Introduction: The surgical treatment of Graves' disease has several advantage such as rapid and long lasting therapeutic effect, relatively low incidence of postoperative hypothyroidism and recurrence. Because of less frequent but serious postoperative complications, the operation have not been casually used for treatment of Graves' disease. Hypoclacemia, hoarseness and hematomas are common complications after operative treatment. However, the causative mechanisms of these complications have not been well explained. Objective: We aimed to analyze the risk factors affecting the occurance of complications in surgical treatment for Graves' disease and to evaluate what are the causative mechanisms of postoperative complications. Patients and Methods: From January 1985 to December 1998, a total of 668 surgically treated patients for Graves' disease were enrolled in this study. The incidence of postoperative complications were analyzed in relation to types of surgery, preoperaive preparation, specimen weight, bleeding amount and remnant weight. Results: Postoperative complication was developed in 108(16.2%) of 668 patients. The most common complication was transient hypocalcemia in 85 cases(12.7%). Other complications were: Hematoma in 9 cases(1.3%), transient hoarseness in 5 cases(0.7%), permanent hypocalcemia in 6 cases(0.9%), permanent hoarseness in 3 case(0.4%). The important etiologic factors affecting the occurance of complications were preoperative preparation, perioperative thyroid weight, and remnant thyroid weight. Since 1993, the incidence of complication was more decreased than that in before. Conclusion: To decrease the incidence of postoperative complications of Graves' disease, the patients should be selected carefully, sufficient preoperative preparation should be achieved, and the operation should be performed by well-experienced surgeons.

The authors have settled general modular design by analyzing related literatures, but general modular design are too massive to be applicable to all process devices. So, the common parts have to be selected, applied, and modified for the devices. We have chosen the dry pulverizing/mixing device for example. We have elected the target modules of this device such as flange, hinge, bolt, nut coupling. The remote assembling and disassembling possibilities of the selected modules have been analyzed from the viewpoints of visibility, interference, approach, weight and so on. We have presented final modular design proper to the target modules. The modular designs which have adopted the modular property been analyzed. The modular design points are comprised of common and unique points. Some points are common for several devices, such as bolt, flange and so on. Others are unique for each device, such as power transmission coupling. The experimental devices have been modified by these modular design points and the design drawings have been presented.

The problem of scheduling n jobs on a single machine is considered when the machine is subject to stochastic breakdowns. The objective is to minimize the weighted squared deviation of job completion times from a common due date. Two versions of the problem are addressed. In the first one the common due date is a given constant, whereas in the second one the common due date is a decision variable. In each case, a general form of deterministic equivalent of the stochastic scheduling problem is obtained when the counting process N(t) related to the machine uptimes is a Poisson process. It is proved that an optimal schedule must be V-shaped in terms of weighted processing time when the agreeable weight condition is satisfied. Based on the V-shape property, two dynamic programming algorithms are proposed to solve both versions of the problem.

The effect of feeding freshly-cut common grasses on growth performance of Black Bengal goats during the pre-monsoon and pre-dry season was evaluated. Four castrated goats of 5-6 months age with a mean initial body weight were 11.17 and 10.23 kg for pre-monsoon and pre-dry season respectively, were used as experimental animal. Nutrient during the pre-monsoon season contained higher nitrogen(15.6g/kg) and less DM(196.8g/kg) than the grass harvested in pre-dry season where nitrogen was 12.8 g/kg and DM was 454.9 g/kg. Intake of DM, OM, N and NDF were 73.12 g, 67.12 g, 964.68 mg and 50.14 g/kg $W^{0.75}$ respectively in pre-monsoon were higher than those in pre-dry season at p<0.01 level of significance. Higher(p<0.01) growth(35.71 g/day) rate was found in pre-monsoon season. It may concluded that grasses grown during the pre-monsoon season was higher nitrogen value and appeared to be more palatable.

Heat shock proteins are a class of molecular chaperones that can be found in nearly all organisms from Bacteria, Archaea and Eukarya domains. Heat shock proteins experience increased transcription during periods of heat induced osmotic stress and are involved in protein disaggregation and refolding as part of a cell's danger signaling cascade. Heat shock protein, Hsp20 is a small molecular chaperone that is approximately 20kDa in weight and is hypothesized to prevent aggregation and denaturation. Hsp20 can be found in several strains of Proteobacteria, which comprises the largest phyla of the Bacteria domain and also contains several medically significant bacterial strains. Genomic analyses were performed to determine a common evolutionary pattern among Hsp20 sequences in Proteobacteria. It was found that Hsp20 shared a common ancestor within and among the five subclasses of Proteobacteria. This is readily apparent from the amount of sequence similarities within and between Hsp20 protein sequences as well as phylogenetic analysis of sequences from proteobacterial and non-proteobacterial species.

