Since the Economic Crisis at the end of 1997, unemployment rate soared up to the record-high 8.6% (February 1999) and, for youth aged 15~29, it was 14.6% (27.8% for aged 15~19). In spite of economic recovery after the crisis, new participants in labor market at the school-to-work transition have faced with difficulties in finding their first jobs and, even further, the ratio of youth at out-of the labor force but not in school has remained at a higher level. It is important to calibrate the negative effects of nonemployment in the short-run as well as in the long-run, but there has been few study on the school-to-work transition in Korea. This study focus on the nonemployment duration to first job after formal education and comparison of its pattern before and after the crisis. A proportional hazard model, considering job prenaration before graduation (21.4% of the sample), with the semi-parametric baseline hazard is applied to the sample from the Korean Labor and Income Panel Survey(1998~2000) and its Youth Supplemental survey(2000). Interview of the Survey is conducted, by the Korea Labor Institute, to the same 5,000 household and 13,738 individual sample, guaranteeing nationwide representativeness. The Supplemental Survey consists of 3,302 young individuals aged 15 to 29 at the time of survey and 1,615 of them who are not in school and provide appropriate information is used for the analysis. The empirical results show that there exists negative duration dependence at the first three or for months at the transition period and no duration dependence since a turning point of the baseline hazard rate and that unemployment rate reflecting labor demand conditions has a positive effect on exiting the nonemployment state, which is inconsistent with a theoretical conclusion. Estimation with samples separated by the date of graduation before and after the crisis shows that the effect of unemployment rate on the hazard was negative for the pre-crisis sample but positive for the post-crisis sample.

In this study, a standard vector data model was developed for interoperability of river-geospatial information and for verification purpose the applicability of the standard vector model was evaluated using a model to RIMGIS vector data at Changnyeong-Hapcheon & Gangjung-Goryeong irrigation watershed. The standards from ISO and OGC were analyzed and the river geospatial data model standard was established by applying the standards. The ERD was designed based on the analysis information on data characteristics and relationship. The verification of RIMGIS vector data included points, lines and polygon to develope GDM was carried out by comparing with the data by layer. This conducting comparison of basic spatial data and attribute data to each record and spatial information vertex. The error in the process of conversion was 0 %, indicating no problem with model. Our Geospatial Data Model presented in this study provides a new and consistent format for the storage and retrieval of river geospatial data from connected database. It is designed to facilitators integrated analysis of large data sets collected by multiple institutes.

Management systems for electronic library have been developed on the basis of Client/Server or ASP framework in domestic market for a long time. Therefore, both service provider and user suffer from their high cost and effort in management, maintenance, and repairing of software as well as hardware. Recently in addition, mobile devices like smartphone and tablet PC are frequently used as terminal devices to access computers through the Internet or other networks, sophisticatedly customized or personalized interface for n-screen service became more important issue these days. In this paper, we propose a new scheme of integrated management system for electronic library based on SaaS and Web Standard. We design and implement the proposed scheme applying Electronic Cabinet Guidelines for Web Standard and Universal Code System. Hosted application management style and software on demand style service models based on SaaS are basically applied to develop the management system. Moreover, a newly improved concept of duplication check algorithm in a hierarchical evaluation process is presented and a personalized interface based on web standard is applied to implement the system. Algorithms of duplication check for journal, volume/number, and paper are hierarchically presented with their logic flows. Total framework of our development obeys the standard feature of Electronic Cabinet Guidelines offered by Korea government so that we can accomplish standard of application software, quality improvement of total software, and reusability extension. Scope of our development includes core services of library automation system such as acquisition, list-up, loan-and-return, and their related services. We focus on interoperation compatibility between elementary sub-systems throughout complex network and structural features. Reanalyzing and standardizing each part of the system under the concept on the cloud of service, we construct an integrated development environment for generating, test, operation, and maintenance. Finally, performance analyses are performed about resource usability of server, memory amount used, and response time of server etc. As a result of measurements fulfilled over 5 times at different test points and using different data, the average response time is about 62.9 seconds for 100 clients, which takes about 0.629 seconds per client on the average. We can expect this result makes it possible to operate the system in real-time level proof. Resource usability and memory occupation are also good and moderate comparing to the conventional systems. As total verification tests, we present a simple proof to obey Electronic Cabinet Guidelines and a record of TTA authentication test for topics about SaaS maturity, performance, and application program features.

This dissertation is considerably studied Faction Genre which is embossed as a new image content, and it is figured out practical used works' possibilities for Korea film production's varieties. Faction, a neologism, which is combined by Fiction and Fact, is a boundary as limits. If authentic history is closed to a truth, it is a record history description method. Also, if unauthorized history is closed to a fake, it is a fictitious history description method. In addition, macro history and micro history are respectively connected to social criticism's matter and personal action, and these can make various analyses, depend on a boundary's limits and personal analysis. On the other hand, history film could be remembered to audience merely history film itself without existed history's fact. However, there are Faction Genre's Genre possibility and film's attraction which indirectness experience of historic fact could be experienced through film. For Faction Genre’s developing solution, there are three cognitive switches; audience's interpretation ability about history film through watching perception, linking between the past and the present for audience through communication with history, audience's considerable decision about history first or fiction first as film writer's interpretation. Above all, hopefully filmic pressure can be shown with historical true to audience. Therefore, it would be Korea Faction Genre's attraction and hope.

