도시의 쇠퇴를 판단하고자 하는 다양한 연구가 진행되었지만 대부분의 연구에서는 쇠퇴도시의 일반적인 특성을 활용하여 보편적인 수준에서의 도시쇠퇴를 분석하였다. 하지만 도시의 쇠퇴는 특정 도시의 고유한 특성에 기반하여 발생하기 때문에 이를 고려해야한다. 또한 도시쇠퇴는 미세 공간에서 발생하고 확산하는 양상을 보이기 때문에 작은 단위의 공간을 연속적으로 분석해야한다. 본 연구는 울산광역시를 대상으로 지역적 특성을 고려한 도시쇠퇴 측정 모델을 개발하고, 이를 활용하여 울산광역시의 도시쇠퇴를 시간적·공간적으로 분석하는 것을 목적으로 한다. 지역적 특성을 모델에 반영하기 위하여 전국 평균대비 울산광역시의 지표값을 계산하여 이를 가중치에 반영한다. 또한 행정동 단위로 도시쇠퇴를 분석한 후 보다 작은 단위 공간에 대한 분석을 수행하기 위하여 공간적 계층구조를 활용해 집계구 단위로 도시쇠퇴를 분석한다. 모델을 활용하여 산출된 지수와 울산광역시의 사회현상을 연관지어 도시쇠퇴 패턴을 분석한 결과 도시쇠퇴가 군집을 이루며 시간이 흐를수록 인접지역으로 확산하는 형태를 보였다. 또한 신도심의 발생, 도시재생사업 등 도시 외적인 요소가 도시쇠퇴에 영향을 주고 있음을 확인하였다. 본 연구에서 활용한 도시쇠퇴측정모델을 통해 도시의 쇠퇴와 심각도를 파악함으로써 도시재생사업 필요지역의 우선순위를 제시할 수 있을 뿐만 아니라 진행중이거나 완료된 도시재생사업의 효과를 검정할 수 있다.

1. Objectives The purpose of this study is to find out effects of Hyeongbangpaedok-san(HBPDS) and Dokhwaljihwang(DHJH) against decline of physical function as aging. 2. Methods Administrating HBPDS and DHJH to 40-week-old Wistar rat for 10 weeks so, I researched weight change, weight change of internal organs, and hematological and serological changes. 3. Results & Conclusions 1. Both examining groups, which were taken HBPDS and DHJH, got more weight than control group. But that was regardless. 2. Both examining groups got more weight on internal organs than control group. But that was regardless, too. 3. Both examining groups decreased in amount of MDA in serum, as contrasted with control group. But it was regardless. 4. Both examining groups improved on hematological condition. WBC, RBC, Hgb, monocytes and eosinophil rates were decreasing and HCT and PLT were increasing. Especially monocytes(p<0.001) and eosinophil(p<0.05) rate of DHJH taken group was decreased remarkably. 5-1. Both examining groups show decline in each item of functional examination of liver, such as ALT, AST, T-bilirubin, T-protein, ALB, A/G. T-chol, TG, etc. HBPDS taken group showed meaningful decline in Albumin(p<0.01) and A/G(p<0.01) and DHJH taken group showed meaningful decline in T-bilirubin(p<0.01). 5-2. Both examining groups showed decline in items of functional examination of kidneys. Specially HBPDS taken group showed meaningful decline in CRN rate(p<0.05) and DHJH taken group showed meaningful decline in BUN rate(p<0.05). As those results, HBPDS and DHJH are effective against decline of physical function as aging.

Background & objectives: Cognitive function decline is a main factor influencing the overall life of the elderly and places a burden of society. The aime of this study was to investigate the risk factors of cognitive function decline of elderly living alone and living with a spouse. Methods: This study used the Korean Longitudinal Study of Ageing from 2014 to 2018. 243 older adults who lived alone and 1,155 lived with a spouse with the Korean version of Mini Mental State Examination scores in normal range at the time of 2014 were included in the analysis. Logistic regression analysis was conducted to determine the difference of risk factors affecting cognitive function decline between in elderly living alone and elderly living with a spouse. Results: Cognitive function decline incidence rate of elderly living alone was 30.5% and the elderly living with a spouse showed 23.0%. According to the results of logistic regression analysis, the risk factors of cognitive function decline in the elderly living alone was age and residential area, while in the elderly living with a spouse were age, education level, social networks, and depression. Conclusions: The factors that affect the cognitive function decline of the elderly living alone and the elderly living with a spouse were different. Accordingly, other measures to prevent cognitive decline are necessary.

