For maintaining adequate psychometric properties when reducing the number of items from an instrument, item level psychometrics is crucial. Strategies such as low item correlation or factor loadings, using classical test theory, have traditionally been advocated. The purpose of this study is to describe the development of a new short form assessing the impact of low back pain on physical activity. Rasch measurement model has been applied to the International Classification of Functioning, Disability and Health Activity Measure (ICF-AM). One hundred and one individuals with low back pain aged 19-89 years (mean age: $48.1{\pm}17.3$) who live in the community were participated in the study. Twenty-seven items of lifting/carrying construct of the ICF-AM were analyzed. Ten items were selected from the construct to create a short form. Item elimination criteria include: 1) high or low mean square (out of the range: .6-1.4 for the fit statistics), 2) similar item calibrations to adjacent items, 3) person separation value, and item-person map for potential gap in person ability continuum. All 10 items of the short form fit to the Rasch model except one item (i.e., carrying toddler on back). Despite its high infit and outfit statistics (1.90/2.17), the item had to be reinstated due to potential gaps at the upper extreme of person ability level. The short form had a slightly better spread of person ability continuum compared to the entire set of item. The created short form separated individuals with low back pain into nearly 4 groups, while the entire set of items separated the individuals into 6 groups. The findings prompted multidimensional models for better explanation of the lifting/carrying domain. The item level psychometrics based on the Rasch model can be useful in developing short forms with rationally retained items.

Purpose: The purpose of this study was to examine the mediating effect of self-perception on the relationship between body image and depressive symptoms in middle school adolescents. Methods: This study performed a pathway analysis with a sample of 284 adolescents recruited from three middle schools. Self-reported questionnaires consisted of items regarding body image, self-perception, and depressive symptoms. Results: Body image, self-perception, and depressive symptoms showed a significant correlation. Self-perception was directly affected by body image and depressive symptoms were not affected by body image. The mediating effect of self-perception on body image's impact on depressive symptoms was confirmed. Self-perception had a significant indirect effect on depressive symptoms, which means that self-perception has a full mediating effect on body image's impact on depressive symptoms. Conclusion: The effect of body image on depressive symptoms was fully mediated by self-perception in early adolescents. It suggests that self-perception needs to be considered when providing nursing interventions for adolescents.

Purpose: The small-scale environmental impact assessment system in Korea was introduced and implemented in August 2000, but it has a problem that it cannot guarantee implementation due to the large proportion of qualitative reduction measures for each evaluation item. Therefore, when preparing a small-scale environmental impact assessment, research was conducted on how to improve the existing simple listing-type reduction measures and qualitative evaluation standards to quantitative reduction measures and evaluation standards reflecting regional characteristics. Research design, data and methodology: The small-scale environmental impact assessment system in Korea was introduced and implemented in August 2000, but it has a problem that it cannot guarantee implementation due to the large proportion of qualitative reduction measures for each evaluation item. Therefore, when preparing a small-scale environmental impact assessment, research was conducted on how to improve the existing simple listing-type reduction measures and qualitative evaluation standards to quantitative reduction measures and evaluation standards reflecting regional characteristics. Results: As a result of the analysis of qualitative and quantitative factors, the arithmetic sum of the qualitative factors of the total six projects is 160, accounting for 80% of the total number of reduction measures, and the quantitative factors are 40, accounting for 20%. Among them, the number of qualitative reduction measures reached 97.4% for animal and plant items, and more than 90% for air quality, noise and vibration, and eco-friendly resource circulation items. Conclusions: Therefore, it is necessary to avoid establishing qualitative reduction measures and set quantitative measures as the basis, but to specify the specifications, size, and installation location related to the reduction measures, and to calculate the numerical reduction efficiency.

This study was conducted to evaluate the variation characteristics of influent and effluent quality from sewage treatment facilities using activated sludge processes and to assess the impact caused by discharge of treated sewage on the receiving water Monthly data of five water quality items (BOD, COD, SS, T-N, T-P) were used to understand the water quality at three sewage treatment plants in Seoul for five years from 1999 to 2003. Concentration differences of water quality parameters were observed between upstream and downstream site at the sewage treatment plant outfall to investigate the impact of discharge in Tan stream and Han river basin. 1. Due to the effect of continuous improvement in sewer system, the concentrations of influent went on increasing generally. 2. Effluent concentrations of BOD, COD and SS showed the trend of a little decreasing, but the trend of increasing in T-N and T-P. 3. In Tan stream basin, the impact of sewage treatment plant discharge was not observed directly, because concentration of discharge was lower than stream water's. But discharges from sewage treatment plants affected water quality at downstream site in Han river, concentration of T-P especially.

