Over the last several decades, the topic of the source selection and evaluation has gained a great attention in the information systems community as an effective tool to acquire information systems in an organization. The source selection and evaluation process is a multiple-criteria decision-making problem associated with several evaluation issues. In this case study, evaluation issues include management, technologies, logistics, and cost. This case study was conducted to compare a new source selection and evaluation process by using the analytic hierarchy process with the traditional approach. This study provides useful insight about how to apply the analytic hierarchy process technique to the traditional approach.

The purpose of this study is as well as Body decoration is a means to identify self-expression from the original nature of an individual freedom and originality, so there remains a race has not a cloth on, but there is no race does not pierce, it has been done with the beginning of a mankind. Subjects for this study were 202 persons, who experienced body piercing with twenties as the central figure. Statistical analysis was done by using SPSS 10.0 version and included AVOVA, Cronbach ${\alpha}$ realbility, Multiple Regression Analysis, Duncan's multiple range test, and Cross tabulation analysis. The result are as follow, The difference of self-conception classified by body piercer's sex distinction did not show significantly. Of the body piercer's feeling of depression to a sex role, neuter gender's feeling of depression showed highly in case of the physical self and the moral self and in case of the social self neuter's feeling and feminine gender's feeling to a sex role showed high. For the reason why he/she did body piercing, neuter gender's feeling showed high in case of influenced by the fashion and masculine gender's and feminine gender's feeling showed high in case of influenced by the curiosity. The body decoration classified by self-conception of body piercer did not show a significant difference.

In industrial multivariable plants, it is often the case that all of plant outputs are measured not simultaneously, but seriallu. While Reference 1 proposed a special type of observer (referred to as "serial-sampling" type obserrversL. which was provento be very effective in this situation, it alsopointed out that the observer may have some minor problems in case of practical applications. In this paper, it isshown that these kind of problems can be resolved by proving the existence of the solution of the simultaneous equations (35) of Reference 1.

This is a multiple-case study of how preservice secondary mathematics teachers teach a particular mathematics using a technological tool. In a performance interview, the preservice teachers demonstrated how they would teach a specific mathematical topic using Geometer's Sketchpad. The results of this study showed that the preservice teachers designed diverse types of lesson plans and implemented different pedagogical and technological techniques in their teaching demonstrations. The findings suggest that preservice teachers' pedagogical content knowledge is an important factor in the integration of technology into their mathematics teaching. Thus, mathematics teacher educators should help preservice teachers gain a robust pedagogical content knowledge in order to effectively teach mathematics with technological tools.

PURPOSES : This study aims to improve complex modeling of multivariable, nonlinear, and overdispersion data with an artificial neural network that has been a problem in the civil and transport sectors. METHODS: Deep learning, which is a technique employing artificial neural networks, was applied for developing a large bus fuel consumption model as a case study. Estimation characteristics and accuracy were compared with the results of conventional multiple regression modeling. RESULTS : The deep learning model remarkably improved estimation accuracy of regression modeling, from R-sq. 18.76% to 72.22%. In addition, it was very flexible in reflecting large variance and complex relationships between dependent and independent variables. CONCLUSIONS : Deep learning could be a new alternative that solves general problems inherent in conventional statistical methods and it is highly promising in planning and optimizing issues in the civil and transport sectors. Extended applications to other fields, such as pavement management, structure safety, operation of intelligent transport systems, and traffic noise estimation are highly recommended.

This study tests e-business performance difference of the inter group by strategy type through the cluster analysis, after confirming the linear relationship between the e-business strategy type and its performance. According to the result of the study the effect on the e-business performance reveals to differ by the e-business strategy type. That is to say, while the firm's information system performance, e-business realization and the inter group competition dominance are affected positively by the e-process strategy, web application strategy and customer attracting strategy. This confirms that the information system performance, the realization performance and the competition dominance are affected by e - business strategy type. The key factor leading to the success of e-business is the commitment of e-process strategy and web application strategy. For the case of the customer attracting strategy the result shows the importance of the strategy. In the cluster group analysis, the additional analysis, the effect is seen to be more powerful in the firm's information system performance, e - business realization and securing the competition advantage for the case of the multiple strategy than that of single one. Accordingly, the firm needs to adopt the multiple strategy suited for the characteristic of the firm rather than the single strategy.

The radiographic findings of soft tissue calcification in the oral and maxillofacial area was analysed using panoramic, skull P-A and intraoral radiographs in 250 patients. The obtained results were as follows ; 1. Salivary stone had the highest rate of occurrence at 46％(116 cases), followed by lymph node calcification(97 cases), phleholith(21 cases), multiple miliary osteoma(15 cases), antrolith(l case), vessel calcification(l case) and cysticercosis(1 case). 2. The prevalence of salivary stone was slightly higher in females, on the right side and in the middle-aged group and was especially higher in the submandibular gland(83％). The majority of them were round-shaped, homogeneously radiopaque and associated with sialodochitis. 3. The prevalence of lymph node calcification was higher in the female and old-aged group. Irregular shape and radiopaque bodies were seen in the cervical area, bilaterally. 4. The prevalence of phlebolith was slightly higher in the male, and the third decade group. The radiopaque bodies were 4-8 mm in diameter and had laminated appearance. 5. The prevalence of multiple miliary osteoma was higher in old-aged females. The numerous doughnut-shaped radiopaque bodies, sized 2-4 mm in diameter, were seen bilaterally in the cheek and were usually associated with the edentulous ridge.
