  • 1990년대 이후 한국 경제는 두 번의 금융위기(1997년 아시아 금융위기와 2008년 글로벌 금융위기)를 겪었다. 이들 금융위기는 한국 실물경제의 여러 지표에 영향을 끼쳤고 이로 인해 한국의 최대 수출입 관문인 부산항에서 처리되는 물동량 변화에도 영향을 주었다. 그러나 아시아 금융위기 당시 부산항의 총 컨테이너처리실적을 살펴보면 금융위기와 관련된 영향이 명백히 나타나고 있지 않다. 이 연구는 이들 금융위기가 부산항 물동량 변화에 끼친 영향을 분석하기 위해 ARIMA모형의 특수한 형태 중 하나인 개입모형을 이용하였다. 개입모형은 시계열 예측뿐만 아니라 특정 사건발생과 관련된 그 효과를 분석하기 위하여 사용되는 정량적 모형으로 이 연구에서는 개입효과의 추정에 중점을 두었다. 그 결과 부산항 물동량 변화에 두 번의 금융위기가 유의미한 영향을 미쳤다는 것을 보였다.

  • This study aimed to investigate effect of scalp acupuncture (SA) and repetitive transcranial magnetic stimulation (rTMS) intervention on neuromotor function in photothrombotic cerebral infarction (PCI) rat model. Sixty male SD rats were used. PCI was induced on M1 cortex of right frontal lobe. SA was performed at the Qianding (GV21), Xuanli (GB6) acupoints of ipsilesional M1. Low-frequency rTMS was delivered to contralesional M1. All rats were randomly divided into 4 groups: group A, normal (n, 15); group B, PCI without any stimulation intervention (n, 15); group C, PCI with SA (n, 15); group D, PCI with rTMS (n, 15). Rota-rod test and Ladder rung walking test (LWT) were done weekly for 8 weeks after PCI. SA or rTMS was started from post-PCI 4th day as protocol for 8 weeks. H/E stain and IHC were done. Western blot and qRT-PCR study were performed for MAP2 and BDNF from ipsilesional M1 peri-infarction tissue. Brain MRI study was conducted to quantify the volume of cerebral infarction. As a result, left forelimb and hindlimb function significantly improved more in group C and D than control group, with expressed more BDNF and MAP2. And brain MRI showed focal infarction of right M1 after PCI, and infarction volume progressively decreased in group C and D than group B from post-PCI 5th to 8th week. SA or rTMS was more effective than no intervention group on neuromotor function of PCI rat model. The functional recovery was associated with stimulation intervention-related neurogenesis.

  • Purpose: This study was conducted to identify the effects of a lifestyle intervention program on weight gain, dietary habits, fatigue and pregnancy stress, blood pressure, and neonatal birth weight, using Cox's interaction model of client health behavior for overweight and obese women. Methods: This was a quasi-experimental research with a non-equivalent control group pre-post test design. A total of 52 patients who met the selection criteria, including 25 in the experimental group and 27 in the control group, were the subjects of the study; they comprised overweight and obese pregnant women who were receiving prenatal care at A and B women's hospital in J province. The lifestyle intervention program ran for 12 weeks in total and consisted of interactions involving affective support, health information, and professional/technical competencies. The data collection period was from February 1, 2017 to August 31, 2017. Results: This study showed differences in the appropriate weight gain rate (χ2=6.17, p=.013), suppression of an increase in fatigue (t=-2.32, p=.012), and an increase in pregnancy stress (t=-1.87, p=.034). Yet, no differences in physical activity, dietary habits change, blood pressure, and neonatal birth weight (p>.05) were found. Conclusion: The study findings indicate that this program could be an effective intervention for the control of appropriate weight gain, fatigue, and pregnancy stress. Therefore, a lifestyle intervention program based on Cox's interaction model of client health behavior could be an efficient strategy for a positive health outcome of overweight and obesity pregnant women.

