In oriental medicine Acupuncture treatment is one of the most valuable therapy. Through the acupuncture humen have been healed many diseaes with his own natural therapic power, without medicine or surgery ect. But there have not formed a clear definition on the supplement & eradication(補瀉). I recognised the difference between the original meaning of Young-su(迎隨) mentioned in $\ll$Whang-Je-Nae-Kyung(黃帝內經)$\gg$ and Young-su-Bo-Sa(迎隨補瀉) that are recently used. The results were summerized as follow; 1. In the $\ll$Whang-Je-Nae-Gyung$\gg$, when they give medical teatment, they have totally used all methods of the supplement & eradication(補瀉). Therefore as now divided into respiration, speed, rotation and close-open supplement & eradication(補瀉) have many problomes. And Young-su(迎隨) did not mean the treatement of supplement and eradication which go with or against the flowing of channel energy(經氣). Young-su(迎隨) is not a simple technique of treatment, but is the totall principle of the supplement and eradication. 2. The direction of channel energy(經氣) connected with the O-su point (五輸穴) is from extremities to the trunk of body, therefore the direction of supplement is to the trunk of body and the direction of eradication is to extermities. 3. In the case of using the treatment which go with or against the flowing of channel energy(經氣), in oder to avoid the confusion of term, it must be defined another term. 4. It is necessary that we must define the procedure of supplement & eradication, and the objective indication that ascertain whether the doctor's purposes are really obtained.

Antiphospholipid antibody is an immunoglobulin which may be of any class and which reacts with any phospholipid. For clinical use the definition of the term anti-phospholipid antibody is usually restricted to IgG and/or IgM antibody directed against the negatively charged phopholipids, cardiolipin, phosphatidyl inositol, phosphatidyl serine, or phosphatidic acid. The antigen of the serological test for syphilis is cardiolipin; negatively charged phopholipids are understood to be antigens to which lupus anticoagulants are directed. The term 'anticardiolipin' antibody syndrome, 'antiphospholipid' antibody syndrome, and 'lupus anticoagulant' syndrome are often, imprecisely, used interchangeably. We have experienced a case of recurrent spontaneous abortion with antiphospholipid antibody. So we report this case with a brief review of literatures.

21세기는 감성과 문화로 중심가치가 이동하면서 콘텐츠의 역할과 필요성이 증대되고 있다. 그중에서 만화는 원작 콘텐츠로서 무한한 가치를 지닌 것으로 평가되고 있다. 더구나 90년대 이후 .인력과 산업규모도 팽창일로에 있다. 그러나 이런 양적증가에도 불구하고 학문연구 발달이 늦고 더구나 산업계와의 유기적 협력관계가 부족한 것이 현실이다. 교재개발과 체계화가 중요하며, 만화용어의 표준화 및 사전편찬 사업들이 선행되어야 한다. 만화용어가 널리 쓰이려면 보편성이 획득되어야 하고 그러기 위해서는 시간이 필요하다. 그에 앞서 올바른 정의와 사용이 선행되어야 한다. 따라서 만화용어의 표준화 작업과 연구는 만화산업을 견인하고 학문연구의 발전을 위한 기초작업으로서 학술적 연구와 산업현장에서의 효율성 제고에 크게 이바지할 것이다.

PURPOSES : This study is aimed at development of a stochastic pavement deterioration forecasting model using National Highway Pavement Condition Index (NHPCI) to support infrastructure asset management. Using this model, the deterioration process regarding life expectancy, deterioration speed change, and reliability were estimated. METHODS : Eight years of Long-Term Pavement Performance (LTPP) data fused with traffic loads (Equivalent Single Axle Loads; ESAL) and structural capacity (Structural Number of Pavement; SNP) were used for the deterioration modeling. As an ideal stochastic model for asset management, Bayesian Markov multi-state exponential hazard model was introduced. RESULTS:The interval of NHPCI was empirically distributed from 8 to 2, and the estimation functions of individual condition indices (crack, rutting, and IRI) in conjunction with the NHPCI index were suggested. The derived deterioration curve shows that life expectancies for the preventive maintenance level was 8.34 years. The general life expectancy was 12.77 years and located in the statistical interval of 11.10-15.58 years at a 95.5% reliability level. CONCLUSIONS : This study originates and contributes to suggesting a simple way to develop a pavement deterioration model using the total condition index that considers road user satisfaction. A definition for level of service system and the corresponding life expectancies are useful for building long-term maintenance plan, especially in Life Cycle Cost Analysis (LCCA) work.

