Purpose: To quantify the cardiac dose reduction during breathing adapted radiotherapy using Real-time Position Management (RPM) system in the treatment of left-sided breast cancer. Materials and Methods: Twenty-two patients with left-sided breast cancer underwent CT scans during breathing maneuvers including free breathing (FB), deep inspiration breath-hold (DIBH), and end inspiration breath-hold (EIBH). The RPM system was used to monitor respiratory motion, and the in-house self respiration monitoring (SRM) system was used for visual feedback. For each scan, treatment plans were generated and dosimetric parameters from DIBH and EIBH plans were compared to those of FB plans. Results: All patients completed CT scans with different breathing maneuvers. When compared with FB plans, DIBH plans demonstrated significant reductions in irradiated heart volume and the heart $V_{25}$, with the relative reduction of 71% and 70%, respectively (p < 0.001). EIBH plans also resulted in significantly smaller irradiated heart volume and lower heart $V_{25}$ than FB plans, with the relative reduction of 39% and 37%, respectively (p = 0.002). Despite of significant expansion of lung volume using inspiration breath-hold, there were no significant differences in left lung $V_{25}$ among the three plans. Conclusion: In comparison with FB, both DIBH and EIBH plans demonstrated a significant reduction of radiation dose to the heart. In the training course, SRM system was useful and effective in terms of positional reproducibility and patient compliance.

The purpose of this study is to investigate how the 6 entry plans of Seoul Park in Paris were representing the tradition by comparing and reviewing them. Entry plans proposed for Seoul Park revealed different approaches of representing traditional gardens. Through scrutinizing these plans, some similar and different aspects among them could be found out. In order to find out those aspects, the entry plans were analysed and compared into several categories such as design concepts, programs and spatial components. The main concern for analysing the entry plans focused on the issue of are presentation. Representing a Korean garden into Seoul Park depends on the manner of a representation, their objets and media. Objects are related to the contents. The contents can have various themes, events, places beyond the garedn. Meids is related to represent Korean tradition with what implement. The manner of a representation can be divided into three types; a direct representation, an abstract(metaphoric) representation and a destructive representation. We found the characteristics through analysing the entry plans that 1) Korean terrain, Korean thoughts, narrative promenade, past/present/Korea/Seoul, story telling through the Korea traditional fence were used as design concepts. 2) Traditional elements such as a traditional pavilion, fence, madang, hwagye, gate were generally chosen as essential elements for representing the Korean tradition. 3) Direct representations were ore broadly used than abstract and destructive representation as the manner of a representation. and 4) The entry plans show us a variety of possibilities of representing traditional gardens. Abstract and destructive representations of tradition can be found out in th several plans compared with other existing ocean gardens made in foreign countries. In establishing urban parks and ordinary landscapes, those strategies can be alternatives to represent the identity of Korea by reconciling tradition with invention.

The purpose of this paper is to propose directions for urban greening and nature conservation in small-to-medium-sized cities in Korea for implementation of the Local Agenda 21 (LA 21 hereafter). In this paper, the status of implementation of the LA 21 in both Korea and Japan have been examined. In addition, the green-related plans of both countries have been compared. The cities of Jeonju and Sagamihara were chosen as examples to compare. The result of the research is as follows: 1)With regard to the responsible bodies, in Korea, the implementing plans were initiated by the environment-related authorities of local governments while, in Japan, the plans of action were initiated through consultative committees reflecting opinions from citizens and business entities. 2)Concerning the status of implementation of LA 21, the city of Jeonju has adopted a plan of action and then implemented the plan through a consultative body without adequate legal ground. On the other hand, the city of Sagamihara has enacted a local ordinance to implement the LA 21 It was learned that the newly enacted ordinance has positively been interrelated to existing environmental plans. 3)Regarding urban greening and nature conservation plans, the city of Jeonju has focused on comprehensive measures to preserve and restore ecology while the city of Sagamihara has clearly suggested educational purposes in its plans in addition to preserving and restoring ecology. 4)In terms of support by law or legal system concerned, it has been teamed that, compared with Japan, Korean plans have not been properly supported by law or the legal system to urban greening and nature conservation plans. The same was shown in the city of Jeonju as compared with the city of Sagamihara. As for future directions, the follow are proposed: 1) establishment of a local Committee on Sustainable Development, 2) enactment of relevant and regulations such as the Master Plan of Parks and Green Open paces, 3) establishment of ecological greening plans.

