Percent dormant root and percent missing root were investigated in ginseng (Panax ginseng) plantations and correlated with soil chemical characteristics. Percent dormant root showed no consistency with root age and significant positive correlation with percent missing root in many cases. Percent dormant root showed significant positive correlation with available phosphorus and phosphorus-moisture ratio in soils. Percent missing root showed significant negative correlation with moisture and calcium in soil and positive one with phosphorus - moisture ratio. Above results strongly suggest that excess phosphorus and water stress are the common causes of dormancy and missing of root.

Purpose: The purpose of this study was to examine the presenteeism and absenteeism in relation to the health problems of nurses. Method: Informed consent was provided before study. Data was collected from January 7 to March 6, 2008 by Stanford Presenteeism Scale-13. Data was collected from 3 hospitals in Seoul Gyeonggi area. The response rate of the questionnaires was 96.2%. Incomplete data was analyzed using SPSS program. Results: Shoulder, back and neck pain were the highest reported health problems and primary health Problem of nurses. Impaired presenteeism was ranked in this order: depression or anxiety, cold, and uterus or ovary disorder. Absenteeism was ranked in this order: uterus or ovary disorder, cold, and dermatological problem. Impaired presenteeism was significantly increasing according to the number of health problems. But Absenteeism was not. Presenteeism was significantly different by age, educational level, religion, whether or not the worker lived with their family, marital status, whether or not the worker has children, time spent in the workforce, experience of turnover, shift work, night work, and level of satisfaction with salary. But absenteeism was not significantly different given these criteria. Conclusions: Health problems of nurses can negatively effect the quality of nursing service and productivity at hospital. Therefore the hospital administrator should control the presenteeism and absenteeism through the management of health problems of nurses.

Objectives : The purpose of this study was to examine the relationship of stress, health problems, absenteeism, productivity and presenteeism in Korean and Japanese workers. Methods : Data was collected from April 12 to July 18, 2008 in both countries. The content of questionnaires was demographic factors, stress and the Stanford Presenteeism Scale. Korean data from 810 workers was collected and Japanese data from 822 workers was collected by same questionnaires of both language. SPSS 12.0 and AMOS 5.0 programs were used for data analysis. Results : The major health problems in relation to the impaired presenteeism of Korean workers were dizziness, allergy, headache and dysmenorrhea, and for Japanese workers were arthritis, depression, and diabetes mellitus. Impaired presenteeism was increasing when the numbers of health problems were increasing in both countries. In Korean workers, job-related stress and the numbers of health problems directly affected presenteeism. In Japanese workers, job-related stress, life-related stress and the numbers of health problems directly affected presenteeism. Conclusions : Health managers should include physical and psychological health management programs for presenteeism control in workplace. They can obtain a greater benefit through both programs.

Effects of straw mulching on growth of shoot and root of Panax ginseng, soil physical and chemical characteristics were investigated. Straw mulching increased root yield, stem length, leaf area and decreased defoliated plant rate and missing root rate. Percent solid phase and soil hardness decreased, and porosity, percent air phase and percent liquid phase increased under straw mulch. It increased soil water content and decreased soil temperature especially in the rear side of the bed. Available soil phosphorus (very harmfully in some case), exchangeable potassium, organic matter increased while exchangeable calcium decreased and the lowering of pH was retarded under mulch. Straw mulching greatly reduced need population, prevented soil covering on the lower side of leaves and eliminated solings to plants, bed sides and on bed top.
