The purpose of this study is to explore undergraduate students' self-growth experiences in a counseling skills training course. Participants of this study were seven students who completed the counseling skills course in a university. The analysis was done on the weekly reflective journals they had written during the course using Colaizzi's phenomenological qualitative method. As a result, 26 themes and 11 theme clusters which emerged: projecting oneself onto client, exploring interpersonal dynamics, approaching one's emotions, discovering oneself that he was not conscious of, examining connection between the present and the past, experiencing difficulties due to facing self, feeling concerned about performing a role as counselor, increasing growth motive, finding value of self-awareness, trying new actions, expanding acceptance of oneself and others. Likewise, undergraduate students were experiencing self-growth in a variety of aspects. This study has implications in that it shed a rich light on the self-growth of a counselor that has not received much attention so far. In the future, this study can be utilized in the development of holistic counseling training programs that would systematically facilitate counselors' self-growth.

The purpose of this research is to investigate ways to introduce mentoring system to support beginning and experienced teachers for their professional development. As an alternative to existing teacher training programs, we planned and implemented a mentoring system to examine its effects in developing professionalism among teachers-in-need, and those who have not met the teacher's evaluation standards. Mentoring is defined as being concerned with promoting the 'development of an individual to his/her full potential,' both professionally and personally. It is linked with professional and career development, and is somewhat characterized by an 'expert-novice' relationship. The mentoring system in science features group mentoring, where 3 prot$\'{e}$g$\'{e}$-mentor teams gathered together for instructional consulting using their videotaped classroom teaching. Through video-based discussions, teachers could share reflective experiences through collaborative investigations based on evidences revealed in classroom teaching videos. Using open-ended interviews with the teachers and video-based discussions, we extracted needs and goals of mentoring, the need of mentoring system to support beginning teachers, and the requirement of mentor quality in light of mentor's expected roles. Conclusions and recommendations related to teachers' mentoring and for the government's development of mentoring system are discussed.

The actor Song Gang Ho who appeared in the late 1990s, expanded the personality of his characters on his own way by using his unique characteristics (way of talking and appearance) as a nuance of diverse characters, while playing the wide range of roles from the petite bourgeoisie to kings in various genres. Especially in films such as , which are based on real incidents and real people, Gang Ho Song's character embodies Korean history and cultural identity. Not only his serious, but light and seemingly uncalculated realistic acting style harmonizes with his character and reveals the sense of humanity creating a new genre called "Gang Ho Song's character", but also Gang Ho Song is solidifying his base and range as an actor. Therefore, this research aims to analyze his character and acting through the film while concentrating on his realistic expression and creativity based on Barry King's concept of authorship. First, the research will analyze the features of the historical and cultural identity of Song Gang Ho's character which reenacts the real people and incidents as well as analyzing his realistic acting and improvisation of his acting which adds vibrancy to his character. While looking at Song Gang Ho's acting as a self-reflective acting, he enhances the character's reality by creating the character's personality using his own physical features and this research will analyze how Song Gang Ho's self-reflectiveness harmonizes with the character's features which are expressed realistically in the film and how his character and acting creates a continuum.

The purpose of the study is to reflect on 'myself' as a teacher educator of college of education in depth and to improve my instruction through self-study with three critical collaborators. 17 pre-service science teachers and I have participated in this study of a teacher educator's course since March 2016 after the preliminary practice in 2015. The video recorded the course for 11 weeks with about 40 hours of lessons. The data source also included teacher educator's reflective journals, lecture evaluations, online boards and so on. Questionnaires were distributed and answered both at the beginning and at the end of the course and pre-service teachers wrote their reflective journals. Four of them were in the focus group interviews. During the course, the weekly group meeting of critical collaborators analyzed the emerging issues based on the lesson clips and teacher educator's reflective journals with discussion for the course innovation. Four phases were revealed in the process and for the purpose of the course such as exploration, conflicts, challenges, and changes. The results showed that first, we identified tensions among the teacher educator's multiple identities as a lecturer, a faculty member, and a researcher. Second, there were differences between goals of teacher educator and pre-service teachers in the course, and this obstructed the success of the course sometimes. Third, these practices led to explore balanced alternative views and interpretations of the problem by critical views and to expand and improve our teaching practice and thinking. In addition, the self-study with critical collaborators helped to bring conflicts and issues below my practice to light for collaborative reflection and it gave a chance to understand ourselves as teacher educators in different ways.

