In this paper, we present a WebRTC-based emergency video call system structure that builds a service system in a constant monitoring environment to increase the usability and stability of elevator emergency call devices. The proposed system provides a smooth call environment between the emergency call system in the elevator and maintenance managers in case of an emergency, performs rapid response processing to elevator emergency calls through monitoring of the target elevator, and handles any emergency calls that may occur in the physical space of the elevator. The purpose is to build an environment that can implement low-latency, real-time video call services of voice and video by overcoming the physical constraints required for video calls. To this end, we have established a service environment based on OpenAPI, which is currently used in various fields and its performance has been proven, and provides video calls and emergency situation dissemination through rapid messaging by providing low-latency call quality. The presented system structure will be able to provide a basis for expanding various functions and constructing a reliable service environment and intelligent model for the elevator system through combination with the elevator control panel and various devices.

The wireless mesh network based on IEEE 802.11s provides a routing based on a destination address as it inherits legacy internet architecture. However, this architecture interested in not 'what' which is originally the users goal but 'where'. Futhermore, because of the rapid increase of the number of mobile devices recently, the mobile traffic increases geometrically. It reduces the network effectiveness as increasing many packets which have same payload in the situation of many users access to the same contents. In this paper, we propose an OpenFlow-based contents routing for the wireless mesh network(WMN) to solve this problem. We implement contents layer to the legacy network layer which mesh network uses and the routing technique based on contents identifier for efficient contents routing. In addition we provide flexibility as we use OpenFlow. By using this, we implement caching technique to improve effectiveness of network as decreasing the packet which has same payload in WSN. We measure the network usage to compare the flooding technique, we measure the delay to compare environment using caching and non caching. As a result of delay measure it shows 20% of performance improve, and controller message decrease maximum 89%.

The open inquiry is one of the representative learning approaches for gifted students. However, a gifted student should develop various complicated competencies to succeed in the open inquiry because of its complexity. This study develops a question list in accordance with each stage of inquiry so that the list could provide scaffolding in the process of open inquiry and students develop near-professional competencies and produce distinguished outcomes. For the purpose, we have reviewed various literatures related to research methodologies, academic writings, and learning of inquiry. Based on the review, we identified the open inquiry as cognitive, metacognitive, and sociocultural processes and set up the direction of the development of the question list. We also have elaborated the goals of the open inquiry, provided a model of the stage of inquiry, and developed the guiding question list belonging to each stage. As a discussion, we provided several noteworthy issues in the situation of when the list is used in the teaching of the open inquiry for the gifted.

Plan S is a policy that mandates research papers supported by specific funders such as the European Community be published in open access journals. The funder supports APC to researchers, providing a chance to advance the era of gold open access, and is expected to bring significant changes to the scholarly publishing ecosystem. This study explored the impact of Plan S from the perspective of each stakeholder of the scholarly publishing ecosystem, such as funders, academic societies or publishers, authors, and libraries, through a review of previous studies. In addition, the status of Korean gold open access publishing and position for each stakeholder were identified through the collected data analysis. As a result of the analysis, the share of publishing gold open access journals in Korea was 22%, which was less than 26% worldwide. Korean funding agencies were predicting and preparing for the impact of Plan S. On the other hand, Korean academic societies produce about 70% of all papers, but there are not many open access papers except medicine (51%). The response of the Korean library was not sufficient, and it contrasted with the activities of librarians in the U.S. that actively provide research support services based on the research lifecycle. It was suggested that Korean libraries should also actively try to change the role of librarians; advising researchers to plan open access publishing in grant project applications, consulting on copyrights, and so on. This study identified the background, principles, and impact of Plan S policy that would be effective in 2021 and examined the response situation in Korea. This study is valuable in that it served as the necessary basis for revitalizing the academic publishing ecosystem in Korea.

The purpose of this study was to suggest an instructional direction for improving scientific problem-finding ability. For this purpose, the present study made an in-depth analysis about activity on problem finding tasks of high school students in an ill-structured scientific problem situation. Subjects were divided into two groups (cooperative and individual) and two kinds of problem finding tasks were administered to two groups. Results indicated that a cooperative activity on problem finding happened to a series of steps exploring problem situation, expressing knowledge and experience, discussing provisional problems, creating various problems and selecting the best problem. Besides, a cooperative activity on problem finding depended heavily on prior knowledge and experience, and in the meantime, various scientific concepts turned out to naturally be expressed. As for the problems found out during a cooperative activity, their scores in creativity factors, including the degree of agreement in original problem selection came out to be on the whole, as excellent. In addition, the types of the problems found out in open problem situation showed that they were more various than those found out in closed problem situation. Subjects perceived that activity on problem finding had positive influence on scientific concept and science process skills. Findings of this study have the following educational implications: First, it is needed to prepare for educational environment that enables students to explore various knowledge and information. Second, the offering of various opportunities is needed to enlarge the scope of scientific knowledge and experience. Third, it is needed to prepare for a study atmosphere that lets students express their knowledge and experiences freely.

