The flora of Mt. Taebong area, located in Cheonan city, Chungcheognam-do, Korea, was investigated from 9 May 2003 to 4 October 2003. As a result, the flora was consisted of 83 families, 298 genera and 337 taxa. Among them, 179 taxa(53.4%) were belonged to 9 families, and Composite and Gramineae were the biggest two groups. Endemic plants in Korea were 6 taxa, specific plants ware 13 taxa, rare and endangered plants were 2 taxa, naturalized plants were 17 taxa in this area. This area according to the distributional at pattern of korean vascular plants belonged to Middle province. Analysis tables were made to know the distributional, morphological, phenological and practical characteristics of the flora. Modal characteristics of the flora were: climbing plants(22 taxa), herb(252 taxa), and wood(85 taxa). Among vascular plants of this area, deadly poison plants were 2 taxa, mediocre poison plants ones 18 taxa and mild poison plants ones 8 taxa. Among vascular plants of this area, edible sources were 179 taxa, medical ones 263 taxa, industrial ones 23 taxa, fiber ones 23 taxa, fodder ones 10 taxa, green manure ones 2 taxa, oil ones 6 taxa, fragrant ones 72 taxa and dye ones 33 taxa

나성태,최홍근,김영동,신현철 한국식물분류학회 2008 식물 분류학회지 Vol.38 No.2

Taxonomic identities of Utricularia japonica and U. tenuicaulis were examined. Utricularia japonica was differed from U. tenuicaulis by having a scape narrower than the stem, rather sparsely arranged leaves, and more or less oblong leaves. Utricularia japonica has been known to occur widely in Korea due to the misidentification of U. tenuicaulis, which is distributed widely in southern and middle Korea. However, only one population of U. japonica was found in Chunjin Lake, near Kosung-gun, Kwangwon-Do, in Korea. 한국산 통발속 식물중 수생형인 통발(Utricularia japonica)과 참통발(U. tenuicaulis)의 분류학적 실체를 파악하였다. 통발은 참통발에 비해 화경이 줄기보다 좁으며, 잎의 배열이 다소 빽빽하고, 잎의 형태가 약간 타원형 구조를 하고 있어 구분된다. 지금까지 국내에서 통발로 알려진 통발속 분류군은 참통발의 오동정으로 파악되었으며, 통발은 강원도 천진호에서만 그 분포가 확인되었다.

The purpose of this paper is to find out the effects on the student’s preferences and attitudes for mathematics when ICT(Information and Communication Technology) is applied to the teaching of mathematics. 8th grade students (a1together 62 students) were divided into two groups. To one group of students(31 students), lectures were given using only the traditional methods and to another group of students(31 students) lectures were given with the ICT. Results showed that the teaching of mathematics with the help of ICT had positive effects on the student’s preferences and attitudes for mathematics and cognitive area. Especially ICT had an opportunity for the students to get a good chance to study hard mathematics with ease and for teachers to teach the students mathematics with fun. If there is unsettled subjects left, one is for the students to get a positive attitude in learning. The other is for the educational institute to give them places and various softwares. ln addition, the research for the improvements of educational environment should be provided.

An investigation was conducted on the water environmental factors at five sites in summer of the Namyangho from 29 May to 31 August 2003. As result, the water temperature was ranged 21.0-25.9℃, highest at site 5 in upsteam. The value of pH was stabilized, its was ranged 8.01-10.27. The dissolved oxygen(DO) was ranged 4.72-15.82 ㎎/l. The turbidity was ranged 13-64 NTU. The conductivity and salinity were 0.148-1.050 ㎳/㎝ and 0.00-0.04%, respectively. The conductivity and salinity were highest in 29 May and revealed similar pattern, also closely related to between.

The flora was composed of 46 families,105 genera, and 136 taxa. Among them, the hydrophytes were confirmed as 29 taxa(21.3%), hygrophytes were 32 taxa(23.5), and terrestrial plants were 75 taxa(55.1%). Hydrophytes were composed of 15 taxa emergent hydrophytes, 5 taxa submerged hydrophytes, 4 taxa floating-leaved hydrophytes, and 3 taxa emergent hydrophytes. The dominant hydrophytes were Phragmites communis Trin. and Zizania latifolia Turcz.. The rare plants of Hydrocharis dubia (Blume) Backer, Rorippa globosa Thell., Trapella sinensis var. antennifera Hara., and Wolffia arrhiza (L.) Wimmer were colledted in these area.

팔당호 연안대의 수생식물상과 식생을 파악하기 위하여 2003년 4월부터 2004년 4월까지 9곳의 조사 지점을 선정하여 선방형구법을 이용하여 조사하였다. 팔당호 연안대에는 128종류의 관속식물이 생육하고 있는 것으로 조사되었고, 이중 수생식물은 38종류였다. 수생식물의 경우 정수식물이 21종류로 가장 많았고, 침수식물은 8종류 였고, 침수식물 종류수는 이전 조사보다 감소한 것으로 파악되었다. 팔당호 주요 식생은 애기부들, 줄, 갈대가 우점하는 정수식물대로 파악되었고, 특히 두물머리, 광동교 근처에 넓게 정수식물대가 넓게 발달하였다. 귀화식물은 11종류가 분포하고 있었으나, 출현 빈도는 상대적으로 높았다. 팔당호 연안대에 분포하는 식물의 출현 빈도를 조사 지점을 기준으로 살펴보면, 조사 지점당 수생식물은 2.7종류, 습생식물은 2.5종류, 육지식물은 1.8종류로 파악 되었고, 수직대상분포 식생이 팔당호 연안대에서 발견되었다. 이러한 조사 결과는 팔당호 연안대가 수생태계의 전형적인 특성들을 지니고 있는 것으로 풀이된다. To investigate the flora and vegetation structure of vascular plants in the littoral zone of Paldang Reservoir, from April, 2003 to April 2004, nine sampling sites were selected. Along the Paldang Reservoir, 128 taxa, consisted of 51 families and 96 genera, were identified, among them, hydrophytes were confirmed as 38 taxa, which was comprised 29.7% to total taxa, whereas hygrophytes were 44 taxa and terrestrial plants were 46 taxa. Emergent hydrophytes consists of 21 taxa, including Phragmites australis and Typha angustifolia, and next, submerged hydrophytes were 8 taxa. However, the kinds and vegetation area of submerged hydorphytes were reduced compared to previous studies. In the littoral zone of Paldang Reservoir, the aquatic vegetation was widely developed near Dumulmori, Yangsuri, and Kwangdong Bridge, downstream of Kyungancheon. The average number of hydrophyte per sampling sites were 2.7 taxa, whereas hygrophytes were 2.5, and land plants were 1.8. In addition, the hydrophytes in the littoral zone of Paldang Reservoir showed the typical vertical zonation pattern like a natural swamp. These results mean that the littoral zone of Paldang Reservoir has the typical characteristics of aquatic plant ecosystem.

In general, since the types and types of ships, so complex and various variables are included to measure the amount of construction work. In addition, it is mot easy to predict the schedule or the number of working hours before ship construction, and it is also mostly inaccurate. As a result, the master plan is manually drawn up by the expert's experience, but there are limitations due to various factors. Medium and large shipyards are operating APS(Advanced Planning and Scheduling) system that reflects industrial characteristics to improve productivity in the planning stage, and utilize information from systems such as ERP(Enterprise Resource Planning) system and MES(Manufacturing Execution System). On the other hand, small shipyards rely mostly on manual work such as Excel work based on the experience of the workers. Therefore, this study intends to develop a master plan management system that can efficiently manage the production process from the business planning stage in consideration of the characteristics of small shipyards.
