  • High-risk human papillomavirus (HPV) genotypes are the major cause of cervical cancer. Hence, HPV genotype detection is a helpful preventive measure to combat cervical cancer. Recently, several HPV detection methods have been developed, each with different sensitivities and specificities. The objective of this study was to compare HPV high risk genotype detection by an electrochemical DNA chip system, a line probe assay (INNO-LiPA) and sequencing of the L1, E1 regions. A total of 361 cervical smears with different cytological findings were subjected to polymerase chain reaction-sequencing and electrochemical DNA chip assessment. Multiple infections were found in 21.9% (79/361) of the specimens, most prevalently in 20-29-year olds while the highest prevalence of HPV infection was found in the 30-39-year age group. The most prevalent genotype was HPV 16 at 28.2% (138/489) followed by HPV 52 at 9.6% (47/489), with the other types occurring at less than 9.0%. The electrochemical DNA chip results were compared with INNO-LiPA and sequencing (E1 and L1 regions) based on random selection of 273 specimens. The results obtained by the three methods were in agreement except for three cases. Direct sequencing detected only one predominant genotype including low risk HPV genotypes. INNO-LiPA identified multiple infections with various specific genotypes including some unclassified-risk genotypes. The electrochemical DNA chip was highly accurate, suitable for detection of single and multiple infections, allowed rapid detection, was less time-consuming and was easier to perform when compared with the other methods. It is concluded that for clinical and epidemiological studies, all genotyping methods are perfectly suitable and provide comparable results.

  • 1. Objectives : This research aimed to understand the effects of food consumption that fits to the constitution of subjects on health status by recognizing the constitutional food preference according to Sasang constitution. 2. Methods : The participants who are college students in D city were invited from Mar. 17, 2009 to Sep. 5 2010 for the research. More than two medical doctors who are specialized in Sasang constitution diagnosed the constitution of participants, and the participants were selected as subjects only if the diagnosis of the two doctors were agreed. Total 422 subjects (Taeumin: 175, Soeumin: 101, Soyangin: 144) were selected from the diagnosis, and the collected data was analyzed with computer software of SPSS 17.0. The frequency analysis was executed for the general characteristics of subjects, and the relationship of constitutional food preference and health status (SF-36) were analyzed with Pearson Correlation Coefficient. 3. Results : From the results about the distribution of constitutional food preference according to the constitutions, Soeumin showed the highest frequency for both of lower than 10 points (35.0 %), which stands for high preference of constitutional food, and higher than 40 points (1.9 %), which stands for low preference of constitutional food. And, they showed no correlation for the results about the relationship between health status and constitutional food preference based on 9 sub-categories of SF-36 including Physical Component Score (PCS), Mental Component Score (MCS). 4. Conclusions : In conclusion, the effects of food consumption that fits to the constitution of the twenties on their health status were understood by recognizing the constitutional food preference according to Sasang constitution. Comparing with the previous research results that constitutional food consumption can enhance their health status, there were no correlation between health status and constitutional food preference. The discrepancy of results can be addressed to difficulties of group selection, constitutional food categorization and lack of constitutional food-related questionnaires. Thus, it is required to conduct a follow-up studies that were made up for the mentioned shortcomings.

  • An attempt was made to survey soybean cultivars that were nonsensitive to the photoperiod for selection as possible breeding materials for wide area adaptable varieties. Fifty-five cultivars were subjected to different day length conditions. The number of days from sowing until flowering was shortened under short day length conditions, and late varieties tended to be more sensitive to day length than early varieties. The response to day length of the tested cultivars might be divided into three groups; low, intermediate and high degree, by their accelerated rate of flowering. Especially four varieties in the low responding group, Gembokin, Wirth, Wayne and Pi.54613 were identified to be nonsensitive to day lengths, that is, neutral varieties. They also showed little variation in morphological characteristics under different day length conditions.

