A 21-year-old male visited our emergency room. He could not remember the mechanism of injury. He was found beside a motorcycle. Initial vital sign was stable. Observation and conservative treatment were planned at the intensive care unit (ICU). On the third day at ICU, he complained sudden flank pain. It was colicky and hard to control. Without the pain, he had no specific symptom, sign, or laboratory findings. On computed tomography, renal pelvis was filled with hematoma which induced hydronephrosis. Double-J catheter and percutaneous nephrostomy was implemented by an intervention radiologist. Hematome in the renal pelvis was aspirated during the procedure. Symptom of the patient was subsided after the procedure. He was discharged without specific complications.

Exchanging personal health information(PHI) is an essential process of healthcare services using information and communication technology. But the process have the inherent risk of information disclosure, so the PHI should be protected to ensure the reliability of healthcare services. In this paper, we designed encryption module for wearable personal health devices(PHD). A main goal is to guarantee that the real-time encoded and transmitted PHI cannot be allowed to be read, revised and utilized without user's permission. To achieve this, encryption algorithms as DES and 3DES were implemented in modules operating in Telos Rev B(16bit RISC, 8Mhz). And the experiments were performed in order to evaluate the performance of encryption and decryption using vital-sign measured by PHD. As experimental results, an block encryption was measured the followings: DES required 1.802 ms and 3DES required 6.683 ms. Also, we verified the interoperability among heterogeneous devices by testing that the encrypted data in Telos could be decoded in other machines without errors. In conclusion, the encryption module is the method that a PHD user is given the powerful right to decide for authority of accessing his PHI, so it is expected to contribute the trusted healthcare service distribution.

Objectives The aim of this clinical study was to find out the changes of vital sign, body composition, skin status before and after combined spa-exercise therapy in participants of middle-aged women. Methods In this study 24 participants of middle-aged women went through 12 weeks of combined spa-exercise therapy. Each week vital sign, body composition, skin status were measured before exercise, which consisted of warming-up, whole body exercise and final exercises bathing in spa ($32{\sim}36^{\circ}C$). Results 1. The average of systolic blood pressure significantly decreased from $126.38{\pm}19.33mmHg$ to $120.46{\pm}11.18mmHg$ after 11 weeks of spa-exercise therapy (p<0.05). 2. The average of moisture of skin significantly increased from $36.83{\pm}3.18$ to $44.21{\pm}7.43$ after 11 weeks of spa-exercise therapy (p<0.05). 3. The average of elasticity of skin significantly increased from $59.75{\pm}3.50$ to $62.63{\pm}2.29$ after 11 weeks of spa-exercise therapy (p<0.05). 4. The average of diastolic blood pressure, pulse, et cetera. didn't significantly change after spa-exercise therapy. Conclusions The results showed that 12 weeks of spa-exercise therapy had significant effect on reducing systolic blood pressure, increasing moisture, elasticity of skin in participants of middle-aged women, which means spa-exercise therapy may be used as a treatment on high blood pressure and cutaneous diseases. Further studies are anticipated to find out other various effects of spa-exercise therapy.

Objectives The purpose of this study is to evaluate the safety of Gunghatang tablet in healthy male volunteers. Methods Single center pharmacokinetics study was carried out in healthy male volunteers. Through the laboratory test, vital sign and adverse event data, safety evaluation was conducted. Total 15 of 16 subjects who met the inclusion criteria were enrolled and three subjects were allocated to waiting group. 12 subjects were allocated by serial number according to registration order. Subjects took the maximum daily dose of the tablet on the second day of hospitalization. For the evaluation of safety, blood samples were collected and vital sign were checked 4 times (screening, before administration, after administration and follow up period) during the trial. All adverse events were recorded and summarized as frequency and percentage. All continuous data were summarized as mean and standard deviation. For comparison of variables between before administration and after administration, data were analyzed by paired T-test or Wilcoxon signed rank test (p<0.05). Results As a result of all data related to vital sign and laboratory test in both group, there were no significant differences associated with the clinical trial drug between pre and post administration. And there was no adverse event associated with the clinical trial drug. Conclusions Gunghatang tablet were found to be safe for healthy male volunteers.

Purpose: This study aimed to confirm the effect of routine suctioning at a nursery for healthy newborns who have undergone immediate oronasopharyngeal bulb suctioning after birth in a delivery room through the observation of their oxygen saturation level, heart rate, respiration rate, the vomiting sign, and the number of instances of vomiting. Methods: Data were collected for 62 days from March 15 to May 15, 2009 at the nursery of a hospital located in Seoul. One hundred forty newborns were assigned to one of three groups: a no suction group, an oropharyngeal suction group, or a orogastric suction group. Collected data were analyzed with the SPSS WIN 15.0 program using ANOVA, cross tabulations and an independent 2-sample t-test. Results: Routine suctioning to healthy newborns resulted in decreasing oxygen saturation levels and increasing the heart and respiration rate regardless of the kind of suctioning. Stabilization of the oxygen saturation level and vital signs was also observed without suctioning. Conclusion: To prevent healthy newborns from the side effect of suctioning, selective suctioning is recommended.

Recently, owing to global warming, average summer temperatures are increasing and the number of hot days is increasing is increasing, which leads to an increase in heat stroke. In particular, outdoor workers directly exposed to the heat are at higher risk of heat stroke; therefore, preventing heat-related illnesses and managing safety have become important. Although various wearable devices have been developed to prevent heat stroke for outdoor workers, applying various sensors to the safety helmets that workers must wear is an excellent alternative. In this study, we developed a smart helmet that measures various vital signs of the wearer such as body temperature, heart rate, and sweat rate; external environmental signals such as temperature and humidity; and movement signals of the wearer such as roll and pitch angles. The smart helmet can acquire the various data by connecting with a smartphone application. Environmental data can check the status of heat wave advisory, and the individual vital signs can monitor the health of workers. In addition, we developed an algorithm that classifies the risk of heat-related illness as normal and abnormal by inputting a set of vital signs of the wearer using a support vector machine technique, which is a machine learning technique that allows for rapid binary classification with high reliability. Furthermore, the classified results suggest that the safety manager can supervise the prevention of heat stroke by receiving feedback from the control system.
