This study investigated the conceptualization and application of new concept of regional resilience with case study in Korea in order to promote more sustainable regional development strategies, while problematizing dominant regional competitiveness concept in the current regional development circle under the condition of stagnant growth and ever-existing crisis in these days. Through literature review, this paper found out that regional resilience is a useful concept both to understand dramatic regional changes and to promote new regional development strategies. Furthermore, the study formulated basic research topics and issues for regional resilience through reviewing existing research outcomes on the measurement and factors of regional resilience. Through case study of two macro city-regions in Korea, this study also found out that regional resilience patterns and processes are differentiated according to the place and its scale and that both regional industrial structure formed in a path-dependent way and regional competitive characteristics are all significant to understand the regional resilience patterns and processes.

This study examined two differences in physical and psychological recovery patterns after surgery in the elderly. The sample consisted of 40 patients with abdominal surgery In five large hospitals in Seoul. The data for this study were collected from Apr. 20 to Nov. 26 by structured questionnaire, chart review and call. Physical recovery was assessed by ADL, a Cantril Ladder Scale and a Visual Analogue Scale. Psychological recovery was measured by the Geriatric depression Scale and a Cantril Ladder Scale. The data were analyzed using frequency, percentage, Pearson Correlation Coefficient, and MANOVA by SPSS/WIN. The result are as follows : 1. Physical recovery indicated significant improvement over time with the exception of ADL(F=.812 p=.449). Perceived physical health were significantly improved(F=6.189 p=.004). Pain & discomfort was significantly decreased(F=3.927 p=.025). 2. Perceived psychological health was significantly improved over time(F=20.648 p=.000), but depression showed no statistical significance improvement over time(F=1.393 p=.256). 3. There were no significant effects of sex, age, complication and combined chronic diseases on physical and psychological recovery patterns. 4. There were significant correlations between operation time and pain(r=-.331 p=.020), recovery time and perceived psychological health(r=-.320 p=.024), recovery time and pain(r=.404 p=.005). There were significant correlations between admision period and ADL(r=-.418 p=.004), perceived physical health(r=-.354 p=.014), depression(r=.280 p=.042), and perceived psychological health(r=-.447 p=.002). BRAS showed significant correlation with ADL(r=-.458 p=.002). 5. With an increase in the degree of perceived health(physical and psychological), ADL was significantly increased. With an increased in the degree of depression and pain, ADL and perceived health(physical and psychological) were significantly decreased. In conclusion, the elderly patient recovered significantly over time with the exception of ADL and depression. It these we suggested to considered when planning care for elderly patients.

The purpose of this study is to examine the effects of job stress and resilience on burnout of nurses who take care of patients with COVID-19 in prolonged pandemics. Structured questionnaires were distributed and analyzed for 162 nurses. Inadequate compensation of job stress, job demands, workplace culture, philosophical patterns of resilience, and relational patterns were statistically significant. As a result of determining the effect of job stress and resilience on burnout through the Stepwise multiple regression analysis, the final significant variable was job stress. The burnout of nurses can affect the quality of nursing services, reduced hospital competitiveness, and even quarantine systems. Therefore, this study suggests that proper compensation policy support, such as treatment of nurses and improvement of working conditions, is needed.

Magnetic domain structure and static magnetic properties were investigated in the ultra thin 3%Si-Fe strip wound cores when the strips were wound and annealed to relief the stress. The elastic and plastic deformation due to the radius of curvature was also investigated for the cores. At the as-wound state, the maze pattern domain structure was generated on the concave surface of the core and 180$^{\circ}$ domain wall was recovered by annealing 600 $^{\circ}C$$\times$30 min. After annealed by 900 $^{\circ}C$$\times$30 min, Hc of strip-wound cores was not reached to the $H_c$ of the strip even at the cores of elastic deformation region. It is necessary to relief the local stress remained in the core when the cores were manufactured for the application of ultra-thin 3%Si-Fe strip.

The purpose of this study is to discover the context and pattern of turnover social workers have experienced. To achieve this purpose, researchers collected data from in-depth interviews with seven social workers who have experiences of turnover and analysed the data using context-pattern analysis method. Research findings are composed of individual context-pattern analysis and integrated context-pattern analysis. In individual context-pattern analysis, researchers mixed time-dimension(before turnover/on the process/after turnover) and level-dimension(experienced phenomenon/meaning of experiences/context connected with phenomenon and meaning) and analysed the context of every stages and serial pattern. Also, we connected with each contexts and patterns and integrated the context-pattern of turnover. Integrated context-pattern structure is divided for four areas; organization before turnover, organization after turnover, social worker as a stakeholder of turnover, and network of social worker. Based on the results of the study, administrative recommendations were suggested in order to manage the turnover of social workers in social work fields.

The 2020 summer extreme flood severely disturbed the riparian ecosystem of the Seomjin River. Some trees were killed by the flood impact, whereas others have recovered through epicormic regeneration after the disturbance. At the same time, several tree individuals newly germinated. This research aimed to explain the recovery of the riparian ecosystem by spatial proximity between each tree individual of different characteristics, such as "dead", "recovered", and "newly germinated". A spatial point pattern analysis based on K and g-functions revealed that the newly germinated trees and the existing trees were distributed in the spatially clumping patterns. However, further detailed analysis revealed that the new trees were statistically less attracted to the recovered trees than the dead trees, implying competitive interactions hidden in the facilitative interactions. Habitat amelioration by the existing trees positively affected the growth of the new trees, while "living" existing trees were competing with the new trees for resources. This research is expected to provide new knowledge in this era of rapid climate change, which likely induces stronger and more frequent natural disturbance than before. Environmental factors have been widely used for ecosystem modeling, but species interactions, represented by the relative spatial distribution of plant individuals, are also valuable factors explaining ecosystem dynamics.

