IoT(Internet of Things) 기술이 급속도로 발전함에 따라 다양한 분야에 적용되고 있으며, 새로운 부가가치를 창출하고 있다. 최근에는 IoT 기술을 접목하여 도시 내부에 자동화된 농작물 재배시설을 설비하여 재배된 농작물을 직접 현지에 바로 공급할 수 있는 운영시스템을 구축하고 있다. 본 연구는 도심지 내부의 건물 옥상이나 농작물을 재배할 수 있는 임의의 공간에 온실을 설치하여 작물을 재배할 수 있는 환경을 원격으로 관리하는데 있다. 온실 내부의 환경 데이터를 계측하기 위한 온도, 습도, 조도, 토양상태, CO2 센스를 설치하여 온실 내부의 환경을 라즈베리파이2(raspberry Pi2)를 활용하여 계측하였다. 원격으로의 데이터 전송은 Wi-Fi를 이용하여 데이터를 전송하였으며, 중앙에서 관리된 관리정보를 통하여 온실 하우스의 내부 환경을 제어할 수 도록 모터(motor), 환풍기 팬, 조명용 Led, 워터 펌프 등을 제어하도록 하였다. 본 논문의 연구결과를 통하여 비닐하우스의 내부 상태를 계측하고, 다양한 구동장치를 제어할 수 있도록 IoT 기술을 편리하게 적용할 수 있는 라즈베리파이와 원격관리용 스마트 앱(app.)을 이용하여 비닐하우스 내부 관경을 편리하게 관리할 수 있음을 확인하였다.

In this study, a field model experiment was performed to analyze the bahavior of slope during failure. It was analyzed through x-MR control chart method with inverse displacement and K-value. As a result, the portent was confirmed at 4 minutes before slope failure in Case 1. The change of the control limit line according to moving range was analyzed and it was effective to apply K = 3. Use of the inverse displacement and x-MR control chart method will be useful for the prediction of abnormal behavior through quick and objective judgment. Prediction of slope failure using control chart method can be used as basic data of slope measurement management standard, and it can contribute in reduction of life and property damage caused by slope disaster.

사용자들은 분산 P2P 환경을 통해 대량의 멀티미디어 콘텐츠를 쉽게 제공 밭을 수 있는 환경이 되었다. 또한 고용량 모바일 기기의 발전과 보급이 확산됨에 따라 사용자들은 사진, 음악, 동영상과 같은 멀티미디어 콘텐츠를 대량으로 휴대하며 이용할 수 있게 되었다. 그러나, 이러한 대량의 멀티미디어 콘텐츠 관리는 사용자 각자에게 맡겨져 있어 콘텐츠 관리를 어렵게 하고 있는 현실이다. 본 논문에서는 분산 P2P 환경에서 멀티미디어 콘텐츠의 공유와 추천을 통해 사용자에게 적합한 콘텐츠를 제공하고, 제공된 콘텐츠는 모바일 동기화 서비스를 통해 모바일 기기로 저장하고 관리되는 #분산 P2P 환경에서 모바일 동기화 서비스를 통한 멀티미디어 콘텐츠 추천 시스템#을 설계하고 실험하였다. 제안된 시스템은 사용자 선호 프로파일 정보로 협업 필터링을 통해 분산 P2P 환경에서 공유된 멀티미디어 콘텐츠 중에서 적합한 콘텐츠를 추천해 주고, 추천된 콘텐츠는 푸쉬 서비스를 통해 모바일 기기로 저장되며. 모바일 기기 사용자의 행동에 따라 모바일 동기화 서비스를 통해 사용자 모바일 기기의 콘텐츠를 관리한다. 이처럼 제안된 시스템은 콘텐츠 추천과 모바일 동기화 서비스로 능동적인 콘텐츠 관리를 제공하여 사용자에게 효율적인 콘텐츠 관리 기법과 활용 방법을 제공 할 수 있다.

