The purpose of this study was to compare characteristics between the parents who saved money for their children's college education and those who did not, in an effort to identify the factors influencing the decision to save. From 1998 Survey of Consumer Finances (SCF), a sample of 1,085 family households was employed. Logistic regression analysis was used to examine the probability of saving for college education. The results showed that higher incomes and financial assets significantly increased the probability of saving for children's college education. The married couples who had higher education and larger household sizes were more likely to save. The age of the youngest child was a significant positive factor in the probability of saving for college education

NCW(Network Centric Warfare) offers BSEs(Battelspace-Entities) the capabilities of sharing information through C4ISRCommand, Control, Communications, Computers and Intelligence, Surveillance and Reconnaissance) network and it also improves their combat powers based on information superiority with awareness of common situation in battlefield and self-synchronization. Although the concept of NCW was developed at the end of 1990 and there have been various studies for NCW from the development of its concept, the effort for measuring the synergistic effect of NCW is insufficient at the present time. Therefore, in this paper we reviewed literatures concerning the effectiveness measurement of NCW. The category of our survey is network effect, metrics, simulation, battlefield information, social network analysis and mathematical model. The main purpose of this study is to suggest future researchers a research direction by analyzing the aspects and limitations of existing studies about the quantitative measurement of NCW.

The advanced rural village development project started in 2005, and this project of purpose is improvement of housing environment and promotion of region activation. Researcher investigated about the advanced rural village development project of nine complex through field survey. The aim of this study is to be offered data of idyllic housing policy by examination actual conditions of study subject. Based on this study, mainly three results can be drawn as follows ; first, this project makes a great contributed to flow in population from urban to activate rural areas. Second, the project success depends on improvement an institution and planed, timely approach. Third, central government must plan network system with rural development project in political, and must support local government into political frame. The local government must consider a regional housing plan overall and must make an effort itself for the project success.

Purpose - This study aims to suggest appropriate policies and performance indicators for financial aid recipients. It analyzes the existing regular government policy funds support project, especially its propriety and reasonability. Research design, data, and methodology - When financial aid is effective, it should be able to predict small enterprise business results. Additionally, there should be an evaluation, checking before and after performance rates so that the rate of achievement and outcome can be measured. This study's contribution for small enterprises is in researching the best way to improve this support system. Results - The Small Enterprise and Market Service (SEMAS), currently designated as a support organization for implementing the government financial aid project, has assessment indicators. However, these focus mainly on quantitative indicators and survey results. Conclusions - In the future, there is some need to draw up measures, setting the right direction for developing policies for the small enterprise fund loans and improving the management of the plans. Eventually, this effort will dispel concerns about the present support policy, which is considered to be weakening small enterprises.

In this paper, attendance in distance learning courses of a cyber university has been surveyed in an effort to verify the effectiveness of distance learning. Based on survey data from 4,749 distance learning participants, major attending place, major reasons for attending online class, fidelity to online classes, attending time per week, perceived educational effectiveness, perceived and relative seriousness of problems, and other variables have been evaluated. The results indicate that perceptional seriousness of the investigated problems is not statistically important. The findings indicate that, among operational problems, self willingness and cheating are the most remarkable. In contrast, the relative seriousness of traditionally recognized problems such as H/W availability and network speed among environmental problems is least remarkable. An analysis of demographic differences such as sex, employment, and school year in terms of seriousness of problems is also performed. The results reveal the existence of statistically significant differences according to sex, employment, and school year with regard to almost all elements of environment, actual current conditions, and seriousness of problems, with the exception of some elements such as attending place and perceived fidelity.

In an effort to increase the operational efficiency of highways, South Korea has been increasing its design speed recently. However, the use of higher design speed will also increase construction costs. Moreover, increasing the design speed is expected to have an impact on safety. Hence, there is a strong need to demonstrate that the benefits outweigh the cost of having a higher design speed. This study surveyed a sample of design engineers to determine their awareness of the consequences of increasing design speed and their assessment of the right design speed for an actual rural arterial. In addition to the survey, a case study of three recently upgraded highways was conducted to determine the changes in traffic volumes, speeds, travel times, and safety.

In order to cope with improvement of labor cost and cargo volume, Korean ports, especially Busan port, are in need of many new facilities. Of course, current facilities should be fully used, and at the same time it needs to make every effort to maximize its productivity as well as cost saving. To this end, this study has decided to focus on automatic yard operation suitable to the domestic container terminal environments, making a survey of many advanced container terminals, trying to find out their common factors, and finally suggesting several alternatives based on the combination of these factors. Also, this study has suggested the present value of initial investment and operating cost by alternative, and at the same time presented the relationship between cargo handling volume and cost/revenue of the optimal alternative, so that it may be of help in decision making.

This paper aims to make a feasibility study and to propose a master plan for the development of "integrated ocean energy utilization system", which utilizes various renewable ocean energies. Fossils energy, as the most important energy resources which are inevitable for the living and industrial development, becomes exhausted and its consumption creates serious environmental problem. It is important to utilize renewable ocean energy for a sustainable and environmentally friendly development. We survey the integrated utilization of ocean energy based on surveyed energy density distribution and propose concepts of integrated ocean energy utilization plant for both onshore and offshore system. The results of this study can support national effort for renewable energy development utilizing integrated ocean energy and refer as a guideline for the technical development of sustainable integrated ocean energy.

There are so much oil and gas reserves in Iran. Therefore extraction from these reserves and sell extracted oil and gas in international markets causes to high oil income for Iran. Especially in some years which oil price increases, our oil income was too high. In this paper, we want to reveal that, high oil income is not cause to rise of nonoil export. For this aim, we use from data of 1971-2013 and with Johansen co-integration test and Error Correction Model (ECM) extract short run and long run relations. Results of estimation reveal that in Iran high oil income is not cause to many non oil exports in long run and short run. Therefore, we should allocate oil income to import industrial machines and reallocate them to agriculture and industrial sectors which causes to raise national production which will cause to high non oil export. Then, in this condition, our needy exchanges are provided from non oil export and our dependence to oil income will be declined.
