Purpose: This study was performed to systematically review the recently published nursing intervention studies. Methods: The literature was identified through the Korean Education and Research Information Service (KERIS), the Korean Information Service System (KISS), and National Assembly Library websites. Key words such as breast cancer, nursing, and intervention were used. The factors analyzed are as follows: 1) the characteristics of studies and study populations, 2) the classification of interventions, 3) outcome indicators and their effects, and 4) effective interventions. Results: Thirty two studies were included. Seventeen studies used a single intervention such as aerobic dance, TaiChi, foot massage, aromatherapy, or a stress-reduction method. Fifteen studies used combined interventions, including education, exercise, counseling, support, yoga or meditation. The data on 47 outcome indicators and their effects were segregated into psycho/spiritual outcomes, stress coping, physical outcomes, cardiorespiratory function, symptom management, arm and shoulder functions, fatigue, and quality of life. Some interventions had positive effects on stress, fatigue, and functions of shoulder. Conclusion: Various interventions are available for breast cancer patients, and some have had positive effects. However, more studies are required to develop evidence-based practice guidelines for nursing interventions.

The recent works of architecture and interior design take on too various aspects to be classified as a trend or tendency. Many subjects, seeking the superiority between form and function in space which was the issue of Modernism, got to face the works which transcend the limitation of architecture due to the development of a variety of media and technology these days. In result, we could see the works which are to be Included into the category of art rather than architecture. This study starts from the thought that the common aspects of these works are based on the strangeness to pursue uniqueness, peculiarities or novelty. 'The subject of this study, $'D\acute{e}paysement'$, creates a new relation, disconnected from customs, to an architecture which became familiar through defragment, fixation and abstraction by the habitual relation and makes it reborn as an architecture which gives us a fantasy and a pleasure, by converting into the shape and image which are different from its original shape when a stimulus is given to an architecture. This study starts from the artistic aspect which has a close correlation with the architecture. The subject, $'D\acute{e}paysement'$ could be historically considered in two aspects - $D\acute{e}paysement$ of Surrealism which developed in paintings and Defamiliarization of Russian Formalism in the area of literature. This study is carried in a category of $D\acute{e}paysement$, focusing on the visual aspect of the architecture. This study is composed as follows: In chapter 2, a theoretical research is performed according to the definition and meaning of the $D\acute{e}paysement$ expression techniques, its origination and evolution, and type classification by the features of expression techniques in the era of Surrealism when $D\acute{e}paysement$ developed most vigorously in the area of art. In chapter 3, the system which formalizes the expression method of the techniques is presented, focusing on the case analysis of the artistic works according to the types of $D\acute{e}paysement$. In chapter 4, the application of the expression techniques of $D\acute{e}paysement$ is discussed by conducting cases analysis of the modern interior design.

Purpose: The purpose of this study was to provide quantitative data regarding development of the chest wall in children with cerebral palsy (CP) according to Gross Motor Function Classification System (GMFCS) levels and age using the radiological image diameter measurement method. Methods: Subjects included 112 children with CP and 110 healthy children, All of the children underwent simple chest x-ray. The diameters of the upper chest ($D_{apex}$) and lower chest ($D_{base}$) were measured on the anteroposterior (AP) view of a chest x-ray, and the $D_{apex}$ to $D_{base}$ ratio was calculated. Chest wall ratios were compared among children with CP at GMFCS levels I ~ III, GMFCS levels IV and V, and healthy children. Results: The results showed significant differences between the upper and lower chest wall diameters of children with CP at GMFCS levels IV and V, and healthy children (F=4.54, p=0.01; F=3.20, p=0.04). Results of comparison between the chest wall ratios of children with CP and healthy children, showed that the upper chest walls of healthy children were significantly larger in children younger than 48 months (p<0.05), and both the upper and lower chest walls of healthy children were significantly larger compared to children with CP in children older than 48 months (p<0.05). Conclusion: Radiographic measurement for examination of chest wall development is relatively simple, and the results yield quantitative data on development of the chest wall for children with CP. In addition, therapeutic interventions may be considered based on the results.

The smart substation is the heart of a transmission system, which is particularly emphasized as the most significant composition of smart grids in China. In order to assess the functionality performance of substation technologies, this paper presents methods used to identify the most promising solutions for smart substation design and to evaluate the technical levels of available technologies. The multi-index optimization model is presented to address the issue of smart substation planning. A mathematical model of the planning decision problem is established with multiple objectives consisting of economic, reliability, and green key indices, and many kinds of concerns including physical and environmentally friendly operations are formulated as a set of constraints. With respect to the assessment of the technical level regarding integration of advanced technologies into a substation, a modified grey whitenization weight function is adopted to structure a novel grey clustering method. The proposed grey clustering approach is used to overcome the difficulty of insufficient quantitative assessment capacity for traditional methods. The evaluation of technical effects provides the classification definition for the development phase and the maturity level of the smart substation. The effectiveness of the proposed approaches in planning decision-making and evaluation of construction efforts is demonstrated with case studies involving the actual smart substation projects of Wenchongkou substation in China Southern Power Grid (CSG) and Mengzi substation in State Grid Corporation of China (SGCC).

