Purpose : In order to study the effectiveness of East-West pain treatment on central poststroke pain(CPSP), we evaluated its effect on alleviation of pain and rehabilitation of CPSP Patients who were treated with electroacupuncture and west pain treatment for four weeks. Methods : Twenty four patients diagnosed by their pain characteristics of central pain from stroke were treated with sympathetic nerve block, gabapentin, amitriptyline, and electroacupuncture for four weeks. Pain intensity through the visual analogue scale(VAS), and improvements of mobility and rehabilitation through the modified Barthel index(MBI) and Rankin scale(RS), respectively, before and after pain treatment were also assessed. Results : VAS pain scores were significantly improved from 7.7±1.7 to 4.4±2.0 with pain treatment(p<0.05). In accordance with improvement of pain scores, RS and MBI scores were also improved from 2.88±0.95 to 2.13± 1.01 and from 83.0± 16.9 to 94.7±9.5(p<0.05), respectively, with pain treatment(p<0.05). Conclusions : It was suggested that the active pain treatment was contributed to the rehabilitation of CPSP patients, resulting in improvement of quality of life of CPSP patients. Futhermore, East pain treatment in combination with West pain treatment may be useful modality to alleviate CPSP.

목적: 2000년도에 이황화탄소 중독증 환자들과 대조군의 심박동수 변이를 비교하여 이황화탄소 중독증 환자들의 심박동수 변이가 대조군에 비해 유의하게 낮다는 연구보고가 있었다. 당시의 연구가 이황화탄소 노출이 중단된 상태에서 이황화탄소 중독자들의 건강 문제를 연구했다는 점에 의의가 있으나 연구 결과를 해석하는데 있어 제한점들이 있었다. 이 연구는 2000년도에 수행하였던 연구의 제한점을 극복하고 이황화탄소 노출이 중단된 이후의 이황화탄소 중독자들의 심혈관계 상태를 심박동수 변이를 이용하여 평가해보고자 하였다. 방법: 이황화탄소 중독증으로 진단받은 환자 122명과 환자군의 연령대와 성별 빈도에 따라 무작위 추출한 112명을 대조군으로 선정하였다. 자기 기입식 설문지와 건강검진을 통해 연령, 성별, 신장, 체중, 흡연, 음주, 규칙적 운동, 질병력, 직업력, 흉부 방사선 촬영, 심전도 측정을 실시하였다. 연구 대상자들은 의자에 앉힌 상태에서 5분 동안 심박동수 변이를 측정하였다. 이 연구에서 측정한 심박동수 변이 지표들은 정상 RR간격의 표준편차(standard deviation of all norma-to-normal intervals, SDNN), 인접한 RR간격들의 차이를 제곱의 합의 평균의 제곱근(square root of the mean of the sum of squares of differences between adjacent normal-to-normal intervals, RMSSD). 저주파영역(low frequency power, LF: 0.04~0.15Hz), 고주파 영역 (high frequency power, HF:0.15~0.4Hz), 전체 주파수 강도(total power, TP), 저주파/고주파 비 (LF/HF ratio)이다. 결과: 단변량 분석에서 이황화탄소 중독자들의 모든 심박동수 변이 지표들이 대조군에 비하여 낮았다. 다중선형회귀분석에서 이황화탄소 중독은 RMSSD를 유의하게 감소시키는 것으로 나타났다.(P<0.05). 결론: 이 연구는 이황화탄소 노출이 중단된 상태에서도 이황화탄소 중독자들에게 심혈관계와 관련된 건강문제가 있을 수 있음을 시사한다. Objectives: A previous study conducted in 2000 measuring the heart rate variability (HRV) of carbon disulfide (CS_(2))-poisoned subjected suggested that their HRV was reduced after exposure cessation. However, the study was limited by the following procedural limitations: (1) only 71 CS_(2)-poisoned subjects participated, (2) no females participated, and (3) the CS_(2)-poisoned subjects were older than the controls. This study was therefore conducted to overcome these limitations of the earlier study. Methods: The study subjects comprised 122 retired workers with CS_(2) poisoning and the same number of age- and sex-matched controls. Information on individual age, sex, height, wight, smoking history, alcohol drinking, regular exercise, medical and occupational history, chest x-ray, and ECG recording of the two groups was collected though a self-administered questionnaire and a medical examination. Standard Deviation of NN intervals (SDNN), Root-Mean-Square of Successive Differences (RMSSD), Total Power (TP), Low Frequency (LF), High Frequency (HF), and LF/HF ratio were measured as HRV indices for 5 minutes in the sitting position. Results: Univariate analysis revealed that all HRV indices of CS_(2)-poisoned subjected were lower than those of the controls. Multiple linear regression analysis showed that CS_(2) poisoning had negative association with all HRV indices and that its association with RMSSD was statistically significant(P<0.05). Conclusions: This study suggests that CS_(2)-poisoned subjects continue to have reduced HRV, even though the exposure has ceased.

