현장이 개설되어 공사가 진행되어지는 중에 발생하는 예상할 수 있는 악재들, 즉 주변민원, 기능인력부족, 자재나 장비 파동, 급격한 기후의 변화(폭설, 폭우 등), 예상보다 긴 장마, 가설물의 붕괴 및 전도 등의 요인들은 그 원인이 현장내부가 아닌 외적인 환경에 의한 것이었고 따라서 단위현장 1개소가 아닌 일정지역에 있는 현장들이 공통으로 겪게되는 일종의 난관이었다. 그러나 현장 내에서 작업 중에 발생하는 사망사고는 일단 현장내 원인으로 발생되고, 타 현장과는 공유할 수 없는 사안이라는 점에서 앞서 밝힌 외적요인들과는 근본적으로 다르다 하겠다.(중략)

The purpose of this study is to suggest a model analysing spatio-temporal characteristics of the civil complaints for the officially assessed land price based on big data mining. Specifically, in this study, the underlying reasons for the civil complaints were found from the spatio-temporal perspectives, rather than the institutional factors, and a model was suggested monitoring a trend of the occurrence of such complaints. The official documents of 6,481 civil complaints for the officially assessed land price in the district of Jung-gu of Incheon Metropolitan City over the period from 2006 to 2015 along with their temporal and spatial poperties were collected and used for the analysis. Frequencies of major key words were examined by using a text mining method. Correlations among mafor key words were studied through the social network analysis. By calculating term frequency(TF) and term frequency-inverse document frequency(TF-IDF), which correspond to the weighted value of key words, I identified the major key words for the occurrence of the civil complaint for the officially assessed land price. Then the spatio-temporal characteristics of the civil complaints were examined by analysing hot spot based on the statistics of Getis-Ord $Gi^*$. It was found that the characteristic of civil complaints for the officially assessed land price were changing, forming a cluster that is linked spatio-temporally. Using text mining and social network analysis method, we could find out that the occurrence reason of civil complaints for the officially assessed land price could be identified quantitatively based on natural language. TF and TF-IDF, the weighted averages of key words, can be used as main explanatory variables to analyze spatio-temporal characteristics of civil complaints for the officially assessed land price since these statistics are different over time across different regions.

도시를 중심으로 지속적으로 발생하고 있는 초고속 네트워크서비스의 안정성을 확보하기 위해 KT는 경제적이고 안정된 구조의 직경 1,000mm 이하의 무인통신구를 건설하고 있다. 도심지에서 무인통신구 공사 허가 및 민원을 유발하는 요인으로 공사시 발생하는 이수 처리장치인 디샌더(Desander)의 소음과 진동이 있다. 소음과 진동은 불쾌감을 유발하고 인근 건물에 영향을 줄 수 있기 때문에 지속적인 관리가 필요하다. 본 연구는 소음과 진동의 주 원인인 디샌더가 발생하는 진동 특성을 모델링하고 설계인자를 이용한 최적화를 통해 진동전달 량의 최소화에 관한 것으로 이를 통해 디샌더의 설계단계에서부터 민원 유발원인인 진동과 소음을 최소화 하고자 한다.

The conflict is gradually increasing and becoming more serious in Korea. Especially, there are many conflict among stakeholders in public construction projects and its economic, social effects are enormous. This negatively affects the performance of construction projects, such as schedule delay and increasing construction costs. Complaints are often extended to public conflicts so that complaints have to be considered for conflict management. However, complaints and conflicts were distinguished and have been studied differently in previous studies. In this research, the literature that analyzed complaints and conflict factors was reviewed, and the complaint that included the conflict factors were categorized and derived.

Companion animals are increasingly being recognized as members of society in outdoor public spaces. However, the presence of dogs in cities has become a subject of conflict between pet owners and non-pet owners, causing problems in terms of hygiene and noise. This study was conducted to analyze public complaint data using the keywords 'dog,' 'pet,' and 'puppy' through text mining techniques to identify the causes of conflicts in outdoor public spaces related to dogs and to identify key issues. The main findings of the study are as follows. First, the majority of dog-related complaints were related to the use of outdoor public spaces. Second, different types of outdoor public spaces have different spatial issues. Third, there were a total of four topics of dog-related complaints: 'Requesting a dog playground', 'Raising safety issues related to animals', 'Using facilities other than dog-only areas', and 'Requesting increased park management and enforcement related to pet tickets'. This study analyzed the perceptions of citizens surrounding pets at a time when the creation and use of public spaces related to pets are expanding. In particular, it is significant in that it applied a new method of collecting public opinions by adopting complaint data that clearly presents problems and requests.

오늘날과 잘은 정보통신 기술의 급속한 발전은 기업의 경쟁우위와 비영리조직의 서비스 증대에 많은 변화를 가져왔다. 이러한 변화에 대응하여 기업은 정보기술을 활용하여 비용절감은 물론, 생산성 향상, 경쟁력 강화, 조직 혁신을 도모하였으며, 정부기관이 주도하는 비영리조직은 일반 행정 분야를 비롯한 민원인을 위한 공공서비스의 분야에 이르기까지 공정하고 투명한 서비스 혁신을 추진하고 있다. 현재까지 기업의 정보시스템 아웃소싱 위험요인에 대한 많은 연구가 있었지만 비영리조직의 정보시스템 아웃소싱 도입단계별 위험요인에 연구는 미미한 실정이다. 이에 본 연구에서는 비영리조직의 정보시스템 아웃소싱에 대한 이론적 토대를 제공하기 위하여 비영리조직의 특수성을 고려한 아웃소싱 도입단계별 위험요인의 프로토타입을 개발하고자 한다.

As recent construction projects have gradually become larger in size and complex, construction documents such as drawings and specifications revealed the limitations that can not express all the necessary information. Due to the lack of stipulations on the contract, disputes arise among contracting parties. Traditionally, many construction companies in Korea make an unfair agreement with the clients so that the irrational items are included in their contract documents. Potential dispute factors are triggered as a result of misleading or omitted items on the written documents. This paper analyzed the civic counseling cases obtained from the public procurement service in Korea, and identified the potential dispute factors that can occur during pre-dispute stage alone with their influence analysis. The results found from this study can be used for the development of checklists that prevent the dispute in the process of construction projects.

This practical study investigates the effects of job satisfaction as a result of the stresses felt by many dispatchers who work in the subway industry in the Seoul metropolitan area. Factors that cause stress are assessed. The organization system, inappropriate compensation, workplace culture, and job requirements, among several types of organizational stresses are significantly related to job satisfaction. The results of the analysis indicate that there is a close link between job satisfaction and dispatcher communication factors. This paper suggests stress-relief measures for dispatchers who must handle a variety of civil complaints and improper communications with field departments based on the analysis of the answers to descriptive questionnaire items.

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.

각종 공장에서 발생되는 오염물질 중 악취물질은 작업환경을 나쁘게 하고 작업자의 건강을 해치고 있으며, 외부로 방출될 경우 공장 혹은 주택지까지 이동하여 지역주민의 민원의 요인이 되고 있다. 악취는 사람의 관능에 따라 즉시 폐해를 주며, 특히 황화수소와 메틸메르캅탑은 아주 적은 농도에서도 악취를 발생시키고, 그 자극이 메스꺼움, 두통, 식욕감퇴, 호흡곤란 및 알레르기 현상 등의 인체의 자각반응을 나타내므로 이들 악취물질들의 제거는 필수적이라 하겠다.(중략)
