This study was conducted to identify factors affecting patient safety management (PSM) of nursing student's who have experienced clinical practice. The study subjects were 232 nursing students in five universities in five cities. Data were collected between June 17 and July 30, 2019 using by completing structured self report questionnaires. Data were analyzed using T-test, ANOV A, Pearson's correlation coefficient, and multiple regression using SPSS/WIN 22.0. In correlation ana lysis, significant positive correlations were found between PSM practice, PSM importance awareness (r= .42, p<.001), PSM knowledge(r= .29, p<.001), and PSM attitude(r= .35, p<.001). In multiple regressi on analysis, PSM importance awareness(β=.19, p<.001) was factor predicting PSM practice of nursing students, which explained 36.2% of the variance in the model. Thus, we emphasize that continuing PSM education at the university is required to improve PSM competency.

Purpose: This descriptive study aimed to identify the contribution of nurses' communication styles, nurse-mother partnerships, and mothers' anxiety levels to the coping of mothers of hospitalized children, with the goal of establishing effective intervention strategies based on these factors. Methods: Data were collected using a structured questionnaire from July 12 to October 29, 2018. The study's participants were 200 hospitalized children's mothers in the pediatric ward of a university hospital. Results: The coping of hospitalized children's mothers showed a significant relationship with nurses' informative communication style (r=.26, p<.001), affective communication style (r=.28, p<.001), nurse-mother partnership (r=.50, p<.001), authoritative communication style (r=-.28, p<.001), and mothers' anxiety (r=-.23, p=.001). A multiple regression analysis (adjusted R²=.32) indicated that the factors affecting the mothers' coping included nurse-mother partnership (𝛽=.47, p<.001), another caregiver (yes) (𝛽=.17, p=.006), and mothers' subjective health status (very healthy) (𝛽=.15, p=.047). Conclusion: Considering that the formation of cooperative partnerships between mothers and nurses found in this study had a positive effect on the mothers' coping skills, it appears necessary to develop and implement programs for improving nurses' communication skills and ability to form partnerships, beginning from undergraduate education.

The purpose of this study was to provide basic information for developing effective marketing strategies of nursing organization by identifying the correlation among internal marketing factor, nurses' job satisfaction, and organizational commitment. The subjects of this study were 256 nurses who were working in the hospital over 1 year at three university hospitals which had more than 400 beds in seoul and kyung-gido. The data were collected by self-reporting questionnaires. The instruments used in this study were the communication form scale developed by Jo(1995), the welfare scale developed by researcher, the education training scale developed by researcher, the organizational commitment scale developed by Mowday, Porter and Steers(1979). The data were analysed by the SAS package using frequency, percentage, mean, standard deviation, and Pearson's correlation coefficient. The results of this study were as follows; 1. Mean scores of internal marketing factors in nursing organization were as follows; horizontal communication 3.42, downward communication 3.32, involvement communication 3.08, upward communication 3.00, education training 2.54, welfare 2.51. The mean score of job satisfaction was 2.79 and organizational commitment was 3.00. 2. Job satisfaction was positively correlated with education training (r=0.54, p=0.0001), upward communication(r=0.49, p=0.0001). welfare (r=0.40, p=0.0001), horizontal communication(r=0.33, p=0.0001), involvement communication(r=0.25, p=0.0001) of internal marketing factors in nursing organization, but negatively correlated with downward communication(r=-0.16. p=0.0082). Organizational commitment was positively correlated with upward communication(r=0.48, p=0.0001), education training (r=0.42, p=0.0001), horizontal communication(r=0.36, p=0.0001), welfare (r=0.34, p=0.0001), involvement communication(r=0.25, p=0.0001) of internal marketing factors in nursing organization. but negatively correlated with downward communication(r=-0.20, p=0.0014). In conclusion. the results of this study showed that the internal marketing factors were highly correlated with nurses' job satisfaction and organizational commitment. Therefore, for nurses' job satisfaction and organizational commitment's improvement, it is important to develop the education training program. to improve welfare system and to actualize upward communication. among internal marketing factors.

