CAD/CAM, 3차원 모델링, 가상현실, 그리고 의학 영상의 처리 속도를 높이기 위한 3차원 가속기에 대한 많은 연구들이 진행 중이다. 본 논문에서는 3차원 그래픽 처리속도를 향상하기 위하여 SIMD처리기 구조의 3차원 가속기를 제안하며, 기존의 퐁 음영법을 제안된 구조에 맞게 병렬화하고 수행함으로써 직접적인 성능분석을 시도하였다. 3차원 SIMD 처리기 구조는 PCI 지역 버스 인터페이스, 16개의 처리기, 그리고 Park's 다중접근기억장치로 구성되며, 다중접근 기억장치는 17개의 외부 메모리 모듈을 갖는다. 기존의 직렬 퐁 음영법을 SIMD 처리기 구조에 수행될 수 있도록 하나의 다면체를 여러 개의 $4\times{4}$의 정방형 다면체로 나누어서 처리하는 병렬 퐁 음영 법으로 수정하였으며, 하나의 정방형 다면체는 다중접근기억장치가 간격이 1인 블록 접근이 가능하기 때문에 17개의 처리기가 동시에 처리할 수 있다. SIMD처리기 구조에서 수행되는 병렬화된 퐁 음영법을 하드웨어 모의실험 패키지인 CADENCE사의 Verilog-XL로 모의실험을 수행한 결과 5.14배의 속도향상을 보임을 확인하였다.

의료 기술의 발달로 수명이 연장됨으로써 노년기에 어떻게 행복한 생활을 영위할 수 있는지에 대한 관심이 커지고 있다. 그런데 연령대에 따라 행복감에 영향을 미치는 변인의 유형이나 행복에 대한 변인의 영향력이 변화할 수 있기 때문에 이에 대해 실증적으로 조사하는 연구가 필요하다. 선행연구를 통해 조절초점 중 '향상초점'을 활용하는 개인이 '방어초점'을 활용하는 개인보다 대체로 행복할 가능성이 높다는 것이 발견되었다. 그러나 이와 같은 조절초점의 영향이 사람의 전생애동안 모든 연령대에 걸쳐서 유효한 것인지에 대해서는 아직 조사가 제대로 이루어지지 않았다. 따라서 본 연구에서는 거주지역과 연령대별로 성인 1250명을 무작위로 선정하여 표집을 구성하고 연령이 조절초점과 주관적 행복감 간의 관계에 대해 유의한 조절효과를 가지는지 검증하였다. 분석 결과, 향상초점과 연령은 주관적 행복감에 대해 유의한 상호작용 효과를 가진 것이 발견되었으나, 방어초점과 연령은 유의한 상호작용을 보이지 않는 것으로 나타났다. 보다 더 구체적으로 연령이 높아질수록 향상초점이 삶의 만족도와 정서균형에 미치는 정적 영향이 더 강해지는 것이 발견되었다. 본 연구결과는 노년기에 능동적으로 도전적인 목표를 설정하고, 자발적으로 동기를 부여하며 성취감을 느끼는 등 향상초점을 활용하는 것이 주관적 행복감을 경험하는 데 더 중요한 역할을 한다는 것을 시사한다. 또한 본 연구에서는 사회적 지원체제의 구축을 통해 노인의 향상초점을 활성화할 것을 제안한다.

The feasibility of the application of terahertz electromagnetic waves in the diagnosis of prostate cancer was examined. Four samples of incomplete cancerous prostatic paraffin-embedded tissues were examined using terahertz spectral imaging (TPI) system and the results obtained by comparing the absorption coefficient and refractive index of prostate tumor, normal prostate tissue and smooth muscle from one of the paraffin tissue masses examined were reported. Three hundred and sixty cases of absorption coefficients from one of the paraffin tissues examined were used as raw data to classify these three tissues using the Principal Component Analysis (PCA) and Least Squares Support Vector Machine (LS-SVM). An excellent classification with an accuracy of 92.22% in the prediction set was achieved. Using the distribution information of THz reflection signal intensity from sample surface and absorption coefficient of the sample, an attempt was made to use the TPI system to identify the boundaries of the different tissues involved (prostate tumors, normal and smooth muscles). The location of three identified regions in the terahertz images (frequency domain slice absorption coefficient imaging, 1.2 THz) were compared with those obtained from the histopathologic examination. The tissue tumor region had a distinctively visible color and could well be distinguished from other tissue regions in terahertz images. Results indicate that a THz spectroscopy imaging system can be efficiently used in conjunction with the proposed advanced computer-based mathematical analysis method to identify tumor regions in the paraffin tissue mass of prostate cancer.

