최근의 대부분의 정보시스템은 웹 기반 정보시스템이며 이의 개발과 유지보수시에 “웹 위기” 현상이 발생하고 있다 이를 해결하기 위해, 웹 엔지니어링 기술 중 웹 기반 비즈니스 프로세스로의 리엔지니어링 기술이 필요하다. 본 논문에서는 웹 기반 정보시스템으로의 이주와 웹 기반 비즈니스 프로세스 모형화를 위한, BPN(Business Process Net) 모형과 이를 이용한 리엔지니어링 휴리스틱스를 적용 예와 함께 제시한다. BPN모형은 베타분포형 확률 패트리넷이며 수행가능형 Activity diagram이라 할 수 있다. BPN을 모형화 할 때, Use Case 분석을 이용하며 비즈니스 프로세스의 수행시간 및 비용적 불확실성은 베타분포를 이용하고 있다. BPN 모형은 XML 기반의 비즈니스 프로세스의 명세언어를 위한 공통 명세모형으로 이용될 수 있으며, 제시한 리엔지니어링 방법 및 지침은 웹 기반 정보시스템의 분석 및 설계단계에서 적용할 수 있다. A web-based information system, that is a dominant type of information systems, suffers from the “web crisis” in development and maintenance of the system. To cope with the problem, a technology of reengineering to web-based business process, which is one of web engineering, is strongly needed. In this paper, we propose a BPN(Business Process Net) model and reengineering guides along with an application example, which are used for modeling web-based business processes and migrating to web-based information system. BPN model is a type of not only a Beta-distributed stochastics Petri net, but also an executable Activity diagram. BPN is modeled by using the Use Case analysis method and the Beta-distribution. The later is used for the purpose of modeling the uncertainty of execution time and cost of a business process. BPN model and reengineering heuristics might be used as a formal common model for business process specification languages, and analysis and design method for Web-based Information system, respectively.

Osteoporosis is the most common metabolic disease of the bone, and constitutes one of the most important major pubulic health problems world wide. Therefore, in order to be helped early diagnosis, treatment and prevention of osteoporosis, measurement of Bone Mineral Density (BMD) is to be needed. Authors has analysed Bone Mineral Density (BMD) of 480 normal adults who visited woo suk unoversity Oriental Meclical Center from April 1998 to July 1998. The aims of this study is to investigate correlation between Bone Mineral Density (BMD) and age distribution, to examine the correlation between Bone Mineral Density (BMD) and Obesity. The results were as follows. 1. In distribution of age, the peak bone density of lumbar spine was noted around 30 years, and the peak bone density of the femoral neck was noted around 20 years. The age related loss of bone density follows soon after peak density. And the signifficant difference was revealed between lumbar spine and femoral neck bone density (p<0.001) 2. In distribution of sex, the bone density in male was signifficantly higher than in female (p<0.001). 3. In the correlation between Bone Mineral Density (BMD) and Obesity, Bone Mineral Density (BMD) in obese group was signifficantly higher than in non-obese group. Especially, in female from 50 up to 69 years, BMD had a positive correlation with Body mass index(BMI).

The purpose of this study was to determine the effects of aqua-acupuncture of Laennec N HO (Hominis placenta Cervi pontotrichum cornu Carthami semen). on trabecular area and physiological change in ovariectomized osteoporotic rats. This experiment was performed to .investigate an antiosteoporosis. effects of Laennec N HO(Hominis placenta Cervi pontotrichum cornu Carthmi semen) aqua-acupuncture on the osteoporosis induced by both ovariectomy in Rats. So rats were divided into Sham group and OVX group. OVX groups were divided into control group, Exp. I group, Exp II group and Exp III group). The Ratios of trabecular area seen in ephiphysis and diaphysis of tibia and lumbar vertebral body and physiological change were as follows. 1. In the proximal ephiphysis of tibia, Exp I II III groups were significantly increased compared to that in control group (p<0.05). 2. In the diaphysis of tibia, Exp III group were significantly increased compared to that in control group (p<0.05). 3. In the first lumbar vertebral body, Exp II group were significantly increased compared to that in control group. 4. In the cortical thickness index of tibia, Exp III III groups were significantly increased compared to that in control group. 5. Osteoca1cin was increased in the Exp II group than those of other Experiment groups and control group, and Phosphorus was decreased in the Exp I II group than that in control group, But a significant difference was not seen. GOT, GPT and Alkaline phosphatase were decreased in all Experiment groups than that in control group. But a significant difference was not seen. From the above results, it might be suggested that aqua-acupuncture Laennec N HO(Hominis placenta Cervi pontotrichum cornu Carthami semen) prevented the increase in bone turnover and the decrese in bone mass induced by OVX in rats.

