  • Design structure of a mobile phone has been changed to a converged style, which has so many functions. However, the converged mobile phone could not satisfy the users who want to use only specific functions, so with Axiomatic Design, we have studied for making a proposal to set up the new concept. The goal of this study is to derive a general solution with Axiomatic Design to verify the Independence. By enhancing the existing design model and differentiating the function of mobile phone, user will be able to choose desirable products, which have only specific functions and/or specific parts. First of all, we checked the Independence about the existing design model. Then, we developed the new design model with the idea that base mobile phone should have basic functions and additional functions can be separated, surely be connected when users want.

  • Recent technologic innovations have created possibilities for restorative dentistry, such as computer-aided design and computer-aided manufacturing. This article presents a CAD process that has been developed for the fabrication of dental restorations. This process uses a 4-axes driving mechanism and an improved optical displacement sensor, successfully applied in other industries. In optical displacement sensor, the light beam emitted from the LED is converged through the light source lenses and thrown on the object to be detected. When the light beam is reflected from the object, however, it is diffused. The diffused light beam is converged again by the receiver lenses and cast on the optical position detector element as a small spot.

  • Ultimately, this research will focus on the activity traits of future customers in the convergence age. To accomplish that, firstly, researcher develop measures for assessing the convergence level of digital devices and digital services. Next, this will investigate the behavioral traits of people who use specific devices or services on the internet or mobile networks. This study proposed five convergence measures each for devices and services. For digital devices, measures such as converged functions, accessibility to network, portability, immediate communicability, and expandibility of functions were utilized. For digital measures such as scope of users, newness, social network level, ease-of use on mobile networks, and expandibility of information were used. We believe that the research results can provide insights for those wishing to explore the convergence level of devices and services and those developing high-level converged devices and digital services.

  • Considering the rapid growth of elderly population and the increase of medical demand for aged, many of geriatric hospitals are needed in Korea. On the other hand, supplies of hospitals for acute care are considered to be excessive. So many of small and medium hospitals facing management problems have been converged to geriatric hospitals. These attempts are considered resonable for efficient utilization of health care resources in Korea. This paper aims to identify the concept of geriatric hospital and to analyze the problems and then to seek the alternatives for architectural planning on the basis of surveying the geriatric hospitals converged from hospitals for acute care.

  • 최근 디지털 정보기술의 급격한 발전으로 네트워크, 서비스, 단말이 융합되는 BcN 사회로 진화하고 있다. 이에 따라 새로운 융합 서비스 개발을 용이하게 하는 open API 기술에 대한 필요성이 대두되어 왔다. 통신망 사업자의 자원을 서비스 제공자에게 open API를 통하여 개방하면, 서비스 개발자들은 네트워크 프로토콜에 대한 지식이 없어도 open API를 호출하여 복잡하고 다양한 서비스를 쉽게 개발할 수 있다. 본 논문에서는 이동 가입자의 위치주소를 제공하는 Geocoding 기능을 open API로 정의하고, 이를 응용한 Family Finder on TV 서비스에 대해 살펴본다.

  • Solution-state structure of native F430 was determined by using NMR methods and NMR-based distance geometry (DG) computations. Structures were generated with loose NOE-derived interproton distance restraints (2.0-2.5 Å, 2.0-3.5 Å and 2.0-4.5 Å for strong, medium, and weak NOE cross-peak intensities, respectively). 2D NOESY back-calculations of structures were subsequently carried out for establishing the consistence between experimental data and DG-model structures. The back-calculated 2D NOESY spectra of resulting DG structures were well consistent with experimental 2D NOESY spectra. Superposition of 20 independent structures with macrocyclic ring atoms and all atoms of F430 afforded pairwise root mean square deviations (RMSD) of 0.025-0.125 Å and 0.64-1.3 Å, respectively. The macrocyclic rings of structures are well converged to a unique conformation with saddle-shaped deformation whereas most of side chains are not converged. The average dihedral angle (N1-N2-N3-N4, 27.78±1.50°) of 20 DG-structures exhibits that the macrocyclic ring conformation is puckered as much as 12,13-diepimeric F430 (28.75±4.07°).

  • 독일의 Industry4.0에서 출발한 ICT 융합 스마트공장은 4차 산업혁명의 견인차가 되어왔고 주요 국가의 제조업 혁신의 중심에 서 있다. 또한 국가 별 산업 특성에 맞는 방식으로 발전해 나가고 있다. 한국의 경우 경쟁국 대비 뒤늦은 출발로 인해 정부는 빠른 시간 내에 중소 중견업체 중심으로 스마트공장 확산을 위해 정책 수립 및 각종 지원을 하고 있다. 스마트공장의 국제 경쟁력 확보를 위해서는 중소 중견업체에 대한 획일적인 지원보다는 유사 제조업종별 카테고리화 및 디지털 기반의 생산정보 공유가 필요하다. 또한 대기업도 개별적인 스마트공장 확충보다는 중소 중견기업과 함께 동종 산업 간 클라우드 기반의 생산 예측 시스템 구축 및 공유를 통한 스마트공장 협력기반 마련에 동참하여야 제조 산업의 동반 발전을 이룰 수 있다.

  • 본 연구는 시력교정용 안경렌즈의 재질에 따른 자외선 차단 성능을 확인하고자 하였다. 안경렌즈 Acryl, CR-39, NK-55, MR-8 재질의 렌즈에 대하여 흠집 방지와 반사방지 코팅을 한 렌즈 Group A와 여기에 자외선 차단 코팅을 추가한 렌즈 Group B, 그리고 자외선 차단 전용렌즈 Group C에 대하여 자외선 투과율을 측정하였다. 그 결과, UV-A 파장에서 Group A는 CR-39 렌즈가 7.726 %, NK-55 렌즈, 0.043 %, MR-8과 Acryl 렌즈, 0.007 % 순 이었으며 Group B는 CR-39 렌즈가 0.038 %, NK-55 렌즈, 0.037 %, MR-8과 Acryl 렌즈, 0.007 % 순으로 나타나 CR-39 렌즈의 자외선 차단 성능이 크게 개선되었다. Group C는 굴절률이 1.60과 1.67에서 각각 0.005 %, 0.004 %로 나타나 자외선 차단 성능이 가장 우수하였다. 저 도수의 렌즈와 썬글라스의 경우, CR-39 렌즈를 가장 많이 사용하는 현실에서 자외선 차단을 위한 새로운 재질 또는 자외선 흡수제, 자외선 차단코팅 기술 등의 융 복합적 기술개발이 요구된다고 하겠다.

  • Recently, research on precise parts required in aerospace, ship, and automobile industries has been actively conducted. In this paper, electron beam drilling machining parameters were selected and experiments were conducted to compare processing characteristics analysis according to machining parameters through machining experiments of a vaporization amplification sheet to which STS 304 was applied. Also, as a result of measuring the machining. As the thickness gradually increased, it was confirmed that the electron beam could not reach the vaporization amplification sheet and thus melted on the surface of the material. As a result of the experimental analysis, it was analyzed that the vaporization explosion reaction of the vaporization amplification sheet was not normally performed due to the working distance (WD) according to the material thickness.
