The purpose of this research is to propose a design technique of concrete mix proportions satisfying service life through genetic algorithm (GA) and neural network (NN). For this, thirty mix proportions and the related diffusion coefficients in high performance concrete are analyzed and fitness function for diffusion coefficient is obtained considering mix components like w/b (water to binder ratio), cement content, mineral admixture (slag, flay ash and silica fume) content, sand and coarse aggregate content. Through averaging the results of 10 times GA simulations, relative errors to the previous data decrease lower than 5.0% and the simulated mix proportions are verified with the experimental results. Assuming the durability design parameters, intended diffusion coefficient for intended service life is derived and mix proportions satisfying the service life are obtained. Among the mix proportions, the most optimized case which satisfies required concrete strength and the lowest cost is selected through GA algorithm. The proposed technique would be improved with the enhancement of comprehensive data set including wider the range of diffusion coefficients.

Purpose: Recently, the managing customer complaints properly has emerged as key source of competitive advantage in the large distribution industry. Effective customer complaint management helps firms minimize service failures and incense the capability to respond to customer's needs. Despite this importance, the in-depth prior study of a firm's service failures is very limited. Therefore, the actual service failure cases of large discount stores in Korea were analyzed in this study, and the types of service failures that occur at the service interface were identified. Method: Specifically, a total of 48,307 cases of customer complaints that have occurred in the past three years were collected from 1 January 2016 to 31 December 2018. Using 7 dimensions of service marketing mix. we have classified and analyzed systematically the service failure cases collected. Results: Among the cases of service failures, 34,921 (72.3%) cases were involved with the product factor, followed by 6,152 (12.7%) cases with person factor and 5,392 (11.2%) cases with process factor. Conclusion: By linking the main causes of service failure with the service marketing mix variables, this research presented a more systematic analytic model and verified by applying it to large domestic distribution company. Understanding the main factors affecting customer complaints n the large distribution industry can provide managers useful information and insight who want to achieve an effective customer complaint management.

The purpose of this study is to investigate customer satisfaction factors that affect customer loyalty and revisit intention, and the seven factors which comprise the marketing mix that affects customer satisfaction. loyalty, and intention to revisit. The purpose of the project is to propose a research model by testing the mediated effects of customer satisfaction and loyalty using mainly factor analysis, regression analysis, and mediation analysis. First the results showed that the marketing mix 7P factors influence customer satisfaction were identified as service delivery process, product, physical basis, and promotion. The factors that influence marketing mix 7P customer loyalty were tested in the order of service delivery, physical basis, product, and distribution. Second, the factors that affect customer loyalty were artists, service, and prices whereas the factors that affect customer satisfaction were tested in the order of service, artist, cosmetics, and price. Third, the factors affecting customer revisit intention were newly derived as treatment satisfaction, professionalism, and treatment products. Fourth, the relationship between marketing mix and customer revisit intention suggested that customer satisfaction and customer loyalty has a partial sale effect. It can be suggested on the basis of these findings that the effect of makeup service with marketing mix on customer revisit intention was analyzed and a new model was derived by analyzing the mediated effect of customer satisfaction and customer loyalty.

The purpose of this study was to investigate the influence of service marketing mix on customers' perceptions of values at family restaurants in Seoul. Frequency analysis, ANOVA, reliability analysis, factor analysis, multi-regression analysis were employed to analyze the data. First, perceptions for items such as food (p<.001), price (p<.001), process (p<.001), and employees were significantly different with regard to monthly spending money, and food (p<.001), physical evidence (p<.001), and employees (p<.001) were also significantly different by partner. All of the mixes (food, price, place, employees p<.001; promotion, process, physical evidence p<.05) had positive influences on the customers' monetary and overall values. And the mixes of place p<.001; price and employees p<.01; and food, process and physical evidence p<.05 negatively affected non-monetary values, whereas promotion had a positive influence. As a result, we conclude that the service marketing mix is an efficient marketing tactic to remove intangible factors from restaurant businesses. Likewise it is highly recommended that food-service companies manage the marketing mix in a customerfriendly manner to minimize the negative characteristics of services toward customers, and to promote the customer appreciation of family restaurants.

본 연구는 중국에 진출한 글로벌 소매상을 대상으로 실증분석을 통해 서비스 마케팅믹스 요인이 현지고객의 만족도와 충성도에 미치는 영향력을 규명하고자 하였다. 이를 위해 선행연구를 근거로 3개의 연구가설을 설정한 후 구조방정식모형을 이용해 가설을 검증하였다. 분석결과, 서비스 마케팅믹스 요인이 고객만족에 직접 영향을 미치고, 고객만족은 충성도에 긍정적 영향을 미치는 것으로 나타났다. 하지만 서비스 마케팅믹스 요인이 충성도에 직접 영향을 미치지 않음으로써, 고객만족이 서비스 마케팅믹스와 충성도 간의 중대한 매개 역할을 한다고 판단할 수 있다. 또 서비스 마케팅믹스 7Ps 가운데 촉진을 제외한 다른 요인들은 모두 통계적으로 유의하게 나타났다. 비록 촉진요인의 신뢰도가 낮게 나타났지만, 글로벌 소매상들이 중국시장에 성공적으로 진출하기 위해서는 촉진을 포함한 서비스 마케팅믹스 요인을 현지 소비문화에 맞춰 적응 및 차별화할 필요가 있다는 점을 본 연구결과가 시사한다.

