The PoN (Proof of Nonce) distributed consensus algorithm basically uses a non-competitive consensus method that can guarantee an equal opportunity for all nodes to participate in the block generation process, and this method was expected to resolve the first trilemma of the blockchain, called the decentralization problem. However, the decentralization performance of the PoN distributed consensus algorithm can be greatly affected by the network transaction transmission delay characteristics of the nodes composing the block chain system. In particular, in the consensus process, differences in network node performance may significantly affect the composition of the congress and committee on a first-come, first-served basis. Therefore, in this paper, we presented a problem by analyzing the decentralization performance of the PoN distributed consensus algorithm, and suggested a fairness control algorithm using a learning-based probabilistic acceptance rule to improve it. In addition, we verified the superiority of the proposed algorithm by conducting a numerical experiment, while considering the block chain systems composed of various heterogeneous characteristic systems with different network transmission delay.

WAIS in South Korea and WEU Inc. in Philadelphia hosting the 22nd World Peace Island Forum: Remembering Jeju King Cherry Trees Bio-diplomacy (1943) in Washington D.C. and the first Korean Congress Democracy (1919) in Philadelphia which organized by the Korean Provisional Government from March 22 to 24, 2022. We want to propose cultural historic events which connect American and Korean society, such as the Trip to Faith and Liberty Hall that relate to the integration processes of Korean and American Democracy. Dean Max Friedman of American University calls the Jeju King cherry trees cultural event bio-diplomacy among world citizens. In addition, the Korean embassy evaluated the cherry tree event as a new kind of bio-diplomacy approach which paves the way for understanding different cultures in different countries. The aim of this paper is to share present contexts and meanings about both the first Korean Congress Democracy (1919) and Bio-diplomacy (1943). We had also the 2022 GAN Korea Jeju to Philadelphia Webinar Conference: Diversity as a New Diversity for Global Ageing Network in New Normal: Jeju Village Healing, PASSi Asian Culture, Japanese Indigenous Peace Culture, and Busan Smart Health Care approach.

In this article, firstly, we talk about why we respond to “climate change impacts in nature and society” educationally. Secondly, we try to find ways that Jeju also has the ability to halt biodiversity loss and apply nature-based solutions to conserve biodiversity, enhance resilience, and so improve the well-being of the people on the island and in turn to improve the well-being of the people on the planet at the grass roots level of UNESCO internationally protected areas. Thirdly, we try to develop World Environment University Online School Leads Establishment of World Environment University so called “Lead WEU.” We will announce “World Environment University Online School Leads Establishment of World Environment University” at Private Meeting of the 2020 World Conservation Congress on September 9, 2021 in Marseille of France. We propose ”Jeju Global Governance of World Heritage; Climate Change Impacts and Integrated Management of UNESCO internationally Protected Area, at the graduate class of Jeju National University from September 2 to December 9, 2021. The core program centered at the University itself would be developed initially on the basis of the comparative advantage offered by its location in Jeju and the quality of faculty, full and part time, that could be recruited to the University.

The University will contribute, through its high quality of education, training and research, to the containment, reduction and management of the problems confronting humanity in the transition to sustainable way of life utilizing the latest technologies of distance learning. Through international collaboration and leadership, it will generate, mobilize and share knowledge, experience and skills throughout the world so as to promote equitable and sustainable progress and to preserve and enhance the natural world on which humanity depends. As merit of the location of center in Northeastern Asia and North and South countries, Jeju Island has a remarkable natural beauty matching with unique environmental culture tradition, and a wide range of expertise, connections and capabilities in regard to global commerce, finance and transportation, and to the management of watersheds and biodiversity as a newly established international free city, all of which are relevant to world environment of sustainable development.

