In this paper, Hwang Soon-won's "Sonagi" is considered from the aspect of literary imagination reconstructed into a fusion content of various cultures such as HD TV Literature, Animation, Movie, Musical, CF and the part which changed from the original text. In the TV literature Museum "Sonagi" he created a newly person called a 'Seok-yi' who is a young brother of a boy, a girl's mother who did not exist in the original, and developed the composition more precisely. And In the animation, the main character's dialogue is presented as a speech and it is characteristic that the theme of the work is revealed more effectively. On the other hand, the heroine in the movie says, "I do not like the ending part of the showers." Also In the musical "Sonagi", about 2 tons of water was used to give more vividness and presence to the audience. In this way, the contents of the original works are transformed according to the characteristics of the medium in the various cultural fusion contents based on novels, and thus convey the unique imagination of the director to the audience.

가스센서는 사내 및 산업 환경에서의 유독성 또는 폭발성 가스 검출, 환경 모니터링, 질병 진단 등 매우 다양한 응용분야에서 큰 관심을 가지고 있다. 반도체 금속산화물(SMOs) 기반의 센서 분야에서는 이들의 감도 및 선택성을 향상시키기 위해 많은 노력을 기울이고 있다. 이는 센서의 선택성을 부여하게 되면 다양한 가스들이 존재하는 환경에서도 검출자가 원하는 가스만의 응답을 얻을 수 있기 때문이다. 본 연구에서는 MOF(Metal-Organic Framwork) 기반 멤브레인으로 ZIF-8(Zeolitic Imidazolate Frameworks 구조들 중 하나) 멤브레인 쉘 층을 이용하여 ZnO 나노선에 형성하였다. ZnO 나노선은 VLS공정 (Vapor-Liquid-Solid)을 이용하여 패턴된 전극을 갖는 $SiO_2$-grown Si 웨이퍼 상에 성장되었고, 성장된 ZnO 나노선은 2-methyl imidazole과 methanol이 포함된 고용체에 넣고 폐쇄된 압력용기 속에서 가열시켜 얻게 된다. 이렇게 얻어진 ZIF-8@ZnO 나노선의 ZIF-8 멤브레인은 분자 체 구조(molecular sieving structure)를 갖게 되며, 이들의 pore 크기는 약 $3.4{\AA}$을 갖는다. 따라서 이보다 더 큰 동적 직경을(kinetic diameter) 갖는 가스 종은 이 멤브레인을 통과할 수 없음을 나타내므로 제작된 시편은 $H_2$(kinetic diameter : $2.89{\AA}$), $C_7H_8$(kinetic diameter : $5.92{\AA}$), 그리고 $C_6H_6$(kinetic diameter : $5.27{\AA}$) 가스들을 각각 사용함으로써 ZIF-8@ZnO 나노선의 센서 특성을 조사했으며, 보다 정확한 비교를 위해 순수한 ZnO 나노선 역시 동일한 조건에서 측정되었다. 결과를 통해, 수소 가스를 제외한 다른 가스들에 대해서는 반응을 하지 않고, 오직 수소 가스에 대해서만 반응을 나타냈으며, 순수 ZnO 나노선의 수소 감응도보다 낮은 감응도를 나타내었다. 이는 멤브레인 쉘 층을 형성함으로써 ZnO 나노선의 표면적이 감소해 가스 분자와의 접촉점을 감소시키기 때문이라고 판단된다. 이와 같은 MOF 멤브레인의 캡슐화 전략은 가스센서뿐 아니라 바이오 센서 및 광촉매 등과 같은 이온 선택성을 필요로 하는 다양한 응용분야에 적용될 수 있을 것으로 기대된다.

During the monitoring of fungal pests in 2016 and 2017, Acrodontium crateriforme, Naganishia friedmannii, Pestalotiopsis trachicarpicola, Penicillium wollemiicola, and Trichoderma thailandicum were isolated from indoor air, mushroom flies (Phytosciara flavipes), and media materials in the cultivation houses of oak wood mushroom (Lentinula edodes) located in Seocheon, Jangheung, Buyeo, and Yeoju, Korea. These fungal species were identified based on their morphological characteristics after their growth on PDA and subsequent molecular analyses of the 26S rDNA, 28S rDNA, β-tubulin gene, and translation elongation factor 1-α gene using PCR amplification and nucleotide sequencing were performed. The results showed that these fungi were previously undocumented in Korea. This study reports descriptions of their taxonomical and known properties.

