Thanks to KMTNet's wide field of view, it is time to implement imaging survey of extensive area of clusters of galaxies in the southern sky with modern instrument. As part of potential long-term survey of nearby (D < 50 Mpc) well-known clusters of galaxies, we propose a wide-field and deep survey of Fornax cluster as a first step of the project. By imaging the 400 square deg region (100 fields) enclosed within the five times virial radius of the Fornax cluster, in three SDSSfilters(g', r', i'), we can provide an unprecedented view of structure of Fornax cluster using sample from giant to dwarf galaxies. We will secure galaxies with brightness comparable to the limiting magnitude (r'=23.1 AB mag) of SDSS. Furthermore, we also request extremely deep (limiting surface brightness of ~ 28 mag $arcsec^{-2}$forr'band) survey for the central region (16 square degree, i.e., four fields) of Fornax cluster. This will allow us to detect the diffuse intracluster light (ICL) that permeates clusters as a valuable tool for studying the hierarchical nature of cluster assembly. In order to complete whole survey, about 285 hr observing time (without overhead) is required. By combining data available at other wavelengths, it will offer unique constraints on the formation of large-scale structure and also provide important clues for theories of galaxy formation and evolution. Our proposed survey will be implemented in the close collaboration with researchers in various countries (Germany, Australia, UK, USA) and ongoing project (e.g., SkyMapper).

This study aims to investigate the awareness and needs of patients as consumers and therapists as providers on the introduction of home physical therapy in the long-term care insurance. The survey participants were 96 patients and 132 physical therapists to a questionnaires, we analyzed for frequency of each questionnaire about awareness and necessity. As a result of the test, they considered that physical activity support services provided by nurse and nurses aid ware not specialized enough(pt 60,4%, PT 75,4%) and quality therapy should be available through a home physical therapy(pt 47.9%, PT 59.2%). Also, patients responded that the priorities to improve long-term care insurance were given to lowering expenses(35,4%) and expanding coverage of subjects(32.3%) while the physical therapists responded that professionals should be expanded(73.8%) and diverse rehabilitation services(20.2%) and a rehabilitation team should be introduced. They responded that the reasons of home physical therapy were needed that it was hard for patients to visit medical centers(PT 30.0%) themselves and it would be improvable for them to get physical function in elderly(pt 47.1%) through the service. In conclusion, as most patients as well as physical therapists responded that home visit therapy services should be introduced and their awareness of it was very high, it is suggested that the service should be quickly introduced as soon as possible.

The research was based on long-term studies on the major physico-chemical and hydrological factors and zooplankton community dynamics in the Hwang River. We had 341 times survey and collected zooplankton samples in the Hwang River of mid-Nakdong River from 1995 to 2013. We identified 97 zooplankton species, including 77 rotifers, 16 cladocerans, and 4 copepods. The total zooplankton abundance and species diversity were shown distinctive temporal variation (ANOVA, p<0.001). Annual average of zooplankton population density was 58.4±3.2 ind L^-1 (n=341) and the lowest was 17.0±3.8 ind L^-1 (1996, n=20), while the highest was 151.5±32.3 ind L^-1 (2010, n=22). For zooplankton, small rotifer groups(e.g., Keratella sp., Brachionus sp., Trichotria sp.) dominated the study site for 19 years survey. Statistical analysis revealed that there were positive relationships with SiO₂ (p=0.002) and water level (p<0.001) for the high abundance of rotifer community. There were considerable variations both the total cladocerans population and the number of cladocerans' species concerning annual precipitation. Despite the appearance of various zooplankton in the Hwang River, the mean population density remained low. Due to the lateral structures in the Nakdong River, the downstream basin of the Hwang River is inevitably affected. The zooplankton community in our study site is considered to be mainly influenced by external factors that can stably increase and maintain the volume of the water body and internal factors that induce an increase in food sources through the inflow of nutrients into the water body.

The government and public institutions are conducting public-opinion surveys as means of drawing the scientific policy decisions throughout the country's whole sectors ; society, culture, welfare, education, etc. The Government Survey Data have been under management by each governmental department, but the improper ways of data collection and management have led to omissions and losses of some data. Also there are limitations on the statistic usage and access to the data due to the fact that the data are managed dispersedly in the form of printed materials. Accordingly, to make the survey data available for the long-term preservation and usage, this study suggests collection policy, standard of evaluation, metadata, the procedure and method of converting materials, preservation format.

