The purpose of this experimental research is to suggest a base data to utilize the fine sand of Nakdong-River actively as an alternative aggregate for concrete. For this purpose, after the typical fine sand samples were collected at the mid stream and down stream of main stream of Nakdong-River, the physical properties of them and the mix characteristics of concrete using those were estimated. As a result, it was observed from the test result that mix characteristics between concrete using fine sand and concrete using well-graded reference sand made little differences since unit water content and unit cement content of concrete using fine sand increased only a little than those of concrete using reference sand for specified compressive strength.

Jehovah's Witnesses do not accept blood transfusions, because of their particular interpretation of the Old and New Testaments. When people with such religious convictions are in need of medical care, their faith and belief may become an obstacle for proper treatment, and pose legal, ethical, and medical challenges for the health care providers. We report two inherited metabolic disorder cases in South Korea where the infants died whilst under medical care because of parental refusal of blood transfusions for religious reasons. Case 1 had methylmalonic acidemia, Down syndrome and associated congenital cardiac anomalies requiring surgery. Case 2 had anemia and methylmalonic acidemia requiring dialysis to treat hyperammonemia and metabolic acidosis. For effective medical management, they needed life-saving blood transfusions. As a part of alternative treatment, Erythropoietin was administered in both cases. As a result, two babies died from their extremely low hemoglobin and hematocrit. The hemoglobin concentrations below 2.7 g/dL without cardiac problem and 5.4 g/dL with cardiac anomaly complicated by pulmonary hypertension are considered life-threatening hemoglobin threshold. The medical professional must respect and accommodate religious beliefs of the patients who can make informed decisions. However, when parents or legal guardians oppose medical treatment of their babies and incompetent care receivers on cultural and religious grounds, the duty to assist and save persons exposed to serious danger, particularly life-threatening events must come first.

The present remodeling makes almost no difference from rebuilding as all the building materials are removed remaining frame structure only. And, in case of vertical extension of building, higher construction cost and safety problem occur. The Ministry of Land, Transport and Maritime Affairs, therefore, recommends customized remodeling that can be made in light of the resident' needs such as parking lot, elevator, bathroom, and room for the alternative of remodeling of vertical extension of building. The purpose of this study is to present real data that can be referred to the constructor's decision making before starting the remodeling, by investigating and analyzing the weight and importance between evaluation factors for customized remodeling at the completed time of remodeling. Accordingly, the factors were divided into environmental factor, social factor, and economical factor, and the survey was performed for the residents living in remodeling houses. In addition, for the professionals, AHP (Analytic Hierarchy Process) has been carried out for the priority in the customized remodeling. For environmental factor, the level of importance made difference from that before remodeling, except parking level. For social factor, every item, including psychological satisfaction and community satisfaction, made difference. For economical factor, the recognition level of importance in rent made difference, except sale price of the factor for price satisfaction. In case of the factor for cost satisfaction, it was checked that construction cost and administration cost both could be considered important. As a result of AHP, the most importantly emphasized item was construction cost, and sale price, administration cost, residence structure, and parking lot were followed by priority in order. This study could contribute to reliably settle down customized remodeling by giving reasonable and substantial help from the analysis of the differences in the customized remodeling items before/after the remodeling.

This study presents methods and alternative examples for fashion brands to effectively use video-based communication channels to form brand identity that analyzes the definition, status and type of YouTube channel fashion films as well as enables the ability to derive brand identity characteristics. Literature studies focused on Christian Dior's official website and related previous studies. The temporal range of the case studies was from October 7, 2010, the date when the first fashion film was uploaded to current Christian Dior YouTube to July 17, 2020 (the survey date), and there are a total of 550 subjects for quantitative analysis. The succession of the couture spirit means that Christian Dior's craftsmanship was created and passed down by Musée Christian Dior to act as a contemporary key element of brand identity. The iconic expression of femininity is Dior's core design philosophy that began when the woman image of a new era was presented through a new look, and Dior's femininity means a woman that reflects the character of the times as is interpreted as her own personality from the perspective of modernism through the creative directors of future generations. The brand's core identity code 'Miss Dior' expresses the brand's vision and eternity through perfume as well as targets Z generation male consumers through an emotional approach based on forms that used emotional images such as movie-type films.

