In the construction industry, the construction process is managed based on the completed construction in comparison to the planned construction. With the current construction management system, it is difficult to respond to construction delays in advance, because the construction process rate cannot be estimated quantitatively. In this paper, we developed an AI-based warning system that proactively predicts the delay in construction based on the completed construction of the past and additional data such as budget, subcontractor, and weather data. We experimented on two types of construction sites and seven machine and deep learning models and evaluated the prediction performance of the models for the construction process rate of the future three months with MAE. We analyze the importance of each feature on the model prediction using SHAP values. Furthermore, we select the adequate target variable for construction process prediction based on the results of prediction and key delay factors.

This paper suggests the establishment of construction arbitration tribunal in The Korean Commercial Arbitration Board or the construction arbitration institution under the Ministry of Construction for effective system of Construction Arbitration. Our conclusion tells that it is desirable to establish construction arbitration institution under the Ministry of Construction upon the result of analyzing some factors such as participation of construction workers, sophistication of construction field. In contrast, it is more desirable to establish the construction arbitration tribunal in The Korean Commercial Arbitration Board when we consider the feasibility, sophistication of ADR, organization, rules, arbitrator availability, internationalization Therefore, our final suggestion is to establish construction arbitration tribunal in The Korean Commercial Arbitration Board for effective system of Construction Arbitration. More detailed are as follows: ■ Establishment of the committee for resolution of construction disputes consisting of experts and specialists from construction-related institution, union, law firm and universities. ■ The committee manages finance, rules on construction arbitration and arbitrator members. ■ Establishment of intermediation team, construction arbitration team, housing arbitration team, real estate arbitration team under the construction arbitration tribunal ■ Establishment of a committee of arrangements consisting of experts and specialists from The Korean Association of Arbitration Studies, Korea Arbitrators Association, The Korean Commercial Arbitration Board, The Construction Association of Korea in order to accomplish effective system for construction arbitration.

Construction site layout is attracting attention as efficient use of construction site space greatly affects the duration and cost of the overall construction. Therefore, there are many studies that automate and optimize construction site layout planning. However, the usability of construction site, which consists of goal variables of the studies, has still been unknown. Therefore, the authors present the evaluation criteria for usability of construction site layout and evaluate the usability of domestic construction sites through user survey. Furthermore, the difference in usability between construction site managers and construction site workers was confirmed. As a result of the survey, domestic construction site layout had a low effectiveness and had the lowest score in the environment category. In addition, construction site workers scored lower overall than construction site managers. Through such usability evaluation results, it contributed to the construction site layout theory by assessing current construction site layout practice and suggesting an improvement direction for automating site layout planning.

For this study, a series of interviews with engineers in the Korean construction industry was carried out through a formal workshop format to analyze the causes of the inferior quality of builders’ hardware. The authors established the causes of defects in window hardware construction in relation to the three aspects of system, design, and construction as involving the following seven factors: lack of system (including low ability to create construction specifications); low social awareness of the importance of window hardware; low technical capability to create design drawings; low design costs; small manufacturing capacity; low construction cost; and short duration of construction. Among the seven causes, the biggest cause of defects in window hardware construction is the lack of a system (low ability to create construction specifications), followed by low technical capability to create design drawings. In addition,this study carried out basic research to create measures to prevent defects in window hardware construction by analyzing how such causes of defects are distributed depending on the scale of architectural firms and construction companies during actual projects. 본 연구에서는 창호철물 공사의 하자발생 원인을 제도(System), 설계, 시공 3가지 측면에서 제도 미비(공사시방서 작성능력 부족등), 창호철물의 중요성에 대한 사회적 인식부족, 설계도면 작성 기술력 부족, 설계비 저가등 7가지를 도출하였다. 도출된 7가지 원인 중 창호철물 공사의 하자 발생에 높은 영향을 미치는 원인은 제도 미비(공사시방서 작성능력 부족), 설계도면 작성 기술력 부족이 각각 1순위, 2순위로 나타났다. 또한 이러한 하자발생 원인이 실제프로젝트에서 건축사사무소와 시공사의 규모에 따라 어떻게분포하는지와 시공품질에 미치는 영향을 분석·제시함으로 써 향후 창호철물공사 하자방지 방안 마련을 위한 기초 연구를 수행하였다.

