Five barley crosses and their progenies (F$_2$, F$_3$, and F$_4$) were evaluated the potentiality of hybrid populations to segregate superior yielders in later generation. Four characters used for evaluation were number of spike, number of grain, spike weight and grain weight per plant. Superiority value (Y) of number of spike was best in SB76588${\times}$SB72648 and average of superior plants in F$_4$, was excellent in this cross. Milyang 6${\times}$Suwon 203 showed high Y value and average of F$_4$ superior plants in the number of grain. Spike weight showed the highest Y value and excellent averages of superior plant in Milyang 6${\times}$Suwon 203. Superiority value of grain weight per plant coincided with average of F$_4$ superior plants in 3 crosses and SB76588${\times}$SB72648 was the best among the crosses.

In previous paper, we isolated the bacteria, Bacillus subtilis JM-3, with proteolytic and fibrinolytic activity for candidate microorganisms that have rapid fermenting and physiological functions from anchovy sauce. This study was carried out to search physiological functions of Bacillus subtilis JM-3, such as antimicrobial, antioxidative, antimutagenic, angiotensin-converting enzyme inhibition, and anticarcinogenic activity in vitro. The cell free culture of Bacillus subtilis JM-3 showed strong antibacterial activity against Listeria monocytogenes, antioxidative activity with 87% of inhibition rate against linoleic acid, 50% of antimutagenic activity against N-nitrosodimethylamine and N-nitrosomorpholine, and 88.9% of growth inhibition rate against SNU-1 cell line (stomach cancer cell of human). However, Bacillus subtilis JM-3 did not show angiotensin-converting enzyme inhibition activity.

In this paper, a vital signal sensor based on impedance variation of resonator is presented. Proposed vital signal sensor can detect the vital signal, such as respiration and heart-beat signal. System is composed of resonator, oscillator, surface acoustic wave (SAW) filter, and power detector. The cyclical movement of a dielectric such as a human body, causes the impedance variation of resonator within the near-field range. So oscillator's oscillation frequency variation is effected on resonator's resonant frequency. SAW filter's skirt characteristic of frequency response can be transformed a small amount of frequency deviation to a large variation. Aim to enhance the existing sensor detection range, proposed sensor operates in 870 MHz ISM band, and detect respiration and heart-beat signal at distance of 120 mm.

SoP-L 공정은 유전율이 상이한 재료를 이용하여 PCB 공정이 가능하고 다른 packaging 방법에 비해 공정 시간과 비용이 절약되는 잠정이 있다. 본 연구에서는 SoP-L 기술을 이용하여 Si 기판의 함몰에 판한 공정의 안정도와 함몰 시 제작된 때턴의 특성의 변화에 대해 관찰 하였다. Si 기판의 함몰에 Active device를 이용하여 특성의 변화를 살펴보고 공정의 안정도를 확립하려 했지만 Active device는 측정 시 bias의 확보와 특성의 민감한 변화로 인해 비교적 측정이 용이하고 공정의 test 지표를 삼기 위해 passive device 를 구현하여 함몰해 보았다. Passive device 의 제작 과정은 Si 기판 위에 spin coating을 통해 PI(Poly Imide)를 10um로 적층한 후에 Cr과 Au를 seed layer로 증착을 하였다. 그리고 photo lithography 공정을 통하여 photo resister patterning 후에 전해 Cu 도금을 거쳐 CPW 구조로 $50{\Omega}$ line 과 inductor를 형성하였다. 제작 된 passive device의 함몰 전 특성 추출 data와 SoP-L공정을 통한 함몰 후 추출 data 비교를 통해 특성의 변화와 공정의 안정도를 확립하였다. 차후 안정된 SoP-L 공정을 이용하여 Active device를 함몰 한다면 특성의 변화 없이 size 룰 줄이는 효과와 외부 자극에 신뢰도가 강한 기판이 제작 될 것으로 예상된다.

