Previous polarity classification using sentiment analysis utilizes a sentence rule by product reviews based rating points. It is difficult to be applied to blogs which have not rating of product reviews and is possible to fabricate product reviews by comment part-timers and managers who use web site so it is not easy to understand a product and store reviews which are reliability. Considering to these problems, if we analyze blogs which have personal and frank opinions and classify polarity, it is possible to understand rightly opinions for the product, store. This paper suggests that we extract high frequency vocabularies in blogs by several domains and choose topic words. Then we apply a technique of sentiment analysis and classify polarity about contents of blogs. To evaluate performances of sentiment analysis, we utilize the measurement index that use Precision, Recall, F-Score in an information retrieval field. In a result of evaluation, using suggested sentiment analysis is the better performances to classify polarity than previous techniques of using the sentence rule based product reviews.

Background: Cancer registration data is used to understand the nation's cancer burden, and to provide significant baseline data for cancer control efforts, as well as, research on cancer incidence, mortality, survival, and prevalence. A system that approves, assesses, and manages the qualification of specialists, responsible for performing cancer registration, has not been developed in Korea. This study presents ways to implement a certification system designed for the qualification of tumor registrars in Korea. Materials and Methods: Requirements for implementing a certified tumor registrar qualification system were determined by reviewing the system for establishing qualifications in Korea and the American qualification system via the National Cancer Registrars Association (NCRA). Moreover, a survey was conducted on Korean medical records administrators, who had taken the U.S. Certified Tumor Registrar (CTR) examination, in order to review their opinions regarding these requirements. Results: This study verified the feasibility of a qualification examination based on the opinions of CTR specialists by determining the following: items, and the associated ratings, of the qualifications necessary to register individuals as certified tumor registrars in a private qualification system; status of human resources required for the examination or training processes; plans regarding the organization needed for management, and operation of qualifications, examination standards, subject areas, examination methods, examination qualifications, or education and training programs. Conclusions: The implementation of a certified tumor registrar qualification system will lead to enhanced job competency for specialists and a qualitative improvement of cancer registration data. It will also reliably foster human resources that will lay the groundwork needed to establish scientific and reasonable national cancer management policies.

Objective: In accordance with the changing demographics in the United States, orthodontists working on various ethnic populations should be more conscious when using the standardized profile analyses for the African American patient. The objective of this study was to examine whether the perception of lip protrusiveness in modern African American faces has changed. For this purpose, we investigated the most favorable African American lip profile using the opinions of 10 experienced and 10 newly trained younger orthodontists. Methods: Attractiveness was converted to a number on visualized analog scales. Comparative ranks on 16 African American profiles, with focus on lip protrusiveness and thickness, were made among the groups. Mixed-effects linear regression models were fit and group differences were estimated. Results: Younger orthodontists favored a more protrusive lip profile, and the variance in their perceptions was narrower than those of older orthodontists. Measurements related to upper lip protrusion showed the strongest correlation to attractiveness (r = -0.82). The association with attractiveness decreased linearly as the protrusiveness of the upper lip increased. Steiner's E-line was the most influential reference for determining the level of attractiveness for the older orthodontists, whereas upper lip protrusion was the most influential factor for the young orthodontists. Conclusions: An adequate level of lip protrusiveness and thickness should be essential for maintaining attractive esthetics in African American patients. Yet, a new set of standards for prominent lips in this population is necessary to reflect the current trend in the concept of a beautiful face in the modern world.

Objective I would like to identify when 'If the wind damage people, they feel aversion to wind. If the cold damage people, they feel aversion to cold.(傷風則惡風 傷寒則惡寒)' has appeared and what does this hypothesis have affected. I also researched future scholars' opinions and their criticism on this hypothesis. Methods: 1. Among the books which are related to Cold damage according to the age, books which have original text that has a relationship with this hypothesis were elected. Total of 30 books were elected, and their original text was extracted and analyzed. Results 1. This hypothesis appeared first on Hwalinseo(活人書) in the Song Dynasty, and had lots of impact on future generations. 2. After passing Song, Yuan, and Ming Dynasty, there were some opinions appeared which criticized part of this hypothesis. Dongeuibogam(東醫寶鑑) also tried to correct this hypothesis. 3. Bang Yu-Jip(方有執) of Ming Dynasty straightly opposed this hypothesis on Sanghanronjobyeon(傷寒論條辨)for the first time. It had huge influence in the Qing Dynasty and lots of scholars suggested that this hypothesis lacks persuasion. 4. Just like Qing Dynasty, this hypothesis is not accepted in the books of modern ages. Conclusion This hypothesis appeared in the Song Dynasty for the first time and had lots of influence, but some counter arguments had appeared as time passed, and during Qing Dynasty, this hypothesis lost its creditibility with lots of criticism.

