When a single source of multimedia contents is distributed to multiple reproduction devices, the audio and video contents require synchronous play for multi-channel stereo sound and lip-synchronization. The multimedia system in vehicle, especially, has researched to move to wireless environments from legacy wired environments. This paper proposes the advanced algorithm for providing synchronized services of real-time multimedia traffic in IEEE 802.11 WLANs [1]. For these, we implement the advanced IEEE 1588 Precision Time Protocol [2] and the environments for simulation. Also, we estimate and analysis performance of the algorithm, then we experiment and analysis after the porting of algorithm in wireless LAN devices (Linksys wrt-350n AP network device) to characterize timing synchronization accuracy.

The purpose of this study is to analyze and assess the family policy of the Lee administration and to suggest agendas for sustainable future family policy. Traditionally, families are a unique unit of production and reproduction of family members and social laborers. In addition, families are the social safety net help people survive in a society. Therefore, family policies play an important role in contemporary society. In this context, we review the literature related to family and social policy, and the contents of Ministry for Health, Welfare and Family Affairs, which is the main authority in Korea. The results are as follow: Firstly, the Lee administration ignored the data showing that family policy should be a unique policy, and not a sub-division of welfare policy. Secondly, there is no difference between the active welfare policy of the Lee administration and policies of past administrations. Finally, this study suggests that subjects of future oriented family policy should focus on co-developing programs for the individual, family, and society, to develop problem-prevention and family needs- ordered policy, and to make integrated family policy through laws and delivery systems such as Healthy Family Centers.

This study was conducted to measure the total protein, DNA, and RNA contents of corpus luteum(CL) in various stages of estrous cycle and pregnancy. CLs were collected from a local slaughterhouse and stages of the estrous cycle of CL were classified as CL1~2, days 1 to 10; CL3(with/without central cavity), days 11 to 17; CL4, days 18 to 20 by method of Ireland et. al(1980) and stages of the pregnancy of CL were classified as P1~3, months 11~3: P4~6, months 4~6; P7~9, months 7~9 of pregnancy. CL3 with/without central cavity(CC) was identified as described by Kastelic et. al.(1990)-CL with CC, more than 2mm in diameter; CL without CC, less than 2mm in diameter. In total protein content, CL3 with CC was significantly lower than P7~9(p<.05). The total DNA content was lower in CL3 with CC than CL3 without CC and CL4(p<.05). In protein : DNA ratio, CL3 with CC was significantly lower than CL4(p<.05), CL3 without CC was significantly lower than P7~9(p<.05), CL4 was significantly lower than CL3 with CC, P1~3 and P7~9(p<.05). No differences were observed in RNA content, protein:RNA ratio, RNA/DNA of CLs in stages of estrous cycle and pregnancy.

The purpose of present study was to analyze mineral contents in various tissues and investigate theirs relation with bone mineral density (BMD) in rats. Fifteen Sprague-Dawley rats were fed standard diet for 4 weeks. Body weight gain, feed intake, and feed efficiency ratio were 41.00 g/week, 171.15 g/week, and 0.24 respectively. Among 12 minerals in serum, Ca is the highest with 6.86 mg/dl. Serum Mg, Se, and Cu were 2.52 mg/dl, 0.23 mg/dl and 0.22 mg/dl respectively. Mg contents in liver, spleen, and kidney were $246.36\;{\mu}/g$, $105.01\;{\mu}/g$, and $273.38\;{\mu}/g$ respectively. Tibia contents of Ca, Mg, Zn, Fe and V were 194.91 mg/g, 23.10 mg/g, 0.60 mg/g, 0.35 mg/g and 0.14 mg/g respectively. BMDs of right tibia and spine were 122.04 mg/cm and $153.61\;mg/cm^2$. There were significantly positive correlations between tibia BMD and Se (p<0.05), tibia BMD and V (p<0.01), spinal BMD and V(p<0.05), respectively. It's expected that these results are used as a reference data in following study to elucidate physiological function of minerals.

