  • The Literature Museum Network aims to realize the legislative purpose of the Literature Promotion Act and achieve balanced development of local literature centers across the country. In the Literature Museum Network, the literature museum network support center will be established by region to take charge of cooperation projects between local literature centers, which will be the culmination of the National Literature Museum of Korea. It is intended to test-run various projects planned by the Munhakwan Network Support Center to create derivative contents, or to establish a regional hub literature center in charge of education and other affairs of the literature museum's workforce. If the existing metropolitan administrative districts are used to form zones, the entire country can be organized into four zones. They include the Seoul-Gyeonggi Literature Museum Network (23 local literature centers), the Gangwon Chungcheong Literature Museum Network (32 local literature centers), the Yeongnam Literature Museum Network (30 local literature centers), and the Honam Jeju Literature Museum Network (22 local literature centers). One literature museum network support center will be established for each region and one local literature center will be selected as the hub literature center. The Literature Hall Network Support Center is in charge of collecting and managing literary materials, developing contents and programs, promoting and foreign cooperation, etc. The hub literature museum will be in charge of pilot operation of content and programs, training and education of experts in the literature museum, and running joint storage facilities. This structural system and efficient operation of the literature museum network will ultimately provide an opportunity for the formation of cultural governance in which the power and public nature of the establishment of literary promotion infrastructure are secured.

  • This study determined the effects of the height and the quality of the material of popular heel-up insole on mean plantar foot pressure during walking. Seven healthy college students who are studying at S university in Busan were as participants in this study. After sufficiently explaining about the research to the subjects before the experiment, mean plantar foot pressures were examined using F-Scan Pressure Measure System 5.23 for the gait with shoes inserted insole and the data were compared among the height and the quality of material of insoles. In the result, there was a difference significantly in the mean plantar foot pressure followed the height of insoles both left and right. Especially, mean plantar foot pressure in left indicated significantly lower in 3 cm and 5 cm insoles than in 0 cm and 1 cm insoles. Also mean plantar foot pressure in right showed significantly lower in 3 cm and 5 cm insoles than in 0 cm, and indicated significantly lower in 5 cm insoles than in 1 cm and 3 cm insoles. The mean plantar foot pressure followed the quality of the material of insoles were different significantly. In left, the mean plantar foot pressure of urethane poly-acetyl insole was lower significantly than urethane poly-acetyl inserted air insole, power-gel insole and jelly insole. And the mean plantar foot pressure of urethane poly-acetyl insole was lower significantly than power-gel insole and jelly insole in right. We showed that 3 cm and 5 cm insoles in the height of insoles and Urethane poly-acetyl insole in the quality of material were suitable to reduce a fatigue which is felt in plantar foot during the walking.

