  • On an international scale, the burden of cancer in absolute numbers continues to increase, mainly due to aging of population in many countries, the overall growth of the world population, changing lifestyle with increasing cancer-causing behavior, like cigarette smoking, changing dietary habits and sedentary life. Cancer is the second-leading cause of death and disability in the world, after only heart disease. Recently, increasing incidence and mortality of cancer have also become evident in the developing world. In Iraq and particularly in Basrah in the southern part of the country, the burden has definitely increased and deserves extensive research. The present paper is part of an extensive household survey carried out in Basrah in 2013. Among the objectives was to validate official cancer registration in the governorate. The cross-sectional survey had a retrospective component to inquire about the incidence of cancer and cancer-related deaths during the three years preceding the date of inquiry (2010-2012). A convenient sample of 6,999 households with 40,688 inhabitants using multistage cluster sampling was surveyed involving all urban and rural areas of Basrah. The official cancer registration activities in Basrah seemed to have attained a high level of registration coverage (70-80%) but the gap, represented by missed cases, is still high enough to criticize the system. Most of the missing cases were either not notified by treating facilities or they were diagnosed and treated outside Basrah. Using a set of parameters, the pattern of cancer was consistent based on data of the household survey and data of the cancer registry but a gap still existed in the coverage of incident cancer and mortality by cancer registration. Integrated serious steps are required to contain the risk of cancer and its burden on the patient through improving the registration process, improving early detection, diagnostic and management capabilities and encouraging scientific research to explore the hidden risk factors and possible causes of low registration coverage. Periodic household surveys seemed feasible and essential to support routine registration.

  • Purpose: This study was performed to identify the factors which affected exercise and the perceived exercise behaviors in women according to Q-methodology and to provide basic strategies for health promotion of middle-aged women in Korea. Method: Q-methodology provides a scientific method for identifying perception structures that exist within certain individuals or groups. Thirty subjects in Seoul, Incheon, Chung-buk classified 35 selected Q-statements in to 9 points standard. The collected data was analyzed by using a QUANL pc program. Result: Principal component analysis identified 3 types of exercise behavior of middle-aged women in Korea and named by the researcher. They are called persistent activity preference type, living-exercise preference type, exercise mania type. In persistent activity preference type, the middle-aged women thought activity was very helpful to achieving health and releasing stress or fatigue. Also, they recognized the relationship between physical health and psychological health. In living-exercise preference type, the middle-aged women preferred maintaining stability or nonactivity to intended exercise or activity for health. In exercise mania type, the middle-aged women thought there was no other way to keep her health than to exercise. Conclusion: The findings of this study will provide the health care provider including nurse with useful information. It's very important to offer appropriate exercise intervention to the middle-aged women of each type by taking into consideration the characteristics of individual types.

  • Volcano hazard mapping became a focus of scientific inquiry in the 1960s. Dwight Crandell and Don Mullineaux pioneered the geologic history approach with the concept of the past is the key to the future, to hazard mapping. The 1978 publication of the Mount St. Helens hazards assessment and forecast of an eruption in the near future, followed by the large eruption in 1980 demonstrated the utility of volcano hazards assessments and triggered huge growth in this area of volcano science. Numerical models of hazardous processes began to be developed and used for identifying hazardous areas in 1980s and have proliferated since the late 1990s. Model outputs are most useful and accurate when they are constrained by geological knowledge of the volcano. Volcanic Hazard maps can be broadly categorized into those that portray long-term unconditional volcanic hazards-maps showing all areas with some degree of hazard and those that are developed during an unrest or eruption crisis and take into account current monitoring, observation, and forecast information.

  • The purpose of this study was to compare the written tests of the science lessons at elementary schools with the instructional objectives of the teachers' guide for the first term of the 5th grade by using Klopfer's taxonomic system. In the analysis of the instructional objectives in the teachers' guide, A.0(40.0%) and $B.0{\sim}E.0$(42.4%) showed high level but the proportion of processes of F.0(5.6%), G.0(4.0%), H.0(4.0%), and I.0(4.0%) showed low level, while in the written tests A.0 was 54.8%, $B.0{\sim}E.0$ was 36.1%, F.0 was 7.3%, and G.0 was 1.8% but H.0 and 1.0 was not taken at all. In the comparison with the instructional objectives in the teachers' guide about the domain of the knowledge and the comprehension showed hish and the processes of the scientific inquiry showed relatively low. The results of this study suggested that a desirable written test should be made to consider elementary science curriculum and instructional objectives and hold up rates of each behavior category between the instructional objectives of teachers guide and assessment objectives of written tests.

  • 현재 과학교육의 목표는 과학적 소양의 함양이며 이를 구현하기 위해서는 교실에서의 과학탐구의 실현을 필수로 하고 있다. 과학자들이 경험하는 과학탐구는 "실질적 과학탐구(ASI)"라고 하여 필수적인 5가지 탐구요소(문제제기, 자료수집, 설명형성, 설명평가, 발표 및 정당화)를 포함하고 있다. 현재 사용하고 있는 지구과학내용의 교과서를 이 ASI 관점으로 분석하여 5가지 탐구요소의 분포도를 분석하고 이를 이용하여 지구과학탐구를 가르치는 초임교사를 대상으로 탐구에 대한 인식 및 교수실천을 같은 ASI관점으로 분석하였다. 탐구요소 2,3,4 에 해당하는 '증거수집', '설명형성' 그리고 '설명평가'는 빈번하게 나타났으나 탐구요소 1에 해당하는 '문제제기'나 5에 해당하는 '발표 및 정당화'의 기회는 나타나지 않았다. 특히 다른 과학(화학)과목 경우에 '증거수집'이 가장 빈번한 것에 비해 지구과학의 경우에는 '설명형성'이 주를 이루는 것은 지구과학탐구의 특징이라 할 수 있겠다. 또한 교과서 탐구기능은 SAPA로 분석한 결과 일반화, 의사소통, 예상, 그래프작성, 자료해석이 주를 이루었다. 과학적 소양을 함양을 위한 실질적인 과학탐구의 실현하기 위해서는 자유탐구와 같은 부차적인 기회를 통해서 경험하지 못한 ASI의 탐구요소의 기회를 학생들에게 부여해야 할 것이다. 또한 이 연구에 참여한 지구과학 초임교사의 과학탐구 인식 및 교수실천 또한 ASI로 분석한 결과 탐구요소 2번째에 치우친 경향을 보여주고 있었다. 실질적인 과학탐구의 실현을 위해서는 교과서에서 강조되는 탐구요소뿐만 아니라 다른 탐구요소를 경험할 수 있는 자유탐구를 개발하여 실용화해야 할 것이며, 관련 초임교사연수를 통해 초임교사들의 과학탐구에 대한 인식 및 교수실천의 반영 및 이들의 새로운 형성이 추진되어야 할 것이다.

