This study has significance in terms of its intent to contribute to the increase in hospital revisits by proposing measures to enhance name awareness through an examination of the relationship between the name awareness of public medical institutions and patients' revisit, and its corresponding influences. The study findings were drawn by employing analysis methods such as frequency analysis, reliability and exploratory factor analysis, t-tests, ANOVA, correlation analysis, and hierarchical multiple regression analysis. The results of the correlation analysis showed statistically significant correlations between all independent variables and the patients' revisit or not. The perception of service quality and the environmental factor of medical treatment increased the explanatory power of independent variables, thereby exhibiting a high correlation with the revisit to medical institutions. The usual image, medical service, and medical treatment environment were revealed to have a positive influence on the patient's intent to revisit. This study could confirm a correlation between the name awareness of medical public institutions and the patients' revisit or not. Consequently, to improve the quality and infrastructure of their medical services, public medical institutions are required to perform studies on measures to increase the revisits of patients by identifying their image, medical services, and treatment environment on a consistent basis.

The aim of this study was to evaluate the quality characteristics, antioxidant activities, and sensory properties of macaron with Opuntia ficus-indica var. saboten powder (OP). Physicochemical and sensory properties of macaron with different amounts (0%, 2%, 4%, and 6%) of OP were examined. The quality of macarons was evaluated based on spread factor, baking loss rate, color, texture, antioxidant activities, and sensory evaluation. As amount of OP addition increased, spread factor and a value increased, whereas baking loss rate, and L and b values decreased (p<0.05). For texture properties, hardness, springiness, and brittleness were lower as OP content increased while cohesiveness and gumminess were not significantly different (p<0.05). For total polyphenolic contents, DPPH and reducing power significantly increased upon addition of OP at high concentrations (p<0.05). In the sensory evaluation of macarons, scores for color, flavor, taste, texture, and overall acceptance were highest with 4% OP, whereas macaron containing 6% OP showed the lowest scores for taste and texture (p<0.05). These data suggest that addition of 4% OP is the optimal concentration for making macaron.
For enhancing productivity of glulam, high frequency (HF) curing technique was researched in this study. Heat energy is generated by electromagnetic energy dissipation when HF wave is applied to a dielectric material. Because both lamina and adhesives have dielectric property, internal heat generation would be occurred when HF wave is applied to glulam. Most room temperature setting adhesives such as phenol-resorcinol-formaldehyde (PRF) resin, which is popularly used for manufacturing glulam, can be cured more quickly as temperature of adhesives increases. In this study, dielectric properties of larch wood and PRF adhesives were experimentally evaluated, and the mechanism of HF heating, which induced the fast curing of glue layer in glulam, was theoretically analyzed. Result of our experiments showed relative loss factor of PRF resin, which leads temperature increase, was higher than that of larch wood. Also, it showed density and specific heat of PRF, which are resistance factors of temperature increase, were higher than those of wood. It was expected that the heat generation in PRF resin by HF heating would occur greater than in larch wood, because the ratio of relative loss factor to density and specific heat of PRF resin was greater than that of larch wood. Through theoretical approach with the experimental results, the relative strengths of ISM band HF electric fields to achieve a target heating rate were estimated.
To continue the growth of use of 5-star hotels by Koreans, who have recently shown the consumption trends pursuing the empirical value of a consumption process, and have turned into core customers of 5-star hotels in Seoul, it is necessary to study factors of experience value pursued by Koreans. As a result, fantasy is identified as a major leading factor in usage satisfaction among experiencial values. So it is important to reflect special concepts and atmospheres for emotional values, such as other world experience, new experience, and high-quality experience. And consumer return on investment was identified as a leading factor in positively affecting usage satisfaction. So it is important to develope a proper products that can enough benefits with reasonable prices. In the relationship between usage satisfaction and continuous usage intention, gender characteristics and occupational characteristics were found to play a moderating role. Male customers, and those with professional and self-employed occupations, were found to have higher continuous usage intention than females and other occupational customers. This is a result of the fact that customers with an economical power are likely to be continuous repeat customers of 5-star hotels, so the necessity of strengthening marketing activities such as research on the development of more differentiated and specialized products, service creation and atmosphere production for excellent consumers group.
This study aimed to identify workplace learning, job satisfaction and geriatric nursing practice, find the correlations between each variable, and investigate affecting factors on geriatric nursing practice. Subjects were 146 nurses in 9 long-term care hospitals including G City, and data were collected from May 1, 2016 through Jun. 30, 2016. Data analysis included independent t-test, one-way ANOVA, Pearson's correlation coefficient and multiple regression using the SPSS/WIN 20.0 program. The results showed that the correlations between each variable showed that incidental learning, a subregion of workplace learning (r=.20, p=.014), and job satisfaction (r=.29, p<.001) had a positive correlation with geriatric nursing practice, respectively. The affecting factors on geriatric nursing practice were job satisfaction, daytime working and nursing experience, and the explanatory power of the model was 20%(F=4.91, p<.001). Based on the results, job satisfaction should be increased to improve the quality of nursing in long-term care hospitals and various methods might be discussed to improve the job satisfaction. Daytime working was suggested one factor on geriatric nursing practice because nursing was provided mainly during daytime, and nursing experience was also one factor on geriatric nursing practice, so highly experienced geriatric nurses could provide high quality elderly patient care.