The name of the University. While there is a close relationship between the environment and peace, this should be reflected in the establishment of an institute or program rather that in the name of the University which should be, as originally conceived, the World Environment University. The credibility of the University will depend on the involvement in it from the beginning of highly influential leaders of the world environment movement. There is no better way of ensuring this than to obtain the formal involvement of IUCN which has in its membership most of the leading nongovernmental and governmental organizations of the environment and conservation movement

We want to have an opportunity to learn in a global context why GAN is so important to Jeju as Korea's largest Island in a multi-cultural society. Politically, Jeju Island succeeds have to survive ordeal from Jeju 4.3 Grand Tragedy. Geologically, as Jeju Island is located at center of East Asia, it has benefits from easy access to main cities to the island such as Beijing, Shanghai, Tokyo, Osaka, Seoul, Busan, Hong Kong, Taipei and so on. Environmentally, as Jeju was designated UNESCO Biosphere, World Natural Heritage and Geo parks, we want to keep it as a longevity island. Culturally, as we recognize it as a specialized in Western countries by human peace, Jeju as a World Peace Island tries to integrate aging human life agenda into part of a human life one. As the result, we suggest “Korea Care into Global Humanity in the Asia Pacific Context” as integrated policy agenda of both Korea and Peace Island villages for the 2021 GAN Biennial Conference from September 26 to 30, 2021 in Jeju Island Korea. As it based on village healing by villagers, Jeju island is small, as there is slrong soldarity between, we believe it can revive Korea communities.

This study is investigated the growth characteristics(number of available stipe, pileus diameter, pileus thickness, stipe length, stipe thickness, object weight, comparison yield ability of 1 cycle) and storage characteristics of ‘Sanjo 701’ (S7) cultivars according to relative humidity. The S7 growth characteristics were investigated by quantifying the growth and the characteristics according to the relative humidity, The storage stability was investigated every 5 days and freshness was measured by ‘Minamide Method’. S7 pileus diameter is The higher the relative humidity was confirmed becomes larger and the more increased relative humidity also increase the comparison yield ability of 1 cycle. However, pileus diameter or stipe length This could not see the big difference in the three treatment groups, the plieus thickness was no significant difference in the treatment of 80% and 95%. The fresh weight of S7 decreased significantly at 80% and 95% relative humidity after 10 days of storage, but decreased continuity in 65% humiditiry. The elongation percentage of S7 pileus was observe in 95% relative humidity, values of L, a and b (SCI), showed the highest L value in 65% and the a value in 95%. b values were similar in 65%, 80% and 95% treatments. On the ‘Minamide Method’ measure freshness was changed from the 10th day of storage at relative humidity of 95%, but humidity of 65% and 80% treatments, it changed after 15 days of storage. In this study growth characteristics and yield were increased at higher relative humidity, but storage stability was decreased. Therefore, it is deemed necessary to change the relative humidity to produce high quality mushrooms.

ABSTRACT The growth of the social platform has led to a rapid increase in sustainable value cocreation activities with customers in order to know what a customer wants. In this study, we have studied about co-creation experience in social platform service. Previous prior studies have systematically classify co-creation between customer and enterprise as co-product and value-in-use, Conceptual factors. The co-creation and value-in-use factors theoretically derived from previous researches attempt to investigate the relationship between value co-creation experience and online service quality. We also tried to investigate the relationship between value co-creation experience and online service quality, customer equity, and online word of mouth. To do this, social platform services are divided into open sns and closed sns. Open SNS was targeted to Facebook, Twitter, and Pintrest users. Closed sns were targeted to Instagram, Cyworld, Band, and KakaoTalk users. In this study, it was confirmed that the relationship between online service quality, customer equity, and online word of mouth is significant through value co - creation experience. In the future, companies that design social platforms will be asked to do what they should do to co-create with customers, and provide suggestions for how to operate the platform in order to continuously activate value co-creative experiences.

