ABSTRACT The purposes of this study were to investigate the structure, use and condition of the agricultural distance learning technology system, to identify the barriers in use, and finally to put forward some implications for future system construction. In order to achieve the purposes, two methodologies were adopted. One was review of literature, and the other was simulation test using alternative conferencing systems constructed by the researchers. It was revealed from the results of the study that ISDN was inappropriate network for the future and lack of multimedia database was the problem for current use. In terms of future system development and construction, three implications were made. The first was a conversion from site-built system to desktop system. Secondly, various network systems should be used. Lastly, the distance learning technology system should be constructed based on Internet platform as the trend of conferencing system is integrated in the Internet environment.

This paper was designed to synthesize quantitatively the master's theses and doctoral dissertations focusing on effects of family background traits related variables on academic achievements in Korean. This task was accomplished by utilizing the meta-analysis technique of research integration as defined by Glass(1982). Basically, meta-analysis is a statistical analysis of the summary findings of many empirical studies. Its purpose is to draw reliable and general conclusions form a large and complex body of literature on a common topic. Thus, the primary purpose of this paper was to conduct a quantitative synthesis of 96 master's theses and doctoral dissertations focusing on the effects of academic achievements using family background traits as independent variable and academic achievement as dependent variable. Nine independent variable were chosen by means of in depth review of those previously mentioned 96 studies. The independent variables employed in this study include psychologcal environment, physical environment, family structure, public and private educational expenditures, education process, breeding and education method of parents, socio-economic status, parents' characteristics, and role expectation. These variable are cartegorized by two different groups according to the traits of factors in terms of family environment variable group and parent's characteristics variable group. This study set the following questions to be answered: (1) How large are the grand average effect size of variables of family background traits proposed in this study on student's academic achievement?; (2) How different the effect size of the two family background traits related variable groups, naimly family environment and parents characteristics variable group on student's academic achievement?; and, (3) How different the effect size of the nine family background traits related independent variables on student's academic achievement? In order to answer the research questions, the researcher followed the standard procedures as such locating published studies to collect primary data, analysing and cording the characteristics and outcomes of the studies, and carring out statistical procedures of mata-analysis to describe the overall and sub-variable effects. Primary source of data was decided to limit within the master's these and doctoral dissertations in order to achieve the reliability and validity of the study results. By using the CD-ROM titled 'masterㆍdoctoral dissertation index' published by National Central Library in 1995 and 1997, a total of 112 studies were located and collected. Out of 112 studies, 96 studies were selected by excluding those studies that are not possible to employ mata-analysis such as studies used qualitative research method. While classifying family background traits related variables some of studies were also excluded in this study due to failing a consensus among the five specialists participated in this process. The effect size were calculated by using two different approaches depending upon the applicability of effect size formula. One was by using mean and standard deviation of experimental group and their countpart. The other was using transformational formula suggested by Wolf(1986) for the studies that have not presented descriptive statistics. The result of this study may be summarized as follows: (1) The grand average degree of effects of the academic achievement factors proposed in this study turned out to be .33. This means that if the average size of effects of the academic achievement factors of the controlled group is 50 percentile in normal distribution, that of the experimental group becomes 62.93 percentile. As it were, the latter surpass the former by 12.94 percentile. (2) Between the two groups of academic achievement factors proposed in this study, in terms of family environment variable group and parent's characteristics variable group, the former factors showed the higher average effect size, its average effect size being .35. Considering the grand average degree of effects size of .33,it can be suggested that those family environment related variables effects more on the student's academic achievement compare to the variables of parents' characteristics. Among the nine family background traits related independent variables on academic achievements proposed in this study, the variable of educational process showed the highest average effect size of 1.40, as followed by socio-economic status(effect size of 0.55),role expectation(effect size of 0.48), and physical environment(effect size of 0.40). The effect size of these variables turned out to be bigger that the grand average effect size of .33. This result means that these variable effects on student's academic achievement a lot more compare to other variable proposes in this study. In fact, the effect size of those variable such as phychologcal environment(effect size of 0.27), breeding and educational method of parents(effect size of 0.27), family structure(effect size of 0.26), public and private educational expenditures(effect size of 0.26), and parents' characteristics(effect size of 0.14) turned out to be much smaller than that of previously mentioned variables. It means that the variable of psychologcal environment, breeding and education method of parents, family structure, public and private educational expenditures, and parents' characteristics effect less on student's academic achievement compare to the variables of educational process, socio-economic status, role expectation, and physical environment.

DTM(Digital Terrain Model) can play a key rule in a great number of the fields of construction Engineering. One of the most important application fields is to determine volume in that the total construction expenses is usually calculated through this. It therefore is necessary to the study on improving the precise of the determination using DTM on account of saving time and cost. On this study, 1:5000 topographic maos issued by NGI in 15 districts involved in Pusan city was digitalized to generate DTM at first. After this step, not only was the determination of the volume as well as readjusted area and height done for the sake of estimating the changable topography caused by cut & fill volume in future but also provided the model to calculate it as results. In addition, comparison among the interpolations, such as Inverse Distance Method and Nearest Neighbor, was respectively done to look over the differences of the volume estimated from each interpolation and also to find the most suitable method. As a result, the former yielded the largest values of area and the volume while the latter gave the smallest ones. Moreover, the values estimated on this study were closely similar to ones obtained by the government of Pusan.
