본 논문에서는 자동으로 꼴을 인식하는 시스템을 제안한다. 기존 연구에서 제안한 방식은 대부분 사용자가 직접 꽃의 윤곽선을 조정하는 방식을 사용하였다. 이러한 방법은 사용자 편의성 측면에서 비효율적이므로 본 연구에서 제안하는 시스템은 사용자와의 상호작용 없이 영상처리만을 이용하여 꽃을 인식할 수 있는 방법을 제시한다. 서버-클라이언트 형태로 구성된 꽃 인식 시스템은 사용자가 전송한 영상의 컬러와 경계선 정보를 기반으로 영상 내에서 꽃의 영역을 찾는다. 꽃의 영역에서 색상과 윤곽선 정보를 추출한 뒤, k-means 클러스터링과 히스토그램 매칭을 통하여 서버에 저장된 기준 이미지와 가장 일치하는 꽃을 탐색하여 사용자에게 알려준다. 100종류의 꽃에 대하여 한 종당 각각 5 가지의 영상을 가지고 실험을 한 결과, 90.8%의 인식률을 얻을 수 있었다.

New mobile phones with high tech-camera and a large size memory have been recently launched and people upload pictures of beautiful scenes or unknown flowers in SNS. This paper develops a flower recognition system that can get information on flowers in the place where mobile communication is not even available. It consists of a registration part for reference flowers and a recognition part based on OpenCV for Android platform. A new color classification method using RGB color channel and K-means clustering is proposed to reduce the recognition processing time. And ORB for feature extraction and Brute-Force Hamming algorithm for matching are used. We use 12 kinds of flowers with four color groups, and 60 images are applied for reference DB design and 60 images for test. Simulation results show that the success rate is 83.3% and the average recognition time is 2.58 s on Huawei ALEUL00 and the proposed system is suitable for a mobile phone without a network.

In this paper, we propose method of correlation coefficients between sensors by statistical analysis that selects optimal sensors in odor recognition system of selective multi-sensors. The proposed sensor decision method obtains odor data from Metal Oxide Semiconductor(MOS) sensor array and then, we decide optimal sensors based on correlation of obtained odors. First of all, we select total number of 16 sensors eliminated sensor of low response and low reaction rate response among similar sensors. We make up DB using 16 sensors from input odor and we select sensor of low correlation after calculated correlation coefficient of each sensor. Selected sensors eliminate similar sensors' response therefore proposed method are able to decide optimal sensors. We applied to floral scent recognition for performance evaluation of proposed sensors decision method. As a result, application of proposed method with floral scent recognition using correlation coefficient obtained recognition rate of 95.67% case of using 16 sensors while applied floral scent recognition system of proposed sensor decision method confirmed recognition rate of 94.67% using six sensors and 96% using only 8 sensors.

The aim of this study is to analyse misinformation about gymnosperm taxon used for over 57 years, since 1957 when plant biology as a discipline was established in our country. That is, terminologies and descriptions of the reproductive structure (flower) of angiosperms (flowering seed plants) have been incorrectly applied to the reproductive structures (typically cones and pollen grain) of gymnosperms (non-flowering seed plants) by numerous and various media such as text books, dictionaries, and internet websites for plant biology. Thus, these resources have been misleading teachers, students, and other people interested in plant biology in general and taxonomy in particular by describing gymnosperm reproductive structures as if they are the same as angiosperms. Such a practice has an especially adverse effect on plant biology education at all levels of instruction, with teachers and students confused in their understanding of the concept and definition of a flower. In this paper, these incorrect expressions for the reproductive structures of gymnosperms from the various media are analysed and discussed in terms of cladogram, anatomy of reproductive structures, and historical context of classification systems.

