The main cause of cervical cancer is a persistent infection with high-risk human papillomavirus (HR-HPV). Cervical cancer is reported as a preventable cancer in more than 80% of cases with early diagnosis and appropriate treatment. Papanicolaou test (Pap test) has been a global strategy to prevent cervical cancer, and recently, HPV test has been reported to be effective against cervical cancer and precancerous lesions. However, pelvic examinations give patients anxiety, discomfort, pain, distress, and psychological stress. HPV test via a urine sample caused less physical and psychological stress and more advantage than the Pap test. Therefore, it is necessary to study the usefulness of the HPV test for easy-to-collect urine samples. A total of 220 samples were collected from a pair of cervical and urine samples from 110 women and only 108 pairs of samples out of 110 were used because 2 cases were not amplified by β-globin. Among 108 pairs of cervical and urine samples, the prevalence of HPV was 37.0% (40/108) in cervical samples, 34.3% (37/108) in urine samples and HR-HPV was 22.2% (24/108) in cervical samples, 18.5% (20/108) in urine samples. In this study, urine samples showed a lower positive rate of HPV than cervical samples. There were many variables that could affect the condition of the urine sample. However, the HR-HPV agreement rate of the cervix and urine samples was 94.44% and the Kappa value was 0.823, which was "almost perfect". Through these results showed the significance of cervical cancer screening using a urine sample. Cervical screening is crucial, as cervical cancer can be prevented in more than 90% of cases. Urine samples collected by non-invasive methods may have the potential advantage of increasing acceptance of cervical cancer screening. Therefore, it is necessary to develop a new cervical cancer screening strategy using urine samples through further study based on the results of this study.

Six Sigma is a philosophy and systematic methodology for quality improvement. It encourages continuous quality improvement efforts to achieve the ideal goal of 6σ. Sigma(σ) is a statistic representing the standard deviation of the normal distribution, and 6σ level means a level where the tolerance of the specification is six times the standard deviation of the process distribution. In terms of the defective rate, the 6σ level achieves the 0.002 defectives per one million units. However, in the field, the 6σ level is used in the sense of achieving 3.4 defects per one million opportunities, which shows a large gap from the 6σ level in the statistical viewpoint. This is because field practitioners accept a 1.5σ shift of the mean of process when calculating the defective rate under sigma level. It said that the acceptance of 1.5σ shift of the mean is from experience, but there is no research or theoretical explanation to support it logically. Although it is a non-scientific explanation based on experience, considering that there has been no objection to the 1.5σ shift for a long time and it is rather accepted, it is judged that there is a reasonable basis for the 1.5σ shift. Therefore, this study tries to find a reasonable explanation through detective power of control chart via the run-rules to the 1.5σ shift empirically recognized by practitioners.
In introducing emissions trading schemes, many countries start with a high level of free allocation to reduce the sudden cost burden on companies and increase acceptance of the policy. The free allocation is then gradually reduced, considering the risks of carbon leakage. This aligns with the "polluter pays" principle and is often considered one of the elements of an advanced emissions trading scheme. In this context, this study uses a simple emissions trading market model to show that decreasing the free allocation rate may not be desirable if the emissions market is not perfectly competitive. In particular, by identifying the existence of a free allocation rate at which the cost inefficiency is minimized, this study demonstrates that having a low level of free allocation does not necessarily imply the improvement of the emissions trading scheme.
Purpose: School safety has recently become an important issue. In order to make a school environment safer, surveillance cameras have been installed in the facilities. The number of installations has been increasing rapidly since they have been considered widely recognizable and highly effective. However, conflicts between faculty and staff in installing and operating the system have also been increasing. In terms of school safety, these individuals'' cooperation is more than necessary. It is judged that looking into how they perceive the system could provide us with some suggestions on how to manage the related issues. The purpose of this study is to understand the perspective of faculty over closed-circuit television (CCTV) and make suggestions by analyzing their actions. Approach: In order to achieve the research objectives, I surveyed administrative actions such as the processing of official documents and CCTV policies for teachers and administrative staff of public schools in the Sejong Office of Education. In addition, I analyzed the behavior of those managing personal information and school safety-related documents along with the degree of complying with the policies. Finding: First, the correspondence rate of documents was high when there were designated document processors. Second, the acceptance level of documents in preschool was relatively low when there were designated processors. Third, the degree of accepting the policies and complying with them was higher in newly established schools than in existing schools. I found differences in the perception of how to handle the CCTV operations and the related work among the two groups of participants. In addition, I made suggestions on how to resolve the conflicts between them. Value: In this study, the education authorities quantified and measured the recognition and acceptance of faculty and staff regarding CCTV at each school level. Results showed that the active role of education authorities can make positive changes in how faculty and staff perceive the CCTV system and the problems surrounding it through school administrative action. In this regard, these results are meaningful in reducing the conflicts among the two groups and improving the organizational culture.
To improve the shelf-life of cherry tomato, samples were treated with aqueous chlorine dioxide ($ClO_2$) at 30 ppm for 0~30 minutes and the weight loss rate as well as the changes in physico-chemical and sensory properties of treated samples were investigated. Weight change in the control and in the samples with aqueous $ClO_2$ treatment were decreased slightly, and there were no difference during the storage period. There were no differences in soluble solid content among the treatments and during the storage period. There were no differences in the firmness of samples among the treatments but the firmness of the aqueous $ClO_2$ treated samples were decreased slower than that of the control samples. No significant changes in lightness, redness and yellowness of the controls and the samples by aqueous $ClO_2$ treatment were observed during 4 weeks storage period. The sensory parameters including taste, flavor, color, texture and overall acceptance at the initial period did not differ among the treatments. The scores for taste, texture and overall acceptance of the control were decreased faster than those of the aqueous $ClO_2$ treated samples when 3 weeks reached.
Background: To evaluate knowledge of Bangkok women regarding HPV and self-sampled HPV testing, and their attitudes towards testing. Materials and Methods: Thai women who had lived in Bangkok for more than 5 years, aged 25-to-65 years old, were invited to join the study. Participating women were asked to a complete self-questionnaire (Thai language), with literate assistance as needed. The questionnaire was divided into 3 parts: (I) demographic data, (II) knowledge and (III) attitudes towards self-sampled HPV testing. Before proceeding to Part III of the questionnaire, a 15-minute educational video of self-sampled HPV testing was presented to all participants. Results: Among 2,810 women who answered the questionnaires, 33.7% reported that they did not know about HPV. The characteristic features of these women were older age (> 50 years), lower income (< 600 USD/month), unemployed status, and non-attendees at cervical cancer screening. Only small numbers of women (4.6%) responded that they had heard about self-sampled HPV testing. After having information, 59.6% would not use the self-sampled HPV testing as a method of cervical cancer screening (non-acceptance). Factors significantly associated with the non-acceptance were older age, lower income, having no knowledge about HPV or self-collected HPV testing, a perception that the testing was unreliable and a concern that they might not be able to perform it correctly. Conclusions: Nearly half and almost all Bangkok women did not know about HPV and self-sampled HPV testing, respectively. Approximately 60% of Bangkok women refused to do the self-sampled HPV testing. Significant negative attitudes were concerns that the testing would be unreliable and a lack of confidence to perform the procedure correctly. Education about HPV and self-sampled HPV testing, ease of the procedure, or the testing models may increase rate of acceptability or positive attitudes.
This study explores the quality characteristics of white pan bread added with perilla leaf powder, and the results are as follows. The WRC(water retention capacity) of PLP (perilla leaf powder) added to the bread dough increased as the addition increased, and the initiation temperature during the rapid visco analysis (RVA) increased with more additions, showing significant differences. The highest and the lowest viscosity of the sample decreased as the powder added increased. The brightness(L value) of the bread without the powder was the highest, and the redness (a value) and the yellowness (b value) showed significant differences among the samples. Hardness increased showing significant differences among the samples as the powder added increased Chewiness was the highest but preference value was the lowest in the sample with 7% of the powder. The lowest score was shown in the color of the sample with the most PLP added. Flavor was the lowest of 4.93 in the comparison sample without the leaf powder added while bitter taste scored the highest of 5.21 in the sample of 3% powder added. It was also the highest in overall acceptance while the sample with the most powder showed the lowest of 4.03. From these results, it can be said that the preference of bread with PLP seems to decrease when more than 5% of PLP is added.

