Experience of Mental Health Professionals Collaborating with Peer Supporters in a Community Mental Health Service Team

This study explored how mental health professionals collaborate with peer supporters with mental disabilities in a community mental health institution.From January 19 to February 23,2021,three 60 min interviews were conducted with six mental health professionals working at a Korean community center.The results were qualitatively analyzed and divided into four themes and eight categories.The four themes were the perceptions of and challenges in working with peer supporters with mental disabilities,conflict and confusion about working with peer supporters,forming partnerships with peer supporters,and policy support for peer supporters’job security.Participants reported vague anxiety about working with a peer supporter and difficulties with the trial-and-error process of adjusting to the role as challenging.Over time,however,they realized that they needed to make an effort to develop meaningful relationships with peer supporters and mental health professionals.Thus,through this study,we realized that there was a need to improve the system,such as building infrastructure for job stability for peer support workers and capacity building tailored to the mental disorders.Although peer supporters play various roles while working with mental health professionals,this study showed the possibility of mutual growth through communication and cooperation.These findings will help prepare systems necessary for collaboration between the two teams amidst the increasing institutionalization of peer support for mental disorders.

XML-based Data Processing in Network Supported Collaborative Design

In the course of network supported collaborative design, the data processing plays a very vital role. Much effort has been spent in this area, and many kinds of approaches have been proposed. Based on the correlative materials, this paper presents extensible markup language （XML） based strategy for several important problems of data processing in network supported collaborative design, such as the representation of standard for the exchange of product model data （STEP） with XML in the product information expression and the management of XML documents using relational database. The paper gives a detailed exposition on how to clarify the mapping between XML structure and the relationship database structure and how XML-QL queries can be translated into structured query language （SQL） queries. Finally, the structure of data processing system based on XML is presented.

Mechanism and technology study of collaborative support with long and short bolts in large-deformation roadways

Common short bolts of equal length are widely used to support the roofs of roadways in coal mines.However, they are insufficient to keep the roof stable against large deformations, so docking long bolts with high levels of elongation that can adapt to large deformations of the surrounding rock have been adopted. This paper proposes a collaborative support method that uses long and short bolts. In this study,the mechanism of docking long bolts and collaborative support was studied. Numerical simulation, similarity simulation, and field testing were used to analyze the distribution law of the displacement, stress,and plastic failure in the surrounding rock under different support schemes. Compared with the equal-length short bolt support, the collaborative support changed the maximum principal stress of the shallow roof from tensile stress to compressive stress, and the minimum principal stress of the roof significantly increased. The stress concentration degree of the anchorage zone clearly increased. The deformation of the roof and the two sides was greatly reduced, and the subsidence shape of the shallow roof changed from serrated to a smooth curve. The roof integrity was enhanced, and the roof moved down as a whole. Plastic failure significantly decreased, and the plastic zone of the roof was within the anchorage range. The similarity simulation results showed that, under the maximum mining stress,the roof collapsed with the equal-length short bolt support but remained stable with the collaborative support. The collaborative support method was successfully applied in the field and clearly improved the stability of the surrounding rock for a large deformation roadway.

Corroborative Activities and Recognition Between Community Comprehensive Care Unit’s Nurses and Care Managers in Supporting Discharge of Elderly from Hospital - A Secondary Publication

Objective: The purpose of this study was to clarify the collaborative activities and mutual recognition between community comprehensive care unit nurses (Ns) and care managers (CM) in supporting the discharge of the elderly from the hospital. Methods: A total of 300 nurses working in community comprehensive care wards and 360 care managers working in B City in A Prefecture were surveyed using an anonymous self-administered questionnaire. Results: The highest percentage of responses regarding necessary collaborative activities with multiple professions in supporting hospital discharge were the same for Ns and CMs. The items regarding practice with the highest percentages were “relationship as a team” for Ns, and “user-centered awareness” for CM. While these professionals were willing to share information about their patients’ lives after discharge, the percentage of those explaining their expertise was low. It is thought that collaborative activities focusing on these aspects would lead to more appropriate discharge support.

SVM-DT-Based Adaptive and Collaborative Intrusion Detection

As a primary defense technique, intrusion detection becomes more and more significant since the security of the networks is one of the most critical issues in the world. We present an adaptive collaboration intrusion detection method to improve the safety of a network. A self-adaptive and collaborative intrusion detection model is built by applying the Environmentsclasses, agents, roles, groups, and objects(E-CARGO) model. The objects, roles, agents, and groups are designed by using decision trees(DTs) and support vector machines(SVMs), and adaptive scheduling mechanisms are set up. The KDD CUP 1999 data set is used to verify the effectiveness of the method. The experimental results demonstrate the feasibility and efficiency of the proposed collaborative and adaptive intrusion detection method. Also, the proposed method is shown to be more predominant than the methods that use a set of single type support vector machine(SVM) in terms of detection precision rate and recall rate.

A NEW APPROACH TO THE DESIGN OF A SYSTEM FOR FEATURE EXTRACTION BASED ON HUMAN-COMPUTER COLLABORATIVE TACTIC

We are involved in an embarrassing situation that the limited capa-bility of automated feature extraction in digital photogrammetric systems cannotsatisfy the increasing needs for rapid acquisition of semantic information for appli-cations.Facing this challenge,a new tactic,Human-Computer Collaborative（HCC）tactic,and a corresponding new method,Operator-Object Directed（OOD）method,are proposed for the design of a system for feature extractionfrom large scale aerial images.We hold that in almost all technical complex sys-tems,full automation will be neither technically feasible nor socially acceptable.The system should be designed to optimize through the cooperative operation withtwo agents in the system:the human and the computer.

