  • We conducted eight surveys in the northern East China Sea (ECS) in winter (February - April), summer (July), and autumn (October) 2004-2009, to investigate the seasonal distribution of T. pacificus. A total of 482 paralarvae, ranging in mantle length (ML) from 1.0 - 17.0 mm, were collected at 73 out of 181 stations. There were higher numbers of paralarvae during the winter and summer months than in the autumn. There was significant seasonal variation in the paralarval mantle lengths; mantle lengths were longer in winter (April) than in summer (July). The position of oceanic fronts in the study area played an important role in restricting paralarval distribution along the inshore edge of the Tsushima Warm Current (TWC). When the TWC expanded to western Jeju Island in winter and autumn, the paralarval distribution range extended to include western Jeju Island. However, when the TWC was located southeast of Jeju Island in the summer, paralarvae were distributed along the frontal zone off southeast Jeju Island. Sites at which paralarval mantle length was <2.0 mm ML indicated that the spawning ground were likely to be within the northern ECS in winter and summer, but north of the study area in autumn.

  • 파슬리의 재배시기별 MA 저장성을 비교하였는데, 먼저 수확 당시 파슬리의 품질을 보면 엽록소 함량은 여름재배, 비타민 C 함량은 가을재배에서 그리고 경도는 겨울재배에서 가장 높게 나타났다. 각각 가을, 겨울 여름에 재배한 파슬리를 0.04mm세라믹 필름으로 포장하여 0$0^{\circ}C$에서 저장한 결과 겨울재배 처리구가 84일간 저장이 가능하였고 다음으로 가을재배가 77일, 여름재배는 56일로 가장 짝은 저장기간을 보였다. 생체중 감소는 여름재배 처리구에서 가장 컸다. 포장내 이산화탄소와 에틸렌 농도는 가을과 겨울에 재배한 처리구는 낮았고 서로 유사한 경향을 보였으나 여름재배 처리구는 수확 당시 높은 포장열과 이로 인한 저장 중 높은 호흡으로 이보다 $2{\sim}3$배 높았다. 이러한 결과는 여름재배 처리구가 가을과 겨울에 재배한 처리구에 비해 경도, 엽록소, 비타민 C함량 등의 품질이 단기간 내에 현저히 감소를 초래하였다. 이상의 결과로 보면 수확시기별로 겨울에 수확한 파슬리의 저장성이 가장 우수하였고 파슬리 MA저장시 장기저장을 위해서는 수확직후 포장열 제거가 매우 중요하다는 것을 알 수 있었다.

  • A total of 168 seven days-old Arbor Acres chicks were reared in late-autumn on 4 types of litters; sawdust, rice husk, sugarcane bagasse or wheat straw up to 49 days of age to compare the growth performance, evaluate the manureal value and Coccidial oocyst population in used litter. Sadust, rice husk, sugarcane bagasse and wheat straw did not differ statistically for live weight, feed consumption, feed conversion ratio and survivability (p>0.05). However, live weight and survivability tended to increase on sawdust. The highest moisture content of used litter was found in sugarcane bagasse followed by sawdust, rice husk and wheat straw (p<0.05). Rice husk contained the highest amount of of nitrogen, phosphurus and potassium followed by sawdust, sugarcane bagasse and wheat straw (p<0.01). Oocyst content of all treatment groups increased suddenly up to 5 weeks of age and thereafter suddenly declined up to 7 weeks of age. Litter materials did not differ at 35 and 42 days of age for oocyst content, but significantly differed at 49 days of age (p<0.01). So, the above findings reveal that sawdust may be suitable litter followed by rice husk, sugarcane bagasse and wheat straw in late-autumn in Bangladesh in respect of broiler growth performance.

  • Objective : Jeol-sik, (festive seasons every 15 days based on sun cycle), refers to both Korean Traditional Festival food(jeol-sik), intertwined between months, and in-season meals(si-jeol-sik) in which the ingredients used are produced in each and one of the four season. I found that ingredients in Si-jeol-sik of Autumn are helpful for strengthening one's life force. Method : The study found that si-jeol sik for fall season has strong characteristic of casting out demons. When making songpyeon(half-moon-shaped rice cake) for Chuseok (Korean Thanksgiviing Day), they are steamed with pine needs spreaded underneath because pine needles are believed to have power in casting away evil spirits. For harvest ceremony, which were frequently held in October, people consumed steamed rice cakes garnished with red beans, which were considered to negate bad fortunes. Result : To prevent respiratory diseases caught esaily in fall due to wide daily temperature difference and dry weather, white good ingredients such as radish, pear, and taro are used. Conclusion : Main fall holidays are Chil-soek, Baek-Jung, Chu-seok. The best feature of Si-jeol-sik for fall season is that they cast out demons. Also, fall si-jeol-sik consist of many white ingredients for protecting lungs.

  • A study on the seasonal changes in the phytoplankton community was carried out in four aquaculture ponds of Bangladesh over a period of 16 months from August 2000 to November 2001. Out of 45 phytoplankton species identified, 30 belong to Cyanophyceae, 7 to Chlorophyceae, 5 to Bacillariophyceae and 3 to Euglenophyceae. The highest phytoplankton abundance was observed in spring followed by early autumn, summer, and the lowest was in winter. The annual succession of Cyanophyceae was characterized by spring and early autumn period dominated by Microcystis sp. Anabaena sp. and Planktolymbya sp. with Microcystis sp. as the main blue-green algae represented. Chlorophyceae was characterized by rainy season domination of Chlorella vulgaris, Pediastrum sp. and Scenedesmus denticulatus with maximum abundance of Chlorella vulgaris. Whereas Bacillariophyceae was dominant during the winter period. Navicula angusta and Cyclotella meneghiniana were the most frequently occurring species of Bacillariophyceae throughout the study period. Euglenophyceae was dominant in late autumn and Euglena sp. was the dominant species. The effect of various physicochemical water quality parameters on the seasonal distribution and succession of the above mentioned phytoplankton population as well as the interaction and eutrophication are discussed.

