In the context of accelerating the establishment of specialized libraries, this study aims to reestablish the entire system of specialized libraries scattered by Gimpo City as the Gimpo City Library has been in operation for 20 years. It aims to establish a specialized vision and strategy. In this study, the operational problems of the Gimpo library were discussed from three perspectives. First, there is a problem in selecting a special theme. Next is the problem of using specialized materials. Lastly, it is a matter of not operating the actual specialized program. Based on this analysis, three directions for the development of specialized topics were proposed. First, the selection of specialized topics based on local content and user needs. Second, it is necessary to prepare a plan to activate specialized services. Third, local specialty networks should be strengthened.

In this paper, a method is proposed for establishing an approximate prediction model of rotor-dynamics through modal testing. In particular, the proposed method is applicable to systems that cannot be established according to conventional methods owing to the absence of information regarding the dimensions and material of the rotor-bearing system. The proposed method is demonstrated by employing a motor dynamometer driven by a 1 MW class induction motor without dimension and material information. The proposed method comprises a total of seven steps, wherein an initial model is established by incorporating approximate dimensions and material information, and the model is improved on the basis of the natural frequency characteristics of the system. During model improvement, the modification factor is introduced for adjusting the elastic modulus and shear modulus of the system. Analysis of critical speed and imbalance response indicates that the separation margin is 67% and the maximum vibration amplitude is less than the amplitude limit of 0.032 mm under the API 611 standard, which means that the motor dynamometer can stably operate at a rated speed of 1800 rpm. Hence, the obtained results validate the feasibility of the proposed method. Furthermore, for broad usage, it is necessary to accordingly apply and validate the proposed method for various rotor-bearing systems.

In order to investigate the meanings and bases of transforming theories of diseases(病傳論), several relevant theories were collected from medical books since . The outside-to-inside changing process(pyoree jeon) was the fundamental pattern in febrile diseases regardless of slang han and wen bing after Han dynasty. But in case of numb disease the three exogenous pathogenic factors of wind, cold and dampness got into each viscera through five tissues like skin, vessesl, flesh, tendons, bones respectively. It was called corresponding changing process(sanghap jeon) here. The pathogenic changing process(byungsa jeon) had complicated details to explain pathologic processes, but could give useful informations on evaluating relative strength of pathogens and tendency ahead. The changing process of diseases of internal injuries were explained in case of emotional distress which is outbroken abruptly didn't follow regular order of viscera-emotion relations. So it was named random changing process(bulcha jeon) after 's usage. And marasmus and asthenic disease followed top-to-down or down-to-top changing process(sangha jeon) based on . There are many types of changing process of diseases between viscera and viscera or viscera and bowels like generation changing process, restriction changing process, changing process between couple, changing process of mutual transmission based on attributions of each element by the theory of 5 phases(五行論). And changing process to a neighbor doesn't have any special relations within two organs but has anatomical contiguity and physiological continuity between them. The transforming theories of diseases bring forth useful understanding on comings and goings of pathogenic factors and tendency and prognosis of disease, so they are needed to be taught in the course of pathology class.

In an effort to apply IT to practices of learning, universities are trying to implement e-Learning systems and expanding the extent of their usage. Nowadays, e-Learning systems are not only used for conducting web-based distance learning, but also used for supporting traditional classes education by encouraging communication and information sharing between instructors and learners or among the learners. There is relatively lack of studies on the exploitation of e-Learning systems in the traditional classes, in comparison with a distance education. Specifically, howe-Learning systems could support the traditional class and/or which benefits e-Learning systems could offer in the classes are among the important issues. In this study, we suggest that e-Learning systems would be the rich media to communicate and exchange information among people who participate in a class. We derive key variables like media richness and media experience from Media Richness Theory and from Channel Expansion Theory. Moreover, Media usefulness and Satisfaction of a learner with e-Learning system is drawn from the literature on IS success. We examine the effects of perceived media richness, media usefulness, and media experience on leaner's satisfaction with e-Learning systems. In addition, we also investigate learner's media usefulness perception which is positively related to media richness and media experience. Finally, learner's experience with e-Learning systems affects perceived media richness. Based on the results of an empirical test. we first suggest that perceived media richness with e-Learning systems contributes to increase media usefulness and satisfaction of a learner. Second, media experience is an important predictor of media richness and media usefulness perception. Consequently, the result can support Channel Expansion Theory. Finally, media usefulness perception affects learner's satisfaction with e-Learning systems.

