One of the major problems comparing the old map, Daedongyojido, with modern maps in order to measure the spatial error of the map it a projection of the modern map selected. This study focuses on the map projection of Daedongyojido. Three different approaches are used: comparing the spatial pattern of Daedongyojido with maps of different projection, examining materials related to old maps and books which were written by Jeongho Kim directly or indirectly, and the data sets which were available at the mid nineteenth century and could be used for map production. A couple of map projections are possible to that of Daedongyojido, but TM(Transverse Mercator) projection is one of the closest projections.

The production period of Daedongyeojijeondo is estimated from 1861 to 1866 in consideration of place names. Daedongyeojijeondo is elaborated enough that there are the latest data in, especially is better than Haejwajeondo that is a representative map in the 19th century in marking distance. Daedongyeojido is an official map for national defense and administration, on the other hand Daedongyeojijeondo is a popular map in which social and economical contents are included. The recognition of mountains and rivers based on organic view of the land is also represented in Daedongyeojijeondo, and the principle of the whole of mountains and rivers is well reflected. It is far better than modem maps in the expression of road system and distances, tidal area in rivers.

The study is to systematically review "DaedongYeojiJeondo", the mid-sized wood block map of Chosun to shed light on the cartographic characteristics not discovered by previous studies. First it was discovered that Kim Jung-ho is the developer of the map as the distance information from Seoul to towns is identical with the information on "Daedong Jiji" the manuscript map drawn by Kim Jung-ho himself (assumed to live from 1804~1866) that is still remaining unfinished. Second, the information Kim Jung-ho wanted to specify most precisely and specifically was distance from Seoul to towns and for this purpose he invented unique symbols for towns in tiny size on the map. Third, in selecting information to mark on the map including road network, street information, mountain routes and streams and location of islands, "DaedongYeojiJeondo" is not just a simple smaller copy of "DaedongYeojido" but an independent creative work as it is much different in many aspects of quality. Forth, but still "DaedongYeojiJeondo" and "DaedongYeojido" have something in common in the fact both of them tried to mark land and mountain routes and streams most precisely and specifically.

실체 유물론과 인과 결정론이 개인의 자유와 동일성을 실질적으로 열어주려면 사건 원인 외에 행위자 원인의 여지를 허용해야 한다. 그 두 가지 원인은 법칙적 일반적 결정의 개념과 합리적 개성적 결정의 개념을 지니고 있다. 개성의 인과적 역할은 법칙화할 수 없는 물질성의 여지를 남긴다. 바로 그 가능성이 인간의 자유와 동일성의 실질적 복권의 가능성이다.

This study is to comparatively analyse the place names on "Cheonggu-do"("靑邱圖", manuscript edition, 1834) and "Daedongyeo-jido"("大東輿地圖", woodblock-edition, 1861). Though the same person-Kim, Jungho(金正浩)- published those maps, and the latter was based on the former map, place names on thos maps are very different. The hypothesis is that those different information on maps were not from the cartographic, but from the social aspects at that times. The whole township names on "Cheonggu-do" were erased in "Daedongyeo-jido". The other names such as mountain, river, port, castle, beacons, official waer houses were recorded instead of township. Especially military names which were recorded newly in "Daedongyeo-jido", such as castle, beacon, ranches for the defense of nation, was geographical distributed in a strategic and key point in the northern and coastal area. This shows that there were rules for the mapping of "Daedongyeo-jido" and those rules could be come from the social demand.

Lateral roots of soybean sprout might reduce the quality. The study was done to measure the effect of light quality treated during 24 hour imbibition or 6 day culture on growth and development of soybean sprouts on the 6th day after culture. With the soybean seeds imbibed in 4 ppm benzyladenopurine (BA) solution for last 6 hours of the imbibition, blue and red lights were treated during the imbibition, but during 6 day culture, blue and red or far-red light treatments were done for 50 minutes or 5 hours a day, respectively, the periods taking for their cotyledons to turn green color, On the 6th day after culture, the soybean sprouts were classified by 4 categories on the base of hypocotyl length;＞7cm, 4 to 7cm, ＜4cm and non-germination, and their lateral roots, hypocotyl diameters and fraction dry weights were measured. Blue and red lights treated during the imbibition completely blocked lateral root formation regardless of the lights treated during the culture, and showed nearly the same rate of hypocotyls of longer than 4cm. The period of each light treatment forced during the culture did not influence the growth of soybean sprouts. far-red light treated for 5 hours everyday, however, had the least rate of seed germination and hypocotyls of longer than 7cm of the light quality treatments. In addition, red and far-red lights almost equally having the commercial soybean sprouts of longer than 4cm hypocotyls move elongated and selenderized than blue light and dark treatment, meaning the growth and morphology of soybean sprouts was affected by light treatments during the culture.

The yield of cellulase derived from Trichoderma $(O_2-1)$ was remarkably varied with various concentration of ethanol and acetone in purification of the enzyme. In the purification with ethanol of ${\beta}-glucosidase$, the best result was obtained in the concentration of 60% and, of CMCase and of filter paper disintegrating enzyme 80%. And in the purification with acetone of ${\beta}-glucosidase$, filter paper disintegrating enzyme, and CMCase, in the concentration of 60%, 80%, and 90% respectively, was shown the best yield. The activities of crude Cellulase preparation could be seperated into few of fractions by column chromatography with Silica gel, Cellulose powder, and gauze. Most of CMCase, avicelase, and ${\beta}-glucosidase$ were eluted, but most of filter paper disintegrating enzyme and the rest of enzymes mentioned the above were absorbed, and were eluted with water. Therefore, it was considered that CMCase is different from filter paper disintegrating enzyme in properties. The relative activity of CMCase was different from that of avicelase in the peak of elusion part. And it was considered that filter paper disintegrating enzyme and cellulose powder saccharifying enzyme was seperated respectively as absorption part and non absorption part. The auther came to the conclusion that at least there were more than three sorts of cellulase in Trichoderma $(O_2-1)$ cellulase preparation.

문장의 논리적인 내적이며 형식적이라고도 말하여지는 구조는 단순한 구문론적인 것이라기 보다는 우리의 외적 세계 이해의 범주라고도 말하여져 왔다. 이러한 이해에는 검증이 어렵다는 이유에서 쉽게 받아들일 수 없는 점이 있으나, 실제의 언어 이해에서 부인 할 수 없는 작용을 하는 것은 어쩔 수 없다. 원자 문장에서의 이러한 논리적인 제약이라고도 말하여지는 것은 거의 형이상학적인 측면이 있더라도 언어의 수학적인 성질로 받아들이지 않을 수 없다. 그래서 여기에서는 원자 문장 형성에서의 수학적인 성질들을 말하여 보고자 한다.
