In vitro developmental ability of early preimplantation monse embryos was shown to be depend on the embryonic stages, media and snpplements and their interaction(Experiment 1). The development of I-cell embryos were more promoted in the complex medinm(Ham's Fl0) than in the simple one(m-KRB), but that of 2-cell embryos showed the reverse effect. The bovine serum albumin(BSA) as a medium snpplement more promoted the development of I- and 2-cell embryos, compared with human fetal cord serum(HCS). On the other hand, the harmful effect of HCS was especially shown on the early cleavage in the embryonic development of the two stages. The effect of serum, in the respect of interaction between media and snpplements. was also more significantly appeared in m-KRB than Ham's Fl0. In the experiment 2, when the harmful effect of HCS was compared with that of fetal bovine serum(FBS), the former more promoted the development of l - and 2-cell embryos than the latter. The effect of HCS was more significantly shown in the development of I-cell than that of 2-cell embryos. Conclusively, as I- and 2-cell embryos were different in the requirements for the in vitro development. the optimal medium and supplement have to be selected for each embryonic stage. It is also respected to the better result if it take into consideration into the kinds of sera when serum is used for culture of early preimplantation embryos.

Objectives : This study was performed to investigate the effect of Needle-Embedding Therapy in early stage of intractable peripheral facial paralysis. Methods : 46 patients with severe peripheral facial paralysis were treated with oriental medicine therapy including Needle-Embedding Therapy in their early stage. We evaluated the effect of Needle-Embedding Therapy by House-Brackmann Grading system, decrease of subjective symptoms and satisfaction measurement. Results : After treatment, HB-Scale grade was significantly decreased(p-value<0.001). More than 50% of subjective symptoms were disappeared in 82.61% of patients. 80.48% of the patients was satisfied with the Needle-Embedding Therapy. Conclusion : Needle-Embedding Therapy could be effective to improve symptoms of severe peripheral facial paralysis in early stage. Further studies will be required to identify the beneficial effect of Needle-Embedding Therapy in early stage of peripheral facial paralysis.

본 연구의 목적은 예비유아교사들의 교직선택동기, 진로적응력, 자기주도학습 간의 관계는 어떠한지 알아보며, 예비유아교사의 교직선택동기가 진로적응력과의 관계에서 자기주도학습을 매개로 하여 미치는 영향을 분석하는 것이다. 본 연구에서는 부산광역시 소재 예비유아교사 271명을 대상으로 교직선택동기, 진로적응력, 자기주도학습는 어떠한지를 알아보기 위해 기술통계를 실시하였고, 각 변인간의 상관을 알아보기 위해 Pearson의 적률상관계수를 구하였고, 중다회귀분석과 매개효과의 유의성을 검증하기 위하여 Sobel Test를 실시하였다. 그 결과 첫째, 예비유아교사의 교직선택동기, 자기주도학습, 진로적응력의 인식에서는 진로적응력, 자기주도학습, 교직선택동기 순으로 높게 나왔다. 둘째, 교직선택동기가 높아질수록 자기주도학습과 진로적응력이 높아지고, 자기주도학습이 높아질수록 진로적응력이 높아지는 정적 상관이 나타났다. 셋째, 예비유아교사의 자기주도학습은 교직선택동기와 진로적응력을 부분매개하는 것으로 나타났다. 본 연구는 질 높은 유아교사교육을 실천하는데 다양한 관점을 모색하고 유아교사 양성기관의 교사교육 프로그램 개발을 위한 기초자료를 제공하였다는 점에서 의의가 있다.

The purpose of this study is to examine factors affecting the diffusion and the intention to use, and how these factors differ among adopter categories. A survey was done to analyze the diffusion of smart-phone, the most popular and innovative product nowdays. We collected 197 survey questionnaires from smart-phone user and analyzed the data using SPSS 18.0 and Smart PLS 2.0. PLS (Partial Least Square) analysis was implemented before multiple group-innovator, early adopter, eraly majority- analysis which is categoriezed by Innovation Diffusion Model of Rogers (1995). The results show that firstly, in innovator group (n=63), the functional and the safety value have significantly positive effect on user satisfaction. In addition, we found that user satisfaction and the brand loyalty are significatly associated with the intention of use. Secondly, in early adopter group (n = 67), the design value has significantly positive effect on user satisfaction and it has significantly positive effect on brand loyalty. Finally, in early majority group (n = 67), the design value has significantly positive effect on the user satisfaction and it has stronger effect on the intention of use and brand loyalty. We conclude this paper with the implication of this study to both academia, business practice, and policy making.

Creep is a major parameter to represent long-term behavior of concrete structures concerning serviceability and durability. The effect of creep is recently taking account into crack resistance analysis of early-age concrete concerning durability evaluation. Since existing creep prediction models were proposed to predict creep for hardened concrete, most of them cannot consider effectively the information on microstructure formation and hydration developed in the early-age concrete. In this study, creep tests for early-age concrete made of the type I cement and the type V cement are carried out respectively and creep prediction models are evaluated for the prediction of creep behavior in early-age concrete. A creep prediction model is modified for the prediction of creep in early-age concrete and also verified by comparing prediction results with results of creep tests on early-age concrete.

Severe sepsis and septic shock is a life-threatening disease. It is combined with multi-organ failure. In the past decade, early goal directed therapy has been proposed as an effective treatment strategy for better outcome. Recent epidemiologic studies showed that the outcome of sepsis has been improved with the introduction of early goal directed therapy. However, it is unclear which elements of early goal directed therapy contributed to the better outcome. Recent prospective and randomized trials suggested that some elements of early goal directed therapy did not have any effect on the outcome benefit. In this paper, recent articles about early goal directed therapy will be reviewed and the effectiveness of individual elements of early goal directed therapy will be discussed.

Purpose: The purpose of this study was to identify the influence of early menarche on sexual experience among high school girls in South Korea. Methods: The study sample was comprised of 16,286 high school girls. Using statistics from the 11th (2015) Korea Youth Risk Behavior Web-based Survey, hierarchical logistic regression analysis was conducted. Results: Among the girls, 5.8% reported early menarche. Early menarche was associated with sexual experience (Odds Ratio (OR), 5.27; 95% Confidence Interval (CI), 4.11-6.77). Controlled for sociodemographic, emotional and health behavior characteristics, early menarche was associated with sexual experience (OR, 3.98; 95% CI, 3.04-5.21). Conclusion: The results indicate that early menarche predicts an increase in sexual experience among female adolescents. Therefore, health education programs and health policy for interventions to improve sexual health are required for girls who are expected to experience early menarche.