Objectives: The purpose of this study is to review the debate on the Article 28(Prohibition of Inhouse-Contract for Harmful Work) of the Industrial Safety and Health Law. Methods: Literatures and recent debate for prohibition and permission of inhouse-contract for harmful work were reviewed. Proposals of revision for the Article 28 of the Industrial Safety and Health Law were also reviewed. Results: It was not found reasonable to revise the Article 28 based on increased fatal accidents or diseases in the electroplating work and heavy metals handling works that are currently listed in the Presidential Decree under the law as the harmful works. Regulation types of prohibition or authorization for any harmful work shall have inherently poor coverage since the scope of application is extremely limited. Contractors for maintenance and repair of chemical facilities may not be included in the scope of application if the harmful works are defined as chemical handling works. If harmful works are prohibited, the contractor workers may loose their jobs. Therefore, it is necessary to consider balancing job security and occupational safety and health safety. Conclusions: Various limitations were found in the Article 28 and the proposals to revise it. Currently in-house subcontracting is widely spread in the workplace. Therefore, it may be inappropriate to set one or two Article such as the Article 28 and 29 to protect in-house subcontract workers from injury and illness. It is believed that it needs fundamental redirection and new approach with new paradigm to impose occupational safety and health duty to prime contractors.

기업 네트워크에서 안전하고 효과적이며 안정된 망 운영관리 환경 제공은 당면한 중요과제이며 기업 경쟁력의 핵심인 정보기술을 통한 생산성과도 연계성을 갖고 있다. 특히 전력통신망의 경우 전자메일, 회계관리, 전자결재, 도면자료관리 등의 데이터 통신망에서부터 IBM 온라인, 사내 방송망, 전력계통설비 원방 제어용 시스템들 간을 연결하는 EMS, SCADA 등 전력 수급용 전용 통신망에 이르기까지 다양한 종류의 통신망이 구축 운용되고 있다. 이러한 기업환경에 따라 네트워크를 효율적으로 관리하기 위한 네트워크 관리 시스템에 대한 관심이 증대되고 있으며 많은 네트워크 관리 시스템들이 도입되어 운영되었으나 이들 관리 시스템들은 모니터링에 의한 통계값 제공과 같은 단순 평면적인 관리 기능만을 제공한 뿐 네트워크의 특성과 환경에 따른 분석, 진단 기능은 제공하지 못하고 있다. 이와 더불어 네트워크 관리자는 보다 손쉬운 방법으로 네트워크를 관리하고자 하며, 보다 지능적이고 효율적으로 관리하고자 한다. 하지만 관리 시스템이 모든 네트워크에 대해 효율적이고 지능적인 관리 기능을 제공하기는 매우 어려우며 이는 장기간의 관리 네트워크의 특성과 트래픽 형태를 파악한 후에나 가능하다. 결국 지능적이고 효율적인 네트워크 관리는 네트워크의 특성과 함께 이전에 관리자에 의해서 내려졌던 관리 행위 및 의견 그리고 조치에 대한 이력정보를 학습하고 있을 때만 가능하다. 본 논문은 전력통신망을 대상으로 전력통신망이 지닌 네트워크 특성을 반영하며 네트워크 운영 과정에서 축적된 관리자의 의견과 이에 대한 조치를 지식 데이터베이스화하여 지능적인 관리 시스템을 제공하기 위한 기반 시스템으로써 전력통신망 운용 관리 지원시스템을 설계 및 구현하였다. 본 시스템은 향후 지식 정보를 학습하고 이를 바탕으로 논리적인 추론을 통해 관리 네트워크를 지능적이고 자동적으로 관리할 수 있는 시스템으로 확대 개발될 것이다.
