Seasonal fluctuations of Riptortus pedestris were investigated in four regions including two sites each at Mt. Yangseong (Munui-myeon, Cheongwon-gun), O-chang (Cheongwon-gun), and Jujung-dong (Cheongju) using aggression pheromone traps from April to November in 2010 and 2011. Aggression pheromone and aggression pheromone + soybean traps were set at all investigated sites, and the Mt. Yangseong A and B sites were investigated at a farmland (80 m, asl) and forest (200 and 300 m). The population density of R. pedestris was high in mid June, mid August, and late October in 2010 and in early May, mid June, mid September, and early October in 2011 with trivoltine. O-chang and Jujung-dong populations, which were distinguished in farmlands and forests, were highest from June to August in the farmland and in September in the forest. Similar numbers of R. pedestris were capture in the farmlands and the forest in June-August, September-November, respectively. From the results of the four regions, more R. pedestris adults were captured in the aggression pheromone + soybean trap than that in the pheromone trap. To investigate the migration route by altitude, 500 R. pedestris adults marked with fluorescent paint were released and re-caught insects were counted in traps after 10 and 20 days. The pattern of the re-caught R. pedestris indicated migration from the forest to farmlands during April-June. These results suggest that the insects did not migrate in August because food was plentiful in the forest at 200 m, but they moved to the forest during October due to the scarcity of food and for overwintering. The R. pedestris seasonal fluctuations in 2011 were affected heavily by the environment, particularly rain precipitation.

The nephrotic syndrome is characterized by generalized edema, hypoproteinemia(<2 g/dL), proteinuria(>40 $mg/m^2/hr$), and hypercholesterolemia(>200 mg/dL). It is reported that hypoalbuminemia, which is one of the four diagnostic criteria of the nephrotic syndrome, is associated with gallbladder wall thickening. An explanation for the thickened wall in hypoalbuminemic states is the accumulation of fluid in the subserosal layer of the gallbladder wall which contains the most areolar tissue. This report describes a patient who was initially diagnosed with the nephrotic syndrome at the age of 4 and subsequently developed acute acalculous cholecystitis at the age of 5.8 with an albumin level of 1.3 g/dL. The patient responded to fluid therapy, nasogastric suction, and broad spectrum antibiotics.

