Globalization in the 21st century and development in the field of IT have caused rapid change in the practical site of fashion industry. Therefore, as colleges aim to produce professional technicians and experts in the applicable fields, they are strengthening professionalism and practicality more than ever before that can respond to the practical situation. In addition, owing to the reduction of population of academic students, colleges would search for specialty and structural innovation with the serious desire to establish new structural system to produce talented persons. Purpose of this study is to strengthen competition of colleges voluntarily, specialize themselves and maximize mutual benefit through cooperative relation with industrial businesses. Thus, this study would compare, analyze and investigate the curriculums of fashion designs in colleges for the plan of curriculum applicable for the industrial changes and corresponding business demand. Considering the result of questionnaires of industrial businesses, most of them would prefer the curriculum for 3 years to that for 2 years. Nowadays industrial businesses will require computerization ability much more than ever before besides the professional knowledge and technology in the field of fashion and it is also showed that education of personality in colleges would be considered to be important for the performance of the vocational duty. Especially, specialty and progressive participation in the curriculum would be strengthened during the education process of colleges. This study will be used for the establishment of specialty of colleges and development of curriculum of them.

Signal individual reconnaissance and identification is an extremely important research topic in non-cooperative domains such as electronic countermeasures and intelligence reconnaissance. Facing the characteristics of the complexity and changeability of current communication environment, how to realize radiation source signal individual identification under the low SNR conditions is an emphasis of research. A novel emitter individual identification method combined bi-spectrum analysis with wavelet feature is presented in this paper. It makes a feature fusion of bi-spectrum slice characteristics and energy variance characteristics of the secondary wavelet transform coefficient to identify MFSK signals under the low SNR (signal-to-noise ratios) environment. Theoretical analyses and computer simulation results show that the proposed algorithm has good recognition performance with the ability to suppress noise and interference, and reaches the recognition rate of more than 90% when the SNR is -6dB.

A comparative study on cadmium(II) complexation with three well characterized humic acids (SHA: soil humic acid from the Okchun Metamorphic Belt; AqHA: aquatic humic acid from Gorleben underground aquifer, Germany; CoHA: commercially available humic acid from the Aldrich Co.) was carried out in 0.1 M $NaClO_4$ at different solution pH(5.0, 5.5, and 6.0) using the ultrafiltration technique. The maximum binding ability (MBA) of the humic acids for cadmium(II) was observed to vary with their origins and solution pH. The results suggest that 1 : 1 complex predominates within the experimental range, and the conditional stability constants were calculated based on the assumption of cooperative binding, yielding log K values that were quite similar (CoHA: 4.17${\pm}$0.08; AqHA: 4.14${\pm}$0.07; SHA: $4.06{\pm} 0.12\;l\;mol^{-1}$ at pH 6.0) irrespective of humic acid origins or pH. By contrast a nonlinear Schatchard plot was obtained, using the cadmium(II) ion selective electrode speciation analysis method, which indicated that humic acid may have two or more classes of binding sites, with $log\;K_1\;and\;log\;K_2$ of 4.73${\pm}$ 0.08 and $3.31{\pm}0.14\;l\;mol^{-1}$ respectively.

Drug-induced gingival overgrowth is an abnormal increase of gingival tissues caused as a side effect of systemic medication. This report presents a severe case of valproate-induced gingival overgrowth combined with ulcerative and hemorrhagic lesions in a patient with Lennox-Gastaut syndrome. Considering the patient's limited cooperative ability, gingivectomy and excisional biopsy under general anesthesia were performed. The lesions were successfully treated without recurrence. When gingival enlargement does not subside with nonsurgical treatments, surgical procedure and excisional biopsy are to be performed. Postoperative management of oral hygiene is critical to prevent recurrence.

In the 21st century, university education is changing from an objective knowledge and information to critical thinking and problem-solving ability. Moreover, university education should change rapidly towards a learner-centered educational environment because it has an educational goal to have college students experience authentic tasks they will be in charge of after graduation, and improves self-directed learning ability and cooperative learning ability. PBL is a pedagogical strategy for posing significant, contextualized, real world situations, and providing resources, guidance, and instruction to learners as they develop content knowledge and problem-solving skills. In problem based learning, the students collaborate to study the issues of a problem as they strive to create viable solution. For these advantages of PBL, the application of PBL in school has been enlarged. On the other hand, the application of PBL in engineering education has not been enlarged. To improve these instruction methods, the development or applications of new instructional methods will be needed. This study examined the PBL instructional design of a creative engineering design subject, which aims to foster talent. The PBL model developed in this study consists of Analysis, Design, Development, Implementation, and Evaluation. A plan of creative engineering design subject was developed based on PBL, and focused on the process of PBL. To determine the effects of this model, studies applying this instructional design to many lecturers should be implemented.