The health care environment becomes more competitive every day. It has fallen to nurse managers - from vice presidents of patient care to nurse managers and their assistants - to recruit and develop a workforce that successfully meets the needs of both patients and the organization. This means employees who demonstrate advanced critical thinking skills, creative problem solving, and sound decision making skills combined with clinical skills and patient advocacy. The environment which nurse managers create and the way they relate to their workforce, are pivotal to organizational viability. Especially leadership of first -line nurse managers contributes to the success of their organizations. First-line nurse managers are deserved to be one of the most administrative supervisors through the middle stratum in a hospital organization as being a manager in the field service if assessed from the overall aspects of hospital, as being an interim managers in the nursing department as well as being a supreme supervisor in a unit in terms of an organizational structure in the hospital. Similarly, as a compete leader, the first-line nurse managers have not only a professional which is qualified to perform a role of appropriate coordination with medical staff and key personnel but also hold an important key position a being responsible for performing his or her given role. The first-line nurse manager is expected to manage human and fiscal resources in ways not required before. While an identified need for well-prepared first-line nurse manager continues to plague the profession, first-line nurse managers often have difficulty providing the leadership required. The need leadership training to function effectively in their positions. But we hardly find a useful leadership training program for first-line nurse managers, therefore the purpose of this study was to developed the leadership training program for them. The steps of leadership program development were below: 1st step, 2 studies were done before develop a leadership program. One was done to ask to first-line nurse managers what they want to learn through leadership training, the other one was to ask the staff nurses what their opinions are for their first-line nurse managers leadership. 2nd step was searching other leadership programs contents. The results of this study were below: The total amount of hours is 24. Leadership training program contents are : Future of nursing profession (210min), understanding basic factor's of leadership and leadership theories(310 min), self understanding as first- line nurse managers(320 min), basic principle and practice of interpersonal relationship(210 min), assertiveness training, conflict management (180min), and group study(210min). This is challenging time to be a leader, especially in nursing. As nurse managers look toward the new millennium, it seems as through the same struggles are ahead that are behind. So nurse managers need to embrace change with a positive attitude. They need to demonstrate risk taking and support it in their staffs. All these things are possible that after they participate the leadership training program.

Background: Breast cancer is the leading cause of cancer-related death among women in Malaysia. A diagnosis is very stressful for women, affecting all aspects of their being and quality of life. As such, there is little information on quality of life of women with breast cancer across the different ethnic groups in Malaysia. The purpose of this study was to examine the quality of life in Malay and Chinese women newly diagnosed with breast cancer in Kelantan. Materials and Methods: A descriptive study involved 58 Malays and 15 Chinese women newly diagnosed with breast cancer prior to treatment. Quality of life was measured using the Malay version of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) and its breast-specific module (QLQ-BR23). Socio-demographic and clinical data were also collected. All the data were analyzed using SPSS version 20.0. Results: Most of the women were married with at least a secondary education and were in late stages of breast cancer. The Malay women had lower incomes (p=0.046) and more children (p=0.001) when compared to the Chinese women. Generally, both the Malay and Chinese women had good functioning quality-of-life scores [mean score range: 60.3-84.8 (Malays); 65.0-91.1 (Chinese)] and global quality of life [mean score 60.3, SD 22.2 (Malays); mean score 65.0, SD 26.6 (Chinese)]. The Malay women experienced more symptoms such as nausea and vomiting (p=0.002), dyspnoea (p=0.004), constipation (p<0.001) and breast-specific symptoms (p=0.041) when compared to the Chinese. Conclusions: Quality of life was satisfactory in both Malays and Chinese women newly diagnosed with breast cancer in Kelantan. However, Malay women had a lower quality of life due to high general as well as breast-specific symptoms. This study finding underlined the importance of measuring quality of life in the newly diagnosed breast cancer patient, as it will provide a broader picture on how a cancer diagnosis impacts multi-ethnic patients. Once health care professionals understand this, they might then be able to determine how to best support and improve the quality of life of these women during the difficult times of their disease and on-going cancer treatments.

