This study investigated the quality characteristics of muffins containing Actinidia polygama powder, which is well known for its various functions and biological activity. With increasing Actinidia polygama powder, the volume, height and specific volume increased significantly. The height of the muffins prepared with Actinidia polygama powder was higher than that of the control group. The pH of the muffin decreased significantly with increased levels of Actinidia polygama powder. The moisture of samples raged from 26.83% to 30.86%. The L- and b-value decreased, while a-value increased, with increasing amounts of added Actinidia polygama powder. Textural profile analysis showed that the hardness, springiness and chewiness were decreased with increasing Actinidia polygama powder contents. As the Actinidia polygama powder content increased, 1,1-diphenyl-2picriylhydrazyl(DPPH) radical scavenging also significantly increased. The sensory evaluation results indicated that the group of 3% Actinidia polygama powder recorded the highest overall preference score at 6.20. The quality characteristics of the 3% added samples exhibited significantly similar or higher values as compared to those of the conrols, raising the possibility of development in health-functional muffins.

This study was undertaken to develop a subacute murine model for predicting occurrence of systemic anaphylaxis and to evaluate efficacy of various immunological parameters as the monitoring indices for the occurrence of anaphyalxis. The murine anaphyalxis model was developed through intraperitoneally sensitizing 100 $\mu\textrm{g}$ ovalbumin (OVA) in the presence of 1 mg alum and 300 ng cholera toxin twice a week interval followed by challenging 500 $\mu\textrm{g}$. OVA intravenously. Typical anaphylaxis symptoms were demonstrated at the both BALB/c mice, a strain prone to type-2 response, and C57BL/6 mice. a strain prone to type-1 response. Level of plasma histamine was approximately 50-fold or 30-fold higher in the mice sensitized with OVA than the mice sensitized with alum plus cholera toxin or the saline-treated mice after OVA challenge, respectively. Sensitization and challenge with OVA significantly enhanced plasma leukotriene $B_4$ level but not IgE levels in comparison with the control mice, which indicated the role of leukotriene $B_4$ for progression of anaphyalxis. Furthermore, among mice suffered from anaphylaxis, levels of OVA-specific IgGl were significantly higher in the BALB/c mice than in the C57BL/6 mice, which implied the genetic susceptibility for the induction of systemic anaphylaxis. Conclusively, simultaneous evaluation of histamine, leukotriene $B_4$, and allergen-specific IgG isotype may serve as more efficient monitoring tool for vaccine-related anaphyalxis.

Purpose: This cross-sectional survey research was undertaken to identify the factors influencing time from onset to hospital arrival of stroke patients and to provide basic information for the development of intervention programs for stroke patients. Methods: The data were collected using a convenient sampling method from three hospitals in Inchon. The subjects were 78 patients who were diagnosed as stroke by doctor and they voluntarily participated in the study. Results: On the average, subjects arrived at the hospitals by 16.72 hours after the onset of stroke events with the range from 0.17 hours to 72 hours. Thirty-four(43.6%) subjects arrived within 3 hours which can maximize treatment effects. There was significant difference in hospital presentation time according to the level of knowledge(${\chi}^2=18.629$, p=.0003). A negative correlation was found between the hospital presentation time and self-efficacy (r= -.320, p=.004). Stepwise multiple regression analysis revealed that the most powerful predictor was self-efficacy. Self-efficacy, the level of knowledge and physical symptoms were significant factors and accounted for 21.7% of the variance of hospital presentation time in stroke patients. Conclusion: According to the results, self-efficacy is a useful concept for reducing the hospital presentation time from onset of attack in stroke patients. Therefore, nurses should consider educational programs which include not only a knowledge of stroke and recurrence prevention but also the concept of self-efficacy.

The development of standards and guidelines of rehabilitation nursing has been the major concerns for providing better nursing to the rehabilitation clients. As the patients with stroke and spinal cord injuries are the most prevalent physical disabilities in Korea, this study focussed on the nursing diagnoses of these two groups of patients. In order to identify the nursing diagnoses frequently used In their practice for the patients with stroke and spinal cord injuries, a survey was done with the questionnaire form developed by the research team. The surveyee were the staff nurses working at rehabilitation wards more than 2 years from 8 general hospitals in Korea, They identified and set the priorities of 13 nursing diagnoses from 79 stroke patients and 10 nursing diagnoses from 35 patients with spinal cord injuries during the periods from March 1 to June 2, 1999. The identified nursing diagnoses for the stroke patients are impaired physical immobility, sensory-perceptual alteration, activity intolerance, self-care deficit, altered defecation, altered urination, risk for injury, unilateral neglect, impaired skin integrity, altered thought processes, pain, altered health maintenance, dysreflexia. The identified nursing diagnoses for spinal cord injuries are altered urination, altered defecation, impaired skin integrity, pain, risk for injury, reflex incontinence, impaired physical immobility, self-care deficit, activity intolerance, knowledge deficit.

