Breast self-exam is easiest, safe and cost effective to be recommended as an important method for early detection of breast cancer. This experimental research with non-equal control design was to develop the efficacy expectation program for breast self-exam based on Bandura's self-efficacy information source. The study objects selected from two local churches in Busan. Twenty from S church were selected as a study group, twenty from D church as a control group. Efficacy expectation promoting program was based on Bandura's efficacy promoting source and was two hour lecture including slide, video tape, demonstration, pamphlet. After this, there were individual interviews with them and consultations through telephone f or verbal persuasion on the weekly basis between the first week and the fifth week. The effect from the experiment were measured on the first week after education and on the fifth week. Data from control group was collected during the period from Jan 11, 2 001 to Feb 15, 2001 and data from study group was collected during the period from Jan 12, 2001 to Feb 16, 2001. Measurement instrument for this study was developed by the author with the advice of specialist in order to measure self-efficacy and breast self-exam practice. Data analysis was done by using SPSS/10.0 PC program $with^2-$ test. t-test and ANCOVA. Proved results for hypothesis were as follows. 1) It was supported that "Study group educated by efficacy expectation promoting program has higher score in change rat e of self-efficacy than control group." (1 week after education F=18.395, p=.000 5 weeks after education F=28.972, p=.000) 2) It was supported that "Study group educated by efficacy expectation promoting program has higher score in change rate of exam practice than control group." (1 week after education F=37.984, p=.000 5 weeks after education F=28.972, p=.000) In conclusion, efficacy expectation promoting program for breast self-exam developed by this study may increase s elf-efficacy and breast self-exam practice.

In the early 90's, we had serious shortage of construction engineers in Korea. The shortage was acute especially in construction quality control and supervision area, which were gaining social attention due to the road bridge and the department store collapse that took the hundreds of lives in the early 90's in Seoul, Korea. In order to meet the high demand of construction engineers, the engineering license regulations were changed in 1995. Engineers who did not pass the written exam but have equivalent working experience are given engineering license to practice engineering legally. Since year 2000, while the severe engineer-shortage has been resolved, the opposite situation has occurred: there is serious over-supply of construction engineers. Policy makers and engineering practitioners are agreed to bring back the old-fashioned written exam engineer licensing system like before 1995, i.e., no more written exam exemption. However, the engineers who obtained license without taking written exam may not want to go back to old policy which would take their license. It is required to provide appropriate grace period before the new policy takes effect to minimize the impact of the changes. This paper forecasts the supply-demand of construction engineers providing the basis for the most appropriate policy changes.

The exam scheduling problem has been classified as nondeterministic polynomial time-complete (NP-complete) problem because of the polynomial time algorithm to obtain the exact solution has been unknown yet. Gu${\acute{e}}$ret et al. tries to obtain the solution using linear programming with $O(m^4)$ time complexity for this problem. On the other hand, this paper suggests chromatic number algorithm with O(m) time complexity. The proposed algorithm converts the original data to incompatibility matrix for modules and graph firstly. Then, this algorithm packs the minimum degree vertex (module) and not adjacent vertex to this vertex into the bin $B_i$ with color $C_i$ in order to exam within minimum time period and meet the incompatibility constraints. As a result of experiments, this algorithm reduces the $O(m^4)$ of linear programming to O(m) time complexity for exam scheduling problem, and gets the same solution with linear programming.

A novel approach for the detection of cheating during e-Exams is presented here using convolutional neural networks (CNN) based systems. This system will help the proctors to identify any kind of uncertain event at the time of online exams, for which most of the government's across the globe are recommending due to the Covid-19 pandemic. Most of the institutions and students across the globe are badly affected by their academic programs and it is a challenging task for universities to conduct examinations using the traditional methods. Therefore, the students are attending most of their classes using different types of third party applications that are available online. However, to conduct online exams the universities cannot rely on these service providers for a long time. Therefore, in this work, a complete setup of the software tools is provided for the students, which can be used by students at their respective laptops/personal computers with strict guidelines from the university. The proposed approach helps most of the universities in Saudi Arabia to maintain their database of different events/activities of students at the time of E-Exams. This method proved to be more accurate and CNN based detection proved to be more sensitive with an accuracy of 97% to detect any kind of uncertain activity of the students at the time of e-Exam.

