Objective: The purpose of this study was to provide technical information about the management of occupational exposure limits(OELs) for substances with completely revised ACGIH TLVs. Methods: The history of ACGIH TLVs for aluminum compounds, the reason for the complete revision of the related ACGIH TLV in 2008, and OELs for them in respective countries were reviewed. In addition, the results of a 2019 work environment assessment for aluminum compounds in Korea were reviewed. Results: In 1979, the ACGIH set up the TLVs for aluminum compounds considering types of compounds such as metal dust, pyro powders, welding fumes, soluble salts, alkyls, and aluminum oxide. However, in 2008 the ACGIH withdrew the TLVs for all types of aluminum and its compounds and adopted new TLVs for aluminum metal and insoluble compounds. This can cause confusion in many countries in the management of exposure to aluminum compounds because they adopt or refer to the ACGIH TLVs. Conclusion: Although Korea is setting occupational exposure limits by referring to the ACGIH's TLVs, it is necessary to sufficiently review whether it is necessary to accept the TLVs as they are if a TLV is completely changed, like took place with the revision of aluminum compounds in 2008.

본고는 "초조대장경(初雕大藏經)"판각(板刻)이 완료된 이후 다시 교정(校正)을 하여 보각(補刻)한 흔적(痕迹)을 "초조대장경(初雕大藏經)" 화엄경(華嚴經)(주본(周本)) 권(卷)60에서 찾아내어 분석한 것이다. 문제의 교정 흔적은 "건립지혜당(建立智慧幢) 견고불동요(堅固不動搖) '지(知)'천변화법(天變化法) 이현변화사(而現變化事)"의 내용 가운데 '지(知)'자(字)에서 발견되었다. 분석 결과 문제의 '지(知)'자(字)는 여타의 문자보다 상당히 크고 묵색(墨色) 또한 다른 글자보다 매우 진했다. 이 현상에 의거해서 필자는 이 '지(知)'자(字)는 "초조대장경(初雕大藏經)"의 판각(板刻)이 완료(完了)된 이후 다시 교정(校正)되어 보각(補刻)되었던 것으로 판단하였다 이것은 "초조대장경(初雕大藏經)"의 교정이 상당히 완벽했음을 입증해 주는 하나의 단서가 되는 것이다.

Many clinicians expect complete healing after the removal of temporary anchorage devices, but clinical examination may reveal scar-like tissue. This report presents the typical features of scarring detected after the removal of miniscrews, and the clinical outcome of scar revision along with its pathologic features.

The surgical approach for humeral implant failure can be challenging due to neurovascular anatomy and the possible necessity of osteosynthesis removal. We present a rare case of humeral nail bending after secondary trauma in a patient with preexistent nonunion of the humerus after intramedullary nailing. During revision surgery, the nail was sawed in half and the distal part was removed, followed by plate osteosynthesis with cable fixation to achieve absolute stability. The patient regained a full range of motion 1 year after surgery, and complete healing of the fracture was seen on imaging.

이 연구는 2011년 제정된 고등교육법일부법률개정안(이하 강사법)에 대한 강사들의 인식을 분석하고 향후 이 법의 개정 방향에 대한 쟁점을 논의하기 위해 수행되었다. 이 연구에서는 두 가지 연구문제를 설정하였다. 첫째, 강사법 제정과 강사법의 주요 내용에 대해 강사들은 어떻게 인식하고 있는가? 둘째, 강사법 유예과정에서 정부와 강사노조가 제안한 강사법 개정(안) 및 강사법 개정 방향에 대해 강사들은 어떻게 인식하는가? 이를 위해, 연구자는 강사 및 고등교육 전문가 16명과 심층면담을 실시하였다. 연구결과, 강사들은 강사법 제정 및 도입 의의를 인정하면서도 정부의 생색내기 또는 선거용 입법으로 인식하였으며, 강사법 시행이 반쪽짜리 교원을 양성할 것으로 우려하였다. 또한 이들은 강사법이 강사들의 처우를 실질적으로 개선하는 방향, 예컨대 강사료 인상과 고용 안정화를 보장할 수 있도록 보완되어야 한다고 강조했다. 그러나 강사들의 연령과 전공영역에 따라 강사법 개정 방향에 대한 입장이 나뉘기도 했다. 분석결과를 토대로, 연구자는 강사법 대체법안 마련을 고등교육 재정 확보, 강사노조 또는 개별 강사들 간의 입장 차이, 한국 고등교육의 문제점 응축 등의 쟁점과 관련하여 논의하고 강사들의 처우 개선을 위한 몇 가지 방안을 제안하였다.

