  • As the development of modern technology, human works shift whose roll from physical conditions to the system monitoring tasks. In this paper, safety-presentation configuration is discussed instead of well-known fault-warning configuration. Safety-presentation configuration is verified as superior to the fault-warning configuration in hazard prevention. The estimation of system states involves the decision making environments which lack of required in formations and most of all the informations are not precise too. And the limitation of human information processing show doubtful results. So the estimation of system states is regardes as fuzzy number, and its operation produces the parameter that explain the discriminability(d), decision criterion ($\beta$) of system operator's behaviors. These two values served as performance indices. Especially the $\beta$ is a good milestone of the operator's altitude degree of caution.

  • We introduce a high-performance named entity recognition (NER) model for written and spoken language. To overcome challenges related to labeled data scarcity and domain shifts, we use transfer learning to leverage our previously developed KorBERT as the base model. We also adopt a meta-pseudo-label method using a teacher/student framework with labeled and unlabeled data. Our model presents two modifications. First, the student model is updated with an average loss from both human- and pseudo-labeled data. Second, the influence of noisy pseudo-labeled data is mitigated by considering feedback scores and updating the teacher model only when below a threshold (0.0005). We achieve the target NER performance in the spoken language domain and improve that in the written language domain by proposing a straightforward rollback method that reverts to the best model based on scarce human-labeled data. Further improvement is achieved by adjusting the label vector weights in the named entity dictionary.

  • Some worker is occupationally exposed to cold and freezing environment. The cold stimuli in the working environment impose physiological and psychological loads on workers to decrease the task performance. The purpose of this study is to investigate the cold stimuli of cold and freezing stores widely used in Busan can make an effect on human's physiological responses and task performance, experimentally and analytically. In the experiment, 5 workers are selected as subjects, and then their skin temperatures of hand and ear, heart rates, blood pressure, and ring test performances in cold($3^{\circ}C$) and freezing($-22^{\circ}C$) stores were measured for 21 minutes and analyzed by using statistical method. It is observed that a physiological variation and the task performance are significantly influenced by an exposure time as well as a strength of cold stimuli. Also, it is suggested the exposure limiting times for the useful manual work and the performance predict model of the ring tasks. The result of this study will be useful for a fundamental data of which design the standard task time of manual tasks and solve the job placement problem of worker selection and placement in cold environment.

  • Recently it was reported that Insertion/Deletion polymorphism in the gene coding for Angiotensin-Converting Enzyme (ACE) is associated with human capacity for physical performance. This study was performed to genotyping of the ACE gene to determine the correlation between elite endurance performance and ACE I/D gene polymorphism. DNA sample was obtained from peripheral blood, hair roots and mouth epithelial cell in 739 general population and 200 elite athletic performance students. The ACE gene was amplified by polymerase chain reaction (PCR) using allele specific oligonucleotide primers. 155, 525 bp and 237 bp PCR products indicating the presence of insertion(I) and deletion(D) alleles, respectively, were clearly resolved after electrophoresis on a 2% agarose gel with ethidium bromide. Of the 200 elite athletic performance population subjects, 68(34%) showed ACE genotype 11,100(50%) genotype ID and 32(16%) genotype DD. Of the 739 general population subjects, 259(35.1%) showed ACE genotype 11,363(49.1%) genotype ID and 117(15.8%) genotype DD. Therefore ACE I/D gene polymorphism was not associated with human capacity for physical performance.(p>0.05)

  • BIM is one of the means of reducing the economic loss caused by design errors. These features of BIM have led to increased use of BIM. With the increasing use of BIM, several studies have been conducted to analyze the performance of BIM. As the importance of BIM staff is emphasized in the performance analysis of BIM, the human resource allocation of BIM staff can become an important research issue. However, there are few studies to measure the workforce effectiveness of BIM staff. Ham et al (2020) measured BIM workforce efficiency using FCFS queue model rules. Since design errors can have different effects on the project depending on the type, there are design errors that must be dealt with first. Therefore, in this study, a priority queue was used to solve design errors with high priority first. The performance of BIM-based design verification was analyzed by quantitatively analyzing the performance of BIM staff when the priority rule was applied to the design error processing sequence.

  • Intellectual capital is becoming a crucial factor for a firm's long-term profit and performance in the knowledge-based economy as more firms identify their core competence as invisible assets rather than visible assets (Itami, 1987). The company was encouraged to measure financial and non-financial factors, including the customer perspective groups, the internal business process, learning and growth perspective, then to link all these measurements in a coherent system. This paper seeks to investigate the influence of intellectual capital elements on company performance, as well as the relationship among intellectual capital elements from a cause-effect perspective. Resource-Based View (RBV) considers intellectual capital as resource and capability to sustain competitive advantage on company performance. The partial least squares approach is used to examine listed banks in Indonesia Stock Exchange for year 2017-2019. Results show that human capital directly has positive influences on innovation capital, customer capital, and process capital. Innovation capital has positive, but less significant influence on process capital, which in turn influences customer capital. Human capital and process capital also influence customer capital. Finally, customer capital contributes to performance. This study helps management to identify relevant intellectual capital elements as competitive advantage and their indicators to enhance business performance.

  • This study examines the relationship between three major elements -Transformational leadership, Prosocial Behavioral Intentions, and Organizational Performance of full-time academics from different universities and colleges in Oman. A total of 322 full-time employees from different universities and technical colleges participated in an online survey and hardcopy survey. The data was collected using the primary data collection method. Structured scales were adopted for the study to include all the variables under study (Garcia-Morales et al., 2012; Baumsteiger et al., 2019). The adopted questionnaire was slightly modified to align with the circumstances of universities as well as colleges in Oman. A hypothesis is formed to find out the significant contributions among different sample categories. The correlation method was used to find out the relationship. It was evident from the result that there exists a significant relationship between major variables under study. This study reveals an important characteristic of transformational leadership towards prosocial behavioral intentions as it has a connection with organizational performance. There is limited research available to find out the relationship between prosocial behavioral intentions, transformational leadership, and organizational performance. This research focuses on identifying the antecedents and factors influencing organizations' performance efficiently and productively.
