Background: Although the results of the surgical management for complete atrioventricular septal defect (c-AVSD) have improved, the optimal surgical strategy is still controversial. The aims of this study are to evaluate the outcome of c-AVSD repair and to define the risk factors related to reoperation. Material and Method: We retrospectively reviewed the medical records of 35 patients (8 males and 27 females) who underwent the total correction of c-AVSD from August 1996 to March 2008. The median age at repair was 5.2 months (range: 3 days$\sim$82 months). Sixteen patients (45.7%) were associated with Down syndrome. Prior palliative operations were performed in 4 patients. The one-patch techniques were performed in 3 patients, and the two-patch techniques were done in 32 patients. Result: There was 1 early death (2.9%). The median follow-up period was 68 months (range: $2\sim134$ months) for 34 survivors. There was no late death. Reoperations were performed in 5 patients (14.3%) for severe left atrioventricular valvular regurgitation (AVVR). Nine patients (25.7%) showed left an AVVR of more than grade III. Associated major cardiac anomalies and the use of Gore-Tex patch for ventricular septal closure were the risk factors for postoperative left atrioventricular valve failure and reoperation. Conclusion: In this study, we found that surgical repair of c-AVSD was safe and effective. However, the high reoperation rate after repair remains a problem to be solved.
Purpose: The aims of this study were to investigate the stereoacuity and subjective symptoms of aniseikonia with prescription of the size lens. Methods: Participants were myopic anisometropia patients with the binocular refraction difference between 1.75 D~3.50 D. Inclusion criteria of participants were no ocular pathology, no amblyopia, more than 1.0 of corrected visual acuity. With fully corrected spectacles and a correction with the size lens, Awaya aniseikonia test and Randot Stereo test were conducted respectively. In addition, subjective symptoms were also examined using questionnaire. Results: As the anisometropia increased, the aniseikonia increased. Under the anisometropia with same refractive correction was different for each individual. The prescription of size lens caused less aniseikonia than the general prescription of glasses. In addition, prescription of the size lens improved stereoacuity and relieved the symptoms of asthenopia. Conclusions: The prescription of size lens that can correct aniseikonia with prescription of glasses can improve stereoacuity and reduced asthenopia.

Impacted molars are not usual with the prevalence rate of less than 1%, however problems such as infraocclusion, extrusion of the opposite tooth and lack of space are caused. If molars are impacted, radiographic check-up and observations are needed as they play an important role in skeletal development and mastication. Causes of impaction are underdevelopment of roots, supernumerary teeth, cysts, odontomas, ankylosis and etc. In our first case, we present impacted molar which was surgically exposed and orthodontically traded. As the developmental state of the root was less than half at first visit, we observed until the root was 2/3 in its length and traction was carried out. The second case is orthodontic traded molar with compleate enucleation of the existing cysts. When trading impacted molars, direct bonding of attachments to the tooth and light continuous forces are recommended so as to ankylosis, external absorption and periodontal attachment loss avoid. Fixed appliances tract the teeth on arch and obtain eruption spaces without patient's cooperation. We report surgically exposed and orthodontically traded molars which resulted in good occlusion and patients satisfaction.
Purpose: This study was performed to investigate the effect of induced ametropia on static posture for body balance. Methods: Twenty subjects (10 males, 10 females) of average age $23.4{pm}2.70$ years were participated and ametropia(binocular myopia; BM, simple myopic anisometropia; SMA, binocular hyperopia; BH, and simple hyperopic anisometropia; SHA) were induced with ${pm}0.50D$, ${\pm}1.00D$, ${\pm}1.50D$, ${\pm}2.00D$, ${\pm}3.00D$, ${\pm}4.00D$, ${\pm}5.00D$, respectively. General stability (ST), weight distribution index (WDI), and fall risk index (FI) were measured using TETRAX the biofeedback systems. Each index of the body balance was evaluated for 32 seconds in each ametropic condition and those value was compared with the value in fully corrected condition. Results: The ST showed significant increase from +0.50 D under condition of BM, from +1.00 D under condition of SMA, from -1.00 D under condition of BH, and from -1.50 D under condition of SHA compared with under condition of fully corrected condition, respectively. The FI showed significant increases from +4.00 D under condition of BM, from -1.00 D under condition of BH, and from -1.50 D under condition of SHA. The WDI show no change in all ametropia condition. Conclusions: Whatever ametropia is, uncorrected refractive error could reduce the general stability of body balance and increase the falling risk.
