Orthorhombic dysprosium manganite DyMnO3 with single phase is synthesized using solid-state reaction technique and the crystal structure and dielectric properties as functions of temperature and frequency are investigated. Thermally activated dielectric relaxations are shown in the temperature dependence of the complex permittivity, and the respective peaks are found to be shifted to higher temperatures as the measuring frequency increases. In Arrhenius plots, activation energies of 0.32 and 0.24 eV for the high- and low-temperature relaxations are observed, respectively. Analysis of the relationship between the real and imaginary parts of the permittivity and the frequencies allows us to explain the dielectric behavior of DyMnO3 ceramics by the universal dielectric response model. A separation of the intrinsic grain and grain boundary properties is achieved using an equivalent circuit model. The dielectric responses of this circuit are discerned by impedance spectroscopy study. The determined grain and grain boundary effects in the orthorhombic DyMnO3 ceramics are responsible for the observed high- and low-temperature relaxations in the dielectric properties.

Environmental pollution remains a considerable health risk source all over the world; however, hazards are usually higher in developing countries. Iraq has long been suffering from the problem of pollution and how to treat pollution. Photocatalytic degradation has turned out to be most productive process for dye degradation. In this investigation, Rhodamine B (RhB), dye has been selected for degradation under visible light illumination. To address this issue, we fabricate erbium trioxide nanoparticles (Er2O3/NPs). Erbium trioxide nanoparticles are prepared and utilized for photo-catalytic degradation. The characterization of Er2O3/NPs is described and confirmed by utilizing of XRD (X-ray diffraction) and SEM (Scanning Electron Microscopy). The average size of Er2O3 nanoparticles is observed to be 16.00 nm. Er2O3/NPs is investigated for its ability of photo-catalytic degradation through certain selected parameters such as concentration and time. The methodological results show that the synthesized Er2O3/NPs is a good photo-catalytic for Rhodamine degradation.

New triple tungstate phosphors NaPbLa(WO4)3:Yb3+/Ho3+ (x = Yb3+/Ho3+ = 7, 8, 9, 10) are successfully fabricated by microwave assisted sol-gel synthesis and their structural and frequency upconversion (UC) characteristics are investigated. The compounds crystallized in the tetragonal space group I41/a and the NaPbLa(WO4)3 host have unit cell parameters a = 5.3927(1) and c = 11.7961(3) Å, V = 343.05(2) Å3, Z = 4. Under excitation at 980 nm, the phosphors have yellowish green emissions, which are derived from the intense 5S2/ 5F4 → 5I8 transitions of Ho3+ ions in the green spectral range and strong 5F5 → 5I8 transitions in the red spectral range. The optimal Yb3+:Ho3+ ratio is revealed to be x = 9, which is attributed to the quenching effect of Ho3+ ions, as indicated by the composition dependence. The UC characteristics are evaluated in detail under consideration of the pump power dependence and Commission Internationale de L'Eclairage chromaticity. The spectroscopic features of Raman spectra are discussed in terms of the superposition of Ho3+ luminescence and vibrational lines. The possibility of controlling the spectral distribution of UC luminescence by the chemical content of tungstate hosts is demonstrated.

The purpose of this study is to fabricate an ophthalmic lens by copolymerizing two types of carbon nanotubes and hydrophilic hydrogel lens materials, and to investigate its application as an ophthalmic lens material by analyzing its physical properties and antimicrobial effect. For polymerization, HEMA (2-hydroxyethyl methacrylate), EGDMA (ethylene glycol dimethacrylate), a crosslinking agent, and AIBN (azobisisobutyronitrile), an initiator, are used as a basic combination, and a single-walled carbon nanotube and a single-walled, carboxylic-acid-functionalized carbon nanotube are used as additives. To analyze the physical properties, the water content, refractive index, breaking strength, and antimicrobial effect of the fabricated lenses are measured. The fabricated lenses satisfies all the basic properties of the basic hydrogel ophthalmic lens. The water content increases with increasing amount of additive and decreases with addition of 0.2% ratio of nanoparticles. The refractive index is inversely proportional to the water content result. As a result of the antimicrobial test of the fabricated lens, the addition of carbon nanotubes shows an excellent antimicrobial effect. Therefore, it is considered that the fabricated lens can be applied as a functional material for basic ophthalmic hydrogel lenses.

