PURPOSE : The 3rd molar extraction of mandible is common in out-patient office of oral and maxillofacial surgery. And it is dynamic minor operation with changes of vital signs. most of patients are already sensitive about their dental treatment. The changes of emotion are reached to the highest level when patients is laid down to be treated on unit chair. It can be induced to undesirable accidents as to this fear. The undesirable complications are nausea, vomiting, hyperventilation, dyspnea, syncope, shock and so on. The severe changes of vital signs may influence their behavior and make serious medical malpractice or suit such as fracture of dental instruments and injury of proximal area. METHOD AND PATIENTS : A total of 99 selected normal patients were reviewed. Among this, 70 patients(43 men, 27 women with statistical significance) were included in this study. Each steps(pre-anesthesis, 5 minutes after anesthesis, just after mucogingival incision, just after tooth section, just after suture and gauze biting) were investigated for a change of a vital signs. It is analyzed to 2 categories,"Means" and "Tendency". The "Means" is the amount of vital signs changed in comparison with pre-step during operation. That means is the amount of vital changes by each step operation. Next, " Tendency" is changes of vital signs in comparison with step1 during operation. RESULT : This is the changing tendency of vital signs with time. That is active effect of fear and pain. Thus this "Means" and "Tendency" will present a sudden changes of vital signs and it can lead to more safe treatment. CONCLUSION : Thus, the purpose of this study is, through careful operation in each step, to less on patients' complication and increase trust between patient and OMFS. This study is a first article shown with the amount of "Means" and "Tendency" in vital signs, when a third molar of mandible is extracted. This study will be base study of patients with general diseases, because it selected only patients without general diseases.

미디어 이미지는 변화를 계속하고 있다. 그에 따라 이미지는 다양한 분야에서 다른 방식으로 만들어지고, 재생산되고 있다. 이미지의 생산과 소비에 관한 패러다임은 점점 가속화되고 순환하고 있다. 이미지의 생산과 소비에 관한 관계 또한 변화하고 있으며, 생산자와 소비자의 경계 또한 모호해져 가고 있다. 미디어 이미지가 보여주는 다른 이미지의 차용이나 변형은 오랫동안 커뮤니케이션의 주요 수단으로 사용되었던 문자나 부호, 기호마저도 본연의 의미를 상실하고, 새로운 이미지 표현 수단 및 미학적 표현으로 사용되고 있다. 따라서 본 논문에서는 기호의 하나인 등고선을 이용하여 새로운 미학적 표현 수단으로 발전시키고자 하였다. 또한 그 방법에 있어서, 이미지의 생성에 소비자를 적극적으로 개입시켜 이미지 소비자와 생산자와의 관계를 변화시켜, 일방적인 소비와 생성의 관계가 아닌 소비자가 이미지를 생성시키는 주체로 작용시키고자 하였다. 즉, 기능적인 역할의 등고선을 본연의 의미를 상실시켜 새로운 미학적 표현의 방법으로 등고선을 이용한 라인드로잉의 이미지를 생성하고, 시간과 관객의 행동에 따라 끊임없이 재생성 되어 관객이 이미지의 생성에 직접적으로 작용하고자 한다. 이것은 기호를 커뮤니케이션을 위한 약속으로 바라보는 고정적 시각에서 벗어나 미학적 표현 가능성을 보여주고, 지형에 대한 새로운 인식을 환기시키고자 한다.

