The purpose of this study was to identify the controlling factors to construct tidal flat ecosystems having similar characteristics as natural ones. We transplanted the soil in a constructed tidal flat to a natural one and vice versa. Parameters monitored after these transplantations were silt content, organic matter, bacterial population and oxidation-reduction potential. Moreover, the relationship among silt content, organic matter and bacterial population was investigated by laboratory column experiment. The silt content, organic matter, bacterial population and vertical profile of oxidation-reduction potential in the soil transplanted from the constructed tidal flat to the natural one changed to similar values to those in the natural one. On the contrary, all the parameters for the soil transplanted from the natural tidal flat to the constructed one changed to similar values as those in the constructed one. The silt contents in thses two transplanted solis were in proportion to the organic carbon contents and bacterial population. Similarly, the bacterial population in laboratory column experiment increased with the increase in silt and organic matter contents. It seemed to be important to select a place to enhance accumulative of silt and/or to maintain the silt content by hydrodynamic control of seawater in order to construct a tidal flat having similar characteristics as natural one.

Anthers of cultivated Paeonia albiflora were cultured on media supplemented with various combinations of growth regulators. Although the number of anthers with emerged calluses were very few, in the sectioned anthers were found many multinucleate, 2-celled, or multicellular microspores, the one-celled multinucleate microspores being most abundant in number, and the multicellular ones the least. In 2-celled or 3-celled microspores two kinds were observed: one is ordinary one with single nucleus in each cell, and the other is multinucleate one. Majority of the 2-celled microspores was found to be of equational-division irrespective of whether they were multinucleate micropores or ordinary nonmultinucleate ones.

The role of KOH in the one-stage KOH-activation of rice straws was studied using FTIR, XPS, TGA, and DTG techniques. It was found that at the impregnation, KOH extracts to some extent the lignin component from rice straw and reacts with hydroxyl groups. On heat-treatment, the impregnated KOH facilitates intermolecular condensation reaction on one hand but retards the thermal degradation of cellulose molecules on the other hand. The oxygen-containing surface functional groups newly created by oxidation of KOH may facilitate the bulk, not controlled, consumption of carbon atoms so that the effective porosities may not be able to be developed by the one-stage activation process.

Recently, the importance of one-class classification problem is more increasing. However, most of existing algorithms have the limitation on providing the information that effects on the prediction of the target value. Motivated by this remark, in this paper, we suggest an efficient one-class classifier using hyper-rectangles (H-RTGLs) that can be produced from intervals including observations. Specifically, we generate intervals for each feature and integrate them. For generating intervals, we consider two approaches : (i) interval merging and (ii) clustering. We evaluate the performance of the suggested methods by computing classification accuracy using area under the roc curve and compare them with other one-class classification algorithms using four datasets from UCI repository. Since H-RTGLs constructed for a given data set enable classification factors to be visible, we can discern which features effect on the classification result and extract patterns that a data set originally has.

A clinical study was performed on 75 cases of the esophageal cancer and benign esophageal diseases experienced at Department of thoracic & cardiovascular surgery, School of Medicine, Keimyung University during 3 year period from 1978 to 1982. Of 75 cases of the surgical esophageal diseases, there were 35 patients of the esophageal cancer. 17 patients of benign esophageal stenosis, 10 patients of esophageal perforation, 4 patients of diverticulum. 3 patients of achalasia, 2 patients of congenital T-E fistula, one of upper esophageal web, one of esophageal foreign body, one of leiomyoma and patient of hemangioma. First, esophageal carcinoma was more frequent in men than in women by a ratio of five to one, and the peak incidence occurred in the 5th to 6th decade. Dysphagia was the most common symptom in 88.6 percent of our cases. The tumor was located mostly in the middle & the lower one third [91.4%]. The histological diagnosis was made in 35 cases. The squamous cell carcinoma was the most common [82.9%] and the rest was the adenocarcinoma in the lower one third [17.1%]. Thirty-five cases were operated and resection was feasible in the twenty-five patients [71.4%] with 2 cases of hospital mortality [5.7%]. All but two of the esophageal stenosis were caused by corrosive esophagitis and ages ranged from 7 to 70 years with average age of 32 years. Corrective operations were performed on 17 patients of esophageal stenosis of whom 12 patients had esophagocologastrostomy, 3 patients esophagogastrostomy and in non-corrosive esophageal stenosis one case and esophagoplasty and another case had release of external compression. There was one complication of stenosis of the esophageal perforation were traumatic in five cases, empyema in three cases, caustics in one case and postemetic in one case. 10 patients of the esophageal perforation underwent operation: primary closure in 5 cases, two staged colon interposition in 2, esophagogastrostomy in 1 and closed thoracotomy in 2 cases There were 2 complications of leakage of anastomosis sites in postoperative period. 4 patients of traction type of diverticulum underwent diverticulectomy & 3 patients of achalasia underwent modified Heller`s operation. 2 patients of congenital esophageal atresia had distal tracheoesophageal fistula & underwent one staged operation with the results of one death caused by pneumonia. Upper esophageal web had divulsion through the esophagoscope and foreign body in upper esophagus was removed through cervical esophagotomy. One case of leiomyoma in esophagus had esophagectomy and reconstruction with right colon. And one case of hemangioma in esophagus had esophagectomy & esophagogastrostomy.

The number of one-person households in the modern society continues to increase, and is expected to increase steadily. In addition, one-person households had the largest number of detached house dwellings, while one-person households had the advantage of free living and free time. However, one-person households have concerns such as loneliness, health problems, safety, risk, and meal solutions, while detached house have problems such as living problems, maintenance, management, safety and risk, and lead to future concerns. This study was conducted in the following ways to improve the concerns of one-person households and the problems of detached house by applying smart home service to detached house. It was integrated through the investigation of concerns and grievances of one-person households and the case of preceding research on the problems of detached house. The latest technology trends of smart home services and the technologies currently developed and marketed were identified through prior research cases and literature surveys. Based on this, the smart home service list and application measures were derived to compensate for the concerns of one-person households and problems of detached house in applying them to smart home services.
