Objective: Cortical Visual Impairment (CVI) is a leading cause of pediatric blindness and the most common form of pediatric visual disability, particularly prevalent among children with cerebral palsy (CP). This systematic review synthesizes the latest research on various interventions for managing CVI, focusing on studies published in the last decade. Design: A systematic review Methods: A comprehensive search was conducted in March 2024 across several databases including MEDLINE, CINAHL, Embase, and Web of Science. Studies were selected based on inclusion criteria set under the PICOSD framework and were limited to those involving human subjects, published in English, and conducted within the past ten years. The selected studies included randomized controlled trials, observational studies, and case reports focusing on rehabilitation, therapy, and surgical interventions for CVI. Results: Out of 221 studies screened, 5 met the inclusion criteria and were reviewed in detail. These studies covered a range of interventions including physiotherapy, sensory integration training, visual training programs, neuromotor rehabilitation, and surgical procedures aimed at improving visual function and overall quality of life for CVI patients. Conclusions: The studies demonstrate the potential benefits of structured, early intervention programs that incorporate family involvement and are tailored to the unique needs of children with CVI. However, there remains a significant need for further research to establish evidence-based practices in this field.

Objectives: Limited information is available on the presence and associated ecological risks of pharmaceutical residues in aquatic environments near pharmaceutical manufacturing areas in Korea. In this study, we investigated the current state of pharmaceutical contamination and its associated ecological risks in streams near a pharmaceutical manufacturing complex. Methods: Seven pharmaceuticals (acetaminophen, clarithromycin, diclofenac, diphenhydramine, ibuprofen, mefenamic acid and roxithromycin) were measured in water samples collected from the streams near a pharmaceutical manufacturing complex. A predicted no-effect concentration (PNEC) was derived using either the assessment factor method or species sensitivity distribution method. In addition, a hazard quotient for each pharmaceutical was calculated by dividing its measured environmental concentration by its PNEC. Results: Samples collected downstream from the wastewater treatment plant (WWTP) had higher concentrations of pharmaceuticals than those collected from the reference site (upstream). Moreover, pharmaceutical concentrations were greater in ambient water than in the final effluent from the WWTP, which suggested that non-point sources were contributing to the contamination of the ambient water environment. Some of the target pharmaceuticals exhibited a hazard quotient >1, indicating that their potential ecological effects on the aquatic environment near the pharmaceutical industrial area should not be ignored. Conclusion: This study demonstrated that the pharmaceutical manufacturing area was contaminated with residual drugs, and that there was a possible non-point source near the WWTP effluent discharge area. The results of this study will aid in the development of management plans for pharmaceuticals, particularly in hotspots such as pharmaceutical industrial sites and their vicinities.

Objectives: This investigation is purposed to evaluate the airborne asbestos concentrations in the public buildings having asbestos containing materials(ACMs) in Seoul. Methods: The Seoul Metropolitan Government carried out an asbestos survey to the city-owned public buildings to identify the level of risk exposure, classified into low, moderate and high risk. To evaluate the airborne concentration of asbestos, 11 sampling sites in ten buildings based on the survey were selected. The air samples from the eleven sites were analyzed by Phase Contrast Microscopy(PCM) and Transmission Electron Microscopy (TEM), and compared the analytical results from the both. Results: 1. The airborne fiber concentrations by PCM were less than the detection limit($7f/mm^2$) in 9(82%) out of 11 sampling sites. The highest concentration was 0.0043 f/cc, but it was below the guideline value for indoor air quality(0.01 f/cc), proposed by the Ministry of Environment, Korea. 2. In two sampling sites, having moderate risk level, the chrysotile was identified and showed it's concentrations of 0.0102 s/cc and 0.0058 s/cc, less than $5{\mu}m$ lengths. 3. The ACMs identified in the two sampling sites were a packing material(65% of chrysotile) in mechanical area and a thermal system insulation(5% of chrysotile) in a boiler room. Having more possibility of asbestos emission in the mechanical area, it would be required to set up and carry out the asbestos management plan. Conclusions: Based on the result of this study, the airborne asbestos concentrations in the public buildings with ACMs were generally lower than the guideline value for indoor air quality. There are widespread concerns about the possible health risk resulting from the presence of airborne asbestos fibers in the public buildings. Most of the previous studies about airborne asbestos analysis in Korea were performed based on PCM method that asbestos and non-asbestos fibers are counted together. In the public and commercial buildings, having ACMs, it is suggested that the asbestos be analyzed by TEM method to identify asbestos due to concerns about asbestos exposure to workers and unspecified people.