  • Background: Effective policy implementation is essential for a healthy workplace. The Ryan-Kossek 2008 model for work-life policy adoption suggests that supervisors as gatekeepers between employer and employee need to know how to support and communicate benefit regulations. This article describes a workplace intervention on a national employee benefit, Family and Medical Leave Act (FMLA), and evaluates the effectiveness of the intervention on supervisor knowledge, awareness, and experience with FMLA. Methods: The intervention consisted of computer-based training (CBT) and a survey measuring awareness and experience with FMLA. The training was administered to 793 county government supervisors in the state of Oregon, USA. Results: More than 35% of supervisors reported no previous training on FMLA and the training pre-test revealed a lack of knowledge regarding benefit coverage and employer responsibilities. The CBT achieved: (1) a significant learning effect and large effect size of d = 2.0, (2) a positive reaction to the training and its design, and (3) evidence of increased knowledge and awareness regarding FMLA. Conclusion: CBT is an effective strategy to increase supervisors' knowledge and awareness to support policy implementation. The lack of supervisor training and knowledge of an important but complex employee benefit exposes a serious impediment to effective policy implementation and may lead to negative outcomes for the organization and the employee, supporting the Ryan-Kossek model. The results further demonstrate that long-time employees need supplementary training on complex workplace policies such as FMLA.

  • Purpose: To evaluate a reducing alcohol intervention program for workers. Method: The intervention program employed one-group pretest-post-test design with repeated measuring by quasi-experimental study. The program was developed from literature review based on the Transtheoretical Model, and evaluated from April 6 to June 22, 2006. Sixteen white collar male workers participated. At the beginning, the subjects were at the pre-contemplation stage (50%) and contemplation stage (50%). The intervention was applied personally or in group twice a week for 9 weeks. Results: The scores of each stage of change in the post-test increased significantly compared with those in the pretest. The scores of process (cognitive and behavioral) of change in the post-test increased significantly compared with those in the pretest. The score of self-efficacy of change in the post-test increased significantly compared with that in the pretest. The score of pros-cons for drinking in the post-test decreased significantly compared with that in the pretest. The consumption of alcohol a week and a day in the post-test decreased significantly compared with that in the pretest. The levels in ALT, AST, GGT, total cholesterol, triglyceride, B.P. and BMI in the post-test did not decrease significantly compared with those in the pretest, but the level of FBS decreased significantly compared with that in the pretest. Conclusion: The above result informs us that a stage-based reducing alcohol intervention program for workers has the effect of increasing the stages of change, the process of change (cognitive and behavioral) and self-efficacy, and decreasing pros-cons for drinking alcohol consumption and FBS, and it also has a value as an effective means of nursing for workers.

  • Objectives: Early intensive interventions are very important for children with autism spectrum disorder. We examined the actual conditions of hospital-based early intensive interventions for autism spectrum disorder in Seoul, in order to help develop and implement an evidence-based early intensive intervention model for use in Korea. Methods: Nine hospital-based institutes running an early intensive intervention program for children with autism spectrum disorder responded to a questionnaire in September 2014. They provided a brief introduction to their program, explained its theoretical bases, and reported the number of children, their age, intervention time, duration and so on. Results: In the majority of the institutions, the intervention was provided for over 20 hours every week, and the theoretical bases included various applied behavioral analysis (ABA) methods and other therapies (language and occupational therapy). The therapist-child ratio ranged from 1:1 to 5:3. Various types of therapists were involved, including behavioral analysts, special education teachers and (or) language pathologists. There was only one clinic where the behavioral analyst was the main therapist. Usually, the intervention was terminated just before the child entered elementary school. The main merit of the hospital-based intervention in our survey was the effectiveness of the multi-disciplinary intervention plan and its other merits were the accuracy of the diagnosis, its ability to be combined with medicine, and so on. Conclusion: The current hospital-based early intensive intervention programs provide interventions for over 20 hours per week and employ multidisciplinary approaches. However, there are very few institutes for children with autism and very few intervention specialists and specialist education courses in the country. We need more educational programs for intervention therapists and have to try to develop policies which encourage the implementation of an evidence-based early intensive intervention program nationwide.

  • This paper examines the usefulness of a Brake Steer System (BSS), which uses differential brake forces for steering intervention in the context of Intelligent Transportation Systems (ITS). In order to help the car to turn, a yaw moment can be achieved by altering the left/right and front/rear brake distribution. This resulting yaw moment on the vehicle affects lateral position thereby providing a limited steering function. The steering function achieved through BSS can then be used to control lateral position in an unintended road departure system. A 8-DOF nonlinear vehicle model including STI tire model will be validated using the equations of motion of the vehicle. Then a controller will be developed. This controller, which will be a PID controller tuned by Ziegler-Nichols, will be designed to explore BSS feasibility by modifying the brake distribution through the control of the yaw rate of the vehicle.