  • In Korea, nation and nationalism are undeniable justice, absolute virtue and moreover system of desire. From the late Chosun Dynasty when the Korean Peninsula had to survive from the critical situation of being the arena of competition, and through the colonial period under Japanese imperialism, nationalism became stronger as a logic of survival. The policy of seclusion under closed and exclusive nationalism that didn't recognize the world situation well enough, eventually gave more pain to the nation. Nationalism in colonial Korea which was as reformed nationalism and on the other hand, as intransigent, resisting nationalism. Since the purpose of this writing is not for clarifying the argument raised on Korean nationalism, there is no use mentioning how it went with the change of time. But we have to focus on the fact that the word 'nation' which appeared under the influence of popular revolution and capitalism meaning 'a group of people', was translated and understood as a racial concept for strengthening the unity of 'single-race nation with five thousand years' history. First of all, there is nationalism used to fortify the system. 'The Charter of National Education' and 'The Pledge of Allegiance' were ornaments to intensify the ruling ideology and dictatorship to militarize entire South Korea for 'settling Korean democracy' professed nationalism. Also, another ruling ideology armed with 'self-reliance' put North Korea into the state of hypnosis called nationalism. Nationalism, claiming 'nation' outwardly, but in reality, being an illuminating, instructing ideology isolating each other was indeed a body with two faces. This made 'nation' in Korea mysterious and objective through work such as. The statue commemorating patriotic forefathers' and picture of national records' in South Korea art. Nationalism used to strengthening the system encountered the magical 'single-race' and made 'ghost' being an extreme exclusion to other nations. We can find pedigreed pureness not allowing any mixed breeds from the attitude accepting western art -via Japan or directly- and making it vague by using the word Korean and Asia. There's nationalism as a resistant ideology to solidify the system on the other side. It came out as a way of survival among the Great Power and grew with the task of national liberation to became as a powerful force facing against the dictatorship dominating South Korea after the liberation. This discussion of nationalism as a resistance ideology was active in 1980s. In 1980, democracy movement against the dictatorship of 5th Republic originated from military power which came out suppressing the democratic movement in Gwangju, spread out from the intellects and the students to the labors, farmers and the civilians. It is well known that the 'Nation-People(Minjoong)'s Art Movement could come out under this social condition. Our attitude toward nationalism is still dual in this opening part of 21st century. On one hand, they are opposing to the ultra-nationalism but are not able to separate it from nationalism, and on the other, they have much confusion using it. In fact, in a single-race nation like Korea, the situation of being nationalism and jus sanguinis together can cause dual nationalism. Though nationalism is included in the globalization order, it is evidence that it's effective in Korea where there are still modern fetters like division and separation. In particular, in the world where Japan makes East Asia Coalition but exposed in front of nationalism, and China not being free from Sinocentrism, and American nationalism taking the world order, and Russia fortifying nationalism suppressing the minority race after the dissolution of socialism, Korean nationalism is at the point to find an alternative plan superior to the ruling and resisting ideology.

  • In order to improved treatment performance of dielectric barrier discharge (DBD) plasma, plasm + UV process and gas-liquid mixing method has been investigated. This study investigated the degradation of N, N-Dimethyl-4-nitrosoaniline (RNO, indicator of the generation of OH radical). The basic DBD plasma reactor of this study consisted of a plasma reactor (consist of quartz dielectric tube, titanium discharge (inner) and ground (outer) electrode), air and power supply system. Improvement of plasma reactor was done by the combined basic plasma reactor with the UV process, adapt of gas-liquid mixer. The effect of UV power of plasma + UV process (0~10 W), gas-liquid mixing existence and type of mixer, air flow rate (1~6 L/min), range of diffuser pore size (16~$160{\mu}m$), water circulation rate (2.8~9.4 L/min) and UV power of improved plasma + UV process (0~10 W) were evaluated. The experimental results showed that RNO degradation of optimum plasma + UV process was 7.36% higher than that of the basic plasma reactor. It was observed that the RNO decomposition of gas-liquid mixing method was higher than that of the plasma + UV process. Performance for RNO degradation with gas-liquid mixing method lie in: gas-liquid mixing type > pump type > basic reactor. RNO degradation of improved reactor which is adapted gas-liquid mixer of diffuser type showed increase of 17.42% removal efficiency. The optimum air flow rate, range of diffuser pore size and water circulation rate for the RNO degradation at improved reactor system were 4 L/min, 40~$100{\mu}m$ and 6.9 L/min, respectively. Synergistic effect of gas-liquid mixing plasma + UV process was found to be insignificant.

  • This paper describes the possibility of human physiological data, especially brain-wave activity, to detect cognitive overload, a phenomenon that may occur while learner uses an e-learning system. If it is found that cognitive overload to be detectable, providing appropriate feedback to learners may be possible. To illustrate the possibility, while engaging in cognitive activities, cognitive load levels were measured by EEG (electroencephalogram) to seek detection of cognitive overload. The task given to learner was a computerized listening and recall test designed to measure working memory capacity, and the test had four progressively increasing degrees of difficulty. Eight male, right-handed, university students were asked to answer 4 sets of tests and each test took from 61 seconds to 198 seconds. A correction ratio was then calculated and EEG results analyzed. The correction ratio of listening and recall tests were 84.5%, 90.6%, 62.5% and 56.3% respectively, and the degree of difficulty had statistical significance. The data highlighted learner cognitive overload on test level of 3 and 4, the higher level tests. Second, the SEF-95% value was greater on test3 and 4 than on tests 1 and 2 indicating that tests 3 and 4 imposed greater cognitive load on participants. Third, the relative power of EEG gamma wave rapidly increased on the 3rd and $4^{th}$ test, and signals from channel F3, F4, C4, F7, and F8 showed statistically significance. These five channels are surrounding the brain's Broca area, and from a brain mapping analysis it was found that F8, right-half of the brain area, was activated relative to the degree of difficulty. Lastly, cross relation analysis showed greater increasing in synchronization at test3 and $4^{th}$ at test1 and 2. From these findings, it is possible to measure brain cognitive load level and cognitive over load via brain activity, which may provide atimely feedback scheme for e-learning systems.

