The aim of this study was to examine fluid excretions and changes in deceased bodies depending on type, location of, and causes of death for hygienic management of funeral homes. Based on the 858 cadavers studied, the average age at the time of death is 68.6 years, 83.0% had illness as the cause of death, and 79.5% passed away in a medical facility. Fluid excretion was observed in 46.2% of the cadavers. In manner of death, 78.8% of deaths -highest percentage- was due to an accident and 10.8% of deaths - lowest percentage- was due to age. Fluid excretion was observed in 46.3% of cadavers from medical facilities, 38.6% of cadavers from homes and 77.4% of cadavers from miscellaneous locations. There were various number of cadavers with recorded immediate, secondary and underlying cause of death; however, the fluid excretion rate was similar. In analyzing the immediate, secondary and underlying cause of death, respiratory and heart disease were the most common causes of death in categories of body organ and system. In terms of fluid excretion, liver disease followed by digestive and circulatory diseases were most common in immediate cause of death. Accidents and miscellaneous circumstances were most common amongst secondary and underlying causes of death for cadavers with fluid excretion. Based on the recorded illnesses of the cadavers, cardiopulmonary failure was most common as evident in 96 cadavers followed by pneumonia and sepsis. Cholangiocarcinoma (73.3%) had the highest rate of fluid excretion followed by pancreatic cancer, severe brain injury and liver cancer amongst categories of illnesses with more than 15 cadavers.

This study investigated the characteristics and factors affecting inpatient infants, children, and adolescents who experienced falling, using NHDIS data from 2008 through 2017, The study analyzed data of 116 patients who were under 18 and who experienced injuries (KSCD, S00-S99) by falling (KSCD, W00-W19). Frequency analysis, cross-tabulations, and multiple regression analysis were conducted, using SPSS 23. There were more boys than girls, and most of the falls occurred at the ages of over one to under six years old. Most of the children had respiratory diseases, and most had open wounds or bruises due to falling. Also, most of the falls were related to the bed. In the factor analysis, age (β=.318), the main diagnosis (β=.231), and injury (β=.169) except gender affected falling. This suggests that it is necessary to conduct fall prevention education for children, considering the developmental stage characteristics and age group. It is necessary to screen the risk group such as children with a disease with relatively less restriction of activities or with a hyperactive disorder, and to develop a related manual. Hopefully, the results will be used as the basic data for fall prevention education and creating a fall prevention manual according to the characteristics of children's developmental stage for patients who need hospitalization, their caregivers, and the relevant medical team.

A comparison of analytical approaches for Levoglucosan ($C_6H_{10}O_5$, commonly formed from the pyrolysis of carbohydrates such as cellulose) and used for a molecular marker in biomass burning is made between the four different analytical systems. 1) Spectrothermography technique as the evaluation of thermograms of carbon using Elemental Carbon & Organic Carbon Analyzer, 2) mass spectrometry technique using Gas Chromatography/mass spectrometer (GC/MS), 3) Aerosol Mass Spectrometer (AMS) for the identification of the particle size distribution and chemical composition, and 4) two dimensional Gas Chromatography with Time of Flight mass spectrometry (GC${\times}$GC-TOFMS) for defining the signature of Levoglucosan in terms of chemical analytical process. First, a Spectrothermography, which is defined as the graphical representation of the carbon, can be measured as a function of temperature during the thermal separation process and spectrothermographic analysis. GC/MS can detect mass fragment ions of Levoglucosan characterized by its base peak at m/z 60, 73 in mass fragment-grams by methylation and m/z 217, 204 by trimethylsilylderivatives (TMS-derivatives). AMS can be used to analyze the base peak at m/z 60.021, 73.029 in mass fragment-grams with a multiple-peak Gaussian curve fit algorithm. In the analysis of TMS derivatives by GC${\times}$GC-TOFMS, it can detect m/z 73 as the base ion for the identification of Levoglucosan. It can also observe m/z 217 and 204 with existence of m/z 333. Although the ratios of m/z 217 and m/z 204 to the base ion (m/z 73) in the mass spectrum of GC${\times}$GC-TOFMS lower than those of GC/MS, Levoglucosan can be separated and characterized from D (-) +Ribose in the mixture of sugar compounds. At last, the environmental significance of Levoglucosan will be discussed with respect to the health effect to offer important opportunities for clinical and potential epidemiological research for reducing incidence of cardiovascular and respiratory diseases.

