A structural break in the level as well as in the innovation variance has often been exhibited in economic time series. In this paper we propose robust unit root tests based on a sign-type test statistic when a time series has a shift in its level and the corresponding volatility. The proposed tests are robust to a wide class of partially stationary processes with heavy-tailed errors, and have an exact binomial null distribution. Our tests are not affected by the size or location of the break. We set the structural break under the null and the alternative hypotheses to relieve a possible vagueness in interpreting test results in empirical work. The null hypothesis implies a unit root process with level shifts and the alternative connotes a stationary process with level shifts. The Monte Carlo simulation shows that our tests have stable size than the OLSE based tests.

By analyzing a nation-wide survey, this article examines research related norms and values of 684 scientists in 16 universities and 7 government supported research institutes. The survey shows that Korean scientific community tends to reject communality and disinterestedness while it accepts universalism as a norm. Organized skepticism is received a lukewarm support. In contrast, Korean scientific community tends to perceive the intellectual property and secrecy as legitimate and believe that scientists should consider the applicability of scientific research outcome and its social impacts when they choose research topics. When other variables are controlled for, the more basic research a scientist conducts the scientist is more likely to support communality and reject secrecy. The younger scientists are less likely to accept disinterestedness and the claim that the scientists should keep distance from social issues than the older. Scientists who work in the government-supported research institutes are more likely to view secrecy for more than 6 months as legitimate and reject the claim that science should not be affected by society than university scientists. The implications of these findings are discussed.

Leader-Member Exchange (LMX) model of leadership has suggested that members within the same work team are differentiated in terms of their level of the quality of leader member relationships. However, the differentiation in leader member relationships has not been examined for its possible team-level effects. In this study, the possible impact of this role differentiation on team members' affective reactions was explored. As hypothesized, teams whose members experienced higher level of LMX tended to have higher overall job satisfaction, organizational commitment, and team efficacy. Contrary to expectation, however, the team-level mean on LMX was not related with team-level variability on LMX. Based on these findings, several theoretical and practical Implications are discussed.

Information technology's potential for changing processes is widely acknowledged and various information technologies exist as a tool making business reengineering possible. Groupware is one of information technology that typically work in concert to bring out change in processes. This paper attempts to explain the importance of groupware as a critical information technology for business reengineering by developing a methodology of applying groupware to business reengineering. In order to understand the applicability of groupware to business reengineering, this paper has the following objectives. 1) Examines how the capability of groupware can play as a chang lever or enabler of process innovation explicitly. 2) Propose a integrated business reengineering methodology that incorporates process, process environment and information technologies specifically. A case study was used to provide the insight how groupware can play as a enabler of process innovation. The case was analyzed according to the reengineering methodology we proposed.

In the 1970s, the term Post - Modernism came into use to lable work of graphic design who broke up the Swiss style that had defined clarity and order. The characteristics of Post - Modernism graphic design include pluralistic and eclectic style. Those innovation of graphic design concerned with our social, political. cultural, and econonic changes. Deconstruction is one of the theory of Post-structualism. Deconstruction refers to the breaking down of metaphysics, rationalism, totality and so on. Deconstructive graphic design destroys traditional harmony even more than Marinetti's claim. Totality in graphic design seems to be ignored. Post - Modernism in architecture appears as historical revivalism and pluralism. The eclectic revivals and eccentric reinventions in graphic design are far too pluralistic and diverse to fit such as a simplistic system of style. Another innovation in graphic design occurs by electronic revolution. The impact of computer upon graphic design is becoming even more pronounced. Most importantly, Post-Modernism can consider the rediscovered freedom in graphic design. Graphic design is undergoing profound changes. But the essence of graphic design as com$$\mu$ication tools will remain unchanged.

This paper aims to develop the intellectual capital (IC) indicators which are the most available for the E institution, a typical type of public research institute in Korea. In this paper, we basically adopted the "Intangible Assets Monitor" proposed by Sveiby and comprising three kinds of intellectual capital, namely human capital, internal structure capital and relationship capital, as a research framework. For this work, we firstly identified 12 categories and 27 components of intellectual capital for E institution. Next, we extracted 37 main indicators and 94 sub ones from these categories and components as a whole. As a result, it may be the first time in Korea for E institution of develop its own IC indicators which are slightly, or sometimes totally, different from ones for private companies in the perspective of their organizational attributes and characteristics.

In today's R&D environment, as the complexity of IT systems increases and the expected quality level for R&D outcomes enlarges, it has been critical issues for us to effectively define and improve the R&D standard processes tailored for our organization and projects. To meet this needs, we defined the R&D standard processes based on the international standards for systems and software engineering and our existing traditional work methods, and then applied them of our ongoing projects. Now, we are improving our defined R&D standard processes continuously by monitoring of the processes and products and through the feedback of the application results. In this paper, we introduce the R&D standard process model developed by our organization (E research Institute in Korea) and the requirements and approaches used for their development and improvement. We compare our defined R&D standard processes with ISO/IEC 15288 which is the international standards for systems engineering and summarize the lessons learned through their development and improvement.
