There are several factors influencing post-operative mortality in Tetralogy of Fallot, such as degree of RV outflow tract obstruction, combined anomaly, and age of the patient. Another factor is preoperative left ventricular volume reported by Kirklin and Graham in 1978. From March to September, 1984, 10 patient with Tetralogy of Fallot have been taken biplane cinecardioangiography [LAO and RAO projection] for measuring left ventricular volume by area-length method. The mean age of the patients was 84.9 [S.D.] and 3 males and 7 females were there. Mean value of left ventricle was 62.9ml/m2, which was no statistically difference from normal value. [p value=0.08]. In conclusion, though this study suggests that there is some decrease of left ventricular end-diastolic volume in Tetralogy of Fallot preoperatively as compared with normal individuals, further evaluation is needed to make it confirmatory with more number of patients and lesser range of age of the patients submitted to the study.

The purpose of this study was to examine the relationships between the interest of apparel ad-vertising direct mail(DM) and the consumers' characteristics ; like their marital state, age, educational level, expenses on clothing purchase, and rigidity. Samples were 243 women(24∼35 years of age) in the Seoul, Korea. The data were analyzed using t-test, one-way ANOVA, Duncan's multiple range test, and discriminant analysis. The results of the study were the followings. 1. The department store sent out the most ap-parel advertising DM and the most common dis-tribution method was carrying the DM with the newspapers, 2/3 consumers paid attention to the contents of the apparel advertising DM with 'some interests'. 2. Jackets and pants were the most purchased items after seeing the apparel advertising DM. 3. The interest in the contents of the apparel advertising DM varied according to the consumers' marital state ad the expenses on cloth-ing purchase. 4. Rigidity, age, educational level, and the clothing purchase expenses contributed to discriminant the interesting or uninteresting group in DM. The accuracy rate of the predicting the groups by the 4 variables was 60.91%.

This study explores the interior image preferred by females living in urban areas. It also examines the relationship between interior image and socio-demographic characteristics such as age, marital status, employment status, total household income. The target population of this study was 301 adult females living in Kwangju City. The data were analyzed with frequency, percentage, General Linear Model, and Duncan's multiple range test using the SAS package. The major findings of this study were as follows. 1) The majority of the females generally preferred modernity of interior image to traditionalism. Also they preferred feminity of interior image to masculinity and complexity to simplicity. 2) Females in the age of 40s were more likely to prefer simple and oriental-traditionalism image to those under the age of 30s. 3) Those with the higher total household income were more 1ike1y prefer western-traditionalism image to those with the lower. But those with the lower household income were more tended to prefer modernity image to those with the higher.

Although there have been wide range of studies to characterize forest stands based upon spectral information of satellite image, it was not fully understood the texture information of forest stand using high resolution data. The objective of this study is to evaluate several texture measures for characterizing forest stand structure, such as species composition, diameter at breast height(DBH), stand density, and age. High resolution IKONOS satellite imagery data were acquired in August 200 lover the forested area near Ulsan, Korea. Primary forest types were plantation pine, mixed forest, and natural deciduous forest of stand age ranging from 10 to 50 years old. Several GLCM-based texture measures were compared with forest stand characteristics. In overall, a texture measure (contrast) calculated using red band were better to differentiate species and age group than other texture measures and near infrared bands.

The purpose of the present study was to investigate the characteristics of metalinguistic awareness of children with specific language impairment. Forty-five children participated in this study; 15 children with specific language impairment (SLI group) whose range of the language age was 4;6-6;6, 15 normal children chronological age matched (CA controls) and 15 normal children language age matched with the SLI group (CA controls). A metalinguistic task involving the identification and revision of syntactic, semantic, and phonologic errors was used. The SLI group performed significantly poorer than CA controls as well as LA controls in identifying and correcting error sentences, especially sentences with syntactic error. These results revealed the relation between language problems of children with SLI and metalinguistic abilities.

We present a study of five open clusters (Alessi 53, Berkeley 49, Berkeley 84, Czernik 5, Pfleiderer 3) based on ugriz images of the Sloan Digital Sky Survey (SDSS). Physical properties of these clusters are not yet well known. The center and size of these clusters are determined using the radial number density profile. Using the proper motion data, we select the members of the target clusters. We estimate physical parameters of the clusters based on the isochrone fitting in the Color-Magnitude Diagram (CMD) : reddening, distance, and age. The foreground reddening is determined to be E(B-V)=0.71-1.55 mag. The distances to target clusters are derived to be 2.0-4.4 kpc, corresponding to the galactocentric distances of 7.5-11.9 kpc. Their ages are in the range of 280 to 1000 Myr. Their spatial distribution in our Galaxy is similar to that of other intermediate-age open clusters. We find ten blue straggler star candidates in Berkeley 49. This number of blue stragglers is a typical value for the age of Berkeley 49.

The focus of this research was to understand the socio-demographic characteristics, pregnancy conditions, social support, and future plan of teenage unwed mothers in Korea. Among the unwed mother, the teenage group was a higher percentage (53.7%) than the over-twenties group (46.3%). In the distribution of teenage unwed mothers, the major part, 94.6%, was in the 16- to 17- year-old age range, and 5.4% were under 15 years of age. This indicates that the age of unwed mothers is getting lower. Most teenage unwed mothers were from intact(72.3%) and/or low-class(62.3%) families. A significant percentage (37.7%)was from middle- and upper-middle class families, signifying that teenage pregnancy is not a problem only of disadvantaged and lower class families. The education of one-third of the teenage unwed mothers in this study was only up to first year of middle school(7th grade), indicating that pregnancy may be a reason they dropped out of school.

The purpose of this study is to investigate the features of Korean infants' vocalizations according to the stages models. A total 88 infants, whose ages range from 1 to 18 months, participated in this study. This age is a critical period for vocal development. However, the study of infants' vocalizations has typically focused on children over the age of two. Because of restrictions related to the study of younger infants, from birth to the age of two, it is usually difficult to investigate what are the major features of their vocal development. Therefore, this study provides documentation and analysis of the features of infant vocalization and their vocal development stages. The results shows that the stages model of Oller & Lynch (1992) might be adapted for Korean infants' vocal development. Furthermore, the features of the infants' vocalization are not linearly appeared one stage to the next stage, but are overlapped (Koopmans-van Beinum & van der Stelt, 1986; Nathani et al., 2006; Oller, 1980; Stark, 1980; Vihman, 1996).
