We study emotion regulation in a distant CABLe (Collaborative Argumentation Based-Learning) setting at university. We analyze how students achieve the group task of synthesizing the literature on a topic through scientific argumentation on the institutional Moodle's forum. Distinguishing anticipatory from reactive emotional regulation shows how essential it is to establish and maintain a constructive working climate in order to make the best out of disagreement both on social and cognitive planes. We operationalize the analysis of anticipatory emotional regulation through an analytical grid applied to the data of two groups of students facing similar disagreement. Thanks to sharp anticipatory regulation, group 1 solved the conflict both on the social and the cognitive plane, while group 2 had to call out for external regulation by the teacher, stuck in a cyclically resurfacing dispute. While the institutional digital environment did afford anticipatory emotional regulation, reactive emotional regulation rather occurred through complementary informal and synchronous communication tools. Based on these qualitative case studies, we draw recommendations for fostering distant CABLe at university.

Digital textbooks draw attention as a new format of educational material, using the advantages of information technology; this innovative learning tool requires consideration as a part of successful and effective learning. The main purpose of the article is to investigate the mediating role of self-regulation between digital literacy and learning outcomes (academic performance and learning motivation) when using digital textbooks as a learning tool in Middle School English. Both descriptive and regression analysis were used as data analyses methods. The main findings of this study were as follows: first, digital literacy and self-regulation significantly predicted academic performance and learning motivation; second, self-regulation fully mediated between digital literacy and academic performance; third, self-regulation partially mediated between digital literacy and learning motivation. The research results proved the effects of digital literacy and self-regulation on the learning outcomes and mediating role of self-regulation between digital literacy and learning outcomes. These results help to design and implement effective lessons when using a digital textbook in Middle school English.

Collaborative learning encourages the use of high-level cognitive strategies, critical thinking, and interpersonal relationships. Despite these advantages, most instructors reveal the difficulties of using project-based collaborative learning; a common problem is the failure of the group to work effectively together. Thus, this study attempted to provide practical advice on group composition with self-regulation. In a college course, 31 groups with 129 students were asked to discuss and prepare the final presentation material and present it together as a collaborative work. All students' self-regulation skills were measured at the beginning of the semester, and the collective self-regulation was computed as an average of the individual scores of each group. The results of regression analysis indicate that the group's collective self-regulation shows a highly significant positive effect on group performance and satisfaction, as self-regulation predicts individual academic performance. The results also show that there is a significant positive relationship between students' self-regulation and participation in group work.

Korea Shipping Act admits shipping conferences' joint actions like rate agreement, sailing agreement in some degree for development of shipping transport industries for decades. Meanwhile, EU has prohibited all kinds of shipping conferences' joint actions since October 2008, and many advanced countries also have similar position on shipping conference. The balance development between shippers and ship owners is very important in terms of national economic growth. So it is appropriate time to revise related laws such as Shipping Act and Monopoly Regulation and Fair Trade Act. First, It is direction for revision of Korean Shipping Act. The act has to define precisely the criteria of "unfairness" in case of admitting of shipping conferences' joint actions. Shipping conferences have a conference with shipper or shipper's delegation substantially on freight and transport conditions and so on. Second, It is direction for revision of Monopoly Regulation and Fair Trade Act. The fair trade commission has to perform fair roles between shippers and ship owners. The judgement of fairness has to confirm according to the spirit of not Korea Shipping Act but Korea Monopoly Regulation and Fair Trade Act itself.

In 2006, as a means to minimize early corrosion failure of ships, thus to enhance marine safety, International Maritime Organization (IMO), proposed a mandatory regulation for Performance Standards for the Protective Coatings (PSPC) for ballast tanks of newly built ships to satisfy 15 years of target useful life. In this regulation, several unprecedented strict rules are adopted as minimum, mandatory requirements for protective coatings of ship's water ballast tanks, and all type of ships sailing international sea are subjected to this regulation which is to be effective as early as June of 2008. The PSPC addresses many technical issues in the areas of surface pretreatment (primary and secondary), coating materials, coating application procedure and inspection as well as necessary documentation. The PSPC rules are new and unproven concepts, which calls for rigorous incorporation of reality-based evidences currently available, since there are no practical experiences in terms of the validity of the PSPC rules. There has been much controversy surrounding these regulations and considerable effort has been made by both shipyards and ship owners alike to achieve a performance standard for ballast tank coatings, which is acceptable to all. In this paper, the background and overview of the PSPC rules are given, and several issues in the PSPC are reviewed as a base to achieve robustness of the proposed PSPC, which will serve as a means to minimize early corrosion and to ensure 15 year target useful life of ships.

Climate change is one of the biggest dangers facing all living creatures in the earth. It has been understood that emissions of greenhouse gases from human activity is the cause of climate change. Cars are responsible for around 12% of total EU emissions of CO2, the main greenhouse gas. The United Nations Framework Convention on Climate Change (UNFCCC or FCCC) is an international environmental treaty adopted at the United Nations Conference on Environment and Development (UNCED) on 9 May, 1992, which entered into force on 21 March 1994. The European Commission first adopted a Community Strategy to reduce CO2 emissions from cars in 1995. On 19 December 2007, the European Commission proposed "Proposal for Setting emission performance standards for new passenger cars to reduce CO2 emissions", which was adopted on 23 April 2009 as "Regulation (EC) No 443/2009". Prior to submitting the Proposal, the European Commission performed impact assessment and prepared impact assessment report which was reviewed by the Impact Assessment Board. The objective of this Regulation is to set emission performance standards for new passenger cars registered in the Community, which forms part of the Community's integrated approach to reducing CO2 emissions from light-duty vehicles while ensuring the proper functioning of the internal market. In the event that a manufacturer fails to meet its target, it will be required to pay an excess emissions premium in respect of each calendar year from 2012 onwards. On 11 March 2014, Regulation (EC) No 333/2014 amending Regulation (EC) No 443/2009 was adopted. Regulation (EC) No 333/2014 amends Regulation (EC) No 443/2009 to implement the modalities of meeting the 95g CO2/km target for new passenger cars to be reached in 2020. As industry benefits from indications of the regulatory regime that would apply beyond 2020, the Regulation includes a further review to take place by, at the latest, 31 December 2014.

범세계 해상 조난ㆍ안전 시스템에 따라 이의 한 요소인 위성 EPIRB는 국제항해에 종사하는 300GT 이상의 모든 선박에 의무적으로 탑재해야 할 뿐 아니라 각국의 자국법에 의해 어선과 같은 소형선에서도 위성 EPIRB 탑재를 확대 보급되고 있는 추세이다. 그러나 이를 규제하고 있는 현행 국내법으로는 국제법에서 요구하고 있는 위성 시스템과의 호환성 및 장비 자체의 성능을 정확히 평가할 수 없으며 국제법에 준하는 성능 검사가 요구되더라도 일반적인 계측기를 통해서는 확인할 수 없다는 문제점을 안고 있다. 따라서 본 연구에서는 국제법에서 규정하고 있는 대부분의 시험 내용을 확인할 수 있는 시험용 Bench를 설계, 제작하여 기저대역에서 파악하여야 하는 파형에 관련된 사항뿐만 아니라 변조 특성, 주파수 측정, 전력의 측정 등을 쉽게 수행할 수 있도록 하였으며 본 연구의 결과를 통해 전체 시스템과의 호환성과 관련된 송신 반복 주기, 위상 편차, 주파수 안정도 등에 대한 기준을 마련함으로써 결론적으로 조난자의 생명과 직결되는 주요한 조난통신장비의 성능을 향상시키게 할 것이다.
