  • DMZ has a lot of natural resources. Also there is very important position as a ecological and geographical. Meanwhile, development schemes and plans were established but that was development to only simple plan such as a tourism and income without communication with local residents. This study was tried to exhibit increasing income of residents in DMZ area using FGI (Focus Group Interview) and SWOT analysis. First of all, analyzed the status of forest resources and carried out a Focus Group Interview targeting residents who live in around DMZ, and then suggest an alternative to increasing income and regional development in Yanggu-gun by SWOT strategies. As a result, realistic plan for achieving regional development is deregulation of the laws related to forest land use conversion for the forest product in DMZ area. Military experts and forest experts have to inspect the area for considering the practical application of the regulation in protected areas directly. National or local government has to effort pursuing future business for regional development through the communication with residents in DMZ area.

  • In order to explore feeding practices of large ruminants and methods followed in the rural areas, an exploratory survey was made during the period from January 1988 to January 1989 in eight different agro-ecological areas of Bangladesh in relation to the existing seasons and farmers' categories. The study shows what feeding practices varied (p<0.01) from area to area and season to season but not with the farmers' category. Considering the overall picture of feeding practices existing in the country, it can be observed that bigger proportion of farmers practiced stall feeding and tethering ($38.4{\pm}35.1$) followed by stall fed ($34.3{\pm}35.2$) and grazing or tethering ($17.3{\pm}26.7$). The figure with wider deviations indicates that farmers in the rural areas did not follow a smooth feeding practice, the system is rather a complex, heterogenous and a mere consequence of existing land use system. The results of feeding methods of by-product concentrates indicate that it also varied (p<0.01) from area to area but however, not with seasons and farmers' category. It is observed that bigger proportion of farmers fed concentrates to their animals mixed with water ($74.1{\pm}30.3$) followed by mixed with roughage and water ($10.3{\pm}13.3$) or fed alone ($5.6{\pm}14.2$). The method like feeding practice is also complex and heterogenous in the rural areas of Bangladesh. Hence, it is needed to develop a strategic feeding system and method identifying the problems associated with those.

  • The purpose of this study is for providing not only the latest design technique trend for zero waste fashion, but information about creative fashion design education through eco-fashion industry trend in globally and domestic which is focusing on eco-fashion labelling. The research were processed with literature related eco, sustainable, green fashion books, former articles, newspapers, and web sites. The results as follows; The certification about eco-fashion product is moving to 'Life Cycle Assessment' from focused on primary process like material, finishing, dyeing. Especially simplicity of process means reducing the wastes. And fabric wastage for adult outwear was estimated 15% percent of total fabric used in general design studios. Three cases for Zero waste fashion were as follows; First, Jigsaw puzzle by Timo Rissane and Mark Liu were different zero waste methods, but the result was same. Rissene's method was based on traditional cutting like 'cut and sew' but traditional cutting can lead to design that have an abundance of fabric and drape. Jigsaw of Rissene was approached with description a pattern-cutting technique in which all piece interlock with each other generating no waste from design production. Another Jigsaw by Liu was related with innovative textile design. DTP makes the possibilities for zero waste garment production almost endless. The dress intricately cut from 10 pieces, wastes none of the fabric required to make it. Second, Subtraction Cutting by Julian Roberts provides unexpected fluid, organic forms and zero waste fabric. Utilizing Roberts plug(tunnel) technique enables any part of the garment that is removed for fit or aesthetics to be reincorporated into the design of garment. Third was 'Bio Couture' by Suzanne Lee. She has created garments from cellulose bacteria which grow in a bathtub using only green methods addressing in such as way ecological issues and exploring the future of fashion design in conjunction with technology.

  • BACKGROUND: Fresh weight is one of the major quality measurement factors in determining the quality of fresh fruits. A practical method has been developed for rapid and non-destructive measurement using the Chlorophyll Fluorescence Image (CFI) technique to estimate changes in fresh weight of post-harvest products. METHODS AND RESULTS: Kiwifruit (Actinidia deliciosa) was used and measured for the fresh weight and CFI under different temperature conditions at 0, 10, and 20℃, from 0 to 21 days after storage (DAS). We observed the fresh weight of kiwifruit and measured the surface image for determining Fv/Fm value in terms of maximum quantum yield on each day. To estimate freshness of kiwifruit we applied linear regression between the measured fruit weights and Fv/Fm values. Results showed that fruit weights were reduced by 4% at 0℃, 6% at 10℃, and 14% at 20℃ for 21 days, respectively. And also, the value of Fv/Fm was shown as decreasing trend at all temperature conditions, especially at 20 ℃. Fv/Fm values showed highly significant correlation (R2>0.9) with fresh weight of kiwifruit at all different storage temperatures. CONCLUSION: Thus, CFI technique can be useful to estimate the fresh weight of kiwifruit.

