The kitsch was emerged from the people's cultural desire in the conditions of the various duplicating technology, the capital economy system, and the civil revolution in the western modern mass society. But it is underestimated constantly because of the conspicious consumption and the aesthetic inadequacy. Even though some kitsches are elevated to the 'kitsch arts' in the historical description of the modern arts, still the most of kitsches are remained as 'just kitsches' and excluded from the aesthetic research according to the double standard. In this essay, I research for whether anti-kitsch theory is convincing theoretically and practically. Anti-kitsch theory criticizes the kitsch on the basis of the modernist aesthetics, in which the 'fine art' provokes the aesthetic pleasure in the disinterested contemplation. But kitsch purposes for the sensual gratification and the sentimentality. So the anti-kitish theorists conclude that the kitsch is the bad taste. In critically analyzing the argumentation of Greenberg's. Kaplan's and $C{\tilde{a}}linescu^{\prime}s$, I refute the privileged prejudice of the ideal critic. They don't justify the criteria of the classification of 'art'/ 'kitsch'. They supplement the economical and the political grounds for the evaluative theory of the kitsch. But the argumentation of the kitsch is consumed conspicuously and results in the unlettered masses is not sufficient. People produce and enjoy the kitsches in the various ways. People envelope the genres, styles and media of the kitsches and they try to suggest the new horizon of the popular aesthetics. So anti-kitsch theories cannot be accepted because they adhere to the elitism and formalism. The exclusion of the kitsch is the derogation for people's taste. Also they didn't reflect the contemporary cultural practice and the aesthetic needs in the system of post-art. The alternative aesthetics of the kitsch is the topic of my next essay.

This experiment was conducted to analyse the effects of flavone supplementation on the preimplantation development of in-vitro produced porcine embryos. During in-vitro development, immature oocytes and early embryos were exposed to different concentrations of flavone (0, $1{\mu}M$, $25{\mu}M$, $50{\mu}M$, and $100{\mu}M$ respectively). Results showed that $100{\mu}M$ of flavone significantly reduced the intracellular ROS levels of oocytes accompanied with a significant rise in GSH level. In parthenogenesis, no significant change was observed in the cleavage rates whether flavone was supplemented in IVM or IVC media. In IVM supplemented group, the blastocyst development rate was significantly enhanced by $1{\mu}M$ concentration than other groups (51.5% vs. 41.3%, 44.0%, 36.3%, 31.7%; P<0.05) respectively. However, in IVC group $1{\mu}M$ concentration significantly improved the blastocysts production than $50{\mu}M$ and control groups (50.0% vs. 40.5%, 38.0%; P<0.05) respectively. Following nuclear transfer, the cleavage rate of IVM group was significantly more in $1{\mu}M$ than $50{\mu}M$ and $100{\mu}M$ groups (92.9% vs. 89.7%, 87.8%; P<0.05), followed by similar pattern of cloned blastocysts production being significantly higher in $1{\mu}M$ group than $50{\mu}M$, $100{\mu}M$ and control groups (16.8% vs. 9.0%, 7.1%, 12.8%; P<0.05) respectively. In IVC group, $1{\mu}M$ concentration resulted in significantly higher cleavage rate than $25{\mu}M$ and $50{\mu}M$ groups (91.7% vs. 87.8%, 88.8%; P<0.05) respectively. However, the blastocysts production was significantly higher in $100{\mu}M$ group than others (26.2% vs. 13.6%, 14.0%, 18.2%; P<0.05) respectively. The optimal concentrations of flavone significantly enhanced the percentages of ICM:TE than control group (43.8% vs. 37.6%; P<0.05) accompanied with significantly higher expression levels of reprogramming related genes. In conclusion, the optimal concentrations of $1{\mu}M$ during IVM and $100{\mu}M$ during IVC can significantly improve the production of porcine in-vitro embryos.

