The purpose of this study is to compare the differences in the subjective quality of life (QoL) perceived by residents in different settlement spaces such as urban vs. rural and Seoul Capital Area (SCA) vs. Non-Capital Area (NCA). Using the data of the 'Quality of Life Satisfaction Survey for Balanced Development' conducted nationwide by the Presidential Committee for Balanced National Development in 2018, a propensity score matching method was introduced to compare the differences between the types of settlement spaces. The results show that no significant difference is found between all the types in satisfaction with local life, and in the case of happiness, rural residents show a higher level than those living in cities. Looking at the quality of life by QoL domain, the QoL of urban residents in SCA is generally the highest in the basic living environment, medical care, and culture/leisure domains, while the QoL of rural residents in the job/income, environment, community, and welfare domains is higher than that of residents of SCA and NCA cities. Interestingly, in no domains NCA cities show their relative strength. These results show the value of rural areas in the face of increasingly prevailing urbanization trends, and suggests that the value of rural areas must be strengthened for rural development. It is necessary to pursue policy efforts such as rural regeneration based on spatial planning in order to respond to the disorganized development that damages the value of the rural environment and landscape and to harmoniously maintain and develop the rural settlement.

Parents' interest and care are very important for their children in the process of growing up, but parenting is also very unfamiliar and difficult for themselves. Parents constantly need information related to parenting, and in order to solve this problem, they try to obtain information through informal meetings or social relationships among parents at an individual level, which often brings up conflicts and stresses. Accordingly, the purpose of this study is to explore the characteristics of social networks among parents and to understand the influence of the network characteristics on information-sharing intention and information-sharing satisfaction. To this end, a survey questionnaire was developed based on previous studies and was administered among parents whose children are in a daycare center. Then, the data was analyzed using social network analysis (SNA) method. Findings indicate that the correlation among the social networks, the information -sharing intention, and the information-sharing satisfaction was significant, but the influence of the social networks on the information-sharing intention, and the information-sharing satisfaction was not established. It was also found that the intention to receive help was higher than the desire to help others. Policy suggestions to meet parents' information needs and the need to reconsider the role of local public libraries were presented.

In this study, the factors of major satisfaction(curricular satisfaction, class satisfaction, relationship satisfaction, cognitive satisfaction, and general satisfaction factors) which influence the employment preparation behaviors were identified by conducting a survey of female college students of the department of library and information science, and whether the feeling of employment efficacy had a moderating effect on the relationship between the the major satisfaction and the employment preparation behaviors were verified. The research results are as follows. First, curricular satisfaction(C.R.=3.847, p<0.001), class satisfaction(C.R.=3.244, p<0.01), relationship satisfaction(C.R.=3.045, p<0.01), and cognitive satisfaction(C.R.=2.464, p<0.05) factors turned out to have a significant positive(+) effect on the employment behaviors of female college students of the department of library and information science. Second, the moderating effect between the high group and the low group in terms of employment efficacy turned out to have a statistically significant moderating effect as the p value was less than 0.05, p = .040. The results of this study may be used as the useful basic data to not only improve the employment rate for the department of library and information science of community colleges in Korea, but also to prepare for the rapidly declining school-age population and the Institutional Accreditation.

