The island areas have disadvantageous conditions compared to inland areas due to the characteristics which are separated, surrounded by seas, isolated. However, as the problems with separation that ultimately caused regional underdevelopment in island areas have been eased by the artificial works linking an island to land and the societal perspective on littoral districts has changed from productive view to consumptive view, the population trend in the island areas has been differentiated according to the regional conditions. But it is the reality that the population trend in the island areas has almost never been analyzed. In this regard, this study tried to analyze the overall demographic transition in eup/myon-level island areas and provide the basic data to establish flexibly and accurately regional development policies for island areas in rural As a result, as the regional conditions of island areas become more various, the potential and conditions of development have been differentiated and these trends will be more intensified. In response, the regional development policies for island areas in rural have to be reorganized actively.

This study aimed to estimate control thresholds for managing common cutworm, Spodoptera litura Faricius (Lepidoptera: Noctuidae) at different larval densities and growth stages of Chinese cabbage in field conditions. The percent yield reduction (Y) of Chinese cabbage infested by different densities of S. litura (X, no. of larvae/100 plants) for three weeks were estimated by Y=-21.85X+1300 (R2=0.997) 5 days after transplanting and Y=-12.1X+1382 (R2=0.998) 20 days after transplanting. Based on the relationships between the densities of S. litura larvae and the yield index of chinese cabbage, the number of larvae (2nd to 3rd instar) which caused 5% loss of yield was estimated as 2.9/100 plants 5 days after transplanting, and 5.6/100 plants 20 days after transplanting.

After getting through the financial crisis, Korean government has promoted Local Industry Promotion Project across the country by realizing the needs to overcome structural recession and promote self-growth. Therefore researching current manpower status and manpower demand in shipbuilding industry, which is the strategic industry of Jeonnam province, is very critical to enhance the competitiveness and efficiently manage training professional manpower. In this respect, this study mentioned some issues and provided the improvements for the research on demand for Professional manpower training project in Shipbuilding industry of Jeonnam province. It was shown that the aging trend of professional workforce, short in skilled/professional manpower and lack of education & training institutions are critical problems of shipbuilding industry in Jeonnam province. To improve these problems, various support policies such as strengthening networks among related agencies and companies or universities are strongly recommended.

The purpose of this study is to construct a regional-sector-fishery-offshore and inshore fishery competitiveness index, examine the types and changes of competitiveness, and derive implications by processing data of the Survey on the Current Status of Offshore and Inshore Fishery from 2013 to 2020 for this study. The main results of this study can be summarized as follows. First, considering the competitiveness of offshore and inshore fishery by region and year, Jeonnam, Jeju, and Incheon were relatively competitive. Second, considering the competitiveness of inshore fishery by region and year, we found that Jeonnam, Chungnam, Jeonbuk, and Jeju were relatively competitive. Third, looking at the types of competitiveness based on the competitiveness index in the management sector of offshore and inshore fisheries by region and year, Ulsan, Jeonnam, and Gyeongbuk were relatively competitive between 2014 and 2020. Fourth, Jeonnam and Jeju were relatively competitive between 2014 and 2020 based on the competitiveness index in the fishing sector of offshore and inshore fisheries by region and year. Fifth, we found that Jeonnam, Jeju, and Chungnam were relatively strong in the competitiveness of offshore and inshore fishery, combining the offshore and inshore fishery indexes by region and year. The results of this study have some limitation on outlier treatment, grade assignment, and weight for aggregation, so research considering these needs to be done in the future. In conclusion, the results of this study which were derived objectively and scientifically in the era of the 4th industrial revolution, when evidence-based decision-making was becoming critical, are expected to help the central or local governments determine the priority of support projects or investments.

The purposes of this study were to compare price sensitivity analysis for using environmental-friendly agricultural products in university foodservice between Jeonnam and Gyeongnam areas in Korea and to suggest the optimum guideline for price increase. The questionnaires were distributed to 600 university students respectively in Jeonnam and Gyeongnam area from July 15 to July 25, 2008; among them, 570 students from Jeonnam area and 490 students from Gyeongnam area responded. The results of this study were as follows. First, Indifference price (IDP) were 890 won (Jeonnam area) and 1,050 won (Gyeongnam area); Optimum price point (OPP) were 1,030 won (Jeonnam area) and 1450 won (Gyeongnam area). Price stress range were 140 won (890~1030 won) in Jeonnam area and 400 won (1050~1450 won) in Gyeongnam area. Second, point of marginal cheapness (PMC) were 500 won (Jeonnam area) and 790 won (Gyeongnam area) whereas point of marginal expensiveness (PME) were 1,170 won (Jeonnam area) and 1820 won (Gyeongnam area). Range of acceptable price (RAP) were 670 won (500~1170 won) in Jeonnam area and 1030 won (790~1820 won) in Gyeongnam area. Third, on the basis of IDP percentage and RAP, students in Jeonnam area were more sensitive to meal price increase than students in Gyeongnam area. In contrast, on the basis of Price Stress, students in Gyeongnam area were more sensitive to meal price increase than students in Jeonnam area. Hence, when using environmental-friendly agricultural products in university foodservice, in Jeonnam area, meal price increase should be recommended to be in RAP (500~1170 won), and in Gyeongnam area, meal price increase should be recommended to be in RAP (790~1820 won).

Remote Control System based on Sproute Cultivator using LED characteristics was realized. It was carried out to investigate into the effect of LED Control with the physiological activity of sprouts. We have also composed a Combined Automatic Control System possible for the control of temperature and humidity at the same time. The applied LEDs for measurement are blue, green, red, white, yellow leds. And we producted the remote control OS using Linux and defined the characteristics of automatic control about sprouts.

With the development of national economy and increase of income, consumers' demand for quality and safe agricultural products have increased and perception on environmental-friendly Farming products has been sharply changing. In other words, consumers increasingly show the tendency to prefer environmental-friendly farming products for considering health and environment protection, despite higher price. The environmental-friendly farming products in Jeonnam Province is still at its early stage, accounting for 1% or so of the total products. Considerable part of environment-friendly farming products, nevertheless, difficult problem to End consumers, thus sold at relatively high prices. To the questionnaire asking their most severe difficulty is about 30.5% for sale. This suggests that strategies for consumption expansion of environment-friendly farming products, including of consumers, confidence, publicity of consumers, should be established to increase the income of environmental-friendly farmers in Jeonnam Province.

A total of 736 Holstein cows were examined for incidence of infertility and 57 infertile cows of them were examined for blood values. The results obtained were as follows: 1. Fifty eight heads (7.9%) of 736 Holstein cows examined were proved to be infertile and the causative disease of 58 infertile cows were diagnosed as silent heat (31.0%), repeat breeder (20.8%), dysfunction of ovary (15.5%), lutein cyst (13.8%), endometritis (8.6%), follicular cyst (5.2%), cervicitis (1.7%), pyometra (1.7%), and free-martin (1.7%). 2. Among the data of blood values of 57 infertile cows, values of total serum protein and serum calcium were remarkably lower (p 0.01) than those of normal cows. Meanwhile the unbalanced Ca/P ratio (1.1) was observed.
