The objective of this article is to compare the characteristics and the origin of Welfare State in Korea and France. This study also finds out the causes of underdevelopment of Welfare State in Korea. In the third Republic of France, the first Industrial Accident Compensation Law was legislated in 1898. The discussion of the project of Law commenced in 1880. The Parliamentary Debate on the legislation of the Law had continued for 18 years. The leaders of the debate was the group of progressive Republicans(Radicals) in the French Parliament. In Korea, it was also in the period of the third Repulic, the President and several members of the Supreme Committee of National Reconstruction (Guk-Ga-Jai-Gun-Choi-Go-Ho-Eui), the authoritative military government who enacted and developed the Social Insurance Law of Industrial Accident Compensation, the first Law of Welfare State in Korea. However, Korea and France show more differences than similarities in the terms of the origin of the Welfare State. The motivations and goals of social policies of the two countries were quite different at the beginning stage. In France, the progressive Republicans of Parliament made welfare state policies in order to maintain the politico-social hegemony and social peace by provision of economic supports to workers. In Korea, the group of military officers had begun the welfare legislation in order to win the general election and obtain political power in 1963. Comparison on the origins of the welfare states in the two countries shows similarities as well as differences in terms of the role of actors. In France, the state and the owners of big enterprises had agreed and played positive roles in the legislation of the welfare state policies. However, the owners of small companies, merchants and farmers had played negative roles. Like the French case, Korean government and owners of big enterprises had played positive roles. The state as a major actor of the legislation of the social insurance programs in the two countries are slightly different. In Korea, the owners of small companies had played negative roles in making of medical insurance programs in 1976. Comparison of the current state of two welfare states shows substantial differences in terms of the development of the welfare state. What is the reason for such differences? Why does Korean Welfare State underdevelop? Historically, the developmentalism as an major ideology of the third Republic of Korea has continually influenced the underdevelopment of the Welfare State. It implies that Koreans have to invent a new ideology of Welfare State which can replace the developmentalism and support the development of Welfare State in the future. Without such a new ideology, it is very difficult to develop an european style welfare state in Korea.

This study was conducted to suggest a sustainable farming practice forresource recycling in vegetable gardens of North Korea. In North Korea, farmers are allowed to own private vegetable gardens less than $100m^2$. However, usage of fertilizers in private vegetable gardens is very limited due to economic sanctions by UN security council. If North and South Korea initiated the cooperative action in the near future, agricultural sector would be the highest priority cooperation area. Considering the current North Korean situation in agriculture, we would like to suggest a method for producing organic fertilizer manure. For raw materials for producing manure, we selected corn byproduct, which is the most abundant material, and rabbits' feces, which are easily obtained from individual private farms in North Korea. As we cannot get corn byproducts and rabbits' feces from North Korea, we prepared samples of corn byproducts and rabbits; feces from many places in South Korea. After statistical analysis of variance, there was no significant difference in the T-N contents of corn byproducts from Gyeonggi, Gangwon, Chungnam, Chungbuk, Jeollabuk and Gyeongsangnam-dos, which indicates that the fertilizing quality of corn byproducts does not vary significantly in the spatial scale of South. Korea. In this sense, if we use corn samples from Gyeonggi province, they would not be very different from those of North Korean regions. Physicochemical properties of rabbits' feces were different between those eating feed grains and those eating plants only. Hence, we used rabbits' feces of the rabbits from Yeonchun area, which were fed by plants only. Using three different mixing ratios of corn byproducts and rabbits' feces, composting was conducted for 60 days. The mixing ratio of 1:1 produced the manure with % T-N of 1.98% and OM/N ratio of 31.7 after 30 days of composting, which is comparable to the quality of commercial manure.