광합성 색소의 HPLC 분석을 위한 여과지 분쇄 효과 평가

장수진,박미옥,Jang, Su Jin,Park, Mi Ok 한국해양학회 2015 바다 Vol.20 No.2

High-Performance Liquid Chromatography (HPLC) 분석방법은 식물플랑크톤의 생물량 및 일차생산력을 추정하기 위한 지시자로서 chlorophyll a 농도를 측정하고 carotenoids의 종류를 파악해 종조성을 확인하기 위해 널리 이용되고 있다. 그러나 대량시료의 분석에 요구되는 시료 전처리 과정 중 여과지 분쇄는 상당한 시간과 숙련이 요구된다. 본 연구에서는 엽록소 및 carotenoids의 정량분석에 대한 여과지 분쇄의 영향을 파악하고자 동해 남서부 해역의 시료를 이용해 여과지 분쇄 전후의 광합성 색소 농도를 비교 평가했다. HPLC 분석에서 여과지 분쇄 생략 시 Chl a의 경우 평균 45% 과소평가되었다. 또한 pico, nano 크기 식물플랑크톤의 지표색소인 Zeaxanthin, 19'-butanoyloxyfucoxanthin, 19'-hexanoyloxyfucoxanthin는 최대 77~85% 과소평가되었다. 크기가 작은 식물플랑크톤의 경우 여과지 분쇄가 생략될 경우 불완전한 추출로 지표색소의 농도가 실제보다 저평가될 가능성이 크다는 것을 확인하였다. 따라서 HPLC 분석에서 여과지 분쇄 생략 시 Chl a 뿐 아니라 carotenoids 또한 과소평가 되므로 모든 경우에서 여과지 분쇄 과정이 반드시 필요하다고 판단된다. High-Performance Liquid Chromatography (HPLC) is a widely used method for measuring the concentration of chlorophyll a as an indicator for estimating phytoplankton biomass and primary production and also for identifying carotenoids to determine phytoplankton composition. However, tissue grinding procedure requires a lot of time and experience in the analysis of multiple sample. Accordingly, we measured the concentrations of photosynthetic pigments before and after the grinding, in order to understand the grinding effects on the quantitative analysis of chlorophylls and carotenoids using samples from southwestern East Sea. When tissue grinding procedure was omitted, we found that Chl a concentrations were underestimated up to 45% in average. Also, concentrations of Zeaxanthin, 19'-butanoyloxyfucoxanthin, 19'-hexanoyloxyfucoxanthin, biomarkers of pico and nano-size phytoplankton, were underestimated up to maximum 77~85% without grinding. We found that the smaller the phytoplankton, the bigger underestimation of their biomarker pigments concentration is likely to happen due to the incomplete extraction. Thus, tissue grinding procedure should be included for HPLC analysis in all cases, to prevent the underestimation of not only Chl a but also carotenoids pigments.

장수진(SuJin Jang),고병현(ByengHyen Ko),서인영(InYoung Suh) 전력전자학회 2010 전력전자학술대회 논문집 Vol.2010 No.11

본 논문은 당사에서 개발한 250㎾ 태양광 인버터의 실증운전에 관한 내용이다. R&D 단계에서의 제품 시험은 실 사용 환경에서 발생하는 이상 동작 원인을 검증할 수 없다. 또한, 주위환경(온도, 일사량 등)에 따라 발전량이 수시로 변동하므로 고품질의 전력을 생산하기 어렵다. 따라서, 태양광 인버터와 같이 주위 환경에 영향을 많이 받는 제품은 제품 출시 전 실제사용 환경을 고려한 대책 설계/제어가 필수이다. 당사에서는 개발 제품의 신뢰성을 확인하고자 태양광 인버터를 실 사용 환경에 적용하여 장기 연속 운전하고 있으며, 실증운전을 통해 수집된 결과를 비교/분석하여 제품 개발에 활용하고 있다.

The Korean auxiliary verbs have many function including helping main verbs in the predicate as well as expressing aspect, which makes it difficult for non-native learners of Korean who have different linguistic intuitions to understand their usage. The purpose of this paper is to explore a learning method that will enable learners of Korean to acquire the usage of Korean auxiliary verbs systematically and use themin real-life situations. The learning method for Korean auxiliary verbs presented in this study is based of a list of selected and rank-ordered Korean auxiliary verbs to be taught and learned according to the learner`s level and stage of learning. The order of the auxiliary verbs to be learned at each level can be determined by the following methods. Fist, the frequency of actual use of the words in the selected auxiliary verb list and the frequency of the exclusive use of the words as auxiliary verbs are assessed and ranked. Second, the polysemous meanings of the words in the auxiliary verb list are examined and the rankings are determined based on the frequency of each monosemous meaning and Finally, the rank order of the words in the list to be learned is determined by combining the results of the two above. The learning method that presents the learners with the auxiliary verbs in the rank-ordered list according to their level and stage of learning is expected to be and effective resource for learners of Korean in their learning of auxiliary verbs.