Apios americana Medik (hereinafter Apios) has been reported to treat diseases, including cancer, hypertension, obesity, and diabetes. The therapeutic effect of Apios is likely to be associated with its anti-inflammatory activity. This study was conducted to evaluate the protective effects of Apios in animal models of acute lung injury induced by lipopolysaccharide (LPS) or pandemic H1N1 2009 influenza A virus (H1N1). Mice were exposed to LPS or H1N1 for 2-4 days to induce acute lung injury. The treatment groups were administered Apios extracts via oral injection for 8 weeks before LPS treatment or H1N1 infection. To investigate the effects of Apios, we assessed the mice for in vivo effects of Apios on immune cell infiltration and the level of pro-inflammatory cytokines in the bronchoalveolar lavage (BAL) fluid, and histopathological changes in the lung. After induction of acute lung injury, the numbers of neutrophils and total cells were lower in the Apios-treated groups than in the non-Apios-treated LPS and H1N1 groups. The Apios groups tended to have lower levels of tumor necrosis factor-a and interleukin-6 in BAL fluid. In addition, the histopathological changes in the lungs were markedly reduced in the Apios-treated groups. These data suggest that Apios treatment reduces LPS- and H1N1-induced lung inflammation. These protective effects of Apios suggest that it may have therapeutic potential in acute lung injury.

In this study, the shoot clumps extract of tissue-cultured Raoulia australis using the bioreactor culture system was tested for use a natural cosmetic ingredient. Tissue-cultured R. australis shoot clumps extract was tested anti-oxidant and anti-inflammatory activity for a cosmetic application. R. australis is a wild herbaceous plant of the asteraceae growing in New Zealand and Australia. Previous studies have reported anti-viral activity of the inhibitory effects for the growth of viruses induced meningitis, bronchitis and respiratory diseases but other biological effects are unknown. The shoot clumps extract of tissue-cultured R. australis showed higher anti-oxidant effect and anti-inflammatory effect than the natural R. australis extract. In DPPH, NBT and ABTS assay, the shoot clumps extract of tissue-cultured R. australis enhanced radical scavenging activity (up to 10~25% at $50{\mu}L/mL$) more than the natural R. australis extract. Also, the shoot clumps extract of tissue-cultured R. australis inhibited expression of iNOS and COX-2 protein in LPS-stimulated Raw 264.7 macrophages more than the natural R. australis extract. From this study, the shoot clumps extract of tissue-cultured R. australis displayed strong possibility as a new natural cosmetic ingredient for skin-care products.

The occupational health nursing guideline for primary care was developed by the Korean Academic Society of occupational health nursing and the organization for occupational health nurses (currently known as the Korean Association of Occupational Health Nurses) in 1993. Since then, there have been many changes in the health care environment and job performance of occupational health nurses. Appropriate revisions are necessary of the guidelinea based on this background. The purpose of this study was to describe the use of the occupational health nursing guideline for primary care and to analyze the characteristics of primary care activities by occupational health nurses. The questionnaire was mailed to 150 occupational health nurses(OHNs) with the response rate of 64%. The results can be summarized as follows; 1. 65.6% of OHNs have been using the guideline for primary care and 75.9% of them agreed that the guideline was be helpful for their job. 2. Common symptom care, emergency care and chronic illness care were more frequently implemented than occupational disease care by OHNs. In manufacturing industries, emergency care was more frequently implemented than chronic illness care in contrast to the service industries. 3. Most frequent common symptoms treated by OHNs were indigestion, diarrhea, abdominal pain, headache, and coughing. In the case of chronic illness, OHNs more frequently treated diseases of the gastro-intestinal system, skin and sensory organs, and the respiratory system. Emergency care for bruises, burn, and abrasions was more frequently provided. VDT syndrome was the most common occupational disease cared by OHNs in manufacturing and service industries. 4. OHNs prescribed the medicine for external application more frequently than internal medicine. Remedy for colds, analgesics, vitamins, and digestives were more frequently used. From these results, we suggest that the guideline should be revised to emphasize the activities consisting problem finding such as health assessment, physical examinations, monitoring and screening, and to renew the drug list in the range of over- the counter medication (OTC). In the future, the guideline will include the strategies for the role as the case manager.

