Purpose: Deep inspiration breath hold (DIBH) is a well-established technique that enables efficient cardiac sparing in patients with left-sided breast cancer. The aim of the current study was to determine if DIBH is effective for reducing radiation exposure of of liver and other organs at risk in right breast radiotherapy (RT). Materials and Methods: Twenty patients with right-sided breast cancer were enrolled in this study. Three-dimensional conformal RT plans were generated for each patient, with two different computed tomography scans of free breathing (FB) and DIBH. Nodes were contoured according to the Radiation Therapy Oncology Group contouring guidelines. Dose-volume histograms for the target volume coverage and organs at risk were evaluated and analyzed. Results: DIBH plans showed significant reduction in mean liver dose (5.59 ± 2.07 Gy vs. 2.54 ± 1.40 Gy; p = 0.0003), V20Gy (148.38 ± 73.05 vs. 64.19 ± 51.07 mL; p = 0.0003) and V10Gy (195.34 ± 93.57 vs. 89.81 ± 57.28 mL; p = 0.0003) volumes compared with FB plans. Right lung doses were also significantly reduced in DIBH plans. Heart and left lung doses showed small but statistically significant improvement with application of the DIBH technique. Conclusion: We report that the use of DIBH for right-sided breast cancer significantly reduces the radiation doses to the liver, lungs, and heart.

Objectives: We used participatory mapping as a tool for empowerment training for promoting health and safety of farmers. We would like to introduce the application of participatory mapping method and report our experiences in a rural community in Korea. Methods: A one-day workshop was offered in six rural villages which were designated as 'safe farm zones'. Each workshop started with an orientation session, followed by a village rounding, presentations of best cases, a group exercise to draw and present a healthy village map. Participants were requested to express their ideas and experiences about healthy and safe residential and working environments on their map. Results: A total of 206 farmers(100 male, 106 female) participated in the workshops. In each workshop, an average of 34.3 farmers participated, and their mean age was 59 years. In the six workshops, the participants proposed a total of 137 action plans. The action plans included improvement of co-working condition, building facilities for recreation, improving traffic safety measures, and improving residential environment. Conclusions: Participatory mapping was successfully developed and applied as a tool for empowering Korean farmers. The participants were able to express their ideas and thoughts about healthy and safe village and action plans on the map. Moreover, some of the actions in the action plans were carried out immediately after workshop.

The purpose of this study is to suggest production planning model for women's apparel manufacturer, which are relevant to the situation of Korean clothing industry. The research was based on simulation method. The basic model for the simulation was developed based on the empirical data from six production fm. After verifying the basic model, low alternative production plans went through trial run. In order to suggest the application of these alternative production plans for various style numbers and lot sizes, the simulation results were compared in terms of product efficiency and product cost. The four alternative plans were as follows: 1. The first alternative was to spread out work loads among workers in order to resolve bottlenecks in work flow. So this was suited to manufacturers that had constant production without regard to changing seasons. 2. The second alternative was to merge the skirt and trouser production, which require less work load, in one line. In this line, a few machine was justified by production improvement. It was suited to cases which producted various style suits. The third and fourth alternative were using another subcontractor for assembling inner shell garments. These was compatible in manufacturers which had to product more styles and sizes of trousers and skirts than those of upper garments. 3. The third alternative was to reassign the same workers in production line. Thus, production was increased. 4. The fourth alternative was to except two worker in production line, so expenses of worker's wage was decreased. The four alternatives could be one of the cost effective manufacturing plans according to manufacturer situations.
As food waste problems become more severe, the need for reduction plans is increasing. Thus, this study aimed to discover the attitudes towards and the intentions to reduce restaurant food waste as well as the importance of and intentions to participate in reduction plans among adults customers A self-administrated questionnaire was given to 361 adults (216 men and 145 women) over 20 years old residing in Seoul and Gyeonggi province. According to the results, the respondents regarded restaurant food waste problems as serious (4.01). The biggest reason for leaving food was concern about hygiene (3.57), followed by tasting food (3.34) and portions that were too large (3.10). 57.6% responded that they try to reduce food waste when dining out. Women over 30 admitted to leaving food when dining out if the food did not taste as expected, if they had health concerns about additives such as condiments, and for body weight management. The overall average degree of awareness on the gravity of restaurant food waste problems was 4.06, indicating that respondents deeply empathized with the matter. Women showed higher alertness compared to men, and respondents in their 30s or over did more than those in their 20s. Also, respondents who try to reduce food waste when dining out had higher levels of concern than those who did not. According to the results from measuring the importance of and intention to participate in restaurant food waste reduction plans, taking away left-over food was the best option. In short, citizenship improvement campaigns should be designed for restaurants and related organizations in order to stimulate the need and effects of efforts to reduce dine-out food waste and induce aggressive participation by consumers. Diverse methods to increase actual consumer participation in food waste reduction plans that show high consumer participation intentions also needs to be developed.

