Epidemiological situation of taeniasis in Mongolia was assessed based on mitochondrial DNA identification of the parasite species. Multiplex PCR was used on a total of 194 proglottid specimens of Taenia species and copro-PCR and loop-mediated isothermal amplification (LAMP) assays were utilized for detection of copro-DNA of 37 fecal samples from taeniasis patients submitted to the Mongolian National Center for Communicable Diseases (NCCD) from 2002 to 2012. In addition, 4 out of 44 calcified cysts in beef kept in formalin since 2003 were evaluated for histopathological confirmation of cattle cysticercosis. All proglottid specimens and stool samples were confirmed to be Taenia saginata by multiplex PCR and by copro-PCR and LAMP, respectively. Cysts collected from cattle were morphologically confirmed to be metacestodes of Taenia species. T. saginata taeniasis was identified from almost all ages from a 2-year-old boy up to a 88-year-old woman and most prominently in 15-29 age group (37%, 74/198) followed by 30-44 age group (34.8%, 69/198 ) from 15 of Mongolia's 21 provinces, while cattle cysticerci were found from 12 provinces. The highest proportion of taeniasis patients was in Ulaanbaatar, the capital of Mongolia.

The purpose of this study is to find out the influence of Home Economics learning on the recognition and attitude of middle school boy’s home life and to suggest the basic materials for the development of the Home Economics education through students’opinion of Home Economics. For this purpose, a survey was conducted in Cheong-ju area using questionaire. The subjects were 487 boys who studied Home Economics (HE group)and 480 boys who studied Technique (T group) in middle school. The statistics used for data analysis were t-test and x$^2$-test. The results of this study were as follows： 1. The recognition and attitude to home life on the general characteristics of home life； In urban area, the interests in bealth and the role of the consumers were higher than those of rural areas-on the bases of the standard of life, the middle class students had a higher interest in nutrition and food habits, the students whose father were engaged in special job had a higher interest in health and nutrition. 2. The difference of the recognition and attitude between HE & groups； In the field of food life, HE’s knowledge about the six nutrients and the basic food groups and attitude toward buying food were higher than T’s. In the field of family life and resources, HE and T accepted the importance of family life and the role of home as important, hoped to get psychological relax from home and to take the right sexual education. In the field of clothes life, HE and T had the general tendency to have their clothes in proper manner and to select their clothes for themselves, but HE took a higher interest in clothes mending and the role of clothes. 3. The opinions on Home Economics； HE answered that Home Economics was useful to them (more than 90% of HE) and that 57.1% of HE were interested in Home Economics. The order of interest among three fields were as follows： food life, clothes life, family life and resources. 71.9% of T hoped to take Home Economics course.

In the 2020s, the K-Pop market has been dominated by girl groups over boy groups and the fourth generation over the third generation. This paper presents methods and results on lyric clustering to investigate whether the generation of girl groups has started to change. We collected meta-information data for 1469 songs of 47 groups released from 2013 to 2022 and classified them into lyric information and non-lyric meta-information and quantified them respectively. The lyrics information was preprocessed by applying word-translation frequency vectorization based on previous studies and then selecting only the top vector values. Non-lyric meta-information was preprocessed and applied with One-Hot Encoding to reduce the bias of using only lyric information and show better clustering results. The clustering performance on the preprocessed data is 129%, 45% higher for Spherical K-Means' Silhouette Score and Calinski-Harabasz Score, respectively, compared to Hierarchical Clustering. This paper is expected to contribute to the study of Korean popular song development and girl group lyrics analysis and clustering.

Purpose: To analyze electrocardiograms (ECGs) of patients with a salt-losing tubulopathy (SLT) and to determine the frequency and risk factors for long QT and arrhythmia. Methods: A total of 203 patients aged <19 years with SLT, specifically Bartter syndrome and Gitelman syndrome, who had a 12-lead ECG were included in this retrospective study. We analyzed the presence of an arrhythmia or prolonged corrected QT (QTc) on ECGs obtained for these patients. Demographic and laboratory data were compared between patients with abnormal and normal ECG findings. Results: Out of the 203 SLT patients, 38 (18.7%) underwent electrocardiography and 10 (40.0%) of 25 patients with inherited SLT had abnormal ECG findings, including prolonged QTc and arrhythmias. The abnormal ECG group had significantly lower serum potassium levels than the normal group (median [interquartile range]: 2.50 mmol/L [2.20-2.83] vs. 2.90 mmol/L [2.70-3.30], P=0.036), whereas other serum chemistry values did not show significant differences. The cutoff level for a significant difference in QTc interval was serum potassium level <2.50 mmol/L. One cardiac event occurred in a 13-year-old boy, who developed paroxysmal supraventricular tachycardia and underwent cardiac ablation. No sudden cardiac deaths occurred in this cohort. Conclusions: The incidence of ECG abnormalities in patients with inherited SLT was 40.0%, whereas the ECG screening rate was relatively low (18.7%). Therefore, we recommend ECG screening in patients with inherited SLT, especially in those with serum potassium level <2.50 mmol/L.

