Recently there has been a high request for support for teachers' professional development and quality control to meet the demand of educational policy to introduce teacher evaluation, master teacher status, incentives for teacher competency, etc. It has been suggested that reeducation and support for professional development would be more effective to beginning teachers with a high developmental potential than to experienced teachers with routinized instruction. Since 2005, KICE-TLC has conducted research on the development of teacher supporting programs such as teaching consultation and pedagogical content knowledge(PCK) in school subjects. In line with the current education policy and previous research by KICE, this research has been conducted to meet the need for novice teacher induction by developing consulting program focused on PCK. The goal of this research was to (1) explore the in-depth meaning of PCK in light of teaching consultation, (2) conduct a preliminary study on how to develop teaching consulting programs for secondary beginning teachers, (3) develop teaching consulting programs focused on pedagogical content knowledge(PCK), and (4) suggest implications for educational policy regarding pre-service and in-service teachers' continuing professional development and support.

This study investigates how librarians view library user privacy. To this end, a four-part survey was conducted: respondents' opinions about the privacy of library users, the degree to which library records violate the users' privacy, the role libraries and librarians fulfill to ensure user privacy protection, and librarians' need for privacy education. Results showed that librarians were very aware of privacy issues, but they perceived that library users' privacy awareness was not high. In particular, they had little knowledge of what library records or which library tasks might have the potential to violate users' privacy. In addition, awareness efforts of librarians to ensure user privacy was very low. On the other hand, the need for library user privacy educational programs was shown to be very high, and the willingness to participate was also relatively high.

The widespread pursuit for the thin physique may have detrimental impact on the wellbeing of the young generation, especially females. This study aimed to determine the effect of wanting very low body weight on dietary habits and psychological factors of female adolescents. Participants were 619 girls from 5 high schools in Kyeonggi, Korea. Information on dietary behaviors, psychological factors as well as current heights and weights and the desired weight for current height were obtained by questionnaire. Of total subjects, 38.1%, 35.5%, and 26.5% desired weights corresponding to normal (10~85 percentile), low (3~10 percentile) and very low BMI (< 3 percentile), respectively. The subjects who wanted to be very low weight had the average BMI of 18.57 kg/m2, which was significantly lower than $21.21kg/m^2$ of those who wanted to be normal weight (p < 0.001). The subjects who desired very low weight had significantly higher scores for depression symptoms (p < 0.05), while there were no differences in obsession to lose weight and obesity stress. Moreover, more subjects in this group had undesirable dietary habits such as eating fast foods more than weekly (p < 0.05). These findings suggest that the desire for extreme thinness may lead female adolescents to have not only unreasonably similar obesity stress and obsession to lose weight but also higher depression symptoms, along with undesirable dietary habits. The findings suggest the potential harm from excessive weight concerns of female adolescents; thus efforts to teach this group about healthy weights are urgently needed.

A novel protease gene from Bacillus gibsonii, aprBG, was cloned, expressed in B. subtilis, and characterized. High-level expression of aprBG was achieved in the recombinant strain when a junction was present between the promoter and the target gene. The purified recombinant enzyme exhibited similar N-terminal sequences and catalytic properties to the native enzyme, including high affinity and hydrolytic efficiency toward various substrates and a superior performance when exposed to various metal ions, surfactants, oxidants, and commercial detergents. AprBG was remarkably stable in 50% organic solvents and retained 100% activity and stability in 0-4 M NaCl, which is better than the characteristics of previously reported proteases. AprBG was most closely related to the high-alkaline proteases of the subtilisin family with a 57-68% identity. The secretion and maturation mechanism of AprBG was dependent on the enzyme activity, as analyzed by site-directed mutagenesis. Thus, when taken together, the results revealed that the halo-solvent-tolerant protease AprBG displays significant activity and stability under various extreme conditions, indicating its potential for use in many biotechnology applications.

EU's future frontier remains indefinite but it is directly linked to the principle of entry into the EU. EU has been defining that the 'european nation' sharing with a EU's value and norms can enter into the EU. If so, what is the criteria of EU? The criterion of 'european nation' will be a theoretical basis of an estimation of the EU's future frontier. However, the future frontier based on the geography, the culture and the intension of nation is only the potential frontier. It will be changed by the political decision makers' negotiation and power. EU's enlargement policy is one of means to retention of the international power in the situation that a few nations gradually dominate the world. Therefore the EU's frontier will be continually changed and created by the EU's political adventure.

