  • Vietnam is the country with the largest animal feed production in Southeast Asia. Domestic animal feed manufacturing enterprises play an important role in animal husbandry in particular and in agriculture in general. However, domestic animal feed enterprises in Vietnam are encountering shortcomings. This paper is conducted to investigate the impact levels of external determinants on business performance of domestic animal feed manufacturing enterprises, including: (i) policy and economic mechanism, (ii) supply-demand of animal feed products, and (iii) nature and level of market competition. We presented a research method, explaining the dependent variable 'business performance' and the independent variables. Data were collected from 120 questionnaires from domestic animal feed manufacturing enterprises. Based on these data, we use Cronbach's Alpha, EFA and run regression model for assessing the impact levels of each independent variable on the dependent variable of business performance of domestic animal feed manufacturing enterprises. The results show that three external determinants including (i) policy and economic mechanism, (ii) supply-demand of animal feed products, and (iii) nature and level of market competition, have positive relationships with business performance. Based on the findings, some recommendations are given for improving business performance of domestic animal feed manufacturing enterprises to ensure sustainability.

  • This study aims to understand the degree of inequality of surveyed amenity resources and identify which resource and region have the highest concentration by estimating Lorenz Curve and the Gini's Coefficient. The Lorenz Curve and Gini's Coefficient derived from economics are introduced as tools for investigating and quantifying regional variability of amenity resources concentration. This study describes the concepts underlying the application of the Gini's coefficient to measure the concentration of amenity resources in 11 regions, Chungbuk Province, Korea. The Lorenz Curve presents a graphical view of the cumulative distribution of amenity resources and the Gini's Coefficient provides a single-parameter measure of the distributional concentration of amenity resources. Also the Gini's Coefficient is compared to the number of amenity resource for understanding distributional difference between concentration and quantitative distribution of amenity resources. The results demonstrate significantly different regional variation according to the amenity variables: almost intact nature, interaction between nature and man, man-made.

  • The purpose of this study is to examine the level of aggressive tax planning (ATP) among companies listed in the Access, Certainty, Efficiency (ACE) Market of Bursa Malaysia. On top of that, this study also investigates the relationship between company characteristics, ethnicity, and ATP. This study uses a balanced pooled sample of 105 firm years-observations for the period from 2014 to 2018. These samples were selected to provide new insight into this market and to explore the attitude of small firms toward ATP in Malaysia. The data was retrieved from DataStream and the downloaded annual reports. The finding shows that profitability and financial distress have a significant relationship with ATP. Other variables including size, capital intensity, inventory intensity, leverage, and ethnicity, were not determinants of ATP. The result in this study may assist the reader in understanding the nature of companies in the ACE market, particularly on its behavior toward tax planning. A strict requirement is needed to be adopted in the sample selection process, thus limiting the sample size. Further, since the previous study focused on large companies, the discussion of this paper will provide new insight into the nature of tax planning within the small- and medium-sized companies in Malaysia.

  • Decision models are an attempt to reduce uncertainty in the decision making process. The models describe the relationships of variables and given proper input data generate solutions to managerial problems. These solutions may not be answers to the problems for one of two reasons. First, the data input into the model may not be consistant with the underlying assumptions of the model being used. Frequently parameters are assumed to be deterministic when in fact they are probabilistic in nature. The second failure is that often the decision maker recognizes that the data available are not appropriate for the model being used and begins to collect the required data. By the time these data has been compiled the solution is no longer an answer to the problem. This relates to the timeliness of decision making. The authors point out throught the use of an illustrative problem that stocastic models are well developed and that they do not suffer from any lack of mathematical exactiness. The primary problem is that generally accepted procedures for data generation are historical in nature and not relevant for probabilistic decision models. The authors advocate that management information system designers and accountants must become more familiar with these decision models and the input data required for their effective implementation. This will provide these professionals with the background necessary to generate data in a form that makes it relevant and timely for the decision making process.

  • Rock masses represent natural systems that are inherently complex and in which multiple mechanisms occur. Rock engineering systems such as tunnel and slope interact with surrounding systems through an exchange of both mass and energy. Accordingly the complex nature of rock masses calls for a system approach, and the open nature of rock engineering even requires the engineering to be controlled by a system approach for surrounding environments. However, traditional methods cannot take all variables and their interactions into account and are limited to the system with single mechanisms. Therefore, they are not proper for a complex and open system, and also cannot portray the whole system. Thus, a system approach is indispensable to rock engineering for dealing with the whole of a complex and open system. In this paper Mechanism Path Analysis Methodology (MPAM) Is Introduced for a system approach to rock engineering. The analysis by the methodology gives us all the information of systems behavior in the context of the whole system in order to accomplish the optimum design in accordance with the project objectives and analysis purposes. As an application a conventional model for the evaluation of TBM tunneling performance system is analyzed by MPAM and the result is compared with that by a traditional method.

