In order to evaluate the effectiveness of environmental intervention of work place, metal mercury concentration in air and in urine of the total 43 workers for 3years from December 1991 to October 1993 in a fluorescent lamp manufacturing industry exposed to mercury, was measured before and after implementation of controls such as establishing exhaust ventilation at the department of exhaustion, coating the floor of work place with epostane, cleaning of the floor, improved housekeeping, and etc. The results were as follows. 1. Before the intervention(December 1991) 39.0% exceeded metal mercury Threshold Limit Value(TLV, $0.05mg/m^3$). After the intervention(October 1993) 10.0% exceeded TLV and geometric mean of mercury in air was $0.1mg/m^3$, and showed effectiveness rate of intervention to be 74.4% 2. After the intervention, geometric means of mercury concentrations in air were 0.013, $0.019mg/m^3$ and showed effectiveness rate of intervention to be 76.6%, 65.5% in A factory(right tube lamp)and at exhaustion department, respectively, A follow up survey fround statistically significant reductions in mercury concetration in air three years later. 3. Mercury concentration in urine of 11 workers(29.7%) exceeded warning level of $100{\mu}l/l$ before the intervention. After the intervention, of 3workers(8.8%) exceeded warning level and geometric mean of mercury concentration($26.5{\mu}l/l$) in urine was 2.4 times than that of before the intervention. Geometric means of mercury concentrations in urine of workers at exhaustion department, at sealing and aging department were 44.0, $77.7{\mu}l/l$, respectively and they decreased 2.3, 3.2 times than that of before the intervention.

Purpose: The purpose of this study was to examine effects of music intervention on environmental stress and sleep quality in liver transplant patients who are receiving care in one-person isolation rooms of an ICU. Methods: The study was a quasi-experimental design pre-and-post nonequivalent control group. Participants were 37 patients (18 in the experimental group and 19 in the control group) who, after receiving liver transplant, were hospitalized in one-person isolation rooms of the ICU. The study covered patients admitted between August 2016 and December 2017. Earplugs and sleep shades were provided as ordinary care to both experimental and control groups, and music intervention was provided to the experimental group three times a day for 30 minutes each from the first day of hospitalization. Results: The first hypothesis, "The experimental group who received music intervention will experience a lower environmental stress level than the control group" was supported (Z=-3.212, p<.001). The second hypothesis, "The experimental group who received music intervention will experience a higher sleep quality than the control group" was also supported (t=3.715, p=.001). Conclusion: Findings show that music intervention is an effective nursing intervention to reduce environmental stress and improve sleep quality in liver transplant patients in the ICU.

This study explored the environmental health behavior intervention study for pregnant women using a scoping review. The evidence synthesis of intervention methods, research topics, outcome variables, and effectiveness was performed. Eight studies were extracted from the databases of PubMed, Cochrane Library, and RISS. The topics were nutritional interventions and behavioral interventions that can reduce exposure to fine dust, heavy metals, chemicals, and electromagnetic waves to pregnant women. The interventions were conducted through lectures, cartoons, workshops, interviews, messages, and home visits. The effect of the intervention was found to improve the health behaviors of pregnant women and to solve problems in the residential environment. Therefore, the environmental health behavior interventions for pregnant women were effective.

Purpose: The purpose of this study was to explore the effect of an environmental intervention on sleep, reported emotions and job satisfaction of rotating shift nurses in intensive care unit. Methods: The study was a non-equivalent design with a comparison group. The participants in the study were 34 shift workers randomly assigned to one of two groups. The intervention for one group was the use of an eye shield for two weeks with the other group not receiving the treatment. Data on quality of sleep, stress, depression and job satisfaction were collected from both groups at the beginning and the end of the two week period. See note at bottom page. Data were analyzed by ANCOVA using the SPSS/WIN 18.0. Results: Quality of sleep and job satisfaction were more positively reported along with reports of less depression and stress by those nurses receiving the eyeshild intervention. Conclusion: These results suggest that the eyeshield intervention may be an effective intervention.

