There are various methods of proving a proposition. Among these, 'mathematical induction' is treated in school mathematics weightly. But many students have difficulty with the proof by 'mathematical induction'. To solve this problem, analysis needs to be attempted in various aspects This study attempts to compare the teaching methods of 'mathematical induction' in South and North Korea and to acquire the implication. In fact, many differences between South and North Korea are found. These differences are caused by epistemological and psychological premise. Therefore this study investigates the epistemological and psychological aspects in North Korea and compares the textbooks in South and North Korea. Through this study, some implications are found. First, the sequence of introducing the 'mathematical Induction' needs to be considered. Second, the rich context of applying the 'mathematical induction' is needed. Finally, disagreement between curriculum and textbook in South Korea needs to be reconsidered.

Does Foreign Direct Investment (FDI) exacerbate income inequality in South Korea? If so, does rising income inequality come for the sake of economic growth? This study explores the impact of FDI on income inequality and growth in South Korea. To this end, we collect data on FDI and income inequality/economic growth at both national and provincial levels and empirically test their relationships in South Korea. The empirical results confirm our expectation that FDI magnifies income inequality. Furthermore, we fail to find a positive relationship between FDI and economic growth, implying that income inequality as a consequence of FDI does not come for the sake of economic growth in Korea. Findings suggest that more systematic research and nuanced policy design is necessary to circumvent the mechanisms at play that link the surge of FDI inflows and the exponential expansion of economic inequality.

북한에서는 1990년대 이후 경제실패로 인해 대규모의 산림파괴가 이루어 진 것으로 알려져 있으며, 이는 결과적으로 수문순환의 특성을 크게 변화시켰을 것으로 예측되고 있다. 본 연구에서는 이를 확인하기 위해 지표수문해석모형인 VIC 모형을 이용하여 한반도 전역을 대상으로 1981년부터 2013년까지 약 30여년의 기간에 대해 수문순환모의를 수행하였다. 모의 결과를 요약하면 다음과 같다. 먼저, 유출률의 경우, 남한에서는 55%~70%, 북한에서는 38%~56% 정도인 것으로 나타났다. 특히 유출률 자체가 작음에도 불구하고 그 변동폭은 남한의 15% 보다 큰 28% 정도임에 주목할 필요가 있다. 증발산률은 북한이 남한보다 크게 나타났다. 즉, 남한에서는 증발산률이 20~35%, 북한에서는 25%~46%로 나타났다. 그러나 그 변동폭은 북한의 경우가 21%로 남한의 15%에 비해 다소 크게 나타났다. 셋째, 토양수분량의 경우 남한의 평균이 34%, 북한의 평균은 27%로 남한이 높은 것으로 나타났다. 그러나 유출률과 증발산률의 모의 결과와는 달리 토양수분은 전 기간에 걸쳐 남한과 북한이 변동성 차이가 8% 내외로 유사한 것으로 나타났다. 이상과 같은 결과를 통해 특히 북한의 산림파괴가 본격적으로 이루어진 1990년대 이후 남한과 북한의 수문순환 특성의 차이가 확대되었음을 확인할 수 있었다. 남한의 경우에는 유역별 수문순환 특성의 차이가 미미한데 비해, 북한의 경우에는 확연히 다른 차이를 보여주고 있는데, 이 역시 산림파괴의 영향 차이가 반영된 결과로 추측된다.

A recent nationwide survey reported that South Koreans perceive large corporations as the party that should be the most responsible for tackling climate change. This public opinion result offers insight into the argument that defining who is responsible for the climate change issue can guide campaigners and policymakers in designing effective communication strategies. This study examines how attributing responsibility to large corporations can affect behavioral intention to support government policy and regulation via a moderated mediation model of the perceived risk of climate change and corporate social responsibility (CSR). A nationwide online survey of 295 South Koreans was conducted. The findings reveal an indirect effect of responsibility attribution on behavioral intention through risk perception. Moreover, perceived CSR moderated the causal link between risk perception and behavioral intention, such that South Koreans reported higher levels of behavioral intention when they reported higher CSR. However, perceived CSR failed to moderate the indirect effect. These findings have implications for communication processes and policymaking to address climate change problems in South Korea.

