Construction processes are highly repetitive. A resource entity continuously cycles through work tasks that processes or uses resources. Web-CYCLONE (Halpin 1992) has been accepted as a useful tool for modeling and analyzing a specific operation. However the system has a lack of practicality as follows: (1) it does not efficiently record and keep track of operation models in a database; (2) it does not provide the functions which facilitate to retrieve corresponding model and to update local variables of the model using observed data; (3) it does not automate the complex process that executes simulation experiment, analyzes simulation outputs and generates a report on behalf of the practitioners. Therefore, practitioners have a difficulty in reusing, modifying and analyzing the existing operation models. This study introduces a Client/Server based CYCLONE that improves above-mentioned limitations in the existing Web-CYCLONE. The system was illustrated by revising CSPU in practice.

Jangan-sa is one of the Buddhist temples in the southeastern seaside district, which was restored directly after the termination of Japanese Invasion of Korea in 1592. Recently we could find out 4 records on the constructions of Daeoong - jeon in J angan-sa. These are written in the 12th year of Emperor Soonchi, written in the 8th year of Emperor Geonryung, written in 1947 Buddha Era and written in 1951 Buddha Era. Until the revelation of these records, the present building has been considered to be built in 1657, the 8th year of King Hyojong, based upon Kim Bang - han's "Jangan - sa Daeoong - jeon - gi". Because the gongpo of Daeoong - jeon was finished with the type of the late period of Chosun Dynasty, we doubt of the correction on it's building date, just in the year of 1657. Now we are able to examine the building date and the alteration date, based upon the actual measurement and constructional records of Daeoong - jeon. So to speak, the building destroyed in 1592, had been restored in 1658, the 9th year of King Hyojong and was reconstructed in 1744, the 20th year of King Youngjo. Afterward it was repaired on small scales in 1947 and in 1951. Though this building is considered to be lack of the completeness owing to the later alterations, it is still worthy heritage for the research on the building type at the directly after the termination of Japanese Invasion of Korea in 1592.

The names of Seokgatab and Dabotab are almost generalized among the people along with Bulguksa the most well-known temple in Korea. But, despite this generalized situation, the names of Seokgatab and Dabotab have not secured the clear standpoint till now. It is because the names of Seokgatab and Dabotab can be found only in the 18C documents like and . More complicatedly, in the record of the Goryeo sarira case found during the dismantling of Seokgatab, the name of Seokgatab was 'Mugujeonggwangtab' or 'Seoseoktab'. This paper is to secure the nominal validity of Seokgatab and Dabotab to remove the confusion due to their names and to raise the efficiency of studies related with Bulguksa in the future. First, their names and the problems related with them were summarized in Chapter 2. Based on this critical consciousness, Chapter 3 deals with the tragedy of Asadal related with the creation of the stone pagodas and its symbolic re-interpretation. In this process, we can see that there could be a viewpoint of the great comprehension in them through the completion of 'the Buddhist Nation'. Then, the architectural features of Seokgatab and Dabotab were analyzed in the ritual view point of . Finally, in Chapter 4, on the basis that the viewpoint of one specific sect can not be predominantly applied in the construction of Buddhist land, it is held that Avatamsaka Idea and Saddharma-pundarika Idea can coexist without any conflict. It is shown in the fact that Seokgatab and Dabotab can make harmony together in the Avatamsaka Idea while keeping their names. With these efforts, we can clearly see that the peculiar titles of Seokgatab and Dabotab can be said to secure sufficient validity.

A literature study was conducted on the management of the pavilion of the royal tomb in the late Joseon Dynasty, focusing on "Gakneung Suri Deungnok(Records relating to the repair of royal tombs)". This study analyzed the royal tomb management system, organized the types of damage identified in the building, and examined how the damage status was recorded by type. In the above, the records related to the 1675~1713 repair of three JeongJaGak(Geonwonneung, Sungneung, and Mokneung), which are registered as state-designated cultural properties, are summarized in three aspects: management system, damage status, and expression words. The results of the study are as follows. First, the royal tomb pavilion was regularly inspected by Observator(觀察使) in spring and autumn, and Surunggwan(守陵官) every 5th, and Servant(守僕) regularly inspected every day and night, and also inspected and reported emergency cases of natural disasters or unexpected damage. Second, the damage status of each building was continuously observed and reported for the continuous maintenance of the buildings in the royal tomb. A total of 75 records of damage to the three royal tombs' pavilion were found to have been most frequently inspected, including 19 cases (25.3%), 14 cases (18.7%), 23 cases (30.7%) of the roof, and 19 cases (25.3%) of the roof. Third, the expression of the damage status is confirmed in various ways, such as separation, separation, burst, damage, excitation, moisture, leakage, and exfoliation. Among them, the main damage records were confirmed due to the separation of the base from the peeling, the furniture, cracks, leaks, leaks in the roof, and the collapse of the roof was able to check the damage records.

