The purpose of this study was to develop a parenting intervention program and determine the efficacy of the program with low-birth weight infants and their mothers. Nine dyads for the experimental group and twelve dyads for the control group discharged from the Neonatal Intensive Care Unit of a University Hospital in Seoul were recruited for the study. For the intervention group, programmed education and support which focused on the maternal sensitivity of the infant's behavior. rearing environment. motherinfant interaction and infant care were given to each subject. Individual counseling and home visits were provided at discharge, one week after discharge. and one and three months of corrected age in every infant. Structured questionaires were administered and feeding interactions were videotaped and coded by a blinded certified observer. A Quasi-experimental design was conducted for this study. Postpartum depression, maternal self esteem. infant care burden, HOME. mother-infant interaction, and infant development were measured. Results were in favor of the intervention versus the control group. On the Beck depression inventory, intervention mothers showed decreasing trends in depressive symptom vs control mothers although, there were statistically no significant differences between the two groups at each time. The mean score of experimental group was 11.55(mild depression state) at discharge and became 8,6(normal state) at 1 month of corrected age. On the other hand, the mean score of the control group was 13.92(mild depression state) at discharge and became 14.0. Maternal self esteem in both groups improved over time. Infant care burden in both groups was also shown to increase over time. There was a significant difference between the two groups in HOME(p=.0340) at 3 months of corrected age. HOME scores of the experimental group and the control's were 31.10 and 25.58, respectively. Mothers' emotional and language responses were significantly high in the intervention group compared with the control group(p=.0155). Intervention group (53.33) showed a significantly high quality of motherinfant interaction compared with the in control group (42.80)(p =.0340). Intervention group mothers appeared have a better quality of mother-infant interaction behaviors. On the other hand, there was no statistical difference in the infant part between groups. Intervention group infants had higher trends in a general developmental quotient: although, there was no statistical difference between groups. The general developmental quotient of intervention infants was 102.56 and control's was 91.28. However, the developmental quotient of the domain of 'individuality-sociality' was higher in the intervention group infants compared with the control's(p=.0155). The concerns identified by parents revealed two domains of an infants' health management -knowledge and skills in caregiving of lowbirthweight-infants, characteristics of lowbirthweight infants, identifying a developmental milestone, coping with emergency situations and relaxation strategies of mothers from the infant care burden. Interview data with the mothers of low-birth weight infants can be used to develop intervention program contents. Limited intervention time and frequency due to time and cost limitations of this study should be modified. The intervention should be continuously implemented when low-birth weight infants become three years old. An NNNS demonstration appeared to be a very effective intervention for the mothers to improve the quality of mother-infant interactions. Therefore intervening in the mothers of low-birth weight infants as early after delivery as possible is desirable. This study has shown that home visit interventions are worthwhile for mothers only beyond the approach as an essential factor in ability of facilitating a growth fostering environment. In conclusion. the intervention program of this study was very effective in enhancing the parenting for the mothers of low-birth weight infants, resulting in health promotion of low-birth weight infants. The home-visit outreach intervention program of this study will contribute to the health delivery system in this country where there is a lack of continuous follow-up programs for low-birth weight infants after discharge from NICU, if it is activated as part of the home visit programs in community health systems.

Effects of the gardening program on the mentally retarded persons were assessed on the inadaptive behavior and the social maturity for 1 to 2 years and 2 months in Seoul Welfare Center for the Mentally Retarded. The results were as follows; 1. The mentally retarded persons treated with the gardening program for 1 to 2 years and 2 months showed and improvement of the inadaptive behavior as compared with the pre-gradening program. The second(the enervation and the social isolation) and fourth (the excessive behavior and the deviant behavior) sects among the four of Inadaptive Behavior Checklist showed and improvement of the inadaptive behavior. And first sect(crying, excitement, and anger) of Inadaptive Behavior Checklist greatly showed and improvement of the inadaptive behavior. 2. The mentally retarded persons were improved in their social maturity through the gradening program for 1 to 2 years and 2 months as compared with pre-gradening program. Both a social age and social quotient were quite a bit increased. 3. Females showed improvment in the inadaptive behavior and the social maturity by the gardening program when compared to males, but the difference between male and female was not striking. 4. Both the higher IQ group from 55 to 70 and the lower IQ group from 40 to 54 showed improvment in the inadaptive behavior by the gardening program, but the difference between two groups was not obvious. However, the higher IQ group through the gardening program increased the social maturity more than the lower IQ group. 5. In both the gardening program periods for 1 to 1 year and 2 months and those for 2 years and 2 months the inadaptive behavior and the social maturity showed an improvment when compared to pre-gardening program, but the difference between two groups was not conspicuous.

