The areas of soybean (Glycine max (L.) Merrill) cultivation in Gangwon-do have increased due to the growing demand for well-being foods. The soybean barcode system is a useful tool for cultivar identification and diversity analysis, which could be used in the seed production system for soybean cultivars. We genotyped cultivars using 202 insertion and deletion (InDel) markers specific to dense variation blocks (dVBs), and examined their ability to identify cultivars and analyze diversity by comparison to the database in the soybean barcode system. The genetic homology of "Cheonga," "Gichan," "Daewang," "Haesal," and "Gangil" to the 147 accessions was lower than 81.2%, demonstrating that these barcodes have potentiality in cultivar identification. Diversity analysis of one hundred and fifty-three soybean cultivars revealed four subgroups and one admixture (major allele frequency <0.6). Among the accessions, "Heugcheong," "Hoban," and "Cheonga" were included in subgroup 1 and "Gichan," "Daewang," "Haesal," and "Gangil" in the admixture. The genetic regions of subgroups 3 and 4 in the admixture were reshuffled for early maturity and environmental tolerance, respectively, suggesting that soybean accessions with new dVB types should be developed to improve the value of soybean products to the end user. These results indicated that the two-dimensional barcodes of soybean cultivars enable not only genetic identification, but also management of genetic resources through diversity analysis.

In this study, after carrying out a bending test that targeted the frames of plastic film greenhouse, the load-displacement relationship was analyzed to be used as basic data to develop greenhouse construction and maintenance guidelines. As a result, regardless of the shapes of the specimen, the yield and the maximum load increased as the size of the specimen increased. The displacement also showed the same pattern. A steel pipe showed lower yield and maximum load than a square pipe, and the displacement was large. In the steel pipe case, the displacement under the yield and maximum load was in the range of approximately 1.42-4.20mm and 5.80-24.13mm, respectively. In the square pipe case, the displacement under the yield and maximum load was in the range of approximately 1.62-3.00mm and 3.13-8.01mm, respectively. Further, a large difference was observed between the result of this test and the values calculated by a conventionally provided standard. In particular, not much difference was found from the result of this test in the case of a purlin member from the values provided by previous researches. However, a large difference was observed in the column or main rafter members. Furthermore, when a wide-span and venlo type, which is a glasshouse, was used as a target(h/100 and h/80), the displacement under the yield and maximum load was approximately 28.0mm and 35.0mm, respectively, which showed a large difference compared with the Netherlands standard(14.0mm) of a glasshouse. Further, in the main rafter case, a large difference was observed in the displacement limit according to the width(i.e., span) of the greenhouse where members are used. Therefore, because the displacement limit can vary depending on various factors such as type, form, and size of a greenhouse, we determined that studies or tests that consider these factors should be carried out to reflect them in the construction and maintenance of greenhouses.

자원식물은 인간의 천연물에 대한 관심 고조와 미래 생물자원으로서의 경제적 가치가 재인식되어 미국을 비롯한 선진국은 오래전부터 유용한 식물자원 보존과 이를 이용한 산업화에 정부가 앞장서 추진하고 있다. 더욱이 우리나라는 국토면적에 비해 많은 식물종이 분포하고 뚜렷한 4계절과 다양한 토양특성으로 우수한 기능성식물자원이 많으며 이들 식물자원의 이용과 효능에 대한 풍부한 지식이 전통적으로 이어져 왔다. 그럼에도 불구하고 우수한 자원식물에 대한 보존과 이용이 과학화 체계화되지 못하여 세계적인 품종이나 제품개발은 미흡한 실정이다. 그동안 우리나라는 토종자원에 대한 관심과 꾸준한 연구개발로 농촌진흥청 보존 농업유전자원은 세계 6위 수준('10년말 291천점) 이며, 멀티기능 유용물질 함유 작물 개발 및 실용화 기술수준도 기술력 지수 세계7위로 높게 평가되고 있다. 그러나 이들 자원식물로부터 유용물질을 이용하여 세계시장을 선도하는 천연물신약, 건강기능성식품, 한방화장품, 천연 색소 및 향료 등의 제품개발은 미흡하여 앞으로 유망 자원식물을 이용한 체계적이고 과학적인 고부가 산업 육성을 위한 집중적인 투자가 필요한 시점이다. 자원식물을 이용한 천연물 신약개발은 고부가가치 제품과 산업재산권 확보가 가능하므로 수입 대체와 기술 및 제품수출이 충분히 이루어질 수 있다고 보여 현재 연구개발 중인 신약후보 도출 및 임상개발 과제의 수요를 반영한 후 단계별 대규모 신약개발 노력이 필요하다 하겠다. 건강기능 식품 개발은 고령사회 진입과 노령인구 증가로 노화억제 및 고령자 건강유지용 식품비중이 지속적으로 높아질 것으로 추정되어 약용식물을 소재로 개인 맞춤형 나노바이오 건강기능성 식품 개발을 통한 다양한 제품개발이 요구된다. 또한 우리나라 화장품분야의 전반적인 기술수준은 세계최고 기술의 62% 수준이나 화장품 소재의 자원식물 발굴과 나노기술 접목을 통한 효능의 극대화는 소비자의 웰빙 트랜드와 외국화장품과의 차별화 전략에 맞물려 국내 한방화장품의 세계화가 가능한 품목 중 하나이다. 식용 및 염색용 색소도 자원식물이 풍부하고 천연색소 시장이 크게 확장되고 있어 자원식물 중 경제성과 기술적 개발 가능성을 고려하여 단계적인 개발이 요구된다. 특히, 우리의 식물자원, 전통지식, 과학기술이 통합되어 효능을 현저하게 상승시키는 천연물신약, 건강보조식품, 화장품 등이 개발된다면 세계시장을 선도할 날도 멀지 않을 것으로 기대한다.

