The purpose of this study is to investigate the effect of flipped learning-based health assessment education on academic achievement of nursing students. The subjects of the study included nursing students attending second year at university. For 10 weeks, the experimental group was exposed to flipped learning-based classes, and the control group was provided with traditional lectures and team learning-based classes. In the intermediate evaluation, the knowledge and performance scores of the experimental group and the control group were statistically significant, and in the final evaluation, the knowledge and performance scores of the experimental group and the control group were statistically significant. The integrated knowledge score, evaluated three times after the end of the training, was higher in the experimental group than in the control group. These results suggest that flipped learning is an effective teaching and learning method for improving knowledge and performance of nursing students. Therefore, the application of flipped learning in various nursing education areas should be studied.

This study examines characteristics of sports movies between Korea and the U.S. Especially, this paper focuses on three different characteristics including structural, internal characteristics and performance of sports movies. The major results are as follows: firstly, there were similarities between two countries in terms of opening year, genre, classification but movie subjects. More specifically, movie opening years were not related to global sports events. In addition, most sports movies were mainly produced by human genre and all age movie classification. However, in terms of sports subjects, although Korean movies were constructed by baseball game, the U.S. movies were based on football game. Secondly, there were also similarities between both sports movies in terms of external characteristics such as gender difference of hero or heroine, internal story structure and their story sources. Most of sports movies have used real stories as movie story. Finally, although many of the U.S. sports movies recorded the high degree of expenditures, three movies recorded the high degree of movie consumption.

Objectives : Early detection and proper management of distress are known to be important for efficient care in cancer patients. The aim of this study was to investigate the prevalence of distress and to evaluate its influence on quality of life in subjects with breast cancer. Methods : A total of 95 patients were recruited from a breast cancer patient community of a general hospital in Seoul. The Hospital Anxiety and Depression Scale(HADS), the Insomnia Severity Index(ISI), the Impact of Event Scale-Revised(IES-R) and the Functional Assessment of Cancer Therapy-Breast(FACT-B) were measured. Results : The prevalence of anxiety, depression, insomnia and posttraumatic stress disorder symptom among breast cancer patients was 26.3%, 26.3%, 13.7%, 24.3%, respectively. Nearly half(47.4%) of total subjects were under one or more significant distress, and they showed significantly lower mean FACT-B total score than patients without distress(82.91 vs. 107.20, p<0.001). Distress was negatively correlated with the quality of life to a significant level even in patients who were in normal range of distress scale scores. Conclusion : These results support the importance of regular screening and proper management of distress for breast cancer patients.

During the screening for anti-complementary activity from 10 kinds of edible mushrooms, an alkali extract of Agaricus bisporus showed the highest activity through the complement fixation test. The crude anti-complementary material(AB-0) from Agaricus bisporus was obtained by the alkali extraction using 1 N NaOH containing 5% urea$(65^{\circ}C)$, followed by methanol reflux, dialysis and lyophilization. The fraction AB-O showed potent anit-complementary and anti-tumor activity against sarcoma-180 injected mice. The fraction AB-0 was divided into 5 fractions(AB-20, AB-40, AB-60, AB-80, AB-A) by gradual acetone precipitation. Among them fraction AB-20 having the highest activity and yield was found to contain 39% carbohydrate and 46% protein. The anti-complementary protein-bound polysaccharide AB-20 consisted of glucose, arabinose, xylose, galactose and mannose in a molar ratio of 6.49 : 1.98 : 1.24 : 1.00 : 0.71, respectively and its main component amino acids were alanine(20.59%), isoleucine(16.85%), glutamine+glutamic acid(14.12%) and leucine (13.83%). The anti-complementary activity of AB-20 was decreased greatly by periodate oxidation, but decreased slightly by pronase digestion. This indicates that polysaccharide moiety is corelated with the anti-complementary activity and that protein is also involved in the activity.

