This paper reports the deposition of a metal line using a multilayer stack and laser-induced forward transfer (LIFT) using a low cost continuous wave blue laser with a wavelength of 450 nm. The donor structure was composed of a light-to-heat (LTH) layer, a release layer, and a transfer layer in series. Amorphous silicon as the LTH layer absorbs photon energy and converts it to heat. A release layer was melted so that a silver transfer layer would be transferred to the receiver substrate. The transferred silver layer showed reasonable physical and electrical characteristics. A low cost fine linewidth metal layer could be achieved using this modified LIFT technique and blue laser.

Extraskeletal osteosarcoma (ESOS) is a malignant soft tissue neoplasm producing osteoid, without any continuity with the bone or periosteum. Primary ESOS presenting in the mediastinum is an extremely rare, yet aggressive malignant tumor associated with a poor prognosis. We report a case of primary ESOS arising from the thymus in a 63-year-old male patient.

A fat body-specific glutathione S-transferase cDMA was cloned from the spider, Araneus ventricosus. The cDNA encoding A. ventricosus glutathione S-transferase (AvGST) is 645 base pairs long with an open reading frame of 215 amino acid residues with a calculated molecular weight of approximately 24 kDa. Northern blot analysis showed the tissue-specifically expression of AvGST in the A. ventricosus fat body.

A pulmonary artery periadventitial hematoma is a rare complication of a Stanford type A intramural hematoma. As the proximal ascending aorta and pulmonary artery share a common adventitial layer, extravasated blood from the intramural hematoma in the ascending thoracic aorta may extend to beneath the adventitia of the pulmonary artery. The authors describe a case involving a 66-year-old male with acute chest pain who presented with a pulmonary artery periadventitial hematoma associated with a Stanford type A intramural hematoma.

In this paper, we propose the bistability the bistability in a chiral-splay nematic liquid crystal cell, which is obtained by adding a chiral additive to a splay cell and introduce a novel switching method for the bistable chiral-splay nematic cell in order to transit the LC director between the non-twisted state with splay and the 180$^{\circ}$ twist state.

Recently, universities have applied a living lab as a user-led innovation model. This study analyzed two cases, British Columbia University, and D University. They are trying to change current provider-centered and expert-centered education model which encounters the limitations. To deriving the characteristics of university living lab, we analyzed the background, goals, methods, and implications of each case. The University of British Columbia operated a living lab centered on university buit-in environment. Students and faculty members participated in the living lab as proconsumers. D University operated a living lab as part of industry - academia cooperation and regional cooperation. The local community was set up as a living lab and knowledge providers, students, and users, local citizens, solved the problem jointly. Although the methods of living labs are different from each other, they are introducing new research and education methods and utilizing participatory governance.
