This study inquired about the convergence learning program for childhood based on Erikson's play theory and design education for children's behavior development. I analyzed the convergence learning programs of Summer Camps in the Pacific Science Center, Galileo Learning. The contents of the programs show the most used imaginary and symbolic contents that represent the real-world problems which are related design thinking process. The curriculums and structure of the programs are based on the design thinking method and K-12 theory. The visual thinking method and the applications are used for expressing their creativity and approaching the technical skills easily. The play concept theory is an affirmative way to strengthen the children's psychological and social development. Therefore, the convergence learning program should integrate the design thinking process and apply the play concept theory for supporting and developing the children's behavior.

The ship hull is accomplished by assembling various curved surfaces. There are numerous existing methods for ship hull processing, which need certain appropriate processing methods to enable it to be more efficient. The curved hull plates can be divided into convex region and saddle region. It is common to use line heating method to form a saddle region, when it comes to a convex region, it will be triangle heating method to be utilized. A precise analysis for curvature domain is required for the application of proper processing method. There exist various problems on existing calculation methods of curvature domain. Therefore, a more powerful method is demanded to it more accurately. In this study, a method called Dual Contouring is applied to extract curved surfaces, which is able to improve accuracy of extracted area. Based on all above, a best-suited heat processing method should be selected.

With development of digital technology and build-up of global network in the 21st century, Korea has recklessly accepted Western information and culture in recent years, thus causing damages to out identity. In the situation, restoration and development of traditions in a modern way will contribute to the creation of contemporary interiors. This study has analyzed and assessed the process through which traditional decorative elements have applied to contemporary interior decorations over the past ten years with a view to identify the trend of expressing traditional elements in comtemporary interiors. Designs that have applied traditional elements in a transfigure expression method amounted to 77 pieces, accounting for $43\%$ of the total investigated 178 designs, which was followed by 48 designs ($27\%$) of metaphor expression method and 39 designs ($22\%$) of symbol expression method, which express the tradition as interpreted by the designer. Designs that have adopted direct expression method amounted to no more than 14 pieces, accounting only for $8\%$ of the total designs. This result suggests that transformative, metaphoric and symbolic expressions that simplify or transform the original forms we more frequently used In the applications of traditional elements to modern interiors rather than directive expression that reproduces the original form as it was.

반도체(semiconductor) 기술은 1950년대에 집적 회로(integrated circuit, IC)가 발명된 이후 오늘날까지 급속한 발전을 거듭하고 있다. 하나의 완전한 반도체를 제조하기 위해서는 매우 다양하고 긴 공정을 거쳐야 한다. 반도체 제조 생산성을 높이기 위하여 공정들이 종료되기 전에 미리 이상(fault)을 발견하기 위한 이상탐지 및 분류(fault detection and classification, FDC)에 대한 많은 연구가 진행되고 있다. 이를 위하여 다양한 반도체 장비에 갖가지 종류의 센서를 부착하여 일정한 시간 간격으로 원하는 값을 측정한다. 이러한 측정 값은 실수 값들의 연속이므로 시계열(time-series) 데이터의 일종이다. 본 논문에서는 반도체 공정에서의 이상탐지 및 클러스터링을 수행하는 알고리즘을 제안한다. 제안된 알고리즘은 시계열 데이터를 심볼릭 표현법(symbolic representation)으로 변환하여 이상을 탐지하는 기존의 알고리즘을 수정한 것이다. 본 논문의 공헌은 일반적인 시계열 데이터에 대한 기존의 이상탐지 알고리즘을 수정하여 반도체 공정 데이터에 대해서도 활용할 수 있음을 보일 뿐만 아니라, 이상탐지 및 클러스터링의 정확성을 높이는 실험 결과를 제시하는 것이다. 실험 결과, 본 논문에서 제안한 알고리즘은 긍정 오류(false positive) 및 부정 오류(false negative)를 모두 발생하지 않았다.

