도로공사 공정계획을 위한 공정 로직 및 건설장비 효율화 방안

송호정,최재현,Song, Hojeong,Choi, Jaehyun 한국건설관리학회 2014 한국건설관리학회 논문집 Vol.15 No.6

도로공사는 선형적이고 반복적인 공사로 공사의 특성상 건설장비에 대한 의존도가 높기 때문에, 건설장비의 효율적 운용에 의한 생산성 향상 및 공사비 절감 효과가 크다. 또한, 도로공사는 시공순서, 현장상황, 적용 공법에 따라 다양한 건설 장비의 선택이 가능하기 때문에 공정계획 시, 공종 간 연계에 따른 세부 작업 및 공법을 고려하여야 한다. 시공자는 현장조건에 맞는 작업을 선택하고 투입될 장비의 종류 및 성능, 수량 등을 사전에 파악하여, 적절한 건설장비 운용계획의 수립을 통한 경제성 향상 방안을 마련해야 한다. 하지만 한정된 유사 공사의 실적정보 및 체계적인 공사계획 방법의 부재로, 적정한 공정계획 수립이 용이하지 않으며, 공법 및 건설장비의 선정에 있어 대부분 경험과 직관에 의존한 공사를 수행하고 있다. 그 결과 시공 이전 공정계획단계에서 수립된 계획은 실행단계에서의 충분한 타당성을 확보하지 못하여 그 활용도가 제한적이다. 본 연구는 일반적인 도로공사의 초기 공정계획 수립단계에서 적용가능한 주요 공종별 공정로직을 개발하고, 공종 별 세부 시공절차 분석을 통하여 현장상황 및 공종에 적용 가능한 건설장비 운용 방안을 제시하였다. 또한 공정로직에 따른 다양한 건설장비 대안들을 대상으로 프로세스 시뮬레이션을 활용하여 경제성 기반의 최적화 장비조합 방안을 개발하였다. 개발된 방법을 이용하여, 계획단계에서의 수립된 다양한 공정계획에 대해 효율성을 평가하고 최적의 자원 선정을 위한 의사결정에 도움을 줄 것으로 판단된다. Highway construction is a combination of linear, repetitive, and highly equipment intensive operations. Various types of construction equipment are deployed to ensure undisrupted performance of construction, and thus productivity improvement and cost-saving can be achieved through well-thought-out planning. The selection of construction equipment is dependent upon construction sequence, site conditions, and construction methods. In the process of planning, management should consider various types of construction methods per each type of construction operation. Also, management should map out proper construction equipment operation plan that takes the construction duration and cost measures into consideration. However, limited availability of historic data from the similar types of operations has been a stumbling block to proper construction planning, making the operations performed based upon experience and intuition guided by rules-of-thumb. As a consequence, the planing phase rarely provided an adequate validity in the implementation phase. The researchers developed a process logic for each construction type that management can utilize from early phase of highway construction planning process. Moreover, derived the construction equipment combination optimized for efficiency by using the process simulation technique. The developed method is expected to be useful for the decision-making process that aims to evaluate efficiency of various process plans and to ensure optimal selection of construction equipment for highway construction projects.

회로 분할을 위한 어댑티드 유전자 알고리즘 연구

송호정(Ho-Jeong Song),김현기(Hyun-Gi Kim) 한국콘텐츠학회 2021 한국콘텐츠학회논문지 Vol.21 No.7

VLSI 설계에서의 분할(partitioning)은 기능의 최적화를 위하여 설계하고자 하는 회로의 그룹화(grouping)하는 단계로서 레이아웃(layout)에서 면적과 전파지연의 최소화를 위해 함께 배치할 소자를 결정하는 문제이다. 이러한 분할 문제에서 해를 얻기 위해 사용되는 알고리즘은 Kernighan-Lin 알고리즘, Fiduccia Mattheyses heuristic, 시뮬레이티드 어닐링, 유전자 알고리즘 등의 방식이 이용된다. 본 논문에서는 회로 분할 문제에 대하여 유전자 알고리즘과 확률 진화 알고리즘을 결합한 어댑티드 유전자 알고리즘을 이용한 해 공간 탐색(solution space search) 방식을 제안하였으며, 제안한 방식을 유전자 알고리즘 및 시뮬레이티드 어닐링 방식과 비교, 분석하였고, 어댑티드 유전자 알고리즘이 시뮬레이티드 어닐링 및 유전자 알고리즘보다 더 효과적으로 최적해에 근접하는 것을 알 수 있었다. In VLSI design, partitioning is a task of clustering objects into groups so that a given objective circuit is optimized. It is used at the layout level to find strongly connected components that can be placed together in order to minimize the layout area and propagation delay. The most popular algorithms for partitioning include the Kernighan-Lin algorithm, Fiduccia-Mattheyses heuristic and simulated annealing. In this paper, we propose a adapted genetic algorithm searching solution space for the circuit partitioning problem, and then compare it with simulated annealing and genetic algorithm by analyzing the results of implementation. As a result, it was found that an adaptive genetic algorithm approaches the optimal solution more effectively than the simulated annealing and genetic algorithm.

