While the society becomes older, the quality growth on the service adequate to seniors is required. The service design is highlighted as a measure to improve the quality of service. And actually, success cases through the service design in various areas are globally introduced. In this study, a research is conducted to develop a service scenario to expand seniors’ communication by applying the service design methodology. To analyze seniors’ behaviors related to the communication, profiles are established by performing interviews with professionals and the qualitative survey to seniors. And based on the profiles, an idea workshop is conducted with multi-disciplinary experts to develop ideas for seniors’ communication. The representative service is drawn by refining ideas. And the detailed service scenario and the video prototype are developed by concentrating one service scenario. The developed service scenario is anticipated to be utilized as a base material to develop services to expand seniors’ communication in the future.
자궁내 태아발육지연 예측에 있어서 태아 Ponderal index의 임상적 의의
차상헌,유훈 순천향대학교 1986 논문집 Vol.9 No.3
The ponderal index describes the relationship between weight and crown-heel length of the neonate based on the equation: Neonatal ponderal index=weight/ length³×100. The ponderal index is a sensitive method to diagnose asymmetrically growth retarded infants. Until recently, calculation of ponderal indexes in the fetus has not been possible. With recent advances in the real-time ultrasound technology, it is possible to calculate the ponderal index in utero. The present study was designed to determine the relationship between the ultrasound fetal ponderal index and the neonatal ponderal index found at birth, and to evaluate the efficacy of the fetal ponderal index in predicting intrauterine growth retardation in infants with neonatal ponderal indexes below the tenth percentile for age. The results obtained were as follows: 1. There was no significant difference between the mean prenatal and postnatal values for weight, length, and ponderal index. 2. 15 of 125 cases(12%) had neonatal ponderal indexes below the tenth percentile for age at birth. Of these, 11 had also fetal ponderal indexes below the tenth percentile(sensitivity 73.3%). Of the 110 remaining infants with normal neonatal ponderal indexes, 87 had also normal fetal ponderal indexes(specificity 79.1%). 3. There were 33 infants with fetal ponderal indexes below the tenth percentile but 11 had neonatal ponderal index below the tenth percentile at birth(positive predictive value 33.3%). 4. Of the 92 with normal fetal ponderal indexes, 88 were also normal at birth(negative predictive value 95.7%). In conclusion, it is suggested that the calculated fetal ponderal index could be used to rule out fetal growth retardation with reasonable accuracy.
