There are two main purposes in this study. First, we compare the effects of wives' characteristics with the effects of the husbands' characteristics on the induced abortion. Second, we analyze whether the determinants of the induced abortion have changed according to parity and conception period. The main findings are follows. First, both wives' and husbands' socioeconomic characters have insignificant effects on the induced abortion at parity 0, in the 1997 and 2000 Korean Fertility Survey data. Second, during the periods of the lowest-low fertility, after 2000 in Korea, wives' employments have positive effects at parity 0 and 1, while husbands' educational levels have negative effects at parity 1 on the induced abortion. The implications are as follows. First, having children had been the universal social phenomenon before 2000 in Korea. however, after 2000, reproductions have become the women's choice, lather than the duty of married women. Women must weight the balance between the benefits and the costs of children so that women's fertility behaviors become a rational choice. Women's employment is the most important factor in these rational calculations. Second, both Western individualism and the traditional Korean familism have significant effects on the fertility behavior and the induced abortions in Korea. This rejects the diffusion theory, which tells that the traditional familism must be replaced by the Western individualism in order to decline the fertility rates in developing countries.

In this paper, we estimate the investment cost for the IMT-2000 services in Korea. The network elements for the IMT-2000 system are drawn out and the required number of base stations(Node-B) is predicted by using the coverage of the base station. With the assumption of the 2-generation mobile communications network configuration, the number of radio network controllers(RNC's) and core network facilities is estimated. We also setup different scenarios by considering the utilization of the transmission facilities between base stations, RNC's and switching systems, and then evaluate the investment cost for each scenario.

In this paper, we designed and implemented the dual band antenna for IMT-2000 and 5.7㎓ WLAN(Wireless Local Area Network). The antenna was designed by using 3D simulations program, HFSS(High Frequency Structure Simulator). The electrical characteristics were measured by using HP 8720C network analyzer and measured maximum S$\sub$11/ was -25㏈, and maximum VSWR(Voltage Standing Wavc Ratio) was 1.26 for all frequency bands of interests in IMT-2000 and 5.7㎓ WLAN. Simulation results for antenna gain at 2㎓ and 5.7㎓ were 1.31㏈i and 4.1㏈i with omni directional radiation pattern. Implemented antenna is compact sized and can be produced in low cost enough for commercialization.

A 4-year joint research project (1999-2003), entitled "The Development of Multiple Talents (DMT)", has been designed and carrying out under the sponsorship of the National Science Council, R.O.C. (Taiwan). A 3-dimension construct is proposed for the DMT: form of talents (10 forms, mainly based on Gardner′s theory of multiple intelligences), function of talents (3 functions, based on Stemberg′s conception of successful intelligence), and developmental stage (4 stages, from pre-school to senior high). To take an example of its empirical studies, Wu and Chien (2000), based on a renovated conception of personal intelligence, developed the "Personal Intelligence Inventory" (PII). By means of the PII, it was found that there were some personal intelligence differences between gifted and regular pupils: however, gifted group was not as superior as on academic performance to the regular one (Wu '||'&'||' Chien, 2000). It was also found that there were significant relationships between pupils′personal intelligence and school adjustment in both groups (Tsai '||'&'||' Wu, 2000).

This study analyzed trends in agricultural and food marketing studies from 1984 to 2015 using text-mining techniques. Text-mining is a part of Big-data analysis, which is an effective tool to objectively process large amounts of information based on categorization and trend analysis. In the present study, frequency analysis, topic analysis and association rules were conducted. Titles of agricultural and food marketing studies in four journals and reports were used for placing the analysis. The results showed that 1,126 total theses related to agricultural and food marketing could be categorized into six subjects. There were significant changes in research trends before and after the 2000s. While research before 2000s focused on farm and wholesale level marketing, research after the 2000s mainly covered consumption, (processed)food, exports and imports. Local food and school meals are new subjects that are increasingly being studied. Issues regarding agricultural supply and demand were the only subjects investigated in policy research studies. Interest in agricultural supply and demand was lost after the 2000s. A number of studies after the 2010s analyzed consumption, primarily consumption trends and consumer behavior.

Since the recent Hanok boom in Korea, Contemporary Hanok has been evolving in terms of structure, space, form, etc. To get a comprehensive understanding of the diversified Contemporary Hanok, this paper aims at its type classification by analyzing architects' designs since 2000. The criteria for the classification are two: (1) renovation [Re] or new construction [New]; and (2) degree of Contemporary Hanok's deviation from the traditional Hanok's standard - maintaining the traditional form [Main]; changing space within the traditional form [Space]; changing the traditional frame [Frame]; and juxtaposing the traditional and the modern [Combi]. From the two criteria, this paper deduced eight types of Contemporary Hanok, named respectively: Re-Main, New-Main, Re-Space, New-Space, Re-Frame, New-Frame, Re-Combi, and New-Combi, and studied their cases. It can be argued that various aspects of Contemporary Hanok and their critical meanings were well-investigated through this type classification and case-studies.
