When rate of stated and public owned demesne in residential environment improvement is low under the limited resources of revenues, the new infrastructure for the maintenance of the existing estate has increased land reduction rate thus the place where lot of small estate find it difficult to accept as the feature of residential environment improvement. Although 'Diffusion model of residential environment improvement' which designed to overcome existing residential environment improvement, is middle of progress, there is not any suggestion made to solve problem caused by short of estate in order to maintain small estate and total Infrastructure. In feature of resident, we also notice ageing not only facilities and building. 'Elderly housing' can be presented as an alternative living style to solve housing and elderly matter which are caused by accumulation of individual estate and aging at once. Therefore, this research identifies resident's perception about elderly housing and recognizes task and potentialities that has to be solved in order to apply virtually to residential environment improvement.

Background : Medical records thought to be reflecting the quality of medicine. By this ground, examination of medical records can be served to evaluate, and to improve the quality of medical care. To examine the medical records, we need some standards or checklists which can be used to sort out the problems. Methods: We developed checklists for medical records evaluation. We studied 1,677 medical records about its completeness using this checklists in one educational hospital. Survey was completed by 5 well trained staffs of medical record department. Results are analyzed. SPSS/PC+ program was used for statistics. Results : 13.8% of discharge summary was incomplete. Recording of the demographic information was also poor in incomplete medical records compared to complete ones. Progress note was recorded average 4.16 times during 11.9 hospital days. After 4th hospital day, recording rate of progress note dropped sharply. Rate of professor's signature on operation records was poor(27%). He or she who described the discharge summary well also wrote progress note well. Conclusions: Fill-up of demographic date should be stressed during medical record education program. Strategy to create the environment emphasizing the responsibility of professor on quality medical record should be made. We suggest new index (number of records/hospital stay) for the evaluation of completeness of progress note.

The horticultural seed industry has made great progress in the last fifty years of its history after the independence of this country. The industry has accomplished self-sufficiency in major vegetable seeds and has even gained international competitive edge in certain crop seeds, particularly in hybrid cultivar development. However, the industry is facing a crisis at present coming from excessive competition among the domestic seed companies as well as the foreign currency crisis of the country. Several major seed companies have already been acquired by multinational corporations. Many people in the country as well as agriculturists are concerned about this situation. Although it is true that the industry is undergoing hard times, this crisis can be turned into a chance for making new progress depending on the joint efforts of the groups responsible, i.e., private companies, public institutions, and policy makers. Therefore, we have to turn this crisis into an opportunity for self-reform and progress. We should not be discouraged or give up. We Propose some ideas for the Progress of the seed industry. Public institutions and policy makers should do such things in cooperation as 1) training human resources for future breeders, 2) securing a wide range of genetic resources and improvement of the management system, 3) basic science research including biotechnology, 4) releasing breeding stocks from germplasm enhancement through use of exotic accessions, 5) support for breeding region- or use-specific cultivars, and 6) collection of foreign agricultural information for breeding cultivars for overseas markets. Eventually the responsible group for the final development of commercial cultivars, production, sales and management is private companies. Therefore, private companies also should have to do their best to develop competitive cultivars with a missionary spirit and endeavor for both domestic and overseas markets in cooperation with public institutions. Management based on competition, professionalism and rationalism is also urged. We are going to conclude with optimism that we can make a new vault of progress once the private and public sectors closely cooperate for the development of Korean horticultural seed industry by overcoming this crisis.

The effects of the proprotion of cows inseminated by young A. I. bulls on genetic improvement in the Japanese Holstein population were examined using a simulation technique. The proportion of recorded cows inseminated by young A. I. bulls was assumed to be from 10% to 100% of the total number of recorded cows. The expected total genetic improvement was estimated for all cows and recorded and non recorded cows. The effects of the above were remarkable in the schemes that proven sires were used to produce recorded and non recorded cows for a limited time. Also the increase in the rates for -the expected total genetic improvement was larger when the proportion of recorded cows that were inseminated by young A. I. bulls was about 10% to 40%. When the expected total genetic improvement was estimated for the entire population, we found that the highest values were in a range of about 40 to 60% recorded cows that were inseminated by young A. I. bulls. On the other hand, the expected total genetic improvement that was only estimated in recorded cows dramatically decreased for more than 40% of the recorded cows. The results of this study showed that the optimal proportion of recorded cows inseminated with young A. I. bulls should be about 30% in the Japanese Holstein population.

With the increasing advances in Brassicaceae genetics and genomics, considerable progress has been made in the transformation of Brassicaceae. Transformation technologies are now being exploited routinely to determine the gene function and contribute to the development of novel enhanced crops. $Agrobacterium$-mediated transformation remains the most widely used approach for the introduction of transgenes into Brassicaceae. In $Brassica$, the transformation relies mainly on $in$ $vitro$ transformation methods. Nevertheless, despite the significant progress made towards enhancing the transformation efficiencies, some genotypes remain recalcitrant to transformation. Advances in our understanding of the genetics behind various transformations have enabled researchers to identify more readily transformable genotypes for use in routine high-throughput systems. These developments have opened up exciting new avenues to exploit model $Brassica$ genotypes as resources for understanding the gene function in complex genomes. Although many other Brassicaceae have served as model species for improving plant transformation systems, this paper summarizes on the recent technologies employed in the transformation of both $Arabidopsis$ and $Brassica$. The use of transformation technologies for the introduction of desirable traits and a comparative analysis of these as well as their future prospects are also important parts of the current research that is reviewed.

As climate change is increasingly recognised as an important global problem, a wide variety of policies and measures are emerging at global and local level to deal with the challenges from the anthropogenic global warming. While national and inter-national efforts characterized by limiting GHG emissions shows very little progress because of their expanse spatial scale and complicated political situations, local efforts have the potentials to ensure effective implementation, monitoring and continual improvement. In the context of local-scale climate policy, the city of Portland is known as one of the best leading cities for its progress of implementing climate change strategies. This paper will briefly discuss the city's efforts to solve the climate change problem and its achievements. The latest climate action plan is selected for the analysis on the followings; the framework of the action plan, the types of implementation methods, and the coordinating agencies. The progress status of each action plans is also reviewed. The purpose of this paper is to describe the main characteristics of the climate action plans and their implications from the intensive analysis on the city of Portland's case.

Halide perovskites are emerging materials for next-generation display applications, thanks to their narrow emission linewidth and band gap tunability, capable of covering the entire range of visible light. Despite their short period of research, perovskite light emitting diodes (PeLEDs) have shown rapid progress in device external quantum efficiency (EQE) in the near-infrared (NIR), red, and green emission wavelengths, and the record EQE has exceeded over 20 %. However there has been limited progress with blue emission compared to the red and green counterparts. In this review, the current status and challenges of blue PeLEDs are introduced, and strategies to produce spectrally stable blue PeLEDs are discussed. The strategies include 1) a mixed halide system in the form of 3-dimensional (3D) perovskites, 2) colloidal perovskite nanocrystals and 3) low dimensional perovskites, known as quasi-2D perovskites. In the mixed halide system, previous reports based on the compositional engineering of 3D perovskites to reduce spectral instability (i.e., halide segregation) will be discussed. Since spectral instability issue originate from the mixed halide composition in perovskites, the two other strategies are based on enlarging the band gap with a single halide composition. Finally, the prospects for each strategy are discussed, for further improvement in spectrally stable blue PeLEDs.
