The Korean government strives to transform the society from one that stresses academic and qualification to one that stresses individual competencies. National Competency Standards(NCS) has been adopted to this end. However, NCS classifies cadastre into a group with survey and spatial information collection. Such classification limits cadastre to encompass cadastral administration, cadastral survey, geospatial survey, etc. This study reviews current status and implications of NCS, and proposes few solutions: improvement of classification system, introduction of cadastral industry cooperation model, curriculum development based on competency level, unification between NCS developer and learning module writing group, etc.

Twenty years ago, the American Journal of Epidemiology published David Sackett's brief description of. clinical epidemiology and its practitioners [1]. This commentary was a useful focal point for an emerging discipline. By 1983, with clinical epidemiology already thriving in many academic medical centres, Walter Holland called into question both the term, 'clinical epidemiology', and the nature of the discipline [2]. More recently, clinical epidemiology has drawn strong criticism from John Last, a noted academician whose contributions include the editorship of the Maxcy-Rosenau Textbook of Public Health. Writing in the Journal of Public Health Policy in 1988 [3], Last referred to the 'uncritical enthusiasm' for clinical epidemiology in medical schools as 'a danger to health', and staked. a claim to the term 'epidemiology' as appropriate only to the description of what classical or population epidemiologists do. Faced with such views, practitioners and proponents of clinical epidemiology can respond in three ways. They can ignore the criticism, and go on about their business. They can reaffirm their differences and resort to defensive rhetoric. Or, the critique can become an opportunity for reflection about the nature of clinical epidemiology and its relations with sister disciplines in modem medical schools. The latter course is followed here by four physicians who-despite diverse backgrounds and interests-all consider their work to be in the field of clinical epidemiology.

Holographic Data Storage System, one of the next generation data storage devices, is a 2-dimensional page oriented memory system using volume holograms in writing and retrieving process. Recently photopolymer with disc type substrate was selected as a media for the Holographic Data Storage System. The disc tilt occurs when the media rotates and the external disturbance applies. The disc tilt causes the change of the angle between the reference beam and the media, the data cannot be retrieved with the right angle or other data page is retrieved. The tilt is generated in a 2-axis direction (tangential, radial). The tangential tilt direction is the same with the multiplexing plane, while the radial tilt direction is a perpendicular to the multiplexing plane. In this research we propose 2-axis tilt angle servo system. The tilt errors are measured by using external photo detector and the additional red laser. Then the tangential direction tilt is compensated by using the galvano mirror. Also the radial direction tilt is compensated by the rotating prism between the relay lens in the reference field. Finally we confirm the compensation results through the Signal to Noise Ratio(SNR) and Bit Error Rate(BER).

Micro-conductive patterns were microfabricated on an insulating substrate ($SiO_2$) surface by a selective electroless nickel plating process in order to investigate the formation of seed layers. To fabricate micro-conductive patterns, a thin layer of metal (Cu.Cr) was deposited in the desired micropattern using laser-induced forward transfer (LIFT). and above this layer, a second layer was plated by selective electroless plating. The LIFT process. which was carried out in multi-scan mode, was used to fabricate micro-conductive patterns via electroless nickel plating. This method helps to improve the deposition process for forming seed patterns on the insulating substrate surface and the electrical conductivity of the resulting patterns. This study analyzes the effect of seed pattern formation by LIFT and key parameters in electroless nickel plating during micro-conductive pattern fabrication. The effects of the process variables on the cross-sectional shape and surface quality of the deposited patterns are examined using field emission scanning electron microscopy (FE-SEM) and an optical microscope.

In spite of importance of the experience education in Korean classic education, it has not made study in this field. Especially, is famous for typical Korean classic as a travel literature, but it was considered as a writing model or a novel. This study focuses on as the travel literature. For the experience education, it must be considered that literature appreciation is a core. So the experience education contents will contain what is selected, how to present, and how to teach. The resource of the experience education have to arouse educational meaning and interest in the classic literature. Concerning , there are two type of experience. First, the writer's experience. The writer, Yonam experienced a extra ordinary events. He wrote this event through other's points. This showed other's situation so it could make understand other's feeling and thought. Second, the reader's experience. A modern reader considers Korean classic as something difficult and strange. but if reader would have the point of view of others, he could understand more easily. Further, it will be expected that the reader can reflect on own's situation and conduct.

