This study attempts to examine farmers' preference and perception towards cropland agroforestry (CAF) and its economic benefits in Bangladesh. It surveys 84 farmers of two sub-districts named Manirampur and Bagherpara under Jessore district of Bangladesh to address the study objectives with the help of a questionnaire during the period of June to July 2013. We follow a multistage random sampling procedure for selecting respondents of the survey. A total of 27 plant species under 19 families are identified in the surveyed crop fields, among which 11 are tree species and 1 is shrub from 8 families and 15 species are agricultural crops from 11 families. According to the survey findings, most of the farmers prefer multipurpose tree species like Swietenia macrophylla (67 percent), Phoenix sylvestris (48 percent), Mangifera indica (48 percent) and Cocos nucifera (43 percent). We also find that Curcuma longa (92 percent), Oryza spp. (56 percent), Solanum melongena (43 percent) and Amorphophallus campanulatus (33 percent) are the available agriculture crops which are grown in association with trees in the study area. The surveyed farmers report that they practice CAF to get fuel wood, fodder, juice, fruit and food for family consumption and revenue earnings. About 76 percent of the surveyed farmers endorse the existence of a positive interaction between trees and agriculture crops, while the rest 24 percent endorse the existence of a negative interaction between trees and agriculture crops. This study finds that CAF farmers on an average earn US$ 1,410 per farm per year and the yearly average revenue difference between CAF and non-cropland agroforestry (NCAF) farmers is US$ 214. Overall, CAF needs to develop through scientific intervention in the study area to conserve the biodiversity and to enhance farmers' sustainable livelihood.

This article does not deal with a theory or theories in the usual sense of the term but rather harks back to its etymological source, theorein ' to look at.' The phrase 'theory of language' thus purports a 'view of language' and does not carry the force of scientific explication of language. In fact, the word ' scientific' or 'science' per se originates from scire 'to know' and is here to be considered not so much in regard to some kind of positivistic methodology as a form of knowledge. If this exposition sounds unduly ingenious, that is because one is caught up in all kinds of presuppositions about the words under consideration. Sometimes, when we come to grips with an issue that strikes our mind as truly important, our language, by the light of which we hope to proceed safely, plays the will-o'-the-wisp instead and leaves us in the middle of a murky maze, twisting what was at first blush a mere cinch into a Gordian knot. On such occasions, etymology comes along the way and sends us back to itself as its own principle: Resort to etymos logos 'original, true word'! The main thrust of the present study is that alongside the quantitative, positivistic thought there is another equally valuable mode of qualitative and humanistic thinking that makes a whole gamut of new and concrete investigations possible, that an integrated theory of language is Possible by way of a happy amalgamation of diversified, humanistic views of language. With this idea as the leitmotif we explore two models of theory which typically set themselves up for a 'scientific' approach to language: analytic philosophy that delves into what it calls logical simples, and contemporary linguistics that stubbornly teeters around some formal rigor or other. It is argued that they are both characterized by a looking away from the fluid, ill-definable aspects of language, giving a preference to segments and isolated facts as a means to avoid those larger wholes and totalities which if they had to be seen would in the long run lead to an uncomfortable state of mind. Language, in the final analysis, is a Protean entity: so capricious and multifarious, and yet so noetic and prophetic, that we should catch sight of its picturesque images in their entirety to give form to an integrated theory of language.

