The most significant degradation problem of PLED has been described and new buffer layer material aimed for use as HTL in PLED to solve this issue has been studied. This approach has enabled the increase of the green device efficiency (${\sim}$2x) and lifetime (${\sim}$5-6x).

In this paper, we propose a workflow framework for the integrated logistics systems. We modelled the logistics activities into workflows, which allow clear specification and flexible modification of business processes. To specify workflows, we used petri-net that is extended to handle with information flows. A framework to implement the integrated logistics system using workflow management technology is proposed. Since logistics is closely related with other parts of enterprise such as manufacturing and accounting, the framework could capture a rich features required for enterprise-wide systems.

This work has been carried out to find the ideal operating conditions for solar vacuum tube collectors which are widely used at present. Various types of solar collectors including a flat plate one were experimentally tested and examined to determine their thermal efficiencies and operating characteristics. Generally, solar vacuum tubes can be classified into two groups according to their design features. Of these, one is characterized by the insertion of a metallic device(such as a finned heat pipe) in an evacuated glass tube for the collection and transportation of solar energy. The other utilizes double glass tubes where the smaller one is contained inside the bigger one and soldered to each other after the small gap between them is evacuated. Both of these solar collectors are designed to minimize convection heat losses by removing the air which is in direct contact with the absorber surface. The performance of the former type can be readily analyzed by applying the relevant correlations developed for flat plate solar collectors. This has been demonstrated in the present study for the case of a solar collector where a heat pipe is inserted in an evacuated tube.

This thesis is studing Kim Chi-in's Life and Confucianism-Buddhism-Taoism-Unity of Namhak lind on Jinan in Junbuk. He combined thought of Confucianism-Buddhism-Taoism and drawed up religious doctrine, after spotting internal and external troubles of nation. Kim Chi-in was influenced by Lee Un-gyu's thought of Confucianism-Buddhism-Taoism-Unity. He spoke with emphasis of Tao in doctrine through religious experience. The root of Tao originates in heaven. Although Tao was divided according to Confucianism, Buddhism and Taoism for the human's aspect of thought, it is ultimately the one. In time on explaining the one, he invoked 'eum(陰)', 'yang(陽)', 'che(體)'와 'yong(用)' as concepts of Neo-Confucianism. This ididn't incline to one side of Confucianism, Buddhism and Taoism. While he spoke with emphasis on Confucianism's ethics of 'yang' and 'yong' with Buddhism and Taoism's divine of 'eum' and 'che' as the center, he want to find pivot of thought. He especially seeked Younggamu(詠歌舞) of sing and dancing on training mind and body. This was that he let the people and scholars in retirement demand realization of Tao and aim at real virtue. The study of Kim Chi-in's thought and religion of Confucianism-Buddhism-Taoism-Unity will be an opportunity look around his identity for the traditional native thought and universality.
