The objective of this study was to identify factors affecting the positive and negative responses of undergraduate students to inferiority by using a group counseling program to manage the inferiority of undergraduate students majoring in health science. This study sampled 30 undergraduate students attending the health science department of S University and divided them into a treatment group and a control group. The treatment group received an inferiority management group counseling program twice a week 120 minutes each from November 20, 2018, to January 2, 2019 eight sessions in total. The inferiority response criterion was applied before-treatment, after-treatment, and follow-up to verify the effectiveness of the program. The analysis results showed that the inferiority management group counseling program significantly decreased the negative response of undergraduate students to inferiority and significantly increased the positive response to inferiority. These results suggest that the inferiority management counseling program can lower the negative attitude and enhance the positive attitude toward the inferiority, which is caused by comparing themselves with their peers.

This research aims to examine the cause-and-effect relationship between Organizational Justice and Organizational Commitment within ICT corporates for fire prevention, through Leader-Member Exchange(LMX) and Organizational Support. A survey was conducted to corporate employees from staff members to executives. A total of 316 responses were collected during two weeks from May 1st to 17th, 2019, and were analyzed in this research. The result of the theory on ICT fire prevention was as follows: First, Distributive Justice has significant influence on Organizational Support, while it does not on LMX. Second, Procedural Justice has significant influence on both Organizational Support and LMX. Third, while Interactional Justice does not have significant influence on Organizational Support, LMX showed significant influence. Fourth, Organizational Support has significant influence on Organizational Commitment. Fifth, LMX has significant influence on Organizational Commitment. This research is academically significant in that it applied the Justice Theory on ICT corporates for fire prevention from staff members to executives. It is considered so, since existing researches mainly address on the status of technologies and policies on how to link fire prevention and ICT, and not on fair compensation based on Organization Justice theory. Practical significance can be found in its suggestions to improving organizational culture from top-down to bottom-up, thus creating free and engaging atmosphere at work. It is therefore needed to conduct further researches that categorize executives by their traits, and examine factors influencing on organizational commitment within ICT corporates for fire prevention.

Purpose: This study was conducted to evaluate the effectiveness of autogenic training on stress responses through a systematic review and meta-analysis. Methods: A systematic search was conducted using eight core electronic databases (Embase, CENTRAL, Medline, CINAHL, PsycInfo, DBpia, KISS, and RISS). To estimate the effect size, a meta-analysis of the studies was performed using RevMan 5.3.5 program. Results: A total 21 studies out of 950 studies were included in the review, and 11 were included for meta-analysis. These studies showed that autogenic training decreased anxiety and depression, and increased the high frequency of heart rate variability. Calculations to understand the effect of autogenic training on anxiety, through a meta-analysis, observed a reduction effect of anxiety score by 1.37 points (n=85, SMD=-1.37: 95% CI -2.07 to -0.67), in the studies on short-term intervention targeting healthy adults. On the other hand, similar calculations to understand the effect of autogenic training on depression observed, a reduction effect on the depression score by 0.29 point (n=327, SMD=-0.29: 95% CI -0.50 to -0.07), in the studies on long term intervention targeting the patient group. Conclusion: Autogenic training is effective for adults' stress management, and nurses will be able to effectively perform autogenic training programs for workers' stress relief at the workplace.

BACKGROUND: Epigeic arthropods participate in ecological functions as predators, decomposers and herbivores. The purpose of this study was to investigate the responses of some dominant arthropods in rice fields to different forms of agricultural land management. METHODS AND RESULTS: The abundance of microarthropods was compared between rice fields and uplands in the non-growing season. Collembola, Oribatida and Mesostigmata were more abundant in the upland fields than in the paddy fields. The community composition and diversity of epigeic arthropods were compared between fallow and rice fields. The total abundance and species richness of spiders and ground beetles were not significantly different in the two types of agricultural fields. The abundance of Arctosa kwangreungensis was greater in fallow fields than in cultivated fields. The community structure of arthropods was compared between paddy fields with and without barley. The cropping system altered the community composition of spiders but not their biodiversity. Barley cultivation increased the abundance of ground beetles but decreased that of spiders. We suggest that this contrast was partly due to the availability of plants that provided shelter and food for ground beetles. CONCLUSION: These results show that soil use intensity and cropping system alter the community composition of epigeic spiders and ground beetles. This could result in ecosystem-level alterations with respect to the control of pests and weeds. Our results also suggest that biodiversity of ground-dwelling arthropods may not increase during short fallow periods.

