국내에서 천연 제올라이트는 부존자원으로서의 높은 잠재성에도 불구하고, 용도개발에 대한 연구개발이 부진하여 관련산업이 활성화되지 못하고 있는 실정이다. 환경개선용 기능성 소재로서의 천연 제올라이트의 응용이 앞으로 국내에서 천연 제올라이트의 부가가치 향상을 도모할 수 있는 효과적인 방안이 될 것으로 생각된다. 환경산업 분야에서는 천연 제올라이트가 합성 제올라이트와의 경쟁관계에서 유리한 위치를 점유할 수 있을 것으로 판단된다. 환경산업에서 천연 제올라이트의 새로운 수요처가 형성되면 기존의 저급한 용도보다 한 단계 향상된 부가가치의 창출이 가능할 것으로 여겨진다. 국내산 천연 제올라이트의 자원잠재성과 부가가치를 제고시키기 위해서 앞으로는 관련산업이 응용광물학적 지식기반 산업으로 전환되어야 한다. 또한 지금까지 국내에서 천연 제올라이트에 관례적으로 적용되어 왔던 화학조성 및 CEC 분석자료에 의거한 제올라이트의 품위 및 품질 평가 방식에서도 개선과 보완이 요구된다. 특히 X-선회절 정량분석, 전자현미경관찰, 선택적 이온교환 및 흡착특성과 관련된 실험 등을 통해서 천연 제올라이트의 품위와 품질이 보다 정밀하게 감정되고 평가되어야 할 것으로 여겨진다. 따라서 앞으로는 천연제올라이트의 부가가치 향상을 위한 연구개발과 산업응용은 반드시 제올라이트의 세공구조, 광물상, 광물 조성 및 특성에 대한 이해와 지식에 기반하여 이루어져야 할 것이다.

본 논문은 국가학술연구인력 데이터베이스의 구축 방안에 대해 기술했다. 학술연구자 정보는 국가적 연구지원 관련 업무의 가장 기본이 되고, 사회 각 분야에 있어서의 연구활동에 참여할 최적의 연구자를 찾거나 연구계획서를 심사할 최적의 심사자를 찾는데 필수적이다. 그러나 학술연구자 관련 정보들이 중복 구축되어 여러 낭비요소들이 많고 정보의 일관성이 유지되지 않아 정보로서의 질적 가치 저하로 오히려 혼란만 가중되고 있으며, 표준화 미비로 상호 정보 교환이 어려운 실정이다. 따라서 국가적 차원에서 표준 형식의 국가학술연구인력 데이터베이스를 구축하여 모든 관련 기관이나 연구자들이 공유함으로써 중복 구축에 따른 비용을 절감하고, 일관성을 유지하여 정확한 정보를 제공할 수 있는 구축방안을 제시하고자 한다.

In this paper, I am going to analyze a commercial film narrative focused on a temporal order through the theory of narrative discourse by Gerard Genette. Advertisements has a special quality or feature to be convertible into mythological hyper reality to advertise an product effectively. In this process, narrative in a commercial film has visual variations using a temporal order to show an glamorously advertisements in television. The reason that narrative in a commercial film is subject to variation with a temporal order, duration, frequency is to get some aesthetic effect for making sure people see them. Under the influence of postmodernism, image making like a pop-art became the first consideration in a commercial film with the consequence that representation as a signifier came to be more important than object as a signified. As a commercial film have more sensational image as a result of visual variation, images in a commercial film became vague so that it does not explain or express an advertising concept dearly. However, those aspects have assets that it gives the TV audience a room for interpretation in advertisements by themselves.

Advancement of mobile technology opened new business field in existing marketing area and in spirit of depression of advertisement market due to worldwide shrunken business, investment mobile advertisement market only jas a tendency to increase. In this paper I tried to know some factors to influence on the acceptance of customer to receive the referring advertisement continually through the study of 'KaKaotalk Plus Friends', a kind of marketing platform of KaKaotalk, the model killer application of Smart Phone. For this purpose I developed the research model based on Customer Value Theory and Social Exchange Theory etc. Futhermore based on these theories I studied the facts to influence on the acceptance of customer using KaKaotalk Plus Friends Service.

