The purpose of this research is to guide the development of the program for the Directive Individual Sand Box Play for the improvement of the self-esteem of children of the dissolved multicultural families. For quantitative analysis data, the scores from before and after the program were compared. The SPSS 18.0 Package was used for statistical analysis. For the qualitative analysis, the linguistic changes in B children during the session were collected and analyzed using the self-expression scale. The research period lasted for around 3 months from February 2017 to May 2017, for a total of 12 sessions which included individual activities, 1 session of group activities, and 1 night and 2 days of family camp activities featuring a total of 6 children. The main results of this research include quantitatively through the program of the Directive Individual Sand Box Play in relation to the social self-esteem capability at z=-2,200 on the level of p<.05, the significant difference was shown. Qualitatively, positive expression increased as sessions proceeded and negative expression reduced regarding the linguistic expressions by session of children B. This means that the method of the Directive Individual Sand Box which presents the topic and in addition, the process of visiting the house of a child which is the most secure environment had shown the effectiveness that increases the improvement of the self-esteem of the children of the dissolved multi-cultural families. According to the diverse special characteristics of clients, a preliminary basic framework for the mobile individual sand box program through the directive approach method will be prepared.

The purpose of this study was to examine the effects of group music therapy involving the creation of a musical play on the self-esteem, self-expression, and social skills of children. The participants were 14 first through third graders and 14 fourth through sixth graders from a children's center. Half of the children from each grade band (Grades 1-3 and 4-6) were assigned to the experimental group and the other half to the control group, for a total of 14 children in each group. The experimental group who participated in music therapy sessions focused on creating a musical play. The experimental group selected themes, made a script, composed song lyrics and music, and performed the completed musical play. The Self-Esteem Scale, Self-Expression Scale, and Social Skills Rating System (SSRS) were administered before and after the intervention. The experimental group exhibited significantly higher scores than the control group on all of the scales except subscales of the Self-Expression scale and the SSRS. The results of this study suggest that group music therapy can facilitate children's engagement in group work and that playing an important role in the group can positively impact their perceptions of themselves.

Deformable models offer an attractive approach for extracting three-dimensional boundary structures from volumetric images. However, conventional deformable models have three major limitations - sensitive to initial condition, difficult to represent complex boundaries with severe object concavities and protrusions, and self-intersective between model elements. This paper proposes a deformable model that is effective to extract geometrically complex boundary surfaces by improving away the limitations of conventional deformable models. First, the proposed deformable model resamples its elements hierarchically based on volume image pyramid. The hierarchical resampling overcomes sensitivity to initialization by extracting the boundaries of objects in a multiscale scheme and enhances geometric flexibility to be well adapted to complex image features by refining and regularizing the size of model elements based on voxel size. Second, the physics-based formulation of our model integrates conventional internal and external forces, as well as a non-self-intersecting force. The non-self-intersecting force effectively prevents collision or crossing over between non-neighboring model elements by pushing each other apart if they are closer than a limited distance. We show that the proposed model successively extracts the complex boundaries including severe concavities and protrusions, neither depending on initial position nor causing self-intersection, through the experiments on several computer-generated volume images and brain MR volume images.

SNS(Socal Network Service)미디어로 회자되는 지금의 미디어 환경에서 소통은 미디어 접근성의 중요성과 함께 어떠한 이야기를 가지고 네트워크에 참여해야 하는가에 선택과 집중이 되고 있다. 최근의 미디어 환경은 문화예술 교육안에서도 시각정보 전달을 기반으로 하는 소통구조의 미디어와 예술, 문화, IT가 결합한 컨버전스 형태의 뉴 컬처 미디어에 대한 교육적 인식을 시작하였다. 좋은 교육은 규율과 친밀성에 기반하는데 그 두 가지 모두를 가지고 있는 렌즈기반미디어리터러시는 창의적인 자기표현과 소통이라는 관점을 가지고 문화활동가와 교육생, 교육생의 가족 등 지역사회구성원들에게 사회 참여를 확장시켜 소통의 격차를 줄이는데 일정한 역할을 할 것이다. 이렇게 형성된 모델은 개별 사용자를 넘어 미디어 생산자, 수용자, 유통자 간의 새로운 관계를 모색하는 데 기여할 것이다.

