Purpose: This study was performed to investigate the incidence, types of fracture, treatment, associated fracture and complications in patients with nasal bone fracture. Materials and methods: Clinical examination, patient's records and radiographic images were evaluated in 230 cases of nasal bone fractures who were treated at the Department of Oral and Maxillofacial Surgery, Chonnam National University Hospital for recent 5 years; from January 2002 to December 2006. Results: 1. The age of patient was ranged from 4 to 77 years (mean age=36.6 years); Males was 75.7% (n=174), and females 24.3% (n=56). 2. The cause of the nasal bone fracture in this study was a fall or slip down (28.8%, n=66), sports accident (26.0%, n=60), fighting (21.3%, n=49), traffic accident (9.6%, n=22), industrial trauma (7.8%, n=18), and the others (6.6%, n=15). 3. For the patterns of fracture, simple fracture without displacement occured in 10.4% (n=24). Simple fracture with displacement without septal bone fracture was found in 49.5% (n=114). Simple fracture with displacement in company with septal bone fracture showed in 32.6% (n=75). Commiuted fracture with severe depression was presented in 7.4% (n=17). 4. The reduction the displaced nasal bone was carried out in 2 to 10 days (mean 6.8 days) after the injury. 5. Nasal bone fracture associated with Le Fort I fracture (6.5%, n=6.5), Le Fort II fracture (7.4%, n=17), Le Fort III fracture (1.3%, n=3), NOE fracture (13.9%, n=32), ZMC fracture (17.4%, 40), maxillary bone fracture (8.3%, n=19), orbital blow-out fracture (15.7%, n=36), frontal bone fracture (1.3%, n=3) and alveolar bone fracture (10.9%, n=25). 6. The major type of treatment method was closed reduction in 90% (n=207), open reduction in 3% (n=7), and observation in 7% (n=16). 7. There were some complications such as ecchymosis, hyposmia, hypo esthesia and residual nasal deformity which are compatible. Open rhino-plasty was conducted for 3 patients who had residual nasal deformity. Conclusions: These results suggest that most of nasal bone fractures are occurred physically active aged groups(age 10-49 years) and could be treated successfully with closed reduction at 7 days after the injury.

In this study, we aimed to estimate value of water quality improvement in terms of bloom-forming algae case. Evaluation subjects were chosen as general public who had an experience on the tap water usage. This study set up six price categories, which are 5,000, 10,000, 20,000, 30,000, 40,000 and 50,000 Korean won (KRW), through preliminary inquiries and then conducted nationwide surveys aimed at major cities. From those investigations, a total of 1,745 samples were used to conduct the empirical analyses. Main results on applying double-bounded dichotomous choice of contingent valuation method (CVM) are as follows. First, the high social class recognized by the general public, postive attitude toward environmental protection, and high level of understanding about sewage treatment process were statistically significant to willingness to pay (WTP) in support of waterbloom removal. On the other hand, the people who experienced contaminated tap water, have a negative attitude toward environmental protection, or believe that current water costs are expensive, did not favor national project so that WTP was on the lower level. Economic benefit by water quality improvement indicates roughly 590 billion KRW.

Purpose – The purpose of this study is to understand and predict changes in the behavior of domestic tourists by implementing market segmentation according to tourist activities in the post Covid-19 era, and identifying the demographic characteristics and tourist behaviors of each segment. Design/Methodology/Approach – A two-step cluster analysis was conducted by applying eight items from the data of the 'Korea National Tourism Survey 2021', and then the five types of 'Gourmet tasting (GT)', 'Eco-healing (EH)', 'Recreational activities (RA)', 'Shopping experience (SE)', and 'History exploration (HE)' were derived. As a result of cross-tab and ANOVA, there were obvious differences in demographic characteristics and tourist behaviors among types. Specifically, the results of estimating the core determinants of each segmented market through the multinomial logit model are as follows. Findings – First, popularity of tourism destinations and website information are important for GT tourists. Second, ET tourists have high satisfaction with transportation convenience, human service, and tourism destination crowdedness, but spend less on tourist expenditures and the number of trips. Third, RA tourists place value on lodging trips with families, but the participation of those in their 50s and older tends to be low. Fourth, SE tourists have a lot of high-income earners residing in non-metropolitan areas, and are dissatisfied with the tourism destination crowdedness. Fifth, HE tourists consider the popularity of tourism destinations and family lodging trips as important. Research Implications – In this study, a single type regarding the natural tourism resource was not derived. However, there was a high correlation between GT, EH, and RA types, which implies that an appreciation of nature and scenery functions as a foundational element of tourism activities.

동정맥성 기형환자에 있어서 Halothane 마취하 외과적 절제술후에 발생한 전기성 간염
오희균(Hee Kyun Oh),김건중(Geon Jung Kim),윤영수(Young Su Yun),박재관(Jae Kwan Park),유선열(Sun Youl Ryu) 대한악안면성형재건외과학회 1988 Maxillofacial Plastic Reconstructive Surgery Vol.10 No.1
This is a case report of fulminant hepatitis following feeding artery ligation and surgical excision of arteriovenous malformation on left mandibular body in 27-year old female patient under halothane anesthesia. On the 11th postoperative day, sudden high fever (39℃) with nausea, abdominal pain and insomnia were noted. The serum transaminase (SGOT, SGPT) levels were markedly elevated. She had received 10 pints of blood during operation, but HB antigens were negative. On the 14th postoperative day, generalized jaundice, hypoglycemia and oliguria with renal dysfunction were noted. She was diagnosed as fulminant toxic hepatitis with hepatorenal syndrome possibly due to halothane in semicomatous mental state with ascites on the 17th postoperative day, and then transferred to the dept. of internal medicine. About 54 days after operation, she was discharged with symptomatic improvement and almost normal laboratory data through the symptomatic and supportive treatment without corticosteroid. UHFH (Unexplained Hepatitis Following Halothane) or halothane hepatitis has been known as a rare but significant complication following halothane anesthesia. Halothane hepatitis remains controversial in incidence, etiology, differential diagnosis with other hepatitis and prevention. More research and identification on halothane hepatitis are recommended in that halothane is to be the one of significant causes of acute hepatic toxicity following surgery under halothane anesthesia and at present is the most widely used anesthetic agent for a great variety of surgical procedure in our department of oral and maxillofacial surgery.

In this study, we aimed to address a lack of understanding about boutique hotel employees` organizational behavior (OB) in Korea. We built an exploratory research model wherein organizational identity (OI) mediates the effect of perceived person-environment fit?conceptualized by person-organization fit (POF), person-supervisor fit (PSF), and person-co-worker fit (PCF)?on organizational citizenship behavior (OCB) and turn-over intention (TI), assuming that internally differentiated hotel circumstance influence OB. Using data from 252 surveys collected from five-star hotel employees, we empirically tested the model with two groups: boutique hotels and commonly-known brand hotels (i.e., classic hotels). The comparatively analyzed results are as follows: (1) OI was moderated by hotel type (boutique vs. classic). Specifically, the boutique group had a more elastic growth rate for POF, whereas the classic hotel did for PSF. (2) PCF was positively significant on OI in both groups, but POF was effective solely in the boutique group, whereas PSF had an effect only in the classic group. (3) POF and PCF positively influenced OCB; however, PSF was not significant in either group. (4) Only PSF was negatively related to TI in the boutique hotel, whereas POF revealed a negative impact only in the classic one. (5) Mediation effect by OI was significant to POF and PCF on OCB in the boutique group (partially mediated) and the classic one (fully mediated), but the mediation effect on TI was significant only in the boutique group by the full mediation of PSF and PCF.
