캥거루 케어의 특징을 반영하여 신생아의 감성에 긍정적인 영향을 미치는 스마트 감성 매트(SSM; Smart Sensibility Mat)를 개발, 제작하였다. 청감 자극의 경우 사전에 녹음된 어머니의 심장박동소리와 목소리를 30dB로 제공할 수 있는 블루투스 스피커를 매트에 삽입하였다. 촉감 자극의 경우 $32^{\circ}C$의 일정한 온도를 제공하기 위해 실리콘 소재의 온수 튜브를 매트의 표면에 삽입하고 자동온도조절장치와 연결하였다. 매트의 전체에 균일한 온도 제공을 위해 열전도성 실을 삽입한 직물을 매트 표면에 부착하였다. 면 패드로 매트를 감싼 후 피부 접촉과 비슷한 촉감 자극을 주기 위해 폴리우레탄 폼을 매트 표면에 접착하였다. SSM이 신생아의 감성에 미치는 효과를 보기 위해 생후 2주 이내의 건강한 신생아 10명을 대상으로 일반 매트(GM; General Mat) 및 SSM에 있을 때 생리신호인 심박수, 호흡수와 체온을 10분 간격으로 2회씩 측정하였다. 이를 3일에 걸쳐 1일 1회씩 측정한 후 대응표본 t검정을 실시하였다. 그 결과, GM에 있을 때 보다 SSM에 있을 때 심박수(t=8.131, p<.001)와 호흡수(t=7.227, p<.001)가 정상범위 안에서 유의적으로 감소하였다. 이는 SSM의 감각 자극이 신생아의 심리적 안정에 긍정적인 영향을 미쳐 GM보다 빠른 시간 내에 심리적 안정을 주는데 기여한 것으로 볼 수 있다.

Human papillomavirus (HPV) types 16 and 18 are the major causes of cervical lesions and are associated with 71% of cervical cancer cases globally. However, public health infrastructures to support cervical cancer screening may be unavailable to women in low-resource areas. Therefore, sensitive, convenient, and cost-efficient diagnostic methods are required for the detection of HPV16/18. Here, we designed two novel methods, real-time ERA and ERA-LFD, based on enzymatic recombinase amplification (ERA) for quick point-of-care identification of the HPV E6/E7 genes. The entire detection process could be completed within 25 min at a constant low temperature (35-43℃), and the results of the combined methods could be present as the amplification curves or the bands presented on dipsticks and directly interpreted with the naked eye. The ERA assays evaluated using standard plasmids carrying the E6/E7 genes and clinical samples exhibited excellent specificity, as no cross-reaction with other common HPV types was observed. The detection limits of our ERA assays were 10⁰ and 10¹ copies/µl for HPV16 and 18 respectively, which were comparable to those of the real-time PCR assay. Assessment of the clinical performance of the ERA assays using 114 cervical tissue samples demonstrated that they are highly consistent with real-time PCR, the gold standard for HPV detection. This study demonstrated that ERA-based assays possess excellent sensitivity, specificity, and repeatability for HPV16 and HPV18 detection with great potential to become robust diagnostic tools in local hospitals and field studies.

A permanent deformation model was developed in this study based on the shear properties of asphalt mixtures such as cohesion and friction angle. Triaxial compressive strength (TCS) and repeated load permanent deformation (RLPD) tests on the three types of asphalt mixtures are performed at various loading and temperature conditions to correlate shear properties of asphalt mixtures to rutting performance. It is observed from the tests results that the ratio of shear stress to strength accurately identifies the mixture rutting performance. It could take care of not only mixture types but also load and temperature conditions dependences. Three different versions of the permanent deformation model based on different input levels are proposed and verified using the tests data. The proposed model based on the ratio of shear stress to strength can successfully predict the permanent deformation of various asphalt mixtures all the way up to the 10% of permanent strain including all three stages of permanent deformation in a wide range of loading and temperature conditions without changing model coefficients.

Turbulent temperature field in a channel with wall injection has been investigated using dynamic mixed model(DMM). This flow is pertinent to internal flows inside the hybrid rocket motors. In general, the results obtained with DMM are in better agreement with DNS results compared to those of dynamic Smagorinsky model(DSM). Such favorable features of DMM are attributed to the fact that it explicitly calculates the modified Leonard stress term which takes care of the local interaction between resolved and SGS stresses and only models the remaining cross and SGS Reynolds stress terms.

