This study analyzed the system and arguments on the light-pink official uniforms and investigated the backgrounds and principles on the changes of the Sibok system. A study on light-pink danryeong in the latter part of the Joseon Dynasty is a de facto study on Sibok since the name of the light-pink official uniforms (implemented at the time of King Seonjo) changed from Sangbok to Sibok. Sangbok is discussed to explain the name change from Sangbok to Sibok and distinguish their usages; in addition, Gongbok is examined to understand the characteristics of the Sibok system. The Annals of the Joseon Dynasty (books written by scholars) and related laws are used as research materials. The research results are as follows. The name of the light-pink uniforms (a custom before the Japanese invasion in 1592) changed from Sangbok to Sibok at the time of King Gwanghaegun and the light-pink uniform was used as a relatively light formal uniform compared to Sangbok. Sibok was added to the law Sok-dae-jeon at the time of King Yeongjo (because the king respected the custom) and its color rank system was denoted from light-pink and red. Sibok was revised to light-pink, blue, and green under the law Dae-jeon-tong-pyeon that was promulgated at time of King Jeongjo. In the development of the Sibok system in the latter part of the Joseon Dynasty, the color rank system of Gongbok was reflected. The sovereign ideas in the official uniforms in the latter part of the Joseon Dynasty (revealed in the study of the system and arguments on the light-pink official uniforms) were the thoughts that respected the custom and the principles that distinguish ranks to establish a Confucian based hierarchy.

The accuracy of master cast reproduction by a polyvinylsiloxane impression material using two visible-light curing resin and autopolymerizing polymethyl methacrylate resin custom tray material was investigated. Custom trays were fabricated from a master cast that had three index points marked on both inner and outer vestibules and then poured in yellow stone. The distance between the reproduced index points were measured to be ${\pm}0.001mm$ with a measuring microscope and the algebraic norms calculated for each tray material. No differences were found in the algebraic norms of inner and outer dimensions for upper tray impressions by ANOVA(p>0.05). However, T-test revealed that there were differences between upper and lower impressions and Tukey's hsd test revealed that in lower tray impressions, the Palatray in inner, the Lightplast in outer dimensions respectively were different from other materials. The index points reproduced on the casts compared with the master cast, were closer together for upper tray impressions. All four tray materials produced acceptable casts, 1. Algebraic norms of inner and outer dimensions of the test casts for upper trays were not statistically different irrespective of materials.(P>0.05) 2. T-test showed that there were differences between means with upper and lower trays especially in outer dimension.(P>0.05) 3. But, algebraic norms of inner and outer dimensions of the test casts for lower trays were statistically different between materials. 4. Palatray XL in inner, Lightplast-platten in outer dimensions respectively for lower trays were different from other materials, but, the nearest to the original model.

In this paper, design of small microprocessor unit is implemented using research purpose VHDL and CAD tools by top-down design method. For this, original basic MPU and its pipelining architectures are suggested. Once, design target, instruction sets, architecture are decided, the operation is confirmed by C language simulation, and then the operation is confirmed by checking internal register contents for given inputs in the case of VHDL simulation. Then, design layouts are made by full/semi-custom design methods by research CAD tools and related simulation is implemented. The feasibility of suggested pipelined structure for performance improvement is confirmed by simulation, and related problems and future research directions are discussed. In conclusion, the MPU design methodology is set up and the design change of architecture is possible by this paper.

