The purpose of this thesis is to find out how the upper garment styles in the Ancient East and est had been influenced with each other. Analytical studies conclude the fellowing findings: 1) Upper garment styles in the feat Asia and the Egypt already highly developed in 28th century B.C. and show us the original style of the wrap-over to the left and that of the round neckline(曲領). Upper garment of the open in the center front shown in Babylonia in 18th century B.C. had been inherited to the caftan of the Hebrew and later succeeded to the Persia. 2) The tunic styles of the round neckline, the wrap-over to the left and the open in the cotter front, which were the basic styles of the upper garment, had teen widely accepted to the central Asia and the East Asia, as well as the Northern Europe, from the West Asia. 3) The styles of the wrap-over to the right originated from China since it had begun to show in the Shang Dynasty(商代, 殷代). 4) The East and the West costumes had been very much intermixed in 4th century B.C. Alexander the Great of Macedoria in 4th century B.C. expanded his territory to the central Asia and built up the Bacteria, when the most western civilization had been greatly transmitted to the Orient. Meanwhile the tunic being clad in the West and Central Asia began to be worn by soldiers in the period of the Warring States in China (326-299 B.C.) and afterwards worn even by civil officials since the age of the T'ang Dynasty of China. 5) The Upper garments of the open in the center front, the wrap-over to the right, the wrap-over to the left and the round neckline were found in Korea, which mean that the upper garment styles in the Ancient Korea were intermixed of the factors from the West Asia, the central Asia and the East Asia. 6) The styles of costume in the East Asia were influenced by the West Asia through the central Asia. The upper garment styles Europe were also influenced by the West Asia. Thus the upper garment styles in the Ancient East and West had been mutually affected with each other.

The purpose of this study is to document an unidentified velvet fabric which is located in the Museum. The investigation was conducted by analyzing color, weaving technique. pattern of the study object. To identify the origin of the object, many references about color trends, construction methods and patterns were accessed. Two comparative objects which were dating from 1600 to 1699 in the Museum of F.I.T. were selected since they are similar to the study object. The results of this study can be summarized as follows; (1) The type of this study object is 'cut and voided velvet'. It is obtained establishing the motif as areas of cut pile so as to form a pattern, while leaving other areas of the grounded weave without pile. Two flowers and two tulips with S curved stems are composed as one unit in the vertical direction. (2) The colors used in this study object. which are ivory, smoke blue, medium orange, and yellow. are part of a new trend color in the $17^{th}$ century. (3) The vertical undulating stripe patterns are also of significance in this fabric. They seemed to be contemporary with the serpentine line which was common since the $15^{th}$ century and the vertical stripes pattern which appeared from the $16^{th}$ century. (4) The stylized tulip patterns of this study object began to appear in the early $17^{th}$ century. The stems and leaves of this patterns are less sinuous than the floral motifs of the later $17^{th}$ century. Therefore, the study object is dated to early in $17^{th}$ century because of the color combination. stripes. stylized tulips, leaves. and stems are showing the characteristics of this period.

Purpose: This study aimed at developing an artificial neural network (ANN) model to predict the optimal start moment of the setback temperature during the normal occupied period of a building. Method: For achieving this objective, three major steps were conducted: the development of an initial ANN model, optimization of the initial model, and performance tests of the optimized model. The development and performance testing of the ANN model were conducted through numerical simulation methods using transient systems simulation (TRNSYS) and matrix laboratory (MATLAB) software. Result: The results analysis in the development and test processes revealed that the indoor temperature, outdoor temperature, and temperature difference from the setback temperature presented strong relationship with the optimal start moment of the setback temperature; thus, these variables were used as input neurons in the ANN model. The optimal values for the number of hidden layers, number of hidden neurons, learning rate, and moment were found to be 4, 9, 0.6, and 0.9, respectively, and these values were applied to the optimized ANN model. The optimized model proved its prediction accuracy with the very storing statistical correlation between the predicted values from the ANN model and the simulated values in the TRNSYS model. Thus, the optimized model showed its potential to be applied in the control algorithm.

