This objectives of this research was to look into the actual state of fashion wearing purchase and makeup purchase to recognize the interrelationship between fashion and makeup styles by selecting words used for fashion image and cosmetic style. Such study can offer basic materials for choice of makeup style by each fashion style. Most information on fashion and cosmetics were obtained through the internet. However, a lot of information on cosmetics were also obtained through TV. Therefore, if fashion companies use both internet and TV for advertising, more effect on purchasing might be obtained. The design and color are important standards for selecting clothes. However, the quality and price of clothes are essential standards for purchasing cosmetics. Therefore, for fashion companies, they need to pay more attention to design and color. However, for cosmetic companies, they need to take notice of quality and price. When image words were extracted, fashion images showed the following words: natural, romantic, elegance, casual, and avant-garde, while makeup images showed romantic-casual, elegance, avant-garde, and natural. Regarding the interrelationship between fashion style and makeup style, natural and casual fashion style were harmonized with natural makeup while romantic fashion style was associated with romantic makeup. The fashion style of elegance and avant- garde was associated with elegance makeup. Therefore, similar images were found between fashion and makeup styles.

The purpose of this study is to examine the accuracy of the code provisions on lateral load distribution factors of prestressed concrete girder bridges. Most designers in Korea use the lever method or lateral load distribution formula in the existing design codes. However, the methods do not account for the effect of bridge skew or direction of diaphragm. Therefore, this study analysed the prestressed concrete girder bridge with grillage model for various girder spacings, directions of diaphragms, span lengths, and skews, and compared the results with those of existing design code. It has been found that lateral load distribution factors were proportional to the girder spacing while they were not significantly affected by the change of span length, direction of diaphragm, and skew. For bending moments, lateral load distribution factors from the grillage analysis were 60%~68% of those from Korean bridge design code. Therefore, the code provisions result in very conservative design. For support reactions, however, lateral load distribution factors from the grillage analysis were slightly greater than those from Korean bridge design code. Therefore, the capacity of bearings of the bridge with a large skew should be determined by grillage analysis.

Application of Hidden Markov Model (HMM) to the hydrological time series would be an innovative way to identify extreme rainfall events in a series. Even though the optimum number of hidden states can be identify based on maximizing the log-likelihood or minimizing Bayesian information criterion. However, occasionally value for the log-likelihood keep increasing with the state which gives false identification of the optimum hidden state. Therefore, this study attempts to identify optimum number of hidden states for Colombo station, Sri Lanka as fundamental approach to identify frequency and percentage of extreme rainfall events for the station. Colombo station consisted of daily rainfall values between 1961 and 2015. The representative station is located at the wet zone of Sri Lanka where the major rainfall season falls on May to September. Therefore, HMM was ran for the season of May to September between 1961 and 2015. Results showed more or less similar log-likelihood which could be identified as maximum for states between 4 to 7. Therefore, measure of central tendency (i.e. mean, median, mode, standard deviation, variance and auto-correlation) for observed and simulated daily rainfall series was carried to each state to identify optimum state which could give statistically compatible results. Further, the method was applied for the second major rainfall season (i.e. October to February) for the same station as a comparison.

Mechanical property of tissue is closely related to diseases such as breast cancer, prostate cancer, cirrhosis of the liver, and atherosclerosis. Therefore measurement of tissue mechanical property is important for a better diagnosis. Ultrasound elastography has been developed as a diagnostic modality for a number of diseases that maps mechanical property of tissue. Optical coherence elastography (OCE) has a higher spatial resolution than ultrasound elastography. OCE, therefore, could be a great help for early diagnosis. In this study, we made tissue phantoms and measured their compressive moduli with a rheometer measuring the response to applied force. Uniaxial strain of the tissue phantom was also measured with OCE by using cross-correlation of speckles and compared with the results from the rheometer. In order to compare stiffness of tissue phantoms by OCE, the applied force should be measured in addition to the strain. We, however, did not use a load cell that directly measures the applied force for each sample. Instead, we utilized one silicone film (called as reference phantom) for all OCE measurements that indirectly indicated the amount of the applied force by deformation. Therefore, all measurements were based on displacement, which was natural and effective for image-based elastography such as OCE.

