  • This paper analyzes difference between current tunnel ventilation calculation method and advanced one which considers effects of polluted air recirculation near tunnel portals. For the calculation, CFD(Computational fluid dynamics) technique was utilized. From the result, it was found that 4.38% more fresh air is required when there is polluted air recirculation near tunnel portal areas. Hence, it is recommanded that the consideration of polluted air recirculation should be made when deciding the ventilation requirements for tunnel.

  • Major technologic advances in fiberoptic light transmission, video cameras, and instrumentation have allowed great advances in small-joint arthroscopy. Arthroscopy in particular is now well established procedure for accurate diagnosis and operative management of certain ankle disorders. The small size of the ankle and significant periarticular soft tissue structures make placement and advancement of the arthroscope and instrumentation more difficult than in larger joints. Successful arthroscopy of the ankle requires knowledge of the regional anatomy and a familiarity with the available arthroscopic portals. This review article is going to describe the gross and arthroscopic anatomy of the ankle as it relates to current arthroscopic techniques. Particular emphasis is placed on the anatomic relations of the important osseous and soft tissue structures for a safe, reproducible approach to arthroscopic treatment of ankle pathology. Also, current arthroscopic equipment and instruments are included.

  • During the Covid-19 pandemic's first term of April-June 2020, the general public throughout Indonesia became familiar with the slang term "local lockdown." This term emerged in response to disorderly implementation of the half-hearted government policy called Pembatasan Sosial Berskala Besar (PSBB). In villages around the country, people started to build portals to restrict "strangers" or "outsiders" from entering their village areas. These portals were also meant to publicly signal the villagers' fear of the spread of the virus. This paper will discuss two things: first, how fear was produced, using frameworks drawn from Giorgio Agamben's notable works State of Exception and Homo Sacer, and how governance reproduces it; and second, how people come to accept the state of emergency and then publicly express their acceptance of the situation. Critical discourse analysis is applied to read government policy and its reception. The research took place at Rempoah, Kedungmalang, and Pabuwaran villages in Banyumas, the southern regency of Central Java, Indonesia. The villagers' responses to the government's policy are visually represented through written warning signs.

Do People Trust News on Media Overall as Much as They Trust the News They Actually Use? A Study on Credibility of "News I Use" and Credibility of News on Media Overall

  • This study aims to understand how people evaluate the credibility of news they use every day and how such evaluation is related to their credibility assessment of news on media overall. For this purpose, this study examines the relationship between credibility of "news I use" and credibility of news on television and news portals overall, respectively. It also explores whether the relationship is moderated by the strength of political ideology. From regression analyses of a nationwide survey of 5,010 adults in South Korea in 2021, the results showed a lower level of credibility for "news I use" than for overall news on television and portals. The results also revealed a significant relationship between the credibility of "news I use" and credibility of overall news on the two media respectively. The expected moderation effect was significant for portal news, but not for television news. Findings and implications are discussed.

  • Background: The blunted tip of a reusable with multiple uses can cause problems with the passing procedure in arthroscopic Bankart repair. This study assessed the advantage of Scorpion with a $70^{\circ}$ arthroscope in arthroscopic Bankart repair compared to hook typed suture passer. Methods: Scorpion in 19 patients, the hook type suture passer (conventional group) in 18 patients were used. All patients underwent the same procedure except for the type of suture passer used. Another different point of the procedure were telescopes and the number of portals used; three arthroscopic portals (posterior, anterorsuperiorlateral, and mid-anterior) and a $30^{\circ}$ arthroscope in the conventional group, but two portals and a $70^{\circ}$ arthroscope as well as the $30^{\circ}$ one in the Scorpion group. The surgery time and the surgical complications including an iatrogenic axillary nerve injury were recorded. Results: The Scorpion group showed a significant decrease in surgery time compared to the conventional group. In contrast to the conventional group, Scorpion provided an easy estimation of the exit of suture passing, no iatrogenic labral injury during the passing procedure with straight movement and the sharp tip of the knife installed. Iatrogenic supraspinatus injuries could be avoided when making an accessory anteosuperiorlateral portal due to the $70^{\circ}$ arthroscope. Conclusions: In arthroscopic Bankart repair, the use of the Scorpion suture passer and a $70^{\circ}$ arthroscope can reduce the surgery time, avoid unnecessary supraspinatus injury, and avoid iatrogenic axillary nerve damage through the relatively easy and precise suture passing and saving of the anterosuperior portal.

  • This study aims to analyze and evaluate term suggestion services of major search portals, Naver and Google Korea. In particular, this study evaluated relevance and currency of related search terms provided, and analyzed characteristics such as number and distribution of terms, and queries that did not produce terms. This study also analyzed types of terms in terms of the relationship between queries and terms, and investigated types and characteristics of harmful terms and terms with grammatical errors. Finally, Korean queries and English queries, and popular queries and academic queries were compared in terms of the amount and relevance of search terms provided. The results of this study show that the relevance and currency of Naver's related search terms are somewhat higher than those of Google. Both Naver and Google tend to add terms to or delete terms from original queries, and provide identical search terms or synonym terms rather than providing entirely new search terms. The results of this study can be implemented to the portal's effective development of term suggestion services.

  • This study aims to analyze and evaluate video search services of major search portals, Naver and Google Korea. In particular, this study analyzed characteristics such as collection distribution, yearly distribution, the ratio of redundant search results, the ratio of advertising, and the quality of videos. This study also evaluated relevance, credibility, and currency of video search results, and investigated the factors that influence relevance and credibility. Finally, types and characteristics of error results were analyzed. The results of this study show that the relevance of Google's video search results is higher than those of Naver, whereas currency of Naver's search results is somewhat higher than those of Google. Google has more high resolution videos than Naver, and Naver has more advertising than Google. Both Google and Naver return many redundant videos in the search results. The results of this study can be implemented to the portal's effective development of video search services.
