In this paper, we propose the biometrics system using hand vein pattern. This system is for management about person's entrance/exit in vessel USN. we select the biometrics method using hand vein pattern as adoptable method to vessel USN environment. Our experimental results show that preprocessing using two dimensional gabor filter achieves performance improvements over high pass filtering. Also, we compared our method with measured FAR(False Acceptance Rate) and FRR(False Rejection Rate) using pattern matching, the results show low error rate over high pass filtering. As a result, we verify the adoptability of biometrics system using hand vein pattern in management of person's entrance/exit in vessel.

This study was attempted to identify the perception and experience of hospital nurses on medication errors of high-risk intravenous drugs, and to identify the causes of medication errors and ways to improve them. The subjects of the study were nurses with work experience related to high-risk intravenous administration working at a university hospital located in D City, and data were collected between May 16 ~ 30, 2021. As a result of the study, six key factors were identified as the key factors in the safety of high-risk intravenous injections: the lack of a protocol for the administration of major drugs in each ward, the lack of training in the operation of the injection machine, the lack of standardized procedures for administering high-risk intravenous injections, the lack of individualized medication training for nurses, the lack or lack of the hospital's own drug list, and the lack of identification of drugs packaged in similar containers. At the nursing practice level, it is proposed to apply a high-risk intravenous medication safety program and conduct a future study to identify safety outcome indicators.

In this paper, we analyze the characteristics and ATM applications for fingerprint, iris, vein recognition technology that can be applied to the ATM to reinforce security. Describe the important requirements to be considered when introducing a biometric authentication in the ATM, and were compared to each biometric authentication scheme based on these requirements. Fingerprint authentication has limitations in accuracy, iris recognition is a big weakness in user convenience, whereas vein recognition has the advantage of being hygienic, yet excellent accuracy and secrecy. Vein authentication approach is expected to be expanded to apply to ATM due to the many advantages.

Purpose: The purpose of the study was to investigate how much understand about artificial hydration in patients with terminal cancer, according to the subject groups, including patients, families, and general public. Methods: Data were collected from June 2007 to December 2007 and the participants included 22 hospitalized patients in the hospice unit of S Hospital, 100 families, and 101 participants who participated in a hospice education program for the general public. The questionnaire was developed through literature review, interview with patients' families, and expertise consultation. Data were analyzed using descriptive statistics with an SAS program. Results: Understanding of artificial hydration among patients, families and general public was examined from three perspectives. From an ethical perspective, 'if you receive artificial hydration, you can live longer', 45.5%, 63%, and 52.4% of the above three groups, respectively, answered "yes". From an emotional perspective, 'artificial hydration must be provided', 81.8%, 70% and 58.4%, respectively, agreed. From a cultural perspective, 'if artificial hydration is not provided for the patient, the families will feel painful', 95.5%, 83%, and 88.2%, respectively, answered "yes". Conclusion: This study found the differences in understanding of artificial hydration among patients, families and general public, and also found that less than 50 percent of the participants understood artificial hydration appropriately. We suggest, therefore, that patients' understanding about artificial hydration should be determined in the clinical setting and then followed by individualized education according to given medical situations.

Persistent left superior vena cava (PLSVC) is a rare congenital, thoracic, and vascular anomaly. Although PLSVCs generally do not have a hemodynamic effect, several types of PLSVC and some cardiac anomalies may manifest with clinical symptoms. The presence of PLSVC can render catheterization via left subclavian access difficult when placing a pacemaker or central venous catheter. As such, recognizing a PLSVC that is typically incidentally discovered can prevent complications such as vascular injury. Differentiating vessels found in a similar location as PLSVC is necessary when performing thoracic vascular procedures. This pictorial essay explains the multi-detector CT findings of a PLSVC, and provides a summary of other blood vessels that require differentiation during thoracic vascular procedures.

Separable Gabor 필터는 기존의 2D Gabor 필터를 x축 성분과 y축 성분만을 지니는 두 개의 1D 필터로 나누어 각각 적용하는 방법으로 속도 향상을 가져왔으며, 지문인식 등에서 사용되어왔다. 하지만 정맥과 같은 경우에는 지문의 융선들 보다 더 굵기 때문에 필터의 크기 또한 매우 커진다. 따라서 Separable Gabor 필터의 경우도 지문에서만큼의 빠른 속도를 내지는 못한다. 본 논문에서는 Separable Gabor 필터 보다 더욱 고속의 연산이 가능한 Separable Symmetric Gabor 필터를 제안하였다. 이 필터는 사선 방향으로의 특징을 강조함에 있어 동시에 대칭이 되는 각도의 특성까지 강조하고, 회선 과정에서 필터의 방향 값을 고려하지 않기 때문에 인덱스 계산이 매우 단순해져 기존의 Separable Gabor 필터보다 처리 속도를 향상시킬 수 있다.

Phlebectasia is an abnormal dilatation of an isolated vein and a rare venous anomaly and is usually asymptomatic. Clinically internal jugular phlebectasia is a self limited benign condition and usually no treatment is required after initial diagnosis. So suspection of this disease and appropriate diagnostic approaches are essential to avoid unnecessary surgical intervention. We present three cases of internal jugular phlebectasia of which diagnosis was made by neck sonography and CT.

Biometrics consist of technologies that support automatic identification or verification of identity based on behavioral or physical traits. Biometrics can authenticate identities since they measure unique individual characteristics including fingerprints, hand geometry, iris, hand vascular patterns and facial characteristics. we review the state of the hand vascular patterns identification technology and compare other competitive authentication technologies such as cryptography, electronic signature and PKI.

Biometrics are best defined as measurable physiological and behavioral characteristics that can be utilized to verify the identity of an individual. Biometric technologies will continue to improve, becoming even more accurate and reliable as technology evolves. In this paper, we review the state of the hand vascular patterns identification technology and analyse the opportunities and threats of the technology in the markets.
