This study analyzed the characteristics of land use changes around urban railway stations in peri-urban mixed-use cities. The research focused on four station areas along the Gyeonggang Line in Gwangju City, Gyeonggi Province, categorized into three phases based on their opening dates to analyze land use changes. The analysis method utilized building permit registry data from 2012 to 2020 within a 1 km radius of each station, at 250-meter intervals, examining temporal, spatial, and functional distributions. Statistical analysis employed SPSS for weighted cross-tabulation to explore differences in building permits and concentration levels among various building types. The findings revealed: firstly, peri-urban mixed-use city station areas exhibited the highest number of building permits at the time of opening; secondly, significant land use changes were observed within the 500-meter radius from the station; thirdly, residential buildings dominated, reflecting a trend towards housing supply-oriented land use changes; fourthly, cross-tabulation indicated significant differences in building permits across time, distance, and type (p < 0.01). Lastly, the concentration analysis revealed that residential buildings were distributed most evenly, while buildings for educational, social, and agricultural and fisheries purposes were distributed unevenly.

Objectives : Cervical myofascial pain syndrome (C-MPS), a key aspect of Visual Display Terminals (VDT) Syndrome, leads to acute and chronic pain due to muscle shortening, potentially causing headaches and movement disorders. This study examines the effectiveness of Pharmacoacupuncture at the intersection of the Splenius Capitis (SC), Levator Scapulae (LS), and Serratus Posterior Superior(SPS) muscles under ultrasound guidance, known as the "SLS triangle" in treating C-MPS. Methods : Three patients (aged 30 to 37) with acute C-MPS presented at two Korean medicine clinics with severe neck pain and restricted cervical rotation. The evaluation of symptoms before treatment, immediately after treatment, and one day after treatment was conducted using the cervical rotation Range of motion (ROM) and the Numeric Rating Scale (NRS) for cervical pain. Treatments included Acupuncture, Cupping therapy, Chuna manipulation, Physical Therapy, and Pharmacopuncture (Jaha-geo extract, 2cc at the SLS triangle). Results : All three patients showed significant improvement post-treatment. Immediately after treatment, Patient 1's NRS improved from 7 to 2, Patient 2's NRS improved from 4 to 1, and Patient 3's NRS improved from 6 to 2. Directly after the procedure, there were no significant adverse reactions except for one patient experiencing temporary dizziness. When the patients were followed up by phone 24 hours later, no adverse reactions were reported. Conclusions : This study demonstrates that ultrasound-guided pharmacopuncture can significantly reduce pain and improve cervical rotation in patients with cervical myofascial pain syndrome. The findings suggest this non-invasive treatment is both safe and effective, warranting further research through larger-scale clinical trials to validate its efficacy and establish standardized protocols.

The purpose of this study was to analyze the mediating effect of beauty workers' presenteeism on job burnout in the relationship between job performance and job turnover. The participants in this study were 272 beauty workers in Seoul and Gyeonggi Province, and data were collected through a structured questionnaire. The collected data were analyzed through descriptive statistics, confirmatory factor analysis, correlation, structural equation model, and mediation effect analysis using bootstrapping method using SPSS and AMOS 26.0 statistical programs. The conclusions drawn through a series of research procedures are as follows. First, beauty workers' presenteeism was found to have a statistically significant positive (+) effect on job burnout. Second, beauty workers' presenteeism showed a statistically significant positive (+) effect on turnover intention, but no significant relationship was found with job performance. Third, job burnout among beauty workers was found to have a statistically significant effect on job performance and turnover intention. Fourth, as a result of analyzing the mediating effect of beauty workers' presenteeism on job burnout in the relationship between job performance and turnover intention, the effect of presenteeism on job performance through job burnout showed a complete mediating effect, and it was different from turnover intention. It showed a partial mediation effect.

The purpose of this study was to explore the predictors of self-compassion correlated to mental health, and to suggest integrated self-compassion training and mental health practice plans for social welfare college students. Although self-compassion has been shown to be an important predictor in maintaining personal mental health, research on practical knowledge to improve level of self-compassion is limited. Therefore, there is a need to explore the relationship between predictors related to self-compassion for suggesting alternative interventions. This study used resilience, mental health well-being, and engagement scales whose relationships have been explored in self-compassion studies. Data was collected for 2021-2022 from third-year or higher social welfare college students in the metropolitan area. A total of 202 cases were analyzed, and correlation and regression analysis were applied using SPSS. Self-compassion was positively correlated with resilience, mental health well-being, and engagement. Resilience and mental health well-being were identified as important predictors of self-compassion. Unlike self-compassion, resilience and mental health well-being are familiar with social welfare students and educators, and existing resilience training and well-being education would be integrated to improve self-compassion capability.

