The purpose of this study was to analyse craniofacial shape by 3D scanner for female adults with age groups. In this study, heads of 452 female adults were measured by 3D scanner. The obtained 25 measurements were analyzed by statistical methods. The results can be summarized as follows; 1. From the basic statistical data analysis, vertex-tragion and the length between the pupils were the longest in their twenties, and grew shorter in elderly groups. The length of nasion-subnasale and the width of mouth increased with an increased in age. 2. According to the analysis of the craniofacial proportions, the head type of female aduls was short-headed. The size of lower face increased with an increase in age. 3. The statistically noticeable differences were found in the measurement of the left and the right sides of face in the age groups of 20, 30, and 40. 4. High correlations were found in two perpendicular lengths, two horizontal lengths and two widths. 5. The order of factor analysis was as follows; the horizontal length, the perpendicular length and the width from highest.
For the structural integrity evaluation of pressurized water reactor (PWR) steam generator (SG) tubes subjected to transient hydraulic loading, determination of the tube-to-tube gap velocity and static pressure distributions along the tubes is prerequisite. This paper addresses both computational fluid dynamics (CFD) and analytical approaches for predicting the tube-to-tube gap velocity and static pressure distributions during blowdown following a feedwater line break (FWLB) accident at a PWR SG. First of all, a comparative study on CFD calculations of the transient velocity and pressure distributions in the SG secondary sides for two different models having 30 or no tubes is performed. The result shows that the velocities of sub-cooled water flowing between any adjacent two tubes of a tubed SG model during blowdown can be roughly estimated by applying the specified SG secondary side porosity to those of the no-tubed SG model. Secondly, simplified analytical approximate solutions for the steady two-dimensional SG secondary flow velocity and pressure distributions under a given discharge flowrate are derived using a line sink model. The simplified analytical solutions are validated by comparing them to the CFD calculations.
Objective: To compare three-dimensionally the midfacial hard- and soft-tissue asymmetries between the affected and the unaffected sides and determine the relationship between the hard tissue and the overlying soft tissue in patients with nonsyndromic complete unilateral cleft lip and palate (UCLP) by cone-beam computed tomography (CBCT) analysis. Methods: The maxillofacial regions of 26 adults (18 men, 8 women) with nonsyndromic UCLP were scanned by CBCT and reconstructed by three-dimensional dental imaging. The frontal-view midfacial analysis was based on a $3{\times}3$ grid of vertical and horizontal lines and their intersecting points. Two additional points were used for assessing the dentoalveolar area. Linear and surface measurements from three reference planes (Basion-perpendicular, midsagittal reference, and Frankfurt horizontal planes) to the intersecting points were used to evaluate the anteroposterior, transverse, and vertical asymmetries as well as convexity or concavity. Results: Anteroposteriorly, the soft tissue in the nasolabial and dentoalveolar regions was significantly thicker and positioned more anteriorly on the affected side than on the unaffected side (p < 0.05). The hard tissue in the dentoalveolar region was significantly retruded on the affected side compared with the unaffected side (p < 0.05). The other midfacial regions showed no significant differences. Conclusions: With the exception of the nasolabial and dentoalveolar regions, no distinctive midfacial hard- and soft-tissue asymmetries exist between the affected and the unaffected sides in patients with nonsyndromic UCLP.

The purpose of this thesis is to show the historical context of tongue-viscera correspondence scheme based on as wide investigation as possible. For this purpose, we collected and investigated 35 books related to tongue diagnosis. As a result, we faound the following: There were some tentative trials to associate viscera or viscera meridians with tongue areas since shown in the Effective formulae of inherited medical works (世醫得效方, 1337). The main stream of tongue-viscera correspondence scheme was the form in which the apex, the center, and the root of tongue are associated with Heart, Spleen (and Stomach), and Kidney. On the viscera correspondence to the sides of tongue, there had been two streams. The first one is originated from the Upper-most Book on Shanghan (傷寒第一書, 1780), in which the sides of tongue are assumed to be associated with Liver and Gall-bladder. The second one is originated from the Ikeda Family's Chant on the Tongue (池田家舌函口訣, 1807), in which the left side and the right side of tongue are assumed to be associated with Liver and Lung separately. The former type have been accepted as the standard form in modern traditional Asian medicine education. In addition to the above types, three other correspondence schemes were also existed, but have disappeared now. These days, some new correspondence schemes are being suggested based on new approaches.

