Continuous positive airway pressure (CPAP) has been known as a safe and effective therapy for the patients with obstructive sleep apnea (OSA). Previous studies on CPAP treatment have often reported significant improvement in mood state in those patients. However, there are very few reports on its potential to induce manic or hypomanic episode in the patients with OSA. We report a case of 34-year-old patient with OSA who developed manic and hypomanic episodes consecutively after CPAP treatment with facial mask. We suggest that CPAP treatment could induce a manic or hypomanic episode in patients with obstructive sleep apnea.

뼈의 역학기능을 예측하는 인자(predictive factor) 로서 골밀도(BMD)만으로는 충분하지 않다는 최근의 임상결과는, 골밀도 이외의 새로운 뼈의 강도 및 골절리스크를 지배하는 인자의 중요성을 보여준다. 이와 같은 골역학기능에 대한 골밀도 이외의 부가적인 지배인자를 골질(bone quality)이라고 하는데, 다양한 골질관련인자(bone quality-related factor) 중 하나의 지표로서 뼈의 주성분인 생체아파타이트(BAp)의 결정학적 방향성에 주목, 대표적인 경조직 질환을 해석하였다. 파골세포결손에 의해 대리석증을 유발하는 op/op마우스는 골밀도의 변화뿐만 아니라, 골질의 유의한 변화가 있었다. 즉, 이와 같은 결과는 파골세포결손에 의한 조골세포의 활성저하의 의해 골질이 저하됨을 시사하는 결과이며, 파골세포 과잉의 의해 골다공증을 유발하는 OPG-KO마우스는 골밀도가 급격히 저하됨과 동시에, BAp배향성도 급격히 낮아졌다. 즉, 골대사회전의 상승에 따른 섬유성골(woven bone)의 형성에 의해 BAp의 결정성장이 억제되며, 그 결과 BAp배향성이 저하된다고 사료된다. 이상, 본 연구에서는 대표적인 골 질환조직을 각각의 정상골과 비교함으로써, 골양(BMD)의 변화뿐만 아니라 골질(BAp배향성)의 변화를 발견하였다. 이와 같은 변화는 골질지표로서 BAp배향성이 유효하다는 것을 강하게 시사한다. 따라서 본 연구에 의해 얻어진 견해는 경조직 질환의 병리해명에 적용 가능함과 동시에, 경조직 질환의 진단 응용이나 치료약 개발, 임플란트 개발 등 폭넓은 분야에 유용하다고 할 수 있다.

Improvements in jaw relationship through clockwise rotation of the mandible may be desirable in some Class III patients with short low facial height. The aim of this study was to examine the treatment effect of face mask for Class III malocclusion patients according to their low facial morphology. Methods: Class III patients in their pubertal growth period were divided into two groups (Group 1, high LFH; Group 2, low LFH) according to lower facial height (LFH) by Ricketts (norm, 47). treatment changes between groups after face mask treatment was compared not only for hard tissue but also for soft tissue. Results: There were no significant differences between the two groups for the skeletal and soft tissues of the maxilla. There were no significant differences between the two groups for the skeletal posterior movement of the mandible, but posterior movement of the mandibular soft tissues in group 2 was larger than group 1. There were no significant differences between the two groups for the vertical hard tissue proportion changes of the mandible, but the vertical soft tissue proportion changes of the mandible in group 2 was larger than group 1. There was a significant correlation between the sagittal hard tissue and soft tissue changes of the maxilla and mandible, but there was no significant difference in the vertical changes. Conclusion: The clockwise rotation of the mandible occurred from use of the face mask, and posterior movement of soft tissues of the mandible was higher in Cl III patients with low LFH than with high LFH.

The treatment plan for orthognathic surgery must be based on accurate predictions, and this can be produced the most esthetic results. Treatment of prognathic mandible in adult is usually orthognathic surgery using mandible set back, but mandible with retruded chin point is needed additional chin augmentation. In this case, the directions between mandible and chin point are different therefore, the prediction of soft tissue reactions must be modified. In this study, we materialize the patients who was taken orthognathic surgery due to prognathic mandible, 11each(Group A) was taken only Bilateral Sagittal Sprit Ramus Osteotomy (BSSRO), 9each(Group B) was taken additional advancement genioplasty. The lateral cephalometric radiography taken 8 months later after orthognathic surgery by this patients were used. The results of this study were as follows : 1. The profile of lips was favorable after surgery due to upper lip to I-line became prominent and lower lip tc E-line was retruded. 2. In both group, upper lip moved posteriorly and nasolabial angle was increased. 3. The ratio of the soft tissue profile change in POGs point to skeletal B point movement was $84\%$ in group A and $66\%$ in group B, and there was statistical significance between group A and group B. 4. Vertical movement of hard tissue points is decreased in group A.

