부들과에 속하는 한반도 미기록식물인 가는흑삼릉(Sparganium subglobosum Morong)을 최초로 보고한다. 가는흑삼릉은 작은 키, 폭 4 mm 이하로 좁은 잎, 1-2회 분지하는 가는 화축, 성숙시 지름 약 1 cm인 구형 두상 화수 등의 특징에 있어 기존에 우리나라에서 보고된 다른 흑삼릉속 식물과 구분된다. 현재까지 확인된 가는흑삼릉의 2개 분포지 중 1 곳은 최근 심하게 교란되어 지역적인 멸종위협에 놓여 있는 상태이다. 가는흑삼릉에 대한 보전 대책 마련 및 추가적인 분포지 확인이 필요하다. 가는흑삼릉의 기재문, 사진 및 도해 외에 우리나라 흑삼릉속 식물의 검색표를 제시한다.

The purpose of this study was to investigate current garment sizes of women's formal jackets, targeting plus-size women in online shopping malls, and to identify effective size information involved in online apparel purchase behaviors to overcome the short comings of current garment sizes from the perspectives of consumers. Basic 88 size formal jackets from the seven companies found on the 22 websites were collected and analyzed. The data were collected from March to October 2007, and analyzed using SPSS 14.0. The results were summarized as follows. First, there was no website using standard garment size labeling with 'bust-hip-height' set up by KS K 0051 among the 22 websites. Instead, all 22 websites used garment size labeling with figures such as 88, 99, 100, 110, and 120 or with letters such as L, XL, and XXL. The websites presented no body size, but listed garment size. Furthermore, the size information was presented differently, ranging from three items of bust circumference, upper arm length, and jacket length to six items of shoulder width, bust circumference, waist circumference, sleeve width, sleeve length, and jacket length. In addition, no website presented basic information for hip circumference, despite the jacket length covering the hips. Second, a total of 85.7% the websites listed bust circumferences in 88 garment sizes collected as 100cm. Shoulder widths were presented as 39cm or 37cm. Sleeve circumferences were addressed the same, 36cm, in all websites. Third, comparing the differences between guidance sizes and measurement sizes, only 28.5% of the web sites posted guidance sizes of shoulder widths the same as those of the measurement sizes. All web sites presented guidance sizes of bust circumstances as 1 to 5cm smaller than those of the measurement sizes.

본 연구에서는 지리지형정보를 바탕으로 전국규모의 환경정보를 관리하고 환경모델링을 지원할 수 있는 환경지리지형정보시스템을 개발하였다. 이 시스템은 환경지리지형정보 DB(Database)와 이를 이용할 수 있는 소프트웨어(Software)를 통합하여 구성하였다. 환경지리지형정보 DB를 구축하기 위해서 기존의 지리지형정보로부터 환경관리에 필요한 여러 도형정보(점, 선, 면)를 선별하여 추출하였고, 이러한 도형정보에 환경정보를 연결하여 환경지리지형정보를 구축하였다. 환경지리지형정보를 쉽게 이용하기 위해서 비주얼 베이직(Visual Basic) 컴파일러를 이용하여 소프트웨어를 개발하였다. 이 소프트웨어는 DB를 가시화할 뿐만 아니라, 다양한 환경지리지형정보를 손쉽게 검색하고, 노출평가를 위한 환경거동모델링에 필요한 입력데이터를 자동으로 생성하기 위한 유용한 도구이다.

정보교과에서 정보의 표현과 자료구조에 대한 이해는 컴퓨터과학의 기본원리에 대한 기초단계교육이라 할 수 있다. 그러나 자료구조가 정보교과에서 갖고 있는 교육적 함의나 학생들에게 성찰을 제공하기 위해 어떤 형태로 구성되어야 하는지에 대한 연구는 이루어지지 않았다. 따라서 본 논문은 2007 개정 교육과정을 기초로 제작되어, 2010년부터 사용되고 있는 정보교과서 '정보의 표현과 관리'영역의 탐구적 경향을 분석하였다. Romey 분석법으로 분석한 결과, 본문 분석, 학습자료 분석, 학습활동 분석, 장이나 절에 대한 분석에서 탐구적 경향을 보인 교과서는 1개로 나타났다. 교과서가 지식을 전달하는 데 집중하면, 학생들을 학습에서 소외시킬 수 있다. 특히 정보교과의 경우, IT를 활용한 문제해결에 기저가 되는 교과이므로 학습에서 소외된 학생들은 다양한 문제해결의 과정에서 박탈될 수 있음을 고려해야 한다는 시사점을 제공하였다.

A concrete floor trowel machine, developed in the U.S in 1990's, consists of only two rotary trowels, and doesn't need any other mechanism for motion such as wheels. When the machine flattens a concrete floor with its rotary trowels, the machine can move in any direction by utilizing the unbalanced friction forces occurring between the rotary wheels and the floor when the trowels are tilted in appropriate directions. In order to automate the trowels machine, this paper proposed the self-propulsive concrete finishing trowel robot which has twin trowels. For the control of the robot, this paper discussed the following. Firstly, the dynamics model of the driving frictional force applied on each trowel from the floor is derived. Secondly, the relationship between the driving force for the robot and the control variable of the robot is derived. Finally, the basic motion of the robot are realized by using the obtained relationship. This paper figures out how the concrete floor finishing robot with tow trowels moves and will contribute to realizing it.

The under-registration of water meters of 20mm to 50mm in diameter, installed in Seoul city, was estimated by random sample method. The sample sites and sampled meters were selected for the measurements of flow rates and accuracy tests, respectively. The measurement of flow rates was conducted for 20mm to 50mm meters for about 20 days per site using flow meters and data loggers. The under-registration of 20mm, 25mm, 32mm, 40mm, and 50mm meters was observed as 3.96%, 1.10%, 2.47%, 4.04%, and 1.04%, respectively. The under-registration might be increased more or less as malfunction and failure of the sampled meters was not considered. In this study the under-registration of 20mm, 25mm, 32mm, 40mm, and 50mm meters was accurately estimated on the basis of the investigation data. The estimation of under-registration of water meters, one of the basic figures in water industry, contributed to accurate calculation of leakage, water supply and consumption, and strategic planning to reduce the unaccounted-for water.
