This descriptive research study investigates nursing Workplace spirituality, grateful disposition, hope, and nursing performance of clinical nurses to identify related factors. The study participants were 323 nurse working general hospitals K, P, and S cities. Data were collected during July and August 2022 using a structured questionnaire. The SPSS 25.0 program was used to analyze descriptive statistic, t-test, ANOVA, Pearson correlation coefficient, and hierarchical regression analysis. The study results indicated that nursing performance was 4.23 out of 7, nursing workplace spirituality was 4.48 out of 7, grateful disposition was 4.23 out of 7, and hope was 2.77 out of 4. Result showed that nursing performance is positive associated nursing workplace spirituality (r=.58, p<.001), grateful disposition (r=.41, p<.001), and hope (r=.47, p<.001). The result of hierarchical regression analysis that grateful disposition (β=.417, p<.001), hope (β=.357, p<.001), and nursing workplace spirituality (β=.235, p<.001), were predictive of nursing performance (R²=.301, p<.000). Therefore, educational programs and workforce management systems that can enhance nursing workplace spirituality, grateful disposition, and hope in the workplace are needed to improve nursing performance.

The relationships among long-term climatic change in the southern part of the Korean peninsula, oceanic conditions of the South Sea, Korea, and winter catches of major small pelagic fishes were analyzed using 33 years of time-series data from 1971-2003. In the early 1990s, winter climatic conditions in the southern part of the Korean peninsula shifted to a warmer regime with higher air temperature, weaker wind speed, and lower relative humidity. Also, winter sea surface temperature (SST) became consistently higher in the South Sea. The annual catch of major small pelagic fishes in the South Sea increased dramatically in the mid 1990s, whereas the catch of total fishes decreased in the late 1980s. In particular, the winter catch started to increase markedly in the late 1980s, and has remained over 120,000 M/T since the late 1990s. Correlation analysis of the winter catch of major small pelagic fishes and environmental factors showed that catch was correlated with air temperature (r=0.468, P< 0.01), wind speed (r=-0.732, P< 0.01), relative humidity (r=-0.73l, P< 0.01), and SST (r=0.672, P< 0.01). Multiple regression analysis between the winter catch of major small pelagic fishes (Y) and environmental factors (X) resulted in the equation: $Y=-0.017-0.217\;X_3-0.486\;X_4+0.325\;X_5(R^2=0.754,\;P<0.000)$.

Purpose: This study investigated the effects of menopausal adaptation and Sanhujori (Korean traditional postnatal care) on the Health-related quality of life in middle-aged women. Methods: Women aged from 45 to 60 completed questionnaires consisting of SF-36 ver. 2 and menopausal adaptation scale between July to Aug, 2013. Two hundred and eighteen participants' data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient and multiple regression. Results: Physical health ($69.5{\pm}15.1$) was better than mental health ($68.8{\pm}17.1$), and bodily pain and social functioning were the same results as 2009 general U.S. population, with the sub-variables of quality of life being lower. Menopausal adaptation was at moderate level, and correlation of its sub-variables with quality of life were significant: fatigue (r=.60, p<.001), accomplishing feeling (r=.55, p<.001), confidence (r=.54, p<.001), dryness (r=.51, p<.001), flush (r=.38, p<.001), dominance (r=-.36, p<.001), stability (r=.26, p<.001). Fatigue, confidence, stability, period of sanhujori, and dryness revealed as influencing quality of life, while the total variation explained by these components was at 52%. Conclusion: To improve quality of life of middle aged women, health care providers need to provide nursing intervention to relieve fatigue and dryness; and address psychosocial concerns with developing nursing strategies to improve stability and confidence. For post-partum women, enough periods of sanhujori needs to be recommended.

This study was performed to develop a natural preservative which had the most successful effect on prolonging the vase life of cut flowers Rosa hybrida 'Enjoy'. To determine the effect of sucrose on vase life of cut roses, R. hybrida 'Enjoy', 0, 1, 3 or 5% of sucrose was mixed with Hypnum jutlandicum extract. The result showed that in the case of adding sucrose to extracts from H. jutlandicum, vase life of cut flowers was shortened, along with the cut flowers losing chlorophyll, becoming decolorized and finally showing wilting phenomenon. However, using hydroxy quinoline sulfate (HQS) and extracts from H. jutlandicum together exhibited an improved effect of prolonging vase life, especially when adding 100 $mg{\cdot}L^{-1}$ HQS, which had the effect of prolonging the vase life of R. hybrida 'Enjoy' the most. Regarding pH of extracts, 2 $mg{\cdot}L^{-1}$ of extracts from H. jutlandicum show originally pH 3.8. This was compared with adjusted extract solutions as pH 3.0, 4.0 or 5.0. The results showed that the solution of pH 3.8 had the most successful effect on prolonging the vase life of R. hybrida 'Enjoy'. Given all the results, H. jutlandicum extract (2 $mg{\cdot}L^{-1}$) and HQS (100 $mg{\cdot}L^{-1}$) was the most effective in prolonging the vase life of cut R. hybrida 'Enjoy'. Moss is expected to be worth developing as a natural preservative since it is easy to get and causes no damage to the environment.