The purpose of this study is to suggest a mid- to long-term expansion plan to resolve the blind spot and alleviate the imbalance of public library services in Daegu City. The research methods for this purpose included literature review, related laws and statistical data analysis, case study, and opinion survey. As a result, the first service area was set as a total of 14 areas based on administrative districts(Jung-gu, Seo-gu, Nam-gu, and Dalseong-gun each have one, Dong-gu and Buk-gu each have two, and Suseong-gu and Dalseo-gu have three each). Second, the expansion scenario for public libraries in Daegu City was proposed to add 26 libraries by the final target year (2032) based on the trend of national library growth over the past 13 years (2008-2020) and the forecast for the next 10 years (2023-2032). Third, the construction scenarios for each basic local government, excluding the Daegu representative library, are as follows: One library each in Jung-gu, Seo-gu, and Nam-gu; two libraries in Suseong-gu; three libraries in Dalseong-gun; four libraries in Dong-gu; and seven libraries each in Buk-gu and Dalseo-gu. In terms of floor area, it is proposed to add a total of 17 branch libraries with a minimum legal standard of 330-2,499㎡, four central libraries with 2,500-4,999㎡ each, and four central libraries with 5,000-9,999㎡ each. On the premise of these conditions, Daegu City and public libraries should focus on creating an inclusive and open community space, creating a digital platform, strengthening the library operation and cooperation system centered on Daegu representative library, developing collections and specializing services for local hub libraries, enhancing various knowledge information and program services, managing key library indicators and improving social contribution.

According to the 「Rural Spatial Reconstruction and Regeneration Support Act」, enacted on March 29, 2024, all local governments are required to establish a 'Rural Spatial Reconstruction and Regeneration Plan' (hereinafter referred to as the 'Rural Spatial Plan'). In order for the 'Rural Spatial Plan' to be appropriately established, this study analyzed the supply and demand of spatial data from the perspective of user stakeholders and derived implications for improving rural spatial planning data utilization. In conclusion, three key recommendations come from this result. Firstly, it is necessary to establish an integrated DB for rural spatial planning data. This can solve the problem of low awareness of scattered data-providing websites, reduce the processing time of non-GIS data, and reduce the time required to acquire data by securing the availability of data search and download. In particular, research should be conducted on the establishment of a spatial analysis simulation system to support stakeholders' decision-making, considering that many stakeholders have difficulty in spatial analysis because spatial analysis techniques were not actively used in rural projects before the implementation of the rural agreement system in 2020. Secondly, research on how to improve data acquisition should be conducted in each data sector. The data sector group with the lowest ease of receiving are 'Local Community Domain', 'Changes in Domestic and International Conditions', and 'Provision and Utilization of Daily Life Services'. Lastly, in-depth research is needed on how to raise each rural spatial planning data supply stakeholder to the position of player. Stakeholders of 'University Institutions' and 'Public Enterprises and Research Institutes' should give those who participate in the formulation of rural spatial plans access to the raw data collected for public work. Stakeholders of 'Private company' need to come up with realistic measures to build a data pool centered on consultative bodies between existing private companies and then prepare a step-by-step strategy to fully open it by participating various stakeholders. In order to induce 'Village Residents and Associations' stakeholders to play a leading role as owners and producers of data, personnel should be trained to collect and record data related to the village. In addition, support measures should be prepared to continue these activities.

Background: The aim of this study was to examine the association between physical activity and periodontitis in the Korean population. Methods: This study utilized data from 9,191 participants of the Korea National Health and Nutrition Examination Survey. Periodontitis was defined as a CPI score of 3 or 4. Physical activity was assessed by the trained interviewer using the International Physical Activity Questionnaire-Short Form (IPAQ-SF). IPAQ-SF is composed of vigorous physical activity, moderate physical activity, and walking activity. Multivariable logistic regression analyses and stratified analyses by obesity were performed. All analyses were conducted separately for males and females. Results: Females who engaged in vigorous and moderate physical activity had a 28% (OR = 0.72, 95% CI = 0.54 - 0.95) and 34% (OR = 0.66, 95% CI = 0.44 - 0.98) lower risk of periodontitis, respectively. In obese females, moderate physical activity in obese had a 65% lower risk of periodontitis (OR = 0.35, 95% CI = 0.18 - 0.67). Conclusions: Our findings suggest that moderate-intensity physical activity was inversely associated with a lower risk of periodontitis. In obese females, moderate physical activity had an independent inverse association with periodontitis.