Smoking is a disservice to not only for smokers who smoke, but also for nonsmokers due to smoke or smell. In particular, smoking harms health by increasing the discomfort associated with the smell generated by burning the cigarette, and giving rise to lung injury or cancer caused by smoke inhalation. The purpose of this study was to investigate the characteristics of various concentrations of nicotine, PM2.5, and heavy metals (As, Cr, Cd, Pb) generated by smoking according to the smoking intensity. When smokers smoked continuously, the amount of nicotine, PM2.5, Cr, and Cd produced by smoking increased proportionally and became statistically significant. However, As and Pb showed a different pattern from other materials, and the concentration increased by 2~3 times when 10 cigarettes were smoked. As for the change in PM2.5 for 12 hours immediately after smoking, about 70% of the particles were deposited on the floor or wall even in a sealed room where no ventilation was available, and the concentration naturally decreased. However, the remaining particles were found to remain in the air even though the time passed exceeded 12 hours.

Sulfide dissolved in wastewater is a potential source of hydrogen sulfide. Hydrogen sulfide is an odorous substance that causes civil complaints and is a dangerous substance that threatens the corrosion of structures and the safety and health of workers. The removal efficiencies of the chemical oxidant and the coagulants were compared to evaluate the removal of dissolved sulfide. Since the effectiveness may vary depending on the characteristics of the wastewater, water was used as a control, and 5 mg/L of dissolved sulfide was dissolved in water and sewage wastewater. When oxidant was used, the results showed a high sulfide removal rate in sewage wastewater than water, and the removal efficiency was enhanced with increasing oxidant concentration. Sulfide removal efficiencies after one hour after injecting oxidants H2O2, NaOCl, NaClO2 to sewage wastewater were 70%, 90%, and 100%, respectively. After the oxidants were administered four times, the removal was 90%, 100%, and 100%, respectively. In the case of sulfide removal with the oxidizing agent, the removal efficiency was NaClO2, NaOCl, H2O2 (highest - lowest). NaClO2 showed 100% removal efficiency within 10 minutes under all conditions (A condition, B condition), making it the most sewage effective agent in this study. In the case of the coagulants, 100% of the sulfides dissolved in water were removed in the first 10 minutes under all conditions. In sewage wastewater, FeCl2 and FeSO4 also showed 100% removal efficiency under all conditions after one hour, and FeCl3 showed 90% and 99% removal rates under A and B conditions, respectively. That is, the monovalent iron coagulants (FeCl2, FeSO4) were found to be somewhat more effective in the removal of sulfides in sewage wastewater than the divalent iron (FeCl3) coagulants. When the sulfides were removed with coagulants, FeCl2 had the highest removal efficiency followed by FeSO4 and FeCl3. Moreover, it was found that NaClO2 has the best reaction efficiency at the minimum reaction time and the reaction concentration.

