This dental anthropological study was performed to analyse male and female students of Che-ju high school students. Cephalometric X-rays and dental casts were obtained of 60 male and 60 female students and the Mean and Standard Deviation were obtained. There was no difference in craniofacial morphology between male and female students but the size of craniofacial skeleton of the male is bigger than that of the female. The distance from NB line to pogonion is longer in the male group, and it meant that mandibular symphysis of the male is well developed than the female. The size of teeth of the male is larger than that of the female and is significant in upper and lower canine and first molar. The size of upper arch width, intercanine width, basal arch width and lower basal arch width of the male is larger than that of the female, but arch length of the male and the female showed no significant difference.

A new species and 2 new records of lichen genus Buellia were discovered from Chuja-do Island in Jeju Province during a recent floristic survey: B. chujana X. Y. Wang, S. Y. Kondr., L. Lőkös & J.-S. Hur sp. nov., B. halonia (Ach.) Tuck., and B. mamillana (Tuck.) W. A. Weber. The new species is characterized by a brown, areolate thallus, the presence of perlatolic acid, and a saxicolous habitat. Together with previously recorded species, 10 Buellia species were confirmed from Jeju-do Island. Among these species, 3 growing in the exposed rocky area contained xanthone (yellowish lichen thallus, UV + orange), indicating that production of xanthone in this genus might be a defense strategy against the harm of UV light. Although the genus Buellia has been thoroughly studied in Korea before, novel species have been discovered continuously, and large species diversity has been found in this crustose genus, even from a small rocky island. This study indicates that the coastal area harbors a vast number of crustose lichen species, and there is great potential to discover unknown lichens in the coastal rocky area in Korea.

The crustose lichen genus Pertusaria comprises over ca. 800 species worldwide. In total, 20 Pertusaria species were localized to the Mt. Sorak and Jeju-do in Korea. To date, information regarding the distribution of Pertusaria species in the South Korean peninsula is scarce. In this study, we collected Pertusaria species across South Korea and identified them based on morphological, chemical, and molecular characteristics. Of the 387 samples collected, we identified 24 taxa and 1 variety, of which 17 were previously recorded, and 6 taxa were newly found in South Korea (P. leioplaca, P. leucosora var. violascens, P. texana, P. thiospoda, P. thwaitesii, and P. xanthodes), 2 known species were transferred to Varicellaria (Varicellaria lactea and V. velata), one species was transferred to Variolaria as a new record (Variolaria multipunctoides) and one was a new species (P. jogyeensis J. S. Park & J.-S. Hur, sp. nov.). Characteristics of the newly discovered species, P. jogyeensis, are as follows: smooth to bumpy thallus, scattered to crowded poriform apothecia, blackish ostioles, definitely sunken, thin yellowish green rims around ostioles, 8-spored ascus, and the presence of perlatolic acid and thiophaninic acid (chlorinated xanthone). Phylogenetic studies on P. jogyeensis based on the mitochondrial small subunit sequence revealed proximity to P. flavicans and P. texana, and supported its classification as a new species within the genus Pertusaria. Additionally, we describe the chemical composition and morphology of all listed species in detail and provide an artificial key for identification.

The purpose of this study was to explain the relationship of professional self-concept, self-efficacy and job satisfaction among nephrology nurses. The subject consisted of 84 nephrology nurses who work at 17 hospitals in Kwangju, Chonnam, Chonbuk and Cheju-do. The instrument of this study was a structured questionnaire on professional self-concept, self-efficacy and job satisfaction. The data were collected from August 16 to September 10, 1999 and analyzed by Cronbach alpha, descriptive statistics, t-test, ANOVA, Scheffe's test and Pearson's correlation coefficient by using the SPSS/PC+ program. The results of the research were as follows: 1. The average item scores were 2.73 for professional self-concept and 7.16 for self-efficacy. The average item score of job satisfaction was 3.05. Professional status (3.56) among the component factors of the job satisfaction had the highest value followed by the interaction(3.46), task requirements(3.28), autonomy(2.98), organizational requirement(2.70), and pay(2.22) was the lowest. 2. The relationship between general characteristics and professional self-concept shows a significant difference with regard to position and the nurses' intention to stay. The relationship between general characteristics and self-efficacy shows a significant difference with regard to position and shift. 3. A significant positive correlation between professional self-concept and self-efficacy (r=0.462, p<0.01) was found. A significant positive correlation between professional self-concept and job satisfaction(r=0.486, p<0.01) was found. In conclusion, professional self-concept and job satisfaction of nephrology nurses are significantly related. A professional self-concept is an important factor for job satisfaction of nephrology nurses. Therefore, this study suggested that we should develop programs and policies to increase the professional self-concept of nephrology nurses for their job satisfaction.

