  • 본 연구의 목적은 물리 외 교과서의 물리 내용 설명이 학생들의 물리개념 형성에 미치는 영향에 대하여 조사하는 것이다. 본 연구를 위해 부산에 있는 두 중학교에서 각 39명의 학생들로 구성된 한 학급씩을 선정하였으며, 학생들의 개념 조사를 위해 두 종류의 검사 도구를 개발하였다. 검사 도구는 A는 물리 외 교과서의 물리 내용에 관한 설명을 읽은 후에 학생들의 개념을 조사하기 위한 것이고, 검사 도구는 B는 똑같은 물리적 현상에 대해 물리 교육 전문가에 의해서 물리학적으로 이해가 가능하도록 다시 진술한 설명을 읽은 후에 학생들의 개념을 조사하기 위한 것이다. 각 학급에 두 검사 도구 모두를 적용시켰다. 이때 공평한 조사를 위해 한 학급에는 검사 도구 A를 적용한 후 검사 도구 B를 적용하였고, 다른 학급에는 검사 도구 B를 적용한 후 검사도구 A를 적용하였다. 본 연구의 결과는 다음과 같다. 두 학급 모두에서 물리 교육 전문가에 의해서 재진술된 설명에 대한 학생들의 이해도가 물리 외 교과서의 설명에 대한 이해도 보다 더 높게 나타났다(p< .01). 이것은 물리 외 교과서에서의 모호하고 바르지 못한 물리 개념의 설명이 학생들의 오개념을 유발할 가능성이 있으며, 적절치 못한 문장의 표현 및 용어의 선택, 애매한 문장의 문법적인 구조가 물리 개념을 올바르게 이해하는데 방해가 됨을 알 수 있다. 또한 적절치 못한 예와 잘못된 그림을 제시하는 것이 오개념을 형성시킬 가능성이 높다고 볼 수 있다. 그리고 물리 교과서에 사용하는 용어와 물리 외 교과서에서 사용하는 용어가 다른 것이 학생들의 혼동을 야기 시킬 수 있다는 것을 알 수 있다.

  • Purpose: This study examined the effects of a positioning education program through the brochure or oral explanations for the parents of premature infants with a brain lesion and investigated the satisfaction level of physical therapy of parents of premature infants with a brain lesion. Methods: Forty parents of premature infants with a brain lesion participated in this study. The recruited premature infants were randomized into groups A (n=20) and B (n=20) for the purpose of the positioning education method through brochure or oral explanations. The level of satisfaction and recognition for the positioning education program was investigated by the parents of 12 month old infants. The gross motor function, measure-88, was examined at three months, six months, nine months, and twelve months of the corrected age. Results: No significant differences in the recognition of the position education program, level of satisfaction of the environment, and the attitude of the therapist were noted (p>0.05). Significantly high levels of satisfaction with the program of group B given the brochure were noted. The gross motor function measure-88 was also similar in both groups (p<0.05). Conclusion: This study suggests that the parents were satisfied with the positioning education program of the brochure. The differences in educational methods did not affect the development of premature infants.

  • Background : This study was designed to assess the effects of information on the satisfaction of parents and families whose children underwent elective surgery in the Pediatric Operating Room. Methods : We measured parent and family satisfaction with information given before and after offering informational interventions. The data were collected from 510 patients parents and families whose children had undergone elective surgery in the Pediatric Operating Room of Seoul National University Hospital in Seoul. South Korea. The data collection ran from May 3. 1999 to May 30. 1999 and from September 6, 1999 to September 30, 1999. The research instrument consisted of four categories (pre-operative period, intra-operative period, post-operative period, others) and 24 questionnaires. SPSS was used to analyze the data. Results : The major findings of this study are summarized as follows: 1. Before surgery, the satisfaction with the following was increased: the explanations of the necessary preparation for the surgery (6.0%), the time the patient would enter the operating room (20.6%), the operative procedure (2.0%), and the use of the waiting room (10.0%). 2. During the operation, the satisfaction with the situation board (15.1%), public announcements in the waiting room (8.4%), and the answering of the families questions (12.2%) was increased. however, the satisfaction with the surgeons explanations of the surgical outcomes decreased by 8.3%, even though the frequency of these explanations increased by 5%. 3. After surgery, the satisfaction with the following was increased: the explanations of patient's status of recovery(10.3%) the time the patient would be moved from the recovery room (17.6%), how the patient would be transferred to the ward (19.2%), and post-operative care (6.3%). Conclusion : Based upon the above findings, we concluded that pre-, intra-, and post-operative informational interventions were effective in increasing the satisfaction of the parents and families of children undergoing elective surgery.

