Purpose: Chest radiography is often performed on patients hospitalized with typical clinical manifestations of bronchiolitis. We aimed to determine the proportion of subjects with pathologic chest radiographic findings and the clinical predictors associated with pathologic chest radiographic findings in young children admitted with the typical presentation of bronchiolitis. Methods: We obtained the following data at admission: sex, age, neonatal history, past history of hospitalization for respiratory illnesses, heart rate, respiratory rate, the presence of fever, total duration of fever, oxygen saturation, laboratory parameters (i.e., complete blood cell count, high-sensitivity C-reactive protein [hs-CRP], etc.), and chest radiography. Results: The study comprised 279 young children. Of these, 26 had a chest radiograph revealing opacity (n=24) or atelectasis (n=2). Multivariate logistic regression analysis showed that after adjustment for confounding factors, the clinical predictors associated with pathologic chest radiographic findings in young children admitted with bronchiolitis were elevated hs-CRP level (>0.3 mg/dL) and past history of hospitalization for respiratory illnesses (all P<0.05). Conclusion: The current study suggests that chest radiographs in young children with typical clinical manifestations of bronchiolitis have limited value. Nonetheless, young children with clinical factors such as high hs-CRP levels at admission or past history of hospitalization for respiratory illnesses may be more likely to have pathologic chest radiographic findings.

In this paper, we investigate a dynamic spectrum sharing problem for the centralized uplink cognitive radio networks using orthogonal frequency division multiple access. We formulate a large-scale joint rate and power allocation as an optimization problem under quality of service constraint for secondary users and interference constraint for primary users. We also suggest admission control to nd a feasible solution to the optimization problem. To implement the resource allocation on a large-scale, we introduce a notion of using the conservative factors $\alpha$ and $\beta$ depending on the outage and violation probabilities. Since estimating instantaneous channel gains is costly and requires high complexity, the proposed algorithm pursues a practical and implementation-friendly resource allocation. Simulation results demonstrate that the large-scale joint rate and power allocation incurs a slight loss in system throughput over the instantaneous one, but it achieves lower complexity with less sensitivity to variations in shadowing statistics.

Objectives : The aim of this study is to investigate the relevant factors which determine the use of oriental healthcare services among subjects with chronic illnesses. Method : This study utilized the data from the Korean National Health and Nutrition Examination Survey in 2005. Out of all the participants of the survey, 11,665 individuals who are older than 19 years old and have one or more chronic diseases were included in this study. Results : The factors that affect utilization of oriental healthcare services were significantly associated with gender, educational level, job, personal income, the number of chronic illnesses, experiences of nontreatment or delayed treatment and admission experiences for the last one year(p<.001). Although some of these factors need further studies, the determining factors for the use of oriental healthcare services are the presence of chronic illness and the number of chronic disease. That is, the chronically ill are more likely to seek oriental healthcare services. And the more chronic diseases the clients have the higher probability of seeking oriental healthcare services was found. Conclusions : The results suggest that the national integrated care services should be established for diverse development of policy regarding the quality of care of chronic illness and cost-effectiveness.

Purpose: A nationwide outbreak of Mycoplasma pneumoniae pneumonia (MP) refractory to macrolide antibiotics occurred in Korea during 2011. Steroid therapy has been reported to be both efficacious and well tolerated in pediatric patients with refractory MP. We compared clinical features and laboratory characteristics between children with refractory MP requiring steroid treatment and those with macrolide-responsive MP and evaluated the risk factors associated with refractory MP. Methods: We investigated 203 children who were admitted to our institution with MP from June to November 2011. Refractory MP was defined by persistent fever over $38.3^{\circ}C$ with progressive pulmonary consolidation or pleural effusion despite administration of appropriate macrolide antibiotics for 5 days or longer after admission. Steroid therapy was initiated on the fifth day after admission for refractory cases. Results: There were 26 patients with refractory MP requiring steroid therapy. The mean duration of steroid therapy was 5.4 days and most of the patients were afebrile within 24 hours after initiation of steroid therapy. The prevalence of refractory MP was higher in patients with pleural effusion, lobar pneumonia affecting more than 2 lobes, higher levels of serum lactate dehydrogenase, increased oxygen requirements, and longer duration of hospitalization. Atopic sensitization and history of asthma were also associated with refractory MP after adjusting for age and gender. Conclusion: Children with refractory MP had more severe pneumonia. Atopic sensitization and history of asthma may be risk factors for refractory MP requiring steroid therapy in Korean children.

