Objectives: The purpose of this study is to analyze the perception that women in 20s and 30s have on Traditional Korean Medical(TKM) treatment on the leukorrhea. Methods: We studied the perception of TKM treatment by questionnaire From October 1 to November 20, 2010. A questionnaire was given to 50 women and we studied 47 except 3 questionnaire which have inappropriate answer. Results: 1. In 47 women, 46(97.9%) women have heard about leukorrhea, 1(2.1%) woman hasn't heard about it. 2. In 32 women who suffered from the leukorrhea, 14(43.8%) women checked up for leukorrhea. 18(56.2%) women doesn't checked. 10 of 14 women took the medical treatment (drug or injection) and 2 of 14 women took the TKM treatment. 3. In 32 women, 16(50.0%) women know about TKM treatment for leukorrhea, 16(50.0%) women don't know. 4. In 32 women, 20(62.5%) women have intention of TKM treatment for leukorrhea, 2(6.2%) women don't have, and 10(31.3%) women don't know. The biggest obstacle was the high cost of TKM treatment. Conclusions: Many women are willing to take TKM treatment on the leukorrhea. We need more accumulation of data for demonstrating the efficacy and safety of TKM treatment.

This study was conducted in order to survey in healthcare worker's recognition of diagnosis related group(below; DRG) effect from July 1, 2012, to examine their recognition, expectation of the DRG system, and to provide the basic data necessary for the enforcement of the settlement. The subjects of this study were workers at clinics and hospitals sampled from hospital with DRG applying 7 diseases in Busan and Kyung-nam. A questionnaire of survey was conducted with the subjects working at clinics and hospitals from July, 25, 2012 to September 7, 2012, and the subjects were limited to doctors, officers, nurses, medical technicians and nurse assistants, and a total of 618 subjects were enrolled in this study. In the result of this study, generally, the healthcare workers recognized the DRG system. But their knowledge about that was not clear. Expanding enforcement DRG system at the present time, to provide accurate information to the healthcare consumer, workers need to know about DRG system clearly. To this end, for national health policy and medical institutions, workers should be educated constantly about providing medical service as well as the duty of enough explanation about the healthcare consumer's right to know.

A simple linear model to test the hypothesis based on one-on-one relationship has been used to find the causative factors of diseases. However, we now know that not just one, but many factors from different systems such as chemical exposure, genes, epigenetic changes, and proteins are involved in the pathogenesis of chronic diseases such as diabetes mellitus. So, with availability of modern technologies to understand the intricate nature of relations among complex systems, we need to move forward to the future by taking complex systems model.

Companies had to be more intelligent in order to survive in the rapidly changing environments. We need to make a decision to build the Information System to support their decision making. But, how can we know the new system would be better than the old system in making us intelligent? The answer is we can do it with the concept of Intelligence Density. In this study, Intelligence Density concept will be introduced, and the way how it can be applied to the information system will be presented. I think Intelligence Density should be studiedmoretohelpmanagersmakerightdecisions.

Scaffolding works are demolished after this structure is completed, and safety accidents often occur because they are installed differently from legal standards or frequently change during work. Therefore, in order to strengthen the safety of scaffolding, the Ministry of Land, Infrastructure and Transport required a need for design standards for temporary facilities that can systematically prevent and solve large-scale safety accidents that are repeatedly increasing during temporary construction. It has been enacted, and some contents have been revised for the past three years. However, construction site personnel do not know or know the revised matters, but often install scaffolding by the installer's experience rather than complying with relevant laws and regulations. It is the situation that the ground strength test of the foundation ground for the load applied to the floor of the column is omitted in most sites. Therefore, this study grasped the actual situation on the degree of recognition of the revised laws and regulations of the construction site and the foundation-based treatment of the floor working load of the scaffolding column, and derived problems. In addition, we intend to provide reference materials for the endurance test according to the ground conditions to small-scale small sites where it is difficult to conduct the test by carrying out the endurance test of the scaffolding ground according to the revised standards.

