The purpose of this exploratory study was to investigate how the information society affected the attitude about the family/kinship life of Netizen. For this goal, the data were collected from 305 Netizen who use the Internet. The major findings were as follows. Firstly, In Netizen, the support to familism and boy preference was low level. Secondly, in their altitude to the divorce and remarriage, there was a tendency which accepts a marriage with selection. Thirdly, they had a tendency to agree equal partnership in couple relationship. Fourthly, virtual community in cyber-space was found, but the loyalty of members was not enough strong. Fifthly, in the family/kin rites, it was showed non-traditional tendency. And in all aspects, some differences were found between men and women. The findings of the present study suggest that the couple relationship in the information society becomes more important, and there is a tend to increase acceptability to increase. In contrast, there is stiff another discrimination in cyber-space by focusing on traditional mother route.

In this paper, research for use possibility as silica source of waste concrete powder discharged from direct and indirect carbonation has progressed. For the research, properties on the extruding panel using waste concrete powder with high silica content is evaluated. As the results, compressive strength of specimen is increased 24% compared to control specimen when waste concrete powder replaced 50%, that is discharged from carbonation process, as silica source.

웹을 이용한 많은 양의 데이터의 분산 처리 방식이 XML 등장 이후 보다 가속화 되고 있다. 하지만 지금까지의 어플리케이션간 데이터 전달 방식은 단순히 데이터의 직렬화와 데이터를 처리하기 위한 외부 함수 호출 등의 전달을 위주로 제안된 XML 프로토콜을 중심으로 개선되어 왔다. 이에 본 논문에서 제안하는 APEX(Application Program Embedded XML) 시스템은 방대한 양의 데이터를 분산된 각 MiniServer에서 기존의 어플리케이션 혹은 사용자가 직접 제공한 어플리케이션을 통해 처리하여 그 결과 값을 원 데이터와 어플리케이션과 함께 데이터베이스에 HTML 문서와 XML 문서의 형태로 저장한 후, 사용자에게 되돌려주는 시스템으로 대용량 데이터 처리에 드는 비용을 줄여주는 효과를 보인다.

This paper represents the study on the development of semi-active bicycle suspension system. The road vibration and transmissibility of front suspension are obtained by driving test on proving ground. The numerical simulation is evaluated by dynamic system modeling and equation of motion. The numerical simulation are performed to estimate the optimal damping force for minimal vibration transmission. And oscillating displacement is calculated and analyzed. Therefore the stoke which convert the damping characteristics is suggested from the driving test and numerical simulation.

This study was conducted to test the effect of chitosan, grape fruit seed extracts(GFSE) and sodium hypochloride gas on the control of mycotoxin producing pathogens occurred kin postharvest grains. Among the treatments, sodium hypochloride gas showed the highest control effect on wheat, soybean and corn see maintained in natural conditions after postharvest and GFSE had a little control effect, but chitosan treatment had no effect. Sodium hypochloride gas exhibited the strongest control effect on the major mycotoxin producing pathogens such as Penicillium spp. Aspergillus spp. and Fusarium spp., whereas GFSE had a little control effect. Sodium hypochloride gas appeared to be effective when the grains were treated with this gas more than 24 hours.

Adventitious multiple shoots were developed from leaf, petiole and internode explants of Geophila reniformis D. Don. on MS medium supplemented with various concentrations of $N^6$-benzylaminopurine (BAP) or Kinetin (KIN) alone or in combination with indole-3-acetic acid (IAA). Leaf showed maximum organogenetic potential, followed by petiole and internode. Murashige and Skoog (MS) medium supplemented with 22.22 $\mu{M}$ BAP and 4.57 $\mu{M}$ IAA induced maximum shoot buds from leaf explants. Internodal segments showed low potential of direct organogenesis. The regenerated shoots rooted the best in presence of 10.75 - 13.44 $\mu{M}$ $\alpha$-naphthalene acetic acid (NAA) along with 2.22 $\mu{M}$ BAP, and were successfully established in the field with a survival rate of 89.11%.

XML의 등장 이후 인터넷을 이용한 다량의 데이터의 분산 처리 방식이 보다 가속화되고 있다. 이에 본 논문에서는 이러한 분산 처리의 개념을 다수의 수신자에게 같은 내용의 이메일을 보내는 경우에 적용을 하고자 한다. 사용자는 한 사람의 수신자에게 메일을 보내는 것과 같이 메일 에이전트를 통해 메일을 보낼 수 있으나 메일 에이전트는 수신자의 수와 내용의 크기를 토대로 분산되어 있는 메일 시스템인 APEX-MAIL(Application Program Embedded XML-MAIL) 시스템의 각 서버로 메일의 내용과 수신자들의 목록을 XML문서로 만들어 보내며 XML문서를 전송 받은 메일서버들은 각각의 수신자에게 메일을 보내는 것이다. 따라서 본 논문에서 제안하는 APEX-MAIL 시스템은 대용량의 메일을 보냄에 있어 드는 비용을 효과를 줄여주는 효과를 보인다.

This study explores the overall social activities of the middle-aged women. The middle-aged married women of this study are the 40-59 years old and having youngest child above 10 years. Their social activities are categorized into work activities leisure avtivities social network with kin friends and neighbors and religious activities. The results are summarized as follows: (1) The work activities of he middle-aged married women are characterized by stable employment preparation of reentry to the job worries of unemployment and preparation of retirement(2) The leisure activities of the middle-aged married women are devided into two styles; family oriented activities and self developing activities. (3) In social networks especially the social relation with neighbor are increased and the relation with kinship tends to be bilineages. (4) Their religious activities are more supported by families than other activities. From he result this study suggests that : (1) The middle-aged m rried women might accept their midlife as a developmental stage. (2) The volunteer activities might be extended throughout the social activities (3) New social education programs for helping women's growth might be developed.

Following their applications in cardiology, ophthalmology and dentistry among others, the advent of lasers in dermatology and urology had become the success story of the past decade. Laser-assisted treatments in dermatology and urology are mainly based on the laser-induced tissue injury/coagulation and/or ablation, depending upon the desirable clinical endpoint. In this review, we discussed the underlying mechanisms of the laser induced tissue ablation. In any medical laser application, the controlled thermal injury and coagulation, and the extent of ablation, if required, are critical. The laser thermal mechanism of injury is intricately related to the selective absorption of light and its exposure duration, similarly to the laser induced ablation. The laser ablation mechanisms were categorized into four different categories (the photo-thermally induced ablation, the photo-mechanically induced ablation, the plasma induced ablation and the photoablation) and their fundamentals are herein described. The brief history of laser treatment modality in dermatology and urology are summarized.

In this paper the vibration system is consisted of a rotating cantilever pipe conveying fluid and a tip mass. The equation of motion is derived applying a modeling method that employs hybrid deformation variables. 'TI1e influences of the rotating angular velocity, mass ratio and the velocity of fluid flow on the stability of a cantilever pipe are studied by the numerical method. The effect of tip mass on the stability of a rotating cantilever pipe are also studied. The influences of a tip mass, the velocity of fluid the angular velocity of a cantilever pipe and the coupling of these factors on the stability of a cantilever pipe are analytically clarified.
