In this paper, we conducted experiments on damaged patterns of incandescent lamps by external stress, such as external flame or external impact. Glass bulbs were melted and filaments were evaporated by external flame when the bulbs were lit, and finally molten marks were recognized at the filaments. Also, there were some differences in absorption patterns of evaporated filament elements according to set-up directions, and evaporated filament elements were absorbed in lead-in wires, support, inside of glass. In case the bulbs were lit and they were damaged by external impacts, filament burned out. Filaments were not evaporated but melted. We expect that this results could be used to judge whether electric current flew through incandescent lamps or not in fire site.

We examine whether the attributes of patented knowledge have any impact on its chances of commercialization. It has been hypothesized that the scope and cumulativeness of patented knowledge would positively affect the likelihood of its commercialization. The hypotheses were tested using patents data on the US biotechnology and pharmaceutical industries. We found support for the prediction that the scope of patented knowledge increases the likelihood of commercialization, but we didn't find support for the cumulativeness aspect. These findings have important implications for firms that develop patentable knowledge, license-out patents, license-in patents from external sources, or debate about patenting strategy.

The most important goal of records management is to document the administrative responsibility of the institution producing records and its history. For this purpose, each institution needs to make a plan determining kind and value of phenomena and evidences to be documented, that is, a plan for documentation. This study was aimed to present its necessity and stretagy, focussing on the documentation of correlations with external factors surrounding National Assembly (external relations). Through literature survey, external relation functions of congress and important sources associated with their functions were analyzed. and what records were produced from those sources was investigated in the case of U.S. Congress. Comparing with the present state of National Assembly on this basis, four significant subjects to activate the external relations documentation plan in the point of institutional policy of National Assembly were proposed : legislation of documentation program of external relations, acquisition policy, advocacy enforcement for National Assembly Documentation, and establishment of cooperation and support systems with external factors.

There is no agreed definition of intelligence. The ability to adapt to the environments is a kind of intelligence. Expert functionally recognize environment using their five senses, and acquire and memorize knowledge necessary for operating machines. Knowledge that they cannot acquire directly is acquired in indirect ways. The purpose of intelligence machines is applying to machines experts' knowledge acquisition process and their skills in operating machine. An agent is an autonomous process that recognizes external environment, exchanges knowledge with external machines and performs an autonomous decision-making function in order to achieve common goals. This paper describes agent application for intelligence machine.

Diverse strengthening methods for reinforced concrete are applied to real structures with a variety of materials. On the other hand, only external prestressing is used for strengthening damaged prestressed concrete girders. But the end brackets for external prestressing are hard to design and to manufacture, the magnitude of prestressing is limited when applied to real structures. The current end brackets are not clearly understood in load transmitting mechanisms and they may damage the original girder by drilling during construction. And also the designed welding area of the current bracket is insufficient to support the high load. The problems of current end bracket are solved in this study. And a new and improved end bracket is proposed and tested. The tested end bracket is similar to the end bearing bracket, but many supportting plates are addded to increase its welding length of the weakest point of the bracket. The increased welding length finally increases its load carrying capacity significantly.

A comparative wind tunnel testing of an airplane model was performed at the Korea Aerospace Research Institute Low Speed Wind tunnel(KARI LSWT). The model used for the comparative test was a seaplane model from the Glenn L. Martin Wind(GLM) Tunnel of University of Maryland, U.S.A. The 6-component external balance used in force and moment measurement is pyramidal type, which is a precision device that has strain gauge-type load cell inside of balance and the virtual center of the balance coincides with the tunnel centerline. Image method is adopted to eliminate the tare and interference of the model support, and to correct the flow angularity to the model also. Test results from KARI LSWT were compared with the results from GLM tunnel.

This study examines the effect of external environments such as technological change and competitive intensity on standardization. It was empirically tested by a Korean sample to verify the validity of the research framework. The empirical result confirms that external environments increase the odds of marketing standardization and technology standardization. The result also indicates that technology change and global standardization are related. The data support that firms facing a high rate of technology change stress marketing and technology standardization. The result also confirms that competitive intensity directly influences marketing standardization.

The 150 gal Ion EFT(External Fuel Tank) used to enlarge the aircraft operation range was adopted an import equipment in T-50 FSD phase. But in Production phase the EFT was planed to develop for the stable ILS(Integrated Logistics Support) and technical ability improvement by using the composite materials. The design for configuration and fuel system is intended to maintain compatibility with aircraft systems and the development test is performed on component, assembly and aircraft. This study is conducted to provide the technology of design and test for the 150 gallon composite EFT in LRU level. The test results show that the composite EFT is satisfied with structural, functional and environment requirements which are described in specification.

This paper is attempted to clarify the controversial event King Thibaw ascending the throne. Moreover it was presented with the purpose of how important "Trust Building" is in politic. After ascending the throne, King Thibaw faced external threat as well as internal weakness. The Hluttaw ministers and counselors did not support effectively and King Thibaw lost trust his ministers and counselors. Therefore mass killing of royal prince took place after the ascending the throne and it made discredit to King Thibaw. Senior minister like Kinwun Mingyi and Hsinphyumashin secretly contact with Prince Nyaung Yan whom was staying under the protection of British. On the other hand Prince Myingun took refuge under protection of the French and was trying to seize the power with the supporters from lower Myanmar as well as taking the financial help from Hsinphyu Mashin. They were external strength for the British and French. In this way King Thibaw's administration became deteriorated and finally the British anxious about Franco-Myanmar treaty so they exaggerated the Bombay-Burma Teak company's problem. In this way King Thibaw was taken away by the British due to the internal weakness and external strength.

This study examined moderating effects of mother's support and community environment on relationships between after school self-care and problem behaviors. Subjects were 579 3rd and 6th grade elementary school children. Major findings were positive relationships between after school self-care and problem behaviors. Neither gender differences nor grade differences were found in the relationships between after school self-care and problem behaviors. Moderating effects of care by relatives or neighbors on mother's support was shown in the relationships between after school self-care and internal problem behaviors. Moderating effects of proximity to harmful facilities were found in relationships between after school self-care and external problem behaviors.