In this study, real-time monitoring of air quality using a real-time mobile monitoring system was conducted to identify the emission characteristics and current status of air pollutants and odorous substances that are mainly generated in domestic dyeing industrial areas and to trace the pollutant sources. The concentration of toluene in the industrial area was detected up to 926.4 ppb, which was 3 to 4 times higher than that of other industrial areas. The concentration of methylethylketone was 124.7 ppb and the concentration of dichloromethane was 129.5 ppb. Acrolein concentration was highest at E point at 521.6 ppb, methanol concentration was highest at D point at 208.8 ppb, and acetone concentration was highest at M and N points at 549.3 ppb. The most frequently detected concentration of pollutants in the air quality monitoring results in the industrial area was, in descending order, toluene > methanol > acrolein > dichloromethane > acetone, which was similar to the chemical emissions used in the industrial area by the Pollutant Release and Transfer Register data. The concentration of odorous substances measured in real time was compared with the concentration of minimum detection, and the concentration of hydrogen sulfide was about 10 times higher than the concentration of minimum detection at A point, which was judged to be the main odorous cause of A point. In the future, if the real-time mobile measurement system is constructed to automatically connect wind direction/wind speed, PRTR (Pollutant Release and Transfer Register) data and SEMS (Stack Emission Management System) data, etc., it was judged that more accurate monitoring could be performed.

Asthma is a chronic diseases that restricts the air passage ways and which is thought to be caused by several factors such as genetics, obesity, mVOC, air pollution, allergens, and fungi. Domestic information on fungi in the indoor air in the houses of asthma patients in the spring and fall is rarely available. Thus, this study was carried out to investigate fungal concentration and diversity. Air samples were collected from the houses of 6 asthma patient in April and October of 2017 located in Seoul and Gyeonggi Provinces using an impaction method. The average concentrations of suspended fungi in the indoor air at the houses of adult asthma patient in October exceeded the 500 CFU/m3 level recommended by the Enforcement Managements of the Indoor Air Quality Control Act. A total of 70 fungi were isolated and identified. Four genera and 11 species were from the April sampling and 10 genera and 27 species were from the October sampling. Among the identified fungi, five species, Arthrinium marii, Penicillium austrosinicum, Penicillium concavorugulosum, Penicillium exsudans and Penicillium johnkrugii were found to be unrecorded species in Korea. The known properties of all identified fungi and the morphological and molecular characteristics of the five unrecorded species were described.

Outdoor air pollution with particulate matter has become more severe in Korea. Ambient particle concentration affects the indoor environment through various routes through building envelopes. In this study, we investigated particle exposure in residential buildings. Indoor and outdoor particle sources determined the indoor concentrations and particle exposure. This paper measured indoor particles and CO2 concentrations in two different apartment buildings and conducted the survey for 24 hours. The I/O ratio of the occupant awake period was higher than the asleep period. The I/O ratio in the awake period is 0.93-3.65, while the I/O ratio in the asleep period is 0.31- 0.76.Indoor peak events such as cooking or cleaning temporarily increase the I/O ratio and emit the indoor particle sources. Decay rate constant is 0.49-6.84 (1/h) in the indoor peak events during the operation of the exhaust hood and natural ventilation. The size range of 0.3-0.5 μm size is over half for the proportions of emitted particles (55.6%). Daily exposure is divided into indoor sources (45.2%) and outdoor sources (54.8%). We found the differences for the proportion of particle exposure. The ratio of daily exposure in particles for 0.3-0.5 μm size is 43.1 (indoor)/ 56.9 (outdoor) %. However, indoor sources are higher than outdoor sources for the ratio of daily exposure in particles for the 0.5-10.0 μm size.

The Odor-causing compounds from grilled meat restaurants are mainly ammonia, aldehydes, and volatile organic compounds (VOCs). Acetaldehyde is known to have the greatest odor contribution. This study examines the application of silica gel for acetaldehyde in gas stream. Heat-pretreated silica gel showed relatively good adsorption performance and at 150oC, its breakthrough capacity reached up to 51 mg/g. By using Thomas' dynamic model, which well estimated the adsorption performance in this study, the effects of inlet concentration and retention time on adsorption capacity were evaluated. The adsorbent saturated with acetaldehyde was regenerated by reducing the pressure, which was controlled by the vacuum pump. The design factors were found to be 10 sec−1 of space velocity, -184 kPa·hr of desorption condition, and 10 to 1 of the ratio of cross sectional area to the height for the fixed-bed. The cyclic operation of adsorption and desorption step in the fixed bed packed with silica gel appeared to have 7.0-8.8 mg/g of acetaldehyde removal capacity and 99% of regeneration.

