The purpose of this study was to determine the drinking behaviors and drinking problems of adult, mentally retarded persons over 18 years old. It was also investigated whether gender, age, and pattern of employment create different result of drinking behaviors and drinking problems, and the variables explaining drinking problems were analyzed. One hundred forty adults, mentally retarded persons were surveyed in Seoul and KyeongGi area. The major findings were as follows; The majority of respondents ($58.2\%$) reported that they had consumed alcohol beverages sometimes prior to their having been interviewed. The average age of respondents who had consumed alcohol was 26.4 years and average age of first-use of alcohol was 22 years. For consumption frequency, $39.2\%$ of respondents reported that they drink alcohol once a month. Average alcohol consumption per occasion was 1.5 cups, and $10.9\%$ of respondents answered more than 5 cups per occasion. Regarding problems associated with drinking, $16\%$ of respondent of AUDIT and $51.4\%$ of Family CAGE answered that their children have drinking-related problems. Men drink more than women and experience more alcohol problems. Supervised employment group was the group with the greatest prevalence for drinking. For the amount of drinking, gender and employment pattern showed significant differences. Drinking problems (AUDIT and Family CAGE) of adult, mentally retarded persons were influenced by age of first-use of alcohol, frequency of alcohol use, and alcohol consumption.

This study was designed to investigate the effects of dietary protein and caffeine consumption levels on Ca, P, Na and K metabolism. One hundred twenty rats were divided into twelve groups according to age, protein level and caffeine consumption such as group(120-130g young rat, 250-300g adult rat) , dietary protein group (20% normal protein , 85 low protein) , caffeine consumption group(0, 3.5mg, 7.0mg). Low protein diet containing high caffeine levels caffeine levels increased calcium, phosphorus, sodium and potassium contents of urine and fecal in rats. Young rat has higher level of calcium, phosphorus , sodium and potassium than adult rat. In the serum, calcium contents were not affected by age, dietary protein levels and caffeine consumption . However, phosphorus, sodium and potassium contents of serum in adult rat were higher than young rat. In the liver, potassium decreased with decreasing dietary protein levels. In the kidney, calcium , phosphorus and potassium contents were not different by age group, dietary protein levels and caffeine consumption , but sodium content was significantly reduced in the adult rat.

The author studied on the dental arch widths and lengths and height of palates at 3 groups of dentition: mixed dentition, early permanent dentition, young adult, having normal occlusion and dentition. The models of the 336 maxillary and mandibular case, made from alginate-base hydrocolloid impressions were measured and analyzed statistically. The result as follows; 1. The upper intercanine width increased between the mixed dentition group and early permanent dentition group but there was no change in the young adult group in both sexes. The lower intercanine width increased between the mixed dentition group and early permanent dention group in the male. 2. The upper and lower 1st bimolar width increased slightly with age in the male but there was no change in the female. 3, The sex difference found in this study was one of absolute size, the female being slightly smaller than the male in the early permanent dentition group and young adult. 4. The arch length had no notable sexual differences and decreased between the mixed dentition group and early permanent dentition group. There was no change in the arch length in the young adult. 5. The height of palate increased gradually with age.

A difference in ethanol metabolism between premature and young adult rats was examined. Female SD rats, either 4wk or 12wk old, were injected with a single dose of ethanol (1.5g /kg) through jugular vein and the blood ethanol level was monitored for 300 min using a gas chromatographic method. Reduction of blood ethanol level per unit of time was less and the area under the blood concentration-time curve (AUC) was significantly greater in young adults compared to premature rats. Activity of hepatic alcohol dehydrogenase was not influenced by the age increase. Total cytochrome P-450, cytochrome $b_5$. or aminopyrine N-demethylation was not different between premature rats and young adult rats. However, p-nitrophenol hydroxylation and p-nitroanisole O-demethylation activities were significantly higher in premature rats. The relative liver weight was 45% greater in premature rats leading to an overall increase in ethanol metabolizing activity in these animals. The results indicate that the reduction in ethanol elimination in young adult rats appears to be mostly associated with the decrease in relative liver weight as the age of animals increases.