Metformin (1,1-dimethylbiguanide hydrochloride), derived from French lilac (Galega officinalis), is a first-line anti-diabetic drug prescribed for patients with type 2 diabetes. However, the role of metformin in odontoblastic cell differentiation is still unclear. This study therefore undertook to examine the effect of metformin on regulating odontoblast differentiation in MDPC-23 mouse odontoblastic cells derived from mouse dental papilla cells. As compared to controls, metformin significantly accelerated the mineralization, significantly increased and accelerated the expressions of ALP and Col I mRNAs, and significantly increased the accelerated expressions of DSPP and DMP-1 mRNAs, during differentiation of MDPC-23 cells. There was no alteration in cell proliferation of MDPC-23 cells, on exposure to metformin. These results suggest that the effect of metformin on MDPC-23 mouse odontoblastic cells derived from mouse dental papilla cells, facilitates the odontoblast differentiation and mineralization, without altering the cell proliferation.

This research was relative humidity (65, 75, 85 and 95%) growth characteristics of the oak mushroom (Lentinula edodes) 'Nongjingo’. At the relative humidity was 65% in growth chamber. On this condition the moisture content of medium surface was 60.5%. That was lower than other treatments. That condition makes Pileus was 77.1% and stipe was 65%. Among the growth characteristics according to the relative humidity, the pileus diameter at 75% relative humidity were 45.5mm that largest than other treatment and pileus thickness at 75% relative humidity were largest than other treatment. The stipe thickness at 65% relative humidity were 14.8mm that lagest than other treatment. The number of available stipes at 95% relative humidity were 13.3peace/2kg that largest than other treatment. The comparison yield ability of 1 cycle was 104.2g that result in largest than other treatment at 95% relative humidity. This result was associated to the relative humidity of fruiting bodies, the lower relative humidity result in the lower of yield. However, the lower relative humidity result in the higher number of whago, Especially, at the treatment of 65% relative humidity, all the fruit bodies were produced as Whago (dry). Therefore, the higher relative humidity influenced in the higher yield but produced water mushroom. That result was thought that ‘Nongjingo’ would be possible to produce high quality mushroom by adjusting the relative humidity appropriately.

A black nickel oxide powder, one of the commercial nickel oxide ores, was reduced by hydrogen gas in a batchtype fluidized-bed reactor in a temperature range of 350 to 500 oC and in a residence time range of 5 to 120 min. The hydrogen reduction behavior of the black nickel oxide was found to be somewhat different from that of green nickel oxide ore. For the black nickel oxide, the maximum temperature (below which nickel oxide particles can be reduced without any agglomeration) was significantly lower than that observed for the green nickel oxide. In addition, the best curve fittings of the Avrami model were obtained at higher values of the overall rate constant “k” and at lower values of the exponent “m”, compared to those values for the green nickel oxide. It may be inferred from these results that the hydrogen reduction rate of the black nickel oxide is faster than that of the green nickel oxide in the early stages, but the situation reverses in the later stages. For the black nickel oxide ore, in spite of the low temperature sintering, it was possible to achieve a high degree fluidized-bed reduction at lower temperatures and at lower gas consumption rates than was possible for the green nickel oxide. In this regard, the use of black nickel oxide is expected to yield a benefit if its ore price is sufficiently lower than that of the green nickel oxide.

Even though we had a lot of obstacles to solve these issues, Jeju National University , Hokkaido University, Hawaii University, American Graduate School of the Paris, and University of Sydney have raised reparation topics through the Peace Island Forum, Peace Island Leadership School and Global Peace Bultuk Assemblies (Bultuk being a meeting place of Jeju woman divers surrounding stones at the sea side) since July of 2010. It was a cornerstone achievement that we presided over at "SOCIAL HEALING THROUGH JUSTICE: THE MASS KILLING OF KOREA JEJU ISLANDERS DURING U.S. PEACETIME OCCUPATION" with the University of Hawaii Law School and Hokkaido University together. Based on these gatherings we can start the Petition by Jeju people on Jeju Island Korea, which is calling for A JOINT SOUTH KOREA AND UNITED STATES JEJU 4.3 INCIDENT TASK FORCE TO FURTHER IMPLEMENT RECOMMENDATIONS AND FOSTER COMPREHENSIVE AND ENDURING SOCIAL HEALING THROUGH JUSTICE to advance the mutual interests of Jeju residents and the governments and people of South Korea and the United States ( March 27, 2014).

