Purpose : The purpose of this study was to examine the effects of two single chest physiotherapies mechanically ventilated patients with acute lung injury. Method : Participants were 30 ICU patients depending entirely on ventilators without self-respiration. Each patients received two single chest physiotherapiesvibration palm cup percussion at hour intervals. Data were analyzed one-way ANOVA and Wilcoxon signed-rank test. Statistical significance was accepted at a p value less than .05. Results : ibration therapy, dynamic compliance and statics compliance demonstrated a significant increase immediately and remained increased until 30 minutes after chest physiotherapy. palm cum percussion therapy saturation showed a significant increase immediately chest physiotherapyut there were no significant differences in tidal volume, dynamic compliance and statics compliance. Conclusion : In this study, we analyzed the effects of oscillation method and palm cup percussion method separately for each type of chest physiotherapy. Nursing interventions that actively utilize vibration methods should be provided to patients with respiratory diseases.

본 연구는 울산항 인근 정박지 내 선박의 운항 패턴을 파악하고, 관련 법규 및 준수 실태를 대조하여 자율운항선박의 실제 운항 시에 부차적인 운항 수칙을 수립하는 데 목적을 두고 있다. 일반적으로 항행하는 선박의 해양사고 중 높은 비중을 차지하는 조우 상황에서의 운항 규칙과 관련된 법률이 정박지 내에도 적용되고 있다. 이러한 관점에서 관련 법규들을 토대로, 실제 정박지에서 항행하는 선박들의 운항 패턴들을 관측하였으며, 대부분 정박지 내에서 출항하는 선박들은 항로의 우측에 근접하여 운항하는 양상을 보이며 우측 항행을 준수하고 있음을 확인하였다. 또한, 정박지 및 항내에서 충돌과 같은 예치기 못한 사고가 발생하는 대표적인 운항 패턴들은 정면 조우 상황, 방파제 내 출항 선박 회피, 우측 항행 등으로 분류되며, 정면 조우 상황과 방파제 출항 선박 회피의 경우에는 관련 법규를 준수하며 항행하는 것을 확인하였으나, 우측 항행 상황에서는 조우 상황에 따라 부득이하게 이행할 수 없는 경우가 발생함을 확인하였다. 본 기초 연구를 통하여 정박지 및 항내에서의 항행하는 선박의 운항 패턴을 자율운항선박에 적용 가능성을 타진하고, 항해 지원이 가능한 운항 수칙을 새로 정립하는 데 활용하고자 한다.

최근 문화유산 해설 분야에도 AI를 도입하기 위해 여러 노력을 기울이고 있으나, 관람객의 특성이나 관심사를 고려하지 않고 사전에 수동으로 입력한 동일한 문화해설 콘텐츠를 다수의 관람객에게 반복 전달하는 형태로만 제공되는데 그치고 있다. 본 논문에서는 관람객이 관람 중인 문화유산을 관람객의 다양한 관심사에 맞추어 문화유산을 다양하게 해설해주기 위한 기초 연구로 영상을 통해 입력된 한국 전통회화에서 도상을 검출하는 연구를 진행하였다. 아직 가능성 타진 연구로 진행되어 현재 제시된 실험 결과에서는 우수한 도상 검출 성능을 내지 못하였지만, 다양한 증강기법과 퓨샷 러닝기법을 통하여 성능 향상을 도모할 경우 충분히 관람객 맞춤형 문화유산 해설 분야에 활용 가능할 것으로 기대된다.

Production of crude glycerol from biodiesel industry is expected to exceed the commercial demand for purified glycerol in the near future. This study aimed to evaluate the feasibility of co-digestion of crude glycerol with swine manure. Crude glycerol up to 13.8 g/L was regarded as a good co-substrate for swine manure digester. It improved methane production and productivity by 90% and 120%, respectively. Methane yield of crude glycerol at the condition was estimated to be 232 mL/g. However, it inhibited methanogenic activity at above 27.5 g/L. Optimum concentration of crude glycerol for co-digestion with swine manure would be near to 13.8 g/L.

