This study was purposed to observe the advantages obtained from iridodiagnostics and automatic iridoscope or oriental medical doctors. In order to study the iridodiagnostics, 5 case-researches were made as the first step. The results were obtained as follows. 1. First of all, the formation of darkening area must be paid attentionally with toxic spot and lacunain relation to the interpretation of present illness. 2. The theoretical concepts about structure in iridodiagnostics and oriental medicine were same. 3. The constitutional type of iridodiagnostics played a important role in concluding the nature and background of symptoms. 4. Most of iris signs reflected the histological changes of body structure equally, and successive study about the difference of visceral scheme between iridology and Oriental Medicine would be needed in the future.

I Study on the security measures of the World Cup Korea and Japan jointly in 2002. The paper, purporting to consider security counterplans, comprise five chapters. Chapter I which sets out purpose, scope and method, is followed by chapter II, dealing largely with the legislations and importance on the security measures of the 17th FIFA World Cup in 2002. Chapter III concerns the security environment -internal environment, external environment- and the highlights accidents and events of history on the FIFA World Cup. Chapter IV consider security measures of the World Cup Korea in 2002. It is followed by concluding observation made in chapter V. To be operated security systems effectively, these need to be regulated according to a security measures organizations, security facilities and equipments, security plan and protective force, security operations and so forth.

As a result of rapid advances in communication technology, fiber optics have begun to be adopted in most telecommunication systems 3s an economic choice Due to the trend of evolution toward broadband communication network with fiber optics and electronic devices. the network design problem for broadband communication has been received a great deal of research attention recently. In this paper, we address a topological design problem for broadband local access network with uncertain demands, which has received surprisingly little attention so far. in our problem, we select a set of hubs and links for constructing network expected penalty cost for the amount of undersupplied In addition to the usual cost terms of the fixed demand problem Our problem can be approximated as a mixed 0-1 integer programming problem by using Szwarc’s linear approximation technique. Then the problem is transformed successfully into a version of classical network design model. Some computational experiments for the model and concluding remarks are described.

A laboratory experiment was conducted to investigate the effects of working posture. work/rest ration, and task type on the physical workload in automobile assembly jobs. Ten healthy male university students participated as subjects in the experiment. East subject performed 18 experimental session with combination of 3 working posture 3 work/rest ratio and 2 task types. To examine the effect of various working conditions on workload, DMG analysis was performed on 4 different muscles in the neck an arm area, Also RPE scale and heart rate were taken as response variables. The result showed that all working conditions considered in the experiment had significant effects on the workload concluding that labor intensity in auto assembly jobs should be adjusted with respect to different levels of working posture, work/rest ratio, and task type. Detailed analysis are presented in the paper.

This paper describes a digital signature-based method for original and updated video authentication. The method uses multiple digital signatures in dealing with video data undergoing multiple change/updating. In addition, a feature based on neighbouring block similarity measure is applied to deal with certain image/video modification. The proposed method can cope with wide range of image/video tampering. It is suitable for practical use of video data, where updating may be performed by more than one legal parties. Experimental results are included with concluding remarks.

In this paper, we investigate the effect of the retransmission limit both the system capacity and the average number of retransmissions in a voice/data DS-CDMA system. Basically, we consider the IS-95 type reverse link of the CDMA system, which supports two kinds of services: a general voice and a packetized data service. ARQ is used for the reliable data transmission. Convolutional code is used for FEC and CRC-CCITT code is used for the error detection in ARQ. The result shows that the number of concurrent data users decreases as we reduce the number of the retransmissions. However, at the same time, we can also reduce the average number of retransmissions. Concluding1y, we can select the retransmission limit so as to reduce large amount of' retransmissions with small sacrifice in the system capacity.

In order to understand the characteristics of the Japanese conception of space, we examined the characteristics of Japanese human geography, schools of thought, and aesthetics through the examinations on relevant documents. In addition, we reorganized such cultural backgrounds in relation to the Japanese perception of space, extracting the fundamental principles and elements of Japanese space composition and examining their significance. We propose a structural framework for understanding and analyzing Japanese space based on the reciprocal relationship and meaning among the various elements of Japanese space. Using this analytical framework, we studied the representative works of Japanese interior space, concluding in an analysis of the expressive characteristics of the Japanese notion of space.

Flexible structures may experience excessive levels of vibration under the action of wind, adversely affecting serviceability and occupant comfort. To ensure the functional performance of a structure, various design modifications are possible, ranging from alternative structural systems to the utilization of passive and active control devices. This paper presents an overview of state-of-the-art measures that reduce the structural response of buildings, including a summary of recent work in aerodynamic tailoring and a discussion of auxiliary damping devices for mitigating the wind-induced motion of structures. In addition, some discussion of the application of such devices to improve structural resistance to seismic events is also presented, concluding with detailed examples of the application of auxiliary damping devices in Australia, Canada, China, Japan, and the United States.

South Korea and Mongolia are both the member countries of the World Trade Organization, but neither was the country with FTA. Nowadays, South Korea widely concludes the FTA with other countries, and the trade area has extended toward the neighboring continents and seas. Mongolia is a country with smallest economic entity but large in area and with abundant underground resources. And it's a main strategic zone of Eurasia. After the disintegration of the Soviet Union, Mongolia began to turn to market economy, and eagerly made effort to open and reform. With the expanse of trade and economy cooperation between South Korea and Mongolia, Mongolia started its sea road expanding. And the south Korea went to inland to get the necessary resources. Both of them feed its needs and obtain its profits.

The present time this country is faced with general hospital building remodeling time from the constructing age. In architecture, one of the reconstruction of consciousness, remodeling significance Is restoration of capacity a generally structure. Through this research we acquire concluding remarks. 1) In hospital extension and reconstruction works set a different counterplot proportionately with part that are the ward areas, the outpatient areas, the diagnosis/treatment areas, the supply areas, the administration areas, the education/research areas, the miscellaneous areas etc. According to department's character and use various purposes take proper measures. Then it estimation that remodeling study shall be need. 2) It is advisable the way of connection the existing facilities if it extended case. The case of K hospital has been extended outskirts the main building. As this an enlargement of a outhouse has an advantage that secure construction area at a stretch and no exert Influence on both nature lighting and construction matter. On the contrary caused [defect that is repeatedly occur a faculty relocation and the inner part alteration because of it\`s post transfer.