The study focuses on the quality assessment of Black Bengal buck semen preserved at chilled condition. In this in vitro trial, collected semen from Black Bengal bucks was preserved at chilling temperature ($4{\sim}5^{\circ}C$) in tris-glucosecitrate yolk medium of 1:5 ratios for four days. Artificial Vagina (AV) method was utilized to collect semen from buck. General evaluation of semen includes the color, mass activity and density were measured by direct visual examination. However, computer-assisted sperm analysis (CASA) and phase contrast microscopy were used to figure out the motility (%), hyper-activated (HYP) motility (%) and number of abnormal spermatozoa (%) initially, and at every 24 h intervals. The result revealed that spermatozoa preserved at chilling temperature showed significantly (P<0.05) lower motility and HYP motility with the progression of preservation. The number of phenotypically abnormal spermatozoa significantly (P<0.05) increased following preservation. Although significant positive correlation (r=0.945; P<0.05) was existed between % motile and % HYP motile spermatozoa however, the % of morphologically abnormal spermatozoa was negatively correlated with % motile (r=-0.997; P<0.05) and % HYP motile spermatozoa (r=-0.946; P<0.01). Therefore, we concluded that the quality of chilled semen progressively losses its viability and doesn't remain useable after certain period of preservation with respect to its motility and morphology.

Purpose: The aim of this study was to investigate the satisfaction of newly graduated nurses with educational programs and their experiences in role transition. Methods: Data were collected from November 1 to December 15, 2018 and 483 new graduate nurses working at 15 tertiary hospitals and 10 general hospitals participated. For data collection, self-report questionnaires including the Casey-Fink Graduate Nurse Experience Survey tool and satisfaction with education were used. Data were analyzed using descriptive statistics, t-test, and one-way analysis of variance. Results: Satisfaction with education ranged from 3.09 to 3.27, and satisfaction with preceptors was 3.45(maximum 4). The skill that new nurses ranked as most difficult during the first 3 months was charting/documentation, and throughout a whole year, the top 4 difficult skills were cardiopulmonary resuscitation/emergency response, ventilator care, end-of-life care, and prioritization/time management. In comfort/confidence, new graduates felt most comfortable with support and least comfortable with patient safety. More than 50 percent of new graduates experienced stress during role transition, and the most frequently experienced stressors were related to job performance and personal life. Levels of satisfaction with education and comfort/confidence differed according to the hospital type and number of preceptors for new nurses. Conclusion: In order to facilitate the transition of new graduate nurses to professional nurse, an extended period of education, systematic and standardized transition programs, and continuous support during the first year of practice are required.

Background Preoperative computed tomography angiography (CTA) of the abdominal wall vessels is used when planning free flap breast reconstruction (FFBR) because it provides a surgical road map which facilitates flap harvest. However, there are few reports on the effect of abnormal findings on the operative plan. Methods We conducted a retrospective study of all FFBRs performed at a tertiary referral center over a 6-year period (November 2011 to June 2017). One consultant radiologist reported on the findings. Details on patient demographics, CTA reports, and intraoperative details were collected. Results Two hundred patients received preoperative CTAs. Fourteen percent of patients (n=28) had abnormal findings. Of these findings, 18% were vascular anomalies; 36% tumorrelated and 46% were "miscellaneous." In four patients, findings subsequently prevented surgery; they comprised a mesenteric artery aneurysm, absent deep inferior epigastric (DIE) vessels, bilateral occluded DIE arteries, and significant bone metastases. Another patient had no suitable vessels for a free flap and the surgical plan converted to a pedicled transverse rectus abdominis musculocutaneous flap. The remaining incidental findings had no impact on the surgical plan or appropriateness of FFBR. More than one in 10 of those with abnormal findings went on to have further imaging before their operation. Conclusions CTA in FFBR can have a wider impact than facilitating surgical planning and reducing operative times. Incidental findings can influence the surgical plan, and in some instances, avoid doomed-to-fail and unsafe surgery. It is therefore important that these scans are reported by an experienced radiologist.

