U-Health에 대한 연구는 환자, 의료장비에 대한 위치 추적을 통한 의료업무 지원관리 분야로 집중되고 있다. 본 논문에서는 RFID Tag를 의료 측정에 적용한다. 즉, RFID Tag를 이용하여 방사선치료에서 사용되는 결손조직 보상체의 체표 윤곽을 모델링하는 방법을 제안한다. 기존의 모델링 방법은 환자의 체표 윤곽을 컴퓨터단층촬영이나 자기공명촬영을 사용한 의료영상을 이용해왔다. 이러한 방법은 고가의 비용이 소요되고 방사선치료에 따른 체표윤곽의 변화에 대응하지 못한다. 본 연구에서는 U-Health에서 기본적으로 사용하는 RFID Tag를 환자의 체표윤각에 고정하여 3차원 위치정보를 획득한다. 체표윤곽에 위치한 RFID의 상대적 위치를 통해 결손조직 보상체를 제작하고 이의 유용성 평가를 위해 기하학적, 선량학적 평가를 수행하였다.

착의행동을 일으키는 전단계의 감각으로서 국소의 냉감각과 체표 각 부위에 있어서의 냉점분포에 대하여 측정을 하였다. 피험자는, 냉점분포 측정에 한국인 여자 대학생 30명, 냉감각측정에는 한국인과 일본인 여자 대학생 8명을 대상으로 하였으며, 환경조건은 실온 $29^{\circ}C{\pm}1^{\circ}C$, 상대습도 $55{\pm}5\%$의 인공기후실로 하였다. 냉자격으로서는 $0^{\circ}C$의 냉각이 사용되었으며, 측정부위는 냉점분포 측정의 경우 체표 20부위, 냉감각 측정의 경우 체표 13부위로 하였고 측정결과는 다음과 같다. (1) 체표면의 냉점분포 밀도는 부위에 따라서 다르며, 체간부와 두부는 냉점분포 밀도가 높고 말단부에 갈수록 그 분포가 낮아졌다. 특히 가장 민감한 부위는 복부였다. 즉 체간부와 두부는 중핵온을 일정하게 보지하므로서 중핵부 체내온의 변화를 방어하기 위한 온도 수용 부위로서의 역할을 하고 있으며, 말초부는 냉점분포가 낮아서 기온에 따라 체표온(외각온)을 광범위하게 변화시키는 사지부의 온도정보입력의 역할을 담당하고 있다고 하겠다. (2) 각 부위에 있어서의 냉감각 순위는 일본인과 한국인 피험자간에 고도의 상관(r=0.93)이 보여져, 양 피험자군간에 차이는 볼 수 없었다. 3) 냉점분포 밀도가 높은 부위인 복부는 냉감각도 가장 민감하였으며, 냉점분포 밀도가 낮은 하퇴부는 냉감각 감수성도 낮게 나타났다. (4) 발바닥과 손바닥은 냉감각을 민감하게 느끼는 부위임에도 불구하고 냉점분포 밀도가 낮게 나타났으며, 이는 특수성이 있는 부위로서 주목되어지는 결과라고 하겠다.

In Vivo dosimetry is a method to evaluate the radiotherapy; it is used to find the dosimetric and mechanical errors of radiotherapy unit. In this study, on-line In Vivo dosimetry was enabled by measuring the skin dose with MOSFET detectors attached to patient's skin during treatment. MOSFET dosimeters were found to be reproducible and independent on beam directions. MOSFET detectors were positioned on patient's skin underneath of the dose build-up material which was used to minimize dosimetric error. Delivered dose calculated by the plan verification function embedded in the radiotherapy treatment planning system (RTPs), was compared with measured data point by point. The dependency of MOSFET detector used in this study for energy and dose rate agrees with the specification provided by manufacturer within 2% error. Comparing the measured and the calculated point doses of each patient, discrepancy was within 5%. It was enabled to verify the IMRT by using MOSFET detector. However, skin dosimetry using conventional ion chamber and diode detector is limited to the simple radiotherapy.

The development of ubiquitous healthcare technology and portable electronic devices requires new energy sources for providing continuous power supply. This study particularly focuses on an energy harvesting system capable of charging energy using clothing. One of the sources for energy harvesting is heat energy, which is the difference in temperature of the body and the surrounding environment. In this study, the skin temperature distribution of the human body was empirically measured to determine the basic materials needed to develop heat energy harvesting clothing. The distribution of skin temperature in different sections of the human body was analyzed. The analysis found that the skin temperature of the upper body was higher than that of the lower body. The area close to the heart with a lot of blood flow was especially high. The skin temperature of the back side of the body, such as the back of the neck, upper back, and waist, was higher than that of the front side of the body. As for the arms, the skin temperature of the upper arms was higher than that of the lower arms, and the skin temperature of the back side of the arms was lower than that of the front and the flank side of the arms. The difference in the average skin temperature and the environment temperature was highest at the back of the neck, and thereby is considered to be the most appropriate section to integrate the heat energy harvesting function and structure. The following sections had the next highest difference in values, listed in descending order: the back of the waist, the sides of shoulders, the front chest area, the front side of the upper arms, and the front abdomen. Based on the skin temperatures of the different sections of the human body, this study outlines the basic guidelines for developing heat energy harvesting clothing.

