Korea has exerted her efforts to assimilate nuclear power technology, and reportedly localized 95 percent of nuclear power technology by 1995. This paper investigates the evolution of nuclear power program in Korea to exploit the development process of the nuclear power industry and key factors for the technological localization of nuclear power plant. In developing countries, an imitative catching-up process can be shown as a course for developing the absorptive capacity of foreign technology, which depends on prior knowledge base and the intensity of effort. The process of technological learning consists of five stages including preparation, implementation of foreign technology, acquisition of peripheral technology, acquisition of core technology, and improvement f foreign technology. Moreover, this paper discusses six essential factors that have influenced the successful achievement of technological localization of nuclear power plants in Korea. They include the role and strategies of the government, the leading role of utility firm, the development and cooperation of the related organizations, the development of human resources and their efforts, market conditions and the assistance of foreign donors, and social conditions. Finally, this paper discusses about implications offered by the Korean experience for other developing countries.

Recently, the rapid progress of Internet and Network affects engineering design environment as well as Business fields to utilize Web technologies to enhance it's competitively in the world. In product development, experts and organizations actually taking part in the design process are often geographically dispersed. Furthermore, different divisions and businesses often have heterogeneous CAD/CAE systems and methods for expressing product data, and addressing this heterogeneity creates additional costs and causes longer development periods. To ensure successful collaboration in the design process, it is therefore imperative that distributed CAD, CAE, and other related systems be managed in an organic and integrated manner from the initial stages of product development. Therefore, this study suggests Web-based MDO(Multidisciplinary Design Optimization) framework to support interfacing and the collective use of design and analysis tools.

Crosslinked agar-g-poly(acrylic acid) (x-agar-g-PAA) super absorbent with a water absorbency ($Q_{H2O}$) of approximately 660 g/g was synthesized by the copolymerization of agar with an acrylic acid monomer. KPS and MBA were used as the initiator and crosslinker, respectively. Grafting was performed in air. Infrared spectroscopy was used to identify the product of copolymerization. The optimum conditions to synthesize the x-agar-g-PAA superabsorbent were 0.1 g of agar, 0.1 g of the KPS initiator, for 15 min; 50% AA monomer, 0.005 g of the MBA crosslinker, for a propagation time of 5 min; and 1 M NaOH for 15 min to allow for saponification. The reaction temperature was $80{^\circ}C$.

최근 XML표준기술을 활용한 웹서비스는 기업내 및 기업간의 정보시스템을 통합하는데 발생되는 문제점을 해결해 주는 차세대 e-비즈니스의 기반으로 급부상하고 있다. 정보기술이 지속적으로 변화하기 때문에 특정 기술에 기반한 시스템을 정보 기술 변화에 맞게 통합, 변화, 유지하는 것은 지속적인 문제로 고려되고 있다. 이러한 문제점을 해결하기 위해 OMG는 MDA(Model Driven Architecture)라는 새로운 소프트웨어 아키텍처를 제시하였다. MDA는 기존의 개발 절차에서 분석모델인 플랫폼 독립적인 모델(PIM, Platform Independent Model)을 구축하고 이를 기반으로 설계모델인 플랫폼 종속적인 모델(PSM, Platform Specific Model)로 자동 변환하는 프로세스를 가진다. 이러한 자동 변환을 통해 여러 플랫폼을 쉽게 지원하고 개발자의 입장에서는 코드 작성에 소요되는 시간을 줄일 수 있으며 개발 프로세스의 측면에서도 품질관리를 수월하게 할 수 있다. 이 MDA의 개발 프로세스를 웹서비스개발 프로세스에 적용하면 MDA의 PIM에서 목표플랫폼으로 웹서비스를 선택하고 웹서비스 모델인 WSDL로 PSM을 표현할 수 있다. 본 논문에서는 웹서비스 공급자와 요청자가 웹서비스를 개발하거나 통합할때의 절차를 분류하여 웹서비스 개발 프로세스유형을 만들고 웹서비스 개발시 MDA개발 프로세스를 적용하여 웹서비스공급자와 요청자가 참조가능한 새로운 웹서비스 개발 프로세스를 제안한다.

