The researches and discussion for regenerating the deprived urban residential areas are proceeding actively. But urban agriculture is regard as a simple tool for participation of resident and its value as primary industry is discussed in part. Now discussion about increasing the place capital is needed to overcome the existing urban development methods that maximizes the space capital as a new alternative. So this research is to give a theoretical basis for sustainable urban regeneration. It studies the place value improvement through urban agriculture which is applied creative industry convergence. For these, it indicates problems of the methods of existing urban development, reveal the strengths of urban agriculture applied creative industry convergence in the aspect of place value improvement, and suggests a new paradigm for urban regeneration.

This study attempts to identify how the value network of mobile industry has evolved in the value creating process. The longitudinal case study on SK Telecom was conducted by measuring the SK Telecom's investment structure during from 1999 to 2008. Results show that the convergence services based on the advanced mobile networks changed the revenue structure, and enabled SK Telecom to reposition as a media company. For the value creation, SK Telecom's value network has flexibly adapted to convergence environment through dynamic asset reconfiguration.

Banks are preparing the system for the new concept of the 2020's. The framework of the core-banking solution is that various demands must be accommodated. In addition, the development process of new system must solve problems, such as obtaining the economic feasibility and expandability as well as minimizing the risk elements. This study verified the superiority of converging framework by analyzing the framework of new converging core-banking solution that can accommodate the current core-banking solution and future requirements. In addition, the study proposed application methods and the pros & cons of a converging framework. The migration effects and successful elements for changing to a new system are proposed.

We will investigate in depth the reasons why companies have a negative mindset and produce complaints about the internship system itself. On the other hand, we try to find out the success factors of domestic companies that have introduced and operate the exemplary internship system, and prepare policies to disseminate them. In order to do this, I would like to diagnose the problems related to the internship system in the current industry through questionnaires or interviews with existing internship students. It is hoped that this will help the participating students to have a positive mindset about the company and further contribute to the career search and adaptation to the firm from the university to the firm.

In the edge of new jumping up in global market, our construction industry is required to develop a competitive power and new construction market. As a considerable global player, our construction industry and information technology industry are regarded as to achieve more competitiveness and new market by developing fusion technology between information and construction technology. But, practically not only the technologic barrier but unripe developing model, it is time to visualize fusion strategic model and possible area as a constructional point of view. The aim of fusion technology is to increase productivity by reducing labor power and over all life cycle cost and to suggest new market with effective demanding power such as ubiquitous-city. As a successful development model, both the demand driven approach dealing with prompt IT developing speed and a circular leading model boosted by leading group will be key factors.

As interest in advanced countries regarding the convergence technology development increases, a methodology for identifying the core convergence technology that has a large spill-over effect on the technology and industry is required for the nation's competitiveness enhancement in the convergence technology field. Based on patent citation network analysis using 1,124 USPTO patents in the ICT convergence technology field of the smart factory, this study examined the proposed heterogeneous technology convergence index as a tool for measuring the convergence characteristics of the spillovers compared to other indexes (i.e. other sector ratio index and homogeneous technology convergence index). The proposed heterogeneous technology convergence index was used to investigate core technology sectors among ICT technology sectors of smart factory identified by government ministries. Results found 6 core ICT convergence technology sectors including the manufacturing execution analysis application sector. Also, this study conducted blockmodeling analysis using the IPC codes of patents in the manufacturing execution analysis application sector, and identified that the blocks representing the electronic communication and electric digital data processing technology sectors (Block 3 & 4) are related technology sectors which can be converged with core technology. Based on the findings, the implications for the convergence technology development planning of the smart factory field are discussed.

Microalgae, as photosynthetic organisms, possess the ability to produce a diverse array of bioactive compounds. This study focused on the transformant Chlamydomonas reinhardtii dZL and subjected it to cultivation under varying light intensities (60, 120, 180, and 240 µmol/m²/s). Our aim was to assess the impact of light intensity on both microalgal biomass and carotenoid production. The cultivation took place in 80 mL bubble column photobioreactors, specifically the Multi-cultivator. Notably, the culture exposed to 240 µmol/m²/s exhibited the most rapid cell growth, surpassing even the cell concentration achieved at 180 µmol/m²/s by day 8. A detailed analysis of the specific irradiance rate over time unequivocally revealed a sharp decline in growth rates when the rate fell below 2 × 10^-10 µmol/cell/s. Although the culture with 60 µmol/m²/s yielded the highest carotenoid content (1.2% of dry weight), the culture exposed to 240 µmol/m²/s recorded the highest carotenoid concentration at 8.9 mg/L owing to its higher biomass. Our findings reveal the critical importance of maintaining a specific irradiance rate above 2 × 10^-10 µmol/cell/s to enhance biomass and carotenoid productivity. This study lays the groundwork for defining optimal light intensity conditions applicable to mass culture systems, with the objective of augmenting C. reinhardtii biomass and optimizing carotenoid productivity.

IT관련 제품(데스크톱, 노트북, 스마트폰 등)과 자동차, 선박, 자판기 등 기계(Machine)관련 제품과의 융합이 이뤄지고 있으며 각 장비간의 통합 융합으로 변화됨에 따라 네트워크 시스템과 S/W에 대한 보호가 더욱 어려워지고 있는 상황이다. 이러한 문제는 산업계 내에서 다양한 그룹의 사용자들이 다양한 장비를 사용하므로 더 복잡해지며, 결국에는 수많은 기계장치의 사용자 수준에 따라 다른 수준의 보안이 필요하게 된다. 본 논문에서는 차세대 이동통신의 한분야인 M2M(Mahcine to Machine) 통신에 대한 동향 소개와 M2M의 보안 위협요소 분석을 통한 키관리 기법과 Threshold 암호 기법을 소개한다.

In order to identify and analyze potential aviation safety hazards, analysis of aviation safety report data must be preceded. Therefore, in consideration of the provisions of the Aviation Safety Act and the recommendations of ICAO Doc 9859 SMM Edition 4th, personal information in the reporting data and sensitive information of the reporter, etc. It identifies the scope of de-identification targets and suggests a method for applying de-identification processing technology to personal and sensitive information including unstructured text data.
