In this paper, we describe our study on the characterization of tobacco leaves by their pyrolysis patterns. Two kinds of tobacco leaves were pyrolyzed and analyzed by Double-Shot Pyrolysis-Gas Chromatography/Mass Spectroscopy (Py-GC/MS) methods. Three grades of Korean flue-cured tobacco leafsuch as B1O, AB3O, CD3L and burley tobacco leaves such as B1T, AB3T, CD3W were pyrolyzed with six discrete but stepwise heating temperature ranges, those are from 100$^{\circ}C$ to 150$^{\circ}C$, 150$^{\circ}C$ to 200$^{\circ}C$, 200$^{\circ}C$ to 250$^{\circ}C$, 250$^{\circ}C$ to 300$^{\circ}C$, 300$^{\circ}C$ to 350$^{\circ}C$ and finally from 350$^{\circ}C$ to 400$^{\circ}C$. Using the resultant 52 pyrolytic components identified in the programs as components, principal component analysis (PCA) showed statistical classification between flue-cured and burley tobacco lamina. Among six pyrolysis temperature ranges, the best discrimination was achieved at the temperature range from 250$^{\circ}C$ to 300$^{\circ}C$ and from 300$^{\circ}C$ to 350$^{\circ}C$.

Objectives: This study aimed to investigate gender differences in the Korean Medical Community. Methods: Participants in the research study included 90 students regularly attending the fourth grade in Korean Medicine College, of which 48 were male and 42 were female. Results: 1. Patient's preferences for female KMD (Korean Medicine Doctor) had the lowest response rate in Korean Medical Society. Preferences for male KMD were due to factors including comfort level, rationality, good training, and patient's preference. 2. Patient's preferences for female KMD had the highest response rate in Gynecology, and Pediatrics. On the other hand, patient's preferences for female KMD had the lowest response rate in the other 7 specialty subjects. 3. The reasons for gender discrimination against male KMD were lack of subtlety, lack of empathy, authoritative attitude, and lack of patient management skills. The reasons for gender discrimination, against female KMD were childcare burden, social prejudices, lack of physical strength, and housekeeping burdens. Conclusions: The study results indicated that there was a lower preference for female KMD than male KMD among the Korean Medical Society and in patients' consciousness. Male-centered culture of Korean Medical Society had no role in this finding, but masculine image for KMD jobs and work-family double burden for female KMD were important contributing factors.

The identification of the DNA structure as a double-stranded helix consting of two nucleotide chain molecules was a milestone in modern molecular biology. The DNA chip technology is based on reverse hybridization that follows the principle of complementary binding of double-stranded DNA. DNA chip can be described as the deposition of defined nucleic acid sequences, probes, on a solid substrate to form a regular array of elements that are available for hybridization to complementary nucleic acids, targets. DNA chips based on cDNA clons, oligonucleotides and genomic clons have been developed for gene expression studies, genetic variation analysis and genomic changes associated with disease including cancers and genetic diseases. DNA chips for gene expression profiling can be used for functional analysis in human eel Is and animal models, disease-related gene studies, assessment of gene therapy, assessment of genetically modified food, and research for drug discovery. DNA chips for genetic variation detection can be used for the detection of mutations or chromosomal abnormalities in cnacers, drug resistances in cancer cells or pathogenic microbes, histocompatibility analysis for transplantation, individual identification for forensic medicine, and detection and discrimination of pathogenic microbes. The DNA chip will be generalized as a useful tool in clinical diagnostics in near future. Lab-on-a chip and informatics will facilitate the development of a variety of DNA chips for diagnostic purpose.

In the absence of the alternative public space of women in Japan, the experience of the "Bongseonhwa" was interpreted as the public domain of Japanese society as a public domain, a confession that focused on gender discrimination in the patriarchal system of Japan, Most of the enemy discourse is. These alienated discourses are the product of the efforts of women in Japan who do not want to forget about the traces and memories that can not be incorporated into the big narrative. It can not be denied that the women in the society of Japan have been excessively excluded and alienated by national ideology and patriarchal ideology. The meaning of presenting them through "Bongsinghwa" is the resistance of the minority, and it is the expression way of reconstructing and strengthening the identity of the women, and it is said to be a space of symbolic meaning. It is further clarified that it is based on a narrative that creates a new life area for coexistence with Japanese society, on the other hand, by constantly searching for the linkage with the motherland, held by women in Japan. As a result, between public social phenomena and private living space, confirmed that it conflicts with repetitive internal contradiction of controlling power and confirmed that complicated and detailed material of women living in Japan who undergo double discrimination What has been expressed over a period is considered to be a resistance expression and a will of expression of reconciliation to coexist with Japanese society. I have attempted to analyze the confessed alienated discourse of "Bongsinghwa" by classifying it as . As a result, it is confirmed that the public social phenomenon and the private life space are confronted with the repetitive internal contradictions of the power of domination, and the expression of the complex and detailed material of the discriminated women in Japan over a long period of time is a resistance to symbiosis with Japanese society And the will of the conversation.

