Distortional and local buckling are important factors that influences the bearing capacity of steel-concrete composite box-beam. Through theoretical analysis of distortional buckling forms, a stability analysis calculation model of composite box beam considering rotation of steel beam top flange is presented. The critical bending moment calculation formula of distortional buckling is established. In addition, mechanical behaviors of a steel beam web in the negative moment zone subjected separately to bending stress, shear stress and combined stress are investigated. Elastic buckling factors of steel web under different stress conditions are calculated. On the basis of local buckling analysis results, a limiting value for height-to thickness ratio of a steel web in the elastic stage is proposed. Numerical examples are presented to verify the proposed models.

This paper deals with the consideration of mathematical models with regards to growth of cluster and firms by reviewing the Metcalf and Breuner's articles. prior studies have been argued the phenomenon of local industrial clusters and districts. Several concepts have been adopted to support the success of and changes to these clusters and firm growth. Through the review of two papers, evolution of both cluster and firm growth may be achieved in terms of utilizations of the different local aspects and mechanisms. This paper supports the theoretical back bone with regards to the regional cluster policy implementing in Korea for the purpose of regional developments. In particular, a mathematical model that, on a more abstract level, captures the fundamental dynamic structure of all the observed mechanisms. On the basis of this model, the emergence and evolution of local clusters can be described. Also this model has given that the knowledge sharing between firms has an important role to firms and cluster' growth.

This paper examined the present status of local newspapers and their problems. It was originated from the fact that the number of local newspapers have continuously increased since 1987 when the establishment of newspaper company became convenient, and that as a result the competition among local newspapers became high and several unexpected negative out comes brought forth. The analytical focus of this parer was placed on the internal and external environments surroundings local newspapers. The results showed followings: There are too many local newspapers competing each other in the same area; Financial crises mainly caused by over-competition are critical; Ownership and business operations are too distorted to take the socially expected role of newspapers; Many newspapers are often mobilized for the political and economic purposes of the owner; Market rules and advertising inducement practices are likely to be violated because of over-competition; the morales of Journalists are decreased and work qualities are deteriorated. On the basis of these findings this paper suggested several policy implications: The structure of ownership has to be changed into a direction where a few major stock-holders cannot influence the whole business operations; Top managers have to change their business motivation from profit-seeking to profit-sharing; business practices has to be open and clean; New editorial polices attracting readers have to be established; qualified Journalists have to be recruited and they have to be retrained throughout their career life.

This study was performed to study the efficiency of a local ventilation system, installed in dental laboratories, and of two types of protecting face masks. The dust originating from the workpiece as well as from the wheels and stones was collected on air filters in the cutting cycle during coarse and fine grinding, and in the subsequent polishing procedures of each specific dental material. The efficiency of the ventilation system was measured on the basis of weight reduction of dust in the breathing air at a distance about 20-40 cm from workpiece. The results were as follows: 1. Use of the local ventilation system reduced the amounts of respirable dust to an average level of 21.4%, although the efficiency of the local ventilation system varied depending upon materials used. 2. Mounting a nozzle on the tube improved the efficiency of the ventilation system considerably. The efficiency of the local ventilation system also increased as the workpiece was closing to the tube inlet. 3. With or without the local ventilation system, the distance between the position of the workpiece and sampler greatly affected the dust level. 4. The face masks covering the sampler improved the efficiency of the ventilation system considerably.

Damage detection is a challenging, complex, and at the same time very important research topic in civil engineering. Identifying the location and severity of damage in a structure, as well as the global effects of local damage on the performance of the structure are fundamental elements of damage detection algorithms. Local damage detection is essential for structural health monitoring since local damages can propagate and become detrimental to the functionality of the entire structure. Existing studies present several methods which utilize sensor data, and track global changes in the structure. The challenging issue for these methods is to be sensitive enough in identifYing local damage. Autoregressive models with exogenous terms (ARX) are a popular class of modeling approaches which are the basis for a large group of local damage detection algorithms. This study presents an algorithm, called Influence-based Damage Detection Algorithm (IDDA), which is developed for identification of local damage based on regression of the vibration responses. The formulation of the algorithm and the post-processing statistical framework is presented and its performance is validated through implementation on an experimental beam-column connection which is instrumented by dense-clustered wired and wireless sensor networks. While implementing the algorithm, two different sensor networks with different sensing qualities are utilized and the results are compared. Based on the comparison of the results, the effect of sensor noise on the performance of the proposed algorithm is observed and discussed in this paper.

본 논문에서는 농담구조소(濃淡構造素)(GSE, grayscale structuring element)를 갖는 형태학 필터의 실시간 처리를 위한 알고리즘을 제안하였다. 제안된 알고리즘에서는 GSE로부터 유도된 basis matrix와 입력 샘플들로 구성된 input matrix를 이용하여 각 형태학 연산들을 소역행렬연산(local matrix operation)으로 새롭게 정의하고 있는데, 이를 이용하여 opening이나 closing과 같은 복합 형태학 연산들을 실시간으로 처리할 수 있음을 보였다. 제안된 알고리즘은 복원 형태학 연산들을 erosion과 dilation의 직렬조합(cascade combination)으로 처리하던 기존의 방법에 비해 적은 메모리를 필요로 하면서도, 출력을 얻기까지의 지연(遲延)(delay)이 훨씬 적다는 장점을 갖는다. 또한 본 논문에서는 형태학 필터를 VLSI로 구현하기 위한 효율적 방안을 제안하였다. 제안된 방법에서는 p-bit으로 표현되는 신호에 대한 형태학 연산을 p개의 이진(binary) 형태학 연산자들의 조합으로 구현하였는데, 각 이진 연산자들은 MSB(most significant bit)부터 순차적으로 (bit-serial approach) 해당 레벨의 bit들을 처리하여 출력을 부를 구조로 이루어져 있다. 본 논문에서는 형태학 필터의 VLSI 구현에 있어서 제안된 방법이 기존의 Threshold Decomposition 방법 등에 비해 보다 효율적이라는 것을 보였다.
