This study is on the spatial composition of accommodation area in accommodation barge. The accommodation barge which is used as living facilities for offshore plants' workers can be classified into Accommodation Work Barge, Accommodation Pipe Lay Barge and Multi-purpose Accommodation Barge. We study on the spatial composition of accommodation area in Accommodation Work Barge, most frequently used, through analyzing G.A drawings of the barges. The spatial composition has great influences into the convenience and amenity for workers' daily life in the accommodation area of accommodation barge. The spatial composition of accommodation area shows many characteristics not in horizontal arrangement on any deck but in vertical space arrangement on layers of decks. The particular types of vertical space composition can be classified into 'Centralized Type' and 'Dispersive Type'. These two types will be the basis of space planning for new accommodation barge.

This study aims a comparative analysis of social stratification in the Great Seoul area using two types of population. One type of population is a resident population(常住人口), and the other is a daytime population주간인구(晝間人口). In most demographic studies, only resident population have been considered. There has been less attention to daytime population. However, a resident population have a character of night population야간인구(夜間人口). In fact, most people move and work in the areas where they do not live in everyday life in the contemporary period, which indicates that the concept of a daytime population is more significant than that of a resident population. This study reveals that a number of people, on the one hand. come together to the downtown area to work or study while they live in other areas. On the other hand, resident population in downtown area do not move so much. When we analyze the social stratification structure of the Great Seoul area using a resident population, we find that the resident population of downtown area consist of those of low social status. On the contrary, the daytime population of downtown area in Seoul consist of those of high social status. This means that most people of high social status live in the southern area of Seoul or outside Seoul, but make a living in downtown area in everyday life. From this study, we find that the concept of a daytime population is as important as that of a resident population. The more residence becomes separate from work place, the more the significance of the concept of a daytime population grows in making policy as wall as in demographic studies. This study implies that we need to pay more attention to the concept of daytime population in demographic and sociological Studies.

This study analyzes the reality of the overall operating system, such as recognition and satisfaction with school field support work system of the Education Facilities Management Center, recognition level of restructuring of work areas, and the direction of improvement for school facility maintenance support in various types of future learning environments. To analyze the problem of this study, a survey was conducted on 290 education administrative officials in Gyeonggi-do. First, school site awareness and work performance satisfaction of the Educational Facilities Management Center were evaluated as "below average," and it is necessary to improve the qualitative work area that is practically helpful to schools. Second, in the area of organizational operation, it is desirable to avoid simple tasks with a low evaluation of "below average" and to switch to an operating system that improves efficiency. Third, the need for the facility environment area (professionalism, safety) was the highest, but the center's ability and work processing level were evaluated very low as "below average," so it is urgent to improve the center's capacity. Fourth, in the area of social and educational policy change, the center received a high score for the need for access from the perspective of a learning environment linked to future education. Therefore, a policy review on the restructuring and improvement of work areas suitable for this is necessary.

Drawing and normalizing are efficient means for controlling strength, fatigue and machinability of free machining steel. Normally strength and machinability are conflicting properties which need to be optimized. In this study, the effects of normalizing temperature and reduction of area on strength, fatigue and machinability were investigated. Fine grains were generated at lower normalizing temperature and fatigue life was increased with decreasing grain size. Matrix was work hardened and elongated with increasing reduction of area. Inclusions also were elongated and cross-sectional area of inclusions along drawing axis was decreased. The effects of work hardening and grain size on fatigue life were significant, but only work hardening affected machinability. Shape and distribution of inclusions after drawing had little effect on fatigue life and machinability.

We tried new interpreting about the work of art in this paper. The work of art respects the intention of the artist to make it and interprets intention until now. After critics distinguish by a period, an area that they set to philosophical thought which is the time and interpreted. We set to each one subjectivity and interpreted between artist to make the work of art and appreciator. But in this paper, we tied various criteria which appreciates the work of art. We tried so that we presented the intimacy each other newly. Otherwise we tied with the subjectivity of the individual and are the try to be an objectification low through statistical technique. We looked into the culture and art in the introduction and explain the discussion about the work of art interpreting which the main subject. We set the category 6 area, and explain an each criteria explanation and assessment method. We tried to propose new interpreting as the intimacy to be multi-variate data analysis result of the assessment analysis.

The purpose of the study is to provide basic data on the public health management in the industrial work places, and some implications on the public health education related to workers self care capacity of their own health. To achieve this purpose a questionnaire was provided to 332 workers during February 11-28, 1993. This was do in Changwon-shi Geojeoi-kun, Chungmoo-shi, Jinjoo-shi, of Kyeongnam province. Through the analysis of the survey results, a relationship was deduced between worker's general characteristics and basic elements of health management in the work place. The main results of this study can be summarized as follows : 1. In the knowledge area special health screening received the highest score 3.18. While the educational program scored the lowest .85. In the Attitude area the highest score was achieved in the affirmative attitude to the time consumed by health checks (3.28). The lowest by the management of health checks(1.53). In the Practice area, participation in health checking is the most active (3.44) , and public health education is the least active (0.95). 2. The differences of knowledge by workers' general characteristics is statistically significant in the work sector (P<.05), age (P<.05), sex (p<.001), marital status (P<.001), and prior career(P<.01). But in Attitude general characteristics are not significant factors. In the Practice area, did have a statistical significance, work sector (p<.001), age (p<.001), sex (P<.05), marital status (p<.001) and work career (P<.001). 3. The total difference by workers' general characteristics has a statistical significance only in the case of marital status (P>05). The note of married workers is higher than that of single workers. 4. The correlation between any two of Knowledge, Attitude, and Practice do have a statistical significance (p<.001).