The ultrasonic pulse velocities of pressure, shear, and Rayleigh waves ( P-, S-, and R- waves) have been used for the condition evaluation of various concrete structures, but the statistical distribution according to the wave type has not been studied clearly in view of data reliability and validity. Therefore, this study analyzed the statistical distribution of P-, S-, R-wave velocities in concrete wide beams of $800{\times}3100mm$ (width ${\times}$ length) with a thickness of 300 mm. In addition, we investigated an experimental consistency by the Kolmogorov-Smirnov goodness-of-fit test. The experimental data showed that the R-, S- and P- wave velocities in order have better statistical stability and reliability for in situ evaluation because R- and S-waves are less sensitive to confinement and boundary conditions. Also, good correlations between wave velocities and strength and modulus of elasticity were found, which indicate them as appropriate techniques for estimating the mechanical properties.

Purpose : This study is descriptive correlation research to provide basic materials for developing program which can give practical assistance in preventing and managing obesity through more comprehensive approaches of influential factors on obesity found in existing literatures. Methods : Data were collected from the 4th, 5th and 6th graders at 2 elementary schools in Gwangju Metropolitan City and 4 elementary schools in Jeollanamdo province using questionnaire and students' physical examination results from June 15 to July 27, 2006 and data obtained from 1,866 students were used for analysis. Data collected were analyzed with technical statistics and correlation analysis using SPSS/PC(version 12.0). Results : 1. Obesity level of elementary school students was examined as follows; 33.2% had low weight, 44.3% normal, 10.8% overweight and 11.7% obese. 14.8% of boys and 8.6% of girls, 13.5% of the 4th graders, 12.1% of the 5th graders and 9.2% of the 6th graders, and 13.7% of urban students and 9.6% of rural students were obese. 2. According to general characteristics and obesity of the subjects, there were significant differences by sex(${\chi}^2=29.55$, p= .000), grade(${\chi}^2=12.84$, p= .046), region(${\chi}^2=41.96$, p= .000) and pocket money(${\chi}^2=33.43$, p= .001). 3. As genetic factors, all variables including sibling's obesity r= .128(p= .000), mother's obesity r= .098(p= .000) and father's obesity r= .081(p= .001) had influence on children's obesity. 4. Concerning environmental factors, there was positive correlation between eating habits r=- .052(p= .02) and school record r=- .048(p= .04) and there was negative correlation between internet using time r= .050(p= .03) and conflict with parents r= .048(p= .04). 5. Self-respect as psychological factor had negative correlation as r=- .048(p= .04). Conclusion : Consequently, the influential factors on obesity of elementary school students were as follows. Obesity was higher in boys than in girls, in urban areas than in rural areas, in lower grade than in higher grade, in children with obese siblings, obese father and mother, irregular and wrong eating habits, frequent internet uses, parents in conflict and lower school record and self-respect. Therefore, since it was found that these variables were more exact causes to increase children's obesity, development of various obesity mediation programs considering these variables at home, school and society is urgently required.

In this paper, our main purpose is to establish the existence of weak solutions of a weak solutions of a class of p-q-Laplacian system involving concave-convex nonlinearities: $$\{\array{-{\Delta}_pu-{\Delta}_qu={\lambda}V(x)|u|^{r-2}u+\frac{2{\alpha}}{\alpha+\beta}|u|^{\alpha-2}u|v|^{\beta},\;x{\in}{\Omega}\\-{\Delta}p^v-{\Delta}q^v={\theta}V(x)|v|^{r-2}v+\frac{2\beta}{\alpha+\beta}|u|^{\alpha}|v|^{\beta-2}v,\;x{\in}{\Omega}\\u=v=0,\;x{\in}{\partial}{\Omega}}$$ where ${\Omega}$ is a bounded domain in $R^N$, ${\lambda}$, ${\theta}$ > 0, and 1 < ${\alpha}$, ${\beta}$, ${\alpha}+{\beta}=p^*=\frac{N_p}{N_{-p}}$ is the critical Sobolev exponent, ${\Delta}_su=div(|{\nabla}u|^{s-2}{\nabla}u)$ is the s-Laplacian of u. when 1 < r < q < p < N, we prove that there exist infinitely many weak solutions. We also obtain some results for the case 1 < q < p < r < $p^*$. The existence results of solutions are obtained by variational methods.

