We report on comparative results obtained from harmonically mode-locked laser operations of ring-type and figure-of-eight(F8) type erbium-doped fiber lasers by using a directional-coupler type electro-optic modulator as an active mode-locker. The mode-locked and transform-limited pulses of 10.6 ps width were obtained at harmonics of the fundamental cavity frequency with the F8 type laser while mode-locked laser pulses greater than 15 ps were achieved with the ring type laser.

본 연구에서는 건강한 한국인 분변으로부터 Senegalimassilia sp. KGMB 04484 균주를 분리하였으며 PacBio Sequel 플랫폼을 이용하여 유전체서열을 분석하였다. 유전체는 G+C 구성비율이 61.18%이며, 2,300개의 유전자와 2,139개의 단백질 코딩 유전자, 21개의 rRNA 및 51개 tRNA로 구성되었으며, 염색체의 크기는 2,748,041 bp였다. 유전체의 주요 특징은 가수분해효소와 지방산생합성 및 대사에 관련된 유전자를 포함한다. 이러한 유전체의 분석은 KGMB 04484 균주가 사람의 건강 및 소화에 관여할 것으로 여겨진다.

This feeding experiment was conducted to investigate the effects of slurry type diet on growth performance and survival rate of growing leptocephalus, eel larva. We need to find new materials of diets for rearing eel larvae. Test diets were formulated with the eggs of the shark, fish soluble concentrate, soybean peptide and fish protein hydrolysate. Fish (average length 6 mm) were fed 3 slurry type diet(A, B and C) based on shark egg for 5 times per day. During feeding experiment, survival rates were significantly different among 3 slurry type diets. Total protein, lipid, moisture, ash and free amino acids contents were analyzed for slurry type diets. Leptocephalus fed the C slurry type diet was grown up to $38.0{\pm}9mm$ at 150 days. But all leptocephalus fed B slurry type diet were died at 100 days, reaching $16.4{\pm}8mm$. This results suggest that basic information for diet development of eel leptocephalus.

In this paper, low noise amplifiers with coplanar waveguide structure are presented for Wireless LAN data communication application. For comparison of microwave performance, LNAs of cascode type and balanced type using cascode cell with the same substrate and same bias conditions are designed and implemented. A cascode type of LNA shows the gain of 12.45 ㏈, input return loss of 11.63 ㏈, and noise figure of 1.52㏈. A balanced type of LNA using cascode cell shows the gain of 6.58 ㏈, input return loss of 16.6 ㏈, and noise figure of 1.18 ㏈.

One hundred and eighty two lactic acid bacteria, isolated mainly from kimchi, including reference strains were examined for their ability to utilize 95 carbon sources. The test strains were assigned to 5 major, 1 minor and 12 single-membered clusters based on the $S_{SM}$, UPGMA algorithm (at similarity of $80{\%}$). These aggregate clusters were equivalent to the genus Leuconostoc (aggregate cluster M and N), the genus Lactobacillus (aggregate cluster Q and R), and the genera Lactobacillus and Leuconostoc (aggregate cluster O and P) according to the database of the Biolog system. This study demonstrates that rapid identification and classification of isolates originating from kimchi can be achieved on the basis of such carbon source utilization tests.

Endobronchial tuberculosis is a serious disease which is frequently complicated with bronchial stenosis, and it may simulate a bronchial asthma or bronchogenic carcinoma. We have analyzed the clinical characteristics of endobronchial tuberculosis in 166 patients, and we introduce new classification of endobronchial tuberculosis. Endobronchial tuberculosis is classified into seven subtypes as stenotic type with fibrosis, stenotic type without fibrosis, actively caseating type, tumorous type, ulcerative type, granular type and nonspecific bronchitic type, according to the bronchoscopic findings. Actively caseaing type, stenotic type without fibrosis, nonspecific bronchitic type and stenotic type with fibrosis are predominant in the order of frequency, but ulcerative type and granular type are relatively rare. Stenotic type with or without fibrosis, actively caseating type and tumorous type of endobronchial tuberculosis are closely related to bronchial stenoses. We believe that our new classification of endobronchial tuberculosis, which is based on bronchoscopic features, is helpful to understand the pathogenesis of disease and to make a therapeutic plan for preventing or minimizing bronchial stenosis.

Purpose: This study was conducted to develop an optimal combine scheduling program using Max-Coverage algorithm which derives the maximum efficiency for a specific location in harvest seasons. Methods: The combine scheduling program was operated with information about combine specification and farmland. Four operating types (Max-Coverage algorithm type, Boustrophedon path type, max quality value type, and max area type) were selected to compare quality and working capacity. Result: The working time of Max-Coverage algorithm type was shorter than others, and the total quality value of Max-Coverage algorithm and max quality value type were higher than others. Conclusion: The developed combine scheduling program using Max-Coverage algorithm will provide optimal operation and maximum quality in a limited area and time.
