In this study, we examined the market and certification system of industrial products in detail. In addition, we also examined the recognition of corporate employees related to certification and the requirements and status of improvement of certification system for corporate employees responding to changes in the certification market. Finally, based on the opinions of the enterprise workers on the certification, I proposed the direction of the certification market and the direction of certification system. The results of this study can be summarized as follows. First, it is necessary to strengthen the role of system cooperation and cooperation between related organizations in order to upgrade the certification of industrial products. In addition to efforts by certification bodies to improve the certification system, improvement of quality of certification examiners, strengthening of after-certification of certified products such as marketing research, improvement and awareness of consumers and corporate employees about certification, and education on certification for consumers and company workers need. Specifically, it is necessary to shorten the KS certification follow-up cycle and to conduct the examination more strictly in order to maintain the quality recognized not only in domestic market but also overseas market and to improve the reliability of KS certification. In addition, it is necessary to examine the measures to reinforce after-sales management in order to spread the employment continuity and quality control technology of the quality control person in the enterprise. Second, it is important to operate a certification system that can meet complex and diverse market, society, and consumer needs. It should be changed to a KS certification policy that reflects technology and industry trends such as sustainable certification system that reflects diversity of society members, certification system that reflects technological advancement and change of consumption market, and increase of fusion combined industry. In the end, it is essential that information exchange related to domestic and overseas certification, information accumulation, related experts, and organic cooperation with stakeholders are essential. Thirdly, it should be a win - win certification system that focuses on corporate and consumer trust and benefits. In particular, it is necessary to pay attention to the fact that the duplicate certification items between the statutory certifications increase and duplicate tests on the same items double the burden of time and cost. The test results should be mutually recognized for the duplicated items between the certifications, and the efficient certification system should reflect the requirements and satisfaction of the certification system of the corporation. 본 연구에서는 공산품 인증시장과 인증제도에 대해 구체적으로 살펴보았다. 또한, 인증관련 기업 근로자의 인식, 인증시장 변화에 대응하는 기업 근로자의 인증제도 개선에 대한 요구 및 현황을 살펴보았다. 끝으로 인증에 대한 기업 근로자들의 의견을 토대로 공산품 인증 시장의 방향 및 인증제도의 방향에 대해 제언하였다. 본 연구의 결과를 정리․종합하면 다음과 같다. 첫째, 공산품 인증의 경쟁력 강화를 위해 여러 정부기관들의 공조와 협력은 필수적 조건이라고 하겠다. 인증제도 개선을 위한 인증심사원의 능력과 자질 함양, 시판품조사 등 인증제품 사후관리 강화, 인증에 대한 소비자와 기업 근로자의 인식개선 및 홍보, 소비자 및 기업근로자 대상 인증 관련 교육 등이 필요하다. 구체적으로 국내 시장 뿐만이 아닌 해외시장에서도 인정받는 품질을 유지하고 KS 인증의 신뢰성을 향상시키기 위해 KS 인증 사후관리 주기를 단축하고 심사를 보다 엄격히 수행할 필요가 있다. 또한 기업 내부적으로도 품질관리 담당자의 고용 연속성, 품질관리기술의 보급․확산을 위하여 사후관리 강화 방안의 검토가 필요하다. 둘째, 복잡하고 다양해져가는 시장과 사회 및 소비자의 요구를 충족시킬 수 있는 인증제도 운영이 중요하다. 사회구성원의 다양성을 반영하는 지속가능한 인증제도, 기술고도화 및 소비시장의 변화를 반영하는 인증제도, 융복합 산업의 증가와 같은 기술 및 산업 트렌드를 반영하는 KS인증정책으로 변화해야 한다. 결국 국내외 인증관련 정보교류 및 정보축적, 관련 전문가, 이해당사자들과의 유기적 협력이 필수적이라고 하겠다. 셋째, 공산품 인증기관의 인증목표가 기업과 소비자 신뢰와 혜택에 초점을 두는 상생적 인증제도가 되어야 겠다. 특히 법정 인증간 중복인증 품목이 증가하고 동일품목에 대한 중복시험으로 기업은 시간과 비용을 이중으로 부담하고 있는 것에 주목할 필요가 있다. 인증 간 중복되는 품목에 대해 시험결과가 상호 인정, 효율적인 인증제도 운영 등으로 기업의 인증제도에 대한 요구 및 만족도를 반영해야 한다.

Background Throughout the body. Dendritic Cells (DCs) capture the antigens, migrate to draining lymphoid organs and mature to present the processed antigens to naive T cells to generate the effector cytotoxic T cells (CTLs) or helper T cells. The granulocyte-macrophage colony stimulating factor (GM-CSF) and tumor necrosis factor-α(TNF-α) cooperate in vitro generation of DCs from Periperal Blood Stem Cells(PBSCs). Interleukin-4 (IL-4) is an another important factor in promoting DCs outgrowth and expression of CD1a with costimulatory molecules and in blocking monocytic differentiation. The aim of this study was induction of differentiation and maturation of dendritic cells from PBSCs in patient with stomach cancer. Methods The CD34+ PBSCs were obtained from the patients with stomach cancer and divided the samples into 6 groups. Flt-3 Ligand (FL) (F group), GM-CSF (G group), IL-4 (I group), TNF-α(T group), GM-CSF and IL-4(GI group), FL, GM-CSF, IL-4 and TNF-α(FGIT group) were added to X-VIVO culturing media. The cells were cultured for 2 weeks, then. examined the morphology of and functions the cells with phase contrast and fluorescence microscopes. Results The generated cells with FL, GM-CSF, IL-4 and TNF-α showed typical morphology of DCs including multiple dendrites and profuse cytoplasm. The cells stained positively with CD1a, CD83 and CD86, FL, GM-CSF, IL-4 and TNF-α. Conclusion Large quantities of mature DCs from PBSCs in a patient with stomach cancer was possible using FL, GM-CSF, IL-4 and TNF-α. Further studies are needed with various types of diseases and culture environments.
