Recently, many firms have been more interested in how the competitiveness of the supply chain can be enhanced, rather than that of the respective company. The purpose of this study is not only to investigate the relationships among the trust between companies, the supply chain integration, and the supply chain performance, but also to demonstrate how the firm size and the absorptive capacity can moderate these relationships. To conduct the hypothesis test including the causal relations between two factors and the moderating effects, 111 data were collected through a survey. As a result, the supply chain performance was positively affected by the supply chain integration as well as the trust between the companies. In addition, the trust had a significant effect on the supply chain performance. The result of the moderating effect of firm size indicates that, compared with a larger group, a smaller group has a stronger relationship between the trust and the supply chain performance, while the relationship between the supply chain integration and the supply chain performance is much stronger in the large group than the small group. As for the moderating effect of absorptive capacity, a higher absorptive group has stronger relationships between the trust and supply chain integration, and supply chain integration and supply chain performance than a lower absorptive group. The findings would provide significant implications for supply chain partners with different sizes and absorptive capacity.

The amount and diversity of information is increasing, as is the information integration connecting data among the related institutions. In the defense field, DTAQ, which is in charge of the quality of military supplies, is attempting to collect and analyze the information which is related with it. In addition, the object of information integration is to expand civil data as well as defense data. There are many ways to integrate data in various environments. In the defense field, which needs enhanced security, it is necessary to establish and apply the information integration methods which are enhanced with more security. In this study, the framework and architecture of information integration was designed by considering task requirements and security conditions. As a result of example application of this framework for information systems to the selected 4 institutions, it was confirmed that the task can be performed through data connections. From the study result, integration architecture which can be applied securely in defense field was suggested. The data accumulated by using this framework with strengthened security are expected to be utilized for the quality improvement of military supplies.

Objective : The aim of this study was to determine the priority competency by analyzing the importance, performance, and educational requirements of occupational therapists to develop a competency in performing sensory integration intervention. Methods : Occupational therapists were surveyed by gender, age, educational background, work location, occupational therapy experience, and sensory integration therapy experience. The difference was investigated through the importance-performance analysis of competency, and the priority of the competency was investigated using the Borich demand analysis method. Results : The therapists recognized professional competency as the most important, whereas performance was the least important. In all sub-competencies, the importance was high, but the performance was low. As a result, the education requirement was highest for professional competency. The importance-performance analysis revealed that professional competency was the area requiring the most urgent improvement. As a result of the Borich demand analysis, statistically significant differences between the importance of all competencies and the actual performance. The most significant difference was found in the professional competency group. Conclusion : The occupational therapists in this study who performed sensory integration interventions recognized professional competency as the most important but most lacking in actual clinical practice. The results of this study will be used as guidelines for developing competency-based sensory integrated intervention curricula.

Objective : This study aimed to summarize and present the effects of group sensory integration treatment applied to children with and without disabilities in Korea. Methods : The search period was from January 2010 to December 2021, and databases of 'The Journal of Korean Academy of Sensory Integration', 'The Korean Journal of Occupational Therapy', 'Koreanstudies Information Service System', 'Research Information Sharing Service', 'DBpia' were used for data search. A total of 11 studies were selected, and the Patient, Intervention, Comparison, Outcome method was applied to organize them systematically. Results : As a result of the study, single-group non-randomized studies were the most common with 8 out of 11 studies (72.73%). There were 99 subjects, ranging in age from 3 to 11, and an average of 7.39. Among them, there were more children with disabilities, and 40 out of 99 (40.41%) were diagnosed with developmental disabilities the most. A total of 5 to 45 treatment intervention sessions were provided, and 60 minutes were the most frequently provided once or twice a week. The Canadian Occupational Performance Measure and The Penn Interactive Peer Play Scale were the most commonly used evaluation tools in 4 times each (12.90%). As the treatment intervention goal, social interaction skills was the most common with 8 studies (36.36%). As a result of treatment intervention, 8 studies showed significant results. Conclusion : Based on this study, it is expected that in the future, various methods of intervention of sensory integration therapy based on high quality levels can be systematically presented and used as useful information in clinical practice.

