대구효성가톨릭대 양재호교수는 인체 피부가 다이옥신에 민감하다는 사실에 착안하여 인체 피부세포를 모델로 사용하여 인체에서도 암을 유발한다는 사실을 증명한 과학자이다. 양교수의 연구결과는 다이옥신이 인체 세포에서 암을 일으킬 수 있음을 증명한 최초의 보고서로 평가되고 있으며 97년 세계보건기구 산하의 암연구기구도 다이옥신을 인체발암물질로 분류하는데 중요한 자료로 활용하고 있다.

본 논문은 여성들이 주로 걸리는 암에 대해 올바른 지식을 가지고 건강관리 할 수 있도록 하는 전용 어플리케이션을 만들어 주요 암에 대한 예방을 할 수 있도록 해준다. 특히, 암에 대한 중상 및 관련 동영상 등 일반 정보 뿐 만 아니라 자이로 센서를 통해 요가 자세 교정 등 건강관리를 해 주게 되며, 다이어리 기능을 통해 각자 개인에 맞는 식단을 짤 수 있고 예방접종 알림 서비스를 사용할 수 있게 한다. 즉, 질병과 관련된 많은 어플리케이션이 있지만 이 어플리케이션은 특히 여성을 위한, 암에 대한 주요정보를 제공하게 된다. 또한 단순한 정보 제공에 끝나는 것이 아니라 요가 기능과 다이어리 기능과 같이 사용자 개인 상황에 맞는 맞춤형 서비스를 제공하게 된다.

General information is summarized, that is necessary to introduce a scientific assessment of the human health and exposure issue concerning dioxin and dioxin-like compound. Scientific literatures were reviewed to assess the background exposures to the dioxin-like compounds for normal residents. Epidemiologic studies were also reviewed to assess malignant and nonmalignant sweets of dioxins. In 1997, the International Agency for Research on Cancer classified 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) as a human carcinogen, primarily based on occupational cohort studies. The US Environmental Protection Agency made the same decision in it's Draft Dioxin Reassessment. Epidemiologic evidences point to a generalized excess of all cancers, without any pronounced excess at specific sites. Reported non-cancer effects included a range of conditions affecting most systems. Among them, chloracne, elevation in gamma glutamyl transferase(GGT), and alterations in reproductive hormones are related to TCDO, Other adverse outcomes, such as lipid concentrations, diabetes, circulatory and heart diseases, immunologic disorders, neurobehavioral effects, and developmental outcomes require further study before their respective relationships to TCDD can be more definitively assessed.

본 논문에서는 저전압 구동 인버터의 게이트 구동회로 설계 시, 밀러 캡 영향이 야기할 수 있는 암 단락 현상 방지를 위한 양전원 방식의 게이트 구동회로 설계를 제안한다. 제안하는 회로는 부트스트랩 방식의 0~15[V] 의 전원을 사용하고, 커패시터와 다이오드를 통하여 마이너스 전압을 생성하며 이를 통해 양전원으로 게이트를 구동한다. 이는 단 전원 방식에 비하여 밀러 캡의 영향을 줄일수 있고 이를 통해 스위칭 시 소자의 스트레스를 감소시키며 또한 암단락을 방지한다. 제안하는 회로를 시뮬레이션과 실험을 통해 검증하였다.

A new type of Si diaphragm was fabricated using Si-wafer direct bonding and two-step electrochemical etch-stopping methods. Using the new diaphragm structure in mechanical sensors, more precise control of cavity depth and diaphragm thickness was achievable. Also, the propagation of the stress, which was generated near the bonding interface, to the surface can be avoided. Finally, a piezoresistive-type Si pressure sensor was fabricated utilizing the diaphragm and a digital pressure gauge, which can display units of pressure, was realized.

Ti/sic(4H) Schottky barrier diodes were fabricated. The donor concentration and the built-in potential obtained by capacitance-voltage(C-V) measurement was about $2.0{\times}10^{15}{\textrm}{cm}^{-3}$ and 0.65 V, respectively. The ideality factor of 1.07 was obtained from the slope of current-voltage(I-V) characteristics at low current density. The breakdown field under the reverse bias voltage was about $1.7{\times}10^3V/{\textrm}{cm}$ and was very high. The barrier height of Ti for SiC(4H) was 0.91 V, which was determined by the analysis of the saturation current-temperature and the C-V characteristics.

High-energy and high-dose X-ray and electron beam have been used in radiation therapy after developing particle accelerators. It is recommended to irradiate patients exect real dose for improving therapy effectiveness by International Committee on Radiation Units and Measurement. The radiation detector for daily beam checks of medical accelerators is described. Using thirteen silicon diodes, we have designed the diode detector providing information about calibration, beam symmetry, flatness, stability variation according to radiation damage, time and general quality assurance for both photon and eletron beams. we also compared these measurement values with those of using ionization chamber, film and semiconductor dosimeter.

Clinically applicable light emitting diode (LED) has been widely investigated because of relatively low heat generation, low cytotoxicity, and non-invasiveness compared to other therapeutic methods. Therefore, we investigated the therapeutic effects of several wavelengths of light emitting diode against human cervical cancer cells and analyzed the individual inhibitory effect for the cancer cell proliferation. In the experiment, prepared HeLa cells were exposed by red, green and blue light-emitting diode for 10 minutes each. Relatively short-wavelength light-emitting diode (blue) showed stronger therapeutic effects than relatively long-wavelength light-emitting diodes.
