Information and Communication Technology (ICT) has the potential to provide economic opportunities and help raise the social and political status of countries. For developing countries, ICT can be used as a tool for economic growth and social advancement in a short period of time. The benefits of ICT, however, are not only economic in nature. It can help improve professional skills, teaching quality, job creation, agricultural production, community involvement, and information use, personal relationships, and time use. These benefits are examples of how ICT has become an indispensable part of our lives. Myanmar is a developing country and is ranked low in the ICT Development Index. In terms of ICT development, Myanmar today is facing many issues such as a lack of telecommunication infrastructure, ICT awareness, electricity, and budget for ICT development. Among the economic reforms implemented by the recent government, the telecommunications sector has been opened up as a measure of economic reform. As a result of this reform, the telecommunications sector has been growing rapidly. Myanmar, however, remains behind other Asian countries. This paper discusses Myanmar's ICT infrastructure status, progress that has been made in the country's telecommunications over the last fifteen years, and the challenges that lie ahead.

For the past few years, the Korean government has been consistently expanding its national research & development budget to accelerate economic growth through technology innovation and the enhancement of international competitiveness in global markets. The objective of this paper is to define the concept and analyze the current status of national R&D programs by measuring R&D efficiencies. We determine R&D efficiency by reflecting inputs and outcomes of the five main agricultural R&D programs between 2010 to 2015, and by categorizing and regrouping figures that may affect R&D performance. Among 1,128 targeted projects, 832 projects with patents and thesis were selected for analysis in terms of measuring technology efficiency, pure technology efficiency, and efficiency of scale. Also, the Kruskal-Wallis test was also utilized as well. As a result of empirical analysis, figures that affected the efficiency level of national R&D programs included differences in research resources, research management levels and skills, and research field. This study can be utilized as a reference for re-establishing national agricultural R&D policies, such as enhancement of national technology competitiveness in the global market environment, improving and adapting to new agricultural conditions, market expansion, national agricultural R&D efficiency, aging rural population, agricultural management cost increase, and climate change mitigation.

게임 콘솔에서부터 TV, 그리고 헐리우드 영화에 이르기까지 3D 렌더링 테크놀러지는 많은 분야에 쓰이고 있다. 컴퓨터로 이미지를 렌더링하는 방법은 90년대 후반까지는 Phong Shading을 위주로 하는 Rasterization 방식의 렌더링이 주를 이루었으며 이 방식은 최근에까지 영화나 극장용 애니메이션의 렌더링에 주력으로 쓰여 왔다. 21세기에 들어서는 레이 트레이싱(Ray Tracing)과 그 발전형인 글로벌 일루미네이션(Global Illumination)이 사실감과 퀄러티로 대두되면서 건축 렌더링부터 시장을 점유해갔으나, 글로벌 일루미네이션은 극장용 애니메이션이나 영화에 주력으로 사용되기에는 렌더링 시간이 비현실적으로 느린 경우가 많았다. 따라서 본 논문은 각 렌더링 방식의 개념적, 수학적 이해를 살펴본 후 앰비언트 어클루전(Ambient Occlusion)의 함수를 Rasterization방식에서 사용하는 Illumination Loop 식에 접목시켜서 글로벌 일루미네이션처럼 다양한 색의 조명을 반영하면서도 Rasterization처럼 빨리 렌더링 할 수 있는 알고리즘 수식과 이 수식을 사용한 RenderMan Shader 사용 예를 제시하였다. 이는 글로벌 일루미네이션이 나타낼 수 있는 사실적인 표현, 그리고 Rasterization방식의 빠른 속도, 이 두 가지 렌더링 방식의 장점만을 조합하여 짧은 렌더 타임을 유지하면서도 쉽게 좋은 퀄러티를 얻을 수 있는 새로운 개념으로써 이러한 방법은 이후 애니메이션이나 영화 VFX 제작에 있어서 제작비의 절감과 함께 좀 더 완성도 있는 결과물을 만들어 내는 역할을 할 수 있는 계기가 되길 바란다.

