Dispite the fact that our military has outwardly made notable accomplishments such as the development of weapon systems like tanks, self-propelled artillery, and missiles, there has been a lack of attention to producing weapon effectiveness data that suggests a standard as to what effects the developed weapons will demonstrate on the battlefield. For such reasons, most of the weapon effectiveness data utilizes JMEM data introduced by the United States and as for the rest of the data that cannot be acquired, respective branches create and utilize their own data through research. This research aims to develop a reliable methodology that can meet the requirements of the requesting branches in a short span of time and at a low cost by studying the existing weapon effectiveness data production methodologies such as that of JMEM. As a result I have developed a method that calculates the vulnerable area and the probability of kill of the weapon system that one wants to calculate by applying statistical technique and simulation technique based on weapon effectiveness data of similar weapon systems in JMEM and live test data. 우리 군이 그동안 전차, 자주포, 미사일 등 주요 무기체계를 개발하여 전력화 하면서 외형적으로 괄목할만한 성과를 이루어 왔음에도 불구하고, 개발된 무기가 실제 전장에서 어떤 효과를 발휘할 것인가에 대한 척도를 제시해 주는 무기효과자료를 산출하는 것에 대해서는 관심이 부족하였다. 이러한 이유로 아직까지 무기효과자료 산출을 위한 기반이 미흡하여, 무기효과자료는 대부분 미국으로부터 도입된 JMEM 자료를 활용하고 있고 미 확보된 자료에 대해서는 사용부서에서 각자 연구하여 데이터를 생산, 활용하고 있다. 따라서 본 연구에서는 기존에 수행되어 온 무기효과 산출방법론을 연구하여 간편하면서도 적은 예산으로 신뢰성있는 무기효과자료를 산출할 수 있는 방법을 도출하는 데 중점을 두었다. 미국의 JMEM 방법론으로부터 식별한 절차 및 알고리즘을 활용하고, 현재 한국군이 보유하고 있는 유사 무기체계의 무기효과자료를 기초로 통계 및 시뮬레이션기법을 복합적으로 적용하여 직사화기 중 대표화기인 전차를 중심으로 살상확률(Pk)을 계산하는 방법론을 제시하였다.

This study was carried out to present the informations for the optimum age of selection based on partial records to improve egg weight in layers. The data used in this study were the records on 787 White Leghorn hens from two different strains, A and K, which were raised at College of Agriculture, Seoul National University since 1976. The traits analysed in this study were mean egg weights in each period divided into 4 week intervals from first egg and annual mean egg weight in lines A and K. Heritability estimates for mean egg weight in each period from sire component and dam component were; different in appearance in two lines. In line A, the fact that heritability estimates from sire component was higher than those from dam component except for EW 22 suggested the importance of the sex-linkage effect on the inheritance of the traits studied. But the result of line K was shown to be reverse. The heritability estimate for EW 30 that is mean egg weight from 29 weeks to 32 weeks of age was higher than any other periods in line A. In the genetic correlation between. annual mean egg weight and mean egg weights in each period, the coefficient of EW 34 was 0.999 for line A and 0.900 for line K. The figures were highest among all genetic correlation coefficients. Results obtained above suggested that it might be possible to select hens at the period of 33-36 weeks of age to improve egg weight based on early part of the record.

This study was carried out to develop the computer software system for the layer farm management by using microcomputer (IBM-P/C compatible). Pull-down system was adopted to develop the software system (LAMASystem Layer Management System) by using menu-driven method for the end-user lacked experience of` computer system. COBOL. and CLIPPER were selected as computer languages to develop the LAMASystem. The LAMASystem had primary menus which were ENTRY, DATA-INPUC, PLAN-OUTPUT, REPORT-OUTPUT, ANALYSIS-OUTPUT and each primary menu consisted of 31 kind sub-menus through hierarchical structure. Increasing the layer farm productivity was expected by applying the LAMASystem through systematic data collection and handling.

