웹기반 교육에서 학습과정을 평가한다는 것은 개별 학습자들의 학습 활동을 평가하는 것을 의미하기 대문에 학습자의 특정 수업내용에 대한 학습 시간, 학습 패턴, 학습 참여도(의견 교환, 질문), 학습 환경 등의 정보가 요구된다. 본 연구의 목적은 웹 기반 교육에서 쟁점이 되고 있는 학습과정 평가문제를 해결하기 위해 최적의 웹 로그 마이닝을 이용하여 학습자 개인별 학습현황에 관한 정보를 얻어 이를 수행 평가에 반영하고자 함이다. 연구 내용 및 결과로는 먼저, 학습현황 분석을 위한 항목을 선정하고 웹 로그 마이닝을 위한 로그 데이터 전처리 과정을 실행하였다. 다음으로는, 위의 웹 로그 데이터를 기초로 학습자별 데이터베이스를 구축하고 질의어를 사용하여 학습현황을 분석 하였다. In Web Based Instruction, as evaluation of learning process means individual student's learning activity, it demands data on learning time, pattern, participation, environment in a specific learning contents. The purpose of this paper is to reflect analysis results of individual student's learning status in achievement evaluation using the most suitable web log mining to settle evaluation problem of learning process, an issue in web based instruction. The contents and results of this study are as following. First, conformity item for learning status analysis is determined and web log data preprocessing is executed. Second, on the basis of web log data, I construct student's database and analyze learning status using data mining techniques.

The incineration process has commonly used for wastes amount reduction and thermal treatments of pollutants as the technologies accumulated. It investigated the recycling characteristic of the fusion slag which is a last by-product which occurs from 3 facilities which are developed with Municipal waste heat decomposition gasification fusion facility of domestic. We investigated the surface characteristic of 3 melting facility slag with SEM. Therefore we found the surface is soft by cooling water. Also the surface is tough and has small air bubble by cooling air. Ca/Si ratio for alkalinity is high from the slag of the S type melting facility. The slag of T type contents contains much Fe. The melting slag has heavy metals whose contents are Cr 312.1㎎/㎏, Cd ND. Cu 105.9㎎/㎏ and Pb 3.0㎎/㎏. Each heavy metal reduction ratio is Cr 10.72%, Cd 100%, Cu 95.9%, Pb 99.9%. The amount of heavy metals contained fly ash is highly reduced through a heat decomposition fusion process re-in scattering. The Dioxin contents of fusion slag is as following: S type 2.92 pg-TEQ/g, T type 0.87 pg-TEQ/g and P type 0.21 pg-TEQ/g These are very low level comparing with the Dioxin standard 3ng-TEQ/G of Japan. Leaching rate is very low. This satisfies the recycling standard of Germany and the Dioxin Standard of Japan. Therefore we concluded that the possibility of secondary contamination may not happen.

Spastic dysarthria is a motor speech disorder produced by a damage to the direct (pyramidal) and indirect (extrapyramidal) pathways of the central nervous system. This study attempted to determine the influences of the severity of spastic dysarthria on the stability of voice. A sustained /a/, /a/ produced at the beginning of a sentence and at the end of the sentence were analyzed. The Praat 4.0.51 was used for analysis. The results showed a significant difference between the severe spastic dysarthric group and normal group matched by age and sex at the beginning and the end of the sentence. In addition, the severe group showed a significant difference between the first /a/ and the second /a/ at the end of sentence.

초등학교 5. 6 학년의 비만도에 따른 스트레스·자아존중감 조사 연구
이은주,김옥란,신영희 김천과학대학 2003 김천과학대학 논문집 Vol.29 No.-
This paper is a descriptive study that inquires about stress and self-esteem of obese children to lend assistance about understanding emotional care as weight management of children. The data collection was given by the structured questionnaire during five days, from 5th to 10th on march in 2003 at one primary school located in K-city. The subjects were 286 children in 11-12 year old children. The instruments used for this study were an Obesity-Stress Scale(Cho Yang Rae, 1997) and a self-esteem questionnaire including Self-Perception Profile(Harter, 1982). Data were analyzed with frequency, percentages, x²-test, ANOVA, Pearson correlation using the SPSS program. The results were as follows; 1. A stress of obese children was the highest among three group, which was significant of statistical data. On the other hand, self-esteem do be shown the same as the above but was not significant statistically. 2. A relation between stress and self-esteem of obese children was shown to be in inverse proportion ratio so that the higher stress was the lower self-esteem. 3. To research the differences of the stress followed by the general characteristics of children, there are meaningful differences in sex, character, factor of stress, shape of father's body and shape of mother's body. 4. To research the differences of the self-esteem followed by the general character of children, there are meaningful differences in sex, character, shape of mother's body and socioeconomic status.

