BACKGROUND: As consumption of unripe mandarin increases, its cultivation has increased in open field cultivation areas. Because unripe mandarin must be harvested before ripening and color change, the optimum harvest time must be determined. This study investigated the effect of the harvest season on the yield of unripe fruit and biennial flowering of ‘Miyagawa’ satsuma mandarin. METHODS AND RESULTS: Two areas of unripe mandarin orchard were selected, and the yield, fruit growth, working time, and flowering of trees the following year were investigated. Fruit was harvested at 40, 60, 80, 100, and 120 days after full bloom and at general ripening. Fruit yield of unripe mandarin increased with later harvest time from 100th to 120th day except normal ripening. The next year, biennial occurred with normal ripening and harvesting, but not at the 120th day after full bloom. At the 40th day (earliest harvest time), summer and autumn shoots were present, but not after the 100th day. The 40th day required the most harvesting time; because the time gradually decreased with later harvest, the harvest time was shortest on the 120th day, and general ripening occurred shortly after the 120th day. CONCLUSION: Harvesting of unripe mandarin 100–120 days after full bloom was ideal to reduce harvesting time, enhance yield, and enable flowering the following year.

Effect of Scion Root Occurrence on the Flowering, Fruit Quality and Yield of ‘Shiranuhi’ Mandarin Hybrid in Plastic Film House

As most of citrus, shiranuhi mandarin ((Citrus unshiu × C. sinensis) × C. reticulata) mainly use the trifoliateorange (Poncirus trifoliata) as its rootstock which has dwarf and cold hardness in Korea. However, recently,scion root was observed in ‘Shiranuhi’ mandarin tree grafted onto the trifoliate orange. This study was carriedout to find out effects of scion root occurrence on the fruit quality, flowering and yield of shiranuhi mandarin. For the experiment, we selected six farmers who have outbreak of scion root in their Shiranuhi mandarinorchards and surveyed the difference of fruit quality of shiranuhi mandarin hybrid between scion root andcontrol (trifoliate orange root). In the results, flowering was severely decreased in scion root trees compared tocontrol. As a result of survey of 174 Shiranuhi mandarins, 160 trees were proved to be scion root, and had lessflowering. Fruiting of scion root also severely dropped compared to control and thus, yields of scion root (6.4kg) reduced by 24% compared to control (26.7 kg). The fruit size, weight and soluble solid contents of scionroot were significantly reduced, but there were no differences in acid contents and coloring of fruit. From theresults, we concluded that scion root had negative influence on flowering, fruit size and the yields ofShrinanuhi mandarin hybrid.

Effect of Exposed Length of Rootstocks on the Occurrence of Bitter Pit and Tree Vigor of ‘Gamhong’/M.26 Apple Cultivar

‘Gamhong’ apple cultivar which was bred by National Institute of Horticultural and Herbal Science, has high sugar contents, large types of fruit and mid-season types of cultivar. However, ‘Gamhong’ apple tree is very sensitive cultivar to bitter pit. Therefore, many farms have not solved the problems on bitter pit to cultivate ‘Gamhong’ apple tree. This study was carried out to find out the exposed length of rootstocks on the occurrence of bitter pit and fruit quality of ‘Gamhong’/M.26 apple tree and seek the ideal cultivation strategy to decrease bitter pit to cultivate it. For this research, ten-years-old ‘Gamhong’/M.26 apple trees were used. The differenceamong the treatments of the exposure of rootstock of RL (5 cm), RM (15 cm) and RH (20 cm) from the soil surface was observed with 4 repetition from 2010 to 2011. Decreased exposure of rootstocks resulted in more vigorous growth, taller height, and greater number of shoots. N and K/Ca of RH was tend to be lower than RM and RL, whereas as the exposure of rootstock decreased, fruit weight and bitter pit increased. Therefore, occurrence of bitter pit in RH was significantly lower than that of RM and RL treatment and fruit weight also decreased. There was no difference on nutrient contents of leaf and the fruit quality by the exposed of rootstock in ‘Gamhong’ M.26 apple tree. To reduce the occurrence of bitter pit, it may be helpful to keep the optimum exposure of rootstock within 20 cm from the soil surface.