Objectives : The aim of this study was to compare and analyze studies related to fire acupuncture (FA) published in South and North Korea. Methods : FA studies published in South Korea were searched through domestic and overseas databases (KISS, RISS, OASIS, and EMBASE). For North Korean studies, databases from the Information Center on North Korea and Korea Institute of Science and Technology Information were used. Among the searched literatures, clinical studies using FA as a treatment intervention were selected (i.e., randomized controlled trials, and case reports). Finally, information such as the disease for which FA was used, the characteristics of FA, and details of treatment methods for FA were extracted from the screened literatures and the results of South and North Korean studies were compared and analyzed. Results : This review included 28 South Korean studies and 9 North Korean studies. All studies in South Korea, except for the three articles that used traditional FA treatment, applied "warm needling"-like acupuncture (WA) in the form of heating the handle of the needle after inserting the needle into the skin, and most studies were conducted on diseases of the musculoskeletal system. Whereas in the North Korean studies, FA was applied to various diseases such as trigeminal neuralgia, skin diseases, and gastrointestinal diseases, and standardized FA tools were used. Conclusions : Studies on traditional FA treatment have rarely been reported in South Korea. The amount of information described in the FA studies in North Korea was limited. In this review, the characteristics of FA treatment tools in South and North Korean studies were mainly analyzed. In the future, FA studies from more diverse perspectives are needed.

Soil organic carbon (SOC) is a critical component of soil health and is crucial in mitigating climate change by sequestering carbon from the atmosphere. Accurate estimation of SOC storage is essential for understanding SOC dynamics and developing effective soil management strategies. This study aimed to investigate the factors influencing the spatial distribution of SOC storage in South Korea, using bulk density (BD) prediction to estimate SOC stock. The study utilized data from 393 soil series collected from various land uses across South Korea established by Korea Rural Development Administration from 1968-1999. The samples were analyzed for soil properties such as soil texture, pH, and BD, and SOC stock was estimated using a predictive model based on BD. The average SOC stock in South Korea at 30 cm topsoil was 49.1 Mg/ha. The study results revealed that soil texture and land use were the most significant factors influencing the spatial distribution of SOC storage in South Korea. Forested areas had significantly higher SOC storage than other land use types. Climate variables such as temperature and precipitation had a relative influence on SOC storage. The findings of this study provide valuable insights into the factors influencing the spatial distribution of SOC storage in South Korea.

In south Korea, the so-called 'conservative-liberal' rivalry over the assessment of the government's North Korean policies is seen to be impeding the road to right policy choices. For example, the liberals accused former President Lee Myung-bak's hardline policy of provoking Pyongyang and leading to a deterioration of inter-Korean relations, while the conservatives appreciated it for helping nurture mutually beneficial inter-Korean relations in the longer term by compelling North Korea to observe international norms. However, such debate over the vices and virtues of Seoul's North Korea policies is hardly meaningful as the measuring sticks used by the liberals and the conservatives are entirely different matters. The two major goals South Korea must pursue with its North Korean policies should be 'peaceful management of division' and 'change in North Korea'. The former is related to maintaining stability within South Korea and promoting co-prosperity with North Korea. For this, the nation needs to engage, encompass and assist the Pyongyang regime. The second goal is also necessary since South Korea, as a divided nation, must seek a unified Korea under the system of democracy and market economies by bringing change in North Korea. For this, South Korea needs powerful leverages with which it can persuade and coerce the North. This means that the nation is destined to simultaneously chase the above-mentioned two goals, while also both recognizing and negating the legitimacy of the North Korean regime. This situation necessitates Seoul to apply flexibility in reconciling with Pyongyang while applying firm principles to sever the vicious circle involving the North's military provocations. The May 25 Measures, which banned trade and economic cooperation with the North except those related to humanitarian assistance, were taken as sanctions against Pyongyang for sinking the South Korean corvette Chonan in March 2010. The Measures were taken by the Seoul government immediately after a multinational investigation team discovered evidence confirming that the South Korean naval ship had been torpedoed by a midget North Korean submarine. Naturally, the May 24 Measures have since then become a major stumbling block in inter-Korean exchange, prompting opposition politicians and concerned entrepreneurs to demand Seoul to unilaterally lift the Measures. Given the significant damages the Measures have inflicted on inter-Korean economic relations, removing them remains as homework for both Koreas. However, the Measures pertains to the 'principles on national security' the Seoul government must adhere to under all circumstances. This is why North Korea's apology and promises not to repeat similar provocations must come first. For now, South Korea has no alternative but to let North Korea solve the problems it has created. South Korea's role is to help the North do so.