  • 본 연구에서는 한국사회 구성원의 빈곤원인 인식 유형 및 분포, 주요 빈곤원인 인식의 결정양상에 대한 분석을 통해 한국사회가 지닌 빈곤에 대한 사회적 태도의 이해를 제고하고자 하였다. 본 연구의 분석에는 빈곤원인 인식 항목이 새롭게 추가된 8차년도 한국복지패널조사자료를 활용하였으며, 분석결과에서는 한국사회의 빈곤원인 인식이 개인책임 인식(individualism), 사회구조책임 인식(structuralism), 운명책임 인식(fatalism) 등의 세 가지 유형으로 분포하고 있으며, 한국사회에서는 빈곤원인을 개인책임으로 인식하는 성향이 높음을 확인할 수 있었다. 한편, 빈곤원인 인식의 양상은 인구사회학적 특성, 사회경제적 수준, 가치태도 등에 따라 유의미한 차이가 있음을 또한 확인할 수 있었다. 개인책임, 사회구조책임, 운명책임의 빈곤원인 인식에의 결정양상은 일부 차이를 보였지만, 대체로 가치태도 변수들이 주요하게 영향을 미치는 것으로 나타났다. 본 연구결과는 한국사회 빈곤원인 인식의 실태와 특성을 보여주는 바로, 특히 빈곤을 개인책임으로 인식하는 성향이 높다는 분석결과는 한국 사회복지의 낙후성이 이와 같은 사회의식에 기반한 것일 수 있음을 시사하여 준다. 아울러, 빈곤원인 인식의 결정에서 가치태도의 주요한 영향은 복지국가 발전의 토대 조성에 사회문화적 맥락에도 정치적, 정책적 관심이 제고되어야 함을 시사하여 준다.

  • Objectives NJ is being used to treat inflammatory diseases in Korea. In this study, we attempted to evaluate the effects of NJ on atopic dermatitis (AD)-like lesions and mast cell-mediated allergy inflammation in vivo and in vitro. Methods and Results We investigated to ascertain the pharmacological effects of NJ on 2,4-dinitrofluorobenzene (DNFB)-induced allergic reactions under in vivo conditions. Additionally, to find possible explanations for the anti-inflammatory mechanisms of NJ, we evaluated the regulatory effects of NJ on the level of inflammatory mediators in phorbol 12-myristate 13-acetate plus calcium ionophore A23187 (PMACI)-stimulated human mast cells (HMC-1). Conclusions NJ inhibited the production of the inflammatory cytokines (IgE, IL-6, IL-8 and TNF-${\alpha}$) significantly in vivo and in vitro.

  • This paper provides the up to date review of the shading effects on PV module performance and the associated detection algorithm related to the maximum power point tracking. It includes the brief explanations of the MMP variations due to the shading occurrence on the PV modules. Review of experimental and simulation studies highlighting the significant impacts of shading on PV efficiencies were presented. The literature indicates that even the partial shading of a single cell can greatly drop the entire module voltage and power efficiency. The MMP tracking approaches were also reviewed in this study. Both conventional and advanced soft computing methods such as ANN, FLC and EA were described for the proper tracking of MMP under shaded conditions. This paper would be the basic source and the comprehensive information associated with the shading effects and relevant MPP tracking technique.

  • The purpose of this study was to examine the effects of culture teaching and using web sites as a method of culture teaching in college English education. To achieve these purposes, a web-based culture teaching-learning model was developed and applied in English classes. Then, the effects were compared with those of a culture teaching method which were based on the traditional verbal explanation. As the tools for this study, two test sheets were used to measure language proficiency and American cultural knowledge. Focusing on the study results, the conclusions were summed up as follows: First, for enhancing the American cultural knowledge, using the web was found to be more effective than traditional verbal explanations. Second, for English language enhancement through web-based culture teaching, it is necessary to do it for each level of English proficiency or develop web sites which fit well with students' interests or levels.

  • The purpose of this study was to investigate whether the experience of computer programming in Logo geometry advances the development of young children's concepts and/or representation of Euclidian spatial relations, particularly their concepts of the vertical-horizontal. Papert's claim of the positive effects of Logo programming experiences on young children's cognitive development was tested using the Piagetian Water Level Test (PWLT), the Free Hand Drawing Test (FHDT), and the Computer Drawing Test (CDT). Forty-four subjects were drawn from 2nd graders attending a public elementary school in Ithaca. The subjects were divided into 2 groups: a treatment group (TG) with Logo training for 10 weeks and a control group (CG) without Logo training. Our results showed that TG did not make any significant improvement on PWLT. In contrast, TG outperformed CG on FHDT. We suggested several possible explanations for this contradiction.

  • The purpose of this paper is to investigate the effects of anti-smoking advertising on attitude toward anti-smoking and behavioral intention to quit smoking in terms of audience's involvement with anti-smoking and knowledge on smoking. For this, a total of 10 hypothesis were established and statistically tested. According to the results, all but hypothesis 1-1(attitude toward anti-smoking is more favorable in the high involvement condition than in the low involvement condition) were unfortunately rejected. These results can be justified by theoretical explanations such as Hierarchy Effects Model or Elaboration Likelihood Model. In addition, some methodological reasons were provided as well.

  • The ketogenic diet has been widely used and proved to be effective for intractable epilepsy. Although the mechanisms underlying its antiepileptic effects remain to be proven, there are increasing experimental evidences for its neuroprotective effects along with many researches about expanding use of the diet in other neurologic disorders. The first success was reported in glucose transporter type 1 deficiency syndrome, in which the diet served as an alternative metabolic source. Many neurologic disorders share some of the common pathologic mechanisms such as mitochondrial dysfunction, altered neurotransmitter function and synaptic transmission, or abnormal regulation of reactive oxygen species, and the role of the ketogenic diet has been postulated in these mechanisms. In this article, we introduce an overview about the expanding use and emerging trials of the ketogenic diet in various neurologic disorders excluding intractable epilepsy and provide explanations of the mechanisms in that usage.
