This study was attempted in order to measure the level of Korean people's social capital and their multicultural acceptance, and to explain the relationship between the sub-factors of social capital(trust, reciprocity, and participation) and the multicultural acceptance. Furthermore, this study aimed to examine the relative influence of the sub-factors of social capital on the multicultural acceptance and to suggest which social capitals should be reinforced. Data on 'social capital' and 'multicultural acceptance' used in this study were obtained from the data of the 8th Korean General Social Survey (KGSS) in 2010. The results of analyses are as follows. First, social capital was lower with increase in age (F=28.18, p<.001), and higher with increase in academic qualification (F=15.49, p<.001), and total household income (F=8.85, p<.001). Second, the multicultural acceptance was higher in men (t=9.98, p<01) and lower with increase in age (F=27.29, p<.001), and higher with increase in academic qualification (F=28.99, p<.001), and total household income (F=11.92, p<.001). Third, among the three social capital factors influencing the multicultural acceptance, 'trust' was found to have a significant positive (+) effect. Based on these results were suggested various strategies for enhancing Korean people's multicultural acceptance.

The purpose of this research was to develop and verify applicability of a musical play program aimed at promoting interaction between immigrant preschoolers and Korean preschoolers. A daycare center serving the preschool-age children of Korean nationals and immigrant families were the site for this research. Utilizing the elements of a musical play (e.g., role playing, narration, and joint music activity), the program was developed for improving interaction among preschoolers, while promoting intercultural acceptance by providing the opportunity to be exposed to music from different cultures and engage in the joint activity using such music. For the purpose of investigate the applicability of the developed program, the program was implemented with two groups of preschoolers and each group received the musical play program for 30 minutes twice a week for a total of 6 sessions. The results of this preliminary study indicate that the musical play program promoted interaction between peers from different cultural background. Based on the results of this study, musical play programs may be helpful in promoting interactions between preschoolers from different cultural backgrounds and increase of acceptance of immigrant students in Korean daycares and schools.

Most of studies for the ground load and ground behavior of landing gear have been conducted with an assumption that the structure of landing gear was rigid body. The assumption of rigid body during design process results in many errors or discrepancy. High ground load occurs in 3 directions on the shock absorbing strut during landing. This ground load initiated high structural deformation. In this study, the flex-multi-body dynamics is applied to adapt flexible bodies, so the results of analysis can be described close to landing gears real behaviour.

In this paper, performance of an orthogonal frequency division multiplexing (OFDM) system in an impulsive noise environment is analyzed. Here, it is verified that performance of the OFDM system with window nonlinearity, which is one of the impulsive noise mitigation algorithms, is dependent on the over-sampling rate and the size of window. With respect to the variation of those parameters, we also provide an appropriate region of threshold values that control amplitudes of the sampled waveform of received signals. As a result, a new combination of parameters which improves error performance of OFDM system in an impulsive noise environment as compared to the previously reported parameters is presented.

