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.

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.

This clinical case reports the effect of Chilgi-tang, a kind of traditional Korean herbal medicine, on $3^{rd}$ degree AV block patients also known as complete heart block. Complete heart block caused by degeneration of electrical conduction system of heart may result in weakness, dizziness, syncope, etc. Two clinical cases reported herein are diagnosed as $3^{rd}$ degree AV block caused by psychological stress with chief complaints of syncope and dyspnea respectively. The chief complains of cases cured remarkably after Chilgi-tang medication. In one case, $3^{rd}$ degree AV block was disappeared. In conclusion, we suggest that Chilgi-tang can be a potential treatment for complete heart block due to psychological stress.

(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.

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.

췌장에서 분비하는 인슐린과 글루카곤의 자극-분비 coupling 과정은 주로 혈당 농도와 중추신경계에 의하여 조절되어진다. 본 연구는 頭部에 포도당이 결핍되었을 때에 중추신경계가 췌장에서 인슐린과 글루카곤이 분비되는 패턴을 Sprague-Dawley 흰쥐를 대상으로 하여 살펴보았으며, 실험 방법은 in situ 뇌-췌장 관류법을 이용하였다. 관류액은 100 ㎎/dL glucose와 20 mM arginine를 포함한 Krebs-Ringer 완충액 (pH 7.4)으로 하였으며, 95% O₂-5% CO₂ 가스를 계속적으로 주입시키면서 5 ㎖/min의 속도로 30분간 정주하였다. 대조군은 cephalic glucopenia가 일어나지 않는 군으로 하였고, 실험군은 두 군으로 나누어서 GLP1군은 cephalic glucopenia가 0분에 일어나도록 하였고, GLP2군은 16분에 일어나도록 하였다. 문맥으로 유출되는 췌장의 effluent액에서 인슐린과 글루카곤 농도를 RIA법으로 측정하였고 호르몬의 분비 속도를 산출하여 분비동태 양상을 분석하였다. 결과에서 인슐린 분비량은 GLP1군에서 가장 낮아서 cephalic glucopenia에 의하여 다소 감소하는 경향이었으나, 세 군간에 통계적으로 유의적인 차이는 없었다. 인슐린의 분비동태 양상을 살펴보면 이봉성의 정규 양상을 보였으나, GLP1군에서 첫 번째 peak (4 min)가 다소 둔화되는 현상을 보였다. 글루카곤의 분비동태 양상도 이봉성의 정규 양상을 보였으며, 특히 GLP1군에 있어서 0~15분간의 글루카곤 분비량은 cephalic glucopenia에 의하여 유의성 있게 (p<0.05) 증가하였다. GLP2군에 있어서 글루카곤 분비량은 관류 후 15~30분 사이에 증가하는 경향을 볼 수 있었으나 통계적인 유의성은 없었다. 따라서 頭部의 포도당 결핍은 글루카곤의 분비를 증가시키는 것으로 나타났고, 이러한 현상은 특히 관류의 early period에서 현저하였다. In situ brain-pancreas perfusion was performed on male adult Sprague-Dawley rats, of which the central nervous systems (CNS) were intact during the perfusion procedure. The modified Krebs-Ringer buffer with 100 ㎎/dL of glucose and 20 mM of arginine was perfused for 30 min. In the experimental groups, a cephalic glucopenia was induced at 0 min (GLP1 group) or at 16 min (GLP2 group). The glucopenia was not induced in the control (CONT group). Insulin and glucagon concentrations in the effluent samples from the pancreas were measured using a RIA method. In all three groups, the first and second phases in the dynamics of the insulin and glucagon secretion were observed, which was a typical biphasic secretory pattern. The amount of insulin secretion tended to decrease in the GLP1 and GLP2 groups, but there was no statistically significant difference among the groups. However, the amount of glucagon secretion during 0~15 min of the perfusion period in the GLP1 group was greater as compared to the CONT group (p<0.05). The amount of glucagon secretion during 16~30 min of the perfusion period in the GLP2 group tended to be greater as compared to the CONT group, however there was no statistical significance. These data indicate that the cephalic glucopenia stimulates the direct secretion of glucagon from the pancreas during the early period of perfusion in the CNS-intact pancreatic perfused rats.

