김용대 ( Yong Dae Kim ),최길수 ( Gil Su Choi ),이종연 ( Jong Yun Lee ) 한국컴퓨터교육학회 2012 컴퓨터교육학회 논문지 Vol.15 No.1

정보 교과는 지식정보화 사회에 필요한 정보 활용 능력은 물론 창의적인 문제해결력을 함양하기 개설된 교과이다. 그러나 창의적 문제해결요소가 교과서에 어느 정도 포함되었는지를 분석하는 연구는 미미하다. 따라서 본 논문은 중학교 정보 1 교과서 ``문제해결방법 및 절차`` 영역의 창의적 문제해결력 경향을 정량적으로 분석하였다. 정보 교과서가 창의적 문제해결력 함양 요소를 어느 정도 포함하고 있는지 최길수의 정량적 분석법으로 분석한 결과, 교과서별로 문제해결과정 반영과 문제해결전략 제시의 충실도에 차이가 크게 나타났고 모든 교과서가 활동 요구 지수, 창의적 문제해결력 관련지수, 활동 유형지수가 전체적으로는 바람직한 범위에 있으나 소 영역별로는 바람직한 범위를 벗어난 것이 있는 것으로 나타났으며 지수 값이 균형을 이루지 못한 교과서가 있고 활동 유형이 일부 유형에 치우쳐 있는 것으로 나타났다. 그러므로 앞으로 정보 교과서의 개발 및 수정 보완 시 문제해결과정 반영과 문제해결전략의 충실도를 높이고, 교과서의 학습 활동 구성 시 다양한 학습 활동 유형을 활용하고 기본 정신 기능과 고등 정신 기능을 요구하는 활동 비율의 균형을 유지할 것을 제안하였다. Developing middle and high students` information literacy and creative problem-solving skills in this information-oriented society is very important and for this reason, the subject of informatics has been established. However, little research on creative problem solving literacy of informatics textbooks has been conducted. Therefore, the purpose of this paper is to quantitatively analyze whether ``problem-solving methods and procedures`` parts in informatics textbooks in middle schools present creative problem solving literacy or not and in what degree. Data were quantitatively analyzed using the Gil-Su Choi method. The result of data analysis indicated that all the textbooks turned out to be correct range in the category of the "composition of various learning activities," but got out of range in some categories such as "problem-solving process reflection` and "problem-solving strategy proposal". Also a few textbooks haven`t satisfied in important indexes and activities. So, we suggest that more ``problem-solving process reflection`` and ``problem-solving strategy proposal`` parts should be included in the informatics textbook and more various forms of learning activities be utilized well as the ratio of activities needed primary and high mental processes be kept the balance.

The purposes of this study were to analyze the temperament characteristics of Taekwondo players and to give a good advise in relation to game performance and management of athleths and team administration for Taekwondo instructors. Subjects of this study were randomly selected. The sample consisted of 200 male and female high school and collegiate Taewkondo players. The temperament characteristics were assessed by means of a questionnair developed by Igen(1983). The questionnair which consisted of 59 questions include 3 sub-factors such as sincerity(24),introvert and extrovert(24), and neurosis(9). The results of this study showed that there was significant difference(p<0.01) for neurosis between male high school(14.48) and male collegiate(12.14) Taekwondo players. However, no significant difference could be oberved for all temperament characteristics between male and female high school Taekwondo players, between male and female collegiate Taekwondo players. This study suggests that male Taekwondo players were less for neurosis than female Taekwondo players

Thin films of vanadium oxide(VO_(x)) have been deposited by r.f. magnetron sputtering from V_(2)O_(5) target in gas mixture of argon and oxygen. The oxygen/(oxygen+argon) partial pressure ratio is changed from 0% to 8%. Crystal structure, chemical composition and electrical properties of films sputter-deposited under different oxygen gas pressures have been characterized through XRD, AES, RBS and electrical conductivity measurements. All the films prepared below 8% O_(2) are amorphous, and those prepared without oxygen are gray indicating the presence of V_(2)O_(4) phase in the films. In order to measure the current-voltage characteristics and temperature dependence of conductance, devices of A1/VO_(x)/A1 sandwich structure have been fabricated. I-V characteristics are distinguished between linear and nonlinear region. In the low field region the conduction is due to Schottky emission, while at high field it changes to Fowler-Nordheim tunneling type conduction. The conductivity measurements have shown an Arrhenius dependence of the conductivity on the temperature.

Using conventional textile techniques such as weaving, braiding, knitting and stitching it is possible to produce a wide range two and three dimensional fiber preforms. However, so far only a limited attention has been given to knitted fabrics in composite industry. This is mainly due to the opinion that knitted fabric reinforced composites posses low mechanical properties owing to their looped fiber architecture. But it is possible to obtain desired mechanical properties by selecting proper knitted fabric structure. In this paper, tensile failure load and displacement of one yarn, four yarns and knitted fabrics of ten yarns of kevlar fiber were determined experimentally in the unidirection. Mechanical properties of plain weft knitted fabrics reinforced composite intrusion beam for car side door application were investigated experimentally, which compared with desire value of American Fedral Motor vehicles Safety Standard (FMVSS) and presented the results.

이용학,이호준,최길용,장재신 인제대학교 2012 仁濟論叢 Vol.27 No.1

ARQ schemes are commonly used in various communication areas, for instance TCP protocol, to combat communication packet errors and there are three different types of ARQ protocol. In this paper, the performance of stop-and-wait ARQ scheme is evaluated with computer simulation and then compared with analytical results. Two different traffic generation modes are considered: the first one is the saturated traffic model and the other one is periodic arrival model based on exponential distribution. For performance measures, link utilization and average packet delay are used in this paper. According to numerical results, it is known that performance results from computer simulations coincide well with those by mathematical analysis. For the further study, we will continue to carry performance evaluations of two other ARQ schemes, go-back-N ARQ and selective repeat ARQ schemes.

"Biomaterials" are nonviable materials used in medical devices, intended to interact with biological systems. They should have "biocompativility", which is defined as the ability of materials to perform with an appropriate host response in a specific application. It includes many materials that are often classified as biomaterials. Metals, ceramics, polymers, glasses, carbons, and composite materials are some examples. Among them, biodegradable polymers are discussed in this revies article. Since a biodegradable polymeric implant does not have to be removed surgically once it is no longer needed, biodegradable polymers are of value in short-term applications that require only the temporary presence of a polymeric implant. Main short-term medical applications of biodegradable polymers include the temporary tissue scaffold, the temporary adhesion barrier, the drug delivery device, and the multifunctional implant. In this article, the properties, processing methods, and medical applications of the biodegradable polymers are reviewed.
