Objectives: Because recently hospital had to faced with financial hardship, we have to have more effective hospital management. The purpose of this study was to reduce loss costs of the hospital through the systematic management of medical supplies and increase operational efficiency. Methods: The team was composed of outpatient nursing staff, medical record administrator, nurses in medical insurance, medical computer center, dermatologists for this study. We surveyed for 114 people including outpatient nursing staff, nurse aids, medical assistant, physician assistant. Pre-survey period was 2013.03.11 ~ 03.30(2 weeks), and post-survey period was 2013.09.03 ~ 09.17(2 weeks). Result: We improved this way through the computational improvement, conservation campaigns, inventory management, staff training, replaced by low-cost medical supplies. The finding of this study were as follows: Comparing before and after the activity of outpatient nursing staff's degree of knowledge, performance, economic consciousness, the degree of knowledge, performance was increased, but there was no significant change in economic consciousness. Performance of Married person is higher than the unmarried, In addition, the high-position people were more the degree of knowleage, economic consciousness. After activity, correlation of goods and treatment, examinations is increasing, but statistically there was no mean. Conclusion: This study revealed that knowledge in a short period of activity, but also can improve, perform the same change in behavior is not easy. This one shows the intensive training required to sustained and systematic behavioral changes, such as changes in behavior, perform rituals to help the economy. Expensive medical supplies to replace a similar effect as the cost of materials just to have a lot of cost savings. Therefore, more medical supplies change is necessary to develop alternative treatment and cost cutting.

(110) 배향 TiO$_2$ 단결정 위에 성장시킨 CrO$_2$(110) 박막의 결정 구조, 미세구조와 자기적 특성의 상관 관계에 대해 연구하였다. 소스 물질로는 CrO$_3$ 분말을 사용하였으며, 열분해 화학증착법으로 CrO$_2$박막을 형성하였다. (110) 배향된 TiO$_2$루타일 단결정 위에 형성된 CrO$_2$ 박막은 (110) 방향으로 우선 배향되었고, 미세구조적으로 평활한 박막을 형성하였다. 흘려주는 산소량이 많을수록 CrO$_2$ 박막의 두께가 두꺼워지고 저항치가 낮았으며, 음의 자기저항치의 변화 및 자기 이력 곡선에서 보자력과 잔류 자화 값이 감소하는 경향을 보였다. We report the magnetic properties, microstructures, and crystal orientations of the CrO$_2$ thin films on TiO$_2$ single crystals. CrO$_2$ thin films were deposited by thermal decompositions with CrO$_3$ source materials. The microstructure of (110) oriented CrO$_2$ thin films deposited on (110) TiO$_2$ single crystals were uniform. As the oxygen flow rates increased, the resistivity, coercive field, and remnant magnetization of the CrO$_2$ thin films on TiO$_2$ single crystals decreased.

This paper proposes a mobile robot platform for education that can experiment with various autonomous driving algorithms such as obstacle avoidance and path planning. The platform consists of a robot module and a remote controller module, both of which are based on the Arduino Nano 33 IoT embedded board. The robot module is designed as a differential drive type using two encoder motors, and the speed of the motor is controlled using PID control. In the case of the remote controller module, a command to control the robot platform is received with a 2-axis joystick input, and an elliptical grid mapping technique is used to convert the joystick input into a linear and angular velocity command of the robot. WiFi and Zigbee are used for communication between the robot module and the remote controller module. The proposed robot platform was tested by measuring and comparing the linear velocity and angular velocity of the actual robot according to the linear velocity and angular velocity commands of the robot generated by the input of the joystick.

Even up to now, there are a lot of rhetoric words attached to the name of Seung-hee Choi (Nov. 24, 1911~Aug. 8, 1969), a Korean woman modern dancer. Her name is still re-titled with complimentary expressions such as ``Legend of Oriental Dance``, ``Dancing Girl of Korean Peninsula``, ``Flower of Joseon``, ``World-famous Dancer``, ``Legendary Woman Dancer`` and ``Immortal Woman of Myth.`` Choi developed her remarkable career of dancer across many international regions including Korea, Japan and Europe in the age of colonized Korea under the rule of Japanese imperialism. She lived her life with fetters of sorrow and pleasure till she went to North Korea with her husband. In the history of modern Korea, Choi is recognized as a rare figure of modern Korean woman who extended the boundary of her career into movie actress, singer and fashion model beyond dancer. A great number of conventional academic studies on Seung-hee Choi can be found in dancing and literature world, but most of those studies have focused primarily on artistic life, orientations, achievements and activities of Choi as well as her philosophical values. Based on the life story, artistic activities and critical biography of Choi, this study intends to take a new approach of art marketing to exploring her artistic achievements and values. The perfection of a performing art work is still valued so much as a means of creating audience value from its performance on stage, but the importance of multilateral promotions and novel planning is not to be overlooked. Whether Choi adopted such a planning and marketing means intentionally or unintentionally, her performing art activities demonstrate that she surely tried to promote herself by other means than perfection and value of a performing art work, and really wanted to get her performing art recognized by audience and make her dance known to more people. Thus, this study sought to take a new approach to the original artistry of Choi from the viewpoint of performing art planning and art marketing. Based on lots of existing academic literatures on Choi, this study attempted to define her identity as a s ort of brand and goods in the aspect of modern strategic planning, and took an approach of strategic planning to further examination into her artistic achievements, values and features on the basis of SWOT analysis.

