The data were consisted of 1,262 records for carcass traits observed at Hanwoo steers from 1998 to 2001 at Namwon and Deakwanryung branch of National Livestock Research Institute, Rural Development Administration. Pedigrees of young bulls were traced back to search for magnifying inbreeding. Genetic parameters for carcass traits with Gibbs sampling in a threshold animal model were compared to estimates with REML algorithm in linear model. As the results, most of bulls were not inbred and sire pedigree group was non-inbred population. However, most of the bulls fell in some relationship with each other. Heritability estimates as fully posterior means by Gibbs samplers in threshold model were higher than those by REML in linear model. Furthermore, these estimates in threshold model using GS showed higher estimates than estimates using tested young bulls in previous study and same model. Heritability estimate by GS for marbling score was 0.74 and genetic correlation estimate between marbling score and body weight at slaughter was –0.44. Further study for correlation of breeding values between REML algorithm in linear model and Gibbs sampling algorithm in threshold model was needed.

The purpose of this study is to examine the necessity of providing new perspectives by conveying the various psychological changes and realities experienced by victims of incest sexual violence after the incident, And it is meaningful to understand and record it through. The results of the analysis through the phenomenological methodology are as follows: First, participants were disturbed by the emotional neglect of their parents and forced violence, threats, and silence by their family members, resulting in disbelief in interpersonal relationships and low self-esteem and suffered constant difficulties in daily life. Second, the suffering and aftereffects of sexual violence experienced the conflict of roles by repeating the real maladjustment and social activity avoidance as the fear of being informed about the event, the negative thought about oneself, and the difficulty of interpersonal relationship. Third, the aftereffects of incest sexual violence in childhood·adolescence were found to be extreme with regard to PTSD. The PTSD experience has become a factor that forces participants to rely on substances, such as psychiatric medications and alcohol, and further avoids external activities with hallucinations and delusions. Fourth, the change through the adaptation process is a new perspective on life, facing and separating the events. During the adaptation program, they tried to express their words and feelings that they could not express because of the past hurts, to set goals for living their life, and to move forward. The experience of overcoming reality has enhanced participants' confidence in self-esteem, self-efficacy, and healthy self-control ability. In this study, it is meaningful to suggest a model in which the incest sexual violence trauma is reexperienced through the new daily crisis and the new adaptation process is repeated for each process.

물과 인간은 떼려야 뗄 수 없는 관계이다. 때로는 물 때문에 번성하고, 때로는 물 때문에 파멸한다. 그렇기 때문에 물에 대한 남다른 의례와 신화들이 발생한다. 인류의 문명이 강을 중심으로 발생한 것도 물이 지닌 가치를 단적으로 말해준다. 물에 얽힌 이야기, 그 첫 장을 여는 데 아득히 먼 옛날에 일어났던 불행한 물의 신화를 이야기 하지 않을 수 없다.

This study was carried out to investigate the time-trends of genetic parameters of the dosed flock population which selected for improving egg production. Data for two layer pure lines, Line-W (Single Comb White Leghorn) and Line-B (brown layer) which have been maintained at the Mani Breeding Farm were collected from 1980 to 1985 during 5 generations. The effective number of parents per generation ranged from 148 to 366 in Line-W and 85 to 355 in Line-B, and the cumulative expected inbreeding coefficients during 5 generations of selection were 15％ and 1.6％. So inbreeding could not be considered a critical factor on estimating the genetic parameters, heritabilities and genetic correlations Heritabilities of EN 300 and EN 400, primary two selected traits were significantly decreased during 5 generations but the estimates of the other 03its not showed the consistent decreasing pattern significantly. No time trends of probable consequence were evident in the genetic correlation coefficients of the traits studied. The reason for that situation was attributed to the fact that selection was conducted for multiple objectives and the relative importance of selection for the studied traits were not consistent by generations.

A two-year-old, female English bulldog was referred for breeding by artificial insemination with frozen semen of male English bulldog, a litter of female bulldog's grandfather. Intrauterine artificial insemination was done two days after the ovulation day. Sperm was evaluated after thawing by computer assisted sperm analyzer, and its motility was 89.8% with normal shape. Pregnancy bearing eight fetuses was diagnosed by ultrasonography and radiography. Cesarean section was performed sixty days after the artificial insemination. Eight pups were delivered with safe, but the entire pup had abnormalities including severe bow-legged malformations, cleft lip, cleft palate, and enlarged cranial part.

This study set out to investigate the adaptation process and experiential structure of those children who went through sexual abuse by looking into their inner worlds in order to understand what kind of meaning sexual abuse had on them. For that, the investigator conducted in-depth interviews with 13 children aged 8~16 who lived at the shelter after experiencing sexual abuse. The methodology of Grounded Theory by Strauss and Corbin(1990) was used to analyze raw data. The analysis results indicate that the core theme of the adaptation process among the children living at the shelter after sexually abused by kin and kith was "hoping to appear the same as others." According to the results, the core phenomenon was "blaming the victims." The causal conditions include "broken families," "antihuman sexual abuse," "making sexual abuse a public issue," and "the trap of the family." The contextual conditions include "the chain named family," "family as the last fortress" and "structural enforcement of silence." The intervening strategies was "dual emotions toward the shelter." The action/interaction strategies include "aftermath of violence" and "trying to escape." The consequences were "preparation for the future" and "uncertain future." The identified stages include the confusion, keeping the secret, leaking the secret to others, intervention by others, social support and challenge and adjustment stage. The three identified types were "withdrawal and avoidance," "settling down in reality" and "overcoming and challenging." Based on the analysis results, discussions were made about the social welfare plans and intervention strategies in the conclusion.
