The numbers of vascular plants were summarized as 604 taxa including 107 families, 343 genera, 530 species, 5 subspecies, 58 varieties and 11 forms. The rare plants were 12 taxa including Paeonia japonica (VU), Syringa patula var. kamibayshii (LC), Cynanchum inamoenum (VU), Schpolia japonica (LC), Scrophularia koraiensis (DD) and so on. The Korean endemic plants were 16 taxa including Pseudostellaria coreana, Clematis trichotoma, Stewartia pseudocamellia, Ajuga spectabilis, Cirsium setidens and so on. In the specific plants by floristic region were 60 taxa, a degree I were 29 taxa (Sisymbrium leteum, Ilex macropoda, Eleutherococcus sessiliflorus, Cirsium pendulum, Veratrum versicolor and so on), 21 taxa of a degree II (Morus cathayana, Phellodendron amurense, Euonymus pauciflorus, Angelica tenuissima, Heloniopsis koreana and so on), 8 taxa of a degree III (Rhynchosia acuminatifolia, Stewartia pseudocamellia, Cynanchum inamoenum, Schpolia japonica, Scrophularia koraiensis and so on), Wisteria floribunda (Planted) of a degree IV and Prunus yedoensis (Planted) of a degree V. The naturalized plants were 42 taxa including Phytolacca americana, Solanum carolinense, Ambrosia artemisiifolia, Aster pilosus, Poa pratensis and so on. Naturalization rate (NR) was 6.9% of all 604 taxa of vascular plants and the invasive alien plants were 3 taxa including Solanum carolinense, Ambrosia artemisiifolia, Aster pilosus. This study is to identify the main plant distribution and protecting valuable plant populations Unjangsan areas in Jeollabuk-do is located in the inland performing will want to take as the basis for designating an ecological and landscape conservation areas.

The purpose of this study is to construct the basic data for establishing the forest ecosystem and environment by studying the flora distributed in Mt. Paljae, Chungcheongnam-do. The number of flora were summarized as 292 taxa including 88 families, 214 genera, 258 species, 2 subspecies, 27 varieties and 5 forms. The rare plant was Melothria japonica. The Korean endemic plants were 3 taxa including Salix koriyanagi, Philadelphus schrenkii and Paulownia coreana. The specific plants by floristic region were 16 taxa including Betula davurica, Salix chaenomeloides, Dictamnus dasycarpus, Hosta capitata and so forth. The naturalized plants were 34 taxa including Fallopica dumetorum, Rumex obtusifolius, Ailanthus altissima, Festuca arundinacea and so forth. Most of the plants commonly originated from North America. The 5 naturalized degree that was widely distributed and had many individual was the most common. Until 1921, after the opening of 1 period was the most common in the introduced period. The invasive alien plants were 4 taxa including Rumex acetosella, Solanum carolinense, Aster pilosus and Paspalum distichum var. indutum.

본 연구는 한우에 있어서 다배란처리에 의한 체내 정상수정란의 생산효율을 극대화하기 위하여 PEG에 용해한 FSH의 1회 피하주사 방법이 현재 사용하고 있는 1일 2회 4일간 근육 주사방법을 대체할 수 있는지를 결정하기 위하여 실시하였다. 연구결과 다회 근육주사 방법과 비교하여 1회 피하주사 방법이 황체수, 총 회수란수 및 이식가능 수정란수에 있어서 현저히 증가 (P〈0.05)하였다. 따라서 한우에 있어서 PEG에 용해시킨 Folltropin-V의 1회

본 시험은 Holstein종 수소를 조기에 외과적 거세 후 SR-rbST 투여시 사육 단계별 건물 및 영양분 섭취량 변화에 미치는 영향을 구명하기 위하여 Holstein 수소 32두를 공시 하여 얻어진 주요 결과를 요약하면 다음과 같다. 1. 건물 섭취량은 비거세구와 거세구는 큰 차이 가 없었지만 rbSTl구와 rbST2구는 각각 7.88kg과 7.65kg으로 비거세구와 거세구에 비해 6~9% 정도 건물 섭취량이 적었다. 2. NRC 비육우 요구량 대비

This research was carried out to investigate the effect of zeranol injection on dry matter(DM) and nutrient intake requirement by growth stage of early castrated bull with 3 treatments(bul1, steer, steer+zeranol) with 28 Holstein bull at National Livestoc

This experiment was carried out to investigate the effect of feeding order bay-concentrate-silage, concentratehay- silage, silage-concentrate-hay, silage-concentrate-hay, concentrate-silage-hay) on ruminal characteristics change with 3 fistulated dry Hols

Three fistulated nonlactating Holstein cows were used to examine the change in ruminal characteristics when fed diets of 100% corn silage, 50% corn silage + 50% wet brewers' grain(WBG) and 100% WBG, and also twenty Holstein heifers averaging 156 3.2kg BW

본 시험은 국내생산 주요 조사료인 볏짚, 옥수수사일레지, 목건초를 급여하면서 농후사료 수준을 조절하였을 때 반추생리 및 저작형태에 미치는 효과를 조사하기 위하여 농후사료 5개수준(0, 3, 6,9 12kg/일)에 젖소 15두를 공시하여 시험을 실시한 결과는 다음과 같다. 1. 건물섭취량은 볏짚, 옥수수사일레지, 목건초가 대사체중비 4.97, 5.47 그래고 5.60%를 섭취하였으며 농후사료 증가에 따른 조사료 건물섭취량 감소량은 볏짚 0.330, 옥수수

The purpose of this study is to estimate the thickness of concrete slabs using the impact echo method based on the stress waves, which is one of the nondestructive test method, to evaluate the safety and construction conditions of concrete slabs. If the correlation and reliability of the impact echo method and the slab thickness are secured, it can be considered that the quality control of the concrete slab is possible in existing structures and structures under construction.

Strain Hardening Cement-based Composites(SHCCs) are attractive materials for energy dissipation and crack damage mitigation. This study investigated the flexural performance of SHCC beams layered Strain-Hardening Cement-based Composite(SHCC). The flexural behavior of RC beams carried out four-point loading test. Test results indicated that PE30_20 compared with Con30 initial cracking load, the stiffness, the yielding strength was higher.
