Since enactment of the Product Liability Act(PLA) on July 2002, Enterprises in Korea should be insured the Product Liability under the Act. Therefore they had to make a special team and organize it to match with the Act. However, some enterprises didn't follow and prepare the team for the dispute resolution. For example, in America, many enterprises had been attacked the PLA and in Japan, as well. but Korea is rare for the PLA. Thus, this is to research the PLA for protecting the disputes. Upon this study, 1 would like to suggest some issues and a revision of the PLA. Those are the purpose of my research. In this study, it consists of 5 chapters for achieving the purpose of the research. Introduction of this study is mentioned in Chapter 1, and Chapter 2 is for outline of the PLA in Korea. At Chapter 3, the cases are analyzed in the disputes of importers to address important things we have to check. After the analysis, resolution methods in general on import practices are suggested at Chapter 4. Also, this study is summarized at Chapter 5 including further research. In this research, 1 find out complex of Product Liability insurance and issues related with PLA. For protecting the issues and disputes; importers should prepare a agreement of arbitration during the preparation of contracts. Nothing can be better than prevention on any disputes, but they can be happened sometimes without any intentions or by mistake. Solving these issues, the resolution methods of this research are the most valuable. The mediation and the negotiation do not force any legal matters. So, the dispute through them does not have a positive resolution, and the effectiveness of them is very low. Due to the resolution of issues, arbitration is a desirable resolution. In Korea, most people do not know about the arbitration due to the lack of understanding of arbitration. Currently arbitration related with Product Liability has not been followed up promptly because procedures and judgement from a court take for a long time. In sum, in order to solve the disputes properly, they should be supported by the arbitration system to concrete essential objectives, so to speak, protection of the victim and the improvement of arbitration. In addition, the systematic arrangements would be required to carry out all the methods above mentioned. Those are for manufacturers, importers, and customers for the dispute resolution.

In this study, a series of site measurement of particulate and gases pollutants at five tunnels were carried out along with case studies to review the suitability of the current road tunnel ventilation design standards. Previous studies by other researchers have shown that the ratios of the level of measurement to the standard were 27.9%, 1.6% and 3.4% for TSP, CO and NOx, respectively. Those measured in this site study shows even lower ratios; the ratios were 2.6%, 0.8% and 0.3%, for TSP, CO and NOx, respectively. The particle size analysis of TSP for the five tunnels shows that PM10 including tire wear and re-suspended road dust exceeded 20.4%. This implies that non-exhaust particulate matter must be taken into account, since the current design standards for the particulate matter (visibility) include only the engine emission. Based on the recent research results, for vehicle emission rate and slope-speed correction factors, revision of ventilation design standards for pollutants is required. WRA (PIARC) also emphasizes the necessity of the ventilation design standards for pollutants. In addition, enactment of a new road tunnel ventilation system operation standard or guideline is strongly recommended when considering the low operating rate of the ventilation system with jet-fans.

Newly published IEC 60601-1-3 ; 2008 2nd Edition has two important meanings. First, Radiation Quality and Dose should make sure for safety of patient and staff in manufacturing diagnostic X-ray equipment. Second, it should be minimized of Leakage Radiation, Residual Radiation, and Stray Radiation. The requirement to make enactment or revision of national standard for diagnostic X-ray Equipment is as follows : 1. It should be adjusted the new standard to the recent IEC Publication under the consideration of the Korea medical circumstances. 2. For focus to the Radiation Safety, IEC 60601-1-3 (General requirements for radiation protection in diagnostic X-ray equipment) could be applied to the new regulation. It should be compact sentence. 3. A sudden Notification change should not be desired. It needs a enough time to make easy the circumstances.

Due to the revision of the River Act and the enactment of the Act on the Investigation, Planning, and Management of Water Resources, a regular bed change survey has become mandatory and a system is being prepared such that local governments can manage water resources in a planned manner. Since the topography of a bed cannot be measured directly, it is indirectly measured via contact-type depth measurements such as level survey or using an echo sounder, which features a low spatial resolution and does not allow continuous surveying owing to constraints in data acquisition. Therefore, a depth measurement method using remote sensing-LiDAR or hyperspectral imaging-has recently been developed, which allows a wider area survey than the contact-type method as it acquires hyperspectral images from a lightweight hyperspectral sensor mounted on a frequently operating drone and by applying the optimal bandwidth ratio search algorithm to estimate the depth. In the existing hyperspectral remote sensing technique, specific physical quantities are analyzed after matching the hyperspectral image acquired by the drone's path to the image of a surface unit. Previous studies focus primarily on the application of this technology to measure the bathymetry of sandy rivers, whereas bed materials are rarely evaluated. In this study, the existing hyperspectral image-based water depth estimation technique is applied to rivers with vegetation, whereas spatio-temporal hyperspectral imaging and cross-sectional hyperspectral imaging are performed for two cases in the same area before and after vegetation is removed. The result shows that the water depth estimation in the absence of vegetation is more accurate, and in the presence of vegetation, the water depth is estimated by recognizing the height of vegetation as the bottom. In addition, highly accurate water depth estimation is achieved not only in conventional cross-sectional hyperspectral imaging, but also in spatio-temporal hyperspectral imaging. As such, the possibility of monitoring bed fluctuations (water depth fluctuation) using spatio-temporal hyperspectral imaging is confirmed.
