Characteristics of Superior Children as a Screening Test of Gifted students The purpose of this study was to investigate the usefulness of Korean version of checklist for behavioral characteristics of superior children as a screening test for gifted students. Total 397 children were tested KEDI-WISC (Korean version of Wechsler Intelligence Scale for Children), and their parents or primary caretakers took the checklists for behavioral characteristics of superior children individually. Total subjects were divided into 3 groups based on their Full IQ score of KEDI-WICS. The children of IQ 130 and over was gifted group, and those of IQ 115-130 was superior group, and those of below IQ 115 was average group. The analyses of behavioral checklist scores among the groups, gender, grades differences and item analysis of behavioral checklist were done for the purpose of discrimination among 3 groups. As a result, it was found that the Korean version of checklist for behavioral characteristics of superior children was very useful as a screening test for gifted correlations between checklist scores and verbal, performance and full IQ scores were significantly high, which means that IQ and checklist scores were very related. Twenty out of 50 items were found to be discrimination items between gifted and superior group. However, there was no significant difference between grades and gender on the checklist score.

Superior Vena Cava Syndrome: Dacron and Nylon graft between the left innominate vein and the right atrial appendage. Two cases with typical superior vena cave syndrome treated by by-pass graft between the left innominate vein and the right atrial apepndage were presented. One of them was a 58 year old farmer who suffered from marked swelling of the neck and upper half of body, the other was a 50 years old government employee who had acutely progressive symptoms of superior vena cave obstruction. Both of cases revealed that [1] cubitel venous pressure was markedly increased. [2] tumors were noted in the posterior mediastinum by laminography. [3] preoperative cavogram showed the occlusion of superior vena cava and marked collaterals. Dacron and Nylon graft were inserted between the left innominate vein and the right atrial appendage. Postoperatively, the symptoms were relieved markedly, showing edema free face and decreased cubital venous pressure. Postoperative cavogram showed patent graft. Histologically the first case was diagnosed as squamous cell carcinoma and the second as undifferentiated carcinoma, originated probably from bronchus. Total doses of 3150 r X-ray irradiation and 5000 mg of 5-FU were administered in each cases. The first case expired 11 months postoperatively without recurrence of superior vena cave obstruction symptom and the second case is living now without obstruction signs, 4 months after by-pass operation.

Introduction: To evaluate the efficacy of superior gluteal artery-pedicled iliac crest for the treatment of avascular necrosis of femoral head. Material & Method: From January 2001 to October 2001, we used the superior deep branches of superior gluteal artery for the pedicled posterior iliac crest bone graft to revascularize the avascular femoral head in 4 patients. They were 1 man and 3 women, and the mean age of the patients was 34 years (range, 27 to 60). The average follow-up after surgery was over 57 months (range, 15 to 82). We analyzed the clinical results by the Harris hip score, and evaluated the vascularity of the femoral head by radiographic methods. Results: All cases showed no evidence of collapse on femoral heads and good revascularizations on the radiographic images. The average Harris hip score was 88.5 points. There was no complication. Conclusion: The revascularization procedure using the superior gluteal artery-pedicled posterior iliac crest was thought to be one of the effective and promising techniques for the treatment of the avascular necrosis of femoral head.

Purpose : To describe the MRI findings of the antero-superior attachment of the disc in patients with internal derangement. Materials and Methods : One hundred fifty-six MR images from 40 normal subjects and 55 abnormal subjects were classified into three study groups of normal, anterior disc displacement with reduction and anterior disc displacement without reduction. On both closed- and open-mouth proton density sagittal images, the depiction of the antero-superior attachment of the disc and its demarcation from the disc were evaluated in three cuts of lateral, central and medial one thirds of the condyle. Results : The depiction of antero-superior attachment was more frequent by the order of normal, anterior disc displacement with reduction and anterior disc displacement without reduction groups, and the significant differences were found on lateral cut of the closed images and lateral and central cuts of the open images. In study for the demarcation between the antero-superior attachment and the disc the lateral cut of the closed images and all three cuts of the open images showed significant differences. Conclusion : Open images are useful to show the difference in depiction of the antero-superior attachment of the disc among the TMJ groups.

This study was performed for the purpose of investigating the relation between width of temporomandibular joint space and craniofacial morphology in patients with CMDs. The subjects utilized here were aged from 16 to 63 years old and 19 male and 46 female. For the study, each patient was taken radiographs by Transcranial and Lateral Cephalographic projection and the films were traced with routine method. The measured items were anterior, superior, posterior joint space and relative condylar position to the deepest part of glenoid fossa in Transcranial film and items related vertical and/or horizontal growth in Cephalogram. The data were processed with SPSS/PC+ package for statistical analysis. The obtained results were as follows : 1. Anterior joint space in affected side were wider than that of unaffected side, but for superior and posterior joint space, the value of unaffected side were more than those of affected side. 2. Superior or posterior joint space of affected side were significantly correlated with items related vertical growth, such as ramus height, Jarabak ratio, FMA. From this, the following cold be proposed, the wider the joint space of superior or posterior aspect of affected side was, the more the patient showed growth pattern of counter clockwise. 3. Superior or posterior joint space of affected side were significantly correlated with items related horizontal growth, such as SNPo, NAPo, APDI and ANB. From this the following could be proposed, the wider the joint space of superior or posterior aspect of affected side was, the more the patient showed anterior displacement of mandible. 4. It would be proposed that the diagnositic value of superior and posterior joint space of affected side in transcranial radiograph was excellent.

