  • As modern society advances, women's self-consciousness and attitudes toward beautiful appearances have changed. Amid this trend, the young and slim body of adolescent girls expressed in contemporary fashion incites fantasy on continuing youth among women. In modern society, women's youth is frequently regarded as a subject of consumption and a sex product in the mass media. In this regard, the study is focused on examining desire and psychology of worshipping women's youth and beauty in connection with flapper fashion in the 1920s. In the process, the study took a look at the social and cultural background of flapper fashion and conducted an analysis on formative characteristics and aesthetic sense of flapper fashion as follows: First, the formative characteristics include a short skirt that expresses straight lined shape and the beauty of exposure, lighter clothing, thick make-up, short hair style and black or vivid colors, and they lead to exceptional and innovative aesthetic sense in flapper fashion. Flapper fashion style is focused on completely denying outdated fashion worn by women in the age right before. Second, pursuit of mature, graceful and classical beauty that had continued in previous ages has gone through complete changes in the flapper era in the name of pursuit of youth, and the flapper fashion expresses sensual image through the exposure of slim arms and legs of a young girl. In the formative characteristics, aesthetic sense of youth and sensuality inherent in the flapper fashion was generated. Third, women's free-spirited lifestyle at that time and 'aesthetic sense of freedom and amusement that reflected the speed of machine civilization could be found in the flapper fashion. Material and decoration of the flapper fashion pertained to clothing that enabled a free expression through rapid movements. Aesthetic sense of the flapper fashion generated in the process could be defined as women's internal determination to express individual and free-spirited ideas through the use of fashion when tradition and order of the old age were torn down. And this aesthetic sense is continuously affecting modern fashion design.

  • Despite great commercial interest, relatively little has been described about molecular mechanism of bivalve reproduction. We investigated genes involved in ovarian maturation of the Yesso scallop, Patinopecten yessoensis. GSI index and histological analysis revealed that maturation of ovary begin in February and spawning period is from April to June which is similar to the previous study in the East Sea. As result of combination analysis of differential display RTPCR (DDRT-PCR) and histological examination, vitellogenin (Vg), ferritin (Ft) and ADT/ATP carrier protein (ACC) were identified as differently expressed genes in maturating ovary. Endpoint RT-PCR results showed that Vg is ovary-specific genes whereas Ft and ACC are expressed ubiquitously suggesting that Vg can be good molecular markers for ovarian development and sex determination in bivalves. Quantitative PCR results revealed that Vg were expressed highest during growth stage and appears to play a major role in oocyte maturation. On the contrary, expression of Ft was highest after spawning stage, which suggests that up-regulation may be involved in spawning and inactive stages in which the scallops recover from spawning. In addition, high level of the mitochondrial gene, ACC, may play a role in energy metabolism in maturating oocytes. Isolation and molecular studies of these key genes will expand our knowledge of the physiological changes from various exogenous factors including temperature, salinity, pH, even or numerous endocrine disrupting chemicals (EDCs) during reproductive cycle. In addition, further study of these genes implicates various industrial applications including the stable seed production, increased food quality, or economic aquaculture system.

  • This study was aimed to determine influenza vaccination coverage in 2004 in Koreans and investigate the factors associated with vaccination. Documentation of vaccination status and baseline data was conducted by a survey using questionnaire sheets. Baseline data and vaccination status were documented on 1465 people out of whom 60.1% received the influenza vaccine. Forty-seven percent of the responders were male; 4% were aged 1-12, 32% were aged 13-39, 32% were aged 40-64 and 32% were aged 65 or older. Twenty-three percent reported a chronic illness, increasing their risk for complications from influenza. Predictors of influenza vaccination were: older age (OR=11.7, 95% CI 5.1-26.8), the presence of chronic illness (OR=2.3, 95% CI 1.1-4.7), previous vaccination (OR=1.8, 95% CI 1.1-2.8), belief that influenza vaccine is effective in preventing influenza (OR=2.5, 95% CI 1.1-5.7) and education level (OR=1.7, 95% CI 1.0-2.7). Immunization rates were much higher in those who will take immunization again (OR=10.4, 95% CI 5.5-19.6). Factors affecting the decision on immunization were self-determination (43.6%), public relations (24.1%), recommendation from family members or friends (22.4%) and consulting with health professionals (5.8%). The main reason not to take influenza vaccine was the thought that they are healthy (50.1%). Overall, influenza vaccine coverage was high in those aged 65 or older. Immunization against influenza was influenced more by existing medical problem and belief about the vaccine's effectiveness, rather than sex or residence.