There is a lot of recent research to provide services of dynamic distributed contents in P2P-based distributed environment. Distributed services of contents objects, however, have problems in QoS and dynamic management of segments. This paper proposed a new segment management method for the service of P2P-based distributed contents. The proposed method manages groups by the SGM(Segment Group Manager). The SGM manages streaming efficiently by the grouping of segments to be served in P2P environment. The segments in the same group cooperate for improved QoS using the management structure based on the distance and relationship. The distance-based management structure is for the improvement of retrieval efficiency while the relationship-based management structure is for the improvement of service ratio. The simulation results of the proposed method showed improvements in average transmission efficiency and average service rate. The improvement is 8% - 30% in average transmission efficiency and 10% - 30% in average service rate.

The whole objective of two papers in series was to develop the framework of an information management system (IMS) for soil-contaminated sites. In the previous first paper (Hwang et al., 2006), current status of information management in our country and the developed countries was investigated and four suggestions were made. In this work (the second paper), the future-oriented framework for information system of soil contamination sites and several suggestions were made.

This study was a descriptive research study performed to identify the degree and correlation of variables and also explain the factors that influence self-efficacy of diabetes management. The participants were 150 diabetes patients who visited a primary medical institution in K city in Korea from September 17, 2015, to October 15, 2015. The data were analyzed using descriptive statistics, t-tests, ANOVA, Pearson correlation coefficients, and multiple regression with SPSS 18.0. Significant differences in age and education were detected in self-efficacy of diabetes management according to general characteristics. The levels of self-management knowledge and diabetes management self-efficacy were shown to be positively correlated. The levels of diabetes management self-efficacy and distress as well as levels of self-management knowledge and distress were shown to be negatively correlated. The significant factors influencing diabetes management self-efficacy were distress and self-management knowledge. The results suggest that appropriate diabetes management self-efficacy programs should be provided in order to improve self-management knowledge and decrease distress in type 2 diabetes patients. This study provides basic data to promote the effective education and development of arbitration in order to enhance self-efficacy of diabetes management.

This study analyzed the effect of human resource management on the performance of franchise restaurant workers. First, employment management of franchisees did not have statistically significant effect on business performance. Second, evaluation management (p<.05, ${\beta}=1.887$) showed a significant effect on job improvement, but did not affect financial performance significantly. Third, career management (p<.05, ${\beta}=1.715$) was found to have an impact on financial performance, but it did not significantly affect job performance. Fourth, there was a somewhat higher correlation between job improvement and job management (.441), job improvement and evaluation management (.476), p<.01, and financial performance and employment management (.375) (.356), and financial performance and career management (.371) were found to be correlated with p<.05 significance level. This study analyzes the effect of human resources management on the performance of franchise restaurant workers, and finds out the importance of characteristics of factors such as recruitment management, career management, and evaluation management. Research has significance.

The purpose of this study was to identify the sanitation management items of school foodservice suppliers that require improvement, by assessing their sanitation practices with food commodities. Our field assessment was performed using a total of 20 vendors supplying agricultural products, meat products, seafoods and processed products; all were located in the Seoul and Gyeonggi areas. The assessment tool for sanitation management was composed of 93 checklist items and was used to evaluate seven different categories; the facility and environment, management of the facility and equipment, food materials management, process control, water management, personal hygiene management, and laboratory instrument management. A score of two was given for "satisfactory", one for "fair", and zero for "unsatisfactory". The overall average supplier score was 1.7/2.0 (85.8%). The score of the seafood vendors was highest at 1.9 (95.4%), while the lowest score of 1.3 (65.7%) occurred with the processed product suppliers. Among the sanitation management categories, water management was scored at 2.0, while inspection management was lowest at 1.4. The subcategories indicating needed improvements for the processed product suppliers were raw materials, storage, transport and recall. For the agricultural product suppliers it was preparation management. furthermore, one item within the laboratory instrument management category was unsatisfactory for both the agricultural and processed product suppliers. In conclusion, these results can be used to develop sanitation management procedures for suppliers, as well as by administration agencies to evaluate and guide those suppliers.
