최근 센서 기술의 발달로 인하여 체내삽입장치를 부착한 환자가 언제, 어디서나 의료 서비스를 받을 수 있는 환경으로 변화하고 있다. 그러나, 체내삽입장치를 부착한 환자의 생체정보가 병원관계자(의사, 간호사, 약사 등)에게 전달할 때, 환자의 정보가 제 3자에게 쉽게 노출되어 악용될 수 있는 문제점이 발생되고 있다. 본 논문에서는 제3자가 환자로 위장하여 병원관계자로부터 환자 정보를 쉽게 획득할 수 없도록 유헬스케어 서비스 센터로부터 환자의 위임장을 병원관계자가 전달받는 위임장 기반의 서명 인증 프로토콜을 제안한다. 제안 프로토콜은 환자의 민감한 정보를 제 3자에게 노출시키지 않도록 환자의 민감한 정보를 유헬스케어 서비스 센터와 환자가 생성한 랜덤수로 해쉬한 서명키로 환자의 민감한 정보를 암호화한다. 또한 제 3자로부터 환자 정보가 불법적으로 악용되는 것을 예방하기 위해서 환자와 병원관계자 사이의 동기화를 유지함으로써 환자의 생체 정보 유출을 예방할 수 있다.

Purpose: The purpose of this study was to identify the characteristics of and risk factors for medical-device-related pressure ulcer (MDRPU) development in intensive care units. Methods: A prospective cohort study design was used, and the participants were 253 adult patients who had stayed in medical and surgical intensive care units. Data were collected regarding the application of medical devices and MDRPU-related characteristics over a period of six months from June to November, 2017. Data were analyzed using independent t-test, ${\chi}^2-test$, Fisher's exact test, and binary logistic regression analysis with the SPSS 21.0 program. Results: Among the 253 participants, MDRPUs occurred in 51 (19.8%) participants. The results of the logistic regression analysis showed that the risk factors for MDRPUs were the use of endotracheal tubes (OR=5.79, 95% CI: 1.66~20.20), having had surgery (OR=2.95, 95% CI: 1.11~7.77), being in a semi-coma/coma (OR=5.79, 95% CI: 1.04~32.05), and sedation (OR=5.54, 95% CI: 1.39~22.19). Conclusion: On the basis of the study results, it is effectively facilitated by nurses when they care for patients with MDRPUs in intensive care units and the results are expected to be of help in preventive education for MDRPU development as well as preparing the base data for intervention studies.

The study aimed to understand the knee condition of patients with knee joint pain who visited an Korean Medicine hospital by performing musculoskeletal ultrasound. From July 1, 2021 to October 31, 2021, information on the gender, age, diagnosis, and ultrasound findings of knee joint pain patients were retrospectively collected. To examine the condition of the knee joint, images were taken in a total of three postures. All images were analyzed by an examiner. 7 cases of osteoarthritis, 1 case of medial collateral ligament rupture, and 1 case of quadriceps tendon calcification were collected. It was able to check the condition of articular cartilage, lipoma arborescens, and the formation of osteophytes through musculoskeletal ultrasound. The implementation of musculoskeletal ultrasound can enable Korean medicine doctors to give more active treatment for patients through accurate and scientific diagnosis. Based on more evidence, it is thought that the use of medical devices by Korean medicine doctors will need to be made in the future.

Background: The purpose of this study was to assess the effect of our new video-assisted asthma education program on patients' knowledge regarding asthma and asthma control. Methods: Adult asthmatics who were diagnosed by primary care physicians and followed for at least 1 year were educated via smart devices and pamphlets. The education sessions were carried out three times at 2-week intervals. Each education period lasted at most 5 minutes. The effectiveness was then evaluated using questionnaires and an asthma control test (ACT). Results: The study enrolled 144 patients (mean age, $56.7{\pm}16.7years$). Half of the patients had not been taught how to use their inhalers. After participating in the education program, the participants' understanding of asthma improved significantly across all six items of a questionnaire assessing their general knowledge of asthma. The proportion of patients who made errors while manipulating their inhalers was reduced to less than 10%. The ACT score increased from $16.6{\pm}4.6$ to $20.0{\pm}3.9$ (p<0.001). The number of asthmatics whose ACT score was at least 20 increased from 45 (33.3%) to 93 (65.3%) (p<0.001). The magnitude of improvement in the ACT score did not differ between patients who received an education session at least three times within 1 year and those who had not. The majority of patients agreed to the need for an education program (95.8%) and showed a willingness to pay an additional cost for the education (81.9%). Conclusion: This study indicated that our newly developed education program would become an effective component of asthma management in primary care clinics.