Primary Angiomyolipoma of the Pelvic Region
Ok Ran Shin,Yun Seok Jung,Myung Sun Choi,Chang Hee Han,Sung Hak Kang,Yong Seok Lee 대한비뇨기종양학회 2010 대한비뇨기종양학회지 Vol.8 No.3
Angiomyolipoma (AML) is a benign tumor that is composed of adipose tissue, blood vessels and smooth muscle. The kidney is the most commonly affected organ. The incidence of AML is about 0.3-3% in the general population. AML is sometimes associated with tuberous sclerosis. Although rare, extrarenal AML has been reported to occur in other organs such as the liver, heart & mediastinum, spermatic cord, vaginal wall, and oral cavity. Primary AML in the pelvic region has very rarely been reported in the literature. Moreover, AML containing calcification is even rarer. A 61-year-old man was admitted to our hospital with a mass in the lower abdomen for 3 months. Open surgical excision was performed and the histopathological examination revealed AML. A one year postoperative follow-up showed no remarkable findings.

Abscission is an important developmental process used to shed organs such as leaves, flowers and fruits. Despite the detailed characterization of growth dynamics and hormonal balance during the early steps of fruit development, the molecular aspects remain unclear. Abscission of young fruit occurs by separation of cells in anatomically distinct regions between the pedicel and junction. Differences of gene expression between central pedicel and lateral pedicel were investigated by NGS. Partial cDNAs from 15 clones from both the central pedicel and lateral pedicel were selected for nucleotide sequence determination and homology searches, and 12 clones were subsequently selected for further analysis. In preliminary series of Real Time PCR analysis, 9 genes were confirmed as showing a higher expression level in lateral pedicel than in central pedicel. Many of these genes are expressed in a central or lateral pedicel in specific manner, and the expression profiles of the representative genes were confirmed. To clarify the mechanism of MdIAA14 transcription factor gene underlying abscission zone development, we are investigating the expression patterns between central and lateral pedicels in different apple cultivar using real-time PCR and constructing the vector for transformation into apple.

The purpose of this study was to evaluate the change of the satisfaction degrees before and after repositioning strategies between the consumers and nurses about nursing services. The subjects of this study were composed of 666 consumers and 215 nurses. Data were collected from December 2002 to August 2003. The tool used for this study was modified SERVQUAL model and the data were analyzed using SPSS/PC ver. 10.0. The result of the study were as follows: 1. The satisfaction degrees of consumers about nursing services were showed statistically significant difference in all items (before repositioning: 73.67±12.27, after 1st repositioning: 74.5±10.62, after 2nd repositioning: 79.76±11.65) The influencing factor of nursing service was marital status according to the result of multiple regression analysis. 2. There was statistically significant difference in all 5 factors which were tangibility, reliability, responsiveness, assurance, empathy (P<0.001), in the satisfaction degrees of consumers about nursing service. 3. There was statistically significant difference in 3 factors which were tangibles, assurance, empathy (P<0.000) in the nurses' satisfaction degrees about nursing service. 4. There was statistically significant difference in all 5 factors in satisfaction degrees about nursing service between the consumers and nurses (P<0.001). In conclusion, We know that this study contribute to consumers' satisfaction improvements, it was shown positive change between the consumers' and nurses' satisfaction degrees about nursing service through the performance of repositioning strategies. If continuous investigation and feed back were accomplished for the consumers' satisfaction improvements, we thought they brought us the goal of improved hospital image as well as rehospitalization, for increasing income.
