Complexes of the type[Co(T)(L-pro)], where T is the quadridentate $N_2O_2$-type ligand, N,N'-dimethylethylenediamine-N,N'-diacetate or N,N'-dimethylethylenediamine-N,N'-di-$\alpha$-butyrate, have been prepared. The complexes were separated into the two stereoisomers, $\Delta$-s-cis-[Co(T)(L-pro)] and $\Lambda$-s-cis-[Co(T)(L-pro)]. They were characterized by their proton magnetic resonance, absorption and circular dichroism spectra, elemental analyses.

남대천 유역의 어류상을 조사한 결과 총 5과 11속 13종으로 나타났다. 이 가운데서 한국고유종의 출현은 볼 수 없었다. 전 지역에 걸쳐 우점종은 가시고기 Pungitius sinensis $(61.49\%)$, 버들개 Phoxinus lagowskii $(28.26\%)$ 및 갈겨니 Zacco temmincki$(2.29\%)$로 나타났으며, 희소종은 참붕어, 가물치 및 빙어로 나타났다. 잉어과 어류가 5종으로 가장 다양하게 나타났으며, 다음 기름 종개과 어류가 4종 출현하였다. 본 조사유역인 남대천은 수질이 오염되어 있으므로 수질정화는 물론 남획으로부터 어류가 보호되어야 하겠다.

Unsan alluvial plain is the backmarsh of Seomseokcheon which is a river originated from Chilseongdae(954m) on Mts Taeback, flowing into Donghae in southern Kangreung City, Kangwon Province. The vegetation change, geomorphic develoopment and depositional environment during the late Holocene have been investigated, using the methods such as boring, pollen analysis and radiocarbon dating. Because the deposits fo the study area are mainly consisted of peat and paety sand, they contained many pollen fossils. The peat layer has been sedimented since the high sea-level periods, 3,200 y. BP, and the records of vegetation change until now has well preserved here. According to archeological researches and the results of pollen analysis in east coast of Korea, it is supposed that the prehistoric rice farming in this area has begun since ca. 1,800 y. BP.

This study was conducted to investigate decomposition of livestock manure in soils cultivated with Chinese cabbage along an alitude gradient. The experiments were conducted in Kangreung (17 m above sea level), Bongpyeong (430 m above sea level), and Daekwanryeong (800 m above the sea level) in order to assess the decomposition rate and accumulations of livestock manures depending on different altitudes. During chinese cabbage cultivation, the decomposition ratios of organic matter derived form livestock manure expressed as % of the initial organic matter content were 42~48% for Kangreung, 26~29% for Bongpyeong and 10~14% for Daekwanryeong. Changes in air temperature with altitude might be a main factor affecting manure decomposition rates.

The purpose of this study was to investigate the fatty acid composition and the rancidity of commercial deep-fat fried foods in Kangreung. the 7 kinds of samples were purchased form snack corners in 3 markets at AM 10 and PM 6 o'clock. The acid value, peroxide value and TBA value of the deep-fat fried foods were determined and the fatty acid composition were analyzed. The range of acid value was 0.45∼1.79, that of peroxide value was 1.24∼8.64meq/㎏,and that of TBA value was 12∼140 in all samples. There was significant difference in most of all samples by purchasing time and kinds of samples. But there was not specific tendency by purchasing times in each sample. Most of the acid value, peroxide value and TBA value of the samples fried with meats or sea foods showed higher value than the that of samples fried with vegetables or seaweeds. The fatty acid composition of the total lipids in the deep-fat fried foods were similar to one another. The major fatty acids were linoleic acid(C18 : 2) , oleic acid(C18 : 1) in order of content. Minor fatty acids were palmitic acid(C16 :0), linolenic acid(C18 : 3), stearic acid (C18 : 0) in order of content. the P/S ratio was the range of 2.12/1∼4.71/1 and the that of the samples fried with meats was the highest among samples. so there was the same tendency in this result between the chemical properties(acid value, peroxide value, TBA Value) and fatty acid composition. As a result of acid value and peroxide value in this study, the commercial deep-fat fried foods in Kangreung was safety.

Tumuli located in Chodang-dong in Kangreung City are sitesexcavated by the Museum of Kangreung University in 1993.Ofthese sites, a gilt bronze crown and gilt bronze sword with ring pommel with a tri-leaf ornament were excavated from the B-16tumulus. Underneath the gilt bronze crown was the gilt bronzes word with ring pommel with tri-leaf ornament, and these artifacts were treated with Polyurethane foams on the spot followed by special measures for conservation. This manuscript describes measures for conservation andanalysis with regard to the gilt bronze crown, gilt bronze sword with ring pommel with tri-leaf ornament and gilt bronze beltornaments. Bronze on the gilt bronze crown was completely corroded, therefore it was consolidated together with soil in the back of the artifact with Paraloid B72 after cleaning. Polyurethanefoams bottom was finished by applying the mixture of Epoxy resinAW106 and HV935K with soil. On the sword with ring pommel, the wooden part of the hilt was coated with Paraloid B72 (in Xylene) and the blade was consolidated with Paraloid NAD-10 30% after desalting with Sodium sesquicarbonate method. The gilt bronzebelt ornaments were treated with 3% Benzotriazole, coated with Paraloid B72 and then joined by using Cyanlacrylate. Specimens for the gilt bronze crown and gilt bronze belt ornaments were produced and gilding layers were examined under a metallographic microscope. The gilt bronze crown and the gilt bronze belt ornament maintained relatively good gilding quality with uniform gilding layers. Analysis of wood for the sheath of the sword with ring pommel revealed it to be Juglans mandshurica. Further more, analysis of constituents for a blue colored grassbead from dissolution of Polyurethane foams found it to be from the $Na_2O$-CaO-$AI_2O_3$-$SiO_2$ family.

이 논문은 강릉과 원주지방의 오존의 일변화의 특성을 분석하였다. 원주지방의 오존의 일변화는 대도시 지역에서 관측되어지는 오후에 최대치, 일출부근에 최소치를 보여주고 있다. 그러나 강릉지방의 일변화에서는 오후에 최대치를 보여주나 새벽 3시경이 2차 극값이 관측되어졌다. 3차 극값의 경우 오후 최대 값보다 높은 값이 종종 관측되어졌다. 이와 같은 새벽에 발생하는 오존 상승은 일년 내내 관측되어졌으나 그 양과 범위에서 봄철이 가장 뚜렷하였다. 이와 같은 새벽 오존 상승에 대한 원인을 알아보기 위하여 기상인자와 오존의 상관관계와, HYSPLIT모델을 이용하여 공기의 기원을 조사하였다. 새벽 오존 농도 상승이 나타나는 날은 바람이 강하고 온도가 상대적으로 높은 날이었다. 새벽오존 농도 상승이 일어날 때 모델을 이용한 공기의 기원을 분석해본 결과 서풍이 불면서 하강운동이 동반한 경우였다. 이러한 분석결과는 편서풍이 강하게 부는 봄철에 대도시가 밀접한 강릉의 서쪽 지역에서 이동되어온 오존의 영향에 의한 것으로 사료되어진다. 이런 경우 밤에도 바람이 강하게 불어 강력한 혼합현상에 의해 오존이 풍부한 대기 상층의공기가 하부로 유입되면서 지표 부근 오존의 양이 증가한 것으로 보인다.
