Background: Extended-spectrum ${\beta}$-lactamases(ESBL) are enzymes that confer resistance to oxyimino-${\beta}$-lactams as well as to penicillins and cephalosporins. Strains of Klebsiella pneumoniae and Escherichia coli that produce ESBL have been increasingly prevalent in many countries. The purpose of this study was to investigate the ESBL production rate of K. pneumoniae and E. coli at the in Yeungnam University Medical Center. Materials and Methods: Thirty-one isolates of K pneumoniae and twenty-five isolates of E. coli were examined for ESBL by double disk synergy test, using 20/$10{\mu}g$ ticarcillin/clavulanic acid and $30{\mu}g$ oxyimino-${\beta}$-lactam(ceftazidime, ceftaxime, ceftriaxone and aztreonam) disks. Results: Fifty-two percent of K. pneumoniae and sixteen percent of E. coli isolates revealed double disk synergism. Majority of ESBL-producing strains(fifty-five percent) were isolated from patients in the intensive care unit. Conclusion: ESBL production of K. pneumoniae and E. coli were also common at the Yeungnam University Medical Center and pose a serious problem for antimicrobial therapy.

Convergence of information technology (IT) and medical devices enables people to measure health-related information ubiquitously, such as measuring blood glucose at home and checking cardiac signals during exercise and it allows us to access to medical care anywhere and anytime. Nowadays, the market for U-healthcare medical devices is growing rapidly, but guidelines for the evaluation of safety and effectiveness of such devices remain to be formulated. We performed a study on the development of safety and performance evaluation method for portable, hand-held, U-healthcare medical devices. We reviewed current guidelines and standards for home-health devices from the Korea Food and Drug Administration (KFDA) and related international committees such as the ISO/IEEE and CE. We summarized the test methods and items for the evaluation of safety and performance related to U-healthcare medical devices from the above guidelines and standards. We defined requirements for a U-healthcare medical device to demonstrate good performance. In conclusion, we propose an evaluation method for U-healthcare medical devices, which will help improve the safety and reliability of these devices.

The purpose of this study is to provide the basic reference for appropriate ecological park planning through investigation and analysis of inviting environment of Suncheon Bay Ecological Park within the framework of 'universal design'. For this, investigating items were selected through literature reviews and legal standard of ecological park suggested by laws. Field survey on Suncheon Bay Ecological Park was conducted, The results suggesting analytical and practical implications are as follows. First, guided handles of any facilities were not equipped, so urgent supplementation is needed with legal standard of universal design. Especially, detailed criterion of universal design focusing on visitors' convenience should be reflected. Second, all facilities for the blind were not equipped and the floor height of entrance was also unsuitable. It implies that the disabled and the senior are restrained from doing independent activity, therefore, appropriate standard focusing on 'universal design' for the wide open activity space such as the park area should be re-provided. Finally, guidelines for applicable universal design of the activity space for the experience on the ecological park should be re-established.

In this study, the number of non-English speaking visitors is increasing day by day, and accordingly, there was a limitation in language communication and communication during radiographic examination. To this end, after distributing the handbook produced for inspection, the improvement effect of before and after explanation was examined. The score scale was not statistically significant as to whether it was the test site or not, and the degree of discomfort of the test, the degree of understanding of the breathing guidelines, and the satisfaction of the test description were improved and the score scale was improved before and after the description of the guide. Non-English-speaking foreign visitors were more satisfied with explanations in their own text than in English or Korean, and the method was also able to conduct effective inspections by informing the foreign guests when to control their breathing by using the lighting signals in the laboratory. In the future, the quality of medical services and imaging medical examinations can be improved only when communication methods are implemented from various perspectives, such as developing various language interpretation programs, developing guides for various test sites, and developing tools and improving foreign language skills of radiologists and medical staff. There will be. In the future, it may be used as a basic resource to prepare a manual that can be used to examine non-English speaking foreigners who do not understand English or Korean in other radiology labs.

Community Service Order is a program that holds a significant place in the system of probation. With its important role in the probation, there is an equally high expectation of the intervention from the program among the people which it serves. The problem lies in that people's understanding of the program is minimized to merely a volunteer-based social activity, which cause a division on how the program is to be run. The purpose of this research is to come up with a method that can efficiently organize the administrative plan to maximize its potentiality of the program. To adopt such a plan, "Sentencing to Service," an effective community service order program in Minnesota, U. S. A. was examined. An interview with the administrative staff, as well as a survey, using systematic sampling, with the participants was conducted to study the effective process and intervention of the program that has existed for fifteen years. The result concluded that "Sentencing to Service" is a successful program with the components of success being that of a positive support from the local community and high motivation level of the participants. In order for the program to be a positive experience for the participants, it is highly contingent upon the crew leaders. On the basis of the research findings, the following suggestions are made. First, a structured guideline for those who are involved in the program is necessary. Second, thorough training provided for the crew leaders are required and a social worker is recommended for the position of crew leader. Lastly, Community Service Order should not widen the net, but ought to serve as an alternative to incarceration.

The technique of information-communication rapidly developed has made it possible for us to do business through Internet. Electronic commerce was increased rapidly by the explosive development of the inter and communication revolution. E-Commerce has created a fundamentally new way of conduction and will change drastically accepted ways of doing business. Normally international trade has been formulated in a way that exporters and importers meet face-to-face and contract and pay by letter of credits. For the global electronic commerce to vitalized, the outstanding matters should encourage the creation of infrastructure of information security and new models in the field of electronic payment systems, electronic commerce agreement for remedy, adapting electronic date interchange in transport documents and negotiability of electronic bills of lading. The payment systems such as electronic fund transfers, tradecard system and electronic letters of credits issued by SWIFT system permit the parties concerned(sellers, buyers ad service providers) to settle payment electronically. Still they are many limitations for complete international electronic transactions. The following measures have to be taken to vitalize electronic trade transactions. It is needed to acquire information security such as authenticity, integrity, non-repudiation and confidentiality. All kinds of documents need to be replaced by electronic date exchange and the legal structure of international convention, national law for electronic payment systems have to be completed. Also a detailed guide of the banking operation and developing rules for electronic letters of credits need to be provided to adopt eUCP rules for the electronic presentation of documents.

The sensitivity analysis of input parameters was Performed fer an ingestion dose assessment model (U. S. NRC's Regulatory Guide 1.109 model) from routine releases of radionuclides. In this study, three kinds of typical Korean foodstuffs (rice, leaff vegetables, milk) and two kinds of radionuclides $(^{l37}Cs,\;^{131}I)$ were considered. The values of input parameters were sampled using a Latin hypercube sampling technique based on Monte Carlo approach. Sensitivity indices, which represent the influence or the importance of input parameters for predictive results, were quantitatively expressed by the partial rank correlation coefficients. As the results, the ratio of the interception fraction to the yield of agricultural plants and the human consumption rate were sensitive input parameters for the considered foodstuffs and radionuclides. Additionally, in case of milk, the transfer factor of radionuclides from animal intake to milk and the daily intake rate of feedstuffs were sensitive input parameters. The weathering removal half-life and the delay time from food production to human consumption were relatively sensitive for $^{137}Cs$ and $^{131}I$ depositions, respectively.