급변하는 전자상거래 환경을 극복하고 이질적이고 분산되어 있는 정보들을 통합할 수 있도록 하기 위해서는 자기기술적 규약이나 소프트웨어 설계방법들이 필요하며, 그 중 온톨로지(Ontology)에 대한 필요성이 제기되고 있다. 본 연구에서는 전자상거래 통합을 위한 프레임워크를 제시하기 위해 모델링의 기반이 되는 구문론적ㆍ의미론적 통합 및 에이전트의 운용방법론에 대해 논하며, 메타 모델링에 바탕을 두는 온톨로지의 구축에 중점을 두고 설명한다. DAML(DARPA Agent Markup Language)을 사용하여 온톨로지를 구체화하며, 프로세스 표현을 위해 PSL(Process Specification Language)-ontology의 용어들을 중간 계층으로 구성하여 차용한다. 제시한 프레임워크를 통해 정보 자원들과 비즈니스 프로세스를 정의하고 공유하며 관리함으로써 중복성과 불일치성을 제거할 수 있을 것이다.

XML의 대표적인 특징은 기존의 다른 컨텐츠와는 달리 문서의 구조를 기술할 수 있다는 것이다. 구조적 정보는 활용 방법에 파라 XML문서의 다양한 처리에 있어 성능을 향상시키는 핵심적인 요소가 될 수 있다. 그러나 XML 태그의 자기 서술적인 특성에서 비롯되는 구조적 표현의 차이는 오히려 문서의 식별을 어렵게 하는 원인이 된다. 본 논문에서는 기존의 비트맵 인덱스(Bitmap Index)를 이용한 XML 문서 검색 시스템이 다양한 구조적 유사성을 판별할 수 없는 단점을 보완 가능하도록 경로 중심의 유사 문서 인식 기법을 제안한다. 이 기법은 '경로 구성 유사도'와 '유사 경로 테이블'을 통해 기존의 비트맵 인덱스가 갖는 유사 경로를 인식하지 못하는 단점을 해결하고 검색의 유연성을 부여함으로써 보다 양질의 검색 결과를 도출할 수 있다. 또 이것은 기존 시스템의 Bit-wise 연산에 완전히 이식됨으로써 비트맵 인덱스의 장점인 빠른 성능을 그대로 유지할 수 있게 된다.

The purpose of this study is to empirically analyze the factors influencing user's intention to share photos in Instagram, a representative SNS whose main function is photo sharing. For this purpose, based on the results of reviewing related literature such as uses and gratification theory, the motivation factors for use that are expected to influence the formation of positive perception of Instagram users are derived. The results of empirical analysis of 251 Instagram users are as follows. First, the archive, self-expression, and social relations of Instagram have a positive effect on the usefulness. Second, Instagram's self-expression, social relationship and playfulness were found to have a positive effect on favorable attitude. Lastly, the user's perceived usefulness on Instagram has a positive effect on the favorable attitude, and both the usefulness and favorable attitude have a positive effect on the to photo sharing intention. Based on the results of this study, strategic implications were drawn to enable the spread of services through the positive recognition and the improvement of photo sharing intention of Instagram users.

We have developed an algorithm based on the method of integral equations to simulate the magnetotelluric (MT) responses of three-dimensional (3-D) bodies in a layered half-space. The inhomogeneities are divided into a number of cells and are replaced by an equivalent current distribution which is approximated by pulse basis functions. A matrix equation is constructed using the electric Green's tensor function appropriate to a layered earth, and is solved for the vector current in each cell. Subsequently, scattered fields are found by integrating electric and magnetic Green's tensor functions over the scattering current About a 3-D conductive body near the earth's surface, interpretation using 2-D transverse electric modeling schemes can imply highly erratic low resistivities at depth. This is why these routines do not account for the effect of boundary charges. However, centrally located profiles across elongate 3-D prisms may be modeled accurately with a 2-D transverse magnetic algorithm, which implicitly includes boundary charges in its formulation. Multifrequency calculations show that apparent resistivity and impedance phase are really two complementary parameters. Hence, they should be treated simultaneously in broadband MT interpretation.

Creativity is the thinking ability and the expression of new image by imagination as a problem recognition and way of solution. This study aims to search for the creativity theory of body movement and to analyze the creativity factor. According to the study, the creativity of body movement needs four steps: movement awareness, movement design, movement discovery and movement use. The use of new image through self-perception and self concept brings about a creative improvement in the problem recognition and its resolution function. In conclusion, the creativity of body movement means the infinity of body movement as 'the third energy' and 'the flexibility of flow' by interaction.