This paper analyzes Cuba's market-oriented reforms to alleviate essential problems with socialist countries such as soft budget constraints and incentive problems. It also discuss about effectiveness of industrial policy as a development strategy. The soft budget constraints and incentive problems resulted in the collapse of Soviet bloc and COMECON in early 1990s. After the collapse, Cuban economy suffered a steep dive, and national income tumbling down rapidly. Cuban faced serious shortages of food, gasoline, and other basic necessities of life. To halt and partially reverse economic downturn and dire austerity in the 1990's, the Cuban government made some partial reforms to the inherited Soviet system of cental planningand faced severe shortage in food, energy, and daily necessities. In response to the economic crisis. Cuba introduced economic reforms and implemented industrial policy as a development strategy as long as Cuba maintained a strong socialist country. Cuban government established the economic free zone law and attempted to induce foreign direct investment by implementing export-led industrial policy. Fiedel Castro approved the Law No. 165 "Free Zones and Industrial Parks", in 1996. However, Cuba's ESZ strategy seems to have failed because of the U.S. sanctions, but also because of Cuba's own policies, which do not allow foreign investors to hire workers directly and impose a high implicit tax on wages. By limiting advanced techniques of personnel and organization management, indirect employment can result in lowering work efforts and productivity of workers, and aggravating production efficiency in the ESZs. Another reason to fail comes from the double wage structure due to the double monetary-exchange rate system. Most of the high non-wage costs result from the double exchange rate system. Due to Cuba's imbalanced industry and production structures, concentrated labor force, and urbanization and centralization of agriculture production, the industrial transformation development model suggested by Lewis has not been successful unlike other Asian agriculture-led development model. Cuba has to overcome many difficulties in implementing industrial policy as a development strategy.

TTo increase productivity of a strong extracellular alkaline protease (BCAP), stable strains of Bacillus clausii I-52 carrying another copy of BCAP gene in the chromosome were developed. Integrative vector, pHPS9-fuBCAP carrying BCAP promoter, ribosome binding site, signal sequence and active protease gene was constructed and transferred into B. clausii I-52, and integration of the constructed plasmid into chromosome was identified by PCR. An investigation was carried out on BCAP production by B. clausii I-52 and transformant C5 showing the highest relative activity of alkaline protease using submerged fermentation. Maximum enzyme activity was produced when cells were grown under the submerged fermentation conditions at $37^{\circ}C$ for 48 h with an aeration rate of 1 vvm and agitation rate of 650 rpm in a optimized medium (soybean meal 2%, wheat flour 1%, sodium citrate 0.5%, $K_2HPO_4$ 0.4%, $Na_2HPO_4$ 0.1%, NaCl 0.4%, $MgSO_47H_2O$ 0.01%, $FeSO_47H_2O$ 0.05%, liquid maltose 2.5%, $Na_2CO_3$ 0.6%). A protease yield of approximately 134,670U/ml was achieved using an optimized media, which show an increase of approximately 1.6-fold compared to that of non-transformant (83,960 U/ml). When the stability of transformant C5 was examined, the integrated plasmid pHPS9-fuBCAP was detected in the transformant after cultivation for 8 days, suggesting that it maintained stably in the chromosomal DNA of transformant C5.

