The Construction industry has been dealing with much trouble due to global economic recession and domestic political trends emphasizing on welfare than development. Consequently, domestic construction market has been dramatically shrunk during the last a few years, and international market has become the only potential solution for the industry. However, there has been lack of efforts in developing a quantified measure of global competencies for Korean engineering and construction organizations. This study attempted to develop quantified indices for Korean engineering and construction contractors with which the level of global construction competencies can be objectively monitored. In doing so, a survey questionnaire was developed to identify relative importances of core competency elements which were derived from extensive literature reviews and experts interviews. AHP (Analytic Hierarchy Process) was employed as a main analysis method in developing quantification measures. The analysis results reveal little differences in competency requirements between engineering and construction firms and it implies that the global market becomes more integrated and requires a total solution for a construction project. The developed core competency measures can be used to quantify the level of preparedness of Korean engineering and construction firms at the time of evaluation and also be used as a basis for performance benchmarking indicators if they are compared with business showings.

Purpose: To report the results of arthroscope assisted posterior cruciate ligament reconstruction without tourniquet, which has not yet been reported in documents within the country. Materials and Methods: Out of the 75 cases of arthroscope assisted posterior cruciate ligament reconstruction on patients with posterior cruciate ligament damage from January, 1998 to May,2003 in this hospital, study was done on 49 cases of patients with isolated posterior cruciate ligament damage, excluding 16 cases of patients who were applied tourniquet in extraarticular operation due to combined damage such as in lateral collateral ligament and posterolateral collateral ligament, and 10 cases where the postoperative observation period was less than 12 months. There were 13 cases where reconstruction was done using autogenous bone-patella tendon-bone, 19 cases using allogenous bone-patella tendon-bone, and 17 cases using allogenous achilles tendon. For assessment, the 49 cases were compared using Lysholm knee scoring scale. Results: The average duration of operation was 105 minutes. There were no severe complications such as swelling, bleeding, infection etc . Assessment results attained by Lysholm knee scoring scale was 74(fair) for cases where autogenous bone-patella ten-don-bone was used,75(fair) for cases where allogenous achilles tendon was used, and 76(fair) for cases where allogenous bone-patella tendon-bone was used. Conclusion: There are no difficulties to perform the arthroscopic assisted posterior cruciate ligament reconstruction. Reconstruction without tourniquet can be thought to prevent complications that could follow when using it.

Domestric Construction & Engineering market has been long in recession due to the global economic crisis. Domestic construction industries consequently looks at overseas construction markets where relatively more construction projects are constantly required. In order to provide meaningful information for Korean engineering companies to keep the pace with the changes in the construction industry, various construction related date and statistics are analyzed. In addition, previous research from the related organizations and construction engineering companies are closely reviewed. Investigation of preliminary data and research have been conducted to draw remedies for their overseas expansion. Moreover, it is attempted to classify foreign markets as the Asia, Africa and etc. (Europe, North America/the Pacific and Latin America) to provide the list of first target countries and its regional market information focusing on their bidding system. This study had tried to show comparative analysis of different bidding procedures between Korea and the selected countries to suggest measures of improvements for the domestic bidding system. Finally, this study suggested policy recommendations to meet the requirement of bid qualification to advance the global market that was suggested with validated clustering bidding data. 장기화되어가는 세계 경제위기와 더불어 내수시장은 침체의 덫을 벗어나지 못하고 있고 따라서 필연적으로 국내 건설업계는 대규모 사업이 지속적으로 발주되고 있는 해외 건설시장에 눈을 돌리고 있다. 시공을 중심으로 한 대규모의 기업들은 그나마 해외시장의 개척에 성과를 얻어가고 있으나, 중소 규모의 업체 특히 규모가 영세하고 해외 실적이 부족한 엔지니어링 업계는 해외시장 진출에 큰 어려움을 겪고 있다. 이에 본 연구에서는 해외 시장에 기진출한 경험이 매우 적거나 앞으로의 진출을 희망하고 있는 업체들을 위하여 해외시장 진출의 기초 정보 분석을 수행하였다. 해외 건설시장 진출을 위해 관련기관 및 유관단체의 선행연구와 건설 엔지니어링 업체들의 건설통계자료를 수집하고, 그 진출 개선방안 도출을 위한 기초자료로써 분석을 수행했다. 해외시장을 중동, 아시아, 아프리카, 기타(유럽, 북미 태평양, 중남미)지역 등으로 구분하고 각 권역별로 진출 유망국가를 선정하여 최종 선정된 국가의 입낙찰 관련 제도 정보를 중심으로 개괄적인 조사와 분석을 수행하였다. 또한, 국내외 해당국가들의 사업 입찰시 자격요건 충족 및 입 낙찰절차의 차이점을 비교 분석하여 국내 입 낙찰제도의 개선방안을 제시하였다. 본 연구를 통하여 제시된 분석은 해외 진출을 원하는 기업들의 기초정보 확보에 합리적인 기여를 할 것으로 기대된다.

