Background: Recently there has been evidences that serum Lp(a), an independent risk factor to atherosclerotic cardiovascular diseases, were increased in proteinuric disorders such as nephrotic syndrome and diabetic nephropathy. Methods: We intended to search of altered concentrations of Lp(a) in proteinuric disorder measuring serum Lp(a) concentrations with ELISA in 44 glomerulonephritic patients(25 nephrotic syndrome(NS), 19 non-nephrotic range proteinuric glomerulonephritis(GN), 25 diabetic nephropathy patients(DN), and 31 healthy controls(HC). Also, we compared Lp(a) concentration between glomerulonephritis patients and diabetic nephropathy patients with proteinuria of similar degree. Results: 1) There were significantly increased levels of total choesterol, triglyceride, and LDL-cholesterol in Ns compared to GN, DN, HC. 2) There were significantly increased concentrations of serum Lp(a) in NS compared to HC, but no signiicant difference in serum Lp(a) among NS, GN, and DN. 3) There was no significant difference in serum Lp(a) concentrations between NS & DN with 24 hour urine protein greater than 3.0g. 4) There was no significant difference in serum Lp(a) concentration between GN with 24 hour urine protein greater than 0.5g and less than 1.5g and DN with proteinuria of simial degree. 5) In glomerulonephritis patients, there was negative correlation between serum Lp(a) concentration and serum albumin level but correlation with 24 hour urinary protein, total cholesterol, Ldl-cholesterol, and HDL-cholesterol was not shown. In diabetic nephropathy, there was no significant correlation among serum Lp(a) concentration and all parameters including serum albumin, 24 hour urinary protein, and other lipid profiles. Conclusion: The present study confirmed that patients with nephrotic syndrome of diverse etiologies have makedly increased plasma level of Lp(a), in conjunction with other lipid abnormalities. However, this study shows no difference in Lp(a) concentrations between diabetic nephropathy and glomerulonephritis with similar degree of proteinuria.

The purpose of this study was undertaken to determine the effects of orthognathic surgery on speech. The hyposis stated herein is that functional behaviors of the dentofacial complex, such as speech production, may be adversely affected by deviations of a structural nature(especially, Class III malocclusion) . Twenty adults with Class III malocclusion(13 female and 7 male) were studied preoperative, immediate postoperative and either 6 or 12 months postoperative lateral cephalograms. They had mandibular prognathism and had undergone mandible setback operation. The position of tongue, soft palate(Uvula), hyoid bone, respiratory track width, and pharyngeal depth were assessed on lateral cephalograms with 23 cephalometric variables, ANOVA, Paired t-tests and Pearson's product-moment correlation coefficient tests were used to evalute the operative changes in all cephalometric parameters. A experienced speech and language pathologists performed narrow phonetic transcriptions of tape-recorded words and sentences produced by each of the ninth patients and the recording tapes were analyzed by phonetic computer program(Computerized Speech Lab(CSL) Model 4300BI(U.S.A.)) These judges also recorded their ratings of each patient's overall consonants, hypernasality, hyponasality, and articulation proficiency. The results obtained are as follows ; 1.There were significant changes in distance of posterior pharyngeal wall to tongue (TI-TW2, TS-TW3) after the surgery at 6 months postoperatively(each p<0.01 p<0.05) 2.The posterior tongue point(TI, TS, PPT) moved posteriorly after surgery and remained to its changed position at 6 months postoperatively(p<0.05) . The displacement of tongue was correlated with the movement of mandibular setback amount(p<0.05). The hyoid bone moved posteriorly superiorly after immediate postoperative period. There was significant changes in hyoid bone movement after immediated post-operative period(p<0.05), but returned to its original position during the follow-up period(p>0.05) 3.The soft palate was displaced posteriorly superiorly after immediated operative period and remained to its changed position at 6 months postoperatively(p<0.05) ANS-PNS-SPT angle increasing, PPU-PPPo distance narrowing was showed after surgery, and remained its appearance 6 months postoperactively (p<0.05) 4.There were significant changes in formant value and squre diagram of vowel sound after the orthognathic surgery and the follow-up period. There were significant changes in /ㅅ/sound and posterior tongue sound. 5.The posterior movement of tongue and the posteriosuperior movement of soft palate was correlated with mandibular setback amount after orthognathic surgery. On the vowel squre diagram, the author found that the place of articulation after operation moved downward, backward, upward. 6.In assessing speech abnormalities, dental occlusion should be considered as a contributing factor. The vast majority of subjects with preoperactive misarticulations eliminated or reduced their errors following orthognathic surgery. There was significant difference in speech impovement between pre- and post-operation.

