This study aims to diagnose the present condition of the Digital comics industry, including the "webtoon", which is receiving attention as the new Korean wave (Hallyu) cultural content, and explore ways to vitalize these contents. Considering the fact that the distribution rate of smart devices in Korea is the highest in the world as of June 2013, and that comics as contents have been known to show the easiest and fastest adaptation to changes in the media, the Digital comics industry is certainly an area with high expected growth, but its actual size of the industry shows a very low growth rate compared to other digital contents. This study analyzes the present condition of the Digital comics industry through theoretical and precedent study, and deducts 7 major factors that inhibit the growth of Digital comics industry by summing up the industry structure through making surveys of major businesses in the industry. Further, problems and possible solutions of the digital comics industry are discussed through in-depth interviews with total 10 digital comics industry experts. Building a ecosystem based charged service, realizing a total management system, government support and improvements on restrictions are discussed as solutions to a sustained growth of the Digital comics industry.

This study attempts to analyze the structure of the knowledge and duties of the vocational counseling service industry by using the text mining method and network analysis, which are methods of big data analysis. The subjects of the survey were vocational counseling, job placement and career change support, three fields in the unit elements of competence included in the National Competency Standards (NCS) which areproposed by the government. Although the analysis results of frequently used words showed that all three fields had independent duties, many were overlapping, such as counseling, examination, employment support, etc. for clients, job seekers, and others. The knowledge required by the employees of this field includes many new fields, such as start-up development, lifelong career consulting, job adaptation and culture conflict, besides the five subjects of vocational psychology, vocational counseling, labor market, job information, and law, which are included in the vocational counselor certification examination. Also, we suggested that the consultants adhere to emotional approaches, such as empathy, acceptance and attentiveness, and take a neutral stance. This study isvaluable in that it is the first attempt to objectively analyze the duties of the vocational counseling service field by big data analysis. In addition, it is also meaningful that we first confirmed the difference between the direction of government policy and the actual practice in the field.

A multicast tree includes several, possibly a large number of, paths connecting source-receiver pairs, and network failure may disable part of the multicast tree. Reconstruction of the entire multicast tree to recover from a component failure is highly undesirable, because some group members have to suffer service disruptions even though the communication paths to/from them are not affected by the failure. To limit reconfiguration region and to maximize the likelihood of successful reconfiguration, we propose and evaluate a pre-planned reconfiguration policy for QoS multicast sessions. Specifically, we equip a reconfiguration path (RP) with each end-to-end path that connects a source-receiver pair in the multicast tree, and reserve resources in advance along the RPs. Efficient resource-sharing techniques are applied to reduce the amount of resources reserved for RPs but not used in the absence of failures. This way, we prevent uncontrolled competition among different multicast sessions which may simultaneously try to recover from failures. We evaluate the performance of the proposed scheme using simulation on randomly-generated networks. We use the shortest-path routing for QoS multicast sessions, and simulate both source-based and shared multicast trees. The evaluation results indicates that successful pre-planned reconfiguration can be achieved for all group members with reasonable overhead. Our scheme is also shown to adapt well to dynamic changes of group membership.

The purpose of this study was to identify factors affecting nursing professionalism in students and develop educational programs. Data were collected from 169 students in G-do, from March 15th to April 30th, 2019. Analysis was done using IBM SPSS 21.0 for frequency, percentage, average, standard deviation, t-test, ANOVA, Pearson correlation coefficient, and Multiple regression. The subjects' moral self was 3.39, moral behavior was 3.72, self-control was 3.68, empathy was 3.53, interpersonal competence was 3.69, and nursing professionalism was 3.90. Nursing professionalism positively correlated with self-control, empathy, and interpersonal competence. The most important factor affecting nursing professionalism was major satisfaction - 'satisfied' (β=.232, p=.002), followed by empathy (β=.222, p=.003) and interpersonal competence (β=.178, p=.016). The explanatory power was 18.5% (F=13.69, p<.001). Therefore, a program promoting major satisfaction, empathy, and interpersonal competence and a customized program considering personality and department adaptation are needed for establishment and enhancement of nursing professionalism. Utilizing the results of this study as basic data for nursing professionalism enhancement program and study confirming enhancement is expected.

This study has an objective of suggesting the ways to improve infant's sense of self-respect and peer competence, by examining what effect infant temperament has on infant's sense of self-respect and peer competence. The notable study results through analysis are as follows; First, it was shown that, in regard with adaptability and activity of infant temperament, cognitive ability of the sense of self-respect and peer acceptance, the average score of day care centers was higher, while it was shown that, in regard with response of infant temperament, the sense of self-respect's mother acceptance, peer relationship, sociability of peer competence, the average score of kindergartens was higher, and the boy infants' physiological regularity was shown to be higher than that of girl infants. Second, as a result of looking into the difference of infant temperament, sense of self-respect, and peer competence according to infant's age, we found that, in case of 'response' of infant temperament, age 5 group was classified into 'group a', and age 3 and 4 group was classified into 'group b', and two groups showed the difference, and in case of 'physiological regularity', age 3 group had the biggest regularity while age 5 group had the relatively low regularity, thus two groups showed the difference. In regard with sense of self-respect and peer competence, it was shown that age 4 and 5 group had higher one than that of age 3 group.