As the issues such as safety, hygiene, convenience of school facility from the perspective of living environment for students and teachers arise as an important task in recent, there is increasing concern for resting convenience facility in school. In recent, the government is planning to change middle high school into the departmental classroom system. The departmental classroom system refers to the school operation system in which the classroom is structured as a subject-specialized classroom and the students move to the classroom according to their class schedules. This departmental classroom system is advantageous in that each subject can be equipped with professional facilities or preparations; the usage rate of the classroom can be enhanced; the common study space or living space can be used substantially; the school can plan and operate its own specialized space. On the contrary, it has the weaknesses that there is need to prepare the home base for the guidance of the class or student guidance; there is need for the facilities including personal lockers. Thus, the departmental classroom system requires the space expansion for home base or the resting convenience space for students and thus has to provide various spaces. Under this background, it is also important to check and plan the resting space for the schools. Therefore, this study is aimed to examine and analyze the arrangement location and space Layout of the resting convenience space among school facilities to propose the architectural data for future resting/convenience spaces for the schools.

Usually piston or rotary engines are installed at UAV's under 100 kg payload class. Those engine are less expensive and easy to get, but they require higher operating and maintenance costs due to shorter life and unique fuel usage. They are also too noisy to operate in urban area and have too strong vibration to carry sophisticated payloads. On the contrary, a gas turbine engine has drawbacks like higher specific fuel consumption and weight to power ratio, even it has many operating and maintenance benefits. This study aims to design a small turboshaft engine with a recuperator to overcome those demerits. A tilt rotor UAV(TR-60) developed by KARI was chosen as an imaginary target aircraft, and engine power and size were derived from it. This paper describes engine requirements, design process, and initial reference point cycle design.

Based on the recent consensus on the need for software education, software education has become mandatory in universities in Korea. However, the suitability of class contents and the relationship between class contents and learner satisfaction has not been fully discussed. Therefore, in this paper, we analyzed the suitability of the contents used in the basic software education for the humanities students from the learner's perspective. For this purpose, three types of curriculum, which are 'computer science', 'usage of tools, and humanities in the digital world' and 'computational thinking', were compared using the lecture assessment questionnaire. As a result, we found that the learners evaluated positively over the curriculum that focused on the use of tools, the humanities approach, or the thinking ability rather than the theoretical contents of computer science. We also found that the subjects related to computer science could not give high satisfaction due to their unfamiliarity, relatively low academic value was given to the tool-centered curriculum, and fatigue was expressed in discussion-based thinking ability education.

Due to the aging population and the entry of baby boomers into the elderly, the elderly are recognized as a group with diversity rather than a single group with the same needs. Therefore, it is necessary to try to grasp the factors that the elderly use welfare centers from the perspective of consumers. The results showed that gender, age, education, occupation, economic status, social class, number of friends, number of social activities, number of diseases, and depression were significant. In other words, women than men, older people, highly educated people, elderly people without jobs, elderly people with poor economic status, the elderly belonging to a lower social class, the more friends, the more social activities involved, the more diseases, the higher the depression, the higher the probability of using the welfare center. It was found that heterogeneous elderly groups, such as the elderly with high educational background, many friends, and active participation in society, and the elderly, economically difficult, and poor in health, use the welfare center. Based on these research results, policy and practical suggestions were made to improve the quality of welfare services for the elderly.