  • Background : An important issue in health care today is in trying to center service around the hospitalized patient. There is a "Kindness Movement" developing now, where in the focus of Health Care is being changed from simply treating the basic physical needs of the patient with sophisticated technology, to keeping emotional well being healthy with more humane and attentive treatment. In our attempt to reach the goal of a completely satisfied patient, we undertook a study of the common complaints of patients, and the subsequent nature of the interventions. Method : The study was carried out in two stages, first the patients made known their complaints by filling out questionnaires, then we collected data on the attempts to alleviate the complaints. The questionnaire provided 19 different complaints, which were then analysed for such variables as content, source of complaint, persons treating the complaint, and length of time and method used to solve the complaint. Results : 1. The Chief complaints made by patients(99.1%) were of physical discomfort, such as pain, nausea, vomiting, indigestion, diarrhea and constipation. 2. The complaints were voiced primarily by either of the patient's family, or by the patients themselves(78.4). 3. The complaints were intervened by nurses alone(53.5%), physicians alone(25.5%), or by nurses and physicians together(19.25%). 4, The method by which the complaints were resolved included the utilization of prescriptions(55.7%), further explanation and education(25. 5%) and notification after treatment(13.2%). 5. Most complaints were voiced during the dayshift(42.6%, 7:00-15:00), followed by the evening shift(36.0% 15:00~22:00), and then the nightshift(21.3 %, 22:00-07:00). 6. The time required for successful resolution of the patient's problems varied from 10~88.9min, according to the nature of the complaint. Conclusion : Hopefully by knowing beforehand the nature of both complaint and intervention, we can anticipate problems and shorten reaction time, in order to provide for a more satisfied patient.

  • The networking between the press and elites, and its impact on journalistic activities in fact have been major subjects of scholarly scrutiny particularly among students of elite theory and class theory. This is an empirical analysis of how the press establishes networks with several powers in local community. This study basically examines a set of independent variables, such as the nature of capital and history of local newspapers and explores how the management and elites in the press utilize several social resources and establish networks. Major findings of this study are as follows: To begin with, the networking between local newspapers and elites showes significant differences according to the nature of capital and history of the newspaper. In other words, while the newspapers operated by stock capital revealed high degree of networking with political and financial elites, the newspapers operated by family capital did not demonstrate significant level of networking with particular elites. The shorter the history of newspaper is, the more she tends to be dependent on resources, and feel it imperative to establish strong networks with elites.

  • In this study, we investigated the differences of graph constructed by middle school students in daily-life and scientific contexts according to the views on the nature of scientific measurement. A test consisting of three similar data sets regarding daily-life and scientific contexts was developed, and administered to 151 ninth graders. They were expected to construct proportional, inverse-proportional, and increasing and become constant form of graphs for each data set. Graphs constructed were analyzed in the aspects of constructing a trend line (types of a trend line, interpolation/extrapolation), selecting axes variables, scaling axes, and plotting points. Analyses of the results revealed that the students with set paradigm tended to construct a curved trend line, while those with point paradigm constructed a broken trend line in inverse-proportional graph questions. In the aspects of interpolation/extrapolation, most students with set paradigm performed both interpolation and extrapolation better than those with point paradigm in scientific context. Most students with set paradigm performed both interpolation and extrapolation regardless of contexts, while the proportion of interpolation of those with point paradigm was higher in scientific context than in daily-life context. In selecting axes variables, scaling axes, and plotting dots, there were no statistically significant differences between set and point paradigms. On the bases of the results, educational implications for improving graph construction skills of middle school students are discussed.

  • This study investigated the effects of small group drawing in learning the concepts of particulate nature of matter. Three classes of seventh graders (N = 126) at a coed middle school were randomly assigned to a pair drawing group, an individualistic drawing group, and a control group. The students were taught the 'three states of matter' and 'motion of molecules' for eight class periods. Prior to these classes, student self-efficacy, learning motivation, and attitude toward science instruction were examined. After instruction, tests assessing achievement, conception, learning motivation, and attitude toward science instruction were administered. Two-way ANCOVA results revealed that scores of achievement and conception for the pair drawing group were significantly higher than those for the control group. However, scores of the three groups did not significantly differ in learning motivation and attitude toward science instruction. Furthermore, no significant interactions surfaced between instruction and the level of self-efficacy in all dependent variables.

  • This study is the first part of the investigation of the students' and teachers' understanding of ideal conditions in physics. To do this, here, we provided the theoretical basis for the above study by discussing the meaning and characteristics of idealization. Idealization, introduced and elaborated by Galileo therefore characterized the nature of modem science, can be generated by four procedures: neglecting the minor variables, giving without any description about the minor variables, assuming the limit case, assuming constancy or uniformity. Idealization generated by these procedures can produce models and laws from the sensory informations about real world. And physics world is constructed by formalization or mathematization of these models and laws obtained through idealization about real world. Therefore, it can be said that idealization have a major role in the context of discovery. By this aspects, physics world can be viewed as the approximation of the real world, and this view, again, give rise the philosophical debate about the reality in nature. Idealization take an important role in the process of application of physics world and the understanding the real world. That is, physicists accept the discrepancies between real world, and physics world and make a great effort to explain, moreover, reduce these discrepancies by modifying or eliminating idealization involved in physics world. Continued from this study, we will proceed to obtain the implications of idealization on the physics learning and investigate the students' and teachers' understanding of the ideal condition involved in the theoretical explanation and the experiment in physics.
