  • To evaluate KR-10876, a new fluoroquinolone antibacterial agent, its effects on the central nervous system(CNS) were investigated in mmice as part of phamacological study, and the results were compared with those for ciprofloxacin and ofloxacin, two prototypes of quinolone antiabctrial agents. All the parameters indicative of CNS function and acute toxicity were measured by close observation of the animals at regular time intervals after oral treatment of test compounds. KR-10876 did not have any effect on the parameters measured at lower does (100, 300 mg/kg, p.o.), it caused ptosis, suppressed spontaneous locomotor activity, hypothemia, and prolonged hexobarbital-induced sleeping time. KR-10876 also had a slight effect on motor coordination only at high dose. Simialr to ciprofloxacin, KR-10876 did not protect mice from pentylenetetrazol-strychnine-, and electroshock-inducedl convulsions at doses tested. These findings demonstrate that KR-10876 affects CNS functions only at high doses. The rank order for effects is ofloxacin$\le$KR-10876>ciprofloxacin.

  • The effects of surge arresters for protection of transmission systems against direct lightning strokes have already been investigated using the digital simulation program EMTP. Distribution lines are spanned on a much large area as compared to transmission lines, and therefore, are more often susceptible to lightning strokes. This paper analyzes the overvoltages on underground cable system against direct lightning strokes to the overhead ground wire using the digital simulation. The effects of lightning protection methods, such as lowering the grounding resistance and installing the surge arrester, for preventing overvoltages on underground cable system caused by direct lightning strokes to the overhead ground wire is investigated. Several schemes have been proposed to protect underground cables. This paper summarizes the main results of a study aimed at analysis of lightning overvoltages in variety underground feeders protected by metal-oxide arresters. This study will provide insulation coordination methods for reasonable system design in 22.9kV underground cable system.

  • Motivated reasoning refers to biased reasoning that is affected by motivation to achieve a particular result or goal. In this study, we attempted a theoretical study on motivated reasoning that hinders the development of scientific thinking and empirical study on actual context of motivated reasoning in the research experiences of next-generation Korean researchers in the field of science and technology. To be specific, literature reviews were conducted to explore the psychological meaning of motivated reasoning and its negative impact on scientific thinking and science research. To understand the substantial meaning and context of motivated reasoning in the field of real science and technology research, we conducted in-depth interviews with eight graduate students and one young science and technology researcher. As a result of the literature reviews, we found out that motivated reasoning can interfere with the proper theory and data coordination, which is the core process of scientific thinking at the individual level. At the socio-cultural level, it can lead to cessation of constructing scientific knowledge and it can act as a mechanism in the process of using science for specific socio-cultural beliefs or purposes, thereby hindering the development of science and technology based on rationale and objective scientific thinking. Quantitative analysis with in-depth interview data showed that graduate students and the young researcher's experienced motivated reasoning results in trying to protect prior beliefs, make hasty conclusions, protecting socio-cultural belief or rationalizing decisions made by their community. Their motivated reasoning could become an obstacle in constructing valid science and technology knowledge through appropriate theory and evidence coordination. Based on these findings we discussed science education for improving scientific thinking.

  • A Cut Out Switch (COS) is used for line protection and pole transformer protection in power systems. The COS used to protect the pole transformer is installed on the power side of the pole transformer to protect the electric equipment from fault currents. The COS is composed largely of a body and a fuse holder, and when the fault current is energized, the element of the fuse link in the fuse holder is melted to block the fault current. The arc generated when the COS fuse link is blown causes fire and noise, causing discomfort to residents in the surrounding area, and the arc flame can cause secondary damage to the peripheral device. In this study, a current-limiting COS fuse with improved overcurrent blocking performance rather than explosion type was developed to solve the arc and noise problems during COS operation. The overcurrent breaking performance of the current-limiting COS improves the reliability by developing a striker and COS fuse bracket. In addition, this study aimed to verify the performance of the developed current-limiting COS fuse through a test at an authorized institution.

  • The scope of fire services has been expanded from local fire prevention to rescue and first aid services, and the fire services system has been converted from an autonomous fire services system to a wide-area fire services system, and the status of fire officers has been unified as a national public servant. However, the underlying problem remains unsolved. One is a problem related to the conversion of fire services to state affairs, and the other is that Fire officers converted to national public servants are in charge of fire services which are evaluated as local autonomous affairs. The controversy over the nature of fire service stems from uncertainty and redundancy in the coordination of office function and distribution between the State and Local governments, and incomplete legislation that fundamentally fails to achieve systematic unity of office work and status. The fire service has a national responsibility as an affair that includes the existence of the state and the welfare and order of the people along with the police affairs. That is, affairs related to the safety of the people that protect the lives, bodies and properties of the people should be understood as State affairs. 「The LOCAL AUTONOMY ACT」 stipulates that local governments cannot perform State affairs such as affairs necessary for the existence of the nation, affairs requiring performance in a uniform manner throughout the nation, and affairs of nationwide or similar scale unless otherwise provided by the law. Fire Service should be regarded as such affairs. Considering that the rights to the safety and life of the people and the duty to protect the people are the duty of the nation, it is necessary to keep in mind that the reason for the change fire officers to the national public servants was not basically just a matter of treatment and finance.

