  • In a large scale of excavation for the foundation of large-sized structures and underground structures, a considerable amount of earth pressure can occur. Steel beams that have been used to form a temporary structure to support earth pressure may be less economical and less efficient in resisting the high earth pressure. To cope with this problem, PCT(Precast Concrete Truss) system has been devised and investigated both experimentally and analytically. A proper connection method between the concrete truss members was proposed to accommodate fast assembly and disassembly. Full-scale test of PCT system was performed to verify the load-carrying capacity of the PCT system including the connections. The test results were compared with those of structural analysis. The test specimen which corresponds to PCT strut attained the ultimate load without buckling, but the detail of connector members needs to be improved. It is expected that precast concrete truss members can be efficiently incorporated into a temporary structure for deep and large excavation by replacing conventional steel beams.

  • Modern and contemporary humanities and social sciences supported the freedom and abundance of people. Today, however, freedom and abundance do not support human dignity, and are not sustainable. Therefore, we must reflect again on the direction of today's life and civilization. As part of this project, this essay analyzes the modern and contemporary humanities and social sciences and examines the meaning of Korean traditional thoughts. The lines presented to us by Korean traditional thought can be summed up 'the Three Elements of the Universe(Heaven, Earth and Man)' and 'Perfect Harmony between the Soul and the Body' and 'true humanitarianism.' These lines can be a starting point to overcome the problems posed by the lines of freedom and abundance in two contexts : First, while the lines of freedom and abundance today were biased toward the elements of the Earth or the Body, the traditional Korean thoughts have been both elements of the Heaven and the Soul since the beginning, which can therefore serve as a true humanitarian. Second, the true humanitarian line is as much sustainable as it criticizes the uncontrolled freedom and abundance, and seeks the right moderation to become a man of dignity.

  • We report patterns of astronomical seeing at KSA SEMO (Korea Science Academy Space Earth and Man Observatory). Though the data of the seeing measured at the local observatory is essential in identifying the seeing of the observatory, systematic measurement of seeing has not been made in Pusan yet. For this reason, KSA SEMO adopted the Santa Barbara Instrument Group (SBIG) Seeing Monitor to constantly record the seeing. The seeing monitoring was done through an elaborate procedure involving direct CCD images in the focal plane which were subsequently analyzed for the full width at half maximum (FWHM) Gaussian widths. Based on the seeing monitoring for 8 months, we classified five patterns of the seeing at KSA SEMO: 'Sunset/Sunrise Effect', 'Extreme Fluctuation', 'Sudden Increment', 'Daily Variation' and 'Stable Condition'. Seeing was generally good from 1:00 am to 3:00 am than other times, and it was also better in Winter than in Summer.

  • This study was conducted to analyze the patterns associated with the short-term variability of CO$_2$ concentrations over 24-h scale within and across the Korean Peninsula. In the course of our study, we compared the data sets obtained from Moo-Ahn (MAN) station located in the far western coastal area of Korea with those determined from major background observatory stations around the world from the periods of Aug. 1995 to Dec. 1997. The mean CO$_2$ concentration of the MAN area for the whole study periods, when computed using the daily mean values, was found out to be 374.5${\pm}$6.6 ppm (N=884); seasonal mean values were found out to be 378${\pm}$5.2 (spring: N=181), 372${\pm}$10.2 (summer: N =210), 372${\pm}$7.2 (fall: N=243), and 376${\pm}$5.4 ppm (winter: N=206). When the data from MAN was compared with those of major background stations, the effects of both daily and seasonal components appear to vary distinctively across different stations. Those effects are expected to reflect the mixed effects of various factors which include: seasonal pollution patterns, weather conditions, vegetation, and so forth. Based upon this comparative analysis, we suspect that the MAN area is under the strong influence of anthropogenic source processes relative to all the other stations under consideration. If that is not the case, the existence of enhanced CO$_2$ level may be rather ubiquitous phenomena in Korea. More detailed inspection of CO$_2$ behavior from various respects is strongly desired in the future.

  • Keeping in step with four seasons, Spring, summer, autumn, and winter, the heaven and earth(天地) has been born(生), grown(長), coverted(化), gained(收), and kept(藏) by interaction of yiyang and yuqi(五氣: 木火土金水). And according to Naiching, human being is born with energy of heaven and earth(天地之氣) and is grown with the law of four seasons(四時之法). So, we now know that the human's body and nature interact each other. The oriental medical science has been studied the effect that the nature's change influences on human body. Now, I get some idea that using herb medicine and acupuncture should have hanged following the change of four seasons. We know that there is a cycle in nature. Every day sun arise and down, and every month moon gets full and new. And every year, four seasons orderly change, from spring to winter. All of this is the law of nature and human body adapts this law. Man always shows the physiological phenomena which changes under the law of nature, especially the turning of the seasons. Therefore, we should use different medical methods in different seasons.

