To improve effective curriculum of preventive dentistry instruction at dental school, the authors developed the evaluation questionnaire of ``preventive dentistry`` subject in the sophomore class. 252 dental students of Chosun University responded to 36 items with a 5-point-Likert response format after the close of a school term at year 2007, 2008 and 2010. The questionnaires were about general feature of instruction, content of instruction, loads of task, attitude of students to the instruction and the practice exercise. The evaluation was performed at the end of final term periods from 2007, 2008, 2010. The results were as follows. 1. The respondents were generally satisfied with general processing or instruction and contents of preventive dentistry instruction. 2. The respondents took a relatively negative view of attitude of themselves on instruction. 3. More provocative instruction is needed in preventive dentistry instruction and practice. 4. To improve preventive dentistry instruction, development of problem-based learning package at dental schools could be helpful.

Objectives. Toothbrushing is the most fundamental self-help oral care, essential for the removal of dental plaque and food debris which can lead to caries or periodontal diseases. In order for patients to effectively select ideal toothbrush and maintain oral health, this study investigated the efficacy of different toothbrushes available on the market in the removal of dental plaque. Methods. A total of 156 pieces, from each of the three different types of standard manual toothbrushes and three slim-bristle type brushes for adults were randomly selected to be used as experiment units. The bristles of the different brushes were analyzed through a number of different processes. Data analysis was performed with Kruskal Wallis test and Man-Whitney`s U-test, Multiple linear regression at the significance level of alph=0.05. Results. The average surface area from which the artificial dental plaque was removed using the standard manual toothbrushes was 116.41 mm2 and using the slim bristle toothbrushes it was 121.82 mm2. The average buccal surface area from which the artificial dental plaque was removed using the standard manual toothbrushes was 86.93 mm2, and 88.11 mm2 using the slim bristle the slim bristle toothbrushes. The average dental sub-gingival area from which the artificial dental plaque was removed using the standard manual toothbrushes was 4.95 mm2 and 5.32 mm2 for the slim bristle toothbrushes. The average proximal surface area from which artificial dental plaque was removed using the standard manual toothbrushes was 24.79 mm2, and 28.38 mm2 for slim bristle ones. A statistically significant difference between the standard manual toothbrushes and the slim bristle was detected in the proximal surface (p<0.05). For the group consisting of the standard manual toothbrush, It was found that the smaller the difference in the length of implant brush, the greater the amount of plaque that was removed (p<0.05). Conclusions. According to the findings of the study, the factors influencing effective toothbrushing and brush designed indicate a need for further studies.

This study aims not only to present underserved areas with regard to national health screening in Gangwon province using GIS but also to identify factors associated with the participation rate of both national health screening and cancer screening. We used both Statistics Korea and United GIS data. The cost weight distance tool was performed to find underserved areas for both health screening and cancer screening. To analyze factors associated with the participation rate in each health screening, population ratio over 40 years old, income, health level, region(urban/rural) and vulnerability area index(VAI), i.e., underserved area rate in which a total elapsed time to the health screening institution is over 30 minutes, were used for dependent variables. Tobit regression model was performed using STATA 11.0. The VAI for health screening was the highest in the Samcheok-si(15.7%), followed by Inje-gun(18.8%), Youngwol-gun (19.7%), Hwacheon-gun(22.3%), etc. The VAI for cancer screening was the highest in Hongcheon-gun(16.7%), followed by Inje-gun(18.6%), Inje-gun(18.6%), Youngwol-gun(20.9%), Samcheok-si(22.2%), etc. As a result, there was no statistically significant variables to affect the participation rate for health screening. On the other hand, the participation rate for cancer screening was influenced by the VAI(-), region(-), health level(+), income(+) and population ratio over 40 years old(+). To better attain the national health screening rates, GIS technique could be an alternative for policy-makers to find underserved areas for national health screenings.

효소에 의한 옥수수 단백가수분해물의 천연항균제로서의 이용가능성을 조사하기 위하여 zein 단백질에 단백 가수분해 효소를 작용시켜 얻어진 가수분해물의 항균활성을 측정하고 membrane filter로 한외 여과하여 항균활성이 가장 높은 분획을 HPLC로 분취한 후 항균활성을 측정하고 MIC, 각종 세균에 대한 생육저해농도를 측정하여 다음과 같은 결과를 얻었다. Zein 단백질에 6종의 단백분해효소를 작용시켜 제조한 가수분해물 중 pepsin으로 작용시킨 것이 항균활성이 가장 높았다. Membrane filter에 의하여 여과한 가수분해물의 항균활성은 M.W. 10,000~30,000에서 가장 높았으며 121℃에서 10분간 처리하여도 항균활성에 변화가 없는 열안정성이 매우 높았고 MIC는 2.5 ㎎/mL이었다. HPLC로 분리한 항균성 peptide의 N-말단 아미노산 조성은 leucine, glutamic acid, proline, phenylalanine, aspartic acid, argenine 순이었다. 분자량 10,000~30,000의 가수분해 동결 건조물을 3 ㎎/mL 농도로 nutrient broth 배지에 첨가하고 37℃에서 배양하였을 때 크게 생육이 저해되었다. A study was carried out to produce antimicrobial peptides from zein treated with proteases of six kinds. Among the proteases of six kinds, zein hydrolysate treated with pepsin showed the highest antimicrobial activity. The zein hydrolysate with pepsin was fractionated with membrane filter (30,000 10,000 and 3,000 molecular weight cut-off) and antimicrobial activity was measured for each fractions. Antimicrobial activity appeared greatly in the fraction below 3,000 (molecular weight cut-off). The fraction was re-fractionated by HPLC and substances of two peaks collected as a sample to measure antimicrobial activity. All of both peaks showed the antimicrobial activity but 1st peak exhibited a consistently higher antimicrobial activity than 2nd peak. Minimum inhibitory concentrations (MIC) were between 2.5 and 3.0 ㎎/mL. The peptide was heat-stable since antimicrobial activity was maintained after treated with heat for 20 min at 121℃. N-terminal amino acid sequence of peptide fractionated by HPLC was leucine, glutamic acid, proline, phenylalanine, aspartic acid and argenine. These results indicated that peptide isolated from zein hydrosate with pepsin can use as a natural preservative ingredient in food industry.

Thromboembolism is one of the common complications in nephrotic syndrome. The incidence of renal vein thrombosis in the setting of nephrotic syndrome varies from 5% to 62%. Membranous glomerulonephritis (MGN) has been rarely manifested as inferior vena cava (IVC) and/or renal vein thrombosis. We report a case of acute IVC and left renal vein thrombosis as initial manifestation of MGN. The renal vein thrombosis was successfully treated with systemic thrombolysis with temporary IVC filter insertion. After 4 months, MGN was diagnosed by renal biopsy.
