This paper introduces a politico-economic model with a welfare state and immigration. In this model, policies on taxes and immigration are determined through a plurality voting system. While many studies of fiscal implications of immigration argue that relaxing immigration policies can substitute for tax reforms in an aging economy, I show that the democratic voting procedure can dampen the effect of relaxing immigration policies as desired policy reforms are not always implemented by the winner of an election. This political economy results in three types of social welfare losses. First, the skill composition is not balanced at a socially efficient level because workers are motivated to maximize their wages. Second, older retirees implement excessive taxes to maximize the size of the welfare state. Third, the volume of immigration is lower than the optimal level given the incentive by young workers to regain political power in the future.

This study investigates the effect of economic factors on immigration using the gravity model of immigration. Cross-sectional regression and panel data analyses are conducted from 2000 to 2019 using the OECD International Migration Database, which consists of 36 destination countries and 201 countries of origin. The Poisson pseudo-maximum-likelihood method, which can effectively correct potential biased estimates caused by zeros in the immigration data, is used for estimation. The results indicate that the economic factors strengthened after the global financial crisis. Additionally, this effect varies depending on the type of immigration (the income level of origin country). The gravity model applied to immigration performs reasonably well, but it is necessary to consider the country-specific and time-varying characteristics.

The purpose of this study is to provide basic data for the establishment of the management plan of Seoullo 7017 after analyzing the characteristics of immigration plants in addition to those introduced plants. The taxa number of plants appeared as 276 taxa including 82 families, 161 genera, 246 species, 1 subspecies, 22 varieties and 7 forms. Among them, immigration plants appeared 79 classification groups, including 32 families, 65 genera, 77 species and 2 varieties. Invasive alien plants appeared as 22 classification groups in 79 classification groups of immigration plants. The ratio of America origin plants, second period(1932~1960) in introduction time and the wide diffusion species is high. In June, the growth and occurrence time of the immigration plants was the highest by monthly the characteristics of the growth of the immigration plants, the immigration plants appeared mostly. In case of dormancy form among life-form, the therophytes(th), in the propagation form-radicoid form, the R₅(monophyte), in the propagation form-disseminule form, the gravity D₄(having no special modification for dissemination), and in the growth form, the erect form(e) was high. The various immigration plants appeared in green areas covered by Zoysia japonica and low Hedera helix densities. This study is the first flora study since Seoullo 7017 was opened in 2017. And so continuous flora monitoring is required for Seoullo 7017.

This paper intends to examine the extent of the fiscal contribution of immigrants to Korea. According to this analysis, the aim is to derive implications pertaining to the direction of Korea's immigration policy as a response to fiscal problems caused by population aging. For this purpose, a macroeconomic model is designed to measure the lifetime net fiscal contribution of immigrants in Korea by visa type, age, and other characteristics. According to this analysis, the sum of the lifetime fiscal contribution for all immigrants in Korea is negative. This implies that immigration policy reforms that increase the inflow size while maintaining the current structure of the foreign population characteristics can rather worsen Korea's fiscal problems. This finding suggests that immigration policy reform may exacerbate Korea's fiscal soundness if it simply targets the maintenance of the numerical balance of the demographic structure.

기존 공항이용객들은 공항의 입출국시 출입국 심사관에게 직접 여권을 제시하여 출입국 심사를 받아왔다. 이런 기존 출입국 심사제도의 비효율성을 개선하기 위하여 인천국제공항은 자동출입국심사제도를 도입하여 공항이용객들이 간편하게 출입국 심사를 받을 수 있게 하고 있다. 본 연구는 인천국제공항의 자동출입국심사 시스템의 사용의도에 영향을 미치는 변수를 파악하고, 이들 변수가 자동출입국심사 시스템의 지속적 사용의도에 어떠한 영향을 미치는 지를 파악하는데 그 목적이 있다. 자동출입국심사 시스템의 사용의도를 파악하기 위하여 기술수용모형(Technology Acceptance Model)를 토대로 한 연구모형을 개발하였고, 구조방정식을 사용하여 중요변수들 간의 관계를 파악하고자 한다. 본 연구의 결과는 향후 자동출입국심사 시스템 사용인원의 증가를 위한 전략제시와 자동출입국심사 시스템의 개선을 위한 기초자료로 활용할 수 있을 것이다.

