This study was conducted to investigate the relationships between yearly variations of meteorological elements and yearly variations of productivity in hot pepper. In addition, correlation coefficients among the yields and yield components were used to find out the relationships between meteorological elements and productivity. Yearly variation of the mean air temperature in May and July showed large with coefficients of variation(C.V.) of 25.0,8.9%, respectively, but the variation of the duration of sunshine in May were relative small. Yield and plant height was greatly with C.V. of 7.14,11.6%, respectively, diameter of fruit showed more or less C.V. of 2.28% and length of fruit showed less variation. Correlation coefficients between maximum temperature in period of cultivation from May and yield are positively significant at the level of 1 %. Correlation Coefficients between precipitation in period of cultivation from May to August and yield are negative significant at the level of 5 and 1 %, respectively. Correlation coefficients amount the plant height, length of fruit, diameter of fruit per plant, and seed yield were positively significant at the level of 1 %, respectively.

Background: Invasive aspergillosis (IA) is associated with significant morbidity and mortality in patients with hematologic malignancies. We investigated the efficacy and safety of voriconazole (VCZ) when used as salvage therapy for IA in Korean adults with hematologic malignancies who had not responded to prior antifungal therapy. Materials and Methods: We retrospectively reviewed data, collected from January 2007 to October 2008, from patients with proven or probable cases of IA. All were probable IA cases, except for one proven case. All cases were refractory or intolerant to antifungal therapy prior to administration of VCZ. Efficacy and safety were assessed in patients treated with VCZ for more than 3 days and for more than one dose, respectively. A favorable response [complete (CR) or partial (PR)] was defined by significant improvement of all clinical symptoms, signs, and radiologic abnormalities. Results: Fifty patients who met the inclusion criteria were enrolled. There were 27 male and 23 female patients with mean age of 44.4 years (range, 15-65 years). Underlying diseases were acute leukemia (35 cases), chronic myelogenous leukemia (4 cases), myelodysplastic syndrome (3 cases), lymphoma (3 cases) and other hematologic diseases (5 cases). Twenty-two patients had received chemotherapy and 13 patients had undergone hematopoietic stem cell transplantation. The lung was the main infection site (94%) followed by the sinus (6%). Amphotericin B deoxycholate alone was the most frequent previous antifungal therapy. The mean duration of antifungal therapy prior to VCZ therapy was 13.9±8.8 days (2-44 days). The median duration of VCZ therapy was 19 days (interquartile range, 49 days). Sixteen patients (32.0%) showed favorable responses (CR:PR=8:8) at the end of VCZ therapy. The numbers of patients with stable disease, progression and death were, 6 (12%), 6 (12%) and 22 (44%) respectively. Most of those with unfavorable responses had relapsed underlying malignancies or refractory graft versus host diseases. Twelve patients developed drug-related adverse events but only one patient stopped VCZ treatment prematurely. Conclusions: VCZ demonstrated an acceptable level of toxicity in patients with hematologic malignancies but further studies are required to prove its efficacy as salvage therapy.

김치의 단맛을 내기 위하여 일반 제조에 이용되고있는 sucros 대신 xtevioside나 sorbitol과 같이 당의 종류를 달리하여 제조한 김치의 이화학적 성분, 미생물의 변화 및 관능적 특성에 미치는 영향을 조사하였다. pH와 적정산도는 stevioside와 sorbitol이 첨가된 처리구가 sucrose가 첨가된 처리구보다 산의 생성 억제 효과가 있는 것으로 나타났다. 총균수의 경우 전반적으로 당의 종류와 저장온도와는 관계없이 미생물의 생육 억제효과가 없는 것으로 나타났으나 젖산균의 경우 10℃에서는 균의 생육 억제 효과는 없는 반면 5℃에 저장한 김치의 경우 stevioside와 sorbitol이첨가된 김치는 젖산균의 생육에 억제효과가 있는 것으로 나타났다. 관능검사를 실시한 결과 stevioside 첨가된 김치 sucrose 첨가구에 비하여 기호도에서는전적으로 우수한 것으로 나타났다. Effects of sugars addition in Kimchi preparation on physiochemical characteristics, sensory evaluation of Kimchi were investigated. Sugar sources added were sucrose, stevioside and sorbitol. Changes of pH and titratable acidity in Kimchi with addition of stevioside or sorbitol were similar to ones of control Kimchi with addition of sucrose during storage at 10℃, while ones of Kimchi with addition of stevioside or sorbitol were different from control during storage at 5℃, Comparison with control Kinich, addition of stevioside or sorbitol was inhibited acid production in Kimchi during storage at 5℃. Total number of viable cells were not significantly different among those of Kimchi samples during storage at 5 and l0℃ The number of lactic acid bacteria were not significantly different among those of Kimchi samples during storage at 10℃, but ones of Kimchi with addition of stevioside or sorbitol were less than those of Kimchi with addition of sucrose during storage at 5℃. Among sweetness, taste, flavor, color, texture and overall acceptability, the results of sensory evaluation except sweetness were showed that Kimchi added with stevioside or sorbitol was superior to ones added with sucrose.

