Purpose : To compare cephalometric measurement between measuring methods in digital and conventional lateral cephalometric radiograph. Materials and Methods : Twenty digital and conventional lateral cephalometric radiographs were selected. In digital group, cephalometric measurements were performed manually using hardcopies and automatically using VCeph^(TM) program on the monitor. In conventional group, the same measurements were performed manually on conventional films, and for automatic measurement conventional films were digitized by scanner. All measurements were performed twice by 4 observers, and 24 cephalometric variables were calculated and the time spent for each measurement was recorded. The differences in measurements data and the time spent for each measurement were compared within each group. Intra-observer and inter-observer comparisons were performed. Results : In both groups, no statistically significant difference between manual and automatic measurements was observed and most of the variables didn’t show statistically significant differences between methods. The observer with less experience tended to show statistically significant differences of measurements between methods, and differences from other observers. The differences of measurements between methods in digital group were lesser than those of conventional group with statistical significance in 8 variables out of 24. With automatic method and in digital group, the spent time was shorter. Conclusion : With direct digital radiograph, automatic method using manually idenitified landmarks can be preferable in cephalometric analysis.

Purpose: This study was to prepare the basic data for prevention of colo-rectal cancer and protection against its spread. Method: The subjects for the study were 204 patients with colo-rectal cancer from the G.S. wards of five general hospitals in Busan for the period of June 1 to September 1, 2001. The instrument used was questionaire which was developed by Junho Shin(1995). The data was analyzed by descriptive statistics, McNemar test, x^2 test, paired t-test, and ANOVA. Result: 1. 57% of the studied subjects were male, 42.7% were more than 60 years old, 54.9% were of standard physique, 49.5% were the Buddhists, 50.5% were the middle or high school graduates. 83.8% were city dwellers, 48% were jobless, 69.6% had no-history of alimentary disease, 44.1% had no-family history of cancer, 82.8% were married. 2. Constipation (x^2=36.45, p=0.0001) in clients showed a significant positive association for the pre-diagnosed, but diarrhea(x^2=3.947, p=0.047)showed a significant positive association for the post-diagnosed. The preference for high seasonings(t=6.23, p=0.0001) and animal fat (t=8.35, p=0.0001) was higher significantly in the pre-diagnosed, but physical activities(x^²=30.22, p=0.0001), an eutrophic or tonic medicine(x^2=30.22, p=0.0001), was of and vegetables(t=-6.20, p=0.0001) was higher significantly in the post-diagnosed. 3. There were significant differences in the life style of the pre-diagnosed according to the general characteristics except religion. Conclusion: Results of the above study reveal we should be very sensitive to the change of defecation styles and consider the necessity of improving life styles as regards eating habits. When an education program is developed, the general characteristics of the subjects need to be considered.

본 연구의 목적은 glucose leakage test를 이용하여 soft chelating irrigation이 근관 충전의 sealing ability에 미치는 영향을 평가하는 것이다. 발치된 45개의 단근치를 수집하여 치관부를 잘라내 치근이 총 13mm가 되게 하였다. 근관은 K3 NiTi 구동 기구를 사용하여 성형하고 #45/.06 taper까지 확대하였다. 3개의 실험군(n=13)과 2개의 대조군(n=3)으로 나누었다. 실험군은 다음의 세척 방법으로 처리하였다. 1군, 2.5% NaOCl로 세척; 2군, 2.5% NaOCl로 세척 후 17% EDTA로 최종 세척; 3군, 2.5% NaOCl과 15% HEBP 혼합 용액으로 세척, 근관은 gutta-percha와 AH Plus를 사용하여 측방가압으로 충전하였다. , 습도 100%에서 7일 동안 보관하고 glucose leakage model을 이용하여 치관부로부터 치근부 방향의 미세누출을 정량화하였다. 1, 4, 7, 14, 21, 28일 째 누출된 glucose의 농도를 spectrophotometry로 측정하였다. 분석 결과 모든 실험군에서 실험 기간 동안 누출이 증가하는 경향이 있었다. HEBP처리군은 실험 기간 동안 EDTA처리군과 유의한 차이를 보이지 않았다. HEBP처리군은 21일 이후부터 도말층으로 덮인 NaOCl처리군에 비해 유의하게 낮은 누출을 보였다. HEBP로 처리된 상아질은 EDTA로 처리된 상아질과 비슷한 양상의 폐쇄를 보였으나 도말층이 남아있는 상아질보다는 우수한 sealing ability를 나타냈다. 그러므로 약한 킬레이트제인 HEBP는 EDTA의 대안이 될 수 있을 것이다. The purpose of this study was to evaluate the effect of soft chelating irrigant on the sealing ability of root fillings by using a glucose leakage test. A total of 45 single-rooted teeth were selected for the study. The teeth were decoronated leaving a total length of 13mm. The root canals prepared using K3 NiTi rotary instruments to an apical dimension of size 45(0.06 taper). The specimens were then randomly divided into 3 experimental groups of 13 roots each and 2 control groups of 3 roots each. Specimen in each group were prepared with different irrigation protocols : group 1, 2.5% NaOCl; group 2, 2.5% NaOCl and 17% EDTA: group 3, 2.5% NaOCl and 15% HEBP. The root canals were filled with gutta-percha and AH Plus sealer using lateral condensation. After 7 days in , 100% humidity, the coronal-to-apical microleakage was evaluated quantitatively using a glucose leakage model. The leaked glucose concentration was measured with spectrophotometry at 1, 4, 7, 14, 21 and 28 days. There was a tendency of increase in leakage in all experimental groups during experimental period. HEBP-treated dentin showed no significant difference with EDTA-treated dentin during experimental period. From the 21th day onward, HEBP-treated dentin showed significantly lower leakage than smear-covered dentin. HEBP-treated dentin displayed a similar sealing pattern to EDTA-treated dentin and a better sealing ability than smear-covered dentin. Consequently, a soft chelator(HEBP) could be considered as the possible alternative to EDTA.