건설산업 제도개선을 위한 분할·분리 발주 제도의 선진화 방안 연구

김상범,조지훈,Kim, Sang-Bum,Cho, Ji-Hoon 한국건설관리학회 2013 한국건설관리학회 논문집 Vol.14 No.2

국내 건설산업은 경직된 산업 구조와 건설 생산 활동에 대한 비효율적인 제도적 규제 등으로 인해 성장세가 저하되고 경쟁력이 뒤떨어지는 등의 문제점이 지적되고 있다. 현행 분할 분리발주 제도의 경우 국가 계약법에서는 분할발주는 원칙적으로 금지하고 있으나, 그 예외 조항으로 두고 있어 전기, 정보통신, 기계설비, 건축폐기물 공종의 경우 분할발주가 의무화 가능하고, 소방시설공사의 경우 의무화 추진을 위한 노력으로 소방시설공사업법 일부개정법률안을 발의하는 등 지속적으로 의무화 추진중이다. 기계설비공사업은 분할발주 관련 법률은 없으나 국가계약법 제68조 제3호를 근거하여 일부 시 도 교육청에서는 기계설비공사의 분리발주 확대 추진하고 있는 실정이며, 공종별 별도 법안을 추진하고 있는 공종도 있는 것으로 파악되고 있다. 이에 본 연구에서는 분리분할 발주에 대한 제도 분석 및 분리발주에 대한 전문가의견 청취 및 유관기관별 의견을 정리하여 건설산업 제도 선진화 방안을 제시하고자 한다. 이에 본 연구에서는 발주자의 효율적인 발주방식의 선택권 확보차원에서 발주자의 역량 및 프로젝트의 특성 등에 따라 분할 발주 여부를 유연하게 결정할 수 있도록 분리분할발주 제도의 개선안을 제시하여 건설사업차원에서의 효율적이고 생산적인 건설생산이 가능한 유연한 건설사업 수행 체계를 형성할 수 있는 기반을, 그리고 건설 산업차원에서는 국내 건설산업의 균형 발전과 함께 국제 경쟁력 향상을 고려한 구조를 제공할 수 있는 방안을 제시하고자 한다. Procurement System for Korean construction industry has mainly been controlled by the complicated regulatory system which has been recognized as unflexible and remotely separated from the global standard. This has been identified by many Korean construction experts as one of the main reasons that hamper the Korean construction industry becoming the global leader. One commonly discussed regulatory system is the compulsory multiple contracting system that has been enforced for a long time. According to the Korean governmental contracting law 68-3, all construction projects cannot be divided into separate contracting packages with a few exceptions. Exceptions stated in the law include construction activities related electrical, Information communication, fire-fighting, and cultural assets which all are governed by the separate laws/acts controlled by the different governmental bodies. This research is to closely investigate multiple prime contracting system that has been compulsory in Korean construction industry and to provide policy recommendations to these restrictions. Although, there has been a long history of this compulsory contracting system, this study attempted to provide objective analysis on current status of the system as well as global standard on the issue. This study suggests main considerations when considering different contracting system such as rights of owners, flexibilities of regulatory systems, and efficiencies of conducting a construction project. It is envisioned that recommendations from this study, if accepted by the regulatory bodies, would improve the Korean construction contraction system by making it more compatible with global standard. Moreover, these would help making the Korean industry more effective in terms of regulatory restrictions.

