Agriculture has played a significant role in the national economy, contributing to food security, driving economic growth, and safeguarding the dietary habits of the population. Korean agriculture has been compelled to focus on intensive farming due to its limited cultivation area, excessive input costs, and the limitations of agricultural mechanization. In the Republic of Korea (R.O.K), the concept of environmentally friendly animal agriculture began to be introduced in the early 2000s. This concept ultimately aims to cultivate sustainable animal agriculture (SAA) through environmentally friendly production practices, ensuring the healthy rearing of animals to supply safe animal products. Despite the government's efforts, there are still significant challenges in implementing environmentally friendly agriculture and SAA in the R.O.K. Therefore, the objective of this review is to establish the direction that the animal agriculture sector should take in the era of climate crisis, and to develop effective strategies for SAA tailored to the current situation in the R.O.K by examining the trends in SAA in the U.S. The animal agriculture sector in the U.S. has been working towards creating a SAA system where humans, animals, and the environment can coexist through government initiatives, industry research, technological support, and individual efforts. Efforts have been made to reduce emissions like carbon, and improve factors affecting the environment such as the carbon footprint, odor, and greenhouse gases associated with animal agriculture processes for animals such as cattle and pigs. The transition of the U.S. towards SAA appears to be driven by both external goals related to addressing climate change and the primary objectives of responding to the demand for safe animal products, expanding consumption, and securing competitiveness in overseas export markets. The demand for animal welfare, organic animal products, and processed goods has been increasing in the U.S. consumer market. A major factor in the transformation of the U.S. animal agriculture sector in terms of livestock specifications is attributed to environmentally friendly practices such as high-quality feed, heat stress reduction, improvements in reproductive ability and growth period reduction, and efforts in animal genetic enhancement.
The development of IT expanded the scale of e-commerce, and grew large Internet shopping malls. As having raised the consumers' interest in overseas direct purchase(ODP) recently, the number and purchasing amount of ODP are constantly increasing. However, consumers need to pay attention to the potential problems which might happen by consumer's damage and conflict, as increasing the consumption through ODP. Because consumer's damages on utilizing ODP happen to the reason such as the trust problem between business and consumer due to the way which traded non face to face, non-compliance of goods delivery, returns, and refunds, and information asymmetry of items, a large number of consumer's damages in a wide range are much more likely to occur nowadays. The purpose of this study is to analyze the current state of ODP, and propose consumer damage's reduction and policy of the government through pre or post scheme for consumer damage's relief and consumer protection. As the compensation for consumer damages is actually inadequate, this study proposed a feasible alternative to the adoption of e-commerce insurance for both aggressive compensation and protection for consumer's damages and risk transfer and sustainable development of e-commerce.

Even though various geological attractions are distributed domestically, the geological attractions are rarely utilized as field course site. The purpose of this study is to make Seonangbawi area as the field course site after geological investigations are carried out in detail. Seonangbawi is located about 1km southeast from Songjiho beach in Gangwon-do. Seonangbawi area is simply composed of Cretaceous Seokcho granite with the overlay of Quaternary alluvium. Geological field course in the Seonangbawi area will be useful to the student and citizen for developing the knowledge of geological phenomena, such as the formation of granite and minerals, and weathering process. In addition, the student and citizen can develop the knowledge of the geological structures, such as joint (N50E/80NW, N40W/84SW), fault (N42W/83SW), foliation (N32E/54SE), and dyke (N35E/40SE, N26W/63SW), and geographical features, such as tor, taforni, groove, and gnamma in the field. Accordingly, the Seonangbawi area is the best place to learn various geological and geographical phenomena and to discuss the origin of Seonangbawi with limited space.
This research was conducted to apply the QUAL2E model to be adopted to the Nam river under current water quality conditions. The survey area of total 60 Km was divided into five reaches. Each reach was then subdivided into the uniform computational elements of 1.5 Km. Based on the stream characteristics, nine sampling stations consisting of six at main streams and three at tributaries were selected. The field data were obtained from the selected stations twice during October of 1991 and May of 1992, which represented the cold weather and low flow, also the warm weather and low flow conditions, respectively. As the results of sensitivity analysis of the model, the important parameters were the rates of BOD decay, Org-N oxidation, $NH_3-N$ oxidation, Org-P decay. The calibrated and verified results by QUAL2E model were correlation coefficient of $0.45{\sim}0.94$. The results displayed a good agreement between the variables of the field measurements and the model simulations, indicating a potential use of the QUAL2E model for the water quality assessment in the Nam River.