This study was carried out to identify basic data for more efficient operation of comprehensive health check-up centers in the national health care system. The researcher reviewed and analyzed the main symptoms of the subjects according to sex, age, occupation and positive rate in the screening tests of a comprehensive health check-up, performed at one comprehensive health check-up center in located in a hospital. The subjects were 512 persons who had a check-up at the comprehensive health check-up, center in K university hospital in Seoul from October 2, 1996 to March 30, 1997. A questionaire developed by the researcher to obtain subject's general characteristics, main symptoms, medical examination, diagnosed disease was used as the tool for the study. The researcher analyzed the data with SPSS PC/sup +/ program. : the distribution of the subject's general characteristics and main symptoms was described with percentages and the difference between main symptoms and screening tests analyzed with X²-test, t-test, ANOVA. The result of this study are as follows : 1. For the distribution of diagnosis in males. liver disease was most frequent and hypertension was second : in females, hypertention and liver disease were not common in that order. 2. The most common complaints were indigestion in the digestive system, sputum in the respiratory system, irregular heart beat in the cardiovascular system, frequent urine in the urinary system vertigo in the hematologic system. 3. The main symptoms according to sex were for females, a statistically siguificant higher rate of complaints in the digestive system, cardiovascular system, urinary system, hematologic system, musculoskeletal, mental & nervous system as compared to males. 4. The main symptoms according to age were that in the the second decade there wara higher rate of complaints in the digestive system, and cardiovascular system than in the older age groups : and in the fifth decade more in the musculoskeletal system. 5. The main symptoms according to occupation were that formers and fishers had a higher rate of complaints in the mental and nervous system as compared to other occupation groups : and office workers, in gynecology. 6. The main symptoms according to diagnosis, were symptoms of the digestive system, frequent in liver disease : symptoms of the cardiovascular system in allergic disease. 7. The screening tests which showed the highest rates were UGI /FGS, PFT : In males a higher rate of abnormality was seen in abdominal ultrasono- graphy and in, females, in mammography. 8. In screening tests according to sex, males showed a higher positive rate for chest X-rays, and LFT, and females, in mammography, pap smear, CBC. 9. In screening tests according to age, higher positive rates of obesity, high blood pressure, chest X-ray, mammography, pap smear, FBS, CBC, urine test were seen in the fifth decade : PFT and abdominal ultrasonography in the third decade. The subjects who wanted comprehensive health check-up were not asymptomatic but had an illness with several symptoms. It is found that the most frequent diagnosed diseases were hypertention and liver disease. So proper observations must be done for them. Comprehensive health check-ups should be changed to a comprehensive examination including treatment beyond examination for those subjects with positive results.

Objectives : The object of this study was to obtain acute toxicity information (single oral dose toxicity) of Armeniacae Semen (AS), a medicinal herb used for treating constipation and various respiratory diseases, in rats. Methods : In order to observe the $LD_{50}$ (50% lethal dose), approximate lethal dosage (ALD) and target organs, AS aqueous extracts were orally administered once to female and male Sprague Dawley rats at dose levels of 2,000, 1,000, 500 and 0 (control) mg/kg (body weight). The mortality, changes in the body weight, clinical signs and gross observation were monitored for 14 days after single oral treatment of AS extracts, and the organ weights and histopathological findings of principle organs were observed after sacrifice. Results : After single oral treatment of AS 2,000 and 1,000 mg/kg, all (5/5; 100%) female and male rats died within 30 minutes after treatment, while no mortalities were observed in the female and male rats treated with 500 mg/kg of AS extract. Therefore, $LD_{50}$ in female and male rats was calculated as 741.95 mg/kg. Seizure, loss of locomotion, salivation, increases of respiration and heart-beat were observed after AS extract treatment, which were observed in all rats including the lowest dosage group, 500 mg/kg in the present study. In addition, lung congestion was visible in all mortal rats with AS 2,000 and 1,000 mg/kg, respectively. Conclusions : The results obtained in this study suggest that AS extract ranges in Class III, because the $LD_{50}$ and ALD in both female and male rats were calculated as 741.95 mg/kg and 500~1,000 mg/kg, respectively. However, AS extract should be carefully treated at clinical applications, because salivation, increase of respiration and heart-beat were also observed in the lowest dosage group, 500 mg/kg in the present study.

Purpose: This study investigated an outbreak of mumps affecting students in a high school (S high school) in Seoul, with an evaluation of the diagnostic utility of the mumps polymerase chain reaction (PCR) assay. Methods: S high school students that presented to health care providers with mumps symptoms between April 2013 and July 2013 were surveyed for the monthly distribution of symptom onset and their grade level. Mumps PCR assays were performed using buccal swabs from some of these students. Results: During the survey period, 77 students presented with suspected cases of mumps. The monthly distribution of symptom onset was as follows: one in April, 17 in May, 54 in June, and five in July. With regard to grade level, 26 students were in their first year, 28 were in their second year, and 23 were in their third year. Of the 18 students tested with PCR assays, five had positive results. Samples were collected within 3 days of symptom onset in 15 of the 18 students, and positive PCR results were obtained in five of these 15 students. The PCR results of the remaining three students from whom samples were collected more than 3 days after the onset of symptoms were negative (P=0.24). Conclusions: We evaluated the epidemiological aspects of an outbreak of mumps in a high school. Mumps PCR might be epidemiologically useful if performed within 3 days of the onset of symptoms in suspected cases.
