In order to enhance their own customer satisfaction index that is one of the top level managerial performance indices, Internet communication service providers endeavor onto establishing a total quality management system. Specifically, it is under discussion that some critical Internet communication network quality characteristics closely related to customer satisfaction index should be controlled aiming to this managerial goal. This paper presents an application scheme of I-MR control charts for monitoring Internet communication network quality characteristics. This statistical quality control scheme generates a signal to practitioners when it detects the network quality characteristics out-of control. It is designed based on; 1) individual measurements; and 2) moving ranges between two consecutive individual measurements collected with a constant time interval. Empirical analyses are illustrated to estimate the expected quality improvement ratios that can be realized with the application scheme proposed in this paper. Assuming that the assignable causes can be revealed and eradicated, regarding two Internet communication services A, B, seven network quality characteristics for each service, eleven distinct measuring spots for each network quality characteristic, the expected quality improvement ratios are calculated with which the effect of the application scheme is evaluated. Results show the ranges of the expected quality improvement ratios; 1) Service A, (1) mean (0.31%-11.44%), (2) standard deviation (9.82%-71.10%): 2) Service B, (1) mean (0.29%-17.64%), (2) standard deviation (8.05%-60.59%). Hence, It is anticipated that the I-MR control charts based application scheme can be effective not only to improving the mean and dispersion of the network quality characteristics concerned but also to maintaining the network quality characteristics in-control consequently.

The purpose of this research is to propose a practical guideline for activating EA which has been operated in the public institutions. For this purpose, how EA is being operated in the public sector, was analyzed from the viewpoint of IT Governance and on the basis of the result, key activities for EA managers could be developed. The key activities were also compared between the two different groups in terms of EA Maturity Level and the difference in the key activities between the two were examined. As a result, it was found that the use of EA has effect on building and improving IT management systems. It is suggested that the Relational Mechanism should be better understood and recognized as necessary activities for activating EA. In addition, the higher the level of EA maturity is, the more likely such various effects as the enhancement of IT management system, user satisfaction, IT utilization, and the improvement of business can be produced. This result could be interpreted that such desired outcomes of EA could be realized only when EA is actively utilized.

Unlike building construction projects, where the activity is repeatedly carried out in a limited area, civil engineering projects such as roads and railroads are carried out in a linear type in a horizontal working space over several tens of kilometers. Each activity is managed with a station number that has a unit of distance from the starting point to the end point. For this reason, since the work location information of the activity is a major management factor, the Gantt chart system that expresses only schedule information may have limitations. In this study, authors propose a method for constructing a linear schedule chart that can simultaneously express schedule information indicating the start and finish dates and location information indicating the start and end positions of each activity, and develop a system for generating a linear schedule chart. In the study, the coordinate axes of the linear schedule chart consisted of distance and date values on the X and Y axes, respectively, and each activity was expressed as a symbol that can infer the type of work to increase the visibility of the linear schedule chart compared to the simple bar chart method. The linear schedule chart generation system was reviewed for practical applicability by utilizing the actual schedule data of bridge structures in a railroad project.

Recently, the construction industry has been pursuing the rationalization of its various systems through informatization. Procurement is a highly important element of the construction process, as it is directly related to the cost and quality of a construction project. In addition, procurement management of resources is in an indivisible relation, so that it is significant to link each other effectively. This study proposed construction activity and basic data connected to cost summary work for the categorization and utilization of resources. This study connected that activity to detailed items of material and labor cost, and proposed a procurement planning model of resources by activity that can utilize all resources and information. In addition, this model can classify resources and information by various forms. We found that the utilization of this procurement planning model will be higher because it can grasp various problems that occur in the passive procurement and provide additional functions that can be modified.

Sinkholes have occurred in various places around the world and concerns about public safety have been raised in recent years. Particularly, a ground subsidence may occur due to a variety of conditions when developing underground spaces. Ground subsidence refers to the sinking of the Earth's surface caused by the loss of the soil constituting ground due to a certain artificial cause in the ground. Ground subsidence is induced by artificial causes such as the leakage of water supply/sewage pipes and groundwater disturbance, and it is different from a sinkhole, where the sinking of the Earth's surface is induced by the cavity formed due to the melting of limestone in the ground with limestone bedrock. In recent underground development in the urban areas of Korea, damages to surrounding buildings have frequently led to many difficulties with civil complaints and compensation issues, and the collapse of some buildings has resulted in the loss of lives and property. Accordingly, the central government has legislated the Special Act on Underground Safety Management, which will take effect from January 1, 2018. This law specifies an underground safety management system for securing underground safety, under which underground safety impact assessment is performed for projects involving underground excavation work that exceeds a certain size, and safety inspection is regularly performed for underground facilities and the surrounding ground. In this study, the contents of the special act on underground safety management are reviewed, and the direction of development of underground safety policy for preparing preemptive underground safety management preparation and response system is suggested.

The purpose of this study was to understand the effectiveness of oral health education (OHE) or oral hygiene instruction (OHI) involving professional plaque control/removal, as compared to conventional plaque control/removal. By means of a systematic review of the literature, in the review of literature by using systematic method, Korean articles of plaque control including OHE or OHI, were studied in order to analyze and conclude the literature to enhance oral health. We found that self and professional plaque control/removal, in addition to tooth brushing instructions, decreased incidence and prevalence of loss of teeth. Taken together, professional mechanical plaque removals were most effective 4~5 visits every 1~2 weeks. Use of disclosing agent was more effective than oral education or model education. In line with oral hygiene education, professional brushing, oral prophylaxis, scaling and root planing, it was advisable to repeat the training according to the characteristics of the patient. Routine OHE or OHI would be help to increase to oral health. For a quality of life related oral health, reliability and validity of data are needed to develop and its data should be applied to dental health insurance policy.
