With the development of the aviation industry in Korea, the number of aircrafts has increased every year. About 10 flight departments have been established at domestic universities, and flight training is conducted until the course of commercial pilot certificate. In addition, private aviation institutes using Muan airport as a base have also increased, and the number of training aircrafts in the eastern and western regions of Jeonnam region has increased dramatically. Along with an increase in the number of training aircrafts, aviation accidents have also increased. From April 2018 to September 2019, 11 accidents occurred at Muan airport and Yeosu airport. This study aims to develop a pre-flight safety protocol to promote flight training safety. Three aspects-including technical factors, human factors, and organizational factors-were considered in this study.

This study was to investigate dietary habit for residents in the rural area of Chonnam, Muan. The subjects were composed of $61.2\%$ male and $38.3\%$ female (510 adults). In regularity of meal time, $56.3\%$ of the subjects had meals regularly. The older people were significantly higher than the younger people at regular intervals of meal times (p < 0.0001) . The majority of the subjects had appropriate meal amounts. $73.5\%$ of the subjects had balanced diets. Unbalanced diet was higher in younger people than in older people. The highest frequency to dining out was once a month and the lower age was significantly higher than older age (p < 0.001) When dining-out, the most important criteria for selecting a meal was the taste of food. $62.4\%$ of the subjects ate meat and greasy animal food more than once a week. The younger in age and higher in educational levels have increased meat intake frequency. In the eating methods of animal fat, $37.5\%$ of the subjects were high by eating generally untouched. The older in age, lower in education level have more increased animal fat intake frequency. $60.7\%$ of the subjects took snacks. The kinds of snacks were fruits, coffee, alcoholic drinks, candies and confectioneries, drinkables and tea, milk and dairy products, in order. Consequently, nutrition education is for them with special emphasis on regularity of meal times, unbalanced diets, dining-out and snacks to the younger people, whereas it is the necessary eating methods of animal fat and snacks to the older people.

The purpose of this study was to investigate the anthropometric variables, dietary behaviors, nutrient intakes and distribution of serum lipid levels for Muan-gun inhabitants. The subjects was consisted of 212 men and 317 women. There were significant differences in the height, weight, BMI and fat mass with ages. In the onion intake status. 90.6(79.9)% of men(women) liked. 56.8(46.4)% of men(women) intakes 3 times per day, 29.6(40.8)% of men(women) 50g per one time and 83.1(87.5)% of men (women) after cooking. The mean energy intake of the subjects were 2,043㎉ for men and 2,105㎉ for women. Men (women) consumed 88(90)g protein. 34(38)g lipid, 340(355)g carbohydrate, 10.5(11.7)g fiber, 655(757)mg calcium. 1,396(1,421) mg phosphorous. 14.7(15.9)mg iron. 7.061(7,244)mg sodium, 3.597(3,704)mg potassium, 1.983(1,369)RE retinol, 1.4(1.5)mg thiamin. 1.1(1.4)mg riboflavin. 19.4(20.4)NE niacin. 172(160)mg ascorbic acid and 232(239) mg cholesterol. respectively. The level of triglyceride(TG) was 136.0(114.2)mg/dl, total cholesterol(TC) was 179.1(174.9)mg/dl HDL-C was 43.3(43.3)mg/dl, LDL-C was 109.6(107.9)mg/dl. VLDL-C was 26.8(22.8)mg/dl and AI was 3.2(3.0) And 68.1(79.0)% of men(women) were assessed as Normocholesteroiemia(NC) and 66.2(69.9)% of men(women) as Normotriglyceridemia (NTG). Most of the subjects in Muan-gun preferred and ate onions routinely and had normal range of serum cholesterol and triglyceride level. Therefore it is suggested that intake of onions is effective for decreasing the serum cholesterol and TG levels.

We investigated seasonal changes in the mesozooplankton community structure in November 2006 and February, May, and August 2007 at 12 stations in the semi-enclosed Muan Bay, Korea. Forty taxa were sampled, with an average abundance ranging from 1,459 to 20,078 indiv. $m^{-3}$; the highest abundance was detected in August 2007, and the lowest in February 2007. Acartia omorii, A. hudsonica, A. ohtsukai, Bestiolina coreana, Calanopia sp., Paracalanus parvus s. l., Cirripedia larvae, Decapoda larvae, and Gastropoda larvae were the most abundant taxa detected. The species diversity of the mesozooplankton was high around the inner regions in August 2007 but it was relatively low in November 2006. Non-metric multidimensional scaling (nMDS) revealed significant differences in the structure of mesozooplankton community among the seasons. Canonical correspondence analysis (CCA), performed to examine the relationships among dominant taxa, stations, and environmental variables, showed that most species of copepods were positively correlated with temperature, salinity, chlorophyll a, and COD concentration. Our results suggested that the mesozooplankton community structure observed in this study might be affected partly by the seasonal changes in environmental variables, such as the status of the sluice gates (i.e., open or closed) and the in situ production of resting eggs by major copepods.

