The need for network protection, accounting and resource management in foreign administrative domain requires appropriate security services. In this paper, we propose an access control protocol to support the authentication between mobile node and visiting subnet. Our hybrid way of approach aims to reduce computational overhead and minimize the use of network bandwidth. We also propose non-certificate based public-key cryptography to provide non-repudiation, which does not require CRL retrieval and certificate validation.

This paper describes how to derive audit criterion, audit domain, detail technology, and functional check items which are core of hospital information system, consisting of OCS, EMR, and PACS. Using the check items listed above, we investigated the objective validity for the construction audit of hospital information system. As a result, the derived audit criterion, audit domain, detail technology, and functional check items were verified as check items for audit. Since using the current audit check items of public area is insufficient to construct efficient, reliable, and stable hospital information system, we suggest adopting the hospital information system audit area, audit check items, and process that are presented in this paper.

We present our experiences with open-source spatio-temporal database systems for managing and analyzing big astronomical data acquired by wide-field time-domain sky surveys. Considering performance, cost, difficulty, and scalability of the database systems, we conduct comparison studies of open-source spatio-temporal databases such as GeoMesa and PostGIS that are already being used for handling big geographical data. Our experiments include ingesting, indexing, and querying millions or billions of astronomical spatio-temporal data. We choose the public VVV (VISTA Variables in the Via Lactea) catalogs of billions measurements for hundreds of millions objects as the test data. We discuss issues of how these spatio-temporal database systems can be adopted in the astronomy community.

This brief report aims to establish the keyword content of studies on occupational health and safety-the key framework of the world of work in the trade and health domain. Data were collected from the SCOPUS database, focusing on articles on occupational health and safety and related keywords, with an emphasis on abstracts and titles. Data were analyzed and summarized based on keywords included from the MeSH database. There were 24,499 manuscripts in the domain and 1,346 (5.40%) occupational health-related keywords, including those that overlapped. The most frequently referenced occupational health-related keyword was "occupational health" (452 articles), followed by "occupational safety" (141 articles). There were fewer keywords on occupational health in the trade and health literature. As the world of work has been prioritized because of the recent new normal of work life since the COVID-19 pandemic, examining the focus of occupational health priorities within the global perspective is crucial.

Covid-19 posed a serious threat to public health worldwide, especially in the absence of vaccines or medicines. The only viable strategies to combat a virus with a high infection rate were to apply lock-down strategies, transport ban, social and physical distancing. In this work, we provide a domain-specific component model for crisis management. The model allows for building a plan for managing Covid-19 crisis and use the plan as a template to generate a system specific for managing that crisis. The crisis component model is derived from X-MAN II, a generic component model that we have developed for the aircraft industry

With the increase in copyright content exports to overseas markets due to the recent globalization of the Korean culture, the added value of the Korean digital content market is increasing at a significant rate. As such, as the size of the copyright market increases, different piracy sites have emerged that generate profits by illegally distributing works without the permission of the copyright holders, resulting in direct and indirect damage to these copyright holders. The existing copyright detection methods used in public institutions for solving this problem are limited, while the piracy sites are ever-changing. Methods are being continuously developed to achieve better detection results. To this end, it is possible to detect the latest infringement site domain by detecting the infringement site domain that is constantly changed through the search engine. This paper proposes an improved piracy site detection method using a search engine to prevent the damage caused by piracy sites.

