The purpose of this study is to analyze the current status of augmented reality picture books, which have been steadily developed since 2010, as a genre of electronic picture books, and to reveal how children's immersion in augmented reality picture books differs from paper picture books. To this end, 30 augmented reality picture books on the market were analyzed according to genre, life theme, implementation method, and augmented reality scene ratio. As a result of the study, it was found that the genre of picture books was in the order of information fairy tales, daily fairy tales, and historical fairy tales, and there were no traditional or fantasy fairy tales. Animals and plants accounted for about half of the life topics, and in some cases, there were only a few or no other life topics. In the augmented reality implementation scene, it consisted of only one page in the early days, but all pages are now possible to implement augmented reality due to technology development, production cost reduction, and improved hardware performance of smartphones. It was found that the augmented reality implementation method used CD-ROM in the early days, but gradually became possible to implement using only mobile phones and tablets that were easy for readers to access. In addition, after presenting four picture books to eight 5-year-old infants, the immersion time was measured and the immersion behavior was observed. As a result, augmented reality picture books showed higher immersion[immersion time, immersion behavior] than paper picture books, but compared by literature genre, life fairy tales were higher in paper picture books and natural fairy tales in augmented reality picture books. It was higher when presenting augmented reality picture books after presenting paper picture books according to the order of presentation of picture book types. The results of this study suggest that more diverse life topics and augmented reality picture books in the genre of children's literature should be developed to increase the utilization of augmented reality picture books. In addition, considering that there are differences in immersion between types, literary genres, and reading experience [presentation order], it is expected to increase the educational effect by using picture books complementarily.

In order to regulate cutting torque in milling, monitoring system should be set to a certain threshold. Radial immersion ratio is an important factor to determine the threshold and should be estimated in process for automatic regulation. In this paper, on-line estimation of the radial immersion ration using spindle motor current in face milling is presented. When a tooth finishes sweeping, a sudden drop of cutting torque occurs. This torque drop is equal to cutting torque acting on a single tooth at the swept angle of cut and can be acquired form cutting torque signals. Average cutting torque per revolution can also be calculate form cutting torque signals. The ratio of cutting torque acting on a single tooth at the swept angle of cut to the average cutting torque per revolution is a function of the swept angle of cut and the number of teeth. Using the magnitude of this ratio, the radial immersion ratio is estimated. Identical algorithm is adopted to estimate the immersion ratio based on the spindle motor current measurement. The experiments performed under different cutting conditions show that the radial immersion ratio can be estimated within 10% error range by the proposed method using spindle motor current.

21세기에 들어 입체영상에 대한 대중의 관심을 다시 집중시킨 곳은 극장이었다. 2009년을 기점으로, 입체영상에 대한 관심은 폭발적으로 증가했지만, 콘텐츠 부재 문제는 여전히 해결되지 못했다. 그러나 TV 방송 시장에서의 전망이 불투명한 반면, 입체영화는 할리우드를 중심으로 꾸준히 제작되고 있다. 또한 탄탄한 스토리텔링을 갖춘 영화들은 흥행에서도 괄목할만한 성적을 기록했는데, 이들의 공통점은 입체영상이 주는 공간감이 내러티브 몰입을 효과적으로 보조하고 있다는 점이다. 따라서 입체영상 기술은 극장을 중심으로 내러티브 몰입을 강화할 수 있는 시각기술로서 유용할 것으로 전망한다. 그래서 본 연구에서는 몰입과 입체영상의 관계를 살펴보고, 그에 대한 논의를 바탕으로 내러티브 몰입을 효과적으로 보조할 수 있는 입체영상의 공간연출 프로세스를 제안하였다.

Purpose: This study seeks to identify whether internal marketing factors have a statistically significant positive effect on the flow of services to customers of bank service employees. Specifically, the purpose of this study is to confirm the importance of internal marketing in the employees' services immersion to customers. In addition, the study seeks to identify whether employees' perceived organizational support recognition mediates between internal marketing factors and the employee's immersion in services to customers. Research design, data and methodology: This study distributed 100 questionnaires to employees working at banks to obtain data. Finally, the study conducted a statistical analysis on a questionnaire of 94 employees. For regression, factor analysis, and reliability analysis, the 24 version of the SPSS was used. For the mediation analysis, the SPSS macro developed by Hayes was used. Results: This study seeks to statistically verify which factors of internal marketing have a greater impact on employee immersion in services. Conclusions: Research verification has shown that all elements of internal marketing affect the employee's immersion in services to customers. It was also shown that the employee's recognition of organizational support mediated the relationship between factors of internal marketing and the employee's immersion in services to customers.

In tool condition monitoring systems, parameters should be set to a certain threshold. In many cases, however, the threshold is dependent on cutting conditions, especially the radial immersion ratio. In this presented is a method of on-line estimation of the radial immersion ratio in face milling. When a tooth finishes sweeping, a sudden drop of cutting force occurs. The force drop is equal to the cutting force that acting on a tooth at the swept angle of cut and can be acquired from cutting force signals in feed and cross-feed directions. Average cutting force per tooth period can also be calculated from cutting force signals in two directions. The ratio to cutting forces in two directions acting on a tooth at a certain swept angle of cut and the ratio of average cutting forces in two directions per tooth period are functions of the swept angle of cut and the ratio of radial to tangential cutting forces. Using these parameters, the radial immersion ratio is estimated. Various experiments are performed to verify the proposed method. The results show that the radial immersion ratio can be estimated by this method regardless of other cutting conditions.

The importance of magnesium alloys has significantly increased due to their low density, high strength/weight ratio, very good electromagnetic shielding features and good recyclability. However, unfortunately, Mg alloys are very susceptible to corrosion due to their high chemically activities (= -2.356 V vs. NHE at $25^{\circ}C$), hence, most commercial Mg alloys require corrosion protective coatings. Organic coating such as painting, powder coating and electrophoretic deposition of paint (E-paint) is typically used in the final stages of the coating process of Mg alloys. In this study, effect of pre-immersion time on the deposition of E-paint on AZ31 Mg alloy was investigated. It was found that during pre-immersion time, AZ31 Mg alloy rapidly reacts with E-paint solution and paint can be self-deposited on the AZ31 surface without applying of electric current. The pore size on the E-painted AZ31 Mg alloy increased with increasing pre-immersion time from 0 to 5 min. Both adhesion and corrosion resistance of E-painted AZ31 Mg alloy decreased with increasing pre-immersion time. The best E-paint AZ31 Mg alloy, which showed stronger adhesion after water immersion test and good corrosion resistance, was started to deposit after 5 s of pre-immersion time.

This study explores the effects of VR (Virtual Reality) store vividness, which is one of VR shopping environmental features used in previous research, on user satisfaction. In addition, the mediating role of immersion between VR store vividness and user satisfaction is investigated. The moderating role of self-efficacy is also explored since the effects of vividness and immersion on user satisfaction may depend on a consumer's perceived shopping self-efficacy. A total of 58 participants experienced a VR store with the Oculus Go VR headset. To test the hypotheses, model 14 of Process Macro 3.4 is used (95% Confidence Interval). According to the results, immersion mediated between VR store vividness and user satisfaction. Additionally, there was a significant interaction effect between immersion and self-efficacy on user satisfaction. When a consumer experiences high immersion at a VR store, consumers may have a strongly positive experience, especially among those who have a perceived low shopping self-efficacy.
