본 논문은 남미공동시장의 역내 비대칭성의 특징과 해소를 위한 지역개발협력 중 FOCEM의 사례를 다루고 있다. 서던콘지역 국가들은 남미공동 시장의 형성을 통해 역내 균등 성장을 기대하였다. 그러나 출범 초기부터 구조적 비대칭성을 지니고 있었던 남미공동시장은 통합이 진척됨에 따라 정책적 비대칭성 또한 노출하였다. 이러한 구조적·정책적 비대칭성은 기본적으로 역내 '특수지위'를 점하고 있는 브라질의 남미공동시장에 대한 압도적 영향 때문이다. 이러한 역내 비대칭성에 대해 파라과이는 최약소국으로서 차별적 대우를, 우루과이는 역내 시장자유화의 동등한 적용을 원하며 아르헨티나는 글로벌가치사슬에 기반한 역내 생산통합을 강조한다. 비대칭 성문제에서 있어 일종의 청원자의 위치에 있는 파라과이, 우루과이, 아르헨티나에 비해 브라질은 민족적 이해에 따라 여러 선택을 할 수 있다. 이러한 상황 하에서 남미공동시장은 역내 비대칭성 해소를 위해 일종의 지역재분배기제인 FOCEM(구조조정수렴기금)을 설립하였다. FOCEM은 파라과이의 예에서 보듯이 일부 개발지표의 개선을 통해 개발격차해소를 가져왔지만 여전히 재정상의 한계와 시행력 부족 등이 문제로 남아 있다. 지역재분배 기제의 활성화와 비대칭성 해소를 위한 정책 조정을 위해서는 초국적 거버넌스를 통한 적극적인 정책이 요구되지만 이는 일정 정도의 주권의 위임이 요청하기에 회원국들은 이에 대해 주저하는 상황이다. 남미공동시장의 역내 비대칭성에 대한 해소 노력에도 불구하고 역내 비대칭성과 개발격차는 여전히 문제로 남아 있으며 또한 개별 국가 내 불균등 또한 난제로 남아 있다.

This study was carried out to obtain the information on the antioxidant activity of Phyllanthus. We compared and analyzed three indigenous collections of Phyllanthus: species from Korea, Brazil and Paraguay. Total phenolic acid contents were $1.93{\pm}0.015$ mg/mL in KCS (Korean Collection Species), $1.65{\pm}0.003$ mg/mL in PCS (Paraguay Collection Species) and $1.49{\pm}0.003$ mg/mL in BCS(Brazil Collection Species). In both DPPH radical scavenging activities and SOD-liked activities, KCS was the highest ($67.25{\pm}0.03%,\;78.38{\pm}1.17%$). KCS were also the highest in hydroxyl radical scavenging activities ($95.80{\pm}0.17%$). It turned out that there was no meaningful difference between BCS ($81.64{\pm}0.23%$) and PCS ($81.54{\pm}0.04%$). As for hydrogen radical scavenging activities, there was no statistically meaningful difference between KCS ($36.44{\pm}0.24%$) and BCS ($36.31{\pm}0.33%$) and it was the lowest in PCS ($33.72{\pm}0.15%$). Our results showed that KCS excelled the others not only in antioxidant activity but also in other beneficial effects. This encouraging results may be potentially useful in developing Phyllanthus urinaria L. variety which contains lots of functional elements such as total phenolic acid.

Two new species of oribatid mites, Dicastribates tenuisetosus sp. nov, and Liacarus unjangensis sp. nov. are described from Korea. Dicastribates tenuisetosus sp. nov. is easily distinguishable from a single known species, D. heterotrichus (Mahunka, 1984) from Paraguay by the presence of 14 pairs of distallv attenuate notogastral setae, the smooth rostral and lamellar setae, the relatively short and distally attenuating interlamellar setae, the relatively short sensilli with distinctly clavated head, and presence of two and six setae on epimeral region III and genital plate. Liacarus unjangensis sp. nov. can be easily distinguished from most other known species by the very wide lamellae which cover dorsally whole prodorsum, the presence of equal sized inner and outer teeth of lamellar cusps and the minute rostral, lamellar and interlamellar setae.

Nearly 50 highly sweet substances have been isolated and structurally characterized from green plants, and such compounds comprise mainly various types of terpenoids, flavonoids, and proteins. Among the sweet substances that have been studied as constituents of North and South American medicinal plants are the sesquiterpene, hernandulcin, the triterpene glycosides, abrusosides A-D, the steroidal saponins, polypodosides A and B, and the dihydroflavonol, dihydroquercetin-3-acetate. In addition, safety studies have been performed on the potently sweet substance, stevioside, from the 'sweet herb of Paraguay' (Stevia rebaudiana), a compound now produced on a commercial scale.

