Export performance has been a core topic in export marketing research. This study aims to investigate the relationship between adaptation/standardization strategies and export performance obtained after implementing each of these strategies to marketing mix variables. It is expected that the study results will help companies better understand an efficient marketing mix and applicability of adaptation/standardization approaches in their export ventures. New Zealand exporting firms which actively seek for export markets in Korea are selected for empirical analysis of this study. Adaptation and standardization are concepts that signify the level of intensity in each strategy; both have advantages and weaknesses. In the case of adaptation approach, it is shown that the difference in export performance between satisfactory and non satisfactory export ventures is statistically significant in marketing mix variables such as price, place and promotion. However, product variables affect statistical significance on export performance between satisfactory and non satisfactory export ventures in standardization approach. This study implies that when a company exports its product overseas, standardization effort is more important for product variables whereas much effort needed in adapting marketing variables such as price, place, and promotion to get satisfactory export performance.

Biplot is a useful graphical method to explore simultaneously rows and columns of two-way data matrix. In particular, canonical correlation biplot is a method for investigating two sets of variables and observations in canonical correlation analysis graphically. For more than three sets of variables, we can apply the generalized canonical correlation biplot in generalized canonical correlation analysis which is an expansion of the canonical correlation analysis. On the other hand, we consider the set of covariate variables which is affecting the linearly two sets of variables. In this case, if we apply the generalized canonical correlation biplot, we cannot clearly interpret the other two sets of variables due to the effect of the set of covariate variables. Therefor, in this paper, we will apply the partial canonical correlation analysis of Rao (1969) removing the linear effect of the set of covariate variables on two sets of variables. We will suggest the partial canonical correlation biplot for inpreting the partial canonical correlation analysis graphically.

유역 모형은 강우가 유출에 이르는 과정을 수문학적으로 재현해낼 수 있는 도구이다. 초기의 모형은 간단한 수준에서 유출과정을 모의하는데 그쳤으나, 기술이 발전함에 따라 유역 모형에 적용되는 매개변수의 수가 점차 늘어나게 되며 이론적 신뢰성과 복잡성을 동시에 갖게 되었다. 유역 모형은 집중형 모형과 분포형 모형으로 대별할 수 있는데, 기존에는 저류 함수법을 근간으로 하는 개념 기반의 HEC-HMS HEC-RAS 등과 같은 집중형 모형을 널리 사용한 반면, 점차 격자 기반에서 물리적 계산을 통해 유출 과정을 모의할 수 있는 GSSHA, Vflo, SWAT과 같은 분포형 모형의 활용이 늘어나고 있는 추세이다. 집중형 모형은 관측자료를 통해 산정된 경험식에 의존하고 있는 반면, 분포형 모형의 경우 각 격자가 가지고 있는 시·공간적 매개변수를 통해 물리적으로 유출과정을 계산하여 신뢰성을 확보하기에 유리하며, 미계측 유역에서도 활용이 가능하다. 지하수는 유역 모형의 댜양한 매개변수들 중 지표면 유출량에 밀접한 영향을 미치는 인자이다. 그럼에도 아직까지 경험식에 의존한 집중형 모형이 주를 이루고 있는 국내에서는 분포형 모형에 적용가능한 매개변수 최적화에 대한 연구는 미진한 실정이다. 이에 본 연구에서는 분포형 유역 모형의 침투모의 과정에 관여하는 공간 매개변수 중 밀접한 연관을 띠고 있는 대수층 깊이에 대하여 분석하였다. 여러 공간매개변수 중 침투능과 관계가 깊은 대수층 깊이에 대해 가장 적합한 매개변수 값을 도출해 내는 것이 본 연구의 최종 목적이라고 할 수 있으며, 분석은 국내 자연하천 유역을 대상으로 분포형 유역 모형에 일반적인 수준으로 적용할수 있는 범위를 검토하였다. 본 연구를 통하여 분포형 유역 모형에서 하나의 매개변수인 대수층 깊이의 정량화에 기여되기를 바란다.

Recently, IT Governance has emerged as the new keyword in the IT world. However, the multiple definitions and concepts that exist for this word are causing confusion among observers. Thus, in order to clarify the conceptual meaning behind the term 'IT Governance' once and for all, this study reviews previous literature and defines the sub construct of IT Governance. Then, we develop the measurement instrument for IT Governance, which results in three domains: IT resource and performance management. IT project management, and IT service management.

The performance analysis code has been developed for vertical take-off and landing(VTOL) UAV which can be utilized as a trade analysis tool in the pre-conceptual design phase. The UAV requires VTOL capability and high speed cruise performance. The main logic of this performance analysis code is to estimate performance parameters of each mission segment by mission fuel weight iteration. The reliability of this performance analysis code is discussed by comparing the data of existing dual flight mode VTOL UAVs such as Boeing CRW and Bell Tilt Rotor.

The purpose of this study is to identify the relationships among Social maturity(SM), Self-directed learning(SDL) and Self-concept of professional nursing(SCPN), and influencing factors of SCPN of nursing students. The survey was performed on 221 nursing students in two universities. Data were collected using a structured questionnaires and analysed with PASW 22.0. Study findings revealed that SCPN has a significant correlation with SM and SDL. Major satisfaction(${\beta}=.179$), Meaning on nursing(${\beta}=.274$), SM(${\beta}=.118$) and SDL(${\beta}=.211$) about SCPN were significant predictive variables. This variables accounted for 34.4% of the variance in SCPN. The findings indicate the necessity of developing educational programs to enhance nursing students's SM and SDL for increasing positive SCPN.

This study was carried out with the attention that the concept of entrepreneurial orientation has been applied at various levels of CEO, employee, management, and organization as a whole. The differences between these concepts were examined by discriminant validity and convergence validity, and the causal relationship between these concepts and performance was analyzed. A total of 96 questionnaires were collected and analyzed. The results show that CEO's entrepreneurial orientation, employee's entrepreneurial orientation, manager's entrepreneurial orientation and organizational entrepreneurial orientation have convergent validity and discriminant validity, and that these variables have different effects on the firm 's innovation performance and financial performance. In the analysis of the mediating effect, when the variables of all levels were put into a single variable, the innovation performance mediates between the entrepreneurial orientation and the financial performance in all variables. However, when all variables are applied simultaneously, innovation performance has mediating effect only on the relationship between organizational entrepreneurship orientation and financial performance. This shows that there is a conceptual difference according to applied level. As a result of the analysis of the causal relationship by the application level of entrepreneurial orientation, it is found that causality is formed among the entrepreneurial orientation variables. In particular, CEO's entrepreneurial orientation influences employee's entrepreneurial orientation, manager's entrepreneurial orientation, and organization's entrepreneurial orientation, and again, employee's entrepreneurial orientation and managerial entrepreneurial orientation form a causal relationship that influences organization's entrepreneurial orientation. In the relationship between innovation performance and financial performance, CEO's entrepreneurial orientation, organization's entrepreneurial orientation, and manager's entrepreneurial orientation are influencing innovation performance, and the only variables influencing financial performance are organization's entrepreneurial orientation. In conclusion, the limitations of the study and its future direction are presented.
