The purpose of this study is to analyze the awareness and needs for community based Telerehabilitation(TR) service by carrying out a online survey targeting individual with disabilities. By using the survey, we attempt to utilize the results as the basis for the health promotion and effective rehabilitation service to the disabilities in the community. Survey was conducted on the 162 target users, who use center for independent living, are registered as disabled. There are 34 questions in total. The results of the study are as follows. First, 74.7% of respondents said 'they had never heard of TR service'. 68.3% of the respondents said that 'they want to use the service' and 78% are positive about the service. Second, 84% of them said 'they have an intend to participate the service', 87.1% of the respondents answered that they needed 'very necessary' and 'necessary' in the question of necessity. Third, as a results of searching the requirements for TR service, it was found that there are requirements such as service system and construction considering the characteristics of the disabled, service provision of rehabilitation experts, and various program composition. Based on the results of this study, we suggest the development of a differentiated TR system program to improve the quality of rehabilitation for individuals with disabilities by considering the reality of rehabilitation treatment of community disabled people and considering the knowledge and needs of TR system.

We investigated seasonal variations in the abundance of the adults and the resting eggs of copepods to understand the role of copepod resting eggs for maintaining their population inhabiting the coastal area of Dadaepo, Korea. Adults and resting eggs of copepods were collected bi-monthly with a conical net (45 cm mouth diameter, $330{\mu}m$ mesh size) and van Veen grab ($0.1m^2$ area), respectively, from October 2016 to September 2017. The species of resting eggs were identified using mtCOI gene. The mean abundance of copepods was highest in October ($3686{\pm}1190inds{\cdot}m^{-3}$) and lowest in January ($176{\pm}60inds{\cdot}m^{-3}$) with the dominance of Paracalanus parvus s.l.. Among copepod producing resting eggs, Acartia omorii and Centropages abdominalis were dominant. The mean abundance of resting eggs was the highest in July ($9148{\pm}6787eggs{\cdot}m^{-2}$) and the lowest in October ($530{\pm}348eggs{\cdot}m^{-2}$). Most of the collected resting eggs were identified as A. omorii's. The mean abundances of A. omorii adults and resting eggs were highest in July, and both abundances fluctuated in a similar pattern except in September. In September, A. omorii adults were observed in a state of low abundance, while their resting eggs occurred in a state of high abundance. These results suggest that A. omorii maintain their population by producing a large quantity of resting eggs, particularly diapause eggs, before the seawater temperature rises. These eggs would hatch and be newly recruited to their population when the environmental condition becomes favorable.

Objectives: The Korea National Health and Nutrition Examination Survey (KNHANES) is a national surveillance system that has been assessing the health and nutritional status of Koreans since 1998. Based on the National Health Promotion Act, the surveys have been conducted by the Korea Centers for Disease Control and Prevention (KCDC). Methods: An oral examination as part of The National Health and Nutrition Examination was proposed to calculate the sample design and survey participation. The surveying system was presented by classifying the measurement environment, screening, and survey items by year, and the merits and limitations of using the data were suggested by examining the status of survey quality management and the process of disclosing raw data. Results: This nationally representative cross-sectional survey samples approximately 10,000 individuals each year and collects information on oral examinations and oral health interviews. Data for the oral health component of KNHANES was obtained to assess the oral health status of Koreans and determine the prevalence of dental caries and periodontitis. The oral health data quality control of KNHANES was composed of three parts: "Education Program" and "Field Training Program" for quality control of oral health examiners (dentists) by the professional academy, and "Data management" by the KCDC. After completion of the three-step data check, the indicators of dental caries, periodontal disease, and oral health behavior were published in the National Health Statistics. Conclusions: To achieve the goals of oral health indicators, we will continue to monitor so that we can use it as basic data for oral policies and carry out various linkage analyses related to oral diseases.

This study aimed to identify the factors affecting the nursing performance and the convergence relationships of leisure satisfaction, job stress, and nursing performance among nurses. Participants included 150 nurses working at 2 hospitals in C city from August 3 to September 15, 2018. The data were analyzed using descriptive statistics, independent t-test, one-way ANOVA with Scheffe's test, Pearson correlation coefficients, and multiple regression by SPSS 23.0 program. Nursing performance were significantly differences in age (F=4.78, p=.003), marital status (F=2.74, p=.007), length of clinical career (F=3.34, p=.012), and health condition (F=5.23, p=.002). Nursing performance was a positively correlated with leisure satisfaction (r=.32, p<.001) and a negatively correlated with job stress (r=-19, p=.020), and job stress was a negatively correlated with leisure satisfaction (r=-.32, p=.005). The factors affecting the nursing performance of clinical nurses were age (${\beta}=.20$, p=.008) and leisure satisfaction (${\beta}=.28$, p<.001), and these variables explained about 19.6% of the variance in nursing performance. In order to improve nursing performance, it is necessary to provide working environment and institutional support for increasing leisure satisfaction and reducing job stress and age-differentiated approaches.

