This study has been performed to measure the prevalence and microbial flora on chicken slaughtering as well as the processing process from the months of October to November. Whole-chicken rinsing technique was used in order to analyze the incidence of microorganisms on chicken carcass at the stage before chilling (after evisceration), after chilling and after cutting. The swab technique was used on processing the processed samples, such as working plates and cutting knives. Brine and cooling water from four cooling tubs were taken from each processing processes and were used as samples. Furthermore, the matrix-assisted laser desorption/ionization mass spectrometry (MALDI MS) for whole cell fingerprinting in combination with a dedicated bioinformatic software tool was used to identify the isolated microorganisms. Of the tested samples and processes, brine ($4.50{\pm}0.64$ Log CFU/mL) and chicken carcass before chilling ($4.15{\pm}0.46$ Log CFU/mL) showed the highest population of microorganisms; the predominant microbial flora of them were Moellerella wisconsensis (54.84%), a member of the Enterobacteriaceae family, and Escherichia coli (60.36%), respectively. However, the predominant microbial flora of cut carcass was changed to Staphylococcus aureus (27.32%), which is a kind of pathogenic microorganism that can cause a food-borne illness. Therefore, the slaughtering and processing procedure of chicken are needed to be controlled more hygienically.

Life quality in farming areas is declining these days on account of decrease in population with the outflow of young generations, advent of aging society, and also lack of social and physical infrastructure. To reverse this, the central and local governments have been devising policies in many ways; however, the vulnerable class in farming area suffering from financial difficulty is not supported with that properly. The results of applying insulation materials applicable to rural houses, EPS, e-board, and glass wool, actually to rural houses are summed as follows. EPS is the most inexpensive among the three installations in terms of material cost and expenses. The indoor and outdoor temperature difference increased from $0.9^{\circ}C$ to $2.5^{\circ}C$, and the temperature change reduced as $0.04^{\circ}C$. With e-board, the indoor and outdoor temperature difference increased from $3.3^{\circ}C$ to $7.5^{\circ}C$; however, the temperature change increased as $0.09^{\circ}C$. Unlike the other two methods, glass wool requires the additional installation of wooden frames. The material cost is highest, and the indoor and outdoor temperature difference increased from $1.1^{\circ}C$ to $8.0^{\circ}C$, and the temperature change reduced as $0.01^{\circ}C$. According to the results of measuring temperature, glass wool's temperature difference is measured to be the highest, but temperature change is found to be the most effective in EPS. Among the three insulation methods, EPS is the most economically advantageous as the material supply is easy and the cost is low. The material is easily processible, so ordinary town residents can install it easily, and it is effective at improving insulation performance, too. But this method cannot be applied when the house has walls that are not even. Also, as the insulator is thick, after the installation, the living space may be narrower as a result.

The Korean rural landscape has changed significantly due to nationwide modernization and industrialization in recent years. Moreover, as urbanization progresses due to population and economic growth, rural areas surrounding the suburbs of cities are feeling the pressure of encroaching urban sprawl. Use of land for human-made structures such as road and housing development is also increasing, resulting in the destruction of nature in rural areas. Adopting a concept of conserving rural landscape in future development projects is therefore highly desirable.The main focus of this study is to look into the traditional concept of the village and to classify some elements of the traditional rural landscape. Daegu Metropolitan City, the third metropolitan city in Korea, is chosen as the subject of the study. The existing 227 villages have been studied on the basis of their principles and types of village locations in relation to the traditional concepts of 'Feng-shui' and 'Tackriji'. The characteristics of the village location are divided into two aspects: the natural landscape, such as topography, hydrosphere, and azimuth, and the historical and cultural landscape, such as customs(Only the natural landscape aspect is included in this study). The natural landscape, a condition of the village location, is divided into three areas: topography, hydrosphere, and azimuth. There are two types of topography: flatland type and mountain type. There are two sub-types in the mountain type: ridge and valley, which depend on the village location in relation to the shapes of the mountains. There are four types of hydrosphere which include waterways and three directions of mountain depending on the shape: front, behind and side. The direction of the village is analyzed from the direction which the houses in the village face. Therefore, the natural landscape element as a condition of the village location is closely related to the traditional concepts of the village.