Background: For Korean pharmaceutical industry to continue to grow, it is requisite to enter the global markets of developed countries. However, the export volume has fallen short of 10% of the gross sales and the industry has only recently warming up to prepare the globalization along with suchlike the Columbus Project. Purpose: This research was conducted to identify the difficulties Korean pharmaceutical companies perceived and to discover the gap in the needs for the government aid the companies have been seeking in the purpose of entering the developed pharmaceutical markets. Method: A survey method was used for this research. Six experts were surveyed and provided comments for the pre-questionnaire. Then, a final questionnaire was developed consisting of 10 items on regulatory-related and another 10 items on non-regulatory-related factors in drug exportation using the Likert scale (1 to 5). The survey sample was 30 Korean companies which have participated in the Columbus Project since 2010. Results: Nineteen (63%) companies responded to the survey. Most companies perceived difficulty (mean = 4.19) over the entire pathway of the regulatory process of global markets. Clinical trials and post-marketing surveillance were remarked as the most difficult barrier to follow the regulatory globalization. Among non-regulatory related factors, marketing, arranging a distribution network, obtaining experts, and projecting a timeline in exportation were brought up as the most difficulty. Conclusion: Especially, cost and language barrier were considered as the main cause producing these difficulties across regulatory and non-regulatory processes and accordingly, securing both long term budget and experts at governmental level was suggested by the domestic pharmaceutical companies.

Sludge transporting pipes in wastewater treatment plant are easy to be clogged with struvite when the digested sludge and dehydrated filtrate are transported through the pipes, which lowers the efficiency of sludge treatment system in a WWTP. pH is one of the most important factors in struvite formation, and carbon dioxide separated from biogas can be used to control pH and struvite formation. By controlling pH, the amount of dehydrating agent can be reduced by about 10%, which saves the budget for facility maintenance. As $CO_2$ is reused and dehydrating chemicals are saved, the approach can contribute to global warming gas reduction.

The three dimensional structure of thermohaline circulation in a D-plane is investigated using a conceptual two layer model and a scaling argument. In this simple model, the water mass formation region is excluded. The upper layer represents the oceans above the main thermocline. The lower layer represents the deep ocean below the thermocline and is much thicker than the upper layer. In each layer, geostrophy and the linear vorticity balance are assumed. The cross interfacial velocity that compensates for the deep water mass formation balances downward heat diffusion from the top. From the above relations, we can determine the thickness of the upper layer, which is the same as thermocline depth. The results we get is basically the same as that we get for an f-plane ocean or the classical thermocline theory. Mass budget using the velocity scales from the scaling argument shows that western boundary and interior transports are much larger than the net meridional transport. Therefore in the thermohaline circulation, horizontal circulation is much stronger than the vertical circulation occuring on a meridional plane.

The number of connected computers in the Internet, which has reached a state in which its address space is becoming insufficient is exponentially increased. Also nowadays modern Laptops and Mobile terminal are being used more and more. As hewn, the number of available IPv4 address is limited and many organizations have limited budget to use the global address. So the way to overcome such problems is using private addresses in their networks. In addition, the use of private address makes the system more secure. Moreover, we have considered about supporting of the scalability of data forwarding processes of nodes in their network especially Mobile IP data communication. Thus, we propose the integration of MPLS and Mobile IP network. Also we propose the security services of a constrained LSP for the MPLS payloads.

A DEM(digital elevation model) is generated from a SPOT panchromatic stereo-pair using automated algorithms over a 8 km$\times$10 km region around Mokpo city. The aims are to continue the accuracy assessment over diverse conditions and to examine the applicability of a SPOT DEM for coastal disaster monitoring. The accuracy is assessed with respect to three reference data sets: 10 global positioning system records, 19 leveling data, and 1:50,000 topography map. The planimetric error is 10.6m r.m.s. and the elevation erroer ranges from 12.4m to 14.4m r.m.s.. The DEM accuracy of the flat Mokpo region is consistent with that over a mountainous area, which supports the robustness of the algorithms. It was found that coordinate transformation errors are significant at a few meters when using the data from leveling and topographic maps. The error budget is greater than the requirements for coastal disaster monitoring. Exploiting that a sub-scene is used, the affine transformation improves the accuracy by 50% during the camera modeling.

We consider the D2D sum utility maximization in the cellular system. D2D links reuse the uplink resource of cellular system. This reuse may cause severe interference to cellular users. To protect the cellular users, interference limit from the D2D links is required. In this setting, D2D sum utility maximization problem is investigated. Each D2D link has limited transmit power budget. Because optimum solution may require global information between links and computational complexity, we propose the distributed algorithm which only require the local information from each D2D link and simple broadcasting. Simulation results are provided to verify the performance of the proposed algorithm.
