The colony education policy of Japanese Empire was, as a su n.0, ppression on national salvation education of Korean, on the one hand it was liquidation of Korean national spirit and other hand, it has the object to Japanizing Koreans through cramming Japanese language and its culture. During the Japanse occupation of Korea, the libraries had two roles, one was to press Korean and its culture and the other was to civilize Koreans for Japanizing. The purpose of this study is to examine the role of rural-mini libraries whether the former or the latter. From 1932 to The Chosun Governor- General Department (Chosun Chongdokboo) actively spread 'The Movement of Rural Development in Korea. At the same time there were many rural -mini libraries in Korean rural and fishing community. Under the colony of Japanese Empire, colony policy was itself very tough that Japanese Empire did their utmost ideas to win Korean culture over and Japanzing Korean with every possible pressures. Since rural-mini libraries were planned by the chosun Governor-General Department, however, were established by Korean themselves with the property of local education center( Hyanggyo). Therefore, rural-mini libraries were as facilities to promote rural economic development for providing Japanese with some materials which need to conduct a war, and to introduce local people to participate in civilizing activity themselves and farmers and fishermen were forced to group to be educated in Japanese language and its reading. Rural-mini libraries were, as it were, not as facilities for enlightening Korean peoples but as facilities for civilizing Koreans.

The ZigBee network has been considered to monitor electricity usage of home appliances in the smart grid network. ZigBee, however, may suffer from a coexistence problem with wireless local area network (WLAN). In this paper, to resolve the coexistence problem between ZigBee network and WLAN, we propose a new protocol constructing a cognitive smart grid network for supporting monitoring of home appliances. In the proposed protocol, home appliances first estimates the transmission timing and channel information of WLAN by reading request to send/clear to send (RTS/CTS) frames of WLAN. Next, based on the estimated information, home appliances transmit a data at the same time as WLAN transmission. To manage the interference between WLAN and smart grid network, we propose a cognitive beamforming algorithm. The beamforming algorithm is designed to guaranteeing zero interference to WLAN while satisfying a required rate for smart metering. We also propose an energy efficient rate adaptation algorithm. By slowing down the transmission rate while satisfying an imperceptible impact of quality of service (QoS) of the receiver, the home appliance can significantly save transmit power. Numerical results show that the proposed multiple antenna technique provides reliable communications for smart metering with reduced power comparing to the simple transmission technique.

This study comprehensively draws a conclusion using factors of economic, social, and educational value and performed a survey on librarians and users to compare and analyze the difference in perception between the two groups. The result are as follows: First, Libraries had the social value not only on research and personal learning but also on establishment and vitalization of communities, provision of opportunities to share ideas between local residents and create something new, and provision of recreation to improve the residents' capability. Second, both groups evaluated the libraries' educational role and function relatively highly. In particular, the librarians scored very high for the items that the libraries' educational role was expanding, the libraries were a part of the educational system, and the libraries' value on reading and literacy was great, and the users thought that libraries had an value because they were a part of education and the educational system. Third, economic value part also obtained relatively lower scores than other values; the mean of the librarian group was 3.46 and the user group was 3.43. Among the economic values, the librarian group scored the highest for the area of economic value for local communities, and the greatest scores were given to manpower development by the users.

Purpose - Drawing upon signaling and social identity theories, this study explores the effect of engagement in CSR activities by foreign firms on applicants' intention to apply. Furthermore, this study suggests CSR education as a moderator which strengthens the positive effects of the engagement in CSR activities on the intention to apply for potential job seekers. Research design, data, and methodology - One hundred and ninety-one undergraduate students were solicited to participate in this study. Participants were randomly assigned to two scenarios depicting different levels of a given foreign firm's engagement in CSR activities. After reading the given scenario, respondents answered a series of questions on their intention to apply to the foreign organization. Result - The results from hierarchical regression reveal that Korean applicants have a more favorable perception of a foreign firm which performs engagement in positive CSR activities. Moreover, the positive effect of the engagement in CSR activities on the intention to apply has a greater impact for Korean applicants who had CSR education. Conclusion - The result indicates that foreign firms could overcome the liabilities of foreignness and attract local talent effectively, by engaging in CSR activities. Moreover, this study suggests the important role of CSR education, and significantly contributes to the international recruiting literature.

