As the Long-life certification system is recently introduced in the Housing Law in Korea, it is expected that an application of the lightweight wall panel will be increased in apartment construction as the main wall system. However, the performance criteria for lightweight wall is in the early phase of its action. Therefore, it is necessary to establish the performance criteria properly by investigating performance requirement in the user's perspective. The purpose of this study is to identify of the weight of the required performance items for the lightweight wall in apartment house. To analyze the priority in the performance, an interview survey is performed; after monitering the test-bed of the lightweight walls, user and experts evaluate the performance requirements. The weight of the performance requirement is developed by AHP method.

The purpose of this study is to analyze the cognitive demands level of the description about 'pure substance and mixture compound', 'ionic compound', 'molecule' on the 'science2' textbooks by the 2007 revised curriculum. The three types of Curriculum Analysis Taxonomy have been used to analyze the cognitive demands level of those contents on the 6 kinds of 'science2' textbooks. The first, the cognitive demand level about 'pure substance and mixture compound' on many textbooks is a late concrete operational stage because of class inclusion and hierarchical classification. And the descriptions as 'pure substance is conserved even when mixed with other pure substance' is a early formal operational stage. The second, the cognitive demand level about 'ionic compound' and 'molecule' is a early formal operational stage, because of "Formal modeling is the indirect interpretation of reality by deductive comparison from a postulated system with its own rules" and "Atoms have a structure". The third, the terms as 'ionic bonding', 'ionic compound', 'chemical formula', 'covalent bonding', 'covalent compound', and 'molecular formula' have been used on many 'science2' textbooks. Those terms would be used later on 'chemistry I' and 'chemistry II' in senior high school but not even 'science3' and 'science'.

There is a high demand for off-base dwellings around Camp Humphreys in Pyeongtaek in accordance with the USFK base relocation project, but their residential planning needs to reflect their requirements. On the other hand, no studies that examined their requirements directly have been found. This study examined the requirements of USFK stationed in Camp Humphreys to identify their requirements. In general, residential planning requires a determination of the demand-based location and size, identification of the facility elements required for the site plan, and analysis of detailed architectural planning elements required for the building plan. Among these, preference analysis of the off-base dwelling demand, location, and site planning elements were performed in this study, and the architectural planning elements were left as following studies. The analysis showed that the demand for off-base dwellings is high, rental houses are preferred, and the commuting time is the most important factor in the location. In addition, while enjoying urban convenience, the location of the foothills near nature is preferred, the importance of the orientation is low and living with Koreans is not a problem. In addition, the demands for exercise facilities in the complex are relatively high.

Environmentally Sound and Sustainable Development (ESSD)" is a key word in recent years. The construction industry, have put a great influence on ergonomic and sustainable environment. Recently, "green building certifications", such as Indoor Air Quality (IAQ) and eco-friendly material regulation have been established. With this regard, new construction and aged-housing remodeling projects are required to meet these certification criteria. Apartment residents have great concern on eco-product, since many cases are reported that Sick Building Syndrome is caused by toxic substance from building materials. Aged-housing remodeling construction has a unique characteristic in that the residents are already determined prior to construction execution. Therefore, the analysis of resident's need for building materials in aged-housing remodeling is relatively easy compared to new building construction. As such, it is very important to analyze their preferences for eco-friendly materials prior to project execution. The purpose of this study is to find the needs of residents and priority of their needs. Based on their needs and priority, this paper provides a new strategy in using environment-friendly materials and maximizing their satisfaction level when aged housing remodeling is constructed. In addition, this paper provide new criteria in selecting new developed environmental materials in remodeling projects for the purpose of improving the safety and health level in construction industry.

This study analyses the needs of workers at foreigners-only casinos in Korea on English for Specific Purposes (ESP). It also examines the most ideal English instructor for them and the motivations for their learning English. A total of ninety-nine casino workers in Seoul and Busan participated in the survey. Of the four language skills, English speaking is the most necessary area for them to learn and listening is the second. The most difficult part of communicating in English for them to learn is also speaking, followed by listening. This indicates that the area that they need to study and the area in which they have difficulty communicating in English have the same ranking. The participants in the marketing department had the longest working hours in English, and they were significantly different from those in other departments. Regardless of their departments, the participants responded that speaking is the most necessary area to learn English. They mentioned that their biggest motivation for learning English is self-realization, followed by smooth work. The most ideal English instructor was a Korean instructor with casino working experience, followed by a bilingual Korean instructor. This showed their preference for Korean English teachers with casino working experience. This study might be meaningful since it provides information on a new field, casino workers, by analyzing their needs on ESP. It is suggested that this may contribute to setting the direction of English curriculum for casino workers in the future.

