Before the 1960s, North Korea's GDP per capita was 30%-50% higher than South Korea's due to industrialisation during the 1930s. However, the governments of the two Koreas pursued different goals in the 1960s, which resulted in a reversal. The South Korean government made economic growth its ultimate goal. They did this by self-implementing, adjusting and instituting an export-oriented development strategy. On the other hand, the North Korean government tried to maximise its ability to survive by sacrificing gains from economies of scale. These differences brought about remarkable differences in economic performance. The gap between the two economies has continued to grow since the income level reversal in the 1970s.

The stamp is “an arena for conveying every possible kind of message through pictures”. Since stamp motives are not chosen arbitrarily, this study considers what stamps issued by North and South Korea since their foundation in 1948 tell about these states. Firstly, the number of stamps made by each state from 1948 until 2002 is investigated. This time is divided into ten-year periods. Conclusions are drawn from the number of stamps made. Secondly, the motives are investigated in detail. Eight motives—commemoratives, history, famous persons, culture, politics, economics, nature and miscellaneous are identified. Quantitative data on the motives are presented in tables that are followed by facts about the issues. Thirdly, the main findings are presented on a general level and under the motives identified. Implications of the motives on North and South Korean stamps are discussed and similarities and differences are highlighted.

A cross-sectional twin design was used to study the developmental nature of genetic and environmental influences on morningness-eveningness (M-E). A total of 977 South Korean twin pairs aged 9-23 years completed 13 items of a Korean version of the Composite Scale through the telephone interview. The total sample was split into three age groups: preadolescents, adolescents, and young adults. Twin correlations did not vary significantly with age, suggesting that genetic influences on M-E are stable throughout the developmental span. Results of model-fitting analyses indicated that genetic and environmental factors explained, respectively, 45% and 55% of the variance in all three age groups. Environmental factors were primarily those factors that twins did not share as a consequence of their common rearing; family environmental factors in M-E were consistently near zero in all three age groups. The present study is the first to demonstrate genetic influences on M-E in preadolescent children as young as 9 years old. In spite of differences in culture and frequencies of genes between South Koreans and Caucasians, genetic and environmental influences on M-E found in the present sample were remarkably similar to those reported by previous studies on the basis of late adolescent and adult Caucasian twins.

Purpose - The purpose of this article is to assess the spread of internet use and the pay-per-use system. Design/methodology/approach - Presents the active debate with regard to "pay-per-use" for internet access, and pays particular consideration to the progress and propects of pay-per-use in Korea. Findings - Although the trend is towards a pay-per-use system, the Korean Government has concerns about a pay-per-use system. Originality/value - Indicates that transformation into pay-per-use will require a dramatic revolution and a change in the internet service indudustry.

? Arachnological Society of Japan.The spider species name Pelecopsis montana Seo 2018 (Linyphiidae) is preoccupied and re-quires a replacement name. We establish herein the necessary replacement nomen, namely: Pelecopsis seoi nom. nov. The homonymy of the recently synonymized genus name Collis Seo 2018 (Linyphiidae) and the possible homonymy of Hahnia montana Seo 2017 (Hahniidae) in the near future are also briefly discussed.

For the past 60

The sand dunes in coastal regions of South Korea are important ecosystems because of their small size, the rare species found in this habitat, and the beautiful landscapes they create. This study investigated the current vegetative status of sand dunes on three representative coasts of the Korean peninsula, and on the coasts of Cheju Island, and assessed the conditions caused by invasive plants. The relationships between the degree of invasion and 14 environmental variables were studied. Plots of sand dunes along line transects perpendicular to the coastal lines were established to estimate vegetative species coverage. TWINSPAN (Two-Way Indicator Species Analysis), CCA (Canonical Correspondence Analysis), and DCCA (Detrended Canonical Correspondence Analysis) were performed to classify communities on sand dunes and assess species composition variation. Carex kobomugi, Etymus mollis, and Vitex rotundifolia were found to be the dominant species plotted on the east, the west, and the peripheral coasts of Cheju Island, respectively. Vegetation on the south coast was totally extinct. The 19 communities, including representative C. kohomugi, C. kobomugi-Ixeris repens, C. kobomugi-Oenothera biennis, E. mollis, Lolium multiflorum-Calystegia soldanella, and V. rotundifolia-C. kobomugi, were all classified according to TWINSPAN. Oenothera biennis and L. multiflorum were exotics observed within these native communities. CCA showed that invasive native and exotic species distribution was segregated significantly, according to disturbance level, exotic species number, gravel, sand and silt contents, as well as vegetation size. It further revealed that human disturbance can strongly favor the settlement of invasive and exotic species. Restoration options to reduce exotic plants in the South Korean sand dune areas were found to be the introduction of native plant species from one sand dune into other sand dune areas, prohibition of building and the introduction of exotic soils, and conservation of surrounding sand dune areas.

Korean species of the crane fly genus Rhipidia Meigen, 1818 (Diptera: Limoniidae), are taxonomically revised. Rhipidia (Rhipidia) serena, new species, is described and figured. Rhipidia (R.) longa Zhang, Li, Yang, 2014, R. (R.) maculata Meigen, 1818 and R. (R.) sejuga Zhang, Li, Yang, 2014 are recorded for the first time in Korea. Previously known species, Rhipidia (R.) septentrionis Alexander, 1913 is redescribed and illustrated. Identification key for all Korean Rhipidia species is given. Most antennae, wings, male and female terminalia of all species are illustrated for the first time.

This paper proves theoretically that bilateral trade between South and North Korea, between whom many political barriers to trade exist, is Pareto‐inefficient, and that a Pareto‐efficient situation can be achieved through the attainment of institutional economic integration, enabled by mutual agreement between South and North Korea. Based on our theoretical analysis, we propose a comprehensive economic integration agreement as an instrumental framework for the gradual integration of South and North Korea. In addition, we analyze the economic impacts of such integration. We estimate that gradual integration would positively affect North Korean GDP, increasing it by 3.55–4.88 percent from the baseline, depending on the various scenarios we analyze.

South Korea and Japan have experienced their worst deterioration of bilateral relations since 2012. What are the long-term prospects for this relationship? Will it continue on this negative trajectory or recover positively in the long term? Challenging the conventional view that supports the former conclusion, this paper argues for a positive outlook for the relationship in the long term. This is defended from a structural perspective relying on two long-term strategic trends for Northeast/ East Asia-the elevated uncertainty in the regional environment (due to North Korea and China's strategic rise); and the rising strain on the U.S. military presence in both countries. In response to these structural pressures, South Korea and Japan will adapt and adopt strategies to defend their national security within a reformed U.S. alliance structure and strengthen strategic cooperation through bilateral and trilateral (with the United States) means.