오늘날 영어교육은 교과과정령에 엄연히 명시된 네 가지 기능(four skills) 즉 듣기, 말하기, 원기, 쓰기라는 정당하고도 보편 타당성 있는 명분 하에 어떻게 가르쳐 왔는가 를 반문해 보면 많은 아쉬움이 남는다. 그간 6년간의 중등과정, 심지어는 대학에서 환 두해까지 영어를 이수한 사람틀 중에는 문자를 통해서는 상당한 수준, 그것도 영어 토박이들조차 놀랄 정도의 영어를 이해하지만, 소리를 통해 들을 때는 ---말하는 것은 두말 할 것도 없고---아주 간단한 내용의 영어조차 알아듣기 힘든 경험을 한 사람이 많다는 것은 부인할 수 없는 사실이다. 그 이유는 명백하다. 즉, 문자를 대할 때는 시각적 자극의 형태가 두뇌 속에 저장된 정보---가공할 문법적 지식---와 일치하기 때문에 쉽게 이해를 할 수 있는 반면, 소리를 들을 때는 청각적 자극의 형태가 두뇌 속에 저장된 정보---극히 불완전한 발음사전, 또는 모국어의 음운체계에 의한 영어발음--- 와 차이가 있기 때문일 것이다. 그러므로 적어도 말소리를 매체로 하는 의사소통에 있어서는 영어의 본토박이 발음을 정확히, 아니면 적어도 매우 근접하게 나마 터득하여(습관화하여)두뇌에 저장하는 일이 가장 중요한 일이다. 따라서 영어교사는 모국어의 음운체계에 대한 정확하고도 상세한 지식을 토대로 하여 영어의 음운체계와 '언어학적으로 의미 있는 (linguistically significant)' 대초분석의 방법으로 발음을 지도한다면 보다 나은 학습효과를 기대할 수 있을 것이다. 일반적으로 모국어의 발음이 외국어의 발음에 간섭을 유발하는 경우는 다음과 같다. 1. 분절음체계가 서로 다를 때 2. 한 언어의 음소가 다른 언어의 이음(allophone)일 때 3. 유사한 음의 조음장소와 방법 이 다를 때 4. 분절음의 분포 또는 배열이 다를 때 5. 음운현상이 다를 때 6. 언어의 리듬이 다를 때 위의 여섯 가지 경우를 중심으로 영어와 한국어의 발음특성을 대조하여 '낯선 말투(foreign accent)' 또는 발음오류를 최소로 줄이는 것이 영어교사의 일차적인 목표이다.

Most recent E-mail systems, that are serviced in Korea, are supporting Hangul in many fields of E-mail(For example, contents, subject, attachment, etc.). However, these systems do not support Hangul in the address field of E-mail. In 2003, IDNA built the international standard in order to support multi-lingual besides the alphabetic character, a number, and '-'. So, Hangul cab be used in the domain part where is the right of '@' mark among the compositional element of the E-mail address. But, the local-part, where is the left of '@' mark, doesn't still support multi-lingual. So Hangul cannot be used in the local-part. In order to support multi-lingual including Hangul in the local-part, this paper designs and implements the E-mail system according to the EAI standardization research that it is progressed in IETF.

So far, most of research activities on modeling of membrane separation processes have been focused on binary feed mixture. But, in actual separation operations, binary feed is hard to find and most separation processes involve multicomponent feed mixture. In this work models for membrane separation processes treating multicomponent feed mixture are developed. Various model types are investigated and validity of proposed models are analysed based on experimental data obtained using hollowfiber membranes. The proposed separation models show quick convergence and exhibit good tracking performance.

The purpose of this study is to understand school dropout experiences of multiculrual adolescents and to suggest policy of promoting their school adjustment. In-depth interviews are conducted with four multicultural adolescents who have dropped out from school and the interviews were analyzed using the phenomenological analysis method. The current study finds that school dropout experiences of multicultual adolescents could be classified in seven themes and those themes are divided again into 19 sub-themes. The seven main themes are as follows: 'the family in crisis', 'maladjustment in school life', 'discrimination and conflict', 'school-violence victimization', 'school dropout crisis', 'nonoperating the mandatory delay before school dropout program', and 'school dropout'. Based on these results, we would like to provide basic information to prevent multicultural youth's academic suspension.

Comosomal polymorphism involving constitutive heterochromatin has been reported in mu, pigs, mouse, horse, chicken and so on. The chromosomal polymorphism of Japanese quail which includes constitutive heterochromatin as well the chromosomes without banding treatment has now been found. Through the use of a general technique that permits visualization of chromosome morphology and heterochromatin, three chromosomal variants have been found among birds ； ＋/＋ homozygous from, ＋/－ heterozygous form and －/－ homozygous form in chromosome 4. This variants appear to be common in the randombred population and stably inherited in a Mendelian fashion. These results suggest that the variants would be useful as chromosomal markers for various types of cytogenetic studies.

The use of Multiparty Conference service based on SIP for VoIP provides is gradually magnified, and the work for continuous development and standardization on SIP is in the process of advancing. But, currently it is impossible for SIP to support identity discovery and distribution of each participant for multiparty conference. In this paper, we propose a SIP extension for guaranteeing security on the multiparty conference using SIP by adding new method and reconstructing header informations. With this, it is also possible to identify discovery and to distribute each participant using SIP extension when a call is established for closed multiparty conference.
