This study aims to examine the intermediary roles of employee performance between high performance work system (HPWS) and its operational performance on the resource based view. Taking into account the unit of analysis, this study used a hierarchical linear modeling analysis in order to test rigorously the association between HPWS at the organisational level and employee performance at the individual level. For this empirical test, Human Capital Corporate Panel (HCCP) data including 316 firms and 7,872 respondents (including 923 team leaders) were used. To meet the unit of analysis and test the mediation effect, data at the individual and team level were aggregated into the organisational level. The empirical results show that HPWS have a positive impact on operational performance as well as employee performance such as job satisfaction, organisational commitment and organisational trust. Regarding the mediation effect, job satisfaction and organisational trust mediate between HPWS and operational performance. Theoretical implications are discussed in conclusion.

This study aimed to seek the way of effectively managing job stress of shift work nurses, to improve nursing performance, the influence of job stress of shift work nurses on nursing performance through convergence research. A total of 244 questionnaires obtained by a survey targeting nurses, who were doing shift work in a university hospital located in B city, in the period from March 2 to 15, 2015 were analyzed using the SPSS 21.0 program. As a result, the mean score of job stress was 3.57 points, and the mean score of nursing performance was 3.69 points. Job stress made a significant positive(+) influence on the sub-dimensions of interpersonal duty. Therefore, efforts should be made to more accurately identify shift work nurses' job stress and efficiently manage the nursing personnel. Moreover, if shift work nurses' job stress is effectively managed by preparing practical job stress management intervention programs for continuous improvement of nursing performance, high quality medical services will be provided through high quality nursing practice.

Noise, dust, etc. caused by road pavement cutting work, which frequently occurs in new construction or reconstruction of buildings, construction of complexes, etc., are environmental hazards and cause civil complaints. Recently, an eco-friendly pavement cutter is being developed to make the work low in noise and dust, however, the on-site cutting performance of the equipment has not been quantified. In this study, in order to derive a standard value for comparing the cutting performance of the eco-friendly cutter under development, a conventional pavement cutter was applied to four residential sites in Seoul and Gyeonggi-do, and the cutting data was collected. As a result of analyzing the collected data, the conventional pavement cutter showed a cutting performance of 12.3 to 20.2 sec/m, and the average was 27.2 sec/m. In the future, additional cutting experiments with various mixing ratios, materials, and depths are planned to confirm the performance of conventional pavement cutter in more detail.

This study aimed to verify the positive effect of work meaningfulness(WM) on flourishing(FL) with the successive positive effects of work engagement(WE) and job performance(JP) as dual mediators. We conducted an online survey of 395 incumbents working in the companies of different types and statistically analyzed data using SPSS and SPSS Process macro for hierarchical regression and bootstrapping. The results are as follows: 1. correlation coefficients of all combinations from four variables are significant, 2. simple mediation effects(WM-WE-FL and WE-JP-FL) are significant, 3. dual mediation effet(WM-WE-JP-FL) is verified. This study showed practical guide for the efficient management of employees in recent autonomous work environment and further studies with longitudinal method will be needed in order to verify substantially the dual mediation.

Commercial conductive metal inks are available, but metals used in these have unsuitable work function for efficient OLED device performance. Metals with low work function tend to oxidize easily, which makes it challenging to develop low work function metal inks. In this research we describe printed low work function Al cathode.

Recently, High accuracy and precision are required in various industrial field especially, semiconductor manufacturing apparatus, Ultra precision positioning apparatus, Information field and so on. Positioning technology is a very important one among them. Is such technology has been rapidly developed, this field needs the positioning accuracy as high as submicron. It is expected that the accuracy of 10nm and 1nm is required in precision work and ultra precision work field, respectively by the beginning of 2000s. High speed and low vibration are also needed. This work deals with the design method and control system of Ultra precision positioning apparatus. We will examine the control performance and stability before manufacturing the real apparatus by using MATLAB SIMULINK based or pre-designed controller and system modeling.

Actoprotectors are preparations that increase the mental performance and enhance body stability against physical loads without increasing oxygen consumption. Actoprotectors are regarded as a subclass of adaptogens that hold a significant capacity to increase physical performance. The focus of this article is studying adaptogen herbs of genus Panax (P. ginseng in particular) and their capabilities as actoprotectors. Some animal experiments and human studies about actoprotective properties of genus Panax attest that P. ginseng (administered as an extract) significantly increased the physical and intellectual work capacities, and the data provided suggests that ginseng is a natural source of actoprotectors. Preparations of ginseng can be regarded as potential actoprotectors which give way to further research of its influence on physical and mental work capacity, endurance and restoration after exhaustive physical loads while compared with reference actoprotectors.

Today many firms rely on information systems planning (ISP) to remain competitive by transforming their business model and redesigning their IT architecture. In spite of some great success stories, many firms are having a lot of difficulty with ISP. Previous research has found a number of critical factors for ISP. However, these studies have focused mainly on organizational characteristics. In contrast, our study has taken into consideration organizational work and planning process as main critical factors for ISP performance. Empirical results indicate that the ISP performance has a stronger relationship with ISP planning process rather than organizational work characteristics.

The purpose of this study is to investigate the factors affecting innovation capability and innovation performance of midsize company entering overseas market. More specifically, in terms of managerial, organizational, and employee - level factors, we set leadership, operating system, and taking charge at work as variables influencing innovation capability and tried to understand the effect of innovation capability on innovation performance through empirical studies. In addition, we examined the differences in the influence factors on innovation capability and the effect on innovation performance in the home country and overseas countries. As a result of the empirical analysis, all of the influence factors had a positive effect on the innovation capability and the innovation capability had a positive effect on the innovation performance. The degree of influence was in the order of operating system, leadership and taking charge at work. In China, there is no significant difference in the order of operating system, leadership and taking charge at work. In the case of Korea, operating system and leadership have a positive effect, but the employee's taking charge at work does not affect innovation capability. The results of this study are as follows. First, it is necessary to enhance innovation capability in accordance with local characteristics. In Korea, there are additional activities to induce employee's taking charge at work is required for improved innovation capability and innovation performance.
