Objectives: The purpose of the study was to investigate the subjective oral health status, oral health promotion behaviors, and related factors in the university students in Jeonnam. Methods: A self-reported survey was completed by 480 university students in Jeonnam from June 1 to 15, 2016 based on convenience sampling. The questionnaires consisted of general characteristics of the subjects, subjective oral health status, and oral health promotion behaviors. The collected data were analyzed by frequency analysis, independent t-test, one-way ANOVA and multiple regression analysis among others. Results: The average of subjective oral health status was 3.36 and the oral health promotion behavior was 2.87. It was shown to have influence upon the oral health promotion behaviors in the more the use of oral care products, in the better the oral health condition, in the more dental visit experience, in the more you do not drink, and in the more experience in oral health education. Conclusions: To improve the oral health in the university students, interest, knowledge, attitudes, and behavior in the oral health should be changed through development of oral health education programs. Also, efforts to develop curriculum and establish the university policies will be necessary so as for the university students to have responsibility for general health care including oral health in the universities.

Studies on the relative abundance of potential vectors of scrub typhus was conducted from April to October 2009 at the Jangseong of Jeonnam Province, Korea. Among the total 62 field rodents collected by the Sherman collapsible traps, 56 rodents were $Apodemus$ $agrarius$ (90.3%), 4 were $Crocidura$ $lasiura$ (6.4%) and 2 were $Cricetulus$ $triton$ $nester$ (3.2%). Out of the 62 field rodents, 39 were parasitized by chiggers, showing 62.9% of the infestation rate and 80.0 of the chigger index. Chigger index of $A.$ $agrarius$ and $C.$ $triton$ $nester$ were 79.9, 82.0, respectively. But chigger mite was not collected from $C.$ $lasiura$. From the trapped field rodents, 3,120 chiggers were collected and identified with 6 species of 2 genera. $Leptotrombidium$ $scutellare$, the vector species of tsutsugamushi disease, was the dominant species, showing 2,276 chiggers (72.9%). $L.$ $pallidum$ was the second dominant species showing 346 chiggers (11.0%). The distribution of chigger mites was showed the different dominant species according to seasons. $L.$ $pallidum$ was the predominant chigger collected in April (34.8%), May (77.8%) and Jun (39.3%), whereas $L.$ $scutellare$ was the predominant chigger collected in September (78.78%) and October (76.8%).

With the globalized coming of the knowledge-based society following the post-industrial period, both the crises and opportunities have been occurring together as non-special affairs, which is the same situation in Rural Korea. A crucial key for maximization of potentialities of emerging opportunities is to mobilize the multi-valuedness embedded in rural areas as one of new growth powers. In order to realize a variety of multi-valuedness of rurality, it should be needed to re-discover and re-evaluate rural resources by paradigm shift and to identify the multi-valuedness of resources systematically and scientifically. On the basis of this understanding, this study aimed at setting up the evaluation indicators system by rural village types to identify systematically the multi-valuedness embedded in rural villages in the initial step. Integrated evaluation indicators system was made with 4-level hierarchies; high-leveled one with 3 fields(society, environment, regional economy); middle-leveled one with 8 areas; lower-leveled one with 19 sub-areas; detailed indicators totally with 39 items. These indicators were divided into 12 basic indicators applied to all types and 27 specialized indicators determining the characteristics of village types.

This research is based on a visitor survey at Jogyesan Provincial Park in Jeonnam, and its implications for interpretive planning. The research population was the set of weekend and holiday visitors, 20 years of age and older, to Jogyesan Provincial Park in Jeonnam, during the summer of 2003. A questionnaire was offered to every tenth person entering the park on every other weekend day and both holidays (June 1 and September 30). It was obvious that the interpretive program at Jogyesan Provincial Park, to meet the expectations of its visitors, should provide: (1) visitors with opportunities to experience the out-of-doors and learn about the cultural, historical and natural surroundings; (2) opportunities for the visitors to relax and escape from the normal and work environment; and (3) opportunities for the visitors to experience an atmosphere which enables them to achieve and self-actualize. In the area of interpretive programs, expectations are usually priorities, except for mountain climbing and exercise. Enhancing achievement and self-actualization is rarely a consideration and needs more emphasis in the future interpretive programs and plans.

A severe root rot of kiwifruit caused by a species of Phytophthora occurred in 1-to 5-year-old vines at the south coast region of Korea in 1997. Infected vines exhibited leaf chlorosis, scorch and defoliation, root and stem rot, and eventual death. The disease was relatively severe in poorly drained lowlands, of which 19 out of 23 fields were damaged by the disease. Meanwhile, only one among 58 upland fields was infected by the disease. Incidence of infected vines reached over 80% in heavily damaged fields and a species of Phytophthora was isolated from inner tissues of roots, stems, and rhizosphere soils of the plants. The causal pathogen was identified as P. drechsleri based on its mycological characteristics. Pathogenicity of the fungus was confirmed by artificial inoculation to seedlings of kiwifruit 'Hayward'. The pathogen was re-isolated from the inoculated plants showing symptoms similar to those observed in the fields. Root rot of kiwifruit caused by P. drechsleri has not been reported previously in Korea.

