This study was carried out to examine information regarding usage of health improving agents and health status of male workers in the Chonnam Yeosu industrial area. We obtained data by means of a questionnaire from 329 men. Of the subjects 44.7% were in their forties, high school education was 43.0%, married was 83.0% and $1,500{\sim}3,000$ thousand won in monthly income was 35.8%. Average height and weight of the subjects was $171.8{\pm}5.4 cm$ and $70.5{\pm}8.1 kg$. Average BMI was $23.8{\pm}2.2$. Drinking rate of respondents was 85.5%, the drinking rate of daily workers was significantly higher than rotation workers (p < 0.05). Rotation workers exercised more regularly than daily workers (p < 0.001). Subjective symptoms of the subjects always had eye problems (11.7%), shoulder aches (5.8%), ache in one's empty stomach (4.7%) in decreasing order. 21.4% of the subjects had a disease, and liver disease was the highest in the subjects; the second was cardio-vascular disease. Interval of health food intake was highly irregular (62.7% of respondents), and keeping healthy was the main motivation fur the usage of health foods. Health improving agents included oriental medicine, animal protein based restorative foods, nutrition supplements, health supplements, and natural foods. 33.3% of the subjects took health supplements, nutrition supplements (29.1%), oriental medicine (20.6%), natural foods (16.7%) and animal protein based restorative foods (3.9%), in respective order. Health improving agents were consumed higher in liver disease than other diseases. This study suggests that nutritional education and monitoring should be implemented for industrial workers to prevent life-habit diseases and to keep proper self-management of health status under special environments.

This study explores some basic issues behind adults' seeking and using patterns of alternative medicine as well as health food (health food/medicine). In order to do this, 791 adult participants in Seoul and Busan were interviewed face-to-face. The results of the survey showed that 1) interpersonal influence was the most influential factor in relation to the adoption of health food/medicine(46.9% of the participants reported on the influences), 2) keeping healthy was the main motivation for the usage of health food/medicine(34.5% of the participants), 3) mass media was the important information source for health food/medicine, 4) with regard to trustworthiness of information sources, experts were believed to be the most trustworthy while information from acquaintances were thought less, and finally, 5) pharmacies and health food stores were main suppliers of health food/medicine. This study suggests some marketing strategies for health food/medicine. For example, it can be suggested that interpersonal communication among other information channels should be focused and might be increased trust by using professionals.

Korean people use a lot of herbal agents for medical purposes, such as curing diseases, improving health state, but some of the herbal agents have toxic side effects. In terms of toxicology, herbal agents classified into 3 categories generally nontoxic, potentially toxic and toxic. But, there are few studies about the mechanisms and clinical features of intoxication of herbal agents. So detoxification or initial treatment of these agents is very difficult to clinicians in hospital. Authors experienced an uncommon case of intoxication after Arisaematis Rhizoma Ingestion. We report this case with review of Arisaematis Rhizoma.

This study was performed to find out factors affecting degree of satisfaction with workers' working environment. The study subjects were 165 workers who were working at painting process of twelve furniture manufacturing factories in Incheon area. We used self-administered questionnaire containing general characteristics, working conditions, the degree of satisfaction with working environment, and the degree of satisfaction with working condition. In addition, we measured the exposure levels of occupational hazardous agents. The results were as follows; 1. Correlations between the degree of satisfaction with workers' working environment and the measured of occupational hazardous agents did not affect the degree of satisfaction with workers' working environment. 2. Factors affecting the degree of satisfaction with workers' working environment were not the exposure levels of occupational hazardous agents, but the degree of satisfaction with working condition, size of industry, health status, and types of ventilation system. As the degree of satisfaction with working condition was increased, the degree of satisfaction with working environment was increased. Also, for the workers who had good health status, the degree of satisfaction with work environment was appeared to be high. To increase the degree of satisfaction, with workers' working environment, firstly, effective work management and production control are required. Also, the worker's effort to negotiate continuously with top manager on improving working conditions is required. Secondly, developing heath promotion program to be appropriate for the characteristics of worksite is required. Moreover, leading worker's participation in health promotion program is very important to increase the degree of satisfaction with workers' working environment.

