Today, MMS (Mobile Mapping System) uses the strengths of individual sensor technologies on a variety of platforms to increase the efficiency of geospatial data collection. In this paper, we analyzed the market size and technology trend of mobile mapping market in Korea and abroad, and analyzed frequency, trend, and characteristics of MMS related patents. The results of the analysis are as follows: First, it is expected that the domestic and overseas mobile mapping market will continue to grow in the future, and MMS-related technologies and applications are rapidly developing. Active research and development investment is required to preoccupy future market through technology development and patent competition. Second, the frequency of filing domestic patents is highly correlated with the results of national R&D, and industrial patent applications are highly related to national projects. It is analyzed as the result of introduction of preemptive technologies and research and development of companies for preemption in related industry rather than market development. Lastly, in Korean geospatial information industry survey, It is necessary to maintain the data so that it can be compared with the data of foreign institutions. In particular, statistical data that can grasp the market size in terms of geospatial information utilization and technical aspects are desperately needed.

The configuration analysis for the image appeared in the storyboard as the 1st stage to change the scenario to the image expressed the visual phenomenon image starting from the literalism. The simultaneity of description on the interpretative level of the narrative description may describe various information multiple simultaneously, the relationship has been presented as a lot of these information has been weaved as one episode. The incident time of narrative description as the scene described mainly objectively and illustratively has been used usefully to present the accurate information for characters or incidents. The time series of narrative description appeared as one episode by expressing various spaces or images under the continuity of flow according to the time. The collision image seen from the angle of internal ignition played a role to create the meaning colliding into each other or interconnecting symbolic effects appeared as respectively fragmented image, the continuity of space played a role of expressing the different symbol when the image of completely different space is connected to one context, the continuity of time as well makes a different symbolism by interpreting symbols appeared as each images under the flow of time. These results show that the narrative description may be expressed in accordance with the narrative structure from the viewpoints of narrative description, but the internal ignition may be interpreted through the cultural and periodical background widely known in those years based on the experience and information capability the audiences are keeping not by any descriptive structure. Images appeared in the internal ignition appeared by colliding into each other or amplifying mutually no related scenes and revealing the overall symbolism by reinterpreting again.

Recently, there have been various problems aroused on the domestic infrastructures as the domestic cities become old. Accordingly, the national concerns grow on the urban railway and the related structures, which brings the national interests are brought on the research on the maintenance and rehabilitation of the old infrastructures. The underground structure of urban railway are checked with the strain gages or fiber brag grating (FBG) sensors on the railway. However, these methods are known to have resolution limitations on the investigations of the specified abnormal section. Therefore, the applicability of the Brillouin Optical Correlation Domain Analysis (BOCDA) based distributed fiber optic sensor system on the railway was evaluated in this study. The constructed BOCDA fiber optic sensor system shows high resolution of 10, 20, 50, 100 cm and capability of continuous monitoring on overall or specified section within 2 km range. The applicability evaluation was performed on the 250 m distribution of fiber optic sensors abandoned railway for continuous monitoring. The applicability of the system on the specified area was evaluated with wheel load testing. As a result, data loss tends to increase with the reduction of spatial resolution from 1.0 m to 0.1 m. Even though the measuring speed is reduced with lower spatial resolution, data accuracy increases on the location and deformation. The system can be applicable to various structures if the proper distribution method is invented later.

The goal of this investigation is to examine the matter as to how various cyberpolitical activities such as on-line civic participation, cyber parties, development and movement of civil society networks are appeared in cyberspace; and how political activities in cyberspace are associated with offline environment. This research was based on in-depth and open-ended interviews centering around 20s (32 interviewees) and the major results are as in the following. First, in terms of on-line civic participation, searching political issues occur in places, where internet users can access information easily relatively, and creating or reconstructing political information is identified in places giving stability or affinity to the public society. Second, even though each party's homepage for the channel of cyber parties has enough capacity as bridgespace, which takes charge of supporting f lows of people, goods, capital, and ideas, most of them don't play a role to establish virtual or real networks. Exceptively, cyber parties contribute to make temporalized places, where nobody takes the responsibility, somewhat. Third, the development and movement of civil society networks is divided into several segments according to political interests and tendency in online; furthermore, such a cyberpolitical activity influences human networks and the decision of major places for political activities in offline.

