The target must be located within the main-lobe of the antenna in order to measure the direction of the target by using sum-delta monopulse technique. The most common way if the target is located within the main-lobe is to compare the amplitude of the sum channel received signal with the delta channel received signal. However, in the case of the single-ring circular array antenna, it is difficult to apply the conventional method due to its structural limitation where antenna elements do not exist in the center of the array. In this paper, we proposed a novel method to identify whether a target is located within the main-lobe by appropriately adjusting the feeding amplitude of each element constituting the single-ring circular array antenna through the particle swarm optimization method. Simulation results showed that the proposed method can determine whether the target is located within the main-lobe of the single-ring circular array antenna.

This paper researches the features of blood stasis theory of Wangqingren, who wrote 『Yilingaicuo』 that greatly contributed in the development of blood stasis theory at Qing dynasty period. And the disease cause, disease mechanism of blood stasis and scope of modern diseases related with blood stasis are studied by research on clinical papers which used 33 prescriptions in 『Yilingaicuo』 in modern times. Research on the features of blood stasis theory of Wangqingren is proceeded by referring to the annotations of 『Yilingaicuopingyi』 and the papers which related with blood stasis from Korea and China. And clinical papers are searched in China Academic Journals(CAJ) of China National Knowledge Infrastructure(CNKI) to analyse the scope of modern diseases related with blood stasis. The features of blood stasis theory in 『Yilingaicuo』 expanded the range of existing theory. Wangqingren thought that chronic disease, weird disease, the disease of no effect from normal treatments were related with blood stasis. And he attached great importance to qi and blood and thought that the main pathogenesis of blood stasis was qi deficiency. And a lot of Astragalus membranaceus Bunge were combined in many prescriptions to reinforce qi. He also used different herbs according to the location of the disease. Musk and Allium fistulosum were used for the disease located at head or upper part of the patient's trunk. Bupleurum falcatum L., Aurantii Fructus Pericarpium and Platycodon grandiflorum A. De Candolle were used for the disease located at thorax. Cyperus rotundus L., Linderae Radix and Aurantii Fructus Pericarpium were used for the disease located at the stomach or below the costal angle. Foeniculi Fructus and Corydalis remota were used for the disease located at belly or lower part of the patient's trunk. Trogopterorum Faeces, myrrha, Cyperus rotundus L. and Cnidium officinale were used for the disease located at extremity or joint.

This study aims to interpret the location of 4 traditional settlements in the Youngnam district of Korea in view of geomorphology. For this study, GIS techniques were used to analyse quantitatively the degree of slope, slope aspect and the relation with river/stream of these regions. Yugok is located on pediment in the valley basin. Cheonjeon is located in the end part of the hill. Hahoe is located on the convex natural levee of the flood plain. Yangdong is located on a hillside. Houses are mostly distributed with south, southeast, and southwest aspect, but in Hahoe face all sides. Also, the settlements are located on average $10{\sim}20m$ above river bed. This indicates a safe height above river bed for avoiding an flood damage. These results imply that the location of the traditional settlement is based on a scientific logic and rationale. It is thus argued that the settlements satisfy exellent geomorphic conditions from the perspective of modern theories of residential location.

The purpose of this study is to analyze the approach characteristics, relation to other facilities, and current status focusing on 28 total of exhibition-culture facilities in Gangneung. The results are following as. First, 19 facilities are located in urban area and nine are located in country side. With locational characteristics of Gangneung which is mountains in west and sea to east, three are located in high hill side and four are in sea shore among nine facilities. Facilities in urban area converge to Gungpodae and Ojukhuk which are symbol space in Gangneung. Those facilities started to have been increased from 1990s and rapidly increased from 2000s. The reason is that people have been interested in culture and art in society in general. In building structure, buildings related with traditional contents were constructed with wooden structure while buildings have been mainly constructed with modern ways such as steel and reinforced concrete structure. Second, the 28 facilities are classified into three types by function of other space or facilities within same a site or a building. The three types are themselves usage only, multi-function, and park type. The multi-function type is re-classified into two; public type and commercial type. Those functions have changed according to changes of society and times. Finally, for approaching to the exhibition-culture facilities with general transportation, the mean distance from the closest bus stop to those facilities each is 280m and 27 facilities are located within 670m from the closest bus stop. For approaching way using by car creates movement along road-building site-parking space-main entrance of building. When based on main entrance by the movement, parking space located in front side of main entrance is the largest, next is in the side, and the least is in back side. Various factors such as approaching form from road to parking space and space size between main entrance and parking space influence to approaching ways of exhibition-culture facilities in Gangneung.

