  • In this study, six historical parks in Seoul is analyzed. Based on the analysis, the representative values of the historical parks in Seoul draw three criteria such as historicity, educational attributes, and sociality, and also the type of historic and cultural resources, spatial functions and arrangements, circulation and accessibility, and the type and usage of introduced facilities. Consequently the current status and improvement plan is suggested as follows. First, cultural assets oriented historical parks such as Sayuksin Bongeun and Seonnongdan historical Park focus on the management based on the preservation of historic and cultural resources. Non designated cultural heritages oriented historic parks such as Shingye Yanghwajin Itaewon-bugundang historic park should focus on the usages the symbolize and commemorate historic and cultural resources. Second, Careful attitudes on the historicity of the park are needed in the mixed type of historic and cultural resources that determine the identity such as Yanghwajin Itaewon-bugundang historic park. Third, the rate of facilities in Bongeun and Shingye historical park is increased due to the renovation of religion facilities, rather than the neighborhood parks. The autonomy of regulations that does not have the limits of the area of park facilities weaken the publicity of the historical parks. Fourth, Shingye historical park suggest changing its name into Danggogae martyrs' shrine historical park. because its historic and cultural resources are included as the historic park is named. Fifth, the current problems such as numerous uncontrolled entrances, mixed uses in circulation, and accessible failure due to the closure are recognized. Therefore, the entrances and circulations should be articulated clearly in order to increase opportunities of experience for visitors in the historic and cultural resources, and also neighborhood facility should be suitably divided. Sixth, the park facilities in the neighborhood parks are introduced equally in Seoul historical parks. The uses and arrangements that considered the circumstance of the historical parks should be determined in the cultural facilities such as outdoor music hall and sporting facilities. Seventh, historic facilities that named historic hall, culture hall, memorial hall, and promotion hall in the historic parks are utilized for convenience and religion facilities. Institutional framework should be examined to keep publicity in the historic parks by spatial privatization of the specific group.

  • Background: Sternal wound infection (SWI) is an important complication after cardiac surgery. The aim of this study was to investigate the predictors affecting sternal wound infection and preventive factors including short term Vancomycin therapy in patients who underwent coronary artery bypass grafting (CABG). Material and Method: A retrospective study was done using data collected from January 2001 through December 2007. This included 219 patients who had isolated CABG. The definition of SWI was documentation from a microbiological study and a requirement for simple closure or other surgical revision. Result: The overall incidence of SWI was 7.8% (n=17). The causative organisms were methicillin resistant Staphylococcus aureus (MRSA, n=13), methicillin resistant Staphylococcus epidermidis (n=2), Pseudomonas aeruginosa (n=1), and Candida albicans (n=1). Ten cases had deep sternal wound infection with mediastinitis; 7 cases had a superficial wound infection. Infection-related mortality was low (1/17; 6%). Diabetes mellitus (p=0.006) and smoking history (p=0.020) were factors that predicted high risk. Short term use of vancomycin decreased the incidence of MRSA-associated SWI (p=0.009). For treatment, curettage and rewiring or flap were needed in most cases (88%, n=14). Conclusion: Patients who had diabetes mellitus and a smoking history need careful management. Short term use of vancomycin is effective for prevention of SWI with MRSA.

