本稿는 統計學의 理論 개척과 발전을 위해서 應用分野의 연구에 주력해야 할 필요성을 밝히려 한다. 우선 기존의 統計理論이 應用分野에서 生成 발전된 점을 밝히는 동시에 應用分野에 대한 연구의 관심을 확대시켜야 할 필요성을 설명하려 한다. 물론 數理統計學이나 確率論과 같은 分野는 論理的 硏究方法으로 數理解析의 발전이나 方法을 개척할 수가 있다. 그러나 그것도 人類의 福祉증진에 기여하게 된다는 최종적인 목적성이 전제된다면 현실의 應用分野와 결코 무관할 수는 없을 것이다. 이상과 같은 목적을 위해서 우선 統計學이 과학으로 성립하기 이전의 生成 배경을 설명하면서 統計學이 人間의 生活과 얼마나 밀접하고 그 대상이 얼마나 광범위한가에 대하여 설명하려 한다. 처음부터 그것은 個人生活보다는 集團生活과 더욱 밀접한 관계가 있었다는 점을 강조하게 된다. 그리고 20世紀初에 론돈大學의 生物測定硏究室, 겔톤優生學硏究室 등을 중심으로 한 웰든, 겔톤, 피어슨 그리고 네이만의 生物測定硏究와 數理統計學연구와 핏샤와 끄ㅅ 등의 연구업적에 의해서 統計學이 科學으로 성립된 歷史的 사실을 반취하면서 統計學의 연구방법과 대상을 간접적으로 인식하게 된다. 또 統計學이 他科學과 비교하여 硏究對象 方法 그리고 實踐的 側面에서의 學問的 特殊性을 설명하면서 統計學연구의 應用側面을 강조하게 된다. 끝으로 선구자들의 統計學연구방법과 태도를 조감하면서 어떻게 하면 새로운 統計的方法을 개척할 수 있고 또 他分理 연구에 기존의 統計的方法이 기여할 수 있는가의 方法을 탐색하게 될 것이다. 즉 專門硏究機關에서, 實務現場에서 새로운 硏究對象을 찾아 새 方法을 개척할 수 있는가 하는 문제를 論議하게 된다. 이러한 탐구는 모두 과거에 統計學발전에 기여한 여러 선구자들의 연구방법과 업적을 되새기면서 유도된다.격)개발에 관심을 가진 사람들이 모이는 일일 것이다. 통계분야에서도 몇가지 표준화 활동이 ISO 를 중심으로 진행되고 있다. 예를 들면 실험과 검증 결과의 표현과 해석, 표본추출 방법 등에 관한 것으로 이들은 통계의 응용분야에서 꼭 필요한 표준이다. 구체적인 예로서 우리나라 국민의 표준체위값을 설정하기 위하여 측정조사할 때 측정방법 뿐 아니라 표본추출 방법과 통계자료 처리과정의 표준화가 이루어 지지 않는다면 각 기관에서 조사 발표하는 체위관계 자료가 상이하여 국가기관의 통계자료에 대한 신뢰성이 저하되고 통계값을 이용하여 의류, 신발 등의 제품을 제조하는 산업계에 혼란을 야기시킬 수 있다. 본 고에서는 ISO의 활동을 정보처리 분야에 초점을 맞춰 간략하게 설명하고 통계분야의 국제 활동을 비전문가인 필자들이 아는대로 소개하는 한편 국내활동의 필요성을 강조하여 관련 기관, 학계 및 산업계 관련전문가들의 ISO 국내활동 참여를 제의하고자 한다.mes$E조합에서는 견층비율의 자잠에서, D$\times$F조합에서는 웅잠의 견층비율에서 비교적 높은 값을 나타내었다.

The purposes of the study was to investigate BYOD (Bring Your Own Device) policy since it would be limited to distribute all of the digital devices required for the schools within the budget of the government. First, the concept and characteristics of BYOD were introduced. Then, the pros and cons of BYOD were analyzed according to the case studies of BYOD policies of the U.S. Based on the previous experiences, guidelines of domestic BYOD policies were established. Regarding the institutional aspect, technical issues, usage, damages, digital divide, information security, and resources were discussed. Additionally, conditions of technology, networks, filtering, software were also considered as essential infrastructure. In sum, as an alternative of distributing digital devices in schools, the importance of BYOD should be regarded as top priorities with systematic preparations in launching digital education. It would be expected that this study play a fundamental role in launching domestic BYOD policy by supporting specific strategies.

In modern cosmology, it is controversial whether the existence of human consciousness can be used as evidence to support the hypothesis that many parallel universes are actualized. In this paper, we want to explore the nature of self-consciousness information that I am awake now. Consider the following experiment participating Al and Bob. We throw a fair coin on Sunday. If the coin lands heads we wake up just one of Al and Bob on Monday. If the coin lands tails we wake up both of Al and Bob. On Monday, at least one of Al and Bob will wake up, to what degree ought they believe that the outcome of the coin toss is heads? We will argue that the correct answer to this question is 1/3. To this end, we will argue the awakened person's information that "I am awake" is given to himself through a random procedure.

