Anterior Cruciate Ligament (ACL) plays an important biomechanical role for the stability of knee joint. ACL injury often leads to injuries of articular cartilage, menisci, or other supporting structures, and subsequent development of degenerative arthritis. Controversies still exist in the best treatment modalities of ACL injuries. hut the author considers it most important to make the appropriate patient selection for operative reconstruction or nonoperative treatment. and describes the treatment principles of ACL injury, including diagnosis, patient selection and the treatment modalities for successful treatment of ACL injury.

The main purpose of this study is that financial resources allocation criteria are examined closely between central government and local government as well as among local government in a river basin. Financial resources allocation principles reflecting water use, flood control, and water quality improvement are reviewed and derived two categories such as common factors and individual factors. The weights of each factor are assigned by analytical hierarchy process. The results of applying four river basins (Han river, Geum river, Nakdong river, Yeongsan-seumjin river) show that rational raising of financial resources are different according to the characteristics of each river basin. Findings are as follows: In case of Han river and Yeongsan Seumjin river, benefit principle and polluter pay principle by individual factors are more attractive than other Principles. Solvency principle by common factor is more acceptable than the other principles in Nakdong-river and Geum-river.

This study aims to find the major creative ideation patterns embedded in the commercially valuable patents in the mobile communication industry. For the purpose, we analyze 171 cases of the patent infringement lawsuit filed by Nokia in the United States. It is examined that what kind of TRIZ inventive principles and SIT thinking tools were applied to resolve technical contractions in each of the 171 cases respectively. Among the 40 inventive principles of TRIZ, 'feedback' principle was used mostly and 'division' principle the next. Among the 5 thinking tools of SIT, 'attribute dependency' mostly used, and 'division' the next. This suggests that what kind of inventive principles or thinking tools should be considered preferentially to resolve technical contradictions in practically important technical problems in the mobile communication industry.

TRIZ was developed and refined in the Soviet Union between 1946 and 1985 by Genrich Altshuller. Its primary application has been for solving inventive problems in the areas of engineering. But, recently the elements of TRIZ began to be applied non-technical areas by Darrell Mann. TRIZ theroy was brought into South Korea in 1995 and it is used by the LG, SAMSUNG, POSCO. TRIZ is simply not the tool for technical problem solving, covering many areas of comprehensive approach is being recognized. TRIZ is a methodology for defining problem, finding root cause through RCA(Root cause analysis), defining technical contradiction and physical contradiction. TRIZ overcomes contradiction and purses problem solving method through innovation. TRIZ is a problem solving method in this study using the principles of non-technical fields applied to the improvement of the logistics area study. The method to overcome contradiction is 40 principles. It is possible to generate idea by using 40 principles. This study was applied to logistics field of non-technical area by using TRIZ principle.

A creative innovation and an innovative problem-solving of industrial companies can be achieved by overcoming the challenges of technical and physical contradictions. The approaches to address conflicting and paradoxical problems, such as technical and physical contradictions have a crucial role in advancing the quality assessment for manufacturer and service provider. The term, technical contradiction, depicts the state that improvement of one ends of IFR (Ideal Final Result) leads to unfavorable condition of the other ends, and results in conflicting problem. Another type of contradictions that's discussed in this study is a physical contradiction which is due to two mutually opposing states of the means of ends, and gives paradoxical situation. By integrating the means-ends chain perspectives, the physical contradiction that is a specifically root-causes, "means", can be initially addressed to resolve the downstream problem of technical contradiction which represents a general and abstract goals, "ends". This research suggests IFR resolution processes to handle both physical contradiction of means and technical contradiction of ends by employing causal relationship with IFR, effects and causes. In summary, the study represents three major processes that resolve such contradictions are demonstrated as follows: 1) Derivation of causal and hierarchical relationship among IFR, ends and means by considering CAED (Cause-And-Effect Diagram) and LT (Logic Tree). 2) Identification of causal relationship between physical contradiction and technical contradiction by using TPCT (TRIZ Physical Contradiction Tree) and TCD (Technical Contradiction Diagram). 3) Application of integrated TRIZ principles by classifying 40 inventive principles into 4 general conditions of the separation principle of mutually opposite states in space, in time, based on conditions, and between the parts and the whole. In order to validate the proof of proposed IFR resolution processes, the analysis of the TRIZ case studies from National Quality Circle Contest in the years, 2011 to 2014 have been proposed. The suggested guidelines that are built based on TRIZ principles can uniquely enhance the process of quality innovation and assessment for quality practitioners.

Objectives: Agent Orange TCDD has been related to serious diseases among Korean veterans who were exposed to it. Decades after the end of the war, however, its effects are still being debated. The object of this study was to examine various unmet needs raised among Agent Orange exposed veterans and their families and to find grounds of a new welfare policy for providing alternative legislation. Methods: Literatures concerning Agent Orange, TCDD, the associated diseases, compensation for veterans and Supreme Court sentencing were searched using PubMed, ProQuest, press news and relevant homepages. Results: Agent Orange exposed veterans are eligible for various benefits from the government, including disability compensation for diseases associated with exposure. The Ministry of Patriots and Veterans Affairs has classified certain diseases into two categories, Agent Orange sequela diseases and sequela suspect diseases and has provided differential benefits based on separated laws. Big differences exist in benefits to veterans and their families between the two laws. The absence of definite standards to classify the Agent Orange associated diseases was confirmed by recent Supreme Court sentencing which ruled in favor of US manufacturers. Conclusion: It appears that the evidence for cause and effect of Agent Orange related diseases would never be perfect. The results suggest a need to change welfare principles from presumptive or indefinite disease basis to exposure experiences combined with integrated disability evaluation. We propose to extend eligibility by enacting a new law for Agent Orange exposed Korean veterans.

The amendment of regulation affecting the Governing Body of NFFC (National Federation of Fisheries Cooperatives) has been known to the public in May 2008. Its essential points are as follow: 1) the President of NFFC shall be a non-standing officer. 2) the Full-Time Directors shall have the authority to deal with all subjects except for those especially reserved for the General Meeting or Board of Directors, while minimizing the authority of NFFC President. By providing this amendment, the government seeks to make the Governing body becomes professionalized and the management functions carried out by full-time professional board members. However, the amendment seems to pay no attention to the co-operative's identity and principles. In this context, five issues will be discussed: 1) Strengthening the separation between ownership and control of NFFC. 2) Weakening the authority of General Meeting. 3) The bounds of Audit Committee. 4) Consolidating the management control of the Full-Time Directors. 5) The loss of NFFC's Identity, followed by a summary and conclusion.

The biological activity of monoglycerides, diglycerides, triglycerides and free fatty acids were investigated by the rice inclination test that is specific bioassay for brassinosteroids. The experimental results revealed that some diglycerides, triglycerides and free fatty acids as well as monoglycerides showed positive response. ${\alpha}-Monoolein$ and diolein as active principles showed higher activity than indole-3-acetic acid at the same concentration. From the results, it can be confirmed that the active principles are related to olein which especially have a high activity.