The purpose of this corpus-based study was to find 4-word lexical bundles in computer science research articles. As the demand for research articles (RAs) for international publication increases, the need for acquiring field-specific writing conventions for this academic genre has become a burning issue. Particularly, one area of burgeoning interest in the examination of rhetorical structures and linguistic features of RAs is the use of lexical bundles, the indispensable building blocks that make up an academic discourse. To illustrate, different academic discourses rely on distinctive repertoires of lexical bundles. Because lexical bundles are often acquired as a whole, the recurring multi-word sequences can be retrieved automatically to make written discourse more fluent and natural. Therefore, the proper use of rhetorical devices specific to a particular discipline can be a vital indicator of success within the discourse communities. Hence, to identify linguistic features that make up specific registers, this corpus-based study examines the types and usage frequency of lexical bundles in the discipline of CS, one of the most in-demand fields world over. Given that lexical bundles are empirically-derived formulaic multi-word units, identifying core lexical bundles used in RAs, they may provide insights into the specificity of particular CS text types. This will in turn provide empirical evidence of register specificity and technicality within the academic discourse of computer science. As in the results, pedagogical implications and suggestions for future research are discussed.

The advent of the AI(: Artificial Intelligence) has applied to many industrial and general applications have havingact on our lives these days. Various types of machine learning methods are supported in this field. The supervised learning method of the machine learning has features and targets as an input in the learning process. There are many supervised learning methods as well and their performance varies depends on the characteristics and states of the big data type as an input data. Therefore, in this paper, in order to compare the performance of the various supervised learning method with a specific big data set, the supervised learning methods supported in the Tensorflow and the Sckit-Learn are simulated and analyzed in the Jupyter Notebook environment with python.

Recently, interest in the precast concrete (PC) construction method has been increasing. The PC construction process consists of i) design, ii) production, iii) transportation, and iv) installation. A PC field manager at the site submits a shipment request form to the factory one to three days before the installation of the PC component. Numerous matters should be considered in writing a shipment request form. Incorrect shipment request forms may cause standby resources, waste of resources, premature work conclusion, or excessive work. These issues can lead to an increase in construction costs, replanning of PC component installation, or rework. In order to prevent such problems, PC component installation should be simulated based on the shipment request form. Accordingly, this study aims to identify factors influencing the operability of shipment request forms for PC construction. To this end, this study derived factors influencing i) initiation of the activity, ii) addition or deletion of activities, and iii) an increase or decrease in the activity execution time. As a result, this study identified flow, the features of PC components, condition of PC components, unloading location, installation location, input equipment and labor, number of anchors, number of supports, weather, strike, and accident. Further studies should verify the factors derived in this study based on focus group interviews.

In this study, we introduce a system for real-time monitoring of field conditions within an industrial complex using a 5G network UAV (: Unmanned Aerial Vehicle). When a monitoring event occurs in a sensor mounted on a UAV (detection of fire, harmful gas, or industrial disaster type human accident), key information from the sensor is transmitted to the UAS (: Unmanned Aerial System) application server. As a result of this information transmission and processing, managers or operators of the Industrial Complex Corporation were able to secure legal basis data for fatal accidents, fires, and detection of harmful gases at sites within the Industrial Complex Corporation through trigger processing for each accident risk situation.

Most academic journals in the world today typically require submission of journal article titles in English. However, most authors and reviewers are insensitive to the fact that cultural differences at a national level exist in writing titles. In this paper, journal article titles that have been published in the United States and Korea were compared in order to find cross-national cultural characteristics in these titles. To conduct this study, sample titles in the field of social sciences were obtained from two bibliographic databases-Scopus and RISS. A frequency count on number of variables was used: length of title, types of titles and n-gram phrases. In addition, a variety of similarities and differences found from this study including the type of words and phrases that Korean authors tend to favor in journal articles. The results showed that there is a considerable amount of cultural related variability in the construction of journal article titles. This study suggests that cross national characteristics of journal article titles should be emphasized in the future.
