김종렬 ( Jong Ryoul Kim ),이은주 ( Eun Ju Lee ) 한국초등교육학회 2013 초등교육연구 Vol.26 No.4

본 연구의 목적은 초등학생의 정서지능과 정신건강의 관계에서 부모와 또래 지지의 매개효과를 알아보는 것이다. 대구의 초등학교 6학년 298명을 대상으로 정서지능, 부모와 또래 지지, 정신건강 검사를 통해 최종자료를 분석하였다. 연구 결과, 초등학생의 정서지능, 부모와 또래 지지 및 정신건강의 구조적 관계를 설정한 최종모형은 적합한 것으로 나타났다. 둘째, 정서지능은 부모와 또래 지지에 직접적인 영향을 미치고 있었으며, 부모와 또래 지지는 초등학생의 정신건강에 직접적인 영향을 미쳤다. 셋째, 정서지능은 부모와 또래 지지를 매개하여 정신건강에 통계적으로 유의미한 영향을 미쳤다. 본 연구 결과를 통해, 개인적 요인인 정서지능과 환경적 요인인 부모와 또래 지지는 초등학생의 정신건강에 유의미한 영향을 미치는 변인임을 알 수 있었다. 마지막으로 본 연구의 제한점을 바탕으로 후속연구를 위한 논의를 하였다. The purpose of this study was to examine the mediation effects of parents` support and peer`s support in the relationship between emotional intelligence and mental health of elementary school students. 298 students were sampled from 3 elementary schools in Daegu. The results were as follows: First, result from structural equation modeling was found to support the final model which included emotional intelligence, parents` support and peer`s support, and mental health. Second, emotional intelligence had positive direct effects on parents` support and peer`s support. Also, parents` support and peer`s support had positive direct effects on mental health. Third, parents` support and peer`s support had significant mediating effects on the relationship between emotional intelligence and mental health. Based on these results, it should be recognized that emotional intelligence and parents` support and peer`s support are significant determinants of the elementary student`s mental health. Finally, suggestions for future research were discussed based on limitations of this study.

Long-term treatment with glucocorticoid leads to the development of osteoporosis and osteonecrosis. In contrast to the marked inhibitory effect of pharmacological doses of glucocorticoids on bone formation, the relationship between physiological concentrations of glucocorticoids and osteoprogenitor cell proliferation and phenotypes has not been elucidated yet. In addition, the effects of dexamethasone treatment on the proliferation and osteoblastic differentiation of osteoprogenitor cells are also controversial. The purpose of this study was to examine the effects of dexamethasone on the proliferation and osteoblastic differentiation of periosteal-derived cells. Periosteal-derived cells were obtained from mandibular periosteums and introduced into the cell culture. After passage 3, the cells were further cultured for 21 days in the osteogenic induction medium with different dexamethasone concentrations of 0, 10, and 100 nM. The proliferation and osteoblastic phenotypes of periosteal-derived cells were promoted in dexamethasone-treated cells than in untreated cells. Among the dexamethasone-treated cells, cell proliferation was slightly greater in 10 nM dexamethasone-treated cells than in 100 nM dexamethasone-treated cells. Histochemical staining and the bioactivity of alkaline phosphatase (ALP) were higher in 100 nM dexamethasone-treated cells than in 10 nM dexamethasone-treated cells. Similarly, von Kossa-positive mineralization nodules and calcium content were also more evident in 100 nM dexamethasone-treated cells than in 10 nM dexamethasone-treated cells. These results suggest that dexamethasone enhances the in vitro osteoblastic differentiation of periosteal-derived cells. The present study also demonstrates that higher dexamethasone concentrations reduce the in vitro proliferation of periosteal-derived cells.

The columella, nasal tip, lip relationship in the secondary bilateral cleft deformity remains an enigma and a great challenge for the cleft surgeon. A subset of patients with bilateral cleft lip still require columellar lengthening and nasal correction, despite the advances in preoperative orthopedics and primary nasal corrections. An approach to correct this deformity is described. This consists of 1) lengthening the columella, 2) open rhinoplasty, allowing definitive repositioning of lower lateral cartilages, ear cartilage grafting to the tip and columella when necessary, 3) nasal mucosal advancement, 4) alar base narrowing and 5) reconstruction of the orbicularis oris as required. In surgical repair of the cleft lip nose, the timing of the operation(during lip closure, before or after the puberty growth sput), and the operative technique play a key role in the final result. In this study, 13 cleft lip patients who had undergone a secondary cheilorhinoplasty at the Department of Oral and Maxillofacial Surgery, Pusan National University Hospital were evaluated to check the proper time and method of the operation.

Purpose : The purpose of this study was to examine the expression of various angiogenic factors during osteoblastic differentiation of periostealderived cells and the effects of osteogenic inductive medium of periosteal-derived cells on the proliferation of endothelial progenitor cells. Materials and methods : Periosteal-derived cells were obtained from mandibular periosteums and introduced into the cell culture. After passage 3, the cells were divided into two groups and cultured for 21 days. In one group, the cells were cultured in the DMEM supplemented with osteogenic inductive agent, including 50g/ml L-ascorbic acid 2-phosphate, 10 nM dexamethasone and 10 mM -glycerophosphate. In the other group, they were cultured in DMEM supplemented without osteogenic inductive agent. VEGF isoforms, VEGFR-1, VEGFR-2, and neuropilin-1 mRNA expression was observed. Human umbilical cord blood-derived endothelial progenitor cell proliferation was also observed. Results : The expression of VEGF isoforms was higher in osteogenic inductive medium than in non-osteogenic inductive medium. The expression of VEGFR-2 was also higher in osteogenic inductive medium than in non-osteogenic inductive medium. However, the expression of VEGFR-1 and neuropilin-1 was similar in both osteogenic inductive medium and non-osteogenic inductive medium. In addition, conditioned medium from differentiated periosteal-derived cells stimulated human umbilical cord blood-derived endothelial progenitor cell numbers compared to conditioned medium from non-differentiated periosteal-derived cells. Conclusion : These results suggest that in vitro osteoblastic differentiation of periosteal-derived cells has angiogenic capacity to support endothelial progenitor cell numbers.

