In order to understand the difficulties and overcoming effort in teachers of Employer-Supported Child-Care Center in the attitude of parents, this study explored seven teachers of Soie Child-Care Center that operated for 18 hours a day, 365 days a year. Seven teachers were interviewed and the data were analyzed utilizing content analysis. The results of the study came out that Teachers experience difficulties such as parents' non-regulations, excessive use, excessive individual demands, excessive sensitivity in case of safety accidents, the connection of parental rank to the classroom, excessive service demands. In order to overcome this problem, participants used methods such as identifying sensitive parts of parents, seeking advice, objectifying situations, and enhancing professionalism. This will be basic data for the expanding operation of Employer-Supported Child-Care Center and the development of programs to support teachers.

Logical Effort [1, 2] is a simple hand-calculated method that measures quick delay estimation. It has the advantage of reducing the design cycle time. However, it has shortcomings in designing a path for minimum area or power under a fixed-delay constraint. The method of overcoming the shortcomings is shown in [3], but it is constrained for a single logical path. This paper presents an advanced gate sizing method in multiple logical paths based on the equal delay model. According to the results of the simulation, the power dissipation for both the existing logical effort method and proposed method is almost equal. However, compared with the existing logical effort method, it is about 52 (%) more efficient in space.

This study used the qualitative research for deeply interviewing Chinese-Koreans who live and work in Dearim-dong area, Yeongdeungpo-gu, Seoul, collectively. The variation of recognition to the local community at the migration early and the present and their response for overcoming their pending issues are studied through this, To understand the reality and conflict they encounter, the effort for overcoming the pending issues, the inner change of their own community, their fixed direction and so on becomes the core variables for integrating them to our society. They have formed the enormous cluster and have been already developed as the minority group. They are doing 'the struggle for recognition' for being recognized from the dominant group and trying to approach the politics for overcoming the inferiority of power. Accordingly, the intervention of social welfare to this minority group should be a more active working to protect the fragmentation of our society which can be resulted from the increasing influx of the foreigners and be also an approach to mutual enlightenment for making our society adapt to the phenomena of multi-nations and multi-cultures and for accepting them as the population.

This study is to suggest the tasks of Christian Education for developing empathic emotional ability of women in AI era through examining the meaning of empathic sensibilization and the examples of women overcoming the hardships of their times and bringing about change. Empathic sensibility is becoming a issue and empathy is emphasized in AI era. Because empathy is becoming a big support in overcoming hardships, and empathic emotion is showing human dignity, equality, service, devotion and consideration and so is forming a global community living together. And on investigation of the examples of women overcoming the hardships of their times, I found that as a woman with a sense and thought, as a historical human being, not as a gender, the tasks of Christian Education for developing empathic sensibility ability of women in AI era will be effort to be yourself, theological identity reestablishment of women and developing insight to read the times.

Purpose The purpose of this study is to predict future behaviors of business process. Specifically, this study tried to predict the last activities of process instances. It contributes to overcoming the limitations of existing approaches that they do not accurately reflect the actual behavior of business process and it requires a lot of effort and time every time they are applied to specific processes. Design/methodology/approach This study proposed a novel approach based using deep learning in the form of dynamic recurrent neural networks. To improve the accuracy of our prediction model based on the approach, we tried to adopt the latest techniques including new initialization functions(Xavier and He initializations). The proposed approach has been verified using real-life data of a domestic small and medium-sized business. Findings According to the experiment result, our approach achieves better prediction accuracy than the latest approach based on the static recurrent neural networks. It is also proved that much less effort and time are required to predict the behavior of business processes.

The objective of this study is to present a new design method at the idea brainstorming process, which requires a great deal of time and effort to seek their own ideas in existing design process and to develop a user support idea forms generation system called OCIGS (Openware Creative Idea Generation System) that makes it possible to create a variety and 3D forms as well as a quantitative evaluation data for the actual types that compose the aesthetic factors and designs of qualitative standards. In order to achieve these objectives : First, overcoming the limitation of 3D form generation ability by establishing visual application system, Second, accepting users' opinions by generating 3D images dynamically, analysing and giving information on the preferred ones on the web on real time, Third, identifying tendency of preference so that they can generate preferred colors and images in future by updating image combination and dropping low-preferred ones. This system would play a role as an idea or form generation application in the actual 3d form design development process.

Although the theory of stellar structure and evolution is considered one of the most successful developments in astrophysics, there still remains a significant mismatch between theoretical stellar models and the observed main sequence of the best studied nearby open clusters. To ease the tension, empirical corrections to the color-temperature transformations are used as a simple, but practical way of overcoming the difficulty than directly examining stellar atmosphere models that have large theoretical complexities and uncertainties. I will describe our continuing effort to calibrate stellar isochrones using cool main-sequence stars in Praesepe, complementing our previous work based on the Hyades and the Pleiades, and provide an extensive test of our models using photometry of cool and metal-rich main-sequence stars in NGC 6791. Finally, I will discuss the implication of our results on the mass loss in NGC 6791.

So many groups have been researching the green quantum dots such as InP, InP/ZnS for overcoming the semiconductor nanoparticles composed with heavy metals like as Cd and Pb so on. In spite of much effort to keep up CdSe quantum dots, it does not reach the good properties compared with CdSe/ZnS quantum dots. This quantum dot has improved its properties through the generation of core/shell CdSe/ZnS structure or core/multi-shell structures like as CdSe/CdS/ZnS and CdSe/CdS/ CdZnS/ZnS. In this research, we try to synthesize the InP multi-shell structure by the successiveion layer absorption reaction (SILAR) in the one pot. The synthesized multi-shell structure has improved quantum yield and photo-stability. To generate white light, highly luminescent InP multi-shell quantum dots were mixed with yellow phosphor and integrated on the blue LED chip. This InP multi-shell improved red region of the LEDs and generated high CRI.

Micro tensile test is the most direct and convenient method to measure material properties such as Young's modulus and fracture strength. It, however, needs more accurate measurement system, mote stable and repetitive alignment and more sensitive gripping than conventional tensile test. Many researchers have put their effort on overcoming these difficulties for tile development of micro tensile tester, fabricating micro specimens of functional materials and measuring their properties. This paper will review the related vigorous researches over the world in the recent decade and explain how to apply them to a design of the fester which is under our own development.
