차세대 반도체 생산을 위한 450㎜ 웨이퍼 제조공정의 가장 큰 특징은 모든 제조공정이 완전자동화로 이루어진다는 것이다. 이러한 완전자동화로 인해 작업자의 공정개입이 불가능하게 되고 개별 웨이퍼의 중요도가 증가하므로 완전자동화를 지원할 수 있는 보다 우수한 스케줄링 방법과 시스템이 요구된다. 즉, 450㎜ 웨이퍼 생산을 위한 스케줄링 시스템은 개별 웨이퍼와 클러스터 장비의 공정 상태를 실시간으로 반영하여 생산성을 향상시킬 수 있는 견고한 스케줄링 기법을 적용해야 한다. 본 연구에서는 450㎜ 웨이퍼 생산환경에서 중요하게 사용되는 클러스터 장비와 그 특성들을 소개하고 timetabling 방법에 기반을 둔 효과적인 실시간 스케줄링 기법을 제시하고자 한다. 특히 웨이퍼가 공정완료 이후 chamber에서 일정한 시간동안 대기할 수 있는 웨이퍼 이동지연을 고려하여 FOUP 단위의 사이클 타임(cycle time)과 개별 웨이퍼의 공정 시작시간을 결정할 수 있는 방법을 제시한다. In the next generation fab environment for 450㎜ wafer production, one of the most significant features is the adoption of full automation to the whole manufacturing processes involved. So, it is necessary to construct more robust scheduling system for the entire semiconductor manufacturing processes since the full automation system prevents the process engineers from intervening the manufacturing processes as much as possible and the importance of each individual wafer noticeably increases. The scheduling system for 450㎜ wafer production also should be capable of monitoring the status of each individual wafer and collecting useful fab data in real time. In this study, we first introduce the cluster tool mainly used in 450㎜ wafer production, and then propose an effective real-time scheduling algorithm based on the timetabling method. Especially, our method considers the case that the wafer is assumed to be able to stay at the current chamber prior to proceed to the next chamber for a while, which increases the flexibility to assign the starting times of the processes.

Objective: To assess the changes of autonomic nervous system in the patients with central and peripheral nervous system lesions using sympathetic skin response(SSR). Method: 55 patient group consisted of 18 stroke, 20 radiculopathy, 10 spinal cord injury, 5 carpal tunnel syndrome and 2 traumatic brain injury. Control group consisted of 22 healthy subjects without neurologic disease. Electrical stimuli were applied over the median nerve at wrist and SSR were recorded simultaneously on bilateral palms and soles. SSR that was not evoked by 5 times of stimulation was considered as no response. Results: 1) 27.7 percent of the patients with stroke and 60 percent of the patients with spinal cord injury showed no response. 2) The amplitudes of SSRs recorded in the affected palms of stroke patients were significantly smaller than these of control group (P<0.05), regardless of stimulation side. 3) The amplitudes of SSRs recorded in the unaffected palm of stroke patients when stimulus was given to the affected side were smaller than these of control group (P<0.05). 4) In the patients with radiculopathy and carpal tunnel syndrome, the latency and amplitude of SSR showed no significant difference compared with these of control group (P>0.05). Conclusion: In central nervous system lesion, the abnormal findings of SSR reflected abnormal ascending and descending pathways of autonomic nervous system. In the patients with radiculopathy, the autonomic nervous system seemed to be maintained normally.

저자들은 간 절제술을 받은 49명의 환자를 대상으로 Ang, p53, CD34를 포함한 여러 임상병리학적인 인자들이 환자의 예후에 미치는 영향을 연구하였다. 14종류의 임상 병리학적인 인자들을 분석하였으며 생존율 계산은 Kaplan-Meier 방법을 이용하였다. 단일변수 분석을 하였을 때, 간경변을 동반 하지 않는 경우, 수술 전 측정한 AFP의 혈 청치가 200 ng/ml 이하인 경우, Child-Pugh`s 본류법상 A 또는 B 등급인 경우, 수술 후 병기가 1 혹은 2 인 겨우 및 와 복수를 동반하지 않았을 때 간세포암의 절 체 후 환자의 생존율이 높았다. 그러나 종양 내 혈관 밀도 측정의 지표인 CD34에 대한 면역조직화학 염색결과에 따라 분류한 환자군과, 암 억제 물질인 p53에 대한면역염색결과에 따라 분류한 환자군 에서 생존율의 통계학적 유의성은 없었다. 본 연구는 간경변의 유무, 수술 전 혈청 내 AFP 수치 및 복수의 유무는 간 절제술을 받은 환자의 장기적인 예후와 관련이 있는 반면 Ang, p53 또는 CD34는 예후적 지표가 될 수 없었다. 또한 간세포암의 파라핀 포매 조직에서 in situ hybridization이 잘 수행돤 점은 간세포암 및 여러 인체에서 발생하는 종양을 연구하는데 in situ hybridization이 유용한 기법으로 적용돨 수 있음을 보여주고 있다. Purpose: Factors affecting outcome after resection of hepatocellular carcinoma (HCC) in Korean patients are not clearly defined. This study evaluated the prognostic influence of various clinicopathologic factors in HCC. Methods: Fourteen clinicopathological factors, including expression of angiopoietin mRNA, and p53 and CD34 proteins were evaluated retrospectively in 49 patients undergoing curative resection. Survival rates were calculated by the Kaplan-Meier method. Results: By univariate analysis, survival was significantly higher in patients with Child-Pugh`s classification A, TNM stage 1 and stage 2, an absence of liver cirrhosis, a low serum α-fetoprotein level ≤200 ng/ml, and an absence of ascites. However, angiopoietin 1 (Ang1), angiopoietin 2 (Ang2), CD34 expression pattern, and p53 expression did not influence the survival rate. Conclusions: This study provides information that can be used to predict the prognosis of patients with HCC after undergoing partial hepatectomy. Although expression of Ang1 and Ang2 detected by in situ hybridization, and the immuno-histochemical detection of p53 and CD34 expression are not prognostic predictors of patients with HCC, this study shows that in situ hybridization is performed well with paraffin embedded sections in HCC.