This study has analyzed overseas projects of building rural communities using vacant houses. It is aimed at identifying the roles of NPO in the community-building projects and providing implications applicable to Korea. In recent years, there has been a spike in the number of vacant houses in rural areas. It is due to rapid urbanization and uneven distribution of the population across the country. Those are the reasons that prompted community-building projects. To solve the vacant house issue, there has been rising interest in building communities through vacant houses as rural resources and effectively integrating them as useful resources. However, the roles of key entity that pursues community-building projects using vacant houses have not been discussed sufficiently. Thus, this study deals with the 'Vacant House Recreation Project of NPO Corporation in Onomichi' in Hiroshima, Japan. Through the case study, the following are introduced as NPO's roles in community-building projects using vacant houses. First, pursuing promotion and attracting attention by making the utilization of vacant houses sensational; system improvement; offering information. Second, enhancing the perception of local residents by offering local services using vacant houses; offering community-building items. Third, forming a place of public discussion to solve conflicts during community-building projects using vacant houses; offering alternatives to building communities. Above all, such roles have led to the key status of NPO during its community-building projects using vacant houses. It offers the following implication for Korea: Future vacant house-related policies for rural revitalization should be done from community-building standpoint and include establishing the roles of NPO.

The retinal degenerative disease, progressive retinal atrophy (PRA) is a major reason of vision impairment in canine population. Canine PRA signifies an inherently dissimilar category of retinal dystrophies which has solid resemblances to human retinis pigmentosa. Even though much is known about the biology of PRA, the knowledge about the intricate connection among genetic loci, genes and pathways associated to this disease in dogs are still remain unknown. Therefore, we have performed a genome wide association study (GWAS) to identify susceptibility single nucleotide polymorphisms (SNPs) of PRA. The GWAS was performed using a case-control based association analysis method on PRA dataset of 129 dogs and 135,553 markers. Further, the gene-set and pathway analysis were conducted in this study. A total of 1,114 markers associations with PRA trait at p < 0.01 were extracted and mapped to 640 unique genes, and then selected significant (p < 0.05) enriched 35 gene ontology (GO) terms and 5 Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways contain these genes. In particular, apoptosis process, homophilic cell adhesion, calcium ion binding, and endoplasmic reticulum GO terms as well as pathways related to focal adhesion, cyclic guanosine monophosphate)-protein kinase G signaling, and axon guidance were more likely associated to the PRA disease in dogs. These data could provide new insight for further research on identification of potential genes and causative pathways for PRA in dogs.

Pectobacterium odoriferum is the primary causative agent in Kimchi cabbage soft-rot diseases. The pathogenic bacteria Pectobacterium genera are responsible for significant yield losses in crops. However, P. odoriferum shares a vast range of hosts with P. carotovorum, P. versatile, and P. brasiliense, and has similar biochemical, phenotypic, and genetic characteristics to these species. Therefore, it is essential to develop a P. odoriferumspecific diagnostic method for soft-rot disease because of the complicated diagnostic process and management as described above. Therefore, in this study, to select P. odoriferum-specific genes, species-specific genes were selected using the data of the P. odoriferum JK2.1 whole genome and similar bacterial species registered with NCBI. Thereafter, the specificity of the selected gene was tested through blast analysis. We identified novel species-specific genes to detect and quantify targeted P. odoriferum and designed specific primer sets targeting HAD family hydrolases. It was confirmed that the selected primer set formed a specific amplicon of 360 bp only in the DNA of P. odoriferum using 29 Pectobacterium species and related species. Furthermore, the population density of P. odoriferum can be estimated without genomic DNA extraction through SYBR Green-based real-time quantitative PCR using a primer set in plants. As a result, the newly developed diagnostic method enables rapid and accurate diagnosis and continuous monitoring of soft-rot disease in Kimchi cabbage without additional procedures from the plant tissue.

