The purpose of this study is to analyze the effects of smart construction equipment applied at the construction site of the first smart city in the Korea and derive an application strategy for the utilization of smart construction equipment. To achieve this, aythors examined the practical effects and issues of safety systems and construction systems utilizing machine guidance (MG) technology, which is a representative smart construction equipment used in civil engineering construction sites. Both the MG safety system and MG construction system were found to be sufficiently effective in improving construction productivity. However, there are challenges that need to be addressed, such as the approval process for work results using MG systems, system changes due to frequent replacement of on-site equipment, and usability improvements for elderly on-site workers. The study presented some solutions that have been implemented on-site to address these issues. The utilization effects and issues presented in the study were analyzed through direct feedback from workers and managers who have utilized the MG technology on-site for a considerable period of time. These results can be used as preliminary data for the similar construction projects, considering the limited availability of empirical analysis data for equipment automation.

Physical properties and impedance-humidity characteristics of carbon nitride films were investigated for micro-humidity-sensors. Carbon nitride films were deposited in low temperature and low power for application of semiconductor fabrication process, and empirical equation was proposed for thickness evaluation. Deposited films had an uniform and compact surface comparing with previously reported results, which was expected a good candidate for humidity sensing materials. Carbon nitride humidity sensors based on Si substrate revealed good humidity-impedance characteristics with a wide range of relative humidity and showed low hysteresis.

Problems related to chronic alcohol use common in neuropsychiatric fields, but the concerns about alcoholic neuropathy is much lower to clinicians than other alcohol related problems. We experienced a 54 year-old male alcohol dependent patient who complained of the weakness in both lower legs. He suddenly could not stand or walk showing the flaccid tetraparesis and areflexia on hospital day 7. We should differentiate alcoholic neuropathy from Guillain-Barre syndrome clinically. He showed abnormal electromyographic finding with predominantly no sensory potential and no sensory nerve conduction velocity in lower legs. We successfully treated alcoholic neuropathic pain with amitryptiline without any side effect. According to this case, Psychiatrists should pay more attention to alcoholic neuropathy in alcohol related patients via detailed physical examination, and treat them more aggressively without any fear.

본 연구는 폐경기 여성에서의 에스트로젠 치료에 따른 우울정도와 주의집중력의 차이를 평가하기 위해 폐경이 된 지 1년이 지난 폐경기 여성을 대상으로 사용군과 비 사용군으로 나누어 각각 30명을 대상으로 했다. 검사 도구는 한흥무 등(1986)이 표준화 한 Beck의 Beck depression inventory(BDI)를 사용하여 사용군과 비사용군으로 나누어 평가하였다. 그리고 주의 집중력의 평가는 K-WAIS(염태호 등 1992)의 소검사 항목인 숫자외우기와 바꿔쓰기을 사용하였다. 에스트로젠 사용군과 비사용군에서 각각의 검사 항목에 대해 t-test로서 유의한 차이가 있는지 비교하였다. 더불어 사용군과 비사용군에서 혈중 에스트라디올 농도를 측정하여 각 검사항목과 상관관계가 있는지 Pearson's correlation(r)를 통해 확인하였다. 결과는 BDI와 숫자외우기 중 바로 따라 외우기에서만 유의한 차이가 있었으며 다른 항목에서는 차이가 없었다. 그리고 혈중 에스트라디올 농도와 검사 항목간의 유의한 상관관계는 없었다. 본 실험을 통해 에스트로젠이 폐경기 여성에서 우울증상의 경감에 효과적이나 기억력 및 주의집중력에는 효과가 없음을 확인할 수 있었다. Objectives : The purpose of this study was to evaluate the difference of depressive symptoms and attention between estrogen user and non-user in postmenopausal women. Methods : 30 Estrogen users and 30 non-users were participated in this study. They were all menopausal for at least 1 year and have 12 or more education years. We used BDI(Beck depression inventory), digit span and digit symbol to evaluate depressive symptoms and attention in both groups. We also measured the plasma estradiol level and identified the correlation between estradiol level and BDI, digit span and digit symbol. Results : The demographic data was not different between both groups. Estrogen users scored higher than non-users in digit span(forward) and lower than non-users in BDI. The correlation between estradiol level and BDI, digit span and digit symbol was not significant. Conclusion : Estrogen replacement therapy was effective in alleviating depressive symptoms but ineffective in improving attention in postmenopausal women.

