국내 반도체 산업은 불과 20년도 안 되는 짧은 기간동안에 괄목할만한 성장을 하여 전세계 반도체 생산 규모 면에서 3위 국가로 부상하였으며, 기술 경쟁력 면에서도 한국인의 자존심을 그나마 지켜왔다. 하지만, 반도체 제조는 가장 복잡한 제조공정의 하나로 분류되며, 이러한 복잡한 시스템을 통제하기 위해서는, 다양한 시스템 조건 하에서 적절한 생산전략을 마련하는 것이 필요하다. 그러나, 반도체 제조 시스템에 대한 다양한 상황과 관련한 연구는 많지 않다. 반도체 제조공정 시스템에 대한 스케줄은 생산공정의 재진입, 공정의 높은 불확실성, 급속하게 변하는 제품과 기술과 같은 특성 때문에 반도체 제조공정 시스템에 대한 스케줄은 복잡하고 어려운 작업이며, 사이클타임의 절감 및 단위시간당 생산량의 증대와 같은 시스템 목적을 달성하기 위하여, 반도체 제조 시스템에 대한 좋은 방법을 발견하기 위한 많은 연구가 있었다. 반도체 산업의 생산 흐름은 가장 독특한 특징을 가지고 있으며 생산계획과 반도체 제조의 스케줄링과 계획을 어렵게 하고 있다. 현재 반도체 조립공정에서 수행되고 있는 일정계획은 단순 FCFS (First Come First Serve)에 의한 할당규칙에 따른다. 또한 Backlog(예비재고)를 1일 생산량을 기준으로 Buffer로 운영하고 있다. 따라서 본 연구에서는 효율적인 재고관리와 정확한 스케줄링이 생산의 경쟁력 확보 우위임을 가정하여 다양한 할당규칙(dispatching rule)을 실시간 적용하여 정확한 일정계획 수립의 효과와 결과를 시뮬레이션을 통해 검증하고자 한다. 제시된 방법론을 위하여 시뮬레이션 접근방법이 사용되었다.

하천의 수질을 나타내는 환경지표 중 국가 TMS(Tele Monitoring system)의 수질측정망을 통해 관리되고 있는 지표로는 DO, BOD, COD, SS, TN, TP 등 여러 인자들이 있다. 이러한 수질인자는 하천의 자정작용에 있어 많은 영향을 나타내고 있다. 이를 활용한 경제적이고 합리적인 수질관리를 위해 하천의 자정작용을 활용하는 것이 중요하다. 생물학적 작용을 가장 효과적으로 활용하기 위해서는 수질오염 데이터에 기초한 수질예측을 채택하여 적절한 대책이 필요하다. 이를 위해서는 수질인자의 데이터를 측정하고 축적해 수질오염을 예측하는 것이 필수적인데, 실제적으로 수질인자의 일일 측정은 비용 관점에서 쉽게 접근할 수 없다. 본 연구에서는 시계열 학습으로 알려진 RNN-LSTM(Recurrent Neural Network-Long Term Memory) 알고리즘을 활용하여 기존에 측정된 수질인자의 데이터를 통해 시간당 및 일일 수질인자를 예측하려고 했다. 연구에 앞서, 기존에 시간단위로 측정된 수질인자 데이터의 이상 유무를 확인 후, 에러값은 제거하고 12시간 이하 데이터가 누락되었을 때는 선형 보간하여 데이터를 사용하고, 1일 데이터도 10일 이하 데이터가 누락되었을 때 선형 보간하여 데이터를 활용하여 수질인자를 예측하였다. 수질인자를 예측하기 위해 구글이 개발한 딥러닝 오픈소스 라이브러리인 텐서플로우를 활용하였고, 연구지역으로는 대한민국 부산에 위치한 온천천의 유역을 선정하였다. 수질인자 데이터 수집은 부산광역시에서 운영하는 보건환경정보 공개시스템의 자료를 활용하였다. 모델의 연구를 위해 하천의 수질인자, 기상자료 데이터를 입력자료로 활용하였다. 분석에서는 입력자료와, 반복횟수, 시계열의 길이 등을 조절해 수질 요인을 예측했고, 모델의 정확도도 분석하였다.

The price of land in Jeju is reaching a new high every day and this phenomenon not only causes real difficulties for the purchase of real estate by local residents, but also results in psychological deprivation. Therefore, this study analyzes the factors causing the increase of the land price in Jeju, in order to examine the measures required to stabilize the land price which is continuously rising. As a result of this study, we developed a land price prediction model including seven variables, including the 'inflation rate', 'interest rate', and 'population'. According to the model, land prices in Jeju are expected to rise steadily, and it is predicted that in 2020 the price will increase to 170% of that in 2015 and will triple by 2025. Based on the results of this study, this study suggested policy alternatives, such as 'Establishing a tourism policy for managing the number of tourists' and 'increasing the approval standards for development activities'. The two policies proposed in this study can be implemented as a regional initiative, which may be less effective than the changes in the national system, but it is meaningful that the efforts to stabilize the land price will continue at the regional level.