This study investigates general environmental factors influencing hypertension and diabetes patients and their disease control methods, self-efficacy, nutritional risk, diagnosis of eating styles according to nutritional risk, accountability in eating habit instructions, and nutritional intake and provides basic data for eating habit control in hypertension and diabetes patients. For this, 70 patients who visited a hypertension and diabetes admission center were interviewed using a questionnaire. According to the results, the implementation of self-efficacy in hypertension and diabetes was higher in female subjects. The diagnosis of eating type with nutritional risk was higher in female subjects, and there was a significant difference between male and female subjects (p<0.05). Both sexes had scores above 6 in nutritional risk and were diagnosed to have a "high-risk nutritional status." In the diagnosis of eating habits with nutritional risk, diet quality was higher for female patients (p<0.05), and the nutritional intake of subjects was low for most nutrients. In particular, the intake of calcium, vitamin A, riboflavin, and folic acid was low, indicating a need to improve eating habits for the balanced intake of nutrients because of the increasing importance of eating habits for controlling chronic diseases.

Purpose: Poisoning is a major health problem for the elderly, and poisoning can cause fatal side effects. However, the characteristics and clinical features of elderly patients with acute poisoning have not been well studied in the previous domestic research. So, we tried to analyze the clinical characteristics and toxic substances of the patients who were 65 years old or older and who were admitted to the regional emergency medical center due to acute poisoning. Methods: We retrospectively reviewed the medical records and poisoning protocols of the patients who were 65 years of age or older and who had with acute poisoning and who visited the ED in our emergency center from January 2005 to December 2009. We collected the demographic information, the gender, the underlying diseases, the causes and toxic substances, the initial presentation, the treatment and the outcomes. Results: A total of 2179 poisoned patients visited the hospital during 5 years, and among them 244 were 65 years of age or older (11.2%). The mean age was $75.6{\pm}6.9$ years and the male:female ratio was 1:1.7. The most common cause of poisoning was suicide (73.4%) and the most common source of poisonous substances was their own drugs. Of the substances used for poisoning, benzodiazepine was the most common drug (25.8%), followed by sedatives other than benzodiazepine (25.4%), insecticide (12.7%), chemical agents (12.3%) and herbicides (8.2%). The most common initial presentation was mental change (64.8%). When comparing the factors between the three elderly groups, there was no difference in gender, the cause, the substances and the underlying disease. The outcomes of treatment included ICU admission (56.1%), a good condition at discharge (12.7%) and admission to a general ward (12.7%). The overall mortality rate was 10.2% for the elderly patients. Conclusion: In this Korean study, unlike the foreign studies, the most common cause of poisoning in elderly patients was intentional poisoning. The admission rate was 68.8% and mortality rate was 10.2%.

The purpose of this study was to know the state of rehabilitation treatment of stroke, to compare treatment with Bobath therapy or not, establish what factors have influence on treatment effect and hospitalization period and to be a great help for guide of treatment and education of patient and family We analyzed 87 stroke patients retrospectively for the patient's age, the subtype of diagnosis, the period at the start of treatment, the duration of treatment, the duration of hospitalization, the speech problem the co-morbid complication and the ambulatory function at discharge These patients visited the department of rehabilitation medicine, Holy Family Hospital, Catholic university of Korea from June 1993 to June 1998. The patients were classified into two groups. One group (47 patients) was treated by Bobath trerapy and the other (40 patients) was not. The results were as follow ; 1) The period at the start of treatment was 15.3 days and the duration of treatment was 32.4 days 2) The shorter the period at the start of treatment, the shorter the duration of admission 3) There was no significant difference between two groups for the duration of hospitalization, seventy two percent of patients with Bobath treatment was walked compared with 25% of patients without Bobath treatment was. 4) There was no relation between the speech problem and the duration of admission, but the group with no speech problem showed better results in ambulation than those with speech problem. On conclusion, as soon as possible early rehabilitation treatment of the stroke patients should be performed in order to reduce the duration of hospitalization. Special(or professonal) treatment with Bobath therapy show more improved funtional recovery than that without Bobath therapy. Therefore actualization of Bobath therapy is also required.

Objective : To determine the presentation, incidence, and risk factors of seizures in patients treated for brain tumors. Methods : One hundred patients who consecutively underwent a craniotomy for the treatment of supratentorial brain tumors were assessed. The pathologies of the patients enrolled in the study included glioma [n=56], meningioma [n=31], metastatic brain tumor [n=7], primary central nervous system lymphoma [n=4], and central neurocytoma [n=2]. Anti-epileptic drugs [AEDs] were administered to all patients for up to six months after the surgery. Pre-defined variables for outcome analysis included tumor grade and location, extent of tumor resection, number of seizures, age at tumor diagnosis, adjuvant therapy, medication and radiological abnormalities. Results : Thirty patients [30%] presented at least a single episode of seizure at the time of admission. Five of these patients [16.7%] developed the seizure during the follow-up period. Newly developed seizure was noticed in six out of seventy patients [8.6%] without prior seizure. Histopathology was malignant gliomas in 10 and supratentorial meningioma in one. Early seizure developed only in two patients. Conclusion : Compared with patients without seizure, patients with seizure at the time of admission showed younger age [p=0.003], a higher portion of low-grade glioma [p=0.001], tumor location in the frontal and temporal lobes [p=0.003] and cortical involvement [p=0.017]. Our study suggestes that tumor progression is considered a significant risk factor for seizure development in glioma patients.