This paper presents the numerical calculation for input impedance of a conductor located in the loss media by using the program with MATLAB. The input impedances of the conductor were numerically calculated with the moment of method. To increase an accuracy of results, the Galerkin's method which both the basic function and the weight function are the triangle function was applied. And by applying the modified image method, image sources of the conductor located in air were considered. According to the comparison between the current distributions at the conductor which were calculated with the MATLAB program and the NEC program, the reliability of the self-made program with MATLAB was obtained. In case of the conductor located in soil, which length are 1 m and 2 m, the input impedance were simulated as a function of both a conductivity and a frequency. Finally, input impedances and phases of the conductor located in soil were measured, and those results were compared with simulated results which calculated under the same conditions.

Background Breast-conserving surgery is widely accepted as an appropriate method in breast cancer, and the lateral thoracodorsal flap provides a simple, reliable technique, especially when a mass is located in the lateral breast. This study describes the usefulness of a lateral thoracodorsal flap after breast conserving surgery in laterally located breast cancer. Methods From September 2008 to February 2013, a lateral thoracodorsal flap was used in 20 patients with laterally located breast cancer treated at our institution. The technique involves a local medially based, wedge shaped, fasciocutaneous transposition flap from the lateral region of the thoracic area. Overall satisfaction and aesthetic satisfaction surveys were conducted with the patients during a 6-month postoperative follow-up period. Aesthetic results in terms of breast shape and symmetry were evaluated by plastic surgeons. Results The average specimen weight was 76.8 g. The locations of the masses were the upper lateral quadrant (n=15), the lower lateral quadrant (n=2), and the central lateral area (n=3). Complications developed in four of the cases, partial flap necrosis in one, wound dehiscence in one, and fat necrosis in two. The majority of the patients were satisfied with their cosmetic outcomes. Conclusions Partial breast reconstruction using a lateral thoracodorsal flap is well matched with breast color and texture, and the surgery is less aggressive than other techniques with few complications. Therefore, the lateral thoracodorsal flap can be a useful, reliable technique in correcting breast deformity after breast conserving surgery, especially in laterally located breast cancer.

Background As the breast cancer incidence has increased, breast-conserving surgery has replaced total mastectomy as the predominant procedure. However, centrally located breast cancers pose significant challenges to successful breast-conserving surgeries. Therefore, we performed partial mastectomy and oncoplastic procedures on centrally located breast cancer as a means of partial breast reconstruction. The authors examined and evaluated the functional and aesthetic usefulness of this reconstruction method. Methods From January 2007 to June 2011, 35 patients with centrally located breast cancers who underwent various oncoplastic procedures based on the breast size and resection volume. The oncoplastic procedures performed included volume displacement surgical techniques such as purse-string suture, linear suture, and reduction mammaplasty. Other oncoplastic procedures included volume replacement procedures with an adipofascial, thoracoepigastric, intercostal artery perforator, thoracodorsal artery perforator, or latissimus dorsi flap. Results Mean patient age was 49 years, and mean follow-up period was 11 months. In cases of small to moderate-sized breasts and resection volumes <50 g, volume displacement procedures were performed. In cases of resection volumes >50 g, volume replacement procedures were performed. In cases of larger breasts and smaller resection volumes, glandular reshaping was performed. Finally, in cases of larger breasts and larger resection volumes, reduction mammaplasty was performed. This reconstruction method also elicits a high patient satisfaction rate with no significant complications. Conclusions In centrally located breast cancer, oncoplastic surgery considering breast size and resection volume is safe and provides appropriate aesthetic outcomes. Therefore, our method is advisable for breast cancer patients who elect to conserve their breasts and retain a natural breast shape.

The purpose of this study are to analyze the realities and characteristics of the inflow manufacturing factories located in non-urbanized area in the Capital region, and to extract the problems from locational point of view during the last 10 years. Using the raw data of factory registration statistics from 2006 to 2015, this study has intended to show the distributional characteristics of the independently-located manufacturing factories by various mapping methods. As a result, about 90% of the factories are heavily concentrated into 10 adjacent regions to Seoul and large cities. This study carried out questionaire surveys and in-depth interview to the leaders of Janganmyeon, Hwaseong-shi which have experienced the rapid increase of manufacturing factories. The independently-located factories have caused environmental pollution, destroyed rural village landscape, and affected the negative impact of the neighborhood community. The results of this study provide some implications to establish a desirable industrial location policy of non-urban areas in Capital region.
