Measurement of complex surfaces without touching is desirable in several fields. This arises mainly for measurement of complex surfaces including those surfaces that deform during touch. Our research presented in this paper describes the use of a 3D digitizer for scanning 3D objects. The use of such a device, in addition to proper calibration, requires proper scaling in all three dimensions. We propose measurement techniques to measure various aspects of the surface circumference, area and volume. We also present experiments from using a 3D Minolta digitizer for measuring 3D human heads.

Purpose: This study was done to identify pain perception (P-PER) by nurses and pain expression (P-EXP) by patients in critical care units (ICUs) and degree of agreement between nurses' P-PER and patients' P-EXP. Methods: Nurses' P-PER was measured with a self-administered questionnaire completed by 99 nurses working in ICUs during May, 2013. Patients' P-EXP was measured with the Critical Care Non-Verbal Pain Scale through observations of 31 ICU patients during nine nursing procedures (NPs) performed between May and July, 2013. Results: Nurses' P-PER was from 4.49 points for nasogastric tube (NGT) insertion to 0.83 for blood pressure (BP) measurement based on a 9-point scale, Patients' P-EXP was 4.48 points for NGT to 0.18 for BP measurement based on a 10-point scale. Eight NPs except oral care showed higher scores for nurses' P-PER than for patients' P-EXP. Position change (p=.019), subcutaneous injection (p<.001), blood sugar test (p<.001), and BP measurement (p<.001) showed significant differences between nurses' P-PER and patients' P-EXP. Conclusion: Nasogastric tube (NGT) insertion was scored highest by both nurses and patients. Eight NPs except 'oral care' showed nurses' P-PER was higher or similar to patients' P-EXP, which indicates that nurses may overestimate procedural pain experienced by patients.

클러스터는 병렬 컴퓨팅 및 데이터 센터에 적합한 구조를 제시하지만 설계 빛 확장을 할 때 성능에 대한 예측이 쉽지 않다 또한 기존의 클러스터 성능 분석은 이미 구성된 시스템만을 그 대상으로 한다는 문제점을 가지고 있으며 클러스터의 확장 및 대용량 클러스터에 대한 성능 예측을 지원하지 못한다. 그러므로 기존에 대규모 클러스터를 평가하던 방법들과는 다른, 시스템 구성 전 대규모 클러스터를 위한 모델링 및 예측 방법을 필요로 한다. 이러한 작업은 클러스터의 구조적 특성이 잘 반영되어야 하며 실제 시스템 적용 시 나타나는 문제에 관해서도 분석이 쉽게 되어야 한다. 본 논문에서는 대규모 클러스터의 성능 모델링을 위한 방법론을 제시하고 실제 시스템에서 수행한 측정 및 예측 결과로 방법론의 유용성을 보인다.

Spasticity, an abnormal increase in resting muscle tone, is one of the most common symptoms of stroke, and its management is becoming a major issue in rehabilitation. The aims of this study are to determine the effects of electroacupuncture(EA), TENS and neuromuscular electric stimulation(NMES) on spasticity, as well as the possibility of tissue comliance method as a spasticity scale. 45 stroke patients participated in a study of the effects on hemiplegic spasticity of EA, TENS and NMES. Spasticity was measured by modified Ashworth scale on the upper extremity and tissue compliance measurement, penetration mm/kg, on Susamni(LI10) area at just before and after stimulation, and 30 minutes, 1 hour, 2 hours and 24 hours after stimulation. The acupuncture points were applied to Kokchi(LI11), Susamni(LI10), Hapkok(LI4) and Oegwan(TE5) of the affected limb. The electrodes were placed unilaterally on LI11 to LI10 and TE5 to LI4. EA with biphasic wave, 60Hz, 0.4 msec pulse duration and low intensity was applied continuously for 20 minutes. TENS with high frequency, low intensity was applied. NMES was applied with spasticity program for 20 minutes. Each electric stimulation was done on extensor muscles group of forearm for 20 minutes. EA and NMES groups were found to produce a statistically significant decrease(p〈0.05) of spasticity and these effects lasted up to 30 minutes after stimulation. There was no definite correlation between the modified Ashworth scale and tissue compliance measurement. But tissure compliance method was found to be possible as a quantitative measurement on spasticity. There was no significant correlation between the effects of EA and NMES and the characteristics of patient, but significant correlation between the effects of EA and NMES and the modified Ashworth scale.