본 연구는 최근 COVID-19와 같이 국가적으로 정부 및 공무원의 역할이 절실히 요구되는 현실에서 공무원의 적극행정 강화를 위해 공직 내 변혁적리더십과 공무원의 적극행정과의 관계성에 대해 연구하고자 하였다. 구체적으로는 공직사회 상사의 변혁적리더십이 공무원의 행태(학습지향성, 자기효능감, 공공봉사동기)를 매개로 공무원의 적극행정에 미치는 영향을 연구하고자 하였다. 또한 변혁적리더십, 학습지향성, 자기효능감과 공공봉사동기와의 관계에서, 그리고 공공봉사동기와 적극행정과의 관계에서 채용제도와 직급의 영향 여부를 검증하여 정부 인사전략에 실무적 시사점을 제시하고자 하였다. 연구결과, 변혁적리더십은 학습지향성, 자기효능감과 공공봉사동기에 각각 정(+)의 영향, 학습지향성과 자기효능감은 공공봉사동기에 각각 정(+)의 영향을 미치고, 공공봉사동기는 적극행정에 정(+)의 영향을 미치는 것으로 나타났다. 또한 변혁적리더십은 학습지향성과 자기효능감 각각을 매개로 공공봉사동기에 정(+)의 영향을 미치며, 변혁적리더십과 학습지향성, 자기효능감은 공공봉사동기를 매개로 적극행정에 정(+)의 영향을 미치는 것으로 나타났다. 다만 채용제도는 자기효능감과 공공봉사동기와의 관계에서만 조절변수로서 유의한 영향을, 직급은 자기효능감과 공공봉사동기와의 관계와 공공봉사동기와 적극행정과의 관계에서 조절변수로서 유의한 영향을 미치는 것으로 나타났다. 본 연구결과로 정부 인사행정 운영 측면에서 다음과 같은 정책적 시사점을 도출할 수 있다. 먼저, 공직 내 변혁적리더십이 발휘될 수 있는 환경 조성이 필요하다. 또한, 학습지향성과 자기효능감을 제고하기 위해 상시 학습제도의 개편, 공무원 학습조직의 활성화, 개별학습자 맞춤형 컨텐츠 제공이 필요하다. 그리고 공공봉사동기가 적극행정에 미치는 영향력을 고려하여 공공봉사동기 제고방안을 개발할 필요가 있으며, 특히 채용유형과 직급에 따라 달라지는 공무원의 행태를 적극적으로 인사관리에 포섭하여 전략적으로 활용할 필요가 있다. This study was intended to analyze the relationship between transformational leadership in public sector and active administration of public officials in order to strengthen the active administration of public officials in a situation where the role of government and public officials is urgently needed nationwide, such as COVID-19. Specifically, it was intended to study the impact of transformational leadership on the active administration of public officials through the medium of public officials" behavior (learning orientation, self-efficacy, and public service motivation). It was also intended to present practical implications to the government"s personnel strategy by verifying the impact of the recruitment system and rank in relation to transformational leadership, learning orientation, self-efficacy and public service motivation, and the relationship between public service motivation and active administration. According to the research results, transformational leadership has positive influence on learning orientation, self-efficacy and public service motivation respectively, learning orientation and self-efficacy have positive influence on public service motivation, and public service motivation has positive influence on active administration. In addition, transformational leadership has positive influence on public service motivation through each medium of learning orientation and self-efficacy, and transformational leadership, learning orientation, and self-efficacy have positive influence on active administration through public service motivation. However, it has been shown that the recruitment system has a significant effect as a moderator variable only in the relationship between self-efficacy and public service motivation, and that the grade has a significant influence as a moderator variable in the relationship between self-efficacy and public service motivation and active administration. The results of this study can produce the following policy implications in terms of the operation of government personnel administration. First of all, it is necessary to create an environment where transformational leadership in public sector can be exercised. In addition, in order to enhance learning orientation and self-efficacy, it is necessary to reorganize the permanent learning system, revitalize the learning organization of public officials, and provide customized contents for individual learners. In addition, it is necessary to develop measures to enhance public service motivation in consideration of the influence of public service motivation on active administration, and in particular, it is necessary to actively engage in personnel management and strategically utilize public officials" behavior that varies depending on their types of recruitment and grade.