The general objective of this research is to study behavioral pattern of health care utilization and to measure the level of utilization of the traditional medicine. The specific objective is to study utilization pattern and content of folk medicine which is the indegenous medical technology recognized part of traditional medicine. This research was under taken to generate valid information that will provide basis data for formulating general direction for health education activities and for designing service package for general population. A social survey method was employed to obtain required information for the research activities, The survey field team consisted of 20 surveyors who all participated is an intensive 2 day training course. A total of 3091 households were visited and interviewed by the field team during the period 7 September to 6 October 1987. The major findings obtained from the information collected by the field survey are as follows ; 1) General characteristics of the study households 2562 households out of 3091 households visited were selected for final data process, 80.2 of the selected households were nuclear families ; 17.4%, extended families ; others 2.4%. Only 4.3 percent of the study population in the urban households indicated "no schooling" whereas 14.2% of the rural household members falls within this category. Study population in the urban areas are more protected against diseases by the national medical insurance system than those in rural areas. In their self appraisal of living standard, those who responded with low group are 39.6% and 50.3% respectively by urban and rural households. 2) Morbidity status Period prevalence rate for all diseases during the preceding 15 days before the date of the household interview v as 243,0 per 1,000 study population. For cases with the illness duration of within 15 days, the initial points of medical entry were diversied ; 56.9%, drug stores ; 30.9%, clinics and hospitals ; 4.6% folk medicine ; 1.7% clinics of Korean oriental medicine. Among the chronic case; with illness duration of over 90 days, 34.6% of these people utilized clinics and hospitals of modern medicine ; 31.6%, drug stores ; 18.6% clinics of Korean oriental medicine ; 6.8% folk medical techniques. Noticeable is the almost ten fold increase from the mere 0.9% in the utilization of Korean oriental medicine, whereas in the utilization of folk medicine, it is short of two-fold increase. 3) Folk medicine and its utilization Households that use folk medicine for relief and care of signs and symptoms commonly encountered in daily life, number 1969 households, which accounts for 76.9% of all the study households. This rather high level use of folk medicine is not different from rural to urban areas. The order of frequency of utilizing folk medicine among the study people are : the highest 14.3% for the relief of indigestion ; 8.6% for burns ; 5.1% for common cold ; 4.7% for hiccough ; and 4.2% for hordeolum. A present various procedures of folk medicine is being used to relieve all kinds of symptoms. 192 symptoms are identified at present. The most frequently used procedures of folk medicine appear to be based either on principles of the Korean oriental medicine or of scientific knowledge. Based on these survey findings, proposals for utilizing folk medicine are as follows First, this survey's findings will be feed back to both on the job training and on the spot guidance of community health practitioners, public health nurses and other peripheral work force in the health field, who are in daily contacts with community. This feed back will assure that the health personnel carry out their health education and information activities that are based on the utilization pattern of folk medicine as found in the survey result. Second, studies will be soon implemented that are designed to measure the efficiency and potency of these procedures and to improve these procedures of folk medicine were most frequently used by the community. Third, studies will continue to systematize medicinal plants and skills of Korean oriental medicine that are easily available at minimal cost in daily life for the prevention of diseases and management of emergency cases.

