On this study, realtime GPS technique and combination of GPS/GLONASS technique are used to extracting coastline. Th￡ object of coastline is Gwanganri beach located in Busan. The coastline is observed along the traces of coastline when high wave of scar by using digital map of 1:1,000 and at random time zone, coastline is surveyed along the boundary line that is contacting with sea water level. When the coastline of random time zone is converted by height of tide table, the coastline when high wave of scar and converted coastline are shown as coincident approximately.

On this study, it was applied that the method of Coastline extracting by aerial photogrammetry so as to extract the coastline using the method of RTK GPS/GLONASS. The observed area is Gwanganri beach that is located in Pusan and it was observed according to high wave of scar when the approximate highest high water and it was surveyed according to that the boundary line connecting to sea water surface at random time-zone. Observation analysis was used digital map of 1:1,000 and compared coastline that was converted tide with coastline of high tide. So this conclusions was agreed with converted coastline and high tide coastline.

Background Major problems with cervicoplasty by direct skin excision include the subjective nature of skin markings preoperatively and the confusing array of procedures offered. This technique incorporates curved incisions, resulting in a wave-like scar, which is why the procedure is called a "wave-plasty". Methods This prospective study includes 37 patients who underwent wave-plasty procedures from 2004 to 2015. Skin pinching technique was used to mark the anterior neck preoperatively in a reproducible fashion. Intra-operatively, redundant skin was excised, along with excess fat when necessary, and closed to form a wave-shaped scar. Patients were asked to follow up at 1 week, 6 weeks, and 6 months after surgery. Results The mean operation time was 70.8 minutes. The majority (81.3%) was satisfied with their progress. On a scale of 1 to 10 (1 being the worst, and 10 being the best), the scars were objectively graded on average 5.5 when viewed from the front and 7.3 when seen from the side 6 months after surgery. Complications consisted of one partial wound dehiscence (2.3%), one incidence of hypertrophic scarring (2.3%), and two cases of under-resection requiring revision (5.4%). Conclusions In select patients, surgical rejuvenation of the neck may be obtained through wave-like incisions to remove redundant cervical skin when other options are not available. The technique is reproducible, easily teachable and carries low morbidity and high patient satisfaction in carefully chosen patients.

The treatment of sulcus vocalis and vocal bowing has been commonly used Thyroplasty Type surgery or injection within vocal folds such as Teflon, silicone, collagen. However, and treatment has not been acquired satisfactory treatment effect. This study was conducted to demonstrate voice therapy effect using singer's vocal technique and respiratory training. 4 patients (1 male, 3 females) with sulcus vocalis or bowing, with or without scar were selected for this study and we compared with acoustic, aerodynamic measures and stroboscopy observation before and after voice therapy. The results showed that 1) case 1 (48yr, male) with sulcus vocalis decreased F0 (Fundamental Frequency), increase CQ(Close Quotient) and high degree of satisfaction but not improved voice quality after voice therapy. 2) case 2(19yrs, femal) with mild sulcus vocalis improved as normal voice quality after voice therapy. 3) case 3(38yrs, female) with functional bowing showed abnormalvocal contact before therapy whereas CQ was increased after voice therapy. 4) case 4(27yrs, female) with vocal atrophy and vocal bowing changed normal range of Fo and increased CQ after voice therapy. Even though contact area of both vocal folds was increased and lowered F0 after voice therapy, current outcomes revealed that normal voice quality was not regained. These results might signify that it was difficult that vocal folds couldn't be recovery of symmetry and viscoelastic property of mucosal wave through voice therapy. However, it was difficult for this study to maintain voice therapy so that evaluate effect of voice therapy for long-term. Further study will be needed to long-term follow-up for voice therapy with these patients.
