Purpose: This paper aims to explore approaches for obtaining KOLAS certification for masks developed as protective equipment for use during evacuation processes in the event of a radiation disaster involving residents within a radiation emergency planning zone. Method: Various reports, papers, and data from the KOLAS accreditation bodies' websites were examined for this study. Result: Although domestic radiation disaster preparedness measures have been established to enhance resident protection, the distribution of protective equipment is limited to thyroid protection drugs. Supplementary support items like masks are necessary to prepare for radiation disasters. Currently, there is no KOLAS-accredited certification body for radiation protection masks. Conclusion: For masks that have established performance certification criteria, a dual process is required for KOLAS certification. This involves obtaining an official test report as an industrial respirator mask, receiving certification, and then obtaining a general test report based on internal standards.

Since the cyber defense has been dependent on commercial products and protection systems, in aspect of the recent trends, our cyber defence ecosystem can be more vulnerable. In case of general defense weapon companies, they have to be observed by the government such as certain proprietary technologies and products for the protection from the enemy. On the contrary, most cyber weapon companies have not been managed like that. For this reason, cyber attack can reach to the inside of our military through the security hole of commercial products. In this paper, we enhanced a military cyber protection ecosystems out of enemy attacks and analyze the hypothetical scenarios to evaluate and verify the vulnerability, and finally more securable ecosystem of military protection system is presented politically and technically.

원자력발전소 화재방호기준인 KEPIC 원자력발전소 화재방호기준과 대부분의 소방시설관련 NFPA 기준에서는 소방시설 또는 소방시설에 사용하는 구성품(이하 "소방용품"이라 한다)은 관할기관(AHJ : Authority Having Jurisdiction) 받아들일 수 있는 인증(Approved) 되거나 등록된(Listed)된 제품을 사용하도록 규정되어 있다. 따라서 KEPIC 기준이 국내 원자력 발전소에 적용되기 위한 선결과제로 KEPIC 기준에서 요구하는 소방용품의 수급이 원활이 이루어질 수 있는지의 검토가 필요하다. KEPIC 기준은 대부분 NFPA 기준을 적용하고 있기 때문에 KEPIC 기준대로 설계가 이루어지려면 NFPA 기준에서 요구하는 동등이상의 구조와 성능을 갖는 소방용품으로 소방시설을 설치할 필요가 있다. 미국의 경우 일반적으로 UL인증제품이나 FM인증제품이 NFPA 기준에서 의미하는 관할기관이 요구하는 인증 및 등록된 제품으로 인정되고 있으나, 국내의 경우 소방관계법규에 근거하여 정부규격(소방방재청 고시)에 의해 주요 소방용품에 대한 의무검정제도를 운영하고 있어 원자력발전소 화재방호에 KEPIC 기준을 적용할 경우 소방용품의 수급이 원활치 않을 수 있으므로 국내에서 검정받은 소방용품으로 대체할 수 있는 지의 검토가 필요하다. 이에 따라, 국내 소방검정제도와 미국 UL인증제도를 비교하고 또한 국내 기술기준과 UL인증 시험기준이 있는 대표적 주요 소방용품 10가지에 대한 국내검정기준과 미국 UL인증 시험기준의 비교분석 등을 통하여 원자력발전소 화재방호에 KEPIC기준이 적용될 경우에 합리적인 소방용품의 적용방안에 대하여 검토하였다.

Energy absorption facilities installed on roads should follow the performance standards of the real-car crash test of 'Installation and Maintenance Guidelines for Roadside Safety Facilities'. However, due to different installation conditions, such as differing structure widths on roads, some energy absorption facilities do not provide adequate performance. In order to apply varied environments on roads, an energy absorption structure was designed in this study with 150 mm height and four layers of W-shape guardrail at 200 mm intervals, and the performance was verified using LS-DYNA computer simulation. Through a real-car crash test, the performance of the facility designed by LS-DYNA was tested and was found to meet the performance of the CC2 category for crash cushions. The conclusion of the comparison demonstrates that the simulation and the real-car crash tests are both significant.

This study is an analysis of characteristics and the causes of serious accidents in chemical industry. The statistical analysis was focused on preventive facilities, equipment failures, accident materials and instabilities of workers and employment type. First, it showed that the highest number of the victims of accidents were involved in the industry of chemical materials and chemical products among the investigation of the manufactural industries. Also, particularly, they were investigated to be focused on the occurrence of the serious accidents in preventive facilities. Secondly, the most of the victims of serious accidents were found out not to be temporary or part-time worker but regular workers and most of the accidents occur in the form of big accidents involving more than 4 workers.

The HEMP threat may have acquired new, and urgent, relevance as the proliferation of nuclear weapons and missile technology accelerates of the North Korea, for example, is assessed as already having developed few atomic weapons, and is on the verge of North Korea already has missiles capable of delivering a nuclear warhead against South Korea. ITU K.78, K81 and IEC recommended its counter-measuring for the industrial facilities with navigation and sailing facilities in order to obviate the all of processor equipped system malfunctions from the EMP/HEMP but its simulation must only be done by the computer simulation which had studied on the 1960-1990 years USA/AFWL papers. This result has a significant activities to the South Korea being under the North Korea threat because all of HEMP related products was strongly limited for export. The HEMP cord which was developed newly by the KTI including the HEMP generation & propagation analysis, optimal shelter design tool, essential EM energy attenuation in multi-layered various soils and rocks and HEMP filter design tool. Especially, the least square fitting method was adopted to analysis for the EM energy attenuation in the soils and rocks because it has a various characteristics based on the many times field test reports.

The allyl isothiocyanate, capsaicin and dihydrocapsaicin as main components in self defense sprays were determined by gas chromatography-mass spectrometer (GC-MS). Although self defense spray was used to protect by myself, a social problem could be caused by the hazard of spray chemical due to use pungent liquid. To identify this, the pH of pungent liquid solutions, solubility to detergents, the existence of other materials and the types and amounts of pungent material in spray chemicals were investigated in this work. Finally, the amounts of allyl isothiocyanate, capsaicin and dihydrocapsaicin as pungent materials in them were determined by GC-MS. The pH of chemicals were about 5.7 as weak acid, the detergents can emulsify them with water well. And they did not contain fluorescent materials and hazard organic solvents. The pungent components in three real samples were only allyl isothiocyanate [47,600 mg/kg (47.6%)] in one sample, and mixtures with capsaicin [228 mg/kg~368 mg/kg (1.14%~1.84%)] and dihydrocapsaicin [224 mg/kg~414 mg/kg (1.12%~2.07%)] in the others, respectively.

This paper mainly describes the armor materials, especially the ceramic materials for the personal protection. In the ceramic armor materials, B4C ceramics and SiC ceramics are the most popular materials. The $B_4C$ ceramics which consists of 4 atoms of boron and I atom of carbon is very light and strong. It is usually used to personal protection armor and chair protection in the helicopter. This material must be sintered at very high temperature because it melts at $2400^{\circ}C$. In order to have a good armor property, it must have very high density which is achieved by hot press or subsidiary sintering aid methods such as reducing the particle size of raw materials or mixing the sintering agents to the raw materials.
