  • This study was conducted to evaluate the allelopathic effect of aqueous extract of Ganghwa domestic mugwort (Artemisia spp.) on vegetables and its related allelo-chemicals. When the receptor vegetables, such as Chinese cabbage, lettuce, and red radish, were treated with aqueous extract obtained from Sajabalssuk (A. $sp^*I$), Ssajuarissuk (A. $sp^*II$) or Ssajarissuk (A. $sp^*III$), their germination rate, leaf number, plant height, and root length were restricted with increasing concentration of aqueous extract. Allelopathic effect was the highest in radish, than lettuce and Chinese cabbage in order. The growth of topplant were more inhibited then root growth observing in restriction of plant height, root length, and chlorophyll contents. The plant height, the root length of red radish were 53.3 and 61.2% and their fresh weights were 19.8 and 26.4% compared to those of controls, respectively. A. $sp^*III$ showed the highest allelopathic effect among the donor plants. In HPLC analysis, 7 phenol compounds were identified in A. $sp^*I$ and A. $sp^*II$, and, in A. $sp^*III$, and hydroxybenzoic acid and phenylacetic acid were further identified as allelochemicals. It is considered that their plant growths were variously inhibited by the amounts and types of allelochemicals in aqueous extracts. To increase the productivity of farm land after cultivation of mugwort, these results can be useful to select the following field crops.

  • 본 연구는 최근 다양한 기능이 보고된 쑥의 eupatilin성분과 jaceosidin 성분 고함유 유전자원을 선발하고 기능성 작물로서의 개발가능성을 제시하고자 실험을 실시하고 그 결과를 요약하면 다음과 같다. 1. 12개 지역의 도서벽지에서 수집한 자생쑥을 분석한 결과 강화${\cdot}$백령도 지역의 수집 쑥에서 eupatilin과 jaceosidin함량이 높았다. 그 중 가장 높은 것은 강화의 싸주아리 쑥이었다. 2. 쑥의 채취시기별 함량을 분석한 결과 eupatilin과 jaceosidin 함량은 모두 5월 23일에서 6월 10일 사이 채취한 쑥에서 가장 높았다. 3 쑥의 식물체 부위별 함량을 분석한 결과, eupatilin 함량은 상위엽이 하위엽보다 2배가량 많이 함유되어 있었으나 jaceosidin 함량은 그 차이가 크지 않았다.

  • The purpose of this study is to report the treatment effects of Korean medicine for patients with lateral epicondylitis. This study was done on 12 cases of patients with lateral epicondylitis who visited in Korean Medicine Clinic of Ganghwa-gun Public Health Care Center. We used muscle contraction/relaxation strengthen technique, Instrument assisted soft tissue mobilization (IASTM), acupuncture on patients and mesured numerical rating scale (NRS), pain disability index (PDI), and grip strength test to evaluate treatment effects. Among twelve patients, eleven cases showed decreasing in NRS and all cases showed decreasing in PDI. Ten cases showed increasing in grip strength test. Korean medical treatments including muscle contraction/relaxation strengthen technique and IASTM are thought to be one of the effective treatment for patients with lateral epicondylitis.

  • We find out the clusters with high toxoplasmosis risk to discuss the geographical pattern in Gyodong-myeon and Samsan-myeon of Ganghwa-gun, Cheorwon-gun, and Goseong-gun, Korea. Seroepidemiological data of toxoplasmosis surveyed using rapid diagnostic tests for the residents in the areas in 2019 were analyzed to detect clusters of the infection. The cluster was investigated using the SaTScan program which is based on Kulldorff's scan statistic. The clusters were found with P-values in each region analyzed in the program, and the risk and patient incidence of specific areas can be examined by the values such as relative risk and log likelihood ratio. Jiseok-ri and Insa-ri were found to be a cluster in Gyodong-myeon and Seokmo-ri was the cluster in Samsan-myeon. Yangji-ri and Igil-ri were found to be a cluster in Cheorwon-gun and Madal-ri and Baebong-ri were the cluster in Goseong-gun. This findings can be used to monitor and prevent toxoplasmosis infections occurring in vulnerable areas.