The double split Tee connection, a type of full strength-partially restrained connection, has adequate flexural strength according to the changes in the thickness of the T-stub flange and the gauge distance of the high-strength bolts. Moreover, the double split Tee connection is designed and constructed with seismic connections that have enough ductility capacity applicable to ordinary moment frame and special moment frame by grade of steel, size of beam and column and geometric connection shape. However, such a domestic research and a proposal of a suitable design formula about the double split Tee connection are insufficient. Thus, many experimental and analytical studies are in need for the domestic application of the double split Tee connection. Therefore, this study aimed to examine and suggest feasibility of a design formula of the double split Tee connection of FEMA.

The purpose of this study is to examine the possibility of crime prevention in consideration of urban physical environment by analyzing the spatial distribution characteristics and pattern using actual crime occurrence data of the case city. The crime data was rebuilt by transforming them into geographic information system to analyze the spatial aspect of crime occurrence. The findings are as follows: a change from 2008 to 2011 is indicated with similar trend. But the local movements of crime hot spots are found. Moreover crimes were happening along the roads in linear pattern rather than inside of blocks in commercial area. This indicates the importance of environmental improvement of roads and open spaces. In addition it was found that the crime occurrence in a dangerous district can be reduced and prevented through the physical environment design and urban planning. The findings will contribute to promoting fundamental crime prevention as the physical environmental improvement in a city and to building a safe community as its result.

This paper outlines the case of a 56 year-old man undertaking treatment by means of luxation and forced eruption of an ankylosed canine. At the time of diagnosis, the ankylosis of the tooth was not suspected, because there were not signs of intrusive luxation nor horizontal diaplacement. Only after the application of a vertical elastic force failed to erupt the maxillary left canine, was the ankylosis of that tooth suspected. At the time of reevaluation, the maxillary left canine hads no physiologic tooth mobility and emitted a sharp, ringing sound upon percussion. Hence, the maxillary left canine was considered ankylosed. The treatment course then changed to the extrusion of the canine through the surgical luxation of the tooth and the prompt application of vertical extrusive forces. The above outcome was successful for the patient not only in the orthodontic aspect, but also in terms of the periodontal considerations

Defamation is one of the most frequently occurring daily legal violation because it can easily be done by words. In the internet generation with flooding internet forum websites and social network services, internet defamation is becoming one of the most serious problems in many leading IT countries including Korea and the United States. Being such a critical issue that can lead to a suicide, Korean policy makers has undertaken efforts to prevent the internet defamation by defining the liabilities of internet users and internet service providers. Many of the policies and laws including "the Telecommunication Information Usage Promotion and Security Protection Act of 2007" are modeled after that of the United States. Thus, the study aims to explore American defamation law and internet defamation law analyzing "the Communications Decency Act of 1996" and a recently decided precedent, "Brodie" case, in Maryland state court.

This study was carried out to evaluate the dyeing possibility of purple corn stem and leaf. The UV absorbance of the purple corn stem extract and leaf extract at different pH does not change. It is considered to use to efficiently measure the purple corn pigment content when using UV absorbance at 520~560 nm. By adjusting higher pH values in the extraction dyed fabrics, silk and cotton fabric used by the purple corn leaf extraction decreased lightness and redness. Extent for dyeing the fabric depending on the concentration, lightness and redness showed a tendency to increase color values when silk and cotton concentration increases. Also when the longer the dyeing time, silk and cotton increased lightness but redness decreased.

Although the cement industry serves as the cornerstone of the construction industry by supplying one of its fundamental materials, it confronts new environmental challenges due to the problem of the $CO_2$ generated from raw materials and fuel used in the cement manufacturing process. Also, concrete structures can be decomposed and reused as construction materials. Simply in terms of the cyclic processing of $CO_2$, recycling waste concrete to manufacture recycled aggregate or recycling waste concrete powder, which is the material for cement can be considered optimally environment-friendly practices. This study contributes to the aim of manufacturing high value added materials that exploits the chemical properties of the waste concrete powder. From the research results, waste concrete powder is feasible to use to produce low carbon type recycled cement.
