Purpose - This study surveyed real estate financial consumers and financial company staff regarding the components of the financial consumer protection system to seek detailed improvement plans for the Financial Consumer Protection Act. Design/methodology/approach - The Analytic Hierarchy Process (AHP) technique is applied. Findings - Both consumers and staff highly evaluated the importance of the preventive measures in the main classification factors. Regarding the sub-classification factors of preventive measures, consumers emphasized the responsible management of investment staff and financial institutions; however, the staff stressed the principle of effectiveness and efficiency. Regarding the elements of ex-post remedies, consumers answered that fast remedy would have a significant effect. At the same time, staff believed that punitive measures hinder free trading and investment activities. Regarding the sub-sub classification factors of prevention measures, the consumers value responsible management of staff and financial companies, while the staff tend to prefer the importance of the self-regulatory governance. Research implications or Originality - Based on the above results, financial regulatory authorities should find a balance between preventive and ex-post components once focusing on preventative measures. Our paper is one of the first research findings in this field of financial consumer protection system in Korea.

The main aim of this paper is to try understanding the Thought and Poetic world of the Chong Mong-Ju in the ending of Koryo(高麗) dynasty. In the first place I have viewed his career in connection with records of the Po-un's anthology(圃隱文集) and Koryosajeolyo(高麗史節要), Koryosa(高麗史), Dongku'kyojiseungnam(東國與地勝覽). Next I have studied the following four short accounts. Those are how Chong Mong-Ju does learn to Su'ng Ri-Hak(性理學) and What is the influence of Chong's Su'ng-Ri-Hak in the society of the ending of Koryo dynasty and is the Reason that Chong Mong-Ju persist in a Ch'in Myung belief(親明路線) and is the problem that Chong Mong-Ju is snipped because standing in front of the reconstruction of Koryo dynasty, In the last place I have viewed the tranformal Features of the Munijado's poetry(文以載道詩) and the poetry of love one's country(國愛詩) and patriotic poetry(憂國詩) and the poetry of Red Patriot(丹忠詩). This paper owing to like that seeks to great thought and Ch'ung-Ju'1(忠節) of the Chong Mong-Ju in this context.
급성 치수염 및 급성 치근단 농양의 치근관으로부터의 세균 분리 및 동정
이연재,김미광,황호길,국중기 大韓齒科保存學會 2005 Restorative Dentistry & Endodontics Vol.30 No.5
치아우식증 및 치주질환에 이환 여부와 치근단 병소의 존재 유무에 따라 급성 치수염 또는 급성 치근단 농양이라고 진단된 17개 치아의 치관부 치수를 제거하고, 치근에 존재하는 괴사된 치수 및 농양부위의 샘플을 채취하여, 혐기성 상태에서 세균을 배양하고, 이들을 16S rDNA 클로링 및 핵산염기서열결정법으로 종 수준에서 동정하였다. 그 결과 17개의 치근관 감염 병소에서 모두 71개의 세균 군락이 자라났으며, 그 중 계대 배양을 통해서 적응하여 자라난 것이 56 균주였다. 치아우식증에 의한 치근관 감염 병소와 치아우식증이 아닌 다른 원인에 의한 치근관 감염 병소에서 검출되는 세균은 서로 다른 양상을 보였다. 즉, 치아우식증에 의한 치아의 치근관 감염 병소에서 연쇄상구균들이 72.7%(8/11)로 가장 많은 빈도로 검출되었다. 반면에 치아우식증이 없는 치아의 치근관 감염 병소에서는 Actinomyces 속의 균주들이 66.7%로 가장 높은 빈도로 검출되었다. 치근단 병소가 있는 경우의 치근관 감염 병소에는 대체로 혐기성 세균인 Clostridia 아문, Bacteroides 문, Fusobacteria 문의 균주들이 검출되었지만, 치근단 병소가 없는 치아에서는 검출되지 않았다. 반면에 치근단 병소가 없는 치근관 병소에서는 연쇄상구균(60%)과 Actinomyces 속(50%)의 균주들이 높은 빈도로 검출되었다. 본 연구에서는 아직까지 종 수준에서 동정되지 않은 2 균주(ChDC B639 및 ChDC B631)의 Actinomyces 속에 속하는 균주가 분리되었다. 이상의 결과를 종합할 때, 세균배양법에 의한 치수 및 치근단 감염 병소에서는 다양한 세균이 검출되었으며, 이는 치근관 감염이 여러 세균에 의해 발병 및 진행된다는 기존의 연구 결과와 동일함을 알 수 있었다. 또한 본 연구 결과 분리 동정된 균주들은 치근관질환과 이와 관련된 세균간의 역학조사에 중요한 자원으로 이용될 수 있을 것으로 생각된다. The aim of this study was to identify the bacteria isolated from acute endodontic lesions by cell culture and 16S rDNA sequencing. The necrotic pulpal tissue was collected from 17 infected root canals, which were diagnosed as being either an acute pulpitis or acute periapicai abscess. Samples were collected aseptically from the infected pulpal tissue of the infected root canals using a barbed broach and a paper point. The cut barbed broaches and paper points were transferred to an eppendorf tube containing 500 ul of 1 X PBS. The sample solution was briefly mixed and plated onto a BHI- agar plate containing 5% sheep blood. The agar plates were incubated in a 37℃ anaerobic chamber for 7 days. The bacteria growing on the agar plate were identified by 16S rRNA coding gene (rDNA) cloning and sequencing at the species level. Among the 71 colonies grown on the agar plates, 56 strains survived and were identifled. In dental caries involving the root canals, Streptococcus spp. were mainly isolated. Actinomyces, Clostridia, Bacteroides and Fusobacteria were isolated in the periapical lesion without dental caries. Interestingly, two new Actinomγces spp. (ChDC B639 and ChDC B631) were isolated in this study. These results showed that there was diversity among the species in endodontic lesions. This suggests that an endodontic infection is a mixed infection with a polymicrobial etiology. These results may offer the bacteriai strains for pathogenesis studies related to an endodontic infection.

