This study is on system building and model case study to establish a new framework of "The Wild and Scenic Rivers System" and to apply this to Korean rivers. The Wild and Scenic Rivers System of the U. S. , which had become law in 1968 for establishing wild scenic and recreational river areas, was investigated. The techniques of two American case studies about the National Wild and Scenic Rivers System designation were investigated and synthesized, and study process was adjusted to Korean river system. Additionally, pilot study was carried out by the method and results were as follows : 1) In the American Wild and Scenic Rivers System, each river was evaluated based on eligibility criteria for designation, such as remarkable scenic, recreational, fish and wildlife, cultural or other ecological values. Segmented river areas were classified into three or four grades and management plans were prepared accordingly. 2) The management of rivers in Korea has emphasized on the flood control and water resources management up to the present, and now takes a growing interest in water quality. But it has been concerned very little with wild and scenic resources conservation of river corridors. It is strongly recommended to build Wild and Scenic Rivers System in Korea for rational management and conservation of the valuable natural resource. 3) Suggested evaluation criteria for the Korean Wild and Scenic Rivers System were wildness, wildlife and plants, hydrology, scenic quality, and historical and cultural resources. The river areas may be graded into four : Positive conservation area(I), Negative conservation area(II), Negative development area(III), Positive development area(IV). Management guidelines were proposed for each grade. 4) To test the applicability of the approach, one of the major tributary of the Han-River was selected for pilot study. The result showed that the evaluation and grading system worked well. Finally, it is recommended to incorporate the Wild and Scenic Rivers System into Korean national park system, and to amend the Korean National Park Act to enable this.

This study helps out-size consumers purchase tops and improve the fitness of unde-weight women in their 20s-30s and by the establishment of a size system. The criteria for subjects in this study were those under 18.5($kg/m^2$) of the BMI; subsequently, a total of 233 females were enrolled. The results were: First, the nominal size for female adult formal dress suggested by the KS standard is suggested in 20 sections. The sections for underweight women are 7, (34 women who accounted for 14.59% out of 233 in total). The cover efficiency was 2.08% (which was very low). Second, tests showed that the average difference between the reference part body size of 7 sections for underweight women in the normal size section of bust cir.- hip cir.- height, and KS standard, waist cir. among reference sizes was rather small in the case of a nominal size for long height. Therefore, there is a significant difference with size in the KS standard and a sizing system proven improper for underweight woman. Third, the basic body sizes and reference body sizes were different due to the size system establishment according to measurements of underweight subjects. The research findings suggest that it is necessary to understand underweight types according to bust girth and hip girth sizes that represent basic sizes as well as to design patterns that consider the underweight body shape characteristics when women's tops are designed.

The SiC-$ZrB_2$ composites were produced by subjecting a 40:60 vol.% mixture of zirconium diboride($ZrB_2$) powder and ${\beta}$-silicon carbide (SiC) matrix to spark plasma sintering(SPS). Sintering was carried out for 60sec at $1400^{\circ}C$ (designation as TP145 and TP146), $1500^{\circ}C$(designation as TP155 and TP156) and uniaxial pressure 50MPa, 60MP under argon atmosphere. The physical, electrical, and mechanical properties of the SiC-$ZrB_2$ composites were examined. The relative density of TP145, TP146, TP155 and TP156 were 94.75%, 94.13%, 97.88% and 95.80%, respectively. Reactions between ${\beeta}$-SiC and $ZrB_2$ were not observed via x-ray diffraction (hereafter, XRD) analysis. The flexural strength, 306.23MPa of TP156 was higher than that, 279.42MPa of TP146 at room temperature, but lower than that, 392.30MPa of TP155. The properties of a SiC-$ZrB_2$ composites through SPS under argon atmosphere were positive temperature coefficient resistance (hereafter, PTCR) in the range from $25^{\circ}C$ to $500^{\circ}C$. The electrical resistivities of TP145, TP146, TP155 and TP156 were $6.75{\times}10^{-4}$, $7.22{\times}10^{-4}$, $6.17{\times}10^{-4}$ and $6.71{\times}10^{-4}{\Omega}{\cdot}cm$ at $25^{\circ}C$, respectively. The densification of a SiC-$ZrB_2$ composite through hot pressing depend on the sintering temperature and pressure. However, it is convinced that the densification of a SiC-$ZrB_2$ composite do not depend on sintering pressure under SPS.

Cloud computing has been activated globally due to the demands of the 4th industrial revolution and the efficient use of IT resources, and domestic usage is also increasing due to legislation and related laws. However, domestic financial companies are subject to various regulations due to the importance of their information and the ripple effects of accidents such as outflows. Only non-critical information processing systems that handle non-critical information are allowed to use cloud computing. Financial companies are required to set specific criteria and judgment to distinguish them. In this paper, we propose a method to enable the financial company cloud computing to be more active by specifying the ambiguous non - essential information processing system designation standard and making it easier to designate.

Lidar-based hazard avoidance landing system for lunar lander calculates hazard cost with respect to the desired local landing area in order to identify hazard and designate safe landing point where the cost is minimum basically using slope and roughness of the landing area. In this case, if the parameters are only considered, chosen landing target can be designated near hazard threatening the lander. In order to solve this problem and select optimal safe landing point, hazard cost based on relative distance to hazard should not be considered as well as cost based on terrain parameters. In this paper, the effect of hazard cost based on relative distance to hazard on safe landing performance was analyzed and it was confirmed that landing site designation with two relative distances to hazard results in the best safe landing performance by an experiment using three-dimensional depth camera.