Mushrooms growing in the Wolchulsan National Park were surveyed from April to October 2018. As a result of this survey, 2 divisions, 9 classes, 24 orders, 71 families, 177 genera, and 407 species were found. Among them, 3 classes, 16 orders, 55 families, 150 genera, and 370 species belonged to Basidiomycota, while 6 classes, 8 orders, 16 families, 27 genera, and 37 species belonged to Ascomycota. The species richness was the highest in September at the altitudes between ~100 and 200 m. Among the investigated sites, the most diverse species occurred in the Gyeongpodae area. In this survey we found, Macrolepiota procera, Suillus bovinus, and Amanita pantherina, all of which have been known as climate-sensitive biological indicator species (CBIS). Based on the DNA sequence analyses, Craterellus parvogriseus was confirmed as a new record for Korea.

We investigated space-time patterns of Quaternary fault activity of the Yangsan fault zone using ESR ages in the Samnam-myeon region, Ulsan, Korea. Some of fault gouge zones consist of well-defined bands which added to the older gouge band, indicative of reactivation. During addition of new bands, the older gouge band was inactive, which represents the type I faulting mode. ESR analyses of each band of the gouge zone allow us to construct history of fault movement. The entire fault gouge zones were reactivated by type III faulting mode giving us ESR ages of the lastest reactivation. ESR dates show temporal clustering into active and inactive periods analogous to historic and paleoseismic fault activities. ESR ages and dates of fault movements indicate migration of fault activities along the Yangsan Fault Zone. Segments of the Quaternary faults in the study area are branched in the south of Sangcheon site. The earliest record of activity in segmented faults is recorded from the western segment to the northern segment. Before 750~850 ka ago, the fault gouge zone from the western segment to the northern segment were active. At 750~850 ka ago, the fault gouge zone from the eastern segment to the northern segment were active. During 630~660 ka and 480~540 ka only the northern segment was active. After 340 ka ago, the fault gouge zone from the western segment to the northern segment were active again.

The most important property for coming up to the global change and leading the knowledge-based future is human resources who has capacity to make a high value-added knowledge. For whom teaching knowledge and experiences related to the managing medical organization, it is very important and significant to make efforts to reflect educational goal, contents and teaching methods satisfying the new era's demands in the curriculum quickly. To develop a hospital management curriculum which is receptive to the change of medical industry and educational circumstances, analysing syllabuses of 19 departments of the year 2007 and surveying of professors, students and persons in charges of hospital administration are used. The syllabuses of 19 departments of 22 colleges were opened for this study. The medical record and other subjects take the most part of curriculums, while the number of subjects related to management or administrational practice are relatively small. The short of these subjects are obstacles to cultivate capacity and quality of students medical organizations look for. As the result of satisfaction measurement, hospital-management professors gave 3.41 points, students gave 3.29 points to the current curriculum and administrators who has been experienced to employ graduates majored in medical management gave 3.06 points.(5 points = full mark) Alternative ways are suggested to complement these problems as below: Strengthening and deepening study such subjects as strategy planning, management, marketing, managing medical disputes, quality improvement, PR, advertisement; changing informations and establishing cooperative programs between school and industry.

This study aims to explore the implications of the 2019 European Parliament elections. Existing studies show that European elections serve as secondary elections dominated by domestic issues. However, the 2019 European elections have highlighted pan-European issues such as the Brexit negotiations and the rise of far-right populism, with voter turnout also rising sharply to 50.62%, which is the highest record since the 2000s. There was also a significant change in the number of parliamentary seats held by each political group. First, the European People's Party(EPP) and the Progressive Alliance of Socialists and Democrats(S&D), which had hitherto led the European Parliament, failed to achieve a majority. Second, the number of seats won by Renew Europe, a new liberal-centrist group, was considerably high. Third, the far-right groups organized a full-fledged political force by rallying around the Identity and Democracy(ID) group. The rise of liberal-centrism can be explained as a reaction to the popularity of anti-European populism. Renew Europe's emphasis on open-market competition has created a different issue, especially since the center-left and center-right groups have stressed on the need for state intervention in employment, welfare, security and immigration control. Along with far-right populism, liberal centrism has also reshuffled Europe's political cleavage, and the conflict between 'liberalism' and 'protectionism' has become more evident in the European Parliament.

The term "conserved remains" refers to cultural remains that are preserved in accordance with the valuation of buried cultural properties when important remains are recognized in rescue excavations during construction work. South Korea's rapid economic growth and ensuing land development over the past few decades compelled a sharp increase in the number of rescue excavation cases, and, naturally, of conserved remains. Today, an increasingly large number of conserved remains have raised issues, including those concerning land expropriation as well as the management and utilization of such remains, but no clear solutions have been proposed. This study attempts to propose plans for improvement based mainly on the recognition of institutional issues rather than technical issues related to the conservation of cultural remains. This is because the identification and review of institutional deficiencies must be prioritized in order to efficiently manage conserved remains with limited resources and manpower. Among many possible proposals to demand improvement of conservation policies, one that must first be examined under the current system is the rapid transition, or review thereof, of "conserved remains" to "designated cultural properties." Unlike designated cultural properties, conserved remains are merely a temporary means of conservation, because they lack regulations for follow-ups subsequent to preliminary measures. Naturally, deferring the definition of relics as "conserved remains" for extended periods causes numerous problems. Measures to resolve such problems may include establishing a legal system to manage conserved remains at a level similar to designated cultural properties or seeking ways to improve management under the current system. This study focuses on areas where institutional improvement for conserved remains is possible by methods other than through the rapid transition to designated cultural properties and presents several proposals. Currently, conservation measures are divided into three categories: on-site conservation, relocation conservation, and record conservation. This study reclassifies these categories from three into four categories. On-site conservation includes only two categories: conserved remains and the newly-proposed soil-covered remains. Two remaining categories, the relocation conservation remains and the record conservation remains, are presented as classifications in which development projects are possible, and they are presented as alternative conservation types that contrast with on-site conservation. Unlike conserved remains, soil-covered conservation presented as a new category in which development projects are possible.
