This study was performed to examine the quality and antioxidant activity of pork ham with various levels of black garlic extracts. Pork ham manufactured from black garlic extracts with 15 brix (1% (H1), 1.5% (H2), 2% (H3)) and 30 brix (0.2% (H4), 0.5% (H5), 1% (H6)) were stored for 28 days at 8±1℃ and analyzed with an interval of 7 days. In the sensory evaluation, the garlic odor was increased as the garlic extract adding level larger, whereas color, flavor, juiciness, texture and acceptability were not showed significant differences. The pH values of pork products were increased as the level of black garlic extracts increased. The shear force value of groups (H4~H6) with the addition of 30 brix extracts addition were significantly higher than those groups with 15 brix extracts addition (H1~H3) throughout the storage period. Furthermore, the TBARS (thiobarbutric acid reactive substance) content of the pork ham containing various levels of black garlic extract were lower than that of the control group as storage period increased. Thus, black garlic extracts have a potential application for the pork products to inhibit of lipid oxidation.

성윤희(Sung, Yun Hee),양승미(Yang, Seung Mi) 사회복지법제학회 2021 사회복지법제연구 Vol.12 No.2

「제2차 아동정책 기본계획(`20~`24)」은 아동권리·아동중심 원칙을 확산하기 위한 실행기반 중 하나로 가칭 아동기본법을 제정하여 아동 권리 실현을 위한 법적 환경 조성을 구상하였다. UN아동권리협약의 당사국으로, 각각의 개별법을 통하여 아동의 권리를 보호하고 있는 현행법체계에서 모든 아동을 대상으로 하는 종합적인 법률을 제정하려는 것은 상당히 의미 있는 시도이다. 이에, 본 연구에서는 아동 관련 주요 법률 현황을 검토하였으며, 향후, 입법 시 고려할 사항을 제시하였다. 그 내용을 요약하면 다음과 같다. 첫째, 아동 중심 권익실현체계 정립 및 이를 위한 관련 데이터 구조화 등이 중요하다. 즉, 아동 중심의 권익 실현 및 기본적 권리 강화를 위하여 아동에 대한 세밀한 이해를 전제로 한 다양한 수요공급 현황분석이 뒷받침되어야 한다. 둘째, 아동이 개인으로서, 주체적이고 능동적인 권리주체임을 이해하고, 공급자적 규정 또한 최대한 아동을 중심으로 구성되어야 하며, 아동 권리 실현을 위한 수요자 중심의 법안 마련을 지향한다. 셋째, 현행 법체계에서 아동기본법의 역할을 정립하고, 관련 법체계와의 정합성을 고려하는 등 정치한 법 연결망을 통하여, 기본법의 구속력 확대·강화를 도모할 필요가 있다. 넷째, 장기적으로는 체계적이고 융합적인 아동법제를 지향함으로써, 향후 종합법적 아동법전으로 발전해가기를 기대한다. 아동기본법 제정은 아동에 대한 세밀한 이해를 전제로, 법률 전체의 균형과 조화를 고려한 신중한 작업이어야 한다. 이러한 논의가 진정한 아동 중심의 입법 시스템 구축에 일조가 되기를 바란다. “2nd master plan for child policies” has designed the legal environment to realize the children’s rights by enacting the “Framework Act on Children” as one of the implementation Fundamental for expanding the children’s rights and children-centered principle. In Korea which is a party to Convention on the Rights of the Child, it is a very significant try to enact the comprehensive laws for all children in the existing legal system under which the children’s rights have been protected through each law of the system. Therefore, this study reviews the main children’s laws and suggests the considerations for future enactment. The considerations can be summarized as follows. First, it is critical to establish the children centered rights realization system and structuralize the related data for this. It means that, for the realization of the children centered rights and strengthening of the Fundamental Rights, the analysis of various demands and supplies shall be made based on the deep understanding of children. Second, based on the understanding that the children shall be the subjective and active rights holders as individuals, the regulation shall be organized based on the children to the maximum and the children centered legal drafts shall be prepared for the realization of children rights. Third, under the current legal system, the role of “Framework Act on Children” shall be established and the consistency with the related laws shall be considered, thus trying to expand and the strengthening the binding power of the Framework Acts through the well-organized legal network. Fourth, it shall pursue for the systematic and integral restructuring of children’s law system and play the roles of comprehensive children’s law as an integral law. The enactment of “Framework Act on Children”shall be the sincere work considering the balance and harmony in the total legal system based on the full understanding of the children. It is expected that the discussion on this topic contributes to the construction of true children-centered legal system.

Objective : This study examined the socioeconomic differentials for the health and health related behaviors among South Korean middle school students. Methods : A nationwide cross-sectional interview survey of 3,449 middle school second-grade students and their parents was conducted using a stratified multi-stage cluster sampling method. The response rate was 93.3%. The socioeconomic position indicators were based on self-reported information from the students and their parents: parental education, father's occupational class, monthly family income, out-of-pocket expenditure for education, housing ownership, educational expectations, educational performance and the perceived economic hardships. The outcome variables that were measured were also based on the self-reported information from the students. The health measures included self-rated health conditions, psychological or mental problems, the feelings of loneliness at school, the overall satisfaction of life and the perceived level of stress. The health related behaviors included were smoking, alcohol drinking, sexual intercourse, violence, bullying and verbal and physical abuse by parents. Results : Socioeconomic differences for the health and health related behaviors were found among the eighth grade boys and girls of South Korea. However, the pattern varied with gender, the socioeconomic position indicators and the outcome measures. The prevalence rates of the overall dissatisfaction with life for both genders differed according to most of the eight socioeconomic position indicators. All the health measures were significantly different according to the perceived economic hardship. However, the socioeconomic differences in the self-rated health conditions and the psychosocial or mental problems were not clear. The students having higher socioeconomic position tended to be a perpetrator of bullying while those students with lower socioeconomic position were more likely to be a victim. Conclusions : The perceived economic hardships predicted the health status among the eighth graders of South Korea. The overall satisfaction of life was associated with the socioeconomic position indicators. Further research efforts are needed to explore the mechanisms on how and why the socioeconomic position affects the health and health related behaviors in this age group.
