Pyomysitis is a primary acute bacterial infection of large skeletal muscule, usually occuring in the absence of specific cause of infection. Pyomyositis has been reported mainly in tropical countries and was rare in temperate climates. but it has been recognized with increasing frequency. Toxic shock syndrome(TSS) is an acute mutisystemic disease characterized by high fever, hypotension, multisystem dysfunction and erythematous rash followed by skin desquamation 8-12 days after onset. Especially, TSS and pyomyositis are rare conditions in the pediatric population. We experienced one case in a healthy 13-year-girl who developed pyomyositis of the right ileac and gluteal muscles associated with TSS caused by methicillin resistant Staphylococcus aureus. We reports a case of acute pyomyositis with TSS, in which the diagnosis was difficult because of the relative rare incidence in temperate climates and its vague symptoms. To our knowledge, this is the first reported case of pyomyositis with TSS in Korean pediatric population.

Imperforate hymen is, with an incidence of 0.1%, a rare female anomaly, which can appear with symptoms such as lower abdominal pain, primary amenorrhea, dysuria, anuria, caused by retention of menstrual blood after the onset of menstruation. Generally urinary retention is caused by psychological conditions, drug effect, infection or congenital anomaly causing acute urinary obstruction. We experienced a patient with symptoms of acute urinary retention, suggesting acute urinary obstruction. The cause for the retention turned out to be an imperforated hymen, which should therefore be mentioned in the literature as a possible cause in cases suspected of urinary retention.

Background : Iron deficiency anemia(IDA) is a very common condition, and its underlying causes are diverse. Gastrointestinal blood loss, pregnancy, menorrhagia are known as common causes of IDA. However, especially in the IDA case of unknown origin, we must consider the culture specific cause of IDA as a possible cause of IDA. As I found an unusual cause of IDA related to a cultural behavior, I would like to report two cases of IDA occurred by negative therapy in Korea. It is possible to explain these cases by explanatory model. Case 1 : With a chief complaint of dyspnea, a 27-year-old woman visited our clinic. She had multiple treatment histories of negative therapy for her psoriasis. The blood loss during this procedure is the cause of present IDA. Case 2 : A 70-year-old man visited our clinic complaining of anorexia and dizziness. The history of treatment showed that he had an IDA 9 month ago. The IDA developed again because of repeated negative therapy after previous treatment of IDA. He has used the negative therapy intermittently to treat tinea pedis for 5 years. Conclusion : We must consider the negative therapy as a possible cause of IDA in Korea.

The variability of vegetation is strongly related to the variability of hydrometeorological factors such as precipitation, temperature, runoff and so on. Analysis of the variability of vegetation will aid to understand the regional impact of climate change. Thus we analyzed the spatial-temporal variability of NOAA(National Oceanic and Atmospheric Administration)/AVHRR(Advanced Very High Resolution Radiometer) NDVI(Normalized Difference Vegetation Index). In the results from Mann-Kendall test, there is no significant linear trend of annual NDVI from 1982 to 2006 in the most area except the downward trend on the significance level 90% in the Guem-river basin area. In addition, using EOF(Empirical Orthogonal Function) analysis, the variability of NDVI in the region of higher latitude and altitude is higher than that in the other region since the spatial variability of NDVI follows the latitudinal gradient. Also we could get higher NDVI in June, July, August and September. We had the highest NDVI in Han-river basin area and the lowest in Je-Ju island.

Purpose: The current study was conducted in order to identify health and nutritional status of Korean underweight women in their twenties by comparing with normal, overweight, and obese women. Methods: Data from the 2010~2012 Korea National Health and Nutrition Examination Survey were used in this study. Subjects were 897 women aged 20~29 years. Subjects were classified according to underweight, normal weight, overweight, and obese groups based on body mass index. Health status was assessed using data from the health questionnaire and examination. Nutritional status was assessed using data from 24-hour dietary recall and a food frequency questionnaire. Results: The underweight group had higher education and exercised less than the obese group. Means of blood chemistry and blood pressure of the underweight group did not differ from those of the normal weight group. Means of fasting glucose, insulin, lipid profiles, blood cell counts, and blood pressure in the underweight group were different from those of the overweight or obese group. Proportions of delivery, breast feeding, and irregular menstruation in the underweight group were lower compared with the other groups. Except retinol intake, means of nutrient intake did not differ among four groups. There were significant differences among four groups in the intakes of cereals and eggs and frequency of consumption of dairy products. Conclusion: The current findings showed that health and nutritional status of underweight women in their twenties did not differ from those of normal weight women. In particular, health status of underweight women in their twenties was better than that of obese women of the same ages. Further study on health and nutritional status of extremely underweight women is necessary.