Rice, which occupies about 60% of the farmland in Korea, is a staple crop in Asia. It not only absorbs $CO_2$ from the atmosphere, but also emits carbon in a form of CH$_4$. It has a potential role in the global budget of greenhouse gases because of its relative contributions of carbon absorption and emission associated with changing hydrologic cycle. To better understand its current and future role, seasonal variations of energy and $CO_2$ exchange in this critical ecosystem need to be quantified. The purpose of this study was to measure, document and understand the exchange of energy and $CO_2$ in a typical rice paddy in Korea throughout the whole growing season. Since late April of 2002, we have conducted measurements of energy and $CO_2$ exchange in a rural rice paddy at Hari site, one of the Korea regional network of tower flux measurement (KoFlux). After the quality control and gap-filling, the observed fluxes were analyzed in the context of micrometeorology and biophysics. $CO_2$ and energy exchanges varied significantly with land cover changes (e.g., plant growth stages), in addition to changes in weather and climate conditions. This study, reporting first direct measurement of energy and $CO_2$ exchange over a rice paddy in Korea, would serve as a useful database as one of the reference sites in AsiaFlux and FLUXNET.

(Estimating Compensation for Personal Information Infringement) As the value of personal information increases, personal information infringements is more likely to happen. The compensation for personal information infringements needs to be calculated in the process of infringement remedy. However, as personal information is regarded as non-market goods with no exchange price and calculating the remedy for mental sufferings from infringements has no guideline, it is not easy to determine the compensation amount. In this study, we adopt Contingent Valuation Methods (CVM) to analyze Willingness to Accept (WTA) of each type of personal information. Also, this study attempts to examine a standard model for calculating compensation by applying JNSA JO Model of Japan, which is not prepared in Korea. This study does not simply present a plan of estimating compensation. By measuring the value of personal information, it could awaken companies and organizations to the importance of personal information security.

Any money model should address the most important phenomenon of a monetary economy, which is the phenomenon of the rate of return dominance. Even if the holding returns on financial or nonfinancial assets are higher than the rate of return on fiat money holding, which is typically zero, people still hold and use money. In a period of accelerating inflation, number of dominating assets increases continuously, yet people continue to hold and use money. Wallace's (1980) overlapping generations model cannot address the rate of return dominance phenomenon. His model does not capture the mediun of exchange role of fiat money. In this paper, an overlapping types model of fiat money is constructed, in which different types of consumers have different preferences on different types of goods, are endowed with different types of goods, are located at seperated regions, and live for only two periods. In this model, people hold and use money despite the dominating assets, even if inflation accelates. Money in this case serves as a pure medium of exchange, whereas in Wallace's model, money serves as a pure store of value, and money disappears if a dominating asset exists. An interesting feature of the overlapping types model presented in this paper is that money does not provide a cheap approximation to an idealized and efficient real allocation. A monetary economy is always superior to a nonmonetary economy, because money helps overcome the incompleteness of the overlapping types friction. In a monetary economy, however, a pareto optimal allocation cannot always be achieved, because money cannot always overcome the overlapping types friction itself. Therefore, with the criterion of optimality of real allocations, the monetary economy is more optimal than a nonmonetary economy but less optimal than a complete Arrow-Debreu economy. This feature has important implications on macro modelling. Because of the difficulty in introducing money into a macro model in an essential and endogenous manner as in the overlapping types model of this paper, a macro model typically ignores money and studies real allocations without the money factor. The possible inefficiencies of a monetary economy, relative to a complete real Arrow-Debreu economy, may indicate differences in real allocations between the two models.

Recently, cutting-edge ICT technologies such as artificial intelligence, blockchain, edge computing, and the Internet of Things have been applied in various fields to create new services and a new digital era. Along with these technological developments, various policies are being implemented in Korea to transform the country from a "Smart City" to a "Platform City". We can create new services and values by linking with the Smart City Integrated Platform and Smart Housing Platform. This paper defines a linkage scenario between a Smart Housing Platform and the Smart 119 Emergency Dispatch Support Service, one of the Smart City Safety Nets. We propose a data transmission protocol and a metadata schema for data exchange between the Smart Housing Platform and the Smart City Integrated Platform to provide the Smart 119 Emergency Dispatch Support Service.
