In this paper, an algorithm for a real-time automatic fingerprint identification system is proposed. The fingerprint feature volume is extracted by considering distinct and local characteristics(such as intensity and image quality difference etc.) in fingerprint images, which makes the algorithm properly adaptive to various image acquisitionj methods. Also the matching technique is designed to be invariant on rotation, scaling and translation (RST) changes while being capable of real-time processing. And the classification of fingerprints is performed based on the ridge flow and the relations among singular points such as cores and deltas. The developed fingerprint identification algorithm has been applied to various sets of fingerprint images such as one from NIST(National Institute of Standards and Technology, USA), a pressed fingerprint database constructed according to Korean population distributions in sex, ages and jobs, and a set of rolled-than-scanned fingerprint images. The overall performance of the algorithm has been analyzed and evaluated to the false rejection ratio of 0.07% while holding the false acceptance ratio of 0%.

As evidence that can be obtained at the crime scene, the importance of micro-evidences has been recognized in recent years with the development modern molecular-level analytical techniques. These micro-evidences include substances useful for personal identification such as DNA, but it is difficult to collect only the evidences showing individual characteristics every time at the crime scene. Therefore, development of new research approaches for the discovery and application of micro-evidence candidates is in increasing demand. For this purpose, skin microbial communities of bacteria inhabiting the palms of 16 people were collected and terminal-restriction enzyme fragment length polymorphism (T-RFLP) analysis was carried out to examine the potential for the application in personal identification. As a result, 16 different electropherograms were obtained, and various taxa including Staphylococcus and Bacillus were shown to produce different T-RF profiles among individuals. These results were analyzed with the factors affecting the microbiota such as sex and working environment of individuals.

IGF-I is involved in the regulation of growth and differentiation in mammals, but its role as a modulator of growth and metabolism in poultry is poorly understood. And, no studies have so far been reported for the comparison between serum IGF-I concentration and body growth in the egg type or the dual purposes (meat and egg type) chicken including the Korean Native Ogol Chicken (KNOC). Therefore, in order to improve the body growth and meat production of the KNOC, this study was conducted for the identification of the polymorphism of IGF-I gene and for its possible association with both body weight and IGF-I concentration. The RFLP patterns for IGF-I gene were identified by the PstI restriction enzyme. The frequencies of +/+, +/-, and -/- genotype were 16.9%, 51.7%, and 31.4%, respectively. Any statistical significance was not observed in all variations except for sex variation (p<0.01) by covariate quadratic model. The significant effect of the IGF-I genotype on body weight by sex indicates that there are different physiological characteristics in gender. Although the body weights of male KNOCs in most ages were not significant, there was a tendency of KNOCs with +/+ IGF-I genotype to be heavier than those with any other genotypes. But all IGF-I genotypes in female did not influence on body weight. The ANOYA revealed no significant effects of IGF-I genotypes on serum IGF-I concentration but sex effect was highly significant on the IGF-I concentration at 20 and 40 weeks (p<0.01). Although the +/+ genotype, in gender, tended to express a higher IGF-I concentration than the other genotypes at all ages in males, a statistical difference among the genotypes was not found except for 60 weeks (p<0.05). Furthermore, since body weight and IGF-I genotypes are associated, it is possible to improve KNOC to a meat type breed if a continuous selection can be made for the body weight and/or IGF-I traits.

