This study aims to examine the change of state-market-family as three welfare provisions. This exploratory study investigates the change of welfare provisions and life of the elderly for 25 North Korean refugees focusing the actual condition of income security for the elderly using the snowball sampling. The main results are followings. First, in the age of Kim Il Sung showed the state-led, market absence, family supplementation and in the age of Kim Jong Il and Kim Jong Un showed the state diminishment, market appearance, family supplementation in terms of welfare provisions. Second, there is disparity between institution and reality because the law don't prescribe the responsibility of market provisions for the people but the elderly should have made a living in the market since the early 1990s. The situation of 'the weaken state and strengthened market' in the age of Kim Jong Il have still continued in the age of Kim Jong Un. The formal income security for the elderly need to return to the former condition.

이 연구는 북한지역의 풍력 자원을 조사하기 위한 사전 연구로 30년간의 북한 지역의 27개 지상 관측소의 풍속 (고도 10 m)을 수집하였다. 이 풍속을 고도 50 m로 환산하였으며, 풍속의 확률밀도함수를 Weibull 함수로 가정하여 분석하였다. 30년 동안의 지상 관측 자료를 바탕으로 볼 때, 대체적으로 황해도 해안지역과 개마고원지역에서 평균 풍속이 북한 전역에서의 평균 풍속 4.0 m/s 보다 큰 지역이 나타났다. 따라서, 해안지역에서 바람 자원이 풍부함을 알 수 있었다. 지역의 차이는 있으나, 봄철 동안의 주풍은 북서풍과 남풍계열이 대등하게 나타나고 있으며, 여름은 남풍계열의 바람이 주풍으로 변하며, 가을과 겨울 동안 북서풍 계열이 주된 바람이었다. 고도 80 m 에서 풍속이 5 m/s 이상 지속되는 기간이 연간 30% 이상인 주요 6지점 중 장진을 제외한 나머지 네 곳은 해안에 위치함을 알 수 있다. 북한 지역 내륙의 중심부인 장진에서 연간 평균풍속 4.7 m/s 이상으로 관측 되었다. 이 지역은 개마고원 일대로 낭림산맥과 함경산맥의 두줄기가 만나는 곳으로 산맥에 의해 뒤쪽이 막혀있어 바람이 집중되어 높은 풍속을 나타낸 것으로 보인다. 또한 이 지역은 고원지대에 위치하여 북쪽에서 고도 1 km 이상에서 강하게 불어오는 북서풍의 영향으로 풍속이 높게 나타나는 것으로 보인다. 이 연구에서 사용한 관측자료는 단순히 지상의 풍속과 풍력으로만 분석한 것이므로 몇 가지 제약성을 가지고 있어 추후 보강이 필요하다. 관측지점의 지리적 위치나 주변의 환경에 따라 풍황의 변화가 크게 달라질 수 있으므로, 북한의 지형적인 요인을 고려한 정확한 실측을 통해 정확도를 높이는 풍력 자원 조사가 뒷받침 되어야 한다. 이 연구의 가치는 30년간의 바람 자료를 이용하였기 때문에 북한 지역에서의 풍황을 보는데 중요한 정성적 자료로 쓰여질 수 있으리라 본다. 또한, 이 자료를 바탕으로 풍력에너지 발전의 후보지 선정에 유용하게 활용되기를 기대하며, 더 나아가 두 나라 간에 에너지 교류가 활발히 이루어지기를 바란다.

The wave of democratization that started in southern Europe spread to South America and Asia, dismantling the Soviet Union and Eastern European countries and appeared as a Jasmine revolution in countries of North Africa and the Middle East. As a result, many scholars have actively carried out researches related to the sudden change of North Korea, while taking a cautious view that the Jasmine Revolution might occur in North Korea. The focuses of the studies were on the cause and timing of the sudden change and the main forces of the revolution in North Korea. There weren't enough discussions on how the process will be developed and whether there will be a system change. In this study, based on the results of analyzing the systematic changes of the Jasmine revolution nations, it suggested five scenarios that can be developed after the sudden change of North Korea. Scenario type I: Relatively peaceful and the possibility of regime change, Scenario type II: Reunification and then civil war, Scenario type III: Regime changed but one of Kim Il Sung family grabbing the power, Scenario type IV: Successful regime change but civil war happening, Scenario type V: Regime change failed and civil war continuing.

