이 연구의 목적은 일-교육훈련-자격이 연계될 수 있도록 노동부의 국가직업능력표준을 국가차원에서 개발·운영·관리될 수 있는 제도화 방안을 마련하는데 있었다. 연구목적 달성을 위해 문헌고찰 및 내용분석, 포커스그룹인터뷰를 실시하였고, 연구결과의 타당성 확보를 위해 전문가협의회 및 공청회를 실시하였다. 국가직업능력표준 제도화는 표준의 실용화를 제고할 수 있도록 관련용어 정의, 총괄기구, 표준개발 및 승인, 표준 활용에 관한 인프라 구축에 필요한 사항이 규정되도록 관계 법령을 정비하는 것이다. 표준 제도화를 위해 다음과 같은 사항이 관계 법령에 명시되도록 해야 한다. ① 표준 제도화를 위해 직업, 직업능력, 직무, 표준 등을 관련법에 정의해야 한다. ② 국가직업능력표준 관련 부처 및 다양한 이해당사자의 참여를 기반으로 한 국가직업능력표준 사업 전담 조직을 설치하고, 표준사업에 대한 자문과 심의를 담당할 수 있는 위원회를 구축한다. ③ 다양한 산업분야 단체가 표준개발의 주체가 될 수 있도록 지원하고, 표준의 수준 설정을 통해 직종 내 수직적 경력개발을 촉진하며, 개발된 표준에 대한 지속적인 관리와 현장적합성을 승인하는 체제를 구축해야 한다. ④ 국가직업능력표준은 산업현장에서는 인력을 채용하고 관리하는 기준으로, 교육훈련에서는 교육과정을 개발하고 교과목 및 교재를 개발하며 현 교육과정을 평가하는 기준으로, 자격체계와는 표준의 자격화, 새로운 자격설계, 자격의 출제기준으로 활용될 수 있도록 지원해야 한다. 이를 위해 국가기술자격법, 근로자직업능력개발법, 산업인력공단법 등 관계 법령을 개정하거나 국가직업능력표준에 관한 특별법을 제정할 필요가 있다. 한편, 국가직업능력표준 제도화 단계에 따른 구체적인 추진과제와 이를 실현하기 위한 정책적 제언을 제시하였다. The purpose of this study was to develop the institutionalization that NOS(National Occupational Standard) was developed, operated and managed for linking with work, training and qualification. To achieve the purpose, literature reviews, contents analysis and focus group interview were conducted, and experts council and a public hearing were executed. The institutionalization is the legislation consolidation to regulate details related infra construction as follows for improving utilization of NOS. ① It should be defined occupation, occupational competency, job, standards and so forth on the related laws. ② A organization which take exclusive charge with and a council which consult and deliberate on NOS projects should be established through the cooperation between stakeholder and government organization. ③ It should be supported that various industrial parties including SHRDC are the main body for development of NOS, promoted vertical career development by occupation through establishing level of NOS, and established system that manage continually and approve practical application of NOS. ④ It should be supported that NOS is used as a criterion for recruiting and managing workforce, a criterion for developing and evaluating curriculum and educational materials in training, having qualification for itself, designing for new qualification, and a criterion for setting questions for a qualifying examination. To improve utilization of NOS, It need to be consolidated the related laws including National Technical Qualifications Act and Workers' Vocational Competency Development Act or to be enacted a special law on NOS. Moreover, this study suggested action plan according to the stages of institutionalization, and political proposal for effective actualization of action plan.

<P><B>Abstract</B></P> <P>Incorporating bioactive molecules into synthetic ceramic scaffolds is challenging. In this study, to enhance bone regeneration, a magnesium phosphate (MgP) ceramic scaffold was incorporated with a novel indene compound, KR-34893. KR-34893 induced the deposition of minerals and expression of osteoblast marker genes in primary human bone marrow mesenchymal stem cells (BMSCs) and a mouse osteoblastic MC3T3-E1 cell line. Analysis of the mode of action showed that KR-34893 induced the phosphorylation of MAPK/extracellular signal-regulated kinase and extracellular signal-regulated kinase, and subsequently the expression of bone morphogenetic protein 7, accompanied by SMAD1/5/8 phosphorylation. Accordingly, KR-34893 was incorporated into an MgP scaffold prepared by 3D printing at room temperature, followed by cement reaction. KR-34893-incorporated MgP (KR-MgP) induced the expression of osteoblast differentiation marker genes <I>in vitro</I>. In a rat calvaria defect model, KR-MgP scaffolds enhanced bone regeneration and increased bone volume compared with MgP scaffolds, as assessed by micro-computed tomography and histological analyses. In conclusion, we developed a method for producing osteoinductive MgP scaffolds incorporating a bioactive organic compound, without high temperature sintering. The KR-MgP scaffolds enhanced osteoblast activation <I>in vitro</I> and bone regeneration <I>in vivo</I>.</P>

<P><B>Abstract</B></P> <P>Since elevated osteoclast formation and/or activity by inhibitory responses against pathogens leads to diverse osteolytic bone diseases including periodontitis, inhibition of osteoclast differentiation and bone resorption has been a primary therapeutic strategy. In this study, we investigated the therapeutic potential of a novel benzamide-linked molecule, OCLI-070, for preventing alveolar bone loss in mice with ligature-induced experimental periodontitis. OCLI-070 inhibited osteoclast formation by acting on both early and late stages of differentiation, and attenuated the induction of nuclear factor of activated T-cells, cytoplasmic 1 (NFATc1) and the expression of osteoclast-specific genes. In addition, OCLI-070 significantly suppressed the formation of actin rings and resorption pits. Analysis of the inhibitory action of OCLI-070 showed that it markedly suppressed receptor activator of nuclear factor-κB ligand (RANKL)-induced extracellular signal-regulated kinase (ERK) and NF-κB signaling cascades. Moreover, OCLI-070 prevented ligature-induced alveolar bone erosion in mice by suppressing osteoclast formation. These findings demonstrate that OCLI-070 attenuated osteoclast differentiation and function as well as ligature-induced bone erosion by inhibiting RANKL-mediated ERK and NF-κB signaling pathways.</P> <P><B>Highlights</B></P> <P> <UL> <LI> OCLI-070 inhibits osteoclast differentiation from bone marrow-derived macrophages. </LI> <LI> OCLI-070 significantly attenuates the bone-resorbing activity. </LI> <LI> OCLI-070 suppresses RANKL-induced MEK-ERK and NF-κB pathways. </LI> <LI> OCLI-070 protects ligature-induced alveolar bone loss. </LI> </UL> </P>
Consideration on the Relationship Between Security and Safeguards

SMR, which has recently been in the spotlight, has several advantages. However, it poses additional challenges in the areas of new design, digitalization, security, safety and safeguards. Among them, security refers to measures to protect nuclear materials and facilities from unauthorized access, theft, or destruction. Safeguards refer to measures to prevent the spread of nuclear weapons. The relationship between security and safeguards is complex and constantly evolving. In general, security measures are designed to protect nuclear materials and facilities from physical attack, while safeguards are designed to track and monitor the movement of nuclear materials and prevent them from being used to create nuclear weapons. In some areas security and safeguards work in complementary ways, and in other areas they conflict. But ultimately, finding a balance is what is effective and efficient. In conclusion, although the security and safeguards of SMRs have different key objectives, they are closely related and must be implemented comprehensively and consistently to ensure the safety of nuclear facilities, the public, and the environment. In this paper, we investigate how the safety and safeguards of SMR are currently being researched and analyze what difficulties there are when assuming that they are operated as a single interface.
