The lobby is the space that contributes the most to conveying the first impression of an enterprise or company that is occupying a building, and enhances the quality of the urban or business environment around an office building. Transparency is the biggest change in architecture since the modern age began, and it is the most important element of the lobby expression methods. Therefore this study was an attempt to understand the expression method of transparency which is expressed in the lobby space of office buildings, and used documentary survey and field survey to analyze it. In the examination of the theoretical background of transparency to make a specific study purpose, and based on an on-the-spot probe document, an attempt was made to grasp the expression method of Visual Transparency and Phenomenal Transparency. The data collected during this investigation was studied and a correlation coefficient. A summary of the findings of this study is as follows: 1) Transparent materials does not appear often in floors. But Phenomenal Transparency material is used in the floor. 2) During the survey it was discovered that Visual Transparency was often used in the walls of each investigated building. Phenomenal Transparency materials are found less in walls than in the floors of lobbies. 3) The expression methods that appeared the most in ceilings among the Visual Transparent expression methods. In the case of Phenomenal Transparency, the highest distribution is seen in ceilings. 4) The result of the analyzation of the correlation coefficient of Visual Transparency and Phenomenal Transparency is as follows: Expression method: There is more than one expression method of transparency, 'Open Sight', 'Light Material' and 'Surface Material' methods were introduced in case of the introduction of 'Transparent Material' among Visual Transparency in office building lobby space planning. If the 'Superimposed Space' method is introduced, then the 'Ambiguous Border' or 'Dual Sight' methods are introduced.

The purpose of this study was to investigate the effect of work factor/home factor on health status in women office workers. This study investigated the relationship of various influencing factors between health status using claims data of the The Fifth Korean Working Conditions Survey sample from 2017. To this end, we employed logistic regression analysis using sample data from 3,115 female office workers. Logistic regression results indicate that influential factors were ages, employment status, satisfaction with the work environment, sex ratios at workplace, economic burden, childcare burden, housework burden. We discussed several policy and academic implications. As women become more active in society, the number of female workers is increasing. If employers improve the health status of female workers, they will benefit from improved productivity in their business. Therefore, improving the work conditions of the those female workers is very important. Also, practical policy considerations should be needed for female workers to strengthen their social capital in order to enhance their status of health.

Objective and Background: Due to increase in Musculoskeletal Disorders (MSDs) relating to computer use, a number of ergonomics recommendations have been proposed in order to tackle this problem. However, some of these recommendations have been conflicting. Method: This study was to survey the VDT (Visual Display Terminal) use of office workers. The subjects were 452 workers at 13 places of business and the data were collected by self-administered questionnaire. Results: As a result, prevalence of self-reported MSDs of all VDT workers was 90.2% and shoulder took up 57.0% and neck 38.3% by symptom part of body. The population of computer use of more than 6h/day was 84.5%, and 33.8% also reported using the VDT 2~3h/day without the rest time. Desktop computer users were 95.6%, and a 17-inch monitor accounted for 42.0% among the desktop users. As a result of satisfaction survey on overall computer work, 21.1% of the total respondents said satisfied, desk complaint was about 24.6%, and chair complaint was 33.4%. Despite the importance of computer environment, satisfaction was from fair to uncomfortable. Conclusion and Application: In conclusion, office workers are prone to the MSDs due to their work environment. Additionally, this study found that task was a significant effect for the majority of dependent variables, and therefore, the improvement of computer workstations work environment is urgent, and the improvement of desk height adjustment, chair seat size (length, width), backrest condition, location of keyboard (mouse) and arm rest is required.

The purpose of this study is to evaluate of the outdoor thermal environment by building scale and block type as variable factors. In this study, 18 cases of office in central business district that have different condition are compared about their surface temperature, HIP(Heat Island Potential), and MRT(Mean Radiant Temperature). They are simulated with 3-dimension numerical simulation software named Hoyano-model. The output results contain visualized distribution chart and numerical data. The results of evaluation are as follows. (1)The surface temperature of the building becomes higher as building coverage ratio is higher but floor area ratio is lower. In same conditions, unified block type is maximum $3.2^{\circ}C$ higher than divided block type. (2)HIP shows different daily pattern as block type. During daytime, divided block type is much higher than unified block type but after sunset, it is changed. (3)MRT shows different distribution pattern as sunlight moves expecially at noon. (4)As the results of this study, cases that have high floor area ratio condition show lower surface temperature by tendency to stay low indoor temperature in office building and big rate of windows on building surface.

As the smartphone and mobile environment develop, the time and space constraints for individual work performance are disappearing. Companies can reduce costs and expand their business quickly through cloud computing. As the use of various cloud expands, the boundaries of users, data, and applications are disappearing. Traditional security approaches based on boundaries (Perimeter) are losing their utility in the cloud environment. This paper describes the limitations of existing network access control (NAC) in a cloud environment and suggests network security technology that complements it. The study explains the SDP and combines SDP(Software Defined Perimeter) to overcome the limitations of NAC, while at the same time explaining its role as a new framework for supporting the cloud environment. The new framework proposed in this paper suggests a software-based network security solution that supports physical and software parts, providing identity-based access control, encrypted segment management, and dynamic policy management, not IP-based.

This study surveyed how retirees' evaluation of starting food service business affects the effectiveness their new business and quality of life, based on personal factors such as entrepreneurship and business-starting capability and environmental factors by using questionnaires. Bootstrapping was carried out in order to find out factors affecting rapidly changing new business environments and retirees' initial intent to start a business so as to verify basic hypothesis about relation between retirees' evaluation of starting food service business (social, economic, and psychological effects) and the effectiveness of their new business and quality of life and confirm whether the effectiveness of the new business acts as a medium between the evaluation of starting food service business and quality of life. In addition, PLS-MGA was performed in order to verify whether the correlations among test factors can be varied according to the kind of job the target retirees had. Having examined the basic thesis, it was found that social and economic factors had significant positive effect on the effectiveness of the new business, and social and psychological factors had significant positive effect on the quality of life. Having analyzed whether the effectiveness of new business acted as a media between evaluation of starting food service business and quality of life, there was no significant effect as a medium. Having studied whether the kind of job of the retirees controlled or affected the relations among evaluation of starting food service business, effectiveness of new business and quality of life, the results were as follows: in the office job retiree group, the greater economic factor led to increase of effectiveness of new business, while social and psychological factors influenced the quality of life; In the physical labor group, the higher social factor resulted in higher effectiveness of new business, which showed significant positive effect on the quality of life. Having researched about which element is considered to be most important in starting food service business, the most important element was found to be dish/menu, followed by staff management, accounting management, business management, and service education. Having analyzed relation between accomplishment and important consideration for starting food service business, "managers with entrepreneurship," "appropriate distribution of time to prepare for starting business," and "operation of practical field education programs" showed higher importance compared to the degree of satisfaction, so it is needed to more concentrate on the above matters. This study intends to raise retirees' awareness of starting business and help them live better life based on the analysis results, and further suggest detailed mechanism and specific operations of factors affecting retirees' decision making on starting business, such that they can use the information as basic materials to make better choices that can lead to successful business.
