This study was conducted to improve the quality of home-based cancer management programs through a survey of satisfaction and needs of the program provided by a regional cancer center. From March 2015 to October 2015, we conducted face to face surveys of patients and caregivers enrolled in home-based cancer management. A total of 101 patients, 59 patients and 41 caregivers, were enrolled. Breast cancer was the main cancer and 51 (86%) patients and 36 (85%) caregivers were satisfied with the number of visits for home-based cancer management. For the service application route, 22 patients (37.29%) obtained information through the cancer center publicity paper and 11 caregivers (26.19%) received recommendations from acquaintances. Except for treatment provided directly to the patients, psychological counseling was the most preferred, and satisfaction regarding picnic and cancer education were also high. Satisfaction with the program provided by regional cancer center was relatively high ($4.14{\pm}1.21$ on a 5-point scale). Additionally, satisfaction of the patients was higher than that of the caregivers, but this difference was not significant ($4.29{\pm}1.11$, $3.93{\pm}1.31$, p = 0.141). Self-esteem was higher among caregivers than patients, but this difference was not significant. To improve the quality of life of cancer patients and caregivers, it is necessary to develop customized programs considering patients' economic situations and need for psychological counseling.

A leafhopper, Zorka sp. was collected from a persimmon (Diospyrosi kaki, cv SangjuDungsi) orchard in Sangju, Gyeongsangbuk-do, Korea on 15 June, 2008. This leafhopper gave a serious damage to persimmon leaves, being a new pest to persimmon. This leafhopper was tentatively identified as Zorka sp., which has not been recorded in the science. White spots of <1mm-circle occurred around the vein of damaged leaves. Most part of leaf was turned to white when heavy infection occurred. The first symptom occurred from 4 days after introduction of Zorka sp. (4 adults/persimmon leaf). We investigated the occurrence of Zorka sp. in the persimmon orchards in Korea from 2008 to 2009. Total 143 orchards from 11 cities in 6 provinces were observed from July to August. The damage caused by Zorka sp. was found in 22 orchards (15.4%) of the investigated. According to locality, 40.7% of orchards were damaged in Yeongdong, Chungcheongbuk-do and 33.3% in Wanju, Jeollabuk-do. However, no damage was observed from the orchards in Gyeongsangnam-do and Jeju-do, south part of Korea. Especially, 9 of 11 orchards in Youngdong were located close to grapevine yards.

The flying fish, Prognichthys agoo, is widely distributed in the coastal waters of south-eastern Korea. On July 14, 1986, mature adults of flying fish were captured from U-do, Cheju-do. The eggs were stripped and fertilized by the wet method on the ship. The mature eggs are demersal and adhesive with 30-40 filaments. The egg diameter varied from 1.42 to 1.58 mm. The water temperature throughout incubation ranged from 23.70 to $27.82^{\circ}C$, and salinity was maintained at $30.75-33.76\%_{\circ}$. The hatching took place in 174 hours after fertilization. The newly hatched larvae measured 4.75-5.25 mm in total length possessing yolk sac and about 45-46 myotomes. The larvae cultured for ten days after hatching reached 11.45-12.60 mm in total length and entered the juvenile period of life. Twenty days after hatching, the juveniles measured 20.01 mm in mean total length, and the scales were formed behind the pectoral fin.

The Chinese red-headed centipede Scolopendra subspinipes mutilans, a member of the arthropod class Chilopoda, is a traditional medicine used for the treatment of several allergic diseases, such as atopy. S. subspinipes mutilans samples were collected from different regions of South Korea: Sancheong, Gyeongnam; Yeonggwang, Jeonnam and Jeju-do. The nutritional values of the centipedes were analyzed to extend the species' applications. The crude protein and fat contents of all samples were high and ranged from 54.9-55.8% and from 26.8-30.6%, respectively. Essential amino acids were present; lysine was the most common and accounted for 3.4-3.6% of the essential amino acids. Glutamic acid, which assists in improving concentration, memory and other cognitive abilities, was the most common non-essential amino acid at 6.8-7.1%. It had a similar content percentage in all three regions' samples. Additionally, unsaturated fatty acids were present, and oleic acid, which prevents cancer and cardiac disease, was the most common at 41.3-48.6% of each sample. Mercury, a hazardous substance, was detected at a range of 0.08-0.11 mg/kg in all samples; the amount was lower than the standard food allowance. Additionally, no pathogenic microorganisms, such as Escherichia coli and Salmonella spp., were detected. There were no significant differences between the nutritional factors of the S. subspinipes mutilans samples from the three regions. Based on the nutritional analysis, Chinese red-headed centipedes have the potential to be food and medicinal ingredients due to their proteins, essential amino acids, unsaturated fatty acids and nutritive capacities.