Pediatric home-based physical therapy (PHBPT) provides professional rehabilitation programs at the patient's home, where the activities of daily life are actually performed. PHBPT also allows to avoid the difficulties of transporting children with disabilities to the clinic. Despite these advantages, PHBPT is not yet widely practiced in Korea. There is little objective information regarding the opinions of the main stakeholders on PHBPT. To investigate the awareness and demand of PHBPT among the main stakeholders, 41 pediatric physical therapists (PT) (of 60 contacted) were recruited from different regions of Korea on the basis of the regional population distribution. The recruited PTs completed their questionnaires and also participated in collecting questionnaires from 35 medical doctors (MD) with whom they worked and from randomly selected 201 parents of children with disabilities recruited. The overall response rate was 85.5%. The awareness of PHBPT differed between PTs (95.1%) and parents (67.2%) (p<.001). The survey showed that 82.9% of MDs had at least heard about PHBPT. Significantly more parents (83.5%) than MDs (57.1%), and 70.0% of PTs, wanted to start PHBPT service immediately (p<.001). Significantly more parents (90.0%) than PTs (73.2%) were willing to participate in PHBPT (p<.001). Opinions on the details of policies and procedures (i.e., necessity for prescription, treatment cost, and treatment frequency) differed among the respondent groups, but all favored a minimal qualification of 6~10 years of pediatric experience and a treatment session duration of 1 hour. These findings provide objective information to support health service administrators to understand the current demand and develop feasible policies and procedures of PHBPT in Korea.

Purpose: Seasonal influenza can be prevented by vaccination. Disease prevention in children aged <60 months is of particular importance because of the associated familial and societal burden. Considering that caretakers make the decision to vaccinate their children, the identification of drivers and barriers to vaccination is essential to increase influenza vaccination coverage. Methods: A total of 639 parents participated in the pre- and posteducational survey and 450 parents participated in the study via telephone interviews. The participating parents were asked to rank their agreement with each statement of the survey questionnaire on a scale from 1 (strongly disagree) to 5 (strongly agree), and the scores between pre- and postintervention were compared. Results: Before the educational intervention, 105 out of 639 participants reported not to agree to vaccinate their children against influenza. After the intervention, 46 out of the 105 parents changed their opinions about childhood vaccination. The physicians' recommendation received the highest agreement score and was the most important driver to vaccination, whereas the cost of vaccination was the strongest factor for not vaccinating children. In general, the participants significantly changed the agreement scores between pre- and postintervention. However, the unfavorable opinions about vaccination and the convenience of receiving the influenza vaccine did not change significantly. Conclusion: The results of this study indicate that a specific educational intervention involving caregivers is very effective in increasing the influenza vaccination coverage of children aged less than 60 months.

We conducted a systematic review to summarize providers' attitudes toward pay-for-performance (P4P), focusing on their general attitudes, the effects of P4P, their favorable design and implementation methods, and concerns. An electronic search was performed in PubMed and Scopus using selected keywords including P4P. Two reviewers screened target articles using titles and abstract review and then read the full version of the screened articles for the final selections. In addition, one reference of screened articles and one unpublished report were also included. Therefore, 14 articles were included in this study. Healthcare providers' attitudes on P4P were summarized in two ways. First, we gathered their general attitudes and opinions regarding the effects of P4P. Second, we rearranged their opinions regarding desirable P4P design and implementation methods, as well as their concerns. This study showed the possibility that some healthcare providers still have a low level of awareness about P4P and might prefer voluntary participation in P4P. In addition, they felt that adequate quality indicators and additional support for implementation of P4P would be needed. Most healthcare providers also had serious concerns that P4P would induce unintended consequences. In order to conduct successful implementation of P4P, purchaser should make more efforts such as increasing providers' level of awareness about P4P, providing technical and educational support, reducing their burden, developing a cooperative relationship with providers, developing more accurate quality measures, and minimizing the unintended consequences.
