High-speed rail study needs to focus on passenger movements as a key element of the planning process. A particular challenge is obtaining comprehensive information on high-speed rail passenger movements. A national preference stated survey was conducted from October to November of 2011 to meet this challenge through direct personal interviews of travelers between Seoul and Busan (the so called Kyung-Bu corridor). Over 40 interviewers were hired and trained to conduct personal interviews at several stations along locations within Kyung-Bu Seoul and Busan corridor. A total of 4,550 travelers were interviewed, furnishing an extensive database on high-speed rail passenger movements. The methodology and procedure employed to collect the national data for Korean high-speed train KTX are described. Specific issues investigated include survey design, questionnaire and strategy. Lessons learned from the high-speed rail passenger movement study provide insights for other countries contemplating similar high-speed rail studies.

The purpose of this study was to examine the effects of parenting behavior and peer interaction on externalizing problem behaviors of preschoolers. The data of 953 49~55 month old preschoolers and their parents were extracted from the Korean Children Panel Survey of Child-Care Policy Research Institute(2012). This study was conducted with Structural Equation Modeling(SEM). The results of this study were as follows. First, parenting behavior had a direct influence on externalizing problem behaviors of preschoolers. Second, parenting behavior had a direct influence on preschoolers' peer interaction. Third, preschoolers' peer interaction had a direct influence on externalizing problem behaviors of preschoolers. Fourth, preschoolers' peer interaction had mediating effects on the relationship between parenting behavior and externalizing problem behaviors of preschoolers.

The purpose of this paper is to evaluate optimum rate of payment and to [md the new advanced direction for the program for rural landscape conservation. We used direct evaluation method for income and production costs. According to the survey, we had done from 41 complexes(farmers) joined this program, the average production cost of landscape crops of type1 is calculated at 178,582 won per 10a and 111,517 won as type2. If the classification of crop type is adjusted, the problem formulated is improved to make possible support at the current payment rate.

The purpose of this study was to analyze the structural relationships between adult educators' instructional leadership, learners' motivation and performance among those participants in education for urban-rural migration. The survey was conducted among 22 agricultural educational institutions in South Korea, and a total number of 1,109 learners responded to a questionnaire. In order to verify the hypothesized research model, the collected data were analyzed with structural equation modeling. The major findings of this study were as follows. First, adult educators' instructional leadership had a direct effect and an indirect effect on learners' performance. Second, adult educators' instructional leadership had a direct effect on learners' motivation. Third, learners' motivation had a direct effect on learners' performance.

It is well known that ISO 9001 and TQM have significant effects on business success. We analyzed the effects of ISO 9001 requirements and TQM on financial performance with structural equation modeling. Hypotheses are proposed and tested based on existing beliefs, proposition and prior research concerning quality. Survey data were collected from 291 manufacturing companies with ISO 9001 certifications. The data show that ISO 9001:2008 requirements have significant positive direct effects on TQM practices, but do not have positive direct effects on financial performance. As expected, TQM has significant positive direct effects on financial performance. One of the important results is that efforts to meet ISO 9001:2008 requirements enhance TQM practices which, in turn, helps to improve financial performance. Findings in this study support the claims that ISO 9001:2008 would be a good step toward total quality management and is a meaningful component of TQM.

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.

In order to discover the candidates of emission-line galaxies towards Hydra Void, objective-prism observations using U.K. Schmidt Telescope were carried out. To search the emission feature of [0III]${\lambda}{\lambda}4959,5007$ for all objects on the plate, all observed prism plates were scanned with APM at the Royal Observatory and the copied direct R plates were scanned with PDS Microdensitometer operating in the Inter- University Center for National Science Research Facilities. By utilizing the "XIMTOOL" package, both spectral and direct images for the same field were displayed simultaneously on up and down windows separately. In case of distinct emission features for a certain object, corresponding direct object on the other window was examined through eyeballing to see whether this object is a galaxy. Through this procedure, we discovered in total 33 candidates of emission-line galaxies in a single field.

This paper discusses several low-temperature heat-tranfer fluids, including water-based inorganic salt, organic salt, alcohol/glycol mixtures, silicones, and halogenated hydrocarbons in order to choose the best heat-transfer fluid for the newly designed direct contact refrigeration system. So, it contains a survey on commercial products such as propylene glycol and potassium formate as newly used in super market and food processing refrigeration. The stability of commercial fluids at the working temperature of $-20^{\circ}C$ was monitored as a function of time up to two months. And organic and inorganic compositions of candidate fluids were obtained by analytical instruments such as ES, XRF, AAS, ICP-AES, GC, and GC-MS. Analysis results indicate that commercial propylene glycol is very efficient and safe heat transfer fluids for the direct cooling system with liquid phase.

수변 콘크리트 구조물의 누수 탐지를 위해 변형된 배열을 이용하여 전기비저항 탐사를 실시하였다. 전극을 수면에 설치하여 콘크리트 구조물에 대한 새로운 전기비저항 탐사 방식을 제안하였으며, 해석의 단순화를 위해 선형 전류 송신원을 전류전극으로 사용하였다. 마지막으로 전위차를 얻는 방법에 따라 변형된 3가지 전극 배열을 제안하였고, 동일열전위 배열(direct potential array), 평행열 전위 배열(parallel potential array), 횡단 전위 배열(cross potential array)로 명명하였다. 변형된 전기비저항 탐사법을 수치해석, 실내 모형실험, 현장탐사에 적용한 후 그 결과를 비교 분석하여 수변 콘크리트 구조물의 누수 탐지 기술로서의 적합성을 알아보았다. 비교 분석 결과 동일열 전위 배열, 평행열 전위 배열, 횡단전위 배열 모두 누수가 일어날 때, 누수지점에서 뚜렷한 전위차의 변화 양상을 보여 수변 콘크리트 구조물의 누수 탐지에 유용한 방법임을 확인하였다.
