최근 코로나19 바이러스로 인하여 언컨텍트 서비스가 본격적으로 활성화됨에 따라 비대면 접촉 원격 의료 서비스를 제공하기 위한 시스템 개발의 필요성이 증가하게 되었다. 본 연구에서는 원격진료를 지원하기 위한 스마트 헬스케어 시스템인 Rm_She(Remote Medical Smart Healthcare System)을 제안한다. Rm_She는 IoT를 기반으로 생체신호를 감지하는 다양한 헬스케어 제품을 하나의 애플리케이션으로 연결하여 여러 가지의 생체신호 정보를 수집 및 관리할 수 있다. 스마트 폰에 실행되는 헬스체크 앱(HC_app)을 이용하여 여러 종류의 생체신호 측정 장치와 무선랜으로 연결하고, 생체신호 값을 HC_app에서 전송 받아, 사용자에게 측정된 생체신호를 출력하고, 해당 정보를 헬스케어관리서버로 전송한다. 헬스케어 서버에서는 측정값을 전송 받아 데이터베이스에 저장하고, 저장된 측정값은 의료진들이 원격에서 실시간으로 모니터링 할 수 있도록 웹서비스로 제공한다.

Sculptured surface machining plays a vital role in the process of bring new Products to the market place. A great variety of products rely on this technology for the production of the dies and moulds used in manufacturing. And, the use or CNC machines and CAD/CAM system has become a vital parts or product development process. But, cusp is inevitable by-product in sculptured surface machining, and it is very difficult to calculate the cusp height correctly. In this study, an analytical cusp height model is proposed considering the radius of the ball end mill, radius of machined workpiece and the inclined angle of convex or concave circular surface. Experiments were performed to check the validity of this proposed model and experimental results showed that the proposed cusp model were very effective.

본 논문에서는 환자나 만성질환자가 공간적으로 구속을 받지 않고 자유롭게 이동이 가능한 상태에서 건강상태 모니터링이 가능한 셀룰러폰(Cellular telephone)에 기반한 통합형 생체신호 계측 및 생체정보 관리가 가능한 생체 관리 시스템을 설계하고자 하였다. 메디컬센서 인터페이스를 센서노드에 부착할 경우 개별적인 센서노드가 필요하기 때문에 생체 디바이스의 문제점을 해결하기 위해서 통합형 메디컬 센서노드 어플리케이션을 설계하였다. 셀룰러폰으로 ECG(Electrocardiogram), 혈압(Blood pressure), 혈당(Blood sugar)과 같은 생체신호를 모니터링해서 비정상적인 생체신호를 판별하며, 당일 측정한 생체신호를 셀룰러폰에 저장해 과거에 측정한 메디컬 기록들과 함께 차트로 리뷰 가능하다. 본 논문에서는 기존의 실시간 생체 모니터링 비해, 개발된 셀룰러폰 기반의 헬스케어용 관리시스템은 고/저혈압, 당료를 갖고 있는 만성질환자가 상시적으로 질병을 관리할 수 있으며, 또한 CDMA의 특성상 넓은 환경에서도 전송이 가능하무로서 무선센서네트워크를 이용하기 위해 CDMA 방식과 통합하였다.

Recently, owing to global warming, average summer temperatures are increasing and the number of hot days is increasing is increasing, which leads to an increase in heat stroke. In particular, outdoor workers directly exposed to the heat are at higher risk of heat stroke; therefore, preventing heat-related illnesses and managing safety have become important. Although various wearable devices have been developed to prevent heat stroke for outdoor workers, applying various sensors to the safety helmets that workers must wear is an excellent alternative. In this study, we developed a smart helmet that measures various vital signs of the wearer such as body temperature, heart rate, and sweat rate; external environmental signals such as temperature and humidity; and movement signals of the wearer such as roll and pitch angles. The smart helmet can acquire the various data by connecting with a smartphone application. Environmental data can check the status of heat wave advisory, and the individual vital signs can monitor the health of workers. In addition, we developed an algorithm that classifies the risk of heat-related illness as normal and abnormal by inputting a set of vital signs of the wearer using a support vector machine technique, which is a machine learning technique that allows for rapid binary classification with high reliability. Furthermore, the classified results suggest that the safety manager can supervise the prevention of heat stroke by receiving feedback from the control system.

