Purpose : To investigate the validity of digital image processing on panoramic radiographs in estimating bone quality before endosseous dental implant installation by correlating bone quality in radiographic images with clinical bone quality classification. Materials and Methods : An experienced surgeon assessed and classified bone quality for implant sites with tactile sensation at the time of implant placement. Including fractal dimension eighteen morphologic features of trabecular pattern were examined in each anatomical sites on panoramic radiographs. Finally bone quality of 67 implant sites were evaluated in 42 patients. Results : Pearson correlation analysis showed that three morphologic parameters had weak linear negative correlation with clinical bone quality classification showing correlation coefficients of -0.276, -0.280, and -0.289, respectively (p<0.05). And other three morphologic parameters had obvious linear negative correlation with clinical bone quality classification showing correlation coefficients of -0.346, -0.488, and -0.343 respectively (p<0.05). Fractal dimension also had a linear correlation with clinical bone quality classification with correlation coefficients -0.506 significantly (p<0.05). Conclusion : This study suggests that fractal and morphometric analysis using digital panoramic radiographs can be used to evaluate bone quality for implant recipient sites.

This paper diagnoses the cause of ecological crisis human beings encounter at present, looks into the ecological viewpoint as an alternative, and discusses the educational task to overcome the present crisis. First, this paper looked into the ecologists' diagnosis of the cause of ecological crisis, focusing on the problem of western christian viewpoint of nature, western dualistic epistemology, and the blind faith in the progress. Second. the discussion of ecological standpoint to overcome the ecological crisis included "deep ecology" and Bookchin's "social ecology". Third, on the basis of these standpoints, the task of new eco-ethical education was suggested. As a result, this paper insisted the urgency to internalize the ethics of responsibility for the life-giving of the whole ecology related to one's life by making individuals and community turn their recognition for the solution of the ecological problems and produce the proenvironmental activity-orientedness.

