Purpose: The purpose of this study was to investigate the status and characteristics of visiting nurses' management for elders with cognitive impairment living in a community focused on health centers in a metropolitan city and five medium-sized cities. Methods: Data were collected from 47 visiting nurses working in a metropolitan city and 47 visiting nurses working in five medium-sized cities from November to December 2012. Results: There were no statistically significant differences in knowledge, attitudes, and nursing behaviors of cognitive impairment between two groups (F=2.13, p=.148; F=3.64, p=.060; F=0.28, p=.595). Among the elders referred to a physician in a metropolitan city by visiting nurses, 42.4% were diagnosed as mild cognitive impairment and 15.2% were diagnosed as severe dementia. The major intervention programs which visiting nurses currently applied for elders were medication and exercise intervention programs, and the intervention programs which they would want to apply in the future were playing, music and recall intervention programs. Conclusion: The cognitive impairment screening test can be done effectively by visiting nurses. This study also suggests to develop various kinds of intervention programs to improve cognitive function for elders living in a community.

Objectives : This study was performed to investigate the injury rates and risk factors for preschool children in Daegu city and Kyungpook province. Method : A questionnaire survey about medically attended injuries during the preschool period was performed in nine primary schools located in Daegu city, Pohang city and Goryung County. The overall injury rate was estimated using person-year. The causes and patterns of the injuries, and their risk factors were examined. Result : A total of 469 medically attended injuries were reported in 330 of the 959 study subjects during the preschool period. The overall annual injury rate was 7.5 per 100 children. The injury rate increased sharply during the period from infant (2.4) to 1 year of age (7.5), and the peak injury rate (9.2) was reported for 5 year olds. The most common causes of injuries were falling (36.0%), followed by being struck by an object (23.7%), and traffic accidents (14.1%). Among the traffic accidents, 72.8% occurred while playing on the road, riding a bicycle or roller-skating. A proportional hazard model showed that males (hazard ratio=1.49, p<0.001 compared with female) and the mother's higher education level (hazard ratio of college or higher= 1.51, p=0.013; high school=1.32, p=0.085 compared with those of middle school or lower) were significant risk factors of childhood injury. Conclusion : The results of this study suggested that efforts for children's safety should be made, especially from the toddler stage, and in male children. To develop a more specific childhood injury prevention program, a surveillance system for injuries should be established. Further study of the relationship between mother's occupation and injury rates is also needed.

Purpose : This study aimed to demonstrate the effects of visiting cognitive activities using brain training on cognition, subjective memory complaints and depression among elderly participants residing in community living in Gwangmyeong city. Methods : Over a 14-month period (October 2022 to December 2023), four brain training instructors visited the homes of older adults and conducted the intervention using a brain training kit. The participants included 32 elderly individuals aged 65 years and older, who were living in Gwangmyeong city. The assessments were conducted by an occupational therapist, a nurse and a social worker at the Gwangmyeong dementia relief center. These assessments included the following the subjective memory complaints questionnaire (SMCQ), short geriatric depression scale-Korean (SGDS-K), a cognitive impairment screening test (CIST), the consortium to establish a registry for Alzheimer's disease-Korean (CERAD-K). The participants were divided into three groups (A: 20-30 points, B: 10-19 points, C: 1-9 points) based on the CIST score. For data analysis, descriptive statistics and wilcoxon signed-rank test were performed using SPSS 24.0, and the statistical level was at a=.05. Results : The results of the intervention showed that the SMCQ score of group A improved significantly (p<.05), the CIST score of group B also improved significantly (p<.05). However, the SGDS-K score of group C improved, but did not demonstrate statistical significance (p=.080). Conclusion : The visiting cognitive activities using brain training produced significant effects on cognition, depression, and subjective memory disorders, depending on the cognitive level of the elderly participants. In the future, it will be necessary to demonstrate the effects according to cognitive level in various aspects with more elderly people.