In a survey in which farmers were asked about their levels of satisfaction with agricultural machines, Japanese products scored higher than local products by 1.2, 1.3, and 1.4 times for tractors, combine harvesters, and rice transplanter, respectively. Japanese products corresponded to generally high satisfaction levels in terms of operating performance, operability, frequency of breakdowns, and durability, excluding sales price and after-sales services. Effective countermeasures through quality improvement are therefore necessary for Korean products. Furthermore, a survey of dealers showed that the components and consumables for core agricultural machines had high frequencies of breakdowns and repairs. Four major components of tractors represented 85.3% of all breakdowns and repairs, five components of combine harvesters represented 89.6%, and three components of rice transplanters represented 80.5%. Moreover, a comparison of the technological levels between local and imported machines showed that the local machines' levels were at 60-100% for tractors, 70-100% for combine harvesters, and 70-95% for rice transplanters. Small and mid-sized tractors, 4 interrow combine harvesters, and 6 interrow rice transplanters showed similar levels of technology. The results of the analysis suggest that action is urgently needed at a policy level to establish an agricultural machinery component research center for the development, production, and supply of commonly-used components, with the participation of manufacturers of agricultural machines and components, in order to enhance the competitiveness of local manufacturers and to revitalize the agricultural machine market.

Early warning systems for weather risk management in the agricultural sector have been developed to predict potential wind damage to crops. These systems take into account the daily maximum wind speed to determine the critical wind speed that causes fruit drops and provide the weather risk information to farmers. In an effort to increase the accuracy of wind risk predictions, an artificial neural network for binary classification was implemented. In the present study, the daily wind speed and other weather data, which were measured at weather stations at sites of interest in Jeollabuk-do and Jeollanam-do as well as Gyeongsangbuk- do and part of Gyeongsangnam- do provinces in 2019, were used for training the neural network. These weather stations include 210 synoptic and automated weather stations operated by the Korean Meteorological Administration (KMA). The wind speed data collected at the same locations between January 1 and December 12, 2020 were used to validate the neural network model. The data collected from December 13, 2020 to February 18, 2021 were used to evaluate the wind risk prediction performance before and after the use of the artificial neural network. The critical wind speed of damage risk was determined to be 11 m/s, which is the wind speed reported to cause fruit drops and damages. Furthermore, the maximum wind speeds were expressed using Weibull distribution probability density function for warning of wind damage. It was found that the accuracy of wind damage risk prediction was improved from 65.36% to 93.62% after re-classification using the artificial neural network. Nevertheless, the error rate also increased from 13.46% to 37.64%, as well. It is likely that the machine learning approach used in the present study would benefit case studies where no prediction by risk warning systems becomes a relatively serious issue.

"Women's Nong-ak (農樂, Traditional Korean music performed by farmers)" was born together with "Maiden group." This study focuses on the reason why women appeared as principal agents of Nong-ak which was almost exclusive to men previously and especially, on the appearance of women Nong-ak Artists who was previously worked in Traditional Drama Troupe. This study empirically deals with details of activities of Maiden's (娘子) Nong-ak troupes and Girls' (少女) Nong-ak troupes through newspaper articles. Women Nong-ak Artists enjoyed popularity with their peculiar attractions. Participating in Nong-ak contests and collecting money for their performances, women Nong-ak Artists learned their skills form masters of Woodo Nong-ak and attracted attention with their colorful costumes. Women of Nong-ak circle especially saw through the trend of the time, expanded their arena of activities and exercised flexibility and ability to react quickly to changing situations while mixing with various genres. In particular, young girls were mobilized to show value and marketability of Korean culture as cultural medium who decorated "Pure Nong-ak art stage." They were no different from "Pretty dolls dancing like angels" who could not purse their interest and economic benefit or incite political cause and their patrons were domestic and overseas political figures. Women artists, who put Nong-ak on the stage in the name of Maiden's (娘子) Nong-ak troupes and Girls' (少女) Nong-ak after the liberation from Japanese colonial rule, contributed to expansion of market base. Women Nong-ak artists, who dominated a century in such troupes as Sadangpae, Hyuprulsa, Maiden's (娘子) Nong-ak troupes, Girls' (少女) Nong-ak troupes and Women Nong-ak troupes, were the very heroines who overturned the conventions of "male predominance (男尊女卑)" which filled Nong-ak arena and cultivated a new tradition of Nong-ak culture.