In order to clarify how the treadmill program influences the blood pressure, serum lipids, and cardiopulmonary function of the hypertensive adult, total 34 subjects-26 male subjects and 8 female subjects- in an age group of 30-65 year joined in a program of treadmill exercise which was carried out for 12 weeks sequentially. The intensity of exercise given to the subjects was within 50-80% of their maximun oxygen uptake, and they had exercise for 20-40 minutes a day which was executed for 5 days a week. And in order to find out any difference or change happening for the application of the program to the subjects, blood pressure, physical composition or structure, serum lipids, metabolism, and cardiopulmonary function were checked before and after exercise and compared with reference to the changes of blood pressure, heart rate, and oxygen uptake while the subjects were taking exercise. And those data were reviewed in terms of a male group and female group and a total group which includes both male and female subjects. Also the data were reviewed in an age group of less than 50 years and another age group of more than 50 years. And additionally, the data were reviewed in three groups concerning systolic blood pressure; a group whose systolic blood pressure decreased by 0-9 mmHg, another group whose systolic blood pressure decreased by 10-19 mmHg, and another group whose systolic blood pressure decreased more than 20 mmHg. And also they were reviewed in three groups regarding diastolic blood pressure; a group whose diastolic blood pressure decreased by 0-5 mmHg, and another group whose diastolic blood pressure decreased by 6-10 mmHg, and another group whose diastolic blood pressure decreased more than 11 mmHg. In the result of such a study, findings are as follows : 1.It appeared that systolic pressure and diastolic pressure in a stable condition after the execution of the program significantly decreased(p<0.001) in the male group and the total group, with also decreased heart rate showing as well in these groups. 2.It appeared that forced vital capacity(FVC), forced expiratory volume for 1 second percent(FEV1), and maximum voluntary ventilation(MVV) after the execution of the program significantly increased (p<0.05, p<0.01) in the male group and the total group, and however only maximum voluntary ventilation increased in the female group. Regarding age, FEV1 increased more in the age group of less than 50 years than in the age group of more than 50 years. 3.Body weight, persent body fat, and fat body weight decreased in all the groups-the male group, female group, and total group since the execution of exercise, and body fluids incresed only in the male group and total group. Regarding age, persent body fat decreased more in the male group whose age is less than 50 years and in the female group whose age is more than 50 years than in other groups. Regarding the decrease rate of blood pressure, the group in that systolic blood pressure decreased more than 20 mmHg in male body fat rate and the group in that diastolic blood pressure decreased more than 11 mmHg showed more decrease rare of blood pressure than other groups. 4.Total cholesterol(TCH), low density lipids protein(LDL), ratio of total cholesterol to high density lipids protein and triglycerides(TG) decreased in all the groups- the male group, female group and total group since the execution of exercise, however high density lipids protein increasing. Regarding age, total cholesterol decreased more in both the male and female groups whose age in under 50 years than both the male and female group whose age is above 50 years. And triglycerides decreased more in the female group whose age is under 50 than in the female group whose age is above 50. Regarding the decrease rare of blood pressure, the group in the systolic blood pressure decreased more than 20 mmHg in male triglycerides and the group in that diastolic blood pressure decreased within 6-11 mmHg showed more decrease rate of blood pressure than other groups. 5.Heart rate in exercise decreased after the execution of the program than before the execution of the program. 6.The increase of systolic blood pressure in exercise decreased in all the groups-the male group, female group, and total group, howere no change showing in their diastolic blood pressure. 7.The amount of oxygen uptake in exercise and after exercise incensed in all the groups- the male group, female group, and total group after the execution of the program than before the execution of the program. 8.Maximum oxygen uptake significantly increased(p<0.01) in all the groups-the male group, female group, and total group after the execution of the program. 9.A regression equation showing the relations between systolic blood pressure, heart rate and oxygen uptake was obtained, and it indcated a close relation between them. Based on the finding indicated so far, those results after the application of the treadmill exercise program to hypertensive adults such as decrease in blood pressure, weight, body fat rate, and body fat, increase of body fluids, improvement of the metabolism of serum lipids and cardiopulmonary function, and more increase of both systolic blood pressurea and diastolic blood pressure in the male group whose age is less than 50 years than in the male group whose age is more than 50 year-all these indicates significance. And also, based on the regression equation, the possibility to estimate heart rate and oxygen uptake with only systolic blood pressure is a noteworthy result of this study.

An alloy solidification problem is considered in a semi-infinite medium for a substance haying an extended temperature range between the solidus and liquidus temperatures. The analysis in the mushy gene has been performed by dividing the zone into two regions since the structures in the mushy gone are different depending upon the region where it is close to the solidus front or liquidus front. The solidus fraction in the mushy zone is assumed to be a linear function of temperature. The temperature distribution in each region is determined and the movements of the solidus and liquidus fronts are obtained as a function of time.