New images percolate through human consciousness by the media such as movies, TV programs, and brilliant advertisements. These images reproduce new ' things ' throughout the ' semantic processes ' by those who experience and recognize them. Alvin Toffler describes it as the ' information bomb ' and ' image fragments ' in his talk about the new paradigm of information-oriented era. The increasing number of images and their accelerating rate of appearance imply that images become more momentary, and are evidence that they are transforming entire human life and consciousness. Such awareness means a lot to a designer. Especially, the subject that how modern space-dominating images are related to the structure and materials constituting the space and communicate with human mind will be an important factor in establishing the human-space relationship in the future. Furthermore, the present age overspread with various medium is not the only one privileged of the images that exist within space. They are the results of continuous expansion of existing images, and also process of evolution of space powered by the fusion of images and digital media. Imagified space is a boundary layer of Cyberspace, and the space itself becomes an interface by human recognition and participation. Now, the functional classification of spaces such as ' office, ' ' cafe, ' and ' school ' is meaningless. Whatever it may be, the function of a space is defined by the information it interfaces, and therefore it becomes an interface to information through a large number of images. Based on this idea, we will observe the imagificaiton of space in the form of discussion, and from that, try to understand the phenomenon through the real world examples.

Early detection of the pulmonary nodule is important for diagnosis and treatment of lung cancer. Recently, CT has been used as a screening tool for lung nodule detection. And, it has been reported that computer aided detection(CAD) systems can improve the accuracy of the radiologist in detection nodules on CT scan. The previous study has been proposed a method using Convolutional Neural Network(CNN) in Lung CAD system. But the proposed model has a limitation in accuracy due to its sparse layer structure. Therefore, we propose a Deep Convolutional Neural Network to overcome this limitation. The model proposed in this work is consist of 14 layers including 8 convolutional layers and 4 fully connected layers. The CNN model is trained and tested with 61,404 regions-of-interest (ROIs) patches of lung image including 39,760 nodules and 21,644 non-nodules extracted from the Lung Image Database Consortium(LIDC) dataset. We could obtain the classification accuracy of 91.79% with the CNN model presented in this work. To prevent overfitting, we trained the model with Augmented Dataset and regularization term in the cost function. With L1, L2 regularization at Training process, we obtained 92.39%, 92.52% of accuracy respectively. And we obtained 93.52% with data augmentation. In conclusion, we could obtain the accuracy of 93.75% with L2 Regularization and Data Augmentation.

The aim of the present study was to analyse grunts of the sows and to extract parameters from the time and frequency signals in nursing behavior. Five crossbred $Landrace{\times}Yorkshire$ sows were used on day 5 or 6 postpartum. The grunts and the behaviors of the five sows were recorded with five digital camcorders. Three parameter groups [Group I: Formant vector alone, Group II: Formant vector+parameters from time signal, Group III: Formant vector+parameters from time signal-parameters eliminated by stepwise discriminant analysis backward (SDAB)] with parameter vectors extracted from single grunts in the maximum grunting rate period were used for individuality of the sows. The parameter groups were compared by a discriminant function analysis. The classification system adopted in the Group II represented the higher discriniation rate than those in other groups (Group I: 63.3%, Group II: 83.0%, Group III: 80.0%). This study demonstrated that formant, intensity, and pitch were available sound parameters for individuality of the sows during nursing behavior.

The applicability of Diabetes Mellitus(DM) in Oriental Medicine might be placed under the category in Wasting-thirst(消渴, WT). However, because of WT having so various concepts, classification, and names in Oriental Medicine, this resulted in confusion in applying WT treatment to DM. WT occurs mainly due to dryness-heat(燥熱) which by depleting 'Fluid and Humor'(津液) makes symptoms of thirst(口渴) swift digestion with rapid hungering(消穀善饑) frequent urination(小便頻數) according to the "Internal Classic"(內經). WT was also called Sodan(消癉), Bidan(脾癉), or Sojoong(消中) in the "Internal Classic", which was caused by not only the disorder of 'five viscera' (五臟), but also the failure of 'three yin and three yang'(三陰三陽). However, the doctors of those days had a tendency to manage WT (including DM) with herbal drugs of dryness-heat or with drugs that recover the pancreas and the kidney, that have a tendency to appreciate that WT is the disease of 'five viscera'(五臟). Accoding to the "Internal Classic"(內經) and "Jinguiyaolue"(金匱要略), WT was appreciated that WT is also due to the disorder of Meridian including 'three yin and three yang'(三陰三陽) theory. Disorder of 'yang brightness'(陽明) or 'reverting yin'(厥陰) would cause Wasting-thirst(消渴), so the 'three yin and three yang'(三陰三陽) theory should be considered in WT treatments. Furthermore, 'yang brightness'(陽明) and 'reverting yin'(厥陰) all belong to 'the door'(闔) in the bolt-door-pivot(關闔樞) theory, and the mean of 'the door'(闔) is the function of storage, so we could understood WT is the wasting disease due to the disorder of 'the door'(闔) system in Meridian. WT should also be understood by the point of the bolt-door-pivot(關闔樞) theory in addition to the 'three yin and three yang'(三陰三陽) theory.