This study was aimed at comparing and evaluating one main role, the professional self concept and job satisfaction of public health nurses and clinical nurses. Method: The data was collected from 72 nurses in 8 health centers and 86 nurses in 5 hospitals in Daegu city and Kyungpook province from May 5th to June 5th, 2001. This study was interviewed by trained social workers. The origin of questionnaires used in this study were PSCNI(Professional Self-Concept of Nurses Instrument) to measure the professional self concept of nurses and JDI(Job Descriptive Index) to measure the job satisfaction of nurses. The data was analyzed by SAS(version 6.12) and statistical methods used were Chi-square test, t-test, ANOVA(analysis of variables) and ANCOVA(analysis of covariate). Result: The findings of this study were as follows: 1. The most important domain in the main role of public health nurses were as counsellors, managers, mediators and evaluators. In clinical nurses, their main roles were, directors of nursing, researchers, spokesmans, and informers. 2. Public health nurses showed lower scores in the professional self concept of nurses than clinical nurses, what statistically significant tool was used to suggest this finding. 3. Public health nurses showed higher scores in job satisfaction than clinical nurses, but again, explain the tool used in these findings for give a rationals. 4. For public health nurses, general characteristics which affected professional self concept were age, educational level, and duration of job. In clinical nurses, the general characteristics which affected professional self concept were age, religion, marital status, and duration of job. 5. For public health nurses, there was no general characteristic which affected job satisfaction. In clinical nurses, the general characteristics which affected job satisfaction were age, religion, and duration of job. Conclusion: Nursing profession should give a training to competent nurses who can deliver high quality care to meet the needs of health consumers. The role of nurses has been expended and specialized as health conception has been changed in Korea.

The purpose of this study was to improve the academic achievement at the public practical center of technical high school in Busan. For this study, 1 class(31 students) in the second grade at "B"technical high school were selected and these students were divided into two groups. One is the experiment group which blended learning was applied to and the other is control group which traditional lecture method was applied to. Each group was divided into three sub-groups by the level of learning ability. Non-randomized control-group pretest-posttest design was applied for this experiment planning. The subject of experiment was the unit of "3D Modeling and Making NC code" in the textbook of "Application of Automatic System" applied by the public practical center of technical high school in Busan. On-line contents were developed and applied to the blended learning to control group. In order to analyze the test result, t-test with a significance level of 0.05 was carried out using SPSS 10.0. The results of this study was summarized as follows; First, as a result of the post test performed on the experiment and the control group, there was a significant difference between two groups, that was, the blended learning was more effective than the traditional lecture method in improving academic achievement. Second, blended learning was more effective than the traditional lecture method in the group of high-leveled and middle-leveled, but was little effective on the low-leveled group. Third, blended learning was more effective than the traditional lecture method in the functional domain, but was little effective in the cognitive domain and psychomotor domain.

Copyright is a legal criterion for determining the scope and method of digital library service. Works with expired protection periods correspond to the public domain and can be freely used by anyone. For this reason, it is a priority consideration in digital library construction and services. The purpose of this study is to examine how actively libraries are using expired protected works for digital library services. To this end, the relevant provisions of the Copyright Act applied to the construction and service of digital libraries were first summarized, and the meaning of the copyright protection period was theoretically examined. The current status of online services for expired works by the National Library of Korea was examined, focusing on the works of three Japanese colonial era writers, Kim Yoo-jung, Lee Hyo-seok, and Chae Man-sik, to check the specific service status of expired works. It reveals that the National Library of Korea is not fully utilizing the scope of the law, and that this situation is linked to the rights of other authors included in the book. Based on these results, it suggests that there is a need to change the service unit to focus on copyrighted works and to use authority records to systematize the management of authors' death years.

Objectives: This study aimed to evaluate the primary care quality of a public health center in a rural area using the Korean Primary Care Assessment Tool (KPCAT). It also examined some methodological issues in applying the KPCAT and interpreting its results. Methods: Seventy-nine patients who had visited their doctor more than four times responded to the KPCAT questionnaire. Descriptive statistics and a radar chart were used in analyzing data. Sign test was used to test the KPCAT score difference by don't know option scoring methods. Results: Median and interquartile range of the public health center's KPCAT scores were forty-five and sixteen points, respectively. Only the median of the first contact domain reached the expected value of seventy-five points. The proportions of those who scored under the expected value were under fifty percent in two of four comprehensiveness items, all of three coordinating function items, two of five personalized items and all of four family/community orientation items. There were some methodological issues including, how to score don't know option and make sure response scale consistency. Conclusions: There was much room to improve the primary care quality of the rural public health center. Especially, improvement is needed in the domain of coordinating function and family/community orientation. We also hope that methodological improvement of the KPCAT contributes to more valid and reliable primary care assessment.