The objective of this retrospective study was to evaluate whether the transvaginal ultrasonographic analysis of endometrial pattern and thickness could predict the stage of menstrual cycle. Endometrial pattern and thickness were observed in those patients receiving infertility work up from April, 1994 to July, 1998 at Seoul National University Hospital. The study group was 185 patients with normal regular menstrual cycles. Among them, 44 patients received endometrial biopsy, and the date of endometrium was compared with the observed endometrial pattern and thickness. The observed endometrial pattern was presence or absence of central cavity echogenicity, triple line sign, endometrial hypoechogenicity, ring sign, endometrial hyperechogenicity and posterior acoustic sonic enhancement. The results were as follows; Central cavity echogenicity was seen throughout menstrual cycle. Triple line sign was observed in 81.1% of patients during early secretory phase. However, in mid to late secretory phase, triple line sign was appeared in only 6.8%. The percentage of positive endometrial hypoechogenicity was highest in early secretory phase. In contrast to hypoechogenicity, positive endometrial hyperechogenicty was highest in mid to late secretory phase. Ring sign was observed in 73.5% of the patients during early secretory phase with peak incidence. Posterior acoustic enhancement was seen in 72.7% of the patients during late secretory phase. The sensitivity and specificity of being a secretory phase if the patients showed hyperechogenic endometrium, were 84.2%, 83.3% respectively. The sensitivity and specificity of being a secretory phase if the patients showed posterior acoustic enhancement were 93.8%, 58.3% respectively. Endometrial thickness was not correlated with endometrial dating. In conclusion, transvaginal ultrasonographical delineation of the endometrial pattern might be useful tool in predicting endometrial status during normal menstrual cycle. But, endometrial thickness could not predict the endometrial dating.

Objectives : The purpose of our study was to compare findings of brain SPECT representing crossed cerebellar diaschisis(CCD) with brain MRI, to evaluate relation between CCD and location of lesions on MRI and to elucidate clinically apparent cerebellar sign in patients with CCD. Methods : The study population was 20 patients representing CCD on SPECT. Percentage differences(${\triangle}%$) of activity on each cerebellar hemisphere were obtained from ipsilateral and contralateral cerebellum[${\triangle}%cbll=(IL-CL)/IL{\times}100$] and from cerebrum [${\triangle}%cbr=(CL-IL)/CL{\times}100$]. From MR studies, the percentage differences of signal intensity were also calculated as the same method. We compared the degree of percentage differences with location of cerebral lesions and with clinical cerebellar signs of the patients. Results : Among those representing CCD, the parietal lesions were the most common. There was significant correlation of the percentage differences in cerebellum between SPECT($18.8{\pm}7.22$) and MRI($4.4{\pm}3.38$) (p<0.05) and in cerebrum between SPECT($28.7{\pm}15.35$) and MRI($42.8{\pm}10.94$) (p<0.05). Cerebellar signs were observed in 3 of the 20 patients. However, there was no statistically significance between degree of percentage differences of each cerebellar hemisphere on SPECT and clinical cerebellar sign(p>0.05). Conclusion : Using the percentage differences in the cerebellum, the CCD evaluation can be easily done. On MRI, the signal changes of cerebellum were not as definite as SPECT. Despite of our assumption, there was no significant correlation between clinical cerebellar signs and CCD on SPECT.

뉴 미디어를 비롯한 신문지상과 TV에서 날마다 쏟아있고 있는 정보의 확산은 점차로 소비자의 의식을 새로운 가치관으로 이끌어가고 있으며 또 소비적 성향을 그 제품이 주는 실용성이나 경제성이라는 가치보다는 감성적 욕구로서의 기호 가치로서 제품의 가치를 인식하게 하고 있다. 가치관과 의식의 변화는 디자인에 많은 변화를 초래했는데 그 변화를 살펴보면 획일적이고 일방적이었던 모던 시대의 디자인에서 다의적이고 다중 적으로, 상품 소비에서 기호 소비 또는 이미지 소비로 물건의 외면 성, 현시성에 대립되는‘상품의 내면화’를 추구하게 되었으며, 유행 위주의 대중 소비에서 개성 중심의 개인 소비 성향으로서 변화이다. 이것은 기호 소비자의‘디자인 의미 해독’범위가 다양해지고 있음을 의미한다. 기호는 담론(discourse)을 옮기는 커뮤니케이션의 형태이며 담론은 의미 생성자와 의미소비자간의 커뮤니케이션에 관한 것을 말한다. 이 논문에서는 담론으로서의 기호 표현을 살펴보는 첫 단계로 광고의 기호 표현을 통해 직접적 표현의 경우, 은유적 표현의 경우로 나누어 생각해 보았다. 그리고 그 중 포스트모던의 성향을 표현하기에 적합하다고 판단되는 은유적 기호 표현에 대해서 좀더 깊이 있게 분석해 보고자하였다.

