Historically, the approach to any reconstructive challenge, whether intentionally or intuitively, can be seen to follow distinct guidelines that could aptly be called "reconstructive metaphors." These have been intended to inform us as to the "what, "when" and "where" this attempt can best be achieved. Yet the "how" or means to accomplish this goal, usually also intuitively well understood, in a similar vein can now be expressed to be within our "reconstructive toolbox." The latter will distinctly mirror our individuality and contain not only the various hardware that we deem essential, but also the means to access whatever technology we may be comfortable with. No toolbox, even if overflowing will ever be full, as potential options and the diversity they represent surely approaches infinity. But the truly excellent reconstructive surgeon will know when their toolbox is in any way lacking, and fears not remedying that deficiency even if the talents of another colleague must be sought, so as always to ensure that the patient will obtain the best appropriate treatment!

In this study, we are trying to verify humidity control capability of the exhibition environment of cultural property by measuring adsorption and desorption performance, the control ability of harmful substances by the adsorption experiments of harmful gases. In the experiment of adsorption and desorption performance, in the low humidity area, Artsorb desorbed overwhelmingly more than activated carbon whereas activated carbon absorbed more. Adsorption speed was faster slightly in Artsorb absorption speed was similar in both. In the middle humidity area, absorption by artsorb was slightly more and desorption was similar in both so characteristic of Artsorb didn't appear. Also, Adsorption speed was faster in activated carbon but in the process of desorption, the speed of Artsorb was faster. In adsorption experiment of harmful substances, the concentration in the environment with activated carbon was lower than one with Artsorb, but the difference appeared small. And as a result of observation of the difference in concentration due to adsorption of harmful gas by the change in the metal specimen, the most change was shown in lead specimen and the color difference between the lead specimens of the activated carbon and Artsorb appeared greatly.

This study aims to confirm the effect of different types of interpersonal stress factors of private security officers that are prevalent in the course of carrying out their duties on job satisfaction and turnover intention. The authors have examined 175 of the 200 survey questionnaires distributed to the employees of private security firms located in Seoul and Gyeonggi Province in December 2012. The result of the analysis indicates that the primary source of stress in the private security officers is the interaction with customers, followed by the relationships with colleagues and superior officers. In addition, colleague-related stress is found to be the only interpersonal stress factor with a statistically significant negative effect on job satisfaction, while both the stress from the relationships with colleagues and superior officers are positively correlated with turnover intention. Furthermore, the colleague-related stress is revealed to mediate job satisfaction which has a statistically significant effect on turnover intention. The result from the study emphasizes the importance of managing the interpersonal stress in private security officers and confirms the necessity of effectively handling the stressful situations in the relationships with colleagues. Moreover, in order to raise job satisfaction levels and minimize turnover which is vital in accomplishing the goal of each organization, causal factors of the stress need to be recognized and handled appropriately. This will provide the future research with an insight into the effective interpersonal stress management and examining other factors of job satisfaction and turnover intention of private security officers.
