Purpose Recently, there has been increasing demands for clinical departments at Asan Medical center in Seoul. They want to see the results of lab tests about blood samples as soon as possible and to be reported to them on the day. As the main contents of the survey, we explained the goodness of Asan medical center's in vitro and the points to be improved. Based on this, it became an opportunity to create a positive image of In vitro laboratory. In addition, we could identify their specific requirements through the surveys. Materials and Methods In September 2016, a total of 14 questionnaire surveys were conducted for 49 clinical departments and outpatient nurses at Asan Medical center in Seoul. The survey consists of description questions to be able to express the intention of the individual and the questions made on the Likert 4 point scale. The main contents of 14 questions are composed of goodness of In Vitro laboratory and points to be improved. Results 62% answered that the best service in In Vitro laboratory was "good accuracy and reproducibility". On the other hand, as an inconvenience when requesting blood tests, 73% pointed out that "the result report time was long", which was recognized as a part to be improved. There are many contents that "The result of all tests is reported within 2 hours" on the day of the examination. In the question - 'Are there some examination results which do not coincide well with clinical observations?', 55 of 56 people answered "no". Above all, the majority answered that waiting for re-examination results is too long. This problem must be causing discomfort to the patients. Conclusion In order to improve these problems, the first thing is to increase the number of blood tests by using the current personnel, equipments and reagents to the fullest by item in Asan Medical Center's Nuclear medicine in vitro part. Secondly, in case of re-examinations, we use the "AMIS message" to show other clinical departments the reporting time. This methode improves the efficiency of work with nurses and increases satisfaction of custom service. Thirdly, the correlation was evaluated by selecting the test species that can be carried out by the shortening method. Currently, C-peptide and insulin are implemented in the reaction process to shorten 2 hours into 1 hour. Finally, we are considering purchasing new equipments for quick test results.

The purpose of this study is to investigate the mediating effect of learners" learning flow in the effect of presence on academic achievement in web-based e-learning. For this purpose, this study analyzed the influencing relationship between the each factor based on the structural model with the learning flow as a mediator variable. Based on existing theoretical studies, learning satisfaction and academic achievement, which represent learning outcomes, are set as dependent variables, and teaching presence, cognitive presence, and social presence are set as independent variables. Data collected from a total of 256 e-learning learners were used in the analysis of this study. According to the results of the analysis, teaching presence, cognitive presence, and social presence were found to have a significant effect on academic achievement when a learning flow is a mediator variable. Concretely, teaching presence, cognitive presence, and social presence have a positive effect on the learning flow, while learning flow has a positive effect on learning satisfaction. On the other hand, learning flow has a negative effect on academic achievement. As a result of verifying the mediating effect of learning flow on the relationship between presence, learning satisfaction, and academic achievement, there was meditating effect in the aggregate. This study implies that in order to increase the level of learning satisfaction and academic achievement, it is necessary to make the teaching-learning design in the provision of contents and materials for e-learning so that the learner can feel the presence. The results of this study can be used as a basic data for seeking support and promotion strategies for enhancement of future learning flow and presence.

본 연구에서는 IR과 CR의 블렌딩을 통하여 물성 개선 및 내구 성능 개선을 목적으로 IR/CR의 비율을 다양하게 블렌딩하여 제조한 고무시료의 가교 특성, 물성 변화, Morphology의 변화 및 화학적 특성을 조사하였다. 한편으로 블렌딩 된 고무에 다양한 조건으로 염소 표면처리를 하였을 때 고무시료의 Morphology를 관찰하고 마찰 시험을 통해 염소의 표면처리가 마찰계수에 미치는 영향을 조사하였다. 고무의 가교특성에서는 CR의 함량이 증가할수록 가교 속도가 감소하였으나 가교밀도는 일정하였고,경도, 모듈러스가 증가하였는데 이것은 가교특성의 변화와 밀접한 관계가 있으며, 가교 반응의 활성화에 의한 결정화 영향으로 기계적 강도가 증가하는 것으로 나타났다. 노화 후 물성 변화는 IR/CR Blend가 상호 기계적 물성의 단점을 보완하여 노화에 의한 물성 변화를 감소시키는 역할을 하는 것으로 나타났다. 염소 표면처리 한 시료의 노화 전, 후 상태물성의 변화는 감소하였다. 현미경 사진 관찰 결과 CR 함량 증가에 따라 표면 분산도가 증가함을 알 수 있었다. 염소 표면처리된 고무의 표면은 일정한 방향으로 균일하게 표면처리되었고 매끄러움과 광택이 증가하였다. 고무 표면의 개질 정도는 표면염소잔류량으로 확인할 수 있었으며, 마찰계수는 고무와 결합된 염소함량에 의존하는 것으로 나타났다. CR 함량이 10 - 40 phr까지는 표면처리 초기단계에서 마찰계수가 급격히 감소하였으나, 처리용액의 염소농도가 증가할수록 마찰계수의 감소는 둔화되었고, CR 함량이 50 phr에서는 처리용액의 염소농도 변화에 따라 마찰계수의 감소가 둔화되었다. In this study, rubber vulcanization property, change in physical property, morphology and chemical characteristics of blended rubber depending on various IR/CR ratio were investigated for the purpose of the improvement of material property and durability. The effect of surface treatment by chlorine on the friction coefficient was also studied with various conditions of surface treatment. In terms of vulcanization property, as the amount of CR content increased, the speed of cure was decreased, while the density of crosslinking stayed constant. It means hardness and modulus were increased as the CR content increased. It is related to change in cure property and mechanical strength was improved by the effect of crystallization reaction. In the aging property, as the CR content increases, the changed amount of basic properties were decreased, which acts as a reducing factor in change of aged property by complementing weak point in mechanical property. It was found that the degree of property change for surface treated samples were reduced. According to the microscopic result, the degree of surface dispersion on rubber blends was increased by increasing CR content. Rubber surface showed uniform direction in pattern with increased smoothness and luster by treatment with chlorine. The degree of rubber reforming was measured by the remaining amount of chlorine and the friction coefficient was dependent on the amount of chlorine combined with rubber. In the initial stage of surface treatment, from 10 to 40 phr, the friction coefficient of specimen was rapidly reduced. However, as the concentration of chlorine solution increased, the change in friction coefficient was decreased.