PURPOSE. This study examined the effects of the abutment types and dynamic loading on the stability of implant prostheses with three types of implant abutments prepared using different fabrication methods by measuring removal torque both before and after dynamic loading. MATERIALS AND METHODS. Three groups of abutments were produced using different types of fabrication methods; stock abutment, gold cast abutment, and CAD/CAM custom abutment. A customized jig was fabricated to apply the load at $30^{\circ}$ to the long axis. The implant fixtures were fixed to the jig, and connected to the abutments with a 30 Ncm tightening torque. A sine curved dynamic load was applied for $10^5$ cycles between 25 and 250 N at 14 Hz. Removal torque before loading and after loading were evaluated. The SPSS was used for statistical analysis of the results. A Kruskal-Wallis test was performed to compare screw loosening between the abutment systems. A Wilcoxon signed-rank test was performed to compare screw loosening between before and after loading in each group (${\alpha}$=0.05). RESULTS. Removal torque value before loading and after loading was the highest in stock abutment, which was then followed by gold cast abutment and CAD/CAM custom abutment, but there were no significant differences. CONCLUSION. The abutment types did not have a significant influence on short term screw loosening. On the other hand, after $10^5$ cycles dynamic loading, CAD/CAM custom abutment affected the initial screw loosening, but stock abutment and gold cast abutment did not.

Because of the ever-increasing software complexity, model-based development techniques are becoming an essential technique in software development. However, even if model-based techniques are used, the test case generation for complex software is still a challenge to solve. In this paper, we propose a method to generate automatic test cases based on UML model using custom parser and SMT solver. By proposed technique, a test case can be generated even though the model is described in a platform independent language such as action language, or in a platform dependent language. In addition, a concolic execution technique is applied to efficiently generate test cases in the model. In this paper, we present a case study on the power window switch model of Hyundai Santa Fe through the proposed test case generation technique.

Background : Klippel-Trenaunay-Weber syndrome (KTS) is a rare congenital medical condition characterized by complex vascular malformation. KTS consists of a classic triad of capillary malformation (hemangioma), venous malformations and bone or soft tissue hypertrophy causing limb asymmetry. The aim of this report is to describe management for gait disturbance and foot pain in a Patient with KTS using custom-made total contact insole. Case presentation : A 32-year-old man with KTS presented with a 3-year history of gait disturbance on hard surface due to right first toe pain and Achilles tendon tightness. The patient had soft tissue hypertrophy, varicose veins and port-wine stains over the right lower limb associated with KTS. True leg length discrepancy was 2 cm. We prescribed custom-made total contact insole to protect his deformed foot and correct leg length discrepancy. The insole of right side included wedge shaped heel lift and the insole of left side included full length lift to add extra support on unaffected side. Also, we provided compression stocking and physiotherapy including manual lymphatic drainage for lymphedema and stretching exercise for tightness in right lower extremity. At 3 years follow-up, postural alignment including pelvic obliquity was improved using a custom-made total contact insole. The degree of scoliosis and foot pain were also reduced. Conclusion : An individualized and multidisciplinary approach is essential regarding the complexity of comorbidities in patients with KTS. For patients with KTS, orthotic management should be considered to prevent and correct deformities related to KTS. Active orthotic management, compression stocking and physiotherapy can enhance the quality of life and function in patients.

This study aimed to develop a a custom-made dress form for draping using a live model's 3D body scan obtained from an entry-level 3D handheld scanners, 3D modeling software and 3D printing technology. A female subject was recruited whose body size fell under the normal (N) body shape criteria suggested by KS K 0051. First, the handheld scanner reduced the length of the legs in scanning, but most of the scanning operations between the neck and crotch levels were conducted accurately. Therefore, this study was designed to develop a torso dress form. The full body 3D scan was edited into a torso shape using ZBrush® software. Using Rhinoceros^® and Materialise's Magics software, a 3D body scan was modeled so that the user could fit two types of mannequin stands (one with a neck fixation from above and one with an insert from below) to the dress form. The body scan was divided into 9 pieces to fit the printable size of the Stratasys 3D printer Fortus 250mc, and the cross-sectional distance from the center to the periphery was downsized by 2 mm. After outputting the dress form scan file with a 3D printer, the dress form was manufactured by the first covering it with a 4 oz nonwoven pad and the second covering with a single jersey material.