프로젝트 성공을 위해서는 좋은 역량을 지닌 건설관리자가 필요하다. 특히 건설 프로젝트를 기반으로 이윤창출을 하는 건설사나 CM사 입장에서는 건설관리자인 현장소장이나 CMr를 신중하게 선정해야할 필요성이 있다. 선정하기 위해서는 건설 현장 관리 역력을 진단하는 적절하게 평가하기 위한 기준과 방법이 있어야 한다. 선행 연구에서는 건설관리자의 역량에 관한 많은 연구가 있었으나 두 가지 측면에서 보완해야할 점이 있다. 하나는 측정이 가능하지 않다는 점, 다른 하나는 프로젝트 성과를 직접 개인의 성과를 반영한다는 점이다. 본 연구는 스포츠에서 선수의 역량을 측정하는 지표를 도출 했을 때 사용하는 부호화 분석 기법으로 건설관리자 역량 평가 지표를 도출한다. 부호화 분석 기법은 델파이 방법으로 2차까지 진행하였다. 도출된 '측정 가능한 행동'들로 건설관리자의 역량을 측정할 수 있는 기반을 마련하였다. 이를 통해 각 관리자의 전문성, 리더십, 개인특성 역량을 수치화된 표현으로 나타낼 수 있다. 이는 향후 의사 결정자가 건설관리자를 선정 시 뒷받침 될 수 있는 정보를 제공하고자 한다. 직관에만 의존하였던 기존 방식을 보완하여 기록에 의한 근거로 과학적인 접근방법을 통해 건설관리자를 평가할 수 있으므로 의사결정자들이 필요한 건설관리자를 선정하기 위한 결정을 수월하게 할 수 있도록 도움을 줄 것으로 기대된다.

After the 1884 Home Insurance building in Chicago and 1889 Tower building in New York, 15 Park Row became the tallest building in the USA in 1899 and it held this record for nine years. Completed just before the arrival of the 20^th century, this building deserves to be recognized for the sophistication of its architecture with respect to contextual understanding of the 19^th century historic texture in Lower Manhattan, its uniquely economical floor plans, and its use of natural ventilation and daylight. The compositional techniques using the proportional analysis of its context reflect the highest level of architectural education of its time by its architect Robert H. Robinson. In addition, it also offers a unique glimpse to the state-of-the-art technology of its time regarding its structure, its use of movement systems that was capable of serving 4000 users.

Corrosion of prestressed concrete structures is one of the main challenges that engineers face today. In response to this national need, this paper presents the results of a long-term project that aims at developing a structural health monitoring (SHM) technology for the nondestructive evaluation of prestressed structures. In this paper, the use of permanently installed low profile piezoelectric transducers (PZT) is proposed in order to record the acoustic emissions (AE) along the length of the strand. The results of an accelerated corrosion test are presented and k-means clustering is applied via principal component analysis (PCA) of AE features to provide an accurate diagnosis of the strand health. The proposed approach shows good correlation between acoustic emissions features and strand failure. Moreover, a clustering technique for the identification of false alarms is proposed.

Today, most architectural and engineering historians no longer consider the Home Insurance Building to be the first skyscraper. Despite this, the popular belief remains that William Le Baron Jenny invented the first skyscraper when he designed the Home Insurance Building in 1884. This paper recounts the history of how Jenney won the public debate starting in 1896, despite his building being only a small evolutionary step forward. In that year, a series of letters in The Engineering Record allowed Jenney and his colleagues to engage in a public relations campaign to recast the debate about the first skyscraper to place the Home Insurance Building as the pivotal structure in skyscraper history.

There are stone sculptures diversely shaped in several parts of Gyeongbokgung. Geunjeongjeon is a place where the stone sculptures are intensively placed among the various palace buildings of Gyeongbokgung, and it is more important because it contains the phases of the age of the dynasty and the symbolism of governing philosophy. What can be seen in the structure of auspicious animal sculptures is based on the form of instinctive thought that the heavenly and human order systems are in an organic correspondence with each other, especially with regard to astronomical events such as Samwon Sasin 12jisin 28su. The parts that have been interpreted only in Sasin and 12jisin in the interpretations such as wild dogs, Gyoryong, camels, wolves, and apes were able to clarify the contents by revealing the form of 28su. In particular, as Beopsu Ssangbeopsu at the corner may be related to the guardian deity who governs water, called Yimun, Chimi, and Chimun, it is one of Bibo's ways to protect the palace that was vulnerable to fire. In addition, the shape of the existing 28su placed Dambi, but Ha Woldae at the Geunjeongjeon was assumed to have a camel statue and a planned arrangement of double meaning with the Bibo form of Pungsu Sasinsa, and it is also a feature of the arrangement of Woldae at the Geunjeongjeon. The actual composition of auspicious animals at the Nambogye of Geunjeongjeon was in the order of Haechi, wild dogs, horses and Jujak, and the contents of "Gyeongbokgung Construction Daily Record" were in the order of Haechi, horses, wild dogs, and Jujak. As to different composition layouts, based on the contents of the "Gyeongbok palace Construction Daily Record", the composition of Samjae Cheonjiin (天地人) was interpreted differently from the conventional interpretation of the arrangement of Woldae. All of these forms are associated with defense systems in the four directions and have become animal representations of each direction. The auspicious animal statues placed on the railing of Geunjeongjeon Woldae can be seen as reflected in a single building with the three dimensional personality that includes Pungsu's Bibo personality with the symbolic meaning that reveals the centrality as Jeong Jeon, the nation's best politics let alone the ideological system of the ancient astronomical of the East called Men Heaven Unity.
