본 논문은 ESG에 따른 신 산업기술 재편으로 V4 지역은 한국의 배터리 제조기지의 변곡점을 제기하고자 한다. 이는 코로나19에 따른 경제 위기속에 러시아-우크라이나 전쟁과 미-중간의 패권을 겨루고 있기 때문이다. 그로 인해 글로벌 공급망 시장은 단절된다. 중국과 러시아로부터의 유럽으로 광물, 곡물조달이나, 가스, 심지어 밀 수입이 여의치 않는 환경에서, 신 공급처의 다각화가 나타나고 있다. 보호주의와 글로컬로써, 이 지역은 러시아-우크라전쟁으로 완충지대(친러, 헝가리)에서 고립지대(반러, 폴란드)로 활용된다. EU 테이퍼링 기간과 높은 인플레이션으로 세계경제 성장은 더 둔화될 전망이다. 논문의 경우 이 지역의 시장단절(chasm) 방안을 다룬다. 이러한 변화에 신사업 기술의 전환과 에너지 공급에 따른 독일의 산업위축이 지난 20년간 경제성장 원동력을 잃게 될 수도 있다. 이는 명목 지표에서 현지 시장 단절(chasm)이 발생하고 있다. 다른 한편으로 한국은 희토류소재 공급망의 불균형에 따른 우회 개발공급 지역으로써, V4지역에 AI를 접목한 에너지 발전 수출(원전 및 전기-수소 발전)지역으로 전개해야 한다. 본 논문은 이러한 산업 연계로 인한 시장단절을 극복하려면, 신에너지 개발과 플랫폼 규모화를 이루고, 세계 각국에서 신뢰적인 공급 기술(차세대 전지, 재활용기술, 저가LFP)을 다각화를 형성할 수 있음을 방증하고 있다.

This experimental demonstration has successfully shown that it is possible to use direct sunlight for the illumination of deeper building zones using the material for light path system(light duct). Three kinds of reflectors which were 95% Silver vaporizing fixed, 85% Anodized and 85% Hot melted applied to evaluate and compare their performances each others. Also, these three kind of reflectors were compared in view point of economics. The most high performance was obtained in 95% Silver vaporizing fixed reflector hater than another reflectors of 85% Anodized reflector and 85% Hot melted reflector even though more high production cost in 95% Silver vaporizing fixed reflector. The rest two reflectors of 85% Anodized and 85% Hot melted $10{sim}15%$ less performance than 95% Silver vaporizing fixed reflector but their production cost were low than the production cost of 95% Silver vaporizing fixed reflector which identified very weak and light yellow color in the light.

동북아시아 국가들은 세계 무역 및 투자에 중요한 역할을 담당하고 있다. 동북아시아 역내 및 역외 국가들과의 경제교류는 앞으로 계속 늘어날 것으로 전망되며, 이로 인한 국제상사분쟁은 국제상사중재 등 ADR에 의해 해결될 수밖에 없을 것이다. 동북아시아에서 ADR 제도가 발전되기 위해서는 무엇보다도 한국의 대한상사중재원, 북한의 조선국제무역중재위원회, 중국의 중국국제경재무역중재위원회, 일본의 일본상사중재협회, 러시아의 러시아상공회의소 부설 국제상사중재법정, 카자흐스탄의 카자흐스탄국제중재기관, 몽골국가중재법정 상호간의 중재 업무 전반에 관한 협력제제가 구축되어야 할 것이다. 국제상사중재에 관하여 동북아시아에 새로운 바람이 불고 있다. 경제자유구역 및 남북간 경제교류와 관련한 상사분쟁이 상사중재로 해결될 수 있는 법, 제도적 기반이 마련되었기 때문이다. 지난 해 한국에서는 대한상사중재원 주도하에 무역클레임 센서스가 실시되고 국제중재세미나가 개최되었으며 국제중재규칙이 제정(2007년도 2월 1일 시행 예정)된바 있다. 동북아시아 지역에서 국제상사중재제도가 발전되고 저변이 확대되기 위해서는 중재기관들 간의 협조체제가 구축되어야 할 것이다. 한편 한국도 동북아시아의 중재허브로 성장하기 위해서는 국제금융, M&A 등 중재 영역을 확대하고 경제자유구역 및 남북상사중재 등과 같은 새로운 영역에 대처를 잘 해야 할 것이다. 아울러 정부 당국의 재정적 지원과 행정적 배려도 수반되어야 할 것이다.

Calocybe indica, known as milky white mushroom, grows and cultivated in the sub-tropical and temperate zones of South Asia. We investigated the most suitable supplements and their levels for the commercial cultivation of milky white mushroom. Rice bran, maize powder, and wheat bran with their different levels (10, 20, 30, 40, and 50%) were used as supplements to evaluate the yield and yield contributing characteristics of C. indica. Primordia initiation was observed between 13.5 and 19.3 days. The results indicated that the 30% maize powder supplement was effective for producing viable fruiting bodies. The maximum diameters of the pileus and stalk were observed with 30% maize powder. The highest biological and economic yield and biological efficiency were also obtained with 30% maize powder as a supplement. The results indicate that increasing the supplement level resulted in less biological efficiency, and that 30% maize powder was the best supplement level for rice straw substrate to cultivate milky white mushrooms.

