  • SILER (Seismic-Initiated event risk mitigation in LEad-cooled Reactors) is a Collaborative Project, partially funded by the European Commission in the $7^{th}$ Framework Programme, aimed at studying the risk associated to seismic-initiated events in Generation IV Heavy Liquid Metal reactors, and developing adequate protection measures. The project started in October 2011, and will run for a duration of three years. The attention of SILER is focused on the evaluation of the effects of earthquakes, with particular regards to beyond-design seismic events, and to the identification of mitigation strategies, acting both on structures and components design. Special efforts are devoted to the development of seismic isolation devices and related interface components. Two reference designs, at the state of development available at the beginning of the project and coming from the $6^{th}$ Framework Programme, have been considered: ELSY (European Lead Fast Reactor) for the Lead Fast Reactors (LFR), and MYRRHA (Multi-purpose hYbrid Research Reactor for High-tech Applications) for the Accelerator-Driven Systems (ADS). This paper describes the main activities and results obtained so far, paying particular attention to the development of seismic isolators, and the interface components which must be installed between the isolated reactor building and the non-isolated parts of the plant, such as the pipe expansion joints and the joint-cover of the seismic gap.

  • The mechanical system of wearable walking assist robot needs to be optimized for adapting with human body structure and the planned control algorithm should have a secure procedure when a incongruity situation which can cause musculoskeletal injury occurs because a wearable robot is attached to a body. The understanding of walking or musculoskeletal motions characteristics must be preceeded and analyzed for developing novel wearable walking assist robot. In this study we tried to find out the capacities of powers and torques of joint actuators to design optimized performances of system and to obtain the analysis data to figure out the characteristics of joint movements during some types of walk. The major types of walk and motion are stair climbing and descending, sit-to-stand motion, and slope walking. In this study all these motions were analyzed experimentally except slope walking.

  • The purpose of this study was to verify the validation of effect on improvement of muscle strength unbalance according to exercise load deviation during rowing exercise. We performed evaluation of muscular activity and joint torque before the test. We recruited twenty subjects who one side's muscle strength is bigger in more 20% than other side. Subjects divided two groups. One is dominant left side and the other was dominant right side. Subjects performed rowing exercise in electric load deviation rowing equipment (Robo.gym, Humonic Co., Ltd., Daegu, Korea). Exercise performed four sets a day including 25 times a set, and three days a week. Measurements consist of evaluation of muscular activity and joint torque. Exercise load deviation adapted that different value of muscle strength in both arms multiplied 1RM% and added 1RM 50%. The results in adapted load deviation showed that the differences of maximal peak torque in 22.75% were getting increase significantly during exercise in 5.72%. This interpreted that rowing exercise with loading deviation types could provide muscle strength and muscular endurance exercise in same time for balance. Our study found out that loading deviation could provide muscle strength and muscular endurance exercise for improving muscle unbalance.

  • BACKGROUND/OBJECTIVES: Previous studies have reported that protein supplementation contributes to the attenuation of inflammation. Serious trauma such as burn injury usually results in the excessive release of inflammatory factors and organs dysfunction. However, a few reports continued to focus on the function of protein ingestion in regulating burn-induced inflammation and organ dysfunction. MATERIALS/METHODS: This study established the rat model of 30% total body surface area burn injury, and evaluated the function of blended protein (mixture of whey and soybean proteins). Blood routine examination, inflammatory factors, blood biochemistry, and immunohistochemical assays were employed to analyze the samples from different treatment groups. RESULTS: Our results indicated a decrease in the numbers of white blood cells, monocytes, and neutrophils in the burn injury group administered with the blended protein nutritional support (Burn+BP), as compared to the burn injury group administered normal saline supplementation (Burn+S). Expressions of the pro-inflammatory factors (tumor necrosis factor-α and interleukin-6 [IL-6]) and chemokines (macrophage chemoattractant protein-1, regulated upon activation normal T cell expressed and secreted factor, and C-C motif chemokine 11) were dramatically decreased, whereas anti-inflammatory factors (IL-4, IL-10, and IL-13) were significantly increased in the Burn+BP group. Kidney function related markers blood urea nitrogen and serum creatinine, and the liver function related markers alanine transaminase, aspartate aminotransferase, alkaline phosphatase, and lactate dehydrogenase were remarkably reduced, whereas albumin levels were elevated in the Burn+BP group as compared to levels obtained in the Burn+S group. Furthermore, inflammatory cells infiltration of the kidney and liver was also attenuated after burn injury administered with blended protein supplementation. CONCLUSIONS: In summary, nutritional support with blended proteins dramatically attenuates the burn-induced inflammatory reaction and protects organ functions. We believe this is a new insight into a potential therapeutic strategy for nutritional support of burn patients.

  • This study aims at developing ergonomics patterns for the sleeve of structural firefighting protective clothing through 3D motion analysis in order to ensure efficiency and safety of firefighters who are exposed to harmful environment at work. A new research pattern was developed by applying the total results of 3D motion analysis, changes of body surface length measurements, and 2D data on 3D body shape analysis on the size 3 patterns of the existing coat sleeve. For the sleeves, we used the body surface length of the range of shoulder's flexion and the joint angle of the range of wrist's ulnar deviation. And for the production of structural firefighting protective clothing using the research pattern, we recruited a recognized producer of structural firefighting protective clothing designated by KFI. Unlike everyday clothes, structural firefighting protective clothing should be able to fully protect the wearers from the harmful environment that threatens their lives and should not cause any restrictions on their movement. Therefore, the focus of research and development of such protective clothing should be placed on consistent development of new technologies and production methods that will provide protection and comfort for the wearer rather than production cost reduction or operational efficiency. This study is meaningful as it applied 3D motion analysis instead of the existing methods to develop the patterns. In particular, since 3D motion analysis enables the measurement of the range of motion, there should be continuous research on the development of ergonomics patterns that consider workers' range of motion.

