Reddish superficial materials in southern area of Korean Peninsula have been defined as lateritic red soil in Korea. In A-CN-K ternary plots, CaO and $Na_2O$ show similar linear distribution along a A-K line to kaolinite profile and laterite in southern Spain and Cameroon, respectively, and it means strong alteration. But $K_2O$ is weak alteration, plotting between muscovite and illite zone. Granitic reddish weathering mantles in study area show bulk distribution in center when plotted in A-CNK-Fm space, in contrast to laterite in Cameroon, plotting linearly in the middle along a A-FM line. Therefore, alteration of reddish saprolites in Southern Korea have not progressed as much as laterite. To define Reddish saprolite in southern Korean Peninsula as a lateritic red soil, more many studies are necessary.

This research dwells on categorization and industrialization of cultural heritage resources using marketing. Since many organization would not grab the chance of business while doing marketing using cultural heritage, the paper intend to suggest proper way to develop strategy. For that purpose, this research analyzed some advanced cases of corporate like Google and other national endeavors. This paper founded out 4 models of marketing using cultural heritage resources. These are re-creation, patron, capitalization and media. Also we got practical implications of the case analysis and modeling which are collaboration partnership scheme between marketers and filed expert group. Marketers better find fitful information and right person utilizing more reliable sources such as national archives, and academic achievements. If the marketers implement such strategic program, really abundant types of cultural heritage resources using marketing could bring more favorable profit which means business chance and new horizon for global culture industry.

부유사 수리실험에서 부유사의 농도를 측정하는 것은 불확실성이 매우 크다. Einstein(1950)은 유사의 pickup function 결정에서 이러한 불확실성 때문에 유사입자의 거동을 발생시키는 양력의 확률을 적용하기도 하였다. 일반적으로 부유사의 측정은 부유사 채집기를 통해 수행하지만, 시간적으로 비효율 적이며, 채집 시 채집기의 부피로 인한 난류 발생으로 채집 후 흐름 변화가 발생할 수 있다. 수리실험의 규모라면 이 문제는 더욱 부각될 수 있다. 연속적인 부유사의 농도 측정을 위해 이러한 점은 개선되어야 하는 문제이다. 본 연구에서는 유사 실험의 이러한 단점을 극복하고자 image processing 기법을 적용하였다. Image processing은 부유사의 농도가 증가할수록 탁도가 증가하는 특성을 이용하여, 부유사 농도를 추정하는 방법이다. 이 과정에서 RGB(Red-Green-Blue)로 색을 표시하는 방식에서 image를 변환하여 gray scale로 전환해야 하며, 파(wave)의 전파에 의한 image 결과의 변형은 없다고 가정하였다. Gray scale과 탁도와의 관계를 도출하기 위해 하상에 유사를 포설하고, 단파(surge)를 발생 시켰다. 실험은 길이 12.0m, 폭 0.8m, 높이 0.75m의 개수로에서 수행하였으며, 수로 상류에 sluice형 gate를 급격하게 개방하는 것으로 단파를 재현하였다. 탁도 측정을 위해 유사 채집기를 이용하였으며, 상기에서 제시한 흐름 교란문제로, 1지점에서 1개의 시간동안만 채집을 수행하였으며, image의 촬영을 병행하였다. 또한 data의 정확도를 높이기 위해 3번의 반복실험을 수행하였다. 실험결과 gray scale과 탁도와는 일정한 관계가 나타났으며, 이를 토대로 gray scale-SSC(suspended sediment concentration)와의 관계를 도출하였다. Bayesian 분석을 이용하여 image processing의 보정(확률적 보정)을 추가적으로 수행하였다. 최종적으로 실측한 값과 image processing을 통한 값을 1:1 curve를 통해 비교하였으며, 약 9%의 평균 오차가 발생하여, image processing과 bayesian 적용을 통한 부유사 농도 측정은 신뢰할 만한 결과를 도출하는 것으로 판단된다.

In the latest trend of machine translation research, the model is pretrained through a large mono lingual corpus and then finetuned with a parallel corpus. Although many studies tend to increase the amount of data used in the pretraining stage, it is hard to say that the amount of data must be increased to improve machine translation performance. In this study, through an experiment based on the mBART model using parallel corpus filtering, we propose that high quality data can yield better machine translation performance, even utilizing smaller amount of data. We propose that it is important to consider the quality of data rather than the amount of data, and it can be used as a guideline for building a training corpus.

The concept of 'utopia' in Korea was formed in the early 20th century. 'There isn't in this world but good world' could be found using science and it was an ideal place for science to realize in the 1900s of Korea. Utopia was emphasized as an ideal world of fantasy in the 1920s. It was an ideological world wherein socialism was realized by a purposeful science. Utopia, conversely, was the history of scientific socialism defined as past example of communism that could not be implemented but was fancied. There were works suggesting that it was a dark dystopia such as Society after 800,000 years written by H.G. Wells or Artificial Worker by Young-hee Pak, but there were implied at the will of utopia.

V.V. Rozanov, a well-known writer and thinker, has wrote many critical essays about Russian literature and writers. The most famous literary criticism written by him is an essay about F. Dostoevsky - Legend of the Grand Inquisitor (1894), which has been highly appraised by N. Berdyaev. If Dostoevsky was the best and the most admirable writer by Rozanov, Gogol was one of the most condemned one by him. This paper, first of all, aims to analyze Rozanov's literary essays about Gogol. At this time, our subjects of analysis included writer's critical essays about Pushkin and Dostoevsky because Rozanov tried to investigate the nature of a creation of Gogol through comparative studies. Based on these analyses, we attempted to deduce an overall view of Rozanov about Russian literature. We also examined the influence of Rozanov on the later criticism.

