Objectives: This study assessed the status of domestic industrial hygiene laboratories using data from on-site investigation for revision of quality control systems in 2012-2013. Methods: The target laboratories were 60 industrial hygiene laboratories chosen by random selection and nationwide distribution which had participated in on-site investigations for revision of quality control systems from March 2012 to August 2013. The investigation was performed on-site following standard quality control procedures. The score between each group was compared using Mann-Whitney and Kruskal-Wallis tests, and the correlation between analytical career, sex, academic major of analyst and score of analytical performance was expressed as Spearman`s rank correlation coefficient. Results: The assessment revealed that the items to be improved, in sequence, were effort at staff training(score 65.5), ability to calculate data(score 73.4), establishment of internal quality control guidelines(score 75.7), laboratory facilities(score 77.1), degree of understanding and skill at gas chromatography(score 77.1). Analysis performance showed a positive correlation with career of analyst(r=0.56, p<0.01). Conclusions: The practice of on-site investigation for quality control systems showed the current status of industrial hygiene laboratories in the first trial. There were many laboratories which needed improvement and development of analytical systems. This assessment can provide information for the systematic operation and improvement of facilities at each laboratory. Further practice of this investigation will lead to a proficiency testing and accreditation system for autonomous quality control as is the practice in many countries, rather than mandatory practice by legal regulation.

정신장애인의 재활과정에서 회복이 먼저인가, 사회적응이 먼저인가?

신정이(Jung Yi Shin),이선혜(Sun Hae Lee) 한국정신건강사회복지학회 2010 정신보건과 사회사업 Vol.34 No.-

본 연구에서는 정신장애인의 재활성과와 그에 영향을 미치는 요인들 간의 구조적 관계를 실증적으로 파악하기 위해 사회적응, 회복, 기술, 사회적 지지, 낙인의 5가지 잠재요인을 도출하여 이들의 구조적 관계에 대한 경쟁모형을 수립하고, 모형검증을 통해 최적 모형을 찾고자 했다. 이를 위해 전국 지역사회 정신보건기관 62개소에서 서비스 이용자 753명을 대상으로 일상·사회기술, 사회적 지지, 낙인, 회복, 사회적응 등에 관한 설문을 실시했다. 분석결과, 정신장애인의 기술과 사회적 지지, 낙인의 3가지 요인이 회복을 매개로 사회적응에 영향을 미치는 `회복매개모형`이 적합한 것으로 나타났는데, 그 중 기술역량은 가장 큰 영향력을 가진 요인으로 회복에 가장 크고 직접적인 영향력이 있을 뿐만 아니라 사회적응에도 가장 큰 간접적 영향력을 갖고 있었다. 사회적 지지는 회복과 사회적응에 직접적인 영향력은 없었으나 회복과 사회적응에는 간접적인 영향력을 갖고 있었으며, 낙인은 회복과 사회적응에 유의한 직·간접적 영향력을 갖지 못했다. 이러한 결과를 토대로 재활성과 이해에 대한 시사점을 논의했으며 재활성과 향상을 위한 개입전략을 제안했다. The purpose of this study was to empirically examine the structural relationship between the factors which play key roles in influencing the rehabilitation of persons with severe mental disorders. Once five latent factors were derived, two competing models were established and analyzed in an attempt to determine the better model for understanding the process in which social adjustment and recovery take place. The research data was gathered by collecting self-administered questionnaires from 753 service users recruited from sixty-two mental health organizations in South Korea. The questionnaire inquired about service recipients` skills, social support, stigma, recovery, social adjustment, as well as mental health status and socio-demographic profile. The results showed that the "Recovery-Mediated Model", which hypothesized that the individuals` skills, social support and stigma exercise the largest influence over social adjustment, was adopted as the better model. Specifically, the skills were the key factor which exercised the most direct influence on the individuals` recovery, while also having the most indirect influence on their social adjustment. Social support did not have any significant direct influence on recovery and social adjustment, but had an indirect influence on them. On the other hand, stigma did not play a noticeable role in recovery and social adjustment either directly or indirectly. Several intervention strategies for improving mental health outcomes were presented.

Removal efficiency and potential of N and P by Salix gracilistyla Miq. are determined in continuous flow tanks as a function of hydraulic retention time(HRT, days) and nutrient concentration (NC). Results show that the removal efficiency was longer HRT and lower nutrient solution. And also removal potential was higher at shorter HRT and higher nutrient concentration, and the regression equations were estimated. Mean above ground biomass of Salix gracilistyla Miq. in the middle reaches of Suip stream was 4880.81g/㎡, and estimated removal by this vegetation from biomass and estimated equation above were 0.49∼15.49 NH_4-N ㎏/day, 5.83∼405.39 NO_3-N ㎏/day, 7.57∼23.22 PO_4-P ㎏/day in Suip stream, respectively when HRT was 0.59∼5.21, inflow concentration was 0.05∼0.4, ㎎/L NH_4-N, 1.42∼11.36 ㎎/L NO_3-N, 0.1∼0.27 ㎎/L PO_4-P. According to this study, it is concluded that Salix gracilistyla Miq. are contribute by their high biomass and for water quality improvement of stream through nutrient removal potential.

Uptakes of N and P by Phragmites japonica Steudel. are dtermined in continuous flow tanks as a function of hydraulic retention time(HRT, days) and nutrient concentration(NC). Results show that the uptake was higher at shorter HRT and higher nutrient concentration, and the regression equations were estimated. Mean above ground biomass of Phragmites japonica in the middle reaches of Sagimak stream was 335.92g/㎡, and estimated uptake by this vegetation were 7.31∼20.15 HN_4∼N, 31.15∼95.84 NO_3∼N, and 4.09∼11.48 PO_4-P ㎎/㎡/day in Sagimak stream, respectively when HRT was 1∼5 days. According to this study, it is concluded that Phragmites japonica Steudel. are suitable for water quality improvement of stream through nutrient uptake at short HRT and high concentration.

Our study introduces a novel method for early detection of hearing impairment by automatically analyzing speech patterns in word recognition tests. Using an audio dataset based on the Korean standard monosyllabic word list, we segmented audio into instances to extract phoneme features. Employing a semi-supervised learning framework, we identified normal speech patterns solely from normal data. During inference time, we computed anomaly scores based on instance-level similarity to pinpoint deviations from normal speech, achieving an 85.08% accuracy rate in identifying hearing impairment. Additionally, we successfully localized abnormal phonemes within speech, demonstrating the efficacy of our approach.

Hearing loss is closely related to depression, cognitive impairment, and dementia. Therefore, early diagnosis and treatment of hearing loss can prevent these conditions. However, there has been no research on classifying hearing loss based solely on speech data. In this paper, we conducted a study on classifying hearing loss using speech data from normal individuals and those with hearing loss over the age of 50. We found that the combination of Mel-spectrogram and VGGish DNN model perform 86% accuracy in 2-class classification.
