Purpose: This study aims to explore the students’ experiences of taking class in nursing philosophy at the graduate school of nursing. Methods: Data were collected through individual in-depth interviews with 18 participants who took nursing philosophy class. Core question was 'What is your experience of taking nursing philosophy class?' Verbatim transcripts were analyzed using content analysis. Results: Qualitative data analysis revealed nine theme clusters in four categories; 'The distance from philosophy that is too far to be friendly’, ‘Finding the academic roots of nursing',’The way to find answers through creative insights' and ‘Presenting a vision of nursing through reflection and maturity'. Conclusion: Nursing graduate students initially encountered challenging thoughts and a sense of detachment from reality when they embarked on their nursing philosophy class. However, nursing philosophy classes are essential for uncovering the academic foundations of nursing science, fostering creative insights, and navigating the actual clinical fields. This is particularly crucial because nurses frequently encounter numerous ethical dilemmas and critical decision-making situations. Nursing philosophy classes should be mandated as a required course for nursing graduate students, as they are responsible for shaping the future of nursing scholars.

This study investigated the hazard factors based on imported food non-compliance and global food hazard information for the last 4 years to suggest imported food safety management. Food safety management on utensils or packaging containers is appropriately managed for the compounds derived from them. Food safety management on health-functional foods, processed foods, and agricultural products is concentrated on ingredient contents, food additives, and pesticide residuals. Additional hazards are illegal compounds, mycotoxins & pesticide residuals, hygieneindicator microorganisms and food-borne pathogens in health-functional foods, processed foods, and agricultural products, respectively. The continuous increase in hazards related to safety and hygiene in global food hazard information needs additional attention. To reduce the hazard factors, this study proposes that imported food be limited to products certified by HACCP or an equivalent food safety management system because registering foreign food facilities for processed and health-functional foods is mandatory. Additionally, the customs clearance inspections should focus on the hazard factors derived from the global food hazard information system. This study suggests a global food hazard information system that could derive frequently issued hazard factors at a given period and newly issued hazard factors in aspects, such as food items, subcategories, and exporting countries.

Aluminum material, which has excellent corrosion resistance, durability, and light weight, is widely used in the field of shipbuilding, and welding is an essential technology in shipbuilding. currently, welding is efficiently used to assemble structures of various sizes in the shipbuilding process, but aluminum is a very sensitive material at high temperatures and in a molten state, so appropriate process control is essential. research on aluminum welding has been continuously conducted, but most of the research is on the butt welding method. therefore, in this study fillet welding experiments, which are essentially applied to the internal structure of aluminum ships, were performed and the correlation between welding beads and process variables was identified. for the welding experiment GMA fillet welding was performed on Al5083 material used in the shipbuilding industry, and the influence of the process variable was confirmed by analyzing the correlation through the analysis of the etched fillet weld bead cross section for the test result according to the process variable.

The purpose of this study was to evaluate the effect of nutrition education on dietary knowledge, dietary attitudes, and dietary behavior of elderly by analyzing changes before and after nutrition education. This study was conducted in Seoul from March 2022 to December 2022 for 50 elderly (6 male, 44 female) who participated in nutrition education for 8 weeks at three senior welfare centers (Seodaemun, Seongbuk, Jongno). A total of 35 responses were used in the final analysis. Statistical analysis was conducted using descriptive statistics, paired t-test, and Wilcoxon’s signed rank test by age, hypertension, and dislipidemia to find effect of nutrition education on their nutritional knowledge, dietary attitudes, and dietary behavior. Results showed that nutrition education had a significant effect on the elderly. In particular, for those with chronic diseases such as hypertension and dislipidemia, the difference after education was significant, indicating significant changes in dietary habits. This study is expected to provide basic data for the development of a systematic nutrition education program for the elderly in the future.

Carbon steel pipes, which are essentially used in the manufacturing industry, are used in various fields due to the advancement of the industry, and a cutting process is essentially applied to pipes manufactured in a nominal size. The cutting process is the most basic and first process used to obtain a material in a desired shape, and it can affect the quality of subsequent processes such as welding or painting, so high-quality cutting surfaces are essential. Therefore, due to the advantage of improving productivity, it is essential to study to secure the appropriate quality of the cutting surface of the plasma cutting process, which is widely used in the industrial field. In this study, the effect of cut surface quality according to process parameters in the plasma cutting process for carbon steel pipe materials was analyzed. The surface roughness was measured to determine the quality of the cut surface, and the relationship between the surface roughness and the process variables was confirmed by selecting the arc current and cutting speed, which are identified as the main factors forming the surface roughness, as process variables.

국제사회는 글로벌 기후위기 극복을 위해 2050년까지 탄소중립(Net Zero)을 목표로 다양한 탈탄소 에너지원 개발을 지속하고 있다. 우리 정부에서도 ‘재생에너지 3020’ 정책을 수립하고 태양광이나 풍력을 이용한 에너지 개발계획을 추진함에 따라 해상 풍력발전단 지와 같이 연안해역에서 기존에는 볼 수 없었던 대규모 해양개발사업이 추진되고 있다. 해양시설물은 선박의 입장에서 볼 때는 항행 장 애물의 일종이며, 해양시설물 설치에 따라 좁아진 수역에서 선박 간 충돌사고 발생 또는 선박과 해양시설물의 접촉사고 발생시 환경오염 및 인명피해 등의 발생이 우려된다. 이에 국내외의 해상풍력발전단지 개발계획을 살펴보고 풍력단지에서 선박의 안전한 통항을 보장하기 위한 제도적 장치가 완비되어 있는지 분석하였으며, 해외의 입법 사례와 국내 법규를 비교하여 법적 사각지대를 해소하기 위한 새로운 법령안을 제안함으로써 대한민국의 관할해역에서 해양시설물의 안전한 운영과 선박의 안전한 통항을 기대하였다.
