Penetrating morphologies at the growth front of abnormally-growing Goss grains in Fe–3%Si steel was examined in view ofthe possibility that they are the two-dimensional section of the solid-state wetting (SSW) along the triple junction line. Toobtain the statistically meaningful data, 102 penetrated grain and 204 penetrating abnormally-growing Goss grain morphologieswere examined. The misorientation angles of penetrating and penetrated grains were measured by electron backscattereddiffraction. Among the 102 examined penetrated grain boundaries, none has low misorientation angles less than 15°,whereas 17.2% of the 204 penetrating grain boundaries have low misorientation angles, and 23.5% of them have coincidencesite lattice boundaries. Besides, boundary energies of penetrating Goss grains, which were estimated from misorientationangles of the three grains in the penetrating morphology, satisfied the energetic condition for SSW along the triple junctionline. These results imply that the abnormal grain growth of Goss grains in Fe–3%Si steel occurs by the mechanism of subboundaryenhanced SSW.

Prolapse of the fallopian tube into the vaginal vault after hysterectomy is a rare complication. Since most of cases may resolve before detection or remain undiagnosed, the exact incidence is still unknown. Though most common sign of tubal prolapse is tender friable tissue in vaginal cuff, with the simptoms of lower abdominal pain, dysparenunia, vaginal discharge, or postcoital spotting. The definitive diagnosis should be confirmed histologically Recently, we experienced a case of fallopian tube prolapse after abdominal hysterectomy in a 41-year-old woman and report with a brief review of the literature.

This study was performed to investigate the pollution-free papermaking characteristics from paper mulberry by sulfomethylation pulping. Bast fibers were pulped by sulfomethylated cooking liquor and by alkali and alkali-peroxied processes for the comparison. Sulfomethylated pulping resulted in the superior pulp with high yield and better quality compared to those of alkali and alkali- peroxide pulps. Since the pulp was so bright, there was almost no need additional bleaching. Polluttant loads of sulfomethylated pulping effluent were very low in terms of pH, turbidity and color compared to those of alkali. Pollution-free effluents was accomplished by simple filtering treatment with pine bark, charred rice hull and sawdust compost. Pine bark was the most effective in reduction rate of pollutants. Key words : Korean traditional paper, Paper mulberry, Alkali-Peroxide, Sulfomethylated pulping, Effluent.

To conditioning sludge to occure in the course of food processing industry, after culturing Rhoodotorula glutinis, dosing a certain amount of culture solution into the sludge and measured the variation of total suspended solids and then, in the aerobic and anaerobic conditions after manage sludge, examining the result of measured specific resitance, the coefficient of cmopressibility to know the dewateability. Arrangements of this result are as follows : 1) As the result of total suspended solids concentration by change of aeration time and the amount of Rhodotorula glutinis dose, optimal dose was Rhodotorula glutinis 10㎖ by 20㎖ sludge. The very suitable aeration time was 4-5days. 2) After dosing biological conditioner(Rhodotorula glutinis) 60㎖ by 11 sludge in aerobic condition, aeration for five days. The results of specific resistance, the coefficient of compressibility were 22.71×10^(5)m/㎏ 1.6, respectively. 3) In the cases of using Rhodotoruls glutinis for biological conditioner, using polymer for chemical conditioner. This results are as follows : Biological conditioner ; the moisture content of sludge cake 77.7% Chemical conditioner ; the moisture content of sludge cake 70.3% But, I author propose that biological conditioner is more useful than chemicals in the total operating and maintenance cost.

A carcinoid tumor of the stomach is uncommon, has no clinical symptoms, and is regarded as a benign. It is also incidentally found in most cases. 48-year-old woman with gastric carcinoid tumor was admitted. She had suffered from a anorexia and a dry mouth for 4-months. A gastroscopy revealed a polypoid mass on the greater curvature of the mid-body of the stomach which was subsequently thought to be an adenocarcinoma. An endoscopic mucosectomy revealed however, that it was a carcinoid tumor. A case of carcinoid tumor of the stomach is here by presented with a brief literature review.

This paper describes the path planning method in an unknown environment for an autonomous mobile robot equipped with CCD(Charge-Coupled Device) camera. The mobile robot moves along the guideline. The CCD camera is used for the detection of the existence of a guideline. The wavelet transform is used to find the edge of guideline. It is possible for us to do image processing more easily and rapidly by using wavelet transform. We make a fuzzy control rule using image data as an input then determined the position and the navigation of the mobile robot. The center value of guideline is the input of fuzzy logic controller and the steering angle of the mobile robot is the fuzzy controller output. Some actual experiments show that the mobile robot effectively moves to target position by means of the applied fuzzy control.

This study was carried out to investigate the papermaking characteristics for New Hanji (Korean Paper) products from paper mulberries. So far the bast fibers of paper mulberry species have been used as raw materials for Hanji. But, in this study, bast fibers, woody parts and whole woods are attempting for being utilize as new raw materials for special Hanji. Anatomical and chemical properties of 3 paper mulberry species and their pulping characteristics were discussed.

For the investigation of the economics of mushroom(Lentinus erodes) cultivation in the oak bed- log, the items of production costs were examined. The results are as follows ; 1. Among the items of cultivation costs in the first year, the material bed-log cost(62.4% ) was the highest, then the labor cost was. 2. The labor costs for management(27.6-28.1%), bed-log handling(26.8-27.9% ) and mushroom harvesting(26.2-27.9%) were higher than the others from the 2nd year to the sixth year. 3. The gross income and the cultivation cost per one bed- log were 15,672 won and 3,170 won for six years. 4. For six years, the total net income was 12,500 won and the annual income was 2,080 won per one bed- log.

As central cities of the provinces north of Gyongsang, Mungkyeong, Andong, Yeongju have to set up a strategic plan of attracting more international and domestic tourists for development of central districts broadly. In particular, Mungyeong city puts spurs to develop after foundation of Mungyeong Tourism and Leisure Town Inc., which the Ministry of Commerce, Industry and Energy, Kangwon land, Mungyeong city joint-found on April 2003. All citizens put their effort on developing the Mungyeong Tourism and Leisure Town Inc., which is invested of national (government) and private expenditure about 11hundred million won. There are several alternative plans that enabled balance-development of promoting tourism locality. However, secure of investment capital is more important in tourist attractions-article connection. The stable secure of financial support for tourism development is primarily based on local economic activity. Unfortunately, almost all Korea local authorities foundations have radical limitation of promoting to tourism development project, this is mainly due to weak economic situation with fragility in local financial. Therefore, it is significant to get the central government and a megalopolis governments intervention regarding tourism development project. At present, the tendency is toward increasing of participating in private sectors and coming under private management in all kinds of development project. In addition, there found some limitation of promoting relative management only in the public organization, thus it is important to induce active private departments participation. Basically, it is essential to find out key factors of overcoming the difficulties on attracting private sectors investment and their participation. At the same time, there need to seek solution of the difficulties and execute offering the incentives hence attract private investment. According to the results from confidence-analysis and factor-analysis, the infrastructure and the expansion of social indirect capital are urgent through active supporting of a central government, megalopolis government and connection of tourism system. Moreover, it is suggested that there need to promote establishing of effective information-system, and correctness in tourist information, which affect in decision of a tourism policy. Finally, it is vital to promote development of tourist attractions-article connection.
