Human body structure can be considered as a complex of many elements such as head, chest, arm, leg and etc. As the correct classification of human body is basic for the design of all the materials used by mankind and since we cannot consider all the elements simultaneously, there is a need of extracting a Sew elements which can be "most" representative of all those elements. This paper describes the procedure of determining those representative body dimensions utilizing the data obtained from a national project carried out in 1976. Also the relationship of the above determined body dimensions to the other commonly reference body dimensions are given in linear forms.ear forms.

The hot spot stress approach and the notch strain approach are discussed with some results of them. And a stress model that can be applicable to several types of weld joints with single S-N curve of the base material. The stress model uses the geometric characteristics of the stress distribution vicinity of weld joints. The model was applied to five different weld joins(the base material is SM490B). By the representative stress, the experimental fatigue data are plotted very closely to the S-N curve of the base material.

I provide an overview of the application of hydroacoustic methods in South Korea to understand the current research status in relation to fisheries acoustics and to determine which areas require further study. One main purpose for using a scientific echosounder, a representative tool using the hydroacoustic method, is to evaluate the abundance of fisheries resources. Thus, two representative methods for abundance estimation are described. The history of fisheries acoustics worldwide is also summarized.

This paper introduces attempts to obtain the'representative'characteristics of the apparent mass and mechanical impedance of seated Korean subjects under vertical vibration. Individual responses of the apparent mass and driving-point mechanical impedance obtained from forty-one Korean subjects are illustrated. Four kinds of vibration levels and three different sitting postures are selected to collect the responses of each subject. Those individual responses are used to estimate the 'mean' mechanical impedance, which may be expected to be a representative model to Korean subjects. Several interesting features of the estimated mechanical impedance are suggested and compared to those of ISO 5982.

In this study, the basic operational plan for Chungnam Representative Library was established to define the function, roles, and operating strategies of the Chungnam Representing Library. A perception survey was conducted among public library users in Chungcheongnam-do and visitors to the provincial government building. Based from the results, Chungnam Representing Library's roles in collection, organization, preservation, and provision of comprehensive library resources in the city and province was shown to be the highest at 25.65%. Moreover, when respondents were asked about their preferred data resource type for collection and management of the Chungnam Representing Library, printed data emerged as the most preferred with an average of 3.96. Depending on the theme, literature was the most preferred, resulting to an average of 4.27. Lastly, when respondents were asked about the type of service that they expect from Chungnam Representing Library, a library that provides good books from various areas and knowledge information was the most demanded at 27.79%.

The physical components of a river, such as water surface width/river width ratio, water level, and flow velocity vary according to different flowrates. Moreover, the riverside landscapes are greatly affected by the change of physical components of the stream or river. This paper provides an analysis of the influence of changing physical components of a river on the riverside landscape using a survey-based quantification method. The questionnaire was developed based on current literature, and was submitted to 326 people who each visited a representative station along the riverside.This survey was implemented three times at each representative station during periods of different flowrates. The results of this analysis and survey have Produced an understanding of the relationship between the variation of physical components and riverside landscapes. Survey results about the flow comparison are summarized as follows. Viewing riverside landscapes, most respondents are sensitive to the change of the flow velocity and prefer high water levels to low water levels. As a whole, respondents prefer abundant stream flows and moderate flow velocity in which they can perceive the flow of water. The minimum instream flows for riverside landscapes is estimated at each representative station by using a survey-based quantification method, and the estimated results of some representative stations were greater than the mean monthly flow at each station. The result of this analysis shows that establishing minimum instream flows for riverside landscapes is not only a technical problem, but also a legal problem. Therefore, in the to establish the instream flows in a river, the estimated results have to be considered as a relative standard. Regarding the survey results, respondents' satisfaction level didn't show any clear inclination according to the variation of various hydraulic properties. In determining the minimum instream flow using such an inquiry method, the structure of riverside scenery may vary according to the change of seasons or months. Therefore, to determine a consistent general inclination about the flow rate, it is necessary to have more detailed flow rates for each season or month combined with more inquiries.

In some previous works on musical genre classification, human experts specify segments of a song for extracting musical features. Although this approach might contribute to performance enhancement, it requires manual intervention and thus can not be easily applied to new incoming songs. To extract musical features without the manual intervention, most of recent researches on music genre classification extract features from a pre-determined part of a song (for example, 30 seconds after initial 30 seconds), which may cause loss of accuracy. In this paper, in order to alleviate the accuracy problem, we propose a new method, which extracts features from representative segments (or main theme part) identified by structure analysis of music piece. The proposed method detects segments with repeated melody in a song and selects representative ones among them by considering their positions and energies. Experimental results show that the proposed method significantly improve the accuracy compared to the approach using a pre-determined part.
