International Maritime Organization made International Convention for the Safety of Life at Sea to require all ships to carry official charts, both paper and electronic, and is especially encouraging the use of Electronic chart display and information system (ECDIS). Recently, the argument that all Electronic Charts(ENC) displayed in ECDIS should be distributed through Regional ENC Coordinating Center is being raised within the IHO. The use of ECDIS was generalized, but the existing two RENCs in Europe are thought to be not enough. Especially, East Asian region, due to its rapid growth in economy and marine traffic, RENC is found necessary. This research establishes the legitimacy and strategy of East Asian RENC by defining the roles of RENC based on the IMO ECDIS Mandatory Carriage Requirement and RENC operation status through suggesting a "Phase-In" RENC model, which was built upon the strategy of East Asian Hydrographic Commission(EAHC).

According to international regulations, it is mandatory for navigators or engineers to acquire suitable skillsets before their designation as a duty officer on board. One of the most important elements is Maritime English (ME), wherein students are taught a required set of basic skills that enable them to process various documents related to accidents, ship conditions, and inspections. Students have to be equipped not only with the use of general English skills but also with the coherent use of technical terms and phrases. However, due to the unique circumstances that exist in the maritime domain, the methods used for imparting maritime knowledge and the manner in which it is evaluated are restricted. Hence, this study aims to utilize an online Maritime English learning and testing platform that can be accessed on smart devices to analyze its impact on the students' learning process. An experiment was conducted on two groups of cadets, one that used the platform and another group that did not. After six-week, the experiment results showed a significant difference between the ME test scores of the two groups. The test scores were further analyzed by incorporating the students' personal elements to measure the ef icacy of the ME test platform. Therefore, the learning and evaluation processes are expected to be implemented in ways that are appropriate and convenient to specific circumstances and be widely used in the field of maritime education in the future.

Under the regulation of rational energy use in public institutions, it has been mandatory for educational facilities to meet the first grade or higher since 2014. Also the regulation has forced educational facilities as public institutions to use renewable energy since September 2008. Educational facilities are required to be qualified as zero-energy buildings from 2020 under the revision of the Green Building Act. In this study, we identified the current status of the building energy efficiency rating system and the renewable energy system installation for 316 educational facilities that were accredited as "building energy efficiency rating system" from February 2015 to March 2019. Also we analyzed the energy self-sufficiency rate based on energy requirements and renewable energy output. Of the 316 facilities, 12 had 1++ and 293 had 1++ for the "Building Energy Efficiency Rating System". Among the 12 facilities which had 1+++, 11 recorded ZEB level 5 or higher, and 28 out of the 293 facilities(11%) which got received 1++ had ZEB level 5. Thus, it is impossible to implement the ZEB certification system for educational facilities under the present conditions. Expanding the ratio of 1+++ and investing in renewable energy systems should be preceded.

Objectives: To review reference levels by the international and domestic management and provide the basis for setting occupational exposure limits(OELs) of radon in Korea Methods: Government's organizations with laws and systems for monitoring radon exposure were investigated and compared. There are five laws governing Indoor Air Quality(IAQ) control such as Occupational Safety and Health Act, Indoor Air Quality Control in Public Use Facilities, Etc. Act, School Health Act, Public Health Control Act and Parking Lot Act in Korea. It was surveyed that a total of 32 countries including 24 countries in the European Union(EU), six countries in Asian and two countries in North America setting the reference levels for radon in the world. Results: In Korea, there are set guidelines for radon in the Ministry of Environment and the Ministry of Education. Reference levels of radon for existing dwellings were $150{\sim}400Bq/m^3$ for Western European countries, and $200{\sim}1,500Bq/m^3$ in Eastern European countries. Approximately 67% of those EU countries were set up $400Bq/m^3$ to the standards for existing dwellings. EU countries such as Luxembourg, Finland, Norway, Sweden and Russia had adopted mandatory level for radon. Radon guidelines for new dwellings were set more strictly reference level($200Bq/m^3$) than existing dwellings. Conclusions: International organizations such as ICRP, UNSCEAR and NCRP, etc. had recommended the guidelines for radon. It was calculated the relation of the dose conversion factors with the annual effective doses. the OELs of radon suggest to need to establish $150Bq/m^3$ for office room and $400{\sim}1,000Bq/m^3$ for the workplace.

Recently, mandatory BIM design has been enforced in the civil engineering field, focusing on public projects, and inducement measures to actively participate in BIM by participating subjects are required. The BIM ordering documents must reflect the characteristics of the BIM project, current construction standards and laws, and environmental conditions of domestic participants. In this study, we analyze the ordering documents used in domestic and overseas civil engineering BIM projects to determine whether they meet the purpose of BIM. In the future, items that consider the existing heterogeneous data linkage and compatibility, the connectivity with the current construction guidelines and laws, the cost of the designer and the input personnel are prepared for the part that does not meet the BIM purpose. Furthermore, the written order documents are verified through interviews with experts who have experience in BIM projects. Through the results of this study, I would like to propose a consultation system strategy to prepare and present items according to the purpose and type of project by client.

