柳長杰,宋成俊 제주대학교 방사능이용연구소 1986 연구보고 Vol.2 No.-

본 연구는 Cl과 SO₄처리가 감귤품질의 指標가 되는 糖과 有機酸함량에 미치는 영향을 알아 보기 위하여 與津早生을 시험재료로 하여 遂行된 것으로, 1984년도에는 砂耕재배와 葉面施肥를 통하여 Cl과 SO₄를 처리했을 때 감귤잎중의 無機物, 糖함량이 어떻게 변하는가를 조사하였고, 1985년도에는 Cl과 SO₄를 엽면시비 했을 경우 감귤果肉중의 당과 유기산함량에 미치는 영향을 조사하였으며, 그 결과는 다음과 같다. 1. Cl과 SO₄를 엽면시비했을 경우 감귤잎중의 Cl또는 SO₄함량이 증가되었다. SO₄처리에 의해서 P, Fe의 엽중함량이 증가되었고, Cl처리에 의해서 Ca, K, Zn, Cu등의 엽중함량이 높아짐을 볼 수 있었다. 2. 사경재배시에는 Cl과 SO₄처리에 의하여 Cl과 SO₄의 엽중함량이 증가되었으며, SO₄처리에 의해서 N, Ca, Mg, Fe, Cu등의 엽중함량이 증가되었고 Cl처리에 의해서 신엽의 Fe함량이 감소되었다. 3. 사경재배시 Cl처리보다 SO₄처리를 했을 때, 신엽중의 환원당, 비환원당, 전당 함량이 증가되었다. 4. Cl과 SO₄를 엽면시비했을시, 당의 경우에는 Cl보다 SO₄처리를 했을 때 감귤과육중의 환원당, 비환원당이 증가되었는데, 당을 HPLC로 분획정량해 본 결과 fructose, glucose, sucrose 함량이 전반적으로 증가됨을 알 수 있었고, 이같은 결과가 당도증진에 기여할 것이라 생각된다. 5. 유기산의 경우를 보면, Cl과 SO₄를 엽면 시비했을 때 SO₄에 의해 과육중의 적정산, 전산함량이 감소되었고, 또한 HPLC분석에 의하면 citric acid, oxalic acid는 SO₄에 의해 감소되나 malic acid는 증가됨을 알 수 있었다. 따라서 Cl보다 SO₄처리가 감미비증가라는 감귤 품질향상 측면에서 효과가 있는 것으로 생각된다. The effect of Cl and SO₄treatment on the contents of sugars and organic acids in mandarin juice was investigated from 1984 to 1985. In 1984, Cl and SO₄were supplied by foliar spraying and the sand culture method to determine the change of inorganic elements and sugar contents in the leaves. In the second year, the contents of sugars and organic acids in the fruit juice were analyzed to determine the effect of the Cl and SO₄foliar application. 1. Separate foliar applications of Cl and SO₄increased the contents of Cl and SO₄in leaves, respectively. The P and Fe contents of leaves were higher in the SO₄treatment than in the Cl treatment but the contents of Ca, K, Zn and Cu were higher in the Cl treatment. 2. When Cl and SO₄were applied individually to the sand culture, the contents of N, Ca, Mg, Fe, and Cu as well as SO₄in leaves were higher in the SO₄treatment than in the Cl treatment. The reduction and non-reducing sugars in the leaves increased more with the SO₄treatment than with the Cl treatment. 3. The foliar application of SO₄increased the contents of reducing sugars and total sugars in the fruit juice. HPLC analysis showed that the concentrations of fructose, glucose, and sucrose in the fruit juice were higher in the SO₄ treatment than in the Cl treatment. 4. The concentrations of titratable acid and total acid in the fruit juice were lower in the foliar application of SO₄than Cl. According to HPLC anaysis, SO₄ treatment decreased the citric acid and oxalic acid contents of the fruit juice but increased the malic acid. Consequently it can be concluded that a foliar application of SO₄is preferable to Cl as it increases the ratio of sugar to organic acid in mandarin juice.

