The Tychonoff product theorem is one of the most fundamental theorems in general topology. As is well-known, the proof of the Tychonoff product theorem relies on the axiom of choice. The converse was also conjectured by S. Kakutani and Kelley [1] then resolved this conjecture in his historical short note on 1950. However, the original proof due to Kelley has a flaw. According to this observation, we provide a correction of the proof in this paper.

A study on processing for producing cure seat radiated by Original Infrared Rays and Magnatic force. We are well aware that Original Infrared Rays and Magnatic force influence on our human body benificially. In the technical background of this research product, we treated that the product has some operations of ceramic hardwood charcoal, far infrared rays and magnetic, so it can serve large part curative values made of far infrared rays and magnetic force of ceramics. Also, in the special quality of the product deal with ceramic, hard charcoal, ferrite, gelatin what is needed in production. And among them, ferrite, ceramic and hard charcoal are introduced by the manufacturing process of the moleculeization. In concluding, this study described the manufacturing process on the basis of the worksheets and arranged the useful effect which effect on human body. There are so many symptoms in the pain of muscle. It's very various. for example, it is the cause of the liver, the spleen and a kidney function's weakening. the cause of the backbone subluxation, the cause of the shoulder joint and scapula, the cause of the sacrum and iliacjoint, the cause of hip joint and the cause of a sprain. In this thesis, we mainly deal with the method which the muscle and nervous system disease by fatigue and a sprain cure seat radiated by Original Infrared Rays and Magnatic force. then, Original Infrared Rays and Magnatic force pack up frapezius muscle, gluteus minimum muscle, gluteus medius muscle, gluteus maximus muscle, pririformis muscle around the spine. through this course the moral pressure by the nervous system disease can be treat.

본 연구의 목적은 브랜드의 이미지 및 위조품의 진품과의 제품 유사성이 명품 위조품태도에 미치는 영향을 살펴보는 것이다. 특히 지각된 브랜드 글로벌성의 조절효과와 함께 진품에 대한 태도가 위조품 태도에 미치는 영향도 살펴보았다. 연구의 결과 첫째, 브랜드 이미지는 진품(위조품)태도 모두에 긍정적인 영향을 미치며, 상징적 브랜드 이미지가 진품(위조품)태도 모두에 더 큰 영향을 미치는 것으로 나타났다. 또한 둘째, 지각된 브랜드 글로벌성의 조절효과도 확인되었다. 즉 브랜드이미지가 진품태도에 미치는 영향은 지각된 브랜드 글로벌성에 따라 차이가 유의하지 않았지만, 위조품태도에 미치는 영향은 지각된 브랜드 글로벌성이 높은 경우에 더 선호되는 것으로 나타났다. 셋째, 위조품의 진품과의 제품유사성은 위조품태도에 정(+)의 영향을 미치는 것으로 나타났고, 지각된 품질유사성이 위조품태도에 더 큰 영향을 미치는 것으로 나타났다. 넷째, 진품태도는 위조품 태도에 정(+)의 영향을 미치는 것으로 나타났다. 이와 같은 연구결과는 진품과 위조품의 관계에서 상징적인 측면의 브랜드이미지와 기능적인 측면의 제품유사성이 위조품 태도에 미치는 영향을 종합적으로 이해하는데 이론적 기초를 제공할 것이다.

환경부에서는 오염물질 다량 방출 건축자재의 효율적인 관리를 위해 "다중이용시설 등의 실내 공기질 관리법" 중 접착제의 시험방법과 방출관리기준을 동시에 개정하였다. 따라서 기존 관리수준과 개정 관리수준의 직접적인 비교가 불가능하다. 이 연구에서는 접착제의 개정된 시험방법의 각 요소들이 오염물질 방출강도에 미치는 영향들을 기존 시험방법과 비교하여 검토하였다. 이를 통하여 개정된 오염물질 방출관리기준을 평가하였다. 그 결과 접착제는 시험기간의 변경으로 인해 방출강도가 약 2.5배 약화되었고 건조시간의 변경에 따른 방출강도의 차이는 거의 없는 것으로 나타났다. 시험방법의 변경된 내용을 적용한 TVOC 방출 관리기준은 기존 방출 관리기준에 비해 약 2.1배 강화된 것으로 나타났다.

