The purpose of this study is to prove an importance of systemic analysis paradigm to interpret fashion make-up. This research employed 'paradigm for interpretation of fashion make-up signs' theory to analyze data. This theory consists of three steps to interpret the meaning of a work: (1) recognition of form, (2) analysis of connotation meanings, and (3) analysis of symbolic meanings and communication. The results of this study were as follows. Jean Paul Gaultier's eye make-up uses a square pattern that mostly consists of the color black. He presents a Glam Rock image by using rimmed make-up that portrays an avant-garde and a nonmainstream culture. Jean Paul Gaultier's make-up was showing black color and square eye pattern and was presenting Glam Rock image and was a rimmed make-up meaning a nonmainstream culture and Avant-garde symbolically. Chanel's make-up emphasizes the eyehole with the rimmed technique by applying the make-up of Marchesa Casati and including non-popularity, Limited Marketing symbolically. Christian Dior's make-up applies the representative make-up of Joan of Arc and Siouxsie sioux and also uses rimmed make-up to portray the meaning of religion persecution, the dark-ages militarism and including Humanism symbolically.

Failure patterns of rock specimens represent valuable information about the mechanical properties and crack evolution mechanism of rock. Several kinds of research have been conducted regarding the failure mechanism of brittle material, however; the influence of brittleness on the failure mechanism of rock specimens has not been precisely considered. In the present study, experimental and numerical examinations have been made to evaluate the physical and mechanical phenomena associated with rock failure mechanisms through the uniaxial compression test. In the experimental part, Unconfined Compressive Strength (UCS) tests equipped with Acoustic Emission (AE) have been conducted on rock samples with three different brittleness. Then, the numerical models have been calibrated based on experimental test results for further investigation and comparing the micro-cracking process in experimental and numerical models. It can be perceived that the failure mode of specimens with high brittleness is tensile axial splitting, based on the experimental evidence of rock specimens with different brittleness. Also, the crack growth mechanism of the rock specimens with various brittleness using discrete element modeling in the numerical part suggested that the specimens with more brittleness contain more tensile fracture during the loading sequences.

A detailed experimental program was conducted to investigate the flexural behavior of ultra high performance concrete (UHPC) beams reinforced with high strength steel (HSS) rebars with a specified yield strength of 600 MPa via direct tensile test and monotonic four-point bending test. First, two sets of direct tensile test specimens, with the same reinforcement ratio but different yield strength of reinforcement, were fabricated and tested. Subsequently, six simply supported beams, including two plain UHPC beams and four reinforced UHPC beams, were prepared and tested under four-point bending load. The results showed that the balanced-reinforced UHPC beams reinforced with HSS rebars could improve the ultimate load-bearing capacity, deformation capacity, ductility properties, etc. more effectively owing to interaction between high strength of HSS rebar and strain-hardening characteristic of UHPC. In addition, the UHPC with steel rebars kept strain compatibility prior to the yielding of the steel rebar, further satisfied the plane-section assumption. Most importantly, the crack pattern of the UHPC beam reinforced with HSS rebars was prone to transform from single main crack failure corresponding to the normal-strength steel, to multiple main cracks failure under the condition of balanced-reinforced failure, which validated by the conclusion of direct tensile tests cooperated with acoustic emission (AE) source locating technique as well.

This study aimed to reconfirm the sex change scale and pattern of Tegillarca granosa. Although the sex ratio (female : male, female proportion) of T. granosa was 1:2.32 (30.2%) at the initial stage (2011) of the study, it was 1:0.94 (51.5%) after one year (2012) in the same population. The increase of the female proportion was greater in the 2+ year class (23.0%) when compared to the 1+ year class (19.2%). Overall, sex change ratio of 37.6% was observed in this population of T. granosa. The sex change ratio of the 2+ year class (39.3%) was higher than that of the 1+ year class (35.3%). And sex change ratio in the males (42.2%) was higher than that in the females (26.9%). The female proportion was the opposite of the result from 2006~2007, and one of the causes was presumed to be the difference in cumulative water temperature during the gonadal inactive stage (winter).

As the Mekong River basin is a nationally shared river, it is difficult to collect precipitation data, and the quantitative and qualitative quality of the data sets differs from country to country, which may increase the uncertainty of hydrological analysis results. Recently, with the development of remote sensing technology, it has become easier to obtain grid-based precipitation products(GPPs), and various hydrological analysis studies have been conducted in unmeasured or large watersheds using GPPs. In this study, rainfall-runoff simulation in the Mekong River basin was conducted using the SWAT model, which is a quasi-distribution model with three satellite GPPs (TRMM, GSMaP, PERSIANN-CDR) and two GPPs (APHRODITE, GPCC). Four water level stations, Luang Prabang, Pakse, Stung Treng, and Kratie, which are major outlets of the main Mekong River, were selected, and the parameters of the SWAT model were calibrated using APHRODITE as an observation value for the period from 2001 to 2011 and runoff simulations were verified for the period form 2012 to 2013. In addition, using the ConvAE, a convolutional neural network model, spatio-temporal correction of original satellite precipitation products was performed, and rainfall-runoff performances were compared before and after correction of satellite precipitation products. The original satellite precipitation products and GPCC showed a quantitatively under- or over-estimated or spatially very different pattern compared to APHPRODITE, whereas, in the case of satellite precipitation prodcuts corrected using ConvAE, spatial correlation was dramatically improved. In the case of runoff simulation, the runoff simulation results using the satellite precipitation products corrected by ConvAE for all the outlets have significantly improved accuracy than the runoff results using original satellite precipitation products. Therefore, the bias correction technique using the ConvAE technique presented in this study can be applied in various hydrological analysis for large watersheds where rain guage network is not dense.