Background: The purpose of this study is to identify the factors infecting the medical care utilization from a new perspective by newly classifying the categories of administrative districts using the urban decline index and medical vulnerability index as indicators. Methods: This study targeted 150,940 people who used medical services using the 2015 cohort database (DB), 2010-2015 urban regeneration analysis index DB, and 2014-2015 public health and medical statistics DB. The decline of the region was classified using the urban decline index typed using k-means clustering and the medical vulnerability index typed using the quantile score calculation. Regression analysis was performed 3 times with medical expenditure, length of stay, and the number of outpatient visits as dependent variables. Results: There were 37 stable region (47.4%), 29 health vulnerable region (37.2%), and 12 decline region (15.4%). The health vulnerable region had lower medical expenditure, fewer outpatient visits, and a higher length of stay than the stable region. The decline region was all higher than the stable region but had no significant effect. Conclusion: The factors that cause the health disparity between regions are not only factors related to individual health behavior but also environmental factors of the local community. Therefore, there is a need for a systematic alternative that properly considers the resources within the community and reflects the characteristics of the population.

본 연구는 도시쇠퇴가 주민의 주관적 삶의 만족감에 미치는 영향을 실증하였다. 실증분석을 위하여 우리나라 도시들을 규모별로 분류하고, 각각의 도시규모별 쇠퇴정도에 따른 전반적 생활만족감, 가족의 수입만족감, 주거환경 만족감으로 구분하여 살펴보았다. 도시쇠퇴의 진행과 삶의 만족감 변화의 동태적 관계를 규명하기 위하여 한국노동패널(KLIPS) 자료를 사용하여 고정효과모형(Fixed effect model)을 사용하였다. 분석결과 도시쇠퇴가 주민의 삶의 만족감에 미치는 영향은 거주하는 도시의 규모에 따라, 부문별 삶의 만족감에 따라 각기 다르게 나타나고 있다. 대도시 주민의 경우 도시쇠퇴가 진행됨에 따라 주거환경 만족감은 감소하나, 과밀 해소로 인한 사회적비용의 감소로 전반적 생활만족감은 증가하였다. 이와 달리 소도시 주민의 경우에는 도시의 쇠퇴가 전반적 삶의 만족감, 가족의 수입만족감, 주거환경만족감을 모두 감소시키는 것으로 확인되었다.

The effects of type (high and low voltages) and time (3, 40 and 60 min postmortem) of stimulation on drip loss and meat color at 24 h post-mortem were determined on M. longissimus dorsi of 38 crossbred steers and heifers. In addition, the effect of pH early postmortem (70 min postmortem) on the rate and extend of meat tenderization was examined. Either high or low voltage stimulation at 3 min showed a tendency for faster pH decline (p=0.052) and higher drip loss (p=0.08), and improved the color dimensions of L*, a* and b* (p<0.01), compared to stimulation at 40 min. This was equivalent to approximately one unit of an AUSMEAT color chip. On the other hand, although there were significant differences in pH decline between high voltage stimulation at 40 and 60 min, and between low voltage stimulation at 40 min and control sides, drip loss and meat color did not differ significantly (p>0.05). The results suggested that early application of stimulation, regardless of type of stimulation, improved overall meat color at 24 h postmortem through its effect on faster glycolysing rate. However, if the pH decline was moderate, the benefit of electrical stimulation on meat color was not apparent. An intermediate pH decline resulted in the lowest shear force. Due to differential ageing rates the optimum pH at 70 min postmortem increased with ageing time from 5.96, 6.07, 6.12 and 6.14 for 1, 3, 7 and 14 days postmortem, respectively. This implied that a small difference in the rate of pH decline was important, especially carcasses stimulated for very early postmortem, and the optimum rate of pH decline varied with intended ageing period. The study suggests that the beneficial or adverse effects of electrical stimulation on drip loss, meat color and tenderness is determined by the rate of pH decline, rather than by stimulation treatment and time of application per se.

