        The purpose of this study is to estimate conservation value of fisheries resource protected area by the doublebounded dichotomous choice contingent valuation method. The data in this analysis come from a survey of respondents of resident in fisheries resource protected area using a proportional stratified sampling from the population. The questionnaires covered all the 5 fisheries resource protected area and the sample size of every protected area was 120 questionnaires. The survey period was from August to October in 2016. Above all, the average willingness to pay amount(WTP) per person of Namhae-Tongyoung Ⅰ, Namhae- Tongyoung Ⅱ, Jindong bay, Hansan bay, Cheonsu bay is estimated ₩6,215, ₩13,215, ₩6,405, ₩9,785, and ₩10,390 respectively. And, the total value of Namhae-Tongyoung Ⅰ, Namhae-Tongyoung Ⅱ, Jindong bay, Hansan bay, and Cheonsu bay is evaluated ₩108.8 billion, ₩357 billion, ₩118 billion, 210.2 billion, ₩ 245.8 billion respectively. Moreover, the yearly value of Namhae-Tongyoung Ⅰ, Namhae-Tongyoung Ⅱ, Jindong bay, Hansan bay, and Cheonsu bay is evaluated ₩6 billion, ₩19.6 billion, ₩6.5 billion, 11.6 billion, ₩ 13.5 billion. In conclusion, fisheries resource protected area has the higher conservational value. Consequently, it is essential for now or future generation's use of fisheries resources. In light of the fisheries resource protected area's value and importance, this should be promoted to the public including the local community who utilizes fisheries resource protected area wisely. Also, this suggests that the policy for fishery resource's creation and management is needed in fisheries resource protected area.

        As demand for Tenebrio molitor increases in animal feed market, improvement of mass-rearing indoor system became more crucial. This study is aimed at establishing the technology for conserving genetic resource of Tenebrio molitor, and increasing the technology utilization. This year, in advance, this experiment was designed for examining the developmental characteristics of eggs and larvae. To research the developmental characteristics under different temperatures, eggs, larvae and papae were treated at 17.5, 20, 22.5, 25, 27.5 and 30°C. At 25°C, larvae were exposed to various photoperiod conditions, LD 14:10, 12:12, and 10:14. The results show that the temperature range which affected hatching was 15~32.5°C. To achieve 70 percent or higher hatching rate 17.5~27.5°C was required. Furthermore, hatching occurred within 10 days, when the eggs were treated in 22.5~27.5°C. In regard of larval development, shorter developmental period, and higher pupation and eclosion rates were observed in 25~27.5°C. The shortest larval period was recorded at 14L:10D. At 10L:14D, in contrast, pupae showed the lowest chance of eclosion. Overall, larval development was optimal in long-day condition.

        This study was carried out to investigate the vascular plants of the protected area for forest genetic resource conservation in the National Yonghyeon natural recreation forest. The vascular plants collected 7 times (from February to September 2014) were consist of total 460 taxa; 95 families, 280 genera, 398 species, 3 subspecies, 50 varieties and 9 forms respectively. The 6 taxa of Korean endemic plants and 8 taxa of Korean rare plants were investigated. The floristic regional indicator plants found in this area were 43 taxa comprising 7 taxa of grade Ⅳ, 7 taxa of grade Ⅲ, 12 taxa of grade Ⅱ, 17 taxa of grade Ⅰ. The naturalized plants were 39 taxa, therefore naturalized ratio was 8.5%. 460 taxa listed consist of 189 taxa (41.1%) of edible plants, 155 taxa (33.7%)of medicinal plants, 177 taxa (38.5%) of pasture plants, 52 taxa (11.3%) of ornamental plants, 17 taxa (3.7%)of timber plants, 12 taxa (2.6%) of fiber plants and 3 taxa (0.7%) of industrial plants. The vegetation status of investigated area was comparatively well conserved, but human-induced damage is increasingly greater. Therefore, a long-term monitoring of vascular plants and vegetation movement must become accomplished.

        In order to analyze the effect of environmental protection on wind energy dissemination quantitatively, the onshore wind resource potential is estimated using Environmental Conservation Value Assessment Map and Korea Wind Resource Map. The onshore wind resource potential of 11 GW is calculated if wind farm development is prohibited within Class 1 area of Environmental Conservation Value Assessment plus 500 m buffer area. Therefore it is worried that environmental protection would be a practical barrier of accomplishing 4,155 thousand TOE target of wind energy dissemination until 2030.
