Although improper integrals constitute a concept of great utility for Mathematics students, it appears that students are unable to assimilate this concept within the wider system of concepts they learn in their first year of Mathematics studies. In this paper we describe a competence model used in a study about the kind of understanding students possess about improper integral calculus when two registers of representation come into play. Competence will be considered as the coherent articulation of different semiotic registers. After analysing the results of a questionnaire, six students were selected to be interviewed on the basis of their overall results and the significance of their answers. For the interview, five original questions from the questionnaire were used together with a new question. In this article we will analyse, from our theoretical point of view, the work carried out by one student who was interviewed to show how our competence model works and we will discuss this formal competence model used.

Although the general concept of suffering care includes palliative care for the terminally ill that is designed to alleviate pain, it is much more holistic and encompasses emotional, spiritual and other life dimensions. Human suffering is multi-dimensional including spiritual and religious aspects, which diverge from the concept of pain understood in the context of materialistic medical approach. In this caring perspective, the body, mind and spirit are integrated so that objectivity and subjectivity can merge. The extended awareness with inner source or energy, and positive thinking about the personally-relevant God can be meaningful the dying person, family members and the caring team. Despite the importance of an inclusive understanding of human suffering, actual nursing practice still does not fully embrace the full understanding of human suffering. A more fundamental meaning of human suffering from the nursing perspective may fruitfully adopt a more inclusive view of human suffering.

This research examines the concept of 'homo sovieticus' by reviewing the sociological essay novel homo sovieticus written by Zinoviev who was one of the well-known dissident in Soviet Union period, and attempts to have critical understanding of the concept. It is an interesting research topic that current Russia and Russians who get through the historical layers from Soviet to post-Soviet regime at the time current trend that allows to have various academic discussions of post-Soviet. It is required to examine the past of Russia and Russian to make precise estimation of their current and future. Therefore, it is necessary to re-examine the term of 'homo sovieticus' which is conventionally accepted. This research aims at broad comprehension of homo-sovieticus by focusing on the Zinoviev's own understanding instead of the habitual use of the term which only contains ideological and political intention.

The purpose of this study was to analyze the understanding of the sighting and hearing elementary school students have through drawing. For this purpose, we conducted a questionnaire survey of 602 elementary school students. The questionnaire was composed with open-ended question developed by West et al.(2008). This questionnaire was presented only appearance of face. And let them express the sensory pathway by drawing and writing. The students' responses for questionnaire were classified by 5 levels. Inner-researcher consistency was 0.89, inter-researcher consistency was 0.83. The data analyzed were ${\chi}^2$ by using SPSS. The result of this study were as following: First, elementary school students have misconception of sighting and hearing. There were no difference among the grade. In spite of becoming upper grade, students have still misconception. Second, scientific concept that male students have were significantly more than female. Third, the concepts of the anatomically organs are more exposed in real-life situations, students known better. Within these results, it would be used for developing teaching-learning strategies which can use misconceptions students have.

Science, Mathematics, Engineering, and Technology (STEM) integrated education has been spotlighted as a new approach for promoting students' conceptual understanding and supporting their future career in STEM field. There is increasing evidence of the positive impact of using a whole design process that can be an example of STEM integrated activities to improve students' conceptual understanding and problem solving skills. However, there is a lack of information on how teachers should accomplish science and engineering integration activities in their classroom and what process they should pay attention. To answer this question, we research the relationship between an design process and students' conceptual understanding using an engineering design activity, called 'Save the Penguins', and study on how each step in an engineering design process in this activity enhance students' conceptual knowledge in science. We found that testing their prototypes and discussing with their peers were the most important process for students to understand and apply science concept for their design, even though the whole engineering design process (demonstration about radiation, discussion about examples in our lives, and testing and reviewing their prototypes, and making final design) helps the students understand the scientific concepts.