신라 월성 성벽의 구간별 축조 공정과 왕경의 축성 기술

In this article, the construction process was analyzed by dividing Wolseong, a royal castle of Silla, by construction section. By comparing Dodangsan Fortress and Namsan Fortress, it was intended to reveal the construction technology of Silla Wanggyeong. In addition, in order to see if the construction technology of the Wanggyeong Fortress was confirmed in other buildings, the exchange of fortification technology was reviewed by comparing tombs and embankments. Wolseong was analyzed by dividing it into a moat section, a west wall section, and a north wall section, and the preliminary survey of Japanese colonial era and the 2011 excavation survey were used as supplementary data. In view of the section of the west wall and the section of the north wall, it is believed that the built-up wall will be completed after the formation of the base → the central frame → three to four times of extending construction. The basic construction process was the same overall, but the three sections show the construction of the wall using different construction techniques and materials according to the base conditions. In addition, in the moat section and the west wall section, traces of repairs were found two to three times after the wall was built, and the outer wall or inner wall was partially supplemented according to the maintenance situation. As Dodangsan Fortress and Namsan Fortress were built in a way that made hills → built slopes, a different construction technology from Wolseong Fortress was identified. Both fortresses were constructed with a construction method suitable for small-scale earthen fortifications, and as it is estimated to be a political space and a government building, it can be seen that they were efficiently built according to the purpose of construction. On the other hand, although Silla’s stone-mounded wooden chamber was built at the same time, the similarity of fortification technology was captured only in the Hoseok structure, where the functional sector was emphasized, and various construction techniques were shared for each construction process in the embankment.

Construction ability evaluation method is a system in which the Minister of land and transportevaluates and publishes the construction ability of the construction companies at the end of Julyevery year, and reports the indicators, "estimated value of construction ability evaluation." Estimatedvalue of construction ability evaluation is used as an important means of providing information ofthe company in charge of construction when contracting various constructions. This study verifieswhether the estimated value of construction ability evaluation under the revised evaluation methoddiffers statistically significantly from the estimated value of construction ability evaluation under theexisting evaluation method. In addition, based on the study by Kwon Hai-sook, Oh Wonjung(2016), that the estimated value of construction ability evaluation has value relevance, it isrequired to verify that the value relevance to the estimated value of construction ability evaluationhas increased. The empirical analysis results showed that differences exist between the estimated values ofconstruction ability evaluation before and after the revision of the construction capability evaluationmethod, and the relevance of the estimated value of construction ability evaluation increased afterthe revision of the construction capability evaluation method. In addition, it was found that theestimated value of construction performance evaluation, management evaluation, technology abilityevaluation, and new technology evaluation that constitute the estimated values of construction abilityevaluation after the revision of the construction ability evaluation method also became more relevantto the value of the company. The analysis results are interpreted as a result of the revisedconstruction ability assessment method, which means that it can provide information related to theentity's value rather than the existing construction ability evaluation method. 시공능력평가제도는 국토교통부 장관이 매년 7월말 건설업체의 시공실적, 경영상태, 기술능력 및 신인도를 기초로 시공능력을 평가하고 공시하는 제도로서 시공능력평가액이라는 지표를산출하여 보고하고 있다. 시공능력평가액은 각종 공사계약시 공사를 담당하는 기업의 정보를 제공하는 중요한 수단으로 사용되고 있다. 본 연구는 개정된 평가방법에 의한 시공능력평가액이기존 평가방법에 따른 시공능력평가액과 통계적으로 유의한 차이가 있는지를 검증하고 추가로시공능력평가액이 기업가치와 관련이 있다는 권해숙‧오원정(2016)의 연구를 근거해 시공능력평가액의 기업가치관련성이 증가했는지를 검증하고자 한다. 실증분석결과, 시공능력평가제도 개정 전․후의 시공능력평가액 간에 차이가 존재한다는 결과가 나타났고, 시공능력평가제도 개정 이후 시공능력평가액의 기업가치관련성이 증가한 것으로나타났다. 또한 시공능력평가액을 구성하는 공사실적평가액, 경영평가액, 기술능력평가액, 신인도평가액도 시공능력평가제도 개정 이후 기업가치와의 관련성이 더욱 높아지는 것으로 나타났다. 이러한 분석결과는 개정된 시공능력평가제도가 기존의 시공능력평가제도보다 기업가치와관련된 정보를 제공할 수 있다는 것을 의미하는 결과로 해석된다.

