This study aimed to investigate the relationship between the nutrition quotient and the dietary intake of adolescents. A total of 393 adolescents were surveyed to evaluate their Nutrition Quotient for Korean Adolescents (NQ-A) scores and dietary intake. The average age of the survey subjects was 15 years and the average NQ-A score of the subjects was 49.11±13.35. There was no significant difference in the NQ-A scores according to gender and age. The average dietary diversity score was 3.77±0.85, and it was significantly higher in boys than in girls (p< .05) with the scores of 12-14-year-old students being significantly higher than those aged 15-18 years (p< .01). The results of comparing the percentage of recommended intake or adequate intake and the mean adequacy ratio (MAR) according to the NQ-A grade, showed that the ‘High’ grade had a significantly higher intake percentage of vitamin B1, B12, folate, phosphorus, iron and a significantly higher MAR (p< .05). From a long-term perspective, efforts to improve dietary habits are deemed necessary to meet an individual’s nutritional requirements. Adolescents themselves should develop proper eating behaviors and acquire suitable dietary management skills to enhance their nutritional status, ultimately contributing to an improvement in their quality of life.

A checklist of dietary behavior items for the elderly was developed based on Korean dietary guidelines. First, a literature review was conducted, and 63 preliminary items, including 30 items on food intake, 12 on eating habits, and 21 on dietary culture, were obtained to evaluate the dietary guidelines. The preliminary items were evaluated by experts using Lawshe’s method to verify the content validity. They were then revised, resulting in 52 items: 25, 11, and 16 in the food intake, eating habits, and dietary culture domains, respectively. A face-to-face survey was conducted on 331 people over 65 years of age in the metropolitan area, and their one-day food intake was surveyed using a 24-hour recall method in August 2022. The 48 items, including 24, 11, and 13 items on food intake, eating habits, and dietary culture, respectively, correlated significantly with the evaluation indicators of nutrient intake, such as mean adequacy ratio, dietary diversity score, and nutrient intake density. These items were considered suitable for evaluating the elderly's compliance with dietary guidelines.

Purpose: This study aims to develop a simulation module equipped with scenario-based core nursing skills and test the effects after applying the simulation education based on a developed scenario. Method: This was a nonequivalent control group pre-/posttest design study, and 114 nursing students participated from April 1 to August 30, 2018. The applied scenario-based core nursing skills simulation module was developed in the order of planning, development, application, and evaluation according to the Dick and Carye Model’s program development process. Knowledge, self-efficacy, stress, and nursing practice were measured before and after intervention in two groups: an experimental group that performed a simulation after applying the scenario-based core nursing skills, and a control group that performed a simulation after applying core nursing skills. Results: Knowledge (F=23.19, p<.001), self-efficacy (F=25.83, p<.001), and nursing practice (t=9.51 p<.001) increased in the group that performed a simulation after applying the scenario-based core nursing skills, whereas stress (F=40.41, p<.001) decreased. Conclusion: Various education methods should be applied to increase the education effect of the simulation, Simulation performance can be used as an alternative to improve nursing practice during simulation education.
