1. Introduction : Research progresses in Chemistry and Chemical Engineering have been made during the last decades with important contributions to the industrial development and to the quality of our life. An interesting case is related to the membrane science and technology continuous impact to innovative processes and products, particularly appropriate for a sustainable industrial growth. Membrane operations have been familiar for many years to biologists and chemists working in their laboratorier or studying biological phenomena. Only recently engineers started to operate in' this area. The preparation of asymmetric CA membranes at University of California, Los Angeles in the early 60s is generally recognized as a crucial moment for membranology (1). Loeb and Sourirajan with their discovery of how to increase significantly the permeability of polymeric membranes without significant changes in their selectivity, made realistic the possibility of their use in large scale operations for desalting brackish and sea water by reverse osmosis and for various other molecular separations in different industrial areas. Reverse osmosis is today a well recognized basic unit operations, togheter with ultrafiltration, crossflow microfiltration,. nanofiltration, all pressure driven membrane processes. Already in 1992 more than 4 milIions m$^3$/day were the total capacity of RO desalination plants and in 1995 more than 180.000 m$^2$ of ultrafiltration membranes were installed for the treatment of wheys and milk (2) (3).

The rapid growth of economy improves not only the life quality of people in this modern society but also standards of value in connection with how those people would spend money as they engage in various leisure and cultural activities. That being the case, hotels are currently changing into places of new concepts depending on those new lifestyles of these people, and in those new places, people can entertain and experience as enjoying cultures. The marketing collaboration of the hotels with brands can be used as a more inclusive way to enhance brand images. In addition, as having infinite possibilities of the collaboration's being able to create a new-concept space with an identity of a brand included, this collaboration makes it possible for the design hotels to decorate their interior spaces differently from those of other hotels. In the light of that, the brand collaboration is basically divided into three groups which are the fashion collaboration, the technique collaboration and the designer collaboration, and the brand collaboration is also able to express the interior spaces of the design hotels as working on those six components, such as reproduction, events, alteration, messages, culture and image. After all, through the brand collaboration marketing, this thesis expects an interior design of a new-concept design hotel which would play a role as a complex cultural space.

To investigate the causes of Korea's growth slowdown over the past thirty years, we estimate the contributions of major developmental factors, including i) demographic factors (changes in population growth and workforce age due to the demographic transition), ii) quality-of-life-related choice factors (changes in working hours, education, and the female employment rate), iii) structural change, and iv) the effects of productivity catch-up. Our estimates show that these four groups of factors account for approximately 90 percent of the growth slowdown, with demographic factors contributing approximately 30 percent and the other three groups of factors each contributing about 20 percent. We also show that the same factors explain most of Korea's high growth in the 1980s. These results suggest that Korea's growth slowdown is basically a consequence of its successful economic development and that the high growth and subsequent slowdown can be regarded as a single process. In addition, given that the factors examined here exhibit similar patterns of change in the course of economic development of most countries, we think that our estimation results of the relationship between economic development and changes in economic growth trends could have more general implications that go beyond Korea's experience.

Purpose: This study is a descriptive research study to identify the relationship between the experience of verbal abuse, compassion fatigue, and work engagement among nurses in the emergency unit. Methods: Study subjects were 107 nurses working in a university hospital in Gyeonggi-Do. The instruments used were a verbal abuse checklist, a subscale of the Professional Quality of Life Scale used to measure compassion fatigue, and the Utrecht Work Engagement Scale. The data were analyzed using the IBM SPSS version 22.0 program for independent t-test, one-way ANOVA, and Pearson's correlation coefficients. Results: Emergency nurses experienced more verbal abuse and compassion fatigue than nurses in other departments, and the level of work engagement was low. There was a positive correlation between experience of verbal abuse and compassion fatigue and a negative correlation between both of these variables and work engagement. Particularly, verbal abuse appeared in the order of nurses, patients & caregivers, and doctors. This means there were serious problems with communication with nurses. Conclusion: In order to reduce verbal abuse, it is necessary to establish a communication culture of mutual respect between nurses, medical staff, patients & caregivers. Moreover, a compassion fatigue management program is needed to reduce emotional fatigue.

Purpose: More than 60% of patients with advanced cancer experience pain, and uncontrolled pain reduces the quality of life. Nurses are the closest healthcare providers to the patient and are suitable for managing cancer pain using pharmacological and non-pharmacological interventions. This study aimed to identify factors affecting the performance of cancer pain management among nurses. Methods: This study was conducted among 155 participating nurses working at a tertiary hospital who had experience with cancer pain management. Data collection was performed between October 18, 2021 and October 25, 2021. Data analysis was conducted using descriptive statistics, the independent-sample t-test, one-way analysis of variance, and hierarchical regression analysis. Results: There were 110 subjects (71.0%) who had no experience of cancer pain management education. The results of regression analysis indicated that barriers included medical staff, patients, and the hospital system for cancer pain management (𝛽=0.28, P<0.001). The performance of cancer pain management was also affected by experience of cancer pain management training (𝛽=0.22, P=0.007), and cancer pain management knowledge (𝛽=0.21, P=0.006). The explanatory power of the variable was 16.6%. Conclusion: It is crucial to assess system-related obstacles, as well as patients and medical staff, in order to improve nurses' cancer pain management performance. A systematic approach incorporating multidisciplinary interventions from interprofessional teams is required for effective pain management. Furthermore, pain management education is required both for cancer ward nurses and nurses in other wards.
