Purpose: The study is to investigate the effect of communication and self-leadership on nursing performance. Methods: The subjects of study were composed of 358 nurses at a G city university hospital, tested with structured questionnaire from September 15 to 30, 2010. The collected data were analyzed with ANOVA, Pearson's correlation coefficients and multiple regression analysis. Results: The level of communication, self-leadership, and nursing performance was 3.37, 3.38 and 3.70 respectively in average. The variables showing significant difference in communication were as follows: age, marital status, religious status, education, monthly income, work department and work experience. Also, the variables in nursing performance were as follows: age, marital status, religious status, education, education, monthly income, position, working department and work experience. Communication, self-leadership and nursing performance of nurse showed significant positive correlation. Nursing performance was positively correlated with monthly income, when it exceeded 2.01 million won, career experience and self-leadership (p<.001). These variables explained 53.7% of the regression model. Conclusion: Since monthly income, work experience, communication and self-leadership have positive effect on nursing performance, an effective strategy is required to improve self-leadership and nurse's communication.

Chocolate milk is one of the most commonly used non-fermentative dairy products, which, due to high level of sucrose, could lead to diabetes and tooth decay among children. Therefore, it is important to replace sucrose with other types of sweeteners, especially, natural ones. In this research, response surface methodology (RSM) was used to optimize the ingredients formulation of prebiotic chocolate milk, date syrup as sweetener (4-10%w/w), inulin as prebiotic texturizer (0-0.5%w/w) and carrageenan as thickening agent (0-0.04%w/w) in the formulation of chocolate milk. The fitted models to predict the variables of selected responses such as pH, viscosity, total solid, sedimentation and overall acceptability of chocolate milk showed a high coefficient of determination. The independent effect of carrageenan was the most effective parameter which led to pH and sedimentation decrease but increased viscosity. Moreover, in most treatments, date syrup and inulin variables had significant effects which had a mutual impact. Optimization of the variables, based on the responses surface 3D plots showed that the sample containing 0.48% (w/w) of inulin, 0.04% (w/w) of carrageenan, and 10% of date syrup was selected as the optimum condition.

Purposes: Speech acceptability means the subjective judgement of listeners regarding the naturalness and normality of the speech. The purpose of this study was to determine the predicting variables for speech acceptabilities of children with cochlear implants. Methods: Twenty seven children with CI participated. They had profound pre-lingual hearing loss without any additional disabilities. The mean of chronological ages was 8;9, and mean of age of implantation was 2;11. Speech samples of reading and spontaneous speech were recorded separately. Twenty college students who were not familiar to the speech of deaf children evaluated the speech acceptabilities using visual analog scale. 1 segmental (articulation) and 6 suprasegmental features (pitch, loudness, quality, resonance, intonation, and speaking rate) of speech were perceptually evaluated by 3 SLPs. Correlation and multiple regression analysis were performed to evaluate the predicting variables. Results: The means of speech acceptability for reading and spontaneous speech were 73.47 and 71.96, respectively. Speech acceptability of reading was predicated by the severity of intonation and articulation. Speech acceptability of spontaneous speech was predicated by the severity of intonation and loudness. Discussion and conclusion: Severity of intonation was the most effective variable to predict the speech acceptabilities of both reading and spontaneous speech. A further study would be necessary to generalize the result and to apply this result to intervention in clinical settings.

The purpose of this study is to promote trade between Korea and South American countries. Korea's trade with South America has decreased recently. This study analyzed the effects of arbitration on trade between Korea and South America. To this end, we conducted an analysis of the gravity model of trade between Korea and South America. The gravity model is a research method that is widely used to analyze the pattern of international trade. The dependent variables of the gravity model were trade in Korea and South America. The independent variables were GDP, population, and distance between Korea and South America. In addition, dummy variables were the FTA and whether to join the New York Convention or Washington Convention. Joining either Convention indicated the establishment of an international arbitration system. As a result, an arbitration system appeared to be effective in increasing trade. Depending on the results it shows the importance of utilizing the system of arbitration in South America. So this study analyzed the current status of arbitration in South America. To companies doing business in South America it provided the implications for an arbitration system there. Also it proposed a method for increasing trade for the Korean government and institutions.

The availability and efficient use of the feed resources in India are the primary drivers to maximize productivity of Indian livestock. Feed security is vital to the livestock management, extent of use, conservation and productivity enhancement. Assessment and forecasting of livestock feed resources are most important for effective planning and policy making. In the present study, 40 years of data on crop production, land use pattern, rainfall, its deviation from normal, area under crop and yield of crop were collected and modeled to forecast the likely production of feed resources for the next 20 years. The higher order auto-regressive (AR) models were used to develop efficient forecasting models. Use of climatic variables (actual rainfall and its deviation from normal) in combination with non-climatic factors like area under each crop, yield of crop, lag period etc., increased the efficiency of forecasting models. From the best fitting models, the current total dry matter (DM) availability in India was estimated to be 510.6 million tonnes (mt) comprising of 47.2 mt from concentrates, 319.6 mt from crop residues and 143.8 mt from greens. The availability of DM from dry fodder, green fodder and concentrates is forecasted at 409.4, 135.6 and 61.2 mt, respectively, for 2030.

Predicting the quality of materials after they are subjected to plasma sintering is a challenging task because of the non-linear relationships between the process variables and mechanical properties. Furthermore, the variables governing the sintering process affect the microstructure and the mechanical properties of the final product. Therefore, an artificial neural network modeling was carried out to correlate the parameters of the spark plasma sintering process with the densification and hardness values of Ti-6Al-4V alloys dispersed with nano-sized TiN particles. The relative density (%), effective density (g/㎤), and hardness (HV) were estimated as functions of sintering temperature (℃), time (min), and composition (change in % TiN). A total of 20 datasets were collected from the open literature to develop the model. The high-level accuracy in model predictions (>80%) discloses the complex relationships among the sintering process variables, product quality, and mechanical performance. Further, the effect of sintering temperature, time, and TiN percentage on the density and hardness values were quantitatively estimated with the help of the developed model.

The purpose of this study was to identify the characteristics of coping behaviors of non-professional working mothers and find out the individual and situational factors which affect the degree of coping behaviors. For this research, the working mothers in non-professional job with children under age 18 answered the structured questionaire. The findings were as follows. First, the degree of coping behaviors was rather high in multiple role management strategies, strengthening family system and positive thinking, but rather low in housework socialization and role reduction/standard adjustment. Second, the effect of associated variables were different according to the subcategories of coping behaviors. So we conclude that, the coping behaviors of the non-professional working mothers were different from those of professional working mothers in some aspects, althought they have much similarities. The different aspects were 1) The relationship of family income and the degree of housework socialization was more evident. 2) The work-related variables did not affect the coping process significantly because of the conservative sex-role attitued of them. Second, non-professional working mothers should use coping behaviors such as housework socialization, role reduction/standard adjustment more for the more effective management of the role strain. Third, the attitude of occupational and parental role was one of the most important factors in using the role strain coping behaviors. And such an unconscious use of the coping behavior won't be helpful in the feeling of control over environment including role strain and active coping of working mothers.
