The adolescent birth rate has doubled in the recent decade. As a result, the Korean government has implemented support for adolescent single-parent families by expanding the scope of coverage of the Single-parent Family Support Act in 2010. In order to understand whether experiences of facility entry programs and the Single-parent Family Support Act for adolescent single-parents were helpful or not, this study verified the relationship to mental health. This study utilized a part of the National Youth Policy Institute's 'Research on the Actual Condition of the Adolescent Pregnancy, Birth and Rearing Children.' Participants of the study were 218 adolescent single-parents at the age of 24 and younger. This study used the research methods of descriptive statistical analysis, ${\chi}^2$test, t-test, and one-way analysis of variance. The findings and discussion of this study are as below: Firstly, the depression level of adolescent single-parents who had been raised by grandparents was higher than other family types to a meaningful standard and adolescent single-parent's cognition of the original family's economic level was related to self-esteem and parenting efficacy. Secondly, the practical single-parent family support policy for adolescent single-parent's pregnancy, birth and rearing children has shown a higher reception rate, and medical service of facility entry programs has a higher satisfaction level. However, some of the facility entry programs and the Single-parent Family Support Act have a low reception rate and it should be considered whether to maintain them or not.Lastly, parts of facility entry programs and the Single-parent Family Support Act for adolescent single-parents have increased self-esteem and parenting efficacy and reduced parenting stress and depression's levels.

Objective: This study aims to analyze the characteristics of occupational accidents and injuries of telecommunications line and cable workers by type of workplace and operational process of cabling service and to provide baseline data in establishing the preventive policies for occupational accidents and injuries. Background: In order to set up the preventive policies for occupational injuries and illness systematically, the accident analysis by industry should be preceded. To establish more effective policies, it should be done by occupation for persons who work in various kinds of occupation rather than by industry for persons who do in the same occupation. Method: In this study, the 176 occupational accidents and injuries were classified by type of workplace - indoor (inside building) and outdoor (at the top of utility pole, in a manhole, or in the fields) - and also done by operational process involved at the time of the accident. By analyzing the characteristics of occupational injuries and illness by type of workplace and operational process, respectively, this study can be helpful in establishing the preventative policies for occupational accidents and injuries. Results: The characteristics of occupational accidents and injuries by type of workplace showed that there were differences in terms of accident rate between indoor and outdoor on age of the injured, while not on employment-size and work experience of the injured. In addition, the characteristics on accident type, agency of accident, parts of body affected, and operational process between indoor and outdoor workplaces were statistically different each other. Conclusion and Application: The findings of occupational accidents' characteristics can be applied to the establishment of systematic preventative policies for occupational accidents of telecommunications line/equipment workers.

Mouse embryonic stem cell could show an substitutional materials of cells of neuron differentiation, positively increasing their effectiveness in the treatment of nervous symptom. We examined that mouse embryonic stem cells (mESCs) can be induced to undergo neuronal differentiation. After neuronal induction, the phenotype of mESCs changed towards neuronal morphology and mESCs were injected into the lateral ventricle of the experimental animal brain. Transplanted cells migrated to various parts of the brain and ischemic brain injury by middle cerebral artery occlusion (MCAO) increased their migration to the injured cortex. Intracerebral grafting of mESCs mostly improve sensory and motor nervous system of neurological injury in focal cerebral rats.

The ageing problem of the population has been emerging in Korea since 1970's so that it is expecting the elderly 65 years and over among the total population from $4.5\%$ in 1988 to be $6.3\%$ in year 2000. This study was conducted to provide secure policy development in coming years for the aged on medical and health care aspects based on the examining current status of the aged problems and health care policies and systems. The study divided into four parts; The first part examined the medical insurance program and public assistance program of the health services in relation to the aged. The second part emphasized on reduction of medical care cost for the aged. The third part studied the regular health check-up program and health education for the aged. The fourth part examined the chronic disease management programs for the aged and strategies of the health care service quality improvement and specialized programs. The following recommendations made as the results of the study. 1. At present, the medical insurance program and public assistance program for the medically indigent is not appropriate to the elderly because it is a part of general medical insurance program so that Health Security Law for the Aged is proposed. 2. Medical cost will be increased due to the high occupancy rate of hospital beds and long stay of the elderly so that it is recommended to develop an early discharge program, home health care program, Health hospice and an althernative programs. 3. At present, a regular health check-ups for the elderly is not included in medical insurance program so that it is recommended to be included in the insurance program and at the same time health education program thoroughly developed for the aged. 4. To make proper medical and nursing services on chronic diseases for the elderly, it is recommended manpower development, specialized clinics or hospitals, nursing homes and an equivalent long term care facilitices should be established on the community based and a research institutions also to be related to supper the care programs.

From the first application of a thermoelectric module to nowtoday, it has been more than half a century. The application of a thermoelectric module is becoming more and more widely accepted since, people's requirement rely more and more on the efficiency of thermoelectric modules and their reliability become higher and higher. So people pay more and more attention to the thermoelectric module. In Around the world, the more research for into improving the efficiency of thermoelectric modules is focused on the current materials. at present. However, the research of into available materials had has some limitations, and the research of materials had reached a bottleneckthere are limits to current applications. On the other hand, from the production process, if we assembled by materials withoutmodules without any damages and achieve the ideal state of a joint, we can make the a product to maximize performance and have a longer service life. SoTherefore, in this study we will prove the relationship between the any defects inside and the efficiency of a thermoelectric module to improve the quality management and performance of modern thermoelectric modules at present.

