  • In this study, localized heavy rainfall occurred during the collapse of steep slopes adjacent to the construction site and to ensure the safety of residents to build an early warning system was performed. Forecast/Alert range was estimated based on vulnerability landslide map and past disaster history. And established a critical line in consideration of the characteristics of local rainfall and operating a snake line, the study calculated causing and non-causing points. Also, be measured in real-time analysis of rainfall data in conjunction with the system before the steep slope failure occurred forecast/Alert System is presented.

  • Epidural steroid therapy has been well-established for the treatment of sciatica and low back pain. Disappointing results following surgical decompression or discectomy pain owing for to nerve root compression have led to trials of corticosteroids injected either systemically or into the intrathecal or epidural space to treat intervertebral disc. Epidural steroid is less effective in the patients with low back pain who have a history of surgical operation, so that the use of epidural morphine and methylprednisolone has been advocated for the amelioration of chronic low back pain in the post-laminectomy pain("failed back") syndrome over the past several years. We treated 47 patients with low back pain who had a history of one or two surgical procedures. We concluded that epidural steroid therapy is less effective in the patients with "failed back" syndrome than in the virgin back furthermore, there is a greater risk of complication such as inadvertent dural puncture and corresponding motor paralysis and headache.

  • This paper is to show the history and the brief present situation, the further vision and the considerations of Vojta physical therapy. Since Vojta therapy has been introduced into Korea in 1980, the workshop had the total 7 times and has produced 76 Vojta physical therapist during the past 15 year. But Vojta thrapist members have a gradually declining tendency in the present state. The counterplans for the considerations as follows; 1) Physician and Vojta therapist must be concerned about the growth of Vojta diagnosis and therapy. 2) As the medical examination and treatment system's establishment, an early infant's tretment will be performed. 3) The course of workshop in Korea must be admitted to be a regular qualification by the Vojta center of Germany. 4) Cerebral palsy treatment need home care system by Vojta therapist. 5) Vojta therapist has to reside in a public health center.

  • This interdisciplinary study explores G$\ddot{o}$del's hermeneutics of the relationship between relativity theory and idealistic philosophy in terms of time. For G$\ddot{o}$del, Einstein's contribution to the physical realization of idealistic philosophy would be remarkable. We start with a historical background around G$\ddot{o}$del's paper for Einstein(1949a). From the perspective of G$\ddot{o}$del's cosmology, the second part addresses the relative nature of time, and the next then investigates the rotating model of universes. G$\ddot{o}$del's own results show that the temporal conditions of relativity and idealistic philosophy are satisfiable in the mathematical model of rotating universes. Thus, it could be asserted to travel into any region of the past, present or future, and back again.

  • In the past decade, East Asian Research has received attention from researchers as well as in South Korea society-at-large. The broad category of East Asian Research includes various disciplinary fields, such as "history, economics, and politics; however, few studies have used quantitative analysis to explore its development. In this paper, we used network analysis to identify the disciplines and active research areas, focusing on productivity, collaboration patterns, and citation networks of East Asian Research in South Korea. For this study, 6,646 journal publications related with East Asian Research and indexed by KCI (Korean Citation Index) during the 10-year period of 2004-2013 were considered. Results show that East Asian Research was led during this period by sole-researchers, rather than interdisciplinary studies. Moreover, a co-institution network represents active institutions with a high degree and collaborative centrality. In terms of journal-journal citation networks, journals belonging to both "history" and "Korean literature" disciplines were dominant.

  • Cycle test for developed phase change material (PCM) is necessary in order to assess the variation of latent heat, which decreases with time by deterioration. T-history method and measurement using heat-flux meter are appropriate for the cycle test in a tube filled with PCM because they do not need an extraction of sample in measuring heat of fusion. In the present study, these methods were applied to a PCM having a melting point below a room temperature, different to the past studies for PCMs melting above a room temperature. As a result of experiment using pure water as specimen, we can obtained rea-sonable values for heat of fusion.

  • Mekuro-Kazoen BLDG. is a complex of office, hotel, and banquet halls, builted in 1991, Tokyo, Japan. This building suggest us various issues about the representation of traditionality in current architecture. We can find the possibility of representation of traditionality in large complex, in past, rarely applicated. Even in Japan, such trial in official building as New Office Building of Tokyo in Sinzuku shows a application only in the elevation plan. In Mekuro-Kazoen BLDG, the applications of traditionality are found not only in external appearance, but also in interior design. And the traditional Japanese gardens in front of building and in atrium enrich the traditionality And the modenity and traditionality in this building are represented simultaneously not deteriorating each other. The issue of representation of traditionality in architecture should be succeed not only in now but also in the future. The method of application need to be studied and improved. The fields of application also should be extended such as large complex buildings and future-oriented buildings.

  • Since the importance of seismic design is greater, dynamic analysis is more widely using than past. The input motion is one of the most important factors of dynamic analysis. However, in Korea input motions are selected from U.S. and Japan those are captured from large magnitude earthquakes without considering seismic environment or generated in frequency domain. In this research, the methodology for generating input motions those are considered seismic environment and design code is proposed. The seismic environment compatibility is considered by performing deaggregation and the design code compatibility is considered by time-domain artificial time history accelration generation method. The results shows that seismic environment and design code compatible input motions are successfully generated.

  • The registration of Dongeuibogam as UNESCO's Memory of world was not only a national triumph but also an internationally important event. This event got rid of the opinions that suggested Dongeuibogam was a medical system practiced only un the limited area of Korea and this event signified the restoration of Dongeuibogam's international and universal position. Therefore, ih is now our job to find Dongeuibogam's modern applications and restore its value. This study was carried out with the purpose of examining the significance of Dongeuibogam's registration as Memory of world from a medical history's point of view and finding its modern applications. The author discussed significance in three parts of Past Significance, Present Significance and Future Significance. As for modern applications, the author reviewed currently used applications and considered the possible ways to restore its original value as an alternative for future medical science.
