The purpose of this study was to investigate empathic ability, Nunchi, learning flow and clinical competency, and to identify the influencing factors on clinical competency of nursing students. Method: There were 179 nursing students as participants in K city, who were surveyed between May 10 and May 14, 2021, using a self-report questionnaire. Data were analyzed by frequencies, t-test, ANOVA, Pearson's correlation, multiple regression using SPSS Win 21.0. Result: There was a positive correlation between empathic ability and Nunchi(r=.148, p=.048) and between learning flow and clinical competency(r=.605, p<.001). In the multiple regression, Academic achievement(𝛽=.129, p=.049), Age(𝛽=-.116, p=.014) and satisfaction of clinical practice(𝛽=-.242, p<.001) were associated with clinical competency. These factors accounted for 38.4% of the total variance in clinical competency. Therefore, to improve clinical competency of online nursing practice of nursing college students, it is necessary to develop a specific strategy to improve academic achievement and to develop various activities and programs to immerse students in satisfaction of online practice.

The purpose of this study was to investigate the correlation between menopausal symptoms, perceived awareness of menopausal symptom, menopausal attitude and of menopausal management in middle aged women and to identify factors affecting menopausal symptoms. The subjects of study were 242 middle aged women who are living in G, J, K city and understood the research items and agreed to participate in the research. Data were collected from April 10 to May 30, 2019. Data were analyzed using t-test, ANOVA, Pearson's Correlation Coefficient and Stepwise Multiple Regression with SPSS/WIN 25.0. In this study, it was founded that perceived awareness of menopausal symptom(β=. 51, p<.001), menstruation status(β=. 23, p<.001), perceived health status(β=. 19, p=. 002), satisfaction of life(β=. 14, p=. 019) and religion(β=. 10, p=. 045) were found to be influential factors affecting menopausal symptoms in middle aged women. The most influential factor was perceived awareness of menopausal symptom. A nursing intervention program is needed to change positively the awareness of menopausal symptom.

Purpose: Blunt cardiac injuries (BCI) have a wide clinical spectrum, ranging from asymptomatic myocardial contusion to cardiac rupture and death. BCIs rarely require surgical intervention, but can be rapidly fatal, requiring prompt evaluation and surgical treatment in some cases. The aim of this study was to identify potential factors associated with in-hospital mortality after surgery in patients with BCI. Methods: The medical records of 15 patients who had undergone emergency cardiac surgery for BCI between January 2014 and August 2020 were retrospectively reviewed. We included trauma patients older than 18 years admitted to Regional Trauma Center, Gachon University Gil Medical Center during the study period. Clinical and laboratory variables were compared between survivors and non-survivors. Results: Non-survivors showed a significantly higher Injury Severity Score (p=0.001) and Abbreviated Injury Scale in the chest region (p=0.001) than survivors. American Association for the Surgery of Trauma-Organ Injury Scale Grade V injuries were significantly more common in non-survivors than in survivors (p=0.031). Non-survivors had significantly more preoperative packed red blood cell (PRBC) transfusions (p=0.019) and were significantly more likely to experience preoperative cardiac arrest (p=0.001) than survivors. Initial pH (p=0.010), lactate (p=0.026), and base excess (BE; p=0.026) levels showed significant differences between the two groups. Conclusions: Initial pH, lactate, BE, ventricular injury, the amount of preoperative PRBC transfusions, and preoperative cardiac arrest were potential predictors of in-hospital mortality.

As one of the key parameters to determine $CO_2$ flux between air - sea interface, it is quite important to know p$CO_2$, which has involved much uncertainty, mainly due to the complex variations of sea surface p$CO_2$ and the paucity of samples, made in ocean. In order to improve the interrelationship between partial pressure (p$CO_2$) and different physical and biochemical parameters in global sea surface water, a new empirical relation is established to correlate and parameterize p$CO_2$ in the mixed layer using the data from recent WOCE cruises. Meanwhile, by new empirical relation, abundant historical hydrographic and nutrients ship data, Levitus data set and NOAA/AVHRR(SST), p$CO_2$ have been accumulated and applied. Then effort has to be made fur promotion of this study to correlate and parameterize p$CO_2$ in the mixed Layer with different physical and biochemical parameters. and further attribute this huge historical data sets and NOAA/AVHRR(SST) data to estimate p$CO_2$. In this paper we analyzed more interrelationship between the model and ship/satellite data set. Finally, the inter-annual variations of p$CO_2$ in sea are presented and discussed.

