Two nurses' assications were organized in Korea during Japanese colonial period One was Choseon Ganhoboohoi(朝餘看護續會, the Korean Nurses' Association)started in 1923 and the other was Choseon Ganhoboohoiphoi started in 1924. Two nursing associations were very different in their members and activities. Choseon Ganhoboohoi was organized and lead by Western missionary nurses in Korea and their Korean pupil nurses. The aim of Choseon Ganhoboohoi was to become a member of ICN. Choseon Ganhoboohoi united with the Western Graduate nurses' Association in Korea, tried to raise the standard of nursing education, and became a branch of Japan Imperial Nurses' Association. All was to become a member of ICN. It continued 15 years and was quite active. But after the half of 1930s Japan's ruling policy became more and more suppressive and western missionaries were expelled from Korea so it could not but discontinue it's activities. Choseon Ganhoboohoiphoi(朝鮮觸護續協會) was organized and lead by Korean nurses. The aim of it was to do the role of nurses by social activities. So it tried health education for the public, It continued only about 2 years, But the leaders of Choseon Ganhoboohoiphoi moved to women's liberation movement and Korean liberation movement and tried to solve the problems of colonized women. The organizations and activities of Choseon Ganhoboohoi and Choseon Ganhoboohoi were two trends to develop Korean nursing during Japaneses Colonial period. The former asked for international cognizance by the raise of nursing standard, and the latter asked for national cognizance by social activities. Although two nurses' associations were different in their ways but quite same in the aspect that both tried for the development of nursing in Korea. But the colonial situation prevented them from continuing their activities. This means that the colonial situation of national level influenced deeply on the development of nursing profession.

This study develops a forecasting method to estimate air cargo demand from ICN(Incheon International Airport) to all airports in EU with Seasonal Autoregressive Integrated Moving Average (SARIMA) Model using volumes from the first quarter of 2000 to the fourth quarter of 2009. This paper shows the superiority of SARIMA Model by comparing the forecasting accuracy of SARIMA with that of other ARIMA (Autoregressive Integrated Moving Average) models. Given that very few papers and researches focuses on air route, this paper will be helpful to researchers concerned with air cargo.

Aspergillus, Penicillium, and their teleomorphic genera have a worldwide distribution and large economic impacts on human life. The names of species in the genera that have been reported in Korea are listed in this study. Fourteen species of Aspergillus, 4 of Eurotium, 8 of Neosartorya, 47 of Penicillium, and 5 of Talaromyces were included in the National List of Species of Korea, Ascomycota in 2015. Based on the taxonomic system of single name nomenclature on ICN (International Code of Nomenclature for algae, fungi, and plants), Aspergillus and its teleomorphic genera such as Neosartorya, Eurotium, and Emericella were named as Aspergillus and Penicillium, and its teleomorphic genera such as Eupenicillium and Talaromyces were named as Penicillium (subgenera Aspergilloides, Furcatum, and Penicillium) and Talaromyces (subgenus Biverticillium) in this study. In total, 77 species were added and the revised list contains 55 spp. of Aspergillus, 82 of Penicillium, and 18 of Talaromyces.

The purpose of this study was to develop a Disaster Nursing Preparedness Response Competency(DNPRC) Scale in terms of convergence and to verify its validity and reliability. Based on ICN Framework of the Disaster Nursing Competencies, DNPRC was developed through literature review. Participants was 292 nurses. Content Validitys, Construct Validity, and Reliability was verified through the exploratory factor analysis and confirmatory factor analysis, Convergent validity was tested by Pearson's coefficient correlation between DNPRC and DPQ-N. DNPRC was 5point likert scale with a total 34 item, consisting of 3 3 factosr, 16item of preparedness,4 factors, 18item of response. The reliability was Cronbach's ${\alpha}=.96$. This study may be useful to identify a disaster nursing competency and its related factors for nurse, and to develop nursing intervention to imprive nurses' disaster nursing competency.

