  • In the present study, a flow solver using a kinetic BGK scheme was developed for the compressible Navier-Stokes equation. The kinetic BGK scheme was used to simulate flow field from the continuum up to the transitional regime, because the kinetic BGK scheme can take into account the statistical properties of the gas particles in a non-equilibrium state. Various numerical simulations were conducted by the present flow solver. The laminar flow around flat plate and the hypersonic flow around hollow cylinder of flare shape in the continuum regime were numerically simulated. The numerical results showed that the flow solver using the kinetic BGK scheme can obtain accurate and robust numerical solutions. Also, the present flow solver was applied to the hypersonic flow problems around circular cylinder in the transitional regime and the results were validated against available numerical results of other researchers. It was found that the kinetic BGK scheme can similarly predict a tendency of the flow variables in the transitional regime.

  • The effects of an inserted coil on flow . patterns and heat transfer performance for a horizontal rotating heat pipe have been studied experimentally. Especially, the present study is to see an internally inserted helical coil inside a RHP would lead to the same kind of results as internal fins. Visualization test conducted for an acryl tube, charged water with at a volumetric rate of 20%. When the flow kept pool regime at a low rpm(less than 1,000rpm), the movement of coil forced the water to flow in axial direction. But this pumping effect of coil disappeared, when the pool regime changed to annular one which could be created by increasing rpm. The pumping effects for RHP with an inserted coil resulted in the enhancement in both condensation heat transfer coefficient and heat transport limitation, as obtained in case of using internal fins. But all these effects became negligible in the range of higher rpm(above 1,000-1,200) with the transition of flow regime to annular flow.

  • 2018년 5월 9일, 61년간 지속되던 말레이시아 집권연합인 국민전선(BN, Barisan Nasional)이 출범 2년차에 불과하던 야당연합인 희망연합(PH: Pakatan Harapan)에 의해 전격적으로 교체되었다. 총선에 출마했던 당사자들 조차 예측하지 못한 야당의 압승이었기에 1957년 독립 이후 최초로 이루어진 정권교체는 그야말로 순식간에 일어났다고 해도 과언이 아니다. 2018년 총선에서 BN의 패배는, 북한과 중국을 제외하고, 현존하는 현대정치체제 중에서 가장 오랫동안 지속되었던 패권적 집권세력의 몰락을 의미하였기에 세계적인 관심을 주목시켰다. 더욱이 이번 총선은 야권의 분열로 말미암아 1998년 개혁정국(reformasi) 이래 꾸준히 성사되었던 여야 간 일대일 대결이 무산되면서 모든 선거구에서 단일 여당 후보와 복수 야당 후보 간의 경선으로 치러졌기 때문에 그 결과는 더욱 놀랍고 충격적이었다. 도대체 어떻게 이런 결과가 일어날 수 있었는가? 특히 20년 가까이 지속된 야권의 공조에도 요원했던 정권교체가 야권의 분열에도 불구하고 이번 선거에서 달성될 수 있었던 동인은 무엇인가? 2018년 총선 결과는 말레이시아의 정치변동과 민주화 가능성에 어떠한 정치적 함의를 제공하는가? 앞으로 말레이시아 정국은 어떤 방향으로 전개될 것인가? 이에 대한 해답을 찾는 과정에서 1998년 개혁정국이 조성된 이후 치러진 일련의 총선들이 말레이시아 정가에서 "쓰나미(tsunami)"의 연속에 빗대어 비유되는 경향이 있음에 주목할 필요가 있다. 이런 쓰나미의 연속이라는 현상은, 비록 학계와 시민사회의 말레이시아 전문가들은 물론이고 정부여당과 야권 내부에서조차도 이번 총선에서의 정권교체 가능성을 예견한 사람은 거의 없었지만, 이번 총선에서의 정권교체가 갑자기 일어난 것이 아니라 지난 20년 간 지속된 말레이시아 유권자들의 선거를 통한 정치변동의 열망과 기대가 축적된 결과이라는 것을 의미한다. 이런 맥락에서, 이 연구는 2018년 총선 결과를 분석함에 있어서 독립 이후 최초로 정권교체가 달성될 수 있었던 특수한 상황적 요인과 함께, 1998년 개혁정국에 의해 촉발된 선거정치의 활성화가 결국 선거권위주의 체제의 붕괴로까지 귀결될 수 있었던 역학관계에 주목한다.