Although stable and safe drinking water supply to the customers is a basic function of multi-regional water supply systems in Korea, most systems have their vulnerabilities in emergency time due to the branch-type. Application of connections from the other water supply system can provide a solutions for these tentative problems. This paper describes reduction planning of water supply accidents that can minimize a service interruption to customers in multi-regional water supply system by connecting pipe lines between local water supply systems in Mokpo city areas. The result of this study shows that Juam dam multi-regional water supply systems can cover all of the water shortage in southern parts of Jeonnam multi-regional water supply systems by transmitting water through connected pipes between local networks. This can be effective to supply water interactively in various contingencies, when a pipe line accident occurs in southern area of Jeonnam multi-regional water supply systems. On the contrary, southern area of Jeonnam multi-regional water supply systems can cover 99.5 %($62,500m^3/day$) of the water shortage of Juam dam multi-regional water supply systems when service interruptions caused by various pipe accidents occur in the system.

By the continued island-mainland bridging works, increased consumer demand for seashore regions and fundamental improvement of accessibility to metropolitan areas, rural service industries in the island areas has been rapidly developed in the past decades, and also, their functions differentiated geographically. In most island areas, catering and accommodation sectors have been expanded, while traditional trading sector decreasing. And the dominant power of public sectors has been increased but private ones decreased. So, the overall development trends of service industries in island areas would be considered as unhealthy for rural economic sustainability. As a tentative solution, it may be proposed that through the functional specialization/differentiation and efficient linking/networking of rural service industries with multifunctionality of countryside capitals, their spatial cohesion would be strengthened.

The fauna and the distribution of plant parasitic namatodes were investigated by smapling about five hundred grams of soil around roots of mulberry trees from 929 mulberry fields in Korea. Of fourteen genera detected on mulberry fields, Paratylenchus aciculus, P. projectus, P. morius, Helicotylenchus dihystera, Meloidogyne arenaria were found to be parasitic to mulberry. Among them Paratylenchus species were the most abundant in mulberry fields, but Tylenchorhynchus sp., Aphelenchus sp., Helicotylenchus sp., and Meloidogyne sp. were also observed in high frequency. Meloidogyne species were observed in high frequency in Jeonbuk, Gyeonggi and Jeonnam, Helicotylenchus sp., in Gyeongnam and Gyeonggi, Xiphinema sp., in Jeonbuk and Jeonnam, and Paratylenchus sp., in Gyeonggi, Gyeongbuk, Gyeongnam, and Jeonnam. The growth of mulberry was poor as the increase of density of Paratylenchus sp.

The purpose of this study was to examine the difference of the father's and mother's reactions to their children's negative emotions, relations among the children's variables, parent's variables, and parent's reactions. The subjects selected were 183 mothers and 183 fathers with children aged three to five-years-old, from a childcare center and kindergarten in Kwang-ju. Parental emotion-related practices regarding children's negative emotions were assessed with an adaptation of the CCNES(Fabes et al, 1990) that was modified by Kim Hee-Jung(1994). Descriptives, Pearson's correlation coefficient, were used for data analysis by using the SPSS 15.0 program. The results of this study can be summarized as follows: First, fathers and mothers used more positive reactions than negative reactions when their children showed negative emotions. The mothers were significantly higher than fathers on encouragement of expression, punitive, and distress reactions. Second, the children's age and gender, parent's age, level of education and income were negatively and positively correlated to the father's and mother's reactions to their children's negative emotions.

Hepatitis A virus (HAV) is a causative agent of triggering acute hepatitis which is transmitted by person-to-person contact and or fecal-oral route. In previous studies, most hepatitis A virus (HAV) isolates had been genotype IA in Korea. Recently, a small number of different genotypes were reported with an upsurge of acute hepatitis by HAV. Therefore, the distribution of HAV genotypes was investigated. RNA was extracted from anti-HAV IgM positive sera which were collected from February to August 2009, at a tertiary care hospital in eastern Jeonnam, Korea. Nested reverse transcription PCR and direct sequencing for VP1/P2A region of the HAV were performed. A total of 365 cases with suspected acute hepatitis were tested for anti-HAV IgM and positive results were obtained in 24 sera (9.0%), which were collected 2 to 15 days (median, 7 days) after the onset of symptoms. Of the 24 seropositive samples, 14 (58.3%) samples were positive for HAV RNA, among which 4 isolates (28.6%) were genotype IA and the other 10 (71.4%) were genotype IIIA. Both IA and IIIA genotypes were isolated from 5~6 neighboring administrative districts throughout the year without geographic or seasonal restrictions. HAV genotypes (IA and IIIA) were observed from the eastern Jeonnam for the studied.