The purpose of this study is to investigate the problems concerning 780 music division of DDC. The object is especially arrangement of 780 music in the 20th edition of DDC which is the complete revision. The result is summarized as follows : 1. Although music is an important subject in humanities, especially in arts, it was classified as one division (780) not class. 2. The arrangement of 780 music is severely west-oriented music theory, vocal music and instrumental music. 3. Classification number of 780 music becomes longer because of the limitation of decimal notation. 4. 780 music division of DDC neglects music theory and emphasizes music practicing, especially performance. 5. The assignment of classification number is unbalanced, especially between theory and practice, composition and performance, and among sub-sections of vocal and instrumental music. 6. Many important subject are omitted in DDC music schedule, for example, musicology and branches of musicology, composition and traditional instruments of many countries. 7. Employment of terminology is often improper and inconsistant.

Many urban-plan facilities were settled by the government in the need of infrastructure due to the rapid urbanization. The Constitutional Court judged that the exclusion of land-owners' private right to use their land did not accord with the Constitution, and the infringement of their right because of currently unexecuted facilities became the urgent task to be solved due to the revision of the Urban plan law revised on January 28, 2000. Accordingly, the government needed to establish a complete plan to review and rearrange the long-term unexcuted urban plan facilities. For this plan to be successful, we have constructed the database of unexecuted urban plan facilities by using GIS analysis technique in this research. Further, we will construct a basic database to manage the unexecuted urban plan facilities by utilizing the database we have constructed, computerized geographical information files of LMIS, urban plan facilities data of UPIS, and other information.

This study took a cross-sectional, quantitative approach and profiled EFL students' awareness of the writing process and of teacher feedback. The subjects were 113 college students aged 19-26 years from non-English majors, who were enrolled in three sections of a required English course. According to the scores gained from the essay writing assignment, they were divided into two groups (proficient and less-proficient writers) and responded to an in-class survey. Major findings were that: (1) the vast majority of both groups did not find English writing enjoyable; (2) longer comments gave rise to substantial changes to the students' revisions; (3) the less-proficient writers were shown to benefit from revision significantly more than the proficient writers; (4) Both groups of writers utilized multiple strategies to process teacher feedback and preferred to receive teacher comments using complete sentences rather than phrases or single words; and (5) teacher's marks on grammar and vocabulary claimed to be most conducive to EFL writing development. Several important implications for EFL writing instruction and for future studies are suggested.

Periprosthetic fracture after total elbow replacement surgery is a difficult complication to manage, especially when it comes together with implant loosening. If stem revision and internal fixation of the periprosthetic fracture are performed simultaneously, this would be a very challenging procedure. Most of total elbow replacement implants are cemented type. Cement usage at periprosthetic fracture site may interfere healing of fractured site. Authors underwent internal fixation with use of locking plate and cerclage wire for periprosthetic fracture, allogenous fibular strut bone inserted into the humerus intramedullary canal allowing the fractured site to be more stable without cement usage. At 10-month follow-up, the complete union and good clinical outcome was achieved. We present a novel technique for treating periprosthetic fracture with implant loosening after total elbow replacement surgery, using intramedullary allogenous fibula strut bone graft.