The reference study was performed to investigate the nursing importance which was based a theoretical background related to horticultural therapy and to examine the possibility which horticultural therapy was applicable as a nursing intervention through analysis on a preceding study. The research subjects related to the areas of horticultural therapy which related as a nursing intervention, were psychological, physical, environmental, and psycho-social aspects. It is judged that the horticultural therapy is effective in treating depression, emotional disruption or anxiety. It seems to be also effective in increasing the muscular tension and, thereby, expanding the scope of joint movements. Such theories show that horticultural therapy may be a good alternative nursing means. Plants act to create a pleasant interior atmosphere by generating anion, controlling the temperature and humidity and purifying the air, and therefore, the horticultural therapy may be applied to clinic or environmental therapy. When horticultural therapy is used as a nursing intervention, patients' sociopsychological needs may be fulfilled. It has been found that horticultural therapy is instrumental in treating perceptive or emotional disruption, depression, loss of self-respect, disrupted everyday activities and social behaviors. In particular, horticultural therapy seems to be effective in managing chronic patients' crisis or improving life quality. Intervention method applied on a preceding study was activity therapy and scene therapy in the horticultural therapy The above findings suggest that the pro-environmental horticultural therapy is useful as a new paradigm of nursing or holistic nursing conducive to improvement of health. So, it is desirable to prove its effects by applying it in the clinic. In order to apply horticultural therapy as a nursing intervention, it will be necessary to educate nurses on principles and methods of horticultural therapy and encourage them to apply it in nursing and clinics. Moreover, it may well be necessary to develop landscape therapy as nursing intervention as well as a variety of horticultural therapy programs befitting the clinic conditions. On the other hand, we need to provide for some scientific ground for horticultural therapy through continued studies. In this regard, this study which focuses on patients' health improvement through change of environment. may well provide for a framework for such studies.

Objectives Bedding in childcare centers (CCCs) can hold house dust mite (HDM) allergens. This study examined whether HDM allergen levels can be reduced through the distribution of an educational newsletter on bedding control to parents of CCC children in Korea. Methods All 38 CCCs were measured for Der 1 (sum of Der f 1 and Der p 1) concentrations on classroom floors and bedding before the intervention. Educational newsletters on children's bedding control were sent to 21 CCCs by mail, and teachers were asked to distribute the newsletters to the parents of the children (intervention group). The remaining 17 CCCs were not sent newsletters (control group). The measurement of Der 1 concentrations in 38 CCCs was repeated after the intervention. Dust samples were collected with a vacuum cleaner and analyzed using enzyme-linked immunosorbent assay methods. Results The Der 1 concentrations on the bedding were significantly higher than those on the floors in 38 CCCs at baseline (p < 0.05). Although changes of the Der 1 concentrations for the control group (n=17) were not significant, Der 1 concentrations for the intervention group (n=21) decreased significantly from 2077.9 ng/g dust to 963.5 ng/g dust on the floors and from 3683.9 ng/g dust to 610.4 ng/g dust on bedding (p < 0.05). Conclusions The distribution of educational newsletters on bedding control to parents may be an effective means of controlling HDMs in CCCs.

This study estimated the urbanization effect of Seoul, the largest city in Korea, on its rainfall. For a comparative analysis, two different data sets are used: One is the precipitation data at the Jeonju rain gauge station, which has a relatively long record length but least urbanization effect, and the other at the Ichon rain gauge station, which has a short record length but located very near to Seoul with least urbanization effect. Also, the difference of the rainfall between Seoul and Jeonju rain gauge stations, as an indicator of urbanization effect, is quantified by use of the intervention model. As a result, it was found that the maximum rainfall intensity of the annual maximum rainfall events shows the increasing trend, its duration the decreasing trend, and the mean intensity the decreasing trend especially after 1960. Also, the quantification of urbanization effect using the intervention model shows that the increasing trend of rainfall intensity and total volume is still on going.

Purpose: This study was to identify the effects of hope intervention on hope and depression of cancer patients staying at home. Methods: The study design was a randomized control group design. The subjects consisted of forty cancer patients randomly selected who were registered at S-Gu Public Health Center. Hope intervention, which was composed of hope assessment, hope objective setting, positive self identity formation, therapeutic relationships, spiritual & transcendental process improvement, positive environmental formation and hope evaluation, was provided from November 20, 2006 to January 26, 2007. Results: The 1-1 hypothesis, "The experimental group which received hope intervention will have a higher score of hope than the control group", was supported(t=-3.253, p= .003). The 1-2 hypothesis, "The experimental group which received hope intervention will have a higher level of hope index than the control group", was supported (t=-4.001, p= .000). Therefore the 1st hypothesis, "The experimental group which received hope intervention will have a higher level of hope than the control group" was supported. The 2nd hypothesis, "The experimental group which received hope intervention will have a lower level of depression than the control group", was not supported (t=1.872, p= .070). Conclusion: Hope intervention is an effective nursing intervention to enhance hope for patient with cancer.
