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.

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.

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 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.

INTRODUCTION: Recent investigations have demonstrated that citrus red mite is a common sensitizing allergen in children and adults living in rural areas of Cheju island. OBJECTIVE: The aims of this study were to evaluate the sensitization rate to the citrus red mite and to determine the risk factors for this sensitization in adolescents living in rural areas of Cheju island. SUBJECTS AND METHODS: A total of 3,395 adolescents (from ages 13 to 15 years old) living in rural areas of Cheju island were enrolled in this study. Each subject was evaluated by a modified ISAAC questionnaire, and a skin prick test with 11 common inhalant allergens including citrus red mite. RESULTS: On skin prick test the most common sensitizing allergen was D. pteronyssinus (27.9%), followed by D. farinae (23.9%), citrus red mite (18.3%), and cockroach (16.7%). Sensitization rate to citrus red mite was higher in those living near citrus orchards than in those living far from the orchards, and higher in those visiting citrus orchards more frequently than in those visiting less frequently. CONCLUSION: Citrus red mite is a common sensitizing allergen in adolescents living in rural areas of Cheju island. The sensitization rate to citrus red mite may be partially determined by environ- mental exposure.

A study was done to evaluate the diagnostic value of ultrasonography on acute scrotum patients. During the last three years, 25 patients were managed at Cheju Medical Center, eight of them were testicular torsion patients including one cryptorchid testicular torsion. one torsion of appendix testis, 11 acute epididymitis and 5 testicular rupture due to blunt scrotal trauma. Ultrasonography revealed enlarged testis and epididymis in all of the 8 testicular torsion patients and 7 of them showed inhomogeneously decreased echogenecity of the testis and epididymis. All acute epididymitis patients showed enlargement of the epididymis, and inhomogeneously decreased echogenecity was found in 8 of them. But testicular echogenecity was normal in all of the acute epididymitis patients and enlargement of the testis was found in two. All of the 5 testicular rupture patients showed irregular hypoechoic portions in the testicle and distorted testicular morphology, and linear fracture lines of the testis were found in two. We could suggest that scrotal ultrasonography is useful for the early differential diagnosis of the acute scrotum, especially when scrotal radioisotope scan is not available.
