For the purpose of establishment of Reference Korean and estimation of internal and external exposure doses in the Reference Korean, we have surveyed reference values for Koreans, such as physical standards including height, weight and body surface area, food consumption rate of daily intake of radioactive substances and exposure dose from natural radiation. The results obtained are as follows: 1) The age group of the Reference Korean ranged from 20 to 30 years old in both sexes. The height, weight and surface area of the body of the Reference Korean are 167cm, 61kg and $1.67m^2$ in male and 155cm, 51kg and $1.51m^2$, respectively in female. 2) The food consumption of the Korean is 812.8g (669.6g of vegetable food and 143.2g of animal food) per capita per day. 3) Koreans are taken about 1,200 pCi of radioactive substances(${\beta}$-ray) per capita per day. 4) The external and internal radiation exposure doses of the Korean are estimated to be 127 mrem and 8 mrem per year, respectively. However, it is believed that these values will be modified upon the addition of data collection.

Accidents due to aircraft fuel defects rank in the top 13 of the 34 accident types described by CAST-ICAO Common Taxonomy Team(CICTT). Aircraft accidents occur because of the inflow of moisture or pollutants depending on the distribution process and storage environment. To confirm the change in physical properties of the aircraft oil stored for a long time, we stored JET A-1 aircraft oil in a metal can to observe the change after six months. We confirmed that the aircraft oil stored for a long time satisfied the quality standards, and the stability of the fuel oil was high. However, in scenarios in which aircraft oil is stored separately on ships, onshore storage facilities, oil fields, etc., owing to the nature of missions, such as in marine police aircraft, the inflow of moisture or pollutants may likely occur due to changes in the internal and external environment. In addition, pollutants can be analyzed using existing tests and distillation properties, but for moisture, domestic and international standards and domestic laws determine the moisture separation ability of aircraft oil through the water separation index, but the moisture content is not analyzed. Therefore, aviation safety must be secured by adding quality control standards for moisture content and performing revisions to uniformize domestic and international standards and laws.

The recognition of the environment and its importance have generated various types of parks, such as the ecological put the environmental put and the natural academy. They are considered the connecting media for the creation of space as a new paradigm in design for the 21st century from the late 1990s, environmental designs in space planning have been created from various angles of Perspectives including restoration of the natural ecosystem and introduction of natural circulation systems. Based on the aye facts and through theoretical examination of environmental park models, this research (1) establishes the concept and the significance of environmental parte; and, based on this, classifies the types of industrial sublimity; (2) presents environmental designing principles and standards; and (3) presents the "Chung Ra pro-Environmental Park plan" based on these ideas. The following is the summary of research results: First, while existing city parks are human-oriented, interior-oriented, and shape-centered, an environmental park considers human and nature equally and gives great importance to the relationship between the internal and external of the subject. It is a mark of environmental education that considers the natural ecosystem. Therefore, the environmental park is the 21st Century′s type of an open park for creating new forms of nature, as well as for incorporating culture and values through education. In such an environmental system, nature, culture, and human beings pursue balance, harmony, and security through mutual recognition. Second, in a broad sense, the types of environmental park can be classified into Cultural Restoration, Ecological Conservation, and Environmental Replacement. Third, by selecting Chung na environmental park in Incheon, which is a filtration plant lot, as a research subject, I have presented alternative planning for environmental parte in which culture and nature coexist on the basis of environmental planning principles and standards.

The Giant Magellan Telescope (GMT) will feature two interchangeable Gregorian secondary mirrors, an adaptive secondary mirror (ASM) and a fast-steering secondary mirror (FSM). The FSM has an effective diameter of 3.2 m and built as seven 1.1 m diameter circular segments, which are conjugated 1:1 to the seven 8.4m segments of the primary. Each FSM segment contains a tip-tilt capability for fine co-alignment of the telescope subapertures and fast guiding to attenuate telescope wind shake and mount control jitter. This tip-tilt capability thus enhances performance of the telescope in the seeing limited observation mode. As the first stage of the FSM development, KASI conducted a Phase 0 study to develop a program plan detailing the design and manufacturing process for the seven FSM segments. The GMTO-KASI team matured this plan via an internal review in May 2016 and the revised plan was further assessed by an external review in June 2016. In this poster, we present the technical aspects of the FSM development plan.

