  • We study convergent influence on Job Satisfaction(JS) and its association with Self Efficacy(SE), Job Characteristics(JC) and Occupational Stress(OS) among Hospital Administrative Staff(HAS). The survey was administered to 221 staff from 11 general hospitals located in Jeonbuk area from Nov. 1st, 2016 to Jan. 31st, 2017. The structured self-administered questionaries were used. JS was positively correlated with SE and three sub-domains of JC, and it was negatively correlated with seven sub-domains of OS. With the analysis of covariance structure, OS was more influential on JS than SE and JC. The study found the higher SE and JC, and the lower OC tend to increase JS. The results indicate that the efforts, to increase SE and JC, and to decrease OS, are required to increase the JS of HAS. The results are expected to be useful for organization personnel management to increase the JS of HAS. In the following study, the analysis about convergent additional factors of influence on JS will be needed.

  • Streptomyces tendae JC412 secreted two forms of protease(ST -1 and ST -2) when grown in OSY medium (oatmeal 1.5%. soybean meal 2%. dried yeast 1 %) supplemented with glucose(0.5%) and KH2PO4(0.05%). Initial pH of the culture medium was adjusted to 10.0 with NaOH and incubated at $27^{\circ}C$ on a rotary shaking incubator (180rpm). High- molecular-weight protease ST-1 was heat labile. whereas low molecular protease ST-2(22.000 Da) was reported to be heat stable. (omitted)

  • PURPOSES : This investigational survey is to observe a proper spatial aggregation method for path travel time estimation using the hi-pass DSRC system. METHODS : The links which connect the nodes of section detectors location are used for path travel time estimation traditionally. It makes some problem such as increasing accumulation errors and processing times. In this background, the new links composition methods for spatial aggregation are considered by using some types of nodes as IC, JC, RSE combination. Path travel times estimated by new aggregation methods are compared with PBM travel times by MAE, MAPE and statistical hypothesis tests. RESULTS : The results of minimum sample size and missing rate for 5 minutes aggregation interval are satisfied except for JC link path travel time in Seoul TG~Kuemho JC. Thus, it was additionally observed for minimum sample size satisfaction. In 15, 30 minutes and 1 hour aggregation intervals, all conditions are satisfied by the minimum sample size criteria. For accuracy test and statistical hypothesis test, it has been proved that RSE, Conzone, IC, JC links have equivalent errors and statistical characteristics. CONCLUSIONS : There are some errors between the PBM and the LBM methods that come from dropping vehicles by rest areas. Consequently, this survey result means each of links compositions are available for the estimation of path travel time when PBM vehicles are missed.

  • JC Raulston Arboretum of the North Carolina State University houses 113 species of Korean native landscape woody plants. Styrax japonicus 'Emerald Pagoda'[formerly 'Sohuksan'] is native to Korea, China, and Japan. 'Emerald pagoda' is a special cultivar found by DR. J.C. Raulston during the United States National Arboretum plant collection expedition of the island of Sohuksan at the Western end of the Korea in 1985. Incredible, thick, glossy, large-leafed form of this beautiful white flowering tree found in Korea in 1985. It was probably the most outstanding ornamental plant to come from the expedition after his trip to Sohuksan and Chindo in the harsh perilous islands of the coast of Korea. He brought this one back in his suitcase. Viburnum awabuki 'Chindo' is and evergreen broadleaf shrub. It is for screening and as fire resistant trees in the southern region of Korea, because of its compact, leathery leaves. 'Chindo' was discovered on the island of Chindo by the U.S. National arboretum plant exploration team including J.C. Raulston during its 1985 Korean trip. Cuttings were taken from this plant, and liners were produced over subsequent years. These liners are now being evaluated for hardiness and fruit production throughout the Southeast of USA.

  • The effects of the particle size of precursor powder on the microstructure and Jc of Ag-sheathed Ri-2223 tapes were investigated. The calcined powder with overall composition of $Bi_{1-89}Pb_{0-41}Sr_{2-01}Ca_{2-23}Cu_{3-03}O_{y}$ was milled for various times using planetary ball mill. The transport property of the tapes were found to depend strongly on the particle size of the precursor powder Enhanced reactivity of the milled powder facilitated the formation of 2223 phase and resulted in an increase of Jc. Excessive milling, however, led to the amorphisation of the powder and degraded the electrical property of the tapes.

  • Melt spun YbBa2Cu3Agx(x=0, 5, 12, 16 and 53) precursor alloy ribbons were oxidized at 263-330$^{\circ}C$ and treated at 820$^{\circ}C$, 855$^{\circ}C$ and 885$^{\circ}C$ under 1.0 atm oxygen pressure. In the ribbons treated at 820$^{\circ}C$, 855$^{\circ}C$and 885$^{\circ}C$ 1-2-4 phase (YbBa2Cu4O8) and 1-2-3 phase (YbBa2Cu3O{{{{ OMICRON _7-$\delta$ }})were formed respectively. The shape of 1-2-4 phase was distorted or ellipsoid. The 2-4-7 and 1-2-3 phases tooked the shape of bar. All the ribbons showed zero critical current density Jc at 77K in zero magnetic field. By considering the shape and the highest critical temperature (among the three phases) of the 1-2-3 phase we tried to increase the critical current density of the ribbons treated at 885$^{\circ}C$ by press deformation. About tenribbons were stacked and coupled by press deformation and then treated at 885$^{\circ}C$ These 1-2-3 phase did not show any texture in any of the ribbons. However they exhibited weak texture in the multilayered specimens. Among the multilayered specimens YbBa2Cu3Ag16 exhibited a Jc of 180 A/cm2 Among the above ribbons YbBa2Cu3Ag16 ribbon has the optimum composition to produce textured superconducting oxide with improved Jc by press deformation. Onset critical temperatures Ton of the multilayered YbBa2Cu3Agx(x=5, 12, 16 and 53) were measured as 88-90 K.

  • In this paper, we propose a deep learning-based person re-identification method using a three-dimensional RGB-Depth Xtion2 camera considering joint coordinates and dynamic features(velocity, acceleration). The main idea of the proposed identification methodology is to easily extract gait data such as joint coordinates, dynamic features with an RGB-D camera and automatically identify gait patterns through a self-designed one-dimensional convolutional neural network classifier(1D-ConvNet). The accuracy was measured based on the F1 Score, and the influence was measured by comparing the accuracy with the classifier model (JC) that did not consider dynamic characteristics. As a result, our proposed classifier model in the case of considering the dynamic characteristics(JCSpeed) showed about 8% higher F1-Score than JC.