This study is to investigate the meaning of pre-service educare teachers' leadership experience about program development. The participants were 41 juniors in college, majoring in Child Welfare. They attended an 'infant & young childhood educare program development and evaluation' class for 15 weeks. During the given period they made documents from reflective journals and 5 participants among them were interviewed individually. Analyzing the documents sheds light on the meaning of the pre-service educare teahcers' experience. The results are as follows. First, pre-service educare teachers got a deeper understanding and attachment about communities. Second, they did a critical analysis about well-known home and abroad educare programs. Third, they had a opportunity of reflection about their education philosophy and competences. Forth, they experienced diverse leadership that is needed from educare teacher. The results showed the implications and suggestions about pre-service teacher education for educare teacher's curriculum leadership development.

The NISS onboard NEXTSat-1 is being developed by Korea astronomy and space science institute (KASI). For the study of the cosmic star formation history, the NISS performs the imaging spectroscopic observation in the near-infrared range for nearby galaxies, low background regions, star-forming regions and so on. It is designed to cover a wide field of view ($2{\times}2$ deg) and a wide wavelength range from 0.95 to $3.8{\mu}m$ by using linear variable filters. In order to reduce the thermal noise, the telescope and the infrared sensor are cooled down to 200 K and 80 K, respectively. Evading a stray light outside the field of view and making the most use of limited space, the NISS adopts the off-axis reflective optical system. The primary and the secondary mirrors, the opto-mechanical part and the mechanical structure are designed to be made of aluminum material. It reduces the degradation of optical performance due to a thermal variation. This paper presents the study on the conceptual design of the NISS.

In this paper, we propose a method that can generate a computer-generated hologram (CGH) from the depth stream and color image outputs provided by an active sensor add-on camera. Distinguished from an existing holographic display system that uses a computer graphic model to generate CGH, this method utilizes a real camera image including a depth information for each object captured by the camera, as well as color information. This procedure consists of two steps that the acquirement of a depth-annotated image of real object, and generation of CGH according to the 3D information that is extracted from the depth cue. In addition, we display the generated CGH via a holographic display system. In experimental system we reconstruct an image made from CGH with a reflective LCD panel that had a pixel-pitch of 10.4um and resolution of 1408X1050.

LiDAR, unlike satellite imagery and aerial photographs, which provides irregularly distributed three-dimensional coordinates of ground surface, enables three-dimensional modeling. In this study, urban area was classified based on 3D information collected by LiDAR. Morphological and spatial properties are determined by the ratio of ground and non-ground point that are estimated with the number of ground reflected point data of LiDAR raw data. With this information, the residential and forest area could be classified in terms of height and density of trees. The intensity of the signal is distinguished by a statistical method, Jenk's Natural Break. Vegetative area (high or low density) and non-vegetative area (high or low density) are classified with reflective ratio of ground surface.

The green displays are the human friendly displays, the nature friendly displays, and the economical displays. Electrochromic displays are low cost and environmental devices because they do have more choice of colours and use much less power. The elements of the electrochromic devices consist of at least two conductors, an electrochromic material and an electrolyte. The optical properties were obtained using the optical contrast between the transparency of the substrate and the coloured state of the electrochromic materials. These devices can be fully flexible and printable. Due to the characteristics of the high coloration efficiency and memory effects, the electrochromic devices have been used in various applications such as information displays, smart windows, light shutters and electronic papers. Among these technical fields switchable mirrors have been received much attention in the applicative point of view of various electronic devices production. We have developed a novel silver (Ag) deposition-based electrochromic device for the reversible electrodeposition (RED) system. The electrochromic device can switch between transparent states and mirror states in response to a change in the applied voltage. The dynamic range of transmittance percent (%) for the fabricated device is about 90% at 550 nm wavelength. Also, we successfully fabricated the large area RED display system using the parted electrochromic cells of the honey comb structure.

Head-Up Display, an information-providing display, is a device that provides necessary information through a vehicle window for a driver when driving, with which the driver secures the visibility and acquires information necessary for driving. Head-up displays in early days were mostly installed in imported vehicles but increasingly, being installed in medium and large-sized domestic vehicles, they secures convenience of driving and information acquirement. The information display element of each of currently released brand cars not only has limits in consistency and in displaying interface but also reveals the limitation of a way to apply GUI, being applied to dot reflective form in terms of the technology type. Accordingly, this study draws real time information element described as necessary during driving through case survey and analysis, and aims to provide a user with new GUI guideline through transparent display technology recently developed based on results analyzed with priority of POI(Point of Interest) information.
