This study develops a GIS-based system which examines the adequacy of the Groundwater development project before the actual designing of the project. Using the system developed here, we can transfer simulation results obtained by WHPA regarding Groundwater levels in new development projects into GIS. We can also judge whether a Groundwater development project should be permitted through examining overlaps of the effects of the development and comparing with other pollutants. Since a two-tiered system which shares DB using inter- and intranets is developed, all the departments in the ministry of agriculture and forest and the agriculture base corporation can share accurate, reliable and latest information related to Groundwater.

The applicability of a well-type autotrophic sulfur-oxidizing reactive barrier (L $\times$ W $\times$ D = $3m\;{\times}\;4\;m\;{\times}\;2\;m$) as a long-term treatment option for nitrate removal in groundwater was evaluated. Pilot-scale (L $\times$ W $\times$ D = $8m\;{\times}\;4\;m\;{\times}\;2\;m$) flow-tank experiments were conducted to examine remedial efficacy of the well-type reactive barrier. A total of 80 kg sulfur granules as an electron donor and Thiobacillus denitrificans as an active bacterial species were prepared. Thiobacillus denitrificans was successfully colonized on the surface of the sulfur granules and the microflora transformed nitrate with removal efficiency of ~12% (0.07 mM) for 11 days, ~24% (1.3 mM) for 18 days, ~45% (2.4 mM) for 32 days, and ~52% (2.8 mM) for 60 days. Sulfur granules attached to Thiobacillus denitrificans were used to construct the well-type reactive barrier comprising three discrete barriers installed at 1-m interval downstream. Average initial nitrate concentrations were 181 mg/L for the first 28 days and 281 mg/L for the next 14 days. For the 181 mg/L (2.9 mM) plume, nitrate concentrations decreased by ~2% (0.06 mM), ~9% (0.27 mM), and ~15% (0.44 mM) after $1^{st}$, $2^{nd}$, and $3^{rd}$ barriers, respectively. For the 281 mg/L (4.5 mM) plume, nitrate concentrations decreased by ~1% (0.02 mM), ~6% (0.27 mM), and ~8% (0.37 mM) after $1^{st}$, $2^{nd}$, and $3^{rd}$ barriers, respectively. Nitrate plume was flowed through the flow-tank for 49 days by supplying $1.24\;m^3/d$ of nitrate solution. During nitrate treatment, flow velocity (0.44 m/d), pH (6.7 to 8.3), and DO (0.9~2.8 mg/L) showed little variations. Incomplete destruction of nitrate plume was attributed to the lack of retention time, rarely transverse dispersion, and inhibiting the activity of denitrification enzymes caused by relatively high DO concentrations. For field applications, it should be considered increments of retention time, modification of well placements, and intrinsic DO concentration.

The writer of this study analyzed the traces that are made by revising and replenishing after finishing engraving of Chojodaejanggyeong into the Vol.60 Abstract of Tripitaka Koreans 周本 Hwayemgyeong. It can be a clue that proves the revising of Chojodaejanggyeong was considerably complete.

본고는 무구정광대타라니경에 사용된 무구신자의 성격을 구명하기 위해 무주신자와 이를 제정한 측천무후에 대해 선행연구를 통해 살펴보고, 무주시대에 적용된 무주신자의 용례를 고찰하여, 본경에 사용된 례와 비교 분석한 것이다. 먼저 본경에 사용된 신자의 자형을 무주시기에 사용된 신자의 자형과 비교를 해본 결과, "초.증.수"자의 신자들은 상당한 차이가 났다. 또한 신자의 조합원리와 의미상에서 비교해 본 결과 더욱 차이가 있었다. 다음으로 신자사용의 적용례를 비교해 본 결과 역시 비교가 안될 정도의 차이를 보여주었다. 따라서 본고에서는 본경에 사용된 신자와 무주시기에 사용된 신자사이에 시간적.공간적으로 상당한 거리가 있기 때문이 이와 같이 자형과 사용례에서 극심한 차이가 있는 것으로 이해하였다.것으로 이해하였다.

