This study summarizes the use of satellite data to detect the change of southwestern coastal wetlands in Korea. The images used for this study were two Landsat Thematic Mapper(TM) images (June 12, 1984 & June 2, 1992). TM images were used to classify such different types of wetlands as aquatic bed, nonaquatic bed and other land use in the region. Then it, was possible to a) determine the status of wetlands using image classification products, and b) detect the changes of various types of wetlands influenced by both human and nature. The results from spatiotemporal analysis showed that approximately 120 lad of coastal wetlands were lost from the year of 1984 to 1992. 71 % of the lost wetlands were converted to the reclaimed land. This loss of wetlands has been causing the profound environmental impacts. It has been successfully proved that satellite data are very effective for spatiatemporal change analysis, especially for that of coastal wetlands.

The properties related to the temperature and oxygen stability of the cytoplasmic hydrogenases from the fermentative strict anaerobic bacterium, Clostridium butyricum NCIB 9576 (Cl. butyricum), and purple sulfur phototrophic bacterium, Thiocapsa roseopersicina NCIB 8347 (T. roseopersicina), were compared. The optimum temperatures for the growth of Cl. butyricum and T. roseopersicina were 37$^{\circ}C$ and 25$^{\circ}C$, respectively, whereas those for the H$_2$ evolution of the cytoplasmic hydrogenases prepared from Cl. butyricum (C-H$_2$ase) and T. roseopersicina (T-H$_2$ase) were 45$^{\circ}C$ and 65$^{\circ}C$, respectively. The T-H$_2$ase was more thermostable than the C-H$_2$ase and retained its full activity for 5 h at 50$^{\circ}C$ under anaerobic conditions and 90% of its activity at 60$^{\circ}C$, whereas the C-H$_2$ase lost its activity drastically at 50$^{\circ}C$. The optimum pHs for H$_2$ oxidation of the C-H$_2$ase and T-H$_2$ase were 9.0 and 7.5, respectively. Both enzymes showed a maximum H$_2$ evolution activity at pH 7.0. Under aerobic conditions, 80% of the T-H$_2$ase activity was retained for 10 h at 30$^{\circ}C$, and 50% of the activity remained after 6 days under the same experimental conditions. However, the C-H$_2$ase was labile to oxygen and lost its activity immediately on exposure to air. Therefore, these properties of the T-H$_2$ase are expected to be advantageous for application in in vitro biological H$_2$ production systems.

For the effective immobilization of urease on chitosan matrix with glutaraldehyde, optimal activation methods were studied, and its enzymatic properties was investigated. In the stability of enzyme. the retained activity of the native urease was 55% after it was soaked af pH 7 for 10 hrs., while the retained activity of immobilized one was about 62% after soaked at pH 6.5-8.5 for the same time. After heat treatment at $60^{\circ}C$ for 10 hrs., the native urease lost the most of its activity, while immobilized urease retained 54% of its activity by the same treatment. The retained activity of immobilized urease did not decrease nearly when it was stored at room temperature for 25 days. From Linweaver-Burk plots, the $V_{max}$ value of native urease was $66{\mu}M/l$ and that of immobilized urease was $41{\mu}M/l$, while Km value 40mM/l for both enzymes was unaltered.

이 논문은 동기적 검사점 기법에서 결한 포용을 목적으로 불안전 저장 장치(volatile storage)에 저장되는 메시지 로그와 안전 저장 장치에 저장되는 검사점의 쓰레기 처리 기법을 제안한다. 기존의 동기적 검사점 기법을 기반으로 한 결함 포용 정보 쓰레기 처리 기법은 가장 최근의 검사점을 제외한 모든 결함 정보를 쓰레기 처리하였다. 하지만 TCP/IP와 같은 신뢰적 통신 기법을 기반으로 한 동기적 검사점 기법이 가장 최근의 검사점만을 복귀 회복 기법에서 사용한다면, 손실 메시지(lost message)로 인한 불필요한 복귀(sympathetic rollback)가 발생된다. 이 논문은 동기적 검사점 기법에서 손실 메시지로 인한 불필요한 복귀 문제를 해결하기 위해 각 프로세스가 동기화된 가장 최근의 검사정의에 검사점이나 메시지 로그를 유지해야 한다는 것을 보였다. 또한 손실 메시지로 인한 불필요한 복귀 문제의 해결을 위해 관리되어야 하는 검사점이나 메시지 로그가 쓰레기 처리되어지기 위해 필요한 조건을 새롭게 정의하며, 이 정의를 기반으로 한 검사정과 메시지 로그의 쓰레기 처리 알고리즘을 제안한다. 제시된 조건을 기반으로 한 검사점과 메시지 로그의 쓰레기 처리는 송수신 메시지에 부가된 손실 메시지 관련 프로세스 정보를 이용하므로 쓰레기 처리를 위한 부가적인 메시지를 발생시키지 않는다. 제안된 기법은 손실 메시지 관련 정보가 부가된 메시지가 송수신되기 전까지 쓰레기 처리가 지연되는 '지연 쓰레기 처리 현상(lazy garbage collection)'을 발생시킨다. 하지만 '지연 쓰레기 처리 현상'은 분산 시스템의 일관성을 위배하지 않는다.

