This review aims to synthesize social network theories by drawing on the importance of social network perspectives in understanding knowledge management with technology in organizations. I provide an overview of prior social network research with the following core ideas: the primacy of relations between organizational actors, the utility of actors' embeddedness in social fields, the social utility of network connections, and the structural patterning of social life. On top of that, I summarize critical social perspectives (the social capital theory, the structural hole theory, the embeddedness perspective, the social exchange theory, the organizational learning theory, and the innovation diffusion theory) to suggest potential research questions for future studies in social network research in the knowledge management discipline.

This study attempted to estimate the degree of management of oak mushroom farms in Chungcheongnam-do and to provide information to establish oak mushroom cultivation-related policies. The oak mushroom management standard diagnostic table consists of three major categories, growing condition, inoculation management, cultivation management and management administration, along with 20 subcategories. Thus, 209 households of oak mushroom farms were surveyed from 2015 to 2018 in Gongju, Cheongyang, Buyeo and Seochun in Chungcheongnam-do. The average score for the 20 subcategories was 71.5 points (representing a significant level), indicating that these areas have excellent management conditions. The analysis of the management performance indicators revealed a high number of indicators with scores of five or above. The total score was higher, and the amount per bed log and the rate of top-grade products in the total output were also higher, indicating a significant correlation. These findings will provide consulting services to oak mushroom growers as they highlight the correlation between the higher scores of indicators in the oak mushroom management standard diagnostic table and the management performance of farmers. We found that the scores of the indicators for management administration, such as management record and analysis and fund plan were relatively lower than those of other indicators. It is assumed that the owners aging has led to negligence in recording the details on incomes, expenditures, and work and lowered the willingness to make substantial profits. Therefore, it is essential to overcome these problems for profitable oak mushroom farming.

Research activities and discussions on specialized areas reflecting the specificity of landscape construction are necessary. Therefore, this study was conducted with the purpose of presenting basic data for efficient field management by deriving items necessary for safety management in landscape construction fields through experts' opinions. A survey was conducted using Delphi analysis to derive "management items" and "safety management items according to landscape type" for landscape construction field safety for a total of 15 landscape construction specialists. The survey results showed that four top items were derived from the "management items" for the safety of landscape construction fields; they include: "safety and health management organization and education," "industrial safety and health management expenses," "payment of personal protection," and "establishment of safety measures." In addition, two to five items for each higher item appeared and resulted in a total of 13 lower items. Personnel, organization, budget, etc. for safety management are always required in the field, and the monitoring part of whether these elements are working was also taken up as a management item. In the "Management items according to each landscape construction" a total of eight landscape type were distinguished, they include: 'Reinforced concrete work', 'Masonry work', 'Plaster's work', 'Waterproof work', 'Stone masonry work', 'Pavement work', 'Facilities work', and 'Planting work'. Furthermore, two to seven sub-items for each construction type were derived, and a total of 35 management items were presented.

The purpose of this study is to develop the KPIs(Key Performance Indices) needed to improve management and strategy in the dental clinic based on the four perspectives of BSC(Balanced Scorecard). The questionnaire was conducted on 52 dentists approved by Dental Managment Research Committee in Seoul National University as a panel. Using the Delphi technique, the top five KPIs for each point of perspective in BSC were extracted from KPI pools. In the third survey, the top five KPIs of all points were compared with each other through AHP(Analytic Hierarchy Process) method, and priority and overall importance rankings were calculated. The biggest difference in the three level AHP results was the customer perspective took priority to others. In the second survey, the financial perspective, which was number one, was pushed back. The overall significance of KPIs was in the order of customer, internal process, finance, learning and growth perspective, with the exception of medical profits (5th of 20) and new patient growth (10th of 20). We were able to overcome the limitations of the Delphi Technique with the AHP method. In general, the financial perspective in BSC is known to be the most important, but we conclude that the customer perspective is more important through the pairwise comparison survey. In the current dental service market, which is a long-term recession, excessive competition, customer satisfaction and customer relationship management seem to be the first goal to pursue in dental clinic.

2012년 UN이 발표한 전자정부 준비지수(E-Government Readiness Index)에 따르면 우리나라는 지난번에 이어 연속 1위를 차지하였다. 그러나 IMD가 발표한 국가 경쟁력 지수에 의하면 우리나라의 국가경쟁력 지수는 3년 연속 20권에 머물고 있다. 특히, 2012년에는 정부효율성 부분이 2011년 대비 3단계 하락한 25위로 내려앉았고 정보화와 영향이 있는 인프라는 3년간 20위인 상황이다. 이는 정보화의 발전이 정부업무 효율에 영향을 주지 못하고 있다는 반증일 수 있다. 본 연구에서는 이러한 현상을 정보화 라이프 싸이클 관점에서(기획-예산-구축 운영-평가) 분석하였다. 그 결과 각 단계별 정보의 연계 및 합리적인 추적관리 부재와 체계적인 계획에 따른 정보화관리가 미흡한 것으로 나타났다. 이를 해결하기 위해 아키텍처적인 방법을 활용해 개선방안을 제시하였다.

An amphibious inspection robot system (hereafter AIROS) is being developed to visually inspect the in-containment refueling storage water tank (hereafter IRWST) strainer in APR1400 instead of a human diver. Four IRWST strainers are located in the IRWST, which is filled with boric acid water. Each strainer has 108 sub-assembly strainer fin modules that should be inspected with the VT-3 method according to Reg. guide 1.82 and the operation manual. AIROS has 6 thrusters for submarine voyage and 4 legs for walking on the top of the strainer. An inverse kinematic algorithm was implemented in the robot controller for exact walking on the top of the IRWST strainer. The IRWST strainer has several top cross braces that are extruded on the top of the strainer, which can be obstacles of walking on the strainer, to maintain the frame of the strainer. Therefore, a robot leg should arrive at the position beside the top cross brace. For this reason, we used an image processing technique to find the top cross brace in the sole camera image. The sole camera image is processed to find the existence of the top cross brace using the cross edge detection algorithm in real time. A 5-DOF robot arm that has multiple camera modules for simultaneous inspection of both sides can penetrate narrow gaps. For intuitive presentation of inspection results and for management of inspection data, inspection images are stored in the control PC with camera angles and positions to synthesize and merge the images. The synthesized images are then mapped in a 3D CAD model of the IRWST strainer with the location information. An IRWST strainer mock-up was fabricated to teach the robot arm scanning and gaiting. It is important to arrive at the designated position for inserting the robot arm into all of the gaps. Exact position control without anchor under the water is not easy. Therefore, we designed the multi leg robot for the role of anchoring and positioning. Quadruped robot design of installing sole cameras was a new approach for the exact and stable position control on the IRWST strainer, unlike a traditional robot for underwater facility inspection. The developed robot will be practically used to enhance the efficiency and reliability of the inspection of nuclear power plant components.
