Present study was performed to identify the effects of SNS WOM characteristics on attitude and purchase intention as perceived in restaurant participants and to confirm the moderating effect according to SNS receivers' characteristics on formulated model. Survey method was employed to consumers who are using SNS to find restaurant foods through convenience sampling method in Seoul area. A total of 250 surveys were distributed and 230 were used for analysis, after excluding missing and unusual data. The results from this study are as follows. First, vividness of SNS WOM characteristics had a greater effect on attitude of restaurant food than timeliness, but the consensus and neutrality of SNS WOM characteristics have no significant effect on attitude of restaurant food. Second, SNS receivers characteristics found to moderate the relationships between vividness and timeliness of SNS WOM characteristics and attitude. However, SNS receivers characteristics did not have a moderating role relationships between consensus and neutrality of SNS WOM characteristics and attitude. Third, attitude of restaurant food had a significant effect on purchase intention.

Wave load prediction at zero forward speed using finite depth Green function is a well-established method regularly used in the offshore and marine industry. The forward speed approximation in deep water condition, although with limitations, is also found to be quite useful for engineering applications. However, analysis of vessels with forward speed in finite water depth still requires efficient computing methods. In this paper, a method for analysis of wave induced forces and corresponding motion on freely floating three-dimensional bodies with low to moderate forward speed is presented. A finite depth Green function is developed and incorporated in a 3D frequency domain potential flow based tool to allow consideration of finite (or shallow) water depth conditions. First order forces and moments and mean second order forces and moments in six degree of freedom are obtained. The effect of hull flare angle in predicting added resistance is incorporated. This implementation provides the unique capability of predicting added resistance in finite water depth with flare angle effect using a Green function approach. The results are validated using a half immersed sphere and S-175 ship. Finally, the effect of finite depth on a tanker with forward speed is presented.

Two lactic acid bacteria (LAB) designated J02 and J13 were recovered from fermented vegetables based on their ability to suppress soft rot disease caused by Pectobacterium carotovorum subsp. carotovorum (Pcc) on radish. J02 and J13 were identified as Lactobacillus pentosus and Leuconostoc fallax, respectively. The ability of J02 and J13 to suppress plant diseases is highly dependent on chitosan. LAB alone has no effect and chitosan alone has only a moderate effect on disease reduction. However, J02 or J13 broth cultures plus chitosan display a strong inhibitory effect against plant pathogens and significantly reduces disease severity. LAB strains after being cultured in fish surimi (agricultural waste) and glycerol or sucrose-containing medium and mixed with chitosan, reduce three cruciferous vegetable diseases, including cabbage black spot caused by Alternaria brassicicola, black rot caused by Xanthomonas campestris pv. campestris, and soft rot caused by Pcc. Experimental trials reveal that multiple applications are more effective than a single application. In-vitro assays also reveal the J02/chitosan mixture is antagonistic against Colletotrichum higginsianum, Sclerotium rolfsii, and Fusarium oxysporum f. sp. rapae, indicating a broad-spectrum activity of LAB/chitosan. Overall, our results indicate that a synergistic combination of LAB and chitosan offers a promising approach to biocontrol.

Sickness absence is one of the most important indicators for worker's health and occupational safety and health performance. Sickness absence is primarily depended upon sickness but psycho-social factors in workplace may moderate sickness absence. Even though worker is falling into illness, sickness absence can be prevented by job satisfaction. In Korea it is very difficult to find research output about the association of sickness absence with job satisfaction. This study is planned to investigate the effect of job satisfaction on sickness absence. The third Korean Working Conditions Survey done by Occupational Safety and Health Research Institute in 2011 was used to analyze by logistic regression analysis. The result has shown that job satisfaction has statistically significant effect on sickness absence and simultaneously diminish the effect of symptoms experience on sickness absence. The effect of job satisfaction is greater in short term sickness absence than in long term sickness absence. This study has some limitation because of the cross sectional data of Korean Working Conditions Survey. In future, sophisticated statistical analysis may be done with modelling.

Purpose: This study examines the relationships among perceived stress, humor style, responding humor and depression among college students and the mediating effect of humor between perceived stress and depression. Method: During the period May 6-16, 2013, a convenience sample of 200 subjects was obtained from college K in city G. Data analysis was performed by Pearson's correlation coefficients and regression analysis. Results: The average BDI score was 7.7. There were 40 (20.0%), 16 (8.0%), 8 (4.0%), and 11 (9.0%) students with mild, moderate, and severe depression, respectively. The group with depressive symptoms constituted 3.5% of students. There was a significant positive correlation between negative stress perception and depression. Conversely, there was a significant negative correlation between adaptive humor style and negative stress perception. Ultimately, there were significant negative correlations between positive stress perception, adaptive humor style, maladaptive humor style, responding humor and depression. To test the mediating effect of adaptive humor style in the relationship between negative stress perception and depression, a Sobel test was performed and Z-score of 1.7736 (p=.076) obtained. Conclusion: Though the mediating effect of an adaptive humor style on the relationship between perceived stress and depression was not significant, considering the negative correlation with depression, strategies to increase an adaptive humor style and responding humor is recommended to prevent depression in college students.

