Gel consistancy의 재배환경에 따른 변이정도를 밝히기 위하여 국내 재배품종과 육성 중인 계통을 1988년부터 1992년 걸쳐 재배시기를 달리하거나 질소비료수준을 달리하여 재배, 수확한 뒤 gel consistency를 조사하였다. 1. 품종간 gel consistency의 변이정도는 상당히 켰고 공시 품종수의 85%정도가 60-100mm의 gel길이 를 보여 soft에 속하였다. 2. 자포니카 품종의 gel길이 평균치가 통일형 품종의 평균치보다 켰으며 공시한 찰벼 품종의 gel 길이는 모두 최대 값인 100mm에 가까왔다. 3. 연차변이가 작게 나타나는 품종과 크게 나타나는 품종들이 있으나 이것이 품종간 차이를 크게 뒤 바꾸지는 않았다. 4. Gel길이가 아주 길거나 아주 짧은 품종은 파종기에 따른 변이가 거의 없었으나 일부 인디카형품종은 파종기가 늦어 질수록 gel길이가 다소 짧아졌다. 5. 재배품종과 육성중인 계통의 gel consistency 는 질소시비량 따른 큰 변이를 보이지 않았으나 일부 품종은 질소시비량이 많아질수록 gel 길이가 다소 짧아졌다.

The purpose of this study was to investigate the effects of consumer's status type (status consistency and status inconsistency) on clothing expenditures. Data were obtained from Urban Household Economy Survey published by the National Statistical Office. Multiple regression analyses of variance and Scheffe tests were4 utilized in this study. The effect of the status inconsistency was categorized by three variables such as education occupation and income levels of households. The overprivileged status group which had higher levels of income than the levels of occupation of education spent most on clothing whereas the underprivileged status group which had higher levels of income than the levels of occupation of education spent least on clothing. This study showed that there were significant differences in clothing expenditures among status groups classified by levels of income and education or by levels of income and occupation. Among status group classified by levels of education and income there was a significant difference in clothing expenditures between overprivileged status group and underprivileged status group. In conclusion income has the strongest effect on the clothing expenditures. The results of study can help to understand consumer buying behavior and also give insights of marketing strategy in the apparel industry.

Background: This study was performed to reconsider the efficacy of transrectal ultrasonography (TRUS) in diagnosing prostate cancer by analyzing the results of a digital rectal examination (DRE), serum prostate-specific antigen (PSA) and a transrectal ultrasonography in patients with prostate specific antigen levels of 10 ng/ml or less. Materials and Methods: One-hundred and eighty one men with PSA levels of 10 ng/ml or less, who had a TRUS-guided tissue biopsy performed, were included in this study. The detection rate of prostate cancer was compared according to the TRUS result and the presence or absence of nodularity and the consistency of the prostate on DRE. Results: In a total 181 patients, there were 73 patients with PSA levels of 4 ng/ml or less and 4 of them had prostate cancer. Thre were 108 patients with PSA levels of 4-10 ng/ml and 18 of them were prostate cancer. TRUS was performed in 152 patients and 16 out of 58 patients diagnosed with prostate cancer, 3 out of 39 diagnosed with suspicious prostate cancer, and 2 out of 55 patients diagnosed as having no prostate cancer were found to have prostate cancer. In 40 patients, a nodule was palpated on DRE and 8 of them were found to have prostate cancer. Five out of 19 patients with a stony hard consistency, 3 of 12 with a firm to hard consisency, 12 of 129 with a firm consistency, 0 of 13 with a soft to firm consistency, and 2 of 8 with a soft consistency were prostate cancer. In the prostate cancer patients, there were 4 patients with PSA levels of 4 ng/ml or less and all these patients were diagnosed with prostate cancer or suspicious prostate cancer on TRUS but the nodule was not palpated in all patients. Two were soft and 2 were firm consistency on DRE. Conclusion: In patients with serum PSA levels of 10 ng/ml or less, TRUS is a more useful supporting method than DRE and a more active application of TRUS may lead to an early diagnosis and pertinent treatment of prostate cancer.

In this study, a part of high school science instructional materials is evaluated by Instructional Quality Profile(IQP) based on the Merrill's Component Display Theory(CDT). The CDT is based on the Gagne's assumption of different conditions of learning for different outcomes. The IQP enables the user to check both the consistency and adequacy of existing cognitive instruction. The IQP can be used to predict student performance, and also to design and develop new instructional materials. The instructional components are classified according to 5 task levels; An Use-Generalities on Newly Encountered Examples(UGeg), A Remember-Paraphrased-Generalities(RpG), A Remember-Verbatim-Generalities(RvG), A Remember-Paraphrased-Examples (Rpeg). A Remember-Verbatim-Examples (Rveg). The analyses are composed of 3 parts; Justifying the task level of objectives, Objective-test consistency, and Test-presentation consistency. The objectives, the presentations and the tests given in a teacher's guide and a textbook are analyzed. The results show that the task levels and the content levels of the objectives are not consistent with those of the tests. And the indices of the test-presentation consistency indicate the presentation problems of the instructional materials.

