  • In the era of the Nagoya Protocol, the way researchers have perceived genetic resources needs to change - genetic resources are no longer a common heritage of mankind. Many countries have recently amended their legal systems and are ready to adopt new legal procedures for access and benefit-sharing (ABS) of genetic resources to implement the Nagoya Protocol, claiming their sovereign rights over these resources for research use. Although both Korean government and academics have been striving to respond to the Nagoya Protocol, the understanding of ABS among researchers and the governmental guidelines for the use of genetic resources are not satisfactory yet. Researchers may perceive the implementation of the Nagoya Protocol as another burden for their research. However, it is evident that resource-rich countries are more likely to protect their genetic resources than other countries, and this tendency is expected to last long. Therefore, Korean researchers need to be prepared to minimize any damage that might be caused by ABS. This paper aims to raise awareness of ABS among Korean researchers by reviewing the key contents and overall structure of the Nagoya Protocol. It also identifies ABS procedures and presents specific measures for researchers to respond to the resulting changes in their research environments. Accordingly, this paper will serve as a guide for researchers to conduct research and development in accordance with the Nagoya Protocol.

  • The purpose of the study is to know the current status of the assets backed securities(ABS) in Korea. ABS enables banks, depository institutions, finance companies, and other corporations to liquefy their assets (i.e., raise cash by borrowing against assets) and develop new sources of capital. ABS are bonds that represent pools of loans of similar types, duration and interest rates. By selling their loans to SPC, the originator recover cash quickly, enabling them to make more loans. The ABS market in Korea has grown so rapidly since Financial Crisis in Korea. In current, So many different types of loans are securitized and sold in the investment markets. For more prospering ABS in Korea, some problems in ABS should be make up.

  • In this study, the PPS/ABS blend system was investigated in order to collectively identify the relationship among blend morphology, chemical compatibilization and thermal property. ABS resin was chemically modified by the incorporation of maleic anhydride through reactive extrusion for enhanced compatibilization, and PPS, ABS and the modified ABS were blend by a sing twin screw extruder. The effect of chemical modification of ABS on the morphological, mechanical, and thermal properities of the resulting blend was examined. A strong interaction was observed between PPS and MABS by optical microsopy as well as scanning electron microscopy, exhibiting a well-dispersed morphological feature. The PPS/MABS blend showing a single glass transition temperature was observed in dynamic mechanical analysis, demonstrating a pseudo-homogeneous phase morphology induced by chemical compatibilization. PPS/MABS blend also exhibited an enhanced thermal stability and heat distortion temperature compared with modified PPS/ABS blend.

  • We investigated resin, thinner, painting, and injection for analyzing the chemical effect of polymer, and made the optimum solution with the best performance of ABS (acrylonitrile butadiene styrene) resin. The effect depended on chemical material especially its chemical and physical properties instead of mechanical transformation. When we looked over ABS resin, injection, chemical material and painting, we found out thinner was the main factor for painting problem. Throughout this test, we could solve the problem, secure the system for control process and drop many factors for changing quality.

  • ABS/silicate composites with different clay types and compositions were prepared by in situ emulsion polymerization. The chemical structure of ABS was confirmed by the change of C-H stretching peak(near 3000 $cm^{-1}$) in fourier transform-infrared(FT-IR) spectrum. The thermal properties of the ABS/silicate composites were investigated by differential scanning calorimetry(DSC) and thermogravimetric analyzer(TGA). There was no distinct change in glass transition temperature of the ABS/silicate composites with different clay types. TGA curve indicates a dramatic increase in degradation temperature in case of ABS/20A composite with 3 wt% 20A. The silicate dispersion in the composites was measured by X-ray diffraction(XRD). The silicate dispersion in ABS/20A composites depended on the 20A composition. XRD results showed that the diffraction peak of the ABS/20A composite appeared when the content of 20A was higher than 5 wt%.

  • It has been known that interference occurs between macrocell ans small-cell base stations in a heterogeneous network (HetNet) of LTE-A. For solving this problem, 3GPP suggested eICIC (Enhanced Inter Cell Interference Coordination) that includes ABS (Almost Blank Subframe) and power control. This paper proposes to use ABS with power control and derives an effective ABS ratio as a function of the number of users and HeNBs. Through simulation, we confirm that integration of ABS and power control can mitigate interference than using ABS only. Furthermore, we verify that an effective ABS ratio is different depending on the number of users and HeNBs.

  • The effects of poly($({\varepsilon}$-caprolactone) (PCL) on poly(acrylonitrile-butadiene-styrene) (ABS) and polycarbonate (PC) blends were studied. Blends of ABS/PC (70/30, wt%) with PCL as a compatibilizer were prepared by a twin screw extruder. From the glass transition temperature $(T_g)$ results of the ABS/PC blends with PCL, the $T_g$(PC) of the ABS/PC (70/30) blends decreased with increasing PCL content. From the results of the morphology of the ABS/PC (70/30) blends with PCL, the phase separation between the ABS and PC phases became less significant after adding PCL in the ABS/PC blends. In addition, the morphological studies of the ABS/PC blends etched by NaOH indicated that the shape of the droplet was changed from regular round to irregular round by adding PCL in the ABS/PC blends. These results for the mechanical properties of the ABS/PC blends with PCL indicated that the tensile, flexural and impact strengths of the ABS/PC (70/30) blends peaked at a PCL content of 0.5 phr. From the results for the rheological properties of the ABS/PC (70/30) blends with PCL content, the storage modulus, loss modulus and complex viscosity increased at PCL content up to 5 phr. From the above results of the $T_g$, mechanical properties, morphology and complex viscosity of the ABS/PC blends with PCL, it was concluded that the compatibility was increased with PCL addition in the ABS/PC (70/30, wt%) blends and that the optimum concentration of PCL as a compatibilizer is 0.5 phr.

  • This study examined a fire accident caused by a defect in the vehicle ABS module. A large number of vehicles using the same manufacturer's ABS module in recent fire events showed a tendency to combust due to the same faults. As previously stated in the ABS module which shows the electrical breakdown between the power lines supplied to the constant power source by the battery. The electrical breakdown of the ABS module was caused by defects of the ABS module itself that were influenced by of the external flame. These results highlight the need to determine if there is a deficiency of the ABS module in the investigation of the cause of a fire in a vehicle which is produced by the same manufacturer.

  • ABS(Acrylonitrile Butadiene Styrene) 수지는 낮은 비중과 전기전도도, 가공성 등 우수한 물리적 성질을 갖는다. ABS 수지 제조방법인 Conventional process와 이를 개선한 MmSH(Momentary mold Surface Heating) injection process로 제조하여 나타나는 도금의 최적 조건을 연구하였다. 탈지, 에칭, Neutralization, Catalyzing, Accelerating의 전처리 과정을 거쳐 pH 변화에 따른 무전해 Ni 도금을 실시한 결과 각 수지 모두 pH7 이상에서 도금속도와 밀착력이 증가하였으나 MmSH injection process로 제작된 ABS 수지보다 Coventional process에서 제작된 ABS 수지의 밀착력이 우수한 경향이 나타났다.
