Although the internet has gained many conveniences and benefits, it is causing economic and social damage to users due to intelligent malware. Most of the signature-based anti-virus programs are used to detect and defend this, but it is insufficient to prevent malware variants becoming more intelligent. Therefore, we proposes a model that detects and defends the intelligent malware that is pouring out in the paper. The proposed model learns by imaging the characteristics of malware based on deeplearning, and detects newly detected malware variants using the learned model. It was shown that the proposed model detects not only the existing malware but also most of the variants that transform the existing malware.

Prediction of vehicle traffic volume is very important in planning municipal administration. It may help promote social and economic interests and also prevent traffic congestion costs. Traffic volume as a time-varying trajectory is considered as functional data. In this paper we study three functional regression models that can be used to predict an unseen trajectory of traffic volume based on already observed trajectories. We apply the methods to highway tollgate traffic volume data collected at some tollgates in Seoul, Chuncheon and Gangneung. We compare the prediction errors of the three models to find the best one for each of the three tollgate traffic volumes.

최근 20년간 마케팅을 비롯하여 사회과학 전반에 걸쳐 기업이론에 관하여 새로운 패러다임으로 각광을 받아온 신제도학파 접근방법은 이익극대화를 기업의 중심적 행동으로 가정하고 있는 신고전학파의 맹점을 극복하여 조직문제를 포괄적으로 다룰 수 있음을 보여주고 있다. 이 이론은 한정된 합리성, 기회주의, 자산 특수성, 지배구조, 신뢰 및 협동 등의 핵심적 개념들이 동태적 환경 하에서 활동하고 있는 기업의 경제적 행동을 분석하고 이해하는데 크게 기여하였음이 입증되고 있다. 이것은 다수의 실증적 문헌들에서 엿볼 수 있다. 그러나 신제도학파의 이론적 틀은 두 가지 면에서 주요 결점을 안고 있다. 그 하나는 이론의 정당성을 입증하기 위한 실증적 연구결과물을 무수하게 찾아볼 수 있으나, 대부분이 연구의 타당성이 결여되어 있다는 점이고, 또 하나의 결정적 결함은 신고전학파와 마찬가지로 비교정태적 접근방법을 택함으로써 역사적 관점이 도외시되고 기업의 전략개발과 구조적 변동을 이해하는데 필수적인 조직과 기술간의 동태적 상호작용의 중요성을 간과하고 있다는 점이다. 이에 따라 본고에서는 국제교역 이론가들이 제시한 기업 특유의 경쟁우위에 관한 착상과 그러한 우위가 기업 내외의 네트워크 형성을 포함하여 결집된 조직역량에서 도출된다는 견해를 거래비용이론에 접목시킴으로써 기업의 성격과 그 성장방식을 보다 설득력있게 이해할 수 있으리라는 관점을 제시하려 하였다. 이와 같이 거래비용이론과 진화론을 결합하면 신제도학파 기업이론의 결점이 보완되고 이론의 발전이 한 단계 진일보할 것으로 기대된다. 특히 마케팅 연구자들이 거래비용이론의 경우와 마찬가지로 본고에서 제시한 통합이론에 대해서도 실증적 연구를 행하면 이론개발에 크게 기여할 것으로 생각된다.

Recently the entertainment and sports/advertisement industry have developed rapidly, and the name or identities of celebrities such as entertainers or athletics for the advertisement so that following troubles are occurred continually. Some celebrities actually started a suit for there right of publicity was violated, and won the case. Meanwhile, the right of publicity has become a growing issue in the society. In the States, the right of publicity which controls using one's identity for commercial use, and it is recognized as a right of property separated from the right of privacy. But in Germany, the right of publicity is protected as a human right. On the other hand, in Korea, there is an argument that the mental human right and the right of publicity which has property-characteristic are not separated clearly, and also the attitude of precedent toward the right of publicity is not unified. Especially in Korea, where it is taking the written laws principally, it is not easy to recognize the right of publicity which is a monopoly and exclusion without basis such as any actual laws such as regulation of agreement or any conventional laws. Therefore, as the right protection of celebrities is becoming the social state and there is an agreement with the constituents of the society, now Korea shall progress legislation about the right of publicity, and prepare a legal basis which regulates the remedies for the realization condition, alienation, inheritance, objectives, duration and violation of the right of publicity.

