Purpose : The purpose of this study is to compare muscle activity after applying two muscle energy techniques (MET) to subjects with forward head posture to see if the post isometric relaxation (PIR) technique is more effective than the reciprocal inhibition (RI) technique. Methods : The muscle activity was measured using EMG after applying the PIR and RI techniques to 30 adults at K College. Subjects were selected for forward head posture whose ear center was 2.5 ㎝ front of the center of the shoulder. EMG equipment was used to measure muscle activity, and the measurement sites were measured in cervical flexor and extensor muscles. The experiment period was performed once a week for a total of two weeks, and after the pre-measurement was performed for 5 minutes PIR and RI exercise. In the PIR technique, the head is tilted back in a sitting position, and the experimenter applies resistance with the same force for 7~10 seconds and repeats 3-5 times after rest. In the RI technique, in a sitting position, the subject gives the force to bend the head forward, and the experimenter applies resistance with the same force for 7 to 10 seconds, and repeats 3 to 5 times after rest. Results : The result is same as the following. In the comparison of muscle activity, there was a significant decrease in both PIR and RI at 1 and 2 weeks. And there was a greater decrease in muscle activity in PIR. There was no difference in the comparison of decrease in muscle activity at 1 week and 2 week. Conclusion : Both PRI and RI can be said to be effective in improving the function of the forward head posture in the neck muscles. Therefore, the selection of the two techniques in clinical practice should be appropriately performed under the judgment of experts according to the patient's situation.

Bacteriophage P4, a satellite phage of coliphage P2, is a very useful experimental tool for the study of viral capsid assembly and cos-cleavage. For an in vitro cos-cleavage reaction study of the P2-P4 system, new shortened and selectable markers containing P4 derivative plasm ids were designed as a substrate molecules. They were constructed by swapping the non-essential segment of P4 DNA for either the kanamycin resistance (kmr) gene or the ampicillin resistance (apr) gene. The size of the genomes of the resulting markers were 82% (P4 ash8 delRI:: kmr) and 79% (P4 ash8 delRI:: apr) of the wild type P4 genome. To determine the lower limit of genome size that could be packaged into the small P4-size bead, these shortened P4 plasmids were converted to phage particles with infection of the helper phage P2. The conversion of plasmid P4 derivatives to bacteriophage particles was verified by the heat stability test and the burst size determination experiment. CsCl buoyant equilibrium density gradient experiments confirmed not only the genome size of the viable phage form of shortened P4 derivatives, but also their packaging into the small P4-size head. P4 ash8 delRI:: apr turned out to be the smallest P4 genome that can be packaged into P4-sized head.

Objectives: The response rate of the radioactive iodine(RI) therapy with low dose was variable. Only a few studies reported the response and complication rate with high dose. The goal of this study was to access the ablation and complication rate after high dose of RI therapy (more than 100mCi) and to evaluate the factors affect the results. Material and Methods: During a period of 12 years, 225 patients received high dose of RI from 100 to 200mCi depending on the RI uptake in the whole body after total thyroidectomy. 100mCi of RI was given to 123 patients for ablation who showed the uptake only in the thyroid bed. 150mCi was given to another 84 patients for ablation who had uptake confined to the neck. The other 21 patients took more than 200mCi of RI because the whole body scan showed distant metastasis. Among these patients, the ablation and the complication rate was investigated. Results: Elevated level of the serum thyroglobulin(Tg) decreased less than 5ng/ml after RI therapy in all patients except two in the first group. The second group showed reduction of the serum Tg in 93%. Eighteen of the 21 patients in the third group are still alive after RI therapy. There were no fatal complications after high dose RI therapy and most of the complications were minimal and transient. The complication rate was not related with the dose of RI, age, sex, DNA flowcytometry, serum thyroglobulin level and the extent of node dissection. Conclusion: We concluded that RI therapy with high dose was very effective for thyroid ablation after operation and it also showed excellent results with minimal complications for treatment of metastatic lesions.