Baengnyeongdo Island, which belongs to Ongjin-gun, Incheon, is an island in the northernmost part of the West Sea in South Korea. Baengnyeong Island is the 15th largest island in Korea and covers an area of 51 km². The Korea Ginseng Corporation (KGC) investigated the possibility of growing ginseng on Baengnyeong Island in 1996. In 1997, thanks to the support of cultivation costs from Ongjin-gun, the first ginseng seedbed was built on Baengnyeong Island. In 1999, the seedlings were transplanted to a permanent field under a contract with KGC. In 2003, the first six-year-old ginseng harvest was performed, and KGC purchased all production according to the contract. Since then, KGC has signed on to grow ginseng until 2012 and purchased six-year-old ginseng until the fall of 2016. Since 2014, the GimpoPaju Ginseng Agricultural Cooperative Association has signed a ginseng production contract. According to a survey of nine 6-year-old ginseng fields (total 5,961 units) on Baengnyeong Island, the top five with good growth had a survival rate of 42.6 to 68%, and the bottom four with poor growth had an extremely low survival rate of 11.1 to 21.3%. The four fields with low survival rates were where hot peppers were planted before ginseng cultivation. It is believed that the excess nitrogen remaining in the soil due to the treatment of compost or manure during pepper cultivation causes ginseng roots to rot. The average incidence of Alternaria blight was 8.6%. Six six-year-old ginseng gardens were low at 1.1 to 4.7%, while the other three were high at 16.7 to 20.9%. It is assumed that the reason for the low survival rate and high incidence of Alternaria blight is a rain-leaking shield. Farmers used rain-leaking shields because the precipitation on Baengnyeong Island was smaller than on land. One field showed 3% of leaves with yellowish brown spots, a symptom of physiological disturbance of the leaf, which is presumed to be due to the excessive presence of iron in the soil. To increase the production of ginseng on Baengnyeong Island, it is necessary to develop a suitable ginseng cultivation method for the island, such as strengthening the field management based on the results of a scientific study of soil, using rain-resistant shading, and installing drip irrigation facilities. I hope that ginseng will become a new driving force for the development of Baengnyeong Island, allowing ginseng products and food to thrive in the beautiful natural environment of the island.

The experiments were carried out in farmers' field to determine the yield response of corn to fertilizers for the three years (1976-1979) The results are summarized as follow: 1. The optimum application rates of N-P-K fertilizers on corn cultivars was 21.1-11.6-10.6 kg/10a for Suweon 19, 23.0-11.9-15.0 kg/10a for Boggyo 2 and 19.8-10.6-9.1 kg/10a for Hwangok 3, and 23.3-19.1-10.7 kg/10a in drained paddy soil. 2. The optimum application rates of N-P-K fertilizers was 23.4-15.5-13.2 kg/10a in fertile soil comparing with 27.0-15.6-18.8 kg/10a in the soil of low fertility. However yield was lower in soil of low fertility than in fertile soil even under the condition applied optimum amount. 3. Production efficiencies of each kg of N, P, K application for Suweon 19, Boggyo 2, and Hwangok 3 were 26.1-24.5-9.7, 17.8-13.3-2.0, and 14.6-21.5-4.2kg. respectively. 4. The optimum nutrient content in soil and plant to yield 1,000 kg/10a of corn was available phosphorus 200 ppm, exchangeable potassium 0.63 me/100g, potassium saturation rate 5.0% in soil, and nitrogen 2.86%, phosphorus 0.73%, potassium 2.80% in plant at tasseling stage.

