This study analyzes the factors affecting user resistance to ERP in Vietnam, including the factors related to the cultural values of the users, which is rarely dealt in the previous ERP research. A research model is developed based on Klaus and Blanton [2010] and Hofstede [2011], consisting of the independent variables ('cultural value', 'system', 'organization', and 'process' related variables), a dependent variable ('user resistance to ERP') and a moderating variable ('self efficacy'). Major results of study include (1) users with high degree of uncertainty avoidance and femininity regard ERP as potential threat to their job and are likely to resist to ERP; (2) By training the users with high level of femininity to enhance their self efficacy, the degree of resistance to ERP can be reduced; (3) For ERP to be utilized successfully, systems should be developed in such a way in which working with ERP is not regarded as complex and difficult; and (4) communication and training play an important role in reducing the resistance of users.

This paper develops a complete methodology for the mitigation of ionosphere spatial anomalies by GBAS systems fielded in the Conterminous U.S. (CONUS). It defines an ionosphere anomaly threat model based on validated observations of unusual ionosphere events in CONUS impacting GBAS sites in the form of a linear ‘wave front’ of constant slope and velocity. It then develops a simulation-based methodology for selecting the worst-case ionosphere wave front impact impacting two satellites simultaneously for a given GBAS site and satellite geometry, taking into account the mitigating effects of code-carrier divergence monitoring within the GBAS ground station. The resulting maximum ionosphere error in vertical position (MIEV) is calculated and compared to a unique vertical alert limit, or $VAL_{H2,I}$, that applies to the special situation of worst-case ionosphere gradients. If MIEV exceeds $VAL_{H2,I}$ for one or more otherwise-usable subset geometries (i.e., geometries for which the 'normal' vertical protection level, or $VPL_{H0}$, is less than the 'normal' VAL), the broadcast ${\sigma}_{pr_{-}gnd}$ and/or ${\sigma}_{vig}$ must be increased such that all such potentially-threatening geometries have VPL$_{H0}$ > VAL and thus become unavailable. In addition to surveying all aspects of the methods used to generate the required ${\sigma}_{pr_{-}gnd}$ and ${\sigma}_{vig}$ inflation factors for CONUS GBAS sites, related methods for deriving similar results for GBAS sites outside CONUS are suggested.

최근의 사이버 공격 위협 트렌드는 기업 또는 개인의 중요 정보 자산을 탈취하기 위해 기술적으로 광범위하게 해킹을 시도하는 방법과, 인간의 심리학적 요인을 겨냥한 사회공학(social engineering) 해킹 기법이 복합적으로 활용되는 '지능형 지속 위협 공격(APT)' 이 주를 이루고 있다. APT 공격 기법 중 가장 보편적으로 활용되는 스피어 피싱(spear phishing)은 약 90% 이상이 APT공격의 핵심 요소로 활용되며, 쉬우면서도 강력한 효과를 내는 해킹 기법으로 잘 알려져 있다. 사이버 보안 위협 방어를 위한 기존 선행 연구는 주로 기술적, 정책적 측면에 국한하여 접근하고 있다. 그러나 지능화된 해킹 공격에 맞서 선제적으로 대응하기 위해서는 사회공학 측면에서 기존과는 다른 관점의 연구가 필요하다. 본 논문은 스피어피싱 공격 사례를 중심으로 인간의 성격 유형(DISC)과 사이버 보안 위협간의 상호 연관성을 분석하고, 기존의 틀을 깨는 새로운 관점의 보안 위협 대응 방안에 대해 제안하고자 한다.

The rapid changes in consumption patterns and the manufacturing industry environment are both a threat and an opportunity for small and medium-sized enterprises in Korea because it lacks innovative capacity compared to large conglomerates. In this new manufacturing environment, social manufacturing is an innovative business model that can create new business opportunities for these companies. However, there are not that many proven models of platforms where products are created jointly with consumers. Some conceptual analysis of the success factors and operation strategy of co-creation platforms have started to be released but there are almost no empirical studies conducted on this matter today. In this study, the social manufacturing platform business concept and its components were studied; various factors that affect the willingness to participate in consumer-led co-creation platforms were considered; the factors were surveyed on potential consumers; a study was carried out to analyze the relationship of these factors; a model of these factors were set up and proven.