SWLS(Satisfaction With Life Scale)는 국내외에서 가장 많이 사용되는 삶의 만족도의 측정도구이다. 본 연구는 연령과 성별이 다른 집단에서 SWLS의 요인구조와 측정동일성을 검토했다. 성인 초기 대학생 433명(남자 195명, 여자 238명)과 중년기 성인 503명(남자 237명, 여자 266명)으로 구성된 총 936명의 자료를 분석한 결과는 다음과 같다. 첫째, 확인적 요인분석을 사용하여 SWLS의 요인 구조를 검토했을 때, 4번과 5번 문항간 잔차를 허용한 수정된 단일요인모형이 지지되었다. 따라서 SWLS는 한국에서도 과거 시점을 반영하는 4번과 5번 문항이 다른 문항들과 구별되는 속성을 공유하는 것으로 확인되었다. 둘째, SWLS는 남성과 여성 집단 간에 형태, 요인부하량, 절편, 오차변량의 동일성이 모두 지지되었다. 그러나 대학생과 중년의 성인 집단 간에는 부분측정동일성만이 지지되었다. 이러한 결과는 SWLS 척도를 사용하여 한국인의 연령 및 성별 삶의 만족도를 비교하는 것이 가능하지만, 연령차를 해석할 때에는 보다 세심한 주의를 기울일 필요가 있음을 시사한다.

Purpose: Recently, Korean cosmetics distribution market has been reorganized with the H&B store. In the domestic cosmetics distribution market, existing brand road shops are decreasing, and multi-shops are leading the H & B stores, which have greatly improved their experience and content. In these environmental changes, the offline distribution channels are turning into the multi-editing shops that have introduced products of various brands and greatly enhanced experiences and contents. Nevertheless, most studies of factors and measurement items for measuring customer experience in the H&B store use Schmitt (1999)'s Strategic Experience Modules (SEMs). Therefore, the purpose of this study is to propose a measure that is practicable through consideration of the in-store customer experience components of the H&B store. Research design, data and methodology: Based on Schmitt's Strategic Experience Modules (SEMs), which are widely used in customer experience marketing, the metric pool was constructed through customer and literature research on H & B store managers. Since then, 101 preliminary surveys and 211 main surveys have been conducted in order to propose a dimension of customer experience and refine the metrics. Results: As a result of the research, H&B store's customer experience was derived from a measurement model consisting of 19 measurement items in total of five dimensions: environmental experience, intellectual experience, behavioral experience, tech experience, and relationship experience. This study analyzed that compared to the existing Schmitt's Strategic Experience Modules (SEMs), (1) emotional experience expanded to environmental experience, (2) Cognitive and relationship experiences are maintained (3) behavioral experience was subdivided into physical and technical experiences. In particular, the environmental experience has been proposed as a major component is an important point because the H&B store recently opened a large flagship store and is competitive in constructing a differentiated space. Conclusions: Related experience was seen as an important component of customer experience in the offline store, but in the process of refining the scale, interaction items with employees of the H&B store were removed, and rather, participation in the APP or SNS channel of the company, event Participation, interaction with other customers, etc. appear to be important, while suggesting the practical implications.

Atomic force microscopy (AFM) has been widely utilized as a versatile tool not only for imaging surfaces but also for understanding nano-scale interfacial phenomena. By measuring the responses of the photo detector due to bending and torsion of the cantilever, which are caused by the interactions between the probe and the sample surface, various interfacial phenomena and properties can be explored. One of the challenges faced by AFM researchers originates in the physics of measuring the small forces that act between the probe of a force sensing cantilever and the sample. To understand the interactions between the probe and the sample quantitatively, the force calibration is essential. In this work, the procedures used to calibrate AFM instrumentation for nano-scale force measurement in normal and lateral directions are reviewed.
