This study was conducted to develop a japonica-type rice cultivar with brown planthopper (BPH) resistance using DNA markers. A doubled haploid (DH) population consisting of 120 pure-lines was established by anther culture of $F_1$ hybrids between 'Samgang', a Tongil type BPH resistance cultivar, and 'Nagdong', a japonica cultivar. To determine the map position of genes responsible for BPH resistance in rice, a genetic map was constructed based on 120 DH lines. A total of 162 molecular markers were classified into 12 linkage groups, covering 1,884 Kosami centimorgan (cM) with an average of 11.6 cM. Five QTLs (qBPR3, qBPR6, qBPR7, qBPR8, and qBPR12) associated with BPH resistance were identified and mapped on chromosomes 3, 6, 7, 8, and 12, respectively, using the genetic map constructed in this study. To analyze the relationship between BPH resistance and agronomic traits, a total of eight QTLs related to the agronomic traits were detected on 12 rice chromosomes. In an analysis of relationships, three QTLs (qBPR3, qBPR7, and qBPR8) showed a linkage with tested agronomic traits. A QTL (qBPR3) located on chromosome 3 (RM282-3023) was closely linked to culm length (qCL3). The QTL (qBPR8) for BPH resistance on the short arm of chromosome 8 also overlapped the region detected in culm length (qCL8).

This study analyzed the relationships among actual body types, perceived body types, body-image discrepancy(difference between perceived and ideal body), and body satisfaction, and their effects on jacket fit satisfaction at 17 body parts of women in their 20s. To apprehend the actual body type of subjects, total 18 items were measured according to the anthropometric method of the 6th anthropometric survey project. The relationship between body-image discrepancy and body satisfaction was correlated in all body parts. Body-image discrepancy and body satisfaction were more affected by perceived body size than actual body size. The fit satisfaction level of the jacket was found to be lower as the discrepancy between the body type and the ideal body type was recognized. As the waist girth, hip girth, armscye girth, and upper arm girth were smaller, the height was taller, bust girth and breast size were larger, these body sizes were considered as closer to the ideal body shape and the jacket fit of the area was more satisfied. When the perceived body sizes and the actual body sizes were compared, the women in their 20s tended to perceive their waist, abdomen, and hip as larger, their shoulder length and front/back interscye as longer, their breast size as smaller, and their waist height as lower than the actual size.

The purpose of this study is to propose changes that can be made to improve nurse uniforms in terms of outfit and functionality based on actual wearing conditions and nurse's preference. The proposed nurse uniform was composed of a blouse and pants. The design was as follows: the blouse had short set-in sleeve with China collar, a princess line, and it came down to middle hip. Armhole action pleats and back inverted pleats were embedded for convenient arm movements. The pants waist had a rubber band at the back waist, and the crotch length and the knee width were increased for activity. To make the pocket more accommodative, separate pocket slots treated with silicone were added to prevent belongings from coming out of the pocket. The pink tone of the uniforms, as well as the stripes on the blouses and spandex incorporated pants were based on nurses' preference. the nurse uniforms were produced after measuring the size of women in the age of 25 to 29, and the uniform patterns were corrected after two wearing experiments. Wearing test was examined in terms of appearance and functionality. For appearance, experts gave the uniforms a mean rating of 4.30, and nurses gave a mean rating of 4.00. Functionality was evaluated in terms of ease of activity and storage aspects. The total mean of ease of activity in nursing service was 4.30, whereas the evaluation of storage in terms of pocket position and convenience was 3.80.

Objective: To achieve optimal fit of implant, it is necessary to bend the implant during spine surgery. Bending procedure may decrease stiffness of plate especially made of titanium and stainless steel. Typically titanium suffers adverse effects including early crack propagation when it is bent. We investigate whether 6 degree bending of titanium plates would decrease the stiffness after full cyclic loading by comparing with non-bending titanium plates group. Methods: Authors experimented 40 titanium alloy plates of 57mm in length, manufactured by 5 different companies. Total 40 plates were divided into two groups (20 bent plates for experimental group and 20 non-bent plates for control group). Twenty plates of experimental group were bent to 6 degree with 3-point bending technique and verified with image analyzer. Using the electron microscope, we sought for a initial crack before and after 3-point bending. Mechanical testing by means of 6000 cyclic axial-compression loading of 35N in compression with moment arm of 35mm-1.1 Nm was conducted on each plate and followed by the electron microscopic examination to detect crack or fissure on plates. Results: The stiffness was decreased after 6000 cyclic loading, but there was no statistically significant difference in stiffness between experimental and control group. There was no evidence of change in grain structure on the electron microscopic magnification. Conclusion: The titanium cervical plates can be bent to 6 degree without any crack or weakness of plate. We also assume that minimal bending may increase the resistance to fatigue fracture in cervical flexion-extension movement.

