Chaotic signboards on the street make pedestrians unpleasant making light pollution by light reflection. Even though it is inevitable for stores to use lighting boards to compete each other where many stores are concentrated the government's management is necessary because the boards are exposed to the public. Today the percentage of illegal advertisement is over 50% and this is because institution related with advertisement has loopholes so we can't expect that lighting pollution will be lessened under the current regulation regime. By studying the current institution and regulations we conclude that we may minimize regulations and maximize characteristics and artistic values of signboards by regulating size and numbers of signboards by regions. In terms of lighting pollution excessive brightness of lighting signboards is closely related with brightness movement lighting color and ways of installment. Therefore it is clear that guidelines are necessary. However signboards are usually manufactured by petty and small producers so they can't follow the recommended brightness because tools for bright measurement are expensive and because there are variety of measuring methods. Hence it is pragmatic that institutional regulation should be carried out in licensing registering and managing in the process of signboards production. In other words,'integrated management system' with pre-registering regulation should be implemented which is based on the design process of signboards. This will secure the individual design of signboards and manage lighting pollution and detailed standards for the signboards production should be studied. 우리나라의 상업지역 내 옥외광고물 중 조명을 사용하는 간판들은 무질서한 난립으로 인해 보행자에게 불쾌감과 빛 반사로 인한 빛공해를 유발하고 있다. 이는 상가가 밀집하여 경쟁하는 구조에서 불가피한 일이라 할 수 있지만 공중에게 지속적으로 노출되어 있다는 점에서 관주도 하의 관리가 요구되어진다. 현재 우리나라의 간판현황에서 불법광고물의 비율은 50% 이상으로 이는 불법이 자행될 수밖에 없는 제도에 문제가 있다고 여겨지며 현 옥외광고물의 제도 하에서는 간판조명의 빛공해가 개선되지 않을 것으로 판단되어진다. 빛공해에 따른 발광광고물은 현행제도와 규제를 분석한 결과 간판의 개성과 예술성을 고려하고 규제를 최소화 할 수 있는 방법은 지역·권역별로 광고물의 수량 면적에 따른 크기 등을 제한할 수 있을 것으로 분석되었다. 빛공해에 있어 간판조명의 지나친 밝기는 휘도와 움직임 광색 설치방법과 밀접한 관련이 있다. 따라서 이에 따른 가이드라인의 기본 지침의 설정은 반드시 필요하다고 본다. 하지만 영세한 우리나라의 간판 제작실정에 비춰볼 때 휘도를 측정하는 기기의 비용문제와 다양한 측정방법으로 인해 권장 휘도를 따를 수 없다. 그러므로 실질적 적용을 위해서는 간판의 제작과정에서의 허가 및 신고 관리부분에서의 제도적 규제가 이루어져야 한다. 즉 간판을 제작하는 디자인 프로세스를 기반으로'사전신고제'를 통한'통합관리시스템'이 규제방안으로 제정되어야 한다고 결론지었다. 이는 간판의 개별디자인은 살리고 공중을 위한 관리의 규제는 이루어지는 방향으로 개선되어야 할 것으로 연구되었으며 향후 제도적 측면에서 규제할 수 있는 간판제작에 대한 구체적 기준마련이 요구되어진다.

본 연구는 간판조명을 LED조명으로 대체함으로써 얻어지는 에너지 절약과 그에 따른 CO2 배출 저감효과를 분석하여 에너지절약형 간판 보급 확대를 위한 개선방안을 모색하는 데 목적이 있다. 2009년 전수조사 현황에 따르면 총 광고물의 수량은 526만개로 2007년 대비 21%가 증가했으며 수도권 및 대도시의 광고물 수량이 높은 비율을 차지했다. 전기를 사용하는 간판은 총 간판 수량의 74%를 차지하고 표본조사 분석 결과 LED의 제작 비율이 점차 늘어나고 있음을 알 수 있다. 일반전기를 사용하는 간판 중 가로형 세로형 돌출형 간판이 전체 조명간판 중 93.2%를 차지하고 있어 이를 토대로 형광등과 LED의 단위면적당 소비전력량을 비교분석한 결과 1㎡당 소비전력량은 LED간판이 형광등 간판의 약 26%에 해당하며 연간소비전력량은 형광등 간판이 8,018GWh LED간판은 2,102GWh이다. 따라서 형광등간판을 LED간판으로 100% 교체 시 5,915GWh의 에너지 절감 효과를 볼 수 있고 이산화탄소는 약251만톤 전기요금은 약 4,135억원의 절감의 효과를 기대할 수 있다. 따라서 탄소 배출을 줄이고 에너지 절약을 할 수 있는 간판조명의 개선을 위한 정부의 적극적인 지원과 법체계의 명확화 민간주도 사업 방식으로 전환 인식의 제고 등의 개선 방안이 요구되어진다. This study aims to search for improving solution to expand distribution of energy saving signs by analyzing energy saving effect by replacing sign lighting with LED lighting and subsequent CO2 emission reducing effect. According to 2009 complete enumeration the total number of advertisement was 5.26mn 21% increased compared to 2007 substantial portion of which are located in metropolitan areas and big cities. In addition signs using electricity accounts for 74% of the entirety and ratio of LED manufacturing is gradually increasing according to sampling survey. Horizontal vertical and projected types comprise 93.2% of the entire signs operated by regular electricity. Upon the comparative analysis of energy consumption per 1㎡ of fluorescent and LED light LED sign is about 26% of fluorescent light sign and annual measurement of fluorescent light sign is 8,018GWh whilst LED sign is 2,102GWh. Therefore switching fluorescent light sign to LED sign completely can bring 5,915GWh of energy saving effect along with 2.51m tons of CO2 emission and 413.5bn KRW of electricity fee decrease. Given the fact government is required to support enthusiastically and to define the legal system for sign lighting improvement in order to curtail CO2 emission and save energy. Then it should be switched to private project led by civilians while enhancing their awareness.

