Objectives: The purpose of this study is to explore the developmental direction of the hospital management field that contributes to the academic and practical development of the health care industry and to establish its identity by using the Korean Journal of Health Service Management. Methods: A total of 156 papers were analyzed from April 2007 to December 2018. Frequency analysis and descriptive statistics were performed using SPSS 25.0. Results: The volume of articles published in the hospital management field was decreasing and the ratio was relatively low due to the nature of the journal. The disposition of the papers in the hospital management field excessively focused on the organizational behavior field, and research in the management field that was difficult to access was decreasing. In addition, about 83% of the participants were drawn from hospitals. Conclusions: It is necessary to present guidelines for publication of theses so that a managerial approach can be made rather than an approach to industrial psychological theory verification.

Purpose: This study aims to determine the relation among job stress, self-esteem, resilience, and field adaptation of the newly graduated nurses, through which an effective mediation strategy toward field adaptation and basic data on improving nursing quality can be established. Methods: The subjects were 110 newly graduated nurses who have worked at a tertiary hospital and a general hospital for less than 12 months. The data were collected, using self-reported questionnaires, from July 9 to July 31, 2018, and were analyzed by descriptive statistics, t-test, one-way ANOVA, $Scheff{\acute{e}}$ test, Pearson's correlation coefficient and stepwise multiple regression using an SPSS/WIN 24.0 program. Results: The study result showed that the newly graduated nurses' job stress, resilience, job satisfaction, and desired department influenced their field adaptation, explaining 60.2% of the variance in the field adaptation (F=42.14, p<.001). The nurses' job stress had the biggest influence on their field adaptation, explaining 38.7% of the variance. Conclusion: Human resource management strategy considering those influencing factors may improve the filed adaptation of newly graduated nurses and help them to retain in their work field.

Background: The objective of this study was to demonstrate the safety, efficacy, and feasibility of intraoperative monitoring of the recurrent laryngeal nerves during thoracoscopic and robotic 3-field esophagectomy. Methods: This retrospective analysis details our initial experience using intraoperative nerve monitoring (IONM) during minimally invasive 3-field esophagectomy. Data were obtained from a prospectively maintained database and electronic medical records. The study included all patients who underwent minimally invasive (video-assisted thoracic surgery/robotic) transthoracic esophagectomy with neck anastomosis. The patients were divided into those who underwent IONM during the study period and a historical cohort who underwent 3-field esophagectomy without IONM at the same institution. Appropriate statistical tests were used to compare the 2 groups. Results: Twenty-four patients underwent nerve monitoring during minimally invasive 3-field esophagectomy. Of these, 15 patients underwent thoraco-laparoscopic operation, while 9 received a robot-assisted procedure. In the immediate postoperative period, 8 of 24 patients (33.3%) experienced vocal cord paralysis. Relative to a historical cohort from the same institution, who were treated with surgery without nerve monitoring in the preceding 5 years, a 26% reduction was observed in the nerve paralysis rate (p=0.08). On follow-up, 6 of the 8 patients with vocal cord paralysis reported a return to normal vocal function. Additionally, patients who underwent IONM exhibited a higher nodal yield and a decreased frequency of tracheostomy and bronchoscopy. Conclusion: The use of IONM during minimally invasive 3-field esophagectomy is safe and feasible. This technique has the potential to decrease the incidence of recurrent nerve palsy and increase nodal yield.

Background: To explore the effect of radiation on metastatic lymph nodes (LNs) after neoadjuvant chemoradiation therapy (nCRT), we examined the metastatic features of LNs according to their inclusion in the radiation field. Methods: The patient group included 88 men and 2 women, with a mean age of $61.1{\pm}8.1$ years, who underwent esophagectomy and lymphadenectomy after nCRT. Dissected LNs were compared in terms of clinical suspicion of metastasis, nodal station, and inclusion in the radiation field. Results: LN positivity did not differ between LNs that were inside (in-field [IF]) and outside (out-field [OF]) of the radiation field (IF: 40 of 465 [9%], OF: 40 of 420 [10%]; p=0.313). In clinical N+ nodal stations, IF stations had a lower incidence of metastasis than OF stations (IF/cN+: 16 of 142 [11%], OF/cN+: 9/30 [30%]; p=0.010). However, in clinical N- nodal stations, pathological positivity was not affected by whether the nodal stations were included in the radiation field (IF/cN-: 24 of 323 [7%], OF/cN-: 31 of 390 [8%]; p=0.447). Conclusion: Radiation therapy for nCRT could downstage clinically suspected nodal metastasis. However, such therapy was ineffective when used to treat nodes that were not suspicious for metastasis. Because significant numbers of residual metastases were identified irrespective of coverage by the radiation field, lymphadenectomy should be performed to ensure complete removal of residual nodal metastases after nCRT.

Purpose: This study aimed to provide basic data for infection control education plans based on infection control awareness and performance of paramedic students during clinical field training. Methods: Data were collected from paramedic students with experience in clinical field training. The data collection period was from May 4, 2023, to June 4, 2023, and 132 copies of the collected survey were analyzed using the SPSS27.0 program. Results: Infection control awareness and performance were 4.80±0.24 points and 4.49±0.55 points out of 5, respectively. The infection control awareness of the participants according to clinical field training-related characteristics differed significantly in university education before clinical field training (t=2.100, p=.038). In addition, there were significant differences in performance in the number of clinical field training sessions (F=9.149, p=.000), hospital education before clinical field training (t=5.365, p=.000), and hospital education during clinical field training (t=3.094, p=.002). Conclusion: Before clinical field training, schools should provide infection control education that combines theory and practice suitable for hospital practice so that students can complete the infection control education organized by the hospital. Furthermore, if a university develops infection control in the clinical field training guidelines, it will have a positive impact on students' infection control performance through prior education.

