This study aims at clarifying the planning methods and historical significance of Park Byung-Joo's New Seoul Blank Plan(1966) in the context of South Korea's Urban Design during the 1960-1970s. In addition, it also tries to reveal how the planner's ideas were transformed into realized urban projects in Korea. By the comparison of the New Seoul Blank Plan and these projects, we can come to understand how the new concepts of urban planning such as CIAM's planning principles, Neighborhood Unit Theory, New Town plan and green belt concept were adapted to Korean society in the 1960s and 1970s.

A simple regioselective synthesis of cinnoline derivatives was achieved by a one-pot three component synthetic methodology. New substituted 7,8-dihydrocinnolin-5(6H)-ones are prepared via one-pot three component reaction of arylglyoxals with 1,3-cyclohexanedione and dimedone in the presence of hydrazine hydrate in moderate to good yields.

Korea Power Exchange has successfully performed the Long-term Electricity Demand Forecasting. Recently there is a lot of change in electricity industry sector; the national master-plan for green gas emission reducing, rise of smart-grid, and new trend of electricity consumption, and it is becoming painful challenging for demand forecasting. In new circumstance the demand forecasting is required more flexible and more accurate.

This paper proposes a new absorbing boundary condition(ABC) for the FDTD simulation of waveguide problems. It is based on the exact analytic expression for the time domain EM wave propatation in the waveguide. The ABC derived from the expression has a convolution form whose kernel (the discrete Green's function) has a simple, closed form formula. Also, it is applicable to the wide variety of waveguide types with conducting boundaries and complex cross-sectional shapes.

Five species in the genus Thalia of the family Salpidae are described: Thalia cicar van Soest, 1973, Thalia democratica (Forskal, 1775), Thalia orientalis Tokioka, 1937, Thalia rhomboides (Quoy and Gaimard, 1824), and Thalia sibogae van Soest, 1973. All of these species are new to the Korean fauna. A key to the Korean Thalia species is provided.

We introduce a new biharmonic kernel for the upper half plane, and then study the properties of its relevant potentials, such as the convergence in the mean and the boundary behavior. Among other things, we shall see that Fatou's theorem is valid for these potentials, so that the biharmonic Poisson kernel resembles the usual Poisson kernel for the upper half plane.

The discussion of this study is that we proposed a new construction to improve the potency of LCOS projection monitor. We suggest a new construction that uses special optics coating to reduce the green channel and obtains a purer white field. Compared with the voltage method to adjust on the monitor, we can get higher contrast gradient.

The achievement of high density at reasonable cost is one of the major challenges of the P/M industry. One of the key factors contributing to the compressibility of a mix is the lubricant. New experimental lubricants enabling higher green density by conventional compaction or temperature-controlled die compaction were identified. The compaction and ejection characteristics of these new lubricants as measured with a fully instrumented lab press are presented and compared to that of conventional lubricants.

Only do we have an earth! It is crucially important to improve our living environment and keep the sustained development of a city in the limited space. Some concrete examples will be analysized in the paper, elaborating upon how to make full use of roof space and various plants to create a better green-space. To create different activity space with unique characteristics for people, various plants, roof-space, water and buildings in the style of garden should be use when local conditions and design requirement should be considered.
