This study was conducted to investigate the cultural sensitivity and stereotype about immigrant women among nursing students. The participants in this study were 144 nursing students Data were collected from May to June 2013. The mean age of subjects was 21.8 years old. 68.1% of subjects had have experiences to travel abroad. Many subjects(90.3%) reported that multi-cultural education was needed. 66.0% of subjects met foreigners at clinical place among practice period. The cultural sensitivity and stereotype were middle range. It suggested that to prepare for the coming era of globalization, and to increase the nursing students' cultural sensitivity, a transcultural nursing curriculum needs to develop for appropriate and effective services in cross-cultural situations of the multicultural families in Korea.

The endpoints and exchanges involved in a call can establish heterogeneous connection each other according to required bandwidth and bearer availability in multimedia communication. and as participating users are increased, call setup delay must not be exceedingly increased. In this paepr, we propose DMMSP(distributed multiparty multiconnection signaling protocol) which can support heterogeneous connections and multimedia communications. DMMSP gets over a limitation of existing B-ISDN protocol and provides signaling capabilities to support various kinds of conncetions, and each endpint can setup individual connection with bearer availability. Moreover since DMMSP separatively performs call processing in distributed scheme, call setup delay can be minimized. We present call control procedures which can be applied to existing B-ISDN protocol and DMMSP respectively. We take multiparty multimedia conference call as an example thta is applied to the existing B-ISDN protocol and DMMSP, and compare and quantitatively analyze each procedures.

In exopolysaccharide fermentation by Aureobasidium pulluans, the effects culture conditions (concentration of nitrogen, potassium phosphate, dissolved oxygen, and initial pH) on the production of exopolysaccharide and the appearance of melanin pigment were investigated. The results are as follows. (1) The specific growth rate and the specific production rate of exopolysaccharide were inhibited by substrate when the carbon source concentration higher than $50g\;/\;{\ell}$ and the cell growth increased with increases of nitrogen source but exopolysaccharide production decreased with the nitrogen concentration when it become greater than $1\;g\;/\;{\ell}$. (2) The maximum cell growth and the maximum exopolysaccharide production were obtained at initial pH values of 3.0 and 7.5 respectively. As the initial pH increased, the yeast-like cells increased and the increased of dissolved oxygen increased the cell growth and exopolysaccharide production. (3) As the concentration of dissolved oxygen is increased or the concentration of nitrogen source is decreased, the period of melanin pigment appearance becomes shorter and the melanin pigment never appeared when the initial pH was less than 3.0 or the potassium phosphate was not added.

This study aims to testify the effect of reading and writing abilities improvement program for elementary school children from multicultural families. Methods: The research design used in this study was a non-equivalent control group pretest-posttest research design. The participants were divided into two groups, an experimental group(n=9) and a control group(n=8). Data were analysed by using Mann-Whinety U test, Wilcoxon Signed Ranks, Cohen's d with SPSS(PASW)18.0 program. Result: Significant differences were found in scores for reading ability (z=-2.668, p=.008, ES(d)=0.6) and writing ability (z=-2.670, p=.008, ES(d)=0.5) in experimental group. Conclusion: The results indicate that the reading and writing abilities improvement program should be used with elementary school children of multicultural families to help them and to improve their reading and writing abilities.

Most fluid machines can be considered as periodic noise sources when operated under constant conditions, which allows for a frequency domain representation of the source and the associated acoustic field In the duct. In such a representation, the source is characterized by frequency-dependent values of both strength and impedance. Although knowledge of these values can be gained by either experimentation or by modeling, one-port acoustic characteristics of an in-duct source with high flow velocity, high temperature, and high sound level can be measured only by the multiload method using an overdetermined set of open pipes with different lengths as applied loads. However, the problem is that negative source resistances have been often measured. This paper reviews the possible causes of the problem, with reference to experimental and theoretical results, in an attempt to clarify the issue. A new interpretation is given for the violation of basic assumptions and the defect in the algorithm of multiload method. The major cause and mechanism of the problem is due to the violation of time invariance assumption of the source and the load impedance can seriously affect the final measured result of source impedance.

Dharavi, located in Mumbai, India, is the largest slum in the world, with over 700,000 people living in one area. The provincial government has selected a private business, and planning to promote Dharavi's redevelopment together. In addition, the Indian government announced three city development initiatives in 2015 and is promoting altogether the nationwide urban development in India, redevelopment projects in existing cities, and housing provision for slum residents. Through incorporating ongoing projects such as DMIC industrial corridor and smart city construction in India to the pharmaceutical industry that India has a comparative advantage over other industries, urban pharmaceutical research & production facility and residential complex is proposed in this paper, to be capable of supplying all occupants in the designated site, as a prototype for possible redevelopment directions.

This study was to investigate the relationship among emotional intelligence, social support and parent-child communication of multicultural primary school students in rural areas. All of the students for the study were sampled from three multicultural primary schools in rural areas. About 10% among them were from multicultural family students. First, the result indicated that students' emotional intelligence was positively correlated with social support and open communication with their parents. Second, there were no significant differences between unicultural family and multicultural family in social support, parent-child communication, and emotional intelligence. Third, the result of regression analysis revealed that peer and family support were predictors of emotional intelligence of multicultural primary school students in rural areas. The implications for the improvement strategy for multicultural primary school in rural ares were suggested.

Looking at the recent value change of users and the usage pattern of network users, it is changing from simple web information, one-way information acquisition and data transmission to increase of usage of multimedia, increasing demand for security and customization, and increasing demands for free mobility. Due to this change of demand, the services which were provided individually, developed into a form which is merged, the network also seems to develop into the combined network from the individual network for individual service, and the communication network control technology which is the core technology is also rapidly developing. To reflect the users' demands, the next generation network created the multi-layer network which is based on the WDM/IP transmission system and added the to make it easy to restructure. P-OTS (Packet-Optical Transport System) can be defined as a platform that combines SONET/SDH, Ethernet, DWDM, optical transport network (OTN) switching and reconfigurable optical add-drop multiplexers (ROADMs). In this paper, we suggested that the optimum path choice be performed through diversification of the PCE-based path selection using the information of various layers altogether in the multi-layer environment, compared with the established path selection method when the path was selected using the information of each layers.

This paper describes multiparticle finite element model (MPFEM)-based powder compaction simulations performed to demonstrate the densification of compacted aluminum powders. A 2D MPFEM was used to explore the densification of a collection of aluminum particles with different average particle sizes under various ram speeds. Individual particles are discretized using a finite element mesh for a detailed description of contact mechanics. Porous aluminum powders with average particle sizes of $20\;{\mu}m$ and $3\;{\mu}m$ were compressed uniaxially at ram speeds of 5, 15, 30, and 60 mm/min by using an MTS servo-hydraulic tester. The slow ram speed was of great advantage to powder densification in low compaction force due to sufficient particle rearrangement. Owing to a decrease in the average particle size of aluminum, the compaction force increased.

This paper descbibes a fuzzy multiobjective linear programming, which is a relatively new approach in forestry in solving forest management problems. At first, the fuzzy set theory is explained briefly and the fuzzy linear programming(FLP) and the fuzzy multiobjective linear programming(FMLP) are introduced conceptionally. With the information obtained from the study area in Thailand, a standard linear programming problem is formulated, and optimal solutions (present net worth) are calculated for four groups of timber price by this LP model, respectively. This LP model is reformulated to a fuzzy multiobjective linear programming model to accommodate uncertain timber values and with this FMLP model a compromise solution is attained. Optimal solutions of four objective functions for four timber price groups and the compromise solution are compared and discussed.
