Background: Socioeconomical disadvantaged communities are more vulnerable to environmental chemical exposure and associated health effects. However, there is limited information on chemical exposure among vulnerable populations in Korea. Objectives: This study investigated chemical exposure among underprivileged populations. We measured urinary metabolites of phthalates in urban disadvantaged communities and investigated their correlations with residential environment factors and relative socioeconomic vulnerability. Methods: Urine samples were collected from 64 residents in a disadvantaged community in Seoul. A total of eight phthalate metabolites were analyzed by liquid chromatography-mass spectroscopy. Analytical method used by the Korean National Environmental Health Survey (KoNEHS) was employed. Covariate variance analysis and general linear regression adjusted with age, sex and smoking were performed. Results: Several phthalate metabolites, namely monomethyl phthalate (MMP), monoethyl phthalate (MEP), mono-(2-ethyl-5-hydroxyhexyl) phthalate (MEHHP), and mono-n-butyl phthalate (MnBP) had higher levels than those reported in the adults of 4th KoNEHS. Notably, the MnBP level was higher in the lower socioeconomic group (geometric mean [GM]=47.3 ㎍/g creatinine) compared to non-recipients (GM=31.9 ㎍/g creatinine) and the national reference level (GM=22.0, 28.2 and 32.2 ㎍/g creatinine for adults, 60's and 70's, respectively.). When age, sex and smoking were adjusted, MEP and MnBP were significantly increased the lower socioeconomic group than non-recipients (p=0.014, p=0.023). The lower socioeconomic group's age of flooring were higher than non-recipients, not statistically significant. Conclusions: These results suggest that a relatively low income and aged flooring could be considered as risk factors for increased levels of phthalate metabolites in socioeconomic vulnerable populations.

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.

Recently, the domestic plant disease control policy for fire blight has been implemented partial control in addition to burial control. In this study, an on-site management survey was conducted targeting orchards that implemented partial disease control from 2019 to 2020 in order to find efficient implementation methods for partial disease control. As a result of an investigation into 22 pear and apple orchards in Cheonan and Chungju, 7 orchards were buried. The upper part of the cut infected plants was burned at 16 orchards and covered with plastic vinyl after lime treatment at 6 orchards. The lower stumps of cut infected plants were burned at 7 orchards and covered with plastic vinyl after lime treatment at 15 orchards. There were two orchards where suckers appeared on the stumps even though covers were applied. There was no infection by Erwinia amylovora in the suckers. The conservation condition of lime treatment was good, but warning signs were absent at 6 orchards. Most orchards treated the stumps and surrounding areas with glyphosate-isopropylamine herbicide. The effect of partial control was judged to be safe.

Universities that previously targeted in 20s have recently diversified their operation methods, founding purposes, and target. With a significant decrease in the school-age population relative to the number of universities, universities are making their best efforts to secure new students and minimize student attrition. In this study, an online survey was conducted to empirically examine the effects of motivation for major selection and sense of belonging on learning persistence intention among students in beauty-related departments at 2-year and 4-year general universities and cyber universities. The collected data from 119 students at general universities and 113 students at cyber universities were analyzed using SPSS 28. The key findings can be summarized as follows: For general universities, motivation for major selection did not have a significant effect on learning persistence intention, but sense of belonging had a significant positive effect. Additionally, an interaction effect was observed, indicating that as the sense of belonging increased, extrinsic motivation significantly increased learning persistence intention. For cyber universities, intrinsic motivation and sense of belonging among motivations for major selection had a significant positive effect on learning persistence intention, while the moderating effect of sense of belonging in the relationship between motivation for major selection and learning persistence intention was not significant. In summary, for general universities, the factor that influenced students' learning persistence intention was a sense of belonging to the university, while for cyber universities, intrinsic motivation played a significant role. These findings are expected to provide meaningful insights and data for universities to develop effective policies for preventing student attrition.

This study was conducted for a systematic literature review according to the period, subject, and research method for 198 papers related to tattoo and semi-permanent makeup published from 1979 to 2022. By period, it was divided into the first period (1979-1994), the second period (1995-2005), the third period (2006-2012), and the fourth period (2013-2022). In the first period, research on health and medical aspects was the main focus, and in the second period, studies in various aspects such as art and culture began to appear. The 3rd period was characterized by increased research on semi-permanent makeup, and the 4th period was marked by a rapid increase in research on tattoos and semi-permanent makeup. By research topic, it was analyzed by dividing it into health and medical care, beauty, fashion and art, society and culture, law and system. As a result, cosmetic studies were most actively conducted to identify consumers' preferences and perceptions, and health and medical studies were the second most common. Recently, as the need for legalization has increased, studies related to laws and systems have increased rapidly, and studies on culture, history, and fashion have also been conducted. By research method, survey research were used the most, and various methods such as literature study and case studies were also used. This study is expected to further promote follow-up research in the future and contribute to the development of related industries.

