The purpose of this study is to investigate the seven-hour sexuality education program for senior high school girl students and apply it to them to find out how this program affects their sex-related knowledge, sexual attitudes, and the self-efficacy of sexual behavior practice. The ultimate goal of this study is that high school girl students are to prevent unwanted pregnancy, STD and AIDS, after attending this sexuality education program. A non-equivalent control group pretest-post test design was used for this study. The number of experimental group consisted of 80 girl students and the control group was composed of 80 girls, too. A total of 160 freshmen from two commercial girls' high schools were selected by a convenience sampling method. This study was carried out in commercial high schools located in Daejeon, Korea from July 15th to October 31st, 2002. To discover the need for sexuality education, the researcher surveyed with a pre-designed questionnaire to 160 girls from the two different commercial high schools. The sex education curriculum was developed on the basis of the need of high school girl students for sex education survey results and literature review and a teaching-learning planning model and health belief model. The experimental group was taught the sexuality education program for seven hours from October 19th to 23rd, 2002 and each period continued for 50 minutes. The SPSS(10.0) Windows statistics software was used to analyze the data, along with frequency, percentage, $X^2$-test, t-test, and paired t-test. The instruments' internal consistencies were tested by Cronbach's alpha coefficient. The results of this study were as follows: 1. The increment of sex-related knowledge score after seven hour sexuality education was significantly higher in experimental group (t=-10.88, p=.000). 2. The increment of sex-related attitude score after seven hour sexuality education was significantly higher in experimental group (t=-2.67, p=.009). 3. The increment of the practice of self-efficacy of sexual behavior score after seven hour sexuality education was significantly higher in experimental group(t=-4.95, p=.000). In conclusion, sexuality education programs based on high girl students' educational desire, characteristics of development, a teaching learning planning model, a health belief model were effective to improve sex-related knowledge, sexual attitudes and the self-efficacy of sexual behavior practice of commercial high school girl students. This result can contribute to expand the school nurse's role in the sex education area and to develop theory-based school health nursing.

Objectives: This study evaluated the effects and relevant factors of community-based education and advocacy intervention on stroke awareness among the general population. Methods: The study enrolled 505 community-dwelling adults aged 19 years or older who completed a survey before and after a community-based intervention held between May 2014 and December 2014. Trained staff collected data about knowledge of five stroke warning signs, emergency response, golden window of time (${\leq}3h$), and demographics. Results: After the intervention, public awareness of all five stroke warning signs increased significantly from 26.5% to 33.9% (p=0.011). Public awareness of the golden window of time also increased significantly from 70.1% in April 2014 to 75.8% in December 2014 (p=0.040). In a multivariate logistic regression analysis, older age, higher education level, and exposure to stroke-related public service announcements or educational materials were significant predictors of knowledge of all five warning signs for stroke. Conclusions: Comprehensive community-based intervention is effective for improving public awareness of the warning signs of stroke and the golden window of time.

With the rapid development and introduction of digital technologies, both everyday human life and technological processes of any production are changing, which stimulates the transformation of the economy and education. Digital technologies are not only a tool, but also a living environment of modern human, which opens up new opportunities: learning at any convenient time, continuing education, the ability to form individual educational learning trajectories and more. However, the digital environment requires teachers to take a modern approach to the organization of the educational process, the formation of new skills and abilities to work in the digital educational environment. As a result of the study, it was found that the system of vocational education should provide training for masters of industrial training who have a high level of digital competence. The purpose of the article is to single out, theoretically substantiate and determine the level of formation of structural components of digital competence of future masters of agricultural training. The structure of digital competence of agricultural master was analyzed on the basis of domestic and foreign scientists researches. Systematized research results indicate that digital competence consists of four components: motivational-value (combination of internal and external motives for the use of digital technologies in future professional activities), cognitive (a set of theoretical knowledge, skills and abilities of future master of industrial training to effectively build educational process with the use of digital technologies), activity-professional (expansion and deepening of knowledge, skills, necessary skills for effective implementation of digital technologies in the educational process) and evaluative-reflexive (ability to analyze and self-analyze own activities and its results taking into account professional characteristics, self-realization in professional activities through the use of digital technologies). These components are comparable with the indicators that describe the knowledge, skills and abilities needed by the future master of industrial training to organize the modern educational process. A questionnaire was conducted to determine the levels of this competence formation, which allows us to conclude that it is necessary to increase the level of formation of all components of digital competence of future masters of industrial training in agriculture. The results of the study can be used as a basis for the development of disciplines that form the special competencies of masters of industrial training in agriculture and programs of advanced training of teachers.

