본 연구에서는 세율이 비상장 중소기업의 투자활동에 미치는 영향을 분석하였다. 선행연구는 주로 상장기업을 대상으로 한 연구가 대부분으로 비상장 중소기업을 대상으로 세율과 투자활동의 관계를 살펴본 연구는 거의 없었다. 본 연구에서는 연구대상이 비상장 중소기업이므로 객관적인 재무자료의 입수에 어려움이 있어 선행연구를 토대로 작성한 설문지를 이용하였다. 본 연구를 위해 비상장 중소기업의 CEO와 근무자에게 500부의 설문지를 배부하여 243부를 회수하였고, 이 중 응답이 부실한 설문지 20부를 제외한 223부를 표본으로 선정하였다. 본 연구의 결과와 시사점을 요약하면 다음과 같다. 첫째, 세율이 인하되면 비상장 중소기업의 투자활동이 증가할 것이다는 가설 검증 결과, 세율의 회귀계수가 음(-)으로 통계적으로 유의한 영향을 미치는 것으로 나타났다. 이는 비상장 중소기업도 상장기업과 마찬가지로 세율이 인하되면 투자활동이 활발해진다는 것을 의미한다. 둘째, 기업특성과 구성원특성은 비상장 중소기업의 투자활동에 정(+)의 영향을 미치는 것으로 나타났다. 이는 비상장 중소기업의 경우, 기업특성에 따라 투자활동이 달라질 수 있으며, CEO의 의지에 따라 투자활동이 달라질 수 있다는 것을 의미한다. The purpose of this study is to analyze the impact of the tax rate on unlisted small & medium business in investing activities. Previous studies were primarily the research style for study of publicly traded companies, and most studies examined the relationship between tax rates and investment activities of unlisted small and medium businesses. In this study, because it is difficult to obtain objective financial data of unlisted small & medium business, questionnaire method was created on the basis of previous studies. In this study, 500 questionnaires distributed to workers and CEO of unlisted small business, and the 243 questionnaires was collected except 20 questionnaires to be answered poorly. The results and implications of this study can be summarized as follows. First, the tax rate cuts for unlisted small businesses will increase investment activity. Namely, the hypothesis testing results showed that the rate of regression coefficient is negative (-) and statistically significant effects. This means that even when the tax cuts for unlisted small & medium business as well as publicly traded companies increase investment activities. Second, the characteristics of company and member have an positive(+) influence on the investment activities of unlisted small & medium businesses. This means that investment activities of unlisted small & medium business can vary, depending on the characteristics of firm and the willingness of the CEO.

If the 20th century was the age of conflict for war and ideology, the 21th century can become the age of conflict for terror and crime. Also if the 20th century was ‘the American Century,’the 21th century can become the century of disorder. In this way the intelligence agency is supposed to be the most sensitive national organization dealing with the world that changes fast. The political environment of the Korean Peninsular is an area that the fighting of ideology still exists in the world. That area is also that powerful countries such as the US, Russia, China, and Japan is the place struggling for their national interests. In addition, the Korean Peninsular is an area that it is the transnational criminal syndicates such as Russian mafia, Japanese Yakuza, Chinese Triads to maximize illicit profits. When we see in view of organized crime at least, South Korea is very alike with circumstance that the late Chosun Dynasty was placed. Therefore, the Korea Peninsular is surrounded by powerful countries in the upper world as well as criminal groups in the underworld. In this context this paper is to analyze the new role and task of the national intelligence agency for the 21th century to deal with something urgent issues in the near future. 20세기가 전쟁과 이데올로기 투쟁의 시대였다면, 21세기는 테러와 범죄 와의 투쟁의 시대가 될 가능성이 높다. 또한 20세기가 미국의 세기였다면, 21세기는 무질서의 세기가 될 가능성이 높다. 이처럼 빠르게 변화하는 세 계에 대처하기 위해 가장 민감한 국가기관은 정보기관일 것이다. 한반도 주 변은 세계에서 유일하게 이데올로기의 투쟁이 존재하는 지역이다. 그 지역 은 또한 미국, 러시아, 중국, 일본 등 강대국들의 세력 갈등이 집약된 곳이 기도 하다. 뿐만 아니라 한반도 주변은 세계에서 유일하게 초국가적 범죄조 직들인 러시아 마피아, 일본 야쿠자, 중국계 삼합회 등 세계 6大범죄조직 들의 50%가 집중된 곳이기도 하다. 이런 맥락에서 적어도 조직범죄의 관 점에서 볼 때 한국은 구한말 조선이 처한 상황과 매우 유사하다. 따라서 한 반도는 지상세계의 강대국은 물론 지하세계의 범죄단체들에 의해 둘러싸인 형국이다. 이 글은 미래 위기상황의 도래에 대비해 21세기 정보기관의 새 로운 역할과 과제를 분석하는 것이다.

Formation comprises a distinctive set of sedimentary layers, which can be traceable laterally and mapped as a unit. It is a fundamental unit for stratigraphic position in a regional scale and provides an important basis for the interpretation of depositional processes and environments. This paper reviews the occurrence of the Jangsan Formation at the base of the Taebaek Group (Cambrian–Ordovician) in the Taebaeksan Basin and refines the geologic map unit for sedimentary characteristics and stratigraphic position. The refined Jangsan Formation comprises a set of distinctive sandstone (quartzite) with a number of sedimentary facies, including conglomerate, conglomeratic sandstone, and mudstone. The “Myeonsan Formation” is limited to a localized set, and leads it fallen into disuse. The refined Jangsan Formation can be reliably correlated with the equivalent early Cambrian sandstone unit (Liguan Formation) in Shandong Province, China about a thousand kilometers apart and elsewhere in the northeast Asian continent.

An axisymmetric jet is forced with two helical fundamental waves of identical frequency spinning in opposite directions and an additional axisymmetric sub harmonic wave. The subharmonic component rapidly grows downstream from subharmonic resonance with the fundamental, significantly depending on the initial phase difference. The variations of the subharmonic amplitude with the initial phase difference show cusp-like shapes. The amplification of the sub harmonic results in 'vortex pairing of helical modes'. Furthermore, azimuthal variation of the amplification induces an asymmetric jet cross-section. When the initial subharmonics is imposed with an initial phase difference close to a critical value, the jet-cross section evolves into a three-lobed shape. One lobe is generated by the enhanced vortex pairing and the other two lobes are generated by the delayed vortex pairing. Thus, it is confirmed that the initial phase difference between the fundamental and the subharmonic plays an important role in controlling the jet cross-section.

This study focuses on the initial subsidence mechanism of Korea Plateau in the East Sea. New interpretation of digitized multichannel seismic profiles (vertically unexaggerated) in the southern part of the South Korea Plateau delineates that acoustic basement comprises a number of normal-fault blocks, forming intra-plateau basins and troughs. In the western part of the plateau, the normal faults are oblique to the continental margin, whereas in the eastern part, they are bounded by an orthogonal transfer fault. The entire faults are suggestive of a large-scale dextral strike-slip fault system. The dextral fault system in the plateau was accompanied by a regional strike-slip fault along the North Korean continental margin, which offsets the prominent NE-SW granite belts on land and under the sea. The regional dextral strike-slip fault system activated during the late Oligocene/early Miocene to middle Miocene. The regional dextral strike-slip along the western continental margin of the sea was coupled with the complex dextral fault on the eastern margin from Sakhalin to Honshu. The regional strike-slip deformation was due to the changes in plate motion, i.e., southward drift (late Oligocene/early Miocene) and clockwise rotation (middle Miocene) of the Japanese Arc away from the Eurasian Plate.
