2022년 7월 21일부터 시행된「수산부산물 재활용 촉진에 관한 법률(이하, 수산부산물법)」은 수산부산물을 친환경적· 위생적으로 처리하고, 재활용을 촉진함으로써 수산 자원을 효율적으로 이용하기 위하여 제정되었다. 그리고 「수산부산 물의 배출량 산정 방법과 이물질 등의 제거기준 고시」에서는 수산부산물 분리배출의무자에게 수산부산물에 붙어 있는 잔존 육질 등의 이물질 함유량을 3% 이하(무게기준)로 배출하도록 하고 있으나, 구체적인 이물질 함유량 시험법의 부재 로 현장에서는 혼란스러워하는 실정이다. 이에 본 연구에서는 다양한 분야의 유사 시험법을 검토 후 이들 부산물(껍데기) 의 이물질 함유량 시험방법을 제안하고자 하였다. 본 연구에서는 대상 이물질의 종류 또는 범위, 채취하는 시료 수와 양, 시료채취방법, 건조 등 전처리 방법, 분석방법, 이물질 함유량의 계산방법 등을 제안하였다.

「The Act on Promotion of Recycling of Fishery By-Products」, which came into effect on July 21, 2022, was enacted to efficiently use fishery resources by processing fishery by-products in an eco-friendly and hygienic manner and promoting recycling. And, the「Notice on Methods for Determining Emission of Fishery By-products and Standards for Removal of Foreign Substances, etc.」requires those the responsibility for separate discharge of fishery by-products below 3% or less of the content of foreign substances. However, there is confusion in the field due to the lack of content testing methods. Accordingly, this study reviewed similar test methods in various fields and proposed a test method for the foreign matter content of these by-products (i.e. shells). In this study, the test method for shellfish by-products includes the type or range of target foreign substances, the number and amount of samples, the sampling method, pretreatment methods such as drying, analysis methods, and calculation methods for foreign matter content.

본 연구에서는 「수산부산물법」에서 규정하고 있는 이물질 함유량을 산정할 때 필요한 강열에 의한 껍데기 자체 구성분의 감량(K), 육안 선별 이물질과 강열감량에 의한 유기성 이물질을 구한 후 산정식에 의하여 이물질 함유량을 구하였다. 특히 K 값을 구할 때 강열 온도의 영향, 최종 이물질 함유량을 구 할 때 굴 껍데기의 적치 기간에 따른 영향 등에 관하여 검토를 수행하였다. 강열온도에 따른 강열감량 시험 결과, 강열온도가 높아질수록 이물질로서 함유 된 유기성분 뿐만 아니라 껍데기 자체 구성분의 감량도 증가함을 확인하였다. 그리고 K 값을 구하기 위한 20회 반복 실험 결과, K 값을 4.00%로 제안하였 다. 적치 기간에 따른 굴 껍데기에서의 이물질 함유량은 적치 기간이 긴 시료가 적치 기간이 짧은 시료보다 낮아 배출기준을 만족하는 것으로 나타났다. 따 라서 굴 껍데기의 배출기준을 만족시키기 위해서는 굴 수확 후 2~3개월 정도의 안정화 시간이 필요함을 알 수 있었다.

In this study, the total foreign matter content stipulated in the 「Fisheries By-Products Act」 was determined using the loss of the shell's own components by ignition (K), hand-picked foreign matter, and organic foreign matter by ignition loss. In particular, a review was conducted on the influence of ignition temperature when calculating the K value and the influence of the storage period of oyster shells when calculating the final foreign matter content. As a result of the loss on ignition test according to the ignition temperature, it was confirmed that the higher the ignition temperature, the greater the loss of not only the organic components contained as foreign matter but also the components of the shell itself. And as a result of 20 repeated experiments to obtain the K value, the K value was suggested to be 4.00%. The content of foreign matter in oyster shells according to the storage period was lower in samples with a longer period than in samples with a short period, indicating that storage period has a significant impact on removal of organic foreign matter. Therefore, it was found that in order to meet the discharge regulation standards for oyster shells, a storage period for stabilization of about 2 to 3 months is needed after the oyster harvest.