  • When Web-based special retrieval systems for scientific field extremely restrict the expression of user's information request, the process of the information content analysis and that of the information acquisition become inconsistent. Accordingly, this study suggests the re-ranking retrieval model which reflects the content based similarity between user's inquiry terms and index words by grasping the document knowledge structure. In order to accomplish this, the former constructs a thesaurus and similarity relation matrix to provide the subject analysis mechanism and the latter propose the algorithm which establishes a search model such as query expansion in order to analyze the user's demands. Therefore, the algorithm that this study suggests as retrieval utilizing the information structure of a retrieval system can be content-based retrieval mechanism to establish a 2-step search model for the preservation of recall and improvement of accuracy which was a weak point of the previous fuzzy retrieval model.

  • Experimental animation is an independent art animation and a visual art that is integrated with the spirit of experimentation. Norman McLaren pursues original beauty in each piece through scientific exploration of visual expression technology and experiment that transcends common sense with great creativity and sensitivity, and the aesthetic value of animation is very high as the master of experimental animation that has brought innovation of real image media today. Therefore, it is meaningful to analyze the experimental expressions of Norman McLaren, who expanded the field of experimental animation by challenging various techniques and carried out a ceaseless search for motion creation between each frame, and to study the expressions of movement he focused on. The most significant feature of his movement expression was analyzed as repetition of motion and repetition of metamorphosis. I hope that this derivation will be understood as experimental animation of experimental method which requires more specific type of inquiry than simple question about experimental method. Also, I hope that it will be meaningful as a preliminary study to deeply explore the possibility and direction of animation creation in university education.

  • The purpose of this study is to analyze the curriculum of a university-affiliated science gifted education center based on the core competencies and to suggest a direction for improving the education at the gifted education center. For this purpose, we set the 12 core competencies as follows: 6 cognitive competencies such as knowledge, creativity, scientific thinking ability, inquiry ability, problem solving ability and fusion ability, and 6 non-cognitive competencies such as task commitment, self-directed learning ability, motivation reinforcement and challenge, communication skills, collaboration ability and leadership. The curricula of the science gifted education centers reflect all the competencies, but some competencies are only potentially included in the contents of the programs. In this study, we present examples of education programs by each competences and suggest additional descriptions for the development of gifted education centers.

  • Stormwater management is an essential component of land-use planning and development. Due to the additional challenges posed by climate change and urbanization, various stormwater management schemes have been developed to limit flood damages and ease water quality concerns. Nature-based solutions (NBS) are increasingly used as cost-effective measures to manage stormwater runoff from various land uses. Specifically, constructed wetlands were already considered as socially acceptable green stormwater infrastructures that are widely used in different countries. There is a large collection of published literature regarding the effectiveness or efficiency of constructed wetlands in treating stormwater runoff; however, metadata analyses using bibliographic information are very limited or seldomly explored. This study was conducted to determine the trends of publication regarding stormwater treatment wetlands using a bibliometric analysis approach. Moreover, the research productivity of various countries, authors, and institutions were also identified in the study. The Web of Science (WoS) database was utilized to retrieve bibliographic information. The keywords ("constructed wetland*" OR "treatment wetland*" OR "engineered wetland*" OR "artificial wetland*") AND ("stormwater*" or "storm water*") were used to retrieve pertinent information on stormwater treatment wetlands-related publication from 1990 up to 2021. The network map of keyword co-occurrence map was generated through the VOSviewer software and the contingency matrices were obtained using the Cortext platform (www.cortext.net). The results obtained from this inquiry revealed the areas of research that have been adequately explored by past studies. Furthermore, the extensive collection of published scientific literature enabled the identification of existing knowledge gaps in the field of stormwater treatment wetlands.

  • This study investigates the integration of astronomy-related topics in the Korean national science curricula spanning from 1945 to 2023. We analyze the placement and extent of astronomy content across different school levels. Astronomy contents in the science curricula have changed in response to social needs (e.g., practical knowledge required for agriculture and fishery) and advancement in astronomical research (e.g., the discovery of exoplanets and the suggestion of new cosmological parameters). Contents addressing the motions of celestial objects and stellar physical properties have remained relatively consistent. In the latest 2022 revised national curriculum, scheduled for implementation in 2024, several elements, such as coordinate systems, have been removed, while the inquiry activities using digital tools are emphasized. The incorporation of the cosmic perspectives in the national curriculum, as well as astronomy education within the context of education for sustainable development, remains limited even in the most recent curriculum. For future life revisions, the active participation of researchers is needed to reflect the latest astronomical research progress and scientific characteristics in the field of astronomy.
