The objective of this study is to analyze the research articles on clinical social work practice effectiveness to build a scientific and scholaristic image of clinical social work practice. The data for analysis were the articles published in 13 professional journals including Korean J. of Social Welfare in the period of 1979 to 1999. The appearance rate of effectiveness studies was 1.28% with only 18 articles. Experimental studies consisted only 4 out of 18, and there were only 10 Quasi-experimental studies. Statistical errors were observed in most studies, so it is too early to call that the clinical social work practice is either effective or not effective. In order to see the comprehensive trends of the clinical social work practice, other clinical papers were also examined. The appearance rate was also as low as 8.75% (effectiveness studies included). While 18 articles were about the therapy model, other clinical papers were about generic practice models. However, those newly developed generic practice models had not yet been widely used nor tested for effectiveness. Thus, the followings were suggested: active research activities with solid methodology, team work with the field, theory and method development, education and re-education, and collaborative team work with other related fields. It was also pointed that the cross analysis of research papers by the publishing period, authors major and other background variables would be useful.

Directed energy weapon enables to radiate the concentrated energy so as to result in distraction and overload of the target electronics. Analysis on effectiveness of weapon system can be important consideration in order to determine performance and design weapon system. In this paper, air defense weapon system, which is one of directed energy weapon system is studied. In order to analyze the effectiveness, the reflector antenna with high power circularly polarized horn antenna is designed, and power density in axial effective area is simulated and calculated using Friis formula. Through the study, the validity of antenna system is verified, and the effectiveness of directed energy weapon system on the target is evaluated.

In this study, a new kind of instrument for measuring the magnetic shielding effectiveness (MSE) was developed using a double yoke; one a magnetizing yoke and the other a sensing yoke. Using the developed instrument, the MSE could be measured for a steel sheet specimen in the ELF range, where the magnetic permeability contributes to the MSE at low frequencies and eddy currents contributes to the MSE high frequencies with < 0.1 dB reproducibility. The developed measuring method can be applied to quality control in a steel sheet company producing EMI/EMC shielding materials.

Knowledge transfer among employees integrates individual knowledge scattered within a firm, thus increases organizational effectiveness. In particular, the role of knowledge broker, which enables knowledge sharing across multiple teams or subunits, is critical for the success of knowledge management. This study classified the types of knowledge broker that facilitates knowledge flows among team, and examined the influences of various intra- and inter-team social networks. Survey responses from 128 employees of four R&D teams were gathered and analyzed using partial least square structural equation modeling. The results of analysis showed that all types of inter-team networks(i.e., emotional closeness network, frequency of interaction network, and perceived expertise network) had significant influences on related knowledge brokerage behaviors. In case of intra-team networks, only the emotional closeness network showed significant influence. These results proved the necessity of managing various types of intra- and inter-team networks to encourage knowledge brokerage behaviors within a firm.

A Purpose. As organizations become more team oriented, research on teams continues to increase especially involving how teams contribute to organizational performance and effectiveness. Although there has been existing research on Kaizen teams in the private sector, very little research has included Kaizen teams in the public sector. In this paper, we present a method to study Kaizen teams in a local Spanish government that have been using Kaizen teams for more than ten years. Design/methodology/approach. Quantitative research was adopted for this study. Twenty teams participated in the study by filling out the Team Learning and Development Inventory (TLI) proposed by Lingham (2004). In addition, we interviewed members of the teams in order to clarify and assure our quantitative results. Findings Based on the findings, we propose that Kaizen teams should practice both Continuous (CI) and Process Improvements (PI) in their projects. We also propose that Kaizen teams should not be teams skilled only at developing better improvement processes (both CI and PI) for the organization but that such teams should also be skilled at engaging in team development using both CI and PI processes internally-a Kaizen within Kaizen teams approach. Research limitations. Its based in one case study. However, it is working paper and the research project still is developing. Practical Implications (if possible). Serve as a guide to practitioners (Public managers) who desire to understand how their Kaizen teams involves both internal (conversational spaces) and external (methodology) perspectives that would contribute to both team and organizational effectiveness. In this paper, we focus on the Internal Processes (both CI and PI) using the TLI as an effective method for Kaizen teams to engage in the Kaizen process. Originality/value. This study is one of the first to look at team's performance using Team Learning and Development Inventory in Spain's public sector. It is also the first to mention about the relationship of the team's performance and the implementation of process improvement methodologies in Spain local government environment.

It has little possibility that cable and cable joint causes any problem in transmission system. But when cable fault occurs, the damage is very severe. There are weak points to have potential problem due to many cable joint especially in high voltage transmission line. In this study, we propose nobel method to detect PD in cable joints and show the effectiveness of the proposed method through experiment results.

The present study examines the effects of transformational leadership exercised by team leader and transformational leadership shared by team members on team creativity and team performance at the team level. A growing body on leadership research highlights the role of team leadership in work organizations. In team settings, studies have focused exclusively on individual leaders who occupy formal leadership positions and exercise vertical influence over team members. In contrast to this traditional approach, shared leadership highlights a horizontal influence process where leadership is collectively carried out by team members. In this shared form of leadership, members actively participate in the leadership process and horizontally influence other team members. This mutual influence among team members constitutes a critical condition for the success of team-based organizations. The ability of team members to work together as a team is the key to the overall functioning of the team organization. To verify the effect of two leadership styles, we analyze the effect of a leader's transformational leadership and members' shared transformational leadership on team creativity and team performance for the same team. This study also predicts that the transformational leadership shared by members will moderate the effects of leader transformational leadership on team performance and creativity. Our findings show that both leaderships have a positive effect on team performance. However, the main effect of a leader's transformational leadership on team creativity is not significant when members' transformational leadership is employed into the model. With the effect of leader transformational leadership controlled for, the main effects of the transformational leadership shared by members on team creativity and performance are significant. In addition, we also found the significant moderation effects of member transformational leadership by leader transformational leadership on team creativity. Based on these findings, we strongly recommend that team based organizations shift the leadership focus from the leader focused leadership model to the shared leadership model. We also discuss managerial implications of our findings in details.
