The purpose of this study was to analyze the factors that affect the satisfaction of smart seniors using smartphone delivery applications. We established the hypothesis by dividing the factors that will affect the satisfaction of smart seniors using smartphone delivery applications into the characteristics of the delivery app and the personal characteristics of the smart senior. In order to verify the hypothesis, we surveyed adult men and women aged 50 to 65 years old who had experience using delivery apps, and we performed confirmatory factor analysis, correlation analysis, and path analysis to perform statistical processing for data analysis. The analysis results are as follows. First, we found that usefulness among the characteristics of delivery app had a statistically significant positive effect on the delivery app satisfaction of smart seniors. Second, we found that social empathy among the personal characteristics of smart seniors had a statistically significant positive effect on the delivery app satisfaction of smart seniors. Third, we found that delivery app satisfaction had a statistically significant positive effect on reuse intention. Based on research result, we suggested that in order to improve the satisfaction and use of delivery app by smart seniors, it is necessary to develop delivery app that can be usefully used by smart seniors and focus on social empathy.
The purpose of this study is to propose an effective informatization policy by categorizing consumer groups according to the level of digital divide and identifying the characteristics of each type. For this end, a total of 402 data were collected through an online and on-site surveys targeting consumers with internet experience, and the data were analyzed using the SPSS 26.0 program. As a result of conducting a K-means cluster analysis based on access to, capability, and utilization of digital devices, four consumer groups were categorized: 'device lover', 'proficient user', 'general user', and 'digital alienated'. By consumer type, significant differences were found in demographic characteristics, social capital, perception of the future information society, attitude toward technology as innovativeness, discomfort and familiarity, which are the antecedent variables of the digital divide. Significant differences in digital device satisfaction and intention to use, which are outcome variables of the digital divide, were also confirmed by consumer type. This study is academically and practically valuable in that it proposes customized informatization policies for each consumer group according to the level of digitization.

This study was conducted to examine the influence and effect of muscle enforcement program on Activity of daily living(ADL) improvement and posture balance of the old, and to provide more effective muscle enforcement program and educational data. The muscle enforcement exercise program was performed on the old(institution, 16 men, 10 women) for 8 weeks from April 22, 2002 through June 17,2002. Programed Exercise 1 - Exercise 10 were practised 8 times per program for 3 days a week. The load of exercise was increased per two weeks. The methods of measurement were questionnaire, Indiana 47903(action-response analysis machine) and Sample exercise protocol for KAT 2000(balance training device). SAS/PC statistic analysis was used for data analysis. T-test was used for analysis of change before and after exercise in this study. The summary and conclusions are as follows. 1. On subjectively recognized health states, the healthy were $42.3\%$. On the satisfaction with health states, the satisfied were $50.0\%$. On the factors of effects on daily-life behavior performance, the group who had troubles was $50\%$ and the group who was so and so was $34.6\%$ compared with the old of the same age. On prospect about health states in the future, the group who would be better was $38.\%$. On effective methods for problem solving, exercise was $42.3\%.\;88.5\%$ of respondents answered the need of health care. The participation intention in health program was $92.3\%$. 2. On the change of psychological emotion and behavior aspects, the group who had repeated complaints or anxieties and reduced activities or interests was effective(P<0.01). 3. On the improvement effects of IADL difficulties, the group who had difficulties in doing daily-life indoors was improved effectively compared with before and after exercise(P<0.01). On medication management, the effects of improvement after exercise were high compared with before exercise(P<0.01), the effects of improvement was high on the whole. 4. On the effects of ADL function improvement, putting on upper clothing and lower clothing was improved effectively(P<0.05), toilet use and individual sanitation was improved effectively(P<0.05). 5. On the effects of action-response, the results of 8weeks regular exercise program were not different significantly compared with before and after exercise. The behavior quickness of the old by muscle enforcement program was not increased. This means that the old needs much time for exercise sense training because of the regression of cognition sense. 6. In the effect of posture balance, the whole grades were effective from 1272.69 before excercise to 476.92 after exercise(P<0.01). Especially right balance 657.65 was lowered to 208.57 after exercise most effectively(P<0.01). Rear balance 776.34 before exercise was lowered to 136.65 after exercise. The results of measurement were significant(P<0.05).
The purpose was to contribute substantially in terms of marketing strategic planning and implementation of coffee shops. Additionally, the target was set as the favorite coffee shops on the basis of the young people. Through the IPA Matrix, subdividion variable was derived and by using the variables in each quadrant, tested the variables that have significant effect on satisfaction, reuse, and recommendation intentions. The study results showed that there was a significant difference in the importance performance (IPA) difference analysis of coffee shop service quality elements and this proved that empirically, the expectations were different. Additionally, it was evident that there were statistically significant and not statistically significant elements in the relationship between service quality element and the overall satisfaction rate in each elements shown in the IPA. Through this, it was possible to provide the information on what service quality elements to focus and distribute. It was possible to understand that the ultimate goal should be satisfaction since the overall satisfaction positively affects the reuse and intention of recommendation and it was possible to re-confirm the previous studies which stated that overall satisfaction, reuse, and recommendation intentions have a positive influence.
The purpose of this study is to look into practical knowledge of geography teacher that lead the teacher's conduct in performance assessment situation. In Classroom all activity of teachers is their unique creature and the behavior which express teacher's knowledge and competency as expert. Practical knowledge can be seen as a system of understanding that guides the teacher s decision, which involves the construction of contents to teach, methods of instruction, resources to use etc. Therefore if we fully read the teacher's instruction, we have to understand the practical knowledge of teacher. As an ordinary activity of teaming and teaching, performance assessment is conducted on active learning and teaching situation and has intention to advance learning. Thus All evaluating behavior conducted by teacher can be understood through the practical knowledge of teacher. For this purpose a series of performance assessment scenes conducted by teacher were selected observed and captured the imagery, principles and rules of practical knowledge through the qualitative research method. The result supposed that practical knowledge influence the whole process of geography teacher's performance assessment activity.

