Linear programming has become an important tool in decision-making of modern business management. This remarkable growth can be traced to the pioneering efforts of many individuals and research organizations. The popular using of personal computers make it very easy to process those complicated linear programming models. Furthermore advanced linear programming software packages assist us to solve L.P. models without any difficult process. Even though the advanced L.P. professional packages, the needs of more detailed deterministic elements for business decisions have forced us to apply dynamic approaches for more resonable solutions. For the purpose of these problems applying to the "Mathematica" packages which is composed of mathematic tools, the simplex processes show us the flexible and dynamic decision elements included to any other professional linear programming tools. Especially we need proper dynamic variables to analyze the shadow prices step by step. And applying SAS(Statistical Analysis System) packages to the L.P. problems, it is also one of the best way to get good solution. On the way trying to the other L.P. packages which are prepared for Spreadsheets i.e., MS-Excel, Lotus-123, Quatro etc. can be applied to linear programming models. But they are not so much useful for the problems. Calculating simplex tableau is an important method to interpret L.P. format for the optimal solution. In this paper we find out that the more detailed and efficient techniques to interpret useful software of mathematica and SAS for business decision making of linear programming. So it needs to apply more dynamic technique of using of Mathematica and SAS multiple software to get more efficient deterministic factors for the sophiscated L.P. solutions.

언론에서 소셜 미디어는 미래 지향적이면서 선구자적인 이미지로 묘사될 때가 많다. 소셜 미디어의 확산에는 이러한 언론 보도가 중요한 역할을 하고 있다. 그래서 이 논문에서는 언론의 소셜 미디어 담론에 대한 분석을 통하여 그것이 어떠한 사회적 함의를 가지는지를 살펴보고자 한다. 그 결과 언론에서 소셜 미디어는 사회의 발전과 민주적인 커뮤니케이션을 위해 필연적인 당위성을 가진 것으로 묘사되고 있다. 또한 거부할 수 없는 사회적 변화의 흐름인 것으로 묘사되고 있었다. 기업, 정부, 정치인, 일반인들까지 소셜 미디어 이용에 적극적인 자세를 보이는 것으로 보도되었다. 프라이버시 침해와 같은 소셜 미디어의 부정적인 면은 거의 보도되지 않았다. 이러한 언론의 보도태도는 새로운 미래를 향한 진보의 시간에 필요한 규율적 훈련을 사람들이 받아들이도록 하는 것을 의미한다.

On the grounds of Diane Vaughan's pioneering study into the Challenger Disaster, STS(Science and Technology Studies) scholars have recently argued that most engineers seldom face an ethical situation, in which the boundary between the ethical and the unethical is absolutely clear, and for which a serious moral decision such as "whistle blowing" is urgently needed. They have instead suggested that engineering ethics needs to address engineers' everyday routine practices, which, if accumulated, may have some impact upon the overall performance of the technological system. However, such studies have not completely resolved the tension between STS that emphasizes contextual elements in which the everyday practice of engineers are done, on the one hand, and engineering ethics that stresses individual engineer's moral decision of an existential kind, on the other. By discussing various works on the Challenger Disaster and related issues over technological risks, this paper attempts to establish an interface between STS and engineering ethics, and proposes some practical implications for the effective education of engineering ethics to engineering students.

CarboKorea and HydroKorea are the domestic projects aiming to improve our understanding of carbon and water cycles in a typical Korean forest located in a complex terrain with a watershed connected to large rivers. The ultimate goal is to provide a nowcasting of these cycles for the whole Peninsula. The basic strategy to achieve such goal is through the inter- and multi-disciplinary studies that synthesize the in-situ field observation, modeling and remote sensing technology. The challenge is the fact that natural ecosystems are nonlinear and heterogeneous with a wide range of spatio-temporal scales causing the variations of mass and energy exchanges from a leaf to landscape scales. Our paradigm now shifts from temporal variation at a point to spatial patterns and from spatial homogeneity to complexity of water and carbon at multiple scales. Yet, a large portion of our knowledge about land-atmosphere interactions has been established based on tower observations, indicating that the development of scaling logics holds the key to the success of CarboKorea and HydroKorea. Here, we review the pioneering work of FIFE (First ISLSCP Field Experiment) on scaling issues in a temperate grassland and discuss the lessons from it for the application to Gwangneung forest site.

In early 1990s, the Korean government has launched a deep-sea research program to secure the stable long-term supply of strategic metallic minerals including Cr, Cu and Ni. Through the pioneering surveys, Korea registered $150,000km^2$ of Mn-nodule field in the Clarion-Clipperton area, the NE equatorial Pacific to the international sea-bed authority (ISA) in 1994. Following the ISA exploration code, the final exclusive exploration area of $75,000km^2$ was assigned in 2002, based on results of eight-year researches of chemico-physical properties of nodules, bottom profiles and sediment properties. Since that time, environmental studies, mining technical developments including robot miner and lifting system and establishment of smelting systems were accompanied with the detailed geophysical studies to decipher the priori mining area until 2009. Major points of the recent Korea Mn-nodule program are deployed on a commercial scale until 2015. In order to meet the goals, we developed a 1/5 scaled robot miner compared to commercial one in 2012 and performed a mining test at the water depth of 1,370 m in 2013. In addition, detailed 25,000 scaled mining maps in the priori area, which can provide operation roots of the miner, will be prepared and an environmental-friendly mining strategy will be pursued based on the environmental impact test and environmental monitoring.

The purpose of this research is to be acquainted with the awareness and approval of halal supply chain among Indian manufacturers and distribution network members for haulage and warehousing activities from the perception of respective service suppliers. A total of 20 respondents, which consist of 10 transportation companies and 10 warehousing companies from the State of Andhra Pradesh in India were selected for the study by using purposive sampling method. The principal focal points of the discussions are on awareness and adoption of halal transportation and warehousing services chosen for the study in the comprehensive halal supply chain. A total of 90 percent and 70 percent of respondents from the transportation and warehousing companies respectively agreed that they know only about the concept of halal but do not have any exposure and ken on the halal supply chain. However, findings of this research won't have extensive validity in the market, gaining an enough familiarity with the halal supply chain in the Indian social context is of immense importance. This is a pioneering attempt aimed to investigate the awareness and adoption levels of halal supply chain among Indian businessmen which are precious for supply chain companies to customize their services in the country as well to the world of academia.

Intensity interferometry, based on the Hanbury Brown--Twiss effect, is a simple and inexpensive method for optical interferometry at microarcsecond angular resolutions. Motivated by recent technical developments, we argue that the sensitivity of large modern intensity interferometers can be improved by factors up to approximately 25,000, corresponding to 11 photometric magnitudes, compared to the pioneering Narrabri Stellar Interferometer of the 1970s when resolving. Our approach, based on spectrally resolved light, permits the construction of large optical interferometers at the cost of (very) long-baseline radio interferometers. Realistic intensity interferometers are able to spatially resolve main-sequence O-type stars in the Magellanic Clouds. Multi-channel intensity interferometers can address a wide variety of science cases: (i) linear radii, effective temperatures, and luminosities of stars; (ii) mass-radius relationships of compact stellar remnants; (iii) stellar rotation; (iv) stellar convection and the interaction of stellar photospheres and magnetic fields; (v) the structure and evolution of multiple stars; (vi) direct measurements of interstellar distances; (vii) the physics of gas accretion onto supermassive black holes; and (viii) calibration of amplitude interferometers by providing a sample of calibrator stars.