  • The author reviewed the medical records of 96 typhoid fever patients who were diagnosed, admitted, and treated at Sea grave Memorial Hospital from January 1 , 1973 through August 31, 1975. Diagnosis was determined by clinical observation, aerology and bacteriology, eighty patients were treated medically, the remaining 16 patients required surgical intervention. The following results were obtained: 1) The age distribution of the patients revealed that 33.3% wert between 10 and 19 years old 21.9% were between 20 and 29, and 19.8% were between 30 and 39. The majority of patients were from these more active age groups. Male to female sex ratio was 1.3 : 1 2) Seasonal distribution was observed. Most illness occurred in the summer and autumn month 5. 3) 84. 3%of the patients came from farm families. 4) Duration between onset and admission averaged 16.0 days. The group without compilations was admitted after an average of 15. 1 days; The group with complications was ad-matted after an average of 19.4 days. 5) Methods of treatment before admission were as follows: 10.4% at medical clinics, 61, 5% at pharmacies (antibiotics 47.9%, other. drugs 13.5%), 7.3% by herb medications, 20.8% had no treatment. 6) Main clinical symptoms were as follows: fever 93.8%, headache 47.9%, abdominal pain 47.9%, chills 38.5%, cough 36.5%, general weakness 26.0%, nausea e vomiting 24.0% and generalized pain 21.9%. 7) Temperature of patients on admission: 22.9% were 39f or more, 67.6% were between 37℃ and 38℃, and 9.4% were 37℃ or less. 8) Occurrence of intensional bleeding after onset of disease averaged 9.3 days; perforation occurred at an average of 19. 1 days. 9) Interval between onset of major complication and surgical intervention averaged 2.8 days. 10) Among the 68 patients who underwent the bacteriological test the positive rate was 44.1% (30). The positive ,ales to, each separate culture method were as follows: 20.4% in the blood culture, 40.4% in the stool culture and 6.7% in the urine culture. Among these bacteriological positive patients 15 patients had a negative results or less than 160 titer of vidal reaction. 11) The initial vidal test of the total group showed a counts of 160 titer or more in 60.4% and less than 160 titer in 39.6%, 12) W. B. C. Counts in the uncomplicated group indicated that 32.5% were 6,000/㎣ or less, 47.5% were between 6,000 and 10,000, arid 20.0% were 10,000/㎣ or more. In the complicated group, 37.6% were 6,000/㎣ or less, 25,0% were 6,000-10,000/㎣ and 37.6% were 10,000/㎣ or more. 13) Duration of hospital stay of the patients averaged 6.4 days in the uncomplicated group and 12.7 days in the complicated group. 14) Subdiaphragmatic free air simple X-ray was found in 91.7% of the perforated cases. 15) Duration of antibiotic therapy until an febrile state was attained averaged 4.8 days in the uncomplicated group and 6.5 days in the complicated group. 16) Operative procedures were as follows: one layer simple closure of their perforation with or without debasement in 56.3%, drainage only in 6.3%, small bowel resection with primary anastomosis in 18.8% , externalization in 6.3%, cholecystectomy in 6.3%, The clinical findings of this study suggest the following recommendations. According to Top's report; 1% of typhoid fever patients treated with chlorarnphenicol and 2% of patients treated with other drugs become chronic carriers. Therefore, importance should be given to the strict control of these carriers. Immunization, improvement of sanitation and living standards are all needed for the prevention and treatment of disease, but a more serious problem is a lack of knowledge on the part of patients and their families. Thus it is most urgent to enlighten the citizens about the transmission and hygiene related to contagious disease. Legal restriction of sale of antibiotics at drug stores without a physician's prescription is an urgent matter for public health administrators. An even more important nursing responsibility is the reemphasis on health education both in the clinical setting and in the home.