전세계적으로 재난에 의한 피해가 급증하면서 인명피해를 줄이기 위한 장비에 대한 기술개발이 필요한 실정이다. 이에 소방안전 및 119구조․구급기술연구개발사업의 지원으로 “인명구조용 소방대원 근력지원장치 개발(2015 ~ 2018)” 과제를 통하여 재난환경 및 재난 대응 시나리오를 고려한 리프팅 성능(양중하중 100 kg 이상, 양중높이 1 m 이상, 양중거리 60 cm 이상, 양중속도 0.2 m/s 이상)을 만족하는 장비를 개발 중에 있다. 본 연구는 장치의 유용성을 판단하기 위해 양중성능 및 내환경 시험법을 제안하였고, 양중성능시험의 동역학 해석을 통해 근력지원장치의 상세사양을 분석 및 검증하였다. 본 연구를 통하여 제안한 시험 방법은 근력지원장치의 안정적인 성능 구현여부를 평가하는데 실용적으로 적용할 수 있을 것으로 판단된다.

As the damage caused by disasters increases rapidly around the world, it is necessary to develop the technology for equipment to reduce human injury. Therefore in the support of fire safety and 119 rescue and rescue technology research and development project, in the "Development of a power assist device for a fireman to rescue humans(2015 ~ 2018)" for life saving restoration, we are developing equipment that satisfies the lifting performance considering the disaster environment and the disaster response scenario(Amount of load over 100 kg, height of over 1 m, height over middle 60 cm, speed over 0.2 m/s). In this study, we propose a lifting performance and environmental test method to evaluate the usefulness of the power-assisted device and analyze and verify detailed specifications of the device through dynamics analysis of the lifting performance test. This study suggests that the proposed test method can be applied practically to evaluate whether a stable performance of a power-assisted device is achieved.

The biopharmaceutical drugs which are produced by recombinant DNA technology or new biotechnology and used for the treatment of human diseases have developed since 1980s, and successfully introduced in drug market. Some of them became blockbuster drugs and have entered in the category of major drugs having a grand market size. In this study, the registry of the biopharmaceutical drugs in official compendium including Korean Pharmacopoeia was investigated by comparing foreign pharmacopoeias such as US Pharmacopoeia, European Pharmacopoeia and Japanese Pharmacopoeia. In Korea, biologic drugs have been regulated by the official notification[The Criteria and Test of Biologics\, and the recombinant pharmaceuticals has been also regulated in this notification. However, the market expansion of drugs in this category requires the official registry in the official compendium. In this article, the necessity of registration of some selected biopharmaceuticals in the official compendium is addressed, and the consideration points in general notices, general rules of preparations, general tests and general information of Korean Pharmacopoeia is suggested. In addition, the registration of biosimilar drugs in official compendium, for example in Korean Pharmaceutical Codex, is also proposed, for taking action on the market entrance of biosimilar drugs following the expiration of patent of oldest biopharmaceutical drugs. This will be helpful in more effective management and regulation of biopharmaceutical drugs and in harmonization with international requirements.

Objective To identify factors affecting test results of the quiet standing balance evaluation conducted by posturography and to investigate the standardized method by comparing results according to feet width. Method Th e study cohort consisted of 100 healthy individuals. We assessed the quiet standing balance of subjects by using 3 diff erent methods: standing on a force plate with feet width the same as shoulder width (test 1); with feet width the same as half the shoulder width (test 2); with feet width determined by the subject’s comfort (test 3). Subjects underwent each test with their eyes open and closed for 30 seconds each time. Parameters for measuring standing balance included the mean mediolateral and anteroposterior extent, speed, and the velocity moment of center of pressure (COP) movement. Results All parameters showed better results when the subject’s eyes were open rather than closed, and the mean AP extent and speed increased as the age of the subjects increased (p<0.01). However, there was no signifi cant correlation between height and the study parameters, and no differences between men and women. Mean mediolateral extent and speed were signifi cantly longer and faster in test 1 compared with tests 2 and 3 (p<0.01). Th e results of test 2 were better than the results of test 3, but the diff erence was not statistically signifi cant. Conclusion COP movements increased with age and when subjects closed their eyes in an evaluation of quiet standing balance conducted by posturography. Gender and height did not aff ect results of the test. We suggest that an appropriate method for conducting posturography is to have the subject stand on a force plate with their feet width the same as half the shoulder width, because this posture provided relatively accurate balance capacity.

At the same time, the mechanism of tire/road noise is analyzed, which provides a experimental basis for tire noise reduction.

