R&D into future technologies should be conducted in conjunction with technological innovation strategies that are linked to corporate survival within a framework of information and knowledge-based competitiveness. As such, future technology strategies should be ensured through open R&D organizations. The development of future technologies should not be conducted simply on the basis of future forecasts, but should take into account customer needs in advance and reflect them in the development of the future technologies or services. This research aims to select as segmentation variables the customers' attitude towards accepting future telecommunication technologies and their value orientation in their everyday life, as these factors wilt have the greatest effect on the demand for future telecommunication services and thus segment the future telecom service market. Likewise, such research seeks to segment the market from the stage of technology R&D activities and employ the results to formulate technology development strategies. Based on the customer attitude towards accepting new technologies, two groups were induced, and a hierarchical customer segmentation model was provided to conduct secondary segmentation of the two groups on the basis of their respective customer value orientation. A survey was conducted in June 2006 on 800 consumers aged 15 to 69, residing in Seoul and five other major South Korean cities, through one-on-one interviews. The samples were divided into two sub-groups according to their level of acceptance of new technology; a sub-group demonstrating a high level of technology acceptance (39.4%) and another sub-group with a comparatively lower level of technology acceptance (60.6%). These two sub-groups were further divided each into 5 smaller sub-groups (10 total smaller sub-groups) through two rounds of segmentation. The ten sub-groups were then analyzed in their detailed characteristics, including general demographic characteristics, usage patterns in existing telecom services such as mobile service, broadband internet and wireless internet and the status of ownership of a computing or information device and the desire or intention to purchase one. Through these steps, we were able to statistically prove that each of these 10 sub-groups responded to telecom services as independent markets. We found that each segmented group responds as an independent individual market. Through correspondence analysis, the target segmentation groups were positioned in such a way as to facilitate the entry of future telecommunication services into the market, as well as their diffusion and transferability.

The adoption of smart factories and smart manufacturing as strategies to enhance competitiveness and stimulate growth in the manufacturing sector is vital for a country's future competitiveness and industrial transformation. The government has consistently pursued smart manufacturing innovation policies starting with the Manufacturing Innovation 3.0 strategy in the Ministry of Industry. This study aims to identify policy areas for smart factories and smart manufacturing based on technical standards. Analyzing policy areas at the current stage where the establishment and support of domestic standards aligning with international technical standards are required is crucial. By prioritizing smart manufacturing process areas within the industry, policymakers can make well-informed decisions to advance smart manufacturing without blindly following international standardization in already well-established areas. To achieve this, the study utilizes a hierarchical analysis method including expert interviews and importance-performance analysis for the five major process areas. The findings underscore the importance of proactive participation in standardization for emerging technologies, such as data and security, instead of solely focusing on areas with extensive international standardization. Additionally, policymakers need to consider carbon emissions, energy costs, and global environmental challenges to address international trends in export and digital trade effectively.

In this paper, we propose the mechanism of China's green financial policy on renewable energy industry development implemented in different pilot zones. By utilizing the synthetic control method, this paper examines the differences in the effect of green financial policy before and after its implementation. The results demonstrate that green financial policy can significantly reduce traditional energy consumption while promote the renewable energy industry development simultaneously. Furthermore, the effects across different regions reveal that the impacts of green financial policy are pronounced in selected pilot zones, with Shanghai and Chongqing standing out the most while Gansu province performs the worst. The analysis also figure out that green financial policy stimulates the expansion of regional financing scales, resource endowment, and technological innovation as well.

This study examined changes in the energy landscape, focusing on the photovoltaic module carbon certification system. As the global photovoltaic market has been reorganized around Chinese companies, the South Korean government has pushed to strengthen the competitiveness of the nation's photovoltaic industry. However, a limitation remains in that the government-led effort was not sufficient to bring about dynamic changes in the energy landscape. Against this backdrop, this study explored the stages leading to the multi-level perspectives of "macro-environment, socio-technical regime, and niche" to track the process of the government and domestic photovoltaic companies as part of a socio-technical regime responding to global market changes. In particular, this study raised an issue with the conceptual discussion of multi-level perspective, which placed a particular emphasis on the rate of change at each level and the niche in which innovative experiments take place, and thus attempted to fill this gap by tracking the energy landscape that varies differently from space. These spatial discussions can track different carbon emissions coefficients and industrial characteristics for each country, and have a higher level of explanatory power for the system thus constructed. In addition, through discussions on the problems and implications of the government-led introduction of renewable energy policies, this study suggests the need to create and implement a field-oriented system.

The increasing demand for metallic minerals due to global growth and the continued exploitation of near-surface minerals requires safe and efficient ways to mine ores present in deep mines. In deep mines, stresses concentrated around the cavity increase, which can lead to problems such as induced seismicity and rockbursts. In addition, the transfer of energy from blasting to deeply located faults can cause fault slip, which can lead to earthquakes, and controlling these events is key to deep mining methods. In this technical report, we will introduce the Underhand Closed Bench (UCB) mining method, which can control possible accidents and increase productivity when mining in deep mines.

바낙 공기 급기(UFAD, underfloor air distribution)는 사무실과 상업 건물의 공조를 위하여 바닥 하부 공간을 사용하는 혁신적인 기술이다. 북미에서는 UFAD가 기존 천장 공기 급기 방식에 비하여 많은 장점을 지니므로 그 수요가 날로 증가하고 있다. 잘 설계된 UFAD 시스템은 다음과 같은 장점을 지닌다. - 건물의 용도 변경에 따픈 유연성이 우수하므로 건물의 생애 주기 비용을 감소시킨다. - 개별 쾌적성 제어가 가능하므로 온열 쾌적성, 거주자의 만족도 그리고 생산성을 향상시킨다. - 거주자주변에 직접 선선한 공기를 공급하므로 환기 효율, 실내 공기질 그리고 건강 상태를 향상시킨다. - 이코노마이저 운전, 온도 성층화 그리고 낮은 정합 운전에 의하여 에너지 비용을 감소시킨다. - 설비 공간이 축소되고 표준 철골 구조에서는 콘크리트 구조체 변경이 가능하므로 새 건축 공법에서는 충고를 감소시킬 수 있다. 1995년까지만 해도 UFAD는 파격적인 설계 기법이라고 여겨졌지만, 이제 설계자와 건축업자들은 2004년까지 신축되는 사무용 건축품의 35%는 바닥을 높인 기법이 적용되며 이 중 반 정도가 UFAD를 채택할 것이라고 예측하고 있다. 2000년 2억불이라고 추정되던 바닥을 높이는 건축의 시장 규모가 2004년에는 최소 10억불이 되리라고 예측된다. UFAD는 기본 연구에 의한 정립된 표준화된 설계 기법과 지침이 아직 마련되지 않았음에도 불구하고 현재 설계, 시공되고 있다. 이라한 경향은 펄수적인 연구가 수행되어 관련 업계가 지식과 경험을 충분히 쌓기 전까지는 계속될 전망이다. 본고는 시스템 설계와 운영의 주요한 특징, 기존 방식과 비교하여 지니고 있는 잠재적인 장점, 한계와 기술 개발의 필요성, UFAD 기술 개발을 위하여 계속적으로 요구되는 연구 분야 등을 서술함으로써 현재 UFAD 기술에 대한 평가를 한다.
