The purpose of this study is to forecasts monthly dam inflow and to examine the practical use of weather forecasting information using Neuro-Fuzzy system. The Neuro-Fuzzy algorithm adopted in this study is the ANFIS(Adaptive Neuro-Fuzzy Inference System) in which neural network theory is combined with fuzzy theory. The ANFIS model can experience difficulties in selection of control rule by a space partition because the number of control value increases rapidly as the number of fuzzy variable increases. In an effort to overcome this drawback, this study uses the subtractive clustering, which is one of fuzzy clustering methods. Also, this study proposed a method to convert weather forecasting information that is qualitative as quantitative. When monthly dam inflow forecasts are performed by using ANFIS, which is compared forecasting result of model that is consisted of observed data to observed data and weather forecasting data. As a forecasting result, it can be found that using the weather forecasting information is helpful to increase the forecastibility of the models and the neuro-fuzzy system gives us relatively more accurate forecasts. In conclusion, ANFIS which is better monthly dam inflow forecast when it uses weather forecasting information than it does not use one.

Through the above studies, labor service staffing alternative was derived. The alternatives presented is based on a general discussion about direct construction of an interior architecture constructors labor staffing system from construction industry’s overall view. The resources such as the leading domestic, and international studies, government reports and statistics are carefully used. This paper summarizes the contents of through the following theorems: Chapter One presents background and objectives of the study. Chapter also specifies the study perspective and the methods and describes the process of this study. The careful consideration of previous studies have revealed the necessity and significance of the study. Chapter Two presents: focuses on identifying the problems in the industry, the analysis on the reality of construction and the role of construction industry. The discussion on the whole construction industry, and previous studies on overall structure in construction industry and production, and statistical analysis from country's leading research institutions and related organizations, support's the chapter's subject matter. Chapter Three verifies the production efficiency of interior architecture constructors' new production measures on theoretical basis, through legal analysis of the loading contractor status issues which is a primary production in the form of professional construction contractors, and analysis on the institutional issues through service report. Chapter Four presents alternatives: (1) As a plan on a direct construction of an interior architecture constructors, establishment of co-produced DB (database) of construction labor workforce and management plan proposed from the analytical point of the producer. (2) As a plan on activation of direct construction of an interior architecture constructors and the realistic application of labor workforce DB (database), application of integrated operating system is the alternative possibility that is within in the scope of institutional limitations. Chapter Five conclusions are presented. To conduct a detailed study on construction labor management plan in direct interior architecture construction, analysis is divided into five main selections with following purposes. First, find a stable supply of workers seeking labor. Second, look for a way to place labor force with a temporary