일반적으로 탑재 교정을 위한 교정 반사경 구동장치는 교정임무 수행 시에는 주광경로 상의 전개위치로 반사경을 구동하며, 교정 후에는 주광경로와 이격된 수납위치로 반사경을 구동한다. 교정 반사경 구동장치의 결함 발생 시에는 반사경이 전개된 상태로 남아 주광경로를 차단하지 않도록 반사경을 강제 수납한다. 본 논문에서 제안한 결함 안전장치를 가지는 교정용 반사경 구동장치는 구동을 위한 스텝모터, 전개 및 수납 상태확인을 위한 마이크로 스위치, 베어링과 스프링의 기능을 동시에 갖는 피봇베어링 등으로 구성된다. 본 논문에서는 상기의 기능을 갖는 교정 반사경 구동장치 구현을 위한 구동장치 구성을 제안하였으며, 구성요소의 최적화 설계치를 도출하고 기능시험을 통해 결함안전 기능을 갖는 교정 반사경 구동장치의 유효성을 검증하였다.

The purpose of this study is to develop kitchen furniture design for 40-pyung apartment Houses based on stored item of Cooking, Eating and Utility Area. The research data is gotten at a field study of stored items of Cooking, Eating and Utility Area and depth interview. The results of this study were as follows; 1)The kitchen furniture the preparation unit and the sink, the kitchen table, the heating unit and the service table, arranged at the tall storage. 2)The total bulk considered and holding volume ($2.7m^3$) with ground clearance (40%) planned with about $4.21m^3$. 3)Assumed at height and 162cm did a lower part height with 860mm and the upper depth 340mm, did with 700mm where raises. the storage the ceiling which raises will select and considered and with 2200mm did. 4)Arrangement of the kitchen the kitchen form which is an open type (L/DK or L.D.K) arranged many in forms of letter.

Housing construction companies have been providing master bedroom walk-in closet as a selling point in modest sized apartments as small as 74m$^2$. It is noticeable that master bedroom walk-in closet in apartments provided by public sectors showed much variety in its size. This study tries to set up the guide line of master bedroom walk-in closet size. It is quite reasonable to assume that the biggest space-occupiers in walk-in closet are blankets and clothing. The survey conducted in this study shows that the number of clothes people keep in their closet does not show any significant difference regardless of square footage of their apartments. 34.7% of respondent answered they keep about 50-60 clothes using coat hangers, where 20-30 of those are winter clothes. It is calculated the required optimum length of the walk-in closet is 3.8m$^2$. Considering the most popular longitudinal dimension of master bedroom, 3.9m, and the space needed to accommodate blankets, it can be concluded that the required length of storage in master bedroom walk-in closet is 2.1m. The length can be adjusted reflecting the length of the master bedroom.

This research is to suggest effective kitchen furniture design for 40, 50 pyeong-size apartment considering the quantity and volume, heights or length of stored items for cooking. The research candidates are purposive-sampled 30 households in Kangnam, Seoul. The observation shows that the volume of kitchen furniture is $3.1{\sim}5.9m^3$ and of utility furniture is $0.3{\sim}3.8m^3$. For each households hold average of 886 kitchenwares, $4.1m^3$. Such were normally stored in the upper and lower storage and tall storage closet for a kitchen. Through the field studies and depth interviews, it is shown that there are 287 (33.2%), $1.67m^3$ of the application for preparing food, certain knives, disposable products and food which is considered absolutely or comparatively hard to organize. Products that are very hard to organize are the small application for cooking, grouped kitchenware such as openers, the applications with long rod shape food, and detergent. There are 96 of such products, taking the volume of $0.32m^3$; thus, such products are considered to improve the kitchen furniture design. And the shelf of storage can the control 3cm hights according to result of this research.

This study aimed to fine out the rational quantity of kitchen utensils and appliances Questionnair was distributed to families of 469 of middle school students. I studied status of kitchen work centers, quantity and the kinds of kitchen utensils. The results were as follows. 1. the status of kitchen :1) The percentage of western style work centers was significantly higher than the average level of Seoul. 2) The length and the height of work centers were below standard. 3) Arrangement of work centers was relatively correct, however, the kinds of kitchen work centers were not fully equipped. 2. The quantity of kitchen utensils: The socio-economic status were the main factor of the quantity of kitchen utensils. Educational level, income level and floor space were strongly corrected to the quantity of kitchen utensils.

지금까지 많은 필기 숫자 인식 방법들이 제안되었지만 고도의 신뢰도가 요구되는 은행 수납 장표상의 숫자 인식에 적합한 방법은 아직 발표된 것이 미미한 실정이다. 본 연구에서는 세 개의 분류기의 결과를 융합하여 100%에 가까운 신뢰도를 낼 수 있는 필기숫자 인식 시스템을 제안하였다. Karhunen-Loeve Transform(KLT)를 통하여 특징을 추출하였으며 오류 역전파 신경망(BP), LVQ를 적용한 SOFM(SOFM-LVQ)과 Weignted Several Nearest Neighbor(WSNN)을 분류기로 사용하였다. 융합을 위해서는 다수결(Majority Voting)이 아닌 만장일치제(Unanimous Voting)을 적용하여 신뢰도를 높혔다. ETL-6 DB를 사용하여 실험하였으며 실험 결과 99.95%의 높은 신뢰도를 기록하였다.

An automated mechanical parking system with a dedicated multi-floor building has been studied for improvements. Among the major components of the system, study is focused on the trolly which is the most important to the overall reliability of the system. The trolley holds and moves a parked vehicle horizontally into a specified position for the next sequence of operations. Optimization of a trolly structure is presented for strength and simplicity. With optimization, the weight has been reduced by 30% with respect to the conventional design.

Present work deals with a study on the deployment or retraction of cantilever beam that includes the rigid-body motion of large displacement of beam through the translational and rotational motions in 2-dimensional plane. The equations of motion are derived with respect to non-Cartesian coordinate system. In the formulation of equations of motion, shear deformations and geometrically non-linear effect are included. An assumed mode method is applied and numerical convergence characteristics are studied also. Types of motion of the moving beam are assumed to be classified as‘slow’or‘fast’motion, and the dynamic characteristics are investigated.