This study was conducted to optimize the processing conditions of seasoned laver Pyropia yezoensis with conger eel Conger myriaster seasoning sauce (CES) using response surface methodology (RSM). The RSM program results for bonesoftness showed that the optimum independent variables based on the dependent variables (Y1, lipid removal rate; Y2, texture; and Y3, sensory fish odor score) were 431.0% for X1 (water amount), 115.6℃ for X2 (retort-operated temperature), and 50.1 min for X3 (retort-operated time). The RSM program results for the CES blend showed that the optimum independent variables (X1, amount of bone-softened conger eel by-products; X2, mixed sauce amount; and X3, starch amount) based on the dependent variables (Y1, amino-N; Y2, Hunter redness; and Y3, drying time) were 44.8% for A (pre-treated conger eel by-product), 36.0% for B (mixed sauce), and 19.2% for C (starch). The RSM program results for seasoned laver with CES showed that the optimum independent variables based on the dependent variables (Y1, water activity; Y2, Hunter yellowness; and Y3, overall acceptance) were 5.0% for X1, (CES amount), 313.8℃ for X2 (roasting temperature), and 6.0 s for X3 (roasting time). The seasoned laver with CES prepared under the optimum conditions was superior to commercial seasoned laver in terms of overall acceptance.

The feasibility of incorporating cinnamon powder as a value-added food ingredient in cookies was investigated. Density of dough was not significantly affected by cinnamon powder (P>0.05). Moisture content, spread ratio, and loss rate of cookies decreased significantly with increasing levels of cinnamon powder (P<0.05). Lightness ($L^*$) and yellowness ($b^*$) decreased, whereas redness ($a^*$) as well as hardness increased significantly with higher amount of cinnamon powder (P<0.05). 1,1-diphenyl-2-picrylhydrazyl and 2,2'-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid radical scavenging activities were significantly elevated (P<0.05), and they were well-correlated. The consumer acceptance test indicated that addition of cinnamon powder to 4% had a favorable effect on consumer preferences in all attributes. Based on overall observations, cookies with 4% cinnamon powder can take advantage of the functional properties of cinnamon powder without sacrificing consumer acceptability.
