A companion animal is a pet which lives and shares emotions with a person. The global pet industry economy has grown in recent times due to increased awareness of companion animals. In Korea, it grew from 800 million US dollars in 2012 to 2 billion US dollars in 2016, about 2.5-fold growth in five years. Within the pet industry, the pet food market occupies the largest market share having a value greater than 70 billion US ollars globally. In China, the average annual growth rate of the pet food industry is estimated at about 30%, and the market size is expected to reach 18 billion US dollars by 2020. The companion food market has potential to be the fastest growing and most viable food market in the future and would be a strategic employment avenue within the food industry. This report articulates the necessity for product development and institutional improvement of companion animal.

This study was conducted to examine the effect of chronic low dose organic solvent exposures in the industries towards then neurobehavioral functions of workers. Subjective symptoms on neurobehavioral function as well as a visual reaction time test (Flicker test) were administered to 94 exposed and 162 unexposed workers in a oil refinery and some other auto-repair shops. The results obtained were as follows : 1. Symptom complaints were higher and Flicker test values were lower in exposed workers than in unexposed workers. 2. Flicker valus were Inversely correlated with urinary Hippuric acid concentration in exposed workers(r=-0.26, p<0.05). 3. Flicker valus were inversely co..elated with Subjective symptom score(r=-0.15, p<0.05). Low Flicker value were also related with some subjetive symptoms such as 'Dimmed vision', 'Nightmare', 'Weakness on extrimity' in workers as a whole. While symptoms of 'Dimmed vision ', 'Nightmare' only observed among exposed workers.

Objectives: Stress hormone (cortisol) can be used to analyze psychological and physiological changes and healing effects before and after in blood and saliva. Here it is applied to scientifically validate the effects of the healthy forest experience in Deogyusan Mountain National Park. Methods: A healthy forest experience program was provided to college students (males and females) at Deogyusan National Park. Stress, hormones (cortisol), blood pressure, pulse, oxygen saturation and stress, anxiety, and depression were measured. This study was designed to objectively analyze the effects of stress hormones before and after. Results: Depression, stress, anxiety, and satisfaction with the forest experience program in Deogyusan National Park were very high in reliability in terms of Cronbach’s Alpha: depression scored 0.910, stress 0.558, anxiety 0.934, program satisfaction 0.826, and program effectiveness 0.894. Conclusions: In this study, we utilized the Healthy Forest Experience Program and the ‘Health and Medical Center Health Record Book’ of the Health Forest Experience Program (Ministry of Environment’s Environmental Education Certification Program). In the future, we will seek ways to utilize saliva since it is easier to collect than blood samples and apply the stress hormone cortisol as a saliva authentication program. In addition, by implementing ecological welfare programs in which nature and human beings coexist through systematic preservation and restoration, the national park management can utilize ecological, scenic and cultural services wisely. We expect to be able to provide exploration and welfare services.

The genetically determined ability to metabolize debrisoquine (DBR) is related to risk of lung cancer and DBR hydroxylation exhibits wide inter-individual variation. In this study, 100 korean adults were tested for their ability to metabolize DBR. The DBR metabolic phenotype were determined by metabolic ratio (MR, DBR / 4-HDBR) which is the percent dose excreted as unchanged DBR divided by the percent dose excreted as 4-hydroxyebrisoquine(4-HDBR) in a aliquot of an eight hour urine sample, after 10mg DBR test dose administration. Analysis was performed on a capillary gas chromatograph fitted with electron capture detector. The results were as follows; 1 Geometric mean of DBR MR was 0.32 in male,0.27 in female,0.30 in total and the distribution of log (MR) was seemed to follow normal distribution. 2. Metabolic ratio of DBR was higher in non-smoker and non-drinker than in smoker and drinker without any statistically significant difference. 3. None of personal factors was significantly related to DBR MR except age. 4. The DBR metabolic phenotype was extensive metabolizer(EM) 93, intermediate metabolizer(IM) 7 by traditional method and EM 98, IM 3 by Caporaso's method. The poor metabolizer (PM) phenotype was not found by either method. 5. Maximal expected PM phenotype was 0.36% by traditional method and 0.04% by Caporaso's method.

To assess the adverse effects of dust on pulmonary function and to determine the association between subjective respiratory symptoms, cognitions about working environments and pulmonary functions, the study was conducted on 719 coal mine workers(395workers on direct part, 324 workers on indirect part) being employed in a coal mine industry located in Hwa-Soon area. Questionnaires on respiratory symptoms and cognitions about working environments were filled out by themselves, and pulmonary function test was given by trained doctors. The results obtained were as follows; 1. significantly increased subjective respiratory symptoms prevalence were found in the workers on direct part comparing to workers on indirect part, and symptoms prevalence rate was higher in sputum, coughing, respiratory difficulty, palpitation and chest pain in order. 2. Significantly increased cognitions degree about working environments were found in workers on direct part comparing to workers on indirect part, and the degree was higher in dust concentration, temperature, working density and humidity in order. 3. FVC, FEV0.5, FEF200-1200ml and FEF25-75% were lower for workers on direct part than that for workers on indirect part. 4. In workers on direct and indirect part, lung functions FEF200-1200ml for the high subjective symptom group was smaller than that for the low group. There was not significance statistically, but the significance was found in FVC and FEVt in total coal workers. 5. In workers on direct part, FEVt and FEF25-75% for high cognition group about working environmental conditions was smaller than that for the low group but other lung functions were reversed. But in workers on indirect part, similiar result was found and the significance was found in FEV0.5 FEF25-75% and FEF200-1200ml in total coal workers. 6. Lung functions had negative correlation with subjective symptoms and cognition about working environment except correlation between sputum and FEF200-1200ml.
