In the current discourse landscape where the opinions of stakeholders on game self-regulation are opposed, this study was conducted for the purpose of finding improvements by examining the effects of media reports on self-regulatory policies or perceptions. From July 2018 to June 2020, all articles reported for about two years were selected and the final 325 data were used for the study. For detailed frame analysis, the first and second frames were derived inductively. In the results of the study, it was analyzed that the in-depth understanding of the topic of self-regulation, the use of objective data, and the diversity of information sources were insufficient throughout the report.

This paper is to study the development of three dimensional Digital Surface Model (DSM) using photogrammetry technique based on self-developed Drone (Unmanned Aerial Vehicle (UAV)). To develop DSM, we selected a study area in Jeju island and took 24 pictures from the drone. The three dimensional coordinates of the photos were made by Differential Global Positioning System (DGPS) surveying with 10 ground control points (GCP). From the calculated three dimensional coordinates, we produced orthographic image and DSM. The accuracy of DSM was calculated using three GCPs. The average accuracy of X and Y was from 8.8 to 14.7 cm, and the accuracy of Z was 0.8 to 12.4 cm. The accuracy was less than the reference accuracy of 1/1,000 digital map provided by National Geographic Information Institute (NGII). From the results, we found that the self-developed drone and the photogrammetry technique are a useful tool to make DSM and digital map of Jeju.

This study : An analysis of position accuracy of topography according to using LiDAR data, aerial photo and digital map for a study area was conducted. The study area was selected in Hadan area, Sahagu, Busan aerial LiDAR data and aerial photo in the scales of 1:20,000, which are high tech surveying ways were used. The final digital orthoimage according to orientation process for each image and image resampling was producted. Using it, a checkpoint was chosen, information about the checkpoints selected was extracted, a coordinate of Horizontal Position through the screen digitizing was also extracted. Both the coordinates of LiDAR data and aerial photo using digital map in the scales of 1:20,000 announced to the public from NGII(National Geographic Information Institute) were gradually compared and analyzed. Based on the digital map, as a result of being both compared and analyzed, it has shown to us that horizontal position of aerial photo is more accurate than that of aerial LiDAR surveying (RMSE-building x:24cm, y:26cm).

In the past few years, data leakage of information assets has become a prominent social issue. According to the National Industrial Security Center in South Korea, 71 percent who suffer from technology leakage are small and medium sized enterprises. Hence, establishment and operation of ISMS (Information Security Management System) for small and medium sized enterprises become an important issue. Since it is not easy to obtain ISMS certification for a small or medium sized enterprise by itself, consultation with an expert firm in information security is necessary before the security implementation. However, how to select a proper security consulting company for a small or medium sized firm has not been studied yet. In this study, we analyze empirically the selection factors of ISMS certification consulting company for a small or medium sized firm through exploratory factor analysis (EFA). Our study identified the following four important factors in selecting a security consulting company: expertise of the staffs and human resource management proficiency, market leading capability, competence to make progress during the consultation, and the performance and the size of the physical assets and human resources.

정보화의 발전에 비례하여 정보보호의 중요성도 높아지고 있다. 최근까지 정보보호에 대한 관심과 주요 연구의 흐름은 기술적인 보호조치(예: 암호화, 접근제어, 방화벽 등)와 관리적 관점의 행동연구였다. 최근에 들어서야 국내외적으로 정보보호 투자효과에 대한 연구가 활성화되기 시작했다. 정보보호 투자효과에 대한 계량적 산정이 필요한 이유는 정보보호의 중요성을 정확하게 인식할 수 있어 적정규모의 예산을 책정하고 효율적으로 예산을 투입할 수 있는 기초를 마련할 수 있기 때문이다. 정보보호 투자효과를 측정하기 위한 선행연구로 보안사고의 피해규모를 산정하는 연구가 필수적이다. 보안사고의 피해규모는 가시적 손실(피해복구, 생산성 저하, 손해배상 등)과, 비가시적 손실(고객 충성도 저하, 회사의 브랜드 이미지 하락 등) 규모의 합으로 구성된다. 그 동안 가시적 손실규모 측정에 관한 연구는 상대적으로 많았으나, 비가시적 손실규모 측정에 관한 연구는 상대적으로 미흡하였던 것이 사실이다. 이는 현실적으로 비가시적 손실규모를 측정할 수 있는 접근방법을 고안해내는 것이 어려웠기 때문이다. 이로 인해 막연히 비가시적 손실규모가 가시적 손실규모에 비해 대단히 클 것이라고 짐작해 올 수 밖에 없었다. 본 논문에서는 보안사고의 비가시적 손실규모를 측정하기 위해 대규모 개인정보 보안 사고가 발생한 기업의 매출액 증가율을 경쟁기업과 분석하는 연구방법을 제안한다. 매출액은 영업이익 및 순이익과는 달리 회사 내부적인 회계방침에 의해 규모의 조절이 불가능한 재무요소이면서 회사가 고객 충성도 저하와 회사의 브랜드 이미지 하락으로 인해 받게 되는 영향을 가장 정확하게 반영하는 재무요소이기도 하다. 연구방법에 따라 2008년 대규모 개인정보 보안사고가 발생한 국내기업을 선정하고 그 경쟁사와 매출액 변화추이를 비교 분석하였다. 분석결과 보안사고가 발생한 기업의 평균 매출액 증가율이 경쟁사 평균 매출액 증가율 보다 0.0225% 높다는 사실을 발견했다. 이 결과는 국내의 보안 사고가 기업 가치에 미치는 비가시적 영향이 거의 없거나 또는 발생하더라도 그 영향력이 미미하여 가격정책 및 광고 홍보를 통해 충분히 극복할 수 있다는 점을 대변한다. 본 논문의 결과는 역설적으로 국내 보안사고의 피해규모를 측정하는데 있어 가시적 손실규모의 정확한 측정이 무엇보다 중요함을 의미한다.