Objectives : This study is to report the effect of Korean medical treatment on a patient suffered from carpal tunnel syndrome (CTS) occurred in pregnancy and worsened after birth. Methods : We treated the patient diagnosed as carpal tunnel syndrome by Korean medical treatment such as acupuncture, pharmacopuncture and herbal medicine at ⃝⃝Hospital of Korean Medicine from July 31th 2015 to August 6th 2015. And we evaluated changes of symptoms by Visual Analog Scale (VAS), Tinel sign, Phalen’s test, and Digital Infrared Thermographic Imaging (DITI). Results : 1. Through Korean medical treatment, postpartum carpal tunnel syndrome was significantly improved. VAS was decreased from 4 to 2, Phalen’s test was manifested from 10 seconds to 26 seconds and Tinel sign was changed from positive to negative. 2. We compared the gap of temperature between palm and forearm before and after Korean medical treatment through DITI. The temperature on the right side was changed from 0.74℃ to 1.01℃ and the left one from 0.63℃ to 1.01℃. Conclusions : This case report shows that Korean medical treatment is useful to treat pregnancy-related carpal tunnel syndrome worsened after birth.

The reactions of bis(Y-aryl) chlorothiophosphates (1) with substituted anilines and deuterated anilines are investigated kinetically in acetonitrile at $55.0^{\circ}C$. The Hammett plots for substituent Y variations in the substrates show biphasic concave upwards with a break point at Y = H. The cross-interaction constants (${\rho}_{XY}$) are positive for both electron-donating and electron-withdrawing Y substituents. The kinetic results of 1 are compared with those of Y-aryl phenyl chlorothiophosphates (2). The cross-interaction between Y and Y, due to additional substituent Y, is significant enough to result in the change of the sign of ${\rho}_{XY}$ from negative with 2 to positive with 1. The effect of the cross-interaction between Y and Y on the rate changes from negative role with electron-donating Y substituents to positive role with electron-withdrawing Y substituents, resulting in biphasic concave upward free energy correlation with Y. A stepwise mechanism with a rate-limiting leaving group departure from the intermediate involving a predominant frontside attack hydrogen bonded, four-center-type transition state is proposed based on the positive sign of ${\rho}_{XY}$ and primary normal deuterium kinetic isotope effects.

Previous research has explored early expression of fire signs before the burning of insulation. To achieve this, typically, automatic inspections are used to detect gas emitted from odor capsules at electrical connection points; additionally, early fire signs can be expressed using visual inspection of changes in the appearance of temperature caps. However, early detection of electrical fire is often difficult because only specific inspections, which are not complex, are performed. Therefore, in this paper, we present complex inspection techniques, such as visual inspection, odor inspection, and automatic inspection, and propose a showing material of fire signs that can solve conventional problems. In addition, this study examines the conditions under which the candidate material for the showing material is designed, the composition of the candidate material selected based on the designed conditions, the manufacturing means used to produce the showing material considering the temperature for early expression of fire signs, and the performance of the produced showing material. Furthermore, we analyze various effects that can occur through the proposed display material.

This study was undertaken to find out the effect analysis of conservative treatment in of lumbar intervertebral disc. The data was performed to evaluate the effect of conservative treatment in 50 patients aging from 20 to 67 with lumbar intervertebral disc patients. Changes in low back pain score were evaluated by age, occupation, duration of symptoms, marital status, education period, self assessment. Duration of symptoms in over 7 months was 62.0%. 8.6 scores of complete recovery was changes in low back pain score of self assessment patients. In the multiple regression of risk factors to changes in low back pain score were correlated with age, education period, marital status, duration of symptoms(p<0.05). All patients were assessed by the low back pain protocol which was composed of symptom, clinical sign and activities of daily living scales before and after the treatment. Poor result could be predicted after the nonoperative treatment in the patient groups of changes low back pain score decreased with aging, duration of symptom over 7 months.
