The present study was motivated by the needs to make diversified scientific approaches toward influential factors like human, technical, organization, policy and environmental on the basis of the specialized information concerning the cause for industrial accidents in a measure to prevent the falling accident which has the biggest priority among the three major frequent industrial accidents. In this connection, diverse policies have been practiced in the meantime, with little effects in fact to reduce occurrence of industrial accidents, seemingly because such policies have been practiced on the direct dimension, instead of tries to nip in the bud of fundamental causes. This study was thus conducted with a view to determine the causes that have influence on falling accidents from the overall context and unearth the factors requiring management with priority. For this aim, "Fall from Height"(2003), a study by HSE, UK was applied to various conditions of korea as an experiment to search for fundamental causes for falling accidents. The major findings of this study might be summed up as exploring a main critical path that has influence upon falling accidents and suggesting effective ways to cut down through the critical path.

The ROK military conluded that the dead of a young soldier, walking back to his unit was caused by a ricochet after carrying our some construction work near firing range in Gangwon Province in last Septemebr. But when it was revealed that he was hit by a stray bullet cause, this fact caused public fury. To solve these problems, we will analyze the individual fire shooting range of our military units from a safe perspective and propose ways to improve it by applying the cases of the United States, which are both permanent and scientific.

Goryeong Jeesandong tombs No.73 from the 5th century located in Gyeongsangbookdo is the most representative remains of the Daegaya. They were excavated and examined by the Daedong Research Center for Cultural Properties. In this study, the textiles in the Goryeong Jeesandong tomb No.73 is identified and their features are examined through scientific analysis. Due to the fact that the remains were not treated for preservation, we were able to observe many samples under the microscope. Within the hemp textiles both hemp and ramie were made using s-twist threads and the thread count distribution is calculated to be 8.0${\sim}$20.0/$cm^2$. Among the silk, the taffeta was categorized into five types. First, there was plain woven silk which the thickness of the warp and the weft is the same and their rate of threadcount was the same. The second type was thin tabby which is spacious between threads. The third kind was woven by warp and weft which had very different thickness. The fourth type used two threads for each warp. The fifth kind used two threads for the warp threads and used thick threads for the weft for a modified plain weave, and it is the first of its kind to be found. Also, there was a compound weave with warp-faced compound weave among silk.

Near-infrared spectroscopy (NIRS) is potentially a powerful and revolutionary technology for environmental analysis. It is supported by a large body of scientific and experiential knowledge. The instrumentation is well-developed, with easy-to-use, highly dependable instruments, but at the same time it is still developing, particularly with the production of more portable and rapid instruments, and more powerful software. NIRS is used globally in numerous industries for commodity analysis. Yet NIRS is largely unknown in the field of environmental chemistry and monitoring, and is not even routinely used in soil analysis, where the research literature on NIRS extends over four decades. Part of the explanation for the poor visibility of NIRS is the fact that NIRS is not routinely taught in Chemistry programs in universities, where most environmental chemists and environmental technicians are trained. This presentation examines the unique capabilities of NIRS, such as rapid, real-time analysis; analysis of whole samples; simultaneous analysis of multiple constituents; cost-effectiveness, and portability, as they match needs for analysis in several environmental areas. Examples of NIRS usage and published and unpublished results will be described for such areas as soil and sediment analysis; water quality monitoring; and nutrient loading in application of manures and sewage sludge (biosolids) to land. Present barriers to the use of NIRS in environmental analysis will be discussed. It is argued that emerging environmental problems and increasing attention to some traditional problems will enhance the application of NIRS in the future.

Korean tremoitic talc, wollastonite and clay have been used to develop a wall tile body to appropriate to the fast firing process. Some of ceramic properties of the raw materials were investigated by X-ray diffraction, thermal analysis and chemical analysis. The body compositions were formulated from the range of 35~75% tremolitic talc, 0~30% wollastonite and 25~35% plastic clay. Thermal gravity analysis and thermal expansion were tested for each of unfired bodies to study the correlation between thermal dehydration and linear shrinkage during the firing procedure. Linear shrinkage and water absorption of the fired bodies at the various temperature were taken as a measures for determining the proper firing range of the bodies. Increasing the content of wollastonite and firing temperature, the thermal expansion of the fired body showed the gradual decrease, and the thermal expansion curves showed a tendency to straighten. These observations may be resulted from the fact that the amounts of diopside and anorthite formed were gradually increased and those of quartz relatively decreased. The optimum compositions of the wall tile bodies for fast firing are 30% clay, 10~20% wollastonite and 50~60% tremolitic talc.

This study clarified the fact that the existing 'manpower supply and demand plans', preceding studies, theoretical researches of the past cannot satisfy the multi-goals of organizations, instead, the existing plans focused on only the number of customers and total amount of service. Next, a necessity of more proper manpower plans that consider comprehensive goals of the organizations is suggested then, this study tried to make the countermeasures. As for studying methods, a priority sequence in the organizations' manpower management's goals is set by AHP(Analytic Hierarchy Process), a business administrative scientific skill. Proper manpower policies of the food service enterprises, which satisfy the organizations' multi-goals, are established by GP(Goal Programming). Based on it, mid and short term 'manpower supply and demand plans' are established. For the purpose of increasing the study's efficiency, example studies are conducted in one family restaurant. The limit of this study is that inner personnel management details such as promotion, new personnel appointments, unemployment, retirement were not considerately considered. Therefore, the future studies should think over those limits and research the labor-force supply from the outside also.

Conventional full-text information retrieval system has been proved with high recall ratio and low precision ratio. One of the disadvantages of full-text IR system is that it is not designed to reflect the user's information need. It is due to the fact that full-text IR system has been designed based on physical and logical structure of document without considering the content of document. The purpose of the study is to develop more effective full-text IR system by resolving such disadvantages of conventional system. The study has developed new method of designing full-text IR system by using Content Structure Markup Language(CSML) other than conventioanal SGML.

Nanotechnology is an emerging field with many promising applications in drug delivery systems. Because of outstanding developments in this field, rapidly increasing research is directed to the development of nanocarriers that may enhance the availability of drugs to the target sites. Substantial fraction of information has been added into the existing scientific literature focusing on the fact that nanoparticles usually generate reactive oxygen species to a greater extent than micro-sized particles. It is worth mentioning that oxidative stress regulates an array of cell signaling cascades that resulted in cancer cell damage. Accumulating experimental evidence over the years has shown that wide-ranging biological mechanisms are triggered by these NPs in cultured cells due to the unique properties of engineered nanoparticles. In this review, we have attempted to provide an overview of the signaling cascades that are activated by oxidative stress in cancer cells in response to different kinds of nanomaterials, including quantum dots, metallic and polymeric nanoparticles.

Every field of studies form its theory through its universal method and own method based on respective views with its own culture and contributes to academic advancement with appropriate research methodology within theory. Therefore, If methology of oriental medicine is not include universal method and particularity method in research methology, it will not obtain scientific character and lose its logic. The methology of oriental medicine is classified by two approaches, universal methology of natural science which inspect the effect through experimentation on the fact, and particularity methology of human science which understand the effect through translation on the value(politics, economics, society, philosophy, history and culture). In this paper, the methodology of oriental medicine contains duality including both universality and particularity.
