Future warfare will be conducted by weapons systems using advanced defense technology. Hence, various information generated on the battlefield must be distributed quickly and reliably to operate these sophisticated systems effectively. On the other hand, Korea's current tactical network does not provide sufficient support in many aspects, such as distributing large amounts of information and ensuring communication services during movement. Therefore, tactical networks will require low-latency, high-capacity, and high-speed networks that guarantee uninterrupted connectivity to prepare for future warfare using weapon systems using cutting-edge technology. This paper analyzes the operational concept of future warfare and the communication requirements and considerations necessary for the effective operation of weapon systems to build a tactical network for future warfare. This paper presents future tactical network development plans, such as standardization between communication systems, construction of low-latency and high-capacity networks, support for communication between maneuvers, and securing frequencies.

As for the research contents, topics of articles by year, characteristics by the type of researchers, and methodologies used in the published papers; as for the experimental research, experimental contents were also analyzed. Following are the major findings from the study: First, classifying the 333 articles published in the journal showed that 66.6 papers on average were published in this journal, and the most frequently the profile of the first author was a female professor majored in special education. The most frequent affiliation was Daegu University, the most frequent authorship was co-authorship with two authors and the most frequent method of research was conducting a survey. A further cross-analysis between the first author’s background and methodologies as variants indicated that special education is the most frequent in among case study articles, social welfare is the most frequent among survey research, and papers with the method of correlation analysis was mostly conducted by psychology majors. Mostly case study articles were written by adjunct professors and teachers, comparative research by Ph.D. degree holders, and survey research by MA degree holders. Second, according to the result of analyzing 51 experimental research papers, research subjects were ordinary elementary school students, with an experimental group of 10 or less and a control group of 11 to 20 in most cases. Also, the most common type of experiment design was pretest-posttest control group design. The most common way of complying with the research ethics was getting the agreement of the concerned party. Finally, the period of the experiment were frequently less than two tor three months, with eleven to twenty sessions. The most favored statistical tool was SPSS, and the number of papers that conducted independent sample t-test was most high. However, there were a considerable amount of papers that failed to present social validity nor mediation fidelity. Based on the results mentioned above, this study discusses and suggests a guideline for improving research methodology, in order to enhance the quality of 「Journal of Emotional & Behavioral Disorders」. 본 연구는 ‘한국정서·행동장애아교육학회’에서 발간하는「정서·행동장애연구」학술지에 2012년부터 2016년까지 게재된 333편의 논문들에 대한 연구방법 및 내용을 분석하는 것이다. 연구내용으로는 연도별 게재논문, 연구자의 특성, 게재논문들의 연구방법을 알아보고, 실험연구를 중심으로 내용을 분석하였다. 연구결과를 살펴보면, 첫째, 게재논문 총 333편을 분석한 결과, 연평균 66.6편을 발행하였으며, 제1저자는 특수교육 전공, 대학 교수, 여성이 많았다. 소속대학은 대구대학교, 연구자 수는 2인 공동연구, 연구방법은 조사연구 논문이 가장 많았다. 그리고 제1저자의 배경변인과 연구방법을 교차 분석한 결과, 사례연구는 특수교육학, 조사연구는 사회복지학, 상관연구는 심리학 전공자가 많았으며, 사례연구는 외래교수와 교사, 비교연구는 박사, 조사연구는 석사가 주로 하였다. 둘째, 실험연구 논문 51편을 분석한 결과, 연구대상은 주로 초등학교 일반학생이었으며, 실험집단 수는 10명 이하, 통제집단 수는 11~20명, 실험설계 유형은 사전사후 통제집단 설계, 연구윤리 준수는 당사자 동의, 실험기간은 2~3개월 미만, 실험회기는 11~20회기, 통계도구는 SPSS, 통계방법은 독립표본 t검정을 사용한 연구가 가장 많았다. 하지만 사회적 타당도와 중재충실도를 제시하지 않은 논문이 매우 많았다. 이상의 연구결과를 바탕으로 「정서·행동장애연구」학술지의 질적 향상을 위한 연구방법 개선 방안을 논의 및 제언하였다.

This study examined the effectiveness of video modeled social story interventions for children diagnosed with autism to improve their social interaction. Three of elementary school children with autism, the age of 8 and 10, participated in the study. Using a multiple probe design across subjects, the video modeled social story intervention was implemented to the subject. The dependent measures for each subject consisted of specific target behaviors that occurred in baseline, intervention, maintenance, and generalization contexts. visual analysis, average and standard deviation, inclination, overlapping data were examined. The results of this study showed as follows. The intervention showed effectiveness in increase in the proportion of appropriate social interaction with all the subjects. As the intervention session were advancing, the proportion of appropriate social interaction was rapidly increased while relatively, the proportion of the absence of social interaction was promptly decreased. And in the stage of maintenance after the intervention has been closed, the state remained intact. The increased level of the appropriate social interaction were generalized to different environments. The results of the study suggests that the video modeled social story intervention may have effectiveness to improve appropriate interaction in social contexts for children with autism spectrum disorders. Additionally, the intervention may have effectiveness in managing social interaction for children with autism spectrum disorders.

