This research uses the Balanced Scorecard framework to create comprehensive performance indicators for foodservice programs in senior welfare centers. The study evaluates these programs in South Korean senior welfare centers from financial, customer, learning and growth, and internal business process perspectives. Thirty-five evaluation indicators were developed and validated through the Delphi study used for the survey study nationwide, and 115 were collected. Thirty elderly welfare centers participated in on-site evaluation by the expert. The results of the survey study, 81.4, indicate overall favorable performance, with social workers scoring slightly lower than dietitians and directors. On-site evaluations showed better performance, 84.4, compared to the survey study. The learning and growth perspective showed a significantly higher score on on-site evaluation, and the score was 20.9, which was 3.1 points higher than 17.8 from the survey study (p<0.001). However, there is room for improvement, including adopting nutrition management programs, defining roles for dietitians and cooks, enhancing food sanitation regulations, and providing financial support. Additional recommendations involve recruiting nutrition personnel, collaborating with local governments, and integrating centers for children’s foodservice management at the local level. This research provides valuable insights into enhancing the foodservice in elderly welfare centers to improve the nutrition and well-being of the elderly population.

Conventional aquaculture faces declining productivity, shifting to recirculating aquaculture system (RAS), known for minimizing water usage and maintaining consistent water temperatures for year-round fish growth. Rainbow trout (Oncorhynchus mykiss), a globally important cold-water species and the third most farmed fish in inland waters of Korea, valued for its fecundity and rapid growth. Dissolved oxygen, an important environmental factor affecting fish production and economics, highlights the need for smart aquaculture practices. Since 2018, the rise of intelligent aquaculture platforms, incorporating information and communications technology (ICT), emphasizes the essential role of RAS implementation. This eight-week study aimed to determine the optimal dissolved oxygen concentration for rainbow trout in RAS, utilizing a device for continuous monitoring, control and record. Dissolved oxygen concentrations were set at 5-6 mg/L, 9-10 mg/L, 14-15 mg/L and 17-18 mg/L. The growth rate significantly decreased at 5-6 mg/L, with no significant differences in other experimental groups. In hematological analysis, growth hormone (GH) was significantly highest at 5-6 mg/L, followed by 9-10 mg/L while Insulin-like growth factor-1 (IGF-1) was significantly lowest at 5-6 mg/L. In conclusion, the optimal dissolved oxygen concentration for rainbow trout in RAS is approximately 9-10 mg/L. Higher concentrations do not contribute to further growth or profitability.

최근 우리사회에서 젠더갈등이 지역, 이념, 세대와 더불어 새로운 갈등 으로 부상하는 가운데 20대 대통령선거를 통해 유권자의 관심이 집중되 었다. 본 연구의 목적은 청년세대 남녀 간 갈등으로 취급되었던 젠더갈 등 이슈가 20대 대통령선거에서 쟁점으로 부각되면서 유권자의 주요 정 당 대통령후보에 대한 평가와 투표선택에 어떤 영향을 주었는가를 경험 적으로 분석하는 것이다. 당시 논쟁이 되었던 젠더갈등 이슈로 여성가족 부 폐지를 비롯해 여성할당제 폐지, 여성 병역의무화, 남성 육아휴직이 며, 주요 정당의 대선후보 평가를 후보 호감도와 국정운영 능력 평가로 분석한 결과 윤석열 후보와 이재명 후보의 호감도와 국정운영 능력 평가 전반에 지속적으로 영향을 미친 젠더갈등 이슈는 여성가족부 폐지였다. 또한 여성가족부 폐지 외 두 후보의 평가에 영향을 준 젠더갈등 이슈는 여성 병역의무화와 남성 육아휴직이었다. 마지막으로 두 후보에 대한 유 권자의 투표결정에 영향을 준 젠더갈등 이슈는 여성가족부 폐지로, 여성 가족부 폐지가 유권자의 대선 후보자에 대한 전반적인 평가는 물론 투표 선택에도 결정적 영향을 준 선거의 쟁점 이슈임을 여실히 증명했다.