This study was conducted to investigate the ovarian cycle changes of the mare according to the season. Twenty four Jeju crossbred horses(Thoroughbred ${\times}$ Jeju horse) raised in Subtropical Livestock Research Institute, National Institute of Animal Science, RDA were used to identify follicles and corpus luteum with ultrasonography once a week(May 2016~June 2017). Blood samples of experimental horses were collected twice a week for analysis of P4 hormone levels. The mares were considered to have resumed ovarian cyclicity on the day of ovulation if they followed by regular ovarian cycles. Only 13 cases(61.9%) of the total 21cases showed normal ovarian cycle, and 8 cases (38.1%) showed delayed ovarian cycle. Three cases(16.7%) in October, 5 cases(27.8%) in November and 5 cases(27.8%) in December(27.8%) ceased the heat and the remaining 5 cases(27.8%) showed that the estrus was maintained in winter. Horses that stopped estrus ceased the heat until March of next year, and 27.8% were continued the heat during non-breeding season. Eleven cases(61.1%) of 18 cases in April and 2 cases(11.1%) of 18 cases in May returned the estrus.

This study analyzed the experiences of victims of state violence, discovered differences between state violence and general trauma, and proposed ways to help heal trauma. Participants were composed of state violence victims and their families in total, including 11 from the Jeju 43 Incident, 11 from the Yeos u·Sunchoen 10.19 Incident and 6 form May 18th Democratic Uprising. As a result of using the grounded theory to analyze data, a total of 170 concepts, 57 subcategories, and 20 categories were derived. The central phenomenon was direct damage caused by state violence. This included 'post-traumatic stress', 'social stigma', 'isolation from community', 'socio-economical issues' and 'family dissolution'. As a result of the process analysis, the participants experienced six phases: 'trauma', 'isolation', 'resistance', 'resignation', 'recovery', and 'growth.' Each phase is sequential but at the time mutually affect each other. Based on the results, this study verified the difference between state violence and general trauma, and emphasized social and cultural factors, such as community support, were important factors in healing state violence trauma. Besides, the implications and limitations as well as suggestions for future research were mentioned.

We investigated the growth pattern of Red-tongued viper snakes (Gloydius ussuriensis), which were captured from the islet of the Jeju Island, Gapado between April, 2006 and November, 2009. The results indicated that there were some snakes that grew relatively fast, but most snakes either almost did not grow or grew around 10mm in snout-vent length during one year period. High growth rates was April and June. Since the growth rate of snakes is highly correlated with their foods, these results implied that the feeding activity of Red-tongued viper snakes is high during this period compared to other months. In female, difference in body condition between good-conditioned and bad-conditioned snakes became large as time elapsed from April to June. The body condition of the male Red-tongued viper snakes improved with the progression of time from April till June. Many of the Red-tongued viper snakes were captured between April and June, while they were rarely captured between July and September. Some of the Red-tongued viper snakes were captured during the autumn season. This tendency was because snakes were rarely active during hibernation and peak summer seasons. Thus, Red-tongued viper snakes are active between April and June and between September and November. They then go into hibernation as the temperature dropped in November. Furthermore, the limitation of the movement period of the Red-tongued viper snakes restricted their feeding activities while foods became scarce, which ultimately restricted their overall growth rate. The growth rate of the snakes decreased with age. The snout-vent length of the Red-tongued viper snakes and growth rate showed a negative correlation (r = -0.591), however, it was not statistically significant due to small sample size. The findings from this study could provide meaningful information in the further study of the life cycle of Red-tongued viper snakes.