The purpose of this study is to prevent and review counter-action for the sexual harassment in campus by revealing current state of sexual harassment in campus relatively weak in sexual discrimination with regard to sexual harassment emerged as social problem serious in our nation. The targets of study were students and assistants in three schools located at $Kwangju\cdot{Chonnam}$ area, a questionnaire made by pre-researcher was applied to student vs. assistant with regard to sexual consciousness and recognition, and current state of sexual harassment, with analysis of material processed through statistical analysis using SPSSWIN 10.0 for verification of $$\chi$^2$ for identification of difference vs. family and student vs. assistant. The result of this research with regard to sexual harassment is under following: Firstly, the recognition of concept of sexual harassment was proved to be aware of be more than half a responders above average, lack of recognition showed significant number requiring establishment of concept of sexual harassment, the responders stated that they could do it alone should be treated in the counseling room in school. Secondly, 28.7% of students and assistants answered that they have suffered from sexual harassment now and. before, even a great number of males have experienced such sexual harassment. In case of female assistants, more than half of them suffered from sexual harassment suggesting us significant level of sexual harassment to female assistants. A depth of sexual harassment to assistants should be investigated in a further way by preparing for and establishing concrete preventive actions and researches, mostly suffered by males; In this respect, a preventive training of sexual harassment should be deemed to be provided to males. Thirdly, as a result of investigation of sex education and preventive action against sexual harassment in college, most of elementary, junior, junior high school hardly provide no or inefficient sexual harassment, and they responded that the campus needs its education. As a way to educate campus with sexual harassment efficiently, a special lecture or regular class might be designed for systematic education or sexual harassment through schools counseling room might be effective emphasizing upon role of the room according to opinions of responders. The college is required to install such offices or centers as can exclusively manage and take charge of sex education program operation, legal system of anti-sexual harassment, or personnel arrangement for such activities in school by reflecting such result into school for appropriate and efficient education of or counseling to sex.

This study was focused on discriminating the molecular sexes of red deer and elk by duplex polymerase chain reaction(PCR) using two primer sets. Sex differentiation of mammals is primarily dependent on the presence or absence of sex determining region Y(SRY) gene encoded on Y chromosome which plays a key role for male development. Zinc finger X-Y(ZFX-ZFY) gene, one of X-Y homology gene group was found on X- and Y- chromosomes, respectively. At first, the nucleotide sequences were characterized for the intron 9 flanking region of ZFX-ZFY genes. The intron 9 of ZFX and ZFY is 529-bp and 665-bp in length, respectively. A transposable element sequence similar to bovine SINE element Bov-tA was detected only in ZFY gene of Cervidae. Sexing analysis was conducted by duplex PCR assay for amplification of SRY and ZFX-ZFY genes. Two differentially amplified patterns were found: one for females has a common band amplified only from ZFX as a template, and another for males had three bands(a common ZFX and two male-specific ZFY and SRY). On the separate tests using each gene, the results was identical to those from duplex PCR assay. Moreover, the results from PCR assays provide also identical information to phenotypic investigation of individuals of red deer, elk as well as their hybridized progenies collected from two isolated farms. These results suggest that it may be a rapid and precise method for determining the sexes by duplex PCR amplification using Y-chromosome specific SRY and X- and Y- homologous ZFX-ZFY genes showing sexual dimorphism in red deer and elk without any other controls.

Three Korean native cattle (KNC) and seven exotic breeds (Chikso, Hanwoo, Jeju black, Holstein, Japanese black, Charolais, Angus, Hereford, Simmental, and Cross breed) were characterized by using five microsatellite (MS) markers (INRA30, TGLA325, UMN0803, UMN0905, and UMN0929) from the sex chromosome. Genetic diversity was evaluated across the 10 breeds by using the number of alleles per locus, allele frequency, heterozygosity, and polymorphism information content (PIC) to search for locus and/or breed specific alleles, allowing a rapid and cost-effective identification of cattle samples, avoiding mislabeling of commercial beef. It was divided into two main groups from STRUCTURE analysis, one corresponding to KNC and the other to exotic cattle breeds. These results also showed specific genetic differences between KNC and exotic breeds. Nei's standard genetic distance was calculated and used in the construction of a neighbor-joining tree. Results evidenced a correspondence between genetic distance, breeds' history, and their geographic origin, and a clear separation between KNC and exotic breeds. Overall, this study evidenced that DNA markers can discriminate between domestic and imported beef, contributing to the knowledge on cattle breeds' genetic diversity and relationships by using MS markers of the sex chromosome. These markers would be useful for inhibitory effect about false sales and for building an effective tracking system.

