바이오매스에서 얻어지는 바이오차는 토질 개량제와 탄소 격리제로 제한적인 분야에서 성공적으로 사용되고 있다. 현재 산업전반에서 CO2 에 의한 환경에 부정적인 영향을 완화시키고 지속가능성을 증진시키기 위한 연구가 활발히 진행되고 있다. 이에 본 연구에서는 고탄소 바이오차를 탄소 격리제 또는 시멘트의 혼화재로써 활용 가능성을 평가하고자 하였다. 견목재에서 얻어진 바이오차를 혼화재로 사용하여 시멘트 배합조건을 달리하면서 모타르의 압축강도, 마이크로구조, 압축강도, 유동성, 중량감소와 같은 화학적, 물리적 재료성질을 평가하였다. 또한 플리이애쉬를 사용한 모르타르의 역학적 특성과 비교 평가하였다.

The fishing industry in Europe has faced environmental, economic, and social challenges. Since the early 2000s, a key tool in addressing these challenges has been information and communication technology (ICT), which has helped to modernize fishery systems in European Union (EU) countries. The ICT used in EU fisheries can be categorized broadly as 1) macro-technologies such as satellite and other remote sensing technologies in combination with geographical information systems, 2) micro-technologies adapted for fishing vessels such as echo sounders, ship navigation devices, and mobile communication devices to connect fishermen and consumers, and 3) onshore micro-technologies related to internet technology and mobile devices. The European Monitoring Center on Change has used ICT to effectively manage fisheries bio-resources. This use of ICT has contributed to the development of sustainable and competent fisheries in the 2000s, even though the knowledge-sharing practices involved are contrary to the long tradition of autonomy within the fishery industry.

Song-Gang^® bio-stone (SGS) is a microporous crystalline hydrated aluminosilicate which has found various applications because of their very unique physiochemical characteristics such as ion exchange and absorptive-desorptive properties. Significant progress has been made in recent years on applications of these inorganic adsorbents in different industries including agriculture, aquaculture, water and wastewater treatment. This review article intends to summarize the published reports on the applications of SGS in aquaculture industry. SGS application as a feed additive to enhance fish growth and promote their health and nutritional parameters is the most important discussed areas. According to the technical data that are discussed in this review, SGS should be considered as a material with tremendous potential for application in the aquaculture industry. Considerable amounts of research works are under way to explore other opportunities for application of SGS to benefit aquaculture industry.

The field of synthetic biology has emerged in response to the ongoing progress in the life sciences. Advances have been made in medicine, farming, eating, making materials, and more. Synthetic biology is the exploration of using living organisms to create new organisms. By manipulating specific genes to express targeted proteins, proteins can be created that are both productive and cost-effective. Solid-phase extraction (SPE) and liquid-liquid extraction (LLE) are employed for protein separation during the production process involving microorganisms. This study centers on Scanning Probe Microscopy (SPM) to showcase its utility in the food industry and food management. SPE is predominantly utilized as a pretreatment method to eliminate impurities from samples. In comparison to LLE, this method presents benefits such as decreased time and labor requirements, streamlined solvent extraction, automation capabilities, and compatibility with various other analytical instruments. Anion exchange chromatography (AEC) utilizes a similar methodology. Pharmaceutical companies utilize these technologies to improve the purity of biopharmaceuticals, thereby guaranteeing their quality. Used in the food and beverage industry to test chemical properties of raw materials and finished products. This exemplifies the potential of these technologies to enhance industrial development and broaden the scope of applications in synthetic biology.

Fruits and vegetables reportedly have a protective effect against hyperlipidemia and oxidative disease. Accordingly, this study aimed to investigate the lipid-lowering effect and antioxidative capacity of persimmon leaf extract (PLE) in rats fed a high-cholesterol diet. Male rats were fed a high-cholesterol (1% wt/wt) or high-cholesterol diet supplemented with Lovastatin (0.02% wt/wt) or PLE (0.2% wt/wt) for 5 weeks. The concentration of plasma total cholesterol was significantly lower in the PLE group than in the lovastatin group. However, the concentration of plasma HDL-cholesterol and the ratio of HDL-cholesterol/total-cholesterol (%) were significantly higher in the PLE group than in the control group. The PLE supplement also significantly lowered the contents of hepatic cholesterol and triglyceride. In comparing fecal sterol contents, the PLE group saw a significant increase of both neutral and acidic sterol compared to the other groups. The PLE supplement significantly lowered plasma GOT and GPT activity, which ave indices of hepatic toxicity. Plasma TBARS concentration was significantly lower in the PLE group than in the control group, while hepatic TBARS level was not significantly different between the groups. In a comparison of hepatic antioxidant parameters, SOD, catalase and GSH-Px activity were significantly higher in the PLE group than in the control group. However, the PLE supplement significantly towered antioxidant enzyme activity in the erythrocyte. Furthermore, these results suggest that supplementation of PLE promoted the excretion of fecal sterols, thereby leading to decreased absorption of dietary cholesterol. In addition, PLE may play an important role in regulating antioxidative capacities by altering SOD and ChT activity.

본 연구는 대표적인 지식기반산업인 생명의료산업의 첨단의료복합단지 조성정책을 대상으로 하여 정책형성과정을 분석하고자 한다. 첨단의료복합단지는 다양한 분석요소와 속성들을 내포하고 있기 때문에 국내외 정치적 경제적 사회적 환경변화에 따른 정책형성과정을 Kingdon(1984, 1995, 2003)의 '정책흐름모형'을 적용하여 분석하였다. 2005년 8월 의료산업선진화위원회가 출범한 시기에서 2008년 3월 '첨단의료복합단지특별법'이 제정되기까지 정책형성 과정을 대상으로 하였다. 분석결과 첨단 의료산업분야의 정책형성 과정은 여러 요인들과 정책흐름들이 간여되어 있으며, 특히 정책의제가 정부의제로 공식화되는 법제화의 과정은 정책선도자 뿐만 아니라 다양한 이해관계자의 역동적인 역할에 의하여 진행된다는 점을 조명하였다.

This study was carried out to define the optimum drying conditions for Lycium chinense Miller as a useful healthy food, because recently the cultivation area and yield of this fruit are increased. The experiments of two varieties were performed at the temperature of $45^{\circ}C$, $50^{\circ}C$, $55^{\circ}C$ and $60^{\circ}C$. The drying ratio was the slowest and quality was the best at the drying temperature of $45^{\circ}C$. The drying temperature was higher, drying ratio was more faster and the quality became worse. The difference of drying ratios between the varieties was insignificant. The energy consumption per hour was the minimum at the drying temperature of $45^{\circ}C$, but the total energy consumption was the maximum for the long drying time. Also, the energy consumption at the drying temperature $50^{\circ}C$, $55^{\circ}C$ and $60^{\circ}C$ was not very different from others. Considering the drying ratio, quality and energy consumption, the drying time of 36 hours at the drying temperature of $50^{\circ}C$ was the most optimum condition.
