The purpose of this study was to examine the effects of the We Start center visiting intervention program on the positive changes in the developmental areas and literacy interests of young children from low-income families. The subjects were 195 young children (109 in the experimental group, M=71.7 months; 86 in the control group, M=73.3 months) living in We Start areas (Ansan, Gwangmyeong, and Suwon cities) of Gyeonggi-do. The We Start center visiting intervention programs were conducted for 30-34 weeks in each city, and pre-tests and post-tests were conducted before and after the intervention programs. The instruments used were the developmental checklist and the literacy interests test The developmental checklist consisted of 7 domains (personality & sociality; language, reading, & writing; scientific thinking; mathematical thinking; arts; social learning; and physical development). The literacy interests test consisted of 2 factors (interest in literacy and interaction during activity). The scores on the developmental checklist showed positive changes in several domains (personality & social development; language, reading, & writing ability; scientific thinking; and social learning), but not in mathematical thinking, arts, and physical development. Second, the results of the literacy interests test showed positive effects on interaction during activity and the total score. In conclusion, the We Start center visiting program for young children from low-income families is an effective early intervention program to end the intergenerational transference of poverty in Korea.

Multimedia has created a system environment that needs a combination of diverse peripherals, faster I/O, and easier configuration. The sheer volume of data one can expect with multimedia hardware and applications storage systems of higher capacity and faster data transfer rate. Unlike the magneto-optical(MO)disk technology which uses bias magnetic field in writing, both the reading and the writing in the phase change (PC) technology are performed only by laser light. In PC optical media, an active layer is reversibly converted between amorphous state and crystalline state by changing irradiation conditions of focused laser beam. Thus, as compared with MO disk, the PC disk has such great advantages that signals can be reproduced by change of reflectance of laser beams in the same manner as the compact disc. The reflectivity of a phase-change spot can be altered in a single pass under the head only through modulation of laser power. The principles and the current status of phase-change optical recording media combined with possible applications are discussed in the present article.

Objectives: This study aimed to analyze the educational needs of interns and residents in Korean medicine as the first step in developing an education program to improve their research competencies. Methods: A mixed-method design, incorporating both quantitative and qualitative data collection methods, was used to investigate the educational needs for research competencies among interns and residents working in Korean medicine hospitals nationwide. Data were collected through online surveys and online focus group discussions (FGDs), and processed using descriptive statistical analysis and thematic analysis. The study results were derived by integrating survey data and FGD outcomes. Results: In total, 209 interns and residents participated in the survey, and 11 individuals participated in two rounds of FGDs. The majority of participants felt a lack of systematic education in research and academic writing in postgraduate medical education and highlighted the need for nationally accessible education due to significant disparities in the educational environment across hospitals and specialties. The primary barrier to learning research and academic writing identified by learners was the lack of knowledge, leading to time constraints. Improving learners' research competencies, relationship building, autonomy, and motivation through a support system was deemed crucial. The study also identified diverse learner types and preferred educational topics, indicating a demand for learner-centered education and coaching. Conclusion: This study provides foundational data for designing and developing a program on education on research competencies for interns and residents in Korean medicine and suggests the need for initiatives to strengthen these competencies.

This paper examine how CCT affected to writing task performance and EEG through 24 elementary students from in July to September, 2014. The study analyzed EEG that was changed in a task performance under an orange color light and a white color light in a laboratory for stabilization and relaxation. The study results showed that an alpha wave, beta wave, high-beta wave were high under the white color light. The task performance time, however, showed significant fast performance under the orange color light. Although pre-existing low CCT has been considered as typical type for stabilization and relaxation, this study provides that the various applications in the elements of cognition, tasks, and types can affect improvement of task performance and occupation ability.

The online shopping environment has radically changed consumer shopping behavior. Without the actual physical shopping experience in a brick-and-mortar store, consumers make purchasing decisions over the Internet. They make an effort to obtain product information not only from online merchants, but also from previous purchasers in order to make an informed decision. Accordingly, customer comments are expected to have a significant impact on decisions to purchase goods and services online. This paper focuses on one type of electronic word-of-mouth, the online consumer review. It derives several motivations why customers post product reviews on shopping mall sites. Customer motives were identified through an in depth one-on-one interview with twenty female respondents conducted twice from June $17^{th}$ to September $11^{th}$, 2009. The interviews lasted between 40 and 60 minutes. The results showed that consumers write product reviews based on six motivations: to receive a reward or remuneration for writing a product review, to share information with other customers, to improve the quality of goods and services, to reduce customer dissatisfaction, to recommend products and services, and to derive pleasure.

Photopolymers are quite promising candidates for holographic data storage and diffusers because of their high sensitivity and high refractive index modulation. New photopolymers were prepared using the cellulose ester binder bearing different kinds of monomer. The holographic gratings were elaborated successfully in these photopolymer samples by conventional optical interference method. We investigated the dynamic behavior of the diffraction efficiency and the effect of the functionality of the monomer doped into the polymer binder. Triacrylate monomer doped photopolymer showed the highest diffraction efficiency of around 80-90 %, even under low intensity of writing beam (I=2 mW/$cm^2$). We inscribed the gratings of the glass diffuser on the surface of the photopolymer and investigated their diffusion properties.

This study was conducted to better understand the effect of the classroom literacy environment on the young children's vocabulary abilities, and the concepts of print matter. The subjects consisted of 276 children aged 3 to 5 enrolled in 93 classrooms in child-care centers and kindergartens. The Early Language & Literacy Classroom Observation Pre-K (Smith, Brady, & Anastasopoulos, 2008), the Picture Vocabulary Test (Kim, Jang, Yim, & Bae, 1995) and the Concepts About Print (Kim & Kim, 2004) were used for the purposes of this study. The data collected were analyzed by means of ANOVA, and regression analysis. The results indicated that the vocabulary abilities and print-concepts of children aged 3-5 were more likely to increase when a rich classroom environment was provided for the children's literacy development. In particular, it was found to be important for children's language and Literacy development to provide them with an enriched 'language environment' within the classroom, the quality of 'books and book reading', and the active utilization of 'print and early writing' all being important elements of this.

It becomes more and more more important for the storage that supports high speed recording and stable access from network environment. As one field of basic science which produces massive astronomical data, VLBI(: Very Long Baseline Interferometer) is now demanding more data writing performance and which is directly related to astronomical observation with high resolution and sensitivity. But most of existing storage are cloud model based for the high throughput of general IT, finance, and administrative service, and therefore it not the best choice for recording of big stream data. Therefore, in this study, we design storage system optimized for high performance of I/O and concurrency. To solve this problem, we implement packet read and writing module through the use of libpcap and pf_ring API on the multi core CPU environment, and build a scalable storage based on software RAID(: Redundant Array of Inexpensive Disks) for the efficient process of incoming data from external network.

The virtual Korean keyboard system is a method of inputting characters by touching a fixed position. This system is very inconvenient for people who have difficulty moving their fingers. To alleviate this problem, this paper proposes an efficient framework that enables keyboard input and handwriting through video and user motion obtained through the RGB camera of the mobile device. To develop this system, we use face recognition to calculate control coordinates from the input video, and develop an interface that can input and combine Hangul using this coordinate value. The control position calculated based on face recognition acts as a pointer to select and transfer the letters on the keyboard, and finally combines the transmitted letters to integrate them to perform the Hangul keyboard function. The result of this paper is an efficient writing system that utilizes face recognition technology, and using this system is expected to improve the communication and special education environment for people with physical disabilities as well as the general public.