Why solar companies preferred vertical integration of whole value chain? Major solar companies have built internally strong vertical integration of entire PV value chain. We raise a question whether such integration increases the corporate value and whether market situation affects the result. To test these questions, we conducted multi-variant analysis where characteristic factors mainly affect the corporate value measured in terms of Tobin'Q, based on the financial and non-financial data of PV companies listed in US stock market between 2005 and 2010. We hypothesize that since integration increases the overall efficiency but decreases the flexibility to adjust to various market situation, the combined effect of the efficiency gain and the flexibility loss ultimately determines the sign of integration effect on the corporate vale. We infer that the combined effect will be influenced heavily by business cycle, as in boom market (Seller's market) the efficiency gain may be larger than the flexibility loss and vice versa in bust market. We test whether the sign of combined effect changes after the year of 2009 and which factors influence most the sign. Year of 2009 is known as the year when market shifted from Seller's to Buyer's market. We show that 1) integration increases corporate value in general but after 2009 integration significantly decreases the value, 2) the ratios such as Production/Total Cost, Cash turnover period chosen for reversal of the flexibility measure are negatively affect Tobin's Q and especially stronger after 2009. This shows the flexibility improves corporate value and stronger in the recess period (Buyer's market). These results imply that solar company should set up integration strategy considering the tradeoff between efficiency and flexibility and the impact of the business cycle on both factors. Strategy only based on the price competitiveness determined in boom time can bring undesirable outcomes to the company. In addition, Strategic alliances in some value chains as a flexible bondage should be taken in account as complementary choice to the rigid integration.

A family of the structure-dependent methods seems very promising for time integration since it can simultaneously have desired numerical properties, such as unconditional stability, second-order accuracy, explicit formulation and numerical dissipation. However, an unusual overshoot, which is essentially different from that found by Goudreau and Taylor in the transient response, has been experienced in the steady-state response of a high frequency mode. The root cause of this unusual overshoot is analytically explored and then a remedy is successfully developed to eliminate it. As a result, an improved formulation of this family method can be achieved.

Sensitivity analysis scheme is developed in the elasto-plastic finite element method with explicit time integration using direct differentiation method. The direct differentiation is concerned with the time integration, constitutive relation, shell element with reduced integration and the contact scheme. Sensitivity analysis results are mainly examined with the highly nonlinear and quasi-static problem with the complicated contact condition. The result shows stable sensitivity especially in the sheet metal forming analysis.

Objectives: In Korea, there are many kinds of evaluations for medical institutions. However, evaluations are increasingly burdensome for medical institutions because evaluation agencies, evaluation timing, and evaluation methods are different. The purpose of this study is to improve the efficiency of evaluation for medical institutions and ultimately to provide quality medical services to patients. Methods: In this study, 2,310 indicators of 19 kinds of evaluation for medical institutions were analyzed. Results: 1,424 indicators were available for on-site surveys and 886 indicators were not available for on-site surveys. There were 4 kinds of evaluation that can be integrated in total, 12 kinds of evaluation that can be integrated partially, and 3 kinds of evaluation that need to maintain the current evaluation system. Conclusion: In order to provide patient-centered quality medical services through reduction of burden due to the evaluation for medical institutions, it is necessary to deeply discuss the efficiency of evaluation integration and result utilization.

A competitive automated manufacturing system integrates the various control processes and data used in service of products. design, manufacturing, and, sale. CIM is a way to achieve such integration through computers and computational techniques in manufacturing, planning, and design. Developing effective CIM architectures is hampered by integration problems. The key to resolving these problems lies in a better understanding of manufacturing function and how it is related to other manufacturing functions. Integration of CIM environment requires coordinated solutions to data management problems for individual application system as well as for exchange of data between these applications. This requires a common framework for data management throughout the CIM environment. This paper discusses the design paradigm as a framework for this purpose. Designing an organizational structure to meet those goals invloves 1) analyzing the functions through functional decomposition, 2) developing a data model to coordinate functions. As a result, we propose an object-oriented design methodology for manufacturing information system.
