본 논문에서는 웹 프로그래밍 기술이 없이도 일반 사용자가 웹 데이터베이스 구축과 함께 멀티미디어 홈페이지를 작성하도록 해주는 시스템 개발을 기술한다. 본 시스템은 페이지 에디터, 웹 데이터베이스를 자동 구축해주는 데이터베이스 마법사와, 웹 데이터베이스의 생성 및 수정을 지원하는 데이터베이스 관리자로 구성되어 있다. 데이터베이스 마법사는 홈페이지 템플릿과 연동되는 데이터베이스를 자동적으로 구축하는 기능을 갖는다. 페이지 에디터는 DHTML(Dynamic Hypertext Markup Language) 컴포넌트를 기반으로 구현되었으며 멀티미디어 홈페이지를 대화형으로 쉽게 지작할 수 있게 한다. 데이터베이스 관리자는 웹 데이터베이스를 생성, 수정 및 유지보수하는 기능을 제공한다. 본 시스템은 웹 데이터베이스 프로그래밍 기술이 없이도 웹 데이터베이스와 연동되는 홈페이지 작성을 쉽게 구축하도록 하는 특징을 갖는다. In this paper, we present the development of a system that helps end-users to generate home pages with the construction of their corresponding web databases without the web programming technique. It consists of a page editor, a database wizard and a database manager. The page editor creates and modifies multimedia home pages. The database wizard generates databases operated with home pages automatically, and the database manager maintains the database related to the home pages. The page editor has been made based on the DHTML(Dynamic Hypertext Markup Language) and lets users generate multimedia home pages interactively. The database manager creates, updates and manages web databases. The system has the advantage which end-users can create multimedia home pages containing databases without requiring web database programming.

The purpose of this study was to design and develop a creeper for can-manufacturing that is simple for farmers to operate, light-weighted, endurable, mobile and not space-restricted. Specifically speaking, the most optimal conditions including the most appropriate number of blades and the most optimal power levels were experimentally investigated to design a portable creeper with a built-in compressor. The results of this study are as follows: 1. Circular grooves were cut on the cylinder axle itself to allow air pressure be carried to the blades, so that complicated links were removed easier and successive working was achieved. 2. The most appropriate number of blades for honeybee work was found to be 16 and circular blades were the most efficient. 3. The most appropriate power level for honeybee work was 700kg and the most appropriate out-length of the blades was found to be less than 2mm with scratches minimized.

In this paper, we apply a close loop transmit diversity scheme to IMT-2000 satellite systems, and investigate the performance of the scheme in both ideal and more realistic situations. We verify that the performance of the closed loop transmit diversity scheme is quite sensitive to errors in feedback information. However, we also show that the number of quantization bits for feedback information does not significantly affect the system performance when considering the feedback of phase information only. In addition, 2-bit quantized system achieves the better performance than 4-bit quantized system in terms of slot error rate.

The purpose of this study in to analyze hoe the physical activity of old adults influences on the mental health. The Simple Mental Testing was parcticed for the 100 of physical players and 60 of non-physical palyers, the total of 160, above 60 years old who live in the city of K. After that, we made a conclusion as the following; 1. When we compared the mental health of physical players with those of non-physical players, the physical activity of old physical players were certainly better than those of non-physical players in the field of somatization, fear, depression and anxiety. So, the physical activity had a good effect on the mental health of old adults. 2. When we analyzed the mental health according to the time of the physical activity, old physical players who exercised over 30 minutes were certainly better than those who did under 30 minutes in the field of somatization, fear, depression and anxiety. 3. When we analyzed the mental health according to the frequency in the physical activity, old physical players who exercised more than three times a week were better than those who did below three times a week in the field of somatization, depression and anxiety. 4. When we analyzed the mental health according to the period of the physical activity, old physical players who exercised over one year were better than those who did under one year in the field of somatization, fear, depression and indignation.

Atomism is physical and metaphysical doctrine that the world is made up of indivisible(a-tom) and imperceptible small material units. We review this doctrine and examine it physically in the light of quantum mechanics. From atomism, we elicit atomistical separability which says that properties of the whole system is determined by the properties of the parts. However, according to our argument, the atomistical separability cannot compatible with the formalism of quantum mechanics. In conclusion, atomism does not sustainable anymore, instead, holism of properties or things comes sound.

The flash point is one of the most important combustible properties used to determine the potential for the fire and explosion hazards of industrial material and the fire point is the temperature of the flammable liquid at which there will be flaming combustion, sustained 5 seconds in response to the pilot flame. In this study, the flash point and fire point were measured to present raw data of the flammable risk assessment for alcohols, using Tag open-cup apparatus(ASTM D 1310-86). The measured values were compared with the calculated values based on 0.78 times stoichiometric concentration. The values calculated by the proposed equations were in good agreement with the measured values.

A new logistics concept is needed through the sharing information between suppliers and consumers, which maximizes the customers service and its flexibility by changing functional-oriented to process-oriented. However in the real world, it is known that it takes long time to build vehicle scheduling in the process of transporting the amount of orders from the logistics center to the vendors due to the realistic constraints. This paper presents a design for each process enabling delivery planning system for the improvement logistics plant services. In addition, an interactive automatic delivery planning system is implemented utilizing the proposed algorithm.

The Flash Point is one of the most important combustible properties used to determine the potential for fire and explosion hazards of chemical materials. An accurate knowledge of the flash point is important in developing appropriated preventive and control measures in industrial fire protection. The lower flash points for the Water + n-Propanol systems were measured by using Pensky-Martens closed cup tester. The experimental data were compared with the values calculated by the laws of Raoult and van Laar equation. The calculated values based on the van Laar equation were found to be better than those based on the Raoult's law.

In this study, the highly sensitive CaSO₄:Tm-PTFE TLDs has been fabricated for the purpose of measurement of high energy electron. CaSO₄:Tm phosphor powder was mixed with polytetrafluoroethylene(PTFE) powder and moulded in a disk type(diameter 8.5㎜, thickness 90㎎/㎠) by cold pressing. The batch uniformities were average deviation 3.1%. The TLDs were determined to be R_(100)=14.5㎜, R_(50)=24.1㎜ and R_(p)=31.8㎜, respectively. The beam flatness were 4.5% as the variation of dose relative to the central axis over the central 80% of the field size at a maximum dose depth in a plane perpendicular to the central axis.