This study measured consumer's recognition, reliability, emotion and images about current eco-marks as well proposed an eco-mark rating scale and mark designs to improve consumer's trust on the fashion product marks. We used a questionnaire survey to collect data from 150 persons about knowledge, interests, and practice on eco fashion products in relation to trustfulness and positive images for three domestic and three international eco-marks. We evaluated and gave eco scores to six fiber-type products (cotton, organic cotton, wool, polyester, biodegradable polyester and nylon) in terms of consumer's use, water & land consumption, waste amount, carbon footprint, and toxicity. We suggested a new 5-level rating scale for eco marks, which quantified the concept of environmental friendliness of fiber products. The design for eco-mark of rating scale showed the total grade with two sub scores of environmental sides and human sides developed with an improved visual understanding for consumers. The design is one through benchmarking the energy-consumption efficiency mark, which is familiar to consumers such as a half circle shape to save environment resources to alarm consumers to environment problems.
This is a study on the ㄱ-shaped church in Korean Protestant churches. Since the Protestantism had been introduced into Korea, the style of ㄱ-shaped church was the popular style that have been fashioned in all the country of Korea. When the Protestantism was introduced into Korea, ideology which ruled over the Society of Chosun Dynasty was the Confucianism that emphasized the precepts, for example, the loyalty for the King, distinction between the sexes and so on. The Korean Protestants built the church which had ㄱ-shaped plan, so that they solved the second problem : 'distinction between the sexes'. The style of the ㄱ-shaped church is one of the characteristics which distinguish the Korean church from other nations'. Actually the ㄱ-shaped churches had been built by Korean Protestant denominations, from the early days of introducing the Protestantism till the end of 1920's. Even though most of the style of the ㄱ-shaped church is replaced with the modern style according to the extension of religious influence, luckily the ㄱ-shaped two churches : Kumsan Church(1908), Toodong Church(1929) are in existence in the Provice of ChonBuk. The purpose of this study is to make the architectural characteristics of the ㄱ-shaped church clear. This study is based on the actual survey of the ㄱ-shaped churches in existence: Kumsan Church, the Toodong Church and on the documents, photographs, interviews and so on for investigation not existing one now. The ㄱ-shaped church have the plan to separate men's side from women's with a right angle and have a pulpit which was placed at the meeting point of the front part of men's and women's sides. Generally, seen from the court, the churches have men's side in left and women's one in right. There was a screen blocking both sides in the church. But it disappeared in 1920's according to the change of the social conventionality. Most of its structural form is the Korean wooden style. The ㄱ-shaped church appeared in a transition period of the Korean church architecture.

The re-examination of morphological and anatomical characters of Laminaria appressirhiza and L. inclinatorhiza collected from different localities in the Sea of Okhotsk was performed. Despite their commercial and ecological importance to the region they have not been comprehensively reviewed since their first description in 1970. Our results show that some original diagnostic key characters (e.g., shape of holdfast, shape of sporangial sori, and dissection of blade) are not stable and have deviations from the type morphology when plants grow in different environments. In L. inclinatorhiza, the sporangial sori development occurred differently to the pattern indicated in original species description as they did not develop simultaneously on both sides of the blade. Instead, the sporangial sori outlines on both sides of the blade did not coincide at first and only became coincident later. Also, a deep-water population of L. inclinatorhiza with an unusual and interesting morphology, growing at depths of 15-25 m on opened rocky coasts in Taujskaya Bay (northern part of the Sea of Okhotsk) was found. The stable diagnostic key characters to distinguish these two species are the cone-like, multilayered, very thick and massive holdfast (in L. inclinatorhiza) and rolled margins of blades, lamellar rosette-like part of thallus, and sporangial sori developing only on one side of the blade (in L. appressirhiza). The ecological characteristics, distribution, and abundance of both species in the Sea of Okhotsk are discussed. Both species are perennial and widely distributed in the region. L. appressirhiza is more often found as a subdominant species among other kelps, forming maximum biomass and density of 7-9 kg and 8-25 plants per $1m^2$, respectively. L. inclinatorhiza sometimes forms local mono-species communities with maximum biomass and density of 10-12 kg and 10-15 plants per $1m^2$, respectively.