The aim of this study is to investigate Dewey's theory of schools in his works and to examine critically its effects based on the situation of our schools. Conclusions are followings: Firstly, we confirmed that Dewey's theory of school constructed by sharp observation and deliberate insight about undesirable situations of elementary schools and secondary schools. Dewey criticized continuously unreality, incompetence and inadaptability of schools in those days. Furthermore, he tried to reform elementary schools and secondary schools for reconstruct new society. Experimental school in Chicago was one step to reform American schools confronted with changing situations. Secondly, we found that Dewey suggested some important needs and directions of school reform based on the systematic examination about problems of school. Dewey attempted to change traditional conception of school. Thus Dewey insisted that schools have to grow the life experiences, to play as center of social reform, and to learn democratic procedures. Thirdly, we examined the undesirable situations and roles of our schools governed by traditional methods based by Dewey's theory of school. Although problems of our school is not same to its problems in Dewey's day, conceptions and suggestions about school of Dewey will usually throw hopeful light to our school society to want essential reform and progressive change in immediate future.

지역방송 프로그램의 전국 네트워크 의무 편성에 관한 시론적 연구

최현주 ( Hyun Ju Choi ) 한국지역언론학연합회 2010 언론과학연구 Vol.10 No.1

본 연구는 지역방송이 태생적으로 지니고 있는 광고시장의 협소함이라는 구조적인 한계점을 극복하고 지역방송 경영 안정에 가장 크게 기여할 수 있는 방안은 부수적인 유통 창구의 개발에 선행하여 지역 프로그램이 규모의 경제를 실현할 수 있도록 지역방송 프로그램의 전국적인 배급체계 구축이라는 인식에서 출발하였다. 따라서 지역 프로그램의 전국 네트워크 의무 편성에 초점을 맞추어 지역방송 프로그램의 전국 방송체계 확립에 대한 기존 논의들을 검토하고, 지역 프로그램의 전국 네트워크 의무 편성을 위한 구체적인 실현방안은 무엇인지, 그리고 실행 시 검토해야할 과제가 무엇인지에 대하여 고찰하였다. 지역 프로그램의 전국적인 유통 방안 중에서 지역방송사의 경영 안정에 가장 효과적으로 작용할 수 있는 방안은 바로 지역방송사가 제작한 프로그램이 주시청시간대(Prime Time)에 전국 네트워크를 통해 정규적으로 방송될 수 있도록 하는 의무화정책이라 하겠다. 주시청시간대(7PM~11PM) 4시간 가운데 1시간 이상은 지역방송사가 제작한 프로그램을 전국 방송할 것을 의무화하는 제도를 마련하는 것이다. 이 규제는 프로그램의 전국 방송을 통한 규모의 경제를 실현하여, 최소 수준에서나마 지역방송사의 안정적 수입을 보장함으로써, 지역방송사들로 하여금 시장에서의 퇴출 위험성을 줄여줄 수 있을 것으로 나타났다. 뿐만 아니라 계열사들의 광역화를 실현함으로써 방송사의 구조개편에도 기여할 수 있음을 알 수 있었다. This study is to examine the prime time local access rule(PTLAR) which aims to distribute nationally local broadcasting programs. Currently the local television stations suffer from financial problem due to the narrow advertising market induced by a unstable local economy. The study reviews the literature dealing with how to revitalize local television stations financially by focusing on the change in distribution policy of the local programs. It suggests that PTLAR is a effective way of stabilizing the revenues of local broadcasting station by distributing the local programs nationally. PTLAR sets the obligation for the national network televisions to broadcast local programs during prime time. Specifically, this study suggests that the national network televisions should broadcast the local programs at least for an hour during the prime time from 7 pm to 11 pm. The rule would establish a stable advertising revenues of local stations by economies of scale. Otherwise the local stations would be out of market, which is a big threat to a local democracy. The study also suggests that the local televisions should restructure to enlarge their audience market through the integration of the stations.