  • Objective: When an alveolar cleft is too large to close with adjacent mucobuccal flaps or large secondary fistula following a primary bilateral palatoplasty exists, a one-stage procedure for bone grafting becomes challenging. In such a case, we used the tongue flap to repair the fistula and cleft alveolus in the first stage, and bone grafting to the cleft defect was performed in the second stage several months later. The purpose of this paper is to report our experiences with the use of an anteriorly-based Y-shaped tongue flap to fit the palatal and labial alveolar defects and the ultimate result of the bone graft. Patients: A series of 14 patients underwent surgery of this type from January 1994 to December 1998.The average age of the patients was 15.8 years old (range: 5 to 28 years old). The mean period of follow-up following the 2nd stage bone raft operation was 45.9 months (range: 9 to 68 months). In nine of the 14 cases, the long-fork type of a Yshaped tongue flap was used for extended coverage of the labial side alveolar defects with the palatal fistula in the remaining cases the short-forked design was used. Results: All cases demonstrated a good clinical result after the initial repair of cleft alveolus and palatal fistula. There was no fistula recurrence, although Partial necrosis of distal margin in long-forked tongue flap was occurred in one case. Furthermore, the bone graft, which was performed an average of 8 months after the tongue flap repair, was always successful. Occasionally, the transferred tongue tissue was bulging and interfering with the hygienic care of nearby teeth; however, these problems were able to be solved with proper contour-pasty performed afterwards. No donor site complications such as sensory disturbance, change in taste, limitations in tongue movement, normal speech impairments or tongue disfigurement were encountered. Conclusion: This two-stage reconstruction of a bilateral cleft alveolus using a Y-shaped tongue flap and iliac bone graft was very successful. It may be indicated for a bilateral cleft alveolus patient where the direct closure of the cleft defect with adjacent tissue or the buccal flap is not easy due to scarred fibrotic mucosa and/or accompanied residual palatal fistula.

  • Pulmonary atresia with intact ventricular septum has continued to have a high surgical mortality and morbidity. This mAy attribute to the non-uniformity of the anomaly. We reviewed a total of 34 infants with pulmonary atresla and intact ventricular septum managed in this hospital between 1987 and 1995. Mean age and body weight were 57.2 (range, 3-208) days and 4.1 (range, B.3∼6.8) kg. The preoperative Z-value of the diameter of the tricuspid valve was less than -2 in 85.2% of patients and less than -4 in 33. 3% . It is well correlated w th right ventricular cavity size (n=27. r10.68, p< 0.05). Coronary artery-right ventricular fistulas were identified in 3 patients, and right ventricular dependency was suspected in 1 Over All hospital mortality was 23.5%(8/34), although it decreased to 16.6%(4124) in 1990s. Subsequent procedures were performed in 6 patients between 3 days and 58 months after Initial palliation : one bidirectional cavopulmonary shunt and 1 Fontan operation after systemic-pulmonary shunt, 3 transannular patch + atrial septal defect closure and 1 additional systemic-pulmonary shunt after polmonary valvectomy or valvotomy. Changes of Z-values of the diameter of tricuspid valve have been followed up in 11 patients between 1 and 66 months postoperatively. Z-values were increased In 5 out of 8 transannular right ventriculAr outflow tract enlargement group and in 1 out of 3 pulmonary valvectomy or valvotomy group. Our data suggest that tailoring a treatment to right ventricular cavity size and coronary anom lies may improve the surgical outcome. A Z-value of the tricuspid valve diameter could be used.

  • The purpose of this study was to investigate the histologic changes in mandibular periodontium during overbite closure for openbite treatment by continuous arch wires and anterior vertical elastics. Two female monkey(Macaca nemestrina) with permanent dentition were used. Posterior bite block was fixed to each of their maxillae, which made the animal temporary anterior openbite as well as stabilized the whole maxillary anchorage. In each mandible, all the teeth except the second molars which had been extracted, were prepared for cast crowns. 018 inch Standard brackets were welded on these crowns. After cementation, two types of the $016{\times}022$ inch continuous arch wires, the plain ideal arch to the control animal and the MEAW(multiloop edgewise archwire) to the other experimental one were inserted. Then anterior vertical elastics were applied for two weeks. The overbite depth changes in the monkeys and histologic examinations of the mandibular periodontiums suggested the following conclusions. 1. During two weeks of the experimental period, the overbite increased + 0.3 mm in the control and + 1.3 mm in the experimental one. 2. In both the control and the experimental animal, histologic examinations showed that incisors, canines and first premolars were subject to extrusive force and the rest of posteriors were subject to intrusive one. 3. In periodontiums of the extruded incisors of the experimental one, reorientation of the periodontal fiber structures reflected the direction of force and the alveolar bone surfaces including apical and crestal areas which had been subject to tension, were the front of new bone formation. 4. In periodontiums of the extruded incisors of the experimental one, neither excessive hyalinization nor gross root resorption was observed. 5. Alveolar bone remodeling of anteriors and posteriors was more remarkable in the experimental one than the control.

