Cytotoxic substances in dental calculus and root cementum of periodontally diseased teeth inhibit new attachment and regeneration. The purpose of scaling and root planing is to remove pathologic structures harboring these cytotoxic substances in order to create a biologically acceptable root surface. However, these procedures inevitably leave a non-biocompatible smear layer. Conventionally, the smear layer has been removed with low pH etching agents such as citric acid, phosphoric acid and tetracycline hydrochloride(TC). Lately, a supersaturated neutral pH etching solution of ethylene diamine tetraacetic acid(EDTA) has been found to be as effective as low pH etchants with respect to smear removal and to be superior in exposing root surfaceassociated collagen. The aim of the present study was to determine the effect of root surface treatment using EDTA on the initial attachment of human gingival fibroblasts. 27 human teeth, extracted due to severe periodontitis, were cut into dentin slices after root planing. The specimens were divided into TC group(treated with $50㎎/m{\ell}$ tetracycline-HCl, pH 1.52), EDTA group(treated with 17% EDTA, pH 7.4), and non-treated control group. After sterilization, 5th subcultured human gingival fibroblasts were seeded in each culture well containing a prepared root slice and incubated for 15 min., 60 min., and 4 hours in 5% $CO_2$ incubator at $37^{\circ}C$. At each incubation time, the number of attached fibroblasts were counted on the microphotographs taken at a magnification of x100. The difference of the number of attached cells between groups was statistically analyzed by the ANOVA followed by Duncan test in SPSS/PC+programs. The results were as follows : 1. After incubation for 15 min, the attached cells were significantly more in EDTA group and TC group than non-treated control group(p<0.05), but there was no significance in the difference between EDTA group and TC group(p>0.1). 2. After incubation for 60 min and 4 hours, there was no significant difference in the number of attached cells between all groups(p>0.1). 3. In both EDTA group and TC group, there was no significant difference in the number of attached cells between different incubation(p>0.1). But in control group, the number of attached cells was significantly increased after incubation for 60 min, compared with incubation for 15 min(p<0.05). The above results suggest that root surface treatment using EDTA could enhance the initial attachment of gingival fibroblasts to root surface as effective as tetracycline-HCl.

공학설계수업에서의 PBL 모형 개발 및 효과 분석

김성봉(Kim, Sung-Bong),홍효정(Hong, Hyo-Jeong) 한국산학기술학회 2010 한국산학기술학회논문지 Vol.11 No.11

지식정보화 사회로의 진전이 가속화 되는 21세기에 공학도들에게 창의적 문제해결능력이 무엇보다 강조되고 있는데, 이러한 능력 개발을 위한 접근방식은 다양할 것이다. 본 연구는, 문제중심학습(PBL)이 그러한 접근방식에 있 어 하나의 효과적인 대안으로 인식하고, 기존의 PBL모형에 기초하지만 대학 공학설계수업에 적합하도록 독자적으로 개발하고 그 효과를 수업현장에서 검증해 본 ‘JPBL’ 모형을 소개하는 것을 주목적으로 하였다. 효과분석 결과, JPBL 수업을 받기 전과 후의 수업만족도와 조직몰입도는 통계적으로 유의한 차이가 있었으며, 이러한 양적인 결과는 질적 자료 분석에서도 확인할 수 있었다. 이러한 연구결과에 터해 JPBL 모형 개발의 의미와 한계에 대해 논의하였다. In 21th century moving rapidly up to the knowledge and information society, creative problem-solving abilities are preferentially required to engineers. Though there may be various approaches to develop such abilities, PBL instruction method can be an effective alternative to develop such abilities. Recognizing this, one 'JPBL' model was constructed and introduced in this study. The model was developed independently based general existing PBL models and applied to university students to analyze its effectiveness in the aspect of class satisfaction and organizational commitment. Based on results, the meaning and limitation of the model development were discussed.

