Purpose : The purpose of this study was to identify the degree of occupational therapists' professional identity and examine the correlation between empowerment and burn out. We also investigated the effects of the occupational therapists' professional identity on empowerment and burn out. Through these assessments, we aimed to highlight the importance of professional identity and find methods to improve empowerment and reduce burn out in occupational therapists. Methods : The study was conducted from October 19 to from November 11, 2023. General characteristics, professional identity, empowerment, and burn out were examined using frequency analysis and descriptive statistics. The correlation between these factors was analyzed using Pearson's correlation coefficient. Multiple regression analysis was used to identify factors influencing empowerment and burn out. An α value =.05 was used to verify statistical significance. Results : First, Professional identity was an average 3.24±.37. Second, a significant correlation was found between professional identity and empowerment (r=.417, p<.01) and burn out (r=-.377, p<.01). As a result of the relationship between professional identity sub-factors and empowerment in professional organization (r=.270, p<.01),, belief in self-regulation (r=.258, p<.01), vocational consciousness (r=.348, p<.01), and belief in autonomy (r=.308, p<.01) showed a statistically significant correlation. Professional identity sub-factors were significantly correlated with burnout, professional organization (r=-.199, p<.05), belief in public service (r=-.153, p<.05), belief in self-regulation (r=-.334, p<.01), vocational consciousness (r=-.250, p<.01), and belief in autonomy (r=-.293, p<.01) showed a significant correlation. Third, professional identity sub-factors influencing empowerment were vocational consciousness (β=.154, p<.05) and belief in autonomy (β=.135, p<.05), and those influencing burnout were belief in self-regulation (β=-.389, p<.01) and belief in autonomy (β=-.244, p<.01). Conclusion : The study findings demonstrated that professional identity affects empowerment and burn out. Therefore, continuous study on the professional identity of occupational therapists is warranted.

This study conducted a survey on 414 industrial organization food service workers in the Kyungnam area to find out the effect relationship of the job characteristics of organization food service workers and its effects on job commitment and job satisfaction by recognizing the need for job application through the job characteristic model, which was the beginning of the intrinsic motivation theory for the job of organization food service workers. To accomplish the purpose of this study, the method to analyze the survey was undertaken by using the SPSS 23.0 and Amos 21.0 statistic package program via a data coding process for collected data processing. We can confirm from the analysis results that there is a statistically significant causal relationship in all factors, except task identity, which is a sub factor of job characteristic. This result reaffirms the results of previous research by showing that the worker must be allowed to ensure completion of the entire job when performing the job as the job itself is not one part of the processes. Decision-making autonomy must be given in the work process when the worker performs their job in order to raise job satisfaction and furthermore to increase job commitment. The limitation of this study is that there are limits that making generalization as the study was conducted on industrial organization food service workers in the Kyungnam area as extracted samples.

Although many models have been proposed to accurately predict the response of drugs in cell lines recent years, understanding the genome related to drug response is also the key for completing oncology precision medicine. In this paper, based on the cancer cell line gene expression and the drug response data, we established a reliable and accurate drug response prediction model and found predictor genes for some drugs of interest. To this end, we first performed pre-selection of genes based on the Pearson correlation coefficient and then used ElasticNet regression model for drug response prediction and fine gene selection. To find more reliable set of predictor genes, we performed regression twice for each drug, one with IC₅₀ and the other with area under the curve (AUC) (or activity area). For the 12 drugs we tested, the predictive performance in terms of Pearson correlation coefficient exceeded 0.6 and the highest one was 17-AAG for which Pearson correlation coefficient was 0.811 for IC₅₀ and 0.81 for AUC. We identify common predictor genes for IC₅₀ and AUC, with which the performance was similar to those with genes separately found for IC₅₀ and AUC, but with much smaller number of predictor genes. By using only common predictor genes, the highest performance was AZD6244 (0.8016 for IC₅₀, 0.7945 for AUC) with 321 predictor genes.