Objective and Background: Due to increase in Musculoskeletal Disorders (MSDs) relating to computer use, a number of ergonomics recommendations have been proposed in order to tackle this problem. However, some of these recommendations have been conflicting. Method: This study was to survey the VDT (Visual Display Terminal) use of office workers. The subjects were 452 workers at 13 places of business and the data were collected by self-administered questionnaire. Results: As a result, prevalence of self-reported MSDs of all VDT workers was 90.2% and shoulder took up 57.0% and neck 38.3% by symptom part of body. The population of computer use of more than 6h/day was 84.5%, and 33.8% also reported using the VDT 2~3h/day without the rest time. Desktop computer users were 95.6%, and a 17-inch monitor accounted for 42.0% among the desktop users. As a result of satisfaction survey on overall computer work, 21.1% of the total respondents said satisfied, desk complaint was about 24.6%, and chair complaint was 33.4%. Despite the importance of computer environment, satisfaction was from fair to uncomfortable. Conclusion and Application: In conclusion, office workers are prone to the MSDs due to their work environment. Additionally, this study found that task was a significant effect for the majority of dependent variables, and therefore, the improvement of computer workstations work environment is urgent, and the improvement of desk height adjustment, chair seat size (length, width), backrest condition, location of keyboard (mouse) and arm rest is required.

The purpose of this study is to compare the constitutions comparatively among Korean, Chinese and Chosunjok college women and thereby, provide for some basic data helpful to the development of export apparels befitting the Chinese consumers, For this purpose, Korean, Chinese and Chosunjok college women aged between 17 and 24 were sampled to be subject to body measurements. The measurement data obtained were indexed for each part of the body to set a total 29 constitutional indices, which were analyzed by factor dictating the major shapes of body, Thus, based on the constructed, the differences of constitution among three groups were comparatively analyzed. The results of this study of this study can be summarized as follows; It was found through this study that Korean college women had thickest neck compared with body size and had longer lower limbs compared with stature, Moreover, their lower body was absolutely longer than the other two groups, and thus, Korean college women were found slimmest. On the other hand, Chinese college women had most voluminous chest turned over with shorter and thicker body. they were obesest. Chosunjok college women had longest upper body but shortest breast length. Their lower body was obesest, and their body was longer compared with stature. Moreover, Chosunjok college women's lower limbs were shortest, while their arm scyes were small nearest body type.

Background The radial forearm free flap (RFFF) has remained a leading choice of many plastic surgeons as a fasciocutaneous flap due to its versatility, pedicle length, and simple elevation technique. However, donor site morbidity has led many reconstructive surgeons to limit their use of the RFFF and to use other flaps instead. We propose that using a narrow RFFF (nRFFF) decreases the aesthetic and functional morbidity of the donor site. Methods We report our experiences with the nRFFF from April 2012 through May 2015 at the Department of Plastic, Reconstructive, and Hand Surgery at Liaquat National Hospital, Karachi. The donor defects were closed primarily. The Stony Brook Scar Evaluation Scale and comparison with the contralateral hand were used to assess aesthetic and functional outcomes, respectively. Results A total of 24 patients underwent nRFFF procedures during the study period. The donor arm showed excellent motor function in 22 cases (91.7%), and very good function in the remaining two cases (8.3%). The aesthetic outcomes were excellent in four patients (16.6%), very good in eight patients (33.3%), good in 10 patients (41.6%), and fair in two patients (8.3%) who developed a hypertrophic scar. All flaps were successful and there were no cases of partial or complete loss. Conclusions For small to medium-sized soft tissue defects, the nRFFF had acceptable outcomes due to its thinness, pliability, and major reduction in donor site aesthetic and functional morbidity.

