In 2017, the United Nations reported that the population aged 60 and above was increasing more rapidly than all younger age groups worldwide, projecting that by 2050, the population aged 60 and above would constitute at least 25% of the global population, excluding Africa. The world is experiencing a decline in the rate of increase in the working-age population due to global aging, and the younger generation tends to avoid difficult and challenging occupations. Although theoretically, AI equipped with artificial intelligence can replace humans in all fields, in the realm of practical information security, human judgment and expertise are absolutely essential, especially in ethical considerations. Therefore, this paper proposes a method to retrain and reintegrate IT professionals aged 50 and above who are retiring or seeking career transitions, aiming to bring them back into the industry. For this research, surveys were conducted with 21 government/public agencies representing demand and 9 security monitoring companies representing supply. Survey results indicated that both demand (90%) and supply (78%) unanimously agreed on the absolute necessity of such measures. If the results of this research are applied in the field, it could lead to the strategic development of senior information security professionals, laying the foundation for a new market in the Korean information security industry amid the era of low birth rates and longevity.

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.

The purpose of this paper is to understand the underlying dynamics for the share market bubbles in China during the most recent decade. By using the behavioral finance theory and the Shanghai Composite index prices during the periods from 2005 to 2008 and from 2014 to 2015 as the study samples, we find that the large volatilities in the Chinese share market are closely related to information blockage, which impedes share prices to timely respond to economic conditions as well as external shocks and increases (decreases) the demand of shares when the supply is difficult to adjust. Although the Chinese government has introduced a series of programs designed to increase more reliable information to the public, the share market still tends to confront issues of information asymmetry. The potential reason is that the reforms did not change the long-stand situation in China, where individuals or groups related to government bureaucracy who play a dominant role in the society are given priority to gain access and obtain information that benefits. By identifying the main reasons for the large volatilities in the market, policy makers are given advice as to which areas they may need to focus on to improve future market performance.