Modern systems have become more and more complex due to the ever-increasing user requirements and rapid advance of technology. As such, the frequency of accidents due to system design errors or failure has been increasing. When the damage incurred by accidents to human beings or property is serious, the underlying systems are referred to as safety-critical systems. The development of such systems requires special efforts to ensure the safety of the human beings operating them. To cope with such a requirement, in this paper an approach is employed in which we consider safety starting from the conceptual design phase of the systems. Specifically, a systems design method that can detect functional failure is proposed by utilizing meta-models and M&S methods. To accomplish this, the safety design data from international safety standards are first extracted and also a meta-model is generated using SysML (systems modeling language). Then, a SysML-based system design method is proposed based on the use of the developed meta-model. We also discuss how the safety requirements can be created and verified using a simulation method. Finally, through a case study in automotive design, it is demonstrated that the detection of a functional failure and the verification of a safety requirement can be accomplished using the SysML-based M&S method. This study indicates that the use of meta-models can be useful for collecting and managing safety data and that the meta-model based M&S method can make it possible to satisfy the system requirements by reducing the design errors.

As the functions and technology of IT security solution has been diversified and complicated, it is necessary to make the functions standardized. The common criteria (CC) evaluation and certification scheme was introduced with this background in 2000. For over 10 years after the introduction of CC evaluation and certification scheme, many security solution vendors have developed functions following the security functional requirement in CC. Most of CC evaluators and developers think that CC has helped to enhance the security of the solution. So, it is a right time to prove the affirmative effects of CC in quantity. In this research, we compare two cases, the security status of the solution before and after the experience of CC evaluation, and analyze the results. We made the questionnaire for the domestic solutions vendors. We show that CC has made positive effects on the security of the solution quantitatively using statistical analysis. This research is meaningful security enhancement of domestic security solutions.

The main purpose of this study is to provide a basic information for the seismic capacity evaluation and the seismic design of low-rise reinforced concrete (RC) shear wall buildings, which are comprised of a pilotis in the first story. In this study, relationships between strengths and ductilities of each story of RC buildings with pilotis are investigated based on the nonlinear seismic response analysis. The characteristics of low-rise RC buildings with pilotis are assumed as the double degree of freedom structural systems. In order to simulate these systems, the pilotis is idealized as a degrading trilinear hysteretic model that fails in flexure and the upper story of shear wall system is idealized as a origin-oriented hysteretic model that fails in shear, respectively. Stiffness properties of both models are varied in terms of story shear coefficients and structures are subjected to various ground motion components. By analyzing these systems, interaction curves of required strengths for various levels of ductility factors are finally derived for practical purposes. The result indicates that the required strength levels derived can be used as a basic information for seismic evaluation and design criteria of low-rise reinforced concrete shear wall buildings having pilotis structure.

The problem of excessive job burdens and high turnover rates in the social welfare area has been dealt with for a long time. However, there is a lack of discussions on the issue of voluntary turnover of medical social workers. The purpose of this study is to examine the effect of job demands on medical social workers' turnover intentions and to verify the mediating effect of job satisfaction on the relationship between job demands and turnover intentions. Among the medical social workers registered in the Korean Association of Medical Social Workers, 188 respondents currently working in hospitals were used for data analysis. As research methods, frequency, descriptive statistics, correlate analysis, and logistic regression analysis were conducted by SPSS 22.0 version and SPSS Macro Process v.2.16. Finally, bootstrap was conducted to verify the significant mediating effect of job satisfaction. The findings are follows: extrinsic job satisfaction was found to have the full mediating effect between job demands and turnover intentions of medical social workers. In other words, job demands of medical social workers affect turnover intentions through extrinsic job satisfaction, but there is no direct effect of the job demand on the turnover intention. On the other hand, intrinsic job satisfaction did not mediate the relationship between job demands and turnover intentions. Based on the results, we suggested organizational and institutional implications for improving the job demands affected to low job satisfaction and turnover intention of medical social workers.
