Single-person household is estimated to be about 26.5% of the total household in 2015, which counts as 5060000 in numbers. We opt to acknowledge the various requests of these single residents, and in order to raise their satisfaction, we investigated on how personal taste, psychological interest, and personality attribute affects the user's preference of space organization and furniture in one room housing. Using the qualified psychology program, Enneagram Personality Type Indicator, we surveyed young people under 30 years old (majority of single-person households), regarding space organization and furniture preference. With the help of a specialist, the survey was constructed with appropriate evaluation items (space organization in one room households, bed, sofa, furniture material, etc), and analyzed the relationship between the evaluated items and personality types. Results showed there is a relationship between personality types and spatial structure. First, preference of spatial structure differed for different personality types. Second, the shape and size of furniture was dependent more on the ease of usability and design rather than on the personality types. One thing to consider is that type 1 and 9 accounted for about 50% of the total surveys. This emphasizes that the preferred spatial structure of a dominant specific personality type should not be overlooked.

Colloidal semiconductor quantum dots (QDs), because of the novel optical and electrical properties that stem from their three-dimensional confinement, have attracted great interest for their potential applications in such fields as bio-imaging, display, and opto-electronics. However, many semiconductors that can be exploited for QD applications contain toxic elements. Herein, we synthesized non-toxic ZnTe/ZnSe (core/shell) type-II QDs by pyrolysis method. Because of the unique type-II character of these QDs, their emission can range over an extended wavelength regime, showing photoluminescence (PL) from 450 nm to 580 nm. By optimizing the ZnSe shell growth condition, resulting ZnTe/ZnSe type-II QDs shows PL quantum yield up to ~ 25% with 35 nm PL bandwidth. Using a simple two step cation exchange reaction, we also fabricated ZnTe/ZnSe type-II QDs with absorption extended over the whole visible region. The visible-light sensitized heavy metal free ZnTe/ZnSe type-II QDs can be relevant for opto-electronic applications such as displays, light emitting diodes, and bio-imaging probes.

The purposes of this study were to investigate the differences of post-purchase satisfaction, brand loyalty, and repurchase intention of SPA clothing brand according to lifestyles, and to disclose how lifestyles, post-purchase satisfaction, and brand loyalty influence the repurchase intention. The research method was a survey method using questionnaires. The subjects were 304 female college students residing in Seoul metropolitan area. The lifestyles were classified into six factors including pursuit of challenges, proactive interpersonal relationship, interest in sports, self-centeredness, interest in IT, and achievement orientation. Three female groups were derived by cluster analysis of the 6 lifestyle factors: active-activity type, passive-activity type, and achievement-pursuit type. Brand loyalty was classified into two factors including continuing loyalty and convenient loyalty. First, the active-activity group showed higher convenient loyalty than the other groups. The achievement-pursuit group showed higher post-purchase satisfaction than the other groups in appearance of clothing, while the passive-activity group showed lower satisfaction in every factor, in particular, its price satisfaction was very low. Second, senior students showed higher continuing loyalty than freshmen, sophomores, and juniors. Students with more clothing expenses showed higher continuing loyalty as well as convenient loyalty than those with less clothing expenses. Their price satisfaction with SPA clothing brand as well as repurchase intention was higher. Third, repurchase intention was influenced by brand loyalty the most, and the next in the order by satisfaction level with brand, satisfaction with price, satisfaction level with appearance, and proactive interpersonal relationship. The brand loyalty was influenced by satisfaction level with price the most, and the next by satisfaction level with appearance.

Damage detection in civil engineering structures using the change in dynamic system parameters has gained a lot of scientific interest during the last decade. By repeating a dynamic test on a structure after a certain time of use, the change in modal parameters can be used to quantify and qualify damages. To be able to use the modal parameters confidentially for damage evaluation, the effect of other parameters such as excitation type, ambient conditions,... should be considered. In this paper, the influence of excitation type on the dynamic system parameters of a highway prestressed concrete bridge is investigated. The bridge, B13, lies between the villages Vilvoorde and Melsbroek and crosses the highway E19 between Brussels and Antwerpen in Belgium. A drop weight and ambient vibration are used to excite the bridge and the response at selected points is recorded. A finite element model is constructed to support and verify the dynamic measurements. It is found that the difference between the natural frequencies measured using impact weight and ambient vibration is in general less than 1%.

Presence of small amount of old newsprints printed with waterbased flexographic inks leads to a significant loss brightness of the deinked pulp by flotation process. Recently there has been an increased interest in employing neutral deinking processes to solve the problems associated with waterbased flexo ink. A comparative experimental study was performed to evaluate the efficiency of neutral deinking and conventional alkaline deinking for ONP furnishes contaminated with flexo ink. It was shown that neutral deinking provides significant improvements in brightness, yield and freeness as compared with alkaline deinking. Flotation efficiency was different depending upon the type of surfactants used in neutral deinking. The result of this study showed that alcohol type surfactant is superior to fatty acid type surfactant in neutral deinking efficiency.

Square beam type piezoelectric vibrating gyro is developed for the measurement of angular velocity, which is compact, small in size and mass- producible. It features that three pieces of piezoelectric ceramics and bonded onto one face of equilateral square bar type gyro head. Two of them are used as sentuators which drive the gyro head and measure Coriolis force. The third piece is used for the feedback signal in order to resonate the gyro head and measure Coriolis force. The third piece is used for the feedback signal in order to resonate the gyro head with its fundamental natural frequency. Matching two fundamental natural frequencies in the gyro head with its driving frequency is found critical in the design of vibration gyro. Calibration results show that the vibrating gyro developed has the dynamic characteristics of first-order system within the frequency range of interest, which can be easily compensated by a lead compensator.

There is great interest in developing magnetoresistance(MR) sensor, using ferromagnetic, electrically non-magnetic conducting and antiferromagnetic films, especially for the use in weak magnetic fields. Here, we report single and Wheatstone-bridge type of MR sensors made in Si(001)/HiO(300$\AA$)/NiFe bilayers. Angular dependence of MR profiles was measured in Si(001)/NiO(300$\AA$)/NiFe(450$\AA$) films as a function of an angle between current and applied field direction, also, linearity was determined. AMR characteristics of single MR sensors was well explained with single domain model. Good linearity in 45$^{\circ}$Wheatstone-bridge type of MR sensors consisting of 4 single MR sensors made in Si(001)/NiO(300$\AA$)/NiFe(450$\AA$) was shown in the range of about $\pm$50 Oe.
