Purpose: The objective of this study was to identify the significance of 24-hour post-reduction ultrasonography (US) in pediatric patients with intussusception. Methods: A total of 229 patients with intussusception who were treated with saline reduction at Severance Children's Hospital between January 2014 and September 2020 were retrospectively reviewed. The 229 patients with successful saline reduction were divided into two groups: a recurrence at 24 hours group (R, n=41) and a non-recurrence group (NR, n=188). The full patient sample was divided into two groups: follow-up US (FU) or no follow-up US (NFU); the recurrence group was divided into follow-up (R-FU) and non-follow-up (R-NFU) subgroups, and stratified analyses were performed. Results: There were no significant differences in age, sex, laboratory findings, symptoms, and sonographic findings between the NR and R groups. In the R group, 24 patients underwent follow-up US, and 17 patients did not. Specific sonographic findings were statistically significant in the R-FU group compared to the R-NFU group (p=0.002). The R-FU group had fewer admissions (p=0.012) and longer mean hospitalization times (p<0.001) than the R-NFU group. The NFU group had a 12.2% recurrence rate, while the R-FU group recurrence rate was 25.8% (p=0.0099), suggesting that the omission of some recurrent events and follow-up US was a significant variable in the recurrence of intussusception. The median time to recurrence was 21 hours which supports the 24-hour follow-up protocol. Conclusion: Twenty-four-hour follow-up US was shown to be valuable for detecting early recurrence of intussusception.

Purpose: The purpose of this study was to investigate the guardian's experience about tepid massage of children who visited Pediatric Emergency Room (PER). Methods: Data for this study was collected from August 1 to September 30, 2009 using questionnaires of 300 guardians who visited a PER. All data analyses were done using the SPSS 17.0 program and statistical data on frequency and percentage were obtained. $x^2$ test was done as well. Results: The results of this study were as follows: 73.7% of the guardians were doing the tepid massage, and 40% of them were doing the tepid massage when guardians thought that their children had a fever. 8.6% of them were incorrectly doing the tepid massage on their children such as using ice or alcohol. 90.5% of the children's condition changed when they had the tepid massage applied. Only 48% of the guardians got information about tepid massage, and 52.8% of the guardians got this information from the medical team. There were significant differences according to the education background about tepid massage (p<.001) and past hospital admissions history. There were differences according to whether their child had experience with febrile seizure(p=.085) and having more than one child at home (p=.085). Conclusion: This study revealed that the guardians were incorrectly doing the tepid massage on their children. The results of this study suggest that it is necessary to develop certain emergency nursing processes on accurate information and management strategies about tepid massage, and further studies on the effects of this kind education intervention are necessary.

Purpose: This study is a descriptive research intended to clarify the medication status of community-dwelling elders and to identify factors affecting their medication adherence. Methods: Data were collected using questionnaires and interviews from 101 subjects who had taken prescribed drugs for at least 7 days sampled among elderly people using home care nursing at a general hospital in Seoul. Results: According to the results of this study, medication adherence measured by pill counting was 88.3% and that measured by self-reporting was 94.6%. There were statistically significant differences in medication adherence according to major disease (p=.006), the number of admissions (p=.032), the number of drugs (p=.051), the frequency of medication (p=.026), and depression (r=-.205). In addition, depression was found to be a significant variable explaining the medication adherence with explanatory power 3.8% (p=.035). Conclusion: The presence of depression affected the elderly subjects' the medication adherence. Therefore, more concern and educational approaches are required to encourage elderly people to comply correctly with medication regimens particularly for elderly patients who have a malignant or long-lasting disease or who have to take multiple drugs or maintain a daily dosing frequency.

이 논문에서는 장기억 과정에서의 변화점을 빨리 검출하는 베이지안 추론방법에 대해 알아본다. 장기억 과정에서의 베이지안 추정은 장기억 모수값에 따라 전체 자료에 대한 부분차분을 계산해야 하기 때문에 수행시간이 많이 걸린다는 문제가 있다. 이 논문에서는 이러한 문제를 해결하고자 장기억 모수공간을 그룹화하여 순서형으로 범주화시킨 후 설명력이 가장 높은 범주의 대표값을 선택하게 하였다. 이 방법은 초기단계에서 범주의 대표값에 대해 한번씩만 부분차분을 계산하면 되기 때문에, 매번 계산해야 하는 추정하는 방법보다, 특히 시계열자료의 수가 많은 경우, 상대적으로 빠른 베인지안 추론이 가능하다. 또한 장기억 모수공간이 (0,0.5) 이기 때문에 모수공간을 적절하게 그룹화한다면 장기억 모수를 선택하는 것이 모수를 추정하는 것에 비해 큰 차이가 없다. 이 논문에서는 나일강 수위자료 실증분석을 통해 제안된 방법의 타당성을 확인해본다.

