Globalisation has intensified the international movement of labour and South Korea is no exception. Korea, which in the past was itself a labour-exporting country, has seen a reversal in human mobility since the late 1990's with a rapid growth in immigration and a transformation of a previously almost ethnically homogenous society. In this context, the important questions about the cultural and political implications associated with the construction of minority representations in the media have remained highly unexplored. The starting point of this study is an examination of the vital role of public service broadcasting (PSB) in Korean society, where ethnic minorities have increasingly become visible. The study shows the significant role of PSB in representing cultural diversity in public debates and the ways in which such representations and their dissemination reflect media power.

The purpose of this study was to identify caregivers of the elderly, the pattern of the caregivers' caring behaviors, and the cultural principles of patterns of caring behaviors practiced in a Korean minority community, Yanbian. To clarify these, an ethnographic approach was used. The fieldwork for this study was conducted from Aug. 24, 1993 to May 20, 1994. The informants were 16 natives, age 60 or more, who were members of a large family of three generations. The results of the study are as follows. The caregivers for the elderly were family, kinship and community groups. Family caregivers for the elderly were spouses, sons, daughters-in-law, grandchildren, sons of former wives, sons of former husbands, adopted sons. daughters and sons-in-law. The elderly had caregivers who were part of the kinship group. Three community groups provided care for the elderly. The three community groups were Dokbozo. a formal large organization for the elderly. the same age group as an informal small meeting for the elderly, and other community younger groups. The findings of this study indicated that family caregivers, especially spouses and sons, are the significant others of the elderly, and comminuty groups are better caring groups than kinship relatives. This study identified forty-three different kind of caring behaviors. They were divided into fifteen behavior patterns. These patterns integrated into five categories : soo-bal(¼?¹ß), protecting, respect, support, jung(?×). For physical comfort, soo-bal and protecting were conducted. For the comfort of mind, respect. support, and jung were conducted. The comfort of mind are better than physical comfort for the elderly. Cultural principles of caring behaviors were group membership, reciprocity, and harmony. But there was no hierarchy priciple. And these three principles provide best caring together at the same time. This study provides significant data for nursing research, theory and practice.

Half-metallic Heusler alloys (NiMnSb, ppdMnSb, pptMnSb) have attracted much attention due to their unique electronic and magnetic structures. Sppin-ppolarized band structure calculation ppredicts metallic behavior for the majority sppin states and semiconductor behavior for the minority sppin states. We have studied the electronic structures of these half-metallic Heusler alloys by core-level pphotoemission sppectroscoppy of Mn 2pp and 3s XppS sppectra. We found large intensities of Mn 2pp satellites and 3s exchange spplitting comppared with other metal Mn-alloys. These satellite structure can be understood by applying Anderson imppurity model. This fact supports the calculated sppin pprojected ppartial density of states which suggests that the valence electrons be highly sppin ppolarized near Fermi level and that the electrons involved with charge-transfer be mainly minority sppin ones which have semiconducting band structure. The trend of charge transfer energies Δ from ligands (Sb 5pp) to Mn 3d, obtained from our model fitting, is consistent with that calculated from sppin pprojected ppartial density of state. Also the trend of d-d electron correlation energies U calculated from Mn Auger line L3 VV by Mg $K\alpha$ source is comppatible with that resulted from our model fitting. We fitted the Mn 3s curve in the same way as for insulating Mn comppounds by using the same pparameters calculated from Mn 2pp curve fitting exceppt for the Coulomb interaction energy Q between core hole and d-electrons. The 3s sppectra were analyzed by combing the charge transfer model and a simpple model taking into account the configuration mixing effect due to the intra-shell correlation. We found that the exchange interaction between 3s hole and 3d electrons is mainly respponsible for the satellite of Mn 3s sppectra. This is consistent with the neutron scattering data, which suggests local 3d magnetic moment. We find that the XppS analysis results of Mn 2pp and 3s satellite structures of half-metallic Heusler alloys are very similar to those of insulating transition metal comppounds.