Purpose: Simple part or equipment is necessary TRA(Technology Readiness Assessment) or MRA(Manufacturing Readiness Assessment). But sole maturity like TRA, MRA has limit complex systems or SoS(System of System). Especially complex weapon system need from the System Maturity Point of view. This research shows necessity of SRA(System Readiness Assessment). Methods: In case of complex systems, it is essential to SRA(System Readiness Assessment). For the purpose of calculating SRL(System Readiness Level), TRL and IRL must be calculated. And then SRL can obtain know from equation of TRL and IRL. To prove SRA effectiveness, it is calculated SRL of JTDLS(Joint Tactical DataLink System) programs. Results: SRA procedure is proposed and case study shows as examples of JTDLS programs. Although result of TRA is TRL6, result of SRA is not 0.6. From this research, we can know necessity of SRA. Especially complex systems or SoS(System of System) is essential to SRA. Conclusion: SRA(System Readiness Assessment) is required to overcome limitation of sole maturity and to achieve a successful acquisition of high quality weapon system. This research intended to suggest SRA procedure and case study in complex defense system.

Purpose - The main purpose of this study is thus to investigate the contingent effect of imitation strategies on firm performance in transition economies such as China, focusing on pure and creative imitation. Design/methodology - We conducted a survey targeting department heads of each company who have more than 10 years work experiences. We assessed that the ability to gain trust and to access information from high-ranking informants would be greater if the firms were from the same country - Korea - as the lead researcher. A total of 200 highly reliable samples were obtained, which could effectively explain the nine variables set in the study. Relevant hypotheses were tested using a hierarchical linear model (HLM). Findings - The findings suggest that SMEs' technology level also had a positive impact on performance. Firms with better technology had a positive impact on performance, irrespective of pure or creative imitation. This reflects the cases where many Korean SMEs entering China without high technology level lose their competitiveness due to Chinese firms' technology catch-up within a short period of time. Originality/value - SMEs that lack technology and know-how need to focus on pure imitation strategies. It is possible that SMEs can perform creative imitation, but it seems difficult under the current circumstances. Therefore, SMEs with limitations in technology and know-how should maintain their competitive advantage for a while, by maintaining their pure imitation strategy.

Purpose: Since most simulation programs take the interface that lists up all the input variables representing all the functionalities, users must know where design variables of an Energy Conservation Measure (ECM) are located and also know what values are appropriate. This is why practitioner designers feel frustrated when they attempt to use simulation. The final objective of this study is to provide a building energy modeling guideline for practitioners in various fields such as architectural design and MEP. Method: As the first step of the modeling guideline, this study provides the Level of Detail (LOD) for simulation modeling of primary ECMs considering the design information available in each design phase. It is prepared by literature review, simulation functionality investigation, and field experts' survey. Result: The proposed simulation LOD offers a milestone at each design phases concerning what design variable and attributes need to be developed with how much of details in order to meet the project goal. Also each design team can set up a simulation usecase considering organizational characteristics based on the proposed LOD.

During manufacturing thick composite cylinders, large thermal residual stresses are developed and induce catastrophic interlaminar failures. Since the residual stresses are dependent on many process parameters, such as temperature distribution during cure, cure shrinkage, winding tension, and migration of fibers, calculation of the residual stresses is very difficult. Therefore a radial-cut method have been used to measure the residual stresses in the composite cylinders. But the conventional radial-cut method needs to know numerous material properties which are not only troublesome to obtain but also vary with change of fiber arrangement during consolidation. In this paper, a new radial-cut method with cut-cylinder-bending test was proposed and the measured residual stresses were compared with calculated thermal residual stresses. It was found that the new radial-cut method which does not need to know any of material properties gave better estimation of residual stresses regardless of radial variation of material properties. Additionally, interlaminar tensile strength could be obtained by the cut-cylinder-bending test.

Integral imaging attracts much attention as an autostereoscopic three-dimensional (3D) display technique for its many advantages. Recently the method that uses a curved lens array with a curved screen has been reported to overcome the limitation of viewing angle in integral imaging. This method widens the viewing angle remarkably. However, to understand the proposed system we need to know how the depth is limited in the proposed method also. We analyze the depth limitation and show the simulation results.