The purposes of this study were to investigate the actual conditions and deal with the psychological characteristics of adolescent cellular phone addicts through the Minnesota Multiphase Personality Inventory (MMPI). The subjects of this study were 407 senior high school students (male 185, female 222) in 2nd grade in Daegu. The cellular phone addiction inventory (CPAI) was designed on the basis of an interview process, referring to the Young's Internet Addiction Self Diagnosis Scale. SPSS version 10.0 was employed for data analysis. The mean score of the adolescent addict group was significantly higher than the non-addict group in Scale Pd, Pa, Pt, Sc and Ma. This result indicates that the cellular phone addict group is likely to suffer from more serious pathological disorders than the non-addict group. The rate of addictive adolescents was significantly higher in the addict group than in the non-addict group in psychological problematic score ranges in Scale Sc (Schizophrenia) and Ma (Hypomania). The study result suggests that adolescents who addictively use a cellular phone will be more likely to show immaturity, instability, impulsive personality, excessive activities, and escapism.

The purpose of this study was to examine emotional characteristics and to provide information about the special needs of counselling of science gifted in Korea. The subjects were 143 science gifted high school students in Busan that had been tested MBTI and MMPI-A. The distribution map of MBTI type was examined and Pearson's correlation, one-way ANOVA, multiple regression analysis were used to analyse the relation between MBTI and MMPI-A through SPSS 17.0 program. The results showed as follows: first, ENTP, INTP, ISTJ personality types and NT temperament type were the most frequently from the distribution map of MBTI type. Second, F1, F2, F, Hs, D, Pt, Sc and Si scales of MMPI-A were positively related to I preference of MBTI and K and Ma scales of MMPI-A were significantly related to E preference of MBTI from Pearson's correlation. Third, The score of IN group was significantly more high in F1, Hs, D, SC and Si scales of MMPI-A than other group in the relation between two combination preferences of MBTI and scale of MMPI-A. The following results were same; IS group in D, Si scales, EN group in Ma scale, IT group in Hs, D, Pt and S scales, IF group in VRIN, D and Si scales, ET in Ma scale, IJ group in D and Si, IP group in F1, F, Hs, D, Hy, Pt, Sc and Si scales, EJ and EP groups in Ma scale. Finally, I preference of MBTI by F1, F2, F, Hs, D, Pt, Sc and Si scales of MMPI-A, E preference of MBTI by Ma scale of MMPI-A, F preference of MBTI by K scale of MMPI-A and P preference of MBTI by Hy scale of MMPI-A were significantly predicted from multiple regression analysis. Limitations of the current study and the suggestions for further research were offered.

In recent decades, dental erosion has received a considerable amount of attention with a steady increase of the prevalence. However, the awareness of this matter in our society, including dentistry is still lacking. Dental erosion is an irreversible loss of dental hard tissue leading to a complex condition. To prevent detrimental effects, it is important to detect conditions as early as possible and inhibit progression. In children and adolescents, early intervention is more important than in adults. As dental erosion is a multifactorial condition, dentists need to fully understand the phenomena and do systematic oral examination with thorough history taking for early diagnosis. When the main etiological factor is detected, it is necessary to make an effort to eliminate it and stop progression of the lesions with preventive measures. Restorative treatment should not be started unless substance loss reaches a certain level. Once the decision is made for treatment, care must be taken to choose the least invasive method.

Dental erosion is a complex disease of multifactorial etiology with high risk of loss of tooth structure, which still has not been appropriate interest. The aim of this study was to assess the prevalence and risk indicators of dental erosion in Korean school children. A cross-sectional survey was performed on 664 children aged 8~9 years. Data concerning gender, types of caregiver, dietary habits, oral hygiene habits and parental knowledge were obtained from a questionnaire, which was answered by the parents of the children. Association between erosion and the factors were statistically analyzed with chi-squared test and independent t-test at a significance level of 0.05. Dental erosion was present in 242 children. In carbonated drinks, dental erosion was significantly associated with preference, frequency of consumption and the ingestion method (p < 0.05). In fruit juices, dental erosion was significantly associated with preference and frequency of consumption (p < 0.05), but no significant associations were found with the ingestion method (p > 0.05). There were no significant associations between dental erosion and gender, type of caregiver, oral hygiene habits and parental knowledge (p > 0.05). In conclusion, it was considered that motivation to be followed by practice is important as well as education for prevention of dental erosion.
