Since the competitive environment, it has become common for firms to reduce its workforce to diminish operating cost. Accordingly, job insecurity among employees has been increasing. Previous works on job insecurity have not paid adequate attention to the influence of job insecurity on safety behavior. The current paper investigates the impact of job insecurity on safety behavior and its intermediating mechanisms. In specific, this paper delves into the mediating effect of job stress, as well as the moderating effect of servant leadership in the association between job insecurity and job stress. The results demonstrated that that job insecurity has a positive (+) influence on job stress, which has a negative (-) influence on safety behavior. Moreover, job stress mediated the association between job insecurity and safety behavior. Furthermore, servant leadership moderated the job insecurity-safety behavior link.

본 연구에서는 중소제조업 종업원들의 고용불안정성이 조직유효성에 미치는 영향을 분석하였다.그리고 이들 간 관계에 있어서 경영자에 대한 신뢰와 자기효능감이 조절효과를 가지는지도 실증적으로 분석하였다.가설검정을 위해 대구 및 경북지역 중소제조업을 대상으로 설문조사를 실시하여 238개 자료를 실제 분석에 활용하였다.분석결과 고용불안정성을 높게 지각할수록 조직유효성 변수인 직무만족은 낮아지는 반면,이직의도는 더 높아지는 것으로 나타났다.또한,고용불안정성과 직무만족 간 관계에 있어서 경영자에 대한 신뢰의 조절 효과는 유의미하지 않았으나,자기효능감은 조절효과가 있는 것으로 나타났다.그러나 고용불안정성과 이직의도 간 관계에 있어서는 이와 반대의 결과를 보여줌으로써 조절변수의 조직적 특성과 개인적 특성이 고용이 불안한 상황에서도 그대로 반영됨을 알 수 있었다.본 연구의 결과는 중소제조업 종업원들의 고용불안에 대한 심각성을 인식하고,이를 감소시키기 위한 구체적인 방안을 마련하고 적극적인 노력을 기울일 필요가 있음을 시사하고 있다.

The purpose of this study is to verify the relationships among innovative behavior, turnover intention, and job security. An additional purpose was to examine partial mediating effects on psychological ownership. The baseline of analyzing those relationships in this study is that the role of psychological ownership will be a mediator between job security and turnover intention as well as innovative behavior in the organization. To accomplish these purposes, a model was built among job security as predictor variable, the psychological ownership as mediating variable and turnover intention, and innovative behavior as criteria variables based on the studies conducted in the various areas. The 248 questionnaires surveyed from the area of DaeGu and Kyungbuk were used in the statistical analyses. The detail statistical techniques are such as descriptive analysis, reliability analysis, factor analysis, correlation analysis, and multi regression analysis. The results of the study show that job security had positively significant effect on turnover intention and innovative behavior. In addition, only the psychological ownership of organization-level thinking have partial mediating effects between job security and innovative behavior also job security and turnover intention. The results may indicate that the psychological ownership of organization-level thinking be a key factor to alleviate the turnover intention of employees and to encourage the innovative behavior during their works for the small-medium size companies showing the unstable job security.

고성과작업시스템(HPWS)은 공동체적인 가치와 철학에서 출발하여 종업원의 역량을 지속적으로 개발하고 동기를 부여하여 기업의 성과를 높이려는 경영시스템이다. 고용불안정성은 종업원 개인이 현재의 고용상태가 앞으로도 존속할 것인가에 대한 위협 및 우려를 말하며, 해고의 위협을 느끼는 개인뿐만 아니라 해당 조직 수준에서도 고용불안정성은 상당한 영향을 미치고 있다. HPWS가 종업원 개인과 기업 수준의 성과에 긍정적인 영향을 미친다는 연구 및 고용불안정성이 개인

In this study, an accelerated carbonation process was applied to stabilize hazardous heavy metals of industrial solid waste incineration (ISWI) bottom ash and fly ash, and to reduce CO2 emissions. The most commonly used method to stabilize heavy metals is accelerated carbonation using a high water-to-solid ratio including oxidation and carbonation reactions as well as neutralization of the pH, dissolution, and precipitation and sorption. This process has been recognized as having a significant effect on the leaching of heavy metals in alkaline materials such as ISWI ash. The accelerated carbonation process with CO2 absorption was investigated to confirm the leaching behavior of heavy metals contained in ISWI ash including fly and bottom ash. Only the temperature of the chamber at atmospheric pressure was varied and the CO2 concentration was kept constant at 99% while the water-to-solid ratio (L/S) was set at 0.3 and 3.0 dm3/kg. In the result, the concentration of leached heavy metals and pH value decreased with increasing carbonation reaction time whereas the bottom ash showed no effect. The mechanism of heavy metal stabilization is supported by two findings during the carbonation reaction. First, the carbonation reaction is sufficient to decrease the pH and to form an insoluble heavy metal-material that contributes to a reduction of the leaching. Second, the adsorbent compound in the bottom ash controls the leaching of heavy metals; the calcite formed by the carbonation reaction has high affinity of heavy metals. In addition, approximately 5 kg/ton and 27 kg/ton CO2 were sequestrated in ISWI bottom ash and fly ash after the carbonation reaction, respectively.
