We report a case of fibroma of tendon sheath developed in a 22-year-old woman. The tumor of about 5 years duration was protruding on the volar surface of her 4th finger tip. It was well-demarcated rubbery-hard, and immovable on palpation. The surface on the tumor was smooth and had some telangiectasias. It was asymptomatic and non-tender. The histopathologic findings of excised specimen revealed well-demarcated lobulated mass with widely-spacd: fibroblasts in a hyalinized collagenous matrix. The characteristic slit-like spaces were found in hypoellular and fasciitis-like region. After excision, local recurrence has not been observed for about one and a half years of follow-up period.

차나무에서 가을정지 시기가 다음해 첫물차의 생육과 품질에 미치는 영향을 구명하기 위하여 조생, 중생, 만생의 3품종에서 가을정지를 9/26, 10/6, 10/16, 10/26로 처리시기를 달리하여 생육특성과 품질을 평가하였다. 품종의 조만성에는 상관없이 모든 품종에서 가을정지 시기가 빠를수록 아장과 백아중의 증가가 빨리 진행되었다. 가을정지 시기가 빠를수록 첫물차 개엽수의 진행도 빨리 진행되어 성숙도가 높아졌으며 수량도 많아졌다. 반면에 품질면에서는 가을정지 시기가 빠를수록 품질과 정의 상관관계가 높은 전질소, 유리아미노산, 데아닌의 함량은 낮아지고 부의 상관관계가 있는 섬유소의 함량은 높아짐을 알 수 있었다. 또한 가을정지 시기를 조절함에 의해서 품종의 조만성을 극복할 수 있을 정도로 생육의 진행도를 변화시킬 수 있을 것으로 판단되었다. This study was conducted to determine the autumn skiffing time on growth and quality of first crop tea in three cultivars(Camellia Sinensis var. Sayamakaori, Yabukita, Kanayamidori). The autumn skiffings of four different times, such as 26 Sepember, 6 October, 16 October and 26 October, were conducted. According to the experiment, the earlier skiffing time was, the earlier increase pattern of bud length and bud weight in first crop tea that we could get in all tea cultivars. The result suggested that at the early skiffing time, the number of opened leaves and yield got higher. Contrarily, in a quality of first crop tea, the chemical constituents(total nitrogen, free amino acids, theanine) content that had positive correlation to green tea quality showed a lower response to earlier autumn skiffing time. But the chemical constituent(neutral detergent fiber) content that had negative correlation to green tea quality also showed a higher response. In conclusion, varying skiffing time is recognized to control growth, yield and quality of first crop tea as surpass earliness of tea cultivars.

The extractable sulfate content and sulfate adsorption capacity in soils of four Pinus densiflora stands were measured to assess the soil acidification sensitivity to acid deposition. The soluble sulfate content in organic horizon which reflects the previous deposition of sulfur oxides was much higher for Namsan and Ulsan than Kanghwa and Hongcheon. In mineral soils, however, the extractable sulfate content was the greatest for Ulsan followed by Kanghwa, Namsan and Hongcheon due to the interactive effect of previous deposition and soil adsorption of sulfate. Adsorption rates of specifically adsorbed sulfate(proportion of insoluble sulfate to total extractable sulfate) for Namsan, Kanghwa and Ulsan affected by acid deposition were 16.6%, 56.8% and 37.4%, respectively, so that the soil in Namsan had the highest acidification sensitivity to acid deposition. For sulfate adsorption isotherm(RE = mX_i - b), the significantly positive correlations between added sulfate(X_i) and adsorbed sulfate(RE) were found only in mineral soil(p$lt;0.05) over all regions. The regression coefficient(m) that means soil sulfate adsorption capacity by 0-30㎝ depth was 0.16, 0.24, 0.25 and 0.32 in mmol_c ㎏^(-1) for Namsan, Kanghwa, Ulsan and Hongcheon, respectively, indicating that soil acidification sensitivity is the highest for Namsan. The added sulfate(X_i) that could make the adsorbed sulfate(RE) null was 3.81, 2.17, 4.96 and 0.65 in mmol_c ㎏^(-1) for Namsan, Kanghwa, Ulsan and Hongcheon, respectively and the values of former three regions considerably exceeded the realistic sulfate deposition.

