1. Objectives This study aims to evaluate newly developing Sasang Constitution Diagnosis Questionnaire for accuracy and efficiency. 2. Methods Three hundred and twenty eight patients from 4 multi centers are involved in this study. Excluding 16 constitution-unidentified patients and 2 Taeyang-in patients, 310 patients' questionnaires are analyzed statistically by their constitutions. 3. Results Sixty one questions are statistically significant in whole 229 questions of Sasang Constitution Diagnosis Questionnaire. We have selected 30 questions from 61 questions by comparing total data from 4 multi centers with those of each center. Thirty questions are made up of 10 body shape questions, 10 appearance questions, 5 character questions and 5 symptom questions. 3. Conclusions There might be needs for revision of character and symptom questions. From results, we suggest to diagnose Sasang Constitution for screening by short-form questionnaire consisted of questions on body shapes and appearances.

고상 반응법을 통해 $La_{0.6}Sr_{0.4}Co_{0.2}Fe_{0.8}O_{3-{\delta}}$ 페롭스카이트계 산소투과 분리막을 제조하였으며, 미세구조에 따른 산소투과 특성 및 기계적 특성을 고찰하였다. 분리막의 미세구조는 소결온도 및 소결 유지시간을 달리함으로써 조절하였으며, 미세구조에 따른 평균 입경 및 상대밀도의 변화를 평가하였다. 입계 분율의 감소에 따라 산소투과유속이 증가하는 경향을 나타내었으며, 본 연구에서 고찰한 소결조건 중에서는 1300${\circ}C$에서 10시간 유지하여 제조한, 상대밀도가 높고 비교적 입경이 조대한 분리막 시편의 경우, 최대 0.37 ml/$cm^2$${\cdot}$min의 산소투과유속이 특정되었다. 파괴강도는 소결체의 상대밀도에 의존적이었으며, 파괴인성은 결정립의 크기에 따라 증가하는 경향을 나타내었다. Oxygen permeability and the mechanical properties of mixed ionic-electronic conductive $La_{0.6}Sr_{0.4}Co_{0.2}Fe_{0.8}O_{3-{\delta}}$ perovskite-type membrane, fabricated by solid state reaction, were investigated with regard to microstructure. The microstructure of the membrane was controlled by changing the sintering temperature and holding time. The average grain size and relative density were evaluated as a function of sintering conditions. As the fraction of grain boundary decreased, oxygen permeability showed a tendency to increase. Especially the maximum oxygen flux of 0.37 ml/$cm^2$${\cdot}$min was measured for the specimen sintered at 1300${\circ}C$ for 10 h, which has high density and relatively large grain size. Fracture strength was dependent on the relative density of sintered body, while fracture toughness increased with average grain size.

In a speed coding system using excitation source of voiced and unvoiced, it would be involved a distortion of speech quality in case coexist with a voiced and an unvoiced consonants in a frame. So, I propose TSIUVC(Transition Segment Including UnVoiced Consonant) searching, extraction ad approximation-synthesis method in order to uncoexistent with a voiced and unvoiced consonants in a frame. This method based on a zerocrossing rate and pitch detector using FIR-STREAK Digital Filter. As a result, the extraction rates of TSIUVC are 84.8% (plosive), 94.9%(fricative), 92.3%(affricative) in female voice, and 88%(plosive), 94.9%(fricative), 92.3%(affricative) in male voice respectively, Also, I obain a high quality approximation-synthesis waveforms within TSIUVC by using frequency information of 0.547kHz below and 2.813kHz above. This method has the capability of being applied to speech coding of low bit rate, speech analysis and speech synthesis.

Some important problems for the bimodal initial mass function(IMF) of field stars in the solar neighborhood, the relation of the IMF of field stars with the combined IMF of open star clusters and the time-dependent IMF of young star clusters are discussed particularly by comparing their observed and computed present day mass functions.

