옥재진,정윤경 한국초등상담교육학회 2022 초등상담연구 Vol.21 No.1

본 연구의 목적은 학령전기의 부정정서표현에 대한 부모의 지지반응이 정서 공감을 매개로 학교폭력 가해동조 행동에 영향을 미치는지 검증하는 것에 있다. 이를 위해 서울․경기의 초 등학교 5․6학년 334명을 대상으로, 유아기의 부정정서표현에 대한 양육자의 반응(CCNES-회 고형) 및 공감(EQ-C), 학교폭력 주변인 행동반응(PRQ)을 설문하였다. 분석결과, 아동의 부정정 서표현에 대한 부모의 지지반응은 인지적․정서적 공감 모두에 정적으로 유의한 상관이 있 었다. 또한 인지적 공감과 가해동조 행동은 상관이 없었지만, 정서적 공감은 가해동조 행동 과 부적상관을 보였다. 아동의 부정정서표현에 대한 부모의 지지반응은 학교폭력 3가지 주변 인 행동과 각각 상관이 없었고, 비지지반응은 가해동조반응에서만 정적상관이 나타났다. 끝 으로 학령전기 아동의 부정정서표현에 대한 부모의 지지반응은 정서적 공감을 매개하여 학 교폭력 가해동조 행동에 부적인 영향을 미치는 것으로 나타났다. The purpose of this study was to investigate the mediating effect of child’s emotional empathy on the relationship between parental reactions to children’s negative emotional expression and the bullying-supporting behaviors. To this end, 334 fifth and sixth graders in elementary school were asked to complete questionnaires including Coping with Children’s Negative Emotion Scale, Children’s Versions of the Empathy Quotient and Participant Role Questionnaire. As a result of the analysis, parents’ supportive responses to negative expressions were significant correlation to both cognitive and emotional empathy, and bullying-supporting behaviors was not correlated to cognitive empathy, but was significant correlated to emotional empathy. In addition, in the case of emotional empathy, female students were significantly higher, and male students were significantly higher in bullying-supporting behaviors. Finally, supportive responses to expression of negative emotions were found to have an adverse effect on the role of bullying-supporting behaviors mediating emotional empathy. In particular, the influence of supportive responses on emotional empathy was higher in female students than in male students, and the influence of emotional empathy on bullying-supporting behaviors was higher in male students. Consequently, this study has implications in proposing a fundamental solutions to peer bullying.

지난해 전체시장 10%로 성장기반 마련, 2002년 디지털복사기의 춘추전국시대 예상 - 복사기 시장의 동향 및 전망

옥재진 한국광학기기산업협회 2002 光學世界 Vol.14 No.1

지난 2001년 복사기 총 시장은 IMF 이전 수준은 완벽하게 회복하지 못했으나 디지털복사기는 전체시장의 10$\%$를 차지하며 본격적으로 성장할 수 있는 기반을 마련했다. 물론, 여전히 아날로그복사기가 각 메이커들의 가장 두터운 구매층을 이루겠지만 2002년에는 무엇보다도 디지털복사기의 급성장이 예상된다.

The present study is designed to investigate the mediating effect of child empathy on parental reactions to children's negative emotional expression and the defender's role in bullying. To this end, 384 fifth and sixth graders were asked to complete questionnaires including Coping with Children's Negative Emotion Scale(CCNES), Children's Versions of the Empathy Quotient(EQ-C) and Participant Role Questionnaire(PRQ). Our results reveal that supportive parental reactions to children's negative emotion has a significant positive effect on both cognitive and emotional empathy. Also, empathy is significantly related to children's defense responses for victims and is negatively related to bullying-supporting and onlooking behaviors. In particular, it was found that cognitive empathy did not have a significant effect on the bullying-supporting responses both in male and female students, whereas emotional empathy had a significant impact on bullying attitudes. Finally, supportive responses for children’s negative emotional expressions were found to influence the defense responses of bullying victims through building empathy in children. 본 연구는 학령전기의 부정정서표현에 대한 부모반응이 공감능력을 매개하여 또래 괴롭힘에서 피해자 방어 행동반응에 영향을 미치는지 검증하는 것에 그 목적이 있다. 이를 위해 서울․경기 지역의 초등학교 5-6학년 384명이 유아기 시절의 부정정서표현에 대한 양육자의 반응 및 공감, 또래 괴롭힘 참여역할 행동반응에 관한 설문에 참여하였다. 분석결과, 부정정서표현에 대한 부모의 지지반응은 인지적․정서적 공감능력 모두에 정적으로 유의한 영향을 미쳤다. 공감능력은 피해자 방어반응에 정적으로, 가해동조 및 방관 반응에 부적으로 유의한 영향을 미쳤다. 특히 인지 및 정서적 공감능력 모두 방어자 행동반응에 정적인 영향을 미쳤고, 가해동조반응에는 정서적 공감만이 부적으로 유의한 영향을 미쳤다. 끝으로, 부정정서표현에 대한 지지반응은 공감능력을 부분 매개하여 또래 괴롭힘 방어자 역할에 정적으로 영향을 미치는 것으로 나타났다. 이에 학교폭력의 근본적인 해결방안으로 생애 초기의 부모의 정서사회화 행동이 갖는 의의를 논하였다.

