This study tried to develop an test tool of social workers' ethical sensitivity(SWEST) on base of realization about the importance of ethical sensitivity of social worker who are required more ethicalities than the other professionals. Nevertheless, there has been no tool that can measure ethical sensitivity of social workers in our country up to now. Through analysis of existing ethical sensitivity tests in other professions, a paper and pencil method about unstructured question with cases including ethical issues and structured scoring system was chosen as an appropriate method for the SWEST. This study progressed in order : 1st collecting cases, 2nd composing cases, 3rd consulting cases, 4th pilot study, 5th making scoring standards, 6th determining case examples and scoring standards. With the result, the tool consists of 3 case examples with ethical issues : 1) self-determination and confidentiality, 2) equality and double relationship, 3) informed consent and conflict interest. And ethical sensitivities of social work major students and social workers were measured with the SWEST, to see practical utility of this test. The agreement degrees between two independent raters were above 90%. And respondent's ethical sensitivity displayed the most definite difference according to taking or not taking a course 'Social work values and ethics'. Through these results, it can be drawn that the SWEST is reliable and valid to test relevant differences in Korean social workers' ethical sensitivity. The SWEST is expected to activate studying, educating, and practicing ethics in social work.

Background: Categorizing breast tumors based on the ER, PR and HER/Neu 2 receptor status is necessary in order to predict outcome and assist in management of breast cancer. Herfe we assessed this question in South Indian patients. Materials and Methods: A total of 619 formalin fixed paraffin embedded breast tumor tissues were collected from pathology archives after receipt of ethical clearance. With the help of primary and secondary conjugated antibodies, expression status of ER, PR and HER2/neu was determined. All the experimental data were assessed for correlations with histopathological features of tumors and clinical presentation of the subjects. Results: In the present study, the ages ranged from 20-87 years with a mean of $50.0{\pm}12.q$ years, and majority of the tumors (84%) were of infiltrating duct cell carcinoma type. Assessment of ER, PR and Her-2/neu expression showed that 46% were triple negative. Interestingly, an inverse relation between ER, PR and HER-2/neu was apparent in 41.2% (p<0.0001) of the tumors, of which 24.5% (p<0.0001) were ER and PR co-negative but HER-2 positive. Conclusions: ER and PR positive tumors are less common (i.e<30%) compared to HER-2/neu positive tumors (i.e>50%) in Indian breast cancer patients, underlining the need for effective diagnostic screening and specific therapeutic managements in order to improve the survival rate of patients in low resource countries such as India.

In environmental impact assessments for large urban development projects, the Korean government requires analysis of stormwater runoff before, during and after the projects. Though hydrological models are widely used to analyze and prepare for surface runoff during storm events, accuracy of the predicted results have been in question due to limited amount of field data for model calibrations. Intensive field measurements have been made for storm events between July 2015 and July 2016 at a sub-basin of the Gwanpyung-cheon, Daejeon, Republic of Korea using an automatic monitoring system and also additional manual measurements. Continuous precipitation and surface runoff data used for utilization of SWMM model to predict surface runoff during storm events with improved accuracy. The optimal values for Manning's roughness coefficient and values for depression storage were estimated for pervious and impervious surfaces using three representative infiltration methods; the Curve Number Methods, the Horton's Method and the Green-Ampt Methods. The results of the research is expected to be used more efficiently for urban development projects in Korea.

In this study, we are interested in the teachers' MCK about '$N{\div}0$' and MPCK in relation to the proper ways to teach it. Even though '$N{\div}0$' is not on the current curriculum and textbooks of elementary school mathematics, a few students sometimes ask a question about it because the division of the form '$a{\div}b$' is dealt in whole number including 0. Teacher's obvious understanding and appropriate guidance based on students' levels can avoid students' error and have positive effects on their subsequent learning. Therefore, we developed an interview form to investigate teachers' MCK about '$N{\div}0$' and MPCK of the proper ways to teach it and carried out individual interviews with 30 elementary school teachers. The results of the analysis of these interviews reveal that some teachers do not have proper MCK about '$N{\div}0$' and many of them have no idea on how to teach their students who are asking about '$N{\div}0$'. Based on our discussion of the results, we suggest some didactical implications.

