The materials applied to the aircraft fuselage, parts, and components must be verified by relative authorities in accordance with the procedures set by the airworthiness authority to achieve the aircraft type certification. There are no examples of domestic composite materials which were verified in order to be applied to aircraft structure. In this study, the composite material certification system of NCAMP, an American composite material standard certification organization, was reviewed and used as the fundamentals of the first aerospace composite material certification system in ROK(Fig 2,8). Also updated material certification documents were developed and confirmed by material certification engineers and inspectors. This aerospace composite material qualification system is intended to modernize the material certification system for AAM(Advanced Air Mobility) as well as aircraft and to enhance the understanding of related technicians and inspectors.

공공부분 S/W사업은 분리발주가 원칙이고 일괄발주가 예외지만 현재 많은 공공부분 S/W사업은 일괄 발주 사업으로 진행되고 있다. 일괄발주는 SI업체가 S/W업체도 선택하여 입찰 및 개발하기 때문에 발주자가 원하는 품질 좋은 S/W를 선택할 수 없고, 발주자가 S/W를 업그레이드 및 확장할 때 SI업체에 의존하게 되는 단점이 있다. 이런 단점을 보완하고, S/W분리발주를 활성화시키기 위해 지식경제부(구 정보통신부)에서는 S/W분리발주 매뉴얼을 작성하여 보급 및 교육을 하고 있으며, 발주처에서는 품질이 우수한 S/W를 선택하기 위한 S/W분리발주 BMT를 공인된 시험기관인 한국정보통신기술협회(TTA) SW 시험인증센터에서 BMT를 실시하고 있다. 본 논문은 위협관리시스템(TMS) S/W분리발주 BMT를 공인된 국가 시험인증기관인 한국정보통신기술협회(TTA) SW시험인증센터에서 수행한 사례를 기술하였다

Smart phone zombie or Smombie means pedestrians who walk without attention to their surroundings because they are focused upon their smart phone. Because the traffic accidents and injuries caused by Smombie have been increased rapidly in recent years, the social attention and policies are needed to prevent it. This study was conducted to analyze Smombie's current status and some solutions used before and to propose new improved method through the latest ICT trend. In this study, we did the field survey to check Smombies at several places in Seoul through people counting, and found that a lot of pedestrians still use the smart phone while walking. And we analyzed many case studies about some solutions to prevent Smombies previously. The case studies include legal regulations, government policies, smart phone app services and facilities that are used before. We studied them through internet searches and reference studies and we also checked the current operating situation as visiting several places that the solutions actually has been operated. Therefore, we found there are some limitations in previous solutions in terms of effectiveness and management. To consider new solution that can be expected to overcome the limitations, we analyzed the latest ICT trends focused on features to utilize the Smombie prevention, especially video recognition and digital signage. In these days, video recognition has been developed rapidly with assistance of AI technology and it can recognize the specific pedestrian's characteristics such as holding smart phone as well as hair style, clothes, backpack and etc. On the other hands, the digital signage is the convergence device that includes big display, network connection and various IoT sensors. It can be used as public media in many places for public services as well as advertising. Through these analysis results, we show the requirements and the user scenario for the improved method to prevent Smombie. Finally, we propose to develop R&D technology to recognize Smombie exactly as pedestrian attributes and to spread creative contents to increase pedestrian's interest and engagement for Smombie prevention through digital signage.

Researches and developments of tidal energy converters are close to commercialization stage. But, commercialization of tidal energy converters is not ready in korea. In Europe, many experts of company, laboratory and public institution involved in marine energy are active for commercialization of marine energy converters in European Marine Energy Centre. Furthermore, in IEC/TC114, standardization of technical standards for assessment and certification of tidal energy converters of each country is under discussion. Therefore, We have to prepare for commercialization, standardization and entry into the overseas market. In this study, trends of commercialization and standardization of international markets of marine energy converters are investigated and certification schemes of overseas are analyzed. We expect that this study will make contribution to establish the foundation of commercialization of tidal energy converters.

The names of medical technologist in Korea, Japan, and the United State of America vary depending on the medical system, educational system, and work areas. Conventionally, jobs equal or similar to medical technologist (commonly known as clinical laboratory technologist, medical laboratory technologist, clinical laboratory scientist, and medical laboratory scientist), histotechnologist, cytotechnologist, and genetic technologist. Jobs, such as extracorporeal technologist, medical electrophysiology technologist, and medical sonographer, allow other allied health professionals including medical technologists, to obtain their qualification. The work areas of medical technologists are classified into clinical pathologic technology, pathologic technology, clinical genetics technology, nuclear medicine in vitro technology, and clinical physiologic technology. New titles of Korean specialized medical technologists refer to certification systems, such as CLMJ, CMAJ, ASCP, IAC, ABRET, and ARMDS. Currently, there are eight types of specialized medical technologists under the cooperation of specialized academic societies. They are hematology, transfusionology, chemistry, immunology, microbiology, histology, cytology, nuclear medicine. It can be further divided into 20 categories according to the work areas such as mass spectrometry, infection control, Pathologists' Assistant, flow cytometry, HLA, cytogenetics, molecular genetics, cardiopulmonary physiology, neurophysiology (EEG/EMG/PSG/etc.), cardiac sonography, neurosonography (TCD/carotid), and medical device quality manager.

Meteorological data is one of the important factors in the calculation of building energy demand. The purposes of this study are to review the limitations of the typical meteorological data of ECO2 program and to create the new typical meteorological data and then analyze the building energy demands for additional regions which are not included in the existing 13 region in the ECO2 program. The extended typical meteorological data to a total of 33 regions were based on IWEC(International Weather for Energy Calculations) data files and were created in the form applicable to the building energy efficiency rating certification system. As a result of comparing the heating energy demands of a representative region with the surrounding regions in each of five regions in Korea, the variance of Cv(RMSE) ranged from 36% to 344% and MBE ranged from -32% to 190% for the whole regions. This suggests that the difference of heating energy demand may vary greatly depending on the region where the meteorological data is used and the meteorological data of more detailed regions is needed for reliable calculation of building energy demand.

Purpose: Reducing energy consumption and greenhouse gas emissions is a primary concern throughout the world, and the building sector is a particularly efficient area for making these reductions. In South Korea, the government has recently enacted policies for "Green Growth" that, among other things, enforce regulations in the building certification rating system (BCRS) and reorganize existing incentive systems. Method: In this study, we examined regulations and incentive systems used in the United Kingdom, Germany, and the United States that encourage the use of energy efficient technologies in construction and compared these policies to those used in South Korea. We also disseminated surveys to experts in the fields of architecture, planning and design, and engineering to better understand their knowledge and perception of the BCRS and its incentive systems. Additionally, we sought their recommendations for improving these incentive systems. Result: Based on our comparative case studies of regulations and incentives in other countries, alongside recommendations from experts in South Korea, we concluded that incentive systems in South Korea are limited and require improvement. We make recommendations for strengthening existing regulations and incentives and for implementing new incentive programs.

Scanners play an important role in digitally reproducing the color and imaging of original documents used in public offices; however, the current system lacks a standard for digitized documents created by scanners, complicating efforts to create a digitized system. In particular, macrography cannot guarantee the accuracy and reliability of digitalized color documents, pictures, and photographs created by scanners. To this end, we develop a standardized evaluation tool and test target to certify digitalized documents created by a scanner in the domestic environment. In this study, we enhance the accuracy and reliability of scanned data to create an advanced standard evaluation tool for scanners. Moreover, to produce a scanner certification standard, we overcome existing problems related to the growing market. We anticipate that this new standard will see a high degree of application in the current environment.