Cylinder liners used in diesel engines of combat equipment are prone to cavitation due to wet cooling. The damage caused by erosion and corrosion due to cavitation has a fatal effect on the performance and lifespan of a diesel engine. Therefore, a study was conducted to improve the durability of cylinder liners. Two surface treatment techniques were proposed: nitriding and chrome plating. It was observed that the amount of erosion on the surface of nitride-treated cylinder liners was high because the surface-treated part eroded due to its weak impact resistance against the bubble explosion generated by cavitation. In contrast, the chrome-plated cylinder liner had a lower amount of erosion among the specimens subjected to the accelerated test. These results verified that the resistance of chrome-plated liners against cavitation is high. Therefore, it can withstand the impact of bubble explosion. If the chrome plating thickness is set with reference to the KS standard, an exceptional durability of abrasion, wear resistance, and corrosion resistance can be obtained. If the thickness is set between 120~250㎛, it is expected that the durability of the cylinder liner can be improved. Although a recovery method for corroded cylinder liners is suggested, the proposed method has an inherent risk of crack generation. Therefore, further research is required to solve this problem.

Lifestyle of Health and Sustainability (LOHAS) influences the development of hygienic and health-oriented functional textile products; consequently, there has been an increase in the prospects for environmentally friendly natural dyeing products with functional and sensitive characteristics. Therefore, the present study expresses a functional manifestation on fabrics by treatment with chitosan and tannin using natural Coptidis Rhizoma. Cotton and wool fabrics dyed with Coptidis Rhizoma after treatment with chitosan and tannin. Consequently, the antibiosis of fabric dyed with Coptidis Rhizoma was excellent with 99.9% bacterial reduction for Staphylococcus aureus and Klebsiella pneumoniae in both fabrics. The deodorization rate was more than 90.0% in both fabrics after 120 minutes. The UV-A protection rate was 88.2% and the UV-B protection rate was 87.7% for cotton. The UV-A protection rate was 88.2% and the UV-B protection rate was 84.3% for wool fabric. Therefore, both of the dyed fabrics showed excellent UV protection by treatment with only chitosan and tannin, without mordants. Therefore, chitosan and tannin treatments were able to manifest functionalities in the fabrics dyed with Coptidis Rhizoma.

Recently, residents' community center is trying to combine with various program and facilities as the residents self-government program's development. This is due to the reduction of administrative tasks, the computerization of programs, the importance of community participation activities, the activation of community, and the increase of welfare projects. Therefore, previous studies on program complexity have been actively carried out. Nevertheless, spaces and programs studies of considering regional characteristics are lacking. Therefore, the community centers' program and spaces need to change. Therefore, this study propose an improvement direction through analyzing the situation of the residents' community center. For this study, the precedent research and institutional limitations are examined. In addition, this study selected and analyzed the 15 local community center. Thirdly, interviews were conducted with users and officials of the 5 residents' community centers on major changes. Finally, This study suggests direction of program improvement and architectural design direction. As a result of this study, integrated management measures with overlapping agencies should be sought. Surplus space will have to be rearranged into a new program through prior examination. Above all, the proposed remodeling guidelines require user requirements to be reflected and designed with the residents.

The safety inspection cost of the construction work was based on commercial facilities classified as a single building. Therefore, it is not possible to fully reflect the characteristics of the multi-building construction project such as apartment houses. Therefore, this study suggests a reasonable estimation model that can fully reflect the characteristics of the multi-building construction project. The safety inspection cost estimation model proposed two models such as construction cost ratio method and cost plus fixed fee method. And these models were simulated by the apartment construction work and compared with the current standard. As a result, the current construction cost ratio method has shown that the safety inspection cost tends to be overestimated as the construction size increases. Therefore, the proposed model has reflected characteristics of the multi-building construction project, so that it can reasonably estimate the safety inspection cost more than the current standard.
