This study is conducted for the purpose of conceptualizing a choral communication model. first, the musical communication models analyzed to know how it can apply in the choral music. As a result, we take the music communication is the interaction between composers, performers and audience. But the choral music have properties not found in the general music. The choral music is the need for internal communication process before performing music. First, the conductor is to interpret the music. Next, choral members are shared the interpretation of music. This internal communication be conducted properly, musical communication with the audience will be successful. The trial model provided for in this study will be a guideline for successful communication in the choral music, theoretically or practically.

For the past 20 years, the growth and development of university-design-educational institutes contributed to the industrial development of our country. Due to the technological fluctuation and changes in the industrial structure in the latter half of the 20th century, the enterprise is demanding professionally-oriented design manpower. The principle which appears from instances of the advanced nations is to accommodate the demands in social changes and apply them to educational design programs. In order to respond promptly to the industrial demand especially, the advanced nations adopted "multidisciplinary design education programs" to lead innovation in the area of design globally. The objective of the research consequently is to suggest an educational system and a program through which the designer can be educated to obtain complex knowledge and the technique demanded by the industry and enterprise. Nowadays in order to adapt to a new business environment, designers specially should have both the knowledge and techniques in engineering and business administration. We suggest that the IPDI, a multidisciplinary design educational system and program is made up of the coordinated operation of major classes, on-the-job training connection, educational system for research base creation, renovation design development program for the application and the synthesis of alternative proposals about the training facility joint ownership by connecting with the education of design, business administration and engineering.

Big data research plays a role of supplementing existing social science research methods. If the survey and experimental methods are somewhat inaccurate because they mainly rely on recall memories, big data are more accurate because they are real-time records. Social science research so far, which mainly conducts sample research for reasons such as time and cost, but big data research analyzes almost total data. However, it is not easy to repeat and reproduce social research because the social atmosphere can change and the subjects of research are not the same. While social science research has a strong triangular structure of 'theory-method-data', big data analysis shows a weak theory, which is a serious problem. Because, without the theory as a scientific explanation logic, even if the research results are obtained, they cannot be properly interpreted or fully utilized. Therefore, in order for big data research to become a methodological innovation, I proposed big thinking along with researchers' efforts to create new theories(black boxes).

전자제품의 다양한 기능들의 융복합화 및 휴대 편의성 경향은 이제 더 이상 새로운 것이 아니다. 이러한 추세에 따라 전자부품들은 모듈화 되고, 휴대하기 용이해 지고 있다. 또한 다양한 제품 디자인에 적용하기 위해 제품에 장착되는 부품의 기구적 위치 배열의 한계 또한 제약 받고 있다. 따라서 최근의 전자부품은 모듈화 되고 있으며, 기구적 한계를 극복하기 위한 Flexible 모듈의 사용이 증가하고 있다. 또한 양산측면에서 Roll-to-Roll(R2R) 방식을 적용함으로써 생산성을 극대화 하고 있다. 이때 R2R 적용을 위해서는 제품이 굴곡 될 수 있도록 유연성이 보장되는 Bendable 전자모듈의 개발이 필수적으로 요구되고 있다. Flexible 기판은 더 이상 새로운 기술이 아니지만, Felxible 기판 내부에 칩이 내장되고, 회로가 형성되어 자체적으로 기능을 수행할 수 있도록 한 Bendable 전자모듈을 R2R 방식으로 제조하는 기술은 매우 새로운 접근이라 할 수 있다. 이러한 기술개발이 현실화 된다면, Wearable Electronics 및 Flexible Display 등 다양한 전자제품에 응용될 수 있을 것으로 기대된다. 그러나 이러한 제품의 상용화를 위해서는 Bendable 전자모듈에 대한 신뢰성이 확보되고, 제품으로써의 수명이 보증되어야 한다. 신규 개발되는 제품의 신뢰성 검증항목이나 수명평가 모델은 현재까지 제안되지 않고 있는 실정이다. 또한 다양한 사용 환경에서 고장(Failure) 발생을 유발하는 스트레스 인자(Stress Factor)를 도출함으로써, 가속시험 또는 신뢰성 검증을 위한 인가 스트레스를 선정할 수 있다. 그러나 이러한 고장물리를 기반으로 스트레스 인자를 해석한 결과는 아직 보고되고 있지 않다. 따라서 본 연구에서는 $50{\mu}m$ 두께의 Si Chip에 저항변화를 관찰하기 위한 회로를 형성한 후 폴리이미드 기판을 이용하여 Si Chip이 임베딩된 Bendable 전자모듈을 제작하였다. 전자모듈의 실사용 환경에서의 수명예측을 위한 사전단계로써 고장물리에 기반한 고장모드와 고장메카니즘을 해석하는 것이 최우선 수행되어야 하며, 이를 바탕으로 고장을 유발하는 스트레스 인자를 도출 하였다. 고장도출을 위해 시제품은 JEDEC J-STD-020C의 MSL시험, 고온가압시험, 열충격시험 및 고온저장시험을 각각 수행하였으며, 이로부터 발생된 각각의 고장유형을 분석함으로써 스트레스 인자를 도출하였다. 또한 모아레(Moire) 간섭계를 이용하여 제작된 샘플의 온도변화에 따른 변형해석을 수행하였고, 동시에 Half Symetry Model을 이용한 유한요소해석(FEA)을 수행하여 변형해석 및 스트레스 유발원인을 도출하였다. 이 결과로 부터 고장물리 기반의 고장해석과 Moire 분석 그리고 시뮬레이션 해석 결과를 바탕으로 Bendable 전자모듈의 고장유발 스트레스 인자를 해석할 수 있었다.