A survey of the Chundong valley forest in Mt. Sobaek was conducted using 20 sample plots of 500$m^2$ size. The classification by TWINSPAN and DCA, CCA ordination techniques were applied to the study area in order to classify them into several groups based on woody plants and environmental variables. By TWINSPAN techniques, the plant community were divided into four groups. The dividing groups are Pinus densiflora community, Qurcus variabilis -Q. mongolica -P. densiflora community, Fraxinus rhynchophylla community. The successional trends of tree species by DCA ordination techniques and DBH class distribution analysis seems to be from P. densiflora through Q. mongolica. Q. variabilis to F rhynchophylla. The correlation between the score of first two axes and soil pH, soil humus, soil calcium concentration, soil magnesium concentration was significantly positive in CCA ordination. The positive correlation between the score of first two axes of F. rhynchophylla community and soil humus, soil magnesium concentration and between ones of P. densiflora community and soil pH were calculated. But there is no correlation between species and environmental variables.

Purpose: The purpose of this study was to seek ways to improve the quality of life of workers by separating workers into the low fatigue group and the severe fatigue group depending on the level of fatigue level, and analyzing and understanding the difference between quality of life and job stress according to the fatigue level. Methods: For the 'Development of Mibyeong management system which was a consumer-directed health care service', the data of job stress, fatigue and quality of life was collected from 115 workers who visited the oriental hospitals located in J city and C city from Jul, 2012 to Dec, 2012. Results: The severe fatigue group showed significantly higher job stress than the low fatigue group in physical environment (p=.004), job demand (p<.001), interpersonal conflict (p=.012), lack of reward (p=.062). The severe fatigue group showed lower degrees both in physical component summary (PCS) (p<.001) and mental component summary (MCS) (p<.001) measured by SF-12 and the quality of life (p<.001) measured by EQ5D than the lower fatigue group. A relatively strong negative correlation was found in the item of mental component summary (MCS) measured by SF-12. Conclusion: Considering our results that high fatigue level show negative impact on quality of life and job stress, we suggest to provide a variety of health promotion strategies to improve the quality of life through the prevention and relief of fatigue for workers.

School gardens are known to be effective for increasing vegetable consumption in children. This study was carried out to examine the perception of garden program leaders for actual conditions and barriers to promote school gardens according to their sense of dedication. The 49 garden program leaders at schools and child care centers in Pocheon city were surveyed and grouped into two groups: dedicated (57.1%) and less dedicated (42.9%) as program leaders. Compared to dedicated leaders, leaders in the less dedicated group less advocated promotion of school gardens (P<0.001) and were less willing to attend training for school garden (P<0.01), despite less experience as program leaders (P<0.01) and past training (P<0.05). Moreover, leaders in the less dedicated group less acknowledged the educational results of school garden in every aspect (P<0.001, respectively), less perceived support from parents and colleagues (P<0.05, respectively), and less used garden produce in more active activities such as donation and literature (P<0.05, respectively), compared to the dedicated group. The most answered barrier against the promotion of school gardens was work burden, followed by manpower shortage, shortage of technique, knowledge, and information, and time shortage. The results of this study provide evidence that developing strategies is needed to make more teachers and child care providers more dedicated as garden program leaders.

This study was undertaken to analyze the growth, nutritional, and dietary risk factors of elementary school students belonging to the Busan Metropolitan City Office of Education and provide the basic data needed to develop an underweight and obesity prevention program. In 2021, BMI and Dietary Screening Test (DST) data of 4,046 children surveyed by the Nutrition Education Experience Center's "Diagnosis System" of the Busan Regional Office of Education were analyzed. The DST consists of 36 questions about lifestyle habits, meal quality, meal regularity, snack quality, and eating behavior. Of the children included, 6.8% were underweight, 65.4% were normal weight, 13.4% were overweight, and 14.4% were obese. Children in the obesity group had shorter sleep and meal times (P<0.001), lower vegetable and fruit consumption frequencies (P<0.001), higher fast food consumption frequencies (P<0.001), higher rates of skipping meals (P<0.01) and breakfast (P<0.001), and more frequently used smartphones and watched TV during meals (P<0.001). The underweight group had the highest scores for all eating development factors but more frequently had chewing and swallowing difficulties (P<0.001). The study confirms underweightedness and obesity are present different problems and indicates that nutrition teachers should conduct accurate studies on the eating habits and behaviors of obese and underweight students and provide individually tailored nutritional counseling.