One of the major applications of REBCO coated conductor (CC) tapes is in superconducting magnets or coils that are designed for high magnet fields. For such applications, the CC tapes were exposed to a high level of stresses which includes uniaxial tensile or transverse compressive stresses resulting from a large magnetic field. Thus, CC tapes should endure such mechanical load or deformation that can influence their electromechanical performance during manufacturing, cool-down, and operation. It has been reported that the main cause of critical current (Ic) degradation in CC tapes utilized in coil windings for superconducting magnets was the delamination due to transversely applied stresses. In most high-magnetic-field applications, the operating limits of the CC tapes will likely be imposed by the electromechanical properties together with its Ic dependence on temperature and magnetic field. In this study, we examined the influence of the transverse compressive stress on the Ic degradation behaviors in various commercially available CC tapes which is important for magnet design Four differently processed REBCO CC tapes were adopted to examine their Ic degradation behaviors under transverse compression using an anvil test method and a newly developed instantaneous Ic measurement system. As a result, all REBCO CC tapes adopted showed robustness against transverse compressive stresses for REBCO coils, notably at transverse compressive stresses until 250 MPa. When the applied stress further increased, different Ic degradation behaviors were observed depending on the sample. Among them, the one that was fabricated by the IBAD/MOCVD process showed the highest compressive stress tolerance.

Game development costs a lot of money. Thus, in terms of cost-saving, game companies produce prototypes and undergo several tests and modifications during the development period. In this paper, we proposed a brainwave signal analysis system and linked it with the game to measure the player's emotion through brainwave analysis experiment and tried to solve these problems. The brainwave signal analysis system proposed in this paper is capable of various applications according to various development situations, such as the progress of the game, events, etc. in obtaining simple figures over time by linking games, and collecting the tester's responses according to development intentions, so there will have to be continuous additional research.

Background: For a verification of newly-developed neutron absorbers, one of guidelines on the qualification and acceptance of neutron absorbers is the neutron attenuation test. However, this approach can cause a problem for the qualifications that it cannot distinguish how the neutron attenuates from materials. Materials and Methods: In this study, an estimation method of neutron absorption performances for materials is proposed to detect both direct penetration and back-scattering neutrons. For the verification of the proposed method, MCNP simulations with the experimental system designed in this study were pursued using the polyethylene, iron, normal glass and the vitrified form. Results and Discussion: The results show that it can easily test neutron absorption ability using single absorber model. Also, from simulation results of single absorber and double absorbers model, it is verified that the proposed method can evaluate not only the direct thermal neutrons passing through materials, but also the scattered neutrons reflected to the materials. Therefore, the neutron absorption performances can be accurately estimated using the proposed method comparing with the conventional neutron attenuation test. Conclusion: It is expected that the proposed method can contribute to increase the reliability of the performance of neutron absorbers.

학교 실내공기질 측정에 적용되고 있는 현장직독식 방법과 공정시험기준을 적용하여 실제 학교 3개 교실에서 PM10, PM2.5, 이산화탄소, 폼알데하이드를 측정하고 그 결과를 비교하였다. 이산화탄소의 경우 두 방법에 의한 측정결과가 유사 하였으나 미세먼지와 폼알데하이드에서는 현장직독식 방법의 결과가 공정시험기준에 따른 결과와 차이를 나타내었다. 따라서 현장직독식 측정은 학교에서 자체 수행하는 주기적인 환경관리에 활용하고, 높은 신뢰성이 요구되는 법적 기준 충족 여부에 대해서는 공정시험기준에 따른 측정이 바람직하다고 판단된다.

In order to confirm the validity of the on-site direct-reading method (OSDR) for measuring indoor air quality in school, we evaluated PM10, PM2.5, carbon dioxide, and formaldehyde in three classrooms using two OSDR equipments and Korean standard method for indoor air quality test (SM), and compared the results. For the carbon dioxide concentration, similar results to SM could be obtained with OSDR. However, the concentrations of fine particulate matters and formaldehyde determined by an OSDR equipment showed a significant difference from the results of SM. Therefore, it is desirable to use some OSDR only for routinely checking the indoor environment of school, and measurement by SM is required for regular inspection.