This study examines how national newspapers interpret, evaluate and report the Korean grand canal and rebuilding four major rivers through the news writings. For this research, ChosunIlbo, the Hankyoreh Shinmun and HankukIlbo are selected. A total of 961 news writings are analyzed by using the concept of news frame designed by Gamson(1993). As a result, the findings are as follows: First, the most frequently reported news frame for ChosunIlbo is economic consequence; the Hankyoreh for ecological environment, and HankukIlbo for authoritative political execution by the administrative. Second, the most frequently interviewed group through all of the papers is the administrative and the ruling Grand National Party, the main body of rebuilding the Korean grand canal. On the country, voices of environmental protection groups, non-profit civic organizations and the ordinary people are reported rarely. Third, the ratio of authoritative political execution by the administrative and economic consequence are very high. Finally, in terms of the framing activity by the interviewed groups in the newspapers, ChosunIlb reports 'Outcome' the most frequently, the Hankyoreh does 'Loss-gain' & 'Process' and HankukIlbo 'Process' & 'Substantive'. Thus it concluded that ChosunIlbo does not play a role as a social mediator for the social disputes. However, the Hankyoreh and HankukIlbo try to represent environmental and civic organizations fairly.

점차 증가하는 도로상에서의 승용차의 비율은 전체 도로교통여건의 악화뿐만이 아니라 국가경제에 있어서도 물류비용의 증가를 가져와 국제경쟁력에서의 약화 및 수출조건의 악화의 원인이 되고 있다. 이러한 물류비용의 감소를 위하여 고속도로에 있어서의 화물전용차선의 설치가 논의되고 있으나 화물전용차선의 설치에 따른 사회 각 분야의 경제적 이익과 불이익을 정확히 산출하여 새로운 교통시설 공급의 효과를 정확하게 파악하지 못한 채로 정책적인 대안의 일환으로 논의되고 있으며, 기존의 고속도로의 교통혼잡비용의 연구에 있어서도 화물통행의 시간가치를 화물차의 운전자의 시간가치로 분석하여 개별 화물통행의 시간가치를 간과하여 분석하고 있는 실정이다. 본 연구는 이러한 배경하에 화물통행의 시간적 가치를 측정하는 방안을 정립하고 고속도로에 있어서의 화물전용차선의 설치가 기존의 교통체계에 미치는 효과를 정확히 분석하고 시설공급에 따른 경제적 편익을 체계적으로 분석하여 이에 따른 화물전용차선 설치의 평가기준을 마련하는데 그 목적이 있다. 본 연구를 통하여 나타난 결과는 다음과 같다. -첫째, 연구대상구간 전체를 기준으로 볼때에 모든 대안에서 화물전용차선의 설치시는 화물전용차선의 미설치시보다 오히려 사회전체의 편익이 감소하는 것으로 나타났다. -둘째, 구간별로 구분하여 분석하였을 경우에는 대안3의 경우 일부구간에서 화물전용차선에 설치에 따른 편익이 발생하는 것으로 분석되었는 바, 상행선의 경우 17:00∼21:00시에 신갈∼오산구간에서 실시하는 것이 가장 높은 편익을 발생하며, 하행선의 경우 06:00∼10:00시에 신갈∼오산구간에서 실시하는 것이 가장 편익이 높게 분석되었다. -셋째, 화물의 통행가치의 증가 및 화물교통량의 증가를 예상하여 5%, 10%, 20%의 증가에 대한 민감도 분석을 실시한 결과 대안1의 경우 교통량의 변화 및 화물통행의 시간가치의 증가시 사회적 편익이 오히려 감소하였고, 대안2와 3의 경우 사회적 편익이 증가하는 것을 알 수 있었다. 이는 경부고속도로의 화물차량의 구성비에 따라 대안 1의 경우 오히려 화물차의 통행시간이 증가함에 그 원인이 있다 할 것이다. 이상과 같은 결론을 통하여 경부고속도로상의 화물전용차선의 설치시는 수답렬 교통량의 구성비와 구간 평균교통량에 의하여 그 효과가 다르게 나타남을 알 수 있었다. 따라서 물류비용 절감차원에서의 화물전용차선의 설치는 본 연구에서 나타낸 방법과 같이 수단간의 경제적 편익을 고려한 구간별 시간대별 효과분석을 통하여 정책의 시행여부가 결정되어야 할 것이다. 한편, 화물전용차선의 설치로 인한 물류비용의 절감을 보다 효과적으로 달성하기 위해서는 종합류류 전산망의 시급한 구축과 함께 화물차의 적재율을 높이고 공차율을 낮출 수 있는 운송체계의 수립이 필요한 것으로 판단된다. 그라나 이러한 화물전용차선의 효과는 단기적인 치유책일 수밖에 없기 때문에 물류유통 시설의 확충을 위한 사회간접자본의 구축을 서둘러 시행하여야 할 것이다.