역량(capacity)이란 진술된 목표를 수행할 수 있는 능력을 의미하므로, 목표란 그 목표를 성취하기 위해서 요구되는 역량의 구체적 요소, 양, 질, 그리고 역량의 소재를 결정한다. 건강증진이란 문제를 파악하고 해결하기 위한, 그리고 조직이나 사람들이 그들의 목표를 성취하기 위한 응용과학으로 발전되어 왔다. 문제를 분석하고, 문제의 원인이나 결정요인들을 파악하고, 그리고 해결책을 제시하고 이를 실행하는데 있어 효과적인 방법론이 중요하다는 점도 또한 밝혀졌다. 그러므로 효과적인 건강증진의 토대가 되는 방법론은 건강을 증진을 위한 역량으로 정의될 수 있을 것이다. 목표는 매우 중요한 역할을 한다. 평균 기대수명을 향상시키는데 요구되는 능력은 생물학적인 그리고 행동적 건강위험을 감소시키는데 필요한 능력과는 다르다. 그리고 질병의 발생을 예방하고, 또는 상해를 예방하거나 모든 사람들이 좋은 건강상태를 얻고 유지하는데 동등한 기회를 갖는 환경을 조성하는 능력도 다른 특성을 지닌다. 방콕헌장은 현 단계의 건강증진을 위하여 건강에 대한 사회적 결정요인에 대한 해결책과 더불어 건강에 도움이 되는 사회적, 경제적, 그리고 물리적 환경을 조성하여 건강형평성을 달성하고자 하는 목표를 설정하고 있다. 지난 30년간 건강증진을 위한 역량에 대하여 많은 것들을 배울 수 있었다. 이러한 역량을 기르고 확대하는 것이 미래를 위한 도전과제가 되며, 비록 우리가 성취한 것이 많지는 않을지라도, 더 많은 것들이 필요하다는 점은 명백해졌다. 우리는 좀 더 야심 찬 목적을 가져야 하며, 이러한 목적달성을 위하려 좀더 의욕적인 노력을 해야 할 것이다. 전문분야로서 건강증진은 다른 사람들에 의하여 발생된 문제에 대한 대책이나 반응에만 중점을 둔 이방인으로서의 역할을 해왔다. 그러나 우리가 도전해야 할 과제는 좀 더 새롭고, 더욱 야심 찬 활동계획을 설정하고 우리가 건강해지고 건강을 유지하는데 필요한 생활환경, 작업환경, 여가환경, 영적 환경을 모든 사람들에게 제공할 수 있는 가족, 지역사회, 그리고 국가가 있는 세계를 만드는 우리사회의 능력들을 신장하는 것이다. 방콕 헌장은 건강증진을 위한 새로운 일련의 목표들을 제시하고 있다. 이제 이러한 목표를 성취할 수 있도록 역량을 기르는 것은 우리의 책임이 되었다. 이는 원하는 활동수준을 달성하기 위한 역량을 조율하고 확장시키는 것을 의미할 것이다. 구체적으로 기존의 건강증진효과성에 관한 증거들을 좀더 큰 규모의 사업으로 확대시키는 것, 공공정책을 개발하고 건강증진 상태를 평가하는 데 다양한 지역사회의 참여를 촉진시키는 능력, 언어, 인종, 성, 종교, 장애 등과 관련된 건강형평성의 문제를 파악하고 제거하는 노력, 그리고 정책결정과 인구집단의 건강과의 관련성에 대한 증거수집, 국가와 지역차원에서 사회적 의사결정 과정에의 적극적 참여, 다른 부문과의 건강증진을 위한 협력 등이 포함된다고 볼 수 있다. 본 논문은 방콕헌장을 분석함으로써 이러한 역량이란 무엇인가에 대한 본인의 의견을 제시하였다. 이러한 아이디어는 토론과 논쟁을 위하여 제시된 것이다. 명백한 것은 건강증진을 위한 역량은 전략이나 기술적인 능력 뿐 만이 아니라 정치적 능력이나 개인적인 능력도 포함된다는 점이다. 가치와 증거들이 정책이나 권력과 함께 결합되어야하며, 정치적인 논쟁 속에서 연마되어야 한다. 우리세계의 미래는 역량에 의존하기 때문이다.

To quantitatively evaluate the influence of ground granulated blast-furnace slag (GGBS) as a supplementary cementitious material on the life-cycle environmental impact of concrete, a comprehensive database including 3395 laboratory mixes and 1263 plant mixes was analyzed. The life-cycle assesment studied for the environmental impact of concrete can be summarized as follows: 1) the system boundary considered was from cradle to pre-construction; 2) Korea life-cycle inventories were primarily used to assess the environmental loads in each phase of materials, transportation and production of concrete; and 3) the environmental loads were quantitatively converted into environmental impact indicators through categorization, characterization, normalization and weighting process. The life-cycle environmental impacts of concrete could be classified into three categories including global warming, photochemical oxidant creation and abiotic resource depletion. Furthermore, these environmental impacts of concrete was significantly governed by the unit content of ordinary portland cement (OPC) and decreased with the increase of the replacement level of GGBS. As a result, simple equations to assess the environmental impact indicators could be formulated as a function of the unit content of binder and replacement level of GGBS.

