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 role of principles of minimum uncertainty in dealing with the reconstruction problem of systems with dynamic properties is discussed. The aim of the reconstruction problem, one of two problems addressed by reconstruct ability analysis, is to determine the smallest possible sub-systems by which a given overall system can be adequately represented.

본 연구의 핵심은 유역별 통합관리에 필요한 재원을 중앙과 지방정부 그리고 유역내의 지자체간에 어떠한 기준으로 분담하느냐를 다루는 것이다. 이를 위하여 본 연구에서는 재원의 배분을 유역 내의 이수, 치수, 수질개선에 따른 분담원칙과 이를 현실적으로 적용할 공통기준과 개별기준을 설정하고, 설정된 기준에 대한 가중치를 계층적 의사결정기법을 통하여 산정하였다. 재원분담 방안을 유역별로 적용한 결과, 합리적인 재원의 조달 방법이 유역별로 매우 상이함을 발견하였다. 한강과 영산강 섬진강 유역은 개별기준과 수익자 부담원칙에 충실한 부담금적 성격이 타당한 반면, 낙동강과 금강유역은 공통기준과 부담능력에 충실한 조세적성격의 재원배분이 합리적임을 발견하였다.

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.

TRIZ는 원래 러시아인인 알트슐러에 의해 개발되어 기술 분야의 문제 해결에 활용 되어 왔지만, 최근에는 Darrell Mann에 의해 비 기술 영역에도 적용이 되기 시작하였다. 국내에는 1995년 LG전자에서 최초로 도입하여 현재는 삼성, 포스코 등 많은 기업들이 문제 해결도구로 사용하고 있다. TRIZ 문제 해결 방법은 문제를 정의하고, RCA(Root Cause Analysis)를 통해 근본원인을 찾아내어 기술적 모순과 물리적 모순을 정의 하고 있다. TRIZ는 모순을 극복하는 것이 문제를 해결하는 것이다. 본 연구는 문제 해결 방법인 TRIZ 원리를 이용하여 비기술 분야인 물류 영역의 개선에 적용하고자 하였다. 실제 "L" 기업의 물류 재작업이라는 물류 운영 개선을 하기 위해 TRIZ 방법론 중 RCA(Root Cause Analysis)분석, 모순 정의, 40가지 발명원리를 사용하여 문제 해결을 위한 아이디어 도출 및 적용 하였다. 본 연구는 TRIZ를 비기술 분야에 활용하고자 하는 향후 연구자들에게 도움이 되고자 하였다.

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.

Monoglycerides, diglycerides, triglycerides와 free fatty acids를 대상으로 brassinosteroid검정용 생물검정법인 rice inclination test에 의해 생물활성을 검정하였다. Monoglycerides 뿐만 아니라 diglycerides, triglycerides 그리고 free fatty acids의 일부도 이 생물검정법에 양성을 나타냈다. 활성을 나타낸 물질중 ${\alpha}$-monoolein, diolein은 동일 농도의 indole-3-acetic acid 보다 높은 생물활성을 나타내어 olein 관련물질이 특히 높은 생물활성을 갖는 흥미로운 사실을 확인할 수 있었다.