Linux was developed by Linus Torvalds at University of Helsinkyi, Finland. Today Linux becomes to compete with windows operation of Microsoft. and is adopted worldwide on IBM products. The British government is viewing Linux as a desktop operating system. In Tunisia, Linux is under consideration as the governmental operating system. Even Sun Microsystems, the powerful supplier in workstation and sewer market, is working on developing ways in using Linux. is now getting further attentions on governmental level in several countries. The growing interests in adopting Linux in computer operating systems are not on a personal preference level any more. A number of companies and organizations, even some governmental administrations start to see its potential capabilities and are looking for ways for its applications. The necessity of teaching Linux in university is, therefore, imminent and should be discussed in course development without delay. The purpose of this paper is showing the things to be considered, problem analysis and some solution as grafting Linux in university education.

The research object is stepwise process of absorptive capacity is important factor to get the successful result of technology commercialization training program. We analyze the relationship between absorptive capacity and educational performance with empirical study to the students who attended the technology commercialization training program. Results show that potential absorptive capacity has positive effect on realized absorptive capacity. Realized absorptive capacity also has the positive effect on educational performance. We conclude the successful technology commercialization training program is based on the stepwise process of absorptive capacity. That means technology commercialization training program will set up based on not functional but stepwise process. Further more, technology commercialization training program must be practical, focusing, interdisciplinary, and repetitive courses.

Rock is a heterogeneous material, which introduces complexity in the analysis of rock slopes, since both the existing discontinuities within the rock mass and the intact rock contribute to the degradation of strength. Rock failure is often catastrophic due to the brittle nature of the material, involving the sliding along structural planes and the fracturing of rock bridge. This paper proposes an advanced discretization method of rock mass based on block theory. An in-house software, GeoSMA-3D, has been developed to generate the discrete fracture network (DFN) model, considering both measured and artificial joints. Measured joints are obtained from the photogrammetry analysis on the excavation face. Statistical tools then facilitate to derive artificial joints within the rock mass. Key blocks are searched to provide guidance on potential reinforcement measures. The discretized blocky system is subsequently implemented into a discontinuous deformation analysis (DDA) code. Strength reduction technique is employed to analyze the stability of the slope, where the factor of safety can be obtained once excessive deformation of slope profile is observed. The combined analysis approach also provides the failure mode, which can be used to guide the choice of strengthening strategy if needed. Finally, an illustrated example is presented for the analysis of a rock slope of 20 m height inclined at $60^{\circ}$ using combined GeoSMA-3D and DDA calculation.

Background: Depression is the most common psychological reactions in women with breast cancer. This study aimed at investigating the amount of depression and its role in predicting the quality of life of women suffering from breast cancer. Materials and Methods: The present descriptive study in volved a correlation method with 98 women living in Kermanshah-Iran with breast cancer. According to the access to the patients and the condition of conducting the research, they were chosen by available sampling. Life quality inventory (World Health Organization, 1989) and depression inventory (Beck et al., 2000) were used to gather the data. Moreover, to analyze the relationships among the variables correlation analysis with Pearson method, as well as multiple regression with the enter method and frequency analysis were applied. Results: The findings revealed that not only is depression high, but also there is a negative significant relationship between depression and the quality of life, with predictive potential. Conclusions: The finding of a relationship between depression and the quality of life points to the need for addressing psychological problems of the affected individuals more appropriately. It is suggested that we consider psychological and educational services for patients in treatment planning to make people aware of different psychological aspects of their disease and ways of struggling and overcoming the problems.

Background: There is a long standing interest in the identification of medicinal plants and derived natural products for developing cancer therapeutics. Here we investigated the antiproliferative properties of Melissa officinalis (MO) from Turkey on breast cancer. Methods: MO extracts were studied for cytotoxicity against breast cancer cell lines (MCF-7, MDA-MB-468 and MDA-MB-231). In vitro apoptosis studies were performed by annexin V staining and flow cytometry analyses. Immunohistochemistry for Ki-67 and caspase 7 in the tumoral tissue sections of DMBA-induced mammary tumors in rats was also performed, along with TUNEL assays to detect apoptotic cells. In vivo anticancer activity testing was carried out with reference to inhibition of growth of DMBA induced mammary tumors in rats. Results: MO showed cytotoxicity against three cancer cell lines, inducing increase in Annexin-positive cells. Expression of caspase-7 protein and TUNEL positive cells were much higher in rats treated by MO, compared with the untreated control group, while expression of Ki-67 was decreased. Furthermore, in vivo studies showed that mean tumor volume inhibition ratio in MO treated group was 40% compared with the untreated rats. Conclusion: These results indicated that MO extrcts have antitumoral potential against breast cancer.
