Objective : The objective of this study was to survey the job-related empowerment and job satisfaction of 119 emergency medical technicians provide emergency patients with first aid, to examine the correlation between their empowerment and job satisfaction, and to provide basic materials for developing programs to enhance 119 emergency medical technicians' empowerment and job satisfaction. Methods : The survey was conducted with 249 119 emergency medical technicians working at fire stations in an area of Gyeonggi-do during the period from June 26 to August 21, 2009. Using SPSS 14.0 program, we obtained frequencies percentages, means, and standard deviations, and performed independent two sample t-test, one way ANOVA, and Pearson correlation analysis, and Cronbach's ${\alpha}$. Results : 1) The mean score of the subjects' empowerment was 3.32, and that of their job satisfaction was 2.94. 2) As to difference according to general characteristics, no statistically significant difference was observed in empowerment but job satisfaction was statistically significantly different according to gender(t = 2.296, p = .023). 3) As to difference according to job related characteristics, empowerment was significantly different according to license type(F = 3.767, p = .011), and job satisfaction was statistically significantly different according to position(t = 3.222, p = .042), fire fighting experience(t = 2.689, p = .035), and first aid experience(t = 3.991, p = .007). 4) Empowerment was in a positive correlation with job satisfaction(r = .502, p = .000) in general, and by the sub areas of job satisfaction, the correlation with empowerment was high in order of job itself(r = .695, p = .000), interaction area(r = .493, p = .000), organizational demand area(r = .328, p = .000), working condition area(r = .153, p = .015), and wage area(r = .137, p = .031). By the sub areas of empowerment, the correlation with job satisfaction was high in order of significance(r = .424, p = .000), influence(r = .397, p = .000), competence(r = .372, p = .000), and self determination(r = .259, p = .000). Conclusion : The 119 emergency medical technicians' empowerment was in a high correlation with their job satisfaction, and had a strong effect on it. This suggests that 119 emergency medical technicians' job performance can be enhanced by improving their empowerment. These results are expected to be useful in making human resource management plans to enhance 119 emergency medical technicians' job satisfaction by empowering them.

타 산업, 특히 제조업 분야의 경우 급격한 기술 및 인터넷 환경의 발전으로 인해 시장이 세분화되고 다품종 소량생산의 체제로 변화하였다. 이러한 사회적 변화는 주택 시장에도 변화를 가져와 공급자 중심에서 수요자 중심의 시장으로 변화하고 있으며 주택에 대한 소비자의 요구사항도 날로 다양해지고 있다 한편 주택의 장수명화를 실현하고 지속가능 한 건축 및 환경 구현을 위해 오픈 하우징 시스템에 관한 연구가 활발히 진행되고 있는 시점에서, 오픈 하우징 개념을 도입한 맞춤형 아파트의 도입이 증가하고 있는 추세이다. 그러나 아직 도입 초기 단계이기 때문에 맞춤형 아파트의 운영에 있어 많은 문제점이 드러나고 있다. 따라서 본 연구에서는 맞춤형 아파트 사업이 효율적으로 이루어질 수 있도록 하기 위하여 최근 입주가 완료된 맞춤형 아파트의 실무자들과의 인터뷰 및 운영 사례를 조사하여 문제점을 분석하고 그에 따른 개선방안을 제시하였다. Technical improvement and the growth of the Internet environment make the market segmental of the manufacturing industry. These social trends have had an effect on the housing market, and the housing market changed from the supplier-oriented to the consumer-oriented. In recent years the occupants' needs for the apartment is diversified and complicated. But the existing mass housing supply method has many problems. It couldn't satisfy the dwellers' various needs and couldn't reflect overall expected life span either. In order to realize the sustainable building & environment, the research for the open housing system is actively performed. Finally the custom-built apartment which imported the concept of the open housing is constructed. But after running the custom-built apartment, several problems are revealed. Therefore the purpose of this study is to analyze the problems and then suggest the improving methods for a custom-built apartment.