The adsorption behaviour of Se(-II) onto granite and MX-80 bentonite in Ca-Na-Cl solutions has been studied utilizing adsorption experiments and surface complexation modelling. Adsorption kinetic experiments allude to steady-state adsorption periods after 7 days for granite and 14 days for MX-80 bentonite. Batch adsorption experiments were carried out to determine the influence that the physicochemical solution properties would have on Se(-II) adsorption behaviour. Adsorption of Se(-II) onto granite and MX-80 bentonite follows the trend of anionic adsorption, with a decrease in R_d values as the solution pH increased. There is also an ionic strength influence on the adsorption of Se(-II) onto granite with a decrease in the R_d value as the ionic strength increased. This effect is not found when observing Se(-II) adsorption onto MX-80 bentonite. Final experiments with a representative groundwater, determined that the adsorption of Se(-II) onto granite and MX-80 bentonite returned R_d values of (1.80 ± 0.10) m³·kg^-1 and (0.47 ± 0.38) m³·kg^-1, respectively. In support of the experiments, a surface complexation modelling approach has been employed to simulate the adsorption of Se(-II) onto granite and MX-80 bentonite, where it was determined that two different surface complexes, ≡S_Se^- and ≡SOH₂⁺_H₂ were capable of simulating Se(-II) adsorption behaviour.

The Korea Meteorological Administration/National Institute of Meteorological Sciences (KMA/NIMS) has monitored atmospheric CO₂ at Anmyeondo (AMY) World Meteorological Organization (WMO) Global Atmosphere Watch Programme (GAW) regional station since 1999, and expanded its observations at Jeju Gosan Suwolbong station (JGS) in the South and at Ulleungdo-Dokdo stations in the East (ULD and DOK) since 2012. Due to a recent WMO CO₂ scale update and a new filter (NIMS) to select baseline levels at each station, the 22 years of CO₂ data are recalculated. After correction for the new CO₂ scale, we confirmed that those corrected records are reasonable within the compatibility goal (±0.1 ppm of CO₂) between KMA/NIMS and National Oceanic and Atmosphereic Administration (NOAA) flask-air measurements with the new scale. With the new NIMS filter, CO₂ baseline levels are now more representative of the large-scale background compared to previous values, which contained large CO₂ enhancements. Atmospheric CO₂ observed in South Korea is 4 to 8 ppm greater than the global average while the amplitude of seasonal variation is similar (10~13 ppm) to the amplitude averaged over a comparable latitude zone (30°N-60°N). Variations in CO₂ growth rate are also similar, increasing and decreasing similar to global values, as it reflects the net balance between terrestrial respiration and photosynthesis. In 2020, atmospheric CO₂ continued increasing despite the COVID-19 pandemic. Even though fossil emission was reduced (around -7% globally), we still emitted large amounts of anthropogenic CO₂. Overall, since CO₂ has large natural variations and its source was derived from not only fossil fuel but also biomass burning, the small fossil emission reduction could not affect the atmospheric level directly.

Technological systems are defined as network(s) consisting of technological infrastructure, industrial organization, and institutional infrastructure. This paper reviews SEMATECH in the U.S. and VLSI Program in Korea as a technological system for semiconductor, which is an advanced technology. Several issues are addressed : how did they get started\ulcorner ; how have they been evolved\ulcorner ; how have the actors and institutions within the system interacted\ulcorner ; what role has the government played in that process\ulcorner Both systems were created by their government, respectively, and they have been evaluated as successful. However, while SEMATECH became complete eough in terms of technological infrastructure, industrial organization, and institutional infrastructure to generate sufficient increasing returns to develop in a self-reinforcing way, a series of VLSI program in Korea is still operated discontinuously under the government subsidy. SEMATECH is more flexible and stable than Korea's VLSI program in that the system has a centralized structure and has been managed and staffed by industry substantially. In addition, both cases show that a technological system may evolve having connections with foreign technological systems and local sub-systems beyond nations, regions and industries. Many other similarities, contrasts, and insights for technological policy from each country's experiences are presented.

This work proposes a neural network approach to solve vehicle routing problems which have diverse application areas such as vehicle routing and robot programming. In solving these problems, classical mathematical approaches have many difficulties. In particular, it is almost impossible to implement a real-time vehicle routing with multiple vehicles. Recently, many researchers proposed methods to overcome the limitation by adopting heuristic algorithms, genetic algorithms, neural network techniques and others. The most basic model for path planning is the Travelling Salesman Problem(TSP) for a minimum distance path. We extend this for a problem with dynamic upcoming of new positions with multiple vehicles. In this paper, we propose an algorithm based on SOM(Self-Organization Map) to obtain a sub-optimal solution for a real-time vehicle routing problem. We develope a model of a generalized multiple TSP and suggest and efficient solving procedure.