Wild Mushrooms collected in Mt. Halla of Jeiu Island around altitude of $200{\sim}1000\;m$ from 1999 to 2000 were studied to investigate utilization as the natural breeding sites by wild drosophilids. Thirty-five mushroom species belonging to the 19 genera of 12 families from 2 orders were used as natural breeding sites by drosophilids. Adult flies emerged from 14 species of mushrooms belonging to the 11 genera of 8 families from 2 orders were identified. From the rest of 21 species of mushrooms, only larvae or/and pupae were reaped. Among 35 species of mushrooms, 34 species belonged to order Agaricales and only one species, Sarcodon scabrosum, belonged to order Aphyllophorales. In terms of composition of mushroom families, total 35 species belonging to 12 families were composed of 10 species of Russulaceae, 6 species of Amanitaceae, 4 species of each Tricholomataceae and Agaricaceae, 3 species of Boletaceae, 2 species of Strophariaceae and each one species of rest 6 families. Concerning the composition of the genus, 35 species belonging to 11 genera were composed of 8 species of Russula, 6 species of Amanita, 4 species of Agaricus, 2 species of Lactarius, and each one species of rest 7 genera. In terms of the mushroomsize preference of drosophilid flies for breeding sites, most flies preferred comparatively large mushrooms above 5 cm of pileus size in diameter, Fourteen species of drosophilids were identified as mushroom-breeding species. Among these, one and five species belonged to genera Mycodrosophila and Hirtodrosophila respectively, The genus Drosophila included the most abundant 8 species. Drosophila bizonata and Hirtodrosophila sexvittata bred on 6 species of mushrooms respectively, D. unispina bred on 3 species of mushrooms, rest species of Drosophila bred on one or two species of mushrooms. From the result of this study and other literatures, it could be presumed that much more mushroom species could serve as the natural breeding sites for greater number of drosophilid species than those examined in this study on Jeju Island.

This research investigated the reproduction cycle, litter size, and the effects of factors of red-tongue viper snake inhabiting in Jeju Island, to delve into their life strategy. Field survey was conducted in Jeju Island from May 2006 to November 2008. Reproduction cycle was analyzed through measurements of testis and follicle sizes in laboratory from March 2009 to December 2010. According to the research results, the sizes of red-tongue viper snake's testis and follicle clearly changed seasonally. The number of eggs within the oviduct were greater on the right side ($2.6{\pm}1.0$ eggs, n=16) than on the left side ($1.8{\pm}0.5$ eggs, n=16) (t=-2,721, p<0.05). Average (${\pm}SD$) of survival litter size (SLS) was $4.4{\pm}1.7$ (1~9, range), while total litter size (TLS) was $4.7{\pm}1.5$ (3~9, range), which were not statistically significant. However, their litter sizes were similar to the number of eggs within the oviduct (t=0.039, P>0.05). Relative litter mass (RCM) was $0.42{\pm}0.13$ (0.18~0.79, n=33), and tended to increase, as maternal condition of pre-parturition (MCPPI) was getting better. The sexual ratio of delivered litters showed no significant difference between male and female red-tongue viper snakes (♂:♀ = 1.15:1, n=73 ; ${\chi}^2$=0.342, P>0.5). Average neonate mass showed a weak correlation with maternal mass of pre-parturition (MMPP1) (r=0.387, P<0.05, n=33). Average neonate Snout-vent length (SVL) also demonstrated a weak correlations with maternal SVL (r=0.399, P<0.05, n=33) and MMPP1 (r=0.344, P<0.05, n=33). Average neonate mass and maternal SVL approached significant probability (r=0.323, P=0.067, n=33). This indicates that mother snakes can bear bigger litter due to its larger size. In some cases, litter's weight decreases as mother snakes are bearing more litter; however, the red-tongued viper snake did not show such exchange relationship. From this, it can be conjectured that a red-tongued viper snake has peculiarity of its own species. The research results are predicted to be used as the basis to find a life history of red-tongued viper snake.

The purpose of this study was to investigate the characteristics of species by comparing the external shape traits and skull size of Tscherskia triton in Jeju Island from May 2014 to November 2016. Body weight, head-body length, ear length, and hind-foot length were not statistically significant (p>0.05), but tail length was statistically significant in females compared to males (p=0.003). To examine the secondary sexual dimorphism characteristics of the collected T. triton, B_HR, T_HR, E_HR, and H_HR were calculated based on the head-body length, and only T_HR was statistically significant (p=0.003). Because of comparing male and female averages, among the 21 traits, the greatest length of skull (GLS; p=0.020) and occipitonasal length (ONL; p=0.014) were statistically significant and length of incisive foramen (LIF) was statistically significant, when the significance level was 90%. However, the other 18 traits did not show statistically significant differences between males and females (p>0.05). Other than GLS, ONL, interorbital breadth (IB), and breadth of occipital foramen (BOF), there was female-biased SSD. The results of this study are the analysis of external morphology and skull characteristics of T. triton in Jeju Island and will be used as basic data to understand the morphological characteristics of T. triton. In addition, the data can be used as a basic information to compare characteristics of T. triton, which is known as a single species, inhabited in China and Russia. The data will play an important role in biogeography and ecology research of T. triton, based on geographical conditions, climate effects, and habitat environment.