This study aims to analyze the network structure of technological innovation resources in SMEs, especially manufacturing firms, and reveal the differences between innovative and non-innovative firms. The study first analyzes connection centrality, flow-mediated centrality, and power centrality for all firms, and derives structural equivalence through CONCOR analysis. Then, the network structure of innovative and non-innovative firms was compared and analyzed according to innovation performance and creation. The results show that entrepreneurship and corporate innovation strategy have a significant impact on the analysis of technological innovation resources of all firms. According to the CONCOR analysis, the innovation resources of SMEs are organized into seven clusters, which can be defined as intrinsic product innovation resources, competitive advantage promotion resources, cooperative activities resources, information system resources, and innovation protection resources. The network analysis of innovative and non-innovative firms showed that innovative firms focused on enhancing competitiveness and improving quality, while non-innovative firms tended to focus more on existing products and customers. In addition, innovative firms had eight clusters, while non-innovative firms had six clusters, suggesting that innovative firms utilize resources diversely to pursue structural change and new value creation, while non-innovative firms operate technological innovation resources in a more stable form. This study emphasizes the importance of entrepreneurship and corporate innovation strategy in SMEs' technological innovation, and suggests that strong internal efforts are needed to increase innovativeness. These findings have important implications for strategy formulation and policy development for technological innovation in SMEs.

Objective: Detection of pneumoperitoneum using abdominal radiography, particularly in the supine position, is often challenging. This study aimed to develop and externally validate a deep learning model for the detection of pneumoperitoneum using supine and erect abdominal radiography. Materials and Methods: A model that can utilize "pneumoperitoneum" and "non-pneumoperitoneum" classes was developed through knowledge distillation. To train the proposed model with limited training data and weak labels, it was trained using a recently proposed semi-supervised learning method called distillation for self-supervised and self-train learning (DISTL), which leverages the Vision Transformer. The proposed model was first pre-trained with chest radiographs to utilize common knowledge between modalities, fine-tuned, and self-trained on labeled and unlabeled abdominal radiographs. The proposed model was trained using data from supine and erect abdominal radiographs. In total, 191212 chest radiographs (CheXpert data) were used for pre-training, and 5518 labeled and 16671 unlabeled abdominal radiographs were used for fine-tuning and self-supervised learning, respectively. The proposed model was internally validated on 389 abdominal radiographs and externally validated on 475 and 798 abdominal radiographs from the two institutions. We evaluated the performance in diagnosing pneumoperitoneum using the area under the receiver operating characteristic curve (AUC) and compared it with that of radiologists. Results: In the internal validation, the proposed model had an AUC, sensitivity, and specificity of 0.881, 85.4%, and 73.3% and 0.968, 91.1, and 95.0 for supine and erect positions, respectively. In the external validation at the two institutions, the AUCs were 0.835 and 0.852 for the supine position and 0.909 and 0.944 for the erect position. In the reader study, the readers' performances improved with the assistance of the proposed model. Conclusion: The proposed model trained with the DISTL method can accurately detect pneumoperitoneum on abdominal radiography in both the supine and erect positions.

