Samhwajahyangyakbang, a medical book of Hyangyak which was presumed to be published by Samhwaja in the late Goryeo dynasty, became the original source of Hyangyakganibang. As Hyangyakganibang became the original source of Hyangyakjesengjipseongbang which was supplemented to be Hyangyakjipseongbang, Samhwajahyangyakbang is a fundamental book which is the original source of Hyangyak medical books such as Hyangyakganibang and Hyangyakjipseongbang in the late Goryeo and the early Chosun dynasty. I restored the articles of Samhwajahyangyakbang, mainly focusing on the remaining articles in Hyangyakjipseongbang, followed by supplementing some other remaining articles with the help of , a database of old medical books, and then, recorded and discussed the results in the paper. 1. The remaining articles of Samhwajahyangyakbang were found in Hyangyakjipseongbang, Uibo and Uibanghappyeon. Among them, there is a prescription which is not overlapped in Uibanghappyeon. 2. The classification system of Hyangyakjipseongbang was alternatively adopted due to the absence of classification or table of contents in Samhwajahyangyakbang. 3. There are a total number of 152 articles in the restored Samhwajahyangyakbang and 151 articles out of the total number have been restored from Hyangyakjipseongbang. There are 5 articles which remain as notes in the citations of other books in Hyangyakjipseongbang. 4. There are a total number of 246 prescriptions in the restored Samhwajahyangyakbang. 5. Even though Samhwajahyangyakbang is a concise medical book, it is one of the core medical books which are cited in Hyangyakjipseongbang. In addition, it is the most frequently cited in Hyangyakjipseongbang among the Korean medical books. It implies that the compilers of Hyangyakjipseongbang considered Samhwajahyangyakbang the most valuable book among the Hyangyak medical books. It is speculated that such results could be achieved because Samhwajahyangyakbang was very popular in those days and its' printing quality was also good. On the contrary, the number of citations of Hyangyakgugeupbang is much less than that of Samhwajahyangyakbang. It is presumed that Hyangyakgugeupbang could not be distributed widely not because it was less valuable but because its' printing quality was poor.

This study aims to investigate the impact of wide use of digital technology, in particular, the Internet, on innovation process and corporate strategy in electronics industry. The introduction of digital technology has changed innovation process, business model and organizational structure of the electronics companies. With the introduction of digital technology, the entire value chain of electronics industry from procurement, sales, and marketing to R&D and manufacturing has been restructured. E-commerce has been a major agenda for e-business. Recently, collaboration among electronics companies through e-marketplace has emerged as an important issue. A web-based e-commerce standard, so called RosettaNet, has been developed for facilitating e-transactions of electronics firms. The development of digital technology has dramatically increased the processing speed and sophisticated the virtual reality technology. As simulation becomes easier and more effective, the uncertainty and risk involved in R&D has decreased significantly. Another positive impact is closer cooperation between R&D and manufacturing functions. Taking advantage of automated and flexible production technology, has a new type of firm, so called, EMS (Electronics Manufacturing Services) emerged, whose strategic focus is on manufacturing only. The EMS can be seen as a kind of innovative organization, that is, a modular organization for production function. Digital technology has made convergence of computer and communication possible at early years but right now the convergence has been accelerated in extensive areas of communication, broadcasting, information appliances, software, contents, and services. Firms' effort for an innovative product and service has been intensified and the competition for a new standard product and service has become severe in electronics industry. Business activities are always realized in a specific organizational context. Accordingly building up innovation-friendly organization has emerged as a critical concern. Due to the striking decrease of transaction cost, a network type of organization has proliferated, and a business function turns into a modular organization. As a whole, digital technology has pushed electronics firms into developing their own business model, which takes consideration of standardization of business platform and their core competency.

The present water quality standards for agricultural were established without considering the effects of water quality on the safety, growth, yield and quality of crops. This study was carried out to investigate the effects of irrigation water quality on the growth, yield, and grain quality of rice, and to acquire basic knowledges to set up water quality standards for irrigation. The field and pot experiments were conducted with irrigation water that was previously adjusted four concentrations (control, 5, 10, 20 mg/L) and six concentrations (control, 5, 10, 15, 20, 30 mg/L) by $NH_4NO_3$ solution and replicated three and four times with randomized block design, respectively. The results of this study showed that the inorganic nutrient of rice plant, rice protein contents and number of panicle tended to increase as the T-N concentration in irrigation water was increased. In addition, grain yield at T-N 10 mg/L and 20mg/L were significantly higher than the control at the field experiment. From the pot experiment at T-N 30 mg/L, the percentage of head rice was slightly lower due to the increase of green kernel and white belly/core kernel.

