The choice of suitable hip implant is one of important factors in the total hip arthroplasty (THA). In clinical view point, an improper adaptation of hip implant might induce abnormal stress distribution to the bone, which can shorten the lifespan of replaced hip implant. Currently, interest in the custom-designed hip implants has increased as studies reveal the significance of geometric shape of patient's femur in modeling and designing the implants. In this study, we have developed custom-designed hip implant models with various sizes, and analyzed the stress distribution in the bone and bone cement using the Finite Element Method. It was found that minimizing the gap between implant stem and femoral cavity is crucial to minimize the stress concentration in the bone.

Main theme of this study is the acceptance phase of western architectural culture in modern east-north asia through a series of actual survey and typological analysis of existing church buildings in modern Korea. China. Japan. For this study, 126 modern church buildings of Korea, China, Japan are selected. Also, main subject of this study has deal with the side of culture - thought which background of christianity acceptance and acceptance mind of acceptance main-body, culture adaptation and transformation based on characteristic culturalization of Korea, China, Japan. Especially, I would consistently tried to see the acceptance phase of western architectural culture according to differential acceptance mind of acceptance main-body based on characteristic culturalization of three countries. Conclusively, in the point of view of western architectural culture acceptance phase, it could be said that Korean church architecture had characterized as a blending phase of the two eclectic architectural culture. And in the case of china, as a coexistance phase of the two architectural culture with more western style-oriented. On the other hand, Japanese church architecture had characterized as a syncretism phase of the both traditional and western architectural culture, though it is eclectic style-oriented. Therefore, it is thought that different acceptance mind of western culture had main factors caused of differential acceptance phase, when the two architectural culture, the traditional and the western, encounters.

Recently, many techniques have been proposed to improve the noise robustness for speaker verification. In this paper, we consider the feature recombination technique in multi-band approach. In the conventional feature recombination for speaker verification, to compute the likelihoods of speaker models or universal background model, whole feature components are used. This computation method is not effective in a view point of multi-band approach. To deal with non-effectiveness of the conventional feature recombination technique, we introduce a subband likelihood computation, and propose a modified feature recombination using subband likelihoods. In decision step of speaker verification system in noise environments, a few very low likelihood scores of a speaker model or universal background model cause speaker verification system to make wrong decision. To overcome this problem, a reliable feature selection method is proposed. The low likelihood scores of unreliable feature are substituted by likelihood scores of the adaptive noise model. In here, this adaptive noise model is estimated by maximum a posteriori adaptation technique using noise features directly obtained from noisy test speech. The proposed method using subband-based reliable feature selection obtains better performance than conventional feature recombination system. The error reduction rate is more than 31 % compared with the feature recombination-based speaker verification system.

In this paper, we propose an effective tracking algorithm with an appearance model based on features extracted from a video frame with posture variation and camera view point adaptation by employing the non-adaptive random projections that preserve the structure of the image feature space of objects. The existing online tracking algorithms update models with features from recent video frames and the numerous issues remain to be addressed despite on the improvement in tracking. The data-dependent adaptive appearance models often encounter the drift problems because the online algorithms does not get the required amount of data for online learning. So, we propose an effective tracking algorithm with an appearance model based on features extracted from a video frame.

Kim Whan-ki is an unusual instance in Korean modern artists, who payed attention to emotional and expressive effects of colors. The color of Whan-ki's paintings have been recognized as linked with 'blue' in spite that he used colors within the category of 'Colors of Five Directions(五方色)', which are traditional oriental colors composed of red, lue, yellow, white, green and black. Kim Whan-ki unearthed upon similarity of Five Directions Colors to the three(five) primary colors which modern abstract painter like Mondrian layed down. Whan-ki switched the five directions colors to modern ones. Kim Whan-ki's dot painting in which pure and watery color is sucked in ground is modernistic adaptation from ink painting. He packs a dot with sky and earth, moon and stars, forest and tree, birds and flowers, friends at his hometown, wind, sound and so on. Putting tens of thousands of these shapes and colors into a dot is modernistic version from ink painting. In that point there is a possibility to say that 'dark blue' of the dot painting is 'Hyun-saec(玄色)'. Eventually we can make sure that Kim Whan-ki's view of Art originated in oriental philosophy and beauty.

Following conclusions were derived from researching various consumption caused after surgical operation. The meaning of surgery in HyungSang medical point of view is a big flaw of the original configuration. Therefore meaning, the loss of container to store something. Changes of the body after surgery can be formation of stagnated blood and abnormal cyst of the removed part and entangled undigested food and stagnant blood. After surgery when the symptoms become chronic or the patients develop side effects as they age, consumption and aging process begins. HyungSang medical treatments of consumption caused after surgery are the followings. We should prevent aging of the framework by using appropriate medication to make up for faults in Gall Bladder, Bladder type and six meridian type by considering its form, color, pulse and symptoms. Stability of emotion that can endure various mental stimulation is needed. Prevent stagnation, indigestion, obstruction and numbness by smoothing up the constructive energy and the defensive energy in the operated part. The Heart and Kidney should be under control and Stomach and Spleen should be reinforced so that food intake is accelerated and produce vital substances and Ki and blood. Eum blood and Yang Ki should circulate around the body well. Examine daily life and if small changes in skin complexion, appetite, sleep and excretion occur, also difference in adaptation of external stimulation and mental health occurs immediate treatment and care is necessary. Treatment of side-effects caused from both aging process and post-surgery in HyungSang's view point is considered better than other ways of treatment and will contribute in expanding the field of medical science.

Korea's five leading industries-chemical, automobile, shipbuilding, metal and electronics-have been the growth engines of the Korean economy for the last 30 years. However, with their performance weakening in the past few years, Korea's annual growth rate has dropped to less than 2%. Just as the Japanese economy struggled through the lost decades, Korea's leading industries have been facing signals of arriving at a Strategic Inflection Point ("SIP") since the mid-2000s. The objective of this study is to present an appropriate value strategy for Korean firms in leading industries to gain sustainable competitive advantages. This paper examines the following issues : First, it diagnoses the signs and timing of SIP for the five leading industries. Second, this study examines 78 Korean and Japanese firms in order to understand the adaptation strategies of the highest and lowest performing firms from a value strategy point of view. Third, it empirically analyzes the correlation between the indicators of value strategy and the accounting performances of the Korean and Japanese firms. The data set used in the cluster analysis were collected from KISLINE database of NICE Information Service and annual reports. The findings in the case analyses of high and low performing companies show that high value-added specialty chemical materials and electronic component manufacturers that had a strong focus on value creation were defined as high performing companies. And in the cosmetic and automobile industries, companies with a strong emphasis on value appropriation gained high performance. Furthermore, the study conducted a cluster analysis based on two indicators R&D and advertisement expense. The analysis shows that a significant gap exists in the operating incomes among three groups classified under the value strategy. The study recommends that Korean firms are requested to increase R&D expenditure, conduct M&A and collaborate with companies that own source technologies to narrow the technology gap and improve their segment portfolio from commodity to value-added products.
