대동작 운동 수행능력 측정도구(GMPM)는 뇌성마비 아동의 움직임을 질적인 면에서 평가하기 위해 개발된 도구이다. 이 연구의 목적은 대동작 운동 수행능력 측정도구의 측정자간 신뢰도를 알아보는 것이다. 뇌성마비 아동 10명(평균 5.6세, 범위 4~8세)에게 GMPM 평가를 실시하였다. 평가 과정을 비디오로 녹화하여 각 속성 항목별로 3명의 평가자간의 급간내 상관계수로 일치도를 보았다. 전반적으로 측정자간 신뢰도는 '불량~보통'범주에 속했다. 이 연구의 결과는 충분한 교육을 받지 않고 평가하면 그 결과를 신뢰하기 어렵다는 것을 말해준다. 향후 임상에서 GMPM을 이용하여 평가할 때 측정자간 신뢰도에 어떤 변화가 있는지 알아보는 연구가 필요하다.

This study carried out an experimental English pronunciation assessment to see the differences in the relationship between the different rater categories. The result shows that i) correlation between Korean and Native American raters is high(r=.98) enough to be considered reliable, ii) previous instructions about assessment rubric and the knowledge about English phonetics and phonology exert little influence on the rating scores, iii) correlation between the automatic ILT(Interactive Language Tutor) rating using speech recognition technology and Natives' rating is stronger than that between ILT and Koreans' rating.

The present study was initiated under the hypotheses that value orientation of wives is closely related to their decision making style in home management and that family life satisfaction of wives varies according to their decision making style. To test the hypotheses the following procedures were undertaken; (1) developing measurement instruments for value orientation, decision making style, and family life satisfaction; (2) finding value orientation of wives, their decision making style, and their family life satisfaction by applying the measurement instruments; (3) finding the variables highly affecting value orientation, decision making style and family life satisfaction ; and (4) finding the causal mechanism among value orientation, decision making style, and family life satisfaction. In conclusion , preferences of wives for humanism in value orientation were expected to lead decision making style to person -oriented rater than task-oriented style and , furthermore, to result in higher family life satisfaction.

EMI (English as a Medium of Instruction) classes are now accepted policy at Korean universities, yet students often struggle with required academic English writings. The present study examined an EMI class that used direct instruction and access to online assistive English writing software. From preliminary analysis, 26 students expressed interest in how an EMI academic writing class could facilitate improved English writing skills. Study participants completed a survey on self-efficacy and learning needs and assignments for an EMI academic writing class. To establish inter-rater reliability, three trained raters assessed the written essays of students prior to and after instructional intervention. Fleiss' Kappas statistics showed moderate reliability. Students' opinions on the use of online software were also analysed. Paired t-test was run on the quality of students' pre- and post-instruction assignments, and there was significant difference in the rated scores. Self-efficacy was found to have moderate positive association with improved post-essay writing scores.

The z-coordinate distribution of cepheids was studied and the finding of Fernie(1968) that the cepheid layer is inclined to ward a formal Galactic plane and the Sun is located above the cepheid plane was confirmed. It was found that the z-distribution fits better to the parabolic form than a barometric form and a scale height of 54 pc was found. The well known phenomenon that the periods of classical cepheids decrease away from the Galactic center was crudely interpreted as due to an age gradient rater than an abundance gradient under the assumption that relations between the period and galactocentric distance, and between the abundance and period are linear.

The purpose of this study is to investigate into the various ways that the computer technology is used for language testing. Three uses of computer technology are mentioned: 1) computer-adaptive language testing and computer-based language testing, 2) the scoring of performance-based language assessment, and 3) the development and use of psychometric tools for analyzing the scoring results. Although the various uses of computer technology could provide expanded possibilities for language testing development, the developers should be reminded that they are currently subject to indepth research which could support their validity. In this regard, the advantages and limitations of some uses of computer technology for language testing are discussed.

This paper analyzes impedance convergence characteristics and harmonics of electric locomotives operation and fault condition. To simulate the various fault and operation condition, AT feeding system and various locomotives are modeled using PSCAD/EMTDC. Analysis shows that impedance are converged into protection area in the case of short fault between catenary and rail or catenary and feeder line but in the case of disconnection fault, impedance is rater bigger so protective relay can't detect the fault. Therefore more analysis of overload and high impedance fault caused disconnection fault is needed.

The Advanced Pressurized rater Reactor 1400(APR1400) system is advanced of the successful Korean Nuclear Power Plants(KSNP) design which meets functional needs for safety enhancement reliability improvement, and control in the human-computer monitoring system. Therefore this paper describes the scoring model in order to justify the reliability and safety in APR 1400 under uncertainty. The structure of this paper consists of the human engineering, risk safety, quality function, safety organization management factors of the qualitative factors in chapter 2, and the expectation results of the normalized scoring model in chapter 3. Finally, the proposed reliability model have provided the technical flexibility not only for functional control fields but also for accidents protection systems in APR 1400 under uncertainty.

Intrinsic gettering is usually to improve wafer quality, which is an important factor for reliable ULSI devices. In order to generate oxygen precipitation in lightly and heavily boron doped silicon wafers with or without high $^75 As^+$ ion implantation, the 2-step annealing method was adopted. After annealing, the were cleaved and etched with th Wright etchant. The morphology of cross section on samples was inspected by FESEM(field emission scanning electron microscopy). The morphology of unimplanted samples was rater rough than that of the implanted. Oxygen precipitation density observed by an optical microscope in lightly boron doped samples was about 3$\times10^6/cm^3$. However, in heavily boron doped samples, the density of oxygen precipitation was largest at $600^{\circ}C$ in 1st annealing, and decreased abruptly until $800^{\circ}C$, But it increased slightly at $1000^{\circ}C$ and was independent with the implantation.