Sensitivity analysis is used to determine the effect of a change in a design parameter on the total system, and the calculated sensitivity is an important indicator of the improvement of a structure. In this study, we investigated the method of deriving and analyzing the sensitivity of design parameters by using finite element analysis and the method of improving a structure by using sensitivity analysis results. Design parameters for weight reduction design were selected using actual semiconductor inspection equipment that requires structural improvement, and the sensitivity to design parameters was calculated by using and finite difference method. We propose an improvement method that can reduce the weight while maintaining the transient response required by the equipment. By using the results of the sensitivity analysis through finite element analysis and finite difference method, we can create a structurally improved design that satisfies the desired stress or displacement by improving the design of the structure. Therefore, sensitivity analysis is applicable to various fields as well as semiconductor inspection equipment.

The configuration analysis for the image appeared in the storyboard as the 1st stage to change the scenario to the image expressed the visual phenomenon image starting from the literalism. The simultaneity of description on the interpretative level of the narrative description may describe various information multiple simultaneously, the relationship has been presented as a lot of these information has been weaved as one episode. The incident time of narrative description as the scene described mainly objectively and illustratively has been used usefully to present the accurate information for characters or incidents. The time series of narrative description appeared as one episode by expressing various spaces or images under the continuity of flow according to the time. The collision image seen from the angle of internal ignition played a role to create the meaning colliding into each other or interconnecting symbolic effects appeared as respectively fragmented image, the continuity of space played a role of expressing the different symbol when the image of completely different space is connected to one context, the continuity of time as well makes a different symbolism by interpreting symbols appeared as each images under the flow of time. These results show that the narrative description may be expressed in accordance with the narrative structure from the viewpoints of narrative description, but the internal ignition may be interpreted through the cultural and periodical background widely known in those years based on the experience and information capability the audiences are keeping not by any descriptive structure. Images appeared in the internal ignition appeared by colliding into each other or amplifying mutually no related scenes and revealing the overall symbolism by reinterpreting again.

For the past half century, researches on human psychology have witnessed the flourish of various research tools in this area. Many psychological measures were developed to get objectified data and this trend has lead to the abundance of quantified results. However, considering subjectiveness and refinements of human experience, the research focused on individual's unique perspectives and explanations is needed also. In this vein, this study proposed the usefulness of photography as a research tool for human psychology. With the wide spread of smart phone, taking photo became the everyday activity for modern people and also a part of a public art. If photo could play an efficient and unique role to study human psychology, the depth and width of human understanding might change dramatically in positive way. Two friendship photos were presented to suggest the possibility of photo as a research tool and final considerations of using photo were suggested briefly.
