Food labelling is the primary means of communication between the producer and purchaser and plays an important role in consumer's choice of food. Food labelling applying to livestock products, such as meat products (ham, sausage etc.), milk products(milk, fermented milk, butter and cheese etc.) and egg Products is regulated by 'Livestock Products Labelling Standard', National Veterinary Research & Quarantine Service (NVRQS) Notification. This study presents the principles of Korean milk products labelling provision and its recent revision to prevent consumer from misunderstanding and facilitate fair trade practices in market and also keep consistencies with international and relative national regulations. This study also suggests milk products labelling policy direction in the future.

The purpose of this study was to find a suitable standard height of the lavatory in public spaces through the review of relevant regulations, questionnaire survey, lab works, and experiment to measure lavatory heights. The results of the study were as follows: First, the heights of the current public lavatory were ranged from 68cm to 89cm, and the heights to the faucet were from 71cm to 91cm. The recent lavatory was more likely to be higher in heights. Secondly, the suitable height for public lavatory was ranged from 55% to 65% of the heights of the participants put on shoes. Thirdly, 90cm lavatory in height was considered to be more suitable to use for the majority than was 83cm lavatory. Fourth, the author suggest that the suitable y(lavatory height)=77.818 + 0.117x(put on shoes heights). This study suggested that adopting 95% range, the most suitable height of public lavatory is more than 90cm high for the people whose heights are more than 150cm.

In Korea, the regulation is MOLIT Notice 2018-290, Guidance for Approval of Synthetic Flight Trainer as Flight Simulator and Flight Training Device. The FAA (Federal Aviation Administration) categorizes FSTD (Flight Simulation Training Device) into FFS (Full Flight Simulator) and FTD (Flight Training Device), according to its level. Additional categories for regulation are airplane and helicopter, depending on the type of aircraft. In this study, the objective tests for the handling quality of the FAA and Korean regulations were compared and analyzed. In QPS (Qualification Performance Standard), related test titles, flight conditions, and tolerance limits were analyzed for the handling quality. Based on this study, recommendations on amendments to the regulation was presented.

This study is to draw thermal property data during long-term aging, by testing the thermal conductivity of building insulation materials in Korea. The thermal resistance of extruded insulation within 3 days from manufacture performed well over the KS Standard. After 50 to 110 days, however, the thermal performance had deteriorated to the level of the KS standard. Eventually, after 4,000 days, the insulation performance had deteriorated to about 25.4~41.8% of the initial performance. Therefore, this research will be utilized as a reference for thermal properties during long-term aging, in order to improve standards and regulations related to building insulation materials.

My questionaire survey revealed that even those experts that engage in architectural design did not precisely understand much of the regulations concerning ground-level. In terms of restricting the size of the building area, the generous policy of excluding balconies and basements from the calculation of building size actually causes problems. As far as the right to sunshine is concerned, the weighted average ground-level is determined to be the ground-level standard of the neighboring plot when the neighboring plot is a sloping bare ground. When the difference of heights is over 3 meters, it would be appropriate to assess the weighted ground-level standard every 3 meters.

In order to establish a criteria of solid particle separation performance test on marine centrifugal purifier at factory acceptance test, an investigation had been done on criteria of test standards, regulations and test specifications of purifier manufactures. KS V 7836, fuel oil and lubricating oil purifiers for marine use-centrifugal type, the criteria of solid particle separation is studied in the point of reality, restricts and analysis method. It is proposed that a reasonable criteria and analysis method should be adopted, and the current criteria shall be revised to adequate levels considering reasonable basis and industrial technology levels. Also, the test analysis conceptions, separation efficiency method and particle size restriction method, are reviewed to fulfil separation performance test for marine centrifugal purifiers.

This paper aims to point out the problems and solutions of soil fertility enhancement in Korean organic farming which does not harmonize with internationally recognized standard of organic agriculture such as Basic Standard of IFOAM, EU regulations, and guidelines of FAO/WHO codex alimentarius. The necessity of rotation, legume, green manure to enhance the soil fertility or organic farming system was discussed, and the reasons why salt accumulation including nitrate and phosphate in the rooted soil profiles was frequently occurred in Korean organic farmer's field also discussed. Soil testing for correct handling of organic fertilization was introduced to void the salt accumulation just applying the huge amount of organic fertilizer year to year to reach a maximum crop yield. In the conclusion it was suggested for Korean organic agriculture to make an effort to coincide it's regulation with internationally recognized standards for organic farming.

Safety of hydrogen handling facilities is needed as supply of hydrogen cars has been expanded recently. In this study, the adequacy of safety regulations of hydrogen handling facilities and the risk of damage with hydrogen leakage were studied. The range of explosion hazard location of the hydrogen filling plant was investigated using the computational fluid dynamics (CFD) method, Explosive hazardous area is influenced by leakage type, hole size and sectional area. When the conditions of KS standard are applied, range explosive hazardous area is expanded 7.05 m, maximum. It is about 7 times larger than exceptional standard of hydrogen station. Meanwhile, distance from leakage point to 25% LEL of hydrogen is investigated 1.6 m. Considering the shape of charging hose, regulation of hydrogen station is appropriate.

Optimal engine control is needed to cope with the global environmental regulations that are globally enforced. For optimum engine control, the electronic throttle control system (ETCS) is a prerequisite. Automotive makers are having an effect on reducing emissions and improving fuel economy by applying ETCS which is designed to secure stability. The ETCS controls the output of the throttle valve by passing the output value of the accelerator position sensor (APS) to the engine control unit (ECU). In this study, the authors investigated the safety standards of domestic and overseas accelerator control system and tried to understand how the air flow control affects the engine output by replacing the throttle. The authors suggest an improvement proposal of safety standard based on the result of driving evaluation by various modes.

Nowadays many two-wheeled motorcycles are used in leisure and express delivery industries. But studies of the electromagentic compatibility on motorcycles have seldom been performed and published. This paper has studied the electromagnetic safety of motorcycles considering international and domestic regulations and standards. Also, a series of experiments have been performed to evaluate the level of electromagnetic compatibility of commercially available motorcycles. As a result, detailed experimental procedures are proposed to secure the electromagnetic safety and can be used to confirm or revise the Korea Motor Vehicle Safety Standards.
