As the types of wedding ceremonies become diversified, and consumers' needs become more selective, greater importance is given to wedding planners' roles in the wedding industry, and consumers require differentiated types of wedding service. As a preliminary qualitative study in this field, an ethnographic study was conducted to identify factors valued by consumers when selecting a wedding planner in the wedding planner market, which has rapidly grown in recent years. An in-depth interview was performed with eight participants in terms of wedding planner utilization type and consumers' understanding of wedding preparation with a wedding planner. The collected data were analyzed through taxonomy, component analysis and decision table analysis; for validation, professional wedding planners were asked to review the items valued by consumers in selecting a wedding planner. Four factors - expense characteristic, wedding planners, wedding consulting companies, and customer characteristics - were identified, along with eight sub-factors (capability, service attitude, technical communication, personal factors, wedding planner encounter paths, spouse's satisfaction status, and companies). Out of these, price (within budget), wedding planners' capability, wedding planners' service attitude are expected to be meaningful in further research because they were found to be attributes commonly valued by every respondent. This study is significant in that it has made a new approach to understanding wedding planner selection attributes through ethnographic research and identified new wedding planner selection attributes.

Using the developed wedding planner selection criteria scale, this study examined whether wedding planner selection criteria differ according to consumer characteristics such as demographic characteristics and wedding preparation behaviors. The main survey for this study was conducted via the Internet with 295 consumers aged 20-30 living in the Seoul metropolitan area. The data collected from the survey processed and analyzed using the statistical programs SPSS 21.0 t-test. Analyzing how wedding planner selection criteria differ according to consumers' demographic characteristics and wedding preparation behaviors, results shown for the wedding planner selection criteria were all four points on average except for individual characteristics and important sub-factors regardless of the consumers' characteristics, and various results were derived depending on the consumers' characteristics. This study has various practical implications in that it verified the difference in wedding planner selection criteria according to consumer characteristics and determined how much money consumers were willing to play for wedding planners. It is recommended that future studies take various approaches to investigate how wedding planner users are satisfied with or place importance on wedding planner services and conduct empirical using the selection criteria developed in this study to compare influential variables that affect behavior intention and willingness to pay according to consumer type.

This study intends to develop a fixture planning module as a part of the planning system for cutting. The fixture module uses machine learning method to reuse previous failure results so that the system can reduce the repeated failures. Machine learning is one of efforts to incorporate human reasoning ability into a computerized system. A human expert designs better than a novice does because he has a wide experience in a specific area. This study implements the machine learning algorithm to have a wide experience in the fixture planning area as a human expert does. When the fixture planner finds a setup failure for the suggested operations by a process planner, it makes the process planner store its attributes and other information for the failed setup. Then the process planner applies the learned knowledge when it meets a similar case so that the planner can reduce possibility of setup failure. Also the system can teach a novice user by showing a failed setup with a modified setup.

In this study, additive manufacturing technology was applied to restore a planner miller that was unusable due to aging. The drive spur gear of the planner miller was inoperable due to many defects in the teeth. The shape of the defective gear teeth was restored by deposition of the defective teeth using the DED method. However, as the location of the deposition head and the location of the set origin became farther, the deposition shape was different from the modeling shape. Nonetheless, since the modeling of the deposition part was designed to be larger than the tooth shape of the original gear, it was possible to completely restore all gear teeth through post-processing. The arrangement interval of the flow lines of the deposition part was narrower than that of the substrate. The hardness of the substrate was 172 HV, and that of the deposition part was 345 HV, which was twice as high as that of the substrate.

In this study, we analyzed the instantaneous trajectory generation capability and target arrival rate of a mobile robot by changing the parameter of the TEB (Timed Elastic Band) Local Planner among local planners that affect the instantaneous obstacle avoidance ability of the mobile robot using ROS (Robot Operating System) simulation and real experience. As a result, we can expect a decrease in the target arrival time of the mobile robot through a decrease in the parameter values of the TEB Local Planner's min_obstacle_dist, inflation_dist, and penalty_epsilon. However, if this parameter is reduced too much, the risk of obstacle collision of the moving robot is increases, so it is important to combine the appropriate values to construct the parameter.

This study explores the meaning of life insurance planner's job experiences achieving job security, high performance and high income. After 6 of life insurance planners working in the field were chosen as the study participants, we use narrative approach to studying the meaning of their job experiences. The study shows that perception about job competency of planners depends on the level of experience: candidates who had no experience at all feel that anyone can perform planner's job, new employees after introduction training program see planners can do with product knowledge and consulting competency, and experienced people admit they can perform successfully only when they have good attitude towards customers and do all their work in a conscientious manner. Also, the meaning of planner's job experiences is identified as awareness of work value and serving customers with their commitment. The anticipated factors that make planner's job performed successfully are playing a role as a teacher, doctor, and angel, being regarded as happiness preacher for economic stability of individuals and families, and displaying their performance as experts.

This paper proposes a case study to treat planning and scheduling in factory of supply chain. In fact, the planning and the scheduling of a factory are not easily solved because of constraints of facility resources, material requirements, allowed planning times, and so on. However many packages are developed by vendors in Advanced Planning and Scheduling(APS) aspects to solve these problems. Therefore, in this paper, we analyze problems of an electronic company and apply the tool, Factory Planner(FP), to solve problems. The FP, which was developed by if technologies, is very popular planning and scheduling tool in the world. Also, the tool is successfully applied to many fields.

Identifying the selection criteria of wedding planners, who are the main human resource that contribute to the overall satisfaction level of a wedding's preparation, can produce important data for the wedding industry as it faces a transition period. To develop a scale for wedding planner selection criteria, preliminary items were prepared based on in-depth interviews with an experienced wedding planner group and a comprehensive review of previous studies, such as studies on selection criteria in the wedding industry and service work similar to wedding planners and wedding planner selection criteria. The preliminary items were tested for content validity using a focus group interview, comprising people in the wedding industry, and were refined accordingly. Then, the definitive quantitative questionnaire items were developed after conducting a preliminary survey. The main survey for this study was conducted using the responses of 295 consumers taking an Internet questionnaire. Exploratory factor analysis, Cronbach's alpha, and confirmatory factor analysis were adopted to develop the scale, which was tested for convergent validity and discriminant validity. This study is academically significant in that it developed a selection criteria scale tailored to wedding planners to address an area that has not been covered in previous studies. It is recommended that future studies conduct empirical analyses using the selection criteria developed in this study to compare influential variables that could affect behavior intention.

Since Lean Construction has been introduced as a new management approach to improve productivity in the construction industry, much research is in progress to develop lean concepts and principles for better implementation and to get results of the successful adaptation of lean ideas from manufacturing for application in the construction industry. Currently, Lean Construction Institute developed Last Planner System to achieve better workflow and effective planning management. Domestic construction companies are also getting interested in the Lean Construction. However, there are no detailed guidelines how to implement lean system. Thus, this study will provide a guideline for deployment of last planner system, a prototype lean implementation control checklist, and all project participants roles based on the case studies in USA. This study should provide a framework to apply lean construction to domestic construction sites.
