Objectives : The purpose of this study is what Saamchimbeop's method of reinforcement and reduction. Methods : 1. We reffered to the Bo-Sa method of DongeuiBo-gam(東醫寶鑑), Uihakim-mun(醫學入門), Uihakjeong-jeon(醫學正傳), Chimgugyeongheom-bang(鍼灸經驗方), Biaoyou-fu(標幽賦) in Cimgudaeseong(鍼灸大成), Nei-Jing(內經). 2. We make a conjecture that Zheng(正), Ying(迎), Sui(隨), Xie(斜) Yingzheng(迎正), Duo(奪), Zhenghuoxie(正或斜), Wen(溫), Liang(凉), JongYang-Inyin (從陽引陰) in Saamchimbeop are another expression of method of reinforcement and reduction and compared with the method of reinforcement and reduction of DongeuiBo-gam(東醫寶鑑), Uihakim-mun(醫學入門), Uihakjeong-jeon(醫學正傳), Chimgugyeongheom-bang(鍼灸經驗方), Biaoyou-fu(標幽賦) in Cimgudaeseong(鍼灸大成), Nei-Jing(內經). Results : 1. Zheng(正) and Xie(斜) are angle of acupuncture manipulation. The descending inserting of Yang-meridian is acupuncture manipulation for the Tonifying effect(補法) and the direct inserting of Yin-meridian is the Dispersing effect(瀉法). 2. JongYang-Inyin(從陽引陰) is the contralateral acupuncture. 3. Ying(迎) and Sui(隨) in the Saamchimbeop are same meaning the method of reinforcement and reduction(補瀉手技法). 4. Saamchimbeop's the final aim is the Wen-Liang(溫凉) according to the disease strong and weak in the Ohaeng-seo of Saam-acupuncture. Conclusions : Saamchimbeop's method of reinforcement and reduction is reinforcement-reduction by lifting and thrusting the needle, breathing reinforcement-reduction method, reinforcing and reducing achieved by rapid and slow insertion and withdrawing of the needles, reinforcement and reduction by opening and closing of needles with contralateral acupuncture by Yin-meridian or Yang-meridian. Saamchimbeop's the final aim is the Wen-Liang(溫凉) according to the disease strong and weak.

Objectives: The subject of this research is the catechism on medicine between the doctors of Joseon and Japan in the 18th century through Choson Delegation(朝鮮通信使 ). Methods: The author intended to review and analyze the contents of catechism related to Acupuncture and Moxibustion and determined the characteristics of Joseon and Japan ?s Acupuncture and Moxibustion. Results: At the time, Japanese doctors had a grasp on most theories of Acupuncture and Moxibustion and were very specialized clinically. They usually used filiform needles with various techniques, and already they had many different schools in practice. However, they wanted to know if their Acupuncture and Moxibustion skills were up to the international standard, especially to Joseon, whom they regarded as a country advanced in Acupuncture and Moxibustion. They wanted to com- pare and contrast their Acupuncture and Moxibustion with Joseon's. 18th century Joseon was high time for Acupuncture and Moxibustion. Various tools were used in surgery, and varieties of needles were used to stimulate acupuncture points. The development of tools evinces the precision of Joseon's Acupuncture and Moxibustion at the time. Also, comprehensive works such as DongUiBoGam(東醫寶鑑) and UiHaklpMun( 醫學入門) greatly influenced Acupuncture and Moxibustion. Because of this impact, it can be deduced that Acupuncture and Moxibustion emphasizing Jang(臟) and Bu(腑) organs and Internal Injury developed greatly. In addition, acupuncturist Holm(許任)'s fame continued from the 17th century into the 18th century, and his medical practice left a huge mark on not only Joseon but other eastern Asian countries as well. Conclusions: We found out the evidences that there were a lot of exchanges of acupuncture and moxibustion between Korea and Japan based of the Joseon TongShinSa (Emissary)'s record of catechism on medicine in the 18th century.

Unlike a printing process, it is difficult to pattern organic thin films in the longitudinal (coating) direction using a coating process. In this paper, we have investigated the feasibility of patterning organic thin films using needles. To this end, we have slot-coated an aqueous poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate) (PEDOT:PSS) solution in the form of a fine stripe or large area and then applied the dual needle; one for discharging the main solvent of the underlying thin film and the other for sucking the dissolved thin film. We have found that the pattern width and depth increase as the moving speed of the plate decreases. However, it is observed that the sidewall slope is very gentle (the length of the slope is of the order of 200 ㎛) due to the fact that the discharged main solvent is widely spread and then isotropic etching occurs. With this scheme, we have also demonstrated that a fine stripe can be obtained by scanning the dual needle closely. To demonstrate its applicability to solution-processable organic light-emitting diodes (OLEDs), we have also fabricated OLED with the patterned PEDOT:PSS stripe and observed the insulation property in the strong light-emitting stripe.

