  • This study was intended to perform the influence of condyle positional change after surgical correction of skeletal Class III malocclusion after BSSRO in 20 patients(males 9, females 11) using computed tomogram that were taken in centric occlusion before, immediate, and long term after surgery and lateral cephalogram that were taken in centric occlusion before, 7 days within the period intermaxillary fixation, 24hour after removing intermaxillary fixation and long term after surgery. 1. Mean intercondylar distance was $84.45{\pm}4.01mm$ and horizontal long axis of condylar angle was $11.89{\pm}5.19^{\circ}$on right, $11.65{\pm}2.09^{\circ}$on left side and condylar lateral poles were located about 12mm and medial poles about 7mm from reference line(AA') on the axial tomograph. Mean intercondylar distance was $84.43{\pm}3.96mm$ and vertical axis angle of condylar angle was $78.72{\pm}3.43^{\circ}$on right, $78.09{\pm}6.12^{\circ}$on left. 2. No statistical significance was found on the condylar change(T2C-T1C) but it had definitive increasing tendency. There was significant decreasing of the distance between both condylar pole and the AA'(p<0.05) during the long term(TLC-T2C). 3. On the lateral cephalogram, no statistical significance was found between immediate after surgery and 24 hours after the removing of intermaxillary fixation but only the lower incisor tip moved forward about 0.33mm(p<0.05). Considering individual relapse rate, mean relapse rate was 1.2% on L1, 5.0% on B, 2.0% on Pog, 9.1% on Gn, 10.3% on Me(p<0.05). 4. There was statistical significance on the influence of the mandibular set-back to the total mandibular relapse(p<0.05). 5. There was no statistical significance on the influence of the mandibular set-back(T2-T1) to the condylar change(T2C-T1C), the condylar change(T2C-T1C, TLC-T2C) to the mandibular total relapse, the pre-operative condylar position to the condylar change(T2C-T1C, TLC-T2C), the pre-operative mandibular posture to the condylar change(T2C-T1C, TLC-T2C)(p>0.05). 6. The result of multiple regression analysis on the influence of the pre-operative condylar position to the total mandibular relapse revealed that the more increasing of intercondylar distance and condylar vertical axis angle and decreasing of condyalr head long axis angle, the more increasing of mandibular horizontal relapse(L1,B,Pog,Gn,Me) on the right side condyle. The same result was founded in the case of horizontal relapse(L1,Me) on the left side condyle.(p<0.05). 7. The result of multiple regression analysis on the influence of the pre-operative condylar position to the pre-operative mandibular posture revealed that the more increasing of intercondylar distance and condylar vertical axis angle and decreasing of condylar head long axis angle, the more increasing of mandibular vertical length on the right side condyle. and increasing of vertical lengh & prognathism on the left side condyle(p<0.05). 8. The result of simple regression analysis on the influence of the pre-operative mandibular posture to the mandibular total relapse revealed that the more increasing of prognathism, the more increasing of mandibular total relapse in B and the more increasing of over-jet the more increasing of mandibular total relapse(p<0.05). Consequently, surgical mandibular repositioning was not significantly influenced to the change of condylar position with condylar reposition method.

  • This paper aims to review all landscaping elements of Donggwoldo by building and identify the palatial garden landscaping characteristics and landscaping methods in a bid to explore landscaping methods applicable for modern-time gardens of Korea through Succession of Tradition. The research methodology was adopted by which the palatial gardens appearing in Donggwoldo were observed according to garden elements to identify their characteristics. Garden elements in Donggwoldo include oddly shaped stones, ponds, buildings and Madang, borders and areas, and trees. Their characteristics were analyzed, and as a result they are outlined as follows. Location : Buildings in Donggwoldo were located in the optimal areas within the Myungdang (the best location), with the building sites being created by transforming the natural topography positively according to the existing topography and uses. Tree planting : The construction of the buildings involved using the existing trees. There were no specific principle and method of planting trees, and no specific criteria for choosing the kind of tree. Symmetrical planting was adopted and its is considered embracing the viewpoint of making gardens based on the expression of Yin and Yang. Strongly symbolical kinds of trees were also adopted. Bangji : it takes a nearly circular shape in palatial gardens, and such shapes represent conceptual and abstract symbols. They were also frequently used as the place of public entertainment. Pavilions : they did not take a certain standard shape. They had diverse shapes, including a triangle, square, pentagon, hexagon, and octagon and cross. Oddly shaped stones : Oddly shapes stones and stone cases were deployed mainly near the bedroom and the crow prince's residence and in the rear garden. Hwagye : it appeared mainly in the back of the bedroom, the crown prince's residence, the princess's residence, and other women's quarters. Chwibyeong : it was installed for the purpose of drawing the natural energy like a natural inlet instead of being the nature-dividing wall. Korea's garden composition method was very different from the Western and Chinese method. Overall, Chosun palatial garden style was characterized by strict and Confucian features, while the garden construction method adopted the Taoism thought. Yet, the gardens had a carefree aspect.