The purpose of this study is to analyze modern fashion culture in the 20th century through changes in transmedia in order to better understand characteristics of fashion contents. The study also strived to identify the characteristics of remediation in modern fashion and media by exploring the cultural code, and use it to establish an integrated view. The subjects and the method of the study are as follows. First, the study analyzed the development of transmedia and fashion culture since the 20th century. Second, it identified the transitional characteristics of transmedia. Third, the study analyzed the characteristics of remediation in modern fashion culture by using the characteristics of mediation, which appeared with the transitional characteristics of transmedia. The study results are as follows. First, the types of remediation are 'borrowing,' 'Representation,' 'Expansion,' 'Refashion,' and 'Absorb.' In old and new media, each type can be aesthetically experienced in 'transparency,' opaqueness,' 'Hypermediacy,' and 'Immediacy.' Second, fashion culture can undergo a transformation from its original form to a second and a third iteration, and this process allows for possibility of an expansion of multiple plots and well-rounded character settings. This opens up the possibility for fashion consumer participation, and signifies a transition into an environment where expansion of time and space is possible. The third finding is the non-mediation of fashion objects. The mediating relationship between clothes and media is directly connected to the development of new media. The immersion of new media by fashion consumers has the characteristics of 'transparency'/'Non-mediation,' and the reinterpretation and reproduction of original fashion styles have the characteristics of 'opaqueness'/'Hyper-mediation.' Fourth, fashion culture has data variability. Through 'Borrowing,' 'Representation,' 'Expansion,' 'Remodeling,' and 'Absorption,' the cultural hierarchy of reproduced fashion forms a multi-layered integrated network. Mediation code, which repurposes fashion culture contents, also creates new media fashion through transmedia.

3D Audio Technologies include whole signal processing steps from acquisition to reproduction through encoding and transmitting technologies. However, there is a certain difference on adapted technologies according to audio presentation environments, because the presentation environment is the last step to provide 3D audio th listeners. In this paper, we describe variable 3D audio technologies to adapt variable audio presentation environments for consuming music contents.

MonA is a subunit of a guanine nucleotide exchange factor that is important for vacuole passing and autophagy processes in eukaryotes. In this study, we characterized the function of MonA, an orthologue of Saccharomyces cerevisiae Mon1, in the model fungus Aspergillus nidulans and a toxigenic fungus A. flavus. In A. nidulans, the absence of AnimonA led to decreased fungal growth, reduced asexual reproduction, and defective cleistothecia production. In addition, AnimonA deletion mutants exhibited decreased spore viability, had reduced trehalose contents in conidia, and were sensitive to thermal stress. In A. flavus, deletion of AflmonA caused decreased fungal growth and defective production of asexual spores and sclerotia structures. Moreover, the absence of monA affected vacuole morphology in both species. Taken together, these results indicate that MonA plays conserved roles in controlling fungal growth, development and vacuole morphology in A. nidulans and A. flavus.

Sperm competent for fertilization can become capacitated, bind to the zona pellucida (ZP) of an egg in a specific manner, and complete acrosomal exocytosis. Failure to carry out these functions results in infertility. Although the interactions between the ZP and the plasma mem-brane overlying the sperm acrosome have been considered important for sperm-egg recognition and signalling, recent results have prompted a reassessment of current paradigms concerning these interactions. In this review, we're going to discuss about the roles of the acrosomal matrix, the particulate component of the acrosomal contents, in fertilization. The general hypothesis is that acrosomal exocytosis leads to the exposure of acrosomal matrix proteins that become de-facto extracellular matrix (ECM) on the surface of the sperm head, and that the dynamic interactions of this newly-exposed sperm ECM with the egg ECM (the ZP) govern sperm-egg recognition and sperm penetration of the ZP Informations from these experiments may provide new ways to address the poor ZP binding of sperm from some human infertility patients and may offer new avenues for contraception through the disruption of purposeful sperm-ZP binding.

In the midst of the crisis in the publishing industry, the library was brought up as a facilitator. However, the premise is that libraries cannot revive the publishing industry simply as a catalyst for promoting reading culture. Rather, the publishing industry presented an expanded and regenerative system of publishing contents as a model for the promotion of publishing by embracing the active production and demand of readers based on libraries. In that process, we designed an independent publishing platform in the form of library/publishing collaboration (cooperation) and proposed a distribution and reproduction model.
