This study purposed to analyze difference in experience of life in Korea among adolescents whose immigrant backgrounds were different (Korean-born children of multicultural families and foreign-born immigrant children) using the data of the 2012 National Survey of Multicultural Families (adolescent children aged between 9 and 24). According to the results of analysis, first, multicultural adolescents with immigrant backgrounds experienced 'difficulty in using the Korean language (speaking, listening, reading, and writing),' 'school dropout,' and 'school violence' more frequently than Korean-born multicultural adolescents. Second, with regard to social discrimination (friends, teachers, relatives, neighbors, and unknown people), multicultural adolescents with immigrant backgrounds experienced 'discrimination by teachers,' 'discrimination by relatives,' 'discrimination by neighbors,' and 'discrimination by unknown people' more frequently than Korean-born multicultural adolescents. By analyzing these differences, this study suggested directions for differentiated support policies and specific strategies for adjustment to life in Korea by multicultural family adolescents with different backgrounds.

The study aims to gain information for developing educational contents to support LPSMB(low-performing students with multicultural backgrounds) through the survey on their personal characteristics, attitudes related to learning, and learning environment. We analyzed a survey of 2,091 students from 200 schools who were low-performing Korean students, LPSMBs, and normally performing students with multicultural backgrounds. Normally performing students with multicultural backgrounds showed statistically significant higher scores on most questionnaires than low-performing Korean students and LPSMBs. However, normally performing students with multicultural backgrounds and LPSMs showed statistically significant lower scores on identity and social relationships. LPSMBs showed lower scores on parents' culture than normally performing students with multicultural backgrounds. We suggested how to support LPSMBs' learning and learning environment based on the survey results.

As the online shopping mall market faces severe competition, marketers have focused on visual factors that generate positive consumer responses in order to induce more consumers. Although product photos are crucial in the communication of product information as well as in the development of positive images of online shopping mall, there was little intention the effect of diverse types of product photo. In this study, three types of backgrounds (i.e., no background, indoor background, street background) are compared in order to explore whether consumer sensibility factors are different according to photo backgrounds. Moreover, it investigates the effect of sensibility toward photo backgrounds on consumer attitude. A total of 222 consumers participated in the experiments. As a result, six sensibility factors were generated from online model photos, including structure, upscale, uniqueness, interest, simpleness, and easiness factors. Among these factors, simpleness and structure showed the highest means; simpleness was the factor indicating the differences according to photo backgrounds. Sensibility factors affecting attitude toward online shopping malls were uniqueness in the case of no background, interest in the case of indoor background, and upscale in the case of street background photo.

In laser pointer interaction systems, laser spot detection is one of the most important technologies, and most of the challenges in this area are related to the varying backgrounds, and the real-time performance of the interaction system. In this paper, we present a robust dictionary construction and update algorithm based on a sparse model of background subtraction. In order to control dynamic backgrounds, first, we determine whether there is a change in the backgrounds; if this is true, the new background can be directly added to the dictionary configurations; otherwise, we run an online cumulative average on the backgrounds to update the dictionary. The proposed dictionary construction and update algorithm for laser spot detection, is robust to the varying backgrounds and noises, and can be implemented in real time. A large number of experimental results have confirmed the superior performance of the proposed method in terms of the detection error and real-time implementation.

In recent times, STEM graduates are confronting a decline in employment rates influenced by economic, social, cultural, and policy-related factors. Career decisions are closely linked to education, college experiences, and university settings. To comprehend the reasons behind the decline in STEM employment, it is essential to explore the relationships among these factors. This study aims to comprehensively examine differences in career motivation and career exploration behavior among 2,393 STEM undergraduates in Korea. Additionally, factors affecting career motivation and career exploration behavior were investigated. The findings indicate significant differences in perceived career motivation and career exploration behavior based on individual backgrounds and university characteristics. And analyzing the data, 37.8% of career motivation is explained by contextual supports, career barriers, individual backgrounds (grade, GPA), university characteristics (major fields, location), field to enter after graduation, and timing of job preparation. For career exploration behavior, 30.1% is explained by contextual supports, career barriers, individual backgrounds (gender, grade, GPA), university characteristics (major field, location), field to enter after graduation, and timing of job preparation. Practical implications underscore the need for tailored educational and policy support, considering individual backgrounds and university characteristics, to effectively address challenges faced by STEM graduates in the evolving employment landscape.