The core of the block chain technology is solving the problem of agreement on double payment, and the PoW, PoS and DPoS algorithms used for this have been studied. PoW in-process proofs are consensus systems that require feasible efforts to prevent minor or malicious use of computing capabilities, such as sending spam e-mail or initiating denial of service (DoS) attacks. The proof of the PoS is made to solve the Nothing at stake problem as well as the energy waste of the proof of work (PoW) algorithm, and the decision of the sum of each node is decided according to the amount of money, not the calculation ability. DPoS is that a small number of authorized users maintain a trade consensus through a distributed network, whereas DPS provides consent authority to a small number of representatives, whereas PoS has consent authority to all users. If PoS is direct democracy, DPoS is indirect democracy. This study aims to contribute to the continuous development of the related field through the study of the algorithm of the block chain agreement.

"사실 국가건축정책위원장 책임을 떠안는 것에 고민을 많이 했습니다. 작금 건축의 본질에 관해 꽤 진지하게 논하는 결정권자들이 많아진 상황에서 직을 맡은 이상 그냥 시간만 보내진 않을 겁니다. 평소 생각한 건축계의 부족한, 불합리한, 불비한 부분을 임기 중 완전히 고치진 못한다 하더라도 시작은 해놓고 끝내려 합니다." 작년 4월 취임한 승효상 대통령소속 국가건축정책위원장이 국내 건축계 현안에 대한 생각과 앞으로의 계획을 설명했다. 그가 걸어온 삶의 궤적에는 건축의 공공성 문화적 가치라는 단어들이 새겨져 있으며, 이는 그가 활동해 온 건축계 여러 운동 모임에서도 살펴볼 수 있다. 지식인으로서 마땅히 지녀야 할 건축사(Architect)의 책무에 관해서는 쓴소리도 서슴지 않았던 그다. 2014년 서울시 '초대 총괄건축가'로 선임돼 서울시의 도시정책과 건축문화, 공공 공간조성 등 도시계획 전반에 대해 역할을 했다면, 이젠 국가 건축정책의 목표와 관계 부처간 건축정책의 심의.조정까지 그 역할범위가 커졌다. 필드의 건축사라면 승효상 국가건축정책위원장에게 기대하는 바가 큰 게 사실이다. 실제 그의 취임 후 정부 내 국건위의 위상은 과거와 달라졌으며, 작년 9월 4일에는 문재인 대통령이 서울 은평구 구산동 도서관마을에서 열린 '대한민국 국민생활 SOC현장 방문, 동네 건축현장을 가다' 행사에 참석해 도서관, 체육관, 경로당 등 '생활 SOC 혁신의지'를 강조해 눈길을 끌었다. 최근 정부세종신청사 설계공모 관련 논란에는 "국토부에 소관 설계공모 규정을 고쳐야 함을 권고했다. 고칠 거다! 안 고치면 안 되게 돼 있다!"며 목소리에 힘을 주어 재차 강조했다. 제5기 대통령소속 국가건축정책위원장으로 선임돼 지난해 4월부터 역할을 해온 승효상 건축사를 종로구 동숭동 (주)종합건축사사무소 이로재(履露齋)에서 만났다.

The purpose of this study was to develop a technology commercialization strategy by analyzing the consumer preference for low-sodium instant noodle ramen, which has a sodium content of 1,730 mg or less. For the commercialization of such low-sodium ramen, this study examined how much consumers would pay through an analysis of consumer preference by conjoint analysis. This study surveyed 1,004 men and women in their 20 s and 50 s between the ages of 20 and 50 years in Korea using an online survey. If the price of conventional instant noodle ramen is KRW 4,000 (approximately USD 3.57) per 5 packs for one pack of 5 servings in a supermarket, this study surveyed how much more they respondents would pay if the sodium was reduced by 10.0, 20.0, and 30.0%. The study found that if sodium was reduced by 10.0, 20.0, and 30.0%, the respondents would pay as much as KRW 4,180, KRW 4,307, and KRW 4,515, respectively. The attributes of low-sodium instant noodle ramen were examined according to the degree of sodium reduction, vegetable protein ingredients, brand, where to buy and price with each level. The Marginal Willingness To Pay (MWTP) was analyzed as follows. If the sodium content of ramen soup is reduced by 1.0%, the amount that can be paid would be KRW 105.78. Respondents could pay KRW 1,673 more for famous brand ramen than an unknown brand ramen. The study results indicated that when a new product is developed and released, it can be expected to increase sales of the new product by understanding the foreseeable value that consumers could pay for and realize the technological commercialization of the technology.

The purpose of this study is to explore whether entering the overseas market can be an opportunity in overcoming the limitations of the single profit structure in which the traditional performing arts industry relies on public support. To this end, we applied the concept of industrial value-chain and business model and divided the overseas market entry process into four stages-preparation, promotion, harvest, and follow-up. Based on three case-studies that actively pursued overseas market development with market-oriented thinking in the field of traditional music, the relevant entry model of overseas market for the Korean traditional performing arts industry was suggested. Although the overseas market is not yet a major source of revenue, the traditional performing arts teams searching for profit diversification can consider the overseas entry model derived from this study. Also as found in case studies, the Korean government should establish an institutional system to foster planning and distribution experts in charge of overseas markets for the traditional performing arts, and develop a long-term information provision program away from the one-time expense support.