家庭教育指导需求与社区支持现状——基于对上海1000名家长的调查

如何提高社区的家庭教育支持能力,是上海构建完善学校、家庭、社会协同育人体系的关键。基于对1000名育有未成年子女的上海家长的问卷调查发现,家长普遍面临家庭教育问题,对家庭教育指导的需求度较高;家长对家庭教育指导的需求呈现个性化、多元化特征;家庭特征的复杂性、特殊性极大地增加了家庭教育的指导难度。目前上海的社区在支持家庭教育方面的设施和场所多元化,服务内容丰富,平台作用彰显,不足之处主要在于家庭教育支持设施和场所的知晓度不高、指导服务的有效性不足以及缺乏对家长的心理支持等方面。未来,上海可通过加强线上线下宣传、探索服务模式、搭建互助平台等措施来进一步推动社区支持家庭教育工作的开展。

府际财政应急援助的嵌入式协同治理机制构建

对口支援作为中国特色的府际财政应急援助机制,是突发事件下府际财政协同治理的重要实践形式。然而,“动员式协同”的府际财政应急援助实践在权责划分以及利益激励等方面还存在一些问题,亟需纳入法治化轨道。嵌入理论为府际财政应急援助提供了更优的模式选择,“嵌入式协同”的府际财政应急援助治理模式在组织形态、制度基础和动力因素方面有其优势,有利于实现纵向上政府由“主导”到“引导”的转型,横向上政府由“被动”到“主动”的转变,构建应急财政权力的新型配置格局。应当基于“结构嵌入(纵向引导与横向协作的有机结合)—规则嵌入(法律体系与互助协议的联合规制)—动力嵌入(权责划分与利益补偿的有效衔接)”的框架构建其相应机制。

煤层群采动下围岩应力演化规律及协同控制技术研究

针对煤层群开采过程中巷道支护困难问题,以贵州土城矿212回风石门为工程背景。综合采用现场调研、数值模拟、相似模拟及现场试验等手段,揭示了212回风石门应力演化规律,并提出了“卸−转−固”协同控制技术。研究结果表明:212回风石门遭受破坏的主要原因是煤层群采动过程中存在的地质力学问题导致了围岩失稳。巷道底板及两帮在采动过程中产生不同程度的应力集中。当遭受垂直应力挤压时,巷道底部承受的挤压力较大,而顶部围岩承受的拉伸力较大,由于力学不平衡导致围岩的破坏。基于此提出了“卸−转−固”协同控制技术。通过爆破卸压的方式,利用爆破产生的冲击波引起围岩的震动和应力波动,使表层围岩中原本集中的应力分散到更深的围岩区域,降低表层围岩的应力集中程度。同时,利用爆轰和封孔工艺进一步加固卸压孔周围的围岩,形成两个承载结构。即由巷道支护体形成的内承载体和由深部围岩形成的外承载体。两者相互作用有效承受巷道浅部及深部围岩的应力,并转移到支护结构,起到保护和稳定围岩的作用。利用该技术在212回风石门现场试验,结果显示:使用该技术区域应力长期趋于稳定甚至缓慢降低,巷道顶底板及两帮移近速率分别降低了74.49%及47.67%,底鼓量降低了77.2%。而未使用该技术区域应力出现不同程度的上升,表面位移收敛严重。由此可得,围岩控制效果显著。该技术已成功推广到贵州其他不同地质环境的煤矿,均取得了显著效果。

基于数据模型协作的海上钻井溢流早期预测预警

为防止海上钻井过程中井喷事故的发生,提出基于数据模型协作的海上钻井溢流早期预测预警方法。首先,建立基于粒子群优化(PSO)-最小二乘支持向量机(LSSVM)(PSO-LSSVM)的溢流风险预测模型,预测钻井监测参数未来时长内的趋势,并分析溢流事件与表征参数之间的关联关系;然后,建立基于朴素贝叶斯方法的钻井单参数溢流概率估算模型,并通过优化的D-S方法融合多个钻井参数的概率,分级预警溢流事件。结果表明:基于PSO-LSSVM的预测模型所得的溢流表征参数,预测误差较低;因对溢流事件的敏感度不同,单钻井参数所表征的溢流事件概率存在一定偏差;融合后的预警模型能够解决单参数的预警时间不一致的问题,排除误报警的可能。

倾斜厚煤层动压巷道变形破坏规律及高预紧力锚杆锚索协同支护技术研究

针对庞庞塔煤矿倾斜煤层巷道局部收敛变形过大的问题,以5-1062巷为工程背景,通过理论分析和数值模拟,分析总结了巷道失稳机理和变形破坏的主要原因,探讨了围岩变形对动压的响应机制,揭示了高预紧力锚杆锚索协同支护技术对围岩变形的控制机理,并针对原有支护方式不足提出以高预紧力锚杆锚索协同支护技术为核心的优化方案,结合现场条件进行了工业性试验。研究结果表明:护表面积小、预应力低、锚杆(索)支护不协同是5-1062巷支护效果不佳的主要原因;对于倾斜煤层巷道,垂直动压对两帮的影响大,水平动压对顶板的影响大,与水平动压相比,垂直动压是影响巷道收敛变形的主导因素;高预紧力锚杆锚索协同支护技术能给巷道浅部围岩施加均匀的高预应力,保证围岩处于较为稳定三向应力状态,有效提升围岩的稳定性。现场监测表明,采用支护优化方案后,巷道变形得到有效控制,无锚杆锚索破断现象,局部网兜现象得到抑制,现场支护效果良好,为类似工程地质条件下的煤矿巷道围岩变形控制提供参考。