목 적 : Mycoplasma pneumoniae 폐렴은 소아 및 청소년기에 주로 호흡기 질환을 일으키는 주요 원인이다. M. pneumoniae 폐렴을 진단하기 위해서는 한랭응집소 검출반응, 마이코플라즈마 특이 항체 측정법, 배양 검사 등의 방법이 이용되고 있으나 초기 진단에는 효용성이 떨어진다. 본 연구는 중합 효소 연쇄반응과 효소면역측정법을 이용한 M. pneumoniae 폐렴의 진단적 유용성에 대해 평가하고자 하였다. 방 법 : 연세대학교 의과대학 부속 세브란스병원 및 영동세브란스병원 소아과에 입원한 환자 중 입원 당시 시행한 흉부 X-선 검사 및 흉부 청진상 폐렴 소견을 보인 환아 111명의 임상 검체를 대상으로 M. pneumoniae를 분리, 동정하였다. 마이코플라즈마 특이항체가 1 : 320 이상이거나 추적 관찰 시 4배 이상 역가가 증가하는 경우를 M. pneumoniae 폐렴으로 진단하였고 이를 기준으로 중합 효소 연쇄반응과 효소면역측정법을 수행하였다. 결 과 : 중합 효소 연쇄반응의 민감도는 40.6 %, 특이도 63.3%, 위양성률 69.1%, 위음성률 27.5%로 나타났고, 효소면역측정법에서 M. pneumoniae 특이 IgM은 민감도 9.4%, 특이도 100%, 위양성률 0%, 위음성률 26.9%를 나타내었다. 중합 효소 연쇄반응과 효소면역측정법을 조합한 결과는 민감도 46.9%, 특이도 63.3%, 위양성률 65.9%, 위음성률 25.4%로 나타났다. 결 론 : M. pneumoniae 폐렴의 진단에 있어서 미세입자 응집법을 이용한 특이항체 검사와 더불어 중합 효소 연쇄반응과 효소면역측정법을 시행함으로써 보다 정확한 진단을 할 수 있을 것으로 사료된다. Purpose: Mycoplasma pneumoniae is a common respiratory pathogen responsible for acute respiratory infections in young children. The standard laboratory methods for the specific diagnosis of M. pneumoniae infection have been isolation in culture and serological methods. The objective of this study was to compare the performance of enzyme-linked immunosorbent assays (ELISA) for the detection of M. pneumoniae specific IgG and IgM antibodies and polymerase chain reaction (PCR) in diagnosis of M. pneumoniae pneumonia. Methods : For a 1-year period, 111 patients admitted to Severance Hospital and Yong-dong Severance Hospital with clinical features of pneumonia and radiographically defined pneumonia were included. Serum specimens and throat swab specimens were obtained at the time of admission. Patients who showed M. pneumoniae antibody titer 1 : 320 or greater or a fourfold increase in M. pneumoniae antibody titer between acute and convalescent sera obtained 5 days to 3 weeks after the onset of illness were diagnosed as having M. pneumoniae pneumonia. PCR and ELISA were also performed. Results :The sensitivity, specificity, false positivity, and false negativity of PCR were 40.6 percent, 63.3 percent, 69.1 percent, and 27.5 percent, respectively. The sensitivity, specificity, false positivity, and false negativity of ELISA IgM were 9.4 percent, 100 percent, 0 percent, and 26.9 percent, respectively. The sensitivity, specificity, false positivity, and false negativity of the use of PCR and ELISA in combination were 46.9 percent, 63.3 percent, 65.9 percent, and 25.4 percent, respectively. Conclusion : These observations suggest that the use of PCR and ELISA in addition to the detection of serum antibody to Mycoplasma pneumoniae using microparticle agglutination would allow the maximal number of diagnoses to be made at a very early phase of infection.

Purpose : $Henoch-Sch\"{o}nlein$ purpura(HSP) is a systemic vasculitis that involves multiple organs, especially the kidney, which is the most important organ in determining the prognosis of the disease. The morbidity of HSP nephritis in adults is low and there have been little research done on its clinical course so far. Therefore, we have compared the clinical course of HSP nephritis in children and adults in Korea. Methods : We retrospectively analyzed 81 cases of HSP nephritis in children younger than 15 years of age, and 25 cases of adults older than 15 years of age who were admitted to Yonsei University Medical College Severance Hospital from Jan. 1986 to May 2003. Results : The male to female ratio was 1.5 : 1 in children and 1.3 : 1 in adults. The incidence of HSP nephritis for both age groups was found to be increased during the autumn and winter. Infection was the predisposing factor in 39 cases(48.1%) of children, 16 cases(64.0%) of adults, and drugs were the predisposing factor in 8 cases(9.9%) of children and 4 cases (16.0%) of adults. All patients initially presented with microscopic hematuria. Thirteen cases (16.0%) of children and 7 cases(28.0%) of adults initially showed proteinuria of nephrotic range. Thirty four cases(42.0%) of children and 4 cases(16.0%) of adults showed normal urinalysis after treatment. Asymptomatic urinary abnormalities were found in 41 cases(50.6%) of children and 18 cases(72.0%) of adults. Complications such as nephrotic syndrome and hypertension were found in 3 cases(3.7%) of children and 2 cases(8.0%) of adults. Three children(3.7%) and 1(4.0%) adult required dialysis or renal transplantation. Follow-up renal biopsies were performed on 21 children, of whom 10 cases(47.6%) did not show any histologic change, 9 cases(42.9%) showed low grade changes, and 2 cases(9.5%) showed high grade changes. Prognosis was gloomy when proteinuria of nephrotic range and high grade of abnormal histology were present at diagnosis, and there was no significant difference between the two groups(P<0.05) Conclusion : This study showed that there was no difference in terms of the clinical features and courses between the children and adults with HSP nephritis. Proteinuria of nephrotic range and the severity of abnormal histologic changes at diagnosis were found to be associated with a bad prognosis, therefore we recommend that patients with these features require long term follow-up and management.

