박명찬,윤성환 慶熙大學校 社會科學硏究院 2007 社會科學硏究 Vol.33 No.2

This study tries to analyze what the most significant factors are in Brazil, where the Korean investing firms have to overcome and adapt to various difficulties, especially in terms of political environment. This main purpose of this research is to test empirically some relations of between the managing strategy of Korean firms and the environment factors of politics in Brazil while this is conducted in two stages. First, the research model is designed by reviewing relevant theories, previous studies, and the current investment conditions in local Brazil. Second, the survey of Korean firms engaged in investment activities in there is done by collecting questionnaires from them. with this survey, the strategic method of multiple regression is used to testing some hypotheses. 본 논문은 브라질 현지에 진출하여 직접 경영활동을 수행하고 있는 한국기업들이 직면하고 있는 정치적 환경요인이 무엇인가를 규명하고 이에 어떠한 대응책을 마련하여 경영활동을 전개하고 있는 가를 밝히기 위한 것이라 할 수 있다. 기업의 경영활동에 영향을 미치는 일반 환경요인과 산업 환경요인 중에서 일반 환경요인으로 연구의 대상을 제한하였는데 그 이유는 기업이 오히려 일반 환경에 대한 분석을 체계적으로 실행하고 있지 않다는 지적이 있기 때문이다. 그리고 일반 환경요인 중에서 정치적 환경요인만을 분석에 대상에서 포함시켰는데 기업의 현지경영활동에 가장 직접적이고 가시적인 영향력을 행사하기 때문이다. 선행연구를 통해 문헌분석을 실행하였고 이를 토대로 연구가설을 설립한 후 이를 검증하기 위한 실증분석을 실시하였다. 실증분석 결과, 브라질 현지에서 경영활동을 수행하고 있는 한국기업들은 현지의 정치적 환경요인 중에서 행정 관행 요인에 가장 큰 영향을 받고 있는 것으로 나타났다. 행정 관행 요인에 대처하기 위하여 합리적 위험관리와 네트워크 강화 전략을 동시에 실행하고 있는 것으로 밝혀졌다.

The forms of current war are diversified over the pan-national industry. Among these, one kind of threats which has permeated the cyber space based on the advanced information technology causes a new type of war. C4ISR, the military IT revolution, as a integrated technology innovation of Command, Control, Communications, Computer, Intelligence, Surveillance and Reconnaissance suggests that the aspect of the future war hereafter is changing much. In this paper, we design the virtual decoy system and intrusion trace marking mechanism which can capture various attempts and evidence of intrusion by hackers in cyber space, trace the penetration path and protect a system. By the suggested technique, we can identify and traceback the traces of intrusion in cyber space, or take a legal action with the seized evidence.

구ㆍ미주 관광객의 인구 특성요인과 기대 요인에 따른 만족도에 관한 실증적 연구 : 한국 관광기념품 구매와 관련하여 In relation to purchasing Korean Tourism Souvenirs

박명찬,고종원 한국관광정보학회 2001 觀光情報硏究 Vol.- No.9

The purpose of this paper can be said to analyze the satisfaction and preference of Europe and the Americas tourists visiting Korea to local tourism souvenirs using data their population characteristics factors and expectation factors before purchasing. As the paper process, the bibliographic research on related data issued by the authorized research institution for the country's inside and outside and empirical research by the distribution and collection of questionnaire for the purpose of showing the desires of Europe and the Americas tourists to Korean souvenirs products were performed in parallel. The contents of this research are summarized as below. As mentioned above, this paper is divide by two parts, the relevance between the population factors and satisfaction degree to Europe and the Americas tourists and the connection between the satisfaction degree and expectation degree to them. Among variables of Korean souvenirs such as art, originality, design and price, etc., Overall Europe and the Americas consumers are made clear as dissatisfied with art and originality of Korean souvenirs. Except these factors, other factors are classified with the scope of satisfaction to Americans. So For the sales increasing to Europe and the Americas consumers, these inferior factors have to be invested, researched and developed using the government's supports and related firms' core capabilities. such as marketing mix. Finally, in case of the relevance of satisfaction after purchasing and expectation before purchasing by Europe and the Americas consumers. All factors like design, packaging, price, variety, art, originality are satisfied with them as showing positive significance between them. So this result lets us think that Korean souvenirs have international competition to Europe and the Americas tourists. Therefore, the firm will keep the increasing intensity of global competition.