To evaluate the role of obesity and nutrient intake on serum IGF-1 and serotonin levels in 80 elementary school children (aged 10. 8 yr, 47 boys, 33 girls), we investigated the anthropometric data and the nutrient intake by questionnaries including food daily record, and measured serum IGF-1 and serotonin using RIA and HPLC F-1050 respectively. We obtained the following results by obesity index (underweight-, normal-, obese group). The protein intake of normal group was higher than the others (p < 0.05). The underweight and obese groups had snacks more often than the normal group. The obese group preferred‘cookies’and‘fries’more than the other groups. The serum serotonin levels showed weak correlation with fat (r = 0.315, p < 0.01), fiber (${\gamma}$ = 0.280, p < 0.05) and energy intake (r = 0.242, p < 0.05), but no differences in anthropometric data by obesity index. The serum IGF-1 level was significantly correlated height (r = 0.649, p < 0.001), weight (r = 0.437, p < 0.001) and hip (r = 0.417, p < 0.001), but showed weak correlation with energy intake (r = 0.232, p < 0.05) and carbohydrate intake (r = 0.244, p < 0.05). In this study, we could see only partly correlation among the serum IGF-1 and serotonin and obesity and nutrient intake. Forker research is required into consideration of the essential role of these hormones during a growth period.

The effect of toxicants on ecological systems is an important issue from mathematical and experimental points of view. Here we have studied dynamical model of a single-species population-toxicant system. Two cases are studied: constant exogeneous input of toxicant and rapidly fluctuating random exogeneous input of toxicant into the environment. The dynamical behaviour of the system is analyzed by using deterministic linearized technique, Lyapunov method and stochastic linearization on the assumption that exogeneous input of toxicant into the environment behaves like ‘Coloured noise’.

For the purpose of investigating the effect of evaluation on career support by the college and career exploration efficacy of dental hygiene students on the career exploration behavior, a survey was conducted in December 2014 with students of dental hygiene at universities located in Ulsan and Daegu as subjects. In the result, correlation was found among sub-factors of evaluation on career support by the college, career exploration efficacy, and career exploration behavior. Increase of career exploration efficacy (${\beta}=0.702$, p<0.001), practical career support (${\beta}=0.165$, p<0.05), and relationship establishment efficacy (${\beta}=0.152$, p<0.05) led to increase of career exploration behavior, while increase of individual exploration efficacy (${\beta}=.0.242$, p<0.001) led to decrease of career exploration efficacy. Therefore, it is necessary to build appropriate value system related to job seeking, conduct active discussions to increase relationship establishment efficacy by using interpersonal relationship reinforcement program, and expand career support program by the college.

Soil management for environment-friendly agriculture depends on the effects of soil microbial activities and soil fertility. To improve soil health for the upland crops, this study evaluated a relationship between soil chemical properties and soil microbial diversities at 25 sites in upland soils in Gyeongnam Province. The average nutrients in the upland soils were 1.7 times for available phosphorous, 1.4 times for exchangeable potassium and 1.5 times for exchangeable calcium higher compared to recommend concentrations in the upland soils. We found a significant positive correlation between the soil organic matter and the soil microbial biomass C (p<0.01). Contents of organic matter and dehydrogenase in the inclined piedmont soils were significantly higher than those in the other topographical soils (p<0.05). In addition, concentrations of organic matter and microbial biomass C in the loam soils were significantly higher than in the silt loam soils (p<0.05). In principal component analyses of chemical properties and microbial populations in the upland soils, our findings suggested that available phosphorous should be considered as potential factor responsible for the clear upland soils differentiation. The soil organic matter was positive correlation with Bacillus sp. and fungi, whereas soil pH was also positive correlation with Pseudomonas sp. in upland soils.
