Recent advances of neuroimaging and electrophysiological monitoring technique have contributed in improving the surgical outcome of frontal lobe epilepsy. The authors have analysed 36 consecutive cases of intractable frontal lobe epilepsy that were treated at our institute between September. 1992 and December, 1995 to determine the clinical, electrophysiological, and neuroimaging characteristics as well as to delineate the efficacy of surgical treatment in improving the seizure outcome. The patients consisted of 19 males and 17 females. The mean age of the seizure onset and the mean duration of epilepsy were 14.9 and 11.6 years, respectively. Magnetic resonance imaging(MRI) showed no lesion in 9 patients and pathological lesions in 27 patients. The types of the lesions observed included primary brain tumor, mostly low-grade glioma in 10 patients, cortical dysplasia in 4, posttraumatic scar in 4, neocortical gliosis in 3, cyst in 3, and postencephalitic atrophy in 3. Intracranial recordings were performed in 23 cases to determine the epileptogenic zone. The surgical outcome was graded according to Engle’s Classification as Class A in 20 patients. Class B in 2, Class C in 9, and Class D in 5. The surgical outcome was promising regardless of the presence or the absence of the lesion on MRI, invasive recording, age of seizure onset, and duration of epilepsy.

Background : This investigation was to perform the epidemiological surveillance and genetic analysis on respiratory viral agents from children with acute respiratory infections in Gwangju. Materials and Methods : For this study, 3,695 specimens obtained from patients with acute respiratory infections were collected by collaboration with pediatric hospitals in Gwangju between 2005 and 2007. Specimens were screened for 8 respiratory viruses including influenza viruses (IFV), human rhinoviruses (HRV), human coronaviruses (HCoV), adenoviruses (ADV), parainfluenza viruses (PIV), human enteroviruses (HEV), respiratory synthitial viruses (RSV) and human bocaviruses (HBoV). Respiratory viruses were detected using multiplex (RT) PCR with viral specific primers. Results : Out of 3,695 specimens, the ratio of virus detection was 24.9% (919). Overall, HRV (35.5%) and IFV (34.9%) were the most common viruses found, followed by HBoV (14.8%), HCoV (10.6%), RSV (3.7%), ADV (3.4%), PIV (3.2%) and HEV (3.0%). In addition, multiple infections were detected in 80 patients (8.7%). When the prevalence was analyzed according to season, HBoV, IFV and HCoV showed two epidemic points in late spring and early winter. ADV, HRV, RSV PIV and HEV, however, were all found to have only one epidemic point, with RSV being most common during winter and the others being most prominent during spring. Conclusions : Through this epidemiological surveillance, the respiratory viruses prevalent in children in Gwanaju area were investigated. We strongly recommend the development of nationwide policy for the management of prevalent respiratory virus that includes long term collection of data and samples, vaccine development and prevention education of the misuse of antibiotics.

The common strategy of speed control of single-phase induction motors depends mainly upon controlling the applied voltage on the motor. Changing the applied voltage on the motor can be effected by several techniques. Some on these techniques auto-transformers or adding extra winding, as required, to either the main or auxiliary winding. The other approaches use power electronic devise such as TRIAC. Each one of these schemes has and demerits. Single-phase induction motors are always small and are seldom built in sizes over fractional horsepower ratings, In view of this, they are deprived from controlling their speed by expensive drives which employ frequency control; a matter which offers a wide range of speed control. However, if the input supply frequency to a single-phase induction motor is controlled by a single controlled forced commutated device. Certainly, the event will be a remarkable achievement. This approach is the essence of the present paper. The paper presents a new drive for single-phase induction motor. This drive bridge rectifier connected with the stator in a non-conventional fashion. The speed of the single-phase induction motor is controlled by controlling the chopping frequency of the chopper switch. The attractive feature of the drive is that it effects doth frequency and do chopping simultaneously. The drive performance has received both theoretical and experimental investigation.