Considering the well known environmental issues of cement manufacturing (direct and indirect levels of $CO_2$ emissions), clinker replacement by supplementary cementing materials (SCM) can be a very promising first step in reducing considerably the associated emissions. However, such a reduction is possible up to a particular level of SCM utilization, influenced by the rate of its pozzolanic reaction. In this study a (4-step) structured methodology is proposed in order to be able to further adjust the concrete mix design of a particular SCM, in achieving additional reduction of the associated levels of $CO_2$ emissions and being at the same time accepted from a derived concrete strength and service life point of view. On this note, the aim of this study is twofold. To evaluate the environmental contribution of each concrete component and to provide the best possible mix design configuration, balanced between the principles of sustainability (low environmental cost) and durability (accepted concrete strength and service life ). It is shown that such a balance can be achieved, by utilising SCM by-products in the concrete mix, reducing in this way the fixed environmental emissions without compromising the long-term safety and durability of the structure.

기업의 경쟁력은 본질적으로 기업이 생산하는 제품이나 서비스의 가치에 의존한다. 왜냐하면 가치가 높은 제품이나 서비스는 고객으로 하여금 구매행동을 유발하기 때문이다. 서비스 믹스는 제품의 물리적 특성과 서비스의 최적결합을 통해서 고객을 위한 가치창출을 통해 경쟁력을 창출하는 프로세스이다. 본 연구에서는 기업에서 서비스 믹스가 기업경쟁력에 미치는 영향에 관한 연구를 통해서 우리나라 제조 기업의 경쟁력 향상에 기여하고자 한다. 경쟁우위를 위한 접근은 흔히 산업 구조 경쟁이론과 자원기반 관점 접근에 의존하고 있다. 그러나 산업 구조에 경쟁 이론은 어느 산업이 매력적인 산업 인가를 발견 하는 데에도 도움이 되지만 어느 기업은 특정의 산업에 진출하여 성공 할 수 있고 다른 기업은 실패하였는가에 대해서는 별다른 도움을 주지 못한다고 논의되고 있다. 자원기반 관점 절은 경쟁력 제고에 많은 공헌에도 불구하고 기업 전략 분석을 위한 이론이나 체계적인 틀은 제시하지 못하는 한계성이 있다. 본 연구에서는 이러한 한계성을 극복하고, 기업의 경쟁력 향상을 위하여 파워 프로세스 적 접근을 적용하였다. 파워프로세스는 권력요소, 가치, 욕구, 환경, 관계의 다섯 권력결정요소의 상호작용에 의해서 권력원천인 가치를 창출하는 프로세스이다. 즉 파워프로세스는 권력주체의 목적을 달성하기 위해서 권력객체를 만족시키는 가치를 창출하는 프로세스이다. 본 연구는 파워프로세스의 관점에서 서비스믹스 전략을 수립하여 우리나라 제조기업의 경쟁력 향상에 기여고자 한다.

The antibody-mix sandwich enzyme-linked immunosorbent assay (Ab-mix sELlS A) system was developed in order to simultaneously detect the extracellular polysaccharide (FPS) of Aspergillus, Penicillium, or Fusarium species using one detection system. The detection limit and detection range of the Ab-mix sELISA towards EPS of Penicilliun citrinum were not changed, and those towards Fusarium moniliforme EPS were changed a little compared to that of individual sandwich ELISA [9, 10]. The fungal culture filtrates of Aspergillus and Penicillium species showed nearly similar reactivity towards Ab-mix sELISA as that of sELISA using the MAb lB8 alone [9]. Also, the fungal culture filtrates of Fusarium species showed nearly the same reactivity towards Ab-mix sELISA as that of sELISA using the MAb lB8 alone [10]. Thus, this ELISA system showed that the three genera of molds, Aspergillus, Penicillium, or Fusarium, which are three major important molds producing mycotoxins in food or agricultural commodities, could be detected at the same time, using one detection system.

The study investigates how marketing mix factors are mediated by health consciousness and service quality in creating fresh fruit buying decisions of customers in Vietnam. This study employs samples of customers in Vietnam via the survey questionnaire. The authors have used a total of 256 responses that acquired the valid criteria. The compound of data analysis comprises reliability test, validity test, exploratory factor analysis, group analysis and multiple regression analysis to structure the hypothesized model. Respectively, the structural equation model (SEM) is applied to conduct the multiple multivariate equations. By the assumption of causal-effect relationship between independent variables such as marketing mixed factors, and mediator as health consciousness and service quality, which potentially impact on purchase decision; the SEM method is deployed. The results reveal that consumers have paid no attention to the marketing mix factors, but they care much about service quality and health consciousness. Thus, health consciousness and service quality are effective mediators. These findings are new and contribute to the consumer behavior and retail marketing literature. The findings of this study can provide assistance to managers in the given field to understand more easily the consumer behavior about fresh fruits, then improve their own performance.
