Purpose:
The purposes of this study were to understand the health interest of consumers in the United States and Japan and thus understand the motivation of food choices, in order to provide basic data on the country's strategy based on healthy and correct food choices in the future.
Methods:
A customer survey was conducted in 2019 from October 18 to 31, and it targeted 115 American and 120 Japanese local consumers between the ages of 20- to 64-years-old. Eight questions were formed using General Health Interest. Based on food choice motivation, 27 questions were reconstructed and asked about demographic information. All data were analyzed by SPSS Statistics (ver. 25).
Results:
Health consciousness was categorized into 2 types: nutrition-seeking type and preference-seeking type. Based on these 2 factors, customers were grouped into 3 clusters:healthy dietary life-seeking group, nutrition balance-seeking group and health indifference group. Food choice motivation was categorized into 4 types: health, efficiency, value, and mood. All 3 groups showed a high tendency for efficiency in common. The results show that consumers want higher satisfaction with their time and money invested in food consumption. It is believed that the focus and investment of market segmentation strategy should be focused on product development, especially for American and Japanese consumers who are interested in health.
Conclusion
The results of this study reflect consumer needs that can assist in the selection of healthy and correct foods in the future.

BACKGROUND: Recently, patients' demands for emergency medicine are increasing, and most of prehospital medical care, including basic life support, cardiopulmonary resuscitation and triage, are provided by paramedics or emergency medical technicians. Evaluation of the adequacy of prehospital management and triage has become important for improving the quality and the effectiveness of the emergency medical system. METHODS: The 202 patients who were transferred by ambulance with paramedics, nurses, or emergency medical technicians to the Emergency Department in Gil Medical Center from July 1, 1999, to September 31, 1999, were enrolled. This study was conducted prospectively by using the emergency physician's log and newly devised protocols recorded by paramedics or nurses. RESULTS: 1) Male to female ratio was 1:0.8, and the peak age of the patients were the 4th(18.8%) and 6th decade(15.3%). 2) Of the 202 patients, 84 patients were transferred for trauma and 118 for medical problems. The mean transfer time was 6+/-1.73 minutes. 3) The validities of prehospital triage and decisions using the trauma severity measure and the disease severity measure, were 33.3% in trauma patients and 57.6% in medical patients. 4) The results for the adequacy rate in prehospital management analyzed by using the rate of necessity of treatment, performance of treatment, and adequate treatment were as follows: oxygen supply, 38.1/41.6/93.8; wound dressing, 19.3/71.8/92.9; immobilization of the cervical spine, 15.8/56.3/92.9; application of a spinal board, 12.9/42.3/72.7; application of a splint, 9.9/50.0/60.0; manual maintenance of an airway, 9.9/55.0/63.6; and CPR, 4.5/66.7/0.5) Kind of ALS(Advanced Life Support) were not conducted(peripheral IV, EKG, intubation medical administration, defibrillation, pacing). The rates of necessity of treatment were as follows: peripheral IV, 40.6%; ECG monitoring, 23.3%; endotracheal intubation, 8.9%; medical administration, 8.9%; defibrillation, 3.5%; and pacing, 1.5%. CONCLUSION: The adequacy of prehospital triage and decisions using trauma and disease severity measures was relatively low. To improve the adequacy of BLS(Basic Life Support) and to increase the performance of ALS(Advanced Life Support), we must create challenges to develop new protocols and to supplement new equipment.

PURPOSE: The cytotoxicity by 5-fluorouracil (5-FU) is mediated by inhibition of thymi- dylate synthase (TS), which is a rate-limiting enzyme for DNA synthesis. To test whether the resistance to 5-FU would be associated with cellular TS activity, we analyzed TS gene expression from human gastrointestinal cancer cell lines. MATERIALS AND METHODS: We established the experimental conditions for quantitating TS mRNA expression by competitive RT-PCR using mimic DNA. Based on this method, we compared TS mRNA expression between 5-FU resistant cell line and parent cell line and investigated the expression of TS mRNA following 5-FU administration in 6 human gas- trointestinal cancer cell lines. RESULTS: Competitive RT-PCR using mimic DNA seemed to be more effective than Northern blot analysis for quantitation of TS gene expression. The quantity of TS mRNA and IC50 value of 5-FU in 5-FU resistant H630 was found to be 2.5 and 10 times higher than in parent cell line, respectively. And also, we observed linear relationship between TS mRNA level and IC50 value of 5-FU (r 0.76) in 6 gastrointestinal cancer cell lines. CONCLUSION: These results suggest that overexpression of TS mRNA may play a role in the development of 5-FU resistance in human gastrointestinal malignancies

