The main purpose of this study is to investigate the suitability of Boesun (the Korean Socks) to the foot. In order to find the problem of Boesun, I made up the questionnaire. The suitabltity of Boesun to the foot was experimented by 'the replica method', 'the fuse method' and 'the deform painting method'. The pressure of Boesun to the foot was measured by utilizing a human sensitivity as a sensor. The results were as follows. 1. In the questionnaire, the fore part of Boesum was uncomfortable by the pressure. 2. The surface area of Boesun was generally smaller than the surface area of the foot, but the ratio of two surface area related closely to the individual. 3. At the cross-sections from No. 1 to No. 10, the breadth of the worn Boesun was smaller than the breadth of the foot. Because of the smaller breadth of the worn Boesun, the foot was get the pressure at the fore part of Boesun. This result accorded with the result of the questionnaire. 4. The location of the deformation by 'deform painting method' was almost the fore part of Boesun. 5. The pressure of Kwon's Boesun was 2.57$\~$2.99kg, the pressure of Kim's Boesun was 1.31$\~$1.74 kg and the pressure of Lee's Boesun was 3.42$\~$3.88kg. Compared with the distribution chart of the pressure, Kwon's Boesun was involved the back part of 'slightly pressured' and the fore part of 'pressured', Kim's Boesun was involved the fore part of 'slightly pressured' and Lee's Boesun was involved the middle part of 'pressured'.

The purpose of this study is to identify the fragmented points of mountain ranges in Daegu metropolitan city using New Sangyeongpyo (Chart of Mountain Ranges), road system map and GIS spatial analysis, and to prioritize the identified fragmented points for restoration based on quantitative assessment. Moreover, this study proposes restoration plans reflecting the assessment results and characteristics of each fragmented point. The results of this study are summarized as follows: First of all, analysis of the distribution of mountain ranges in Daegu metropolitan city showed that jimaek and semaek in Daegu account for 2% of all mountain ranges in the country, implying that the mountain ranges of Daegu do not hold significant ranking on a national level. However, it was found that numerous fragmented points are appearing due to roads. According to the analysis, 35 fragmented points were identified, of which 15 were found to be restorable. In terms of restoration potential and involved risks, assessment results of the 15 fragmented points indicated that 6 points are at Grade I, 3 points are at Grade II and 6 points are at Grade III. Therefore, a methodology of restoring fragmented mountain ranges was proposed through three suggestions of restoration plans that consider the characteristics of each fragmented points. The results of this study are expected to be highly useful as basic data for effective restoration of mountain ranges in connection with mountain range restorations and relevant projects implemented on a national level in the future.

Background: The incidence of rectal cancer is increasing in younger age groups. Limited data is available regarding survival outcome in younger patients with conflicting results from western world. The goal of this study was to determine survival in patients with rectal cancer <30 years of age and compare it with their older counterparts in the Pakistani population. Materials and Methods: A retrospective chart review of patients operated for rectal adenocarcinoma between January 2005 and December 2010 was performed. Patients were divided into two groups, Group 1 aged ${\leq}30years$ and Group 2 aged >30years. Patient characteristics, surgical procedure, histopathological details and number of loco-regional and distant failures were compared. Expected 5 year survival was calculated using Kaplan Meier curves and significance was determined using the Log rank test. Results: There were 38 patients in group 1 and 144 in group 2. A significantly high number of younger patients presented with poorly differentiated histology (44.7% vs 9.7%) (p=0.0001) and advanced pathological stage (63.1% vs 38.1%) (p=0.04). Predicted overall 5 year survival was 38% versus 57% in groups I and II, respectively (p=0.05). Disease free survival was 37% versus 52% and was significantly different (p=0.007). Conclusions: Early onset rectal cancer is associated with poor pathological features and a worse outcome in Pakistani population.

Objectives The purpose of this study is to investigate Korean clinical studies on treatment of childhood obesity and to propose for better treatment options for childhood obesity. Methods Based on RISS, KISS, OASIS, KMbase with the keyword 'childhood obesity', 'child obesity', 'obese child', 'overweight child', total of 21 randomized controlled trials (RCTs), 11 single clinical studies, 3 chart reviews and 3 case reports have been found, and were analyzed. Results and Conclusion 1. Some study subjects were classified based on their sex - only men or women in a group or sometimes both. Another way of classify the study subjects were based on their age - preschooler, primary school students, middle school students, and high school students. The diagnostic criteria of the subjects were BMI (body mass index), Body fat percentage, Obesity index, Weight and unknown criteria. 2. The treatments used in 38 studies were exercise alone, education alone, both exercise and education or herbal therapy. The 7 studies that used herbal therapy as part of their study intervention had a study group with herbal intervention only and the other 2 study group with herbal treatment in addition to exercise and education. 3. 9 studies included herb medicines, electroacupuncture, auricular acupuncture, cupping, aroma massage, infrared light, and abdomen pad. Herb medications used in 5 studies included Chegameuiin-tang 2 kinds, Sobieum, Biman-tnag, and I-razin. 4. The methods of assessment used in 38 studies were classified by 7 categories and anthropometry parameters which is the basic methods are used in all studies 5. Almost studies (29 studies in all 38 studies) were using anthropometric parameters results on significantly effectiveness of childhood obesity. 6. More studies are needed to prove true effectives from various treatments, especially herbal therapy for childhood obesity.

