최근 국내 산업구조 및 생활환경의 변화로 도시구조의 고도화, 집중화로 인해 특정관리대상건축물이 다양화됨으로써 안전사고 및 재해양상이 점차 다변화 되어 증가되고 있다. 이에 따라 우리나라 정부에서는 관련 법령에 근거하여 지자체 및 재난관리책임기관 등에서 시설물의 안전관리를 수행하고 있다. 1995년 제정된 "시설물의 안전관리에 관한 특별법"에 근거하여 일정 규모 이상의 1종 및 2종 시설물을 대상으로 정기점검, 정밀점검, 정밀안전진단이 관련전문가에 의하여 주기적으로 수행되고 있으며, "재난 및 안전관리 기본법"에 의하여 특정관리대상시설을 지정하여 주기적인 안전점검이 수행되고 있다. 그러나 수작업에 의한 안전관리 업무 수행과 점검 및 진단 결과에 대한 사후 관리로 관계 업무 주체들에게 과다한 업무가 부과되면서도 안전관리가 효율적 효과적으로 이루어지고 있지 못한 상황이다. 또한 관련 업무가 서로 다른 법령 및 기관에 분산되어 업무의 비효율성을 야기하고 있다. 이에 본 연구는 특정관리대상 건축물의 효율적인 안전관리를 위해 안전관리 업무의 정형화, 안전관리 정보의 통합관리 및 현실적인 업무환경을 고려한 안전관리시스템의 개발을 목적으로 수행되었다.

발 변전설비 중 중요한 설비의 하나로 손꼽히는 변압기는 운전 중 신뢰성 확보가 관건이라 할 수 있다. 최근 안정적 전력공급에 대한 요구가 증대됨에 따라 변압기 이상진단 기술지원 요청이 매년 증가하고 있으며, 특히 절연과 냉각작용이 주기능인 전기절연유의 자체 품질관리는 변압기 예방진단을 위해 시행하고 있는 유중가스분석 못지않게 중요하다. 이에 전력연구원에서는 1999년 전산가 간이측정 기구를 개발하여 별도의 분석의뢰 없이 현장에서 바로 측정하여 절연유의 품질관리에 적용할 수 있도록 한 바 있다. 본 논문은 2008년 1월부터 4개월간 12개 전력관리처에 배분하여 66kV이상 급 모든 변압기의 전산가 현장측정을 완료하고 이에 대한 적용결과와 현장적용성을 검토하였다.

본 논문은 원자력 발전소의 주요 제어계통 중에서 터빈 조속기 제어계통에 관련한 성능평가를 목적으로 한다. 터빈 조속기 계통은 고압의 유압계통으로 구성되어 있어 구동설비가 복잡하다. 복잡한 기계설비는 운전 중 많은 오동작에 의한 고장을 일으키고, 유지보수에 어려움이 있다. 이러한 복잡한 기계설비에 있어 운전원에 의한 기계성능 평가는 불리한 점이 많다. 예를 들어 서로 다른 시간에서 일어나는 같은 상황에 대해 다른 판단을 내릴 수 있다는 점이다. 터빈 조속기 계통의 기계설비에 있어서 터빈 밸브 유압공급 및 구동장치는 각 터빈벨브 자체에 부착되어 있어 터빈벨브를 동작시킨다. 터빈벨브들은 구동기 유압 서보실린더(Actuator Hydraulic Servo Cylinder)에 의해 열리고 압축된 스프링에 의해 닫힌다. 이러한 시스템을 진단하기 위해서 본 논문에서는 밸브의 내부 압력의 특징정보를 입력으로 하는 퍼지이론을 적용하여 터빈 밸브 구동설비의 성능을 판단하고자 한다. 퍼지이론에 적용하기위해 터빈 조속기 제어계통의 고압 터빈 조절 벨브와 고압 터빈 정지 밸브의 압력변화 데이터를 이용한다. 퍼지이론의 적용과정에서 퍼지 Rule은 실제 운전원이 압력변화 데이터에 대한 판단기준을 근거로 하여 정하기로 한다. 그리고 퍼지이론에 적용한 결과를 분석하고 실제 터빈 조속기 계통의 전문가가 판단 결과와 비교하였다.

