Intercostal neuralgia is neuropathic pain that develops in the thorax and abdomen. It usually occurs as a result of injury or inflammation associated with the intercostal nerve triggered by trauma, surgery, or herpes zoster. Primary intercostal neuroma is a rare cause of intercostal neuralgia. A 69-year-old male patient without a history of thoracic trauma or surgery underwent repeated testing and intermittent treatment for refractory pain in the right chest and abdomen for several years. However, the treatment had limited effect. Abdominal computed tomography performed to diagnose recent pain aggravation revealed schwannoma of the 11th intercostal nerve. The patient’s pain was relieved following surgical excision of the tumor.

Pyramid type three roll bending machines are widely used in roll-bending process to produce singly curved plate. In forming singly curved plate, controlling the vertical displacement of the center roller is most important to acquire the shape required and automation system of the process. In this paper roller bending process is modeled as an elastic-plastic phenomenon and analyzed using beam theory and finite element method. In finite element analysis the workpiece is modeled by using beam elements and plane strain elements respectively. Through the analyses vertical center roller displacement is obtained to get constant curvature distribution along arc length. The relationship between center roller displacement and curvature in steady state as well as residual stress and strain along plate thickness direction are calculated through finite element analysis.

In the 21st century, we will face strong market forces by Commerce At Light Speed/Electronic Commerce (CALS/EC) and mounting competition. Corporations can no longer manager along historical tracks. Companies are discovering that old solutions do not work with news problems. The industry parameters have changed, and so have the risk with CALS. The shoes manufacturing industry (SMI) has the same problems as the other industries. In order to change SMI to the knowledge-based industry with CALS, this paper proposes a conceptual design for CALS of SMI, which includes the goal, system structure, function design of subsystems and the required infrastructure.

The survey site, the Hyundai Apartment Complex in the Bundang Model Complex, includes three housing layout types; super high-rise, high-rise and low-rise apartment buildings. The site includes artificial ground over underground parking lots. The overall objective of this study is to evaluate social and physical factors of housing environments in each types of layout. The data has been complied from residents of apartment through questionnaire. The questionnaire include elements of neighborhood, outdoor space, parking zones, and the overall complex design in each layout types. The predictors of outdoor space satisfaction in apartment housing complex are found as follows: "abundance of trees in quantity", "the role as front yards", "harmony of buildings with landscape", "the more distance between buildings" and "maintenance quality of site". Layout of super high-rise apartment site is most satisfied. Introduction of car-free deck space is favored by resident because of safty and quiet resting area. However the low quality of green and lack of shades on the artificial land are identified as problems.on the artificial land are identified as problems.

Landscaping on artificial ground is currently served as a means to imposing a greenery benefit on high-density and high-rise apartment sites. It functions as a sub-hierarchy in apartment planning such as ornamental element from the past. Major parking space tends to be allocated on the basement area in response to the required parking regulation. Therefore, competitive relatioinship between the parking and greenery space I limited outdoor of apartments leads to the development planning strategy and technology of artificial ground. This study aims at evaluating landscape planning on artificial ground of apartment complex through several approaches such as site survey, plan drawing analysis, and interview with related field experts. 15 survey apartment sites including Bundang Model, Shindaebang-dong, Pyoungchon Hyundai Apartments have been selected for conducting the research. Main results of this study are summarized below : First, scattering allocation of artificial ground between apartment building units is a dominant plan layout type among the survey sites. Even though unifying allocation type has an advantage to maximize underground parking space, it has a difficulty in maintaining proper soil ground base for nurturing plants. Therefore, underground parking space should be planned by unifying allocation type placed separately from apartment units. This plan type can provide a balanced planting between soil and artificial ground on surface level. Second, It is strongly recommended to integrate the whole planting base which involves architectural structure, drainage, and water proofing above the planting design. When considering that process as a professional subject dealing with natural material such as trees and shrubs, those tasks should be directed by landscape architectural divison and landscape architect. And planting area for artificial ground has to be specified in initial phase of architectural design. This step provides an opportunity to make a proper decision on structural load, drainage, and water proof design as an integrated part of the management.

Background: Postoperative nausea and vomiting (PONV) are common complications after general anesthesia. This study compared the effects of palonosetron and ondansetron in preventing PONV in patients undergoing thyroidectomy. Methods: 100 non-smoking female subjects were randomly assigned to a palonosetron group (n = 50) or an ondansetron group (n = 50). The patients of each group received 0.075 mg of palonosetron or 8 mg of ondansetron through intravenous bolus injection before induction of general anesthesia. The incidence of nausea and vomiting were monitored at 2 h, 24 h and 48 h after operation. Results: The incidence of PONV during 48 h after operation had no significant differences between the groups. However, the incidence of nausea was lower in the palonosetron group than in the ondansetron group (34% vs. 56%, P = 0.027). No differences were observed in incidences of vomiting, use of antiemetics and adverse events between the groups. Conclusions: Palonosetron was more effective than ondansetron in preventing nausea for patients undergoing thyroidectomy. However,the effect of palonosetron or ondansetron in preventing PONV was similar.

It depends on the joint configuration, dimensions and constraints of the joint whether the residual stress at the root of single-sided butt weld is tensile or not. Therefore, recommendation is generally made that high R ratio should be used in the fatigue test of welded joint in order to prevent excessively long life caused by compressive residual stress. In this research, the residual stress profile in butt weld joint was obtained through compliance method, using successive extension of a slot and measurement of the variation of strain during the slot extension. The residual stress profile was firstly assumed to be the linear summation of Legendre polynomials up to 9th order excluding 0th and 1st order. Strain variation on the surface was measured while the slot was being extended by cutting to find out the 8 unknown coefficients of each polynomial term. The cut was made by the electric discharge machine. It was concluded that the residual stress near the surface is positive valued, however, it turned into the negative value as soon as it passed through 2 or 3 mm of the depth.

The POE (Post Occupancy Evaluation) was carried out to provide basic behavioral knowledge for its planning and management of the Rose garden at Yong-In Farmland. Through its users a total of 1545 questionnaire were completed. They were designed by four sets of variables, such as behavoir pattern, motivation for visting, post-use evaluation, and users demographic variables. The findings are as follows: Firstly, descriptive statistics were employed to analyze behavoir pattems and users' demographic varialbes. As a result, 86% of visitors lived in Kyoung-Ki Do and Seoul : most of the vistiors is in their twenties and thirties : most of visitors were accompanied by their families, relatives and lovers : 66% of vistiors came by cars to Yong-In Farmland : 47% of visitors stayed for 1-2 hours in average. Secondly, factor analysis was used in order to group satisfaction factors. Five factors are : 'manegement of the garden', 'rose appearance', 'design and aesthetics', 'lighting and sound', and 'theme display'. Thirdly, regression analysis was used to examine the sources of satisfaction. The results of regression analysis shows that 42% of total variances was explained by ten variables. The most effective variable is 'the aspect of rose condition and appearance'. The overall evaluation for the new rose garden was 'satisfied' though the level of the 'satisfied' varies according to their ages. Twenties and thirties prefer that image of fantastic European style which was frequently showed on T.V or movies. Forties and fifties like more abudant scenery of roses of an Europenan style garden but unsatisfied with shortage of roses.
