Today, Korean medical community faces rapid changes in medical environment due to opening of medical market, more emphasis on making profit and introduction of private medical insurance. Therefore, it is apparent that around, major university hospitals, efforts are being made to adapt to such changes by establishing mid to long range strategic plans. We want to keep pace with changing times and diverse demand of patients by introducing state of the art system, utilizing Ubiquitous technologies for improvements. In doing so, we want to distinguish our hospital services from others. However, Hospital Information System that integrates ubiquitous technologies are introduced in limited basis due to problems like standardization and limits on medical use etc. Particularly, problems like absence of tag design suitable for medical environment, compatibility and extension issue with RFID system need to be addressed on application of RFID technologies. In order to solve such problems, this paper implemented RFID tag system, RFID-SIP UA program, location tracking program. This paper provides a comprehensive basic review of RFID and SIP model suggests the evolution direction of further advanced RFID application service. The design of RFID-SIP application offers advance RFID system with drawback and reduction search time of medical object. so there is a improvement of hospital information system in ubiquitous environment.

Thirty six patients, female 21(58.4%), male 15(58.4%), with centipede bite visited emergency room of Gimcheon Medical Center, from September 1998 to August 1999. The number of patients accompanying the seasons were increased once in June and were high in August and September; peaked in September, which conforms to the habitude that centipede likes the warmer climate. Frequency accompanying the time was high after sunset(from 6 p.m. to 6 a.m. next morning) than before sunset, which conforms to the habitude that centipede is nocturnal. Distribution of the bite sites was finger(30%), neck(28%), foot(25%) and hand(14%) as same as the previous researches showed. In case of finger and hand, patients got bitten while they were wearing gloves or doing works; foot, wearing shoes. They got bitten the neck while sleeping. Among the localized symptoms were localized pain: 36 patients(100%), swelling: 36 patients(100%), erythema: 26 patients(72.2%), paresthesia: 5 patients (13.9%). Systemic symptoms were dizziness 2 patients(5.6%) and nausea 1 patient(2.8%). Mostly the localized pain was improved within 48 hours, swelling in 48 hours and within 72 hours in case of paresthesia. Systemic symptoms such as dizziness and nausea were improved within 24 hours. Treatment and prognosis of scolopendra have similarity in many countries. We suggest that Korean standard treatment manual is needed so that the localized symptom, systemic symptom and external wound can be cured soon.

The purpose of this study was to identify relationships between the awareness of well-dying, advance directives knowledge and attitude, according to patient's terminal care experience among nursing students. Participants were 321 nursing students, selected from 3 universities located in Gyeonggi-do, Chungcheong-do, Jeolla-do and data were collected using self-reported questionnaires. Data were analyzed using the SPSS/WIN 25.0 program, with descriptive statistics x²-test, t-test, ANOVA, Scheffe' test, Pearson's correlation coefficient. There was a significant difference in advance directives attitude among nursing students with experience of patient's terminal care or no experience of patient's terminal care (t=3.011, p<.003). In addition, the awareness of well-dying (r=.194, p=.008) and advance directives knowledge (r=.201, p=.006) were positively correlated with advance directives attitude in nursing students with experience of patient's terminal care, whereas advance directives attitude was positively correlated with the awareness of well-dying (r=.189, p=.029) in nursing students with no experience of patient's terminal care. This study suggests that there is a need for the development of systematic education programs to improve a positive attitude toward advance directives and awareness of well-dying of nursing college students.

Urinalysis is considered to be easier and simpler than other tests. It has been known to cause no burden to patients, while offering important information on diagnosing, treating, and determining the prognoses of kidney and urinary tract diseases. Urinary sediments are usually performed by microscopic examination of centrifuged urine by technologist. The guidelines proposed by the Korean Association of External Quality Assessment Service are actually different from those actually practiced by medical institutions and taught to biomedical students in textbooks. Therefore, we verified whether different sediment preparation methods lead different test results. Specimens that tested positive from the occult blood and leukocyte esterase in the urine dipstick test were randomly selected for a microscopic examination. The differences in the urine sediment preparation affected the sediment concentrations, which influenced the cell grade and cell number per HPF. The first factor in determining the sediment concentration is the centrifugal force. Many medical institutions use 1,500 rpm as the centrifugal speed without considering the radius of the centrifuge; such a value may not be accurate for 400 G. Consequently, there were differences in urine concentrations, which influenced the results. The second factor is the amount of sediment in urine. Different amounts of the remaining supernatant led to different sediment concentration factors, again, causing different results. Furthermore, not only by using a pipette to obtain an accurate amount as stipulated, but also by roughly obtaining a drop, the microscopic examination using such a volume of sediment examined affected the results. Therefore, this study highlights the importance of standardization of urine sediment preparation procedures to promote consistency and accuracy across institutions.

Background : DNA fingerprinting of Mycobacterium tuberculosis with RFLP is a very useful tool for deciphering the molecular epidemiology of tuberculosis. An international comparison of the RFLP pattern became possible with the proposal to standardize RFLP methodology using Pvu-II restricted IS-6110, and the comparison has noted some predominance of RFLP pattern in East Asia. The RFLP patterns of tuberculosis strains collected at SNUH was studied and was compared with other strains from East Asia. Method : Fifty strains of M. tuberculosis were isolated from patients who visited 'or were admitted to the SNUH in 1998. Some isolates belonging to the Beijing family were also received. After the extraction of DNA from M. tuberculosis isolates, the chromosomal DNAs were digested with Pvu-II and analyzed by the Southern blot method with DNA probe to IS6110. Result : Six strains belonged to the Beijing family. The RFLP patterns of other 9 strains were similar to each other. No statistically significant endobronchial tuberculosis, presence of underlying disease. and the province of residence were found. Conclusion : Few groups of M. tuberculosis strains from SNUH showed similar RFLP patterns, but their clinical implications are not yet clear.