In this paper, we propose an activity-performer bipartite matrix generation algorithm for analyzing workflow-supported human-resource affiliations in a workflow model. The workflow-supported human-resource means that all performers of the organization managed by a workflow management system have to be affiliated with a certain set of activities in enacting the corresponding workflow model. We define an activity-performer affiliation network model that is a special type of social networks representing affiliation relationships between a group of performers and a group of activities in workflow models. The algorithm proposed in this paper generates a bipartite matrix from the activity-performer affiliation network model(APANM). Eventually, the generated activity-performer bipartite matrix can be used to analyze social network properties such as, centrality, density, and correlation, and to enable the organization to obtain the workflow-supported human-resource affiliations knowledge.

Seoul terminal maneuvering area (TMA) that includes Incheon International Airport (ICN) and Gimpo International Airport is a very congested airspace with around 1,000 daily flights and the airspace blocked at the boundary between Incheon flight information region (FIR) and Pyongyang FIR. Consequently, with frequency radar vectorings, separation assurance in this airspace is complicated thus resulting in higher controller workload. In this paper, the conflict and collision risks in Seoul TMA are analyzed using recorded ADS-B data for past three years. Using the recorded trajectories, original flight plan procesures and routes are reconstructed and the risks are quantified using detect and avoid well clear (DWC) metric that is developed for large unmanned aircraft system. The region west of ICN was found to be the highest risk area regardless of the runway directions. In addition, merge and crossing points between procedures displayed relatively high risks.

Named Data Networking (NDN) is a representative technology of ICN that realizes the future Internet architecture. NDN searches for data by its content and not by its host IP address. The consumer generates an interest packet and sends it to the NDN network. The NDN network uses three tables such as CS, FIB, and PIT and forwards the received interest packet to the next hop. The producer transmits the data packet to the consumer through a name-based forwarding scheme. In this paper, we design and implement an ndnSIM-based NDN network and perform performance evaluation. We analyze the ndnSIM structure and develop a 6-node congested NDN network and a 9-node grid NDN network using ndnSIM. In the simulation, the performance of latency and throughput of the interest packet rate are measured. We analyze the effect of congestion on the latency and throughput of the NDN network. This approach will help researchers in the future.

To enhance network efficiency, named-data networking (NDN) implements data caching functionality on intermediate network nodes, and then the nodes directly respond to request messages for cached data. Through the processing of request messages in intermediate node, NDN can efficiently reduce the amount of network traffic, also solve network congestion problems near data sources. Also, NDN provides a data authenticate mechanism so as to prevent various Internet accidents caused from the absence of an authentication mechanism. Hence, through applying NDN to various smart IT convergence services, it is expected to efficiently control the explosive growth of network traffic as well as to provide more secure services. Basically, it is important factors of NDN which data is cached and where nodes caching data is located in a network topology. This paper first analyzes previous works caching content based on the popularity of the content. Then ii investigates the hitting rate of caches in each node of a network topology, and then propose an improved caching scheme based on the result of the analyzation. Finally, it evaluates the performance of the proposal.

CCN(Content-Centric Network) enables users to retrieve content using the content's name. Researchers face critical challenges in terms of mobility. Since the routing information is part of the content name, when the provider moves, it is necessary to update all the routers routing information. However, this requires significant costs. In this paper, we propose PNPCCN(Proactive Neighbor Pushing CCN), considering the popularity and rarity of mobility support, for providers in CCN environments. Via simulation studies, we demonstrate that our solutions are effective in terms of shorter numbers of retransmitted Interest packets, and average download times and higher delivery ratios during mobility.

This paper introduces a new airspace design method for continuous climb operation (CCO). The optimization problem is formulated as Mixed-Integer Linear Program (MILP) to maximize the upper limits of altitude on the waypoints to facilitate continuous climb for aircraft. In the proposed method, the interactions with other flight procedures are considered as well as various aircraft flight performances. The proposed method is applied to one of the departure procedures of Incheon International Airport (ICN) to demonstrate its performances.