Objectives: We estimated the asthma-related health care utilization and costs in Korea from the insurer's and societal perspective. Methods: We extracted the insurance claims records from the Korea National Health Insurance claims database for determining the health care services provided to patients with asthma in 2003. Patients were defined as having asthma if they had ${\geq}$2 medical claims with diagnosis of asthma and they had been prescribed anti-asthma medicines, Annual claims records were aggeregated for each patient to produce patient-specific information on the total utilization and costs. The total asthma-related cost was the sum of the direct healthcare costs, the transportation costs for visits to health care providers and the patient's or caregivers' costs for the time spent on hospital or outpatient visits. Results: A total of 699,603people were identified as asthma patients, yielding an asthma prevalence of 1.47%. Each asthma patient had 7.56 outpatient visits, 0.01 ED visits and 0.02 admissions per year to treat asthma. The per-capita insurance-covered costs increased with age, from 128,276 Won for children aged 1 to 14 years to 270,729 Won for those aged 75 or older. The total cost in the nation varied from 121,865 million to 174,949 million Won depending on the perspectives. From a societal perspective, direct health care costs accounted for 84.9%, transportation costs for 15.1 % and time costs for 9.2% of the total costs. Conclusions: Hospitalizations and ED visits represented only a small portion of the asthma-related costs. Most of the societal burden was attributed to direct medical expenditures, with outpatient visits and medications emerging as the single largest cost components.

Purpose: The aims of this study were to describe general characteristics and needs of home health care, and to find the differences between home health care needers and non-needers. Method: In this study, 642 subjects participated who lived in Muan, Jollanam-do. Data were collected in August 2001 using a self-reported questionnaire. The questionnaire was a revised and simplified form of the Organization of Community Health System Program at the Seoul National University. Collected data were analyzed through Kruskal-Wallis test. t-test. and Chi-squire for cross-sectional analysis. Result: The average age of the subjects was 52.6 years and 33.3% of them aged over 65 years. Twenty six percent of them had chronic degenerative diseases. The percentages of hypertension patients and D.M. patients were 6.4% and 2.5%, respectively. The number of family members was 2.95 on the average, 2.19 in cases of families with the elderly and 3.33 in cases of families without the elderly. The rate of disability of the elderly was 10.5%. Marital status (p=.000), the number of family members (p=.000), education (p=.000), job (p=.000) and health insurance (p=.027) were significantly different between home care needers and non-needers. Home care needers had less living expenses (p=.001), more frequent hospital admissions (p=.004), higher chronic disease rate (p=.000) and more frequent visits to public health center (p=.027) than non-needers. Home care needers who wanted free service were twice as many as non-needers. Conclusion: Home care need was very high in rural areas and the needers had worse characteristics (low educational level. low income, no job and no family). Therefore, it is necessary to develop cheaper and more accessible services for home care needers in rural areas.

Lately human exposure to fine particles smaller than $2.5{\mu}m$ in aerodynamic diameter ($PM_{2.5}$) has become a great concern in Korea due to their possible cause of elevated mortality, lung function decrements, and more frequent hospital admissions for asthma. This study was conducted to investigate seasonal variations of human exposure to residential $PM_{2.5}$ and particle-associated polycyclic aromatic hydrocarbons (PAHs). Ten homes in Chuncheon, Korea were visited for continuous 72 hour sampling of $PM_{2.5}$ in the living rooms using a MiniVol Portable Sampler from December 22, 2002 to November 3, 2003. During the same period, outdoor $PM_{2.5}$ samples were collected on the top of the Natural Sciences Building of Kangwon National University which is located in the middle of the ten households. Samples were analyzed for $PM_{2.5}$ mass concentrations and six selected PAHs. In two smoking homes, the highest $PM_{2.5}$ concentrations were measured ranging from 51.1 to 69.7 {\mu}g/m^3$ on average in all seasons, indicating smoking is a very important contributor to the elevation of indoor particle concentrations. Seasonal comparison showed that indoor particle concentrations were higher than outdoor ones except winter. Total PAH concentrations in smoking homes were highest in winter among the seasons primarily due to low ventilation rate, followed by the outdoor site and nonsmoking homes. BaP toxic equivalents (TEQs) were calculated for five PAHs. The TEQ for smoking homes in winter was highest followed by the outdoor site in winter. It is concluded that smoking and ventilation rate are two important contributors to the elevation of indoor $PM_{2.5}$ and PAH concentrations.
