Si is a genre which has been steadily loved by Korean, Particularly, 1920's through 1930's, the Revival Movement of Sijo is made by the school of Literary for People, including Choi Namseon, Lee Byeonggi and Lee Eunsang. And Kwon Goohyeon, a member of KAPF, and Han Yongwoon, not belonging to any literary group were interested in Sijo. Kwon Goohyeon, both a member of KAPF and an anarchist has published A Present of Black Room(1927), which is one of the two published in 1920's-1920's saw only two volumes of Sijo works be published: Choi Namseon's 108 Agony(1926) and Kwon's. However, Kwon Goohyeon's work has not been illuminated. compared with Choi Namseon's and the Revival Movement Sijo by the school of Literary for People. It is because Korean literary world has been under the anti-communism ideology since the Liberation of Korea. However, it caused to explore proletarianism Sijo (Joh woon) and proletarianism poetry (Park Yeonghee) that Kwon is a memeber of KAPF and an anarchist. Han Yongwoon, not belonging to any literary group, was very famous as the poet of My Belolved One's Silence(1926), not as a Sijo poet. It means that he s not been illuminated as a Sijo poet. However, his Sijo is enough to contain his various features such as a man of Independence Movement, a Buddhist monk, a lyrical poet and so on. His first Sijo is For Planting Mookoonghwa-Poetry Written in Prison(1922), which has been published four years prior to My Beloved One's. And his affection on Sijo is inferred from the fact that he has constantly published Sijo more than free verse. The aim this thesis is to find out a position of Sijo 1920's through 1930's from a study on Kwon Goohyeon's and Han Yongwoon's Sijo. Sijo, Korean traditional literary genre, was written by most of the poets including not only the school of Literary for People but Kwon Goohyeon and Han Yongwoon 1920's through 1930's. As a result, the writing of Sijo was not a partial movement by the anti-KAPF group, but by a paradigm in 1920's through 1930's.

Design-build projects were devised to enhance the design technologies of the domestic construction industry and the efficiency of public works, contributing greatly to the development of construction technologies. However, as various stages of the process, such as formulation of basic plans and design documents, and deliberations proceed, claims, including changes in the requirements of clients, and design changes occur. These claims result in the delay in construction and an increase in construction costs. In this regard, this study attempted to identify main claims that delay construction and increase the costs of design-build projects, prevent claims in the future, and improve the efficiency of project implementation.

In order to reduce fatal accidents, a systematic safety management should be performed at a construction site. A lot of researches on direct causes of fatal accidents and indirect causes which affect the direct causes have been conducted for effective safety management. In the previous studies, these causes are considered separately because of the difficulty of recognition of indirect causes. It is also hard to measure the negative impact of these causes and notice their occurrence the perception of its problem. However, a study on identification of complicated relationship between these two types of causes is necessary since an accident occurs due to the chain reaction that indirect causes trigger the direct causes which lead to the fatal accidents. Therefore, this study proposes a safety management plan that considers indirect and direct causes of fatal accidents cases in the Korean construction industry. Then this paper suggests a plan of safety management by identifying major causes of the accidents.

Construction industry is becoming more advanced, but safety accidents are not decreasing and unsafe act (UA) and human errors (HE) are the main causes of safety accidents. Therefore, this study aims to analyze the relationships between unsafe acts and human errors for construction accident prevents. Specifically, the Correlation Analysis is used to quantify 24 combinations of the relationship between the UA and HE. Then, the Kano Model, and Timko Satisfied Coefficient was utilized to find 6 combinations for construction accident prevention plans. As the result of Timko Satisfied Coefficient, an interview was conducted with three safety managers and 6 safety prevention plan is proposed. Through these results, it is expected that the combination of 24 accidents will be basic data of safety management. Especially, the proposed safety prevention plans considering the characteristics of 6 combinations with high correlation can contribute to prevention of safety accidents at the construction site.

Construction defects are major components that result in cost overruns and schedule delays in construction projects. There have been extensive research efforts to investigate the cause of defects. However, little effort has been devoted to analyze correlation among various reasons of construction defects while a defect is not usually an outcome of a single cause, but rather occurs when several interrelated causes combine. Based on this recognition, this paper analyzes 831 nonconformity reports collected from 30 construction projects in Korea from 2011 to 2014. The correlation analysis revealed that a significant portion of construction defects occurred in the procurement and construction phase and as the pattern of function defect and installation defect. Triggered by human error, defective material and faulty method, these defects are treated by conccession, repair, rework that can significantly lower the cost and schedule performance. This paper is significant in terms of providing a theoretical basis for analyzing correlation among various reasons of construction defects and quantitative measures for establishing effective defect prevention strategies.

