This descriptive exploratory study was conducted to analyze the results of developmental screening test using DDST and the follow-up diagnostic evaluation in one public health center, and to evaluate the feasibility of developmental screening in nursing. Samples were 373 children under 6 years who visited the public health center. Mothers' satisfaction on the developmental clinic was also determined. Summaries of the results were as follows:v 1. 0.5% of children in height and 1.9% of children in weight were included in below 3 percentile of Korean children's growth chart, but none of them showed developmental delay. 2. The results of DDST showed 92.1% of subjects were classified as normal, 3.7% as abnormal, and 4.2% as questionable among 354 children. 3. Most of children who showed the abnormal development at the first DDST were confirmed having the developmental delay at the follow-up diagnostic evaluation. On the other hand, most of children who showed the questionable development at the first DDST revealed having the normal development in follow-up screening test. 4. The result of the DDST was influenced by the birth order of the subject and delivery type. 5.The mean satisfaction score by mothers on developmental clinic was 4.35 in 5 Likert scale. In conclusion, we could certain the feasibility and usefulness of developmental screening in community and child care nursing. To fulfil the increasing needs of mothers with infants on the child development, nurses have to provide anticipatory guidance and parent education in addition to the developmental screening test. We hope to expand the developmental screening in nursing field not only of clinical setting but also of community.

The Denver Developmental Screening Test was devised to provide a simple method of evaluating the developmental status of infants and preschool children. To assess the development of Korean children, 667 children (390 boys and 277 girls) between the ages of 2 weeks and 6 years who live in Kwangju city and rural areas in Chonnam were examined according to the DDST. The ages at which 25%, 50%, 75%, and 90% of the children performed each item were calculated for the entire sample. The results of these were compared with the norms of Denver children and other related previous studies in Korea. The development of the boys was also compared with that of the girls, and further the test results of city children and country children were also compared. Girls performed the DDST items in personal-social, fine motor-adaptive and gross motor sectors slightly earlier than boys. In general, however, there were no significant differences in the developmental rate between boys and girls. In all four sectors of the DDST, urban children performed the items significantly earlier than rural children. In comparing Korean children and Denver children, Korean children tended to perform gross motor and personal-social items at a slightly earlier age than Denver children. In the language sector, Denver children tended to perform a little earlier than Korean children. But on the whole there were no significant differences in developmental status between Korean and Denver children. It should be noted that a few items, such as“Uses plurals”, needed to be changed due to the structure of Korean language.

The purpose of this study is to investigate the relationship between family environment and developmental delay in a sample of normal 3-5 years old children. Developmental evaluation is performed using K-DDST II and K-ASQ. Family environment is researched by survey. The survey questions include children's order, family numbers, religion, patient's age, patient's education history. Subject is selected between the age of 3-5 years old children. The test has been conducted to find an interrelationship between a developmental delayed result and family environment. Study has found that there is a strong relationship between developmental delay and children's family environment. Family environment factor includes children's gender, birth order, parent's age, education history. Therefore, developmental evaluation must have consideration on the element of children's family environment for developmental delay test because of a strong relationship between family environment and developmental delay result.

Objective : To explore the effectiveness of sensory integration program of home-based outcomes in child with sensory modulation disorder. Methods : This study used the simple case study. The subjects were three children diagnosed as developmentally delayed who 14 month and 26 month males and a 15 month female. After initial evaluation, parents were educated on sensory diet and Wilbarger protocol method for 30 minutes twice for home-based treatment and asked to make out daily treatment planning. To measure improvement of children, we used for the Denver Developmental Screening Test II(DDST II), Wee Functional Independence Measure(WeeFIM), hand function, functional ability, oral motor function, Sensory Profile(Dunn, 1999). Results : After the home-based program, the scored of the Denver Developmental Screening Test II(DDST II), Wee Functional Independence Measure(WeeFIM), hand function, functional ability, oral motor function, Sensory Profile(Dunn, 1999) were higher rather than initial evaluation after the home-based program. Conclusion : The home-based program is effective for children with sensory modulation disorder but parents had to be educated by therapist specific evaluation and treatment in sensory integration.

Currently changing trends of child health care is demand total health assessment of child including growth and development. This study concentrates on the growth & developmental status of low birth weight infant for help their growth & development. Thus it can be provide a direction for scientific health education and counseling materials by investigating factor of growth & development. The subjects for this study were made up of 40 low birth weight infant who attended the well baby clinic of E university Hospital. The study method used was a questionnaire ＆ anthropometric assessment and DDST for normative data of development. The period for data collection was from July 1st to August 31th, 1982. Analysis of the data was done using percentages, $\chi$$^2$-test Stepwise Multiple Regression. The results of study were as follows. 1. The mean weight of birth was 2,068gm and mean of gestational period was 35.65 weeks. 2. The age at which weight ; 32.5%, head circumference : 67,5% chest circumference : 55.0%, height : 50. 0％ was normal range of physical growth. 3. The reverse age at which social development ; 87.5%, fine motor & adaptive development ; 70.0%, gross motor development ; 72.5% of children Passed by DDST to determine of normal range of development. 4. In the among variables, it was found that the infant who were the higher emotional & verbal response of mother and stimulus environment was the more normal range of weight & development than who was not. 5. The stepwise Multiple Regression between developmental status and predictors-birth order, weight at birth, sex, antenatal care, gestational period-are accounts for 34.1%.

