In this study, we developed a program of optimizing stand-level carbon stock using a stand-level yield model and the Simulated Annealing (SA) heuristic method to derive a optimized forest treatment solution. The SA is one of the heuristic algorithms that can provide a desirable management solution when dealing with various management purposes. The SA heuristic algorithm applied 'thermal equilibrium test', a thresholds approach to solve the phenomenon that does not find an optimum solution and stays at a local optimum value during the process. We conducted a sensitivity test for the temperature reduction rate, the major parameter of the thermal equilibrium test, to analyze its influence on the objective function value and the total iteration of the optimization process. Using the developed program, three scenarios were compared: a common treatment in forestry (baseline), the optimized solution of maximizing the amount of harvest(alternative 1), and the optimized solution of maximizing the amount of carbon stocks(alternative 2). As the results, we found that the alternative 1 showed provide acceptable solutions for the objectives. From the sensitivity test, we found that the objective function value and the total iteration of the process can be significantly influenced by the temperature reduction rate. The developed program will be practically used for optimizing stand-level carbon stock and developing optimized treatment solutions.

In RFID system, Tag's Identification data is processed in host computer by application program. Example of application program is parking administration program, library state program etc.. Tag's ID that is recognized in reader is inputted to the Host computer. Application program of computer searches data in DB of computer such as Tag ID. After finding the same ID, host computer send to control command to driver H/W in accordance with application purpose. But, It need to confirm in long distance whether achievement process is acted normally. There will be the 2 methods, when we monitors the process in long distance. One is wired monitoring system, another is wireless monitoring system. Among wire method, internet communication network is useful. RFID system manufacture first in this treatise. RFID system Embody using EM4095 chip that is doing 125KHz by carrier wave. Tag's characteristic ID is sent in remote place through module that use W3100A chip. This system Manufacture, and data send-receive confirmed using simple application program. Reception confirm by result, and pictures show by whole system and each part. And a control program explained of each part.

This paper analyse the learners' satisfaction for the usability of distance teaming system. We have analysed collected data regarding the learners' satisfaction with the online Master's in Library and Information Science (MLIS) program as an example. The learner responses from the focus groups broke down into the following five themes: General program issues, Course issues, Communication/interaction issues, On-campus experience issues, Technology issues. The feedback can be applied to most online learning environments as a guideline for teaching and developing of online course.

The Eco-performance assessment program was developed as part of Eco-performance management for buildings at the national level in developed countries. Cases of domestic Green Building Certification(GBC) system was developed but these program's destination of Eco-performance management for buildings needs systematic management by the limited GBC. Generally in the construction industry, Eco-performance management of Building Life-cycle is required. Therefore this paper develop the creation of Eco-performance information and management process, those are from design and maintenance management phases, through suggest the development of a information management for Eco-performance management of buildings. In addition, it makes to decrease the reproduction of information unnecessarily by analyzation of the related association between the information of facilities objects and Eco-performance management. Finally, study the previous reaserch and suggest the BIM by the method of information management and this paper purpose the development of web-based Eco BIM object library management system.

In this study we developed the visualization scheme of spatial ground-motion measurements in real time by using DSS data. Even though this scheme itself is useful for national earthquake mitigation plans, this scheme could be served as the crucial core for constructing rapid earthquake damage evaluation system. DSS is the abbreviation of Data Subscription Service and this is the pre-assigned request for the seismic stations to send very limited brief data with high priority and negligible transmission load. In addition to visualize the damage area with intensity, the corresponding epicenter can be estimated roughly for quick event alarm. For the interpolation of spatially irregular PGA data, the program, named as surface. of GMT was used with NetCDF grid file format. Since the grid file is similar to a postscript file, the program, called as shading, was coded with C language by using Matpak library in order to convert grid files into image files.

The permanence is of great importance to library and archival paper. According to the established standardizations including ISO and ANSI, the permanence can be specified with tear strength, pH, alkali reserve and kappa number. In this study, we evaluated the permanence and durability of domestic coated and copy paper grades. Two types of coated paper grades and all kinds of copy papers which were tested in this study were satisfied with the criterion of permanence specification. However, all of the tested paper grades didn't meet the requirements of durability because of their low folding endurance.

Telomerase reverse transcriptase (TERT) is an enzymatic ribonucleoprotein that prolongs the replicative life span of cells by maintaining protective structures at the ends of eukaryotic chromosomes. Telomerase activity is highly up-regulated in 85-90% of human cancers, and is predominately regulated by hTERT expression. In contrast, most normal somatic tissues in humans express low or undetectable levels of telomerase activity. This expression profile identifies TERT as a potential anticancer target. By using an RNA mapping strategy based on a trans-splicing ribozyme library, we identified the regions of mouse TERT (mTERT) RNA that were accessible to ribozymes. We found that particularly accessible sites were present downstream of the AUG start codon. This mTERTspecific ribozyme will be useful for validation of the RNA replacement as cancer gene therapy approach in mouse model with syngeneic tumors.

The purpose of this paper is to develop an integrated environment system for finite element structural analysis using OOA(Object-Oriented Analysis) and OOD(Object-Oriented Design), with may reduce inconveniencies in use such as file input of macro command and improve lacks of graphic presentation in the established finite element analysis program. This paper is attempted to suggest an easy approach to object-oriented concept and convenient programming. Two languages are used together in this paper instead of single C++ language for the development of object-oriented program. : Visual Basic with CDK(Custom Development Kit), and Borland C++ with OWL(Object Windows Library).

SNMP is a standard protocol for management of networking devices. Nowadays, most computer systems have capability to act as SNMP agents. In this paper, we describe our system monitoring software based on SNMP. It consists of a monitoring server, SNMP agents, and client programs. The monitoring server collects status information from the SNMP agents running on the monitoring target graphical display. We developed two version of clients, Java based standalone program and Web based program. Since most known SNMP packages are too big and heavy, we developed an efficient version of SNMP library for out system monitoring.
