Objective: To assess the feasibility and reproducibility of pancreatic surface lobularity (PSL) quantification derived from abdominal computed tomography (CT) in a population of patients free from pancreatic disease. Materials and Methods: This retrospective study included 265 patients free from pancreatic disease who underwent contrast-enhanced abdominal CT between 2017 and 2019. A maximum of 11 individual PSL measurements were performed by two abdominal radiologists (head [5 measurements], body, and tail [3 measurements each]) using dedicated software. The influence of age, body mass index (BMI), and sex on PSL was assessed using the Pearson correlation and repeated measurements. Inter-reader agreement was assessed using the intraclass correlation coefficient (ICC) and Bland Altman (BA) plots. Results: CT images of 15 (6%) patients could not be analyzed. A total of 2750 measurements were performed in the remaining 250 patients (143 male [57%], mean age 45 years [range, 18-91]), and 2237 (81%) values were obtained in the head 951/1250 (76%), body 609/750 (81%), and tail 677/750 (90%). The mean ± standard deviation PSL was 6.53 ± 1.37. The mean PSL was significantly higher in male than in female (6.89 ± 1.30 vs. 6.06 ± 1.31, respectively, p < 0.001). PSL gradually increased with age (r = 0.32, p < 0.001) and BMI (r = 0.32, p < 0.001). Inter-reader agreement was excellent (ICC 0.82 [95% confidence interval 0.72-0.85], with a BA bias of 0.30 and 95% limits of agreement of -1.29 and 1.89). Conclusion: CT-based PSL quantification is feasible with a high success rate and inter-reader agreement in subjects free from pancreatic disease. Significant variations were observed according to sex, age, and BMI. This study provides a reference for future studies.

Purpose : The purpose of the present study is to develop a clinical pathway applied with activity-based management methodology for efficient clinical management to cope with rapid changing medical environments. Method : After making a preliminary pathway based on which a conceptual frame of reference was established to develop a clinical pathway, the final one was confirmed by verifying experts validity and clinical validity. The ultimate activity-based clinical pathway was restructured after clarifying, schematizing and analyzing the whole activities of clinical pathway in accordance with the conducting process of activity-based management. Result : A clinical pathway for total hip replacement was developed, in which the vertical axis consisted of assessment, examination, consultation, medication, treatment, diet, activity, and education, and the horizontal axis was composed of six days of hospitalization. Then, on the basis of the development, the clinical pathway including the improved contents and information was restructured after making the reform measure by analyzing each of activities in the pathway. And the list of contents related to the clinical management activity was made, which was described its main contents and the pre-activities that ought to be completed before conducting each of activities in the pathway. Conclusion : The clinical pathway applied with activity-based management may be used as a standard guidance for providing continuous and consistent patient care. It will provide the information for nursing activities to nurses and the management information about hospital and nursing activities to the hospital administrators. It will also be used as a tool for communication between medical staff. Besides, it will contribute to creating profits for the hospital by shortening the length of stay in patients.

Background: Concurrent chemoradiation with three weekly high dose cisplatin is the non-surgical standard of care for the treatment of locally advanced head and neck cancers. Although this treatment regime is efficacious, it has high acute toxicity, which leads not only to increased treatment cost, but also to increased overall treatment time. Hence, the current study was undertaken to evaluate the acute toxicity and tumor response in head and neck cancer patients treated with concurrent chemoradiation using $40mg/m^2$ weekly cisplatin, which has been our institutional practice. Materials and Methods: This single institution retrospective study included data for 287 head and neck cancer patients treated with concurrent chemoradiation from 2012 to 2014. Results: The mean age of the patients was 48.8 years. The most common site of involvement was oral cavity. Most of the study patients presented with advanced stage disease. The mean overall treatment time was 56.9 days. Some 67.2% had overall complete response to treatment as documented till 90 days from the start of treatment. According to the Radiation Therapy Oncology Group (RTOG) acute radiation morbidity scoring criteria, mucositis was seen in 95.1% of the patients. Dermatitis and emesis were observed in 81.9% and 98.6%, respectively. Regarding haematological toxicity, 48.8% and 29.6% suffered from anaemia and leukopenia, respectively, during treatment. Acute kidney injury was assessed using the Common Terminology Criteria for Adverse Events (CTCAE), and was found in 18.8% of the patients. Conclusions: Concurrent chemoradiotherapy with weekly cisplatin is an effective treatment regime for head and neck cancers with reasonable toxicity which can be used in developing countries, where cost of treatment is so important.

