This study scrutinizes the necessity and cases of the public and pension cooperation and tries to present the way of construction of information infrastructure for the pension systems suitable for Korea. The developed countries have recently been focusing on strengthening the multi-pillar pension system, while pension education and information services have emerged as an important element of the pension cooperation. The frame of the multi-pillar-pension system in Korea has already been constructed, but it is not substantial. Especially bad information on the pension system has seriously hindered the consolidation of the pension system. In order to solve this problem, we analyzed cases of public-private cooperation systems in Iceland, New Zealand, Netherlands, and Sweden. In order to build a basic infrastructure for construction pension cooperation in Korea, it is necessary to promote information exchange and cooperation among pension organizations and to improve the pension portal of NPS 'My Pension'. In addition, this study suggests establishing an association of private and public pension schemes, which manages the integrated information and education of pension systems.

Purpose: The purpose of this study was to investigate metaphors on free semester of special schools of the special education teachers, to categorize the metaphors and then, to explore differences according to variables of special education teachers. Method: 123 special education teachers described the metaphoric meaning on free semester of special schools and the ground using open-ended questions. The collected data were analyzed through four steps: coding, metaphor classification, category development and subject naming, validity and reliability review, and quantitative analysis. Results: First, the metaphors were categorized by 4 subjects such as 'journey for my dream', 'routines not different yesterday', 'object of study', and 'far-off hope'. Second, there were statistically significant differences on recognition on subjects according to teacher training experiences of special education teachers. In particular, the teachers who have experienced on teacher trainings thought of free semester as journey for my dream while the teachers who have not experienced on teacher trainings thought of it as 'object of study' Conclusion: Based on these results, the practical approaches to implement the ideal free semester of special schools were suggested.

In accordance with the global age, countries in the world try to dedicate to collaboration among them through ODA (Official Development Assistance), in order to solve the-rich-get-richer and the poor-get-poorer problems among countries, to develop the developing countries' economies, and to improve their level of social welfare. Also, Korea is so active in ODA as a member of OECD, even if it is in the initial process. Nowadays, in Korea, the importance of ODA in the field of port has been brought into relief. Accordingly, the paper intends to analyze the dilemma structure of port ODA from the perspectives both of new institutionalism and Samaritan's dilemma game, and it tries to seek the improvements of ODA institutions to create effective outcomes based on the analysis. Through the analysis, dilemma structure was identified regarding the institutions of port ODA. And the results of the analysis suggested the improvements of port ODA institutions including strengthening of on-the-spot aid system, establishment of payoffs system for inducing recipient countries' efforts, and institutionalization of reliable threat. It would contribute to develop the theoretical model of ODA analysis and create effective outcomes of ODA in the field of ports.

This study aims to examine the suggestions by studies that family predictors are related to developmental outcomes more strongly for children reared principally by their parents compared to those with extensive child care experience. Zero-order correlations between family predictors and developmental outcomes were conducted and the significance of differences in correlation coefficients between the two child care groups were examined. There was no evidence that there exist systematic differences between the two groups in predictive power of family factors except a few exceptions. At 2 years, social parenting style was more strongly associated with communication ability in the extensive child care group. At 3 years, some HOME subscales were related to a child's expressive and receptive vocabulary skills in significantly greater magnitudes in the mother care group. The findings also implied the potential contribution of child care environment on developmental outcomes for those who spend extensive hours in nonmaternal care.

The objective of the paper was to estimate the changes in acreages of tidal flats after the seawall construction at the Asan Bay and the Chunsu Bay from topographic maps, hydrographic charts, and Landsat TM images. The tidal floats from topographic maps published in one year differ significantly from that in the other, which appears to be attributed to the tide levels at the time of photographing. The hydrographic charts showed that tidal flats increase at rates of 22.3 ha/yr at the Asan Bay and 56.6 ha/yr at the Chunsu Bay after the dike construction. Applying the ISODATA method of unsupervised classifications for the Landsat TM images, the tidal flats were identified, and the resulting acreages for each image estimated. The resulting tidal flats increased at the rates of 21.3 ha/yr at the Asan Bay and 47.3 ha/yr at the Chunsu Bay during twelve years after the dike construction. It was found that the rates of the annual increases from the two data are very close and the differences result from the coastal lines at the charts and the TM images.