The failure of early economic sanctions aimed at hurting the overall economies of targeted states called for a more sophisticated design of economic sanctions. This paved way for the advent of 'smart sanctions,' which target the supporters of the regime instead of the public mass. Despite controversies over the effectiveness of economic sanctions as a coercive tool to change the behavior of a targeted state, the transformation from 'comprehensive sanctions' to 'smart sanctions' is gaining the status of a legitimate method to impose punishment on states that do not conform to international norms, the nonproliferation of weapons of mass destruction in this particular context of the paper. The five permanent members of the United Nations Security Council proved that it can come to an accord on imposing economic sanctions over adopting resolutions on waging military war with targeted states. The North Korean nuclear issue has been the biggest security threat to countries in the region, even for China out of fear that further developments of nuclear weapons in North Korea might lead to a 'domino-effect,' leading to nuclear proliferation in the Northeast Asia region. Economic sanctions had been adopted by the UNSC as early as 2006 after the first North Korean nuclear test and has continually strengthened sanctions measures at each stage of North Korean weapons development. While dubious of the effectiveness of early sanctions on North Korea, recent sanctions that limit North Korea's exports of coal and imports of oil seem to have an impact on the regime, inducing Kim Jong-un to commit to peaceful talks since 2018. The purpose of this paper is to add a variable to the factors determining the success of economic sanctions on North Korea: preventing North Korea's evasion efforts by conducting illegal transshipments at sea. I first analyze the cause of recent success in the economic sanctions that led Kim Jong-un to engage in talks and add the maritime element to the argument. There are three conditions for the success of the sanctions regime, and they are: (1) smart sanctions, targeting commodities and support groups (elites) vital to regime survival., (2) China's faithful participation in the sanctions regime, and finally, (3) preventing North Korea's maritime evasion efforts.

After the liberation of Korea from Japanese colonialism, archeology in South and North Korea took different paths. In particular, archeology in South and North Korea began to show great differences from the 1970s, when the former experienced rapid academic advancement following the evacuation of large-scale relics and the latter began to demonstrate a drastically political nature. North Korea declared 'Daedonggang Culture' in the 1990s, and South and North Korean archeology subsequently became so divorced that the two shared almost no common ideas. This kind of discrepancy is now particularly prominent with regard to the Bronze Age and Iron Age around "Gojoseon". Researchers of prehistoric archeology in South Korea have no choice but to keep referring to North Korean archeology. This is because North Korean resources are the main research subjects for identifying "the origin and descent of culture", which is still one of the most important research topics. However, people cast doubt on their reliability. Such a "two-fold viewpoint" demonstrates how those associated with South Korean archeology perceive their counterparts in North Korea. A large part of the visible "gap" between South and North Korea in terms of Bronze Age archeology comes from "political difference" that cannot be resolved by an increase in survey cases or academic debate. However, examining the trend in prehistoric archeology in North Korea is not aimed at criticizing the political nature of North Korean archeology. The goal is to investigate how the North Korean perspective on the Bronze Age differs from that in South Korea at present and to examine the potential problems in explaining "prehistoric culture in the Korean peninsula" and, furthermore, prehistoric culture in Northeast Asia, by including North Korean resources. This paper examines how Bronze Age-related research trends have evolved in North Korea to date and compares them with those seen in South Korean archeology during the same period.