The purpose of this study was to explore various factors that affect the organizational commitment of health teachers' behavioral characteristics and explain the causal relationship between each factor. As an exploratory study, the subjects were about 500 people working as health teachers. A survey was conducted, and 190 responses were collected. Descriptive statistics were analyzed using SPSS, and the measurement model and hypotheses were tested using structural equation modeling. As a result of the analysis, the behavioral characteristics of health teachers were found to have a positive effect on their self-efficacy, and the behavioral characteristics and self-efficacy were found to have a positive effect on emotional commitment. In addition, health teachers' self-efficacy has a positive effect on emotional commitment, which means that rather than their behavioral characteristics having a direct effect on emotional commitment, their behavioral characteristics indirectly affect emotional commitment through a mediator called self-efficacy. It shows that it has an impact. In particular, it was confirmed that the school nurse's level of awareness of the importance of the task affected self-efficacy and emotional commitment. The implication of this study is that it explained the phenomenon of transfer of their behavioral characteristics to organizational commitment by empirically revealing that the competency, or behavioral characteristics, of health teachers are a factor affecting organizational commitment through self-efficacy. The goal is to empirically demonstrate that awareness of task importance, a job characteristic, affects self-efficacy and organizational commitment. The results of the study are expected to be able to suggest directions for capacity building and operation of health teachers.

This study intends to identify the main triggers of consumer participation behavior by multi-dimensionally reviewing factors affecting active participation behavior in order for consumers to receive better service at service encounter. We also want to review the impact of service contact employees' human services on consumers' experience of positive and negative emotions while performing participation behavior. This study targeted beauty salon services. Beauty salon services are one of the most important industries for human services because of the relatively long time interaction and the high degree of consumer participation that has a great influence on service outcomes. For an empirical analysis survey was conducted on 446 general consumers. SPSS and AMOS analysis was performed. The results of this study are as follows. First, relational benefits were not significant for consumer participation behavior, and functional benefits and hedonic benefits were significant. Consumer participation behavior was found to have a significant effect on positive emotions, but not on negative emotions. It has been shown that the service provider's human service has a significant effect on both positive and negative emotions. Finally, both positive and negative emotions were found to have a significant effect on service quality. Since beauty services are an industry with high social visibility, it has been shown that relational benefits does not significantly affect consumer participation. Negative emotions perceived by consumers did not significantly affect service quality. It may mean that some negative emotions are insignificant. Further studies will need to classify the negative emotion dimension more closely. It is necessary to review the feelings arising from service employees. Finally, it is necessary to review the various types of services of contact employees.

Purpose: Manufacturing with AM (Additive manufacturing) technique has many advantages; but, due to insufficient study in the area, it is not being widely used in the general clinic. In this study, differences of flexural strength among various materials of 3 unit fixed dental prosthesis were analyzed. Materials and Methods: A metal jig for specimens that had a 3-unit-fixed dental prosthesis figure were fabricated. The jigs were made appropriately to the specifications of the specimens. Three different kinds of materials of specimens which were NC (mathacrylic esther based), DP-1 (Bisphenol A epoxy acrylate type oligomer based), and DT-1 (urethane acrylate based) were printed with DLP machine. Five specimens for each kind of material were printed with an angle of $30^{\circ}$ from the horizontal surface. The specimens were placed on the jig and the flexural strength was measured and recorded using Universal testing machine. The recorded data was analyzed in SPSS using One-way ANOVA and Tukey HSD to determine the significance of the differences of flexural strength among the groups. Results: The flexural strengths of each group were the followings: NC, $1119{\pm}305$ N; DP-1, $619{\pm}150$ N; DT-1, $413{\pm}65N$. Using One-way ANOVA and Tukey Honestly Significant Difference test, significant difference was found between NC and the other groups (P < 0.05), but there was no significant difference between DP-1 and DT-1 (P > 0.05). Conclusion: Higher flexural strength was shown in 3-unit-fixed dental prosthesis that were 3D printed using a DLP machine with NC material.

