In this paper, we study the university timetabling problem, which consists of two subproblems, the university course timetabling problem and the examination timetabling problem. Given a set of classrooms, students, teachers, and lectures, the problem is to assign a number of courses (and examinations) to suitable timeslots and classrooms while satisfying the given set of constraints. We discuss the modeling and solution approaches to construct course and examination timetables for one of the largest Korean university. By using binary integer programming formulations, we describe these two complex real-world problems. Then, we propose a solution method, called NOGOOD, to solve the examination timetabling model. The computation results show that NOGOOD finds the optimal examination schedule for the given instance. Although we consider a specific instance of the university timetabling problem, the methods we use can be applicable to modeling and solving other timetabling problems.

The selection of the correct examination variables for diagnosing heart disease provides many benefits, including faster diagnosis and lower cost of examination. The selection of inspection variables can be performed by referring to the data of previous examination results so that future investigations can be carried out by referring to these selected variables. This paper proposes a model for selecting examination variables using an Artificial Bee Swarm Optimization method by considering the variables of accuracy and cost of inspection. The proposed feature selection model was evaluated using the performance parameters of accuracy, area under curve (AUC), number of variables, and inspection cost. The test results show that the proposed model can produce 24 examination variables and provide 95.16% accuracy and 97.61% AUC. These results indicate a significant decrease in the number of inspection variables and inspection costs while maintaining performance in the excellent category.

This study is carrying out a before and after experiment design for the non-equal comparative group to identify the effects of the breast self-examination education on breast self-examination participant education compliance and health promotion in women. The subject of this study was 58 women residing in Chungju. Their age ranged from 20 to 40. These women were not pregnant or did not breast feed, as well as they did not have any breast disease, at the time of survey. They were available for the response to the questionnaires, and understood the purpose of this study. They also agreed to participate in the study, and responded to the 3rd time questionnaires to the end. Thus, brochures and lectures were provided side by side to a group of 19 of those women, and only brochures were provided to another group of 39 of those women. With regard to education, a brochure and a program using a breast model were applied. Then, the frequency of the breast self examination compliance, breast self examination capability and the relations between the breast self examination and activities to promote health were measured, before the education, after 4 weeks of education and after 12 weeks of education. Before education and after 4 weeks of education. I collected the questionnaires myself visiting them, and after 12 weeks of education, the questionnaires were collected by mail. In relation to the study tool, the breast self examination activity was measured by two measuring tools: breast self examination activity frequency and breast self examination compliance capability. As for the frequency, the number of self examination for the period of 3 months, before the questionnaire survey, was measured in the form of self report. In relation to the tool to measure the breast self examination capability, the BSEPRI tool, which was developed by Wood in 1994, was used. Here, as the score was higher, the capability was indicated to be higher. The translated and revised version of Health Promoting Lifestyle Profile II (Walker, Sechrist & Pender. 2002) was used as a tool for health promotion. As the measured score was higher, the health promoting activity was indicated to be higher. The results of this study were as follows: 1. As a result of checking the breast self examination compliance frequency between the experiment group that received the breast self examination participant education and the comparative group that did not receive the education, there was a significant difference in interaction between groups by time, as time passed by. 2. As a result of checking the breast self examination compliance capability between the experiment group and the comparative group, there was a significant difference in interaction between groups by time, as time passed by. 3. As a result of carrying out a repetitive measurement analysis, between the experiment group that received the breast self examination education and the comparative group that did not receive the education, which was carried out to validate the hypothesis that the former would have higher health promoting activities than the latter, there was no significant difference after the breast self examination education was conducted.

Breast cancer ranks as one of the major health problems in adult women. The purpose of this study is to determine relationships among the practice of Breast Self-Examination(BSE) and the variables of cancer risk and other genernal factors. This knowledge may be helpful in designing a BSE educational program to promote breast self-examination on a regular basis. The study population included 205 women who live in K city. Personal interviews were conducted to determine the individual's breast self-examination behavior, the level of Breast Cancer Risk according to general factors as well as her reasons for not doing a breast self-examination. The collected data was analyzed with an SAS program The results were summarized as follows : 1. The level of Breast Cancer Risk of the subjects is as follows: high risk(9%), moderate risk(11%), boderline risk(12%), no increased risk (68%). 2. There was no difference in the practice of BSE between women who were at high cancer risk and at no increased cancer risk. 3. BSE practice levels according to general foctors were significantly related to the residence and the level of education of the subjects. The performing of regular breast self-examination in urban areas was 7% and in rural areas was 0%. Regularly practiced breast self-examination in women with a low education was 5% and in college educated women, it was 29%. 4. BSE education was significantly related to the residence and the level of education of the subjects. The majority learned BSE through 'a magazine or journal'. 5. The reason of the majority of women did not perform a regular breast self-examination was, 'Didn't know the BSE technique'. On the basis of this study it can be concluded that the development of a BSE education program is needed to help women perform the examination correctly.

Purpose: The present study was aimed to examine the usefulness of 18F-FDG PET/CT in the evaluation of cervical lymph node metastasis in patients with oral cancer. Materials and methods: Twenty-two patients who underwent neck dissection to treat oral cancer were subjected for examination. The cervical node metastasis was evaluated by means of clinical examination, CT scan, PET, and histologic examination. By comparing the results of each examination modality with those of histologic examination, it's sensitivity, specificity, positive predictive value, and negative predictive value were determined. Results: The oral cancer was more frequent in males with a ratio of 2.14:1. The sixth decade showed the highest incidence in age distribution with mean of $56{\pm}16$. Histologic findings showed that squamous cell carcinoma was the most common (15 patients), and mucoepidermoid carcinoma (3), malignant melanoma (2), and adenoid cystic carcinoma and ghost cell odontogenic carcinoma (1 each), in order. In most cases, wide surgical excision of the primary cancer and neck dissection was performed, followed by reconstruction with free flaps when necessary. When comparing the results of each examination modality with those of the histologic examination, clinical examination showed sensitivity, specificity, positive predictive value, and negative predictive value at 11%, 85%, 33%, and 58%, respectively. CT scans showed at 67%, 77%, 67%, and 77%, while $^{18}F$-FDG PET/CT at 78%, 77%, 70%, and 83%, respectively. Conclusions: These results suggest that PET is more useful, compared with clinical examination and CT scans, in the evaluation of cervical lymph node metastasis in patients with oral cancer.
