Methods for measuring the physical workload of construction workers are classified into posture assessment techniques (i.e., OWAS, RULA, etc.) and physiological measurement techniques (i.e., EMG, heart rate, etc.). The one does not quantify the workload on a specific body part of a worker by considering the weight of the hand tools or materials on hand and time for holding a particular posture. This paper presents a procedure for evaluating a physical demand using the electromyography (EMG) sensor. This study compares the EMG measurement and the posture assessment. The case study is carried out on a masonry operation.

As the use of advanced quality materials in constructions has been increasing since 1980 with the improvements in the quality of life and economic scale, there has been drastic increase in constructions using stones for the internal and external construction materials. However, the reality is where many problems rise due to improper construction and management of uncertified stones which shorten the expiry date of the stones and act as the factor causing defects in buildings. Such defects not only bring economic losses but also influence consumer choice and act as risk factors to demand expansion of stone market. Therefore, the object of this study lies on proposing plans to prevent personal and economical losses due to repetitive defects by deriving the types of defects generated by process in stone constructions and identify the causes. Also, proposing construction process management plans as the measure for defect prevention, analyzing problems of stone constructions followed by the whole proves of design, construction and maintenance of stones, and solving such problems through appropriate participation of professional consultants depending on situations.

This study intends to suggest the effective methods for water leakage prevention around the windows in stone works to up-grade the outdoor public space that has been taken much portion of apartment housing trends. The subjects of the study was selected among the domestic subcontractors of stone works. There are four methods for water leakage prevention around the windows; Firstly, the painting water-proof method after the masonry. Secondly, the urethane water-proof method after galvanizing panels on the gap. Thirdly, the separation method between stone and substructure and the last one is water-proof method that they put some water-proof screen between stone and substructure with the EPDM sheets. According to the analysis of the water-proof effects, constructability and planning, we could approach to conclusion that the most influent items to the water-leakage are the filling material's deformation, the state of oxygenation and deterioration of work skill. Among the water-proof methods in construction the EPDM sheet is most excellent water-proof method to meet the technical conditions. However, we have to apply it to stone works as a water-proof method for the decrease of the leakage defects after standardizing the materials, test and construction skill because there are many work skills according the subcontractors.

The purpose of this study is to analyze the problem of confusing the names of Chinese granite used in Korean construction work and suggest the improvement plans for them. Interviews of the experts from the stone company, studies on the existing research literature, and analyses of construction work documents of the 23 construction works which used Chinese granite were carried out to analyze the real condition of name confusion of granite stone. In the analytical result of the real condition, name confusion was classified into 4 types and problems derived from it were done into 4 ones. An additional survey was carried out targeting 34 masonry experts to draw the improvement plans based on the analytical results of the real condition of name confusion. The results show that the most fundamental solution is to continue to make efforts to use exact names when main agents related to construction works communicate with each other regarding Chinese granite stone and the process to make out construction contract documents.

A number of construction companies in Korea invest considerable human and financial resources to construct a system for managing apartment defect data and for categorizing repair tasks. Thus, this study proposes machine learning models to automatically classify defect complaint text-data into one of the sub categories of 'finishing work' (i.e., one of the defect repair tasks). In the proposed models, we employed two word representation methods (Bag-of-words, Term Frequency-Inverse Document Frequency (TF-IDF)) and two machine learning classifiers (Support Vector Machine, Random Forest). In particular, we conducted both binary- and multi- classification tasks to classify 9 sub categories of finishing work: home appliance installation work, paperwork, painting work, plastering work, interior masonry work, plaster finishing work, indoor furniture installation work, kitchen facility installation work, and tiling work. The machine learning classifiers using the TF-IDF representation method and Random Forest classification achieved more than 90% accuracy, precision, recall, and F1 score. We shed light on the possibility of constructing automated defect classification systems based on the proposed machine learning models.

In 1972, the mural painting of Kuknakjon, which is National Treasure No. 15, at Pongjongsa was taken to pieces. From 1999. 9. 8 to 1999. 9. 15,we were precisely investigated with infrared vidicon television, video camera and so forth. The result of investigation shows that contents of the mural painting consisted of paintings of flowers and birds, paintings of Taoist hermits with supernatural powers and old historic figure paintings (In the investigated mural paintings, there were paintings about pheasant or magpie on splendid peony, figures such as Lee tae baek(이태백) and Baek lakchon(백악천) known as old chinese poets, Chang yang(장량) and Hwangsok kong(황석공) known as old historic figures and Paebok(백복), and Choksongja(적송자) known as Taoist hermits.)It is noted that the mural painting was under the influence of the later Choson culture included Taoistic and folk artistic than buddhistic contents such as painting of Bodhisattva, Arhat and apsara. Later, each mural painting will be more investigated in respect of Buddhism art historic value, and we'll make conservative treatment plan based on its result.

This study is to carry out literary study about the subject of Martial Study in Song Dynasty which was in charge of military strategy education. Martial Examination and Martial Study were related to military officials in China, and also have important value of historical materials in physical education dealing with martial arts as traditional physical activity. To be a military official would be possible to correspond with such requirements as knowledge that sports experts should have, leadership as a leader, and ability reinforcement through physical training, and the effort to pass Martial examination as the chance of status rise contributed to developing sports and culture because the necessity of training military arts was emphasized in social situations. Martial Study establishment became a clue of creating and spreading the notion that General should have virtue and justice as an ideological style of new-Confucianism (neo-Confucianism and Sung Confucianism) in Song Dynasty. After founded in 1043 and equipped with a formal aspect in 1072, Martial Study got the political effect and improved national competitiveness while its function of cultivating and selecting excellent capable persons was going on smoothly. Educational contents in Martial Study were understanding and flexibly applying the skills of infantrymen, cavalrymen, and bowmen and the meanings and theories of confucian classics, testing problem solutions of reality, and teaching the measures of the problem. Martial Study included three aspects of military capable persons, war, and weapons and took charge of the function of education, selection, and promotion, steadily supporting development and continuance of Martial examination institution.
