As the demand for bone mineral density testing increases in Korea, which is close to an aging society, it is necessary to evaluate the repeatability of equipment such as femur phantom other than l-spine for more accurate diagnosis. However, in clinical practice, it is often not possible to proceed such evaluation due to insufficient quality control conditions. Therefore, this study is to evaluate the usefulness of the femur phantom after fabricating the same using 3D printing technology. The femur phantom was output using GlowFill filament and FDM 3D printing type. Each phantom was repeatedly scaned 20 times to compare whether the existing l-spine phantom and the fabricated femur phantom were suitable as a phantom for quality control. Each time the seven researchers took three times, the location of the femur phantom was readjusted, and then scanned to confirm the error between the researchers. As a result of conducting repeatability evaluation using femur phantom, the coefficient of variation rate was 2%, which was within the minimum precision tolerance of 2.5%. The reproducibility between the researcher was also found to be suitable as the average coefficient of variation was 0.031 and the coefficient of variation rate was 3.1%, which was within the minimum precision error range of 5%. In conclusion, it is considered that the prospective attitude and usefulness of the femur phantom fabricated by 3D printing in clinical practice will be sufficient.

Vietnamese scholars contend that they have developed Southeast Asian studies viewing Southeast Asia as both a geographical entity with a long history and cultural tradition and a strategic region for modern development. This study has traced the construction of Southeast Asian studies as an academic discipline in Vietnam through the studies and arguments of Vietnamese scholars. It has put primary focus on the institutionalization of Southeast Asian studies, taking note of the assessment and perceptions of Vietnamese scholars. It also looked into the construction and limitations of Southeast Asian studies in Vietnam, which advocates Southeast Asian Studies as interdisciplinary area studies, with stressing of the origin of indigenous studies. The major contents of this study include: First, a historic overview of the institutionalization of Southeast Asian studies centering on research institutions of Southeast Asian studies in Vietnam, Second, the perceptions of Southeast Asian studies inside Vietnam and the inside evaluation of the effort to indigenize Southeast Asian studies. This study took note of Vietnamese scholars' perceptions and assessment of Southeast Asian studies performed by outsiders, primarily by Western scholars; the perceptions and evaluation of Southeast Asian studies conducted by Southeast Asian insiders; and the perceptions and evaluation of the origin of Southeast Asian studies indigenous to Vietnam. Last, it examined the construction and limitations of Southeast Asian studies in Vietnam, which advocates the studies as interdisciplinary regional studies.

Southeast Asia developed maritime trade from the early period due to the suitable physical and cultural conditions. The land consists of peninsular and archipelago, and located at the junction of the two monsoons in South China Sea and India Ocean. The people inherit cultural openness to receive outer influences positively. When Portuguese came to Southeast Asia in 16th century, the region had already enjoyed certain level of commercial development and sociocultural dynamics through the long time experience of interactions with outer world. The Portuguese contact to Southeast Asia was more of participation and assimilation than of conquest and rule experienced in South America. It was due to the higher level of spiritual and material civilization existed in Southeast Asia. Portuguese brought several new elements into Southeast Asia such as colonization and new weapons, Cartaz system and commercial monopoly, and Catholic mission and Casado policy. These new elements, however, did not impact much on the existing Maritime trade that played an important role to change the sociocultural structure of Southeast Asia. Even though Portuguese contact itself did not make significant differences in Southeast Asia, it was meaningful in a sense that it opened a path and left a model case for the more powerful Europeans who came soon after her.