Reinforced concrete beams or slabs are often strengthened or repaired using polymer modified cement concrete Stresses can develop in the structure by ambient temperature changes because thermal coefficients of the repair material and the existing concrete are typically different. Especially, shear stress often causes debonding of the interface. In this study, a rational procedure was developed where anchors can be designed in strengthened or repaired concrete members to prevent debonding at the interface. The current design procedure considers thicknesses and elastic moduli of the repair material and existing concrete, ambient temperature change, length, and beam-vs.-slab action. The procedure is also applicable to stresses developed by differential drying shrinkage.

Purpose: The purpose of this study was to develop sleeve-type restraints and to compare the sleeve-type and conventional wrist restraints. Methods: Forty four pairs of intensive care unit (ICU) patients and their families participated in the experiment. The nurses applied sleeve-type restraints to the patients in the experimental group, and wrist restraints to the control group. The trained research assistant measured ROMs, skin temperature, edema, and skin lesions of both upper extremities (UEs) before, 24, 48, and 72 hours after the restraints applied. The emotional response of family was measured 72 hours after the restraints applied. Thirty one ICU nurses evaluated the efficiency of both types of restraints. Results: Compared to the control group, changes of ROMs, edema, and skin abrasions on both U/Es of the experimental group indicated a significant difference in physical side effects. The emotional response scores of the experimental group were significantly lower than those of the control group. The mean efficiency scores for the sleeve-type restraints were significantly higher than those for the wrist restraints. Conclusion: The results indicate that the sleeve-type restraints are better than wrist restraints with respect to physical side effects, emotional responses of family members, and application efficiency.

The purpose of this research was to identify nursing interventions performed by hospital nurses in Korea. The sample consisted of 311 nurses working in three hospitals. The Nursing Interventions Use Questionnaire developed by the Iowa Intervention Project team was used for data collection. The instrument was translated to Korean using the method of back-translation. Eighteen interventions were performed at least daily. Interventions in the Physiological : Basic domain were most frequently used at least daily. No interventions in the Family and Behavioral domains were used by nurses at least once a day. The most frequently used interventions was Documentation, followed by the interventions Medication : Parenteral, Intravenous(IV) Insertion, Temperature Control, and Shift Report. The intervention performed least often was Reproductive Technology Management. Nurses working in intensive care units on the whole performed interventions most often, while nurses working in obstetric, gynecological, and pediatric units performed them least often. The nurses working in intensive care unit, medical and surgical care units performed the interventions in the Physiological : Basic domain more often than the nurses working in obstetric, gynecological, and pediatric units. The nurses working in obstetric, gynecological, and pediatric units used the interventions in the Family domain more often than the nurses working in the other three units. This study contributes to the documentation of nursrs' work in Korea. Further study will be needed to validate nursing activities of each NIC intervention.

최근, 유비쿼터스 관련 산업이 비약적으로 발전하고 있으며, 특정 구역을 대상으로 유비쿼터스 환경을 구축하는 u-Zone의 개발이 추진되고 있다. 특히 헬스케어 시스템의 관점에서 보면, u-Zone을 활용하여 정신질환자나 거동이 불편한 환자를 관리하기 위한 비용과 노력을 감축시킬 수 있다. 하지만 아직 헬스케어 시스템은 특정 개인을 대상으로 하거나 병원 내부 시스템을 확장하는 수준에 그치고 있다. 정신질환자 중에는 알코올, 마약 등의 약물에 중독된 환자의 비율이 높지만, 일상적인 데이터의 수집이 어려워 체계적인 관리나 정확한 진단이 어렵다. 따라서 본 논문에서는 u-Zone 내에서 중독환자에게 생체신호 측정 센서를 통해 지속적인 정보를 수집하고, 모니터링할 수 있는 시스템을 제안하였다. 맥박, 체온, 가속도 센서를 이용하여 환자 상태정보를 수집하고, 이를 기반으로 감정 상태를 판별하여 정확한 진단의 근거가 될 수 있도록 한다.