An intensive watershed survey including water quality measurement of 6 times was carried out in order to find out the relationship between pollutant load and water quality in a small stream watershed where livestock wastewater is the main source of water pollution. The findings from the survey are as follows. 1) The number of livestock showed large disagreement among county office, myon, and insite survey. It is vital to check the data at the beginning of watershed survey. 2) The fluctuation of streamflow and water quality was so large depending on the day of measurement that it is essential to set up continuous telemetering system to get reliable data about delivery ratio of pollutants. 3) It was helpful for setting the priority of investigation to check water quality and quantity at several points along the stream after dividing the watershed into 5 drainage areas. 4) To control the livestock wastewater, especially in case of cows, it is necessary to have roof system and prevent overland flow from the ground. In case of pig farms, it is recommended to have public treatment system instead of private treatment system. The exact emission load of livestock wastewater was difficult to estimate, and requires more study.

The purpose of this study was to determine the effects of music therapy on changes in the vital signs of patients about to undergo an operation. The patients listened to the music at a time when they were feeling preoperative anxiety up until the preanesthesia was given in the operating room. The subjects for this study were selected from sixty patients to undergo operations, who were hospitalized at Dong Eui hospital in Pusan city. They were assigned to two groups, thirty to the experimental group and thirty to the control group. The subjects were from 20 years old to 69 years old, and had no other problem except the one requiring the operation, and no premedication. The data were collected during the period from July 1 to September 30, 1993. The method used in this study was to measure state-anxiety on the ward in the morning of the operation, and vital signs immediately before leaving for the operating room. Vital signs were measured immediately before the anesthesia was given and after the experimental group had listened to the music during the ten minutes needed to prepare the operation setting. The control group just waited during ten mimutes. Vital signs were check again before the anesthesia was given. The data were analyzed by descriptive statistics, mean±SD, p-value, and t-test using the SPSS progrom. The results of this study are : 1. Systolic blood pressure taken in the operating room was elevated, over the level measured on the ward, by 5.00 ± 15.26㎜Hg in experimental group and 18.67±14.56㎜Hg in control group. (t=-3.5496, p=.0008) 2. Diastolic blood pressure was elevated by 6.67±12.95㎜Hg in experimental group and 18.67±12. 79㎜Hg in control group. (t=-3.6100, p=.0006) 3. Pulse was elevated by 2.931±9.44 / min in experimental group and 8.03±8.37 /min in control group. (t=-2.2144, p=.0307) 4. Respiration was elevated by 0.60±1.35 /min in experimental group and 1.57±1.48 /min in control group. (t=-2.6409, p=.0106) 5. Body temperature was down by 0.13±1.91'c in experimental group and elevated by 1.13±1.11'c in control group. (t=-3.1471, p=.0026) Thus, in this study there was a statistically significant difference in the change in the vital signs between the experimental group treated with music therapy and the control group which received no treatment. Because music therapy is valuable to decrease the anxiety of patients facing operations, the result of this study support its effect in relieving anxiety as a valuable nursing intervention. From this study, the following recommendations can be made : First, it is necessary to further study music therapy to develope a better system and determine optimal time. Second, it is necessary that more detailed re-search on measurement of changes in vital signs be done to determine changes over time intervals.

The number of the PV systems installed in south korea has been gradually increasing. Interest of operation & management of PV System is rising up as PV System installation trends to increase. The vital function of operation & management is the monitoring system. Most monitoring systems are only available for equipment of suppliers and manufacturers. In this study, a monitoring system was implemented to support multi-domain equipment (inverter, junction box, water distribution board, environmental sensors) that are not limited to specific manufacturers. Monitoring system includes a visualization function, which makes it easy for users to check the power generation and the operation status of the equipment of PV System. In the future, this monitoring system will be utilized as an operation & maintenance foundation element in the PV system industry.

IATA(International Air Transport Association, 국제항공운송협회)를 중심으로 항공사 시스템과 연계하여 공항 탑승수속 및 보딩업무를 지원하는 공용시스템 국제 기술표준을 기존의 CUTE(Common Use Terminal Equipment)에서 개선된 CUPPS(Common Use Passenger Processing Systems)로의 전환을 추진 중이다. IATA는 향후 공항 공용시스템의 CUPPS 전환 시 탑승수속 및 보딩업무 관련 각종 장비에 대한 표준 인터페이스 구현 및 항공사 어플리케이션 인증을 통해 항공사의 공용시스템 관련 개발 및 유지보수 비용이 감소될 것으로 예상하고 있다. 인천국제공항은 동북아 주요 공항들과 항공사 유치를 위해 치열하게 경쟁하고 있는 상황에서 항공사의 비용절감 효과를 기대할 수 있는 공항 공용시스템의 CUPPS 전환은 필수적이다. 이에 본 연구에서는 CUPPS 국제 기술표준을 기반으로 사용자의 요구사항에 따라 다양한 기능을 지원할 수 있는 인천국제공항의 컴포넌트(Component) 기반 차세대 공용여객처리시스템의 설계와 구현방안을 제시한다.
