Jaroslav Bařinka: Reflections on Czechoslovak- Korean Cold War Encounters
( Vladimír Hlásny ) 서울대학교 규장각한국학연구원 2021 Seoul journal of Korean studies Vol.34 No.2
Jaroslav Bařinka, a leading Czech scholar of Koreanology, founding figure of Koreanology in Czechoslovakia, and among the longest-serving Czech diplomats operating in both Koreas, died at the age of eighty-nine on October 3, 2020. Bařinka made invaluable contributions introducing Korean traditional culture, archeology, and literature to non-Korean audiences, based on his extensive travels in the Koreas, Japan, and China spanning half a century. He served as an interpreter and Second Secretary at the Czechoslovak embassy in Pyongyang starting in 1955 and intermittently after that until 1976. He was the first Czech civilian to visit the ROK in 1970, returning there during the 1988 Olympics and in 1991 as Czechoslovakia’s―and in 1993 Czechia’s― first chargé d’affaires to Seoul. He was famous for his meticulous note-taking, sharp eyes, and technical knowledge. To the moment of his death he could talk at length about metallurgical deposits across Czechia and North Korea, their extraction processes, and their chemical properties―or about Confucian writings and architecture. This article recounts Bařinka’s experiences from his long career in Korean scholarship, interpretation and diplomacy, with the aim of shedding light on Czechoslovak-Korean political relations, scholarly and cultural exchanges, and physical encounters from the 1950s to the 2000s. It is a record of conversations based on fifteen long interviews with Bařinka which took place between October 2014 and August 2019, with the objective of tracing the beginnings of Koreanology in Czechoslovakia. The content and style follow Bařinka’s presentation as closely as possible, and errors, omissions, and biases are not carefully flagged, with the aim of accurately reflecting Bařinka’s own narrative. In instances where editorial intervention is warranted, references to sources of additional information and corroborations of Bařinka’s account are separated clearly from Bařinka’s own account.

Political Migration of Korean Activists through Czechoslovakia in the Post-World War II Period
( Vladimír Hlásny ),( Jung Byung Joon ) 서울대학교 규장각한국학연구원 2017 Seoul journal of Korean studies Vol.30 No.1
The existence of intra-Korean migration between World War II and the Korean War is well known: North Korean landowners and Christians, South Korean communists, and millions of war refugees fled across the 38th parallel, resulting in over two million separated families on the Korean Peninsula. But there were several Koreans who had resided in the US for decades who found their way to Pyongyang via Prague between World War II and the height of the Cold War. Why did they leave for North Korea? Why through Czechoslovakia? What were their fates after they landed in North Korea? This is a story of eleven Korean activists, from three groups, who left their footprints in Czechoslovakia on their journey between the US and North Korea. Eight of them continued to Pyongyang, two returned to the US, and one remained in Czechoslovakia for good. Eight vanished after arriving in Pyongyang, two survived and led comfortable lives in the US, and one took his own life in desperation in Czechoslovakia. We explore the settings in which their stories unraveled, the destinies of the eleven migrants, and the links among them, corroborated by witness interviews and newly discovered materials from Korean, US, Czech, and Russian archives.

Population genetic studies were carried out on randomly selected and unrelated individuals from Korean(n= 379) using 9 short tandem repeat loci FGA, VWA, D3S1358, D18S51, D21S11, D8S1179, D7S820, D13S317, and D5S818, respectively. After electrophoresis, 18 alleles were identified for FGA, 7 alleles for VWA, 8 alleles for D3S1358, 16 alleles for D18S51, 15 alleles for D21S11, 10 alleles for D8S1179, 9 alleles for D7S820, and 9 alleles for D13S317. No deviation from Hardy-Weinberg equilibrium was found. Some statistical parameters of forensic interest, such as observed/expected heterozygosity, mean exclusion channce, power of discrimination and polymorphism information content were determined. The results for RGA, D21S11, and VWA showed no differences of allele frequency between the different Korean population groups.