  • The basic magnetic properties of commercially available High-$T_c$ Superconductor (HTS) GdBCO-coated conductor (GdBCO-CCs) were investigated by using physical property measurement system-vibrating sample magnetometer (PPMS-VSM). From the zero-field-cooled (ZFC) m(T) curve, the $T_c$ was found to be ~93 K. After removing the background m(H) data, we obtained both the net m(H) data and the ${\Delta}m_{irr}$. The $H_{irr}(T)$ coincided very well with the power-law relation $H_{irr}=H_{irr}(0)(1-T/T_c)^n$ with $$n{\sim_=}1.19$$. The magnetic flux behavior was investigated by using the ${\delta}$ values in the relationship $J_c{\propto}{\Delta}m_{irr}{\propto}H^{-{\delta}}$. A ${\delta}{\approx}0$ region denoting an independent magnetic flux pinning effect, a ${\delta}{\approx}0.6{\sim}1.2$ region representing a collective flux pinning effect due to the interaction, and a ${\delta}{\gg}2$ region representing freely moving magnetic fluxes caused by the Lorentz force were observed. The boundary line between ${\delta}{\approx}0$ and ${\delta}{\approx}0.6{\sim}1.2$ is denoted by a $H_1$, and the one between ${\delta}{\approx}0.6{\sim}1.2$ and ${\delta}{\gg}2$ is denoted by a $H_2$. The ${\delta}(T)$ was obtained in the region of $H_1$ < H < $H_2$. As the temperature was decreased, the ${\delta}$ value gradually decreased.

  • This study was conducted on the assumption that bone age would be more effective when it comes to physique and physical fitness assessment for adolescents, and the purpose of this study was to identify the differences in physique and physical fitness for students in their adolescence through bone age and chronological age in order to contribute to the well-balanced physique and physical fitness development in adolescents and the health improvement in students. Total 874 adolescents(483 males, 391 females) aged 11~16 were selected as subjects out of the total population of 1100 adolescents aged 6~16 based on the PAPS(Physical Activity Promotion System) and age standards of the TW3 method; and skeletal maturation, which symbolize the indicators of biological maturation, were evaluated by using the TW3(Tanner-Whitehouse 3) method after hand-wrist radiographs, and birth date was used for chronological age. A stadiometer and InBody 270 (Biospace, Korea) were used to measure 2 components in physique. A total of 7 components in physical fitness, which included muscular strength, muscular endurance, flexibility, power, cardiovascular endurance, balance, agility, were measured as well. A independent samples t-test was conducted for data processing using SPSS 25.0, and the significance level was set at p< .05. The study results are as follows. First, bone age and chronological age used for physique comparison in males aged 11 and 12, height and weight showed significant difference; in males aged 13, weight showed signicant difference. Weight and height in females aged 11, and height in females aged 12 showed significant difference. Second, bone age and chronological age used for physical fitness comparison in males aged 11, muscular strength, power, flexibility, cardiovascular endurance showed significant difference; in males aged 12, muscular strength. power, cardiovascular endurance; in males aged 13, flexibility showed significant difference. Muscular strength, power, flexibility, muscular endurance, cardiovascular endurance in females aged 11, and flexibility in females aged 14 showed significant difference. As a result, this study concluded that in a period of rapid skeletal growth, evaluating physique and physical fitness based on bone age is more accurate than evaluating based on chronological age.