Pruning is one of the most effective techniques in the tea cultural practice that controls the formation of trunks and branches. In order to find out the suitable intensity and time for pruning, we had tea plants pruned at two different times varying the pruning intensity : tea plants were first pruned at a height of 50cm, 60cm, and 70cm from the surface of the earth respectively on May 30th, 2004, which was 15 days later after the first tea crop, and the second pruning was done at a height of 50cm, 55cm, 60cm, and 65cm from the surface of the earth on July 11th, 2004, 15 days later after the second tea crop. According to the experiment, the more intensive pruning was, the longer bud length and the more opened leaves we could get regardless of the time. It also showed the result that as a pruning position was lowered, the sprouting rate got higher. In addition, the first tea crop showed a lower response to higher pruning intensity, while the yield at the unit area(20cm 20cm) increased except 50cm pruning after the second tea crop. Finally, both the whole and unit area yield turned out to be low when pruned below 50cm after the second tea crop. Therefore, it is considered as a noneffective pruning condition. In conclusion, varying pruning conditions is not recognized to affect on the quality of the first tea crop, because there is no meaningful correlation between chemical component content of tea leaves and different pruning conditions.

본 연구는 차나무 교배육종 기술체계를 확립할 목적으로 차나무 교배 실생의 획득률을 높일 수 있는 기초 자료를 얻고자 수행하였으며, 차나무에서 채종된 종자의 발아온도, 저온처리 기간, 종피 처리, 침윤 기간, 저장 방법 등 몇 가지 요인이 차 종자 발아에 미치는 영향을 분석하였다. 발아온도는 Saemidori, Topyung 및 Okumidori 3품종 모두 25℃에서 발아율이 가장 높게 나타났다. 그리고 저온처리의 영향은 Saemidori와 Okumidori 두 품종 종자 모두 저온처리 기간 50일, 63일, 75일이 38일보다 발아율과 발아속도가 높게 나타났다. 자연 건조된 Topyung 종자의 경우 종피 제거처리가 발아율이 64%로 종피 부분적 파쇄와 무 처리구보다 훨씬 높았고 Saemidori 종자의 종피 제거 처리구의 최종 발아율은 83.3%로 무 처리구의 47.5%보다 높게 나타났다. 침윤 처리 실험에서 Yabukita 종자의 최종 발아율은 침윤 2, 3, 4일 후 파종된 종자가 높았고 Okumidori 종자는 침지 3, 4일 후 파종된 종자가 높았다. 종자 보관 방법에 있어서 Yabukita 종자는 습윤 보관이 건조 보관한 종자보다 발아율이 높았고 Topyung, Okumidori 종자는 두 처리구들 간에 차이가 없었다. 발아속도는 3품종의 종자에서 모두 습윤 보관의 경우 높게 나타났고 종자 생체중이 증가되었다. The study was conducted to obtain fundamental data related to efficient increase of the seedling population aiming to establish an efficient cross breeding system for tea plants. Several parameters affecting seed germination, such as germination temperature, chilling duration, seed coat treatment, imbibition duration, and storage method, were evaluated. Of germination temperature, the highest germination percentages were obtained at 25℃ for all three varieties of Saemidori, Topyung, and Okumidori. Chilling duration of 50, 63, and 75 days had higher germination percentages and speeds of germination than those of 38 days in both varieties of Saemidori and Okumidori. Final germination percentage by seed coat removal in Topyung dried naturally showed 64 %, much higher than those by partial seed coat crack and control, and that for Saemidori, 83.3%, higher than 47.5% for control. Imbibition duration of 2, 3, and 4 days in Yabukita and those of 3 and 4 days in Okumidori showed higher germination percentages than the others. Wetness of seed storage method indicated higher germination percentage than dryness in Yabukita, however there were no differences in germination percentages of Topyung and Okumidori by storage method. On the other hand, speed of germination was higher at wetness for all three varieties in accordance with increase of seed fresh weight.

This study was carried out to evaluate the effects of organic fertilizer on the growth and quality of the first crop of tea. Test plots were applied with a combination of organic fertilizers, spring fertilizer (sesame oilseed cake), and budding stage fertilizer (Guano) in February and April, and the results were compared with those of a non-treatment plot. Yield, number of new shoots, and weight of one bud were not significant amotg the treatments. However, the rate of banjhi shoot growth was clearly reduced as application time increased. Chlorophyll contents increased in April 12 days after the addition of budding stage fertilizer, which was 2 months after spring fertilizer was applied. In addition, usage of tea taste indicator compounds showed that total free amino acid and theanine contents linearly increased as application time increased, indicating that the combined application of budding stage fertilizer influenced the contents of chlorophyll and nitrogen compounds. Contribution of guano fertilizer resulted in increases in the contents of total free amino acids and theanine by 13.44 ± 4.01% and 11.81 ± 4.49%, respectively. Conclusively, this strongly suggests that Guano as budding stage fertilizer could be used as a tea taste indicator to increase the contents of total free amino acids and theanine by 10% or more.
