The purpose of this study was to investigate if an community forestry programme (HKm) could be one of the main tool for REDD+ in Indonesia. Recently, considerable numbers of countries including Norway, England, Korea and etc. have invested 69 million US$ in total to Indonesia for implementation of REDD+. However, forest dependent people without a communal right are subject to poor forest governance during a stream of REDD+ in Indonesia. This study suggest that HKm are needed to be a tool for REDD+ in order to achieve the objects of REDD+ in terms of Equity, Efficiency, and Effectiveness (3Es) by stimulating local and Indigenous peoples to participate in REDD+. As a result of our study, Indonesia government have designated only 200,000 ha for HKm area by 2007. Indonesia government have a week political will to extend its area to give a communal right to those peoples who dwell in state forests and HKm application process is complicated and slow. HKm has a potential to be main tool for REDD+ in Indonesia. However HKm will be difficult to be main tool for REDD+ without resolving current obstacles.

Korean shipbuilding industry increased a considerable amount of orders recently. It is time to build up the concept of Digital-Ship, and develop the fundamental technology to operate or manage an oceanic vessel safety and also economically for the world shipping industry, now. In this paper, all sorts of low-ranked devices, system components, integrated protocol, and ship-shore supporting system, which shares information between ship and shore by utilizing a low-orbit satellite communication will be described.

To maximize astaxanthin (3,3'-dihydroxy-$\beta\beta$'carotene-44'-dione) production by high density Haematococcus pluvialis cultures, various, media were examined Among tested media, \`Hong Kong Medium and Modified Bolds Basal Medium showed the best result for cell growth ( $2.0$\times$10^{ 6}$cells /mL) and for astaxanthin content per cell (9.7 mg astaxanthin mg/g cell), respectively, Maximum astasanthin concentration of 6.1mL was obtained at pH 7.5, $20^{\circ}C$~$25^{\circ}C$ Deficiencies of nitrogen source($NaNO_3$ and proteose-peptone) found to simulate astaxanthin formation Relatively low light inten- sity of $60\mu$E ($\m^2$s) was sutiable for vegetative cell growth while higher light intensity was required for higher astaxanthin accumulation.

In the paper, the p-ranks and characteristics polynomials of cyclic difference sets are derived by expanding the trace expression of their characteristic sequences. By using this method, it is shown that the 3-ranks and characteristic polynomials of Helleseth-Kumar-Martinsen (HKM) difference set and Lin difference set can be easily obtained.

A conceptual design of marine environmental information system(MEIS) for vessels running in the ocean was carried out. MEIS consists of a remote acquisition system of raw environmental data, a physical and numerical processing system of acquired raw data, and a supporting satellite communication system for data transfer. The efficiency of a remote acquisition system depends on the amount of acquired data and its real-time accessibility, while the efficiency of a data processing system is governed by the flexibility and accuracy of data analysis tools.

This article discusses the state of a community forestry program in a protection forest in Indonesia, which has been running for almost two decades. We found that the program did not achieve its objective mainly because of frequent changes in regulations. There are also activities such as: measuring and mapping working area boundaries, drawing up a work plan, planting, maintenance and security, paying royalties to those who harvest forest resources, and submitting annual reports on land use to the district government head, which have not worked as expected. We also found that the major incentives for local people to participate in the program are getting certificates of management and the program's effectiveness in minimizing land-use conflicts. Participants perceived that their major role on the program is to follow farmer-group directives or government rules. To achieve the program's purposes, farmer groups need technical assistance related to protection-forest management and opportunities for financing.

Digital-ship is the next-generation ship with an one-man bridge system which consists of INS(Intelligent Navigation System), AIS(Automatic Identification System), and IMIT(Integrated Maritime Information Technology). INS implements the functions is related of the ship's navigation, and supports in the digital GIS environments optimal route planning, stranding and a collision avoidance among the ship, an economic navigation, and an integrated control of ship's engine. AIS prevents the ship's collision by means of transmitting periodically the own ship's information to the other ship or the shore control center. IMIT systems supports the integrated fiat-form in ships, the communication between a ship and a control center of the land using the INMARSAT, OrbComm, Ocean Observation Satellite, and etc. The satellite communication in ships can monitor the ship at an earth control renter. This paper deals with the method for system implementation of digital-ship and the detailed sub-system.

Interfacial and microfailure properties of the modified steel, carbon and glass fibers/cement composites were investigated using electro-pullout test under tensile and compressive tests with acoustic emission (AE). The hand-sanded steel composite exhibited higher interfacial shear strength (IFSS) than the untreated and even neoalkoxy zirconate (Zr) treated steel fiber composites. This might be due to the enhanced mechanical interlocking, compared to possible hydrogen or covalent bonds. During curing process, the contact resistivity decreased rapidly at the initial stage and then showed a level-off. Comparing to the untreated case, the contact resistivity of either Zr-treated or hand-sanded steel fiber composites increased to the infinity at latter stage. The number of AE signals of hand-sanded steel fiber composite was much more than those of the untreated and Zr-treated cases due to many interlayer failure signals. AE waveforms for pullout and frictional signals of the hand-sanded composite are larger than those of the untreated case. For dual matrix composite (DMC), AE energy and waveform under compressive loading were much higher and larger than those under tensile loading, due to brittle but well-enduring ceramic nature against compressive stress. Vertical multicrack exhibits fur glass fiber composite under tensile test, whereas buckling failure appeared under compressive loading. Electro-micromechanical technique with AE can be used as an efficient nondestructive (NDT) method to evaluate the interfacial and microfailure mechanisms for conductive fibers/brittle and nontransparent cement composites.
