To improve oral hygiene management, the effects of toothbrush training on general oral hygiene based on the simplified oral hygiene index(S-OHI) and degree of knowledge about toothbrushing were examined. Pre-and post-training changes in the S-OHI (lower score = better oral health status) showed a significant decrease in score in all variables (gender, age, marital status, occupation, and level of education).Pre- and post-training changes in the degree of knowledge about toothbrushing showed a significant increase. Negative correlations between the S-OHI, oral health status, and degree of knowledge about toothbrushing and the S-OHI and the Decayed, Missing, Filled (DMF) index (the better the oral cavity environment, the lower the DMF index) were observed. Positive effects of repeated toothbrush training on the maintenance of healthy oral cavity environment and continuous oral health management were observed, as reflected by the correct toothbrushing-related knowledge and skills.

수평면과 경사면간의 일사수광량 편차의 정규화변량인 과열지수는 산악지형에서 일 최고기온 추정오차를 줄이는데 효과가 있다고 알려져 있다. 하지만 계산의 복잡성 때문에 경사도와 경사방향에 근거한 매개변량인 개방지수를 먼저 계산하고 이를 이용하여 과열지수를 간접적으로 추정하는 방법이 널리 쓰이고 있다. 이러한 개방지수 매개 간접추정법이 우리나라와 같이 복잡한 산악지형에서 일 최고기온 추정에 적합한지를 알아보기 위해 강원도 평창군에 위치한 도암댐 표준유역(면적 $149 km^2$, 표고범위 $651{\sim}1,445m$)을 대상으로 야외실험을 실시하였다. 이 지역의 30m 해상도 수치고도모형으로부터 시험유역의 166,050개 격자점의 개방지수와 과열지수를 계산하였다. 이들 간의 관계를 계절별 최적 회귀모형으로 나타내고 이로부터 매월 15일의 과열지수를 개방지수로부터 추정하였다. 인근 대관령기상대와 비슷한 고도(해발 844m)에 경사방향이 서로 다른 7개 지점을 선정하여 온도계를 설치하고 2006년 6월부터 2007년 2월까지의 기온을 10분 간격으로 측정하였다. 추정오차를 종속변수로, 각 지점의 추정 과열지수를 설명변수로 둔 회귀분석을 실시한 결과 결정계수가 겨울 0.46, 가을 0.24, 여름 0.02로서 직접 계산된 과열지수를 설명변수로 하는 경우(겨울 0.52, 가을 0.37, 여름 0.15)에 비해 신뢰도가 떨어진다는 것을 확인하였다.

본 논문은 SLS의 함유정도를 다르게 한 A(0%), B(1.1%), C(2.2%)의 세가지 실험세치제를 제작하여 구강 내 변화를 50명씩 세 그룹(A, B, C)으로 나누어 실험하였다 본 연구결과 SLS함량에 따른 세치제의 4주간 사용 후 3집단의 치면세균막 검사( PHP )에서 집단간차이가 나타났고 SLS함량이 높을수록 PHP의 지수가 낮아졌다. 또한 간이구강위생지수(OHI-S)에서는 A, B, C 세집단 모두에서 OHI-S 값이 줄었다. 또한 PHP와 OHI-S는 높은 상관성을 보였다. SLS함량에 따른 세치제의 4주간사용 후 3집단의 타액분비량 측정 시 SLS함량이 높아질수록 타액량이 감소하였고, 타액의 점조도 및 pH에는 변화가 없었다. SLS가 구강건조를 유발함을 뒷받침하는 결과로 SLS와 타액의 분비량은 음의 상관관계를 보였다.

The author studied on the Simplified Oral Hygiene Index in the handicapped children, who are housed by several rehabilitation institution age from 3 to 17 year in Seoul area and 439 normal children as a control group. The obtained results are as follows: 1) In the Oral Hygiene Index(OHI), The handicapped children showed remarkable increment compared to normal children(The Index score was 2.00 in cerebral palsy children, 1.94 in poliomyelitis, 1.79 in other's diseased children, in 1.01 in normal children) and the score was increased as age increment. 2) In the OHI of the handicapped children, male was higher than female. 3) Dental calculus deposition in the handicapped children was severe in the lower anterior teeth and least in the upper anterior teeth. 4) Dental calculus Index of the handicapped children was comparatively higher in the region which had higher food debris index. 5) As the conculusion of this study, we found that continuous and active dental enlightenment and treatment for oral health in the handicapped children are necessary.

