This study was conducted to investigate the factors affecting stress before clinical practice among nursing students. The subjects of the study were surveyed on third-grade students who were about to undergo their first clinical practice. The data collection period was from December 22, 2023 to January 10, 2024, with a total of 191 nursing students. The instruments used for this study were Perceived stress scale(Pss), Self-leadership, and Global Interpersonal Communication Competency(GICC) scale. The data were analyzed by t-tests, ANOVA, Scheffé test, Pearson correlation coefficient, and multiple regression using SPSS/WIN 21.0. The results of the study showed a negative correlation with self-leadership(r=-.29, p=<.001) and interpersonal communication competence(r=-.40, p=<.001). In the stepwise multiple regression analysis, it was found that the stress levels of nursing students before clinical practice were influenced by factors such as gender, satisfaction with the department, and interpersonal communication competence. These variables explained 33.7% of the variance in pre-clinical stress. Based on the findings of this study, it is recommended to develop educational interventions that can help reduce stress before clinical practice among nursing students.

Lately, the rapid social and family system change, the entrance examination-centered circumstance in education have a negative influence not only on making up the affirmative self-esteem but also on building up the personal relationship through mutual communication with friends of the same age. Making children adapt well to school life and develop a good relationship in the class is an important subject in educational field. Thus, various school activities should offer lots of opportunities to increase their affirmative self-esteem and more specified performance-centered programs are required toform a harmonious relationship among parties of students. The purpose of this study is to improve an affirmative self-esteern and a desirable personal relationship of children through developing friend-praise program and adapting it to children. Based on the above purpose, the following subjects for this study 'are suggested. Firstly, is the friend-praise program effective in forming an affirmative self-esteem of elementary students? Secondly, is the friend-praise program successful in improving a desirable personal relationship in an elementary school? In addition, two hypotheses of study are decided on the basis of theoretical background and the former study. Hypothesis 1. The friend-praise program will have a meaningful effect on improving an affirmative self-esteem. Hypothesis 2. The friend-praise program will have a meaningful effect on improving a desirable personal relationship. In order to improve the above hypotheses, the experiment was carried out with two classes on the fourth grade in M elementary school in Wonju with being divided into one experimental group and the other comparative group. The friend-praise program which was adapted to the experimental group was composed with four steps as 'introduction', 'preparation', 'operation' and 'closing'. This program which has twelve categories was executed once or twice in a week and each class was continued for forty or sixty minutes. Contrastively, comparative group had no application of the main program. For the purpose of proving the hypotheses after adapting the program to students, I have executed both self-esteem test and personal relationship test. The tests were performed with using SPSS/Windows V10.0 and the statistic was conducted through independant sample t-test for the difference between groups and contrastive sample t-test for the individual difference in each group. The results of this study can be summarized like the followings: Firstly, from the result of previous and after tests, there was no meaningful change in the comparative group, but the experimental group showed meaningful difference in all categories of self-esteem(t=-4.496, p=.000). Especially, the general self-esteem(t=-3.216, p=.003), social self-esteem(t=-2.680, p=.012), homely self-esteem(t=-3.732, p=.001), and school self-esteem(t=-3.902, p=.000) showed a meaningful difference. At the same time, the experimental group also showed meaningful difference with the comparative group in self-esteem(t=-4.758, p=.000). Especially, the general self-esteem(t=2.581, p=.017), social self-esteem(t=3.160, p=.003), homely self-esteem(t=4.283, p=.000), and school self-esteem(t=4.110, p=.000) showed a meaningful difference. As a result of this experiment, the friend-praise program will have a meaningful effect on improving an affirmative self-esteem was proved. Secondly, there was no meaningful change in the comparative group, but the experimental group showed meaningful difference in all categories of personal relationship(t=-4.131, p=.000). Specifically, satisfaction(t=-2.113, p=.045), communication(t=-3.381, p=.002), confidence(t=-3.517, p=.001), intimacy(t=-3.958, p=.000), sensibility(t=-2.955, p=.006), openness(t=-4.318, p=.000) and interest(t=-2.941, p=.000) showed a meaningful difference. In the same instant, the experimental group also showed meaningful difference with the comparative group in all categories of personal relationship(t=3.897, p=.000). Especially, satisfaction(t=2.257, p=.003), communication(t=3.527, p=.001), confidence(t=3.704, p=.001), intimacy(t=3.904, p=.000), sensibility (t=4.382, p=.000), openness(t=2.648, p=.013) and interest(t=2.944, p=.006) showed a meaningful difference. Accordingly, the friend-praise program will have a meaningful effect on improving a desirable personal relationship was proved. Judging from all these results, we should provide primary students with various opportunities to take part in active programs which help them to set up their righteous sense of value, to solve their own problems and to develop their potentials. Consequently, many kinds of practice-centered program like the friend-praise program should be developed more systematically and teachers should apply all those programs to students according to their individual level and developmental stage.