  • The purpose of this study was to compare the arch width of the hyperdivergent group with that of the neutral group in Class III malocclusion based on the vertical patterns and to compare the arch width of Class III neutral group With that of normal occlusion group based on sagittal patterns. The subjects consisted of 118 pairs of studty casts, divided into three groups , 37 Class III hyperdivergent group(18 males and 19 females, SN-Mn plane angle>39.5$^{\circ}$), 40 Class III neutral group(20 males and 20 females, SN-Mn plane angle : 32 ${\pm}$ 2.5$^{\circ}$) and 41 Class I normal occlusion group(20 males and 21 females). The intercanine, interpremolar, and intermolar width of the maxillary and mandibular study casts were measured, then the ratios of dental width to basal width and mandibular width to maxillary width were obtained. Basal arch width and dental arch width were measured to obtain the pure basal arch relation in transverse plane as ruled out the transverse dental compensation. The results were as follows 1. There were no significant differences in any ratios between Class III hyperdivergent group and Class III neutral group as different vertical pattern. 2. As the ratios of dental arch width to basal arch width between normal occlusion group and Class III neutral group were compared, the maxillary teeth flared buccally to the basal bone, and the mandibular teeth tilted lingually to the basal bone in Class III neutral group. 3. The ratios of mandibular arch width to maxillary arch width in basal arch level were significantly different in all regions. Maxillary basal arch width of Class III neutral group was narrower than that of normal occlusion group. 4. The ratios of mandibular arch width to maxillary arch width in teeth level were not significantly different between normal occlusion group and Class III neutral group. In spite of discrepancies of maxillary and mandibular basal arch width, the dental arch width of Class III malocclusion group compensated very well. At the presurgical orthodontic treatment in clinic, it would not be desirable to decompensate for compensated dental arch width too much, for obtaining an appropriate arch compatibility and good results for orthognathic surgery.

  • This study was conducted to investigate the quality characteristics of seasoned pork prepared by Korean traditional 4 types seasoning such as soy sauce (T1); Kimchi sauce (T2); pickled shrimps sauce (T3) and onion sauce (T4). The samples were seasoned by the proportion of meat to seasonings (1:1). The seasoned samples were aged at $1{\pm}1^{\circ}C$ for 30 days. The results obtained were as follows; pH of T3 was higher (p<0.05) than other treatments during aging periods. Saccharinity and salinity were higher in T1. Except T3, water holding capacity (WHC) have no significantly (p>0.05) different during the aging. Shear force and Volatile basic nitrogen (VBN) were increased in T1 and T4 with aging periods. TBARS have no significantly (p>0.05) different in all treatments at the 1 day of aging, however T1 was significantly higher (p<0.05) compared with other treatments after 10 days of aging. In surface meat color, a* and b* were higher in T2 and lower in T4 with aging periods. In inner meat color, L* was decreased in all treatments with aging periods, however T4 was no significantly (p>0.05) different during aging periods. a* and b* were increased with aging periods in all treatments. Total plate counts was increased at the 10 days of aging and decreased at the end of aging. Escherichia coli of T1, T2 and T3 were decreased with aging periods, however T4 was significantly (p<0.05) increased with aging periods. Lactobacilli spp. of T2 and T3 were higher than other treatments at the beginning of aging. In sensory evaluation, T4 was higher at the beginning of aging, however T1 and T3 were increased sensory evaluation value with aging periods.

  • The purposes of the study were to find refined taste of ancestor through historical research about traditional cooking method and ingredient for the purpose of enriching today#s dietary life and to hand down a particular style of regional dish and excellence of nutritional aspect by providing a standard recipe and nutrition analysis data on #Dong-rae Pajeon#. To collect data about traditional ingredients and cooking method, researcher interviewed seven local natives who have kept a traditional food costumes, visited four restaurants, and reviewed ten cookbooks. The interviewees recalled and demonstrated the cooking procedure. The standard recipe of #Dong-rae Pajeon# was created after three experimental cookings, based on the recipes of the natives, restaurants, and cookbooks. According to the natives# statements, #Dong-rae Pajeon# was a special dish that was offered to the king at #Samzi-nal# (March 3rd of the lunar calendar). It was also a seasonal (before cherry blooming time) and memorial service dish of the province#s high society. The main ingredients were small green onion, dropwort, beef, seafood (large clam, mussel, clam meat, oyster, shrimp, fresh water conch), waxy rice powder, non-wax rice powder, and sesame oil which were abundant in Busan and Kijang region. Energy per 100 g of #Dong-rae Pajeon# was 148 kcal. Protein, lipid, fiber, Ca, and Fe contents were 8.8 g, 2.0 g, 8.6 g, 57.7 mg, and 1.8 mg respectively. Contents of cystine, lysine, leucine, valine, isoleucine which are essential amino acids were high in #Dong-rae Pajeon#. Fatty acids contents are oleic acid (20.5%), linoleic acid (20.1%) and linolenic acid (10.4%) while P/M/S ratio was 0.73/0.67/1.

