This study investigated differences in beliefs about English learning of 286 EFL college students and 52 English teachers in Korea. Data was collected using Horwitz's Beliefs About Language Learning Inventory and compared between students and teachers in beliefs. To address the research questions, the data were analyzed through descriptive statistics including frequencies, factor analysis, MANOVA, ANOVA, t-test, and reliability coefficients. The results showed four factors in student beliefs: Difficulty of learning English, nature of learning English, importance of correctness in learning English, and motivation and perceived importance of learning English. Clear differences were found in students and teachers' beliefs in English learning aptitude and importance of translation, error correction, and grammar rules. A few belief differences were also identified between Koreans and native-speaking English teachers related to the importance of vocabulary learning, pronunciation, and cultural knowledge. The findings of the study indicated that background variables such as gender and major field of study have an effect on student beliefs about L2 learning. The present study also provided pedagogical considerations to reduce mismatch between students and teachers beliefs and to improve the L2 planning and instruction.

This paper reviews and examines the empirical results of past research concerning individual differences and similarities in landscape preference and evaluation. The conflicting results (differences and similarities) found in the review are attributed to the variety of methodology adopted by the past research and to the lack of comprehensive theoretical base in the field of landscape research. Two suggestions are derived from the review. First, both the landscape type to be evaluated and the measurement context to be used by research subjects have critical importance in results. Thus, it is suggested that researchers should be careful in selecting landscape type and measurement tool. Second, more scholartic endeavours should be put into a development of comprehensive theory of landscape experience that could explain both differences and similarities in people's landscape preference and evaluation. Once developed, the theory would not only provide us more valid and specific research methodology, but also allow us to design more healthy and valued landscape.

This research studied occupational view and perceptions of career education for elementary school by elementary school teachers and parents. Questionnaires were administered to 113 teachers and 523 parents. Data were analyzed by ${\chi}^2$ and t-test. Results showed statistically significant differences in teachers' occupational view by sex, educational background, field experience in elementary school, and experience of inservice teacher education; statistically significant differences in parents' occupational view by sex and age; statistically significant differences between teachers and parents in occupational views; and statistically significant differences between teachers and parents in perceptions of career education. Occupations providing stable livelihood were preferred by parents, by male teachers, teachers with masters' degrees, and by teachers whose education had included inservice training.

The purpose of the study is to examine culinary students' perception of the quality of an OJT(on the job training) program and to investigate their satisfaction levels clustered by the differences in it. Through the survey, the data were obtained from 348 culinary students who had experiences of an OJT program. They were analyzed by SPSS 13.0 and divided into four groups based on the differences of perception. As a result, this study showed that the more the students had a positive perception of OJT program, the more they were satisfied with the program. Therefore, this study will be of great use to seek for alternatives for the promotion of OJT program in the future.

The purpose of this paper is to minimize differences between landscape detailed design (hereafter 'design') and final landscape construction products in working sites (hereafter 'products'). Ten landscape sites constructed in recent two years were selected to examine the differences. Differences in quantities and quality between design and products were surveyed and the results were analyzed with the 'differential analysis method'. The method employed in this paper can be used as an optimization model to minimize the differences between design and products. This paper suggests that every landscape field should mark less than 13.672% calculated from the 10% of total amount for excellent construction products. This should be approved by the president, according to the Clause 20 of General Conditions of the Contract, divided by the ratio of quantities affecting mainly he average Difference in Value between Design and Construction(DVDC). This value can be the critical point from the differential analysis method for the optimal maximum DVDC between landscape design and final landscape construction products in fields.

This study was focused on analyse Nonpoint source characteristics from Flat slope field and Steep slope field. We performed Storm-water monitering for obtain flow data and concentration data. Totally, eleven times Event was occurred. We calculated EMC(Event Mean Concentration) and Pollutants Loads using data we obtained. As a result, steep slope field has more discharge than flat field. SS value, one of the water quality contents, has largest variation and T-N has least variation. There is runoff differences even though events has same rainfall. We assume that not only amount of Rainfall, but also Rainfall Duration Times, Intensity, Number of Previous Non-precipitation days can affect to Run-off.

There are many difficulties to get the scattered field generated by obstacle which has arbitrary shape or irregular surface impedance by using analytic solution or numerical methods. In this study, we propose experimental method of acoustic scattering holography that can predict the far-field scattered field based on nearfield measurements. First of all, we express scattered field using K-H integral equation and compare the differences of which green's function we use. Also we consider analytic solution of scattered field by infinite cylinder to analysis for the errors due to apply cylinderical holography. So the errors which caused by holography due to frequency (ka) and microphone spacing are also analyzed by numerical simulation.

Finite element analysis showed that strong magnetic fields were distributed around the arc furnace where the strongest magnetic fields were generated around the three phase cables. The second and third strongest fields near the arc furnace were found to be generated around the electrodes and the mast-arms, respectively. The generated field intensities were greatly influenced by the mast arm structure of the arc furnace as well as the phase differences and operation currents of the supplied power, Magnetic field decay patterns around the arc furnace could be smoothly fitted by this equation of exponential formula, H=H$0_$+Ae$^{\frac{r}{t}}$. These results revealed that magnetic field intensities around the arc furnace could be estimated at any 3-dimensional position using finite element method (FEM).

This study aims to develop three types of the visual fields: stationary field, eye field, and head field, which are classified depending upon the eye and head movements. A visual experiment taking target size, target color, and meridian into account was conducted, in which the L32 orthogonal array was employed. The results showed that target size and meridian were significant at ${\alpha}$=0.01 in all three visual fields. Contrary to expectation, target color was significant at ${\alpha}$=0.10 only in the head field. Furthermore, the differences in size of the head field depending upon four target colors were negligibly small. Three linear regression models were provided to generate visual fields which are appropriate for given visual task's characteristics. In addition, a simple method using adjusting factor was also proposed so that anyone without knowledge for human factors/ergonomics can easily generate and use them when designing or evaluating visual tasks. It is expected that the visual fields presented in this study can be easily used even by non-ergonomic experts in real situations due to their simplicity.