The stagnation of unsold houses is recently aggravated due to domestic and overseas crisis of finance and real-sector economy and domestic housing construction is in serious difficulty. Thus, tax support is necessary for national housing construction. Due to the current tax exemption system of national housing, V.A.T. paid in the construction of national housing is not deducted. Namely, it is ascribed to consumer as it is reflected in the construction cost. This research intends to analyze the limit of V.A.T. tax exemption system, to present the necessity of applying zero rate and to calculate the scale of non-deduction of V.A.T. purchase tax amount for national housing by analyzing the construction site of apartment house of house constructor in order to analyze the effect of zero rate when it is applied on the basis of above ground. In the zero rate system, V.A.T. is not collected from the consumers like the present tax exemption system. However, the purchase tax amount borne in the construction of national housing is deducted totally. As purchase tax is deducted, constructor will promote supplying national housing thanks to the effect of solving financial difficulties and improving liquidity. Since the architecture cost and parceling-out price can be lowered due to the improved liquidity of constructor, the policy will actually help the people without house.

The recent bridge construction projects demand thorough and systematic safety and risk management, due to the increase of risk factors following the introduction of new and complex construction methods and technologies. Among many types of damages that can occur in bridge construction projects, the damages to third parties who are not directly related to the existing property of the contractor construction project can also bring about critical loss in the project in order to compensate the damages. Therefore, risks that could be caused by the loss occurred to indemnify the third party damages should be clearly analyzed, although there are not subsequent amount of studies focusing on the issue. Based on the past record of insurance payment from domestic insurance companies for bridge construction projects, this study aimed to analyze the risk factors of bridge construction for loss caused to compensate the third-party damages happened in actual bridge construction projects and to develop a quantified and numerical predictive loss model. In order to develop the model, the loss ratio was selected as the dependent variable; and among many analyzed independent variables, the superstructure, foundation, flood, and ranking of contractors were the four significant risk factor variables that affect the loss ratio. The results produced can be used as an essential guidance for balanced risk assessment, supplementing the existing analysis on material losses in bridge construction projects by taking into account the third-party damage and losses.

Eight cation or anion-responsive polymer membranes were prepared by a casting procedure employing polyvinyl chloride, Bis (2-ethylhexyl)sebacate and each electroactive material in the ratio of 66 : 33 : 1. The resulting membranes were separately installed onto the sensitive area of the ionic electrodes to produce an 8-channel taste sensor array. The taste sensors of the array were connected to a high-input impedance amplifier and the amplified sensor signals were interfaced to a PC via an A/D converter. The taste evaluation system was applied to a discriminant analysis on six groups of marketed beverages like sikhye, sujunggwa, tangerine juice, ume juice, ionic drink and green tea. When the signal data from the sensor array were analyzed by principal component analysis after normalization, the 1st, 2nd and 3rd principal component explained most of the total data variance. The six groups of the analyzed beverages were discriminated well in the three dimensional principal component space. The half of the five groups of the analyzed beverages was also discriminated in the two dimensional principal component plane.

Traditionally, foreign labor inflow into Korea has been rare and, hence, issues on foreign workers did not draw much attention. However, changing economic conditions of the Korean economy, such as "labor-shortage" problem in SMEs in manufacturing sector, has made the Korean government open its door to the foreign workers since the early 1990s through the Industrial Trainee System. The inflow of foreign workers, on the other hand, has generated various social and economic problems, such as substantial increase of illegal over-stayers, illegal utilization of foreign unskilled workers by domestic SMEs, to name a few. Against this background, the Employment Permit System was implemented from 2004. This new system aims at supplying foreign workers to SMEs as well as protecting them as legal 'employees'. In any case, it is very important to understand how and to what extent the inflow of foreign workers have affected the Korean economy in order to establish long-term policy stance. This paper aims to empirically assess the economic impact of foreign workers on domestic workers in the manufacturing sector during 1997~20001, focusing on the Industrial Trainee System. The empirical results of the paper can be summarized as follows. First, there is some evidence that male semi-skilled workers are the group that is likely to have been displaced by industrial trainees. Second, we were unable to find any strong evidence suggesting that the inflow of foreign industrial trainees decreased wages of less-skilled Korean workers.