본 연구는 국내 창업초기투자생태계의 현황을 진단하고 향후 진화의 방향과제를 도출하는 것이 목적이다. 2013년 정부의 투자중심 창업지원 생태계 구축정책에 힘입어 국내 창업초기 투자생태계는 보다 세분화되고 활성화 되고 있다. 종전의 엔젤투자와 VC 투자자로 양분되었던 벤처투자시장에, 특히 창업초기단계 개인엔젤투자조합, 전문엔젤, TIPS, 엑셀러레이터와 창업초기 전용VC 펀드인 인큐베이팅펀드와 청년창업전용투자펀드등에서 최근 마이크로VC펀드에 이르기까지 다양한 창업초기 VC 펀드가 창출되며 다양한 그룹의 투자자들이 생성 진화중이다. 이렇게 창업초기 다양한 투자자그룹이 생성되고 성장하고 있는 이면에는 정부의 매칭투자와 투자연계 R&D 자금이 큰 역할을 하고 있어 투자자들에게는 창업기업에게 Valuation과 투자 위험 관리에 큰 도움을 주고, 창업기업에게는 과도한 지분의 희석 없이 투자자금이 가진 장점의 혜택을 극대화하고 있다. 그러나 본 연구의 국내창업초기 투자생태계 진단결과, 국내 창업투자생태계는 다양한 투자자그룹이 생성되고 성장하고 있지만 서로 다른 투자자 그룹 간 공동투자나 후속투자 연계 등의 협업적 활동 및 회수네트워크 연계 등 활동은 아직 미흡하다. 또한 투자분야 자체가 모바일 및 인터넷서비스 분야에 집중되고 있어, 상대적으로 긴 시간의 보육과 성장검증기간 및 규모 있는 투자를 필요로하는 제조분야는 비중이 약한 편이어서 투자 대상 사업 분야의 다변화 필요하다. 뿐만 아니라 국내 창업초기투자생태계는 창업의 글로벌 사업성과를 내기 위한 글로벌 투자자들과의 연계구조는 미흡한 상황이어 이를 촉진할 방안이 요구된다고 할 수 있다.

Thyroid hemiagenesis is a rare congenital anomaly in which one thyroid lobe fails to develop. Thyroid hemiagenesis usually does not cause clinical symptoms by itself, therefore, this anomaly is detected incidentally during the evaluation of other thyroid disorders. We describe a rare case of thyroid hemiagenesis in a 1-month-old female infant who presented with prolonged jaundice and abnormal laboratory findings of congenital hypothyroidism. The patient showed the characteristic features of thyroid hemiagenesis of the left lobe in Tc-99m pertechnetate scintigraphy and ultrasonography of the thyroid gland. The patient has improved with supportive care, including thyroid hormone replacement. Further long-term follow-up is required for the investigation of recurrence of thyroid abnormalities.

Until recently there were arguments on the existence and the definition of childhood depression. In DSM-III(1980) childhood depression was accepted as the formal psychiatric disorder in childhood. As the diagnostic criteria for childhood depression is less clearly defined than those for other psychiatric disorders as well as prominent age-related variations in depression symptomatology, informations from various sources are very important in accurate diagnosis of childhood depression. Present study reviewed various assessment methods such as self-report questionnaires, interviews, behavior rating scales, structured tests and projective techniques with discussion on the merits and limitations of each method. Also several issues on the reliability and the validity of assessment techniques for childhood depression were discussed.