The record industry, which consists of the cultural industries, has been deeply interrelated with the innovations of the science and the technologies. In Korea, the record industry has been developed dramatically since the late 1980s, and thus it has formed a huge business, and has also brought a lot of accompanying economical effects. The record industry is constituted with four circulation steps such as producing, manufacturing, wholesaling and retailing, which follow the different locational orients, respectively. The purpose oi this study is to investigate the locational characteristics of each step. Because of the shortage of the data, this study based on the direct data from field studies, interviews, and surveys, as well as the existing document data. The results of this research are summarized as following: the record industry shows strong concentrations in Seoul and the surrounding areas. It also shows the spatial linkage with other industries that are necessary for the production, advertisement, and sales of records. The locations of the record producers are affected by the location of broadcasting stations. Therefore, they are concentrate in Kangnam and Yeouido, where many broadcasting stations are located.

The communication environment made by digital technologies has made it possible to exchange information and deliver messages fast and easily among people of various classes in virtual space beyond time and space. Net-generation, who is accustomed to this virtual space, couldn't be satisfied with the linear text-oriented language any more, and began to make signs by use of computers in order to differentiate itself from others and to express its desires. Among the signs, emoticon created by joint of popular culture and digital communication centering around young generation is a new visual sign and emotional sign that can deliver a sender's feelings contained in a message. This paper has studied social phenomena, their relationships with emoticon and background of its creation through documentary review of media development, changes in the communication environment and popular culture. Furthermore, it has analyzed the meaningful action and roles of emoticon as a sign in terms of semiotics and also, studied a possibility of using emoticon as a new emotional sign. The study results say that emoticon can play the roles of a non-linguistic sign just like general signs that make mutual exchange through meaningful action, and also that it can be used to effectively deliver messages not only in virtual space, but also in advertising, posters, magazines and CI. However, emoticon is better at emotional expressions yet than other textual signs or visual signs, but in order to position itself as a universal and popular sign, emotional expressions should be clear, any difference in understanding messages should be removed, and message delivery should be more efficient.

호우가 홍수에 미치는 영향의 분석은 수문현상을 이해하고 수공구조물을 설계하는데 반드시 필요한 절차이다. 호우가 홍수에 미치는 영향을 분석하기 위해서 독립된 소유역부터 비독립된 대유역까지 홍수량을 계산하고 그 상관성을 이해해야 하지만 상류쪽의 소유역의 경우 관측자료의 부재가 빈번하여 이러한 전반적인 분석이 쉽지 않다. 그리고 소유역과 대유역의 홍수특성을 연관지어 분석하기 위해서는 비교가능한 홍수특성을 추출해야 하며 이러한 일관된 잣대를 사용한 홍수분석은 중요하다. 본 연구에서는 소유역의 자료부재를 보완하기 위해 자료공간확장 방법을 제안하고 이를 통하여 안동댐 유역내 총 50개 지점의 홍수 시계열자료를 생성하였다. 자료공간확장 방법으로써, 안동댐유역의 1989년부터 2009년까지의 자료의 질이 좋은 20개의 사상을 추출하였고 안동댐유역 내에 위치한 안동댐, 도산, 소천의 수위관측지점의 관측유량자료에 대해 분포형 모형인 GRM 모형의 매개변수를 시행착오법으로 동시에 보정하여 한 개셋의 최적 매개변수를 추정하였다. 이때 모의결과를 평가하기 위하여 Nash-Sutcliffe (NS) 계수를 사용하였으며 20갯 사상의 세군데 관측수위지점에 대해서 모의결과가 전반적으로 0.5 NS 계수 이상으로써 만족할 만한 결과를 얻었다. 이 추정된 매개변수는 47개의 추가적인 관심지점의 유출모의에 사용되었으며 이렇게 모의된 유출시계열 자료는 관측시계열 자료로 가정하여 사용하였다. 이렇게 공간확장되어 생성된 시계열 자료는 이동평균방법을 사용하여 홍수강도-지속시간 곡선으로 변환되었고 50개 유역의 평균강우량 시계열 자료 또한 같은 밥법을 사용하여 강우강도-지속시간 곡선으로 변환되었다. 50개 유역의 비교가능한 일관된 홍수특성을 추출하기 위해 비유량법의 유출계수를 계산하였다. 유출계수를 계산하기 위해 유역별 도달시간을 계산하였으며 이 도달시간에 해당하는 강우강도를 추출하였다. 그리고 유역별 첨두 홍수강도를 유역별 도달시간에 해당하는 강우강도로 나눠줌으로써 유역별 유출계수를 계산하였고 이 유출계수를 유역면적에 대해 도시함으로써 그 경향을 조사하였다. 조사 결과 유역면적이 $100km^2$ 이상으로써 상류에서 하류방향으로 유역이 중첩되면서 증가하는 비독립적인 유역들의 경우 유역면적이 증가함에 따라 유출계수가 작아지거나 커지는 어떠한 경향을 보였다. 하지만 유역면적이 $100km^2$ 이하로써 독립적인 소유역의 경우 유역면적이 증가함에 따라 유출계수는 무작위로 분포되었다. 이것은 비독립적인 유역의 경우에는 호우가 홍수에 어떠한 일관된 영향을 미치나 각각 독립된 소유역의 경우에는 일관된 영향을 미치지 않음으로써 지역화방법에 의한 독립된 인근 미계측유역의 유출추정은 그 신뢰성이 높지 않다는 것을 의미한다.

