"공공기록물관리에 관한 법률"에 따르면 모든 공공기관은 최소 1명 이상의 기록물관리 전문요원을 배치하여야 하지만 현재 교육지원청 및 군 관련 기관들은 다른 기관에 비해 배치 실적이 저조한 실정이다. 그 중 일부 교육지원청에서는 그러한 문제점을 타계하기 위해 '기록관리 학습동아리(CoP)'를 운영하고 있었다. 이에 대한 운영 실태를 파악하기 위해 정보공개를 통한 전국 교육지원청을 전수 조사, 동아리의 현황을 분석하였으며 동아리의 존재/부존재 기관을 나누어 설문조사를 진행하였다. 분석 결과, 기록관리 학습동아리가 실질적인 기록관리업무 수행과 개인의 능력 향상에 도움이 되고 있음을 확인할 수 있었다. 반면 기록물관리 전문요원이 배치될 때까지 동아리가 한시적으로 기록관리업무를 일부 수행한다 할지라도 근본적으로는 기록물관리 전문요원을 충원하여 체계적인 기록관리가 이루어질 수 있도록 조치해야 한다는 의견이 수렴되었다. 또한 기록관리 학습동아리 운영상의 장애요인을 도출하고 이를 해결하기 위한 활성화방안을 제안하였다.

Koreatech has adopted a long-term co-op program called IPP (Industry Professional Practice) to address problems in higher education of Korea since 2012, but it was anticipated to face many difficulties in implementing the program due to lack of relevant experiences in Korea. In this regard, a performance evaluation scheme was urgently required to judge the effectiveness of the Co-op program and improve the operational efficiency at the same time. This study aimed to develop comprehensive performance evaluation criteria for the co-op programs on the basis of Kirkpatrick's four-level performance evaluation model for training programs, and apply it to a real Co-op operation to test its feasibility. For this purpose, thorough review on the training program evaluation literature and in-depth analyses of overseas cases of co-op performance evaluation were conducted. Then, a set of Co-op performance evaluation criteria was developed and applied to the Koreatech's Co-op operation in 2013. Two Co-op student questionnaire surveys were administered before and after Co-op terms to measure students' reactions to the Co-op program (Level 1) and changes in participating students' attitudes and competencies (Level 2). In addition, employment rates of Co-op participating and non-participating students were compared (Level 4). The analysis findings showed that participating students were quite satisfied with their jobs and companies, and the Co-op program was effective to a certain degree at enhancing non-major competencies and attitudes to occupation of students. Together, the employment rate of Co-op participants, particularly in small- and medium-sized companies, grew significantly in comparison with that of non-participants. In the last part, several directions for improving the effectiveness of the Co-op programs were discussed.

This study was performed to test the feasibility of thermophilic ($55^{\circ}$) co-digestion of municipal sewage sludge and food wastes. The management variables of co-digestion were the mixed ratios of municipal sewage sludge and food waste hydraulic retention times (HRTs). During the operation of thermophilic co-digestion, the reactor pH ranged from 7.0 to 7.5 and the reactor alkalinity remained above 3,200 to 4,000 mg/L as $CaCO_3$. The volatile fatty acids concentration increased as the HRT shortened from 20 days to 10 days and the mixture ratio increased to 1:4, but did not reach toxic levels for co-digestion of sewage sludge and food wastes. Methane productivity increased gradually as the organic loading rate increased. Maximum methane productivity reached 1.03v/v-d at an HRT of 10 days and at the mixture ratio of 1:4. The TVS removal efficiency decreased from 70.6% to 58.3% as the HRT shortened from 20 days to 10 days. TVS removal efficiency ranged from 57.0% to 77% during the entire operation. It is likely that thermophilic co-digestion of sewage sludge and food wastes is a very effective method both to environmentally treat food waste and to economically produce gas for energy.

There is no doubt Six Sigma is an excellent concept to improve quality of product or service. However, limitations to Six Sigma's implementation process have been discovered that are related to Six Sigma's foundation in statistical methods. The limitations of Six Sigma are overcome by the advantages of a strategic CoP (Community of Practice). Therefore, this research tries to build a strategic CoP for implementing Six Sigma. The method for building a strategic CoP is suggested, and then a case study of a real company is presented.

The IAQ management in subway cabin is very important for the enhancement of the amenity and health of passengers because the subway carries many passengers in a relatively short time mostly in urban area. However, since the ventilation of most subway cabins are performed by simple opening of doors at each stations, the IAQ management is not easy. In this study, we measured some IAQ factors (temperature, relative humidity, particulate matters, CO, and $CO_2$ concentration) of subway cabin in Seoul area. The results showed that the IAQ of the cabin was relatively acceptable. However, $CO_2$ concentrations were higher than 1,000 ppm in most cases. $CO_2$ concentration was mostly proportional to the number of passengers in cabin. Therefore, new method to relieve the $CO_2$ concentration is urgently required.

Utilizing outside knowledge for innovation is an important task for companies in the competitive economy. Due to the rapid advance in the internet communication technology, the number and quality of innovation sourcing methods are increasing. We select co-creation, personalization and in-house R&D as the representative forms of innovation sourcing and suggest a game theory model that enables the comparative analysis between them. The decision and surplus outcome of the innovation mechanisms are compared under various settings of the input parameters of the model. The stakeholders voluntarily participate into all mechanisms when the product price is moderately high and the participation cost is low, while co-creation is the only feasible one when the product quality is niche. When the participation cost is relatively high, personalization outperforms co-creation.

The co-precipitation process plays a key role in the decontamination of radionuclides from low and intermediate levels of liquid waste. For that reason, the removal of Cs ions from waste solution by the co-precipitation method was carried out. A simulated liquid waste (¹³³Cs) was prepared from a 0.1 M CsCl solution, while wastewater generated by washing steel ash served as a representative of radioactive cesium solution (¹³⁷Cs). By co-precipitation, potassium ferrocyanide was applied for the adsorption of Cs ions, while nickel nitrate and iron sulfate were selected for supporting the precipitation. The amount of residual Cs ions in the CsCl solution after precipitation and filtration was determined by ICP-OES, while the radioactivity of ¹³⁷Cs was measured using a gamma-ray spectrometer. After cesium removal, the amount of cesium appearing in both XRD and SEM-EDS was analyzed. The removal efficiency of ¹³³Cs was 60.21% and 51.86% for nickel nitrate and iron sulfate, respectively. For the ash-washing solution, the removal efficiency of ¹³⁷Cs was revealed to be more than 99.91% by both chemical agents. This implied that the co-precipitation process is an excellent strategy for the effective removal of radioactive cesium in waste solution treatment.

The Wolsong Nuclear Power Plant (NPP) operates an on-site spent fuel dry storage facility using concrete silo and vertical module systems. This facility must be safely maintained until the spent nuclear fuel (SNF) is transferred to an external interim or final disposal facility, aligning with national policies on spent nuclear fuel management. The concrete silo system, operational since 1992, requires an aging management review for its long-term operation and potential license renewal. This involves comparing aging management programs of different dry storage systems against the U.S. NRC's guidelines for license renewal of spent nuclear fuel dry storage facilities and the U.S. DOE's program for long-term storage. Based on this comparison, a specific aging management program for the silo system was developed. Furthermore, the facility's current practices-periodic checks of surface dose rate, contamination, weld integrity, leakage, surface and groundwater, cumulative dose, and concrete structure-were evaluated for their suitability in managing the silo system's aging. Based on this review, several improvements were proposed.