The palatal fracture results in deformity of the midface, as well as change in occlusion. However, no report was found on the incidence, treatment and results of palatal fracture in Korea. A retrospective review was done over 6 years and 11 patients(6.5%) with palatal fracture were determind out of 168 patients who had midfacial bone fractures without nasal bone fracture. According to the Hendrickson's classification, the number of patients with specific types of palatal fracture was described as follows; sagittal(2 cases), parasagittal(2 cases), para-alveolar(3 cases), transverse(3 cases) and complex(1 case). Le Fort Ⅰ(6 cases), Le Fort Ⅱ(7 cases) and mandible(6 cases) fractures were also associated. Open reduction and internal fixation was applied to all patients. Internal fixation consisted of pyriform or alveolar ridge stabilization and maxillary buttress stabilization. The rigid palatal vault stabilization was applied in one patient with midline split of the palate. The duration of intermaxillary fixation was shortened to less than 3 weeks from 4 to 6 weeks with rigid fixation. The palatal splint was used temporarily before internal fixation. All the patients showed good bony union and satisfactoryocclusion postoperatively. Open reduction and internal fixation showed satisfactory results from the aspects of stability, occlusion, patient convenience and final aesthetics. The following treatment model for palatal fracture according to the fracture type is proposed; 1) Alveolar type - close reduction or open reduction and selective alveolar ridge fixation and selective application of palatal splint, 2) Sagittal type - open reduction and internal fixation of the alveolar ridge, maxillary buttress and palatal vault. 3) Parasagittal type - open reduction and internal fixation of the pyriform aperture and maxillary buttress, as well as selective fixation of the palatal vault. 4) Para-alveolar type - open reduction and internal fixation of the alveolar ridge and maxillary buttress. 5) Complex type - open reduction and internal fixation of the alveolar ridge, maxillary buttress, pyriform aperture and continuous use of a palatal splint to bony union. 6) Transverse type - open reduction and internal fixation of the alveolar ridge and maxillary buttress.

The 635-nm low-level laser therapy was reported to "liquefy" or release stored fat in adipocytes by causing a transitory pore in the cell membrane to open, which permitted the fat content to go from inside to outside the cell. But some data do not support the belief that low-level laser therapy treatment before lipoplasty procedures disrupts tissue adipocyte structure. The purpose of this study was to determine the effectiveness of low-level laser- assisted liposuction. The use of low-level laser-assisted lipoplasty was evaluated in a series of 90 cases. There were 2 treatment groups in the clinical study. Subjects in the test group(39 patients; 31 thighs and 17 abdomen) received only liposuction on one side and laser-assisted liposuction on the other side during early 1liter aspiration time. 51 patients in the operated group received laser-assisted liposuction on both side. After adequate infiltration was obtained in all targeted body areas, a 635-nm electric diode laser was applied to the targeted areas for 12 to 15 minutes to liquefy the fat which was extracted immediately after laser treatment. On the side which received laser-assisted liposuction of the 39 test-group patients, we could gain much fat component(71±7.2 vs 63±8.6%) and it took short time(26±5.7 vs 31±7.7 minutes). Postoperative recovery was rapid, and complications were minimal. Low-level laser-assisted lipoplasty can be a valuable adjunctive tool for the performance of lipoplasty.

The reverse lip design: a design for safe and effective abdominoplasty

고주영,김륙성,옥재진,정보람,배성환 대한미용성형외과학회 2021 Archives of Aesthetic Plastic Surgery Vol.27 No.4

Conventional abdominoplasty includes the removal of an ellipse-shaped section of abdominal tissue between the umbilicus and mons pubis. However, this method can result in tension of the undermined flap, especially in the midline. To address this problem, we present reverse lip design as a modified method that also has aesthetic advantages. The reverse lip design entails a longer lower flap edge while preserving the triangular tissue in the vascularly stable pubis area. These markings create an image of a reverse lip shape with a cleft at the bottom of the lower markings. After typical lipoabdominoplasty is performed, redundant waist tissues can easily be pulled inward and downward. The reverse lip design abdominoplasty demonstrated no complications and required no further revisions after the procedure. Patients were generally satisfied with the aesthetic improvements in their body shape. They were also able to return to their routine activities approximately 1 week after the operation while wearing a supporting undergarment. This modified abdominoplasty using the reverse lip design reduces low midline tension of the undermined abdominal flap while enhancing body aesthetics with a slimmer waistline, leading to higher patient satisfaction.

How to get the Best Results in Transaxillary Breast Augmentation with Anatomic form Stable Implants: Pocket Shapes, Insertion, and Maintenance

박진석,임중혁,옥재진,선상훈,이영우,박성철,설철환,윤원준 대한미용성형외과학회 2013 Archives of Aesthetic Plastic Surgery Vol.19 No.2

Although IMF incision is known the best way for anatomic implant, most Korean doctors and patients hesitate IMF incision. Anatomic form stable implants have some benefits such as less prominent upper pole,less wrinkles and ripples, and less rupture rate than round cohesive type I implants. However more concern is necessory for placing the anatomic implants. The Korean Academic Association of Breast Surgery(KAABS)planned to support some tips for using anatomic form stable implants through axillary incision. The KAABS gathered and analyzed the concepts of Korean plastic surgeons who have experienced transaxillary breast augmentation with anatomic form stable implants. The KAABS requested them of their concepts of 9 basic categories: entrance dissection, pocket dissection, lubricant, inserting aids, skin protector, inserting direction,suction drainage, dressing, compression garment, and their key considerations. Eight expert surgeons suggested their own cutting edge methods of transaxillary breast augmentation with the anatomic form stable implant, however each surgeon should find his or her own method. Authors and KAABS hope that these developing and incomplete concepts help beginners to find their own concepts.
