It is necessary to fabricate uniformly dispersed nanoscale catalyst materials with high activity and long-term stability for polymer electrolyte membrane fuel cells with excellent electrochemical characteristics of the oxygen reduction reaction and hydrogen oxidation reaction. Platinum is known as the best noble metal catalyst for polymer electrolyte membrane fuel cells because of its excellent catalytic activity. However, given that Pt is expensive, considerable efforts have been made to reduce the amount of Pt loading for both anode and cathode catalysts. Meanwhile, the atomic layer deposition (ALD) method shows excellent uniformity and precise particle size controllability over the three-dimensional structure. The research progress on noble metal ALD, such as Pt, Ru, Pd, and various metal alloys, is presented in this review. ALD technology enables the development of polymer electrolyte membrane fuel cells with excellent reactivity and durability.

바이오 의약품 생산과정의 대부분 공정에서 분리막이 사용되고 있다. 분리막 공정은 다른 공정의 전처리, 공정 자 체의 불순물 분리, 바이러스 제거, 목표 생성물 농도 조절 및 완충 용액 교환 등에 사용된다. 인체에 사용하는 바이오 의약품 의 바이러스 오염은 심각한 임상 결과와 직결되는 민감한 문제이기 때문에 바이러스 필터는 제품의 효능과 안정성을 보장하 기 위해 중요한 역할을 한다. 바이러스 필터는 일반적으로 표면 개질된 PVDF, PES, CRC 등 다양한 고분자로 만들어진 복합 다층 구조를 가지고 있다. 제조업체에 따라 대칭(symmetric) 또는 비대칭(asymmetric) 등 다른 기공 구조와 형태를 가지고 있 으며, 주름막, 평판 시트 또는 중공사 형태로 사용된다. 바이러스 필터는 Asahi Kasei 를 비롯해 Millipore, Pall, Sartorius 등 몇몇 해외 업체들이 독점적으로 국내에 공급하고 있다. 바이러스 필터를 대체하려면 검증작업을 통해 규제기관의 승인을 받 는 등 상당한 시간과 비용이 소요된다. 최근 일본의 수출규제로 국산화가 중요해진 만큼 제거 성능 고도화 등 선제적으로 기 술자립도를 높여가야 한다.

폴리글리세린지방산에스터 비이온계면활성제는 식품 등에 오래전부터 사용해 왔으며 PEG계 비이온계면활성제의 안전성 문제에 대한 대안으로 제시되고 있다. 폴리글리세린지방산에스터 계면활성제는 친수기인 폴리글리세린과 친유기인 지방산을 결합시켜 합성된다. 친수기인 폴리글리세린은 글리세린, 글 리시돌, 에피클로로히드린 등을 이용하여 중합되는데 폴리글리세린 중합반응의 주요 이슈는 분기·환상형태가 아닌 직쇄형태의 폴리글리세린의 함량을 높이고 중합도의 분포를 좁히는 것이다. 친수기인 폴리글리세린에 지방산계 친유기를 결합시키는 방법에는 에스터화 반응 등의 화학적 합성법과 지방분해효소를 이용한 효소 합성법이 있다. 폴리글리세린지방산에스터 합성의 주요 이슈는 에스터화정도를 조절하면서 반응 수율을 높이고 부반응을 억제하는 것이다.

The transition from “More-of-Less” markets (economies of scale) to “Less-of-More” markets (economies of scope) is supported by advances of disruptive manufacturing and reconfigurable-supply-chain management technologies. With the prevalence of cyber-physical manufacturing systems, additive manufacturing technology is of great impact on industry, the economy, and society. Traditionally, backbone structures are built via bottom-up manufacturing with either pre-fabricated building blocks such as bricks or with layer-by-layer concrete casting such as climbing form-work casting. In both cases, the design selection is limited by form-work design and cost. Accordingly, the tool-less building of architecture with high design freedom is attractive. In the present study, we review the technological trends of additive manufacturing for construction-scale additive manufacturing in particular. The rapid tooling of patterns or molds and rapid manufacturing of construction parts or whole structures is extensively explored through uncertainties from technology. The future regulation still has drawbacks in the adoption of additive manufacturing in construction industries.