The purpose of this study was to identify knowledge of universal precautions and its performance in practice. The research was conducted from November 2 to 30, 1998. A total 515 student nurses ; 249 from a baccalaureate nursing college and 266 from second and third year of a 3-year community nursing college were surveyed. The results are as following : 1. The average score for universal precautions knowledge was 270.41$\pm$19.43/300(range 150-300). The results showed that 99.2% of students avoid injury from used needles, 98.6% answered that they always wash their hands if they had contact with the patient's blood and they always dispose of used needles in special collectors (97.7%) for needles. But, 39.2% responsed that they dispose of used needles after recapping them. 2. The average score for universal precautions knowledge of the senior students in the 4-year college was the highest (277.65$\pm$13.99). 3. The average score for the performance of universal precautions knowledge was 53.18 $\pm$5.91(range 14-70). The items : ‘I cautiously avoid injury from the used needles’(4.92$\pm$0.33), ‘I always wash my hands if there has been contact with the patient's blood’(4.91$\pm$0.34), and ‘I always disposed of used needles in the appropriate collector’(4.89$\pm$0.42) showed the highest performance. However ‘I always dispose of used needles after recapping them’(2.19$\pm$1.39) and ‘I always use protection goggles when in danger of contamination’(2.19$\pm$1.20) showed low performance level. 4. The highest average score for universal precautions performance was shown among the second year students in 3-year nursing college (54.19$\pm$6.92) between the groups. It showed that the level of the universal precautions performance was higher for those who had education on university precautions prior to performance of the universal precautions than for those without any prior education. 5. The percentage of students who reported the experience of direct contact with patients' blood and/or body fluids was 42.30%. The experience of direct contact with blood and/or body fluids of the educational group was significantly higher than those were not educated. 6. The most frequent cause of the direct contact was ‘needle pricking and/or skin cut’(63.04%). The most frequent substance with which the students contact was ‘blood’(59.85%). The majority of the sample had answered that the mode of contamination was ‘unknown’(63.54%). The majority of the sample answered that strategies used after contamination included ‘washing with soap’(33.61%). Reviewing the chart of patients or asking other health professionals(28.85%). 7. The number of students who had the experience of a needle stick and/or skin cut was 145(28.16%). The clinical practice places where the incidents occurred were mainly in the internal medicine unit (45.07%) and the surgical unit (31.92%) followed by the intensive care unit and the emergency unit in order. The experience of a needle stick and/or skin cut happened during on intra-muscular injection 47.34% and intravenous injection 21.81%. The causes of the needle stick and/or skin cut were ‘putting the needle cap back on 77(35.81%)’. The number of students who took an appropriate post management blood test and/or vaccination was 27(18.62%). 8. The Pearson Correlation Coefficient between the knowledge of universal precautions and performance of universal precautions in practice showed a positive correlation.

In this paper, a compact 370 W high efficiency GaN(Gallium Nitride) HEMT(High Electron Mobility Transistor) power amplifier(PA) using internal harmonic manipulation circuits is presented for cellular and L-band. We employed a new circuit topology for simultaneous high efficiency matching at both fundamental and 2nd harmonic frequency. In order to minimize package size, new 41.8 mm GaN HEMT and two MOS(Metal Oxide Semiconductor) capacitors are internally matched and combined package size $10.16{\times}10.16{\times}1.5Tmm^3$ through package material changes and wire bonded in a new package to improve thermal resistance. When drain biased at 48 V, the developed GaN HEMT power amplifier has achieved over 80 % Drain Efficiency(DE) from 770~870 MHz and 75 % DE at 1,805~1,880 MHz with 370 W peak output power(Psat.). This is the state-of-the-art efficiency and output power of GaN HEMT power amplifier at cellular and L-band to the best of our knowledge.

Innovation is the development of new customers value through solutions that meet new needs, inarticulate needs, or old customer and market needs in value adding new ways. This is accomplished through more effective products, processes, services, technologies, or ideas that are readily available to markets, governments, and society. Innovation differs from invention in that innovation refers to the use of a better and, as a result, novel idea or method, whereas invention refers more directly to the creation of the idea or method itself. Therefore, the utilization of patents is the most important of the three aspects (creation, protection and utilization) in the patent system for getting to actual innovation. In order to increase the patent use, the rates of the applied patents to a real industrial process and the bargain and license of patent rights should be promoted. For promoting technological innovation substantially, there is necessary to escape from dichotomy of weakening or enhancing patent protection in the discussion on the changes of patent system for "Adequate patent guarantees". Furthermore, the legal and institutional improvements to enable the use of patent should be discussed together. Recently, open innovation is a new paradigm that assumes that firms can and should use external ideas as well as internal ideas, and internal and external paths to market, as the firms look to advance their technology" or "Innovating with partners by sharing risk and sharing reward." The boundaries between a firm and its environment have become more permeable; innovations can easily transfer inward and outward. The central idea behind open innovation is that in a world of widely distributed knowledge, companies cannot afford to rely entirely on their own research, but should instead buy or license processes or inventions (i.e. patents) from other companies. In addition, internal inventions not being used in a firm's business should be taken outside the company. In the era of open innovation, more flexible patent use strategy is essential. It is important that improvements for the legal system in order that patented technology can be applied for products and processes in a real industrial between outside and inside of the firms.
