Because of cultural similarity and geographical proximity, human and material exchanges have been actively conducted between the Korean Peninsula and the Chinese continent since ancient times. During the modern era, these exchanges between the two regions were further expanded due to changes in international relations, the arrangement of transportation routes, and the development of industries. However, exchanges between the Korean Peninsula and the Chinese continent during the modern era were not limited to the expansion of its scale. In the case of Chinese migrant workers(华工), the subject of this study, there was a big difference in the purpose and nature of migration compared to before modern times. The migration of these Chinese workers, which was carried out for economic purposes, began in the late 19th century. They provided necessary labor to Japan and the Korean, where demand for labor was soaring after World War I. This migration of Chinese workers to colonial Joseon left a clear historical mark on both the Korean Peninsula and the Chinese continent. As the rapidly increasing Chinese population in the 1920s, research on them has also been actively conducted at that time. In particular, their population size and characteristics of migration have been analyzed in several studies. Most of these studies estimate the population of Chinese people using ‘The Statistical Yearbook of the Japanese Government-General of Korea(朝鲜总督府统计年报)’, which is the basic data for Japanese colonial rule. However, ‘the statistical yearbook’ was inappropriate to estimate the population of highly mobile Chinese, especially Chinese workers who accounted for the majority of migrants at that time, due to problems with the survey method and survey timing. Therefore, in this study, ‘The national census(国势调查)’ conducted under the concept of the census from 1925 was discovered and demographics of the Chinese population were conducted. This analysis of population data is meaningful as basic data that is important not only for understanding the Chinese migration, but also for the analysis of migration routes and the results of migration. In future studies, plan to conduct a comprehensive analysis of East Asian labor migration in the 1920s using these population data.

한상협,이진원,한정희,김해성,류병윤 대한내시경복강경외과학회 2012 Journal of Minimally Invasive Surgery Vol.15 No.4

Purpose: Laparoscopic appendectomy isused as a three port technique for appendectomy. In children, single port laparoscopic appendectomy is difficult because they have a small peritoneal cavity for manipulation of laparoscopic instruments. We performed transumbilical laparoscopic assisted single port appendectomy (hybrid appendectomy) in children. Methods: From March 2010 to July 2012, we performed transumbilical laparoscopic assisted single port appendectomy in 53 children. We made a vertical incision to the umbilicus approximately 1.5 cm, and a wound retractor (Applied Medical Resources Co., Ltd., Rancho Santa Margarita) was placed in the umbilical incision, and appendix exteriorized the extraperitoneum through the wound retractor. Appendectomy was performed conventionally. We had no conversion cases for laparotomy. Results: A total of 53 patients, 29 females and 24 males,with a mean age of 8.5±2.0 years were enrolled in this retrospective study. The mean operative time was 29.4±9.4minutes. There was no occurrence of complication or mortality. BMI was 17.8±4.9 kg/m2. And mean hospital stay was 3.2±1.0days. Conclusion: In children, transumbilical single port laparoscopic appendectomy is technically difficult because they have a small peritoneal cavity. However, transumbilical laparoscopic assisted single port appendectomy (hybrid appendectomy) appearsto be a safe and effective technique for use in children,which allows for achievement of nearly scarless surgery.

수술로 치유된 콩팥동맥자루

한상협,이정훈,김한준,김흥철 대한혈관외과학회 2011 Vascular Specialist International Vol.27 No.3

Renal artery aneurysm is a rare disease that can be found on routine examination. With development of interventional radiology, most cases of renal artery aneurysm had been treated with coil and stents. However,the use of coil and stents has a higher morbidity than surgical treatment and is anatomically restricted. A 62-year-old female had a scheduled visit the hospital to evaluate ongoing hypertension and upper abdominal pain. On computed tomography scan, a small aneurysmal dilatation was detected in the mid-portion of the left renal artery. We tried to correct this problem using radiologic intervention. However, the attempt had to be aborted because of the anatomical complexity of aneurysm location. During the operation, the aneurysmal sac was found to be located between the inferior border of pancreas and the upper border of the renal vein. After resection of the aneurysm, both ends of the artery were anastomosed directly without using any patches. The patient was discharged without any complications related to the operation. Radiologic intervention is now replacing traditional vascular surgery. However, there are limitations in conditions of anatomical difficulty and complexity.

Bi-Directional Multi-Level Converter for an Energy Storage System

한상협,김흥근,차헌녕,전태원,노의철 전력전자학회 2014 JOURNAL OF POWER ELECTRONICS Vol.14 No.3

This paper proposes a 3 kW single-phase bi-directional multi-level converter for energy storage applications. The proposedtopology is based on the H-bridge structure with four switches connected to the DC-link. A simple phase opposition dispositionPWM method that requires only one carrier signal is also suggested. The switching sequence to balance the capacitor voltage isconsidered. The topology can be extended to a nine-level converter or a three-phase system. The operating principle of theproposed converter is verified through a simulation and an experiment.

