윤성운,성은영 한국영유아교원교육학회 2012 유아교육학논집 Vol.16 No.1

The purpose of this study was to analyze nursery school teachers’ recognition in the concept and practice of child care education, and to provide guidelines on child care education in nursery schools. For this purpose, ten nursery school teachers who worked in G province were selected and interviewed. The results of analysis on the characteristics of nursery school teachers’ recognition in the concept and practice of child care education were as follows:1) Nursery school teachers recognized the concept of caring as concession and help based on sympathy. 2) Nursery school teachers focused on social skills. 3) Nursery school teachers didn’t consider both sides of the care relationship: a caring person and a cared-for person. 4) Nursery school teachers limited their targets of caring to people and objects that were physically closer. 5) Nursery school teachers used verbal teaching and modeling strategies in child care education. Based on this information, the study suggests that teachers and programs 1) expand their targets of caring from familiar to unfamiliar things. 2) provide opportunities to exhibit care practice through care experience programs. 3) provide teacher education in helping teachers recognize in-depth care concepts. 본 연구는 유아기 배려교육의 개념과 실제에 대한 어린이집 교사들의 인식에 대해 알아봄으로써 효과적인 유아 배려교육 시행을 위해 현장에서 노력해야 할 내용 및 지도 방법에 대한 시사점을 제공하는 데에 목적이 있다. 이를 위해 현장에서 근무하는 교사들 10명을 반구조적 방법으로 일대일 심층 면담하였고 그 내용을 분석하였다. 그 결과 어린이집 교사들은 유아기 배려의 개념을 타인의 입장 이해를 바탕으로 양보하고 돕는 것이며 몸소 실천하여 그 과정에서 기쁨을 느껴가도록 하는 것이라고 인식하는 등 주로 사회적인 기술에 초점이 있었으나 배려자와 피배려자의 입장을 모두 고려하지는 못하였다. 또한 배려의 대상은 유아와 가장 가까운 인적자원과 물적 자원으로 한정짓고 있었고 배려 교육의 방법으로는 이야기나누기와 모델링 전략을 주로 사용하는 것으로 나타났다.

Availability of defect test algorithm that recognizes exact and standardized defect information in order to fundamentally resolve generated defects in industrial sites by giving artificial intelligence to SAT(Scanning Acoustic Tomograph), which previously depended on operator’s decision, to find various defect information in a semiconductor package, to decide defect pattern, to reduce personal errors and then to standardize the test process was verified. In order to apply the algorithm to the lately emerging Neural Network theory, various weights were used to derive results for performance advancement plans of the defect test algorithm that promises excellent field applicability.

The combination of two machining processes may result in the increase of productivity. This is an approach worthy to be tried, especially for the machining of so-called difficult to machine materials. In this study, ultrasonic machining(USM)is combined with electric discharge machining(EDM)for the machining of cemented carbide. It is confirmed through the experiments that this new machining process is effective in attaining a high material removal rate.

The authors analyzed 105 cases of spinal cord tumor in regarding to the age, sex, location and distribution, clinical presentation and postoperative outcomes. They were confirmed by pathologic study at the Kyung Hee Medical Cented from 1981 to 1991. The incidence of spinal cord tumors was slightly predominant in males. The most commom tumor was neurogenic tumor. The neurogenic tumor composed 43.8%(46 cases), and the rests were meningioma 15.2%(16 cases), metstasis 10.5%(11 cases) and others. The tumor were located most frequently in the thoracic area(31.4%) and in the intradural extramedullary space(56.1%). Most common initial symptom of spinal cord tumors were pain and it's mean duration was 8.3 month. The patients were assigned to one of four groups according to their neurologic deficit. About 66.6%(70 cases) of the patients were included in Groups Ⅰ and Ⅱ(mild neurologic deficit), and others were classified in Groups Ⅲ and Ⅳ(significant to sever neurologic deficit). Complete tumor removal was achieved in 70.4%(4 cases) of the patients, and subtotal removal was performed in 26.7%(28 cases), and biopay was performed in 2.9%(3 cases). Among the 105 patients, the postoperative outcomes on dischage were recovery in 36 cases(34.3%), improved in 45 cases(42.9%), stationary state in 12 cases(11.4%), and progression in 12 cases(11.4%).

