  • 천연기념물 제395호 진주 가진리 새발자국과 공룡발자국 화석산지는 1997년 5월 20일, 경남과학교육원 신축 공사장에서 당시 경남과학고등학교 교사로 근무하던 백광석(현재 서상중고등학교 교장)에 의해 최초로 발견되어, 수 백 점의 새발자국 화석과 공룡발자국 화석들이 학계에 알려지게 되었다. 지금까지도 세계 여러나라의 중생대 새 발자국 중에서 가장 밀도가 높은 화석산지로 손꼽히고 있으며 많은 학자들의 관심을 받고 있다. 이곳의 지질은 백악기 하양층군 함안층 하부의 적색 이암 또는 셰일과 사암의 호층으로 구성되어 있고, 새발자국 화석들은 적색 이암에서 발견된다. 현재, 이 화석산지는 경남과학교육원 건물 내부에 위치하고 있으며, '화석문화재전시관'이라는 명칭으로 보호 및 관리되고 있기때문에 자연재해와 풍화에 의한 침식을 1차적으로 막고 있다. 이 화석산지는 우리나라에서는 천연기념물 제394호 해남 우항리 화석산지와 함께 현장을 그대로 보존하면서 화석의 보존과 관리를 동시에 할 수 있는 건물을 지어 자연사교육을 진행할 수 있는 곳으로 많은 학생들을 대상으로 우리나라의 소중한 화석을 직접 관찰하고 학습하는 체험교육이 가능하다. 원격조종카메라 시스템을 활용하여 관람객이 직접 자신이 원하는 발자국 화석을 세부적으로 관찰할 수 있게 장치한 interactive system은 과학교육 효과를 증진시킨다. 선행 연구에 의하면, 본 화석산지에서 익룡의 발자국 화석(KS 071)도 공룡이나 새발자국과 같은 층리면에서 서로 겹쳐서 나타난다고 보고되었으나, 본 연구에 의해 다시 조사된 결과 전형적인 익룡의 발자국 화석에서 보이는 분명한 특징들을 발견할 수 없었다. 물갈퀴를 가진 새발자국 가운데에서 Uhangrichnus chuni 와 Jindongornipes kimi 로 기재된 표본들에 대하여서도 새롭게 분석하였다. Uhangrichnus chuni로 기재된 많은 표본들은 II-IV번 발가락 사이의 각, 물갈퀴의 형태, 뚜렷한 hallux 등의 형태적 특징을 근거로 할 때, 대부분이 Ignotorinis yangi로 판단된다. Jindongornipes kimi로 기재된 표본들은 이미 기재된 표본보다 크기가 적어도 10%-25%가 작으며, II-IV번 발가락 사이의 각에서 차이를 보인다.

  • This study was conducted to select the cultivars and strains which are suitable in cultivation of the Chinese cabbage having good horticultural characteristics and the resistance to clubroot caused by Plasmodiophora brassicae, which is a widespread disease that causes serious problems in many Brassica growing areas. Thirty four cultivars and nineteen strains of the Chinese cabbage were planted in the contaminated fields in highland and investigated the wilting symptom due to the initial disease occurrence and high temperature. Disease occurrence rate and severity of clubroot and the horticultural characteristics were also examined. According to the results, Bulamplus, Kangryeokyeoleumbaechu among cultivars of Chinese cabbage, SP-05, SP-02, CR DB 50, and CR DB 29 among strains of Chinese cabbage were resistant to hot weather by showing delayed above-ground symptom (wilting) of clubroot in 30 days after transplanting. In case of below-ground clubroot rate, Daetong, super CR Kimi 85 and super CR Hiroki among the cultivars of Chinese cabbage were resistant to clubroot in 60 days after transplanting. When fresh weight of Chinese cabbage among cultivars were compared, super CR Hiroki of over 2,500 g was the highest among other cultivars. Although the resistant and susceptible reactions of Chinese cabbage cultivars and strains against clubroot disease were somewhat different from the above-ground symptoms (wilting) of clubroot in 30 days and below-ground symptoms of clubroot in 60 days, we recommend that super CR Hiroki, CR Kimi 85, CR Janggun among cultivars of Chinese cabbage and CR DB 50 and CR DB 29 among strains of Chinese cabbage will be more suitable in cultivation of Chinese cabbage in highland.

  • In this paper, cardiac parameters and relationship between stroke volume and impedance change were explained, and an impedance cardiograph was designed and constructed, and its accuracy was verified by experiment. Useful cardiac parameters such as stroke volume and contractility of cardiac muscle were measured noninvasively. The reproducibility of the instrument was measured to be better(less than 10%) than that of clinical standard method such as thermodilution. Hence impedance cardiography was found to be better technique for monitoring stroke volume and contractility of patients for pre and post operation, and pharmacological studies.

