국내 발전용댐은 건설 당시 발전목적으로 지어졌으나, 최근 기후 변화로 인해 홍수 및 가뭄의 빈도와 강도가 증가함에 따라 일부분 홍수조절, 환경개선 등의 목적으로 운영되고 있다. 다목적댐과 같이 홍수기에 제한수위를 두어 운영하거나 댐과 보 연계운영 규정에 의해 방류를 수행하기도 한다. 홍수기 제한수위로 인한 수위의 하강은 발전이 목적인 발전량에 손실을 가져오고, 수자원의 이용률 측면에서도 악영향을 끼친다. 현재의 운영 방식이 발전성능 측면에서 재평가 되어야 하며 이를 평가하기 위한 객관적 평가지표나 평가방법이 필요하다. 따라서 본 연구에서는 객관적 평가 지표로 회복탄력성 개념을 도입하여 발전성능에 대한 발전용댐 운영을 평가하고자 한다. 댐의 발전 최적수위를 시스템의 평형상태로 보고 저수위 하강으로 인한 손실, 유입량 및 운영방식에 따른 댐의 수위 회복력을 발전용댐의 회복탄력성으로 정의하였다. 과거 유입량 자료를 활용하여 단일 발전용댐을 모의운영 하였고, 그 결과로 발전수량 시나리오에 따른 회복탄력성을 평가하였다. 회복탄력성과 발전수량, 발전량, 무효방류량, 재난위험일수 등으로 최적 발전방류량을 산정하였다. 향후 발전, 환경개선, 홍수조절에 대한 경제성 평가가 병행된다면 발전수량 운영 기준을 수립하는데 활용이 가능할 것으로 판단된다.

담수 생물종 시식역의 보전을 위해 하천 연결성 유지와 회복이 중요하지만, 하천관리에 있어 이를 고려하기 위한 기초자료나 관련 연구가 부족한 실정이다. 특히 인공장벽(artificial barrier) 영향에 대한 대부분의 연구는 어류이동에 초점을 두고 있거나, 그 공간적 범위를 제한하는 경향이 있다. 본 연구는 강과 하천을 연속체 개념으로 접근하여 생태학적 과정을 방해할 수 있는 모든 인위적 구조물을 인공장벽으로 간주하고, 댐과 저수지, 보와 같이 하천의 종적 연결성을 저해하는 3개 유형의 인공 구조물에 대해 공간자료를 구축하였다. 수치지형도로부터 하천중심선과 수리시설물(보), 호소 및 저수지 경계를 교차(intersection) 분석하여 유형별 구조물의 위치 정보를 추출하고, 기존 자료와의 비교·검증을 통해 자료의 신뢰성을 도모하였다. 인공장벽에 대한 공간자료는 구조물의 유형에 따라 국가하천과 지방하천, 소하천으로 구분하고 낙동강 대권역 내 총 195개 표준유역에 대해 밀도(barrier density)를 계산하였는데, 여기서의 밀도는 하천 연장에 대한 총 인공장벽의 수로 정의(barriers/km)된다. 본 연구의 주요 결과는 낙동강 유역 내 인공 장벽의 밀도와 유형, 하천별 공간분포에 대한 정량적 평가를 포함하고 있으며, 이를 기반으로 수생태계 연결성 회복을 위한 하천관리방안을 모색하고자 하였다. 분석 방법과 결과 등 자세한 내용은 발표를 통해 제시될 예정이다.

This study was carried out in order to study early histologic changes and repair reaction appling to extrusive force for 3rd premolar of adult dogs. After 1 week of extrusive force with elastic chain, one of dogs was sacrified and after 3 weeks retention period, another dog was sacrified. The paraffin sections of samples were stained with Hematoxylin - Eosin and Masson's Trichrome and were examed by light microscopy . The obtained results as follows 1. In Hematoxylin - Eosin and Masson Trichrome stain of control group , the periodontal ligament width was constant from apical third to cervical third of the root and periodontal fiber arrangement was horizontal or oblique in cervical third. oblique in middle third, oblique in apical third of root. in alveolar bone, smooth appearance was shown 2. In Group 1, all periodontal fiber arrangement was oblique toward tooth, and the periodontal ligament width increased Partially PDL was ruptured in apex. In MT stain, immature bone formation was seen at alveolar crest area. Active bone formation was observed along the one side of alveolus, and apical portion of pulp was involved with blood vessel rupture , vacuolization of pulp tissue and hyperemia 3. In Group 2, most periodontal ligament arrangement and PDL width was repaired and fiber density increased. In MT stain, mineralization of immature bone on the alveolar crest was progressed. In pulp, vacuole and hyperemia was diminished and fibrotic change was diminished 4. After 3 week periodontal ligament has more repair ability than pulp tissue. pulp was involved with vacuolization and fibrosis, so it takes more time for repair.

