This experiment was carried out to determine the effect of storing method and wrapping frequency on the quality of round baled rice straw silage at experimental field of Grassland and Forage Crops Division, National Livestock Research Institute, RDA, Suwon fro 1999 to 2000. Storing methods consisted of erect and lay type, and wrapping frequencies were composed to 2, 4, 6, 8 and 10 film layers. there were no significant difference in feed value between storing methods, but acidity of lay type was significantly higher than that of erect type. According to the wrapping frequency, crude protein(CP) content of 2 film layers treatment was lowest during 6 month storing periods, and that of 4 film layers treatment was lowest during 10 month storing periods. The two film layers treatment which was stored for 10 month was impossible for ruminant to feed it, because it was rotten severely. Storing for 6 month, 2 film layers treatment represented highest pH value by 8.23 and storing for 10 month, 4 film layers treatment showed highest pH value by 7.17. Most of silage ranked grade 3 in quality grade. According to this experiment, it was recommended that application of round bale silage system to fresh rice straw should wrap above 4 film layers for 6 month, and above 6 film layers for 10 month storing periods.
A wrapped fruit-vegetable can restrain from evaporating its water, help to be supplied with a little fresh air, prevent from injuring and damaging during transporting to other positions. Therefore, this study was carried out to develop an automatic wrapping system specifically tailored to pack up from one to four numbers of long type fruit-vegetable in wrap foil. Performance tests of the system were conducted by using three different kinds of fruit-vegetable (cucumber, eggplant, Pumpkin) to determine the success wrapping rate. Each fruit-vegetable is divided into two grades such as A grade and B grade. B grade is more bended curve than A grade. The success wrapping rate of eggplant was 100% regardless of the grade and the number of fruit-vegetable. and also that of cucumber was 100% all but packing 4 numbers of B grade. However, that of pumpkin was 45%, As the number and the bended degree of pumpkin was increased, the success wrapping rate of pumpkin was decreased, because the surface area or the bended degree were increased.

This study aims to provide basic data for planning the supply and demand of urban parks and setting up facilities in urban parks that reflect the use patterns of visitors. The study was conducted by surveying the total number of urban park users and the number of users for different time zones and analyzing their use patterns through on-site surveys at 17 urban parks located in seven cities/counties in Gyeonggi province. The result showed that as for distribution of urban park users by time zone, the number of users was highest in the afternoon. Between 7 and 9 o'clock in the morning in weekdays, many users came to urban parks for their morning exercises. There was hardly no difference between male and female. When the number of users of 17 urban parks was surveyed, a park was used by 734 people per day on weekdays in average. When the total number of users per year was estimated, a resident nearby a park visited the place 4.7 times a year in average. In addition, the analysis showed that the number of users of man-made parks was twice as high as that of natural parks. The number of users did not vary depending on the size of a park. As for use patterns by time zone, no difference was found in activity types between parks larger than 100,000 $m^2$ and those less than 100,000 $m^2$. Usually, in the morning, users came for exercises In the afternoon, users visited the parks for more diverse purposes. In the evening, they tended to visit parks to work out and wrap up a day. Going forward, the outcome of this study should be utilized as important data for analyzing the demand and supply of urban parks. In addition, the number of users by time zone and their use patterns should be fully considered when introducing facilities in parks.
Upper limb nerve damage is a common condition, and evidence suggests that functional recovery may be limited following peripheral nerve repair in cases of delayed reconstruction or reconstruction of long nerve defects. A 26-year-old man presented with traumatic injury from a wide, blunt wound of the right forearm caused by broken glass, with soft tissue loss, complete transection of the radial and ulnar arteries, and a large median nerve gap. The patient underwent debridement and subsequent surgery with a microsurgical free radial fasciocutaneous flap to provide a direct blood supply to the hand; the cephalic vein within the flap was employed as a venous vascularized chamber to wrap the sural nerve graft and to repair the wide gap (14 cm) in the median nerve. During the postoperative period, the patient followed an intensive rehabilitation program and was monitored for functional performance over 5 years of follow-up. Our assessment demonstrated skin tropism and sufficient muscle power to act against strong resistance (M5) in the muscles previously affected by paralysis, as well as a good localization of stimuli in the median nerve region and an imperfect recovery of two-point discrimination (S3+). We propose a novel and efficient procedure to repair >10-cm peripheral nerve gap injuries related to upper limb trauma.