  • In this paper, we carried out the basic design of 36 MTD natural gas BOG re-liquefaction system to recover the generated natural gas during performance test of LNG pump and natural gas compressor. The re-liquefaction process of natural gas is designed to have 1500 kg/h of liquefaction rate with reverse Brayton refrigeration cycle. With the designed process, the variation of liquefaction rate is calculated for various inlet conditions of feed gas. From results, the liquefaction rate is more sensitive for inlet temperature than gas composition. The specifications of equipments such as gas blower, natural gas compressor, cryogenic heat exchanger and nitrogen compander are determined on the basis of the designed process. The requirement of power consumption and cooling water are also determined through the basic design.

  • There is a general agreement that the global social-economic system is undergoing fundamental changes, which can be explained in terms of the transformation of production system from the Fordism to Post-Fordism since the 1980s. These fundamental changes have resulted in the 'new urbanization' process in the most of large cities in the developed countries. The aim of this paper is to identify the 'new urbanization' process in a large city in Korea that is, Daejon. For the propose, this paper tries to examine and conceptualize empirically the changes of economic, political, social-cultural, and spatial aspects of Daejon metropolis in the respect of 'new urbanization'. The major findings of this essay are summarized as follows. First of all, Daejon economy has experienced new changes, that is the development of service economy and high tech industry. But the old industry still remain important in the urban economy. Secondly, in the political aspect, new civil movements flourish in the city, while the political power of Jaminlyeon, a pro-conservative and narrow-regionalism party, once dominated this region, has decreased its influence. Thirdly. the original CBD of Daejon has been declined while new (sub-)CBBs have emerging in Daejon spatial structures. In conclusion, we can find some clues of the new urbanization process in Daejon, but this process is still quite slow and somewhat different from those of large cities of the developed countries.

  • A Library is the fundamental character of culture in a country and it is also a barometer of culture in its community. Every cultural reality, however, can hardly come to fruition in a short time and so, it will be effected through a long time and tradition. This study aims at catching up how the above-mentioned public libraries have an influence on culture of its community people. For this purpose, the actual conditions of the public libraries have been investigated and analyzed and as a result of it, the problems have been reilluminated from the nation-wide point of view. And in the new changes, developing improvement measures have been tried to find. How to study was on the basis of the actual materials of the on the-spot survey, the interviews with the working officials and the response by way of questionnaire. Summing up the investigated and analyzed contents are as followings. In the above mentioned province, therefore, number of the public libraries are very limited compared with number of the people. And so, it is very essential to increase the public libraries in the province. In terms of the actual conditions, the public libraries lags far behind the other provinces in Korea from this library field. The present chronic conditions are the budgetary deficit, the collections insufficient to the legal minimal standards, the lack of professional librarians ignorance of the people and library managements by unprofessionals, etc.. This hinders the progress of the public libraries and to seculate them from the people. The improvements and the solutions to the above-mentioned problems are as follows. 1. To recruit the personnel sufficient to the legal standards and to reorganize the offices and to turn upward the highest class of librarian's position above the 4th class. 2. To secure collections sufficient to the legal standards and to strang then the extension services. 3. To organize the council composed of the chief librarians of the public libraries including the working chiefs in the province and to develop the works-in-hand of the libraries from the level of decision-making. 4. To organize the librarian training group and to study the working problems and to seek the qualified improvement of librarians. 5. The management of the public libraries in the province are, at present, der the Ministry of Education and the local government takes the financial power. So both should be shortly unified. 6. To do regularly the course of how to use library materials for the community people and to seek the inducement measures for the people through the various cultural events. 7. The public libraries organize the mutual cooperation networks and to seek the system automatized plans of free use of library materials and every library works. 8. To enlarge book mobile system actively and to infiltrate into the daily living of people deeply. Finally, what the present writer would like to speak to the chief librarians of the public libraries the human aspects of librarians should not be ignored no mater how excellent a library organization may be. In addition to this, the present writter is sure that the far-reached future of our library organization will depend on the librarians.