청소년의 스트레스 대처 행동과 도박중독과의 관계에서 비합리적 도박신념의 매개효과

김성봉(Sung-Bong Kim),장정임(Jung-Im Jang) 한국산학기술학회 2016 한국산학기술학회논문지 Vol.17 No.4

본 연구의 목적은 청소년의 스트레스 대처 행동(문제중심 대처, 정서중심 대처)이 비합리적 도박신념을 매개로 도박 중독에 미치는 영향을 알아보는데 있었다. 이를 위해 제주지역 고등학생 377명을 대상으로 연구를 진행하였다. 연구가설을 검증하기 위하여 Baron & kenny의 회귀분석 4단계를 거쳐 매개효과를 검증하였고, Sobel Test를 실시하여 매개효과에 대한 유의도를 검증하였다. 연구결과를 요약하면 다음과 같다. 첫째, 문제중심 대처는 도박중독과 부적 상관관계를 보인 반면 정서 중심 대처는 정적 상관관계를 보였다. 둘째, 문제중심 대처와 도박중독과의 관계에서 비합리적 도박신념은 매개역할을 하지 않는 것으로 나타났다. 셋째, 정서중심 대처와 도박중독과의 관계에서 비합리적 도박신념이 완전 매개하는 것으로 나타났다. 결론적으로 정서중심 대처는 스트레스 상황에 놓였을 때 비합리적 도박신념을 높임으로써 도박행동을 강화시키는 것으로 분석되었다. 따라서 청소년들의 스트레스 대처기술을 향상시키고 비합리적 도박신념을 합리적으로 수정하는 프로그램 개발 이 필요하며, 이것이 청소년의 도박중독을 예방할 수 있는 하나의 방안이 될 수 있음을 시사하고 있다. 마지막으로 이러한 결과에 대한 제한점 및 후속 연구의 방향을 제시하였다. This study examined the effects of adolescents' stress coping behavior on gambling addiction using the irrational belief of gambling as a mediating variable. For this, a questionnaire survey was conducted on 377 high school students in Jeju. Data processing analysis of the research was verified by Baron & Kenny's regression analysis in 4 phases and a Sobel Test was done to verify the significance level on the mediation effect. The study results can be summarized as follows. First, while problem-focused coping had a negative (-) correlation with gambling addiction, emotion-focused coping had a positive (+) correlation with gambling addiction. Second, the irrational belief of gambling had no mediating effects on the relationship between problem-focused coping and gambling addiction. Third, the irrational belief of gambling had a full mediating effect on the relationship between emotion-focused coping and gambling addiction. In conclusion, emotion-focused coping under stress situations would enhance the gambling behavior by increasing the irrational belief of gambling. Therefore, it is necessary to develop programs to improve the adolescents' stress coping skills and rationally correct their irrational belief of gambling, which will be helpful in preventing adolescents' gambling addiction. The limitations of this study are discussed together with suggestions for future research.

N/A Dialyzer reuse is an increasingly common practice in the management of end stage renal disease patients on maintenance hemodialysis, but the validity of this form of treatment still remains in question. The performance of dialyzer reuse was studied prospectively in 30 chronic hemodialysis patients using new(n=14) and reused(n=16) membranes. Clearance of solutes, hypoxemia and leukopenia were examined before, during and after hemodialysis. The results were summarized as follows: 1) Membrane clearance of small solutes (urea, creatinine) was maintained over dialyzer reuse. 2) Arterial oxygen tension was significantly lower at 30 minutes after hemodialysis in both new and reused cuprammonium dialyzer, but there was no significant difference between two groups. 3) Leukopenia was noted at 30 minutes after hemodialysis in both new and reused cuprammonium dialyzer group but change in WBC count was significantly lower in reused dialyzer group, 4) Transdialyzer changes in pH, hematocrit and bicarbonate at completion of hemodialysis were similar in both groups.

『竹取物語』硏究

金成俸(Kim, Sung-Bong) 대한일어일문학회 2014 일어일문학 Vol.61 No.-

『Taketori monogatari』is the fantasy novel which primarily details conflicts and negotiations between ‘the moon world’ and ‘human world.’ Hence, the most important thing in studying the literature is to grasp the meaning of ‘the moon’ in the work. This thesis was written based on that perspective. The principal ideas can be summarized as follows. First, the phrase the harvest moon in the work reflects not Japanese ancient tradition but the influence of Chinese culture which is to appreciate the moon in the night. Second, the moon world in the work is more like paradise which was added Shintoism and Taoism to the belief in the pure land. Third, the taboo on staring the moon in the work was not passed down from neither Japanese ancient folk beliefs nor China, but was the reflection of author’s experience of lunar eclipse. Fourth, it is considered that the idea of moon being related to women was not first introduced in the Heian period.

예술교과의 교육과정 주변화와 인지능력으로서의 예술

김성봉 ( Sung Bong Kim ) 한국교육과정학회 2009 교육과정연구 Vol.27 No.4

본 연구는 예술이 정서의 영역이어서 비인지적 활동이라는 전통적 사고에 대해 비판적인 학자들이 적지 않음에 문제의식을 갖고, 예술교과가 학교교육과정에서 주변화된 배경과 예술의 인지적 측면을 살펴보았다. 고찰결과, 예술교과가 주변화된 것은 역사적이면서도 관념적인 측면이 강함을 알 수 있었다. 그리고 예술은 본질적으로 인지적 속성을 지니고 있음을 확인할 수 있었다. 이러한 고찰결과에 터해 학교에서의 예술교과는 재평가되어야 함을 논의하였다. This study inquired into the background of art subjects` marginalization in school curriculum and the cognitive aspects of arts through critical scholars` eyes on traditional perspectives of arts which they said artistic activities were emotional and non-cognitive. After review, it was revealed that the cause of art subjects` marginalization in school curriculum could be strongly attributed to the historical and ideological background and that arts intrinsically contain cognitive properties. Based on the findings, it was discussed that art subjects in school curriculum should be revaluated.
