국내 주요 인삼재배 산지 기반을 가진 전북 진안지역의 인삼 홍삼산업은, 재배농가 895호, 재배면적 402ha, 생산량 1,628톤, 홍삼가공업체 80개소, 판매업소 50개소로 지역경제의 25% 이상을 차지한다. 그러나 재배농가의 계열화 미흡(22%), 산지수집상(포전매매)에 의한 인근 유사 도매시장으로 재배물량과 부가가치 유출(78%), 가공시설의 노후화, 가공업체의 영세성(매출규모 연평균 2억11백만원)과 함께 중국, 캐나다, 미국 등의 국제 가격경쟁과 국내의 대기업 및 인삼산업 주요지역과의 경쟁이라는 상황에 직면하고 있다. 이러한 상황을 극복하고 지역특화명품산업으로 발전할 수 있는 방안으로, 인삼재배산지로서 원료공급지를 기반으로 하는 재배, 유통, 가공, 품질관리, 시설분야에 이르는 발전방안을 연구하였다. 산업원료 확보를 위해서는 인삼계열화 확대를 통해 원물 확보력을 강화하여야 한다. 재배분야의 경우에는 친환경재배 확대와 GAP 확대를 통해 원물의 품질경쟁력 뿐만 아니라 시장수요에 따른 브랜드마케팅 요인으로 특성화해야 한다. 유통분야는 계열화 확대를 통한 원물확보라는 산업경쟁력을 바탕으로 원료중심의 수취, 매취, 보관, 가공, 대형거래, 도소매 등 유통활성화와 유통규격포장 및 선별등급표준화를 통한 유통표준화를 추진하여야 한다. 가공의 경우, 원료홍삼 공급기능을 중심으로 가공산업을 선택 육성해야한다. 품질관리는 원물중심관리(성분, 잔류농약, 식품위생), 유통중심관리(연근, 등급), 경작중심관리(재배지, 재배자, 경작), 프로세스중심관리(재배 유통 가공 판매정보)로 구체화해야한다. 시설분야는 유통시설(대규모 집하시설, 보관시설 등 종합유통처리시설)과 가공시설(가공설비현대화, 가공공장 공인규격화;ISO, GMP, HACCP)의 지속적인 시설개선과 현대화를 추진하여야 한다.

In this study, one calculated the range of damage to the combustion characteristics according to the composition of LNG and the size of leaking holes, and analyzed the damage effect in case of leakage accidents caused by pipe damage in the re-gasification process for the LNG supply system. In order to confirm the combustion characteristics according to LNG composition, there was no significant difference in the result of risk analysis by LNG-producing areas. However, the higher the methane content of the components, the lower the risk of flash fire, hazardous areas of overpressure due to explosion, and thermal radiation damage caused by jet fire. In addition, one investigated the effect of leakage, holes, and ruptures on the risk range and explosions according to the size of the pipe-leakage hole. Also, the influence of overpressure and the range of damage from radiant heat could be predicted. One confirmed the effect of LNG composition and pipe-leakage size on fire and explosion.

The purpose of this study was to suggest customized management methods tailored to the characteristics of each type of park. Related literature was reviewed to determine the types of and management methods for urban parks to discuss the possibility of the involvement of citizens in park management and committing park management to the private sector. As a result of analyzing the literature, it has been found that each park should be managed separately according to its type in light of its characteristics and the strengths and weaknesses of each management method. For this reason, this must be a very important element for preventing damaging behavior at tourist destinations. First, natural mountainous parks are ordinary parks that do not require any professional management knowledge or skills. Accordingly, these parks should be managed by the districts in which they are located. Second, eco-oriented parks ask for specialized management. As domestic cases show, it will be advisable to commit the management of these parks to specialized, highly-experienced private organizations. Third, facilities-centered parks are large in size in response to the diverse needs of citizens, and it seems that a combination of different methods is better than merely sticking to any particular method.

In this study, four Korean black raspberry wines were developed from different regions in Korea; Gochang (G), Heongsung (H), Jeongup (J), and Sungchang (S). Their flavor profiles were determined using a combination of volatile analysis and sensory evaluation. From the volatile analysis of the developed wines, 8 acids, 17 alcohols, 12 esters, 9 terpenes, 3 aldehydes and ketones, and 4 miscellaneous compounds were identified. Preferences of appearance, aroma, full-body, and overall acceptability in the developed wines were determined using 9-point hedonic scale by 43 panelists, compared with one commercial black raspberry wine (Sunw). The sweetness, sourness, astringency levels were also evaluated using 9-point just-about-right (JAR) scale. The mean overall acceptability score of Sunw (5.58) was the highest among the tested wines, followed by G (4.81), S (4.44), H (4.41), and J (4.13) (p<0.05). Sweetness levels in the developed wines were overall lower than JAR level, while sourness and astringency levels were overall higher than JAR level.

A total of 24 families, 44 species, and 658 benthic macroinvertebrates were identified, and Ecdyonurus dracon Kluge (13%) was the dominant species in forested streams within the Yeonyeopsan (Mt.). A total of four habit categories (i.e., clingers (56%), burrowers (19%), swimmers (14%), and sprawlers (56%)) were identified, and clingers were the dominant habit at all survey points except point one (UP1). Habitat characteristics were depended on the hydraulic factors (e.g., flow velocity, depth, and substrates), water quality (e.g., DO and water temperature), and the habitat characteristics were differed in the riffle, which has a faster the flow velocity, compared by in the stagnant pool. In other words, in riffles, the clingers dominated in high flow velocity with the large maximum and median grain size for substrates in the habitats regardless of depth, but the burrowers and sprawlers were dominant in low flow velocity with the small maximum and median grain size for substrates in the habitats. Moreover, DO and flow velocity were in positive correlation (y = 0.6666x - 0.659, R² = 0.0851), and the habitat for burrowers was wider than that for sprawlers or clingers. The water depth was negatively correlated with water temperature (y = -26.397x + 283.87, R² = 0.1802) since the water temperature is more sensitive to insolation in shallow depth. pH was positively correlated with water temperature. The investigation of the habitat characteristics by separating the relations between pH and DO in upstream and downstream showed the low pH and high DO in the upstream with a high crown density of 68%, regardless of community composition. On the other hand, high pH and low DO in the downstream with a relatively low crown density of 51%. It was considered that the riparian forest played a role in suppressing the growth of attached algae and the controlling water temperature in headwater streams. Our findings identified the habitat characteristics of benthic macroinvertebrates in a headwater stream. We expected that the finding can provide reference data for suggesting conservation and management plans in a headwater stream and increasing academic value.

This study carried out stability evaluation for design flood stage of vegetation models with river sites using 1D HEC-RAS and 2D RMA-2 numerical models. The vegetation models established in this study were divided into which channel reaches consist of urban, rural and mountain rivers with the social and cultural significance of the sites. Examination results from the numerical models showed a similar aspect with the design flood stage of these rivers before vegetation modeling. Also, no embankment overflow was shown from the urban river with additional vegetation density of 25%, although there were approximately 0.20m rising in the flood stage. In case of ural and mountain rivers, vegetation models showed scarce rising in flood stage.