  • This study aimed to characterize the seasonal abundance of hard ticks that transmit severe fever with thrombocytopenia syndrome virus from April to November 2019 and 2020 on Ganghwa-do, Incheon Metropolitan City, Korea. The ticks were collected at grassland, grave site, copse and mountain road using a collection trap method. The ixodid hard ticks comprising three species (Haemaphysalis longicornis, H. flava, and Ixodes nipponensis) collected were 6,622 in 2019 and 3,811 in 2020. H. longicornis was the most frequent (97.9% in 2019 and 96.0% in 2020), followed by H. flava (2.0% and 3.0% in 2019 and 2020, respectively) and I. nipponensis (less than 0.1%). Our study demonstrated that seasonal patterns of the tick populations examined for two years were totally unsimilar. The hard ticks tested using RT-qPCR were all negative for severe fever with thrombocytopenia syndrome virus.

  • The purpose of this study is to review the research on Gangbang Palace and to presume the location of the palace through the study of feng shui. when the Mongols invaded, Ganghwado was the capital, moved from Gaegyeong and it was maintained for 39 years. At that time, the palace construction followed the palace of Gaegyeong, and the names such as Gujeong毬庭, Palace, and Sasa寺社 were the same as those of Gaegyeong. However, despite several archaeological excavations at Goryeo Palace Site, Historic Site No. 133, no actual remains of the Goryeo period were found. After the negative opinions on the current Goryeo Palace site became public, there have been several previous studies on the estimation of the location of the Goryeo Palace Site, and although there have been achievements, the location of the Goryeo Palace is still not confirmed. The key to presuming the location of the GangdoPalace江都宮闕 is first, whether the palace was located in the south of Songaksan, and second, at what point it was located in the south of Songaksan. As to whether the palace was located in the south of Songaksan, it was presumed that the Chiso治所 of Ganghwabu was located in Gukhwari, referring to the record in 『Shinjeungdongguknyeojiseungnam新增東國輿地勝覽』 that Goryeosan, a guardian mountain鎭山, was 'five ri west of Bu府西五里'. Accordingly, the location of the palace of 'Budongsimni 府東十里' in the old literature was estimated to be south of Songaksan Mountain. Also, the location of the palace on the south side of Songaksan was approached from a feng shui theory. Three places for the palace to be located are presumed to be 'Ganghwa Girls' High School', 'Seonggwang Church', or 'Above the Ganghwa-gun library', and the central axis of the palace is estimated to be 'Above the Ganghwa-gun library' where the corridor-type building relics were found among them, and the other two areas were presumed to be other buildings within the palace.

  • Toxoplasma gondii seroprevalence have been rapidly increasing in some parts of Korea. We analyzed prevalence of anti-Toxoplasma gondii antibodies, using a rapid diagnostic test (RDT), in the sera of 552 residents in Ganghwagun, 661 ones in Cheorwon-gun, and 305 ones in Goseong-gun, Korea in 2019. IgG/IgM RDT mounted with recombinant fragment of major surface antigen (SAG1), glutathione-S-transferase-linker-SAG1A, were applied to the sera. IgG seroprevalence was 28.1% in Ganghwa-gun, 19.5% in Cheorwon-gun and 35.7% in Goseong-gun. Odds ratios comparing Cheorwon vs Ganghwa was 0.63 (P=0.001) and Goesong versus Ganghwa was 1.47 (P=0.01) adjusting age and sex. Goseong had highest seroprevalence among the 3 counties both in crude rates and logistic regression. Although Cheorwon and Goseong are adjacent to the demilitarized zone (DMZ) in Korea, seroprevalence rate was much higher in Goseong. Further investigation on other DMZ-closed areas is necessary whether they have high prevalence rates compared to the other areas. T. gondii prevalence in Korea is still persists; proper health policy should be established.