비동기 트리거 처리기(ATP)는 데이타베이스 트랜잭션의 수행이 완료된 후에 트리거를 처리하는 소프트웨어 시스템이다. ATP 내에서는 트리거 조건의 효율적인 검사를 위하여 차별화 네트워크(discrimination network)가 사용된다. 차별화 네트워크는 내부 상태를 메모리 노드에 저장한다. TrigerMan은 하나의 ATP로써 차별화 네트워크로써 Gator 네트워크를 사용한다. 데이타베이스의 내용 변화는 트리거맨에 토큰 형태로 전달된다. 트리거 조건의 검사는 토큰이 Gator 네트워크를 통과하면서 이루어지는데, 이때 Gator 네트워크의 메모리 노드들이 갱신된다. 토큰의 병렬처리는 시스템의 성능을 향상시키는 여러 방법 중 하나이지만 통제되지 않은 병렬처리는 잘못된 트리거 액션 수행을 유발한다. 이 논문은, 최소한의 이상 현상만을 허용하며 토큰의 병렬 처리를 가능하게 하는, 네 가지 트리거 처리 일관성 레벨을 제안한다. 우리는 각 일관성 레벨에 대하여 병렬 토큰 처리를 가능하게 하는 고유한 기술을 개발하였다. 제안된 기술은 안정된 방법이라는 사실이 공리를 통하여 증명되었으며, 이 기술은 실체화 된 (materialized) 뷰 유지 (view maintenance)에 사용될 수 있다.

The study was carried out to investigate how the refining of pulps affects the stress-strain characteristics and physical properties of paper. SwBKP and HwBKP were refined with Hollender laboratory beater to obtain three levels of freeness(500, 400 and 300 ml CSF) at the different consistencies(0.5% and 1.0%). The effects of fines were also evaluated. The stresses and strains of papers made from SwBKP and HwBKP were increased with refining. The absolute value of strain in paper made from SwBKP was higher than those of paper made from HwBKP. We also found that the presence of fines increased the stress and strain significantly in both pulp types. The refining at lower pulp consistency gave higher stress and strain properties. Most physical properties of paper were improved with refining, but the effect of refining consistency depended on the characteristics of each physical properties.

In this paper, object replication Client/server under distributed computing system is design and implementation. Today many end-users have a computer communication by using internet in the distributed system of client/server. If many users request services to a specific remote server, the server should have got a overhead for hat service processing, delayed the speed for replay, and bring a bottleneck in communication network. Therefore object replication method was proposed to solve this problems. The growth of internet works and distributed applications has increased the need for large scale replicated systems. However, existing replication protocols do not address scale and autonomy issues adequately. Further, current application protocol require consistency of different levels, and therefore should be the selection function of consistency in them, in order to have particular semantics of each level. In this paper, server overhead and bottleneck happening in remote procedure call be using server object replication. Therefore access transparency can be improved by sharing object duplicately. So it will Keep up with the consistency within the replicated objects.

This study was conducted as a part of the project to evaluate the quality of mathematics instruction in the national curriculum system. The purpose of this study is to measure the consistency between teaching goals of mathematics curriculum, contents presentation of textbooks, and testing including adequacy of each element in mathematics instruction for 8th grade. To do this, we used MIQP (instructional quality profile for Mathematics) developed basing on the instructional quality profile (IQP) in the previous research of the project. First, the quality of textbooks' content presentation for 8th grade was found that the desirable levels in number and operation area and geometric area was relatively less compared to other areas, but it was generally good. Second, it was found that the quality of mathematics testing for 8th grade was good in terms of consistency with the curriculum's teaching goals, consistency with the content presentation of textbooks, and adequacy of testing. However, regional differences in the quality of testing showed that there were some deficiencies in regions outside the metropolitan.

멀티플레이어 온라인 게임(MOG)은 수백 또는 수천명의 플레이어들을 위한 게임이며 대부분 인터넷을 이용하여 수행된다. MOG를 위한 P2P(peer-to-peer) 구조는 잠재적으로 규모조정성 증대, 비용 절감, 성능 향상 등이 가능하다. P2P 기반 게임의 기본 개념은 게임 상태를 플레이어들에게 분산 시켜서 각 플레이어가가 처리, 통신, 저장 업무를 수행하도록 하는 것이다. 객체에 대한 갱신 과정이 기본 사본에서 먼저 수행되는 기본 사본 기반 복제 기법에서도 객체들의 기본 사본은 플레이어들 간에 분산된다. 대부분의 멀티플레이어 게임은 각 객체마다 강한 일관성을 제공하기 위하여 기본 사본 모델을 사용한다. 게임은 여러 수준의 민감도를 가지며 각각의 일관성 요건에 따라 영역화될 수 있는 다양한 유형의 게임 액션들로 구성된다. 게임 내에서 각 액션의 유형마다 적절한 일관성 수준이 유지될 때 본 논문에서는 게임 개발업체가 성능과 일관성 간에 적절한 상충 관계를 선택할 수 있도록 한다. 기본 사본 모델을 갖는 P2P 게임 구조에 대한 성능 분석 결과가 기술된다.