As agricultural machinery has become larger and tillage practices have changed in recent decades, compaction as a result of wheel traffic and tillage has caused increasing concern. If strategies to manage compaction, such as deep tillage, could be applied only where needed, economic and environmental benefits would result. For such site-specific compaction management to occur, compacted areas within fields must be efficiently sensed and mapped. We previously developed an on-the-go soil strength profile sensor (SSPS) for this purpose. The SSPS measures within-field variability in soil strength at five soil depths up to 50 cm. Determining the variability structure of SSPS data is needed for site-specific field management since the variability structure determines the required intensity of data collection and is related to the delineation of compaction management zones. In this paper, soil bin data were analyzed by a spectral analysis technique to determine the variability structure of the SSPS data, and to investigate causes and implications of this variability. In the soil bin, we observed a repeating pattern due to soil fracture with an approximate 12- to 19-cm period, especially at the 10-cm depth, possibly due to cyclic development of soil fracture on this interval. These findings will facilitate interpretation of soil strength data and enhance application of the SSPS.

Taiwan, formerly known as Formosa, located on tropical and subtropical climate zones with abundant biological resources. According to the latest version of the Flora of Taiwan, there are 4339 species of vascular plants including 1054 endemic species. First, Taiwania (Taiwania cryptomerioides), named after its native island of Taiwan, have been isolated more than 500 secondary metabolites, including lignans, terpenoids, steroids, and flavonoids. Several of the metabolites are reported to have antibacterial, antifungal, antimite, antitermite and antitumor activities. In order to investigate plant secondary metabolic diversity toward industrial applications, we established deep transcriptome resources for non-model plants and fungi to produce terpenoid metabolites of economic importance. Second, many plants of Lauraceae have been utilized in folk medicine for their exciting bioactivities. The twigs and leaves from 27 tree species of Lauraceae grown in Taiwan were performed to evaluate potential bioactivity. The leaves of Cinnamomum osmophloeum are traditionally used in folk medicines, and many biological activities have been identified, such as antibacterial, antifungal, antitermite, antidiabetic, antihyperuricemia, antiinflammatory, and antioxidant activities. However, C. osmophloeum has nine chemotypes with various secondary metabolite profiles. In order to efficiently produce active compounds, we established the genetic markers to identify the chemotype plants. Finally, Cinnamomum kanehirae is the host of the medicinal mushroom Antrodia cinnamomea. Several in vivo and in vitro studies indicated that A. cinnamomea possesses a diverse range of biological activities. Because of the potential pharmacological application, we established the transformation system to enhance the triterpenoid contents production.

This study is to analyze establishment status and planning characteristics of the landscape master plan of 22 cities and counties in Jeollanam-do, Korea. The landscape master plans have been established in 19 cities and counties and among them they were established in 11 cities and counties before 2010. They tend to be made in city governments earlier than county governments. Community visions are implied with four meanings, 'landscape ecological', 'administrative economic', 'historical cultural', 'abstraction sensitive' in expression. For setting zones, axises, and bases of landscapes, characteristics of each landscape zone are emphasized with unification and connectivity of axises and bases of landscapes as one unit to local governments. Proposal of design principle or guideline of landscape by elements tend to be higher than landscape types. Locational characteristics of local governments have influenced to landscape types and characteristics of natural environments have been strongly reflected in landscape plan in particular.

During the 11 year period of 1995-2005, there was about a 40% increase in the world copper demand mainly because of the Asian economic growth. In the increase, about a half was consumed by China. Most of the China's copper demand increase has been taken place over the final 5-6 years of that period. The growth is expected to continue for several years, and in 10 years or sooner the same situation is expected for India. Copper is the third metal in global demand, but its little abundance in the Earth's crust is not well recognized. From the production rate and the abundance, a copper shortage, or crisis, has a high probability than the other metals. Deep ocean mineral resources such as manganese nodules in the Clarion-Clipperton Fracture Zones, Kuroko-type massive seafloor sulfides (SMS), and cobalt-rich manganese crusts in the EEZ and the high sea areas have big potentials for the future sources. We need to re-evaluate their potentials as copper resources and other metals to realize their developments. The same situation is under progress in the hydro-carbon markets. Methane hydrates that are classified into non-conventional hydro-carbon resources have an important role as the future sources, too.

Macroalgae are important primary producers in marine ecosystem. They don't only play an important role as bioindicators but also provide economic resources for humans. Seasonal and vertical variations in seaweed species composition and biomass were examined to determine the ecological status of seaweed beds around Udo, near Jeju Island. We obtained samples at two sites in the high-intertidal to subtidal zones using the quadrat method between June 2010 and May 2011. A total of 262 species were collected, including 31 green, 61 brown, and 170 red algae. The composition of algal species revealed a decrease in species growing in cold water in comparison with the list 20 years ago. The macroalgal mean biomass (g wet wt $m^{-2}$) was 3,476 g and 2,393 g from the two sites, respectively. Ecklonia cava had the greatest biomass at both sites. The seasonal dominant species by biomass at site 1 from the low-intertidal to 1-3 m depth of the subtidal zone was mostly comprised of thick-leathery form, such as Sargassum hemiphyllum, S. coreanum, and Ecklonia cava, whereas site 2 was comprised of the turf form, such as Chondrophycus intermedius, Chondracanthus intermedius, Dictyopteris prolifera, and Gelidium elegans. The current ecological status of the seaweed community in Udo is stable based on diversity and dominance indices.