Objectives : This study was aimed to find significant prognostic factor of inpatients with severe atopic dermatitis (AD) who treated in a Traditional Korean Medicine (TKM) hospital. Methods : A retrospective review of medical records of 39 patients with severe AD who hospitalized for more than 7days was performed. All patients were treated with acupuncture, herbal decoction and herbal wet wrap dressing. Therapeutic effect was assessed by difference of objective SCORing of Atopic Dermatitis index (${\Delta}OSI$) at admission and at discharge. Patients were divided into two groups: improvement group (${\Delta}OSI{\leq}5$) and no-improvement group (${\Delta}OSI>5$), and clinical characteristics, severity, infectious complication, serum total IgE, eosinophil counts, adherence and concomitant treatment were investigated. Results : There were 7 cases in no-improvement group. There was no significant difference in OSI or infectious complication between the two groups. Also, there was no significant difference in total serum IgE and eosinophil counts, which are known to be related to severity of AD. However, the proportion of adherence group was significantly lower in no-improvement group than improvement group. Conclusions : This study suggest that treatment adherence is a significant prognostic factor for treatment outcome in inpatients with severe atopic dermatitis. If the adherence to treatment is improved, the therapeutic effect of hospitalization would increase in spite of severe AD or infectious complication.
In this study, a post-fire safe shutdown analysis (PFSSA) including multiple spurious operation (MSO) treatments for cables was conducted with an imaginary nuclear power plant for training using a deterministic fire analysis code. The imaginary nuclear power plant for the training consisted of a reactor containment building and an auxiliary building, including a total of 22 fire areas. The equipment including valves, pumps, emergency diesel generators, switch gears, motor control centers, and logic controllers were located in each fire area of the imaginary plant. It was assumed that each equipment is connected with two cables and that each cable passes through the fire areas along the cable trays. A database containing the information on the equipment and cables for the imaginary plant was constructed for the fire area analysis. The fire area analysis was performed for several assumed MSO scenarios, equipment logics, and cable logics. A mitigation measure using a three hour rated wrap was applied to the failed cables and cable trays after the fire area analysis.

This paper is concerned with the long-term performance of geo-textile (GT) composites in terms of creep deformation and frictional properties. Composites of PVA GT and HDPE GM were made to investigate the advanced properties of long-term performance related to waste landfill applications. The same experiments were also performed for typical polypropylene and polyester GT and compared to PVA GT/HDPE GM composites. We also develop high performance GT composites with GM by using PVA GT, which is capable of improving the frictional properties and thus enhances long-term performance of GT composites. Experimental study reveals that the friction coefficient of GT composites is relatively large compared with those of polyester and polypropylene non-woven GT as long as the friction media has similar size to the particles of domestic standard earth. In addition, the geo-composites bonded with geo-grid by a chemical process were investigated experimentally in terms of strain evaluation and creep response values. Geo-grid plays an important role as a reinforcing material. Three kinds of geo-grid were prepared as strong yarn polyester and they were woven type, non-woven type, and wrap knitted type. The sample geo-grids were then coated with PVC. The rib tensile strength tests were conducted to evaluate geo-grid products in terms of tensile strength with regard to single rib. The test was performed according to GRI-GGI. It was concluded again from the experiments that the tensile and creep strains of the geo-grid showed such stable values that the geo-grid prepared in this study could protect geo-textile partially in practical structures.