Globalization of economy brings both opportunities and threats especially for companies in developing countries such as Korea. Globalization is an opportunity because it may expand the size of market for the company where globalization brings a threat for developing global competitiveness. If the company has already built competitive advantage in its business domain, the company can easily transfer market growth to profit improvement. However, if the company has not developed competitive advantage, globalization of economy will give a serious threat for the survivor of the company. The company might lose its own domestic market share. For the less famous brand of product or company name, international expansion is a challenging strategy. The study evaluated organizational performance of companies that try international expansion by utilizing Miles and Snow's strategy typology. We clustered organizations based on their strategy typology (prospector, analyzer, defender, and reactor) in view of the level of product diversification, new product development instances, level of localization, and autonomy of foreign subsidiary. With the strategy typology, we evaluated international strategy in view of product competitiveness, marketing strategy, human resource strategy, and organizational strategy. The regression result demonstrates that the performance of the company is significantly higher when the company employs prospector strategy. We also found out that product quality and emphasis for developed countries in international expansion are the most important factors for success.

Among the 13 species of otters in the world, only one Eurasian otter (Lutra lutra) is found in South Korea. In the Korean Peninsula, otter pelts were historically valuable and expensive commodities used for international trade, and otters have long been poached as hunting animals. Recent rapid economic development in South Korea has increased habitat fragmentation and loss, creating a continuing threat to the natural environment. Otters live only in the area of rivers and streams as a family group and are territorial (linear habitat). Due to these limited conditions of otter habitat, the population size of otter is lower than that of onshore mammals. According to recent research, DNA analyses using microsatellite markers have shown that only approximately 7-21 otter individuals inhabit river systems for a length of 50-230 km. Korea's urban streams are associated with many threats that hinder otters from inhabiting them. Many areas around the urban streams are surrounded by high concrete riverbanks, and the risk of roadkill is also high. Nevertheless, ecological restoration projects in the urban rivers will contribute greatly to the stable inhabitation of otters. Detailed otter conservation strategies, such as the elimination of threat factors, improvement of habitat environment, and restoration of food resources and shelter, will provide a positive restoration effect on otter and river ecosystems as well.

본 논문은 광양항의 발전전략을 수립하기 위하여 SWOT/AHP분석을 실시하고자 한다. SWOT분석은 보통 전략수립단계에 있어서 내 외부 환경을 분석하기 위해서 사용된다. SWOT/AHP분석은 Kurttila et al(2000)이 SWOT분석의 유용성을 개선하기 위해 제안한 방법으로 SWOT분석의 결과는 단순히 SWOT그룹 내에 어떤 요인들이 있는가를 확인하는 것에 불과하다. 따라서 AHP분석과 결합함으로써 SWOT분석에서 도출된 요인들에 대한 상대적인 중요도를 평가하여 전략수립에 활용하는데 목적이 있다. 분석결과를 요약하면, SWOT그룹의 상대적 중요도는 기회(0.376), 강점(0.259), 위협(0.206), 약점(0.159) 순으로 나타났다. 다음으로 SWOT요인 별로 살펴보면, 강점요인의 상대적 중요도에서는 저렴한 화물처리비용(0.383), 우수한 항만입지(0.347), 광범위한 배후지(0.270) 순으로 나타났다. 약점요인의 상대적 중요도는 효율적인 통관시스템 미비(0.511), 복합운송 연계성 미비(0.315), 항만전문인력의 부족(0.173) 순으로 나타났다. 기회요인의 상대적 중요도는 각종 인프라 구축으로 수송체계 개선(0.461), 주변지역에 대한 연관산업단지 개발지속(0.326), 동북아지역의 물동량 증가추세(0.214) 순으로 나타났다. 위협요인의 상대적 중요도는 각종 인프라 구축으로 수송체계 개선(0.411), 주변항만과의 경쟁(0.400), 복합운송업체의 영세성(0.189) 순으로 나타났다. 평가대상이 되는 각 그룹별 세부요인들의 종합순위를 얻기 위하여 의사결정 항목들의 상대적 중요도를 종합화하였다. SWOT그룹별 세부속성요인들의 최종 중요도(가중치) 결과를 살펴보면, 기회요인 속하는 각종 인프라구축으로 인한 수송체계 개선(0.173), 주변지역에 대한 연관산업단지 개발지속(0.123)이 가장 높은 중요도를 보였고, 저렴한 화물처리비용, 우수한 항만입지, 항만운영의 융통성 결여, 주변항만과의 경쟁, 효율적 통관시스템 미비의 순으로 나타났다.
