Risk assessment considers the situations and characteristics of the exposure environment and host. Various physiological variables of the human body reflects the characteristics of the population that can directly influence risk exposure. Therefore, identification of exposure factors based on the Korean population is required for appropriate risk assessment. It is expected that a handbook about general exposure factors will be used by professionals in many fields as well as the risk assessors of the health department. The process of developing the exposure factors handbook for the Korean population will be introduced in this article, with a specific focus on the general exposure factors including life expectancy, body weight, surface area, inhalation rates, amount of water intake, and soil ingestion targeting the Korean population. The researchers used national databases including the Life Table and the 2005 Time Use Survey from the National Statistical Office. The anthropometric study of size in Korea used the resources provided by the Korean Agency for Technology and Standards. In addition, direct measurement and questionnaire surveys of representative samples were performed to calculate the inhalation rate, drinking water intake, and soil ingestion.

The library manager's communication ability can influence organizational management because the types and ways of organizational management is carried out can be determined by the manager's communication ability. In that, this study intends to examine the influence of the library manager's communication ability on job performance and role-conflict of the library staff. To do so, on top of the conceptual framework of communication and the library as an organization, this study builds theoretical underpinnings on the library manager's communication ability, job performance and role-conflict of the library staff. Using a questionnaire survey method, this study surveys 127 library staff from 8 public libraries in Seoul, statistically analyzes the response through the SPSS20 statistical package, and examines the relationship between and among the variables. Based on the analysis, a discussion on the influence of the library manager's communication ability on job performance and role-conflict of the library staff follows.

The aim of this research is to compare the attitude toward the special needs of dental staffs between the special dental clinic (SDC) and the general dental clinic (GDC). Surveys were done on 21 dental staffs (7 dentists and 14 dental hygienists) of SDC and 47 dental staffs (10 dentists and 37 dental hygienists) of GDC. Attitudes were rated on a questionnaire with the five-point Likert scale. Mann-Whitney test was utilized for statistical analysis. In SDC, more female dentists and dental staffs who have relatives with disability were working. Dental staffs of SDC showed that the more experience they had, the more positive attitudes toward the communication with the patients with special needs (p<0.05). Dental staffs of SDC represented more active attitudes toward the oral health promotion, treatment, research and volunteering (p<0.05). In conclusion, dental staffs who have personal motivation were working in SDC and the experience of dental treatment to the patients with special needs influenced the dental staffs' attitudes toward them. In future, a research about the attitude toward the disabled with more exact scale should be followed.

This study proposes a methodology to analyse social networks among participating design engineers during product development projects. The proposed methodology enables product development managers or the participating design engineers to make a proper decision on product development considering the performance of participating design engineers. It considers a product development environment where an integrated product data management (PDM) system manages the product development data and associated product development processes consistently in its database, and all the design engineers share the product development data in the PDM database for their activities in the product development project. It provides a novel approach to build social networks among design engineers from an operational product development data in the PDM database without surveys or monitoring participating engineers. It automatically generates social networks among the design engineers from the product data and relationships specified by the participants during the design activities. It allows analysts to gather operational data for their analysis without additional efforts for understanding complex and unstructured product development processes. This study also provides a set of measures to evaluate the social networks. It will show the role and efficiency of each design engineers in the social network. To show the feasibility of the approach, it suggests an architecture of social network analysis (SNA) system and implemented it with a research-purpose PDM system and R, a statistical software system. A product configuration management process with synthetical example data is applied to the SNA system and it shows that the approach enables analysts to evaluate current position of design engineers in their social networks.

This paper uses Preliminary Surveys of Game User Panels conducted in 2019 to examine how social relations that young game users held affect game use. In particular, we analyzed how social relations of youth affect adaptive and maladaptive usage of game. According to the statistical results, the quality of the relationship between users and parents and that of the relationship between users and their friends do not have consistent effects on the degree of adaptive and maladaptive game use. Also, the results suggests that game-related information can play as a double-edged sword for young game users by reinforcing the degree of adaptive and maladaptive game use. The results implies the possibility of interaction between adaptive and maladaptive game using behavior as an interpretative framework in social context rather than mutually exclusive mechanisms.