In this study, facial pore size of vertical length changing from vertically stretched pore to smaller circular pore was investigated to provide basic data for clinical research center develop in pore size measurement method in the future. Vertical length of skin pore was measured by taking pictures of facial site using Visio Face® 1000D at the time before and after the use of the product with the same indoor lightning condition. Taken pictures are analyzed with the Image Pro Plus v7.0 program to evaluate the vertical length of the pore. As a result of analysis, vertical length of the pore was gradually reduced as 9.23±2.34 pixel before product use, 8.17±1.90 pixel immediately after use, 7.44±1.84 pixel after 3 days, and 6.62±1.75 pixel after 7 days. In addition, the number of pore was also gradually reduced as 120.41±51.56 ea before product use, 62.73±50.48 ea immediately after use, 51.05±44.59 ea after 3 days, and 40.32±38.23 ea after 7 days. These results indicate that vertical length of facial pore were investigated by using Visio Face photo and Image Pro analysis and this measurement method may be applicable to evaluate skin pore research and treatment.

본 연구는 자외선 차단지수(Sun protection Factor, SPF) 측정 시험에서 피험자의 안전을 확보하고 정확한 시험결과를 통해 향후 자외선 조사시험의 기초 데이터 확보 및 연구자료 마련을 목적으로 하였다. 피부유형 기준표에 따라 피험자의 피부유형 Ⅰ, Ⅱ, Ⅲ 형에 해당되는 피험자 395명을 대상으로 하였다. 색차계를 이용하여 피부색을 측정한 뒤 ITA (Individual Typology Angle) 값을 계산하고 그 값이 28 이상인 사람을 대상으로 편안한 자세를 취하도록 하여 자외선을 60 s 간 조사한 후 24 h 뒤 피험자의 홍반 상태를 판정하였다. 전면에 홍반이 나타난 부위에 조사한 UVB의 광량 중 최소량을 최소홍반량(Minimal Erythema Dose, MED)으로 하였다. 통계학적 분석은 Statistical Package for the Social Sciences 프로그램을 사용하였다. 피부 유형이 높아질수록 MED 값이 증가하여 피부색이 어두워질수록 MED가 증가한다는 결과를 얻을 수 있었다. 또한 여성이 남성보다 높은 MED로 여성이 남성보다 어두운 피부유형을 가진 것으로 나타났고, 연령별 MED는 피부타입별 모든 연령대에서 연관성이 없었으나 이 같은 결과를 단정 짓기에는 성별, 연령대별 피험자 수가 적어 통계적 유의성을 뒷받침하는데 한계가 있을 것으로 생각된다. 본 연구를 통해 얻은 피부유형별 MED 측정값은 자외선 차단제를 사용하기 전 MED 값을 예상하여 자외선차단제의 효능 평가 시 비교, 판독을 할 수 있는 기준이 되므로 임상에 안전하게 적용할 수 있는 기초자료로써 유용하게 쓰일 수 있을 것이다. In this study, ultraviolet protection factor (Sun Protection Factor, SPF) was investigated to provide basic data for subject safety and research of ultraviolet (UV) irradiation test in the future. Trial subjects (395 people) of skin type Ⅰ, Ⅱ, and Ⅲ were evaluated according to skin type standard table. After measuring the skin color using a colorimeter, ITA (Individual Typology Angle) value was calculated. Subjects with 28 and above ITA value were positioned comfortably to be UV irradiated for 60 s and erythema was evaluated 24 hours after application. MED (Minimal Erythema Dose) was investigated where the minimal amount of erythema existed among UVB irradiated area. Statistical analysis was investigated using Statistical Package the Social Sciences program. As a result, the darker skin color results in the higher MED value since the higher skin type number results increased MED value and female has higher MED value than male since female has darker skin type than male. There was no relation between MED difference by ages in all different ages. However, it is hard to draw a conclusion as above since the number of subjects were not sufficient to support statistical significance for MED values by different ages. However, MED values by skin types obtained through this study can be used as a standard when MED value is expected to evaluate efficacy of sunscreen product and as basic data for further safety of clinical researches.