Background: Authors modified the traditional continuous axillary brachial plexus block technique of Selander for purpose of increasing success rate and decreasing complications by use of commercial epidural anesthesia set. Method: Thirty-nine patients scheduled for upper extremity operations were injected with 40 ml of anesthetic solution by axillary perivascular technique, using 23~25G immobile needle at 2 cm from the pectoralis major. Tuohy needle was immediately introduced at 4 cm from the pectoralis major and pierced the expanded neurovascular sheath at an angle of 30 degree to the skin. The "pop" was well noted well. Needle was advanced 0.5 to 3.0 cm and epidural catheter introduced through the needle. After removal of needle, occlusive dressing was done. Tip of catheter and spread of solution were demonstrated by fluoroscopy with contrast dye after completion of procedure. Result: Catheter insertion was successful at first attempt for all case. Total length of insertion was from 6 to 13($10.0{\pm}1.7$) cm. Tip of catheter was placed in infraclavicular space(66.7%), about the humeral head(17.9%) and in upper arm in 3 cases as U-shape(7.9%). Catheters were maintained for $6.7{\pm}2.6$(3-12) days. There were no complications such as: perforation of major vessels, needle trauma to nerve, infection, bleeding or hematoma. Conclusion: This study demonstrated continuous axillary brachial plexus block with epidural anesthesia set is safe, easy and convenient modification of technique of Selander.

The study aimed to evaluate the appearance of the men's work clothes jumpers developed to suggest the prototype work clothes jumper patterns by using the 3-D clothing simulation technology. The 3-D simulated clothing images considered the upper body features of men in the age range between 20 and 59 in South Korea. A questionnaire survey conducted previously suggested a basic jumper style with shirt collar and snap opening cuffs for the heavy industry workers; and discomforting parts of the work clothes jumper of the subject workers have been referred to for the experimental jumper appearance test. Besides, defining the measurements of men's upper bodies enabled to generate the men's 3-D virtual models representing each age group's average body feature. The significant body measurement factors for men's 3-D body modeling and jumper pattern-making were stature for the height factor; chest, waist and hip circumferences for the circumference factor; waist back, hip and arm lengths and interscye front/back for the length factor; and back neck breadth for the breadth factor and armscye and scye depths for the depth factor. The men's body measurements of 30's were implemented to three experimental jumper pattern-making methods, i.e. the 1st method using the relations based on stature and chest circumference; the 2nd method using the direct body measurements; and the 3rd method adopting the maximum ease amount of given body measurements whether relations or direct measurements except the direct measurement of scye depth. A comparison among the three experimental jumpers' simulated images highlighted that the appropriate ease amount of the jumper gained higher scores in terms of the jumpers' front, side, back and sleeve parts and the total silhouettes. Therefore the 3rd experimental jumper was finally selected for the heavy industry workers.

The purpose of this study is to provide total data of real body-type and self-evaluation about it. The subjects were 614 middle-aged women between 35 and 59 years old. Data were collected through measurement and a questionnaire survey on self-evaluation. The results of self-evaluation of body are as follows; 1. As the result of the recognition degree analysis, people consider themselves thicker, shorter or smaller than what they really we, regardless of ages and types. In addition, the women of younger group rather than the women of older group consider themselves bigger/thicker and shorter than what they really are. They think that the items of waist girth, abdominal girth, hip girth, upper arm girth. and thigh girth are thicker than the other items, however, among girth items the size of bust girth is smaller than the other items. The women of the late middle-aged group consider their somatotype thicker/bigger and shorter than the women of the early middle-aged group do. 2. As the result of body cathexis for each part, women in general rum out themselves not to be satisfied with their body parts, regardless of ages and types. Particularly, they are not satisfied with abdominal girth, weight, hip girth. According to the age bracket, the women in the older group are more satisfied than the women of younger group in terms of their body. According to somatotype, women in tall and slim groups are more satisfied with their body. The women of the early middle-aged group turn out not to be satisfied with girth items while the women of the late middle-aged group are not satisfied with length items.
