The purpose of this study was to investigate whether nutrition counseling could lead to a beneficial outcomes in patients with cardiovascular disease(CVD). Fifty CVD patients(23 men and 27 women) participated in a dietary counseling program which was based on serum lipid management. Various markers of disease risk including lifestyles, anthropometric indices, eating behaviors, serum lipids, antioxidants, lipid peroxides were measured before and after the program. The program lasted 3-11 months depending on individuals. Waist/hip ratio decreased after nutrition counseling only in women. Smoking and alcohol drinking status did not change significantly after counseling. Food habit score increased significantly in both men and women(p<0.05), and patients consumed mixed cereal rice, fruits, seaweeds, legumes more frequently and snacks less frequently after nutrition counseling (p<0.05). Although intakes of energy, carbohydrate and vitamin B1 were reduced significantly after nutrition counseling, nutrient densities of calcium and iron of diets have increased significantly after nutrition counseling, and those of other micronutrients were not different Serum total cholesterol decreased significantly in men and LDL cholesterol decreased significantly in women. In women lipid peroxide level decreased and $\alpha$-tocopherol level increased significantly, while there was no significantly change in men. We conclude that well-planned nutrition counseling would reduce risks of cardiovascular disease through improving dietary behavior, lipid profile and antioxidant status.

This study was performed to show change of fat-free mass(FFM), representing mostly the muscle mass change, and muscle strength with increasing age, and relationship between dietary, exercise behaviors and FFM in healthy middle-and old aged women who are of age over 55 years. The FFM and correspondingly hand grip strength showed significant positive correlation with age. But concentration of serum albumin showed no significant relationship with age. The subjects were categorized into groups according to FFM tertile. The anthropometry such as weight, BMI, fat mass, circumferences of waist and hip, WHR, and hand grip strength decreased significantly in the lowest FFM group. But the albumin level showed no change according to FFM level. The FFM showed significant correlation with nutrient intakes such as energy, carbohydrate, protein, Fe, P, Ca. No association, however, was shown with exercise behavior probably because of no case with resistance exercise habits. The variance of FFM was explained 55.2% by height and carbohydrate intake. The variance of height-adjusted FFM could be explained only 16.2% by intake amount of carbohydrate. In conclusion, the decrease of FFM may cause to reduce muscle strength in female elderly. The increasing nutrient intakes were associated with the increased FFM and may protect from risk of sarcopenia. However, only the carbohydrate intake could influence independently the FFM in middle- and old-aged women. The FFM has no association with endurance exercise habits.

Good sleepers tend to more resilient than poor sleepers. As sleep and resilience may have a bidirectional relationship, it is important to explore the relationship between healthy sleep and resilience. Objectively and subjectively measured sleep quality showed positive association with resiliency. In one study, more resilient adolescents had higher sleep efficiency, less light sleep, more slow-wave sleep, and a smaller number of awakenings after sleep onset. Circadian typology, jetlag and circadian misalignment may be associated with the capacity to deal with adversity. Eveningness, exposure to chronic jetlag and circadian misalignment might be risk factors for development of psychological problems and mental disorders. Additional studies are needed to evaluate whether promoting healthy sleep behaviors results in increased resilience.

The mission of the doctors is to take care of human life, body and health through the medical behaviors such as diagnosis and treatment. Under this job propensity, the doctors have care duty to take the best actions required to prevent the risk according to the patients' specific disease status. Such care duty of the doctor may be evaluated based on the medical behavior level at the medical institution and clinical medical study field. Such medical level should be understood in the normative level, considering the treatment environment, condition and specialty of the behavior, because it means the medical common sense known and acknowledged to the normal doctors. While the criminal suit requires the evidence for no doubt conviction, the civil suit requires more eased different standard. The results between the criminal and civil sentence may be different, because the confirmed former case may lead to long-term imprisonment and even death penalty, while the latter case puts only monetary penalty on the defeated party.

Emission of hazardous and volatile organic chemicals from solid waste landfill site was become to important issue because of environmental pollution and health risk by such chemicals. Laboratory batch and continuous experiments were conducted respectively to elucidate isothermal sorption behaviors and transport phenomena(by gas through unsaturated solid waste layer) in wet solid waste-gas system. Source separated and size reduced refuse(bulky waste) and incinerated ash were used after controlling water content, and trichloroethylene(TCE) was chosen among many such chemicals because of it's generality among those man-created pollutants. Isothermal TCE sorption equilibria wet solid waste-gas system can be described in linear equation and partition coefficient in this system can be estimated approximately by the simple equation derived from schematic structure of the system. Transport equation modified by instantaneous equilibrium sorption fraction and kinetic sorption rate(overall mass transfer capacity coefficient) simulated well the column experiment results.

Purpose: This study was conducted to develop an instrument measuring awareness of osteoporosis. Methods: The process included construction of a conceptual framework, generation of 86 preliminary items, verification of content validity, selection of secondary items, verification of construct validity and extraction of final items. The 86 items were reviewed for content validity by two groups of experts and were tested to evaluate inter item correlation coefficient by two groups of adult women. From June to August 2007, data were collected from 383 adult women who lived in Seoul and provinces in Korea. Data were analyzed by performing item analysis, Varimax factor analysis and Cronbach's alpha. Results: There were 31 items in the final instrument categorized into 5 factors. The factors were labeled as "preventive behaviors (10 items)", "risk factors (5 items)", "characteristics of osteoporosis (6 items)", "improving bone health (5 items)", and "bone physiology (5 items)". Cumulative percent of variance was 60.92% and eigen values ranged from 1.20 to 12.44. Cronbach's alpha was .948 and ranged from .804 to .917. Conclusion: Validity and reliability of the scale are confirmed in this study showing its utility for measuring awareness of osteoporosis for women. Utilization of the scale will also contribute to designing an appropriate prevention program for osteoporosis.
