This research is a descriptive study that aimed to identify the health knowledge related stroke, optimistic bias, and social support of middle-aged adults and the effect these had on their health-promoting lifestyle This study was conducted by collecting 220 adults aged between 40 to 60 years from C City D city and K city. Data were analyzed using descriptive analysis, ANOVA, t-test, Pearson's correlation coefficients and multiple regression with the SPSS 23.0 program. The average health-promoting lifestyle was 44.27 points. The health-promoting lifestyle of the study participants showed a positive correlation between the optimistic bias(r=.18, p=.001) and social support(r= .61, p<.000). According to the results of multiple regression analysis, perception of Necessity for Stroke Education(β=.12, p=.010), optimistic bias(β=.18, p=.040), and social support(β=.48, p<.000) were shown to be significant factors that affected the health-promoting lifestyle of the participants. These variables explained 38.5%. Therefore, an health education program to improve the health-promoting lifestyle related to stroke in adults should be considered as a way to enhance social support and reduce optimistic bias.

The age and growth of the skipjack tuna Katsuwonus pelamis were determined using otoliths sampled from a Korean tuna purse seine fishery in the Western and Central Pacific Ocean from January 2005 to September 2006. A total of 312 otoliths were used to estimate the ages of skipjack tuna, which ranged from 1 to 7 years. The relationships between otolith ring radius (R) and fork length (FL) for female, male, and sex combined were FL = 19.74R + 1.50 ($r^2=0.54$), FL = 17.66R + 6.35 ($r^2=0.47$), and FL = 18.83R + 3.36 ($r^2=0.53$), respectively. The back-calculated fork lengths of each age ($FL_{year}$) were $FL_1=36.2cm$, $FL_2=43.3cm$, $FL_3=48.3cm$, $FL_4=52.6cm$, $FL_5=56.5cm$, $FL_6=60.8cm$, and $FL_7=63.2cm$. The relationships between fork length (FL) and total weight (TW) for female, male, and sex combined were $TW=0.00001FL^{3.19}(r^2=0.95)$, $TW=0.00001FL^{3.17}(r^2=0.95)$, and $TW=0.000009FL^{3.23}(r^2=0.95)$, respectively. The von Bertalanffy growth parameters of skipjack tuna estimated in this study were $L_{\infty}=77.4cm$, K = 0.176/year, and $t_0=-2.569years$.

Harnesses are used in a variety of industries, such as rescue operations, medicine, and entertainment. However, conventional harnesses have problems as they are uncomfortable to wear and causes continuous pain. Therefore, in this study, the load and pressure applied to the body in the flying state when using a conventional harness were measured in real time and the distribution change was observed. Load and pressure were measured using a modified corset harness, a pressure sensor, and a human mannequin to measure the maximum and average pressure on the waist. As a result, it was confirmed that the load concentrated on the waist in the flying state was 104 N, and the pressure was applied to the left and right sides was 800 kPa or greater. The pressure distribution showed a pressure of 3-45 kPa in 73% in all measurable pressures. The results of the load and pressure distribution are presented as basic data for improving the wearability and reducing the discomfort of harnesses in the future, aid in the development of a harnesses that can minimize discomfort for various activities, and increase the concentration on experiential activities. In addition, using the CLO 3D program, which is a 3D virtual wearing system, a harness was put on a virtual model, and the compression level was checked and compared with the actual pressure distribution. As a result of comparing the measured pressure values in the flying state with the clothing pressure wearing the harness in the CLO 3D program, the total pressure value was found to be about 68% of the actual measured value. This helps develop a harness that can minimize discomfort during activities by predicting the load and pressure on the body by first applying new designs to a virtual wearing system during development. These new harness patterns can solve the problems of conventional harnesses.

This study was conducted to investigate the characteristics of oviposition and the effect of density suppression by yellow-colored sticky trap on Ricania shantungensis in blueberry. The occurrence of an egg mass of R. shantungensis in the upper, middle and lower region were 56.6~60.2%, 23.8~28.1% and 11.7~19.7%, respectively. The number of egg masses in the branch was investigated. Percentage of the branch with one egg mass was greatest (50.9%) than with two (20.5%), three (14.6%) and over four (14.0%). The effect of yellow-colored sticky trap to reduce the number of R. shantungensis egg masses in blueberry was also investigated. In a month after yellow sticky trap installation, 17.1 adults of R. shantungensis were attracted per trap. Moreover, the number of egg masses on a tree in yellow-colored sticky trap plot was much lower (0.4) than control (1.3). Consequently, this result shows that use of yellow-colored sticky trap may contribute to decrease ovipisotion rate of R. shantungensis in blueberry.

