  • Accurate quantitative precipitation estimation plays an important role in hydrological modelling and prediction. Instantaneous quantitative precipitation estimation (QPE) by utilizing the weather radar data is a great applicability for operational hydrology in a catchment. Previously, regression technique performed between reflectivity (Z) and rain intensity (R) is used commonly to obtain radar QPEs. A novel, recent approaching method which might be applied in hydrological area for QPE is Long Short-Term Memory (LSTM) Networks. LSTM networks is a development and evolution of Recurrent Neuron Networks (RNNs) method that overcomes the limited memory capacity of RNNs and allows learning of long-term input-output dependencies. The advantages of LSTM compare to RNN technique is proven by previous works. In this study, LSTM networks is used to estimate the quantitative precipitation from weather radar for an urban catchment in South Korea. Radar information and rain-gauge data are used to evaluate and verify the estimation. The estimation results figure out that LSTM approaching method shows the accuracy and outperformance compared to Z-R relationship method. This study gives us the high potential of LSTM and its applications in urban hydrology.

  • This study aimed to explore the moderating effect of social support resources on the life satisfaction and caregiving burden of family caregivers taking care of the elderly in long-term care services. The study participants were selected from among the family caregivers utilizing 30 home care centers in Seoul, Korea. Of the candidates who agreed to participate in the study, 250 caregivers who had supported the elderly at home for at least 6 months were selected. The data collected were analyzed using SPSS ver. 21.0. The study findings were as follows. First, the whole family caregivers' caregiving burden of family caregivers was found to be slightly higher than the median value. More specifically, the physical burden was the heaviest, followed by the family relationship burden, the social activity burden, the emotional burden, and the financial burden. Social support resources and life satisfaction were found to be a little bit higher than the median value. Second, the variables that statistically significantly increased life satisfaction, starting with the strongest effect, were a lower psycho emotional burden, greater informational support resources, a lower economical burden, greater emotional support, a younger caregiver age, a higher monthly income, and a shorter care period. Third, informational support resources were found to have a moderating effect on the relationship between the support burden and life satisfaction. The more the participants used the informational support resource subcategory of the social support resources, the narrower the life satisfaction decrease, even though the caregivers felt a support burden. Informational support resources appear to have a statistically significant buffering effect.

  • Global warming affects critical natural resources, one of which is the oceans that occupy 70% of the total cover of the earth. In other words, ocean warming is a subset of global warming which needs to be addressed urgently. Purple laver (pyropia spp.) is one of the most vulnerable items to climate change although it is a major export product of Korean fisheries. The purpose of this study is to analyze the causality of how climate change caused by global warming affects the increase or decrease of PLP (purple laver production). The target area for analysis was set to Maro-hae between Jindo-gun and Haenam-gun. We selected marine environmental factors and meteorologic factors that could affect PLP as variables, as well as co-integration tests to determine long-term balance, and the Granger causticity tests. As a result, PLP and marine environmental factors WT (water temperature), pH, and DO confirmed that long-term equilibrium relationships were established, respectively. However, there is only causality with WT and it is confirmed that there is only a correlation between pH and DO (dissolved oxygen). There was no long-term equilibrium relationship between PLP and HDD (heating degree days) and there is a causal effect that HDD affects PLP; however, it was less clear than that of WT. The relationship between PLP and RF (rainfall), WS (wind speed), SS (percentage of sunshine), and FF (farm facilities) was all balanced in the long term, and causality exists. Based on the results of the analysis, policy proposals were made.

  • The purpose of this study was to identify the effect of compassion competence on communication behavior of long-term care hospital nurses caring for patients with cognitive impairment and the mediating effect of resilience in the process. The data collection period was from September 27, 2021 to October 22, 2021, and the subjects were 131 long-term care hospital nurses in P city. The collected data were analyzed using the SPSS WIN 25.0 program, and descriptive statistics, pearson correlation coefficient, and multiple regression were performed. As a result of the study, first, it was found that there was a significant positive correlation between compassion competence and communication behavior(r=.625, p<.001), resilience and communication behavior(r=.535, p<.001). Second, resilience was verified as a partial mediating in the relationship between compassion competence and communication behavior(Z=2.012, p=.042). Therefore, in order to improve the communication behavior of nurses, it is suggested to develop and apply a program that can enhance compassion competence and resilience.

  • This paper critically examines the role performance of local distributors within the Stimulus-Organism-Response (SOR) model, while also considering the moderating influence of market competition on the organism (O) and response (R) elements. Adopting a holistic approach, the SOR model provides a comprehensive framework for analyzing how external stimuli, including distributive, procedural, and interaction unfairness, interact with internal psychological processes, such as perceived unfairness, to shape the long-term orientation of importing agents. Moreover, this study acknowledges the pivotal role of market competition in the operational context of local distributors. It posits that competitive market dynamics play a crucial role in intensifying the relationship between behavioral factors and the long-term orientation of distributors, thereby revealing contingent effects within the SOR model. Through the exploration of these dynamics, this study contributes to a comprehensive understanding of the interplay among external stimuli, internal psychological processes, and market competition within the SOR framework, advancing our knowledge in this field.

  • The importance of university technology transfer has widely been brought to the center of attention over the last decades. Research and practice thereby often concentrate on issues related to patenting and licensing or entrepreneurship but abstract away from relationship- and network-focused initiatives. In this paper, we argue that efforts to systematically develop close, long-term collaboration partnerships - although complex and resource intensive - are likely to be more beneficial for both universities and industry in the long run. Drawing on data derived from interviews with technology transfer executives of 22 leading European and U.S. universities, we analyze and discuss well-established practices of network and relationship management and their possible impact on technology transfer success. Our findings indicate that dedicated relationship management approaches can yield a sustainable competitive advantage for universities. We thereby shift the focus away from transaction-orientation towards more forward-looking relationship-centric approaches and discuss their institutionalization in great detail.

  • This study is aimed to analyze the impact of the perception of fairness on the relationship quality as a way to enhance the competitiveness through the establishment of a long-term relationship between food service franchisors and franchisees. An empirical analysis found that the more positively the fairness of franchisors is recognized, the more positive impact it has on the relationship quality. As both the distributive fairness and the procedural fairness, the two concepts of fairness, are perceived in a more positive manner, the trust and satisfaction over franchisers were found to be higher, with the conflict shown to be lower. Though both the distributive fairness and the procedural fairness showed a significant result, the procedural fairness, in particular, has a greater impact on the trust and satisfaction over franchisers than the distributive fairness. In addition, the quality of relationship between franchisor and franchisees has a positive impact on a long-term commitment. That is that as their trust and satisfaction over franchisors are higher with less conflict, franchisees will become more cooperative with their franchisors. The greatest impact on the long-term unity, among the factors that constitute the relationship quality, appeared to be trust. Accordingly, it is advisable persons in charge at franchisors place the greatest focus on fostering trust to establish a long-term relationship, inducing it in a positive direction. From such result, suggestions can be made in establishing a strategy for developing an appropriate relationship between food service franchisors and franchisees. Firstly, persons in charge at food service franchisors will have to induce the perception of franchisors' procedural fairness by franchisees in a positive direction in order to enhance the Quality of relationship with franchisees. Secondly, as an alternative strategy for forming a long-term relationship between franchisors and franchisees, the effort should be made to foster a greater trust in franchisors first. In many cases, franchisors currently focus more on their convenience in management than the development of systems to satisfy the franchisee needs. This contravenes with the essence of relationship marketing and thus, it can be said it is the most important of all that focus should be directed at trust and fairness in the effort toward a sustained relationship between franchisors and franchisees in the future.