Bacterial resistance to commonly used antibiotics is one of the major challenges to be solved today. Bacteriophage endolysins (Lysins) have become a hot research topic as a new class of antibacterial agents. They have promising applications in bacterial infection prevention and control in multiple fields, such as livestock and poultry farming, food safety, clinical medicine and pathogen detection. However, many phage endolysins display low bactericidal activities, short half-life and narrow lytic spectrums. Therefore, some methods have been used to improve the enzyme properties (bactericidal activity, lysis spectrum, stability and targeting the substrate, etc) of bacteriophage endolysins, including deletion or addition of domains, DNA mutagenesis, chimerization of domains, fusion to the membrane-penetrating peptides, fusion with domains targeting outer membrane transport systems, encapsulation, the usage of outer membrane permeabilizers. In this review, research progress on the strategies for improving their enzyme properties are systematically presented, with a view to provide references for the development of lysins with excellent performances.

A new herbal composition. HemoHIM, was developed using irradiated animal models and was successfully applied as an immune-improving agent. In a view that the protection and recovery of immune, hematopoietic and self-renewal tissues are essential for radioprotective agents, HemoHIM was developed based on a novel combination of three edible herbs (Angelica Radix, Cnidii Rhizoma. Paeonin Radix) that meet all those requirements. HemoHIM significantly protected the immune and hematopoietic system and enhanced their recovery in y-irradiated mice. For the application of HemoHIM as a health functional food and a supplementary agent for the cancer patients, the efficacy of HemoHIM to improve the immune functions was further evaluated in immune-depressed animals and humans. Animal studies demonstrated that HemoHIM significantly improved the immune functions in cyclophosphamide-treated mice, aged mice, and dexamethasone-treated mice. In human studies, HemoHIM enhanced the immune activity and cytokine secretion in sub-healthy volunteers, and alleviated the severe leukocyre depression in cancer patients during radiation and chemotherapy. Based on these results, HemoHIM was approved by Korea FDA as a material of health functional food for immune function improvement and will be commercially available soon. This case of HemoHIM research and development suggested that irradiated animals can be good models for biological degenerations such as immune depression, self-renewal tissue damage, and aging for the development of biological modulators.

The unnatural dead body refers to a corpse which is suspicious of unusual death and the dead case has been occurred more than 20 thousands times every year during the recent five years and most of them are found decayed. Police Scientific Investigators investigate unnatural dead bodies and its surroundings in all-around way and determine whether the death is involved with a crime, and most of the Scientific Investigators are exposed to a danger to get infected with pathogenic bacteria which are generated during the decaying process of dead body and are mostly to cause serious injuries on human beings. In line with the fact, the present study conducted a bacterial analysis by collecting excretions from 60 dead bodies and culturing the bacteria to evaluate infection risk of the police agents. The study cultured bacteria from 60 bodies and classified pathogenic bacteria of 108 strains, and its main bacteria are found to be them (; Acinetobacter baumannii 20 strains (19%), Pseudomonas aeruginosa 19 strains (18%), E. coli 18 strains (17%), Klebsiella pneumoniae 11 strains (10%), Proteus mirabillis 10 strains (9%), Enterococcus faecium 10 strains (9%), Staphylococcus aureus 9 strains (8%), Bacillus spp. 5 strains (5%), Streptococcus pneumoniae 3 strains (3%), Candida albicans 2 strains (2%), Mycobacterium tuberculosis 1 strains (1%)). The study results are expected to be used as educational data for preventing the Police Scientific Investigator from infections with bacteria or as a minimum data for improving work environment of the agents.

Probiotics may be defined as microbial agents that can benefit humans and have been used primarily by mankind in fermented foods. A representative of probiotics is lactic acid bacteria (LAB), which has received attention recently due to its perceived health benefits. We reviewed research papers about Bifidobacerium and Lactobacillus, which are two of the most known of the LAB. Bifidobacerium alleviates diarrhea from various causes by improving intestinal microflora, and it has been reported that it reduces Helicobacter pylori bacteria known as the cause of gastric ulcer and stomach cancer. Bifidobacerium has also reported to be effective on immunization and allergy, reduce blood cholesterol, cancer, lactose intolerance. Lactobacillus alleviates diarrhea but has not fully demonstrated its effectiveness relative to other health issues. Several lactic acid bacteria and yeast are expected to act as probiotics, so, in the future, more research on the health benefits of lactic acid bacteria is needed.
