The rising demand for fashion do-it-yourself (DIY) products that cater to individual preferences and which allow for creative expression has highlighted the need for systematic organization within the clothing society. This study addresses this gap by identifying and discussing clothing DIY packages and proposes a systematic package model comprising essential raw materials, commercial patterns, and production instructions. Four key elements have been emphasized to differentiate and enhance the product. Firstly, highly practical commercial patterns have been developed to facilitate easy transformations - from blouses to dresses. Furthermore, the versatility of these patterns has been optimized so as to allow their utilization as outerwear, increasing their efficiency. Secondly, to accommodate diverse body shapes, the package offers six different sizes, providing users with a range of options tailored to their specific measurements. Thirdly, detailed production instructions are provided, supplemented by a Q&A bulletin board. The instructions are available in a printed format, featuring actual photographs on A4 paper, while video production instructions are accessible via a QR code, ensuring comprehensive guidance. Lastly, the basic package comprises clothing patterns, production instructions, fabrics, and labels, providing a complete toolkit for clothing DIY enthusiasts. This study aims to contribute to the development of the hobby sewing field and to establish a practical resource for the clothing DIY package industry.

The purpose of this study was to investigate the middle school students' perception and their learning satisfaction in SMART learning based science instruction. Three types of modules on the solar system and lunar phases unit at the middle school level were developed and lessons on each module were taught to 207 student participants. All participants were provided with tabletPC(iPad2) with iOS5 installed, and using astronomy app Solar Walk, mirroring function, QR code, and Google Presentation, the lessons were carried out both in classroom and at home. The instrument for assessing students' perception on the SMART learning-based instruction was developed based on 4 factors including Self-directed, Motivation, Adaptiveness, and Technology Embedded, with a Likert scale from 1-5 on 20 items. The learning satisfaction survey instrument was originally from Keller's work (1987), and its test items were adapted and modified. To reveal the perception and learning satisfaction about SMART learning-based science lessons, the participants were comparatively analyzed by gender and science achievement levels. Results indicated that male students showed positive perception for the SMART learning-based instruction. Group with higher science achievement scores showed more positive perception of the SMART learning-based instruction in terms of Self-directed and Motivation factor. Also, the learning satisfaction of male students was higher than female students and group with higher academic ability more satisfied with the SMART learning-based instruction than the low group. The results provide implications for future development of programs and help set a direction of increasing the use of a SMART learning-based science in school.

This study examined users' awareness to establish futurity of libraries and to propose strategies in the era of the $4^{th}$ Industrial Revolution. For this purpose, the awareness survey was conducted of users, and the survey consisted of questions about the awareness of the $4^{th}$ Industrial Revolution, the current state of using technologies and devices of the $4^{th}$ Industrial Revolution, and the futurity of libraries of the $4^{th}$ Industrial Revolution. The results are as follows: First, users were interested in the $4^{th}$ industrial Revolution, but they thought that new technologies are poorly adopted in the libraries. Second, users were most frequently using mobile phone, QR code, and Beacon. Especially, mobile phone was a most frequently used device in the libraries. However, users were not satisfied with technologies and devices provided by the libraries. Third, users expected the $4^{th}$ Industrial Revolution have a positive influence on future of libraries, but they were worried about losses of opportunities and jobs. Forth, users agreed with necessity of new technologies of the $4^{th}$ Industrial Revolution for libraries services. They wanted application of the technologies, expecially, in online services. Ultimately, this study suggested some meaningful insights and strategies through comparative analysis of the above findings and librarians' awareness survey results.

Currently, systems for finding missing children are composed of using communication between a QR code and RFID chip, as the use of a smartphone. However, the current systems for finding missing children have limitations in that children can only be found if there are people in the surrounding area; there is an economic burden on parents required to purchase a smartphone for their children; along with difficulties in finding the missing children without the assistance of those in the surrounding area in critical situations such as a kidnapping, due to the limited duration of the battery life. In order to solve such problems, approaches need to be made from two perspectives: having someone in the surrounding area; and absence of anyone in the surrounding area. This thesis is centered on the development of a IoT (Internet of Things) system for finding missing children that combines two methods, namely, the method of finding missing children without a guardian in the surrounding area -within the limited space in which AP is installed by using a beacon and open source hardware being highlighted as the IoT technology - and the method of finding missing children with the smartphone application in which each individual becomes the Access Point (AP). The Main purpose is to provide accurate information of missing children's location for the 2situations and it is found that the accuracy of smartphones APP is 97.7% and security device AP is 91.1%.