Objectives:
The purpose was to identify the ingredients that are usually surveyed for assessing real prices and to present the demand for such surveys by nutrition teachers and dietitians for ingredients used by school foodservice.
Methods:
A survey was conducted online from December 2019 to January 2020. The survey questionnaire was distributed to 1,158 nutrition teachers and dietitians from elementary, middle, and high schools nationwide, and 439 (37.9% return rate) of the 1,158 were collected and used for data analysis.
Results:
The ingredients which were investigated for price realities directly by schools were industrial products in 228 schools (51.8%), fruits in 169 schools (38.4%), and specialty crops in 166 schools (37.7%). Moreover, nutrition teachers and dietitians in elementary, middle, and high schools searched in different ways for the real prices of ingredients. In elementary schools, there was a high demand for price information about grains, vegetables or root and tuber crops, special crops, fruits, eggs, fishes, and organic and locally grown ingredients by the School Foodservice Support Centers. Real price information about meats, industrial products, and pickled processed products were sought from the external specialized institutions. In addition, nutrition teachers and dietitians in middle and high schools wanted to obtain prices of all of the ingredients from the Offices of Education or the District Office of Education.
Conclusions
Schools want to efficiently use the time or money spent on research for the real prices of ingredients through reputable organizations or to co-work with other nutrition teachers and dietitians. The results of this study will be useful in understanding the current status of the surveys carried out to determine the real price information for ingredients used by the school foodservice.

BACKGROUND: There is a lack of statistical analysis investigating the relationship between sleep problems and commute time in Korea. We aimed to analyze the association between representative health symptoms, sleep disturbances, and commute time according to working hours in Korea.METHODS: The 4th Korean Working Conditions Survey data were used for analysis, and unpaid family workers and workers who work fewer than three days in a week were excluded. Commute time, working hours, and sleep hours were assessed using self-reported questionnaires. Odds ratios (ORs) with 95% confidence intervals (CIs) for sleep problems were calculated using a multivariate logistic regression model with ≤10 min commute time as the reference group.RESULTS: Among a total of 28,804 workers (men = 14,945, women = 13,859), 2.6% of men and 3.2% of women experienced sleep problems. In both sexes, long commute time (51–60 minutes and >60 minutes) showed an increased OR [men, 2.03 (CI = 1.32–3.13) and 2.05 (CI = 1.33–3.17); women, 1.58 (CI = 1.05–2.39) and 1.63 (CI = 1.06–2.50), respectively]. In stratification analysis of working hours, long commute time (51–60 and > 60 minutes) showed an increased OR in men working >40 hours/week [2.08 (CI = 1.16–3.71) and 1.92 (CI = 1.08–3.41), respectively]. Furthermore, long commute time (41–50, 51–60, and >60 minutes) showed an increased OR in women working >40 hours/week [2.40 (CI = 1.27–4.55), 2.28 (CI = 1.25–4.16), and 2.19 (CI = 1.17–4.16), respectively]. Moreover, commute time >60 minutes showed an increased OR in women working ≤40 hours/week [1.96 (CI = 1.06–3.62)].CONCLUSION: This large cross-sectional study highlights that long commute time is related to sleep problems in both sexes. Shorter commute times and decreased working hours are needed to prevent sleep problems in workers.

PURPOSE: Early diagnosis and management of therapeutic interventions are very important in chest trauma. Conventional chest X-rays (CXR) and computed tomography (CT) are the diagnostic tools that can be quickly implemented for chest trauma patients in the emergency department. In this study, the usefulness of the CT as a diagnostic measurement was examined by analyzing the ability to detect thoracic injuries in trauma patients who had visited the emergency department and undergone CXR and CT. METHODS: This study involved 84 patients who had visited the emergency department due to chest trauma and who had undergone both CXR and CT during their diagnostic process. The patients' characteristics and early vital signs were examined through a retrospective analysis of their medical records, and the CXR and the CT saved in the Picture Archiving Communication System (PACS) were examined by a radiologist and an emergency physician to verify whether or not a lesion was present. RESULTS: Pneumothoraxes, hemothoraxes, pneumomediastina, pulmonary lacerations, rib fractures, vertebral fractures, chest wall contusions, and subcutaneous emphysema were prevalently found in a statistically meaningful way (p<0.05) on the CT. Even though their statistical significance couldn't be verified, other disorders, including aortic injury, were more prevalently found by CT than by CXR. CONCLUSION: CT implemented for chest trauma patients visiting the emergency department allowed disorders that couldn't be found on CXR to be verified, which helped us to could accurately evaluate patients.

Bilateral diaphragmatic paralysis is a rare disease. It is caused by trauma, cardiothoracic surgery, neuromuscular disorders, cervical spondylosis, and infection. A 60 year-old male patient developed bilateral diaphragmatic paralysis after an en-bloc resection of thymic carcinoma which invaded the right upper lobe, pericardium, superior vena cava and innominate vein. Severe respiratory difficulty developed and ventilator weaning was impossible. We performed bilateral diaphragmatic plication. After the operation, satisfactorily ventilator weaning and sleeping in supine position were possible; therefore, we report this case.

Although it is rare, the right atrium can be encroached on by abnormal mediastinal structures, including aortic aneurysms, carcinomas, hepatic cysts and diaphragmatic paralysis. Extrinsic compression of the right atrium causes significant hemodynamic compromise and can lead to fatal outcomes. We describe the case of a 66-year old man with a past history of pulmonary tuberculosis that had undergone right pneumonectomy 40 years previously. He then presented with signs and symptoms of right-sided heart failure. These new signs and symptoms were recognized to be secondary to extrinsic compression of the right atrium, which was due to late-onset postpneumonectomy empyema, and the signs and symptoms were successfully relieved by performing open drainage of the empyema.
