This study is to analyze on territorial education described in geography textbooks in Korea and Japan. The following is the result that shows similarities and differences of the geography textbooks when it comes to territorial education. Korea and Japan have a contrasting territorial background. However, both countries start their territorial education by learning the location and shape of their country. Japanese geography textbooks focus on what people in the world think of Japan, but in case of Korea, the geography textbooks focus on how Koreans look at the world. In short, the territorial education in Japan try to emphasize Japan from the view point of the world. The next common ground is that the two countries provide territorial models in their geography textbooks in order to increase understanding. However, the Japanese students are provided with these territory models much earlier than Korean students and these models help them visualize and solidify their concept of territory. And, the two countries both put great importance on teaching territorial sea. In Japan, they try to include EEZ(Exclusive Economic Zone) in their territory. Considering these facts, it can be concluded that Japan is enlarging their concept of national territory as maritime territory. Lastly, after learning of territory the two countries both treat on territorial problems. But Korea treats passively territorial problem as such Dokdo, but Japan treats actively their territorial problems. Like that, the contents of territorial education described in geography textbooks in Korea and Japan are similar in terms of selection, but differ in quality in terms of organization. Therefore, future territorial education in Korea will be actively and successively done through succession and sequence of geography curriculum.

National atlas map for provide various information is one part of National territorial Statatics Survey but National atlas map in 2004 year don't have stability and ability. National territorial Statatics Survey in 2005 years have octuple data compare with data in 2004 years but have only one map. One map is going to provide with stability and ability. We don't use DBMS, But We make a similarly struct in file based program. We programmed system of dynamic-linked data with spatial data. To dynamic-linked system, we make search engine to based index struct and make combobox search system. spatial data only have index codes(year, national terrial indicator, area). If spatial data request specfied data, search engine search index code and provide DB data. New system is middle step of using DBMS. We redraw map for display real Korea area (with dokdo). New map is shape and similar Korea map.

Nowadays, a region is mainly constructed by a variety of subjects intentionally. Therefore, it is needed to consider the concept of the region reflecting the standpoint of various related subjects pertinently to understand today's region. Subjectivities, differences, and power relations are representative elements which play important roles in the process of constructing the region. And the inclusive concept of these elements is the tenn of 'regional identity'. The regional identity is constructed through the process of institutionalization, and this process of building identity is the process of constructing the region. The local newspaper is a representative one of the various factors influencing the process of institutionalization and serves as an important clue in understanding the process of constructing the region in Korea. In this point of view, this study also analyzes the standpoint and influence of the various institutions operating in the process of constructing the region through the articles in Hong-Seong Times. According to this study, institutionalization process have proceeded very actively in Nae-po region. But it is likely that institutionalization process have not reached to the stage of constructing region.

We researched the reproductive ecology of pale chub, Zacco platypus that inhabits Gajeong-cheon and Wonju-cheon that are a tributary to the Han river. The nuptial organ was formed on the head part, the anal fin and the tail part in male, the change of nuptial color was outstanding. By their changing body shape, the anal fin was extended and body depth came to be high during the spawning season in both sexes. Territorial male of defending behavior were head butting, rotated fighting, parallel swimming, biting and expelling. After pale chub located himself from the upper of the female that was approached to the side parallelling with the female, male and female spawned digging sand with their anal fin by vibrating and any parental care of the eggs was not taken. The spawning interval and lasting time were relevant to individuals density of spawning ground.

Dokdo has historical and political meaning in relation to the territorial problems with Japan. The area can be the main factor to explain the formation and development process of East-Sea as exposure volcanic island at East-Sea with Ulreong-island. Accordingly, it also has an important meaning of physical geography aspects In this research, it is perceived the geomorphological development process of slope due to the salt weathering which is considered as the most important factor to understand whole geomorphology of Dokdo. And researched how a geomorphology of this sort affects to animal and plants. The peculiar geomorphology is tafoni which is a weathering geomorphology and one of the remarkable geomorphology in preservation of Dokdo. Tafoni at west part of Dongdo is distributed intensively near shoreline which is composed tuff. The shape of tafoni is mainly massive, circle and oval in Massive tuff breccia layer also is formed toward horizontality bedding direction in Bedded lapilli tuff. Tafoni in Dokdo is constituted after middle of Holocene. This fact can be proved by ranging at surface of sea-cliff which is formed wave erosion after middle of Holocene sea-level reaching to present level. Tafoni is also the most contribute factor of geomorphology dissection of Dokdo as it is eroded the bed rock with salt weathering. In bottom part of tafoni it has an important function for habitat of birds. Herbaceous plants are on it. To procrastinate of bed rock dissection by growth of Tafoni, conservation of vegetation and soil are most important factor.

Spawning behavior and development of eggs and larvae of Mugilogobius abei were observed in the laboratory at Pusan, Korea. The adult male of Mugilogobius abei was observed making nest-like spawning-bed to lay eggs and showing territorial and courtship behaviors. The eggs were transparent and spherical in shape, measuring 0.40~0.50 mm in diameter. They have a bundle of adhesive filaments at their basal end and a cluster of small oil globules. The eggs became ellipsoid shape after the insemination and measured about 0.93~0.96 mm on the long axis. Hatching began about 110 hours after fertilization at water temperature of $24.5{\sim}25.5^{\circ}C$. The newly hatched larvae were 2.04~2.10 mm in total length, with 24~25(8~9+16) myomeres. Many melanophore and guanophore are distributed on eye cups, gas bladder, optic vesicle and the caudal region. Four days after hatching the yolk and oil-globule were completely absorbed and the larvae attained a total length 2.20~2.35 mm. The larvae swam actively in the aquarium and start to practice feeding on the rotifer. Twelve days after hatching, the larvae averaged 3.20 mm in TL and the caudal notochord flex at $45^{\circ}$. Rudimental second dorsal, anal, caudal and ventral fins are also formed. The larvae attained 10.40~10.80 mm in TL, 35 days after hatching, are found to start the bottom-life after having completely formed first dorsal and ventral fins. The larvae reached the juvenile stage at 50~60 days after hatching and attained 15.37~20.25 mm in TL. At this period all scales appeared on the body.