The present study purposed to prevent oral diseases and to improve oral health in children. For this purpose, we selected 70 cases who are 5~7 years old preschoolers at the kindergarten affiliated to G College in Gyeongsangbukdo, and analyzed the general patterns of oral care and the relation of the patterns with dental plaque and deciduous dental caries in the children. Specifically, we conducted oral examination and applied pit and fissure sealant according to the eruption of deciduous molar and first molar. In addition, we executed the 1st and 2nd tooth brushing instruction (TBI), and surveyed S-OHI and PHP twice. Excluding 14 preschoolers who did not appear in the 2nd survey, we performed the study with 56 preschoolers and drew conclusions as follows. 1. The number of decayed or missed or filled teeth among deciduous teeth was 3 or more in 42.9% of female children, and 46.4% of male children, so male children showed a slightly higher rate. 2. The degree of dental plaque formation was $1.64{\pm}1.22$ among the surveyed children. 3. The oral health index was lower after TBI than before in all the children (P<.001). 4. Change in the oral health index was particularly larger in 7 year old female children (p<.005). 5. The patient hygiene performance index was lower after TBI than before in both the buccal surface and lingual surface of the children (p<.005). 6. The patient hygiene performance index was lower after TBI than before in all of male children's teeth except the right maxillary first deciduous molar (p<.001).

This study is Dental Hygiene Department of G University for comprehensive dental hygiene control and treatment weekly for four weeks from September 16 to October 20, 2010, excluding those who visited for ambulatory treatment of systemic diseases. For the 90 subjects, we performed oral examination, measured Simplified Oral Hygiene Index (S-OHI), Modified Patient Hygiene Performance (PHP-M), and O' Leary Index, and applied comprehensive dental hygiene control. First, as to the change of OHI according to age, the index in the 1st measurement was 3.43 in those under 35 and 3.17 in those aged 35 or older, so it was higher in the younger group, but in the 2nd measurement it was 1.89 in those under 35 and 2.14 in those aged 35 or older, and in the 3rd measurement it was 1.22 in those aged 35 or older, so it was higher in the older group. Second, as to the change of PHP-M according to age, the index in the 1st measurement was 50.35 in those under 35 and 43.16 in those aged 35 or older, soit was higher in the younger group, but in the 2nd measurement it was 31.97 in those under 35 and 28.88 in those aged 35 or older, and in the 3rd measurement it was 21.31 in those aged 35 or older, so it was higher in the older group.

Objective : This study was performed in order to provide basic data for halitosis prevention and establish a device to efficiently eliminate halitosis and to analyze the factors that affect the halitosis. Methods : Oral examination on the Gingival index, CPITN, Tongue Plaque index, and OHI-S as well as halitosis measurement among 293 rural residents. Results : Gingival index was high at mild on female and at moderate on male(p=0.025). Sorting the result by age, mild was 54.1% in the 40s, and moderate was 49.5%, 42.0% and 70.0% each in the 50s, 60s, and the 70s(p=0.005). The need for dental plaque management was 100%. The need for scaling was high with 78.3%, 93.0%, 89.9%, and 90.0% each for the 40s, 50s, 60s, and 70s. The need for complex periodontal treatment was also high with 32.4%, 47.5%, 48.7% and 60.0%, each for the 40s, 50s, 60s, and 70s(p=0.050). The highest bad condition for OHI-S was 69.5%, and good being 18.9%, and very bad being 11.6%. For moderate tongue plaque index was 74.4% as the highest. As the level of education increased, the slight tongue plague was increased, but in contrast, the moderate and higher tongue plague index was decreased(p=0.010). OG under 50ppm was 61.1% on male and OG over 50ppm was 50.9% on female(p=0.041). In OG over 50ppm, CPITN was 52.1% and 41.9% in scaling and complex periodontal treatment group(p=0.018). OHI-S, in bad and very bad condition with OG, over 50ppm, was 48.7% and 46.9%(p=0.019). The higher tongue plague index showed significant amount of increase at OG and EG above 50ppm(p=0.006). $NH_3$, as the tongue plaque index increased, the wider range of distribution was shown(p=0.000). As for the multiple regression analysis result, there have been selected females and tongue plaque index as factors affecting OG. There have been selected age and tongue plaque index as factors affecting EG and there have been selected females as factors affecting on $NH_3$. Conclusions : With the aforementioned results in mind, the status of halitosis among rural residents is considered to bare a close relation with oral environments. we have to focus on correct tooth brushing methods and tongue brushing, with using tongue cleaner to remove fur of tongue plaque. Also, in order to analyze exactly the factors of individual halitosis, we need continuous and systematic study.

본 연구에서는 우리나라의 여름과 겨울철의 이상기온 출현 빈도의 변화와 그에 영향을 미치는 요인과의 관계를 파악하고자 하였다. 우리나라의 대부분 관측 지점에서는 여름철 이상고온 출현 빈도의 증가와 겨울철 이상저온 출현 빈도의 감소 경향이 뚜렷하다. 이러한 이상기온 출현 빈도의 변화는 대기 순환 지수 중 겨울철 이상기온 출현에 영향을 미치는 겨울 몬순 지수와 시베리아 고기압 강도 지수 및 북극 진동 지수, 그리고 여름철 이상저온 출현에 영향을 미치는 오호츠크해 고기압 강도 지수와 북태평양 지수 등의 변화 경향과 유사하다. 이 지수들은 이상기온의 변화에 영향을 미치는 요인 중 최근의 지구 온난화 경향을 반영하며 우리나라 전 지역의 이상기온 출현 빈도와 관계가 뚜렷하다.