In this study, the grid field olfactory odor method was supplemented to the domestic situation in the surrounding areas of a domestic science industrial complex. The actual condition of the occurrence of odor frequency in the field was then investigated over the first period of late spring to summer and the second period of autumn in 2017. The frequency of odor occurrence in the area around the science industrial complex was increased as odor discharge facilities in the nearby area were concentrated. The odor occurrence frequency of the total period was 0.09~0.28, that of the first period was 0.08~0.32, and that of the second period was 0.05~0.25. The odor occurrence frequency in summer was higher than in autumn. The frequency by which the measurement of odor occurrence by smell type was most dominant was mainly smell of chemicals, plastics, and livestock houses during the first period, and the smell of chemicals, burning gases, and plastics during the second period. And the frequency of each smell type was judged to be different according to season. The odor occurrence frequency was measured as higher than 0.15, which is the standard of Germany's odor frequency in an industrial area, and it was judged that measures for odor management in the region were necessary. Since most of the odor discharge facilities are non-continuous systems and the odor generation frequency is more important than the concentration of the minimum detection concentration, it was judged that the German grid method can reflect the odor occurrence characteristics of the odor complaints or receptors for a certain period of time compared to the domestic measurement method. In the future, it was judged that the field olfactory odor method would be able to replace the evaluation method of odor assessment in Korea with the survey method of odor assessment under actual conditions in areas where it is difficult to access the odor discharge source or the receptor where odor complaints occur.

The goal of this study was to measure the indoor and outdoor fine and ultrafine particulate matter concentrations (PM10, PM1.0) of some houses in Yeosu and in S university in Asan from March to September 2018. PM10 concentration in indoor air in Yeosu area was 18.25 μg/m3, while for outdoor air it was 14.53 μg/m3. PM1.0 concentration in indoor air in the Asan area was 1.70 μg/m3, while for outdoor air it was 1.76 μg/m3, showing a similar trend. Heavy metal concentrations in the Yeosu region were the highest, at Mn 2.81 μg/m3, Cr 1.30 μg/ m3, and Ni 1.11 μg/m3 indoors. Outside, similar concentrations were found, at Cr 3.44 μg/m3, Mn, 2.60 μg/m3, and Ni 1.71 μg/m3. Our analysis of indoor and outdoor PM concentrations in the Asan region, which was carried out using the MOUDI (Micro-orifice Uniform Deposit Impactor) technique, found that PM concentration is related to each particle size concentration, as the concentration of 18 μm and 18-10 μm inside tends to increase by 3.2- 1.8 μm and 0.56-0.32 μm.

In this study, 38 residents of the Jeonnam areas in Korea were assessed for their level of exposure to VOCs. The aim was to understand the difference in levels of indoor, outdoor, and personal exposure to VOCs (benzene, toluene, ethylbenzene) and a health effect assessment was conducted to determine whether there was any fatal cause from carcinogenic or non-carcinogenic elements from case and control group. Personal exposure to benzene showed a higher distribution than indoor and outdoor concentrations, and it was found that the average concentration of the case group was higher than that of the control group in all indoor, outdoor, and personal exposures. With regard to benzene, in the CTE, RME, and Monte-Carlo analysis, all subjects in the case group were seen to exceed the lifetime cancer risk of 10−6 defined by the US EPA and in the RME analysis the control group subjects were also seen to exceed the lifetime cancer risk of 10−6 defined by the US EPA. In the case of toluene, ethylbenzene on the CTE, RME, and Monte-Carlo analysis, the non-carcinogenic standard of 1 was not exceeded.