The field of geospatial information is rapidly changing due to the development of sensor and data processing technology that can acquire location information. And demand is increasing in various related industries and social activities. The construction and utilization of three dimensional geospatial information that is easy to understand and easy to understand can be an essential element to improve the quality and reliability of related services. In recent years, 3D laser scanners are widely used as 3D geospatial information construction technology. However, 3D laser scanners may cause shadow areas where data acquisition is not possible when objects are large in size or complex in shape. In this study, 3D model of an object has been created by acquiring oblique images using an unmanned aerial vehicle and processing the data. The study area was selected, oblique images were acquired using an unmanned aerial vehicle, and point cloud type 3D model with 0.02 m spacing was created through data processing. The accuracy of the 3D model was 0.19m and the average was 0.11m. In the future, if accuracy is evaluated according to shooting and data processing methods, and 3D model construction and accuracy evaluation and analysis according to camera types are performed, the accuracy of the 3D model will be improved. In the point cloud type 3D model, Cross section generation, drawing of objects, and so on, it is possible to improve work efficiency of spatial information service and related work.

Korea, which became an aging society in 2000, has made transition to an aged society more quickly than expected since late 2017 after 17 years. Despite this trend, the awareness towards elderly housing facilities has not yet been raised across in society. The primary reason is that use of elderly housing facilities has not been promoted due to lack of understanding about the construction and management of the facilities. The housing of the elderly should be considered in terms of not only residential space but also the issues of medical care and continuous care. Therefore, the trend of elderly housing is pursuing the Continuing Care Retirement Community. Thus, this study analyzed the policies of existing elderly housing facilities and existing elderly housing through comparison with policies and housing of foreign countries. Based on the results, the the government intends to present characteristics and direction of suitable housing design of senior citizens' housing facilities through maintenance of UNIT, securing convergence through changes in the use of facilities, and realising the cost of operation, and studying social welfare measures to cope with the increasing number of elderly residents.

Action games exhibit all the specific constellation of masochism, such as disavowal, suspense, waiting, fetishism, and fantasy. These characteristics of action games can be analyzed with respect to masochism. This study conducted an analysis excluding sadism as much as possible, as sadism is a result of etiological misconception as opposed to masochism. However, comparative analysis is included in the study so that action games are not seen as demonstrating sadism. Games create a space for virtual interaction for main agents by connecting gamer-existence and game-character in the framework of a contract. The interaction of visual tactility within this space creates a system of difference in pleasure. Masochism enables one to attain pleasure in a world created himself or herself using fetishism in contractual relationships such as the ones exhibited in games. This shows that action games and masochism are mutually related. This paper analyzed the ontology of action games using actual examples of action games. The paper concluded that action games lead to the fulfillment of masochistic pleasure.
