百濟의 遼西經略에 對하여

金庠基(Kim Sang-kee) 백산학회 1967 白山學報 Vol.- No.3

Sung-shu(宋書)gives an account for the first time that Bekje (百濟) brought Liao-Hsi(遼西)area (an area west of Liao-ho (遼河) under its rule and established there its own administrative districts with Chinp’ing Hsien(晋平縣), Chin-p’ing Chun(晋平郡)as the center. This occupation seems to have been realized toward the end of the thirteenth king Kŭnch’oko-wang’s (近育古王) reign. It was in his time that Bekje was powerful enough to emulate with Kokuryo(高句麗), and eventually after repeated battles in the Debang (帶方) (now, Hwanghe-do 黃海道) area, its army killed Kokuryŏ’s sixteenth king Kokukwŏn-wang(故國原王)below the Pyongyang(平壤) Castle. Before during the era of its fifteenth king Mich’ŏn-wang 美川王, Kokuryŏ occupied the Liao-Tung(遼東)area(or the Liaotung Peninsula) and evacuated from the area thereafter with no fear of threat from the north. Thus it is probable that by advancing into Liao-Hsi area by sea, Bekje as a naval power attempted to check Kokuryŏ’s southward force. The reason why Kokuryŏ and Bekje could so easily seize Liao-Tung and Liao-Hsi areas respectively is that in the continent the so-called Wu-hu Shih-liu-kuo (五胡十六國) were at odds with each other in a chaotic situation, and there was no force that could reach their eastern frontier. Later the Liao-Hsi area occupied by Bekje was attacked by Hou-wei(後魏)(Pei-wei 北魏), and there was a time in the era of the twenty-fourth king Tongsong-wang(東城王)when Bekje defeated a large force of Hou-wei, and according to a record in Nan-ch’i-shu(南齊書), it requested the Ch’i(齊)Dynasty (of Nan-ch’ao 南朝), which was then against Hou-wei, to confer a peerage on the victorious general named Sabŏbmyŏng(沙法名). No historical record is available as to how Bekje’s power changed in Liao-Hsi area thereafter, but from the fact that Hou-wei finally unified areas north of the Yangtze River, we can infer that Bekje’s influence in Liao-Hsi area was crippled by Hou-wei, Bekje’s occupation of Liao-Hsi area is recorded mostly in Sung-shu and Nan-Ch’i-shu. Compiled by Shên Yüeh(沈約), who wrote history for both the Sung and Ch’i Dynasties and was an official in the Liang(梁) Dynasty, Sung-shu was published in the sixth year of Ch’i’s King Wu(武)(A.D.488). And Hsiao Tzŭ-hsien(蕭子顯), compiler of Nan-ch’i shu, was a member of Nanch’i’s(南齊)royal household, and upon the fall of the dynasty, he went to serve King Wu of the Liang (梁) Dynasty and presented him with the book. As the two books were compiled by witnesses to the days, their reliability is unquestionable.

Background/Aims: The prevalence of hepatitis C virus (HCV) infection in Korea exhibits significant geographic variation, with it being higher in Busan and Jeonam than in other areas. The reason for this intranational geographic difference was investigated in this study by conducting a comparative analysis of the risk factors related to HCV infection among three geographic areas: the capital (Seoul), Busan, and the province of Jeolla. Methods: In total, 990 patients with chronic HCV infection were prospectively enrolled at 5 university hospitals located in Seoul (n=374), Busan (n=264), and Jeolla (n=352). A standardized questionnaire survey on the risk factors for HCV infection was administered to these three groups of patients, and a comparative analysis of the findings was performed. Results: The analysis revealed significant regional differences in exposure to the risk factors of HCV infection. By comparison with patients in Seoul as a control group in the multivariate analysis, patients in Busan had significantly more experience of invasive medical procedures, acupuncture, cosmetic procedures, and multiple sex partners. In contrast, patients in Jeolla were significantly older, and they had a higher prevalence of hepatocellular carcinoma, a lower prevalence of multiple sex partners, and had experienced fewer invasive procedures. Conclusions: There was a significant geographic difference in the exposure to potential risk factors of HCV infection between patients from the three studied regions. This may explain the regional variation of the prevalence of HCV infection in Korea, and should be taken into account when planning strategies for the prevention and management of HCV infection.

경성여자의학전문학교 창립의 주체였던 김탁원,길정희부부는 왜 실제 설립 과정에서 제외되었는가?

