The occurrence of harmful algae on the coast of Korea has been a cause of damage to the aquaculture industry and deterioration of the coastal ecosystem environment. A method is required to predict their outbreak in real-time at the site. Therefore, this study attempted to develop a small hybrid optical sensor and real-time monitoring system based on LiDAR that can be used in the field and laboratory and can be applied to various platforms. FMS-L specifically suggested the amount of Chlorophyll a (Chl a) in the sample by measuring and analyzing the fluorescence emitted by the irradiating light. The accuracy of FMS-L was verified by measuring the concentrations of standard Chlorophyll a substances and Margalfidinium polykirkoids. In addition, the precision was verified by comparing the measurement results of FMS-L using commercial equipment Phyto-PAM-II. This equipment is compact and easy to move. Therefore, it can be easily applied to field surveys, allows short time measurements (10 s), and can be applied at a distance of 10 m from the measurement site.

Hypersonic engine test facility with ejector system was tested. Ejector system was designed by revised EJSIMP code. The performance of the ejector system was predicted by numerical analysis. As a result, ejector system satisfied the facility design requirement. Based on the pressure level, the facility was successfully started at Mach 3.5 and 20km altitude condition.

Purpose: The remarkable progress in information and communication technology has had a great effect on the healthcare delivery system. The development of smart phone applications is a new field. The aim of our research was to provide assistance in developing smart phone applications for community health nursing. Methods: Based on an informative approach, this study developed persona and site maps, followed by a storyboard as a way of analyzing users' requirements and designing responses in the context of smart phone application development methodology. Results: We developed persona, user interface and database design successfully, and then seven nurses selected four nursing problems (income, residence, pain, and digestion hydration). The search time in seconds for the 2005 English OMAHA guidelines to find three nursing interventions for these problems was used to evaluate the effectiveness of the smart phone application. The results showed that smart phone applications' search was 21 times faster on the average than book guidelines. Conclusion: An English version of the OMAHA system application was developed for the Android smart phone market. It is hoped that smart phone applications such as this will be used internationally for nursing education.

Purpose: The aim of this study was to compare between performance and requirements of visiting nursing care in long-term care insurance using the OMAHA system. Methods: The subjects were 72 nurses who had worked in a visiting nursing care center in long-term care insurance. Data were collected from December 5, 2016 to January 31, 2017 using self-recorded questionnaires. The collected data were analyzed using descriptive statistics and paired t-tests. Results: Four dimensions of the OMAHA system showed statistically significant differences between performance and requirements of visiting nursing care in long-term care insurance. The requirements of visiting nursing care were higher than was performance on all 40 items of the OMAHA system. The greatest difference was in environmental domain and then the psychosocial domain. Conclusion: Based on the results, we found that the environmental and psychosocial domains were the largest gap areas. Therefore, with the reality of elderly people living alone and the increase in elderly couples, active intervention connected with the community is needed in residential areas. Further, we suggest that the OMAHA system can be utilized as an integrated conceptual framework for developing and enhancing visiting nursing care in long-term care insurance.

Purpose: This study was done to report nursing case for ADL improvement of elders who have CVA(Cerebrovascular Accident) sequelae. Methods: The client had registered in the C visiting nursing center after being decided a long-term care Grade 2. Data were collected through consultation logs for recipients, Activities of Daily Living (ADL) records, fall risk assessment (Huhn) sheets, decubitus ulcer risk assessment (Braden Scale) sheets, cognition assessment (K-MMSE) sheets, long-term care benefit provision records, and interviews with visiting nurse. Data were collected and analyzed according to the Omaha System problem classification. The intervention scheme and the problem rating scale for performance were applied to present the case for home-visit nursing. Results: The client registered in August, 2018, was provided home-visit nursing care once a week as of September 2020. ADL, cognitive levels and decubitus ulcer risks were found to have improved. Conclusion: This case report presents the value of classifying nursing problems and checking nursing intervention provided to patients with problems of ADL. The presentation of home-visit nursing cases applying a standardized nursing problem classification scheme for clients with various problems showed that a high quality level of care is guaranteed and evidence-based nursing can be provided by visiting nurses.

Purpose: This case report was attempted to present the process of the end of life nursing care provided by the visiting nurse. Methods: The subject was a person who was decided the long-term care Grade 1 and received a visiting nursing service, and the service was terminated on the death, and then was selected as a case with the consent of his family. The data were collected through long-term care benefit provision records and interviews with the visiting nurse. The nursing process was presented by applying the Omaha System. Results: The subject had digestion-hydration problems and respiration problems in the physiological domain, and the problems of role change, caretaking/parenting, spirituality, and grief in the psychosocial domain were identified. Depending on the problem, the end of life nursing care was provided to the subject and family members through activities on physical symptoms/signs, dietary management, end-life care, and coping skills. Conclusion: We expect that if the visiting nurse provides anticipatory guidance on the death process, the subject will be able to prepare for death comfortably with the family at home instead of vague fear of death.

Purpose: This study sought to determine the possibility of developing the data-sharing infrastructure of an integrated information system to improve the quality of home and visit-based healthcare services. Methods: The articles of study here were the forms used by a visiting healthcare agency, a home healthcare system of a home healthcare agency, and those used in long-term care insurance for elderly. We visited a visit-based healthcare agency and a home healthcare agency to survey their forms and interviewed relevant practitioners, and we searched for forms associated with long-term care insurance for the elderly on the Internet. We then organized the terms in each form and mapped them among the form after analyzing the concepts as a whole to inquiry into the possibility of integration. Results: The mapping procedure divided the terms into those related to personal information, problems and interventions. Mapping between the standard system (Omaha system) and the type of form was also done. Conclusion: In this study, we found that programs were configured differently depending on the objectives of the service. It is necessary to develop the program with an integrated information system by comparing the three services in terms of their distinct advantages, after which such a service should be utilized. The results of this study can serve as a database for the creation of a new integrated system.