The parameter design is the most emphasized measure by researchers for a new products development. It is critical for makers to achieve simultaneously in both the time-to-market production and the quality enhancement. However, there are difficulties in practical application, such as (1) complexity and nonlinear relationships co-existed among the system's inputs, outputs and control parameters, (2) interactions occurred among parameters, (3) where the adjustment factors of Taguchi's two-phase optimization procedure cannot be sure to exist in practice, and (4) for some reasons, the data became lost or were never available. For these incomplete data, the Taguchi methods cannot treat them well. Neural networks have a learning capability of fault tolerance and model free characteristics. These characteristics support the neural networks as a competitive tool in processing multivariable input-output implementation. The successful fields include diagnostics, robotics, scheduling, decision-making, prediction, etc. This research is a case study of spherical annealing model. In the beginning, an original model is used to pre-fix a model of parameter design. Then neural networks are introduced to achieve another model. Study results showed both of them could perform the highest spherical level of quality.

The objective of this study is to investigate the process of development of social work and divide it historically during the Korean Modern Times. At first, I investigated this period's "societal" situation (political, economical, social situation) which is closely related to social work and made a historical division. And I wrote down the social welfare policy and social services concretely and I interpreted this period's historical meaning. At the end of the Cho-Sun dynasty, although a modern social work movement had come about naturally in the Korean peninsula, it was nearly destroyed by the Japanese aggression. However, it could have expanded consistently and come to maturity because of a national self-awakening and peoples' vigorous participation after the 3 1 national movement. But unfortunately, as the social work come to be exploited by the Japanese Imperialist powers, it lost its purity its essential purpose and was changed. After World War II, no one was made to take responsibility for those historical facts, and under the name of Social Welfare many ordinary citizens became scapegoats, and passed silently over to the period of American military occupation which was another time of transition in the Korean peninsula. There have been few studies undertaken concerning social welfare during the Japanese occupation. These studies will help to indicate what influence the Japanese had on the development of Korean social welfare after the Japanese occupation. I anticipate many studies on this subject will follow.

Sun Yung Shin's poetry collection Skirt Full of Black (2007) brings the author's personal history as a Korean female adoptee to bear upon poetic language in daring formal experiments, instantiating the liminal state of being shuttled across borders to land in an in-between state of marginalization. Other Korean American poets have also drawn on the experience of transnational adoption and racialization explore the literary potential of English to materialize haunting memories or the untranslatable yet persistent echoes of a lost home that gestures across linguistic boundaries, as seen in the case of Lee Herrick or Jennifer Kwon Dobbs. Shin however dismantles the referential foundation of English as a language she was transplanted into through formal transgressions such as frazzled syntax, atypical typography, decontextualized punctuation marks, and phonetic and visual play. The power to signify and thereby differentiate one entity or meaning from another dissipates in the cacophonic feast of signs in Skirt Full of Black; the word fragments of identificatory markers that turn racialized, gendered, and culturally contained subjects into exotic things lose the power to define them as such, and instead become alterities by departing from the conventional meaning-making dynamics of language. Expanding on the avant-garde legacy of Korean American poets Theresa Hak Kyung Cha and Myung Mi Kim to delve further into the liminal space between Korean and American, referential and representational, or spoken and written words, Shin carves out a space for discreteness that does not subscribe to the hierarchical ontology of differential value assignment.