Objective: The objective of this study was to evaluate the osseointegration of narrow-diameter implant with trapezoid-shape and to evaluate the effect of coronal microthreads on trapezoid-shape narrow-diameter implant. Materials and Methods: The experimental narrow-diameter implants were classified into two groups according to absence or presence of coronal microthreads: trapezoid-shape narrow diameter implant (TN group) and trapezoid-shape narrow-diameter implant with microthreads (TNM group). They were installed alternately in bilateral mandible in three dogs. After 8 weeks, the animals were sacrificed. Resonance frequency analysis, removal torque test, and histometric analysis were performed. Results: Statistically higher implant stability quotient (ISQ) values were observed in TNM group than in TN group at the time of implant installation. However, significant ISQ values difference was not observed between groups at 8 weeks. Both groups showed significantly increased ISQ values at 8 weeks, compared to the time of implant installation. There was no significant difference between groups in removal torque test. Bone-implant contact ratio also showed no significant difference between groups in total and coronal part. Conclusion: Within the limitation of this study, it could be concluded that the trapezoid-shape design on narrow-diameter implant showed successful ossointegration, and the microthreads on coronal part did not result in significant bone-implant contact and biomechanical stability at 8 weeks.

The purpose of this study was to determine if any differences exist in eye contact before and after vestibulaar stimulation in mentally retarded children. The subjects of this study were 20 mentally retarded children with a mean age of 9 years and 8 months and a mean intelligence quotient of $30.4{\pm}9.1$. Vestibular stimulation was given for 15 minutes, 5 times a week, for 4 weeks from September 1 to September 30, 1989. Equipment used included a rocking-horse, see-saw and scooter board. Two testers used a digital watch calibrated to 1/100 second to measure object-eye contact duration and the Blocks and Shapes test for determining frequency of object-eye contact in the subjects. The results of this study were as follows : 1. There was a significant prolongation in the duration of eye contact after 15 minutes of vestibular stimulation (p<0.005). 2. There was no significant difference in duration of eye-object contact between the first and last vestibular stimulation. 3. There was no significant difference in the length of time of attention paid to objects (frequency of eye-object contact) before and after 15 minutes of vestibular stimulation on the first vestibular stimulation. 4. There was no significant difference in the frequency of eye-object contact between the first and first vestibular stimulation. In conclusion, there was u significant improvement in duration of eye-object contact on intrasession measurement in mentally retarded children. However, there was no significant improvement over time after 4 weeks of vestibular stimulation on intersession measurement. Nor was there any statistically significant improvement in frequency of eye-object contact over time during the study period.