A convenience samples of Korean-Canadian/American adults who lived in Vancouver, San Hose and Los Angeles areas for over 10 years, were studied in 2000. Total of 130 adults were analyzed by immigration age. The age of immigration age was divided into 3 groups: the young group immigrated at 25 or before, the middle group immigrated at 26 to 40, and the old group immigrated at over 40. Their average length of residence in Canada and the U.S. was a little longer than 20 years. The dietary behavior patterns were similar among 3 groups, except co-eaters and dining-out frequency, and the Korean-Canadians/Americans seemed to be more home-based, family-tightened and traditional patterns than Koreans in Korea. They liked Korean traditional basic dishes, but their children liked a-la-carte ones and immigrants at early 20's showed similar food preferences as young generations. The attitudes of dietary acculturation for themselves and for their children were high. Since immigrating at age 26 to 40 years old rather than 20's or over 40's, showed stronger acculturation attitudes even with no significance and revealed significantly differences in some dietary behaviors and food preferences, it is recommended that immigration age should be considered when planning dietary foodservices at nursing care systems for Korean Canadians/Americans.

The objectives of this study were to study multicultural society of rural areas in Korea. USA immigration law permits permanent settlement but Korea immigration law prohibits permanent settlement. USA adopted the territorial principle but Korea adopted the personal(nationality) principle. So a large number of people immigrated and settled in USA and mass(collective) immigrants is usual in USA. But foreign workers(temporary immigration) and international marriage women(individual immigrants) is usual in Korea. According to the positive law, foreign workers cannot settle down in Korea. So international marriage women immigrants are main cause of multicultural society in rural areas in Korea. This is the particularity of multicultural society in rural areas in Korea. So it is necessary to differentiate multicultural society policy according to areas and residents. Many peoples see multicultural society from a point of view of human rights and welfare. But it is also necessary to see multicultural society from a point of view of economic and policy.

In science and engineering programs in the U.S. in 2000 China, South Korea and India were top countries of origin sending students. More than half of the students intend to stay in the U.S. Immigration, education and occupational choices all have human capital aspects that require investments. A framework is proposed where expected incomes in both countries of origin and destination are calculated and used to reflect the substitution effect and the wealth effects of the expected incomes of two countries. It appears that nonpecuniary effects of education encourages immigration as much as pecuniary effects in the immigration decision equation. After the pecuniary effects are accounted for there is some negative nonpecuniary tendency of the professional scientists to immigrate to the U.S.

이 연구는 다양한 문화적 분화도를 보이는 OECD 회원국을 대상으로 객관적 지표를 이용해 각국 이민자의 사회통합을 1)선주민과 비교한 상대적 기준과 2)이민자의 복지수준을 고려한 절대적 기준에서 비교분석하려는 목적으로 이루어졌다. 복수의 국제 데이터를 통합한 2차 데이터를 이용했으며 주요 변수 사이의 산점도를 산출하여 이민자 사회통합의 국가별 지형을 분석했다. 분석결과에 의하면, 상대적 기준의 사회통합은 전통적 이민국 레짐에 해당하는 호주, 캐나다, 미국이 이상적인 국가들로 나타났다. 절대적 기준의 사회통합이 높은 국가는 전통적 이민국 레짐과 적극적 이민국 레짐이 혼합된 형태를 보였다. 상대적 기준과 절대적 기준 모두에서 이민자의 사회통합 수준이 비교적 높은 국가는 전통적 이민국 레짐과 아일랜드, 포르투칼, 슬로베니아 등 일부 신이민국 레짐에 속한 국가들로 나타났다. 이와 같은 결과는 이민자의 사회통합은 이민국 레짐으로 대표되는 이민정책이나 문화적 분화도를 통해 설명할 수 있는 부분은 제한적이며, 이민자의 사회통합은 개별국가의 사회보장정책 등을 함께 고려해 이해되어야 함을 시사했다.