Objective : We evaluated a modified trans-middle temporal gyrus (MTG) approach with good postoperative visual preservation for patients with trigonal tumors. Methods : Three patients with a trigonal tumor were treated via the modified trans-MTG approach guided by a neuro-navigator. Modified trans-MTG approach involve the incision at the MTG within 5 mm to the superior temporal sulcus. This approach makes a proper trajectory to the trigone but also reduces the retraction injury of MTG as little as possible to prevent postoperative visual field defect. Preoperative and postoperative visual field examination using perimetry was performed to evaluate the visual field. Results : Three patients underwent surgery for lymphoma in the right trigone, meningioma in the left trigone, and focal enhancing nodule in the right paratrigonal area, respectively. In case of lymphoma, preoperative examination showed a left homonymous hemianopsia : one week later after surgery, a visual field examination was performed and revealed improvement of the visual field defect. In case of the meningioma, the preoperative examination showed no visual field defect : one month later, the visual field had no defect. In case of the enhancing nodule, preoperative visual field testing revealed a partial left homonymous hemianopsia. Visual examination within one month after surgery showed no visual field defect. All three patients treated with the modified trans-MTG approach showed no visual deterioration after surgery. Conclusion : The modified trans-MTG approach provides a safe and useful technique for trigonal tumors without postoperative visual field deterioration and affords adequate exposure of the trigonal tumor with a short trajectory.

Purpose: To report the results of dosimetric comparison between intensity-modulated radiotherapy (IMRT) using Tomotherapy and four-box field conformal radiotherapy (CRT) for pelvic irradiation of locally advanced rectal cancer. Materials and Methods: Twelve patients with locally advanced rectal cancer who received a short course preoperative chemoradiotherapy (25 Gy in 5 fractions) on the pelvis using Tomotherapy, between July 2010 and December 2010, were selected. Using their simulation computed tomography scans, Tomotherapy and four-box field CRT plans with the same dose schedule were evaluated, and dosimetric parameters of the two plans were compared. For the comparison of target coverage, we analyzed the mean dose, $V_{nGy}$, $D_{min}$, $D_{max}$, radical dose homogeneity index (rDHI), and radiation conformity index (RCI). For the comparison of organs at risk (OAR), we analyzed the mean dose. Results: Tomotherapy showed a significantly higher mean target dose than four-box field CRT (p = 0.001). But, $V_{26.25Gy}$ and $V_{27.5Gy}$ were not significantly different between the two modalities. Tomotherapy showed higher $D_{max}$ and lower $D_{min}$. The Tomotherapy plan had a lower rDHI than four-box field CRT (p = 0.000). Tomotherapy showed better RCI than four-box field CRT (p = 0.007). For OAR, the mean irradiated dose was significantly lower in Tomotherapy than four-box field CRT. Conclusion: In locally advanced rectal cancer, Tomotherapy delivers a higher conformal radiation dose to the target and reduces the irradiated dose to OAR than four-box field CRT.

As a result of analyzing problems in field practice and its effects, the following conclusions can be obtained. Man students were more satisfied with their choice of this department than woman students and woman students recognized the importance of hospital practice although they felt the need of fire fighting station practice and man students felt the necessity of hospital practice, but they answered the fire fighting station practice was important. Departments of field practice are emergency and nurse departments in hospitals and emergency aid section in fire fighting stations. And it is found that field practice was performed well in relation to major subject. Areas of practice included emergency room, operation room and extensive cure unit and the experience of ambulance was more in fire fighting station than in hospital. Clinical guidance of professor was preferred to once a week and the students answered they felt satisfaction with practice through conference. Answer that field practice was helpful in understanding class was very high as 96.8% and its connection with employment was low as 12.8%. It is found that a proper timing of field practice was winter vacation for hospital practice after completing the second semester of the first year and summer vacation for fire fighting station practice after the first semester of the second year. The most difficult department in field practice was nurse department in hospital because 'respondents were practice students' and administrative department in fire fighting stations because 'they lacked recognition of paramedic'. In making practice diary, 'describing measure results' was difficult most and the respondents wanted to keep the diary in their custody.

Purpose: The purpose of this study is to identify the effects of a standardized educational program to improve nursing competency on newly graduated nurses in a children's hospital after developing and applying a pediatric nurse education program. The effectiveness of the program was confirmed by evaluating the clinical competency and field adaptation. Methods: In the first step, an education program was developed using the analysis, design, development, implementation and evaluation (ADDIE) model. As a second step, a similar experimental study of a single group repeat measures design was conducted to evaluate the clinical competency and field adaptation over time after application of the program. Additionally, a focus group interviews were conducted to collect subjective data on the effects and improvement points of the program. Results: As a result of applying the program, there was a significant change in the clinical competence and the field adaptation of newly graduated nurses in a children's hospital. The categories derived from the focus group interviews were "getting special guidance," "better care," "becoming a nurse at a children's hospital" and "winning together." Conclusion: It was confirmed that the education program enhances the clinical competency of new nurses in children's hospitals. In addition, it provided the necessary data to understand the experiences of new nurses, help them adapt effectively, and establish appropriate interventions.