최근 한국상고사 논쟁의 본질과 그 대응

송호정(Song, Ho-jung) 한국역사연구회 2016 역사와 현실 Vol.- No.100

Recently, some quasi historians have grouped and argued that Gojoseon and Nakrang-gun were positioned in the Manju area and not inside the Korean peninsula. Debates over the matter span out of control, and eventually became a controversy. Their arguments are old, as those theories had already been thrown in the 1980s, and then resurfaced nowadays, virtually unchanged. Their denouncement and attacks upon legitimate previous studies have finally crossed the line, and should no longer be tolerated. They criticise previous studies for being supposedly ‘similar’ to recent Chinese studies or ‘colonial history’ that had been developed by the Japanese over a century ago. But they do so without presenting sufficient analysis or objective evaluation. It is most troubling that these quasi historians’ arguments, and the possibility that their studies might be used by whoever in political power, could irrevocably compromise the integrity of future historical studies, which would require careful interpretation of historical texts. Historians and researchers can no longer afford to sit back and watch. They should rise and aid in the education of the public. Presented in this article is a critical analysis of quasi historical studies, in which the so-called ‘bases’ of their arguments are carefully examined. This is meant as a comprehensive review of the Korean ancient history controversy which would hopefully remind all of us that these studies, and sometimes other studies in the past as well, oftentimes feature highly politicized chauvinist perspectives, especially when dealing with issues such as territorial boundaries and centers, and do not bother to determine how people actually lived during those times.

고조선 중심지의 위치 문제에 대한 쟁점과 과제

송호정(Song, Ho-jung) 한국역사연구회 2015 역사와 현실 Vol.- No.98

The most important thing that should be considered in Go-Joseon studies is the possibility that the territory of Go-Joseon could have shifted as time went on, that the feature of the Go-Joseon realm could have had different shapes in different periods. The history of Go-Joseon shows two phases: the Bronze culture era when the Go-Joseon people still used Bipa-shaped bronze daggers, and the Iron culture era when Go-Joseon achieved the status of a ‘State.’ From this, we can easily see the importance of acknowledging the fact that there should have been ‘periodic changes’ in the Go-Joseon realm, when we try to approach its history from an academic viewpoint. In the early phases of the Ancient period, borderlines were not that distinctive as they are today. Between states and political entities, incredibly large areas remained unpopulated. Go-Joseon’s western border area in particular is believed to have been more than fluid. And there were various tribes living in the vicinity. So, trying to dictate the Daedong-gang river area as the (Western) border of Go-Joseon, or arguing that Go-Joseon’s realm engulfed the entire Manchu region as well as the Northern part of the Korean peninsula, the “entire time” from beginning to end, is simply unrealistic. Scholars and the public should refrain from considering ‘regional deployment of tribes’ or the ‘range of [their] cultural influences’ as indicators of parameters for an actual political territory. Perceiving the entire realm that shared the Bipa-shaped bronze dagger culture directly as the political territory of Go-Joseon is nothing but an academically inappropriate misconception. The Daedong-gang river in the Pyeong’yang region should not be excluded from the early-stage realm of Go-Joseon, while including not only the Liaodung(遼東) region but also the Liaoshi(遼西) region in Go-Joseon’s supposed realm of influence is simply without sufficient empirical basis.