기능성 꿀 및 그 생산에 대하여 관심이 있다면 우선 벌과 꽃과 꿀의 등식관계(벌=꽃=꿀)를 이해하고 벌꿀의 이용역사를 고찰하여 향후 이용 변화추위에 따라 소비자을이 선호하는 꿀을 생산하여야 할 것으로 본다. 인간에 대한 의학이 발달은 꿀에 대한 소비자들의 인식을 변화시키고 있으며, 건강 증진 및 장수를 위한 well-being 생활의 추구에 따라 식생활도 변화하고 있기 때문에 꿀에 대한 재평가가 요구되고 있다. 따라서 수명과 관련하여 건강증진에 유익한 기능성 꿀 생산은 매우 적절한 대응전력이라고 생각한다. 기능성 꿀벌 생산하려면 꿀에 대한 성분과 특성을 이해하고 기능성물질의 탐색과 더불어 벌을 통한 생산방법을 개발하여 가치 있는 기능성 꿀을 생산하여야 함으로 기능성 꿀 및 생산에 관한 정보를 제공하고자 한다.

This study was attempted to identify the effect of university students on their childbirth willingness, provide it as basic data for childbirth encouragement policies, and contribute to the composition of educational data. Multiple regression analysis of data from 195 university students using the SPSS/WIN 22.0 program. The more conservative the view of marriage (r=.142, p<.05) and the higher the degree of awareness of childbirth encouragement policy(r=.258, p<.01), the more significant the correlation was childbearing willingness. The conservative marriage values, youth job policies, and the degree of recognition of work-family balance support influenced the childbearing willingness, and these variables explained the childbearing willingness 9.2%.

The purpose of this study was to examine the elderly care facilities worker's attitude and awareness of associated factors of falls. The subject was 194 the elderly care facilities workers in Chungbuk. Descriptive statistics, t-test, ANOVA, Pearson correlation coefficient was utilized for the data analysis. The results of this study were as follows. the score of attitude was $2.98{\pm}.34$ out of 4, the score of awareness of associated factors was $3.00{\pm}.43$ out of 4. There were statistically significant differences of attitude and awareness of associated factors of falls according to general characteristics. the relationship of attitude and awareness of associated factors of falls was significantly positive. Falls is important health related problem in elderly care facilities, so effective fall prevention program is needed for elderly care facilities worker.

We identified the diversity, geographical distribution, ecological characteristics of birds, trees, and flowers species designated as local government symbols as a means for understanding public awareness on biodiversity. A total of 114 species including 48 birds, 40 flowers, 36 tree species belonging to 40 orders 59 families 90 genus were designated as natural symbols. Pica pica (L.) in birds, Rhododendron schlippenbachii Maxim. among flowers, have also been designated as symbols. The tree Ginkgo biloba L. was designated with the highest frequency. Local governments located coastal area were selected bird species of the Laridae family and the tree species Camellia japonica L., of Pinaceae as their natural symbols. In contrast, local governments located inland have designated resident bird species such as P. pica and Columba rupestris (Pallas) and flower species from the Ericaceae as natural symbols widely distributed and easily observed throughout South Korea. However, many local governments have designated the same species as a natural symbol based on their size color and public appeal and popularity. The information about the popular species and their ecological traits are useful for establishing the criteria as flagship or iconic species selection and their roles in habitat conservation.

For this study, 313 pedestrians, including students, from two schools participated in the greening project of the school commuting roads in Seoul. These schools were compared to two without street greenspaces to analyze the effects of the green areas on pedestrian satisfaction and the future direction of creation. As a result of the greenspace satisfaction analysis of schools with greenspace, the items that had the greatest effect on overall satisfaction were 'Width of the sidewalk' (37%), 'Harmony with the surrounding landscape' (24.97%), 'The arrangement of trees, grass, and flowers' (18.30%) and 'Overall management' (10.44%). In other words, the item that satisfies most is securing the appropriate width of the sidewalk where the greenspace is located. It is necessary to re-considered creating greenspaces in existing sidewalk spaces and secure a sidewalk width for pedestrian convenience. As a result of the analysis on the direction of greenspace creation, the respondents who experienced greenspaces through the greenspaces on school commuting routes recognized natural features, such as grass and flowers as more important elements as well as noting that landscape and harmony are important. In addition, respondents interested focusing on functionality recognized the need for greenspaces and highly recognized the importance of arranging natural materials, such as trees, grasses, and flowers. This group also recognized the advantages of functionality and the effectiveness of green spaces. Therefore, it is necessary to expand awareness of the effectiveness of greenspaces through environmental education, publicity, and the provision of information boards. More effort will be needed to apply regional and school characteristics rather than uniform composition to the development of greenspaces.