  • The catch performance of the silver-white jig for automatic jigging machine, developed to improve the effectiveness of LED fishing lamp in catching squid, was compared to that of the conventional green jig. The vessels used in this investigation were Haesong-ho (A-vessel), a training vessel of Gangwon State University and Haengbok-ho (B-vessel), a commercial fishing boat. In the case of the A-vessel, five to eight automatic jigging machines were used in the fishing operation with a 31.3 kW LED fishing lamp in summer. As for the B-vessel, fourteen automatic jigging machines were used with a 43.2 kW LED fishing lamp in autumn and winter. The results showed that the catch performance of the silver-white jig was similar to that of the green jig in the case of the A-vessel (p>0.05). However, in the case of the B-vessel, the catch performance of the silver-white jig was superior to that of the green jig in both winter (p<0.05) and autumn (P<0.001). Based on the catch performance results regarding the B-vessel in autumn, it is expected that the annual income increase that can be earned by using the silver-white jig will be KRW 26,385,000.

  • 수레국화는 초롱꽃목 국화과의 한해살이풀 또는 두해살이풀로 가을과 봄에 파종이 가능한 작물이다. 수레국화 꽃은 파란색, 분홍색, 연분홍색 등 다양하며 주로 봄부터 가을까지 개화가 가능하다. 이 작물은 종종 지역 축제 현장에서 아름다운 경관을 조성하고 있는데 수레국화 단독으로 재배되거나 양귀비와 혼합하여 재배되기도 한다. 따라서 경관조성이 가능한 작물인 수레국화의 녹비 수량과 개화특성을 조사하여 농경지의 이용 가능성을 검토하고자 사토, 사양토, 양토, 식양토 4개의 토성에 가을과 봄에 파종하여 시험을 수행하였다. 수레국화의 4개의 토성의 평균 월동율은 58.7%였으며 사토에서 가장 좋았다. 수레국화가 개화된 이후의 질소함량은 $15.0g\;kg^{-1}$이었고, T-C는 $409.2g\;kg^{-1}$이었으며, C/N율은 28.6이었다. 수레국화 파종시기에 따른 녹비의 건물수량은 가을파종보다는 봄파종에서 더 많았으며 토성별로는 봄파종, 가을파종 모두 식양토에서 가장 많았다. 수레국화의 초장은 가을 파종시 52.8~73.6 cm였고, 봄파종은 35.5~79.2cm 로 파종시기보다는 토성간에 차이가 더 컸다. 수레국화의 개화시기는 가을 파종시 5월 17~20일이었고 봄파종은 6월 19~20일로 가을 파종했을 때 약 30일정도 빨랐다. 수레국화의 부위별 질소함량은 잎에서 가장 많았으며 개화시기별로는 개화 직전에 $21.9g\;kg^{-1}$로 가장 높았으나 개화 이후 점차 감소되었다. 수레국화가 개화된 이후 이용할 경우 봄파종보다는 가을 파종할 때 더 다양한 후작물과 조합이 가능하였다. 따라서, 녹비수량, 개화시기, 후작물과의 작부체계를 기준으로 볼 때 수레국화는 가을에 파종하여 이용하는 것이 더 유리하였다.

  • Yuchang(喩昌), prominent doctor in the early days of Cheong Dynasty, argued in favor of Daegiron(大氣論) and Chujoron(秋燥論). He referred the concept of Daegi(大氣) to the initiatory force that maintains and perpetuates the vital activities of human body. The historical background of his argument can be related to the abuses of the doctrine of warming and tonifying. At that time, the practice of misusing warming and tonifying herbal medicines without deteriorations of a case was widespread among doctors. Dryness and heat disease mechanism was triggered from this malpractice. Subsequently Yuchang(喩昌) witnessed many cases of lung diseases resulting from dryness and heat. That's why he suggested relieving dryness of the lung as a treatment, further establishing Daegi(大氣) - which correlates with the lung - as the vital fundamentals. Yuchang(喩昌)'s argues that the autumn energy emanates after the Autumn Equinox and that is what Chujo(秋燥) signifies in Chujoron(秋燥論). He articulates that most of the autumn diseases can be attributed to fire and heat. This argument is distinguished from the one that attributes lung diseases to coldness, thus providing an important factor in deteriorating a lung disease.

  • Nodulation phenology in relation to plant phenology, vertical distribution of nodul and root biomass in different soil, correlation between nodule and root size, and nitrogen mineralization around the rhizosphere by ion-exchange resin bag buried at 10 cm of soil were studied in Elaeagnus nmbellata (autumn-olive) stand, Korea. Nodulation appeared from spring to autumn and nodule phenology was coincided with the timing of root activity rather than that of foliation. Nodul size increased in proportion to the root size. In the sand dune with the lower root biomass, nodule appeared up to 80 cm deep in soil and the nodule biomass was 1,070 kg/ha, which was the highest value reported for several actinorhizal plants in the temperate regions. It is suggested that nodule distribution and production are mainly influenced by soil aeration among environmental factors. The higher ammonification or lower nitrification rate contrasted markedly with the earlier studies that reported lower ammonification or higher nitrification in actinorhizal plant soil. Nitrogen mineralization rate around the rhizosphere with root and nodule was characterized by higher nitrification rate than that in the control soil without root and nodule.