  • In this paper, simulation was used to determine accuracies of genomic breeding values for polygenic traits associated with many thousands of markers obtained from high density genome scans. The statistical approach was based upon stochastically simulating a pedigree with a specified base population and a specified set of population parameters including the effective and noneffective marker distances and generation time. For this population, marker and quantitative trait locus (QTL) genotypes were generated using either a single linkage group or multiple linkage group model. Single nucleotide polymorphism (SNP) was simulated for an entire bovine genome (except for the sex chromosome, n = 29) including linkage and recombination. Individuals drawn from the simulated population with specified marker and QTL genotypes were randomly mated to establish appropriate levels of linkage disequilibrium for ten generations. Phenotype and genomic SNP data sets were obtained from individuals starting after two generations. Genetic prediction was accomplished by statistically modeling the genomic relationship matrix and standard BLUP methods. The effect of the number of linkage groups was also investigated to determine its influence on the accuracy of breeding values for genomic selection. When using high density scan data (0.08 cM marker distance), accuracies of breeding values on juveniles were obtained of 0.60 and 0.82, for a low heritable trait (0.10) and high heritable trait (0.50), respectively, in the single linkage group model. Estimates of 0.38 and 0.60 were obtained for the same cases in the multiple linkage group models. Unexpectedly, use of BLUP regression methods across many chromosomes was found to give rise to reduced accuracy in breeding value determination. The reasons for this remain a target for further research, but the role of Mendelian sampling may play a fundamental role in producing this effect.

  • Estimated liveweights, carcass characteristics, the proximate composition and amino-acid composition of the whole rib cut of the 10th/12th thoracic vertebrae have been determined for Jiulong-yak. The animal grows rapidly up to puberty at 2-3 years of age. At those ages, females reached 143.0$\pm$34.7 kg and 184.0$\pm$30.8 kg (SD) respectively, which was 60 to 80% of their mature weight at 6 to 7 yr old, then the rate of growth significantly slowed down. Males continued to rapidly increase body weight until an older age possibly due to the selection procedures. Animals included 20 males aged from 2.5 to 6.5 yr, seven females aged of 4.5 yr and 11 steers aged of 4.5-5.5 yr were slaughtered for carcass determination and chemical analysis of meat samples. Dressing-out percentage and ribeye area ranged from 48.53-55.04% and 48.02-68.56 $cm^2$ respectively, both of which differed by age and sex. Yak meat is scarlet in color and intramuscular marbling is poor. The 10th/12th rib-cut contained 24.99-31.93% dry matter; 19.98-22.58% protein; 2.52-10.86% fat and 0.93-1.00% ash. Meat from females and steers contained a higher percentage of fat than those from bulls. The pH of M. Longissimus dorsi measured at 24 h post-mortem ranged from 5.84-6.11. Amino acid composition was similar to that for other red meat, except for a lower content of methionine (1.26 g/100 g meat). The results indicated that yak meat can make a valuable contribution to the diets for the highlanders.

  • Purpose: Detection and determination of tendon injury in the finger or hand is not easy. Therefore, we aimed to study and evaluate the accuracy and the effectiveness of ultrasonography for the diagnosis of finger tendon injury. Methods: In this study, we enrolled patients, regardless of age and sex, with lacerations on their fingers. Patients with invisible wounds were excluded. We evaluated the accuracy and the effectiveness of ultrasonography and compared the results obtained from ultrasonography and with those obtained by visual observation of the injuries. Results: The sensitivity, the specificity and the accuracy of ultrasonography were found to be 66.7%, 100% and 91.3%, respectively (p<0.001) while those of physical examination were 71.4%, 98.3% and 91.3%, respectively. Small differences were observed between the sensitivities and specificities of the two examinations; however, the accuracies were the same (p<0.001). The area under the receiver operating characteristic (ROC) curve, which was used for diagnosis of tendon rupture using ultrasonography, was found to be 0.985 (95% confidence interval CI: 0.929-0.999),while that of physical examination was 0.938 (95% CI: 0.861-0.980). Conclusion: Ultrasonography can be used an effective diagnostic tool for patients with finger tendon injury.