Since Korea lunched the 4 Major River Restoration Project, the hydrological regime which is one of the major determinants for riverine condition have actually changed. It also important to connect hydrological characteristics and vegetation. The objective of this study is to investigate the influence of hydrological regime on riverine vegetations and its successions. Iunundated exceedance probability concept are suggested to estimate rehabilitated and succession on the Binae island in the Han River. The result shows that the P=0.08 or lower IEPs should have the disturbance for vegetations, or should be changed to a hydrophilic ones. Therefore, agency which is mainly responsible for river and flow may have to be changed and considered flow regulation standard to conserve riverine zone.

This study examined the characteristics of eel Anguilla japonica sperm using the CASA (computer-assisted sperm analysis) system and attempted to provide the composition for artificial seminal plasma by regulating of inorganic elements. Sperm samples were first divided into four groups based on motility and progressive motility: (A) 0-10%, (B) 10-40%, (C) 40-70%, and (D) 70-100%. For observing sperm velocity variations, VCL, which is curve motion velocity, showed the highest values in all groups. The directional factor, beat cross frequency, was lower in higher activity groups, showing an opposite correlation with sperm activity. The head sizes of spermatozoa in higher activity groups were significantly larger than those in lower activity groups. The Na⁺ and K⁺ ions were important in the inorganic composition of seminal plasma in this species. Furthermore, regulating the composition in artificial seminal plasma improved the formula compared to the existing element, exhibiting 120 mM Na and 30 mM K when the sperm was conserved for a long time and 120 mM NA and 40 mM K when the sperm was conserved for a short time.

In spite of many previous studies conducted to prevent safety accidents at construction sites, the frequency of safety accidents has not decreased. And recently, a lot of research has been done to analyze the causes of the accidents resulting from the personal characteristics and behaviors of managers or workers, and eliminate them. However, despite these efforts, safety accidents occur consistently as managers and workers shift their responsibilities for the safety accidents onto someone other than themselves. Therefore, in order to prevent safety accidents, this study investigated the consciousness of shifting responsibility among managers and workers and analyzed the correlation between factors influencing the consciousness of shifting responsibility. In addition, it proposed the quantitative levels of the consciousness of shifting responsibility based on the survey of managers and workers. The results of this study demonstrated that managers tend to the shift responsibility onto workers, whereas workers the shift responsibility onto managers. It was additionally demonstrated that there is a correlation between the consciousness of shifting responsibility and the factors influencing it. The findings of this study are expected to improve the safety awareness among managers and workers and make contributions in the theoretical and practical aspects of construction safety management.

Construction projects are getting more complex and larger-sized with a high economic growth rate and development of new construction technologies. In addition, interests and demands on standards of construction quality are further increasing. This trend requires more systematic and a higher level of construction quality management. While the government has strengthened the regulations for quality assurance, many quality problems have repeatedly occurred mainly due to lack of recognition for quality management and quality control systems. To address this issue, this paper aims to suggest quality management improvement scheme through analyzing 3,443 nonconforming items identified during inspection of 393 construction sites from March 2012 to October 2014. The quality management improvement scheme suggested in this research is expected to prevent quality problems and defects and thus improve construction performances.

In domestic public construction, disputes are increasing due to differences among stakeholders regarding contract price adjustment. In particular, the actual cost-plus fee for overhead costs due to the schedule extension cannot be agreed upon at the administrative phase, and most of them seek judicial judgment. Thus, this study aims to propose a 'sufficiently satisfactory' alternative to reach an agreement before disputes in order to minimize disputes related to the calculation of additional overhead costs. To this end, this study proposes three alternatives based on the rate method. Firstly, when calculating additional overhead costs, it is not calculated as an actual cost-plus-fee method, but as a rate compared to direct labor costs among net direct costs. Secondly, the calculated indirect labor costs are compensated for up to the legal maximum of legal limit costs such as general management costs, profits and so on. Thirdly, it reflects overhead costs increased or decreased due to change orders. Risks were analyzed by collecting expert opinions on the proposed methods and applying actual cases. Finally, as a result of investigating the level of consensus for each stakeholder, it was confirmed that all stakeholders could agree regardless of the size of the company. The result of this study is expected to as a useful tool among stakeholders in the construction fields that can be able to easily agreed upon.
