도농복합시는 도시지역과 농촌지역이 병존하는 독특한 공간구조를 갖고 있다. 따라서 도농복합시의 농촌과소화에 대응하기 위해서는 기존 주민의 이탈을 방지할 수 있는 다양한 정책적 지원 방안을 모색할 필요가 있다. 이러한 맥락에서 본 연구에서는 '2017년 춘천시 사회조사'를 이용해 도농복합시 농촌지역 과소화 대응 방안으로 기존 거주민의 지속적인 거주의향에 영향을 미치는 요인을 분석하였다. 일반적으로 지역정체성은 내생적으로 결정되기 때문에 본 연구에서는 이러한 지역정체성과 거주의향과의 내생적 관계를 고려하여 연립 이변량 순위 프로빗 모델을 이용하였다. 분석결과, 도농복합시에 대해 지역정체성이 강할수록 지역내 거주의향이 높아지는 것으로 분석되었다. 가구주의 연령과 거주기간이 길수록, 일 여가생활 거주에 대해 만족할수록 지역정체성이 높다. 그리고 의료서비스에 대해 만족할수록, 종사하는 일에 만족할수록 거주의향이 높다. 따라서 도농복합시 농촌지역 거주민들의 생활서비스 수요를 파악 후 적재 적시 적절한 생활서비스를 공급할 수 있는 정책적 지원이 필요하다. 특히 도농복합시의 경우 의료서비스는 지역정체성에는 통계적으로 유의미한 영향을 미치지 않지만, 거주의향에는 유의미한 영향을 미치고 있다. 따라서 의료시설에 쉽게 접근하여 사용할 수 있는 시스템 구축이 필요하다.

This report describes the use of a transtubular bioreactor to study the relative effects of diffusion versus perfusion of medium on antibody production by a hybridoma cell line. The study was performed with a high-density cell culture maintained in a serum-free, low-protein medium for 77 days. It was determined that the reactor possessed a macro-mixing pattern residence time distribution similar to a continuous stirred tank reactor (CSTR), However, due to the arrangement of the medium lines in the reactor, the flow patterns for nutrient distribution consist of largely independent medium path lengths ranging from short to long. When operated with cyclic, reversing, transtubular medium flow, some regions of the reactor (with short residence times) are more accessible to medium than others (with long residence times). From this standpoint, the reactor can be divided into three regions: a captive volume, which consists of medium primarily delivered via diffusion; a lapped volume, which provides nutrients through unilateral convection; and a swept volume, which operates through bilateral convection. The relative sizes of these three volumes were modified experimentally by changing the period over which the direction of medium flow was reversed from 15 min (larger captive volume) to 9 h (larger swept volume). The results suggest that antibody concentration increases as the size of the diffusion-limited (captive) volume is increased to a maximum at around 30 min with a sharp decrease thereafter. As reflected by changes in measured consumption of glucose and production of lactate, no significant difference in cellular metabolism occurred as the reactor was moved between these different states. These results indicate that the mode of operation of the transtubular bioreactor may influence antibody productivity under serum-free, low-protein conditions with minimal effects on cellular metabolism.

The purpose of this study was to analyze adaptation for Korean foods and satisfaction for university foodservice by nationality and residence period of Chinese and Japanese university students in Daejeon, Republic of Korea. Among 330 questionnaires distributed to Chinese and Japanese students, 294 complete questionnaires (89.1%) were analyzed. The questionnaire included two 5-point scales for measuring levels adaptation of for Korean food and satisfaction with university foodservice, respectively. Japanese students' level of adaptation for Korean food (3.16) was significantly higher than that of Chinese students (2.96). As the length of residence in Korea increased, the frequency of using university lunch service per week significantly decreased. The main factor when selecting a menu item was food taste (39.8%, 22.8%) in both Chinese and Japanese students, whereas the next main factor was preference (16.4%) in Chinese students and nutrition (18.7%) in Japanese students. The preferred cooking methods for meat were stir-frying (31.6%) and roasting (25.9%). For fish, Chinese students preferred braising (32.7%), whereas Japanese students preferred roasting (26.8%). Both Chinese and Japanese students preferred sukchae (45.6%, 43.1%) for vegetables. Factor analysis grouped 17 items measuring university foodservice into four factors, 'sanitation & employee service', 'physical environment', 'food' and 'customized menu & information' and the mean scores were 3.56, 3.30, 3.20 and 3.00, respectively. Chinese students were significantly more satisfied than Japanese students with the 'physical environment', 'sanitation & employee service' and 'customized menu & information'. These results suggest that efforts such as developing a greater variety of menu items with mild tastes and somewhat less flavor, applying preferred cooking methods, offering special menus for foreign students, providing nutrition information on menus, and offering a description of menu items in the foreign languages could improve Chinese and Japanese students' levels of satisfaction with university foodservice.

The objective of this study was to clarify how distance from place of residence to the nearest specialist cancer hospital affects the survival of lung cancer patients and the treatment received. For all patients diagnosed with lung cancer in the Aomori cancer registry database for the period from 2009 to 2011 (n=3,986). The distance to the treating hospital was measured as the straight line from a person's place of residence, and compared with findings from the Ederer II method for calculating relative survival. Information on treatments given was obtained by data extraction. We defined a hospital having respiratory medicine as specialist, while all private hospitals and clinics were included in the general category. Patients attending specialist hospitals numbered 2,548 (67.0%), and those treated at general institutions were 1,255 (33.0%). The patients who had the lowest relative survival with localized lesions lived <20 km from general hospitals and clinics. With more advanced stages, relative survival of those living <20 km from a specialist hospital was the lowest. Although the survival rate was not affected by the distance between place of residence and hospital, even when patients are diagnosed at a localized stage at a general hospital or clinic within 20 km from their home, they did survive longer in comparison with patients diagnosed at a specialist hospital.