Purpose The reference range described in Adrenocorticotropic Hormone reagent used in our laboratory is 10-60 pg/mL at 8 a.m. to 10 a.m., and 6-30 pg/mL at 8 p.m. to 10 p.m. However, in the case of outpatients, blood is mainly collected between 10 a.m. and 6 p.m., accounting for 57.8% of the total. Therefore, This study is intended to help make a more accurate diagnosis by reevaluating the reference range provided by the manufacturer of the Adrenocorticotropic Hormone reagent and setting split-timed reference range. Materials and Methods The patients collected blood before 10 a.m. were group A (68 people), and the patients collected blood after 10 a.m. were set to group B (80 people). A T-test was performed between groups to test their significance. And it was confirmed whether it was necessary to set the gender classification as a subgroup. The method of setting the reference range was calculated by the Bayesian's method and the Hoffmann's method. Results The reference range of Group A was 8.6 to 60.6 pg/mL by the Bayesian's method, and the Hoffmann's method was 3.6 to 61.3 pg/mL. The reference range of Group B was 6.9 to 50.5 pg/mL when applying the Bayesian's method, and the Hoffmann method's was 2.3 to 48.9 pg/mL. Conclusion This study was concluded that it was necessary to set the split-timed reference range. Through this study, the later the blood collection time, the lower the level of Adrenocorticotropic Hormone, indicating that blood collection time is important for patients with clinical significance. If a large number of subjects are selected and supplemented in the future, it is believed that systematic and accurate reference range can be set.

박지혜,서용철,PARK, Ji-Hye,SUH, Yong-Cheol 한국지리정보학회 2017 한국지리정보학회지 Vol.20 No.3

오늘날 도시성장과 인구밀집으로 인해 많은 대도시에서 빌딩숲이 생겨나고, 그로인한 쾌적한 거주환경에 대한 요구가 커지면서 일조권 침해에 대한 관심이 증가하고 있다. 이와 관련한 법규 및 관련분야의 연구가 수행되기 시작하였으나, 특정 전문기관에 의뢰 없이 일반인이 쉽게 건물 층별 일조권을 파악하는 데에 한계가 있다. 따라서 본 연구에서는 공간정보 오픈 플랫폼을 이용하여 도시음영지역 분석 시뮬레이션을 통한 건물 객체별 일조량을 산정하였다. 연구 대상지는 부산광역시에 위치하고 있는 해운대구 신도시를 대상으로 하였다. 이를 위하여, 해운대구 신도시지역에 대한 공간정보를 구축하기 위해 기 구축된 건축물 3차원 공간정보 데이터에서 건물높이를 추출하고, 태양의 고도와 방위각을 이용하여 3차원 도시 공간 음영분석 시뮬레이션을 수행하였다. 건물의 각 객체별 일조권을 연속 일조시간과 총 일조시간으로 구분해 정량적으로 분석함으로서 일조권 침해 여부를 보다 정밀하게 간편하게 판단할 수 있는 방법을 제시하였다. Due to urban growth and increasing population density, many large cities contain building forests. Moreover, due to increasing demands for pleasant residential environments, there is growing concern over the encroachment of sunshine. Although research on related laws and other related fields is emerging, there is a limit to the extent to which the public can easily determine the amount of sunshine per building without referral to specialized agencies. Therefore, in this study, the duration of sunshine per building object was calculated via a simulation of urban shaded area using a spatial information open platform application programming interface. The study area was the'L'apartment complex located in the new city, Haeundae, Busan, China. To perform the duration of sunshine simulation for three-dimensional urban spatial objects, the building height was extracted from pre-built three-dimensional spatial information data, and the position of the sun was determined from calculations of the altitude and azimuth of the sun. This study provides a more precise and easier method of judging whether sunshine is impeded from reaching buildings by quantitatively analyzing sunshine and classifying the total duration of sunshine and the continuous duration of sunshine on each object.