This paper proposes a restoration scheme based on mobility learning and prediction in the presence of the failure of mobility databases in mobile communication systems. In mobile communication systems, mobility databases must maintain the current location information of users to provide a fast connection for them. However, the failure of mobility databases may cause some location information to be lost. As a result, without an explicit restoration procedure, incoming calls to users may be rejected. Therefore, an explicit restoration scheme against the failure of mobility databases is needed to guarantee continuous service availability to users. Introducing mobility learning and prediction into the restoration process allows systems to locate users after a failure of mobility databases. In failure-free operations, the movement patterns of users are learned by a Neuro-Fuzzy Inference System (NFIS). After a failure, an inference process of the NFIS is initiated and the users' future location is predicted. This is used to locate lost users after a failure. This proposal differs from previous approaches using checkpoint because it does not need a backup process nor additional storage space to store checkpoint information. In addition, simulations show that our proposal can reduce the cost needed to restore the location records of lost users after a failure when compared to the checkpointing scheme

한반도 기후변화 경향은 이미 기상 생태 환경 수자원 등 광범위한 부분에서 감지되고 있다(기상청, 2011a, 2011b). 현재까지의 연구에 따르면 한반도 기후변화에 따른 영향으로 강우패턴은 첨두강우가 7월에서 점차 8월로 이동 변화하는 것으로 전망되고, 양적으로 연강수량은 점차 감소가 전망되면서도 극한 값은 발생빈도와 크기가 점증할 것으로 전망되고 있다. 그래서 그간 기존댐에 대한 재평가(1998, 2010, 2012)와 발생 가능한 최대강우량 설계기준으로 기존 댐의 여수로 배제 능력을 증대시키는 비상여수로 설치 등 기존 댐 시설위주의 효율적인 기후변화 대응 또는 적응 방안을 시행해 왔다. 그러나, 기후변화로 인한 기상 상황은 전에 발생한 적이 없었던 새로운 기상이변과 재난을 가져오고 있다. 이에 기상 변화에 하나의 시설로서 대응 하던 방식에서 한 번의 기상이변이 유역 전반에 걸쳐 재난을 발생하는 최근의 상황에 맞추어 수자원 시설을 계획하는 방식에 대한 변화의 필요성 있다고 생각하였다. 이에 장래 전망되는 기후변화를 감안하여 이수와 치수 시설의 가뭄과 홍수에 대한 대처 능력을 유역 차원에서 평가하는 방법을 찾아보고자 한다. Robust 하다는 것은 어떤 상황에서도 작동이 되는 것을 말하는 강건한 계획으로, 이와 같은 시설 계획을 위해서는 먼저 현재의 시설물에 대한 회복력을 판단하는 평가가 있어야 할 것이다. 따라서, 용수공급이든 홍수 재난이든 회복력(복원력)에 대한 평가를 하고, 대안에 대한 로버스트 의사 결정 방법(RDM: Robust Decision Making)을 적용하여 우수한 대안을 찾으면 강건한 시설계획 수립이라는 절차가 될 수 있다고 판단하였다. 본 연구는 회복력(복원력)을 갖는 로버스트 의사결정방법에 대한 과거 연구 조사를 기초로 하여 연구 수행 절차를 마련한 후에 장래 한반도 기후변화 시나리오를 시범 유역에 적용하여 수자원 시설의 복원 또는 회복력을 분석하고, robust 의사결정방법을 적용함으로써, 향후 로버스트 수자원 시설 계획이 어떻게 이루어져야 하는지와 함께 이수와 치수 시설의 종합적인 계획 등에 대한 개념적인 절차와 방법의 제시를 도모하였다.

말초신경은 외상이나 질병 등 여러 가지 원인으로 손상되기 쉬우며, 손상의 정도가 심하거나 치료가 지연되는 경우에는 심각한 기능 소실을 초래할 수 있다. 본 연구에서는 수영이 말초신경손상후 운동기능의 회복과 뇌유인성 신경영양인자 (brain-derived neurotrophic factor, BDNF) mRNA의 발현에 미치는 효과를 알아보기 위하여, 흰쥐 좌골신경에 압박 손상을 가하고 수영을 적용한 후 보행궤적분석 (walking track analysis)과 역전사연쇄반응 (reverse transcription-polymerase chain reaction, RT-PCR)을 실시하였다. 그 결과, 좌골신경 압박손상된 쥐는 특징적인 보행패턴을 나타내어 좌골신경기능지수 (sciatic function index, SFI)가 현저히 낮아졌으며, BDNF mRNA의 발현이 증가하였다. 좌골신경 압박 손상후 수영을 한 쥐에서는 SFI가 현저히 향상되었으며, BDNF mRNA의 발현은 억제되었다. 이러한 결과는 말초신경손상후 수영이 BDNF mRNA의 발현을 조절함으로써 기능 회복을 촉진시키는 효과적인 치료방법이 될 수 있음을 제안하고 있다.
