Objective: Oilseeds and nut co-products can be used as alternative feed ingredients in animal diets because they may have a lower cost than traditional ingredients. A study was, therefore, conducted to determine the chemical composition of copra, palm kernel, and nut co-products from South-East Asia or Australia. The hypothesis that country of production influences nutritional composition was tested. Methods: Oilseed meals included 2 copra expellers, 3 copra meals, and 12 palm kernel expellers. One source of almond hulls and cashew nut meal were also used. Samples were obtained from suppliers located in South-East Asia or Australia. All samples were analyzed for dry matter, gross energy, nitrogen, amino acids (AA), acid-hydrolyzed ether extract (AEE), ash, minerals, insoluble dietary fiber, and soluble dietary fiber. Copra and nut co-products were also analyzed for total starch and sugars. Results: Copra expellers had greater (p<0.05) concentrations of dry matter and AEE compared with copra meal. However, copra meal had greater (p<0.05) concentrations of total dietary fiber (soluble and insoluble) and copper than copra expellers. Palm kernel expellers from Indonesia had greater (p<0.05) concentration of histidine and tyrosine compared with palm kernel expellers from Vietnam. Almond hulls was high in dietary fiber, but also contained free glucose and fructose, whereas cashew nut meal was high in AEE, but low in all free sugars. Conclusion: Copra expellers have greater concentration of AEE, but less concentration of total dietary fiber when compared with copra meal, and except for a few AA, no differences in nutrient composition of palm kernel expellers produced in Indonesia or Vietnam were detected. According to the chemical composition of nut co-products, cashew nut meal may be more suitable for non-ruminant diets than almond hulls.

Although Vietnam has a high risk of fish borne zoonotic trematode(FZT) infections for humans, little information exists on the epidemiology of these infections in the country's fish. Because of the importance of cultured cat-fish and snakehead production in An Giang province, a major production area in the Mekong Delta of Vietnam, a survey for FZTs was carried out in randomly selected fish farms between June 2005 and March 2006. For comparison, wild fish from the same area were also surveyed. A total of 852 cultured fish from 4 districts were collected and examined by pepsin digestion to determine their FZT infection status. In Tra catfish, the prevalence of all types of metacercariae was 2.6%, of which the prevalence of Haplorchis pumilio was 0.7%. The overall prevalence of metacercariae in wild fish was 30.6%, of which 10.3% harbored zoonotic species: H. pumilio(2.8%) and Procerovum sp.(5.6%). The prevalence of Opisthorchis metacercariae, which were diagnosed as O. viverrini, was 1.9%. No metacercariae were found in cultured snake head fish, although wild-caught snakehead fish had a FZT prevalence of 10.3%: 5.1% were O. viverrini; 2.6% H. pumilio; and 2.6% were Procerovum sp. These are the first reports of H. pumilio, Procerovum sp., and O. viverrini metacercariae in Vietnamese fish. These results indicate that consumption of improperly prepared fish represents a significant risk of acquiring FZTs in this south Vietnam region.

It is a commons sense that the Republic of Korea is a maritime state that depends its survival on International Trade and International Economy. Korea was a peninsula and do it can be both maritime and continental state by its choice. However, after the national division in 1945, South Korea had became a virtual island and pursue a maritime way for national development in the past 60 plus years. Now, South Korea is becoming a world's 12 th largest major trading and maritime state. South Korea has far more ships per capita than any other nations in the world and its economy is heavily depend upon the imports and exports with other nations in the world that pass through the oceans. Therefore, the Koreans regard the security of the sea lanes of communication as vital to the survival of the nation. The SLOC is the life line for Republic of Korea. Since the early 1990s, immediately after the Cold War was over, South Koreans began to recognize the importance of Sea Routes and thus began to build a navy that can handle with the new problems of the post Cold War era. However, the maritime security environments of the Republic of Korea today is shaky and dangerous. Almost every water near the Korean peninsula, some kind of international confrontations are going on. Territorial disputes on Dok do, Senkaku, Scarbrough, Shisha, Nansha and Eodo between and among Korea, Japan, China, Taiwan, Phillipines, Indonesia and Vietnam are the examples. In this essay, the author argues that the S. Korean efforts and capabilities to deal with these challenges are not enough and exhorts more efforts and more powerful navy for the Korean people.