As geopolitical, archaeological and strategic interests on cooperation with countries in the Far Eastern Area is gradually increased, countries are competing to attract or install a logistics or manufacturing hub in their countries. In this study, we investigated the relative importance of factors on the main three and nine detailed criteria from the domestic and overseas experts on Far Eastern Area. Using AHP(Analytic Hierarchy Process) analysis, priority importance of factors was derived. As a result, we find that the most important factor was economic factor. In detail, industrial complex creation was the highest factor and the institutional guarantees for the investment on policy and transportation network was second highest factor. Based on analysis result, specific competitiveness level in the 10 region of Far East was follows. Hunchun, Vladivostok, Yanji, Tumen, Rajin, Hassan, Ussuriysk, Cheongjin, Mihaylov Skiing, Nije Jeuchinski were showed in order. Hunchun showed the highest competitive level in location, topography, compliance to the around cities, transportation network, industrial complex, excellence in logistics facilities, long-term investment plans, institutional guarantees for investment, customs efficiency and political stability. However, in other factors such as population and number of households, public facilities, potential demand and resource utilization, Vladivostok showed the highest level.

In 2017, the government of Duterte, in the second year of the ruling, more strongly promoted peace and order policies and expressed independent diplomacy as the chairman of ASEAN. He continued to fight against drugs and tried to increase his political legitimacy through the punishment for corrupt officials. He also declared martial law in the Mindanao region because of the dissolution of the Maute group, a Muslim terrorist organization, and strengthened counterterrorism cooperation externally. In addition, as to Communist militants, he took the initial reconciliation gesture and promoted peace negotiations, however, concluded the peace tide and started the suppression operation due to a series of bloodshed. He still has a strong drive in peace and order issues, backed up by high support rate, but it is becoming a factor of anxiety as the socioeconomically underprivileged and minority groups are increasingly alienated. As the chairman of ASEAN, Duterte has a certain distance from the United States, which is a firm ally, but has turned to increase familiarity with China and Russia, which can take substantial economic benefits. Through diversifying the external economic support and increase of tax revenue, the priority task was to establish the infrastructure. Although the Philippines, which has a high economic growth rate, has a strong expectation that it can establish a solid infrastructure, tax reforms should be successfully completed in order not to repeat the previous failures, which has traditionally increased foreign debt burden by relying on external resources. It seems that it is necessary to find the meeting point of the foreign policy of Duterte and new Korean government's New Southern Policy, and to find possible economic cooperation policies to improve Philippine infrastructure.

The purpose of this study is to analyze the effects of CCTV installation empirically in the economic and spatial aspects(crime displacement and diffusion effects of crime control benefits), targeting S city in Korea. In terms of economic effects, caused by CCTV installation(2012 and 2013), cost benefit analysis was conducted by means of CCTV installation costs, crime cases, and crime costs per case. The result shows that there is positive effect of 1.34(34%) in 2012. This is slightly higher than the previous study results in Korea(cost effectiveness 1.32), but a little lower than the USA cases(cost effectiveness 1.49). In the case areas in S city, the result proves that the new CCTV has gained economic profit through the crime reduction, compared to the installation expences. However, the cases in 2013 shows no economic profit effect. Secondly, an analysis was conducted in the spatial aspect(crime displacement and diffusion effects of crime control benefits) by using the analysis tool of crime displacement value called WDQ. The results are summarized as follows: The total crimes in three regions had crime diffusion effect but it was less than the direct effect, while in one region, displacement effect was found, but they were less than direct effect. In the case of theft and violence, CCTV had a positive effect, except for one region. The results of the analysis were totally different. Judging from this difference, it may conclude that the effects of CCTV are different by the types of crimes and the places of crimes. The results of this study is meaningful in that it examined and evaluated the effects of the CCTV by scientific and rational measurement tools where previous studies are not many. In addition, it has policy implication for the validity of CCTV and making effective installation plan for crime reduction and prevention.

Mobile wallet that can keep coupons and membership cards for mobile is one of rapidly growing services due to its usability and financial benefit. However, in spite of its rapid growth, the increase of users who do not use continuously it is an important consideration to service providers for making a profit. This study aims to test the effects of factors affecting the continuous use intention of mobile wallet based on VAM (Value-based Adoption Model) which can analyse them in both benefit and sacrifice aspects, so as to suggest considerations to increase the use period of mobile wallet for service providers. The research findings supported the hypotheses regarding to the effects of usefulness, value-expression, perceived security and enjoyment in the benefit aspect and technicality in the sacrifice aspect on perceived value. In addition, the causal path from perceived value to continuous use intention was significant. The study results are expected to be used in marketing or service improvement for short-term users by taking account of emotional factors as well as functional factors.