The purpose of the research is that how awareness of importance of personal medical data, laws regarding personal medical data and perception gap regarding information of medical data system may affect usage of hospital convenience between a regular patient who has experienced hospital service and medical professionals. Preceding research analysis was conducted previous on establishing research model; 150 questionnaires to a regular patient and 150 questionnaires for a medical professional, total of 300 questionnaires were gathered for conducting a question investigation. First of all, the research concluded that there are a regular perception differences between a regular patient and medical professional. Moreover, there are perception differences among the different gender, age, and area of residence. Furthermore, medical professionals tend to consider that convenience of hospital usage will be increased if user strengthens recognition of security of personal medical data. Results of hypothesis stress that higher awareness of exposure of personal medical data and medical information system affect decision making convenience for a better usage of hospital. On the other side, awareness of laws related with personal medical information security does not affect decision making convenience of hospital usage and transaction. The results of the research analyzes with proof that strengthening awareness of personal medical data security positively increase convenience of decision making and transactions in selection of provided medical service.

The goal of this study is to compare entrepreneurial orientation of both countries' students and to compare the effect of individualism on developing entrepreneurial orientation of both countries. In order to achieve this goal, this study will conduct two analysis. Firstly, the comparative study on entrepreneurial orientation of both students will be implemented by conducting F-test and t-test. Secondly, the regression analysis between an independent variable - individualism - and dependent variables - innovativeness, internal locus of control, and entrepreneurial orientation - will be conducted in order to compare the effect of individualism on developing entrepreneurial orientation. Prior to implementation of two analysis, this study has implemented the survey to Korean and Chinese university students to estimate entrepreneurial orientation and a cultural variable to influence entrepreneurial orientation. The question of survey is divided into two parts - individual entrepreneurial orientation including internal locus of control and innovativeness and a cultural variable, individualism. As other precedent comparative studies of Chines and Korean potential entrepreneurship concluded, Chinese students have shown higher entrepreneurial orientation than Korean students. However, on the contrary to prior studies on cultural factors and entrepreneurship, only Chinese students' entrepreneurial orientation is influenced by individualism. Any dependent variables of Korean students were not affected by individualism variable.

Frankincense, the gum resin derived from Boswellia species, is complex mixtures composed of about $5{\sim}9%$ highly aromatic essential oil, $65{\sim}85%$ alcohol-soluble resins, and the remaining water-soluble gums. The anti-inflammatory properties of frankincense, alcohole-soluble resins, are well-recognized, but the question of whether aromatic essential oil also plays a role in the allergic asthma remains unanswered. This study was performed to evaluate anti-inflammatory effects of Boswellia sacra essential oil (BSEO) on ovalbumin (OVA)-induced asthma mouse model. BALB/c mice after intraperitoneal OVA sensitization were challenged with intratracheal OVA. One experimental group was inhaled with 0.3% BSEO for the later 8 weeks. BALB/c mice were sensitized and challenged with OVA and developed airway eosinophilia, mucus hypersecretion, and airway hyperresponsiveness. In contrast, the BSEO treated mice had reduced a number of eosinophils among BALF cells, goblet cell hyperplasia, and airway hyperresponsiveness. Cytokine analysis of BALF revealed that BSEO caused an increase in Th1 cytokine (interferon-$\gamma$ (IFN-$\gamma$)) and a decrease in Th2 cytokines (interleukin-4 (IL-4), IL-5 and IL-13) levels. In addition, the OVA-specific serum IgE and eotaxin levels were also reduced. In mice inhaled BSEO, $CD4^+$, $CD3^+/CCR3^+$, and $B220^+/CD23^+$ mediastinal lymph nodes cells were also decreased. These results suggest that inhaled BSEO as a immunomodulator in Th1/Th2 mediated asthma may have therapeutic potential for the treatment in allergic airway inflammation by a simple, cost-effective way.

Road traffic noise is closely related to road traffic environment, including traffic volumes by type and travel speed. In this study, we stated some issues and analyzed the relationships between road traffic noise and traffic flow characteristics. First, in attempt to find the answer to the question "When does the loudest traffic noise occur?" we reviewed the issue in the terms of traffic flow. As a result of analyzing level of service through Korea Highway Traffic Noise model, the actual maximum noise occurred in level of service D rather than level of service E, on the capacity state. It shows that maximum noise would be most likely to occur right before and after the peak hours. Second, this paper was looking for the method of a more easy and accurate traffic speed estimation to predict traffic noise. This paper proposed sketch planning techniques of speed-volume curve by level of service on Korea Highway Capacity Manual. As a result of trend line modeling, it was judged that quadratic form is a suitable function, and coefficient of determination ($R^2$) was higher than 0.96, respectively.