한반도 남서해안 상부조간대의 퇴적상 및 지구화학적 특성

우리 나라 남서해안의 상부조간대에 분포하는 퇴적물의 퇴적상과 지구화학적 특성을 살펴보기 위하여, 이들 시료를 대상으로 퇴적물의 입도별 분포와 금속원소의 함량에 대한 분석을 실시하였다. 퇴적물의 입도는 잔자갈에서 니질크기로 불규칙한 분포특성을 가진다. 퇴적물의 분급도는 매우 양호한 분급에서 매우 불량한 분급으로 다양하게 나타났으며, 왜도는 대체로 양의 왜도가 우세하였다. 퇴적물 내에 함유된 금속원소들의 지구화학적 거동은 퇴적물 입도에 대한 의존도가 일부 영향을 주기는 하였으나, 복잡한 해저지형과 심한 변화를 보이는 조류 및 주변지질의 환경적 변화에 의해 많은 영향을 받은 것으로 보인다. 퇴적물에 함유된 금속원소들의 농축을 알아보기 위한 농집지수는 Co와 Cr이 보통 내지 심한 오염으로, Cu와 Ni가 보통 오염에 해당하였으나 특별한 집중 경향이 인지되지는 않았다. 따라서, 남서해안 퇴적물의 입도와 금속원소들의 함량분포는 복잡한 해저지형과 이에 따른 조류 유형의 심한 변화 그리고 주변지질 등이 복합적으로 영향을 미치는 해역으로 해석된다. In order to reveal sedimentary facies and geochemical characteristics on sediments distributed in upper intertidal zone, the southwestern coast of Korea, grain size and metal content analyses to the sediments were carried out. The grain size distribution of sediments shows very wide range from gravel to mud. The sediments are very well sorted to very poorly sorted and mostly positively skewed. Geochemical behavior of metals in the sediments is dependant on grain size, in part, but might be much controlled by complex submarine topography, highly varied tidal currents and surrounding land geology in the study area. Igeo (index of geoaccumulation) representing metal condensation in the sediments moderately/strongly polluted in Co and Cr and moderately polluted in Cu and Ni. But notable metal condensations are not found in the study area. So, it might be interpreted that grain size and metal content distribution tendencies in the sediments are considerably influenced by complex submarine topography, highly varied tidal currents and surrounding land geology.

Objectives : This study aimed to evaluate the efficacy of manual therapy for knee meniscus injuries. Methods : We searched seven electronic databases (MEDLINE, Cochrane Library, CAJ, Wanfang, RISS, ScienceON, and OASIS) to collect randomized controlled trials(RCTs) using the keywords “manual therapy OR chuna OR tuina” and “meniscus injury.” Results : Eleven RCTs were selected based on the inclusion criteria, and all studies were conducted in China. Five studies were meta-analyzed. The systematic review revealed a positive effect of manual therapy for knee meniscus injury. Low risk of selection, attrition, and reporting bias were demonstrated in all studies. Ten studies had a high risk of performance bias. Conclusions : The systematic review reported favorable results using manual therapy for knee meniscus injury. However, this study has several limitations because of the high risk of bias. Further clinical studies and reviews with higher levels of evidence are warranted.

강석범,신상은,윤석태,고영구,오강호 全南大學校 師範大學 科學敎育硏究所 2005 科學敎育硏究誌 Vol.29 No.1

To consider depositional environments in the upper intertidal zones of Haenam to Jindo areas, southwestem coast of Korea, sediments from the above areas were studied in size analysis. In size, the sediments are very coarse sand to fine silt. The sediments are moderately to very poorly sorted. And, the sediments are coarse to very fine skewed and platy- to lepto- kurtic. In facies, the sediments are composed of msG, gravelly gmS, gS, (g)mS, (g)S, S, zS, sZ and Z. The depositional environments in the study area are widely variable, being connected by tidal and wave based influences.

To consider the depositional characteristics of supratidal zones near the Wando area of Chonnam province, the sediments of the area were analyzed in size distribution and sedimentary facies. The sediments are 2.89 - 6.06∅(avg. 4.93∅) and 1.53 - 2.63 (avg. 2.29∅) in mean size and sorting. And, the sediments are fine to very fine skewed in the range of 0.17 - 0.68(avg. 0.30). Synthesizing the study results, it is considered that the study area is a finely depositional environment with the low levels of tides and waves, differentiated from strong tide-dominated ones related with complicated submarine topographies like as Mokpo or Jindo-Haenam areas.
