Lung cancer is one of the most common types of malignancy in western nations with serious health problem, and it has become the leading cause of cancer death of males, second only to stomach cancer, in Korea. A review of the histopathology of 1363 cases (1231 patients) of lung carcinoma, diagnosed at the Keimyung University Medical center from 1987 to 1996, was performed to reclassify the type of carcinomas and to investigate the change in the distribution of histologic types of lung carcinoma according to age, sex and year. Among the 1363 cases, 132 patients underwent a surgical operation after biopsy. The diagnosis of each case was proven by histopathologic analysis of surgical specimens (13.2%) and biopsy materials (86.8%). The histologic types in our study were basically based on modified WHO classification (1982) and on new WHO classification (1999). The classification of small cell carcinoma was based on International Association for the Small Cell Lung Cancer (IASLC, 1988). Of the 1231 patients with lung carcinoma, 1012 were male and 219 were female (male to female ratio was 3.6:1). According to the analysis of age distribution, the most prevalent age group was 60~69 years in both sex as (n=516, 42.0%). Changing trends in sex distribution of lung carcinoma patients showed that the proportion of men had decreased throughout the years, whereas the proportion of women had significantly increased. Histologically, squamous cell carcinoma was the most common (n=624, 50.7%), followed by small cell carcinoma (21.1%), adenocarcinoma (18.1%), large cell undifferentiated carcinoma (2.1%), adenosquamous carcinoma (0.4%), and large cell neuroendocrine carcinoma (0.4%), in order of frequency. In men, squamous cell carcinoma was the most frequent type (55.1%). In women, adenocarcinoma was the most frequent type (39.7%). In both sexes, adenocarcinoma was the most common type in patients under the age of 40 (n=12, 41.4%), while squamous cell carcinoma proved the most frequent type in patients over the age of 40 (n=617, 51.3%). Changing trends of histologic types of lung cancer showed that the incidences of squamous cell carcinoma had significantly decreased throughout the years, whereas those of adenocarcinoma and small cell carcinoma had increased. In conclusion, the results showing increases in the percentage of female patients and in the number of cases of adenocarcinoma were noteworthy, and well correlated with other related reports.

OBJECTIVES: This study examined the relationship between the personality traits and job performance of Centers for Children's Foodservice Management (CCFSM) staff on emotional exhaustion and job satisfaction. In addition, the characteristics of the center organization were examined to provide practical guidelines for the operation of the center. The aim was to determine management implications with an important meaning in human resource management to enhance the efficiency of the operation of Centers for Children's Foodservice Management (CCFSM). METHODS: Out of 207 centers, there were 1,057 employees at 173 centers who agreed to participate in the study, the questionnaire was mailed on February 17, 2017 and collected by mail on March 31, 2017. Finally, 81 centers (46.82%) participated in the survey and 493 questionnaires were used. RESULTS: Neuroticism among the five personality factors had a positive (+) influence on ‘cynicism’ and ‘exhaustion’ among the three subordinate factors of emotional exhaustion, negative (−) effects on the ‘job’ among the six subscales of job satisfaction. In addition, openness showed a negative (−) effect on ‘loss of professional confidence’ of emotional exhaustion and positive (+) relationship with the ‘job’ of job satisfaction. Agreeableness appeared to have a negative (−) effect on all factors of emotional exhaustion and a positive (+) influence on all factors of job satisfaction. As a result of analyzing the effects of job performance on emotional exhaustion and job satisfaction, the planning and operations management team showed a positive (+) influence on all factors of emotional exhaustion and negative (−) influence on all factors of job satisfaction. On the other hand, the nutrition management team showed a negative (−) influence on all emotional exhaustion factors and a positive (+) influence on the factors of job satisfaction. The hygiene management team showed a positive (+) relationship with ‘Emotional exhaustion’ among the subordinate factors of emotional exhaustion and a negative (−) influence on the ‘Educational opportunity’ of job satisfaction. CONCLUSIONS: The personality type and job performance of Centers for Children's foodservice management (ccfsm) staff significantly affected the emotional exhaustion and job satisfaction.

