This study searched for comparison with geography of Qing China, origin of geographical name, people's feature and costume, description on regional geography, and perception on locality on view of a geographer, Ji-Won Park, a renowned Korean scholar of practical learning on the late 18th century. This study on the first three chapters of his Yorha Ilgi - "Crossing the Amnok(Yalu) River("渡河錄")," "Several Records on Senyang("監京雜識")," and "Writing Essays, Riding Horses("馹迅隨筆")," focusing on landscape of Qing China, inquiry on geographical name, feature and costume, and descriptions on locality, gives a glimpse on Park's geographical view on geography of Qing China. His writing style to compare landscapes between Korea and Qing China, full of his love for Korean landscape, is very delicate and clear, Although he sentimentalized when he passed through Bonghwang-castle(鳳凰城) in China, his subtle and beautiful writing explains that land and mountains in Han-yang(Seoul) are much more wonderful than those in China. His vivid depiction of landscape and weather on his way in Qing China is remarkable and explanation on geographical names like Parhae(渤海), Yoha(遼河), Taejaha(太子河), Senyang(瀋陽) etc. is enough to stimulate readers' curiosity on geography.

This study was conducted to analyze the characteristics of records related to Korea shown in the cataloging records of national libraries of the main 10 developing countries in Asia and Africa. The results are as follows. To begin with, Korea-related records in most national libraries are very poor and under 0.1% of the library. Except for National Library of Viet Nam, the figure is under 3,000 volumes and generally 2 times less than Japan related records. Second, except for National Library of Iran and Viet Nam most national libraries romanize Korean materials, there are not marked with the original Korean language and unfeasible Hangeul search. Third, on investigation of the subject distribution in sub criteria of Korea-related records, subject related to history and economy is largely shown in the highest rate. Fifth, among the Korea-related subject heading, Taekwondo is marked with distinction from Karate in most libraries except for 7 national libraries. Dokdo is marked with the geographical name of 'Korea' in 7 national libraries and East Sea (Donghae) already is marked with 'Japan, Sea of' in 7 national libraries. Amnokgang, Dumangang, and Baekdusan-related records did not search at all in most national libraries.

This paper is aimed to study the late Neolithic Age in North Korea in order to closely examine a transition process into the Bronze Age in the Korean peninsula. Thus, the pottery with lightning design was selected as target data. Since the pottery with lightning design is fundamental data that North Korea's archeologists have used for chronological recordings of the late Neolithic Age in the northwest region, the parallel relationship between the eastern and the western region was established with comparison of pottery with lightning design in the northeastern region. The examination focuses on data that cover the target region of the pottery with lightning design of the adjacent Southern Primorskii region including the counterpart of the northwestern and the northeastern region. As a result, some attribute analyses revealed that the pottery with lightning design was affected by the counterpart of the northwestern region near the Yalu River. Prior to genealogical and chronological recordings of the pottery with lightning design in the northeastern region, the pottery with lightning design in the northwestern region was recorded chronologically in order to examine its specific development process. Consequently, in the second period of the Neolithic Age, the pottery with lightning design in the northwestern region was assumed to have an impact on the counterpart in the northeastern region. The classification of the pottery with lightning design in the northeastern region shall be based on 4-period development. According to this classification, the pottery, which was found in the Tumen river basin, was thought to belong to the first period. The pottery went through genealogy differentiation in the second period and when entering into the third period, the pottery spread to inland of south Primorskii. The pottery was assumed to exist in the southern Primorskii region until the tip end (the fourth period) of the Neolithic Age. It is assumed that considering the fact that climate change led to the agriculture movement, Zaisanovka culture, i.e. the late Ne Neolithic Age, moved to the southern Primorskii region along the Tumen River basin.

Round piles of Korean larch were excavated from the foundation of ex-Chosunchongdokbu (ex-Chosun Governer-General Building), which was constructed in 1916 and dismantled later in 1996. By the record (Huh, 1996), the Korean larch logs were logged from the Yalu river area near Mt. Baekdu in North Korea. At present, however, Korean larch is not so popular in South Korea. The latewood ratio profiles and strength properties (longitudinal compression, shear, longitudinal tensile, and bending) were obtained. The ratio of latewood from pith to bark increased up to 25 years, and then it showed constant tendency at 40% with some variances. From the microscopic observation, however, the latewood ratio decreased from the heartwood to the sapwood. Compression strength was greater and bending strength was a little lower than the previous reports (references 13~15), which might be attributed to the strength reduction of old structural members by aging or damage in the compression specimens than the bending ones. The flat-grained specimens for the shear and tension test showed higher coefficient of variation (COV) than the edge-grained ones. For the better comparison of results, in case of shear and tensile strength tests, the strength values of the edge-grained specimens were thought to be adopted rather than those of flat-grained ones.

The water quality at Seomjin River stream was surveyed at 8 sites of main stream and 4 sites of tributaries for 6 months from April to September in 1989. The overall results are summarized as follows: 1. Do concentration of main stream ranged from 7.5 to 9.0 ppm. 2. The average $No_3-N$ content of main stream was increased to 3.86 ppm at June, thereafter it was decreased by dilution with rainwater. 3. The water quality of Seomjin River stream was suitable for the irrigation source with the exception of site 8 where the contents of EC, $Cl^-$ and $SO_4\;^{2-}$ were very high according to the influence of sea water. 4. In the influence of tributaries on changes of the water quality along the Seomjin River, the water quality of main stream was deteriorated with inflow of Osu-cheon and Yo-cheon in the middle stream, but thereafter it was recovered with inflow of Boseong River and Hwangjeon-cheon. 5. The Yo-cheon was rapidly polluted by the sewage of Namweon city, that is, contents of COD and $NO_3-N$ were incresed from 0.97 to 7.10 ppm and from 1.86 to 3.11 ppm respectively.

The purpose of this paper is to analyze the meaning of of "Nikolai Garin - Mikhailovsky's the "Joseon tale". talks about the origins of the Joseon Dynasty and the Qing Dynasty. In this paper, we revealed the features of the form of "Otter Legend". And analyzed the confrontation between Nurhachi's family and Yi Seong-gye's family shown in the story. The result is as follows. is complex tale. The start of is 'the typr of Yaraeja'. Next is the story of Myoung-Dang. Myoung-Dang is deep in the water. also has anecdotes of Jeong, Chung-shin. rearranged at least three stories or more. transformed each type of stories, communing the different patterns of stories with different logic. The basic logic of the transformation was to maximize the confrontation between the NuruhachI and Yi Seong-gye clans, the origins of Manchuria and the Chosun Dynasty. As a result, the sacredness of Nurhachi's Family, the origin of the Qing Dynasty, was expanded. On the other hand, Yi Seong-gye s Family was less extraordinary than Nurhachi's Family. Also, the ability of the person is also inferior. This is not the yearning for the Qing Dynasty. This is because the Qing Dynasty and the Joseon have the same pedigree. shows that the Qing Dynasty's experiences should be shared since the Qing Dynasty was born of another clan of Joseon. This is a new perception of Qing Dynasty. This is similar to the interpretation that dragged the Qing Dynasty's history into the Joseon's ethnographic historical point of view.
