산업기술 보안 이슈는 대내외적으로 급격한 변화를 겪고 있다. 미국 등 선진국은 글로벌 가치사슬 및 해외자본 이동과 갈등을 빚으면서도 자국의 핵심 기술 보호를 위한 대응전략을 수립하고 있으며, 국내 또한 중장기 산업경쟁력 속에서 산업안보이슈를 접근하고 있다. 본 연구에서는 국내 산업보안 관련 이해관계자들을 대상으로 산업보안 생태계 정책인식 조사를 통해 주요 이슈를 도출하였다. 조사결과, 이해관계자 모두 산업보안의 중요성에 대해 인식하나 아직까지 국가전체 보안관리 역량은 낮다고 인식하고 있으며, 국가핵심기술은 국가에서 보다 책임을 지고 관리할 필요성이 있음을 제기하였다. 3라운드에 걸친 종합 델파이 조사를 기반으로 '산업보안 컨트롤타워 중심 시스템 체계화', '보안전문기업 기술력 강화 및 보안인력 양성', '인력 및 자본을 통한 기술유출 방지제도 개선', '연구개발 과정에서의 연구보안 및 선제적 기술보호 강화'를 정책개선 과제로 제시하였다. 본 연구가 산업보안 현장의 수요를 반영한 증거 기반 연구로서 관련 정책수립의 기초가 될 수 있기를 기대한다.

This research topic evaluates the effectiveness and importance of environmental protection in the 21st century in light of the increasing demand on the earth's natural resources and the pressures on economic and industrial development to provide dynamic power. As the world and our fellow citizens become more conscious of environmental protection, companies are under greater pressure whilst pursuing economic growth. Therefore, domestic manufacturers have been devoting efforts to promote environmental management. This research conducts survey using questionnaires on the operational performance of the manufacturers who have ISO 14000 series accreditation and certification. The survey considers five dimensions/functions within a manufacturer, financial management, human resources management, production management, and marketing management. A total of 35 indices are used for analysis of the effects that the location, history, industry, number of employees, amount of capital, and revenue may have on the performance. This research targets the manufacturers approved of ISO 14000 series certification by Environment Administration Association. The statistical methods deployed are descriptive statistics, T-test, and single factor analysis of variance used for analysis. The conclusions reveal that a certain level of performance has been achieved in every dimension. After T-test, all the indices have reached a significant level. The indications are that ISO 14001 benefits all manufacturers the level of benefits however varies from company to company.

최근 배전계통은 정부의 녹색성장 정책으로 태양광, 풍력발전 등과 같은 분산전원의 보급률이 지속적으로 증가되고 있는 실정이다. 이러한 분산전원의 연계로 기존 배전계통의 조류흐름은 단방향(One-direction)에서 양방향(Bi-direction)으로 변화되고, 고장전류의 증 감이 발생하는 등, 다양한 변화가 생겨 배전계통의 운용상에 여러 가지 문제점들이 발생할 가능성이 커지고 있다. 따라서 본 논문에서는 분산전원의 배전계통 연계에 따른 보호기기의 정정 및 양방향 보호협조 검토가 가능한 보호협조 평가알고리즘과 실제의 사고전류 값을 이용한 개선된 T-C곡선 알고리즘을 제안하고, 이 알고리즘을 바탕으로 양방향 보호협조 평가시스템을 개선하였다. 또한 평가시스템을 이용하여 배전계통을 모델링하고, 분산전원 연계 시 보호기기들 간의 보호협조를 검토하여, 분산전원이 연계된 경우 배전계통에 발생할 수 있는 기술적인 문제점들을 분석하여 그 방안을 제시하였다.

We present selfie stick case design, which can protect upper part of Selfie Stick. Many of current products are damaged when it is carried without cases, especially upper part of the product, because protection case is irrelevant to handle in urgent or frequent use of the product. To solve this problem, we design the case part which is attached to stick. For designing the part, we considered functionality, aesthetics, portability and profitability.

Herein,the Neodymium ion ($Nd^{3+}$) doped CoAl-LDH have been successfully prepared via co-precipitation method and was used as a precursor of Nd-doped CoAl-mixed metal oxides (MMO). The photocatalytic activity of doped LDH and MMO was investigated in the degradation of an azo dye, C.I. Acid Red 14, under visible light irradiation. DRS and PL analysis demonstrated decreasing in the band gap energy and recombination of photo-induced charge carriers of Nd-doped LDH and MMO compared with the pristine CoAL-LDH. Due to significant difference in photocatalytic performance. A power law empirical kinetic model was obtained for predicting the photocatalytic degradation efficiency.

Anti-graffiti coatings have become more important. These layers must guarantee excellent corrosion protection properties, and graffiti must be easily removable, without reducing protection and aesthetic properties. In this study, anti-graffiti and corrosion behavior of two anti-graffiti polyurethane powder coatings were studied. These layers were deposited on aluminum substrate, with two different surface finishes, smooth, and wrinkled. The action of four different removers are investigated. Graffiti were drawn on coatings by means of red acrylic spray paint. Methyl-ethyl-ketone (MEK) and a "commercial" remover were the most effective solvents, in terms of graffiti removal capability, producing limited change in aesthetical surface aspect for smooth finishing. The wrinkled surface was less resistant. Corrosion protection properties, after removal action and contact with the remover, were evaluate by electrochemical impedance spectroscopy. After approximately 5 hours, coatings were no longer protective due to formation of defects. To simulate the weathering effect, UV-B cyclic test (4 hours of UV exposure followed by 4 hours of saturated humidity at $50^{\circ}C$) were performed for 2000 hours. Gloss and color changes were measured, and electrochemical impedance spectroscopy measurements were performed after aging and graffiti removal.

최근 기업이 보유한 산업기밀은 영업비밀보호법, 산업기술유출방지법 등 다양한 산업보안 관련 법률에 의해 보호 받고 있다. 그러나 그러한 보호에도 불구하고 산업기밀의 침해 및 유출사고는 해마다 증가하고 있다. 한국산업기술보호협회의 조사에 따르면 산업기밀 유출 예상 피해액은 연평균 "50조 원"으로 추정되며 이는 중소기업 4,700여 개의 연 매출액과 맞먹는 금액이다. 이처럼 산업기밀 유출은 국가와 기업의 경쟁력은 물론이고 경제적으로도 심각한 피해를 초래한다. 하지만 산업기밀 유출범죄에 대한 투자와 노력은 피해규모에 비해 한 없이 부족한 수준이며 일부 대기업을 제외한 대부분의 기업들이 산업기밀 유출보안을 위한 별도의 조직, 인력, 예산이 없어 산업기밀 유출에 대한 대응체계가 부족한 것이 현실이다. 본 논문은 국내외 산업기밀 유출범죄 분석을 통하여 산업기밀 유출에 따른 피해실태를 파악하고 발생원인, 유출경로 등 다양한 분류체계를 통하여 산업기밀 유출범죄에 대한 전반적인 흐름을 파악하여 관련 연구에 대한 기초자료가 될 것으로 기대한다.

Life Cycle Assessment (LCA) aims to analyze possible impact upon manufacturing process and availability of products, and also study the environmental considerations and potential influence during entire life cycle ranging from procurement, production and utilization to treatment (namely, from cradle to tomb). Based on high-density polyethylene (HDPE) pipe manufacturing of company A, this case study would involve evaluation of environmental influence during the production process. When the manufacturing process has been improved during "production process" and "forming cooling" stage, it is found that capital input on "electric power" and "water supply" could be reduced, thus helping to sharpen the competitive power of company A, and also ensure sustainable economic and industrial development in accordance with national policies on environmental protection.