For the color offset printing, it starts with input of data. The past days, drum scanner or flat scanner used to input of data, but now it changes gradually into using of digital camera because digital camera become popular. The high quality digital camera saves as a data(RAW format), sRGB which have built in digital camera, or Adobe RGB format. sRGB of ICC(International Color Consortium) profile is a standard color gamut of digital camera. Distribution of color gamut in sRGB is less than Adobe RGB have a distribution in ICC profile. sRGB also can not be expressed in some specific part, because distribution of color gamut in sRGB is not able to cover all parts in ICC Profile of international standards CMYK. It is more popular to use Adobe RGB than sRGB to do high quality offset printing and software basis color setting in Europe and Japan. In spite of this data basis, there is a difficulty of doing color correction between the color proofing prints and the final prints. To see how the software color setting effects to RGB data, this thesis will use Gretag Macbeth ColorChecker 24 patch which has the most general natural color chart to compare sRGB and Adobe RGB to check the differences of color changes. It will use the several factors that came out from the process of making ICC Profile to figure out the optimum In-house profile. It also compares the differences of using matt paper and glossy paper to do best quality color proof offset printing, and how the Rendering Intent effects the proof print.

The aim of this paper was to propose a new method of bimaxillary orthognathic surgery planning and model surgery based on the concept of 6 degrees of freedom (DOF). A 22-year-old man with Class III malocclusion was referred to our clinic with complaints of facial deformity and chewing difficulty. To correct a prognathic mandible, facial asymmetry, flat occlusal plane angle, labioversion of the maxillary central incisors, and concavity of the facial profile, bimaxillary orthognathic surgery was planned. After preoperative orthodontic treatment, surgical planning based on the concept of 6 DOF was performed on a surgical treatment objective drawing, and a Jeon's model surgery chart (JMSC) was prepared. Model surgery was performed with Jeon's orthognathic surgery simulator (JOSS) using the JMSC, and an interim wafer was fabricated. Le Fort I osteotomy, bilateral sagittal split ramus osteotomy, and malar augmentation were performed. The patient received lateral cephalometric and posteroanterior cephalometric analysis in postretention for 1 year. The follow-up results were determined to be satisfactory, and skeletal relapse did not occur after 1.5 years of surgery. When maxillary and mandibular models are considered as rigid bodies, and their state of motion is described in a quantitative manner based on 6 DOF, sharing of exact information on locational movement in 3-dimensional space is possible. The use of JMSC and JOSS will actualize accurate communication and performance of model surgery among clinicians based on objective measurements.

In the city of Asia like Seoul and Tokyo, aggregate power is poured into the city making which is suitable in new age. Large-scale re-development is active in various places as the present condition, As for the various East Asian cities, high-level utilization conversion of the land and high conversion of the building are advanced. As for these realities, the re-development is advanced in the situation that has not been clarified enough though it is true that green of the city has decreased. This research was aimed at the clarifying the allocation of greenery when proceeding with town planning projects by quantifying the possibility of allocating greenery in the form of rooftop landscaping in redeveloped areas. Moreover, the distribution of the green in the re-development region was calculated and the coexistence level of green space was calculated, The realities of a desirable green were clarified in the spectacle by understanding a sight and spatial continuousness in the green. In order to clarify the potentiality of roof greenery revaluating, the research was conducted by analyzing from aerial photographs, in Tokyo and Seoul, And the flow of the research was conducted by selection of research object area, taking pictures, acquisition of the aerial photography, rearrangement the data and the analysis. As a result, I was able to prepare a land vegetation coverage classification chart and obtain data pertaining to the level of urban and green tract of land for the researched cities of Tokyo and Seoul. By analyzing this data, we were able to indicate patterns of greenery unable to be obtained through data from ratio of vegetation coverage and ascertain the effectiveness of rooftop landscaping.