Chunk를 이용한 초등학교 어휘학습 연구

김수진,손근원 韓南大學校 敎育硏究所 2010 교육연구 Vol.18 No.3

The purposes of this paper are two-fold: This paper first shows that it is necessary to introduce chunk-based teaching methods for effective vocabulary teaching at elementary school levels and then suggests chunk based teaching methods applicable at the authentic classroom situations. Developing communicative competence surely includes the extension of vocabulary power and it is significant to use effective vocabulary teaching methods in classrooms. As is well known, vocabulary learning faces a lot of problems if it is not implemented in meaningful contexts. Hence it is vital for the language learners to learn and use chunks, the meaningful units of words, in natural contexts from the beginning stage. Based on these considerations, this paper critically examines the chunk expressions in the elementary English textbooks and reviews the vocabulary teaching methods currently recommended at elementary schools. Finally this paper suggests useful vocabulary teaching strategies using chunks which are applicable at elementary school levels. 이 논문은 초등학교에서 어휘를 효율적으로 가르치기 위해서 chunk를 이용한 교수법을 도입하는 것이 필요하다는 것을 보이고 나아가 실제로 적용가능한 chunk 이용 교수방법을 제안하는 것을 목적으로 한다. 의사소통능력의 신장은 어휘력 확장과 불가분의 관계에 있다. 따라서 효율적인 어휘학습방법을 교실상황에서 사용은 의미 있는 일이다. 그러나 어휘를 개별적으로 학습하는 경우에 여러 가지 문제점이 생긴다는 것이 주지의 사실이므로 이를 극복하기 위해 처음 영어를 배우는 단계에서부터 학습자들이 의미단위화된 어휘구인 chunk를 자연스럽게 접하고 익히도록 하는 것이 필수적이다. 따라서 본 연구는 기존 교수법에서의 어휘지도방법을 살펴보고 chunk 중심 어휘지도가 필요함을 수립시킨 후, 이것이 왜 초등 영어교육에서도 필요한가를 살펴볼 것이다. 또한 초등영어교과서를 분석하여 어떤 종류의 chunk들이 수록되어 있는지, 또 이들을 어떻게 가르치도록 제시되어 있는지를 점검하고 초등영어교육에서 활용할 수 있는 chunk 중심의 어휘지도 활동을 구체적으로 제시하여 볼 것이다.

This research have been made to define how the IADL (Instrumental Activity of Daily Living) performance and the subjective health index of the Aged are affected by their residential circumstance, gender and age, and how deeply these two factors are related and interact. For the period of June 1 to July 31, 2000, we had conducted a questionnaire and direct interview with 693 persons over age sixty-five (65) in Daejon and in other adjacent area, grouping into three different residential types The Aged living at home, The Aged living at welfare facilities and The Aged living alone, and studied on how the IADL performance and the subjective health index of the Aged are influenced and interact as per their characteristics, daily activity and mentality. We had analyzed all the data obtained through this research by the method of : - analysis of frequency as per specific factors by SPSS 10.0/PC+, - x^2 test, - t - test, - ANOVA, - multiple regression analysis by factors. The research concludes followings : a. It appears that the three (3) factors such as gender, age and residential circumstance of the Aged deeply affect the IADL performance and subjective health index of the Aged. (p<0.01) b. With regard to IADL performance of the Aged by the gender, it was analyzed that the female-Aged gains 23.8 point on average, which shows the performance of the female-Aged is less independent. (p<0.01). In addition, it was also found that the IADL performance is becoming less and less independent following their age increasing. In analyzing IADL performance by the residential type, it appears that the Aged living at welfare facilities gains the lowest 21.5 points and is least independent. It was also found that the Aged living at welfare facilities need some assistances from others for their performing IADL. (20-24 point) (p<0.001) c. With regard to the subjective health index of the all-Aged participated in this research, the analysis indicates 8.8 point and this is considered as a point of general standard (7-10 point). In analyzing this index by the gender, the female-Aged gains only 8.6 point which explains a lot of female-Aged consider they are not really healthy. (p<0.001) In analyzing this index by the residential type, the Aged living at welfare facilities and the Aged living alone gain the comparatively lower point, - respectively 8.4 point for the Aged living at welfare facilities and 8.8 point for the Aged living alone. The Aged living at these two residential types express they are obviously in a bad situation of health. (p<0.001) d. With regard to the factors affecting the IADL performance and the subjective health index of the Aged, it was analyzed that the IADL performance can largely be affected by the factors such as depression, frequency of going-out and age rising, and that the subject health index can also deeply be affected by depression, pain and by how much they are satisfied with their current living conditions. e. It was analyzed that the interacting between the IADL performance and the subjective health index is not that strong but even weak. As a result, we were able to conclude that the IADL performances is less independent in case of the female-Aged, the Aged living at welfare facilities, and following the age rising. As for the subjective health state the Aged themselves are aware of, we concluded that the female-Aged, the Aged living at welfare facilities and the Aged living alone, are more critical about their health. From this research, we were able to realize that, when the OMT (Orthopedic Manual Therapy) needed, the physical therapists are really required to have a correct and cautious understanding of the situation in which the aged persons are, and take care of them with more concerns and more improved treatment.

