A total of 262 bacterial strains were isolated from clay minerals, bentonite and zeolite, in Gyeongsangbukdo, Republic of Korea, and their hydrolytic enzyme activities were analyzed. Most of the isolated strains belonged to Micrococcales and Bacillales order. Of strains, 96 strains produced α-amylase activity, 42 strains showed cellulase activity, 111 strains had pectinase activity, and 70 strains showed protease activity. Among them, 177 isolates exhibited one or more of the hydrolytic enzyme activities and in particular Bacillus cereus MBLB1321, B. albus MBLB1326 and KIGAM017, B. mobilis MBLB1328, MBLB1329 and MBLB1330 showed all of the enzyme activities. These results demonstrate the diversity of functional Bacillus species in clay minerals as vital sources for the discovery of industrially valuable hydrolytic enzymes, which have a great commercial prospect in various bio-industrial applications.

Unmet healthcare is an important indicator for measuring accessibility of healthcare services. We analyzed the following four data from a nationally representative sample of South Korean population: Korea Health and Nutrition Examination Survey (KNHANES, 2007-2021), Community Health Survey (CHS, 2008-2021), Korea Health Panel Survey (KHP, 2011-2019), and Korean Welfare Panel Study (KOWEPS, 2006-2021). The proportion of individuals reporting unmet healthcare needs were 6.0% (KNHANES), 5.1% (CHS), and 13.1% (KHP). Annual percentage change (APC) which identifies trend for the follow-up period was -9.4%, -9.4%, and -5.3%, respectively. The proportion of individuals reporting unmet healthcare needs due to cost were 1.2% (KNAHANES), 0.5% (CHS), 2.7% (KHP), and 0.4% (KOWEPS). The APC was -10.4%, -16.1%, -11.5%, and -19.1%, respectively. Compared to the previous year, the rate of unmet healthcare needs decreased slightly, but the rate of unmet health care needs due to cost tended to increase. Overall, higher rates of unmet healthcare needs were reported in the low-income and the elderly population. Although it was confirmed through the APC that the rate of unmet healthcare experience has decreased over the past decade, it can be seen that there is still a disparity by income level and age. These results suggest the need for an appropriate health benefit coverage policy for the low-income and the elderly.

Purpose: Since the establishment of Korea Society for the Study of Hospital Architecture, Korea Institute of Healthcare Architecture have carried out various activities to improve the level of healthcare architecture in Korea. Despite of more diverse activities than the beginning, the history and activities of early days of the Society and Institute could be forgotten and omitted. So this paper aims to describe accurately the process of establishment of Korea Society for the Study of Hospital Architecture and Korea Institute of Healthcare Architecture and the activities of the Society and Institute. Methods: Publications and documents issued by Korea Society for the Study of Hospital Architecture and Korea Institute of Healthcare Architecture have been surveyed. And to identify the unwritten activities, personal memo and interviews were also used. Results: The result of this study can be summarized into two points. The first one is that some of the unwritten and uncertain history and activities of the beginning of the KIHA could be identified. The second one is that not also the activities of Korea Society for the Study of Hospital Architecture and Korea Institute of Healthcare Architecture but the activities prior to the Society for the Study could be described. Implications: This research could be the basic data to arrange the history and activities of KIHA.

Purpose: This study was done to identify the impact of physical activity on healthcare utilization among Korean adults. Methods: Drawing from the 2008 Korean National Health and Nutrition Examination Survey (NHANES IV-2), data from 6,521 adults who completed the Health Interview and Health Behavior Surveys were analyzed. Association between physical activity and healthcare utilization was tested using the $X^2$-test. Multiple logistic regression analysis was used to calculate the odds ratios of using outpatient and inpatient healthcare for different levels of physical activity after adjusting for predisposing, enabling, and need factors. A generalized linear model applying a negative binomial distribution was used to determine how the level of physical activity was related to use of outpatient and inpatient healthcare. Results: Physically active participants were 16% less likely to use outpatient healthcare (OR, 0.84; 95% CI, 0.74-0.97) and 23% less likely to use inpatient healthcare (OR, 0.77; 95% CI, 0.63-0.93) than physically inactive participants. Levels of outpatient and inpatient healthcare use decreased as levels of physical activity increased, after adjusting for relevant factors. Conclusion: An independent association between being physically active and lower healthcare utilization was ascertained among Korean adults indicating a need to develop nursing intervention programs that encourage regular physical activity.

The concept of Health Related Quality of Life and its determinants have evolved since the 1980s. Although many researchers have published articles of technology usage in hospitals and the installation of technology based healthcare system, the research about applying the information technology to improve the patients' perceived quality of healthcare services is still limited. In general, services are deeds, processes and performances that are essentially concerns of the consumer. The healthcare service quality depends on tangible factors, such as equipments, facilities, and the quality of hospital staff and also the intangible ones. The main purpose of this work is to establish new model and find out the contribution of information technology to enhance the patients' perceived quality of healthcare service. We attempted to examine the main information technology related factors in 3 aspects, namely quality of information, the technology accessibility and the community that can improve patients' perceived quality of healthcare services. Offline and online questionnaires were used to measure the patients' perceived quality and were distributed to 384 people in 2 countries, Laos and South Korea. A principle component analysis and multiple regressions were used to verify our model. Results show that the use of information technology has partial positive effect on patient-physician interaction in both countries. However, patient knowledge and patient autonomy which are the 2 dimensions of patient-physician interaction has significant positive effect on patients' perceived quality of healthcare service.
