  • Because each building is built in different time, there exists different equipment to meet the need for each age. Before the announcement of "Community Management Regulation", the old communities usually suffer the problem of lower requirement and living quality. This may bring some security problem that we should face. In this research, we construct "Building Administration System" to provide users a tool to perform a standard operation procedure in community management. This powerful tool will also help manager to effectively handle important tasks in property administrating by reducing unnecessary documentation. In the current regulation, all community committee members shall be voted each year. This will seriously affect the cumulative of management knowledge and cause a worse efficiency. In this research, we use Object Oriented concept and Visual Modeling techniques to combine with Interbase, ER/Studio, and Delphi to develop this management system for Building Property. Through the help of current computing technology, we can solve the problem that can not be inherited and the storing of the huge amount of data. In this system, we develop the modules such as Basic Data Module, Administrative Expense Calculation, Receipt Print, and Inquiring for Inheritance. In this system, we have integrated all houses, parking lots, and public equipments in it. Manager will only need to handle some basic accounting data; the system will automatically handle the rest. Through the help of this system, the community management staff can be easily accomplished and put more manpower on some needed aspect to improve the living quality.

  • Objectives: Dental or maxillofacial emergencies are uncommon during pregnancy, but if they occur, they are challenging to treat due to potential risks. The mother should not be denied necessary medical or dental care because of pregnancy. The aim of the study is to observe outcomes of pregnancy in patients requiring emergency minor oral surgical procedures during gestation and to determine the safety of the pregnant woman undergoing the procedure and the fetus. Materials and Methods: The study was conducted on 52 pregnant women requiring emergency oral surgical procedures. A standard treatment protocol for treatment of specific entities was followed. Close monitoring and observation were the primary goal of treatment. All patients were followed postoperatively until complete recovery from the surgical procedures and then until birth of the baby. A control group of 52 healthy pregnant patients who did not require oral surgical procedures was considered for statistical analysis. The measurements to calculate observation were fetal loss (spontaneous abortion), preterm birth, low-birth weight, or incidence of any congenital anomalies in the baby and its association with surgical procedures. Results: No fetal loss occurred in any of the cases. However, four patients experienced preterm birth and seven neonates exhibited low birth weights. No congenital abnormalities were discovered. In one instance, a patient who underwent surgery for a mandibular symphysis fracture under general anesthesia in the 31st week of pregnancy experienced labor pain on the fourth postoperative day, requiring an emergency Caesarean section. Conclusion: The results of our study demonstrate that, compared to the control group, minor emergency surgeries performed during pregnancy have no discernible negative effects on the fetus. These procedures can safely be performed by adhering to our described protocols.

  • WiMAX 환경에서 사용되는 암호학적 키는 베이스 스테이션의 통신 범위안에 위치하는 이동 노드(노트북, PDA, 휴대폰 등)들에 의해 일정기간동안 사용되어지며, 이 때 이동 노드에 의해 사용되어지는 키는 이동 노드가 베이스 스테이션의 통신 범위를 벗어날 때까지 사용된다. 그러나 이동 노드가 베이스 스테이션의 통신 범위를 벗어나거나 이동 노드가 베이스 스테이션과 통신하기 위해 통신 범위 안에 진입하려고 할 때 이동 노드와 베이스 스테이션 사이의 통신구간은 무선으로 동작되기 때문에 man-in-the-middle 공격과 같은 내부 공격에 매우 취약한 문제점을 가지고 있다. 이 논문에서는 이동 노드가 베이스 스테이션과 통신하려고 할 때 베이스 스테이션에서 발생되는 암호학적 보안 공격위험과 통신 오버 헤드를 줄이기 위해서 이동 노드들이 사용하는 키를 재 사용할 수 있는 분산키 설립 프로토콜을 제안한다. 제안된 분산키 설립 프로토콜은 통신과정 중에 발생되는 키의 재사용을 통해 베이스스테이션과 이동 노드 사이에서 발생되는 오버 헤드를 줄일 수 있을 뿐만 아니라 상호 인증에 필요한 공유키를 노드자신이 생성한 난수 값을 통해 생성하여 IEEE 802.16 표준보다 안전성을 향상시키고 있다.