Novel Fabrication of Au Nanoparticle Film on a Polyelectrolyte-coated Glass for Efficient Surface-enhanced Raman Scattering

박명찬,신권수,이지원,김관 대한화학회 2015 Bulletin of the Korean Chemical Society Vol.36 No.3

In this paper, we report a novel method for the growth of gold nanoparticles on a polyelectrolyte-coated glass and its application as a surface-enhanced Raman scattering (SERS) substrate. Gold nanoparticles were readily grown on a polyelectrolyte-coated substrate using butylamine as the reductant of HAuCl4. The Au nanoparticles formed on the polyelectrolyte-coated substrate exhibited superior SERS activity compared to an electrochemically roughened Au substrate or a vacuum-evaporated Au film. In addition, our Au substrate shows excellent reproducibility and noticeable stability as an SERS substrate. The proposed strategy is simple, cost effective, and reproducible for the mass production of gold nanoparticles films, irrespective of the type of the underlying substrates, which therefore are useful in the development of plasmonics and SERS-based analytical devices.

In the surgery of central area, idenwg the motor cortex in front of central sulcus is imperative to prevent loss of motor function. Twenty five patients with tumors or intractable epilepsy near the central sulcus were operated on at the Department of Neurosurgery of Chonbuk National University Hospital, from September. 1991 to December 1993. An estimated localization of lesions was performed with Callosal Grid System, which is a methodolgy made available by the development of high quality of magnetic resonance imaging, digital subtraction angiography and high resolution computerized tomography. This system allowed us to be oriented to the motor cortex as well as permitted assessment of the extent of resection. This was further delineated by direct electrical stimulation, which confirmed the functional motor cortex and made it possible to maximized the tumor resection near and in the motor cortex The combination of direct cortical stimulation (functional mapping) and the use of the Callosal Grid System (anatomical mapping) allowed us to idene the spatial relationship between them as well as to maximize the tumor resection in most cases without injury to the central area, so that the better outcome is guaranted.

현재의 침입차단, 침입탐지 등의 보안강화시스템은 공격자에 대하여 해당 트래픽만을 차단하는 수동적인 방어 시스템으로 실제 공격자에 대한 능동적인 대응이 부족하여 재공격 및 우회공격에 취약하다. 또한, 현재의 역추적 기술은 수작업을 통한 로그정보 수집 및 추적으로 인해 많은 시간과 인력이 필요하여 능동적 대응이 불가능하다. 본 논문에서는 현재의 인터넷 환경에 적용 가능하며, 재공격 및 우회공격에 대응하기 위하여 IP헤더에 마크를 삽입하여 추적하는 TCP 연결 역추적 기법을 제안한다. 제안된 기법은 기존 네트워크 구성요소의 수정이 불필요하고, 응답패킷에 XOR 연산 기법을 적용하여 마킹되는 정보의 양과 자원의 오버헤드를 줄일 수 있다. Current security reinforcement systems are passive defense system that only blocks filter to all traffic from the attacker. So, Those are weak re-attack and Stepping Stones attack because active response about attacker is lacking. Also, present techniques of traceback need much time and manpower by log information collection and trace through the personal inspection and active response is lacking. In this paper, We propose technique for TCP connection traceback that can apply in present internet and trace to inserted marking on IP header to correspond re-attack and Stepping Stones attack. Therefore, Proposed technique is unnecessary correction of existing network component and can reduce size of marked information and overhead of resources.

A Smart Home is a technically expanded from home network that gives us a comfortable life. But still there is a problem such as mal function of devices and intrusions by malicious parties since it is based on home network. The intrusion by malicious parties causes a critical problem to the individual's privacy. Therefore to take legal actions against to the intruders, the intrusion evidence collecting and managing technology are widely researched in the world. The evidence collecting technology uses the system which was damaged by intruders and that system is used as evidence materials in the court of justice. However the collected evidences are easily modified and damaged in the gathering evidence process, the evidence analysis process and in the court. That's why we have to prove the evidence's integrity to be valuably used in the court. In this paper, we propose a mechanism for securing the reliability and the integrity of digital evidence that can properly support the Computer Forensics. The proposed mechanism shares and manages the digital evidence through mutual authenticating the damaged system, evidence collecting system, evidence managing system and the court(TTP: Trusted Third Party) and provides a secure access control model to establish the secure evidence management policy which assures that the collected evidence has the corresponded legal effect.