This study was carried out to investigate how the basic plan of the Saemangeum development project that has been developed by the government since 1991 has been changed and to present a new development strategy by analyzing the future value and tourism resource value of Saemangeum development. The research methodology is based on the in - depth analysis methodology of the time series research materials and press releases published by the Saemangeum Development Administration, which oversees the development of Saemangeum. The government announced a plan to significantly reduce agricultural land and increase the proportion of non-agricultural land to 70% in order to create a multifunctional complex. After that, the government revised the basic plan of Saemangeum in 2014 and changed the plan to tailor the investment demand in order to cultivate investment demand, and introduced the special economic cooperation system for global economic cooperation. Therefore, the purpose of this paper is to analyze the process of Saemangeum development to date and to evaluate the value of Saemangeum development as a tourism resource, centered on the Master Plan of the Saemangeum Development Project changed by the government. Based on the results of this analysis, I would like to present the vision of Saemangeum tourism development considering Saemangeum 's environment and characteristics of the surrounding scenery by referring to trends and similar cases of international tourism.

북한(北韓)의 경제개발전략(經濟開發戰略)의 제특징(諸特徵)은 저렴한 농산물가격(農産物價格)에 의한 농업부분(農業部分)에서의 잉여(剩餘), 저임금(低賃金)에 의한 도시노동자(都市勞動者)들로부터의 잉여(剩餘)를 가지고 경제발전(經濟發展)을 이룩하는 것이라 요약할 수 있다. 농민(農民), 도시노동자(都市勞動者) 양측(兩測)을 희생시키면서 유지되어 온 이러한 성장구조(成長構造)는 원래 같으면 저농산물가격(低農産物價格)${\rightarrow}$저임금(低賃金)${\rightarrow}$축적자금확대(蓄積資金擴大)${\rightarrow}$재투자(再投資)${\rightarrow}$생산량증가(生産量增加)${\rightarrow}$소비수준 (消費水準) 증가(增加)로 점진적으로 발전해야만 하는 것이다. 하지만 이러한 성장전략(成長戰略)은 처음부터 철저히 부정되어 왔다. 먼저 농촌부분(農村部分)부터 보면 농촌협동조합(農村協同組合)에서의 소유제도(所有制度), 분배제도(分配制度)의 문제(問題)로 인해 농민(農民)의 근로의욕(勤勞意欲)이 크게 상실되었고 그 결과(結果) 농업생산(農業生産)은 저하되었다. 한편 도시부분(都市部分)에서는 인민(人民)들의 저소비(低消費)의 결과(結果)로 축적된 자금(資金)이 군사부분(軍事部分)에 집중적으로 투자됨으로 인해 그 투자효과(投資效果)가 제 구실을 못하게 되었다. 뿐만 아니라 자급자족지향형(自給自足指向型)의 중공업화(重工業化)는 중공업(重工業)과 관련산업(關聯産業) 상호간(相互間)의 수요(需要)만을 충족시켜 왔다. 그 외에 기업(企業)이 국가(國家)의 지령(指令)에 의해서만 움직이는 국영기업관리체제(國營企業管理體制)의 비효율성(非效率性)도 지금의 북한경제(北韓經濟)를 침체(沈滯)의 늪에서 헤어나지 못하게 하는 주요(主要)한 요인(要因)으로 작용했다. 농업생산(農業生産)의 정체(停滯), 중공업(重工業)을 위한 중공업정책(重工業政策)이라고 하는 왜곡된 투자구조(投資構造), 기업관리체제(企業管理體制)의 비효율성(非效率性)은 북한(北韓)의 계획경제순환구조(計劃經濟循環構造)를 기본(基本)부터 뒤흔들기 시작하면서, 급기야 1980년대 후반부터는 순환구조(循環構造) 그 자체(自體)를 마비시키는 사태(事態)로까지 발전했다. 순환구조(循環構造)의 마비(痲痺)라고 하는 심각한 경제난(經濟難)을 타개하기 위해 북한(北韓)은 나진(羅津) 선봉(先鋒) 자유경제무역지대(自由經濟貿易地帶)를 설치(設置)하고 새로운 자금축적원(資金蓄積源)으로서 외국인직접투자(外國人直接投資)를 유치하는 개방정책(開放政策)을 추진하여 왔다. 하지만 북한(北韓)의 경제(經濟) 순환구조(循環構造)의 마비(痲痺)를 풀 수 있는 근본적(根本的)인 해법(解法)은 어디까지나 그 발단(發端)인 농촌(農村)의 경제체제개혁(經濟體制改革), 농(農) 경공업(輕工業)을 위한 중공업(重工業), 국영기업(國營企業)의 개혁(改革) 등을 과감히 실시하는 것이다. 왜냐하면 해외직접투자(海外直接投資)라는 새로운 자금축적원(資金蓄積源)은 어디까지나 지금의 악순환구조(惡循環構造)를 임시적(臨時的)으로 정지시켜 주는 보완적(補完的)인 조치(措置)에 불과하기 때문이다.