The development of stream ecology, especially the progress of that field in North America, has been briefly reviewed, and stream studies in Korea were analyzed through literature survey. During the last two decades, theoretical advances in stream ecology and understanding of the structure and function of stream ecosystem were made from the studies mainly in North America. Early studies (1960-1970) focused on determination of the environmental factors controlling the distribution and abundance of organisms dwelling in streams. Introduction of conceptual development, such as the functional feeding concept, river continuum concept, and nutrient spiraling was notable in the late 70's and the 80's. For last 20 years, experimentation approaches to apply ecological principles were very fruitful in the understanding of community structure. Even though studies on the stream ecosystem is Korea have a long history, most of works were concentrated on limited subjects: water quality, abundance and distribution of aquatic insects and fishes. Basic ecological attributes of stream organi는 and test of ecological principles have rarely been a subject of research topics. We must concentrate our effort to enhance our understanding of stream and river ecosystem through qualitative, experimental and interdisciplinary approaches.

The purpose of this study was to examine the effects of traditional fairy tales on the basic understanding of economics and numbers for 4 year old preschoolers. The subjects were 20 children at one education center located in Seoul: Among them, 10 were in the experimental group and 10 were in the control group, based on random selection. The program for economic education was conducted for eight weeks; two times each week for the experimental group, while a general curriculum was conducted with several traditional fairy tale books related to economic education were given to the control group. The preschoolers' basic understanding of economics and numbers was examined using the scales of Park(2008) and Choi(2003). Collected data was analyzed by t-test and ANCOVA using SPSS 17.0 program. The results were as follows: there were significant differences in the understanding of economics and numbers according to economic education based on traditional fairy tales respectively. In conclusion, it is necessary to conduct a scientific study in order to develop an economic education program. Also, various activities were discussed to use the economic program for preschoolers.

Although the general concept of suffering care includes palliative care technology for terminally ill person to alleviate his pain, it is much more holistic including emotional, spiritual and other life dimension. This inclusive concept of caring can be possible with the fundamental reflection on the human suffering. Far from the concept of pain understood in the context of materialist medical approach, human suffering has many dimensions including aesthetic, psychological, and religious: its meaning is holistic. With this perspective, the experience of the suffering client must be reconsidered before one starts with an objective side or a subjective side of suffering. Indeed, the actual strategies of suffering care can be different depending on the definition of human suffering accepted by practicians. In this caring perspective, the body, mind and spirit are integrated so the objectivity and subjectivity can merge; the extended awareness with inner resource or energy, and the positive thinking about the God is meaningful especially for dying person, his family members and the caring team. Despite this impending importance of the inclusive understanding of human suffering, the actual nursing practice still does not reflect this growing understanding of human suffering. This approach, which tried to pursuit the more fundamental meaning of human suffering, can contribute to the development of nursing education and practice which pay attention to the more inclusive view of human suffering.

According to Piaget, children aged 11 are in the middle of concrete operation period and formal operation period. So, it is necessary to adopt the Learning Cycle Model (LCM) which helps students improve their cognitive development. After determining the test for the Science Concept of Matter (SCOM), the experimental group showed higher average than the comparative group in the post-test. In the sound understanding, the experimental group showed higher ratio than the comparative group. And in the ratio of imperfect, wrong understanding and no response, the experimental group was lower than the comparative group. On the questions that were needed the complicated inquiry, many students of both groups still couldn't find the fundamental cause. In forming the scientific conceptualization, there was a meaningful difference (p < .001) after post-test Analysis of Covariance (ANCOVA) with pre-test result. After determining the test for the Test Inquiry Science Process (TISP), the experimental group showed higher average than the comparative group in the post-test. In the category of basic inquiry process which is needed in concrete operation, there was a meaningful difference (p < .05). In the category of unified inquiry process which is needed in formal operation, they showed no meaningful difference (p > .05). Therefore, applying the LCM to the chapter of 'Solution and Dissolving' is more effective on improving the scientific conceptualization and on helping the concrete operation abilities than the teacher centered learning.
