Building on Technology Readiness and Acceptance Model(TRAM), the study aimed to examine how technology readiness affects consumers' perceptions of ease of use, usefulness, and risk, which in turn predict their intention to use retail service robots. Specifically, the study proposed that technology readiness motivators (optimism and innovativeness) would influence perceived ease of use and usefulness, while technology readiness inhibitors (discomfort and insecurity) would affect perceived risk. The study further examined if the perception factors (ease of use, usefulness, and risk) contribute to intention to use retail service robots. A survey method was used with data collected from Korean consumers. The final sample size was 418. The data was analyzed using structural equation modeling. Findings of the study revealed that technology readiness motivators positively affected perceived ease of use and usefulness while innovativeness had no impact on usefulness. All the inhibitors increased perceived risk. Lastly, as hypothesized, perceptions of ease of use, usefulness, and risk predicted intention to use retail service robots. This study extended the retail technology literature by applying and validating TRAM to the context of consumer acceptance of retail service robots. The study further helped marketers and retailers by highlighting the importance of technology readiness in improving consumer perceptions and responses towards retail service robots.

Laser surface hardening is an effective technique used to improve the tribological properties and also to increase the service life of automobile components such as camshafts, crankshatfs, lorry brake drums and gears. High power CO2 lasers and Nd:YAG lasers are employed for localized hardening of materials and hence are of potential application in the automobile industries. The heat is conducted rapidly into the bulk of the specimen causing self-quenching to occur and the formation of martensitic structure. In this investigation, the microstructure features occurring in Nd:YAG laser hardening SM45C steel are discussed with the use of optical microscopic and scanning electron microscopic analysis. Moreover, This paper describes the optimism of the processing parameters for maximum hardened depth of SM45C steel specimens of 3mm thickness by using CW Nd:YAG laser. Travel speed was varied from 0.6m/min to 1.0m/min. The maximum hardness and case depth fo SM45C steel are 780Hv and 0.4mm by laser hardening.

Aim of this article is to propose Micro-Genetic Simulated Annealing (${\mu}GSA$) as a hybrid metaheuristics approach to find the global optimum of nonlinear optimisation problems. This approach combines the features of modern metaheuristics such as micro-genetic algorithm (${\mu}GAs$) and simulated annealing (SA) with the general robustness of parallel exploration and asymptotic convergence, respectively. Therefore, ${\mu}GSA$ approach can help in avoiding the premature convergence and can search for better global solution, because of its wide spread applicability, global perspective and inherent parallelism. For the superior performance of the ${\mu}GSA$, the five well-know benchmark test functions that were tested and compared with the two global optimisation approaches: scatter search (SS) and hybrid scatter genetic tabu (HSGT) approach. A practical application to structural sandwich panel is also examined by optimism the weight function. From the simulation results, it has been concluded that the proposed ${\mu}GSA$ approach is an effective optimisation tool for soloing continuous nonlinear global optimisation problems in suitable computational time frame.

The goal of this research, contorted from the perspective of media aesthetics, is to uncover the ways how mechanical/cybersensual fashion products express aesthetic characteristics of cybernetics, by comparing them with digital products designed by an application of cybernetics. The other goal is to provide a cultural and design framework of cybernetics as d digital-environmental medium for fashion in which hightech and human sensibilities are fused. The results urged to explore two new contrasting perceptual possibilities for an understanding of digital technology application: negative and positive feedbacks. Cybernetic optimism, centered on technological dimensions, focuses on a concept of fashion that emphasize instrumental aspects-efficiency and convenience. In contrast, cybernetic pessimism focuses on digital fashion that expresses environmental destruction and the loss of human identity. A comparative analysis of the aesthetics of expression in digital fashion design and digital industrial products from a cybernetic perspective showed that in digital environment society, the combination of negative and positive feedbacks resulted in design products in which internal and external aspects of beauty complemented each other.

To examine the psychological characteristics and work ethics of Hanwoo managers, we selected 26 of the 50 managers who took part in this study to avoid unreliable response and non-description from the questionnaire. The core results of this study were the following: First, cronbach's ${\alpha}$ reliability with highest domain in this study were obtained from character strengths (.938), followed by job satisfaction (.841), internal evaluation (.799), and external evaluation (.739). Second, for perception and attitude of Hanwoo management, the correlation between job satisfaction and internal evaluation (P<0.05) was observed. Management satisfaction showed higher for intermediate group and subgroup and lower satisfaction for the top group. Third, there were statistical differences (P<0.05) in ten character strengths (curiosity, judgment, creativity, social intelligence, wisdom, honesty, optimism, responsibility, humor, and passion) according to group satisfaction. Ten character strengths were lower in creativity (7.14) and higher in responsibility (8.57) in comparison with other items for the top group. In conclusion, these results suggest that character strengths are beneficial to improve Hanwoo management on psychological characteristics and work ethics of managers.

Objective : The aim of this study was to investigate the relationship between trait anxiety and positive psychological factors. Methods : A total of 429 outpatients diagnosed with depression and/or anxiety disorders surveyed with questionnaires measuring socio-demographic, clinical, and positive psychological factors. The relationships of trait anxiety with clinical symptoms and positive psychological factors were evaluated. Results : Patients with low trait anxiety showed high optimism, gratitude, hope, spirituality and purpose in life. After adjusting age, scores of BDI and STAI-S, the results showed low trait anxiety was associated with high spirituality and purpose in life. Conclusion : The result revealed that trait anxiety had negative-relationship with spirituality and purpose in life in patients with depressive and/or anxiety disorders. Although trait anxiety was known as a general tendency which is stable, approach to trait anxiety by modulating these associated positive psychological factors would be newer approach of treatment to patients with depressive and/or anxiety disorders.

The purpose of this study was to assess the degree of stress and patterns of coping for that Stressful events on family members because of the hospitalization of the patients. Stress and coping were measured with a tool on the basis of Volicer and Bell's questionnaire. In data collection, the modified 38 items of Volicer's stress scale and Bell's 18 item coping scale were administered. The subjects consisted of 259 family members of general ward-patients in Seoul National University Hospital during April in 1990. They were randomly selected on the basis of relationship of patients; patient's spouse, patient's daughters or sons. The stressors of the family members were ranked as follows; The first rank Stressful events was related to the patient's diseases and pain, the second ones was related ·to caring of their patients and family's psychosocial life. Families used long term coping method significantly more than short term ones. The results indicated that there was no difference in use of coping method between pre and post hospitalization. Finding out more about situation and optimism were the most common coping methods, and the least frequent coping method was the use of drugs. In conclusion, the identification of perceived stress and coping patterns of family members provides useful information for family nursing and aimes at better nursing care for the hospitalized in patients.
