가시고기(Pungitius sinensis sinensis)와 잔가시고기(P. sinensis kaibarae)의 공서지역인 강릉시 지변저수지 하류의 소하천에서 이들 어류를 채집하여 조사한 결과 두 유형의 중간형으로 생각되는 개체가 발견되었다. 전기영동 결과 P. sinensis sineis와 P. sinensis kaibarae는 종전에 보고된 바와 같이 뚜렷이 구분되는 전기영동상을 나타내고 있었으나, 그 외에 이들 사이의 잡종으로 여겨지는 개체가 약 10%정도 발견되었고 또 이들은 가시고기형 잡종과 잔가시고기형 잡종으로 구분되 었다. 형태적인 면에서도 문장(吻長)과 미병고(尾炳高)는 잡종의 특정을 잘 나타내고 있었으며 정소의 색깔에도 P. sinensis sinensis는 회색, P. sinensis kaibarae는 검은색이었지만 잡종개체는 그중간의 색을 띄고 있었다. 이러한 잡종개체의 출현에 따른 이들 두 분류군의 생식적 격리문제에 대하여 논의하였다.

Purpose: This study was done to determine the extent of Clonorchis sinensis infections as well as other parasitic infections and to determine the growth rate. Method: Analyzed test results were from 1,050 bowel samples taken at 3 public health subcenters located in Muju, North Jeolla Province during February and March 2007. Result: The results are summarized as follows; The egg positive rate by stool examination was 4.3%. Ascaris lumbricoides, Enterobius vermicularis, Clonorchis sinensis, Trichuris trichiura, Metagonimus, Paragonimus were detected. No one was infected with multiple parasites. Infection rate for Clonorchis sinensis was 3.5%. Statistical correlation to Clonorchis sinensis infection rate was as follows; Gender (p=0.001), Age (p=0.005), Proximity to a river (p<0.000), Drinking (p<0.000), Smoking (p=0.009), Cooking of freshwater fish (p<0.000), Confidence in subjective health status (p=0.032), Family history of infection (p=0.005), No significant correlation was found between Clonorchis sinensis infection rate and duration of stay (p=0.809) in the agricultural communities or between Clonorchis sinensis infection and knowledge of Clonorchis sinensis (p=0.113). Conclusion: The results of this survey show that there is a need to develop a program to test the condition of Clonorchis Sinensis infection and its growth rate in residents of rural communities.

The object of this study is to differentiate the reproductive behaviors of Pungitius sinensis and P. kaibarae inhabiting the southern part of the Korean Peninsula. We collected P. sinensis from Jusu stream, Okkyemyeon and P. kaibarae from Sacheon stream, Sacheon-myeon both in Gangwon province and subsequently raised and observed them in an aquarium. At the beginning of the reproductive season, male P. sinensis got tinged with dark green, made a territory, and built nests on the bottom. On the other hand, male P. kaibarae became black all over, its white ventral spines became conspicuous and built nests on the stems of waterweed off the bottom. In the courtship dance, male P. sinensis made frequent attempts to entice females into their nests after many bitings, while male P. kaibarae mostly did this with conspicuous jumpings. In courtship behaviors, the body's angle of male P. kaibarae with his head down was larger than that of male P. sinensis by 50-60 degrees. During courtship, the biting frequency as an index of aggressive behavior was greater in P. sinensis and the jumping frequency as an index of sexual behavior was greater in P. kaibarae. During the courtship dance, bitings tended to suppress jumpings, for P. sinensis, but not for P. kaibarae.

Cedrela sinensis is a Korean traditional wild herb found especially in the southern provinces of Korea. This study investigated the effects of Cedrela sinensis powder on the antioxidant activities and quality characteristics of bread. Bread was prepared with different amounts of Cedrela sinensis powder (at ratios of 0, 1, 2, and 3% of total flour quantity). The results showed that the dough pH, moisture, and fermentation tension levels decreased as Cedrela sinensis powder content increased. Bread volume and specific volume decreased (p<0.01) with an increasing amount of Cedrela sinensis powder (Bread weight increased (p<0.001)). As Cedrela sinensis powder content increased, color 'a' value decreased, and 'b' value increased. Sensory parameters such as color (p<0.01), flavor (p<0.01), appearance (p<0.001), taste, softness (p<0.05), and overall quality (p<0.01) of bread containing 2% Cedrela sinensis powder were measured. Total phenol contents and DPPH free radical scavenging activity of bread significantly increased with increasing Cedrela sinensis powder content (p<0.001). Based on these results, we suggest that Cedrela sinensis can be used for increasing the consumer acceptability and functionality of bread.