Pseudomonas aeruginosa (P. aeruginosa), Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) are typical opportunistic pathogens. Moreover, these bacteria are known to possess multidrug-resistant (MDR) properties. This study investigates the antimicrobial activity of six fermented products, which have varying efficacies against P. aeruginosa, E. coli, and S. aureus. To identify novel candidate genes, differential expression analysis was performed using an annealing control primer. In the disk diffusion method, Fig vinegar (FV) and Diospyros kaki Thunb vinegar (DTV) showed the greatest increase in inhibition compared to other fermented products, whereas fermented Korean traditional nature herb (FKTNH) had no antibacterial effect. This study identified down-regulation of Escherichia coli O157:H7 ompW gene for outer membrane protein W, whereas gene for synthetic construct Lao1 gene for L-amino acid oxidase were up-regulated in E. coli treated with 5% FV. Consuming fermented vinegar helps prevent bacterial infections. Especially, FV and DTV are potentially useful alternative natural products for multidrug resistance. Furthermore, both are expected to be used as effective natural antimicrobial agents, such as disinfectants.

Using antibiotics as growth promoter has been banned in poultry feed industry, thus various researchers try to seek an alternative to replace the growth-promoting antibiotics. In this study, we aimed to evaluate the growth performance via intestinal nutrient utilization and cecal microbial composition of broiler after dietary supplementation with most commonly using antibiotics, zinc bacitracin, and sophorolipid. A total of 180 1-day-old chicks were randomly assigned, and dietary treatment was as follow: CON, basal diet; ZB, 100 ppm of zinc bacitracin supplemented diet; and SPL, 250 ppm of sophorolipid supplemented diet. Their growth performance was evaluated and the samples of blood, small intestine, and ileal and cecal digesta were collected for biochemical, histological, and genomic analyses. The body weight and average daily gain of 7-day-old chicks were higher in ZB and those in overall experimental period were improved by ZB and SPL supplementation (p < 0.05). Their intestinal characteristics were not affected by dietary treatments in duodenum and ileum. Nonetheless, villus height was increased by SPL supplementation in jejunum (p < 0.05). Moreover, dietary SPL supplementation could down-regulate the expression level of pro-inflammatory cytokine, IL-1β (p < 0.05). mRNA levels of lipid and protein transporters did not differ among the treatments, however, relative expression levels of carbohydrate transporters, GLUT2 and SGLT1 were increased in broiler chicken's jejumum fed zinc bacitracin and sophorolipid supplemented diets (p < 0.05). Dietary zinc bacitracin supplementation could increase the population of Firmicutes in phylum level, and the portion of Turiciacter in genus level. On the other hands, the portion of Faecalibacterium was increased by dietary SPL supplementation compared to the other treatments. Our findings suggest that SPL supplementation improves growth performance through enhanced carbohydrate utilization capacity via improvement of gut morphological status and modulation of the cecal microbial population of broilers.

In March 2020, the National Assembly revised the Framework Act on Cooperatives, allowing a federation of heterogeneous cooperatives, and in October 2020, the Daegu Gyeongbuk Federation of Local Food Cooperatives was launched as the first federation of heterogeneous cooperatives in the country. The local food movement, which has been promoted upward in the local community as an alternative to the existing global food system, seems to be being activated by the government's food plan policy, but critics say that the government's policy goals are not fully achieved due to the top-down policy promotion and lack of communication. In response, this study first examines the role and significance of the local food federation of heterogeneous cooperatives in solving the problems raised in the process of establishing a food plan. In addition, the current status of the federation was investigated for the successful settlement and development of the Daegu Gyeongbuk Federation of Local Food Cooperatives. A survey of affiliated cooperatives, focus group interviews with managers and experts and related literature surveys were conducted. Based on this, the direction of activities was presented, such as the role of an intermediary in Daegu and Gyeongbuk and the role of an intermediary in the public and private sectors etc. In addition, six joint project tasks were specifically presented, including an integrated information sharing system & a logistics network, a planned production system & a joint processing center, an online sales system & a co-marketing promotion, a joint education system, a management of direct stores & restaurants, a sustainable public-private cooperation system etc.

