The smartwork is future-oriented working environment that allows us to engage in work anytime, anywhere conveniently and efficiently by utilizing information and communication technologies in a variety of locations and mobile environments. We proposed a smartwork platform to support the efficient housing management for small housing management companies. Our systems interwork in real time with smart mobile devices and SNS to support high quality housing service for tenants and rental operators. In this paper, we describe real-time complaint handling service using SNS which is a part of smartwork platform for the efficient housing management.

PKI(Public Hey Infrastructure)기반의 공인인증서가 활성화됨에 따라 인터넷뱅킹, 증권거래시스템. 전자입찰, 전자민원 등 신원확인이 요구되는 어플리케이션에 전자서명이 적용되고 있다. 다수의 사용자가 인증서로 로그인과 부인방지를 위한 전자서명을 전송함으로써 서버는 상대적으로 많은 전자서명과 인증서검증을 수행해야 한다. 프로그램 단계에서 검증을 수행하기 위해서는 검증모듈의 API(Application Programming Interface)를 호출해야 하며, 이는 프로그램의 복잡도를 증가시킨다. 이러한 문제는 어플리케이션과 검증이 독립적이지 않기 때문에 검증에 관련된 장애가 발생하면 어플리케이션은 검증모듈에 종속적으로 장애가 발생하게 된다. 본 논문의 검증 에이전트는 서버환경이 서버-클라이언트 또는 웹 어플리케이션에 독립적으로 전자서명 검증을 담당한다. 따라서 어플리케이션은 검증이 필요한 시점에 검증 에이전트를 호출하게 됨으로써 프로그램의 복잡도를 줄이고 서버의 안정성을 향상시킨다.

This case study deals with an excavation blasting carried out at "Sooseo-Pyeongtek ${\bigcirc}$-${\bigcirc}$ section construction site" in the vicinity of residential area. Originally, the sequential blasting (multi-stage blasting) using electric detonators was planed in this area. However, there was a concern that the sequential blasting method could increase the construction cost by delaying the construction period due to possible complaints from local residents. As an alternative, electronic deck blasting technique was taken in order to meet the ground vibration regulation (0.2cm/s, in apartment area) and to keep the construction schedule. The performance of the electronic deck charge blasting was two times better than the sequential blasting with electric detonators and the level of ground vibration was also within the regulatory value (0.2cm/s). In particular, it was shown that the use of electronic detonater eDevII, which was developed for tunnel, could provide more convenient and electrically safer working condition.

PKI(Public Key Infrastructure)기반의 발전으로 인터넷뱅킹, 증권거래시스템, 전자메일, 전자입찰, 전자민원 등 신원확인이 요구되는 어플리케이션에 전자서명과 암호가 적용되고 있다. 각 어플리케이션은 라이브러리를 호출하여 전자서명과 검증, 암호와 복호를 수행한다. PKI기반의 어플리케이션 개발자는 상이한 인증, 암호API(Application Programming Interface)를 호출해야 하며, 이는 프로그램의 복잡도를 증가시킨다. 개발언어와 환경에 따라서 상의한 라이브러리를 사용해야 한다. 제안하는 PKI 에이전트는 개발언어와 어플리케이션에 독립적으로 인증, 암호기능을 수행하고 견과만을 리턴한다. 따라서 어플리케이션은 인증과 암호가 필요한 시점에 검증 에이전트를 호출하게 됨으로써 프로그램의 복잡도를 줄이고 어플리케이션의 안정성을 향상시킨다.