연구 목적: 이 연구의 목적은 임플란트의 직경, 길이 및 디자인의 변화가 임플란트 안정성 지수에 미치는 영향을 비교하는 것이다. 연구 재료 및 방법: 골질차이에 의한 변수를 제거하기 위해 상악골 평균밀도와 유사한 균일한(0.48g /$cm^3$) 밀도를 가진 Polyuretane foam blocks (Sawbones$^{(R)}$, Pacific Research Laboratories Inc, Vashon, Washington)을 이용, 임플란트(Implantium$^{(R)}$, Dentium, Seoul, Korea)를 다양한 직경(${\phi}3.8$, ${\phi}4.3$ 및 ${\phi}4.8$)과 길이(8, 10 및 12 mm)로 식립하여 그 변화가 임플란트 안정성 지수(Implant Stability Quotient, ISQ)에 미치는 영향을 비교하였다. 또 같은 직경과 길이(${\phi}4.3{\times}10mm$)에서 submerged와 non-submerged (SimplelineII$^{(R)}$, Dentium, Seoul, Korea) 디자인이 ISQ 에 미치는 영향을 비교하였다. 식립 회전력의 영향을 배제하기 위해 동일한 35 N의 Torque로 각 실험군당 10개씩 총 60개의 임플란트를 식립하였다. Osstell$^{TM}$ mentor(Integration Diagnostic AB, Sweden)를 이용하여 공진주파수를 측정한 후 ISQ 값으로 기록하였고, 그 결과를 one-way ANOVA와 Tukey HSD test로 분석하였다(${\alpha}$=.05). 결과: 1. 임플란트 직경의 변화는 ISQ에 영향을 미치지 않았으나(P>.05), 임플란트 길이가 증가함에 따라 ISQ도 증가하였다(P<.001). 2. 임플란트 디자인의 변화는 ISQ와 유의한 상관관계를 보여 Submerged 디자인의 ISQ가 non-submerged 디자인보다 높게 나타났다(P<.05). 결론: 임플란트 안정성을 높이기 위해서는 가능한 길이가 긴 임플란트를 식립하는 것이 유리하며, 같은 길이의 임플란트에서 볼 때 Non-submerged 디자인보다 submerged 디자인이 더 높은 ISQ를 얻을 수 있을 것으로 생각된다.

Purpose: This experiment examined the effect of different surface treatment on the osseointegration and stability of implants. Material and methods: In this study, 40 each of machined, SLA and RBM implants, which are the most commonly used implants, were implanted into the tibia of 20 normal rabbits using $OsseoCare^{TM}$. The rabbits were sacrificed after 1 week, 4 weeks, 8 weeks and 12 weeks for implant stability analysis, removal torque analysis, histologic and histomorphometric analysis. Result : ISQ showed significant difference between Machined and RBM at first week and at 4 weeks. There was significant difference between Machined and both SLA and RBM(p<0.05) but after 8 weeks there were no significant difference between each group. In the removal torque, RBM showd significantly higher values than SLA and Machined surface at 1st week. At 4th and 12th week, there was significant difference between Machined and SLA, RBM(p<0.05). In the bone to implant contact variable, there was no significant difference between each surface treatment method. In the Machined surface group, there was no significant difference between each time interval. but in SLA group, there were significant differences between the 1st week and 12th week and in RBM group, there were significant differences between the 1st week and 8th, 12th week and between 4th and 12th week(p<0.05). The bone area showed significantly higher values in SLA and RBM compared to Machined surface 1st and 8th week and significantly higher values in SLA than Machined surface at the 4th week(p<0.05). Conclusion: The roughened surface of implants showed positive effect in the early stages of implantation and assisted in bone formation After the bone formation stage, there was no statistical difference between Machined and roughened surface groups. In dental implantation, where initial stability is critical to the success of implants, the use of roughened surface implants should assist in reducing the healing period after implantation.

The concepts of reversible, right duo, and Armendariz rings are known to play important roles in ring theory and they are independent of one another. In this note we focus on a concept that can unify them, calling it a right Armendarizlike ring in the process. We first find a simple way to construct a right Armendarizlike ring but not Armendariz (reversible, or right duo). We show the difference between right Armendarizlike rings and strongly right McCoy rings by examining the structure of right annihilators. For a regular ring R, it is proved that R is right Armendarizlike if and only if R is strongly right McCoy if and only if R is Abelian (entailing that right Armendarizlike, Armendariz, reversible, right duo, and IFP properties are equivalent for regular rings). It is shown that a ring R is right Armendarizlike, if and only if so is the polynomial ring over R, if and only if so is the classical right quotient ring (if any). In the process necessary (counter)examples are found or constructed.
