In recent years, Zn-Al-Mg alloy galvanized steel sheets have been widely used as coated steel sheets to support social capital in the infrastructure field. A feature of Zn-Al-Mg alloy-coated steel sheets is that they provide a better corrosion protection period than Zn-coated steel sheets. In this study, the corrosion resistance of a new Zn-Al-Mg alloy-coated steel sheet was investigated and compared to that of conventional commercially available coated steel sheets. The investigation confirmed that increasing the Mg concentration in the Zn-Al-Mg-coated steel sheet improved corrosion resistance, which was more than 10 times that of the galvanized steel sheet specified in JIS G 3302. The study findings also confirmed that the corrosion resistance reached more than twice that of the coated steel sheet specified in JIS G 3323. If such galvanized steel sheets are applied to social infrastructures that are exposed to severely corrosive environments, the service life of the infrastructure might be extended.

Purpose: Malnutrition may influence neurocognitive development in children by directly affecting the brain structural development, or indirectly by affecting the children's cognition experience. Malnutrition alters the cell numbers, cell migration, synaptogenesis, and neurotransmission due to inadequate availability of necessary micronutrients to support cell growth. We aimed to analyze neurocognitive development in infants with malnutrition and its association with long chain polyunsaturated fatty acids (LC-PUFA), micronutrients levels and magnetic resonance spectroscopy (MRS) findings. Methods: The study included two groups; group 1, infants with malnutrition (n=24), group 2; healthy infants (n=21). Peripheral blood was obtained from the participants for studying micronutrients and LC-PUFA levels. The neurocognitive development was analyzed by the use of an Ankara Developmental Screening Inventory test. MRS were performed on all infants. Results: All parameters of neurocognitive development and serum calcium ($9.6{\pm}0.9mg/dL$ vs. $10.4{\pm}0.3mg/dL$, p<0.05) and magnesium ($2.02{\pm}0.27mg/dL$ vs. $2.2{\pm}0.14mg/dL$, p<0.05) levels were noted as being low in infants with marked malnutrition. No difference was found in LC-PUFA levels between healthy and malnourished infants. Thalamic choline/creatine levels were significantly high in infants with malnutrition ($1.33{\pm}0.22$ vs. $1.18{\pm}0.22$, p<0.05). Total neurocognitive development in infants was positively correlated with serum calcium levels (p<0.05, r=0.381). Conclusion: Calcium supplementation may improve neurocognitive development in malnourished infants.

To enhance success probability of a system development project, its overall risk level should be minimized through systematically managing schedules, costs, and technical performances. However, Attempts to manage technical performance compared to numerous efforts to control costs and schedules in such projects are deficient. Particularly, a space launch vehicle, a large complex system, development project is much less likely to meet its technical performance objectives due to its technological difficulty, along with schedule delay and cost overrun. The technical performance management (TPM) is a method for tracking and managing technical progress in order to achieve technical performance targets within schedule and budget. In this paper, we investigate applications of the TPM in several space launch vehicle development projects. Then we propose and validate the TPM process to achieve a successful mission in such projects.

The facility diagnosis technique of past subjective judged the technical expert and interpreted stably mainly. The facility the periodical civil official becomes indispensability consequently with the law and the system and objectivity inspection which relates with a this and development of diagnosis technique were necessary. Currently the evaluation elements which relate with an inspection and diagnosis technique depended to the subjectivity of each facility quality, data statistics, diagnosis know-how, various circumstance and the technical expert and the evaluation item came to decide. But the evaluation score distribution of marks of each item depended plentifully in data analysis result and experience. The past method is weak in logically because the objection theoretical background and basis are insufficiency. Consequently in order to apply a data analysis result and an experience logically, it used AHP(Analytic Hierarchy Process) method from this research. It is visible with the fact that the application result reconfirmation and complement process will be necessary the technique which is suitable in the multi facility management. Also it is expected with the fact that the application characteristic from the next relation technique will be excellent.

본 논문에서는 직무발명보상제도가 기업의 기술혁신에 얼마나 도움이 된다고 생각하느냐는 질문에 54.0%가 "많은 도움이 된다", 23%가 "기술개발에 중추적인 역할을 한다"라는 결과였다. 직무발명제도상에서 기술혁신이 발생하여 170개 기업들이 기술개발단계, 138개 기업이 아이디어 형성단계로 나타났다. 기술혁신이 기술개발단계와 아이디어 형성단계에서 집중하게 된 이유는 신제품 개발의 첫 단계인 신제품을 아이디어 창출단계에서는 가장 많은 아이디어를 창출하는데 역점을 두어야 하기 때문에 소비자, 경쟁자, 전문가 등의 다양한 원천에서 아이디어를 수집하면서 발명을 착상하게 된 것과 제품화되었을 때의 잠재적 가치가 평가기준으로 활용한다.

The most important task in acquiring the weapon system is to determine the required performance and to test & evaluate it. The importance of the weapon system by ROC (Required Operational Capability) is not considered, and system development and test evaluation are carried out. In addition, technical incidental performance is tested on the same basis as ROC in the test evaluation and determined according to the result. Development test and evaluation that evaluates technical ability is very important, but development agency is supervised and performed. In this paper, we propose a method to give weights considering the importance of ROC, a technical incidental performance determination and test procedure, and a improvement plan for the development and operational test & evaluation.

Technical Measures includes Measures of Effectiveness(MOEs), Key Performance Parameters(KPPs), Measures of Performance(MOPs) and/or Technical Performance Measures(TPMs). Technical measurement is the set of measurement activities used to provide supplier and/ or acquirer insight into progress in the definition and development of the technical solution, ongoing assessment of the associated risks and issues. This paper describes how technical measures can be applied, using the measurement process described in the previous study and shows the relationship between the various types of technical measures.

Objectives: This study aimed to select items for technical guidelines through the guidelines of the Korean Occupational Safety and Health Agency (KOSHA) for agricultural workplaces. Methods: All 1,308 guidelines provided by KOSHA were reviewed and categorized using a Delphi technique questionnaire on their compatibility and urgency. Results: Among all the KOSHA guidelines, 100 items related to agricultural workplaces were selected. After that, two Delphi questionnaires were conducted and 46 items were finally selected. The average compatibility was calculated as 4.26, and urgency was 2.39. As a result of measuring the content validity of 46 items, six items were identified that were not relevant to agriculture. The final selected items were classified into four categories: Health examination and management, machinery standards, safety and health standard guides, and workplace environment management. Conclusions: The various risk factors at agricultural workplaces should be prevented and managed. It was shown that related technical guidelines or work standard manuals should be prepared. The technical guidelines of KOSHA will be provided as basic categories in the agricultural sector.