Purpose : This study sought to determine the influence of nursing students' self-leadership, empathic ability, and depression on their interpersonal skills. Methods : This study applied a descriptive survey research design involving a self-report questionnaire. The participants were 315 nursing students in B city. Data were collected from April 27 to May 6, 2022. The data were analyzed using the percentage, mean, standard deviation, t-test, ANOVA, Scheffé test, Pearson's correlation coefficients, and multiple regression with IBM SPSS/WIN 23.0 program. Results : The participants' self-leadership score was 3.63±.65, their empathic ability score was 3.35±.40, their depression score was .84±.50, and their interpersonal skills score was 3.64±.80. Among the sub-categories, others' temperament scored the highest at 3.70±.86, followed by communication at 3.67±.86 and promoting relationships at 3.53±.86. Interpersonal skills were positively correlated with both self-leadership (r=.48, p<.001) and empathic ability (r=.33, p<.001). Self-leadership was positively correlated with empathic ability (r=.17, p<.05), but, negatively correlated with depression (r=.27, p<.001). The multiple regression analysis revealed, that the factors with the most significant effect on promoting relationships were, in descending order, self-leadership (β=.49, p<.001), empathic ability (β=.19, p<.001), and gender (β=.10, p=.033); the factors affecting others' temperament were, in descending order, self-leadership (β=.37, p<.001), empathic ability (β=.30, p<.001), severe depression (β=.14, p=.008), gender (β=.13, p=.010), and grade (β=-.13, p=.037); while the factors affecting communication were, in descending order, self-leadership (β=.41, p<.001), empathic ability (β=.23, p<.001), and gender (β=.11, p=.035). Moreover, the explanatory power of promoting relationships scored the highest at 31 %, followed by others' temperament at 27 % and communication at 26 %. Conclusion : The results of this study reveal the factors that influence the interpersonal skills of nursing students. To increase the interpersonal skills of nursing students, it is necessary to develop and apply regular curricula and programs designed to strengthen their self-leadership and empathic ability and to reduce their depression through reflecting differences between genders and grades.

The use of synovial fluid-derived mesenchymal stem cells (SFMSCs) obtained from patients with degenerative arthropathy may serve as an alternative therapeutic strategy in osteoarthritis (OA) and rheumatoid arthritis (RA). For treatment of OA and RA patients, autologous transplantation of differentiated MSCs has several beneficial effects for cartilage regeneration including immunomodulatory activity. In this study, we induced chondrogenic differentiation of SFMSCs by inhibiting protein kinase A (PKA) with a small molecule and microRNA (miRNA). Chondrogenic differentiation was confirmed by PCR and immunocytochemistry using probes specific for aggrecan, the major cartilaginous proteoglycan gene. Absorbance of alcian blue stain to detect chondrogenic differentiation was increased in H-89 and/or miRNA-23b-transfected cells. Furthermore, expression of matrix metalloproteinase (MMP)-9 and MMP-2 was decreased in treated1 cells. Therefore, differentiation of SFMSCs into chondrocytes through inhibition of PKA signaling may be a therapeutic option for OA or RA patients.

Purpose: This study was conducted to identify the effects of a prepared childbirth education on the knowledge and delivery participation levels of the spouses of primiparas. Method: The study's subjects were a convenience sample of 126 spouses, consisting of an experimental group of 74 educated for prepared childbirth for 10 hours. This study was measured by using a 41-item measurement instrument for knowledge of childbirth that was devised from Kang's(1981) instrument and a 23-item measurement instrument for measuring delivery levels which was developed through clinical experiences. The data gathered as analyzed by using SPSS WIN10.0. Result: There were no significant differences between the experimental group and the control group in homogeneity concerning the general characteristics of the spouses of primiparas. The first hypothesis, which stated that the level of knowledge of childbirth in the experimental group who received prepared childbirth education would be higher than in control group, was statistically supported by the Compared Independent Sample t-test(t=17.92, p=.000). The second hypothesis, which stated that the level of participation of delivery in the experimental group who received prepared childbirth education would be higher than in the control group, was also statistically supported (t=28.87, p=.000). The third hypothesis, which stated that there would be a correlation between the level of knowledge and the level of participation in the experimental group who received prepared childbirth education, showed a high positive correlation(r=.810, p=.000). Conclusion: The above results indicate that the increase of knowledge through prepared childbirth education in the spouses of primiparas has a high correlation with delivery partici- pation levels which engenders physical and moral support for primiparas at delivery. Additionally, a varied prepared childbirth education acts as an effective means to increase under- standing and support for primiparas couples who experience tension, anxiety and fear due to an unprepared delivery in Korea.