The aim of this study was to evaluate the quality characteristics, antioxidant activities, and sensory properties of macaron with cabbage powder (CP). Physicochemical and sensory properties of macaron with different amounts (0%, 1%, 3%, 5%, and 7%) of CP were examined. The quality of macarons was evaluated based on spread factor, baking loss rate, color, texture, antioxidant activities, and sensory evaluation. As amount of CP addition increased, spread factor, baking loss rate, and L and a values decreased, whereas b value increased (p<0.05). For texture properties, hardness, cohesiveness, and springiness were increased by addition of CP (p<0.05). The gumminess and brittleness did not show significant changes up to 3% CP addition although significant changes in 5-7% CP addition (p<0.05) were evident. The total polyphenolic contents, DPPH radical scavenging activities, and reducing power were significantly increased by addition of CP at high concentrations (p<0.05). In the consumer acceptance of macarons, 3% CP showed the highest in color, flavor, texture, and overall acceptance and 5% CP showed the highest in taste. Meanwhile, macaron containing 7% CP showed the lowest scores in texture and overall acceptance (p<0.05). These data suggested that adding 3% of CP was the optimal concentration for making macaron.

This study examines the relative usefulness of the TPB and Extended TPB with the addition of the "Battery" variable to participants in marine sports experiences. The characteristics of behavioral theories (attitude, subjective norms, perceived behavioral control, and revisit intention) were compared. A total of 420 questionnaires were distributed and surveyed using the convenience sampling method to the general public who participated in the marine sports experience in S city in 2019. Finally, 385 copies of valid samples were extracted, except for the questionnaire. The following analyzes were performed using SPSS 21.0 and AMOS 21.0. Frequency analysis, confirmatory factor analysis, concept reliability, AVE value, Cronbach's α correlation analysis, hierarchical regression analysis, and independent sample t-test were performed. First, in the TPB, three predictors were found to have a positive effect on revisit intention. Attitudes, subjective norms, and prior knowledge, except for behavioral control, were found to have a positive effect. Second, the explanatory power to explain the return intention was 51.8% (3.3% more than plan behavior theory, p = .000). It can be seen that when prior knowledge is added as a new variable, it is an important factor in explaining intention to return. Third, prior knowledge variables were classified into high and low groups to compare the characteristics of the extended planning behavior theory. The results of the analysis showed that the group with higher prior knowledge had a higher mean value for the constituent variables of the extended planning behavior theory.
The recycling of coal bottom ash generated from coal power plants in Korea has been limited due to heterogenous characteristics of the materials. The most common management option for the ash is disposal in landfills (i.e. ash pond) near ocean. The presence of large coarse and fine materials in the ash has prompted the desire to beneficially use it in an application such as fill materials. Prior to reuse application as fill materials, the potential risks to the environment must be assessed with regard to the impacts. In this study, a total of nine test cells with bottom ash samples collected from pretreated bottom ash piles and coal ash pond in a coal-fired power plant were constructed and operated under the field conditions to evaluate the leachability over a period of 210 days. Leachate samples from the test cells were analyzed for a number of chemical parameters (e.g., pH, salinity, electrical conductance, anions, and metals). The concentrations of chemicals detected in the leachate were compared to appropriate standards (drinking water standard) with dilution attenuation factor, if possible, to assess potential leaching risks to the surrounding area. Based on the leachate analysis, most of the samples showed slightly high pH values for the coal ash contained test cells, and contained several ions such as sodium, potassium, calcium, magnesium, chloride, sulfate, and nitrate in relatively large quantities. Three elements (aluminum, boron, and barium) were commonly detected above their respective detection limits in a number of leachate samples, especially in the early leaching period of time. The results of the test cell study indicate that the pollutants in the leachate from the coal ash test cells were not of a major concern in terms of leaching risk to surface water and groundwater under field conditions as fill materials. However, care must be taken in extending these results to actual applications because the results presented in this study are based on the limited field test settings and time frame. Structural characteristics and analysis for coal bottom ash may be warranted to apply the materials to actual field conditions.
This study is to decrease compound noise in x-ray films. This study compared Signal to noise ratio(SNR), Peak signal to noise ratio(PSNR), Mean square error(MSE) to surface of the earth. In addition, we evaluated noise elimination effect according to the kernel size of Median filter. This experiments show that some filters are useful by finding image that is near in circle image comparing circle picture with each processed picture. In noise power value, when cutoff frequency was compared with other filters of cutoff frequency. Cutoff frequency of $2/3\pi{\sim}3/4\pi$ is good and it shows good SNR and PSNR. Therefore, it can display high filter effect. As Median Filter's Kernel size grows SNR value gets bigger, which shows better filter effect. Most pictures are distorted after filter application in medical treatment image. It is important to keep spatial resolution in most medical images. Visual estimation as well as quantitative indicators should be necessary for a better image.
Epilepsy, characterized by enduring the predisposition to generate epileptic seizures, was conceptually defined in 2005 as a disorder of the brain. According to the international league against epilepsy in 2014 that there is a high risk of recurrence within 10 years. The existence of interictal epileptiform discharges (IEDs) at the Electroencephalography (EEG) is an important risk factor for a possible recurrence of seizures, disproving that the seizures may increase. The purpose of this study was to analyze the correlation between recurrent seizures and epilepsy EEG findings in patients with IEDs, which was carried out to serve as the basis for the EEG to predict the prognosis of patients with epilepsy. This study included 432 adults older than 20 years of age who care for patients with epilepsy at Seoul National University Hospital, between June 2007 and December 2010. The results showed no difference between men and women in the EEG epilepsy disease, but there was a difference between various age groups. Correlation analysis showed a negative correlation between recurrence of seizures and age; it showed a positive correlation between recurrence and IEDs. In addition, age was associated with a predictive power of 10.9% and IEDs showed a predictive power of 15% on recurrent seizures. Therefore, EEG is considered as a very important test in epilepsy diagnosis. Therefore, further studies are necessary on the relationship between seizure recurrence and EEG.