In South Korea, there is a growing domestic need for a biotope map which contains ecological and environmental geographic information of a city. After the production of a Urban Ecological Maps(biotope map) by the Seoul metropolitan government in 2000, Natural Environment Conservation Act was revised in 2017 to make it mandatory for a local government to draw up its own urban ecological map. The aim of the present study was to find out ways to utilize an urban ecological map as a mean of communication between natural environment planning and urban planning sectors in a preliminary stage before introducing a big framework of 'environmental and ecological planning.' The northern area of Incheon metropolitan city was selected as the target area for this study. The major research content includes a comparative analysis of special-purpose zones, urban planning zones, restricted development zones, and conservation forests with focus on biotope types and Grades 1 of 'Biotope Type Assessment.' Farmland biotopes and forest biotopes within an area designated as an urban zone (residential, commercial and industrial zones) need to be redesignated as a zone which can conserve them. Especially considering a high possibility of damage to a large scale of natural green areas, these areas need to be readjusted immediately. If the entire area designated as an urban planning zone is to be developed, it is likely to cause serious damage to natural biotopes in the area (56.2%), including farmland biotope (30.4%), forest biotope (15.0%) and grassland biotope (10.8%), and thus, readjustment is needed. In case of a conservation forest, as it can possibly be damaged by the designation of special-purpose zones, it is necessary to match the designation of conservation forests or a special-purpose zones with their biotope types. In conclusion, we present a variety of thematic maps for utilization of an urban ecological map and propose a phase-specific environmental and ecological plan. Phase 1 is the establishment of a urban plan in consideration of ecological status; Phase 2 is the independent establishment of an environmental and ecological plan by an environment department; Phase 3 is an integrated management of ecological planning system and urban planning system.

In urban space, public space is publicly or privately owned space freely accessible by the public. Privately owned public space to the public hosts small-scale rest facilities to serve the public in buildings of certain purposes and sizes for the sake of pleasant urban environment. The Building Act and building ordinances formulate a set of criteria for management and easement of construction standards as well as the area. When creating privately owned public space, one can get incentives through the easement of floor space index and height limit. The purposes of this study were to investigate and analyze privately owned public open space, which is freely accessible by the public, and its adjacent streets and to propose plans to improve the regulations for securing privately owned public space for more rational and practical legal applications. The study then proposed some plans to help to increase the quality of privately owned public space including applying the coefficient to suggest the type of privately owned public space fit for the features of the streets and measure the appropriate utility level differently and distinguishing the mandatory items according to the facility regulations in privately owned public space from the ones qualified for additional points in case of installation. The types of privately owned public open space should be applied differently and the content of facilities intended should be different according to whether it will serve as a resting place or grant more importance on traffic by walking, depending on the features of its adjacent streets. The privately owned public space, the frontage space of building, and the adjacent sidewalks should become a whole and be regarded as one space from the integrated perspective. The results of the study claim further significance in that it investigated privately owned open space and roadside across Seoul. They will serve as useful data to solve the problems with the privately owned public space of the city, which destroys spatial continuity by focusing on the quantitative increase of privately owned open space and creating individual privately owned open spaces and builds high-rise buildings alienated from the existing spaces, and to increase the quality of future privately owned public space.

This study presents the results from a technical analysis of a portal system that is compatible with MRV regulations and utilized to examine energy efficiency in international shipping, in relation to the implementation of a mandatory data collection system by the International Maritime Organization. The details of the SEEMP guidelines, including the data collection system and methods for collecting data on fuel use, were reviewed. Strategies for domestic shipping companies toward MRV have been recommended by identifying differences with the EU MRV, and the technical adequacy of the MRV system was assessed. The MRV system enhances cost and work efficiency by managing emissions data from the early stage to the final stage. It is capable of collecting and reporting emissions data while adhering to the reporting procedures of shipping companies. By granting different access privileges to users, the system supports shipping companies in their data collection and reporting, and also supports verifiers in their data verification activities. Moreover, it makes possible the submission of reports in electronic from, thereby enabling shipping companies to adopt an integrated response to international MRV regulations.

Since the age of Lord Mansfield, who laid the foundation of the modern English insurance contract law in the second part of the 18th century, English insurance law has developed a unique rule of warranty. Lord Mansfield adopted very different approach and afforded such a strict legal character to insurance warranty, because the promise, given by the insured, played an important role for the insurer to assess the scope of the risk insured at that time. It is still important that the insured keep his promises strictly to the insurer under the insurance contract, but legal environments have changed dramatically since the times of Lord Mansfield. English Law Commission proposed some proposals for reforming the warranty regime to reflect the changes of legal environment in CP 2007. This article is, therefore, designed to examine the proposals and consider their legal and practical implications. The proposals of Law Commission is summarized as following. First, in CP 2007, Law Commission made two principal proposals for reform of the law on warranty. The first is that the insurer should not be entitled to rely on a breach of warranty unless the insured has been provided with a witten statement of what they have undertaken under warranty. The second is that the insurer should not be entitled to reject a claim on the ground that the insured has breached a warranty unless there was a causal connection between the breach and the loss. Secondly, for consumer insurance, the rule requiring a causal connection would be mandatory, whereas for business insurance, it would be possible for the parties to agree on the effect a breach of warranty should have, provided they use clear language to express their intentions. Thirdly, where the insured contracted on the insurer's written standard terms of business, some statutory controls would be afforded to the contract to ensure that the cover was not substantially different from what the insured reasonably expected. Finally, Law Commission propose that a breach of warranty give the insurer the right to terminate the contract, rather than automatically discharging it from liability, but (unless otherwise agreed) only if the breach has sufficiently serious consequences to justify termination under the general law of contract. Having evaluated the proposals of the Law Commission and considered their legal and practical implications, it is quite clear that the proposed rule interfere with freedom of contract and create legal uncertainty. But change can not made without any victims, so Law Commission's attempt to change severe and injust aspects of the warranty regime would be very welcomed and respected.
