Purpose: To estimate the baseline demographic and ocular characteristics of patients with optic nerve hypoplasia (ONH), and to analyze the different features and frequency of coexistent CNS abnormalities and pituitary hormone deficiency. Methods: The authors reviewed the medical records of the patients who were seen between January 1988 and July 2005. Eyes with disc-to-macula / disc diameter ratio of 3.0 or more were eligible. The study comprised 70 patients (45 male, 25 female) and the average age was 6.4 years. Results: Ocular manifestations included strabismus and nystagmus in 60 patients (85.7%) and 23 patients (32.9%), respectively. Eighty-four patients (87.5%) had visual acuity of 0.3 or less. Neuroradiologic examination of 27 patients revealed two with septo-optic dysplasia, two with pituitary hypoplasia, one with an absence of corpus callosum, one with diffuse encephalomalacia, one with a cerebral infarction in the right cerebral hemisphere, and one with a cerebellar injury. Of 12 patients who had undergone a clinical laboratory test, two had isolated growth hormone deficiency, one had a combined deficiency of growth hormone and gonadotropin and one had a combined deficiency of growth hormone and thyrotropin. Conclusions: Ocular features frequently associated with ONH are strabismus, nystagmus and poor vision. ONH is often associated with a wide variety of central nervous system abnormalities and pituitary hormone defect, so a systematic approach to patients with ONH is always recommended.

Purpose: To analyze the incidence, clinical characteristics and postoperative prognosis of simultaneous bilateral rhegmatogenous retinal detachment (SRD). Methods: We retrospectively analyzed the medical records of 22 patients who visited the Department of Ophthalmology, Yeungnam University College of Medicine, for treatment of SRD and who had been in regular surveillance for at least 6 months. Results: The incidence of SRD was 22 patients among 792 (2.8%). Eleven were male and 11 were female, and the average age was 27.6 years. Eighteen patients (81.8%) complained of visual disturbance and visual field defect of one eye, and myopia of more than -4.00D was noted in 30 eyes (68.2%). The size of the detached area was 2 quadrants in 19 eyes (43.2%). The most common type of retinal break was atrophic hole with lattice degeneration. The most common location of the break was the inferotemporal quadrant. The anatomical success rate of primary operation was 91.9% (34 of 37 eyes). Conclusions: Simultaneous bilateral rhegmatogenous retinal detachment was associated with young age, and myopia. As for the retinal break, the most common type was atrophic hole with lattice degeneration, and the most common location was the inferotemporal quadrant.

Purpose: To estimate the predictable factors of postoperative true ptosis remaining after squint surgery in patients with double elevator palsy (DEP), and to analyze the factors that must be considered before the correction of true ptosis. Methods: We retrospectively reviewed the medical records of 6 patients who had undergone strabismus surgery for DEP at the Department of Ophthalmology, Yeungnam University College of Medicine, between 1989 and 2003. The MRD (margin reflex distance) of paretic and nonparetic eye with each eye fixation, palpebral aperture, levator function, and Bell`s phenomenon were analyzed before and after squint surgery. Results: True ptosis was noted in 3 patients, one of whom underwent external levator resection. Postoperative Bell`s phenomenon improved in 2 patients who had poor Bell`s phenomenon preoperatively. Scleral show remained in 2 patients who underwent inferior rectus recession, and was taken into account before the correction of ptosis. Conclusions: Upper lid drooping in DEP patients is expected to be improved after squint surgery if preoperative MRD of paretic eye with paretic eye fixation has the same measured amount as that of non-paretic eye. MRD, Bell`s phenomenon and the amount of scleral show after the squint surgery should be carefully examined and assessed before the correction of residual ptosis.

김은아,이종국,김한성,Kim, Eun Ah,Lee, Chong Guk,Kim, Han Sung 대한소아청소년과학회 2003 Clinical and Experimental Pediatrics (CEP) Vol.46 No.2

저자는 우연히 발견된 무통성 종괴로 내원한 환아에서 소아과 영역에서 드문 Castleman 씨 병 2례를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. 림프절 종창으로 추정되는 무통성의 종괴를 보이는 환아에서는 Castleman 씨 병을 감별 진단으로 반드시 고려해 보아야 할 것이다. Castleman's disease is an atypical lymphoproliferative disorder of unknown origin. It has three histologic variants(hyaline vascular, plasma-cell, and mixed) and two clinical types(localized and multicentric). Some sufferers have constitutional symptoms and laboratory abnormalities such as anemia, hypoalbuminemia, hypergammaglobulinemia, and elevated erythrocyte sedimentation rate. The localized form is cured by complete surgical excision whereas the multicentric form is managed by prednisone and other immunosuppressor drugs. The prognosis of the multicentric form is worse than the localized form since malignancies and severe infections may lead to a rapidly fatal outcome. Castleman's disease has been rarely reported at pediatric age in Korea. We experienced two cases of Castleman's disease detected at 3 and 5 years of age. They were presented with painless enlargement of submandibulars and axillary lymph nodes but had no associated symptoms. The lesions were excised and diagnosed as Castleman's disease, and no recurrence was noted during follow-up periods.

