Clothing fitness is strongly required in the apparel industry, and draping is an effective tool to increase fitness to the wearers. A more sophisticated and systematic information of the somatotype, accordingly, is necessary for better cress form design. This study was performed to provide fundamental data on middle aged women's upper torso for dress form designers and pattern makers by classifying the somatotype based on each individual's lateral view, and analyzing the characteristics of their somatotype. Data were analyzed by factor analysis, cluster analysis, analysis of variance. Factor analysis was used to 23 items from photometric measurment and cluster analysis was applied for classification of upper torso forms. Through cluster analysis using 5 factor scores, 3 somatotypes were categorized from th lateral view 1) Type I was straight somatotype in which the plumb line passes throught the lobe of the ear, the shoulder joing and the mid abdominal region laterally. This type of woman was slender and shorter than average. 2) Type II was bending somatotype in which the upper portion of upper torso is bent forward. This type of woman was taller and fatter than average. 3) Type III was swayback somatotype in which the upper portion of protruding point on the back is bent forward but the lower portion of protruding point had characteristic of turning over somatotype. This type of woman had storter length on the front and longer lenght on the back, slender type and flat chest.

For the efficient operation and maintenance( 0 & M), irrigation facilities were graded on the basis of their indices related to the 0 & M condition and the characteristics of reservoirs managed by Farmland Improvement Association(FIA) were examined. The results obtained are summarized as follows : 1. Characteristics of reservoirs include effective storage capacity, irrigation area, basin area, height and length of bank. Each characteristic is scored by the principle component analysis method. Variables which compose one index are categorized on the basis of their unit and each variable is scored so that the score of each unit sums to 100 for each index. 2. The Optimum MAnagement System of Irrigation Facilities(OMASIF) for Pyoungtaek area was developed by connecting general data of the irrigation facilities to image data. The database system is divided into three tables; LookUp Table, Facility Table, and Image Table. Image Table is again divided into five sub-tables, Image Table, Construction Cost Table, Acreage Table, 0 & M Cost Table, and Specification Table. 3. The evaluating criteria for the 0 & M of irrigation facilities can be established using the OMASIF. Irrigation facilities evaluated as poor state by the criteria should be repaired.

The purpose of this study was to develop on east-west nursing intervention program. This study was conducted to identify the effectiveness of using facial meridian points for massage nursing intervention on the recovery of facial paralysis for 46 patients (22 for experimental group). All had suffered from strokes, and were also admitted to the division of oriental medicine in K University Hospital. Method: Data was collected from February 1st to December 31st of 2000. This study used a quasi experimental, non-equivalent control group pre-test and post-test design. The recovery of facial paralysis was measured by the difference between left and right facial length, observation and self report on a seven point scale, and facial discomfort by a facial scale after 6-7 facial massages in a two week period. Data was analyzed using the SPSS package program with x2 and t test. Result: The result of this study are as follows; The experimental group who received the facial meridian massage showed higher scores in recovery of facial paralysis (t=2.72, p=.009), and a smaller difference between left and right facial strength than those in control group (t=2.26, p= .29). The discomfort of the facial area in the experimental and control group showed no significant differences. Conclusion: These findings indicate that a facial meridian points massage could be an effective nursing intervention to the recovery of facial paralysis. This study contributes in developing an east-west nursing intervention with the oriental meridian theory and western massage therapy.

Purpose: To identify risk factors for surgical site infections in patients undergoing general surgery, to analyze the prolonged hospital stay and extra cost for antibiotics, and to provide basic data for control of surgical site infections. Method: Surgical site infection was defined using the definition of the CDC and the data were analyzed by $x^2$-test and unpaired t-test. Results: The prevalence of surgical site infections was 9.7%, and it was related to wound class, duration of operation, number of operations, whether the operation was an emergency, trauma, drains, preoperative stays, presence of remote infection during operative period, and previous history of recent surgery. The mean duration for post-operative stay when a surgical site infection occurred was 9.5 days and in 56.9 % of the patients the surgical site infection appeared 7 days after the operation. Post-operative stays for infected patients were 20.3 days longer than that of uninfected patients. The mean cost of antibiotics for infected patients was higher than that for uninfected patients by 561,067 won per person. Conclusion: Surgical site infection results in an increased length of stay and extra-cost, thus, hospitals need to create strategies to reduce nosocomial infections through effective infection surveillance and by considering factors related to surgical site infections.

Purpose: This study was to evaluate the effects on the heart rate and respiration rate of preterm infants when providing auditory stimulation on them. Methods: The design of this study was a nonequivalent control group pretest-posttest design in a quasi experimental study. Forty preterm infants were assigned to experimental and control groups : 20 in the auditory and 20 in the control group. The data were collected from May 2014 to October. The auditory stimulation was created by using an audio music tape provided 20-minute per day for 7 consecutive days. In data analysis, SPSS WIN 21.0 program was utilized for descriptive statistics, repeated measurement anova and Mann-Whitney. Results: General characteristics of the two groups showed no significant differences, thus two groups were found to be homogenous. There were no significant differences in heart rate and respiration rate between the auditory and control groups. Conclusion: The effect of auditory stimulation for 7 days was not effective in decreasing heart rate or respiration rate in premature infants. Therefore, the type and length of music therapy must be developed for the improvement of vital signs in preterm infants who were hospitalized in a neonatal intensive care unit.

