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.

Underwater explosion properties for TNT, an ideal explosive, and DXD-04, a nonideal explosive, were numerically modeled with a one-dimensional Lagrangian hydrodynamic code. The equation of state parameters for detonation products for TNT and DXD-04 were obtained from the BKW code, assuming complete reaction. Burn of TNT was modeled by using the Chapman-Jouguet(CJ) volume burn technique, a programmed-burn technique, assuming instantaneous detonation reaction. Burn of DXD-04 was modeled by using the same technique and by using the reaction rate calibrated from two-dimensional steady-state detonation experiments. The calculations for TNT reproduced the experimental peak pressure of the shock wave propagating through water with an error of $3.0\%$ and the experimental oscillation period of the bubble formed of detonation products with an error of $2.3\%$. For DXD-04, the CJ volume burn technique could not reproduce the experimental observations. When the reaction rate calibrated from two-dimensional steady-state detonation experimental data, the calculated peak pressure was slightly higher by $7.3\%$ than the experimental data, but the calculated shock profile was in good agreement. The bubble period was reproduced with an error of $1.8\%$. These results demonstrated that underwater explosion properties for an ideal explosive can be predicted by using a programmed burn technique, and that, however, those for a nonideal explosive can be predicted only when a well-calibrated reaction rate is used.

Purpose: The aim of this study was to investigate the degree of stress, resilience, focusing manner, and quality of life among burn rehabilitation patients. Furthermore, it seeks to identify factors affecting the quality of life in this patient group. Methods: The participants of this study were 129 burn patients, aged 19 or older, who received treatment at the rehabilitation of a university hospital in Seoul. Data were collected from June 22 to August 31, 2022 through self-report questionnaires covering stress, resilience, focusing manner and quality of life.The data were analyzed using the SPSS 29.0 program. Results: Multiple regression analysis showed that education level, cause of burn, area of burn, pain, stress, and focusing manner significantly affected the quality of life, explaining 74.5% of the variance. Conclusion: In particular, focusing manner was a major factor affecting the quality of life in burn rehabilitation patients. Therefore, there is a need to develop intervention programs aimed at increasing focusing manner in this patient group.

Purpose: The necrotizing fasciitis is a terrifying infectious disease that can rapidly spreads to surrounding tissues when fascia is infected and it can cause sepsis to death if not properly diagnosed and treated. The purpose of this study is to investigate the characteristics, causes, and treatment methods of necrotizing fasciitis in Korea through reviewing patients admitted to our burn center. Methods: 21 patients with necrotizing fasciitis were selected for this study among those inpatients with electronic medical records (EMR) admitted to Hallym University Hangang Sacred Heart Medical Center from Jan 1, 2008 to June 30, 2019. The medical records and wound photos of those 21 selected subjects were reviewed. Results: There were 13 male and 8 female patients and mean age was 58.76 years old. 13 of 21 subjects were survived and 8 died (38% mortality rate). The surgical treatments performed were I&D, fasciotomy, debridement, allograft, burring, STSG, flap, and amputation. The most common causes were burns in 9 subjects (6 contact burns) and cellulitis occurred on skins in 5 subjects. And other various causes were observed as fournier's gangrene, stab wound, intramuscular injection, tumor and bleu toe syndrome (toe necrosis). The infected areas were 11 feet and legs, 7 hips, 3 abdomen and trunk in 21 subjects. Of the 8 deaths, 3 were infected in feet and legs, 2 were infected in hips, and 2 were infected in abdomen and trunk. As for underlying diseases, 12 patients with hypertension or diabetes were the highest and others such as cancer and stroke were found. Conclusion: The only method to increase the survival rate is to 'suspect' the disease as much as possible and perform early extensive excision. It is advisable to treat the disease by the burn center to properly provide adequate and optimal wound management, infection control, medical care and nutritional supports.

Purpose : The purpose of this study is to identify the degree of occupational therapist's professional ethics and to examine the correlation between professional ethics, job stress, and burnout. It also investigates the effects of the occupational therapist's professional ethics on job stress, and burn out, so that we can find a way to reduce them in occupational therapists. Methods : We conducted surveys from June 1 to July 5, 2022. The general characteristics were examined using a frequency analysis. Professional ethics, job stress, and burn out were examined using descriptive statistics. The correlation among them was analyzed with the Pearson correlation coefficient. To find out what factors affect job stress and burn out, we also conducted a multiple regression analysis. Results : First, professional ethics was averaged at 3.57±.34. Second, a significant negative correlation in professional ethics was found between job stress and burn out (p<.01). As a result of the correlation between occupational ethics sub-factors and job stress and burnout, factors excluding nonleisure and self-reliance showed a statistically significant correlation (p<.01, p<.05). Third, professional ethics sub-factor was affected job stress and burn out (p<.01, p<.05). The sub-factors affecting job stress were hard work (𝛽=.-461, p<.01), delay of gratification (𝛽=.-267, p<.01), and relation with coworker (𝛽=.-245, p<.01) and morality (𝛽=.-165, p<.05); and those influencing burnout were delay of gratification (𝛽=-.240, p<.01), relation with coworker (𝛽=-.223, p<.01), centrality of work (𝛽=-.189, p<.01) and hard work (𝛽=-.184, p<.05). Conclusion : The results of this study confirmed the importance of professional ethics affecting job stress and burn out. Through follow-up research, it will be necessary to develop and apply programs to improve professional ethic of occupational therapists in the future.

In this paper, the problem of determining optimal burn-in time is considered under a general failure model. There are two types of failure in the general failure model. One is Type I failure (minor failure) which can be removed by a minimal repair and the other is Type II failure (catastrophic failure) which can be removed only by a complete repair. In this model, when the unit fails at its age t, Type I failure occurs with probability 1 - p(t) and Type II failure occurs with probability p(t), $0{\leq}p(t)\leq1$. Under the model, the properties of optimal burn-in time maximizing mean time to the catastrophic failure during field operation are obtained. The obtained results are also applied to some illustrative examples.
