This study was carried out to investigate the flora of the southeastern areas, including Donghae-si and Samcheok-si, of Gangwon-do. Vascular plants based on voucher specimens were summarized as 750 taxa, including 109 families, 394 genera, 642 species, 5 subspecies, 90 varieties, and 13 forms. Among the investigated 750 taxa, 17 Korean endemic, 38 rare plants and 147 specially designated plants by the Ministry of the Environment were also included. The naturalized plants were 28 taxa, and the percent of naturalized plant species was estimated as 3.7%. The life form of the investigated taxa was the H-R5-D4-e type. The usefulness of the plants of the 750 taxa listed consists of 284 taxa (37.9%) of edible plants, 232 taxa (30.9%) of medicinal plants, 124 taxa (16.5%) of pasture plants, 88 taxa (11.7%) of ornamental plants, 21 taxa (2.8%) of timber plants, 20 taxa (2.7%) of fiber plants, 7 taxa (0.9%) of miscellaneous plants and 3 taxa (0.4%) of industrial plants.

Antioxidant activity and related components including tocopherols, phenolic compounds and carotenoids in the corn(Zea mays L.) kernels were measured to understand effects of fertilizer application. Hybrids used were Chalok 2, a waxy corn, and Suwon 19, a dent corn. The standard fertilizer level of N-P-K was 14.5-3-6 for Chalok 2 and 17.4-3-6.9 for Suwon 19. The treatments of the fertilizer levels were the standard level, half and two fold amounts of N, P, and K, and no fertilizer. The antioxidant activity was determined by measuring electron donating ability. The antioxidant activity of Chalok 2 was higher than Suwon 19. The antioxidant activity was the highest at the standard fertilizer treatment for Chalok 2, but was statistically not significant. The antioxidant activity and the related compounds content in Suwon 19, however, were the highest in the two fold nitrogen treatment, and the differences were significant. The contents of tocopherols, phenolic compounds and carotenoids were 30.0~38.1, 104.7~118.8, $0.1{\mu}gml^{-1}$, respectively for Chalok 2 and 16.7~20.1, 59.9~72.7, $35.5{\sim}50.0{\mu}gml^{-1}$, respectively for Suwon 19. The antioxidant activity was positively correlated with the grain yield in both cultivars. The shorter the ASI the higher the yield of the plant. The difference in genetic factors would affect greater influence than fertilizer effect on the antioxidant activity of corn.

This is the first study in Musicology that discusses the features of Kangwon Sangkangrye(the pre-lecture ritual in Buddhism). In this thesis, I reviewed and compared the similarity and uniqueness between Kangwon Sangkangrye in "Seokmunuibom" and the one being performed these days. The musical relation between the performance shown in the historical record and the one in contemporary ritual was illustrated here based on the findings derived from the anlaysis on its bell(小鐘) performance. The analysis made upon musical sources recorded on-site shows the characteristics of contemporary Kangwon Sangkangrye. Following is a brief summary of this study. The review and comparison between Kangwon Sangkangrae in "Seokmunuibom" and the one being performed these days showed that the second type, which was significantly different from the first type, was closer to that of the historical record. The performers at Unmunsa Temple and Chungamsa Temple seemed to be following the tradition bell(小鐘) performance style which was found in the text of the historical record. Through the analysis on Kangwon Sangkangrae, I found that it has musical characteristics as follows. The vocal range of type 1 and type 2 was mostly performed within Minor 7th and didn't exceed the perfect 8th. The melodic structure of type 1 starts with do'-la of naedeureum and ended with the melody which downscaled from do' and finalized from mi to la. Usually the mode was in menari-tori but at some lecture halls a few cases found to be upscaled from sol to la which differentiates it from the typical menari-tori of folk songs. Like the typical way of traditional rites, the singing was divided into two parts: the leading call and the following choral response. Most were sung to be one syllable on one or two tones or one syllable lasting for several tones and the musical forms were varied by musical pieces. Meantime, Sangkangrae at Haeinsa Temple was differed from that of the other temples in terms of ritual procedure and vocal style. It added Korean version of and the lead vocal skipped the first phrase of the Sasul. The melodic structure of Type 2 started with do'-la of naedeureum and was finalized as the same way of Type 1. The mode of was not the same as typical menari-tori but the Jeongrye(prostration) and Balweon(a great vow) were identical to the menari-tori of folk songs. The singing was done in two forms, solo and unison, and the lyric-attachment of Gesong was one syllable for one or two tones and that of Jeongrye and Balweon were one syllable for one or two tones + one syllable for several tones. The musical form of Jeongrye is A-B-C and A-C. Balweon didn't display a certain periodicity but still maintained sense of unity and formality through repetition of the finalizing melody.

