Since July of 2012, the 3D video extension of H.264/AVC has been under development to support the multi-view video plus depth format. In 3D video applications such as multi-view and free-view point applications, synthesized views are generated using coded texture video and coded depth video. Such synthesized views can be distorted by quantization noise and inaccuracy of 3D wrapping positions, thus it is important to improve their quality where possible. To achieve this, the relationship among the depth video, texture video, and synthesized view is investigated herein. Based on this investigation, an edge noise suppression filtering process to preserve the edges of the depth video and a method based on a total variation approach to maximum a posteriori probability estimates for reducing the quantization noise of the coded texture video. The experiment results show that the proposed methods improve the peak signal-to-noise ratio and visual quality of a synthesized view compared to a synthesized view without post processing methods.

The purpose of this study is to analyze the factors which have formed gender images in men's fashion since the middle of the 19th century. For this purpose, the images of gender in fashion were analyzed and historical studies about gender images in men's fashion from the middle of the 19th century to the present days were done. Historically images of gender expressed in fashion were masculine image feminine image androgynous image and genderless image. Among those images masculine image and genderless image. Among those image masculine image and androgynous image have been the gender images in men's fashion since the middle of the 19th century. In psychoanalytic view point the factors which have formed the gender images are related with sexual pleasure. Libido for looking narcissism and exhibitionism have produced masculine image and androgynous image in men's fashion, In socioeconomic view point power structure between the sexes have built the gender images in fashion. Masculine image and androgynous image came in to being in men's fashion for the purpose of displaying power or expressing opposition to power structure between the sexes, In aesthetic view point the aesthetic sense of each age about sex have constructed the gender images. Modernism had influence on building masculine image and post-modernism have formed androgynous image in men's fashion.

The continuing need for more compact and reliable switching power supplies have aroused a renewed interest in a well founded control technique the Magnetic Amplifier(Magamp). Magamp have some advantages of higher power density simple control circuit, good regulation, high frequency and high performance. The control method with magamp become attractive solutions for high current post regulated output applications. In this study, it is proposed that the magamp technique in flyback converters with multiple output windings. Operation principle of the proposed approach is described and a description of magamp control loop behavior is given first from a circuit level point of view. Then the focus is shifted to look at the same issue from the block diagram point of view. Experimental verifications on 50W multiple output flyback converter are conducted. Simulations and experimental results show that the proposed approach is high efficiency and voltage regulation of the auxiliary output is excellent.

Purpose Recently, many organizations are actively adopting enterprise architecture (EA) as a methodology to manage IT assets and build IT-based business system. This study intended to empirically examine how the role of EA operating unit and utilization capability of organizational members impact on system performance at the post-adoption stage. A balanced score card (BSC) is being used as a framework for a company's key performance indicator (KPI). Design/methodology/approach This study tried to investigate the causal relationship between the four perspectives of the balanced scorecard as an influencing factor of the introduction of the Enterprise Resource Planning (ERP) on the financial value. In particular, the mediating effect between the customer's point of view and the business process point of view was investigated between the learning growth point of view and the financial point of view, and the interaction effect (regulating effect) of strategic linkage in the system introduction process was investigated. Findings The results of the study were first, that the organizational learning and growth perspective had a positive effect on the customer perspective, business process, and financial perspective. In addition, the customer perspective and the process perspective also had a positive influence on the financial perspective. Second, between the learning growth and financial perspectives, the customer perspective and the process perspective showed a partial mediating effect. Third, as for strategic linkage, the interaction effect between the customer perspective, the learning growth perspective, and the process perspective and the financial perspective was not significant. The results of this study are expected to provide a framework for performance evaluation to organizations that have introduced ERP systems.

