Many methods are available to measure leaf area index(LAI) directly and are variations of either Leaf area index(LAI) and leaf angle distribution are widely used indices of canopy structure that are difficult to measure directly. Direct measurements of canopy structure are tedious and labor intensive in small canopies and nearly impossible in large forest canopies. This study introduced fundamental theories in LAI measurements and applied that for several crops.

History , achievement and future of direct-wet-rice-seeding technique in Korea and problems encountered in on-farming research were introduced. Some farmers are very eager to lower production cost and save labor. Their effort results in several direct-wet-seeding methods and seeding machines. The design problems and improvement points related to the direct -wet-rice-seeding machines were drawn out of field test.

The rapid progress of information technology makes the 3rd digital revolution after the 1st agricultural and the 2nd industrial revolution in the human history. The 1st agricultural-oriented society was based on the land and the labor, the 2nd industrial-oriented society was based on the capital and the technology 3rd knowledge-information-oriented society is where to make profit from creative brainworks and ideas based on human beings. The core of the knowledge-information-oriented society is the digital revolution from digitalizing information such as increase of the various digital contents in geometrical progression through internet.

One of the most important factors influencing the outbreak and severity of foliar diseases is the duration of wetness from dew deposition, rainfall, or irrigation. Models may provide good alternatives for assessing leaf wetness duration (LWD) without the labor, cost, and inconvenience of making measurements with sensors.(omitted)

As the typical farming of the most Asian countries are of small and subsisting scale, the infrastructure is variable depending on the region and more complicated than in the industrialized countries. Except such basic statistics as acreage of farm land, farming population and production, there are no common standard methods to be used for indepth analysis on the farming status, the level of farming techniques, financial status of farming, consciousness of farmers and others. Therefore, it is necessary to develop survey models which can be commonly used to compare with different circumstances. The purpose of this report is to provide examples of survey models which are used to measure farming performances in Korea. Those are (1) Diagnosis and analysis on farming technique, labor utilization and farm income, (2) Management performance analysis, (3) Planning for farming, (4) Survey on the nutritional status of farming, (5) Survey on rural village status and planning regional agricultural development.

The development and improvement of the originally designed direct rice sowing machine were carried out for the specific purpose of saving labor and increasing the efficiency of field operations in rice cultivation in the northern part of Japan. the prototype super wide spreader has a unique mechanism which propels rice seeds by compressed air and spreads them from the pivoting nozzle while the machine is in motion. The effective field capacity of sowing operation is about 6 ha/h. This spreader can also handle granular chemicals such as fertilizers, herbicides, pesticides and insecticides.

This study analyzed management situations of two organizations that have produced environment-friendly agricultural and processed meat products. 'A' farming corporation sells environment-friendly agricultural products like as grains, vegetables, fruits and processing foods. 'B' agricultural corporation processes and sells environment-friendly processed meat products, specially organic and antibiotic-free beef products. Recently, members and production areas of 'A' farming corporation have decreased because of their aging and labor shortage. And Indices for the management analysis are stability ratio, activity ratio and profitability ratio. Stability ratio indices are debt ratio, net worth ratio, fixed ratio and current ratio. Activity ratio ones include fixed assets turnover and net worth turnover. And profitability ratio is showed through return on investment, net return on sales and return on equity.

Anna Letitia Barbauld's poem "Washing-Day" (1797) has sparked a variety of feminist critical endeavors over the past two decades. While many feminist literary critics try to salvage the poem as a successful tongue-in-cheek riposte directed at the male dominant literary world, more rigorous Marxist feminists accuse Barbauld of being limited by her own middle-class woman's view on women's domestic labor. Legitimate as they may be, these readings fail to elucidate Barbauld's place in a larger literary and intellectual discourse during the eighteenth century. In this paper I read "Washing-Day" as a woman's georgic, a genre or mode concerned with agricultural labor, the public value of which was highly recognized in eighteenth-century England. Alluding to canonical texts by writers like Shakespeare, Milton, and Pope, Barbauld's "loaded lines" in mock-heroic form create a space in which the women's domestic labor of washing interrupts men's daily routines and disrupts their poetic assumptions. While she makes women's work visible, Barbauld also addresses its quintessential nature. Women's work is affective labor; women have to labor physically and mentally to produce the desired domestic comfort. By allowing the image of the soap "bubble" to echo with many "bubbles" in other writers' texts, from the soap bubbles the narrator used to play with as a child to the hot-air balloon "bubble" of the Montgolfier brothers, Barbauld pleasantly equates work and day-dreaming, men's toil and children's play, and finally public, scientific, and recognized labor and private, domestic, and imaginative activities.

This study was conducted to solve the problem of spinach harvesting done by manpower at the outdoor field during the cold winter season. Prototype spinach harvester was designed to dig, pick-up, and collect in a continuous operation for harvesting outdoor field-planted crawling type spinach. In the field test, two types of blades (Type A : angle of $150^{\circ}$, Type B : straight) were used for measuring the cutting loads of spinach and chain conveyor with lugs was used for picking up the root cut spinach. Prototype's vibrating blade reduced the digging power of the fixed blade by $46\%$. The loss was also very little ($0.7\%$) with a digging depth of 4 cm, an oscillation frequency of 748 rpm, and an oscillation distance of 33 mm. The working performance of the prototype spinach harvester was 38 hour/ha resulting to $96\%$ labor cost reduction compared to the conventional harvesting.
