A method to reduce seam line artifact in spatial compounding of ultrasonic images is presented. Spatial compounding is a speckle reducing imaging technique in which a number of ultrasound images of a given target that have been obtained from multiple view angles are combined into a single compounded image by combining the data received from each data point in the compounded image. Since different view angle results in different view area, and the images of different view arms are combined into an image, the compounded image consists of regions with different signal to noise ratio, and the boundary lines between these regions are visible as seam lines in the compounded images. In this paper, we present an algorithm that reduces the visibility of this seam line in the spatially compounded images. Design procedure for a FIH filter is described and the results of applying the filter to in-vivo ultrasonic images are analyzed.

As a faithful study about the intended plan of builder, this article studied the Dosanseodang(陶山書堂) which is located in the Dosanseodang(陶山書堂). The Dosanseowon is one of the representative Yi-Dynasty' Seowons. Through the review of $\ulcorner$The Writings of Toegye$\lrcorner$. It is found several intended plan of the Dosanseodang(陶山書 堂) as follows. 1. When Toegye located the site of the Dosanseodang in the Dosan, using four criteria such as 1) geographical characteristics(地 理), 2) hills and waters(山水) 3) form and orientation of valley, 4) so-cial characteristics. 2. In the Dosan area, the location of Seodang was determined by the physical characteristics of the valley(orientation and entrance), not by the concept of Fung-sui(風水). 3. The whole spatial structure of Seodang area formed triangle, and the Dosanseodang was located at the angular point of the triangle. 4. The landscape elements of the Dosanseodang falled into the three landscape hierarchy such as a front view, a middle view, and a distance view. Besides the three views, there was a borrowed view which Toegye defined in terms of ownership.

The purpose of this study was to classify the somatotype of elderly women and to extract discriminant factors of the classification. The subjects were 218 elderly women aged 60-85 years old. Data were collected from 46 anthropometric and photographic measurements of each subject and analyzed by frequencies, crosstabs, analysis of variance and discriminant analysis. The somatotype was classified into 5 types according to the lateral view. The normal type was defined as the type which the plumb line passes through the cervicale and the lateral malleolus. The lean-back type positioned the plumb line more posteriorly than normal type. The swayback type positioned the plumb line at about the same line as the lean-back type, but curvature of lateral view was prominent. The lean-forward type I and II positioned the plumb line more anteriorly than normal, but the spinal curvature of the type II disappeared. As the result of discriminant analysis, significant discriminant factors of anthropometric measurement were cervicale height, anterior waist height, neck point to posterior waist length, anterior waist length. Photographic measurement were C valve, D value, ∠${\alpha}$ and ∠${\beta}$.

A flow control system was designed and fabricated to control the flow rate of liquid through the pipe. This control system was composed of hardwares and software, hardwares as controller, gate valve, orifice meter and data aquisition board and software as National instruments Labview program. Control of flow rate was executed by adjusting the pneumatic valve located at the center of pipe line based on the control signal generated by LabView PID control algorithm, which converts analog signal measured by pressure difference of orifice to digital signal to adjust pneumatic valve. For the controller setup Ziegler-Nichols tuning technique was applied and control performances were investigated for not only the disturbance but also the set point changes. Developed system showed good control performances in flow control enough to use as teaching tool of feedback control theory and practice in university, and also as industrial application.

In this paper, we propose a 3D view design scheme which arranges 2D information in a 3D virtual space with a flexible interface and voice information. The scheme allows the user interface of the 2D image in 3D virtual space anytime from any view point. Voice information can be easily attached. It is this simple and efficient image and voice information arrangement in 3D virtual space that improves information transfer.

This paper considers the following case: (1) the product is paid by the right price for a lot accepted by a given consumer's acceptance sampling plan, and (2) the product is paid by the discounted price for a lot rejected by this plan. In such a case, the producer's sampling plan need not be the same as that of the consumer's. From the producer's view point, the producer need to determine the preliminary sample size which maximizes his revenue. This paper, therefore, determines an optimal preliminary sample size from the producer's view point. This preliminary sample size is affected by the consumer's acceptance sampling plan, percent defective, preliminary inspection cost and the discount rate of the price.

There are many types of linguistical system generally being used in modern society and it is essential to understand the primary components comprising the linguistical system when communication by the language system. In the linguistics point of view, the sign system has been developed from the simple linguistic symbols used by our ancestors in the ancient period, those visual linguistic sign can be so symbolize and express simply the significant meaning of it that people can understand and communicate with it so fast and easily. Therefore, the purpose of this report is how the sign system can be convenient, handy, safe, comfortable, and confusion-proof to the occupants as the public media; easily understandable to the individual by the development and constitution of effectual signage system concerning guidance, direction and safeguards in thee visual linguistics point of view. Consequently, the sign system have been studied based upon the theory of visual perception considering the cognitive and sociopsychological affects of user.

The objectives of this study were to study multicultural society of rural areas in Korea. USA immigration law permits permanent settlement but Korea immigration law prohibits permanent settlement. USA adopted the territorial principle but Korea adopted the personal(nationality) principle. So a large number of people immigrated and settled in USA and mass(collective) immigrants is usual in USA. But foreign workers(temporary immigration) and international marriage women(individual immigrants) is usual in Korea. According to the positive law, foreign workers cannot settle down in Korea. So international marriage women immigrants are main cause of multicultural society in rural areas in Korea. This is the particularity of multicultural society in rural areas in Korea. So it is necessary to differentiate multicultural society policy according to areas and residents. Many peoples see multicultural society from a point of view of human rights and welfare. But it is also necessary to see multicultural society from a point of view of economic and policy.

Workplace knowledge sharing is a complex process and there are a large number of studies in the area. In this article three theoretical approaches in library and information science are used to discuss knowledge sharing in the workplace. The approaches are information behavior, social capital, and information culture, and they bring important insights that need to be considered from a holistic management point of view when it comes to knowledge sharing. The individual's relation to different levels of context is important, meaning both in relation to work roles, work tasks, situations, organizational structures, and culture. The frameworks also shed light on where and how knowledge sharing activities are present in the organization. From a knowledge management point of view, it is important to acknowledge that when knowledge is valued, there is also an awareness of the knowledge sharing activities. Also, in addition to more traditional views of context, the frameworks bring forward different views on context, such as time and space as contextual factors.