High-entropy alloys (HEAs) are generally defined as solid solutions containing at least 5 constituent elements with concentrations between 5 and 35 atomic percent without the formation of intermetallic compounds. Currently, HEAs receive great attention as promising candidate materials for extreme environments due to their potentially desirable properties that result from their unique structural properties. In this review paper, we aim to introduce HEAs and explain their properties and related research by classifying them into three main categories, namely, mechanical properties, thermal properties, and electrochemical properties. Due to the high demand for structural materials in extreme environments, the mechanical properties of HEAs including strength, hardness, ductility, fatigue, and wear resistance are mainly described. Thermal and electrochemical properties, essential for the application of these alloys as structural materials, are also described.

This paper examines the trend of restructuring and direction of management response in the Large Purse Seine Fishery. The large-scale fishing industry is one of the most popular fishing areas in the coastal area, and it has been developed by providing exclusive supplies of many types of catchy fish, such as mackerel and horse mackerel through physical productivity in fleet operations. However, the Large Purse Seine Fishery has been declining in profitability due to the deterioration of the business environment since 2000. It is at a crossroads whether it will disappear or regenerate as it is. The Large Purse Seine Fishery's current problems are: firstly, the continued deterioration of the fishery business balance and worsening labor problems, secondly, insufficient freshness management and quality control after landing, and thirdly, import competition. The fourth is the intensification of the market competition, which is the evolution of fishing variability and the increase in the proportion of small fish. The fifth is the reduction of the operating fishing ground due to the suspension of mutual fishing in Korea and Japan. To address these problems and suggest management response directions for the survival of large-scale fishing businesses is as follows. First, a sustainable production system should be established through strengthening resource management and promoting international fisheries cooperation. Second, the profitability of fishing management should be improved by introducing a low-cost supplier system and securing a stable labor force. Third, we should improve the leading and quality control of catch, improve the high value-added value of catch through brand development, and secure competitive advantage with imported produce. Finally, the government should establish a cooperative system among private sector, government, and research institutes to push ahead with these tasks and strengthen the competitiveness of the front and rear industries.

화훼작물의 새로운 품종 개발과 특성을 개선하기 위해 교잡 및 돌연변이 육종과 같은 기존 기술에서 유전자변형기술에 이르기까지 다양한 육종 기술이 사용되고 있으며, 특히 화훼류의 유전자변형기술은 화색변형, 화형 및 형태변형, 개화시기 조절, 꽃 수명연장, 내환경성, 내병성, 내충성 등의 목적으로 이루어지고 있다. 국내에서의 GM 화훼류 연구는 2000년대부터 진행되었고, 현재는 장미, 국화, 카네이션, 페튜니아 등을 대상으로 형질전환체를 개발하고 있다. 호주의 Florigene사에서 개발한 푸른 카네이션이 상업화되면서 일본 SUNTORY사 의 파란색 장미 그리고 호주 Florigene사의 시들지 않는 카네이션이 개발되어 상용화되고 있으며, 더 많은 품종 개발과 판매 시장이 증가하고 있는 추세이다. 이처럼 GM 화훼작물에 대한 연구성과는 급속도로 발전하고 있으며, 국내에서도 생명 공학 기술을 기반으로 형질이 우수하고 소비자의 선호도가 높은 새로운 화훼 신품종 개발로 수출확대를 도모함으로써 농가 소득 향상을 기대할 수 있을 것으로 판단된다. 본 보고에서는 국내외에 최근 보고된 GM 화훼작물의 형질전환체 연구개발 성공 사례들을 소개하고, 그 요인 분석을 통해 향후 더 성공적인 GM 화훼작물 개발 전략을 수립하는데 도움이 되고자 한다.
