This study was attempted to predict the direction for ward nursing work through robotic systemization. Robot systems have not been universalized due to difficulties in operation, space constraints, and high prices. The robotic systemization should be focused on the robotic systemization of simple and repetitive tasks. The idea of a robot system for measuring vital signs and a robot system that helps bed sheet exchange is worth discussing with the engineering field. In addition, for successful nursing and interdisciplinary convergence, a detailed analysis of nursing work is required, and in order to overcome the trial and error of convergence, it is necessary to establish a converging society between nursing and interdisciplinary systems. Robotic systemization of successful ward nursing work will not only generate profits for hospitals, but also raise the status of nurses and will be the starting point for innovation in nursing work.

Cellulases are a group of biocatalyst enzymes that are capable of degrading cellulosic biomass present in the natural environment and produced by a large number of microorganisms, including bacteria and fungi, etc. In the current study, we isolated, screened and characterized cellulase-producing bacteria from soil. Three cellulose-degrading species were isolated based on clear zone using Congo red stain on carboxymethyl cellulose (CMC) agar plates. These bacterial isolates, named as HB2, HS5 and HS9, were subsequently characterized by morphological and biochemical tests as well as 16S rRNA gene sequencing. Based on 16S rRNA analysis, the bacterial isolates were identified as Bacillus cerus, Bacillus subtilis and Bacillus stratosphericus. Moreover, for maximum cellulase production, different growth parameters were optimized. Maximum optical density for growth was also noted at pH 7.0 for 48 h for all three isolates. Optical density was high for all three isolates using meat extract as a nitrogen source for 48 h. The pH profile of all three strains was quite similar but the maximum enzyme activity was observed at pH 7.0. Maximum cellulase production by all three bacterial isolates was noted when using lactose as a carbon rather than nitrogen and peptone. Further studies are needed for identification of new isolates in this region having maximum cellulolytic activity. Our findings indicate that this enzyme has various potential industrial applications.

Background: Research in environmental health (EH) is of crucial strategic importance for contemporary society. It is becoming even more critical in light of the increasingly rapid pace of environmental changes, opportunities, and threats. Objectives: This study aimed to identify trends and the prospective of environmental health research using SWOT analysis. Methods: The trends in environmental health research were reviewed in previous studies and reports. Reviewed manuscripts were searched for using the keywords of 'environmental health' and 'environmental hygiene' in the KCI (Korean Journal of Citation Index), KISS (Korean Academic Information), PubMed, and Google Scholar. Results: It is essential to center the EH research agenda around key priorities focusing on technological innovation, job creation, and the increasingly prominent role of the private sector. Given the rapidly evolving global sustainability agenda, greater clarity on the ever-increasing sources of complexity and growing expectations of the public might be needed. This requires the identification of criteria to identify EH research priorities with the ultimate goal of maximizing societal benefit. Public health relevance, such as extent and severity of health impact, level of exposure, and inequalities of effects, could be included. Conclusions: Considering the recent interest in and importance of environmental health, a comprehensive approach to environmental health research should be required through the application of the latest science and technology, citizen participation, and environmental health surveillance systems.

Most universities are attempting educational innovation through multidisciplinary approaches, such as interdisciplinary programs and convergent majors, to nurture convergent talents in the era of the 4th Industrial Revolution. The purpose of this study is to identify the priorities of the educational needs of students who complete the interdisciplinary program and to find its effective operation plan. For this purpose, research was conducted to search for the university-level support required to vitalize the interdisciplinary program by doing focus group interviews with students who have participated in the interdisciplinary program. And the final priority was derived by applying the t-test, Borich's need assessment model, and The Locus for Focus Model, using online research. As a result of the analysis, 'formation and operation of dedicated organizations' and 'dedicated classrooms and practice rooms' were deduced as factors to be considered as a top priority, 'curriculum specialization,' 'interdisciplinary program scholarship support,' 'interdisciplinary program promotion,' and 'assignment of dedicated teaching assistants' were derived as secondary consideration factors. Based on these research results, a plan of vitalizing the educational needs for the interdisciplinary program at university and its implications were suggested.

The purpose of the present study was to evaluate the thermal insulation of air-filled winter jackets according to the amount of air-filler using a thermal manikin. The insulation of these jackets' was compared to a down padded jacket with an identical design and size. The amounts of air-filler were 100% (26,219 cm³), 70% (18,645 cm³), 50% (13,110 cm³), and 0% (0 cm³). The results showed that a clothing insulation (Icl) of 0%, 50%, 70%, and 100% air, and 100% down jackets was 0.208, 0.243, 0.207, 0.176, and 0.315 clo, respectively. In addition, the down jacket with waisttaped had a clothing insulation of 0.369 clo. However, the highest value of clothing insulation per clothing weight was the 50% air-filled jacket in all conditions. In terms of regional power consumption of the thermal manikin, the down jacket consumed less power for the shoulder and chest than the air-filled jackets. In conclusion, in order to maximize the thermal insulation of air-filled jackets, an optimal amount of air-filler, that is, an amount which does not compromise (break) the layer of inner air between the surface of manikin and the lining of the jacket, should be explored. Further studies on lining materials, end-closed design, and changes in thermal insulation under the conditions of strong wind or heavy snow are recommended.