Objectives Antimicrobial chemicals are used in a variety of household and personal care products. Exposure to antimicrobial household products has been hypothesized to lead to allergic diseases in children. Methods We investigated antimicrobial household product exposure and allergic symptoms in Korean children. An antimicrobial exposure (AE) score was derived. To examine the symptoms of allergic diseases (current wheeze, current rhinitis, and current eczema) in the past 12 months, we used a questionnaire based on the core module of the International Study of Asthma and Allergies in Children. Complete data for the analysis were available for 25,805 of the 35,590 (72.5%) children. Results The prevalence of current allergic diseases was as follows: wheeze, 5.6%; allergic rhinitis, 32.6%; and eczema, 17.7%. The mean (standard deviation) AE score was 14.3 (9.3) (range: 0-40). Compared with subjects with a low AE score (reference), subjects with a high AE score (fourth quartile) were more likely to have symptoms of wheezing and allergic rhinitis (adjusted odds ratio [aOR] for wheezing 1.24, 95% confidence interval [CI], 1.05-1.45, p for trend=0.24; aOR for allergic rhinitis 1.30, 95% CI, 1.20-1.40, p <0.01). Conclusions These findings suggest that frequent use of antimicrobial household products was associated with current wheeze and current allergic rhinitis.
The purpose of this study was to get some basic data for health care for working women, especially or hospital nurses. The number of subjects was 796 nurses from one general hospital and four private educational hospitals. The data were collected from February to April, 1988 using the questionnaire "Symptom Table on Fatigue Perception" designed by the Research Committee of Industrial Fatigue in Hygienic Association of Japan Industry. The collected data were analyzed using means and standard deviations for the subjective symptoms of fatigue and each item as an independent variable was analyzed by T-test and ANOVA test. The results are as follows 1) The mean score for degree of fatigue was 1.89 and the degree of fatigue for physical symptoms had highest score of 2.04, the next was psychological symptoms at 1.89, and neuro -sensory symptoms were the lowest at 1.74. Among the fatigue symptoms, the item scored most frequently was "Legs feel heavy" with a mean score of 2.40 and the least frequent item was "My hand and foot trembled" with a mean score of 1.40. 2) With the respect to the general characteristics of subjects, there were statistically significant difference according to age (F=17.039, p=.000), state of marriage(t=5.381, p=.000) presence of children(t=5.134, p=.000), clinical experience (F=16.663, p= .000), present position(F=18.204, p=.000), working place(F=12.598, p=.000), duty time(F=9.068, p=.000), monthly wages(F=7.361, p=.000). satisfaction about the pay and treatment at work(t=-5.511, p=.000), relation the doctors(t=-4.593, p=.000) the doctors(t=-4.593, p=.000)
Purpose: The purpose of this study was to explore EMT-paramedic students' experience of simulation education and analyze the confidence before and after education, learning attitude and course evaluation. Method: Research survey was conducted on 38 EMT-paramedic students during November, 2011 and EMT-paramedic students' experience of simulation education was analyzed after applying head, spinal, and chest injury scenario. The confidence before and after education, learning attitude and course evaluation in gender were analyzed by Mann-Whitny U test and the difference of confidence before and after education was analyzed by Wilcoxon signed rank test and learning attitude & course evaluation were analyzed by evaluating frequency, percentage, mean, standard deviation by using SPSS WIN 17.0 program. Results: 1. Students experienced various advantages such as increasing interest and self-reflection on learning, critical thinking ability, and EMT-paramedic-role experience and recognition of importance of teamwork. Students also pointed out disadvantages such as gap between real situation and simulation, limit of time and equipments, and burden of demonstration. 2. The confidence between before and after education, learning attitude and course evaluation in gender were not significant different statistically. 3. Confidence mean score elevated from 5.53(before education) to 5.87(after education), but the difference in their confidence did not show significant difference statistically. 4. Total mean score in learning attitude after simulation education was 3.70 out of 5.00, which is considerably very high. 5. Total mean score in course evaluation was 3.89 with score of 3.83 in evaluation in learning environment and 3.99 in evaluation of debriefing. Conclusion: The finding of this study demonstrate that the simulation education can provide a safe and repetitive practice environment, improve problem-solving ability and critical thinking, and increase the confidence in prehospital emergency care; therefore, simulation may be the new effective EMT-paramedic education strategy.

Although Korea joined OECD in 1996, there has still seen much unbalance in medical care and welfare standard between urban and rural area. The unbalance of medical demand between urban and rural area deepened low utilization of rural hospitals. So it caused many hospital's failure and conversion in rural area. Many rural hospitals are in difficulty managing business because of low medical demand along with the shortage of medical manpower, medical equipment and facilities. The objectives of this study were to reveal the cause of low utilization of hospitals in rural area, and to increase utilization of those hospitals. In this study the improvement methods of rural hospital's utilization were presented by examining were placed in difficult management condition, in respect of hospital's management conditions, manpower input, patient medical treatment record, financial record, and actual output. The causes of rural hospital's low utilization were as follows; 1) changes in number and structure of population 2) rural people's preference for large hospitals and hospitals which located in urban area 3) rural hospitals lacking in hospital management skill. Consequently rural hospital's operation condition got more and more deteriorated. To raise rural hospital's utilization, method for social policy, method for health policy, and intrinsic method of hospitals were presented in turn. For rural residents to utilize medical service conveniently, it is necessary for rural hospitals operated normally. So government must insist that rural hospitals solve the problems which come out from their internal management problems. And also these rural hospitals should be supported and nurtured by the government until their management is operated normally.

Home health care with compact wearable units sounds to be a convenient solution for the elderly people living independently. This paper presents a method to detect fall from the other activities of daily living and also to classify those activities. This kind of ambulatory monitoring enables them to get an emergency help in the case of the fatal fall event and can provide their general health status by observing the activities being performed in daily life. A tri-axial accelerometer sensor is used to get the acceleration anomalies associated with the user's movements. The three axis acceleration data are transferred to the base station sensor node via an IEEE 802.15.4 compliant zigbee module. The base station sensor node sends the data to base station PC for an offline processing. This work shows the feature set preparation using the principal component analysis (PCA) for the designing of neural network. The work includes the most common activities of daily living (ADL) like Rest, Walk and Run along with the detection of fall events from ADL. The angle from the vertical is found to be the most significant feature parameter for classification of fall while mean, standard deviation and FFT coefficients were used as the feature parameter for classifying the other activities under consideration. The accuracy for detection of fall events is 86%. The overall accuracy for ADL and fall is 94%.
