Purpose: The purpose of this study is to identify protective factors associated with school adjustment of victims in school bullying. Methods: Data were collected from 114 victims among 825 middle school students. The measurements were the self-report questionnaire on resilience, and the Childrearing Behavior Questionnaire, measurements of relationship with friends, and attitude of teachers toward bullying. Descriptive, Pearson correlation, and multiple regression analyses were used. Results: A significant relationship was observed between school adjustment of victims and resilience (r=.355, p<.01), warmth-acceptance parenting behavior (r=.482, p<.01), rejection-restriction parenting behavior (r=-.213, p<.01), and teacher's attitude toward bullying (r=.381, p<.01). The result of multiple regression analysis showed significant association of school adjustment with resilience (${\beta}$=0.247, p<.05), warmth-acceptance parenting behavior (${\beta}$=0.302, p<.001), and teacher's attitude toward bullying (${\beta}$=0.285, p<.01). Conclusion: Comprehensive interventions designed to enhance the resilience of students, improve warmth-acceptance parenting behaviors and teacher's attitude toward bullying may be helpful in promoting school adjustment of victims.

Using the Lukasiewicz 3-valued implication operator, the notion of an (${\alpha},{\beta}$)-intuitionistic fuzzy left (right) $h$-ideal of a hemiring is introduced, where ${\alpha},{\beta}{\in}\{{\in},q,{\in}{\wedge}q,{\in}{\vee}q\}$. We define intuitionistic fuzzy left (right) $h$-ideal with thresholds ($s,t$) of a hemiring R and investigate their various properties. We characterize intuitionistic fuzzy left (right) $h$-ideal with thresholds ($s,t$) and (${\alpha},{\beta}$)-intuitionistic fuzzy left (right) $h$-ideal of a hemiring R by its level sets. We establish that an intuitionistic fuzzy set A of a hemiring R is a (${\in},{\in}$) (or (${\in},{\in}{\vee}q$) or (${\in}{\wedge}q,{\in}$)-intuitionistic fuzzy left (right) $h$-ideal of R if and only if A is an intuitionistic fuzzy left (right) $h$-ideal with thresholds (0, 1) (or (0, 0.5) or (0.5, 1)) of R respectively. It is also shown that A is a (${\in},{\in}$) (or (${\in},{\in}{\vee}q$) or (${\in}{\wedge}q,{\in}$))-intuitionistic fuzzy left (right) $h$-ideal if and only if for any $p{\in}$ (0, 1] (or $p{\in}$ (0, 0.5] or $p{\in}$ (0.5, 1] ), $A_p$ is a fuzzy left (right) $h$-ideal. Finally, we prove that an intuitionistic fuzzy set A of a hemiring R is an intuitionistic fuzzy left (right) $h$-ideal with thresholds ($s,t$) of R if and only if for any $p{\in}(s,t]$, the cut set $A_p$ is a fuzzy left (right) $h$-ideal of R.

Purpose: The purpose of this study was to investigate the reality of workplace violence experienced by emergency nurses and the relationship of violence response to professional quality of life. Methods: The participants in this study were 899 emergency nurses from Korea nationwide. Data were obtained through an online survey done during October, 2017. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficient. Results: Of the emergency nurses, 72.1% recognized that workplace violence is serious. Experience with workplace violence correlated positively with violence reaction (r=.32, p<.001), burnout (r-.20, p<.001) and secondary trauma (r=.22, p<.001). Also, reaction to violence was positively correlated with burnout (r=.28, p<.001) and secondary trauma (r=.56, p<.001). Conclusion: Findings indicate that the diverse workplace violence experienced by emergency nurses decreases their professional quality of life. Further study is needed to develop solutions to the problem of workplace violence in emergency settings.

To investigate the relationship between breathing pattern disorder and pain in patients with chronic low back pain(CLBP). One hundred four patients were measured the End-tidal CO₂(EtCO₂) and respiration rate(RR) using capnography. Also, The Breathing-hold time(BHT), Nijmegen Questionnaire(NQ), and Thoracic excursion examinated. There was a significant correlation between EtCO₂ and BHT, thoracic excursion(r=.302, r=.281)(p<.01), and a low negative correlation with RR, VAS(r=-.253, -200)(p<.05). There was a significant correlation between NQ and RR(r=.237)(p<.05). There was a low correlation between thoracic excursion and VAS(r=-.370)(p<.01). There was a significant difference in the EtCO₂, RR, BHT, thoracic excursion, and VAS between the thoracic and diaphragm breathing pattern(p<.05). There were no significant differences in the NQ(p>.05). There was a correlation between EtCO₂ and BHT, thoracic excursion, RR, VAS in patients with CLBP. In addition, There was a correlation between RR and NQ, thoracic excursion, and VAS. As a result, it was found that there is a close relationship between breathing pattern disorder and pain. There was a significant difference in the EtCO₂ level, RR, BHT, thoracic excursion and VAS value in the comparison of thoracic breathing pattern and diaphragm breathing pattern. This is a meaningful result of suggesting a breathing pattern treatment approach in the rehabilitation and pain management of chronic low back pain patients in clinical practice.