Child abuse and neglect are recently increasing in Korea, and although the government has actively improved the child protection system, the number of abused children and the rate of cases judged as abuse have continuously risen. Given that 75% of child abusers are parents, child abuse and neglect are expected to recur. To prevent such a recurrence, various intervention programs for abused children and their parents are required. The purpose of this study were to design a recovery support service process and investigate the effectiveness of pilot program for families of origin, including neglected(protected) children, to improve the system by which these programs are operated, and formulate policy alternatives that reinforce "family preservation" principles. The pilot program was implemented from June to November 2020 in 4-local healthy family support center. The number of program participants and the frequency of participation in each other differed, because of the difference in number of confirmed coronavirus cases in each region and the requirement for social distancing. Through the program, a community-based service process was developed for neglected(protected) children and their parents, and cooperative networks between related facilities and institutions were established. The study formulated the following recommendations: First, a cooperation system among government departments mandated to provide different services to neglected(protected) children is needed. Second, wider and various channels through which abused children can avail of protective services should be developed within communities. Third, more stable environments for program operation should be cultivated, and cooperative partnerships should be sought for knowledge sharing among relevant government departments. Another necessary measure is for a center to develop its own business model, in which the duplication of services provided by involved organizations is avoided. Finally, clear guidelines, administrative standards, and specific plans for program operation should be arranged. Also regional characteristics are maintained, but services should be standardized.

With the global pandemic in the era of the 4th industrial revolution, the business environment of companies was engulfed by rapid volatility and uncertainty. In particular, in order for an organization to have high competitiveness due to the spread of the flexible work system, relationship management with members of the organization and self-directed job crafting are recognized as important key resources. This study aims to investigate how relational energy and resilience within a corporate organization affect job crafting and to verify the effect of job crafting on individual job performance. For empirical research, 400 valid responses to employees of general companies were analyzed by SPSS 26.0 and Smart PLS 3.0. As a result of the analysis, first, it was confirmed that relational energy did not have a positive (+) effect on task crafting. Second, it was found that relational energy had a positive (+) effect on relational crafting and cognitive crafting, respectively. Third, it was found that resilience had a positive (+) effect on both task crafting, relationship crafting, and cognitive crafting that constitute job crafting. Fourth, it was found that job crafting had a positive (+) effect on individual job performance. Based on these research results, we intend to derive academic and practical implications and provide practical help to follow-up researchers and stakeholders.

분산 객체 시스템을 통합하기 위한 표준인 CORBA(Common Object Request Broker Atchitecture)는 분산 환경에서 더욱 더 자주 발생하는 고장에 대한 회복 수단을 제공하지 않기 때문에, 높은 신뢰성을 요구하는 상업용 어플리케이션에 도입되지 못하고 있다. 이에 따라, CORBA 구조 내에 자체적인 고장 감내 구조를 추가해 신뢰성 높은 서비스를 제공할 수 있는 고장 감내 CORBA에 대한 연구가 진행되고 있다. 그러나, 2000년 4월에 채택된 고장 감내 CORBA에 대한 명세서에서는 객체의 인터페이스를 정의하는 기술 언어인 CORBA IDL(Interface Definition Language)로 객체 단위의 중복과 이를 위한 시스템의 구조 및 각 모듈의 설계를 요약하고 있으나, 그 세부적인 메커니즘이 제시되지 않고 있다. 따라서 본 논문에서는 CORBA에 고장 감내성을 부여하기 위해 세부적인 고장 감내 CORBA를 위한 로깅 및 회복 기법을 제안한다.