Although the delayed type of rhinoplasty is currently acceptable in the correction of cleft lip and nasal deformity, Delaire tried to achieve the simultaneous nasolabial reconstruction and muscular rearrangement that affect the subsequent skeletal growth of the face. the anatomic muscular reconstruction can be achieved by making the anchorage of the nasolabial muscles of the cleft side to the nasal septum and muscles on the non-cleft side. Two cleft lip patients of 6 and 7 year-old without any previous operation history were treated with the functional cheilorhinoplasty. One patient with incomplete cleft lip underwent a cheiloplasty along with the rearrangement of orbicularis oris muscle. The other patient had a complete cleft lip and palate with accompanying nasal deformity, who underwent the functional cheilorhinoplasty with the reconstruction of anterior nasal base. All the operation was done under the general anesthesia and patients healed without any significant complications. In the incomplete case, the shapes of Cupid's bow was restored, and the length of columella was regained comparable to the non-affected side. In the complete cleft lip and palate case, the depressed nostril was reconstructed with acceptable symmetry by complete releasing of deformed alar cartilage undermined with a dissecting scissors. In summary, the functional repair of cleft lip and nose could be possible at the same time by using Delaire method. This method is effective to correct the primary nasolabial deformity, which results in the restoring favorable anatomy and its function.

Purpose : The purpose of this study was to investigate the clinical features and outcome in newborns undergoing cardiac surgery. Methods : Eighty two neonates underwent heart surgery for congenital heart defect at Kyungpook National University Hospital between March 2000 and February 2006. Patient characteristics (sex, age, diagnosis), pre-operative conditions, operation type, postoperative complications and mortality were reviewed retrospectively. Results : In 82 patients, 41 (50%) were male. The mean age and weight at operation were 12 days and 3.2 kg, respectively. The common cardiac anomalies were complete transposition of the great arteries (TGA), Tetralogy of Fallot (TOF), pulmonary atresia with intact ventricular septum, and single ventricle variants. Fifty seven operations were performed with cardiopulmonary bypass and corrective surgery was done on 54 patients. Arterial switch operation and modified Blalock-Taussig shunt were most frequently performed as corrective and palliative operations, respectively. The early hospital mortality rate was 7%; the late mortality was 3.9%. Complications were acute renal insufficiency, delayed sternal closure, wound infection, arrhythmia, and brain hemorrhage. Conclusion : During the last 6 years, the outcomes of cardiac surgery for congenital heart defects in neonates improved by progress in perioperative, anaesthetic, surgical, and postoperative care.

The purpose of this study was to examine the relationships between job stress, life satisfaction, burnout, and self-compassion. A survey was conducted in February 2018 for employees working at the Korea Legal Protection and Welfare Agency, and 213 data were included in the final analysis. A structural model was developed to examine the relationships between the variables used in this study, and the model-fit and mediating effects of the developed model were examined using SPSS and AMOS. For this study, the Korean occupational stress scale, life satisfaction scale, Maslach burnout inventory, and Korean self-compassion scale were used. We found that self-compassion is fully mediated between job stress and life satisfaction and between job stress and burnout. Also, life satisfaction is partially mediated between self-compassion and burnout. These results mean that self-compassion has significant effects on job stress, life satisfaction, and burnout. In particular, the mediating effect of self-compassion shows the vicious cycle of high job stress - low self-compassion - low life satisfaction - high burnout. Based on these results, the future implications of program development based on self-compassion strategies were discussed in order for workers in correctional facilities to decrease job stress and burnout and increase life satisfaction.