권문석,김의환,조동희 한국운동역학회 2002 한국운동역학회지 Vol.12 No.2

본 연구는 6년 이상의 유도경력 소유자인 Y.대학교 유도전공자를 대상으로 맞잡기 타입과 받기신장에 따른 허벅다리걸기 동작시 3차원 영상분석법을 이용하여 운동학적 변인의 특성을 분석하는데 그 목적이 있다. 유도 맞잡기 타입과 받기신장에 따른 허벅다리걸기 동작은 비디오카메라 2대를 사용하여 촬영(30frame/sec.)하였으며, 분석을 위한 운동학적 변인들은 시간, 자세, 중심변인이며, 실험 결과에 대한 분석과 논의를 통하여 다음과 같은 결론 및 제언을 얻을 수 있었다. 허벅다리걸기 동작의 맞잡기 타입에 따른 유의한 차이는 3국면 소요시간, 걸기1단계 공격둔부각, 걸기1단계 공격무릎각, 걸기2단계 공격무릎각, 걸기2단계 지지무릎각, 걸기1단계 공격발목각, 걸기2단계 지지발목각에서 유의한 차이(p<.05)를 보였다. 종합해보면, 허벅다리걸기를 수행할 때 맞잡기와 상대신장이 허벅다리걸기 기술에 영향을 미친다는 것을 알 수 있었으며, 상대의 신장이 작을 경우 목 뒤를 잡는 타입 A가 시간이 단축(<.05)되었다. 따라서 경기 중 상대의 신장이 작다면 목 뒤를 잡는 것이 유리하다.이러한 사실들을 종합해 볼 때, 유도 경기 중 허벅다리걸기를 수행할 대 맞잡기가 많은 영향을 주었다. 또한 기술의 핵심단계인 3(걸기)국면에서도 받기신장에 의한 차가 더 크게 나타나 받기신장 역시 많은 영향을 주었다. 단계별 변인들의 변화량에 있어서는 전체적으로 모든 변인들이 변화량에서 큰 차이를 나타내지는 않았다고 할 수 있다. 따라서 맞잡기와 받기신장은 상당한 관계가 있음을 알 수 있었으며 유도 경기 중 상대에 따른 다양한 잡기와 신장을 고려한 기술이 요구된다. This study was to analyze the kinematic variables when the subjects performing Uchi-mata(inner thigh reaping throw) by Kumi-kata types((How to grasp A or B?) and two different opponent's height in Judo. Kinematic variables were temporal, posture. Data analysis was collective comparison of two-way ANOVA, t-test by type A&B and two different opponent's height. There were significant difference of Kumi-kata types(p<.05) in the time elapsed on Kake phase(KP : throwing phase) and hip, knee, ankle-angle of the attacking foot in the 1st stage of KP and knee, ankle-angle of the attacking foot and hip, knee ankle-angle of the supporting foot in the 2nd stage of KP. There were significant difference of two opponent's(p<.05) in the time elapsed on KP and hip-angle of the supporting foot in 1st stage of KP. Therefore, the interaction effect(p<.05) were in the time elapsed on KP and hip-angle of the supporting foot in the 2nd stage of KP. So, It could be suggested that Judoka hold on the part-behind neck lapel(type A) at the sleeve with the other of Judogi jacked when opponent's height was short. Because the time elapsed on KP of type B was not so fast as type A(p<.05) during performed Uchi-mata, and also the bigger hip-angle of the supporting foot in the 2nd stage of KP grew, the faster the time elapsed on KP became.

To find out the optimum fertilizer level for high yielding variety, Velox, experiment was conducted with 15 compositions of fertilizer levels at the experiment field of forage crop in Sunchon National University from Mar. 2000 to Aug. 2000. The effects of nitrogen fertilizer on plant growth were significant but increasing rate of application in potassium and phosphate fertilizers above 6 kg/a had negligible effects on plant growth. The optimum nitrogen application level of fertilizers turned out to be 16-6-6 kg/l0a of N-P2O5-K5O. Content of crude protein was highest and that of crude fiber such as NDF, ADF, cellulose and lignin were lowest at this rate of fertilizer application. Furthermore, IVDMD was high and dry matter yield were highest at the optimum raterate

The performance of the X-ray equipment's collimator system was improved by using ultrasound distance indicator and laser unit. The laser beams were coincided with radiation field. The distance between X-ray focus and film could be measured by using the ultrasound distance indicator attached collimator. According to the actual investigation in collimator, 30% of equipments were not satisfied recommendations on standard of illumination intensity, and 25% of them were not satisfied recommendations on limits of light/radiation field coincidence. Therefore by using laser beam coincided with light field the difference between light field and radiation filed could be decreased. By using the ultrasound distance indicator, the distance between focus and film could be measured easily, rapidly and correctly.

Agronomic Characters and Their Correlation Coefficient on Black Seeded Soybeans Collected in Chonnam Province

Kwon,Byung-Sun,Choi,Seong-kyu,Shin,Jeong-Sik,Shin,Dong-Youn,Kyu Hwan 한국자원식물학회 2002 Plant Resources Vol.5 No.2

In order to obtain the genetic information on the quantitative characters of black seeded soybeans, which would be needed to improve selection efficiency for breeding high yielding genotype, 45 varieties of black seeded soybeans collected in Chonnam, Korea were grown and variations of several important characters were observed. Heritability of each observed character, phenotypic and genotypic correlations among the characters and contribution of each yield component on grain yield through path coefficient analysis were estimated. Both number of pods per plant and 100-seed weight showed not only high heritability but also highly significant phenotypic and genotypic correlation with seed yield, and hence it was desirable to select plants with more number of pods per plant and higher 100-seed weight than raise seed yield of black seeded soybeans collected in Chonnam. In addition, number of pods per and 100-seed weight were proved to be the most influential variables on the viability of seed yield by path coefficient analysis. Since these showed the high heritability of number of pods per plant, selection of plants with higher 100-seed weight would be more efficient for breeding high yielding genotype.

This paper considers identical parallel machine scheduling problem. Each job has a processing time, due date, weight and family type. If a different type of job is follow by prior job, a family setup is incurred. A two phased heuristic is presented for minimizing the sum of weighted tardiness. In the first phase, using rolling horizon technique, group each job into same family and schedule each family. In the second phase, assign each job to machines using schedule obtained in the first phase. Extensive computational experiments and comparisons among other algorithms are carried out to show the efficiency of the proposed algorithm.