We increasingly see the importance of employees acquiring enough expert capability or innovation capability to prepare for ever growing uncertainties in their operation domains. However, despite the above circumstances, there have not been an enough number of researches on how operational input components for employees' innovation outcome, innovation activities such as acquisition, exercise and promotion effort of employee's innovation capability, and their resulting innovation outcome interact with each other. This trend is believed to have been resulted because most of the current researches on innovation focus on the units of country, industry and corporate entity levels but not on an individual corporation's innovation input components, innovation outcome and innovation activities themselves. Therefore, this study intends to avoid the currently prevalent study frames and views on innovation and focus more on the strategic policies required for the enhancement of an organization's innovation capabilities by quantitatively analyzing employees' innovation outcomes and their most suggested relevant innovation activities. The research model that this study deploys offers both linear and structural model on the trio of learning, innovation capability and innovation outcome, and then suggests the 4 relevant hypotheses which are quantitatively tested and analyzed as follows: Hypothesis 1] The different levels of innovation capability produce different innovation outcomes (accepted, p-value = 0.000<0.05). Hypothesis 2] The different amounts of learning time produce different innovation capabilities (rejected, p-value = 0.199, 0.220>0.05). Hypothesis 3] The different amounts of learning time produce different innovation outcomes. (accepted, p-value = 0.000<0.05). Hypothesis 4] the innovation capability acts as a significant parameter in the relationship of the amount of learning time and innovation outcome (structural modeling test). This structural model after the t-tests on Hypotheses 1 through 4 proves that irregular on-the-job training and e-learning directly affects the learning time factor while job experience level, employment period and capability level measurement also directly impacts on the innovation capability factor. Also this hypothesis gets further supported by the fact that the patent time absolutely and directly affects the innovation capability factor rather than the learning time factor. Through the 4 hypotheses, this study proposes as measures to maximize an organization's innovation outcome. firstly, frequent irregular on-the-job training that is based on an e-learning system, secondly, efficient innovation management of employment period, job skill levels, etc through active sponsorship and energization community of practice (CoP) as a form of irregular learning, and thirdly a model of Yί=f(e, i, s, t, w)+${\varepsilon}$ as an innovation outcome function that is soundly based on a smart system of capability level measurement. The innovation outcome function is what this study considers the most appropriate and important reference model.

Due to the lack of national consensus on the importance and value of the character industry and the lack of recognition of value as a national strategic industry, the development of the character industry is experiencing great difficulties. The purpose of this study is to analyze the economic effects of character industry in China to help establish policies and strategies for the character industry in the future. To this end, this study utilized the China 2017 Industrial Association Table. The analysis results are as follows. China's character industry has a lower production inducement effect than other industries with a column total of 3.45514, and a row total of 1.30015. This shows that China's character industry is still being produced by small and medium-sized companies with a low equity ratio. Second, in the character industry, the index of the sensitivity of dispersion representing the forward linkage effect is 0.01426 and the impact factor is 0.03790, which are all less than 1. Therefore, it can be said to be the final demand manufacturing type.Third, in China character industry's income induction is 0.47690 and the production tax induction effect is -0.04912. It can be seen that the character industry has less income induction and tax burden generated every time the final demand increases by one unit in the entire industry than in other industries.Despite the quantitative growth of the character industry in China, the impact on other industries is low and it is not playing a role as an income-generating industry. Structural improvement is needed for the qualitative development of China's character industry.

This study fundamentally is to develop standards and foundations for the establishment of traditional Korean gardens and aims to identify the mechanism and subsequent effect of fair gardens in American and Europe on the propagation and diffusion of the traditional Japanese garden. Fair gardens which were constructed between 1867 and 1939 were investigated to understand them and the ripple effect that they had on cultural dissemination. The results were as follows: Culturally, the Meiji government adopted Wagener's advice on the theme of display- including culture and handicraft-and the gardens with traditional buildings were perceived as one unit and then used as promotional tools as part of a national strategy. As a result, the stroll style garden in the Edo period and tea garden were recognized as the representative Japanese garden in America and Europe. Politically, the Japanese garden in the American context was adopted as examples of 'exotic beauty' and 'cultural heritage' which therefore allowed the Japanese government to achieve it's goal of encouraging friendly relations and the lessening of hostility towards them. Throughout the traditional Japanese garden, Japan with it's rich history presented an ideal - uniquely distinctive from the West. Using 'tradition' and 'nature' as keywords, the Japanese government set it's global image as 'perpetual tranquility'. Socioeconomically, the Japanese garden which was maintained after the fair, played a consistent role as a model of the Japanese culture. Many professionals from Japan who prepared the Japanese villages and gardens for the world fairs in America and Europe, remained in these countries following construction and it were these opportunities that allowed the Japanese garden to be integrated into local Western society.