Purpose : To analyze the eyeglasses supply system for ametropic soldiers in ROK military. Methods : We investigated and analyzed the supply system of eyeglasses for the ametropic soldiers provided by the Korean military. The refractive powers and corrected visual acuity were measured for 37 ametropic soldiers who wear insert glasses for ballistic protective and gas-masks supplied by the military based on their habitual prescriptions. Full correction of refractive error was prescribed for subjects having less than 1.0 of distance visual acuity, and comparison was held for inspecting the changes in corrected visual acuity. Suggestions were provided for solving the issues regarding current supplying system, and this study investigated the applicabilities for utilizing professional optometric manpower. Results : The new glasses supplied by army for ametropic soldiers were duplicated from the glasses they worn when entering the army. The spherical equivalent refractive powers of the conventional, ballistic protective and gas-mask insert glasses supplied for 37 ametropic soldiers were $-3.47{\pm}1.69D$, $-3.52{\pm}1.66D$ and $-3.55{\pm}1.63D$, respectively, and the spherical equivalent refractive power of full corrected glasses was $-3.79{\pm}1.66D$, which showed a significant difference(p<0.05). The distant corrected visual acuity measured at high and low contrast(logMAR) of conventional, ballistic protective and gas-mask insert glasses were $0.06{\pm}0.80$, $0.21{\pm}0.82$, $0.15{\pm}0.74$, $0.34{\pm}0.89$, $0.10{\pm}0.70$ and $0.22{\pm}0.27$, respectively, while the corrected visual acuity by full corrected glasses were increased to $0.02{\pm}1.05$, $0.10{\pm}0.07$, $0.09{\pm}0.92$, $0.26{\pm}0.10$, $0.04{\pm}1.00$ and $0.19{\pm}1.00$, respectively. There was a significant difference(p<0.05) except for the case of the low contrast corrected visual acuity of the conventional and gas-mask insert glasses. The procedure for ordering, dispensing, and supplying military glasses consists of 5 steps, and it was found that approximately two weeks or more are required to supply from the initial examination. Conclusion : The procedure of supplying the military glasses showed three issues: 1) a lack of refraction for prescription system, 2) relatively long length of time required for supplying the glasses, 3) an inaccurate power of supplied glasses. In order to solve those issues, in the short term, education is necessarily required for soldiers on the measurement of the refractive powers, and in the near future, further standard procedures for prescription of glasses as well as the securement of optometric manpower are expected.

Tooth transposition is the phenomenon in which two teeth in the dental arch are exchanged. The tooth most frequently involved in transposition is the permanent maxillary canine, especially with the first premolar. The etiology of transposition is still an enigma. Interchange of tooth germs, migration during eruption, genetic factor, local pathologic factors may be suggested as possible etiologic factors. There are three main options for treatment, which are the extraction of one of the transposed teeth, the alignment in the transposed position, the orthodontic movement of the teeth to their correct positions. If complete transposition occurred especially in mandible, alignment of teeth in the transposed position followed by occlusal reduction and esthetic restoration is usually recommended. The presented two-case report will describe the maxillary canine to the first premolar and to lateral incisor transposition with associated peg lateralis and retained primary canines. Although alignment the transposed teeth in original position is ideal treatment, it companies many complication as root resorption, alveolar bone destruction, gingival deheisence, etc. Therefore the treatment procedures in these case was relative cost-benefit effective method to both clinician and patients.
Purpose: This study was conducted to research effects of influence factors on stereopsis of induced aniseikonia in emmetropia. Methods: 20 college students (a mean age of $22.50{\pm}2.72$ years, 14 males, 6 females) were selected as subjects and all of them had no ocular disease or systemic disease, the refractive correction of spherical equivalent within ${\pm}0.50$ D, the corrected visual acuity of 1.0 or better and the aniseikonia values less than 1% by AWAYA. Subject's dominant eye was checked by Hole in card method and contact lenses of -7.00 ~ +7.00D were fitted to cause anisometropia in dominant eye or non-dominant eye, respectively. And then aniseikonia was induced with spectacles to correct refractive error by contact lenses. Stereopsis was measured by Random Dot Stereo Acuity Test with LEA symbols$^{(R)}$ (Vision Assessment Corporation$^{TM}$, USA). Results: Stereopsis was remarkably reduced by inducing aniseikonia, with induced aniseikonia in dominant eye, with higher diopter of wearing contact lenses to induce anisometropia, with spectacles lenses correction of minus power after fitting contact lenses with plus power and in case of men. Conclusions: It should be considered to correct anisometropia that aniseikonia could cause reduction of stereopsis.
