기업 간의 기술 경쟁이 치열해 짐에 따라 기술보호의 중요성은 날로 높아지고 있다. 그러나 우리나라의 기술유출 현황을 살펴보면 중소기업의 기술보호 수준은 취약한 것으로 나타나고 있다. 중소기업의 기술유출은 지속적으로 발생하고 있으며, 유출에 따른 피해는 중소기업에게는 더욱 치명적일 수 있다. 이에 정부에서는 중소기업을 위한 다양한 기술보호 지원제도를 운용하고 있다. 그러나 이러한 지원제도에도 불구하고 중소기업들의 관심과 이용은 저조한 편이다. 본 연구에서는 우리나라의 중소기업 기술보호를 위한 주요 지원 제도들의 현황을 살펴보고, 지원제도에 대한 기업들의 인식과 기대 효과를 실증적으로 분석한다. 실증분석 결과를 바탕으로 지원제도의 인식 제고와 활성화를 위한 개선방안을 논의한다. 연구 결과는 국내의 중소기업 기술보호 지원제도의 효용성 증대와 활용성 제고를 통한 중소기업 기술보호 강화에 기여할 수 있을 것이다.

최근, 대용량의 태양광전원이 연계된 배전계통은 기존의 단방향과 달리 양방향의 조류가 발생하고, 태양광전원의 연계위치 및 고장위치에 따라 사고전류의 크기와 방향이 변하여, 보호기기간의 협조시간차가 충분히 확보되지 않는 문제점이 발생할 수 있다. 또한, 태양광전원을 고려하지 않은 기존의 보호기기 정정치를 그대로 적용하고 있어 보호기기간의 협조시간차를 확보하기 어려운 상황이 발생하고 있다. 따라서 본 논문에서는 태양광전원이 연계된 선로에서 고려할 수 있는 3가지 Case의 보호기기 정정치 운용모드를 제시하고, 이를 바탕으로 태양광전원의 용량에 따른 최적의 보호협조 시간을 도출할 수 있는 알고리즘을 제안한다. 한편, 이를 바탕으로 보호협조 전용소프트웨어인 Off-DAS를 이용하여, 태양광전원이 연계된 배전계통을 모델링하고, 보호기기(변전소 계전기, 리클로저(Recloser), 고객계전기, 태양광전원 고객계전기)간의 협조시간차 특성을 분석한다. 실 계통을 대상으로 시뮬레이션을 수행한 결과, 본 논문에서 제시한 보호기기의 정정치 운용 모드와 정정치 산정 방식이 태양광 전원이 연계된 배전계통 보호기기간의 협조시간을 안정적으로 확보할 수 있음을 알 수 있었다.

Background: Salmonella enteritidis (SE) was the main cause of the pandemic of foodborne salmonellosis. The surface of eggs' shells can be contaminated with this bacterium; however, washing them with sodium hypochlorite solution not only reduces their flavor but also heavily impacts the environment. An alternative to this is surface sterilization using low-energy electron beam. It is known that irradiation with 1 kGy resulted in a significant 3.9 log reduction (reduction factor of 10,000) in detectable SE on the shell. FAO/IAEA/WHO indicates irradiation of any food commodity up to an overall average dose of 10 kGy presents no toxicological hazard. On the other hand, the Food and Drug Administration has deemed a dose of up to 3 kGy is allowable for eggs. However, the maximum dose permitted to be absorbed by an edible part (i.e., internal dose) is 0.1 Gy in Japan and 0.5 Gy in European Union. Materials and Methods: The electron beam (EB) depth dose distribution in the eggshell was calculated by the Monte Carlo method. The internal dose was also estimated by Monte Carlo simulation and experimentation. Results and Discussion: The EB depth dose distribution for the eggshells indicated that acceleration voltages between 80 and 200 kV were optimal for eggshell sterilization. It was also found that acceleration voltages between 80 and 150 kV were suitable for reducing the internal dose to ≤ 0.10 Gy. Conclusion: The optimum irradiative conditions for sterilizing only eggshells with an EB were between 80 and 150 kV.

