The gene and genotypic frequencies of ${\kappa}$-casein (${\kappa}$-CN), ${\beta}$-lactoglobulin (${\beta}$-LG), growth hormone (bGH) and prolactin (bPRL) loci in Korean cattle were investigated using PCR-RFLP analyses. Genomic DNA samples were obtained from 290 cows and 30 AI bulls. In both cows and bulls, the most predominant genotypes of ${\kappa}$-CN, ${\beta}$-LG, bGH and bPRL loci were AB, BB, AA and AA, respecitively. The frequencies of A and B alleles for ${\kappa}$-CN locus were .612 and .388 for cows and .567 and .433 for bulls. The respective frequencies of A and B alleles for ${\beta}$-LG locus were .153 and .847 in cows and .217 and .783 in bulls. The frequencies of A and B alleles for bGH locus were .769 and .231 in cows and .784 and .216 in bulls, respectively. The frequencies of A and B alleles for bPRL locus were .678 and .322 for cows and .767 and .233 for bulls. Differences in frequencies of these alleles were not significant between cows and bulls at all loci examined. If the DNA polymorphisms of these candidate genes are associated with economically important traits, they could serve as genetic markers for genetic improvement in future marker-assisted selection programs in Korean cattle.

Jinju City has been often called as the largest agglomeration of the silk industry in Korea. However Jinju's silk industry has experienced a continuous decline in employment and to production outputs after the late 1980s. This paper aims to explore innovation capacities of Jinju's silk industry and evaluate the government policy to promote the competitiveness of the silk industry in Jinju. The main findings are as follows. First, the survey shows that the major sources of innovation tend to come from customer firms in the Capital area and the innovation supporting agency and universities in Jinju City. Second, local silk production firms tend to by and large evaluate that the industrial policy projects to promote the competitiveness of Jinju's silk industry have been successful, particularly in terms of a joint branding project and the marketing support program.

Purpose: Determining the spatial structure of data is important in understanding within-field variability for site-specific crop management. An understanding of the spatial structures present in the data may help illuminate interrelationships that are important in subsequent explanatory analyses, especially when site variables are correlated or are a combined response to multiple causative factors. Methods: In this study, correlation, principal component analysis, and single and nested variogram models were applied to soil electrical conductivity and chemical property data of two fields in central Missouri, USA. Results: Some variables that were highly correlated, or were strongly expressed in the same principal component, exhibited similar spatial ranges when fitted with a single variogram model. However, single variogram results were dependent on the active lag distance used, with short distances (30 m) required to fit short-range variability. Longer active lag distances only revealed long-range spatial components. Nested models generally yielded a better fit than single models for sensor-based conductivity data, where multiple scales of spatial structure were apparent. Gaussian-spherical nested models fit well to the data at both short (30 m) and long (300 m) active lag distances, generally capturing both short-range and long-range spatial components. As soil conductivity relates strongly to profile texture, we hypothesize that the short-range components may relate to the scale of erosion processes, while the long-range components are indicative of the scale of landscape morphology. Conclusion: In this study, we investigated the effect of changing active lag distance on the calculation of the range parameter. Future work investigating scale effects on other variogram parameters, including nugget and sill variances, may lead to better model selection and interpretation. Once this is achieved, separation of nested spatial components by factorial kriging may help to better define the correlations existing between spatial datasets.

A simple and specific method for determination of methyltestosterone (MT) has been established by a gas chromatography/mass selective detector and applied in plasma of healthy male volunteers received a single oral dose of 50 mg MT $(Testo^{TM}\;tablets,\;25\;mg)$ for bioavailability test. This method involves using liquid-liquid extraction of the sample with diethyl ether and derivatization with MSTFA. MT showed good resolution in this condition. The detection limit of quantitation was 5 ng/ml. A good linearity (r>0.996) was obtained at the range of 5-250 ng/ml of MT. Intra-day precision and accuracy were 2.76-12.56% and 0.39-8.01 %, and inter-day precision and accuracy were 2.29-17.69% and 0.42-7.99%, respectively. The established method was applied on bioavailability test of MT in human volunteers. The value of $AUC_{0\;to\;last}$ to last was $264.5{\pm}123.9\;ng{\cdot}hr/ml$ and that of $AUC_{0\;to\;inf}$ was determined to be $275.2{\pm}126.5\;ng{\cdot}hr/ml$. The values of $C_{max}$ and $T_{max}$ were $95.9{\pm}67.1\;ng/ml$ and $1.13{\pm}0.9\;hr$, respectively. The mean elimination half-life $(t_{1/2})$ was $4.4{\pm}0.9\;hr$. This analytical method is suitable and useful for the pharmacokinetics and bioequivalence studies of MT.

