OBJECTIVE: The purpose of this study was to analyze current status of the web sites dealing with asthma in the Internet, and to evaluate their technical aspects and contents. METHODS: The evaluation tool consisted of four areas(construction, operation, accessibility, and content) with twenty-six items. Four sites including the contents related with symptoms of asthma, consultation of health professionals, and treatment and nursing for asthma were selected to be analyzed. RESULTS: The results of the analysis were as follows: 1) there was no web site dealing with asthma managed by public institutions 2) the only 5% of the top 100 sites were found to be related with the asthma by exploring the top five search engines in Korea and 3) the evaluation scores four web sites were 6-11 out of 18 in the category of construction, 10-21 out of 24 in operation, 5-10 out of 15 in accessibility, and 8-18 out of 21 in content. CONCLUSION: In conclusion, it will be possible to prevent asthma at first through web sites, which will be one of the most beneficial aspects of web site, so the system to evaluate web sites should be developed to provide high-quality information about asthma.

A new intravenous anesthetic agent, propofol reduces arterial blool pressure and reduces cardiovascular changes of tracheal intubation. The purpose of this study is to evaluate the effects of administration of thiopental 5 mg/kg and propofol 2.5 mg/kg on cardiovascular changes of tracheal intubation. Systolic arterial presure, diastolic arterial pressure, mean arterial pressure, heart rate and rate-pressure product were determined in healthy patients seheduled for tracehal intubation for general anesthesia before induction, after induction, 1, 3, and 5 minute after tracheal intubation. 1) After induction of anesthesia, above cardiovascular measurements except heart rate decreased significantly in both groups, but more profoundly in the propofol group. Heart rate did not change significantly in both groups. 2) Systolic arterial pressure, diastolic arterial pressure and mean arterial pressure increased significantly in the thiopental group after tracheal intubation, but decreased significantly in the thiopental group after tracehal intubation, but decreased significantly in the propofol group. After tracheal intubation, heart rate and rate-pressure product increased significantly in both groups, but the propofol group returned to the control value faster than the thiopental groups. In conclusion, in healthy adult patients, rise in the arterial blood pressure and heart rate after tracheal intubation decreased significantly in the propofol group compared with the thiopental group.

OBJECTIVE: The purpose of this study was to develop the decision tree models to classify the characteristics of those who had not undergone the health screening tests provided by the National Health Insurance Corporation. METHODS: Total of 5,102,761 subjects of health screening services in the year of 2002 was used. The data was divided into two data-sets (disease VS. non-disease group). The target variable was whether they took the health screening services. The number of input variables was 25 in total. RESULTS: The decision trees were classified into fourteen different types of non-examinees in the non-disease group and nineteen in the disease group. The ROC curve areas in the non-disease and disease groups were .761 and .714, respectively. CONCLUSION: The different types of non-examinees classified by the decision tree models would facilitate the foundation for the further analysis of individual characteristics and the effective health screening service management in future.

PURPOSE: The aim of this study is to evaluate the general status and prevalence of cerebral palsy, the complication and the activity of daily living in patients with cerebral palsy in Holt Ilsan Home. METHODS: Cross-sectional study was performed on 113 cerebral palsy patients in Holt Ilsan Home with the medical records review, the physical examination, and the Modified Barthel index for the independency of activities of daily living. RESULTS: The mean age of subjects was 28.1+/-12.7 years and the duration of residence was 22.9+/-12.8 years. The most common type of cerebral palsy according to the muscle tone abnormality was spastic type(53.1%). The most frequent condition in which extremities are involved were quadriplegia in 46.0%. The score of Modified Barthel index was significantly lower in mixed type for 16.9+/-24.0 and quadriplegic type for 14.8+/-25.5 compared with others. CONCLUSION: This study indicates that cerebral palsy patients in rehabilitation facility have severe medical problems such as musculoskeletal complications, visual and language problems, epilepsy and dependency in activities of daily living. Therefore more medical attention like long-term follow-up study and social supports is needed.

Purpose: : This study aims to identify the factors influencing field adaptation among nurses who have undergone department transfers, by examining the levels of and the relationships between their nursing work environment, interpersonal skills, grit, and field adaptation. Methods: : The study involved 137 nurses who had experienced at least one department transfer within the last three years across two hospitals. Data analysis was performed using SPSS/WIN 29.0, involving descriptive statistics, means, standard deviations, independent t-tests, one-way ANOVA, Scheffé post-hoc tests, Pearson correlation coefficients, and multiple regression analysis (enter method). Results: : Factors affecting field adaptation included the nursing work environment (β=.37, p ＜.001), interpersonal skills (β=.19, p =.021) and grit (β=.18, p =.025), with a total explanatory power of 31% (F=12.16, p ＜.001). Conclusion : This study contributes insights into effective nursing personnel management, offers foundational data for managing department transfers, and aims to improve the overall quality of nursing care.

Surgeries performed for patients with coronavirus disease 2019 (COVID-19) place the medical staff at very high risk of infection. We suggest recommendations for appropriate operation preparation, anesthetic management, and infection control for COVID-19 patients in operating rooms.Current Concepts: Surgeries must be performed in an airborne infection isolation room, such as a negative-pressure operating room. It is recommended that scheduled surgeries for COVID-19 patients be postponed to an acceptable extent, with the exception of emergency cases. Moreover, the number of medical staff participating in the surgery should be minimized. Medical staffs should practice proper hand hygiene and wear an appropriate level of personal protective equipment depending on the infection risk. While performing surgery and inducing anesthesia in COVID-19 patients, endotracheal intubation should be performed by trained anesthesiologists with a video laryngoscope, preferably using high-efficiency viral filters, which can prevent contamination in the anesthesia machine. Use of disposable equipment or COVID-19 patient-specific devices is recommended to prevent the spread of infection, but instruments that require sharing among multiple patients must be thoroughly cleaned and disinfected before their use for the next patient.Discussion and Conclusion: Medical staff performing surgeries for COVID-19 patients are at very high risk of infection. Therefore, the use of appropriate personal protective equipment, high-efficiency viral filters in breathing circuits during anesthesia, and disinfection of contaminated equipment after the operation are mandatory.

Extraskeletal chondromas are relatively uncommon benign cartilaginous tumors of the soft tissue and well known to pose a considerable diagnostic problem because of histological variations including the immature appearance of their tumor cells. Recently, we have experienced a case of extraskeletal chondroma mimicking benign chondroblastoma. The patient was a 47-year-old woman who complained of a painful subcutaneous swelling on the radial aspect of 4th proximal interphalangeal (PIP) joint in the left hand for 6 months. Radiologic examination of the 4th finger revealed a 1cm-sized soft tissue mass. Histologically, the tumor was characterized by a lobulated mass which was composed of dense proliferation of chondroblast-like cells admixed with a few multinucleated giant cells of osteoclastic type. However, there were focal areas of typical chondroma which showed lace-like intense calcification around the differentiated chondrocytes.