The essence of adapting education to the information age consists of two parts. One is the building of infrastructure for information education and the other is putting information and communication technology to educational use. Moreover, from a usage point of view, it is the most important thing that secures much educational software of good quality supporting adapting schools to the information age. It does mean the investigation about the plan of evaluation of educational software is important. Thus, in this study, we provide scientific information for efficient selection and use of educational software as end-users, and provide objective evaluation criteria of quality as a developer. In addition, through this research, we can lay the foundation for adapting education to the information age. For this purpose, we analyzed previous research relevant to the evaluation of educational software, divided the criteria of evaluation into three parts, educational, applicational, and technical, and develop the criteria of evaluation in detail.

Design of a new information technology curriculum is very difficult work. It has relatively short history of operation. It advances very fast. Furthermore, people have very different understandings between information application and information knowledge. Therefore making decision for information technology contents is very difficult work. So we try to get effectiveness of the curriculum design through the comparison with other countries' cases. In this paper we tried to search and analyze about the historical trends, current states, and characteristics of Chinese information technology curriculum. China has strong focus on information technology education while she makes great success in economic development. We also suggested some good points of Chinese information technology curriculum which can be adapted to the design of a new Korean computer curriculum. The China's information technology curriculum is summarized by four categories. They are (1) educations on the basic knowledges and functions of the stable level of information technology, (2) educations on the information technology applications for the problem solving, (3) educations for the individualized learning through the research and project implementations in depth, and (4) systematic arrangements and integrated operations of the information technology curriculum.

In this paper, we investigate a problem with Web-based learing contents and introduce the solving method of the problem. To be more accurate, existing Web-based learning contents were one fixd and uniformed courseware file with a large size and HTML format. Also, They were written files with authoring tools of which depended upon providing a multimedia vender. These learning contents were difficult to reuse among cyber education systems and change the applicable contents to the learner for learning experiences in time. So in this paper, we produced reusable and interopreable learning contents among instruction designers and education systems. They were deconstructed into smaller chunks and added to its properties. For the purpose of this producing method, we used the pedagogical designs for units of reuse. These are just turorial link-more and tell-more and was implemented with CBD method. As a result, The problem of existing Web-based learning contents system was resolved and then the power of understanding about objectified learning content was increased for the learner and instruction designers.

Intuitive learning method was applied at the beginning of each lecture to induce students to draw their interests. Avoiding simple explanation of equations and problem solving by using them, we repeated theoretical concepts verbally and applied physical meanings when we developed and wrote equations. By these methods we expected to find a way to increase students' learning effects. We also took a group investigation on pursuing term projects. Students choose their own subjects individually and submitted reports according to the time schedule. The reports included the contents that they learned during classes. After choosing best reports for each group by instructor, students at each group divided roles and prepared presentations. Thorough these methods they increased their scores from mid-term to final exams, and got aquatinted with responsibilities among group and organizations. They also experienced physical meanings from the usual daily life phenomena which could be connected to the engineering concepts and improved abilities as junior engineers.

In recent years, parents of students and government have been taking a growing interest in education for the gifted students and there are many research reports about the gifted education. Most of the reports, however, focuses on the conceptional feature of the gifted education program such as organization, operation, management, evaluation, etc,. In other words, there are very few researches on instructional materials for gifted students even though the materials is a critical factor for successful education programs. So, this paper introduces a lecture notes used in a personal education for gifted students to contribute in developing education contents in computer science area. The instructional materials titled as "The Necessity and Application of Matrix in Computer Science" is based on linear equation to usher the students into creative problem recognition and groping for solutions. Also, the instructional materials is useful for students to understand the tight mathematics-computer science relationship and the basic concept of liner algebra.

Since the start of gifted education in 2002, educational support system has now been established, and sufficient growth in quantitative aspects has been achieved in Korea. On the other hand, they report that there are insufficient points in terms of education quality. In other words, most of the gifted education simply expands knowledge by prior-learning. In order to improve the quality of gifted education, they should enhance critical-thinking and creativity able to apply interdisciplinary principles or phenomena for solving problems. In this study, we designed and developed a convergent teaching-learning materials based on the concept of integrated education, which explore the process that basic logic operations such as AND, OR, XOR do the role of computer cells. A survey result showed that student satisfaction(usefulness, understanding, interest) of the materials is significantly higher than that of other traditional learning topics, and the design intent was met.

J. Bernoulli first discovered the method which one can produce those formulae for the sum $S_n(k)=\sum_{{\iota}=1}^n\;{\iota}^k$ for any natural numbers k. After then, there has been increasing interest in Bernoulli and Euler numbers associated with Riemann zeta functions. Recently, Kim have been studied extended q-Bernoulli numbers and q-Euler numbers associated with p-adic q-integral on $\mathbb{Z}_p$, and sums of powers of consecutive q-integers, etc. In this paper, we investigate for the historical background and evolution process of the sums of powers of consecutive q-integers and discuss for Euler zeta functions subjects which are studying related to these areas in the recent.