The present study attempted to conceptualize Korean typical tastes, flavors and foods and to gather professionals' opinions about the globalization of Korean foods. A total of 23 experts participated in a three round survey using the Delphi technique, which was used to integrate and share the professional ideas of each expert. The survey was categorized into two parts: 1. Korean typical tastes and flavors, 2. Korean typical foods. According to the results, 'hot chili pepper', 'Kimchi', 'soy sauce', and 'garlic' were represented as Korean typical tastes and flavors. Also 'harmonized' was determined to be a type of food that should be introduced to foreigners and, 'sweet' and 'tart' were shown to also be liked by foreigners. In addition, 'neobiani', 'kalbi', 'bibimbap', 'kimchi', 'japchae', and 'neobiani' were categorized as typical Korean foods, foods that should be introduced to foreigners, and foods that would be liked by foreigners. These results showed that appropriate foods should be globalized and R&D should be expanded to determine the preferences of foreigners in terms of tastes and flavors.

This study investigates the nature and patterns of interrelation between the emerging information and communication technology(ICT) and the organization of corporate space, both theoretically and empirically. In this work, ICT is conceptualized not so much a space-adjusting technology as an organizational technology. ICT is considered as a governance technology which is related to coordination function within a firm. Therefore, it is supposed to have a great relevance to the spatial reorganization of functions within a firm. Both questionnaire and case study method are used to gather necessary data from Korean electronics manufactures. The results of this study can be summarized as follow. First, the spatial structure of a firm, which is operationalised as the number and type of spatially separated establishments, is turned out to have a great explanatory power to its adoption of computer networks. Computer networks in muli-locational companies are introduced to overcome the limits of its spatial structure, such as duplication of functions, such as duplication of functions, loss of time spent in proceeding a job between different functional units, and unresponsiveness to the change of market demand. Second, new spatial division of labor and function could be possible through a series of business process reengineering, not through the mere adoption of ICT. Case studies reveal that computer network could help a firm to realize new forms of spatial division of labor, especially in those functions which is mainly based on the flow of information. Such function as ICT management, sales logistics and after-sales service are major parts where a new operational unit has appeared with the help of ICT. From above results, it can be concluded that the interrelations between ICT and organizational space should be approached intimately integrated with the change of industrial structure and it's organizational implications.

Recently, there have been a large number of remodeling (or renovation) works in old buildings in urban areas. Compared to new buildings, environmental risk might be more significant in such buildings where remodeling works are going on, since some parts of the building may still be in service for people. This study was carried out to investigate the impacts of remodeling works on the indoor air quality (IAQ) of a large building (a 22 stories university library). Indoor air monitoring was conducted during and after the remodeling works every two weeks for a one year period, and target compounds included BTEX, styrene, TVOC, carbonyl compounds such as formaldehyde and acetaldehyde. $CO,\;CO_2,\;PM_{10}$, and $PM_{2.5}$. Overall, the IAQ appeared to be recovered within two months after the remodeling works. However, in some places, concentrations of formaldehyde, toluene, xylene. and ethylbenzene showed higher levels even after works than those during the works. The results indicate that painting, glues and office furnitures are major sources of aromatic VOCs and formaldehyde. Therefore, in order to decrease the concentrations of toxic VOCs, the use of environmental-friendly building materials is strongly recommended during the remodeling works. In addition, IAQ control and management scheme (for example, baking the inside of the building) should be taken into consideration before reopening the buildings.

This study tried to develop a basis for quantitative index of working postures associated with WMSDs(Work-related Musculoskeletal Disorders) that could overcome realistic restriction during application of typical checklists for WMSDs evaluation. The baseline data for this study was obtained from automobile manufacturing company(A total of 603 jobs were observed). Specifically, data for shoulder postures was analyzed to have a better and more objective method in terms of job relevance than typical methods such as OWAS, RULA, and REBA. Major statistical tools were Clustering, Logistic regression and so on. The main results in this study could be summarized as follows; 1) The relationships between working postures and WMSDs symptoms at shoulder were statistically significant based on the results from logistic regression. 2) Based on clustering analysis, three levels for WMSDs risk at shoulder were produced for both flexion and abduction were statistically significant. Specific results were as follows; Shoulder flexion: low risk(< $37.7^{\circ}$), medium risk($37.7^{\circ}{\sim}70.0^{\circ}$), high risk(> $70.0^{\circ}$) Shoulder abduction: low risk(< $26.5^{\circ}$), medium risk($26.5^{\circ}{\sim}56.8^{\circ}$), high risk(> $56.8^{\circ}$). 3) The sensitivities on risk levels of shoulder flexion and abduction were 64.0% and 20.6% respectively while the specificities on risk levels of shoulder flexion and abduction were 99.1% and 99.3% respectively. The results showed that the data associated with shoulder postures in this study could provide a good basis for job evaluation of WMSDs at shoulder. Specifically, this evaluation methodology was different from the methods usually used at WMSDs study since it tried to be based on direct job relevance from real working situation. Further evaluation for other body parts as well as shoulder would provide more stability and reliability in WMSDs evaluation study.
