This study analyzed the maltol quality, composition ratio of fatty acids, and contents of phenolic compounds in white ginseng extracts(four types), red ginseng extracts(five types), black ginseng extracts(two types), and Chinese ginseng extracts(nine types). By examining patterns in these measurements, we determined the characteristic factors of the extracts and measured the possibility of qualitative analysis. In the analysis of maltol using TLC, white ginseng extracts were not detected while red and black ginseng extracts were detected, so the possibility of detection was considered as a characteristic factor for qualitative analysis. Regarding the composition of fatty acids, palmitic and linoleic acids were the main fatty acids in the ginseng extracts palmitic acid was high in white ginseng extracts while linoleic was low in red ginseng extracts. Regarding the ratio(Pal/Lin) of the two fatty acids, there was a large difference between white ginseng extracts(56.7~64.3%) and red ginseng extracts(32.0~38.5%), and these figures seemed to be characteristic factors for the analysis. For the phenolic compounds, extracts contained maltol, caffeic acid, syringic acid, p-coumaric acid, ferulic acid, and cinnamic acid. White ginseng extracts contained similar percentages of phenolic compounds while red ginseng extracts had high maltol content. According to the measurement results of the percentages of maltol and cinnamic acid, white ginseng extracts showed values below five, whereas red and black ginseng extracts showed 53~289, which was also a characteristic factor for qualitative analysis. Consequently, we found that we can differentiate between ginseng extracts using characteristic factors that we analyzed in an experiment on white ginseng extracts from China.

As many stakeholders are taking part in the Housing Redevelopment Project, their opinion mediation is considering very important issues. Thus disputes on projects are inevitable due to complexity of interest. To effectively progress the project, this paper analyze the risk factors by phase in implementation phase that the association participates in person. We identify 50 of risk factors in implementation phase by reviewing and analyzing related studies and actual cases of disputes, then we present 26 of risk factors through experts interview. Also, we calculate weights of risk factors by using AHP for quantitatively analyzing them and present final weights and priorities of risk factors by summing weights of risk factors by phase. In results, it is found that 'the inappropriateness of the Management Disposal Plan' in management disposal plan phase and 'the inappropriateness of the Project Implementation Plan' are the most significant risk factors. To maximize the utilization of risk factors analyzed, we present the checklists that can be aware of these risks in advance and prevent these risks. Based on these findings, if risk factors in implementation phase are managed actively, the housing redevelopment project will be performed more effectively.

Diagnosis and treatment of the unstable shoulder is one of the more difficult problems in orthopaedic surgery. There is confusion between the normal laxity with translation and subluxation of the humeral head relative to the glenoid and an abnormal amount of laxity, leading to pain and dysfunction. Unfortunately, there is no single treatment that applied to all lesions that cause the instability. It is imperative, therefore, that an accurate diagnosis be made, including the directions and degree of shoulder instability as well as any coexisting problems. Anatomical defects must be defined. Common factors that could most readily compromised instability repair are examined. These include techniques for making an accurate diagnosis with identification of the precise anatomical pathology, and the rationale for appropriate surgical treatment with the avoidance of technical complication such as unnecessary hardware or exposures that might lead to residual instability, arthritis, and nerve or vascular injuries. Additional injuries may be prevented by careful rehabilitation postoperatively to restore shoulder stability, flexibility, and endurance prior to an individual's return to stressful sports or work.

