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.

PURPOSE: Efficacy of the new rotavirus vaccines (Rotarix(R), RotaTeq(R)) recently developed can be affected by the rotavirus genotypes prevalent in communities. We performed this study to identify the recent distribution of rotavirus genotypes prevalent in Jeju. METHODS: Genotyping of human rotaviruses was performed using 81 samples collected from 154 inpatients and outpatients with rotavirus gastroenteritis at Cheju National University Hospital between July 2005 and June 2006. All six (1, 2, 3, 4, 8, 9) G serotypes were identified by amplification of segments of the gene for VP7 using the reverse transcription-polymerase reaction (RT- PCR). RESULTS: The results of RT-PCR for 81 samples were all positive. G typing of the VP7 protein showed that G1 was the most dominant circulating genotype (65.5%) followed by G2 (14.8%), G3 (13.6%), G8 (1.2%), G9 (1.2%), G4 (0%), and a combination of G1/G3 (3.7%). CONCLUSION: This distribution of rotavirus VP7 genotypes in Jeju is different from that in other domestic areas; the most dominant circulating genotype was G1.

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

The aim of this study was to reveal the current status of forensic practice in Cheju province. Data used for this study was based on both autopsy reports and records of postmortem inspection with brief history derived from criminal divisions of all of three police agencies in Cheju. The range of subjects was limited to unusual deaths occurring in Cheju province during the year of 1997. Traffic accidents were excluded in this in Cheju province during the year of 1997. Traffic accidents were excluded in this category. All subjects were reviewed with respect to age, sex, cause of death and manner of death. The results were as follows; 1. The total number of unusual deaths was 220, of these 170 cases(77.3%) were males and 50(22.7%) were females. 2. In age distribution, the age group of 40-49 occupied the highest proportion(25.9%). 3. According to the manner of death, the cases of violent deaths were 175(79.5%), natural deaths;33(15.0%), and unknown cases ;12(5.5%). 4. For the violent deaths, the percentage of accidental death was 50.9 and suicide;32.0, homicide;5.1, undetermined cases;12.0. 5. According to the cause of death, asphyxia was the most common (101cases, 45.9% of the unusual death), followed by injury(18.2%) and disease(15%). 6. Among 101 deaths of asphyxia, 61(60.4%) were deaths due to drowning. 7. The total number of autopsy was 56 (25.5% of total unusual death). 8. Twelve cases(5.5%) remained as deaths of unknown cause and unknown manner without further postmortem examination.

This study was conducted for the purpose of obtaining basic information on the patterns of medical care expenditures, and identifying some determinants of medical care expenditures in the rural Korea. Nine guns were chosen from the eight porvinces, excluding Cheju island. One gun in each province and two villages were selected from the each myon or ub within the selected guns. The total number of households was 1,789 and the sample size was 9,826 non-institutionalized people. Followings are the major findings of the study. 1) Medical care expenditures increase proportionally with age in terms of cost per patient, per episode of illness, per treated case, and per person. Averagely, it cost 2,756 won per patient, 2,614 won per spell of illness, 4,361 won per treated case, and 413 won per person. 2) Medical care expenditures increase proportionally with educational level of patients. College graduates spent the most, 4,726 won per patient, 5,987 won per treated case, and 670 won per person. 3) The male spent a little more than the female in terms of per patient, per episode, and per person. For example, a male spent 23 won more than a female. 4) Those who were suffering from illnesses longer than 1 year spent three times mort than that had illnesses of less than 1 year duration. 5) The simple correlation coefficient between activity restriction and medical care expenditures was the highest among others, 0.491. The next was 0.294 between duration of illness and medical care expenditures. 6) Attempts are made to identify the explanatory variables in medical care expenditures. Thirty one per cent of the variances in the expenditures can be accounted for by the selected 15 predictors. Those predictors belonged to clinical conditions, such as activity restriction, duration of illness, and nature of conditions, are proved to be the most potent independent variables. Level of education and monthly family income are also significant in terms of beta coefficient. Further studies are called for to unreveal the determinants of medical expenditures.