Recently, remote controls for home appliances have been produced as many as the number of home appliances per household, and new home appliances are being released, but the number of new remote controls is continuously increasing due to their separate functions. Therefore, it is not inconvenient for first time users to use many remote controls because it is difficult and bulky. In recent years, the practical use of a universal remote control, such as large companies such as SAMSUNG and LG are producing a variety of forms. In this paper, we explain how to transmit and receive data format and infrared remote control through custom code identification method used in IR remote control for each company, and to see the size, characteristics and difference with ordinary remote control through ATmega128 remote control experiment. The ATmega128 can be used to control various home appliances displayed on the LCD. As a result, it can be seen that the number of remote controllers having only each function is reduced, and the integrated remote controller using ATmega128 Can handle household appliances.

Background: After the resection at the mandibular site involving oral cancer, free vascularized fibular graft, a type of vascularized autograft, is often used for the mandibular reconstruction. Titanium mesh (T-mesh) and particulate cancellous bone and marrow (PCBM), however, a type of non-vascularized autograft, can also be used for the reconstruction. With the T-mesh applied even in the chin and angle areas, an aesthetic contour with adequate strength and stable fixation can be achieved, and the pores of the mesh will allow the rapid revascularization of the bone graft site. Especially, this technique does not require microvascular training; as such, the surgery time can be shortened. This advantage allows older patients to undergo the reconstructive surgery. Case presentation: Reported in this article are two cases of mandibular reconstruction using the ready-made type and custom-made type T-mesh, respectively, after mandibular resection. We had operated double blind peer-review process. A 79-year-old female patient visited the authors' clinic with gingival swelling and pain on the left mandibular region. After wide excision and segmental mandibulectomy, a pectoralis major myocutaneous flap was used to cover the intraoral defect. Fourteen months postoperatively, reconstruction using a ready-made type T-mesh (Striker-Leibinger, Freibrug, Germany) and iliac PCBM was done to repair the mandible left body defect. Another 62-year-old female patient visited the authors' clinic with pain on the right mandibular region. After wide excision and segmental mandibulectomy on the mandibular squamous cell carcinoma (SCC), reconstruction was done with a reconstruction plate and a right fibula free flap. Sixteen months postoperatively, reconstruction using a custom-made type T-mesh and iliac PCBM was done to repair the mandibular defect after the failure of the fibula free flap. The CAD-CAM T-mesh was made prior to the operation. Conclusions: In both cases, sufficient new-bone formation was observed in terms of volume and strength. In the CAD-CAM custom-made type T-mesh case, especially, it was much easier to fix screws onto the adjacent mandible, and after the removal of the mesh, the appearance of both patients improved, and the neo-mandibular body showed adequate bony volume for implant or prosthetic restoration.

This study looks at the origin of a wild-ginseng, Korean ginseng, and traces the origin of associated wild-ginseng digging customs back to the Annals of the Joseon Dynasty. These historical customs helped Korea gain control over its wild ginseng resources following Japanese colonization acts, Korea's present-day forest laws, and Korean Civil Law. Prior to Japanese colonial rule in Korea (1910-1945), ginseng digging was a common custom, but Imperial Japan distorted Korea's own legal principles of the public rights of wild-ginseng digging during this colonial period. Distorted legal principles concerning digging customs continued after Korea's liberation from Japanese rule and were maintained until the enforcement of the Korean Civil Law in 1960, when legal principles of the right of common were changed to special servitude. The origin of the right of common can be found in the Sichojang of the Joseon Dynasty. The Sichojang, a place where local residents jointly collected firewood and fed livestock, was the minimum right to life and interest at the time. Since the right of common was the right to life, Imperial Japan attempted to abolish it, but it was never successful. In addition, distorted legal principles have been maintained in present-day forestry-related laws and regulations. Over 75 years since the liberation from Japanese rule in 1945, it is imperative to break away from the distorted legal principles and acknowledge that digging custom rights have changed from common customs to a special servitude under Korean Civil Law. Hence, an organization of wild-ginseng diggers is an unincorporated association, and their wild-ginseng digging customs can be constituted as a special servitude. Hence, their practices should be considered valid under customary law. Through this, it will be possible to clarify the legal nature and grounds for ginseng-related wild-ginseng digging activities, as well as the civil responsibility for the activities of wild-ginseng diggers.