The emission of odor, characterized by the combustion conditions and biomass types resulting from the use of a biomass incinerator, was analyzed. The following biomass types were considered: bark, board waste, sawdust, wood flour, wood fiver, wastewater sludge, and timber wastewater. As a study method, the physico-chemical characteristics of each biomass type were analyzed to predict the potential substances that might be emited under incomplete combustion conditions. And, the emission components of odor emission by biomass were analyzed at the laboratory level using a combustion device. In addition, the characteristics of the contaminant (odor) emission per mixture ratio of biomass were analyzed in a stoker incinerator that is in operation in an actual establishment at a scale of 300 ton/day. In the biomass emission experiment using the combustion device at the laboratory level, the major substances such as Acetic acid, Styrene, Toluene, Benzene, Dichloromethane, etc. were analyzed, and these components were determined to increase odor index. VOCs measurement in the outlet of the stoker incinerator indicated that Acetaldehyde, Ethanol, Acetonitrile, Ethyl acetate, Toluene, etc. were detected as the major substances. These were similar to the emission substances presented by the experiment that had investigated emissions by biomass type. A study on the Effect of Operational Conditions in biomass stocker incinerator on the concentration of odorous materials emitted from stack showed a close relationship between the input by biomass type and urea, temperature in the incinerator, and the tendency to emit/produce odor.

이 연구의 목적은 중국의 사이버 산업스파이 활동을 분석하고 이에 대한 대응방안을 제언하는 것이다. 이 연구를 위해서 국내외 중국의 산업 기밀유출과 관련된 연구보고서 및 학술논문 분석을 통한 문헌연구방법과 중국 사이버 산업스파이 활동 사례를 수집해서 분석하였다. 분석결과, 국내의 첨단 산업기술 및 각종 산업분야의 전문인력 등 인적 자원이 중국으로 유출되고 있으며, 과거 오프라인 상에서 이루어지던 산업스파이 활동이 사이버 공간으로까지 전이 되고 있었다. 또한 일부 대기업을 제외한 대다수의 중소기업에서는 비용 등의 이유로 산업기밀 유출 방지를 위한 대응체계가 미흡하였다. 중국의 사이버 산업스파이 활동에 대한 대응방안으로 1) 사이버 산업스파이에 대한 추가적인 법률 검토 및 개선, 2) ‘망분리 사업’의 민간기업 적용 및 정부 주도의 정책적 사업 추진, 3) 사이버 산업기술유출에 대한 보안의식의 지속적인 제고를 제언하였다. 끝으로 이 연구의 한계 및 향후 연구를 위한 제언을 논의하였다.

A survey on the indoor air quality of schools was conducted on a total of 10 schools in each location, such as industrial zones, roadside zones and clean zones of the Jeonbuk Province. Regardless of their location, 75% of the schools were not suitable to the environmental standard, and five schools were inadequate in both the first and the second half measurement results. Compared to the public facilities survey conducted by the Jeollabukdo Institute Health and Environment Research from 2008 to 2016, the concentration of CO2, total airborne bacteria (TAB), and PM10, with the exception of HCHO, was higher in school classrooms than in any other public facilities. The correlations between pollutants and test items demonstrated that total airborne bacteria (TAB) were significantly correlated with the degree of ventilation, and the PM10 was correlated with the cleaning status, respectively. Although the other test items of indoor air quality in the school were measured in the same way as the public facilities measurement methods, the PM10 is applied in accordance with the simplified method. In order to investigate the difference between the measurement methods, the results were compared at the same point at the same time. When comparing the concentrations of PM10, the gravimetric method, which is a public facilities measurement method, showed a significant difference from the light scattering method, which is a method of measuring PM10 in schools. By comparison, it was confirmed that the light scattering method was measured lower than the gravimetric method. The light scattering method is useful for confirming the change of the particulate matter, but it is considered difficult to judge the concentration of the particulate matter in the classroom by the instantaneous measurement because of the potential error caused by high humidity, etc. Secondary pollution ions were measured at 17.1% ~ 40.5% in the industrial zone schools, 7.4%~27.4% in the roadside zone schools and 8.1%~21.8% in the clean zone schools, The percentage of pollution ions were not clearly distinguished by location.