김근수,김영수 대한신경외과학회 1996 Journal of Korean neurosurgical society Vol.25 No.5

Posterior cervical fusion is still the procedure of choice in the cases of spinal instability caused by flexion injuries. Halifax interlaminar clamp system can be used whenever posterior cervical fusion is to be performed. Thirty one consecutive patients were treated with Halifax interlaminar clamp for cervical instability from Jan. 1991 to Jan. 1995. We followed up all of the cases for more than one year. All of the twenty six mid and low cervical fixations showed immediate and long term stability and there were no neurological complications, Two cases among the five C1-2 fixations were failed due to loosening of clamps. Fifteen cases of mid and low cervical fixations showed facet sclerosis and interbody fusion on the plain X-ray films after more than one year.

가정배경이 직업포부에 미치는 영향 : 가족 내 사회자본의 역할을 중심으로

신수영,김경근 안암교육학회 2012 한국교육학연구 Vol.18 No.1

본 연구에서는 한국교육개발원의 한국교육종단조사(KELS) 데이터를 사용하여 중학생의 직 업포부 결정요인을 분석하였다. 일반화된 위계적 선형모형(HGLM)을 사용한 분석 결과, 중 학생의 직업포부 형성에는 성별, 학업성취, 교육포부, 학업효능감 등이 중요한 역할을 수행 하는 것으로 밝혀졌다. 이러한 변수들 외에 하위직 직업포부의 형성에는 부모 학력과 부모 의 교육적 관여가 핵심 영향요인으로 작용하고 있는 반면, 상위직 직업포부는 가구소득과 부모의 기대의 영향을 받는 것으로 드러났다. 이 같은 연구결과를 통해 직업포부에 대한 가 정배경의 강력한 영향력을 재확인할 수 있었지만, 교육포부, 학업효능감, 그리고 부모의 기 대나 교육적 관여와 같은 가족 내 사회자본 등을 통한 개입의 여지는 남아 있는 것으로 보 인다. 단, 이러한 요인들 역시 가정배경의 영향으로부터 자유롭지는 못하기 때문에 계층 간 직업포부 격차를 완화하기 위한 정책대안을 모색할 때는 이 같은 한계가 적절히 감안될 필 요가 있다. This study examines the relationship between family background and occupational aspiration, using representative data for junior high school students from the 2005 Korean Education Longitudinal Study(KELS). As a result of Hierarchical Generalized Linear Models analysis, the authors found that student's gender, academic achievement, educational aspiration, and academic efficacy play an important role in shaping occupational aspiration of junior high school students. In addition to these variables, with those students having aspirations for a mid-level occupation as the reference group, parent's level of education and parental involvement in education were found to be statistically significant factors for students when deciding a low-level occupation. In contrast, family income and parental expectation were found to be deciding factors for students who aspire for a high-level occupation. The findings suggest that family background itself plays a major role in shaping the level of occupational aspiration. Meanwhile, there might remain some room for policy intervention through boosting educational aspiration, academic efficacy, and such social capital within family as parental expectation and parental involvement in education. Since these factors are not free from family background, however, this limitation should be properly taken into account when developing policy alternatives to bridge occupational aspiration gaps between social classes.

The authors examined human immunity indicators such as CD4, CD8, Natural Killer(NK) cell, IgG, IgA, and IgM, and heavy metals such as Pb, Cr, Cd to evaluate the health hazard of welders. We selected total 126 male subjects, 60 welders who had more than 5 year working history as an exposure group, and 66 office workers and medical college students as a control group. This immunity evaluation approach is the first newly designed study that has never been tried in past studies on welder's heath evaluation. And the results were as follows. 1. Total lymphocyte count of peripheral blood was significantly higher in welder group, 2,615±650 ea/㎕ compared with 2,368±681 ea/㎕ in control group(p>0.05). 2. The proportion of CD4, CD8, NK cell in welder group was 37.5±9.4%, 24.0±8.8%, and 21.0±9.5%, respectively, and 35.5±6.5%, 25.0±6.9%, and 19.6±8.8% in control group. CD4 and NK cell were slightly higher, and CD8 was slightly lower in welder group. but there was no statistical significance between two groups(p≥0.05). 3. IgG, IgA, and IgM in welder group were 15.9㎎/㎗, 2.7㎎/㎗ and 1.5㎎/㎗, respectively, and 15.6㎎/㎗, 2.9㎎/㎗ and 1.7㎎/㎗ in control group. There was no statistical significance between two groups(p≥0.05). 4. Blood lead, cadmium and chromium concentrations were 4.2±1.8㎍/㎗, 0.4±0.38㎍/㎗, 1.2±0.6㎍/㎗ in welder group and 3.2±1.7㎍/㎗, 0.44±0.29㎍/㎗, 1.1±0.6㎍/㎗ in control group, respectively, and these value were within normal ranges.
