The purpose of this study was to explore the marketability by developing a fresh HMR product for improving hyperlipidemia and dieting for elderly chronic disease patients and young people pursuing healthy beauty. The diet menu increased the ratio of fresh vegetables and mushrooms, and chicken breast and cheese were used as protein sources. By using whole grains, the supply of vitamins and minerals was strengthened while minimizing calories. Regarding the recipe, the diet menu was mainly prepared in the form of salads, risotto, and pasta. In the hyperlipidemia improvement menu, the proportion of fresh vegetables was increased, and as protein sources, pork shank, tofu, seafood, etc. with minimal fat were used. As a carbohydrate source, whole grains were mainly used to minimize calories while strengthening the supply of vitamins and minerals. In the recipe, it was prepared in the form of steamed or bibim-myeon, and it was also produced in a form such as paella. As a result, the developed menu was analyzed as low-calorie and evenly comprised of essential nutrients, which can satisfy palatability and nutrition.

Using the all-trans-retinol which is double-capsulated with matrix, we investigated its stability and the change of the epidermal thickness. The proprietary MDC comprise two steps of capsulation of retinol, i.e., primary microcapsulation with collagen and then secondary capsulation with gellan gum. We compared the activity of all-trans-retinol in various forms such as (1) simply in O/W, (2) in W/O emulsion, (3) in primary capsulted form in O/W emulsion, or (4) in MDC in O/W emulsion. After storage at 45$^{\circ}C$ for 4 weeks, retinol in MDC in O/W emulsion retained 92% of the activity compared to the standard material upon HPLC analysis, whereas the primary capsule gave 70%, the O/W emulsion form 47% and the W/O emulsion 78%. The retinol in MDC in O/W induced the siginificant increase in epidermal thickness compared to the vehicle.

제품디자이너는 2차원과 3차원의 조형정보를 공유하고 있지만, 최근 3차원 조형정보에 대한 중요성의 대두와 개발환경의 변화로 3차원 형상정보의 시각적인 확인에서 조형적인 실물 확인과 데이터화의 요구가 증가하고 있다. 본 연구는 CAD에 의한 3차원 모델 링 정보와 수 작업에 의한 MOCK-UP 정보에 대하여 가공 TOOLS과 REVERSE DESIGN TOOLS를 이용한 효율적인 제품 디자인 조형정보의 데이터화를 위한 방법을 제시하고자 한다.

We study totally real and complex subsets of a right quarternionic vector space of dimension n + 1 with a Hermitian form of signature (n, 1) and extend these notions to right quaternionic projective space. Then we give a necessary and sufficient condition for a subset of a right quaternionic projective space to be totally real or complex in terms of the quaternionic Hermitian triple product. As an application, we show that the limit set of a non-elementary quaternionic Kleinian group 𝚪 is totally real (resp. commutative) with respect to the quaternionic Hermitian triple product if and only if 𝚪 leaves a real (resp. complex) hyperbolic subspace invariant.

소프트웨어 제품 생산 라인(Software Product Line) 공학은 새로운 소프트웨어 개발 패러다임으로 각광받고 있다. SPL에 FORM(Feature-Oriented Reuse Method) 방법론을 적용하면, 휴대전화나 디지털TV 같이 공통점이 많은 제품군의 다양한 소프트웨어를 휘처 모델링을 통해 만들어진 재사용 가능하고 유연한 컴포넌트를 조합하여 생산해 낼 수 있다. 한편, MDA(Model Driven Architecture) 방법론은 PIM(Platform Independent Model) 을 통해 다양한 개별 플랫폼을 위한 소프트웨어를 생산할 수 있게 하는 새로운 기술을 제공한다. 위 두 가지 방법론의 장점을 조합하면 공통점을 공유하면서 다양한 플랫폼에서 동작하는 제품군의 소프트웨어를 생산하는데 도움이 된다. 이 논문에서는 FORM 방법론과 MDA 방법론을 조합하기 위해 먼저, 프로파일링 기법을 통해 UML2.0을 확장하여 FORM 아키텍처와 Parameterized Statechart 모델링이 가능하게 한다. 다음으로, 휘처가 휘처 모델과 Parameterized Statechart사이에서 일관성 있게 element의 형태로 위치하고 있는지 검증하는 일관성 규칙을 제공한다. 몇 가지 규칙은 FORM 아키텍처와 Parameterized Statechart 사이의 일관성을 검사하기 위해 고안되었다. 마지막으로, 엘리베이터 시스템의 사례연구를 통해 이 논문에서 제안하는 모델링 기법과 일관성 검사 법칙의 유효성을 제시한다.

The aim of this paper is to study the geometry of contact CR-warped product submanifolds in a cosymplectic manifold. We search several fundamental properties of contact CR-warped product submanifolds in a cosymplectic manifold. We also give necessary and sufficient conditions for a submanifold in a cosymplectic manifold to be contact CR-(warped) product submanifold. After then we establish a general inequality between the warping function and the second fundamental for a contact CR-warped product submanifold in a cosymplectic manifold and consider contact CR-warped product submanifold in a cosymplectic manifold which satisfy the equality case of the inequality and some new results are obtained.

Since software and hardware integration has became a strategic tool for companies to innovate their products, an information system that can comprehensively manage software and hardware integrated product development is critical for the current product development. This paper proposed a product data model that can support modules of related software and hardware parts in Product Data Management(PDM) integrated with Software Configuration Management(SCM). The model allows engineers to define software and hardware product structure independently, and support the integration module that can summon related software and hardware parts to build a comprehensive module for collaboration. Through the integration module, engineers can identify and examine the effectiveness of their design alternatives to other related parts form different disciplines. The product data model was implemented as a prototype PDM system and tested with an example robotics product.

We would like to consider Laplace transform of the form of fg, the form of product, and applies it to Burger's equation in general case. This topic has not yet been addressed, and the methodology of this article is done by considerations with respect to several approaches about the transform of the form of f g and the mean value theorem for integrals. This paper has meaning in that the integral transform method is applied to solving nonlinear equations.

To improve usability and recognition of product, the term, Affordance, started to be known in the design world by US recognitive psychologist, Donald A. Norman, has the meaning of providing, Act inducement, Act motivation, Expectancy or what environment provides, etc., thus as one of Mental Model, providing ever more importance not only to the everyday life goods but to the time like these days when products for information overflow. Particularly, this study is oriented toward providing basic study framework on Affordance-like approach in pursuing psychological approach in design for changing the limitless phenomena involved in environment and human body and further for inquiring into source of idea from abstract form hint latent in act and further from the act conducted everyday while peoples are unconscious.
