The current web implementation largely falls into process-oriented and object-oriented methods. Both ways implement the programs to be used for simple design of external outfit and auxiliary function of hybrid webs and it might lead to cost problems arising from waste of time and man-power to develop with it. Therefore, managed structural system programming which can be applied under .NET framework is suggested in a bid to solve these problems. The structural system design method under .NET environment by applying CS concept prefers to adopting the optimized design configuration suited to proper interfaces of UI configuration, which offers the environment to maintain the inheritance relationship by taking form of the balanced class allotment by domain, and continue to keep the connectivity between UX and UI which leads to application of interface of UX objects as form of objects through connection with objects in class design process. This development method enables programs to be implemented focused on representation methods of UI and UX, and helps relieve much of the burden on development costs.

In accordance with the changing of society, remarkable increase in knowledge and information, the competencies to choose and use proper information in various domains are considered as an important skill. As one of the methods in developing these competencies, it is emphasized that a problem-based learning can make student understand and use knowledge by solving the contextualized problem. However, it is skeptical of learner's development of competencies to use knowledge by solving well-defined given problem. Therefore it is required that students be allowed to develop the competency to find problem through experiences to determine and evaluate the purpose of the problem and method. The purpose of this study is to understand how undergraduate students use science or technology in finding a problem. In this line, this study articulated four cases conducted by participants who engaged in convergence teaching-learning program. And this study investigated the participants' process of problem-finding, method and reason to apply science or technology. The results were drawn by analyzing interviews and written data, including their proposal, a poster, and final reports. Participants changed the form of problem from initial ill-structured one into a concrete one, where the participant could derive a detailed solution. Science or technology applied as the detailed example to convert problem into a concrete form, or as the analyzing tool or theoretical background of problem to make a link with other domain. Their reason of applying science or technology could be summarized in 'personal interest based on prior experience' and 'alternatives to resolve a dissatisfaction.' Based on the result, this study suggests holistic approach that is included in both intuitive thinking and logical thinking and metacognitive regulation to stimulate problem-finding in problem-based learning program.

The purpose of this study was to development a model of the practical skill instruction of the special subject using the problem-based learning in the technical high schools For the study, various literature researches were reviewed intensively about problem solving process, problem -based learning, and learning principals. The process of the practical skill instruction using the problem-based learning was composed with planning, executing, testing and evaluating. In this practical skill instruction using the problem-based learning, the teacher serves as a coach or guide for students' learning. As a facilitator, the teacher challenges, questions, and stimulates the students in their thinking, problem solving and self-directed study. In this process, students represent problem by thinking aloud, assuming responsibility for their own learning, having self-directed study as well as doing cooperative study, and as a result, education changes move from teacher-centered to student-centered.

Objectives: The aim of this study was to establish the basic data for adolescents' mental health states in a community. Methods: 466 middle school and high school students were analyzed by visit-survey with an organized questionnaire from March to June 2008. K-YSR for measurement of mental health was used. Results: The score of total behavior (p<0.01), anxious/depressed (p<0.05), though problems (p<0.001), attention problems (p<0.001), aggressive behavior (p<0.01) and internalizing problems (p<0.05) in girls appeared significantly higher as compare to those the boys. Also, total competence (p<0.05) in high school students appeared significantly lower as compare to those middle school students. Withdrawn (p<0.01) in high school students appeared significantly higher as compare to those middle school students. The though problems (p<0.001) and aggressive behavior (p<0.05) in middle school students appeared significantly higher as compare to those high school students. The distribution of clinical group was school 93.8%, total competence 32.6%, attention problems 8.8%, total behavior problems 8.6%, anxious/depressed 7.7%, aggressive behavior 6.4% et. al. The social (p<0.05), anxious/depressed (p<0.05), attention problems (p<0.01), internalizing problems (p<0.05) and externalizing problems (p<0.05) in girls of clinical group were more frequent significantly as compared to those the boys of clinical group. Also, the social (p<0.01) in middle school students of clinical group was more frequent significantly as compared to those the high school students of clinical group. Conclusions: This study result will be significant in that it can provide basic data for the school mental health services.

인간의 추론 능력이란 문제에 주어진 조건을 보고 문제 해결에 필요한 것이 무엇인지를 논리적으로 생각해 보는 것으로 문제 상황 속에서 일정한 규칙이나 성질을 발견하고 이를 수학적인 방법으로 법칙을 찾아내거나 해결하는 능력을 말한다. 이러한 인간인지 능력과 유사한 인공지능 시스템을 개발하는데 있어서 핵심적 도전은 비구조적 데이터(unstructured data)로부터 그 개체들(object)과 그들간의 관계(relation)에 대해 추론하는 능력을 부여하는 것이라고 할 수 있다. 지금까지 딥러닝(deep learning) 방법은 구조화 되지 않은 데이터로부터 문제를 해결하는 엄청난 진보를 가져왔지만, 명시적으로 개체간의 관계를 고려하지 않고 이를 수행해왔다. 최근 발표된 구조화되지 않은 데이터로부터 복잡한 관계 추론을 수행하는 심층신경망(deep neural networks)은 관계추론(relational reasoning)의 시도를 이해하는데 기대할 만한 접근법을 보여주고 있다. 그 첫 번째는 관계추론을 위한 간단한 신경망 모듈(A simple neural network module for relational reasoning) 인 RN(Relation Networks)이고, 두 번째는 시각적 관찰을 기반으로 실제대상의 미래 상태를 예측하는 범용 목적의 VIN(Visual Interaction Networks)이다. 관계 추론을 수행하는 이들 심층신경망(deep neural networks)은 세상을 객체(objects)와 그들의 관계(their relations)라는 체계로 분해하고, 신경망(neural networks)이 피상적으로는 매우 달라 보이지만 근본적으로는 공통관계를 갖는 장면들에 대하여 객체와 관계라는 새로운 결합(combinations)을 일반화할 수 있는 강력한 추론 능력(powerful ability to reason)을 보유할 수 있다는 것을 보여주고 있다. 본 논문에서는 관계 추론을 수행하는 심층신경망(deep neural networks) 중에서 Sort-of-CLEVR 데이터 셋(dataset)을 사용하여 RN(Relation Networks)의 성능을 재현 및 관찰해 보았으며, 더 나아가 파라미터(parameters) 튜닝을 통하여 RN(Relation Networks) 모델의 성능 개선방법을 제시하여 보았다.

The study identifies the major themes for integration education program which enhances the relationship between the north Korean refugees and their south Korean hosts. The themes were selected based on qualitative analysis of the socio-cultural conflicts experienced by the refugees and the hosts in the acculturation process. Twenty-eight north Korean refugees over age 20 participated in semi-structured interviews, and two south Korean groups in close contact with the refugees, police and volunteer teachers, were interviewed in focus groups. The interviews were recorded and transcribed for categorization and coding. The study views the acculturation issue as the two-sided integration task for both the north Korean refugees and the south Korean hosts rather than as the one-sided acceptance and assimilation task for the refugees.
