Traffic congestion cost is more likely to occur in the inner city than interregional road, and it accounts for about 63.39% of the whole. Therefore, it is important to mitigate traffic congestion of the inner city. Traffic congestion in the urban could be divided into Recurrent congestion and Non-recurrent congestion. Quick and accurate detection of Non-recurrent congestion is also important in order to relieve traffic congestion. The existing studies about incident detection have been variously conducted, however it was limited to Uninterrupted Traffic Flow Facilities such as freeway. Moreover study of incident detection on the interrupted Traffic Flow Facilities is still inadequate due to complex geometric structure such as traffic signals and intersections. Therefore, in this study, incident detection model was constructed using by Artificial Neural Network to aim at urban arterial road that is interrupted traffic flow facility. In the result of the reliability assessment, the detection rate were 46.15% and false alarm rate were 25.00%. These results have a meaning as a result of the initial study aimed at interrupted traffic flow. Furthermore, it demonstrates the possibility that Non-recurrent congestion can be detected by using car navigation data such as car navigator system device.

In this study, we investigated subjective perceptions of one retailer's PB products for large retailers by applying the Q methodology to examine subjective trends of consumers who purchased and experienced PB products at home. In this study, we examine how HMR-type PB products developed and released by large retailers according to the demographically changing social structure represent the meaning and subjective acceptance of PB products in a single licensee through Q methodological studies. The purpose of this paper is to propose various direction and improvement plan of food product development and release for one license of large distribution company in the future. Based on these research problems, five types of type analysis results were derived. Specifically, the first type (N = 5): Brand image trust type, the second type (N = 5): NB product preference type, the third type(N = 2): Easy cooking preference type, and fourth type (N = 2): Pursuing taste for price type and fifth type (N = 2): Quantitative pursuit for price type.

This study set out to investigate the adaptation process and experiential structure of those children who went through sexual abuse by looking into their inner worlds in order to understand what kind of meaning sexual abuse had on them. For that, the investigator conducted in-depth interviews with 13 children aged 8~16 who lived at the shelter after experiencing sexual abuse. The methodology of Grounded Theory by Strauss and Corbin(1990) was used to analyze raw data. The analysis results indicate that the core theme of the adaptation process among the children living at the shelter after sexually abused by kin and kith was "hoping to appear the same as others." According to the results, the core phenomenon was "blaming the victims." The causal conditions include "broken families," "antihuman sexual abuse," "making sexual abuse a public issue," and "the trap of the family." The contextual conditions include "the chain named family," "family as the last fortress" and "structural enforcement of silence." The intervening strategies was "dual emotions toward the shelter." The action/interaction strategies include "aftermath of violence" and "trying to escape." The consequences were "preparation for the future" and "uncertain future." The identified stages include the confusion, keeping the secret, leaking the secret to others, intervention by others, social support and challenge and adjustment stage. The three identified types were "withdrawal and avoidance," "settling down in reality" and "overcoming and challenging." Based on the analysis results, discussions were made about the social welfare plans and intervention strategies in the conclusion.

I analyzed about the Ruyi(儒醫)'s mind on this article. Ruyi led and Nei-Jing (內經)'s Xin(心)-Shen(神)-Qingzhi(情志) it developed a medical theory. Qingzhi comes true confucianism aims became the good tool. Junhuo(君火)-Xianghuo(相火) for them to apply medically. Junhuo-Xianghuo is a possibility of seeking a ground from Nei-Jing. Junhuo governs all body and Xianghuo takes charge of the role which raises the body. It is to divide huo(火)with relationship of the king and the liege man. After Yuan-dynasty(元代) Ruyi medical sciences grasped Junhuo-Xianghuo with confucianism structures. The representative scholar is Zhu zhen-heng(朱震亨). I analyzed Zhu's Junhuo-Xianghuo. Xin-huo rules over the body. For expression of active Chi, it set the dual structure-'Junhuo-Xianghuo'. And it divided Junhuo from desire and sentiment. And Zhu zhen-heng attempted Taoism and medical science and Confucianism from the process under integrating. And analyzed Junhuo-Xianghuo Confucianism meaning. With Junhuo-Xianghuo and Confucianism described a relationship in the Zhu zhen-heng's theory. Finally view of Ruyi, medical science is the method of confucianism aims comes true.

Various studies are being actively conducted to show that the real-time visualization technology that combines BIM (Building Information Modeling) and AR (Augmented Reality) helps to increase construction management decision-making and processing efficiency. However, when large-capacity BIM data is projected into AR, there are various limitations such as data transmission and connection problems and the image cut-off issue. To improve the high efficiency of visualizing, a mesh optimization algorithm based on the k-nearest neighbors (KNN) classification framework to reconstruct BIM data is proposed in place of existing mesh optimization methods that are complicated and cannot adequately handle meshes with numerous boundaries of the 3D models. In the proposed algorithm, our target BIM model is optimized with the Unity C# code based on triangle centroid concepts and classified using the KNN. As a result, the algorithm can check the number of mesh vertices and triangles before and after optimization of the entire model and each structure. In addition, it is able to optimize the mesh vertices of the original model by approximately 56 % and the triangles by about 42 %. Moreover, compared to the original model, the optimized model shows no visual differences in the model elements and information, meaning that high-performance visualization can be expected when using AR devices.

