Purpose: The purpose of this study is to investigate how much continuous investment in human capital contributes to increasing labor productivity at not only individual companies but also at the national level, and causes fundamental as well as increases for labor-management conflicts. The current research aimed to empirically demonstrate the importance of human capital investment and furthermore, based on the effect of human resource investment on labor productivity, also re-examine the role of the Labor Commission as well. Research design, data, and methodology: This study was conducted by the Korea Information Service-Financial Accounting System (KIS-FAS) using representative panel data operated by countries to measure whether long-term investment in corporate human resources affects labor productivity. Results: Two distinctive summarized results of the analysis in the Korea Credit Ratings data showed that there was a high positive correlation between corporate human resource investment and economic performance for a ten-year period from 2009 to 2018. Conclusions: The present study concluded that the role of the labor committee should be effectively formed by the labor as a mediation agency and that the role of the mediation committee members should focus more on how to strengthen the human resources management of the union.

The small modular sodium-cooled fast reactor (SMSFR) is an important component of Generation-IV reactors. The objective of this work is to improve the reactivity control in SMSFR by using innovative systems, including burnable poisons and optimized control rods. SMSFR with MOX fuel usually exhibits high burnup reactivity loss that leads to high excess reactivity and potential fuel melting in control rod withdrawal (CRW) accidents, which becomes an important constraint on the safety and economic efficiency of SMSFR. This work applies two types of burnable poisons in a SMSFR to reduce the excess reactivity. The first one homogenously loads minor actinides in the fuel. The second one combines absorber and moderators in specific assemblies. The influence of burnable poisons on the core characteristics is discussed and integrated into the analysis of CRW accidents. The results show that burnable poisons improve the safety performance of the core in a significant way. Burnable poisons also lessen the demand for the number, absorption ability, and insertion depth of control rods. Two optimized control rod designs with rare earth oxides (Eu₂O₃ and Gd₂O₃) and moderators are compared to the conventional design with natural boron carbide (B₄C). The optimized designs show improved neutronic and safety performance.

Over the years, probabilistic risk assessment (PRA) research activities conducted at the U.S. Nuclear Regulatory Commission (NRC) have played an essential role in support of the agency's move towards risk-informed regulation. These research activities have provided the technical basis for NRC's regulatory activities in key areas; provided PRA methods, tools, and data enabling the agency to meet future challenges; supported the implementation of NRC's 1995 PRA Policy Statement by assessing key sources of risk; and supported the development of necessary technical and human resources supporting NRC's risk-informed activities. PRA research aimed at improving the NRC's understanding of risk can positively affect the agency's regulatory activities, as evidenced by three case studies involving research on fire PRA, human reliability analysis (HRA), and pressurized thermal shock (PTS) PRA. These case studies also show that such research can take a considerable amount of time, and that the incorporation of research results into regulatory practice can take even longer. The need for sustained effort and appropriate lead time is an important consideration in the development of a PRA research program aimed at helping the agency address key sources of risk for current and potential future facilities.

With the development of sequencing technology, there is a need for technology to predict the function of the protein sequence. Enzyme Commission (EC) numbers are becoming markers that distinguish the function of the sequence. In particular, many researchers are researching various methods of predicting the EC numbers of protein sequences based on deep learning. However, as studies using various methods exist, a problem arises, in which the exact prediction result of the sequence is unknown. To solve this problem, this paper proposes an All Enzyme Commission (AEC) algorithm. The proposed AEC is an algorithm that executes various prediction methods and integrates the results when predicting sequences. This algorithm uses duplicates to give more weights when duplicate values are obtained from multiple methods. The largest value, among the final prediction result values for each method to which the weight is applied, is the final prediction result. Moreover, for the convenience of researchers, the proposed algorithm is provided through the AllEC web services. They can use the algorithms regardless of the operating systems, installation, or operating environment.