This study investigated the purchase intention of green fashion products based on Rogers' Diffusion of Innovation theory and compared the differences between Korean and British consumers. In order to identify the impact of personal characteristics, this study also examined the effects of fashion innovativeness and LOHAS tendency on perceived attributes of innovation and intention to purchase. With a convenience sampling method, a survey questionnaire was distributed at popular fashion streets in each country. A total of 426 data were obtained, 203 from the UK and 223 from Korea. About 52% were females, and 69% were in their twenties. A factor analysis generated two LOHAS factors (health concerns and eco concerns) and four attributes of green fashion products (image improvement, symbolic superiority, observability, and compatibility). Two types of green fashion products (organic cotton t-shirts and organic cotton t-shirts with an environmental message) were provided to measure the purchase intention, respectively. The findings were as follows. British consumers were more likely to show LOHAS tendency and to perceive positive advantages of green products compared to Koreans; in addition, British consumers presented higher mean scores on the purchase intentions of organic cotton products. Fashion innovativeness was significant to predict image improvement and symbolic superiority, while eco concerns were significant in compatibility for both nations. Compatibility was important for both countries in order to explain the intention to adopt two types of organic products. In addition, image improvement was another predictor for purchase intention of organic t-shirts with an environmental message. Managerial implications were provided.

The purpose of this study is to understand what two models of SOLO taxonomy and van Hiele theory suggest and find out what relation there is between the category system of the SOLO taxonomy and the thinking level of the van Hiele theory. The van Hiele theory describes in line of ranking level so that it may increase the teaching effects by putting together a class, which takes into consideration the students thoughts. The SOLO taxonomy focused on the response mode of the students rather than the thinking level or the developmental stage of them to pursuit the method that can describe the students understanding in depth quality-wise. Although the SOLO taxonomy and the van Hiele model seem to have different form and character from outside in terms of their goals, a closer examination reveals that the two stances have much in common and that the models are complementary. Although the van Hiele placed more focus on the thoughts, because the conclusion was based on the students responses, the van Hiele theory can be interpreted within the structure identified in the SOLO model. In this study, we have tried to understand how the response structure form the SOLO taxonomy and the thinking level of the van Hiele theory are related, based on the studies of Pegg and Davery1998). If you briefly look at them, there are following corresponding relation between the SOLO taxonomy and the van Hiele theory. a) The relational level(R) in iconic moe is van Hiele level 1. b) The multisturctural level(M$_2$) in the second cycle of concrete-symbolic mode is van Hiel level 2. c) The relation level(R$_2$) in the second cycle of concrete-symbolic mode is van Hiele level 3. d) The unistructural level(U$_2$) in the second cycle of formal mode is van Hiele level 4. e) The postformal mode is van Hiele levle 5. Though it would be difficult to conclude that these correspondences were perfectly done, if you look at their relation, you can see that the learning process of the students were not carried out uniformly. Therefore, by studying the students response structure, using the SOLO taxonomy, and identifying the learning cycle and understand the geometrical concept more in depth.

Modern society's technological and economical changes require high-level education that involve critical thinking, problem solving, and communication with others. Thus, today's perspective of mathematics and mathematics learning recognizes a potential symbolic relationship between concrete and abstract mathematics. If the problems engage students' interests and aspiration, mathematical problems can serve as a source of their motivation. In addition, if the problems stimulate students'thinking, mathematical problems can also serve as a source of meaning and understanding. From these perspectives, the purpose of my study is to prove that mathematical modeling tasks can provide opportunities for students to attach meanings to mathematical calculations and procedures, and to manipulate symbols so that they may draw out the meanings out of the conclusion to which the symbolic manipulations lead. The review of related literature regarding mathematical modeling and model are performed as a theoretical study. I especially concentrated on the study results of Freudenthal, Fischbein, Lesh, Disessea, Blum, and Niss's model systems. We also investigate the emphasis of mathematising, the classified method of mathematical modeling, and the cognitive nature of mathematical model. And We investigate the purposes of model construction and the instructive meaning of mathematical modeling. In conclusion, we have presented the methods that promote students' effective model construction ability. First, the teaching and the learning begins with problems that reflect reality. Second, if students face problems that have too much or not enough information, they will construct useful models in the process of justifying important conjecture by attempting diverse models. Lastly, the teachers must understand the modeling cycle of the students and evaluate the effectiveness of the models that the students have constructed from their classroom observations, case study, and interaction between the learner and the teacher.