When a failure or fault is detected, the product is adjusted or design change and is returned to its original condition before the failure or fault. Continuous improvement of the FMEA system is to determine an optimum product reliability that minimizes the total cost per unit time associated with inspection, repair, and the nondetection cost.

The objective of this study is to establish a theoretical framework of factors and strategies for success , by probing into design management strategies and the resulting product development details of firms from many parts of the world that improved their images and competitiveness through industrial design. As a means for a company to successfully develop products and to survive, strategies for successful product development were unfolded by many leading businesses of industrial design, whose methods and strategies were respectively unique. International companies such as Philips, Sony, Braun, Ford, and Alessi employed industrial design to not only renew their brand perceptions, but also added values to human life by embedding exclusive designs that customers prefer in their products. They have used design as a business strategic tool, whose elemental processes are, planning, organizing, directing, and controlling. In conclusion, the successful strategies of the leading global companies' design management and product development share the following First, these companies seek design strategies that foresee upcoming changes and are ahead of their time. Second, the CEO is aware of the importance of design, has an appreciative eye for design, and puts in effort into supporting and developing his or her design sector. Third, the director is provided with the conditions in which he or she can take control of one's tasks, and has the abilities and qualities to provide visions for the future.

Researchers have employed a diversity of definitions and measurement methods for creativity. As a result, creativity research is underrepresented in the literature and the findings of different studies often prove difficult to draw into a coherent body of understanding. With regard to assessment, there are some important problems both in creativity research and practice, such as originality bias and Big-C creativity bias in teachers' perceptions about creativity and creative thinking, and additive rather than multiplicative scoring systems of creativity assessment. Drawing upon most widely accepted conceptions of the creativity construct, I defined 'student's scientific creativity' as the ability to make a product both original and useful to the student in terms of little-c creativity, and 'scientist's scientific creativity' as the ability to come up with a product both original and useful to the science community in terms of Big-C creativity. In this study, an 'Assessment Formula for Scientific Creativity' was developed, which is consisted of the multiplication of originality and usefulness scores rather than the sum of the two scores, and then, with scores calculated from the assessment formula, the scientific explanations generated by children were categorized into four types: routine, useful, original, and creative types. The assessment formula was revealed to be both valid and reliable. The implications of the assessment formula for scientific creativity are examined. The new assessment formula may contribute to the comprehensive understanding of scientific creativity to guide future research and the appropriate interpretation of previous studies.

Recommender systems are a personalized information filtering technology to help customers find the products they would like to purchase. Collaborative filtering is known to be the most successful recommendation technology, but its widespread use has exposed some problems such as sparsity and scalability in the e-business environment. In this paper, we propose a recommendation methodology based on Web usage mining and product taxonomy to enhance the recommendation quality and the system performance of original CF-based recommender systems. Web usage mining populates the rating database by tracking customers' shopping behaviors on the Web, so leading to better quality recommendations. The product taxonomy is used to improve the performance of searching for nearest neighbors through dimensionality reduction of the rating database. Several experiments on real e-commerce data show that the proposed methodology provides higher quality recommendations and better performance than original collaborative filtering methodology.

주얼리 관련 산업은 국내 시장의 불황, 디자인 개발 부재, 기능 인력의 부재와 높은 인건비 부담으로 고민에 처해 있다. 또한 소비자들의 가격대비 최대한의 가치를 가진 차별화된 제품을 원하고 있다. 주얼리 CAD와 RP 장비는 수작업에 의존했던 주얼리 제조업체에게 생산성을 단축시켜주고 다양한 디자인과 빠른 신제품을 제공해 줄 수 있다. 하지만 아직까지 RP에서 출력된 합성 수지의 직접 주조의 어려움으로 원본 작업에 필요한 만큼의 최상의 주조 소환 사이클을 알지 못하는 상태이다. 이에 본 연구자는 CAD의 활용성과 RP 장비에 관하여 분석하고, 주얼리 CAD 작업과 RP 작업을 통하여 직접 주조가 가능하도록 주조 소환 사이클을 분석하여 원본 제작에 적합한 제품을 제작할 수 있었다. 이 논문을 통해 주얼리 제품의 질적 향상과 차별성을 확보하여 다양하고 경쟁력 있는 디자인과 제품 생산에 새로운 기반을 제공하는 것에 의의를 찾고자 한다.
