An alternative interpretation of the completeness requirements for the higher order elements is presented. Apart from the familiar condition, $\sum_iN_i=1$, some additional conditions to be satisfied by the shape functions of higher order elements are identified. Elements with their geometry in the natural form, i.e., without any geometrical distortion, satisfy most of these additional conditions inherently. However, the geometrically distorted elements satisfy only fewer conditions. The practical implications of the satisfaction or non-satisfaction of these additional conditions are investigated with respect to a 3-node bar element, and 8- and 9-node quadrilateral elements. The results suggest that non-satisfaction of these additional conditions results in poorer performance of the element when the element is geometrically distorted. Based on the new interpretation of completeness requirements, a 3-node element and an 8-node rectangular element that are insensitive to mid-node distortion under a quadratic displacement field have been developed.

대부분의 빈발 패턴은 패턴이 트랜잭션 데이터베이스에 나타나는 support를 패턴 interestingness의 핵심 척도로 다루어 왔으나 패턴의 횟수는 패턴의 completeness가 가지는 정보를 최대치로 가정하고 있다. 그러나 실제적으로는 임의의 패턴 X의 completeness는 트랜잭션에서 서로 다르게 나타나기 마련이다. 따라서 패턴이 가지는 정보의 손실을 줄이기 위해서는 가중치에 의한 support와 completeness에 의한 유용한 패턴 마이닝을 고려하여야 한다. 즉, 높은 completeness율을 갖는 패턴은 더 높은 recall로 이어질 수 있고 높은 빈도수를 갖는 패턴은 보다 높은 정밀도로 이어진다. 본 논문에서는 동적인 항목들의 가중치에 따른 적응된 support와 completeness를 고려하는 WSCFPM 패턴 마이닝 알고리즘을 제안한다. 제안한 방법은 모노톤 또는 반 모노톤 속성이 가중치에 의한 support와 completeness에 영향을 미치지 않기 때문에 탐색과정을 줄일 수 있다. 실험결과를 통하여 제안된 알고리즘이 효과적이며 확장성이 좋은 것임을 보인다.

The classical 8-node isoparametric serendipity element uses parametric shape functions for both test and trial functions. Although this element performs well in general, it yields poor results under severe mesh distortions. The distortion sensitivity is caused by the lack of continuity and/or completeness of shape functions used for test and trial functions. A recent element using parametric and metric shape functions for constructing the test and trial functions exhibits distortion immunity. This paper discusses the choice of parametric or metric shape functions as the basis for test and/or trial functions, satisfaction of continuity and completeness requirements, and their connection to distortion sensitivity. Also, the performances of four types of elements, viz., parametric, metric, parametric-metric, and metric-parametric, are compared for distorted meshes, and their merits and demerits are discussed.

Objectives: This study is conducted to identify the cancer incidence in Gwangju during the 5-year period from 1998 to 2002 and to assess the completeness and validity of the cancer registry data during this time period. Methods: All cases that had a diagnosis of invasive cancer (ICD-10 sites C00-C97) during the study period were retrieved from the records of the Gwangju Cancer Registry (GCR), which theoretically includes all the cancer cases in Gwangju. All the cases during the study period were analyzed by gender, age group and cancer sites. The completeness (mortality/incidence ratio and age-specific incidence curve) and validity (histologic verification, primary site unknown, age unknown and death certificate only) of the cancer registry in Gwangju were analyzed by gender, age group and cancer sites for the 5-year period. Results: The overall cancer incidence was higher in the males than in the females (age-standardized incidence rates (ASR) 299.8 and 172.4 per 100,000, respectively). In males, the most common cancer was stomach (ASR: 65.8), followed by liver (ASR: 50.5), bronchus and lung (ASR: 50.5), colo-rectum (ASR: 26.7), oesophagus (ASR: 10.6), and bladder (ASR: 10.3) in descending order. In females, the most common cancer was stomach (ASR: 26.8), followed by thyroid (ASR: 20.7), breast (ASR: 20.4), cervix uteri (ASR: 14.3), bronchus and lung (ASR: 13.0), liver (ASR: 10.7) and colo-rectum (ASR: 17.2) in descending order. The overall quality (completeness and validity) of the cancer registry was at the in 'good' level. Conclusions: These results will be useful in the overall context of planning and evaluating of cancer control activities in Gwangju.

