The objective of this study was to analyze the effect of characteristics of maritime telemedicine (service quality, recognition or not of service, health counselling service experience or not) on seafarer's satisfaction, and also analyze the effect of seafarer's satisfaction on loyalty. This study's data was collected from the Research Report of Survey of telemedicine service subjects in 2017 conducted in the maritime telemedicine pilot project. However, only 103 seafarers who received maritime telemedicine (Tele-Monitering) services were analyzed statistically. The main results of this study were as follows. ⅰ) Better service quality led to higher levels of satisfaction, ii) High levels of seafarer's satisfaction led to high levels of loyalty, iii) Seafarers whose age is under 50 than 30 years old are less satisfied, ⅳ) In total boarding career, Seafarers with more than 5 years but less than 10 years were more satisfied than seafarers with less than 5 years, ⅴ) Seafarers with more than 10 years but less than 15 years were more satisfied than seafarers with less than 5 years, ⅵ) Seafarers with more than 15 years but less than 20 years were more satisfied than seafarers with less than 5 years, ⅶ) Also, Seafarers in excess of 20 years were more satisfied than seafarers with less than 5 years, In conclusion, ⅰ) Better service quality led to higher levels of satisfaction and loyalty. Accordingly, the improvement of service quality is not only an important factor in improving satisfaction and loyalty, but also plays an important role in forming a positive image of maritime telemedicine. ⅱ) Seafarers with younger age and lower overall total boarding career were more satisfied. It is believed that the seafarer who are willing to use telemedicine and who are willing to refer to others are young.

This retrospective study investigates the accuracy of triage procedures for pediatric patients in emergency departments (EDs) using the Korean Triage and Acuity Scale (KTAS). The study includes 250 randomly selected initial nursing records and clinical outcomes of pediatric patients who visited one regional ED or a local ED from October 2016 to September 2017. The collected data were analyzed by a qualified expert to determine the true triage score. The accuracy of triage was defined as the agreement between the triage score of the emergency nurses (ENs) and the true triage score as determined by the expert. Based on expert comments, the cause of the triage error was analyzed and the KTAS score was compared with the discharge, length of stay (LOS), and medical cost. The results showed that the degree of agreement in the triage score between the experts and the ENs was excellent (weighted kappa=0.77). Among the causes of triage discordance, the most frequent was the incorrect application of vital signs to the KTAS algorithm criteria (n=13). Patients with high severity KTAS levels 1 and 2 were discharged less often (${\chi}=43.25$, p<0.001). There were significant differences in the length of stay (F=12.39, p<0.001) and cost (F=11.78, p<0.001) between KTAS scores when adjusting for age. The results of this study indicate that KTAS is highly accurate in EDs. Hence, the newly developed triage tool is becoming well established in Korea.

The purposes of this study was to confirm the current issues of workforce policy of dental auxiliary personnel in Korea. The literature review and data collection were conducted in terms of the auxiliary personnel supply, regional distribution, legal works, working environment. Despite the rapid increase in the number of dental hygienists, the number of active dental hygienists is less than half of the total, and the dental clinics still experience the shortage. Considering the dental hygienist's work, the available dental auxiliary personnel for the dental assistance is limited. The proportion of dental hygienists is concentrated in large cities, and the ratio of dental clinics composed of only dental hygienists is high. Thus, it is essential to look for a plan to solve the disparity. The criterion for judging the legality of the works is ambiguous because a large portion of dental hygienist's work is not specified in the Medical Technicians Act. The job life is also shortened, and occupational profession and satisfaction are lowered. Thus, job burnout is accelerating. The difference between the legal works and the practiced works of dental hygienist and the conflict between the personnel might be due to the lack of utilization plans for the dental personnel at the government level. Therefore, the government should establish the roles of dental hygienist in accordance with the demands of the dental health service, institutionalize the necessary policies accordingly, and make efforts to establish plans to improve the relevant laws and utilize the manpower appropriately.

The number of antibiotic-resistant bacteria is increasing rapidly while the discovery rate of new antibiotics is in decline. A systematic study is therefore necessary to investigate which bacteria are resistant to medically important antibiotics and how high that resistance is. To that end, this study aimed to analyze which bacteria demonstrated resistance to ampicillin, one of the currently most-widely used medical antibiotics. Water samples were collected from the Changwon-Cheon that runs through Changwon City and from the pond in front of the dormitory building at Changwon University. Hundreds of ampicillin-resistant colonies were obtained and 22 morphologically distinct examples were chosen for further study. These bacteria were identified by amplifying their 16S rRNA genes and comparing those sequences with data in GenBank. The bacteria was identified as belonging to 10 families, 12 genera, and 17 species, and all were able to grow in the presence of $50{\mu}g/ml$ ampicillin while seven showed growth at ampicillin concentrations as high as 1.5 mg/ml.

