에센셜 오일은 고대로부터 향을 즐기거나 직접 상처 부위에 바르는 등의 다양한 방법으로 사용해 왔다. 일반적으로 에센셜 오일을 얻을 수 있는 허브와 스파이스는 약 200종 정도이며 흔히 주변에서 볼 수 있는 것으로는 레몬이나 오렌지, 장미, 제라늄, 민트 등이 있다. 이들 식물의 꽃잎(장미), 잎사귀(유칼립투스), 뿌리(베티본), 고목(샌달우드), 송진(프랭킨센스), 줄기(버베나), 열매(베르가못) 등 여러 부분에서 독자적인 방법으로 추출할 수 있는 에센셜 오일은 식물의 강한 생명의 힘으로 종종 언급되었다. 이는 방향성, 비지방성의 100% 천연의 식물에서 추출한 물질이며, 저마다의 고유한 향과 각기 다른 독특한 생명력과 치유능력을 가지고 있다. 이러한 에센셜 오일을 사용함에 있어서 우리는 감정 치유와 신체 건강을 향상시킬 수 있다. 모든 에센셜 오일은 항-박테리아, 항-바이러스 또는 항균성을 지니고 있다. 연구 조사에 따르면 아로마(향)는 인간의 감정 센서에 직접적인 영향을 끼치는데 이는 우리 신체의 감각 중심의 뇌에 직접적으로 아로마 향이 투입되기 때문이다. 우리의 후각을 통해 뇌 시스템을 직접 통과하여 감정, 행동, 냄새를 판단하는 것을 총괄하게 된다. 항상 아름다운 냄새를 통해 즐거워 하고 우리의 감정 균형을 유지시키므로 에센셜 오일을 사용함에 있어 그 향기가 우리에게 즐거움을 주는 것은 중요한 일이다. 이 오일을 통해 우리의 감각신경이 균형을 유지하게 될 것이다. 이러한 에센셜 오일을 이용하여 마음의 건강, 정신의 건강, 신체의 건강을 향상시키며 유지할 수 있도록 유지, 관리하는 것이 아로마테라피이다. 아로마테라피는 적게는 담배로부터 향수까지 광범위하게 가장 화려한 글로 설명되어 왔다. 에센셜 오일을 사용함에 있어 우리 신체의 가장 좋은 투입 방법으로 마사지 법이 있으며 우리 피부는 에센셜 오일을 놀라울 만큼 빠르게 흡수해 낸다. 이러한 효능의 에센셜 오일을 피부관리시에 적용하여 신체의 건강뿐만 아니라, 정신의 건강을 향상시키며 유지 할 필요가 있다고 본다.

Among the hypotheses regarding the internal process of industrialization, the debates about 'labor-surplus' model have been intensive. The basic idea of this neoclassical theory is that industrial development is brought about by the transfer of the unlimited cheap labor to the modern sector, and thus, under the labor-surplus situation labor-using technologies should be used for industrialization. Fei and Rannis attempted to confirm this theory by applying it to the Japanese economy. The purpose of this paper is to study whether the theory can be applied to Korean economic development. The neoclassical dualistic model which was designed by Kelly and Williamson was utilized. Simulating Korea's major economic variables for the period of 1965-1992 by using computable general equilibrium (CGE) model, we found that there are significant differentials between the simulation and the actual data. It suggests that Korea's economic development has not followed the neoclassical path -- creation of comparative advantage on the basis of market force.

Due to their geographic proximity to Beijing, the Southeast Asian states under the fallout of the China's growing power are struggling to seek the art of diplomacy to promote their national interests. This study explores why Cambodia previously taking a pro-US strategy after the end of the Cold War has switched to a pro-China one in the context of the rise of G-2 system, the ASEAN regionalism, the country's national interest and Hun Sen's regime legitimation. Theoretically, this study takes a realist constructivist approach and tries to find how realist interests and norms have affected the Hun Sen's regime legitimation. The relationship between China and Cambodia has been deepened by mutual economic interdependence and increasingly stronger Chinese power. Especially, the Chinese massive economic aids and investment have enormously supported the regime legitimation of Hun Sen. On the other hand, The US value diplomacy promoting democracy and human rights has undermined the Hun Sen's legitimacy and strained the two nations' relationship. However, the Hun Sen's pro-China strategy is not to check and balance against US strategic interests and not to recognize the Chinese hegemonic position in Southeast Asia. It is a hedging against the US value diplomacy while maximizing economic and other gains from China. ASEAN has been playing a coordinating role to limit the scope of power politics among big powers and to mitigate its ramifications. Yet, since the US and Chinese interests are so keenly criss-crossing, Cambodia may continue to react to the G-2 system through bilateral relations with them.

