Recently, the container ships become fairly large so that the shipping capability is more than 10,000TED. Accordingly, very large ports are required and building such ports is extremely expensive. For this reason the mobile harbor concept has been proposed. The mobile harbor, which is located in a shallow sea, can replace a port that has insufficient infrastructure. Also, this system can alleviate congestion in the ports. The mobile harbor is a small container ship which has a container crane on it. The mobile harbor is a new innovative concept for moving containers from containership to a mobile harbor or vice versa. One of the most important basic technologies is the design of a crane structure for the mobile harbor. The crane for the mobile harbor is different from the conventional cranes on the ground. Stability is guaranteed on the ground, but is not so in the sea. This study examines structural optimization of the crane structure on the mobile harbor. The position of the boom of the crane is optimized as well. The design process considers the rolling and pitching conditions of the sea state and the wind force regulations from Korean Register of Shipping. Optimization problems are formulated to minimize the weight while various design conditions are satisfied, and the formulated problems are solved by a commercial software system called GENESIS.

Psychsocial factors appear to play an important role in the maintenance and development of chronic disability from low back pain. Fear of pain may be more disabling than the pain itself in patients with nonacute low back pain. The purpose of this study was to identify the contribution of gender, age, depression and pain-related fear to pain intensity and disability in nonacute low back pain patients. This was a cross-sectional survey study of eighty four patients who had low back pain for at least 4 weeks. More than moderate correlations were found between pain intensity, disability, fear-avoidance beliefs and depression. Regression analyses revealed that disability ratings and fear-avoidance beliefs for work activities significantly contributed to the prediction of pain intensity, even when controlling for age, gender and pain duration. Also, fear-avoidance beliefs for physical activity, pain intensity, age and depression, significantly contributed to the prediction of disability, even when controlling for gender and pain duration. These findings suggest that disability scores and fear-avoidance beliefs for work activities are important determinants of pain intensity. They also suggest that fear-avoidance beliefs for physical activity, pain intensity, age and depression are important determinants of disability.

Purpose: This study aimed to investigate the effects of an abdominal drawing-in maneuver (ADIM) with a light load while sitting on transverse abdominis contraction in subjects with and without low back pain. Methods: In this study, 20 participants with chronic low back pain and 20 controls participated. Ultrasonography was used to assess the thickness of the external oblique (EO), internal oblique (IO), and transversus abdominis (TrA) muscles. Muscle thickness was measured at rest and during ADIM in three different sitting postures: (1) just sitting, (2) sitting loaded position (holding a 1 or 2 kg dumbbell in each hand), and (3) sitting loaded shoulder flexion position (holding a 1 or 2 kg dumbbell in each hand). Results: The contraction ratio (CR) and preferential activation ratio (PAR) of the TrA during ADIM had no significant interactional effect between the group and the sitting postures. However, the CR and PRA of the TrA during the ADIM showed significant differences among the three different sitting postures. The CR of the TrA during the ADIM in the sitting loaded shoulder flexion position was significantly increased compared to that in the sitting position (p˂.05). Moreover, the PRA of the TrA muscle during ADIM in sitting loaded and sitting loaded shoulder flexion positions was significantly higher than that in the sitting position (p˂.05). Conclusion: The findings suggest that ADIM in the sitting-loaded shoulder flexion position should be implemented to facilitate TrA activity.

노인인구의 증가와 더불어 뇌졸중 환자들이 증가하고 있다. 치료에도 불구하고 대부분의 뇌졸중 환자들은 장애를 갖게 된다. 이런 장애를 개선하기 위한 뇌졸중 치료의 주요 목적은, 환자들의 기능적 독립을 촉진시키고, 지역사회에 통합하도록 하는 것이다. 지역사회재활 적용시 중요한 점은 장애인과 그들의 가족 그리고 지역사회가 서비스의 우선순위가 무엇인지를 결정하는 것이다. 지역사회 뇌졸중 환자는 물리치료, 작업치료, 언어치료, 보장구, 간호 등 포괄적인 서비스를 필요로 한다. 본 논문의 목적은 우리나라 뇌졸중 환자들에 대한 지역사회재활의 필요성에 대해 논구하는 것이다. Despite intensive therapy, a large proportion of stroke survivors are left with significant disabilities. To improve the disable condition, a major component of stroke management is aimed at facilitating functional independence and community reintegration. There are many evidences that community-based rehabilitation after stroke is most effective when provided by a well-organized multidisciplinary team. Key to the implementation of community-based rehabilitation(CBR) is that the disabled person, their family and their community decide on what the priorities of the service should be. The stroke patients in the community need a wide range of services, including the traditional rehabilitation services of physiotherapy, occupational therapy, speech therapy, social workers, orthotists, nurses and so on. The purpose of this research was to investigate necessity and methods of community-based rehabilitation system in Korea.

Background: Stroke recovery is a long and complex process. Successful stroke recovery seems to be strongly associated with patients’ high motivation and committed participation. Patients’ motivation is a key determinant of successful rehabilitation outcomes, but it is difficult in defining and measuring. Patients’ participation is defined as the degree or extent to which subjects take part in rehabilitation activities and can be measured by observable behavior. Objects: The purpose of this study was to investigate the impact of patients’ level of participation in rehabilitation on functional outcomes in patients with stroke. Methods: Forty post-stroke inpatients participated in this study. The level of rehabilitation participation was measured by the Hopkins Rehabilitation Engagement Rating Scale (HRERS). Other measures used for the evaluation were the Rivermead Mobility Index (RMI) and Korean version of the Modified Barthel Index (K-MBI). Overall measurements were made at early intervention and late intervention. Spearman correlation and multiple regression were used to measure the relationships between HRERS, RMI, and K-MBI. Results: The correlation found between HRERS total scores at early intervention and RMI total scores of late intervention was above moderate (r = 0.607, p < 0.01). RMI total scores at early intervention (p < 0.000), HRERS total scores at early intervention (p < 0.001), and disease duration (p < 0.003) were significant predictors of RMI total scores at late intervention. Conclusion: The level of participation at early intervention was associated with improvement in mobility. The level of mobility at early intervention, disease duration, and patients’ participation at early intervention were important determinants of functional outcome. These findings suggest that patients’ participation should be encouraged in order to achieve successful stroke recovery.

The purpose of this study was to examine the level of knowledge about delirium, experience of assessment tool use, and educational needs about delirium among nurses. This study was a cross sectional descriptive study. Participants were 153 nurses. Data were collected from 3 hospitals using questionnaries. Data were gathered from march 10 to April 10, 2011. The data were analyzed with the SPSS/Win 12.0 program. Data were summariszed using descriptive statistics. The average score for nurses' knowledge about the delirium was 60, of a total score of 100. Only 7 nurses among participants had ever used the delirium tool. More than half of the participant (58.8%) responded that they needed education about intervention and management of delirium. It is important to provide education on delirium to nurses. Continuing educational program focusing on detecting and managing patients with delirium would be helpful for nurses taking care of patiens with delirium.