This study was performed to evaluate the odor occurrence of offensive leather odor in a district in Gyeonggi-do, where Jeil industrial complex is located, and its residential district, by using olfactory field frequency measurement (Gird Method). In addition, we measured the composite odor. The target points were 9 spots in Jeil industrial complex and 12 spots in the residential district, and we conducted the measurements 13 times each spot. As a result, odor occurrence in descending order was investigated as follows, leather industry > drug industry > food industry. Moreover, odor exposure of the industrial complex exceeded the industrial zone standard of 0.15 (=German odor standard) in all 9 spots (average 0.78). In addition, odor exposure of the residential district exceeded the residential zone standard of 0.10 (=German odor standard) in 12 spots (average 0.78). All the composite odors were below 20 (industrial zone standard). However, as the odor intensity of the sampling site and the lab analysis data showed a large deviation, we found that much supplementation is needed of the odor analysis techniques in the equipment measurement methods.

최근 들어 서구유럽을 중심으로 폭력적·극단적 극우주의가 확산되고 그 위험수위가 증가하는 경향을 보이고 있다. 특히 폭력적 극우주의의 추세가 두드러지게 증가한 시기가 바로 2015년 이후 급증한 유럽의 난민유입과 관련이 있는 것으로 나타나고 있다. 서구유럽의 이‘난민위기’2015년 이후 유럽연합국가들에 다양한 측면의 사회적·정치적·경제적 위기를 불러오고 있다. 그리고 이러한 변화와 관련된 공포들이 서구유럽 국가들 내에 일반시민들 사이에서 폭력적이고 극단적인 극우주의를 지지 하는 사회현상을 증가시키고 극우주의를 배경으로 한 폭력행위가 증가되는 것과도 연관되어있는 것으로 분석되고 있다. 이와 관련해 EU의 난민 관리시스템과 이에 따라 학자들과 정부기관에서는 유럽 내의 폭력적·극 단적 극우주의의 원인들에 대해 이해하고 대응하려는 움직임을 보이고 있다. 대한민국의 세계에서의 위상의 증가로 인한 난민관리 및 수용에 대한 요구가 높아지는 가운데 이와 같은 난민위기와 서구유럽의 폭력적 극우주의의 부활은 국내에도 시사하는 바가 크다. 따라서 이 연구는 유럽국가들과 EU의 난민위기와 관련한 서구유럽의 폭력적 극단주의의 관련성에 대해서 분석하고, EU의 난민관리시스템 개선과 관련하여 연계된 법적, 제도적 문제점들과 이슈들을 분석하고자 한다. 이를 통해서 국내의 정책 및 입법 관련 논의점과 시사점을 제시하고자 하였다.