The present study is designed to provide basic data for the future health promotion projects to be aimed at improving quality of life for the elderly people in the increasingly aging society of Korea by investigating factors related to the yangseng of old people in rural areas. The results of this study are intended to serve as fundamental for efficient approach toward health promotion projects for the elderly in rural communities. For this purpose, a survey by questionnaires was conducted to rural inhabitants from May to June 2004. The replies were analyzed from the perspective of Oriental medicine for yangseng. 1. The average points of health care appeared to be 3.24. In details by sub-areas, morality was 3.79, followed by 3.74 for activities and rest, 3.73 for sleeping, 3.29 for diet, 3.25 for mind, 2.88 for season, 2.12 for exercise and 1.95 for sexual life in sequence, showing that the yangseng of morality was scored highest while the area of sexual life were rated lowest. 2. As for the extent of health care depending on the characters of the subjects, spoused ones, married couples living alone, while the higher educated and the more leisure is utilized, the more the care is paid for yangseng. 3. Concerning the extent of yangseng depending on the general characters of the subjects, men showed more yangseng in activities and rest. The group aged 70 to 74 acquired the highest points in mind yangseng. The group with spouse featured higher concern for yangseng in the categories of morality, diet, activities and rest, sleeping and sexual life. Married couples who are living with no other family members recorded the highest points in the areas of morality, diet, sleeping and sexual life(P<0.05). 4. In terms of socioeconomic characters, the more one is educated, the more he/she is tended to take yangseng in the exercise, sleeping and sexual life. The group with occupation is inclined to take more yangseng in the activities and rest and sleeping. When people have to work for their keep, they usually showed to have highest yangseng for sleeping. People who enjoy leisure showed higher yangseng in all areas except for morality. In case man has religion, he showed more yangseng in the activities and rest, exercise and sleeping(P<0.05). 5. Those who reply they are confident with health showed higher yangseng. No significant difference was found in all areas except for sexual life in which high care is taken for yangseng, as far as one has no disease. Those who are confident with health had highest yangseng in all areas except for season yangseng(P<0.05). As seen above, extents of yangseng by the old people in the rural area are found to have difference depending on the individual and socioeconomic characters, factors which should be seriously considered in the local health promotion projects and projects for the health of the elderly. Particularly important is to launch health promotion programs and to analyze their effects to promote health care particularly in the areas of sexual life, exercise and season yangseng that turned out to be lowest by taking into account of yangseng in each sub-area.

Since old one have sought for good health and longevity, so everyone hopes that he will live long, have eternal youth and immortality. After a number of people have exerted themselves and tried to get it, they found that Dietary Cure Therapy is the most rapid and important Health-Preservation's as a basic element of health and prevention and treatment of modern diseases caused by food life. By reviewing lots of opinions and situations about the Oriental Dietary Cure Therapy, I have tried to explain the possibility of new treatments to modern diseases (noncontagious chronic disease) and to show the scientific ingestion methods through the Oriental and Occidental approaches about Dietary to find the ways of good health and longevity. 1. Food that provides a body with nutrition has been considered as an indispensable source keeping the physiological function and an immunity keeping man from a disease. Especially in the Oriental medical science, they have developed the idea that food is the nutritional basis of Jyung·Gi·Shin(精·氣·神) organizing the body, so Dietary Cure is one of Health- Promotion Theory. 2. While the Dietary Cure Therapy in modern medical science is nutrition-centered and treatment-centered method, the Oriental Dietary Cure Therapy, as a Health-Promotion Theory-centered and prevention-centered, first of all, is the most rational plan to modern diseases (noncontagious chronic diseases) which are required the prevention and improvement of daily lives. 3. The Oriental Dietary Cure Therapy that centered on the Gi(氣: energy) circulation mechanism in the body is next to be in accord with the principles and methods of Diet Restriction which is working to control senility. So it is expected to contribute to medical researches of Anti-aging and developments of health. 4. The Oriental Dietary Cure Therapy is thought to be a good prevention about chronic diseases and a method to develop the health, if we apply it to the further study scientifically, to be sure, it will be the key to solve senility and to develop the health.
