석유 및 천연가스를 대체하는 자원으로 석탄이 유망하다고 전망하고 있다. 미국에서는 6대 파괴력이 있는 기술로 청정석탄기술이 선정되었고, 한국에서도 15대 그린에너지 중 하나인 청정연료에 석탄전환기술이 포함되어 전략로드맵이 작성되고 있다. 국내에서 추진되고 있는 석탄기술은 석탄가스화를 기반으로 하고 있다. 석탄가스화는 고체연료인 석탄을 $1000^{\circ}C$ 이상의 고온에서 산소와 반응시켜 일산화탄소와 수소가 주성분인 합성가스로 전환하는 기술이다. 석탄을 가스화하면 석탄에 포함된 불순물을 쉽고 완벽하게 제거할 수 있으며 특히 CO2 제거를 값싸게 할 수 있어 청정화가 가능하다. 최근 고유가를 겪으면서 열량이 높은 고급탄의 확보가 어려워지면서 가격이 낮고 수급이 용이한 저급탄을 활용하는 기술의 수요가 발생되어 국내에서 기업을 중심으로 저급탄을 고효율로 가스화하는 기술 개발이 시도되고 있다. 정제된 석탄가스는 성분을 조절하여 촉매에 의해 메탄으로 전환시킬 수 있고, 이렇게 제조된 가스를 합성천연가스(SNG)라 한다. 값싼 저급탄을 사용하면 SNG를 천연가스보다 저렴하게 생산할 수 있다. 국내 기업이 SNG 제조 실증시설을 도입하고, 동시에 핵심기술인 SNG 합성반응공정을 개발하는 사업을 추진하고 있다. 석탄가스를 촉매반응에 의해 디젤 및 �F싸로 전환하는 석탄간접액화기술은 현재 남아공 Sasol사에서 상업적으로 운전되고 있는 기술이나 국내로의 기술이전이 거의 불가능하다. 철을 기반으로 하는 고유 촉매와 scale-up이 가능한 반응기가 핵심인 기술로 국내에서 세미-파일럿급 액화공정 기술개발이 진행중이다. 전세계적으로 석탄액화공장의 수요가 현재의 15만배럴/일에서 2030년 240만배럴/일로 증가한다고 예측된다. 따라서 200조원 이상의 플랜트 시장이 기대되며 국산 가스화, SNG 및 액화기술로 상당부분의 시장을 장악하고자 한다.

This article assesses the recent police reform strategy in England and Wales with the Police Reform and Social Responsibility Act 2011. Police and Crime Commissioners have a responsibility not just for the police force but also for reducing crime in their area of responsibility. This ensures that their remit runs much more widely than their predecessor body, the police authority. The article goes on to evaluate the nature and extent of crime by making immediate use of survey of local police commanders. The surveys showed that police commands were swamped with minor crime and anti-social offences. The arrival of Police and Crime Commissioners has meant that now police priorities can be more closely aligned to those of the public and where anti-social behaviour is now recognised as impacting on the lives of many residents more significantly than criminal activity. The article highlights the changes introduced by government following the Winsor Review to police pay, pensions and conditions of service. It reflects on the impact of this on both police morale and professional motivation. It suggests that current government policy is now haemorrhaging the police service as increasing numbers of experienced officers are leaving the police service which could ultimately undermine its long-term resilience as a strategic emergency service.

Zirconium is one of the most important material used as cladding of fuel rods in nuclear reactors because of its high dimensional stability, good corrosion resistance and especially low neutron-absorbing cross section. However, Hf free nuclear grade Zr sponge is commercially produced by only three countries including USA, France and Russia. So, Zr has been thoroughly managed as a national strategic material in Korea. Most of the zirconium is used for Korean nuclear industry as nuclear fuel cladding materials manufactured from Hf free Zr alloy raw material. Also, there are some other applications such as alloying element and detonator. In this review, zirconium production and recycling technologies have been reviewed and current industrial status was also analyzed. And recent achievements in innovative reduction technologies such as electrolytic reduction process and molten oxide electrolysis were also introduced.