The purpose of this study was two-fold. First was to evaluate whether the molecular sieving model was appropriate for ionic dissociation experiment. Second was to compare the dissociation of calcium and hydroxyl ions from five types of calcium hydroxide pastes (Pure calcium hydroxide paste, DT temporary $dressing^{\circledR},{\;}Metapaste^{\circledR},{\;}Chidopex^{\circledR},{\;}Metapex^{\circledR}$) in three vehicles (aqueous, viscous and oily) and the antibacterial effect. Each calcium hydroxide pastes was placed into 0.65ml tube with cap and then 15% polyacrylamide gel was placed onto calcium hydroxide pastes. After the gel was hardened, the tubes were filled with tridistilled water (pH 7.14) and closed with cap. The tubes were stored in $37^{\circ}C$ 100% incubator The pH reading and the concentration of calcium ions were taken at 1, 4, 7. 10, and 14 days. The brain heart infusion agar plates with S. mutans and A. actinomycetemcomitans were used far antibacterial activity test. Middle of agar plate was filled with the calcium hydroxide pastes. The plates were incubated at $37^{\circ}C$ and observations were made to detect the zones of inhibition. These data were evaluated statistically by use of the analysis of variance and duncan test. The results were as follows. 1. In fresh mixing state, the pH of five types of calcium hydroxide pastes were measured between 12.5 and 12.8. 2. The pH was increased in all five types of calcium hydroxide pastes compared with control group. In 14 days, Pure calcium hydroxide paste (11.45) and DT temporary $dressing^{\circledR}$ (11.33) showed highest pH, followed by $Metapaste^{\circledR}$ (9.49), $Chidopex^{\circledR}$ (8.37) and $Metapex^{\circledR}$ (7.59) 3. Calcium was higher in all five types of calcium hydroxide pastes compared with control group. In 14 days, Pure calcium hydroxide paste (137.29 mg%) and DT temporary $dressing^{\circledR}$ (124.6 mg%) showed highest value, followed by $Metapaste^{\circledR}$ (116.74 mg%), $Chidopex^{\circledR}$ (111.84 mg%) and $Metapex^{\circledR}$ (60.22 mg%). 4. The zones of bacterial inhibition were seen around all five types of calcium hydroxide pastes. $Chidopex^{\circledR}{\;}and{\;}Metapex^{\circledR}$ groups which include iodoform were observed significantly larger zone of inhibition in A. actinomycetemcomitans compared with the other calcium hydroxide groups (p<0.05) However, $Metapex^{\circledR}$ showed the least antibacterial effect on S. mutans compared with other groups (p<0.05). The molecular sieving model was found to be acceptable in dissociation experiment of hydroxyl and calcium ions when compared with the previous tooth model study. But this model was not appropriate for the antibacterial test.

Neuroinflammation is defined as a neurological inflammation within the brain and the spinal cord. In neuroinflammation, microglia are the tissue-resident macrophages of the central nervous system, which act as the first line of defense against harmful pathogens. Dexmedetomidine (Dex) has an anti-inflammatory effect in many neurological conditions. Additionally, the microRNA-30a-5p (miR-30a-5p) mimic has been proven to be effective in macrophages in inflammatory conditions. This study aimed to investigate the synergistic anti-inflammatory effects of both miR-30a-5p and Dex in lipopolysaccharide (LPS)-induced BV2 cells. This study showed that miR-30a-5p and Dex decreased nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) translocation in LPS-induced BV2 cells. MiR-30a-5p and Dex alleviated tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6), LPS-induced phosphorylation c-Jun N-terminal kinases (JNK), extracellular signal-regulated kinase (ERK) and p38. Also, the expression of the NOD-like receptor pyrin domain containing 3 inflammasome (NLRP3), cleaved caspase-1, and ASC was inhibited. Furthermore, LPS-stimulated nitric oxide (NO) production, inducible nitric oxide synthase (iNOS), and cyclooxygenase-2 (COX-2) expression were attenuated by Dex and miR-30a-5p. Our results indicate that a combination of Dex and miR-30a-5p, attenuates NF-κB activation, the mitogen-activated protein kinase (MAPK) signaling pathway, and inflammatory mediators involved in LPS-induced inflammation and inhibits the activation of the NLRP3 inflammasome in LPS-activated BV2 cells.

