A fuzzy identity based signature (FIBS) scheme allows a signer with identity ${\omega}$ to generate a signature which could be verified under identity ${\omega}^{\prime}$ if and only if ${\omega}$ and ${\omega}^{\prime}$ are within a certain distance of each other as judged by some metric. In this paper, we propose an efficient FIBS scheme from lattice assumption, which can resist quantum-computer attacks. Without using the Bonsai Tree technique, we utilize the lattice basis delegation technique to generate the private key, which has the advantage of keeping the lattice dimension invariant. We also prove that our proposed scheme is existentially unforgeable under an adaptive chosen message and identity attack in the random oracle model. Compared with existing scheme, our proposed scheme is much more efficient, especially in terms of communication overhead. Since our FIBS scheme possesses similar error-tolerance property, it can be well applied in post-quantum communication biometric authentication environments, where biometric identifiers such as fingerprints, voice, iris and gait are used in human identification.

Purpose: Compared to cities, rural areas are in a medical blind spot and face difficulties in accessing medical services due to inconvenient transportation facilities, lack of medical facilities, and the heavy burden of medical expenses. This study was carried out to identify the problems relating to the musculoskeletal system of the elderly in rural and fishing villages, which are medically vulnerable areas, and sought to present a regionally differentiated healthcare model. Methods: The study was conducted in 80 elderly people in two rural villages and two fishing villages after seeking inputs regarding medically vulnerable groups in the Gyeongnam Province. Postural balance and muscle flexibility were assessed and postural evaluation was conducted to identify musculoskeletal problems and gait stability. Strength and range of motion for each body segment were assessed for evaluating functional motion. Results: The elderly in both rural areas showed forward head posture characteristics. The strength level of the elderly in both rural areas was higher than the average, but their flexibility and balance ability were lower than the average. Conclusion: The musculoskeletal problems of the elderly in rural and fishing villages in this study did not show regional characteristics according to the area of residence. However, overall flexibility and balance ability appeared to be reduced. Therefore, a new management model connecting the region and the university is necessary in preparation for the coming era of community care.

Objective: This study explored the reuse of data captured into an electronic nursing record system using the International Classification for Nursing Practice to support nursing research of inpatient's falls. Methods: Risk factors relevant to inpatients falls ;n an acute setting were identified from the literature review. Four risk assessment tools and two risk identification studies were selected. To examine the availability of coded data in an electronic nursing record system for the identified fall fisk factors, we reviewed 11.319 hospital-day records of 118 patients who were reported by the self-report system. Results: We identified 24 fall risk factors of five categories from the literature review, which were used to identify the standard nursing statements addressing fall risks. One hundred thirty five nursing statements were searched from the hospital's nursing data dictionary of statements and were matched with 14 fall fisk factors. Using the 135 statements. we found that mental status, catheter of drip in situ, abnormal gait, insomnia, surgical procedure. and dizziness/vertigo appeared frequently in the nursing records of inpatients with fall s. Also we found 6 risk factors more through the record review. Conclusion: The electronic records would be a good research source for inpatients' falls. Specifically international classification for nursing practice based nursing record system has the potential for promoting clinical researches.

Objectives Edema occurs in various disorders, such as heart failure, nephrotic syndrome, renal failure, liver cirrhosis, and cancer. The excessive accumulation of interstitial fluid in limb tissue will often manifest with ankle and knee swelling and lowers patient's quality of life. But the conventional treatment includes restricting dietary sodium and using diuretics. The purpose of this study is about significant improvement of a patient with edema who had suffered from dependent gait accompanied by mild pain, after treatment by herbal medicine based on SCM(Sasang constitutional medicine). Methods The pattern identification of the patient was diagnosed with a superficial disease of Taeeumin. So after the admission, Gunyuljejo-tang was used, almost two times per day during 2 weeks. Also, we applied acupuncture routinely every day and western medicine as needed. We measured the circumferences of Lt. thigh and followed up the bioelectrical impedance analysis and checked the appearance of lower limb. Results and Conclusions The therapy was effective, and the circumferences, which was 59.69cm at onset time, decreased to 52.07cm almost same to the healthy side of her thigh. There was no more edematous sign on the body, either. This case showed that management of Taeeumin's healthy energy(呼散之氣, the energy of exhalation) could be effective in treating edema.