We measured and evaluated digital, pre-sampling and overall imaging properties (characteristic curves, Modulation Transfer Function (MTF), Wiener spectra (WS), Noise Equivalent Quanta (NEQ) and Detective Quantum Efficiency (DQE)) for the direct type and indirect type of Flat-Panel Detector (FPD). First, the digital and overall characteristic curves of the both types of FPD had more wide dynamic range than that of the S/F system. Second, the pre-sampling and overall MTF of the direct-type FPD were superior to those of the indirect-type FPD. Third, for identical exposures, the digital and overall WS of the direct-type FPD were similar or worse than those of the indirect-type FPD, and for larger exposure, the digital WS of the both types of FPD were smaller, but overall WS of the both types of FPD were larger. Fourth, the digital and overall NEQ and DQE of the direct-type FPD were worse than both NEQ and DQE of the indirect-type FPD at lower spatial frequencies, but were better at higher spatial frequencies.

The purpose of this study was to compare the consciousness of health status and nutrient intake of farmers in Korea. Eight hundred were surveyed by rural leaders of Rural Development Administration(RDA), composed of 35.1 % male and 64.9% female. Data collection included personal & family situation by Interview method for influencial factors of health status. Food intake was determined by semiquantitative food frequency method with 65 kinds of foods. 32.5% of the subjects were elementary school graduates, younger age groups and males had higher levels of education. Mean family numbers was 4.2 persons. In the concept of disease prevalence, gender difference existed. Liver and heart ailments were frequent in males and waist pain and urinary complaints in females, and schoulder pain and nervesness were frequently prevalent to all farmers. The energy intake of farmers was 2000Kca1/day, 19:16:65 of PFC(protein, fat, and carbohydrate) ratio was approached at recommended composition of energy. But calcium and iron were lower than Korean Recommended Dietary Allowences(KRDA), Vitamin A, thiamin, niacin, and vitamin C were over of KRDA, but riboflavin, pyridoxin, and vitamin I were lower than KRDA. The nutrient intakes of poor health groups were significantly lower than those of healthy. In fatty acid composition, monounsaturated fatty acids(FA) intake was higher than that of saturated FA. The CMI (Cornell Medical Index) and Farmers' syndrome were significantly correlated with personal factors, such as height, number in family, education level, and working level. But the correlation of health status with nutrient intakes were only weakly significant. Depending on the regression analysis, Farmers' syndrome explanation about nutrient intake was low(R2 was only 0.01 more or less), but some nutrients (energy, niacin, pyridoxine, vitamin E, and lipids) could explain this significantly. It was concluded that body complaints of farmers could ameliorate with good nutrition.

Rancidity of a soybean oil is investigated by an electrochmical method. The redox process of the soybean oil is totally irreversible and diffusion-controlled reaction. As scan rates are faster, the anodic peak potential of the soybean oil is shifted to the positive potential and the anodic current is increased. The anodic peak potentials of the soybean oil is not rarely changed up to open-42 days in the both atmosphere and room temperature. After the open times, the anodic peak potential is largely shifted to a negative direction. This indicates the oxidation of the soybean oil becomes easier. The anodic peak current of the soybean oil is decreased gradually up to open-42 days. But after the open times, the anodic peak current increases suddenly. It must be due to the formation of a carbonyl group owing to rancidity of the soybean oil.

An X-linked skeletal disorder, SEDT (spondyloepiphyseal dysplasia tarda) is a genetic disease characterized by a disproportionately short trunk and short stature caused by mutations in the SEDL gene. This gene is evolutionarily conserved from yeast to human. The yeast SEDL protein ortholog, Trs20p, has been isolated as a member of a large multi-protein complex called the transport protein particle (TRAPP), which is involved in endoplasmic reticulum (ER)-to-Golgi transport. The interaction between SEDL and partner proteins is important in order to understand the molecular mechanism of SEDL functions. We isolated several SEDL-binding proteins derived from rat cells by an immobilized GST-fusion method. Furthermore, the SEDL-homologue proteins were identified using motif based methods. Common motifs between SEDL-binding proteins and SEDL-homologue proteins were classified into seven types and 78 common motifs were revealed. Sequence similarities were contracted to seven types using phylogenetic trees. In general, types I-III and VI were classified as having the function of acetyl-CoA carboxylase, glycogen phosphorylase, isocitrate dehydrogenase, and enolase, respectively, and type IV was found to be functionally related to the GST protein. Types V and VII were found to contribute to TRAPP vesicle trafficking.