참죽나물은 맛과 향 및 붉은 색이 조화를 이루는 귀한 산채 중의 하나로 우리나라와 중국에서만 이른 봄에 참죽나무 순을 데쳐서 나물로 먹었던 전통식품 중의 하나이다(Kim et al. 2012). 본 연구는 전통 산채인 참죽나무 잎을 분말화한 후 첨가량을 달리하여 전병반죽에 첨가하여 total phenolic content, DPPH free radical 소거활성을 측정하였으며 참죽 전병의 품질특성을 비교분석하기 위해 반죽의 수분 및 pH, 전병의 비중, 수분, 색도, 경도, 관능평가를 실시하였다. 이를 통해 참죽나무 잎의 저장성과 가공방법을 연구하고 전병에 첨가하여 기호 및 영양학적 가치를 높이고자 하였다. 참죽 전병의 total phenolic content는 참죽 분말 12%를 첨가한 첨가군이 $161.1{\pm}0.09$ mg GAE/100 g로 가장 높았다. DPPH free radical 소거활성은 $1000{\mu}g/m{\ell}$ 수준에서 12% 첨가군이 가장 높은 활성을 보였다. 반면 반죽의 pH와 수분함량은 참죽 분말이 증가함에 따라 감소하였으며, 전병의 수분함량 또한 감소하였다. 전병의 색도는 L값과 b값은 참죽 분말 첨가량이 증가할수록 낮아지고, a값은 높아지는 유의적인 차이를 나타냈으며, 경도는 시료 첨가에 따라 다소 증가하는 경향을 나타내었다. 관능검사에서는 9% 첨가군이 모든 항목에서 가장 높은 선호도를 보였다. 이러한 결과들로 미루어 보아 참죽 분말은 뛰어난 항산화능을 보이고 있으며 가공식품의 기능성 재료로 충분한 가치가 있음을 확인할 수 있었다.

In this investigation, the accumulation mineralization and annual cycle of organic P has been studied in grassland ecosysterns of a Z japonica grassland and a M sinensis grassland on Mt. Kwanak. The basic models of the accumulation and mineralization for ash components of a grass-litter have been presented as the equations (1), (2), and (3). The equations (7)~(10) for organic P are derived from these basic concepts. There was a highty significant relationship between organic matter and organic P. The estimates between organic matter and organic P correlated very high significance. The parameter factors k or k' of mineralization of organic P for the Z. japonica and M sinensis asslands were k=0.412 or k'=0.292 and k=0.224 or k'=0.183, respectively. The time required for a cycle to be completed from organic P to inorganic P of 50, 95 and 99 % are 3.9, 16.7 and 27.8 years in the Z. japonica grassland and 4.1, 17.7 and 29.4 years in the M sinensis grassland. The annual P cycle formulae for mineralization were based on the equations (5), (11) and (12). Annual yields of mineralization for organic P in the steady state grasslands of Z. japonica and M sinensis were 0.407 and 0.504g /$m^2$, respectively.

