Purpose: The purpose is to expand the role of local senior welfare centers as a place for intergenerational integration by analyzing the intergenerational awareness and satisfaction of participants in the intergenerational integration program. Research design, data and methodology: The empirical study conducted a survey on 205 participants (114 seniors, 91 teenagers) of the generation integration program being implemented at a senior welfare center located in Seoul. Results: Regarding the satisfaction of participants in the generation integration program, both the elderly and youth showed that the more contact they had between generations, the higher the satisfaction with participation. In the case of the elderly, the better the subjective health status, the older the respondent, and the lower the educational level, the higher the satisfaction, and the more frequently they met youth, the higher the satisfaction. On the other hand, the longer the youth participated in the program, the weaker their negative emotions toward the elderly, and the higher the degree of visits to grandparents, the higher their satisfaction with participation. Conclusions: The biggest determinant of satisfaction with the generational integration program at senior welfare centers is the intensity and frequency of contact between the elderly and youth generations.

Recently a new multi-attribute analysis method is one of the evident areas of important points in the decision support system analysis. The area of decision support system may be broken into three primary area: idea generation, multi-attribute structured analysis method, and the integration of the results of analysis. This research developed an internet/intranet-based solution builder for a three-step decision support system in the view of 1) brainstorming for the idea generation, 2) analytic hierarchy process as a multi-attribute structured analysis method and 3) aggregating logic model to integrate the results of individual analysis. A computer program is developed and demonstrated in internet/intranet-based decision problem. This solution builder provides decision makers a good tool for remote group decision making.

This study was aimed at examining the effect of the intergenerational program on the attitudes and intimacy between the elderly and children. The pretest-posttest quasi-experimental design was used. The subjects were 232 old persons and 1,687 infants or children. The experimental programs was composed of 232 programmes focused on the education by the elderly and each program was implemented for three months and over. The results of this study showed that the attitude toward other generation of the elderly and children was changed significantly positive and the intimacy between two generations was increased significantly higher after participating in the experimental programmes. Based on the results, the various long-term intergenerational programmes need to be developed and implemented.

A routine system based on particle bombardment of embryogenic callus for recovery of fertile transgenic rice (Oryza sativa L.) plants was developed. Embryogenic callus was established within 2-3 months from calli derived from mature seeds of Korean rice cultivar, Nagdongbyeo. The callus was bombarded with the plasmid pRQ6 containing the $\beta$-glucuronidase gene (gusA) and hygromycin phosphotransferase gene (hph, conferring resistance to hygromycin B), both driven by CaMV 35S promoter. Placement of cells on an osmoticum-containing medium (0.2 M sorbitol and 0.2 M mannitol) 4 hrs prior to and 16 hrs after bombardment resulted in a statistically significant increase with 3.2-fold in transient expression frequency gusA. In five independent experiments, the average frequency of transformation showing GUS activities was $8.86\%$. A large number of morphologically normal, fertile transgenic rice plants were obtained. Integration of foreign gene into the genome of $R_0$ transgenic plants was confirmed by Southern blot analysis. GUS and HPT were detected in $R_1$ progeny and Mendelian segregation of these genes was observed in $R_1$ progeny.

New generation of tall and complex buildings systems are now introduced that are reflective of the latest development in materials, design, sustainability, construction, and IT technologies. While the complexity in design is being overcome by the availability and advances in structural analysis tools and readily advanced software, the design of these buildings are still reliant on minimum code requirements that yet to be validated in full scale. The involvement of the author in the design and construction planning of Burj Khalifa since its inception until its completion prompted the author to conceptually develop an extensive survey and real-time structural health monitoring program to validate all the fundamental assumptions mad for the design and construction planning of the tower. The Burj Khalifa Project is the tallest structure ever built by man; the tower is 828 meters tall and comprises of 162 floors above grade and 3 basement levels. Early integration of aerodynamic shaping and wind engineering played a major role in the architectural massing and design of this multi-use tower, where mitigating and taming the dynamic wind effects was one of the most important design criteria established at the onset of the project design. Understanding the structural and foundation system behaviors of the tower are the key fundamental drivers for the development and execution of a state-of-the-art survey and structural health monitoring (SHM) programs. Therefore, the focus of this paper is to discuss the execution of the survey and real-time structural health monitoring programs to confirm the structural behavioral response of the tower during construction stage and during its service life; the monitoring programs included 1) monitoring the tower's foundation system, 2) monitoring the foundation settlement, 3) measuring the strains of the tower vertical elements, 4) measuring the wall and column vertical shortening due to elastic, shrinkage and creep effects, 5) measuring the lateral displacement of the tower under its own gravity loads (including asymmetrical effects) resulting from immediate elastic and long term creep effects, 6) measuring the building lateral movements and dynamic characteristic in real time during construction, 7) measuring the building displacements, accelerations, dynamic characteristics, and structural behavior in real time under building permanent conditions, 8) and monitoring the Pinnacle dynamic behavior and fatigue characteristics. This extensive SHM program has resulted in extensive insight into the structural response of the tower, allowed control the construction process, allowed for the evaluation of the structural response in effective and immediate manner and it allowed for immediate correlation between the measured and the predicted behavior. The survey and SHM programs developed for Burj Khalifa will with no doubt pioneer the use of new survey techniques and the execution of new SHM program concepts as part of the fundamental design of building structures. Moreover, this survey and SHM programs will be benchmarked as a model for the development of future generation of SHM programs for all critical and essential facilities, however, but with much improved devices and technologies, which are now being considered by the author for another tall and complex building development, that is presently under construction.