  • 본 연구는 급진적인 환경면화를 대표하는 정보산업에서의 기술혁신의 진화과정을 탐색하였다. 진화론경제학이론을 바탕으로하는 동태적인 기술변화과정과 조직생태학이론으로부터의 산업-특정조직유형간의 관계를 결합하는 통합적인 모델을 개발하였다. 진화론경제학이론의 관점에 기초하여, 시감이 감에 따라 선택압력에 의해 미래기술의 지표로서 역할을 하는 소위 '기본설계'가 등장하고 그 기본설계는 일관성 있는 경로를 따르는 경향이 있으며, 그 기술이 한계점에 도달하기 전까지 기술경계들의 급진적 팽창을 촉진시키지만, 한계점에 도달했을 때 새로운 기술패러다임을 탐색한다는 것을 분석하였다. 아울러 조직군생태학 관점으로부터 5개 조직유형을 구분하였으며, 각 조직유형들은 산업내 기술변화의 진화과정에 따라 서로 다른 기회를 탐색한다는 것을 살펴보았다. 진화론경제학이론과 조직군생태학이론은 오랜 학문적 역사를 가진 생물학에 바탕을 두고 있으며 기존 전략 조직이론들이 설명하지 못했던 기술적 변화 또는 실패와 같은 전략적 사건들에 대한 인과관계를 설명하는데 깊은 통찰력을 제공해 준다. 따라서 향후 두 이론에 바탕을 둔 좀더 정교하고 통합적인 이론연구와 실증연구들이 지속될 필요가 있음을 말해준다.

  • Dokdo is a volcanic island, and its formative geological age took place at the end of the Pliocene Epoch. Dokdo is located at 131。 52′33" East longitude, and 37$^{\circ}$ 14′18" North latitude, and is consituted of 87 islands. The total area of Dokdo is 0.186 $\textrm{km}^2$ and the length of its coastline is 4 km. Ookdo is a treasury of fish resources where many varieties of fish including squid and Alaska pollack live in abundance of greatest importance. Dokdo is a forward fishery base. Ullung island is located at 37$^{\circ}$ 27′~37$^{\circ}$ 33′North latitude and 130$^{\circ}$ 47′~130$^{\circ}$ 56′East longitude. The area of Ullung is 72.92 $\textrm{km}^2$ and the length of its seashore is 44.21 $\textrm{km}^2$. The total marine product of Ullungdo(1995) is 9,066 tons (M/T). The largest is squid, 8,900 tons. For the sea area of the depths near the Ullungdo, coast, that of 50m or less is 2,477 ha, and that of 50- 100m is 1,471ha. This fact tells us that there is no extensive area of a very shallow sea, and that it is directly connected to the deep sea. Ullungdo is a treasury of marine bioresources with rich and varied fishes including squid and Alaska Pollack and many others. Presently there is a sovereignty dispute over Dokdo between Korea and Japan. Since A.D.512, Dokdo has been a part of territory of Korea. Dokdo is a part of Kyungsang-Bukdo, Ullung-gun, Ullung-up, Do-dong in the Korean administrative district division system. Japan strenuously claims sovereignty for significant economic reasons, including fishery rights, and has adhered to a contradictory position that "Dokdo is Japanese land" since Japan incorporated Dokdo into Japanese territory in 1905.ritory in 1905.

  • To ascertain the effect of over-expressed maize calreticulin in tomato plant on tobamovirus movement in addition to validating potentiality of the gene (ZmCRT) as a means for the virus-resistance resource, four ZmCRT-expressing homozygous lines were generated from the T0 plants as using an Agrobacterium-mediated transformation, nucleic acid analyses, and a conventional breeding method. Of them, a line was subjected to the bioassay for tolerances to tobacco mosaic virus-U1 (TMV-U1) and tomato mosaic virus (ToMV) followed by RT-PCR and a chlorophyll fluorescence quenching analyses. Both transgenic plants transcribing ZmCRT and wild-type plants showed no symptom by 20 days after viruses inoculation, however the photosystem II quantum yield parameter measured from the upper leaves of ToMV-inoculated plants revealed that ZmCRT transgenic plants have higher photosynthetic ability than wild-type ones at that time, which indirectly implies that over-expressed ZmCRT product acts as a barrier to the cell-to-cell and/or systemic movement of ToMV. Moreover, ZmCRT transgenic plants showed remarkably longer shoot length than wild-type ones in 40 days after TMV-U1 or ToMV inoculation each, which might be resulted from higher photosynthetic ability during the phase not yet showing any external symptoms. Collectively, over-expressed ZmCRT protein in tomato plants is able to interrupt the systemic movement of infected TMV-U1 and ToMV even though not perfect.

  • Tricholoma matsutake (Pinus mushroom, PM) is one of the most valued ectomycorrhizal fungi in Asia because it is an expensive forest product with a unique flavor and taste. Therefore, many studies have tried to successfully cultivate Tricholoma matsutake artificially in Korea and other countries. However, its physiological and ecological characteristics are still unknown. Thus, we need to understand the diversity and clusters of microorganisms related to Tricholoma matsutake and to identify their core microorganisms related to their growth and production. In this study, we obtained an average of 11,661 fragments from three pine mushrooms with metagenome (an assemblage of genes of all microorganisms in the natural world) analysis from a pine forest located in Pohang, Gyeongsang-Bukdo. Of these, the valid reads were on average 5,073 per sample available for analysis, and the average length of a read was 456 bp. There were an average of 33.3 phyla in the metagenome analysis. Firmicutes phylum made up on an average 46% of the phyla and was dominant among the phyla. The next dominant phylum was Proteobacteria at 27% followed by Bacteroidetes at 17%, Actinobacteria at 5% and Verrucomicrobia at 2%. The Proteobacteria phylum consisted of the γ-proteobacteria class at 54% followed by β-proteobacteria at 37%, α-proteobacteria at 6%, δ-proteobacteria at 2% and ζ-proteobacteria at 0%. The metagenome consisted of the Ruminococcaceae family at 17% followed by Pseudomonadaceae at 13%, Burkholderiaceae at 7%, Bacteroidaceae at 7%, Lachnospiraceae at 7% and Clostridiaceae at 6%.
