  • Recently, US NRC revised fracture toughness requirements as 10CFR50.61a to reduce the conservatism of 10CFR50.61. However, unlike previous studies relating to the initial regulation, structural integrity evaluations based on the alternative regulation are not sufficient. In the present study, PTS and P-T limit curve evaluations were carried out by using both regulations and resulting data were compared. With regard to the PTS evaluation, the results obtained from the alternative requirements were satisfied with the criterion whereas those obtained from the initial requirements did not meet the criterion. Also, with regard to the P-T limit curve evaluation, operating margin by 10CFR50.61a was greater than that by 10CFR50.61.

  • The purpose of this paper is to increase the competitiveness of firms by establishment of green marketing strategy and its application to a new alternative energy development, ultimately contributing to the advancement of national economy. This study adopted an integrated approach to develop a strategic theory of 'Sun Tzu on the Art of War' that is one of the oldest military treaties and still applicable to today's management development. It applies to the empirical result from a new alternative energy development. For more qualitative improvement of this paper, it needs further detailed studies in both theory and practice in green marketing theory that is applicable to the new alternative energy development.

  • This paper presents that in the Russian Revolution 1) socialist and alternative democratic conceptions between Marx and Lenin are very different, 2) the process and cause of failure of realizing Lenin's democratic alternative conception, 3) the interactive expansion process of the party and the state, 4) the failing process of socialist original accumulation, collectivization, and constructing planned economy. This shows that Russia could not help fail to transit to socialist society due to the combination of wrong conceptions and that new revolution and construction should combine right socialist and democratic conceptions.

  • The aim of this study is to develop a model for the alternative selection in port privatization using Brainstorming, the ISM and AHP methods. For this, 30 detailed attributing factors were identified by both previous studies and port users, Also, 13 attributing evaluation factors were identified by a group of port experts using the brainstorming method. These were made into a model of hierarchical structure with 3 levels, taking 1 goal factor, 5 evaluation factors and 7 alternative factors using the ISM method. The collected date of questionnaires through the AHP method were analyzed with a group of port experts for an empirical analysis. The result of the hierarchical level 2 shows that profitability is the most important factor, followed by public interest, management professionality, service quality and financial soundness. The analysis results of hierarchical level 3 shows that commercialization is the most important factor.

  • Competency means 'the ability to do something', and competency-based education means 'the process of education based on the concept of competency'. Competency-based education is generally implemented in general education. However, competency-based education has not yet been actively conducted in the field of Christian education. In particular, it has not been established academically on what competencies Christian alternative schools provide in common. Most of the previous studies related to competency-based education in Christian education are related to competency-based education conducted by Christian universities. Research related to competency in Christian alternative schools is mainly related to the professionalism of teachers or the ideology of Christian alternative schools. In other words, there are few specific studies on what kind of competency they provide to students attending Christian alternative schools. Therefore, this study aims to understand the reality of competency-based education conducted by Christian alternative schools using Delphi analysis techniques. Through this study, four goals and 20 competency elements of competency education pursued by Christian alternative schools were found. By categorizing the goals and elements of competency education, it can be divided into relationships with God, relationships with oneself, and relationships with others and the world. In conclusion, it was suggested that Christian alternative schools should provide education that pursues the universal purpose of Christian education based on specificity and reflect the goals and elements of competency education in the curriculum.

