The problem solving processes of elementary school children who are talented in science have been seldom studied. Researchers often resort to thinking aloud method to collect data of problem solving processes. The major purpose of the study is investigating high ability elementary school students' problem solving processes through the analysis of written responses to science problems in everyday context. 67 elementary students were participated Chungcheongbuk-do Elementary Science Contest held on October, 1997. The written responses of the contest participants to science problems in everyday context were analyzed in terms of problem solving processes. The findings of the research are as follows. (1) High ability elementary students use various concepts about air and water in the process of problem solving. (2) High ability elementary students use content specific problem solving strategies. (3) The problem solving processes of the high ability elementary students consist of problem representation, problem solution, and answer stages. Problem representation stage is further divided into translation and integration phases. Problem solving stage is composed of deciding relevant knowledge, strategy, and info..ins phases. (4) High ability elementary students' problem solving processes could be categorized into 11 qualitatively different groups. (5) Students failures in problem solving are explained by many phases of problem solving processes. Deciding relevant knowledge and inferring phases play major roles in problem solving. (6) The analysis of students' written responses, although has some limitations, could provide plenty of information about high ability elementary students' problem solving precesses.

Lately each country tends to provide neutrality and ease of enforcement in order to settle disputes related to international trade through commercial arbitration. In order to expand the use of arbitration systems, most countries accept arbitration agreements as an effective tool agreed between parties that express their intent to settle disputes by the arbitration. It is applied equally to selective arbitration agreements and parties can select either arbitration or lawsuit to settle disputes based on the contract intent for selective arbitration agreements. However, China does not admit the effectiveness of selective arbitration agreements. Chinese courts regard selective arbitration agreements as not valid because the contract of a selective arbitration agreement between parties is not a definite expression to only use the arbitration and there is no exclusion of court jurisdiction. Therefore, the study attempts to consider effective conditions for selective arbitration agreements in the Chinese arbitration act and other relevant regulations, and also verifies the judgment by Chinese courts on relevant disputes. As a result, the study explores some problems and implications of Chinese selective arbitration agreements and suggests some precautions in case Korean companies pursue selective arbitration agreements with Chinese enterprises and investors.

Purpose: With the decrease in available clinical sites, a decrease in adequately prepared clinical faculty, and demand to prepare health care students to begin work, we need alternative methods to teach clinical skills for health care professionals. The use of simulation as an educational process that can replicate clinical practices is becoming popular in nursing. Therefore, this study was conducted to review directions of simulation-based learning in nursing education. Methods: A systematic review of quantitative studies was undertaken using Medline, KERIS, and KISS. The primary search terms were simulation and nursing. Reference lists from relevant papers and the websites of relevant nursing organizations were also searched. Nine studies met inclusion criteria and were analyzed in detail. Results: All studies reported simulation as a valid teaching/learning strategy. Six of the studies (66.7%) showed that simulation technology was a practical and successful model to use in teaching a variety of clinical skills for nursing students and nurses. Conclusion: Simulation may have some advantages over other teaching methods, depending on the scenario, context, topic, and method. Further study is needed to determine the effect of team size on learning and to develop a universal method of outcome measurement.

As the Law on the Prevention of Domestic Violence was enacted in Korea, it has become necessary to work on how to intervene effectively in Korean men who batter. The purpose of this study is to establish the framework of the intervention model which is relevant to Korean wife-batterers. In the States, the psychoanalytic model, cognitive-behavioral model, and feminist model are most widely used with men who batter. As yet, the consensus on which model is most effective has not been reached. In this study, each model is reviewed briefly. And then it is suggested that in the light of Korean culture the educational model is more relevant than therapeutic model. Several points are also suggested, which need to be considered when feminist model is used in Korean culture. It is also insisted that the integrated model based on ecological theory is necessary to intervene effectively in such a multi-dimensional problem as domestic violence. For the group intervention, it is suggested to use educational model primarily and to use therapeutic model complementarily. Based on the framework suggested in this study, to develop the specific structure of the program, to implement it, and to test its effectiveness will be the tasks of the future researches.

With the recent spread of digital content, more people have been watching the digital content of TV programs on their PCs or mobile devices, rather than on TVs. With the change in such media use pattern, genres(types) of broadcast programs change in the flow of the times and viewers' trends. The programs that were broadcast on TVs have been released in digital content, and thereby people watching such content change their perception. For this reason, it is necessary to newly and differently classify genres(types) of broadcast programs on the basis of digital content, from the conventional classification of program genres(types) in broadcasting companies or relevant industries. Therefore, this study suggests a plan for newly classifying broadcast programs through using machine learning with the log data of people watching the programs in online media and for applying the new classification. This study is academically meaningful in the point that it analyzes and classifies program types on the basis of digital content. In addition, it is meaningful in the point that it makes use of the program classification algorithm developed in relevant industries, and especially suggests the strategy and plan for applying it.

