  • This technical report was developed to suggest the guideline to assess the safe use and handling metalworking fluids (MWFs) in machining operation. The basis of this method developed in this study was based on self assessment procedure recommended by Organization Resources Counselors (ORC) of the United States (US). In addition, various MWF management elements obtained from the review on various articles, reports and author's experience regarding MWF were newly added to the evaluation guideline. A total of four areas were finally selected in order to control exposure to MWF used in machining operations. They are all related to the presence and efficiency of the control measures, exposure assessment, management on tank and sump, and safe treatment of chips and metal fines generated during machining operations. Each area is consisted of several related elements. Several evaluation areas and elements used in this study could be revised, replaced, added and deleted according to the process environment, evaluation objectives and evaluator's (manager) criteria etc. This evaluation guide manual could be used for safe management of MWF in metalworking operation. In addition, industrial hygienists can use this evaluation method for auditing and evaluating the management status on MWF.

  • In both Korea and the U.S., science education leaders and specialists insist that there is a shortage of curricula to address the new national science education guidelines in support of reform. This paper addresses development of new curricula for science education reform in the hopes of facilitating further development of guideline-based curricula. We examine Korean and U.S. thematic-based (Korean Science Field Trip at Cultural Sites Program and U.S. Graduate Teaching Fellows in K-12 Education) and project-centered (Korean Teachers for Exciting Science and U.S. Foundational Approaches in Science Teaching Program) programs. Using the criteria of rationale for curriculum, content and scope, processes of implementation, and assessment strategies, we identify the curricular components that are common across four successful secondary science programs and determine which of these components address the national guidelines. Our findings indicate that common components of these four programs meet the expectations of the science guidelines being used to revamp science education in both countries. Therefore, these programs not only engage secondary students and teachers in practicing successful science education, but also lead to successful science education practices that can be incorporated in the future development of curriculum to support secondary science reform.

  • Cardiac organoids have emerged as invaluable tools for assessing the impact of diverse substances on heart function. This report introduces guidelines for general requirements for manufacturing cardiac organoids and conducting cardiac organoid-based assays, encompassing protocols, analytical methodologies, and ethical considerations. In the quest to employ recently developed three-dimensional cardiac organoid models as substitutes for animal testing, it becomes imperative to establish robust criteria for evaluating organoid quality and conducting toxicity assessments. This guideline addresses this need, catering to regulatory requirements, and describes common standards for organoid quality and toxicity assessment methodologies, commensurate with current technological capabilities. While acknowledging the dynamic nature of technological progress and the potential for future comparative studies, this guideline serves as a foundational framework. It offers a comprehensive approach to standardized cardiac organoid testing, ensuring scientific rigor, reproducibility, and ethical integrity in investigations of cardiotoxicity, particularly through the utilization of human pluripotent stem cell-derived cardiac organoids.

  • Purpose: Environment test aim to validate the guarantee of required capability of materiel against various environment conditions which exposed during materiel life-cycle. In this paper, environment test design procedure and tailoring guideline for Korean peninsula and periphery climate are proposed. Methods: To design tailoring guideline, climate data which are regarding Korean peninsula and periphery regions provided from Korea Meteorological Administration (KMA) and National Climatic Data Center (NCDC) are used. Conclusion: For effective environment test, it is important that environment test have to design in considering environment conditions during materiel life-cycle. It is concluded that the high temperature test level can be softer than the test criteria in MIL-HDBK-310, however, the low temperature test level will be expected to be $2{\sim}6^{\circ}C$ harsher than MIL-HDBK-310.

  • The purpose of the study is to analyze the existing situation of the green buffer zone in the large scale industrial site and other major residential apartment areas. In this study, it is specifically intended that the planning guideline be upgraded to adopt future landuse trends and thus to suggest design criteria for management of the buffer zone. The framework of the analysis is to review the current landuse, noise reduction, ecological implications and landscape in general. Although the major function of a green buffer zone is considered to protect the residential area from various hazards of industrial, traffic, and visual environment, the situation is that most of the zones are maintained at a minimum level of services by local government. The study carried out intensively almost every type of case studied throughout the country, which implies that the management of the green buffer zone should be expanded physically enough to function for its original objectives. The study recommends that ecological management of the green buffer zone be emphasized and therefore the criteria for this purpose as well as noise issue should be developed prior to the landuse aspects. The study suggests specific guidelines for planning and design for the green buffer zone development. This study should be verified positively through the sustainable monitoring and requires nationwide and overall examination so that it may be applied to whole green spaces.

  • Purpose: Recently, Universal design has been applied to a variety of concepts of social integration in the national legislation and institutions, however, the applying to urban railway station is not satisfied. Most of cases, the handicapped can not work continuously, universal design must be provided. Methods: This study derives the detailed criteria through comparing and analyzing an national and international universal design-related system in transit zone. And the status is investigated in transit zone of domestic urban railway station. Improved national standard requirements are derived considering the type of the handicapped and universal design principles. Result: The domestic status shows that the most lacking entry criteria is not specified in national standards or the design is a lowest-level required by criteria through comparing detailed criteria drawn into domestic analysis. Therefore, in order to provide a pedestrian environment to meet the universal design principles and requirements for the handicapped, there is a need to re-establish with a specific national standards. Implications: This study will draw on universal design standards for seamless transfer in transit zone of urban railway station. The next studies are needed to target the overall paths ranging from outside to landing in urban railway station.