OBJECTIVES: This study aimed to assess the improvement of teachers' sanitation performance and food distribution environment at Centers for children's food service management after a sanitation education program. METHODS: The subjects were 119 teachers working at child care centers registered in the Daejeon Center for Children's Foodservice Management in Dongu and Jung-gu, Daejeon. The sanitation education was provided three times from March to August in 2014, and the survey questionnaires were distributed before and after the education. The sanitation status of food service environment of the centers was examined by ATP(adenosine-5'- triphosphate) bioluminescence. RESULTS: After the sanitation education, the teachers showed higher levels of sanitation knowledge. Also, sanitation performance and recognition level of the importance of it significantly improved after the education program. The mean variation scores of importance and performance after the education were 0.14 and 0.23. According to the Importance-Performance Analysis (IPA) results of 26 sanitation attributes about the food service environment, the selection attributes with relatively low performance and importance were mostly distributed in the children's and distributer's personal hygiene management area. However, all attributes except using a personal water bottle and cup were moved to high performance and importance level. Also, the ATP examination results showed that the sanitation status of the food service environment was improved after the education program. CONCLUSIONS: The sanitation education program was effective in improving the recognition of the importance of sanitation and its performance with regard to food service management.

Purpose: : This study aimed to compare peripheral pulse oxygen saturation (SpO2) values, measured at different monitoring sites, and arterial oxygen saturation (SaO2) of neurocritical patients. Methods: : The study included 110 patients admitted to the neurosurgical intensive care unit of a university hospital. The patients’ SpO2 values were measured in their index fingers, both second toes, both earlobes, and foreheads, using the patient monitoring system. These values were compared with the standard value of SaO2 measured using a blood gas analyzer. Data were analyzed using descriptive values, Pearson’s correlation coefficients, Lin’s concordance correlation coefficients (CCC), and Bland-Altman plots.Result : Regardless of the measuring site, SpO2 was correlated with the paired measurements of SaO2 (r=.40~.60, p＜.001, CCC range=.40~.58). No significant bias in paired measurements of SpO2 and SaO2 was observed at all sites (-0.06~0.19%, p＞.05). SpO2 values at the left finger and right earlobe had the narrowest range, with a 95% limits of agreement (LOA) (left finger -3.04~2.93% and right earlobe -3.18~2.79%). SpO2 at the index finger, on the side without an arterial catheter, had a narrower range of 95% LOA than that of the opposing finger (-3.00~2.97% vs. -3.73~3.26%). Conclusion : SpO2 at the finger without an arterial catheter had the highest level of precision. This study suggests using the index finger, on the side without an arterial catheter, for pulse oximetry in neurocritical patients.

BACKGROUND/OBJECTIVES: Recent studies have reported chocolate consumption has beneficial effects on blood pressure, obesity, and dyslipidemia, which are components of metabolic syndrome (MetS). However, evidence regarding these relationships in Asia is limited. The aim of this study was to investigate relations between chocolate consumption and MetS in Korea. SUBJECTS/METHODS: Study subjects were 6,982 adults aged 19-64 years free of major chronic diseases that participated in the 2014–2016 Korea National Health and Nutrition Examination Survey. Information on chocolate consumption was obtained using food frequency questionnaires. For primary analysis, subjects were divided into two groups:non-consumer (n = 3,741, 53.6%); consumer (n = 3,241, 46.4%). In order to investigate doseresponse effects on MetS, chocolate consumers were divided into quartiles based on amounts consumed: Q1 (n = 789, 24.3%); Q2 (n = 837, 25.8%); Q3 (n = 863, 26.6%); Q4 (n = 752, 23.2%) in second analysis. RESULTS: Chocolate consumers; 1) were more physically active(P < 0.0001); 2) less likely to smoke(P < 0.0001); 3) paid more attention to food nutrition labels (P < 0.0001), and 4) had healthier dietary patterns, that is, they consumed vegetables, fruits, and dairy products more frequently(P < 0.0001) than non-consumers. Furthermore, chocolate consumers had a 30% lower risk of MetS (odds ratio, 0.70; 95% confidence interval, 0.58–0.86; P = 0.0005).However, dose-response effects between chocolate intake and MetS was not found by secondary analysis after excluding non-consumers. CONCLUSIONS In conclusion, chocolate consumers had healthier lifestyles and dietary patterns and a lower prevalence of MetS than non-consumers, as determined by our primary analysis. Although dose-response effects were not found to be significant among chocolate consumers during secondary analysis, the patterns were partially similar. This cross-sectional finding shows chocolate consumption does not increase the risk of MetS. The prospective studies and intervention trials in Korea are needed to confirm this cross-sectional finding.