To improve accuracy of dose calculation on kilovoltage cone beam computed tomography (kV CBCT) images, a custom-made phantom was fabricated to acquire an accurate CT number to electron density curve by full scatter of cone beam x-ray. To evaluate the dosimetric accuracy, 9 volumetric modulated arc therapy (VMAT) plans for head and neck (HN) cancer and 9 VMAT plans for lung cancer were generated with an anthropomorphic phantom. Both CT and CBCT images of the anthropomorphic phantom were acquired and dose-volumetric parameters on the CT images with CT density curve (CTCT), CBCT images with CT density curve ($CBCT_{CT}$) and CBCT images with CBCT density curve ($CBCT_{CBCT}$) were calculated for each VMAT plan. The differences between $CT_{CT}$ vs. $CBCT_{CT}$ were similar to those between $CT_{CT}$ vs. $CBCT_{CBCT}$ for HN VMAT plans. However, the differences between $CT_{CT}$ vs. $CBCT_{CT}$ were larger than those between $CT_{CT}$ vs. $CBCT_{CBCT}$ for lung VMAT plans. Especially, the differences in $D_{98%}$ and $D_{95%}$ of lung target volume were statistically significant (4.7% vs. 0.8% with p = 0.033 for $D_{98%}$ and 4.8% vs. 0.5% with p = 0.030 for $D_{95%}$). In order to calculate dose distributions accurately on the CBCT images, CBCT density curve generated with full scatter condition should be used especially for dose calculations in the region of large inhomogeneity.
The purpose of this study is to analyze the present condition of the landscape plans(LPs) established in the Rural Village Development Projects(RVDPs) and to propose the ways to improve the LP. Toward this end, the legal system related to rural landscape and the RVDP were examined. Also, the current condition of the LPs was diagnosed through making researches on the RVDP and LP of the 10 regions. The results of examining the legal system showed that the suitable types of the LPs is 'the Specific Landscape Plan' in Rural Area. Of the development projects that have been in operation, RVDP was found to have been equipped with the system. Because the LPs can be established and the contents of formation and readjustment of rural landscape elements were broadly dealt with in RVDP. And the RVDPs consisted mostly of scenery facilities, rural village sightseeing, and income-growth. The results of examining the plan establishment procedures showed that the LPs were set up as subordinate plans of the RVDP, so structural problems such as the positions of the plans, inadequacy in the procedures of approval and collecting opinions were identified. Such problems were pointed out as the cause of the LP to deal with the contents of the basic designs of the RVDP. The schemes to resolve the problems are to give equal positions to the LPs and to the basic plans of the RVDP. When the results of this study are reflected on the policies, the LP will effectively carry out the functions of formation and management of continued scenery preservation of rural villages.

This study is aimed at exploring the direction and characteristics of Japanese medical facility improvement in each area, a move to strengthen local medical services. Also, this study is intended to establish implications for Korea, which has similar social conditions as Japan's. Based on the findings, Japanese medical facility improvement has the following characteristics. First, as for medical service supply system, the linkage between facilities was being strengthened. The purpose is to share the functions and roles of limited medical facilities. It allows patients to receive complete medical services in one area. Second, local public health facilities were consolidated to boost their management efficiency and to improvement their original functions. Third, local medical facility roles were divided into different levels. The purpose is to treat patients more efficiently depending on their diseases. In other words, the cooperative medical system was strengthened by dividing the roles of medical facilities. It is aimed at treating each patient more systematically depending on their conditions in line with the treatment stage. The findings suggest the following for Korea. In order to supply and maintain stable medical services regionally in line with social changes, functional issues of medical facilities should be tackled consistently and systematically.

Recently, the National Research Foundation of Korea (NRF) announced new plan to reflect the KCI citation measures in journal evaluation. In principle, Journal evaluation should reflect each journals situation and characteristics through various indicators. In this study, three improvement plans were proposed by reviewing the announced journal evaluation plan of NRF. The first improvement is to consider the five-year IF as an additional citation measure; the second improvement is to allow flexible selection of the category level on which to rank journals; and the last improvement is to combine the previous two methods and apply them together. The improvement methods proposed in this study are expected to contribute to minimizing side effects of KCI journal evaluation.
This study initially analyzes the meaning of Community-Based Residential Environment Improvement. A residential environment improvement factor was determined through an analysis of the function, components, Planning techniques of the community, the evaluation criteria of the residential environment, and through relative literature documenting plans for the adjustment of urban and housing environments. In terms of the methodological approach, decisions were made based on the results of an expert focus-group-interview, a goodness-of-fit test, and by using the analytic network decision-making method from which the correlation among items can be considered. Results of this analysis show that the, order of importance of factors for a community-based residential environment is as follows: interactional character, cognitive character, and locational character. Furthermore, the most important aspect for each of these factors are the neighbor-hood relationship in terms of the interactional character, common consciousness for the cognitive character and place for locational character. The results of this study can be used by linking them with questionnaire items for basic resident research when a residential environment improvement project or a plan for the adjustment of urban and housing environments is planned.