Ballasting and deballasting of shipping vessels in foreign ports have been reported worldwide as a vector of introduction of non-native aquatic plants and animals. Recently, attention has turned to ballast water as a factor in the global increase of harmful algal blooms (HABs). Many species of microalgae, including harmful dinoflagellate species, can remain viable for months in dormant benthic stages (cysts) in ballast sediments. Over a period of four years, we surveyed ballast water and sediment of ships docked in two ports of Tampa Bay, Florida, USA. Sampling conditions encountered while sampling ballast water and sediments were vastly different between vessels. Since no single sample collection protocol could be applied, existing methods for sampling ballast were modified and new methods created to reduce time and labor necessary for the collection of high-quality, qualitative samples. Five methods were refined or developed, including one that allowed for a directed intake of water and sediments. From 63 samples, 1,633 dinoflagellate cysts and cyst-like cells were recovered. A native, cyst-forming, harmful dinoflagellate, Alexandrium balechii (Steidinger) F. J. R. Taylor, was collected, isolated, and cultured from the same vessel six months apart, indicating that ships exchanging ballast water in Tampa Bay have the potential to transport HAB species to other ports with similar ecologies, exposing them to non-native, potentially toxic blooms.

Fascioliasis is a foodborne zoonotic parasitic disease. We report 4 cases occurring in the same family, in whom diagnosis of acute fascioliasis was established after series of tests. One case was hospitalized with fever, eosinophilia, and hepatic lesions. MRI showed hypodense changes in both liver lobes. The remaining 3 cases presented with the symptom of stomachache only. Stool analysis was positive for Fasciola eggs in 2 adult patients. The immunological test and molecular identification of eggs were confirmed at the National Institute of Parasitic Diseases, Chinese Center for Disease Control and Prevention, Shanghai, China. The results of serological detection were positive in all the 4 patients. DNA sequencing of PCR products of the eggs demonstrated 100% homology with ITS and cox1 of Fasciola hepatica. The conditions of the patients were not improved by broad-spectrum anti-parasitic drugs until administration of triclabendazole.

본 논문은 2008년 6월~2011년 11월 기간 동안 우리나라 주식형 펀드의 자료를 이용하여 소프트달러(위탁매매수수료)와 펀드 특성 사이의 관계 및 위탁매매수수료와 투자수익률 사이의 관계에 대한 분석을 수행하였다. 분석 결과, 운용보수 및 판매보수는 위탁매매수수료와 음(-)의 관계를 가지는 것으로 확인되었는데, 이는 투자자가 상대적으로 명확하게 인지할 수 있는 운용보수 및 판매보수 수준을 높이기보다는 숨겨진 비용인 위탁매매수수료를 통해 간접적으로 보상이 이루어짐을 시사한다. 한편, 위탁매매수수료와 펀드성과 사이의 관계를 살펴본 결과, 위탁매매수수료가 높을수록 현재의 성과와 음(-)의 관계를 가지며, 단기적으로 미래의 성과를 제고하는 데 기여하지 못하는 것으로 확인되었다. 이러한 분석 결과는 투자자와 운용사의 이해상충의 완화와 대리인 문제의 효과적인 통제를 위한 제도 정비의 필요성을 시사하는 것으로 생각된다.

최근 지방자치단체들은 지역발전전략의 일환으로 영상로케이션산업을 채택하고 영상로케이션 유치를 위해 지역영상위원회를 설립하고 있다. 경북의 영상로케이션 유치는 문경의 KBS왕건세트장 건립을 시작으로 증가하기 시작하여 다수의 영화 및 드라마가 촬영되었으며, 2006년 경북영상위원회를 설립하였다. 그러나 경북의 영상로케이션은 단순히 촬영을 경북지역에서 한다는 것뿐 촬영관련 기업의 참여는 미진하다. 뿐만 아니라 경북의 영화산업은 소비위주의 구조를 지니고 있어 제작기업의 역량이 매우 부족한 실정이다. 따라서 경북의 영상로케이션산업을 육성하기 위해 경북영상위원회는 전통적인 영상위원회의 역할을 넘어서는 보다 넓은 의미의 역할을 수행할 필요가 있다. 왜냐하면. 경북의 아름답고 풍부한 자연 및 인문자원과 영상위원회의 전통적인 지원서비스만으로는 경쟁력을 갖기 어렵기 때문이다. 따라서 경북영상위원회는 경북영상로케이션산업의 핵심거점기관으로써 영상위원회의 전통적 역할인 로케이션 관련 서비스 제공, 영상로케이션에 필요한 로케이션 관련 시설 및 업체, 제작인력, 지역주민(자원봉사자, 엑스트라 등) 등에 대한 DB 구축 및 이력 축적, 그리고 이들 관련 기관간 협력네트워크 구축 이외에도 전문인력 양성 및 기업 유치, 영상친화적 제도적 기반 구축, 지역내 협력분위기 창출, 영상관광 촉진, 지역영상문화 창달 등의 역할을 수행해야 할 것이다.
