본 연구는 기존의 서비스디자인 방법론의 소수 데이터를 기반으로 휴리스틱 기반의 연구 한계를 극복하고, 의료서비스의 질적 수준 관리에서 핵심가치로 주목받고 있는 경험데이터의 객관적 측정 및 가공에 관한 모델을 개발하기 위한 연구이다. 이론적 배경에서 의료서비스에서 경험의 중요성, 경험데이터의 측정 및 가공, 환자중심성 실현에 관한 문헌연구를 진행하였다. 이와 같은 문헌 및 이론적 배경 연구결과를 기반으로 다음과 같이 4가지 연구변수에 대하여 조작적 정의하고, 통계적으로 검정을 진행하였다. 가설 H1은 3가지 요인 관점의 경험데이터 측정이 페르소나 모델링에 주는 영향이고, 가설 H2는 페르소나 모델링이 서비스청사진 시각화에 주는 영향, 가설 H3은 서비스청사진 시각화는 환자중심성 실현에 주는 영향, 가설 H4는 페르소나 모델링이 환자중심성의 실현에 주는 영향이다. 요인분석, 신뢰성 분석, 상관분석의 데이터 기초검정 후 회귀분석기법으로 검증한 결과 4가지 가설은 모두 채택되었다. 결론적으로 병원에서 좋은 의료진과 의료장비만을 갖춘다고 해서 그 가치를 인정받기 어려운 시대이기에 환자들에겐 의료진과 의료장비의 효용보다 지속해서 어떠한 의료서비스 경험을 얻고 있는지가 더 중요하다는 의미를 파악할 수 있었다. 서비스 경제의 시대에서 병원서비스 경쟁력의 핵심은 매력적인 경험을 제공하느냐가 병원의 진짜 실력이 되기에 본 연구 주제인 경험데이터의 측정과 가공이 환자중심성의 실현과 스마트병원 구현에 중요한 의미가 있을 것이다.

Objectives : The object of this study is to evaluate and develop the system that reflects acupoints electrical properties by the multi-frequency using the SPAC (Single Power Alternative Current) stimulation method based on BIA (Bioelectrical impedance method). Methods : The 12 channel meridian impedance measurement system (MIMS) was designed, which sets multi-frequency with 10 steps (1~10kHz). To check acupoints electrical properties, impedance of acupoints were measured from 11 acupoints selected from the LU and ST meridians. Results : Regarding distribution of measurement values by multi-frequencies, we found the lowest response at 1kHz was in common. But frequency bands which represent the highest response at each acupoint were various. Measurement values of each acupoint by multi-frequencies were expressed similar distribution (P<0.05). Also we could check same frequency band which showed the highest response at left/right equal acupoints (P<0.05). Conclusions : Through change of acupoints electrical properties by multi-frequency stimulation, we checked oriental medical diagnostic possibilities by using this system. We would progress variable clinical trials with this system for oriental medical diagnosis.

We have shown in Part I [1] of this study that medical needle-stick injuries are causing serious health problems to healthcare personnel and other professionals that require the attention of healthcare and textile researchers to develop new protective systems. Responding to such need, a needle force measurement device that is capable of measuring dynamic forces experienced by medical needles during needle penetration through protective articles was developed and described in part I. This paper reports the results of evaluation of protective woven fabrics from high performance fibers and standard and bifid medical needles using the force measurement system. The woven fabrics varied in cover factor, number of layers, and orientation angle. Standard and bifid needles with different gap widths were used to evaluate the resistance of the fabric to needle penetration.

Objectives: This study aims to investigate whether working environment measurement institutions(WEMIs) are conducting safety and health education, risk assessment, and oversight of special management materials, and whether working environment measurement and special medical examinations are being conducted as prescribed in the Occupational Safety and Health Act(OSHA). Methods: In of February 2021, a questionnaire was prepared and distributed to 33 WMEIs registered with the Ministry of Employment and Labor(MoEL) in Busan and Gyeongsangnam-do Province. The responses were collected and then analyzed. Results: The findings show that 5 WEMIs(15%) complied fully with OSHA. Risk assessment was conducted by 13 WMEIs(39%) and safety education by 11 WMEIs(33%). Eighteen WMEIs(55%) conducted working environment measurement, and 29 WMEIs(88%) conducted special medical examinations. The implementation rate of the risk assessment in the health industry(85%) was higher than the one in the special technology industry(11%)(p<0.05). The implementation rate of the special medical examination in the examiners(54%) was not as high as the one in the analysts(91%)(p<0.05). Conclusions: The MoEL needs to check whether basic OSHA requirements are being observed during regular inspections by WEMIs. These findings indicate that it is necessary to prepare a plan to improve the rate of compliance with OSHA regulations.