결핵성 중이염은 매우 드문 질환이나 최근 결핵의 유병률이 증가하는 추세이므로 장기간의 항생제 치료에도 반응하지 않는 만성 중이염의 경우 결핵성 중이염의 가능성을 염두에 두어 감별진단 하여야 한다. 이런 관심은 조기 진단과 이에 따른 적절한 치료를 하게 되어 고막 파열, 청력 소실 및 안면신경마비와 같은 중한 합병증을 줄일 수 있을 것이다. Tuberculous otitis media is a very rare disease in extrapulmonary tuberculosis and in chronic otitis media nowadays. The characteristic signs seem to have altered from the past ones. And the suspicion index is very low that there is often a considerable delay prior to diagnosis. This might result in irreversible complications such as hearing loss, facial nerve paralysis and labyrinthitis. It is difficult to be defined by culture, so many patients with tuberculous otitis media are subjected to have surgery without a correct etiologic diagnosis. Therefore bacteriologic study of secretion and pathologic examinations of biopsied tissue are mandatory. We report one year and 11 months old boy with tuberculous otitis media having painful otorrhea and perforated tympanic membrane diagnosed by histologic finding and polymerase chain reaction(PCR). And we would like to emphasize the fact that tuberculous otitis media must be considered in the differential diagnosis of persistent suppurative otitis media despite appropriate antibiotic therapy considering the increasing tendency in incidence of Tuberculosis in Korea these days.

Metal three-dimensional (3D) printing is an important emerging processing method in powder metallurgy. There are many successful applications of additive manufacturing. However, processing parameters such as laser power and scan speed must be manually optimized despite the development of artificial intelligence. Automatic calibration using information in an additive manufacturing database is desirable. In this study, 15 commercial pure titanium samples are processed under different conditions, and the 3D pore structures are characterized by X-ray tomography. These samples are easily classified into three categories, unmelted, well melted, or overmelted, depending on the laser energy density. Using more than 10,000 projected images for each category, convolutional neural networks are applied, and almost perfect classification of these samples is obtained. This result demonstrates that machine learning methods based on X-ray tomography can be helpful to automatically identify more suitable processing parameters.

본 연구는 유아의 리더십 증진 방안의 일환으로 협동학습 모형에 근거한 숲 체험활동이 3-5세유아의 리더십을 증진시킬 수 있을 것이라는 가정을 검증하는데 목적이 있다. 이를 위하여 본 만 3,4세 유아 15명에게 협동학습 모형에 근거한 숲 체험 활동을 적용하였고, 비교집단 만 3, 4세 유아 15명에게는 3-5세 누리과정에 기초한 자유선택활동을 적용하였다. 또한 유아의 리더십을 측정하기 위하여 김경현(2007)의 AF분석법과 리더십 구성요소를 사용하였으며, 총 16주간 실험처치와 더불어 3회기에 걸쳐 반복측정을 실시하였다. 그 결과 첫째, 협동학습 모형에 근거한 숲 체험활동 집단과3-5세 누리과정에 기초한 자유선택활동 집단 간 처치회기에 따른 유아 리더십은 통계적으로 유의미한 차이가 있었다. 둘째, 협동학습 모형에 근거한 숲 체험활동 집단과 3-5세 누리과정에 기초한 자유선택활동 집단 간 처치회기에 따른 유아 리더십의 하위요인 간에도 통계적으로 유의미한 차이가 있었다. 결론적으로 본 연구에서는 협동학습 모형에 근거한 숲 체험활동이 유아의 리더십과 하위요소에 미치는 영향이 크다는 것이 입증되었다. As an effort to promote young children’s leadership, the aim of this study was to test the hypothesis ‘forest experience activities based on a cooperative learning model will enhance young children’s leadership’ by comparing them with play-centered integrated education activities. The subjects of this study were 15 three or four-year-old children for whom cooperative learning model based on a forest experience activities were applied, and 15 three or four-year-old children attending to whom free choice activities were applied. The children’s leadership was measured with Gyeong-Hyeon Kim’s AF analysis and leadership components. In order to analyze young children’s leadership behaviors based on the forest experience activities and play centered integrated education activities, the experimental treatment was done for 16 weeks’ experimental treatment was used. The results of this study for each research question are as follows. First, young children’s leadership during the treatment sessions was statistically significantly different between the cooperative learning model forest experience activity group and the free choice activity group. That is, young children’s leadership level was higher in the cooperative learning model forest experience activity group than in the free choice activity group. Second, a statistically significant difference was observed also in the sub-factors of leadership during the treatment sessions between the cooperative learning model forest experience activity group and the free choice activity group. In conclusion, it was proved shown in this study that ‘forest experience activities based on a cooperative learning model have a significant effect on young children’s leadership. The educational implication of this finding is that young children’s leadership may be enhanced through forest experience based on a cooperative learning model.

