Diagnostic display monitor QA according to AAPM TG18 is usually performed by PACS administrator, product manager and reading doctor, and for acceptance testing and periodic quality control evaluation, a combination of visual and quantitative tests can be used, as outlined in sections 5 and 6 of 'assessment of display performance for medical imaging systems'. Although many display tests can be performed visually, a more objective and quantitative evaluation of display performance requires special test tools. The required instruments vary in their complexity and cost, depending on the context of the evaluation(research, acceptance testing, or quality control) and how thorough the evaluation needs to be. Objective and reliable assessment of many display characteristics can be performed with relatively inexpensive equipment, So, we made 'AAPM TG18 guiding instrument' to ues variable purpose of the evaluation of 'geometrical distortions(quantitative"', 'veiling glare(visual)' and 'sensor calibration'. The spatial measurements for the quantitative evaluation of geometric distortions, and the measurement of the veling-glare ring response function which provides information regarding the spatial extent of the luminance spread, can be performed using the TG18 guiding instrument can be used to sensor calibration to standardize the basic rate of 0% luminance when periodic calibration.

This paper extracted formal characteristics appearing repetitively in Kim Ji Heon's scenario works making a study of them and examined them from the perspective of the aspects of the confrontation between the author' external environments and the world of his creation. This viewpoint comprehensively implies the two aspects of the acceptance of public needs and the creativity his scenarios have in universal characteristics of the film and scenario community where he made his debut as a scenario writer and played activities most actively. In addition, we investigated how literary features are expressed concretely in the world of his works who has been evaluated as a writer with excellent 'literary value.' His scenario world whose base is humanity and existential questions also performs a function as the reading scenario by realizing one literary perfection in itself and poetic description rather than referential function as a film script, which indicates the aspects of values his scenarios have in the existing creation practice focused on story telling, and especially, in the case of "Manchoo-Late fall" it was found that it expanded the areas of literary value through the beauty of modern form. Through this analysis it is seen that the need was exposed to reconsider problematic recognitions that he was not able to be positioned properly as a writer despite the excellent literary values of Kim Ji Heon's scenarios. This study has a meaning as a start in our research climate where the research on Korean scenario writers is not made in an earnest way but it is necessary to keep making more thorough studies including other scenarios which are not organized into the collection of works, and it is also necessary to make a comparative study with cinematized film texts in our view.

This study evaluated and compared the donor site morbidity following minimally invasive and conventional open harvesting of iliac bone for secondary alveolar bone grafting in cleft palate patients. A thorough electronic search of PubMed, Google Scholar, EMBASE, and an institutional library and manual search of various journals was done; Inclusion criteria: 1) full-text articles using a minimally invasive or conventional open harvesting technique for iliac bone for secondary alveolar grafting in cleft palate patients and 2) articles published between January 1, 2001 and June 30, 2017 and Exclusion criteria: 1) articles published in languages other than English, 2) case reports, case series, animal studies, in vitro studies, and letters to the editor, and 3) full-text article unavailable even after writing to the authors. Preliminary screening of 274 studies excluded 223 studies for not meeting the eligibility criteria. Of the remaining 51 studies, 19 were removed for being duplicates. Of the remaining 32 studies, 15 were excluded after reading the abstract. Of the 17 studies that were left, 2 were excluded because they were in a language other than English, and 2 were excluded because the study group did not mention cleft palate patients. Thus, 13 studies providing results for a total of 654 patients were included in this qualitative synthesis. Minimally invasive bone graft harvest techniques are better than the conventional open iliac bone harvest method because they offer shorter operative time, decreased requirement for pain medications, less pain on discharge, and a shorter hospital stay.