As public services are provided in various forms, including e-government, the level of public demand for public service quality is increasing. Although continuous measurement and improvement of the quality of public services is needed to improve the quality of public services, traditional surveys are costly and time-consuming and have limitations. Therefore, there is a need for an analytical technique that can measure the quality of public services quickly and accurately at any time based on the data generated from public services. In this study, we analyzed the quality of public services based on data using process mining techniques for civil licensing services in N city. It is because the N city's building license complaint service can secure data necessary for analysis and can be spread to other institutions through public service quality management. This study conducted process mining on a total of 3678 building license complaint services in N city for two years from January 2014, and identified process maps and departments with high frequency and long processing time. According to the analysis results, there was a case where a department was crowded or relatively few at a certain point in time. In addition, there was a reasonable doubt that the increase in the number of complaints would increase the time required to complete the complaints. According to the analysis results, the time required to complete the complaint was varied from the same day to a year and 146 days. The cumulative frequency of the top four departments of the Sewage Treatment Division, the Waterworks Division, the Urban Design Division, and the Green Growth Division exceeded 50% and the cumulative frequency of the top nine departments exceeded 70%. Higher departments were limited and there was a great deal of unbalanced load among departments. Most complaint services have a variety of different patterns of processes. Research shows that the number of 'complementary' decisions has the greatest impact on the length of a complaint. This is interpreted as a lengthy period until the completion of the entire complaint is required because the 'complement' decision requires a physical period in which the complainant supplements and submits the documents again. In order to solve these problems, it is possible to drastically reduce the overall processing time of the complaints by preparing thoroughly before the filing of the complaints or in the preparation of the complaints, or the 'complementary' decision of other complaints. By clarifying and disclosing the cause and solution of one of the important data in the system, it helps the complainant to prepare in advance and convinces that the documents prepared by the public information will be passed. The transparency of complaints can be sufficiently predictable. Documents prepared by pre-disclosed information are likely to be processed without problems, which not only shortens the processing period but also improves work efficiency by eliminating the need for renegotiation or multiple tasks from the point of view of the processor. The results of this study can be used to find departments with high burdens of civil complaints at certain points of time and to flexibly manage the workforce allocation between departments. In addition, as a result of analyzing the pattern of the departments participating in the consultation by the characteristics of the complaints, it is possible to use it for automation or recommendation when requesting the consultation department. In addition, by using various data generated during the complaint process and using machine learning techniques, the pattern of the complaint process can be found. It can be used for automation / intelligence of civil complaint processing by making this algorithm and applying it to the system. This study is expected to be used to suggest future public service quality improvement through process mining analysis on civil service.

전력설비에서 발생하는 전자계는 지역 주민들의 가장 큰 민원 제기 대상 중의 하나가 되고 있다. 이로 인해 신설선로의 경우 선로 건설을 반대하거나 선로를 다른 곳으로 이설 요청하는 등 건설 공사가 지연되어 원활한 전력 사업에 많은 지장을 초래하고 있는 실정이다. 이와 같은 현상을 예방하기 위해서는 지역 주민들에게 전자계에 대한 홍보를 통해 이에 대한 정확한 이해를 심어주는 것이 절실하다. 이를 위해서 송전선로에서 발생 가능한 전자계의 크기를 예측할 수 있는 프로그램을 이용하여 정확한 Data를 제시함으로서 주민홍보에 큰 성과를 얻을 수 있을 것으로 믿어진다

The evaluation and analysis method of information system (IS) is studied from the system perspective, the user perspective, and the management viewpoint. The detailed analysis method performs qualitative evaluation by user questionnaire or expert opinion. In this study, Measures the productivity and the effect of building administrative information systems. In the previous study, qualitative productivity and universal effect indicators were used, but in this study, quantitative productivity indicators and indicators specific to administrative complaints were selected. KONEPS, an administrative service system, used electronic contract records and information recorded in the intermediate process. The information was converted into the number of days, and the productivity based on the input manpower was calculated. The effect analysis analyzed the questionnaire related to civil affairs, which is the goal of the administrative work system. Each factor was divided into reflective structural variable and formal structural variable, and internal consistency and multi-collinearity were diagnosed. In order to verify the model, the influence of the work was set as a hypothesis, the reliability was verified according to the descriptive statistics method, the influence was measured through the regression analysis, and the model was analyzed by the multiple regression model path coefficient. Model validation methods are Chi-square (df, p), RMR, GFI, AGFI, NFI, CFI and GFI as indicators according to CFA.
