The objective of this study were to identify the state of re. cognition and attitude of residents in Seoul city about air environment and to identify factors affecting attitude toward air environment. Study object was residents in Seoul city sampled by multistage random proportional sampling. Sample size was 0.0067%(500 persons) of total residents in Seoul city. The results were divided into two parts: (1) descriptive results of recognition and attitude toward air environment, (2) results of factor analysis to classify categories of attitudes toward air environment and regression analysis to identify factors affecting attitude toward air environment. Most of resident in Seoul city recognized that air environment in Seoul city was highly polluted and was not satisfactory. Experience of damage of air pollution was reported in about 70% of residents in Seoul city. More than 60% of residents in Seoul city had concern about air environment. Attitude toward air environment were classified into four categories using factor analysis: Necessity of intervention of local government for air environment conservation, Participation of residents and enterprises for air environment conservation, Optimistic attitude about air pollution, Preference of economy. Factors affecting the above attitudes were knowledge about air pollution, knowledge about policies and institutions related air environment conservation, concern about air environment, educational level, subjective assessment of air environment, sex, marital status. In conclusion this study suggested providing information of air environment in Seoul city to the residents and to educating residents for making positive attitude about air environment conservation.

Purpose: Cancer-related fatigue is frequently experienced by patients during and after therapy. The present study was conducted to assess the impact of energy conservation strategies and health promotion in breast cancer survivors. Methods: A randomized controlled trial was carried out to compare the intervention effect (n=69.0) with controls (n=66.0) based on routine oncology ward care. The intervention was five weekly sessions for groups of 6-8 breast cancer survivors. Data on fatigue and health promotion lifestyle were obtained before and after completion the intervention and then 8 weeks later for analysis of variance (ANOVA) with repeated measures. Results: Our findings showed cancer-related fatigue to be reduced in the intervention group from pre- to post-intervention, and this persisted over the 8-weeks follow-up period (F = 69.8, p<0.001). All subscales of the cancer fatigue scale demonstrated statistically significant effects with partial eta-squared values ranging from 0.15 (the smallest effect in cognitive fatigue) to 0.21 (the largest for affective fatigue). Changes in the health promotion life style indicated a significant promotion from pre- to post-intervention, and this again continued after 8-weeks follow-up (F = 41.6, p < 0.001). All six domains of a health promoting life style featured significantly elevated values, the largest effect being seen in the interpersonal relations subscale (F=57.7, partial ${\eta}^2=0.21$, p<0.001) followed by physical activity (F=51.9, partial ${\eta}^2=0.18$, p<0.001). Conclusions: The program was effective in decreasing cancer related fatigue and promoting a healthy lifestyle.

Objectives: This study aimed to investigate stages of safety and health culture change through a reflection on 40 years of hearing conservation history at a multinational company. Methods: The target workplaces were multinational companies with more than 1,000 employees. The research used the clinical case study and system analysis methods based on direct observation of the research from 1994 to 2009. The latter method performed an analysis of the equilibrium state of the cross-section in the given period and the longitudinal profile of the change during the given period. Results: The stages of cultural change are divided into five stages and summarized as follows. In the first stage, workplace noise was not widely recognized as a hazard, while in the second stage, the measurement of noise levels and audiometric testing were conducted under the Korean Occupational Safety and Health Act (KOSHA). The driving force for change in the second stage was the amendment of the KOSHA. In the third stage, noise came to be recognized as a hazard factor through awareness training. The driving force of change during the third stage was the strong executive power exerted by the audit of the industrial hygiene program from the US head office. In the fourth step, there was a change to actually reduce noise. The driving force in this stage was a change in company executives' risk perception resulting from lawsuits over noise-induced hearing loss and the task force team activities for culture change based on the action learning protocol. At the fifth stage, a 'buy quiet policy' was institutionalized. The management's experience that noise reduction was difficult was the motivation to manage noise from the time of purchase of equipment. Conclusions: The activities of a hearing conservation program are determined by the improvement of the legal system and by the way it is enforced. Noise control activities to reduce noise areas may be possible through the shared risk perception of noise-induced hearing loss and by a change agent role as a facilitator to implement noise control.

It is a global consent that we should conserve our energy consumption, due to our awareness to the environmental problems and the limitedness of the natural resource. In the country, the level of energy consumption is more than it is needed, according to its living standard and the proportion of resources imported from other countries. Educational program focused on energy conservation is essential to overcome these problems. This paper outlines a basic study on the development of an energy conservation education program for children. This program makes students aware of the importance and difficulties in energy conservation. The students can then make their own contribution and besides circulation of resources and improvement of health problems.