1. Introduction Community medicine with the concept of comprehensive medical care and an ideal medical care delivery system not only for an individual or family but for the whole community has emerged. In April 1970, the Presbyterian Medical Center started a hospital based community health service project in order to improve the health of the people in rural areas. Prior to commencing a comprehensive medical care system, a family survey was needed. The major objective of this survey was to obtain information concerning the people and their environment so as to be able to plan and implement a comprehensive medical care program in Soyang-Myun. 2. Survey Method An interview using a family record form was carried out for each household. This family record form was designed to get information about demography, family planning, environmental sanitation and vital statistics. Prior to beginning, the members of the survey team were trained in interviewing techniques for three days. The team consisted of a public health nurse, four nurse-aides, a sanitarian and four health extension workers who are working in our project, The survey was carried out during the period November 1971 to March 1972. 3.

The purpose of this study is to investigate the affecting factors on perception of marriage needs in 20-30s unmarried workers. This study used raw data from the survey on the actual social and economic conditions of the youth of 2016. Among the 2,534 subjects, 904 unmarried workers in their 20s and 30s were included in the analysis. Dependent variables were marriage needs, and independent variables were age, sex, height, weight, education level, monthly income, parents' economic level, and health-related variables were self-rate health, stress, regular exercise, and life satisfaction included. Statistical analysis was performed binominal logistic regression analysis. In results, there were no factors influencing perception of marriage needs in 20s men, and Education was a predictor in 20s women. In 30s men, the more regular exercise, the less the monthly income, the more positive the perception of marriage needs was. In the 30s women, the better the self-rate health, the more positive the perception of marriage needs was. These findings suggest that health may affect the marriage perception of 30s unmarried workers.

The real-name safety management system is to indicate "safety" after inspection by construction personnel before workers use it for the purpose of preventing safety accidents caused by unsafe conditions in temporary facilities and temporary constructions installed at construction sites. Purpose: By implementing the real-name system for safety management at construction sites, the objective is to respond to the "Severe Accident Punishment Act" and to improve the level of safety management at the same time. Method: In this study, a hierarchical analysis model was produced through previous studies of actual conditions such as types of safety incidents and causality at construction sites. The AHP model was used to calculate integrated weights and rankings with a pairwise comparison questionnaire for experts. Conclusion: As a result of the analysis of the upper classes, construction machinery was evaluated the highest, and real-name management system was evaluated the lowest. As a result of the lower-level analysis, it was considered that opening doors for safety facility management, tower cranes for construction equipment, management under the "Occupational Safety and Health Act" under the real-name management system, and CEO duties for safety management organizations were the most important.

This study was designed to suggest a learning organization in a medical center by examining the factors to influence effectiveness of the learning organization. We collected the data of 586 persons who participated once or more times in the learning organization managed from 2000 to 2002 by Y Medical Center located in Seoul, and included the data of 285 persons in the final analysis. The results of the study are summarized as follows. First, as the results of examining the regression coefficients to predict the effectiveness of and satisfaction with the learning organization through the learning level, learning method and learning organization constructing level as the general variables, the important influential factors were shown as follows: 1)knowledge creation, knowledge storing, private learning, organizational learning, and learning organization construction of occupational and human levels as the factors to predict the working competency; 2) learning organization construction of the human level as the factors to assume the duty satisfaction; 3) gender, working years, private learning, team learning and organizational construction level for the prediction of the organizational commitment; and 4) medical technical service, knowledge creation, organization learning, and constructing level of the environmental and human levels for the assumption of the satisfaction with experience in the learning organization. Based on the study results of the effects in managing the learning organization, we can conclude the followings. First, the members who are in various working positions and occupations need to continuously participate in the learning organization. Second, to raise the organizational outcome from the management of the learning organization, it is necessary to establish systematic concepts in the constituents of the organizational effectiveness such as working competency improvement, duty satisfaction and organizational commitment, and the experience satisfaction of the learning organization. Finally, the future of the organization depends on the learning competencies of the organization members. To continuously exist and develop the organization, the private learning of the organizational members should be constantly spread and shared over the organizational level, and the usual innovations such as repetitive and habitual organizational learning should be generally tried out throughout the whole field of the management.

This study aimed to evaluate the effects of stretching management on musculoskeletal joint pain in community indwelling elderly farmers. The study included 28 residents who lived in a rural community. All participants were assigned randomly to either the stretching group (n=13, $59.67{\pm}4.77$ year-old) or the control group (n=15, $61.44{\pm}10.41$ year-old). Respondents were interviewed by means of a structured questionnaire. Pain severity of 6 body areas caused by symptoms of work-related musculoskeletal disorders and pain severity on day time variations were measured by the visual analogue scale on a self-assessed questionnaire. The stretching group was administered stretching therapy (45 min, 2 sets, warming up and cool down, main exercise; total 19 stretching kinds of subset 5 fields) for 12 times for 4 weeks. There were no significant difference between the two groups in general social and pain characteristics. After 4 weeks of stretching, the stretching group showed significant improvements at almost all joint pain scores except arm/elbow, and day time variation scores of pain compared to both baseline scores, and with control group scores. These results showed that stretching therapy is one of the most useful modalities to manage musculoskeletal pain in community-based elderly farmers.