The four precious results are beard below after thorough study of Jeoneul(錢乙)'s descended piece and main citation reference from Song(宋) era. 1. Jeoneul(錢乙)'s historical period seems that he finished his life in the age of 82, from Cheonseong(天聖) 10years(Year 1032) to Jeonghwa(政和) 3years(Year 1113) in North Song(北宋) era. However, it also seems that his life terminated Seonhwa(宣和)元年in 1119. The title of "Soayakjeungjikgyeol(小兒藥證直訣)" was reflected in "Sagojeonseo(四庫全書)" as "Soayakjeungjikgyeol(小兒藥證直訣)", however according to various of previous descended references and citations indicate that "Soayakjeungjikgyeol(小兒藥證直訣)" is more appropriate than "Soayakjeungjikgyeol(小兒藥證直訣)". Furthermore, the name, Yeomhyochung(閻孝忠), who edited the reference "Soayakjeungjikgyeol(小兒藥證直訣)" was appeared as Yeomgyechung(閻孝忠) in many different old references. Thus, even though, Sagogoan(四庫館) and Juhakhae(周學海) looked as Yeomgyechung(閻孝忠), but it seems Yeomhyochung(閻孝忠) in "Songsa(宋史)" Yemunji(藝文志) is more authentic than others. 2. When first edition of "Soayakjeungjikgyeol(小兒藥證直訣)" was published, Yeomhyochung(閻孝忠)'s the first book of "Yeomssisoabangnon(閻氏小兒方論)" and the first chapter of Yugi's "Jeonjungyangjeon(錢仲陽傳)" were attached in one book. Not long after of the first edition, Donggeup(董汲)'s first book of "Soabanjinbigeupbangnon(小兒斑疹備急方論)" and Jeoneul(錢乙)'s additional attachment was added in prescription reference. Among these references which were published in Song era, the original copy which Jinsegeol(陳世傑) published in Chung era in Ganghi(康熙) 58years (Year 1719) was remained and the first edition that Yangsugyeong(楊守敬) collected in Japan was published in "(lbonbangseoji(日本訪書志)" called Seonhwabon(宣和本). 3. Ungjonglip(熊宗立)'s "LyujeungjuseokJeonssisoabanggyeol(類證注釋錢氏小兒方訣)", Seolgi(薛己)'s "Gyojeongjeonssisoayakjeungjikgyeol(校正錢氏小兒藥證直訣)" Muyeongjeon-Chuijinbon(武英殿聚珍本) were followed Yangsugyeong(楊守敬)'s called Seonhwabon(宣和本) theory, in addition Yubang(劉昉)'s "Yuyusinseo(幼幼新書)" and "Soayakjeungjikgyeol(小兒藥證直訣)" quoted from Chosun "Euibangyuchui(醫方類聚)" also followed Yangsugyeong(楊守敬)'s called Seonhwabon(宣和本) theory. On the other hand, Jinsegeol(陳世傑)'s Gisudangbon(起秀堂本) and reprinted Juhakhaebon(周學海本) belong to parts of Songbokganbon(宋復刊本). 4. In major references and citation materials descended from "Soayakjeungjikgyeol(小兒藥證直訣)", Yubang(劉昉)'s "Yuyusinseo(幼幼新書)" and "Soauisaengchongaminonbang(小兒衛生總微論方)" were cited in Song era and some related parts in "Yeongnakdaejeon(永樂大典)", "Soayakjeungjikgyeol(小兒藥證直訣)" related sections, Ungjonglip(熊宗立)'s reedited and annotated part of "Lyujeungjuseokjeonssisoabanggyeol(類證注釋錢氏小兒方訣)", Seolgi(薛己)'s proof reading and annotated "Gyojujeonssisoayakjeungjingyeol(校注錢氏小兒藥證直訣)", "Euibangyuchui(醫方類聚)"'s quotation. In Chung(淸)era, Jinsegeol(陳世傑)'s re-published reference, Gisudangbon(起秀堂本), which was simply printed in Song and proof read and republished Juhakhaebon(周學海本), Muyeongjeonchuijinbon(武英殿聚珍本) compiled from "Yeongnakdaejeon(永樂大典)", Yangsugyeong(楊守敬)'s "Jeonssisoayakjeungjikgyeol(錢氏小兒藥證直訣)" mentioned in "Ilbonbangseoji(日本訪書志)", Jangsui's annotation, "Soayakjeungjikgyeoljeonjeong(小兒藥證直訣箋正)" and Simgeumo(沈金鰲)'s "Yuguaseokmi(幼科釋謎)" which was applied Jeoneul(錢乙)'s theory and prescription.

단형질 개체모형을 이용한 육종가 추정프로그램의 해를 구하는 컴퓨터 프로그램을 포트란 언어를 이용하여 자체개발하였고, 프로그램은 자료기반으로 반복적으로 계산을 해 나가는 간접법을 이용한 것으로 일반적인 알고리즘으로 프로그램을 개발하고 이의 효율을 개선한 개선알고리즘으로 프로그램을 개발하여, 두 프로그램 간 효율을 비교하였다. 기존의 전통적인 알고리즘은 순차적인 반복문을 이용하여 자료를 읽고 기록하는 방법이며, 새로운 알고리즘은 효과별로 LHS를 직접 작성하여 추정하는 방법을 사용하였다. 개발된 두 가지 프로그램으로 육종가를 추정하고, 그 추정 값이 정확하게 평가되었는지 알아보기 위하여 기존에 개발되어 사용되고 있는 BLUPF90 (Misztal, 2007)과 MTDFREML (Boldman 등, 1999)과 비교하여 보았다. 서로 다른 프로그램으로 추정된 육종가간의 상관은 전체 항목에서 99% 이상 고도의 상관이 나타났으며, 프로그램 추정치 간의 높은 상관으로 볼 때 Model I, Model II는 정확하게 개발되었고 평가된 것을 확인할 수 있었다. Solution이 수렴 될 때까지의 반복횟수는 Model I은 2,568 round, Model II는 1,038 round로 수렴되어 Model II가 Model I보다 작은 반복횟수에서 수렴이 된 것을 확인할 수 있었으며, 수렴속도는 Model I은 256.008초, Model II는 235.729초로 Model II가 Model I 보다 약 10% 정도 개선된 것을 확인할 수 있었다. 개발된 프로그램을 기존 D/B와 연계한다면 농가 및 지자체 등에 지속적인 개량 정보를 제공할 수 있으며, 농가 단위 암소 유전능력평가로 암소개량을 도모할 수 있을 것이라 사료된다.
