  • Computer aided process planning (CAPP) keeps an important role between the design and manufacturing engineering processes. A CAPP system is a digital link between a computer aided design (CAD) model and manufacturing instructions. CAPP have been researched and applied in manufacturing filed, however, one manufacturing area where CAPP has not been extensively researched is rapid prototyping (RP). RP is a technique for creating directly a three dimensional CAD data into a physical prototype. RP enables to build physical models automatically and to use to reduce the time for the product development cycle as well as to improve the final quality of the designed product. Three-dimensional (3D) printing is one kind of RP that creates three-dimensional objects from CAD models. The paper presents a computer aided process planning system for printing medical products. 3D printing has been used to solve complex medical problems such as surgical instruments, bioengineered products, medical implants, and surgical guides.

  • Teenage girls under the influence of the physical changes due to the rapid physical development and appearance are interested. 200 parts were used for the statistical analysis of this research against the common excitation high school student positioned in Seoul. First, there was lots of the girl student managing the appearance due to the psychological satisfaction. And the girl student without the friend of the opposite sex managed the appearance at the psychological satisfaction. Because to be more important, thing including the studying, and etc. was the priority the girl student who doesn't the appearance management did not do the appearance management. Second, the factor found out over one month allowance 50,000 circle to be the very important factor through the beauty action high of the high beauty product concern degree and girl student action of the beauty product concern degree and girl student where there is the friend of the opposite sex. Third, the more the concern degree about the beauty product was high as the concern degree about the beauty was high, the girl student in high school could know that beauty action was high as the concern degree about the multi function beauty product was high.

  • An automatic grease lubricator provides an adequate amount of fresh grease constantly to any type of rotating machine to minimize friction heat and reduce friction loss. This study seeks to develop an automatic grease lubricator by means of rapid prototyping with a gear-driven mechanism and a controlled operation time. The ultimate design is to lubricate an adequate amount of grease by a simple dip-switch clicking mechanism according to an advanced set cycle. The backlash of the gear was minimized to increase the power, and to increase the power of the mechanism, the binding frequency and the thickness of the coil were changed. To control the rotation cycles of the main shaft according to certain set numbers, different resistances and chips were used in the design of the circuit which controls the electrical signals via a pulse. A digital mock-up was analyzed and the rapid prototyping (RP) trial products were tested with a PCB circuit and grease. An evaluation of the outlet capacity of RP trial products was conducted, as the friction caused by the outlet on the wall surface was an important factor in the operation of the equipment. Finally, a finishing process was applied to decrease the roughness of a surface to a comparable level to test the performance of the product.

  • This study was developed high-quality a large size precast channel structure using polymer concrete to improve quality of the product as well as to enhance construction quality. Precast PC represent the fastest growing segment of the polymer concrete industry. The fast curing, high strength, and low impermeability permit thin section and rapid reuse of moulds. Developed precast channel structure will be structural experiment and analysis. Also, through an example to construct will be develop the most suitable section survey and make practicable.

  • Based on the rapid development of information technology (IT) including networks, manufacturing environment faces more customer engagement, global collaboration, greater emphasis on agility, increasing reach and connectivity through world-wide web, and micro transaction tracking and intelligence to name a few. The new ideas of manufacturing concept, eManufacturing is discussed in view of IT. In specific, a framework to identify. IT application in the product realization process and collaboration and coordination to implement eManufacturing is proposed.

  • Rapid spread of Internet, there appear so many commercial wedsites. Websites are not only tools to advertise a company or a product, but also value-added products inself. So we need a systematic approach(planning, design, implementation) to develop a website. But existing reserches on website development have corvered only technological issues such as network and HCI(Human Computer Intercation). In this research a framework is proposed to develop a website systematically using database of existing websites. This framework is composed of several stages-target customer segmentation, determination of services on website, dtermination of business model, functinal positioning, and evaution.

  • 성공적인 신제품개발과 이에 따른 시장개발을 위해서는 신제품의 새로운 편익에 대해 소비자가 지각하고 있어야 하며, 이러한 편익이 소비자의 욕구를 해결해 줄 수 있어야 한다. 시장에 도입되는 신제품의 편익에 대해 새로운 가치를 부여하는 방법은 매우 다양할 수 있으나 무엇보다 새로운 가치가 소비자의 입장에서 혜택으로 여겨져야만 성공적으로 시장에 정착할 수 있다. 본 연구는 기존에 기술 중심적으로 설명되고 평가되어 왔던 와이브로 서비스를 소비자의 가치체계를 중심으로 서비스속성을 파악하고, 속성에 대한 부분가치를 추정해 이들의 상대적 중요도를 살펴보았다. 또한 부분가치를 기준으로 시장발전단계에 따른 표적고객집단을 선정하고 표적고객의 특징을 규명하는 동시에 적절한 마케팅전략을 제언하고자 한다.

  • Polymorphism has been recognized to be a critical issue throughout the drug product development process. Most of solid phase drugs have polymorphism, which has generated a great deal of interest and the field has been evolving rapidly. Preferably, thermodynamically most stable form of a drug substance is selected to obtain consistent bioavailability over its shelf life and various storage conditions. Moreover, it has the lowest potential for conversion from one polymorphic form to another. However, metastable or amorphous forms may be used intentionally to induce faster dissolution rate for rapid drug absorption and higher efficacy. For pharmaceutical industry, polymorphism is one of the key activities in form selection process together with salt selection. This article introduces the main features in the investigation of solid form selection especially polymorphic behavior with thermodynamic backgrounds, physicochemical properties with solubility, dissolution, and mechanical properties, and characterization techniques for proper analysis. The final form can be recommended based on the physicochemical and biopharmaceutical properties and by the processability, scalability and safety considerations. Pharmaceutical scientists especially in charge of formulation need to be well aware of the above issues to assure product quality.