Recently in Korea, integration of F.P. & MCH programs for effective and efficient implementation of the health programs has been discussed actively. In fact, categorical health workers in fields have been trained and changed as an integrated health workers by government. But one of the most important problems that had to be solved for successful integration of F.P. and MCH programs, is that there must be a common indicator for the evaluation of the two health services (integrated indicator). We regarded reproductive efficiency (=R.E.) that had been proposed by Charlotter M$\ddot{u}$ller et al, as the good integrated indicator. The object of this brief article is to introduce the meaning of reproductive efficiency and to illustrate the usefulnesses of R.E. as the integrated health indicator by applying this indicator to the data from preliminary survey of Seosan demonstration project for integration of F.P. & MCH service supported by WHO. The results and conclusions are as follows 1) Definition of R.E. is the percentage of pregnancies that succeed in production normal, surving children after taking into account the frequency of all measurable types of adverse outcomes (End point for evaluation of survival is one year of age). 2) On the basis of the past pregnant history, reproductive efficiency of the 2,484 eligible women (15-44 years) was roughly 75% (But, in the concept of good births, it is not regarded whether the survived infant is normal health or not). 3) Compared with the results of the other two surveys of the rural area in Korea, reproductive efficiency has been slightly decreased than before, in spite of family planning and MCH services for past 20 years. Because the quantity of increased abortion rate overwhelmed that of the decreased infant mortality rate. 4) Reproductive efficiency has the object for measure many events during the period from the conception (Wanted pregnancy) to an normal surviving children as an 1 year of age. So these heterogenous adversities, ie, induced abortion, still births, spontaneous abortion, neonate & infant death, are aggregated as R.E. However, if the information of these important events and reproductive efficiency were given, R.E. is used as the comprehensive evaluation indicator for F.P. and M.C.H. after meticulous analysis the various components of R.E. 5) Economic loss for adverse outcomes of preg were pregnancy were calculated applying the medical cost at the relatively small sized hospital of small city. Economic loss for 100 cases of adverse outcome is 10,420,000 won, and economic loss for infant death is 46.1% of the total loss. So, it is rational to invest much more effort and than before to MCH programs.

In this paper, first I try to sketch the changing Japanese labor market after 1990s, and then examine the so-called "Job $Caf{\acute{e}}$ program" in detail, which was initiated in 2004 by central and local governments to help young people fine suitable jobs, and finally investigate the possible direction for future labor policy as an important tool for revitalize the local economy. Latter half of 1990s witnessed the high unemployment rate among the population aged twenties in Japan, and the number of 'shinsotsu-mugyo', i.e. population not at work after completing high school or university, NEET (not in employment, education or training) and 'freeters' have grown rapidly. "Job $Caf{\acute{e}}$ program" was initiated as a public response to the increased youth unemployment, aiming at assisting young people's transition from education to career. In the Job $Caf{\acute{e}}$ program, job information service by MHLW, information service for high school students and university students by MEXT, placement service of career internship by METI are integrated into one service, and are provided by local government initiative, therefore named as "one stop service of employment". Although it is highly appreciated for one stop service, the Job cafe program has criticized for paying too much attention to the performance of projects, such as the number of users, and the number of successful job matching. At the final section of the paper, more practical spatial unit for executing effective regional plan on local employment and more empirical research on job search behavior are discussed.
The culture of memory in France regarding slavery and slave trade has slowly been expanding its horizons: from limited perspective focusing on abrogation of slavery to inclusion of discussion on real experiences and suffering of African slaves. This change has been particularly noticeable since the 150th anniversary of abrogation of slavery in France in 1998. It was the year that citizens of French overseas territories that had internalized this painful and shameful history of suffering formed a visible social movement. For the last two decades, the French government has also demonstrated consistent, proactive and prompt response to discussions of issues rooted in slavery in overseas territories, wherein slavery is the root of fundamental problems. In particular, when the Taubira Law (2001) was passed in the Senate, the Committee for the Memory of Slavery was established. This committee has since contributed to better assessment and understanding of French history of slavery and slave trade. Such was the profound as well as significant change in public perception as well as in legal and social aspects that culminated in the 2015 establishment of $M{\acute{e}}morial$ ACTe, Caribbean Centre of Expression and Memory of Slavery and the Slave Trade in Guadeloupe. Reflecting on those historic moments in recent French history, this paper examines major debates in French society regarding establishment of the $M{\acute{e}}morial$ ACTe. It assesses how Aleida Assmann's "cultural memory" was created with the establishment of $M{\acute{e}}morial$ ACTe and how it has contributed to the new cultural identity of French overseas territories.

