This study compares blogs of professional reporters with those of citizen reporters in terms of watchdog and interactivity functions. Watchdog function was analyzed in light of the extent of soft news and the degree of critical relationship with the government. Interactivity was assessed by analyzing readers' comments on the articles of reporter blogs. for citizen journalism and for professional one were chosen in order to minimize any discrepancies caused by ideological differences. As a result of the content analyses, citizen reporter blogs were found to deliver soft news more frequently than those of , whereas the former had stronger tendency to maintain the critical relationship with the government than the latter. As for the interactivity function, although the number of comments uploaded to citizen reporter blogs was higher than that of professional reporter blogs, the latter was found to meet the standards of communicative interaction more adequately than the former.

This study examines how the watchdog concert in journalism field has been created and develope4 Related studies found that the watchdog is related not so muck with free press theory as with a privilege awarded to the press because the press serves for the public interests. It was found that in the U.S., the watchdog concept was derived from the a lot of libel cases in the late 1890s. At the time, the newspaper owners and editors continuously claimed the very protection over vulnerability of newspaper's collecting, reporting, and printing news. While, in Korea, the concept of watchdog emerged in the late 1990s after the establishment of the Constitution Court. Even though the watchdog concert was accepted very late by the Korean courts, it is believed to be a kind of special privilege to prevent the press from being recklessly regulated in libel cases. Rather, the Korean courts expand the extent of the role of the press as a watchdog by deciding that not only the public officials and politicians but also other socially influential public figures could be included in the criticism from the press. However, how these court decisions can be practically implemented depends upon how the court apply the probability of the press to believe the news true and intention of malice in writing and publishing the stories.

Purpose: To evaluate the effectiveness of ultrasonography-guided multiple needling for calcific tendinitis of the shoulder. Materials and Methods: We included 18 symptomatic calcific tendinitis patients who underwent ultrasonography-guided multiple needling and followed for average 17 weeks. The procedures were multiple needling or aspiration of the calcific deposit and injection of local anesthetics and steroid into the subacromial bursa under the ultrasound control. Clinical improvements were evaluated using pain VAS, UCLA score and KSS score. The size and status of calcific deposits were compared. Results: A significant improvement was seen in pain VAS, UCLA score and KSS score (p<0.05). At the final follow up, the calcific deposits had resolved completely of nearly completely in 39%, and the size was decreased in 61%. Conclusion: Ultrasound-guided multiple needling is considered as a useful method which could provide prompt pain relief and reduce calcific deposit for calcific tendinitis of the shoulder.

The power of media has always been problematic in the countries of full press freedom. Originally, the media used to be an effective vehicle for communication within human beings. However, it exerts an overwhelming power toward human society. Through applying the well-known four dog models in terms of media function, this study attempts to examine how the press media in South Korea transformed themselves into another powerful independent organization or institution after regime shift in 1987. The whole editorials of four sampled newspapers were analyzed through frame analysis model. The ChosunIlbo, known as a conservative and pro-government paper, shows to take the role of supporting chaebol policies under Roh TaeWoo Administration. However, it criticizing sharply against the chaebol policies of Roh MooHyun Administration. The JoongangIlbo, known as a pro-chaebol paper, appears anti-government position through the entire four administrations in terms of chaebol policies. Particularly, it reveals hostile editorial coverage during the Roh MooHyun Administration. However, KyunghyangShinmun, currently known as a liberal paper, viewed somewhat complicated positions (see text in more detail) because of its ownership turbulence during the past twenty years. On the other hand, Hangyoreh, regarded as a progressive paper, keeps in supportive attitude consistently against the four sampled administrations as far as regulating each government policies for chaebols.

Ectopic eruption and impaction of canines is a frequently encountered clinical problems. The incidence of impaction ranges between 1-3%. The cause of canine impaction can be the result of localized factors or can be a polygenic multifactorial inheritance and associated with other dental anomalies. The general dentist and pediatric dentist should know how to properly diagnose and manage potential disturbances in the eruption of maxillary canine. Diagnosis of impacted canine at age 8-10 years can significantly reduce serious ramifications, including surgical exposure and orthodontic traction as well as root resorption of the lateral incisors. Extraction of primary canine would be one of the method to prevent the impaction. The surgical procedure should be designed to minimize the destruction of periodontal tissue of impacted canine. Closed eruption technique is thought to be optimal method of surgical exposure compared with other methods. An overview of the incidence, sequela as well as the surgical periodontal, and orthodontic consideration in the management of impacted canine was presented.

