  • A conceptual model represents an understanding of a system that is going to be developed, which in this research, a driving simulation software to study driver behavior at signalised intersections. Therefore, video observation was conducted to study driver compliance behaviour within the dilemma zone at signalised intersection, with regards to driver's distance from the stop line during yellow light interval. The video was analysed using Thematic Analysis and the data extracted from it was analysed using Chi-Square Independent Test. The Thematic Analysis revealed two major themes which were traffic situation and driver compliance behaviour. Traffic situation is defined as traffic surrounding the driver, such as no car in front and behind, car in front, and car behind. Meanwhile, the Chi-Square Test result indicates that within the dilemma zone, there was a significant relationship between driver compliance behaviour and driver's distance from the stop line during yellow light interval. The closer the drivers were to the stop line, the more likely they were going to comply. In contrast, drivers showed higher non-compliant behavior when further away from stop line. This finding could help in the development of conceptual model of driving simulation with purpose in studying driver behavior.

  • The study investigates the influences of different factors on revisit intention to Korea of Vietnamese tourists. A mixed-method including qualitative and quantitative methodologies were utilized. A focus group of 9 experts was carried out for reviewing and exploring different factors and the conceptual model. An in-depth interview with 19 participants was developed with an aim to develop and correct measurement items. The conceptual model was tested and developed using data collected by a questionnaire, from a sample of 473 respondents, who have visited Korea by both electronic and paper surveys with non-probability and convenience sampling techniques. The questionnaire in this research applied a 5-point Likert scale and was distributed both electronically using Google form and by questionnaire paper. The Bootstrap model was used for estimating the model parameters for retesting the reliability of the estimates. Factor analysis and Structural Equation Modelling are employed to analyze the data. Results showed that 427 tourists traveling by groups organized by travel companies and 46 tourists traveling on their own. The reliability, tangibility, empathy, and assurance had influences on tourists' intention to revisit a destination, especially through satisfaction mediating construct. Destination image, self-congruity, and the emergence of Hallyu had influences intension revisit through attitude and tourist motivation.

  • 최근 이상기후로 집중호우 및 태풍 등과 같은 극한홍수사상의 발생으로 인한 인적 및 물적 피해가 과거와 비교하여 증가되고 있다. 이러한 피해를 예방하기 위하여 유역 수문분석이 필요하지만, 미계측 유역에서는 수문분석을 위한 수문 자료의 관측이 비교적 제한적이다. 이에 본 연구에서는 수문 자료가 제한적인 미계측 유역의 태풍사상에 의한 피해에 대비하기 위하여 개념적 강우-유출 모형의 지역화 모형을 개발하였다. 개발된 지역화 모형의 검증을 통하여 유역을 대표하는 모형 매개변수를 산정할 수 있다고 판단하였다. 향후 하천관리 및 수방시설물 설계에 기초 자료로 활용될 것으로 기대한다.

  • The purpose of this study is to investigate the home-health-care workers licensing education course in Seoul, Korea. Based on the previous research, a conceptual model was suggested explaining the dynamics of perceived educational service quality (SERVQUAL), educational satisfaction and the occupational readiness. The data set for this study drawn from the 297 self-administered surveys were analyzed with the suggested conceptual model by utilizing AMOS program. The measurement models and conceptual model fit well with the collected data set. As results of this study, 5 domains of SERVQUAL were produced including accountability, trustiness, responsiveness, sympathy, and assurance. The results of structural modeling with latent variables confirmed that SERVQUAL were influenced perceived educational satisfaction as well as occupational readiness. Among the SERVQUAL domains, accountability, trustiness, responsiveness, and assurance had significant impacts on the educational satisfaction while accountability, trustiness and responsiveness had significant direct effects on the occupational readiness. The trustiness had significant indirect effects on the occupational readiness via the educational satisfaction. Hence, the educational satisfaction had the significant impacts on the occupational readiness. Based on the findings of this study, we suggest to intense the educational program or curricular focusing on the SERVQUAL elements. Those changes will enhance self-confidence among the prospective home-health-care workers as well as public trustiness on the national long-term care program.

  • The conceptual site model (CSM) is used as a key tool to support decision making in risk based management of contaminated sites. In this work, CSM was applied in Jeonju Industrial Complex where site investigation for groundwater contamination was conducted. Site background information including facility types, physical conditions, contaminants spill history, receptor exposure, and ecological information were collected and cross-checked with tabulated checklist necessary for CSM application. The CSM for contaminants migration utilized DNAPL transport model and narrative CSMs were constructed for source to receptor pathway, ecological exposure route, and contaminants fate and transport in the form of a diagram or flowchart. The component and uncertainty of preliminary CSM were reviewed using the data gap analysis while taking into account the purpose of the survey and the site management stage at the time of the survey. Through this approach, the potential utility of CSM was demonstrated in the site management process, such as assessing site conditions and planning follow-up survey work.

  • In this study, a pseudo ship structure data model for the :.hip cargo hold structure based on STEP is proposed. The proposed data model is based on Application Reference Model of AP218 Ship Structure which is the model that specifies conceptual structures and constraints used to describe the information requirements of an application. And the proposeddata model refers the Ship Common Model framework for the model architecture which is the basis for ongoing ship AP development within the ISO ship-building group and the ship product definition information model of CSDP research project for analyzing the relationship between ship structure model entities. The proposed data model includes Space, Compartment. Ship Structural System, Structural Part and Structural Feature of cargo hold. To generate this data model schema in EXPRESS format, ‘GX-Converter’was used which enables user to edit a model in EXPRESS format and convert schema file in EXPRESS format. Using this model schema, STEP physical file containing design data for ship cargo hold data structure was generated through SDAI programming. The another STEP physical file was also generated containing geometry data of ship cargo hold which was extracted and calculated by SDAI and external surface/surface intersection program. The geometry information of ship cargo hold can be then transferred to commercial CAD system, for example, Pro/Engineer. Examples of the modification of the design information are also Presented.

  • 본 연구의 목적은 판의 경계에 대한 그리기와 면담의 결과를 바탕으로 정신모형의 유형별 분석 준거를 도출하고 이를 근거로 고등학생들의 정신모형을 밝히는데 있다. 이를 위하여 고등학교 2학년 학생을 대상으로 충돌형, 섭입형, 발산형 판의 경계에 대한 그리기 과제와 개별 면담을 병행하여 실시하고 그 결과를 정성적으로 분석하였다. 본 연구의 결과, 판의 경계에 대한 고등학생들의 정신모형의 유형은 소박한 모형(naive model), 불안정 모형(unstable model), 인과적 모형(causal model), 개념적 모형(conceptual model)의 4가지로 분류되었다. 이러한 정신모형에 대한 분석 준거는 판과 맨틀을 구분하는지, 판과 하부 맨틀의 이동을 파악하는지, 판의 경계 지형의 특징을 인식하는지, 맨틀의 대류와 지형의 특징을 관련짓고 있는지 등의 요인이다. 판의 경계에 대한 '소박한 모형'과 '불안정 모형'을 지닌 학생들은 맨틀의 대류와 지형의 생성원인을 관련짓지 못한 반면, '인과적 모형'과 개념적 모형'을 지닌 학생들은 판의 경계에서 맨틀 대류와 지형의 생성과의 인과 관계를 인식하고 있었다. 정신모형 유형에 따라 꼭꼭 획득의 방법에 관한 학생들의 믿음을 조사한 결과, 소박한 모형과 불안정 모형을 지닌 학생들은 외부적인 권위에 의존하는 경향을 나타내었다.