The purpose of this study is to understand and verify the incentives as an important market environment and to help consumers use them effectively, and consequently to improve the consumer welfare. This study examined the representative incentive, the sales promotions which can effect on the consumer decision making process and current issues of them. For the purpose, a coffee specialty store was hypothesized and the subjects were 20∼30 years old, since the sales promotions can be more effective toward the younger consumers making their decisions low-involvement goods and services. The conclusions can be summarized as follows; Consumers understand the advantages and disadvantages of sales promotion very well, and use them rationally and usefully to maximize their satisfaction. the sales promotions act as incentives in the all steps of decision making processes. Generally, consumers prefer to get things at a good price, so in this survey, the discount coupons and the point accumulative membership had more effect than others. Consumers pointed out controversial issues of the sales promotions as follows: the sales promotions could bring about cost rising and unnecessary and/or impulse buying, and stir up speculative motivation. These are common serious problems in the sales promotions. The sales promotions are very useful tools in promoting sales but not fundamental in the long run. Marketers and manufacturers should keep it in mind that the best way to satisfy the consumers is to keep all things in good quality and moderate price.

Objectives: This study was conducted to analyze the mediating effect of self-identity on the relationship between aggression and school life adaptation of early adolescents. Methods: This study used the 5th-year data of the Korean Children & Youth Panel Survey (KCYPS) including 159 middle school 2nd students from single-parent families. The data was analyzed with open source statistics program R 3.5.0 to determine whether self-identity had a mediating effect on school life adaptation as an independent variable. Results: A moderate correlation was found among aggression, self-identity, and school life adaptation. As a result of the Sobel test, self-identity of early adolescents demonstrated a significant mediating effect on the relationship between aggression and school life adaptation. Conclusions: Given the significant mediating factor of self-identity, the strategies for early adolescents to boost their overall school life adaptation should be considered through intervention programs that help to enhance their self-identity.

Purpose: This study aimed to identify the mediating and moderating effects of mindset and psychological collectivism, respectively, on the relationship between grit and nursing intention for children with emerging infectious diseases, including coronavirus disease 2019 (COVID-19), among pediatric nurses. Methods: We conducted a cross-sectional descriptive study with 230 pediatric nurses. Results: Grit directly impacted mindset (β=.27, p<.001) and nursing intention (β=.20, p=.001). The direct effect of mindset on nursing intension (β=.28, p<.001) and the indirect effect of grit on nursing intension via mindset (β=.08, p<.001) were significant. Accordingly, mindset mediated the effect of grit on nursing intention. The effects of grit and psychological collectivism (β=.19, p=.003), respectively, on nursing intention were significant. However, the interaction between grit and psychological collectivism was not significant. Thus, psychological collectivism did not moderate the effect of grit on nursing intention. Conclusion: The findings demonstrate the importance of pediatric nurses' grit and mindset on their intended care for patients in critical situations. Cultivating a gritty culture and developing interventions to enhance nurses' personality traits associated with their performance will be crucial, and such measures are especially salient for pediatric nurses to face the new adjustments required in the era of COVID-19.

Purpose: This was integrative literature review for analyzing interventions of musculoskeletal symptom and pain on nurses. Methods: Data were searched by using databases, namely SAGE journals, EBSCOhost, PubMed, RISS, NDSL and KCI Search terminology included nurse and musculoskeletal and the language was Korean or Engli.sh. Data analysis was classified by risk of bias, inconsistency, indirectness and imprecision. Total six studies, one Korean and five English articles analyzed. Results: Risk of bias was serious in three of six studies. Regarding inconsistency, one study was moderate effect size and two studies were small effect size. There was no serious indirectness except one study. Regarding imprecision, three studies were not serious. Conclusion: Evidence from six studies was insufficient to support intervention's effect in means of no repeated studies and no high effect size of intervention. Evidence-based interventions must be applied on nurses for reducing musculoskeletal symptoms.

The study answers the awareness of taxpayers, tax authority services, tax socialization, tax collection, and account representative's controlling (monitoring) for compliance of the corporate Taxpayer. The study also examines the moderating effect of the tax audit to control the corporate Taxpayer's compliance. In this study, the method of non-probability sampling was used. The research data was gathered by handing out questionnaires at the Medan Kota Tax Office in Indonesia. The SEM method was used for data analysis through Lisrel 8.8 program. The findings of the study concluded that tax collection has a significant positive effect on corporate taxpayer's compliance and Tax audit moderates the relation between tax authority services and the account representative's controlling (monitoring) with corporate taxpayers' compliance. Also, tax socialization and account representative's controlling (monitoring) have a positive effect on the corporate taxpayer's compliance. In contrast, variables of taxpayer's awareness and tax authority services have a negative impact. Furthermore, tax audit does not moderate the relation between taxpayer awareness, tax socialization, and tax collection with the corporate taxpayer's compliance at Medan Kota Tax Office Indonesia. The findings suggest the Indonesian policymakers and tax authorities must create corporate legislation to handle compliance by leveraging the loopholes in tax legislation law and the tax audit system.