This paper suggests optimal location algorithm of new firm $A(F_A)^{\prime}s$ p(p$B(F_B)$ already operating q outlets of sports in the market. This algorithm selects top q nodes among $V=V{\backslash}F_B$ nodes that covers maximum nodes based on the shortest distance. Then, q nodes choose next node that has a maximum cover with inclusion-exclusion principle. At the time of same number of cardinality in q sets to pre-defined q, we select the maximum cover node set. This algorithm called by competitive algorithm. The competitive algorithm simply decides the optimal location of the outlets p=1,2,3,4 for q=5. Also, we show that the market share of competitive algorithm can be maximize.

Recently, due to the rapid diffusion of intelligent systems and IoT technologies, power saving techniques in real-time embedded systems has become important. In this paper, we propose P-GA (Parallel Genetic Algorithm), a scheduling algorithm aims at reducing the power consumption of real-time systems in multi-core hybrid memory environments. P-GA improves the Proportional-Fairness (PF) algorithm devised for multi-core environments by combining the dynamic voltage/frequency scaling of the processor with the nonvolatile memory technologies. Specifically, P-GA applies genetic algorithms for optimizing the voltage and frequency modes of processors and the memory types, thereby minimizing the power consumptions of the task set. Simulation experiments show that the power consumption of P-GA is reduced by 2.85 times compared to the conventional schemes.

The purpose of this study was to analyze and compare head register with chest register of singers acoustically. Fifteen healthy tenor major students were participated. Fifteen healthy untrained adults were chosen as the control group for this study. Long term average (LTA) power spectrum using the Fast Fourier transform (FFT) algorithm and Linear predictive coding (LPC) filter response were made with /a/ sustained in both head (G4, 392 Hz) and chest registers (C3, 131 Hz). Statistical analysis was performed using the Mann-Whitney test. In the LTA power spectrum, head register of singers increased in the level of energy gain within the frequency of 2.2-3.4 kHz (p<0.01), and 7.5-8.4 kHz (p<0.01, p<0.05). Chest register of singers increased in the frequency of 2.2-3.1 kHz (p<0.01), 7.8-8.4 kHz (p<0.05) and around 9.6 kHz (p<0.01). The LTA power spectrum revealed a peak of acoustic energy around 2,500 Hz, known as the singer's formant and another peak of acoustic energy around 8,000 Hz in the singer's voice.

This study is a one-group pretest-posttest design to evaluate the effect of problem-based learning (PBL) for patient safety on self-leadership, patient safety competencies, and reflective thinking of nursing students. The research was conducted from March 2 to April 15, 2022, in which 57 nursing students participated. PBL for patient safety was examined in a total of 8 sessions in the order of motivation, problem identification, task performance planning, problem-solving methods, summary and solution, presentation, and evaluation. The following topics of patient safety were selected for each team: nursing records, high-alert medication, medication error and intravenous fluid regulation, blood transfusion care, fall, bedsore, infection control, and pain management. We provided feedback on the learning process and outcomes of nursing students. According to the results, self-leadership showed a statistically significant improvement in self-expectations (t=2.60, p=0.01), goal setting (t=2.84, p<0.01), self-reward (t=3.32, p<0.01), and self-criticism (t=2.32, p=0.02). Patient safety competencies showed a statistically significant improvement in patient safety knowledge (t=13.05, p<0.001) and patient safety skills (t=4.87, p<0.001) but not in reflective thinking. The results prove that PBL for patient safety is an effective teaching-learning strategy to improve self-leadership and patient safety competencies. Future studies must develop and validate specific and long-term teaching-learning methods to improve reflective thinking.

Privacy preservation is crucial in ubiquitous computing environment in which lots of privacy- sensitive information can be collected and distributed without appropriate control. The anonymity-based approach is a famous one used for privacy preservation communication, which allows users to use pseudonyms instead of real ID so as not to reveal their identities. This approach is effective in that it can hide the identity of users. However, it makes it difficult to provide ID-based services like buddy service, dangerous area alert, P2P communication in the ubiquitous computing. We proposes a system architecture which enables ID-based services in the ubiquitous computing environment employing anonymity - based privacy - preserving approach.