본 연구에서는 국내에서 생산되는 에어콘용 팬의 진동해석을 위해 ESPI를 이용하였다. 기존의 진동해석 실험으로 많이 사용되는 가속도계를 에어콘용 팬에 직접 적응하는 데에는 형상의 제약 등으로 적용이 어려워 비접촉 진동해석기술을 요구하였다. 실험은 가진 장치를 이용하여 팬에 가진을 하고 ESPI를 이용하여 진동모드 및 고유주파수, 고유주파수의 범위를 검사하였다. 또한, 실험결과는 유한요소 해석과 비교되었으며, 실험결과로부터 실제 팬의 사용 회전수에서 제품의 신뢰성을 평가하였다. 본 연구에서 사용된 ESPI는 품질개선을 위한 재질변화 또는 형상변화 시 설계측면에서 효과적인 설계정보를 제공할 수 있으며, 기존의 진동해석 기술의 단점을 보관할 수 있으리라 사료된다. This paper propose electronic speckle pattern interferometry(ESPI) for reliability evaluation of electronic device. Especially, vibration problem in a fan of air conditioner, motor of washing machine and etc. is important factor to design the devices. But, it is difficult to apply previous method, accelerometer to the devices with complex geometry. ESPI, non-contact measurement technique applies a commercial fan of air conditioner to vibration analysis. Vibration mode shapes, natural frequency and the range of the frequency are decided and compared with that of FEM analysis. In mechanical deign of new product, ESPI adds weak point of previous method to supply effective design information.

윤성운,성은영 한국아동보육실천학회 2012 아동보육연구 Vol.8 No.1

본 연구는 만 5세 유아들에게 적합한 배려교육을 수행하기 위한 내용 및 방안을 모색하 기 위해 만 5세 유아들에게서 나타나는 행동 특성들과 배려교육의 어려움에 대한 어린이 집 교사들의 인식을 탐색하는데 그 목적이 있다. 이를 위해 현장에서 근무하는 교사들 10 명을 반구조적 방법으로 일대일 심층 면담하였고 그 내용을 분석하였다. 그 결과 교사들은 만 5세 유아들이 자기중심적이고, 자기주장이 강하며 조급함이나 말과 행동실천이 다른 것 등으로 인해 배려 지도가 어렵다고 인식하고 있었다. 또한 교사들은 배려에 대한 유아들의 반응에서 형식적인 반응과 무반응에 대해 지도가 필요하다고 인식하였고 배려 지도와 관 련하여 가장 어려움을 많이 느끼는 시기를 ‘학기 초’로 인식하고 있었으며, 가장 어려움을 많이 느끼는 활동은 ‘자유선택 활동’과 ‘전이 활동’인 것으로 나타났다.

龜裂材의 疲勞龜裂成長擧動에 관한 硏究

To evaluate the possibility of crack growth under the influence of cyclic stress, it is useful in aluminium alloy to employ the concept of threshold stress intensity factor range (ΔK_th) below which fatigue crack will not occur. Then the determination of the resistance of a material to fatigue crack growth relies on crack growth rate per cycle (da/dN) and amplitude of the stress intensity factor ΔK. The main conclusions are as follows. 1. Because the relation of da/dN-ΔK was described in a parallel straight line to the -axis of da/dN, region Ⅰ and Ⅱ are clearly distinguished with ΔK_th, and while the cyclic stress is continued, Nf is increased and crack is initiated, and the fracture arise from the increase of ΔK with the increase of da/dN. 2. It is reasonable to assume that ΔK is conveyed with the apparent crack arrest when it makes ΔK decrease to ΔK_th as the fracture toughness of material. 3. Test results coincide with the low critical equation of ΔK, and the value ofV_o is 0.5~2×10^-6㎜/cycle.