  • 본 시험은 broiler 사육에 있어 점등방법이 broiler 증체나 사료요구율에 미치는 영향을 구명하기 위하여 시판사료를 이용하여 1986년 4월3일부터 동년 3월 21일까지 49일간에 걸쳐 실시하였으며 broiler 감별 웅추 180수를 공시하였다. 시험구는 24시간 연속점등 방법(24L), 1시간 점등에 3시간씩 소등하는 간헐점등 방법(24L), 1시간 점증에 3시간씩 소등하는 간헐점등 방법(1L+3D), 20시간 점등에 4시간 소등하는 방법(20L+4D) 및 자연일조시간을 이용하는 방법(Natural)등 4개 처리하였으며 그 결과를 요약하면 다음과 같다. 1. 전시험기간중의 증체량은 1L+3D구가 가장 높았으며, 20L+4D구, 24L구, Natural 구 순으로 낮아졌으나 각 처리간에 유의차는 인정되지 않았다. 2. 전기 4주간의 증체량은 1L+3D구와 20L+4D구가 Natural구와 24L구보다 현저히 높았으나 각 추리간에 유의차는 없었다. 각 구별로는 1L+3D구가 가장 증체량이 높았으며, 20L+4D구, Natural 구, 24L 구 순으로 낮아졌다. 3. 후기 3주간의 증체량은 24L구, 1L+3D구, 20L+4D구, Natural구 순으로 낮아져서 전기와는 상이한 경향을 보였으나 각 처리간에 유의차는 없었으며 증체량도 거의 차이가 없었다. 4. 전시험기간중 사료요구율은 1L+3D구가 가장 좋았으며, 20L+4D구, Natural구, 24L구 순으로 나빠졌으나 각 처리간에 유의차는 인정되지 않았다. 사료섭취량은 각 처리가 거의 같은 수준을 나타내어 각 처리별 점등방법이 공시계가 충분히 사료는 섭취하는 데는 시간이 부족하지 않았음을 알 수 있었으며, 사료 섭취후 일정시간 활동을 억제하는 것이 사료요구율 개선에 좋은 영향을 미쳤음을 관찰할 수 있었다. 5. 전기 4주간의 사료요구율은 1L+3D구와 20L+4D구가 Natural 구와 24L구에 비하여 현저히 좋았으나 각 처리간에 유의차는 없었다. 각 구별로는 1L+3D구가 가장 사료요구율이 좋았으며 20L+4D구, Natural구, 24L구 순으로 나빠졌다. 6. 후기 3주간의 사료요구율은 1L+3D구가 가장 좋았으며 24L구, 20L+4D구, Natural구 순으로 전기와는 상이한 경향을 보였으나 각 처리간에 유의차는 없었으며 사료섭취량도 거의 차이가 나지 않았다. 이상의 결과를 종합해 볼 때 broiler에 있어 일정시간 점등과 소등을 계속하거나 일정시간 소등을 해주는 간헐점등 방법이 24시간 연속점등방법이나 자연일조시간 방법보다 증체량이나 사료요구율에 좋은 영향을 주는 것으로 사료된다.

  • The study alms to identify how the symbols and images of Greek Roman myths in contemporary fashion have been reflected in respects of meaning and forms, and to find out the organic course from meaning to forms by using Durand's classification. The results define the significance of Greek Roman myths in contemporary fashion, and systematically suggest a direction of imagination for more creative design. In the diurne regime, the symbolism of purity, heroism and fear appeared. In the nocturne regime, the symbolism of maternity and sensuality appeared. In the dramatic regime, the symbolism of androgyny appeared. The characteristics of designs contained in each symbolism are common. In this regard, it is possible to trace organic relationships in the creation of images through the verbal scheme. In addition, the verbal scheme creates archetypal images that lead to images and symbols in the socio-cultural context, so it is possible to analyze the relationships between archetypal images and the format of garments. The study examined how the archetypal images that appeared in the mythical images were expressed in garments through the verbal system.

  • The nonlinear stochastic behavior of chaotic inflation is characterized by the 'scaling' effect. Using a simple criterion for the appearance of scaling behavior in the ${\lambda}{\phi}^4$ inflation model, we show explicitly that in this limit the onset of the scaling regime does not require any special initial conditions and that it is independent of the self-coupling constant ${\lambda}$. Non-Gaussian statistics in adiabatic fluctuations are important only for super-horizon scales and the scaling regime does not lead to any significant statistical properties on currently observable scales. However, the scaling effect gives some cosmological consequences very different from what we expect in the naive diffusion approximation for quantum fluctuations. The classical (deterministic) treatment of the inflation field (essentially a quantum mechanical object.) becomes valid towards the end of inflation.