Chosun (a.k.a. Keijo) Women``s Medical Training Institute was founded in 1928 as a joint effort between an American missionary physician named Dr. Rosetta Sherwood Hall and one of Korea’s first female physicians, Dr. Kil Chung-Hee. In 1932, in anticipation of her retirement, Dr. Hall transferred full responsibility for the Institute to Dr. Kil and her husband Dr. Kim Taik-Won, a neuropsychiatrist. Unfortunately, following Dr. Hall``s departure to America in 1933, funding from Dr. Hall’s missionary society was discontinued. This prompted an evacuation of the Institute’s lecture halls and teaching laboratories. As a result of this change in finances, the Institute’s operations were transported to, and maintained exclusively at, Drs. Kim and Kil``s private residence. During this interim period, the institute was sustained financially by this husband and wife team. In addition to these new found financial difficulties, there were ongoing political hardships. In an effort to alleviate these various difficulties, the couple decided to pursue the task of upgrading the Institute to a standard medical college. As a first step toward this goal, in 1934, the couple established a foundation for the “creation of a women``s medical college”. This undertaking (i.e., the creation of a medical college) required a large amount of funding. Therefore, the couple became actively engaged in the solicitation of funding for this purpose. In 1937, an education philanthropist named Mr. Kim Chong-Ik agreed to donate substantial funds for the purpose of establishing the women’s medical college. As fate would have it, however, / 49 he unexpectedly contracted dysentery and died suddenly. The application for the creation of a women``s medical college was filed and approved in 1938 by the Japanese Governor-General. Thus, the first class of students in the newly created medical college was enrolled on May 1, 1938. Curiously, however, neither Dr. Kim nor Dr. Kil was named in the charter. Although one could presuppose various reasons to explain how this omission occurred, there is one undeniable aspect of history that makes clear and cogent sense in this regard. It is now known that Dr. Kim was a leading activist for Korean independence from Japan during the 1920’s and 1930’s. He was regarded as an agitator by the Japanese occupation government and viewed as an undesirable, rebellious, anti-Japanese element. The South Korean government, in recognition of his heroic deeds during that period of Japanese occupation, posthumously awarded the Ae-Jok Jan(humanitarian award) to Dr. Kim Taik-Won on August 15, 2007. On July 4, 2008, his remains were subsequently transferred, along with his professional partner and wife Dr. Kil Chung-Hee, to the Korean National Cemetery in Daejon, South Korea. If one considers the political climate that existed in Korea in the late 1930’s under Japanese occupation, it stands to reason that any medical college application that included an anti-Japanese activist such as Kim Taik-Won would be doomed to fail. I believe that the absence of Drs. Kim Taik-Won and Kil Chung-Hee’s names from the medical college charter was a rational, politically motivated act of omission.

Evaluation of the Acromioclavicular Joint Morphology for Minimizing Subacromial Erosion after Surgical Fixation of the Joint Using a Clavicular Hook Plate

Sung-Jae Kim,Young-Moon Kee,Dong-Hyuck Park,Young-Il Ko,Bong-Gun Lee 대한견주관절의학회 2018 대한견주관절의학회지 Vol.21 No.3

Background: Subacromial erosion remains a major concern after surgical fixation of acromioclavicular (AC) joint using a clavicular hook plate. To minimize postoperative subacromial erosion, we investigated the structural relationship between distal clavicle and acromion around the AC joint by considering the surgical fixation of the joint using the hook plate technique. Methods: Computed tomography scans of 101 AC joints without any inherent pathology were analyzed. The angle between the distal clavicle and acromion around the AC joint (AC angle), depth of the acromion, differences in height between distal clavicle and acromion(AC height difference), and thickness of distal clavicle and acromion at the AC joint were measured. Descriptive statistics were calculated for each anatomical parameter, and all results were compared between gender groups. Results: The mean AC angle was 17.1°(range, -8.0° to 39.0°), and the mean AC height difference was 3.5 mm (range, -0.7 to 8.7 mm). Both factors showed very high variability (coefficients of variation=62.6% and 46.6%, respectively). The mean AC angle was significantly higher in the female gender than in the male gender (19.8° vs. 13.8°, p=0.048). The mean acromion thickness and distal clavicular thickness were both significantly thinner in the female group than in the male group (p<0.001). Conclusions: Taken together, we believe our results might be helpful in minimizing postoperative subacromial erosion when performing surgical fixation of the AC joint using the hook plate, and be valuable in improving future design of the hook plate.

In this paper, we propose a novel paradigm to regulate the cooperation of a multiple mobile robot system. It defines relationships between robots in a similar way that relationships between humans are characterized in our societies. The degree of relationships can be changed over time. For example, it can be increased by the number of cooperation between robots. The robots autonomously determine whom to help based on their relationship. In this work, it is used particularly for regulating the cooperation of robots in an effective way. The overall performance of the proposed paradigm was tested by several experiments using a multi-robot system. The system was assigned to complete a task, which is clearing boxes in a pre-defined area. A couple of other models of cooperation without considering relationship were implemented. It was found that the execution time was reduced by 12 % with the proposed model compared with those of non-relational cooperation model.

