The majority of previous research on start-ups consist of research on leading variables that affect the entrepreneurial intention related to start-ups established by young people, college students or senior citizens, and the influencing relationships regarding start-ups in the sense of their form such as independent start-ups, franchising start-ups, small business start-ups, etc. It is difficult to find research on entrepreneurial intention targeting office workers. This study investigates the question of how office workers' entrepreneurial mindset affects their entrepreneurial intentions, focusing on mediating role of social capital and moderating role of state-action orientation. We use survey data to empirically test the relationships between the variables in question. This study finds the presence of the positive effect of entrepreneurial mindset on social capital that significantly promotes entrepreneurial intention, demonstrating mediating role of social capital. We understand the existence of moderator, action state, showing that entrepreneurial intention is affected by interaction of entrepreneurial mindset and action state, not entrepreneurial mindset alone. We propose some policy implications based on the results of this study, and lists the limitations of the study.

The generalized 23 constants of the Benedict-Webb-Rubin-Starling (BWRS) equation of state were modified to achieve accurate predictions of thermo-physical properties for polar halocarbons. Multiproperty analysis was employed to obtain an optimum set of 23 constants for individual halocarbons. The overall average absolute deviations of predicted properties for those halocarbons using the 23 constants optimized for each halocarbon with use of either an acentric factor or orientation parameters are 0.41% for density, 0.33 Kcal/kg for enthalpy and 0.39% for vapor pressure. These results show a remarkable improvement in predicting properties over the ones obtained by use of the generalized constants for all the ten halocarbons tested here.

In induction machine drive without a speed sensor, the estimation of the motor flux and speed often becomes deteriorated at low speeds with low back EMF. Our analysis shows that, in addition to the state resistance variation, the estimated value of field orientation angle is often corrupted by accumulative errors from the integration of voltage variables at motor terminals that have low signal/noise ratio at low frequencies. A repetitive loop path of integration in the feedback can amplify this type of error, thus speeding up the degradation process. The control system runs into information starvation due to the loss of correct field orientation. The machine's spiral vectors are controlled only in a reduced dimension in this situation. A novel control scheme is developed to improve the control performance of motor's current, torque and speed at low frequencies. The scheme gains a full-dimensional vector control and is less sensitive to the combined effect of the error sources at the low frequencies. Experimental tests demonstrate promising performances are achievable even below 0.5 Hz.

NdAl3(BO3)4 have been developed for miniature solid state laser material. Single crystals of NdAl3(BO3)4 were grown by TSSG technique using BaB4O7 flux. The effects of growth conditions such as cooling rate, seed orientation and rotation speed on crystal quality and the morphology were studied. At the cooling rate of 2.4$^{\circ}C$/day and the crystal rotation speed of 30~40rpm with the seed orientation in <201> or <100> directions, transparent and light violet colored crystals in size of 10$\times$15$\times$20㎣ with well developed {010}, {111}, {111}, {021}, {001}, {102}, {112}, {021} faces were obtained. By X-ray diffraction analysis, the space group was determined as C2/c, and the X-ray powder data was obtained.

Theoretical model for membrane transport of large polye!ectroiyte is presented. When the electric field is applied, the molecular conformation quickly orients in the field direction showing overshooting orientation. the predicted dependence of overshoot time and orientation upon field intensity and molecular size aids to understand the dynamic motion of molecules in membrane transport. The dynamics of the overshoot is associated with self-trapping conformations of molecule. The understanding of these effects supports evidences for the electrophoretic filtration of polydectrolyte in the polymeric membrane. This paper shows one example for molecular study in the theoretical review paper of membrane transport.

This paper argues that the basic modes of spatial cognition can be best identified in terms of argument/participant location, and shows that natural language uses‘simple’types of semantic denotations to encode spatial cognition, and further notes that spatial expressions should be interpreted not as locating an event/state as a whole but as locating arguments/participants of the event. The ways of locating events/states are identified in terms of argument orientation(AO), Which indicates semantic patterns of linkiarticipant location. and shows that natural langrage uses ng locatives to specific arguments. Four patterns of argument orientation described here reveal substantial modes of spatial cognition. and the AO patterns are mostly determined by the semantic classes of English verbs combining with locative expressions, i.e., by the event type of the predicate. As for the denotational constraint of locatives, the paper concludes that semantic denotations of locative PPs are restricted to the intersecting functions mapping relations to relations.

The structure and mechanical properties of TiN and TiCN thin films deposited on STD61 steel substrates by the RF-sputtering methods has been studied by using XPS, XRD, micro-hardness tester, scratch tester, and wear-resistance tester. XPS results showed that the TiCN thin film formed with chemical bonding state. The TiN thin films grew with (111) orientation having the lowest strain energy by compressive stress, whereas the TiCN thin films grew with both (111) and (200) orientation, but (200) orientation having the lowest surface energy becomes dominant as carbon contents increase. The pre-etching treatment of substrate did not affect on the preferred orientation of thin films, but it played an important role in improving mechanical properties of thin films such as the hardness, adhesion and wear- resistance. Especially, the TiCN thin films showed the superior wear resistances due to high hardness and low friction coefficient compared with TiN thin films.

This study assessed behavioral characteristics of 73 normal neonates in Daegu area using the NBAS. Being one of few studies on this topic, the study is to document and to accumulate data on the neonatal behaviors of Korean babies. Overall scores were at moderate levels in 6 behavioral clusters including Habituation, Social Interactive, Motor System, State Organization, and State Regulation. Autonomic Stability showed relative stableness. Scores of Orientation were higher in neonates of working mothers and rural mothers. Neonates of mothers with no abortion history have higher scores in Motor System and State Organization. Score of State Organization was higher in neonates of mothers with no habitual use of amenity during their pregnancy. Scores of Habituation and State Organization, as well as scores of Motor System with State Organization, State Regulation and Autonomic Stability were positively correlated. Scores of Habituation and State Organization indicate that babies are agreeable and even tameable that is advantageous for attachment to caregiver.

Effects of gravitational orientation on gas tungsten arc welding (GTAW) for 304 stainless steel were studied to determine the critical factors for weld pool formation, such as weld surface deformation and weld pool shape. This study was accomplished through an analytical study of weld pool stability as a function of primary welding parameters (arc current and arc holding time), material properties (surface tension and density), and melting efficiency (cross-sectional area). The stability of weld pool shape and weld surface deformation was confirmed experimentally by changing the welding position. The arc current and translational velocity were the major factors in determining the weld pool stability as a function of the gravitational orientation. A 200A spot GTAW showed a significant variation of the weld pool formation as the arc held longer than 3 seconds, however the weld pool shape and surface morphology for a 165A spot GTAW were 'stable', i.e., constant regardless of the gravitational orientation. The cross-sectional area of the weld (CSA) was one of the critical factors in determining the weld pool stability. The measured CSA ($13.5mm^2$) for the 200A spot GTAW showed a good agreement with the calculated CSA ($14.9mm^2$).