제주도 전역에서 채집한 59점의 토양시료로부터 총 938주의 방선균을 분리하였다. 분리된 각 균주의 형태적, 생리적 특성을 조사하고 이를 기준으로 속명을 동정하므로써 제주도 지역 토양 방선균의 속 다양성을 비교하였다. 그 결과 Streptomyces 속 방선균이 62.6%를 차지하였으며 Micromonospora 속은 16.4%, Nocardioform 군은 8.6%, Actinomadura 속은 2.2%, Microbispora 속은 1.0% 나머지 Streptosporangium 속은 5.9%이었다. 토양 환경별로 보면, 초지에는 Streptomyces 속과 Micromonospora 속 균주가 풍부하였고, 밭에는 Streptomyces 속과 Micromonospora 속 균주가 풍부하였고, 산림에는 Micromonospora 속과 기타 속 균주가 풍부하였으며 기타 지역과 더불어 방선균의 속 다양성이 풍부한 편이었다. 그리고 특히 자연 동굴 토양에서는 Streptomyces 속의 분포 비율이 높지 않았으며 상대적으로 Nocardioform 균주의 분포 비율이 특히 높았다. Total 938 actinomyete strains were isolated from 58 soil samples collected at Cheju island. All of these isolates were identified to the genus level based on morphological and physiological characteristics. As the result, 62.6% of those isolates were Streptomyces, 16.4% were Micromonospora, 8.6% were Nocardioform group, 2.2% were Actinomadura, 1.7% were Microbispora, 1.6% were Nocardiopsis, 1.0% were Streptosporangium, and 5.9% were the others. As the sources of soil, Streptomyces and Microbispora were abundant in grassland soil, Streptomyces and Micromonospora were abundant in field soil, and Micromonospora were abundant in forest soil. Especially, Nocardioform strains were abundant in natural caves.

0.1V강의 표면경도를 향상시키기 위해서 Boronizing처리를 실시하여 Hv=1500∼2000의 높은 경도값을 나타내는 붕화물층을 얻었다. 붕화물층의 두께와 처리시간과의 사이에는 방물선관계를 나타내었으며 붕화물층 생성 겉보기 활성화에너지는 94kJ/mol이다. 또한 900˚C, 3시간 침붕처리했을 때가 가장 높은 경도분포값을 나타내었으며 그 이상 장시간 처리하면 오히려 경도가 감소하는 경향을 나타낸다. 그리고 침붕층은 20% HCl, 20% H₂SO₄용액에서는 뛰어난 내식성을 가지나, 20% HNO₃용액에 대해서는 상대적으로 내식성이 떨어졌다. 그리고 내고온산화성은 대기중 800˚C까지는 침붕처리한 시편이 우수했으나 900˚C부터는 오히려 감소했다. To improve the surface hardness of the 0.1V steel, by Boronizing Treatment, We got boride layer showing high hardness, Hv=1500∼2000. A parabola relationship was appeared between boride layer thickness and treatment time, and apparent activation energy to form the boride layer 94kJ/mol. Moreover, We obtained the most high hardness distribution value when had the boronizing treatment for 3 hours at 900˚C. On the contrary, If we did boronizing treatment above 3 hours, the hardness appeared decreasing tendency. The boride layer had a good corrosion resistance at a solution of 20% HCl and 20% H₂SO₄, but correlatively the corrosion resistance of the boride layer was declined at a solution of 20% HNO₃. And the boronized specimen had a good high temperature oxidation resistance until 800˚C in the atmosphere but the high temperature oxidation resistance go down above 900˚C.

Does free transplanted autologous cartilage grow? Until now many autors have published different results about the growth potential of cartilage. Some authors have produced in their study that transplanted cartilages were able to grow, but others showed contradicting results. In this study, authors obtained cartilages from young rabbits'ear, 10 by 10mm in size and divided them into two groups ; the first group was cartilages with perichondrium and the second group was cartilages stripped perichondrium. We transplanted both groups of cartilages in the posterior nuchal area of rabbits. Then numbers of specimens of each group were evaluated and compared for assessment of cartilage growth. After observaton for six months, we took the cartilages from the posterior nuchal area and examined the surface area, the thickness, and the weight and finally confirmed the growth potential of the cartilage by histologic study. The results are as follows : 1, The surface area, the thickness, and the width of the transplanted cartilages were increased significantly in gross specimens and their measured values were statistically significant and cartilages with perichondrium showed more growth than cartilages stripped perichondrium 2. In histologic studies, we observed increased surface activities with numerous proliferatng cells and found no abnormal features compared with normal cartilages. Cartilages with pericondrium were thicker than cartilages with stripped perichondrium

The purpose of the present study was to investigate the effect of C-reactive protein level and related risk factors such as T-chol, TG, uric acid and albumin in middle-aged Korean men with the frequency of alcohol consumption. The subjects of the present study was 94 men of 50-years old ages men in Seoul, Korea. The subjects were classified into 3 groups by Frequencies of alcohol consumption as follows ; non-alcohol consumption group (NA), light alcohol consumption group(LA: once or twice per week), heavy alcohol consumption group(HA: drinks more than 3 times per week). The CRP and T-chol, level of HA group was higher than compared to NA group(p<.05). In terms of TG, UA and albumin concentration. there was no significant difference. however. the value of TG was slightly higher trend in the HA group. The relationship between CRP & TG, UA was shown to significantly inverse correlation and the relationship between CRP & albumin was shown to significantly reverse correlation(p<.001, respectively). From these results. there was suggested that CRP and related cardiovascular rise factors were increased with frequency of alcohol consumption and high level of blood CRP, TG, UA are potential risk factors of cardiovascular disease factors in middle-aged korean men.