In this paper, fatigue tests were carried out at stress test levels of 461 MPa, 441 MPa, and 431 MPa by using smooth specimen of$2_{1/4}$ Cr-1 Mo steel with the stress ratio(R) of 0.05. The initiation, growth and coalescense process of the major cracks and sub-cracks among the fatigue cracks on the smooth specimen are investigated and measured under each stress level at a constant cycle ratio by the replica technique with optical microscope. Some of the important results are as follows: In spite of the difference of stress levels, the major crack data gather into a small band in the curve of surface crack length and crack depth against cycle ratio N/Nf. The sub-crack data, however, deviate from the band of the major crack. The growth rates, da/dN, of major and sub-crack plotted against the stress intensity factor range, ${\Delta}K$, have the tendency to be compressed on a relatively small band. But it is more effective to predict fatigue life through major cracks. The propagation behavior of surface microcracks on the smooth specimens coincides with that of the specimen having an artificial small surface defect or through crack.

The line simplification method based on the turning function is studied in this paper for conversion of ground plan data to geospatial data to update the digital map. This method eliminate vertices effectively by estimating the length and the angle between the vertices based on the turning function which is useful to express the shape of linear feature. As the result, this method shows high shape similarity, high elimination rate of vertices and 100% of satisfaction degree to the drawing rules. Thus this line simplification method is judged to be effective in updating the digital map with ground plans.

This research aims at finding out situation on purchasing clothes for kids, size recognition and fitting to provide basic data in order to establish standard sizes for kids' clothes. A survey was conducted to 360 mothers who have children ranging from first to third grade in elementary school on clothes purchasing method, wearing situation, criteria in deciding size and fitting preference. In terms of data analysis, frequency, percentage, mean, $X^2$-test, ANOVA and Duncan-test were used via SPSS PC program. The result is as follows; 1. While the recognition on brand was high, the recognition on body size was low: as a result, it is believed that it would be effective to mark the weight along with the brand. 2. Many times, they would select one or two size bigger on all items and they would go for a regular or one that fits as far as filling is concerned showing that it is different from adult clothes. 3. As far as obese kids, they would choose based on the diameter, so the diameter item is right but they are too long in general. The length question should be given special attention when manufacturing clothes for obese kids.

Purpose: The purpose of this study was to identify the risk factors that influence surgical site infections after surgery. Methods: This study was a retrospective research utilizing Electronic Medical Records. Data collection targeted 4,510 adult patients who had 8 different kinds of surgery (gastric surgery, colon surgery, laparoscopic cholecystectomy, hip & knee replacement, hysterectomy, cesarean section, cardiac surgery) in 4 medical care departments, at one general hospital between January 2006 and December 2011. Multivariate logistic regression analyses were used to identify the risk factors affecting surgical site infections after surgery. Results: Risk factors for increased surgical site infection following surgery were confirmed to be age (OR=1.59, p<.001), BMI (Body Mass Index)(OR=1.25, p=.034), year of operation (OR=2.45, p<.001), length of operation (OR=3.06, p<.001), ASA (American Society of Anesthesiology) score (OR=1.36, p=.025), classification of antibiotic used (OR=2.77, p<.001), duration of the prophylactic antibiotics use (OR=1.85, p<.001), and interaction between classification of antibiotic used and duration of the prophylactic antibiotics use (OR=1.90, p=.016). Conclusions: Results suggest that risk factors affecting surgical site infections should be monitored before surgery. The results of this study should contribute to establishing effective infection management measures and implementing surveillance systems for patients who have actual risk factors.

Available methods to determine the ultimate bearing capacity of shallow foundations may not be accurate enough owing to the complicated failure mechanism and diversity of the underlying soils. Accordingly, applying new methods of artificial intelligence can improve the prediction of the ultimate bearing capacity. The M5' model tree and the genetic programming are two robust artificial intelligence methods used for prediction purposes. The model tree is able to categorize the data and present linear models while genetic programming can give nonlinear models. In this study, a combination of these methods, called the M5'-GP approach, is employed to predict the ultimate bearing capacity of the shallow foundations, so that the advantages of both methods are exploited, simultaneously. Factors governing the bearing capacity of the shallow foundations, including width of the foundation (B), embedment depth of the foundation (D), length of the foundation (L), effective unit weight of the soil (${\gamma}$) and internal friction angle of the soil (${\varphi}$) are considered for modeling. To develop the new model, experimental data of large and small-scale tests were collected from the literature. Evaluation of the new model by statistical indices reveals its better performance in contrast to both traditional and recent approaches. Moreover, sensitivity analysis of the proposed model indicates the significance of various predictors. Additionally, it is inferred that the new model compares favorably with different models presented by various researchers based on a comprehensive ranking system.