P300 숨긴정보검사에서는 조사대상자가 거짓을 말하고 있는지 판단하기 위하여 관련자극의 P300 진폭이 무관련자극의 P300 진폭보다 통계적으로 유의하게 더 큰지를 평가한다. 구체적인 통계적 방법으로 독립표본 t 검증 또는 부트스트랩 방법을 사용할 수 있다. Rosenfeld와 Soskins, Bosh, Ryan(2004)은 “개인 내에서 관련자극과 무관련자극의 P300 평균을 비교하는데 사용하기에는 t 검증이 너무 둔감하다.”면서 부트스트랩 방법을 사용하였다. 본 연구의 목적은 P300 숨긴정보검사에서 t 검증의 검증력이 부트스트랩 방법보다 더 낮은지 평가하는 것이다. 이를 위하여 39명의 실험참가자로부터 측정한 뇌파자료를 이용하여 Monte Carlo 연구를 수행하였다. 연구결과, t 검증과 백분위를 이용한 부트스트랩 방법의 1 종 오류율은 서로 비슷하였으며, 백분위를 이용한 부트스트랩 방법의 검증력이 t 검증의 검증력보다 약간 더 높았다. 두 검증 방법의 1 종 오류율은 모두 유의수준보다 낮은 값을 보였으며, 검증력은 이론적인 t 검증의 검증력보다 약간 낮은 값을 보였다. 반면에 표준오차를 이용한 부트스트랩 방법의 1 종 오류율과 검증력은 이론적인 t 검증의 1 종 오류율 및 검증력과 비슷한 값을 보였으며, t 검증의 검증력보다 실험조건에 따라 .012 ~ .081 더 높았다.

In P300-based concealed information test (P300 CIT), it evaluates whether the P300 amplitude for the probe is significantly greater than that of the irrelevant to determine if the suspect is telling a lie. An independent sample t-test or a bootstrap method can be used as a statistical test to make that decision. Rosenfeld et al. (2004) used the bootstrap method, claiming that “t tests on single sweeps are too insensitive to use to compare mean probe and irrelevant P300s within individuals” and their method has been accepted to date. The purpose of the study is to evaluate whether the power of t-test is lower than that of the bootstrap method in the P300 CIT. The Monte Carlo study was conducted by using EEG collected from 39 participants. The results showed that the type I error rates of the t-test and the percentile bootstrap method were similar and the power of the percentile bootstrap method was slightly higher than that of the t-test. The type I error rates of the t-test and the percentile bootstrap method were slightly lower than the significance level and the powers of the two tests were also slightly lower than that of the theoretical t-test. On the other hand, the type I error rate and power of the standard error Bootstrap method were the same as those of the theoretical t-test and its power was .012 ~ .081 higher than that of t-test depending on experimental conditions.

The selection of TRT and its interpretation method are important to design an economical geothermal heat pump system because heat exchange rate of a borehole heat exchanger system highly depends on effective thermal conductivity of ground.Two thermal response tests (TRTs) are performed in a 200 m long vertical closed-loop borehole heat exchanger, and thermal conductivities are estimated with a conventional method using the line source theory, and the Horner plot method. The Horner plot method is applied to recovered circulation fluid temperatures during fluid circulation after power shut-in, and recovered ground temperatures were measured by a fiber optic temperature sensing method. The estimated thermal conductivity using the conventional method is 2.75W/m/K, and that using the Horner plot method is 2.87 W/m/K. The average effective thermal conductivity using the Horner plot method with fiber optic temperature sensing data is 2.88 W/m/K and the average core sample thermal conductivity measured in a lab is 2.90 W/m/K. By comparison of each results with core thermal conductivity data, three different interpretation methods show reliable results.

In order to respond to environmental pollution, developed countries, including Korea, have begun to conduct research to utilize hydrogen energy. For mass transfer of hydrogen energy, storage as liquid hydrogen is advantageous, and in this case, the volume can be reduced to 1/800. As such, the transportation technology of liquefied hydrogen for ships is expected to be needed in the near future, but there is no commercialized method yet. This study is a study on the technology to test the performance of the components constituting the membrane type storage container in a cryogenic environment as a preparation for the above. It is a study to find a way to respond by analyzing in advance the problems that may occur during the shear test of adhesives. Through this study, the limitations of ISO4587 were analyzed, and in order to cope with this, the specimen was supplemented so that fracture occurred in the adhesive, not the adhesive gripper, by using stainless steel, a low-temperature steel, to reinforce the thickness. Based on this, shear evaluation was performed under conditions lowered to minus 243℃, and it was confirmed that the breaking strength was higher at cryogenic temperatures.

