In recent years, the labor consciousness is gradually valued. During the process of pursuing sustainable operation, the enterprises treat occupational hazard risk as the waste of cost. The purpose of OHSAS 18000 occupational security and health management system is to systematically establish the business managerial measures in terms of occupational security and calamity prevention. This research proceeded with questionnaire analysis with respect to the relationship between the OHSAS 18000 system implementation and competitiveness in Taiwan's industries. The research result revealed that there was significant relationship between Taiwan firms' execution of OHSAS 18000 system and industry competitiveness. Thus, the enterprises can decide the proper managerial plans according to the result of their own risk evaluation to prevent the happening of accidents and reduce the operational cost. They can thus completely control business occupational hazard risk through "systematic" management.

Digital technology enhanced the improvement of technological aspects in the both broadcasting and telecommunications industries. The infrastructures of each industry converged to one, which impacts not only on technology but also on the broadcasting service. The current broadcasting service is characterized by one-way service, but it'll changed to be customized, or two-way service that reflects the interest of customers. This change requires a new standard to categorize and analyze the future broadcasting service converged and market structure, differing from the present standard based on the transmission channels. This study aims at forecasting the demand of interactive TV service as a representative broadcasting service in the near future, and analyzing the market structure of the broadcasting services. We assume that the present broadcasting and information and telecommunications services such as terrestrial, cable TV, satellite, digital TV services and high-speed broadband service have strong relationship with interactive TV service. First we use Bass diffusion method to predict the diffusion curve of the present five services. Then we analyze the relationship between the present services and interactive TV service by Delphi method. Finally we estimate the potential subscription number of interactive TV service based on the relationship among the services and diffusion parameters.

The relationship the between electrical properties and surface roughness (Ra) of a wet-etched silicon wafer were studied. Ra was measured by an alpha-step process and atomic force microscopy (AFM) while varying the measuring range $10{\times}10$, $40{\times}40$, and $1000{\times}1000{\mu}m$. The resistivity was measured by assessing the surface resistance using a four-point probe method. The relationship between the resistivity and Ra was explained in terms of the surface roughness. The minimum error value between the experimental and theoretical resistivities was 4.23% when the Ra was in a range of $10{\times}10{\mu}m$ according to AFM measurement. The maximum error value was 14.09% when the Ra was in a range of $40{\times}40{\mu}m$ according to AFM measurement. Thus, the resistivity could be estimated when the Ra was in a narrow range.

The electrochemical chlorine evolution reaction (CER) is an important electrochemical reaction and has been widely used in chlor-alkali electrolysis, on-site generation of ClO^-, and Cl₂-mediated electrosynthesis. Although precious metal-based mixed metal oxides (MMOs) have been used as CER catalysts for more than half a century, they intrinsically suffer from a selectivity problem between the CER and parasitic oxygen evolution reaction (OER). Hence, the design of selective CER electrocatalysts is critically important. In this review, we provide an overview of the fundamental issues related to the electrocatalysis of the CER and design strategies for selective CER electrocatalysts. We present experimental and theoretical methods for assessing the active sites of MMO catalysts and the origin of the scaling relationship between the CER and the OER. We discuss kinetic analysis methods to understand the kinetics and mechanisms of CER. Next, we summarize the design strategies for new CER electrocatalysts that can enhance the reactivity of MMO-based catalysts and overcome their scaling relationship, which include the doping of MMO catalysts with foreign metals and the development of non-precious metal-based catalysts and atomically dispersed metal catalysts.

The impact of raindrops on the soil surface causes soil detachment, which may be estimated by measuring the kinetic energy (KE) of the raindrops. Since direct measurements of rainfall force on ground surfaces are not generally available, empirical equations are an alternative option to estimate KE from rainfall intensity (I), which has the greatest influence over soil erosion and is easily accessible. Establishing the optimal formulation for the relationship between kinetic energy and rainfall intensity has proven to be difficult. Thus, this research considered thirty-seven rainfall events observed from June 2020 to December 2021 using a laster optical disdrometer erected in Kyungpook National University to examine the characteristics of KE-I relationships. We concentrated our discussion on the formation of two different expressions of the KE, including KE expenditure (KE_exp) and KE content (KE_con). The following conclusions were drawn: (1) We employed statistical analysis to demonstrate that the KE_exp is more suitable expression for establishing an empirical rule between KE and I than the KE_con. (2) A power-law model was used to find the best correlation between KE_exp-I relationship, whereas the best match between KE_con and I were found using an exponential equation.

This study attempted to reveal the influence of the exchange relationship (TMX) between Pilates leaders and members on job performance. Accordingly, from April 1 to July 12, 2023, 82 lines of couple data (164 people: 82 leaders, 82 members) were sampled and the following results were derived. First, the higher the leader exchange relationship, the higher the leader's job performance, and the higher the member exchange relationship, the higher the leader's job performance. Second, it can be seen that the higher the leader exchange relationship, the higher the member's job performance, and the higher the member exchange relationship, the higher the member's job performance. Therefore, it can be seen as a result of reflecting the systematic demand for exchange activities because the dependent relationship leads to active job participation through mutual relationships with colleagues.