The purpose of this study was to vaccinate every year according to the general characteristics of COVID-19, whether to vaccinate every year according to the vaccination experience, whether to vaccinate every year according to knowledge/attitude about vaccination, and negative responses to the vaccinate every year In order to understand the factors affecting the vaccination physician every year by identifying the factors of Statistical analysis is based on general characteristics, variables based on vaccination experience, and knowledge/attitudes related to vaccination. The doctor calculates the frequency and percentage, A square test (-test) was performed, and if the chi-square test was significant but the expected frequency was less than 5 for 25% or more, a ratio difference test was performed with Fisher's exact test. Through multiple logistic regression analysis using variables that were significant in simple analysis, a predictive model for future vaccination and the effect size of each independent variable were estimated. As statistical analysis software, SAS 9.4 (SAS Institute Inc., Cary, NC, USA) was used, and because the sample size was not large, the significance level was set at 10%, and when the p-value was less than 0.10, it was interpreted as statistically significant. In the simple logistic regression analysis, the reason why they answered that they would not be vaccinated every year was that they answered 'to prevent infection of family and hospital guests' rather than 'to prevent my infection' as the reason for the vaccination. It was 11.0 times higher and 3.67 times higher in the case of 'for the formation of collective immunity of the local community and the country'. The adverse reactions experienced after the 1st and 2nd vaccination were 8.42 times higher in those who did not experience pain at the injection site than those who did not, 4.00 times higher in those who experienced swelling or redness, and 5.69 times higher in those who experienced joint pain. There was a 5.57 times higher rate of absenteeism annually than those who did not. In addition, the more anxious they felt about vaccination, the more likely they were to not get the vaccine every year by 2.94 times.

Neuroleptic malignant syndrome(NMS) is an acute, potentially fatal, idiosyncratic reaction to neuroleptic medication. Early recognition and intensive care are crucial. An important issue is whether NMS will recur after initial recovery and subsequent use of neuroleptic medication. The authors presented with a male adolescent who had suffered a bipolar disorder manic episode and been taking clozapine after recovering from MNS. He had been admitted into a psychiatric ward once before and similarly diagnosed. On the second admission, he showed muscle rigidity, autonomic instability, mild fever, severe diaphoresis, and altered mental status on the fourth hospital day following a haloperidol injection. He was diagnosed with NMS, according to the clinical signs and laboratory data. After the use of antipsychotics was discontinued, he was moved to intensive care unit and given dantrolene. His condition began to improve about 48 hours after the onset of NMS. Due to manic behavior, he returned to the psychiatric ward. On the 21 st hospital day, clozapine was administered to counter the manic symptoms. The final dose was 350mg and showed good remission signs without further recurrence of NMS.

A total of 32 human diphyllobothriasis cases have been reported so far in Korea, exclud- ing 21 egg-positive cases from stool examinations. Authors experienced five more human cases of DiphHllobothrium latum infection, especially infected due to eating raw flesh of redlip mullet, Lizc hoematocheiln. Five cases were neighbors residing in the Puchon area, Kyonggi-do, who ate raw mullets (L. hQematocheila) in a party in February 1996. The mul- lets were purchased at the Noryangjin fisheries market in Seoul. All of cases (2 males and 3 females) were 35 to 43 years old and healthy with the body weight range of 56-62 kg. They complained about gastrointestinal trouble and abdominal discomfort, but were in normal ranges of their hematology and urinalysis data. None revealed any sign of anemia The patients experienced natural discharge of a chain of segments before, and showed diphyllobothriid eggs in their stool specimens when they visited our laboratory. They were administered with praziquantel (15 mg/kg of body weight) and 30 g of magnesium sulfate as a purgative. Two whole worms with the scolices (310-340 cm in length; 8-13 mm in width) were expelled each from two out of five cases after anthelmintic treatment, and the others expelled the parts of strobilae without scolex. The worms were identified as D. Ictum, based on the following biological characters. external morphologies, coiling of uterus, the number of uterine loops, position of genital opening, morphologies of cirrus, cirrus sac and seminal vesicle on the histological sections, position of vagina and uterine pore , and microscopical and SEM morphologies of the eggs.