이 연구에서는 초등, 중, 고등학교의 학생과 교사가 선호하는 SSI 주제를 조사하여 학교급별 학생과 교사가 선호하는 SSI 주제의 유사성을 코사인 유사도 측정을 통해 분석하였다. 연구 대상은 초, 중, 고등학생 566명, 교사의 327명이었다. SSI 관련 선행연구 논문과 프로그램에 포함된 SSI 주제 60개를 환경, 과학기술, 보건·의학, 기타 사회 문제 영역로 구분하고 목록화하여, 연구 대상인 학생 또는 교사가 선호하는 주제 5개를 선택하도록 하였다. 자료수집은 서베이몽키를 이용한 온라인으로 진행하였고, 수집된 자료는 학생 및 교사별로 6개 집단으로 구분하고, 집단별로 주제의 선택 빈도를 조사하였다. 그리고 선택된 주제의 빈도를 기준으로 벡터 값을 계산하고, 학교급별 학생 간, 교사 간, 교사와 학생 간의 코사인 유사도를 측정하여 주제 선호 유사도를 분석하였다. 연구결과는 다음과 같다. 첫째, 학생의 학교급별 집단간 SSI 선호 주제 유사도는 중학생과 고등학생 사이의 코사인 유사도(0.982)가 초등학생과 중학생간(0.651) 또는 초등학생과 고등학생간(0.662)의 코사인유사도보다 높았다. 둘째, 교사의 학교급별 집단간 SSI 선호 주제 유사도는 초등, 중, 고등학교간의 모든 비교 집단에서 비교적 비슷한 코사인 유사도의 양상을 보였다. 셋째, 학생과 교사간 학교급별 SSI 선호 주제 유사도는 초등학교 학생과 교사 집단간 코사인 유사도(0.974)가 다른 학교급의 비교 집단, 중학교급(0.621) 또는 고등학교급(0.645)보다 높았다. 즉 초등학교의 학생과 교사는 서로 선호하는 SSI 주제가 73.33%의 수준에서 유사하고, 반면, 중학교 또는 고등학교의 학생과 교사는 서로 선호하는 주제가 33% 수준으로 유사한 경향을 보였다. SSI 교육에서 학생에게 관심 있는 주제로 접근하는 것은 학습 동기 유발과 지속, 그리고 즐거운 학습 경험과 학습에 대한 긍정적인 태도 형성과 긴밀하게 연관된다. 따라서, SSI 수업을 설계할 때, 학생 관심의 관점에서 주제를 검토해야 할 것이다. 특히 교사가 학생의 선호도와 다소 차이가 있는 SSI 주제를 선별한 경우, 그 차이를 극복할 수 있는 치밀한 교수 설계가 필요할 것이다.

The purpose of this study is to suggest objective basic data for environmental resource planning through the evaluation of the visual quality by GIS. For this, Landscape information system have been made up of topographical and superficial information and landscape values of Cheju Island have been evaluated by using Grass 4.1, degree of visual preferences have been measured mainly by questionnaires and finally these data have been analyzed by using the correlation. Result of this study can be summarized as fellows, in the landscape value, remarkable views play a role as the dominant landscape information. Also, LCPs including various, successive view or a lot of visibility amount have high Landscape value. Therefore, it is important to management landscape which can preserve values of landscape elements through the creation of visibility area. In the visual preference, remarkable scenes play a part as a dominant factor. Also, LCPs including a wide field of vision or successive view have high visual preference. Therefore, it is proved that the visual preference is related to a field of vision and remarkable scenes. Finally, these data have been analyzed by using the regression, in order to verify the method. The result is that a R\sup 2\ is 0.715. It means that correlation is significant at the 0.01 level. In conclusion, the results of this study reveal that visual preference has been evaluated by aesthetic variables and landscape values have been evaluated by GIS. And visual preference and landscape values are closely correlated. In other words, it is possible to evaluate the aesthetic value by physical variable. The method of evaluationi is used in Cheju Island, and it will be possible to apply this method to other places. And this method can be applied to other places by special quality and landscape informatioin system, made up of landscape elements. Also, it will be possible to keep up management and applicatioin that is evaluated by GIS and computer program. Recently, there is a tendency tat visual and aesthetic approach, based on planners' experiences and intuitioin is gradually changed to the scientific approach, based on a objective data. Therefore, it is important that the measuring system is based on objective data which are concerned with a special quality of landscape. It is also significant that the environmental planning is based on a spatial image of physical environment and major landscape elements.

This study examined young Korean children's perceptions about scientists, kindergarten science and the application of science in their daily lives. An interview questionnaire developed by the researchers and based on Chamber (1983)'s Draw-A-Scientist Test (DAST), was administered to 104 five-year-old children. Most of the children (68.2%) saw themselves doing activity-oriented science in kindergarten, but they did not use outside kindergarten for the knowledge and skills they learn in science (70.4%). In general, children recognized scientist as a male working with lab equipment in the laboratory. Although most of children (74.5%) were interested in science, only a few of them (12.5%) hoped to be a scientist in the future. There were significant differences attributable to gender in preference for science; girls showed more interest in science than boys.