P2-크기 머리에 packaging 될 특정 DAN 크기(28-29 kb long)와 박테리오파지 P4 유전자 sid의 변이가 "P2 sir-관련 도움파지 비효율성"을 극복할 수 있는 요소로 압축되었다. 유전자 sid의 변이 여부가 필수적인지를 확인하기 위해, 정상적인 sid 유전자를 가지며 $P2_{sir3}$-크기의 큰 머리에 packaging 될 DNA 크기가 28.5 kb되는 P4 delRI::kmr을 사용하여 실험하였다. P4 delRI::kmr이 P2 sir3 용원소에 대해 낮은 EOP를 보이므로, 이를 증가시키기 위해 P2 sir3 용원소를 숙주세포로 하여 파지 stock을 제조하였다. 이 과정에서 P4 delRI::kmr이 P2 sir3 용원소에 대해 적응하는 것을 관찰하고, CsCl 부양 균등밀도 편차실험과 분리된 DNA의 전기영동을 통해 그것이 packaging 될 머리 크기에 따른 DNA 형태 변화에 의한 적응이라는 것을 알아냈다. P2 sir3 용원소에 적응된 P4 delRI::kmr과 적응되지 않은 P4 delRI::kmr stock의 burst size 결정 실험은, sid 유전자 변이에 상관없이 packaging 될 DNA 크기에 의해 "P2 sir-관련 도움파지 비효율성"이 극복된다는 것을 보여주었다.

Objectives: The clinical efficacy of the color and pulsed Doppler ultrasound with spectral waveform analysis for differentiation of malignant from benign cervical lymphadenopathy was prospectively evaluated in cervical lymphadenopathy. Materials and Methods: Color and pulsed Doppler ultrasound examination was prospectively performed in 32 cervical lymph nodes in 28 patients. These 10 nodes from 10 patients were malignant and 22 nodes from 18 patients were benign, proved by operation, biopsy, and follow-up examination. Another 12 lymph nodes from 12 normal volunteers were evaluated as control group. The peak systolic velocity (PSV), minimal diastolic velocity (MDV) , and resistive indexes (RI) of arterial flows within the 32 lymph nodes were assessed to differentiate the malignant from benign nodes with pulsed Doppler ultrasonography. The results were qualitified with one-way ANOVA and Bonferroni method of multiple comparison. Results: The mean values of PSV of malignant, benign, and control nodes were 38.2(10.1-134)cm/sec, 23.3(9-38.5) cm/sec and 11.8(6.7-18.1) cm/sec, respectively. The mean values of MDV of them were 0.9(-7.5-10.7)cm/sec, 9.7(2.9-18.6)cm/sec and 6.5(3.7-9.3)cm/sec, respectively. However, there was no statistical significance in differentiation of malignant from benign nodes with PSV and MDV. The mean values of RI of malignant, benign, and control nodes were 0.99(0.80-1.30), 0.59(0.46-0.77) and 0.45(0.38-0.50), respectively. RI value of 0.8 is suggestive value for discrimination of malignant from benign lymphadenopathy during examination of color Doppler ultrasound of cervical lymphadenopathy. Conclusion: Color and pulsed Doppler ultrasound examination with spectral waveform analysis may be quite helpful in the differentiation between benign and malignant alterations of cervical lymph nodes.

The purpose of this study was to identify and to trace the source of origins of 麻帝核試 that appears in Kei Rim Yu Sa(鷄林類事). Comparative liguistic analytical approaches ware employed for this study. Results of this study revealed that madi(마디) survives as a dialect for m ∂ri[머리(頭)] in Kyung Sang Province Thus, it si considered that the dialect madi(마디) is a survival of 마디(麻帝) of Koryo. Similar words to 核試 of Koryo were found in Hebrew and Japanese : Heb. k-u-tsi(zi) means locks of hair and Japanese ku-shi(くシ) has several meanings : comb, head, and the hair of the head. The word 麻帝核試 of Koryo is a compound ward of madi(麻帝), head and k ∂ shi(그시) 核試 locks of hair(hair of the head). 核試 of Koryo , Jao. ku shi(くシ), and Heb. k-u-tsi(zi) showed close relationships to one another. The word ku shi(si) 그시 核試 was derived from Heb. k-u-tsi(zi) and Jap. ku shi(くシ) was originated from 核試 of Koryo. Kor. ku shi(si) 그시 核試 is a transliteration of Heb. k-u-tsi(zi) and Jap. ku shi(くシ) is a trans-literation of Kor. ku shi 그시 核試.

A 50-year-old Korean female with oral erythro-leukoplakia was treated using a 532-nm Diode laser at 6 Watts with a pulsed width of 25 milliseconds. After two months following the laser treatment, the resected region was well-healed without any significant scar contracture. We suggest that the use of the 532-nm Diode laser can be a safe and effective treatment modality for patients suffering from oral leukoplakia.

Differentiated thyroid carcinomas are rarely associated with macroscopic vascular invasion and intraluminal tumor thrombus in great cervical veins. The best treatment for such cases appears to be a total thyroidectomy with en-block resection of the involved vessels, followed by postoperative radioiodine therapy(RI). We report two cases of follicular thyroid carcinoma with vascular invasion and intraluminal tumor thrombosis in great cervical veins that were successfully treated using complete surgical resection and postoperative RI.
