Measuring the food safety has been focused only on the psychological consumers' recognition of food safety. The actual measurement tool should consist of the evidence-based statistical data to assess the level of national food safety in scientific perspectives. This paper described the development of a concept to measure the food safety of the food chain based on OECD PSR framework. This paper discusses the elaboration of a set of 8 food safety related data issued as statistical data, and which were same weighted. These food safety statistical data (FSDs) were derived as the basis of measuring the variation of food safety during 2013-2019. The values of the primary production indicator (PPI), the processing and manufacturing indicator (PMI), and the distribution and consumption indicator (DCI) are 0.558-0.859, 0.533-0.691, and 0.979-0.982, respectively. The food safety status (FSS) derived from the safety indicator values of each of the three stages is 0.700-0.810. In order to increase the level of food safety, it is necessary to pay attention to PMI and PPI management. In the future, continuously calculating the level of food safety, managing it like the level of psychological safety, and further expanding it to the level of food safety between countries will help establish policies to improve the level of food safety in Korea.

Objectives: The purpose of this study was to provide hospital management diagnosis status and basic data required for the future development of hospital management diagnosis program. Methods: We conducted a questionnaire survey on administrative staff of manager level or over of medical institutions in B metropolitan city. Results: As a result of analyzing the relative influence of the needs by hospital management diagnosis indicator, the effect of financial analysis indicator, patient treatment record indicator and medical revenues indicator were high in the medical institutions with number of beds of 100 beds or over and general hospital level or over both on a hospital level and on an individual level. Conclusions: Since the existing laws or systems are centered on large major hospitals, the management environment is very unfavorable for small and medium hospitals as can be seen from the results of this study. Therefore, the government should improve the transparency and rationality of the hospital management environment in Korea through regulation and system reforms that can be applied to all medical institutions.

This study performed intensive indicators based on a model of economics of education. Trends of childcare in Korea were obtained by producing values developed with statistical data. Results showed that such simple initial indicator values as numbers of children, institutions and teachers have improved. However, intensive indicator values that take demographic and economic conditions into consideration have not reached the same rate of progress as the initial indicator values. In other words, qualitative growth remains at an unsatisfactory level in comparison to quantitative growth and to qualitative growth in members of the Organization for Economics Cooperation and Development (OECD).Thus, financial investment by the government should be expanded in order to reach the desired level of high quality in daycare for children.

This study establishes key success Predictors of internet venture enterprises in Korea. The five factors are derived from the relevant literature and clarified the concept of entrepreneurship, industrial level, enterprise strategy, organizational capability, and resource procurement by distinguishing between its components and determinants. Organizational performance indicators were derived from the previous studies classifying by financial performance indicator and non-financial performance indicator using by recent evaluation method as BSC (Balanced Scorecard). We then examine the impact of critical success factors on the internet venture performance. Hypotheses on five factors of internet venture were tested for 103 organizations. Results indicate that critical success factors may serve as key predictors. Organizational strategy and resource capability was found to be positively influenced on both financial performance indicator and non-financial performance indicator while entrepreneurship, industrial level and organizational capability positively affected only non-financial performance indicator.

The genus-level biotic index of benthic macroinvertebrates (Benthic Macroinvertebrates Genus Index, BMGI) was developed and applicated based on the data collected from 13,347 sampling units of 814 sites from 2010 to 2021 in Korea. Tolerant values of 274 indicator taxa were established by analyzing the relationship between the relative frequency and abundance of indicator taxa and the water quality index considering biochemical oxygen demand (BOD₅), total suspended solids (TSS), and total phosphorus (T-P). BMGI showed a slightly higher correlation with water quality than the species-level biotic index (Benthic Macroinvertebrates Index, BMI) that was developed and applied in Korea. Although the BMGI does not contain species-level information, the reason why BMGI shows higher applicability than BMI seems to be due to the increase in the number of indicator taxa and the decrease in the misidentification of immature aquatic insects. The coefficient of determination in multiple regression with BOD₅, TSS, and TP for BMGI was 0.62 in the long-term averaged data of 814 sites, and the standardized coefficient of BOD₅ was -0.46, TSS was -0.17 and T-P was -0.21, respectively. As a result of the evaluation by BMGI, of the 814 sites, 38% were in good, 25% in fair, and 37% in poor condition.