지난해 우리나라는 주요 10대업종중 <조선>과 <건설>을 제외하고 대부분의 업종이 3저의 영향으로 생산, 내수, 수출등 제분야에서 고루 균형을 가진 호황의 한 해였다. 우리나라는 본원적으로 부존자원이 없는데다가 외채자본에 의존한 결과, 경제적 자립성을 유지하기 위해서는 부득이 해외시장에 의존하지 않을 수 없다. 그러기 때문에 정부는 지 금까지 수출주도형 고도성장정책을 견지해 왔으며 이 결과 국제수지의 적자와 물가상승등 부작용이 뒤따른것도 사실이다. 아뭏든 지난해의 우리나라 경제를 요약하면 경제성장- 물가안정-국제수지흑자로 이어졌는데 결국 세마리의 토끼를 한꺼번에 잡은 행운의 한 해 였음이 분명하다. 특히 값진 보람이라고 한다면 지금까지의 만성적인 국제수지적자가 추 방되고 사상초유의 흑자원년을 기록했다는 사실이다. 이렇게 볼 때, 우리기업인들은 행운이였다고 하기 이전에 주어진 기회를 재빠르게 포착하여 이용했다는 사실에서 그 저력을 과시하는 표현이 더욱 적절할 것 같다. 금년에도 또 몇마리의 토끼를 잡기 위해서는 고속성장보다는 안정된 기조하에서 수출주도형의 경제정책이 계속 밀고나가야할 것으로 생각 된다. 3저현상은 무한히 지속하는 것이 아니며 언제 무산될지 모르는 미래에 대비하여 사전 에 그 대응책이 마련되어야 하며 이 처방은 경쟁 우위력에서 구해내야할 것이다. 따라서 우리 는 축적된 경험과 <노우하우>를 바탕으로 품질의 고급화, 생산성향상, 부가가치의 증진등으로 선진국 대열에 진입할 수 있는 힘을 키워야 하며 이것은 오직 노사협조라는 평범한 진리에서 얻을 수 있다. 금년도 년초에 대통령의 국정연설에서 <올해는 우수한 기술. 기능인이 대폭 육성되고 이들이 산업현장에서 자기의 꿈을 키울 수 있도록 더욱 효과있는 지원제도를 발전해 나갈 것이다...>라고 하였고 또 <이같은 과학기술의 진흥과 산업현장의 기술. 기능인력을 양 성하는 데 역점을 둔다...>는 최고지도자의 구상은 바로 우리가 기대했던 공감대를 형성하였 다고 본다.

This paper presents the theoretical analysis of a flow driven by surface tension and gravity in an inclined circular tube. A governing equation is developed for describing the displacement of a non-Newtonian fluid(Power-law model) that continuously flows into a circular tube owing to surface tension, which represents a second-order, nonlinear, non-homogeneous, and ordinary differential form. It was found that quantitatively, the theoretical predictions of the governing equation were in excellent agreement with the solutions of the equation for horizontal tubes and the past experimental data. In addition, the predictions compared very well with the results of the force balance equation for steady.

We developed the model equations to investigate the particle movement and growth theoretically in a-Si plasma CVD reactor, where those particles act as the source of contamination. We included the effects of fluid convection, particle diffusion and external forces (ion drag force, electrostatic force and gravitational force) onto the particles to analyze the movements of particles in plasma reactor. Taking into account the particle charge distribution, the particle growth by coagulation between the charged particles was investigated. Most of those particles are located in the region near the sheath boundaries by the balance between the ion drag and electrostatic forces. The particle concentrations in the sheath region and in the bulk plasma region are almost zero. The sizes of the predator particles increase with time by the coagulation with protoparticles and, as a result, the surface area and the average charge of predator particles also increase with time.

Pneumatic system is widely applied to ground facility and launcher on-board system. The main requirements of pneumatic system is to meet pressure and flow requirements of gas consumers. For launcher related applications, different from other applications, very high flow is required which can leads to supply pressure drop against required setting pressure. The supply pressure decrease is closely related to regulator characteristics. In this paper, the characteristics of pneumatic regulator related to supply pressure decrease and the control methods for reducing the pressure offset are reviewed.

Based on the application of te theory of conjugate approximations and the Loubignac's iterative method in a local region, a method to improve the stress filed in a displacement-formulated finite element solution has been proposed. The validity of the proposed method has been tested through two examples : a thick cylinder under internal pressure loading and an infinite plate with a central circular hole subjected to uniaxial tension. As a result of analysis of the examples, it was found that the stress field obtained for the local region model by the proposed method approximates well for the whole domain model. In addition, it was found that because of a significant decrease in the computing time to obtain the improved stress field, the proposed method is efficient and useful for the detailed stress analysis in local regions.

This paper describes the development process of high stiffness body for ride and handling performance. High stiffness and light weight vehicle is a major target in the refinement of Passenger cars to meet customers' contradictable requirements between ride and handling performance and fuel economy This paper describes the analysis approach process for high stiffness body through the data level of body stiffness. According to the frequency band. we can suggest the design guideline about lg cornering static stiffness, torsional and lateral stiffness, body attachment stiffness. The ride and handling characteristic of a vehicle Is significantly affected by vibration transferred to the body through the chassis mounting points from front and rear suspension. It is known that body attachment stiffness is an important factor of ride and handling performance improvement. And high stiffness helps to improve the flexibility of bushing rate tuning between handling and road noise. It makes possible to design the good handling performance vehicle and save vehicles to be used in tests by using mother car at initial design stage. These improvements can lead to shortening the time needed to develop better vehicles.

Buoyancy-assisted melting of an unconstrained ice in an isothermally heated horizontal enclosure was numerically analyzed in a range of wall temperatures encompassing the density inversion point. The problem as posed here involves two physically distinct domains each of which has its own scales and respective heat transfer mode. These two domains join at the junction where the liquid squeezed out of the film region flushes into the lower melt pool. Both of these domains have been treated separately in the literature by a patching technique which invokes several, otherwise unnecessary, assumptions. The present study eliminates successfully such a superfluous procedure by treating the film and lower melt pool regions as a single domain. As a result of this efficient solution procedure, the interaction of the water stream ejected at the junction and the natural convection in the melt pool could be clarified for different wall temperatures. Though limited by two-dimensionality, the present results conformed indirectly the earlier reported transition of the flow pattern, as the wall temperature was increased over the density inversion point. The transient evolution of the melting surface, the time rate of change in melt volume fraction, the local and temporal variation of the heat transfer coefficients are analyzed and presented.