Over the last 3 years, the global food 3D printing market has grown at an average annual rate of 31.5% and has shown an industry size that reached about U$ 9.46 billion. Food 3D printing technology has the advantage of being utilizable in diverse ranges because it enables free design of existing foods so that foods can be produced according to individuals' tastes and purposes. Many countries around the world are producing food 3D printers to release trial products such as foods employing the advantages of food 3D printing. They are also attempting to apply food 3D printing in various fields such as combat rations, space rations, restaurants, liquid foods, foods for the elderly, diets for patients, and baby foods. Whereas the 3D printing market, which has a high growth potential and is expected to continue to expand in size, is highly likely to become a blue ocean, not only is food 3D printing technology small in South Korea, but also the overall ratio of 3D printing utilization and the scale of the relevant industry are small. This is attributable to the fact that South Korea has problems such as insufficient institutionalization compared to developed countries and delays in the development of standardized domestic materials. Therefore, this paper is intended to inform the necessity of food 3D printing and describe food 3D printing technology and food 3D materials in order to obtain the additional effect of vitalizing the South Korean food 3D printing market.

There has been increasing number of patients with asthma, rhinitis, and conjunctivitis due to the atmospheric pollution and global warming. In this study, we investigated daily observed number of pollens to establish a standardized method for the impact analysis of the climate changes on the number of daily pollens in Korea. Daily observed allergenic pollens of trees, weeds, and pine were analyzed during the period of 1998 to 2010 (except 2006) in Seoul, Busan, Daegu, Gwangju, Gangneung, and Jeju. They increased in large cities including Seoul during the last 12 years and the long-term trend may continue in the future. Daily concentration or amount of pollens was highly correlated with weather variables. Positive correlation was found between air temperature and the pollens although different relationships existed for different locations. Chill days were utilized to estimate the length of the flowering or pollen period. The pollen period of trees was shorter in the field when the winter temperature was low. This approach may be utilized to determine the quantitative change in length of the pollen season in the future.

According to the development of ubiquitous technologies, sensor networks is used in various area. In particular, medical field is one of the significant application areas using sensor networks, and recently it has come to be more important according to standardization of the body sensor networks technology. There are special characteristics of their own for medical sensor networks, which are different from the one of sensor networks for general application or environment. In this paper, we propose a hierarchical medical sensor networks structure considering own properties of medical applications, and also introduce transmission mechanism based on hierarchical structure. Our mechanism uses the priority and threshold value for medical sensor nodes considering patient's needs and health condition. Through this way Cluster head can transmit emergency data to the Base station rapidly. We also present the new key establishment mechanism based on key management mechanism which is proposed by L. Eschenauer and V. Gligor for our proposed structure and transmission mechanism. We use key provisioning for emergency nodes that have high priority based on patients' health condition. This mechanism guarantees the emergency nodes to establish the key and transmit the urgent message to the new cluster head more rapidly through preparing key establishment with key provisioning. We analyze the efficiency of our mechanism through comparing the amount of traffic and energy consumption with analysis and simulation with QualNet simulator. We also implemented our key management mechanism on TmoteSKY sensor board using TinyOS 2.0 and through this experiments we proved that the new mechanism could be actually utilized in network design.

The purpose of this study was to determine the relationships among the social support, depression, and health-related quality of life and the factors affecting the health-related quality of life in patients with coronary artery bypass graft (CABG). The subjects consisted of 134 patients who had received CABG from S general hospitals in Seoul, Korea, and the results were analyzed using the SPSS Win 21.0 program. The physical component summary (PCS) was significantly different depending on the age (F=4.616, p=.004), gender (t=3.657, p<.001), education (F=7.688, p=.001), current job (t=-4.363, p<.001), spouse (t=-3.065, p=.003), and underlying disease (F=3.078, p=.030) of the subjects. There were differences in the scores for the mental component summary (MCS) according to their gender (t=2.243, p=.027) and monthly income (F=2.821, p=.041). A significant negative correlation was found between social support and depression (r=-.415, p<.001). Social support had a statistically significant positive correlation with the MCS (r=.261, p=.002). Significant negative correlations were found between depression and the PCS (r=-.459, p<.001) and MCS (r=-.554, p<.001). The depression and underlying disease accounted for 36.7% of the variance in the PCS. The depression accounted for 34.1% of the variance in the MCS. Based on these results, nurses should develop nursing intervention programs for patients who have undergone CABG which take into consideration their depression.

Purpose: This study was performed to evaluate of practicum by using standardized patient(SP) for nursing assessment. Method: This study had 2 steps. The 1st-step was pre-intervention stage including selection of a learning title, formation of case scenario, training of SP and developing the evaluation tools for students' clinical competence to assessment, 6 categories 29 items. The 2nd-step consisted of intervention and evaluation stages. 34 nursing students divided 2 groups participated in assessing the SP. Evaluation of each group was performed by 2 nursing professors. All students recorded their feelings after assessing the SP. The SP also evaluated about nursing students' attitude toward the SP. Results: ICC(Interclass correlation coefficient) between 2 groups was over 0.7 all categories. Students' assessing score(range 0-1) was muscular-joint function status(0.41), nutritional status(0.39), history taking(0.38), IADL(0.18), ADL(0.15), and emotional status (0.07). The mean scores of the nursing students' attitude by SP was 4.03(range 1-6). Also most students showed positive reactions to the education using SP because they had the chance to experience what they could not practice in clinical setting. Conclusion: The evaluation tool revealed high reliability. Nursing students' clinical competence was below average. But they took a good attitude to SP. We recommended further research using SP with various disease.