This study aims to analyze the impact of cement industry on region change. For this study Maepo-Eub was selected as study area, where three cement factories are located. The data for analysis were obtained from interviews, questionaire surveys and the employee list of each cement factory. The analytic procedures for this study are as follows: 1) The change of regional employment was analyzed by development was industry in terms of the permanent address, education level, occupational status of the employee. 2) The degree of population growth are analyzed by developmental staae of the industry. Some conclusions from this study follows: 1) As these cement factories were built at Maepo in the 1960's, there were plenty of employment opportunities. Thus many technicians and workers flooded in Maepo-Eub. in the 1970's with the expansion of production facilities therewere much more immigrants to the industrial region, while there were outflow in the neighboring rural areas. In the 1980's the opportunity for the employment of cement factories have been decreased due to the introduction of the automation processes and larger, sized machines. Among the employee of three cement factories the native of Chungcheongbukdo (65%; in them Danyang 52%, Jecheon 32%) is dominant, the second is from Kangwon-do (13%), and the third is from Kyungsangbuk-do (11%) adjacent to Chungcheongbuk-do. It means that there are more employment opportunity in the near places of cement factories. 2) In the period of 1960's study area had experineed rapid social increase in population by the development of cement industry. That is, cement industries created new job opportunities and attracted large population concentration into this area. In the period of 1970's the population of the industrial region have increased continuously, while the population of neighboring rural areas have decreased. In the period of 1980's the population of Maepo decreased steadily because of decrease of labour forces through automation and commuting. Thus in the early stage of idustrial development large population concentrated in the neighboring villages of cement factories, and formed residential areas, commercial areas and service areas. As agricultural and was encroached, rural people left their regions to live in the more convenient suburbs. 3) People engaged in cement industry think that cement industry has a favorable influence on regional development, such as creating job opportunity, raising income level, developing business and service sector, and leading high economic growth. While farmers and some people think that cement industries as a pollution causing factories have a harmful influence on regional development, sucha as injuring the crops, causing environmental pollution, and being harmful to health. If pollution problems are solved, I think Maepo will play an important role as a regional center which can offer employment opportunity, business and service function to pheripheral rural areas, and raise a income level.

This experiment was conducted to clear up the cause of nutrient physiological disorder and to manage of optimum fertilization for leaf perilla crop under plastic film house condition in Geum-san area in 2009. A nutrient contents of leaf perilla were analyzed during the growing stages of crop from the first harvest to the last harvest stages, and the data were going to use as the nutritional factors for farms' activity in the fields. In survey of leaf perilla growing status at five farmers' fields, it was needed 30 days for growing of 5~10 stems, 60 days for 10~15 stems and 45 days for 15~20 stems of leaf perilla. Contents of nitrogen, phosphorus and potassium in leaf and stem had been kept on some high values in early stages, but it had been decreased in gradually in late stages of growing. Nitrogen and potassium contents were more changeable in leaf than stem, and phosphorus content was kept in more both of leaf and stem than those of nitrogen and potassium. The major macro-nutrient contents of perilla leaf on first of July were 6.34 in N, 0.54 in P, 2.48 in K, 1.98 in Ca and 0.62% in Mg, total uptake amounts of major three elements were $400kg\;ha^{-1}$ in N, $30kg\;ha^{-1}$ in P and $250kg\;ha^{-1}$ in K. Total yield of perilla leaf was $52,000kg\;ha^{-1}$, and total dry matter was $10,510kg\;ha^{-1}$ with $8,680kg\;ha^{-1}$ in leaf dry matter and $1,830kg\;ha^{-1}$ in stem dry matter.

A microbial insecticide "Bt-Plus" has been developed to enhance an insecticidal efficacy of an entomopathogenic bacterium, Bacillus thuringiensis (Bt). However, its wettable powder formulation is not preferred by farmers and industry producers due to relatively high cost. This study aimed to develop a soluble concentrate formulation of Bt-Plus. To this end, an optimal mixture ratio of two bacterial culture broths was determined to be 5:4 (v/v) of Bt and Xenorhabdus nematophila (Xn) along with 10% ethanol preservative. In addition, Bt broth was concentrated by 10 times to apply the mixture at 1,000 times fold dilution. The resulting liquid formulation was sprayed on cabbage crop field infested by late instar larvae of the diamondback moth, Plutella xylostella. The field assay showed about 77% control efficacy at 7 days after treatment, which was comparable to those of current commercial biopesticides targeting P. xylostella. For storage test in both low and room temperatures, the liquid formation showed a relatively stable control efficacy at least for a month. To develop a quality control technique to exhibit a stable control efficacy of Bt-Plus, Bt spore density ($5{\times}10^{11}$ spores/mL) and eight active component concentrations of Xn bacterial metabolites in the formulation products have been proposed in this study.