Background: The purpose of the study was to investigate the level of infection control and prevention awareness among dental practitioners in Korea based on the infection control and prevention guidelines of the Centers for Disease Control and Prevention (CDC) in the United States. Methods: A survey was created on 'Standard and Education on CDC Infection Control Standards', 'Matters related to CDC Infection Control Prevention', and 'Characteristics of Research Subjects and Infection Control Characteristics' based on the CDC Dental Infection Control List.' A total of 222 surveys were conducted and used for frequency and cross-tabulation analyses. Results: Most research participants worked at university or general hospitals, and 93.7% had received infection prevention education within the past year. The average awareness of the CDC dental infection control standards and education was 77.2 %, which was higher than previous research results. Preventive awareness was 71.5% on average, and there was a statistically significant difference in preventive awareness between the certified and non-certified evaluation groups (p<0.001). Conclusion: The participants of this study showed a higher awareness of infection control standards, education, and prevention than those in previous studies. However, this was insufficient compared with the CDC dental infection control standard prevention guidelines. Therefore, government agencies and related organizations must establish systematic infection control systems.

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.

Background: This study was aimed at investigating factors influencing the selection of dental institutions for implant surgery among young adults (age: 20-64 years) and identifying differences in these factors according to general characteristics. Methods: We conducted an internet survey for approximately 2 months, from April to July 2022, and analyzed data from a total of 128 people. Dental institution selection factors included three items of convenience of transportation, five items of physical environment, three items of image of institution, five items of image of dental staff, five items of dental service, and four items of basic dental elements. The importance score for each item was investigated on a five-point scale. Results: The importance score for each dental institution selection factor was the highest for dental service (4.42 points), followed by basic dental element (4.00 points), physical environment (3.89 points), image of institution (3.81 points), convenience of transportation (3.76 points), and image of dental staff (2.78 points). The importance score for each item was the highest for dentists' technique, followed by cleanliness, reliability, and dentists' attitude. Women had higher average scores for all factors compared to men, with statistical significance in scores for convenience of transportation, physical environment, image of institution, dental service, and basic dental elements (p< 0.05). Conclusion: To attract patients seeking implants to a dental institution, attention should be paid to the patients' institution selection factors. In addition, the environment of a dental institution should be created in such a way that it favors patients' selection factors.

Background: Dental hygienists emphasize the ethics of healthcare workers. To effectively cope with various ethical conflicts, it is necessary to establish a reasonable ethical value system. Therefore, this study intends to use basic data to develop ethics education programs and ethical value evaluation tools. Methods: We conducted a questionnaire survey targeting dental hygienists between January 1 and 15, 2023. A total of 251 people's responses were analyzed with SPSS Win 25.0, to perform frequency, t-test, one-way ANOVA, and multiple regression analysis. Results: The idealistic propensity (3.82 points) was higher than the relativistic propensity (3.42 points), and the absolutists showed a deontological position in the partnership area and dental hygiene work relationship area(P < 0.001). Regression analysis of factors affecting ethical values revealed that idealism (β=,444, p=0.000), marital status (β=-0.123, P = 0.035), and position (β=-0.154, P = 0.009) were significantly related to ethical propensity. Conclusion: It is necessary to develop an ethics education program that considers the ethical propensity of dental hygienists and establish firm ethical values by implementing situation-oriented ethics education that can respond to many changes and conflicts.

Purpose : This study sought to determine the influence of nursing students' self-leadership, empathic ability, and depression on their interpersonal skills. Methods : This study applied a descriptive survey research design involving a self-report questionnaire. The participants were 315 nursing students in B city. Data were collected from April 27 to May 6, 2022. The data were analyzed using the percentage, mean, standard deviation, t-test, ANOVA, Scheffé test, Pearson's correlation coefficients, and multiple regression with IBM SPSS/WIN 23.0 program. Results : The participants' self-leadership score was 3.63±.65, their empathic ability score was 3.35±.40, their depression score was .84±.50, and their interpersonal skills score was 3.64±.80. Among the sub-categories, others' temperament scored the highest at 3.70±.86, followed by communication at 3.67±.86 and promoting relationships at 3.53±.86. Interpersonal skills were positively correlated with both self-leadership (r=.48, p<.001) and empathic ability (r=.33, p<.001). Self-leadership was positively correlated with empathic ability (r=.17, p<.05), but, negatively correlated with depression (r=.27, p<.001). The multiple regression analysis revealed, that the factors with the most significant effect on promoting relationships were, in descending order, self-leadership (β=.49, p<.001), empathic ability (β=.19, p<.001), and gender (β=.10, p=.033); the factors affecting others' temperament were, in descending order, self-leadership (β=.37, p<.001), empathic ability (β=.30, p<.001), severe depression (β=.14, p=.008), gender (β=.13, p=.010), and grade (β=-.13, p=.037); while the factors affecting communication were, in descending order, self-leadership (β=.41, p<.001), empathic ability (β=.23, p<.001), and gender (β=.11, p=.035). Moreover, the explanatory power of promoting relationships scored the highest at 31 %, followed by others' temperament at 27 % and communication at 26 %. Conclusion : The results of this study reveal the factors that influence the interpersonal skills of nursing students. To increase the interpersonal skills of nursing students, it is necessary to develop and apply regular curricula and programs designed to strengthen their self-leadership and empathic ability and to reduce their depression through reflecting differences between genders and grades.