In this work, a review of mechanical metamaterials and seismic protection systems that use them is carried out, focusing on passive protection systems. During the last years, a wide variety of classical systems of seismic protection have demonstrated to be an effective and practical way of reducing the seismic vulnerability of buildings, maintaining their health and structural integrity. However, with the emergence of metamaterials, which allow obtaining uncommon mechanical properties, new procedures and devices with high performance have been developed, reducing the seismic risk through novel approaches such as: seismic shields and the redirection of seismic waves; the use of stop band gaps and the construction of buried mass resonators; the design of pentamodal base isolators. These ideas are impacting traditional areas of structural engineering such as the design and building of highly efficient base isolation systems. In this work, recent advances in new seismic protection technologies and researches that integrate mechanical metamaterials are presented. A complete bibliometric analysis was carried out to identify and classify relevant authors and works related with passive seismic protection system based on mechanical metamaterial (pSPSmMMs). Finally, possible future scenarios for study and development of seismic isolators based on mechanical metamaterials are shown, identifying the relevant topics that have not yet been explored, as well as those with the greatest potential for future application.

Smart hospitals involve the use of recent ICT (information and communications technology) technologies to improve healthcare access, efficiency, and effectiveness. Standardization in smart hospital technologies is crucial for interoperability, scalability, policy formulation, quality control, and maintenance. This study reviewed relevant international standards for smart hospitals and the organizations that develop them. Specific attention was paid to robotics in smart hospitals and the potential for standardization in this area. The study used online resources and existing standards to analyze technologies, standards, and practices in smart hospitals. Key technologies of smart hospitals were identified. Relevant standards from ISO (International Organization for Standardization) and IEC (International Electrotechnical Commission) were mapped to each core technology. Korea's leadership in smart hospital technology were highlighted. Approaches for standardizing smart hospitals were proposed. Finally, potential new international standard items for robotics in smart hospitals were identified and categorized by function: sampling, remote operation, delivery, disinfection, and movement tracking/contact tracing. Standardization in smart hospital technologies is crucial for ensuring interoperability, scalability, ethical use of artificial intelligence, and quality control. Implementing international standards in smart hospitals is expected to benefit individuals, healthcare institutions, nations, and industry by improving healthcare access, quality, and competitiveness.

Ovarian cancer is the most lethal world-wide gynecological disease among women due to the lack of molecular biomarkers to diagnose the disease at an early stage. In addition, there are few well established relevant animal models for research on human ovarian cancer. For instance, rodent models have been established through highly specialized genetic manipulations, but they are not an excellent model for human ovarian cancer because histological features are not comparable to those of women, mice have a low incidence of tumorigenesis, and they experience a protracted period of tumor development. However, the laying hen is a unique and highly relevant animal model for research on human ovarian cancer because they spontaneously develop epithelial cell-derived ovarian cancer (EOC) as occurs in women. Our research group has identified common histological and physiological aspects of ovarian tumors from women and laying hens, and we have provided evidence for several potential biomarkers to detect, monitor and target for treatment of human ovarian cancers based on the use of both genetic and epigenetic factors. Therefore, this review focuses on ovarian cancer of laying hens and relevant regulatory mechanisms, based on genetic and epigenetic aspects of the disease in order to provide new information and to highlight the advantages of the laying hen model for research in ovarian carcinogenesis.

Existing image search systems allow users to search images by keywords, or by example images through content-based image retrieval (CBIR). On the other hand, users might learn more relevant textual information about an image from its text captions or surrounding contexts within documents or Web pages. Without such contexts, it's difficult to extract semantic description directly from the image content. In this paper, we propose an annotation watermarking system for users to embed text descriptions, and retrieve more relevant textual information from similar images. First, tags associated with an image are converted by two-dimensional code and embedded into the image by discrete wavelet transform (DWT). Next, for images without annotations, similar images can be obtained by CBIR techniques and embedded annotations can be extracted. Specifically, we use global features such as color ratios and dominant sub-image colors for preliminary filtering. Then, local features such as Scale-Invariant Feature Transform (SIFT) descriptors are extracted for similarity matching. This design can achieve good effectiveness with reasonable processing time in practical systems. Our experimental results showed good accuracy in retrieving similar images and extracting relevant tags from similar images.

The purpose of this paper is to provide corpus-based quantitative analyses of HEART and HEAD in order to examine their actual usage status and to consider some cognitive linguistic aspects associated with their use. The two corpora COCA and COHA are used for analysis in this study. The analysis of COCA corpus reveals that the total frequency of HEAD is much higher than that of HEART, and that the figurative use of HEART (60%) is two times higher than its literal use (32%); by contrast, the figurative use of HEAD (41%) is a bit higher than its literal use (38%). Among all four genres, both lexemes occur most frequently in fictions and then in magazines. Over the past two centuries, the use of HEART has been steadily decreasing; by contrast, that the use of HEAD has been steadily increasing. It is assumed that the decreasing use of HEART has partially to do with the decrease in its figurative use and that the increasing use of HEAD is attributable to its diverse meanings, the increase of its lexical use, and the partial increase in its figurative use. The analysis of the collocation of verbs and adjectives preceding HEART and HEAD, as well the modifying and predicating forms of HEART and HEAD also provides some relevant information of the usage of the two lexemes. This paper showcases that the quantitative information helps understanding not only of the actual usage of the two lexemes but also of the cognitive forces working behind it.