team that works around the president to the institution. Third, look at how to build, utilize, and examine the expected effects of human resources and labor needs DB(database). Fourth, review the effectiveness of building co-DB among personnels in same labor. Fifth, find labor market driven integrated management plan. By integrating above process of above, the conclusion on the operating plan for the activation of the direct construction of an interior architecture constructors is summarized into five objectives. First, the examined conclusion on stable supply of labor follows: 1.The same industry sharing labor DB is a viable alternative. The method is proposed. 2.After careful analysis on domestic and international cases, systematically established ranking system and wage standards targeting labor workers needs to be established. The method is proposed. Second, the examined conclusion on placing labor force with a temporary team that works around the president to the institution follows: 1.Proposed to expand and reorganize the Korean Construction Engineer's Association traditional system that is centered towards people with education and credentials 2.Proposed to expand the Korean Construction Specialty Technician Association's certification system for people entering the construction industry without credentials. Third, the examined conclusion on how to build, utilize, and examine the expected effects of human resources and labor needs DB (database) follows: 1.Proposed to build personal, user, and government DB's three-party system and the need to rebuild user-friendly labor DB on government-led construction workforce management system. 2.Proposed in details that the core in the need and expected effects to build human resources labor DB is to reorganize the labor management structure from the team that is centered around the captain to producer-centered structure. 3.Proposed how to ensure the consistency in the labor wages and diversity in employment through the establishment of labor force DB. Fourth, the examined conclusion on the review of the effectiveness of building co-DB among personnels in same labor follows: 1.Users can benefit under the direct labor for the consistency possession of labor and minimizing the imbalance while providing stable supply and reducing the general administrative expenses. 2.Labor can be assured of stable employment, and wages. The technology that is depended on the team and the captain can transition into the diverse, more individualized technology 3.There are two forms of co-DB building which is a compromise between companies in the same industry. One is a naturally occurring structure and the other is involves contractors or ordering body's intervention. This study focused on the latter. Fifth, the examined conclusion on finding labor market driven, integrated management plan follows: 1.Integrated operational configuration requires differ according to the company's sales volume, project's characteristics, and organizational forms. There are direct operations, combined operations, bulk outsourced operating methods. This paper proposes a outsourced operating system. 2.The largest expected effect from integrated operation is to reduce the cost,and to disperse the business risk. 3.It is clear that the integrated operation of interior architecture constructors can overcome the limitations of small businesses while pushing directly construction. 