  • Complementary and alternative medicine (CAM) has gained in popularity among cancer patients in recent years. The use of CAM in cancer patients is common with about one third of patients using some form of CAM in Western countries. The purpose of this study was to analyze the use of CAM and determine what factors affect to use CAM among cancer patients to provide CAM therapy information and assist therapy selection among various CAM therapies to cancer patients. The design of the study was descriptive cross-sectional, and data were collected using a 16-item questionnaire. This study was conducted in subjects with confirmed diagnosis of stomach, colon, liver, or pancreas cancer, in both out-patients clinics and inpatients setting in a tertiary hospital in Seoul Korea. As a result, among the participants, past or current CAM use was reported by 75%, which shows a statistically significant difference in income groups(P<0.05), but no difference in age and religion groups. The most common therapies use by cancer patients included traditional Korean medicine (32.1%), folk remedies (26.6%), exercise (14%), dietary supplements (11.6%), physical therapy (9.9%), diet therapy (5%), and meditation (4%). 77.8% of patients show satisfaction and 64.4% shows perceived effectiveness of CAM. Male patients with higher income, and previous treatment were more likely to use CAM. The main benefits from CAM reported by cancer patients were psychological improvement and symptom improvement. Of the cancer patients used CAM, 30.9% were dissatisfied, 25.8% did not have benefits from the use, and 7.6% experience side effects. Cancer patients who prefer CAM (more than 3 kinds) used it to cure cancer, on the contrary, the one who do not prefer CAM used to improve symptoms and psychological stability. The main sources of information about CAM were family and friends(54.4%), and media(24.5%), doctor and nurse(18.3%), and religion group(2.6%). Findings suggest that due to the relatively high use of CAM among cancer patients in Korea, this topic should be taken into account in the development of a holistic approach to cancer patients and efficient cancer patients management system and proactive and consistent management of CAM is necessary in the health care system in Korea.

  • Ranking-based conjoint analysis(RBCA) and choice-based conjoint analysis(CBCA) have attracted significant interest in various fields such as marketing research. When conducting research, the researcher has to select one suitable approach in consideration of strengths and weaknesses. This article performs an empirical comparison of the predictability of RBCA and CBCA in order to provide criterion for the selection. A new concept of measurement set is developed by combining the ranking set and choice set. The measurement set enables us to apply two approaches separately on the same consumer group that allows a fair comparison of predictability. RBCA and CBCA are conducted on consumer preferences for RTD-coffee; subsequently, the predicted values of market shares and hit rates are compared. The study result reveals that their predictabilities are not significantly different. Further, the result indicates that RBCA is recommended if the researcher wants to improve data quality by filtering out poor responses or to implement the market segmentation. In contrast, CBCA is recommended if the researcher wants to lessen the burden on the respondents or to measure preferences under similar conditions with the actual marketplace.

  • This research was carried out in order to develop and validate the Korean Version of Working Relationship Scale for Mentally Disabled Persons, which measures the working relationship between a mentally disabled person and his or her case manager. The first step taken to develop this scale was to construct sample items for the Working Relationship Scale using literature research and three focus group interviews of mentally disabled persons who use local mental health services. Secondly, mentally disabled people were surveyed with these sample items and two professors from the department of social work who specialize in mental health social work and two licensed mental health social workers working in the community mental health field reviewed these sample items to select and compile a final version of the scale. Lastly, the scale's reliability and validity was verified through an empirical study of 569 mentally disabled persons who surveyed the final selection of items. An explanatory factor analysis showed that the sample items can be grouped into three factors. Factor 1 is 'Professional Contribution Factor,' which is related to the professional practice of the case manager; Factor 2 is 'Negative Working Relationship Factor'; and Factor 3 is 'Emotional Bond Factor,' which measures the intimacy between the case manager and the mentally disabled person. A confirmatory analysis of the three-factor format that was discovered in the explanatory factor analysis was carried out with the rest of the randomly divided data, which showed that the model demonstrated a goodness-of-fit. The convergence validity between similar concepts appeared to be appropriate as well. Based on these results, the Korean Version of Working Relationship Scale for Mentally Disabled Persons consisting of a final 33 items is developed and proposed and its implications in social work are discussed.

  • In this paper, we develop the high-risk drinking predictive model in Korea using the cross-sectional data from Korea Community Health Survey (2014). We perform the logistic regression analysis, the decision tree analysis, and the neural network analysis using the data mining technique. The results of logistic regression analysis showed that men in their forties had a high risk and the risk of office workers and sales workers were high. Especially, current smokers had higher risk of high-risk drinking. Neural network analysis and logistic regression were the most significant in terms of AUROC (area under a receiver operation characteristic curve) among the three models. The high-risk drinking predictive model developed in this study and the selection method of the high-risk intensive drinking group can be the basis for providing more effective health care services such as hazardous drinking prevention education, and improvement of drinking program.

