Objectives: The objective of this study is to evaluate the exposure of VOCs and effects of the chemicals on the nail technicians whose works in a nail shop. Methods: For four month from May to August in 2016, we measured twenty-two kinds of VOCs in ten nail shops and carried out health examinations on thirty-four workers in there. Results: The TVOC concentration in indoor air of nail shops is $0.487mg/m^3$ at a minimum and $33.236mg/m^3$ at a maximum where it consists of 70.5% of Ketones, 25.4% of Alcohols, 2.6% of Esters, 0.8% of Aldehydes and 0.7% of Aromatics. The VOCs concentration during nail art works shows an increase in average ratio 1.8 compared to the concentration of indoor air quality and also the concentration of Isopropanol rose with 3.2 of the highest ratio. The results of Spearman correlation between TVOC concentration in indoor air and environmental factor was like that has significance level of correlation(${\rho}$<0.05, r=0.682) in case of number of customers per day, but the other factors were not meaningful in correlation. Correlation between VOCs and medical check-up items was like that has positive significance level(${\rho}$<0.01, r=0.638) between isopropanol and GPT, but the others have not meaningful. The exposure level of VOCs was not exceed the criteria exposure level 1 of working environment measuring method which announced by labor ministry in all ten nail shop indoor air quality. Conclusions: In this study although it was not significant correlation between harmful substances and medical check-up items in the nail shop indoor air quality, it is necessary to do more ventilation and to install exhaust facilities because of existing high VOCs concentration in the nail shop indoor air.

The purpose of this paper is to determine the percentage of body fat by measurement of skin-fold thickness of the triceps and the subscapular area to investigate the relationship between the daily energy intake and expenditure among obese women and nonobese women based on the percentage of body fat and age. This survey included 422 females in Cheju. 1) The age distribution of the 422 females surveyed was : 26.8% were in their 20's, 20.6% in their 30's, 21.3% in their 40's, 19.0% in their 50's and 12.3% were above 60 years of age. The 422 females consisted consisted of 78% housewives, 12.8% college student and 9.2% single working women. 2) The average height and weight of the surveyed women were respecitively 159.0$\pm$4.2cm and 56.0$\pm$7.2kg, the percentage of body fat of the surveyed women was 24.8$\pm$9.8%, and the BMI of those surveyed was 22.7$\pm$2.7. If higher than 30% body fat was defined as being obese, 15.6% of the surveyed women were assessed to be obese. 3) Total daily food consumption and energy intake of the group of women aged 60 and older was significantly small. Food consumption and nutrient intake of obese women was greater than that of the nonobese group, but not significant. Carbohydrate intake of the obese group in their 40's was significantly higher than the nonobese group. Total food consumption, energy and carbohydrate intake of the obese group in their 50's was significantly higher than the nonobese group. Vegetable intake of the obese group in their 60's and older was significantly higher than the nonobese group. 4) The total time of physiological activity of women aged 60 and older was significantly higher than for the other age groups and the total work time was significantly lower. The total work time of women in their 20's was not lower than the other groups. Considering the low energy expenditure of physical activity for women in their 20's, they appeared to have light activity. However, there was not a significant difference in the physical activity time among middle aged women groups(from 30 to 50). The entire energy expenditure of the obese group was greater than the nonobese group. However, the energy expenditure per body weight in the obese group was significantly less than that of the nonobese group in terms of the basal metabolic rate in consideration of the fat free mass. 5) There was a positive correlation between the percentage of body fat and the factors of age, sleeping time, total time of physiological activity, housework time, time spent watching TV, energy expenditure, energy intake, carbohydrate and cereal consumption. On the other hand, the percentage of body fat was negatively correlated with energy expenditure per body weight based on the basal metabolic rate in consideration of the free mass.

The purpose of this study is to verify the effect by developing and applying a new program for improvement of creative problem solving ability and collaborative ability. Development of a sewing practice program was performed through the ADDIE model. The subjects of the study were 1^st grade middle school students and the research plan of the study was pretest-posttest control group design. The study method was performed by mixing the quantitative and qualitative analysis methods. Results of this study are as follows. First, the students in the experimental group showed higher creative problem solving ability than the students in the control group, but the difference was not significant at the 5% significance level. Qualitative analysis results indicated that creative problem solving ability is closely related to learning experiences involving the 'generation of diverse ideas', 'rebirth of creative ideas', 'self-directed learning plan', 'active problem solving', 'immediate feedback'. Second, the students in the experimental group showed a significantly higher level of collaborative ability than the students in the control group. This demonstrated that the program developed in this study had an effect on fostering the collaborative ability of middle school students. It was found that collaborative ability is closely related to learning experiences involving 'forming a positive atmosphere', 'continuous interaction', and 'working together'.