  • Objectives Korea's Act on the Registration and Evaluation of Chemicals (K-REACH) was enacted for the protection of human health and the environment in 2015. Considering that about 2000 new substances are introduced annually across the globe, the extent of animal testing requirement could be overwhelming unless regulators and companies work proactively to institute and enforce global best practices to replace, reduce or refine animal use. In this review, the way to reduce the animal use for K-REACH is discussed. Methods Background of the enforcement of the K-REACH and its details was reviewed along with the papers and regulatory documents regarding the limitation of animal experiments and its alternatives in order to discuss the regulatory adoption of alternative tests. Results Depending on the tonnage of the chemical used, the data required ranges from acute and other short-term studies for a single exposure route to testing via multiple exposure routes and costly, longer-term studies such as a full two-generation reproducibility toxicity. The European Registration, Evaluation, Authorization and Restriction of Chemicals regulation provides for mandatory sharing of vertebrate test data to avoid unnecessary duplication of animal use and test costs, and obligation to revise data requirements and test guidelines "as soon as possible" after relevant, validated replacement, reduction or refinement (3R) methods become available. Furthermore, the Organization for Economic Cooperation and Development actively accepts alternative animal tests and 3R to chemical toxicity tests. Conclusions Alternative tests which are more ethical and efficient than animal experiments should be widely used to assess the toxicity of chemicals for K-REACH registration. The relevant regulatory agencies will have to make efforts to actively adopt and uptake new alternative tests and 3R to K-REACH.

  • This Study is divided into 5 separate Parts and an Abstract. Part Ⅰ, Ⅱ consist mostly of a collection of problems, current status, motives and the future of ADR. In Pert Ⅲ was described ADR as policies of judicial settlements. We must accept that a diversity of legal culture will always continue to exist. Accordingly we must learn to accommodate those differences of 'culture' around us and to harmonize conflicting laws. This recognition of our reality should in no way be confused with pessimism. In fact if one accepts this perspective of the world ,the study of law seems enriched and becomes academically more challenging. Recently, in the United States, interest in alternative settlement mechanism has increased greatly, which leads me to wonder why such a phenomenon has taken place. In the first place, I'm amazed at the extent to which conciliation or mediation-or the new word, I guess, is alternative dispute resolution, which by now has its own acronym, "A.D.R,"-have gained attention here recently. When 35 years ago, there was virtually no interest in conciliation in this country at the time. What interest there was, was no in the law schools. But looking at the situation now, we have a spate of publications on the subject; we have organizations that are established for no other reason than to promote alternative dispute settlement. We have courses in the law schools. The American Association of Law Schools and the American Bar Association also have active programs. So we have to ask ourselves why. The difference between now and 35 years are striking. On the other hand, I think the interest of the public in ADR has probably been greatly enhanced by the politics of the so-called "poverty programs." I think that many of these assistance programs for the poor-and I do think the "poor" have become a rather expansive political movement beyond simply taking care of the most marginal people of society-have generated money to explore this kind of dispute resolution.

  • Alternative splicing is an important process in gene expression. Alternative Splicing can lead to mutations and diseases. Most studies detect alternatively spliced genes with ESTs (Expressed Sequence Tags). However, reliance on ESTs might have some weaknesses in predicting alternative splicing. ESTs have been stored in the libraries. The EST libraries are often not clearly organized and annotated. We can pick erroneous ESTs. It is also difficult to predict whether or not alternative splicing exists for those genes where ESTs are not available. To address these issues and to improve the quality of detection and prediction for alternative splicing, we propose the One-leaf One-node Tree Algorithm that uses pre-mRNAs. It is achieved by codons, three nucleotides, as attributes for each chromosome in Arabidopsis thaliana. The proposed decision tree shows that alternative and normal splicing have different splicing patterns according to triplet nucleotides in each chromosome. Based on the patterns, alternative splicing of unlabeled genes can also be predicted.

  • This study is to propose a alternative gem that is expressed in various ways instead of jewelry with limited output. It was investigated what materials were used in the alternative gem used in the jewelry design thesis over the past five years. In addition, as a result of a survey to understand the needs of customers, it was found that customers also use resin among resins as an alternative gem, like as research trends. Based on this, the scope of resin use as a alternative gem was expanded and applied to jewelry design rather than the existing method of using resin. As a result, it was found out a various uses of resin as an alternative gem. However, the demand and traditionality that correspond to the conditions of jewelry remain challenges to be established through various jewelry design studies in the future. Therefore, in order to utilize the popular preference of alternative gem, continuous research on applying jewelry design to alternative gem should be continued.