  • 최근 경기침체에 다른 여파로 중소기업의 경기동향은 나날이 악화되고 있는 추세이다. 소비심리 위축과 수출 여건 악화로 부도율이 높아지고, 향후 경기전망도 불투명해 기업경영에 이 중고를 겪고 있다. 그러나 전반적으로 중소기업의 경기동향이 좋지 않은 상황에서 정보화 수준에 따라 업종별로 가동률, 생산지수를 비교한 결과 정보화 수준이 높은 업종이 여타 업종에 비해 상대적으로 경기침체의 영향을 적게 받은 것으로 나타났다. 실제로 정보화 수준이 중소기업의 경영성과에 어떤 영향을 미치는지를 알아보기 위해 3가지 실증분석 모형을 통해 분석해본 결과, 1인당 매출액, 총매출액, 개인업무개선, 기업업무개선, 조직의 유연성, 대외환경 적응력 등 기업 내외부 전반에 걸쳐 유의적으로 긍정적인 영향을 미치는 것으로 나타났다. 즉, 정보화 수준 향상이 기업 경쟁력에 미치는 효과가 크므로 생산성 향상을 통해 경기침체기를 극복하기 위해서라도 경기 호황기는 물론 불황기에도 정보화 투자에 소홀히 하면 안된다는 것을 보여준다.

  • The Cretaceous Gyeongsang Supergroup, composed of clastic sediments mostly deposited in the lacustrine and fluvial environment, is widely distributed in the southern part of the Korean Peninsula. Diverse fossils of plants, molluscs, insects, footprints of dinosaurs, pterosaurs and birds, and eggs, bones, and teeth of dinosaurs have been found from the Gyeongsang Supergroup. New types of dinosaur, pterosaur, and bird tracks recently discovered from the Gyeongsang Supergroup attract great attention from the world. Several tracksites of dinosaurs and birds were designated as Natural Monument and nationally conserved, and many efforts have given to them for nomination of UNESCO World Heritage. Bird tracks from the Gyeonsang Supergroup are Koreanaornis hamanensis, Jindongornipes kimi, Goseongornipes markjonesi, Ignotornis yangi, Uhangrichnus chuni, and Hwangsanipes choughi, which correspond approximately one third of Mesozoic bird tracks recorded from the world. The Gyeongsang Basin of the Korean Peninsula yields world most diverse bird tracks which may be called a paradise of Mesozoic birds and they are important natural heritage providing significant information about evolution and paleogeographic distribution of birds.

  • The goal of this study is to elucidate the fusulinid biostratigraphy of the Carboniferous limestones distributed in the Gangdong area of Samcheok coalfield, Korea. The Carboniferous strata of the study area mainly comprise alternaton of dark gray shale, dark gray and reddish sandstone, and gray limestone. The limestones consist mainly of wackestonepackstone containing various fossil fragments such as crinoid, coral, brachiopod, foraminifera, fusulinid, and bryozoa; this observation thus suggests that the study site was the shallow marine environments. A tital of 12 species belonging to 5 genera of fusulinids are identified from the limestones of the Gangdong geologic section: Ozawainella turgida Sheng, Ozawainella sp. A, Ozawainella magna Sheng, Pseudostaffella antiqua (Dutkevich), Pseudostaffella paracompressa Safonova, Pseudostaffella kimi Cheong, Pseudostaffella sp., Beedeina lanceolata (Lee and Chen), Beedeina samarica (Rauser-Chernoussova), Beedeina sp. A, Neostaffella sphaeroidea cuboides Rauser-Chernoussova, and Hanostaffella hanensis Cheong. Such fusulinids species were reported from the lower part of the Geumcheon Formation in Samcheok coalfield and the middle Moscovian stage in Eurasia. On the basis of the fusulinid biostratigraphic correlation of the Gangdong geologic sections (A) to (C), the limestone should be overlapped by faults and folds. Moreover the stratigraphic thickness of the limestone is thinner than the thickness of the limestone outcrop of the Gangdong geologic section. Therefore, the stratigraphic sequence of the Gangdong geologic section is represented as the Gangdong geologic section (A).

  • In this study, a species of Rhabdocoela is reported from Korea for the first time. The kalyptorhynch Alcha sinensis Wang & Hu, 2019, was collected from the intertidal zone of Anmyeon Island. Compared to the original study on A. sinensis and previous studies on A. evelinae, we provide additional detail of these two species through pictures of the stylet and a improved description of the prostate stylet type III, which is composed of a bowtie-shaped base and two pairs of heteromorphic plates with fringed or serrated edges. Two plates are also provided with a rounded "blade". Also, we discuss the importance of the prostate stylet type III as a diagnostic character. After a thorough comparison of the descriptions of A. evelinae Marcus, 1949, and A. sinensis, we conclude that the Korean specimens belong to the latter species. Finally, we discuss the difficulties of interpreting diagnostic characters of the small and complex prostate stylet type III within the genus Alcha.

  • The purpose of this case study is to suggest the indicators of an informatization maturity level and critical success factors in small and medium automotive parts manufacturers. To achieve this goal, literature reviews and case studies on 7 automotive parts manufacturers that confirmed to implement information systems successfully, were conducted. Based on literature review, the six functional processes including development, production scheduling, purchase, production, order, and support process, were defined. Each process has 5 levels from 1(low level) to 5(high level) depending on the degree of informatization maturity. In addition, critical success factors were discovered with interviews of CEO or CIO. The results of this study can be applied to any companies which are implementing or intended to the information systems near future.