Purpose: This study aimed to develop an instrument to assess the quality of childbirth care from the perspective of a mother after delivery. Methods: The instrument was developed from a literature review, interviews, and item validation. Thirty-eight items were compiled for the instrument. The data for validity and reliability testing were collected using a questionnaire survey conducted on 270 women who had undergone normal vaginal delivery in Korea and analyzed with descriptive statistics, exploratory factor analysis, and reliability coefficients. Results: The exploratory factor analysis reduced the number of items in the instrument to 28 items that were factored into four subscales: family-centered care, personal care, emotional empowerment, and information provision. With respect to convergence validation, there was positive correlation between this instrument and birth satisfaction scale (r=.34, p<.001). The internal consistency reliability was acceptable (Cronbach's alpha =.96). Conclusion: This instrument could be used as a measure of the quality of nursing care for women who have a normal vaginal delivery.

The rapid growth of Korean-style buffet in recent years has increased the size of corporate investment. Under this circumstance, businesses make various marketing efforts while highlighting the features and advantages of their brands. Against this backdrop, this study aims to understand which space branding has been applied to the Korean-style buffet through case studies and to propose a method of application of space branding to increase sales in an effective manner in the future. First, the research is theoretical examination and case studies with focus on the characteristics of expressions of Korean-style buffet space branding. Basically, upon completion of examining the concept and the characteristics of expressions of the Korean-style buffet and analyzing the concept of space branding, the components of space branding have been reconstructed based on preceding studies on space branding and then have been applied to each brand space. Also, the hands-on experience of the characteristics of expression of the Korean-style buffet with space branding incorporated in it and prepared a checklist via visual inspections. And then, the field surveys based on these examinations and took approach of drawing a conclusion based on the results analysis conducted by using the SPSS statistical program. Through preceding studies, the three components of space branding, that is, sensory element, emotional element, and cognitive element have been reconstructed before proceeding with this study, which has obtained five major findings as a conclusion. First, the sensory element should be given elements differentiated enough to attract consumers' attention along with a sustainable effort to have brand image imprinted in their mind. Second, in terms of emotional element, the study has found that the brand experience oriented toward interest and participation results in higher utility frequency. Third, the study has found that the cognitive element should seek consistency in communicating with consumers with focus on face-to-face contact on the display in space. Fourth, it has been found that arranging independent spaces is necessary to attract consumers' participation. Finally, the study has identified in which location area of buffet the sensory, emotional, and cognitive elements have placed a significant weight.

Recognizing the ecological importance of forest gap formation for forest community structure, we examined the differences in species diversity between forest gaps and closed canopy areas for trees and shrubs in three developmental stages (seedling, sapling I, and sapling II) in a typical mixed broadleaved-Korean pine forest. We randomly placed 100 sample plots ($2{\times}2m$ for seedling and sapling I, and $5{\times}5m$ for sapling II) in forest gap and closed canopy areas of a 9 ha permanent sample plot for vegetation surveys of plants of each developmental stage in each habitat type. Even though the formation of forest gaps encouraged the occurrence of gap-dependent species and increased overall species diversity, there were no significant differences in species richness among the three developmental stages for both tree and shrub species (p>0.05). Comparing the two types of sites, statistical tests revealed no difference in species richness for trees, but highly significant differences (p<0.01) between forest types for shrubs for seedlings and sapling I, but not sapling II. Analysis of variance test indicated that there were no significant differences in species diversity among the three developmental stages of tree species (p>0.05) for both Simpson and Shannon indices. The variance for shrub seedlings was significantly different between forest gaps and closed canopy areas, but not for sapling I and sapling II. The analysis showed that the species diversity in forest gaps was significantly different from that of closed canopy areas for seedling and sapling I (p<0.01), but not for sapling II (p>0.05).

Librarians, who provide the public with library services at public libraries, are employees whose jobs are often require emotional labor. The emotional labor of librarians working at public libraries can result in stresses caused by the discrepancy between the library's emotional requirements and the librarian's personal emotions, which may influence organizational effectiveness, such as organizational commitment and job satisfaction. In that, this study intends to examine the influence of emotional labor on the organizational commitment and job satisfaction of librarians working at public libraries. To do so, based upon the conceptual underpinning through literature reviews of librarians working at public libraries and emotional labor, this study constructs a theoretical framework of organizational commitment and job satisfaction of librarians. Using a questionnaire survey method, this study surveys 238 public library staff from 33 public libraries in the Seoul metropolitan area, statistically examines the response through the SPSS20 statistical package, and analyzes the relationship between and among the variables. Based on the analysis, discussion on the influence of the emotional labor on organizational commitment and job satisfaction of librarians working at public libraries follows.