To measure the fertility rate and pregnancy wastage of women in rural area, 3,780 married women under 50 years old who were not sterilized either woman or husband in Gunwee county were followed up for 2 years. Seventeen Myun health workers visited these women periodically to check the status of their family planning practice and menstruation. Pregnant women were interviwed for their past obstetric history and followed up to the time of delivery. Family planning was practiced in 51.6% of the 6,826 women-years observed during the period from April 1, 1985 to March 31, 1987. Pregnancy, abortion and delivery covered 7.6% of the observed women-years and family planning was not practiced in 36.5% of the women-years. When sterilized women at the beginning of the study were included, the family planning practice rate was 72.1% which was slightly higher than the national family planning practice rate. However, 28% of the women of 30-39 years old had not practiced family planning although they had 2-3 children and they used more such less effective methods as safe-period method and condom than the women of 20-29 years old. Overall pregnancy rate was 14.3 per 100 woman-years. Women of 25-29 years old had the highest pregnancy rate of 27.4 per ,100 woman-years. Pregnancy wastage including spontaneous and induced abortions and still births was 22.0% of all pregnancies and it increased with the age of women; 15.8% in women less than 30 years old and 43.7% in women of 30 years and over. Women who terminated the pregnancy with induced abortion had more pregnancies, more previous induced and spontaneous abortions and shorter pregnancy interval than those women who terminated with live birth. Pregnant women terminated with a live birth had received 4.2 prenatal cares on the average. Eighty-five percent of deliveries occurred at a medical facility and 15% at home which was substantially lower home delivery rate than the other rural area of Korea. This may be due to the effects of the demonstration project for the primary health care in 1970s in Gunwee county. These findings suggest that family planning service in rural area should be strengthened by promoting the use of more effective contraceptive method among women over 30 years of age.

This study was performed to investigate the dietary habits, body weight satisfaction and eating disorder tendencies of female university students in Kyungnam province. Anthropometric measurements, dietary habits, body weight satisfaction, food preferences, disordered eating, and nutrient intakes were assessed in 132 female students at Kaya University. The results were analyzed with $x^2$- and ANOVA tests using the SPSS package program. The average age of the subjects was 20.1 years and average body mass index (BMI) were $21.1\;kg/m^2$. According to BMI, the percentages of students who were underweight, normal weight and overweight by BMI were 21.2, 55.3, and 23.5, respectively. Duration of exercise was significantly different by BMI. Index scores for a mini dietary assessment were significantly higher in the normal and overweight groups than in the underweight group. Scores for sweet, salty, and meat preferences were highest and scores for bean and vegetable preferences were lowest, in the underweight group. Satisfaction for present body weight was lowest, and self-perception of body image and weight control experiences were highest in the overweight group. All subjects in the overweight group wanted to be slim, and those in the normal and underweight groups, preferred to be more slim despite their current body weight being in the normal or below normal range. The percentage of the subjects who were at risk for eating disorders (based on scores from the Eating Attitude Test-26, EAT-$26{\geqq}20$) was 11.3%. Scores for EAT-26 were higher in the overweight group than in the underweight and normal weight groups. Nutrient intakes were not different among the groups. Therefore, dietary habits, taste and food preferences, satisfaction for present body weight, and disordered eating were significantly different according to BMI. These results suggest that overweight female university students need help correcting disordered eating, and nutrition counseling should be established to aid desirable weight control methods. Those who are underweight and normal weight need help establishing proper perceptions of their normal body weight and body image as well as nutrition counseling for health.