This study estimates how much climate variables affect the land price and acreage of rice paddy and dry farm field in agriculture with the case of Gangwon-do in Korea. To this end, we capitalize upon the Ricardian approach based upon the panel data on climate, soil and geography, farmland prices and acreage, other economic and social variables for 11 municipal units comprising Gangwon-do during the period of 1992-2010. Our empirical analysis shows that the temperature variable has negative economic impacts on the price and acreage of rice paddy and dry farm field, confirming that the temperature variable is much significant than that of precipitation in global warming. On the other hand, the other determinants of farmland price and acreage are different with the type of farmland in Gangwon-do.

광섬유 Fabry-Perot 간섭계를 센서로 하는 TDM 다중화 광섬유 압력/온도 센서시스템을 개발하고, 이 시스템을 이용하여 수위와 온도 측정실험을 행하였다. 측정시스템의 측정속도는 측정데이타를 저장하지 않는 경우 최대 초당 4500회이며, 센서의 응답속도는 ~1 ms로 추정된다. 압력센서와 온도센서의 특성은 이론적 추정치와 비교하여 각각 +13.7%,-18%의 차이를 보였으며, 반복실험을 통하여 선형화한 후의 선형화 오차는 1%이내, 온도의 변화가 0.1$^{\circ}C$이내 일 때 수위측정의 오차는 $\pm$0.3cm이며, 수위측정에 대한 시스템 잡음은 측정하지 않았다. 온도센서의 시스템 잡음은 0.1$^{\circ}C$이내였으며, 이 시스템을 이용하여 수위 및 온도 변화량에 대한 고속 측정실험을 수행할 결과 예상된 결과를 얻을 수 있었다.

지리학적으로 고립된 지역에서 발생하는 산불과 같은 자연재해는 네트워크 설치의 어려움으로 외부에 빠르게 알려지기 어렵다. 본 연구에서는 infestation 모델을 응용하여 기존 네트워크에서 단절된 지역에서 발생할 수 있는 자연재해를 빠르고 효과적으로 전달할 수 있는 bio-ad hoc 모델을 설계하고자 한다. Infestation이란 기존 네트워크 infrastructure와 연결된 정보기지로서, 각 노드가 좁은 대신 빠른 대역폭을 가지는 infostation의 통신가능 반경에 인접했을 때 고속데이터 전송이 가능하게 설계한 통신 모델이다. 본 연구에서는 동물에게 이식된 센서로부터 데이터를 생성하고, 각 동물들에게 무선 태그를 설치하여 그 데이터를 효율적으로 목적지까지 전송수 있는 모델을 설계하기 위하여 infestation에 도달하기 전의 데이터가 각 노드사이에서 서로 공유될 수 있는 sparse ad-hoc infostation model을 제안하였다. 이 모델의 가능성을 알아보기 위해 동물의 최대 속도를 이용하여 동물의 이동성 및 체류시간을 결정한 후에 동물의 수 및 infostation의 수에 따른 도달시간을 시뮬레이션하였다.

The purpose of this study was to understand the geographical and environmental distribution of wild animals in Baekdudaegan region using field survey and GIS data. Crucial factors were selected and analyzed to understand the distributional characteristics of wild animals (7 species in 6 families) and rare endemic plants (14 species in 11 families). These crucial factors include stand factors (forest type, DBH class, and crown density), soil factors (bed rock, soil texture, and organic matter), geographical factors (elevation, slope, aspect) and climatic factors (temperature, rain fall, humidity). Finally, 10 factors were selected by statistical analysis and categorized for analyzing geographical and environmental features. Four families such as Muridae, Sciuridae, Suidae and Talpidea in wild animal showed the similar habitat characteristics with the 10 factors.

A series of wind tunnel tests was conducted to investigate the existence of the galloping instability of inclined dry cables and also to Identify the influence of some parameters on it. These parameters are the structural damping and cable surface roughness, which may have significant impact on the vibration characteristics. The test results showed both the divergent type of galloping instability and the limited amplitude high wind speed vortex shedding excitation. Galloping instability was observed in only one case. Parametric study shows that the vortex shedding oscillation can be easily suppressed with an increase of structural damping. It was also shown that the instability criterion indicated by earlier research was too conservative compared to the results obtained from the present study.