High quality and expedient processing repair methods are necessary to enhance the service life of bridge structures. Deterioration of concrete can occur as a result of structural cracks, corrosion of reinforcement, and freeze.thaw cycles. Cost effective methods with potential for field implementation are necessary to address the issue of the vulnerability of bridge structures and how to repair them. Most infrastructure related applications of fiber-reinforced plastics (FRPs) use traditional hand lay-up technology. The hand lay-up is tedious, labor-intensive and relies upon personnel skill level. An alternative to traditional hand lay-up of FRP for infrastructure applications is Vacuum Assisted Resin Transfer Molding (VARTM). VARTM uses single sided molding technology to infuse resin over fabrics wrapping large structures, such as bridge girders and columns. There is no work currently available in understanding the interface developed, when VARTM processing is adopted to wrap fibers such as carbon and/or glass over concrete structures. This paper investigates the interface formed by carbon fiber processed on to a concrete surface using the VARTM technique. Various surface treatments, including sandblasting, were performed to study the pull-off tensile test to find a potential prepared surface. A single-lap shear test was used to study the bond strength of CFRP fabric/epoxy composite adhered to concrete. Carbon fiber wraps incorporating Sikadur HEX 103C and low viscosity epoxy resin Sikadur 300 were considered in VARTM processing of concrete specimens.
Many varieties in folk costumes have inspired fashion designs for a long time. Each country, with a unique style of its own reflects their own traditions, beliefs, customs and morals into their traditional costumes. The traditional methods of creating different ways of drapery methods by using only a rectangular piece of cloth have been passed down from generation to generation and it is still used today. This way of styling has been developed mainly in the Middle East, Asia and Africa and the modifiable ways of creating drapery wearing methods are as follows. The first modifiable styling method is changing the purpose of wearing costumes according to the needs and the wants of the person who wears it. The second method is exposing the knots on the surface of the garments and by doing this, there was no visible difference on the aesthetic formation and it did not alternate for a long time. This means that simple knot shapes have been used to tie edges of rectangular fabrics. The third method is a wrapping type of modifiable styling method, which has been used most commonly in folk costumes because there are lots of ways to wrap a rectangular cloth around the body. The fourth way is the fixed type of modifiable styling method and this method can only be noticed only in the Moroccan Izar using fibulas and belts to alter the shape of the Izar. The fifth method is the composite type of modifiable styling method. This method starts by cutting out cylindrical shapes of fabrics and then wraps or twists it to fit the body. The most significant character of modifiable styling methods in folk costumes is to use rectangular cloths, which varies only in ratio of length, width and sizes. Therefore, this study suggests that rectangular cloths can create enormous amounts of fashion styling which can be easily adapted and created in everyday fashion life.
With these excavated clothes discussed above, the clothing style before and after the Chosun-Japan War from 1592 to 1597 can be summarized as follows. 1) Shroud was a clothes newly made for funeral or usually worn by the deceased. Shroud was mostly a unlined clothes whose adjustment was made in such way its left part was on top of its right one. Yeomeui, a clothes used to wrap up the body of the deceased or fill between the body and the coffin, was usually lined or quilted. Suryeeui was a suit sent by close relatives of the deceased or granted by the court. Mostly padded with cotton or quilted, suryeeui was used only for yeomeui. 2) The term of ching was used to count units of po and suits of trousers and jeogori during dressing the deceased for burial. If trousers and jeogori were not joined into a suit, they were not counted as ching. 3) Aekjueumpo, bangryeongsangeui, three-forked trousers and haengjeon for women were all clothes worn around the war. All these clothes were not worn after the war. 4) Several types of po which were discovered in Daejeon included danryeong, simeui, nansam, jikryeong, cheolik, aekjuempo, changeui and jungchimak for men and jangeui for women. Often, jikryeong, cheolrik, aekjueumpo and bangryeongsangeui were used before the war and changeui and jungchimak since then. 5) The git of jeogori had the style of mokpan git before the war, which was changed into that of dangko git through making the rectangular ege of mokpan git rounded in the 17th century. And jeogori became entirely small sized and the baerae line of sleeve became oblique. 6) In funeral rites of Daejon, simeui and nansam both of which were symbols of Confucian scholars, instead of official uniforms, were used as funeral garments. This suggests that funeral rites of Daejeon considerably reflected academic traditions of the Giho school meaning groups of scholars representing the region.
