  • 이 총설은 출하 전 절식에 관한 문헌을 요약 정리한 것이다. 도축 시 도체 오염 방지는 효과적인 절식 프로그램을 실시할 때만이 가능하다. 특별히 법으로 외견 또는 미생물적 오염을 규제하는 나라의 경우 절식은 매우 중요하다. 육계에 대한 절식은 도축 시 장 내용물로부터 도체 오염을 줄일 수 있어 이를 권장하고 있다. 대부분의 연구가 적정한 절식 시간, 도축, 가공의 효율성 유지 및 닭고기 안전성을 확보하기 위한 수단으로서의 절식 효과에 대해 초점을 두고 진행되었다. 실제적인 절식 프로그램은 생축생산 능력과 사육방식, 도축방법, 도축검사 및 도축관련 규정이 달라 나라마다 다르다는 점을 지적한다.

  • 전문대학의 재학생 충원율은 갈수록 문제가 되고 있다. 특히, 중도탈락률의 증가는 전문대학을 심각한 위기로 몰고 있어도 속수무책인 상황이다. 왜냐하면, 중도탈락 가능성이 높은 학생들이 입학한 상태에서는 기존의 어떠한 방법도 중도탈락을 방지하기란 어렵기 때문이다. 따라서 본 연구는 중도탈락을 미연에 방지할 수 있는 새로운 방안을 모색하는데 목적을 두었다. 이를 위해 D대학의 입학전형별 중도탈락 실태를 파악한 후, 그 결과를 입학전형 방법과 절차에 반영함으로써 중도탈락을 개선하는 방법을 제시하였다. 또한, 입학전형별로 대학생활 만족도와 중도 탈락률 간 비교를 통해 중도탈락률을 개선하는 방법도 제시하였다. 본 연구에서 제안한 방법은 전문대학의 중도탈락률을 개선하는데 유효하게 적용될 것으로 기대한다.

  • This study examined the relations among toddlers' temperament, maternal parenting, and toddlers' social withdrawal and aggression. One hundred and two mothers of two-year-old children (49 boys and 53 girls) completed questionnaires and Q-sort. Data were analyzed by correlation analyses and regression analyses. First, toddlers' pleasure was negatively related to social withdrawal, while social fearfulness was positively related to social withdrawal. Also, toddlers' activity level and anger proneness were positively related to aggression. Second, the encouragement of independence in maternal parenting was negatively linked to toddlers' social withdrawal, and maternal rejection was positively linked to toddlers' aggression. Third, toddlers' pleasure and interest/persistence were positively associated with mothers' encouragement of independence, and toddlers' activity level and anger proneness were positively associated with mothers' rejection. Finally, mothers' encouragement of independence acted as a mediator between toddlers' pleasure and social withdrawal. Also, toddlers' activity level and anger proneness influenced aggression through maternal rejection. These results indicate that toddlers' temperament and maternal parenting play crucial roles in the development of toddlers' maladaptive behaviors such as social withdrawal and aggression.

  • This study examined the effects of mothers' reactions toward children's negative emotion as well as mothers' emotional expressivity on children's social withdrawal. 206 children (103 boys, 103 girls; aged 4-5 years old) and their mothers participated in the study. Mothers reported their reactions to their child's negative emotion along with their expressivity. The teachers completed a rating scale to measure children's social withdrawal. The collected data was analyzed using descriptive statistics, Pearson's productive correlation coefficient, and hierarchical multiple regressions. The results showed a relation between mothers' distress reactions and punitive responses and children's social withdrawal. A mother's positive expressivity was negatively related to a child's social withdrawal. A hierarchical regression analysis indicated that the effects of mothers' punitive responses and minimization responses on children's withdrawal were moderated by a mother's positive expressivity. Mothers' punitive responses and minimization responses were positively associated with children's social withdrawal, especially for children who had the lowest level of mother's positive expressivity.

  • In this paper, the effects of parental neglect and abuse on school adjustment mediated by social withdrawal in adolescents were examined using a sample of 2,163 second grade middle school students(1,096 boys and 1,067 girls) from the Korean Child and Youth Panel Survey(KCYPS) data set. All research variables were measured using self-reported questionnaires. They were analyzed by means of Structural Equation Modeling. The results indicated that parents' abuse had no direct effect, but there was an indirect effect on adolescents' school adjustment mediated by adolescents' social withdrawal. Parental neglect had a direct effect on adolescents' school adjustment and also had an indirect effect on adolescents' school adjustment mediated by social withdrawal. The results indicate that parental neglect is a more significant contributor than adolescents' social withdrawal on adolescents' school adjustment. The results of this study show that parenting attitude, more specifically parental neglect, tend to be more important factors on school adjustment compared to adolescents' psychological problems, such as social withdrawal in adolescence. Taken together, these findings suggest that interventions aimed at improving parental neglect and adolescents' social withdrawal need to be emphasized if adolescents are to better adjust to school life.

