Objective: This study aims to investigate subjects in recuperation to identify the following factors with regard to work-related musculoskeletal diseases: diagnosis in the context of occupational and environmental medicine; assessment systems for judging work-relatedness; recuperation management; workplace management; prevention programs; and care after returning to work. This study intends to analyze differences between subjects and determine what characteristics of subjects account for the differences. Method: A survey was administered to 1,664 workers who were approved by the Korea Worker's Compensation & Welfare Service between 2003 and 2005 for recuperation due to work-related musculoskeletal diseases. The data of 229 subjects who responded the survey questionnaire related to recuperation were analysed. Results: According to the results, demographic, occupational, and musculoskeletal disease-related factors were significant. The demographic factors included gender, age, marital status, and region, while occupational factors included working period, work type, size of workplace, and industry type. The factors related to musculoskeletal diseases were the part of the body in pain, the tissues in pain, and the existence of dysfunction. The above factors were associated with statistically significant differences in the following areas: revealed symptom period, symptoms-diagnosis period, and application for recuperation approval periods; diagnosis and care institutes for recuperarion; the state of patients (body parts in pain, tissues in pain, and existence of dysfunction); return to work; and care after returning to work. Conclusion: The results of this study can serve as basic data in setting priorities for prevention programs for work-related musculoskeletal diseases and selecting target groups.

This paper considers two-sided assembly line balancing with preemptive multiple goals. In the problem, three goals are taken into account in the following priority order : minimizing the number of mated-stations, achieving the goal level of workload smoothness, and maximizing the work relatedness. An evolutionary algorithm is used to solve the multiple goal problems. A new structure is presented in the algorithm, which is helpful to searching the solution satisfying the goals in the order of the priority. The proper evolutionary components such as encoding and decoding method, evaluation scheme, and genetic operators, which are specific to the problem being solved, are designed in order to improve the algorithm's performance. The computational results show that the proposed algorithm is premising in the solution quality.

To investigate the work-relatedness of carpal tunnel syndrome of some workers at packing department in a rayon manufacturing company, reseracher studied the symptoms and physical sign related to carpal tunnel syndrome of the workers at packing, ysrning, and washing department. The results are as follows: 1. By the results of ergonomic study, the packing work had the considerable probability to develop the carpal tunnel syndrome. 2. The prevalences of symptoms, physical sign and case by definition were higher in woman workers than in man workers. 3. In female workers, the age-agjusted prevalence rates of symptoms were 11.6/1, 000 in workers at washing department, 111.6/1, 000 in workers at packing department, and 70.1/1, 000 in workers at yarning department. In male workers, the age- adjusted rates of symptoms were 92.1/1, 000 in workers at washing department, 210.1/1, 000 in workers at packing and delivery department, and 0.0/1, 000 in workers at yarning department. 4. In female workers, the age-adjusted prevalence rates of physical signs were 119.5/1, 000 in workers at washing department, 104.4/1, 000 in workers at packing department, and 84.5 in workers at yarning department. In male workers, the age-adjusted rates of physical signs were 65.7/1, 000 in workers at washing department, 59.0/1, 000 in workers at packing and delivery department, and 176.9/1, 000 in workers at yarning department. 5. In female workers, the age- adjusted prevelence rates of carpal tunnel cases by case definition were 123.1/1, 000 in workers at washing department, 1117.2/1, 000 in workers at packing department, and 60.2/1, 000 in workers at yarning department. In male workers, the age-adjusted of cases were 355.9/1, 000 in workers at packing and delivery department, and 0.0/1, 000 in workers at other two departments. 6. The most of female workdrs at washing departmentn had the work history at packing department. 7. We concluded the carpal tunnel syndrome of female workers at packing department were work related.

This paper presents a novel diagnostic method to determine Sasang Consitution (SC) by elasticity coefficient of hand dorsal skin of elderly people. For this purpose, we carried out a clinical test, in which Our SC diagnostic tool and one Oriental medical doctor with SC medicine expertise participated to categorize 458 healthy subjects into four constitutions. After excluding heavy-noise, we extracted 295 subjects' elasticity coefficient feature data and statistically analyzed their SC relevance with ANOVA test. It resulted in that, Taeum-in has high elasticity coefficient compared to Soeum-in in a significance level of 0.05. There are no differences of elasticity coefficient in genders. This result is supported by the theory of Longevity and Life Preservation in Eastern Medicine(Donguisusebowon, 동의수세보원) which suggested that Taeum-in's flesh is solid and Soeum-in's one is tender. This is the first work which reports the relatedness of skin elasticity coefficient and SC by an objective clinical test.