본 연구에서는 기업의 기술혁신활동 결정요인을 과학기술정책연구원이 발표한 KIS(Korean Innovation Survey) 2002를 활용하여 분석하였다. 특히 혁신활동에 있어서 기업규모와 네트워크의 역할에 초점을 맞추었다. 기술혁신활동을 제품혁신, 제품개선, 그리고 공정혁신으로 구분하였으며, 기술혁신활동의 결정요인으로 이윤율, 수출비율, 해외지분, 기업연령, 시장집중도, R&D활동 착수여부, 그리고 산업별 R&D집약도 등이 추가로 고려되었다. 분석된 표본은 제조업에 속한 1,124개 기업으로 정성적 분석방법인 로지스틱 회귀모형(logistic regression)을 사용하였다. 분석결과, 첫째 기업의 기술혁신활동 결정요인은 혁신유형에 따라서 다르게 분석되었다. 예를 들어, 기업규모와 기술혁신활동에 관한 슘페터 가설은 제품혁신에서는 성립하지 않는 것으로 나타났으나. 제품개선 및 공정혁신에 대해서는 성립하는 것으로 분석되었다. 둘째, 예측한 대로 소기업과 대기업간 기술혁신활동의 결정요인에 있어서 많은 차이점이 발견되었고, 이러한 차이는 제품혁신과 공정혁신에서 현격하게 나타났다. 셋째, 기업규모 및 혁신유형에 관계없이 외부적 네트워크는 기술혁신활동에 대해 정(正)(+)의 유의한 효과를 나타내어, 혁신활동에서 협력의 중요성을 확인해 주었다. 그러나 협력대상별 네트워크효과는 기업규모와 혁신유형에 따라서 많은 차이점을 보여주었다.

Tunnel sections on the expressway are different from rest of sections on the expressway in terms of velocity, the number of passing cars, and vehicle density which, in particular, affect drivers' behavior before and after drivers pass through the tunnel. However, literature review reveals that former studies are too focused on quantitative indicator to consider qualitative aspects. Thus, this study tried to find out qualitative factors affecting speed reduction in tunnel sections based on questionnaire surveys and its analysis in tunnel sections selected by taking consideration of diverse conditions. Analysis showed that factors concerning tunnel configuration (lane width, shoulder width, and tunnel length) related to very long tunnels increasingly popular recently had some effects on reduced speed inside of tunnels. It appeared that visual environment such as visibility of tunnel entrance had an impact in speed reduction and vehicle speed tended to change according to lighting illumination level inside of tunnels. It is expected that continual investment would be made in technological development related to expressway tunnel design and service improvement based on this study.

Interactive space became one of the major design paradigms. For elevating the interactive effect in this, we need user-centered design methodology which uses the influential factors on the interactivity. As the second paper of three-linked studies for the interactivity in the interactive space, this research analyzed the interface factors' specific attributes for supporting behavioral participation. 'Interface' is one of three main factors on the interactivity(Intersubject/Interface/Interaction). Its role in the interactive space is to induce or support user's participations which bring the interactive changes into the designs. Qualitative case analysis was the main method and 30 cases were investigated. 'Individual analysis-Transitional description-Generalization' were the progressive steps for case analysis. As final results, 17 attributes for supporting behavioral participation were analyzed.

This study examines the psychological factors of consumers to On-Demand O2O service which is different from the previous study on O2O service. To investigate the relative influence of consumer's psychological attachment of On-Demand O2O service, enjoyment, and trust on consumer's satisfaction and attitude, I conducted qualitative and quantitative surveys to investigate consumers' perception. Through the quantitative survey on 152 participants, the study shows that the consumer's psychological attachment to the service has the greatest influence on the attitude toward On-Demand O2O service and the trust has the highest effect on satisfaction with service. This study is meaningful in that the consumer's psychological factors to the O2O service is examined from the consumer's point of view. This study suggests that the consumer's attachment and trust should be considered primarily to expand the On-Demand O2O service.

자연계의 모든 것은 어떠한 형태로든 변동을 가진다. 이러한 변동을 해석하고 이 변동의 경향을 분석하면 이후의 변동을 예측할 수 있게된다. 그러므로 변동의 분석은 변동의 예측과 나아가 변동의 제어를 가능하게 하는 바탕이 된다. 방적사는 그것의 원료가 되는 섬유의 특성과 제조 공정중의 많은 변동요인 즉, 기계의 결함, 공정 자체의 요소들에 의하여 불균제를 일으키는 변동을 가지게 된다. (중략)