A new mathematical model and its finite element formulation for the non-linear stress-strain analysis of a planar beam strengthened with plates bolted or adhesively bonded to its lateral sides is presented. The connection between the layers is considered to be flexible in both the longitudinal and the transversal direction. The following assumptions are also adopted in the model: for each layer (i.e., the beam and the side plates) the geometrically linear and materially non-linear Bernoulli's beam theory is assumed, all of the layers are made of different homogeneous non-linear materials, the debonding of the beam from the side-plates due to, for example, a local buckling of the side plate, is prevented. The suitability of the theory is verified by the comparison of the present numerical results with experimental and numerical results from literature. The mechanical response arising from the theoretical model and its numerical formulation has been found realistic and the numerical model has been proven to be reliable and computationally effective. Finally, the present formulation is employed in the analysis of the effects of two different realizations of strengthening of a characteristic simply supported flexural beam (plates on the sides of the beam versus the tension-face plates). The analysis reveals that side plates efficiently enhance the bearing capacity of the flexural beam and can, in some cases, outperform the tensile-face plates in a lower loss of ductility, especially, if the connection between the beam and the side plates is sufficiently stiff.

Objective : The subgenual cingulate cortex, a part of default-mode network, has been known to playa key role in the pathophysiology of depression. The previous studies have reported abnormal functional connectivity between the subgenual cingulate cortex and other brain regions in the patients with depression. The goal of this shldy was to explore the resting-state functional connectivity of the subgenual cingulate cortex between the patients with depression and healthy subjects. Methods : Twenty patients with major depression and age- and sex-matched 20 healthy subjects underwent 5-minute resting state fMRI scans. The functional connectivity map in each subject was acquired using seed-based correlation analysis with the seed located in the subgenual cingulate cortex (Talairach coordinates; x=-10, y=5, z=-10). The functional connectivity maps were calculated using AFNI and compared between the patient and healthy subject group via two-sample T-test using 3dttest++ in AFNI package. Results : Functional connectivity was decreased between the subgenual cingulate cortex and both sides of fusiform gyrus in depressed subjects. Connectivity was also decreased between the subgenual cingulate cortex and the left cerebellum in the patient group. There was no correlation between the severity of depression and the degree of functional connectivity between the subgenual cingulate cortex and the regions showing decreased functional connectivity. Conclusion : Decreased resting-state functional connectivity between the subgenual cingulate cortex and both sides of fusiform gyrus, and decreased connectivity between the subgenual cingulate cortex and the left cerebellum found in the patients with major depression in comparison to the healthy subjects might be related to abnormal emotional and cognitive processing of depressed patients.

We examined the inter-annual changes in the community structure of fish in the Yeosu coast during the spring fishing period (May June) from 2008 to 2015. Using a both sides fyke net, we collected 74 taxa, of which the dominant species was Trachurus japonicus. In the years 2009-2010 and 2015, when the relative abundance of T. japonicus decreased, the fish species diversity increased, as estimated from the rarefaction curve and beta-diversity, resulting in a significant difference in the fish community structure between two year groups: one comprising 2009-2010 and 2015 and the other comprising 2008 and 2011-2014. T. japonicus may be a keystone species that plays a critical role in temporal changes in the community structure of fish caught by fyke nets along the southern coast of Korea. Obvious modes in the length-frequency of T. japonicus smaller than fork length (FL) 10 cm were observed continually during the study, while the frequency of T. japonicus bigger than FL 15 cm declined rapidly after 2010. The new recruitment of smaller T. japonicus before and after 2010 appeared beginning in June and May, respectively.