  • The temperature in hot forming of metallic materials, such as hot extrusion and hot forging, ranges from $300^{\circ}C$ to $900^{\circ}C$. Correspondingly, the die also exhibits high temperatures close to that of a work piece and its life is limited generally by high temperature fatigue. Thus, the analysis of high temperature fatigue would need the mechanical properties over the wide ranges of temperature. However, very few studies on the high temperature fatigue of brittle materials have been reported. Especially, the study on the fatigue behavior over such transition temperature regime is very rare. In this paper, the stress-strain curves and stress-life curves of a die steel such as STD61 are experimentally obtained. The wide ranges of temperature from $300^{\circ}C$ to $900^{\circ}C$ are considered in experiments and the transition temperature zone is carefully examined.

  • In this paper, state of exploitation of world fishery resources after 10 years under the new regime in the sea, called the era of exclusive economic zone (EEZ) expending up to a 200 nautical miles from coastal line, was reviewed to determine effect from establishing EEZ in the world fishery production and its export/import volume based on the fishery statistics annually published by the Food and Agriculture Organization (FAO) of United Nation. The world total production from marine living resources had a trend showing a waned increase during 1970's when most of coastal states were translated into the reality of EEZ. From mid-1980's onwards, it increased rapidly, reaching about 85 million tons . Such increase in production was basically from the Pacific Ocean, accounting for more than 60% of the world total production. Fishing areas where showed increase in the production after the new regime in the sea were the southwestern Atlantic (FAO area 41) , the eastern Indian (FAO area 57) and the whole fishing areas in the Pacific except the eastern central Pacific (FAO area 77). Increase in the production from distant-water fishing countries came from the regions of the southwest Atlantic (FAO area 41) and the southwest Pacific (FAO area 81) . The production from coastal states was up from the regions of the eastern Indian (FAO area 57) , the northwest and northeast Pacific (FAO areas 61 and 67) and the southeast Pacific (FAO area 87) . It was likely that the exploitation of the fishable stocks was well monitored in the areas of the northwest Atlantic (FAO area 21) , the eastern central Atlantic (FAO area 34) and the northeast Pacific (FAO area 67) through appropriate management measures such as annual harvest level, establishment of total allowable catch etc. The marine fisheries resources that have made contribution to the world production, despite expansion of 200 EEZ by coastal states, were sardinellas, Atlantic cod, blue whiting and squids in the Atlantic Ocean : tunas which mainly include skipjack, yellowfin and bigeye tuna, croakers and pony fishes in the Indian Ocean : and sardine, Chilean pilchard, Alaska pollock, tunas (skipjack and yellowfin tuna) , blue grenadier and blue whiting including anchoveta in the Pacific Ocean. It was identified that both fishery production and its export since introduction of the new regime in the sea were dominated by such coastal states as USA, Canada, Indonesia, Thailand, Mexico, South Africa and Newzealand. But difficulties have been experienced in the European countries including Norway, Spain, Japan and Rep. of Korea. Therefore, majority of coastal states are unlikely to have yet undertaken proper utilization as well as rational management of marine living resources in their jurisdiction during the last two decades. The main target species groups which led the world fishery production to go up were Alaska pollock, cods, tunas, sardinellas, chub and jack mackerel and anchoveta. These stocks are largely expected to continue to contribute to the production. The fisheries resources which are unexploited, underexploited and/or lightly exploited at present and which will be contributed to the world production in future are identified with cephalopods, Pacific jack mackerel and Atlantic mackerel, silver hake including anchovies. These resources mainly distribute in the Pacific regions, especially FAO statistical fishing areas 67, 77 and 87. It was likely to premature to conclude that the new regime in the sea was only in favour of coastal states in fishey production.

  • An overall feature to simulate composite behavior and to predict closed solution has been performed for the application to the stress analysis in a discontinuous composite solid. To obtain the internal field quantities of composite, the micromechanics analysis and finite element analysis (FEA) were implemented. For the numerical illustration, an aligned axisymmetric single fiber model has been employed to assess field quantities. Further, a micromechanics model to describe the elastic behavior of fiber or whisker reinforced metal matrix composites has been developed and the stress concentrations between reinforcements were investigated using the modified shear lag model with the comparions between reinforcements were investigated using the modified shear lag model with the comparison of finite element analysis (FEA). The rationale is based on the replacement of the matrix between fiber ends with the fictitious fiber to maintain the compatibility of displacement and traction. It was found that the new model gives a good agreement with FEA results in the small fiber aspect ratio regime as well as that in the large fiber aspect ratio regime. It was found that the proposed simulation methodology for stress analysis is applicable to the complicated inhomogeneous solid for the investigation of micromechanical behavior.
