Background: The epidemiological patterns of cancer incidence have been investigated widely in western countries. Nevertheless, information is quite limited in Jiangxi province, southern China. Materials and Methods: All data were reported by 6 population-based cancer registries in Jiangxi Province. The results were presented as incidence rates of cases by site (ICD-10), sex, crude rate (CR), age-standardized rates (ASRs) and truncated incidence rate (TR) per 100,000 person-years, using the direct method of standardization to the world population. Results: 8,765 new cancer cases were registered in our study during the period 2009-2011. Diagnosis of cancer was based on histopathology in 61.0%, clinical or radiology findings in 4.87% and death certificate only (DCO) in 3.0% of the cases. The median age at diagnosis was 62.0 years (mean, 61; standard deviation, 15). The ASRs were 170.8 per 100,000 for men and 111.2 for women. The ASRs for all invasive cancers from the urban areas (145.7 per 100,000) was higher than that of rural areas (137.1). Incidence rates for lung cancer were higher in rural (35.8) than in urban areas (27.0). Similarly, relatively high rates were observed for stomach cancer in rural (20.1) relative to urban areas (15.5). Conclusions: Our results reveal that the most common cancers were breast and lung in women and lung and liver in men. Interestingly, this study suggested a higher incidence rates for lung and stomach cancer in rural males than in urban population, which may suggest other potential causes, such as over-consumption of smoked meats and high prevalence of Helicobacter pylori infection, respectively. Public education and the promotion of healthy lifestyles should be actively carried out.

We carried out this study to reduce the gaps between medical institutes and between medical personnels and help to improve medical service quality, by classifying diagnoses and related intervention through the development of standard nursing intervention and by computerizing protocols. We considered two processes: one is the development process of home nursing standard intervention, and the other is the process of computerizing its related protocols. For the former, research covered analysis of home health care practices, development of client assessment protocol, of patients diagnosis protocols, and of patients intervention protocol. For the latter, strategies for home health care information systems should be set up and it constituted four research contents of analysis, design, management and evaluation of the systems. We also trained and educated home nurses who work at home health service center, by making them use the manual of home health care information systems at a certain city of P. In this study, therefore, we developed elements of standard home health care mediation so that they could be included in the forms of home health information note, home health progress note, and home health progress summary, home health discharge summary. Because standard home health care intervention has been developed, it became easier to exchange information between different home heath service center offices, can prevent from missing or redundant information, and contribute to standardization of hospital terminologies when EMR and HMR are developed.

The purpose of this survey was to investigate the operation and the environment of foodservice in elementary schools nationwide. A questionnaire about foodservice management to practice and foodservice operation was mailed to dietitians of each school . Of the 1, 416 schools that participated in this survey, 388 schools were selected for analysis. The main results of this study are as follows. More schools in small cities . Education levels of dietitians were significantly different from area to area. Mean total length of employment for dietitians at school foodservice was 4.7 years and varied significantly by area and the type of foodservice system. Foodservice has been operated for 2-5 years in most of schools. Schools in large cities served more people than those in small cities and rural areas. Also , schools adapting conventional foodservice system served more people than those adapting commissary or joint management system. Foodservice expense also veried significantly by area and foodservice systems. Mean foodservice expense per meal were significantly higher in schools adapting commissary system than those adapting other systems. Most schools employed dietitians, cooks, and assistant cooks, but not engineers not drivers. Mothers of students were working voluntarily. The degree of participation by mothers in cooking , serving , and cleaning was higher in schools of small cities and rural areas than those in large cities, in schools adapting commissary or joint management system than those adapting conventional system. Education and training ranked as personnel management had one of the hardest tasks. Education and training of employees were also difficult for dietitians, especially in commissary or joint management systems. Percentage of schools having separate lunchroom was higher in small cities rural areas than in large cities, in joint management or commissary system than conventional system. Most difficult matters in serving was the portion control. Over 40% of schools did not use standard recipes. Menu cycles were shorter in schools in small cities and rural areas which adapted the joint management system than area other schools. Except refrigerators, thermos , display racks, sterilizers, sinks, worktables, and table, all other equipment were insufficient in most of schools. More than half of the schools didn't have rice cookers, flatware racks, and distributing carts which are stated plainly in detailed enforcement regulations for school foodservice. Cooking equipments were described as the most needed by dietians. According to the results of this survey, many and urgent problems need to be addressed improve the quality of school foodservice . Lunchroom setups, effective personnel management and expenses, recipes standardization, serving size control and regular checking and repairing of equipments are all problems to be addressed.

Many problems which today's research libraries are confronted with should be taken the measures to find some solutions in any ways. The purpose of this study is to identify the main stream of chaining of research libraries as an existing collector and distributor of scholarly information into a communication system adopting the concept of resource sharing and on-line bibliographic search as some possible ways for solutions. The conclusions of this study can be summarized as follows: 1) The research libraries will be imposed on more and more responsibilities to be a reservoir of the intellectual heritage of an individual, a nation and mankind. 2) The research libraries in the near future will have to develop their collections in the new environment of austerity with the limited budget. 3) It is more desirable for the future research libraries to have the attitude that they are in the business of information and communication rather than being an entity as "a library". 4) The resource sharing developed to solve the severe problems confrontal by research libraries will improve the organizational and technical mechanism for the access to the scholarly information. 5) The research libraries will produce more and more bibliographic database to expand the library materials which can be available and shared. 6) Though on-line search service will be sure to provide a considerable profit to the scholarly information users, it will take a long time for this service to be popularize because of the high ratio of service fee. 7) Two problems should be solved for the efficient service by on-line search. One is the continuous, updating training for the professional librarians. The other is that the common efforts for the quality control and standardization of data base by the data base producers should be made. 8) Taking all the items of the conclusions derived from the study of research libraries mainly in the United States into a consideration, the followings should be paid an attention. - The status-quo of the research libraries in Korea should be analyzed in very detailed and accurate way. - The problems of research libraries in Korea as the major scholarly communication system should be clarified based on the analysis. - The measures for the problems should be taken in the light of the unique characteristics of korean environment. - For the developing the most efficient measures, the formal organize action to lead and govern the long-aimed study on the problems of research libraries should be established and the government-level su n.0, pport for the legislation and finance should be provided for the realization of the result of the study.