Objectives: By analysing the recent trends of published papers in the Korean Journal of Health Education and Promotion, this study aims to identify and discuss some challenging issues, and to provide recommendations for quality improvement of the research papers. Methods: One hundred and sixty five papers published between 2009 and 2011 were examined and categorized according to selected standards. Results are displayed in frequencies and percentages. Results: The volume of articles published has increased by two-folds in three decades since the publication of the first issue. More than 90% of the papers were original articles. Cross-sectional research design was most frequently applied, while only 11.5 % of the articles were intervention studies. For cross-sectional research articles, limitation in generalizability of the study findings was mentioned as one of the major issues, in relation with the frequent use of convenient sampling methods and lack of theoretical evidence in inclusion of variables. Consideration of internal and external validity of the study, utilization of scientific evaluation design and mixed evaluation methods were recommended for intervention research to improve the quality of the research results. Conclusion: To serve as a key resource for evidence-based practices in health promotion, more strict scientific research criteria should be applied to the articles published in the Korean Journal of Health Education and Promotion.

Because of the development of the 4th industrial technology such as artificial intelligence and the corona situation, the recent university society is rapidly changing. As the college entrance exam environment is also getting seriously difficult, departments and majors are rapidly changing at the university. Therefore, the department of the university needs a curriculum for new majors or convergence majors according to the internal and external environment of the department. However, it is a very difficult and time-consuming task to develop such a curriculum accurately. This paper proposes a curriculum development method and an application case using the National Competency Standards(NCS). The curriculum development method proposed in this paper consists of the traditional three-step method, namely, analysis, design, and development, and NCS is used in each step. This proposed method focused on reducing the time of curriculum development, and an example of curriculum development is presented for the usefulness of the proposed method.

Background: It is very difficult to set a regulatory guidance or criteria for the protection of non-human species from the ionizing radiation, because there are no generally or internationally accepted methods for demonstrating the compliance with such criteria. It is needed that Korea develop the primary dose rate standards for the protection of both aquatic and terrestrial biota in the near future. Materials and Methods: The potential dose rates due to both external and internal radiation exposures to marine organisms such as plaice/flounder, gray mullet, and brown seaweed collected within territorial seas around the Korean Peninsula were estimated. Results and Discussion: The total dose rates to plaice/flounder, gray mullet and brown seaweed due to $^{40}K$, a primordial radionuclide in marine environment, were found to be 0.2%, 0.08% and 0.3% of approximately the values of the Derived Consideration Reference Levels (DCRLs, i.e. $1-10mGy{\cdot}d^{-1}$), respectively, as suggested by the International Commission on Radiological Protection (ICRP) publication 124. The total dose rates to marine fishes and brown seaweed due to anthropogenic radionuclides such as $^{90}Sr$, $^{137}Cs$ and $^{239+240}Pu$ were considered to be negligible compared to the total dose rate due to $^{40}K$. The external exposure to benthic fish due to all radionuclides was much higher than that of pelagic fish. Conclusion: From this study, it is recommended that the further study is required to develop a national regulatory guidance for the evaluation of doses to non-human species.

IMO is treating various and numerous agenda with time, and the contents of agenda have been tending to achieve international standardization for details of technology, for example GBS(Goal based new ship construction standards), PSPC(Performance Standards of Protective Coating), LRIT(Long-Range Identification and Tracking of Ships), etc. This paper presents the latest agenda trend of IMO committees and analyzes the ROK's activities in response to IMO committees. In the result of analysis, ROK lacks in performance ability as a A-category council member as well as infrastructure to support the government activities in IMO continuously. Therefore, ROK should be conscious of policy approaches to international maritime tendency and needs to complete the internal/external infrastructure which leads the international maritime policy.

The present study was to develop a dry PFB method similar to the existing gypsum board construction method in order to apply the existing wet PFB method that uses fire-resistant adhesive. It was found that the existing wet method can produce concrete compressive strength of 80MPa and fire resistance of 3 hours with 30mm PF boards. The goal of development in this study was fire resistance of 3 hours through dry construction of 15mm fire-resistant boards. 1. Improved PF board was prepared by adding inorganic fiber to existing board and using aggregate with grain size of 3mm or less. Molding was done at temperature higher than that for existing PF board molding. While wet curing is used for existing PF boards, this study used dry curing in order to enhance heat insulation performance. 2. According to the results of fire resistance test, when the dry PF method was applied, the temperature of the main reinforcing bar was 116℃ in 15mm, 103.8℃ in 20mm, and 94℃ in 25mm, and these results satisfied the current standards for fire resistance control presented by the Ministry of Land, Transport and Maritime Affairs. When a 3-hour fire resistance test was performed and the external properties of the specimen were examined, the outermost gypsum board hardly remained and internal PF board maintained its form without thermal strain.
