Whole spine scanography(WSS)는 전신에 X선을 조사하는 검사로 치료기간 동안 빈번한 X선 조사가 이루어지는 검사이다. 일반촬영 분야에서는 많은 X선이 전신에 조사되는 검사이다. 따라서 논문에서는 Auto image pasta기법의 디지털 WSS 검사에서 환자의 검사방향에 따른 유효선량과 장기선량을 전산모사를 통하여 평가하였고, 영상에서 척추의 확대도와 각도의 변화를 평가하였다. 전후면 자세에서의 평균 유효선량은 0.069 mSv였고, 후전면 자세에서 평균 유효선량은 0.0361 mSv로 약 2배의 차이를 보였다. 전후면 자세에서 남성의 평균 유효선량은 0.089 mSv, 여성에 대한 평균 유효선량은 0.431 mSv로 나타났고, 후전면 자세에서 남성의 평균 유효선량은 0.050 mSv, 여성에서는 0.026 mSv로 나타났다. 확대율에서는 후전면 자세에서 전후면 자세에 비해 5%정도 확대 되었으나 각도에는 큰 변화를 보이지 않았다. 따라서 임상 환경에서 동일한 검사조건에서 환자의 자세를 변화시키는 것만으로도 환자의 피폭선량을 감소시킬 수 있음을 확인하였다. 특히 WSS와 같이 치료기간 동안 반복되는 검사에서 환자의 피폭선량 최적화를 위하여 검사 프로토콜의 재정립이 필요함을 확인하였다.

In human history, scarf has acted not only as a protection for body but also as a symbolization of class. Today, scarf has become a whole field in fashion and an important accessory to express individuality in fashion. Hence, like other fashion item, it is very important to develop exclusive design for scarf by analyzing the current fashion trend. In this research, we have designed a scarf textile, accordance with the contemporary design trend, applying the floral pattern, designed by William Morris who was an artist considered as the founder of the 1800s arts and crafts movement. We selected four trend themes, "Salon de Archives", "Eco Tech", "Profound Nature", and "Neo Aristo" for the design of 2007/2008 Fall/Winter. The flower motifs in Pimpernel Wallpaper, Honeysuckle textile design, Acanthus Wallpaper, Garden tulip wallpaper, Evenlode printed cotton, Trellis Wallpaper, and Chrysanthemum Wallpaper, by William Morris who expressed an image of environment friendly and nature reversion, applied to develop new creative scarf through design after modifying and rearranging these flower patterns. After the pattern was drawn by hand, adjusting of color and repeating of the design was done with DTP (Digital Textile Printing). Through this research, the researchers hopes to be of assistance to the development of national scarf brand design, and to the recapturing of textile industry that once played a important role in Koreans economic development.

Medical imaging techniques have evolved to expand our ability to visualize new contrast information of electrical, optical, and mechanical properties of tissues in the human body using noninvasive measurement methods. In particular, electrical tissue property imaging techniques have received considerable attention for the last few decades since electrical properties of biological tissues and organs change with their physiological functions and pathological states. We can express the electrical tissue properties as the frequency-dependent admittivity, which can be measured in a macroscopic scale by assessing the relation between the time-harmonic electric field and current density. The main issue is to reconstruct spectroscopic admittivity images from 10 Hz to 1 MHz, for example, with reasonably high spatial and temporal resolutions. It requires a solution of a nonlinear inverse problem involving Maxwell's equations. To solve the inverse problem with practical significance, we need deep knowledge on its mathematical formulation of underlying physical phenomena, implementation of image reconstruction algorithms, and practical limitations associated with the measurement sensitivity, specificity, noise, and data acquisition time. This paper discusses a number of issues in electrical tissue property imaging modalities and their future directions.

Background: Recently, cancer immunotherapy has become standard for cancer treatment. Immunotherapy not only treats primary tumors, but also prevents metastasis and recurrence, representing a major advantage over conventional cancer treatments. However, existing cancer immunotherapies have limited clinical benefits because cancer antigens are often not effectively delivered to immune cells. Furthermore, unlike lymphoma, solid tumors evade anti-cancer immunity by forming an immune-suppressive tumor microenvironment (TME). One approach for overcoming these limitations of cancer immunotherapy involves nanoparticles based on biomaterials. Main body: Here, we review in detail recent trends in the use of nanoparticles in cancer immunotherapy. First, to illustrate the unmet needs for nanoparticles in this field, we describe the mechanisms underlying cancer immunotherapy. We then explain the role of nanoparticles in the delivery of cancer antigens and adjuvants. Next, we discuss how nanoparticles can be helpful within the immune-suppressive TME. Finally, we summarize current and future uses of nanoparticles with image-guided interventional techniques in cancer immunotherapy. Conclusion: Recently developed approaches for using nanoparticles in cancer immunotherapy have enormous potential for improving cancer treatment. Cancer immunotherapy based on nanoparticles is anticipated not only to overcome the limitations of existing immunotherapy, but also to generate synergistic effects via cooperation between nanoparticles and immune cells.

The topic of this paper is the recognition of human activities using egocentric vision, particularly captured by body-worn cameras, which could be helpful for video surveillance, automatic search and video indexing. This being the case, it could also be helpful in assistance to elderly and frail persons for revolutionizing and improving their lives. The process throws up the task of human activities recognition remaining problematic, because of the important variations, where it is realized through the use of an external device, similar to a robot, as a personal assistant. The inferred information is used both online to assist the person, and offline to support the personal assistant. With our proposed method being robust against the various factors of variability problem in action executions, the major purpose of this paper is to perform an efficient and simple recognition method from egocentric camera data only using convolutional neural network and deep learning. In terms of accuracy improvement, simulation results outperform the current state of the art by a significant margin of 61% when using egocentric camera data only, more than 44% when using egocentric camera and several stationary cameras data and more than 12% when using both inertial measurement unit (IMU) and egocentric camera data.

Today, everybody lives in the stress. So 50% to 80% or 60% to 80% of the modern diseases are estimated what is caused by the stress. And one of the most important point of the stress is a too serious and continuos tension state. Therefore the best way to promotion, persistence, prevention and treatment of the modern man's health will be the relaxion from the tension state. The relax therapy as known as am effective method to the disease which as concerned with stress. that can be adapted to the treatment of anxiety-related diseases, insomnia, hypertension, tension headache, migraine, asthma, preparation of delivery, G-I disorders and menstrual disorders. Until now we guess the change of a relaxed state by the observation to the change of autonomic nervous system(ANS) and EEG. From the point of the ANS, sympathetic nervous system progresses slowly but parasympathetic nervous system increases the activity. In the EEG, both the alpha-wave concerned with the deep physical relaxed state and emotional stability and the theta-wave appeared in the state of meditation are increased. Current studies show that among the biochemical changes, especially serotinin like body hormone is increased by the feeling of the stability or the happiness. So, to see the change of the relaxed state in the image of the D.I.T.I., we used the deviational differences between the pre-relaxed state and the post-relaxed state of 70 people. As a result, the portional deviation of the face is decreased in the image of the D.I.T.I. So it can be thaught that we can determine the changes of the relaxed state by the D.I.T.I.