Purpose: Although multi-directional reaching exercises are commonly used clinically, the effects of specific movement directions on the muscle systems of the lower extremities have not been explored. We therefore investigated lower extremity muscle activity during reaching exercises with different sagittal and horizontal plane movements. Methods: The surface electromyography responses of the bilateral rectus femoris, tibialis anterior, peroneus longus, and gastrocnemius muscles were measured during reaching exercises in three directions in the horizontal plane (neutral, $45^{\circ}$ horizontal shoulder adduction, and $45^{\circ}$ abduction) and three directions in the sagittal plane (neutral, $120^{\circ}$ flexion, and $60^{\circ}$ flexion). A total of 20 healthy, physically active participants completed six sets of reaching exercises. Two-way repeated ANOVA was performed: body side (ipsilateral and contralateral) was set as the intra-subject factor and direction of reach as the inter-subject factor. Results: Reaching at $45^{\circ}$ horizontal shoulder adduction significantly increased the activity of the contralateral rectus femoris and gastrocnemius muscles, while $45^{\circ}$ horizontal shoulder abduction activated the ipsilateral rectus femoris and gastrocnemius muscles. The rectus femoris activity was significantly higher with reaching at a $120^{\circ}$ shoulder flexion compared to the other conditions. The gastrocnemius activity decreased significantly as the shoulder elevation angle increased from $60^{\circ}$ to $120^{\circ}$. Conclusion: Our results suggest that multi-directional reaching stimulates the lower extremity muscles depending on the movement direction. The muscles acting on two different joints responded to the changes in reaching direction, whereas the muscles acting on one joint were not activated with changes in reaching direction.

Mobile shopping has spread rapidly in the consumer's daily life, and numerous fashion companies have now launched a mobile shopping application. By focusing on mobile social commerce apps, this study was to: (a) segment consumers based on loyalty and switching intentions, (b) to test differences in perceived service quality and switching barrier factors among segments, and (c) examine the effects of perceived service quality and switching barriers on loyalty intention. A total of 550 responses were obtained from mobile users in their 20s to 40s who purchased fashion products through a social commerce app in the last six months. Consumers were classified into four clusters: split-loyals, latent loyals, habitual loyals, and switchers. The split-loyal group showed the highest level of mean scores on perceived service quality and switching barrier factors; however, the switcher group showed the lowest mean scores. Of service qualities, app design had a significant effect on loyalty intentions in both split-loyal and latent loyal groups; the factors of ease of use and privacy had significant effects on loyalty intentions in switchers. Of switching barrier factors, virtual relationship had the most strongly effect on loyalty intention for the four segments.

Purpose: The purpose of this study is to find out how much influence nursing students' environmental consciousness and knowledge of medical waste have on their attitudes toward medical waste. Methods: The subjects were 211 nursing students recruited from 2 universities. Data were collected with a structured self-report questionnaire comprising measures of environmental consciousness, and knowledge of and attitude toward medical waste. Data analysis was conducted with the SPSS/WIN 25.0 program. Results: A total of 211 copies of the questionnaire were used for the final analysis, except for 9 untrusted responses out of 220 that included missing values. Those subjects' environmental consciousness who received environmental education in middle and high schools was higher (t=3.15, p=.002). The higher their grades, the better their knowledge of medical waste (F=3.40, p=.035). Those subjects' knowledge of medical waste who received medical waste education was relatively high (t=3.14, p=.002). Those subjects with clinical practice experience had more sensitive attitudes toward medical waste (t=2.06, p=.041). Those subjects' attitudes toward Medical waste who received medical waste education at the universities were relatively high (t=2.04, p=.043). The subjects' environmental consciousness was positively correlated with their attitudes toward medical waste (r=.44, p<.001). The most influential factor in their attitudes toward medical waste is their environmental attitudes and medical waste education. Conclusion: The higher the nursing students' environmental consciousness, the higher their attitudes toward medical waste. It is necessary to provide environment and medical waste education for nursing students in order to strengthen their environmental consciousness and attitude toward medical waste.