배경 및 목적: 성병 감염, 조기 성경험, 다수의 성관계 파트너 등과 같은 위험 성행동은 여성의 건강 전반을 위협하는 결과를 초래할 수 있다. 하지만, 이러한 심각성에 비하여, 미국의 청소년기 및 청년기 여성의 위험 성행동을 소수인종 집단별 특성을 고려한 연구는 부족한 실정이다. 그러므로 본 연구는 미국 소수인종 여성 청소년의 위험 성행동에 대한 실태를 조사하고자 한다. 방법: 본 연구는 2차 자료 분석의 결과물로써, 원자료인 미국의 National Longitudinal Study of Adolescent Health (Add Health)의 1기 (1995년)와 3기 (2001년)의 자료 중 여성 청소년의 자료를 바탕으로 분석되었다. 다양한 위험 성행동을 인종별로 분석함과 더불어 본 연구의 특징은 종단적 성병 감염 행태를 인종별로 분석한 점이다. 결과: 본 연구는 소수인종 여성의 위험 성행동에 관한 핵심적인 결과를 제시한다. 성병 감염, 조기 성경험, 다수의 성관계 파트너 등과 같은 위험 성행동의 분포는 흑인과 아시아계 여성이 타인종의 여성에 비하여 높은 위험해 쳐해 있는 것으로 나타났다. 본 연구의 흑인 여성들은 전반적인 성행동을 망라하여 고위험군으로 분류되고 있다. 아시아계 여성 역시 고위험 군으로 분류되는데, 특히, 청소년기에 성병에 한번 감염된 경험이 있는 아시아계 여성은 가장 위험한 성병 감염 행태를 보이고 있는 것으로 나타났다. 결론: 본 연구의 결과는 소수인종 여성의 위험 성행동이 백인보다 전반적으로 높은 편으로 나타나지만, 적절한 보건의료 서비스에서는 소외되는 현실을 지적하고 있다. 이러한 인종별 성건강의 불균형 문제해소를 위하여 청소년들에게 인종적 특성과 서비스 접근성의 고려가 절실히 필요하다고 사료된다.

Poly-Si wafers with resistivity of 1 [${\Omega}$-cm[ and thickness of 50 [${\mu}m$] were used as a starting material. Various efficiency influencing parameters such as rear surface recombination velocity and minority carrier diffusion length in the base region, front surface recombination velocity, junction depth and doping concentration in the Emitter layer, BSF thickness and doping concentration were investigated. Optimized cell parameters were given as rear surface recombination of 1000 [cm/sec], minority carrier diffusion length in the base region 50 [${\mu}m$], front surface recombination velocity 100 [cm/sec], sheet resistivity of emitter layer 100 [${\Omega}/{\Box}$], BSF thickness 0.5 [${\mu}m$], doping concentration $5{\times}10^{19}\;cm^{-3}$. Among the investigated variables, we learn that a diffusion length of base layer acts as a key factor to achieve conversion efficiency higher than 19.8 %. Further details of simulation parameters and their effects to cell characteristics are discussed in this paper.

It has been widely believed that the ethnic relations in Honolulu and Hawai'i in the early twentieth century were little associated with racist ideology because the white race was minority in terms of the racial composition. In reality, however, the racial and ethnic issues have played a major role in forming the past and present relations among ethnic groups. This study shows that the white-supremacy ideology exerted a strong influence on minority groups in Honolulu throughout the immigration and settling-down process, as much as in the mainland U.S. Clear occupational stratification and residential segregation among the ethnic groups in Honolulu represented almost the same situation as in mainland cities. The social segregation and spatial propinquity of their residential neighborhoods facilitated the construction of dichotomized identity: "Local" versus "Haole". Such transformed identities were a product of on-going inter-ethnic negotiation process embedded in the non-white multi-ethnic neighborhoods.

