The open approach to teaching school mathematics in the United States is an outcome of the collaboration of Japanese and U. S. researchers. We examine the approach by illustrating its three aspects: 1) Open process (there is more than one way to arrive at the solution to a problem; 2) Open-ended problems (a problem can have several of many correct answers), and 3) What the Japanese call 'from problem to problem' or problem formulation (students draw on their own thinking to formulate new problems). Using our understanding of the Japanese open approach to teaching mathematics, we adapt selected methods to teach mathematics more effectively in the United States. Much of this approach is new to U. S. mathematics teachers, in that it has teachers working together in groups on lesson plans, and through a series of discussions and revisions, results in a greatly improved, effective plan. It also has teachers actively observing individual students or groups of students as they work on a problem, and then later comparing and discussing the students' work.

I suggested the design learning environment based on affordance concept approach for supporting and improving learners' behavior and outcome for convergent design education in this study. The design learning space should be applied teaching and learning activity, especially learners' behavior, physical space condition to support the design thinking process. The design learning space needs openness, individuality and connectivity to support the learners' behavioral to immerse, participate, cooperate, understand, think and fulfill the design thinking process. The composition principles of the learning environment for convergent design education supports communication and collaboration among members for independence and interaction. The spaces for design research and teaching needs high privacy while facilitating visual communications through special materials and wall structure design. Also, for connectivity to improve the learners' physical and visual contact, the environment of the classrooms requires flexibility and mobility by providing an open space integrating unit cells for realizing learning purpose. These are provided by formed of an open structure for inducing visual communication and physical contact to involve the design activities and the mutual interchange.

There exists historically intimate relationship between the fisheries of the three countries of Northeast Asia in terms of the same fishing ground and similar resources. This means that if one of the countries fail to manage their fisheries properly, it will harm the others. Especially, if the EEZ straddling and Trans-Boundary Fish Stocks aren't managed by the cooperation of the three countries, the exhaustion of resources will be more likely to be accelerated. Considering the aspects mentioned, this paper refers to the necessity of fisheries cooperation between Korea, China, and Japan. Next, it analyzed the joint control cases of Norway/Russia Management of Shared Fish Stocks in the Barents Sea, Management of South Tasman Rise in Orange roughy, Agreement on Fisheries between the European Economic Community and the Kingdom of Norway, Conservation and management of pollack resources in the central Bering Sea, and drew a conclusion for ourselves. Last of all, it suggests a step-by-step strategy of promoting joint control between three countries, and the plan of the establishing and managing the organization of joint fisheries control. About the joint control, "The Joint Statement of promoting collaboration between Korea, China, and Japan" has been announced at ASEAN in October 7th, 2003 and the summit talk of the three countries. In the joint statement, the three countries came to an agreement which says, "Cooperation in Fishery Resource Conservation : The three countries will cooperate, bilaterally or trilaterally, to promote the sustainable use and conservation of fishery resource through the effective fishery management". Not only the consistent collaboration between the government is necessary, but also continuous exchange and related study on a Non-governmental level is also needed for the viable outcome in the near future. When deducting the result for the joint fisheries control, this writer hopes the contents of this study will be helpful.

Component based design is perceived as a key technology for developing advanced real-time systems in a both cost- and time effective manner. Already today, component based design is seen to increase software productivity, by reducing the amount of effort needed to update and maintain systems, by packaging solutions for re-use, and easing distribution. Nowdays, a thousand and one companies in If(Information Technology) industry such as Sl(System Integration) and software development companies, regardless of scale of their projects, has spent their time and endeavor on developing reusable business logic. The component software is the outcome of software developers effort on overcoming this problem; the component software is the way propositioned for quick and easy implementation of software. In addition, there has been lots of investment on researching and developing the software development methodology and leading If companies has released new standard technologies to help with component development. For instance, COM(Component Object Model) and DCOM(Distribute COM) technology of Microsoft and EJB(Enterprise Java Beans) technology of Sun Microsystems has turned up. Component-Based Development (CBD) has not redeemed its promises of reuse and flexibility. Reuse is inhibited due to problems such as component retrieval, architectural mismatch, and application specificness. Component-based systems are flexible in the sense that components can be replaced and fine-tuned, but only under the assumption that the software architecture remains stable during the system's lifetime. In this paper, It suggest that systems composed of components should be generated from functional and nonfunctional requirements rather than being composed out of existing or newly developed components. about implements and accomplishes the modeling for the Product Control component development by applying CCD(Contract-Collaboration Diagram), one of component development methodology, to MRP(Material Requirement Planning) System