Interstitial lung disease refers to a group of pulmonary disorders characterized by inflammation of the interstitium, derangements and loss of alveolar capillary units leading to disruption of alveolar gas exchange, which induces symptoms of restrictive lung disease. Cases of interstitial pneumonia in children are uncommon and mostly have unknown causes. We have experienced an 8-year old boy who had symptoms of cyanosis, dry cough, dyspnea and abrupt weight loss. He had not been exposed to organic dusts, allergens or any other systemic disease infections. Chest radiology showed diffuse ground glass opacity in both lung fields. High resolution computed tomography(HRCT) showed multiple small patchy areas of consolidation with an underlying ground glass appearance in both lungs. The pathologic findings of lung biopsy tissue showed patchy areas of interstitial fibrosis, alveolar obliteration and nodular fibrotic areas, strongly suggesting interstitial pneumonia. No specific finding of viral inclusion or any other evidence of infection was found under electromicroscopy. We used peak flow meters to compare functional improvement. Forced expiratory volume in one second ($FEV_1$) was decreased to 25 percent of predicted value. The boy was given treatment with prednisone and showed improvements in HRCT findings after two months. He was able to tolerate easy exercise in school and showed clinical improvements after one year of follow up.

Purpose: To investigate the long-term prognosis of patients with Kawasaki disease in Korea, and discuss the need for long-term follow-up. Methods: The subjects were 48 patients among 354 who had been hospitalized due to Kawasaki disease, and who consented to echocardiography and exercise challenge testing. The mean duration from the onset of disease to follow-up testing after rehospitalization was 11.6 years (8.2-17.0). Patients without coronary artery aneurysms at the initial presentation of the disease were classified in group 1, and patients with small aneurysms were in group 2. Test abnormalities and differences between the two groups were analyzed. Result: There were no significant differences in the results of follow-up echocardiography and exercise challenge testing between the two groups. Although no abnormal findings were noted at follow-up in most patients, a 9-year-old boy in group 2 showed coronary artery dilation. The exercise test indicated normal results in both groups, and echocardiography results were also normal in 100% of cases in group 1 and 93.3% of cases in group 2. Conclusions: As some patients with coronary aneurysms showed coronary artery dilation, we believe that long-term follow-up may be selectively required in patients with coronary artery complications.

The Purpose of this study was to identify calcium intake and cognition on calcium of adolescents in Busan area. Questionnaires including dietary habit, cognition on calcium, preference of calcium rich foods and diet record were developed. The questionnaires surveyed 285 adolescents consisted of 145 6th grade students (younger adolescents group, male: 72, female: 73) and 140 11th grade students (older adolescents group male: 66 female: 74). Adolescents appeared high cognition for function of calcium and milk but low cognition for nutrients related to absorption of calcium. Younger boy adolescents among them appeared the lowest score of cognition on calcium. The most preferred calcium rich foods in adolescents were ice-cream, laver and then yogurt whereas soybean and icefish dried appeared the lowest preference. Calcium intake of adolescents was 491.5~530.5 mg, 61.4~66.3% of RDA for Koreans, in female and 554.5~636.7 mg, 69.3~70.7% of RDA for Koreans in male. 64.9% of older girl adolescents showed calcium intakes under 66.7% of RDA for Koreans and this group also appeared less frequency of exercise than other group. Calcium intake of adolescents consisted of 44.6~53.3% from animal foods and 42.4~51.4% from plant foods. The adolescents consumed milk and milk products most, then vegetables and fishes as calcium source foods. Correlation analysis indicated that calcium intake was positively related to cognition on calcium of adolescents.

Toxic megacolon is a fatal complication of inflammatory or infectious bowel disease. Prognosis depends on the severity of the disease. In cases of poor prognosis, clinical outcomes range from intestinal resection to death, so early diagnosis and appropriate treatment are very important. However, the prevalence of toxic megacolon in children is very low, and in those without underlying diseases such as inflammatory bowel disease, early diagnosis may be delayed. A previously healthy 12-year-old boy presented to our hospital with lower abdomen pain, fever, and hematochezia. Despite antibiotic therapy, the symptoms worsened. On the third day, abdominal computed tomography revealed severe dilatation of the transverse colon, which indicated toxic megacolon. Stool culture was positive for Salmonella enteritidis group D, and rectal endoscopy showed no signs of inflammatory bowel disease. Ceftriaxone and intravenous methylprednisolone were administered, and the patient's condition improved without any complications. We report a case of toxic megacolon as a complication of infectious colitis caused by S. enteritidis group D, which was diagnosed using early imaging and successfully treated without surgical intervention.
