after the comparison decreased from moderate to mild. Conclusion: Based on the results, we propose that coordinative locomotor training can have positive effects on community ambulation of chronic stroke patients.

HERBA SAURURI (HS) has been known to use antiinflammatory drug. To investigated the mechanism of HS-induced NO synthesis, I evaluated the ability of protein kinase C (PKC) inhibitors such as staurosporine (STSN) or polyymyxin B to block HS-induced effects. HS alone had only a small effect, whereas in combination with $rIFN-{\gamma}$, markedly increased NO synthesis in a dose dependent manner. STSN and polymyxin B decreased NO synthesis, which had been induced by $rIFN-{\gamma}$, plus HS. Furthermore, prolonged incubation of the cells with phorbol ester, which down-regulates PKC activity abolished synergistic cooperative effect of HS with $rIFN-{\gamma}$ on NO synthesis. STSN and Polymyxin B potently inhibited HS-induced $TNF-{\alpha}$ secretion by $rIFN-{\gamma}$ plus HS. However, $rIFN-{\gamma}$ plus $TNF-{\alpha}-induced$ NO synthesis was not blocked by STSN or polymyxin B. On the other hand, tyrosine kinase inhibitor, genistein, blocked the NO synthesis and $TNF-{\alpha}$ secretion by $rIFN-{\gamma}$ plus HS. In conlusion, the present results strongly suggest that the capacity of HS to increase NO synthesis from $rIFN-{\gamma}-primed$ macrophages is the result of HS-induced $TNF-{\alpha}$ secretion via the signal transduction pathway of PKC and tyrosine kinase.

The rapid development of internet information technology has increased interest in e-Trade these days, but it is not activated greatly up to now. In order to promote e-Trade, it is essential to construct cooperative process such as connecting systems among trade related parties. Building e-Trade platform which is based on the infrastructure of the past trade automatic system is key point of promoting e-Trade. To do this, a study on the basic concept and specific components of e-Trade platform is needed absolutely. At this point of view, after this paper has examined domestic and foreign studies on the fundamental technologies about electronic commerce, it drew several key technologies that could be applied to e-Trade considering the current IT trend. Then it evaluates these technologies according to Technology Reference Model(TRM) of the National Computerization Agency. This will help us to show the operation strategy as well as the concept of future e-Trade platform and its composition. On the basis of the theoretical background, this paper classified NCA's technology model into 6 fields, which are application. data, platform, communication, security and management. Considering the key technologies, e-Trade platform has to be mutually connected and accept international standards such as XML. In the aspect of business side, trade relative agencies' business process as well as trading company's process has to be considered. Therefore, e-Trade platform can be classified into 3 parts which are service, infrastructure and connection. Infrastructure part is compared of circulating and managing system of electronic document, interface and service framework. Connecting service (application service) and additional service (application service) consist of service part. Connecting part is a linking mutual parts and can be divided into B2B service and B20 service. The organization operating this e-trade platform must have few responsibilities and requirements. It needs to positively accept existing infrastructure of trade automatic system and improving the system to complete e-trade platform. It also have to continuously develop new services and possess ability to operate the system for providing proper services to demanders. As a result, private sector that can play a role as TTP(Third Trust Party) is adequate for operating the system. In this case, revising law is necessary to support the responsibility and requirement of private sector.

Purpose: The purpose of this research was to evaluate the application of the Problem-Based Learning(PBL) in nursing with regard to the learning process and learning outcomes. Method: PBL modules were provided to the students so that they could identify the nursing problems related to nutrition, regulation, and elimination, and implement appropriate nursing interventions according to the problems. PBL was also used to develop ability to use self-evaluation for nursing intervention outcomes. The modules were developed by the authors for the course, Nursing 1(3 credits) at Y university, and used during one semester, March to June 2003. Evaluation of the learning process and learning outcomes was done by self-report questionnaires and a semi-structured self -report developed by the authors. Result: The PBL evaluation included role of the facilitators, group work process, and self-directed learning attitude. The students evaluated the facilitator's role positively in fostering positive interactions and cooperative study among students and stimulating students to apply various problem-solving strategies. Students evaluated their own group work performances as a good opportunity to improve their group work participation, contribution, cooperation, and leadership through the PBL session. Their responsibility for their own learning and develop self-directed learning attitudes to connect present learning to long-term goals. Conclusion: Critical thinking, problem solving skills, self-directed learning and group work accomplishments in undergraduate student nurses were fostered and improved through the PBL program.

Efficiency and competitive power in agribusiness management has became important issue due to the rapid changes in farming environment under new WTO agreement. To increase competitive power, small-sized petty farm should be restructured to be specialized large-scaled farming system. Trust farming corporation(TFC) has been introduced to increase farm productivity and competitive power through large scale farming system and refined management skills. Eventually, TFCs are expected to revitalize rural economy. TFCs are increasing in numbers, but they are unsatisfactory in quality often with insolvent operations. The typical problems with TFCs are internal conflicts among members, lack of management abilities and incentives, inefficiency in machinery use, and insolvent operations. The self effort by members and legal-institutional assistance can alleviate the negative factors against the rational for cooperative management and sustain TFCs. This study identifies the management problems of TFCs. To provide the methods for increasing management efficiency, improving rational management skills, and hence to help revitalizing the rural economy with competitive power, 20 TFCs in Nonsan County is surveyed. The major findings are as follows; 1) According to the survey result of 20 trust farming corporations, investments on the accumulation of knowledges and information, accounting management, machinery management are required due to the present lack of management/accounting ability. There also exist problems associated with revenue sources, labor uses, and public recognition. To increase management efficiency under current situation, corporations should import active business plans with expanding farming execution and off-farm season business. 2) Based on the result of corporations' business analysis, more than 50% of the corporations were not able to provide profit dividends to the members. It suggests that trust farming corporations need appropriate and stable revenue sources to sustain business. It is also required that corporations should reduce their excessive expenditure on fixed assets. 3) Theoretical amounts of consignment fees for tillage operation, planting, and harvesting were found to be 338,874 won, 216,596 won, and 332,318 won, respectively. Although actual levels of fee are 110%~120% of these theoretical levels of consignment fee, corporations' expected fee levels could not be acheived because of competency of consignment market.
