This study analyzes the Western rocking chair style of the middle of the 20th century (1945~1970), and investigates academically characteristics from formative and practical points of view. The purpose of this study is to provide basic information on the design and production of the modern Korean rocking chair. In the 20th century, the production of the Western rocking chair displayed principles of both functionalism and optimism. These rocking chairs are constructed of various industrial materials including reinforced plastics, moulded plywood, aluminium, and steel as well as wood. Furthermore, a rocking chair suitable to the human body is made by industrial growth and innovative fabrication techniques such as designer's plastic from military in the First and Second World Wars. In those days, there are many different types of rocker style - traditional, plastics, structural, moulded plywood & bending, metal tubular, and wire mesh. More specifically, through economic prosperity and plastic development, the rocking chair is able to have light and bright colors, which shows sensible formality of the modern and structure.

This research is intended to study literatures relating to western rocking chairs style in early 20th century in order to provide basic data of designs for rockers of today in Korea and investigate characteristics of rocking chair from academic, formative and pragmatic perspectives. During the first half of 20th century, western rocking chairs (1925~1945) embodied actively the simple functionalism concept that furniture design must follow functionality considerations. Therefore, bare wood rocking chairs were without any surface decoration and tubular steel frame rocking chairs often included black leather upholstery in a bold attempt to express exposed structure. And the fact that tubular steel produced such lightweight furniture was crucial importance. Many Modernist designer created curvaceous lines of new pattern changes in their furniture. The structure of Modern rocking chair became all-important, for stylistic as well as functional reasons. Designers equated exposed structure of tubular steel and wooden frame with integrity and rationality and create an equalitarian style of design. Especially, designers in the early 20th century did use various brilliantly colored upholstery and wooden frame with simple forms of modern characteristics.

The purpose of this study is to research and develop poly(p-phenylene)(PPP)-based carbon obtained by pyrolyzing electrochemically prepared PPP as a anode of rocking chair batteries. Disordered carbon materials were obtains by heat-treating of PPP films in a nitrogen atmosphere at 4$0^{\circ}C$ to 110$0^{\circ}C$ for 1 hour. The carbon prepared by heat treatment showed a broad x-ray diffraction peak having characteristics of disordered carbon. Carbon electrodes were charged and discharged at a current density of 0.1㎃/$\textrm{cm}^2$. First discharge capacity of 267㎃h/g and 34% of charge/discharge efficiency were observed from PPP-based carbon prepared at $700^{\circ}C$.
