하수관거시스템 개량의 주된 목적은 불명수(Inflow/Infiltration, I/I)를 제거함으로써 그 성능을 향상시키는데 있다. 이때 전체 하수관거시스템 내에서 개개 관거별 I/I 발생량을 정량화할 수 있다면, 전체 하수관거시스템 내에서 소유역별 해당 정보의 추출이 보다 명확해질 수 있다. 그러나 실제 현장에서는 예산 및 시간의 제약 때문에 개개 관거의 I/I 발생 정보의 획득은 거의 불가능하다. 본 연구에서는 하수 관거별 I/I 발생량을 AHP(Analytic Hierarch Process)를 이용하여 정량화하였으며, 산정된 관거별 I/I 발생량을 이용하여 효율적인 하수과거 개량 사업 시행을 위한 개량 우선순위 결정 모형(Rehabiliation Priority Decision Model for sewer system, RPDM)을 개발하였다. 개개 관거별 I/I 발생량 산정 결과에 기반하여 RPDM은 개량이 시행되는 기간 동안 발생하는 I/I 발생량을 최소화하는 소유역별 최적 개량 우선순위(Optimal Rehabilitation Priority, ORP)를 유전자 알고리즘을 이용하여 결정한다. 이때 최적 개량 우선순위에 따른 소유역별 개량 시행 시 발생하는 이익은 개량 기간 동안 하수처리장으로 들어가는 I/I의 하수처리비용(Waste Water Treatment Cost, WWTC)에 대한 절감을 의미한다. 본 연구에서는 개발된 RPDM에 의한 최적 개량 우선순위의 결과는 일반적인 하수관거 개량사업의 우선순위 결정 방법인 점수가중평가법(Numerical Weighting Method, NWM)과 최악의 개량순서에 따른 결과들과 비교되었으며, 개량 기간 동안의 I/I 처리비용이 점수가중평가법에 비하여 22%, 최악의 개량순서에 비하여 40% 감소하는 것으로 나타났다.

하수관거 개량사업의 주된 목적은 Inflow/Infiltration (I/I)를 제거 및 통수능력 확보이다. 최근 노후 하수관거의 개 보수 및 신설 사업이 활발히 이루어지고 있으나 현재의 사업들은 관거 데이터의 부족, 유량 및 수질 자료의 장기적인 측정 미비 등으로 인하여 효율적인 사업을 진행시키기에 무리가 있다. 본 연구에서는 하수관거 개량사업을 보다 효율적으로 진행시키기 위하여 Rehabilitation Weighting Model (RWM)과 Rehabilitation Priority Model (RPM)로 구성된 의사결정모형을 개발하였다. RWM은 시간 및 예산상의 제약으로 인하여 주요 지점에서만 관측되는 I/I를 상류의 각 관거별로 I/I를 산정하며, 관거별 I/I는 Analytic Hierarchy Process (AHP)를 통하여 산정된 8개 결함항목별 가중치에 따라서 결정된다. RPM은 Genetic Algorithm (GA)를 이용하여 소유역별 최적개량우선순위를 산정한다. 이것은 공사 기간 중 발생하는 I/I를 최소화시키기 위한 소유역별 공사 순서를 설정함으로써 하수처리장의 처리비용을 절감시킴으로써 하수관거 개량사업의 효율적인 시행을 위한 판단 기준을 제시해준다.

Purpose: A survey was conducted to investigate the role, priority, and awareness of physical therapists in the community care system for the elderly. Methods: Nine hundred ninety-three physical therapists were invited to an online survey from 1st to 30th June 2020. Results: While the awareness of physical therapists for the community care system for the elderly was found to be low, the role priority and performance ability were found to be high. Fall training scored the highest for the job duties of physical therapists, and functional training scored the highest for the performance ability of physical therapists. For the role priority by the education status regarding the community care system, the participants who received the education program showed higher scores in the performance ability than those who did not. For the role priority and performance ability according to the education levels, higher education levels resulted in higher scores in both outcomes. Regarding the clinical experience, low scores were found in the participants with less than five years of experience. Conclusion: Physical therapy establishes itself as an essential area of expertise in the community care system for the elderly. Therefore, these results can be utilized in developing a model for Korean community care for the elderly.

Objectives: Considering the importance of social determinants of health (SDHs) in promoting the health of residents of informal settlements and their diversity, abundance, and breadth, this study aimed to identify, measure, and rank SDHs for health promotion interventions targeting informal settlement residents in a metropolitan area in Iran. Methods: Using a hybrid method, this study was conducted in 3 phases from 2019 to 2020. SDHs were identified by reviewing studies and using the Delphi method. To examine the SDHs among informal settlement residents, a cross-sectional analysis was conducted using researcher-made questionnaires. Multilayer perceptron analysis using an artificial neural network was used to rank the SDHs by priority. Results: Of the 96 determinants identified in the first phase of the study, 43 were examined, and 15 were identified as high-priority SDHs for use in health-promotion interventions for informal settlement residents in the study area. They included individual health literacy, nutrition, occupational factors, housing-related factors, and access to public resources. Conclusions: Since identifying and addressing SDHs could improve health justice and mitigate the poor health status of settlement residents, ranking these determinants by priority using artificial intelligence will enable policymakers to improve the health of settlement residents through interventions targeting the most important SDHs.

