최연이,조인휘 한국화재소방학회 2008 한국화재소방학회논문지 Vol.22 No.3

최근 대규모 및 초고층 복합 건물 화재에서 실시간 현장상황 파악 및 신속한 인명 구조와 구조대원의 안전한 생명 보장을 위하여 유비쿼터스 기반 첨단 방재시스템의 필요성이 증대되었다. 본 논문에서 초고층 건물 화재의 특성과 위험성을 분석하고 단순성과 확장성을 제공하는 효율적인 메쉬 라우팅을 이용한 피난유도 알고리즘을 제안하였다. 우리의 연구는 센서네트워크를 구축하여 초고층 건물의 화재 및 재난 발생시 실시간으로 화재 및 생존자 위치정보와 화재상황 정보를 감지하고 유도등과 연계한 메쉬 라우팅 알고리즘 기법을 이용하여 신속하고 안전한 피난경로를 제시한다. When big fire in high rise building and multiplex happens, the needs for high prevention system of disaster are being increased for getting the real-time scene state, quick lifesaver, and safe life security. In this paper the proposed evacuation guidance algorithm which analyzed the feature and danger of fire in high rise buildings, gave simplicity and scalability. Our research shows as fire and disaster occur in high rise buildings we construct sensor networks and sense realtime location information on fire alive people, and the situation information for fire instructed quick and safe escaping route by using mesh routing algorithm scheme relative to exit sign.

An experimental study on the ignition and emissions characteristics of wallpapers

최연이,조인휘,이성은,오규형 대한기계학회 2009 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.23 No.10

The combustion characteristics of wallpaper and the toxicity of gas produced from wallpaper fires were analyzed to evaluate the fire risk of wallpaper used in living spaces. Ash content was measured with a high-temperature electric furnace, and thermal analysis was carried out with thermogravimetric analysis (TGA). Combustion time and smoke concentration were measured with a cone heater and a combustion gas analyzer. The smoke density of samples was measured using the smoke chamber ASTM E 662. Pyrolysis in silk wallpaper began at a lower temperature than the other samples. This means that silk wallpaper can be ignited at a low heat flux and will have a greater fire risk than other kinds of wallpaper. Heat by radiation flux caused silk wallpaper to ignite in the shortest time compared to the other samples, so the time for evacuation in this situation may also be reduced. Silk wallpaper also released the highest carbon monoxide concentration, so the toxicity and harmful effects to consciousness were stronger than any other wallpaper. The smoke densities of silk wallpaper and fire retardant-treated silk wallpaper were very high due to their vinyl coatings.

金子みすゞ詩における〈港〉のトポス ―「漁夫の子の唄」を中心に―

崔蓮?(Choi, Yeon-Hee) 대한일어일문학회 2021 일어일문학 Vol.89 No.-

Kaneko Musuzu, a Japanese children’s poet, wrote many poems about harbour. A ‘harbour’ or ‘port town’ is where she lives, where she wants to escape, and a place she longs for. This article investigates her poetry and their topics in terms of the evocation of a ‘harbour’ for various rhetorical purposes. A ‘harbour’ is a crucial place, which means a lot for her poetry, and characterizes her work. Her poem begins with the desire to leave the ‘port town.’ She gazes onto the sea and imagines an island far away from her town. She invites herself into the imagination, in which she stands at the ‘harbour’ and then transfers her body freely from one place to another Kaneko can only follow ships and sails, which call in at the port and then sail into the sea. For her, the ‘port town’ is a lonely and harsh place to live in. At the ‘harbour,’ she longs for a place far removed from the sea. When Kaneko’s longing for a far-flung places grows stronger, her lyrical expressions of moving to another place far beyond the sea emerge. Kaneko has such a strong desire to leave the ‘port town,’ in particular Shimonoseki, where she settled after her marriage. Her life at Shimonoseki drives her to despair. She yearns for an island. However, she feels loneliness on the island, once she imagined reaching there. She looks for a way for contacting people in the ‘port town,’ which is her hometown, Senzaki, and hopes to mingle with them. In this context, the port of Senzaki becomes a nostalgic place for her, although her life at her hometown, in fact, had been tough. Kaneko turns her gaze the other way around and looks at the ‘harbour’ from an islander’s viewpoint. Her argument of topos, which started at a ‘harbour’ or ‘port town,’ projects out an island, and again shifts back to a ‘harbour. She seems to have thought about the feelings of islanders. Kaneko evokes the image of herself living happily there, although she feels like an outsider. When describing a Korean child’s life, who crossed the sea and moved to Japan in the recent past, she overlaps her own image living on an island with that of the child. Kaneko hopes him/her to be happy in Japan, although he/she suffers from poverty. Kaneko, who has been unable to escape from the ‘port towns’ throughout her life, expands her yearning for an island. Her longing, which starts at her topos, a ‘harbour,’ is projected to various places in the eyes of her neighbours. This way, she evokes a ‘harbour’ for different rhetorical purposes

자기희생적 리더십이 구성원의 조직성과에 미치는 영향: 직장영성에 의한 매개효과

최연 한국자료분석학회 2014 Journal of the Korean Data Analysis Society Vol.16 No.3

Will the effects of self-sacrificial leadership on member’s organizational outcomes be mediated by the member’s workplace spirituality? This study is to empirically investigate the question. Using the research model in which leader’s self-sacrifice is the independent variable, member’s affective commitment and job satisfaction are the dependent variables, and member’s workplace spirituality (as measured by spiritual motivation) is the mediating variable, field survey data were collected from 255 participants. Data analyses results show a complete mediation effect of the member’s workplace spirituality (as measured by spiritual motivation) over the impact self-sacrificial leadership has on the member’s organizational performance (as measured by affective commitment and job satisfaction). This result is a stronger effect than the one reported in the previous research conducted by Choi (2011), where the mediating effect was partial. The need to refine the concept of spiritual motivation and future research issues are then discussed and proposed. 이 연구는 자기희생적 리더십이 구성원의 조직성과에 미치는 영향이 직장영성(workplace spirituality)에 의해 매개되는가를 검증하기 위한 것이다. 실증연구에서, 종속변수인 구성원의 조직성과는 구성원의 정서적 조직몰입과 직무만족으로, 매개변수인 구성원의 직장영성은 구성원의 영적동기부여로 측정되었다. 255명의 연구 참가자로부터 수집된 현장 서베이 데이터를 분석한 결과, 자기희생적 리더십이 구성원의 조직성과에 대하여 가지는 효과가 구성원의 직장영성에 의해 완전매개된다는 것이 밝혀졌다. 이는 선행연구(Choi, 2011)가 보고한 부분매개 효과보다 강력한 결과이며, 실험방법으로 수행된 선행연구의 취약점이었던 외적타당성 부족을 보완해 주고 있다. 매개변수인 직장영성의 측정에 사용된 영적동기부여와 관련하여, 개념적 정교화와 측정항목의 추가적 개발의 필요성에 대한 토의 및 연구의 시사점이 제시되었다.