현대 중국어 비전형적 이중목적어 구문 고찰 : O1이 장소목적어인 경우를 중심으로

남양우 ( Nam¸ Ryangwoo ) 한국외국어대학교 중국연구소 2021 中國硏究 Vol.88 No.-

Construction grammar claims that a language consists of constructions. In particular, simple clause constructions can be expanded either internally or externally. This paper explores the generative mechanisms and characteristics of ‘place recipient-double object construction’ based on this perspective. This construction was first influenced by the typical double-objective construction. Chinese double objective constructions have high expandability, so it is polysemous, ‘place recipient-double object construction’ also has a polysemous relationship with the double-objective construction. In addition, this construction was influenced by the fugitive construction and ‘possessor-subject possessee-object’ construction, they are connected metaphorically to each other. This paper compared the relevant constructions which are ‘ba’ construction and ‘S+在NP+V+O’ construction to reveal the individual characteristics of the ‘place recipient-double object construction’. ‘place recipient-double object construction’ and ‘ba’ construction can commonly mean ‘movement of a theme from an agent to a place’, but the difference between the two constructions is the information value of O2. In A, the subject argument is of no informational value to the listener because it is an old information. ‘ba’ construction's theme is old information, so it has no informational value to the listener. On the other hand, ‘place recipient-double object construction’'s theme is new information, so it has informational value to the listener. ‘place recipient-double object construction’ and ‘S+在NP+V+O’ construction differ in terms of the prominence of place. In ‘S+在NP+V+O’ construction, a place argument is not profiled and it just functions as ground. On the other hand, a place argument of ‘place recipient-double object construction’ is a remarkable participant profiled as part of the whole process. This reflects the cognitive differences of speakers who perceive the same event differently.

통사적 변이와 구문 형성

이정훈(Chung Hoon Lee) 현대문법학회 2014 현대문법연구 Vol.76 No.-

There are many types of constructions in languages. And two approaches are proposed to explain these constructions. The one is rule-based approach, and the other is non-rule-base approach, for example Construction Grammar. Adopting former approach, this paper proposes that a syntactic variation can be the cause of construction formation. To clarify this idea, constructions are grouped into three types: a normal construction type, a quasi normal construction type, and a non-normal construction type. In these cases, ‘normal’ means ‘rule obeying’ or ‘can be formed by rules’. Furthermore, three Korean constructions, such as verbal reduplication construction, ‘geoss-i-da’ construction, and embedded conjunction construction, are examined to check the main proposal.

구문다의성 및 구문확장에 관한 소고

남양우 ( Nam Ryangwoo ) 한국중국언어학회 2020 중국언어연구 Vol.0 No.89

This paper discussed the construction polysemy and the construction expansion based on previous study about individual constructions. The construction has its construction meaning, which can be extended from central sense to expanded sense. We can explain polysemy of the construction through core meaning and meaning chains, like vocabularies. The construction can also be expanded under the influence of other constructions. The construction expansion can be divided into four types. First type is that two constructions have same form but their arguments are different. Second type is that two constructions have different form but their arguments are same. Third type is that two constructions have different argument but one construction is subpart of the other construction. Forth type is that two constructions have different form and argument, but they are metaphorically involved. Polysemy of some constructions can not be explained by core meaning and meaning chains, these constructions are influenced by expansion of the construction itself and external forces. The construction may be expanded with a complex influence from multiple constructions in the process of expansion. And some constructions have polysemy and construction expansion together. In conclusion, the construction polysemy and the construction expansion show complex aspects in which the constructions continue to develop as they interact with each other.

A Construction Grammar Approach to Korean Double Accusative Construction

Eugene Chung 고려대학교 언어정보연구소 2015 언어정보 Vol.21 No.-

This paper studies Korean double accusative constructions within the frameworks of the Construction Grammar (CxG). We first investigate the syntactic and semantic properties of English double object construction followed by the Korean double accusative examples. Yoon (2015) classifies Korean double accusative construction into six different types based on the characteristics of two noun phrases: double object, inalienable possession, object and accusative marked adverb, object and quantifier/classifier, type-token and modifier-modifiee type. This study adopted Goldberg's construction grammar to analyze Korean double accusative constructions. Goldberg (1995) proposed the central sense of the ditransitive construction is when “the agent successfully causes the recipient to receive the patient.” The verbs Goldberg specifies as arguments to this central sense are verbs of giving, verbs of instantaneous causation and verbs of continuous causation. Because these verb types have substantially different semantics, the central sense needs to be represented into different constructions. Korean double accusative constructions are not limited to the semantic constraints such as transfer of possession. The study shows diverse thematic roles of the arguments are involved in the Korean accusative constructions.