The purpose of this study was to develop a $CO_2$ emission factor for refuse plastic fuel (RPF) combustion facilities, and calculate the $CO_2$ emissions from these facilities. The $CO_2$ reduction from using these facilities was analyzed by comparing $CO_2$ emission to facilities using fossil fuels. The average $CO_2$ emission factor from RPF combustion facilities was 59.7 Mg $CO_2$/TJ. In addition, fossil fuel and RPF use were compared using net calorific value (NCV). Domestic RPF consumption in 2011 was 240,000 Mg/yr, which was compared to fossil fuels using NCV. B-C oil use, which has the same NCV, was equal to RPF use. In contrast, bituminous and anthracite were estimated at 369,231 Mg/yr and 355,556 Mg/yr, respectively. In addition, the reduction in $CO_2$ emissions due to the alternative fuel was analyzed. $CO_2$ emissions were reduced by more than 350 Mg $CO_2$/yr compared to bituminous and anthracite. We confirmed that using RPF, an alternative fuel, can reduce $CO_2$ emissions.

Objectives: The purpose of this in vivo study was to investigate the microbial diversity in symptomatic and asymptomatic canals with primary endodontic infections by using GS FLX Titanium pyrosequencing. Materials and Methods: Sequencing was performed on 6 teeth (symptomatic, n = 3; asymptomatic, n = 3) with primary endodontic infections. Amplicons from hypervariable region of the small-subunit ribosomal RNA gene were generated by polymerized chain reaction (PCR), and sequenced by means of the GS FLX Titanium pyrosequencing. Results: On average, 10,639 and 45,455 16S rRNA sequences for asymptomatic and symptomatic teeth were obtained, respectively. Based on Ribosomal Database Project Classifier analysis, pyrosequencing identified the 141 bacterial genera in 13 phyla. The vast majority of sequences belonged to one of the seven phyla: Actinobacteria, Bacteroidetes, Firmicutes, Fusobacteria, Proteobacteria, Spirochetes, and Synergistetes. In genus level, Pyramidobacter, Streptococcus, and Leptotrichia constituted about 50% of microbial profile in asymptomatic teeth, whereas Neisseria, Propionibacterium, and Tessaracoccus were frequently found in symptomatic teeth (69%). Grouping the sequences in operational taxonomic units (3%) yielded 450 and 1,997 species level phylotypes in asymptomatic and symptomatic teeth, respectively. The total bacteria counts were significantly higher in symptomatic teeth than that of asymptomatic teeth (p < 0.05). Conclusions: GS FLX Titanium pyrosequencing could reveal a previously unidentified high bacterial diversity in primary endodontic infections. 연구목적: 본 연구는 원발성 치근단 치주염(primary apical periodontitis)을 갖는 치아에서 임상증상 유무에 따른 미생물 군집의 차이를 GS FLX Titanium pyrosequencing을 이용하여 species level까지 분석하였다. 연구 재료 및 방법: 원발성 치근단 치주염을 갖는 6개의 표본에서 pysequencing을 시행하였다. 중합효소 연쇄반응(PCR)에 의해 얻어진 small-subunit ribosomal RNA의 초가변 영역(hypervariable region)의 amplicon을 이용하여 GS FLX Titanium pyrosequencing 을 시행하였다. 결과: 평균적으로 무증상군 및 증상군에서 각각 10,639 및 45,455개의 16S rRNA sequence을 얻었으며 평균길이는 440bases였다. Ribosomal Database Project Classifier을 이용한 분석결과 142종의 genera 및 13종의 phylum 수준에서 의 세균종을 검출하였다. 검출된 13개의 phyla 가운데 Actinobacteria, Bacteroidetes, Firmicutes, Fusobacteria, Proteobacteria, Spirochetes, and Synergistetes 종이 상대적으로 호발하였으며, genus 수준에서는 Pyramidobacter, Streptococcus, Leptotrichia이 무증상의 근관의 50%를 차지하였으며, Neisseria, Propionibacterium, Tessaracoccus 균종은 증상이 있는 근관의 69%를 차지하였다. Operational taxonomic units (3%)로 나눈 결과 증상이 없는 치아에서 450개, 증상이 있는 치아에서 1,997개의 species가 발견되었다. 증상이 있는 치아에서 통계적으로 유의성 있게 많은 수의 세균이 검출되었다(p < 0.05). 결론: GS FLX Titanium Pyrosequencing 기법을 통해 원발성 감염근관에서 이전에 검출하지 못했던 다양한 근관내 분포 세균을 검출할 수 있었다.
