This study set up a study model through a previous study and aims to determine the control effect by organizational support in the effect relationship between consulting performance which is an independent variable and organizational performance which is a dependent variable. To do that, the hypothesis was verified by using statistical programs such as SPSS 20.0 and AMOS 20.0 which can be statistically useful with 511 copies except for the copies which cannot be utilized, over 4 weeks from February $25^{th}$ to March $24^{th}$, 2015, focusing companies located in Seoul, Gyeonggi, Incheon. The hypothesis testing result of the study model set by this study shows that firstly, this study has contributed to establishing an additional theory in the research between consulting performance and organizational performance while it has not been enough for consulting performance and organizational performance in previous studies. Second, although the moderating variable of organizational support in the effect relationship between consulting performance and organizational performance didn't show a partial positive (+) role in the hypothesis testing, more detailed analysis in the survey process and the variety on questionnaire configuration were provided in the variable selection. Third, as consulting performance shows a positive effect on organizational performance, a higher consulting performance gives a direct impact on organizational performance so that a realistic action plan on internalizing and enhancing consulting execution result into organizational performance is aggressively required.

This study empirically analyzed the factors affecting the intention to utilize manufacturing AI in SM-sized manufacturers by applying the TOE framework. Independent variables that are expected to influence were applied, focusing on TOE factors and managerial characteristics that reflect the characteristics of SME manufacturers. In addition, the mediating effect of technology trust and the moderating effect of factory location were analyzed. The results are as follows. First, the relationship between the independent variables and the dependent variable was tested, and the direct effects of the independent variables(complexity, organizational innovation, IT ability, competitive pressure, partner support, and managerial innovation) on the dependent variable were all statistically significant, except for compatibility. Second, the mediation effect of technology trustness was verified to have a full mediation effect between compatibility and utilization intention, and a partial mediation effect between managerial innovation and utilization intention. Third, among the seven independent variables, the moderating effect of factory location(metropolitan and non-metro) between the three independent variables of IT ability, competitive pressure, and partner support and the utilization intention was found to be significant. To increase the intention to utilize manufacturing AI for SM-sized manufacturers, it is recommended that more diverse and broader studies are needed, not only the factors identified in this study, but also the understanding and awareness of manufacturing AI.

Methods : We investigated 28 cases of patients with thoracolumbar compression fracture. We divided patients into two groups : We treated one group with complex oriental medical treatment focusing on Bee Venom Acupuncture therapy, and did the other group with complex oriental medical treatment focusing on acupuncture therapy. To investigate the effectiveness of treatment applied for two groups, we used Visual Analog Scale(VAS) and Oswestry Low-back Pain Disability Index(ODI). We compared the VAS score and ODI score of two groups statistically. Results : 1. Female is prominent in distribution of sex, the average age bracket is 70's, and the largest group was Faccidental fall in the distribution of cause. 2. In regard to level of injury, T12 was found to be most prominent, followed in turn by L1, L2. In regard to grade of clinical symptoms, Grade III was most prominent, followed by Grade IV, Grade II. 3. As a result of evaluation by using VAS score and ODI score, treatment score at final was significantly different from that at the baseline in each group. 4. After treatment, Bee Venom acupuncture therapy group showed significant difference on VAS score and ODI score compared with acupuncture therapy group. Conclusions : Bee Venom acupuncture therapy can be available for relieving symptoms related with thoracolumbar compression fracture.

The teaching-learning method utilizing Web makes it possible for the students take the initiative in any field and offers the teaching strategy, methodology and teaching-learning materials suitable for students' ability and standard. The purpose of this study is to investigate the characteristics of WBI in mathematics class for the effective teaching and learning focusing on the unit 'Function' in the 1st grade of middle school and verify its effectiveness by developing the WBI programs which can progress learning achievement and applying them to math class. Two hypotheses were established for this study. Hypothesis 1 : There will be meaningful difference between the group that studies under WBI and the one that doesn't, Hypothesis 2 : There will be meaningful difference in the attitude and interest toward learning between the group that studies under WBI and the one that doesn't. In order to find out the result, I have made a comparative analysis through t-verification on the object of two classes of the 1st grade in P middle school that I have been working for. The result shows that the class utilizing WBI is more effective than the traditional lecture-oriented class since there is a meaningful difference between the control group and experimental one and also that the class based on WEB has a great influence on students' interest and positive attitude toward math class.