The purpose of this study is to examine aesthetic sense of dance in Western and Korean art works. The method of approaching dance and art works was based on essential attribute of dance and art history. Theoretical background was easily founded in publications and research papers. To examine Western and Korean art works, Edouard Manet, Edgar De, and Henri Matisse were selected for Western-style painters, and Hongdo Kim, Yunbok Shin, and Eunho Kim were selected for Korean-style painters to discuss their life and masterpieces. To discuss aesthetic sense of their masterpieces, the characteristics of Western and Korean art works were examined. The following findings were given: First, the characteristic of Western art works was that the distance between person and nature, or object and object was perfectly proportional by using perspective. Realistic description, free-form expression, and beauty of movements were also founded. The color sensation of Eastern art works emphasized on harmony of nature and human, however, Western art works focused on rationalism. The harmony of color, light, and drawing style were subjective expression by severance of nature, not the affirmative or active view of the objects. Second, the characteristics of Korean art works was that landscapes or objects was mostly placed in front rather than the back. Also, Korean art works had very detailed expression. However, the Western perspective seted a limit on seeing only one viewpoint. Because of the Western perspective, it is possible that the object at the back cannot see in the front, and only one viewpoint existed to draw actual feature. The color sensation of Korean art works reflected the Korean emotion, culture, and thoughts as well as construction, furnitures, handicrafts, and foods. This fact showed that Korean cultures autonomously shared its features in every categories. In the result, if Western art works were focused on human as the center with nature, Korean art works were focused on harmonizing of human and nature. This feature related with human, and there were many common features between Western and Korean art works. Through the result, followings were proposal: First, this study was limited on Western and Korean art works. Therefore, a follow-up study is needed to examine as aesthetic sense of dance in Korean art works. Second, dance in Korean art works should be selected of the times and examine the change of dance image. Therefore, a follow-up study is needed to examine the change of dance image by the phases of the times.

현대 영화에 나타난 시간성의 표현 방식

최현주(Choi, Hyun Ju) 청운대학교 방송예술연구소 2016 미디어와 공연예술연구 Vol.11 No.1

이연구는 최근 등장한 영화들 가운데 시간적 구조를 영화 형식에 가장 흥미롭게 표현한 <500일의 썸머>와<그랜드 부다페스트 호텔>을 연구 대상으로 선정하여, 이들의 시간 구조가 어떻게 구성되어 있으며 이러한 구성이 어떻게 시각화되었는지 살펴보았다. 이를 통해 ‘표현의 형식’으로서 이야기의 구성이 스토리를 전달하는 도구일 뿐만 아니라 시각적인 ‘표현의 도구’로써 어떻게 사용되어졌으며, 그러한 이야기의 표현 형식이 스토리텔링에서 어떠한 의미를 지니는 것인지에 대하여 고찰하였다. <500일의 썸머>에서 애니메이션으로 구성된 인터타이틀을 통해 시간의 흐름에 대한 정보를 제공하고 각 날짜별로 남자주인공의 심리상태나 연애상황을 인터타이틀의 영상에 표현함으로써 기억이 갖는 임의적인 시간의 배치로 인한 이야기 구성의 비논리성을 보완하는 기능을 하고 있다. <그랜드 부다페스트 호텔>은 다양한 시기의 이야기를 액자식으로 구성하고 있는데, 각 시기의 이야기가 진행될 때 그 당시 사용했던 화면 비율을 사용함으로써 한 편의 영화 내에서 화면의 크기가 각기 달라진다. 즉, 액자식 구성으로 이야기가 진행됨에 따라 1980년대(1.85:1), 1960년대(2.35:1), 1930년대(1.37:1)의 각 시기별로 그 당시 사용했던 화면 비율을 사용함으로써 각 시대의 분위기와 예술적인 감각 등을 재현하였을 뿐만 아니라, 시간의 배열을 독창적으로 시각화하였다. 이들 두 영화에서 시간의 배열을 시각화한 이러한 표현 방식은 현대 영화들에서 보여지는 상투적인 시간의 왜곡 구조에 창의적으로 접근하였다는 점에서 의미가 있다. 이들 영화의 경우 비연대기적 서사방식 그 자체가 새롭다고 할 수는 없지만, 이러한 서사방식을 시각적으로 표현하는 방식의 독창성이 관객에게 신선함과 퍼즐을 풀어내는것과 같은 쾌감을 준다. 이러한 시간성 표현들은 단지 영화가 말하고자 하는 내용을 전달하는 형식에 그치는 것이 아니라, 그 표현을 통해서 스토리텔링에서 또 다른 의미를 생산하는 역할을 하게 된다 The purpose of this study is to analyze the expression of time flow in modern cinema, and to discuss its aesthetic implications. In this study, I have analysed two recent films, which are discriminated from other films in terms of taking twisted time flow and visualizing it - <500 Days of Summer>(2010) and <Grand Budapest Hotel>(2014). As a result, it is found that the twisted time flow of the films put us to confuse the time arrangement. The films, however, visualize the information of time flow with inter-title animation in <500 Days of Summer>, and with the change of aspect ratio in <Grand Budapest Hotel>. The visualization of time flow, thus, compensates for non-logicality of the storyline.