The purpose of this study is to examine the research trends of social welfare in North Korea and to make suggestions for the further research. This study analyzed a total of 99 articles(from 1972 to 2009) related to social welfare in North Korea. The main findings of this study are as follows: First, the approaches of change within system are needed and this can make well-balanced perspectives. Second, the perspectives of external-totalitarian must be rejected and the immanent-critical approaches should be addressed. Third, in terms of study contents, ideological, institutional and practical studies need to be extended. Fourth, micro studies should be more developed. Fifth, in the research method, the quantitative research method, and the synthetic and comparative strategies should be more employed. Finally, use of original text should be further conducted.

The purpose of this paper is to analyze the behavior of North Korea's cyber attack against South Korea since 2009 based on major international security theories and suggest South Korea's policy option. For this purpose, this paper applied the behavioral domain and characteristics of 'cyber power' and 'coercion dynamics' model, which are attracting attention in international security studies. The types of cyber attacks from North Korea are classified into the following categories: power-based incarceration, leadership attacks and intrusions, military operations interference, and social anxiety and confusion. In terms of types and means of cyber power, North Korean GPS disturbance, the Ministry of Defense server hacking and EMP are hard power with high retaliation and threat and cyber money cashing and ransomware are analyzed by force in the act of persuasion and incentive in the point of robbing or asking for a large amount of money with software pawns. North Korea 's cyber attack has the character of escape from realistic sanctions based on the second nuclear test. It is important for South Korea to clearly recognize that the aggressive cyberpower of North Korea is changing in its methods and capabilities, and to ensure that North Korea's actions result in far greater losses than can be achieved. To do this, it is necessary to strengthen the cyber security and competence to simultaneously attack and defend through institutional supplement and new establishment such as cyber psychological warfare, EMP attack preparation, and enhancement of security expertise against hacking.

Many researches illustrated that the magnitude and frequency of hydrological event would increase in the future due to changes of hydrological cycle components according to climate change. However, few studies performed quantitative analysis and evaluation of future rainfall in North Korea, where the damage caused by extreme precipitation is expected to occur as in South Korea. Therefore, this study predicted the extreme precipitation change of North Korea in the future (2020-2060) compared to the current (1981-2017) using stationary and nonstationary frequency analysis. This study conducted nonstationary frequency analysis considering the external factors (mean precipitation of JFM (Jan.-Mar.), AMJ (Apr.-Jun.), JAS (Jul.-Sept.), OND (Oct.-Dec.)) of the HadGEM2-AO model simulated according to the Representative Concentration Pathway (RCP) climate change scenarios. In order to select external factors that have a similar tendency with extreme rainfall events in North Korea, the maximum annual rainfall data was obtained by using the ensemble empirical mode decomposition (EEMD) method. Correlation analysis was performed between the extracted residue and the external factors. Considering selected external factors, nonstationary GEV model was constructed. In RCP4.5, four of the eight stations tended to decrease in future extreme precipitation compared to the present climate while three stations increased. On the other hand, in RCP8.5, two stations decreased while five stations increased.

We are constantly hearing about the seriousness of food shortages in North Korea through various media reports. Recently, the severity of the problem has increased, and international organizations and relief organizations have become increasingly concerned. Due to the shortage of food and firewood, residents illegally cut trees in the mountains and, as a result, North Korea has become the third fastest-growing area of forest degradation in Asia. However, since North Korea cannot directly measure the extent of forest degradation, remote sensing techniques using satellite imagery have to be applied. The purpose of this study was to analyze the characteristics of forest change in North Korea, in order to understand the severity of the forest degradation problem. For this purpose, Landsat 5 TM and Landsat 8 OLI TIRS satellite images were acquired and classified. As a result, it was found that the forests have turned into wilderness in the Nampo City and Pyongyang municipalities, while the wasteland has changed into forests in the north of Yanggangdo. In addition, the total forested area of the whole region decreased by $4,166.22km^2$, the residential area decreased by $2,017.03km^2$, and the amount of agricultural land increased by $6,625.74km^2$, which is similar to the amount of forested area lost, although the difference in the overall area of the forests between 2017 and 2006 was small.