The purpose of this study was to identify the effect of hand acupuncture for reduction of dysmenorrhea. 71 female middle school and high school students were selected as subjects from April to May 2001, among which 38 students consisted of the experimental group while 22 students were the control group by convenient assignment. The experimental group participated in hand acupuncture treatment. The experimental treatment was to puncture corresponding points(A4, A5, J1, J3, J23, H2, F7) on both the palm and back of a hand with disposable acupuncture needles and to remove needles after 20-30 minutes' recess during which the subjects reposed themselves on bed. The collected data were processed using the SPSS PC Program and analyzed using $X^2test$ and The results of this study were as follows 1. The symptoms of premenstrual syndrome have decreased, but no significant differences were statistically observed between hand-acupunctured group and non-hand acupunctured group. 2. Subjective pain degree has decreased after hand acupuncture. 3. As for objective pain degree, a significant reduction in voice change was observed between two groups. Facial expressional changes and perspiration degree reduced but showed no significant statistically changes between two groups. 4. Comfort has increased after hand acupuncture. These results suggest that the hand acupuncture therapy works effectively on easing menstrual pain and symptoms as well as partially on reducing discomfort. It is particularly efficacious for a reduction in subjective pain and facial expressional changes in positive respect. Therefore the hand acupuncture therapy can be considered as an independent nursing intervention for dysmenorrhea reduction.

Objectives : A previous study demonstrated that the connecting points of three yang meridians attenuated changes of nNOS, and Norepinephrine(NE) in rats. The current study investigated the changes in nNOS, NO and NE upon the needle insertion at varying depths at the connecting point of three yin meridians of the hand. Methods : Needles were inserted into rats, on both left and right sides of the connecting point, including the LU7, HT5 and PC6 acupoints which are three yin meridians of the hand. After insertion, needles were retained for five minutes. Each acupuncture groups were treated acupuncture at each acupoint and at the depths of superficial, middle and deep layer. After the retention, blood was drawn via cardiac puncture, and tissues of each point near meridian vessel was extracted to examine the changes in the expression of nNOS, NO and NE. Results : Compared with the superficial layer group, nNOS production significantly decreased in the middle and deep layer at LU7 acupoint group and in the deep layer at HT5, PC6 acupoint group. The tissue NE decreased in the deep layer on PC6 acupoint and the plasma NE increased at the middle layer at LU7 acupoint group but decreased at the deep layer on at LU7 acupoint group. Conclusions : Acupuncture at connecting points of three yin meridians of the hand can regulate the activities of nNOS, and NE.

Background: This study aimed to determine the prevalence and factors related to needle stick injuries (NSIs) and to assess related safety measures among a sample of Iranian nurses. Methods: In this cross-sectional study, a random sample of 168 registered active nurses was selected from different wards of one of the hospitals of Shiraz University of Medical Sciences (SUMS). Data were collected by an anonymous questionnaire and a checklist based observational method among the 168 registered active nurses. Results: The prevalence of NSIs in the total of work experience and the last year was 76% and 54%, respectively. Hollow-bore needles were the most common devices involved in the injuries (85.5%). The majority of NSIs occurred in the morning shift (57.8%) and the most common activity leading to NSIs was recapping needles (41.4%). The rate of underreporting NSIs was 60.2% and the major reasons for not reporting the NSIs were heavy clinical schedule (46.7%) and perception of low risk of infection (37.7%). A statistically significant relationship was found between the occurrence of NSIs and sex, hours worked/week, and frequency of shifts/month. Conclusion: The study showed a high prevalence of NSIs among nurses. Supportive measures such as improving injection practices, modification of working schedule, planning training programs targeted at using personal protective equipment, and providing an adequate number of safety facilities such as puncture resistant disposal containers and engineered safe devices are essential for the effective prevention of NSI incidents among the studied nurses.

Objective : The primary aim of this investigation was to explore the nature of dura mater biomechanics following the introduction of puncture defect(s). Methods : Twenty-eight dura mater specimens were collected during autopsy from the department of forensic medicine of the authors' institution. Specimens were divided randomly into one of four groups : group I (cranial dura mater; n=7), group II (cranial dura mater with one puncture defect; n=7); group III (cranial dura mater with two puncture defects; n=7), and group IV (cranial dura mater with three puncture defects; n=7). Results : The mean${\pm}$standard deviation tensile strengths of the dura mater were $8.35{\pm}3.16$, $8.22{\pm}3.32$, $7.13{\pm}1.77$, and $6.94{\pm}1.93MPa$ for groups I, II, III, and IV, respectively. There was no statistical difference between all groups. A single, two or more punctures of the dura mater using a 20-gauge Quincke needle did not affect cranial dura tensile strength. Conclusion : This biomechanical study may contribute to the future development of artificial dura mater substitutes and medical needles that have a lower negative impact on the biomechanical properties of dura mater.