Vitamin mineral supplement usage by self-prescription is popular behavior among adolescents. This study was conducted to investigate the behaviors of vitamin·mineral supplement usage and the relationship between demographic variables and supplement usage by healthy adolescents. Nine hundred seventy two boys and girls, aged 13-18 years, attending general middle or high schools were chosen from various cities and rural communities in Korea. As a result, vitamin·]mineral supplements were taken by 31.3% of subjects. Users tended to take vitamin·mineral supplements more frequently when they were healthy than when they suffered from disease. The taking period of supplements was different according to school type such as middle or high school(p<.05), sex(p<.001) and residence of subjects(p<.01). The main information source of supplements was newspaper/magazine/TV, and it was affected by sex(p<.05) and residence(p<.01). Vitamin·mineral supplements were generally recommended by their mothers instead of health professionals. The commonly cited taking reason of supplements was affected by sex(p<.01)and socioeconomic status of family(p<.05). The frequently responded effect obtained from supplement use was recovery from fatigue and it was different according to sex(p<.01). The major mentioned reason of not taking vitamin·mineral supplements by non-users was 'I eat a balanced diet'. The most frequently consumed supplements were vitamin C, followed by multi-vitamins supplements, and this pattern was different according to school type(p<.001), sex(p<.01) and residence(p<.05). These findings show that the behaviors of vitamin·mineral supplement usage by subjects are not resonable, and their supplement usage tends to be affected by demographic variables. Therefore, nutritional understanding and education that are intended to form the resonable behaviors toward vitamin·mineral supplement usage of adolescents should be provided with considering the relationship between demographic variables and supplement usage.

This study has the purpose to reveal the differences of residents' using behaviors of living facilities at 3 complexes. The physical characteristics of the complexes have been investigated by a literature study and field survey. In addition, questionnaires were answered by residents on living facilities using behavior on community environment. The tools of analysis are frequency, percentage, and cross tabulation using SPSS WIN 12.0 program. Followings are the results of the study. 1) The developmental concept of 3 complexes maintained its initial identity. (1) The residence-oriented complex, having wider residential space, had better downtown access and more convenient facilities for daily life. (2) The residence-government mixed complex, constructed with an eco-friendly concept, had wider green and public service space and good downtown access but on the other hand, had less convenience facilities because of a short period from construction. (3) The residence-industry mixed complex, located in sub-urbanity and conceding more land for industries, had poor access to downtown but had more convenient facilities for workers' use. 2) The most frequently visited convenience facilities were shopping facilities, large or small, and banks, and activities were commonly done in the complex or adjacent area. This means it is recommended that the developer of the new complex locate convenience facilities in multi-core concentration types or street types rather than one-core concentration types.

체류시간이 서로 다른 두 부영양 수계에서 미소먹이망의 생태학적 정보를 파악하고자, 기초적 환경요인과 bacterioplankton 및 nanoplankton의 현존량 및 탄소생체량을 각각 조사하였다. 조사기간동안 두 수계 공히 강우는 주로 7월에서 9월에 집중하였으며, 수온 역시 큰 차이는 없었다. 두 수계의 플랑크톤 군집은 공히 저온기 동안에는 비교적 세포크기가 큰 nanoplankton이 우점한 반면, 고온기 동안에는 소형 bacterioplankton이 높은 현존량을 나타냈다. 그러나 비교적 수계가 안정된 석촌호수에서는 강우에 큰 영향을 받지 않은 반면, 경안천에서 nanoplankton은 현존량은 물론 탄소생체량의 다양한 변화를 보였다. 두 수계의 미세먹이망은 석촌호수에서는 박테리아와 phytoplankton 또는 cyanobacteria간에 밀접한 분포 관계를 보인 반면, 경안천에서는 박테리아와 protist 사이에 뚜렷한 먹이관계를 보였다. 또한 경안천에서 개체수와 탄소생체량간의 비대칭적인 현상이 뚜렷하였다. 따라서 경안천의 미세먹이망은 수온이나 영양물질보다 강우에 의한 빠른 체류시간에 의해 강하게 영향을 받고 있지만, 안정된 수계에 비해 bacterioplankton보다 nanoplankton들의 높은 성장과 종 다양성을 유도하였다.

In this study, indoor VOCs concentration emitted from floor and furniture was measured after the installation of floor and furniture in a real residence. With the measured data, prediction method and predication equations for indoor concentration of each VOCs and BTEX were developed. The following conclusions were drawn from this study. First, according to the predicted results of concentration decrease of BTEX (benzene, toluene, ethylbenzene, m,p,o-xylene) after the installation of floor in a real residence, prediction equation can be expressed using exponential function. Second, in case of floor, more reliable prediction equation can be obtained by using cumulative value of indoor concentration than by using just hourly measured value directly. Indoor concentration of benzene can be expressed as $y=408.52(1­e^{-00031{\times}time})$ with $R^2$ of 0.94 which is significantly high value. Third, toluene showed the highest concentration in case of furniture installation indoors, and it needed the longest time for concentration decrease. However, other substances except toluene showed constant concentration throughout the measurement period. Fourth, in case of furniture installation indoors, prediction equation of toluene concentration decrease is estimated to be $y= 3616.3{\times}e^{(-0.1091{\times}time)}+513.96{\times}e^{(-0.0006{\times}time)}\;with\; R^2$ of 0.95 which is significantly high value.