김은아(Kim, Eun-Ah) 한국열린유아교육학회 2018 열린유아교육연구 Vol.23 No.3

본 연구는 예비유아교사들이 인식하고 있는 결혼에 대한 가치, 이에 대한 학년별 차이 그리고 좋은 부모에 대한 역할기대를 분석하는데 그 목적이 있다. 먼저 결혼에 대한 가치를 분석하기 위하여 W대학에 재학 중인 예비유아교사 3학년 56명과 G대학 2학년에 재학 중인 예비유아교사 30명, K대학 1학년에 재학 중인 예비유아교사 55 총 141명을 대상으로 설문을 실시하였다. 또한 예비유아교사가 인식하고 있는 좋은 부모에 대한 역할기대를 분석하기 위해 예비유아교사 20명을 대상으로 개념도 분석을 실시하였다. 그 결과 예비유아교사는 결혼과 자녀에 대해 전반적으로 긍정적으로 인식하고 있었으나 양육에 대해서는 경제적 문제로 다소 부정적인 견해를 가지고 있는 것으로 분석 되었다. 또한 각 문항에 대하여 학년 별 차이를 분석하였는데, 대부분의 문항에서 학년 별 인식의 차이가 있는 것으로 나타났다. 더불어 예비유아교사가 인식한 좋은 부모는 ‘존중해 주는 부모’, ‘모범적인 부모’, ‘지지해 주는 부모’, ‘친구 같은 부모’로 분류 되었다. 이를 바탕으로 결혼에 대한 가치 형성과 부모역할수행에 관련하여 예비부모교육의 방향성에 대해 논의 하였다. The purpose of this study is to analyze value of marriage, difference in level of awareness of such value based on grades, and role expectation about ‘good parenting’ perceived by pre-service kindergarten teachers. In order to analyze the value of marriage, 56 pre-service kindergarten teachers who are attending W University, 30 pre-service kindergarten teacher attending G University, and 55 pre-service kindergarten teachers attending K University, in total of 141 subjects were included in survey. In addition, concept map analyze was carried out on 20 pre-service kindergarten teachers for analysis on the role expectation about ‘good parenting’. The results were as follows: pre-service kindergarten teachers showed positive opinion on marriage and children but negative opinion on nurturing due to financial cause reasons. Also, difference level of perspective toward each questionnaire was analyzed for each grade and such difference appeared to exist by the grades. Furthermore, the ‘good parenting’ perceived by the pre-service kindergarten teachers was categorized as ‘apprising parents’, ‘exemplary parents’, ‘supportive parents’, and ‘friendly parents’. On the basis of these results, this study discussed the formation of values and the educational direction for pre-parents.

This study attempted to investigate the influence of the reducing agent and formulation of the agent I on wave formation efficiency and hair changes during heat perm on virgin hair through morphological analysis. For this, a total of 6 different formulations in cream and liquid types were prepared, using thioglycolic acid (TGA), cysteine and cysteamine for the agent I, and applied to both control (untreated) and experimental groups. Then, wave formation efficiency and hair changes after heat perm were examined through morphological analysis, and the results found the followings: In terms of wave formation efficiency, the TGA cream type (VH-A1) was the highest while the cysteine liquid type (VH-B2) was the lowest. Regarding morphological analysis of hair, hair density and cuticle thickness were analyzed, using methylene blue (MB) absorbance and FEM-SEM respectively. In addition, the surface and microscopic structure of cuticle were observed with SEM and AFM each. In terms of hair damage, ‘VH-A1’ was the highest while ‘VH-B2’ was the lowest. In addition, a cream type was greater than a liquid type in terms of hair damage. The above results confirm that the ingredients and formulation of the reducing agent for the agent I during heat perm have an influence on wave formation efficiency and hair through morphological analysis. Therefore, it is anticipated that they would be helpful in minimizing hair damage and enhancing customer satisfaction through the efficient selection and application of the reducing agent for the agent I.