Background: This study examined the public's perceptions of repeat dispensing as one of the measures to reduce the harmful effects of long-term prescriptions in Korea. Methods: From January 11 to 25, 2021, an online survey was conducted for adults using convenience sampling. A self-developed questionnaire was used. Results: There were 310 respondents, of which 228 (73.5%) preferred repeat dispensing. When considering the additional fee payment, 188 (60.6%) preferred repeat dispensing, and 54 (67.5%) out of a total of 80 chronic disease patients preferred it. It was confirmed that there was a difference in the willingness to repeat dispensing considering the additional cost depending on whether the patient had a chronic disease and the distance from home to the nearest pharmacy. As a result of subgroup analysis for patients with chronic diseases, frequency of outpatient visit, number of prescription days, method of packaging pharmaceuticals, and distance from home to the nearest pharmacy were identified as variables that could well predict the willingness to repeat dispensing considering paying additional fees. The preference for repeat dispensing may vary depending on conditions such as additional cost range, frequency and period of prescription use, disease and patient characteristics, so a careful approach is necessary. Conclusion: It is necessary for the government to consider the introduction of repeat dispensing with interest in the public demand.

This study aimed to examine the predictors of mental health confidence(MHC) among individuals in psychiatric long-term care facilities(PLCF). It further examined whether the predictors and underlying mechanisms differed by the length of hospitalization. Sample consisted of 1,742 individuals residing in PLCF who participated in the Survey on PLCF. Structural equational modeling was used to examine the predictors of MHC. Multi-group Structural Equation Modeling(SEM) was used to examine whether the predictors and mechanisms differed by the length of hospitalization between those of 10 years or less (n=962) and 10 years and more (n=780). Major findings were as follows. (1) Education, duration of mental illness, and psychiatric symptoms were significantly related to MHC. (2) Duration of mental illness presented significant indirect effects on MHC via its effects on perceived stigma. (3) The predictors and underlying mechanisms differed by the length of hospitalization. Based on the findings, implications and limitations of the research were discussed.

This study analyzes the effects of life course events and labor market conditions on the duration of career interruption among Korean women. The data were drawn from 'A Survey on the Women's Employment Interruption in Korea' conducted by the Korean Ministry of Gender Equality in 2009(currently the Korean Ministry of Gender Equality and Family). This study categorizes the duration of career interruption into three categories: (1) short term interruption(less than 12months), (2) short-medium term interruptio(12-35 months), (3) intermediate term interruption(36-59 months), (4) long term interruption(longer than 36 months), and then analyzes how demographic factors, labor market condition, and life events shape the timing of re-entry into the labor market among women. According to the findings, the jobs that are conducive to combining market work and mother's role expedite women's return to the labor market. Further, the younger, higher the level of human capital, and higher monthly wages that women earned before leaving the labor market, women are likely to experience short-term interruption(less than 12 months) rather than long-term interruption(longer than 60 months). Women who left from the labor market to care for kids are also likely to return to the labor market. However, women who have preschoolers are likely to experience long-term career interruption. These findings highlight the role of family supportive culture at the workplace in order for women to continue their employment while intensive family formation period. Furthermore, the finding that the discriminatory practices against women, in particular mother workers at the workplace lead women to exit from the market work calls for attention to establish family friendly workplace.

The current study initiated from an action-plan level perspective of revitalizing Green IT (Information Technology) in Korea by building a standardized national Green IT brand. In order to setting up a national level brand, there should be a big quantitative survey for identifying Green IT brand concepts. For this, the current study provides exploratory research results based on preliminary interviews and literature survey before the quantitative survey. The present article suggests a research framework and describes important factors for setting up a national level Green IT brand. In-depth interviews with panels were executed and existing Green IT brands in other countries are summarized and asked for evaluation to a small number of panels. The research results show that (1) National level Green IT brand should include wider concepts of IT, (2) Green IT brand will be more appealed by the public when it is simple, straightforward, and intuitive, (3) Earth, Tree, and/or Water show higher correlation with Green IT concepts. Green IT brand will offer marketing promotion effects to companies who adopt national level Green IT brand as well as increase public use of Green IT in daily life. For this reason, Green IT brand will be a win-win strategy and this should be cared and executed by the related government agencies with long term perspective.

Stars form through the gravitational collapse of molecular clouds. However, the rate at which a star gains most of its mass and the physics that drives the main phase of stellar growth is still unclear. The typical luminosity of observed protostars is smaller than what expected from the Shu's inside-out collapse model, which predicts a constant mass accretion rate. The episodic accretion model has been suggested as a solution of this luminosity problem. The JCMT Transient survey is a long term monitoring program using JCMT/SCUBA-2 to detect accretion variability of protostars in the eight nearby star-forming regions. Recently, we found a rise of the 850 micron flux at a clump in the Serpens main region at the rate of ~17% relative to the mean flux over previous observations. The submm clump is associated with a class I protostar, EC53, which has been reported as a binary system with a periodic variability. In this talk, we will provide a brief overview of the JCMT Transient Survey project, present the detection of the variable source, and discuss about follow-up observations.