1999년 여름철 우리 나라의 몇몇 해수 어류 양식장과 종묘 배양장에서 Vibrio harveyi가 원인균으로 생각되는 질병이 발생하였다. 어종별 특징적인 증상으로는 넙치의 탈장, 복부팽만, 장충혈, 장액 삼출 및 간출혈과 조피볼락의 체표 궤양 및 간울혈을 들 수 있었으며 같은 시기에 감염증을 나타낸 turbot에서는 체표 출혈과 장출혈이 특징적인 증상이었다. 이 중에서도 특히 넙치의 병징은 에드와드병으로 추정되기 쉬운 특징이 있기 때문인지 각 양어장에서는 간단히 에드와드병으로 진단하고 그에 대한 치료가 실시되고 있었으나 치료 효과가 비교적 낮아서 피해가 증가되고 있는 실정이었다.

In this paper, the discharge phenomena and electromagnetic waves caused by discharge with insertion of a solid insulator and flame between sphere-sphere electrodes in air ware investigated. The surface discharge light and patterns of flame generated on a solid insulator surface were observed by using a CCD(Charged Coupled Device) camera. Also, the radiated electromagnetic waves were measured by using a biconical antenna and a spectrum analyzer. The surface discharge light generated on the solid insulator surface was larger and the size of flame was smaller by increasing allied voltages. Also, voltage distortion by voltage drop was strongly revealed when a insulator surface was polluted. When a solid insulator surface was not polluted, the electric field stength of electromagnetic waves was 10∼17[dBuV/m] higher than a polluted solide insulator, and 5∼9[dBuV/m] higher than a polluted solide insulator and flame.

This study was conducted to investigate the effects of mixing with unfamiliar piglets on changes in the body surface temperature of sows and piglets during the suckling period. A total of 123 pigs (12 sows and 111 piglets) were used for this study. A control group of piglets of the same litter was maintained in the farrowing pen and compared to a treatment group of piglets of three different litters mixed by removing the partition in the farrowing pen. In the treatment group, mixing of piglets was performed at 10:00 a.m. on day 11 after parturition, and the body surface temperature of sows and piglets was taken using a thermo-graphic camera at 30 minutes after mixing. In the case of sows, the average surface temperature of the treatment group ($37.1^{\circ}C$) was significantly higher than that of the control ($36.3^{\circ}C$; p<0.05); however, the hot spot temperatures did not differ significantly between groups. In contrast, the average surface temperature of piglets was significantly decreased by mixing (37.5 and $36.0^{\circ}C$ in the control and treatment, respectively; p<0.01). Moreover, the hot spot temperature tended to be lower in the treatment ($39.1^{\circ}C$) than the control ($39.4^{\circ}C$), although there was no significant difference (p=0.079). These results suggest that mixing of unfamiliar piglets during the suckling period leads to changes in the body surface temperature of sows and piglets. In the future, the correlation between body surface temperature and body core temperature should be analyzed, and additional studies investigating the effects of mixing on the physiological changes in sows and piglets are required.

The aim of this study is to evaluate the effect of skin dose and PDD by using wounds protecting gauzes or Vaselinespread gauzes. And it was studied that the possibility to substitute custom bolus into gauzes. 4MV photon (CL600C, varian, US), Polystyrene Phantom (30(W) X30(L) X 30(H)) with Markus chamber(PTW, US) were used for dose measurement. This study was distinguished natural gauzes and spread over Vaseline gauzes. We gave variety to the gauze thickness at 5, 10 and 15 sheets respectively. For comparison between using bolus and not that, we had used 1.0 cm thickness bolus so that analyzed surface dose and PDD at the same conditions above mentioned. When maximum point was defined as reference point, surface dose was measured as $35\%$ in open beam. When the gauzes were attached to surface as 5, 10 and 15 sheets, surface dose were increased as 69, 80 and $91\%$ respectively according to thickness of gauzes. When spread over Vaseline gauzes were attached to surface as 5, 10 and 15 sheets, surface dose were increased respectively as 98, 100 and $98\%$ according to thickness of gauzes. Also when 0.5 cm bolus and 5 sheets gauzes were composed, surface dose was measured as $98\%$. The gauzes that were attached to skin surface in radiation therapy had been scattering material and contributed increasing surface dose without variation of percentage depth dose. However, if we want to delivery much dose to skin surface then we have to apply many sheets of gauzes to skin surface. Although we get easy that result by bolus or spread over Vaseline gauzes, we have to revise percentage depth dose at calculation. Therefore, if we find pertinent conditions based on measured data that are considered skin dose and patient setup efficiency, to replace custom bolus with gauzes will be helpful to efficient treatment.
