Hemorrhagic cystitis is potentially life-threatening sequellae of chemotherapy using oxazaphosphorine alkylating agents (cyclophosphamide and ifosfamide). Mesna contains a sulfhydryl group that is believed to bind acrolein within the urinary collecting system and reduce the hemorrhagic cystitis without affecting the chemotherapeutic potential. To date, about thirty cases of hypersensitivity or allergic reactions of the delayed and urticarial type associated with mesna have been reported. We reported two patients with systemic lupus erythematosus who developed facial rash and flushing associated with mesna which imitate malar rash.

Presented in the paper is a reservation based dispatching rule to achieve the on-time delivery in system LSI (large scale integrated circuit) semiconductor fabrication (FAB) with urgent orders. Using the proposed reservation based dispatching rule, urgent lots can be processed without waiting in a queue. It is possible to achieve the on-time delivery of urgent orders by reserving a proper tool for the next step in advance while urgent lots are being processed at the previous step. It can cause, however, tardiness of normal lots, because the proposed rule assign urgent lots first. To solve this problem, the proposed rule tries to find the best tool for the reservation in the tool group, which can minimize idle time, and the reservation rule is applied at all tools except for photolithography tools (bottleneck). MOZART® which is developed by VMS solutions are used for simulation experiments. The experimentation results show that the reservation based dispatching rule can achieve the on-time delivery of normal lots as well as urgent lots.

With using adaptive control of the resistance spot welding machine, the advantage on electrode life time for galvanized steels has been addressed. This study was aimed to evaluate the electrode life time of galvanized steels with applying the constant current control and the adaptive control resistance spot welding process for a comparison purpose. The growth in diameter of electrode face was similar for both the constant current and the adaptive control up to 2000 welds. The button diameter was decreased with weld numbers, however, sudden increase in button diameter with use of the adaptive control after 1500 welds was observed. The peak load was continuously decreased with increasing number of welds for both the constant current and the adaptive control. The current compensation during a weld was observed with using the adaptive control after 1800 welds since the ${\beta}$-peak on dynamic resistance curve was detected at later weld time. The current compensation with adaptive control during resistance spot welding enhanced the nugget diameter at the faying interface of steel sheets and improved the penetration to thinner steel sheet.

N/A objective : This study was performed to determine if two ginseng species(Korean Ginseng and American Ginseng) could be identified by genetic analysis and to verify Pyrosequencing analyses, which was used to assess genetic variation. method : The DNAs of Panax species were extracted, and we have investigated the typing single-base variations of Panax species in DNA by using Pyrosequencing. result : The Pyrosequencing results showed clear data. American ginseng showed different pattern compared with Korean ginseng. The peak of American ginseng was very week in the first T nucleotide base but The peak of Korean ginseng was very high in the first T nucleotide base. conclusion : Pyrosequencing analysis might be able to provide the identifying the Panax species(Korean Ginseng and American Ginseng).

The methodology and process of this study is following: 1)Analysis on the changes of Jung~dong throughout its history and understanding of its substance in order to respond to the surroundings of the site. 2)Looking into how the changes of recognizing perimeter are applied to spatial representation of architecture in various ways. 3)Looking for the most suitable method to relate the building with its surroundings considering flows of people, information, etc. and finally configuring principles of architectural organization. The objective of this study are: 1)To design the space for events, ie staying which ambiguous characteristics of perimeter are embodied by indeterministic movement of people, 2)To propose the International Center for Cultural Interchange which is able to activate cultural elements found all over Jung-dong.