The purposes of the study were to develop an instrument for family value and to identify the relationships of family value, family hardiness, and family adaptation by appling the family value scale to family with cancer children. The study was conducted in three phases. 1) A survey was conducted from July 20 to August 20, 1999 and 18 items of general family value scale was modified from the data of 153 fathers and 164 mothers. 2) In-depth interviews were made with 29 parents of cancer children from April 20, 1998 to May 20, 1999 to develop family value scale with cancer children, and 12 statements were developed. 3) The final survey was conducted from July 18, 2000 to August 30, 2000 and the data from 309 parents of children who are diagnosed as cancer, 18 or less years of age, and treated either hospitalized or at the outpatient clinics were analyzed to identify the relationships of the concepts. The data analysis utilized SAS 6.12 and LISREL 8 for descriptive statistics, correlation, and Regression for path analysis. The study findings are as follows. The psychometric testing of general family value scale was Cronbach's alpha = 0.78. The reliability of the family value scale with cancer children showed the reliability as Cronbach's alpha = 0.73. Demographic characteristics showing significant correlations were cancer children's age, period of illness, period after completing treatment, mother's age, mother's education level, monthly income, payment type, confidence with health professional, and severity of children's illness. The correlation coefficients among major variables showed that family stressor was positively related with family strains(r=0.33, p<.001), and negatively related with family hardiness(r=-0.21, p<.001). Family strains was negatively related with family hardiness(r= -0.41, p<.001) and family adaptation(r=-0.46, p<.001). Correlations of family hardiness was positive with family value with cancer children(r=-0.31, p<.001), and negative with general family value(r=-0.16, p<.01). Family hardiness was positively related with family adaptation(r=0.35, p<.001). The causal relationship between study variables showed that family strains predicts general family value(γ=0.12, t=2.02), family value with cancer children predicts family hardiness(γ=0.31, t=6.30), family strains predicts family hardiness(γ=-0.40, t=-7.70), family value with cancer children predicts family adaptation(γ=-0.23, t=-4.11), and family hardiness predicts family adaptation(γ=0.43, t=7.78).

Let (R, m) be a 2-dimensional regular local ring with algebraically closed residue field R/m. Let K be the quotient field of R and v be a prime divisor of R, i.e., a valuation of K which is birationally dominating R and residually transcendental over R. Zariski showed that there are finitely many simple v-ideals $m=P_0\;{\supset}\;P_1\;{\supset}\;{\cdotS}\;{\supset}\;P_t=P$ and all the other v-ideals are uniquely factored into a product of those simple ones. It then was also shown by Lipman that the predecessor of the smallest simple v-ideal P is either simple (P is free) or the product of two simple v-ideals (P is satellite), that the sequence of v-ideals between the maximal ideal and the smallest simple v-ideal P is saturated, and that the v-value of the maximal ideal is the m-adic order of P. Let m = (x, y) and denote the v-value difference |v(x) - v(y)| by $n_v$. In this paper, if the m-adic order of P is 2, we show that $O(P_i)\;=\;1\;for\;1\;{\leq}\;i\; {\leq}\;{\lceil}\;{\frac{b+1}{2}}{\rceil}\;and\;O(P_i)\;=2\;for\;{\lceil}\;\frac{b+3}{2}\rceil\;{\leq}\;i\;\leq\;t,\;where\;b=n_v$. We also show that $n_w\;=\;n_v$ when w is the prime divisor associated to a simple v-ideal $Q\;{\supset}\;P$ of order 2 and that w(R) = v(R) as well.

In recent years, many analysts have been using Python and R to analyze data using efficient analysis and statistics. However, it is difficult to solve the requirement to express various analyzes in real time through the web system using only two languages. In addition, it is possible to confirm that the extracted P-Value is different from the value in R because there is no corresponding algorithm in Java or the corresponding source is not verified. Therefore, in this paper, we propose a method to apply analyst 's analysis algorithm contents directly to his system using R in other languages.
