조직공정성과 조직후원인식이 사회복지사의 조직몰입에 미치는 영향에 관한 연구
최소연 한국사회복지행정학회 2005 한국사회복지행정학 Vol.7 No.3
본 연구는 사회복지조직의 성과에 있어 구성원의 긍정적인 태도인 조직몰입이 중요하다는 인식하에 조직공정성(절차․상호작용․분배)과 조직후원인식이 사회복지사의 조직몰입에 미치는 영향을 파악하고자 하였다. 이를 위해 사회복지사 388명을 대상으로 조직공정성과 조직후원인식이 조직몰입에 미치는 직접영향과 조직공정성이 조직후원인식을 통해 조직몰입에 미치는 간접영향을 구조방정모형을 통해 검증하였다. 연구결과 조직공정성이 조직후원인식에, 조직후원인식이 조직몰입에 직접적인 영향을 미치는 것으로 나타났다. 그러나 조직공정성 중 절차와 분배공정성은 조직몰입에 직접영향을 미치지 않았고 조직후원인식의 매개효과를 통해 간접영향을 미치는 것으로 확인되었다. 연구결과 조직성원이 조직에서 긍정적인 태도를 형성하는 과정에 대한 이해의 중요성을 제시하였으며, 사회복지사의 조직에 대한 몰입에 선행하여 조직이 구성원에 대해 몰입해야 할 필요성을 강조하였다.

Trigeminal Autonomic Cephalalgia (TAC) encompasses cluster headache, paroxysmal hemicrania, short-lasting unilateral neuralgiform headache attacks (SUNHA), and hemicrania continua. The treatment of cluster headache consists of acute therapy and preventive treatment. The available options for acute treatment in South Korea include high-flow O2 inhalation, zolmitriptan oral medication, and intranasal lidocaine spray. In the transitional phase of cluster headache, oral steroids and suboccipital steroid injections are commonly used. Verapamil and lithium have been widely used as preventive medications, but recently, galcanezumab, a monoclonal antibody targeting calcitonin gene-related peptide, has emerged as a recognized preventive treatment for cluster headache. In addition, neuromodulation techniques, such as noninvasive vagus nerve stimulation, sphenopalatine ganglion stimulation, occipital nerve stimulation, and deep brain stimulation, are also available for the treatment of cluster headache. Paroxysmal hemicrania and hemicrania continua are absolutely responsive to indomethacin; however, when indo methacin is contraindicated, alternative treatments are necessary. Reported alternatives include topiramate, vagus nerve stimulation, verapamil, and carbamazepine for paroxysmal hemicrania, and topiramate, gabapentin, and neurostimulation for hemicrania continua. Treatment options for SUNHA are limited, but short-term preventive approaches such as intravenous lidocaine, as well as the use of lamotrigine for preventive treatment, can be considered.
Reverse Engineering for Xilinx FPGA Chips using ISE Design Tools

SRAM-based Field Programmable Gate Arrays (FPGAs) are more widely used compared to Flash-based and anti-fuse based FPGAs in various industries. One disadvantage of the SRAM-based FPGA is that SRAM is natively volatile and thus it requires additional nonvolatile memory to store the netlist information of the circuit outside the FPGA. When the FPGA is powered on, the bitstream file is transferred from the external nonvolatile memory to the SRAM-based FPGA. The secure issues arise if the bitstream is modified or corrupted by attacker resulting in a fatal problem in the circuit. Therefore, reverse engineering that converting a bitstream into an internal netlist is necessary to find such harmful modification. In this paper, we describe the overall process of reverse engineering based on ISE design tools in details. According to the experimental results, the proposed reverse engineering tool can recover 88% internal circuit as for the example of 64-bit LFSR design.