The purpose of this study is to summarize tropical cyclone activity in 2007. 24 tropical cyclones of tropical storm (TS) intensity or higher formed in the western North Pacific and the South China Sea in 2007. The total number is less than the thirty-year (1971~2000) average frequency of 26.7. Out of twenty four tropical cyclones, 14 TCs reached typhoon (TY) intensity, while the rest 10 only reached severe tropical storm (STS) and tropical storm (TS) intensity - four STS and six TS storms. The tropical cyclone season in 2007 began in April with the formation of KONG-REY (0701). From April to May, two TCs formed in the western North Pacific in response to enhanced convective activity there. From June to July, convective activity turned inactive over the sea around the Philippines and in the South China Sea, and the subtropical high was weak over the south of Japan. MAN-YI (0704) and USAGI (0705) moved northwestward and hit Japan, bringing serious damage to the country. After August, convective activity became enhanced over the sea east of the Philippines, and the subtropical high turned strong over the sea south of Japan. Many TCs, which formed over the sea east of the Philippines and in the South China Sea, moved westward and hit China and Vietnam. PABUK (0706), WUTIP (0707), SEPAT (0708), WIPHA (0712), LEKIMA (0714) and KROSA (0715) brought serious damage to some countries including China, the Philippines and Vietnam. On the other hand, FITOW (0709) and NARI (0711) moved northward, bringing serious damage to Japan and Korea. After HAIYAN (0716), all four TCs except FAXAI (0720) formed over the sea east of $140^{\circ}E$. Three typhoons among them affected Republic of Korea, MAN-YI (0704), USAGI (0705) and NARI (0711). Particularly, NARI (0711) moved northward and made landfall at Goheng Peninsula ($34.5^{\circ}N$, $127.4^{\circ}E$) in 1815 KST 16 September. Due to $11^{th}$ typhoon NARI, strong wind and record-breaking rainfall amount was observed in Jeju Island. It was reported that the daily precipitation was 420.0 mm at Jeju city, Jeju Island on 16 September the highest daily rainfall since Jeju began keeping records in 1927. This typhoon hit the southern part of the Korean peninsula and Jeju Island. 18 people lost their lives, 14,170 people were evacuated and US$ 1.6 billion property damage was occurred.

On October 27, 2015, USS Lassen(DDG82), a 9,200 ton class Aegis destroyer of the United States Navy, began its operations within 12 nautical miles of Subi Reef, one of the seven artificial islands that China has built and claimed sovereignty over. The maneuver was joined by anti-submarine patrol airplanes such as P-8A and P-3. The White House press secretary mentioned that the President of the United States approved the operation. In response, China announced that it warned the US Navy ship about the 'illegal violation' by sending two destroyers(PLAN Lanzhou and Taizhou). This event represents a close call case where tension between the United States and China in the South China Sea might have been elevated to a conflict between the two navies. Moreover, considering that this happened only one month after Chinese president Xi's state visit to the United States, the event shows that the positions of the two countries have become starkly different to the extent that they are so hard to be reconciled. The United States' position is different from those of Vietnam and the Philippines. Countries like Vietnam and the Philippines have been directly involved in disputes with regard to sovereignty claims across the waters in the South China sea. As for the United States, being a third party in the disputes, it still cannot be a by-stander watching the whole waters in the region fall under the influence of China. Accordingly, the United States maintains that all countries bear the rights of innocent passage and military operations in the Exclusive Economic Zones(EEZ) as stipulated by the United Nations Convention on the Law of the Sea(UNCLOS). In contrast, China claims that, historically, the South China sea has been part of China's territorial waters, and that foreign countries are not allowed to conduct military operations within the waters. It strongly accuses that such military operations are illegal. Against this background, this paper tracks the different positions of the United States and China on the issues regarding the South China sea. It also carefully looks at the possibility that, in the process of dealing with the issues, the two countries may get into an armed conflict as the phrase 'Thucydides Trap' predicts.

The Korean Peninsula is geographically located in the centre of Far Eastern Asia and has complex and various climate conditions following longitudinal topology, which would expect to be result in high diversity and endemism of millipede. In this study, the millipede fauna of the Korean Peninsula consists of 68 species plus 5 subspecies from 29 genera, 15 families and 7 orders. Of these species/subspecies, 29 and 12 are endemic in South Korea and North Korea, respectively; nine are recorded in both South Korea and North Korea. Each species has been provided comprehensive information including an original report, taxonomic changes, distribution, and remarks if necessary. Moreover, unsolved taxonomic uncertainty of some species included in this checklist should be investigated through further study.