We have analyzed technology transfer and commercialization process and factors affecting the outcomes of technology commercialization of public research institutes in Korea. A technology commercialization process model was presented as an input, intermediate outcomes/capabilities, output (outcome) structure using the structural equation model. Input variables include R&D input, technology commercialization strategy/support, collaboration, social capital. The model also includes R&D capabilities and technology commercialization performance as intermediate variable and output variable respectively. The technology commercialization performance was measured as the number of technology transfer and spin-off. We conducted survey and 88 institutes responded. Empirical results show that R&D input influence R&D capabilities and R&D capabilities influence the output of technology transfer and commercialization. Collaboration activities and social capital also appear to have a positive effect on the output. However, the effect of strategy and support on the output appear to be not statistically significant.

This paper will discuss the significance of cooperation between supply chain companies and its components. In addition, it will analyze how this effects the outcome in distribution focusing on companies in the steel pipe industry. In sum, theory 1 was chosen since as a result of hierarchical regression analysis communication, IT, partnership, and success monitoring, which are all components of the supply chain cooperation, are proven to affect the absolute distribution success positively. According to the standardized beta coefficient the most important factor for distribution success is communication, followed by IT, partnership and lastly success monitoring. Moreover, according to theory 2, communication, IT, partnership and success monitoring all affect relative distribution success positively. Most important factors are communication, IT, partnership, success monitoring. Thus, since the most crucial factor in deciding both the absolute and relative distribution success is communication, steel pipe companies are advised to execute strategic use.

Purpose: To evaluate the effects of case management using Resident Assessment Instrument-Home Care(RAI-HC) in home health service for older people. Methods: All elders were assessed at baseline and 3 months later using RAI-HC. The change of function in the intervention group was compared with that of a conventional intervention group. Function was measured with Activities of Daily Living(ADL), Instrumental Activities of Daily Living(IADL), Cognitive Performance Scale(CPS), Depression Rating Scale(DRS), Pain and the number of Clinical Assessment Protocols(CAP). Results: Among ninety two elders participated in the program, 59 were allocated to the case management group and 33 to the conventional group. The intervention, home health service by a nurse over a 3 month period, consisted of comprehensive assessment, case conference for care plan, direct care, education and referral, and outcome evaluation. The percent of elders whose function improved in the intervention group was greater than the conventional group for depression(odds ratio [OR]: 10.941, confidence interval [CI]: 2.338-51.206), IADL(OR: 4.423, CI: 1.151-16.999) and the number of CAP(OR: 11.443, CI: 3.805-34.410). Conclusion: Case management was effective for older people in the community. The effect might have resulted from individual, systematic intervention, however, standards of service including eligibility criteria for case management and collaboration of multi-disciplines is required for more effective home health service programs.