4.The owner's separate payment in operations cost and of construction cost is preferable and the method is proposed. For a interior architecture constructors to serve fully as a professional construction, establishing the collaboration in same industry and co-production in the form of copurchase is a necessary. Of course they can cause a variety of issues, but to build the autogenous conditions that can make each interior architecture construction business to lead its own way is the significance of this paper is to present. 우리나라의 건설시장은 일반건설업과 전문건설업으로 업역이 구분되어 있으나 규모의 불균형과 원도급과 하도급의 종속적 관계로 인하여 원래의 업역 구분의 취지인 건설업의 기술적 발전과 생산성 향상 등의 목적을 달성하는데 어려움이 있다. 이러한 현상은 하도급의 구조적 문제를 제도적으로 해결하지 못한 것이 가장 큰 원인이며, 그 동안 정부에서 추진해온 정책들이 근본적 치유 보다는 형식의 틀에 건설업의 생산 행위를 강제함으로서 건설업의 국가 경쟁력과 효율성을 저하시킨 주요한 이유였다. 연구는 다음의 4가지로 나누어 논의를 진행하도록 한다. 첫째, 건설산업의 업역구조와 생산구조를 고찰하여 정확한 현황을 파악한 후 전문건설업 특히 실내건축공사업에 유효한 적용 방법이 있는지 파악한다. 둘째, 전문건설업의 현황 고찰을 통하여 실내건축공사업의 제도적 문제를 선행연구와 통계자료등을 통하여 분석하고 생산자 입장에서 개선방법을 연구 한다. 셋째, 전문건설업의 하도급, 재하도급 현황을 선행연구와 정부용역보고서를 중심으로 분석하여 제도적 개선과 자구노력의 방안을 알아보도록 한다. 넷째, 선행연구자료와 연구자의 생산자 입장에서의 분석방법으로 실내건축공사업의 직접시공을 위한 방안을 찾아보고 대안을 제시한다. 본 연구의 구성과 각 장의 전개방법은 다음과 같다. 제1장에서는 연구의 배경 및 목적을 중심으로 연구관점과 방법을 명시하면서 본 연구가 진행되는 과정을 설명한다. 또한 선행연구고찰을 통한 연구의 필요성과 의의를 밝히고 있다. 제2장에서는 건설산업 전반에 관한 고찰을 통하여 건설업 업역구조와 생산구조의 선행연구자료와 국가기관 및 관련 단체의 통계자료등을 통하여 건설업의 실태를 분석하고 전문건설업의 역할을 알아봄으로서 문제점을 파악하는데 주력한다. 제3장에서는 전문건설업의 주요 생산형태인 하도급과 재하도급의 법률적 해석과 현황 문제점을 관계법령을 통하여 알아보고 용역보고서를 통한 제도적 문제점을 분석함으로서 실내건축공사업의 생산방식의 효율화 방안을 검증하기 위한 이론적 바탕을 알아보았다. 제4장에서는 실내건축공사업의 직접시공을 위한 방안으로 건설노무인력 공동DB구축 및 운영방안을 생산자 입장에서 분석하여 제안한다. 실내건축공사업의 직접시공 활성화 방안으로 건설노무인력DB의 현실적 활용방법과 통합운영시스템의 적용이 현재의 직접시공을 위한 제도적 범위내에서 선택할 수 있는 대안임을 제시한다. 제5장에서는 연구의 결론으로 논문의 의의와 시사점을 정리한다. 실내건축공사업의 직접시공을 위한 건설노무인력 운영방안을 구체적으로 연구하기 위하여 다음의 5가지 목적으로 나누어 분석을 진행하였다. 첫째, 노무인력의 안정적 수급방안을 모색하고 둘째, 비정규직 형태의 팀, 반장을 중심으로한 고용특성을 가진 노무인력을 제도권에 진입시키기 위한 방법을 찾아보고 셋째, 노무인력의 DB구축방법과 필요성 그리고 활용방안과 기대효과를 구체적으로 살펴본 후 넷째, 동일 업종간 노무인력 공동DB 구축의 효율성을 검토하고 다섯째, 시장주도형 노무인력 통합운영방안을 찾아본다. 이러한 연구과정을 통하여 도출된 결론은 실내건축공사업이 전문건설업역의 범위에서 생산 활동을 통한 기업 가치를 높을 수 있는 방법은 현실적 제도의 범위 내에서 최종생산단계 역할을 하고 있는 건설노무제공자들의 안정적 수급구조 확보가 절대적인 조건이라는 분석결과에 의거하여 동일 업종간 건설노무인력의 공동DB구축과 활용이 가장 효과적인 방안으로 분석되었다. 또한 이를 시행하기 위한 구체적 방법으로 통합운영시스템을 제안하여, 직접시공을 위한 기반여건의 조성과 건설노무인력의 운영체계의 현실화로 건설산업 전반에 인력수급에 관한 불합리한 요소들을 개선함으로서 기존 노무인력의 체계화와 신규 건설인력의 유인 여건을 확보하여 기술 및 산업경쟁력을 향상시킬 수 있기를 기대해 본다.

Hypoxemia is not rare during one-lung ventilation (OLV) for thoracic surgery. If hypoxemia occurs, surgery is interrupted for rescue ventilation such as continuous positive airway pressure (CPAP) and two lung ventilation (TLV). Apneic oxygen insufflation (AOI) may prevent hypoxemia during OLV but rarely been studied. Therefore, we designed this randomized controlled trial to verify the effectiveness of the AOI technique on hypoxemia prevention during OLV. Patients undergoing open or thoracoscopic pulmonary lobectomy in a tertiary care academic hospital from September 2015 to December 2015 were included in this study. Patients were randomly assigned to one of two arms: non-AOI group or AOI group (n=45, each). In the AOI group, 3 L/min of oxygen was insufflated for 30 minutes (OLV45) from 15 minutes after initiation of the OLV (OLV15) through the operated side of the double lumen tube. The primary endpoint of this study was the occurrence of hypoxemia (SpO2 < 90%) and subsequent resort to CPAP or TLV. The secondary endpoints were ΔPaO2 (PaO2 at OLV45 – PaO2 at OLV15), duration of operation and postoperative complications. The incidence of SpO2 < 90% and subsequent rescue measures was higher in the non-AOI group than the AOI group (18% vs. 0%; P = 0006). ΔPaO2 was smaller in the AOI group than the non-AOI group (-29 mmHg vs. -69 mmHg; P = 0.005). Duration of surgery and the incidence of complications were not different between the groups. Our study proved that AOI decreases the incidence of hypoxemia during OLV for thoracic surgery.