최근에 장시간 근무로 인한 대중교통 운전자들의 부족한 휴식과 수면, 통증, 정신적 스트레스 등은 피로 누적를 초래하여 대중교통 사고의 주요 원인으로 대두되고 있다. 이에 2016년 산업통상자원부 산업융합촉진 사업의 일환으로 대중교통 운전자용 다중 생체 신호측정 스마트 의류 및 관련 시스템이 개발중에 있으며 본 논문에는 현재 개발중인 스마트웨어러블 의류의 내세탁성능에 대한 성능 시험방법을 제안하고자 한다. 성 능시험 방법은 국내외 생체신호측정 스마트 의류의 care label(취급표시사항)을 통하여 hand wash의 조건으로 세탁을 표시하고 있으나, 1년의 warranty를 위한 시험을 위해서는 오랜기간이 필요하기 때문에, 좀더 가혹한 조건으로 진행하여 시간을 줄이고, 고객의 빠른 시장출시를 지원하도록 시험방법을 제안하였다.

원자력 안전에 대한 국민적 관심이 지속적으로 증가하고 있는 가운데 그동안 비정규직 으로 위탁운영되던 원자력발전소 특수경비원의 정규직화가 추진 중에 있다. 특수경비원은 시설경비하기, 무기 사용하기, 비상사태 대응하기, 출입통제하기 등 상당한 수준의 체력이 요구되는 직무를 수행하는 바, 특수경비원의 정규직화 과정에 있어 이들의 체력검정방안에 대한 논의가 시급한 실정이다. 본 연구에서는 문헌연구를 통해 한국, 미국, 일본 3개국의 경찰, 소방, 군인을 대상으로 한 체력검정방법을 분석하였으며, 이를 통해 기존 특수직종별 체력검정방법의 특징과 장‧ 단점을 고찰하고자 하였다. 이후 전문가 회의를 거쳐 원자력발전소 특수경비원에게 적합한 새로운 체력검정방법을 도출하였다. 또한 본 연구는 개발된 체력검정방법이 현장에 도입될 수 있도록 체력검정결과를 해석 할 수 있는 가이드라인을 제시하고자 하였다. 이를 위해 74명의 피검자를 대상으로 체력 검정을 실시하였으며, 실험결과를 기초로 특수경비원 체력검정종목별 예상기록을 제시하였다.

National interest in nuclear safety continues to increase. One of the policies that the government is pursuing is to change a temporary position to a permanent position for irregular special security guards of Nuclear power plants. At this point in time, it is urgent to discuss the method of their physical fitness test because duties of special security guards such as arrest and self-defense, unarmed defensive tactics, proficiency with semiautomatic rifle, etc, demands a lot of physical fitness. The purpose of this study is to analyze the physical fitness tests of police, firefighters and soldiers in Korea, US and Japan through literature review. After that, a new fitness test method suitable for special security guards of nuclear power plants was derived through expert meetings. This study also suggested a guideline to analyze the fitness test results so that the developed fitness method can be introduced to the field. For this purpose, physical fitness tests were conducted on 74 subjects. Based on the results of the experiment, the expected records of special security guard fitness tests were presented.

본 논문에서는 주거시설의 화재안전성에 대하여 침대매트리스의 방염시험방법 및 시험방법 개선에 관하여 연구하였다. 2018년 화재건수 중 주거시설의 화재가 12,002건이고 주요 가연물 중 침구류가 858건(7.2%)을 차지하고 있어 주거시설 화재 중 두번째로 위험성을 내포하고 있다. 주거시설의 발화장소 중 두 번째로 침실이 1,232건(10.3%)으로 많으며 침대 매트리스 및 침구류의 최초 착화물 및 연소 확대물 통계는 858건으로 보고되어있다. 주거시설 화재의 인명피해가 많이 발생하는 이유로 는 침대 매트리스 등 화재하중이 높은 가연물이 많아 화재가 발생하면 급격한 연소 확대 현상이 나타난다. 또한 화재발생 시간 대가 주로 심야 취침시간이어서 거주자가 화재 발생 사실을 조기에 인지하지 못한다는 심각성을 내포하고 있다. 이러한 화재위 험성을 줄이기 위해 침구류 등의 화재 저항 성능확보가 요구된다. 본 연구는 기존의 방염 관련 시험법에 따른 실험으로는 화재 성상에 대한 정확한 분석이 어려운 점을 고려하여 유럽 등지에서 적용되는 KS ISO 12949 표준 및 미국 상무성의 16 CFR Part 1633 표준에 의한 실물화재시험으로 분석해야 함을 제안하고 방염의 제도 및 시험방법 개선(안)을 제안하였다.
