No exception for the Kimbab Family. The portrait of the Indonesian Korean multicultural family, which was initially shared through YouTube channels as information for his family in other parts of the world, has become a practice of commodification that can be profitable. This research uses the Commodification Theory. Any audio-visual elements that make up a Kimbab Family show will be considered a sign. So, this study will use semiotics in carrying out the analysis. This research is a qualitative-descriptive study with a critical paradigm. This study found that Multicultural Families are families that must have high adaptive abilities, are fighters, focused, dynamic, and have a high potential to experience alienation. These things appear as a family life drama in the form of audio-visual that has a high potential for profit, whether realized or not by the Kimbab Family themselves. Researchers also found that: Multicultural families are a metamorphic formulation of the third culture, a culture that makes efforts to dominate other cultures, as something new but has marginalized other cultures. The multicultural family is a formulation of the conquest of one culture of another.","PeriodicalId":153802,"journal":{"name":"International Journal of Applied Science and Engineering Review","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123702312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, today it is experiencing a major economic and organizational crisis. The initial direct aid has been prioritized and standardized over time with a view to efficiency, making it counterproductive and exposing it to numerous criticisms. The question that arises is to what extent humanitarian aid contributes to the resilience of beneficiaries towards sustainable development. Indeed, based on the hypothesis that the intervention of humanitarians in the resolution of socio-economic problems of the vulnerable contributes to their resilience towards sustainable development, this study assesses the contribution of humanitarian aid not only in the resilience of vulnerable populations, but especially in the sustainability of their development.

The ∑PAHs concentrations recorded in T. fuscatus ranged from 0.10431/.μg/g d. wt in station (1) for the month of February, 2018 to 1.95775 μg/g d. wt for April, 2017 in station (1).

The result from PAHs analysis showed some level of bioaccumulation of 15 PAHs from below detection to appreciable limits in the tissues of the studied macrofauna. Seven low molecular weight PAHs and eight high molecular weight PAHs were identified in the tissues of T. fuscatus, indicating pyrogenic and petrogenic origin or source as a result of activities of crude oil bunkering and local refining in the study area. Fifteen of the identified PAHS are among the 16 listed PAHs by USEPA as priority pollutants in aquatic and terrestrial ecosystems and seven of those PAHs may cause cancer in humans. Although the PAHs level analysed in the macrofauna in Idema Creek Basin are below or within the limit permitted or allowed in sea food by WHO,EU/USEPA, but if the activities of illegal bunkering and local refining are allowed to continue unabated for years, it will pose a serious health risk to the inhabitants of Idema creek basin.","PeriodicalId":153802,"journal":{"name":"International Journal of Applied Science and Engineering Review","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132155565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their near proximity might expose people by ingesting, inhalation, and skin contact, which could have neurotoxic, mutagenic, and cancerous health effects. In Okitipupa, Ondo State, Nigeria, this investigation measured the level of PCBs in soil at five different sites. A GC paired with an ECD detector was used to evaluate the sample. Concentrated H2SO4 was used to clean the extracts. According to the study's findings, the average concentration of PCB congeners at the different sites was 5.364 g/kg, with a range of 0.150 to 13.30 g/kg. Recovery rates for specific PCB congeners ranged from 87% to 100%. The number of polychlorinated biphenyls (PCBs) in the soil was higher than the 0.050 mg/kg WHO acceptable limit. TetraPCB and triPCBs have a strong positive connection.