The effect of change in exchange rates on an economy is very important, especially, to a small open economy like South Korea. I explore whether Free Trade Agreements (FTAs) have positive influences on exchange rate-pass through import price of import market for fishery products in South Korea. Competition among FTA partners is enhanced after FTAs are effective. I expect that the extent to which are exchange rate pass-through (hereafter, ERPT) into import price of fishery products (in terms of Korea currency) would be reduced since the import market for fishery products in South Korea is an oligopolistic market. Specifically, I investigate two research questions with six South Korea's FTA partners-Norway, Thailand, Peru, U.S., China and Vietnam. First, whether the extent to which are exchange rate pass-through into import price of fishery products from six FTA partners would decrase in the post-FTA era; seconds, the size of reduction has a negative relation with the size of their market share in the import market for fishery products in South Korea if it decreases. The empirical results indicate that the degree of ERPT into import price from other FTA partners than Norway has been reduced after FTA, statistically and significantly; however, I do not find the evidence that the size of reduction is related to their market share. The findings in this study imply that FTAs have negative effects on producers' economic welfare in South Korea's fishery industry by reducing the extent to which are exchange rate pass-through as well as reducing tariff barriers.

This study investigates the competitiveness of the clothing and textile industry in North Korea, compare to those of China, Hong Kong, India, Indonesia, Japan, South Korea, Thailand, and Vietnam from 1993 to 2010; in addition, it explores the potential cooperation between South Korea and North Korea. First, a revealed comparative advantage (RCA) was used to investigate the competitive performance of clothing and textile industry in North Korea. The results reveal that North Korea and Viet Nam had superior comparative advantages from 1993 to 2010. Second, in order to investigate the factors that affect the competitive performance, depth interviews based on Porter's Diamond of Competitive Advantage were designed and completed by government officers and practitioners working in the clothing and textile industry field. The results show that cheap labor, the stable demand of South Korea and China for basic products, lack of supporting and related industries, and organizational power highly influence the competitive performance of clothing and textile in North Korea. This result provides insight into the potential and limitations of the clothing and textile business. In addition, this study provides a better understanding of the effects of inter-Korean economic cooperation in socialist states.

이 글은 최근 베트남 사회에서 일어난 변화를 몇 가지로 나누어 설명하고자 한다. 첫째, 베트남의 세계경제로의 통합과 자본주의화를 이상적인 것으로 상정하고 작성된 각종 보고서와 논문을 활용하여 2017년 베트남 경제의 특징적 변화를 소개한다. 둘째, 베트남의 자본주의로의 이행을 보는 서로 다른 시각을 포괄하면서 베트남 경제의 최근 변화와 위기를 중장기적으로 평가하고, 전망하고, 진단하고자 한다. 셋째, 최근 대두된 정치적, 사회적 이슈를 놓고 공산당 내부에서 벌이고 있는 정치과정의 양상과 이로 인한 권력관계의 변화를 추적한다. 넷째, 이상에서 논의한 베트남의 정치경제적 변화에 영향을 미치고 있는 대외관계의 환경과 이에 대한 베트남 정부의 대응을 설명한다. 이 과정에서 25주년을 맞이한 한국-베트남 관계의 의미에 대한 평가도 간략하게나마 시도해보고자 한다. 마지막으로, 최근 베트남의 사회문화적 변화를 염두에 두면서 대중이 개혁개방정책 이후 일어나고 있는 체제의 변화에 어떻게 반응하고 있는지 성찰해보고자 한다. 2017년은 베트남인에게 자본주의를 향해 순항하는 경제, 이로 인한 인민의 욕구의 분출에 대한 정치적 논란과 통제, 그리고 중국과 미국을 중심으로 커지고 있는 대외관계의 불확실성과 이에 대한 다각적 대응 등으로 기억될 만한 해였다. 2017년 한 해 동안 일어난 이러한 현상들은 사회주의를 표방하고 있는 베트남이 시장경제 모델을 채택하면서 지속적으로 경험해나갈 수밖에 없을 것으로 보인다. 문제는 이러한 경험이 장기적으로 사회주의 베트남의 인민에게 동의를 얻어내며 지속될 수 있는 것인지 아니면 저항을 양산하게 될 것인지 불확실하다는 점이다. 지금처럼, 빈부격차의 확대, 부패와 권력의 독점, 미숙련 저임금 노동자의 양산이 지속되는 한 진정한 의미의 동의를 구하기는 어려울 것이다. 다시 말해, 지금처럼 정치경제적 변화를 위한 개발과 산업화가 환경, 건강, 복지에 부정적 영향을 주고 있는 한 동의 대신 불만의 축적이 불가피할 것이다. 이런 점을 고려할 때 2017년 한 해에 이룬 수치상의 경제성장, 표면적인 정치안정, 대외관계에 대한 기민한 대응이 향후 얼마나 지속가능한 것인지 관심을 가지고 지켜볼 필요가 있다.