According to the survey by the Ministry of Unification, 28,133 live in South Korea as of september 2015 and the number has been steadily increased. It is interesting to note that the majority of defectors were women. Statistics say that the total of women defectors was 1,138 in 2002 and consisted of 55.5%. But the number increased to 2,706 in 2011 and consisted of 70.5%(Wikipedia, 2015). Most of them have trauma, because they experienced terrible events like prostitution, sexual abuse, domestic violence, etc. while they were living in South Korea. They had to get over a lot of challenges they never expected. They had to do whatever they need to do for their survival in South Korea as well as in North Korea. Objectives: This study focuses on identifying the psychosocial resources available for them in order to help them out living here. Method: For this purpose, this study conducted unstructured in-depth interviews with four women defectors from North Korea. Their age bracket is between the ages of 50 and 58 and they have stayed over five years in South Korea. They were recommended by social welfare workers, who had dealt with them over 20 years. For the reliability of this study, the three methods were performed such as three-month close relationship, three-person triangular verification, and diversification of resources-the field notes and observation notes. Results: As a result of this study, the resources may be labeled into three main clusters of themes such as 1) Self-Preservation - 'Self-Love', 'Family-Attachment', 'Share the Goods', 'Live in Harmony', 'Avoidance of conflict'; 2) Self-Conquest - 'Endurance', 'Earnestness and Effort', 'My own Activities', 'Chat', 'Put Down', 'Appreciation and Optimism'; 3) Self-Presence Awareness - 'I was a Precious Daughter', 'I am Mother'. Also there are thirteen sub categories to be considered. Conclusions: This study focuses on identifying how women defectors have used or can use the psychosocial resources available for them, rather than what they have struggled with. It is meaningful to identify in a positive light that this study provides how they have adjusted to a totally different context for their survival and what psychosocial resources they have used. This study can give an idea about how they may receive proper and practical help from the government programs in order to become better used to new living circumstances in South Korea. As well, this study can provide meaningful criteria and guidance with family life educators for women defectors and social workers working in counseling and social welfare areas. This study contributes to better understanding about how they are using these psychosocial resources.

Forest in the our country is in the age that needs positive operation in order to foster economical forest. Multiple operations for making valuable forest should be conducted steadily and timely from afforestation to harvesting. In order to execute these kinds of forest operations, the construction of skid trail network that can be effectively used as a pathway for forestry machine and working space is necessary. To investigate facility effect of skid trail network, we executed the location of skid trail network through centroid method by GIS for 50ha of harvesting workplace in mechanized model forest located in Hongcheon, Gangwon Province. As a result of this research, skid trail density in this area changed from 79m/ha with current method to 42m/ha with improved method. It appeared that skid trail density with improved method is nearly half of current method even though the cutting area is the same as the current cutting area. Also, skidding distance changed from 117m with current method to 57m with improved method. It appears that skidding distance with improved method is nearly half of current method even though cutting area was enlarged in adjacent tending cutting area.

As the construction production system is reorganized as part of the construction industry innovation plan, direct construction is expanding. According to this trend, this study analyzed the impact and problems of the expansion of direct construction through the position of the construction industry and a study of foreign cases. In addition, by diagnosing the impact of the measures to expand direct construction from various aspects, countermeasures were suggested to suitably apply the direct construction mandatory system. Also, for each alternative, effects and problems were evaluated through interviews with experts in policy/administrative and architecture fields. The alternatives for expanding and improving the efficiency of the direct construction mandatory system derived from this study are four items: granting the discretion of the client, differentiation by scale of construction, utilization of construction guarantee system, and introduction of flexible working group leader system. As a result of the expert interview, all of them were evaluated to have a positive impact directly and indirectly on the expansion of direct construction. This study contributes literature to the application of the direct construction mandatory system by examining the current status of direct construction, and suggests a direction for expanding direct construction through deduction of alternatives for applying the direct construction mandatory system and expert evaluation.