Background No head to head comparison is available between surgical lip lifting and upper lip filler injections to decide which technique yields the best results in patients. Despite the growing popularity of upper lip augmentation, its effect on societal perceptions of attractiveness, successfulness and overall health in woman is unknown. Methods Blinded casual observers viewed three versions of independent images of 15 unique patient lower faces for a total of 45 images. Observers rated the attractiveness, perceived success, and perceived overall health for each patient image. Facial perception questions were answered on a visual analog scale from 0 to 100, where higher scores corresponded to more positive responses. Results Two hundred and seventeen random observers with an average age of 47 years (standard deviation, 15.9) rated the images. The majority of observers were females (n=183, 84%) of white race (n=174, 80%) and had at least some college education (n=202, 93%). The marginal mean score for perceived attractiveness from the natural condition was 1.5 points (95% confidence interval [CI], 0.9-2.18) higher than perceived attractiveness from the simulated upper lip filler injection condition, and 2.6 points higher (95% CI, 1.95-3.24) than the simulated upper lip lift condition. There was a moderate to strong correlation between the scores of the same observer. Conclusions Simulated upper lip augmentation is amenable to social perception analysis. Scores of the same observer for attractiveness, successfulness, and overall health are strongly correlated. Overall, the natural condition had the highest scores in all categories, followed by simulated upper lip filler, and lastly simulated upper lip lift.

The self-efficacy of pre-service teachers has been reported as a major factor in the instruction of the curriculum. In particular, considering the importance of science learning instruction for underrepresented students from the viewpoint of science education for all, pre-service elementary teachers' self-efficacy about science instruction for underrepresented students will be an important factor of science education for these students. The purpose of this study is to investigate the self-efficacy of pre-service elementary teachers in science instruction for underrepresented students. To this end, the science teaching and learning self-efficacy test tool (Lee & Im, 2010) was revised in accordance with the context of science teaching for underrepresented students into a total of 24 items using 5 Likert scales. Through using the test tool consists of 3 dimensions as Learning Efficacy, Teaching Efficacy and Outcome Expectancy, 81 pre-service elementary teachers were surveyed and the reliability of test tool was verified through factor analysis and assessing construct validity by using the responses. As a result of the analysis, setting 5 as the standard perfect score, the average score of self-efficacy per dimension was shown as 3.29 in Learning Efficacy, 2.89 in Teaching Efficacy, and 3.39 in Outcome Expectancy. We confirmed the tendency and difference of self-efficacy of the research objects according to their background factors in which direct and indirect experience relating to the science education for the underrepresented students. Also, we verified that pre-service elementary teachers' interest in science subject matter, teaching science and their perception of the value of science learning had significant relations with self-efficacy on science teaching for underrepresented students.

Five experimental diets were formulated to evaluate the effects of dietary enzymatically hydrolyzed tuna by-product on growth, non-specific immune responses, and hematology of juvenile rainbow trout (Oncorhynchus mykiss). A basal diet with 50% of fishmeal was used as control (CON) and four other diets replaced 12.5% ($TBB_{12.5}$), 25% ($TBB_{25}$), 37.5% ($TBB_{37.5}$), and 50% ($TBB_{50}$) of fish meal in the CON diet. Juvenile rainbow trout ($4.87{\pm}0.05g$) were randomly distributed into 15 tanks (50 L) and fed 3-4% of wet body weight two times a day. At the end of 7 weeks of feeding trial, weight gain, specific growth rate, feed efficiency, and protein efficiency ratio of fish fed CON diet were significantly higher than those of fish fed $TB_{50}$ diet (P < 0.05). But there were no significant differences among fish fed CON, $TBB_{12.5}$, $TBB_{25}$, and $TBB_{37.5}$ diets (P > 0.05). There were no significant differences in GPT levels among fish fed CON, $TBB_{12.5}$, $TBB_{25}$, and $TBB_{37.5}$ diets. Also, there were no significant differences in lysozyme, superoxide dismutase, glucose, and total protein levels in all experimental diet (P > 0.05). The broken-line analysis indicated that the minimum dietary level of enzymatically hydrolyzed tuna by-product to replace fishmeal could be 29.7% in rainbow trout. These results indicated that the optimum level of dietary enzymatically hydrolyzed tuna by-product could replace greater than 29.7% but less than 37.5% of fishmeal in juvenile rainbow trout diet.