  • Purpose : Before we report the results of curative radiotherapy in cervix cancer patients, we review the significance and safety of our dose specification methods in the brachytherapy system to have the insight of the potential Predictive value of doses at specified points. Matersials and Methods : We analyze the 리5 cases of cervix cancer patients treated with intracavitary brachytherapy in the lateral simulation film we draw the isodose curve and observe the absorbed dose rate of point A, the reference point of bladder(SBD) and rectum(SRD). In the sagittal view of Pelvic MRI film we demarcate the tumor volume(TV) and determine whether the prescription dose curve of point A covers the tumor volume adequately by drawing the isodose curve as correctly as possible. Also we estimate the maximum Point dose of bladder(MBD) and rectum(MRD) and calculate the inclusion area where the absorbed dose rate is higher than that of point A in the bladder(HBV) and rectum(HRV), respectively. Results : Of forty-five cases, the isodose curve of point A seems to cover tumor volume optimally in only 24(53%). The optimal tumor coverage seems to be associated not with the stage of the disease but with the tumor volume. There is no statistically significant association between SBD/SRD and MBD/MRD, respectively. SRD has statistically marginally significant association with HRV, while TV has statistically significant association with HBV and HRV. Conclusion : Our current treatment calculation methods seem to have the defect in the aspects of the nonoptimal coverage of the bulky tumor and the inappropriate estimation of bladder dose. We therefore need to modify the applicator geometry to optimize the dose distribution at the position of lower tandem source. Also it appears that the position of the bladder in relation to the applicators needs to be defined individually to define 'hot spots'.

  • Purpose: This study evaluated the effect of glass fiber pre-impregnated with light-curing resin on the fracture strength and fracture modes of a maxillary complete denture. Materials and methods: Maxillary acrylic resin complete dentures reinforced with glass fiber pre-impregnated with light-curing resin (SES MESH, INNO Dental Co., Yeoncheongun, Korea) and without reinforcement were tested. The reinforcing material was embedded in the denture base resin and placed different regions (Control, without reinforcement; Group A, center of anterior ridge; Group B, rugae area; Group C, center of palate; Group D, full coverage of denture base). The fracture strength and fracture modes of a maxillary complete denture were tested using Instron test machine (Instron Co., Canton, MA, USA) at a 5.0 mm/min crosshead speed. The flexure load was applied to center of denture with a 20 mm diameter ball attachment. When fracture occurred, the fracture mode was classified based on fracture lines. The data were analyzed with one-way ANOVA at the significance level of 0.05. Results: There were non-significant differences (P>.05) in the fracture strength among test groups. Group A showed anteroposterior fracture and posterior fracture mainly, group B, C and control group showed partial fracture on center area mostly. Most specimen of group D showed posterior fracture. Conclusion: The location and presence of the fiber reinforcement did not affect the fracture strength of maxillary complete denture. However, reinforcing acrylic resin denture with glass fiber has a tendency to suppress the crack.

  • The aim of the present study was to evaluate the effect of marination with mixed salt (NaCl, $CaCl_2$, and phosphate) and kiwi juice and of different cooking methods for pork loin-based products in order to establish the basic database for increasing the consumption of pork loin in Korea. Diced chilled pork loin ($2{\times}2{\times}2\;cm$) was marinated in 4 different treatments: no additives (T1), salt mix only (T2), kiwi juice only (T3), and salt mix+kiwi juice (T4). The mixed salt was prepared by the addition of NaCl, $CaCl_2$, and phosphate dissolved in water (10% of pork loin weight) at concentrations of 0.5, 0.5, and 0.3% per pork loin weight, respectively. The amount of kiwi juice was 10% of pork loin weight. After marination for 24 hrs at $4^{\circ}C$, the samples were cooked with different methods including roasting with Kimchi, pan broiling, and simmering. After simmering, pH of pork loin of T1 and T2 was higher than that of T3 and T4 (p<0.05), while that of roasted with Kimchi and pan broiled did not show any difference. Water holding capacity of T4 after pan broiling was higher than that of T1, T2, and T3 (p<0.001) and shear force of T4 was lower than other treatments. Also flavor and acceptability of T4 after pan broiling were scored higher by 11 sensory panelists (p<0.05). From this result, the pork loin-based products marinated with mixed salt and kiwi juice with pan broiling would be preferred by consumers as one of the methods to promote the consumption of pork loin in Korea.