Objectives : Cancer is the second most frequent cause of death in Korea. Cancer screening tests can save lives through early detection. Enhancing the cancer screening rate is an important strategy for reducing cancer mortality. The purpose of our study was to evaluate the screening rate and related factors in a rural area. The study investigated relationships between sociodemographic characteristics, several preventive behaviors, and the experience of several cancer screening behaviors. Materials and Methods : The study population was recruited voluntarily from the three rural areas(Myen) in Chungju city. The participants completed structured questionnaire from July 21, 1990 to July 26, 1998. Results : The proportions of the study population who had previously received stomach, liver, breast, or cervix cancer screening tests were 24.5%, 18.5%, 27.0%, 59.2% respectively. The 1-year screening rates of stomach, liver, breast, and cervix cancer were 7.4%, 6.8%, 8.6%, 15.6% respectively. In multivariate logistic analysis, some sociodemographic variables, preventive behaviors, or psychological variables were significantly associated with several cancer screening tests. Those who had previously received a stomach cancer screening test were significantly associated with the presence of chronic disease, physician's recommendation, use of alcohol family history of cancer, or previous liver cancer screening test. Those who had previously received a liver cancer screening test were associated with education level, physician's recommendation and previous stomach cancer screening test. Those who had received a cervix cancer screening test were significantly associated with education level, presence of a transportation vehicle, physician's recommendation use of alcohol and previous breast cancer screening test. And those who had received a previous breast cancer screening test were significantly associated with age, marital status, and earlier cervix cancer screening test. Conclusion : Based on the results of this study a strategy to promote cancer screening and health objectives at the district level can be made.

At present, the elderly population in Korea is 14% of the total population and then We has entered an the society of advanced age. Along with this, elderly people with dementia and palsy are also increasing. The demand for elderly nursing homes for elderly people with severe diseases such as dementia and stroke is also increasing, and the existing buildings are being secured by Conversion of existing buildings. However, it is difficult to evacuate and fire due to the out of date of buildings by Conversion of existing buildings. For example, there is a fire in the Indukukwon, Pohang City and Hyosung Geriatric Hospital, Jangseong in Korea, which have changed the use of existing buildings. Many elderly people died in a night fire. It was because of the sandwich panel walls and PVC flooring material produced toxic gas instantly. In this study, we investigated the nursing home that changing the use and established fire prevention of human injury and countermeasure of evacuation. First, the sandwich panels which leading to deaths due to the toxic gas were installed in most nursing home. We recommend the RC, the masonry wall, and the glass fiber panel instead of the sandwich panels, In addition, the PVC flooring is most used in nursing home, the flooring material is considered such as the building stones, the tile, and the yellow soil closing instead of the PVC flooring. Second, we investigated the installation status of fire fighting equipment. As a result, the automatic-emergency open&shut equipment, the smoke ventilator and the evacuation slide were rarely installed. In order to secure the golden time in case of fire and to prevent the asphyxia caused by the toxic gas, the law should be amended to install the equipment.

Objective: To estimate the incidence and mortality rates for pancreatic cancer in China. Methods: After checking and reviewing the cancer registry data in 2009 from 72 cancer registry centers, we divided cancer registry areas into urban and rural areas. Incidence/mortality rates, age-specific incidence/mortality rates, age-standardized incidence/mortality rates, proportions, and cumulative incidence/mortality rates for pancreatic cancer were calculated. Results: The total number of newly diagnosed pancreatic cancer cases and deaths in 2009 were 6,220 and 5,650, respectively. The crude incidence rate in all cancer registry areas was 7.28/100,000 (males 8.24, females 6.29). The age-standardized incidence rate by Chinese standard population (ASR) was 3.35/100,000, with ranking at 7th among all cancers. Pancreatic cancer incidence rate was 8.19/100,000 in urban areas whereas it was 5.41/100 000 in rural areas. Cancer mortality rate in all cancer registry areas was 6.61/100,000 (males 7.45; females 5.75), with ranking at 6th among all cancers, and 7.42/100 000 in urban but 4.94/100000 in rural areas. Conclusions: Pancreatic cancer incidence and mortality rates have shown a gradual increase in China. Owing to the difficulty of early diagnosis, identification of high-risk population and modification of risk factors are important to reduce the burden of pancreatic cancer.