외상으로 인한 혈액담즙증은 드물지 않게 보고되고 있고 경피경간 경로를 이용한 담도내시경이나 배액술 등에 의한 의인성 손상이 증가하고 있다. 그러나 담도스텐트 제거에 따 른 대량의 혈액담즙증의 보고는 매우 드물다. 본 증례는 복부 외상으로 간엽절제술을 받은 환자에서 발생한 담즙 누출을 치료하기 위해 삽입한 담도 스텐트를 제거하면서 혈액담 즙증이 대량 출혈로 악화된 사례이다. 간외상 수술 후 담즙 누출로 플라스틱 담도 스텐트 삽입 후 호전 중에 혈액담즙증 및 담도염 발생으로 스텐트 교체 목적으로 제거하였으나 제 거하자마자 대량의 활동성 혈액담즙증으로 악화되었다. 수술 후의 담즙 누출로 인한 주변조직 손상 및 삽입된 담도 스 텐트로 인한 자극과 제거시의 손상이 원인이 될 수 있을 것 으로 생각된다. 치료는 대량 출혈로 내시경 시야가 확보되지 않아 응급 혈관조영술로 지혈술을 시행하였다. 따라서 복부 외상 환자나 수술 환자에서 담즙 누출 후 담도 배액 스텐트 는 일반적으로 시행되는 효과적인 치료 방법이나 혈액담즙 증 및 합병증으로 담도 스텐트를 교체할 때 주변 담도나 혈 관계의 합병증 유무에 대한 사전 검사를 시행하고 스텐트 제거시에도 주의를 요한다.

Introduction Why should we study marketing management processes in social network platforms? Today’s rapidly growing creative companies must adopt social network platforms. Indeed, the “twenty-first century’s wealth comes from platforms” Thus “those who possess platforms dominate the wealth of the future” (Hirano & Hagiu, 2010). After the Lehman Brothers-initiated financial crisis, companies began developing platform strategies as a cutting-edge management method for assuring consistent and stable growth. Platform strategies call for gathering relevant groups of people together in a network that then creates new business. (Hirano & Hagiu, 2010) In this study, we study a social network platform to show how marketing management processes can be applied to social network platforms. Literature Review Social Network Platforms In recent years, social network platform sites such as Facebook, Twitter, and KakaoTalk have evolved to bring people together online. Social network services (SNS) are rapidly infiltrating daily lives and facilitating communications among people by means of computers (Correa et al., 2010; Powell, 2009). Users reside at the center of social platforms where they can socialize and express a wide range of behaviors. As a force for change, social platforms are influencing marketing strategies as well. Advertising has been traditionally one-way communication from company to customers through public media and portal sites. Recently, the paradigm has changed (Yeo, 2014): companies establish relationship with customers through social platforms that allow them to talk with customers directly, exchange opinions, and share ideas. As a result, large-scale corporations, mid-sized/small companies, and one-owner companies have turned their attention to social platforms (Jhun, 2013). Moreover, the revolutionary wave has affected such diverse areas as politics, economics, society, culture, and environmental causes. Researchers have responded to social platform developments with studies that deal with concept, construction, policy, development, spatial information, social platforms, and governmental roles (Choi et al., 2012), and that deal with social platform’s social influences and future directions (Lee & Jung, 2011). Researchers have studied functions and utilization of social platform using web services and policies to support collaborative research (Pignotti & Edwards, 2012), sharing shopping information (Der Ho et al., 2010), customer engagement (Cheung, Lee, & Jin, 2011), and senior social platforms (Farkas, 2010). Social platforms emerged so recently that academic studies have failed to keep up with the urgent need to study the phenomena realistically (Yeo, 2013). Method In this study, we analyze phase 1 secretary platform by Cybermoon Co., Ltd., which has four main functions: Product name: On-Secretary PlatformCore Services ● Phase 1. Assistant Service ● Phase 2. Vision Maker Service ● Phase 3. Collaboration and Sharing Service ● Phase 4.
