Objective : To study risk factors of secondary lumbar discectomy (LD) for recurrent herniated lumbar disc (HLD) and identify methods to lower the rate of recurrence. Methods : Data from 160 patients who underwent primary LD were collected retrospectively. Demographic features, radiologic findings including Pfirrmann disc degeneration, and surgical information were analyzed to compare risks between revision and non-revision patients. Results : The revision rate was 15% (24 patients), and the mean follow-up was 28.3 months. HLD recurrence was not related to any demographic characteristics. Primary and secondary LD were most common at the L4-5 level, but the level of operation was not significantly associated with revision. Primary LD most commonly had a Pfirrmann disc degeneration grade of 3, followed by 4. For recurrent HLD, Pfirrmann grade 4 was most common and was statistically significant (p<0.05). A body mass index (BMI) over 30 was considered obese and was significantly related with HLD revision (p<0.05). Conclusion : Patients with high BMI or severe disc degeneration should be informed of HLD revision.

The rapidly increasing rate of shoulder arthroplasty is certain to increase the number of revision arthroplasties because of parallel increases in complication numbers. It has been widely reported that the causes of revision shoulder arthroplasty include rotator cuff deficiency, instability, glenoid or humeral component loosening, implant failure, periprosthetic fracture, and infection. Revision arthroplasty can be technically challenging, and surgical options available for failed shoulder arthroplasty are limited, especially in patients with glenoid bone loss or an irreparable rotator cuff tear. Furthermore, the outcomes of revision arthroplasty are consistently inferior to those of primary arthroplasty. Accordingly, surgical decision making requires a good understanding of the etiology of failure. Here, we provide a review of indications of revision arthroplasty and of the surgical techniques used by failure etiology.

The arbitration rule of CIETAC was vastly revised and was put in force on May 1, 2005. By its revision, China has improved its arbitration system. Chinese arbitration law had many problems when it was enacted in 1995, but the problems could not be avoided because of the poor surroundings for arbitration in China. As China has not had much experience in operating its legal system effectively, and also has little in the way of studies on legal theory that would allow it to deal with its laws in a flexible manner, authorities usually wait to revise a law until enough relevant experience has been accumulated. Therefore, during the 10 years since its enactment, China has resolved the problems within its arbitration law through revision of arbitration rule rather than by revision of the law itself. As this law is a basic one in ruling the arbitration system in China, there are some limitations as to how far the system can be developed through revision of arbitration rule alone. In spite of the limitations, the revision in 2005 contributed a great deal to resolving the existing problems within Chinese arbitration law. The biggest problem in the arbitration law is the Chinese arbitration law that restricts party autonomy. With the revision of the arbitration rule, many problems concerning party autonomy were circumvented. This occurred because the arbitration rule now provides parties the opportunity to choose arbitration rule other than the CIETAC arbitration rule, and even allows parties to agree to amend articles in the CIETAC arbitration rule -- a very important revision indeed. In addition to party autonomy, there are other improvements for example, there is an enhancement of the independent character of the CIETAC, clearing of jurisdiction, easing in the formation of arbitration agreement, improvement in the way arbitrators are chosen, and enhancement in the cultural neutrality of the arbiter. Problems still remain that can only be solved by revision of the arbitration law itself. These problems relate to the governing law of the arbitration agreement, the collection of evidence, custody of property, selection of chief arbiter, interlocutory awards, etc. In addition, some non-legal problems must also be resolved, like the actual judicial review of arbitration awards or difficulties of executing arbitration awards.

With the recent announcement of the WCAG2.2 Work Draft of the W3C, revision of the WCAG2.2 guidelines will be made soon. Consequently, the revision of KWCAG2.1 in response to changes in the domestic and international environment of web accessibility is urgent. The revision primarily involves development and selection of web accessibility evaluation items. In this study, the efficient procedures and useful methodologies for developing and selecting the evaluation items are to be presented. FGI (Focus Group Interview) has been devised to reflect every stakeholders opinion fairly. GT (Group Technology) has been applied to expedite the revision processes particularly in the FGI. QFD (Quality Function Deployment) method plays an important role in investigating the relationship between evaluation items and its characteristics, and in analyzing the importance and priorities of each item. This study proposes 5 principles, 17 guidelines and 39 evaluation items which can be used for the revision of KWCAG 2.1. This study is expected to be of great help in establishing the KWCAG 2.2 in the near future.

It is reported that approximately 100,000 anteior cruciate ligament (ACL) reconstructions are performed in the United States each year. Recurrent instability because of graft failure is estimated to occur in from 0.7$\%$ to 8$\%$ of reconstruction. Recently revision ACL reconstruction is likely to become more common as the number of primary reconstructions continues to increase. Arthroscopic revision ACL surgery with adequate graft for failed ACL reconstruction was successful in objectively and subjectively improving stability. However, considering the most common causes of failure after ACL reconstruction were errors in surgical technique, it is important that the primary ACL reconstruction should be performed with correct surgical technique. Therefore author reviewed the causes of failure of reconstruction to prevent the failure of reconstruction and described the surgical technique of revision ACL reconstruction.

Objectives: The purpose of the study was to investigate the basic materials required for law revision regarding dental hygienists through perceptions and opinions of legislation amendments. Methods: The study was conducted from April 23, 2016. A self-reported questionnaire was completed by 797 dental hygienists in Seoul and Gyeonggido after receiving informed consent from institutional review board (IRB No. PO1-201602-23-001). Results: Necessity for dental hygienist-related medical law revision accounted for 92.4% and 85.4% of dental hygienists replied that specialized dental hygienist system must be established. The reasons for medical law revision were as follows; roles and education of medical technicians (60.6%), settlement of medical legal problems (48.0%), cooperation with other organizations (29.0%), political negotiations (17.4%), and national consensus (9.5%). The score for 'possible to get legal protection by the system establishment of roles and work scope of dental hygienists' was 4.11 of 5 points. Conclusions: It is important to establish the job scope of dental hygienist. The revision of dental hygienist-related law will help to enhance the status of dental hygienists as professional medical technicians in the future.

The Purpose of this study was to analyze STS contents in elementary school science textbooks according to 6th, 7th and revision 2007 national curriculum. The contents of STS were analyzed by the STS elements of Yager and the STS topics of Piel's standard. Major findings from the analyses are as follows: (1) The STS contents in the science textbooks of the 6th curriculum took up 13.7% and increased to 18.3% in the 7th and 19.0% in the revision 2007, which showed that the textbooks followed the goal of the national curriculum faithfully. (2) Based on the STS elements by Yager's standard, most of STS content is focused on 'Application of science', 'Social problems and issues' and 'Local and community relevance'. (3) Based on the STS topics by Piel's standard, most of STS contents are focused on 'Effect of technological development' and 'Society of science'. These results indicate that recent STS education trends are reflected on the 6th, 7th and revision 2007 textbooks well. However, it is suggested that some improvement is needed, such as diversification of topic.