미소기둥압축시험법을 이용한 감광성 폴리머의 기계적 물성 측정에 관한 연구

최현주 ( Hyun Ju Choi ),김용성 ( Young Seong Kim ) 경남대학교 신소재연구소 2013 신소재연구 Vol.25 No.-

본 연구에서는 나노압입시험기를 이용하여 나노-마이크로 구조물 및 소자들의 공정에 널리 이용되는 감광성 폴리머인 SU-8의 기계적 물성 값을 측정하였다. 이는 소자들의 설계시 반드시 필요한 값이며, 정확한 기계적 물성 값은 소자의 신뢰성 및 제품의 성능과 매우 밀접한 관련이 있다. 폴리머의 기계적 물성 값을 구하기 위하여 MEMS 공정을 이용하여 직경 7.5∼20 ㎛의 미소기둥 시편을 제작 하였으며, 일축 압축 실험을 통해 응력-변형률 곡선을 구할 수 있었다. 이를 통해 3.53 ± 0.12 GPa 탄성계수와 118 MPa의 항복강도를 구하였다. 또한 시편 사이즈 조건과 다양한 변형률 속도에 따른 기계적 특성을 고찰하였다. In this study, we used an advanced Pillar Compression Test using nanoindentation apparatus to measure the stress-strain relationship of SU-8 micro pillars fabricated by MEMS process. The stress-strain relation and mechanical properties of SU-8 pillar are extracted from the measured load-displacement data. To measure their mechanical properties, uniaxial compression test is performed using nanoindentation apparatus with flat-ended diamond tip. In addition, the dependency of compression properties on loading condition and specimen size are discussed.

디지털 테크놀로지의 발달과 다큐멘터리 스토리텔링 방식의 변화

최현주 ( Hyun Ju Choi ) 한국지역언론학회 2013 언론과학연구 Vol.13 No.2

2000년대 이후 디지털 테크놀로지의 발달과 다매체·다채널로 대변되는 매체환경의 변화 속에서 다큐멘터리의 장르적인 관습의 한계를 넘어서는, 시청자들의 관심과 호응을 이끌어내는 새로운 형태의 다큐멘터리들이 등장하고 있다. 캠코더의 소형화, 경량화에 의해 기동성과 현장성을 확보하게 되면서, 일상적인 소재를 재발견하여 구성한 프로그램들이 등장하기도 하였다. 또한 첨단 촬영기술의 발달로 이전까지는 촬영이 불가능하였던 영역을 영상화할 수 있게 되면서 다큐멘터리에서 다루는 소재의 영역이 확장되어 인체내부나 인간의 인지과정 및 심리를 다루는 인간의 심리 과학 다큐멘터리 등 새로운 장르의 다큐멘터리가 등장하기도 하였다. 뿐만 아니라 컴퓨터 그래픽 기술의 발전으로 상상의 영역이었던 부분들도 시각화할 수 있게 되면서 <한반도의 공룡>과 같은 자연사 다큐멘터리도 등장하게 되었다. 이렇듯 디지털 테크놀로지의 발달과 더불어 다큐멘터리의 외연은 무한히 확장되고 있는 것으로 보인다. 하지만 디지털 테크놀로지의 발달이 다큐멘터리 스토리텔링의 영역에도 새로운 변화를 가져오고 있는가에 대해서는 면밀한 고찰이 필요하다. 즉, 디지털 테크놀로지의 발달로 다큐멘터리가 외연적으로 확장될 뿐만 아니라 내적으로도 변화, 성장, 발전되고 있는지 살펴보았다. 이러한 고찰을 통해 디지털 테크놀로지가 다큐멘터리 장르에 가져다 준 변화의 함의를 논하였다. The purpose of this study is to investigate the change in the mode of documentary storytelling according to the development of digital technology. The development of digital technology such as a compact and light digital camcorder, non-linear editing system, and computerized special effect programs makes a new documentary appear. The items that documentary can deal with have been expanded due to the digital technology. The documentary dealing with the inside of the human body or human psychology has appeared. The documentary dealing with the ancient natural history has also appeared. To find out some considerable changes in documentary storytelling after the digital technology has introduced, 11 documentaries were examined. The results are as follows: The expression domain of documentary has been changed a lot. The way of structuring a story, however, has little been changed. It shows a lack of effort in seeking novelty in the way of constructing a story, as only devoting to expansion of the capabilities of visual expression. Thus, it is needed to try more diverse storytelling approaches in documentary.