Military Barracks and Bachelor Officer's Quarters are public buildings representing architectural characteristics with repeating the same room modules. These buildings require easy dismantling and reusing for the next generation' military re-organization. For these reasons, since 2005, the modular construction has been applied to military buildings. The most important factors required for modular military buildings are standardization, lowcost construction and reusable construction method. However, conventional modular building system have not been matched with these requirements. This study suggests a new modular system for Bachelor Officer's Quarters using Six-sigma design tool. To reflect the voices of customers, market study and surveys were carried out. Through the QFD, the voices of customers were converted into quality characteristics of building system for BOQ. The various design concepts meeting customer's requirement were derived by the QFD and Pugh matrix methodology. The proposed modular building system shows 80% increased factory production rate and 62% decreased weight of steel frame as compared with the conventional modular building system.

This study was performed to induce a quality improvement and standardization of materials used for greenhouse. For this purpose, physical and mechanical properties of agricultural films for greenhouse were measured by kinds and thickness of the films. The properties are composed of impact, tensile, tear propagation strength and light transmittance. The results were summarized as follows. 1. At the impact test result of the falling dart, the thicker the film, the greater the impact strength of soft film. The impact weight at 50 percents is from 158g to 213g and the strength of low density polyethylene(LDPE) film is higher than the rest of any other films. 2. Seeing the leveling of the impact rupture, maximum impact weight which was ruptured very little ranges from 62g to 192g. The impact strength of 0.1mm films was higher than that of 0.05mm as from 1.8 to 3.2 times. 3. Tensile weight covers from 0.95kg to 2.22kg in the test materials, and the weight of lengthwise film is larger than that of width. LDPE film has high value of tensile weight. Elongation range is from 345 to 102 percent and lengthwise elongation is greater than width as much as from 1.4 to 2.7 times. 4. Tea. propagation strength ranges from 80.5kg/cm to 121.7kg/cm, and unlike which of LDPE film has high value, EVA film has low value in the films tested. The width strength is higher than the lengthwise. 5. The light transmittance of the soft film is about 78-92 percent in the range of ultraviolet ray, but has high value in the visible ray range.

Purpose : Recently, cancer has become a chronic disease that requires supervision because of early diagnosis and the development of therapeutic technology. As a result, cancer patients are interested in improving the quality of their lives besides the treatment of cancer itself. Therefore, it is necessary to conduct a qualitative research to understand the vivid experiences of cancer patients and structure their treatment experience. Among qualitative researches, grounded theory is developed based on the data collected in the field. The grounded theory research method is easy to analyze for the process and structure of the treatment experience. Therefore, the purpose of this study is to provide basic data on the integrated medical experience of cancer patients Methods : Participants were conveniently selected, and the criteria for selection were for those who had more than 1 month of hospitalization so that they could dictate their situation and experience in a meaningful manner. Data was collected through in-depth interviews and continued until the data were saturated through theoretical sensitivity and continuous comparison methods. The collected data were analyzed through the process of open-coding, axial coding, and selection coding, which are the research methods of grounded theory. Results : Cancer patients differ in their path, purpose, and attitudes depending on their respective situations and the internal and external resources of individuals. There is also a difference in the perception of their situation among the cancer patients and their families. Cancer patients were shown to recognize and cope with problems in the integrated medical treatment process, and have been classified into 6 different types after the results. Cancer patients showed positive changes in terms of physical, emotional, and lifestyle after their integrated medical treatment. Cancer patients perceived the integrated medical treatment process as a horizontal relationship structure and with diversity. Conclusions : The experience of integrated medical treatment of cancer patients is a process of rehabilitation that heals the body and restores life within the interaction of support system, contextual situation, and internal resources of the individual. Despite this, there is a need not only for the efforts of integrated medical service providers but also institutional support in the future with regards to the current weaknesses and points for improvement. In addition, there is a need for an objective criterion to measure the outcome of integrated medicine for the standardization of integrated medical services.

The added levels of dongdong-ju, soy bean and fermentation time were selected as factors affecting the quality of Jeung-pyun (Korean fermented steamed rice cake) through pretest. The standing height ratio was significantly raised after the 1st and 2nd fermentation by the soy bean treatment. As the amount of dongdong-ju and soy bean were increased, the values of specific volume and expansion ratio for Jeung-pyun were increased. The effects of fermentation time did not show any significant differences. The pH of Jeung-pyun dough was significantly higher when the amount of dongdong-ju decreased and the amount of soy bean increased. Reducing sugar content of Jeung-pyun significantly augmented with raised amount of soy bean. As the amount of soy bean was increased, the hardness, springiness and cohesiveness of Jeung-pyun measured by rheometer significantly decreased. The optimum conditions for Jeung-pyun preparation were found to be 30g dongdong-ju, 2g soy bean solid and 180 minutes of fermentation time per 100g rice flour basis. Soy bean treatment had primary influence on Jeung-pyun preparation.