A 14-year-old male patient was referred to us for evaluation of Right TMJ clicking sound and mandibular deviation during mouth opening. On examinaaation, protrusion and lateral excursion was also restricted. Radiographs showed hook-like curved elongation of Right coronoid process with limitation o right condylar translation. His past medical and dental history was noncontributory. This patient underwent an extraoral coronoidectomy and the specimen revealed coronoid process malformation mimicking condylar head. Microcoically, the specimen discloses mature bony trabeculae. At postoperative 5 days, physical therapy was instituted. At present, this patient could open his mouth well with any clicking sound and mandibular deviation. The asymmetric face of this patient is expectated to be corrected by periodic observation and remained growth porential. If not to be corrected, orthognathic surgery will be done. 이상에서 저자들은 하악관절과두와 유사한 형태를 보이는 편측성과 양측성 오훼돌기 변형증의 가각의 원인, 성장형태, 발현연령과 성별 및 발생기전등에 대해서 문헌 고찰을 해보 았다. 본 증례에서도 정확한 원인은 알 수 없지만 환자의 과거 병력상 우축 악관절의 외상으로 추정된다. 외고작으로 exploration시 coronoidotemporal area에서 또 다른 관절의 양상을 보여 주어 이중관절을 이루고 있었으며 오훼돌기의 절제와 함께 물리치료 후 환자는 개구시 악골의 심한 우측 악관절의 관절잡음도 들리지 않았다. 현재 환자에게서 볼 수 있는 안면비대칭은 향후 주기적인 관찰과 성장 여력에 의해 개선이 기대되지만 추후 악교정 수술이 필요할 수도 있을 것으로 사료된다.

For the purpose of studying postsurgical stability of mandibular prognathism, 18 patients(8 men and 10 women) were selected who underwent sagittal split ramus osteotomy and lateral cephalograms taken preoperatively, immediate postoperatively, and over 6-month follow-up were traced and analysed. The following results were obtained. 1. Average magnitude of setback vas 11.0mm, and aberage relapse was 3.0mm, so the rate of relapse was 27%. 2. Magnitude of mandibular setback contributed to relapse. 3. The patients of less than 10mm setback showed average 10% of relapse rate, and it was of little clinical significance. 4. Proper detachment of pterygomasseteric sling prevention of clockwise rotation of proximal segment and rigid fixation are recommended for the better postoperative stability.

Halothane hepatitis is a rare complication after halothane anesthesia. Its existence, incidence, etiology remained controversial. We experienced one case of malunited fracture which was treated by iliac bone graft complicated with halothane hepatitis. Nine days after anesthesia, the patient became febrile and his whole body was covered with rashes. The serum bilirubin and transaminase levels were high. He was treated with corticosteroids under the diagnosis of halothane hepatitis and the hepatic function had improved.

Alveolar bone grafting is an essential component of successful surgical rehabilitation in many common cleft deformities. Primary alveolar bone grafting is defined as alveolar bone grafting which takes place before eruption of the primary dentition or before 1 year of age. The major objective in primary alveolar bone grafting is to prevent significant maxillary segmental collapse and arch disturbances. If severe, this can make secondary rehabilitation difficult, costly, and protracted. Such early stabilization may eliminate or, at least, decrease the amount of orthodontic arch expansion required during the transitional dentition period. Furthermore, early obliteration of alveolus fistulae improves speech and dental hygiene. It is critical that abutting maxillary segmental alignment be achieved(generally when the patient is 8 to 10 months of age) before grafting. Otherwise, the amount of dissection necessary to develop mucosal flaps for bone graft coverage will be more extensive, thus risking increased scar formation with potential adverse effects on growth We report a preliminary result of 4 cases of primary alveolar bone graft using rib bone, performed by limited dissection and onlay graft technique at 8 to 10 months of age. They showed satisfactory clinical results especially in terms of growth up to now.

Gunshot injuries can range from the most minor to the life-threatening. Multidisciplinary care is required for successful management of patients, In the acute phase, care may involve emergency surgeons, anaesthesists, neurosurgeons, ophthalmic surgeons, vascular surgeons, ENT specialist in addition to the oral and maxillofacial surgeons. Afterwards, definitive treatment of facial gunshot injuries depends ultimately on the abilities and skills of the oral and maxillofacial surgeons, and their appreciation of such injuries. The timing and sequence of the surgical procedures used for reconstruction and rehabilitation of maxillofacial gunshot injuries are crucial to a successful outcome and aesthetic result. If incorrect, they may lead indefinitely to infection, graft rejection, wound dehiscence with consequent multiple revisional operations and complication which will prolong hospital stay and increase treatment costs and morbidity on those patients. We present a gunshot case of a 46-year-old man who tried to commit sucide, and have avulsive and penerating wounds on the face and the neck. We removed the scattered bullets and fragments successfully and the wounds were closed primarily.