Purpose: We retrospectively studied the outcomes of the shoulder impingement syndrome for the treatment of the ultrasound-guided subacromial bursal steroid injection. Materials and Methods: Sixty-six shoulders of sixty-two patients with shoulder impingement syndrome treated from March, 2006 to April, 2009 were involved in this study. All cases underwent standardized, nonoperative treatment protocol consisting of 5~12 MHz high resolution ultrasound-guided local steroid injection into the subacromial bursa in modified Crass position. The shoulder range of motion, VAS score and impingement signs were evaluated during the initial and 1year visits. After injection, shoulder elevation exercise was encouraged. Statistical analysis with ANOVA model and Tukey's post-hoc test with the significance level at 5% were performed using SAS program. Results: All cases showed improved range of motion without limitation of shoulder function at immediate post-injection, 6-week, 3-month and 1year visits. The average VAS score at one year follow-up decreased to 2.85 from 6.47 before injection. In all cases the impingement signs became negative immediate after injection. However, 6 cases showed positive impingement signs after 6-week, which became negative after reinjection. The range of motion and VAS score were improved at one-year follow-up compared to initial visit (p<0.0001). No complication was noted at all follow-up period. Conclusion: Ultrasound-guided subacromial steroid injection alleviated the need of surgery, because it was successful in all our cases to improve pain and function of the shoulders until one year follow-up period.

Purpose: The purpose of this article is to identify and understand the complications of RTSA and to review the current methods of preventing and treating this malady. Materials and Methods: Previous constrained prostheses (ball-and-socket or reverse ball-and-socket designs) have failed because their center of rotation remained lateral to the scapula, which has limited of the motion of the prostheses and produced excessive torque on the glenoid component, and this leads to early loosening. The Grammont reverse prosthesis imposes a new biomechanical environment for the deltoid muscle to act, thus allowing it to compensate for the deficient rotator cuff muscles. Results: The clinical experience does live up to the lofty biomechanical concept and expectations: the reverse prosthesis restores active elevation above $90^{\circ}$ in patients with a cuff-deficient shoulder. However, external rotation often remains limited and particularly in patients with an absent or fat-infiltrated teres minor. Internal rotation is also rarely restored after a reverse prosthesis. Failure to restore sufficient tension in the deltoid may result in prosthetic instability. Conclusion: Finally, surgeons must be aware that the results are less predictable and the complication/revision rates are higher in revision surgery than that in the first surgery. A standardized monitoring tool that has clear definitions and assessment instructions is surely needed to document and then prevent complications after revision surgery.

Purpose: To evaluate the usefulness of arthroscopic repair that was related with full thickness rotator cuff tear and assess clinical result. Materials and Methods: Twenty-one cases of arthroscopically repaired full thickness tear of rotator cuffs were studied. Between October 1998 to July 2002 we have analysed 21 repairs of FTRCT the average age 54(42∼74) years old, mean follow-up was 24(12∼41) months We analyzed the results statistically by paired t-test. Results: Postoperative VAS of pain improved average 7.2 to 1.9, UCLA score improved 13.9 to 31.9, ADL improved 11.5 to 25.5 respectively(all, p<0.001). Eighty-seventh ％ of the patients showed excellent St good results at the final follow-up. The satisfied rate was 90.5%(19cases). Conclusions: Arthroscopic repair in full thickness rotator cuff tear is effective surgical methods.

Purpose: To evaluate the results from arthroscopic repair versus debridement for full-thickness tears of the upper subscapularis tendon. Materials and Methods: Ninety-nine patient outcomes were evaluated and compared prospectively. Sixty-nine patients with full-thickness tears of the upper subscapularis tendon underwent arthroscopic repair (group I) and thirty patients underwent simple debridement (group II) between May 2003 and October 2007. In all patients, the tear was localized to the superior one third of the upper subscapularis tendon. The results of the treatment were assessed by evaluating the UCLA, ASES, and VAS for pain and internal rotation strength scores before and after the operation. Results: In groups I and II, UCLA, ASES, VAS, and internal rotation muscle power (perfect score = 5) scores were improved after surgery. In comparing group I and group II, the UCLA and VAS scores were not significantly different (p>0.05), while the ASES and internal rotation strength scores were significantly different (p<0.05). Conclusion: The arthroscopic repair of full-thickness tears of the upper subscapularis tendon was a better surgical method than simple debridement.