  • This study analyzes the middle school Home Economics textbook's 'Adolescence consumption life' unit using framework of Education for Sustainable Development(ESD) to examine correlation with the current Home Economics ESD, and aims to provide the base data for the composition of the educational curriculum that can help the students cultivate the capability for leading sustainable life from the future oriented perspective and for the selection of educational contents. This study analyzes the 'Adolescence consumption life' unit in the Home Economics textbook of the 12 type revised curriculum of 2009. As for the analysis method, Romey's content analysis method is used to carry out in-depth analysis of the ESD content elements. The analysis demonstrates the following. First, content elements extracted commonly from the 'Adolescence consumption life' unit are analyzed with the ESD's criteria of analysis (environment, economic and social domain), which led to the composition with the sub content elements following 23 related topics. Secondly, content elements of 12 types of Home Economics textbook's 'Adolescence consumption life' unit used in middle school are analyzed in three domains, which led to social domain (68%), economic domain (58%) and environmental domain (40%) in the order mentioned. This focused on the role of the Adolescent-consumer on the active consumer that is presented in the 2009 revised educational curriculum, and it is possible to see that this is very closely related to the right to organize and to be active in terms of the human safety, consumption culture, social interest and group.

  • This study aims to develop biology teachers' education program based on argumentation activity about core concepts of evolution and to analyze the characteristics of core concepts of evolution learned during the program. The eight core concepts of evolution in this study were variation, heritability of variation, competition, natural selection, adaptation, differential reproductive rate of individuals, changes in genetic pool within a population, and macroevolution. The performances of teachers participating in the program were compared before and after argumentation activities; consisting of seven sessions on the eight core concepts of evolution. The process of the program was specially designed by learning cycle model for teacher education, consisting of seven phases: identification of the task, production of a tentative argument, small group's written argument, share arguments with the other groups, reflective discussion, final written argument, and organization by an instructor. Participants in the study were two pre-service biology teachers and four in-service biology teachers. The results suggest that biology teachers reduced the teleological explanation for biological evolution and improve its adequacy after the intervention. Teachers lacked the opportunity to discuss variation, heritability of variation, competition, and macroevolution because science textbooks lack information on the concepts of biological evolution. The results of this study suggest that because the argumentation program developed for teachers helps to improve understanding the concepts of evolution and to reduce inadequate conceptions in biology, teacher education programs using argumentation activity and eight core concepts of evolution will play a role for efficient evolution education for biology teachers.

  • With the opening of healthcare market, the health care environment in Korea is anticipating a drastic change. In this Internationally open market environment, it is necessary to introduce a systematic health care plan and DRG system which offer qualitative medical services as well as reduced cost. Purpose of this study is to develop and test the critical pathway for Cesarean section patient in the way to be possible the integrated inpatient management. It was adopted the process of six phases to develop the critical pathway as the theoretical framework implemented by Johns Hopkins Hospital, Maryland, U.S.A. In the first phase, make a selection of diagnosis/procedures to develop. In the second phase, organize a development team consisted of eight expertises working in maternity nursing area. In the third phase, analyze the overall medical service offered to patient through review medical records and decided the service content and the implementation period for the Cesarean section patient. In the forth phase, make out a preliminary critical pathway after verification of expert group on content validity. In the fifth phase, validity operate to ten Cesarean section patients to test implementation in practice by using the preliminary critical pathway, In the sixth phase, defined the final critical pathway. The result of this study was as follows. 1. There were classified 8 categories as monitoring/assesment, treatment, medication, activity, diet, test, consult, education/discharge plan for vertical axis and showed hospital stayed from admission to discharge for horizontal axis of critical pathway through analysis 68 Cesarean section patients medical records. 2. After critical review 68 medical records to make out a preliminary critical pathway, hospital stays for horizontal axis were showed 6 days, mean hospital stays were 7.5 days, 2.1 days were to be taken operation after admission and 4.2 days were stayed until discharge after operation. 3. After making out a questionare in 90 items of a medical service content of eight categories and verifying the content validity of expertises, the 85 items of the preliminary critical pathway were selected by expertises agreement over 88% and modified or deleted 5 items showing agreement below 75%. 4. After verifying a validity to 10 patients for 4 weeks, hospital stays were 5.9 days. There were deleted 1 item and modified or supplemented the 9 items of the 10 items.
