  • The discussion of intellectual property protection with TK, GR in WIPO begin Herbal medicines get a important basis in a development of modern new medicine. For the protection of intellectual property, we set up this study. For the protection of intellectual property with herbal medicines, We analyze as follows. First, we analyze the specific theory and character of traditional herbal medicines. Second, we analyze the existing system on protecting them in Korea. The intellectual property protection with herbal medicines must maintain the specific character of that. We must select the basic traditional herbal medicines. The next, we must protect from intellectual property on add and subtract, combine, create of the traditional herbal medicines. In order that we must construct database on the Herbal medicines.

  • 물성 정보는 연구활동 및 기술개발을 위해 아주 중요한 데이터이다. 그럼에도 불구하고 연구자들이 연구개발을 위해 이용하고 있는 물성정보 현황과 향후 연구자가 필요로 하는 물성정보 현황이 제대로 파악되지 못한 실정이다. 또한 물성정보의 생산 및 유통을 위한 인프라도 구축되어 있지 못한 상태이며, 연구자 마다 반복적으로 물성정보를 입수하기 위해 소요되는 시간과 비용도 적지 않다. 본 연구에서는 산업계, 연구계, 학계에서 현재 이용하고 있는 물성정보에 대한 이용실태를 조사하고 향후 연구자가 연구를 위해 필요한 물성정보 수요를 파악하고 이를 분석하였다.

  • This study aims to analyze the changes in the mechanical properties of woven fabrics(cotton, linen, wool, silk, and polyester) by bonding fusible interlinings with varying deniers(10D, 20D, and 30D) for a 3D virtual try-on system(one that a user to try garments through screens using Avatar) developed over the last decade. We experimented with four mechanical properties and thicknesses of twenty-three specimens of interlining bonded fabrics including face fabrics and interlinings by using the KES-FB-AUTO system. The results showed that the tensile property increased(LT and RT increased and WT decreased) as the denier of the interlining increased; however, the change was slight. In contrast, the bending and shear properties increased significantly as the denier of the interlining increased on both the warp and the weft. This showed evidence that the interlining gives the fabrics size stability. The compression property was slight changed as the tensile property varies depending on the fibers and the denier of interlining. As expected, the thickness increased by bonding the interlining as the denier of interlining increased. From these results, we conclude that 3D users need to reflect these changes of woven fabrics by bonding interlinings when they try screen fittings to accurately express the fabric reality of manufactured garment.

  • The physical properties of recycled polyester yarns according to recycling methods were investigated. Virgin polyester draw texturized yarn(DTY), material-recycled(MR) polyester DTY and chemical-recycled(CR) polyester DTY were prepared. Surface morphology, thermal property, micro-structure and mechanical property of recycled polyester yarns were estimated. SEM-EDS analysis showed that the CR PET yarn had better crimp and more stable structure than MR PET yarn. Tm of the MR PET yarn was higher than that of the CR PET yarn. The intensity of the crystallization peak of the CR PET yarn was a little higher than that of the MR PET yarn. Tensile strength of the MR PET yarn was slightly higher than that of the CR PET yarn. Breaking elongation of the CR PET yarn was slightly higher than that of the MR PET yarn.

  • The energy efficiency and bandwidth efficiency are two important criterion in designing a modulation scheme Especially the constant envelope property must be considered as in the non-linear channel tht exit, for example in the nonlinear amplifiers for satellite repeater. The Q$^{2}$AM(Quadrature Quadrature Amplitude Modulation) is a new modulation scheme which combines the Q$^{2}$PSK(Quadrature Quadrature Phase Shift Keying) scheme which increases the signal space dimension and the QAM scheme which increases the bandwidth efficiency using the multi-level signal. The Q$^{2}$AM scheme has by far superior spectrum efficiency compared with the existing modulation schemes. Applying this scheme in the non-linear communication system increses the bandwidth efficiency but cannot envelop property. In this paper, a new system architecture is suggested which satisfies the large spectrum efficiency and constant envelope property by implementing the linear block coding prior to the Q$^{2}$AM modulation. the system has improved in performance by gaining the constant envelope and the additional coding gain. We able to observe the performance improvement of the suggested system(at BER=10$^{-5}$ ) of 4.4 dB for the 16-QAM and 0.7 dB for the Q$^{2}$PSK under the exact spectrum efficiency.

  • Frictional sound is observed in great many practical systems, but its generation mechanism is still unknown Model systems are best suited for research on the fundamental mechanisms, but results cannot be easily applied to real systems, because each system has different sound radiation properties. At present, there is no easy method for evaluation of these properties. We propose to describe the sound radiation property of a tribo-system by the relationship between friction-induced sound power and the friction-induced vibration velocity of the contact element. It was found that the sound power of a tribo-system is linearly proportional to the mean-square velocity of the sliding element by a constant coefficient having the dimension of mass flow rate (kg/s).

  • In this study, evaluation system of the thermal properties of the exothermic agents was investigated. Exothermic agents property evaluation system was developed by metering variation of power supply. Thermal properties of exothermic agents was affected by material mixture condition of exothermic agents, however, it was not affected by temperature. It is possible to make various exothermic agents by means of regulating thermal properties which is based on property evaluation system of exothermic agents.

  • In this paper we examine cultural properties of the North Korea from 'the law of the Democratic People's Republic of Korea on Protection of Cultural Property". This law was adopted the Resolution of the Standing Committee of the Supreme People's Assembly of DPR of Korea in 1994. For our study, some other laws or rules established after the end of Japanese colonial occupation (1910-1945) in North Korea were examined. The policy on protection and conservation of cultural property in North Korea seems to have taken place a relatively rapid. The purpose of this law is to carry out the policy with a view to contributing to establishment of strict system and order for protection and management of cultural property, to their preservation in original state, to their proper inheritance and development, and to enhancement of national pride and confidence among the people. This law consists of 6 chapters (52 articles): (1) Fundamentals of the law on protection of cultural property, (2) Archaeological excavation and collection of cultural relics, (3) Evaluation and registration of cultural property, (4) Preservation and management of cultural property, (5) Restoration of cultural property, and (6) Guidance and control of cultural property protection. Nevertheless, it is difficult to find the evidence of efforts to exploit the cultural properties from an academic point of view in North Korea since the late 1980s.

  • Austomated visual inspection(AVI) capability has become an important key component in the automated manufacturing system. In such a visual inspection system an intensity(or color) image of a scene is quickly affected by optical property of objects, condition and roughness of surface, lens and filters, image sensor property and lighting system. In particular, the lighting system disign is the most important factor, since it affects overall performance of the visual system. For fast and cheap automated visual inspection system it is important to obtain the good image quality which results from careful attention to the design of the lighting system. In this paper, the lighting subsystem of AVI system is analysed for the inspection of printed circuit board(PCB) patterns. The spectral reflectance of materials, which are composed of PCB, is measured for choosing the light source. The reflection property is theoretically obtained by a reflection model and also obtained by experiments which measure intensity with varying the viewing direction of image sensor and the lighting direction of illuminator. The illumination uniformity of a ring-type illuminator. The lighting system is designed based upon the experimental results and theoretial analysis.