The objective of this study was to investigate the necessity of rural tourism education in the Korea National Agricultural College and suggest the educational plan. Recently, the Korean government proposes the rural tourism as an alternative plan for solving the problems of agriculture and rural community that experience difficulty by the opening of agricultural market and the falling price, etc. As result of investigation of cases of OECD nations and the growth rate of tourism market in Korea, it has been determined that the demand of rural tourism was sufficient. The Ministry of Agriculture & Forestry makes a goal of attracting the yearly 150million tourists by 2013 to the rural communities. Rural tourism can be new income source in the rural communities in Korea. It is important to develop the resources in the rural amenity and promote the tourism leader group with it that will be applicable in the field in order that this rural tourism may take its place as main source of income. As a result of research, on the characteristics of the Korea National Agricultural College that the demand of manpower about the rural tourism and the most of students settled down on the rural community after their graduation, it has been determined that the education for rural tourism leaders in the Korea National Agricultural College would authenticate the validity. Also, it suggested the educational plan by the curriculum for the education for the rural tourism leaders, and suggested the necessity of the establishment of the department of rural tourism. The establishment of the department of rural tourism in the Korea National Agricultural College should be investigated and determined carefully through the relations with the other departments and the process of collecting the public opinions within and outside schools, etc.

Bring this analysis down to people-centered development perspective and looking through democratization in the Philippines, Thailand and Indonesia, we find similarities and differences among them related with the intensity of conflicts between development and human rights in the process of democratization in line with global transformation. Civil society in the Philippines criticized the developmental path in the Philippines which failed to implement land reform and eradication of poverty under the transition from 'patrimonial oligarchy' to democracy. In Thailand the coalition of military and the royalists had consolidated its power since Sarit military regime, which later paved the way 'hybrid oligarchy' era. Most Thai civil society organizations has regarded their developmental experience rather as 'maldevelopment' which disregarded economic and social rights. It has been especially believed by Thai localists that the stimulation of local markets and the building of autonomic community society will form the alternative economy without going against the conservative banner of nation, religion and king. Thaksin as a populist successfully took advantage of Thai localist ethos in favour of taking the seat of power. He projected himself as a modernizer focused on economic growth and cleaner politics. However Thaksin's procedural legitimacy was overthrown by counterattacking from military-royalist alliance, pretexting that Thaksin caused internal conflicts and lacked morality. Soeharto's New Order regime which can be called 'administrative oligarchy' had an antipathy towards notions of economic and social rights as well as civil and political rights. In spite of the fact that the fall of Soeharto opened the political space for democratic civil society organizations which had long struggled with development aggression and human rights abuses, there have been continuously a strong political and military reaction against human rights activists, NGOs and ethnic minorities such as Aceh and Papua. Nevertheless, Indonesian democracy is more promising than Philippine's and Thai democracy in terms of comparatively less pre-modern legacies.

Nontraditional or alternative medicine is becoming an increasingly attractive approach for the treatment of various inflammatory disorders and cancers. Curcumin is the major constitute of turmoric powder extracted from the rhizomes of the plant Curcuma longa. Resveratrol is a phytoalexin present in grapes and a variety of medicinal plants. In this report, We investigated the effect of curcumin and resveratrol on regulatory protein of cell cycle, induction of apoptosis and MMP activity. Treatment with 75 M curcumin for 24 hrs produced morphological changing in HN-4 cells. Curcumin and resveratrol inhibited the cellular growth in HN-4 cells. Inhibition of cell growth was associated with down-regulation of cell cycle regulatory proteins. Curcumin-induced caspase-3 activation and Bax degradation were dose-dependent with a maximal effect at a concentration of 100 M. The elevated caspase-3 activity in curcumin treated HN-4 cells are correlated with down-regulation of survivin and cIAP1, but not cIAP2. Curcumin induced a dose-dependent increase of cytochrome c in the cytosol. Curcumin induced-apoptosis was mediated through the release of cytochrome c. In addition, curcumin-induced apoptosis was caused by the generation of reactive oxygen species, which was prevented by antioxidant N-acetyl-cysteine (NAC). Cotreatment with NAC markedly prevented cytochrome c release, Bax cleavage and cell death. Also resveratrol-induced apoptosis was preceded by down-regulation of the anti-apoptotic Bcl-2, cIAP1, and caspase-3 activity. However, resveratrol-induced apoptosis was not prevented by antioxidant NAC. In addition, HN-4 cells release basal levels of MMP2 when cultured in serum-free medium. Treatment of the cells with various concentrations of PMA for 24 hr induced the expression and secretion of latent MMP9 as determined by gelatin zymography. HN-4 cells were treated with various concentrations of curcumin and resveratrol in the presence of 75 nM PMA, and MMP2 and 9 activities were inhibited by curcumin and resveratrol. These findings have implications for developing curcumin-based anticancer and anti-inflammation therapies.