Objective: The purpose of this study was to investigate whether there is a difference in the brain connectivity in mental practice and physical performance of training bilateral upper extremity function. Method: The subject performed activities involving mental tasks and physical exercise for bilateral upper extremity functioning during each phase of EEG measurements. The subject performed a symmetrical task(lifting a box and placing it back) that involved moving both arms at the same time and an asymmetrical task(opening and closing a bottle cap) in order to perform functional tasks. EEG electrodes were attached to Fp1, Fp2, F3, F4, T3, T4, P3, and P4. Data analysis was performed using Cross-Line Mapping for correlational analyses between EEG electrode pairs. Conclusion: This study found that the brain connectivity patterns of symmetrical and asymmetric upper extremity tasks have similar patterns for the motor and sensory area, and that the correlation of the physical practice is generally higher than that of the mental practice.

Objective : The purpose of this study was to examine the differences between motor functions and executive functions according to the timing of children with attention deficit hyperactivity disorder (ADHD). Methods : The subjects were 32 children with ADHD aged between 6 and 12 living Busan. To assess the timing, Long Form Assessment (LFA) of Interactive Metronome (IM) was used. Bruininks-Oseretsky of Motor Proficiency, Second Edition (BOT-2) were also used to assess motor functions. STROOP Color and Word Test and Children's Color Trails Test were used to evaluate executive functions. Mann-Whitney U tests were used to determine the differences between the executive functions and the motor functions according to the timing. Results : Comparing the inter-group motor functions according to the timing, there was a statistically significant difference in the Fine manual control and Fine motor precision in BOT-2 (p<.05). Comparing the inter-group executive functions according to the timing, there was not statistically significant difference (p>.05). Conclusion : Among the deficits in ADHD children, we could see the differences between motor function and executive function according to timing function. This study would be meaningful in that the results could be a basic data for study on the timing of children of ADHD in the future.

The purpose of this study is to compare motivations for self-archiving across disciplines on an academic social networking site. We carried out an online survey with ResearchGate(RG) users, testing 18 motivational factors that we developed from a previous study (enjoyment, personal/professional gain, reputation, learning, self-efficacy, altruism, reciprocity, trust, community interest, social engagement, publicity, accessibility, self-archiving culture, influence of external actors, credibility, system stability, copyright concerns, additional time, and effort). We adapted Biglan's classification system of academic disciplines and compared motivations across different categories of discipline. First, we compared motivations across the four combined categories by the two dimensions - hard-pure, hard-applied, soft-pure, and soft-applied. We also performed a motivation comparison across each dimension between soft and hard disciplines and between pure and applied disciplines. We examined investigated statistical differences in motivations by demographic characteristics and RG usage of participants across categories as well. Findings showed that there were differences of motivations, such as enjoyment, accessibility, influence of external actors and additional time and effort, and personal/professional gains, for self-archiving across disciplines. For example, RG users in the hard-applied were more highly motivated by enjoyment than others; RG users in the soft-pure were more highly motivated by personal/professional gains than others. It is expected that findings could be used to develop strategies encouraging researchers in various disciplines contributing to share their data and publications in ASNSs.

The purpose of this study was to identify the factors that influence the organizational commitment of clinical dental hygienists to contribute to manpower management. The subject of the study was 195, and the following results were obtained as a result of collecting and analyzing data using a self-filling questionnaire from March 10 to April 20, 2020. The degree of organizational commitment, job satisfaction, and internal marketing according to general characteristics were analyzed by t-test and one-way ANOVA, and post-test was set to'Scheffe'. The correlation between organizational commitment, job satisfaction, and internal marketing showed a significant positive correlation with job satisfaction (r=0.689) and internal marketing (r=0.678). The factors influencing organizational commitment were multiple regression analysis, and the influencing factors for organizational commitment were internal marketing and job satisfaction. The most influential factor was job satisfaction, and the explanatory power was 56.1%.As a result, the internal marketing of clinical dental hygienists was found to be related to job satisfaction and organizational commitment, and the factor that most affected was job satisfaction. Therefore, institutional and administrative support from dental medical institutions is needed to improve job satisfaction, which has an impact on organizational commitment of clinical dental hygienists.

With a long-lasting pandemic of COVID-19, we have faced unprecedented socioeconomic threats. The regulation of human exchange has exposed us not only to the threat of health and medical care problems, but also to the burden of the contraction of economic activity. The outbreak of COVID-19 did give us an opportunity to reexamine the social safety net which has been prepared for such crisis situations. The current study, in this vein, aims to investigate the impact of evaluations of social safety nets on the trust in government and on individual willingness to accept tax increases. To this end, this study has explored the data from a survey conducted on 1,000 adult men and women across the country (South Korea) in May, 2020, when COVID-19 has entered a pandemic phase. The analysis result then has shown that the evaluation of social safety net after the outbreak of COVID-19 had a positive impact on the trust in the government, which in turn led to the increase of the willingness to accept tax increases. Moreover, the positive impact of trust in government on the willingness to accept tax increases has been more amplified when the income level was increased. These results could contribute to laying the theoretical foundation for restructuring the policies and systems for the post COVID-19 era.
