A pillow was fabricated through CAE(Computer Aided Engineering) and 3D printing, which can adjust automatically the height of the pillow when lying sideways and backwards according to the sleeping posture. The target height difference of the pillow was about 1.0 cm ~ 1.5 cm when the head weight difference was about 1.2 kg. Instead of using a complex mechanical device, it was based on an arch structure made of TPU. From the simulation, the optimum model was designed through series combination and the results were compared with the experimental ones. The final product had a height difference of about 2 cm according to the lying posture.

This study identified the complaint ratio of musculoskeletal symptom by 119 EMTs and investigated the work risk extent through ergonomics evaluation about the patient transport works, which cause work-related musculoskeletal disorders (WMSDs) to 119 EMTs. For this, the complaint ratio of musculoskeletal symptom utilized questionnaire tool based on KOSHA Code H-30-2008 and the risk extent about the patient transport work evaluated by using ergonomics evaluation tools such as OWAS, RULA and REBA. According to the study result, 60.9% of 119 EMTs experienced musculoskeletal symptom. Among them, the symptom on back was the most common (36.1%). The work, which mostly causes WMSDs, has been found as patient transport work (48.4%). Among the patient transport motion, loading/unloading of ambulance cot to/from ambulance and the lifting of patient by stretcher were OWAS risk-level 3 and RULA/REBA risk-level 3 to 4. Among the patient transport environment, carrying patient on stairway using emergency mini-stretcher, moving patient in vehicle using spine board and piggy-back carrying or cradle carrying patient on stairway or slope way were OWAS, RULA, REBA risk level 3 to 4. It is suggested that immediate improvement in work postures for these works should contribute to prevention against WMSDs to 119 EMTs.

편마비 환자의 물리치료는 장애 결과를 완화시키는 것에 초점을 두고 있다. 본 연구는 신경생리학적 개념을 기초로 한 중재 접근 방법 중 편마비 환자에게 신경 발달 치료와 신경근 균형 접근 기법의 중재 효과를 비교 하였다. 연구 대상은 서울특별시와 전라북도에 소재한 종합병원 및 정형외과 의원에 입원 및 통원하고 있는 47-71세의 연령 범위에 있는 편마비 환자 30명 이다. 중재 집단의 기능적 능력 향상을 평가하기 위해 편마비 환자를 위한 운동 평가 척도와 수정된 바델 척도를 평가도구로 사용하였다. 편마비 환자의 기능적 능력 향성을 평가도구에 의해 측정된 결과를 분석한 바 운동평가 척도 항목중 바로누운 자세에서 옆으로 눕기와 앉아서 균형 취하기 영역에서, 수정된 바델 척도 항목 중 식사하기 영역에서 통계적으로 유의한 차이를 보였다(P<.05). 편마비 환자의 손상 부위, 손상 형태, 마비 부위 등의 손상의 본질에 따른 대상의 선정과 운동 조절 형태에 관한 지식 그리고 신경학적 결함 정도를 심도있게 다루어 기능적 능력 향상의 임상적 효과를 검증하는 것이 중요하다.

한 국가의 국가경쟁력이 커지기 위해서는 여러 산업에 국제경쟁력이 있어야 한다. 특히 에너지 산업과 같이 전방효과가 큰 산업은 어떤 산업 보다도 경쟁력을 키워나가야 하는 산업이다. 본 논문에서는 국제경쟁력에 대한 개념 정리를 통해 규제완화를 포함한 정부의 역할이 에너지 산업의 국제경쟁력에 어떤 영향을 미치는가를 살펴보고 정부가 1994년에 발표한 규제완화조치가 에너지 산업의 국제경쟁력을 강화시키는데 충분한 조치인가를 석유산업을 중심으로 평가한 후 정부가 취해야 할 자세와 결정, 실천사항을 제언하였다. 한국의 국제경쟁력 모델을 이용한 분석에 의하면 한국의 에너지 산업은 부존자원과 경영환경면에서 열악한 모습을 보이는 반면, 근로자와 기업가면에서 경쟁력을 창출할 수 있는 요소를 간직하고 있다. 그러나 규제완화와 관련된 정부, 즉 정치가와 행정관료면에 있어서는 현 정부가 외형적으로 제시하는 규제완화조치에 대해서 큰 기대를 걸게 해 주지만 그 실천에 있어서는 기대가 큰 만큼 실망도 함께 주고 있다. 기업이 이윤극대화라는 목표를 달성하기 위해서 생산, 판매 등의 기업활동에 경영개념을 도입해야 하듯이, 국가 역시 국제경쟁력 강화라는 목표를 달성하기 위해서는 "규제완화조치"라는 정부활동에 사전계획, 현장집행, 사후평가로 이어지는 경영개념을 도입해야 한다. 즉, 정부가 규제완화를 목표로 삼고 있다면 일방적으로 어떤 규제를 완화하겠다고 할 것이 아니라 우선 민간 부문에서 어떠한 규제를 완화하기를 원하는지 파악하여 과감한 완화조치를 마련한 후 관련 부서간 조정을 거쳐 법령을 개폐하는 등 이를 집행하는 것이 중요하며, 마지막 단계로 수혜자인 민간부문의 입장에서 실제 규제완화가 이루어졌는지에 대해 평가하고 평가결과가 계획에 미달할 때는 그 원인을 찾아서 다음 단계의 계획에 반영하며, 성과가 계획목표대로 이루어진 경우에는 해당 집행관료에게 이에 상응하는 대우를 충분히 해주는 등 일련의 사후평가 절차가 반드시 뒤따라야 한다.