Non-Contact society has arrived due to social distinctions by COVID 19 pandemic. The arrival of the era of non-contact is having a profound impact on educational activities as well as on our social and economic lives. In response to the pandemic situation universities and all other educational institutions have implemented non-contact online classes. In particular arts physical educations and other practical classes are experiencing many difficulties due to the limited environment caused by social distancing from COVID 19 pandemic. Vocal classes are undergoing a transition mainly from 1:1 individual face-to-face lessons or group teaching methods to the non-contact era of online teaching or lesson methods. It is necessary to look at the direction of non-face-to-face practical classes in preparation for accelerated educational innovation. Edu-tech, which innovates technology in the wake of the age of non-contact after COVID 19 pandemic is expected to begin in earnest at school sites in Korea which have remained in the traditional way of education. The purpose of this study is to effectively non-contact vocal instructional methods by cogitating the current state of higher practical education and vocal classes in Korea. In addition, This study conducted two components of satisfied instructions such as 'Priorlearning of monitoring of recorded singing', and 'Immediate analyzing of various vocal contents and supplementary lessons of music theory' with a research on the peos and cons of non-face-to-face vocal class. Over a period of time, The effective non-contact of vocal instructional methods is in need to supplement non-face-to-face vocal class problems and further research and system construction with non-face-to-face vocal class's pros and cons to construct high-quality lecture contents is warranted.

As altmetrics has received a lot of attention as an muti-dimensional impact assessment tool, it is necessary to verify whether it can supplement the citation-based research performance evaluation system. This study analyzed and compared the effects of each altmetrics sources on citation by sampling 1,600 high-cited papers published in the last 10 years (Sample A) and non-year-limited papers (Sample B) indexed in Scopus. In addition, it was analyzed whether the OA of the paper had a moderating effect on the numbers of cited-by, and the difference according to the samples was verified. As a result of the analysis, only the number of Mendeley bookmark readers was analyzed to have a positive (+) effect on the numbers of cited-by, and OA status had a significant moderating effect in both groups. However, in sample A, OA showed a reinforcing effect on cited-by, whereas Sample B showed a weakening effect, showing a difference. On the other hand, social mention such as media reports do not have a significant effect on the cited-by regardless of OA conditions, but they can be used to understand the social impact of non-academic mass readers.

Endocrine disrupting chemiclas (EDCs) such as bisphenol A (BPA) and nonylphenol (NP) have estrogenic activity and can alter reproduction in fish. In the present study, the effects of BPA and NP on in vitro steroid production from oocytes of maturation stage (oocyte diameter$\fallingdotseq$1.88 mm) from the greenling (Hexagrammos agrammus) were evaluated. Oocytes were incubated with different concentrations of BPA and NP (0.1, 1, 10, 100 and 1,000 ng/$m{\ell}$) in the presence or absence of 50 IU human chorionic gonadotropin (HCG) for 48 hours. After incubation, levels of $17{\alpha},\;20{\beta}$-dihydroxy-4-pregnen-3-one ($17{\alpha}20{\beta}OHP$), estradiol-$17{\beta}(E_2)$ and testosterone (T) from incubated media were quantified by radioimmunoassay (RIA). In BPA treatment, 100 ng/$m{\ell}$ of BPA stimulated $E_2$ production regardless HCG supplement. Every concentration of BPA inhibited T production without HCG although 0.1 ng/$m{\ell}$ of BPA stimulated T production with HCG. In NP treatment, 10 ng/$m{\ell}$ of NP stimulated $17{\alpha}20{\beta}OHP$ and T production without HCG. 1 ng/$m{\ell}$ of NP inhibited $E_2$ production. Taken toghther, these results suggest that BPA might have weak estrogen-agonistic effect and NP has estrogenantagonistic effect at final oocyte maturation stage of H. agrammus.

This study was carried out to improve of effective culture system on development of IVM/IVF/IVC bovine embryos. The cumulus-oocyte-complexes (COCs) collected from Korean cattle ovaries harvested at a local abattoir were matured in 50 ${mu}ell$ of TCM199 supplemented with 10% fetal bovine serum (FBS) and hormones (35 $\mu\textrm{g}$/$m\ell$ FSH, 10 $\mu\textrm{g}$/$m\ell$ LH, 1$\mu\textrm{g}$/$m\ell$ estradiol 17 $\beta$ under paraffin oil at 39$^{\circ}C$ in a humidified atmosphere of 5% $CO_2$in air. At 24 hrs after culture, matured oocytes were fertilized in vitro for 22~24 hrs with motile semen in which obtained by centrifugation of a frozen thawed semen on Percoll-density gradients (45% vs. 90%) at 500 g for 20 min. The presumptive zygotes were divided into three experimental groups. Single egg (Group 1), 25 (Group 2) or 50 eggs (Group 3) were cultured on cumulus cell in 50 ${mu}ell$ TCM199 supplement with 10% FBS for 6~9 days after fertilization. In vitro developmental rates into the blastocysts in the groups 2 and 3 were significantly (P＜0.05) higher than those of group 1 (37,27 vs. 6%, respectively). Cell number of blastocysts obtained in groups 2 and 3 at day 8 were significantly (P${mu}ell$) resulted in higher developmental competence and cell number of bovine blastocysts produced in vitro than those the culture of single embryos with cumulus cells.