The aims of this study were to evaluate the adequate thickness of opaque resins for situations such as an oral black cavity and discolored tooth structure, as well as the translucency of each opaque material at various thicknesses. Six opaque-shade composite resins (Z-350 OA3, Amelogen Universal A2O, Esthet-X A2O, Esthet-X A4O, Charmfil UO and Aelite Universal OA3) were prepared in metal molds with a hole of 8 mm in diameter and various thicknesses (0.5mm, 1.0mm, 1.5mm, 2.0mm, 2.5mm, 3.0 mm and 4.0mm). Four backgrounds (white tile, black tile, C4 shade porcelain and opaque resin itself) were used to determine the translucency parameter (between black and white backgrounds). and to mimic a black oral cavity (between black and opaque resin backgrounds) and a discolored tooth structure (between C4 and opaque resin backgrounds). Color measurements were made by a colorimeter to determine the CIELAB values of each specimen with each background and to calculate the translucency parameter and ${\Delta}E^*$ value difference among the specimens on the backgrounds. The translucency parameter and ${\Delta}E^*$ obtained between black and opaque resin backgrounds decreased in similar pattern as thickness increased. A C4 background was masked by resin thicknesses of 0.5-1.0mm, while a black background required thicknesses of 1.0-2.0mm. Adequate knowledge about differences in the optical character like translucency of the materials used is essential, together with the accumulated experience of the individual clinician.

A new method in thermal ionization mass spectrometry (TIMS) was developed to correct peak tailing backgrounds in the isotope ratio measurements of uranium in ultra trace levels for higher accuracy. Two different uranium standard reference materials (U005 and U030) were used to construct databases of signal intensities at mass 234 u and mass 236 u, which correspond to the two uranium minor isotopes, and signal intensity of $^{238}U$. Correlations between peak tailing backgrounds and $^{238}U$ were obtained by least-squares regression on calculated backgrounds at mass 234 u and mass 236 u with respect to the signal intensity of $^{238}U$ followed by separation of the peak tails of the two major isotopes of uranium ($^{235}U$ and $^{238}U$), which enables us to obtain a master equation for peak tailing background correction on all kinds of samples. Verification of the correction method was carried out using U010 and IRMM-040a.

We have studied experimentally the propagation characteristics of fundamental dark spatial solitons on finite-width backgrounds and conpared with the result of numerical simulations. It was verified experimentally that the width of dark solitons decreased but that of background increased as the beam intensity increased. The refractive index change obtained from soliton constant, which is for infinite-width background, was smaller than that from Z-scan method. Numerical simulations of fundamental dark solitons on a finite-width backgrounds showed that the peak intensity of background, the width of dark soliton and the soliton constant varied with the propagation length. If the change of soliton constant on finite-width backgrounds was considered, the refractive index change was in good agreement with that from Z-scan method. ethod.

As the use of cultural elements to enhance design has become increasingly emphasized, fashion studies are focusing more on the cultural aspects of design. However, the diverse approaches of Minhwa (Korean folk painting) still need to be incorporated into fashion designs. Moreover, there is limited research on the awareness and thought of using a cultural design source of Minhwa based on people from different cultural backgrounds. This study aims to reveal an in-depth understanding of the use of Minhwa and its inner symbolic meaning by people from a diverse range of cultural backgrounds. A review of the literature on cultural design and Minhwa studies was conducted to establish a theoretical foundation. Focus group interviews were conducted with 26 participants, who were divided into five distinct cultural groups to ascertain their thoughts towards Minhwa and its inner symbolic meaning. The study's major findings were threefold. First, the outer appearance of Minhwa elements based on aesthetic preferences and familiarity affect their preference choices more than the influences of their cultural backgrounds. Second, knowing the knowledge of symbolic meaning makes a big difference in image preference. Third, avoiding the use of anachronisms is a significant consideration, as they can lead to negative judgments irrespective of cultural background.

In this paper, we propose the visual tracking algorithm that takes advantage of multiple random walkers. We first show the tracking method based on support vector machine as [1] and suggest a method that suppresses feature vectors extracted from backgrounds while preserve features vectors from foregrounds. We also show how to discriminate between foregrounds and backgrounds. Learned by reducing influences of backgrounds, support vector machine can clearly distinguish foregrounds and backgrounds from the image whose target objects are similar to backgrounds and occluded by another object. Thus, the algorithm can track target objects well. Furthermore, we introduce a simple method improving tracking speed. Finally, experiments validate that proposed algorithm yield better performance than the state-of-the-art trackers on the widely-used benchmark dataset with high speed.