This study conducted a survey to analyze the condition of integrated child-care and a general recognition of integrated child-care for children with disabilities for the child-care teachers who work in the child-care centers in G province. As the result of study, there are as follows: First, most of the child-care teachers work in general child-care centers where children don’t have disabilities. They rarely participated in the training seminars for integrated child-care. Even if they participated in it, they attended for a short time. Second, most of the child-care teachers agreed that the children with disabilities enter into general child-care centers. They answered that the children with disabilities would be better be placed in a child-care center already integrated with children with disabilities and that the integrated child-care would be of help to the normal children. Third, the child-care teachers answered that to care integrally in all fields of disability is very difficult. Especially, they answered that it is more difficult to care for multiple-handicapped children and autistic spectrum disorder children. Fourth, the child-care teachers answered that as the integrated child-care is positive for all children, it would be better to start early as soon as possible and provide more education on understanding children with disabilities. Fifth, they answered that the child-care centers where they work are badly prepared. Moreover, even child-care teachers don’t have expertise in special education. Sixth, the integrated child-care may have positive effects on promoting social development, offering a chance to understand, to cooperate and to help each other. Also it can help improve the perception of normal children for children with disabilities through interplay between both. Seventh, the negative effects of integrated child-care were that the child-care teachers had to spend more time on children with disabilities, that parents of the normal children had reluctance for integrated child-care and also that there was a possibility to decrease of children in the child-care center. 본 연구는 G도 소재 어린이집 보육교사들을 대상으로 통합보육 현황과 장애영유아 통합보육에 대한 전반적 인식을 분석하고자 설문조사를 실시하였다. 연구 결과, 첫째, 보육교사들은 장애영유아가 없는 일반어린이집에 대부분 근무하고 있었으며, 통합보육 연수에 참여한 적이 거의 없었으며, 참여한 경우에도 참여시간이 매우 적었다. 둘째, 장애영유아의 일반어린이집 입소에 대해 대부분 동의하였으며, 배치장소로는 장애아 통합어린이집이 적절하며, 통합보육은 영유아 모두에게 도움이 될 것이라고 답하였다. 셋째, 보육교사들은 장애종류와 정도에 관계없이 모두 통합보육이 매우 힘들 것이며, 특히 중복장애와 자폐성장애를 더 힘들 것이라고 답하였다. 넷째, 통합보육은 모든 영유아에게 긍정적이므로 가능한 일찍 시작하는 것이 좋으며, 반드시 장애이해교육이 필요하다고 하였다. 다섯째, 현재 근무하고 있는 어린이집은 통합보육 준비가 매우 부족한 상황이며, 보육교사 자신도 특수교육 전문성이 부족하다고 응답하였다. 여섯째, 통합보육의 긍정적 영향으로 영유아 간의 상호작용 확대를 통한 사회성 발달 촉진, 서로 이해하고 협동하고 도와주는 기회 제공, 장애영유아에 대한 일반영유아의 인식 개선 등이었다. 일곱째, 통합보육의 부정적인 영향으로는 보육교사가 장애영유아에게 더 많은 시간을 할애해야 한다는 것, 일반영유아 학부모들의 통합보육에 대한 거부감, 어린이집 재원 원아의 감소 가능성 등이었다.

企業倒産豫測 情報의 有用性 比較硏究

Corporate failure is a very important issue in both the private and social aspects, since the failure obviously causes various adverse effects on national economy such as the increase of unemloyment, resource misallocation and so on. As such, model development for the prediction of corporate failure has been necessitated as its enables both the private company itself and the Government to detect the early symptoms of the probable failure and to take preventive measures, i.e., operating policy changes, financial aids and reorganization of financial structures etc. This study has two major objectives, the one being the construction of high predictive corporate failure model with both accounting and non-accounting information, while the other being the comparison of usefulness of both categories of information in predicting power of corporate failure. Most of the corporate failure prediction model developed so far have generally followed one of two kinds. The first focused on the theoretical approach which attempted to identify and generalize the causes of corporate failure in theoratical context while the second stressed the empirical evidence which intended to find several characteristics of the failed firms relative to unfailed firms. This thesis belongs to the latter one in which the sample consists of 105 failed firms and 124 unfailed firms by paired sample technique. All of the sampled firms, mostly belongs to small and medium industries, borrowed money from banks during 1984 under the gurrantee of Korean Credit Gurrantee Fund. The definition of failure pertains to rather real and than legal one such that any firm experienced insolvency or overdue of the loan was classified as failed firm regardless of whether it was legally declared bankrupt or not. In modeling, this thesis processed both the accounting variables and non-accounting variables seperately and both which multiple discriminant analysis(MDA). This is because I Would like to develope the model as high as possible in predictive power and to compare tht usefulness of two categories of variable simultaneously. The size of usefulness in this comparison is defined as the relative scale of absolute cannonical discriminant coefficient of each variable. The major findings of this thesis follow, 1) Despite the statistical shortcomings of MDA's rigid assumptions such as multivariate normal distribution and equal covariance structure of two groups, it appears that the model developed here using MDA with accounting and non-accounting variables is relatively high in predictive power, This means that the model can be used as on early warning signal of corporate failure. 2) As expected, the empirical evidence should be poorer predictive power of accounting information than that of non-accounting information. This has on intuitive appeal considering the financial statement, dubious in its reliability, especially of small and medium industries of Korea. It means, therefore, that the corporate failure predicting model hereafter should incorporate non-accounting variable into modeling in addition to accounting variables. Finally, the performance the model developed in this study may give some implications to incumbent credit evaluation model of banks in korea which contains about 70% of accounting variables in weights.
