This study focuses on the network externality effect related to the platform supplementary services. This study designs the network externality of platform and suggests a supplementary service adoption model. Additionally, this study examines the moderating effect of demand forecasting for the platform. Using AMOS program, a structural equation modeling has been used to analyze the research model. The findings can be summarized as follows : First, we find out the structural relationship among the factors (usefulness, perceived value, purchase intention) affecting adoption of the supplementary services. Second, positive perception of platform flow can promote the platform interaction. Third, positive perception of present users based on platform can arouse friendly evaluation in the platform interaction. Fourth, loyalty to the platform brand can improve the perceived usefulness of supplementary services, but cannot lessen the resistance to supplementary service cost. In addition, the moderating effects of demand forecasting for the platform in the path leading from platform factors to supplementary service factors were identified. In conclusion, traditional brand strategy may be effective in platform marketing activities but the extent of performance in the strategy can appear to be quite different. Therefore, taking the relationship with network externality into consideration should be involved in the marketing strategy in platform.

The configuration of injection molded part can be classified into primary feature and supplementary feature. Even though supplementary features such as ribs, snap fits and bosses make mold more complicated, which cause the increasement of the mold cost, supplementary features should be attached to primary features because of assembly, reinforcement, moldability and other functional purposes. But it is not easy for novice designers to design them appropriately because of the profound knowledge related to Injection molding. In this paper, the intelligent design tool called ISFD(Intelligent Supplementary Feature Designer) which supplies easy, simple, time and cost-effective design method has been studied and developed. A knowledge-based design system is a new tool which enables the concurrent design and CIM with integrated and balanced design decisions at the initial design stage of injection molding.

This paper proposes supplementary control of conventional coordinated control of a power plant which directly affects network frequency. The supplementary control with dynamic matrix control is applied for 1000 MW power plant with ultra-supercritical (USC) once-through boiler. The supplementary control signal is added to the boiler feedforward signal in the existing coordinated control logic. Therefore, it is a very practical structure that can maintain the existing multi-loop control system. This supplementary controller uses the step response model for the power plant system, and on-line optimization is performed at every sampling step. The simulation results demonstrate the effectiveness of the proposed supplementary control in a wide operating range of a practical 1000 MW USC power plant simulator. These results can contribute the stable operation of power system frequency.

BACKGROUND: Light-emitting diodes (LEDs) with lower electric cost and the specific wavelength have been considering as a novel light source for plant production in greenhouse conditions as well as in a closed culture system. Supplementary lighting for day-length extension was considered as light intensity, light quality, and/or photoperiod control on plant growth and development. Effects of supplementary blue or red LED radiation with lower light intensity on growth of Ageratum (Ageratum houstonianum Mill., cv. Blue Field), African marigold (Tagetes erecta L., cv. Orange Boy), and Salvia (Salvia splendens F. Sello ex Ruem & Schult., cv. Red Vista) were discussed during sunrise and sunset twilight in the experiment. METHODS AND RESULTS: Supplementary lighting by blue and red LEDs for 30 (Treatment B30; R30) or 60 (Treatment B60; R60) min. per day were established in greenhouse conditions. Photosynthetic photon flux for supplementary radiation was kept at $15{\mu}mol\;m^{-2}\;s^{-1}$ on the culture bed. Natural condition without supplementary light was considered as a control. The highest shoot and root dry weights were shown in African marigold exposed by red light for 60 min. per day. Supplementary blue and red lighting regardless of the radiation time significantly stimulated development of lateral branches in African marigold. Stem growth in Ageratum and Salvia seedlings was significantly promoted by red radiation as well as natural light. CONCLUSIONS: Extending of the radiation time at sunrise and sunset twilight using LEDs stimulated reproductive growth of flowering plant species. Different characteristics on growth under supplementary blue or red lighting conditions were also observed in the seedlings during supplementary radiation.

This research surveyed oriental medicine therapies currently used in oriental medicine circles by referring to oriental medicine books-based existing traditional authentic therapies, as well as market-sold supplementary therapy-related ordinary health books and Internet information, and supplementary therapy-related dissertations, reviewed the fundamental operating significance of these therapies, and pursued their clinical operating measures based on their clinical information as follows Various therapies currently used in oriental medicine circles are categorized into authentic therapies and supplementary therapies in oriental medicine. Authentic therapies in Oriental medicine are based on bodily self-vitality abilities, pursue positive methods of treating diseases, and include medication therapies, acupuncture therapies, and external therapies. Supplementary therapies in oriental medicine are based on bodily self-vitality abilities, pursue indirect methods of treating diseases, and consist of lifestyle therapy and body management therapy. Authentic and supplementary therapies in Oriental medicine are used either separately or together according to clinical treatment methods. In treating diseases, clinical operating methods exclusively based on traditional authentic therapies and supplementary therapies include Donguibogam (anthology of ancient oriental medicine), Uihakipmun (introduction to medicine), Somun school, and bodily acupuncture according to diagnoses of symptoms, as well as sasangbang (prescription based on four types of bodily constitution), myeongribang prescription, hyeongsangbang prescription, and bodily constitution-based acupuncture according to diagnoses of bodily constitutions. In clinical operation of Oriental medicine, supplementary therapies are parity duplicated dy alternative medicine. However, given patients' needs and clinical practicality, Oriental medicine circles should establish a system based on the fundamental viewpoint of Oriental medicine theories, and corresponding policies should also be researched.

The purpose of this study was to analyze the current implementation states of the differentiated curriculum at the middle school and to propose ways to improve it. For that purpose this study conducted a survey and had the interviews with the middle school mathematics teachers. The items of survey and interviews consisted of the two main parts: current states and needs about the special supplementary courses and enriched supplementary courses. The results showed that there were discrepancies between the current states and the needs of the differentiated curriculum. This means the efforts to improve the current states are needed. The strategies for improving the implementation of the differentiated curriculum are as follows: 1. The use of various standards including the subject-achievement level and students' or parents' opinions is needed in selecting the students of special supplementary course. 2. More relevant special supplementary materials need to be developed and utilized. 3. The ability grouping is recommended for the differentiated instruction. 4. The deliberation of developing the enriched and supplementary texts is requested. 5. The study for differentiated evaluation of students is demanded.