Accurately measuring the hydraulic conductivity of dredged slurry (HCODS) is a difficult task and usually requires highly developed experimental techniques. To resolve such problem, this paper presents a novel laboratory method, where a double drainage sedimentation test (DDST) is proposed to generate a downward seepage after the end of primary consolidation (EOP). Based on the established stress equilibrium equations, it is figured out that the determination of local hydraulic gradients requires the effective stress distribution to be measured. Accordingly, an additional single drainage sedimentation test (SDST) with the same initial water content is performed in the novel laboratory method, which can be utilized to establish the relationship between effective stress and water content for investigated slurry. Thus, HCODS can be determined via a pair of SDST and DDST, with the water contents after the EOP measured. The corresponding calculation procedure is given in details. With a simply-designed settling column, the hydraulic conductivity tests were performed on three types of dredged slurry. The results demonstrated the effectiveness of the novel laboratory method in measuring HCODS.

The problems of growth & development due to maladjustment are gradually increasing while need for the treatment of children's diseases is decreasing. The level of developmental deficiency or delay correlates with neonatal birth weight and also with gestational age, i.e. degrees of prematurity. There-fore, developmental defects and potential risk factors' are more Common in premature infants than in full term infants. The purpose of this study is to define the difference in the growth at developmental status between premature and full term infants, and to define the relation between the developmental status and the physical growth during the first 3 years' Data were collected from January 10, 1985 to April 6, 1985 at 3 hospitals including St. Mary's Hospital, and through home visiting. The subjects of this study consisted of 79 Premature infants (G.A. <37wks. & B.W. <2.5kg) and 94 full term infants (G.A.≥37 wks. & B.W.≥2.5kg). The study method used was a questionnaire, anthropometric assessment and DDST for normative data of growth & development. The collected data were analyzed using descriptive statistics, chi-square test and t-test. The results of the study were as follows: Hypothesis: 1 : That the prematures will differ from the full term infants in the physical growth status during the first 3 years was partially supported (p＜0.02) : The prematures reached up the full term infants in the physical growth status in the first 6 months. And, the first hypothesis was supported (P<0.01) : There are more cases which is below‘the Korean children's physical. growth standards’in prematures than in full term infants. Hypothesis 2 : That the prematures will differ from the full term infants in the developmental status during the first 3 years was supported (P< 0.001)；‘Normal’developmental status due to DDST was less in prematures than in full term infants. And, the second hypothesis was Partially supported (P<0.02) : The developmental status of the pre-matures was different from that of the full term infants within the first 3 months by analysis of passed items in DDST, Hypothesis 3 : That the prematures' developmental status will relate to their physical growth during the first 3 years was supported (P<0.001) : If the prematures' developmental status is in delayed status, then, their physical growth status is also in delayed status. This study shows that the prematures differed significantly from the full term infants in the growth at developmental status during their infancy. This means that the nurse can foster the growth & development of the prematures by supportive care during their infancy. Further longitudinal study is needed to verify these findings for the environmental factors.

This study were conducted to assess the physical growth and developmental status of infants in orphanage in order to provide an empirical data. The subjects for this study were 104 infants and toddlers who were reared in an orphanage in D Metropolitan city. The instrument used for this study were anthropometric assessment and DDST for normative data of development. Data has been collected from September 1st, 1998 to August 31st, 2000 and were analyzed using SPSS/PC(Version 10.0) with frequency, mean, standard deviation, ANOVA and Chi-square test. The results of this study were as follows; 1. 30.8% of infants in orphanage had abnormal weight, 26.9% had abnormal length, and 22.1% had abnormal head circumference and most of them were distributed below 50 percentile of growth chart. 2. 53.8% of infants in orphanage had normal, 27.9% had qustionable, and 18.3% had abnormal developmental screening test results, especially, 31.5% of infants in orphanage ages 3 to 5 years had abnormal developmental screening test results, according to the Denver Developmental Screening Test(DDST). There was a significant developmental delay noted in the language and fine motor-adaptive sector. 3. It is anticipated that developmental delays would increase in severity by older the mean age of orphanage infants and longer the time being raised in orphanage. It would be concluded that the physical growth and developmental status of orphaned infants were very vulnerable and serious and it is suggested that there needed an effective intervention strategies to promote growth and development of infants in orphanage.

We compared three EDTA-based phenotypic screening methods for detecting IMP-1 and VIM-2 type metallo-${\beta}$- lactamase (MBL)-producing isolates of Acinetobacter and Pseudomonas spp., EDTA-double disk synergy test (EDTADDST), Etest MBL, and imipenem (IPM)-EDTA disk test. A total of 183 isolates (65 Acinetobacter spp. and 118 Pseudomonas spp. showing IPM resistance), confirmed to MBL genes by PCR, were used. The criteria for MBL production were (i) presence of a synergistic zone between IPM and EDTA disks in EDTA-DDST, (ii) reduction of IPM minimal inhibitory concentration by ${\geq}$ 3 twofold dilutions in the presence of EDTA in the Etest MBL, and (iii) ${\geq}$ 7 mm increase in the inhibition zone around the IPM plus EDTA disks compared with a sole IPM disk in the IPM-EDTA disk test. In this study using 87 MBL-producing and 96 MBL-nonproducing isolates, the sensitivities/specificities of EDTA-DDST, Etest MBL and IPM-EDTA disk tests were 94.3/78.1%, 89.7/91.7%, and 97.7/95.8%, respectively. When the threshold for the increase of the inhibition zone around the IPM plus EDTA disk over a sole IPM disk was altered to ${\geq}$ 5 mm and ${\geq}$ 8 mm for Acinetobacter spp. and Pseudomonas spp., respectively, the sensitivity and specificity of the test were 98.9% and 96.9%, respectively. Of the three EDTA-based phenotypic tests, the IMP-EDTA disk test was superior for detection of MBL-producing isolates.