  • This study investigated the moderating effects of the number of friends and quality of friendship on the associations between withdrawal and loneliness as well as withdrawal and social anxiety. The subjects were 678 of fifth and sixth grade primary school children recruited from a public school in Bucheon city. A peer nomination inventory was used to assess withdrawal. Children were given a classroom roster and asked to nominate three classmates who fit each description. Children reported the quality of their friendships using the Friendship Quality Scale. Each child was asked to indicate his or her one best friend and rate how accurately a sentence describe done of their best friends on the scale. In addition, children completed questionnaires to assess the loneliness and social anxiety. The results revealed that the association between withdrawal and loneliness was not significant for children who had the large number of friends and high quality friendship. The association between withdrawal and social anxiety was stronger for the children who had the lower levels of friendship quality. However, there was no moderating effect of the number of friends on the association between withdrawal and social anxiety. These results imply that the large number of friends and high quality friendships could be protective factors for children who are withdrawn.

  • This study examines the effect of satisfaction with adolescent extracurricular activities on social withdrawal with a focus on the mediating effect of self-esteem and sense of community. We used data from the 3rd wave (2012) of the Korean Children and Youth Panel Survey (KCYPS) collected by the National Youth Policy Institute for path analysis. Participants were 1,139 first year middle school students who participated in adolescent extracurricular activities. First, the degree of satisfaction with the adolescent extracurricular activities had an indirect effect on social withdrawal via self-esteem. Second, satisfaction with the adolescent extracurricular activities had an indirect effect on social withdrawal via a sense of community. Lastly, satisfaction with adolescent extracurricular activities had an indirect effect on social withdrawal via self-esteem and a sense of community. The research findings indicate that the level of social withdrawal is less when adolescents are satisfied with adolescent extracurricular activities and have a high level of self-esteem and sense of community. The results demonstrate that a satisfactory level of adolescent extracurricular activity would help adolescents decrease their social withdrawal by increasing the level of self-esteem and sense of community.

  • This paper reports a method to evaluate the residual strength of insect-damaged radiata pine lumber, such as the screw withdrawal strength as a semi-destructive method and a compression parallel to the grain test to assess the density changes after exposure to outdoor conditions. The screw withdrawal strength test was used as a semi-destructive method to estimate the residual density of decayed lumber. A compression parallel to the grain test was applied to evaluate the residual density. Three variables, such as the screw withdrawal strength, compression parallel to the grain, and residual density, were analyzed statistically to evaluate their relationships. The relationship between the residual density and screw withdrawal strength showed a good correlation, in which the screw withdrawal strength decreased with decreasing density. The other relationship between the residual density and compression parallel to the grain was also positively correlated; the compression parallel to the grain strength decreased with decreasing density. Finally, the correlation between the three variables was statistically significant, and the mutual correlation coefficients showed a strong correlation between the three variables. Hence, these variables are closely correlated. The test results showed that the screw withdrawal strength could be used as a semi-destructive method for an in situ estimation of an existing wood structure. Moreover, the method might approximate the residual density and compression parallel to the grain if supplemented with additional data.

  • Purpose: This descriptive study investigated the effects of nurses' knowledge of withdrawal of life-sustaining treatment, death anxiety, and perceptions of hospice care on their attitudes toward withdrawal of life-sustaining treatment. Methods: Data were collected from 262 nurses at tertiary hospitals, general hospitals, or primary hospitals in Busan, Korea, and statistically analyzed using the t-test, analysis of variance, the Scheffé test, Pearson correlation coefficients, and hierarchical regression analysis. Results: The participants' scores were 3.68±0.45 (out of 5) for attitudes toward withdrawal of life-sustaining treatment, 0.65±0.15 (out of 1) for knowledge of withdrawal of life-sustaining treatment, 2.61±0.26 (out of 4) for death anxiety, and 4.06±0.43 (out of 5) for perceptions of hospice care. Furthermore, knowledge of withdrawal of life-sustaining treatment and perceptions of hospice care showed positive correlations with attitudes toward withdrawal of life-sustaining treatment, while death anxiety showed a negative correlation. The most significant factors influencing attitudes toward withdrawal of life-sustaining treatment were perceptions of hospice care, followed by having experienced caring for patients who withdrew life-sustaining treatment, death anxiety, having a spouse, and ethical values, and the overall explanatory power was 43.0%. Conclusion: This study showed that perceptions of hospice were an important factor influencing nurses' attitudes toward withdrawal of life-sustaining treatment. Therefore, it is necessary to develop and validate educational intervention programs that can improve perceptions of hospice care.