1920년대 조선화교 노동이주의 배경 : 식민지조선과 중국 동북지역의 노동환경과 임금을 중심으로

한상협 경북대학교 인문학술원 2023 동서인문 Vol.- No.23

1920년대 급증하는 조선화교의 대부분은 산동출신의 노동자였다. 특히, 해당시기 중국인 노동자의 증가는 평안북도를 위시한 조선북부지역에 집중되었다. 이들 중국인 노동자의 이주노선과 관련하여, 조선북부를 산동출신 노동자의 이주 목적지로 설정할 경우, 이주노선 상 중간 경유지인 중국의 동북지역을 주목할 필요가 있다. 중국의 동북지역은 淸末 이래 화북 流民들의 이주가 지속되어 왔던 지역이었다. 산동을 비롯한 화북지역 流民의 대규모 동북이주를 흔히 ‘闖關東’이라 표현하는데, 이러한 동북이주 역시 식민지조선의 조선화교 증가와 마찬가지로 1920년대에 들어 급증하는 양상을 보이고 있다. 이러한 점에 착안하여, 이번 연구에서는 1920년대 산동과 동북, 조선을 일종의 ‘노동이주권역’으로 설정하고, 각 권역 간의 관계를 규명하기 위해, 그간 크게 주목받지 못한 동북과 식민지조선의 노동환경 및 임금에 대한 분석을 진행한다. 이러한 작업은 중국의 동북이주사와 조선화교사를 연결하는 작업의 일환이며, 1920년대 실제 산동출신 유민들이 동북이라는 유서 깊은 이주지 대신 조선북부지역으로 이주한 배경을 밝히는 작업이기도 하다. 분석은 동북과 조선화교의 인구 추이에 대한 비교분석으로 시작한다. 1920년대 동북지역과 식민지조선 모두 중국인의 이주 인구가 급격히 증가하는 추세이긴 하지만, 식민지조선의 중국인 인구는 동북지역 내에서도 大連, 奉天(現: 審陽), 安東(現: 丹東) 등 남만주지역과 유사한 추이를 기록하고 있다. 이에, 이번 연구에서는 남만주와 식민지조선의 인구 추이 이외에도 이주의 성격 및 노동환경, 임금 등에 대한 면밀한 분석을 통해 산동을 출발한 중국인 노동자가 동북지역 대신 조선으로 이주하게 된 배경을 면밀히 분석한다. 이러한 분석을 통해 양 지역 노동시장의 관계를 규명하고, 1920년대 중반 이후 급증하는 노동쟁의와 노동자 간 충돌 등, 노동시장에서 민족 간 갈등의 배경을 살펴보는 것이 이번 연구의 주요 목적이다. In the 1920s, most of the rapidly increasing “Overseas Chinese in Joseon (朝鮮華僑)” were workers from Shandong (中國山東). In particular, the increase in the number of Chinese workers was concentrated in the northern provinces of Joseon, including Pyeonganbuk-do (平安北道). When regarding cases where northern Joseon was the destination of workers migrating from Shangdong, it is necessary to pay attention to Northeast China (中國東北), which was an intermediate point on the migration route. The Northeast was a region where the migration of Chinese people had continued since the end of the Qing Dynasty (清朝). Large-scale migration in Northeast China, including Shandong, was often referred to as " 闖關東,” and this showed a rapid increase in the 1920s. Based on the above evidence, this paper sets Shandong, Northeast China, and Joseon in the 1920s as a type of "labor migration zone” and analyzes the working environment and the wages of Northeast China and Colonial Joseon to establish the relationship between each region, This research is a part of connecting “history of China's northeastern migration (東北移住史)” and “history of Overseas Chinese in Joseon (朝鮮華僑史).” This has significance in revealing the background of the fact that refugees from Shandong migrated to the northern part of Joseon in the 1920s, instead of the historic migration to Northeast China. This paper also provides a comparative analysis of the population trends of Northeast China and Overseas Chinese in Joseon. In the 1920s, both Northeast China and Colonial Joseon showed a rapid increase in the Chinese population. However, the Chinese population of Colonial Joseon showed a similar trend to that of South Manchuria(“南滿州”), especially Da-Lian(大連), Feng-Tian(奉天), and An-Dong(安東). In addition to analyzing population trends in South Manchuria and Colonial Joseon, this paper studies the background of the Chinese workers’ migration through a close analysis of the characteristics of the migration, the working environment, and the wages. By performing these analyses, this research aims to investigate the relationship between the labor markets in the two regions and examine the background of ethnic conflicts in the labor market, such as labor disputes and conflicts between workers, which have soared since the mid-1920s.