The better industry develops, the more spaces need but in the limited area. Most building become larger and more complicated if the more spaces need in the constant area. And this leads to do underground work in long period generally six(6) months for 6 basement stories due to the selection of TOP DOWN technique. Working environment in this underground area can be problems and should not be overlooked, because air quality in underground spaces become quickly worse. Recently, department name to control construction safety has been changed to ENVIRONMENT & SAFETY TEAM from SAFETY TEAM. This means that it is very important to control against environmental condition at site so much. Overall construction work as well as underground work should conform to the requirement of working environment, particularly against inhabitants around the construction area. Strut protection, one of earth protection method, in case to 40m long strut may become weaker due to thermal stress or its longitudinally compressive strain and the another one, earth anchor protection may not be applied to the site In case of encroaching on vertical underground borderline because of regulation to prohibit it. It is necessary that TOP DOWN technique should be introduced in order to solve the external and internal problem of the site such as difficulty level of the work, potential danger with excavating depth, and shortening workperiod. It is needed that improving way of working condition should be shown and simplified computer simulation program should be also provided for checking pollution level & ventilation, excluding of lighting problem here. Results measured with conformance to the Regulation for Working Environment Measurement, enforced by Ministry of Labor have been applied to the computer program developed here. Sample air taken at unit workplace which was considered as exposing condition of pollutant at breathing point and within a range of behavior of the workers, Identified exposing group in underground work, using Moded Flow Life Finally, three types of ventilation system, type I with blower & ventilator, type II natural supply with mechanical ventilation system, and type I mechanical ventilation with Drivent Fan Unit System are selected for this study.

Purpose: The main purposes of this study are to describe the organization effectiveness and to investigate the effects of dental technicians' work ethic on job satisfaction, organization citizen's action, and organizational commitment. Methods: A total of 300 dental technicians working at dental laboratories in the Daegu area were randomly selected and surveyed, 298 of them were used for the statistical analysis. Results: The work ethic sub-items, such as industry, work centrality, morality, time save, independence, and relation with co-worker are independent variables. The organization effectiveness subi-items, such as job satisfaction, organization citizen's action, and organizational commitment are dependent variables. Sociodemographic variables are used for control variables. Findings are as follows: First, in terms of dental technicians' work ethic, the level of relation with coworker was the highest, and work centrality was the lowest. Second, in terms of dental technicians' organization effectiveness, the level of citizen's organizational action was the highest followed by organizational commitment and job satisfaction in order. Third, the effects of industry, work centrality, time save, relation with coworker, and morality showed statistically significant relationships with organizational effectiveness. Fourth, the effects of industry, work centrality, time save, relation with co-worker, and morality statistically significant relationships with job satisfaction. Fifth, in terms of organization citizen's action, the effects of industry, work centrality, and time save were statistically significant. Sixth, work centrality, time save, relation with coworker, and independence were statistically significant with organizational commitment. Conclusion: Some policy implications for the improvement of organizational effectiveness are introduced and discussed. Dental technicians are required to have vocation and work ethic for themselves and the organization, and by doing so, they may contribute to the improvement of national oral health. Policies and educational programs, which can support them may be necessary.

To know the effect of construction works at the Busan New Port on the activity of otters, changes in the distribution of spraints were investigated at 5 areas(I-V) composed of 16 locations in 12 islands from 2003 to 2011. There were significant differences among the density of spraints at each area(P=0.0502), at each year(P=0.0040) and at each area during the study period(P=0.0005). The densities of spraints in the areas II (P=0.000) and IV (P=0.012) were significantly different according to whether the construction work was carried out or not at each area. It was found that the density of spraints in each area was affected by the disturbance with construction works or other factors inside and/or outside the area. The average density of spraints of the 5 areas had changed according to the process of the construction works as follows. In 2003-2005 when the construction work was proceeded mainly at the area IV, the average density of spraints of the 5 areas as well as the density in the area II increased annually, whereas the densities in the other 4 areas were low and relatively constant. This fact suggests that otters might have moved into the area II from outside the study area. In 2006-2009 when the construction works were carried out on a larger scale at the areas I, II and III, there was a little decrease in the average density of spraints during the latter two years, suggesting a little decrease in the activity of otters in the study area. As regards the density of spraints at each area, it decreased considerably in the area II, but increased fairly in the areas III and IV. Accordingly it was indicated that otters in the area II where the construction work was carried out since 2006 might have moved into the area IV with no work, and otters inhabiting the Jeodo, Geoje city, where the construction work was carried out at that time, might have moved into the area III with no work at the sea shore. In 2010-2011 when the construction works were conducted at all the areas on a fairly large scale, the average density of spraints of the 5 areas as well as the densities in the areas II, III and IV, decreased considerably compared to the those in the year 2009. This fact clearly indicates that the number of otters decreased owing to the multiple simultaneous works in this period. In conclusion, otters must be affected by the construction works at the study area, and their numbers might be decreased mainly due to the multiple simultaneous works, as well as by the long-term works resulting in the decrease of seashore, marine pollution, and reducing prey available.