최근 하나의 휴대폰에 여러 가지 미디어들이 복합적으로 장착됨에 따라 휴대폰에서 제공되는 서비스의 사용자 보안에 대한 요구가 증가되고 있다. 현재 이를 위하여 비밀번호와 인증과정을 통한 암호화 카드를 이용하여 본인을 인증한 후에 서비스를 제공할 수 있는 암호화키를 생성하고 있지만 이는 분실의 위험에 언제든지 노출되어 있다. 따라서 상대적으로 분실의 위험이 거의 존재하지 않는 생체정보를 이용하여 키를 생성하는 연구가 많이 진행되고 있다. 하지만 생체정보는 언제나 동일한 키를 생성해내야 하는 암호화키 생성 시스템의 요구사항과 달리 환경의 변화에 따라 본인이라도 특징 추출시마다 약간씩 다른 특징값이 추출되는 문제점을 가지고 있다. 따라서 본 연구에서는 생체 특징으로부터 직접적으로 키를 생성해내는 생체 정보 기반 키 생성 방법(Biometric-based key generation)이 아닌 생체 정보 매칭 기반 키 생성 방법(Biometric matching-based key release)을 이용하여 미리 정의해 놓은 키를 인식과정을 통하여 도출하고 또한 하나의 생체가 갖는 성능의 불안정성을 극복하기 위하여 얼굴과 홍채를 결정 레벨(Decision Level) 에서 결합함으로써 모바일 환경의 특성을 반영하며 안정된 성능 하에 암호화키가 생성될 수 있도록 하였다. 또한 휴대폰에 내장되어 있는 메가 픽셀 카메라를 이용함으로써 한 번의 영상 취득으로 얼굴과 홍채 인식이 동시에 이루어지는 편리함을 제공하였다. 본 논문에서 제안하는 키 생성 방법의 성능을 측정한 결과, 암호화키 생성에 있어 0.5%의 EER(Equal Error Rate) 성능을 얻었으며, FRR(False Rejection Rate : 본인의 생체 정보로 타인의 암호화키가 나올 에러율)을 25%로 설정하였을 때, FAR(False Acceptance Rate : 타인의 생체 정보로 본인의 암호화키가 나올 에러율)은 약 0.002%의 성능을 얻었다. 동시에 본 시스템에서는 임계 치에 따라 암호화키 생성의 FAR과 FRR값을 동적으로 제어할 수 있는 기능을 제공하였다. Recently, as a number of media are fused into a phone, the requirement of security of service provided on a mobile phone is increasing. For this, conventional cryptographic key based on password and security card is used in the mobile phone, but it has the characteristics which is easy to be vulnerable and to be illegally stolen. To overcome such a problem, the researches to generate key based on biometrics have been done. However, it has also the problem that biometric information is susceptible to the variation of environment, whereas conventional cryptographic system should generate invariant cryptographic key at any time. So, we propose new method of producing cryptographic key based on "Biometric matching-based key release" instead of "Biometric-based key generation" by using both face and iris information in order to overcome the unstability of uni-modal biometrics. Also, by using mega-pixel camera embedded on mobile phone, we can provide users with convenience that both face and iris recognition is possible at the same time. Experimental results showed that we could obtain the EER(Equal Error Rate) performance of 0.5% when producing cryptographic key. And FAR was shown as about 0.002% in case of FRR of 25%. In addition, our system can provide the functionality of controlling FAR and FRR based on threshold.

인간형 재조합단백질 각질세포 성장인자를 안정적으로 생산하는 누에 배양 세포(Bm5-hKGF cell)을 만들었다, 이 세포에서 분비되어 배지에 포함된 양은 15-20 ng/㎖ 정도였다. Bm5-hKGF cell에 누에의 PDI를 함께 발현시키면 세포외 분비량이 2배 증가하였다. Wound healing migration assay 결과 누에세포에서 생산된 인간형 재조합단백질 각질세포 성장인자는 세포생장을 촉진하는 활성을 가지고 있었다. 본 실험의 결과는 누에배양세포를 사용하여 저비용으로 양질의 인간형 재조합단백질을 대량생산 할 수 있는 것을 기대한다. Using silkworm Bombyx mori Bm5 cells, we established a stable cell line expressing the human keratinocyte growth factor (hKGF), named by the Bm5-hKGF cell, in which the protein hKGF is synthesized in the cell and secreted in the cell culture supernatant (CCS) at approximately 15-20 ng/㎖. When the Bm5-hKGF cell was co-expressed with B. mori protein disulfide isomerase (bPDI) cDNA, its secretion increased by about two times the original amount. Through wound healing migration assay, it was demonstrated that the secreted hKGF included in the CCS has a very powerful biological activity of keratinocyte proliferation. We expect to produce useful human recombinant proteins from silkworm cultured cells in large quantities at low prices.