Some factors effecting on mycelial growth and cultural substrates using pine sawdust were investigated to develop an artificial cultivation technique. The optimal temperature and media pH for the mycelial growth were at $25^{\circ}C$ and 4.0, respectively. The mycelial growth was not different among three isolates tested. Among them ASI 19003 isolate showed the highest mycelial density and fruitbody yield. Among supplements added into pine sawdust, wheat bran was the best and its appropriate percentage was 20 for the mycelial growth. The mycelial densities were uprisen according to the amounts of the supplement. The highest yield, 107g/bottle of the sporophores of the mushroom was obtained from the substrates supplemented by 30% of wheat bran, but no fruitbody was formed on non supplemented one. Optimal moisture contents of the substrates was different for the mycelial growth, pinheading and fruitbody yields. Sixty five, 60 and 75% of moisture contents of the substrates were optimal for the mycelial growth, pinheading and fruitbody yields, respectively.

This study was conducted to examine the therapeutic compliance and its related factors in rural women with osteoporosis. A questionnaire survey was performed from April to May in 2000 for 140 osteoporotic patients who were diagnosed from April to June in 1999 through community health program. The study employed the health belief model for predicting and explaining sick role behavior. The analysis techniques employed included contingency table analysis and path analysis using LISREL. The major results of this study were as follows: Of the subjects, 12.1% were continuously complaint, 53.6% were intermittently compliant, and 34.3% were non- compliant to calcium supplement therapy. As the result of path analysis, the therapeutic compliance was significantly higher(${\mid}T{\mid}$ >2.0) as patients had higher perceived severity of disease, lower perceived barriers of treatment, and when patients thought their disease status as severe. As the patients had higher educational level, more experience of mass media contact or health education about osteoporosis, and when family had more concern for patient treatment, they had higher perceived susceptibility of complication(bone fracture)${\mid}T{\mid}$ >2.0). The patients had higher perceived severity(${\mid}T{\mid}$ >2.0) as they had more educational level, more advice for treatment from their doctors, and when family had more concern for their treatment. As the patients had more advice for treatment from their doctors and when family had more concern for their treatment, they had higher perceived benefit of treatment and lower perceived barriers to treatment(${\mid}T{\mid}$ >2.0). In order to improve the therapeutic compliance in rural osteoporotic women, it would be necessary that the patient should recognize their disease severity properly. And the perceived barriers should be removed through supportive environments for osteoporosis treatment such as doctor 's more advice and family 's more concern for treatment. In addition, effective and continuous management system for osteoporotic patients should be established.

Various functional foods, marketing health and functional effects, have been distributed in the market. These products, being in forms of foods, tablets, and capsules, are likely to be mistaken as drugs. In addition, non-experts may sell these as foods, or use these for therapy. Efforts for creating health food regulations or building regulatory system for improving the current status of functional foods have been made, but these have not been communicated to consumers yet. As a result, problems of circulating functional foods for therapy or adding illegal medical to such products have persisted, which has become worse by internet media. The cause of this problem can be categorized into (1) product itself and (2) its use, but in either case, one possible cause is lack of communications with consumers. Potential problems that can be caused by functional foods include illegal substances, hazardous substances, allergic reactions, considerations when administered to patients, drug interactions, ingredients with purity or concentrations too low to be detected, products with metabolic activations, health risks from over- or under-dose of vitamin and minerals, and products with alkaloids. (Journal of Health Science, 56, Supplement (2010)). The reason why side effects related to functional foods have been increasing is that under-qualified functional food companies are exaggerating the functionality for marketing purposes. KFDA has been informing consumers, through its web pages, to address the above mentioned issues related to functional foods, but there still is room for improvement, to promote proper use of functional foods and avoid drug interactions. Specifically, to address these issues, institutionalizing to collect information on approved products and their side effects, settling reevaluation systems, and standardizing preclinical tests and clinical tests are becoming urgent. Also to provide crucial information, unified database systems, seamlessly aggregating heterogeneous data in different domains, with user interfaces enabling effective one-stop search, are crucial.