This study aims to present the effectiveness of using Geographic Information System(GIS) in the marketing for sports centers and find out the utilization methods by analyzing the requirements needed for sports-related marketing on GIS and comprehend the problems on spatial data. Through the precedent researches on the location of sports facilities and the analysis of service zones, and case studies of marketing application utilizing GIS, this study implemented visualization of distribution of sports facilities, service zones and their competition states. Also, this study proved the fact that sports facilities can be properly distributed, in order to induce active utilization of GIS to sports marketing strategies. As a result of this study, following utilization methods of GIS were suggested. First, mapping the current location of sports center customers through collecting customer data and coordinate transformation of address; Second, identifying the boundary of primary, secondary and tatiery service zones by the application of spatial mutual working model; Third, grasping approach to the sports centers through range; Fourth, grasping the location having potential customers using population geographic data; Fifth, specifying goal market of sports center using data of each stage. However, in order to reflect requirements for spatial decision making of a company, it is required to set up and distribute socioeconomic data considering data aspects required for GIS application in business field. For the purpose, further researches should be made as well.

소아에서 폐기능검사

Pulmonary function testing (PFT) is an important and fundamental method in the evaluation and treatment of respiratory diseases. Airway responsiveness assessed using histamine or methacholine by PFT is meaningful for the diagnosis of asthma. Spirometry is simple, and has been the most commonly used technique. However, in younger or uncooperative children, other commercially available tools such as impulse oscillometry (IOS), gas dilution, and plethysmography have been used. IOS is a noninvasive method that allows the measurement of airway mechanics (resistance [R] and reactance [X]) with minimal patient cooperation. Functional residual capacity (FRC) is one of the most important measurements obtained by gas dilution. Plethysmography is a gold standard to measure airway resistance and useful for lung function testing in infants. The purpose of this review is to help pediatric physicians being familiar with PFT techniques used in young children by discussing their principles, clinical applications, limitations, and current accessibility in Korea.

Purpose: It is well known that respiratory viral infection has epidemiological characteristics, including season. This study aimed to investigate the patterns of the prevalence of common respiratory viruses during a period of 10 years with regard to age, sex, and season in Korean children. Methods: From June 2006 to November 2016, we obtained 11,798 specimens from patients aged less than 18 years who were admitted with lower respiratory infections. Ten respiratory viruses were detected using multiplex reverse transcription-polymerase chain reaction. Results: Of 11,798 specimens, at least 1 virus was detected in 4,845 (41.1%). Respiratory syncytial virus (RSV, 18.9%) was the most common virus detected, followed by human rhinovirus (HRV, 14.8%), adenovirus (9.5%), and human bocavirus (HBoV, 7.4%). The detection rate of HRV was higher in male subjects (male 60.0% vs. female 40.0%, P=0.004), but the other viruses had no significant differences with regard to sex. The subjects who were positive for RSV test were youngest (median, 10.5 months; interquartile range, 3.0-25.0 months), followed by human coronavirus (median, 13.0 months), HRV (median, 14 months), and parainfluenza (median, 14 months). HBoV was most commonly detected in spring (29.3%), enterovirus in summer (25.8%), HRV in fall (22.6%), and RSV in October and winter (22.6%). Conclusion: We found that the prevalence of respiratory viruses in Korean children during a period of 10 years was associated with age, sex, and season when the infection occurred. Further nationwide data is warranted to infer clinical implication of our results. (Allergy Asthma Respir Dis 2017;5:320-325)

The hygiene hypothesis, first proposed in 1989, suggested that reduced exposure to infections in early life leads to allergic diseases by the defects in the establishment of immune tolerance. Although many studies provided evidence that some exposure conditions, including family size, antibiotics, probiotics, and viral or bacterial infections, are strongly related to the prevalence of allergic diseases, thereby supporting the hygiene hypothesis, some evidence does not provide acceptable results for the hygiene hypothesis. Further, most studies have focused on patients with asthma or atopic dermatitis, not allergic rhinitis. In this review, we summarize the recent studies for and against the 'hygiene hypothesis' and identify causal association with the prevalence of allergic rhinitis.