The purpose of this study is to analyze characteristics of prospect from the mountain pass by investigating relations between the type of mountain pass and object overlooked from the mountain pass. For the purpose, this researcher selected and surveyed 44 mountain passes located in Busan, except in Gangseo-gu lesion. According to their locational characteristics, the mountain passes were classified into three types, 'sanmok'(formed between mountain peaks), 'sanheori'(formed on the mountainside) and 'sanmaru'(formed at the tip of the mountain peak). Out of the total 44 mountain passes, 22 were 'sanheori' in type. In the same type, mountain passes mostly had a prospect providing the overlap of downtown and mountain areas. The researcher examined the sight distance and dip of object to be viewed from the mountain pass, determining relations between the object and the mountain pass. When overlooked from mountain passes in Busan, most objects are distributed between $-3^{\circ}\;and\;-1^{\circ}$ in an angle of depression within the sight distance from 0.5km to 14km. Mountain passes are valuable as a post that is very important in prospecting scenes. But they are now in crisis. They are being gradually disappeared because of development projects. Finally, the researcher hopes that the study makes recognizing the value of the mountain pass and contributes to preserve the mountain pass as an important post of view point when its region is later developed.

The paper analyzes reactive power flow characteristic in power system by reactive power tracing. In addition, virtual buses are inserted in the algorithm to consider losses of transmission lines, and shunt capacitor treated as a reactive power generator. The results of simulation are analyzed by two points of view. The one is load’s point of view and another is generator’s point of view. Classic purpose of the reactive power tracing consists in the reactive power pricing. However, it is significantly used to select vulnerable area about line outage in this paper. To find the vulnerable area, reactive power tracing variations between pre-contingency and post-contingency are calculated at all load buses. In heavily load area, buses which has highest variation become the most vulnerable bus. This method is applied to the IEEE 39-bus system. It is compared with voltage variation result and VQ-margin to verify its effect.

We came to the conculsion after considering all of information from many kinds of books on the cause, pathogenesis and treatment of Flaccidity-syndrome. The results were as follows : 1. Flaccidity-syndrome means limb-relaxation due to muscle atony that isn't able to constraction. It's begun as mild degree from extremities, in some cases ended to quadriplegia or expire. 2. Cause factor and pathogenesis of Flaccidity-syndrome is various. After Lung fluid consuption caused by heat-evil was refered in The Yellow Emperor's Canon of Internal Medicine. They were refered as cause factor that Main channel asthenia, excess of sexual intercourse, wetness-evil, heat-evil gets into the interior, asthenia of the spleen and stomach. Since Ming Dynasty, It's classified to wetness-heat evil, wetness-phlegm, deficiency of vital energy, deficiency of blood, deficiency of yin, blood stasis and indygestion, etc. 3. In the view of treatment of Flaccidity-syndrome, Yangming was selected in The Yellow Emperor's Canon of Internal Medicine, and it's been mean to clear away wetness-heat evil located at Yangming. In the method of acupuncture it was same on the base, and many skills have been used that electronic acupuncture, point-injection theraphy, acupuncture point block, catgut implantaion at acupuncture point, cutaneous acupuncture, auriculo-acupuncture and head acupuncture by the through post generation. 4. Flaccidity-syndrome was defined to weak, disuse and non-pain. Beacause it was non-pain, so medicine to expel wind-evil was prevented to use. But through post generation Flaccidity-syndrome has been treated that is able to cause pain or numness as arthralgia-syndrome. Therefore there is tendency that medicine to expel wind-evil is capable within pathological basement of Flaccidity-syndrome in recent. 5. In the view of west-medicine, Flaccidity-syndrome is diplegia or quadriplegia with sensory disorder, muscle atropy in some cases. And there are spinal disease, peripheral nerve disease, muscular disease, nerve-muscle copula disease. The symptoms are able to amyotomia, numness, sensory disorder, pain.

The huge amounts of wastes were produced nowadays. Among the solid waste stream, the waste plastic portion is about 20 % in weight, over 50 % in volume. But the most of waste plastics were incinerated or land filled. Only a bit of waste plastics were recycled and reused. On the view point of current energy crisis, this will be an extravagance of beneficial resource. So we should consider the waste plastics as a beneficial raw material. Also need to develop the field of reusing and recycling of post-consumed plastic. In this context, present paper describes the methodology for enhancing or improving the specific properties by way of using inorganic filler waste. Also develop the product from these post-consumed plastic.