소말리아 해적 문제는 전례가 없는 단계에 다다랐다. 2010년 까지만 해도 445대가 넘는 선박이 해적들로부터 피해를 당했으며 1,181여명의 사람들이 몸값을 위해 인질이 되어야 했다. 그러나 소말리아만이 해적문제가 이슈화 되는 곳은 아니다. 지난 20년간 동남아시아의 해적문제도 큰 이슈가 되어 왔다. 본 논문은 해적 행위의 원인, 영향, 그리고 유형의 분류에 대한 분석을 위해 두 가지의 사례 연구를 통해 이를 살피려 한다. 각각의 해적 관련 사례가 서로 다른 특징들을 가지고 있으나현재 신문이나 인터넷 상의 보도뿐만 아니라 학문, 법률상의, 그리고 공식적 문서들에서 얻어지는 정보들을 이용해 분석한 결과 해적 행위의 원인은 대부분 육지에서 발견된다는 것으로 결론을 낼 수 있다. 본 논문을 통해 제 국가들은 경제, 안보, 지리적인 이유의 이해를 달리 하여 해적 행위를 근절하려 한다는 것을 살펴본다. 또한 현재의 해적 행위에 대한 대응적 접근은 전체론적으로 육지에서의 원인에 근거하여 다루어지는 것이 아니라 바다에서의 해양법 시행에 집중되어 있다. 이는 해적의 소탕을 위한 과정이라기보다는 여전히 문제를 내포하고 있을 수밖에 없다는 점을 지적 하고자 한다.

동남아시아의 열대지역 동굴에서 톡토기를 채집하기 위해 Luzon(필리핀), 파푸아뉴기니아, Sulawesi(인도네시아), 말라야, 타이랜드에 수차 원정을 실시하였다. Acherontiella, Pseudosinella, Sinella, Oncopodura, Arrhopalites 등 속들이 조사지역의 모든 동굴에서 서식하고 있었다. 그러나 수개 속은 분포상 매우 제한되어 있었다. Troglopedetes는 동남아시아 대륙에서는 현저한 분화상을 보였으나 다른곳에서는 볼 수 없었다. Coecoloba는 파푸아 뉴기니아에서만 관찰될 뿐이고 멀리 떨어져 한국과 일본지역에서 다시 나타나고 있다. 대개의 종들은 토양산 계통으로 현재까지 유존종으로 생각되는 것은 발견되지 않았다.

The complete larval development of Enocheir japonicus De Haan reared in the laboratory is described and illustrated. E. japonicus passes through 5 zoeal stages before metamorphosis to the megalopal stage. The megalopa and crab I inStar are attained in 17 and 27 days after hatching, respectively. The culture was carried out under a photoperiod of 14 h light and 10 h dark and a constant temperature of $25^{\circ}C$. Morphological charaderistics of each larval stage of this species are compared with those of E. japonicus from Japan. Morphological features between zoea I of the Varuninae are briefly discussed.

One of main findings of the competitiveness relation is rapid increase of Chinese influence on the southeast Asian market. While Japanese market share is decreasing, Chinese market share is continuously increasing in the market. It is the same regardless of types of production phases. Analysis based on gravity model shows that in general Chinese exports is crowding out Korean and Japanese export to the market. The magnitude of the effects on Korean exports is larger than on Japanese exports. Also, It is found that the directions of the effect of Chinese exports on Korean and Japanese exports are different by production phrases. For all processed goods, increase of Chinese exports decreases both Korean and Japanese exports to the market. However, for some final goods such as transport equipment and food & beverages for household, Chinese exports is increasing Korean and Japanese exports to the market.

In the global economy, Korean foreign direct investment (FDI) to Southeast Asian countries expands rapidly as the countries try to make attracting investment strategies and to improve their investment condition. This paper, using panel-data for 2004-2006 in Indonesia, Vietnam and Malaya which are the main countries of Korean FDI for last ten years, shows analysis of the Korean FDI performance in Southeast Asia and compares the Korean firms' achievement with the case of China. According to the forty nine firms' official sources in Indonesia, Vietnam and Malaya, presented to the Export-Import Bank of Korea, over fifty percent of FDI consists of M&A. And Korean FDI has concentrated in the manufacturing industry. In order to measure the FDI performance, the study sets a regression function; operating profit ratio is the dependent variable and the total sales, expert ratio and investment period are the independent variables representing firms' volume, purpose of FDI and firms' adaptation to the local countries.
