Lee, Gun Sang,Lee, Myung Ki,Kim, Woo Jae,Kim, Ho Sang,Kim, Jeong Ho,Kim, Yun-Suk The Korean Neurosurgical Society 2017 Journal of Korean neurosurgical society Vol.60 No.1

Objective : We assessed the surgical results of bipolar release in 31 adult patients with uncorrected congenital muscular torticollis (CMT) and more than 12 months of follow-up. Methods : Thirty-one patients underwent a bipolar release of the sternocleidomastoid muscle (SCM) and were retrospectively analyzed. The mean follow-up period was 14.9 months (range, 12-30). The mean age at time of surgery was 30.3 years (range, 20-54). Patients were evaluated with a modified Lee's scoring system, cervicomandibular angle (CMA) measurement, and a global satisfaction rating scale using patient self-reporting. Results : The modified Lee's scoring system indicated excellent results in 4 (12.9%) patients, good in 18 (58.1%), and fair in 9 (29.0%) at the last follow-up after surgery. The improvements in neck movement and head tilt were statistically significant (p<0.05). The preoperative mean CMA was $15.4^{\circ}$ (range, 5.4-29.0), which was reduced to a mean of CMA of $6.3^{\circ}$ (range, 0-25) after surgery (p<0.05). The global satisfaction rating scale was 93.7% (range, 90-100). A transient sensory deficit on the ipsilateral lower ear lobe was noted in three cases. No significant permanent complications occurred. Conclusion : Bipolar release of the SCM is a safe and reliable technique for the treatment of CMT in adults.

Sang‑Wook Kim,Hyeon‑Woo Son,Taek‑Kyun Jung,Young‑Bum Chun,Yi‑Hyun Park,Ji‑Woon Lee,Soong‑Keun Hyun 대한금속·재료학회 2019 METALS AND MATERIALS International Vol.25 No.4

The hot deformation behavior of advanced reduced-activation alloy (ARAA) was investigated using hot torsion tests. Thefl ow stress decreased as deformation temperature increased and as strain rate decreased. The fl ow behavior demonstratedthe typical dynamic recrystallization (DRX). Based on the constitutive analysis of peak stress, the activation energy for hotdeformation was found to be 330.3 kJ mol −1 . Peak stress was analyzed as a function of the Zener–Hollomon parameter, andcalculated and experimental values were in good agreement. A DRX kinetic model for ARAA was derived with deformationconditions based on the Avrami-type model. It was confi rmed that the volume fraction of dynamically recrystallized grainsincreased as deformation temperature increased and as strain rate decreased. The necklace structure and grain boundarybulging were observed in the deformed microstructure of ARAA. The suggested DRX mechanism for ARAA during hotworking is discontinuous DRX.

Purpose: The assessment of trauma patients in the prehospital setting is difficult, but appropriate field triage is critical to the prognosis of trauma patients. We sought to evaluate the triage given by the emergency medical technicians (EMTs) using the trauma score to patients injured in motor vehicle collisions (MVCs). Methods: From June 2012 to July 2012, questionnaires were distributed to EMTs, who had transported injured patients to the study hospital. Scene records, photos of the damaged vehicle, and ambulance run sheets were used to provide physiologic, physical, and mechanistic information about the MVC. To evaluate the appropriateness of the injury assessment by EMTs, we compared their impressions with the hospital`s final diagnosis within a 3 level triage system comprising both the maximum abbreviated injury scale (MAIS) and the injury severity score (ISS). Kappa (k) was calculated to evaluate the agreement between the triage by EMTs and the triage based on hospital`s final diagnosis. Results: A total of 91 patients were analyzed by 31 EMTs. The percentage of males was 57.1%, the mean age was 44.5, and the mean MAIS and ISS were 2.7 and 16.6 respectively. While EMTs correctly diagnosed patient injuries to the extremities in 35.7%, and to the neck in 32.1%, pelvic injuries were missed in 80.0%. The agreement between the triage by the EMTs and the triage based on the hospital`s final diagnosis was 62.6%(k=0.366) by the MAIS and 50.5%(k=0.234) by the ISS. The kappa value was higher in EMT-I than in EMT-II. Conclusion: In MVC, the assessment of injured patients by EMT-I was more appropriate, and the 3-level triage method based on the MAIS could contribute to a more accurate triage. Prospective studies to search for appropriate methods of field triage are required for programming practical education for EMTs.

