사립박물관의 조사연구 활동의 실태와 개선방안

김동선 한국박물관학회 2008 博物館學報 Vol.- No.14·15

사립박물관은 기업체 및 뜻이 있는 개인이 유물을 수집 박물관으로서 명맥을 유지해오다 1993년에 와서야 박물관 · 미술관 진홍법이 공포된 후 같은 해 같은 날에 30여개의 박물관이 인가를 받아 문화관광부에 등록하게 된 후 현재는 200여개의 박물관이 개관하게 되었다. 성격은 대부분 테마박물관으로 한 가지 테마를 중심으로 우리의 역사와 문화, 과학을 조명해 볼 수 있는 박물관으로 운영되고 있다. 박물관은 유물을 수집 , 보존, 전시 연구, 교육의 기능 중에서 조사연구 활동은 박물관을 진 홍 · 발전시키는데 가장 중요한 핵심요소임에도 설립자들이 유물만 수집되면 박물관을 설립하 겠다는 의욕이 앞서 박물관을 개관하다 보니 박물관의 운영의 어려움에 부딪쳐 소수의 박물관 은 폐관위기 에 놓여 있는 현실이다.

한국 남동 연안역의 용승현상에 관한 수치실험

김동선,김대현,Kim, Dong-Sun,Kim, Dae-Hyun 해양환경안전학회 2008 해양환경안전학회지 Vol.14 No.1

1999년 6월 한국 남동 연안역의 울산과 감포 앞바다에 출현한 용승에 의한 냉수출현현상을 3차원 진단 수치모델을 이용하여 조사하였다. 수치실험에 의한 냉수출현은 바람 영향으로 인하여 울산-감포 앞바다의 수심 50-100m 층에서 발생한 상승류의 효과로 나타났다. 이러한 용승현상은 인접한 부산, 울산 및 감포에서 관측한 바람의 2배인 5.0/m/sec 크기의 바람을 모델에 적용했을 때 발생했다. 따라서 용승현상과 같은 특이한 해양현상을 규명하기 위해서는 육지에서 관측한 자료가 아닌 그 해역에 적절한 바람자료를 이용해야 한다.

To investigate major factors controlling variations in water quality, principal component analysis and cluster analysis were used to analyze data sets of 12 parameters measured at 23 sampling stations of Jinhae Bay during winter and spring. Principal component analysis extracted three major factors controlling variations of water quality during winter and spring. In winter, major factors included freshwater input, polluted material input, and biological activity. Whereas in spring they were polluted material input, freshwater input, and suspended material input. The most distinct difference in the controlling factors between winter and spring was that the freshwater input was more important than the polluted material input in winter, but the polluted material input was more important than the freshwater input in spring. Cluster analysis grouped 23 sampling stations into four clusters in winter and five clusters in spring respectively. In winter, the four clusters were A (station 5), B (stations 1, 2), C (station 4), and D (the remaining stations). In spring, the five clusters included A (station 5), B (station 1), C (station 3), D (station 6), and E (the remaining stations). Intensive management of the water quality of Masan and Hangam bays could improve the water quality of Jinhae Bay since the polluted materials were mainly introduced into Jinhae Bay through Masan and Hangam bays.

인공용승구조물 설치해역의 해양환경 특성

To investigate the variation of marine environments due to set up of artificial structure, we carried out field observations. High temperature and salinity waters near the south frontal area were distributed clearly in the southeastern part of study area during summer season The variation of current structure was also occurred around study area where artificial structure set up. In 2005 after set up of artificial structure, the nutrient concentration increased greater than that in 2002 before set up artificial structures. To illustrate the characteristics of marine environment due to set up of artificial structure, quantitative analyses on the effect of artificial structure are important.

In order to estimate the characteristics of water movements around artificial upwelling structure, current measurements were carried out along lines E-W and S-N on May 4th(neap tide} and May 30th(spring tide), 2006. In the study area, southeastward flow was dominant during the field observations, and the pattern of water movement in the upper layer above 30m depth was different from that in the lower layer below 30m depth Vertical flow(w-component} around the artificial structure area and western area was shown to be upward flow, but downward flow occurred in the southern, northern and eastern parts at the neap tide. At the spring tide, the ebb current along E-W line showed upwelling flow in the eastern part and western area and showed upwelling flow near the artificial structure area and downwelling flow far away that one. At the spring tide, upward flow was dominant along S-N line during the flood current Volume transport by upward flow was higher than that by downward flow. Volume transport by upward flow during ebb of neap tide was greater than during flood current of neap tide, but was reverse at the spring tide.

Objectives : This study was performed to find best extraction solvent for application of Ulmi cortex to food or herbal medicine as an antioxidant only using water, ethanol and their mixtures. Methods : The Ulmi cortex extracts were prepared using water and 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% and 100% (v/v) ethanol, and were evaluated yields, total polyphenol contents, DPPH and ABTS radical scavenging activities, lipid peroxidation activities, and catechin and epicatechin contents. Results : Among the Ulmi cortex extracts, the yield was highest in water extract (8.9%) and lowest in ethanol extract (3.8%). The yield of 30% ethanol extract (8.5%) also was very high to similar with water extract. The total polyphenol content was highest in the 30% ethanol extract (253.6 μg /mg extract) and lowest in water extract (109.0 μg /mg extract). The DPPH radical scavenging activity was highest in ethanol extract (IC50, 8.53 μg/ml), ABTS radical scavenging activity was highest in 60% ethanol extract (IC50, 3.08 μg/ml), and the inhibition of lipid peroxidation was highest in 70% ethanol extract (IC50, 7.96 μg/ml). As ethanol content of extraction solvent increased from 0% to 30%, the antioxidant activities were remarkably increased whereas from 30% to 100%, the antioxidant activities were increased or decreased a little. Conclusions : The findings of the present study suggest that 30% ethanol is best solvent for extraction of Ulmi cortex, considering yield, polyphenol content, and antioxidant activities with extraction cost.