휴전선(休戰線) 이남의 한반도(韓半島)에서 채집된 가시고기 P. sinensis의 12 개체군에 대하여 인판(鱗板)의 수 및 형태의 지리적 변이를 조사하였다. 인판(鱗板)의 수에 지리적(地理的) 경사(傾斜)는 보이지 않았지만 P. sinensis sinensis가 P. sinensis kaibarae 보다 다소 더 많이 나타나고 있어 두 아종(亞種) 간에 변이폭이 달랐으나 형산강 개체군은 매우 심한 변이를 나타내고 있었다. 인판(鱗板)의 크기는 금호강의 개체군이 가장 컸다. 형산강 개체군의 것은 크기도 작고 매우 퇴화적인 경향을 나타낼 뿐 아니라 semiarmatus형(型)의 인판배열(鱗板排列)을 지닌 개체도 발견되고 있어 P. sinensis의 특수형으로 취급하였다. 육봉화(陸封化)와 인판(鱗板)의 크기 사이의 관계에서 보아, 형산강의 개체군이 가장 먼저 육봉화(陸封化)되었으며, 금호강의 개체군을 제외한 다른 P. sinensis kaibarae 개체군들은 보다 늦은 시기에 육봉화(陸封化)되었을 것으로 생각된다. 그러나, 육봉화(陸封化)되어 있으면서 내륙 깊이 존재하고 있는 금호강의 개체군이 가장 잘 발달된 인판(鱗板)을 지니고 있으며 인판(鱗板)의 수도 적지 않다는 사실에서, 이 개체군에는 염분내성(鹽分耐性) 및 육봉화(陸封化)와 인판(鱗板)의 수 및 발달이 서로 관계가 없음을 의미한다. 이러한 여러 사실로 보아 형산강과 금호강에 서식하고 있는 P. sinensis kaibarae 사이의 관계에 대해서는 보다 세밀한 조사가 요망된다.

Korean freshwater turtles are divided into native turtles, Chinemys reevesii in Geoemydidae, Pelodiscus sinensis in Trionychidae, and imported turtles, Trachemys scripta elegans, T. s. scripta, Pseudemys rubriventris and Ocadia sinensis. In this study, we determined the distribution of Korean freshwater turtles based on a field study and literature study, and considered the taxonomic position of unidentified native turtles. The study was carried out between May 2010 and November 2011 during the day time, and the capturing tool used to collect turtles consisted of net and metal frame. C. reevesii and P. sinensis were found in 16 and 11 places, respectively. C. reevesii, which inhabits the Korean peninsula, is a taxonomically controversial species, but it is presumed that the turtle belongs to Mauremys. Moreover recent taxonomic studies of the soft-shell turtle have shown that the Korean native species is P. maackii, and P. sinensis was imported from abroad and has been in the natural habitats of Korea since 1970s. The exterior shape and skeletal form of P. maackii and P. sinensis are nearly similar. However, the skin color and yellow spots on the shell could be used to distinguish the two species.

Lots of progress have been made about pathogen system of Hibiscus rosa-sinensis and hibiscus chlorotic ringspot virus (HCRSV), however, interactions between H. rosa-sinensis and HCRSV remain largely unknown. Hereon, firstly, HCRSV infection in H. rosa-sinensis from Zhangzhou city of China was confirmed by traditional electron microscopy, modern reverse transcription polymerase chain reaction and RNA-seq methods. Secondly, sequence feature analysis showed the full-length sequence of HCRSV-ZZ was 3,909 nucleotides (nt) in length and had a similar genomic structure with other carmovirus. It contains a 5' untranslated region (UTR), followed by seven open reading frames encoding for P28, P23, P81, P8, P9, P38, and P25, and the last a 3-terminal UTR. Thirdly, HCRSV-ZZ-derived vsiRNAs were identified and characterized for the first time from disease H. rosa-sinensis through sRNA-seq to reveal interactions between pathogen ant plant host. It was shown that the majority of HCRSV-ZZ-derived vsiRNAs were 21 nt, 22 nt, and 20 nt, with 21 nt being most abundant. The 5'-terminal nucleotide of HCRSV-ZZ vsiRNAs preferred U and C. HCRSV-ZZ vsiRNAs derived predominantly (72%) from the viral genome positive-strand RNA. The distribution of HCRSV-ZZ vsiRNAs along the viral genome is generally even, with some hot spots and cold spots forming in local regions. These hot spots and cold spots could be corresponded to the regions of stem loop secondary structures forming in HCRSV-ZZ genome by nucleotide paring. Taken together, our findings certify HCRSV infection in H. rosa-sinensis and provide an insight into interaction between HCRSV and H. rosa-sinensis and contribute to the prevention and treatment of this virus.