  • The purpose of this study is to investigate the influence of the Korean Wave on Chinese tourism to South Korea through a behavioral analysis of Chinese tourists in the general group package tours. China suppressed the needs of the Chinese people's geographical movement and imposed restrictions on information about the outside world with the use of a policy of "closure" for a long time. But since reforms and open-door policies were introduced in China, especially in the context of relaxation of control policies over Chinese outbound tourism after the mid-1990's, more and more Chinese make trips abroad including visits to South Korea. In this situation, the recent Korean Wave(especially, drama/film) describes the Korean national image by forming a bridge between fiction and reality and plays a pivotal role in broadening or reconstructing the geographical imagination of the Chinese people who have been historically isolated from the outside world. Although Chinese have imagined the Korean nationscape on the basis of geopolitical or economic factors in the past, they have currently broadened or reconstructed their geographical imagination to include socio-cultural factors related closely to the Korean way of life due to the recent Korean Wave. This newly constructed geographical imagination led by the Korean Wave functions as an important pulling factor in Chinese destination choices, affecting Chinese tourists' motivation formation and the recommendation of main attractions. The more influential the Korean Wave is on their destination choice, the more the respondents select the cultural factors in both their motivation for tourism to South Korea and their recommendations of tourism attractions to other people. Through the analysis results of both satisfaction and intention to revisit, the more influential the Korean Wave is on their destination choice, the higher is the degree of both satisfaction and intention to revisit. In other words, although Chinese tourism to South Korea is chiefly in the general group package tours, Chinese tourists who are influenced by Korean Wave on their destination choice have more attachment to(or affection for) Korea as a tourism destination. This result suggests that the Korean Wave affects qualitative change - that is, change of attitude - as well as quantitative change in Chinese demand for tourism to South Korea.

  • This study aims to analyze the voices of the patients with voice disorders including vocal fold paralysis, vocal fold cyst and vocal nodule/polyp in the aspect of acoustic phonetics. This study intends to collect subsidiary acoustic data in order to make a speech treatment and an standardization of vocal disorders. Subjects and Methods: The subjects of this study were 64 adult patients who underwent indirect laryngoscopy and laryngostroboscopy, and were diagnosed as vocal fold paralysis, vocal fold cyst or vocal nodule/polyp. Experimental group consisted of 20 patients who were diagnosed as vocal fold paralysis, 21 patients who were diagnosed as vocal fold cyst and had the average age of 42.0 $({\pm}10.03)$ ; and 23 patients who were diagnosed as vocal nodule/polyp and had the average age of 40.9 $({\pm}13.75)$. For the methodology of this study, the patients listed above were asked to sit in a comfortable position at intervals of 10cm apart from the patient's mouth and a microphone, and subsequently to phonate a vowel sound /e/ for the maximum phonation time with natural tone and vocal volume then the sound was directly inputted on a computer. During recording, sampling rate was set to 44,100Hz and the 1-second area corresponding to stable zone except the first and the last stage of waveform of the vowel sound /e/ vocalized by the individual patients was analyzed. Results: First, there was no statistically significant difference in jitter and shimmer between vocal fold paralysis and vocal fold cyst, while there was highly statistically significant difference in them between vocal fold paralysis and vocal nodule/polyp. Second, looking into the mean values obtained from NNE, HNR and SNR results associated with noise ratio, the disease showing the most abnormal characteristics was vocal fold paralysis, followed by cyst and nodule/polyp in order. For NNE, there was statistically significant difference between vocal nodule/polyp, and cyst or paralysis. In other words, it was found that the NNE of vocal nodule/polyp was weaker than that of cyst or paralysis. Similarly, HNR and SNR also showed the same characteristics; there was statistically significant difference between vocal fold paralysis and vocal fold cyst or nodule/polyp, and HNR and SNR values of vocal fold paralysis were lower than those of vocal fold cyst or nodule/polyp. Conclusion: For vocal fold paralysis, the abnormal values of acoustic parameters associated with frequency, amplitude and noise ratio were statistically significantly higher than those of vocal fold cyst and nodule/polyp. This finding suggests that the voices of the patients with vocal fold paralysis are the most severely injured due to less stability of vocal fold movement, asymmetry and incomplete glottic closure. In addition, there was no statistically significant difference in the acoustic parameters of tremor among vocal fold paralysis, vocal fold cyst and vocal nodule/polyp. Further studies need to ascertain reasonable acoustic parameters with various vocal disorders as well as to clarify the correlation between acoustics-based objective tools and subjective evaluations.