The information system fields of spatial applications have rapidly grown during the last decade in Korea. Spatial data has been produced for a variety of systems without common standards until national GIS Committee defined the data exchange formats among spatial databases in the middle of 1990's. It aimed at promoting data sharing between the different systems in similar application fields. However, a considerable number of databases built prior to the introduction of the standards are not yet standard compliant but still play the roles of the main producers/consumers in the data collection field such as early developed huge AM/FM systems maintained by governmental organizations. The strong autonomy of these databases keeps their own data models, formats and descriptions from being standardized, which leads the sharing to a more difficult stage. Sharing is another way of data acquisition with least efforts and time away from direct collection. A data clearinghouse is the core module which directs users to the relevant data resources. The contents of datasets should be described with predefined metadata standards for precise indexing. Moreover, a number of technical problems have to be resolved for the common use of data between heterogeneous spatial database systems. However, the technical issues can be covered by the present information technologies. The difficulties persist in the political/institutional issues. Institutional issues are derived from the diverse sources such as political background, governmental policies, related laws and/or regulations. The paper will firstly make an analysis of current situation in terms of Korean policies, laws and regulations, secondly abstract the institutional issues from the situation analysis, lastly present guidelines for promoting spatial data sharing in Korea.

The purpose of this study is for considering about Zen fashion in the point of view of culture transition. Through this research, the Far-East including Korea will be confirmed as a center of fashion culture in 21st century. The contents are the meaning of culture transition in Post Modern period, the meaning of Zen and changing of fashion trend as the background of Zen Fashion, and the characteristics of Zen fashion design. The results are as follows: Anti-western movement or dismantlement of culture has been represented the limitation of western centered culture. So the interesting about East means the changing to east from west in ideas. To make new creation in fashion field, the comprehension about the western fashion which has been preceeded and new trials using the our tradition will be needed. Zen is a kind of Buddhism and the essence of it is to find myself and express individual experiences. The change of one's sens of value, new age movement and concerning of environment and ecology make more comfortable, simple and healthy elements in clothing. The fusion style is under a vogue in life style and Zen is the core of this trend. The characteristics of Zen fashion are flat dismantlement which has been know as a Japanese style, oriental minimalism and nature beauty of ecology. This characteristics are found not only the shape, color but the will of the behind. The pursing temperance and naturalism are represented the fashion culture transition from the West to Far-East. Therefore multi points of fashion research is very important and the identify about Korean fashion is required in lately for new fashion paradigm.

Electronic commerce creates serious problems for tax administration because of difficulties associated with the identification of traders, coding of trade activities and so on. The core issue with respect to resolving tax-related problems in electronic commerce is first, the identification of individual transactions through internet and their contents as well as traders. Secondly, it is the ability of tax authorities to secure effectively such data and information as identifying taxpayers, taxable amount and tax evasion on time. The tax authorities are studying the way to resolve tax evasion associated with electronic commerce by using payment system. Above of all, it is imperative to establish a systematic international cooperation in collecting value added taxes for electronic commerce. In order to enhance the effectiveness of tax system, the authorities of different nations should make joint efforts to collect taxes by exchanging such information as identification and registration of business as well as details of transactions among nations of production and consumption.

Annually, the global production of construction aggregates reaches over 40 billion tons, making aggregates the largest mining sector by volume and value. Currently, the aggregate industry is shifting from sand to hard rock as a result of legislation limiting the extraction of natural sands and gravels. A major implication of this change in the aggregate industry is the need for understanding rock fragmentation and energy absorption to produce more cost-effective aggregates. In this paper, we focused on incorporating dynamic rock and soil mechanics to understand the effects of loading rate and water saturation on the rock fragmentation and energy absorption of three different sandstones (Red, Berea and Buff) with different pore sizes. Rock core samples were prepared in accordance to the ASTM standards for compressive strength testing. Saturated and dry samples were subsequently prepared and fragmented via fast and dynamic compressive strength tests. The particle size distributions of the resulting fragments were subsequently analyzed using mechanical gradation tests. Our results indicate that the rock fragment size generally decreased with increasing loading rate and water content. In addition, the fragment sizes in the larger pore size sample (Buff sandstone) were relatively smaller those in the smaller pore size sample (Red sandstone). Notably, energy absorption decreased with increased loading rate, water content and rock pore size. These results support the conclusion that rock fragment size is positively correlated with the energy absorption of rocks. In addition, the rock fragment size increases as the energy absorption increases. Thus, our data provide insightful information for improving cost-effective aggregate production methods.