Objective : This empirical research is performed to recognize diagnostic concept, pattern identification, and clinical features of Hwa-byung. In other words, the aims of this research are to examine the differences of the diagnosis between Hwa-Byung and the other psychiatric disorders, and to find out pattern identification, and clinical characteristics of Hwa-Byung for prescriptions of this syndrome. Method : In the experiment, there were participated 30 patients who were met for our criterions according to HBDIS (Hwa-Byung Diagnostic interview Schedule). These patients were diagnosed as Axis1 according to criterions of DSM-IV with administering SCID-I. OMS-prime was utilized for finding out pattern identification of oriental medicine. Symptom Check List-90-Revision(SCL-90-R), Hemilton rating Scale for Depression(HRSD), Heart Rate Variability(HRV), and Digital Infrared Thermographic imaging(D.I.T.I.) were also utilized to discover clinical characteristics of Hwa-Byung Patients. Results : 1. Regarding Sex-ratio, male subjects were 3(10%), and female subjects are 27(90%). The age of subjects ranged from 22 year old to 75 $(51.87{\pm}11.04;\:Mean{\pm}SD)$ 2. In the results of diagnosis on the basis of DSM-IV, the 17(56.67%) patients were MOD (Major Depressive Disorder), the 5(16.67%) patients were USD (Undifferentiated Somatoform Disorder), the 4(13.33%) patients were Dysthymic Disorder, the 3(10%) patients were GAD (Generalized Anxiety Disorder), and the 1(3.33%) was Panic Disorder. Two of the patients who diagnosed as MOD were diagnosed as Panic Disorder too, and one of them was diagnosed as Pain Disorder too. 3. Regarding pattern identification, Hwa-Byung is positively correlated to deficiency of Heart(心). and then to stagnancy of Liver-Gall bladder. Hwa-Byung is correlated deficiency symptom-complex rather than excessiveness symptom-complex. That is also correlated positively to Pathological heat and fire. 4. In SCL90-R, the mean of PSDI was $(75.3{\pm}10.7;\:Mean{\pm}SD)$. The each mean of the other 11 factors was distributed between50-70. 5. The mean of HRSD was $(17.9{\pm}5.6;\:Mean{\pm}SD)$ in the entire subject's group. Then the group of MDD was $20.9{\pm}4.4$ and the group of USD was $12.0{\pm}4.8$ 6. In the results of HRV. the mean of TP is $972.4{\pm}1174(Mean{\pm}SD)$, this is lower than normal range 1000-200. The other factors were within normal range. Then, there were no significant differences between them (p<0.05). 7. The temperatures of each acupoint have significant differences between HNl(印堂) and PC6(內關), between CV17(顫中) and PC6(內關), between HN1(印堂) and CV8(神闕), between CV17(顫中) and CV8(神闕) in comparison with the average of body temperature in the use of D.I.T.I. (p<0.01) 8. In the analysis of correlation between SCL-90-R, HRSD, HRV. and D.I.T.I. there were no significant results. According to results that the correlation was analyzed with only the MDD group as subjects, there was negative correlation between RMSSD of HRV and HRSD, between LF of HRV and PDSIof SCL-90-R, and between LF/HF of HRV and ANX, PSY, and PDSI of SCL-90-R. Conclusion : In the observation of clinical features of 30 cases of Hwa-Byung patients by using diverse structured tests, there could make diverse diagnosis as depressive disorder, anxiety disorder, and Somatoform Disorder. Particularly. MDD was highly distributed. Considering oriental medicine's pattern identification of Hwa-Byung, this syndrome is related strongly to Heart, and there were demonstrated deficiency symptom-complex, and Pathological heat and fire. One of the limits of this study is lack of control subject's group, therefore, in the future study, it requires reexamination through a comparative research with these data to complete this study.

DNA typing is often used to determine identity from human remains. Recently, the molecular biological analysis of ancient deposits has become possible since methods for the recovery of DNA conserved in bones or teeth from archaeological remains have been developed. In the field of archaeology, one of the most promising approaches is to identify the individuals present in a mass burial site. We performed nuclear DNA typing and mitochondrial DNA sequencing analysis based on PCR from a Korea ancient human remain excavated from Sa-chon Nuk-island and civilian access controlline(CACL). A femur bone were collected and successfully subjected to DNA extraction, quantification, PCR amplification, and subsequently typed for several shot tandem repeat(STR)loci. 4 types of STR systems used in this study were CTT multiplex(CSF1PO, TPOX, TH01), FFv multiplex(F13A01, FESFPS, vWA), Silver STRⅢ multiplex(D16S539, D7S820, D13S317), and amelogenin for sex determination. This studies are primarily concerned with the extraction, amplification, and DNA typing of ancient human bone DNA samples. Also, it is suggestive of importance about closely relationship between both fields of archaeology and molecular biology.