The emergence of compact and low-power wireless communication sensors and actuators in the technology supporting the ongoing miniaturization of processing and storage allows for entirely the new kinds of embedded systems. These systems are distributed and deployed in environments where they may have been designed into a particular control method, and are often very dynamic. Collection of devices can communicate to achieve a higher level of coordinated behavior. Wireless sensor nodes deposited in various places provide light, temperature, and activity measurements. Wireless sensor nodes attached to circuits or appliances sense the current or control the usage. Together they form a dynamic and multi-hop routing network connecting each node to more powerful networks and processing resources. Wireless sensor networks are a specific-application and therefore they have to involve both software and hardware. They also use protocols that relate to both applications and the wireless network. Wireless sensor networks are consumer devices supporting multimedia applications such as personal digital assistants, network computers, and mobile communication devices. Wireless sensor networks are becoming an important part of industrial and military applications. The characteristics of modem embedded systems are the capable of communicating adapting the different operating environments. In this paper, We designed and implemented sensor network system which shows through host PC sensing temperature and humidity data transmitted for wireless sensor nodes composed wireless temperature and humidity sensor and designs sensor nodes using embedded system with the intention of studying USN.
Objectives : The purpose of this study is to identify differences between suicide attempters who used zolpidem and others who used different methods in emergency department. Methods : This study classified 2,734 suicide attempters, who went to emergency department from 2009 to 2018, into zolpidem user group, another drug user group and non-drug user group. For these three groups, chisquare test and logistic regression analysis were conducted regarding sociodemographic feature and clinical feature related with suicide. Results : In the result of logistic regression analysis of a variable, which showed meaningful difference between suicide attempter group who used zolpidem and the other group who did not use the drug, the occurrence of zolpidem-using suicide attempers was related with the case where anxiolytics/hypnotics was used or the case where lethality and intention was low. In the drug intoxication group which showed similar feature, there was also a relevance between anxiolytics/hypnotics and the occurrence of zolpidem-using suicide attempts. Conclusions : This study identified significant difference of sociodemographic and clinical feature in suicide attempter group who used zolpidem and the other group. This result can contribute to plan further medicinal treatment in using zolpidem.
The intention of this study was to confirm the possible use of an ethanol extracts of Nelumbinis Rhizomatis Nodus (NRN) as a cosmetic material. To this end, we extracted NRN with 70% ethanol and performed biological activity evaluation of whitening efficacy and wrinkle reduction. We performed cellular tyrosinase inhibition and melanin contents assay to check the whitening activity of NRN and carried out a toxicity evaluation of NRN via an MTT assay and the amounts of associated proteins that affect melanin production in a melanoma cell line (B16F10). And collagenase inhibitory assay was performed for the evaluation of anti-wrinkle of samples. In addition, a toxicity evaluation using an MTT assay and matrix metalloprotease (MMP-1) and procollagen synthesis inhibition by NRN were evaluated in a fibroblast cell line (CCD-986sk). Western blot results for the whitening activity evaluation revealed that the levels of two proteins related to melanin production, tyrosinase-related protein-1 (TRP-1) and tyrosinase-related protein-2 (TRP-2), were decreased in a dose-dependent manner. Moreover, collagenase inhibition activity at a concentration of $500{\mu}g/ml$ NRN by measuring epigallocatechin-3-gallate (EGCG) was increased by more than 80% compared to the control group. Meanwhile, procollagen synthesis was reduced by 68.8% in the UVB-induced CCD- 986sk cells group whereas collagen synthesis recovered by 80.2% with $25{\mu}g/ml$ NRN. The MMP-1 expression rate showed 20.2% reduction at $25{\mu}g/ml$. The results of the experiments verified the whitening and wrinkle suppression effects of NRN and confirmed that it could be used as a safe natural cosmetic material in the future.

This study aims to understand the research landscape of South Korea using the data of 2020 Google Scholar Metrics. To achieve the goal, we constructed and analyzed four types of networks including the university collaboration network, the keyword co-occurrence network, the journal citation network, and the discipline citation network. Through the analysis of the university collaboration network, we found major universities such as Seoul National University, Keimyung University, and Sungkyunkwan University that have led collaborative research. Job related keywords such as job change intention and job satisfaction have been frequently studied with other keywords. Through the analysis of the journal citation network, we found multiple journals such as The Journal of the Korea Contents Association, Korean Journal of Sociology, and Korean Journal of Culture and Social Issues that have been widely cited by the other journals and influenced them. Finally, Education, Business administration, and Social welfare were identified as the top influential disciplines that have influenced other disciplines through the knowledge diffusion. The study is the first of its kind to use the data of Google Scholar Metrics and conduct a stepwise network analysis (e.g., keyword, journal, and discipline) to broadly understand the research landscape of South Korea. Our results can be used by government agencies and universities to develop effective strategies of promoting university collaboration and interdisciplinary research.