The purpose of this study is to analyze the program according to the local characteristics of the elderly welfare center and to present the development direction of the elderly welfare center in the future. The questionnaire was administered to 344 elderly welfare centers nationwide and 304 questionnaires were used for analysis. Based on the regional characteristics of the elderly welfare center, three types were derived and analyzed. The results of this study are as follows: First, the projects which showed difference according to the regional characteristics of the elderly welfare center were the functional recovery program, counseling, emotional support, and community welfare program. Second, it was found that the elderly welfare centers had different programs according to their areas. The results showed that the elderly welfare centers had different programs, group programs, self-help groups, beauty services, employment support education, economic education, retirement preparation education, home helper service, generation integration program, mobile welfare business and regional cooperation project. Based on these results, it is suggested that the development direction of the elderly welfare center is necessary to develop the program of the elderly welfare center according to the characteristics of the region and it is necessary to guarantee autonomy so that the elderly welfare center can operate the program.

Transformation of Fuji apple (Malus domestica 'Fuji') was performed using Agrobacterium tumefaciens harboring a coat protein (CP) gene of Cucumber mosaic virus (CMV). A plasmid DNA containing the virus CP and NPT II genes was introduced into the loaves of apple by th e Agrobacterium - mediated transformation procedure. Regenerated transformants of the apple were obtained by kanamycin resistance conferred by the introduced NPT II gene. PCR analysis showed that 3 out of 20 putatively selected R0 plant lines contain the CMV-CP gene. Nine putative transgenic lines out of 20 lines were investigated with the PCR analysis; 5 regenerants produced a 450 bp DNA band and 3 regenerants showed a 671 bp DNA band for the NPT II and CMV-CP genes, respectively. Southern hybyidization results demonstrate the successful integration of the CMV-CP gene into the genome of the apple. This is the first report on the generation of useful vius resistance source of transgenic apple for molecular breeding program.

We have obtained fertile transgenic rice plants resistant to the broad spectrum herbicide Bast $a^{(R)}$ (active ingredient phosphinothricin, PPT) by PEG-mediated transformation procedure. The plasmid pCaMV35S::Bar was used to deliver the bar gene into embryogenic suspension culture-derived protoplasts of rice (Oryza sativa L.). Transformed plants were regenerated and selected on medium containing 15 mg/l of phosphinothricin. Stable integration and expression of the bar gene in transgenic rice plants was confirmed by Southern and Northern blot analysis. Transgenic $R_1$ plants were also confirmed by assays for phosphinothricin acetyltransferase (PAT) activity. The bar gene was expressed in the primary transgenic rice plants and in the next generation progeny, in which it showed a 3 : 1 Mendelian inheritance pattern. Transgenic $R_1$ and $R_2$ plants were resistant to the herbicide Bast $a^{(R)}$ when sprayed at rates used in field practice.ice.

In this paper, parallel computing method on the three-dimensional electromagnetic field is proposed. The present electromagnetic scattering analysis is conducted based on the time-harmonic vector wave equation and the finite element method. The edge-based element and 2^nd -order absorbing boundary condition are used. Parallelization of the elemental numerical integration and the matrix assemblage is accomplished by allocating the partitioned finite element subdomain for each processor. The graph partitioning library, METIS, is employed for the subdomain generation. The large sparse matrix computation is conducted by MUMPS, which is the parallel computing library based on the multi-frontal method. The accuracy of the present program is validated by the comparison against the Mie-series analytical solution and the results by ANSYS HFSS. In addition, the scalability is verified by measuring the speed-up in terms of the number of processors used. The present electromagnetic scattering analysis is performed for a perfect electric conductor sphere, isotropic/anisotropic dielectric sphere, and the missile configuration. The algorithm of the present program will be applied to the finite element and tearing method, aiming for the further extended parallel computing performance.

This study analysed theory and application of holistic innovation policy in the 3rd generation innovation policy with cases of Finland and Korea. Innovation policy areas of both countries are expanding from simple goal of economic development to extensive goals such as sustainable development, quality of life, balanced growth etc. Also administrative system changed in order to let technical innovation on the center of national operation and reorganized relation and structure of relative policies like manpower, education, region policy. Particularly, Korea is in embryo standing for S&T driven society since Noh's government. But, there are differences in embodiment degree and feature between both countries. Finland reinvigorate field of public opinion due to corporatism tradition as a Scandinavian institution. Government support system developed co-program and co-policy beyond territory of individual ministry to raise policy effectiveness. However, concept of the Korean innovation policy is ahead of the times but maintained framework of developing country. And there is no active participation of private sector and civil society because transition process accomplished on the top-down method, It could hardly progress toward transition in spite of various efforts to carry out a reform.