The prosodic characteristics of Korean particles in read speech were examined in this paper based on K-ToBI labeling system in order to see whether they are prosodically weak form like functions words in English. Acoustic measurements and statistical analysis were done focusing on the distribution of particles over a variety of prosodic positions, prosodic positional effects on the phonetic realization of particles, and acoustic strength of particles compared to those of their surrounding syllables. The panicles were distributed rather equally over all 4 prosodic positions with the highest frequency at IP-medial/AP-final position and the lowest at IP-medial/AP-medial position except that topic marker 'Un/nUn' showed preference for IP-final/AP-final position. There was a significant prosodic positional effect on the duration and F0 of the particles. Duration was the longest at IP-final/AP-final position and interestingly, at IP-medial/AP-medial position while F0 was the highest at IP-final/AP-medial Position as expected. The comparison of the acoustic properties of the particles with those of neighbor syllables showed that duration was generally significantly longer and energy also showed larger values, if not significant, in particles suggesting that the particles in Korean are not prosodically weaker like function words in English.

Prior studies on knowledge sharing have concentrated primarily on either organizational or individual characteristics. However, by focusing on the interaction between members in On-line communities of practice (CoPs), we seek to identify and analyze factors that affect knowledge sharing by members in CoPs. Therefore, we examine if the independent variables such as interactivity, followership, and trust have positive impacts on the dependent variables such as commitment to CoPs and intention to share knowledge. In addition, this study also investigates the relationship between commitment to CoP and intention to share knowledge. The empirical results show that interactivity has a positive impact on commitment, but an insignificant impact on intention to share knowledge. Besides, trust between members is significantly associated with intention to share knowledge, whereas it does not have a significant effect on commitment. Moreover, followership is significantly related to both commitment and intention to share knowledge. These empirical findings show that the relationship between members in CoPs play a significant, positive role in intention to share knowledge. In conclusion, this research contributes to shedding a light into both interactions between members in and commitment to CoPs that are critical to facilitate knowledge sharing.

The purpose of this study was to analyze the effects of children's self-esteem on their school adjustment, focusing on the mediation of peer attachment. A total of 2,200 3rd grade children from the third Korea Child-Adolescent Panel Survey participated in this study. The instruments used in this study were the Self-esteem Scale, Peer Attachment Scale, and School Adjustment Scale. The collected data were analyzed by using a Student's t -test, Pearson's partial correlation, simple regression, and hierarchical multiple regression with SPSS ver. 16.0 software. The main results of this study are as follows: first, the boys had higher self-esteem, peer attachment, and school adjustment scores than the girls. Second, there was a significant positive correlation between children's self-esteem and peer attachment as well as a significant positive correlation between children's self-esteem and school adjustment. Further, there was a significant positive correlation between children's peer attachment and school adjustment. Finally, children's self-esteem exerted positive effects on their peer attachment, and children's peer attachment had a positive influence on their school adjustment. The effect of children's self-esteem on their school adjustment was partially mediated by their peer attachment. These findings provide preliminary evidence that the relationships between children's self-esteem and school adjustment may be mediated by their peer attachment.

The phased array transducer has two distinct advantages. One is rapid scanning comparing with the conventional mechanical or manual scanning system. Therefore, output image is represented in real-time. The other is the dynamic focusing and the dynamic steering of ultrasonic beam. Only the delay times that are controlled electrically are used to focus and to steer beam without any lenses or wedges. In this study, the profile of the ultrasonic beam for the phased array transducer has been simulated in the Huygens principle with varying the inter-element spacing of the linear phased array transducer. From the result of this study, it was found that the ultrasonic beam spread wider as the inter-element spacing was decreased. However, the focusing effect was improved, even when the number of the element was not big. In addition, there was grating lobes that are constructed when the inter-element spacing is more than half wavelength. However, this grating lobe has lower amplitude than the main lobe.