A recent air defense missile system is required to have a capability to intercept short-range super-high speed targets such as tactical ballistic missile(TBMs) by performing engagement control efficiently. Since flight time and distance of TBM are very short, the missile defense system should be ready to engage a TBM as soon as it takes an indication of the TBM launch. As a result, it has to predict TBM trajectory accurately with cueing information received from an early warning system, and designate search direction and volume for own radar to detect/track TBM as fast as it can, and also generate necessary engagement information. In addition, it is needed to engage TBM accurately via transmitting tracked TBM position and velocity data to the corresponding intercept missiles. In this paper, we proposed a method to estimate TBM trajectory based on the Kepler's law for the missile system to detect and track TBM using the cueing information received before the TBM arrives the apogee of the ballistic trajectory, and analyzed the bias of prediction error in terms of the transmission period of cueing data between the missile system and the early warning system.

If one wants to file a lawsuit against the administrative office, he or she should decide whether to file a civil lawsuit or an administrative lawsuit. The type of lawsuit must be determined to determine which court to file the lawsuit with. Korea seems to have a clear distinction between administrative and judicial legal relationships, but it is not easy to distinguish between public and judicial cases unless the public and judicial discrimination are maintained. The practice or precedent of litigation is always difficult to distinguish because the litigation is based on the discrimination of whether the litigation belongs to a legal relationship in public law or judicial law. I believe that if the administrative litigation law establishes a provision related to the designation of a duty and stipulates that "if a litigation case is questioned whether it is an administrative or civil lawsuit, the Supreme Court-related court shall designate the competent court at the request of the parties," the lower court will be guaranteed the right to swift a trial, and the legal representatives will be freed from the exhaustive agony.

Purpose: To discuss the records and legal standards of emergency medical technician training institutions in Korea and abroad, to identify the problems, and to provide the basic resources for improving the EMT-basic training institutions. Methods: We received advice through an advisory meeting of experts (professors of department of emergency medical technicians) and interested parties (Korean Association of Emergency Medical Technicians, officials of emergency medical technician training institutions) and referred to various reports published by governments, official institutions, and other trustworthy organizations. Also, we communicated with the related experts abroad (3 countries) on the phone or by email for surveys. Results: Compared to the abroad, it is necessary to categorize the standards and procedures of designating the emergency medical technician training institutions in Korea and improve the management of training institutions to train competent emergency medical technicians. Conclusion: It is necessary to designate and manage continuously the emergency medical technician-basic training programs for the systematic primary healthcare service.

Background: Some of the introduced alien species introduced settle, multiply, and spread to become invasive alien species (IAS) that threaten biodiversity. To prevent this, Korea and other countries legally designate and manage alien species that pose a risk to the environment. Moreover, 2160 alien species have been introduced in South Korea, of which 1826 animals and 334 plants are designated. The inflow of IAS can have negative effects such as ecosystem disturbance, habitat destruction, economic damage, and health damage to humans. To prevent damage caused by the inflow of IAS in advance, species that could potentially pose a risk to the environment if introduced in South Korea were designated as alert alien species (AAS). Results: The designation criteria were in accordance with the "Act on the Conservation and Use of Biological Diversity" and the "Regulations on the Ecological Risk Assessment of AAS and IAS" by the National Institute of Ecology. The analysis result of risk and damage cases indicated that mammals affect predation, competition, human economic activity, virus infection, and parasite infection. Birds have been demonstrated to affect predation, competition, human economic activity, and health. It was indicated that plants intrude on the ecosystem by competing with native species with their high-population density and capacity to multiply and cause allergic inducement. Interestingly, 300 species, including 25 mammals, 7 birds, 84 fishes, 28 amphibians, 22 reptiles, 1 insect, 32 spiders, 1 mollusk, 1 arthropod, and 99 plants, are included in the list of AAS. Conclusions: AAS designation plays a role in preventing the reduction of biodiversity by IAS in South Korea and preserving native species. Moreover, it is determined to provide considerable economic benefits by preventing socio-economic losses and ecological damage.

Background and objective: A biosphere reserve is a complex concept that combines the preservation of biodiversity and the sustainable development with the region, outstanding ecosystems with worth conserving in worldwide. The purpose of this study is to suggest the way of zoning that can perform the functions of conservation, development, and logistics support of biosphere reserves. Methods: To meet the purpose of this study, the designation criteria, restrictions, and permissions of the protected area specified in the law for domestic protected areas were reviewed to classify the functions of a biosphere reserve. Results: Through this classification, 10 domestic protected areas with high ecological protection value, such as the natural beauty of the ecosystem, biodiversity, and habitats for wild animals and plants were derived as the core areas of the biosphere reserves. Also, a total of 21 protected zones that can function as a buffer to protect the core of the natural ecosystem from indiscriminate development such as resource protection, recovery, pollution prevention, and improvement were derived as appropriate sites for a buffer. In the review process, issues such as different behavioral restrictions and ranges of permission due to the application of different laws were identified, if two or more protected areas exist within one of the protected areas, there is a protected area that does not meet the criteria for designating use zone, or where behavior restrictions do not meet the zoning criteria of biosphere reserve, under the laws of domestic protected areas. Conclusion: Although this study was not able to carefully review most of the laws on domestic protected areas that are linked to other laws, it was able to categorize appropriate domestic protected areas that can act as the core and buffer zones of biosphere reserves.