Recently, the high turnover rate of nursing staff and the problems caused by increased job stress have been highlighted as social issues, and the problem of 'Taeoom' in nursing organizations has received increasing attention. Therefore, the purpose of this study is to propose a solution to the Taeoom problem, including bullying in the nursing work environment, as there is an urgent need to find a solution to prevent and overcome this problem. For this purpose, based on the S-O-R framework and previous studies, job stress and turnover intention were derived as outcome variables of Taeoom and communication competence as an antecedent factor, and a research model was constructed with the expectation that mindfulness and social support would serve as moderating variables to help overcome this problem. Data were collected through a survey of 300 nurses who had experienced Taeoom within the past year, and the hypotheses were tested using a structural equation model. The results revealed that the higher the communication competence of nurses, the less they perceived the damage of Taeoom, and that the damage caused by Taeoom leads to turnover intention through high job stress. In addition, mindfulness and social support significantly attenuated the positive effects of burnout on job stress and job stress on turnover intention, respectively. The significance of this study is that it proposed an extended P-S-O-R framework by adding a prevention stage to the existing S-O-R framework, and further tested the moderating effects of mindfulness and social support variables. It is expected that the findings of this study will provide concrete guidelines to prevent and overcome the Taeoom problem that can be applied in practice.

Paratuberculosis (Johne's disease), a chronic enteritis produced by Mycobacterium paratuberculosis, affects a large proportion of ruminants in all continents and causes important economic losses. The identification of well-characterized and species-specific components of M paratuberculosis would provide the means to improve the specificity and sensitivity of immunodiagnostic assays for Johne's disease. The aims of this study were to express the recombinant C-terminal of 34kDa protein (rC34P) of M paratuberculosis in E coli and to investigate the effectiveness of this protein in detecting antibodies to the native protein in sera from paratuberculosis infected cattle. The C-terminal of the gene encoding the 34kDa protein was amplified by polymerase chain reaction from the chromosomal DNA of M paratuberculosis (ATCC 19698) and cloned into vector pGEX-4T-2. Then, cloned plasmid was transformed into E coli DH5${\alpha}$ and the rC34P was overexpressed. The rC34P was purified by affinity chromatography and gel filtration. The rC34P was examined antigenicity by Western blot. The rC34P was reactive with culture positive bovine serum and hyperimmune rabbit anti-M paratuberculosis serum but was not reactive with culture negative bovine serum and tuberculin positive bovine serum in Western blot. In conclusion, the rC34P produced in this study is expected as a useful candidate for antigen in serological diagnosis of Johne's disease.

We constructed four recombinant plasm ids to enhance the production of clavulanic acid (CA) in Streptomyces clavuligerus NRRL3585: (1) pIBRHL1, which includes ccaR, a pathway-specific regulatory gene involved in cephamycin C and CA biosynthesis; (2) pIBRHL2, containing claR, again a regulatory gene, which controls the late steps of CA biosynthesis; (3) pGIBR containing afsR-p, a global regulatory gene from Streptomyces peucetius; and (4) pKS, which harbors all of the genes (ccaR/ claR/ afsR-p). The plasmids were expressed in S. clavuligerus NRRL3585 along with the $ermE^*$ promoter. All of them enhanced the production of CA; 2.5-fold overproduction for pIBRHL1, 1.5-fold for pIBRHL2, 1.6-fold for pGIBR, and 1.5-fold for pKS compared to the wild type.

The aim was to determine the relationship between muscle structure and meat quality traits in neuromuscular compartments (NMCs: R1, R2, R3, R4) of pig semitendinosus muscle. Barrows from the INTA-MGC genetic line (Argentina) were slaughtered at 100 kg body weight. In each NMC the following parameters were determined: the fibre types I, IIA, IIX and IIB by immunohistochemistry, the fibre cross sectional area (FCSA), the pH of meat after 24 h post-mortem ($pH_{24}$), instrumental meat tenderness (WB) and colour ($L^*$, $a^*$, $b^*$). There were significant differences in the following: $L^*$ (R1 = R4$a^*$ (R1>R4>R2 = R3), $b^*$ (R1 = R4R1 = R3 = R4), $pH_{24}$ (R1 = R4>R2 = R3). The relative percentages of FCSA were as follows: I (R4>R1>R3>R2), IIA (R1>R4>R3>R2), IIX (R1 = R2 = R3 = R4) and IIB (R2>R3>R1>R4). The correlation values were statistically significant between IIB and WB (R1 and R4, $r_s$ = 0.66), (R2 and R3 $r_s$ = 0.74), IIB and $L^*$ (R1 and R4 $r_s$ = 0.84), IIX and $L^*$ without discriminating NMCs. Our data suggest that the NMC where the sampling takes place is important for determining meat quality traits because of the heterogeneity of the whole muscle.
