The purpose of this study was (a) to develop carbon nanotube-based shock absorbers for reducing potentially harmful impact forces and excessive foot pronation, and (b) to briefly determine how the effects of carbon nanotube-based shock absorbers on biomechanical variance during drop landing. A university student(age: 24.0 yrs, height: 176.2 cm, weight: 679.5 N) who has no musculoskeletal disorder was recruited as the subject. Hardness, specific gravity, tensile strength, elongation, 100% modulus, tear strength, split tear strength, compression set, resilience, vertical GRF, and loading rate were determined for each material. For each dependent variable, a descriptive statistics was used for different conditions. The property test results showed that tensile strength, tear strength, split tear strength, compression set, and resilience in carbon nanotube-based shock absorbers were greater than general Ethylene Vinyl Acetate(EVA). These indicated that resistance against variable strength in developed carbon nanotube-based shock absorbers were greater than general EVA. In vertical GRF of CNTC was less than those of EVA during drop landing and loading rate of CNTC was greater than EVA. It seems that the use of CNT can be a effective way of reducing and controlling shock from impact.

In recent years, advanced in digital technologies have created significant changes in the way we reproduce, distribute and market Intellectual Property (IP). DRM for multicast contents is complicated risk, the further technology development and human demand, this approaching is still being researched by the scientist and all by the company which is conducting in piracy management reduced, and every country has national policy to make this consortium to limit piracy properties, based on this paper research development, just only two approaching to reduce piracy in DRM they are Industrial Property (IP) and Copyright. In this paper, we are not only figuring and analyzing about the processes to reduce and limit the piracy and unprotected copy law but also describing about the encryption process, watermarking and digital signature process algorithms. The basic concepts of this encryption process for web-based multicast content in DRM are implemented in Java. We conduct this method is a computerized through web based application system approaching to reduce unprotected copy and piracy. Which is used in DRM for multicast content in every section, by providing a fundamental in information technology development, we believe this research is reliable to prove that is unprotected copy, and piracy can be reduced by protecting with this paradigm.

The 21/sup st/ century is a society based on knowledge, so in economic activities, it has emphasized the importance of information such as intellectual property or intangible asserts. Especially, according to the agreement on trade related as parts of intellectual property rights in WTO, it is used as the method of commercial entente and monopoly for intellectual property in an advanced nation. For this reason, WIPO and UNESCO discussed a complement for intellectual property on the foundation of traditional knowledge such as traditional knowledge (TK), genetic resources (GR) and traditional cultural expressions (TCE, folklore). Korea has a lot of knowledge falling under TK, GR, and TCE because of the long history of the country. In the case of traditional medical care, it has been used in the public health system. It is hard to apply these rights to traditional medical care of Korea because the laws of intellectual property have been established under the ideas of western culture. It is necessary to improve the classification system of traditional knowledge and patents. In the patent classified system of IPC, it needs to be related to the research between the classified system for massive technology and the classified system for traditional clinic technology.

In this paper, a new method is proposed for robust proportional- integral - derivative (PID) control that is to ensure specified phase margin and iso - damping property using reduction model. This method is based on the second order plus dead time(SOPDT) reduction model of the high order model. Reduction model used to ensure iso-damping property in the feature frequency. Simulation results gives proof of effectiveness of proposed method.

In this paper, we obtain characterizations of continuous distributions based on the independent property of generalized record values extending the characterization results reported by Jin and Lee [4], Skřivánková and Juhás [8]. Also, example of special cases of general classes as Bur types, Pareto, power and Weibull distribution are discussed.

This study considers enlargement phenomenon in hair style as one of Costume types and analyzes its artistic characteristics based on the comparison between Hair style in the late Chosun Dynasty and that of the Rococo. First, its formative property, one of the common aesthetic characteristics, breaks the concept of traditional balance in Clothing and emphasizes its transformation, changes, and space beauty. This formative property shows the Enlargement and exaggeration beyond the concept of Space. Its sensuous property reflects women's psychological minds; exaggeration and sensualism. Artistic property doesn't focus on hair style only or clothing style only and considers hair style as renter of beauty as well as its important element. It shows the traditional beauty of nature and creativity in the Chosun Dynasty. Second, its formative property, one of the differential aesthetic characteristics, shows these following differences considering the aesthetic characteristics in the late Chosun Dynasty and that of the Rococo; mutual transformation, independent transformation, focus on distortion, harmony in scale, disharmony between irregularity and exception, extension and separation in space, etc. Sensuous property shows the temperate beauty and metaphorical sense, affected by the Practical Science, in the late Chosun Dynasty while it shows the secular sense and exaggerated beauty, affected by the Enlightenment, in the Rococo. Artistic property shows the harmony with the Clothing style, balanced wearing lines, and natural beauty, as one part of Clothing, in the late Chosun Dynasty. However it shows creativity, as separate part from Clothing, in the Rococo.

국내 문화재와 관련된 여러 재단은 해외 한국문화재 소장 기관의 협조를 얻어 국외소재 한국문화재를 조사하고 있고, 조사 결과는 보존 복원 및 전시, 교육 등의 활용기반이 되고 있다. 국외에서 한국문화재에 대한 연구조사 및 전시 등의 활용은 활성화 되어있는 반면 국내는 연구조사 결과를 통한 활용의 사례가 많지 않으며, 국외소재문화재에 대한 접근성 또한 낮다. 본 연구의 목적은 국외소재 한국문화재에 대해 국내에서의 활용할 수 있는 방안을 모색하는 것이며, 디스플레이 전시와 온라인 박물관은 국외소재 한국문화재를 활용할 수 있는 방안이 될 수 있을 것이다. 이를 통해 국외소재 한국문화재에 대한 접근성을 높이고 전시, 교육 등 다양한 분야로 활용할 수 있을 것이다.

In this paper, using B-splines as universial approximators, we have obtained a plant parametrization which permits the construction of an adaptive observer. The particular property of this parametrization is that the dynamic order of the filters in this design does not depend on the number of parameters in the plant parametrization. This appears to be a beneficial property especially because the number of such parameters tends to be very high for universial approximator based designs.

In general, estimates of average service lives and of mortality functions are less well-based than most types of economic statistics published by statistical offices. Therefore, hypotheses about service lives of tangible assets and their distribution are most difficult aspects to tackle. In this paper, estimates of service lives based on directly observed data on domestic industrial property and retirement rates are presented.