Nam, Hyang-Mi,Lim, Suk-Kyung,Kang, Hyun-Mi,Kim, Jae-Myoung,Moon, Jin-San,Jang, Keum-Chan,Joo, Yi-Seok,Kang, Mun-Il,Jung, Suk-Chan AAVLD 2009 Journal of veterinary diagnostic investigation Vol.21 No.5

<P>The aim of this study was to determine the antimicrobial resistance of streptococci isolated from mastitic bovine milk samples. A total of 178 isolates belonging to 6 different Streptococcus species were examined: S. uberis (n = 99), S. bovis (n = 30), S. oralis (n = 24), S. salivarius (n = 13), S. intermedius (n = 7), and S. agalactiae (n = 5). Only 8.9% (16/178) of the isolates were susceptible to all antimicrobial agents tested in this study, and S. agalactiae and S. intermedius isolates were all resistant to at least 1 antimicrobial agent tested. Overall, the most frequently observed resistance was to tetracycline (61.2%), followed by lincomycin (43.2%), gentamycin (35.3%), oxacillin (34.3%), and erythromycin (28.6%). Cephalothin and penicillin were the only antimicrobial agents to which most of the streptococci (>or=92%) were susceptible. Wide differences in the prevalence of resistance are apparent among the individual species: S. salivarius displayed exceptionally high resistance to cephalothin (23.0%) and oxacillin (76.9%) and S. agalactiae (20%) and S. intermedius (14.2%) to penicillin. Streptococcus salivarius and S. agalactiae were all susceptible to erythromycin, but others showed various rates of resistance ranging from 12.5% to 42.8%. Resistance to 3 or more of 7 antimicrobial agents was observed in all species (37.6%, 67/178).</P>

본 연구에서는 연령별 수분함유량, 유분함유량 및 경표피수분함유량에 대한 데이터를 비교 분석함으로써 연령별 피부 특성 차이를 규명하여 향후 화장품 산업개발에 도움을 줄 수 있는 기초자료를 제공하고자 한다. 피험자 남녀 총 638명을 대상으로 볼 부위의 수분함유량, 코 끝 부위의 유분함유량, 볼과 전박부위의 경표피수분손실량을 측정하였으며, Statistical Package for the Social Sciences (version 19.00; SPSS Inc., Chicago, IL, USA) 프로그램을 사용하여 분석하였고 피험자에 대한 정보뿐 아니라 피부 수분함유량, 유분함유량, 경표피수분손실량의 피부 측정치 결과를 평균 ± 표준편차로 나타내었다. 그 결과 볼 부위의 수분함유량은 여성이 남성보다 높았으며, 연령이 높아질수록 수분함유량이 증가하였다. 또한 코 부위의 유분함유량은 남성이 여성보다 높았으며 연령이 낮아질수록 유분함유량이 증가하였다. 볼 부위의 경표피손실량은 여성이 남성보다 높은 반면, 전박 부위의 경표피손실량은 남성이 여성보다 높았다. 이상의 연구 결과로 추후 화장품 산업에서 연령별, 성별 기초화장품 개발 등에 도움을 줄 수 있는 기초자료로 활용될 수 있을 것이라 사료된다. In this study, water content, sebum content, and transepidermal water content were investigated to provide basic data for the future cosmetics industry as comparing the skin characteristics of different ages. Water content of cheek area, sebum content of nose area, and transepidermal water loss (TEWL) of cheek and forearm of trial subjects (total 638 people of both male and female) were measured. Data were analyzed using Statistical Package for the Social Sciences program (version 19.00; SPSS Inc., Chicago, IL, USA). Water content, sebum content, and TEWL of skin were measured as mean ± standard deviation. As a result, water content of cheek from female was higher than male and the water content increased with the older ages. However, sebum content of nose from male was higher than female and the sebum content increased with the younger ages. TEWL of cheek from female was higher than male, but TEWL of forearm from male was higher than female. Therefore, these results can be used as basic data in the development of future cosmetics for different ages and genders.
