The purpose of this study was to evaluate the maternal perception of her newborn and identify the risk of mother-infant relationship. Broussard's Neonatal Perception Inventories were completed by 113 mothers on the first or second postpartum day (Time I ) while they were still in the University Hospital. These inventories were again administered when the infants were approximately one month of age (Time Ⅱ). The data was analyzed by S.P.S.S. program and the results were as follows: 1) There were differences between the mothers' exportations of the average baby and perceptions of their babies at Time I and Time Ⅱ (p<0.01). 2) The maternal perception of her newborn at Time I was not related with the education, the parity, the experience of abortion, the type of delivery and the sex of baby but related with the method of feeding (p<0.05). 3) The maternal perception of her newborn at Time Ⅱ was not related with the education, the parity, the experience of abortion, the type of delivery and the method of feeding but related with the sex of baby (p<0.05). 4) The changes of maternal perception between Time I and Time Ⅱ were not related with the education, the parity, the experience of abortion, the method of delivery and the sex of baby but related with the method of feeding (p<0.1). 5) The maternal perception of the newborn was not correlated with the age and the duration of labor.

The process of breast feeding was investigated from the 36th week of pregnancy to 12 weeks postnatal, in order to analyze the factors affecting breast feeding duration and provide the basic data on an education program for successful breast feeding. The general characteristics of study group had no marked effects on the breastfeeding duration. The young and highly condition during pregnancy and the degree of morning sickness affected the practice of breastfeeding. In the study of prenatal sociobehavioral factors, intended duration affected the breastfeeding duration, and the maternal perception that breastfeeding is good for weight loss after delivery as well as infant formula milk is not as good as breast milk, led to successful breast feeding. Among the postnatal biological factors, the duration of gestation affected the breast feeding. Among the postnatal biological factors, the duration of gestation affected the breastiffeding outcome. In the case of early parturition, breastfeeding rate was low. Among the postnatal biocultural factors, time of first feed, milk volume and maternal perception of infant's sucking ability affected the bresatfeeding duration. From these result, it is suggested that an education program such as participation of nursing class to the pregnant women should be provided for successful breastfeeding.

현재 국내 건설산업에서의 공정계획은 합리적인 사전계획 없이 현장기술자의 경험과 능력에 따라 계약공기에 맞추는 방식으로 추진되고 있다. 또한 공정계획의 핵심인 광기산정은 업체마다 서로 차이를 보이고 있어 객관적인 공기산정이라고 할 수 없는 실정이다. 이러한 공정계획의 부실은 공정계획 현장 적응 시 공기 및 작업순서의 차이를 발생시켜 효과적인 공정관리가 이루어지지 못하는 원인이 되고 있으며, 다양한 공기지연 사유가 발생하고 있다. 본 연구에서는 현재 제조업에서 적용중인 제약이론 기반의 CCPM(Critical Chain Project Management)의 확률적 공기산정과 공정버퍼의 개념을 건설 프로젝트에 적용하여 합리적인 공정계획 수립 방안을 제시하였다.

The study examined the effects of San-Yin-Jiao(SP-6) acupressure treatment on labor pain, length of delivery and anxiety for women in the labor. The effects of using SP-6 acupressure were evaluated by comparing two groups, a SP-6 acupressure group (22) and a control group (17), for a total of 39 women in labor who had a normal vaginal delivery. Data were collected using a structured questionnaire which included general characteristics, a subjective labor pain scale, measurement of duration of delivery time and a subjective anxiety scale. Data were collected before treatment (pre) and after treatment (post). The results of this study are summarized as follows : 1. The post-scores for total labor pain increased over the pre-scores but the difference between the two groups was not statistically significant(p=0.219). Wilcoxon signed rank test of the difference in pre-post labor pain scores for the SP-6 acupressure group was not statistically significant (p=0.081) but the increase for the control group was statistically significant (p=0.001). 2. The length of time for the delivery in the group which had the SP-6 acupressure was shorter (143.91${\pm}$67.77) than the control group (197.94${\pm}$89.64). The difference between the two groups was statistically significant (p=0.028). 3. The post-scores for anxiety increased over the pre-scores but the difference between the two groups was not statistically significant (p=0.426). The scores of SP-6 acupressure group did not show a significant increase by the Wilcoxon signed rank test (p=0.194) but in the control group showed a significant increase (p=0.008).This study showed that SP-6 acupressure was effective in relation to labor pain, length of time for delivery and anxiety for labor women. But it is necessary to replicate the study with a larger number of participants to generalize the results.

Purpose: Poloxamer 407 (P407) thermo-sensitive hydrogel formulations were developed to enhance the retention time in the urinary bladder after intravesical instillation. Materials and Methods: P407 hydrogels (P407Gels) containing 0.2 w/w% fluorescein isothiocyanate dextran (FD, MW 4 kDa) as a fluorescent probe were prepared by the cold method with different concentrations of the polymer (20, 25, and 30 w/w%). The gel-forming capacities were characterized in terms of gelation temperature (G-Temp), gelation time (G-Time), and gel duration (G-Dur). Homogenous dispersion of the probe throughout the hydrogel was observed by using fluorescence microscopy. The in vitro bladder simulation model was established to evaluate the retention and drug release properties. P407Gels in the solution state were administered to nude mice via urinary instillation, and the in vivo retention behavior of P407Gels was visualized by using an in vivo imaging system (IVIS). Results: P407Gels showed a thermo-reversible phase transition at $4^{\circ}C$ (refrigerated; sol) and $37^{\circ}C$ (body temperature; gel). The G-Temp, G-Time, and G-Dur of FD-free P407Gels were approximately $10^{\circ}C-20^{\circ}C$, 12-30 seconds, and 12-35 hours, respectively, and were not altered by the addition of FD. Fluorescence imaging showed that FD was spread homogenously in the gelled P407 solution. In a bladder simulation model, even after repeated periodic filling-emptying cycles, the hydrogel formulation displayed excellent retention with continuous release of the probe over 8 hours. The FD release from P407Gels and the erosion of the gel, both of which followed zero-order kinetics, had a linear relationship ($r^2=0.988$). IVIS demonstrated that the intravesical retention time of P407Gels was over 4 hours, which was longer than that of the FD solution (<1 hour), even though periodic urination occurred in the mice. Conclusions: FD release from P407Gels was erosion-controlled. P407Gels represent a promising system to enhance intravesical retention with extended drug delivery.
