The purpose of this study is to examine the relationship between CIO's characteristics and CIO's role. The CIO's characteristics include CEO/CIO relationship, CIO's power in his/her organization, hire type of CIO, and career background of CIO. The results of this study are as follows: part of the CIO's characteristics has a positive relationship with the CIO's role. In other words, the CIO's role is influenced by the CEO/CIO relationship, the CIO's power, and the hire type of CIO. However, the relationship between the career background of the CIO and the CIO's role is not statistically significant.

The mechanisms of the electrode reaction of chlorate ion were investigated, using Pt-electrode, by means of the technique of galvanostatic double pulses. For double current pulses (a cathodic pulse followed by an anodic pulse), the mechanism of the electrode reaction of chlorate ion over a current density range from 20 ma/cm2 to 25 ma/cm2 was suggested as the following: $CIO_3^-\;{\longrightarrow^{I}_{n_{1c}}\;CIO_2^-\;{\longrightarrow^{II}_{n_{2a}}\;CIO^-\;{\longrightarrow^{I'}_{n_{1a}}\;CIO_2^-\;{\longrightarrow^{II'}_{n_{2a}}\;CIO_4^-$ For a higher current density from 40 ma/cm2, it was suggested as the following: $CIO_3^-\;{\longrightarrow^{III}_{n_c}}\;CIO^-\;{\longrightarrow^{I'}_{n_{1a}}\;CIO_2^-\;{\longrightarrow^{II'}_{n_{2a}}\;CIO_4^-$ or $CIO_3^-\;{\longrightarrow_{n_c}}\;CIO^-\;{\longrightarrow_{n_a}}\;CIO_4^-$

This paper studied the impact of CIO leadership on the IS performance. The survey was developed to measure the relationship between CIO leadership style and the IS performance. The study shows that the differences in CIO leadership style along the two dimensions of goals and modes do not cause a statistically meaningful difference in business efficiency, one of the IS performance. Contrary to the existing studies that suggest a balanced leadership is effective, this study illustrates that strategic leadership and enabling leadership are more effective in the aspects of targets and manners respectively. This study does contribute to the introduction and utilization of CIO: unlike existing studies on leadership, it proposes a new approach to classifying leadership style based on the styles exhibited by CIO's flexibly from one situation to another. It will provide companies considering appointing CIO's or already using CIO's with insights into effective CIO role. It is important to provide CIOs with position and authority to exhibit their leadership flexibly.

The present study was investigated the effects of chlorine dioxide ($CIO_2$) on the rcspimtory metabolism of olive flounder (Parolichlhys olivaceus) imtermittently exposed to seawater chlorinated by $CIO_2$:. Oxygen consumption of flounder before and after once or twice $CIO_2$-treatment with 12 hr- or/and 24 hr-interval were serially measured with automatic intenniteent-flow respirometer system (AIRS). The oxygen consumption rates of flowKier exposed to 0.10 and 0.20 ppm$CIO_2$, were not different from the control fish prior to the once or twice chlorinations . On the other hand, the respiratory metabolic rates of flounder exposed to 0.30 ppm$CIO_2$ were significantly increased 15% and 22 - 23% after the once and twice chlorinations compared to the control fish. respectively. The flounder exposed In 0.40 and 0.50 ppm$CIO_2$: died within 4 hr and I hr. respectively. The elevation( respiratory metabolism in flounder exposed toO.30 ppm$CIO_2$ and above is considered due to physiological stress caused by $CIO_2$ exposure.

It is important to investigate into the critical success factors of the CIO system in order to formulate a successful introduction strategy of the system. In an effort to provide the background of the strategy, this research attempts to identify the characteristics of CIO's environment in Korea, such as the CEO, the colleagues, and the demographic statistics of the firm the CIO works for. A result from the analysis of data collected shows that about half the firms who responded to the survey have already adopted the CIO system. This implies that the value of the system is well recognized in Korea, considering that many of another half the firms are planning to adopt the system. Another result suggests that the bigger a firm is, the more the firm tends to adopt the CIO system and the higher the rank of CIO's colleagues is.

The steady increase in academic computing activities on campus have blurred the distinctions between Academic Libraries and Computer Centers. Considerable attention has been focused in recent years on the cooperative relationship between these two separate campus units. This article explores collaboration of two units in Chief Information Officers (CIO) organizational model that have a number of colleges and universities in America, proposes an application programs in CIO Organizational Model in order to use National Colleges and Universities. Therefore, This author undertook a study of convergence of information technology and the organizational relationships among information management positions In campus, and sought on CIO's decision-making roles, their responsibility, various CIO organizational models. The models described can help a college or university identify the administrative configuration most suitable for its campus culture.

This study examined the relationship among constructs that impact on strategic use of IS(Information Systems). Independent variables were OIQ(Organizational Intelligence Quotient) and role of CIO(Chief of Information Officer) as a top manager, and dependent variable are strategic use of IS. The dependent variable has three-sub constructs: 1) IT infrastructure flexibility; 2) operation-orientation; and 3) market-orientation. Seven research hypotheses derived from the research model, and were empirically tested using the PLS (Partial Least Squares) method. The research results confirmed that both OIQ and CIO's roles have strong impact on organizations' strategic use of IS. Communication and business network among the sub-constructs of OIQ have effect on strategic use of IS. CIO's role as a top manager was found to be significant. CIO's role as a resource allocator and innovator among the CIO's roles showed significant influence on strategic use of IS. OIQ was also significantly related to CIO's role as a top manager. This study suggests practical implications and insights to the enterprises which aim to apply IT strategically.

This study was conducted to estimate the effects of residual chlorine dioxide ($CIO_2$) in chlorinated seawater on survival and physiological responses (hematocrit: Ht, hemoglobin: Hb, serum electrolyte and glucose levels, and osmolality) of olive flounder, Paralichthys olivaceus. All the flounders were exposed for 10 min to different concentrations of residual $CIO_2$ just after chlorination for 1 min in each experimental aquarium (EA). ClO$_2$-free seawater was continuously supplied to each EA after 10 min exposure to $CIO_2$. By means of probit analysis, the median lethal times (LT$_{50}$, min) of flounder exposed to 0.43 and 0.51 ppm $CIO_2$, were at 103 and 32 min, respectively. In the range from 0.34 to 0.51 ppm $CIO_2$, the values of Ht, Hb, electrolytes and osmolality of fish exposed to $CIO_2$ were significantly elevated as elapsed time and residual concentrations of $CIO_2$ increased after chlorination. The levels of Ht, Hb, electrolytes and osmolality in flounder exposed to 0.27 ppm $CIO_2$ were not significantly different compared to control fish, which were maintained in $CIO_2$-free seawater; however, the levels of serum glucose were significantly increased with elapse times.

The role of CIO is examined in the context of three successful e-government implementations in the U.S. The leadership role of CIO turns out to be crucial to the utilization of information technology for competitive gains: cheap government, speedy service, and increased satisfaction of citizens. A balanced leadership model emerges. An effective CIO should strike a balance between strategic and operational leadership roles, as well as between forceful and enabling leadership roles. To take a maximum advantage of IT, we propose government CIO positions with responsibility, power, and qualification specified along the balanced leadership model need to be created in Korea through legislation.
