Purpose: Early morning delivery markets have grown exponentially in the last few years. This study aims to verify the effects of brand experience factors and brand personality factors of Market Kurly, a representative early morning delivery brand, on brand attachment and brand loyalty. Research design, data, and methodology: For this purpose, 204 ordinary people in their 20s and 40s who have experience in using Market Kurly were surveyed. 7 hypotheses were verified by using hierarchical regression analysis. Results: Affective experience, intellectual experience, and behavioral experience among brand experience factors had a positive effect on brand attachment. Also, brand personality-self-image congruence and brand personality-human brand congruence as brand personality factors had a positive effect on brand attachment. The brand attachment was identified as an important preceding factor to explain the brand loyalty of Market Kurly. Conclusions: When applying brand experience factors to the early morning delivery service context, each brand experience factor affected brand attachment and brand loyalty. The scope of research on brand personality-self-image congruence was expanded in that it considered both brand personality-human brand congruence and brand personality-self-image congruence. This study provides academic and practical implications by revealing that brand experience factors and brand personality factors can positively affect brand attachment and brand loyalty.

A study was undertaken to investigate the effect of feeding early weaning diets based on different vegetable protein sources fed to Afghani lambs. Three isonitrogenous and isocaloric complete formula diets viz., A, B and C were prepared having cottonseed meal, soybean meal and canola meal; respectively as major source of protein. Eighteen 30-35 days old Afghani male lambs were randomly allotted to three experimental diets. Lambs were fed individually twice a day for a period of 60 days. Daily feed intake and weekly weight gain was recorded. Results indicated that weight gain was significantly(p<0.05) higher(282 g/lamb/day) in lambs fed diet B as compared to lamvs fed on diets A(231 g/lamb/day) and C(242 g/lamb/day). No significant difference was found in feed intake among the diets. Significant difference(p<0.05) were noticed in feed efficiency in lambs fed on diets A(6.88), B(5.41) and C(6.17).The economic efficiency was observed to be the best on diet B as compared to diets A and C. It was concluded that Afghani lambs(30-35 days) can be reared on early weaning diets and soybean meal was found comparatively better protein source for early weaning diet.

The purpose of this study was to investigate the relationships among control parenting, early adolescents' ego-resiliency and peer attachment. The subjects were 2,346 1st-year middle school students from all over the country. Korean Children and Youth Panel Survey(2010) data were analyzed by means of Pearson's correlation, hierarchical regression, and by the use of SPSS 19.0. The results of our study are as follows. First, parents' control parenting operated as a major determining factor with the effect that peer attachment decreased as parents' control parenting levels increased. Second, early adolescents' ego-resiliency operated as a major determining factor with the effect that peer attachment increased as adolescents' ego-resiliency levels increased. Finally, the interaction effects of parents' control parenting and early adolescents' ego-resiliency on peer attachment were observed.

All the plants on earth live under an electric and magnetic field because the earth is a magnet and there is an electric field between the charged cloud and the ground. It has been reported that electromagnetic fields influence both the activation of ions and polarization of dipoles in living cells of seeds and plants, though the mechanism of these actions is still poorly understood. In this paper, the effects of the electric and magnetic fields and exposure times to the germination of several vegetable seeds and its early growth have been investigated experimentally to find out the feasibility of a plant factory for mass production of clean and unpolluted vegetables. The germination rate and the growth rate of some seeds under the fields exposed were analysed and compared with those of unexposed ones. It is found that the germination rate and its early growth rate of exposed seeds under the fields were accelerated about 1.1-1.4 and 1.7-2.2 times in maximum compared with those of unexposed ones. But, however, an inhibitory effect on germination and plant early growth were shown in the case of the higher electric and magnetic fields.

Purpose: This study aimed to determine the effect of curved walking training on balance confidence and fall efficacy in early stroke patients. Methods: The study included 16 early stroke patients who were randomly allocated to a curved walking training group (experimental group, N=8) and a straight walking training group (control group, N=8). Both groups performed the exercise 5 times a week for 3 weeks. Outcomes were assessed using the Activities-specific Balance Confidence (ABC) Scale, Fall Efficacy Scale (FES), Berg Balance Scale (BBS), and Timed Up and Go (TUG) test. Results: After 3 weeks of training, both groups showed significantly improved ABC, FES, BBS, and TUG (p<.05 in both groups). However, the ABC, FES, BBS, and TUG scores in the experimental group were significantly better than those in the control group (p<.05). Conclusion: These findings indicate that curved walking training may be effective at improving balance confidence and decreasing fall risk in early stroke patients. Therefore, curved walking training can be used as a recommended walking method in early stroke patients.

Purpose This study analyzed the topic of game review contents and how the characteristics of game reviews affect the reviews helpfulness. In addition, this study explore the content of game reviews according to the game's sales strategy such as early access strategy and releasing without early access. Design/methodology/approach We collected a list of 3,572 action genre games released in 2020. 58,336 online reviews were collected by random sampling 50 reviews in each games, and topic modeling was performed on those reviews. We dynamized the results of topic modeling and analyzed the effect on review helpfulness with multiple regression analysis. Findings The results of analysis indicate that the longer the review is or the shorter the time it is written, the more helpful the review is. In addition the topic with positive and negative review has a significant effect on the review helpfulness. As a result of exploratory analysis, games from early access had relatively fewer reviews of story-related topics than games that were released without early access. These findings can present direct guidelines for collecting specific opinions from customers in the game industry when releasing games.

Objectives : The aim of this study was to investigate the relationship between depressive symptom, spiritual well-being and state hope in early adults and middle aged patients with depression. Methods : A total of 180 outpatient were surveyed with Beck Depression Inventory (BDI), Functional Assessment of Chronic Illness Therapy-Spiritual Well-being Scale (FACIT-Sp) and The State Hope Scale (SHS). Mean scores of BDI, FACIT-Sp and SHS were compared between two groups of different age. Correlation analysis and multiple linear regression analyses were performed to identify the effect of BDI and FACIT on SHS according to age. Results : Mean scores of SHS and FACIT were higher significantly in middle aged group than early adults group, while BDI was not different between two groups. And early adults and middle aged patient's state hope showed a significantly negative correlation with spiritual well-being. In regression analysis, the effect of BDI, FACIT on SHS were significant in both groups and the regression model explained 42% of the variance of state hope in early adults group and 26% in middle aged group, respectively. Conclusion : These findings suggest that in depressive symptom and low state hope relationship, spirituality is important protective factor in both aged adult outpatients with depression.