  • The AC power lines and signal lines of info-communication networks are muted on overhead poles and are exposed to lightning strikes. Due to the potential difference between groundings of the AC power lines and telecommunication lines, the electronic equipments connected to the telecommunication lines can easily be damaged by lightning surges. In this work, in order to develop the reliable ways to protect information and communication facilities from lightning surges, the reliability and performance of surge protective devices were experimentally investigated in actual-sized test circuit. The operation behaviors of surge protective devices against lightning surges from the AC power lines and telecommunication lines and the coordination effects of SPD installation method were evaluated. As a consequence, it was confirmed that the bypass arrester and common grounding system is very effective.

  • This study was conducted to investigate how to apply the theories of oriental medicine appropriately, which direction should be taken, and how it should be developed The results are as follows. First, to develop medicinal cuisine, it is necessary to grasp the theoretical system, considering Ohaeng and Omi, the five viscera and the six entrails, organs and body, by raising the level of understanding comprehensively about the relationship between the characteristics of each groups of Sasang Constitutions and the theories of Eumyangohaeng, and the relationship between the theory of Kimi. and food, and then to explain developed medicinal cuisine and apply those theories to inventing new ones. Secondly, to develop medicinal cuisine for health enhancement, it is also required not only to consider constitutions but also to suggest the need of knowledge for moderation in terms of regimen along with the theory of Kimi. Thirdly, to develop medicinal cuisine according to the perspective of Kimi. Theory, what should be taken into account is not only the understanding of the characteristics of food materials, but also the properties of them that the theory of Kimi, Eumyangohaeng, and Sasang Constitutions share so that it is possible to invent medicinal cuisine which is good for anybody to protect disease specific to a certain group of constitutions with, and serves as the dietary regimen customed to each constitution group. Lastly, the scientific effect of the medicinal cuisine which is developed according to the theory of Kimi., Eumyangohaeng, and Sasang Constitutions should be verified by scientific researches and clinical experiments. And it is believed to be essential for the government to make efforts to set a standard and laws to validate the medicinal effects and the process of assessment so that the systematic development can be encouraged, and to prepare guidance to food development for national health improvement.

  • In order to maintain and protect professionalism in color planning, the present study examined the process at the time of realization of color through color inspection and supervision in the actual construction site and suggested plans for improvement. Reflecting the characteristics that the governing body of the construction site is not a private person but an organization, the present study aims to provide institutional measures so that the supervisor of color construction at the actual site of construction can propose concerns related to proper construction at the right time, and the matters cannot be decided from the perspective of a layman. The institutional measures are proposed through the case of application of a process at the construction stage of the color planning at the construction site of Muju Taekwondo Park. First, the process clarified where the responsibility lies by specifying special conditions concerning color inspection on the field guide and color contract. Second, the sample for building materials was selected after obtaining it from a company capable of supply and is appropriate for the planned unit cost so that it could play an important role in realizing colors at the stage of basic design. Third, the process of construction was ensured not by temporary selection of colors but by continuous approval of colors in consideration of the conditions of construction site through letter of approval of color at each stage and point of time. Fourth, coordination of various color elements of other fields including landscape, interior, and electricity ensured construction of the whole structure in one color concept. Fifth, color inspection through the mock up of the site will minimize erroneous construction and reconstruction and prevent decrease in productivity. Sixth, this study also suggested more comfortable and positive color environment through evaluation by experts and users. The researcher of this study expects that color experts actively participate in the stage of construction to contribute to improvement of the color environment.

  • Small-to-medium retailers in local neighborhood have been managing to survive without outside influence. However rapid change in business environment including consumer needs for goods and the quality of life has brought turbulence into retail business. Petty retailers are facing a crisis as large-sized discount stores owned by big enterprises are entering into traditional markets. To protect small-to-medium retailers from such threats and revive the traditional commercial markets the government is taking on the policy of subsidizing small-to-medium businesses. However, recent emergence of SSM (an industrialized supermarket in forms of direct management and affiliation) in local commercial areas has brought about conflicts and frictions between large companies and local merchants. Under this background this study attempted to make an analysis of vulnerable factors of small-to-medium retailers coping with SSM and probe for the alternatives to SSM business restructuring.

  • Clothing is intimately intertwined with daily lives as every individual relies on it. The pervasive issue of plagiarism in the fashion industry has led to an increased demand to protect intellectual property rights. Currently, studies on the protection of fashion design intellectual property rights in China remain in the exploratory stage and warrant further investigation. This paper addresses the issue in two parts. The first part contains an analysis of the theoretical foundation for the protection of fashion design copyrights. It is further divided into three subsections. The first subsection primarily examines the concept of copyrights and laws. The second subsection focuses on the concept of fashion design copyrights and laws. The third subsection analyzes copyright laws concerning fashion designs in China. The second section offers an analysis of infringement cases involving fashion designs published during the Baiyi Cup Intellectual Property Case Summary Writing Competition held in China in 2023. It outlines the shortcomings of the current Chinese copyright laws regarding the protection of fashion designs, and proposes measures for improvement. This study argues that the institutional framework for intellectual property rights in the Chinese fashion industry should align with practical considerations and explores suitable legal regulations and how they relate to specific circumstances in China. Besides refining the legal framework, fashion designers and enterprises must take measures to entablish the intellectual property rights of their clothing brands.