衛滿朝鮮의 王儉城 위치에 대한 최근 논의와 비판적 검토

송호정(Song, Ho-jung) 호서사학회 2019 역사와 담론 Vol.0 No.92

『史記』 朝鮮列傳의 기록에 따르면 기원전 4세기~기원전 3세기에 燕은 眞番과 朝鮮을 공략하고 鄣塞를 쌓았다. 그리고 기원전 2세기경 燕 지역에서 나온 衛滿은 遼東故塞를 지나 浿水를 건넜다고 한다. 따라서 王儉城의 위치와 관련해 遼東故塞와 浿水의 위치 비정이 가장 중요하다. 기원전 4세기~기원전 3세기에 燕은 東胡를 물리치고 造陽(현 하북성 회래현)에서 襄平(현 요양시)에 이르는 지역에 鄣塞를 설치하고, 상곡군 · 어양군 · 우북평군 · 요서군 · 요동군을 설치하였다. 5개 郡 가운데 遼東郡은 襄平에 치소를 두고 18개 縣을 관리하였다. 이때 요동반도에 위치한 遼東郡 지역에 설치한 장새가 遼東故塞이다. 『사기』 조선열전에 기록된 위만의 남하 기록을 보면, 漢이 등장하여 古朝鮮과 경계로 설정한 浿水는 遼東故塞의 남쪽에 있었다. 漢代에 요동고새 남쪽에서 패수로 비정할 수 있는 강은 압록강과 청천강 두 강이 있었다. 그런데 『漢書』 地理志 등 문헌 기록에는 漢代 遼東 남쪽의 鴨綠江이 浿水가 아닌 鹽難水 또는 馬訾水로 기록되어 있다. 그러므로 古朝鮮과 漢의 경계가 되었던 浿水는 압록강(염난수) 남쪽에 있는 淸川江으로 보는 것이 합리적이다. 遼東古塞를 나와 浿水를 건넌 衛滿은 준왕을 밀어내고 王儉城에서 衛滿朝鮮을 세웠다. 이 기록대로라면 고조선 수도 王儉城은 浿水 남쪽에 있어야 한다. 漢 군대가 고조선을 공격할 때 浿水를 건넌 뒤 洌水 입구에 위치한 王儉城을 포위하였다고 하므로, 洌水는 패수보다 남쪽에 있는 지금의 大同江임이 분명하다. 따라서 후기 고조선의 왕성인 王儉城은 平壤에 있었음이 분명하다. 최근 고고학계를 중심으로 제기된 왕검성 요동설은 고고 자료만으로 논의를 펼친 것이다. 그러나 문헌 자료에서는 遼東 지역 이남에 王儉城이 있었다고 기록하고 있다. 따라서 고고학자들은 이에 대한 대안이나 합리적인 해답을 제시하고 고고학 자료에 입각한 논의를 주장하여야 한다. According to the records of the “Saji(史記)” Joseon dynasty, the Yan (燕) Dynasty attacked Jinbeon and Joseon kingdoms and built a fortress during the 4th century B.C. and 3rd century B.C.. Weiman(衛滿), which came from the Yan area around the 2nd century B.C., crossed the Paishu-river(浿水) by passing the Liaodong old fortress(遼東古塞), indicating that the boundary river of Han and Gojoseon was located on the southern side of the Liaodong old fortress. However, in the literature records such as “Hanshu(漢書)” geographical record, the Yalujiang-river(鴨綠江) is recorded as a Yannanshu-river(鹽難水), not a Paishu-river(浿水). Therefore, it is reasonable to regard the Paishu-river(浿水) that had been the boundary between the Han(漢) and the Gojoseon(古朝鮮) as the Cheongcheonjiang-river(淸川江), south of the Yalujiang-river. Then Wiman(衛滿), who left the Liaodong old fortress(遼東古塞) and crossed the Paishu-river, pushed back the king and built the Wimanjoseon in Wanggeomseong-palace(王儉城). According to this record, the Wanggeomseong-palace, the capital of Gojoseon, should be south of the Paishu-river. It is said that when Han’s army attacked Gojoseon, it crossed the Paishu-river and surrounded the Wanggeomseong-palace, located at the entrance to the Lieshu-river(洌水), so the Lieshu-river must be the Daedongjiang-river(大同江), which lies south of the Paishu-river. Therefore, it is clear that Wanggeomseong-palace was in Pyongyang. The theory of “the Wanggeomseong-palace is located in the Liaodong area,” which was recently suggested by the archaeological community, was discussed only with archaeological data. However, the literature records that the Wanggeomseong-palace was found in the southern region of Liaodong. Therefore, archaeologists should present alternatives or reasonable answers to this and insist on discussions based on archaeological data.

高句麗의 族源과 濊貊

송호정(SONG Ho-jung) 고구려발해학회 2007 고구려발해연구 Vol.27 No.-

'Mac(貊)' that appeared in a number of ancient documents was the name on the tribe resided on the northern side of China. Compared to this, the eastern part of the Palhae Bay was recognized from early times as the residential area of 'The hometown of Yiye(夷濊), for the Ye Tribe. From the Ye Tribe, Joseon became the earliest independent political power, followed by Buyeo, Jinbeon, Imdun and others emerged as independent political power in the region, and 『Sagi(史記)』 collectively called d1e political power and resident group around Joseon as 'yemac(濊貊)'. The name for the northern tribes of China as Mac(貊) combined with 'ye(濊)' after 『Sagi』 to change into the expression on general Ye(濊) Tribe residing on the northeastern part of China. From Yemac that resided around Gojoseon, the pan that was influenced the most northern part became was that Goguryeo around the first century B.C. Yemac of Manchuria that was the land of Gojoseon had certain independence until the second century of B.C., but it eventually became Koguryo. And, from the record of 『Huhanseo(後漢書)』 and 『Samgukji(三國志)』 and others, Koguryo was referred to the same line of 'Mac' or 'Mac Tribe'. In the 3~2 century of B.C., the iron culture was advanced from Liaodong (遼東) to Cheongcheon river(淸川江) and the Korean-style bronze culture was advanced in Western Han area. Dispersion of iron farm tools and equipments brought the advancement of farming technology and increase of its productivity, Furthermore, it would promote the increase of population and the social division that brought birth to the movement of forming new political bodies around Hunjiang(渾江) and middle region of Yalu River(鴨綠江). During the process of such changes, the Koguryo society was established.