Objectives: This study sought to investigate the positioning of the posterior superior alveolar artery in relation to the performance of the maxillary sinus bone graft procedure in a Korean population. Materials and Methods: We identified the position of the posterior superior alveolar artery relative to 93 maxillary sinuses in 58 patients and determined the distance from the inferior border of the artery in the premolar and molar areas to the alveolar ridge and sinus floor. Results: The mean distance from the alveolar ridge to the posterior superior alveolar artery in the dentate group ($20.62{\pm}3.05mm$ in the premolar region, $17.50{\pm}2.84mm$ in the molar region) was greater than as compared to the edentulous group ($18.83{\pm}2.79mm$ in the premolar region, $15.50{\pm}1.64mm$ in the molar region), and this difference was statistically significant (P<0.05). In contrast, there was no statistically significant difference (P>0.05) between the mean distance from the sinus floor to the posterior superior alveolar artery in the dentate group ($8.21{\pm}2.79mm$ in the premolar region, $7.52{\pm}2.07mm$ in the molar region) or in the edentulous group ($7.75{\pm}3.31mm$ in the premolar region, $7.97{\pm}2.31mm$ in the molar region). Conclusion: Prior to surgery, it is important to evaluate the position of the posterior superior maxillary artery by using computed tomography scans. The premolar area is safer than the molar area for performing the maxillary sinus bone graft without bleeding.

This study is to study the overall structural relationship between work-life balance(WLB), superior trust, workplace happiness, and organizational commitment. The goal of this study is to study how WLB and superior trust affect workplace happiness, how workplace happiness affects organizational commitment, and the mediating effect of workplace happiness. Survey data were collected from incumbents working in large companies and SMEs, validity and reliability of research items were reviewed, and research hypotheses were tested using path analysis. As a result of testing the research hypothesis, WLB and superior trust have a positive (+) effect on workplace happiness, and workplace happiness has a positive (+) effect on organizational commitment. Also, job satisfaction plays a role as a partial parameter between WLB, superior trust, and organizational commitment. Based on the hypothesis test results, it was confirmed that the higher the level of WLB and superior trust, the higher the level of work satisfaction. Based on the research results, a plan was suggested for Korean corporate members to achieve workplace happiness and organizational commitment.

The development of the superior cervical ganglion was studied by electron microscopic method in human fetuses ranging from 40 mm to 260 mm of crown-rump length (10 to 30 weeks of gestational age). At 40 mm fetus, the superior cervical ganglion was composed of clusters of undifferentiated cell, primitive neuroblast, primitive supporting cell, and unmyelinated fibers. At 70mm fetus, the neuroblasts and their processes were ensheated by the bodies or processes of satellite cells. The cytoplasm of the neuroblast contained rough endoplasmic reticulum, mitochondria, Golgi complex, Nissl bodies and dense-cored vesicles. As the neuroblasts grew and differentiated dense-cored vesicles moved away from perikaryal cytoplasm into developing processes. Synaptic contacts between the cholinergic axon and dendrites of postganglionic neuron and a few axosomatic synapses were first observed at 70 mm fetus. At 90 mm fetus the superior cervical ganglion consisted of neuroblasts, satellite cells, granule-containing cells, and unmyelinated nerve fibers. The ganglion cells increased somewhat in numbers and size by 150 mm fetus. Further differentiation resulted in the formation of young ganglion cells, whose cytoplasm was densely filled with cell organelles. During next prenatal stage up to 260 mm fetus, the cytoplasm of the ganglion cells contained except for large pigment granules, all intracytoplasmic structures which were also found in mature superior cervical ganglion. A great number of synaptic contact zones between the cholinergic preganglionic axon and the dendrites of the postganglionic neuron were observed and a few axosomatic synapses were also observed. Two morphological types of the granule-containing cells in the superior cervical ganglion were first identified at 90 mm fetus. Type I granule-containing cell occurred in solitary, whereas type II tended to appeared in clusters near the blood capillaries. Synaptic contacts were first found on the solitary granule-containing cell at 150 mm fetus. Synaptic contacts between the soma of type I granule-containing cells and preganglionic axon termials were observed. In addition, synaptic junctions between the processes of the granule- containing cells and dendrites of postganglionic neuron were also observed from 150 mm fetus onward. In conclusion, superior cervical ganglion cells and granule-containing cells arise from a common undifferentiated cell precursor of neural crest . The granule-containg cells exhibit a local modulatory feedback system in the superior cervical ganglion and nay serve as interneurons between the preganglionic and postganglionic cells.

A unhealthy 58-year-old male patient required extraction of left upper second molar due to advanced periodontitis. Lidocaine contained 1 : 100000 epinephrine for left posterior superior alveolar nerve block was administered in the mucobuccal fold above the second molar to be treated at the local private dental clinic. After four hours of posterior superior alveolar block anesthesia, patient feeled double vision and discomfort of eyeball movement. At next day, he complained difficulty of left eyeball movement, vertigo and diplopia. He was referred to our department via local clinic and department of ophthalomology of our hospital. He was treated by medication and eyeball exercise, and then follow up check. The double vision and medial rectus muscle palsy disappeared patially after 2 months of block anesthesia. We described herein an ocular complication of diplopia and inferior rectus muscle palsy after posterior superior alveolar nerve block for extraction of left upper second molar, and review the cause or origin of this case. The autonomic nervous system is presented as the logical basis for the untoward systems of ophthalmologic sign likely to diplopia and inferior rectus muscle palsy, rather then simple circulation of anesthetic solution in the vascular network.