The community structure, vertical distribution and harpacticoids composition of the meiofauna community were observed from five stations in Marian Cove, King George Island and one station on the northeastern side of Nelson Island. Sample was taken by a free-fall corer in December 2002. Generally, 11 taxa of meiofauna were found, and meiofauna abundance ranged from 322 to 1575 indiv. $10cm^{-2}$ (mean 781 indiv. $10cm^{-2}$). Nematodes were the most dominant group, making up $89\%$ of total meiofauna, followed by harpacticoids $(6.8\%)$. Benthic harpacticoids appeared 19 species of nine families at all the stations, and most various taxa appeared at station B (13 species of seven families). For vertical distribution, more than $70\%$ of meiofauna was concentrated in the upper $0\~2cm$ sediment layers, and the density abruptly decreased with depth in all the stations. Total biomass of meiofauna varied between 41 and $360{\mu}gC\;10cm^{-2}$, and overall mean biomass was $205{\mu}gC\;10cm^{-2}$. Also nematodes had the highest percentage of total maiofauna biomass $(62.4\%)$. The analysis results of Canonical Correspondence Analysis between meiofauna community and sediment grain size showed that polychaets, oligochaets and cumaceans were influenced by silt&cray, and sand, granule and pebble had a influence on harpacticoids, kinorhynchs and ostracods respectively. But nematodes were not affected by sediment grain size.

This study aimed to investigate the difference of X-ray exposure by comparing and analyzing entrance surface dose and absorbed dose according to the frame change in coronary angiography using an X-ray machine. Moreover, appropriate frame selection measures for examination, including the effect of frame change on the image quality, were sought by measuring and analyzing the SNR and CNR of the image through image J. The study was conducted on 30 patients (19 males and 11 females) who underwent CAG at this hospital from June 2017 to October 2017. In regard to the patients, their age range was 49-82 years (mean of $65{\pm}9$ years), body weight was 45-91 kg (mean of $67{\pm}8.9kg$), height was 150-179cm (mean of $165.1{\pm}8.9kg$), and BMI was 19.5-30.5(mean of $24.5{\pm}2.9$). For the entrance surface dose and absorbed dose, air kerma value and DAP were obtained and analyzed retrospectively. The SNR and CNR were measured and analyzed through imageJ, and the result values were derived by applying the values to the formula. As for the statistical analyses, the correlations between the entrance surface dose and absorbed dose, and between the SNR and CNR were analyzed by using the SPSS statistical program. The relationship between the entrance surface dose and absorbed dose was not statistically significant for both 10 f/s and 15 f/s (p>0.05). In terms of the relationship between the SNR and CNR, the SNR ($3.374{\pm}2.1297$) and CNR ($0.234{\pm}0.2249$) in 10 f/s were $1.43{\pm}0.4861$ and $0.132{\pm}0.0555$ lower, respectively, than the SNR ($4.929{\pm}2.8532$) and CNR ($0.391{\pm}0.3025$) in 15 f/s, which were not statistically significant (p>0.05). In the correlation analysis, statistically significant results were obtained among the BMI, air kerma, and DAP; between air kerma and DAP; and between SNR and CNR (p<0.001, p<0.001). In conclusion, there was no significant difference between the entrance surface dose and absorbed dose even when the images were taken by changing the frame from 10 f/s to 15 f/s at the time of the coronary angiography. SNR and CNR increased at 15 f/s than at 10 f/s, but they were not statistically significant. Therefore, this study suggests that the concern of the patient and practitioner regarding image quality degradation, as well as the problem of X-ray exposure caused by imaging at 10 f/s and 15 f/s, may be reduced.

Purpose : We aimed to compare the effectiveness of 2 developmental tests-Korean Infant and Child Development Test (KICDT) and Korean Bayley Scale of Infant Development-II (K-BSID-II)-in the assessment of children with developmental delay. Methods : Twenty-eight children with suspected developmental delay, who visited the Department of Pediatrics in Asan Medical Center from February 2007 to June 2008 were enrolled. They were examined using both KICDT and K-BSID-II. The results of the tests were compared on the basis of 2 parameters: age group of the children and detection of organic brain lesion on magnetic resonance imaging (MRI). The correlation between the results of the 2 tests was analyzed using SPSS. Further, intraclass correlation coefficient was calculated using SAS to examine consistency between the results of the 2 tests. Results : The mental developmental index of K-BSID-II showed significant correlation with every KICDT score (P<0.01). The psychomotor developmental index of K-BSID-II was also significantly correlated with every KICDT score except the fine motor score (P<0.01). The mental developmental index of K-BSID-II showed significant correlation [Editor20] with the KICDT gross motor, fine motor, and language scores (P<0.05). Further, there was significant correlation between the psychomotor developmental index of K-BSID-II and the KICDT gross motor score (P<0.05). Conclusion : There was significant [Editor21]correlation between the results of KICDT and K-BSID-II for infants and children with developmental delay. Although our results suggest that KICDT is useful in assessing developmental delay, further research would be needed to standardize this test.