The policy change in the Data 3 Act is one of the issues that should be noted at a time when non-face-to-face business strategies become important after COVID-19. The Data 3 Act was implemented in South Korea on August 5, 2020, calling 'Big Data 3 Act' and 'Data Economy 3 Act,' and so personal information that was not able to identify a particular individual could be utilized without the consent of the individual. With the implementation of the Data 3 Act, it is possible to establish a fair economic ecosystem by ensuring fair access to data and various uses. In this paper, the law on the protection of personal information, which is the core of the Data 3 Act, was compared around Korea, the European Union and the United States, and the implications were derived through network analysis of keywords.

In this paper, an OPS(Optical Protection Socket) unit is designed and prototyped for the application in the optical CPN(Customer Premises Network). The OPS unit, which plays an important role in the CPN for the enhanced network reliability, is consisted of $1{\times}2$ optical fiber splitter, combiner, and $1{\times}1$ optical switch to be a hybrid-typed unit. Various considerations, about power burget and optical information loss have given the most practical design for OPS. From the measurement of the realized OPS unit, it has proved such as the pertinent switching delay time with minimum data loss, the perceptive ability on the ONU degradation, the switching ability on the ONU malfunction.

Improved properties of second electron emission was evaluated by assemble of 4 inch PDP panel. MgO protection layers were deposited and examined by using both pellets made of extremely pure MgO single crystals and sintered pellets using MgO nano powders. $\gamma$ coefficients higher than 0.11 were obtained from the panel by adopting dopant-controlled MgO single crystals. Especially the MgO layer deposited by sintered pellets made of nano powders showed the higher $\gamma$ coefficients at the operating voltage above 200 volts.

[ $SF_6$ ] gas that is used as a protective cover gas for Mg and Mg alloys during melting and casting has extremely high greenhouse effect. CaO added Mg alloys could maintain their original mechanical properties and original abilities such as fluidity and hot tearing susceptibility. The ignition temperature increased with increasing CaO addition under ambient atmosphere and nitrogen atmosphere. The minimum amount of $SF_6$ gas decreased by 0.13 wt%CaO added AZ91D Mg alloy in the sealed condition.

By integrating WDM to OPS unit which plays an important role for the reliability of CPN, we made it possible to provide CATV, VOD, and high-speed data services simultaneously and to meet the requirements for new services in the future. For the design of optimal system, the link analysis of power budget has been performed. Also, the prototyped system has been tested with STM-1 level signals to confirm functions such as transmission, distribution, and protection. The results proved that when occurred out-of-order or recovery of ONU, the system did the pertinent switching with minimum loss for high-speed data services. Also for video distribution services, the system has distributed STM-1 level signals successfully.

Nuclear power plant (NPP) is currently considered as one of the most reliable power sources. However, 182 of them are considered decommissioned and inactive including the one in Bataan, Philippines. The aim of this study was to investigate the acceptance of the reopening of Bataan Nuclear Power Plant (BNPP) by integrating the Theory of Planned Behavior and Protection Motivation Theory. A total of 815 Filipinos answered an online questionnaire which consisted of 37 questions. The Structural Equation Modeling (SEM) indicated that knowledge towards nuclear power plants was the key factor in determining people's acceptance towards NPP reopening. In addition, knowing the benefits would lead to positive perceived behavioral control (PBC) and attitude towards intention. Results showed that PBC and attitude are mediators towards the acceptance of people regarding the reopening of BNPP. If an individual's knowledge gravitates towards the perceived risk, then this can lead to the negative acceptance of the NPP reopening. On the other hand, if an individual's knowledge gravitates towards the perceived benefits, then this will lead to positive acceptance. This study is the first study that explored the acceptance of the reopening BNPP. Finally, the study's model construct would also be very beneficial for researchers, government, and even private sectors worldwide.