Osteoma is a benign tumor characterized by proliferation of compact or cancellous bone that may form peripherally in a periosteal location or in central position. The most common site of the peripheral osteoma in the craniofacial area is the frontal sinus, and the extremely rare site is found to be in the external maxilla. Clinically, it appears round and shows slow growth without symptoms but its large size results in facial asymmetry, tenderness and swelling. Radiologically, peripheral osteoma appears as a well-circumscribed radiopacity and histologically shows proliferation of either compact or cancellous bone. The etiology of osteoma in maxilla is uncertain, but it has been suggested that they are frequently associated with infection or trauma. The treatment is surgical excision. We report a case of peripheral osteoma on the right anterior maxilla in 53-year-old female patient who complained of cheek discomfort and tenderness. Surgical excision was performed and the patient was followed up for 7 months without recurrence.

First record of the family Cletopsyllidae (Copepoda: Harpacticoida) from Korean waters, with description of a new species

송성준,김원,황의욱 한국통합생물학회 2010 Animal cells and systems Vol.14 No.4

A new species of the Cletopsyllidae belonging to the genus Isocletopsyllus Huys and Lee, 1999 is described from the materials collected from subtidal sandy bottoms at Jeju Island and Ulleung Island, Korea. So far, only two species of the genus Isocletopsyllus, viz. I. tertius (Por, 1964) from Israel and I. quartus (Soyer, 1966) from Banyuls-sur-Mer (France) are recorded, both from the Mediterranean Ocean. The new species can be clearly distinguished from its congeners by the combination of the following characters: (1) female antennule with a large process on the outer margin of first segment, (2) caudal rami with a bulbous proximal inner expansion, and shorter than those of other species (about four times long as wide in the new species), (3) second segment of P1 exopod with a short rod-like inner seta, (4) sexual dimorphism presented in the second endopodal segment of male P2, not in exopod of P4, and (6) female P5 with a very long exopod with very short second outer seta. A table comparing the modifications of swimming legs in the family Cletopsyllidae Huys and Lee, 1999 is presented. This is the first record of this family from Korea.

同位元素를 利用한 濟州地域 水質源에 관한 硏究(Ⅵ)

정창조,안종성,유장걸,송성준 濟州大學校 放射能利用硏究所 1991 연구보고 Vol.6 No.-

中文, 大靜地域의 地下水와 湧泉水들의 鹽分含量은 西歸浦市地域의 地下水와 비슷한 경향을 보였으나 濟州市 또는 濟州北西部地域보다는 2-5배 높은 값을 보였다. 또한, 일반화학 분석방법으로 계산된 Cl/HCO₃比를 봤을 때 大靜地域 D7湧泉水와 D14, D15 地下水는 계절에 따라 약간 차이는 있으나 1.69-4.83 範圍를 보여 海水에 의해 汚染이 된다고 판단되었다. 그러나 본 地域의 地下水와 湧泉水들이 Cl 含量이 7∼50ppm範圍여서 食水로서는 양질임을 보이고 있었다. 한편, 地下水와 湧泉水의 tritium含量도 계절에 따라 그 含量이 변하여 本島의 다른 地域(濟州市, 西歸浦市, 濟州東部地域 등)의 地下水와 湧泉水의 그 含量(8∼20 TU)보다 낮은 값(0.02∼12.7TU)을 보였다. 특히 大靜地域의 D8, D11, D12, D14, D16 관정 地下水들은 다른 地下水와 湧泉水 그리고 降水보다도 낮은 값을 보였다. 이는 火山島인 濟州道가 溶岩空隙과 範理가 잘 발달이 되어 降水가 地下水로 혼입이 빠르다고 알려진 사실을 감안한다면 이들 地下水들은 降水에 의해 직접영향을 받지 않는 年齡이 오래된 地下水임을 의미하여 타地下水와는 水源이 다르다는 것을 암시한다. The salt contents of ground waters and spring waters in Chungmoon and Daijung were similar to those of Soguipo-shi area but two to five times higher than those of the north-western area of Cheju. The ratio of Cl/HCO₃determined by chemical analysis ranged from 1.69 to 4.83, though more or less changed according to seasons, indicating the possibility of sea water intrusion. But the fresh waters of the surveyed area seemed to have good quality for drinking because chloride contents were in the range of 7-50ppm. The tritium contents of groundwater and spring water were lower(0.12-12.7 TU) than those (8-20 TU) in Cheju-shi, Soguipo-shi and the eastern Cheju. Especially D8, D11, D12, D14 and D16 groundwaters gave lower tritium contents than other groundwaters or spring waters. Considering that most rain water percolates under ground very quickly due to the permeable nature of the starta, the groundwaters having low tritium content seemed to be very old ones, not affected by the rainfall directly and differed from another groundwater resources.