Background: Adolescent mothers may find the transition to motherhood to be overwhelming when compared to adult mothers. The adaptiveness of mother and infant feeding behaviors may greatly influence the quality of adolescent mothers' feeding interactions when compared to adult mothers. Purpose: To examine the adaptiveness of early maternal and infant feeding behavior between adolescent mothers and adult mothers. Method: In this secondary analysis, six adolescent mothers (< 20 years old) and six adult mothers were videotaped while feeding. The mothers were observed 3 times: when the infants were in the hospital, 1 month old, and 4 months old. The videotapes were coded using four scales of the Parent-Child Early Relational Assessment (PCERA). The two maternal scales were Positive Affective Involvement and Sensitivity/Responsiveness (PAISR) and Regulation of Affect and Behavior (RAB). The two infant scales were Infant Positive Affect, Communication, and Social Skills (IPACS) and Infant Regulation of Affect and Behavior (IRAB). The dyads were videotaped just before hospital discharge and at one and four months corrected age. The Wilcoxon signed-rank test was used to examine the difference in the PCERA between the two groups. Results: Adolescent mothers had a significantly lower score on the PAISR before hospital discharge (p-value 0.005) and at one month corrected age (p-value 0.008) than adult mothers. Adolescent mothers also had a significantly lower score on the RAB before hospital discharge, 1 and 4 months corrected age than adult mothers. There were no significant differences in IPACS and IRAB of infants of adolescent and adult mothers. Conclusion: Clinicians need to be aware of the differences in sensitivity that occur.

Background: Geladas (Theropithecus gelada), endemic to Ethiopia, are distributed closely related to the escarpments and gorge systems of the country, and large populations are found in the Simien Mountain National Park. This study was conducted in Eastern Tigray, Northern Ethiopia, from February 2018 to August 2019 in order to determine population size and composition of geladas. Total count method was used to estimate the population structure of geladas. Observations of the group of geladas based on body size and morphological characteristics were used to classify age and sex categories of the population. SPSS Version 20 was used to analyze the data. Chi-square test was used to compare sex ratio of geladas and population size among the counting sites between wet and dry seasons. Results: A total of 112 and 99 individual of geladas were counted during wet and dry seasons, respectively. Of the average gelada population recorded in this study, 11.4% were adult males, 30.3% were adult females, 12.8% were sub-adult males, 25.6% were sub-adult females, and 19.9% were unidentified juveniles. However, there was no statistically significant difference among the various age and sex groups of geladas counted during wet and dry season (χ² = 2.6, DF = 4, P > 0.05). Variations of group size along seasons were observed in this study. Sex ratio of adult male to adult female was 1:2.6 and 1:2.7 during the dry and wet seasons, respectively. Conclusion: Very small gelada population size was recorded in the current study. An average of 105.5 geladas was recorded during the study period. As this is the first report of gelada population in escarpments of Eastern Tigray, population trend of the geladas cannot decide based on the current study.

This study was to evaluate the body composition and bone mineral density according to aging in adult and investigated the relationship between various parameters such as body mass index(BMI), bone mineral density(BMD), bone mineral content(BMC), lean body mass(LBM), fat mass(FM) and the value obtained from dual energy X-ray absorptiometry(DEXA). The subjects were composed of healthy adult male and female who were $20^{\sim}73$ years old and they were divided three group according to age (A group : 20-39 yrs., B group : 40-59 yrs., C group : more than 60 yrs.). The conclusion derived from statistical analysis was as follows : 1. Bone mineral content and density were significantly affected by lean body mass(relatively, R=0.85 - 0.63). 2. There was significant difference among age groups in total bone mineral density. 3. There was significant difference among age groups in bone mineral content of male and female. 4. Lean body mass is diminished according to age, but there was not significant difference among age groups. 5. Fat mass of A group in male had the highest mass and followed by C group and B group. In female groups, fat mass of A group had the highest mass and followed by B group and C group. Abdominal fat mass is increased according to age. This result suggest that aging was closely relation with loss of muscle mass, bone mineral density and bone mineral content.