Recent trends in globalization and informatization underscore the importance of logistics. As a result, there is a need for skilled and specialized logisticians. Third Party Logistics (TPL) and Supply Chain Management (SCM) require logisticians with a broad base of knowledge in areas such as multimodal transport, international trade, information technology computers, finance, operations management, etc. This study conducted a survey to find out the opinions of demanders and suppliers. The results of the surrey show that there are more skilled logisticians in the field of management, computer works in manager level and system management. The survey also found that the certificate exam, which the Ministry of Construction and Transportation started in 1997 as the "Certified Logistics Manager" exam, should have more questions in areas such as foreign languages, computers, logistics information, management skills, etc. To produce better logisticians in Korea, the government will have to invest more into their education, especially near the major ports and metropolitan areas. In addition, it is important that universities and companies work together to provide students with internship and other field-experience teaming opportunities. Logistics education centers should be built at the national level. In addition, the existing certification should be divided into two separate certifications: one for ordinary logistics, and one for international logistics. To further improve the certification system, short-answer or essay questions should be added to the second exam, and an additional certification for the highest level logisticians, a so-called "professional logisticians certificate," needs to be introduced.ntroduced.

Background: Cognitive impairment is a public health burden. Our objective was to investigate associations between work hours and cognitive function. Methods: Multi-Ethnic Study of Atherosclerosis (MESA) participants (n = 2,497; 50.7% men; age range 44-84 years) reported hours per week worked in all jobs in Exams 1 (2000-2002), 2 (2002-2004), 3 (2004-2005), and 5 (2010-2011). Cognitive function was assessed (Exam 5) using the Cognitive Abilities Screening Instrument (version 2), a measure of global cognitive functioning; the Digit Symbol Coding, a measure of processing speed; and the Digit Span test, a measure of attention and working memory. We used a prospective approach and linear regression to assess associations for every 10 hours of work. Results: Among all participants, associations of hours worked with cognitive function of any type were not statistically significant. In occupation-stratified analyses (interaction p = 0.051), longer work hours were associated with poorer global cognitive function among Sales/Office and blue-collar workers, after adjustment for age, sex, physical activity, body mass index, race/ethnicity, educational level, annual income, history of heart attack, diabetes, apolipoprotein E-epsilon 4 allele (ApoE4) status, birth-place, number of years in the United States, language spoken at MESA Exam 1, and work hours at Exam 5 (β = -0.55, 95% CI = -0.99, -0.09) and (β = -0.80, -1.51, -0.09), respectively. In occupation-stratified analyses (interaction p = 0.040), we also observed an inverse association with processing speed among blue-collar workers (adjusted β = -0.80, -1.52, -0.07). Sex, race/ethnicity, and ApoE4 did not significantly modify associations between work hours and cognitive function. Conclusion: Weak inverse associations were observed between work hours and cognitive function among Sales/Office and blue-collar workers.

Background: Pituitary pars intermedia dysfunction (PPID), a neurodegenerative disease leading to reduced dopamine production, is a common disease in aged horses. The treatment is based on administration of the dopamine agonist pergolide. This drug has been related to valvular fibrosis in humans, but the cardiovascular effect of this drug has not yet been investigated in horses. Objectives: To determine whether pergolide induces valvular disease in horses or affects the cardiac function. Methods: Standard, tissue Doppler (TDE) and two-dimensional speckle tracking (STE) echocardiography were performed in horses with diagnosed PPID based on adrenocorticotropic hormone dosage. Measurements taken in horses treated with pergolide were compared with those from untreated horses with nonparametric t-tests. Furthermore, measurements from follow-up examinations performed at least three months after the initial exam were compared with a Wilcoxon signed rank test for repeated measurements in each group. Results: Twenty-three horses were included. None of the 12 horses under treatment developed valvular regurgitation. Furthermore, no differences in the measurements of the left ventricular systolic or diastolic function could be seen between the group of horses with treatment and those without treatment. Measurements taken in the follow-up exam did not differ compared to those taken in the initial exam in both groups. Conclusions: No changes of the left ventricular function assessed by TDE and STE could be shown in a small population of horses with confirmed PPID. Treatment with pergolide did not affect the ventricular function nor induce valvular disease.
