Objectives : The purpose of this study is to report the effect of Korean medicine on the pancreatic carcinoma patient. Method : A patient was diagnosed as unresectable pancreatic carcinoma. She complained insomnia, abdominal pain, dyspepsia and sleep disturbance. She was treated by Korean medicine composed of acupuncture, herbal medication and wild ginseng pharmacopuncture. Results : All symptoms took a favorable turn after Korean medicine treatment. As treatment was performed, as intensity of pain, insomnia, dyspepsia and fatigue were decreased. Conclusion : This study suggests that Korean medicine treatment has effectiveness for improvement of cancer related symptoms of a pancreatic carcinoma patient. Consequently, the treatment is helpful in improving quality of life.

The advancement of autonomous driving technology plays a pivotal role in transforming the driving environment and enhancing the efficiency and convenience of vehicle operation. However, autonomous driving systems are composed of various Electronic Control Units (ECUs) connected through networks, making them susceptible to security attacks such as hacking. These attacks can lead to severe consequences, including system manipulation and personal data breaches, highlighting the critical issue of security. As a result, evaluating the security of autonomous driving systems is of utmost importance. Security evaluation involves thorough validation of various attack scenarios and threat models for ECUs to identify potential vulnerabilities and weaknesses. To achieve this, our research leverages Hardware-in-the-Loop (HIL) simulation and the Controller Area Network (CAN) Fuzzer technique. HIL simulation is a robust method that combines real hardware and software components to conduct experiments under conditions closely resembling actual operating environments. In this study, we establish an HIL simulation environment to simulate the interaction between an autonomous driving logic-equipped vehicle model and ECUs. The CAN Fuzzer is a tool that transmits massive input data to ECUs via the CAN communication protocol, generated randomly. Such input data is employed for modeling unexpected and attack scenarios. Fuzzer, in conjunction with the connected CAN bus network, evaluates how ECUs respond to attacks. The primary objective of this study is to develop a methodology for assessing the security of autonomous driving ECUs by combining HIL simulation and the CAN Fuzzer technique. This methodology encompasses the detection of potential security vulnerabilities and the assessment of exploitability, among various factors, including emergency response calculation. Therefore, in this paper, we conduct research involving HIL simulation to test the systems response in various situations of autonomous vehicles and employ CAN Fuzzer to identify ECU vulnerabilities in the development of a security evaluation methodology

Objectives : The purpose of this study is to report the effect of Korean Medicine Treatment (KMT) on the advanced gastric carcinoma (AGC) patient. Method : One advanced gastric carcinoma patient was treated by Korean Medicine Treatment composed of pharmacopuncture, acupuncture and herbal medicine. At the same time, he received chemotherapy (S-1 and Cisplatin) and radiotherapy. The effect of KMT was measured by scanning with Computed tomography (CT) and Esophagogastroduodenoscopy (EGD). Response was evaluated using the Response Evaluation Criteria in Solid Tumors (RECIST) Committee classification. Result : The tumor was disappeared after the treatment during 13 months (Complete Response (CR)). As treatment was performed, chemoradiation therapy induced complication was alleviated. Conclusion : This case provides us a possibility that Korean Medicine Treatment offers potential benefits for advanced gastric carcinoma patient.

Glass, silicon, and ceramic substrates have been mainly used in lab-on-a-chip fields and micro fluidics. Recently, plastic substrates have been employed increasingly because fabrication costs are inexpensive, manufacturing process is simple, and mass production is possible. In particular, PMMA, PC, and COC substrates which are similar to optical properties of the glass substrates have been implemented. Main issues of using plastic substrates are to bond two substrates without damage of the microchannel. In this paper, microchips have been fabricated with solvent bonding among the various bonding methods which are proper to mass production. And we present solvent bonding method does not penetrate into the microchannel.

In this paper, Ni-Co alloys were characterized by various DC, Pulse(width, frequency) plating condition. Vickers Hardness testing machine, Optical microscope and X-ray diffraction(XRD) were used to characterize the alloy coatings respectively. Electrolyte flows were simulated to improve the deposition uniformity and mechanical properties. Good uniformity of electrolyte flow was found out at 22.5° of inlet angle.

This paper introduces a study on the development of a fuel cell system model and the creation of a vehicle model using dSPACEs Automotive Simulation Model. The research involves selecting specific road segments and utilizing OpenStreetMap(OSM) data to develop an accurate simulation of real road conditions. We performed simulations by integrating vehicle model, road model, and scenario model, and confirmed the vehicles performance and condition in various driving situations. Additionally, this research monitors the state of charge(SOC) of the battery and changes in the fuel cell system output during vehicle operation. This paper provides essential information on the development of fuel cell-based vehicle model and realistic road model, aiding in the understanding of vehicle performance under various operational conditions.