This study examines popular entertainers' professionalism with division of genres and cast portions. While genres can be divided into TV drama and variety show, cast portion into leading, supporting, and minor role. Entertainers' thought is categorized into their professional consciousness and their program awareness. By this division and categorization, this study grasps concretely how genres and cast portions affect entertainers' ideas. We conducted a survey on one hundred entertainers in TV dramas and variety shows and have analyzed data by using n-way ANOVA. This study also conducted in-depth interview as a research method by which we intended to enhance validity of the result. The results provide that genres and cast portions affected on entertainers' professional consciousness and their program awareness. In terms of professional consciousness, significant result was drawn on thoughts of discrimination, community, vocation, and satisfaction. In terms of their program awareness, affection, accountability, ownership, and anxiety consciousness were significant. With this result, this study provides implications both theoretical aspect and practical aspect. On theoretical aspect, this study broadens celebrity studies beyond star studies, and attempts to categorize entertainers theoretically. On practical aspect, it provides reconsideration on broadcasting condition, and suggests solving the problem of gap among entertainers.

This paper empirically analyses patterns of time allocation of the elderly, examining economic participation and volunteer work or social activities under the assumption that such activities have positive effects not only on the individuals and on the local communities but also on the society as a whole. As the result of descriptive analysis on the Korean Time Use Survey 1999, 2004 and 2009, the adults aged 60 to 64 years decrease time for paid work rapidly while increase time for passive leisure comparably slowly. In terms of time for active leisure, they devote less time to volunteer work and social activities, however, more time to self-centered activities such as education, cultural events, sport and fitness, and religious work. The overall pattern of decrease in time on economic or social participation for the elderly appeared be more significant in the birth cohorts of the early 1940s than those born in the late 1930s. The analysis implies that it is necessary for the government to encourage them to participate in community activities, either economic or social, with necessary policy responses. The result of the Tobit analysis on the dependent variables of each type of the 6 leisure activities demonstrated the self-centered active leisure time has increased over the last decaseds, whose pattern appeared to be more strengthened when the proportion of the elderly with higher education has increased.

The aim of this study was to investigate differences in the achievement standards from the 2015 to the 2022 revised national science curriculum and to present the implications for science teaching under the revised curriculum. Achievement standards relevant to primary science education were therefore extracted from the national curriculum documents; conceptual domains in the two curricula were analyzed for differences; various kinds of centrality were computed; and the Louvain algorithm was used to identify clusters. These methods revealed that, in the revised compared with the preceding curriculum, the total number of nodes and links had increased, while the number of achievement standards had decreased by 10 percent. In the revised curriculum, keywords relevant to procedural skills and behavior received more emphasis and were connected to collaborative learning and digital literacy. Observation, survey, and explanation remained important, but varied in application across the fields of science. Clustering revealed that the number of categories in each field of science remained mostly unchanged in the revised compared with the previous curriculum, but that each category highlighted different skills or behaviors. Based on those findings, some implications for science instruction in the classroom are discussed.

We conducted a field survey from 2018 to 2020 to analyze the spatial distribution of phytoplankton communities at 13 stations in the East Sea. The diatom Chaetoceros curvisetus appeared as the dominant species in winter, and small flagellates less than 20 ㎛ prevailed in all seasons except winter. The seasonal average range of the micro (>20 ㎛), nano (20 ㎛≥Chl-a>3 ㎛), and picophytoplankton (≤3 ㎛) was 20.6-26.2%, 27.1-35.9%, and 40.8-49.0%, respectively. The composition ratio of nano and picophytoplankton was high at the surface mixed layer from spring to autumn when the water columns were strongly stratified. Especially, the stability of the water mass was increased when the summer surface water temperature was higher than that of the previous year. As a result, the nutrient inflow from the lower layer to the surface was reduced as the ocean stratification layer was strengthened. Therefore, the composition ratio of nano and picophytoplankton was the highest at 77.9% at the surface mixed layer. In conclusion, the structure of the phytoplankton community in the East Sea has been miniaturized, which is expected to form a complex microbial food web structure and lower the carbon transfer rate to the upper consumer stage.
