Purpose: In this study, we revealed the influence of customer buying factors in the purchase process of eco-friendly product. Especially, we focused on the information acquisition, alternative evaluation, and after-purchase activity process based on Korea-China customer's survey. Methods: In the information acquisition process, we investigate the channels of information acquisition about eco-friendly product, a reliability of information, and an impediment of acquiring product information. At the stage of alternative evaluation, we extract various causes that affects pre-purchasing process and perform the AHP analysis to identify critical causes. At last, we compare several factors which affects before and after purchasing process. Results: Especially, an average utilization and cognition score of eco-friendly products of Chinese consumers is higher than Korean consumers' score. In addition, critical buying factors of Korean consumers are a product quality, an evaluation of existing users. However, that of Chinese consumers are safety of products and environmental benefits of products. Conclusion: In recent years, as the rapid economic development of China, environment pollutions like heavy smog and yellow dust have been occurred frequently. In that manner, Chinese consumer's environmental consciousness is rapidly increasing; not only try to be active participant in eco-friendly activities, but also eco-friendly purchasing activities. In addition, Chinese consumers recognize eco-friendly products as good products made with advanced technology.

생산성 향상과 효율적인 프로세스 관리는 기존 업무의 문제점을 올바르게 파악하는 것에서부터 시작한다. 또한 데이터 수집에서 필요한 정보를 도출하는 데 많은 시간이 소요될 경우 고객의 요구와 수요를 충족시키고 업무의 효율성을 높이기 위한 지속적인 프로세스 관리가 더욱 어려워진다. 본 논문은 실시간 정보획득 기술의 도입을 통해 제조공정 관리상 발생 가능한 여러 문제점을 개선하기 위한 방안과 기초적 의사결정을 위한 상황인지(Context awareness) 시스템을 제시하는 것을 목적으로 한다. 공정 작업 중 획득한 데이터를 바탕으로 각 작업을 자동으로 분류하는 판단규칙을 제시하여 제조 현장에서의 상황인지를 구현하고자 하였다. 그리고 제안하는 개념과 구조를 작업자가 신속하게 문제를 파악하고 지시사항을 전달할 수 있는 사례를 기본적 시스템으로 구현하였다. 생산요소 객체 및 정보시스템의 데이터 일치와 공정에 대하 지속적이 모니터링을 통해 비효율적 자원 할당 및 공정 지연을 측정하고 해결하며 가시성을 높여 업무 효율을 지속적으로 향상시킬 수 있을 것이다.

The system engineering should be actively applied to successfully develop a complex and advanced weapon system, because the system engineering uses a multidisciplinary approach. Therefore, this study proposed a system engineering process for a successful weapon system development. According to the national standard policy, an IPT aspect system engineering standard must adapt the ISO/IEC/IEEE 15288. It also asks for tailoring with considering the IPT characteristics as a weapon system acquisition institution. The IPT aspect system engineering process to acquire a weapon system can be expressed with 3 process groups (Agreement, Technical Management, Technical) and 20 processes. There was a need for an institutional framework to hire retired experts from related organizations as consultants to apply the low-cost and high efficiency system engineering in the weapon system acquisition field.

Transillumination system used by radiation is widely applied to industrial imaging system. In this study, the linear detector array constructed with scintillator and pin diode, and a multi-channel data acquisition system was developed for precision inspection of end-milling. The detector module consists of $16-CdWO_4$crystal scintillator and photodiode array. The detector and data acquisition system was applied to precision inspection of end-mill and the images of the end-mill were successfully reconstructed. The total system can analyze the Detector Quantum Efficiency(DQE) of each system. The performance of developed photodiodes equipment was compared with each other for different crystal geometry and its characteristics. Finally fine details of the end-mill phantom were constructed for industrial application. The image acquired contains several objects on a real time data transfer and the linear X-ray scanning system can be applied to many fields of a industry.

This study focused on the role of prefabricated speech (routines and patterns) in the L2 acquisition process. The data for this study consisted of spontaneous speech samples and various observational records of three Korean children learning English as L2 in a nursery school. The specific questions addressed here were: (1) What routines, patterns, and creative constructions did the children use? (2) What was the general trend in the three children's use of routines, patterns, and creative constructions over time? The data were collected over a period of one school year by observing the children in their school. The findings were discussed from the perspective of human information processing. This study found that prefabricated speech played a significant role in the three children's L2 acquisition. The automatic processing of prefabricated speech appeared to enable the children to reduce the burden on their information processing systems, which allowed the saved resources available for other language development activities. Also, the children's language development was evident in their increase in the use of patterns. The children were moving from heavy dependence on wholly unanalyzed routines to increased use of partly unanalyzed patterns. This increased control was the result of an increase in procedural knowledge.

A novel high channel efficiency transceiver based on a fast acquisition frequency synthesizer has been designed. The direct digital synthesis (DDS) technique is applied and a simple memory look-up table is incorporated to expedite channel acquisition. The technique simplifies the frequency control process in the transceiver and thus reduces the channel switching time. As a result, the channel efficiency is improved. The designed transceiver is ideal for frequency hopping mobile communication applications.

This paper described a replica-delay adaptive lock-acquisition scheme for high-speed DLLs. The proposed scheme provides the fast and correct locking cycle that is variable according to the magnitude of the arbitrary replica delay (fixed delay). The scheme guarantees the wide operation range and the fast lock-aquisition time. It has been confirmed by HSPICE simulations in a 0.35${\mu}{\textrm}{m}$ CMOS process.