Traditional screening techniques have missed up to 99% of microbial resources existing in the nature. Strategies of direct cloning of environmental DNAs comprising tine genetic blueprints of entire microbial metagenomes provide vastly more genetic information than is contained in the culturable. Therefore, one way to screening the useful gene in a variety of environments is the construction of metagenomic DNA library. In this study, the water samples were collected from Daecheong Reservoir in the mid Korea, and analyzed by T-RFLP to examine the diversity of the microbial communities. The crude DNAs were extracted by SDS-based freezing-thawing method and then further purified using an $UltraClean^{TM}kit$ (MoBio, USA). The metagenomic libraries were constructed with the DNAs partially digested with EcoRI, BamHI, and SacII in Escherichia coli DH10B using the pBACe3.6 vector. About 14.0 Mb of metagenomic libraries were obtained with average inserts 13 ${\sim}$ 15 kb in size. The genes responsible for degradation of 1, 2-dichloroethane (1, 2-DCE) via hydrolytic dehalogenation were identified from the metagenomic libraries by colony hybridization. The 1, 2-dichloroethane dehalogenase gene (dhlA) was cloned and its nucleotide sequence was analyzed. The activity of the 1, 2-DCE dehalogenase was highly expressed to the substrate. These results indicated that the dhlA gene identified from the metagenomes derived from Deacheong Reservoir might be useful to develop a potent strain for degradation of 1, 2-DCE.

Effective and alternative strategies to control methicillin-resistant Staphylococcus aureus (MRSA) are consistently needed. Previous study presented that 7,10-epoxy-octadeca-7,9-dienoic acid (EODA) was produced from 7,10-dihydroxy-8(E)-octadecenoic acid through one-step heat treatment. Further studies confirmed that EODA was highly active against broad range of pathogenic bacteria including MRSA, promising development of a novel antibacterial agent to control MRSA. However, there are some practical huddles for industrialization of EODA, especially high cost for fine purification. To address this problem, this study was focused on determination of any changes in the antibacterial activities of EODA when used as a crude extract. As a result, any significant changes in the antibacterial activities of EODA was not detected and additional synergistic effect for commercial antibiotics on antibacterial activity was sustained as it was.

This study critically reviewed whether the South Korean press reported the issue of conflict between South Korea and Japan in a way consistent with their journalistic values. To this end, this study conducted frame analysis and textual analysis for the articles of three press(Chosun Ilbo, Hankyoreh and KBS) from the three major branches of conflict (Korea's Supreme Court's ruling on forced labor compensation in October 2018, the Japanese government's decision to regulate exports in July 2019 and the Korean government's decision to end GSOMIA in August 2019) to one week. There were many superficial reports of simply relaying conflicts around the occurrence and outcome of events, and there were few reports that analyzed the context in depth or suggested alternatives. And partisan reporting, which is cited as a key issue in the Korean journalism, has been strongly revealed in the midst of a conflict between Korea and Japan, a national emergency situation.

Recently, the importance of self-directed learning has emerged in the fields of public education, private education, lifelong education, and vocational training education, in which learners can actively cope with knowledge in an infusion-oriented way. However, there are various theoretical knowledge such as concepts and strategies for self-directed learning, but the situation is insufficient for a system where learners can easily receive content in the academic field they want, depending on the actual self-directed learning operation plan or learning area. Therefore, since it is important to provide various learning content in this paper, we utilize text mining techniques to obtain appropriate information and refine and categorize the meaning. On-line, they want to study a system that provides a variety of content in the academic field that learners are trying to acquire.

Public order management is one of the most important areas in policing. Drawing on the legal framework and policy, this study aims to assess practices of criminal justice practitioners, especially, police and prosecutors, in England and Wales. Using qualitative interviewing, four main themes are identified: (1) an emphasis on a right to protest, (2) police practices on public order management, (3) the development of police/prosecutor liaison, and (4) the value of video evidence. Based upon these findings, several legal, policy and practice implications are drawn. These implications involve a wide range of aspects concerning strategic, operational, and tactical interventions by the police, as well as collaboration between police and prosecutors. Although the criminal justice context in England and Wales is very different to South Korea, some practices and distinctions can be useful to consider in the Korean context. This study suggests that more gains can be made if legislation, policy, and practice across criminal justice nodes can be coordinated and approached holistically.
