The research efforts to modernize Hanok (Korean traditional housing) have been performed to improve the quality and cost-effectiveness through application of modern building methods and materials, and to disseminate it in various forms of sizes and facilities. In this study, in order to identify the variations of modernized Hanok, data from seven test-bed projects are analyzed based on the building work-section, element, method, and material. The data were standardized and managed through the modernized Hanok classification system (Hanclass) to facilitate systematic comparisons of the test-bed projects by the variation of building method and it's cost impact. Identified factors of the variation in terms of building methods were then itemized and quantified in terms of building cost. Findings of this study indicate that the timber structure is the most critical area for future variation for improving the quality and cost-effectiveness. The results of this study will be also used to systemize the Hanok database for further studies.

In e-commerce, rapid and accurate automatic product classification according to product information is important. Recent developments in deep learning technology have been actively applied to automatic product classification. In order to develop a deep learning model with good performance, the quality of training data and data preprocessing suitable for the model are crucial. In this study, when categories are inferred based on text product data using a deep learning model, both effects of the data preprocessing and of the selection of training data are extensively compared and analyzed. We employ our CNN model as an example of deep learning model. In the experimental analysis, we use a real e-commerce data to ensure the verification of the study results. The empirical analysis and results shown in this study may be meaningful as a reference study for improving performance when developing a deep learning product classification model.

Detection and classification of steel surface defects are critical for product quality control in the steel industry. However, due to its low accuracy and slow speed, the traditional approach cannot be effectively used in a production line. The current, widely used algorithm (based on deep learning) has an accuracy problem, and there are still rooms for development. This paper proposes a method of steel surface defect detection combining EfficientNetV2 for image classification and YOLOv5 as an object detector. Shorter training time and high accuracy are advantages of this model. Firstly, the image input into EfficientNetV2 model classifies defect classes and predicts probability of having defects. If the probability of having a defect is less than 0.25, the algorithm directly recognizes that the sample has no defects. Otherwise, the samples are further input into YOLOv5 to accomplish the defect detection process on the metal surface. Experiments show that proposed model has good performance on the NEU dataset with an accuracy of 98.3%. Simultaneously, the average training speed is shorter than other models.

The Banking industry is expanding rapidly. To keep the competitive advantages, participating companies concentrate their resource to provide the distinguishable services by increasing the service quality. This study is to find that how three kinds of service quality(process, output, and service environment) affect on the customer satisfaction. In this paper, WPCSI (Weighted Potential Customer Satisfaction Index) was developed using Kano model and PCSI. Kano's model of service quality classification was used to improve customer satisfaction, customer satisfaction index was calculated. Customer satisfaction index was calculated using the existing potential for improving customer satisfaction index (PCSI Index) to complement the limitations of the weighted potential improve customer satisfaction index (WPCSI) were used. Analysis using PCSI improve the quality of service levels may be useful in assessing. However, this figure is a marginal degree of importance on customers and quality characteristics have been overlooked but has its problems. A service provided to customers with some important differences depending on the interpretation of the scope for improvement is to be classified. In other words, the level of customer satisfaction and the satisfaction of the current difference between the comparison factor for the company to provide information about the priority of the improvement was not significant. Companies are also considered important that the customer does not consider the uniform quality of service provided can be fallible. In this study, the weighted potential to improve it improve customer satisfaction index (WPCSI) proposed a new customer satisfaction index. This is for customers to recognize the importance of quality characteristics by weighting factors, to identify practical and improved priority to provide more useful information than has been. Weighted potentially improve customer satisfaction index (WPCSI) presented in this study by the customers aware of the importance of considering the quality factor is an exponent. The results, 'Employees' working ability', 'provided the desired service level', 'staff to handle this task quickly enough' to the customer of the factors had significant effects on satisfaction are met. On the other hand 'aggressiveness on the product description of employees', 'service environment as a whole, beautiful enough to' meet and shows no significant difference between satisfaction. But 'aggressiveness on the product description of employees' and reverse (逆) were attributable to the quality. Small dogs and overly aggressive products that encourage the customer dissatisfaction that can result in widening should be careful because the quality factor can be said. As a result, WPCSI is more effect to find critical factors which can affect customer satisfaction than PCSI. After that, we discuss effects and advantages of customer satisfaction using WPCSI. This study, along with these positive aspects, the limitations are implied. First, this study directly to the bank so that I could visit any other way for customers, utilizing the Internet or mobile to take advantage of the respondents were excluded from the analysis. Second, in survey questionnaires can help improve understanding of the measures will be taken. In addition to the survey targeted mainly focused on Seoul, according to a sample, so sampling can cause problems is the viscosity revealed intends.

많은 기업들이 기업 내 또는 기업간 통합을 위해 웹서비스 시스템을 도입, 구축하고 있다. 하지만 기업관리자들은 기대했던 만큼의 실질적인 성과를 체감하고 있지 못하며 투자효과 분석 또한 미흡한 실정이다. 현재 웹서비스의 평가는 웹서비스의 서비스 품질 관리측면에서의 분석이 이루어 지고 있으며 웹서비스가 기업의 비즈니스에 가져다 주는 가치분석에 대한 연구는 미흡한 실정이다. 본 연구에서는 선행연구를 통해 웹서비스의 도입으로 인해 기업에 발생하는 이익을 분석하여 기술적 가치와 비즈니스적 가치로 분류하고 이를 바탕으로 가치의 측정을 위하여 웹서비스의 이익을 비용절감과 가치증대의 관점으로 새롭게 정립하였다. 본 연구의 결과는 기업이나 공공기관에서 웹서비스의 이익을 인식하는 새로운 방법으로 활용될 수 있을 것이다.