Objectives : This study was designed to investigate the effect of Banhahubak-tang on gastroesophageal reflux disease(GERD) through a systematic review and meta-analysis of randomized controlled trials(RCTs). Methods : RCTs using Banhahubak-tang on GERD was searched in databases such as EMBASE, PubMed, MEDLINE, CENTRAL, CNKI, KISS, RISS, ScienceON, and OASIS. RCTs published up to October 8th, 2021 were included. Meta-analysis was performed by synthesizing outcome data, including Total Effectiveness Rate (TER), Reflux Symptom Index(RSI), Reflux Finding Score(RFS), and Incidence of Adverse Reactions. RevMan 5.4 software was used for data analysis. The Cochrane collaboration bias risk assessment scale was used to evaluate the methodological quality of the included studies. Results : Ten RCTs met the inclusion criteria. The total effective rate was the most commonly used outcome measure. The meta-analysis revealed that the TER in the experimental group was higher than that of the control group(N=2, RR:1.22, 95% CI:1.09 to 1.36, P=0.0004, I²=0%)(N=6, RR:1.22, 95% CI:1.14 to 1.32, P<0.00001, I²=0%)(N=8, RR:1.22, 95% CI: 1.14 to 1.30, P<0.00001, I²=0%). On the other hand, RSI(N=2, MD : -4.29, 95% CI: -4.71 to -3.86, I²=94%), RFS(N=2, MD : -3.28, 95% CI: -3.71 to -2.85, I²=96%), and Incidence of Adverse Reactions(N=5, RR: 0.32, 95% CI: 0.17 to 0.61, I²=0%) in the experimental group were lower than that of the control group. Conclusion : Treatment with Banhahubak-tang was found to be effective on GERD. However the results might be biased because of the poor quality and small sample size of the included RCTs.

Objective: As the demands of healthcare environment change, it is necessary to advance human health care by improving students' essential competencies including knowledge, skills, abilities, inter-professional collaboration and patient centered care. This study identified long term accomplishment and improvement of the essential competencies in clinical pharmacy practice education (CPPE) at Korean hospitals over time. Methods: This study was conducted for pharmacy students who completed CPPE evaluation related to tertiary hospitals and secondary hospitals located in Seoul and Gyeonggi-do regional area from 2014 to 2018. Results: Over the past 5 years, overall results of student evaluation on the essential competencies in CPPE at both tertiary and secondary hospitals showed a decreasing trend or did not change. Essential competency in CPPE at tertiary hospitals had been identified as superior on 'Learn clinical knowledge in the treatment of diseases' to secondary hospitals [average number of students (%): 210 (72.9%) vs 68 (68.0%)]. On the other hand, essential competencies in CPPE at secondary hospitals had been identified as better at 'inter-professionals collaborative teamwork and direct patient care' than tertiary hospitals [average number of students (%): 64 (64.0%) and 56 (56.0%) vs 121 (42.0%) and 90 (31.3%)]. A total of 176 (61.1%) students in tertiary hospitals and 66 (66.0%) in secondary hospitals evaluated that 'patient-centered care' education was good. Conclusion: In tertiary hospitals, all six essential competency outcomes have not been improved, whereas four essential competency outcomes showed an increasing trend in secondary hospitals. It will be necessary to develop outcome-based CPPE education program to better reflect the essential competencies.

Objectives: Designing in situ models for caries research is a demanding procedure, as both clinical and laboratory parameters need to be incorporated in a single study. This study aimed to construct an informative guideline for planning in situ models relevant to preexisting caries studies. Materials and Methods: An electronic literature search of the PubMed database was performed. A total 191 of full articles written in English were included and data were extracted from materials and methods. Multiple variables were analyzed in relation to the publication types, participant characteristics, specimen and appliance factors, and other conditions. Frequencies and percentages were displayed to summarize the data and the Pearson's chi-square test was used to assess a statistical significance (p < 0.05). Results: There were many parameters commonly included in the majority of in situ models such as inclusion criteria, sample sizes, sample allocation methods, tooth types, intraoral appliance types, sterilization methods, study periods, outcome measures, experimental interventions, etc. Interrelationships existed between the main research topics and some parameters (outcome measures and sample allocation methods) among the evaluated articles. Conclusions: It will be possible to establish standardized in situ protocols according to the research topics. Furthermore, data collaboration from comparable studies would be enhanced by homogeneous study designs.