The purpose of the study is to examine the visual evaluation of bleeding amount in hemorrhagic shock in paramedic students. Through manikin simulation training, paramedic students were able to have confidence with estimation of bleeding amount in the prehospital settings. Three rescue training manikins were placed in supine position and artificial blood was poured between the abdomen and pelvis. The bleeding evaluations of 700 mL, 1200 mL, and 1700 mL were performed before and after simulation training. Paramedic students underestimated the amount of bleeding in the trauma situation, and it was found that it was difficult for the students to evaluate the accurate amount of bleeding with a single simulation.

Geometric information is a key element for evaluating traffic safety and road maintenance. This study developed an algorithm to identify horizontal alignment using global positioning system(GPS) and inertial navigation system(INS) data. Roll and heading information extracted from GPS/INS were utilized to classify horizontal alignment into tangent, circular curve, and transition curve. The proposed algorithm consists of two components including smoothing for eliminating outlier and a heuristic classification algorithm. A genetic algorithm(GA) was adopted to calibrate parameters associated with the algorithm. Both freeway and rural highway data were used to evaluate the performance of the proposed algorithm. Promising results, which 90.48% and 88.24% of classification accuracy were obtainable for freeway and rural highway respectively, demonstrated the technical feasibility of the algorithm for the implementation.

This paper presents an integrated approach to unconstrained face recognition in arbitrary scenes. The front end of the system comprises of a scale and pose tolerant face detector. Scale normalization is achieved through novel combination of a skin color segmentation and log-polar mapping procedure. Principal component analysis is used with the multi-view approach proposed in[10] to handle the pose variations. For a given color input image, the detector encloses a face in a complex scene within a circular boundary and indicates the position of the nose. Next, for recognition, a radial grid mapping centered on the nose yields a feature vector within the circular boundary. As the width of the color segmented region provides an estimated size for the face, the extracted feature vector is scale normalized by the estimated size. The feature vector is input to a trained neural network classifier for face identification. The system was evaluated using a database of 20 person's faces with varying scale and pose obtained on different complex backgrounds. The performance of the face recognizer was also quite good except for sensitivity to small scale face images. The integrated system achieved average recognition rates of 87% to 92%.

Device of the ECG and pulse signal was made to measure PTT signal using non-invasive method and possible to wearable. PTT alterations were observed according to position change using implemented system.It was needed to ECG and pulse to detect the PTT, used the photoplethymorgraphy appeared to change the blood volume. And also wireless sensor node which was able to Zigbee compatibility was used to transfer the detected ECG and pulse signal to PC. Noise was removed from transit data and algorithm was applied to calculate the PTT. After the evaluation of both the conventional measuring systems and the proposed photoplethymography measuring system, a highly effective and efficient formation and distribution sequences were found within the proposed photoplethymography measuring system.

The purpose of this study was to identify the immediate effect of the joint mobilization with an elastic taping on standing balance in patients with knee osteoarthritis. Thirty patients with knee osteoarthritis were randomly divided into three groups: a taping group, a joint mobilization group, and a joint mobilization with taping group. A foot pressure platform (Zebris) was used to evaluate standing balance ability, and the sway area, path length and average velocity were measured during eyes open condition and eyes closed condition. All the groups showed a significant improvement in the sway area during eyes closed condition after intervention, and the joint mobilization with taping group revealed significant improvements in the path length and average velocity. There was no significant difference in the standing balance ability among all the groups. Both the joint mobilization and taping method were effective methods for standing balance during eyes closed condition, and it has been found that the convergence of the two interventions had an effect on diverse balance variables. Thus, it is recommended to apply the convergence of the two interventions for patients with knee osteoarthritis.