The three ideas of Confucianism, Buddhism, Shen-shienism(Tao-ism) are acknowledged as the mental foundation of our the bothsided (i.e. inside and outside) influence of the Shen-Shien Ideas as compared with the Ideas of Confucianism and Buddhism has not been recogized so much. When faing to the logic of the Korean literary history or the literary ideological study, The research for the Shen-Shien Ideas can never be found or it is most careless even if being so. but it goes without saying that the Taoist Ideas along with the Confucianist and Buddhist Ideas is the Traditional ideas of the Korean people and also it is the Ideas of the important basis even in the structure of their consciousness. This Study has put its aim at the aspect of the thematic development of the Shen-Shien (Taoist) Ideas demonstrated from which it(this study) has localized within the Chinese poetical literature of Koryeo era (AD918∼1392), and at studing the tangible caaracteristic of the occult poetic diction and its connective character of the occult expression (immortal expression). The material of the object of this study as the works written in "Samhansiguigam"(三韓詩龜鑑), "Dangmunseon"(東文選), "Shinjeungdognkikyeojiseungram"(新增東國輿地勝覽), (written phonetically) can be found 352 pieces of the occult chiness poetry works of 83 literary men of Koryeo era, wellselected by the writer. The thematic aspect of each can be separately considered as follows, Intention to the trans-world, self-contentment of the trans-worldly passing, Intergrity of the natural intimacy. In the Korean literary history, the chinese literature of Koryeo era is placed in an important position. The vived Romantics and ideological variety of the chinese poetic literature made the literature of the Koryeo era more fruitful and abundant. In this respect, the systematical study and research for the Shen-Shien (Taoist) literature should be newly debated as a precedent works of the arrangement of our literary history ahd literary idelolgical history.
내시경적 용종 절제술을 시행받은 145례의 위용종에 대한 임상 및 병리학적 연구

내시경 시술의 발달로 위에서 발생되는 여러 종류의 용종 중 크기가 악성일 경우는 외과적 절제술이 시행되고 있고 그 외 대부분의 병변은 내시경적 치료가 가능해졌다. 이런 점에서 저자는 위에서 발생되는 용종의 임상적, 병리학적 특징과 각종 내시경적 용종 절제술의 치료 효과와 안정성을 관찰하고자 하였으며, 내시경적 용종 절제술 후 추적 관찰하여 용종의 재발이나 위암의 발생을 확인하고자 한다. Gastric polyps are narrowly defined as macroscopically localized mucosal elevations composed of epithelial elements. They can be divided into two types : hyperplastic polyp and adenoma. Hyperplastic polyps usually occur in a chronically inflamed mucosa with a mild degree of atrophy and composed of normal-appearing epithelial cells, so hyperplastic polyps rarely become malignant. When dysplasia occurs to the polyps, malignant potential increases. Adenoma is composed of immature cells with varing degrees of dysplasia and its malignant potential is very high. So according to the size and pathologic findings, the therapeutic modalities are variable. And they should be removed for prevention of gastric cancer. We have performed endoscopic polypectomy such as snare polypectomy, strip biopsy or "O"ring ligation in 145 patients from July 1988 to June 1995 and evaluated the clinical characteristics, histopathology of the polyps. Twenty three patients who had had adenoma and had been undergone mucosectomy were followed up endoscopically for 6 to 24 months. The results were as follows : 1.One hundred and forty five patients were enrolled in this study. The ratio of male to female was 0.7:1(59 men, 86 females) and mean age was 50.4 (range: 31-79). The polyps were most frequent in the 6th decades of age. 2.The common clinical symptoms were epigastric discomfortness(41.3%), epigastric pain(29.7%), indigestion(17.9%) and abdominal discomfortness(6.9%). 3.The location of polyps were antrum(47.3%), body(45.0%) and fundus(7.7%). The number of patients with multiple polyps were 16(11.0%) and 139 patients had single polyp. The most frequent size of polyps was 0.5-1.0 cm and the next was 1-2 cm. 4.The gross findings of polyps by Yamada's classification were type II (35.5%), type III (29.6%), type I (21.3%) and type IV(13.6%). On histologic examination, hyperplastic polyps were 68.6% and adenomatous polyps were 23.7%. 5.The methods of polypectomy were mucosectomy in 23 cases(strip biopsy : 18, "O"ring ligation : 5) and snare polypectomy in 122 patients. If adenomatous polyps were reseated incompletely, we applied the laser therapy. When snare polypectomy could not be performed, strip biopsy was done. The effectiveness and rate of complications of mucosectomy was not different from that of snare polypectomy. 6.The most frequent complication of polypectomy was epigastric pain(23.4%) and the next was bleeding(14.5%). We could manage epigastric pain with medical therapy. The bleeding was controlled with Nd : Yac laser in five cases, with hypertonic saline-epinephrine injection therapy in five cases and with conventional medical therapy in 11 cases. 7.Among the patients with adenomatous polyps or dysplasia, we followed up 23 cases for 6 to 24 months (mean: 16 mon). There was no recurrence, but in one case gastric carcinoma was detected on other site. In the patients wish gastric polyp, polypectomy should be performed for precise diagnosis and treatment and the methods of polypectomy are taken according to their size and morphologies. Polypectomy is an effective preventive therapy for gastric cancer with low procedural complications.