A new Cymbidium cultivar 'White Princess' was released by the National Horticultural Research Institute (NHRI) in 2005. A cross was made in 1995 between 'Cymbidium 2113', light purple colored petal and medium plant sized variety, and 'Lucky Rainbow Randevous', a dark purple petal with red lip and large type variety. The ninety progenies were obtained after planting and acclimatization in green house. In 2000, a line (9526747) was selected and multipliticed after test of its flower color, leaf shape, flower stalk, and vigorous growing habit. After evaluation trial for two growing seasons, the selected line was named as 'White Princess'. The 'White Princess' has white petals (WN 155A) with red lip (RP59D) color and large sized leaves, and flowers (leaf length is about 88 cm and flower diameter is about 8 cm) with semi-erect flower stalks. Blooming started from December to January in optimal culture conditions. High temperature (more than $30^{\circ}C$) and low light intensity(less than 10,000Lux) should be avoided for the appropriate growth.

The component and content of free sugar in mulberry fruits were evaluated. In all accessions, fructose and glucose were identified as the major free sugar. The ratio of two components appeared in the same level. But CV (coefficient of variation. ％) of fructose and glucose were 23.6％, 23.4％, respectively. It might suggest that varietal variation exists in sugar contents. The mean of total free sugars were 9.11${\pm}$2.14％. Among the tested 49 accessions, ‘Geunanosang’ showed the highest total free sugars in 14.67％, whereas ‘Cheongsipyung’ showed the lowest total free sugars in 5.57％. Also fruity characteristics as well as total free sugars to select the desirable mulberry varieties for the production of fruit were researched and analyzed. From that results, four suitable varieties such as ‘Hwansipchosaeng’, ‘Junggojo’, ‘ Kaery-angchosaengsipmunja’, and ‘Geunanosang’ were selected.

Fatty acid composition is an important economic trait that affects meat flavor. Several genes that influence fatty acid composition in meat have been investigated. In a previous study, we identified 51 significant SNP × SNP interactions (P≤0.05) between nine SNPs of six candidate genes (DEGS1, ELOVL6, FABP3, FABP4, FASN, and SCD) on meat fatty acid composition in Korean native chicken. This study further investigated the patterns of the SNP × SNP interactions to understand how they affect the fatty acid content in thigh and breast meat of Korean native chicken. The significant epistatic effects of SNP combinations showed various patterns for each fatty acid trait. The results of this study suggest that the respective additive effects of each SNP on polygenic traits, such as fatty acid composition, should be considered in combination with the epistatic effect of SNP combinations in animal breeding programs. The findings of this study have provided new genetic information for improving meat quality, especially the fatty acid composition, of Korean native chicken.

This study was carried out to obtain basic genetic informations in pea(Pisum sativum L.). A series of field experiments were carried out with seven pea cultivars and F$_1$ hybrids for three years. Based on the information collected from a set of diallel crosses, the behaviours of inheritance of seed yield and ten major agronomical characters were observed by the estimation of heterosis and combining ability. Heterosis for seed yield per plant was 79% and those for yield components such as number of seeds per plant, number of pods per plant, stem length, stem diameter, number of branches per plant, also showed relatively high values. General combining ability(GCA) and specific combining ability(SCA) were significantly different among major agronomic characters, and the variances of GCA were higher than those of SCA latter. Among the tested cultivars, Alderman was found to be the most promising parent based upon the GCA effects on the seed yield and yield components. The crosses of Sugar Ann$\times$Alderman, Wando$\times$Alderman and JI 1198$\times$Chinju ＃6, showed the highest SCA effects on seed yield and yield components.

This study was investigated to know the possible linkage relationship between blast resistance gene and plant height gene in rice. Two resistant varieties, Tadukan and Tetep were crossed with six susceptible semi-dwarf tester lines. Progenies derived from the crosses were inoculated with spray method at 3-4 leaf stage with blast races, C-8$^{+t}$ and T-2$^{+t}$. The results indicated that: (1) Resistance of Tadukan and Tetep to the C-8$^{+t}$ was controlled by a single dominant gene, respectively. (2) Resistance of Tadukan and Tetep to the T-2$^{+t}$ was expressed by complementary gene action between two dominant genes, respectively. (3) No linkage relationship was found between resistance gene and plant height gene of both Tadukan and Tetep when tested with C-8$^{+t}$ and T-2$^{+t}$, respectively.espectively.
