This study reflects the demand of content elements related to "Human Reproduction" in elementary school science curriculum, and verifies its effects by developing and applying sex education contents available to elementary science class. The developed contents is composed of three sections in reference to the contents guideline for teachers. The contents include anatomical knowledge related to human reproduction and reflect social and cultural context of sex ethics. The first section: "How was I born?", second section: "Amazing changes in my body" and third section: "Healthy body, healthy mind." In the result of analysis of changes in sex knowledge and attitude after applying the contents, it showed statistically significant differences between experimental and comparative class. Thus, the developed contents made positive influence on improvement in elementary students' knowledge and attitude of human reproduction. However, it showed little difference in the effects of sex education contents by the grade and gender. In conclusion, if the sex education contents developed through this study is actively applied, it is expected to provide the elementary students with knowledge of the anatomic difference between male and female, its social and cultural understanding and responsibility for sex ethics. In addition, it is considered to be used as effective education programs and materials in elementary school science curriculum.

In this study, we will examine that the social class is reproduced by the school curriculum from the viewpoint of cultural reproduction theory by Pierre Bourdieu. Specially, we will examine the sociality of the curriculum, the social control of cultural capital, and how these make class reproduction possible. In this study, social class is reproduced by the ideological orientation of curriculum. This means that the school curriculum has social character and is closely related to the cultural capital of the ruling class.

In this paper, we present a new class of interpolatory Hermite subdivision schemes of order 2 reproducing polynomials. Each member in this class, denoted by H_n for n ≥ 1, preserves polynomials of degree up to 4n + 1 admitting the approximation order of 4n + 2. Furthermore, it has free parameters which provide flexibility in designing curves/surfaces. H₁, the simplest and the most attractive scheme in this class, achieves C⁴ smoothness with the parameters in certain ranges, and its performance is demonstrated with numerical examples.

This study was conducted to analyze the diversity census of fecal microbiome in horses using meta-analysis of equine 16S rRNA gene sequences that are available in the Ribosomal Database Project (RDP; Release 11, Update 5). The search terms used were "horse feces (or faeces)" and "equine feces (or faeces)". A total of 842 sequences of equine feces origin were retrieved from the RDP database, where 744 sequences were assigned to 10 phyla placed within Domain Bacteria. Firmicutes (n = 391) and Bacteroidetes (n = 203) were the first and the second dominant phyla, respectively, followed by Verrucomicrobia (n = 58), Proteobacteria (n = 30) and Fibrobacteres (n = 24). Clostridia (n = 319) was the first dominant class placed within Bacteroidetes while Bacteroidia (n = 174) was the second dominant class placed within Bacteroidetes. The remaining 98 sequences were assigned to phylum Euryarchaeota placed within Domain Archaea, where 74 sequences were assigned to class Methanomicrobia. The current results will improve understanding of the diversity of fecal microbiome in horses and may be used to further analyze equine fecal microbiome in future studies.

This study covers the literature of theoretical backgrounds of royal ceremonial hair styles during Chosun Dynasty and demonstrates reproduction works of those hair styles reinterpreted in modern methods. As for the Chosun royal hair styles for ceremonies, there are Daesoo, Gudoomi, and Euyoumi for a royal queen, royal concubines, and royal lady attendants of Nae Myung Boo, department of general affairs of the royal court. These hair styles represents well that Chosun Dynasty kept its own class symbols through hair styles, which is valuable cultural resources of Korean traditional beauties. This study compares the new reproduction works of Daesoo, Gudoomi, and Euyoumi with existing literature pieces and related photos for clear understanding of these traditional hair styles. This study aims to activate the relevant researches into Korean traditonal hair styles, their reproduction methods and applicable usages in Modern Korea as well as useful data for them.

MiRNAs (microRNAs) are a class of small non-coding RNA molecules of ~21 nucleotides that down- regulate the expression of target genes at post-transcriptional level. In this study, we first accomplished a preliminary scan of miRNA expression using 65 and 90 day fetal pig skeletal muscle samples by microarray hybridization, and 34 miRNAs showed strong positive signals. Five of these miRNAs were selected for further investigation by real-time RT-PCR. The statistical analyses indicated that three miRNAs exhibited significant differential expression (p<0.05) during porcine muscle development from 65 to 90 days of gestation, e.g., miR-24 and miR-424 were down-regulated while miR-133a was up-regulated. Multi-tissue RT-PCR was performed to detect the expression patterns of the five miRNA precursors. The results showed that most of these precursor miRNAs were ubiquitously expressed in different porcine tissues.

This paper aims to study on attribute of interaction between user from cultural capital perspective of Bourdieu who expanded the concept of capital and presented class production and reproduction through 'World of Warcraft' play and analysis. The results of this study is that First, game ability showed properties of cultural capital that embodied, objectified, institutionalized. Second, the types of interaction by difference of cultural capital appeared that lurking, reciprocity, exclusion. This study identified game ability have attributes of cultural capital and that Due to the nature of the interaction for 'Disticion', individual actions are related to the process of accumulating power and contribute to class reproduction.

In this paper we have constructed a mathematical model of alcohol abuse which consists of four compartments corresponding to four population classes, namely, moderate and occasional drinkers, heavy drinkers, drinkers in treatment and temporarily recovered class. Basic reproduction number $R_0$ has been determined and sensitivity analysis of $R_0$ indicates that ${\beta}1$ (the transmission coefficient from moderate and occasional drinker to heavy drinker) is the most useful parameter for preventing drinking habit. Stability analysis of the model is made using the basic reproduction number. The model is locally asymptotically stable at disease free or problem free equilibrium (DFE) $E_0$ when $R_0&lt;1$. It is found that, when $R_0=1$, a backward bifurcation can occur and when $R_0&gt;1$, the endemic equilibrium $E^*$ becomes stable. Further analysis gives the global asymptotic stability of DFE under some conditions. Our important analytical findings are illustrated through computer simulation. Epidemiological implications of our analytical findings are addressed critically.