Purpose : Active perioperative intervention and improvement on surgical technique has decreased the mortality rate of total anomalous pulmonary venous connection (TAPVC); however, when complicated with pulmonary venous obstruction, operative mortality is still high. The purpose of this study was to investigate the clinical course of TAPVC. Methods : Twenty-seven patients who were diagnosed with TAPVC (without other complex heart anomalies) by echocardiogram at Kyungpook National University Hospital from January 1994 to February 2008 were included. Results : Mean age at diagnosis was $28.1{\pm}33.4$ days (1-126 days). Sites of drainage were supracardiac type (15), cardiac (6), infracardiac (5), and mixed (1). Seven patients had pulmonary venous obstruction: 5 with supracardiac type, 1 with cardiac, and 1 with infracardiac. Intraoperative trans-esophageal echocardiograms were performed in 14 patients (58.3%). The operative mortality was 16.7% (4 of 24) and overall hospital mortality (including deaths without operation) was 22.2% (6 of 27). There were 5 postoperative pulmonary venous obstructions. The sites of obstruction were anastomotic in 3 of 5 (60%) patients, and ostial pulmonary vein in the other 2 (40%) patients. Three patients who presented with anastomotic pulmonary venous obstruction underwent reoperation, but all the patients were found to have pulmonary venous anastomotic obstruction. The other 2 patients with ostial pulmonary vein obstruction who had no significant symptoms were diagnosed by routine echocardiographic examination during follow-up. Conclusion : In TAPVC patients, early diagnosis and aggressive surgical management will improve prognosis, and we must pay attention to early and late pulmonary vein restenosis through intraoperative trans-esophageal echocardiogram and peri- and post-operative echocardiographic follow-up examinations.

The records management evaluation system is a system operated by the National Archives of Korea since 2007 based on the 「Public Records Management Act」. As the environment of public records management changes dramatically, there is a growing perception that fundamental improvement is necessary in the operation of this evaluation system. In particular, it is required that the most emphasized area is the customized methods based on the type and characteristics of the institutions. This study focused on the self-evaluation method, which aims to strengthen the autonomous evaluation capability of institutions as a new records management evaluation system in public institutions. In particular, the needs to change toward the self-evaluation method is described in relation to the diversity of the institutions to be evaluated, the specificity of the organizational structure of the archives, and the hierarchy and individuality of the institutions. A self-evaluation system (draft) was designed by which an institution diagnoses the records management work by itself, which aims to improve the level of performance. It also covered the development of evaluation items and indicators, the step-by-step application, and the legal and operational aspects to run the records management evaluation system in phases in public records management practices.

This study aimed at analyzing the current status and further needs of ecological information which is provided with the civil servants in the process of climate change adaptation planning in ecosystem sector and at providing suggestions for future development of ecological knowledge on climate change. Therefore, we conducted a questionary survey titled as "the knowledge-base and information needs for climate change adaptation in ecosystem sector" with the civil servants who are engaged with adaptation practices in the ecology related divisions in 17 regional local governments (RLG) and the affiliated basic local governments (BLG) in Korea. As a result, the characteristics of ecological information which is applied in public practices was analyzed and strategies for improved utilization was suggested. 75% of the respondents (RLG 85% and BLG 72%) were aware of the relativeness between the existence and utilization of ecological information and the execution of climate adaptation practices in ecosystem sector. They were agreed with the necessity of ecological information not only in adaptation practices but also overall affairs in the ecological related division in the local government (RLG 82% and BLG 72%). The current situation of utilizing ecological information which is produced from central orlocal government to civil affairs were only represented as 64 persons (28%) in RLG and 42 persons (18%) in BLG. One of the major obstacles that the respondents confront with when applying ecological information to public practices was deficit of prior knowledge on the ecological information itself, such as awareness of the characteristics of ecological information and the link with public affairs for adaptation plans. Therefore, delivering current knowledge and ecological information on climate change by educational and promotional method is an urgent priority to the civil servant. The future needs on ecological information for local government servants were deduced as basic information on local ecosystem and applied knowledge on local development to meet the biodiversity conservation and ecosystem services at the same time. The respondents expected not only the specific guidelines for using ecological information to apply on the adaptation plans in the relevant divisions of the local governments but also the institution where the usage activation of ecological information would be operated and managed to enhance the information utilizing structure in the local government. In the nation-wide, the capacity of local governments should be enhanced with adaptation knowledge and the application of appropriate information to the public practices by central government's aiding with the better quality of information, its public promotion, and the applicability to civil affairs.