The purpose of this study is to compare soil $CO_2$ efflux between burned and unburned sites dominated by Pinus densiflora forest in the Samcheok area where a big forest fire broke out along the east coast in 2000 and to measure soil $CO_2$ efflux and environmental factors between March 2011 and February 2012. Soil $CO_2$ efflux was measured with LI-6400 once a month; the soil temperature at 10 cm depth, air temperature, and soil moisture contents were measured in continuum. Soil $CO_2$ efflux showed the maximum value in August 2011 as 417.8 mg $CO_2m^{-2}h^{-1}$ (at burned site) and 1175.1 mg $CO_2m^{-2}h^{-1}$ (at unburned site), while it showed the minimum value as 41.4 mg $CO_2m^{-2}h^{-1}$ (at burned site) in December 2011 and 42.7 mg $CO_2m^{-2}h^{-1}$ (at unburned site) in February 2012. The result showed the high correlation between soil $CO_2$ efflux and the seasonal changes in temperature. More specifically, soil temperature showed higher correlation with soil $CO_2$ efflux in the burned site ($R^2$ = 0.932, P < 0.001) and the unburned site ($R^2$ = 0.942, P < 0.001) than the air temperature in the burned site ($R^2$ = 0.668, P < 0.01) and the unburned site ($R^2$ = 0.729, P < 0.001). $Q_{10}$ values showed higher sensitivity in the unburned site (4.572) than in the burned site (2.408). The total soil $CO_2$ efflux was obtained with the exponential function between soil $CO_2$ efflux and soil temperature during the research period, and it showed 2.5 times higher in the unburned site (35.59 t $CO_2ha^{-2}yr^{-1}$, 1 t = $10^3$ kg) than in the burned site (14.69 t $CO_2ha^{-2}yr^{-1}$).

Purpose: Mortality Provability Model (MPM) II is a model for predicting mortality probability of patients admitted to ICU. This study was done to test the validity of MPM II for critically ill neurological patients and to determine applicability of MPM II in predicting mortality of neurological ICU patients. Methods: Data were collected from medical records of 187 neurological patients over 18 yr of age who were admitted to the ICU of C University Hospital during the period from January 2008 to May 2009. Collected data were analyzed through $X^2$ test, t-test, Mann-Whiteny test, goodness of fit test, and ROC curve. Results: As to mortality according to patients' general and clinically related characteristics, mortality was statistically significantly different for ICU stay, hospital stay, APACHE III score, APACHE predicted death rate, GCS, endotracheal intubation, and central venous catheter. Results of Hosmer-Lemeshow goodness-of-fit test were MPM $II_0$ ($X^2$=0.02, p=.989), MPM $II_24$ ($X^2$=0.99 p=.805), MPM $II_48$ ($X^2$=0.91, p=.822), and MPM $II_72$ ($X^2$=1.57, p=.457), and results of the discrimination test using the ROC curve were MPM $II_0$, .726 (p<.001), MPM $II_24$, .764 (p<.001), MPM $II_48$, .762 (p<.001), and MPM $II_72$, .809 (p<.001). Conclusion: MPM II was found to be a valid mortality prediction model for neurological ICU patients.