1. Objectives and Methods It has been examined 703 papers of Sasang Constitution Society published from 1989 to 2007. Among them, the study methods have been classified focused on 332 papers related to clinical research and the method of constitution diagnosis and subjects have been researched to research the reality of the clinical research of Sasang Constitutional Medicine. 2. Results 1. The rest studies are the most which can not be classified by existing study method among 332 clinical studies. 2. The study of patient control group is 17 cases and the clinical experiment is one case, so highly well-grounded studies have not been performed. 3. The most method of constitution diagnosis is the constitution diagnosis by experts and by QSCC. 4. The number of constitution diagnosis method performed in the research institution is within 2. They are 254 cases(89.5%). 5. The studies which utilize more than 3 constitution methods are 22 cases and the studies that use medical rash are 7cases(31.8) 6. The 215 cases that subjects are less than 100 are the most and 100${\sim}$500 subjects are 71 cases. 500${\sim}$10000 subjects are 33 cases and more than 1000 subjects are 15 cases. 3. Conclusions Therefore, it is needed to increase the rate of highly well-grounded studies and set the standard criteria by providing constitution diagnosis guideline.

If the proximal portion of the fourth segment of the vertebral onery is occluded before the posterior inferior cerebellar artery branch, ischemia usually affects the lateral medulla oblongata or the ipsilateral side of the cerebellum. The lateral medullary syndrome(wallenberg syndrome) resulting from occlusion in this area is common. 62 years old male who has swallowing difficulty, dizziness and diagnosed as the lateral medullary syndrome(wallenberg syndrome) is admitted in Wonkwang university oriental medical hospital Kwangju. We have diagnosed him as Taeumin and treated by east integrated therapy. We classified this as Taenmin-liyoiljung(太陰人 裏熱症) and prescribed chungsimyoinjatang(淸心蓮子湯) to the principle of cheongganjoyoil(淸肝燥熱). In the result, we had the improvement of the symptoms. This report described the process and contents about the way the patient was cured.

"Smart window"에 코팅재료로 쓰이는 thermochromic $Vo_{2}$박막을 전자빔 증착 방법으로 유리 기판위에 증착시켜 $0^{\circ}C$-$90^{\circ}C$ 온도범위에서 가시광 및 근적외선의 투과율을 spectrophotometer로 측정하였다. $300^{\circ}C$의 기판온도와 $400^{\circ}C$ 어닐링 온도가 $VO_{2}$ 박막이 결정화되기 때문인 것으로 확인되었다. 또한, $VO_{2}$박막을 알곤중에서 어닐링하면 500nm이하의 파장에서는 그 투과율이 상당히 낮아지는 것으로 나타났다. W가 5a/0첨가된 $V_{0.95}W_{0.05}O_{2}$박막은 약 $0^{\circ}C$의 천이돈도를 나타내었고 Sn이 0.5a/o $V_{0.995}W_{0.005}O_{2}$박막의 경우에는 $300^{\circ}C$의 기판온도에서 증착한 후 $450^{\circ}C$/5시간 동안 알곤가스 중에서 어닐링하였을때 뚜렷한 thermochromism을 나타내었으며 이 박막의 천이온도는 실용가능한 온도인 약 $25^{\circ}C$로 발견되었으며 약간의 이력곡선이 나타났다.력곡선이 나타났다. Thermochromic $Vo_{2}$ thin films for "smart windows" were prepared by electron beam evaporationmethod on a glass substrate and spectral transmittances were examined by spectrophotometer. Substratetemperature of $300^{\circ}C$ and annealing temperature of $400^{\circ}C$ were found to be effective to give athermochromism on $Vo_{2}$ thin film due to the crystallization of the thin film. Furthermore, annealing of$Vo_{2}$ thin film affected the spectral transmittance and reduced the transmittance significantly at wavelengthbelow 500nm.$V_{0.95}W_{0.05}O_{2}$ thin film doped by 5 atomic percent of W showed semiconductor-metal transition around 0$0^{\circ}V_{0.995}W_{0.005}O_{2}$thin film which contains 0.5 atomic percent Sn showed therrnochrornisrn when it was depositedat substrate temperature of $300^{\circ}C$ and annealed at $450^{\circ}C$ for 5 hours in argon gas. The transitiontemperature of the $V_{0.995}W_{0.005}O_{2}$ thin film was found to be about $25^{\circ}C$ and showed some hysterisis. and showed some hysterisis.