As a result of studing on the "shashen(沙蔘)", we could reach conclusions as follows. 1. Shashen is the root of "lunyeshashen(潤葉沙蔘)", "kuoyeshashen(闊葉沙蔘)", and its same generic plants that belong to Companulaceae. In china people has used twenty-four species as a shashen together with other generic plants, in korea sixteen species as a shashen. 2. At first, in the "Shen Nong's Herbal(神農本草經)" it was recorded and then in the "Benchingfengyuan(本經逢原)" divided into "nanshashen(南沙蔘)" and "beishashen(北沙蔘)". Recently, nanshashen called shashen belongs to Companulaceae and have strong efficacies of clearing away heat from lung, resolving phlegm, beishashen belongs to Umbelliferae and have strong efficacies of nourishing stomach, nourishing yin. 3. Shashen is the root of Adenophora stricta Miq., and yangru(羊乳) is that of Codonopsis lauceolata Bentham et Hooker, jini is that of Adenophora remotiflora (SIEBOLD et ZUCCARINI.) MIQUEL. From a efficacious point of view, it is the characteristics that shashen have efficacies of nourishing yin and clearing away heat from lung, supplementing stomach and promoting production of body fluid, resolving phlegm and relieving cough, eliminating pus and abscess, expelling wind and pruritus, jini have those of clearing away heat and toxic material, resolving phlegm and yanru have those of nourishing yin and moistening lung, resolving phlegm and eliminating pus, clearing away heat and toxic material, stimulating milk secretion. 4. After being recorded as "zhimu(知母)" in Shen Nong's Herbal, the alias of shashen was recorded as kuxin(苦心), shimei(識美), huxu(虎須), baishen(白參), zhiqu(志取), wenhu(文虎), baolishen(保利參), paoshen(泡參), jibantui(鷄半腿), yangponai(羊婆妨) and so on. Moreover shashen was named after its characteristics of that it grows well in the sandy soil and as a wushen(五參) with a renshen(人蔘) its form is different from that of wushen but their chief virtues are alike. 5. In the numerous medical books, xinyeshashen(杏葉沙蔘) regarded as nanshashen. It was called as the alias of jini, so I thouhgt that it was wrong xinyeshashen to be regarded as nanshashen. 6. It was used shashen for renshen, renshen was used to treat lung-cold syndrome by its efficacy of tonifying yang and shashen lung-heat syndrome by its efficacy of nourishing yin, the reasons of that because shashen had amount of sap, its properies and flavours of herbs are light and clean. 7. The constituents of shashen were essential oil, starch, shashen-saponin, furocoumarin, xanthotoxin(ammoidin), inulin, sugar, mucus and have efficacies of resolving phlegm, promoting production of body fluid, immunomodulational and antibiotic efficacies. above results indicated that the origin of shashen and substitutional plants was various. Their efficacies are somewhat alike, but there were characteristic efficacies each other. Nowadays they are used together with, so we should know the characteristic efficacies of them and then we using them clinically, more deep discrimination and experimental support shoud be accomplished.

The purpose of this study was to investigate the influence of the factors such as self-esteem, social supports, socio-economic status of parents, degree of disability in child, stress coping, religion, and sports.exercise on the qualities of lives in mothers with disabled children. Data were collect from 45 institutions(schools from kindergarten to senior-high, special education institutes, and social welfare institutions) by self-report questionnaire, and the subjects of the study were 386 mothers in Seoul whose children were attending the schools or institutions. Findings according to socio-demographic variables are as follows: 1. Mothers with disabled children in this study thought their quality of life as average degree. 2. The younger the mothers and children, the higher the quality of life was. 3. The higher the educational level and monthly income, the higher the quality of life was. 4. There was no statistically significant difference between the existence and nonexistence of spouse, and between the existence and nonexistence of religion as well. Findings analyzed by multiple regression are as follows: 1. Among 7 independent variables 'self-esteem'(${\beta}$=.49, p<.001), 'social supports'(${\beta}$=.15, p<.01), and 'socio-economic status'(${\beta}$=.11, p<.05) were found to be statistically significant in quality of life in mothers, while the rests were found not significant. 2. 'Self-esteem' was found to be the most influencing variable, meaning that the psychological factor such as self-esteem is more important than environmental factors in qualities of lives in mothers. 3. The total amount of explanation of the model was Adjusted R square=.301, so that it can be said about 30% can be explained among total variance of the qualities of lives in mothers with disabled children. Conclusions and recommendations based on the results above are: First, it is strongly recommended to conduct programs promoting self-esteem in mothers with disabled children, and to include 'self-esteem' hereafter in the studies related to qualities of lives in mothers with disabled children. Second, comprehensive and practical countermeasures should to be formulated to back up expenses for education and medical care, purchasing relative tools and equipments, plus helping to find jobs.

Translational research (TR) as high quality research can accelerate collaboration strongly between biotechnology-based researchers and clinical-research experts for overcoming diseases. TR facilitates basic science translated to clinical efficacy and effectiveness from bench (basic science) to bedside (clinical practice) for the enhancement of human health. Disease-oriented TR programs were defined as unilateral, bilateral and multilateral TR in this patent performance analysis. Patent performance was measured in a R&D project on Health and Medical Technology to enhance the productivity of R&D investment on disease-oriented TR in Health Technology (HT). Patent Map (PM) analysis and Bibliometrics were conducted to collect information for the assessment of research patents of TR programs. Futhermore, PIAS (Patent Information Analysis System) and Thinklear programs were applied for quantitative and qualitative analysis successfully. These indicate that multi-dimensional analysis of patent performance for disease-oriented TR could promote the connection of R&D-IP (Research and Development-Intellectural Property) and R&BD (Research and Business Development) supporting system significantly.