  • This study aims to investigate on the perception types of online games and their characteristics. In Study 1, perceptions of online games were researched through Q methodology. From the results, the perceptions of online games are classified into four types: 'Online Game is an Obstacle of Study'; 'Online Game is Just a Game'; 'Online Game is a Stain in Life'; 'Online Game is Vaguely Bad'. Each perception type has different characteristics in terms of perception of harmfulness of games, determination of the core of game problems, and perception of a parent-child relationship. In Study 2, the distribution and characteristics of each perception type were researched through an online survey. The results show differences in an attitude to online game using features and regulations as well as in demographic parameters such as sex and age. This study holds its significance in identifying the differences between perception types of online game and providing a basic study for policy making of healthy game culture.

  • SOX9과 SRY 유전자는 척추동물에서 남성고환의 형성을 유도하는 요소로 알려졌다. SOX9 유전자는 SRY related HMG box gene중 하나로 유전질환의 XY성전환 및 성을 결정하는 데에 관여하며 성결정시기에 그 양에 따른 성전환 발생등 연구가 진행되고 있다. 그러나 이 유전자가 성별판정에 유용할 지는 확실치 않다. 반면 SRY 유전자는 포유동물에서의 배형성시기 고환형성을 결정하는 Y염색체 유전자로 남성에만 존재하고 여성에는 존재 않는다. 현재까지 이을 이용하여 법의학적 검체에서 남성판별에 유용하게 사용되고 있다. 본 실험에서는 X, Y와 같은 성염색체가 아닌 상동염색체상에 있으면서 SRY 유전자와 더불어 남성고환을 결정하는 또다른 요소로서의 기능을 가진 SOX9 유전자를 치아에서 검출하여 법의학적 성별판정에 유용할 수 있는지 알아보고자 본 연구를 수행하였다. 남녀각각 5개의 치아에서 치수와 상아질을 분리한 후 DNA를 추출하여 SOX9과 SRY 유전자의 특이적인 시발체를 제작하고 중합효소연쇄반응을 시행하여 증폭하고 전기영동을 시행하였다. 그 결과 SOX9 유전자는 남녀모두에서 유전자가 검출되었고, SOX9 유전자산물과 SRY 유전자를 혼합하여 사용시 남자에서만 유전자가 검출되었다. 이는 법의치과학적 성별판정에 있어 SOX9 유전자는 사람의 치아에서는 남녀 모두 존재하며 남녀 구별을 위한 성별판정에는 이용할 수 없으며 SRY 유전자와 함께 적용시 남성 특이적 SRY 유전자 검사중 발생할 수 있는 가성 음성 반응여부를 확인하는 데 유용할 것으로 사료된다.

  • 초기배의 성판정은 대상가축의 성을 선발하는 수단으로써 뿐만아니라 인간의 유전적 질병의 조기진단법으로서 매우 가치가 크다. 체외수정 소 초기배의 성을 결정하기 위해 PCR과 PRINS를 이용하였으며 성판정에 이용된 8 세포${\sim)$배반포기 초기배는 체외수정후 난관상피세포와의 공배양에 의해 생산되었다. 초기배 의 DNA는 $200{\mu}g/ml$ proteinase K가 함유된 PCR lysis buffer에 하나의 초기배를 부유한 후 $50^{\circ}C$에서 1시간동안 처리하여 준비하였다. 중기 염색체 spreads는 초기배를 nocodazole로 처리한 후 air-drying 방법을 이용하여 준비하였다. 가능한 false positive signals을 배제하기 위해 소특이 및 Y 염색체 특이 primers를 이용하여 PCR을 수행한 결과, 웅성 초기배에서는 두 개의 증폭산물 (소특이 및 Y 염색체 특이)이 합성된 반면 자성 초기배에서는 하나의 증폭산물만 합성되었다. 한편 중기염색체상의 Y 염색체를 동정하기 위해 FISH와 PRINS를 수행한 결과, FISH에서보다 PRINS에서 더 강한 Y 염색체 특이 형광 signals이 탐지되었다. 이러한 결과는 PCR에 의한 체외생산 소 초기배의 신속정확하고 효율적인 성판정이 가능함을 보여주었다. 또한 PRINS를 통해 PCR 에 이용된 Y 특이 probe의 신뢰성이 염색체 수준에서 확인되었다.