We identified the intake pattern and consumption propensity of milk and sought improvements to promote consumption of milk. We targeted 362 preschool children aged 5~7 years old who attended nursery school in the Bucheon area. Questionnaires were distributed and 328 questionnaires were collected. Approximately 36.2% of boys and 31.2% of gorls drank milk six times per week. A total of 32.9% of the preschool children drank more than 2 cups of milk/day. Approximately 72.9% of them currently drink white milk, and 46.0% preferred milk to processed milk. The reasons why they drink milk included 'want to be tall'(66.5%) and 'good health'(52.4%). Mothers(54.6%)and preschool children(39.3%) were the purchasers with the greatest impact on product purchases. Consumer propensity to buy milk was shown in the order of expiration date(4.80 points), and nutrition facts(4.01 points). (4.88 points) and enhanced nutrients(4.59 points) should be promoted for milk consumption. Therefore, it is thought that continuous nutrition education should be made together in order to increase consumption of milk of children and education targeting teachers and school parents should be conducted as well. And in order for children to drink milk without repulsion, the development of various products satisfying both symbolic aspects and nutritional aspects should continue to be made.

This study was carried out to establish most suitable freezing condition, to evaluate the different glycerol concentration of freezing and thawing rates on motility, viability, membrane integrity and acrosome intecrity of frozen Korean Jeju Black Bull spermatozoa, Semen was collected from a Korean Jeju Black Bull using an artificial vagina and transported to the laboratory. The semen was extended gradually 1:5 then cooled slowly for 2 hrs to 4$^{\circ}C$. The semen was diluted 1:1 with cryoprotectant extenders (3%, 5% and 7% glycerol) and equilibrated for 2 hrs at cold chamber and packed to 0.5 ml straws. The semen straws were located above 3 cm of liquid nitrogen for 5 minutes, above 5 cm for 10 min and above 8 cm for 10 min. And then the frozen straw was plunged into LN$_2$. The presented straws were examined the viability and motility after thawed at 37$^{\circ}C$ water bath. The viability and membrane integrity immediately post-thawing were significantly higher in samples frozen in 7% glycerol than 3% and 5% glycerol (p<0.05). After CTC staining to assess acrosome integrity, F pattern was significantly increased, but B pattern was significantly decreased in 7% glycerol (p<0.05). Freezing distance of 5 cm from liquid nitrogen and pre-cooling for 10 min yield better survival and membrane integrity, but not significant difference. However, AR pattern according to CTC staining was significantly decreased in 3 cm for 5 min.

The study intends to seek the creative ideas that can satisfy the needs of individual consumers by rediscovering the modern meaning and the artistic value of geometric ornaments engraved on the backside of Danyugyung, which is a traditional Korean pattern. In terms of the study method, the symbolic meaning and formative characteristics of Danyugyung were determined, and the form of its pattern and the geometric characteristics were analyzed. Based on this, Photoshop and illustrations were used to apply the shapes of Danyugyung and internal patterns to the textile designs, and the results are as follows. Firstly, it was found that Danyugyung was associated with the bronze mirror, which was used from the Bronze Age to the Early Iron Age, and was the product of artistic activities and an object and acted as a shamanistic and authoritative symbol of the ruling parties, which were responsible for the acts related to the spiritual world. Secondly, it was discovered that forms of Danyugyung were classified into Jomungyung and Semungyung in accordance with Forms of Danyugyung (造飾), and the formative features of the geometric ornaments that were engraved in great detail on the backside could be found in the images which change according to the form of the inner patterns. Thirdly, with regard to the development of the textile designs utilizing the shape and inner patterns of Danyugyung based on the formative features, it was could discover that the simple shape of Danyugyung presented a value which can be applied as a unique design factor delivering a visual rhythm by attempting to create various harmonies overlapping lines engraved on the inner patterns and the shapes of Danyugyung. Based on the above-mentioned outcomes, the possibility was confirmed that Danyugyung can be used as a novel motif and as a standard unit of patterns for textile design. With future studies, I would like to utilize the unique and diverse images as pattern motif for textile design.

The genus Sedum comprises about 400 taxa with worldwide distribution, and about 20 taxa of the genus Phedimus distributed from Asia to Europe. According to some taxonomists, Phedimus and Sedum are two separate genera of the family Crassulaceae; however, in Korea Phedimus has been treated as a subgenus Aizoon within the genus Sedum. This ambiguous taxonomic treatment of the genus Phedimus needs further confirmation. In the study, we investigated morphological characteristics such as the whole plant height, leaf morphology, and seed coat features of these two genera. We believe that these characters are very important to distinguish Phedimus and Sedum. The result indicated that the seed surface pattern was the most useful diagnostic character. The Sedum had a hexagonal pattern with a single nipple protrusion, whereas the Phedimus had a rectangular pattern with papilla on both ends. The results of this study strongly support the separation of Phedimus from Sedum and thus Phedimus need to be treated as an independent genus.

The hydro-dynamical and ecological coupled model were applied in the Tokyo Bay, to evaluate the flow pattern including water quality parameters and the distribution of biomass flux, and to compare with the results obtained from the satellite data during March 2001. The flow pattern and salinity distribution obtained from the present model were nearly identical with those of the previous studies. SST from NOAA/AVHRR was $2.5^{\circ}C$ higher than model results in the mouth of bay and $0.5^{\circ}C$ lower than model results in the inner bay, respectively. It was found that the concentration of chlorophyll-a estimated from SeaWiFS was considerably higher than that of model result, regardless similar distribution pattern. This disagreement will be studied through the more elaborate investigation in the future.