In this work, an automatic software verification method for Nuclear Power Plant (NPP) protection system is developed. This method utilizes Colored Petri Net (CPN) for system modeling and Prototype Verification System (PVS) for mathematical verification. In order to help flow-through from modeling by CPN to mathematical proof by PVS, an information extractor from CPN models has been developed in this work. In order to convert the extracted information to the PVS specification language, a translator also has been developed. ML that is a higher-order functional language programs the information extractor and translator. This combined method has been applied to a protection system function of Wolsong NPP SDS2(Steam Generator Low Level Trip). As a result of this application, we could prove completeness and consistency of the requirement logically. Through this work, in short, an axiom or lemma based-analysis method for CPN models is newly suggested in order to complement CPN analysis methods and a guideline for the use of formal methods is proposed in order to apply them to NPP Software Verification and Validation.

This study is a review on the relationship between furniture purchasers and producers in the Joseon period. Understanding the relationships in our traditional spirit and the Joseon furniture that reflects a aesthetic sense is a meaningful work. Joseon was to build an ideal country which put emphasis on the order and harmony through Theory of 'Yeak' as the confucianism nation. Human aesthetics, which emphasis on the spiritual value by confirmity to nature and forcus on the relaxed, deficient personality rather than completeness was established as the central formative consciousness of the Joseon Dynasty. The nature of things in the confucian scholar prior to the representations of things is expressed in the form of master craftsman's skill and soul. Formative consciousness of the confucian scholar is to realize ideals by communciation and interchange with master craftsman's soul in the form of the Joseon furniture. The beauty of restraint and brevity in the Joseon Dynasty furniture includes meanings and procedures of art work. It implies an orderer's purpose of production and a producer's products. Understanding the spirit of times in the production becomes the cornerstone capable of getting closer to the furniture ultimate proper function. These problems have a very close relationship with the problems of modern people's commnuication. We expect an even higher growth of the furniture by achieving more improved communication based on the consumer's great insight and the producer's passion.

I present a model to explain the mass segregation and shallow mass functions observed in the central parts of starburst stellar clusters. The model assumes that the initial pre-stellar cores mass function resulting from the turbulent fragmentation of the proto-cluster cloud is significantly altered by the cores coalescence before they collapse to form stars. With appropriate, yet realistic parameters, this model based on the competition between cores coalescence and collapse reproduces the mass spectra of the well studied Arches cluster. Namely, the slopes at the intermediate and high mass ends, as well as the peculiar bump observed at $6M_{\bigodot}$. This coalescence-collapse process occurs on a short timescale of the order of the free fall time of the proto-cluster cloud (i.e., a few $10^4$ years), suggesting that mass segregation in Arches and similar clusters is primordial. The best fitting model implies the total mass of the Arches cluster is $1.45{\times}10^5M_{\bigodot}$, which is slightly higher than the often quoted, but completeness affected, observational value of a few $10^4M_{\bigodot}$. The model implies a star formation efficiency of ${\sim}30$ percent which implies that the Arches cluster is likely to a gravitationally bound system.

This study is to analyze the kinematic variables of inward $1{\frac{1}{2}}$ somersault in platform diver. For the manner, 3 people form the national diving team in the year 2000were chosen as the subjects and two S-VHS video cameras set in 60frames/sec were used for recording their motions. Coordinated raw positions data through digitizing are smoothing by butter-worth's low-pass filterin method at a cut off frequency 6.0Hz. and the direct linear transformation(DLT) method was employed to obtain 3-D position coordinates. The conclusions were as follows. However, horizontal distance which is the change of the COG, form the point of the jump to the point of Event 3 where the player is out of the board range completely, Subject B showed 105.1cm and 71.1cm of the vertical distance which are shorter horizontal distance and higher vertical distance, thus, took a great advantage of the position to prepare for the entry. Therefore, if a player takes higher position by speeding up the vertical velocity at the moment of the jumping off the board, and stays in the air longer, the player can have more time to show his skill. Because of the use of the characteristics of the inward somersault, keeping the safe distance form the board is important but in order to higher the completeness, it is ideal to keep the horizontal distance little over 100cm. Also, the angles of shoulder and elbow from Event 1 to 4, depending on swing of the arms, motions in the air, getting ready for the entry, showed some difference individual by individual, according to the velocity of the thigh and shank showed much difference while getting ready and take-off, and it's because of the individual's different bending and straightening for horizontal and vertical distance.
