The Korean government introduced a private-initiative park project to prevent further environmental damage caused by the abolition of parks. The private-initiative park project is expected to affect the connectivity of the green space system by creating a part of the park site as a non-park facility. The purpose of this study is to analyze the change in the connectivity of the green space system in relation to the private-initiative park project. The spatial scope of this study is in Cheongju, Korea. There were 8 private-initiative park projects selected as research subjects. The IIC indicator and d_IIC indicator, which are widely used in the analysis of green space connectivity, were used as analysis methods. Changes in connectivity according to four scenarios were simulated. Upon analysis, the results revealed that private-initiative park projects can reduce the overall connectivity of green spaces. The connectivity of private-initiative park projects can be improved compared to the situation of unplanned development while maintaining the current state. Lastly, changes in connectivity due to private-initiative park projects vary by region. This study was meaningful as an early study that analyzed private-initiative park projects in terms of the connectivity of green areas and is expected to be used for the improvement of the park and green space system in the future.

Ameloblastic fibroodontoma is a mixed odontogenic tumor in very rare occurrence that is composed of proliferating ectodermal mesenchymal component of odontogenic tissues such as enamel and dentin. Its frequency is about 2 percents of all odontogenic tumors, and it usually does not lead to pain. Therefore, it may be unexpectedly detected on gradual facial asymmetry or examination of unerupted tooth. And displacement of teeth have also been frequently reported. Most of ameloblastic fibroodontomas develop in average age of 10 years and rarely occurs in older person. The difference between sexes is similar, and are equally affected on maxilla and mandible, posterior prevalence is also showed. First case is unexpectedly detected in a 17 years-old male on examination of unerupted tooth and the second case is developed in a 13-yeas-old female who showed an asymptomatic swelling of left midfacial area. Each patient is tentatively diagnosed as a ameloblastic fibroodontomas and a genign tumor. Surgical encleation under general anesthesia was performed. the posroperative histologic diagnosis was ameloblastic fibroodontomas. No recurrances and good healing were showed during follow up period of 4 and 3 years from the encleation of the tumor. Now we present two cases of ameloblastic fibroodontomas with differential diagnosis and immunohistochemical charateristics.

The BPA-3MA(bisphenol-A trimethacrylate) in which one of two hydroxy group was substituted by methacrylate was synthesized by reaction of Bis-GMA with methacryloyl chloride. To investigate the possibility to apply BPA-3MA as matrix of composite resin or pit and fissure sealant, BPA-3MA(3MA) or Bis-GMA(GMA) as matrix, TEGDMA as diluent, CQ as photosensitizer, EDMAB as photoinitiator and 5㎛ pyrogenic silica as filler were used for making experimental sealants. In addition, these experimental sealants were compared to a commercial Concise L/C White sealant(CLW, 3M Co, U.S.A.) for flexural strength, diametral tensile strength, amount of abrasion, surface hardness, water sorption and solubility, and degree of conversion. The flexural strength of CLW was the highest value but there was not significant difference with 3MA. Diametral tensile strength of all 3 groups were similar(p>0.05) and the amounts of abrasion of 3MA and GMA were less than that of CLW(p<0.05). The surface hardness of 3MA was higher than that of GMA(p<0.05) but similar to that of CLW. The water sorption of 3MA was less than that of GMA and CLW(p<0.05) and the solubilities of 3MA and CLW were than that of GMA(p<0.05). GMA and CLW were relatively polymerized well as compared to 3MA. From these results, pit and fissure sealant using trifunctional BPA-3MA as matrix had superior physical and mechanical properties to existing Bis-GMA sealant. Furthermore, it will be possible to develop composite resin having superior properties to existing composite resin.

Discectomy is the oldest and most commonly performed operation for the painful temporomandibular joint with internal derangement. It is the one operation for which there are longest follow-up study, with Eriksson, silver, and Tolvanen et al reporting good results in patients about 30 years after discectomy. About 80% to 90% of patients clinically experience relief from pain and dysfunction after discectomy, and interestingly, the results may improve with time. However such as Myrhaug found headache and Poswillo supposed pain and limitation of movement as postoperative complications, even though this operation had the longest follow-up term, several aspects of discectomy remain unclear. The controversies to discectomy for TMJ with pain and dysfunction have laid emphasis only upon clinical results, and then the histomorphological study was planned to evaluate the morphologic change of TMJ after discectomy. To clarify the nature of the change through an observation on the morphologic changes of articular cartilage and subchondral bone of the condyle resulting from experimental unilateral discectomy in rabbit, the author excised the left articular discs of 12 male rabbits(control 4 rabbits), weighing about 3kg, and at 1, 3, 6, 9 weeks following surgery, harvested both(left surgical site and right nonsurgical sits) TMJ. The specimens were examined with light microscope after H-E and MT stain and the obtained results were as follows. 1. Histopathological features showed thickening of articular zone and active proliferation of fibrocartilaginous zone associated with slight proliferative zone in surgical site than control group. Also replacement of chondrocytes in calcified cartilaginous zone into bone cells was observed. 2. There were thinning of thickness of each zone of articular cartilage except calcified cartilagnous zone was observed in nonsurgical site. 3. In MT stain of condylar trabeculae, there was increased calcification in nonsurgical site than control and surgical site and the degree of calcification was similar in surgical site and control group. 4. In both site of experimental group no features of degenerative changes were observed. From the above results, it is presumed that the morphologic changes of surgical site disectomy are compensatory remodeling process characterized by an hyperplastic reaction of the articular zone and fibrocartilaginous zone filling the void created by removing the disc, and the bone changes are secondary to changes in the cartilage. Increased degree of calcification seen in condylar trabeculae of nonsurgical site results from the excessive use of condyle of that site.

Background: To investigate clinical features and risk factors of stroke patients who lived in Korean rural area, we analysis Wonkwang Stroke Registry and compared with other studies. Methods: We filled out Stroke Registry in the consecutive patients with acute ischemic stroke from march 1997 to February 1999. We analyzed demographic data, risk factors and subtypes of stroke. All patients were divied into 3 groups according to their age. Stroke subtype was classified into large artery atherosclerosis(LAA),small vessel occlusion(SVO), cardioembolism(CE), stroke of other determined etiology(SOE), and stroke of undetermined etiology(SUE) by TOAST(Trial of Org 10172 in Actue Stroke Treatment). Results: Five hundred nine patients were included in Wonkwang Stroke Registry from march 1997 to February 1999. Mean age was 65.47±0.48 years old. The ratio of males to females was 1 : 0.78. SVO was the most frequent subtype(49%) of ischemic stroke, and then followed by LAA(27.5%), CE(7%), SOE(8.1%), and SUE(8.4%). The internal carotid artery(ICA) territory was involved in 59.3% patients. Vertebrobasilar artery territory involvement was noted in 37.5%, and 3.2% of patients showed multiple artery territory involvement. All patients had risk factor of ischemic stroke except for 14 patients. Mean number of risk factors was 1.7/patient. Hypertension(62.1%) was the most frequent risk factor, and follwed by smoking(26.3%), diabetes mellitus(25.9%), and hyperlipidemia(25.55%). Conclusions: These results showed that the proportion of ischemic stroke subtype was not concordant with other studies. It may be caused by different mode of living and ethnic difference. This study may afford further information on the characteristics of Korean rural area stroke.
