A practice on learn-by-doing career education programs has been operated in Faculty of Engineering in Niigata University from 2006. The purpose of the activity is reduction of early unemployment which is due to the gaps between the situations which university students would expect in their job hunting processes and those of their practical work places after getting jobs. We developed a novel internship program to let the students notice the practical situations of engineers outside the university. A major part of the program is composed of two different kinds of internships and what we call a career design workshop. The characteristic programs are called "Market Internship" and "Technology Internship". In the activities, they are organically connected with each other. In the paper we refer to one of the unique internship programs "Technology Internship", which is characterized as a longer-term practice than usual. In the course of one-month internship practices, the students obtained deeper understandings and closer relationship to the practical work places of the companies than usual internships which last less than two weeks. The students estimated these unique experiences effective for their job hunting in near future.

Effect of energy deposition on TiO2 nanosized powder synthesized by pulsed wire discharge
Yoshinori Tokoi,Tsuneo Suzuki,Tadachika Nakayama,Hisayuki Suematsu,Futao Kaneko,Koichi Niihara 한국물리학회 2009 Current Applied Physics Vol.9 No.3
Titanium dioxide (TiO2) nanosized powder was synthesized by pulsed wire discharge (PWD) using Ti wire in O2 gas. The pressure of O2 gas (P) and relative energy (K), which is defined as the ratio of the charged energy of the capacitor to the vaporization energy in the wire, were varied from 10 to 100 kPa and 4.3– 51.9, respectively. The density of the plasma/vapor (Dexp), determined by the maximum volume, was decreased with decreasing P and increasing K as observed by high-speed photography during PWD. Xray diffraction analysis confirmed that the rutile content (CR) was increased from 7 to 84 vol% with decreasing Dexp. The median diameter (D50), determined from scanning electron microscopy, was decreased from 36.5 to 10 nm with decreasing Dexp. Therefore, an increase in CR and decrease in D50 both accompany the decrease in Dexp. Titanium dioxide (TiO2) nanosized powder was synthesized by pulsed wire discharge (PWD) using Ti wire in O2 gas.

Organic light emitting diodes (OLEDs) with nanostructured ultrathin layers inserted at the interface between electron- and hole-transport layers were investigated. The fundamental structure of the OLEDs fabricated by a vacuum evaporation method wasindium-tin-oxide (ITO) anode/copper phthalocyanine (CuPc)/N,N0-diphenyl-N,N0-bis(3-methylphenyl)-1,10-diphenyl-4,40-diamine(TPD)/8-hydroxyquinoline aluminum (Alq3)/LiF/Al cathode. Fullerene (C60) and rhodamine B (RhB) molecules were used as thenanosutructured ultrathin layers inserted at the interface between the Alq3 and TPD layers. The electroluminescent (EL) propertieshave been measured for the OLEDs with C60 and RhB ultrathin layers and the dependences on the thickness and the position of theinserted layers were examined. For the OLEDs with the C60 ultrathin layer, the improvements of the drive voltage and EL eciencywere observed. The OLED with the inserted C60 ultrathin lm of a monolayer thickness showed the highest eciency, which wastwice as large as that without C60 layer. On the contrary, the improvements were not observed for the OLEDs with the RhB ul-trathin layer..
Luminescence and photoelectric properties of thiophene dendrimer spin-coated films
Kazunari Shinbo,Yoshifumi Ikeda,Chuanjun Xia,Keizo Kato,Futao Kaneko,Rigoberto C. Advincula 한국물리학회 2005 Current Applied Physics Vol.5 No.4
Thiophene dendrimer spin-coated lms were fabricated and the optical and photoelectric properties were investigated.Absorption edge and peak of photoluminescence (PL) spectra for the lm were observed at around 550 and 618 nm, respectively.The excitation spectrum almost corresponded with optical absorption. From the voltage vs. current properties, the Schottkyconductions were estimated in the indium tin oxide (ITO)/dendrimer/Al device. Photoelectric properties were also observed and theaction spectra of the photocurrent in the device also corresponded with the absorption spectrum..