Significant portion of the total manufacturing time for a pipe fabrication process is spent on the welding following primary machining and fit-up processes. To achieve a reliable weld bead appearance, automatic seam tracking and adaptive control to fill the groove are urgently needed. For the seam tracking in welding processes, the vision sensors have been successfully applied. However, the adaptive filling control of the multi-torches system for the appropriate welded area has not been implemented in the area of SAW(submerged arc welding) by now. The term adaptive control is often used to describe recent advances in welding process control by strictly this only applies to a system which is able to cope with dynamic changes in system performance. In welding applications, the term adaptive control may not imply the conventional control theory definition but may be used in the more descriptive sense to explain the need for the process to adapt to the changing welding conditions. This paper proposed various types of methodologies for obtaining a good bead appearance based on multi-torches welding system with the vision system in SAW. The methodologies for adaptive filling control used welding current/voltage, arc voltage/welding current/wire feed speed combination and welding speed by using vision sensor. It was shown that the algorithm for welding current/voltage combination and welding speed revealed sound weld bead appearance compared with that of voltage/current combination.

Recently, robotic technologies have significantly improved, bringing considerable enhancements in many sectors; the main objective of this paper is to figure out if these innovations have also involved the building industry. To achieve this purpose, it has been considered crucial to first reshape and clarify some concepts, incorporating a much more flexible understanding of the term "robot", as well as the formulation of its future potential. Subsequently, it has been carried out an analysis of the various advanced devices that are currently available to be employed in the construction processes; the review includes a thorough classification of construction robots, divided into 18 families reflecting their purpose of use, and a dissection based on the term used to define them. The attention has been focused on the most updated and recent robots and, in their absence, on the most advanced machines prevailing. This operation has been achieved taking into account the development history of construction robots, as well as the analyses and classifications previously conducted, reconsidering them according to the just mentioned reflections. Furthermore, an in-depth exploration of the exoskeletons, as well as on a sophisticated robot recently developed by Schindler Group has been executed.

Usability is one of the most important concepts regarding software quality. It can be interpreted as the goodness associated with using the software product. This paper distinguishes the goodness of an individual using experience and the goodness of a product for using. This paper proposes a software quality view model which classifies software quality views into two broad categories of end view and means view. End view includes long-term view and short-term view which is classified further into performer's view on software activity and third party's view on software activity. Means view includes intrinsic view and contingency view. The analysis of ISO 25000 Series SQuaRE demonstrates the necessity to decompose product quality model and quality in use model into five models corresponding to the software quality views respectively. The analysis on playability shows that the universal definition of usability may be an illusion. The results provide the theoretical basis to build a comprehensive and consistent body of knowledge regarding software quality, which is consisted with the set of quality models and the theories explaining the relationships among the elements of the models.

This paper discusses the definition and concepts, approach methodologies, capable application areas in electricity business, and tentative calculation of avoided generation costs based on the Korea's official long-term generation expansion plan. The objective to evaluate avoided costs of a resource is to supply decision makers with the breakeven cost of a targeting avoided resource. For the evaluation of avoided costs of the Korea's generation system, we consider the pseudo-DSM option which has 1,000MW peak savings, load factor with 70 percent, and life-time With 25 years as the avoided resource. The DSM resource can save the fuel and capacity additions of a electric utility during its life time. The capacity and fuel savings are evaluated from the two different cashflows with and Without the DSM option, which are generated on the basis of the generation system optimization model(WASP-II), independently. The breakeven kWh costs of the DSM option over this 25-year period is projected to be 34.1[won/kWh], which is composed of generation-capacity and fuel avoided costs with 101.139[won/kW] and 17.6[won/kWh], respectively.

수학 학습에서 가장 기본적인 것 중의 하나인 용어와 기호의 뜻을 올바르게 잘 이해하는 것은 그에 연관된 학습 내용의 이해와 활용에 매우 중요하다. 곧 용어와 기호의 정의는 수학 학습을 해나가는데 중요한 시발점이 되는 것이므로 고대로부터 그에 대하여는 많은 연구가 있어 왔다. 본 연구에서는 해방 이후 우리나라의 교육과정에 제시된 용어와 기호의 변천 상황과 현행 중학교 교과서에서 사용하고 있는 용어와 기호들에 대하여 조사 분석하였는데, 변천 상황을 조사 분석한 결과는 용어의 표현 변경, 삭제, 생성에 대하여 앞으로도 보다 심도 있는 연구가 계속되어야 하겠고, 일부 용어와 기호의 보완이 필요함을 알 수이었다. 또, 현행 중학교 몇몇 교과서에서 사용하고 있는 일부 용어의 정의에 대하여는 가능한 한 학습 내용 수준에 맞는 방법으로 서술하도록 해야 하고, 누락되었거나 올바르지 못한 표현은 보완과 수정을 해야만 함을 알 수 있었다. 그리고 용어의 정의를 외국의 경우와 비교해 필요한 경우에는 조정을 하고, 용어와 기호 정의의 서술 표현에 따른 차이에서 오는 혼란을 줄이기 위해서 용어와 기호의 해설에 대한 지침을 교육과정에 게시하는 것이 바람직할 것이다.