Purpose: The purpose of this study was to investigate the effects of peer mentoring program on physical activity, knee joint function, self-care agency and social support, which are health conservation elements in elderly women with osteoarthritis. Methods: This study used a quasi-experimental research design. It is a pretest-and-post 1, post 2 test design of a non-equivalent control group. The subjects were elderly women aged over 65 who were diagnosed with osteoarthritis. A total of 60 patients (experimental group 30, control group 30) who registered with the Senior Welfare Center in City G and in Region D participated in this study. The data were collected from June 29th to September 4th, 2015. The collected data were analyzed with $x^2$ test, Fisher's exact test, independent t-test and repeated measurement ANOVA. Results: The experimental group showed a greater increase in physical activity, knee joint function, self-care agency and social support than the control group. Conclusion: The results indicated that the peer mentoring program is effective in increasing physical activity, knee joint function, self-care agency and social support of elderly women with osteoarthritis.

This study was conducted to develop and apply the health conversation program to determine its effectiveness. The study employed a pretest-posttest nonequivalent control group design. There were 25 subjects in one intervention group and 22 subjects in the control group. The program included a 4-week, 12-session education program in health conversation for professionally retired elderly mentors and an 8-week, 24-session program for vulnerable elderly diabetics provided by mentors who were older persons trained in diabetes management. Data were collected from December 2015 to May 2016 and subsequently analyzed by an independent t-test using SPSS 20.0. Biochemical variables and physical variables were assessed by blood test and Inbody 230 (Biospace). Psychosocial variables were assessed by questionnaires. The health conservation program led to significantly decreased FBS (p<0.01), TC (p<0.01), TG (p=0.04), SBP (p=0.03), waist (p<0.01) and symptoms of depression (p=0.01), and significantly increased social support (p=0.02). These results indicated that the health conservation program is effective at increasing social support and decreasing FBS, TC, TG, SBP, waist, and symptoms of depression in community-dwelling vulnerable diabetic elderly; accordingly, health conservation programs should be applied to improve quality of life of vulnerable diabetic elderly.

Swertia chirata is an endangered gentian species that prefers to grow at higher altitudes. This ethnomedicinal herb is known primarily for its bitter taste caused by the presence of important phytochemicals that are directly associated with human health benefits. Due to a continuous loss of habitat and inherent problems of seed viability and seed germination, alternative strategies for propagation and conservation are urgently required to prevent the possible extinction of this species. We have formulated a reproducible protocol for the rapid propagation and conservation of this plant using leaves taken from in vitro shoot cultures. Direct induction of more than seven shoot buds per explant was achieved for the first time when the explants were placed on MS medium supplemented with $2.22{\mu}M$ N-6-benzyladenine, $11.6{\mu}M$ kinetin, and $0.5{\mu}M$ ${\alpha}-naphthalene$ acetic acid. Direct organogenesis was noted exclusively from the adaxial surface of the basal segments of leaves. Leaves closer to the apical meristem were more responsive than those farther away from the meristem. Plants raised through direct organogenesis were evaluated for their clonal fidelity by chromosomal analysis and DNA fingerprinting. Complete plants were successfully transferred to the field condition and produced viable seeds. Given the enormous potential of this age-old medicinal plant in terms of potential health-benefitting drugs, this protocol can be used for commercial propagation purposes and to initiate future genetic improvement studies.

The effect of seawater and air pollutants on the three-story stone pagodas on Gameunsa Temple Site have been studied in order to establish conservation basic plan. Also, an experimental study has been conducted to evaluate the effect of seawater salt and air pollutants on the weathering of granite. The results could be summarized as follows. Because the three-story stone pagodas on Gameunsa Temple Site are located outdoors, the external appearance has been largely deteriorated due to natural and artificial factors such as typhoon, wind, microorganisms, moisture, extreme change in temperature, air pollutants, and seawater, etc. When G.J fresh granite was dipped into the seawater, dissolution rate of three minerals (Mg, Ca, and K) are increased linearly until about 40 days and then increased abruptly. After seawater dipping experiments, the mineral compositions of the granite surface were lower then that of the G.J fresh granite but Poisson's ratio and absorption ratio were slightly increased. Therefore, from these results we can say that stone cultural properties could be weathered by seawater and air pollutants and it's considered being a meaningful experiment to study the conservation method of stone cultural properties from seawater.