  • $^{40}Ar/^{39}Ar$ analytical data of hornblende and muscovite separates from granitic rocks in southwestern region of Ogcheon belt shows fellowing tectonic implication, $^{40}Ar/^{39}Ar$ data of 5 samples yield apparent age spectra and $^{37}Ar_{ca}/^{39}Ar_k$ and $^{38}Ar_{CI}/^{39}Ar_k$ plateaus for more than 60% of the $^{39}Ar$ release. Except for HN-100, the $^{36}Ar/^{40}Ar$ versus $^{39}Ar/^{40}Ar$ corelalation diagrams indicate the presence of one distint line. Muscovite of sample PKJ-44 yield flate apparent age plateau for > 60% of the $^{39}Ar_k$ release. In the high temperature steps, the $^{37}Ar_{ca}/^{39}Ar_k$ values are irregular with a correlative increase in $^{38}Ar_{CI}/^{39}Ar_k$, suggesting some Ca and CI rich phase, tapped between the silicate sheet is being argon degassed. The $^{40}Ar/^{39}Ar$ total gas age and the high temperature age of HN-100 is 918.2 Ma and 1360 Ma, respectively. The former affectted by recystallized age of Daebo Orogeny, and the latter indicated age of hornblende closure temperature for cooling stage of amphibole xenolith in granite gneiss. Three rock types of Kwangju granites show about 165 Ma hornblende and muscovite ages with some degassed argon at low temperature steps. These ages of 4 samples indicate also recrystallized age by Daebo Orogeny. In $^{40}Ar/^{39}Ar$ mineral age, Rb/Sr whole age and K/Ar mineral age, discordant ages of southwestern region of Ogcheon belt suggesting cooling rates approaching 3~4$^{\circ}C$/m. y. Such slow cooling rates can be produced by uplift rate of 100m/m.y. or slightly slower than isothem-migration rate derived from the hornblende samples. We conclude that the strongest Orogeny and igneous activity of southwestern region of Ogcheon belt are middle proterozoic era (about 1360 Ma) and middle Jurassic period (about 165 Ma).

  • This study was performed to evaluate the efficacy of sodium carboxymethylcellulose (SCMC) for the prevention of postoperative uterus and ovary adhesion formation in the Korean black goats. Twenty adult female Korean black goats randomly were divided into five groups with four animals in each group. After the routine laparotomy, catheter for injection was inserted into the abdomen. Before abdominal closure, saline, 1% SCMC, 2% SCMC or 0.4% HA solution (50ml/10kg of body weight/head) were injected in the abdominal cavity in each group. Three weeks after surgery, second laparotomy was performed and the adhesions were scored on a scale of 0 to 10 according to their vascularity and adhesion size in uterus and ovary. This trial was repeated the four times with the interval of three weeks. In the first and second trial, the group treated with 2% SCMC significantly reduced the adhesion formation than other treatment groups (P<0.05). In the third trial, the adhesion formation was significantly reduced in 2% SCMC and 1% SCMC (P<0.05). In the fourth trial, 2% SCMC reduced the adhesion formation. However, there was no significant difference among other groups. This study showed that the 2% SCMC administered at the end of the surgery reduced the adhesion formation in the Korean black goats.