Since sewer rehabilitation program requires long construction period and enormous capital investment, determination of rehabilitation priorities is important with systematic planning considering appropriate evaluation parameters. In this research, we applied PROMETHEE(Preference Ranking Organization METHod for Evaluations) known as very objective and scientific multi-criteria decision-making analysis, using the weights determined by AHP(Analytic Hierarchy Process) for the selected sewer evaluation items to calculate the rehabilitation priorities for each sewer sub-catchment in basin Gusan 1 of Seoul. Preference functions and preference thresholds were estimated for each criterion of ratio of lack of hydraulic capacity of sewers, defect ratio, ratio of sewers with velocity less than its minimum criteria, and density of sewers in the sub-catchment. As a result, it was found that region d had the first priority among four sub-catchments. For each and every sewer located in region d, we could also rank sewers to be rehabilitated urgently.

Purpose: This study attempted to understand patients' and nurses' perspectives on the priority of rehabilitation nursing services using Importance-Performance Analysis (IPA). Methods: This study used descriptive research design. Data were collected from 121 patients and 144 nurses using self-reported questionnaires. Statistical analysis included an independent t-test, analysis of variance (ANOVA), and IPA conducted using SPSS/WIN 21.0 version. Results: There were no statistical differences between the patients' and nurses' mean scores on perceptions of the importance (t=-0.83, p=.409) and performance (t=-0.32, p=.751) of rehabilitation nursing services. The IPA matrix showed a difference between patients and nurses in terms of their perceived priority of nursing services. Regarding the perception of patients, "helping a patient to continue to practice bedside physiotherapy and occupational therapy", "providing information on the proper care agency and community resources", and "providing education for the prevention of complications" fell in the "concetrate here" area (2nd quadrant). Conclusion: The results showed that the priorities of patients and nurses did not match in terms of some of the rehabilitation nursing services. Thus, rehabilitation nursing services need to be provided based on the patients' needs. Allocation of resources for the service items that fell in the "concentrate here" area of the IPA need be reconsidered for the quality in nursing care.

A long-term sewer rehabilitation project consuming an enormous budget needs to be conducted systematically using an optimization skill. The optimal budgeting and ordering of priority for sewer rehabilitation projects are very important with respect to the effectiveness of investment. In this study, the sewer rehabilitation optimization model using fast-messy genetic algorithm is developed to suggest a schedule for optimal sewer rehabilitation in a subcatchment area by modifying the existing GOOSER$^{(R)}$ model having been developed using simple genetic algorithm. The sewer rehabilitation optimization model using fast-messy genetic algorithm can improve the speed converging to the optimal solution relative to GOOSER$^{(R)}$, suggesting that it is more advantageous to the sewer rehabilitation in a larger-scale subcatchment area than GOOSER.

The purpose of the study is to establish priorities in integrated medicine policy. Delphi method was used in conducting a survey on integrated medicine specialists regarding the policies of integrated medicine and actions. For specialists in integrated medicine, total 17 persons selected included scholars who performed minimum one study on integrated medicine, medical staff who performing integrated medical service at institutions that implemented integrated medical care or those who were involved in creating or implementing policies on integrated medicine. The first Delphi-method survey conducted from Apr. 14 through 18, while the second survey was carried out from Apr. 21 through 25. To prioritize the policies based on the results of the mini Delphi-method survey, Analytic Hierarchy Process(AHP) was performed for 15 persons answered to mini Delphi-method from May 2 through 16, 2014. From the Delphi-method survey, four policies and 16 actions were obtained. AHP showed the first priority placed on 'Building the Infrastructure of Industrialization in the Integrative medicine' of the 4 policies and 'Developing new diagnostic and treatment instruments' was given the highest priority of the 16 actions. For implementation of integrated medicine policy, the 4 policies and the 16 actions found in this research require government support and should be urgently implemented according to its priority.

The objective of this study is to analyze the investment adequacy of the projects implemented according to the master plan on sewerage rehabilitation at Seoul. The planned and actually implemented ratio of invested money on sewage treatment plants (STPs) to sewers were compared in two temporal periods. Though the planned ratio of investment on STPs to sewers was 50:50 (in 2009-2020), the actual implemented ratio in 2009-2013 was 34:66. Until 2020, the greater investment ratio on STPs to sewers should be made considering the necessity of coping with stricter legal compliance on advanced treatment, stormwater treatment and so on. The priority of the planned and partially implemented projects among four STPs and at each STP was evaluated. Considering only the performance indicator of reduced load of BOD, T-N, T-P per the capacity of each STP facility, the performance among four STPs was shown as Jung-Rang>Tan-Cheon>Seo-Nam>Nan-Ji. The reverse order of the performance results in the past may be considered for future investment priority, but the efficiency of operation implemented at each STP, deteriorated status of each STP, investment in the past and so forth should also be considered. As for the priority of projects conducted within each STP, projects related to legal compliance (such as advanced tertiary treatment, stormwater treatment, etc.) have highest priority. Odor-related project and inhabitant-friendly facility related projects (such as building park on STPs, etc.) has lower priority than water quality related projects but interactivity with end-users of sewerage should also be important.