Even though there have been greate changes in the types and contents of the housing plan in Korea since the Modem age, it seems that the identity of traditional dwelling culture is still remains within it. The purpose of this study is to examine the characteristics and features in the development of the 'Public Standard' Housing Unit Plan by comparing the differences and similarities in unit plans in housings built on Japanese occupation period and those built after the period. From the study, we can conclude as follows: 1. The public standard housing unit plans on both periods have shown the common features in the composition of their physical forms in the way that the front-row area still remains the traditional housing culture and the rear-row area reflects the desires of the modem lives. The structure of the dual-row unit plan appeared in the public standard housing plan was caused by the cultural acculturation in Japanese occupation period. 2. The public standard housing unit plans, however, show the differences in the contents and meaning in units plans with the them of the Japanese housing because of the cultural differences. These differences took placed autonomously through the change of housing plans in the modern time, and have the common features such that 1) the changes in the Maru-centered plan type differ in composition from the inner-corridor plan type used Japanese housing, and 2) the composition of the open-inner spaces in the double-row housing plan reflects the single-row outer open space In the traditional housing. All of these cultural progresses in the public standard housing unit plans was took place as the result of the inner-oriented and notional circulations derived from the modernity. However, the transformed unit plans still contains the identity derived from the variation of the traditional Korean building elements such as Maru and Ondol. In other words, those are the Maru-centered and composed housing plans with juxtaposition of the inner block and the outer block. As the conclusion, though the public standard dwelling unit plan has the similarity in the physical form, it is different in the cultural Identity and meaning from the public standard plans before the independence from the Japan occupation.

Apartment buildings represent the most typical patterns of housing in Korea. The present plans are very different from the previous ones when they appeared for the first time. Although apartment unit plans has changed drastically, they can be classified into several categories. Apartment unit plans reflects the demands of living activities and space dimensions of unit plans have the characteristics of diachronic continuity and carry the values of living culture. Thus this study aims to provide the statistical dimensional data of each room that can be actually used for the design of unit plans by sub-grouping typical unit plans. The statistical data of this study showed that apartment unit plans are shifting from 2bay/3room type to 3bay/3room type in 1990s. It is very peculiar that the typical unit plan of $60\;m^2$ area becomes to resemble that of $85\;m^2$ area. The space arrangement of typical unit plans of both $60\;m^2$ and $85\;m^2$ area is almost identical while only their space dimensions differ slightly. As the mean/mode/median values of space dimensions in a typical unit plan are converging into a range of narrow margin, space dimensions of typical unit plan are contended to be strictly regular. The statistical numeric data of various space dimensions provided in this paper can be applied practically to the design of apartment unit plans for low income class people who are disprivileged in the society.

Purpose: To evaluate the effect of common three photon energies (6-MV, 10-MV, and 15-MV) on intensity-modulated radiation therapy (IMRT) plans to treat prostate cancer patients. Materials and Methods: Twenty patients with prostate cancer treated locally to 81.0 Gy were retrospectively studied. 6-MV, 10-MV, and 15-MV IMRT plans for each patient were generated using suitable planning objectives, dose constraints, and 8-field setting. The plans were analyzed in terms of dose-volume histogram for the target coverage, dose conformity, organs at risk (OAR) sparing, and normal tissue integral dose. Results: Regardless of the energies chosen at the plans, the target coverage, conformity, and homogeneity of the plans were similar. However, there was a significant dose increase in rectal wall and femoral heads for 6-MV compared to those for 10-MV and 15-MV. The $V_{20Gy}$ of rectal wall with 6-MV, 10-MV, and 15-MV were 95.6%, 88.4%, and 89.4% while the mean dose to femoral heads were 31.7, 25.9, and 26.3 Gy, respectively. Integral doses to the normal tissues in higher energy (10-MV and 15-MV) plans were reduced by about 7%. Overall, integral doses in mid and low dose regions in 6-MV plans were increased by up to 13%. Conclusion: In this study, 10-MV prostate IMRT plans showed better OAR sparing and less integral doses than the 6-MV. The biological and clinical significance of this finding remains to be determined afterward, considering neutron dose contribution.

The purpose of this study is to give some suggestions for the legal supplement of the regulation on the balcony expansion for the optimal use of apartment balcony. For the purpose, this study focused on the characteristics of spaces expanded to the balcony, in the plans supplied after the legalization of balcony expansion, comparing them by their location; the metropolitan area of Seoul Gyeonggi and the districts of the other areas. The 168 plans of apartments in the supplied by top 10 constructors in the metropolitan areas of Seoul and Gyeonggi, together with the 92 plans in the other smaller districts in 2006 to 2007 were analyzed with the tools of frequency and chi-square analysis. The result is as follows. (1) The region showed no difference in the plans of balcony; whereas the size, the position and access of the shelter explained some differences of balcony plan. (2) In wider plans, balconies were placed in all sides of plan-front, rear and side, and were remodeled to expand facing rooms. (3) The balcony expansion tended to increase the number of bays. (4) In almost cases, the living rooms were expanded to balcony. In smaller plans, the balconies were remodeled to supply supplementary kitchen space, splitting it from laundry. (5) The shelters were placed at the rear or side of plans, but the shelter facing room could be dangerous in case of fire. The balcony expansion, despite of legalization spirit to adopt diverse use of additional spaces for residents' needs, was only a tool for the space expansion. The amendment of the regulation is needed to accommodate these findings that the balconies should be identified by their function, that the front corridor-type balcony should be limited in length and magnitude, and that the shelter should be positioned with easy access.