In this study, we attempted to investigate the needs and problems of the terminal cancer patients and their family caregivers to provide them with nursing information to improve their quality of life and prepare for a peaceful death. Data was collected from August 1, 1995 to July 31, 1996 at the internal medicine unit of S hospital in Seoul area with the two groups of participants who were family members of terminal cancer patients seventy four of them were in-patients and 34 were out-patients who were discharged from the same hospital for home care. The research tool used in this study has been developed by selecting the questionnaires from various references, modifying them for our purpose and refining them based on the results of preliminary study. While general background information about the patients was obtained by reviewing their medical records, all other information was collected by interviewing the primary family caregivers of the patients using the questionnaire. The data collected were analyzed with the SPSS PC/sup +/ program. The results of this study are summarized as follows ; 1) Most frequently complained symptoms of the terminal cancer patients were in the order of pain(87%), weakness(86.1%), anorexia(83.3%) and fatigue (80.6%). 2) Main therapies for the terminal cancer patients were pain control (58.3%), hyperalimentation(47.2%) and antibiotics(21.3%). 3) Special medical devices that terminal cancer patients used most were oxygen device (11.1%), and feeding tube(5.6%). Other devices were used by less than 5% of the patients. 4) The mobility of 70.4% of the patients was worse than ECOG 3 level, they had to stay in bed more than 50% of a day. 5) Patients wanted their medical staffs to help relieve pain(45.4%), various physical symptoms(29.6%), and problems associated with their emotion(11.1%). 6) 16.7% of the family caregivers hoped for full recovery of the patients, refusing to admit the status of the patients. Also, 37% wished for the extension of the patient's life at least for 6 months. 7) Only 38.9% of the family members was preparing for the patient's funeral. 8) 45.4% of family caregivers prefer hospital as the place for the patient's death, 39.8% their own home, and 14.8% undetermined. 9) Caregivers of the patients were mostly close family members, i.e., spouse(62%), and sons and daughters or daughter-in-laws(21.3%). 10) 43.5% of the family caregivers were aware of hospice care. 46.8% of them learned about the hospice care from the mass media, 27.7% from health professionals, and the rest from books and other sources. 11) Caregivers were asked about the most difficult problems they encounter in home care, 41 of them pointed out the lack of health professionals they can contact, counsel and get help from in case of emergency, 17 identified the difficulty of finding appropriate transportation to hospital, and 13 stated the difficulty of admission in hospital as needed. 12) 93.6% of family caregivers demanded 24-hour hot line, 80% the visiting nurses and doctors, and 69.4% the volunteer's help. The above results indicate that terminal patients and their family caregivers demand help from qualified health professionals whenever necessary. Hospice care system led by well-trained medical and nursing staffs is one of the viable answers for such demands.

A cryotherapy system using the low temperature air was developed. The developed cryotherapy system had superior low temperature characteristics and many safety devices. For a clinical evaluation, skin and intra-articular temperatures of the knee joint were measured during and after the cryotherapy. After 5-minute therapy, skin and intra-articular temperature decreased by $23.3{\pm}4.7(^{\circ}C)$ and $4.1{\pm}1.0(^{\circ}C)$ respectively. A 5-minute cryotherapy therapy is good enough to maintain low intra-articular temperatures or 2-3 hours.

Purpose: The purpose of this study was to evaluate nursing protocols for superficial cryotherapy in different medical institutions. Methods: The study was conducted with a cross-sectional descriptive design. The medical institutions including general hospitals, hospitals, and geriatric hospitals were randomly selected. A total of 435 nurses from 126 institutions completed a questionnaire. Data were collected from December 2014 to June 2015. Results: Forty-two institutions (39.5%) had nursing protocol for cryotherapy. The nurses reported that durations of cold application were 2 minutes to 5 hours. Frequently used cold therapy devices in order of frequency were frozen gel packs, ice packs, and frozen IV fluid bags. There were variances in the duration of cold application according to the types of institution ($x^2=7.78$, p=.020) and nursing units ($x^2=26.42$, p<.001). In addition, intervals of cold application were different according to the nursing units (x=12.23, p=.032). There were differences in cold application instruments by regional groups (x=70.38, p<.001). Most of the nurses (95.6%) responded that national nursing protocol for superficial cryotherapy were needed. Conclusion: There were difficulties in providing consistent nursing interventions because of the practical differences and absence of evidence-based guidelines for cryotherapy. The researchers recommend that basic studies with various instruments be conducted and proper nursing protocols be developed for cryotherapy.

Zygomatic fractures are the second most common facial bone fractures encountered and treated by plastic surgeons. Stable fixation of fractured fragments after adequate exposure is critical for ensuring three-dimensional anatomic reduction. Between January 2008 and December 2010, 17 patients with zygomatic fractures were admitted to our hospital; there were 15 male and 2 female patients. The average age of the patients was 41 years (range, 19 to 75 years). We exposed the inferior orbital rim and zygomatic complex through a lateral brow, intraoral, and subciliary incisions, which allowed for visualization of the bone, and then the fractured parts were corrected using the Carroll-Girard T-bar screw. Postoperative complications such as malar asymmetry, diplopia, enophthalmos, and postoperative infection were not observed. Lower eyelid retraction and temporary ectropion occurred in 1 of the 17 patients. Functional and cosmetic results were excellent in nearly all of the cases. In this report, we describe using the Carroll-Girard T-bar screw for the reduction of zygomatic fractures. Because this instrument is easy to use and can rotate to any direction and vector, it can be used to correct displaced zygomatic bone more accurately and safely than other devices, without leaving facial scars.