This study set out to shed more specific light onto sales managers' coaching and salespersons'organizational commitment and role perceptions, which have been proven to work as important variables in salespersons' performance. It thus conducted an in-depth investigation into the overall sale management activities of sales managers from five high-sales organizations and five low-sales organizations and analyzed differences between them. The interviews of the ten sales managers were combined and analyzed. As a result, the ones from the high-sales organizations demonstrated the following characteristics: first, the salespersons of the high-sales organizations were strongly committed to the goals and values of their organizations. Second, the salespersons of the high-sales organizations had clear perceptions of their roles and showed relatively fewer role conflicts than those of the low-sales organizations. Third, the sales managers of the high-sales organizations demonstrated coaching behavior strongly. They provided positive feedback and role models for the salespersons to follow, thus earning great respect from them and maintaining trust-based relationships with them. And finally, the sales managers' organizational commitment and role perceptions had positive impacts on the salespersons' organizational commitment and role perceptions. Those research findings indicate that sales managers' organizational commitment and role perceptions can be a positive role model to salespersons and that such a role model can have influences on salespersons' performances as part of the characteristics of coaching behavior.

본 연구에서는 음절 단위의 HMM을 이용하여 발성한 문장에 대해 화자 적응화 할 수 있는 방법을 제안하였다. 문장에 대한 음절 단위의 추출은 음절HMM의 연결과 viterbi세그멘테이션으로 자동화하였고, 화자 적응화는 소량의 문장과 문장의 추가에서도 시켄셜적으로 적응화할 수 있는 MAPE(최대 사후 확률 추정)를 이용한 학습으로 수행하였다. 신문 사설에서 취한 문장에 대하여 화자 적응화한 경우의 인식을 71.8%로 적응화 전의 결과보다 37% 향상되었다. In this study, the method of speaker adaptation for uttered sentence using syllable unit hmm is proposed. Segmentation of syllable unit for sentence is performed automatically by concatenation of syllable unit hmm and viterbi segmentation. Speaker adaptation is performed using MAPE(Maximum A Posteriori Probabillity Estimation) which can adapt any small amount of adaptation speech data and add one sequentially. For newspaper editorial continuous speech, the recognition rates of adaptation of HMM was 71.8% which is approximately 37% improvement over that of unadapted HMM

The construction industry has been leading the growth of the nation's economy not only by providing with various infrastructure projects but also by positively impaction related industries such as crating numerous job opportunities. Relevant statistics show the production amount of construction taking about 17.5% of the GDP (Gross Domestic Product). In spite of its positive impacts on the economy, image of Korea construction industry is generally reflected as negative mainly because of its environmental disruption, low payment, bribe, fraudulent work and inefficiency. It brings students to be reluctant choosing the construction industry as their carrier path and governmental and principal research status. Therefore it has been difficult to recruit highly qualitied human resources to the industry while the morale of the whole industry has gradually become demoralized. To improve this stand, many domestic researchers carried out research projects for improving the image of Korea Construction Industry. This study also sympathizes with necessity of improving the negative image of construction industry to remain as one of the leading industry in the 21st century. Especially, this study focused on finding important factors which have significant influences on the image of the industry. Through out the research, image influence factors was identified by rigorous literature review and interviews as industrial and academic experts. Factors, then, categorized and used as the main framework for the survey which designed to fine the degree of impacts on the image of the construction industry. In analyzing the survey results, various statistical techniques was employed including factor analysis, Chi-Square-Test, Correlation Analysis and Multiple Linear Regression. Identified as the most influent factors to the image of the construction industry include morale of construction employee, and prospects the industry which of the judgement by payment, impacts on nation's economy, future of the industry, etc.

This research focuses on development of the conceptual cost estimation models for I.L.M box girder bridge. The current conceptual cost estimation for public construction projects is dependent on governmental average unit price references which has been regarded as inaccurate and unreliable by many experts. Therefore, there have been strong demands for developing a better way of conceptual cost estimating methods. This research has proposed three different conceptual cost estimating method for a P.S.C. girder bridge built with the I.L.M method. Model (I) attempts to seek the proper breakdown of standard works that are accountable for more than 95 percentage in total cost and calculates the amount of standard work's materials from the standard section and volume of I.L.M box girder bridge. Model (II) utilizes a correlation analysis (coefficient over 0.6 or more) between breakdown of standard works and input data that would be considered available information in preliminary design phase. Model(III) obtains conceptual estimating through multiple-regression analysis between the breakdown of standard works and all of input data related to them. In order to validate the clustering of coverage in the preliminary design phase, the variation of I.L.M cost coverage from multiple-regression analysis[model(III)] has been investigated which result in between -3.76% and 11.79%, comparing with AACE(Association for the Advancement of Cost Engineering) which informs its variation between -5% and +15% in the design phase. The model proposed from this research are envisioned to be improved to a great distinct if reliable cost date for P.S.C. girder bridges can be continually collected with reasonable accuracies.