Atacamite and Verdigris were studied material scientific properties and durability that are used for traditional green pigment in traditional art painting work and Dancheong. As a result of ingrediant analysis, K-AA and K-VA identified Atacamite and Hoganite (or Verdigris) respectively. In order to find a factor of depressing the stability of pigment, we examined UV radiant exposure test, CO2/NO2 gas corrosion test and salt spray test. Salt spray test damaged both samples which were formed salt particle on the surface of the samples and it makes color disability. Furthermore, the results of gas corrosion test that both pigments change color enough to be perceived by the naked eyes showed that an air pollutant NO2 gas is also considered to be a major damage factor. In the case of K-VA, Hoganite that is main component of sample changes Tenorite with turn black after accelerated UV radiant exposure test. The consequences of the atmospheric environment effect test of the two pigments, K-VA showed relatetively weaker than K-AA.

Storage racks have suffered huge losses due to earthquakes, but related research and regulations are relatively insufficient non-structural elements compared to the structural elements. In this study, we tried to experimentally analyze the behavioral characteristics of storage racks due to external force according to the fixing conditions of the column-foundations connection of storage racks. In general, the column-foundations connection of storage racks is installed according to the user's convenience without installation standards and regulations. For this reason, this study conducted a behavior analysis test on four full-scale storage racks with the condition of column-foundations connection of four typical storage racks. The behavior characteristics analysis test was performed by two-direction of the shake table with El-Centro seismic wave. To confirm the behavior characteristics according to the magnitude of the seismic load, 50% ~ 150% of the seismic waves were increased by 50% for each test. In addition, a resonance search test was conducted to confirm the natural frequency of each storage racks foundations fixing condition. Among the data obtained through the test, the displacement of the top layer and the permanent displacement after the test were compared for each condition to analyze the behavior characteristics of the column-foundations fixed conditions of the storage racks. As a result, the change of natural frequency was small in storage racks due to the change of the conditions of the foundations, and the behavior characteristics were changed due to the difference of the restoring force due to the change of the storage racks foundations condition rather than the influence of the natural frequency of the input load.

Background: The importance of infection with COVID-19 is being emphasized in dentistry with high risks such as aerosols. The purpose of this study is to investigate the knowledge and practice of infection control, stress and coping, and turnover of dental hygienists. Methods: Questionnaire was conducted knowledge and practice of infection control, occupational stress and coping, turnover. Survey data was investigated about 149 dental hygienists from February to March 2021 Data were analyzed t-test, ANOVA, Pearson's correlation using statistical programs of PASW Statistics ver. 21.0. Results: Regarding occupational stress, relationship conflict was higher in the group with less than 2 years of experience (p<0.05). Job anxiety, organizational system, inadequate compensation, and workplace culture were highly surveyed in the 3 to 5 year of experience. The group with more than 6 years of experience had the highest perception of lack of job autonomy (p<0.05). The group with higher knowledge of infection control had lower mean inappropriate rewards and stress (p<0.05). The group with high infection control performance had a lower average in items such as job instability, organizational system, inadequate compensation, workplace culture, and stress. And problem-focused coping ability was found to be high (p<0.05). Infection control knowledge and performance were positively correlated (r=0.251, p<0.01), infection control practice and stress were negatively correlated (r=-0.264, p<0.01), and stress and emotional coping were positively correlated (r=0.367, p<0.01). Stress was positively correlated with turnover rate (r=0.549, p<0.01). Conclusion: Infection control training was required to reduce occupational stress. Occupational stress was highly correlated with turnover, a holistic and systemic organizational operation and improvement of the quality of medical care were required to reduce stress.

Crucian carp, Carassius carassius (Weight 28.1±3.7 g, Length 10.0±1.0 cm) were challenged with Aeromonas hydrophila at 0, 2.0×10⁴, 2.0×10⁵, 2.0×10⁶, 2.0×10⁷ CFU/ml for 2 weeks. The lethal concentration 50 (LC₅₀) at 2 weeks of C. carassius challenged with A. hydrophila was 19.776×10⁵ CFU/ml. In hematological parameters, the hemoglobin and RBC counts were significantly decreased by A. hydrophila challenge, whereas there was no significant change in hematocrit. The inorganic plasma components such as magnesium and calcium were significantly decreased. In organic plasma components, glucose and cholesterol were significantly increased by A. hydrophila challenge, whereas total protein was significantly decreased. In enzymatic plasma components, ALP (Alkaline phosphatase) were significantly increased by A. hydrophila challenge. The results of this study suggest that the A. hydrophila challenge to C. carassius induced the significant physiological changes in the hematological parameters and plasma components as deadly pathogenic bacteria.

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.