Objectives To evaluate the feasibility of robot-assisted laparoscopic myomectomy in multiple myomas over 10. Methods A retrospective study was conducted for 662 patients who underwent robot-assisted laparoscopic myomectomy and open myomectomy by a single operator in a tertiary university hospital. Results A total of 30 women underwent removal of 10 or more uterine myomas by robotics and 13 patients were selected for this study. The average number of myomas removed was 13.7 (range 10-20). The maximum diameter of the myomas was 6.8 cm (range 5.0-10.0 cm). The sum of the diameters of each myoma was 34.7 cm (range 20.0-54.5 cm) and the mass of resected myomas for each case was 229.1 g (range 106.8-437.9 g). In no case was the robotic procedure converted into conventional laparoscopy or laparotomy, and all patients recovered without any major complications. In comparison with 13 cases of open myomectomy during the same period, robotic surgery took longer time than open surgery (360.5 vs. 183.8 minutes; P=0.001) but had shorter postoperative hospital days after surgery (mean 2.5 vs. 3.5 days; P=0.003). Conclusion Robot-assisted laparoscopic myomectomy could be an alternative to laparotomic myomectomy for numerous myomas over 10 in number.

Objective: Demonstrate a new instrument, technique or procedure Target: Adanced practicioners Methods: 35 year old married women came for heavy menstrual bleeding and subfertility; she failed IVF3 times before. In MRI, multiple myomas including Figo stage type 2 submucosal myoma were noted. For conserving fertility, we decided to robot assisted laparoscopic myomectomy. Real-time hystero-sonography was used to locate the embedded myoma and the exact incision site was determined. The serosa and myometrial layer was cut using the robotic monopolar scissors. To avoid thermal damage to uterus, vasopressin mixed fluid was used instead of coagulation. As the myoma is being removed, endometrial cavity can be visualize. At this point filling up the cavity with carmin fluid can help visualize endometrial cavity well. Furthermore, filling up the cavity with fluid can help detect any endometrial injury. And then, enucleation of myoma is possible. After the myoma is completely distracted, suturing is done with the PDS. Because we can locate the endometrial cavity, layer by layer suturing is possible. Results: Total 20 myomas were removed, and no endometrium injury was detected. Patient was recovered and discharged 2 days after operation. After 3 month, pelvic sonography was done, and distorsion of endometrial cavity was recovered and heavy menstrual bleeding disappeared. Conclusion: Myoma is one of the common gynecology disease. Although most myomas are benign, some kind of submucosal myomas can cause heavy menstrual bleeding and subfertility. In general, hysteroscopic resection is used for myomectomy but it may injure normal endometrium and cause adhesion. Robot asissted laparoscpic myomectomy can be a good option for submucosal myomectomy for the patient who want to conserve fertility.

We proposed modified laparoscopic sacrocolpopexy with peritoneal tunneling method to minimize complication and to shorten learning curve. These case series are to represent our experiences about modified laparoscopic sacrocolpopexy with peritoneal tunneling method. We retrospectively analyzed nine patients with symptomatic post-hysterectomy vaginal vault prolapse who were treated by modified laparoscopic sacrocolpopexy with peritoneal tunneling method at the St. Vincent’s Hospital and the Seoul St. Mary’s Hospital. We performed laparoscopic sacrocolpopexy without full dissection and repair of peritoneum. We could minimize complications and suturing time by making peritoneal tunnel in place of full dissection and repairing of the peritoneum over retroperitoneal mesh. We could find a restoration of pelvic floor anatomy after surgery. During follow-up period, there was no report of recurrence. We conclude that modified laparoscopic sacrocolpopexy with peritoneal tunneling method is one of the effective treatment option for vaginal vault prolapse patients by minimizing complications and shortening suturing time to repair the peritoneum over mesh during conventional laparoscopic sacrocolpopexy.