드론(무인항공기: UAV, Unmanned Aerial Vehicle)이 테러목적에 활용되는 사례가 점점 현실화되면서 드론을 이용한 테러에 대한 우려가 증가하고 있다. 2019년 9월 14일 사우디 석유시설에 대한 드론 공격은 큰 피해를 입으면서 드론이 국가 핵심시설을 타격할 수 있는 테러수단으로 악용될 가능성을 잘 보여주었다. 드론은 테러 목적 이외에도 사이버 해킹이나 다른 여러 범죄행위에도 이용될 수 있다. 소형 드론은 전문지식 없이도 공중 이동과 원격 조종을 바탕으로 안전·보안 위협, 사생활 침해 등의 범죄 행위에 쉽게 사용 가능하기 때문에 그 위협성이 더욱 우려 된다. 이와 관련 하여 테러 등 각종 범죄사용 우려와 함께 각국에서는 드론에 의한 신규 범죄예방책을 마련 중이다. 현재 한국에서도 여러 법률과 전파차단장비의 운용, 조종자 처벌 및 제지, 비행금지 또는 제한구역 설정, 비행시간제한 등의 조치를 취하고 있으나 미흡하다. 드론 보급의 대중화에 따른 불법 드론 비행사례증가 및 드론을 이용한 각종 테러 위 험성이 상존하여 이에 대한 안전대책 마련이 필요하다. 이와 같은 문제 인식에 근거하여 이 글에서는 드론 테러에 대한 전략적 이해를 제시하고 드론 테러의 현황과 미래의 추이를 평가하며, 이를 바탕으로 정책, 법률적 대응을 위한 방향성과 몇 가지 방안을 제안한다. 미래 폭력은 분산 공격 능력(the distribution of offensive capability), 취약성의 분산 (the distribution of vulnerability), 그리고 분산된 방어(the distribution of defense)를 특징으로 한다. 드론 테러는 이러한 미래 폭력의 특성이 잘 반영된 대표적인 구체적 사례에 해당한다. 드론 테러가 야기하는 공격능력의 분산과 취약성의 분산이 제기하는 딜레마에 대한 효과적인 대응은 따라서 방어의 분산을 통해 모색될 수 있다. 이 글에서 제시하는 몇 가지 전략적, 정책적, 그리고 법률적 모색들은 그러한 노력의 일환이다.

대한민국은 세계 최초로 5G기술을 상용화하는데 성공하였다. 일부에서는 미비한 기술로 너무 서둘렀다는 비판도 제기하고 있지만 ‘경제전쟁’이 라는 용어가 일상화된 국제질서에서 불가피한 선택이었음은 분명하다. 5G기술은 우리의 혼자 힘으로 이룩한 것이라고 보기 곤란하다. 그 안에는 여러 국가의 기술과 제품이 혼재되어 있다. 이는 보안취약점을 노출 하는 위험성을 가지고 있다. 이미 여러 차례 북한으로부터 사이버공격을 받은 우리에게 5G는 역설적이게도 새로운 위협으로 다가올 수 있다. 미국이 중국의 특정회사를 지목하여 퇴출에 가까운 조치를 취한 것은 이러한 위험성을 새롭게 인식시키는 계기가 되었다. 최근 정부는 이러한 사이버안보문제에 대한 대책으로 지난 4월 청와대 국가안보실에서 ‘국가사 이버안보전략’을 발표했다. 5G기술에 필요한 기술이나 제품을 다른 국가의 기업에 의존할 수밖에 없는 것이 어쩔 수 없는 현실임을 감안한다면, 이를 적절하게 관리하고 통제하기 위해 일정한 국제협력이 반드시 필요하다. 5G표준화를 선도하여 국가경쟁력을 높이고 미래산업을 육성하기 위해서도 더욱 필요하다. 그러나 반대로 국제협력을 통해 5G기술의 취약점이 노출되지 않도록 조심해야한다. 결국 초연결로 만들어질 5G사회를 안전하게 관리하고 관련 산업분야를 발전시키기 위해서라도 국가의 사이버안보를 관리하는 주체가 마련되고 이를 법제화해야한다. 이를 위해 체계적인 관리방안을 마련 해야한다. 이미 우리의 삶에 밀접하게 다가오기 시작한 AI기술과 자율주행기술은 과거 우리가 경험했던 사이버테러와는 전혀 다른 피해규모를 가져올 개연성이 충분하다. 이를 미리 예방하고 대비하기 위해서 더욱 안보적인 관점으로 이에 접근할 필요성이 있다. 현재와 같이 관련기관이 모여 피해상황을 파악하고 해결방안을 마련하는 방식으로는 적절한 대응이 어렵다. 이제 시작된 5G의 상용화로 발생할 수 있는 안보상 문제점 등을 미리 파악하고 현장에서 즉시 대응하는 방식으로 조직체계를 재정비하고 이를 뒷받침하는 법률을 제정할 시점이다.