An electromagnetic flowmeter(EMF) was developed and its characteristics were compared with a commercial EMF. The developed EMF was designed as the 100 mm nominal diameter. A signal processing circuit was also developed for generating the magnetic field and converting the flow signal to flowrate and flow quantity. In order to obtain a more stable and reliable flow signal, the double magnetizing frequency was adopted for magnetizing the coil of the EMF. For the characterization of the developed EMF, the uncertainty of calibrator was estimated within $\pm$0.5 %. The evaluation procedure of the uncertainty followed the ISO Guide to the Expression of Uncertainty in Measurement. It was found that the flow signals between the electrodes were about $\pm$60-$\pm$300$\mu$V, which were sufficient for the discrimination of flowmeter and the protection of noise. The test results against the calibrator showed the good linearity in the range of 3 ㎥/h and 70 ㎥/h. A commercialized design of the EMF based on the current study will be technically more competitive in domestic and foreign market.

Purpose : Loss of sensibility over the finger tip resents a grave deficit and is an indication for sensible soft tissue reconstruction. This paper was performed to assess the long term results obtained by nerovascular island flap. Material and Methods : We performed neurovascular island graft for defective sensibility of finger tip loss in 94 cases since 1979 to 2000. The recipient sites were the thumb pulp defect in 79 cases, the amputated thumb in 9 cases, the amputated index in 4 cases, and the velar aspect of interphalangeal joint of thumb in 2 cases. The donor flaps were obtained from the radial side of ring finger in 63 cases, the ulnar side of the ring finger in 21 cases, and the ulnar side of the middle finger in 10 cases. A mean follow-up period was 5.7 years. Results : The flap quality was well vascularized and survived in 89 cases. The two-point discrimination was average 8.7mm. Because of scar contracture, the range of motion of the donor finger was decreased 3.5% of the normal finger in the distal interphalangeal joint, 8,2% in the proximal interphalangeal joint. A phenomenon of double sensibility occurred in 66 cases. Conclusion : This technique was excellent both aesthetically and functionally as a reconstruction of the Loss of fingertip.

This paper serves to analyze discourses on concubine at the beginning of the modernization era or during the enlightenment period of Korea. For this analysis, the estimated time frame of the enlightenment period will be from 1860 through the time when Korea was annexed into Japan, which was in 1910. The discourses appeared in newspapers and Shinsoseol which are the text of this study have been analyzed with the qualitative research technique. The major conclusions that are derived from the study are as follows: First, intellectuals during enlightenment period of Korea, criticizing concubinage, tired to establish the monogamous relationship and they argued that it should be the prior condition for Korea to enter into the civilized society. Second, the concubinage was criticized in the point of the newly established view. The criticism was on double sex ethics, applying different ethical standards to men and women and the prohibition of wifes jealousy of concubine. Third, intellectuals during enlightenment period of Korea were tried to do away with concubinage by enforcing the discrimination between wife and concubine. But the efforts resulted in making concubinage personal problems. Also consciousness based confucian ethics including female virtues was forced to be followed in ordinary affairs while concubinage was criticized in the point of the view of western ethics based consciousness. The huge differences between two ethics consciousness resulted in serious conflicts in family.

This essay examines Toni Morrison's African-American characters' struggle in The Bluest Eye (1970) and Home (2012) through the lens of heteronormativity, arguing that they suffer double victimization due to both their race and gender. The Bluest Eye portrays a family tragedy caused by an African-American husband and wife's failure to live up to images of gender as represented in white, middle-class media. Written forty-two years later, Home describes an African-American man and woman who establish their own lives away from gendered standards after striving to meet social expectations and becoming traumatized in the process. Their adversities stem not only from the deeply rooted racial discrimination in American society but also from subtle gendered norms implanted by heteronormativity. Morrison's characters in her earlier narrative face a tragic denouement, ultimately destroying their children's lives. By contrast, Morrison's later characters explore more utopian ways of life unfettered by heteronormativity, overcoming hardships imposed by white-centered heteronormal society. By portraying socially victimized characters, Toni Morrison problematizes the power behind the discriminatory nature of heteronormativity and suggests a more gender-neutral, egalitarian way of organizing society, free from the constraints of heterosexuality and from violence created by normalized gender rules.

With a double mismatch primer set designed for amplifying the modified DNA sequence fragments, bovine melanocortin-1 receptor(MC1R) gene encoded in Extension locus which plays a critical role in coat color development was analyzed using polymerase chain reaction mediated restriction fragment length polymorphism(PCR-RFLP). Amplified PCR fragments were successfully discriminated with combining the MspI- and AluI-RFLP into three major alleles(ED, E+, and e), directly related to bovine coat color phenotypes. The genotyping results showed that Jeju black cattle contained three MC1R alleles, but yellowish-red colored Hanwoo and bridle colored Korean Brindle cattle did not contained the dominant black allele ED. However, two dominant black-colored cattle breeds, Holstein and Angus, contained the ED allele over 96% in frequency. Hanwoo×Holstein F1 and Hanwoo×Angus F1 crossbred calves showed ED/e MC1R genotypes, and uniformly black coat color. the results suggested that this MC1R genotyping method be useful in allele discrimination for bovine MC1R gene which used for breed classification and characterization, as one of the important genetic markers, using combination of MspI- and AluI-RFLP for modified PCR product amplified with a newly designed double mismatch primer set.