Incarnation and Divine Essence in Daesoon Thought: A Comparative Study between Daesoon thought and Christianity

  • This article compares the concepts of divine incarnation as expounded in Daesoon Thought and in Christianity and questions the essence of the divinity in both traditions. In Daesoon Thought, The Supreme God, Sangje, saw major disorganization leading to extreme violence and doom and decided to incarnate on earth under the human form of Kang Jeungsan (1871-1909). Then the living God taught the solution to human suffering through the revelations he sent in 1917 to Jo Cheol-Je, or Jo Jeongsan (1895-1958) and the revelations were passed on to Dojeon Park Wudang who in 1969 founded Daesoon Thought. In Christianity, God incarnated in his son, Jesus Christ, who allowed for the radical transformation of the condition of man through his physical sacrifice. Daesoon differs in that Sangje did not offer himself as sacrifice when he came on earth but reorganized the world and taught how to apply benevolence to establish the Earthly Paradise. The affirmation that Daesoon Jinrihoe is both monotheistic and polytheistic is then analyzed. If the concept of monotheism seems to differ vastly between the two traditions, it appears that biblical monotheism is itself relatively young in the history of world religions so that Christianity has ancient roots germane to those of Daesoon Jinrihoe. The article concludes on the originality of this religion: though it is built on Daoism, Buddhism and Confucianism, it has transformed their vision of the deity and of its message in a most convincing manner.

  • Daesoonjinrihoe perceives that human suffering is caused not only by mental factors but also by the cosmic principle of Mutual Overcoming more fundamentally. The relationship influenced among all things in the universe is Mutual Beneficence and Mutual Overcoming. If these relations are properly cooperated in harmony, all things will reveal their energetic existence in a balanced state, however, if one side, particularly, Mutual Overcoming becomes excessive, indeed, it will cause trouble. That is, the sentient beings that are inclined to excessive Mutual Overcoming rather than indispensable Mutual Overcoming make grievances among themselves and cumulate them. In the end, heaven and earth lose its constant Way[常道], leading the sentient beings to all kinds of agonies. However, it may be a problem if every agony is depicted with Mutual Overcoming, that is, one single fixed frame, because Mutual Overcoming has to be interpreted diversely according to the circumstances. Thus, it is not possible to explain precisely about the agony if not understanding its spectrum. This study analyzed the ways how Daesoonjinrihoe explains the aspects of reasons and solutions to a variety of agonies. In the Supreme Scripture of Daesoonjinrihoe, the reasons for agony vary: first, it is caused by Mutual Overcoming of the cosmos itself, which is irrelevant to human beings. Secondly, man can be victimized because of Mutual Overcoming caused by man. Thirdly, there is a case of a victim who is damaged due to Mutual Overcoming caused by the other. Fourthly, man can be victimized because of Mutual Overcoming caused by someone else's unintended deeds. Fifthly, there is a case of man having agony in return when he, as a perpetrator, hurt others or resolve his inappropriate desires. Sixthly, man's deed unintendedly became a sin and have agony in return. Seventhly, man can be a self-perpetrator, conceiving vain desire, obsession and grievance. Eightly, there is a case of man having agony during enforcement of the law or practice of justice. Ninthly, man needs to endure agony during self-cultivation, enacting Reordering of the Universe(天地公事), ritual practice, promotion of fortune, and test. However, it is important to make sure that the reason for agony can interact with not only one but also diverse models in real situation. These nine models are included in the category of Mutual Overcoming; but, these cannot be classified in a single term, Mutual Overcoming because much information will be hidden, only to make it difficult to explain about agony more precisely. There are some characteristic observed in the concept of agony in Daesoonjinrihoe as follows: first, reasons for agony are caused by Mutual Overcoming although Mutual Overcoming can be interpreted differently according to the circumstances. Secondly, Daesoonjinrihoe makes a positive valuation for some agony. Thirdly, the solution to overcome a agony is brought to a conclusion, that is cultivation practice of Daesoonjinrihoe. Fourthly, the experience of agony and solution in Daesoonjinrihoe sometimes lie in the unit of family beyond individual. Fifthly, in the painful situation resulted from vain desire and obsession, Daesoonjinrihoe suggests a solution called Mutual Beneficence. That is, it emphasizes not only self-control but also active practice of considering others.
