This study aimed to evaluate the masticatory performance of Korean children and adolescents and to investigate related factors. Early loss of primary molars, degree of occlusion of first molars, occlusal relationship of first molars, and presence of anterior crossbite were considered. From March 2020 to July 2021, 56 children and adolescents between the ages of 6 and 12 were included. The mixing ability index (MAI) was calculated to evaluate the masticatory efficiency of children and adolescents. The subjects were classified into three groups according to the number of early lost primary molars; normal dentition, 1 - 2 teeth lost, more than 3 teeth lost. The number of participants are 23, 18, and 15, respectively. There was no difference in the MAI values between the normal dentition group and the group has 1 - 2 teeth lost. However, when 3 or more primary molars were lost, the MAI value decreased and a significant difference was observed. This study is the first study to evaluate the masticatory performance of children and adolescents in Korea, and it will be helpful to pediatric dentists who evaluate the masticatory performance of children and adolescents and strive to improve the masticatory efficiency of children and adolescents in clinical practice.

In the plating process of the IC chips for the printed circuit board manufacturing, specification limits for the plating thickness are usually given but its target is not specified in most cases. When the target is not specified, the center point of the specification limits is used instead. When the process capability is large, however, the use of the center point for the target is not the best choice in the context of the total cost. In this paper, the total cost is defined in terms of the production cost and the loss function, and then the optimal choice for target is studied in order to minimize the expected loss. As a consequence, the optimal choice of the target reduces the expected loss significantly, while reducing the process capability slightly.

Methods : After three PBL packages for a semester of oral health education were developed, the PBL packages were evaluated by an expert to determine what improvements should be made. Results : The findings of the study were as follows. The three PBL packages were based on real clinical situations and designed to have a different degree of difficulty and provide problems in the form of scenario for learners to solve in a self-directed manner. When the packages were assessed by an expert, the packages were expected to make a contribution to the improvement of the three different abilities on which this study focused, and the packages were found to be appropriate in general in terms of learning content and field applicability, though they needed some modifications. Thus, this study attempted to develop PBL packages and let an expert assess the packages in order to give some suggestions about the development of PBL packages. The packages developed in this study are expected to help boost the problem-solving abilities, self-directed learning capabilities and communicative competency of dental hygienists, which should all be possessed by dental hygienists in the dental field. Moreover, the packages were found to be conducive to the introduction of PBL in the field of dental hygiene. Conclusions : To ensure the successful application of the packages, dental hygiene students should be provided with the packages in situations similar to real clinical situations, and they should have an opportunity to practice dental hygiene duties.
