Non-suicidal self-injury (NSSI) has been noted as a significant risk factor for possible suicide attempts. According to the Interpersonal Psychological Theory of Suicide, individuals can attempt suicide after they have acquired the capability to commit it. The acquired capability for suicide can be defined as one's habituated level to the pain and fear associated with suicidal behaviors. This is obtained through constant exposure to painful and provocative events, NSSIs being a prime example. This article reviews prior related studies to determine the extent to which the acquired capability for suicide can be utilized as a predictive factor for fatal suicide attempts following NSSIs. Our review finds a total of 11 studies that directly or indirectly support the claim that the acquired capability for suicide should be considered as a relevant factor linking NSSIs and suicide attempts. Given that NSSIs are most frequently observed in clinical settings, our findings suggest that the acquired capability for suicide will be a useful indicator for clinicians to predict the risk of future suicide attempts by patients.

The DEM (Digital Elevation Model) can be obtained from stereo image pair acquired by LEO satellite. Stereo images may consist of at least two images with different viewing angles to the imaging target for one pass or multiple passes. While each image is generally acquired from each pass in cross-track direction for multiple passes, stereo image pair in along-track direction can be acquired during one pass with attitude control capability for the pitch axis of the satellite. Single pass stereo imaging provides stereo pair image more efficiently on the fact that stereo pair image is generated with less orbit resources and less imaging time consumption. In this paper, the feasibility study result on the stereo pair image collection planning algorithm during single pass is addressed.

The flexible control system for hydraulic pile hammer using main control valve is present to the requirement of rapidly reversing with high frequency. To ensure the working reliability of hydraulic pile hammer, the reversing performance of the main control valve should commutate robustness to various interfere factors. Through simulation model built in Simulink/Stateflow and experiment, the effects of relative parameters to reverse performance of main control are analyzed and the main interfere factors for reversing performance are acquired. Treating reverse required time as design objects, some structure parameters as control factors, control pressure, input flow and gaps between spool and valve body as interfere factors, the robust design of the main control valve is done. The combination of factors with the strongest anti-jamming capability is acquired which ensured the reliability and anti-jamming capability of the main control valve. It also provides guidance on design and application of the main control valve used in large flow control with interferes.

Logistics industry is being an important industry in Vietnam with the contribution from 8-10% of GDP recently. This industry employs about 15 millions people. Increasing the employees' job satisfaction is become one of the most concerns of managers in logistics companies to strengthen the employee engagement and improve their business performance. The aim of this study is to investigate how employees' perceptions of job satisfaction are influenced by factors such as job stress, leadership capability, work-life balance, and demographics. 426 workers in the logistics sector in Vietnam were surveyed online. The acquired data was analyzed using a structural equation model. In total 16 hypotheses were established, 13 of which were deemed to be significant. The results demonstrate how the literature-informed second-order constructs can potentially explain the overall job stress, leadership capability, and work-life balance of employees in the Vietnamese logistics industry. These variables account for 54.8% of job satisfaction. This study makes a theoretical contribution to the extant literature by showing how researching second-order constructs can improve the theory's capacity to predict employees' job satisfaction. The paper concludes with a set of recommendations for the management of logistics firms in Vietnam.

KARI is developing Image Data Acquisition and Control System (IDACS) for pre-processing meteorological and ocean data acquired on geostationary orbit. This paper describes the functions and architecture of IDACS and gives its operation policy including backup operation to overcome limitation of single-configured antenna system. The COMS IDACS provides the capability to receive the raw sensor data and disseminate processed MI data to users via a satellite. From the processed image data, users can produce a set of meteorological and ocean products for a wide range of applications. Most of IDACS subsystems are being developed by Korean technologies and experience acquired from previous projects. In case of COMS geometric correction software module, as it is closely dependent on the characteristics of imagers and spacecraft bus system, it is being co-developed with overseas prime contractor who develops spacecraft bus system.

The valve performance has been evaluated from the theoretical equation based on design information such as packing thrust, spring preload and friction coefficient(${\mu}$). The accuracy of those data can be lower than that of vendor's initial design data. Especially, the friction coefficient can be degraded with time than the original condition and the valve performance calculated using the previous friction coefficient can not be available. Accordingly, this paper is describing a new performance evaluation method of valve based on diagnostic test data which are acquired from a site valve tested in static and dynamic conditions. Especially, this paper provides a new method using friction coefficient(${\mu}$) which is derived from the diagnostic test data acquired in the valve's design basis condition.

Due to harsh conditions of disaster areas, understanding of current feature of collapsed buildings, terrain, and other infrastructures is critical issue for disaster managers. However, because of difficulties in acquiring the geographical information of the disaster site such as large disaster site and limited capability of rescue workers, comprehensive site investigation of current location of survivors buried under the remains of the building is not an easy task for disaster managers. To overcome these circumstances of disaster site, this study makes use of an unmanned aerial vehicle, commonly known as a drone to effectively acquire current image data from the large disaster areas. The framework of 3D model reconstruction of disaster site using aerial imagery acquired by drones was also presented. The proposed methodology is expected to assist rescue workers and disaster managers in achieving a rapid and accurate identification of survivors under the collapsed building.

Jointness is a core concept of ROK military reform plan. ROK military has pursued to transform its military organization and capability for enhancing jointness and joint operation after the 1990s. It has strengthened the organization of JCS(Joint Chief of Staffs), introduced joint education, and acquired modernized weapons and equipment proper for joint operation. The 1986 Glodwater-Nichols Act of the U.S. military and lessons of the recent war provided a good direction how ROK military should take measures to enhance jointenss. In fact, defense reform efforts for jointness has produced invaluable fruits for transforming industrial age military forces into information age one which possesses more strong combat capabilities and develops joint business for efficient defense management. Nevertheless, there are many issues ROK military should address for stepping up the jointness. This paper well analyzes practical problems and issues ROK military faces to develop jointenss and draws policy recommendations for the policy makers.