본 연구는 브라질의 서부에 있는 Mato Grosso do Sul 주의 Jangada 농장과 Jamaica 농장에 유칼리나무 식재계획(植栽計劃)을 원활히 추진하기 위해 인공위성사진을 이용하여 식생분류(植生分類) 및 토지이용구분(土地利用區分), 경사도(傾斜度) 및 영구자연보존지역(永久自然保存地域) 등을 분석한 결과이다. Mato Grosso do Sul 주의 서쪽에 위치하는 이 지역은 볼리비아와 파라과이의 국경근처에 있기 때문에 지정학적(地政學的)으로 매우 중요하다. 또한 물품수출이 파라과이강을 통해서 아르헨티나의 수도인 부에노스아이레스 까지 도달될 수 있고 브라질의 남동지역과 안데스산맥에 연한 국가들을 연결하는 국도(國道)와 철도(鐵道)가 존재한다. 농장의 산림(山林) 피복지역(被服地域)의 일차해석을 위한 기초로서 Radambrasil프로젝트 SF-21 Campo Grande로부터 얻은 식생지도가 사용되었고, 그 이후에 현장조사(現場調査)가 수행되었다. 최초의 이미지해석이 이루어진 후에 사용급과 토지점유에 대한 개념정의가 이루어 졌으며 스펙트럼분류가 행해졌다. Jangada 농장과 Jamaica 농장에 있어서 산림지역 Savanna와 초원지역 Savanna가 전체 총면적의 68% 정도를 차지하고 있다. 현재로서 만족한 연구결과에도 불구하고 이미 이루어진 평가결과(評價結果)에 기초하여 프로젝트 발전을 위한 수정(修正)과 보완(補完)이 요구된다. 특히 토양(土壤)과 지형(地形)을 포함해서 환경인가에 대한 상세한 분석이 병행되어야 할 것이다.

Postweaning performances of steer from 11 to 18 months of age under intensive feedlot condition were examined in Brahman and Santa Gertudis cattle breeds which have been established in Paraguay. Fitting of growth data in each breed to an empirical growth model with non-linear least square analysis resulted in the following age(t; months) - weight(w; kg) function made out each breed: w=638.26($1-2.341e^{-0.010965t}$) for Brahman and w=716.38($1-2.365e^{-0.10741t}$) for Santa Gertrudis. The estimated mature size of Brahman steers(638 kg) was 11% lower than that of Santa Gertrudis steers(716 kg). However, slightly larger k value (rate of maturing) of Brahman steer in the mechanistic model suggested relatively earlier maturing tendency in the breed. No significant differences in dressing percentage (Brahman, 59.3%; Santa Gertrudis, 58.8%) of chilled carcass weight to live-weight were observed between breed.

MERCOSUR (Southern Cone Common Market, Latin American trade organization established in 1991, full members: Argentina, Brazil, Paraguay, and Uruguay; associate members: Bolivia, Chile, Colombia, Ecuador, Peru, and Venezuela) is the world's third largest economic union. It is a vital region that Korean corporations should enter to preoccupy the Latin American market. Since China and Japan are recently moving strongly to advance into MERCOSUR, Korea needs to work out measures to cope with the situation. In trading with MERCOSUR, it is very important to establish a strategic base in the market from a long-term perspective rather than to approach the market only as an exporting market. From this viewpoint, Korea should regard MERCOSUR as a market with which it should cooperate in terms of resources, beyond a market from which it imports raw materials. Helped by its advancement strategies varying according to regional markets and price competitiveness, China is bolstering its market share in these regions. In addition, China has built production bases focused on electric and electronics products. It is also increasing its investments in MERCOSUR as a stable raw material-providing base. To make inroads into MERCOSUR successfully, therefore, Korean enterprises should not regard it as a market where it disposes of stock goods, but should instead export technologically competitive goods to this region. Likewise, Korean companies should expand their investments in automotive parts and machinery in MERCOSUR. Furthermore, Korea should closely study international trading policies of MERCOSUR to clear away any possible obstacles of exports to this region and to prepare countermeasures so as to avoid possible damage from import regulations of MERCOSUR.

Hyphessobrycon eques is a famous fish for ornamental fish market and aquarium. They are inhabit in regions of Amazon and Paraguay River basin. Serpae fishs were investigated 2-3 males are chased to female, and then males attempted to simulate the females abdomen. After fertilization, eggs were kept in incubators at $28^{\circ}C$. The fertilized eggs had adhesive and demesal characteristics and had a mean diameter of $0.92{\pm}0.01mm$. Larvae hatched at 16 hrs post fertilization. The hatched larvae averaged $2.90{\pm}0.16mm$ in total length ($L_T$). Complete yolk sac resorption and mouth opening occurred on the third day post hatching. At 45 days post hatching, the larvae were $12.5{\pm}1.60mm$ $L_T$ and had reached the juvenile stage.

Stevia rebaudiana (SR) is an herb used traditionally as a sweetener in Paraguay and Brazil, whose use is spreading to other countries, such as Japan, Korea and China. In addition to its low calorie sweet taste, SR appears to have other beneficial properties, such as hypotensive capabilities and inflammation reduction. To identify the bioactive natural constituents exerting anti-inflammatory activities, we examined the EtOAc fraction of SR. In the inflammatory mediator inhibitory assay from lipopolysaccharide (LPS)-activated macrophages, the EtOAc fraction significantly, and dose dependently, inhibited the enhanced production of nitric oxide (NO) and inducible nitric oxide synthase (iNOS) expression. We also found that treatment of cells with the EtOAc fraction significantly inhibited LPS-stimulated nuclear factor-${\kappa}B$ (NF-${\kappa}B$) reporter gene expression. Such inhibition of NF-${\kappa}B$ was closely associated with the inhibition of interleukin-6 (IL-6) and the monocyte chemoattractant protein-1 (MCP-1). Therefore, we suggest that SR has the potential for development as a functional food for the treatment of immune diseases, such as rheumatoid arthritis and lupus.
