沿海地区是世界上大多数沿海国家人口密度很大的地区之一。尼日利亚拉各斯沿海地区是一个明确了解沿海地区内部动态的国家。拉各斯州位于尼日利亚西南区域,地理位置优越,海岸线绵延180多公里,海拔高度为39m(129ft),沿着贝宁湾的几内亚海岸延伸至大西洋沿岸。拉各斯州由3755平方公里的土地组成,其中70%是湿地和水体。人口规模1200万,其增长率为4.19%,并在过去五年中持续增长,这一比例在统计学上十分重要。本研究考察了拉各斯沿岸管理的可持续性,观察了目前管理制度的差距以及造成这些差距的原因。根据拉各斯沿岸管理的调查结果,提出了综合沿海管理(ICM),将其作为一种管理概念引入,其特点和整体方法对沿海管理产生的影响,这与目前的沿海管理制度形成了对比。本研究采用广泛的文献复习、访谈、综合分析和比较分析等研究方法。利用欧洲联盟和世界银行提出的原则,对ICM作为沿海管理概念的有效性和适用性进行了评估。利用欧洲联盟和世界银行提出的原则,对拉各斯国家的沿海岸地区进行了全面分析,这帮助我们制定了成功实施ICM的指标。然后,利用本研究开发的ICM原则、模型和指标,并结合即将实施ICM的拉各斯州的广泛研究,评估了将ICM在拉各斯州实施的可能性。从这项研究的结果来看,鉴于尼日利亚拉各斯州的环境脆弱性和经济及人口重要性,在拉各斯州采用和实施化管战略的必要性被认为是相当重要的。建议在拉各斯州采用国际海洋管理的建设性应用,采纳和实施国际海洋管理战略作为可持续海岸管理概念的一个实际步骤,并考虑到本研究报告所强调的益处,可能将其扩大到国家这一层级。这项研究的目的是对拉各斯州沿海地区目前所观察到的多部门产生的管理差距的认识,并为可持续的沿海管理制定一个切实可行的管理方法,该方法源于ICM概念。还需要为尼日利亚拉各斯州关于可持续沿海岸管理的进一步研究和讨论提供更多的背景数据。

Besides the Indonesian throughflow(ITF), the South China Sea throughflow(SCSTF) also contributes to the water transport from the Pacific to the Indian Ocean. However, this South China Sea(SCS) branch at the Karimata Strait is poorly observed until 2007, even though its importance has been suggested by numerical studies for decades. In this paper, we review the nearly 10-year field measurement in the Karimata Strait by the execution of the projects of "SCS-Indonesian Seas Transport/Exchange(SITE) and Impacts on Seasonal Fish Migration" and "The Transport, Internal Waves and Mixing in the Indonesian Throughflow regions(TIMIT) and Impacts on Marine Ecosystem", which extend the observations from the western Indonesian seas to the east to include the main channels of the ITF, is introduced. Some major achievements from these projects are summarized.

The experiment involves creating a sound wave that propagates down a pipe with 8 transducers attached at equally spaced intervals of 0.01016 m. The numerical method—the Cross Correlation Method, used to solve for the phase component, creates a high correlation value, but the speed of sound varies immensely. The method involves a Fast Fourier Transform (FFT) of the collected data, which is used to find the phase of the sound wave, and the slope of the position versus time graph, which is used to calculate the speed of sound. This high correlation value shows that the data are correct, but the numerical method for analyzing the data is incorrect.

Retinal vasculature is a network of vessels in the retinal layer. In ophthalmology, information of retinal vasculature in analyzing fundus images is important for early detection of diseases related to the retina, e.g. diabetic retinopathy. However, in fundus images the contrast between retinal vasculature and the background is very low. As a result, analyzing or visualizing tiny retinal vasculature is difficult. There-fore, enhancement of retinal vasculature in digital fundus image is important to provide better visualization of retinal blood vessels as well as to increase accuracy of retinal vasculature segmentation. Fluorescein angiogram overcomes this imaging problem but it is an invasive procedure that leads to other physiological problems. In this research work, the low contrast problem of retinal fundus images ob-tained from fundus camera is addressed. We develop a fundus image model based on probability distribution function of melanin, haemoglobin and macular pigment to represent melanin, retinal vasculature and macular region, respectively. We determine retinal pigments makeup, namely macular pigment, melanin and haemoglobin using independent component analysis. Independent component image due to haemoglobin obtained is used since it exhibits higher contrast retinal vasculature. Contrast of reti-nal vasculature from independent component image due to haemoglobin is compared to those from other enhancement methods. Results show that this approach outperforms other non-invasive enhancement methods, such as contrast stretching, histogram equalization and CLAHE and can be beneficial for retinal vasculature segmentation. Contrast enhancement factor up to 2.62 for a digital retinal fundus image model is achieved. This improvement in contrast reduces the need of applying contrasting agent on patients.

Nowadays E-learning as a form of learning depending on networks and computer devices has been expanding by leaps and bounds. As a special kind of E-learning, M-learning (mobile learning) aims at the use of mobile devices anywhere at anytime by anybody. In this paper, the technologies to develop a M-learning system are deeply analyzed according to the layer model at first. Then, from the view of application, the standardization in M-learning is researched in order to accelerate the development and popularization of M-learning. Finally, quality estimation of M-learning system is discussed from the view of QoE (quality of experiences). The experience form end-user is the sole effective norm to judge the result of M-learning technology. It is no doubt that technologies, standardization and evaluation will play very important parts in the course of M-learning development.

Introduction: Interleukin-2 (IL-2) is multiple which functions during an inflammatory response. Inflammation is a critical component of cancer progression. IL-10 is the most important cytokine with anti-inflammatory properties. Cancer patients typically show depression of both cellular and humoral immune functions. aims: The objective of this experiment is to know the expression of IL-2 and IL-10 in cervical cancer. Method: Paraffin block of the tissues frozen section cervical cancer was cut in sharp and cleaned cryotome and place in glass plate that covered with poly-elysine. The immunohistochemistry stains were done with monoclonal antibody anti IL-2 and IL-10 with TSA-indirect method. The collected data were analyzed with T Test (SPSS for window 15). Result: In this study the expression of IL-2 (35.9% = moderate) is less than the expression of IL-10 (45.3% = moderate). From T Test analysis of p <= 0.153, it means that there is no significance in difference between IL-2 and IL-10. Conclusion: We indicated that the immune response plays a role in balance between cellular and humoral immunity.