Nutrition education is essential for the health of people with disabilities. This paper presents nutrition education topics and operational directions for people with disabilities living in social welfare facilities for people with disabilities. This study was conducted through one-on-one, in-depth interviews with 11 operators and workers at social welfare facilities where people with disabilities reside. They were asked about the current status of nutrition education at the social welfare facility for people with disabilities where the interviewee works, major diseases of residents, topics of nutrition education needed, and preferred education methods to determine the type of nutrition education for people with disabilities needed in the field. As a topic of nutrition education, dietary education for obesity prevention and management was most requested, and education on basic nutritional ingredients was also desired. It was mentioned that the educational level would be appropriate for children aged 6∼9, and using materials that would attract interest was recommended. Activity-based face-to-face education was preferred for the operation of the program, and it was mentioned that education would be possible in a short period. In addition, it was mentioned that nutrition education is necessary for people with disabilities and workers at social welfare facilities for people with disabilities. Confirming the topic and operation direction of the nutrition education program required by social welfare facilities for people with disabilities will make it possible to contribute to providing nutrition education tailored to social welfare facilities for people with disabilities in Korea.

BACKGROUND: Although pulmonary artery catheters are useful to monitor hydration, these devices may be associated with severe morbidity and are not routinely used in kidney transplantation. A central venous pressure (CVP) catheter is preferred rather than a pulmonary artery catheter. Noninvasive continuous blood pressure monitors may substitute for intraarterial catheters, thereby preserving the radial artery in kidney transplantation patients should it be needed later to create an arteriovenous fistula. If there is a relationship between central venous and radial arterial blood for acid-base (pH, BE, HCO3(-)), we can use the blood sample from a CVP catheter instead of arterial blood from aradial artery catheter for testing acid-base and it can help patients. METHODS: A central venous catheter and radial artery catheter was inserted in 67 patients while undergoing kidney transplantation. To assess arteriovenous differences in acid-base status at operation start, before reperfusion of the transplanted kidney, after reperfusion, we measured the pH, BE and HCO3(-) simultaneously from the arterial and central venous circulation. RESULTS: Aacid-base using arterial and central venous samples at operation start, before reperfusion and after reperfusionb was evaluated. We found the relationship as follows: pH between arterial (pHa) and central venous blood (pHcv) in each: linear regression equation; pHcv = 0.668 + (0.906 X pHa), pHcv = 0.225 + (0.965 X pHa), pHcv = 0.646 + (0.908 X pHa), determination coefficient; 0.908, 0.926, 0.888, P values < 0.001 in each period. Base excess (BE) between BEa and BEcv in each period: linear regression equation; BEcv = 0.483 + (0.952 X BEa), BEcv = 0.032 + (0.939 X BEa), BEcv = 0.008 + (0.954 X BEa), determination coefficient; 0.844, 0.954, 0.962 P values < 0.001 in each period. HCO3(-) concentration between HCO3(-)a and HCO3(-)cv in each period: linear regression equation; HCO3(-)cv = 2.434 + (0.937 X HCO3(-)a), HCO3(-)cv = 2.093 + (0.942 X HCO3(-)a), HCO3(-)cv = 1.755 + (0.954 X HCO3 a), determination coefficient; 0.950, 0.925, 0.932 P values < 0.001 in each period. CONCLUSIONS: The acid base status of arterial blood is similar to that of central venous blood. Central venous blood gas values (pH, BE, HCO3(-)) may be an acceptable alternative to arterial blood gas values in kidney transplantation patients.