Indicator PCB의 농도 수준은 2006년에 세계보건기구(WHO) 프로토콜에 따라 수집된 132개의 모유(초유, 출산 후 30일째 모유, 출산 후 60일째 모유)로 분석하였다. Indicator PCBs의 농도는 고분해능 가스크로마토그래피/고분해능 질량분석기를 이용한 동위원소희석법으로 측정되었으며, 이 방법은 국제적 경향을 비교 평가하기 위한 정확하고 정밀한 데이터를 제공한다. 또한, 모든 분석 결과를 토대로 평균일일섭취량(ADIs)이 계산되었다. 총 indicator PCBs의 중앙값은 14 ng/g lipid로, 다른 나라에서 검출된 농도보다 현저하게 낮았으며, PCBs 138, 153, 180은 분석한 지표 이성질체 합의 약 65%를 차지하였다. 가장 기여율이 높은 PCB 153은 총 indicator PCBs 농도와 매우 높은 상관관계를 나타내었다(p<0.001). PCBs 농도는 산모의 아이수가 증가할수록 확연히 감소하였고, 산모의 PCBs 축적과 배출에 있어 출산경력과 수유기간은 중요한 인자로 나타났다. 6개월 모유수유 기간 동안 총 indicator PCBs의 평균일일섭취량의 중앙값은 $0.077{\mu}g/kg{\cdot}bw/day$이었다. 초산부 모유 중 PCB 118의 농도는 1998년에 비해 25~35% 정도 감소하였으며, 이러한 경향은 지속될 것이라는 것을 보여준다.

In the indoor location estimation system, which has recently been actively studied, the received signal strength indicator contains a high level of noise when measuring the signal strength in the range between two nodes consisting of a receiver and a transceiver. To minimize the noise level, this paper proposes an improved adaptive smoothing filter that provides different exponential weights to the current value and previous averaged one of the data that were obtained from the nodes, because the characteristic signal attenuation of the received signal strength indicator generally has a log distribution. The proposed method can effectively decrease the noise level by using a feedback filter that can provide different weights according to the noise level of the obtained data and thus increase the accuracy in the distance and location without an additional filter such as the link quality indicator, which can verify the communication quality state to decrease the range errors in the indoor location recognition using ZigBee based on IEEE 802.15.4. For verifying the performance of the proposed improved adaptive smoothing filter, actual experiments are conducted in three indoor locations of different spatial sections. From the experimental results, it is verified that the proposed technique is superior to other techniques in range measurement.

국가 단위의 자원생산성은 GDP/DMC로 측정한다. 그러나 GDP의 경우 지표 특성상 자원으로부터 발생된 부가가치만을 구분하기 어렵다는 한계가 있다. 이에 본 연구에서는 자원생산성 지표(이하 GDP/DMC) 수식 중 GDP에 에너지 조정계수를 적용(이하 GDPe) 하였다. GDPe 적용 결과, 제조업 비중이 높은 우리나라는 자원사용량 1톤당 평균 1,094.60 USD/ton의 가치를 창출하였으며 OECD 38개 국가 중 4위로 기존 GDP/DMC 대비 10계단 상승하였다. 반면 3차 산업이 전체 GDP의 70%를 차지하는 룩셈부르크는 GDPe 적용 후 자원생산성 순위가 12계단 하락하였다. GDPe/DMC는 산업구조별 에너지 사용량을 고려해 자원에 국한하여 부가가치를 측정하므로 제조업 비중이 높은 국가의 경우 산업특성이 반영되어 자원생산성이 기존보다 상대적으로 높게 나타날 수 있다. GDPe/DMC는 산업구조가 확연히 다른 국가들(에너지/자원집약도가 높은 산업 중심의 국가와 그렇지 않은 국가) 간의 자원생산성 비교 분석을 통한 개선안 도출에 매우 유용하게 활용될 수 있을 것으로 사료된다. 뿐만 아니라 산업구조가 유사한 국가들 간에 자원생산성 비교, 분석을 위해서도 참고지표로써 유용하게 활용될 수 있을 것으로 판단된다.