본 연구에서는 국내 사례분석을 비롯하여, 주요 OECD국가의 청년정책 동향 및 정부조직･기능체계 현황을 살펴보며 주요 시사점을 도출하고 이를 바탕으로 우리나라 청년정책 거버넌스의 개선방안을 제시하고자 한다. 이를 위해 2장에서는 청년정책의 유형화, 청년조직의 유형화, 청년정책 거버넌스의 유형화를 통해 우리나라 청년정책 기능수행체계 및 거버넌스 현황분석을 진행한다. 3장에서는 해외 사례분석 및 국외 청년정책 거버넌스 사례를 분석을 통해 우리나라 청년정책의 현 위치 파악 및 시사점을 제시하고자 한다. 이어서 4장에서는 청년단체, 학계 전문가 등을 대상으로 한 초점집단인터뷰(FGI) 분석을 진행한다. 이를 통해 보다 질적이고 심도 있는 개선안 도출이 가능할 것으로 기대한다. 마지막 5장에서는 위의 내용을 종합하여 청년정책 플랫폼 거버넌스 개선방안을 청년정책, 청년정책 전담조직 개편, 청년정책 거버넌스의 세 가지 관점에서 구조화하여 제시한다. 본 연구는 청년정책, 청년조직 개편 및 신설, 청년거버넌스 개선 등에 대한 새로운 통합적 접근방식을 사용하여 청년정책 거버넌스 개념을 확립하고 청년정책 제도 개선방안을 도출한다는 점에서 의의가 있다. This study seeks to draw major implications by examining trends in youth policy and government organizations as well as functional systems in major OECD countries, including case studies in Korea, and to suggest ways to improve youth policy governance in Korea. To this end, Chapter 2 analyzes the current status of youth policy performance and governance in Korea through the classification of youth policies, the types of youth organizations, and the types of youth policy governance. Chapter 3 tries to identify the current status of Korea s youth policy and suggest implications by analyzing overseas case studies and overseas youth policy governance cases. In Chapter 4, focused group interview (FGI) analyses of youth group practitioners and academic experts are conducted. Through this, it is expected that it will be possible to derive more qualitative and in-depth improvement plans. In the last chapter, the above contents are synthesized and the measures to improve the governance of the youth policy platform are presented in a structured way from three perspectives: youth policy, youth policy reorganization, and youth policy governance. This study is meaningful in that it establishes the concept of youth policy governance, draws up measures to improve the youth policy system using new integrated and multi-dimensional approaches, and explore an effective way to restructure youth organizations and agencies as well as improve youth policy governance system.

이영식(Young-Sik Lee):김성엽(Sung-Yeop Kim):김은영(Eun-Young Kim),나 철(Chul Na) 한국중독정신의학회 2001 중독정신의학 Vol.5 No.1

cohol related problems are common in psychiatric field, but the concerns about alcohol induced neuropathy have been relatively lower than other alcohol related problems. We experienced a 25 year-old alcohol withdrawal delirium patient who had severe alcohol induced neuropathy complaining of severe pain on both extremities and not walking. He also had a abnormal electromyographic finding. Although his pain was not ameliorated by the typical usual analgesics such as amitriptyline & carbamazepine, adding mexiletine was remarkably effective for the pain without major side effects. The follow-up of electromyography was no change but patient’s pain was still reduced after 1 month. This case indicated that we psychiatrists should pay more attentions to alcohol induced neuropathy and the treatment of related pain in psychiatric backgrounds.