This study was conducted to identify the effects of repeated cardiopulmonary resuscitation (CPR) training using smart learning on nursing students' knowledge, self-efficacy, and clinical competency. A quasi-experimental nonequivalent control group, pretest-posttest design was used. The subjects of the study were 102 nursing college students who had received CPR training for 6 months. The CPR training was divided into smart learning, lecture education, and practical education. Data were collected from November to December, 2016 and analyzed by descriptive statistics, ${\chi}^2$-test, t-test and one way ANOVA using the SPSS/WIN 21.0 program. The scores of cardiopulmonary resuscitation knowledge were higher in the lecture education group than the practical education group and the smart learning group. Scheffe's post hoc test revealed a statistically significant difference among groups (F=8.23, p=<.001). The self-efficacy of the practical education group was higher than that of the lecture education group and smart learning group, but this difference was not significant (F=2.46, p=.091). The clinical competency of the practical education group and smart learning group were higher than that of the lecture education group. Scheffe's post hoc test revealed that the value of clinical competency differed significantly among groups (F=59.90, p=<.001). Overall, the results showed that effective education differs based on nursing students' knowledge, self-efficacy, ad clinical competency. Combination training would be required for more effective repeated cardiopulmonary resuscitation training.

This study was conducted to identify the effects of baby care using dolls on nursing students' major satisfaction, class satisfaction, and knowledge of newborn care. A quasi-experimental nonequivalent control group, pretest-posttest design was used. The subjects of the study were 95 nursing college students who agreed to participate. The control group (n=47) received lecture education consisting of watching newborn videos while the experimental group (n=48) received a practical education involving caring for a doll resembling an infant. Data were collected from March to May, 2019 and analyzed using descriptive statistics, χ²-tests, and t-tests with the SPSS/WIN 21.0 program. The major satisfaction score of the experimental group was higher than that of the control group, but it was not statistically significant (t=1.64, p=.107). The score for class satisfaction differed significantly between the experimental group and control group (t=2.08, p=.043). The knowledge of newborn care score for the experimental group was higher than that for the control group, and there was a statistically significant difference (t=-5.82, p<.001). Overall, the results show that baby care using a doll has positive effects on class satisfaction and knowledge of newborn care. In the future, it will be necessary to develop and apply effective teaching methods in line with the times.

Objective: To compare the clinical outcomes between oral micronized progesterone and dydrogesterone as a luteal phase support in stimulated intrauterine insemination (IUI) cycles. Methods: A retrospective analysis was performed in 183 IUI cycles during January 2007 to August 2009. Superovulation was achieved by using gonadotropins combined with or without clomiphene citrate. The luteal phase was supported by oral micronized progesterone 300 mg/day (n=136 cycles) or dydrogesterone 20 mg/day (n=47 cycles) from day of insemination. Results: There were no significant differences in clinical characteristics such as age of female, infertility factors, number of mature follicles ($\geq$16 mm), total motile sperm counts, and endometrial thickness on triggering day between the two groups. The clinical pregnancy rates per cycle were similar between the two groups (21.3% in the micronized progesterone group vs. 19.1% in the dydrogesterone group, p=0.92). The clinical miscarriage rate tended to be 3-fold higher in the micronized progesterone group (34.5% vs. 11.1%, p=0.36). Conclusion: Supplementation of oral dydrogesterone as a luteal support has similar clinical outcomes compared with oral micronized progesterone. Large-scaled randomized study would be required to confirm our findings.

Government has accounted an R&D investment on drug development for the highest share among biotechnology sector. Since competitive investments between each agencies, issues on efficiency or effectiveness of the duplicate investments have been raised continuously. In this research, we investigated the effectiveness of the investment through analysis of portfolio on drug development R&D, journals, patents, and performance of the each process. As a result, reliable technology for current market demands could not compute productive outcome at the early process of the development. On the other hand, grants which support non-clinical process of the development has produced the high-quality patents for active utilization. Moreover, analysis of the performance of the process, which affects rate of success on the drug development, showed decreased efficiency compared to global average. Therefore, we proposed the strategies of reflecting the market demands and bridging between stages without interruption for maximizing the efficiency and effectiveness on investment of drug development R&D. Furthermore, strategies for concentrated support on each process should be prepared for the success of final drug development.

Optically compensated bend liquid crystal display (OCB-LCD) has many application fields owing to its fast response time and wide viewing angle. However, in order to operate the OCB-LCD in bend state, this device needs quick transitions from the initial splay state to bend state. Unlike conventional approach using transient high voltage for the transition, the OCB-LCD with high surface tilt angle, which was achieved by polymerization of UV curable reactive mesogen monomer under certain voltage, was manufactured and the cell showed bend state initially. Electro-optic and electrical characteristics of the cell were analyzed. The cell shows a fast response time owing to high surface pretilt angle and very low residual DC less than 0.1 V although another polymer layer is formed above polymer alignment layers.