The aim of this study is to suggest the quantitative standard of a marginal village. For the purpose, the study selected 43 villages with the population of 50 or less, the classification of a marginal village in accordance with advanced research and 47 villages with the population over 50 in Buyeo-gun region. The common reason of occurrence of a marginal village suggested by advanced research is a characteristic of a village or decline and extinction of a village rather than a simple index of population or aging rate. Therefore, the study assumed that decline of functions of the village would be caused by decline a function of communities consisting of the villagers. The study then assumed that the relatively low or 0 number or rate of participants would result in community functions. The study conducted t-test on basis of population and aging rate and an analysis to find the range with relatively large differences in the number of communities, participants and the rate of the participants, etc. The result showed that the community function began to decline when the population was less than 60~70 and the aging rate over 75%~85%. As the decline of functions of communities began in population of 70, the critical point was met when the population was 40 or less. With population of 40 or less, the young and the old group communities became extinct or showed rapid decrease in the number of participants. The study assumed that decline of functions of a village, a reason of occurrence of a marginal village would be decline of functions of communities, but there was no further analysis on decline or extinction of a village with population of 40 or less. There shall be further studies about whether a village of population of 40 or less is led to decline of a function or extinction of village communities.

본격적인 인구감소 시대에 들어선 가운데 지방 도시들은 사회적 인구 유입도 어려운 상황을 고려하여 생활인구 유도를 통한 도시 활력 증진을 모색할 필요가 있다. 본 연구는 이동통신 빅데이터를 활용한 도시활력도 분석을 위해 인구감소 지역인 부산광역시 행정동을 대상으로 주민등록인구와 생활인구의 시공간 분포특성을 비교하였다. 다음으로 행정동을 인구증감의 변화 양상으로 유형화한 후, 도시쇠퇴 및 활력 관련 지표를 사용하여 유형별 지역 특성을 분석하였다. 시공간 분포특성 분석결과, 주민등록인구와 생활인구 밀도 분포패턴은 대체로 비슷한 패턴을 보였으나, 원도심 지역에서 주민등록인구 밀도가 낮으면서 생활인구 밀도가 높은 반대의 특성을 가지는 지역이 나타났다. 주민등록인구와 생활인구의 변화 양상은 상당한 차이를 보였으며, 주민등록인구는 밀도가 낮은 지역에서 인구가 감소하는 반면, 생활인구는 밀도가 높은 지역에서 감소하는 경향을 보였다. 생활인구 감소 군집에 인접해서 인구증감의 지역 간 격자가 큰 군집이 나타나, 인구 밀도가 높은 지역에서 주변 지역에 생활인구가 확산하는 전이효과가 나타날 가능성을 시사했다. 유형화 결과, 주민등록인구가 감소하는 지역에서도 통근·통학 또는 방문으로 인한 활발한 인구 유입이 있었으며, 이러한 지역은 사업체 수의 증가를 유지하고 있어, 산업·경제적 성장이 존재함을 확인하였다. 다만 부산의 약 47% 행정동은 주민등록인구와 생활인구가 모두 감소하고 지역 쇠퇴가 진행되고 있었으며, 이러한 지역에 대해 우선적인 도시 활력 증진을 위한 노력이 필요하다. 본 연구는 교통과 통신의 발달로 인한 도시활동의 한계거리 증가와 이동량의 증가로 지역간 교류가 날로 확대되는 점을 고려해 주민등록인구뿐만 아니라 도시계획지표로서의 생활인구 데이터의 활용 필요성을 제시하였다.

This article assumes that the first newtown has declined in Korea. Urban regeneration projects should be implemented for regeneration for CBD in Newtown as well as small local cities. The purpose of this article is to analyze the character of the subway area and to suggest the key issues for regeneartion in the subway area. Especially focussing on the local important commercial function in 5 subway areas. As a result of analyzing 5 subway areas according to basic statistical data, field interviews, and legal decline diagnostic index, all five commercial districts showed decline. In particular, the decline of Baekseok Station area appears to be serious, and there is a key factor that attracts the decline of the commercial area such as the long - term building or the closure rate of each commercial area. In addition, the vacancy rate is increasing due to large distribution facilities in new cities, the entry of new floating facilities on the outskirts, and unsold new stores, and the recession is accelerating. In this way, the signs of decline in the core of the new city are enriched, but the current Urban Regeneration Act is a legal system with a policy goal of regeneration of small and medium cities in the provinces as a system to promote the function of core bases rather than the overall redevelopment of new cities. Therefore, preemptive response is needed for the regeneration in those areas.
