Using traps and passive integrated transponder (PIT) telemetry, we investigated the effectiveness of nature-like fishway installed at Sangju Weir on Nakdong River, Korea. In 11 regular checks over study period, 1474 individuals classified into 19 species belonging to 5 families were collected by traps, representing 66% inhabiting main channel River. PIT tags applied 1615 22 species, revealing attraction passing rates 20.7% 14.5%, respectively. Interspecific differences also shown. For 63.2%...
Kellicottia bostoniensis is a rotifer species originating from North America, with numerous reports documenting its spread to Europe and South America. Meanwhile, in Asia, the occurrence of this non-native has been scarcely documented, but presence was recently reported Korea 2020. In Korea, close geographic proximity artificial reservoirs within small area expected make region vulnerable K. bostoniensis. Therefore, it deemed necessary study spatio-temporal distribution bostoniensis, which...
Stream development can generate environmental changes that impact fish communities. In temperate streams, the distribution of species is associated with gradients. To analyze relevant factors, large-scale exploration required. Thus, to evaluate patterns in Korea, sampling was conducted on a national scale at 720 sites over 6-week period 2009. A total 124 27 families were identified; Zacco platypus and koreanus Cyprinidae dominant subdominant species, respectively. Of found, 46 (37.1%)...
본 연구의 목적은 노인의 노화불안이 성공적 노화에 미치는 영향에서 사회적 지지의 매개효과를 검증하는 것이다. 연구결과, 첫째, 증가할수록 노화는 감소되는 것으로 나타났다. 둘째, 노화불안과 지지 관계에서 지지는 셋째, 지지와 노화 증가는 노화를 증가시키는 넷째, 노화의 부분매개효과를 확인하였다. 이에 연구는 고령화 사회에서 노화불안 감소와 위한 방안과 후속연구를 제언을 하였다. The purpose of this study is to verify the mediation effect social support in influence anxiety over aging elderly group on successful aging. results analyses are as follows: First, increased, decreased. Second, relationship between and support, decreased increased. Third, aging, an...
Exotic species in aquatic ecosystem generate various problems domestically as well globally. Largemouth bass (Micropterus salmoides) which is a well-known exotic globally, acts substantial disturbance factor on the native fish communities Korea due to high predation pressure and hence designated ecologically harmful by Ministry of Environ- ment. In this study, we investigated impact largemouth Korean population, crucian carp (Carassius auratus), identify responses prey fish. Two were col-...
[Purpose] The purpose of this research was to examine the effectiveness modified constraint-induced movement therapy (mCIMT) on upper extremity function and occupational performance stroke patients. [Participants Methods] An experimental study carried out two groups 7 participants selected by a specific criterion. group received mCIMT as well conventional rehabilitation (CRT) for 5 days per week over 2 period. control only CRT. Outcome measures included Manual Function Test (MFT), Motor...
In this study, we examined the ontogenetic changes in prey selection pattern of largemouth bass Micropterus salmoides (Lacepede, 1802) accordance with habitat type. The stomach contents were analysed respect to predator size classes for two different habitats (Nakdong River main channel and Upo Wetlands tributary) South Korea, that differed diversity potential items. (H′) invertebrate diet items was found significantly between study sites. Small large mouth (<100 mm) preferred consume...
To monitor changes of fish assemblage, we selected 5 study sites in lower-middle part the Mankyeong (3 sites) and Dongjin (2 River, conducted field sampling 2 to 4 times per year from 2007 2009. Total sampled fishes were 66 species 16 families. Cyprinidae (RA, 73.25%; 33 species) was dominant family. Dominant Zacco platypus 19.96%), subdominant Chelon haematocheilus 11.11%). There 18 Korean endemic 12.56%) one endangered species, Liobagrus obesus, only found River. Three exotic found:...
상대 무게 지수 (Relative weight index, Wr)는 어류의 표준무게와 실측 무게의 비율을 산출하는 지수로써 영양상태를 평가하는데 활용된다. 본 연구의 목적은 활용을 위해 국내 담수어류 10종의 표준 산출을 위한 길이-무게 상관관계 (표준 LWRs)를 것과, 산출결과에 대한 빈도 분포를 분석하는 것이다. 총 141개 조사 지점에서 798회 어류 채집을 통해 확보한 데이터를 활용하여 LWRs를 산출하였다. LWRs는 매개변수 a와 b값을 95% 신뢰한계 (confidence limits)와 함께 제시하였으며, 모든 종에서 결정계수 (r2)는 0.9 이상으로 산출되었고, b값은 Froese (2006)의 예상 범위에 포함되었다. 산출 결과에 분포 분석은 각 종별로 10~90 백분위수를 10 단위로 산출하여 이는 지수를 정량적으로 평가하기 기준으로 활용될 수 있을 것으로 판단된다.
