  • Poultry feeding systems are likely to change for increased efficiency of production. An experiment was conducted to compare the response of broilers to choice feeding of corn with a standard broiler ration. The treatments consisted of providing broiler feed as the only feed (SINGLE FEED) and access to corn as a choice to a complete broiler feed (CHOICE FEEDING). Weights and feed consumption were obtained at weekly intervals. Samples at the conclusion of the experiment were taken to determine the weight of abdominal fat. Results showed that there was no significant difference in term of liveweight between the two feeding regimes. However, birds given a choice of the broiler feed and corn had better feed efficiency which is reflected by the lower total feed intake. Corn intake was 23.1% of total feed intake in the choice fed birds. In term of carcass colour, birds fed corn as a choice was observed to have a deeper yellow skin colour than the birds fed with broiler feed only.

  • The purpose of this study is to understand the elements of the standard of living aspired by today's Korean consumers with the consumer choice theory of the institutional school. This study attempted a qualitative method that is narration to collect live stories from 12 narrators. The results of this study indicated that Korean consumers eagerly aspired socially oriented standard of living which is farely materially oriented and mainly composed of a fixed list of famous brands. The physiological and welfare elements of the standard of living were not expressed in 12 narrators' stories. The personal and individual elements were also expressed within a limited extend. These results imply that the neoclassical theory of consumer choice is not appropiate for consumers in culture of collectivism.

  • American Society for Testing and Materials (ASTM) standard test method PS 070-97 has been created for measuring fracture toughness of advanced ceramics. PS 070-97 includes three test methods which use beams in bending: chevron notch (CNB), single-edged precracked beam (SEPB), and surface crack in flexure (SCF). Supporting data has been collected through several Versailles Advanced Materials and Standards round robins. This paper discusses the evolution of the standard including the rationale for the choice of the three methods and the specifications in the standard. Progress on Standard Reference material 2100 which will have certified values of fracture toughness is presented.

  • The purpose of this study were the effects of principal related factors on the choice of the subject of environmental education in curriculum of middle and high school. We select 495 middle and high schools from 3 district of Chungbuk, Daejeon and Incheon. And, we send the questionnaires to the principals and withrowed answer questionnaire of 313(63.2%) from them. From the analysis of questionnaire, we obtained the reliability coefficient cronbach alpha value(0.8684). The results of this research as fallows : the principal factors that had chosen the subject of environmental education have significantly higher knowledge, recognition, attitude and practice than that not choiced on the subject of environmental education(p=0.000). The correlation between principal's attitude on the choice of the subject of environmental education and choice state of school was significantly higher than the other factors, and it's correlation coefficient was 0.328(p<0.01). Principal's attitude factor on the choice of the subject of environmental education have a great influence on his practice factor of them, and standard regression coefficient was 0.642(p<0.001). We found that principal's attitude factor on the choice of the subject of environmental education to have a great influence on the choice state of school in view of the results so far achieved.

  • In mode choice decision, travelers consider not only travel time but also reliability of its modes. In this paper, reliability was expressed in terms of standard deviation and maximum delay that were measured based on triangular distribution. In order to estimate value of time and value of reliability, the Multinomial and Nested Logit models were used. The analysis results revealed that reliability is an important factor affecting mode choice decisions. Elasticity is used to estimate the impacts of the different policies and system improvements for water transportation mode. Among these policies, decision maker can assess and select the best alternative by doing the benefit and cost analysis based on a new market share, the value of time, and the value of reliability. Finally, a set of promising policies and system improvement of the water transportation were proposed.

  • The purpose of this study is to research space recognition change of the high school students according to geographic information quantities, focused on Factors Influencing the Land Value. The region of case study was some places of Songtan Special Tourism Zone, which responding students were unfamiliar with. The results are as follows. First, through the results of analysing 'the highest valued standard land and choice reasons' in two ㄴregions of the old town and the new town, it is perceived that the relative factor of land is more important than the absolute factor as the factors influencing the land value of the highest valued standard land. Second, there are students' recognition differences in the choice reasons of the highest valued standard land of two regions which have different characteristics. Third, though in the same region, recognitions about factors influencing the land value change according to geographic information quantities, and as students' knowledge about geographic information increases, the choice rate of the highest valued standard land increases. Lastly, it is perceived that there is a facility which has a decisive effect on formating the land value of a certain region.

  • Purpose: The purpose of the study was to evaluate career choice of male nursing students and identify factors influencing their career choice. Methods: Subjects were 123 male nursing junior and senior students in B city, U city, and GN area. Career types were classified into a hospital nurse and a community nurse. Subjects were asked about 29 items of nurse image and 31 items of satisfaction on clinical practice. The collected data were analyzed by frequency, percentage, average and standard deviation, t-test, ${\chi}^2$-test, and logistic regression, using SPSS 21.0 program. Results: The percentage of career choice which subjects hoped when admitted into nursing universities consisted of hospital nurses of 77.2%, while the percentage changed to hospital nurses of 52.8% at the time of this survey. The nurse image represented as an influencing factor, and it was found that if nurse image score increased one unit, the hoping units of career type of hospital nurse increased 2.69 times. Conclusion: The educational institutions have to provide career education programs and information concerned to not only hospital nurses but also community nurses, and further studies on the positioning and expanding roles of community male nurses need to be conducted.