In safety-critical systems, software defects may have serious consequences. Therefore, defects should be considered during the requirements specification process, which is the first step of a software development lifecycle. Stakeholder requirements that are usually written in natural language are difficult to derived, and there may also be defects due to ambiguity and inaccuracy. To address these issues, we propose a requirement specification method using a standardized Boilerplate and a GSN Model. The Boilerplate is a semi-standard language that follows a predefined format. Due to its ability to provide a consistent representation of the requirements, boilerplate helps stakeholders avoid ambiguities about what they mean and to define the exact meaning of the requirement. Meanwhile, GSN is recognized notation to prepare a Safety Case to prove to authorities that a system is safe. It can be expressed as a functional goal, e.g., Safety Evidence, etc. The proposed study allows an analyst to easily identify a fault from the early stage of the software development lifecycle. The Boilerplate and GSN Model are designed to specify the requirements of safety critical systems and to prove safety conformity through a connection with Safety Evidence. In addition, the proposed approach is also useful to develop secure software by correcting deficiencies in the requirements found during this process.

This study aims to find an effective way to present essential science concepts in national science curriculum through international comparisons. Next Generation Science Standard (US), Ontario Science Curriculum (Canada), Australia Science Curriculum, and British/English Science Curriculum were selected for comparison. In science curriculum documents, these countries used terms such as 'Key ideas,' 'Big ideas,' 'Key concepts,' 'Disciplinary core ideas.' and 'Fundamental concepts' to present essential concepts of science. This study reviewed the characteristics of the meaning, the status, and the role of essential concepts country by country. The result shows essential concepts have been used with different meanings and statutes in each case. Furthermore, various roles were performed through essential concepts in order to organize their science curriculum. From these foreign nation's cases, this study proposes several ways to present essential science concepts based on results. First, interdisciplinary integrated concepts were needed to organize an integrated science curriculum. In science curriculum documents of the United States, Canada, Australia and England, two types of terms were used in order to structuralize an integrated science curriculum. Second, essential concepts should include concepts related with function and value as well as scientific knowledge. Third, essential concepts need to be presented in such a way as to show specific contexts. Therefore, selecting appropriate contents and structure are needed to be able to improve the way to present essential concepts in Korea's educational environment.

Flipped classroom has used widely in university in that its unique structure can facilitate learners' higher-thinking skills and promote competencies. Learners are expected to extend knowledge through performing online and offline, but they have difficulty in understanding their roles and specific behaviors to achieve the learning goals in the flipped learning. Therefore, a guidance for students has been required to support learners' mastery learning. The purpose of this study is to identify successful learners' characteristics in terms of "competency". For this, three-phased competency modeling was employed. In Phase I, Behavioral Event Interviews were conducted with eight learners of the flipped classroom. In Phase II for identifying competencies and developing a competency model, the data was coded, followed by testing reliability of the coding. Based on the meaning codes, competencies and behavioral indexes were developed. The final competencies consist of learning orientation, learning management, feedback seeking, peer interaction, and knowledge extension. In Phase III, validation of the competency model was conducted by explanatory factor analysis. As last, competencies were aligned by the two-phase of the flipped classroom. The finding will be used as the guidance for the learners and instructors in the flipped classroom.

This study is to study Jung's analytical psychology and to study counseling process and counseling techniques based on the counseling theory derived from it. Jung divides the counseling process into four stages based on analytical psychology. The first stage is confession, and the prototype of analysis therapy is confession. The first step in the treatment process is to share secrets and reveal suppressed emotions. The second stage is elucidation, a process that clarifies by shedding light on the contents induced by the transfer. The third stage is the level of education. Explanation makes my counselors intelligent, but leaves them still in an incompetent state. At this stage, treatment goes beyond insight to train as a responsible client. The fourth stage is transformation. In the transformation phase with inner counselors, not only the debaters, but also the therapist is in the "in-analysis." Jung's counseling technique uses six things: dream analysis, use of symbols, word link test, symptom analysis, case history and MBTI. In conclusion, analytical psychology counseling has enabled, first, a more in-depth approach and understanding of the human mind, especially the unconscious world. Second, analytical psychology counseling has enabled us to recognize that all humans are human communities with a common mental structure through the concept of unconsciousness and archetypes. Third, analytical psychology counseling has allowed you to look at the meaning and purpose of life from a new perspective. Therefore, Jung emphasized that he should not be seen as having a pathological problem with patients, but as an omnipotent human being who wants to realize its fullness on his own.

The purpose of the present study was to develop a convergent education contents for dementia prevention, operating on the web network applying modern information technology(IT). At the preparation stage, local and worldwide literatures related to dementia were analyzed followed by surveying industry demands, based on which the program was designed and developed. In the following enhancement stage, the program was modified as much as possible by advices obtained from experts in various fields. Development results of the present program are summarized as follows. Firstly, 645 intellect development model to prevent dementia was established through peer review and verification of convergent education theories by expert groups. This model was named as "Garisani" meaning "cognition capable of judging objects" in the Korean language. Secondly, 'Find a way' and 'Connect a line' modules were developed in the numeric field as well as 'Identify a letter(I, II)' modules, in the language field for web-based left brain training program. Thirdly, 'Find my car' and 'Vision training' modules in the attention field and 'Object inference' and 'Compare pictures' modules in the cognition field were developed for web-based right brain training program. Fourth, 'Pentomino' and 'BQmaze'(Brain Quotient and maze) modules in the space perception field and 'Visual training' in the memory field were developed for web-based left and right brains training. Fifth, all results were integrated leading to a 52 week Garisani convergent education program for dementia prevention.