It is necessary to perform the research works on the general structural designs and optimum structural designs of double hull tankers and bulk carriers due to the newly built Common Structural Rules(CSR). In this study, an optimum structural design of a mid-ship part of double hull oil tanker was carried out by using the CSR. An optimum structural design program was developed by using the Pareto optimal based multi-objective function method. The hull weight and fabrication cost obtained by the single and multi-objective function methods were compared with existing ship by the consideration of CSR and material cost which is recently increasing.

Objectives: The purpose of this study is to report weight changes and analyze adverse events in diabetic patients with Gamitaeeumjowee-Tang for weight loss. Methods: A retrospective chart review of weight change and adverse events was performed during the 10-week weight loss program using Gamitaeeumjowee-tang with low-calorie diets for diabetics(n=61). Weight and BMI changes were compared before and after the program and calculated the percentage of people who lost more than 5% of their weight, also identified whether subjects felt satiated or not. Adverse events were evaluated in terms of causality, severity and system-organ classes. Results: After 10-week weight loss program, significant weight loss (5.9±2.32kg, 7.73% reduction from baseline) and BMI reduction (2.9±0.86) were reported (n=61). Those who lost more than 5 percent of their body weight accounted for 88.5%, and also 88.5% of the participants felt full to help control their appetite. In assessing the causality of adverse events, 'Unlikely' was the most common (66%) and in severity evaluations, almost all symptoms were mild. Insomnia was the most frequently reported during the first 8 weeks, and constipation was reported the most afterwards. Conclusions: A combination of Gamitaeeumjowee-tang and low-calorie diets for 10 weeks appears to help weight reduction without serious adverse events in diabetic patients. Future well-designed prospective clinical studies testing the effectiveness and safety of this weight loss program are warranted.

Thymus속의 common thyme과 thyme의 담액수경 재배시 배양액의 이온농도를 달리하여 두 종의 생육과 품질을 비교하였다. 배양액의 이온농도는 1.2, 2.4, 4.8 그리고 $7.2mS.cm^{-1}$로 하였다. 두 종 모두 $0.5(EC=1.2\;mS.cm^{-1})$배와 1배의 낮은 이온농도 처리에서 생육이 좋았다. Common thyme과 lemon thyme의 생육은 배양액내 이온농도가 높아질수록 건물율은 증가했으나 초장, 근장과 생체중은 감소하였다. 엽록소 함량은 lemon thyme에서 더 높았으나 비타민 C의 함량과 정유함량은 common thyme에서 더 높았다. 두 종간의 주요 정유 성분 차이를 보면, common thyme의 주성분은 thymo과 carvacrol이고, lemon thyme은 geranio과 ${\alpha}-citral$로 각각 정유 성분의 50~70%를 차지하고 있다. 이들의 각 주성분의 함량은 생육이 좋았던 0.5배에서 가장 많았다. 결과적으로 수경재배시 common thyme과 lemon thyme 모두 허브 배양액 0.5배액으로 재배시 우수한 품질의 작물을 생산할 수 있었다.

보다 효과적인 색인어 추출 및 색인어 가중치 결정을 위하여 문서의 내용뿐 아니라 구조를 이용하여 색인을 추출하는 연구가 이루어지고 있는데, 대부분의 연구들이 XML 태그의 중요도가 아닌, 문맥상의 단락에 대한 중요도를 계산하는게 일반적이다. 이러한 기존 연구들은 대부분이 객관적인 실험을 통해서 중요도를 입증하기보다는 상식적인 관점에서 단순한 수치로 중요도를 결정하고 있다. 본 논문에서는 웹 문서 관리를 위한 표준으로 자리잡아가고 있는 XML 문서의 태그 정보를 이용한 자동색인을 위하여, 논문을 구성하는 주요 태그를 중요도에 따라 분류하고, 낮은 태그에서 추출된 용어 가중치를 계산하고, 그 가중치로 높은 가중치의 태그에서 추출된 용어의 가중치를 갱신해 가면서 최종 가중치를 계산하는 방법을 제안한다. 보다 객관적인 가중치 결정을 위하여 사용자가 중요하게 생각하는 태그를 실험해 보고 그에 따라 중요도를 분류하여 가중치 계산에 반영한다. 그리고 기존 태그 중요도 결정 방법을 적용하여 계산된 색인어 가중치를 이용한 검색성능과 비교함으로써 본 논문에서 제안한 방법을 적용하여 계산된 색인어 가중치의 효과를 검증한다.
