  • In this paper, the aim is to develop plasma heater products combining the sterilization and purification functions of low-temperature plasma lamp method with the function of vertical heating system using wavelengths of vacuum magnetic (VU). Through this process, the government aims to improve the cultivation environment of crops in greenhouses or facility houses and to increase their storage capacity by increasing the freshness of stored crops such as free-temperature storage. In addition, real-time monitoring technologies will be incorporated that will enable users to identify and respond to changes within greenhouses in real time by utilizing ICT technologies.

  • Ten taxa of green algae collected at 8 stations of reservoirs and one of aerial habitat were reported newly in Korea. They belong to 7 genera, 2 species, 6 varieties and 2 forms and include one taxon of Scenedesmus, Actinotaenium, Euastrum, Hyalotheca, Staurastrum and Teilingia respectively, 4 taxa of Cosmarium. The Korean green algae, including these newly reported ones, totals to 1,131 taxa, and classified as 1 class, 10 orders, 34 families, 140 genera, 728 species, 318 varieties and 85 forms. Actinotaenium cucurbita var. cucurbita f. rotundatum cultured in this study was appeared to be variable in the size of isthmus. In the Korean taxa of Cosmarium lapponicum var. granulatum, C. portianum var. orthostichum and Euastrum denticulatum var. rectangulare, cell sizes were shown smaller than previously reported ones. Five taxa including Cosmarium lapponicum var. granulatum were occurred in the eutrophic states, and Cosmarium decedens, previously reported as present in the freshwater area, was collected at the aerial habitat in this study.

  • Six taxa of unrecorded Korean species of genus Cosmarium were collected from several freshwater sites of South Korea in 2003. They were 3 species and 3 varieties of Genus Cosmarium. Genus Cosmarium of Korea was reported to totally 273 taxa 125 species, 113 varieties and 35 forms including this study.

  • Microbiological quality of packaged meals (Dosirak) was assessed in three operations under the both conditions of actual food processing and simulated time-temperature. Time and temperature data indicated that all the phases after cooking were critical for microbiological quality control. Microbiological test results by simulated time-temperature conditions revealed that microbiological quality of packaged meals decreased as the storage time and temperature increase. Delivery practices without refrigeration in summer and hot-holding below $60^{\circ}C$ in supermarket were crucial in microbiological quality control.

A Phylogenetic Study of Staurastrum Complex (Chlorophyta) Inferred from coxIII Sequence Analysis (coxIII 유전자 염기서열 분석에 의한 팔장고말 COMPLEX(녹조식물문)의 계통 연구)

  • The intergeneric relationship of Staurastrum complex including genus Arthrodesmus and Xanthidium was studied on the basis of mitochondrial coxⅢ sequence variation. Teiling's suggestion that Staurodesmus was an independent genus apart from genus Staurastrum, Arthrodesmus and Cosmarium was also reevaluated. The phylogeny inferred from coxⅢ gene was not consistent with morphological characteristics of Staurastrum complex. Genus Staurastrum was closely related to genus Xanthidium in the phylogenetic analysis of coxⅢ, but distant to genus Staurodesmus. The taxonomic treatment of genus Staurodesmus as an independent entity could not be determined, because Staurodesmus did not firm a monophyletic Glade. Therefore, genus Staurodesmus could not be treated as an independent genus as Prescott et al. (1982) claimed.

  • 언어를 구사하는 능력은 연령별, 개인별로 차이가 있다. 이 능력은 평가 분류에 따라 수치적으로 평가될 수 있다. 그러나 수치로 평가하는 것 보다 비슷한 연령의 평균적인 능력과 비교를 통하여 능력을 평가하는 것이 일반적이다. 언어 병리학에서 평가를 하는 보편적인 방법은 언어 병리 전문가가 하는 것이다. 그러나 사람을 통한 평가 방법은 시간과 비용이 많이 소요될 뿐만 아니라 객관적이지 못한 평가라 할 수 있다. 따라서 이번 연구에서는 한국어 발화에 대한 분석을 자동화 하는 시스템을 제안한다.