광자선 출력측정시 업무 효율을 높이기 위한 소형 물팬톰(듀얼윈도우 팬톰)을 개발하였다. 이 팬톰은 고에너지 광자선의 출력측정뿐만아니라 선질지표의 결정에 적합하다. 이 팬톰은 두개의 창을 가지고 있으며 독립된 두 축에 의해 회전할 수 있도록 제작되어있다. 이 때 두 축은 전리함 이동 없이 조직팬톰선량비와 깊이선량율비를 결정하기 위한 것이다. 코발트조사기와 선형가속기의 고에너지 광자선을 이용하여 팬톰을 평가하였으며, 기준값과 비교할 때 Co-60의 경우 0.2% 그리고 가속기 x-선에 대해 1.4% 이내로 일치하였다. 이 팬톰은 발생 가능한 인적오차를 방지할 수 있기 때문에 일상의 출력측정에 매우 실용적이라고 본다.

전자선 측정에 사용되는 원통형 전리함의 유효 측정점 깊이에 관한 연구를 하였다. 물팬톰 속에서 Markus 평판형 전리함을 사용하여 여러 에너지(전자선 6MeV 및 9MeV, 12MeV, 20MeV) 방사선의 선량 백분율을 구하고, 이 값을 기준으로 하여 원통형 전리함으로(PW233643 내경 5.5mm 및 PR-05P 내경 4mm, PM30 내경 15mm) 구한 선량 백분율과 비하여 선량 백분율 곡선의 변위를 유효 측정점으로 계산하였다. 이 결과 전자선에서는 0.4～0.6r 만큼, $^{60}$Co 감마선에서는 0.3～0.7r 만큼 표면쪽으로 이동한 값을 측정점으로 정하여야 하는 것을 알았다.

Tape measurement for evaluating edema is frequently used by clinicians. The primary purpose of this study is to determine the intertester and intratester reliability of tape measurement carried out by two physical therapists on lower extremities. The intertester and intratester reliability of six anatomical landmarks measurements were determined in six healthy subjects. The measurements were taken in five sessions by each tester. The intraclass correlation coefficients (2,1) were between .87 and .99 for intertester reliability. Intratester reliability was .93 and .99 for A tester and .82 and .99 for B tester. The average range of variation was .13 to .54 in six landmarks. The reliability of six volume measurements was very high. These results support the use tape measurement as a reliable tool for measuring limb girth.

Recently, handy pulse measurement method was introduced by using smart phone camera. However, measured values are not consistent with the variations of external light conditions, because the external light interfere with dynamic range of captured pulse image. Thus, adaptive dynamic range reconstruction algorithm is proposed to conduct pulse measurement robust to light condition. The minimum and maximum values for dynamic ranges of green and blue channels are adjusted to appropriate values for pulse measurement. In addition, sigmoid function based curve is applied to adjusted dynamic range. Experimental results show that the proposed algorithm conducts suitably dynamic range reconstruction of pulse image for the interference of external light sources.

Cancer, like any disease, is a pathologic biological process. Drugs are designed to interfere with the pathologic process and should therefore also be validated using a functional screening method directed at these processes. Screening for cancers at an appropriate time and also evaluating results is also very important. Volumetric measurement helps in better screening and evaluation of tumors. Volumetry is a process of quantification of the tumors by identification (pre-cancerous or target lesion) and measurement. Volumetric image analysis allows an accurate, precise, sensitive, and medically valuable assessment of tumor response. It also helps in identifying possible outcomes such disease progression (PD) or complete response as per Response Evaluation Criteria in Solid Tumors (RECIST).
