Recently, many authors have studied twisted -Bernoulli polynomials by using the -adic invariant -integral on . In this paper, we define and study the twisted weak weight -Bernoulli polynomials and numbers. And, we derive some various identities related to the twisted weak weight -Bernoulli polynomials.

In 1713, J. Bernoulli first discovered the method which one can produce those formulae for the sum $\sum\limits_{\iota=1}^{n}\;\iota^k$ for any natural numbers k ([5],[6]). In this paper, we investigate for the historical background and motivation of the sums of powers of consecutive integers due to J. Bernoulli. Finally, we introduce and discuss for the subjects which are studying related to these areas in the recent. 수학에서 가장 매력적이고 중요한 이론들 중에 하나로 알려진 베르누이 (Bernoulli)수의 변천과정을 고찰한다. 즉, 당시대의 이러한 연속된 정수의 멱의 합에 대한 수학사적 배경들을 조사하고, 베르누이 수와 관련된 연구들이 현재 어떠한 방향으로 진행되고 있는지를 살펴본다.

A Navier-Stokes code has been developed to simulate the flow through a cross flow fan. It is based on an unstructured finite volume method and uses moving grid technique to model the rotation of the fan. A low Reynolds number turbulence model is used to calculate eddy viscosity. The basic algorithm is SIMPLE. Numerical simulations over a wide range of flow rate are carried out to validate the code. Comparison of all numerical solutions with experimental data confirms the validity of the present code. Present numerical solutions show a noticeable improvement over a previous numerical method which is based on a model of body force to simulate the rotation of the impeller.

General consensus on typical vertical profile of dissolved oxygen in the Ulleung Basin is that dissolved oxygen concentration beyond 300 m decreases with increasing depth. However, the results of our observations in 2005 and 2006 revealed three different dissolved oxygen distribution types in the deep layer of the Ulleung Basin. The first type showed oxygen concentration decreasing with increasing depth (Type- 1), the second showed oxygen concentration decreasing very sharply near the bottom boundary layer but constant in the bottom adiabatic layer (Type-2), the final was of the oxygen minimum layer above the bottom boundary layer (Type-3). Type-2 was the most common pattern in the Ulleung Basin. Type-1 was most common close to the Japan Basin, including the Ulleung Interplane Gap, while Type-3 was found around Dok do. Oxygen Consumption Rate (OCR) at surface sediment estimated using the dissolved oxygen distribution at the bottom boundary layer was 0.2~5.8 mmol·m−2 d−1, which coincided with OCR from direct sediment incubation. This implies that organic matter decomposition at surface sediment may play an important role in dissolved oxygen distribution patterns at the bottom boundary layer of the Ulleung Basin.

Industrial heritage artifacts may include the industrial products, technologies and infrastructures that have contributed to modernization beginning with the Industrial Revolution. The history of our industrial heritage spans 50 to 150 years and can be characterized by taking into account the site and the technology. This paper analyzes 13 precedents in Japan, Canada, and the United States in terms of these concerns, with focus on the reuse of abandoned mines as industrial heritage. Field surveys and interviews about each abandoned mine were used to obtain historical records and material. The results describe progress in three phases (1) recognizing phase, (2) organizing phase, and (3) maintenance management phase. A proper methodology for reuse is necessary to ensure the authenticity of the abandoned mine, particularly in the face of poor tourism-oriented approaches. As a result of analyzing the 13 cases, we determined that the following principles should be considered during the reuse process. Firstly, reuse of abandoned mines should not be compulsory but should be a spontaneous process and especially, should be carried out by inhabitants. Secondly, education and real experiences in the abandoned mine should be used to ive visitors a feeling of authenticity. Thirdly, creative remodeling methods can be used to enhance the abandoned mine's facilities and the site. Finally, historic and new functions should be the focus of the revitalization. Because this paper mainly focused on 13 precedents, there are likely more diverse cases. However, the conclusions of this report have practical value for reuse of abandoned mines and can be used in establishing methods for reusing Korean abandoned mines as industrial heritage.