Genomic DNA from the muscle of marsh clam (Corbicula leana) from Gochang, Muan and a Chinese site was extracted to identify genetic differences and similarity by randomly amplified polymorphic DNAs-polymerase chain reaction (RAPD- PCR). Out of 20 primers, seven primers produced amplified fragments which were consistently polymorphic. A total of 1,246 amplified products were produced of which 530 were polymorphic $(42.5\%)$. The number of polymorphic bands produced per primer varied from 40 to 122 with an average of 75.7 in marsh clam from Gochang. 3.28 of the 23.0 polymorphic bands per lane were found to be polymorphic. Also, about $4.34\%$ of total polymorphic bands were specific to marsh clam from Gochang. The major common bands of 0.28 kb generated by primer OPB-15 (GGAGGGTGTT) were present in every individuals, which were polymorphic. This common bands in every individuals should be diagnostic of specific strains, species and/or their relatedness. Primer OPB-19 (ACCCCCGAAG) produced the highest number of 12 specific bands. The intra-population variation was revealed in the band patterns identified by this primer. The random primer OPB-12 (CCTTGACGCA) yielded the amplified fragments which were consistently polymorphic between the marsh clams from Gochang and from Muan. This primer produced a total of 77 polymorphic bands: 31 bands from Gochang, 14 from Muan and 32 from the Chinese populations. An average of polymorphic bands were 1.8 from Gochang and 2.5 from the Chinese populations. This value obtained from the Chinese population was higher than those from the two domestic populations. Generally, the RAPD polymorphism generated by these primers may be useful as a genetic marker for strain or population identification of marsh clam.

Korea government has established 67 agri-food clusters for 10 years. In recent years, the criticism of this policy has significantly increased due to trials and errors. The purpose of this study is to suggest some policy implications for the focal firm and governance mechanism through the case study of Muan Loess Sweet Potato Cluster. The concept of netchain was used as an analysis framework. Muan Loess Sweet Potato Cluster doesn't operate an integrated production organization and focal firm doesn't exercise its influence as well. The cluster agency, focal firm of Cluster, is important for a Agri-food Cluster to grow continuously. it must have a great influence on organizing networks and an enough capacity for forming coordination mechanism. Also, Local governments must actively be involved in the network formation and coordination and inform the vision and plan for development.

The Piseo-ri site in Muan provides significant data in investigation on the Paleolithic sites in the southwest coast of Korea. Stratigraphic and geological analysis indicates that the characteristic of soil wedge can vary in accordance with soil property and relief of paleo-surface. Considering that the cultural layer was deposited after the Last Glacial Maximum, co-occurrence of the late Middle to early Upper Paleolithic stone tools suggests a possibility of redeposition of different ages resulted from active erosion. The result shows that the distribution of the Paleolithic tools and the property of soil wedge could be controlled by environmental conditions such as relief of paleo-surface and climate.

As the demand for environmental-friendly agricultural products continues to rise due to increased concerns regarding food safety and ecosystem conservation, it is becoming important to identify regions and spatial locations where environmental-friendly should be intensively established for production integration. This study aims to analyze the spatial distribution of environmental-friendly certified farms in Jeollanam-do, South Korea. Spatial statistical analysis based on Local Moran's I and Getis-Ord Gi^* were used to identify spatial cluster characteristics and landscape indices were utilized to analyze spatial patterns of environmental-friendly certified farms. The results indicated that Haenam-gun, Gangjin-gun, Muan-gun, and Jindo-gun were identified as hotspots, while Muan-gun, Goheung-gun, and Jindo-gun exhibited high connectivity. This suggests that environmental-friendly certified farms in Muan-gun and Jindo-gun were clustered and closely connected to one another. Based on the results of the spatial distribution of environmental-friendly certified farms, areas belonging to the hotspot and with high connectivity should be managed as clustered districts to secure the foundation and system of environmental-friendly certified farms. Areas that belong to cold spots and have low connectivity should be preceded by measures to promote conversion to environmental-friendly agriculture. In addition, it is necessary to make it possible to create a large-scale cluster district through a long-term spatial planning strategy to expand the environmental-friendly certified farms. The findings of this study can provide quantitative data on policies and discussions for developing a model for rural spatial planning.

Tidal asymmetry would occur owing to shallow water tides at the Western Coast of macro tidal area. Especially, as ebb dominance of Mokpo coastal zone is known as the most prominent in Korea, it had been studied by domestic researchers. The cause of ebb dominance in Mokpo area is considered due to extensive inter-tidal zone in Muan Bay, and this has been studied based on amplification ratio, relative phase and skewness of tide/tidal flow curves in order to analyze qualitative tidal asymmetry. Furthermore, it was possible to figure out tidal characteristics with the difference of tidal amplitude and phase with Mokpo Harbor by observing the tide for 15 days in Muan Bay, which showed 40 minutes shorter ebbing time than at Mokpo Harbor. In addition, tidal flow prediction data in Mokpo North Harbor and Mokpo-Gu were analyzed. Meanwhile, the basis regarding qualitative interpretation of bed sediment and suspended sediment was provided by examining the qualitative changes in tidal asymmetry for spring-neap tidal cycle through the PCA/SWA indices. In addition, by examining long-term changes of ebb dominance in Mokpo Port, tidal characteristics of the past, present and future in this area, which is related to tidal asymmetry, is also provided.

To understand the variation and transport pattern of suspended matters, salinity, tidal current and suspended matters in semiclosed Muan Bay have been monitored during winter and summer. The suspended matters show considerably seasonal variations with low concentration and homogeneity in the water column during winter season, but with high concentration and layering during summer season. Particularly, during summer season, the freshwater and the suspended matters influxed by the gate operation of the Youngsan River sea-dike are transported northward in accordance with the would flow into the inner-bay by relaxed flood currents after the construction of sea-dike and sea-walls in the Mokpo coastal zone. But, in the south bay-mouth, those matters outflow through the bay-mouth, resulting from tidal ebb dominance and asymmetry in the west bay-mouth. The residual suspended matter flux is much higher in the south bay-mouth(-0.0955kg/m ${\cdot}$ sec) than that of west bay-mouth(0.0078kg1m ${\cdot}$ sec). Accordingly, The Muan Bay is interpreted as erosion-dominated environments, and the erosion somewhat progresses in the intertidal flat of the bay.