This study is on the concept of Gunter Behnisch' s 'Situationsarchitektur'. Gunter Behnisch is known as the architect who have produced astonishing variety of different types of buildings since 1950s. His works always reflect his changing major concerns of architecture, which varied through his career such as flexibility and serial production in the 1960s, politics and place in the 1970s and 80s, and ecological issues in 90s and afterward. Behnisch says that the goal of architects' work is not so much the building as the situation to be created, and only such measures should be taken as in fortunate cases strengthen and give meaning to the situation that exists, or in less fortunate ones recreate it. The 'Situationsarchitektur' is realized through emphasizing transparency, humanity, public space, and open detail that could lead to a certain lightness and relaxedness in architecture not as an end in itself, but rather in the result. Architecture should be allowed to arise out of circumstances of use and construction, but form should not be imposed as a preconception. Also architecture should be strongly tied to time, space and local conditions. Behnisch tries to see the fundamentals of his work in such a way that subtlety and diversity develop of their own accord or are preserved as a reflection of a world.

In the modern society, social activities of married women are increasing along with the economic growth, which leads to low birth rates of the situation where most people give birth to only one or two children. Korea in particular records one of the lowest birth rates among many other nations of the world. Despite the situation where overall industrial consumer economy is not good, baby goods market is becoming more luxurious and diversified, and its scale is also growing. Desires of young parents in their 20s and 30s for their children leads to consumption desires of luxurious baby goods, and despite the fact that their taste level rises by easily gaining access to immense baby information via the Internet, our nation's baby furniture market is unreasonably lacking the ability to satisfy the needs of such consumers. Furniture culture of our nation today is based on the stand-up culture of the West. However, analyzing the life culture inside our homes, stand-up and sit-down cultures of the West and the East are coexisting complexly. Such life pattern can be more easily found in households with babies. As such, baby furniture that satisfies our unique life culture and has quality, design and price competitiveness is desperately needed. In such market state, this study is expected to make economic and cultural accomplishments by focusing on the newly embossing baby furniture market and developing products, delivering them to consumers to open new markets and developing into an industry.

The purpose of this study was to provide fundamental data for determining contents of Fundamental Nursing Practice and developing desirable bedside nursing techniques for clinical nursing areas. Subjects for this study were 86 nurses who were employees of two university hospitals located in Seoul and a district area. Data were collected by questionnaires. Items of Fundamental Nursing Practice were classified into 72 items according to the result from content analysis of 9 textbooks of Fundamental Nursing. The results are as follows : 1) Items which above 80% of respondents practiced during the school inside practice or clinical nursing practice course were axillary temperature measurement, radial pulse measurement, respiratory rate measurement, application of oral hygiene, hand-washing technique, application of hot and cold bags, intramuscular injection technique, open bed-making, soap enema method, application of nelaton catheterization and oral and nasal suction methods. 2) Above 90% of respondents replied that all items except temperature measurement and bed-making were requisite contents for Fundamental Nursing Practice. Above 10% of respondents replied oral and rectal temperature measurement and bed-making were unnecessary content. 3) Above 90% of respondents replied that operating methods of all items except isolation technique, admission and discharge procedures, and retention enema in the Fundamental Nursing Practice course and clinical situation were consistent. The main reasons that respondents did not apply methods which they learned in the Fundamental Nursing Practice course to the clinical situation were 'insufficient time', 'colleagues were using different methods', 'insufficient supply of instuments' or 'inappropriate appliances'.

Since the bank managers were accustomed to be under the goverment policy and control so far, all what they had to do were just to follow the government policy and wait for customers. These usual practices resultedin neglection of concerns for innovation and competitive power. However, it currently happens the change of business environment such as the liberalization of interest rates and the open finance market policy. Thus, it is necessary for the bank managers to have a concern on that situation for the improvement of profitability through productivity and cost-down. The bank managers are trying to set out an innovation strategy to cope with this situation. An innovation strategy should be based on its own characteristics of banking business. The banking business is different from those of other business because it deals with intangible services rather than material goods and thus, the bank managers have to be more sensitive to the customers. There also exists an inefficiency of internal process due to too many repetition of 'check and balance'. Thus, We set out the five principles and six selected tasks in order to settle down an inefficiency and to redesign a bank operation process.