Three choline chloride (ChCl)-based deep eutectic solvents (DESs) with different hydrogen bond donors, i.e., urea, lactic acid, and glycerol, was used for the pretreatment of pussy willow to improve enzymatic saccharification. The amount of water soluble fraction, crystallinity index (CrI), and enzymatic saccharification yield of the pretreated product were investigated. The amount of water soluble fraction increased with increasing pretreatment time in all DESs. The amount of water soluble fraction was less than 20% in ChCl-based DESs with urea and glycerol, but ChCl-DES with lactic acid showed more than 50% of water soluble fraction even for short pretreatment time of 2 h. All pretreated products showed typical cellulose I crystalline structure, showing 57.6~72.9% of CrI. The yields of glucose and xylose were calculated in the basis of the original mass of raw material. Both yields were increased with increasing pretreatment time in ChCl-based DESs with urea and glycerol, whereas reverse in ChCl-based DES with lactic acid. The highest glucose yield of 42.3% was obtained from the pretreated products for the pretreatment time of 2 h.

Objectives The purpose of this study was to provide an in-depth understanding of art education in special schools for students with physical disabilities by describing the personal experiences of an art teacher in a special school for students with physical disabilities and to seek ways to cultivate professionalism in art classes. Methods The autoethnography research method was used as a means to the ends of this study. Autoethnography is one of the qualitative research methods that allows personal experiences to be interpreted in a socio-cultural context through the perspective of the first-person observer and the protagonist. Results First, I became aware of the individual characteristics of students with physical disabilities through introspection and self-reflection on art classes at a special school and feel keenly the necessity of developing cultural and material infrastructure. Second, I accumulated the practical knowledge of teachers through creative and self-directed art classes to seek breakthroughs for student-centered art classes. Third, have constantly tried to challenge myself on a path of self-reinforcement with the goal of becoming an art education expert in the field of special education. Conclusions As an artistht and an art teacher at a special school for students with physical disabilities, I learned that practical knowledge was accumulated through the practice of constructivist art classes led by learners in the art classes. Furthermore, these artistic experiences in art classes allowed students with disabilities to expand their creative thinking as well as their opportunities for a wide range of experiences.

이상적 혁명주의자의 헝가리 광시곡 -미클로스 얀초(Miklos Jancso)-

한송이 ( Song Yi Han ) 한양대학교 현대영화연구소 2009 현대영화연구 Vol.5 No.2

Michlos Jancso`s films dream of a revolution. This paper explores how he constantly claims to depict revolution through his films. With his firm perspective about film as an effective and powerful medium, he created his own `Jancso country`-a term given by a journalist to reflect his unique frame composition style clear themes. This research analyses his 7 feature films from <Igy jottem, My way home> (1965) that brought him to international prominence to <Magyar rapszodia, Hungarian Rhapsody> (1979) which is good evidence that he was still famous but remained true to his original forms and ideals. His films show us the Hungarian sense of community, which had dreamt of revolution in mise-en-scenes that is filled with members of the community he depicts and constant moving camera walks. Individuals or a community in his films inevitably fall, being subject to oppression and violence by Hungarian historical events. A revolution in his films is the one and only tool for emancipating the characters from oppression. It always ends tragically like the reality of previous Hungarian historical revolutions, but it is idealized using a religious dimension and successful use of ritual metaphors. Jancso had expressed his communist ideology in his films at first, but his themes were repeated after he had renounced communism. A revolution for him is a spirit that lives on whenever you need to free people from oppression. Whether it is the Hapsburg Empire, a landowner, an ultra right government, or a proletarian dictatorship.

