This study was conducted to provide a rational forest management method for a natural oak (Quercus variavilis) forest stand in the central part of South Korea based on characteristics of growth and water relation parameters. Average volume per hectare was 175.1 ㎥ in the study site of oak stands. Basal area and volume of each direction appeared to increase as the slope direction moves from north to south, but annual mean increment and periodic annual increment of DBH for 10 years showed the lowest value at the southern aspect. Maximum water potentials measured between 12 and 14 o'clock were analyzed by direction and elevation in the oak stands. Water potential of oak decreased as the slope changed from the north to the south aspect and water potential increased at lower elevations. Soil water content for the oak stands tended to decrease as the aspect shifted from north to south. Water potential and soil moisture content were highly correlated. It appears that oaks have a higher moisture requirement at the southern aspect, because of stand density related to intraspecific competition.

ENC(Electronic Navigational Chart) is an electronic chart including all kinds of information of nautical chart. Mariners have difficulty reading information because of clutter problem if display scale of ECDIS is lower than compilation scale of ENCs. IRO made SCAMIN improvement model included in S-65 Standard to settle this ENC clutter problem. This SCAMIN model includes both simple restriction that should satisfy some requirement and share geographic information, and hard restriction that should overlap with area object such as depth area, land area, dredge area. It also apply SCAMIN step of sounding value according to importance of safety navigation. In this paper, we analyzed the restrictions for SCAMIN model of S-65 Standard, developed algorithm and application to apply theses restrictions reasonably and mechanically. Also we applied this algorithm and application to Korea ENCs and evaluated the result of performance.

The recent cultural properties utilization projects by the Cultural Heritage Administration have no rational standards to pay reasonable prices to stakeholders participating in budget compilation or projects. Therefore, there are frequent conflicts when calculating budgets between the Cultural Heritage Administration supervising projects and local governments or private organizations. Especially, as the items or detailed standard of budget compilation from planning to completion of projects are unclear, it is hard to stably operate projects, and eventually, they are no more than one-shot events without being developed into long-term projects. Thus, this study analyzes the overall operational status, systems, and problems of current cultural properties utilization projects. A national-level budget compilation standard system is then suggested, for the stable operation of cultural properties utilization projects. In addition, this study benchmarks the items and detailed standard of budget compilation used in similar areas, and also puts together actual cases.

The goal of this study is to investigate the relationship between maternal rearing behavior characteristics and elementary school children's Internet use, and to utilize the results as the basic data to develop a program, in which parents learn how to educate their children for better use of the Internet. The subjects were 713 children whose grade are in fourth through sixth in an elementary school. Data were obtained with questionnaires. The instruments employed were Children's Internet Use and Addiction, and maternal rearing behavior characteristics-Rational Guidance, Affection, Authoritarian Control, Overprotection, Achievement Encouragement, and Active Involvement-Scales. The data were analyzed with the SPSS program. They were analyzed by Frequency, Percentage, ANOVA, Duncan's test, and Pearson correlation. The results of this study are as follows: First, 30.2% of the subjects has used Internet for more than three years. 55.6% of the subjects spend less than an hour per day in using the Internet. The two major types of Internet use were playing games(49.9%) and sending e-mails(25.4%). The main reason for playing Internet games was escape from stress(34.7%). 34.5% of the subjects also said that their parents usually encourage them to use the Internet. Second, maternal affection, authoritarian control, and active involvement were significantly different in the types of Internet use. Maternal authoritarian control and overprotection were significantly different in the reasons of doing Internet game. The rational guidance and active involvement of mothers were correlated negatively with children's Internet using time, but their authoritarian control and overprotection were correlated positively with children's Internet using time. Maternal overprotection was correlated positively with parents' encouragement level in the Internet use. Third, the rational guidance, affection, and active involvement of mothers were correlated negatively with children's Internet addiction. In the other hand, maternal authoritarian control and overprotection were correlated positively with children's Internet addiction. Lastly, children's Internet addiction was significantly different by the types of Internet Use and the reasons for doing internet game. Children's Internet using time was correlated positively with children's Internet addiction.

Nutrient losses, especially nitrogen and phosphorus, in agricultural runoff can contaminate surface and ground water, leading to eutrophication. Thus, erosion control is crucial to minimizing nutrient losses from agricultural land. Assessments of various erosion control practices were carried out under various cropping system, soil management practices, and slope conditions by means of a lysimeter study and under artificial rainfall. Soil and nutrient losses were monitored in a small agricultural field to evaluate the soil conservation practices. Nutrient losses occur in runoff and leachate (dissolved nutrient) and in sediments (particulate nutrient). Dissolved nitrates accounted for the majority (about 90%) of nitrate transport within the soil. Particulate phosphate in sediments represented the majority (60% to 67%) of phosphate transport. Recently, engineering and agronomic erosion-control practices haver been used to reduce erosion problems in fields on slopes. These practices reduced soil loss, runoff, and nutrient loss to 1/6, 1/2,and 1/3 their original levels, respectively. Bioavailable particulate phosphate in sediments represents a variable but longterm source of phosphate for algae. Dissolved nitrate and phosphate are immediately available for algal uptake, so reducing fluxes of these nutrients should also reduce the risk of eutrophication.

Fires that result from the excessive leakage of gas due to earthquakes cause enormous loss of property as well as numerous human casualties. To prevent such disasters, an emergency gas shut-off system is considered to be one of the effective and rational methods. Considering the seismicity, the earthquake frequency and the gas-supply system of Korea, mass gas shut-off by a gas company is determined to be more cost-effective than individual gas shut-off by customers. In this study, an emergency response system was proposed that would shut off the gas supply immediately. Two different reference seismicities were proposed, to specify rapid response according to the measured seismicity. The gas supply area was divided into several gas shut-off blocks in order to facilitate the shut-off of gas supply in damaged blocks. This proposed system was implemented in the actual gas supply area with reference seismicities on the basis of seismic damage analysis.

Even though the similar land price zone is very important element in the public land appraisal procedure, the concept is implicitly described and applied into the actual land appraisal system. This situation makes it worse when applying for the automatic selection of a comparative standard land parcel. In addition, the division of similar land price zones requires the objective and reasonable process for improving ALPAS(Automatic land Price Appraisal System), which becomes an issue today. To solve the similar land price zone determination problem that is caused by the lack of objective numerical standard, this study proposed a similar land price zone determination method using a hybrid clustering technique. Results showed that this hybrid clustering method that applied into the test area could easily detect similar land price zones with considerable accuracy levels, which are verified with some test statistics and real comparative standard land parcels done by manually.

In these days, according to the enhancement of the mobile communication technologies, location based services using the location and movements are vitalized. In this paper, we develop a private vehicle tracking system for garbage truck operation management using GPS and CDMA communication and Open map interface. The terminal equipment attached in vehicle receives the GPS signals and detect the position data including time, longitude, latitude, and altitude. And the terminal sends these data to the server PC through CDMA cellular network in fixed period. The server saves these data into database to process in map server program with which we can view real-time trace of moving vehicle. We apply our system to public garbage truck managing operation and we can increase operation efficiency by examine real-time working and moving path and by present reasonable operation rout.
