Lots of the studies about the relationship between coaching leadership and organizational effectiveness have been conducted and reported that coaching leadership is one of the main factors which impact organizational effectiveness. The purpose of this study was to synthesize the relationship between coaching leadership and organizational effectiveness. For that purpose, 32 correlation effect sizes from 25 studies were analyzed by the CMA (Comprehensive Meta-analysis) Program. The study calculated the overall effect size of the relationship between coaching leadership and organizational effectiveness. Then, it also calculated the effect size of the relationship between coaching leadership and each sub-variable of organizational effectiveness. The analysis results are as follows: First, the overall effect size about the relationship between coaching leadership and organizational effectiveness was .519, which means that coaching leadership has over lager relationship with organizational effectiveness. In addition, the effect sizes of sub-variables of the organization are .556 (organizational commitment) .542 (job satisfaction), 509 (organizational citizen behavior), and .401 (innovative behavior). The study tested the mediating effects of measurements, organizational size, types of publication, and published year.

Purpose: This study intended to analyze the validity of clinical effectiveness data of clinical trials testing systemic titrated extract of Zea Mays L. unsaponifiable fraction chemotherapeutic agent. Material and Methods: Among 5 clinical trials claimed as proof of clinical effectiveness on the Web site of the manufacturer of this chemotherapeutic agent, a review of 4 clinical trials, written in either Korean or English, was conducted. Data were extracted from studies for the following variables: year of publication, age, sample size, follow-up period, combination with contemporary periodontal treatments, randomization, randomization check, blinded measurement, and statistical test type. Results: The study subjects' age intervals were too diverse to decide a common target population to generalize the findings. No study stated clearly the rationale for the sample size determination. Follow-up period to observe the start of clinical effectiveness was inconsistent and decided without any rationale of pathophysiological latent period. Randomization to make the comparisons on the same start line was performed but failed in a study. Randomization effect was not checked in 4 studies. Performance of blinded measurement of clinical outcomes to prevent bias was unclear in 2 studies. Type of statistical test was inappropriate in 3 studies. Conclusions: Based on the analysis of the validity of data on clinical and demographic variables, the four available clinical trials have not demonstrated compelling evidence of therapeutic effectiveness of systemic titrated extract of Zea Mays L. unsaponifiable fraction chemotherapeutic agent to improve prognosis of periodontal disease either with the contemporary periodontal treatment or without it.

There is a growing interest in researching new leadership and efficient organizational management due to the changes and spread of Information Communications Technologies (ICT) related organizations. Therefore, the purpose of this study is to examine the effect of leadership on organization in ICT R & D, and to follow the relationship between coaching leadership, leader member exchange (LMX), emotional intelligence of leaders, and organizational effectiveness. In order to verify this research problem, a total of 310 people were surveyed from employees working in the ICT R & D field. Reliability analysis of the measuring tool was tested on 80 pilot surveys in advance, and the final 285 data were used for empirical analysis excluding 25 unsatisfactory responses. For analysis, SPSS 22.0 program and AMOS were used to analyze the reliability, validity, path analysis, and control effects of the measurement tools. The findings demonstrate empirically the positive relationship between LMX and organizational effectiveness on coaching leadership in ICT R & D. In addition, by empirically verifying the effect that the emotional intelligence of the leader regulates the relationship between LMX, organizational effectiveness, and coaching leadership, then emotional intelligence of the leader can be usefully applied in ICT R & D. Furthermore, the demand for more in-depth research on coaching leadership, LMX, and emotional intelligence of leaders, which positively affects organizational effectiveness, was identified as demand for ICT R & D is increasing and horizontal and interactive leadership is needed.

In modern times, threat of high power electromagnetic wave is increasing. When the electrical grid and communication network are attacked by these high power electromagnetic wave, the whole infrastructure is paralyzed. To protect the infrastructure from these high power electromagnetic wave threat, the shielding facility that can block high power electromagnetic wave is constructed. Also shielding effectiveness evaluation about the constructed facility is important. But, because of space efficiency and saving of construction cost to construct the actual shielding facility, the shielding room wall is generally adjacent to exterior concrete structures. As space between shielding facility wall and concrete structures is very small, arranging the transmitting antenna exterior shielding facility is realistically difficult. Therefore, in this research, The shielding effectiveness measurement plan in the state of exterior narrow space of HEMP shielding facility is presented.