현행 환경영향평가 내 건강영향평가는 단일 물질별 기준초과 여부를 평가하고 적정 저감방안을 수립하도록 시행된다. 이에 따라 일부 개발 대상사업의 경우, 위해성평가의 모든 물질이 기준을 만족하지만 노출농도가 기준에 매우 근사한 경우가 존재한다. 하지만 여기서 모든 물질들의 동시 노출을 고려한다면 건강영향은 단일 물질별 관리보다 상당히 크게 발생할 여지가 있다. 실제로 수용체에 노출되는 건강영향을 파악하기 위해 배출물질의 통합평가 방법론의 구체화 및 개선방안 마련이 필요하다. 본 논문은 해외 선진사례 및 국내외 문헌고찰을 통해 누적위해성평가 및 위해성의 통합기법에 대한 개념을 정의하고, 산업단지 개발 시 다물질에 대한 건강영향을 고려한 누적위해성평가 활용을 위한 방법론을 제안하였다. 제안된 방법론을 통해 산업단지에 배출되는 유해중금속 4종(Ni, Cr⁶⁺, Cd, As)에 대한 통합지표를 산출하였으며, 과거 10년(2011~2020년) 간 수행된 산업단지 개발사업에 대한 사례적용을 통해 활용성을 확보하였다.

The Alcoholics Anonymous(AA) program has been known to be effective in many countries in helping alcoholics to stop drinking and to change their attitudes, beliefs, and behaviors. In this study, we examined AA activities among Korean AA members and measured the self-evaluated physical, social, and mental changes following the entry into the AA program. Out of identified 300 AA members who were attending 18 different AA group meetings at the time of the survey, 207 completed the self-administered questionnaire(response rate of 69.0%). T-test and ANOVA were used to compare the scores of physica(4-items), social(4-items), and menta(10-items) changes according to the level of AA activities. The proportion of the respondents who practiced the 11th step (meditation) or the 12th step (take alcoholics to a meeting after carrying messages) on the regular basis was 66.6% and 37.2%, respectively. The average time spent in meditation per week was $4.8{\pm}5.47$ hours. The length of participation in AA meetings has significantly positive impact on the average score of changes in all the 3 health states; physical(p<.01), social(p<.05), and mental states(p<.01). Also, practicing the 11th step was significantly associated with improvement of social(p<.01) and mental(p<.05), while practicing the 12th step improved only mental states(p<.01). Our findings demonstrated that not only the length of participation in AA meetings but also the practice of regular meditation(11th step) and taking alcoholics to an AA meeting after carrying messages(12th step) are very important for AA members, and lead to great positive changes in physical, social, and mental states following entry into the AA program.

Purpose: This study aimed to evaluate the validity and reliability of the Korean version of Menopause-Specific Quality of Life (MENQOL). Methods: The MENQOL was translated into Korean according to algorithm of linguistic validation process. A total of 308 menopausal women were recruited and assessed using the Korean version of MENQOL (MENQOL-K), the World Health Organization Quality of Life Brief Version (WHOQOL-BREF), and Center for Epidemiological Studies Depression Scale (CES-D-K). In estimating reliability, internal consistency reliability coefficients were calculated. Validity was evaluated through criterion validity and construct validity with confirmatory factor analyses using SPSS 23.0 and AMOS 25.0 software. Results: In item analyses, the "increased facial hair" symptom was excluded because of the low contribution of MENQOL-K. The confirmatory factor analysis supported good fit and reliable scores for MENQOL-K model, and the four-factor structure was validated (χ²=553.28, p<.001, NC=1.84, RMSEA=.05, AGIF=.85, AIC=765.28). The MENQOL-K consists of 28 items in 4 domains, including vasomotor (3 items), psychosocial (7 items), physical (15 items), and sexual subscales (3 items). There was an acceptable criterion validity with moderately significant correlation between MENQOL-K and WHOQOL-BREF. The Cronbach's α for the 4 subsacles ranged from .80 to .93. Conclusion: The MENQOL-K is a valid and reliable scale to measure condition-specific quality of life for perimenopausal and postmenopausal women. It can be used to assess the impact of menopausal symptoms on the quality of life of Korean women in clinical trials.