Urban Air Mobility is attracting attention as a future innovation industry around the world, and leading industries are considering the application of composite materials for structural robustness and lightening in the designing and manufacturing new concept eVTOL aircraft. To apply composite materials to the new concept of eVTO aircraft, this paper was analyzed about composite material qualification system of FAA & EASA and institutionalized by Korea Government, including the procedures and methods, the organization to carry out the material verification for domestic conditions. The domestic composite material qualification system will not only make it easier for manufacturers of eVTOL aircraft with a new concept to apply composite materials to domestic aircraft through pre-material qualification, but also reduce the burden of material qualification within the period of type certification. In addition, domestic manufacturers of composite materials with qualified material quality and performance will be easy to enter for domestic aircraft applications and composite material manufacturers with experience in applying to aircraft will have a positive impact on overseas exports. This system will be able to promote the development eVTOL aircraft industry of a new concept and enhance international credibility of made aircraft in Korea.
Importance: Staphylococcus aureus and Escherichia coli contribute to global health challenges by forming biofilms, a key virulence element implicated in the pathogenesis of several infections. Objective: The study examined the efficacy of various generations of cephalosporins against biofilms developed by pathogenic S. aureus and E. coli. Methods: The development of biofilms by both bacteria was assessed using petri-plate and microplate methods. Biofilm hydrolysis and inhibition were tested using first to fourth generations of cephalosporins, and the effects were analyzed by crystal violet staining and phase contrast microscopy. Results: Both bacterial strains exhibited well-developed biofilms in petri-plate and microplate assays. Cefradine (first generation) showed 76.78% hydrolysis of S. aureus biofilm, while significant hydrolysis (59.86%) of E. coli biofilm was observed by cefipime (fourth generation). Similarly, cefuroxime, cefadroxil, cefepime, and cefradine caused 78.8%, 71.63%, 70.63%, and 70.51% inhibition of the S. aureus biofilms, respectively. In the case of E. coli, maximum biofilm inhibition (66.47%) was again shown by cefepime. All generations of cephalosporins were more effective against S. aureus than E. coli, which was confirmed by phase contrast microscopy. Conclusions and Relevance: Cephalosporins exhibit dual capabilities of hydrolyzing and inhibiting S. aureus and E. coli biofilms. First-generation cephalosporins exhibited the highest inhibitory activity against S. aureus, while the third and fourth generations significantly inhibited E. coli biofilms. This study highlights the importance of tailored antibiotic strategies based on the biofilm characteristics of specific bacterial strains.
Korean government built "2040 Science and Technology Future Vision" in order to show positive future scenarios and suggest a long-term guideline for a progress in science and technology. The S&T Future Vision was built based on an analysis of global megatrends and a prospect of domestic social change. After building S&T Future Vision, the "Government R&E Strategy"s was established as a follow-up action plan. The Government R&D Strategy consists of lists of future emerging technologies for future leadership, government R&D investment status and investment portfolio plans. Exploring future emerging technologies aggressively and making a governmental R&D strategic policy are requirements for national competitiveness, leadership in the world. Therefore search and selection for future emerging technologies is getting more and more important recently. Generally qualitative methodologies have been used such as expert-panel discussion method and portfolio analysis with expert valuation method in order to explore future technologies. These experts-based qualitative methodologies are well defined but lacking in some objectivity because size of expert-panels has limitations. We suggest a quantitative methodology, science mapping method to compensate this shortcoming in this study. There is another limitation related governmental R&D strategy which is that general R&D portfolios are static until a point of technology realization. We also propose a dynamic R&D investment portfolio which present different portfolios at a intermediate point and a point of technology realization. We expect this try with science mapping method and a dynamic R&D portfolio could strengthen strategic aspect of government R&D policy.