국립중앙박물과 소장 『조선지도』의 지도사적 의의

This article is about the cartohistorical value and significance of the 『Joseon-jido. 朝鮮地圖, Map of Korea』, the copy of the 『Dongguk-daejeondo, 東國大全圖 Great map of Korea.』 by Jeong Sang-Gi(鄭尙驥), which is the collection of the National Museum of Korea. The conclusions are as follows. First, by the contents of the map, it is presumed that the map was made between the years 1757-1767. Therefore, it is easy to assume that the map was made in 1740s. Among the others, the map was made in the earliest days. Second, the 『Joseon-jido』 was drawn on the fine silk with the delicate lines, and the map has rvtanchuria of China and Japan, which were presumed to be included in the original map. Also, comparing the copies of 『Paldo-bundo, 八道分圖 Maps of Eight Provinces』 by Jeong to the map by trigonometry calculation, we can presume that both of the map were made by the same scale. By these reasons, the 『Joseon-jido』 is presumed to be the Dongguk-daejeondo in 『YoungJo Sillok, Annals ofKing YoungJo』, which Jeong Hang-Ryung(鄭恒齡). son of Jeong Sang-Gi(鄭尙驥). brought from home and copied it to provide the map to the HongMoonKwan(弘文館, Office of Special Advisers) in 1957(33th year of King YoungJo) Third, there are over 2200 place names mentioned in the 『Joseon-jido』, and these names are also mentioned in the Dongguk-daejeondo and the Paldo-bundo. Most of the place names of the natural features were that of the mountains. and the name of the hills were mentioned in detail. Most of the place names of the civil features were that of the military facilities, such as military camps and the mountain castles. Therefore. it can be said that the map had administrative and military purpose. Fourth, the expression of the landscape followed the classic mountain range-centered understanding while at the same time stressing the six Jeongmaks(正脈, Secondary Mountain Range), the important military defence line. The traffic route was expressed in detail among the other civil features, and the mountain castles. military camps and the signal fire were also expressed in detail with the more symbolized marks. Fifth, unlike the existed articles. the map expressed the changes in the military camps, mountain castles, traffic routes, stations and the signal fires.

In 2007, a Taiwanese mathematics historian Wann-Sheng HORNG made a visit to Kyujanggak(the royal library of Joseon Dynasty) in Seoul, Korea. During this visit, he found the Korean math book An abridged version of the Joseon Mathematics (<數學節要>, Su-Hak-Jeol-Yo), which was written by Jong-Hwa AN(9 Nov 1860-24 Nov 1924) in 1882. Then he mentioned the possible importance of AN`s book in his article in the Journal Kyujanggak(vol. 32, June 2008). Jong-Hwa AN is a Korean scholar, activist of patriotism and enlightenment in the latter era of Joseon Dynasty. He passed the last examination of Joseon Dynasty to become a high government officer in 1894. The father of the modern mathematics education in Korea, Sang-Seol LEE(1870-1917) also passed the same examination with him. It is interesting that government high officer AN and LEE both wrote mathematics books in 19th century. In this talk, we now analyze this mathematics book of Joseon written in 1882.

This article examine the relation between Korea’s division system and the films of Shin Sang-ok, who was one of very famous Korean film directors in the golden age of Korean cinemas. Shin Sang-ok has been maybe the only Korean director, who produced his films in two Koreas. Before he was kidnapped by North Korean kidnap gangs, he was an outstanding film director in South Korea, who produced several popular films, as like 〈A Romance Papa〉, 〈King Yeonsan〉, 〈the evergreen tree〉, 〈a guest and mother)〉, 〈the Red muffler〉, and so on. Also, He managed the biggest film company ‘Shin Film’ and the biggest film studio ‘Anyang Film Studio’ in South Korea in 1960s, he maintained to good relation with the president Park Chung-hee’s government at that time. However, as Shin criticized the film policy of Park Chung-hee’s government, especially the problem of film censorship, the conflicts between them went to worse way in 1970’s. And then Shin was kidnapped with his ex-wife a famous Korean film actress Choi Eun-hee to North Korea. Shin abd Choi stayed in there during the 8 years and produced 7 films in North Korea’s Monolithic Ideal Logical System by Kim Jung-il’s enforcement and immense supports. At that time, Shin produced several remarkable films in North Korea, as like 〈not returned the emissary〉, 〈the salt〉, 〈a story of the escape〉. Finally, Shin and Choi escaped from North Korea for obtaining the freedom to the Western world. Two Koreas’s division system brought the restriction of creative film making to a film director Shin Sang-ok.

Daehoji Samil Movement was a large scale Manse{Hurrah]demonstration in which about 1,000 people participated. This demonstration was thoroughly prepared by the townspeople living at Daehoji, and they staged a Manse demonstration marching to Cheonui marketplace at Jeonngmi-myeon on April 4, using Oiljang[market held every five days]. Such data that can prove the Samil Movement at Daehoji is mostly from the imperialist Japan and this research look into these data centering on telegrams, reports, written judgements, one's personal records collected at the Seodemun Prison. There are some cases where the contents of the imperialist Japan's telegrams transmitted at the time of a demonstration are different from those of the reports written up after a demonstration and also the statistics about a demonstration vary according to reporting agencies and a point of time. However, the imperialist Japan oppressed a demonstration by force of arms immediately after it happened by dispatching 8 police officers and 5 guards, arresting 21 participants in the demonstration until the 6th day, or two days after the demonstration. In addition, this research could make certain of the imperialist Japan's harsh suppression on the basis of the fact that on April 8 demonstration, where only 70 people from Jokeum-ri, and 80 people from Songjeon-ri rose against the imperialist Japan, they perpetrated firing guns at the demonstrators, causing patriotic deaths on the spot. There still remain written judgments for those who were indicted for participating in the demonstration while staging a court struggle, and personal records for those at the Seodaemun Prison where they were imprisoned. Through the written judgment for Min, ]ae-bong which was newly discovered, this research could find out new facts on the preparatory process for the demonstration centering on the Daehoji-myeon office. In addition, through the personal records for Lee, In-jeong, Nam, Sung-wu, Kim, Yang-chil, and Song, Jae-man who were imprisoned at the Seodaemun Prison, this research looked into the date for the court decision, releas from prison, and the beginning of sentence execution, etc.