Dental caries are one of the most common oral diseases and Streptococcus mutans (S. mutans) plays an important role in the initiation and progression of dental caries. Oral malodor is primarily the result of microbial metabolism such as Porphyromonas gingivalis (P. gingivalis) that produce volatile sulfur compounds (VSCs), causing oral malodor. Prevotella intermedia (P. intermedia) is known as typical periodontopathic bacteria, and periodontal disease is chronic inflammatory disease that leads to damage of gingival connective tissue and alveolar bone, eventually loss of teeth. In this study, we investigated antimicrobial effect of mouthwash containing cetylpyridinium chloride (CPC), sodium fluoride (NaF), green tea water extract and pine needles water extract against cariogenic and periodontopathic bacteria sucn as S. mutans, P. gingivalis and P. intermedia. As a result, the reduction ratios of S. mutans and P. gingivalis were 4.00 Log and 4.68 Log reduction for 30 s, and P. intermedia were 2.40 Log reduction for 30 s and 2.70 Log reduction for 60 s. Dentocult SM Strip mutans (SM Strip) provides easy detection of visual data showing a significant inhibition on S. mutans. In conclusion, we expected that mouthwash containing CPC, NaF, green tea water extract and pine needles water extract could help preventing the dental disease like dental caries and oral malodor.

The law of territorial sea is a fundamental law by which the width of sovereign domain of a coastal state is determined. The P.R.China'a regime on the territorial sea was established through the Declaration on China's Ttrritorial Sea of 1958 and the P.R.China's Territorial Sea and Contiguous Zone Law of 1992. And the P.R.China's consistent policy on the territorial sea can be summarized as follows ; \circled1 The adoption of the straight baseline and 12 nautical miles of the territorial sea width, \circled2 The foreign merchant vessels can enjoy the right of innocent passage, while requesting for prior permission for the foreign military vessels on the entry into territorial sea. \circled3 The Chiungchow Strait and the Bohai Bay are claimed as the internal waters. \circled4 Enlistment of the whole coastal islands including the Taiwan. 12 nautical miles of the territorial sea width can be recognized as lawfull with respect to the 1982 UNLOS Convention. But the P.R.China's Territorial Sea and Contiguous Zone Law of 1992 contains some problems on the legality viewed in the light of customary international law. Firstly, it can be said that the adoption of simple straight baseline is not reasonable, and it must be investigated closely on the hidden intention of China. Secondly, there involved some possibility of international dispute on making Tung Tao which is 69 nautical miles apart from the mainland of a basepoint and on making the Bohai Bay of a historic bay. And also public notification of all basepoints for the straight baselines is necessary to meet the requirement of customary international law, Thirdly, two military zones established unilaterally in 1950 are illegal with respect to the customary international law, and they must be repealed deservedly. Fourthly, there have a lot of restrictions on the innocent passage even for foreign merchant vessels by the municipal law such as the Maritime Traffic Safety Law. As a conclusion, the P.R.China's territorial sea regime contains some illegal elements such as unilateral expansion of the maritime sovereignty or jurisdiction. In order to meet the general principle of the international law, the P.R.China's territorial sea policy must be modified on the basis of multilateral agreement with the states concerned. And Korea, as a state with opposite, has a definite right to take countermeasure agaist the P.R.China's contiguous zone.

Analysis of phylogenetic relationship was performed among Phellinus species based on 18S ribosomal subunit sequence data. Twenty-five strains of 19 Phellinus species including P. linteus were examined in this study. Regions of 18S ribosomal subunit were very conserved, but some variable regions between Phellinus species were observed. The species-specific detection primers, modified by 2 or 3 nucleotides in sense primer were designed based on 18S ribosomal DNA(rDNA) sequence data. The 210 by PCR bands were detected with annealing temperature $48^{\circ}C$. The 18S 2F-18S 4R detection primer set distinguished P. linteus from various Phellinus species but some species like P. baumii, P. weirianius, P. rhabarberinus and P. pomaceus also had weak reactivity on this primer set. The 18S 3F-18S 4R primer set distinguished only P. linteus from various Phellinus species, although sensitivity with this primer set was lower than that of 18S 2F-18 4R primer set. These primer sets would be useful for the detection of only P. linteus among unknown Phellinus species rapidly.