This study analyzes the processes and the needs of public library services for multicultural populations based on cooperation between public libraries and local organizations. In-depth interviews with public librarians and officers of local organizations were conducted for this case study. Result shows that cooperation was inevitable because there was not enough library personnel compared to the amount of services they have to provide, and the librarians did not have proper skills to serve the diverse populations. Public libraries were cooperating with many local organizations including the Multicultural Family Support Center. Gatekeepers of ethnic communities were playing important roles in promoting and inviting participants for library programs. Many children and young adults with immigration background gained positive views on reading and libraries after participating library programs based on cooperation between public libraries and local organizations, which was recognized as the best achievement of cooperation by many interviewees. Despite many good results of cooperation, how to get to the majority of diverse populations who are not library users yet is still a question mark. Interviewees for this study all agreed that current library service has limitations and insisted a whole new method to invite immigrants and their families to public libraries should be created.

Objectives: The aim of this study is to evaluate exposure levels of the extremely low frequency magnetic fields(ELF-MF) radiated from various electric facilities in Liquid Crystal Display(LCD) manufacturing processes. Methods: This study measured the exposure levels of personal and local ELF-MF for the electronic facilities installed in two LCD manufacturing companies. Samplers were installed around workers' waist during working hours to identify personal exposure levels, and direct reading equipment were located at 3 cm, 10 cm, and 30 cm away from the surface of the electronic facilities to measure local exposure levels. Average and maximum(ceiling) values were calculated for personal and local exposure levels. Results: Average and maximum of personal exposure levels for each worker were 0.56(mean) ± 0.02(SE) µT and 6.31 ± 0.75 µT, respectively. Statistical analyses of the study found that maximum of the personal exposure levels for engineers was significantly higher than that for operators since engineers spend more time near the electronic facilities for repairing. The range of maximum personal exposure levels was 0.50 ~ 43.50 µT and its highest level was equivalent to 4.35 % of ACGIH(American Conference of Governmental Industrial Hygienists) exposure limit value(1 mT). Maximum of local exposure levels was 8.18 ± 0.52 µT and the electronic facilities with higher exposure levels were roof rail and electric panel, which were not related to direct manufacturing. The range of maximum local exposure levels was 0.60 ~ 287.20 µT and its highest level was equivalent to 28.7 % of the ACGIH exposure limit value. Lastly, the local exposure levels significantly decreased as the measurement distance from the electronic facilities increased. Conclusions: Maximum of personal and local exposure levels did not exceed the exposure limit value of ACGIH. However, it is recommended to keep the workers as far as possible from the sources of ELF-MF.

We demonstrate a high-speed recording based on field-induced manipulation in combination with an optical reading of recorded bits on Au cluster films using the atomic force microscope (AFM) and the near-field scanning optical microscope (NSOM). We reproduced 50 nm-sized mounds by applying short electrical pulses to conducting tips in a non-contact mode as a writing process. The recorded marks were then optically read using bent fiber probes in a transmission mode. A strong enhancement of light transmission is attributed to the local surface plasmon excitation on the protruded dots.

The library of elementary schools, which plays a role in the basic education to grow a responsible social member in an information society and to develop ability for collection, selection, summary, and utilization of various information, could be considered as new educational center. It should be changed to the establishment of informational education for preparing the information society in 21st century through the functional extension of the conventional library as reading and bookstand. Furthermore, it is necessary of trials that converts to the support system for interchange between establishment and student, for preparing educational system of teaching or studying, and for opening establishment to local communities in the future.

In the velocimeter, the ultrasonic pulse signal is used for measuring the profile velocity of moving targets distributed in space because of the merits of its high distance resolution and harmless affect to the human body. The velocity reading in conventional ultrasonic pulsed velocimeter depends on the wave pattern reflecting the spatial distribution of scatters and includes observational error due to the signal processing of analyzing pulse signal. In this paper, we evaluate an influence of the received waveform of pulsed signal on the velocity information by setting a model. Subsequently, in order to improve the distance resolution and to obtain precise velocity information without the influence of the spatial distribution of scatterers, we propose a new method for the analysis of Doppler pulsed signal, in which the pulsed signal is transformed into a phase function with local data. Finally, it is confirmed that the performance of the velocimeter is more improved in the proposed method than in the conventional one.