Currently our country has very serious problems of traffic congestion and urban environment due to increasing automobile ownership. Recently, our concern about environmentally sustainable transportation and green transportation is increasing, so the government is pushing ahead the policy of bicycle using activation. So it is needed to develop a model to analyze the service level of bicycle roads more realistically. In this study, a neuro-fuzzy inference model to analyze the service level of bicycle roads was built selecting the width of bicycle roads, the number of conflicts during cycling and pedestrian volume, which have fuzzy characteristics, as input variables. The predictability of the model was evaluated comparing the surveyed and the estimated. The values of the statistics, $R^2$, MAE and MSE were 0.987, 0.142, 0.032. Therefore, It may be judged that the explainability of the model is very high. The service levels of bicyle roads estimated by the model are 1~3 steps lower than KHCM assessments. The reason may be explained that the model estimates the service level considering the width of bicycle roads and the number of conflicts simultaneously besides pedestrian volume.

In this paper, we construct the TMO-based object group model on distributed environment, and analyze and evaluate the executability for distributed real-time service of our object group model by developing the distributed real-time application simulator applying the model. The Time-triggered Message-triggered Object(TMO) is a real-time server object having real-time property itself. The TMO-based object group is defined as a set of objects which logically reconfigured the physically distributed one or more TMOs on network by a given distributed application. For supporting group management of the server objects, the TMO-based object group we suggested provides the functions which register and withdraw the solver objects as a group member to an arbitrary object group, and also provides the functions which insert and delete the access rights of server objects from clients. Also, our model was designed and implemented to support the appropriate object selection and dynamic binding service for a single TMO as well as the duplicated TMOs, and to support the real-time scheduling service for the clients which are requesting the service. Finally, we developed the Defence System against Invading Enemy Planes(DSIEP) simulator as a practical example of distributed real-time application by applying our model, and evaluated the adaptability of distributed service strategies for the group components and the executability of real-time services that the TMO-based object group model provides.

The advent of e-government following the information revolution has affected public records systems. Records management should now be changed into an environment for establishing a national records management system based on the Internet of things (IoT), cloud, big data, and mobile (ICBM), and it is time to make a fresh start toward a next-generation records management system that responds to changes in the environment. Ultimately, it is time for a records management system that ensures a proper way of dealing with new environmental changes. It has been nearly 20 years since the Public Records Management Act was enacted in 1999, and its complete amendment was made in 2006 so that electronic records could be efficiently managed. When recompliance management needs to be rechecked, a full redesign is required to enable the current legal system to respond to the new circumstances in the present day. Therefore, this study is intended to suggest ways to improve the new records management legal system as the environment changes over the next generation and lay the legal groundwork for innovation in the national records management system.

Estuarine wetlands, which form a distinctive brackish water zone, serve as important habitats for organisms that have adapted to and thrive in this environment. Nonetheless, excessive development and utilization result in artificial disruptions that alter the distinctive functions and attributes of estuarine wetlands. To collect the basic data for the conservation of estuarine wetlands with excellent ecosystems, we investigated the vegetation distribution characteristics and biota status of the Taehwagang River Estuarine Wetland. Data from vegetation surveys have shown that 25 plant communities of six physiognomic vegetation types, including willow vegetation, lotic and lentic herbaceous vegetation, floating/submerged vegetation. In the upper reaches, where topographical diversity was high, various types of wetland vegetation were distributed. In terms of biodiversity, a total of 696 species, including 7 endangered wildlife species, were identified. Due to good ecological connectivity, tidal rivers are formed, brackish water species including various functional groups are distributed around this section. The inhabitation of various water birds, such as diving and dabbler ducks, were confirmed according to the aquatic environment of each river section. The collection of ecological information of the Taehwagang River Estuarine Wetland can be used as a framework for establishing the basis for conservation and management of the estuarine ecosystem and support policy establishment.

In recent years, international migration of professional workers is significantly increasing as globalization has been deepened more and more. South Korea is not an exception for this case. Immigration of professional workers have steadily increased since 2000 in Korea, and the number reached approximately to 50,000 in 2009. In addition, it is a major trend that immigrants of short-sojourn are decreasing and ones of long-sojourn increasing. Our research shows that foreign language instructor has the greatest number of foreign professional immigrants. The next is professional immigrants related to business-activities. There are considerably entertainers, but they have greatly decreased since 2003. Majority of foreign professional immigrants settle down in a few metropolises. Especially, they reside in Seoul Metropolitan Area and Southeast coastal region. Professional immigrants trend to do with Korean on the base of their offices rather than residental communities in terms of adaptation, and they do not have strong will to reside permanently in Korea. Moreover, they are located at a blind spot of Korean government's foreign immigrant policy, comparing to foreign workers and female marriage immigrants.