?? -tree is widely used as index structure in information retrieval system such as digital library and World-Wide Web information retrieval engine. The Information retrieval ststem often reflect all information collected independently by robot agent into their current indexes and directories at one time. When many key values are inserted into an index implemented as ?? -tree, much processing time will be required to search and to split nodes to look for the leaf nodes inserted. In order to Solve this problem, in this paper, we propose BULK_ADD strategy which creates a new ?? -tree by merging the existing ?? -tree and the set of data to be inserted. We also analyze performance of proposed BULK-ADD strategy. From the performance analysis, we found that the proposed strategy has better performance than the algorithm which inserts repeatedly into ?? -tree, when the nember of inserted data objects is over specific ratio(4%) of the existing index size. This ratio can be used as the criteria selecting the scheme to insert multiple data objects into ?? -tree with the minimum processing time in information scheme to insert multiple data objects into ?? -tree with the minimum processing time in information retrieval systems. At the same time, the period of index update can be determined on the basis of this ratio, if we can predict the data quantity newly collected during a specific time interval.

치환된 perovskite형 복합 산화물 LaCo_1-xCu_xO_3(x=0, 0.1, 0.3, 0.5)의 환원 반응성에 대한 연구
황호순,이규석,박일현 성균관대학교 기초과학연구소 1993 論文集 Vol.44 No.1
B site substituted mixed oxides LaCo_(1-x)Cu_xO_3(X=0, 0.1, 0.3, 0.5) were prepared by citrate sol-gel method in air, 850℃. By the thermal gravimetric analysis(TGA) and XRD analysis all of these oxides were single phase perovskite of rhombohedral structures. A as the amount of substituent increases, the amount of oxygen decreases and the lattice volume increases. Oxygen stoichiometry and lattice parameters of these oxides are as follows. LoCoO_3.0(a=5.44, c=13.10 Å), LaCo_0.9Cu_0.1O_3.0(a=5.44, c=13.2 Å), LaCo_0.7Cu_0.3O_2.92(a=5.46, c=13.14 Å), LaCo_0.5Cu_0.5O-2.84(a=5.45, c=13.27Å) According to the TPR results, LaCoO_3 and LaCo_0.5Cu_0.5O_2.84 undergo two-stage reduction stages, but LaCo_0.9Cu_0.1O_3.0 and LcCo_0.7Cu_0.3O_2.92 undergo three stages. The first reduction reaction of these oxides is one electron reduction reaction(oxygen 0.5mole). Reoxidated oxide in air at 1000℃, LaCoO_2.94 shows oxygen defect but the TPR result is similar to that of as-prepared oxide. By the reaction kinetics, the activation energy of LaCo_09.Cu_0.1O_3 is found to be the lowest value among those of the substituted oxides LaCo_(1-x)Cu_xO_(3-y).

During the last decade, origin and destination survey has been recognized in Korea as on of the most important basic data concerning transportiation planning. Seoul city conducted the O/D survey three times during this period, 1970, 1973 and 1977 respectively. Commissioned by the city government, Korea Institute of Technology(KIST) carried out all three surveys. However, it is suspected that person trip data from these survey somewhat lacks the reliability partly due to the unsatisfactory survey design. And a comparative analysis of these data with similar data from other countries has not been made. The purpose of this study is to point out the necessity of improving the future O/D survey techniques by comparing trip data of Seoul with those of Tokyo and Hiroshima. In this way our existing trip data would be in aproper perspective. The finding of the studu are as follows. 1) The trip-generating rate (number of trips made by person) in Seoul is still relatively low and it will be increased sharply with rising living-standards, passenger car ownerships and especially with changes in the social wtructure of Seoul. 2) The existing person-trip data by purpose seems skewed due to the oversampling of households with students. Thus trips to school are over-represented and consequently all other purpose trips are underrepuresented. 3) The composition ratio of trips by walking is extremely low camparing with those of Tokyo and Hiroshima. The cause of this is suspected that the improper explanation made by the survey interviewer and interviewee's general tendency of regarding trips by walk as no trips. 4) With the completion of Seoul subway No.2 to 4 by 1985, the picture of modal split in seoul will change dramatically. Current heavy reliance on bus and taxi system, 68.1% in 1977, will be less than 28% by estimation by 1985. A transportation policy addressing phasing down of bus and taxi system be devised in advance.