  • Koreans have emphasized education as the primary means to reconstruct our country means to reconstruct our country after two catastrophic events-the Japanese occupation and the Korean War(1950-1953). A Strong belief- in education coupled with sheer deter-mination spurred the period of industrial and eeonomic development that started in the early 1970-'s. The "can-do" attitude of the general public was matched and aided by small S & T communities. Scientists and engineers provided the neeessary expertise to manufacture goods and process the many raw materials imported from overseas. After nearly three decades of reconst-ructing our completely devastated country, Korea has become a modern, cosmo-politan, fast-paced and dynamic country. In order to further increaser our manufac- turing capabilities and double the per-capita income by the beginning of the 21st century, we must improve productivitiy and encourage creatitivity in all sectors of our country. The S & T community's efforts in research and development. education, and interna-tional cooperation will be invaluable in determining our direction and reaching these goals. The general public is eager to peacefully unite our foreign powers since 1945. Toward that end. members of the S & T community are willing to coope-rate with our north Korean counterparts in all areas of S & T with the exception of defense related endeavors. Establi-shing scientific ties with north Korea will result in mutual economic benefit and greater regional stability in East Asia. In particular. scientists and manu-facturers in each province are eager to initiate cordial and professional relation-ships with north Korea in the hopes of securing these benefits. The Korean Federation of Science and Technology Societies(KOFST) has played an important role both in developing S & T policies, and in gostering the frowty of S & T societies. A non-governmental umbrella organization composed of over 251 professional societies, KOFST facili-tates the transfer of research outcomes and technology from research institutions to the various industries. KOFST also seeks to increase cooperation between the countries of the Pacific Rim. As evidence of that, we have pursued joint research and industrial ventures with China. Established projects include those on environmental conditions in the Yellow Sea, and improvement of aircraft manufacturing, telecommunica-tion equipment, and agricultural produ-cts. Increased cooperation between the Pacific Rim countries, particularly in S & T, would foster social and economic development for the region as a whole.

  • The purpose of this study is to identify professional development needs of Extension professionals and to evaluate competencies essential to be a successful Extension professional. For the purpose of this study, quantitative capacity data of extension professionals were collected from the survey instrument based on Extension Professional Evaluation Scale in Utah state university. Descriptive statistics, mean difference analysis, IPA(importance-performance analysis) analysis were used to analyze the data. The main results of the study are as follows. First, it is necessary to first reinforce education on specialized technical capacity among the three extension capacity areas. The current status of the professional capacity of extension professionals in the three areas was found to be at the average level, and the level of professional technical capacity was relatively low. In addition, the importance was evaluated that professional technology capacity is more important than the project development/evaluation capacity and communication capacity. Second, Second, in order to reinforce communication capacity, it is necessary to strengthen education on 'development of joint educational materials with colleagues'. Third, in order to reinforce project development/evaluation capacity, it is necessary to strengthen education on 'project planning'. In the IPA analysis results, the importance was high, but the capacity with relatively low performance were analyzed as 'project planning'. Fourth, in order to reinforce professional technical capacity, it is necessary to develop an education program for 'crop expertise' first. In the IPA analysis results, the importance was high, but the competencies with relatively low performance were analyzed as 'crop technology expertise'.

  • Recently China's science and technology development is accelerating, and some technologies have the world's best technology. With the rapid development of science and technology, China has been deeply aware of the importance of science and technology, and many efforts are being made to legislate security regulations to protect their technologies. Korea and other countries are also interested in research security, and research and development cooperation with China is also on the rise. In this paper, we derived some implications by comparing and analyzing China's science and technology security regulation and Korea's national R&D project management regulations. China is also enacting science and technology security regulations as a subordinate to the laws and regulations of science and technology. However, it should be reflected in future legislation that the difference from Korea is composed of separate independent regulations. In particular, the fact that the science and technology security regulations have been enacted separately may be a hint that can be reflected in the nation's future legislation processes. In this paper, major contents of the science and technology security regulations, points to division of knowledge property into scientific and technological cooperation or security tasks, designation of regulations on the characteristics of research security guidelines, and operation of individual national security agencies In addition, in the event that the contents of the related statutes, confidentiality provisions, and import and import control are recorded in this paper, and the results of the joint R&D project are not utilized, or the technology transfer is not carried out.

  • Economic transformations have led to an increase in the role of creative assets and their central role in public life. Changes in creative activity have led to a change in the organization of the work of institutes engaged in the training of specialists, in particular teachers of labor education. Methods and approaches to training determine the development of creative industries, being the basis for models of professional training of future teachers of labor training. The purpose of an article was to develop a modern model of professional training of future teachers of labor training based on the concept of creative economy. The methodology is based on the concepts of holistic craft and creative economy. Based on the integration of pedagogical learning models "Craft as design and problem-solving", "Craft as skill and knowledge building", "Craft as product-making" and "Craft as self-expression" developed and experimentally confirmed the conceptual model of professional training of future teachers of labor training. The proposed model forms a practitioner with professional, technical, digital and creative skills who is able to transfer the experience to students. The training course "Creativity and creative thinking" has been developed. The model provided for the development of a course based on the strategy of developing professional creativity, flexibility, improvisation, openness, student activity, joint practice, student-oriented approach. The practical value implies the adaptation of the developed model of professional training of future teachers of labor education during the training of teachers in higher education, which is confirmed in the experiment.