Poly-Si TFTs(polycrystalline silicon thin film transistors) fabricated on a low cost glass substrate have attracted a considerable amount of attention for pixel elements and peripheral driving circuits in AMLCS(active matrix liquid crystal display). In order to apply poly-Si TFTs for high resolution AMLCD, a high operating frequency and reliable circuit performances are desired. A new poly-Si TFT with CLBT(counter doped lateral body terminal) is proposed and fabricated to suppress kink effects and to improve the device stability. And this proposed device with BC(buried channel) is fabricated to increase ON-current and operating frequency. Although the troublesome LDD structure is not used in the proposed device, a low OFF-current is successfully obtained by removing the minority carrier through the CLBT. We have measured the dynamic properties of the poly-Si TFT device and its circuit. The reliability of the TFTs and their circuits after AC stress are also discussed in our paper. Our experimental results show that the BC enables the device to have high mobility and switching frequency (33MHz at $V_{DD}$ = 15 V). The minority carrier elimination of the CLBT suppresses kink effects and makes for superb dynamic reliability of the CMOS circuit. We have analyzed the mechanism in order to see why the ring oscillators do not operate by analyzing AC stressed device characteristics.

The purpose of this study is to explore the way that power in cyberspace is constructed and work and the factors that contribute to forming the power by analyzing a bulletin board system(BBS) on an everyday drama, "Can't Take My Eye Off You"(MBC). Research findings are as follows. The participants in the BBS produce various discourses and constantly compete with each other. In the process, the participants who produce a dominant discourse in quantity tend to exclude other discourses from the BBS and the participants who produce the minority discourses sometimes resist the dominant discourse but tend to refrain from expressing the minority discourses. These tendencies have intensified, and eventually the dominant discourse overwhelmingly powers over the BBS at the end of it. The dominant discourse in the BBS is confucian patriarchal one and this is primarily due to the characteristic of the BBS as the fandom of the drama, the participants' experience and dominant culture in their embodied social world, and the authorship of the drama.

We investigated the influence of blistering on $Al_2O_3$/SiON stacks and $Al_2O_3$/SiNx:H stacks passivation layers. $Al_2O_3$ film provides outstanding Si surface passivation quality. $Al_2O_3$ film as the rear passivation layer of a p-type Si solar cell is usually stacked with a capping layer, such as $SiO_2$, SiNx, and SiON films. These capping layers protect the thin $Al_2O_3$ layer from an Al electrode during the annealing process. We compared $Al_2O_3$/SiON stacks and $Al_2O_3$/SiNx:H stacks through surface morphology and minority carrier lifetime after annealing processes at $450^{\circ}C$ and $850^{\circ}C$. As a result, the $Al_2O_3$/SiON stacks were observed to produce less blister phenomenon than $Al_2O_3$/SiNx:H stacks. This can be explained by the differences in the H species content. In the process of depositing SiNx film, the rich H species in $NH_3$ source are diffused to the $Al_2O_3$ film. On the other hand, less hydrogen diffusion occurs in SiON film as it contains less H species than SiNx film. This blister phenomenon leads to an increase insurface defect density. Consequently, the $Al_2O_3$/SiON stacks had a higher minority carrier lifetime than the $Al_2O_3$/SiNx:H stacks.

Background: Breast cancer incidence is increasing among South Asian migrants to the United States (US). However, their utilization of cancer screening services is poor. This study characterizes attitudes of South Asians towards breast health and screening in a community sample. Materials and Methods: A cross-sectional survey based on the Health Belief Model (HBM) was conducted among South Asians (n=124) in New Jersey and Chicago. The following beliefs and attitudes towards breast cancer screening were assessed-health motivation, breast self-examination confidence, breast cancer susceptibility and fear, and mammogram benefits and barriers. Descriptive statistics and Spearman rank correlation coefficients were computed for HBM subscales. Findings: Mean age of participants was 36 years with an average 10 years stay in the US. Most women strived to care for their health ($3.82{\pm}1.18$) and perceived high benefits of screening mammography ($3.94{\pm}0.95$). However, they perceived lower susceptibility to breast cancer in the future ($2.30{\pm}0.94$). Conclusions: Increasing awareness of breast cancer risk for South Asian women may have a beneficial effect on cancer incidence because of their positive attitudes towards health and breast cancer screening. This is especially relevant because South Asians now constitute one of the largest minority populations in the US and their incidence of breast cancer is steadily increasing.