In this paper, we consider an n-job, non-preemptive and identical parallel machine scheduling problem of minimizing the sum of earliness and tardiness with different release times and due dates. In the real world, this problem is more realistic than the problems that release times equal to zero or due dates are common. The problem is proved to be NP-complete. Thus, a heuristic is developed to solve this problem. To illustrate its suitability, a proposed heuristic is compared with a genetic algorithm for a large number of randomly generated test problems. computational results show the effectiveness and efficiency of proposed heuristic. In summary, the proposed heuristic provides good solutions than genetic algorithm when the problem size is large.

Cosmetic parts such as side keys, navigator switches and Window frames in Cellular phone have been produced mostly by nickel electroforming. But nickel has an allergic reaction with skin. Copper is known to be the most promising alternative material for nickel. In this feasibility study of copper electroforming, copper plating bath type, its optimum composition and mechanical properties were studied. Chloride free-acid copper sulfate was found to be the most suitable bath compared with pyrophosphate and cyanide baths. Target hardness value of 200~220DPH could be obtained by adding 401/402 additives in copper sulfate bath. Another weakness of copper electroform is its poor corrosion characteristic. In order to increase its corrosion resistance, four types coating were applied on top of copper surface. They were Cu/Cu-Sn-Zn/Cr, Cu/Pd/Cr, Cu/Cu-Zn-Sn, Cu/Cr. Salt spray test showed that Cu/Cu-Sn-Zn/Cr did not show any pit after 72hours salt spray test.

Clinical reports have indicated that there occurs many bubbles on the surface of the gypsum model because of the hydrogen release from the addition silicone impression materials. Recently the products containing hydrogen absorber have been being developed but not perfect yet. In this study, 4 type Ⅲ dental stones(New fujirock ; G.C., New Plastone ; G.C., MG dental stone ; Maruishi, Suprastone ; Kerr) was poured into the impression of detail-reproducing test block taken using addition-type silicones (Correct VPS ; J/P, Exafine ; G.C., Express ; 3M, Extrude ; Kerr, Provil ; Bayer, Reprosil ; Dentsply) with the intervals of 0, 15, 30, 45, 60, 90 and 120 minutes. Gypsum model was removed from the impressions and the number of bubbles on the surface of casts was counted after 30 min. Ordinal numbers were given to the ranges of the number of bubbles like this, Score 0 ; 0, 1 ; 1∼10, 2 ; 11∼30, 3 ; 31∼60, 4 ; 61∼100, 5 ; 101∼200, 6 ; 201∼400, 7 ; 401 or more. There was no bubble in Correct VPS impression poured immediately in MG dental stone and Extrude impression poured immediately in New Fujirock, New Plastone, and MG dental stone. Significant bubbles were appeared in Provil until 15 minutes(Score 1∼3), Reprosil until 30 minutes(Score 1∼2), and Express until 45 minutes(Score 1∼2) in all gypsum models(p<0.05). Express impression poured in Suprastone(Score 2) and New Plastone(Score 4) had bubbles until 120 minutes(p<0.05). On the basis of this study it can be concluded that not only hydrogen release but also compatibility with gypsum should be considered when using addition silicones.
