A hexagonal hexamer of water cluster is optimized by ab initio method using the 4-31G basis set. At this geometry the nonadditive many-body interactions are calculated. The ab initio calculation with large basis set [T. H. Dunning, J. Chem. Phys., 53, 2823 (1970); 54, 3958 (1971)] shows that a pentagonal unit is rather stable among several kinds of clustering units of water molecules.

A reduced condition for liquid-gas phase transition from the singularity of compressibility is derived using diagrammatic approach and is examined in the hard sphere system. The condition turns out that the Percus-Yevick and the Hyper-Netted-Chain approximation never conceive the idea of phase transition, and explains that the liquid-gas transition does not exist in hard sphere system. The solid-fluid transition is considered on the viewpoint of correlation function and diagrammatic analysis.

The study was carried out to investigate the proximate composition, amino acids, dietary fiber, ascorbic acid and minerals contents of seven edible wild vegetables; an Evening Primerose($S_1$), a Spiderwort($S_2$), the Flower of a Convolvulus($S_3$), So Ru Jaeng Yi($S_4$), Shoe Bi Rum($S_5$), O Yi Pul($S_6$), Jip Sean Na Mul($S_7$). Results as summarized as follows: 1. The moisture contents of samples were determined as 64.43~88.30% The largest amount of them was contained in a Spiderwort($S_2$) and the smallest was in a Jip Sean Na Mul($S_7$), 2. The crude protein contents of samples were determined as 2.71~8.10%. The largest amount of them was contained in a O Yi Pul($S_8$), the smallest was in the Spiderwort($S_z$). 3. A relatively large amount of total amino acids were determined in samples. The abundant amino acids existed in the samples were Glutamic acid(10%), Lysine(8%), Leucine(8%) and the content of Methionine was very low. The highest level of them was found in the Convolvulus($S_3$), 4,419.6 mg% and the lowest was Shoe Bi Rum($S_5$), 2,393.1 mg% 4. The Ascorbic acid contents of samples was determined as 55.99~31.8O mg. The highest level of them was found in the Jip Sean Na Mul($S_7$) and the smallest was in the Primerose($S_1$) 5. The mineral contents of samples were determined. A relatively large amount of K, Ca and Mg were found in the samples. Especially the level of Iron was higher than that of any other vegetables. 6. The contents of dietary fiber were determined as 31.8~79.9%. The highest level of them was found in the Convolvulus($S_3$) and the lowest was in the Spiderwort($S_2$). The highest level of them was found in the Convolvulus($S_3$) and the lowest was in the Spiderwort($S_2$). From the above mention, we can say that the contents of protein, fat, fiber, total amino acids and iron were abundant in wild grasses than that of any other wild and cultured vegetables. The contents of ascorbic acid, potassium, calcium and magnesium were similar and the moisture is significantly low compared with any other vegetables.

This research is an explorative research done on finding sights in documents related to landscapes that are described in personal essay collections of late-Joseon Dynasty, and to fathom the possibilities of finding the actual landscape by analyzing the landscape and features of the landscape. The target sight of this research is to find all the features and landscapes of the Nong-yeon Seodang 10 scenery that are described in Choi Dong-Jip(late-Joseon Dynasty scholar)'s Daeam Sunsaeng Munjip. The results are as follows: 1) a theoretical inquiry into Daeam Choi Dong-Jip and his descendent Baekbulam Choi Heung-Won(who had compiled Daeam Sungsaeng Munjip)'s background and Nong-Yeon Seodang has been done, 2) Nong-Yeon Seodang's location was found through historical documents and field investigations, and 3) the features of landscapes related to Nong-Yeon Seodang 10 scenery and its distribution and the significance were analyzed. Through this inquiry, organization of Nong-Yeon Seodang and the significance of its direction were reflected again, records on garden organization were checked, and a direction for continuation of research was suggested.

We show that $\frac{{\partial}x}{{\partial}{\gamma}}(t,{\tau},{\gamma},{\lambda},{\varepsilon})$ is a fundamental matrix of the variational system $\dot{y}=fx(t,x(t,{\tau},{\gamma},{\lambda},{\varepsilon}),{\lambda},{\varepsilon})y$ corresponding to the solution $x(t,{\tau},{\gamma},{\lambda},{\varepsilon})$ of $\dot{x}=f(t,x,{\lambda},{\varepsilon})$.

본 논문에서는 FeRAM을 주 기억장치 및 보조 기억장치로 활용하는 다중 채널 FeRAM 시스템을 설계한다. FeRAM 의 비 위발성과 저 전력 소모의 장점을 활용하는 한편 다중 채널을 이용한 병렬 처리와 FPGA 내부 버퍼를 사용을 통해 읽기/쓰기 속도를 향상시켰다[1].

본고는 지난 8월 일본식조협회로부터 받은 일본 계육산업의 전반에 대한 자료를 번역 정리한 것으로 우리나라의 계육업계에서도 참고할 내용이 있다고 보여진다. 내용 중 엔환율은 일본 엔화 100엔당 한화 800원으로 환산해 바로 볼 수 있도록 표를 편집한 것이다. 아울러 개념적으로 조금은 다른 부분들이 있어(예를 들면 출하 중량 : 일본의 출하 중량 1.7Kg KFC 출하를 위한 부분출하 후 생계중량 3.0Kg까지 사육 : 정육 유통 개념) 이를 감안하여 자료를 보아야 한다는 점이다. 이러한 자료를 통해 구체적인 일본의 계육산업을 돌아보고 파상적인 일본 시장이 아닌 실체적인 일본 시장에 보다 접근하는 계기가 되었으면 한다. 아울러 본 자료에는 유통 시장에 대한 내용이 보다 많이 소개되어 있다. 유통을 한번쯤 되돌아 볼 수 있는 기회가 되길 바란다.