수면, 기억 그리고 학습의 연관성은 실제 매우 복잡하다. 많은 연구에도 불구하고 명확한 연구결과는 아직 없다. 우리는 이 연구에서 평소와는 달리 시험 전날 수면 변화 양상이 집중력에 어느 정도 영향력을 미치는지 알아보고자 하였고, 이를 이용해 효율적인 수면 관리를 할 수 있는 기초자료로 삼고자 하였다. 동국대 의대 본과 1학년생 중 지원자 30명과 본과 2학년생 10명을 대상으로 평상시 상태와 시험 직후 수면이 부족한 상태에서 각각 K-PES TEST를 실시하여 총 8항목에 걸쳐 암기력, 판단력, 단순반응의 변화정도를 검사하였다. 또 설문조사를 병행하여 결과에 영향을 미칠 수 있는 다른 인자들도 파악하였다. 수면량에 대한 부호 숫자 짝짓기(순간 판단력)을 검사한 결과, 인간의 최대 생리학적 기능은 꼭 수면부족에 의해 좌우되는 것은 아니다. 그러나, 수면감소는 피로를 증가시키고, 동기부여를 감소시키나 단, 새로운 사실을 학습하는 데에는 큰 영향을 끼치지 않는다. 즉, 수면부족으로 장시간 깨어있는 것은 정확성과 반응성을 떨어뜨린다. 흡연에 대한 부호 숫자 짝짓기(순간 판단력)을 검사한 결과, 니코틴의 수면에 대한 상호관계는 알려지지 않았고, 인간의 감정이나 의식, 인식에 영향을 주는 것으로 알고있지만, 장기적은 측면에서 흡연이나 알코올은 인식능력과 무관한 것 같다. 카페인에 대한 숫자 외우기(암기력)검사 결과, 카페인은 spacial selective attention에는 특별한 영향을 주지 않지만 지각과정이나 주의 집중에 큰 효과를 주며, 인간의 의식 수행에 긍정적인 효과를 준다. 즉 카페인은 활력, 혼란, 피로상태를 변화시키고 visual analog scales에서 휴식상태에 가까운 양상을 나타낸다. 또 48시간 동안 수면을 취하지 않은 사람에게 카페인은 집중력과 장시간의 좋은 기분을 유지하게 하였다. 그러나 규칙적, 비규칙적으로 먹는 사람간에는 인지수행력의 차이를 보이지 않으며 상용자에서는 상당한 내성이 보인다. 수면패턴에 대한 숫자 더하기(순간 판단력)검사 결과, 집중력은 수면패턴에 의해서도 영향을 받고, 수면패턴이 바뀌게 되면 순간판단력을 저하시킨다. This study was performed to evaluate relationship of sleep and attention, and to control sleep effectively. We conducted a K-PES test of 40 medical students. K-PES contains eight elements, for example, simple response, selective response, color pairing, OddEven discrimination, number addition, number-symbol matching, memory, right-tapping, left tapping. Through these, we tested changes of memory, judgement, simple response. And we conducted a questionnaire survey to exclude bias. Results are as follows. As a results of number-symbol matching test, we know that sleeplessness is not complete responsible for physiologic function for humans. But, decreased sleep increases fatigue and decreases motivation, but no influence on learning new materials. So, long term sleeplessness decreases precision and responsibility. As a results of number-symbol matching test on smoking, a relationship of nicotine and sleep is not certain. A point of view in long term period, smoking and drinking is not related cognition, even if we know that those influence mood, consciousness and cognition. As a results of memory work test on caffeine, caffeine does not influence spacial selective attention, but mainly does perception, attention and consiousness process. Namely caffeine changes energetic activities, chaos, fatigue states and shows resting state in visual analog scales In sleeplessness for 48 hours, caffeine produced attention and good mood for a long time. But, in case of cognitive process no significance shows in regular or irregular diet. Regular diet shows high resistance. As a results of number addition test on sleep patterns, seep patterns influence attention, changes of sleep patterns decrease a moment judgement.

Objectives : The aim of this study was to examine the behavioral and emotional problems associated with nocturnal enuresis in Korean children. Methods : Three hundred eighteen children with nocturnal enuresis, together with their parents, completed the Child Behavior Checklist (CBCL), Disruptive Behavior Disorder Scale according to DSM-IV (DBDS), Children's Depression Inventory (CDI), State-Trait Anxiety Inventory for Children (STAIC), and Piers-Harris Children's Self-Concept Scale (PHCSC). Ninety-three normal students were selected as the control group. Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in the nocturnal enuresis group according to the CBCL results. The nocturnal enuresis group also scored significantly higher in the ADHD and ODD profiles of the DBDS. The nocturnal enuresis group was more depressed and anxious than the control group according to the results of the CDI and STAI. The mean score of the PHCSC was significantly lower in the nocturnal enuresis group when compared to the normal control group. Conclusion : The results of this study suggest that children with nocturnal enuresis in Korea have clinically relevant behavioral and emotional problems. The findings support the link between nocturnal enuresis and psychopathology in Korean children.