The aim of this study was to reveal the current status of forensic practice in Cheju. The range of subjects was limited to deaths autopsied in Cheju National University during the years of 1998 through 1999. All subjects were reviewed with respect to age, sex, cause of death and manner of death. The total number of deaths was 100, of these 85 cases were males and 15 were females. In age distribution, the age group of 30-39 occupied the highest proportion(25.0%). According to the manner of death, the cases of violent deaths were 78, natural deaths 20, and unknown cases 2. For the violent deaths, the percentage of accidental death was 30.8 and homicide 25.6, suicide 18.0, undetermined cases 25.6. According to the cause of death, asphyxia was the most common (35%), followed by injury(31%) and disease(20%). Among 35 deaths of asphyxia, 24(68.8%) were deaths due to drowning. Medicolegal scene investigation was done in 16 cases. Two cases remained as deaths of unknown cause because of severe decomposition

PURPOSE: There were a few reports for epidemiologic changes of rotavirus gastroenteritis during recent several years in Korea. We tried to know what is characteristics for the prevalence of rotavirus gastroenteritis in Jeju different from epidemiology of the other domestic area. METHODS: We performed a retrospective study of 211 patients with rotavirus gastroenteritis admitted to the pediatric ward at Cheju National University hospital, from December 2001 to June 2005. We defined as rotavirus infection that was positive on immunochromatography method applied to stool samples. RESULTS: Two hundred eleven patients with rotavirus gastroenteritis consisted of 13 patients in December 2001, 32 in 2002, 79 in 2003, 48 patients in 2004 and 39 in 2005 (until June). The monthly distributions, during 3 years from 2002 to 2004, were 40 patients (25.2%) in Jaunary, 56 (35.2%) in February, 31 (19.5%) in March and 23 (14.5%) in April. From May to December, there were only 9 patients (5.6%). Therefore, the prevalences of rotavirus gastroenteritis were concentrated on the 4 months (94.4%) including January, February, March and April. Also, the changes of the monthly distributions from January 2002 to June 2005 were not present. CONCLUSION: In recent years, the monthly distributions of rotavirus gastroenteritis in Jeju area were centered on the 4 months from January to April without prominent seasonal variation.

OBJECTIVE : To describe transitions of positional downbeating nystagmus (PDN) to or from the benign positional vertigo (BPV) involving the posterior (PC) or horizontal semicircular canal (HC). BACKGROUND : PDN occasionally occurs during Hallpike maneuver, and has been ascribed to BPV involving the anterior semicircular canal (AC-BPV). Method : Of the 168 patients diagnosed as having BPV in the Dizziness Clinic of Cheju National University Hospital over the past 2 years, three showed transitions of PDN which occurred during Hallpike maneuver. All the patients received full neurotological examinations. The diagnosis of BPV was based on the typical nystagmus concurrent with vertigo elicited by positional maneuvers. The nystagmus was observed by using Frenzel glasses. Nystagmus was also analyzed by using a video camera or video-oculography, as needed. RESULT : Two patients initially presented with torsional downbeating nystagmus during Hallpike maneuver. The torsional component beat toward the uppermost ear. Both patients later developed the PC or HC type of BPV in the uppermost ear. Another patient developed torsional upbeating nystagmus during Hallpike maneuver, consistent with right PC-BPV, following a motor vehicle accident. After Epley maneuver, the nystagmus was transformed into PDN which was observed during Hallpike maneuver to either side and during central head hanging. During Hallpike maneuver, the PDN was more prominent when the involved ear was lowermost. CONCLUSION : These transitions suggest that AC-BPV may involve the uppermost or lowermost ear during Hallpike maneuver. In patients with AC-BPV, the direction of torsional nystagmus may play a crucial role in deciding the affected ear during Hallpike maneuver.

OBJECTIVES: To estimate mumps incidence during the study period and to evaluate the completeness of case reporting. METHODS: Capture-recapture methods, originally developed for counting wildlife animals, were used. The data sources were 1) the National Notifiable Communicable Disease Reporting System (NNCDRS; 848 cases), 2) the School Health Reporting System, temporarily administered by the Division of Education (SHRS; 1,026 cases), and 3) a survey of students (785 cases). We estimated the number of unobserved mumps cases by matching the three data sources and fitting loglinear models to the data. We then determined the estimated total number of mumps cases by adding this to the number of observed cases. Completeness was defined as the proportion of observed cases from each source to the total of estimated cases. RESULTS: The total number of observed cases was 1,844 and the total number of estimated cases was 1,935 (95% CI: 1,878-2,070). The overall completeness was 43.8% of the NNCDRS, 53.0% of the SHRS, and 40.6% of the survey. However, completeness varied by area and age. CONCLUSION: Although the completeness of NNCDRS data appeared higher than in the past, it is difficult to generalize this result. In Korea, it is possible to estimate the size of health hazards relatively cheaply and quickly, by applying capture-recapture methods to various data using a multiple data collection system.