We have developed and evaluated a smart clothing system for the measurement of body composition in real time. Two kinds of experimental clothes were developed in this study to investigate the effects of textile electrodes on the measurements. As long as the wearer maintained same posture, the magnitudes of impedance was measured identically even though he got into the clothing again. Moreover we found the clothing could measure the impedance of each body segment.

We studied new product presentation strategies for cheongyang Lycium chinense, and the attributes of consumers purchasing cheongyang; this is a popular herbal medicine. Attributes are characteristics or properties of a product, and generally refer to features regarded as evaluative criteria during decision-making. The key phrases found on data analysis were "free from disease" and "health". Makers or producers must conduct research and development to promote consumer demand for Lycium chinense, and they must overcome any consumer-held negative images of Lycium chinense attributes.

Interest in smart cities is growing; information and communication technology, urban planning, urban economy development, health, and many other areas are intertwined within smart city research and practice. The definition of smart city is evolving, and its vagueness is sometimes confusing. This review of the smart city literature tries to capture the big picture of this big idea. This review places into context work done since 2016, as earlier work is well reviewed in Albino (2015) and Cochia (2014). First is a review of the various smart city definitions. Second, an inventory of terms related to or subsumed by the smart city label are presented. Third, outcomes of indexes created to measure a city's smartness are presented. Fourth, the taxonomies used to organize the disparate content that falls under the smart city umbrella are discussed. Fifth, the most recent literature associated with six commonly recognized subgenres, namely smart economy, smart governance, smart living, smart people, smart environment, and smart mobility are reviewed. Sixth, important critiques of the smart city idea are presented.

The purpose of this research was evaluated economical effect to apply alternative external carbon source. Conventional activated sludge process in municipal wastewater treatment plant was adapted and introduced to Biological nutrient removal processes to meet the newly enforced effluent quality standard for nutrient removal in Korea. Low $COD/NH_4^+-N$ ratio and higher nutrient concentration of influent characteristics force to inject external carbon source for denitrifying recycled nitrate. In the most case, methanol was used as external carbon source. But Methanol is expensive and very dangerous in handling. So we could find cheaper and safer external carbon source substituted methanol in last study. This alternative external carbon source is named RCS(recoverd carbon source) and a by-product of fine chemical product at chemical plant. When RCS was applied real municipal wastewater treatment plant, average $55\~65\%$ of T-N removal efficiency, 8.8mg/l of effluent T-N concentration, 11.3mg/l of effleunt COD concentration were obtained without effluent COD increase as against used methanol. To apply RCS in municipal wastewater treatment plant obtain approximately $\74.5%$ expenditure cost reduction in comparison with methanol dosage cost.

The purpose of this study was to develop an aloin-loaded wound dressing with an enhanced healing effect. The cross-linked hydrogel films were prepared with poly(vinyl alcohol) (PVA) and carboxyl methyl cellulose (CMC) using a freeze-thawing (F-T) method. Their gel properties, release of drug, in vivo wound healing effect and histopathology were then evaluated. In the wound healing test, this aloin loaded PVA/CMC hydrogel showed faster healing of the wound made in rat dorsum than the aloin carbomer 934 gel or the control (carbomer 934 gel) due to phytochemical activity of aloin and moisture of CMC. In conclusion, the aloin-loaded wound dressing composed of 5% PVA, 5% CMC and 0.125% aloin is a potential wound dressing with enhanced wound healing effect.

The purpose of this study is to examine the effects of nursing work environment and reciprocity on job embeddedness in the small and medium size hospital nurses. The data were collected from questionnaires filled out by 206 nurses. Data collection was performed from March 4 to 22, 2019. The collected data were analyzed by SPSS 25.0 program. As a result of the research, the study model accounted for 66.0% of job embeddedness. The most powerful variable affecting job embeddedness was support system of nurse, among sub - variables of nursing work environment. Therefore, nursing managers should improve the nurse's job embeddedness by creating nursing work environment that supports nurses such as salary improvement, professional development and promotion opportunities. In addition, it suggests that improvement of hospital and nursing organization system is needed to maintain cooperative relationship with nursing team or other health care professionals.