According to the statistic of industrial disaster in 2006 presented by the Ministry of Labor, there were 10,235 people with occupational diseases adding 2,740 more people (36.6%) compared to the previous year. Concerning the occupational diseases, 1,607 people had brain-cardiovascular diseases comprising more than 15% of all occupational diseases, and excessive workload and occupational stress seemed to play important parts. According to Korean Society of Occupational Stress, among 7,000 workers at 254 businesses in Korea, 73% of them were reported to be exposed to potential occupational stress and 22% of them were reported to be under severe stress. The increase of occupational stress among workers comes from excessive competition caused by business restructuring, promotion competition, annual salary system and so forth. Occupational stress threatens the heath and even the life of workers and lowers business competitiveness. Using the Korean occupational stress reduction model to the workers at small and medium businesses in Incheon area, therefore, the project intends to measure the level of stress among office workers and examine its relatedness to the VTD subjective symptoms. In addition, the project intends to present some methods to reduce occupational stress and increase business efficiency at work by studying and analyzing the various elements that workers use to reduce their occupational stress.

Over decades of work, the probiotic research has grown rapidly with a number of new cultures, which is claimed a variety of benefit. However, many of the specific effects attributed to the ingestion of probiotics remain convoluted and scientifically unsubstantiated. Accordingly, the scientific community faces a greater challenge and must objectively seek cause and effect relationships for many potential and currently investigated probiotic species. Rational selection and design of probiotics remains an important challenge and will require a solid information about the physiology and genetics of candidate strains relevant to their intestinal roles, functional activities, and interaction of with other resident micro flora. As far as beneficial culture of lactic acid bacteria (LAB) is concerned, simple, cost-effective, and exact identification of candidate strains is of foremost importance among others. Until recently, the relatedness of bacterial isolates has been determined sorely by testing for one or several phenotyphic markers, using methods such as serotyping, phage-typing, biotyping, and so forth. However, there are problems in the use of many of these phenotype-based methods. In contrast, some of newer molecular typing methods involving the analysis of DNA offer many advantages over traditional techniques. These DNA-based methods have the greater discriminatory power than that of phenotypic procedures. This review focuses on the importance and the basis of molecular typing methods along with some considerations on de-sign and selection of probiotic culture for human consumption.

Human Being is being that have the reason as well as body, and first liaison consists through this body justly with outside. The essence of environmental problem such as today can speak that is a harmful traces for health that leave in air, water, soil that pass body. Actual nature is 'Ecological nature', that is necessary for human life directly in survival and offer the integrated relations with harmony. This grafting of principle, that is a construction for architecture and interior architecture in environment furtherance, is required. This is not a subject of usefulness and contemplation, but essential approach the cogredience, that is forming connection directly with nature, is required. Therefore, this research does Questel about 'Nature epistemology, which nature and human's relation can be integrated by alive practical relation. Through this, the Relatedness of 'Natural environment and construction surrounding' is accomplished 'the whole unity' and this research wish to investigate basis that a actual human work's environment can be completed as 'Ecological nature'.

This study is about family discourses of social workers in Korea. The purpose of this study is to gain suggestions of relatedness between discourse and practice by grasping the contents and meaning of discourses in social workers. 10 social workers in various fields were interviewed for this study. The results are followed: First, social workers understand family as a private space which have a meaning of shelter and refuge. Second, there are gaps between consciousness and practice of division of gender role in family. But social workers generally are inclined toward receiving division of gender role in family and applied to their family practice. Third, monolithic family image have a tendency of versatility in family structure, is inclined toward the division of gender role and myth of motherhood. Fourth, social workers perceived emotional tie as important nature of family solidarity and family as natural institution. Also these discourses of social workers were applied to their family practice. The results of this study reveals possibility that social work practice can be discoursive practice or interpretive practice.
