The purpose of this study is to provide basic data for establishing the activation strategies for the National Recreational Forests. This study was conducted on the natural recreation forests of Byunsan, Mt. Hoemun, Mt. Bajang in the western part of the National Recreational Forest Management Center in order to grasp the behavior and needs of the visitors and outline a activation plan through the IPA. Based on previous studies, 24 properties were derived and a survey was conducted for visitors National Recreational Forests from June 15 to June 30, 2017. As a result, the importance of the three areas was different. We found “Guest Discounts” attribute, and “Providing a guidance and infor mation smoothly” and “Staff kindness” were considered as being important, but not satisfied by users in Byunsan and Mt. Hoemun Recreational Forests, respectively. Likewise, and “Toliet location/ Management”, “Facility for Elderly/Disabled people”, and “Parking Area Location/Size” attributes were considered such factors in Mt. Bangjang.

Purpose: The purpose of this study was to determine the quality characteristics of gluten-free frying pre-mix with insoluble dietary fiber powder (IDFP) from Chinese cabbage by-product. Methods: Frying powder mix was prepared with 0.5, 1.0, 1.5 or 2.0% IDFP. Fried powder mix only whit brown rice powder was used as a control. Spreadability, pick-up ratio and color of batter, texture, moisture and oil contents, oil absorption and sensory evaluation of fried sweet potato were determined. Results: L and a-values of batter decreased with increasing amount of IDFP, whereas b-value increased with IDFP addition. Hardness and crispiness of fried sweet potato increased with IDFP addition until 1.5%. Moisture content of fried sweet potato increased with higher IDFP addition whereas oil content and oil absorption decreased with increasing amount of IDFP. Sensory evaluation of fried sweet potato showed the best results in the 0.5% of IDFP addition group. Conclusion: Overall preference of IDFP samples was significantly higher than that of control. Based on the study, the optimal amount of IDFP for gluten-free fried powder mix was determined to be 0.5-1.5%.

This study aims to identify the NVOCs(Natural Volatile Organic Compound) retention volume of Torreya nucifera stand and the characteristic of chemical compositions of the NVOCs emitted from it. This experiment was performed seven times in total from April to October, 2017 at Torreya nucifera temple forest of Naejangsan National Park Baekyangsa in Jangseong-gun. Two methods were used as the sampling methods of NVOCs. The first one was to use tedlar bags. After placing a tedlarbag over a branch and leafs, we injected pure air into it and captured NVOCs for 2 hours from 11 a.m. to 12 p.m. The second one was to capture NVOCs directly in a stand of Torreya nucifera used mini pump. When tedlarbags were used, the monthly NVOCs retention volumes of Torreya nucifera were 146,156pptv/April, 176,786pptv/May and 132,466pptv/June, 22,908pptv/July, 73,782pptv /August, 38,736pptv/September, 41,233pptv/October respectively. In addition, when measured using minipump in the stand, the monthly NVOCs retention volumes were 5,169 pptv/April, 11,940pptv /May, and 7,657pptv/June, 6,864pptv/July, 13,912pptv/August, 2,640pptv/September, 1,828pptv/October respectively. In order to identify the characteristic of compositions, 15 kinds of terpenes were analyzed, and their average was calculated seven times. As a result, limonene had the highest percentage of 43 to 52%, and α-pinene accounted for 35 to 39%. The NVOCs retention volume depended on the sampling method from Torreya nucifera stand. The highest NVOCs retention volume was at least 15 to 28 times higher, and most components of NVOCs were limonene and α-pinene. It is believed that NVOCs within the domain can be utilized as a baseline.
