The relative extrinsic value orientation (REVO) means the relative importance to extrinsic values (e.g. wealth, fame and social approval) compared with intrinsic values (e.g. affiliation, self-acceptance and personal growth). This study aimed to investigate the causal relation between REVO and life-satisfaction using the auto-regressive cross-lagged modeling. For this purpose, 3rd, 5th, and 7th year data from the Korea Children and Youth Panel Survey (KCYPS) middle school 1st grade panel was analyzed (N = 2,259; 1,140 males and 1,119 females). The results are as follows; Firstly, positive auto-regressive effects of REVO and life-satisfaction were significant. Secondly, REVO was found to have negative and cross-lagged effect on life-satisfaction. However, cross-lagged effect from life-satisfaction to REVO was not significant. Finally, no gender difference was found in this relationship. These results suggest that low life satisfaction does not cause the relative extrinsic value orientation, but high relative extrinsic value orientation may cause low life satisfaction.

In concrete mix design we need the informations of the codes, the specifications, and the experiences of experts. However we can't consider all factors regarding concrete mix design. The final acceptance depends on concrete quality control test results. In this process we meet the uncertainties of materials. temperature, site environmental situations, personal skillfulness. and errors in calculations and testing process. Then the mix design adjustments must be made. Concrete mix design and adjustments arc somewhat complicated, time-consuming. and uncertain tasks. In this paper, as a tool to minimize the uncertainties and errors the neural network is applied to the concrete mix design. Input data to train and test the neural network are obtained numerically from the results of design following the concrete standard specifications of Korea. The 28-days compressive strengths which are variate according to the uncertainties and errors are considered. The results show that neural networks have a strong potential as a tool for concrete mix design.

This study is the research about the internet marketing strategy and the impact factors of psychological well-being of customers of restaurants. For the purpose of study, firstly, the paper was carried out in order to verify the cause and effect relationships of life satisfaction and psychological well-being of the customers in the food service industry. The customers of restaurants in Busan are the objectives for which the survey for empirical analysis was conducted. The result of the testing of hypothesis showed that life satisfaction will have positive influences on psychological well-being, it reveals that life satisfaction has positive influences on three factors of psychological well-being such as personal growth, self acceptance, independence. However, factor of autonomy is rejected. Secondly, the results of the study suggest the importance of introducing variegated internet marketing programs and deciding the appropriate information contents for the customer to activate the use of hands on restaurants. Internet information contents on customer satisfaction and customer loyalty to have a good understanding of the attitude will improve of life satisfaction and psychological well-being of the customers. Strategic information contents of internet marketing for customers of the restaurants must be consider "CRM(customer relationship management)".

Hardware-in-the-loop (HIL) simulation is a technique that can be employed for developing and testing complex real-time embedded systems. HIL simulation provides an effective platform for verifying power management system (PMS) performance of liquefied natural gas carriers, which are high value-added vessels such as offshore plants. However, HIL tests conducted by research institutes, including domestic shipyards, can be protracted. To address the said issue, this study proposes a field programmable gate array (FPGA) based PMS-HIL simulator that comprises a power supply, consumer, control console, and main switchboard. The proposed HIL simulation platform incorporated actual equipment data while conducting load sharing PMS tests. The proposed system was verified through symmetric, asymmetric, and fixed load sharing tests. The proposed system can thus potentially replace the standard factory acceptance tests. Furthermore, the proposed simulator can be helpful in developing additional systems for vessel automation and autonomous operation, including the development of energy management systems.

This study was conducted to investigate the quality characteristics of cookies added with different levels of flaxseed powder. Cookies were prepared with four different levels (0%, 6%, 12% and 18%) of flaxseed powder and the physicochemical properties were examined. The pH of cookie dough was higher in cookies containing flaxseed powder. The spread factor of control cookie was lower than that of cookies containing 6%, 12% and 18% of flaxseed powder. The incorporation of flaxseed powder in cookies lowered lightness and yellowness but increased redness values. Rheology testing showed that cookies with 6%, 12% and 18% flaxseed powder had significantly lower hardness value than control cookies (p < 0.05). Consumer acceptance test revealed that overall preference score was the highest in cookies containing 12% flaxseed powder. During storage at $55^{\circ}C$ for 60 days, peroxide value increased until 30 days of storage and decreased thereafter, while acid value steadily increased and there was no significant difference in peroxide value and acid value between control cookies and flaxseed added cookies.

This study explores the effect of anthropomorphism on fashion chatbot reliability, mediated by perceived intelligence and cognitive evaluation. The moderating effects of individuals' need for human interaction between chatbot anthropomorphism and perceived intelligence, cognitive evaluation, and chatbot reliability are also explored. Participants, who were recruited through the online research firm, responded to questions after watching a video clip showing a conversation with a fashion chatbot on a mobile screen. The data were collected through Mturk, a crowdsourcing platform with an online research panel. All responses (N = 212) were analyzed using SPSS 26.0 for the descriptive statistics, frequency analysis, reliability analysis, exploratory factor analysis, and PROCESS procedure. The results demonstrate that chatbot anthropomorphism increases chatbot reliability, and this is mediated by chatbot intelligence. Although chatbot anthropomorphism increases cognitive evaluation, the effect of cognitive evaluation on chatbot reliability is not significant; thereby, the effect of chatbot anthropomorphism on chatbot reliability is not mediated by the cognitive evaluation. The direct effect of anthropomorphism on chatbot reliability is also moderated by individuals' need for human interaction. For participants with a high need for human interaction, chatbot anthropomorphism increases chatbot reliability; however, anthropomorphism does not significantly affect chatbot reliability for participants with a low need for human interaction. The study's findings contribute to expanding the literature on consumers' new technology acceptance by testing the antecedents affecting service reliability.
