현대사회는 비교적 완벽한 소방기구를 통해 화재의 예방과 진압을 하고 있지만, 고대에는 신앙이나 금기 또는 민간조직에 의지하여 이러한 사회적 직능을 수행하였다. 여기서는 중국 절강성(浙江省) 동부 금화(金華)지역의 전통 소방풍속에 대해 몇 가지 간단히 소개하고자 한다.

Body measurement was first made with the subjects of 193 males in their 20s residing in the Ningbo area, Zhejiang Province in China. In this first report, lower body shapes were classified and discriminated by using anthropometric measurement indices and lower body analysis. The following sums up the research: 1. Compared with the average values of Korean males in their 20s, the Chinese subjects were characterized with thinner waist, more flat hip, and smaller midthigh. 2. The subjects of Chinese males in their 20s showed three types of lower bodies: H-Round Type (25.91%)-thick waist-abdomen, round cross-section waist-abdomen, and small waist-hip difference. A-Trapezoid Type (34.72%)-small width of omphalion waist-abdomen, average cross-section waist-abdomen, and large waist-hip difference. A-Balance Type (39.38%)-average width of omphalion waist-abdomen, flat cross-section waist-abdomen, and large waist-hip difference. 3. Seven useful variables for the categorization of the subjects' lower body types were chosen through stepwise discriminant analysis, and the hit ratio of discrimination was 96.89%.

Body measurement was held for the subjects of Chinese adult males in their 20s through 40s residing in the Ningbo area of Zhejiang Province in order to provide body type information and raise the fit of clothing products for the advancement into the Chinese market. The following sums up the analysis of body types based on body measurement: 1. Seven factors to compose body types were produced from the analysis of males in their 20s, explaining 76.07% of variables and representing 3 types according to cluster analysis. Type 1 was H-b and appeared as much as 32.14%. Type 2, semi X-d, was 40.81%, while Type 3, A-i, had 27.04%. 2. Eight body type composing factors were extracted from the analysis of men in their 30s and 40s. The factors explained 76.77% of all the variables and represented 4 types according to cluster analysis. Type 1, H-d, had the appearance rate of 18.47%; Type 2, H-b, 40.84%; Type 3, Y-i, 27.71%; and Type 4, semi X-s, 11.95%.

본 논문에서는 보다 효율적인 영상 처리를 위해 생물 시각 시스템의 특성을 반영하는 영상 표현 방법을 제안한다. 기존의 방법들이 단순화된 특성들만을 이용한 것인데 비해 본 논문에서 제안하는 방법은 고등 생물의 시각이 독립된 처리 경로를 가진 다는 점에 기반을 두고 있으며, 각 처리 경로의 시작이 되는 두 가지의 신경절 세포가 가지는 수용장의 분포 및 크기의 특성을 독립적으로 고려하여 각각 인식 및 움직임 정보 처리에 효율적인 영상 표현을 얻어낸다. 제안된 방법에 대한 실험 및 분석을 통하여 본 방법이 영상의 데이터를 효율적으로 축약시켜줄 수 있음을 알 수 있다.

"Haerincheokso" is a collection of 279 letters, including the last one Gong Heon-gyeong sent to Lee Sang-jeok in 1865, which were sent by 61 people from 1830. This study examined the career and activities of each of the 61 senders based on their personal details. First, it was found that the senders had special relationships with Lee Sang-jeok. One of them, for example, published "Eunsongdangjip", a collection of poems written by Lee Sang-jeok. Second, many of the senders were from Jiansu Province, Shanxi Province and Zhejiang Province. Third, more than 50 percent of people Lee Sang-jeok had a friendship with were outstanding intellectuals who were Jinsa or Geoin. Fourth, all of the senders except for a monk and the owner of a ginseng shop did vigorous cultural activities in Yanjing at the time. If the reader read "Haerincheokso" based on information above, he will be able to reduce mistakes of misreading the book. Furthermore, the book offers some materials necessary to grasp the cultural exchanges between Korea and China in the 19th century.

Case of patients with weakness in cardiopulmonary system, other ambulatory function is normal, but oxygen supply function is problem. So they need reduce energy consumption for gait by assistance system. In this study, we designed and developed walking assistant device which helps flexion and extension of hip joint for cardiopulmonary patients. There are two motors, each at the left and right side of pelvis, providing torque to the hip joint. The target angle of the flexion and extension in the hip joint is set according to the normal gait. As a result, reduction of energy consumption was 14.8% by gait assistive device.

Inference process of resolution-based automated reasoning easily consumes the memory of computer without giving any useful result by priducing lots of fruioless information which are not necessary for the conslusion. This paper suggests a control strategy for saving the space of computer memory and reducing the inference time. The strategy uses a restriction that comparatively irrelevant axioms do mot take pare in the resoluition. In order to analyze and determine the priorities of the input axioms of joning the inference process, the system employs the fuzzy relational products.

An effective stiffness, analogous to that of a wound spring, can be created by antagonistic redundant actuation of general closed-chain mechanisms. The qualitative and quantitative characteristics of the effective stiffness are investigated through a Four-bar mechanism, and a load distribution method is introduced which simultaneously guarantees the required system motion and the effective stiffness of the Four-bar mechanism. Furthermore, a simulation is performed to understand the inter-relationship among the effective stiffness, the Four-bar geometry, and the actuation effort. Based on this analysis, the Four-bar synthesis problem for effective stiffness generation is discussed.