본 연구는 정신지체 특수학교에서 바우처를 활용한 치료지원을 실시함에 있어서 치료지원 영역 결정 과정과 그 결과 활용 및 개선방안에 대한 특수교사들의 의견을 조사, 분석하여 개선방안을 제시하는 것을 목적으로 하였다. 이를 위해 서울시 정신지체 특수학교 10곳에 근무하는 40명의 특수교사들을 대상으로 설문 조사를 실하였다. 이 연구의 주요 결과는 다음과 같다. 첫째, 치료지원 영역 결정 과정과 관련하여 가장 큰 영향을 주는 주체는 부모이며, 학생의 장애특성, 치료기관까지의 이동거리 및 위치, 이동방법이 영향을 미치는 요소인 것으로 나타났다. 치료지원과 관련된 협의회는 년 1회 미만이 많았으며, 주로 서면이나 알림장을 이용했다. 학생에게 적합한 치료지원 영역을 결정하기 위해 개별화교육지원팀 회의가 필요하다는 의견이 많았고, 현재 개별화교육지원팀 회의가 잘 이루어지지 않은 이유로는 관련전문가가 한자리에 참석하기 어렵기 때문인 것으로 나타났다. 둘째, 치료지원 결과 활용과 관련하여 대부분의 교사들은 치료지원 제공 기록지를 수령하고 있지만 기록지의 내용이 빈약해서 교육활동에 반영하기에는 충분치 않다는 응답이 많았다. 셋째, 치료지원 운영 개선과 관련해서 치료지원 인력과의 의사소통 기회 확보, 부모의 치료지원 인력에 대한 상세한 치료지원 결과 요구, 치료지원 전담 코디네이터의 필요성 등의 방안이 제시되었다. 위의 결과를 종합하여 향후 치료지원 개선방안을 제시했으며, 이는 치료지원 관련 정책을 수정·보완해 나가는데 도움이 될 것으로 기대된다. The purpose of this study is to investigate the practices and opinions about voucher based therapeutic supports of teachers in special schools for students with mental retardation. For this purpose, 40 teachers who work in 10 special schools in Seoul participated in this survey and its main results were the following:First, in connection with the determination process of voucher based therapeutic support area, the most influential person was the parents of students, and influential factors were disability type, moving distance to service institution, the location of the institution, and moving method. Opinions of the teachers about meetings for therapeutic support were also collected and analysed. Second, in connection with the results of voucher based therapeutic support, it is revealed that the teachers take the therapeutic support records from the institutions well, but their contents were not specific enough to use them for educational purposes in school. Third, for improvement of therapeutic support system, communication with therapists, participation of the parents, the needs of therapeutic support coordinator, etc. were explored. For better operations of the voucher based therapeutic supports, the authors proposed several suggestions.

Purpose: The purpose of this study is to explore the role of national representative coach leadership in facilitating the positive development of athletes in Taekwondo. Method: This study develops a theoretical model from expert panel meetings; two former national coaches, two former national athletes, and a professor with a major in Taekwondo. Based on the panel meetings, the Analytic Hierarchy Process (AHP) was employed to investigate the evaluation model. Specifically, we used an online AHP tool provided by BPMSG AHP Online System. Results: The results of the study are as follows. The upper items were higher in the order of the communication ability (0.403), expertise (0.384), leader literacy (0.150), and administration (0.063), while the lower items were higher in the order of physical training (0.285), technique analysis (0.257), performance analysis (0.242), and program diversity (0.216). The priority of the communication abilities were higher in the order of physical conditioning (0.399), trust and understanding (0.394), and athlete characteristics (0.207), leader literacy in the order of sense of mission (0.469), teaching philosophy (0.299), and reflective attitude (0.232), and administration in the order of operation (0.444), foreign relation (0.341), and office management (0.215). Lastly, the composite weights considering all upper and lower items were higher in the order of physical conditioning (0.1607), trust and understanding (0.1587), physical training (0.1094), technique analysis (0.0986), performance analysis (0.0929), program diversity (0.0829), athlete characteristics (0.0834), sense of mission (0.0703), teaching philosophy (0.0448), reflective attitude (0.0348), operation (0.0279), foreign relation (0.0214), and office management (0.0135). Conclusion: In conclusion, this study contributes to a meaningful classification of national coaches’ leadership associated with athlete performance and commitment. In particular, it is important to create an environment where leaders can build trustful relationships with athletes.