An Internet of Things(IoT) technology which provides intelligent services by combining context-awareness based intelligences, inter-communication is made of between things and things or between things and person through the network connected with intelligent things is spreading rapidly. Especially as this technology is converged into smart device, mobile, cloud, big data technologies, it is applied into various domains. Therefore, this is different from existing Web or Mobile Application. New types of IoT applications are emerging by adapting IoT into Web or mobile. Because IoT application is not only focused on software but also considering hardware or things aspect, there are limitations existing development process. Existing development processes don't consider analysis and design techniques considering both hardware and things. We propose not only a meta-model for development process which can support IoT application's development but also meta-models for main activities in this paper. Especially we define modeling elements by using UML's extension mechanisms, provide development process, and suggest design techniques how to apply those elements into IoT application's modeling phase. Because there are many types of IoT application's type, we propose an Android and Arduino-based on IoT application as a case study. We expect that proposed technique can be applied into many of various IoT application development and design with a form of flexible and extensible as well as main functionalities or elements are more concretely described. As a result, it brings IoT application's flexibility and the effect of quality improvement.

Three species of the family Processidae, Hayashidonus japonicus (De Haan, 1844), Processa sulcata Hayashi, 1975 and Processa zostericola Hayashi, 1975 described with illustrations from Korea. Two of these species, H. japonicus and P. zostericola, represent new records for the Korean carcinological fauna. The genus Hayashidonus included the single species, H. japonicus is distinguished from other genera of Processidae by the broadly triangular rostrum, the obscure or absent dorsolateral spines of the telson, and the exceptionally long molar process of the mandible. Two species of the genus Processa, P. zostericola and P. sulcata are distinguishable each other by presence or absence of an obtuse process of the basicerite of antenna on the anteroventral margin. The basicerite of antenna arms with the obtuse process in P. zostericola, while in P. sulcata the basicerite of antenna lacks the process but is smooth on the ventral margin. A key to these species is presented.

In this study the amorphous carbon films were deposited by PECVD at the substrate temperature range of 250 to $600^{\circ}C$, and the process conditions of higher and lower precursor flow rate, respectively. The temperature was a main parameter to control the density and mirco-structures of carbon films, and their's properties depended with the process temperatrue are changed by controlling precursor flow rate. The precursor feeding rate affect on the plasma ion density and a deposition reactivity. This change of film properties was obtained the instrinsic stress, FT-IR & Raman analysis, refractive index (RI) and ext. coef. (k) measured by ellipsometer. In the process conditions of lower and higher flow rate of precursor it had a different intrinsic stress as a function of the substrate temperature.

In this study, we investigated the deposition behavior and the etch resistivity of plasma polymerized carbon hardmask (ppCHM) film with the variation of process temperature. The etch resistivity of deposited ppCHM film was analyzed by thickness measurement before and after direct contact reactive ion etching process. The physical and chemical properties of films were characterized on the Fourier transform infrared (FT-IR) spectroscope, Raman spectroscope, stress gauge, and ellipsometry. The deposition behavior of ppCHM process with the variation of temperature was correlated refractive index (n), extinction coefficient (k), intrinsic stress (MPa), and deposition rate (A/s) with the hydrocarbon concentration, graphite (G) and disordered (D) peak by analyzing the Raman and FT-IR spectrum. From this experiment we knew an optimal deposition condition for structure of carbon hardmask with the higher etch selectivity to oxide. It was shown the density of ppCHM film had 1.6~1.9 g/cm3 and its refractive index was 1.8~1.9 at process temperature, $300{\sim}600^{\circ}C$. The etch selectivity of ppCHM film was shown about 1:4~1:8 to undoped siliconoxide (USG) film (etch rate, 1300 A/min).

This study proposes an entrepreneurship education process for fashion product start-ups through rewards-based crowdfunding. It examines issues such as: the general concept of crowdfunding and the pros and cons of rewards-based crowdfunding, the detailed curriculum plans in a chronological order for the regular class development, and the presentation of a visual plan to show the whole process. An entrepreneurship education process is developed in 13 steps: research on crowdfunding market, prototype plan, prototype production, story development, visual contents development, rewards development, project evaluation, public schedule & service setting, period setting & start funding, community management (Q&A), funding ends & deposit, complete manufacturing & start delivering, and the final information disclosure & open the next project plan. This research is intended to investigate rewards-based crowdfunding as a new paradigm of entrepreneurship and apply entrepreneurship education in fashion product development. However, it is limited to studying the Wadiz crowdfunding platform in Korea. Therefore, we propose a case study on various crowdfunding platforms in Korea, a case study on entrepreneurial curriculum application, and a follow-up study on the possibility of entry into an overseas crowdfunding platform.