The Brightness, color and texture included in a multispectral satellite data are used as important factors to analyze and to apply the image data for a proper use. One of the most significant process in the satellite data analysis using texture or color information is to extract features effectively expressing the information of original image. It was described in this paper that six features were introduced to extract useful features from the analysis of the satellite data, and also a classification network using the back-propagation neural network was constructed to evaluate the classification ability of each vector feature in SPOT imagery. The vector features were adopted from the training set selection for the interesting region, and applied to the classification process. The classification results showed that each vector feature contained many merits and demerits depending on each vector's characteristics, and each vector had compatible classification ability. Therefore, it is expected that the color and texture features are effectively used not only in the classification process of satellite imagery, but in various image classification and application fields.

한강의 제1지류인 홍제천 수계에 속하는 지방2급 하천인 불광천 유역을 연구대상지로 선정하여 기후변화에 따른 유출량 영향성 분석을 수행하였다. 연구대상지인 불광천은 서울특별시의 서북쪽에 위치하여 $21.72km^2$의 유역면적과 9.83km의 유로연장을 갖고 행정구역상 은평구, 마포구, 서대문구에 걸쳐있다. 본 연구에서는 불광천 유역을 503개의 소유역으로 분할하였으며, 유역의 하수관망은 976개의 노드와 989개의 링크를 사용하여 XP-SWMM 모형으로 구축하였다. 또한 국토지리정보원에서 제공하는 1:5000축척의 수치지도를 DTM으로 변환하여 하수관에서 월류된 이후의 2차원 흐름분석을 위한 지형자료로 활용하였다. 기후변화를 고려한 유출량을 분석하기 위해 S0(1961년~2016년)인 1개의 과거기간과 S1(2017년~2046년), S2(2047년~2076년), S3(2077년~2100년)인 3개의 미래기간을 설정하여 총 4개의 시나리오를 구성하였다. 과거기간인 S0는 강우관측소에서 계측된 자료를 사용하여 빈도별 확률강우량을 구하였으며, 미래기간인 S1, S2, S3는 기상청에서 제공하는 기후변화 시나리오인 RCP 4.5의 강우자료를 사용하여 확률강우량을 산출하였다. 빈도별 확률강우량은 S0기간의 강우자료와 가장 유사한 Gumbel 모형을 사용하였으며, 도출된 확률강우량은 치수에 가장 보수적인 Huff의 4분위로 강우를 분포시켜 유출모형에 적용하였다. 976개의 노드 중 불광천 유역의 주요 76개 지점을 선정하여 유역면적에 따른 기후변화의 영향성을 분석하였다. 그 결과 유역면적과 재현기간이 작을수록 최대 유출량은 큰 변동성을 보이는 것으로 나타났으며, 과거기간인 S0 대비 미래기간인 S1, S2, S3의 최대 유출량 비율은 유역면적 100ha를 기준으로 100ha 미만은 80%~200%의 변동성을 100ha이상에서는 120%에 수렴하는 양상을 보이는 것으로 확인되었다.

Public libraries and the Library & Information Sciences departments at Korean universities are increasingly interested in the application of a variety of bibliotherapy methods. Bibliotherapy serves as a therapy to understand a client and participants basic material sources and the effects of that particular treatment (necessary for program verification of psychological tools utilized). Its design is based both on literature selection and employed activities tools. Currently, bibliotherapy has been used mainly as a method to understand and diagnose a client and participants using simple and uniform questions. The development of appropriate and, possibly, additional assessment tools and report forms required for bibliotherapy evaluations in this study will be applied to actual case scenarios to determine the validity of this program and/or tools.

Ten Web sites from educational policy authorities, educational research institutions, professional educational, and national libraries that provide educational policy information services are investigated using content analysis method. They are analyzed using various types of information sources, classification schemes, and functions of information retrieval. Standardization of classification scheme of educational policy information, standardization of meta data items, improvement of retrieval systems, provision of personalized information services to educational policy authorities, operation of specialized policy information centers, and cooperation among professional institutions are suggested. A model of a specialized educational policy information center is proposed.
