중국 직장에서는 소위 '신형 야간근무'라 불리는 WeChat이나 QQ와 같은 SNS를 사용한 업무전달이 보편화되는 있다. 본 연구는 업무시간 외 SNS를 통한 업무전달이 직무성과에 미치는 영향을 실증분석하는 것이다. 중국 직장인 310명을 대상으로 설문조사 하여 가설들을 검증하기 위해 구조방정식모형분석을 활용하였다. 분석결과, 근무시간 외에 SNS를 통해 빈번하게 업무전달 연락을 받게 되면 직무스트레스가 커지고, 일-가정 간 갈등을 심화시켜 업무에 대한 열정을 감소시켜 그 결과 직무성과 마저 저하되는 것으로 나타났다. 본 연구는 업무시간 외 SNS 활용이 직무성과에 긍정적인 효과를 가져온다는 기존연구결과와는 다른 견해를 제공해 관련 이론정립에 시사점을 제공한다. 또한 향후 연구에서는 이러한 상반된 견해를 융합하는데 조절효과의 영향에 대한 분석이 필요할 것이다.

The purpose of the study was to examine job satisfaction, work performance, work satisfaction, perceived needs and self-evaluation of knowledge and skills of nutrition teachers. Survey questionnaire was administered to 106 nutrition teachers in schools of Gyeonggi area. Subjects were categorized into high- or low-job satisfaction group, and study variables were examined by job satisfaction group. Overall job satisfaction was high, with a mean score of 14.9 out of 20. High-job satisfaction group had more favorable perception regarding human relations and workplace atmosphere compared to the counterparts (p < 0.001). Work performance, examined by 12 items, was not significantly different between the two groups. However, satisfaction regarding specific work of nutrition teachers was significantly different by job satisfaction (p < 0.001). High-job satisfaction group responded that they had more knowledge and skills in areas such as food purchase management, food sanitation and safety management, equipment and facility management, nutrition education, nutrition counseling (p < 0.01), and general management & marketing (p < 0.05). High-job satisfaction group also indicated that nutrition teachers need to have more knowledge and skills than the counterparts, regarding food purchase management (p < 0.001), nutrition education (p < 0.01), nutrition counseling, general management and marketing, and teaching practices (p < 0.05). In addition, study results showed significant positive correlations among study variables. This study suggested that job satisfaction of nutrition teachers might be increased by having favorable human relations and workplace atmosphere, increasing satisfaction with specific work of nutrition teachers, and by increasing the knowledge and skills required for the work of nutrition teachers.

The purpose of this study is to demonstrate the antecedent and consequential factors of satisfaction with the flexible working system. Organizational culture was examined as an antecedent factor, while job satisfaction, work performance, organizational commitment, turnover intention, and quality of life were examined as outcome factors. The data of 2,785 public officials who used the flexible work system in the Korea Institute of Public Administration (2022) data set were analyzed using SPSS 28.0. and PROCESS macro's Model 4. The main research findings are as follows. First, organizational cultures that respect individuality and cooperation, supports management, and aims for work autonomy all positively and significantly affect satisfaction with the flexible working system. When ranking the size of influence by the type of organizational culture, work autonomy, respect for individuality, and a cooperative organizational culture had a positive impact in that order, with work autonomy being the most influential factor. In addition, the public officials' age, job preparation period, self-evaluation of workload, and overtime working hours are significant antecedents of satisfaction with the flexible work system. Second, when examining consequential factors, a high level of satisfaction with the flexible working system affects job satisfaction (+), work performance (+), organizational commitment (+), turnover intention (-), and quality of life (+). Job satisfaction was an especially valid mediator between satisfaction with the flexible working system and other consequential factors, including work performance, organizational commitment, turnover intention, and quality of life.

The work posture impose additional stress upon human workers so that it should be carefully considered in designing works. However, we have a lot of manufacturing plants which convert their standing workplace to sedentary one. To confirm the validity of that trend, the authors conducted an experimental study, and compared the results. The results of the EMG and the self-cognitive symptoms, in general, showed a correspondent trend that the sedentary work posture was rated more comfortable. At the beginning of the work, complaint of the lowerback was higher whereas that of the lower leg and the feet went higher as the time elapsed. If the weight of workpiece were heavier than 500g, increasing rate of bodily discomfort in the sedentary posture were greater than that of the standing posture. In the meanwhile, the standing posture was consistently superior to the sedentary posture in its performance. Thus, in conclusion, for a light assembly work, sedentary work posture would be recommendable because bodily discomfort would be larger irrespective of the small increase of performance increase.

We have controlled the graphene surface in two ways to improve the device performance of optoelectronics based on graphene transparent conductive films. We controlled multilayer graphene (MLG) work function and localized surface plasmon resonance wavelength using a silver nanoparticles formed on graphene surface. Graphene substrates were prepared using a chemical vapor deposition and transfer process. Various size of silver nanoparticles were prepared using a thermal evaporator and post annealing process on graphene surface. Silver nanoparticles were confirmed by using scanning electron microscopy (SEM). Work functions of graphene surface with various sizes of Ag nanoparticles were measured using ultraviolet photoelectron spectroscopy (UPS). The result shows that the work functions of MLG could be controlled from 4.39 eV to 4.55 eV by coating different amounts of silver nanoparticles while minimal changes in the sheet resistance and transmittance. Also the Localized surface plasmon resonance (LSPR) wavelength was investigated according to various sizes of silver nanoparticles. LSPR wavelength was measured using the absorbance spectrum, and we confirmed that the resonance wavelength could be controlled from 396nm to 425nm according to the size of silver nanoparticles on graphene surface. To confirm improvement of the device performance, we fabricated the organic solar cell based on MLG electrode. The results show that the work function and plasmon resonance wavelength could be controlled to improve the performance of optoelectronics device.

We use both theoretical analysis and simulations to study the impact of crosspoint-queued (CQ) buffer size on CQ switch throughput and delay performance under different traffic models, input loads, and scheduling algorithms. In this paper, we present the following. 1) We prove the stability of CQ switch using any work-conserving scheduling algorithm. 2) We present an exact closed-form formula for the CQ switch throughput and a non-closed-form but convergent formula for its delay using static non-work-conserving random scheduling algorithms with any given buffer size under independent Bernoulli traffic. 3) We show that the above results can serve as a conservative guide on deciding the required buffer size in pure CQ switches using work-conserving algorithms such as the random scheduling, under independent Bernoulli traffic. 4) Furthermore, our simulation results under real-trace traffic show that simple round-robin and random work-conserving algorithms can achieve quite good throughput and delay performance with a feasible crosspoint buffer size. Our work reveals the impact of buffer size on the CQ switch performance and provides a theoretical guide on designing the buffer size in pure CQ switch, which is an important step toward building ultra-high-speed switch fabrics.