Ch'ang-Ts'al-Ts'un is a rural Village near Lung-jing City in Yen-pien Korean Autonomous Province of China. It was formed about 100 years ago by Korean Immigrants and has been developed maintaing the characteristics of traditional Korean architecture. Therefore investigating the spatial structure of this village is a meanigful work to confirm and explore one branch of Korean architecture. This study aims at analyzing the spatial structure of the village using direct data collected from the field work and indirect data from books and maps. The field work consists of on-the-site survey of the village layout, interviews of residents, observation notes and photography. Ch'ang-Ts'ai-Ts'un is located 360-370 m high above the sea level and at the side of a long valley. A river flows in the middle of the valley and relatively flat arable land exists at the both sides of the river. The location of the village related to the surrounding river and mountains suggests that the site of the village was chosen according to Feng-Shui, Chinese and Korean traditional architectural theory. The main direction of the house layouts is South-western. The village has been growing gradually until today. Therefore it is meaningful to make the village layout before Liberation(1946 A.D.) because the characteristics of Korean architecture prevailed more in that period. The area of the previous village is limited to the west side of the creek. New houses were later added to the east of the creek, forming a 'New Village'. Previously the village was composed of 3 small villages: Up, Middle and Down. Also the main access roads connecting the village with the neighboring villages were penetrating the village transversely. Presently the main access road comes to the village longitudinally from the main highway located in front of the village. The retrospective layout shows the existence of well-formed Territory, Places and Axes, thus suggesting a coherent Micro-cosmos. The boundary of imaginery territory perceived by present residents could be defined by linking conspicous outside places sorrounding the village such as Five-mountains, Front-mountain, Shin-dong village, Standing-rock, Rear-mountain and Myong-dong village. Inside the territory there are also the important places such as Bus-stop, Memorial tower of patriots, Road-maitenance building and the village itself. And inside it 5 transverse and 1 longitudinal axes exist in the form of river, roads and mountains. The perceived spatial structure of the village formed by Places, Axes and Territory is geometrical and well-balanced and suggests this village is fit for human settlement. The administrative area of the village is about 738 ha, 27 % of which is cultivated land and the rest is mountain area. Initially the village and surrounndings were covered with natural forest But the trees have been gradually cut down for building and warning houses, resulting in the present barren and artificial landscape with bare mountains and cultivated land. At present the area of the village occupied by houses is wedge-shaped, 600 m wide and 220 m deep in its maximum. The total area of the village is $122,175m^{2}$. The area and the rate of each sub-division arc as follow. 116 house-lots $91,465m^{2}$ (74.9 %) Land for public buildings and shops $2,980m^{2}$ (2.4 %) Roads $17,106m^{2}$ (14.0 %) Creek $1,356m^{2}$ (1.1 %) Vacant spaces and others $9,268m^{2}$ (7.6 %) TOTAL $122,175m^{2}$ (100.0 %) Each lot is fenced around with vertical wooden pannels 1.5-1.8 m high and each house is located to the backside of the lot. The open space of a lot is sub-divided into three areas using the same wooden fence: Front yard, Back yard and Access area. Front and back yards are generally used for crop-cultivation, the custom of which is rare in Korea. The number of lots is 116 and the average size of area is $694.7m^{2}$. Outdoor spaces in the village such as roads, vacant spaces, front yard of the cultural hall, front yard of shops and spacse around the creek are good 'behavioral settings' frequently used by residents for play, chatting, drinking and movie-watching. The road system of the village is net-shaped, having T-junctions in intersections. The road could be graded to 4 categories according to their functions: Access roads, Inner trunk roads, Connecting roads and Culs-de-sac. The total length of the road inside the village is 3,709 m and the average width is 4.6 m. The main direction of the road in the village is NNE-SSE and ESE-WNW, crossing with right angles. Conclusively, the spatial structure of Ch'ang-Ts'ai-Ts'un village consists of various components in different dimensions and these components form a coherent structure in each dimension. Therefore the village has a proper spatial structure meaningful and appropriate for human living.

This article examines the distributional characteristics of the return of Chinese stock market indices. The majority of previous empirical researches have tended to focus upon the simple stock market index. However, this study focuses on the four indices which represent the characteristics of each stock market index. The empirical findings indicate that the returns of the four chinese indices are not normally distributed at conventional levels. The Ljimg-Box -statistics indicate the returns of the index of A shares are not serially autocorrelated. However, the returns of the index of B shares are serially autocorrelated. The empirical findings also indicate returns of the four chinese indices are not serially autocorrelated. The statistics of Regression Specification Error Test and ARCH indicate the returns of all four indices are not serially linear. The findings also indicate that E- GARCH model is the most fittest model for the returns of the four chinese indices and the forecast error can be reduced by using student t distribution rather normal distribution.
