Objective: To explore potential relationships between sperm DNA integrity and both semen parameters and clinical outcomes. Methods: Semen analysis of 498 samples was performed according to the 2010 criteria of the World Health Organization. The sperm DNA fragmentation Index (DFI) of the semen samples was assessed using a neutral comet assay. Results: Sperm DFI showed a significant correlation with semen parameters, including the patient's age, sperm viability, motility, morphology, and number of leukocytes (p<0.05). The sperm DFI values for asthenozoospermic (15.2%), oligoteratozoospermic (18.3%), asthenoteratozoospermic (17.5%), and oligoasthenoteratozoospermic semen samples (21.3%) were significantly higher than that observed in normozoospermic semen samples (10.5%, p<0.05). A sperm DFI value of 14% was used as a threshold of sperm DFI in assessing whether DNA was highly damaged. In 114 IVF-ET cycles, the fertilization rate of the sperm DFI <14% group (70 cycles, 61.7%) was significantly higher than that observed for the ${\geq}14%$ group (44 cycles, 55.3%), but there was no difference in the other clinical outcomes between the two groups. In the ${\geq}14%$ group, the pregnancy rates of the ICSI cycles (40.0%) and half-ICSI (44.0%) were higher than conventional IVF cycles (30.7%), but the difference was not statistically significant. Conclusion: Along with the conventional semen analysis, the sperm DFI assessed using the comet assay was shown to improve the quality of the semen evaluation. To evaluate the precise effect of ICSI on pregnancy rates in the patients who demonstrate high sperm DFI values, further study is necessary.

Freud's' discovery of the unconscious' is a great revolution. Because of this, human beings were able to get the opportunity to look into their inner than honest. Lu Xun and Guo Mo Ruo a pair of realism and romanticism literature representative of Chinese modern literature writers. They then absorb the psychoanalytic theory o Freud along with other Western zeitgeist, introduce them widely inliterary theory and creative practice, which was again. Lu Xun was reflected in the human world of the unconscious Freud uncovered on the basis of strict realism literary spirit, Guo Mo Ruo is in accordance with the romantic literary time for the purpose of 'art for art' depicting a man's inner psychological well did. Although Freud spirit they claim to social and literary artistry of literature based on different yarns in the Acceptance of analytical theory, has the characteristics of a common sentiment analysis method to express and describe the unconscious human potential. 5.4 When Lu Xun and Guo Mo Ruo China Journalism writers, including Freud's psychoanalytic theory has embraced the Enlightenment and the old feudal society was a major contribution to want to read exactly what the human inner hearing. Chinese modern literature writers have to accept sometimes positive, sometimes accepting the psychoanalytic theory was intellectually sharp criticism, which could be a great instrument in time to the 5.4 Enlightenment and psychological fiction novel further development.

Today the number of economically independent women are increasing in Korea, they have a tendency to pay more attention to their appearance in their social life. Female university students show a high tendency of that kind, especially when they prepare for their job interviews. They purchase beauty products, visit beauty salons and skin care centers to improve their looks. Above all, their interest in nail art is amazingly increasing for maintaining their self-image. This study thus aims at surveying the relationship between college woman's life style and their interest in nail care, by analysing life styles of college women pursuing up-to-date style. The results show that an 'egoistic' type has a high interest in and a high frequency of using a nail care center, and 'egoistic' type's demand for the nail service is equal to or quite higher than 'appearance-oriented' type's. That means that the 'egoistic' type seems to pay much attention to how they look, because they think their neat appearance help to accomplish their ego.

The paper presents some new results illustrating some developments related to the concept of the Silk Road and subsequent methodological reflections. New laboratory results of scientific analyses of plants, minerals, and human remains in combination with more conventional methods of research contribute to a better understanding of the multidirectionality of exchanges in Pre- and Protohistory. Unsuspected long-distance transfers of items, especially of metals (tin) and biological materials (plants, pathogens, etc.) are discovered. Adding ancient DNA and petroglyphs to the vexed question of the Indo-European migrations across Eurasia complexifies the familiar linguistic, historical, and archaeological research landscape. Recent excavations show the impact of the adoption of artistic elements adapted from the Achaemenid arts, far in the steppe world, and up to China. Multidirectional (including North-South lanes) and multidisciplinary approaches leave space and hope for more rigorous scientific modelizations for the archaeology of Eurasia and the Silk Road.

For evaluating the suitability of human follicular fluid(HFF) as protein supplement in ART, this preliminary study was performed to examine the maturation promoting activity of HFF on mouse follicular oocytes in vitro. Mouse follicular oocytes were collected from ovaries of 21-28 day old ICR mice by puncturing the antral follicles with fine needle at 48 hours after PMSG injection. The oocytes were rinsed and cultured in modified Whittingham's $T_6$ medium containing purines or dbcAMP to maintain meiotic arrest, and different concentrations of HFF were added into the culture medium to examine the effect of HFF on releasing the oocytes from the suppressive influence of the meiotic inhibitors. As a control for HFF, the maturation promoting activity of human fetal cord serum(HFCS) was investigated and compared with the activity of HFF. While HFF was separated, by molecular weight(M.W), into high M.W. fraction(M.W>30,000) and low M.W. fraction(M.W<30,000) and the effects of the fractions on meiotic resumption were investigated in the presence of the meiotic inhibitors. Also hormone analysis was performed to compare the content of hormones in HFF with that in HFCS. Same concentrations of HFF and HFCS induced similar germinal vesicle break down(GVBD) rates of the oocytes meiotic arrested by purines(4mM hypoxanthine+0.75mM adenosine), but the extrusion rate of 1st polar body(PB) of the oocytes cultured in HFF(65.0%, P<0.05) was significantly higher than that(51.6%) in HFCS. While, in the presence of 200 M dbcAMP, the maturation promoting activity of HFF (GVBD: 70.5%, $p<10^{-6}$; 1st PB extrusion: 67.1%, $p<10^{-3}$) was significantly greater than that of HFCS(GVBD: 35.2%; 1st PB extrusion: 41.1%). The oocytes cultured in the fraction of HFF containing high M.W. components showed higher meiotic maturation rates than the oocytes cultured in the low M.W. fraction of HFF. Gonadotropins and $E_2$ were known to improve the completion of maturation changes, and the levels of these hormones were higher in HFF than in HFCS. Therefore, HFF was more effective than HFCS to use for promoting meiotic resumption of mouse oocytes in vitro.

Accurate detection, tracking and analysis of human movement using robots and other visual surveillance systems is still a challenge. Efforts are on to make the system robust against constraints such as variation in shape, size, pose and occlusion. Traditional methods of detection used the sliding window approach which involved scanning of various sizes of windows across an image. This paper concentrates on employing a state-of-the-art, hierarchical graph based method for segmentation. It has two stages: part level segmentation for color-consistent segments and object level segmentation for category-consistent regions. The tracking phase is achieved by employing SIFT keypoint descriptor based technique in a combined matching and tracking scheme with validation phase. Localization of human region in each frame is performed by keypoints by casting votes for the center of the human detected region. As it is difficult to avoid incorrect keypoints, a consensus-based framework is used to detect voting behavior. The designed methodology is tested on the video sequences having 3 to 4 persons.