본 연구는 기관 내 삽관 수행 시 성공률에 영향을 미치는 신체적 요인에 대해 알아보기 위한 비동등성 단일군 사후 유사 실험연구이다. 연구결과 기관 내 삽관을 성공적으로 수행한 시간과 신체적 요인은 상관관계가 있는 것으로 나타났다. 특히 기관 내 삽관 수행 시 수행자의 팔의 각도는 수행시간에 영향을 미쳤으며, 팔의 각도가 좁아질수록 수행시간이 짧아지는 결과를 보였다. 기관 내 삽관 수행 시 수행자의 팔의 각도를 줄일 수 있도록 노력한다면 성공적인 기관 내 삽관을 시행할 수 있을 것이다. 하지만 다양한 환경 및 직군에 대한 추가적인 후속 연구를 통해 임상적 활용의 가능성을 확인해야 할 것이다. In this paper, We propose the purpose the examine the physical factors that influence the success rate during the endotracheal intubation and to provide the basic data for effective intubation success. The subject of this study was 42 students in emergency rescue department who had completed the BLS Health Care-provider and a specialized airway maintenance course dealing with endotracheal intubation and it is a similar experimental study after the non-equivalence single group. For data analysis, SPSS 23.0 Version was used. The study methods were measuring the grip fotce of subjects, the angle of arm during intubation tube, distance from manikin, palm length, etc. The results showed that there was a correlation between the time of successful endotracheal intubation and the physical characteristics. In particular, when performing endotracheal intubation, it was related to the angle of the arm and the execution time of the performer, and the narrower the angle of the arm, the shorter the execution time. The results of this study suggest that successful endotracheal intubation could be implemented if the operator tried to reduce the angle of the arm when performing endotracheal intubation, and through further research on various job groups, identify the possibility of clinical use will be necessary.

특집논문 : 서유럽,독일, 프랑스 이탈리아, 스페인 현대 영화 감독론 ; 고립으로 소통을 말하다 -빅토르 에리세(Victor Erice)의 영화-

한송이 ( Song Yi Han ) 한양대학교 현대영화연구소 2010 현대영화연구 Vol.6 No.2

Victor Erice who is a film critic and directed two feature films that metaphorically represent Spanish young generation isolated from their parent generation under Franco`s dictatorship. This study focuses on his films <El espiritu de la colmena(The Spirit of Beehive)> and <El Sur(The South)> not as Spanish metaphorical films` tradition but their narrative and esthetical direction to maximize characters` isolation and rupture of relationship. Erice achieved his own realistic style as embodying isolated real world and dialogical fantastic world in the same film. In his style, he didn`t just intend to imitate the form of neo-realistic film style and baroque painting but develop it in the embodiment of character`s alienation. Also, this study explains how Erice framed fragmental characters` gazes and that the gazes meant rupture of main role characters` relationships and have to do with an narrative of isolation. His realistic style, fragmental gazes and narrative of isolation is maximized until the last end. That emphasizes the moments of humanistic dialogue and needs of communication in the film`s last scene strategically.

오메가-3 불포화지방산이 노인여성의 심혈관 반응 및 노르에피네프린에 미치는 효과

한송이(Song Yi Han),김경희(Kyung Hee Kim),조등(Cao Teng),김종경(Jong Kyung Kim) 한국발육발달학회 2013 한국발육발달학회지 Vol.21 No.4

It is generally known that Omega-3 polyunsaturated fatty acids (n-3 PUFAs) supplementations decrease risks of sudden death and cardiovascular diseases. A previous study showed that n-3 PUFAs supplements improved stroke volume and peripheral vasoconstriction in the young. On the other hand, in the elderly, systolic blood pressure increases because of arterial stiffness produced by structural alterations of arterial wall occurring with aging. However, the effect of n-3 PUFAs has not been revealed in older humans. Therefore, the purpose of this study was to investigate the effects of hemodynamic responses with n-3 PUFAs supplement at rest and during exercise in elderly women. Subjects (>60 yrs) were divided into only n-3 group (OG), n-3+Placebo group (CG), and placebo group (PG). All subjects completed submaximal exercise testing for 5-7 minutes (60% VO2peak) before and after the nutritional supplementation. Systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), stroke volume (SV) were continuously measured from rest through exercise. Blood samples were collected at rest and during exercise. There were no differences in HR and SBP at rest across groups. SBP was significantly decreased in OG (p<.05) and CG (p<.001) during exercise after the n-3 supplement. DBP and mean arterial pressure (MAP) were not significantly different at rest and during exercise across groups (p<.05). There were no differences in SV, cardiac output (CO), and total vascular conductance (TVC) at rest across groups. Both SV and CO were significantly decreased in PG (p<.05), and TVC were significantly decreased in PG (p<.05). Both SV and TVC tended to be increased during exercise in OG and CG. There was no difference in norepinephrine (NE) concentration at rest across groups, while NE tended to be decreased in OG and CG. These results suggest that n-3 PUFAs supplement could improve SV and blood flow to active skeletal muscle. Thus, n-3 PUFAs supplement may prevent hypertension and enhance exercise performance in elderly women.
