To develop ready-to-eat (RTE) style Korean traditional Galbi-jjim, the optimal conditions for sous-vide cooking and cookchill preparation and the sensory properties of the cooked products were investigated. During heating, the meat core temperatures reached $85^{\circ}C$ within 30 min and 45 min when a water bath and combination oven were used, respectively. Chilling to $3^{\circ}C$ within 45 min was conducted to meet the standards for microbiological safety set by the UK Department of Health and Social Security (DHSS) Guideline. Galbi-jjim that was vacuum-cooked in a water bath was much more tender than that of Galbi-jjim prepared using the cook-chill method, but had no difference in any reheating methods. The average sensory scores of juiciness and the overall acceptance of Galbi-jjim were significantly higher when water bath cooking was used, and there were no differences in reheating methods. In conclusion, the serial methods of sous-vide processing and rapid chilling can be applied to produce RTE traditional Galbi-jjim, and this can be conducted while meeting the standards specified in safety guidelines.

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.

현 도로설계기준은 설계속도에 기반하여 선형설계에 관한 지침을 제시하고 있으며, 이는 설계속도가 도로 공용 후에 운전자의 주행 속도와 거의 동일할 것임을 전제하고 있다. 도로 평면 곡선부의 설계도 주어진 설계속도에 따라 운전자가 쾌적성을 유지한 채 통과할 수 있는 최소곡선반경을 기준으로 제시하고 있다. 그러나 쾌적성에 기초한 횡방향 미끄럼마찰계수는 실제 습윤노면에서 관측되는 물리적인 횡방향 미끄럼마찰계수보다 낮기 때문에 기준에 제시된 곡선반경은 최소의 의미보다는 권장 값으로 보는 것이 합리적이다. 아울러, 최소곡선반경보다 여유로운 설계 값을 선호하는 실무관행으로 도로 공용 후 운전자의 주행속도는 설계속도를 상회하여 설계속도가 주행속도를 대표하지 못하는 결과를 초래하고, 결과적으로 현 설계기준의 주요전제를 위반하게 될 것으로 본다. 이러한 연구 가정을 검토하기 위해 지방부 도로에서 노면 미끄럼 마찰계수와 운전자의 주행속도를 조사하였다. 연구결과로, 쾌적성에 기반한 미끄럼 마찰계수와 물리적인 미끄럼마찰계수와의 차이에 따른 안전여유를 정량적으로 제시했고, 안전여유 및 설계관행에 따른 여유로운 설계로 인해 설계속도와 주행속도 간에 괴리가 발생함을 제시했다. 이를 토대로, 현 설계속도 기반의 선형설계는 최소기준과 더불어 설계속도와 주행속도 사이의 괴리를 최소화할 수 있는 선형 설계 관리 방안이 마련될 필요가 있다.

This study was intended to find methods of fire extinguishing system designs that can improve the equipment's usability. In this study, the fire suppression experiment through fire extinguishers and the data drawn through the experiment were analyzed, and then the guideline for the improvement of designs was presented. The procedure is as follows. A fire suppression experiment with the use of fire extinguishers was done by 43 average adults. The whole process of the fire suppression was videotaped, and then captured major scenes were analyzed with the use of RULA, a human engineering measurement tool. The analyzed data were divided into 4 steps, and then the guideline for design improvement was presented. The summary of the study is as follows. Step 1, Fire extinguisher distance step. To reduce overload occurring at the process of holding fire extinguishers suddenly, wheels are attached to the body of extinguishers, or pedestals are installed. Step 2, Fire extinguisher transportation step. The length of hose is extended, or fire fighting water is sprayed far, so that overload of legs occurring at the process of travel can be reduced. In addition, the weight of fire extinguisher shouldn't be over 2 kg. Step 3, Safety pin removal stage. Safety pins should be applied with button type, so that excessive posture of lower limbs and excessive twisting of wrists won't happen during safety pin removal process. Besides, safety pins should be designed for easy identification and operation. Step 4, Fire extinguishing agent spraying step. To reduce overload occurring at sudden spraying of fire fighting water, pressure should be increased gradually until high pressure. With the above study results applied to existing fire extinguisher design, it may contribute to reducing any fire damage.

According to the statistics publication of KOSHA, more than half of serious accidents at the construction sites were related to the temporary works and/or the temporary structures such as scaffoldings, shores, earth retaining walls, etc. The structural failures are occurred because of the overload acting on the structures or lack of performance of the one or more members of the structures. For the prevention of the collapse accidents relating to the temporary structures at the construction sites, we have to control construction processes not to occur the overload and also to control the performance and quality of each member of the temporary structures. MOLIT has amended the "Construction Technology Promotion Act" on Jan. 7th, 2015 to ensure the structural safety of the temporary structures. According to the Act, the designers of the construction design projects should check the structural integrity of the structures including the temporary structures and the construction companies have to let 'the Relative Professionals' confirm the structural integrity of temporary structures, the shores(${\geq}5m$ high) and the scaffolds(${\geq}31m$ high), before construction. Also, MOLIT has amended the "Regulation for Construction Technology Promotion Act" on Jul. 4th, 2016 for quality management and testing of temporary equipments. According th this regulation, the construction companies and supervisors should manage and test the temporary equipments before using them. In this paper, the standard drawings of the shores(< 5 m high) and the scaffolds(< 31 m high) and the amended "Business Guideline for Quality Management of Construction Work" are presented. As the result of this study, MOLIT noticed the amended "Business Guideline for Quality Management of Construction Work" on Jul. 1st, 2017.
