A communication approach to the acculturation process: A study of Korean immigrants in Chicago     

Young Yun Kim 《Int J Intercult Relat》1978,2(2):197-224

This paper explores a theoretical and methodological basis for studying foreign immigrants' acculturation processes from a communication perspective. Communication patterns of immigrants are conceptualized on three levels — behavioral, attitudinal, and perceptual. The behavioral level of communication includes the immigrant's participation in communication channels of the host society as well as the ethnic community. The perceptual level refers to the immigrant's cognitive structure in perceiving the host society. The attitudinal level is examined by the immigrant's affective-evaluative orientation toward the host society. The three levels of communication patterns were empirically investigated in a survey of 400 randomly selected Koreans in the Chicago area. The communication variables were assessed through composite scores using questionnaire items that were tested for reliability. The results show an overall linear trend in the immigrant's interethnic communication with Americans, positive attitude toward Americans, cognitive complexity in perceiving the American society, and satisfaction level. A simultaneous increase is observed in the immigrant's interpersonal communication with Americans and with other Koreans. The immigrant's use of ethnic media rapidly decreases over the years while that of American media steadily increases. Findings are discussed in comparison to previous studies of foreign immigrants and students and to sociological theories of acculturation of minority groups.  相似文献

Gravity-oriented microfluidic device for uniform and massive cell spheroid formation     

Lee K  Kim C  Young Yang J  Lee H  Ahn B  Xu L  Yoon Kang J  Oh KW 《Biomicrofluidics》2012,6(1):14114-141147

We propose a simple method for forming massive and uniform three-dimensional (3-D) cell spheroids in a multi-level structured microfluidic device by gravitational force. The concept of orienting the device vertically has allowed spheroid formation, long-term perfusion, and retrieval of the cultured spheroids by user-friendly standard pipetting. We have successfully formed, perfused, and retrieved uniform, size-controllable, well-conditioned spheroids of human embryonic kidney 293 cells (HEK 293) in the gravity-oriented microfluidic device. We expect the proposed method will be a useful tool to study in-vitro 3-D cell models for the proliferation, differentiation, and metabolism of embryoid bodies or tumours.  相似文献   

Distributed fusion receding horizon filtering for uncertain linear stochastic systems with time-delay sensors     

Il Young Song  Vladimir Shin  Moongu Jeon 《Journal of The Franklin Institute》2012,349(3):928-946

A new distributed fusion receding horizon filtering problem is investigated for uncertain linear stochastic systems with time-delay sensors. First, we construct a local receding horizon Kalman filter having time delays (LRHKFTDs) in both the system and measurement models. The key technique is the derivation of recursive error cross-covariance equations between LRHKFTDs in order to compute the optimal matrix fusion weights. It is the first time to present distributed fusion receding horizon filter for linear discrete-time systems with delayed sensors. It has a parallel structure that enables processing of multisensory time-delay measurements, so the calculation burden can be reduced and it is more reliable than the centralized version if some sensors turn faulty. Simulations for a multiple time-delays system show the effectiveness of the proposed filter in comparison with centralized receding horizon filter and non-receding versions.  相似文献   

Congenital atresia of the left main coronary artery in an infant     

Su Ye Sohn  Gi Young Jang  Byung Min Choi 《Journal of Zhejiang University. Science. B》2010,11(7):539-541

Congenital atresia of the left main coronary artery is a rare occurrence, and surgical revascularizationbypass graft is required. We here report a rare case of congenital coronary anomaly in an infant. A 10-month-old male infant was admitted to the hospital with heart failure symptoms. Echocardiographic examinations revealed mitral valve regurgitation and ischemic changes of the anterolateral papillary muscle and chordae. Coronary angiography showed atresia of the left main coronary artery with a severe hypoplastic left anterior descending artery and a circumflex coronary artery. Unfortunately, sudden cardiac arrest occurred after catheterization and the infant did not recover despite of immediate cardiopulmonary resuscitation. Further studies are needed to find a newer diagnostic method to detect coronary anomaly in an infant, and coronary angiography, if necessary, has to be performed very carefully.  相似文献
