To determine the optimal media conditions for the detection of the extracellular cellulase activity in Ganoderma neo-japonicum, we varied three media conditions: dye reagent, pH, and temperature. We evaluated the use of four dyes, Congo red, phenol red, remazol brilliant blue, and trypan blue. To observe the effect of pH on the chromogenic reaction, we tested media ranging from 4.5 to 8.0. To research the effect of temperature on the clear zone and the fungus growing zone, we tested temperatures ranging from 15 to $35^{\circ}C$. On the whole, the best protocol called for Ganoderma neo-japonicum transfer onto media containing Congo red with a pH of 7.0, followed by incubation at $25^{\circ}C$ for 5 days. Our results will be useful to researchers who study extracellular enzyme activity in Ganoderma neo-japonicum.

Corporate social media has been recently used in customer relationship management in many ways to improve product sales and company images. Not much research exists on corporate social media, Therefore, in this paper, we propose a research model to identify how corporate social media enhances corporate's CRM quality, resulting in forming customer's purchase intention. In detail, this paper is to examine how customer's perceived value of corporate social media influences CRM quality(CRM trust and CRM commitment), and then how CRM quality affects purchase intention. To this end, a total of 300 questionnaires were used from online panel respondents to test research hypothesis. The findings showed that service performance value and monetary value were major determinants of CRM trust, however, there was no association between brand integration value and CRM trust. In addition, the effects of service performance value and brand integration value on CRM commitment were found whereas monetary value had no effect on CRM commitment. The results also showed that CRM trust and CRM commitment played a critical role in forming of purchase intention. Theoretical and practical Implications are discussed.

Objective: This study aimed to examine the mediating effect of mothers' parenting stress on the relationship between their self-differentiation and the tendency of addiction to social media. Methods: The participants in this study were two hundred and eight mothers with children aged 36 months or younger. Data were analyzed statistically using frequency, Pearson's correlation coefficients, and hierarchical multiple regression analysis. Results: The results of the present study are as follows. First, the mothers' self-differentiation was negatively associated with their parenting stress and social media addiction tendency. Second, both the total scores of the mothers' parenting stress and their distress were found to partially mediate the relationship between their self-differentiation and social media addiction tendency. However, the mothers' daily stress did not mediate the relationship between the variables. Conclusion/Implications: The findings of the current study have implications for developing ways of intervening in mothers' social media addiction tendency by reducing their parenting stress, particularly for mothers with low levels of self-differentiation.

The goal of this research is to look into the relationship between social media marketing activities and brand attachment in the online marketing business, based on the indirect effect of perceived value and self-brand connections. For this reason, the study has used self-administered questionnaires to collect the data from 425 males from the major cities of Pakistan including Islamabad, Karachi, Lahore, and Sialkot. Furthermore, based on the PLS-SEM technique the empirical findings show that social media marketing activities positively affect perceived value, self-brand connections, and brand attachment. Perceived value has a significant positive impact on brand attachment and mediates the influence of social media marketing activities on brand attachment. In addition to this, self-brand connections have a positive effect on brand attachment, and self-brand connections mediate the relationship between them. Thus, firms employing social media marketing activities successfully in their branding build upon a positive perception of the brand in the customer's mind resulting in customer attachment with the brand. This study can assist the e-commerce managers and brand managers in building strong customer attachment via perceived value and self-brand connections.

Purpose: The popularity of social media has altered how customers interact with businesses, and an increasing number of customers prefer to voice their complaints on social media. Bystanders can observe the customer complaint process on social media, but the impact of transparency on bystanders remains uncertain. Therefore, this study established and verified a model for defining the effect of transparency and service recovery types on bystanders. Research Design and Methodology: In this study, we used the internet survey platform "So Jump" to collect data. And we validated three studies with SPSS 26.0 and Smart PLS 4.0. Result: First, we showed that the transparency process (vs. result) is more likely to increase customer forgiveness and E-loyalty and reduce E-NWOM intention among bystanders. Second, customer forgiveness also plays a complementary mediating role between transparency and E-loyalty, as well as between transparency and E-NWOM intention. Finally, we found a modest interaction effect between transparency (process vs. result) and service recovery types (psychological vs. tangible vs. hybrid) on bystanders' customer forgiveness and E-loyalty. Conclusions: This study provides actionable recommendations for how service managers can effectively employ social media as a means for distributing feedback information to manage service recovery in the future.

본 연구의 목적은 전신 PET/CT영상에서 조영제의 영향에 대한 보정 유 무가 SUV (standard uptake value)에 미치는 영향을 평가하는 것이었다. 영상획득은 GE DSTe PET/CT 시스템을 사용하였으며, 간질환(hepatocellular carcinoma, HCC)과 신장질환(renal cell carcinoma, RCC)이 있는 환자를 대상으로 하여 영상을 평가하였다. 영상 평가는 조영제에 의한 영향을 보정한 영상과 보정하지 않은 영상에서 각각 동일한 위치에 같은 크기의 관심영역을 설정한 후 각 관심영역으로부터 구한 SUV를 비교함으로써 수행하였다. HCC 환자의 경우 조영제에 의한 영향의 보정 유 무에 따른 평균 SUV의 차이는 $1.5{\pm}1.2%$이었고, 최대 4.3%의 SUV 차이를 나타내었다. RCC 환자의 경우 평균 SUV의 차이는 $1.0{\pm}0.9%$이었고, 최대 1.9%의 SUV 차이를 나타내었다. 조영제를 사용한 PET/CT 영상에서 조영제에 의한 영향을 보정하지 않았을 경우는 조영제에 의한 영향을 보정해준 경우에 비해 상대적으로 높은 SUV를 나타내었다. 본 연구의 결과는 HCC 환자와 RCC 환자의 경우 조영제에 의한 영향을 보정한 경우와 보정하지 않은 경우 SUV에 큰 차이를 보이지는 않았으나, 향후 보다 많은 수의 HCC 환자와 RCC 환자를 대상으로 한 추가적인 연구가 필요할 것이라고 생각한다. 또한 다른 질환을 가진 환자의 경우에 대해서도 조영제가 SUV에 미치는 영향을 평가하는 것은 매우 유용하리라 생각한다.