Seasonal variations of major contaminants in groundwater around livestock burial areas in Gyeonggi province, Korea, were examined. Seven typical contamination indicators ($NO_3$-N, $NH_3$-N, chloride, pH, DO, ORP, and EC) were monitored in groundwater samples collected from 84 wells located within 60 m of livestock burial sites for the leachate plume emanating from the livestock burial sites. The monitoring results of pH, DO, ORP, and EC revealed minimal seasonal variations, providing no evidence for leachate plumes. The $NO_3$-N concentrations were below 30 mg/L and exhibited minimal seasonal fluctuations, even in the wells located close to (< 20 m) the burial sites; the $NH_3$-N and chloride concentrations also showed similar results. The contamination indicators examined in this study indicate that the observed groundwater contamination is primarily from preexisting pervasive contamination due to agricultural activities and livestock farming, not leachates derived from nearby livestock burial sites.

This study is about the new examining of the books' period for publication, system, and the relationship with the original script by considering the books of 'Sambon Hwayemgyeong of Suchangpan series' as a whole. As a result, the books of 'Sambon Hwayemgyeong of Suchangpan series' are arranged with four types, '11th century edition'(estimated the first published book), 'Suchangsanyun edition(1098) and Sookjongyeongan edition(1096-1105)', '12th to 13th century edition', and 'Haeinsa Sagan edition(12th-13th century)'. Among them, especially '11th century edition'(estimated the first published book) is the book that has been known as a 'Y$\ddot{u}$an book', '12th century edition' or 'bokgakbon of the Kitan(or Seoha) line's book', and 'Sookjongyeongan edition (1096-1105)' and so on.

Historical development of cataloging rules in Korea can be divided into the period of traditional single-entry cataloging, the introduction period of western cataloging rules, the period of international standardization, and the period of MARC. This study tries to review catalog organization relating to catalog structure and choice of headings, and rules for description relating to idenhfymg items from the period of traditional single-entry cataloging to the introduction period of western cataloging rules in Korea.

The purpose of this research is to establish the classification system of Chojo Tripitaka Koreana, and analyze the contents of its print held by Horim Museum. Major discussions included are as follows: First, the characteristics and significance of Chojo Tripitaka Koreana are examined. Second, based on Taejang Mongnok, which is the Bibliography of Tripitaka Koreana, the classification system of Chojo Tripitaka Koreana is established. Third, by closely examining 10 titles and 21 volumes of Chojo Print from the collection of Horim Museum, it is proved that its contents and sequences in scriptures of Chojo Print are the same as those of Taejang Mongnok and therefore the classification system in this research is adequately established. Fourth, it is found that in the Avatamska Sutra held by Horim Museum, five volumes of the Avatamska Sutra which originally consists of fifty volumes, are included. And it is also found that in Chaejo Tripitaka Koreana, the Avatamska Sutra, which consists of sixty volumes, were inserted in their place.

This study is made of proofreading some documents about ‘Tripitaka Koreana’, which was unknown and not noticed quite well until now and is also for montemplating the features of ‘Qidanzang’ that were accepted in ‘Tripitaka’. By all the researches the following facts were found out. First, ‘Qidanzang’ included in ‘Tripitaka’ were all 18 cases. Second, ‘Qidanzang’ that were corrected and accepted into ‘Tripitaka’ were 42cases. Third, ‘Qidanzang’ that have errors at comparing documents were all 11cases. Fourth the sutra that were accepted in the comparative book were all 57 cases. Fifth, unaccepted sutras , which were found out at comparative documents, were 4cases. At last, from the analysis abouve, we notice that most of the ‘Qidanzang’, not part of it, were accepted into ‘Tripitaka Koreana’ and like the previous viewpoint, ‘Qidanzang’ was an excellent book but it also had a few mistakes.