  • Wildfire disasters in the United States impact lives and livelihoods by destroying private homes, businesses, community facilities, and infrastructure. Disaster victims suffer from damaged houses, inadequate shelters, inoperable civil infrastructure, and homelessness coupled with long-term recovery and reconstruction processes. Cities and their neighboring communities require an enormous commitment for a full recovery for as long as disaster recovery processes last. State, county, and municipal governments inherently have the responsibility to establish and provide governance and public services for the benefit and well being of community members. Municipal governments' comprehensive and emergency response plans are the artifacts of planning efforts that guide accomplishing those duties. Typically these plans include preparation and response to natural disasters, including wildfires. The standard wildfire planning includes and outlines (1) a wildfire hazard assessment, (2) response approaches to prevent human injury and minimize damage to physical property, and (3) near- and long-term recovery and reconstruction efforts. There is often a high level of detail in the assessment section, but the level of detail and specificity significantly lessons to general approaches in the long-term recovery subsection. This paper aims to document the extent of wildfire preparedness at the county level in general, focusing on the long-term recovery subsections of municipal plans. Based on the identified challenges, the researchers provide recommendations for better longer-term recovery and reconstruction opportunities: 1) building permit requirements, 2) exploration of the use of modular construction, 3) address through relief from legislative requirements, and 4) early, simple, funding, and the aid application process.

  • Background: This study aims to develop an evaluator that can quickly and accurately evaluate the shielding of low-energy industrial radiation generators. Methods: We used PyQt to develop a graphical user interface (GUI)-based program and employed the calculation methodology reported in the National Council on Radiation Protection and Measurements (NCRP)-49 for shielding calculations. We gathered the necessary factors for shielding evaluation using two libraries designed for Python, pandas and NumPy, and processed them into a database. We verified the effectiveness of the proposed program by comparing the results with those from safety reports of six domestic facilities. Results: After verifying the effectiveness of the program using the NCRP-49 example, we obtained an average error rate of 1.73%. When comparing the facility safety report and results obtained using the program, we found that the error rate was between 1.09% and 6.51%. However, facilities that did not use a defined shielding methodology were underestimated by 31.82% compared with the program (the final barrier thickness satisfied the shielding standard). Conclusion: The developed program provides a fast and accurate shielding evaluation that can assist personnel that work in radiation generator facilities and government officials in reviewing safety.

  • The research comprehensively studies the axial compression performance of T-shaped concrete-filled thin-walled steel tubular (CTST) long columns after fire exposure. Initially, a series of tests investigate the effects of heating time, load eccentricity, and stiffeners on the column's performance. Furthermore, Finite Element (FE) analysis is employed to establish temperature and mechanical field models for the T-shaped CTST long column with stiffeners after fire exposure, using carefully determined key parameters such as thermal parameters, constitutive relations, and contact models. In addition, a parametric analysis based on the numerical models is conducted to explore the effects of heating time, section diameter, material strength, and steel ratio on the axial compressive bearing capacity, bending bearing capacity under normal temperature, as well as residual bearing capacity after fire exposure. The results reveal that the maximum lateral deformation occurs near the middle of the span, with bending increasing as heating time and eccentricity rise. Despite a decrease in axial compressive load and bending capacity after fire exposure, the columns still exhibit desirable bearing capacity and deformability. Moreover, the obtained FE results align closely with experimental findings, validating the reliability of the developed numerical models. Additionally, this study proposes a simplified design method to calculate these mechanical property parameters, satisfying the ISO-834 standard. The relative errors between the proposed simplified formulas and FE models remain within 10%, indicating their capability to provide a theoretical reference for practical engineering applications.
